3 to the terminal. The
If you need multiple I/O actions in one expression, you can use a
do block. Actions are separated by semicolons.
Prelude>
do { putStr "2 + 2 = " ; print (2 + 2) }2 + 2 = 4 Prelude>
do { putStrLn "ABCDE" ; putStrLn "12345" }ABCDE 12345
Reading can be done with
getLine (which gives back a
String) or
readLn (which gives back whatever type of value you want). The
<- symbol is used to assign a name to the result of an I/O action.
Prelude>
do { n <- readLn ; print (n^2) expression as a bonus.
The first non-space character after
do is special. In this case, it's the p from
putStrLn. Every line that starts in the same column as that
p is another statement in the
do block. If you indent more, it's part of the previous statement. If you indent less, it ends the
do block. This is called "layout", and Haskell uses it to avoid making you put in statement terminators and braces all the time. (The
then and
else phrases have to be indented for this reason: if they started in the same column, they'd be separate statements, which is wrong.)
(Note: Do not indent with tabs if you're using layout. It technically still works if your tabs are 8 spaces, but it's a bad idea. Also, don't use proportional fonts -- which apparently some people do, even when programming!)
4 Simple types
So far, not a single type declaration has been mentioned. That's because Haskell does type inference. You generally don't have to declare types unless you want to. If you do want to declare types, you use
:: to do it.
Prelude>
5 :: Int5 Prelude>
5 :: Double5Prelude> :t
'X'
'X' :: CharPrelude> :t
"Hello, Haskell"
"Hello, Haskell" :: [Char]
(In case you noticed,
[Char] is another way of saying
String. See the section on lists later.)
Things get more interesting for numbers.
Prelude> :t
42
42 :: (Num t) => tPrelude> :t
42.0
42.0 :: (Fractional t) => tPrelude> :t
gcd 15 20
gcd 15 20 :: (Integral t) => t
These types use "type classes." They mean:
42can be used as any numeric type. (This is why I was able to declare
5as either an
Intor a
Doubleearlier.)
42.0can be any fractional type, but not an integral type.
gcd 15 20(which is a function call, incidentally) can be any integral type, but not a fractional type.
There are five numeric types in the Haskell "prelude" (the part of the library you get without having to import anything):
Intis an integer with at least 30 bits of precision.
Integeris an integer with unlimited precision.
Floatis a single precision floating point number.
Doubleis a double precision floating point number.
Rationalis a fraction type, with no rounding error.
All five are instances of the
Num type class. The first two are instances of
Integral, and the last three are instances of
Fractional.
Putting it all together,
Prelude>
gcd 42 35 :: Int7 Prelude>
gcd 42 35 :: Double<interactive>:1:0: No instance for (Integral Double)
The final type worth mentioning here is
(), pronounced "unit." It only has one value, also written as
() and pronounced "unit."
Prelude>
()
()Prelude> :t
()
() :: ()
You can think of this as similar to the void keyword in C family languages. You can return
() from an I/O action if you don't want to return anything.
: operator appends an item to the beginning of a list. (It is Haskell's version of the cons function in the Lisp family of languages.)
zip, a library function that turns two lists into a list of tuples.Prelude>
snd (1, 2)
2Prelude>
map fst [(1, 2), (3, 4), (5, 6)]
[1,3,5]
Also see how to work on lists
6 Function definitions
We wrote a definition of an IO action earlier, called
main:
main = do putStrLn "What is 2 + 2?" x <- readLn if x == 4 then putStrLn "You're right!" else putStrLn "You're wrong!"
Now, let's supplement it by actually writing a function definition and call it
factorial. I'm also adding a module header, which is good form.
factorial 5 without needing parentheses.
Now ask ghci for the type.
$ ghci Test.hs << GHCi banner >> Ok, modules loaded: Main. Prelude Main> :t
factorial
factorial :: (Num a) => a -> a
Function types are written with the argument type, then
->, then the result type. (This also has the type class
The
let expression defines temporary names. (This is using layout again. You could use {braces}, and separate the names with semicolons, if you prefer.)
classify age = case age of 0 -> "newborn" 1 -> "infant" 2 -> "toddler" _ -> "senior citizen"
The
case expression does a multi-way branch. The special label
_ means "anything else".
The
import says to use code from
Data.Map and that it will be prefixed by
M. (That's necessary because some of the functions have the same names as functions from the prelude. Most libraries don't need the
as part.) | http://www.haskell.org/haskellwiki/Learn_Haskell_in_10_minutes | crawl-002 | refinedweb | 834 | 75.1 |
Well recently I had nasty worm/rootkit problem and naturally I wanted to know what he changed in my system. So i started seeking for some tool to detect registry changes. some simple tool to dump complete registry content to text file before infection and after and by simple text diff i would be able to see the changes fast. I was not very lucky thou. Since all reg tools i found were using win32 api to get data which that clever rootkit redirected to himself and thus stayed hidden. Also as i later found out malware don't even need to be that clever to hide things in registry from standard api.
So now I had physical clean registry files from system restore point and dirty ones from my infected system. And I didn't stop poking in the hives until I did come up with simple tool to dump and compare their real contents in simple text format. I also needed full reg path at each entry so in case I use text diff on those dumps I see where the change happened.
NT/XP registry files (binary hives not textual reg files) are actually very simple. tey are just bunch of 4k blocks where each block contain variable sized blocks . Each of those starts with
usual 4b size and 2b type.
And thats about it . thats ms registry hive format. Oh and I nearly forgot. First 1k of first block is hive header with no usefull info as far as i know
So there are 2 basic blocks one for keys and one for values. what's nice is that MS decided to use human readable 2 char strings in the block type field i mentioned earlier. so if you open hive in hex viewer jou can clearly see "nk" for key block and "vk" for value block.
And here is actual code to dump registry hives. I used portable c code so it should be compilable on unix too without much change.
#include <string.h> #include <stdio.h> #include <stdlib.h> struct offsets { long block_size; char block_type[2]; // "lf" "il" "ri" short count; long first; long hash; }; struct key_block { long block_size; char block_type[2]; // "nk" char dummya[17]; int subkey_count; char dummyb[4]; int subkeys; char dummyc[4]; int value_count; int offsets; char dummyd[28]; short len; short du; char name; }; struct value_block { long block_size; char block_type[2]; // "vk" short name_len; long size; long offset; long value_type; short flags; short dummy; char name; }; void walk ( char* path, key_block* key ) { static char* root=(char*)key-0x20, *full=path; // add current key name to printed path memcpy(path++,"/",2); memcpy(path,&key->name,key->len); path+=key->len; // print all contained values for(int o=0;o<key->value_count;o++){ value_block* val = (value_block*)(((int*)(key->offsets+root+4))[o]+root); // we skip nodes without values if(!val->offset) continue; // data are usually in separate blocks without types char* data = root+val->offset+4; // but for small values MS added optimization where // if bit 31 is set data are contained wihin the key itself to save space if(val->size&1<<31) { data = (char*)&val->offset; } // notice that we use memcopy for key/value names everywhere instead of strcat // reason is that malware/wiruses often write non nulterminated strings to // hide from win32 api *path='/'; if(!val->name_len) *path=' '; memcpy(path+1,&val->name,val->name_len); path[val->name_len+1]=0; printf("%s [%d] = ",full,val->value_type); for(int i=0;i<(val->size&0xffff);i++) { // print types 1 and 7 as unicode strings if(val->value_type==1||val->value_type==7) { if(data[i]) putchar(data[i]); // and rest dump as binary data } else { printf("%02X",data[i]); } } printf("\n"); } // for simplicity we can imagine keys as directories in filesystem and values // as files. // and since we already dumped values for this dir we will now iterate // thru subdirectories in the same way offsets* item = (offsets*)(root+key->subkeys); for(int i=0;i<item->count;i++){ // in case of too many subkeys this list contain just other lists offsets* subitem = (offsets*)((&item->first)[i]+root); // usual directory traversal if(item->block_type[1]=='f') { // for now we skip hash codes (used by regedit for faster search) walk(path,(key_block*)((&item->first)[i*2]+root)); } else for(int j=0;j<subitem->count;j++) { // also ms had chosen to skip hashes altogether in this case walk(path,(key_block*)((&subitem->first)[j]+root)); } } } int main(int argc, char** argv) { char path[0x1000]={0}, *data; FILE* f; int size; if(argc<2||!(f=fopen(argv[1],"rb"))) return printf("hive path err"); fseek(f,0,SEEK_END); if(!(size=ftell(f))) return printf("empty file"); rewind(f); data=(char*)malloc(size); fread(data,size,1,f); fclose(f); // we just skip 1k header and start walking root key tree walk(path,(key_block*)(data+0x1020)); free(data); return 0; }
Remember it will dump values that you normally don't even have access to so be careful.
It's prerfect to just dump the hives before and after software installation and just compare changes with text diff (for example commandline version from UnixUtils is great) .

11 October 2012 11:09 [Source: ICIS news]
SINGAPORE (ICIS)--Chinese oil majors Sinopec and PetroChina are expected to refine a total of about 30.5m tonnes of crude in October, with daily throughput flat with September’s level of about 984,000 tonnes, sources from both companies said on Thursday.
Sinopec’s crude throughput target for October is 18.15m-18.25m tonnes, with its daily throughput up by 0.43% month on month to around 587,000 tonnes.
The increase comes mainly from its ?xml:namespace>
Its 100,000 bbl/day
In addition, its 160,000 bbl/day Qilu refinery was shut on 8 October for a 25-day maintenance.
PetroChina plans to process 12.25m-12.35m tonnes of crude in October, with its daily throughput down by 0.6% to about 397,000 tonnes.
The decrease is primarily because its 200,000 bbl/day joint venture refinery in Dalian and its 120,000 bbl/day Daqing refinery will both cut operating rates this month amid the weak market, said a company source. | http://www.icis.com/Articles/2012/10/11/9602966/sinopec-petrochina-keep-october-daily-crude-throughput-unchanged.html | CC-MAIN-2014-41 | refinedweb | 176 | 74.59 |
Linus Torvalds's Double Pointer Problem
519 54 55141
In 2012, Linus Torvalds presented an 'intuitive' way to use double pointers to easily remove a node from a linked list. But how intuitive can double pointers even really be? I present a way of visualizing pointers that I do not see often presented, but works very well for me when trying to figure out the jungles of addresses, dereferences, and other commands a complex C program can use.
Explanation by video
This problem has been discussed by Philip Buuck in this YouTube video. I recommend you to watch this if you need more detailed explanation.
Explanation by example
If you like learning from examples, I prepared one. Let's say that we have the following single-linked list:
that is represented as follows (click to enlarge):
We want to delete the node with the
value = 8.
Code
Here is the simple code that do this:
#include <assert.h> #include <stdio.h> #include <stdlib.h> struct node_t { int value; node_t *next; }; node_t* create_list() { int test_values[] = { 28, 1, 8, 70, 56 }; node_t *new_node, *head = NULL; int i; for (i = 0; i < 5; i++) { new_node = (node_t*)malloc(sizeof(struct node_t)); assert(new_node); new_node->value = test_values[i]; new_node->next = head; head = new_node; } return head; } void print_list(const node_t *head) { for (; head; head = head->next) printf("%d ", head->value); printf("\n"); } void destroy_list(node_t **head) { node_t *next; while (*head) { next = (*head)->next; free(*head); *head = next; } } void remove_from_list(int val, node_t **head) { node_t *del, **p = head; while (*p && (**p).value != val) p = &(*p)->next; // alternatively: p = &(**p).next if (p) { // non-empty list and value was found del = *p; *p = del->next; del->next = NULL; // not necessary in this case free(del); } } int main(int argc, char **argv) { node_t *head; head = create_list(); print_list(head); remove_from_list(8, &head); print_list(head); destroy_list(&head); assert (head == NULL); return EXIT_SUCCESS; }
If you compile and run this code you'll get:
56 70 8 1 28 56 70 1 28
Explanation of the code
Let's create
**p 'double' pointer to
*head pointer:
Now let's analyze how
void remove_from_list(int val, node_t **head) works. It iterates over list as long as
*p && (**p).value != val.
In this example given list contains value that we want to delete (which is
8).
(**p).value is
8, so we stop iterating.
Note that
*p points to the variable
node_t *next within
node_t that is before the
node_t that we want to delete (which is
**p).
Now let's assign the address of the element that we want to remove (
del->value == 8) to the
*del pointer.
We need to fix the
*p pointer so that
**p was pointing to the one element after
*del element that we are going to delete:
In the code above we call
free(del), thus it's not necessary to set
del->next to
NULL, but if we would like to return the pointer to the element 'detached' from the list instead of the completely removing it, we would set
del->next = NULL:
As @R. Martinho Fernandes pointed out in his answer, using pointer to pointer as an argument in
void push(struct node** head, int data) allows you to change the
head pointer directly from within
push function instead of returning the new pointer.
There is yet another good example which shows why using pointer to pointer instead a single pointer may shorten, simplify and speed up your code. You asked about adding a new node to the list which probably typically doesn't need pointer-to-pointer in contrast to removing the node from the singly-linked list. You can implement removing node from the list without pointer-to-pointer but it is suboptimal. I described the details here. I recommend you also to watch this YouTube video which addresses the problem.
BTW: If you count with Linus Torvalds opinion, you would better learn how to use pointer-to-pointer. ;-)

I'm trying to emulate Excel's
Insert>Scatter>Scatter with smooth lines and markers
command in Matplotlib
The scipy function interpolate creates a similar effect, with some nice examples of how to simply implement this here:
How to draw cubic spline in matplotlib
However Excel's spline algorithm is also able to generate a smooth curve through just three points (e.g. x = [0,1,2] y = [4,2,1]); and it isn't possible to do this with cubic splines.
I have seen discussions that suggest that the Excel algorithm uses Catmull-Rom splines; but don't really understand these, or how they could be adapted to Matplotlib:
Is there a simple way of modifying the above examples to achieve smooth curves through three or more points using the interpolate library?
Many thanks
By now you may have found the Wikipedia page for the Centripetal Catmull-Rom spline, but in case you haven't, it includes this sample code:
import numpy import matplotlib.pyplot as plt def CatmullRomSpline(P0, P1, P2, P3, nPoints=100): """ P0, P1, P2, and P3 should be (x,y) point pairs that define the Catmull-Rom spline. nPoints is the number of points to include in this curve segment. """ # Convert the points to numpy so that we can do array multiplication P0, P1, P2, P3 = map(numpy.array, [P0, P1, P2, P3]) # Calculate t0 to t4 alpha = 0.5 def tj(ti, Pi, Pj): xi, yi = Pi xj, yj = Pj return ( ( (xj-xi)**2 + (yj-yi)**2 )**0.5 )**alpha + ti t0 = 0 t1 = tj(t0, P0, P1) t2 = tj(t1, P1, P2) t3 = tj(t2, P2, P3) # Only calculate points between P1 and P2 t = numpy.linspace(t1,t2,nPoints) # Reshape so that we can multiply by the points P0 to P3 # and get a point for each value of t. t = t.reshape(len(t),1) A1 = (t1-t)/(t1-t0)*P0 + (t-t0)/(t1-t0)*P1 A2 = (t2-t)/(t2-t1)*P1 + (t-t1)/(t2-t1)*P2 A3 = (t3-t)/(t3-t2)*P2 + (t-t2)/(t3-t2)*P3 B1 = (t2-t)/(t2-t0)*A1 + (t-t0)/(t2-t0)*A2 B2 = (t3-t)/(t3-t1)*A2 + (t-t1)/(t3-t1)*A3 C = (t2-t)/(t2-t1)*B1 + (t-t1)/(t2-t1)*B2 return C def CatmullRomChain(P): """ Calculate Catmull Rom for a chain of points and return the combined curve. """ sz = len(P) # The curve C will contain an array of (x,y) points. C = [] for i in range(sz-3): c = CatmullRomSpline(P[i], P[i+1], P[i+2], P[i+3]) C.extend(c) return C
which nicely computes the interpolation for
n >= 4 points like so:
points = [[0,1.5],[2,2],[3,1],[4,0.5],[5,1],[6,2],[7,3]] c = CatmullRomChain(points) px, py = zip(*points) x, y = zip(*c) plt.plot(x, y) plt.plot(px, py, 'or')
resulting in this
matplotlib image:
Alternatively, there is a
scipy.interpolate function for
BarycentricInterpolator that appears to do what you're looking for. It is rather straightforward to use and works for cases in which you have only 3 data points.
from scipy.interpolate import BarycentricInterpolator # create some data points points1 = [[0, 2], [1, 4], [2, -2], [3, 6], [4, 2]] points2 = [[1, 1], [2, 5], [3, -1]] # put data into x, y tuples x1, y1 =zip(*points1) x2, y2 = zip(*points2) # create the interpolator bci1 = BarycentricInterpolator(x1, y1) bci2 = BarycentricInterpolator(x2, y2) # define dense x-axis for interpolating over x1_new = np.linspace(min(x1), max(x1), 1000) x2_new = np.linspace(min(x2), max(x2), 1000) # plot it all plt.plot(x1, y1, 'o') plt.plot(x2, y2, 'o') plt.plot(x1_new, bci1(x1_new)) plt.plot(x2_new, bci2(x2_new)) plt.xlim(-1, 5)
Another option within
scipy is akima interpolation via
Akima1DInterpolator. It is as easy to implement as Barycentric, but has the advantage that it avoids large oscillations at the edge of a data set. Here's a few test cases that exhibit all the criteria you've asked for so far.
from scipy.interpolate import Akima1DInterpolator x1, y1 = np.arange(13), np.random.randint(-10, 10, 13) x2, y2 = [0,2,3,6,12], [100,50,30,18,14] x3, y3 = [4, 6, 8], [60, 80, 40] akima1 = Akima1DInterpolator(x1, y1) akima2 = Akima1DInterpolator(x2, y2) akima3 = Akima1DInterpolator(x3, y3) x1_new = np.linspace(min(x1), max(x1), 1000) x2_new = np.linspace(min(x2), max(x2), 1000) x3_new = np.linspace(min(x3), max(x3), 1000) plt.plot(x1, y1, 'bo') plt.plot(x2, y2, 'go') plt.plot(x3, y3, 'ro') plt.plot(x1_new, akima1(x1_new), 'b', label='random points') plt.plot(x2_new, akima2(x2_new), 'g', label='exponential') plt.plot(x3_new, akima3(x3_new), 'r', label='3 points') plt.xlim(-1, 15) plt.ylim(-10, 110) plt.legend(loc='best') | https://codedump.io/share/r4pxBW329V7k/1/emulating-excel39s-quotscatter-with-smooth-curvequot-spline-function-in-matplotlib-for-3-points | CC-MAIN-2017-09 | refinedweb | 803 | 65.93 |
One common programming question is how to randomly shuffle an array of numbers in-place. There are a few wrong answers to this question - some simple shuffles people tend to think of immediately turn out to be inadequate. In particular, the most common naive algorithm that comes up is [1]:
naive_shuffle(arr): if len(arr) > 1: for i in 0 .. len(arr) - 1: s = random from inclusive range [0:len(arr)-1] swap arr[s] with arr[i]
This algorithm produces results that are badly skewed. For more information consult this post by Jeff Attwood, and this SO discussion.
The correct answer is to use the Fisher-Yates shuffle algorithm:
fisher_yates_shuffle(arr): if len(arr) > 1: i = len(arr) - 1 while i > 0: s = random from inclusive range [0:i] swap arr[s] with arr[i] i--
It was first invented as a paper-and-pencil method back in 1938, and later was popularized by Donald Knuth in Volume II of TAOCP. For this reason it's also sometimes called the Fisher-Yates-Knuth algorithm. In this article I don't aim to compare Fisher-Yates to the naive algorithm. Nor do I plan to explain why the naive shuffle doesn't work. Others have done it before me, see the references to Jeff's post and the SO discussion above.
What I do plan to do, however, is to explain why the Fisher-Yates algorithm works. To put it more formally, why given a good random-number generator, the Fisher-Yates shuffle produces a uniform shuffle of an array in which every permutation is equally likely. And my plan is not to prove the shuffle's correctness mathematically, but rather to explain it intuitively. I personally find it much simpler to remember an algorithm once I understand the intuition behind it.
An analogy
Imagine a magician's hat:
And a bunch of distinct balls. Let's take pool balls for the example:
Suppose you place all those balls into the hat [2] and stir them really well. Now, you look away and start taking balls randomly out of the hat and placing them in a line. Assuming the hat stir was random and you can't distinguish the balls by touch alone, once the hat is empty, the resulting line is a random permutation of the balls. No ball had a larger chance of being the first in line than any other ball. After that, all the remaining balls in the hat had an equal chance of being the second in line, and so on. Again, this isn't a rigorous proof, but the point of this article is intuition.
If you understand why this procedure produces a random shuffle of the balls, you can understand Fisher-Yates, because it is just a variation on the same theme.
The intuition behind Fisher-Yates shuffling
The Fisher-Yates shuffle performs a procedure similar to pulling balls at random from a hat. Here's the algorithm once again, this time in my favorite pseudo-code format, Python [3]:
def fisher_yates(arr): if len(arr) > 1: i = len(arr) - 1 while i > 0: s = randint(0, i) arr[i], arr[s] = arr[s], arr[i] i -= 1
The trick is doing it in-place with no extra memory. The following illustration step by step should explain what's going on. Let's start with an array of 4 elements:
The array contains the letters a, b, c, d at indices [0:3]. The red arrow shows where i points initially. Now, the initial step in the loop picks a random index in the range [0:i], which is [0:3] in the first iteration. Suppose the index 1 was picked, and the code swaps element 1 with element 3 (which is the initial i). So after the first iteration the array looks like this:
Notice that I colored the part of the array to the right of i in another color. Here's spoiler: The blue part of the array is the hat, and the orange part is the line where the random permutation is being built. Let's make one more step of the loop. A random number in the range [0:2] has to be picked, so suppose 2 is picked. Therefore, the swap just leaves the element at index 2 in its original place:
We make one more step. Suppose 0 is picked at random from [0:1] so elements at indices 0 and 1 are swapped:
At this point we're done. There's only one ball left in the hat, so it will be surely picked next. This is why the loop of the algorithm runs while i > 0 - once i reaches 0, the algorithm finishes:
So, to understand why the Fisher-Yates shuffling algorithm works, keep in mind the following: the algorithm makes a "virtual" division of the array it shuffles into two parts. The part at indices [0:i] is the hat, from which elements will be picked at random. The part to the right of i (that is, [i+1:len(arr)-1]) is the final line where the random permutation is being formed. In each step of the algorithm, it picks one element from the hat and adds it to the line, removing it from the hat.
Some final notes:
- Since all the indices [0:i] are in the hat, the selection can pick i itself. In such case there's no real swapping being done, but the element at index i moves from the hat and to the line. Having the selection from range [0:i] is crucial to the correctness of the algorithm. A common implementation mistake is to make this range [0:i-1], which causes the shuffle to be non-uniform.
- The vast majority of implementations you'll see online run the algorithm from the end of the array down. But this isn't set in stone - it's just a convention. The algorithm will work equally well with i starting at 0 and running until the end of the array, picking items in the range [i:len(arr)-1] at each step.
Conclusion
Random shuffling is important for many applications. Although it's a seemingly simple operation, it's easy to do wrong. The Internet is abound with stories of gambling companies losing money because their shuffles weren't random enough.
The Fisher-Yates algorithm produces a uniform shuffling of an array. It's optimally efficient both in runtime (running in O(len(arr))) and space (the shuffle is done in-place, using only O(1) extra memory).
In this article I aimed to explain the intuition behind the algorithm, firmly believing that a real, deep understanding of something [4] is both intellectually rewarding and useful.

Hello, This is on sparc-solaris. I was trying to reproduce another error that our testsuite occasionally reports (without much success :-(). I noticed while running the test repeatedly within the same debugger process (that is: repeatedly doing "run; [...]; kill" instead of starting a new debugger every time) that it would eventually cause another error in the debugger. The debugger would be telling us that it is unable to find a given thread in the procinfo list. In other words, the debugger received an event for LWP=1 and then failed to create the assocated thread element in the procinfo list. After some investgation, it turned out that this was because we were unable to open the associated lwp file in the /proc filesystem, and that was because we ran out of file descriptors! Digging further, I found that we leak the file descriptor created when opening the procfs map file. we create a cleanup routine to make sure that the associated file descriptor gets closed, but we never call the cleanup. gdb/ChangeLog: * procfs.c (iterate_over_mappings): Call do_cleanups before returning. Fixed thusly. Seems fairly straightforward, except that the cleanup is only really needed when NEW_PROC_API is defined (basically, Solaris except old versions). But I think that #ifdef code is ugly, so I made the cleanup run regardless...

USING SETER IN NCAR GRAPHICS¶
There are specific conventions for the use of SETER within NCAR Graphics, as follows:
- -
- All detectable errors shall be recoverable, in the sense described above. (That is, in every call to SETER, the final argument shall be a 1, rather than a 2.) This is by request of the folks doing NCAR Interactive, who rightly consider STOPs in the utilities undesirable. The idea is to let the user decide what is to be done about the various error conditions.
- -
- Whenever an NCAR Graphics routine calls a lower-level routine that might detect an error and call SETER, it should subsequently use ICFELL to check the error state; if a recoverable error has occurred, it should first do required clean-up chores, if possible, and then pass control back to the routine that called it. In all such uses of ICFELL, the first argument should be the name of the routine referencing ICFELL and the second argument should be a new number for the error, reflecting the position of the reference to the lower-level routine in the upper-level routine.
- -
- Any NCAR Graphics routine that can be called by a user and that can potentially yield a call to SETER must immediately check the error state and, if that error state is non-zero, return control without doing anything else. This is most conveniently done using a reference to ICFELL; see the second example in the "Usage" section of the description of ICFELL. All such references should have a first argument of the form 'XXXXXX - UNCLEARED PRIOR ERROR', where "XXXXXX" is the name of the routine in which the reference occurs, and a second argument equal to "1".
- -
- It is recommended that, within a given utility routine, the error numbers in references to SETER and ICFELL should start at 1 and increment by 1. These numbers generally have no intrinsic meaning in and of themselves: they are merely intended to allow a consultant to find the reference that generated a given error.
- -
- NCAR Graphics routines are not required to turn recovery mode on before calling a lower-level routine that might call SETER (which was the convention in the PORT library, as described in the PORT document). Instead, the assumption is that it is the responsibility of the user of NCAR Graphics to set recovery mode if he/she desires to do recovery. Since, by default, recovery mode is turned off, all NCAR Graphics calls to SETER will be treated as fatal: the error message will be printed and execution will be terminated. Once the user turns recovery mode on, however, no NCAR Graphics error will be treated in this way except for one that the user fails to recover from.
Note: These conventions are being adopted as of December 2, 1993, and represent a goal for the future. The current situation is somewhat muddled: In some utilities, all SETER calls are fatal ones. In other utilities, some SETER calls are fatal and some are not. In other utilities, no SETER calls are fatal. In general, errors at a lower level are not detected and passed back up the call chain. Users have complained (and rightly so) that error recovery is, in general, not possible; observance of these conventions should help to fix the situation. at least the following things might been changed: 1) the current SET call; 2) the current polyline color index; 3) the current polymarker color index; 4) the current text color index; 5) the current fill area color index; 6) the current dash pattern.
ACCESS¶
To use the Error_handling C or Fortran routines, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.

Savitzky Golay Filtering
The Savitzky Golay filter is a particular type of low-pass filter, well adapted for data smoothing. For further information see: (or for a pre-numpy implementation).
Sample Code
1 def savitzky_golay(y, window_size, order, deriv=0, rate=1): 2 r"""Smooth (and optionally differentiate) data with a Savitzky-Golay filter. 3 The Savitzky-Golay filter removes high frequency noise from data. 4 It has the advantage of preserving the original shape and 5 features of the signal better than other types of filtering 6 approaches, such as moving averages techniques. 7 Parameters 8 ---------- 9 y : array_like, shape (N,) 10 the values of the time history of the signal. 11 window_size : int 12 the length of the window. Must be an odd integer number. 13 order : int 14 the order of the polynomial used in the filtering. 15 Must be less then `window_size` - 1. 16 deriv: int 17 the order of the derivative to compute (default = 0 means only smoothing) 18 Returns 19 ------- 20 ys : ndarray, shape (N) 21 the smoothed signal (or it's n-th derivative). 22 Notes 23 ----- 24 The Savitzky-Golay is a type of low-pass filter, particularly 25 suited for smoothing noisy data. The main idea behind this 26 approach is to make for each point a least-square fit with a 27 polynomial of high order over a odd-sized window centered at 28 the point. 29 Examples 30 -------- 31 t = np.linspace(-4, 4, 500) 32 y = np.exp( -t**2 ) + np.random.normal(0, 0.05, t.shape) 33 ysg = savitzky_golay(y, window_size=31, order=4) 34 import matplotlib.pyplot as plt 35 plt.plot(t, y, label='Noisy signal') 36 plt.plot(t, np.exp(-t**2), 'k', lw=1.5, label='Original signal') 37 plt.plot(t, ysg, 'r', label='Filtered signal') 38 plt.legend() 39 plt.show() 40 References 41 ---------- 42 ..

Code explanation
In lines 61-62 the coefficients of the local least-square polynomial fit are pre-computed. These will be used later at line 68, where they will be correlated with the signal. To prevent spurious results at the extremes of the data, the signal is padded at both ends with its mirror image, (lines 65-67).

A wrapper for cyclic voltammetry data
One of the most popular applications of S-G filter, apart from smoothing UV-VIS and IR spectra, is smoothing of curves obtained in electroanalytical experiments. In cyclic voltammetry, voltage (being the abcissa) changes like a triangle wave. And in the signal there are cusps at the turning points (at switching potentials) which should never be smoothed. In this case, Savitzky-Golay smoothing should be done piecewise, ie. separately on pieces monotonic in x:
def savitzky_golay_piecewise(xvals, data, kernel=11, order =4): turnpoint=0 last=len(xvals) if xvals[1]>xvals[0] : #x is increasing? for i in range(1,last) : #yes if xvals[i]<xvals[i-1] : #search where x starts to fall turnpoint=i break else: #no, x is decreasing for i in range(1,last) : #search where it starts to rise if xvals[i]>xvals[i-1] : turnpoint=i break if turnpoint==0 : #no change in direction of x return savitzky_golay(data, kernel, order) else: #smooth the first piece firstpart=savitzky_golay(data[0:turnpoint],kernel,order) #recursively smooth the rest rest=savitzky_golay_piecewise(xvals[turnpoint:], data[turnpoint:], kernel, order) return numpy.concatenate((firstpart,rest))
Two dimensional data smoothing and least-square gradient estimate
Savitsky-Golay filters can also be used to smooth two dimensional data affected by noise. The algorithm is exactly the same as for the one dimensional case, only the math is a bit more tricky. The basic algorithm is as follow:
- for each point of the two dimensional matrix extract a sub-matrix, centered at that point and with a size equal to an odd number "window_size".
- for this sub-matrix compute a least-square fit of a polynomial surface, defined as
p(x,y) = a0 + a1*x + a2*y + a3*x2 + a4*y2 + a5*x*y + ... . Note that x and y are equal to zero at the central point.
- replace the initial central point with the value computed with the fit.
Note that because the fit coefficients are linear with respect to the data spacing, they can pre-computed for efficiency. Moreover, it is important to appropriately pad the borders of the data, with a mirror image of the data itself, so that the evaluation of the fit at the borders of the data can happen smoothly.
Here is the code for two dimensional filtering.

Gradient of a two-dimensional function
Since we have computed the best fitting interpolating polynomial surface it is easy to compute its gradient. This method of computing the gradient of a two dimensional function is quite robust, and partially hides the noise in the data, which strongly affects the differentiation operation. The maximum order of the derivative that can be computed obviously depends on the order of the polynomial used in the fitting.
The code provided above have an option derivative, which as of now allows to compute the first derivative of the 2D data. It can be "row"or "column", indicating the direction of the derivative, or "both", which returns the gradient. | http://wiki.scipy.org/Cookbook/SavitzkyGolay | CC-MAIN-2013-48 | refinedweb | 1,803 | 58.08 |
Hi
Ive been experimenting with "mixed world" IJ2 and IJ1 commands. Its working really well but Ive been having some memory build up issues which eventually lead to "Out of Memory" errors if the command is run on a large number of datasets. I think Ive narrowed the problem down to the conversion from IJ2 datasets to IJ1 ImagePlus objects. The following groovy script should hopefully reproduce this problem, its much more obvious if run on a largeish multidimensional dataset.
Any help or advice would be much appreciated.
Thank you
Jeremy
// @ImageJ ij
// @Dataset currentData
import net.imagej.legacy.LegacyService;
import ij.ImagePlus;
import ij.IJ;
import java.lang.System;
// create legacy service for conversion between IJ and IJ2 classes
LegacyService legacy = ij.get(LegacyService.class);
// run conversion a few times to demonstrate memory build up
for (int i = 0; i < 25; i++) {
println(i);
// convert to float, this makes the issue more obvious
dataFloat = ij.op().run("convert.float32", currentData);
// convert to IJ1 ImagePlus
imp = legacy.getImageMap().registerDataset(dataFloat);
}
// My attempt to clean up
dataFloat = null;
imp = null;
legacy = null;
System.gc();
Hi Jeremy,
I can reproduce the issue that you are describing on my machine.
Could you try to not use the LegacyService directly but use a UIService instead? Does the following Groovy script still result in the described memory error?
LegacyService
UIService
// @UIService uiService
// @OpService opService
// @Dataset currentData
import net.imagej.legacy.LegacyService;
import ij.ImagePlus;
import ij.IJ;
import java.lang.System;
// run conversion a few times to demonstrate memory build up
for (int i = 0; i < 25; i++) {
println(i);
// convert to float, this makes the issue more obvious
dataFloat = opService.run("convert.float32", currentData);
uiService.show("test", dataFloat);
}
// My attempt to clean up
dataFloat = null;
imp = null;
legacy = null;
System.gc();
Best,Stefan
Hi Stefan
Thank you for the response, its good to know the issue is reproducible.
Your script dosnt result in memory errors however the problem is I dont want to display the data which I think it what the UIService offers? I would like to use various ops commands and then retrieve an ij.ImagePlus object which can be used for IJ1 functionality.
BestJeremy
For now, you could use ImgLib2's ImageJFunctions.wrap(RandomAccessibleInterval<T> img, String title). Although I will admit that this might not be best practice.
ImageJFunctions.wrap(RandomAccessibleInterval<T> img, String title)
Maybe @imagejan is aware of a better way?
Great that seems to work with no memory build up.
Thank you very much.
Thanks for the report, @jpike.
It is definitely unfortunate that the LegacyService causes this issue for you. One of my goals is to eliminate any need to use ImageJFunctions directly.
ImageJFunctions
I guess we should file an issue in imagej-legacy about this. Otherwise I will probably forget, and this thread will fade into the background.

#include <sys/rman.h>_FIRSTSHARE 0x0020 /* first in sharing list */ #define RF_PREFETCHABLE 0x0040 /* resource is prefetchable */ #define RF_UNMAPPED 0x0100 /* don't map resource when activating */
Bits 15:10 of the flag register. The rm_start and rm_end fields may be set to limit the range of acceptable resource addresses. If these fields are not set, rman_init() will initialize them to allow the entire range of resource addresses. It also initializes any mutexes associated with the structure. If rman_init() fails to initialize the mutex, it will return ENOMEM; otherwise it will return 0 and rm will be initialized.. If any part of the region falls outside of the valid address range for rm, it will return EINVAL. ENOMEM will be returned when rman_manage_region() failed to allocate memory for the region.
The rman_init_from_resource() function is a wrapper routine to create a resource manager backed by an existing resource. It initializes rm using rman_init() and then adds a region to rm corresponding to the address range allocated to r via rman_manage_region().
The rman_first_free_region() and rman_last_free_region() functions can be used to query a resource manager for its first (or last) unallocated region. If rm contains no free region, these functions will return ENOENT. Otherwise, *start and *end are set to the bounds of the free region and zero is returned. a boundary restriction and required aligment, and the code will attempt to find a free segment which fits. The start argument is the lowest acceptable starting value of the resource. The end argument is the highest acceptable ending value of the resource. Therefore, start, No, +, Fa, count, No, -, 1 must be [<=] end for any allocation to happen. The aligment requirement (if any) is specified in flags. The bound argument may be set to specify a boundary restriction such that an allocated region may cross an address that is a multiple of the boundary. The bound argument must be a power of two. It may be set to zero to specify no boundary restriction. A shared segment will be allocated if the RF_SHAREABLE flag is set, otherwise an exclusive bound argument.
The rman_make_alignment_flags() function returns the flag mask corresponding to the desired alignment size. This should be used when calling rman_reserve_resource_bound().
The rman_is_region_manager() function returns true if the allocated resource r was allocated from rm. Otherwise, it returns false.
The rman_adjust_resource() function is used to adjust the reserved address range of an allocated resource to reserve start through end. It can be used to grow or shrink one or both ends of the resource range. The current implementation does not support entirely relocating the resource and will fail with EINVAL if the new resource range does not overlap the old resource range. If either end of the resource range grows and the new resource range would conflict with another allocated resource, the function will fail with EBUSY. The rman_adjust_resource() function does not support adjusting the resource range for shared resources and will fail such attempts with EINVAL. Upon success, the resource r will have a start address of start and an end address of end and the function will return zero. Note that none of the constraints of the original allocation request such as alignment or boundary restrictions are checked by rman_adjust_resource(). It is the caller's responsibility to enforce any such requirements._mapping() function is used to associate a resource mapping with a resource r. The mapping must cover the entire resource. Setting a mapping sets the associated bus_space(9) handle and tag for r as well as the kernel virtual address if the mapping contains one. These individual values can be retrieved via rman_get_bushandle(), rman_get_bustag(), and rman_get_virtual().
The rman_get_mapping() function can be used to retrieve the associated resource mapping once set.
The rman_set_rid() function associates a resource identifier with a resource r. The rman_get_rid() function retrieves this RID.
The rman_get_device() function returns a pointer to the device which reserved the resource r.

Update, July 25, 2015: I included some new plots suggested by my colleague Ariel Rokem. Scroll to the end!
Last year I wrote a blog post examining trends in Seattle bicycling and how they relate to weather, daylight, day of the week, and other factors. supervised machine learning approach for data modeling, this post will examine the data using an unsupervised learning approach for data exploration.
Along the way, we'll see some examples of importing, transforming, visualizing, and analyzing data in the Python language, using mostly Pandas, Matplotlib, and Scikit-learn. We will also see some real-world examples of the use of unsupervised machine learning algorithms, such as Principal Component Analysis and Gaussian Mixture Models, in exploring and extracting meaning from data.
To spoil the punchline (and perhaps whet your appetite) what we will find is that from analysis of bicycle counts alone, we can make some definite statements about the aggregate work habits of Seattleites who commute by bicycle.
The data we will use here are the hourly bicycle counts on Seattle's Fremont Bridge.
These data come from an automated bicycle counter, installed in late 2012, which has inductive sensors under the sidewalks on either side of the bridge.
The daily or hourly bicycle counts can be downloaded from; here is the direct link to the hourly dataset.
To download the data directly, you can uncomment the following
curl command:
# !curl -o FremontBridge.csv
import pandas as pd data = pd.read_csv('FremontBridge.csv', index_col='Date', parse_dates=True) data.head()
We'll do some quick data cleaning: we'll rename the columns to the shorter "West" and "East", set any missing values to zero, and add a "Total" column:
data.columns = ['West', 'East'] data.fillna(0, inplace=True) data['Total'] = data.eval('East + West')
We can get a better idea of the dataset as a whole through a simple visualization; for example, we can resample the data to see the weekly trend in trips over the nearly three-year period:
# first some standard imports %matplotlib inline import matplotlib.pyplot as plt import seaborn; seaborn.set() # plot styling import numpy as np data.resample('W', how='sum').plot() plt.ylabel('weekly trips');
The counts show both a strong seasonal variation, as well as a local structure that can be partially accounted for by temperature, time of year, precipitation, and other factors.
From here, we could do a variety of other visualizations based on our intuition about what might affect bicycle counts. For example, we could look at the effect of the days of the week, the effect of the weather, and other factors that I explored previously. But we could also proceed by letting the dataset speak for itself, and use unsupervised machine learning techniques (that is, machine learning without reference to data labels) to learn what the data have to tell us.
We will consider each day in the dataset as its own separate entity (or sample, in usual machine learning parlance). For each day, we have 48 observations: two observations (east and west sidewalk sensors) for each of the 24 hour-long periods. By examining the days in light of these observations and doing some careful analysis, we should be able to extract meaningful quantitative statements from the data themselves, without the need to lean on any other assumptions.
The first step in this approach is to transform our data; essentially we will want a two-dimensional matrix, where each row of the matrix corresponds to a day, and each column of the matrix corresponds to one of the 48 observations.
We can arrange the data this way using the
pivot_table() function in Pandas.
We want the "East" and "West" column values, indexed by date, and separated by hour of the day.
Any missing values we will fill with zero:
pivoted = data.pivot_table(['East', 'West'], index=data.index.date, columns=data.index.hour, fill_value=0) pivoted.head()
5 rows × 48 columns
Next we extract the raw values and put them in a matrix:
X = pivoted.values X.shape
(1001, 48)
Our data consists of just over 1000 days, each with the aforementioned 48 measurements.
We can think of this data now as representing 1001 distinct objects which live in a 48-dimensional space: the value of each dimension is the number of bicycle trips measured on a particular side of the bridge at a particular hour. Visualizing 48-dimensional data is quite difficult, so instead we will use a standard dimensionality reduction technique to project this to a more manageable size.
The technique we'll use is Principal Component Analysis (PCA), a fast linear projection which rotates the data such that the projection preserves the maximum variance. We can ask for components preserving 90% of the variance as follows:
from sklearn.decomposition import PCA Xpca = PCA(0.9).fit_transform(X) Xpca.shape
(1001, 2)
The output has two dimensions, which means that these two projected components describe at least 90% of the total variance in the dataset. While 48-dimensional data is difficult to plot, we certainly know how to plot two-dimensional data: we'll do a simple scatter plot, and for reference we'll color each point according to the total number of trips taken that day:
total_trips = X.sum(1) plt.scatter(Xpca[:, 0], Xpca[:, 1], c=total_trips, cmap='cubehelix') plt.colorbar(label='total trips');
We see that the days lie in two quite distinct groups, and that the total number of trips increases along the length of each projected cluster. Further, the two groups begin to be less distinguishable when the number of trips during the day is very small.
I find this extremely interesting: from the raw data, we can determine that there are basically two primary types of days for Seattle bicyclists. Let's model these clusters and try to figure out what these types-of-day are.
When you have groups of data you'd like to automatically separate, but no previously-determined labels for the groups, the type of algorithm you are looking at is a clustering algorithm. There are a number of clustering algorithms out there, but for nicely-defined oval-shaped blobs like we see above, Gaussian Mixture Models are a very good choice. We can compute the Gaussian Mixture Model of the data using, again, scikit-learn, and quickly plot the predicted labels for the points:
from sklearn.mixture import GMM gmm = GMM(2, covariance_type='full', random_state=0) gmm.fit(Xpca) cluster_label = gmm.predict(Xpca) plt.scatter(Xpca[:, 0], Xpca[:, 1], c=cluster_label);
This clustering seems to have done the job, and separated the two groups we are interested in. Let's join these inferred cluster labels to the initial dataset:
pivoted['Cluster'] = cluster_label data = data.join(pivoted['Cluster'], on=data.index.date) data.head()
Now we can find the average trend by cluster and time using a GroupBy within this updated dataset
by_hour = data.groupby(['Cluster', data.index.time]).mean() by_hour.head()
Finally, we can plot the average hourly trend among the days within each cluster:
fig, ax = plt.subplots(1, 2, figsize=(14, 5)) hourly_ticks = 4 * 60 * 60 * np.arange(6) for i in range(2): by_hour.ix[i].plot(ax=ax[i], xticks=hourly_ticks) ax[i].set_title('Cluster {0}'.format(i)) ax[i].set_ylabel('average hourly trips')
These plots give us some insight into the interpretation of the two clusters: the first cluster shows a sharp bimodal traffic pattern, while the second shows a wide unimodal pattern.
In the bimodal cluster, we see a peak around 8:00am which is dominated by cyclists on the west sidewalk, and another peak around 5:00pm which is dominated by cyclists on the east sidewalk. This is very clearly a commute pattern, with the majority of cyclists riding toward downtown Seattle in the morning, and away from downtown Seattle in the evening.
In the unimodal cluster, we see fairly steady traffic in each direction beginning early in the morning and going until late at night, with a peak around 2:00 in the afternoon. This is very clearly a recreational pattern of use, with people out riding through the entire day.
I find this is fascinating: from simple unsupervised dimensionality reduction and clustering, we've discovered two distinct classes of days in the data, and found that these classes have very intuitive explanations.
Let's go one step deeper and figure out what we can learn about people (well, bicycle commuters) in Seattle from just this hourly commute data. As a rough approximation, you might guess that these two classes of data might be largely reflective of workdays in the first cluster, and non-work days in the second. We can check this intuition by re-plotting our projected data, except labeling them by day of the week:
dayofweek = pd.to_datetime(pivoted.index).dayofweek plt.scatter(Xpca[:, 0], Xpca[:, 1], c=dayofweek, cmap=plt.cm.get_cmap('jet', 7)) cb = plt.colorbar(ticks=range(7)) cb.set_ticklabels(['Mon', 'Tues', 'Wed', 'Thurs', 'Fri', 'Sat', 'Sun']) plt.clim(-0.5, 6.5);
We see that the weekday/weekend intuition holds, but only to a point: in particular, it is clear that there are a handful of weekdays which follow the typical weekend pattern! Further, it's interesting to note that Fridays tend to be pulled closer to weekend days in this plot, though as a whole they still fall solidly in the work-day cluster.
Let's take a closer look at the "special" weekdays that fall in the "wrong" cluster. We start by constructing a dataset listing the cluster id and the day of the week for each of the dates in our dataset:
results = pd.DataFrame({'cluster': cluster_label, 'is_weekend': (dayofweek > 4), 'weekday': pivoted.index.map(lambda x: x.strftime('%a'))}, index=pivoted.index) results.head()
First, let's see how many weekend days fall in the first, commute-oriented cluster
weekend_workdays = results.query('cluster == 0 and is_weekend') len(weekend_workdays)
0
zero! Apparently, there is not a single weekend during the year where Seattle cyclists as a whole decide to go to work.
Similarly, we can see how many weekdays fall in the second, recreation-oriented cluster:
midweek_holidays = results.query('cluster == 1 and not is_weekend') len(midweek_holidays)
23
There were 23 weekdays over the past several years in which Seattle cyclists as a whole did not go to work. To label these, let's load the US Federal holiday calendar available in Pandas:
from pandas.tseries.holiday import USFederalHolidayCalendar cal = USFederalHolidayCalendar() holidays = cal.holidays('2012', '2016', return_name=True) holidays.head()
2012-01-02 New Years Day 2012-01-16 Dr. Martin Luther King Jr. 2012-02-20 Presidents Day 2012-05-28 MemorialDay 2012-07-04 July 4th dtype: object
Just for completeness, we will add to the list the day before and day after each of these holidays:
holidays_all = pd.concat([holidays, "Day Before " + holidays.shift(-1, 'D'), "Day After " + holidays.shift(1, 'D')]) holidays_all = holidays_all.sort_index() holidays_all.head()
2012-01-01 Day Before New Years Day 2012-01-02 New Years Day 2012-01-03 Day After New Years Day 2012-01-15 Day Before Dr. Martin Luther King Jr. 2012-01-16 Dr. Martin Luther King Jr. dtype: object
Note that these are observed holidays, which is why New Years Day 2012 falls on January 2nd. With this ready to go, we can compute the complete list of non-weekend days on which Seattle bicycle commuters as a whole chose to stay home from work:
holidays_all.name = 'name' # required for join joined = midweek_holidays.join(holidays_all) set(joined['name'])
{'Christmas', 'Day After Christmas', 'Day After Thanksgiving', 'Day Before Christmas', 'July 4th', 'Labor Day', 'MemorialDay', 'New Years Day', 'Thanksgiving'}
On the other side of things, here are the Federally recognized holidays where Seattle bicycle commuters chose to go to work anyway:
set(holidays) - set(joined.name)
{'Columbus Day', 'Dr. Martin Luther King Jr.', 'Presidents Day', 'Veterans Day'}
A colleague of mine, Ariel Rokem, saw the first version of this post and noticed something interesting. For the most part, Fridays tend to lie on the upper side of the weekday cluster, closer in this parameter space to the typical weekend pattern. This pattern holds nearly universally for Fridays, all except for three strange outliers which lie far on the other side of the cluster.
We can see these more clearly if we highlight the Friday points in the plot:
fridays = (dayofweek == 4) plt.scatter(Xpca[:, 0], Xpca[:, 1], c='gray', alpha=0.2) plt.scatter(Xpca[fridays, 0], Xpca[fridays, 1], c='yellow');
The yellow points in the bottom-left of the plot are unique – they're far different than other Fridays, and they even stand-out in comparison to the other work days! Let's see what they represent:
weird_fridays = pivoted.index[fridays & (Xpca[:, 0] < -600)] weird_fridays
Index([2013-05-17, 2014-05-16, 2015-05-15], dtype='object')
All three of these outlying Fridays fall in the middle of May. Curious!
Let's quickly visualize the daily stats for these, along with the mean trend over all days. We can arrange the data this way with a pivot table operation:
all_days = data.pivot_table('Total', index=data.index.time, columns=data.index.date) all_days.loc[:, weird_fridays].plot(); all_days.mean(1).plot(color='gray', lw=5, alpha=0.3, xticks=hourly_ticks);
Apparently these three strange Fridays are days with extreme amounts of bicycle commuting. But what makes them so special?
After some poking-around on the internet, the answer becomes clear: we've discovered Seattle's annual bike to work day. Mystery solved!
We have seen here that by taking a close look at raw bicycle counts and using some basic visualization and unsupervised machine learning, we can make some very definite statements about the overall work habits of people in Seattle who bicycle to work across the Fremont bridge. In summary, this is what we have learned:

higher level and solve the fundamental problems of software
development, algorithm reuse, and binary interoperability.
Actually, templates are certainly the most interesting and novative
aspect of C++.
The fact that it is given more work than other 'problems' is proof
that more people are simply more interested with it.
I just finished watching a Google tech talk presentation on concepts
in the upcoming C++0x standard and it left me wondering.
Google is not really known for its modern usage of C++. To me it seems
they use it "the old way".
The concepts
seem like a good idea, but it does concern me that such metaphore
specific notions are making it into the C++ language ahead of perhaps
more basic and useful features.
Concepts, technically, aren't really needed. Similar functionality can
already be achieved by the language as it is.
The whole idea of concepts is to allow simpler code and simpler error
messages.
The metaphore that i refer to is that off iterators. Without
iterators, STL would not be what it is. Both STL and Boost are
libraries which have been designed around a single idea, the use of C+
+ operators to provide non type specific generic algorithms and
containers.
I certainly wouldn't say that. Especially for boost, which contains
various different things.
The aim STL, as it names says, is to provide templates for data
structures and related algorithms.
I don't see the relation with operators.
"non type specific" is a weird expression, and makes me thing you
misunderstand templates.
With templates, everything is type specific, it's just that it can be
generated for any type. It's not obfuscation.
But it means that the algorithms and containers are
restricted to things which behave like pointers.
Huh? I fail to see the relation.
Are you talking about the fact that the iterator design is purposedly
modeled after pointers?
That's just a question of style, it could have used next(), etc.
C++ operators are
convinient becuase they dont require you to specify types in the
definition of your code
You always need to specify the type of the variable in C++.
(There will be type inference in C++0x though)
and they support primitive types which you
cannot do directly with interfaces, but it isnt very OO
Templates are just what they are, templates. A calibre of a class of
function, that you can instantiate with types or integers to generate
the given class or function.
They have no relation with OO. Which is a good thing, by the way. With
OO and subtyping polymorphism the real type of objects is not known
until runtime, while templates work at compile-time and can use
inference to instantiate themselves in the case of template functions.
and no, i dont
buy the notion of "parametric polymorphism".
It's not whether you buy it or not.
It's a notion that exists, and is heavily demonstrated by statically
typed functional languages such as ML.
Templates offer that kind of functionality for C++.
The boundary between the opaque and the visible for the user only
occurs when they dereference an iterator, at this point the user must
know the underlying type and the generic metaphore falls away to
expose the details of the implementation.
If you don't know the types of your variables, maybe you shouldn't use
them in the first place.
The type of your iterator contains all the necessary information to
know the type of the derefenced element.
This is a clever workaround
It's not especially new or clever.
and it has allowed libraries like Boost
and STL to flourish, but it is not the only way, and it has its
drawbacks.
The only drawback it that, since it happens at compile-time, it can't
be dynamic.
For instance, using the STL metaphore it is not possible
to create a function which takes only an iterator of integers because
there is no such thing as an iterator of integers, the underlying type
is hidden.
That's absolutely false.
The iterator type contains the information of the type it iterates.
While such an information wouldn't be in the type using an OO design,
it is with templates.
Writing such a function can be done with SFINAE, which becomes easy
using tools from boost :
template<typename It>
typename enable_if<
is_same<It::value_type, int>,
void>::type
some_function(It it);
Iterators deal only with operators, not with types or
interfaces. Its more like passing around macros, with all of the
details being obscured.
There is nothing obscure.
All information is in the type.
So the STL metaphore necessarily does not integrate well with the
underlying C++ type system
It integrates very well. So well that people are still amazed by
things you can do with it.
and cannot be constrained by overloading
They can, using SFINAE.
or inheritance.
Templates apply on types. Inheritance is a special propriety of a
specific category of types.
They're of course not related.
I think we should not forget that C++ was an object
oriented language well before generic programming came about
That would be a very good thing to forget.
The OO idiom in C++ is certainly not its good side.
Generations of developers thought C++ was an OO language, but they
were simply coding in C with Classes. That's very far from the
functionality modern C++ gives.
and
perhaps some of the ideas which generic programming brings with it are
better suited to functional languages.
There is nothing especially functional in genericity.
And C++ can handle the functional idiom quite well.
Generic code is unfortunately opaque, and whilst it can be amazingly
useful, there is a high price to pay in terms or readability and
debugability.
It's not more opaque and non generic code.
Actually, it is often clearer, since it is generic and not specific to
some kind of type.
So before we take library specific ideas like begin() and end() and
start building for loops and concept maps around them and adding
support for requirements in generic code, can we pause and considder
the alternatives ?
Looks like you don't understand concept maps.
What about ensuring that C++ templates can be overloaded by interfaces
rather than just concrete types ?
template<typename Kind>
class Compare
{
public:
int Compare(Kind left, Kind right) {return left-right;}
}
Here, you could just write your comparison as left < right, and if
operator<(decltype(left), decltype(right)) is not found, you get a
compile-time error.
template<typename Kind>
class Compare<Comparable Kind>
{
public:
int Compare(Kind left, Kind right) {return left.Compare(right);}
}
Thats a pretty useful feature when your doing generic programming
That's concepts.
They're doable using library techniques as of today, and are being
included in the next standard to be simpler.
that
does not use the STL or Boost metaphore
It *is* the STL metaphore.
For example, to instantiate std::set with a type, that type must
satisfy the requirement of comparable.
and it integrates tightly with
the more OO aspects of C++, overloading and inheritance.
I fail to see the OO integration.
And how about standardising the representation of function pointers so
that we can write better even handling and callbacks.
I don't see how standardizing the representation of function pointers
would help for callbacks.
What about
closures and coroutines ? Why do these ideas have to remain
"undefined" whilst we focus on much more esoteric problems.
Closures can certainly be very well done in C++, thanks to
overloading. It's called functors.
This is already highly used by the STL, by the way. Be it to indicate
how comparison is to be done or what code to apply with an algorithm
(for_each, transform, etc.)
Functors are usually used through templates, but you can also use them
through subtyping polymorphism, in case you need a single type (to
store the thing, eventually). Of course, the later introduces some
overhead.
For that there is an utility in boost and TR1 to unify all functors
with the same signature to a single type, it's called boost::function.
It could be implemented like this, but actually it uses other tricks
for efficiency.
Here is how for a function taking no argument. For other cases, the
template will have to be "overloaded". Usage of variadic templates (a
new C++0x feature) could also be considered.
template<typename R>
struct base
{
virtual R operator()() = 0;
};
template<typename R, typename F>
struct derived : base<R>
{
derived(const F& f)
{
f_ = f;
}
R operator()()
{
return f_();
}
F f_;
};
template<typename R>
class function
{
public:
template<typename F>
function(const F& f)
{
p_ = new derived<R, F>(f);
}
~function()
{
delete p_;
}
R operator()()
{
return (*p_)();
}
/* additional stuff */
private:
base<R>* p_;
};
Notice how templates and inheritance can be used together to create
that kind of generic, yet runtime-oriented, component.
For every generic programming feature in the C++0x standard, i fear
there will be 10 far more imporant and far more fundamental non
generic features which will be missed. And for all this we have to
wait till the end of the decade. Whoopy do !
Templates are one of the key features of C++, more important than
subtyping polymorphism, which can simply be done by hand with function
pointers anyway.
The only point where templates don't integrate well is with
virtuality, because that would mean the vtable can't be generated
until link-time. That's kinda problematic given the translation model
of C++.
That's too bad actually, that would allow very interesting things.
If your interested in some concrete examples of the alternative
generic programming metaphores which are out there, check out the
structure's namespace from the C++ framework that i recently released
called Reason.
When reading your work it seems your definition of OO varies.
I was assuming you meant subtyping polymorphism, but actually
sometimes it seems you're just talking about the idea of object based
programming, grouping state data in objects and attaching member
functions to them.
So basically, your reproach that STL is not OO is based on the fact
that to advance an iterator, you have to do ++it and not it.next() ?
It frustrates me that so much of the code that we write has to be
thrown away, but atleast i can take pride in the fact that the code i
write is readable and understandable. It can always be ported to
another language when C++ eventually digs a hole so deep we cant climb
out :(
That's not gonna happen, only C++ has this awesome feature called
templates. ;)

For filesystem management and template caching, add the TemplateLookup class.

Mako: 1.10 ms Kid: 14.54 ms
Standard template features
control structures constructed from real Python code (i.e. loops, conditionals)
straight Python blocks, inline or at the module-level
Callable blocks
can access variables from their enclosing scope as well as the template's request context
can be nested arbitrarily
can specify regular Python argument signatures
outer-level callable blocks can be called by other templates or controller code (i.e. "method call")
calls to functions can define any number of sub-blocks of content which are accessible to the called function (i.e. "component-call-with-content"). This is the basis for nestable custom tags.
Inheritance
supports "multi-zoned" inheritance - define any number of areas in the base template to be overridden.
supports "chaining" style inheritance - call next.body() to call the "inner" content.
the full inheritance hierarchy is navigable in both directions (i.e. parent and child) from anywhere in the chain.
inheritance is dynamic ! Specify a function instead of a filename to calculate inheritance on the fly for every request.
Examples¶
Basic Usage
from mako.template import Template mytemplate = Template("hello world!") print mytemplate.render()="openerp")
Using File-based Templates
A Tempalte can also load its template source code from a file, using the filename keyword argument:
from mako.template import Template mytemplate = Template(filename='/test.html') print mytemplate.render()
Using TemplateLook=['']) mytemplate = Tempalte('<% include Hello!',lookup=mylookup)
Above, we created a textual template which includes the file "header.txt".
In order for it to have somewhere to look for "header.txt", we passed a TemplateLookup object to it, which will search in the current directory for the file "header.txt".
Syntax¶
Expression Substitution
The simplest expression is just a variable substitution.
The syntax for this is the ${} construct, which is inspired by Perl, Genshi, JSP EL, and others:
${x}
${5%5}
${7*2}
${pow(x,2) + pow(y,2)}
Controller Structures
Conditionals(i.e if/else)
loops(for and while)
as well as try/except
control structures are written using the % marker followed by a regular Python control expression, and are “closed” by using another % marker with the tag “end<name>“, where “<name>” is the keyword of the expression:
% if user_name == 'openerp': valid user % endif % if a > 1: a is positive number % elif a == 0: a is 0 % else: a is negative number % endif <table> % for a in [1,2,3,4,5]: <tr> <td> ${a} </td> </tr> % endfor </table>
Python Blocks
Any arbitrary block of python can be dropped in using the <% %> tags:
<% a = {'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5} b = a.values() %> % for x in b: ${x} % endfor
Module-level Blocks
A variant on <% %> is the module-level code block, denoted by <%! %>.
Code within these tags is executed at the module level of the template, and not within the rendering function of the template.
<%! import cherrypy def get_user_from_session(): return cherrypy.session['current_user'] %>
Therefore, this code does not have access to the template’s context and is only executed when the template is loaded into memory (which can be only once per application, or more, depending on the runtime environment).
Mako Tags
<%page>
This tag defines general characteristics of the template, including caching arguments, and optional lists of arguments which the template expects when invoked.
Also defines caching characteristics.
<%page <%page
<%include>
just accepts a file argument and calls in the rendered result of that file:
Also accepts arguments which are available as <%page> arguments in the receiving template:
<%include Welcome to OpenERP <%include <%include
<%inherit>
Inherit allows templates to arrange themselves in inheritance chains.
When using the %inherit tag, control is passed to the topmost inherited template first, which then decides how to handle calling areas of content from its inheriting templates.
<%inherit
<%def>
The %def tag defines a Python function which contains a set of content, that can be called at some other point in the template.).
<%def this is function ${x} <%def>
<%namespace>
%namespace is Mako’s equivalent of Python’s import statement.
It allows access to all the rendering functions and metadata of other template files, plain Python modules, as well as locally defined “packages” of functions.
<%namespace
<%doc>
handles multiline comments:
<%doc> Multi line comments Using doc tag </%doc>

The search pattern can be a simple character or a substring or it may be a complex string or expression that defines a particular pattern to be searched in the string.
Further, the pattern may have to match one or more times to the string.

What You Will Learn:
- Regular Expression: Why We Need It
- Conclusion
Regular Expression: Why We Need It
A regular expression is mainly used to search for a pattern in a string. Why do we search for a pattern in a string? We might want to find a particular pattern in a string and then manipulate it or edit it.
So in a computer application, we may have a continuous requirement of manipulating various patterns. Hence, we always require regex to facilitate searching for the pattern.
Now given a pattern to search for, how exactly does the regex works?
When we analyze and alter the text using a regex, we say that ‘we have applied regex to the string or text’. What we do is we apply the pattern to the text in a ‘left to right’ direction and the source string is matched with the pattern.
For example, consider a string “ababababab”. Let’s assume that a regex ‘aba’ is defined. So now we have to apply this regex to the string. Applying the regex from left to right, the regex will match the string “aba_aba___”, at two places.
Thus once a source character is used in a match, we cannot reuse it. Thus after finding the first match aba, the third character ‘a’ was not reused.
java.util.regex
Java language does not provide any built-in class for regex. But we can work with regular expressions by importing the “java.util.regex” package.
The package java.util.regex provides one interface and three classes as shown below:
Pattern Class: A pattern class represents the compiled regex. The Pattern class does not have any public constructors but it provides static compile () methods that return Pattern objects and can be used to create a pattern.
Matcher Class: The Matcher class object matches the regex pattern to the string. Like Pattern class, this class also does not provide any public constructors. It provides the matcher () method that returns a Matcher object.
PatternSyntaxException: This class defines an unchecked exception. An object of type PatternSyntaxException returns an unchecked exception indicating a syntax error in regex pattern.
MatchResult Interface: The MatchResult interface determines the regex pattern matching result.
Java Regex Example
Let’s implement a simple example of regex in Java. In the below program we have a simple string as a pattern and then we match it to a string. The output prints the start and end position in the string where the pattern is found.
import java.util.regex.Matcher; import java.util.regex.Pattern; public class Main { public static void main(String args[]) { //define a pattern to be searched Pattern pattern = Pattern.compile("Help."); // Search above pattern in "softwareTestingHelp.com" Matcher m = pattern.matcher("softwareTestingHelp.com"); // print the start and end position of the pattern found while (m.find()) System.out.println("Pattern found from position " + m.start() + " to " + (m.end()-1)); } }
Output:
Pattern found from 15 to 19
Regex Matcher In Java
The matcher class implements the MatchResult interface. Matcher acts as a regex engine and is used to perform the exact matching of a character sequence.
Given below are the common methods of the Matcher class. It has more methods but we have listed only the important methods below.
Regular Expression Implementation Example
Let’s see an example of the usage of some of these methods.
import java.util.regex.Matcher; import java.util.regex.Pattern; public class MatcherDemo { public static void main(String[] args) { String inputString = "She sells sea shells on the sea shore with shells"; //obtain a Pattern object Pattern pattern = Pattern.compile("shells"); // obtain a matcher object System.out.println("input string: " + inputString); Matcher matcher = pattern.matcher(inputString); inputString = matcher.replaceFirst("pearls"); System.out.println("\nreplaceFirst method:" + inputString); //use replaceAll method to replace all occurrences of pattern inputString = matcher.replaceAll("pearls"); System.out.println("\nreplaceAll method:" + inputString); } }
Output:
input string: She sells sea shells on the sea shore with shells
replaceFirst method:She sells sea pearls on the sea shore with shells
replaceAll method:She sells sea pearls on the sea shore with pearls
Regex Pattern Class In Java
Pattern class defines the pattern for the regex engine which can then be used to match with the input string.
The following table shows the methods provided by the Pattern class that is commonly used.
The below example uses some of the above methods of Pattern class.
import java.util.regex.*; public class Main { public static void main(String[] args) { // define a REGEX String String REGEX = "Test"; // string to be searched for given pattern String actualString = "Welcome to SoftwareTestingHelp portal"; // generate a pattern for given regex using compile method Pattern pattern = Pattern.compile(REGEX); // set limit to 2 int limit = 2; // use split method to split the string String[] array = pattern.split(actualString, limit); // print the generated array for (int i = 0; i < array.length; i++) { System.out.println("array[" + i + "]=" + array[i]); } } }
Output:
array[0]=Welcome to Software
array[1]=ingHelp portal
In the above program, we use the compile method to generate a pattern. Then we split the input string about this pattern and read it into an array. Finally, we display the array that was generated as a result of splitting the input string.
Regex String Matches Method
We have seen the String.Contains () method in our string tutorials. This method returns a boolean value true or false depending on if the string contains a specified character in it or not.
Similarly, we have a method “matches ()” to check if the string matches with a regular expression or regex. If the string matches the specified regex then a true value is returned or else false is returned.
The general syntax of the matches () method:
public boolean matches (String regex)
If the regex specified is not valid, then the “PatternSyntaxException” is thrown.
Let’s implement a program to demonstrate the usage of the matches () method.
public class MatchesExample{ public static void main(String args[]){ String str = new String("Java Series Tutorials"); System.out.println("Input String: " + str); //use matches () method to check if particular regex matches to the given input System.out.print("Regex: (.*)Java(.*) matches string? " ); System.out.println(str.matches("(.*)Java(.*)")); System.out.print("Regex: (.*)Series(.*) matches string? " ); System.out.println(str.matches("(.*)Series(.*)")); System.out.print("Regex: (.*)Series(.*) matches string? " ); System.out.println(str.matches("(.*)String(.*)")); System.out.print("Regex: (.*)Tutorials matches string? " ); System.out.println(str.matches("(.*)Tutorials")); } }
Output:
Input String: Java Series Tutorials
Regex: (.*)Java(.*) matches string? true
Regex: (.*)Series(.*) matches string? true
Regex: (.*)Series(.*) matches string? false
Regex: (.*)Tutorials matches string? true
We use lots of special characters and Metacharacters with regular expressions in Java. We also use many character classes for pattern matching. In this section, we will provide the tables containing character classes, Meta characters, and Quantifiers that can be used with regex.
Regex Character Classes
Regex Quantifiers
Quantifiers are used to specify the number of times the character will occur in the regex.
The following table shows the common regex quantifiers used in Java.
Regex Meta Characters
The Metacharacters in regex work as shorthand codes. These codes include whitespace and non-whitespace character along with other shortcodes.
The following table lists the regex Meta characters.
Given below is a Java program that uses the above special characters in the Regex.
import java.util.regex.*; public class RegexExample{ public static void main(String args[]){ // returns true if string exactly matches "Jim" System.out.print("Jim (jim):" + Pattern.matches("Jim", "jim")); // Returns true if the input string is Peter or peter System.out.println("\n[Pp]eter(Peter) :" + Pattern.matches("[Pp]eter", "Peter")); //true if string = abc System.out.println("\n.*abc.*(pqabcqp) :" + Pattern.matches(".*abc.*", "pqabcqp")); // true if string doesn't start with a digit System.out.println("\n^[^\\d].*(abc123):" + Pattern.matches("^[^\\d].*", "abc123")); // returns true if the string contains exact three letters System.out.println("\n[a-zA-Z][a-zA-Z][a-zA-Z] (aQz):" + Pattern.matches("[a-zA-Z][a-zA-Z][a-zA-Z]", "aQz")); System.out.println("\n[a-zA-Z][a-zA-Z][a-zA-Z], a10z" + Pattern.matches("[a-zA-Z][a-zA-Z][a-zA-Z], a10z", "a10z")); //input string length = 4 // true if the string contains 0 or more non-digits System.out.println("\n\\D*, abcde:" + Pattern.matches("\\D*", "abcde")); //True // true of line contains only word this ^-start of the line, $ - end of the line System.out.println("\n^This$, This is Java:" + Pattern.matches("^This$", "This is Java")); System.out.println("\n^This$, This:" + Pattern.matches("^This$, This", "This")); System.out.println("\n^This$, Is This Java?:" + Pattern.matches("^This$, Is This Java?", "Is This Java?")); } }
Output:
Jim (jim):false
[Pp]eter(Peter) :true
.*abc.*(pqabcqp) :true
^[^\d].*(abc123):true
[a-zA-Z][a-zA-Z][a-zA-Z] (aQz):true
[a-zA-Z][a-zA-Z][a-zA-Z], a10zfalse
\D*, abcde:true
^This$, This is Java:false
^This$, This:false
^This$, Is This Java?:false
In the above program, we have provided various regexes that are matched with the input string. Readers are advised to read the comments in the program for each regex to better understand the concept.
Regex Logical or (|) Operator
We can use the logical or (| operator) in regex that gives us the choice to select either operand of | operator. We can use this operator in a regex to give a choice of character or string. For example, if we want to match both the words, ‘test’ and ‘Test’, then we will include these words in logical or operator as Test|test.
Let’s see the following example to understand this operator.
import java.util.regex.Matcher; import java.util.regex.Pattern; public class RegexOR { public static void main(String[] args) { // Regex string to search for patterns Test or test String regex = "(Test|test)"; // Compiles the pattern and obtains the matcher object from input string. Pattern pattern = Pattern.compile(regex); String input = "Software Testing Help"; Matcher matcher = pattern.matcher(input); // print every match while (matcher.find()) { System.out.format("Text \"%s\" found at %d to %d.%n", matcher.group(), matcher.start(), matcher.end()); } //define another input string and obtain the matcher object input = "SoftwaretestingHelp"; matcher = pattern.matcher(input); // Print every match while (matcher.find()) { System.out.format("Text \"%s\" found at %d to %d.%n", matcher.group(), matcher.start(), matcher.end()); } } }
Output:
Text “Test” found at 9 to 13.
Text “test” found at 8 to 12.
In this program, we have provided the regex “(Test|test)”. Then first we give the input string as “Software Testing Help” and match the pattern. We see that the match is found and the position is printed.
Next, we give the input string as “SoftwaretestingHelp”. This time also the match is found. This is because the regex has used or operator and hence the pattern on either side of | operator is matched with the string.
We can also validate email id (address) with regex using java.util.regex.Pattern.matches () method. It matches the given email id with the regex and returns true if the email is valid.
The following program demonstrates the validation of email using regex.
public class EmailDemo { static boolean isValidemail(String email) { String regex = "^[\\w-_\\.+]*[\\w-_\\.]\\@([\\w]+\\.)+[\\w]+[\\w]$"; //regex to validate email. return email.matches(regex); //match email id with regex and return the value } public static void main(String[] args) { String email = "ssthva@gmail.com"; System.out.println("The Email ID is: " + email); System.out.println("Email ID valid? " + isValidemail(email)); email = "@sth@gmail.com"; System.out.println("The Email ID is: " + email); System.out.println("Email ID valid? " + isValidemail(email)); } }
Output:
The Email ID is: ssthva@gmail.com
The Email ID is: @sth@gmail.com
As we can see from the above output, the first email id is valid. The second id directly starts with @, and hence regex does not validate it. Hence it is an invalid id.
Frequently Asked Questions
Q #1) What is in a Regular Expression?
Answer: A Regular Expression commonly called regex is a pattern or a sequence of characters (normal or special or Meta characters) that is used to validate an input string.
Q #2) What is the significance of the Matcher class for a regular expression in Java?
Answer: The matcher class (java.util.regex.Matcher) acts as a regex engine. It performs the matching operations by interpreting the Pattern.
Q #3) What is the pattern in Java?
Answer: The package java.util.regex provides a Pattern class that is used to compile a regex into a pattern which is the standard representation for regex. This pattern is then used to validate strings by matching it with the pattern.
Q #4) What is B in a regular expression?
Answer: The B in regex is denoted as \b and is an anchor character that is used to match a position called word boundary. The start of the line is denoted with a caret (^) and the end of the line is denoted by a dollar ($) sign.
Q #5) Is pattern thread-safe Java?
Answer: Yes. Instances of the Pattern class are immutable and safe for use by multiple concurrent threads. But the matcher class instances are not thread-safe.
Conclusion.
We have also seen various special character classes and Metacharacters that we can use in the regex that give shorthand codes for pattern matching. We also explored email validation using regex.

Given a positive number N, write a function which returns sum of squares of numbers between 1 and N, i.e. 1^2 + 2^2 + ... + N^2.
Example: If N is 5, then return value should be 55 (1 + 4 + 9 + 16 + 25 = 55).
It is easy to produce sum o squares of a sequence by simply iterating through numbers 1 to N. Here is the function which does precisely that:
function Sum(n) begin sum = 0 for i = 1 to n sum = sum + i * i return sum end
This function runs in O(N) time and O(1) space. In order to improve the running time of the function, we need to find a definite form of the sum of squares. That is possible to do, and here is one of the ways to derive the simple form of the expression:
This derivation depends on the equation for calculating simple sum of the numbers 1 to N, which is explained in exercise Sum of First N Numbers. Now the function that runs in O(1) time and O(1) space looks like this:
function Sum(n) begin return n * (n + 1) * (2 * n + 1) / 6 end
Below is the full listing of a console application in C# which lets the user enter value N and then prints the sum of squares of the sequence.
using System; namespace SumOfSquares { public class Program { static int Sum(int n) { return n * (n + 1) * (2 * n + 1) 6; } static void Main(string[] args) { while (true) { Console.Write("Enter sequence length (zero to exit): "); int n = int.Parse(Console.ReadLine()); if (n <= 0) break; Console.WriteLine("Sum of the sequence is {0}\n", Sum(n)); } } } }
When application is run, it produces output like this:
Enter sequence length (zero to exit): 4 Sum of the sequence is 30 Enter sequence length (zero to exit): 5 Sum of the sequence is 55 Enter sequence length (zero to exit): 217 Sum of the sequence is 3429685. | http://codinghelmet.com/exercises/sum-of-squares-first-n | CC-MAIN-2019-04 | refinedweb | 335 | 59.47 |

Understand use of Pointers (*) in C and C++
Reading time: 35 minutes | Coding time: 10 minutes
We know that every instruction we give to the computer or every variable we define or every data we input must be stored in the memory of the computer so that it can be processed. This storage allocation is done in two ways:
1.Static
2.Dynamic
Static Allocation
In this, the amount of memory to be allocated is known beforehand and is reserved during compilation itself. Eg:
int arr[10] - defines an array of 10 elements and allocates 10 * sizeof(int) space.
Dynamic Allocation
In this, the amount of memory is not known beforehand and is allocated during run time, that is, when the program is actually running. Eg: In a Car Parking database of a shopping mall, we do not know the exact number of cars that will be visiting our mall throughout the day.
Pointers Facilitate this dynamic allocation
What is a Pointer
A pointer in C and C++ is a variable that contains a memory address which is usually the address/ location of another variable in the memory.
So, for example, if I say the pointer variable 'ptr' points to variable x, I mean that 'ptr' holds the memory location or the exact address where x is stored in the memory. The address is usually a hexadecimal address.
The pointers are one of the most unique, useful and strongest feature of C++. They allow us to directly access the memory of the computer.
Significance of Pointers in C++
- Pointers provide us a way in which the memory location can be directly accessed and thus be manipulated in the way we require.
- Pointers support C++'s dynamic allocation routines.
- Pointers can improve the efficiency of various inbuilt routines/functions.
Word of Caution
Although pointers provide us this powerful feature of accessing the memory, however, we must be careful while using them. Incorrect use of pointers can effect the program in inexplicable and complex ways.
Declaration and Intialisation of Pointers
Pointers are declared in pretty much the same way we declare variables in C++. However, in order to differentiate, we make use of the character
'*'.
General form of declaration-
type* pointer_name;
Description:
- 'type' indicates the data type to which this pointer will point to. Eg: an integer pointer can only point to int variable, a char pointer can only point to char variable and so on.
This means that pointers are data type specific.
An int pointer cannot point to a float variable and vice-versa. Same thing applies to all data types.
2. 'pointer_name' is any valid pointer name just like we name variables. All rules used for naming of idetifiers in C++ apply here as well.
Eg:
int* ipter;//creates an integer pointer
char* cpter;//creates a char pointer
float* fpter;//creates a float pointer
Initialisation of Pointers
A already stated, pointer variables hold memory addreses. But how do we make a pointer point to a variable, that is, how can we access its memory address to store it in the pointer variable?
This is where the unary operator & comes in.
Pointers revolve around the two operators:
* and
&
& - This is the operator which when placed before any variable returns its memory address which we can store in our pointer.
* - While this is used to declare a pointer also, however, when it is used with a pointer that has already been declared, it returns the value of the variable that is stored at the location to which the pointer is pointing to.
To understand the above two operators, consider the example-
Let us say we have a variable i, whose value = 25 and whose address = 10500(assume). Let us see what happens when we write the following lines of code-
int i = 25;
Normal variable declaration
int* iptr;
Declaration of pointer as discussed above. Note that here,
* is used for declaration purpose.
iptr = &i;
Here,
& operator is placed before i. Therefore, it will return the address of i which is 10500. This address gets stored in the pointer variable iptr.This is the initialisation step of pointer - iptr.
cout<<*iptr;
Here,* is being used with a pointer that has already been decalared and initialised. iptr hold 10500 which is the address of variable i. i holds value 25. Hence, this statements outputs 25.
Important-
The operand of '&' operator is an ordinary variable.
The operand of ' * ' will be a pointer variable always.
The operator
* is used for dereferencing the pointer, that is, accessing the original value.
The operator
& is used for referencing the address of a variable.
Pointer Arithmetic
For normal varibales like int/float, any type of mathematical operation can be applied on them. For pointers, only addition and subtarction can be used.
Rule of pointer arithmetic:
In pointer arithmetic, all pointers increase/decrease by the length (size) of the data type they point to.
This means that if we write:
int* iptr;
iptr += 2;
Here, we want to add two to iptr. However, we will not literally add 2. Writing the above will make iptr point to the second element of iptr's type.
That is, literally, we add the size of int twice to the address stored in iptr.
Eg: if iptr had address 1050, then iptr + 2 becomes:
iptr + (size of two integers) or iptr + 2(size of int) which is equal to 1050 + 2(4) = 1058. //size of int is generally 4 bytes.
1058 is the new address we get. By writing
*(iptr + 2), we can access the value at 1058.
A more clear understanding can be made with the following picture-
Notice, how the address increments by 4 as we keep on adding 1 to ptr because ptr is an integer pointer.
Similarly, by decrementing the pointer value, each time, the same operation depicted above will be applied. Only this time, we will subtract the size of data type.
eg:
iptr -= 2;
= 1050 - 2(4) = 1042.
1042 is the new memory address.
Dynamic Allocation and Pointers:
As already stated, pointers are used for dynamic allocation. The operators that facilitate this process are -
new and
delete.
new - The operator new is used for creating objcts/variables of all types that are to be allocated at run time.
The general syntax:
pointer_variableName = new int; //or any other data type.
The data type of pointer name and data type on RHS must be the same.
eg:
int*iptr; iptr = new int;
or
int*iptr = new int;
Both the above statements behave in exactly the same way. Second form is just shorter to write.
delete - This operator is used to delete or deallocate dynamically allocated memory at the end of the program.
Word of Caution:
It is very important to deallocate all dynamically allocated memory before the program ends. Failing to do so caused memory leaks. This means that each time the program will run, it will keep on allocating memory until we run out of all storage space. Hence, deallocating is important.
To deallocate, write:
delete pointer_variableName;
eg:
delete iptr;
Pointers and Arrays:
Pointers are quite closely connected to arrays. C++ treats the name of the array as a pointer. That is, if we write:
int arr[10];
arr is basically treated as a pointer. arr stores the address of the first element of the array, that is:
arr[0]
Code description-
int *a; int age[10]; cout<<"Enter values for age:"; for(int i = 0; i < 10; i++) { cin>>age[i]; } a = age; //check if both *a and *age have same values or not- cout<<"a points to:"<<*a<<endl; cout<<"age points to:"<<*age;
Input:
3 7 4 9 7 10 6 7 2 1
Output:
3 3
Both a and age point to:
age[0]
Thus, age which is the array name is essentially a pointer pointing to
age[0].
Thus, because age is a pointer, hence writing
cout<<age[3];
and writing
cout<<*(age+3);
mean the same. Both produce output as 9. Thus, essentially, all pointer rules apply to the array name.
Applications of Pointers
- Pointers are used for passing function arguments by reference. Passing by reference means that no copy of the arguments is created within the function and the actual values are operated upon.
For eg:
#include <iostream> using namespace std; void swap(int* x, int* y) { int temp = *x; *x = *y; *y = temp; cout<<x<<" "<<y<<; } int main() { int x = 10, y = 20; swap(&x, &y); cout << x << " " << y << endl; return 0; }

Here, values of x and y are swapped totally and not just within the function.
Implementing data structures: Data structures such as linked lists, trees etc are implemented using pointers in C and C++.
System Level access and programming: Various internal routines are implemented using pointers for speedy access. For eg: the system essentially accesses array elements using pointers.
With this, you will have a complete basic idea of using pointers in C and C++. | https://iq.opengenus.org/pointers-in-cpp/ | CC-MAIN-2020-24 | refinedweb | 1,491 | 63.09 |
I tried to make 11..10..0 (which is binary number with consecutive 32-n zeros in small digits).
// Can assume that 0 <= n <= 31 int masking(int n) { return (~0)<<(~n+33); }
However, when I put
0 in input n, I expected
0, but I got
-1(0xffffffff).
Without using input,
(~0)<<(~0+33) gives
0.
(-1)<<32 also gives
0.
I don't know why I got different results.
You might want to consider forcing 64 bit math. According to "C" standard, result of shifting of a variable with N bits is only defined when the number of shifts is less than the size of the variable (0..N-1)
Performing the shift on (~0) (integer, usually 32 bit), will result in undefined behavior for ~n+33 (n=0) since ~n+33 = 32, above the limit of 31.
Changing the code to use (~0L) produce the requested result masking(0) = 0
Assuming that you run on generic Linux - gcc will default to 32 bit integer, 64 bit long and 64 bit pointer.
include <stdio.h> int masking(int n) { return (~0UL)<<(~n+33); } void main(void) { for (int i=0 ; i<4 ; i++) { printf("M(%d)=%x\n", i, masking(i)) ; } }
Output:
M(0)=0 M(1)=80000000 M(2)=c0000000 M(3)=e0000000

Design patterns have been one of the main topics in software engineering since the book "Design Patterns: Elements of Reusable Object-Oriented Software" (1995). After that there have been also other books of these "GOF-Patterns", like the top rated "Head First Design Patterns". Most of the patterns are still valid, but some of them have become a bit useless in practical Microsoft .NET � environment. One example is the Iterator-pattern (for handling managed collections) because of .NET 2.0 Generics.
The book Head First Design Patterns describes the Template Method Design Pattern as follows:
"Template Method - Define template function and give it functions as parameters? Well, in Microsoft .NET 3.5 we can, so there is alternative way to make the same thing as the Template Method Design Pattern.
Ok, as if we would like to have a software for� let's say� a recipe-making �software for hot drinks. There are some generic methods like: 1. Boil water, 2. Brew, 3. Pour in cup, 4. Add condiments. So let that be the generic template algorithm.
First, what we need is a unit test. VS2008 unit test Template Method Design Pattern will look like this:
Where custom hot drinks (like Coffee, Tea, etc.) override the needed special functionality from the template algorithm class (abstract class called HotDrink).
The source code will look like this: current class diagram:
So, what's wrong with Template Method? Well, one of generally accepted fundamental principle of Object- Oriented design is "Favor Composition Over Inheritance". If the HotDrink �class changes there will be troubles as this was not the most dynamical way. Better design would be looking something like this:
But this will add more complexity. Could we keep the number of our classes and lines of code low? Let's try another solution, with Microsoft .NET 3.5 Framework new functional programming�
We already have the unit test, and it can be exactly same as in the Template Method Design Pattern unit test! Let's see the template algorithm, the class HotDrink: It will also look much like� And now explanation what is "List<Func<string>>":
It's just a list of functions... :-) That Func<string> means a code that we can execute at runtime and the return type for the function is string.
If it would have also input parameters, they would come before the result, so the syntax would be Func<T, T2> where T would be some input type and T2 some return type.
Then those special drinks:
//Making tea recipe public class Tea { public List<string> MakeRecipe() { List<Func<string>> CustomMethods = new List<Func<string>>(){ (() => "Steeping the tea"), // same as delegate(){ return <...>{ �, �, �} is also a new Microsoft .NET 3.5 enhancement called Collection Initializer, just an easier way to fill the list. The syntax (() => "") is lambda expression and means the same than anonymous function delegate(){return "...";} which is like normal function, just typed inline. If method would have much more functionality than just return, then it would be clearer to use (named) delegate. Anonymous delegates won't be visible in the class diagram:
One more thing, I draw:
Let's see if Functional Programming is the way of the future. The real best practices always come after some time has passed.

How to Create an App in Django ?
Prerequisite – How to Create a Basic Project using MVT in Django?
Django is famous for its unique and fully managed app structure. For every functionality, an app can be created like a completely independent module. This article will take you through how to create a basic app and add functionalities using that app.
For example, if you are creating a Blog, Separate modules should be created for Comments, Posts, Login/Logout, etc. In Django, these modules are known as apps. There is a different app for each task.
Benefits of using Django apps –
- Django apps are reusable i.e. a Django app can be used with multiple projects.
- We have loosely coupled i.e. almost independent components
- Multiple developers can work on different components
- Debugging and code organization is easy. Django has an excellent debugger tool.
- It has in-built features like admin pages etc, which reduces the effort of building the same from stratch
Pre-installed apps –
Django provides some pre-installed apps for users. To see pre-installed apps, navigate to projectName –> projectName –> settings.py
In your settings.py file, you will find INSTALLED_APPS. Apps listed in INSTALLED_APPS are provided by Django for the developer’s comfort. :
python manage.py startapp projectApp
Method-2
- To create a basic app in your Django project you need to go to the directory containing manage.py and from there enter the command :
django-admin startapp projectApp
Now you can see your directory structure as under :
- To consider the app in your project you need to specify your project name in INSTALLED_APPS list as follows in settings.py:
Python3
- So, we have finally created an app but to render the app using URLs we need to include the app in our main project so that URLs redirected to that app can be rendered. Let us explore it.
Move to projectName-> projectName -> urls.py and add below code in the header
from django.urls import include
- Now in the list of URL patterns, you need to specify the app name for including your app URLs. Here is the code for it –
Python3
- Now You can use the default MVT model to create URLs, models, views, etc. in your app and they will be automatically included in your main project.
The main feature of Django Apps is independence, every app functions as an independent unit in supporting the main project.
Now the urls.py in the project file will not access the app’s url.
To run your Django Web application properly the following actions must be taken:-
1. Create a file in the apps directory called urls.py
2. Include the following code:
Python3
The above code will call or invoke the function which is defined in the views.py file so that it can be seen properly in the Web browser. Here it is assumed that views.py contains the following code :-
Python3
After adding the above code, go to the settings.py file which is in the project directory, and change the value of ROOT_URLCONF from ‘project.urls’ to ‘app.urls’
From this:-
To this:
3. And then you can run the server(127.0.0.1:8000) and you will get the desired output | https://www.geeksforgeeks.org/how-to-create-an-app-in-django/ | CC-MAIN-2022-33 | refinedweb | 541 | 67.25 |
Common Type Library (CTL)
- CT definitions and FQNs
- CT schema versioning and dependencies
- CT scopes and visibility
- CT management
- Further reading
The Common type library (CTL) is a repository of data type schemas used for all Kaa modules. As more schema types and versions are created, they are recorded in the CTL for future use.
Common type (CT) is a CTL unit representing a set of data type schema versions. Using CTL allows for consistent schema management within a Kaa instance.
CT definitions and FQNs
Schemas used in Kaa are based on the Apache Avro format. Every CT is identified by Fully qualified name (FQN). FQN is a combination of namespace and name attributes defined in the root Avro record of a CT schema. Each CT contains a set of CT schemas with the same FQN and different versions. A CT schema ID is the combination of the schema FQN and version. Any CT schema ID is unique across the CT. After a CT schema is created, it becomes unmodifiable and can only be deleted.
CT schema versioning and dependencies
A CT schema version must be explicitly defined in the CT schema as shown below.
{ "type":"record", "name":"SampleCT", "namespace":"org.kaaproject.sample", "version":1, "dependencies":[ { "fqn":"org.kaaproject.sample.ReferencedCT", "version":2 } ], "fields":[ ... ] }
Attempting to load a CT schema with no version or with a used version will result in an error. A CT schema can have dependencies on other CT schemas. CT schema dependencies are defined as an array of the CT schema IDs (for example, see org.kaaproject.sample.ReferencedCT schema in the code snippet above). Deleting a CT schema is only permitted if its ID is not referenced in any other CT schema. Cyclic dependencies are not permitted. Thus, CT schemas are nodes in a directed acyclic graph of dependencies.
CT scopes and visibility
CTs can be defined within these scopes: system, tenant, and application. Scopes impact the visibility of CTs. For example, a CT defined for application A is not visible for application B. Any FQN is unique within its CT scope. Attempting to create a CT with an FQN that already exists in the same scope will result in an error.
IMPORTANT: You can create a CT with an FQN that already exists in other scope, but this is not recommended. Attempting to do so will result in a warning message.
The expected outcomes of an attempt to create a CT with a non-unique FQN are summarized in the following table.
CT management
You can manage CTs using the Server REST API or the Administration UI.
Get the list of CTs
As Kaa administrator, you can get the list of available system CTs using the REST API call or by clicking System CTL on the Administration UI page.
As Tenant administrator, you can get the list of available Tenant CTs and System CTs using the REST API call or by clicking Tenant CTL on the Administration UI page. Use the Display higher scopes checkbox to toggle visibility of the System CTs.
As Tenant developer, you can get the list of available Tenant CTs and System CTs in the same way as Tenant administrator. In addition, Tenant developer can get the list of available application CTs using the REST API call or by clicking Application CTL on the Administration UI page. Use the Display higher scopes checkbox to toggle visibility of the system and tenant CTs.
View CT details
To view the CT details:
OR
- Open the Administration UI page, select the corresponding CTL and click on the CT in the list. The Common type details page will open.
To view another version of the CT, select it form the Version drop-down list. To create a new version of the CT, click Create new version.
Create a new CT
To create a new CT:
OR
- Open the Administration UI page, select the corresponding CTL and click the Add new type button.
If you want to import a schema file, click Browse, select a
.json file containing your schema, click Upload, then click Add.
NOTE: Kaa administrator creates new system CTs. Tenant administrator creates new tenant CTs. Tenant developer creates new application CTs.
In the Add new type window, fill in all the required fields and click Add.
Delete CT schemas
To delete a schema:
OR
- Open the Common type details page and click Delete.
NOTE: Kaa administrator can delete system CT schemas. Tenant administrator can delete tenant CT schemas. Tenant developer can delete application CT schemas.
Promote CTs
If you want some of your Application scope CTs to be available in the Tenant scope, you neeed to promote them. To do this, you can use the REST API call or use the Promotion feature:
Open the Administration UI page, unfold the Applications list.
In the sub-list of a chosen application, click Application CTL.
Click the CT to open the Common type details page and click Promote.
The CT (including all its versions) is now available in the Tenant scope.
NOTE: You cannot promote a CT from the Application scope if there is a CT in the Tenant scope with the same FQN, or if the CT in question has dependencies on other CTs in the Application scope.
CT schema export
To export a CT schema:
OR
- On the Common type details page of the CT, click Export and select the exporting option.
There are four options for CT schema export:
- shallow: exports the CT schema file.
- deep: exports the CT schema file and a file with all referenced CTs recursively.
- flat: exports the CT schema file and a file with all referenced CTs inline.
- library: exports
.jararchive containing the CT schema and all referenced CTs as compiled java classes.
The java library provides all necessary java structures, including the nested types, in compliance with the CT schema. You can use these java classes in external applications. For example, you can serialize binary log records generated by data collection process. | https://kaaproject.github.io/kaa/docs/v0.10.0/Programming-guide/Key-platform-features/Common-Type-Library/ | CC-MAIN-2021-49 | refinedweb | 997 | 64.91 |
This is the first in a series of posts I plan to do as an introduction to the basics of Appium.
In this post I will walk through how to use tools that come with Appium to record the basic steps of a functional test for a sample iOS application and then how to clean that code up and translate it into a JUnit test that can be run as part of an automated test suite. Future posts will demonstrate how to record similar tests with an Android app and then how to leverage Appium in the cloud to run tests across multiple devices and OS versions.
In my mobile application testing training classes we do a demonstration of how to record Selenium tests using Firefox SeleniumIDE. This is a great mechanism for getting a base functional test recorded for a web application or mobile web application. However, it doesn’t do much good for native mobile applications. So I wanted to get a very simple example built for doing exactly that.
First, a few pre-requisites:
- The Apple XCode iOS Simulator is required to create the recording so a Mac running the latest version of XCode will be needed.
- This should go without saying, but you will need to have Appium installed locally. Get it here:
- The app I am using for this example is the UICatalog app used in many other Appium examples on the web. However, feel free to use your own app or any other one you have available. It is available here:.
Configuring and Starting Appium
In order to record a test we need to configure Appium to run the iOS Simulator and launch the UICatalog app. To do this
- Launch Appium
- Click the Apple button to configure the iOS Simulator.
- Edit the properties to use appropriate iOS versions and launch the UICatalog app. Make sure to check “Full Reset”. This is necessary to ensure that the app environment is cleaned up prior to running the Simulator. If unchecked, Appium will do this by starting and killing the Simulator once prior to starting it again and launching the app. This is fine but will cause your tests to take a lot longer to run (since the Simulator is booted twice).
- Launch the Appium server for iOS by selecting the “Apple” and clicking “Launch”. If everything launches properly, the Appium window should look something like this
- Next open the Inspector by clicking the magnifying glass Icon in the Appium server. This will start the iOS Simulator, load the UICatalog app, and launch the inspector.
- The Inspector is the mechanism we will use to determine locators for elements in the UI and to record the test.
The Appium Inspector
Prior to recording a test it is a good idea to get familiar with the Appium Inspector interface. There are three important areas of the Inspector.
On the left side is a series of vertical boxes. These are the navigators that show the path through the current UI to a particular element (very similar in concept to the OS X Finder interface). The right-most vertical box contains the details of the element being selected. This contains the information needed to locate the element. We will use this later when we write our test case code.
On the far right is a window that mirrors the current screen being displayed in the iOS Simulator. Selecting an element here will highlight it and show the navigator path to get to it as well as the details of the element. Two important things to note:
- Clicking on the element does not interact with it (i.e. this does not send a “click” or “tap” to the iOS Simulator), it simply highlights the element and shows its details. How to interact with elements will be explained in more detail below and when we actually record the test.
- In certain cases elements are nested and are not directly selectable. In this case it may be necessary to click on the parent element and use the navigator to get to the desired element
On the bottom left are a set of buttons used to interact with the elements of the elements. There are several tabs that perform different interactions:
- Touch — contains controls that allow physical input via touch interface (tap, swipe, etc),
- Text — contains controls that allow text to be entered into forms
- Locator — allows for searching the UI to find an element by a particular locator
- Misc — allows interactions with alert windows.
This is a good time to take a minute to get familiar with the interface. Note that whenever an element is clicked it will take several seconds for the mirror window to refresh. Be patient and wait for it, and for the navigator windows, to refresh between taps or other interactions. Also note that the window will not automatically refresh if you interact with the iOS Simulator directly. Clicking the “Refresh” button will refresh the inspector with the current screen displayed on the Simulator.
Recording a Test Case
Now that we have Appium up and running and are familiar with the Inspector interface, it is time to do something interesting and actually record a test. The following steps refer to the figure below.
- To get started, make sure the app is on the main start page and click on the “Record” button. It will turn red to indicate recording is on. Also, another window will drop from the bottom of the Inspector. This is where the code generated by the recorder will appear.
- For those familiar with Firefox IDE, this recorder is very similar in concept but has one significant difference. Instead of recording into Selenese and then requiring you to export into anther language, it records directly into the language of choice. In my case, I chose Java.
- Note also the “Add Boilerplate” check box. When checked this includes boilerplate setup code. For Java, this means that appropriate library imports are included as well as a skeleton class definition, and a default DesiredCapabilities object definition based on the settings we configured earlier. I’m going to leave this checked.
- Now simply use the interaction controls to navigate through the application. For example, select elements in the mirror window or use the navigator to find them and then click the “Tap” button. Code will start to appear in the proper place in the window below the Inspector
- When finished, click “Save” to save the code to a file.
The generated code can now be used as the basis for an automated WebDriver test in JUnit. As an example I clicked around through a couple menus and this was the code that was generated. In the next section we will clean this up so it will actually run.
import io.appium.java_client.AppiumDriver; import org.openqa.selenium.remote.DesiredCapabilities; import java.net.URL; public class {scriptName} {"); wd = new AppiumDriver(new URL(""), capabilities); wd.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS); wd.findElement(By.xpath("//UIAApplication[1]/UIAWindow[2]/UIATableView[1]/UIATableCell[1]")).click(); wd.findElement(By.name("Gray")).close(); } }
Cleaning up the Test
Now that the basic test steps have been recorded into a skeleton Java class we want to do three things:
- Clean up the code so that it will actually run
- Translate the code into a JUnit test
- Add in an assertion so that we have a proper test case
In order to get the code to run, we need to do a few things:
- Add a package statement and any appropriate imports (a good IDE like Eclipse can help out alot with this)
- Replace {scriptName} with the name of the class. In Java this should be the same as the filename.
- Add a private static field named wd of type AppiumDriver.
- Change the statement on line 14 to instantiate IOSDriver instead of AppiumDriver. AppiumDriver is actually an abstract class and can’t be instantiated directly. IOSDriver is a concrete subclass of AppiumDriver appropriate for this iOS test case.
- Surround line 14 with a try/catch block to catch the potential MalformedUrlException that could be thrown
- Change wd.close() on line 24 to wd.quit() because wd.close() is not supported by the IOSDriver.
The resulting code should look something like this. To try it out, ensure that the inspector is not running, nor is the iOS Simulator. Also, it is probably a good idea to just stop and restart the iOS Appium server. Then just run this class.
package com.coveros.training.map.appium; import java.net.MalformedURLException; import java.net.URL; import java.util.concurrent.TimeUnit; import org.openqa.selenium.By; import org.openqa.selenium.remote.DesiredCapabilities; import io.appium.java_client.AppiumDriver; import io.appium.java_client.ios.IOSDriver; import io.appium.java_client.ios.IOSElement; public class CodeMakerTest{ private static AppiumDriver<IOSElement> wd;"); try { wd = new IOSDriver<>(new URL(""), capabilities); } catch (MalformedURLException e) { e.printStackTrace(); } wd.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);.quit(); } }
The next step is to make this a true JUnit test. In order to do this we want to make sure and follow a good setup-execute-tear down pattern. This means we need to get rid of the static main method and break the test into three parts
- setup — define desired capabilities, instantiate the driver and connect to the Appium Server
- execute — locate elements, interact with them and assert that the results are what we expect
- teardown — close the app and shut down the iOS Simulator
The biggest thing that is missing here is the assertion. The inspector does not have a mechanism for recording asserts directly so we will have to write this code ourselves. For my simple example I navigated to the “Pickers” menu and assert that the text displayed for the middle picker button on the bottom of the screen is “UIDatePicker”. To find an appropriate identifier, use the inspector and look at the details for the appropriate element. The code to click on the picker menu and assert the button text looks like this:());
The next step is to write the new setup method. This is essentially the same code that we used previously to set up the DesiredCapabilities object and the AppiumDriver with a few changes:
- Refactored into a class method with the @Before JUnit tag
- Added the “app” capability to explicitly declare the app to be loaded. This will allow us to remove the App Path from the iOS Settings in the Appium server and use the server to run tests against more than one app.
The updated code is as follows
private AppiumDriver<IOSElement> wd; @Before public void setup() { File classpathRoot = new File(System.getenv("HOME")); File appDir = new File(classpathRoot, "Development/appium"); File app = new File(appDir, "UICatalog.app"); DesiredCapabilities capabilities = DesiredCapabilities.iphone(); capabilities.setCapability("appium-version", "1.5.2"); capabilities.setCapability("platformName", "iOS"); capabilities.setCapability("platformVersion", "9.2"); capabilities.setCapability("deviceName", "iPhone 6"); capabilities.setCapability("app", app.getAbsolutePath()); // Don't need a browser for a native app test capabilities.setBrowserName(""); try { wd = new IOSDriver<>(new URL(""), capabilities); wd.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS); wd.launchApp(); } catch (MalformedURLException e) { e.printStackTrace(); fail(); } }
The final step is to write the test execution method and the teardown method. The code for these is essentially unchanged. It has just been moved into two properly annotated methods as follows:
@Test public void testSampleIOSApp() {()); } @After public void tearDown() { wd.closeApp(); wd.quit(); }
Hopefully this helped to get a first unit test written using Appium.

Part of having a great developer experience is having great documentation. A lot goes into creating good docs - the ideal documentation is concise, helpful, accurate, complete, and delightful. Recently we've been working hard to make the docs better based on your feedback, and we wanted to share some of the improvements we've made.
Inline Examples
When you learn a new library, a new programming language, or a new framework, there's a beautiful moment when you first write a bit of code, try it out, see if it works... and it does work. You created something real. We wanted to put that visceral experience right into our docs. Like this:
import React, { Component } from 'react';
import { AppRegistry, Text, View } from 'react-native';
class ScratchPad extends Component {
render() {
return (
<View style={{flex: 1}}>
<Text style={{fontSize: 30, flex: 1, textAlign: 'center'}}>
Isn't this cool?
</Text>
<Text style={{fontSize: 100, flex: 1, textAlign: 'center'}}>
👍
</Text>
</View>
);
}
}
AppRegistry.registerComponent('ScratchPad', () => ScratchPad);
We think these inline examples, using the
react-native-web-player module with help from Devin Abbott, are a great way to learn the basics of React Native, and we have updated our tutorial for new React Native developers to use these wherever possible. Check it out - if you have ever been curious to see what would happen if you modified just one little bit of sample code, this is a really nice way to poke around. Also, if you're building developer tools and you want to show a live React Native sample on your own site,
react-native-web-player can make that straightforward.
The core simulation engine is provided by Nicolas Gallagher's
react-native-web project, which provides a way to display React Native components like
Text and
View on the web. Check out
react-native-web if you're interested in building mobile and web experiences that share a large chunk of the codebase.
Better Guides
In some parts of React Native, there are multiple ways to do things, and we've heard feedback that we could provide better guidance.
We have a new guide to Navigation that compares the different approaches and advises on what you should use -
Navigator,
NavigatorIOS,
NavigationExperimental. In the medium term, we're working towards improving and consolidating those interfaces. In the short term, we hope that a better guide will make your life easier.
We also have a new guide to handling touches that explains some of the basics of making button-like interfaces, and a brief summary of the different ways to handle touch events.
Another area we worked on is Flexbox. This includes tutorials on how to handle layout with Flexbox and how to control the size of components. It also includes an unsexy but hopefully-useful list of all the props that control layout in React Native.
Getting Started
When you start getting a React Native development environment set up on your machine, you do have to do a bunch of installing and configuring things. It's hard to make installation a really fun and exciting experience, but we can at least make it as quick and painless as possible.
We built a new Getting Started workflow that lets you select your development operating system and your mobile operating system up front, to provide one concise place with all the setup instructions. We also went through the installation process to make sure everything worked and to make sure that every decision point had a clear recommendation. After testing it out on our innocent coworkers, we're pretty sure this is an improvement.
We also worked on the guide to integrating React Native into an existing app. Many of the largest apps that use React Native, like the Facebook app itself, actually build part of the app in React Native, and part of it using regular development tools. We hope this guide makes it easier for more people to build apps this way.
We Need Your Help
Your feedback lets us know what we should prioritize. I know some people will read this blog post and think "Better docs? Pffft. The documentation for X is still garbage!". That's great - we need that energy. The best way to give us feedback depends on the sort of feedback.
If you find a mistake in the documentation, like inaccurate descriptions or code that doesn't actually work, file an issue. Tag it with "Documentation", so that it's easier to route it to the right people.
If there isn't a specific mistake, but something in the documentation is fundamentally confusing, it's not a great fit for a GitHub issue. Instead, post on Canny about the area of the docs that could use help. This helps us prioritize when we are doing more general work like guide-writing.

im a NEWBIE!!! to C# and following a book... and the code isnt doing as the book says..the book is telling me to use the Unity 3d engine
plz keep it as newbie friendly as possible thank you
he code and the output isnt matching up right...what am i doing wrong...
I recommend posting over in the Unity Forum.
My Code Guru Articles
thx u..but I thought about that...but unity has it own language
and figured if I posted their no one would use c#
Unfortunately, I can't read the text in the picture you've posted so I can't be much help.
well im at work atm when I get home ill put the block of code in the post
here is my code...
using UnityEngine;
using System.Collections;
public class Leaningscript : MonoBehaviour
{
public int myNumber = 10;
// Use this for initialization
void Start ()
{
Debug.Log(2 + 9);//non varible should show 11
Debug.Log(11 + myNumber); //using varibles should show 21
}
// Update is called once per frame
void Update ()
{
}
}
now the line that should appear as 21 out puts as 20...
i found out that if i change the variable in the code itself it doesnt change...
but if i change it in the inspector panel it will change...so i guess i should prolly
take this to the unity forums site....thx for ur help tho

Following my previous post on Optimizing Javascript, I thought I’d write a similar post regarding Python optimization.
Before going on to the more interesting stuff, there are a few issues that need to be addressed:
0. Basics
Know the basics – especially profiling!
Just by looking at the profiling output, you can tell where does the computing time go. To get that information, I like to sort on cumulative time (i.e, time taken by a given function and all functions called from it, over all of its calls).
0.5. Knowing your goal, and your enemy
The kind of optimizations you do, and how far you’re willing to go is dependent on your code’s users. If you’re writing batch processing software, your required time for running might be a minute, an hour, or a day. So far, I had to optimize various cases of weeks to minutes for batch processing and also seconds to milliseconds for web-application UI.
Your timing should apply to typical input, and probably to your biggest probable input as well.
Create some simple benchmark you can test your code against. It’s important that your benchmark be typical ‘complexity-wise’, but smaller in size, so that running it and getting profiling results takes no more than a few seconds. You may even want multiple benchmarks, each one for a different size. That way, once you are more sure of yourself, you can run your code against the larger benchmark. If your benchmarks are real inputs – all the better.
1. Python vs. C and similar considerations
In my line of work, I usually do research oriented development. That means that it’s harder to know upfront where the bottlenecks will be. As a result, the prevailing attitude is usually “let’s write it in Python, and later, when the need arises, convert the critical code to C”.
So far, I haven’t had the chance to do that. Usually what happens is we write the code, it works well enough, and we figure that the flexibility of writing it in Python is more important than the Python to C conversion gains. Also, Python is not always the bottleneck – sometimes it’s a database, or some 3rd party API.
Usually “import pysco”, and changing the code to allow parallel processing is cheaper and simpler than the conversion to C.
2. The small time-eater
A common problem is when a relatively trivial function is taking a lot of cumulative time. That’s usually a sign you’re doing something wrong. I had this issue when I used my symbolic constants for a new project. Consider the following:
def SymbolInt(value, name): class _SymbolInt(int): def __str__(self): return name def __repr__(self): return 'SymbolInt(%d, "%s")' % (value, name) def __eq__(self, other): if isinstance(other, str): other = other.lower() return int(self)==other or name.lower() == other def __ne__(self, other): return not self == other return _SymbolInt(value)
This one is very nice for interactive interfaces. However, in the new project, I found out that __eq__ was taking *a lot* of time. Way more than it should, even when I wasn’t comparing SymbolInt-s to strings!
It turned out that ‘or name.lower() == other’ was very bad speed wise. So for that project, I removed this subcondition, and voila! My code was fast!
3. The algorithm is critical
In many cases I’ve worked on, the greatest reductions in running time were due to algorithm changes. That means that playing with issues such as variable lookups and so on should come after you’re mostly settled on your algorithm. The latest example that I can think of is the set counting problem, where using my solution got me down from two weeks to 20 something minutes on my real input.
Later I did some simpler optimizations that chopped off a few more minutes.
4. Avoiding loops
That one is easy. Everyone knows you should avoid loops, especially nested ones. Still, there are some cases where your code just has to have these loops – because that’s the essence of what your code is doing.
To make loop avoidance possible, and specifically cartesian product kind of loops, consider refactoring your code to use set intersections and unions. As simple illustration, consider:
Instead of this,
for x in a: for y in b: if x == y: yield (x,y)
do this:
return set(a) & set(b)
Sometimes, applying this change doesn’t quite fit your algorithm. In that cases, try to change your algorithm to accommodate. For example, it might yield less accurate results. In that case, aim for returning more than you need, and then do a second pass to filter the bad ones. The time gains from avoiding the extra loops should still be worth it.
(Note: this is similar to doing your computations in your database queries instead of in your code. Similar ideas apply.)
5. Lookups
If you spend time looking for something, use a dict. If that is not feasable, use any other data-structure that fits your problem. For example, let’s say you’re looking for given strings in a lot of files. You can build a small index beforehand, and instead of looking at the files each time, just look at this index.
(Note: this is similar to creating an index on the database column you are searching on.)
6. Memory
When dealing with large inputs, you’ll usually want to reduce your memory requirements. Consider an algorithm that requires O(n) memory, for n-sized inputs. All you need is a factor of 4, and 500 megs of input, and your code will choke on many current machines.
Also, I’ve found out that writing your code in such a way as to use drastically less memory, will sometimes force me to write it more time-efficiently as well.
There are a few techniques to dealing with the memory issue. The central idea is to have as little of your data as you need available at any time.
7. Generators
Generator expressions are usually preferable to list comprehensions. Similarly, consider replacing this kind of functions:
def myfunc(some_input): ... result = [] for bla in foo: ... result.append(bar) return result
with the following idiom:
def myfunc(some_input): ... for bla in foo: ... yield bar
This has the added advantage of simplifying myfunc, as its state is kept for you. On really big inputs and outputs, this one could save you from keeping all of your output in memory.
If you are not familiar with generators, I suggest reading David Beazley’s presentation on the subject, it’s an excellent read, regardless of optimizations.
8. Outputs
If your goal is to generate output, dump it to a file as soon as possible. This is made simple by the previous idiom:
for bar in myfunc(): #process bar ... dump(foobar)
Just make sure that dump doesn’t keep your data around for too long.
For example, I once had to insert a lot of data into a database. After I finished processing each record, I would insert it. The bottleneck was the database. I tried flushing only after several inserts (which meant inserts in chunks of N for various N), until I was introduced to the solution: bulk inserts.
The, my extraction script just dumped to a text file, which was lightning fast, and later I did the bulk insert.
9. Summing up
Do
sum(x for x in some_generator)
Instead of
for x in some_list: my_sum += x
Kidding!
Use your profiler, your head, psyco, and more experienced advice in the best order that suits you. As I’ve come to learn, getting advice from friends is an excellent way to avoid bashing your head against some mad bugger’s O(n2) wall.
Really nice info, I agree with everything. I’ve met lazy people (as programmers should be) that skip the profiling step and just guess where they need to optimize so I’d like to +1 how important it is. Not to mention it’s easy:
import profile
profile.run(“any_python_expression”)
where usually you’d replace any_python_expression with a call to your main function…
One more…
Understand where your program fits. It may be easier to optimise a cooperating program rather than the current one, to gain the performance gain needed for the whole system.
- Paddy.
Thanks for posting this. I found it to be very practical and helpful.
One cheap trick you can also use is to cache a method call in a tight loop. Method lookups can be expensive, so for example in:
> for i in xrange(1000):
> myobj.compute(i)
you can eliminate the lookup:
> compute = myobj.compute
> for i in xrange(1000):
> compute(i)
Great post, thanks.
I guess the bottom line is that an algorithm should be designed for performance and later use profiling to improve implementation speed.
Benny,
It might be best to design first for correctness and then address any performance issues.

# Enumerable: How to yield a business value
This article is a brief explanation about how using a common language keywords might have an influence on the budget of IT-infrastructure of a project or help to achieve some limitations/restrictions of hosting infrastructure and, moreover, will be a good sing of the quality and maturity of the source code.
For the demonstration of ideas, in the article will be using C# language, but most of the ideas may be translated into other languages.
From the set of language's features, from my point of view, 'yield' is the most undervalued keyword. You can read the documentation and find a huge bunch of examples on the Internet. To be short, let's say that 'yield' allow creating 'iterators' implicitly. By design, an iterator should expose an IEnumerable source for 'public' usage. And here the tricky starts. Because we have a lot of implementations of IEnumerable in the language: list, dictionary, hashset, queue and etc. And from my experience, the choice of one of them for satisfaction requirements of some business task is wrong. Moreover, all of this is aggravated by whatever implementation is chosen, the program 'just works' — this is what really needs for business, isn't it? Commonly, it works, but only until the service is deployed into a production environment.
For a demonstration of the problem, I suggest choosing very common business case/flow for most enterprise project which we can extend during the article and substitute some part of this flow for understanding a scale of influence this approach on enterprise projects. And it should help you to find your own case in this set to fix it.
Example of the task:
1. Load byline a set of records from a file or DB into memory.
2. For each column of the record change the value to someone other value.
3. Save the results of transformation into a file or DB.
Let's assume several cases where this logic may be applicable. At this moment, I see two cases:
1. It is maybe a part of flow for some console ETL application.
2. It is maybe a logic inside of action in Controller of MVC application .
If we paraphrase the task into a more technical manner, so it may be sound like this: "(1)Allocate an amount of memory, (2) load information into memory from persistence storage, (3)modify and (4)flush records changes in memory to the persistence storage." Here the first phrase in the description "(1)Allocate an amount of memory" may have a real correlation to your non-functional requirements. Because your job/service should 'live' in some hosting environment which may have some limitations/restrictions(for instance, 150Mb per micro-service) and to predict spendings on your service in budget, we should predict, in our case amount of memory which service will use (commonly we say about maximum amounts of memory). In other words, we should determine a memory 'footprint' for your service.
Let's consider a memory footprint for really common implementation which I observe from time to time in different codebases of enterprise projects. Also, you can try to find it in your projects too, for example, 'under the hood' of 'repository' pattern implementation, just try to find such words: 'ToList', 'ToArray', 'ToReadonlyCollection' and etc. All of such implementation means that:
1. For each line/record into file/db, allocates memory to hold properties of record from file/db (i.e. var user = new User() { FirstName = 'Test', LastName = 'Test2' })
2. Next, with help of, for example, 'ToArray' or manually, object's references are held into some collection (i.e. var users = new List(); users.Add(user)). So, it is allocated some amount of memory for each record from a file and not to forget about it, the reference is stored into some collection.
Here is an example:
```
private static IEnumerable LoadUsers2()
{
var list = new List();
foreach(var line in File.ReadLines("text.txt"))
{
var splittedLine = line.Split(';');
list.Add(new User()
{
FirstName = splittedLine[0],
LastName = splittedLine[1]
});
}
return list;
// or
return File.ReadLines("text.txt")
.Select(line => line.Split(';'))
.Select(splittedLine => new User()
{
FirstName = splittedLine[0],
LastName = splittedLine[1]
}).ToArray();
}
```
Memory profiler results:
Exactly such picture I saw every time in prodaction environment before container stops/reloads due to hosting's resource limitation per container.
So, a footprint for this case, roughly, depends on the number of records into a file. Because memory allocates per record in the file. And, the sum of this small peases of memory give us a maximum amount of memory which may be consumed by our service — it is the footprint of the service. But is this footprint predictable? Apparently, no. Because we can not predict a number of records in the file. And, in most case, the file size exceeds the amount of allowed memory in hosting in several times. It means that it is hard to use such implementation in the production environment.
Looks like it is the moment to re-thinks such implementation. Next assumption may give us more opportunities to calculate a footprint for the service: «a footprint should depend on the size only ONE record in the file». Roughly, in this case, we can calculate the maximum size of each column of only one record and sum them. It is quite easy to predict the size of a record instead of prediction of the number of records in the file.
**And it is really wondered that we can implement a service which may handle an unpredictable amount of records and constantly consumes only a couple of megabytes with help only one keyword — 'yield'\*.**
The time for an example:
```
class Program
{
static void Main(string[] args)
{
// 1. Load byline a set of records from a file or DB into memory.
var users = LoadUsers();
// 2. For each column of the record change the value to someone other value.
users = ModifyFirstName(users);
// 3. Save the results of transformation into a file or DB.
SaveUsers(users);
}
private static IEnumerable LoadUsers()
{
foreach(var line in File.ReadLines("text.txt"))
{
var splitedLine = line.Split(';');
yield return new User()
{
FirstName = splitedLine[0],
LastName = splitedLine[1]
};
}
}
private static IEnumerable ModifyFirstName(IEnumerable users)
{
foreach (var user in users)
{
user.FirstName += "\_1";
yield return user;
}
}
private static void SaveUsers(IEnumerable users)
{
foreach(var user in users)
{
File.AppendAllLines("results.txt", new string []{ user.FirstName + ';' + user.LastName });
}
}
private class User
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
}
```
As you can see in the example above, there is allocates memory only for one object at a time: 'yield return new User()' instead of creating a collection and fills it with objects. It is the main point of optimization which allows us to calculate more predictable memory footprint for the service. Because we only need to know the size of two fields, in our case FirstName and LastName. When a modified user is saved into file (see File.AppendAllLines), the instance of the user object is available for garbage collection. And memory which is occupied by the object is deallocated (i.e. the next iteration of 'foreach' statement in LoadUsers), so the next instance of user object may be created. In other words, roughly, the same amount of memory replaces by the same amount of memory on each iteration. That is why we no need more memory than the size of a single record in the file.
Memory profiler results after optimization:
From another perspective, if we slightly rename a couple of methods in the implementation above, so that use can notice some meaningful logic for Controllers in MVC application:
```
private static void GetUsersAction()
{
// 1. Load byline a set of records from a file or DB into memory.
var users = LoadUsers();
// 2. For each column of the record change the value to someone other value.
var usersDTOs = MapToDTO(users);
// 3. Save the results of transformation into a file or DB.
OkResult(usersDTOs);
}
```
One important note before code listing: most of the important libraries like EntityFramework, ASP.net MVC, AutoMapper, Dapper, NHibernate, ADO.net and etc expose/consume IEnumerables sources. So, it means in the example above that LoadUsers may be replaced by an implementation which uses EntityFramework, for example. Which loads data row by row from the DB table, instead of a file. MapToDTO may be replaced by Automapper and OkResult may be replaced by a 'real' implementation of IActionResult in some MVC framework or our own implementation base on network stream, for example:
```
private static void OkResult(IEnumerable users)
{
// you can use a networksteam implementation
using(StreamWriter sw = new StreamWriter("result.txt"))
{
foreach(var user in users)
{
sw.WriteLine(user.FirstName + ';' + user.LastName);
}
}
}
```
This 'mvc-like' example shows us that we still able to predict and calculate a memory footprint also for Web-application. But in this case, it will be depends on requests count also. For example, the non-functional requirements may sound in this way: «Maximum memory amount for 1000 request not more then: 200KB per user object x 1000 requests ~ 200MB».
Such calculations are very useful for performance optimization in case of scaling the web application. For instance, you need to scale your web application on 100 containers/VMs. So, in this case, to make a decision about how much resources you should allocate from hosting provider, so you can adjust the formula like this: 200KB per user object x 1000 requests x 100VMs ~ 20GB. Moreover, this is the maximum amount of memory and this is amount is under the control of your project's budget.

The docker environment accompanying this guide provides mitmweb to inspect requests sent to the NIS instance running in the container. This section will show how to use it.
We will send requests to out NIS in the ruby language, using the rest-client gem.
We will try to get the block at the current height, which, as we have already seen, is obtained by sending a POST request to
/block/public/at with
a JSON payload telling the height of the block we want to retrieve.
According to the documentation of rest-client this is done easily. We will do it in the interactive ruby interpreter that can be
started with the command
irb in the tools container. Once in the interpreter, we type
require 'rest-client' RestClient.post '', {'height': '243'}
This however returns an error message:):2 from /usr/bin/irb:11:in `<main>'
This error message is not very helpful, so we might want to take a look at the mitmweb page available at
after you start containers with the script
ndev as explained ealier.
Opening Mitmweb in your browser (use Firefox if you get a blank page in Google Chrome), and selecting the last request in the list,
you should see a page similar to this:
The left pane lists the requests it has been intercepted (2 in this case), and
the right pane gives you a detailed view of the request and response headers.
The User-Agent header shows this request has been sent by rest-client to the
host nemdevnis (the container running our NIS instance) with a content type
header
application/x-www-form-urlencoded.
Clicking on the Response link of the right tab shows this:
This is already much more informative. It means our request sent its data in an encoding not supported
by the server.
We can fix this by setting the content type header to json and ensure we send a json payload:
require 'rest-client' require 'json' RestClient.post '', {'height': '243'}.to_json, {content_type: :json, accept: :json}
This still yields an error in ruby, which is not much clearer:):10 from /usr/bin/irb:11:in `<main>'
It reports a incompatible value for the property height. Looking at the request details, we have:
We see at the bottom that the text passed as value is valid JSON. If we don't see what's wrong here,
we can send the same request with a tool that gave a succesful response. In our case, this is a request
we already sent with httpie.
We know that issuing the command
http :7890/block/at/public height:=243 yields a successful result.
Let's just issue that command and look at the request headers. Here are the details of the request sent by
httpie:
Did you spot the difference? Httpie sent
{ "height": 243 }
while with rest-client we sent:
{ "height": "243" }
We send the value of the
height property as a string, whereas it should be an integer.
Let's see if this fixes our problem:
require 'rest-client' require 'json' resp=RestClient.post '', {'height': 243}.to_json, {content_type: :json, accept: :json} => <RestClient::Response 200 "{\"timeStamp...">
Sure enough! We now successfully debugged and sent a request from Ruby.
Debugging websockets is not as accessible as debugging your HTTP requests. There's no perfect solution, and we will debug websocket connections with the Google Chrome console, as well as with Wireshark. None of these is great to debug websockets, but combining both tools might help you get forward.
In this section, we will not open websocket connections ourselves, but we will see how to observe the traffic on the websocket connections opened by the NanoWallet.
You can open the Google Chrome inspctor by pressing CTRL-SHIFT-I. In the Inspector, select the
Network tab (surrounded in screenshot), and select to only
display websockets by clicking on
WS (indicated by the red arrow in the screenshot).
If you open the inpector on a page that is loaded, you will have to reload the page as indicated:
When you login to the NanoWallet with the Inspector open and with the filter displaying only websocket connections, you will see a websocket connection established:
By selecting the connection in the list, you can take a closer look to the connection. By default, the detailed view of the connection open on the headers tab showing all headers of the connection, both for request and response:
The websocket connection is a persistent connection over which multiple data frames are exchanged. Luckily, the inspector lets us take a close look at the frames exchanged. Selecting the Frames tab gives you a list of frames exchanged over the connection. This list is updated automatically as new frames are exchanged:
Let's focus a bit on the frames list after opening a wallet in the NanoWallet client:
Outgoing messages have a light-green background, incoming messages have a white background. WebSocket opcodes are light-yellow and errors are light-red (from the Google Chrome documentation).
We see that we send a frame to connected, and we get confirmation that we have successfully connected.
After that, the NanoWallet client subscribes to multiple notifications. We see a total of 9 subscriptions
(sub-0 to sub-9) for information regarding the account
TA6XFSJYZYAIYP7FL7X2RL63647FRMB65YC6CO3G like
transactions, mosaics, namespaces. There are also global subscriptions for errors and new blocks. Subscription
related information have been highlighted in red in the screenshot.
In addition to subscriptions, some other frames are sent to request information about the account. Subscriptions will only get messages sent when an update is available, but the NanoWallet client needs to retrieve that information to display the current status of the account. This is done by sending SEND command messages. The information regarding these requests are highlighted in blue in the screenshot. We see that the information requested covers the account details, the transactions of that account, as well as the mosaics and namespaces.
Following that are some frames received in relation with the 9 subscriptions just created. The first MESSAGE
received is part of
sub-0
Selecting a frame in that list will display its content:
But here is the result is far from great. The frame's content is just displayed on one line, which does not ease reading and analysing the frame....
Advanced socket information can be gathered from the Google Chrome internal socket details available at chrome://net-internals/#sockets, but this is out of scope for this guide.
The container nis container provided with this guide automatically collects traces of the network traffic to and from
the NIS instance it runs. The traces are stored in the
traces subdirectory of the directory you configured as the location
for the persistent data. See the variable
persistent_location in the file
settings.sh in the same location as the
ndev
executable used to control the containers.
Two traces are captured:
nis.pcap for traffic on port 7890 (http requests) and
ws.pcap for traffic on port 7778 (websockets).
We will use the ws.pcap file to observe websocket traffic.
A great tool to analyse the traces captured is Wireshark, and this is what we will use. It is free software, available for Linux, Mac and Windows.
When you start Wireshark, you will not start a live capture but open the existing capture file available in the persistent
location you configured. But as that file is continuously updated, you will git this error:
This is not a problem for our analysis, it just means that we have openen a file in which the last packet was not completely written to disk. All packets in the trace are usable though, and will give us a detailed view on the websocket traffic.
When you open the traces file, you get something like this:
Each line is a TCP packet, and aggregated views for supported protocols (like HTTP, websocket, etc) also have a line displayed.
We are only interested in websocket traffic, so we can filter to only display the lines of interest. Enter

This result in the list only displaying websocket protocol information, offering a higher level view than the TCP packets,
in which we are not interested for our analysis.
As in our analysis with Google Chrome, we see the CONNECT packet sent by our browser:
We know that this frame is sent by our client, so we deduce that the server address is 172.18.0.3, and the client address
is 172.18.0.2.
Following by the CONNECT request, we receive a CONNECTED message confirming our websocket connection is successfully established:
We also see the subscription request being sent:
The first request is displayed individually, but the other subscription requests are grouped in one entry:
After that are the SEND command sent by the client:
and the MESSAGEs received from the server:
But here again, the display is not perfect, but this description should help you get up to speed regarding the debugging of your websocket requests. | http://docs.nem.io/en/nem-dev-basics-docker/debug-nis-websockets | CC-MAIN-2018-47 | refinedweb | 1,505 | 59.64 |
Line Detection. [closed]
After increasing the minLineLength and decreasing maxLineGap program is still showing number of lines and also the gap is also visible.
Can someone tell me the problem in the program? Image is:-
Code is-:
include "stdafx.h" include <cv.h> include <highgui.h> include <math.h> using namespace cv; int main(int argc, char** argv) { Mat src, dst, color_dst; src = imread("line2.jpg", 0); Canny(src, dst, 50, 200, 3); cvtColor(dst, color_dst, CV_GRAY2BGR); vector<Vec4i> lines; HoughLinesP(dst,lines,1,CV_PI/180,80,600,300); for (size_t i = 0; i < lines.size(); i++) { line(color_dst, Point(lines[i][0], lines[i][1]), Point(lines[i][2], lines[i][3]), Scalar(0, 0, 255), 3, 8); } namedWindow("Source", 1); imshow("Source", src); namedWindow("Detected Lines", 1); imshow("Detected Lines", color_dst); waitKey(0); return(0); }
IT is due to the fact you are using a canny filter. Offcourse this will generate double edges if you increase the line thickness. Why not apply dilate and erode operations. First dilate enough to merge them, then erode the same amount and only a single line will remain.
ya it's good to use morphological operations but HoughP transform already have parameters to do this. Can you tell me the working and use of last 2 parameters in which i have given 600 and 300 value?
Just go for the manual erosion dilation which gives you way more control than the embedded options. That is what I prefer in my software.
Actually if I will use morphological operations, the edges on which I have to work will be lost! Since they are of same thickness.
I think that you are using the opposite operation, try the other way (open <-> close, dilate <-> erode, top hat <-> black hat)
Since all the edges are of same thickness it doesn't matter what I should use first opening or closing. I want to use the parameters in Hough P Transform to eliminate redundant lines.
I do not know more than the docs, but you can test it and verify what is happening when changing the parameters. Do this one by one, so you do not change more than one parameter at once.
@Vivek Goel : that is not correct! If you apply dilate first then reduce, then lines will NOT dissappear! Only the thickest line will be a bit thicker...
Will canny give edges of different thickness? Since if the canny output give edges of different thickness then it will be correct solution but if the detected edges are of same thickness then the morphological operations will be much hard to calibrate and I will to design a much good and sophisticated structuring element.
At first all edges are equal, but at a certain moment the two closest edges merge with dilation into a single element. Applying the same amount of erosion elements then will not remove the others NOR will it return to 2 edges. I do not see the problem. I think you are missing something. | https://answers.opencv.org/question/44760/line-detection/ | CC-MAIN-2021-21 | refinedweb | 501 | 64.81 |
How to use "characteristic.write(value)"
What i want is when the Lopy ble received a string then reply a string.
so i think i need to use "characteristic.read()" and "characteristic.write(value)" in class GATTCCharacteristic.
How to use them?
@jmarcelino
Thank you,it works now. The lightBlue get the reply in reads.
- jmarcelino
@DongYin
There you set reply value using
characteristic.value(b'Your reply')so next time your client (the other device) reads it will get your reply.
@jmarcelino
Thank you for explain .These are my codes.
from network import Bluetooth #from machine import Pin #TestButton = Pin('P23', mode=Pin.IN, pull=Pin.PULL_UP) bluetooth = Bluetooth() bluetooth.set_advertisement(name='LoPy', service_uuid=b'123456789'1234567890123456', isprimary=True) chr1 = srv1.characteristic(uuid=b'2234567890123456', value=6) def char1_cb(chr): print("Write request with value = {}".format(chr.value())) if chr.value() == b'\xdd' : print("reply here") #reply here char1_cb = chr1.callback(trigger=Bluetooth.CHAR_WRITE_EVENT, handler=char1_cb)
so, how to use CHAR_READ_EVENT at
#reply here.
- jmarcelino
That is one way to do it, where the LoPy connects to a service and characteristic on the other device.
In that case you'd usually setup a NOTIFY callback on the LoPy with:
characteristic.callback(trigger=Bluetooth.CHAR_NOTIFY_EVENT, handler=YourFunctionHere)
When the other device writes to the characteristic you'll get a notification that the value has changed and you can then characteristic.read() it.
After that you can characteristic.write(b'Your Reply') if you're reusing the same characteristic.
As I said this is just one of the ways to do it. Another would be to do the opposite, have the other device connect to the LoPy and accept a write from the other device (via a Bluetooth.CHAR_WRITE_EVENT event callback) and then reply to a read from it (a Bluetooth.CHAR_READ_EVENT event). For that you could use something like the GATTSCharacteristic example: | https://forum.pycom.io/topic/859/how-to-use-characteristic-write-value | CC-MAIN-2018-17 | refinedweb | 311 | 53.68 |

Kirkula replied to Kirkula's topic in For Beginnersoh man, what a dope I am! lol, thanks matt!
Experienced programmer, where do I start?
Kirkula replied to fligex's topic in For BeginnersInstead of "playing" the video games, try analyzing them. Look at them like a programmer, like you would any other program. Think about how every frame would be coded, for instance, say you're making asteroids. Think down to just one frame. You have the ship in the middle, the asteroids flying around, the score and lives at the top. There you go, you have a few objects already. Now unpause that, and you have animation. Well, all that is is just a continuous loop that has changes in every iteration, depending on what happens in the game. You also have the controller, so there's input to worry about. And, of course, the screen, so you have to draw to that. When you destroy an asteroid, they would split or be destroyed, and your score would go up. Destroy them all, and you get to the next level, or new frame/scene. When you die, your lives would be reduced by one, and when you run out of lives, the game loop ends. You can either restart it, or close it all together. So basically, you just have to scrutinize every aspect of a game. Think about it like a programmer, not a gamer, and you should be all set. I'm sure there are plenty of books on the subject as well. Have fun!
CryEngine 3 or Unity 3d?

C++, should I switch?
Kirkula replied to superman3275's topic in For BeginnersI don't see why there's a need to "switch" to a language from another one. From my limited knowledge, it's my understanding that once you've mastered a lower level language such as C++, you're able to accomplish MUCH more than you ever can from higher ones, such as C# or Java (which both require virtualization) Instead of "switching" you should be "adding". The good thing about Java is that almost EVERYONE has the JVM, so programming in that will mean almost everyone will be able to run your programming. Also, you don't have to worry about optimization for every machine on the market. The bad thing is, being it's a higher level language, it will run slower, and you have less control over what the program can do. The good thing about C# is that, with XNA, you can make games for the XBox. The bad thing is the craziness you have to deal with when trying to monetize said game. From what I understand, it's friggin nuts trying to deal with them. With java, you can make games and sell them on countless websites, even Steam. Then again, you can do the same with C#, I would imagine. The moral is, don't SWITCH your language...add to your repertoire! Don't stop using C++ while you learn other languages, continue keeping it fresh in your mind and fingers, and when you start to feel like you've brought yourself up to par with your knowledge in another language as compared to your knowledge in C++, either learn more in C++, or add another language! From what I understand, every language can do everything, but some languages do some things better than others. If you know all these languages, you'll know what's good for what, and what you should avoid using for such and such!
Help me figure out what I'm doing wrong, please!
Kirkula posted a topic in For BeginnersSo I've read a good bit of a couple of books on Java. Java: The Complete Reference 8th edition by oracle press, and Java: How to Program 8th edition by Deitel. Mind you, I never finished either book, only halfway through each, so maybe that's why I can't figure this out. Or perhaps I'm just being a complete retard that's been working all day on his first real class and has brain freeze, lol. So anyway, here's the code: [source lang="java"]import java.util.Random; public class Planet { private Random rand; private double mass; private double xPos, yPos; private double xVel, yVel; /** constructors */ Planet(){ setMass(); setPos(); setVelocity(); } Planet(double m){ mass = m; setPos(); setVelocity(); } Planet(double x, double y){ setMass(); xPos = x; yPos = y; setVelocity(); } Planet(double x, double y, double m){ mass = m; xPos = x; yPos = y; setVelocity(); } Planet(double x, double y, double i, double j, double m){ mass = m; xPos = x; yPos = y; xVel = i; yVel = j; } /** returns distance from calling object * * @param x is the xPos of the calling object * @param y is the yPos of the calling object */ double distance(double x, double y){ double distX = Math.abs(xPos - x); double distY = Math.abs(yPos - y); return Math.sqrt(distX * distX + distY * distY); } /** returns unit-length x vector pointing from this to calling object * * @param x is the xPos of calling object * @param dist is the value returned from distance() */ double dirX(double x, double dist){ return (x - xPos) / dist; } /** returns unit-length y vector pointing from this to calling object * * @param y is the yPos of calling object * @param dist is the value returned from distance() */ double dirY(double y, double dist){ return (y - yPos) / dist; } /** calculates acceleration scalar for calling object * * @param m is the mass of the calling object * @param dist is the value returned from distance() */ double accelScalar(double m, double dist){ return (6.674e-11 * m) / (dist * dist); } /** translates this object on XY plane. * should be called before accelerate. */ void translate(){ xPos += xVel; yPos += yVel; } /** determines delta V for calling object. * should be called after translate. * * @param as is the value returned from accelScalar() * @param dX is the value returned from dirX() * @param dY is the value returned from dirY() */ void accelerate(double as, double dX, double dY){ xVel += as * dX; yVel += as * dY; } void setMass(){ double d = rand.nextDouble() * 10.0; int e = (Math.abs(rand.nextInt()) % 6) + 22; setMass(d, e); } void setMass(double d, int e){ mass = Math.pow(d, e); } void setPos(){ int w = 800; int h = 600; double x = rand.nextDouble() * w; double y = rand.nextDouble() * h; setPos(x, y); } void setPos(double x, double y){ xPos = x; yPos = y; } void setVelocity(){ double x = rand.nextDouble() * 50000.0; double y = rand.nextDouble() * 50000.0; setVelocity(x, y); } void setVelocity(double x, double y){ xVel = x; yVel = y; } double[] getPos(){ double[] pos = {xPos, yPos}; return pos; } double[] getVelocity(){ double[] vel = {xVel, yVel}; return vel; } double getXPos(){ return xPos; } double getYpos(){ return yPos; } double getXVelocity(){ return xVel; } double getYVelocity(){ return yVel; } public String toString(){ return "X: " + xPos + "\tY: " + yPos; } } [/source] I'm getting a NullPointerException argument at line 129, the setMass() method. It works perfectly fine when I build the object using the full set of constructor arguments. Can anyone tell me where my problem is?

Need opinion on game directional control keys.
Kirkula replied to wyattbiker's topic in For BeginnersThis type of control is nothing new, really. In many older games like this, most of the time you would control in 1 of 2 ways: 1) the way you were suggesting, with W = Accelerate, A = CounterClockwise, S = Decelerate/Reverse, D = ClockWise. 2) W = Up, A = Left, S = Down, D = Right. Either way is just as good, depends on the end user I suppose (I was always partial to type 1 myself). Type 1 may take a bit longer to get used to, but it will be more impressive with the idea of changing speeds and the ability of reverse, instead of just up, down, left, right. Map rotation would be nice, but I don't think it suites top down views, might get people dizzy :-P hehe.

VC# '05, or VC# '08....which one should I learn on?
Kirkula posted a topic in For BeginnersI have downloaded both some time ago, and now I'm starting to get more serious about learning. I downloaded '05 because XNA was only available for that one, but I downloaded '08 as well, if only because, hey, it's there. Unfortanately though, I don't know which one I should spend more time learning. I'm leaning towards '08, because by the time I'm ready for my first games, the full XNA 3 will be available. I appreciate your thoughts on the matter, and if this was already posted by someone else, or answered in a FAQ, I appologize for the redundancy, but I'm on my way to the shower and off to borders for a book to start learning. I'll be purchasing whichever one you guys recommend, based on '05 or '08, or I'll just think of which version to go through while I'm there :-D. Thanks for your time.

The prime motivation for me to go through Qt licensing documentation and installing Qt Creator IDE was to explore the new UI infrastructure introduced in Qt 5 under the umbrella of “Qt Quick“. As far as I can tell, this is an entirely different system for creating user interface of a Qt application. Built with modern ideas such as OpenGL graphics acceleration for animation effects and UI layout declared with a text-based markup language QML (probably stands for Qt Markup Language.)
Up to this point my experience with building graphics user interface in Qt was with the QWidget-based infrastructure, which has a long lineage in past editions of Qt. Qt Quick is new for Qt5 and seem to share nothing in common with QWidget other than both a part of Qt5. Now that I’ve had a bit of QWidget UI work under my belt I wanted to see what Qt Quick has to offer. And this starts with a smoke test to make sure I could run Qt Quick in the environments I care about: Python and Raspberry Pi.
Step 1: Qt Creator IDE Default Boilerplate.
Once the Qt Creator IDE was up and running, I followed the Qt Quick tutorial to create a bare bones boilerplate Qt Quick application. Even without any changes to the startup boilerplate, it reported error messages complaining of missing modules. Reading the error message, I looked at the output of
apt list qml-module-qtquick* and installed the ones that sound right. (From memory:
qml-module-qtquick2,
qml-module-qtquick-controls2,
qml-module-qtquick-templates2, and
qml-module-qtquick-layouts)
Once the boilerplate successfully launched, I switched languages…
Step 2: PyQt5
The next goal is to get it up and running on Python via PyQt5. The PyQt5 documentation claimed support for QML but the example on the introductory page doesn’t quite line up with the Qt Creator boilerplate code. Looking at the Qt Creator boilerplate main.cpp for reference, I translated the application launch code into main.py. This required
sudo apt install python3-pyqt5.qtquick in addition to the
python3-pyqt5 I already had. (If there are additional dependencies I forgot about, look for them in the output of
apt list python3-pyqt5*)
Once that was done, the application launched successfully on my Ubuntu desktop machine, albeit with visual appearance very different from the C++ version. That’s good enough for now, so I pushed these changes up to Github and switched platforms…
Step 3: Raspberry Pi (Ubuntu mate)
I pulled the project git repository to my Raspberry Pi running Ubuntu Mate and tried to run the project. After installing the required packages, I got stuck. My QML’s
import QtQuick 2.7 failed with error
module "QtQuick" version 2.7 is not installed The obvious implication is that the version of QtQuick in
qml-module-qtquick2 was too old, but I couldn’t figure out how to verify version number is indeed the problem or if it’s a configuration issue elsewhere in the system.
Searching on the web, I found somebody on stackoverflow.com stuck in the same place. As of this writing, no solution had been posted. I wish I was good enough to figure out what’s going on and contribute intelligently to the discussion!
I don’t have a full grasp of what goes on in the world of repositories ran by various Debian-based distributions, but I could see URLs flying by on-screen and I remembered that Ubuntu Mate pulled from different repositories than Raspbian. I switched to Raspbian to give that a shot…
Step 4: Raspberry Pi (Raspbian Stretch)
After repeating the process on the latest Raspbian, the Qt Quick QML test application launches. Hooray! Whether it was some configuration issue or out of date binaries we don’t know yet for sure, but it does run.
That’s the good news. Now the bad news: it launches with the error:
JIT is disabled for QML. Property bindings and animations will be very slow. Visit to learn about possible solutions for your platform.
And indeed, the transition between “First” and “Second” tabs were slow. Looking on the page that it pointed to, it looks like the V4 JavaScript engine used by Qt for QML applications does not have JIT compilation for Raspberry Pi’s ARM chip. That’s a shame.
For now, this excludes Qt Quick as a candidate for writing modern responsive user interfaces for Raspberry Pi applications. If I want to stick with Qt and Python, I’m better off writing Qt interfaces in the old school QWidget style. We’ll keep an eye on this – maybe they’ll add JIT support for Raspberry Pi in the future.
(The source code related to this blog post are publicly available on Github.)
2 thoughts on “Qt Quick with PyQt5 on Raspberry Pi”
It matters much more whether you have 3d acceleration enabled on your Raspberry, or you go with software rendering. Raspberry is one of the best platforms for Qt, including QML, so I think you should look more closely to your performance issues on the platform. Building proper embedded Qt version often involves something like Yocto, not sure how does Stretch work here.
3D acceleration is important for sure, but the biggest problem right now isn’t rendering speed. It’s V4 JavaScript running interpreted instead of compiled, which slow everything down. Even if graphics rendering is fast. | https://newscrewdriver.com/2017/10/17/a-brief-and-unsuccessful-try-at-qt-quick/ | CC-MAIN-2018-30 | refinedweb | 909 | 61.26 |
Toolbox Reference for ISA Server 2006
Microsoft® Internet Security and Acceleration (ISA) Server 2006 includes a Toolbox containing the set of rule elements that you can use when creating ISA Server policies and rules. This document provides background information and descriptions for each Toolbox element.
The Toolbox is accessed from the Firewall Policy node of ISA Server Management. The Toolbox includes these types of rule elements:
ISA Server Network Objects include Networks, Enterprise Networks (Enterprise Edition only) Network Sets, Computers, Address Ranges, Subnets, Computer Sets, URL Sets, Domain Name Sets, Web Listeners, and Server Farms).
In ISA Server®2006 Enterprise Edition, enterprise administrators can create and modify Toolbox rule elements at both the enterprise level (from the Enterprise Policies node in ISA Server Management) and the array level (from the Firewall Policy node in ISA Server Management). Enterprise-level rule elements can be used in both enterprise and array-level policies.
ISA Server®2006 includes a variety of preconfigured protocols that you can use when you create access rules and server publishing rules. You can further expand the set of protocols by using ISA Server Management to create your own.
Protocol Categories
In the Toolbox, protocols are categorized in functional groups. These categories were created to help facilitate selection of the appropriate protocol for your specific scenario. Note that some protocols are listed in more than one category.
For a complete list of protocols used by Microsoft Windows Server System™ products and subcomponents, see "Service overview and network port requirements for the Windows Server System" at Microsoft Help and Support.
Protocol Properties
Predefined and user-defined protocols are comprised of Protocol Type, Direction, Port Range, Protocol Number, ICMP Properties (ICMP protocols only), and Secondary Connections (optional).
Predefined protocols included with ISA Server cannot be modified or deleted.
Protocol Type
Specifies which low-level protocol is used for the protocol definition: TCP, UDP, ICMP, or IP-level.
Direction
ISA Server Domain Name System (DNS) services to reach the published DNS server. When you define protocols for server publishing, you are not required to add the suffix. However, you must define the protocol as inbound.
Port Range
For TCP and UDP, this is a range of ports between 1 and 65,535 that is used for the initial connection.
More than one protocol can be associated with the same port.
If you create a rule denying access to a specific protocol, be sure to include all protocols that use the same port in the exception list. Alternatively, you can create a rule denying any one of the protocols that use the port, and place the deny rule before the access rule in the rules order.
For example, if you create a protocol to be used in a rule that denies access to a virus, do not create an access rule that allows access to everything except the new protocol. Instead, create a rule that denies access to the new protocol. Place this rule before any other access rules that allow protocols on the same ports as the new protocol..
- Secondary connections is an optional property. You cannot define secondary connections for IP-level primary protocols.
Application Filters and Protocols, Web Proxy Filter applies to the Hypertext Transfer Protocol (HTTP). When you disable Web Proxy Filter, Web filters will not apply to traffic that matches this rule. In addition, you can configure a protocol so that an application filter does not apply to the protocol.
The following describes the process:
- The client opens a primary connection to a server on the Internet.
- The ISA Server computer notifies the filter about the connection.
- The filter examines the data that is flowing through the primary connection and determines which secondary connection the client is going to use.
- The filter informs the ISA Server computer to allow that particular secondary connection.
- The ISA Server computer opens the specific port, as indicated by the application filter.
RPC Protocols
When you install ISA Server, incoming and outgoing remote procedure call (RPC) protocol definitions are provided.
Incoming RPC Protocols
When you install ISA Server, two default RPC protocol definitions are provided for incoming requests:
- RPC Server (all interfaces). If this protocol definition is allowed in a server publishing rule, ISA Server will map any inbound RPC requests to the published RPC server. If the universally unique identifier (UUID) is registered on the RPC server, access to the procedure is given. If the UUID is not registered on the RPC server, the request is dropped.
- Exchange RPC server. A list of UUID interfaces used for Microsoft Exchange Server is defined as an RPC protocol definition. You can use this protocol definition in server publishing rules to deny or allow access to specific Exchange functions.
You can create additional RPC protocol definitions. Using the New RPC Protocol Wizard, you can either select UUID interfaces from a list of interfaces available on the RPC server, or you can define the interfaces manually. If you do not specify any interfaces for the incoming RPC protocol definition, server publishing rules that allow this protocol definition do not allow any traffic.
Outgoing RPC Protocols
When you install ISA Server, an outbound RPC protocol is defined for outgoing requests. All. Microsoft Windows® user, a user from a RADIUS namespace, and another user from the SecurID namespace.
ISA Server ISA Server.
Authentication
You can create Web publishing rules, allowing or denying access to a set of computers or to a group of users. If the rule applies specifically to users, ISA Server checks the incoming Web request properties to determine how the user will be authenticated. For example, a Web publishing rule might allow access only to specific users. ISA Server will authenticate the user requesting the object, to determine if the Web publishing rule allows the requesting user access. The user must authenticate, using one of the authentication methods specified for the incoming Web requests.
ISA Server provides a secure, encrypted logon environment for browsers that support Microsoft Windows NT® Challenge/Response authentication, and for other browsers that use Basic authentication. Authentication methods can be set for all IP addresses on the server, or separately for each IP address. File Transfer Protocol (FTP) traffic, which passes through ISA Server 2006.
When a client requests HTTP content, ISA Server sends the request to the Web server. When the Web server returns the object, ISA Server checks the object's MIME type or its file name extension, depending on the header information returned by the Web server. ISA Server determines if a rule applies to a content type that includes the requested.
Preconfigured Content Types
ISA Server is preconfigured with the following content types that can be used in access rules. Preconfigured content types cannot be modified or deleted.
Creating Content Type Sets
In addition to the ISA Server preconfigured content types, you can create your own content type rule element, called a content type set. When you create a content type set, we recommend that you specify the content's MIME type and file name extension. For example, to include all director files in a content type, select the following file name extensions and MIME types:
- .dir
- .dxr
- .dcr
- application/x-director
When you configure a content type set and specify the MIME type, you can use an asterisk (*) as a wildcard character. For example, to include all application types, type application/*. The asterisk wildcard character can be used only with MIME types (and not with file extensions). The asterisk can be specified only once, at the end of the MIME type after the slash mark (/).
For a complete list of Internet Information Services (IIS) default associations, see Appendix A: MIME Types and File Name Extensions.
Link Translation and Content Types
Some published Web sites files and MIME types.
When you create rules, you can apply a schedule to the rule to determine when it is in effect. ISA Server 2006 is preconfigured with the following two schedules:
- Weekends. Permits access at all times on Saturday and Sunday.
- Work hours..
Network objects are used to categorize IP addresses into different types of network entities, which are used to specify network traffic sources and destinations in the access rules, publishing rules, cache rules, traffic chaining rules, and HTTP compression settings that make up your firewall policy.
Note that network rules determine whether there is a relationship between two network entities, and define the type of relationship. Network relationships can be configured for a network address translation (NAT) or route relationship.
The following network objects are created in the Toolbox:
- Networks. A network entity typically corresponds to a physical network. A network always has a network adapter associated with it, and represents one or more IP address range or ranges that can be reached from the associated network adapter.
-.
- Web Listeners. Web listener objects are used to enable an ISA Server network to listen for Web requests on a specific IP address and port. Web listeners can also be enabled to require client authentication for Web requests.
- Server Farms. The server farms object allow you to publish a farm of Web servers, rather than a single Web server. For more information, see "Web Publishing Concepts in ISA Server 2006" at the Microsoft TechNet Web site.
For details about configuring network objects and network rules, see "Network Concepts in ISA Server 2006" at the Microsoft TechNet Web site.
Enterprise-Level Network Objects
In ISA Server 2006 Enterprise Edition, an enterprise-level network is a network defined for the enterprise, rather than for a specific array. Such a network can be used when defining enterprise-level access rules, or included in the definition of an array-level network. The following network objects can also be created at the enterprise level:
- Enterprise Networks
- Network Sets
- Computers
- Address Ranges
- Subnets
- Computer Sets
- URL Sets
- Domain Name Sets
Networks
Networks describe a range of IP addresses. Networks, however, are different from other network objects, in that they also describe physical boundaries. Within these physical boundaries that the network describes, traffic can flow freely. ISA Server policy is not applied within an ISA Server network. A network must always have a network adapter associated with it, and networks cannot have overlapping IP addresses.
When you install ISA Server, the networks described in the following table are created.
Enterprise Networks (Enterprise Edition Only)
When you install ISA Server, the Enterprise networks described in the following table are created at the enterprise level. These networks can be used in enterprise-level and array-level rules.
Network Sets
Network sets are used to define several networks as a single set. This set can be used in firewall policy rules to apply rules to all the networks in the set.
ISA Server 2006 is preconfigured with the following network sets:
- All Networks (including Local Host) . This predefined network set includes all the currently defined ISA Server networks (user-defined and built-in networks).
- All Protected Networks . This predefined network set includes all currently defined ISA Server networks (user-defined and built-in networks), except for the built-in External network.
There are two types of network sets, Exclude and Include. Exclude network sets are defined by selecting a set of networks excluded from the network set. The network set is actually comprised of all the networks that are not selected. Include network sets are defined by selecting the networks that are included in the network set.
Computers
A computer network object defines a single computer IP address as a network element that can be used in access and policy rules. Note that a computer name cannot be used.
Address Ranges.
Subnets.
Computer Sets
- Computer sets define a collection of computers, IP address ranges, or subnets as a single network object that can be used in access and policy rules. When you install ISA Server, the following computer sets are created:
- Anywhere. A predefined computer set of all IP address ranges.
- IPsec Remote Gateways. A predefined computer set that includes the IP addresses of Internet Protocol security (IPsec) remote VPN gateways that are configured using the Site-to-Site VPN Wizard.
- Remote Management Computers. A predefined computer set that includes computers allowed to manage ISA Server remotely. It should be modified to include IP addresses of all computers that can manage ISA Server remotely. If ISA Server is installed remotely within an active Remote Desktop session, the IP address of the remote computer is added automatically to this computer set.
- Array Servers. (Enterprise Edition only.) A predefined computer set used in a system policy rule that allows traffic between array members. For each array, this computer set includes the IP addresses of array members. Computers are added during installation. If you subsequently change the address of an array member, be sure to update this computer set accordingly.
- Managed ISA Server Computers. (Enterprise Edition only.) A predefined computer set that includes computers allowed to connect to this array's Configuration Storage server. It should be modified to include IP addresses of all computers that will connect to the Configuration Storage server.
When you install ISA Server Enterprise Edition, the following enterprise-level computer sets are created.
- Anywhere. A predefined computer set of all IP address ranges.
- Enterprise Remote Management Computers. A computer set that includes computers allowed to remotely manage all ISA Server computers in the enterprise. The Enterprise Remote Management Computers computer set can also be used when creating array-level rules.
- Replicate Configuration Storage servers. A predefined computer set that includes all Configuration Storage server computers that are replicated with the local Configuration Storage server.
URL Sets
Uniform Resource Locator (URL) sets specify one or more URLs grouped together to form a set. URL sets can be used in access rules to allow or deny access to specified Web sites.
You can create a URL set, and then use it in access rules to allow or deny access to Web sites specified in the set. When ISA Server processes a rule that applies to a URL set, the URL set element of the rule is only processed for Web traffic requests. Protocols include HTTP, HTTPS, or FTP over HTTP. If a client request uses another protocol, ISA Server ignores the URL set when processing the rule. For example, if a rule has both a computer set and a URL set specified as destination criteria, only the computer set will be evaluated in the rule. The URL set will be ignored.
You can specify one or more URLs in URL format:
In the host part of the name, you can use an asterisk (*) wildcard character to specify a set of computers. For example, to specify all computers in the Microsoft.com domain, specify *.microsoft.com.
In the path part of the name, you can specify an asterisk wildcard character as part of the path, but only at the end. For example:
-* is acceptable.
-*/sales is not acceptable.
You cannot specify a URL set as an IP address.
Processing URL Sets
ISA Server processes rules that apply to URL sets only for Web traffic (for client requests for HTTP or FTP over HTTP). When a client uses any other protocol, ISA Server does not process rules that apply only to a URL set.
Note the following behavior in matching requests with rules containing URL sets:
- Only the host name and path are considered in a request.
- The protocol part of the URL is stripped from requests and ignored.
- You can also specify a path. Wildcard characters can be used in the path, but only at the end. For example,* is acceptable. However,*/sales is not acceptable.
- Although the URL can include a specific port number, ISA Server ignores that port number when processing the rule. Any port number specified is stripped from requests and ignored.
- If a request includes a question mark (?), the question mark and everything following it are stripped from the request before matching.
- When matching, the host and path names are not case-sensitive. For example, this means that folderA and foldera would be considered the same path.
- For HTTP or FTP over HTTP, when the URL is specified in a request without a path, it will match any path. For example, or a.com is equivalent to*.
- For HTTPS traffic, URL sets are only processed if the URL does not have a path specified, for example, or a.com. If the URL has a path specified, for example a slash mark (/), it is ignored for HTTPS traffic.
- When ISA Server checks the URL sets configured for a rule, text after a question mark (?) is ignored. URLs with a ?, which are included in a URL set, are ignored.
Possible protocols are HTTP, HTTPS, and FTP. However, when ISA Server processes a rule that applies to a URL set, the protocol specified is ignored—only the host name and path are considered.
Name Resolution (URL Sets are no rule criteria that prevent.
URL Set Mapping
Some URL set mapping examples are as follows:
- For a URL set that includes the URL, requests for and for will be matched, because protocol and port are stripped.
- For a URL set that includes the URL, requests for will be matched, as will requests for. For example, is the equivalent of*. The exception is for HTTPS requests, which will not be processed because a path is specified.
- For a URL set that includes the URL, requests for will be matched. But requests for will not be matched. In such an entry, requests are not matched to the tree following "a."
- For a URL set that includes the URL, the question mark and everything following will be stripped from requests. If this URL set was specified in a deny rule, and a request arrives for, the request is stripped to. It would be allowed because it does not match the URL set specified in the deny rule. To block such a request, you should specify in the URL set.
- For a URL set that includes the URL a.com, HTTPS requests will be matched, because no path is specified.
- For a URL set that includes the URL b.com/, HTTPS requests will not be matched, because a path (/) is specified.
Domain Name Sets
Domain name sets define one or more domain names as a single set, so that you can apply firewall policy to the specified domains. When you install ISA Server, the following domain name sets are created:
- Microsoft Error Reporting Sites. A predefined domain name set used to allow error reporting.
- System Policy Allowed Sites. A predefined domain name set used to allow access to trusted sites for maintenance and management.
- Enterprise Configuration Storage Servers. (Enterprise Edition only.) A predefined domain name set for the Configuration Storage server used by the ISA Server computer.
- Microsoft Update Domain Name Set. A predefined domain name set of all Microsoft update servers. This domain name set is used in the ISA Server Microsoft Update Cache Rule properties.
Specifying Domain Names
When you apply a rule to a domain name set, ISA Server checks whether the request matches the specified domain name set. ISA Server checks the exact name that you specified, including port numbers. For example, consider a Web publishing rule that allows access to a domain name set that includes fabrikam.put:1111. Requests to fabrikam.put will be denied. Requests to fabrikam.put will be allowed only if the domain name set is changed to include fabrikam.put. For this reason, do not specify a port number in a domain name set.
When creating a domain name set, note the following:
- When you specify a domain name, specify the computer name using the fully qualified domain name (FQDN). For example, computer_name.microsoft.com, and not \\computer_name. You cannot specify a domain name set as an IP address. When specifying the domain name, you can use an asterisk (*) to specify a set of computers. For example, to specify all computers in the Microsoft.com domain, type the domain name as *.microsoft.com. Note that the asterisk can appear only at the start of the domain name, and can be specified only once in the name.
- When you create a domain with a wildcard character, such as *.microsoft.com, this only includes host computers at the domain, for example,. Note that if the domain name points to a host, *.microsoft.com will have no effect on the URL.
- We recommend that you enter the domain name as it is returned by the Domain Name System (DNS). If you specify a dot at the end of a domain name, a request for the domain name (without a dot) may not be matched as required.
- When matching rules, the domain name is not case-sensitive.
Name Resolution is no rule criteria that prevents.
Web Listeners
When you create a Web publishing rule, you specify a Web listener to be used when applying the rule. The Web listener properties determine:
- Type of connections the Web listener will establish with clients, either Secure Sockets Layer (SSL) or HTTP.
- The ISA Server networks, and which IP addresses and ports on the specified networks, will listen for Web requests.
- The SSL server certificate that will be used to authenticate the client connection (if SSL is selected).
- Which authentication method will be used and when authentication is required.
- The method used by clients to authenticate to ISA Server.
- The method used by ISA Server to validate client credentials.
Web listeners can be used by more than one Web publishing rule.
Web Listener Network (IP Address) Selection
The Web listener network, or networks, that you select depend on which network clients will use to connect to the published Web server. For example, if the Web site you are publishing allows client requests from the Internet (External network), you should select the External network for the Web listener. By selecting the External network, you are selecting the IP addresses on the ISA Server computer that are associated with the external network adapter. If you do not limit the IP addresses, all IP addresses associated with the selected network adapter will be included in the listener configuration.
Web listeners are used by a Web publishing rule. The rule specifies source network objects in addition to specifying a Web listener. The network objects specified for the Web publishing rule must also be specified for the Web listener.
Selecting SSL Server Certificates
Each Web listener can be used for one or more Web sites. However, ISA Server limits one certificate per IP address. If all the Web sites use the same certificate, you can publish using the same Web listener. However, if different certificates are required, you must do one of the following:
- Install a wildcard certificate.
- Add an IP address to the listening network adapter on the ISA Server computer (or array in ISA Server Enterprise Edition) for each SSL-enabled Web site.
For example, you want to publish three SSL Web sites:,, and. All three sites are registered in a public DNS, and resolve to the same IP address. You must install a wildcard certificate for *.treyresearch.net to publish these sites. Alternatively, you could add more IP addresses.
In ISA Server 2004, wildcard certificates are supported only on the ISA Server computer. In HTTPS-to-HTTPS bridging, you cannot use wildcard certificates to authenticate the back-end Web server to ISA Server. In ISA Server 2006, wildcard certificates are supported on both the ISA Server computer and the back-end Web server.
For more information about wildcard certificates, see "Publishing Multiple Web Sites using a Wildcard Certificate in ISA Server 2006" at the Microsoft TechNet Web site. Most of the procedures in this document are applicable for ISA Server 2006.
Limiting Concurrent Connections
By limiting the number of connections allowed simultaneously to the ISA Server computer, you can prevent attacks that overwhelm the system's resources. This is particularly useful when publishing servers. You can limit the number of computers that connect, while allowing for specific clients to continue connecting, even when the limit is surpassed.
Port Specification
By default, ISA Server listens on port 80 for HTTP requests. If, however, connecting clients are expected to use a different port, you should change the port number accordingly. You can also enable the Web listener to listen for SSL requests on the default port 443. If you choose SSL, an appropriate certificate must first be installed on the ISA Server computer. You must select a server certificate to be used by the Web listener so that the ISA Server computer can authenticate itself to the client.
Server Farms
Web applications and sites are often hosted by a Web farm, consisting of two or more mirrored Web servers. A server farm (also referred to as a Web farm) defines an existing load balanced cluster as an ISA Server server farm that can be used for publishing load balanced Web applications. When you create a server farm, you specify the computer name or IP address of each server in the farm.
Server Farm Load Balancing Mechanism
In many scenarios, for load balancing to be effective, affinity must be maintained between the client and the Web server that receives and responds to the client's request. Otherwise, a series of requests from the client and responses from the Web farm will be handled by different Web servers, ignoring the context of the requests. For example, Outlook Web Access is an application that requires client affinity, because the Outlook Web Access server maintains a context for the connected client.
The need for affinity is also demonstrated in a Web shopping scenario, where a client sets up a shopping cart on a Web server. If affinity is not maintained, at some point in the client's session, the client's requests may be directed to another Web server that is unaware of the shopping cart.
When you apply a rule to a server farm, you can also configure if the load balancing mechanism should be cookie based or source-IP based.
We recommend that you use session affinity when possible, because it provides more reliable client affinity when a Web server is restarted. This is sometimes referred to as client stickiness. It also works better in a situation where you are draining a Web server. Session affinity should be used for load balancing Outlook Web Access or Microsoft Windows SharePoint® Services access, both of which use Microsoft Internet Explorer®, and therefore support HTTP cookies.
IP address-based affinity has an advantage over session affinity in that it supports clients that are not fully compliant with HTTP 1.1 (clients that do not support HTTP cookies), such as some mobile devices. IP address-based affinity must also be used in a scenario where you are load balancing RPC over HTTP Outlook access. Outlook does not work with HTTP cookies, and therefore cannot use session affinity.
Note that if you are publishing a server farm with ISA Server 2006 located behind another firewall, you must either use session affinity, or use IP address affinity and verify that the front-end firewall is configured to pass the original client's IP address to ISA Server.
Server Farm Connectivity Verifiers
When you create a server farm, ISA Server creates a connectivity verifier for each Web server. Note that if your Web servers use a port other than port 80, specify that port on the server farm properties Connectivity Verification tab. You can view connectivity verifier status for the server farm in the Monitoring node, on the Connectivity Verifiers tab.
Draining a Server Farm
ISA Server provides a Drain option allowing you to specify that a server in the farm should temporarily stop accepting new connections. When you are ready for the server to begin accepting connections again, the Resume option is available.
Note that Drain and Resume are only active after you click the Apply button on the Apply Changes bar. When you drain a server, it stops accepting new connections. However, existing connections are not dropped.

Hi Jeremy!
I've tried those packages:

and I've installed them succesfully through dpkg -i *.deb. Afrer installing nvidia drivers recompiled succesfully.
But after reboot kernel during booting in text mode several time screen blinks and after switching to graphics mode its probably set wrong graphics mode because all screen messed up and X session not apperared properly... :-( It's doesn't hang, I could switch to text mode and back (via Ctrl-Alt-F1 Ctrl-Alt-F7), but I can't login to the system.
So I couldn't check touchpad without X.
Hi Øyvind,
Actually I don't think it is. The touchpad on the Dell Latitude 6510 is not recognized as such but as a PS/2 Generic Mouse and I do not have a TouchPad section at all (see screenshot attached)
BR,
Steven
I've attached as much information as I could think of. please tell me if you need more/other information and how to retrieve it.
Thanks,
Steven
is i386 a relevant tag? I'm having the same issue on a 64-bit Ubuntu install.
Mine is 64bit too
I have the same problem on a Hercules EC-800 (very cheap 8" notebook). Kernel 2.6.32-24-generic #39-Ubuntu (installed from xubuntu "lucid" 10.04). Ressources on this "machine" are low (20 GB hard drive, etc.), so testing is hard.

Hi,
I actually want to *deactivate* the touchpad. I prefer working with the pointer in the middle of the keyboard. But even though Remco's workaround gets the touchpad recognized I cannot deactivate it and it still interferes with typing.

if you want to enable/disable the touchpad
Thanks Jordi.
But that also disables the pointer in the middle of the keyboard... Is there a way to identify the touchpad and the keyboard pointer as 2 different devices and then only disable the touchpad ?

Steven, no, both are physically in the same cable
Well Jordi it actually helps me a lot already: when I have an external mouse plugged in, I simply run your script (using bash though ;) ) and voilà! no more typing freakness :D
It remains of course when I don't have an external mouse.
So: thanks :)
Steven
Steven, I have Win+F7 binded to that script, that way i can easily enable/disable the touchpad
#550625 addresses a slightly different type of hardware; the touchpad in question is identified as Product=0005 at /proc/bus/
However, the root cause appears to be described at https:/.
The hardware detection used by the DELL patch in alps.c is:
{ { 0x73, 0x02, 0x64 }, 0x00, 0x00, ALPS_EC_PROTO }, /* Dell E2 series multitouch */
ALPS_EC_PROTO denotes a device memory access protocol used by the pads for initialization. It seems that this issue might affect all DELL E2 notebooks.
Thanks Simon! at least we know someone's working on this bug. My primary issue is that the touchpad does not turn off during typing. Hope to see a solution/workaround soon.
Thanks Jordi for the script. I will use your script as a workaround till a fix is found. Just tested it works great.
Jordi, thanks for the script! After little modifications to xinput for 9.10 ubuntu the script works well. I don't know why xinput have such different syntax beetwen 9.10 and 10.04... I attached script for enable/disable touchpad for 9.10.
I can confirm that this problem also appear for the Dell E5510 laptops.
I agree with Simon Dierl that this is not the same issue as #550625 (I also get Product 0x1) even though some persons with this problem has posted at that thread.
Many thanks for the sh script!!! It is really useful!!!
I have Dell E5510 with ubuntu 10.04 and I can confirm that I have exactly the same issues with my touchpad.
Regarding the bug: It is interesting that touchpad is actually recognised by old kernel versions, see
http://
It would be really lovely is this touchpad problem is solved in new kernel versions. Meanwhile, I am using external mouse and the toggleps2.sh with the shortcut (I also changed zsh to bash int eh script).
Another question - do you know actually how to make the SD card reader working on E5510?
Many thanks!
Hi,
I have E6410 and Ubuntu 10.10 kernel 2.6.35-24-generic #42-Ubuntu SMP Thu Dec 2 02:41:37 UTC 2010 x86_64 GNU/Linux
So far I have found this:
https:/
I assume it is the best option so far. I am totally new with patching. Could anyone tell me if this patch will work in Ubuntu ?
If yes, how to apply this patch (step by step guide is preferred ;-) ?
Cheers
Grzesiek
I've attached a sloppy python program inspired by Jordi's handy script. It disables the touchpad as soon as it detects keyboard activity, then a fraction of a second after the end of the keyboard activity, it re-enables the touchpad. I have an E6510 running Ubuntu 10.10 on x64, and I run the script like this:
$ sudo ./keyboarddetec
If you're running on x86, you might need to tweak the line containing "calcsize". It could be cleaned up to figure out automatically which of the event* entries to use.
Graham
Here's a refined version of the script.
- Auto detect keyboard and trackpoint devices.
- Auto detect 32-bit/64-bit processors.
- Don't disable trackpoint for modifier keys.
The last one is important to allow modifier keys to be used in conjunction with the mouse, e.g. "control select".

Great! I dump a lot of email lists, including linux-input, on my server
and only periodically check them. I just saw your three-part

Good to know but I'm unclear how to proceed. Back when, I put in a
sysfs debug interface that a user could run to capture the physical
coordinates of the edges in order to tune the X edge properties. I
could take your patches, add the debug and release a new dkms.

I agree there are a lot of similarities but some differences as well.
For example, V3 uses byte 4 for x/y coordinates and byte 3 for buttons;
V4 uses byte 3 for x/y coordinates and byte 4 for buttons. This could
take a little bit of time to refactor. I'm backed up on several other
projects so I need to move on.

Just for the record, I'm on a Dell Latitude e6430u running Ubuntu 12.10 (Quantal) and this issue affects me.
Hi, what's the lead time from fixes getting committed until they arrive via the usual package updates?
I have an old Dell Inspiron 8200 that I'm trying to setup and the touchpad doesn't work at all, I think it's detected as PS2 Mouse.
I think this will probably fix it or should I submit a separate bug report with all the info?
Thanks for all the work on this.
@matt
I noticed that Kevin's patches were accepted for the next 3.7 kernel release.
I also noticed that a fedora maintainer backported Kevin's patches to the next Fedora release. See https:/
I have not seen any activity by Ubuntu maintainers to backport the patches, so I doubt they will be integrated into the Ubuntu train any time soon.
You can test it yourself by installing the psmouse-

Hi Dave, thanks also for all of your work.
How would, or is it ever likely, that this fix will make it into Quantal?
There's got to be a huge number of Ubuntu users out there with Dell laptops that could do with this functionality.
Is there anything we can do to petition the Ubuntu maintainers on this?
Thanks again.

Now I can see the Alps Touchpad and scrolling does work!
wolfgang@ GlidePoint id=13 [slave pointer (2)]
First of all: thanks for the work guys
I am on Dell Latitude XT
Alps hardware: touchpad, 4 buttons, 1 stick
Touchpad is detected as PS2 mouse, synapticts not loaded.
Touchpad works (tapping/moving), but not very sensitive cq. delays, buttons an stick work
The insensitivity / delays made me look for changing the setup.
And that made me aware of the synaptics issue.
(I never use scrolling so had not noticed anything missing ...).
Installed Os's:
wheezy 3.2.0-4-amd64 / xubuntu 3.2.0-40-generic / XP .
Downloaded psmouse-alps-1.3 from http://
Unfortunately, there is no support for Dell Latitude XT.
Found an old mail exchange (2009) from Dmitry Torokhov.
This gave me a clue as what to try.
Added the following line to alps_model_data[]
{ { 0x73, 0x00, 0x14 }, 0x00, ALPS_PROTO_V2, 0xf8, 0xf8, ALPS_DUALPOINT | ALPS_FW_BK_2 }, /* Dell Latitude XT */
resulting dmesg:: F5 report: 73 00 14
input: DualPoint Stick as /devices/
input: AlpsPS/2 ALPS DualPoint TouchPad as /devices/
Touchpad recognized, tapping works, scrolling works, buttons work.
The stick however goes haywire, sending random click events when touched.
This is in both xubuntu and wheezy
In wheezy I had to enable tapping, in xubuntu tapping worked 'out of the box'
My questions:
What is the status of Latitude XT support in alps.c ?
Can I help ?
Where to put these questions ?
I am pretty comfortable with linux and C
I also have win XP with latest Dell Alps driver on this laptop
(must say, I am not a happy windows hacker but can do ...)
Lee
@libondom-0
My guess is this is another mutation of the ALPS touchpad. It clearly is a new signature, which you added, which indicates new behavior: the trackstick. There have been several new significant behaviors added to the alps driver ("Rushmore" and "Dolphin").
The best I can recommend, not having this touchpad (and it's an n:m mapping between Dell system and Alps touchpad), is to add code to the driver to dump the trackstick changes and then try to reverse engineer what the movement codes actually mean. See the alps_process_
BTW, I experienced similar upheaval in the late 1980's as a customer to a company called Newbridge. Its staff was turning over so quickly that relative newbies were the sole support for some of their hardware and just hacked it up to get it to work regardless of documentation or compatibility. They released M$ drivers to support the new firmware but Unix boxes (we were a SUN shop) were left hanging. Newbridge and SUN no longer exist; I think this bodes poorly for ALPS.
Dave
Hi Dave
Glad to see you are monitoring.
What/where is the best way to communicate about this?
The problem at hand:
It comes down to reverse engineering then.
The mail exchange from Dmitry Torokhov I mentioned was about Latitude XT
So some (reverse) engineering has been going on.
I have read some posts of people doing this with Virtualbox.
Must go backtrack a bit here.
Do you have any idea if there is anything of the sort going on upstream?
I do not want to invent the (mouse)wheel, but if nothing is happening,
I will have a go.
Looks a bit like a can of worms to me, but hey, I believe I like to make things work.
Would appreciate suggestions/tips as to how to go about.
Like using real or virtual XP
I use kvm/qemu here, and touchpad support would have to be added I think.
And then, how much do I have to know about win XP?
will keep posting here for now
Lee
On second thought, do I need XP?
The touchpad is already recognized an handled by synaptics.
So all can be done in alps.c no?
Reverse engineer the event readings from 'cat /dev/input/mouseN'
On the right track here?
Lee
on third thought
>>add code to the driver to dump trackstick changes'
i am there now
bit slow in pickin up ...

Response to comments 348, 349, 350:
The easiest, and I mean *easiest*, way is to hack alps.c for the raw input from the touchpad and then "xinput setprop" to tune the X11 cooked input.
For brand-new alps touchpads that don't adhere to any of the known protocols, this is not sufficient and one needs to reverse engineer the Windows driver behavior. Seth Forshee showed us the way and then Ben Garami figured out the the new extensions. I seriously doubt this will be the case for you.
Use Virtualbox or Qemu to create a guest OS. I used Vista. Seth showed how to patch the I/O layer to dump the bytes going between the guest driver and the hardware. The catch is that the new alps drivers check the BIOS ACPI DSDT tables to make sure it's an ALPS hardware module; if not it drops into 3-byte PS2 mode. Therefore the virtual ACPI DSDT table must be updated to use the Hardware ID (HID) for the alps hardware model (taken from the real ACPI DSDT table.) If this sounds a little complicated, it is. Make sure you install the Alps driver into the guest OS!
In the alps.sh from the 1.3 DLKM, there are some helper routines to get the real DSDT and patch the qemu acpi-dsdt.dsl table for the correct HID.
There is another way to reverse engineer an ALPS touchpad, discovered by Kevin Cernekee but it's not totally reliable. It worked for him, and cleaned up the E6430 code a good deal. Email Kevin directly for how to do it.

The code version from comment #356 fixed my problems mentioned in comment #352. It works with Raring on the 3.8 kernel. I'm very happy because reverting to the supersensitive, nonscrolling touchpad I had before you wrote this driver was pretty unbearable. Thanks again for all of your work on this.
When you say it has been accepted to the linux kernel, do you mean to say that at some point this will work out-of-the-box without installing the driver with DKMS?
On Fujitsu LB AH532, after installing the driver I have both psmouse and ALPS touchpad active. I have only touchpad. Vertical scroll works in very narrow area on the right of the touchpad. Mouse and Touchpad have duplicate settings in the "Mouse and Touchpad" dialog: pointer acceleration and sensitivity. Is it intentional or anything wrong with my system?

I have Ubuntu 12.04 with 3.5.0 kernel and xserver-
I am running Ubuntu 13.04 on a Dell Latitude E6430u, and my touchpad is recognized by default. Two-finger scrolling works. Pinch-to-zoom also works in e.g. Eye of GNOME (but not in Firefox/Chromium). It's great that the driver has been backported.
Now that Linux 3.9 is making its way into circulation, let's summarize the reported issues to date:
1) No Dolphin V2 support. Still need to borrow hardware to fully understand the report format and make edge scrolling work without excessive pressure. I believe we have a good init sequence.
2) Resync errors:
[1766509.702598] psmouse serio1: DualPoint TouchPad at isa0060/
[1766509.712794] psmouse serio1: DualPoint TouchPad at isa0060/

[1766509.753533] psmouse serio1: DualPoint TouchPad at isa0060/
I see these pop up in dmesg every week or two; they run for maybe a minute or so and then vanish, with no obvious ill effects. Not sure how to reproduce them.
3) Click-and-drag (e.g. selecting text in an xterm) suddenly quits working. I've only seen this happen once. Unloading and reloading psmouse.ko fixed it. This problem mystifies me because when I ran xev, I still saw all of the proper events coming from the input device. So maybe it was caused by something higher in the stack.
4) Tap-to-click is broken on Rushmore[1]. Root cause: when transitioning from Linux 3.8 (touchpad detected as generic PS/2 mouse) to 3.9 (touchpad detected as an ALPS touchpad), tap-to-click in the pointer settings may need to be enabled by hand. If the touchpad is detected as a generic PS/2 mouse, tap-to-click will work regardless of this setting.
5) Pointer jumps all over the screen after suspend/resume on a Rushmore touchpad. Seen once, cannot reproduce.
6) "Noisy" X/Y values on Rushmore[2]. Reporter is investigating whether this shows up on other drivers. Three possibilities include: i) it's noisy everywhere, even in Windows; ii) the input data is noisy, and the driver needs to clean it up; or iii) the other drivers get "clean" report data but we're using a bad init sequence so our report data is sketchy.
Any hints on reproducing #2, #3, or #5 would be appreciated.

Hi all,
I have a Dell Vostro 3360 with a 'Dolphin V2' touchpad, running linux 3.10-rc1 (latest from git).
I have been using the psmouse-
I had to make a few changes to build it against the latest kernel tree though, and instead of doing the DKMS thing I just copied alps.c into drivers/
Is it possible to get this V2 support mainlined? This patch works fine for me, but I'd be happy to provide any data/have a go at mild hacking required to fix other issues (edge scrolling) if that is needed to get the driver upstream.
The work so far is great, thanks to everyone involved.
Cheers!
Chris
On Dells this has been worked on and at bug 1089413, you can find fix status for different Ubuntu versions there.
Hi,
It has been fixed for 'Dolphin V1' touchpads - the driver is upstream so they are fine.
The problem is that 'Doplhin V2' touchpads don't yet work - although a driver has been written (it's in the DKMS module and works great), it hasn't yet been pushed to the mainline kernel.
It would be great if 'V2' support was mainlined too.
Apologies, I didn't really say this very clearly in my first comment.
Cheers!
Also affects:
201205-11042 Dell Precision M6700 (AlpsPS/2 ALPS DualPoint Touchpad)

http://
Bráulio, which release are you using?
I installed the package on my Fujitsu Lifebook and it is almost unusable - the touchpad fails to detect small touches (i.e. detects only a flat finger, not the fingertip); the x/y values are way off (y movement much faster than x, which is very sluggish). Multitouch features work though and ubuntu detects the touchpad as such.
Karol Szkudlare.
Thank You, Christopher for reminding!
I had the same problem (see above): For me it's solved since Ubuntu 13.10.
I use now kernel 3.11.0-15.
Touchpad works fine. In settings i can choose between
- Scroll with 2 fingers and
- natural scroll
=> both works!
=> for me the bug is fixed!
I'm using the psmouse driver on a Dell Inspiron 17R SE and it makes the touchpad work as an actual touchpad and not just a mouse. However, I'm experiencing a significant amount of backlash. By this, I mean that when reversing the direction of movement the cursor will remain still for some time before it actually moves again. The behavior is very similar to the mechanical concept of backlash, which is nicely explained in this Wikipedia article:
http://
Could this be a flaw in the driver or in some other part of the software system? Is it just a property of my hardware? I have noticed the exact same behavior on a Fujitsu Lifebook with an ALPS touchpad that also works with this driver.

This extension provides a validator class that enables to define an AR class attribute to be containing a valid class name. This is useful in occasions such as when you have a class file that refers to other models in your system. For example, 'views counter', 'like functionality' and more... .
Usage ¶
- This extension is designed as an external validation class. To use it, insert snippet like the one demonstrated below to the relevant AR class 'rules' method:
public function rules() { // NOTE: you should only define rules for those attributes that // will receive user inputs. return array( // more rules here... array('model_name', 'PcClassExistsValidator'), // more rules here... ); }
- In order to change its configuration options, pass them as parameters in the array shown above (in rules()).
- You have to make sure that each class that its name is supposed to be the value of the property you want to 'validate' using this validator class, has been 'imported' by Yii before the validation takes place. This typically means updating the 'import' attribute of CWebApplication in config/main.php config file in advance. I didn't find any slicker solution that will achieve "presence" of the class names in PHP's global namespace prior to running the validation process (if you have an idea please let me know).
- Validator will output log messages (using Yii::log) in case of errors for easy debugging (if you're using the log facility).
Configuration options: ¶
The following are the class public attributes via which the configuration is passed, along with their default values:
/* @var bool $allowEmpty Whether the attribute is allowed to be empty. */ public $allowEmpty = false; /* @var string $emptyMessage the message to be displayed if an empty value is validated while 'allowEmpty' is false */ public $emptyMessage = "{attribute} cannot be blank"; public $errorMessage = " is not a valid class name. Make sure to configure config/main.php 'import' section to load all relevant classes.";

So here I am, happily hacking along at my first Iliad web application, when I get all fancy and want to set it up on a public server.
Heh ... a bit of fiddling required, since neither "my" Iliad nor "my" gst are out of the box anymore, but applying two patches is not too hard work.
Now I have everything ready: patched gst starts the REPL, gst-package builds OnlineTester.star, gst-load -viI ot.im OnlineTester ... throws an error, while starting Swazoo. Ah, yes, I think quickly, that port is already in use here. So I change, rinse and repeat ... and the error is still there. A FileError? When opening a socket. What?

Today I released an updated ScalaTest-1.5-SNAPSHOT that includes several enhancements, including two new style traits, PropSpec and FreeSpec. The snapshot works with Scala 2.8. You can download the snapshot release via the scala-tools.org Maven repository with:
PropSpec
FreeSpec
Or you can just grab the jar file from:
I put the Scaladoc for this snapshot release up here:
PropSpec allows you to create a suite of property-based tests. It works the same as a FunSuite, but instead of test you write property, and instead of testsFor you write propertiesFor.
FunSuite
test
property
testsFor
propertiesFor
PropSpec supports both ScalaCheck and ScalaTest property styles (as well as any other property style you may wish to use it with.) If you want to write properties in the ScalaCheck style, mix Checkers into your PropSpec. If you want to write them in the ScalaTest style, mix in PropertyChecks. Here's an example that uses both generator- and table-driven property checks:
Checkers
PropertyChecks
import org.scalatest.PropSpec
import org.scalatest.prop.PropertyChecks
import org.scalatest.matchers.ShouldMatchers
class FractionSpec extends PropSpec with PropertyChecks with ShouldMatchers {
property("Fraction constructor normalizes numerator and denominator") {
forAll {
}
}
}
property("Fraction constructor throws IAE on bad data.") {
val invalidCombos =
Table(
("n", "d"),
(Integer.MIN_VALUE, Integer.MIN_VALUE),
(1, Integer.MIN_VALUE),
(Integer.MIN_VALUE, 1),
(Integer.MIN_VALUE, 0),
(1, 0)
)
forAll (invalidCombos) { (n: Int, d: Int) =>
evaluating {
new Fraction(n, d)
} should produce [IllegalArgumentException]
}
}
}
For more information, see the Scaladoc documentation for PropSpec and my earlier post, ScalaTest Property Checks Preview. Trait PropSpec is the last piece of ScalaTest's new support for property-based testing described in that previous post.
Note: Trait PropSpec is in part inspired by class org.scalacheck.Properties, designed by Rickard Nilsson for the ScalaCheck test framework.
The other new style trait introduced in today's snapshot release is FreeSpec. Whereas ScalaTest's other specification-style traits facilitate writing text with certain grammatical structures using words like "when," "should," and "can," FreeSpec allows you to structure the text of your specification however you wish. You write a test in a FreeSpec with a string followed by in and a block of test code, just as you do in WordSpec and FlatSpec:
in
WordSpec
FlatSpec
"should pop values in last-in-first-out order" in {
// ...
}
You can surround tests with description clauses composed of a string, a dash character (-), and a block. Here's an example:
-
"A Stack" - {
"should pop values in last-in-first-out order" in {
// ...
}
}
You can nest description clauses inside description clauses to any number of levels. Here's an example:
import org.scalatest.FreeSpec
class StackSpec extends FreeSpec {
"A Stack" - {
"whenever it is empty" - {
"certainly ought to" - {
"be empty" in {
// ...
}
"complain on peek" in {
// ...
}
"complain on pop" in {
// ...
}
}
}
"but when full, by contrast, must" - {
"be full" in {
// ...
}
"complain on push" in {
// ...
}
}
}
}
When run in the interpreter, you'd see:
scala> (new StackSpec).execute()
StackSpec:
A Stack
whenever it is empty
certainly ought to
- be empty
- complain on peek
- complain on pop
but when full, by contrast, must
- be full
- complain on push
Another use case for FreeSpec is writing specification-style test suites in a language other than English, as demonstrated here:
import org.scalatest.FreeSpec
class ComputerRoomRulesSpec extends FreeSpec {
"Achtung!" - {
"Alle touristen und non-technischen lookenpeepers!" - {
"Das machine is nicht fuer fingerpoken und mittengrabben." in {
// ...
}
"Is easy" - {
"schnappen der springenwerk" in {
// ...
}
"blowenfusen" in {
// ...
}
"und poppencorken mit spitzen sparken." in {
// ...
}
}
"Das machine is diggen by experten only." in {
// ...
}
"Is nicht fuer gerwerken by das dummkopfen." in {
// ...
}
"Das rubbernecken sightseeren keepen das cottenpicken hands in das pockets." in {
// ...
}
"Relaxen und watchen das blinkenlights." in {
// ...
}
}
}
}
ComputerRoomRulesSpec
scala> (new ComputerRoomRulesSpec).execute()
ComputerRoomRulesSpec:
Achtung!
Alle touristen und non-technischen lookenpeepers!
- Das machine is nicht fuer fuer gerwerken by das dummkopfen.
- Das rubbernecken sightseeren keepen das cottenpicken hands in das pockets.
- Relaxen und watchen das blinkenlights.
The FreeSpec concept first saw light of day way back in ScalaTest 0.9.4 under the name SpecDasher. I released it already deprecated with a warning that I would remove it in 0.9.5, which I did. I only released it because I'd shown it in Programming in Scala, which had already gone to the printer. I wanted all the code in the book to work for the version of ScalaTest mentioned in the book. I removed it in 0.9.5 because I wasn't convinced I had figured out the best way to do it, and even if I figured that out, I only planned to add it if users actually convinced me it would be useful to them.
SpecDasher
Eric Torreborre's specs framework always had a >> operator that provided a similar nesting ability to FreeSpec's dash character, but in the specs case >> was an alias for in, which meant tests (called "examples" in specs) were being nested not specification text (and you still could put a should on top). The specsy project by Esko Luontola came closer to the concept, and in fact Esko wrote a blog post about the troubles with pre-defined words, Choice of Words in Testing Frameworks. Over time I did get input from users that they would find value in this kind of trait, for example, in this scalatest-users discussion started by Sukant Hajra. And I got the opposite feedback, in a way, of seeing someone use trait Spec and completely ignoring the guiding structure. So now FreeSpec is here.
>>
should
Spec
Another user feedback that I got over time is that users really liked the formatted output of the BDD-style (Behavior-Driven-Development-style) traits, and wanted to see the same thing in the TDD-style (Test-Driven-Development-style) traits. I did things that way originally because making the output of running a test suite a more useful artifact was a push from the BDD folks. But the users gave me this feedback, so now even when you run a Suite, FunSuite, JUnitSuite, JUnit3Suite, or a TestNGSuite, you get nicely formatted output. For example, given this FunSuite:
Suite
JUnitSuite
JUnit3Suite
TestNGSuite
import org.scalatest.FunSuite
class MySuite extends FunSuite {
test("addition") {
val sum = 1 + 1
assert(sum === 2)
assert(sum + 2 === 4)
}
test("subtraction") {
val diff = 4 - 1
assert(diff === 3)
assert(diff - 2 === 1)
}
}
Running from the interpreter in ScalaTest 1.3 gives you:
scala> (new MySuite).execute()
Test Starting - MySuite: addition
Test Succeeded - MySuite: addition
Test Starting - MySuite: subtraction
Test Succeeded - MySuite: subtraction
But as of the latest ScalaTest 1.5 snapshot release will give you:
scala> (new MySuite).execute()
MySuite:
- addition
- subtraction
Another bit of user feedback was that people preferred to see the nested levels in the test class echoed in indentation levels in the output. ScalaTest has supported arbitrary levels of indentation since 1.0 in its event hierarchy, but didn't fire indentation of more than one level from any ScalaTest trait, not even from Spec, which allowed arbitrarily deep levels of nesting. My thought was that most often people wouldn't actually nest more deeply than two levels, and I felt that it was more readable to flatten two levels to one. Also I observated Ruby's RSpec tool, which inspired Spec's describe/it syntax, at the time flattened everything to one level. I wasn't sure which way to go, so I followed RSpec initially. Meanwhile Eric Torreborre indented specs output to match the input, and I observed that led some specs users to nest text more deeply, and even RSpec now indents its output this way. The ScalaTest users I asked about this for the most part indicated they would like the indented output. So now given this Spec:
describe
it
import org.scalatest.Spec
class MySpec extends Spec {
describe("A Stack") {
describe("(when empty)") {
it("should be empty") (pending)
it("should complain on peek") (pending)
it("should complain on pop") (pending)
}
describe("(when full)") {
it("should be full") (pending)
it("should complain on a push") (pending)
}
}
}
Instead of getting the output you get with ScalaTest 1.3:
scala> (new MySpec).execute()
A Stack (when empty)
- should be empty (pending)
- should complain on peek (pending)
- should complain on pop (pending)
A Stack (when full)
- should be full (pending)
- should complain on a push (pending)
As of the latest ScalaTest 1.5 snapshot, you will get:
scala> (new MySpec).execute()
MySpec:
A Stack
(when empty)
- should be empty (pending)
- should complain on peek (pending)
- should complain on pop (pending)
(when full)
- should be full (pending)
- should complain on a push (pending)
For two levels of indentation, it isn't necessarily an improvement in readability, but at more levels it is more clearly a readability win. For example, given this WordSpec:
import org.scalatest.WordSpec
class ScalaTestGUISpec extends WordSpec {
def theUser = afterWord("the user")
def display = afterWord("display")
def is = afterWord("is")
"The ScalaTest GUI" when theUser {
"clicks on an event report in the list box" should display {
"a blue background in the clicked-on row in the list box" in {}
"the details for the event in the details area" in {}
"a rerun button" that is {
"enabled if the clicked-on event is rerunnable" in {}
"disabled if the clicked-on event is not rerunnable" in {}
}
}
}
}
Instead of the ScalaTest 1.3 output of:
scala> (new ScalaTestGUISpec).execute()
The ScalaTest GUI (when the user clicks on an event report in the list box)
- should display a blue background in the clicked-on row in the list box
- should display the details for the event in the details area
- should display a rerun button that is enabled if the clicked-on event is rerunnable
- should display a rerun button that is disabled if the clicked-on event is not rerunnable
As of the latest ScalaTest 1.5 snapshot, you'll get:
scala> (new ScalaTestGUISpec).execute()
ScalaTestGUISpec:
The ScalaTest GUI
when the user clicks on an event report in the list box
should display
- a blue background in the clicked-on row in the list box
- the details for the event in the details area
a rerun button that is
- enabled if the clicked-on event is rerunnable
- disabled if the clicked-on event is not rerunnable
These enhancements will be released as part of ScalaTest 1.5 within the next few weeks. I'm posting this preview now because I want to get feedback in general on the API and find if there are any bugs to fix or any code-breakages. (I expect no source code to break with any of these enhancements, so let me know if you have a problem.)

Driving your Marketing Campaigns¶
Lead Automation with Marketing Campaigns¶
OpenERP offers a set of modules allowing you to easily create and track your Marketing Campaigns. With the Marketing application, you define your direct marketing campaigns, allowing you to automate your lead communication. You can install the module through the Reconfigure wizard, then select Marketing.
Campaigns can be displayed in List or Diagram view. The Diagram view allows you to clearly see the marketing actions (represented by a node) and the applied conditions (represented by an arrow).
A marketing campaign is an event or an activity that will help you manage and reach your partners with specific messages. A campaign can have many activities that will be triggered from a specific situation, for instance a response from a contact to an email you sent. The result of such a response (action) could be the sending of an email, for which a template has previously been created in OpenERP.
To use the email functionality, you have to configure your email account. This is explained in the chapter ch-crm-fetchmail-install.
Example of a Complete Marketing Campaign¶
Suppose we are an insurance company that wants to launch a marketing campaign to generate new leads. The company launches a campaign on its website and proposes potential customers to get a free offer for their car insurance.
Each time a customer registers himself through the contact form, a lead is created in OpenERP. For further information about web contact forms, please refer to the chapter Automating your Lead Acquisition.
The salesperson responsible for Car Insurances triggers the marketing campaign by sending an introductory email of all the insurance services we offer and thanking for subscribing for the free Car Insurance Offer.
Based on the response, the insurance company plots whether the lead is interested in:
Buying a Car Insurance,
Information about other Insurance policies,
Buying the book about Keeping your Children Safe.
According to the replies we receive from the leads, we send an email catering their respective needs.
If they respond back to such an email, the lead is converted into an opportunity. When the lead buys a car insurance, the lead becomes our partner and is created as a customer in OpenERP.
If we do not receive an answer, they get a reminder regarding the offer a week later. If they still do not answer, our salesperson gives a voluntary call to ask about their needs.
See it as a flowchart allowing us to trigger a respective activity for every possible cue. The chances of leads going unattended become very low, and for every lead, we have a predefined method of handling it.
Moreover, we can measure the method according to our goals. Based on the goals we can evaluate the effectiveness of our campaign and analyze whether there is room for improvement.
Совет
Campaign Example
To a get an example of a complete campaign in OpenERP, you can install the marketing_campaign_crm_demo module.
Designing your Campaigns¶
Designing a marketing campaign is mostly a long term process and the success of any campaign depends on the research and the effectiveness in selecting your target audience for the campaign. There are certain questions that every marketeer always asks while designing a campaign.
What would be our marketing campaign?
Who would be the target audience?
How would we measure the effectiveness of our campaign?
The OpenERP campaign is based on the principle of lead automation. A lead is created according to a specific response by a customer towards a stimulus. An example: filling the car insurance calculator on your website may create a lead in OpenERP.
The first step is to define the campaign, i.e. the sequence of steps to be performed. By defining the campaign, we trigger a set of activities in the Marketing Campaign application of OpenERP.
From the lead automation, we define the sequence of steps we ought to follow, the modes of creating and processing these activities and the cost involved in this campaign. After each activity and based on its respective stimuli, we can trigger the next event of the campaign concerned.
Segmenting your Campaigns¶
The two most important points for any successful campaign are the adoption of a concrete methodology of execution and choosing the right segment: a target loop of customers to whom our campaign would be directed (i.e. your target audience). Inappropriate focus on the wrong segment would result in the campaign being misfired and our efforts would reach deaf ears.
Through the Segment tab in the Campaign module, we can define our segment for each Campaign activity. Indeed, it is perfectly well possible that with every step downwards, the segment gets narrowed in terms of number. You can also synchronize the entire campaign steps according to the defined segments.
Our insurance company wants to attack the Spanish market, and will define a segment called Spanish Leads. Of course you would want your segment to be valid for leads coming from Spain only. To achieve this, go to the Leads list view. Filter all the leads for Spain (type Spain in the Country field), make sure to clear the salesteam, so that all leads coming from Spain will be selected. Then click Save Filter and call it for instance Spanish Leads. Now return to the Campaigns menu and open the Segment, then click the Filter field to select Spanish Leads. The segment will now only apply to Spanish leads.
As you can see, the Marketing Campaign module is closely synchronized with the Customer Relationship Management Business Application. Let us consider the segment we cater in the campaign as Leads in OpenERP. Goals are set for each campaign, which would be considered as a desired state. Once a lead meets our objective criteria of goals, we change the lead status by converting it into an Opportunity, meaning that we should give focused attention.
Once the lead satisfies our final objective, we would consider it as a partner/customer and close that lead.
OpenERP allows you to create your own email templates. You can use the Expression Builder to have the variables created for you. Suppose you would like to add the Contact Name in the email, but of course, this will be a different name for each email.
In the Expression Builder, in Field, select Contact Name. Automatically, the Expression will be filled. Copy the value from the expression and paste it in your email, e.g. Dear ${object.contact_name}. So your email will start with Dear followed by the name of the contact. This way you automatically create personalized emails.
For each email template, you can have OpenERP generate a Wizard Action / Button that will be related to the object. So if you choose to do marketing campaigns for leads, the action will be added to the right side panel of the Lead form.
Совет
Configuring Marketing Campaigns
Please notice that it requires some technical knowledge to configure Marketing Campaigns. To be able to see, create, edit campaign, users need to be in the Marketing / User group.
Setting up your Marketing Campaigns¶
Введение
A campaign defines a workflow of activities that items/objects entering the campaign will go through. Items are selected by segments. Segments are automatically processed every few hours and inject new items into the campaign, according to a given set of criteria. It is possible to watch the campaign as it is running, by following the campaign "workitems". A workitem represents a given object/item passing through a given campaign activity. See it as a step that still can go either way. Workitems are left behind when the item proceeds to the next activities. This allows an easy analysis and reporting on the running campaign. Each activity may execute an action upon activation depending on a dynamic condition. When the condition is not met, the workitem is cancelled/deleted; if the condition is met, the action is executed, the workitem is marked as Done, and propagated to the next activities.
Campaigns (Marketing ‣ Campaigns ‣ Campaigns)
- Campaign
Each campaign is made of activities and transitions, and must be defined on any specific object the system knows about (e.g. Leads, Opportunities, Employees, Partners).
- Mode
A campaign can be in one of 4 modes:
Test Directly: processes the whole campaign in one go, ignoring any delay put on transitions, and does not actually execute the actions, so the result is simply the set of corresponding campaign workitems (see below). Any time a segment adds new items in the campaign they will be processed in the same manner.
Test in Real time: processes the campaign but does not actually execute the actions, so the result is simply the set of corresponding campaign workitems. Any time a segment adds new items in the campaign they will be processed in the same manner.
Manual confirmation: No action will be executed automatically, a human intervention is needed to let workitems proceed into the flow. It is like a step-by-step manual process using the Campaign Followup menu. You can ignore the time delays and force any step of the campaign, implementing the campaign at your pace i.e. (you have a test email and want to see if the steps and templates do exactly what you want them to do). You will see that the actions set are defined as To Do and Done and the page has to be refreshed to see the next activities defined by the campaign node: the campaign sends real messages to the actual targets, be warned.
Normal: the campaign is processed normally, all actions are executed automatically at the scheduled date. Pay attention that in this status, the campaign sends real messages to the actual target audience.
Regardless of the current mode of the campaign, any workitem can be manually executed or cancelled at any time (even if it is scheduled in the future) through Campaign Followup.
- Resource
Specifies where the campaign will get the information from, i.e. the OpenERP object linked (e.g. Leads, Opportunities, Employees, Partners).
- Activities
Activities are steps in the campaign. Each activity is optionally linked to previous and next activities through transitions.
Each activity has:
-
one optional condition that stops the campaign,
-
one action to be executed when the activity is activated and the condition is True (could be a 'do nothing' action),
-
one optional signal (ignore it),
-
a start flag.
Start Activity
Activities that have the Start checkbox set, will receive a new workitem corresponding to each new resource/object entering the campaign. It is possible to have more than one Start Activity, but not less than one.
Activity Conditions
[a Boolean expression, made of clauses combined using boolean operators: AND, OR, NOT] Each condition is the criterion that decides whether the activity is going to be activated for a given workitem, or just cancelled. It is an arbitrary expression composed of simple tests on attributes of the object, possibly combined using or, and & not operators.
See section 6.1 for more information on Comparators.
The individual tests can use the "object" name to refer to the object/resource it originates from (e.g the lead), using a "dot notation" to refer to its attributes. Some examples on a CRM Lead resource:
-
object.name == 'Insurance Offer Lead' would select only leads whose title is exactly "Insurance Offer Lead",
-
object.state == 'pending' would select Pending leads only,
-
object.country_id.code == 'be' would select leads whose country field is set to Belgium,
-
object.country_id.name == 'Belgium' would select leads whose country field is set to Belgium.
Tests can also use a 'workitem' name to refer to the actual item denoting the position of the object in the campaign. This can be useful to access some specific attributes, such as the segment that selected this item. Some examples:
-
workitem.segment_id.name == 'Insurance Offer EU Zone1 - Industry Consulting/Technology' would select leads that entered this campaign through the "Insurance Offer Lead EU Zone1 - Industry Consulting/Technology" segment,
-
'EU Zone1' in workitem.segment_id.name would select only leads that entered the campaign through a segment that has "EU Zone1" in its name.
Совет
In the GTK client you can use "Help > Enable Debug mode tooltips" to see the attribute name of every field in a form. These are the same that you can use during import/export with CSV files.
You can also use the special formula re.search(PATTERN_TO_SEARCH, ATTRIBUTE_TO_SEARCH) where PATTERN_TO_SEARCH is a character string delimited with quotes, and ATTRIBUTE_TO_SEARCH uses the dot notation above to refer to a field of the object. An example for CRM leads:
-
re.search('Plan to buy: True', object.description) would be true if the Notes on a Lead contain this text: "Plan to buy: True". Be careful that all spaces etc. do matter, so you may use the special pattern characters as detailed at the bottom to account for small variations,
-
re.search('Plan to.*True', object.description) would be true if the Notes on a Lead contain this text: "Plan to" followed later on by "True".
You can combine individual tests using boolean operators and parentheses. Some examples on a CRM Lead resource:
-
object.state != 'pending' and ( re.search('Plan to by:.*True',object.description) and not re.search('Plan to use:.*True',object.description) ) would be true if the lead is NOT in Pending state and it contains "Plan to buy", but not "Plan to use".
Guidelines for Creating a Campaign¶
-
It is a good idea to have an initial activity that will change some fields on the objects entering the campaign to mark them as such, to avoid mixing them in other processes (e.g. set a specific state and Sales Team on a CRM lead being processed by a campaign). You can also define a time delay so that the campaign seems more human (note if the answer comes in a matter of seconds or minutes it is computer generated).
-
Put a stop condition on each subsequent activity in the campaign to get items out of the campaign as soon as the goal is achieved (e.g. every activity has a partial condition on the state of the item, if CRM Leads stops being Pending, the campaign ends for that case).
-
The Email headers: to, from, cc, bcc, subject
-
The raw HTML body, with the low-level markup and formatting
-
The plaintext body
Headers and bodies can contain placeholders for dynamic contents that will be replaced in the final email with the actual content.
Campaign Segments
Segments are processed automatically according to a predefined schedule set in the menu Administration ‣ Configuration ‣ Scheduled Actions. It could be set to process every 4 hours or every minute for example. This is the only entry point in a campaign at the moment.
Segment filters
Segments select resources via filters, exactly the same kind of filter that can be used in advanced search views on any list in OpenERP. You can actually create them easily from any OpenERP screen allowing you to save filters. Save your advanced search criteria as a new filters and add them to the segment in the Filter field. Filters mainly consist in a domain expressing the criteria of selection on a model (the resource). See section 10.3 for more information on the syntax for these filters.
- For Leads, the following filter would select draft Leads from any European country with "Plan for use: True" or "Plan for buy: False" specified in the body:
- [ ('type','=','lead'),
('state', '=', 'draft'), ('country_id.name', 'in', ['Belgium', 'Netherlands', 'Luxembourg', 'United Kingdom', 'France', 'Germany', 'Finland', 'Denmark', 'Norway', 'Austria', 'Switzerland', 'Italy', 'Spain', 'Portugal', 'Ireland', ]), '|', ('description', 'ilike', 'Plan for use: True'), ('description', 'ilike', 'Plan for buy: False') ]
Miscellaneous References, Examples
6.1 Reference of Comparison Operators:
-
==: Equal
-
!=: Not Equal
-
<: Bigger than
-
>: Smaller Than
-
<=: Bigger than or equal to
-
>=: Smaller than or equal to
-
in: to check that a given text is included somewhere in another text. e.g "a" in "dabc" is True
6.2 Reference of Pattern/Wildcard characters
-
. (dot) represents any character (but just one)
-
* means that the previous pattern can be repeated 0 or more times
-
+ means that the previous pattern can be repeated 1 or more times
-
? means that the previous pattern is optional (0 or 1 times)
-
.* would represent any character, repeated 0 or more times
-
.+ would represent at least 1 character (but any)
-
5? would represent an optional 5 character
6.3 Reference of filter domains
Generic format is: [ (criterion_1), (criterion_2) ] to filter for resources matching both criterions. It is possible to combine criterions differently with the following operators:
-
'&' is the boolean AND operator and will make a new criterion by combining the next 2 criterions (always 2). This is also the implicit operator when no operator is specified.
-
for example: [ (criterion_1), '&', (criterion_2), (criterion_3) ] means criterion_1 AND (criterion_2 AND criterion_3)
-
'|' is the boolean OR operator and will make a new criterion by combining the next 2 criterions (always 2)
-
for example: [ (criterion_1), '|', (criterion_2), (criterion_3) ] means criterion_1 AND (criterion_2 OR criterion_3)
-
'!' is the boolean NOT operator and will make a new criterion by reversing the value of the next criterion (always only 1)
-
for example: [ (criterion_1), '!', (criterion_2), (criterion_3) ] means criterion_1 AND (NOT criterion_2) AND criterion_3
Criterion format is: ( 'field_path_operand', 'operator', value )
Where:
-
field_path_operand specifies the name of an attribute or a path starting with an attribute to reach the value we want to compare
-
operator is one of the possible operator:
-
'=' , '!=' : equal and different
-
'<', '>', '>=', '<=' : greater or lower than or equal
-
'in', 'not in' : present or absent in a list of value. Values must be specified as [ value1, value2 ], e.g. [ 'Belgium', 'Croatia' ]
-
'ilike' : search for string value in the operand
-
value is the text or number or list value to compare with field_path_operand using comparator
Pushing your Campaign Results further¶
Of course, Marketing Campaigns can only be effective when you also do something with the results. OpenERP offers analysis features to help you better manage future campaigns based on the outcome of past campaigns. Learning from your results, that is.
The Marketing ‣ Reporting ‣ Campaign Analysis report allows you to analyse your campaigns in detail, both ongoing and completed campaigns.
Segments allow you to keep good track of the results of a marketing campaign. You can see from which segment you have most demands, for instance.
Thanks to good insights in the way your respondents answer to your campaign, you can continuously improve your marketing results!
Automating your Lead Acquisition¶
Through your website, your company wants to get as much information as possible about the people who visit the website. But how can you make sure that every person who wants to know more about your company is actually registered somewhere?
Well, you could use a Contact form for this. And precisely such a form allows you to register contacts automatically in OpenERP. By creating a link from your website's Contact form to OpenERP, your contact data will automatically be created in the CRM (or any other application of your choice, such as HR).
Let us show you an example of how this can be achieved. The figure below shows a Contact form on a website.
All data entered in this form are linked to the Lead form in the CRM. Each time someone enters this contact form, a new lead is automatically created in OpenERP.
Such a system is a very easy yet flexible way of keeping track of your leads and automatically launch your marketing campaigns.
How to Link a Web Contact Form to OpenERP?¶
OpenERP is accessible through XML-RPC interfaces, for which libraries exist in many languages.
Python example
import xmlrpclib # ... define HOST, PORT, DB, USER, PASS url = '' % (HOST,PORT) sock = xmlrpclib.ServerProxy(url) uid = sock.login(DB,USER,PASS) print "Logged in as %s (uid:%d)" % (USER,uid) # Create a new lead url = '' % (HOST,PORT) sock = xmlrpclib.ServerProxy(url) args = { 'name' : 'A New Lead', 'description' : 'This is a new lead from the web contact form', 'inventor_id': uid, } lead_id = sock.execute(DB,uid,PASS,'crm.lead','create',args)
PHP Example
<? include('xmlrpc.inc'); // Use phpxmlrpc library, available on sourceforge // ... define $HOST, $PORT, $DB, $USER, $PASS $client = new xmlrpc_client(""); $msg = new xmlrpcmsg("login"); $msg->addParam(new xmlrpcval($DB, "string")); $msg->addParam(new xmlrpcval($USER, "string")); $msg->addParam(new xmlrpcval($PASS, "string")); resp = $client->send($msg); uid = $resp->value()->scalarval() echo "Logged in as $USER (uid:$uid)"
// Create a new lead $arrayVal = array( 'name'=>new xmlrpcval("A New Lead", "string") , 'description'=>new xmlrpcval("This is a new lead from the web contact form" , "string"), 'inventor_id'=>new xmlrpcval($uid, "int"), );
$msg = new xmlrpcmsg('execute'); $msg->addParam(new xmlrpcval($DB, "string")); $msg->addParam(new xmlrpcval($uid, "int")); $msg->addParam(new xmlrpcval($PASS, "string")); $msg->addParam(new xmlrpcval("crm.lead", "string")); $msg->addParam(new xmlrpcval("create", "string")); $msg->addParam(new xmlrpcval($arrayVal, "struct")); $resp = $client->send($msg); ?>

Profiling your Customers¶
The segmentation tools let you create partner groups (or categories) and act on each segment differently according to questionnaires. For example, you could create pricelists for each of the segments, or start phone marketing campaigns by segment. To allow you to work with segments in OpenERP, you should install the crm_profiling module, which can also be achieved from the Configuration Wizard (Marketing - Profiling).
Profiling can be used to qualify your customers according to a questionnaire you define. When you establish a good customer profile, this will surely help you to close your deals. Customer profiles might even help you beat your competitors!
Establishing the Profiles of Prospects¶
During presales activities it is useful to qualify your prospects quickly. You can ask a series of questions to find out what product / service to offer to the customer, or how quickly you should handle the request.
Совет
Профилирование
This method of rapidly qualifying prospects is often used by companies who carry out presales by phone. A prospect list is imported into the OpenERP system as a set of partners and the operators then ask a series of questions to each prospect by phone.
Ответы на эти вопросы позволяют быстро классифицировать каждого потенциального клиента, что ведет к предложению конкретных услуг и продуктов на основе этих ответов.
As an illustration, take the case of a software company which offers a service based on the OpenERP software. The company goes to several exhibitions and encounters dozens of prospects over a few days. It is important to handle each request quickly and efficiently.
The products offered at these exhibitions are:
training on OpenERP – for independent people or small companies,
partner contract – for IT companies that intend to offer an OpenERP service,
OpenERP as SaaS – for small companies,
совместная встреча с партнером для проведения демонстрации, нацеленной на проведение интеграции программного обеспечения -- для компаний большего размера.
The IT company has therefore put a decision tree in place based on the answers to several questions to prospects. These are given in the following figure Example of Profiling Customer Prospects by the OpenERP Company:
The sales person starts by asking the questions mentioned above and then after only a couple of minutes of work, he can decide what to propose to the prospective customer simply by analysing the prospect's answers.
At the end of the exhibition, prospects' details and their responses to the questionnaire are entered into OpenERP. The profiling system automatically classifies the prospects into appropriate partner categories.
This enables your sales people to efficiently follow up prospects and adapt their approach according to each prospect's profile. For example, they can send a letter based on a template developed for a specific partner category. They would use OpenERP's report editor and generator for their sales proposition, such as an invitation to a training session a week after the show.
Using Profiles effectively¶
To use the profiling system, you have to install OpenERP's crm_profiling module. You can also use the Reconfigure Wizard and add Marketing / Profiling.
Once the module is installed, you can create several questionnaires through the menu Sales ‣ Configuration ‣ Leads & Opportunities ‣ Questionnaires. For each questionnaire, OpenERP allows you to create a list of questions and the possible responses through the menu Sales ‣ Configuration ‣ Leads & Opportunities ‣ Questions.
Для получения представленной ранее схемы вы можете создать следующие вопросы и ответы:
Например, сотрудник отдела продаж, специализирующийся на больших клиентах для сектора услуг, может иметь профиль, определенный примерно так:
Budget for integration: Unknown , 100k-300k or >300k ,
Already created a specification for the work? Yes , No
Industry Sector? Services .
When entering the details of a specific prospect, the prospect's answers to various questions can be entered in the Profiling tab of the Partner form. All you have to do is click the Use a Questionnaire button on the Profiling tab of the Partner form.
OpenERP will automatically assign prospects to the appropriate partner category based on these answers.
Customers corresponding to a specific search profile can be treated as a priority. The sales person can access the profile of the large active accounts easily. | https://doc.odoo.com/6.1/ru/book/2/9_Marketing/ | CC-MAIN-2019-09 | refinedweb | 4,201 | 53.81 |
Introduction the phases of an application lifecycle we are going to focus on today is the testing phase. Tests can take place on the developer’s machine and by leveraging these test in an automated way on DevCS, we ensure the quality of the code throughout the lifecycle of the code.
Main Article
In this article we will take a closer look at using Node.JS in combination with Jasmine to test our code and configure an automated test script that will run every time a developer pushes his code to a specific branch in the code repository.
Why testing?
To many developers it is clear that testing can be advantages however many feel that testing adds an overhead to their already busy schedule. This is mainly a misconception as proper testing will increase the quality of the code. If you don’t test, you will spend more time debugging your code later on so you could say that testing is a way of being lazy by spending some more time in the beginning.
In addition to this, testing is not just a tool to make sure your code works, it can also be used as a design tool. This comes from the Behavior-driven development paradigm. The idea is to define your unit test before writing any code. By doing this, you will have a clear understanding of the requirements of the code and as such, your code will be aligned with the requirements.
This also increases the re-usability of the code because a nice side effect of designing your code this way is that your code will be very modular and loosely coupled.
When we talk about Node.JS and JavaScript in general, the side effect of a “test-first” approach is that it will be much easier to reuse your code no matter if it’s client side JavaScript or server side JavaScript. This will become clear in the example we will build in this article.
Different types of test
When we take about writing tests, it is important to understand that there are different types of tests, each testing a specific area of your application and serving their own purpose:
Unit Tests
Unit tests are your first level of defense. These are the tests run on your core business logic. A good unit test does not need to know the context it is running on and has no outside dependencies.
The purpose of a unit test is like the name says: to test a unit of work. A typical example of a unit test is to test a function that checks if a credit card number is valid. That method doesn’t need to understand where the credit card number is coming from, nor does it need to understand anything around security or encryption. All it does is take a credit card number as input and returns a true or false value depending on the validity of the number.
Integration Tests
The next level of tests are the integration tests. These will test if all your different modules integrate well and test if the data coming from external sources is accurate.
It will group the different modules and check if these work well together. It will check for data integrity when you pass information from one module to another and makes sure that the values passed through are accurate.
End 2 End Tests
An end 2 end test typically requires a tool that allows you to record a user session after which that session is replayed. In a web application, Selenium is popular tool to perform these E2E tests. In such a scenario, you will define certain areas on the page that you know should have specific value. When the HTML of these areas are different from what you define, the test will fail. This is the highest level of testing you can have.
In this post we will focus on unit testing.
Creating a new project on Developer Cloud Service
Before we can start writing code, we need to define a project in Developer Cloud Service (DevCS). A project in DevCS is much more than a code repository. It also allows us to manage the development lifecycle by creating tasks and assigning them to people. It also provides a scrum board so we can manage project in an agile way.
In this post, we will create a microservice that does temperature conversion. It will be able to convert Celsius and Fahrenheit temperatures to each other and Kelvin.
In DevCS we define a new project called “Converter”:
As template we select the “Initial Repository” as this will create the code repository we will be using to check in our code.
In the next step, we define the properties and we initialize a repository with readme file:
Now we can continue and create our project.
Once the project is created, you will see your project dashboard:
As you can see, the system created a repository called converter.git. On the right hand side you can find the HTTP and SSH links to the repo. We will need the HTTP link in order to clone the initial repository before we can start coding.
Once you copied the HTTP link to your GIT repo, you can open a command line so we can clone the repo.
At the location you want the repo to be created, we simply execute following command:
D:\projects\Oracle\testing>git clone https://<yourRepo> Cloning into 'converter'... Password for '': remote: Counting objects: 3, done remote: Finding sources: 100% (3/3) remote: Getting sizes: 100% (2/2) remote: Compressing objects: 100% (37/37) remote: Total 3 (delta 0), reused 0 (delta 0) Unpacking objects: 100% (3/3), done. Checking connectivity... done.
This will clone the repository into a folder called “converter”. At the moment that folder will only contain a README.md file. The next step is to initialize that folder as a node.js project. This can easily be done by using the npm init command:
D:\projects\Oracle\testing>cd converter D:\projects\Oracle\testing\converter: (converter) version: (1.0.0) description: entry point: (index.js) app.js test command: git repository: (https://<yourURL>) keywords: author: license: (ISC) About to write to D:\projects\Oracle\testing\converter\package.json: { "name": "converter", "version": "1.0.0", "description": "converter.git", "main": "app.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "repository": { "type": "git", "url": "<yourURL>" }, "author": "", "license": "ISC" } Is this ok? (yes)
This will have created the package.json file.
The next thing we need to do is installing the required modules.
For this example we will use express and the body-parser module to give us the basic middleware to start building the application. For testing purpose we will use jasmine which is a popular framework for behavior driven testing. Jasmine will be configured as a development dependency.
We will add following content to the package.json:
"dependencies": { "body-parser": "^1.15.2", "express": "^4.14.0" }, "devDependencies": { "jasmine": "^2.5.2" }
Now we can simply install these modules by executing the npm install command from within the application’s folder.
Writing tests
Now that the project has been setup and we downloaded the required dependencies, we can start writing our code, or should I say, writing our tests?
Like I said in the introduction, we can use testing as a tool to design our service signature and this is exactly what we are going to do.
Jasmine is a perfect framework for this as it is designed to define behaviors. These behaviors will be translated to units of code that we can easily test.
If we think about our temperature converter that we are going to write, what behaviors would we have?
- Convert Celsius to Fahrenheit
- Convert Celsius to Kelvin
- Convert Fahrenheit to Celsius
- Convert Fahrenheit to Kelvin
Each of these behaviors will have its own piece of implementation that can be mapped to some testing code.
Before we can write our tests, we need to initialize the project for Jasmine. This can be done by executing the jasmine init command from within your application root:
node node_modules/jasmine/bin/jasmine.js init
This command will create a spec folder in which we need to write the specifications of our tests.
In that folder we create a new file converterSpec.js
It is important to end the filename with Spec because Jasmine has been configured to search for files that end with Spec. You can of course, change this behavior by changing the spec_files regex in the jasmine.json file in the support folder but by default Jasmine will look for every file ending in Spec in the spec folder.
The contents of the converterSpec.js will look like this:
describe("Converter ",function(){ it("converts celsius to fahrenheit", function() { expect(converter.celsiusToFahrenheit(0)).toBeCloseTo(32); expect(converter.celsiusToFahrenheit(-10)).toBeCloseTo(14); expect(converter.celsiusToFahrenheit(23)).toBeCloseTo(73.4); expect(converter.celsiusToFahrenheit(100)).toBeCloseTo(212); }); it("converts fahrenheit to celsius", function() { expect(converter.fahrenheitToCelsius(32)).toBeCloseTo(0); expect(converter.fahrenheitToCelsius(14)).toBeCloseTo(-10); expect(converter.fahrenheitToCelsius(73.4)).toBeCloseTo(23); expect(converter.fahrenheitToCelsius(212)).toBeCloseTo(100); }); it("converts celsius to kelvin", function() { expect(converter.celsiusToKelvin(0)).toBeCloseTo(273.15); expect(converter.celsiusToKelvin(-20)).toBeCloseTo(253.15); expect(converter.celsiusToKelvin(23)).toBeCloseTo(296.15); expect(converter.celsiusToKelvin(100)).toBeCloseTo(373.15); }); it("converts fahrenheit to kelvin", function() { expect(converter.fahrenheitToKelvin(32)).toBeCloseTo(273.15); expect(converter.fahrenheitToKelvin(14)).toBeCloseTo(263.15); expect(converter.fahrenheitToKelvin(73.4)).toBeCloseTo(296.15); expect(converter.fahrenheitToKelvin(212)).toBeCloseTo(373.15); }); });
These tests will fail because we haven’t written a converter yet.
We can execute this test suite by calling Jasmine from our root directory of the application:
node node_modules/jasmine/bin/jasmine.js
The output will contain some erros and a message saying that 4 out of 4 specs have failed:
D:\projects\Oracle\testing\converter>node node_modules/jasmine/bin/jasmine.js Started FFFF Failures: 1) Converter converts celsius to fahrenheit Message: ReferenceError: converter is not defined Stack: ReferenceError: converter is not defined at Object.<anonymous> (D:\projects\Oracle\testing\converter\spec\converterSpec.js:9:16) 2) Converter converts fahrenheit to celsius Message: ReferenceError: converter is not defined Stack: ReferenceError: converter is not defined at Object.<anonymous> (D:\projects\Oracle\testing\converter\spec\converterSpec.js:16:16) 3) Converter converts celsius to kelvin Message: ReferenceError: converter is not defined Stack: ReferenceError: converter is not defined at Object.<anonymous> (D:\projects\Oracle\testing\converter\spec\converterSpec.js:23:16) 4) Converter converts fahrenheit to kelvin Message: ReferenceError: converter is not defined Stack: ReferenceError: converter is not defined at Object.<anonymous> (D:\projects\Oracle\testing\converter\spec\converterSpec.js:30:16) 4 specs, 4 failures Finished in 0.01 seconds
By writing these tests, we established that our convertor should have following methods:
- celsiusToFahrenheit
- fahrenheitToCelsius
- celsiusToKelvin
- fahrenheitToKelvin
Implementing the converter
Once the signature of our code has been established, we can start implementing the code.
In our case, we need to create an object for the converter with the required functions. Therefore we create a new file converter.js with the following content:
var Converter = function(){ var self = this; } Converter.prototype.celsiusToFahrenheit = function(temp){ return temp*9/5+32; }; Converter.prototype.fahrenheitToCelsius = function(temp){ return (temp-32)/1.8; }; Converter.prototype.celsiusToKelvin = function(temp){ return temp +273.15; } Converter.prototype.fahrenheitToKelvin = function(temp){ var cel = this.fahrenheitToCelsius(temp); return this.celsiusToKelvin(cel); } if (typeof exports == 'object' && exports) exports.Converter = Converter;
Now that the implementation is done, we can include this file in our converterSpec.js so the test will use this object:
At the top of converterSpec.js add the following lines:
var Converter = require("../converter").Converter; var converter = new Converter();
If we rerun the jasmine tests we will notice that they succeed:
D:\projects\Oracle\testing\converter>node node_modules/jasmine/bin/jasmine.js Started .... 4 specs, 0 failures Finished in 0.005 seconds
So far, wrote some tests and implemented a plain old JavaScript object. We haven’t written any server specific code but yet, our core business logic is already done and tested.
Notice how we wrote this code without worrying about things like request body, response objects, get, post and other server specific logic. This is a very powerful feature of writing test in this way because now the exact same code can be used in any project that used JavaScript. No matter if it’s Node.JS, Oracle JET, Angular, Ionic,… it should work in any of these frameworks and we didn’t even spend additional time optimizing the code for this. It’s just a bi-product of a test-first approach!
Implementing the server
The last step is to write our server that consumes the converter. Our server will expose a single endpoint where we can specify an object with a temperature value and a units value. Based upon the units value, the converter will make al the required conversions and send the result back to the user.
Create a new file app.js with following contents
var express = require("express"); var parser = require("body-parser"); var app = express(); var http = require('http').Server(app); app.use(parser.json()); var Converter = require("./convertor").Converter; var converter = new Converter(); app.post("/convert",function(req,res){ var temp = req.body.temp; var units = req.body.units; var result = {}; if(units.toLowerCase() == "f"){ result.fahrenheit = temp; result.celsius = converter.fahrenheitToCelsius(temp); result.kelvin = converter.fahrenheitToKelvin(temp); } else if(units.toLowerCase() == "c"){ result.celsius = temp; result.fahrenheit = converter.celsiusToFahrenheit(temp); result.kelvin = converter.celsiusToKelvin(temp); } res.send(result); res.end(); }); http.listen(3000, function(){ console.log('listening on *:3000'); });
Setting up automated testing on Developer Cloud Service
Once we have a first finished version of the code, it’s a good time to commit our code to the code repository. At the same time, we want to setup a build process on DevCS so that every time we commit code to the repository. it will fire of the tests we created so far.
In order to do this, we first need to modify the package.json so that we can make use of the npm test command to start the test.
This is fairly simple as npm test is just a shortcut to a script you define in the package.json. This should be the same command as we use when starting the tests from our command line.
Modify package.json so the scripts part looks like this:
"scripts": { "test": "node node_modules/jasmine/bin/jasmine.js" },
When you save the file and execute npm test from a command line in the root folder of your application, it should start the tests.
Adding a .gitignore file
The next step we have to do before committing the code, is to add a gitignore file. This file will tell GIT what files and folder to ignore. The reason why we want this is because it’s a bad practice to include the node_modules folder in your code repository. The code in that folder isn’t written by us and we can simply initialize a new consumer of the repo by executing npm install. This way the modules don’t take additional space in the repository and it will be much faster to upload the code.
The .gitignore file needs to be put in the root of your application. For this application we only need to ignore the node_modules folder so the file will look like this:
# Dependency directories node_modules
Creating a build configuration in DevCS
Before we commit the code, we need to setup a build configuration in DevCS.
A build configuration is a sequence of actions that can be configured depending on the type of application. For example when you are developing a J2EE application, the build configuration can execute a maven build, build the JAR/EAR file and pass it on to a deployment script so it can be deployed automatically to Java Cloud Services.
In our case, we are working with Node.JS so technically we don’t have anything to build. However, a build config can still be usefull because it allows us to execute certain command to test the integrity of the code. If everything passes, we are able to hand it over to a deployment profile for Application Container Cloud Service to deploy it on the cloud.
In this step, we will focus on the build step.
In DevCS, select your project and go to the Build page. At the moment only a sample maven_build has been created which doesn’t do us any good so we will go ahead and create a new job.
Once we saved the job we will be redirected to the configuration.
The Main and Build Parameters tab can remain unchanged. In the Source Control tab we specify that the build system integrates with a GIT repository.
From the Repository drop down, we select our converter repo.
In the Branch section we click the Add button and select master. This way we can specify on which branch of the code this build applies.
It is a common practice to use something like GitFlow to develop features. Each feature will be represented by a branch and once the feature is finished, that branch is merged into a development branch. In these cases, it makes a lot of sense to only initiate the build when a commit is done towards the development branch so that’s why we specify a certain branch in this step. If we don’t specify a branch, the build will start on every single commit.
In the next tab, Triggers, we specify what triggers the build. Because we re relying on a commit to the source control system, we have to select “Based on SCM polling schedule”. This links the configuration from the Source Control tab to the Trigger.
The next tab Environment isn’t required in this step so we can go ahead and open the Build Steps tab. This is where we configure the actions that are done when the build starts.
In our case we want to execute the npm test command which is a shell script. From the add button we select the Execute Shell step. This will add a text area in which we can specify shell commands to execute. In this box we can add multiple lines of code.
Add the following code in the command box:
git config --global url. git://github.com/ npm install npm test
Because we have added the node_modules to our gitignore file, we need to install the modules from our package.json. On your machine a simple npm install would be sufficient, however because DevCS is behind a firewall that only accepts traffic on port 80 (HTTP) and 443 (HTTPS), we need to make sure that we force git to use HTTP and not the git protocol. The git config command does make sure that we download all the modules over regular HTTPS traffic, even if the git repository of a module has been configured using the git protocol.
After that we can install the modules using the npm install command and once this is done, a npm test will start the Jasmine tests.
Our build config is now complete.
Committing the code
Now that our build config has been setup, we can commit and push our code after which the build should start.
Commit the code using your favorite GIT client or from within your IDE. After the commit, push the changes to the master branch.
Once you have pushed the code, go back to the Jobs Overview page on DevCS and you will notice that our new build config has been queued and after a few seconds or a minute it will start:
After aboud half a minute, the build should complete and you should see the status:
On the right hand side you have a button that can take you to the Console Output. This gives you a good overview of what the build actually did. In our case, everything went fine and it ended in success however when your test fails, the build will fail and the console output will be crucial to identify what test failed.
This is the output from my build (I omitted the npm install output).

Conclusion
In this post we have shown how we can leverage the power of Developer Cloud Service to setup an automated test build for your Node.JS code. By doing this, you not only get the benefits of getting instant feedback when your code is pushed to the repository but you also get better quality and re-usability of your code.

If it is present it means transaction logging is * either enabled or in the process of being disabled in which case we can * ignore it as it will go away as soon as Windows gets its hands on it. * * To determine whether the transaction logging is enabled or in the process * of being disabled, need to check the volume flags in the * $VOLUME_INFORMATION attribute in the $Volume system file (which is present * in the root directory and has a fixed mft record number, see layout.h). * If the flag VOLUME_DELETE_USN_UNDERWAY is set it means the transaction log * is in the process of being disabled and if this flag is clear it means the * transaction log is enabled. * * The transaction log consists of two parts; the $DATA/$Max attribute as well * as the $DATA/$J attribute. $Max is a header describing the transaction * log whilst $J is the transaction log data itself as a sequence of variable * sized USN_RECORDs (see below for all the structures). * * We do not care about transaction logging at this point in time but we still * need to let windows know that the transaction log is out of date.

In our face-paced modern society, who has time to click through pages and pages of content? “Not I,” said the web developer. In a world full of shortcuts, swipes and other gestures, the most efficient way to get through pages of content is the infinite scroll.
While not a new concept, the idea of infinite scroll is still somewhat controversial. Like most things, it has a time and a place in modern web design when properly implemented.
For anybody unfamiliar, infinite scroll is the concept of new content being loaded as you scroll down a page. When you get to the bottom of the content, the site automatically loads new content and appends it to the bottom.
Infinite scroll may not be ideal for all types of content, it is especially useful of feeds of data that an end-user would most probably want to page through quickly.
A perfect use case, and one you may already be familiar with is Instagram. You are presented with a feed of images and as you scroll down, more images keep showing up. Over and over and over until they run out of content to give you.
This article will teach you how to implement the infinite scroll concept into a React component and uses the Random User Generator to load a list of users from.
🐊 Alligator.io recommends ⤵Fullstack Advanced React & GraphQL by Wes Bos
Before we begin, we need to make sure we have the proper dependencies in our project. To load data from the Random User Generator we are going to use superagent.
To add
superagent to your project via
npm run:
$ npm install --save superagent
Or via
yarn:
$ yarn add superagent
The crux of our infinite scroll component is going to be an
onscroll event that will check to see if the user has scrolled to the bottom of the page. Upon reaching the bottom of the page, our event will attempt to load additional content:
window.onscroll = () => { if ( window.innerHeight + document.documentElement.scrollTop === document.documentElement.offsetHeight ) { // Do awesome stuff like loading more content! } };
The data that has been loaded will be appended to an array in the component’s state and will be iterated through in the component’s
render method.
All good things come to an end. For demonstration purposes our component will eventually stop loading new content and display a message that it's reached the end and there is no additional content.
Now that we understand the logic flow that’s necessary to implement infinite scroll, let’s dive into our component:
import React, { Component, Fragment } from "react"; import { render } from "react-dom"; import request from "superagent"; class InfiniteUsers extends Component { constructor(props) { super(props); // Sets up our initial state this.state = { error: false, hasMore: true, isLoading: false, users: [], }; // Binds our scroll event handler window.onscroll = () => { const { loadUsers, state: { error, isLoading, hasMore, }, } = this; // Bails early if: // * there's an error // * it's already loading // * there's nothing left to load if (error || isLoading || !hasMore) return; // Checks that the page has scrolled to the bottom if ( window.innerHeight + document.documentElement.scrollTop === document.documentElement.offsetHeight ) { loadUsers(); } }; } componentWillMount() { // Loads some users on initial load this.loadUsers(); } loadUsers = () => { this.setState({ isLoading: true }, () => { request .get('') .then((results) => { // Creates a massaged array of user data const nextUsers = results.body.results.map(user => ({ email: user.email, name: Object.values(user.name).join(' '), photo: user.picture.medium, username: user.login.username, uuid: user.login.uuid, })); // Merges the next users into our existing users this.setState({ // Note: Depending on the API you're using, this value may // be returned as part of the payload to indicate that there // is no additional data to be loaded hasMore: (this.state.users.length < 100), isLoading: false, users: [ ...this.state.users, ...nextUsers, ], }); }) .catch((err) => { this.setState({ error: err.message, isLoading: false, }); }) }); } render() { const { error, hasMore, isLoading, users, } = this.state; return ( <div> <h1>Infinite Users!</h1> <p>Scroll down to load more!!</p> {users.map(user => ( <Fragment key={user.username}> <hr /> <div style={{ display: 'flex' }}> <img alt={user.username} src={user.photo} style={{ borderRadius: '50%', height: 72, marginRight: 20, width: 72, }} /> <div> <h2 style={{ marginTop: 0 }}> @{user.username} </h2> <p>Name: {user.name}</p> <p>Email: {user.email}</p> </div> </div> </Fragment> ))} <hr /> {error && <div style={{ color: '#900' }}> {error} </div> } {isLoading && <div>Loading...</div> } {!hasMore && <div>You did it! You reached the end!</div> } </div> ); } } const container = document.createElement("div"); document.body.appendChild(container); render(<InfiniteUsers />, container);
There’s really not much to it!
The component manages a few status flags and list of data in it’s state, the
onscroll event does most of the heavy lifting and the render method brings it to life on your screen!
We’re also making use of setState with a callback function passed-in as the second argument. The initial call to
setState in our
loadUsers method sets the value of loading to true and then in the callback function we load some users and call
setState again to append our new users to the users already in the state.
I hope you’ve found this article on implementing infinite scroll in React informative.
If interested, you can find a working demo of this component over on CodeSandbox.

Receive data on lopy through serial
I am trying to send string data from python over serial to my lopy. Could anyone tell me in steps how can i receive it and test if it is received on my lopy?
Thanks in advance!
@monersss At the moment, with my example, that happens when you get a timeout. But again, that would require some "out-of-band" signaling, meaning: in addition to the "payload", the jpg file, some control information must be exchanged. And that is part of a protocol. That could be pretty simple. If I grab one out of the air, it could be:
Define record types, where the first letter defines the type of the record, followed by 3 bytes record length, followed by the payload, like:
'fnnn': filename (of length nnn)
'd128': data
'x000': done
You would first receive 4 bytes, decode type and length, and then receive further 'length' bytes. And for every record received, your LoPy would send a confirmation, like the three bytes: "ok!" or "bad", in case of errors (or just a single byte).
That would implement flow control and the EOF signal. It does not have other elements like check sums and sequence control. But you might not need that.
@monersss by protocol implementing we mean simple thing
- you send command to destination "START_JPG"
- you send back e.g. "OK" or "UNKNOW"
- you send e.g 200Bytes of jpg + CRC(or MD5 or what you need to verify}
- you read that data and calculate CRC and compare and you send back "OK" or "retry" or "cancel"
....
all in your hand (look in google for e.g. handshake protocol)
@livius tried with lower speed, result is the same. I have never written a protocol So i am not really sure how to do it..
Another thing is That i would like my lopy to stop reading data when the whole for example 20 kB file was received, how can i do that??
@monersss
You also can decrease speed of transmision e.g 9600
but the best is what we suggest you at start
you must of course have some protocol implementing.
especially you can send info with e.g. md5 hash of portion of data back and if this is ok send more if not then repeat...
@monersss Flash is way slower than the SD, so jou are simply loosing data, because there is no flow control. For SD that works, because the firmware buffers some bytes, and that grants a time window for storing. AFAIK, the receive buffer is 256 bytes. Besides that, you code is highly ineffcient, because you open and close the file for every chunk of data. You could try it this way around:
from machine import UART import pycom import time from machine import SD import os #sd = SD() #os.mount(sd,'/sd') #os.listdir('/sd') uart = UART(1, baudrate=115200, pins = ('P21', 'P20'), timeout_chars=2000) with open('/flash/pliki/mon','ab') as f: while True: data = uart.read(25) print(".") if data is not None: f.write(data) else: break f.close()
The f.close() is still there, but not needed due to the with... clause. The file system has an internal 4k buffer, unless that is full or the fiel is closed, nothing will be written. You should also not print the data, because that also consumes time. If that does not work, you'll need a handshake protocol between sender and receiver.
@robert-hh I have managed to read and write a jpg file using lopy and store it on SD after assigning different pins for uart.
When i try to do the same with the same jpg and store it on flash the file is being corrupted, number of bytes is different and somewhere in the middle of a file binary data are totally different then those of original file, i am using this code:
from machine import UART import pycom import time from machine import SD import os #sd = SD() #os.mount(sd,'/sd') #os.listdir('/sd') uart = UART(1, baudrate=115200, pins = ('P21', 'P20'), timeout_chars=2000) while True: data = uart.read(25) print(data) if data != None: with open('/flash/pliki/mon','ab') as f: f.write(data) f.close()
What may be causing file corruption?
@crumble unfortunately it was a pin problem, when connected to pins 21 and 20 as serial TXD and RXD data is stored on SD without any problem
@crumble If Pin conflict is the issue, one can reassign the UART Tx/Rx to other Pins, usign the uart.init() method
- Have you switched it off and on againt? Or better have you checked that SD card is formatted in FAT 16 or 32 and can be written by other devices?
- have a look on the pinout PDF. UART 1 and SD card handling seems to share the same pins. Maybe you cannot use UART 1 and SD card at the same time. Try to close the UART before writing to the SD card.
Uh, I hope 2) is not the problem. Otherwise I will run with P10 into the same trap.
@monersss Try to get Atom out of the way, since it may introduce problems of its own. Use a simple a terminal emulator like putty or screen, copy your script to the target device usiong ftp and try it there.
@crumble no this is not a problem, i was actually trying to write anything to sd and it does not work, even when i try to write (data) i am getting 20 bytes once and than OSError Erro 5 EIO, so i am unable to write anything to my sd running script from Atom
@monersss said in Receive data on lopy through serial:
f.write('data')
remove the ' around data. You write the string 'data' multiple times in your file. You shall see this, if you open the file in a text editor. Remove the ' and you will write the content of your data variable.
@robert-hh I have updated my code and i am sending a jpg over chunks of data to my lopy, transmission works if i do it to flash, unfortunately SD card write does not work, heres the code:
import pycom import time from machine import SD import os sd = SD() os.mount(sd,'/sd') os.listdir('/sd') uart = UART(1, baudrate=9600, timeout_chars=2000) while True: data = uart.read(20) print(data) if data != None: with open('/sd/mydatas','ab') as f: f.write('data') f.close()
I have updated my firmware and atom release hoping that it will solve the problem, but that is not the case. When i open the file in 'ab' on sd using console everything is ok. Are you aware of any bugs that can cause this?
@monersss That is most likely because the indentation is wrong. If you see data in the print statement, then it shoud work with:
import pycom import time from machine import SD import os sd = SD() os.mount(sd, '/sd') uart = UART(1, baudrate=9600, timeout_chars=2000) while True: data = uart.read(2000) print(data) if data != None: with open('/sd/mydat','ab') as f: f.write(data) f.close()
Using 'ab' causes data to be appended to the file.
@monersss said in Receive data on lopy through serial:
@robert-hh sorry for the typo, i cannot save the file on SD, the card is empty after running the code:
while True:
data = uart.read(2000)
print(data)
if data != None:
with open('/sd/mydat','wb') as f:
f.write(data)
f.close()
Yes, because all you do inside the loop is reading from the uart and printing the content. Because your loop will never end, you will not reach the part where you write it to disk.
There will be multiple errors:
- You will never write your data to the sd card. You read it only in the while loop. The other part will never be reached.
- After it booted your LoPy will have around 30-64Kb of free memory. But not in one chunk. It will be scattered in small parts, depending on what you have done before. So you have either
- to split up your image into smaller chunks
- request a fix data block in the booting process as soon as possible. Than you read the from the uart into this fix buffer
- use a *Py with 3MB memory
At best you send the image in smaller chunks, so your LoPy can handle the amount of data. Therefore you will need some sort of protocol around it. Like:
start sending image 'FileName' 23123bytes:
So your read at first a line with a string. You parse the name of the file and its length.
You create the file. Read 90times a small chunk of 255bytes and append it to this file. At last you do this for the remaining 173 bytes and close the file.
At the beginning it will be easier to send the controling line as 3 lines. something like first line "send image" followed by two lines for file name and file length. So you work around string parsing and you will need only read, compare and convert to integer.
@robert-hh sorry for the typo, i cannot save the file on SD, the card is empty after running the code:
import pycom import time from machine import SD import os sd = SD() os.mount(sd, '/sd') uart = UART(1, baudrate=9600, timeout_chars=2000) while True: data = uart.read(2000) print(data) if data != None: with open('/sd/mydat','wb') as f: f.write(data) f.close()
@monersss First of all, there is a typo in the uart = UART(... statement. It should be 115200, not 11520.
But, if you are using a LoPy 1, the total available heap space is about 50k, which may be fragemented. It is highly unlikely, that you can allocate a 30k buffer. Try using a smaller buffer, like 2k bytes and write these to SD (or just count the number of received bytes).
@crumble I have updated my code:
import pycom import time from machine import SD import os uart = UART(1, baudrate=11520, timeout_chars=2000) while True: data = uart.read(30000) if data != None: with open('/flash/mydati', 'wb') as f: f.write(data) f.close()
I did not change anythng in 'with open..' as for now i am only testing how the tramsfer goes so i do not care about overwriting the data.
i am sending 23 KB data to lopy and i am arriving at an error:
memory allocation failed, allocating 30001 bytes.

First XSLT Function
YouTube function
Let’s see what we want to create and then make it. Simple steps at a time; this might just be the first XSLT function you are creating.
Our aim here is what you see in the screenshot of a page on my C1 CMS demo site. This part of the template shows two content areas. The one area has pure content…
Figure 1: Showing pure content
…while the other one shows the YouTube video.
Figure 2: Showing a YouTube video inline
So we want editors to be able to add these to their page. We need to make it simple for them to insert these content elements anywhere they want to. If you don’t want the editors to have that much freedom in where to insert and play videos on the pages, you can consider using datatypes - a little more on that later!
Below is the same page in the manager: the template with three content areas the editor can supply content for.
Figure 3: Block 1 contains nothing but HTML
And Block 2 has the function inserted to play the YouTube video. This is what you will be able to create in a few minutes after you study this document!
Figure 4: Block 2 includes a YouTube video
Note: In my design the blocks have a fixed height; that is why the content below the function is not visible. I have just left it so in here to make clear that this function can just go anywhere on a page between content elements etc.
If you do the preview, you will see the video again as in the first screenshot.
How to embed a YouTube video
There are two ways to go with YouTube videos: link or embed. We want to play the video on our site, not just link to it. (An editor can do that just by supplying a hyperlink but that is boring.) So visit the YouTube website and find the code to embed a video on your site.
On the YouTube site, when having found a video, now get the embed code.
Figure 5: Video on YouTube
Here is the code copied straight from the site:
<object width="425" height="344"><param name="movie" value=""></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>
Listing 1: The Embed code from the YouTube website
Have a look at the code: which code is standard and which differs per video? If you’re not sure, get another video, get its embed code and compare the two.
Let’s beautify the code a bit for readability:
<object width="425" height="344"> <param name="movie" value=""></param> <param name="allowFullScreen" value="true"></param> <param name="allowscriptaccess" value="always"></param> <embed src="" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"> </embed> </object>
Listing 2: The same code formatted for readability
We can see that it has an <object> element with some parameters and an <embed> element.
It looks duplicated, which it is. This is how it takes care of different browsers.
Using the YouTube code from C1 CMS
Let’s first copy this code to a blank page in C1 CMS. Be sure not to copy the word stuff into your browser. This is code not content.
If you copy and paste it, or better insert as the Word, it will come out as text. What we need is it keeping HTML tags, not content on a page. Therefore, we need to paste it in as code.
- Select to the Content perspective in C1 CMS
- Create a new page or edit an existing page
- Select the Content tab
- Switch to the Source code view (the Source button right on top of Visual editor)
- Paste the HTML in
Figure 6: HTML pasted in the Source view
Now click the Preview tab. Oh no! An error… Too bad it does not work!
Don’t be put off immediately. I agree that they are nasty and can be really cryptic but always try to find something in that error message!
Figure 7: An error displayed in the Preview
It is complaining about ‘=’ at Line 4 Position 60 where it expects a ‘;’. Let’s see if we can fix it there. At Line 4 we see a lot of equal signs. Position 60 must be somewhere at the end:
value="
There we see “CVvC80xoWmI&hl=en&fs=1”. Well this is “&hl=” it doesn’t like.
It expects something like “&code;” and it reads something like “&code=” which is not allowed in XHTML, and C1 CMS validates your output for that and, therefore, complains.
In order to ensure validity of strings like that, ampersands must be expressed themselves as an entity reference, i.e. "&” For example:
value="
Note: Please refer to Using Ampersands in Attribute Values (and Elsewhere) for more information.
The strange string of characters just before the ampersand “CVvC80xoWmI” is actually the unique YouTube video code. If you look at different <embed> elements, you will see that this one changes for each video. If you change anything there you will see either no video or another one. It is the unique way to specify which video you want to see. That is exactly what we need later on, and it is what we will have the editors specify. So leave that code intact for now.
Usually you will just try to take out pieces that cause problems and see if you can still get it to work. So I took out the “&hl=en&fs=1” part and then it started complaining about another line.
Yes, indeed, there you find the similar one in the <src> value of the <embed> element. Clear them both out and the preview works now! It plays your video (just give it a little bit of time to load it from YouTube)
I am leaving you with the following working code:
<object width="425" height="344"> <param name="movie" value=""></param> <param name="allowFullScreen" value="true"></param> <param name="allowscriptaccess" value="always"></param> <embed src="" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"> </embed> </object>
Listing 3: The modified code that works now
This code works, and to play another video, you have to change that video code. So we have found the main variable part in here: “CVvC80xoWmI”. So if we want to play a YouTube video, we need to put in all this HTML code and the code of the video we want to see.
To put in some HTML code on a page you can use an XSLT function. This is what we will make now.
To put in an input variable for the video code we can create an input parameter in this function.
You’re still here, not feared away by that complex error, good! It will not get any more complex than that!
We will now create a XSLT function, which will write some HTML, the HTML we have just managed to get correctly rendered by C1 CMS with the page preview.
To create a new function, select the Functions perspective.
There you can see the list of functions available on your site. It might be empty or list a whole lot of them depending on your site implementation and add-ons installed. I have a bunch of them.
Now you will create the function by right clicking in the XSLT Function part of the Functions navigator and clicking Add Function in the context menu.
Figure 8: About to add an XSLT function
Think well about the name for a function! When editors will want to add a YouTube video, they must insert the function from this list of functions. Giving a good name will make the function easier to find and group with similar functions.
You might consider using different namespaces. If you are creating the function as a partner, you might have a namespace of “Partner name functions”, or for a specific customer - “Customer name functions”. You can see that C1 CMS uses its own namespace as well: all the add-ons are under within the “Composite” namespace, as well as items in other perspectives such as “Media”. This is important; but for now we will not go deeper into this.
Creating an XSLT function
To create a new function:
- Select the Functions perspective
- Select the XSLT functions in the navigator’s tree
- Click Add Function
- Specify the name
- Specify the namespace
- Click OK
I named the function MyYoutube and entered “Demo.Media” as the namespace. Meaning you will have a namespace called Media below the already existing Demo namespace.
Note: namespaces are case-sensitive, so if you type “demo.media”, you will have two “demo”namespaces: “Demo” and “demo”, which might not be your idea of ordering functions.)
Output type XHTML
Leave the output type as XHTML, so that we will have XHTML generated. The other choice is XML. Putting it on XHTML will make the function available in the Insert Function list of Visual Editor. In most cases, you will be creating XHTML functions.
When going much more advanced on, you might want to create XML that is used in other functions; in that case, you’ll have to change the output type.
Figure 9: Editing an XSLT function
The function is created. The namespace now shows in the function tree.
An XSLT function editor view consists of several tabs. It opens on the Template tab, which shows the XSLT. This is where you specify the output of the function. Here you will add the XHTML and any XSLT needed to render XHTML. We will get to the other tabs later.
Let’s start simple, with “hello world”. You can replace the entire inner <body> section with some of your html. Click on the Preview tab to see the result:
Figure 10: Previewing the XSLT function.
Smaller steps: inserting a new function
If you want to take smaller steps, you can now save this function and test it.
For the limited functionality it has now, it only shows “Hello World!” in my case.
To do so:
- From the Content perspective, edit a page,
- Switch to the Visual view if necessary
- Insert the function (Insert > Function)
- Then click to expand Demo.Media and you will see your function there.
- Select it and click OK.
Figure 11: Inserting the function
Now you can see the green box with your function’s name appeared on a page. Add some content above and below your function. Click Preview to see the result.
Figure 12: The function has been inserted
Okay, that works. Now let’s go back to the function again and add something better than just “Hello World!” to it.
Now remove “HELLO WORLD” and add that YouTube code we made earlier. Hopefully, you kept it in Notepad somewhere (Personally I use Notepad++, a free, very handy editor with many cool features, I often have multiple documents open in where I paste parts of code). Otherwise go back in this document to the proper section and copy it again.
- Copy the YouTube object embed code
- Paste the code in the <body> section of the XSLT template.
- Save the function.
If you took the smaller steps, you can switch to the Content perspective again. If you still have that page with your function open, you can click on the Preview tab again. This is a great way of testing your function on a page. Click back and forth from the function and content section (the same works well when modifying templates)
Figure 13: Pasting the YouTube HTML embed code in the function
But this will always show the same YouTube video. Now we need to make it dynamic. An editor should supply that video code. To do so, we can use the Input Parameters of a XSLT function.
- Click on the Input Parameters tab
- Click Add New (input parameter)
- Type “VideoCode” in the field name. This is the name of our variable, we need this later in the specific casing
- Specify the Label and Help fields to give more friendly names and explanation about what this input parameter is used for. For example, I have specified “Copy the move id code from YouTube in here ( like 64Nl7Mhnugo from)” in the Help field.
Figure 14: Adding an input parameter
In the Parameter type and values, you specify, of which type the VideoCode parameter is and what the value of the parameter will be, or better where we will get it from.
We need something like “CVvC80xoWmI” to fit in there, which is a string.
Let’s create a test value with that string in there:
- Click the Test value. Two windows will pop up.
- Click Set New.
- Select the function Composite | Constant | String. The function opens and shows that it has a parameter : Value)
- Specify the value for the String constant function by choosing Constant and then pasting our video code in.
Figure 15: Specifying the constant value –video code
- Click OK.
You see, you are using CMS functions and input parameters, just like you do with your own right now.
- Click the Preview tab.
Figure 16: Previewing the modified function
You can see our input parameter with the test value appearing in the preview. We will now get that parameter into the XHTML we have specified in the Template. This is where we need to do a little XSLT coding.
Learning the basics of XSLT
This document is not intended to teach you that; but it will give you some bits to start with.
XSLT is quite complex to master but it is quite easy to change if you learn the basics. XSLT works very well on reuse. (Installing add-ons from our package server will provide you with good examples, although some are aimed at a more complex level.)
Once you have gathered some XSLTs, do a lot of googling and practicing in, for example, the free XRay XML Editor. You will learn a lot about XSLT. Focus on learning the basics, see how XSLT looks. You don’t have to be able to write XSLT from scratch nor understand it fully to use and modify it! You will often be able to use a complex XSLT by only changing some simple bits and pieces!
Learn the XPath, learn the template basics and spot the xsl:value-of bits. These are the basic things you need to change in XSLTs. Paste the input XML from your functions into your editor (XRay or better XMLSpy) and code the XSLT in there until you are satisfied, then paste the XSLT back in here.
You will not learn anything specific to C1 CMS here. Just open standards XML and XSLT that you can reuse in many other different projects and products. You can also consult other people knowing nothing of C1 CMS but knowing XSLT.
To start learning XSLT I have created a page on a personal site with some links and tips to resources and other interesting things:.
Getting the video code variable with XSLT
As was said, we will not try to teach you XSLT in here, so here we go with only short bits.
We have <in:paramCVvC80xoWmI</in:param> which needs to go in our XHTML.
Create a variable in XSLT and set the value with our XML using XPath query:
<xsl:param
Create the $videocode variable and select the value from our <in:inputs …> <in:…
Now to refer to variables in XSLT, you use something like this:
<xsl:value-of <xsl:value-of
With @ you are referring to XML attributes, with $ you are referring to XSLT variables.
If you want a variable within an XHTML element you will use the {$variable notation}
<strong><xsl:value-of</strong> <img src="{$variable}"/>
So to put the $videocode in the right spot, you will get to
<param name="movie" value="{$videocode}" />
The same counts for:
<embed src="{$videocode}" />
Test it using the preview, and see that the test value appears in the XHTML.
Voila! you managed to pull an input parameter into the output XHTML.
Okay, we managed to get an input parameter into our XHTML but it is still a constant value. We want the editors to specify the value for the videocode input parameter themselves.
This is what the default value is for. Until now we have been having the test value do this. This test value is not required in your function, but it can be handy for testing your function.
- Save your function.
- Switch to the Content perspective again.
- Preview.
Another error!
Instead of your function a [ Error in rendering ] appears! Nasty, but again don’t be put off! I’m actually ‘forcing’ these errors onto you to experience them and now to deal with them.
- Click on the error.
- Read the error in the popup
System.InvalidOperationException: Failed to get value for function 'Demo.Media.MyYoutube'. ---> System.ArgumentException: Missing parameter 'videocode' (type of System.String) at Composite.Functions.FunctionRuntimeTreeNode.GetValue(FunctionContextContainer contextContainer) --- End of inner exception stack trace --- at Composite.Functions.FunctionRuntimeTreeNode.GetValue(FunctionContextContainer contextContainer) at Composite.Renderings.Page.PageRenderer.ExecuteEmbeddedFunctions(XElement element, FunctionContextContainer contextContainer)
Listing 4: Error text
It reads like a lot of gibberish until you look a little bit closer and see the Missing parameter 'videocode' - hey! that is our variable! And it is missing. Right, we have not specified it yet. This is because we had already inserted our function before it had any input parameters.
Specifying input parameters for a function
Select the green box of your function on the page and click the function Properties button (or right-click the green box). Now you will have to specify your videocode.
Or better yet, remove your function and insert it again. When you insert it you will see that it automatically prompts for the missing videocode parameter. This is how the editors will now work with the function.
Figure 17: The function prompting for the required parameter
If there is no default value for a parameter, the function will automatically prompt for it. Note the names of the label and help. The videocode parameter is only used in the function itself. (Sorry, my help text is a bit confusing in here mentioning movie id, which should be a video code.)
You can also give a description for the whole function:
- Go to the settings tab of your function and type some text in there.
Figure 18: Providing a description for the function
Figure 19: The function shows its description
Generate documentation on functions
You can also generate automatic information of all your functions. C1 CMS will list all the descriptions, different parameters and help text for all the functions. So it is a very good practice to put some text in there for both your editors and for documentation.
To generate documentation for the functions:
- From the Function perspective, select All functions.
- Click Generate Documentation on the toolbar.
Similarly, you can do with All widget functions. You might as well generate on a single function or a namespace with a number of functions in a similar manner.
If you look at the object embed code, you see there are more parameters in there. You can also turn some of these parameters into input parameters of the function, just as you did with the videocode parameter.
<embed src="" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344" />
Listing 5: Parameters of the embed element
To something like:
<object width="{$width}" height="{$height}"> <param name="movie" value="{$videocode}" /> <param name="allowFullScreen" value="{$allowfullscreen}" /> <param name="allowscriptaccess" value="always" /> <embed src="{$videocode}" width="{$width}" height="{$height}" movie="{$videocode}" type="application/x-shockwave-flash" allowFullScreen="{$allowfullscreen}" allowscriptaccess="always" /> </object>
Listing 6: Implementing and using more parameters
You will have to think about what it would be nice to specify and what it would not.
More parameters do make your functions more flexible, but using too many of them will make them harder to use for editors. When implementing more parameters, it makes much sense to use default values so that the editors have to specify as fewer values as possible.
Also think about the types of parameters, don’t stick with strings, and use Booleans and integers where possible. It will prevent you from getting wrong values. C1 CMS is heavy on strong typing, preventing many errors and bugs before they might occur.
To create a default value, do the same as you did with the test value. It makes sense to do so except for the very minimum of default parameters that need to be specified by the user. By not specifying a default value, you force it to be specified by the user. In this case, I would specify default parameters for all the additional parameters you might choose to add and only leave the default value for the videocode unspecified.
More uses of an XSLT function without XML
We used all except for the Function calls tab. This tab is actually a very important tab you will use in many XSLT functions except for those functions where you don’t need to get data from the C1 CMS repository.
Most functions will use the Function calls section, they do so to get content from somewhere and then transform the xml with the XSLT. You will learn this in other documents on XSLT functions.
Templates and XHTML includes
Another good example of using XSLT functions, like we did without using the XML function, is for including XHTML in templates. When you work with templates, you will often find pieces of HTML, which are the same in several templates (like CSS and JavaScript includes, disclaimers, headers, footers, web statistics scripts, Google analytics etc). In those cases, it is good to put that HTML in one place, instead of having it in x places (x templates). It means that you will most likely put the HTML in the XSLT function (the way we started out) and add the function to the templates.
Some mightview this as a “downside”:
- they want to change something in the HTML
- open the template
- find out the code is not there
- need to go to the function and edit it there
But this it is not a downside!
It is true, you will have to take a few extra steps, but:
- you change it for all x templates at once
- it prevents you from forgetting a single template
- it prevents you from ending up with different pieces where you actually want is one!

If.
So is Python better than Perl, Bash, Ruby, or any other language? It’s really difficult to put that sort of qualitative label on a programming language, since the tool is so closely tied to the thought process of the programmer who is using it. Programming is a subjective, deeply personal activity. For the language to be excellent, it must fit the person using it. So we’re not going to argue that Python is better, but we will explain the reasons that we believe Python can be an excellent choice. We’ll also explain why it is a great fit for performing sysadmin tasks.
The first reason that we think that Python is excellent is that it are a sysadmin, your work can pile up faster than you can unpile it. With Python, you can start writing useful scripts literally in hours rather than in days or weeks. that we consider Python to be an excellent programming language is that, while it lets you start simply, it also allows you to perform tasks that are as complex as you can imagine. Do you need to read through a logfile line by line and pull out some pretty basic information? Python can handle that..
Additionally, if you are able to perform complex operations, but the maintainability of your code suffers along the way, that isn’t a good thing. Python doesn’t prevent code maintenance problems, but it does allow you to express complex ideas with simple language constructs. Simplicity is a huge factor in writing code that is easy to maintain later. Python has made it pretty simple for us to go back over our own code and work on it after we haven’t touched it in months. It has also been pretty simple for us to work on code that we haven’t seen before. So the language, that is the language’s syntax and common idioms, are clear and concise and easy to work with over long periods of time.
The next reason we consider Python to be an excellent language is its readability. Python relies on whitespace to determine where code blocks begin and end. The indentation helps your eyes quickly follow the flow of a program. Python also tends to be “word-based.” By that we mean that while Python uses its share of special characters, features are often implemented as keywords or with libraries. The emphasis on words rather than special characters helps the reading and comprehension of code.
Now that we’ve outlined a few of Python’s benefits, we’ll show some comparisons of code examples in Python, Perl, and Bash. Along the way, we’ll also look at a few more of Python’s benefits. Here is a simple example, in Bash, of showing all the combinations of 1, 2 and a, b:
#!/bin/bash for a in 1 2; do for b in a b; do echo "$a $b" done done
And here is a comparable piece of Perl:
#!/usr/bin/perl foreach $a ('1', '2') { foreach $b ('a', 'b') { print "$a $b\n"; } }
This is a pretty simple nested loop. Let’s compare these looping mechanisms with a
for loop in Python:
#!/usr/bin/env python for a in [1, 2]: for b in ['a', 'b']: print a, b
Next, we’ll demonstrate using conditionals in Bash, Perl, and
Python. We have a simple
if/
else condition check here. We’re just checking
to see whether a certain file path is a directory:
#!/bin/bash if [ -d "/tmp" ] ; then echo "/tmp is a directory" else echo "/tmp is not a directory" fi
Here is the Perl equivalent of the same script:
#!/usr/bin/perl if (-d "/tmp") { print "/tmp is a directory\n"; } else { print "/tmp is not a directory\n"; }
And here is the Python equivalent of the script:
#!/usr/bin/env python import os if os.path.isdir("/tmp"): print "/tmp is a directory" else: print "/tmp is not a directory"
Another point in favor of Python’s excellence is its simple support for object-oriented programming (OOP). And, actually, the converse of that is that you don’t have to do OOP if you don’t want to. But if you do, it’s dead simple in Python. OOP allows you to easily and cleanly break problems apart and bundle pieces of functionality together into single “things” or “objects.” Bash doesn’t support OOP, but both Perl and Python do. Here is a module in Perl that defines a class:
package Server; use strict; sub new { my $class = shift; my $self = {}; $self->{IP} = shift; $self->{HOSTNAME} = shift; bless($self); return $self; } sub set_ip { my $self = shift; $self->{IP} = shift; return $self->{IP}; } sub set_hostname { my $self = shift; $self->{HOSTNAME} = shift; return $self->{HOSTNAME}; } sub ping { my $self = shift; my $external_ip = shift; my $self_ip = $self->{IP}; my $self_host = $self->{HOSTNAME}; print "Pinging $external_ip from $self_ip ($self_host)\n"; return 0; } 1;
And here is a piece of code that uses it:
#!/usr/bin/perl use Server; $server = Server->new('192.168.1.15', 'grumbly'); $server->ping('192.168.1.20');
The code that makes use of the OO module is straightforward and simple. The OO module may take a bit more mental parsing if you’re not familiar with OOP or with the way that Perl tackles OOP.
A comparable Python class and use of the class looks something like this:
#!/usr/bin/env python class Server(object): def __init__(self, ip, hostname): self.ip = ip self.hostname = hostname def set_ip(self, ip): self.ip = ip def set_hostname(self, hostname): self.hostname = hostname def ping(self, ip_addr): print "Pinging %s from %s (%s)" % (ip_addr, self.ip, self.hostname) if __name__ == '__main__': server = Server('192.168.1.20', 'bumbly') server.ping('192.168.1.15')
Both the Perl and Python examples demonstrate some of the fundamental pieces of OOP. The two examples together display the different flavors that each respective language provides while reaching toward its respective goals. They both do the same thing, but are different from one another. So, if you want to use OOP, Python supports it. And it’s quite simple and clear to incorporate it into your programming.
Another element of Python’s excellence comes not from the language
itself, but from the community. In the Python community, there is
much consensus about the way to accomplish certain tasks and the idioms
that you should (and should not) use. While the language itself may
support certain phrasings for accomplishing something, the consensus of
the community may steer you away from that phrasing. For example,
from module import * at the top of a module is
valid Python. However, the community frowns upon this and recommends that
you use either:
import module or:
from module import resource. Importing
all the contents of a module into another module’s namespace can cause
serious annoyance when you try to figure out how a module works, what
functions it is calling, and where those functions come from. This
particular convention will help you write code that is clearer and will
allow people who work on your code after you to have a more pleasant
maintenance experience. Following common conventions for writing your code
will put you on the path of best practices. We consider this a good
thing.
The Python Standard Library is another excellent attribute of Python. If you ever hear the phrase “batteries included” in reference to Python, it simply means that the standard library allows you to perform all sorts of tasks without having to go elsewhere for modules to help you get it done. For example, though it isn’t built-in to the language directly, Python includes regular expression functionality; sockets; threads; date/time functionality; XML parsers; config file parser; file and directory functionality; data persistence; unit test capabilities; and http, ftp, imap, smpt, and nntp client libraries; and much more. So once Python is installed, modules to support all of these functions will be imported by your scripts as they are needed. You have all the functionality we just listed here. It is impressive that all of this comes with Python without requiring anything else. All of this functionality will help you out immensely as you write Python programs to do work for you.
Easy access to numerous third-party packages is another real advantage of Python. In addition to the many libraries in the Python Standard Library, there are a number of libraries and utilities that are easily accessible on the internet that you can install with a single shell command. The Python Package Index, PyPI (), is a place where anyone who has written a Python package can upload it for others to use. At the time we are writing this book, there are over 3,800 packages available for download and use. Packages include IPython, which we cover in the following chapter; Storm (an object-relational mapper, which we cover in Chapter 12, Data Persistence); and Twisted, a network framework, which we cover in Chapter 5, Networking—just to name 3 of the over 3,800 packages. Once you start using PyPI, you’ll find it nearly indispensible for finding and installing useful packages.
Many of the benefits that we see in Python stem from the central
philosophy of Python. When you type
import
this at a Python prompt, you will see The Zen of
Python by Tim Peters. Here it is: statement isn’t a dogmatic imperative that is strictly enforced at all levels of development of the language, but the spirit of it seems to permeate much of what happens in and with the language. And we have found this spirit to be a beautiful thing. This is perhaps the essence of why we choose to use Python day after day. This philosophy resonates within us as what we want and expect from a language. And if this resonates with you, then Python is probably a good choice for you as well.
If you justpicked up this book in a bookstore or are reading an introduction online somewhere, you may be asking yourself, how hard it is going to be to learn Python and if it is even worth it. Although Python is catching on like wildfire, there are many sysadmins who have been exposed to Bash and Perl only. If you find yourself in this category, you should take comfort in knowing that Python is very easy to learn. In fact, although it is a matter of opinion, Python is considered by many to be the easiest language to learn and teach, period!
If you already know Python, or are a programming guru in another language, you will probably be able to jump right into any of the following chapters without reading this intro and immediately start being productive using our examples. We made a concerted effort to create examples that will actually help you get your job done. There are examples of ways to discover and monitor subnets automatically with SNMP, to convert to an interactive Python shell called IPython, to build data processing pipelines, to write custom metadata management tools with object-relational mappers, to perform network programming, to write command-line tools, and much more.
If you are coming from a shell programming/scripting background, though, don’t worry at all. You, too, can learn Python quite easily. You need only motivation, curiosity, and determination, the same factors that led you to pick up this book and look at the introduction in the first place.
We sense there are still a few skeptics out there. Maybe some of the things you have heard about programming have scared you. One common, and horribly false, misconception is that only some people can learn to program, and they are a mysterious and elite few. The frank truth is that anyone can learn how to program. A second, equally false, misconception is that earning a computer science degree is the only way a person can truly become a software engineer. But some of the most prolific software developers do not have engineering degrees. There are people with philosophy, journalism, nutritional science, and English degrees who are competent Python programmers. Having a degree in computer science is not a requirement to learn Python, although it certainly doesn’t hurt.
Another funny, and false, misconception is that you must have started to program in your teenage years, or you will never learn to program. While this makes people who were lucky enough to have someone in their life that encouraged them to program at a young age feel good, it is another myth. It is very helpful to have started learning programming at a young age, but age is not a requirement to learn Python. Learning Python is most certainly not a “young person’s game,” as we have heard some people say. There are countless cases of developers who learned to program in their late 20s, 30s, 40s, and onward.
If you have gotten this far, we should point out that you, the reader, have an advantage many people do not. If you decided to pick up a book on Python for Unix and Linux system administration, then you most likely know something about how to execute commands from a shell. This is a tremendous advantage to learning to become a Python programmer. Having an understanding of the way to execute commands from a terminal is all that is required for this introduction to Python. If you truly believe you will learn how to program with Python, then read the next section immediately. If you don’t believe it yet, then reread this section again, and convince yourself it really is just a matter of getting your mind to understand you do have the power to learn how to program in Python. It is really that simple; if you make this decision, it will change your life.
This introduction to Python is going to be very different from any other one
we’ve seen, as it will use an interactive shell called IPython and a
regular Bash shell. You will need to open two terminal windows, one with
IPython and one with Bash. In every example, we will compare what we do in
Python with a Bash example. The first steps are to download the correct version of IPython for your platform
and install it. You can get a copy at. If for some reason,
you can’t get IPython to install you can also just use a regular Python
shell. You can also download a copy of the virtual machine that includes
all of the software for the book, as we have a copy of IPython
preconfigured and ready to run. You just need to type in
ipython, and you will get a prompt.
Once you have installed IPython and have an IPython shell prompt, it should look something like this:
[ngift@Macintosh-7][H:10679][J:0]# ipython Python 2.5.1 (r251:54863, Jan 17 2008, 19:35:17) Type "copyright", "credits" or "license" for more information. IPython 0.8.2 -- An enhanced Interactive Python. ? -> Introduction and overview of IPython's features. %quickref -> Quick reference. help -> Python's own help system. object? -> Details about 'object'. ?object also works, ?? prints more. In [1]:
In your Python terminal, type in the following:
In [1]: print "I can program in Python" I can program in Python
If you spend a lot of your day typing commands into a terminal, then you are used to executing statements and, perhaps, redirecting the output to a file or to another Unix command. Let’s look at the way we would execute a command in Bash and then compare that to the way it works in Python. In the Bash terminal, type the following:
[ngift@Macintosh-7][H:10701][J:0]# ls -l /tmp/ total 0 -rw-r--r-- 1 ngift wheel 0 Apr 7 00:26 file.txt
Example 1-1. Python wrapper for ls command
#!/usr/bin/env python #Python wrapper for the ls command import subprocess subprocess.call(["ls","-l"])
Now if you run this script, you will get the exact same output that
you would get if you ran
ls -ls from the command
line:
[ngift@Macintosh-7][H:10746][J:0]# ./pyls.py total 8 -rwxr-xr-x 1 ngift staff 115 Apr 7 12:57 pyls.py
Example 1-2. System information script—Python
#!/usr/bin/env python #A System Information Gathering Script import subprocess #Command 1 uname = “uname” uname_arg = “-a” print "Gathering system information with %s command:\n" % uname subprocess.call([uname, uname_arg]) #Command 2 diskspace = "df" diskspace_arg = "-h" print "Gathering diskspace information %s command:\n" % diskspace subprocess.call([diskspace, diskspace_arg])
Example 1-3. System information script—Bash
#!/usr/bin/env bash #A System Information Gathering Script #Command 1 UNAME="uname -a" printf “Gathering system information with the $UNAME command: \n\n" $UNAME #Command 2 DISKSPACE="df -h" printf "Gathering diskspace information with the $DISKSPACE command: \n\n" $DISKSPACE
If we look at both of the scripts, we see that they look a lot a like. And if we run them, we see that the output of each is identical. One quick note though: splitting the command from the argument is completely optional using subprocess.call. You can also use this syntax:
subprocess.call("df -h", shell=True)
As we mentioned earlier, importing a module like subprocess is
just importing a file that contains code you can use. You can create your
own module or file and reuse code you have written in the same way you
import subprocess. Importing is not magic at all, it
is just a file with some code in it. One of the nice things about the
IPython shell that you have open is its ability to inspect inside modules
and files, and see the attributes that are available inside them. In Unix
terms, this is a lot like running the
ls command inside
of /usr/bin. If you happen to be on a new system such
as Ubuntu or Solaris, and you are used to Red Hat, you might do an
ls of /usr/bin to see if tools
such as wget, curl, or lynx are available. If you want to use a tool you
find inside /usr/bin, you would simply type
/usr/bin/wget, for example.
Modules such as subprocess are very similar. With IPython you can use tab complete to look at the tools that are available inside a module. Let’s walk through subprocess using tab complete to look at the attributes available inside of it. Remember, a module is just a file with some code in it. Here is what a tab complete looks like with the subprocess module in IPython:
In [12]: subprocess. subprocess.CalledProcessError subprocess.__hash__ subprocess.call subprocess.MAXFD subprocess.__init__ subprocess.check_call subprocess.PIPE subprocess.__name__ subprocess.errno subprocess.Popen subprocess.__new__ subprocess.fcntl subprocess.STDOUT subprocess.__reduce__ subprocess.list2cmdline subprocess.__all__ subprocess.__reduce_ex__ subprocess.mswindows subprocess.__builtins__ subprocess.__repr__ subprocess.os subprocess.__class__ subprocess.__setattr__ subprocess.pickle subprocess.__delattr__ subprocess.__str__ subprocess.select subprocess.__dict__ subprocess._active subprocess.sys subprocess.__doc__ subprocess._cleanup subprocess.traceback subprocess.__file__ subprocess._demo_posix subprocess.types subprocess.__getattribute__ subprocess._demo_windows
Think of the special question mark syntax as a manpage query. If you want to know how a tool works in Unix, simply type:
man name_of_tool
When we look at this documentation, “Docstring” is the official term, we see an example of the way to use subprocess.call and a description of what it does.
You now have enough information to call yourself a Python programmer. You know how to write a simple Python script, how to translate simple scripts from Bash and call them with Python, and, finally, how to find documentation about new modules and attributes. In the next section, you’ll see how to better organize these flat sequences of commands into functions.
In the previous section we went through executing statements one after another, which is pretty useful, because it means we were able to automate something that we would normally have to do manually. The next step to automating our code execution is to create functions. If you are not already familiar with writing functions in Bash or another language, then one way to think about functions is as miniscripts. A function allows you to create blocks of statements that get called in groups that live inside of the function. This is quite a bit like the Bash script we wrote in which there were two commands enclosed in a script. One of the differences between a Bash script and a function is that you can include many function scripts. Ultimately, you can have multiple functions that group statements together in a script, and then that group of statements can be called to run a miniprogram at the proper time in your script.
At this point, we need to talk about the topic of whitespace. In Python, a uniform level of indentation must be maintained in nesting code. In another language, like Bash, when you define a function you put brackets around the code inside of a function. With Python, you must indent the code inside of the bracket. This can trip up newcomers to the language, at first, but after a while it will grow on you, and you will realize that this encourages readable code. If you have trouble getting any of these examples to work interactively, make sure you refer to the actual source code to see the proper indentation level. The most common practice is to set a tab to indent exactly four spaces.
Let’s take a look at how this works in Python and Bash. If you still have the IPython shell open, you don’t need to create a Python script file, although you can if you like. Just type the following into the interactive IPython prompt:
In [1]: def pyfunc(): ...: print "Hello function" ...: ...: In [2]: pyfunc Out[2]: <function pyfunc at 0x2d5070> In [3]: pyfunc() Hello function In [4]: for i in range(5): ...: pyfunc() ...: ...: Hello function Hello function Hello function Hello function Hello function
We can do the same thing in a live Bash shell as well. Here is one way:
bash-3.2$ function shfunc() > { > printf "Hello function\n" > } bash-3.2$ for (( i=0 ; i < 5 ; i++)) > do > shfunc > done Hello function Hello function Hello function Hello function Hello function
In the Bash example, we created a simple function shfunc, and then called it five times, just like we did with the Python function earlier. One thing to notice is that the Bash example requires more “baggage” to do the same thing that Python does. Notice the difference between the Bash for loop and the Python for loop. If this is your first exposure to a function in Bash or Python, you should make some other functions in your IPython window before you continue.
Functions are not magic, and writing multiple functions interactively is a great way to take away the mystery if this is your first experience with them. Here are a couple of examples of simple functions:
In [1]: def print_many(): ...: print "Hello function" ...: print "Hi again function" ...: print "Sick of me yet" ...: ...: In [2]: print_many() Hello function Hi again function Sick of me yet
Now we have a few silly examples under our belt, in addition to the silly examples that you tried out on your own as well, right? So we can go back to the script we wrote that prints system information and convert those statements into functions. See Example 1-4, “Converted Python system info script: pysysinfo_func.py”.
Example 1-4. Converted Python system info script: pysysinfo_func.py
#!/usr/bin/env python #A System Information Gathering Script import subprocess #Command 1 def uname_func(): uname = "uname" uname_arg = "-a" print "Gathering system information with %s command:\n" % uname subprocess.call([uname, uname_arg]) #Command 2 def disk_func(): diskspace = "df" diskspace_arg = "-h" print "Gathering diskspace information %s command:\n" % diskspace subprocess.call([diskspace, diskspace_arg]) #Main function that call other functions def main(): uname_func() disk_func() main()
Given our experiments with functions, this converted example of our previous script that we simply placed these statements inside functions and then used the main function to call them all at once. If you are not familiar with this style, you might not have known that it is common to create several functions inside a script and then call them all with one main function. One of many reasons for this is that if you decide to reuse this script for another program, you can either call the functions independently or together with the main method. The key is that you decide after the module is imported.
When there is no control flow, or main function, then all of the code gets executed immediately when it is imported. This may be OK for a one-off script, but if you plan to create reusable tools, and you should, then it is a good practice to create functions that encapsulate specific actions, and then have a main function that executes the whole program.
For comparison’s sake, let’s convert our previous Bash system information script to use functions as well. See Example 1-5, “Converted Bash system info script: bashsysinfo_func.sh”.
Example 1-5. Converted Bash system info script: bashsysinfo_func.sh
#!/usr/bin/env bash #A System Information Gathering Script #Command 1 function uname_func () { UNAME="uname -a" printf "Gathering system information with the $UNAME command: \n\n" $UNAME } #Command 2 function disk_func () { DISKSPACE="df -h" printf "Gathering diskspace information with the $DISKSPACE command: \n\n" $DISKSPACE } function main () { uname_func disk_func } main
Looking at our Bash example, you can see it has quite a bit in common with its Python cousin. We created two functions and then called those two functions by calling the main function. If this is your first experience with functions, then we would highly recommend that you comment out the main method by placing a pound sign in front of both the Bash and the Python scripts and running them again. You should get absolutely nothing when you run both scripts, because the program should execute, but won’t call the two functions inside.
At this point, you are now a programmer capable of writing simple functions in both Bash and Python. Programmers learn by doing, though, so at this point we highly recommend that you change the system calls in these two Bash and Python programs and make them your own. Give yourself some bonus points if you add several new functions to the script and call them from a main function.
One problem with learning something new is that, if it is abstract, like calculus, for example, it is hard to justify caring about it. When was the last time you used the math you learned in high school at the grocery store? In our previous examples, we showed you how to create functions as an alternative to executing shell commands one after another in a script. We also told you that a module is really just a script, or some lines of code in a file. It isn’t anything tricky, but it does need to be arranged in a particular way so that it can be reused in another future program. Here is the point where we show you why you should care. Let’s import the previous system information scripts in both Bash and Python and execute.
Open the IPython and Bash windows if you closed them so that we can
demonstrate very quickly why functions are important for code reuse. One
of the first scripts we created in Python was a sequence of commands in a
file named
pysysinfo.py. In Python because a file is
a module and vice versa, we can import this script file into IPython. Keep
in mind that you never need to specify the
.py
portion of the file you are importing. In fact if you do this, the import
will not work. Here is what it looks like when we do that on Noah’s
Macbook Pro laptop:
In [1]: import pysysinfo
Here is the output from the IPython terminal:
In [3]: import pysysinfo_func
Now, if we go back to our IPython interpreter and import this new script, we should see this:
In [1]: import pysysinfo_func_2
In [2]: pysysinfo_func_2. pysysinfo_func_2.__builtins__ pysysinfo_func_2.disk_func pysysinfo_func_2.__class__ pysysinfo_func_2.main pysysinfo_func_2.__delattr__ pysysinfo_func_2.py pysysinfo_func_2.__dict__ pysysinfo_func_2.pyc pysysinfo_func_2.__doc__ pysysinfo_func_2.subprocess pysysinfo_func_2.__file__ pysysinfo_func_2.uname_func pysysinfo_func_2.__getattribute__ pysysinfo_func_2.__hash__
In this example, we can ignore anything with double underscores,
because these are special methods that are beyond the scope of this
introduction. Because IPython is also a regular shell, it picks up the
filename and the byte-compiled Python file with the
.pyc extension. Once we filter past all of those
names, we can see that there is a
pysysinfo_func_2.disk_func. Let’s go ahead and call
that function:
In [2]: pysysinfo_func_2.disk_func() Gathering diskspace information df command: Filesystem Size Used Avail Capacity Mounted on /dev/disk0s2 93Gi 89Gi 4.1Gi 96% / devfs 111Ki 111
Often, the point of writing a reusable module is so that you can take some of the code and use it over and over again in a new script. So practice that by writing another script that uses one of the functions. See Example 1-6, “Reusing code with import: new_pysysinfo”.
Example 1-6. Reusing code with import: new_pysysinfo
#Very short script that reuses pysysinfo_func_2 code from pysysinfo_func_2 import disk_func import subprocess def tmp_space(): tmp_usage = "du" tmp_arg = "-h" path = "/tmp" print "Space used in /tmp directory" subprocess.call([tmp_usage, tmp_arg, path]) def main(): disk_func() tmp_space() if __name__ == "__main__": main()
In this example, not only do we reuse the code we wrote earlier, but we use a special Python syntax that allows us to import the exact function we need. What’s fun about reusing code is that it is possible to make a completely different program just by importing the function from our previous program. Notice that in the main method we mix the function from the other module we created, disk_func(), and the new one we just created in this file.
In this section, we learned the power of code reuse and how simple it really is. In a nutshell, you put a function or two in a file and then, if you also want it to run as script, place that special if__name__ == "__main__": syntax. Later you can either import those functions into IPython or simply reuse them in another script. With the information you have just learned, you are truly dangerous. You could write some pretty sophisticated Python modules and reuse them over and over again to create new tools.

Ok. As the title says I tried many times to simply write a program that rewrites a file to remove null characters. I confirmed with a hex editor that the file in question has tons on null characters, on average about 1 of every 2 characters in null. So my last attempt:
#include <stdlib.h> #include <stdio.h> int main() { FILE *f = fopen("main2.c","r"); FILE *t = fopen("temp","w"); int c; int count = 0; while((c = fgetc(f))!=EOF) { if(c) { fputc(c,t); } else { printf("null found\n"); } } fclose(f); fclose(t); FILE *n = fopen("main2.c","w"); FILE *w = fopen("temp","r"); while((c=fgetc(w))!=EOF) { fputc(c,n); } fclose(n); fclose(w); }
I though if nothing else this should work perfectly. Instead it spits out a file with chinese characters.
Sorry for being so stupid but I'm feeling impatient right now. I guess I would like to know what I did wrong, an a correct example, maybe a much more concise and faster answer.

Adobe Photoshop CS6 Crack + Keygen [Win/Mac]
* **Versions**. Photoshop CS2 and CS3 are the most recent versions for the Macintosh, though there are also versions for Windows and other platforms. Versions are numbered according to the release date. Photoshop CS3 is not backward-compatible with Photoshop CS2, so you have to start with the newest version in order to open older projects. The latest Photoshop is currently CS5.5, although many third-party products use earlier versions of Photoshop for compatibility with versions of Photoshop earlier than CS3.
* **Main features**. With each new version of Photoshop there are major changes to the program, so use it to learn how to use the tool you need most. For example, the biggest change in Photoshop CS3 was the introduction of the Linked Layers, which allows users to work on a group of layered Photoshop documents and manipulate them all at once. Photoshop CS3 is also the first version of Photoshop to include a Content Aware Fill tool, which automatically fills in areas of photos that are masked out of a specific color.
* **Interface**. As it has evolved, Photoshop has had different interfaces. Each version of Photoshop has included a new interface, with Photoshop CS2 being the first version to use a toolbox interface. Photoshop CS3 and later use the Layout view, which lets you manipulate groups of layers as a single object. Photoshop CS4 also uses a Wacom tablet interface for working with layers, similar to drawing with a pencil. The Interface view in Photoshop CS5 makes the program look like a drawing program.
* **Plug-ins**. Photoshop CS3 introduced support for _plug-ins_, which are different programs that users can add to Photoshop to perform special tasks. Plug-ins are much easier than learning to use Photoshop’s own special features, as they are already specifically developed for particular purposes. You can use plug-ins in Photoshop without installing them as extensions, which is an extra step you would have to take with third-party plug-ins.
You can use Photoshop to create and edit raster images. It has no type of vector drawing capability for creating artwork for print.
Photoshop’s most basic tools are raster image editing tools. The drawing tools enable you to make your own art—but only if you are comfortable with a digital pencil or pen. Illustrator is more limited in the types of artwork it can produce. It’s a vector tool, and most digital work is done in vector files. You

A review of Tenderness: Nick’s love story, by Anne-Clare Nielson
I am a book lover to the extreme. Some may think I am crazy but I’m really not. That’s probably why I became a librarian. People tend to be a lot easier to get along with when you are willing to share your love of literature.
Nick and Esme’s love story is very much that – a story about love.
“What she’d wanted was a clean slate, a sudden opening up, a homecoming; rather than a castle built of memories and cobwebbed by the ghosts of the past. She wanted an ending, a happy one—but most of all she wanted Nick’s forgiveness.”
Esme’s love of Nick is dead serious. Even though she is not attracted to him, her love for him is strong. Nick however, has no idea how to reconcile with the past.
“But in the end Esme had grown tired of waiting, and had decided she’d get over it all by herself. Esme had wanted Nick’s forgiveness; she’d wanted to be in a new place where she could start over, build a new life; she’d wanted to get out of the past and into the future, and that only remained for the two of them to know.”
Tenderness is a good read. I liked the world building of the castle but there were moments where I could have done without it. I felt that it could have been more suspenseful without it.
“It was a meeting of two worlds, a collision of universes, two lives that had suddenly been brought together to gaze in wonder at something more vast and more incomprehensible than either could have imagined.”
“They had come to that place where the castle was nothing and they were everything.”
Tenderness is a love story. It has a bit of mystery to it as well and it’s a story about forgiveness.
“The castle was a monument to past pain, not a monument to the truth. But then again, she wasn’t the one who’d built it, was she? She was just where it had found her.”
Tenderness is a great

Auto-refresh Tableau Reader Dashboards (.twbx)Lance Dacey Mar 18, 2016 8:36 AM
I spent a few days trying to figure this out so I thought that I would share.
- I have 8 dashboards which I am refreshing connected to two separate data sources.
- I have fully automated the data download, modification, and consolidation tasks with Python and Windows Task Scheduler.
- The only manual task that I had to do every day was open each dashboard and refresh Tableau Extract (they are connected to a large .csv file)
My solution was to:
- Use the Python API to write a .tde file (by the way, if anyone could create a to_tde method in the pandas library I would be so grateful)
- I use the shutil library to copy this file (/tde_folder/dashboard.tde) to a dummy folder with the .twb and a /Data/Data.twb Files/ folder. The new .tde file goes inside the Data.twb FIles folder which is where the .twbx looks for the data
- Use a function and os.walk and ZipFile to zip this dummy folder (which contains the .twb and the new tde.). Credit goes to this post:
- Rename the .zip folder to a .twbx folder so Tableau will open it properly
Copy the new .tde with the latest data to the dummy location which mirrors the .twbx format (you can open a .twbx with 7zip and check it out):
shutil.copy2(extract_file, tde_location)
Function to zip the folder:
os.chdir('C:/Users/OneDrive//tableau_dashboards/')
def zipfolder(foldername, target_dir):
zipobj = zipfile.ZipFile(foldername + '.zip', 'w', zipfile.ZIP_DEFLATED)
rootlen = len(target_dir) + 1
for base, dirs, files in os.walk(target_dir):
for file in files:
fn = os.path.join(base, file)
zipobj.write(fn, fn[rootlen:])
zipfolder('zippedfile', 'thefolderyouarezipping')
exit
Change the .zip folder to a .twbx (and delete the old .twbx file if it exists):
if os.path.isfile('dashboard.twbx'):
os.remove('dashboard.twbx')
for filename in glob.iglob(os.path.join(dashboard_location, 'dashboard.zip')):
os.rename(filename, filename[:-3] + 'twbx')
Finally, I simply use shutil to copy the files to a shared folder and then email a notification to everyone using the wincom32 library and Outlook. 100% automated now. I am pretty pleased. Obviously, I would prefer to have Tableau Server but I am operating with just one license of Tableau Desktop Professional right now...

The functions used by map,
filter, reduce and a
list's sort method can
also be a special function called a lambda form.
This permits us to use special one-use-only throw-away functions without
the overhead of a
def
statement. A lambda form is
like a defined function: it has parameters and computes a value. The
body of a lambda, however, can only be a single expression, limiting it
to relatively simple operations. If it gets complex, you'll have to
define a real function.
map
filter
reduce
list
sort
Generally, it's clearer to formally define a function rather than
try to define a lambda form.
We can play with lambda forms by applying them directly as
functions to arguments.
>>>
from math import pi
>>>
print (lambda x: pi*x*x)(5)
78.53981633970
>>>
from math import pi
print (lambda x: pi*x*x)(5)
78.53981633970
This statement creates a
lambda
that accepts a
single argument, named
x
, and computes
pi*x*x. This lambda is applied to an argument of 5. It
computes the area of a circle with a radius of 5.
x
pi*x*x
Here's a lambda form used in the map function.
>>>]
This map function applies our
radius-computing lambda form to the values from 0 to 7 as created by the
range. The input sequence is mapped to the output
sequence by having the lambda function applied to each value.
range
Parameterizing a Lambda. Sometimes we have a lambda which -- in effect -- has two kinds
of parameters: parameters that are elements of a sequence being
processed by map, filter or
reduce function, and parameters that are more
global than the items of a sequence.
Consider this more complex example.
spins = [ (23,"red"), (21,"red"), (0,"green"), (24,"black") ]
betOn= "black"
print filter( lambda x, y=betOn: y in x, spins )
betOn= "red"
print filter( lambda x, y=betOn: y in x, spins )
First, we create four sample spins of a roulette wheel, and save
this list in a variable called
spins. Then we chose a particular bet, saving this in
a variable called betOn. If the given
betOn keyword occurs in any of the
tuples that describe all of the spins, the
tuple is kept.
spins
betOn
tuple
The call to filter has a lambda form that
uses a common Python hack. The filter function only
passes a single argument value to the function or lambda form. If there
are additional parameters declared, they must have default values; in
this case, we set the default to the value of our variable,
betOn.
Let's work through this in a little more detail.
As the filter function executes, it
enumerates each element from the sequence, as if it had a
for
s in spins:
clause. Each
individual item is given to the
lambda
. The
lambda
then does the evaluation of y in
x; x is a tuple from
the list (e.g., (23, "red")) and
y is a default parameter value, set to the value of
betOn (e.g., "black"). Every time the
y value actually appears in the
tuple x, ("black" in
(24,"black")), the tuple is selected to
create the resulting list from the filter. When
the y value is not in the
tuple x, the
tuple ignored
s
y in
x
y
"black" in
(24,"black")
This default parameter hack is required because of the way that
Python maintains only two execution contexts: local and global. The
lambda's execution takes place in a fresh local context with only its
two local parameter variables, x and
y; it doesn't have access to global variables. When
the lambda is created, the creation happens in the context where the
betOn variable is known. So we provide the extra,
global parameters as defaults when the lambda is created.
As an alternative to creating lists with
the filter function, similar results can be created
with a list comprehension. This is covered just after the following
material on reduce. | http://www.linuxtopia.org/online_books/programming_books/python_programming/python_ch20s06.html | CC-MAIN-2018-13 | refinedweb | 667 | 62.07 |
Build-Time Hooks¶
A package specifies custom commands in its
pkg.yml file. There are
three types of commands:
pre_build_cmds (run before the build)
pre_link_cmds (run after compilation, before linking)
post_link_cmds (run after linking)
Example¶
Example (apps/blinky/pkg.yml):
pkg.pre_build_cmds: scripts/pre_build1.sh: 100 scripts/pre_build2.sh: 200 pkg.pre_link_cmds: scripts/pre_link.sh: 500 pkg.post_link_cmds: scripts/post_link.sh: 100
For each command, the string on the left specifies the command to run. The number on the right indicates the command’s relative ordering. All paths are relative to the project root.
When newt builds this example, it performs the following sequence:
scripts/pre_build1.sh
scripts/pre_build2.sh
[compile]
scripts/pre_link.sh
[link]
scripts/post_link.sh
If other packages specify custom commands, those commands would also be
executed during the above sequence. For example, if another package
specifies a pre build command with an ordering of 150, that command
would run immediately after
pre_build1.sh. In the case of a tie,
the commands are run in lexicographic order (by path).
All commands are run from the project’s base directory. In the above
example, the
scripts directory is a sibling of
targets.
Custom Build Inputs¶
A custom pre-build or pre-link command can produce files that get fed into the current build.
Pre-build commands can generate any of the following:
.cfiles for newt to compile.
.afiles for newt to link.
.hfiles that any package can include.
Pre-link commands can only generate .a files.
.c and
.a files should be written to the
$MYNEWT_USER_SRC_DIR environment variable (defined by newt), or any
subdirectory within.
.h files should be written to
$MYNEWT_USER_INCLUDE_DIR. The
directory structure used here is directly reflected by the includer.
E.g., if a script writes to
$MYNEWT_USER_INCLUDE_DIR/foo/bar.h,
then a source file can include this header with:
#include "foo/bar.h"
Details¶
Environment Variables¶
In addition to the usual environment variables defined for debug and download scripts, newt defines the following env vars for custom commands:
These environment variables are defined for each process that a custom command runs in. They are not defined in the newt process itself. So, the following snippet will not produce the expected output:
BAD Example (apps/blinky/pkg.yml):
pkg.pre_cmds: 'echo $MYNEWT_USER_SRC_DIR': 100
You can execute
sh here instead if you need access to the
environment variables, but it is probably saner to just use a script.
Detect Changes in Custom Build Inputs¶
To avoid unnecessary rebuilds, newt detects if custom build inputs have changed since the previous build. If none of the inputs have changed, then they do not get rebuilt. If any of them have changed, they all get rebuilt.
The
$MYNEWT_USER_[...] directories are actually temp directories.
After the pre-build commands have run, newt compares the contents of
the temp directory with those of the actual user directory. If any
differences are detected, newt replaces the user directory with the
temp directory, triggering a rebuild of its contents. The same
procedure is used for pre-link commands.
Paths¶
Custom build inputs get written to the following directories:
bin/targets/<target>/user/pre_build/src
bin/targets/<target>/user/pre_build/include
bin/targets/<target>/user/pre_link/src
Custom commands should not write to these directories. They should use
the
$MYNEWT_USER_[...] environment variables instead. | https://mynewt.apache.org/latest/os/modules/extcmd/extcmd.html | CC-MAIN-2022-05 | refinedweb | 549 | 59.3 |
I have found that FSOUND_SetReserved does not work if the channel handle you use is no longer valid. Is this a bug?
This is the situation. I have started a sound playing on a channel, then I have called SetReserved( channelHandle, true ) to ensure the channel is safe.
Later on I discover the sound has stopped playing (by calling FSOUND_IsPlaying(channelHandle) so i decide to un-reserve the reserved channel. I call SetReserved( channelHandle, false ), which does not work. The channel remains reserved.
The only way I can work around this is to bitmask the channel handle to get the channel index (ie mask out the ref count bits), then call SetReserved( channelIndex, false ). This works ok.
Shouldn’t FSOUND_SetReserved still work on channel handles that aren’t valid, by extracting teh channel index and operating on that?
- Abandon22 asked 14 years ago
- You must login to post comments
So you are saying that we shouldn’t unreserve channels after they are stopped? Do they remain reserved or not if we do not call SetReserved(id, false)?
I get the following trace in my code:

[code:2roe4yvo]
bool
cSoundChannel::PlayStreamAndReserveNewChannel(void)
{
bool success = false;
m_Section.Lock();
{
m_GlobalPlayStreamSection.Lock();
{
m_channelId = FSOUND_FREE;
if(!m_Stream) { // Stream should not be NULL. ASSERT(false); } else { // Open it paused. { try { FMOD_TRACE(_T("FSOUND_Stream_PlayEx(FSOUND_FREE, m_Stream, NULL, true)\n")); m_channelId = FSOUND_Stream_PlayEx(FSOUND_FREE, m_Stream, NULL, true); } catch(...) { // Fmod dll crash. ASSERT(false); } } if(m_channelId == -1) { // No new channels. #if defined(_DEBUG) { ASSERT(false); } #endif } else { try { // Set it as reserved so no one else can steal it. FMOD_TRACE1(_T("FSOUND_SetReserved(%i, true)\n"), m_channelId); if(!FSOUND_SetReserved(m_channelId, true)) { // Couldn't reserve it (someone else got it). #if defined(_DEBUG) { ASSERT(false); } #endif } else { // Success. success = true; } } catch(...) { // Fmod dll crash. ASSERT(false); } } } } m_GlobalPlayStreamSection.Unlock(); if(!success) { const bool fadeout = false; StopPlaying(fadeout); }
}
m_Section.Unlock();
return success;
}
[/code:2roe4yvo]
i don’t want channels to be reserved all the time — i want to create a dynamic range of sound samples, where whenever i create a cSoundChannel, it opens a new channel, and then releases it when it’s done (or when the object is destroyed).
How do I release the channel automatically once the stream stops playing? I understand I can’t do this because the handle is no longer at that point?
try putting a sleep in your test code like so:
[code:2roe4yvo]
int c = FSOUND_PlaySound(FSOUND_FREE, samp1); FSOUND_SetReserved(c, TRUE); while (FSOUND_IsPlaying(c)) { Sleep(100); } FSOUND_SetReserved(c, FALSE); >> Sleep(1000); printf("\n\nreserved = %d\n\n", FSOUND_GetReserved(c));
[/code:2roe4yvo]
thanks for your help… 8)
To reproduce this, I constantly call my play function to keep playling random sounds one after another, and after about 10 minutes, i get an access violation, and the following debug output (including my trace):
[code:1pxokjie]
FSOUND_Stream_GetTime(m_Stream)
FSOUND_IsPlaying(1421354)
FSOUND_Stream_GetTime(m_Stream)
FSOUND_Stream_GetTime(m_Stream)
FSOUND_SetReserved(1896488, false)
FSOUND_Stream_Close(m_Stream)
First-chance exception in Photokeeper – Debug.exe (FMOD.DLL): 0xC0000005: Access Violation.
[/code:1pxokjie]
i can get the same result during normal operation, usually after like a half hour of testing with sounds on. might be a thread sync issue with fmod?[/code]
stack at the crash is:
[code:2ekuykl3]
FMOD! 0035714e()
FMOD! 003572be()
KERNEL32! 77e7d33b()
[/code:2ekuykl3]
this doesn’t happen on the main thread, but some other thread — the only thread with priority 11.[/code]
hey brett!
any ideas on this? i’m banging my head on the wall trying to figure out what is going on… your help would be much appreciated.
how thread-safe is fmod?
what is that fmod thread with priority 11 that seems to appear out of nowhere and then crash?
Thanks…
um ok i did some more experiementing… i found that if i don’t reserve/unreserve channels, the crash never occurs. so that’s it for me, but i still think you have a pesky little bug in there somewhere…
sorry about the overpostage.
Geez well that explains a lot! I was assuming that FMOD was threadsafe because it is really made for games, which are inherently multithreaded.

lck.django 0.8.4
Various common Django-related routines.
The source code repository and issue tracker are maintained on GitHub.
This package bundles some royalty free static images that are useful in almost every Django project:
-
Silk icons 1.3 by FamFamFam - requires attributing the author
-
Silk Companion 1 by Damien Guard - requires attributing the author
-
Country Flags by SenojFlags.com - requires using the following HTML:<a href="">Country flag</a> image from <a href="">Flags of all Countries</a>.
How to run the tests
The easiest way would be to run:
$ DJANGO_SETTINGS_MODULE="lck.dummy.settings" DJANGO_SETTINGS_PROFILE="test" django-admin.py test
This command runs the internal Django tests as well and that’s fine because there are monkey patches and other subtleties that should better be tested for potential breakage.
The dummy project is also used as an example of setting up a Django project. However, it seems Django tests are not happy with some changes to the settings so we’re using the test profile (which loads overrides from settings-test.py) to avoid that.
Change Log
0.8.4
- TimeTrackable models can now force marking fields as dirty with mark_dirty() and mark_clean() methods
0.8.3
- concurrent_get_or_create will now raise AssertionErrors if given either too many fields (e.g. not all of which are unique or compose a unique-together constraint) or too few (e.g. fields do not form a whole unique-together constraint). Non-unique fields should be passed in the defaults keyword argument if needed at object creation time.
- profile now implements automatic profile account synchronization by registering a post-save signal on User and creating an AUTH_PROFILE_MODEL instance. A management command for existing applications called sync_profiles has been created.
- Unit tests converted to unittest2 format
0.8.2
- fixed regression from 0.8.1: removed savepoint support since the updated concurrent_get_or_create fails miserably on MySQL due to dogdy savepoint support in MySQL-python
0.8.1
- concurrent_get_or_create based on get_or_create from Django 1.4.2
- namespace_package_support extended to cover django.utils.translation as well (previously namespace-packaged projects only worked with I18N if setup.py develop or pip install -e . was used to install them)
- dj.chain requirement bumped to 0.9.1 (supports more collective methods)
0.8.0
- lazy_chain moved to a separate dj.chain package. The old interface is thus deprecated and will be removed in a future version.
- activitylog updates: removed redundant user fields so it works again with ACTIVITYLOG_PROFILE_MODEL set to auth.User
- EditorTrackable doesn’t require overriding get_editor_from_request anymore if EDITOR_TRACKABLE_MODEL is set to a profile model instead of auth.User
- profile admin module includes a predefined ProfileInlineFormSet for inclusion of profile-tied models to the UserAdmin as inlines
- the dummy application now passes all internal Django unit tests in versions 1.4.0 - 1.4.2
0.7.14
- lazy_chain: the fix from 0.7.13 introduced a different kind of bug, reverted and fixed properly now. More tests included.
- flatpages now serve content in the default language if the language requested by the browser is unavailable.
- some internal cleanups
0.7.13
- lazy_chain: when iterating over a slice, the iterator fetched one item too many. It didn’t yield it back so the result was correct but if using xfilter() that caused unnecessary iteration.
- dj.choices requirement bumped to 0.9.0 (choices are int subclasses, unicode(choice) is now equivalent to choice.desc)
0.7.12
- namespace package support now works with Unicode literals in settings.py
- dummy app settings refinements: timing middleware moved down the stack because it uses the user session, WSGI app definition was wrong
0.7.11
- No code changes
- dj.choices requirement bumped to 0.8.6 (fully compatible with 0.8.5 and significantly improves ChoiceFields)
0.7.10
- BACKLINKS_LOCAL_SITES setting to control if all configured sites should be considered local upon backlink discovery
- More backlink fixes data model fixes to make it more cross-compatible with different backends
0.7.9
- Fixed backlink hash generation in activitylog
- activitylog accepts UTF-8 characters in User-Agent headers
- activitylog South migration #0002 now also works on backends with DDL transactions (e.g. Postgres)
0.7.8
- Fixed South support for custom fields (DefaultTags and MACAddressField).
0.7.7
South migrations supported across the board. For existing installations you should run:
$ python manage.py migrate APP_NAME 0001 --fake $ python manage.py migrate APP_NAME
where APP_NAME is activitylog, badges, common, flatpages, profile, score or tags.
uniqueness constraints in activitylog.models.Backlink and activitylog.models.UserAgent moved to separate hash fields to make MySQL happy. South migrations should handle schema evolution regardless of the backend you’re using..8.4.xml | https://pypi.python.org/pypi/lck.django/0.8.4 | CC-MAIN-2016-44 | refinedweb | 780 | 51.55 |
Internationalization
This document is for Django's SVN release, which can be significantly different from previous releases. Get old docs here: 0.96, 0.95.
Django has full support for internationalization of text in code and templates. Here’s how it works.
Overview USE_I18N is set to False, then Django will make some optimizations so as not to load the internationalization machinery. See the documentation for USE_I18N.
You’ll probably also want to remove 'django.core.context_processors.i18n' from your TEMPLATE_CONTEXT_PROCESSORS setting.
If you do need internationalization: three steps
-
Translation strings specify “This text should be translated.” These strings can appear in your Python code and templates. It’s your responsibility to mark translatable strings; the system can only translate strings it knows about.
In Python code
Standard translation., make-messages.py, won’t be able to find these strings. More on make-messages later.)
The strings you pass to _() or uget) whenever you have more than a single parameter. If you used positional interpolation, translations wouldn’t be able to reorder placeholder text.
Marking strings as no-op.
Lazy translation.
If you don’t like the. It’s a good idea to add translations for the field names and table names, too. This means writing explicit verbose_name and verbose_name_plural options in the Meta class, though:
from django.utils.translation import ugettext_lazy as _ class MyThing(models.Model): name = models.CharField(_('name'), help_text=_('This is the help text')) class Meta: verbose_name = _('my thing') verbose_name_plural = _('mythings')
Pluralization).
In template code|length as counter %} There is only one {{ name }} object. {% plural %} There are {{ counter }} {{ name }} objects. {% endblocktrans %}
Internally, all block and inline translations use the appropriate ugettext / ungettext call.
Each RequestContext has access to three translation-specific variables:
- LANGUAGES is a list of tuples in which the first element is the language code and the second is the language name (in that language).
- LANGUAGE_CODE is the current user’s preferred language, as a string. Example: en-us. (See “How language preference is discovered”, below.)
- LANGUAGE_BIDI is the current language’s direction. If True, it’s a right-to-left language, e.g: Hebrew, Arabic. If False it’s a left-to-right language, e.g: English, French, German etc.).
Working with lazy translation objects a couple of helper functions.
Joining strings:).
The allow_lazy() decorator.
2. How to create language files.
Message files,:
- The root django directory (not a Subversion checkout, but the one that is linked-to via $PYTHONPATH or is located somewhere on that path).
- The root directory of your Django project.
- The root directory of your Django app.:
make-messages.py -a
Compiling message files.
A note to translators
If you’ve created a translation in a language Django doesn’t yet support, please let us know! See Submitting and maintaining translations for the steps to take.
3. How Django discovers language preference in your settings file. Django uses this language as the default translation — the final attempt if no other translator finds a translation.
If all you want to do is run Django with your native language, and a language file is available for your language, all you need to do is set LANGUAGE_CODE.
If you want to let each individual user specify which language he or she prefers, use LocaleMiddleware. LocaleMiddleware enables language selection based on data from the request. It customizes content for each user.
To use LocaleMiddleware, add 'django.middleware.locale.LocaleMiddleware' to your MIDDLEWARE_CLASSES setting. Because middleware order matters, you should follow these guidelines:
- Make sure it’s one of the first middlewares installed.
- It should come after SessionMiddleware, because LocaleMiddleware makes use of session data.
- If you use CacheMiddleware, put LocaleMiddleware after it.
For example, your MIDDLEWARE_CLASSES might look like this:
MIDDLEWARE_CLASSES = ( a django_language key in the the current user’s session.
- Failing that, it looks for a cookie that is named according to your LANGUAGE_COOKIE_NAME setting. (The default name is django_language, and this setting is new in the Django development version. In Django version 0.96 and before, the cookie’s name is hard-coded. available, Django uses de.
Only languages listed in the LANGUAGES setting can be selected. If you want to restrict the language selection to a subset of provided languages (because your application doesn’t provide all those languages), set, make-messages.py will still find and mark these strings for translation, but the translation won’t happen at runtime — so you’ll have to remember to wrap the languages in the real ugettext() in any code that uses LANGUAGES at runtime.
The LocaleMiddleware can only select languages for which there is a Django-provided base translation. If you want to provide translations for your application that aren’t already in the set of translations in Django’s source tree, you’ll want to provide at least. Feel free to read this value in your view code. Here’s a simple example:.
Using translations in your own projects in the settings documentation,.
You can also run compile-message.py --settings=path.to.settings to make the compiler process all the directories in your LOCALE_PATHS setting..
The set_language redirect view
As a convenience, Django comes with a view, django.views.i18n.set_language, that sets a user’s language preference and redirects back to the previous page.
Activate this view by adding the following line to your URLconf:
(r'^i18n/', include('django.conf.urls.i18n')),
(Note that this example makes the view available at /i18n/setlang/.) if you’re using the Django development version.)
After setting the language choice, Django redirects the user, following this algorithm:
-.
You hook it up like this:
js_info_dict = { 'packages': ('your.app.package',), } urlpatterns = patterns('', (r'^jsi18n/$', 'django.views.i18n.javascript_catalog', js_info_dict), ).
You can make the view dynamic by putting the packages into the URL pattern:
urlpatterns = patterns('', (r'^jsi18n/(?P<packages>\S+?)/$', 'django.views.i18n.
Using the JavaScript translation catalog).

As a relatively new developer, and a complete lightweight when compared to the rest of the Komodo development team, I find myself sharing snippets, errors and diffs for review quite often. Since I like to share (Mom and Dad taught me well), I thought it was important to make it easier to share in Komodo. At one point, a Komodo user was limited to using kopy.io to do this, and only in limited areas of Komodo. In 10.2, we’ve extended Komodo to allow our users to share more easily and in more ways.
We wanted to add more endpoints (more kopy.ios), allow users to share text from more aspects of Komodos (logs, diffs, files, etc.) as well as allow users to more easily add their own custom endpoints without having to touch any of Komodo UI. We did this with two major additions:
1) A new “Sharing” SDK (I’ll explain)
2) Komodo + Slack integration (uses the above SDK to post content to Slack!)
The Share SDK
var share = require("ko/share");
The logical way to extend the existing UI with more “share points” (menu items to select an output) was to extend the existing kopy.io module’s UI integrations and move it into it’s own SDK. Thus
ko/share was born.
The share module now adds menus to the following source points in Komodo:
- Editor context Share menu (Right click your file or selected text > Share…)
- Dynamic toolbar share button
- Log file window (Help > Troubleshooting > View Log File)
- Any diff dialog
- The trackchanges diff panel
All of these interfaces have been augmented with a Share dropdown menu.
Register your Module
At this point you might be thinking “Hey neat Carey, you added another dropdown menu list to Komodo…so what?”
Good question! If it was just a drop down all over the place that would be boring, so next we needed to add items to this list for all output modules dynamically.
share.register(name, namespace, label);
Enter
share.register(). It takes a
name (e.g. “kopy”), a
namespace (e.g. “ko/share/kopy” in order to
require your module.), and a
label (e.g. “Share code on kopy.io”, which is the label shown in the menu list). Komodo uses CommonJS method of getting JS code and that requires a namespace (like the one mentioned above). A basic example you can follow to add your own namespace for your share implementation is as follows:
require.setRequirePath("myShareProject",""). The best method to do this would be to include your code in a Komodo Addon but that’s to big a topic to cover here. Ask for help in our forums.
Komodo then checks to make sure you implemented a
share function in your module that Komodo can call later (this is explained in more detail in the next section). It then cycles through all of the UI sources in Komodo we mentioned above and adds a new menu item for you.
Implement the Share Interface
require("ko/share/kopy").share(data, meta)
Above I mentioned a
share function that the
share.register method looks for. This is the one and only requirement of your share module–it must have a share function. This is the interface we use to pass content to your module.
The Data
The function should take a string of
data and an Object of
meta information. The
data string is the content that will be posted as text to the output source. For example, in the case of kopy.io,
data is the code displayed in the webpage:
#!/usr/bin/env python3 print "why is this broken??" print("oh...duh...it's Python 3")
The Meta
The
meta object holds basic meta information about the
data you want to post. You can expect an object as follows:
var meta = { langauge: "javascript", title: "MyFile.js" }
Your Share module can use this information as you see fit. For example, you can post a file to kopy.io and leave it up to kopy.io to figure out what your content might be (text, Javascript, Python?) or you can use the
language property and send that along in the API call sent to kopy.io.
Since this module is so new, we are open to ideas for additional properties in the meta object, so please let us know if you have any suggestions.
Slacking
var slack = require("ko/share/slack");
Sorry, no more source links. This stuff’s not open sourced.
Now that we have the Share module, the next step was to add some share endpoints. Kopy.io was a breeze since our lead Komodo Developer, Nathan Rijksen, had already written most of the necessary code back in Komodo 9.2.
Since our team and MANY MANY others use Slack on a daily basis, we chose to add Slack.
This project was a lot of firsts for me. I got to augment a Django Python server with a new API endpoint, do funky window management and event handling (imagine having to program your website by starting at the browser window then trying to access the loading page in a particular tab to trigger your onload event…FUN!), and trying to streamline a 100% async user experience. I even got to take a new service for a spin that Nathan added while I was building the Slack integration,
ko/simple-storage. Simple-storage allows you to persist information about your addon, Userscript, etc. and have it persist between Komodo restarts. This is the recommended way to persist information rather than the traditional
require("ko/prefs") method.
Django API Endpoint
In order for Komodo to post content to your various Slack Teams and Channels it needs to authenticate users. Slack has a system in place which requires you to have a server in the middle of the process to actually send the final key request to the Slack Auth servers.
I started writing this in Node.js since that seems to be the go-to for API servers these days. In the end though, I decided to build it on Django. We already write so much Python in Komodo and we have a few other services built on a Django server. Besides, I’ve already written a Node API server in class and have never touched Django. Get moderately good at a ton of stuff and never become an expert at anything…that’s my advice kids (with tongue firmly pressed against my cheek)!
Without going into too much boring detail, the server handles a request from Komodo with two temporary auth keys (one from Slack and one from Komodo), which are sent to another Slack authorization server that handles permissions. When that is returned from Slack, our server sends the new final auth key back to Komodo and it’s encrypted and saved to disk.
The Slack Panel
The panel that appears after you’ve authenticated and you’re picking a channel, message, etc. is plain. There doesn’t appear to be anything special about it. But that’s not true. What is of interest is that it’s built completely from the
ko/ui SDK, just like the Start Up Wizard (Help > Run first start wizard again). There is ZERO markup involved there.
Here’s a sample of what it looks like in the backend. You can copy and paste this code into the Komodo console to try it for yourself (View menu > Tabs & Sidebars > Console, or Ctrl (Cmd on OSX) + Shift + B then click the Console tab):
panel = require("ko/ui/panel").create({ anchor: require("ko/windows").getMostRecent().document.documentElement, attributes: { backdrag: true, noautohide: true, width: "450px", class: "dialog" } }); panel.open(); var options = { attributes: { placeholder: "Title", col: 120, flex: 1 }}; var title = require("ko/ui/textbox").create(options); panel.add(title);
All the fields that you fill out in the Slack integration panel are saved for use later using the new
ko/simple-storage I mentioned above. Let’s have a look at that, then I think we should call it a day on this blog…oh ps. you can get rid of that panel I got you to create on your screen by just writing
panel.close() in the JS console 😉
Simple Storage
ko/simple-storage is meant to replace anything
ko/prefs does that is not actually “preference” related as the standard storage for application, addon, or userscript information. It’s persistent and easier to use, which should make anyone customizing Komodo pretty happy.
Here’s a small sample of how it works.
var my_SS = require("ko/simple-storage").get("mine"); my_SS.storage.pizza = "It's so good it's scary, Carey!"; console.log("Is pizza good? "+my_SS.storage.pizza);
The
storage object is saved to disk and can be reloaded after a restart by using the same code. And when you’re done with it, you just
remove it.
var my_SS = require("ko/simple-storage").get("mine"); console.log("Is pizza still good? "+my_SS.storage.pizza + " Stop asking stupid questions."); require("ko/simple-storage").remove("mine");
Just open the Komodo Console(View menu > Tabs & Sidebars > Console, or Ctrl (Cmd on OSX) + Shift + B then click the Console tab) if you’d like to give it a try.
So that was a long blog…but I hope you found it useful and can take advantage of these great ways to share with Komodo. As my mother always said…sharing is caring!

SINGAPORE (ICIS news)--Saudi Arabian Oil Co (Aramco) is set to secure higher naphtha premiums for July to December 2007 contracts, citing bullish market trend and reduced supplies in the second half of the year, traders said on Thursday.
“Current market fundamentals are advantageous to the supplier. It doesn’t give existing contract buyers much room to negotiate for lower premiums,” one contract buyer with a Japanese trading company said.

It raised offers of A180 naphtha at a $25/tonne premium to Aramco pricing formula, Rabigh naphtha at $23/tonne premium, Jubail naphtha at $21/tonne premium and A310 naphtha at $20/tonne premium.
Buyers have balked at such lofty contract prices and most are still in talks with Aramco officials, where face-to-face negotiations are taking place in
But the final contract prices could be achieved early next week, when all the buyers have reached an agreement, they added.
“I would not be too surprised if one buyer agrees on the prices and others would have to follow suit. Aramco would just say take it or leave it,” a second buyer with a Japanese end user said.
Aramco had informed its existing contract customers earlier that it would trim its naphtha supplies slightly to
Aramco is establishing a $9.8bn refinery/petrochemicals complex at Rabigh via a joint venture with Sumitomo Chemical. Capacity from late 2008 will include 1.3m tonnes/year of ethylene and 900,000 tonnes/year of propylene.
Its targeted high premiums came on the heels of recently concluded high prices by Abu Dhabi National Oil Co (Adnoc) with South Korean buyers earlier this month.
Adnoc successfully raised its recently negotiated July 2007-June 2008 premiums, over its April 2007-March 2008 prices with no discounts given to any of its customers, buyers have said.

If both implementations define the same syntax (the same tags and
attributes with the same behaviour) in my opinion they shouldn't differ in
namespace.
The editor (i.e. the one who writes XSP pages or stylesheets)
won't/shoudn't care about the language of the XSP processor of a system.
In addition this would make it possible to exchange the editors work
between systems using different target languages.
(Besides, this would put some (little) preasure on the logicsheet
designers to keep there design clear and documented, so that different
implementations stay in sync. ;-)
Just my humble opinion!

How can I host multiple Flask Apps for Multiple Domains?
Using this guide I created a basic Flask App in Python. This worked well, and without nginx I could connect to it using my domain. The issue is, that this wasn't scaleable to multiple apps on one droplet. To do so, I tried this:
I connected my domain via the DNS Settings in Digital Domain, and linked my domain to to route to the IP. I did this by pointing an A record from my domain to my IP, and NS records to the Digital Ocean servers. Here are the screenshots:
Domain Host
Digital Ocean DNS Host
An example setup from the DNS
I fresh installed NGINX:
sudo aptitude install nginx
I made
/etc/nginx/sites-enabled/defaultthis:
upstream app_server_one { server 127.0.0.1:7000 fail_timeout=0; } upstream app_server_two { server 127.0.0.1:8000 fail_timeout=0; } server { listen 80 default_server; server_name: cloud.ajnin.me # [snip...] location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass; } } server { listen 80 default_server; server_name: cloud2.ajnin.me # [snip...] location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass; } }
I started my nginx server:
sudo service nginx start
I created my two apps (note how both run on separate ports). Both of these run separately with nginx on default:
app.py
from flask import Flask app = Flask(__name__) @app.route('/') def index(): return 'Cloud' if __name__ == '__main__': app.run(host='0.0.0.0', port=7000, debug=True)
app2.py
from flask import Flask app = Flask(__name__) @app.route('/') def index(): return 'Cloud2' if __name__ == '__main__': app.run(host='0.0.0.0', port=8000, debug=True)
I started my two apps:
sudo (nohup) python app.py & sudo (nohup) python app2.py &
Doing this, I got the Error 'This webpage is not available' from Chrome. Testing each server individually it works by typing the server ip, but running them together and connecting with the domain doesn't seem to work. Some people have suggested that I create a VirtualHost, but I'm not sure how I could implement that for this system. Would anyone be able to point me in the right direction to how I can make this work?
Thanks,
Aj.
(I would just like to appreciate the help @asb has done to help me do this. See his responses on this and this for more info)
UPDATE: Just wanted to note that going to my ip:port for each server works. The domains aren't routing to these ip:port combinations though.
UPDATE: This is the output for netstat -plunt
UPDATE: FIXED!
See for more info
@Ajnin123 could you elaborate more? I couldn't merge the gist and the digital ocean tut. Many thanks.

Consistently, one of the more popular stocks people enter into
their
stock options watchlist
at Stock Options Channel is Home Depot Inc (Symbol: HD). So this
week we highlight one interesting put contract, and one interesting
call contract, from the January 2015 expiration for HD. The put
contract our YieldBoost algorithm identified as particularly
interesting, is at the $67.50 strike, which has a bid at the time
of this writing of $1.59. Collecting that bid as the premium
represents a 2.4% return against the $67.50 commitment, or a 3.3%
annualized rate of return (at Stock Options Channel we call this
the
YieldBoost
).
Turning to the other side of the option chain, we highlight one
call contract of particular interest for the January 2015
expiration, for shareholders of Home Depot Inc (Symbol: HD) looking
to boost their income beyond the stock's 2.4% annualized dividend
yield. Selling the covered call at the $87.50 strike and collecting
the premium based on the $1.55 bid, annualizes to an additional
2.8% rate of return against the current stock price (this is what
we at Stock Options Channel refer to as the
YieldBoost
), for a total of 5.2% annualized rate in the scenario where the
stock is not called away. Any upside above $87.50 would be lost if
the stock rises there and is called away, but HD shares would have
to advance 10.7% from current levels for that to happen, meaning
that in the scenario where the stock is called, the shareholder has
earned a 12.6% return from this trading level, in addition to any
dividends collected before the stock was called.

Dealing with route params in Angular-5
It is quite common to have both the query and route parameters in any single page application. This post a quick tip sharing a little RxJS snippet that I wrote in order to read the query and route parameters at once. Before we talk about that, let us find out how to read any route/query parameters in your Angular 2+ application. There are multiple ways to achieve that.
Reading from the Snapshot
First and the simplest way to do that is reading them from the
snapshot of the active route i.e. inject the instance of
ActivatedRoute into your component’s constructor or pull it from the
Injector and read it from there i.e.
import { ActivatedRoute } from '@angular/router'; @Component({ selector: 'app-user-detail', templateUrl: 'user-detail.component.html' }) export class UserDetailComponent implements OnInit { constructor(private activeRoute: ActivatedRoute) { } ngOnInit() { const queryParams = this.activeRoute.snapshot.queryParams const routeParams = this.activeRoute.snapshot.params; // do something with the parameters this.loadUserDetail(routeParams.id); } }
But there is a little gotcha here. As the name
snapshot specifies, these parameters are from the snapshot of the route at the first load of the component. These values will be calculated for the first load of the component and they won’t change unless you reload the page.
Why could it be a problem? Well let’s say you had a list of users on the sidebar and clicking any user loads this user detail component. It would work fine for the first time i.e. when none of the details were openend and you clicked any user and loaded the details for the first time. Now let’s say you want to open the details of another user, if you try and click the other one, it won’t work. Why? because the component is already loaded, angular is smart and won’t reload the component; it will just change the route params, which won’t have any affect on the component because we read from the initial snapshot and so we don’t have access to the update routed params.
So how can we fix this? Well we can do that by adding a listener to the route params.
Reading via Subscriptions
As discussed above, the snapshot won’t get updated if we try to reload the current route with different route parameters. Good news! apart from the snapshot, active route also provides the query and route parameters in the form of observables. We can subscribe to those observables and thus whenever the route params might get changed we will get notified in our subscriber and so we can load the user details.
Here is how it would look like in code:
ngOnInit() { this.activeRoute.queryParams.subscribe(queryParams => { // do something with the query params }); this.activeRoute.params.subscribe(routeParams => { this.loadUserDetail(routeParams.id); }); }
Perfect! Now the query and route parameters are not bound to the snapshot and whenever you will click any user from the sidebar, the subscriber will get fired and the new details will be loaded.
Reading them at once
But let’s say that our situation has been a little changed and we need both the query and route params at once. We need to read one parameter from the query params and the other from the route params and we need to send them both in the
loadUserDetail API call. How can we do that?
The Dirty Way
The immediate solution that might come to your mind would be to nest the subscribers like below:
ngOnInit() { // Nest them together and this.activeRoute.queryParams.subscribe(queryParams => { this.activeRoute.params.subscribe(routeParams => { this.loadUserDetail(routeParams.id, queryParams.type); }); }); }
Or you might be tempted to write a varied version of this i.e. move these nested callbacks to a helper function and then pass it yet another callback accepting query and route parameters i.e.
ngOnInit() { this.readUrlParams((routeParams, queryParams) => { this.loadUserDetail(routeParams.id, queryParams.type); }); } readUrlParams(callback) { // Nest them together and this.activeRoute.queryParams.subscribe(queryParams => { this.activeRoute.params.subscribe(routeParams => { callback(routeParams, queryParams); }); }); }
none the less, still a dirty solution (). So how can we fix that? The answer is to use the functionality already provided by RxJS.
Use RxJS
RxJS is a really powerful library and you can do it in several different ways, but the one I like and find myself using the most is to use the
combineLatest operator by using which we merge the route and query parameters and have a single observable giving us both in a single object. Here is how our updated example would look like
import { ActivatedRoute } from '@angular/router'; // Add the observable and combineLatest import { Observable } from 'rxjs/Observable'; import 'rxjs/add/observable/combineLatest'; @Component({ selector: 'app-user-detail', templateUrl: 'user-detail.component.html' }) export class UserDetailComponent implements OnInit { constructor(private activeRoute: ActivatedRoute) { } ngOnInit() { // Combine them both into a single observable const urlParams = Observable.combineLatest( this.activatedRoute.params, this.activatedRoute.queryParams, (params, queryParams) => ({ ...params, ...queryParams}) ); // Subscribe to the single observable, giving us both urlParams.subscribe(routeParams => { // routeParams containing both the query and route params this.loadUserDetail(routeParams.id, routeParams.type); }); } }
And that wraps up this little post on dealing with URL parameters. Do you have any tricks of your own, feel free to share them in the comments section below. Also if you would like to learn more about RxJS, here is a nice little website that you may wat to check.

Parse::PerlConfig - parse a configuration file written in Perl
use Parse::PerlConfig; my $parsed = Parse::PerlConfig::parse( File => "/etc/perlapp/conf", Handlers => [\%config, \&config], );
This module is useful for parsing a configuration file written in Perl and obtaining the values defined therein. This is achieved through the parse() function, which creates a namespace, reads in Perl code, evals it, and then examines the namespace's symbol table. Symbols are then processed into a hash and returned.
The parse() function is exportable upon request.
Parsing is not a simple do("filename"). Instead the filenames specified are opened, read, eval'd, and closed. The justification for this being twofold:
I did not want surprises in what file was found; do("file") searches @INC.
I wanted to be able to insert lexicals for the code in the file to see. Being able to define variables without having them parsed back out (remember, the namespace is searched) is a nice feature.
Parsing (in this manner) requires a namespace. By default, the namespace is constructed by appending Namespace_Base to a unique identifier (currently, an encoded version of the filename, but don't rely on this). You can override this behaviour by specifying an explicit Namespace argument.
Prior to eval'ing the contents of a configuration file the lexical hash %parse_perl_config is initialized with several keys (documented below); if a Lexicals argument was given each of the lexicals specified are initialized.
There are a few caveats; lexicals specified in the Lexicals argument cannot override %parse_perl_config; keys specified in Lexicals cannot be code references, because code references cannot currently be reliably reconstructed; modifications to %parse_perl_config keys (other than Error, documented below) are discouraged, as the results are not defined.
The %parse_perl_config hash contains the following keys:
Making this key a true value will cause the error handler Error_eval to be called with the value.
The namespace the file is being evaluated in.
The name of the file being parsed.
A hash of the arguments passed to parse().
Once the namespace has been setup, and the code eval'd, it is then parse()'s job to go through the namespace's symbol table and look for "things". What it looks for depends on the Thing_Order and Symbols arguments.
After that, handlers are updated, and a hash reference of what was parsed out is returned.
parse() takes a list of key-value pairs as its arguments and adds them to an argument hash. If the first argument to parse() is a hash or array reference, it is dereferenced and used as if it were specified as a list. All elements following this argument are added to the arguments hash, and they override any settings specified by the reference.
This means the call:
parse( { Files => "/home/me/config.conf", Error_default => 'fwarn' }, Files => "/home/you/config.conf" );
causes parse()'s argument hash to consist of the following (ignoring default settings):
Files => "/home/you/config.conf", Error_default => "fwarn",
Simply replace the braces, {}, with brackets, [], and you get the same result. This makes it convenient to store commonly-used arguments to parse() in a hash or array, and efficiently pass these arguments to parse(), while still allowing a seperate Files argument for each call.
The below itemization of parse()'s arguments describes key-value pairs. Each item consists of a key name and a description of the expected value for that key.
The value description requires some explanation.
A single pipe, "|", indicates alternative values; only one of the values must be specified.
Values bracketed with "<" and ">" indicate that value is not literal, but figurative. So, in the case of <coderef>, you must specify a code reference (a closure or reference to a named subroutine), not the literal string "<coderef>". Values without such bracketing are literal.
Braces, {}, indicate a hash reference is required; brackets, [], indicate an array reference is required.
Below each key-value description is a description of the default setting, followed by a description of what the argument means.
default: none, this argument is required
This is the file or files you wish to parse. If a file cannot be parsed for any reason the entire parse is not abandoned, the file is simply skipped (after calling an appropriate error handling function).
Equivalent to Files <filename>.
default: none
By default, parse() simply returns a hash reference of symbol names and their values. Given a Handlers argument, parse() will add key-value pairs to each hash reference specified, and call each code reference specified with a single argument, the hash reference it returns.
Equivalent to Handlers <hashref>|<coderef>.
default: none
The key-value pairs in the specified hashref are made into lexical variables in the configuration eval. See the section on Parsing for further information.
default: '$@%&i*'
Specifies the default thing order for symbols parsed from each configuration file. See the section Things for further information.
default: false
If set to any true value the filehandle opened on the configuration file is untainted before evaling the code contained therein. Because this involves loading IO::Handle, which involves quite a bit of code, the option is turned off by default. You will get taint exceptions if you don't specify this option while running in
-T mode.
Also, as the namespace is currently constructed, having a tainted filename will cause the namespace name to be tainted, so it is also untainted. In the case of an explicitly specified Namespace value, it will also be untainted.
No other values are untainted. This includes any key-value pairs specified by the Lexicals argument; you must untaint those yourself, since there is no reasonable way for parse() to determine how best to untaint them.
default: empty hashref
This is an override for the Thing_Order argument above. The keys in the specified hashref are symbols you want parsed specially, the values the thing order (either a string or array reference). See the section Things for further information regarding thing order.
default: generated from Namespace_Base and a unique identifier
This option explicitly specifies the namespace the files are parsed in. See the section Parsing for further information.
default: Parse::PerlConfig::ConfigFile
Unless the Namespace argument is specified, the namespace a file is parsed in is generated by appending a cleaned up version of the filename to this setting. See the section Parsing for further information.
See the section Error Handling for further information.
"Things" (as taken from the Perl documentation, regarding the *foo{THING} syntax) are the Perl datatypes. These include scalars, arrays, hashes, subroutines, IO handles, and globs.
Anywhere a "things" argument is required you can specify one of two things; a string containing the special "thing" characters, or an array reference of each thing's actual name. The thing characters are as follows:
$ for scalar,
% for a hash,
@ for an array,
& for a subroutine,
i for an IO handle, and
* for a glob. The full name for each coincides with the full name for each datatype in their respective glob slots: SCALAR for a scalar, HASH for a hash, ARRAY for an array, CODE for a subroutine, IO for an IO handle, and GLOB for a glob.
parse() takes various Error_* and Warn_* arguments that determine how it handles any problems it encounters. Each argument can take one of several values.
The error handling specifed by Error_default in the case of an Error_* argument, or Warn_default in the case of a Warn_* argument, is used.
The error is ignored.
Results in a call to CORE::warn() with a trailing newline, but only if
$^W is set to a true value.
Like warn, but the warning is raised regardless of
$^W's value.
Results in a call to CORE::die() with a trailing newline.
The code reference will be called with a single argument, that of the error message. The error message is guaranteed to contain no trailing newlines (in case the code reference decides to die() or warn()).
There are various handler arguments. Unless otherwise specified, the default handler is used (Error_default's or Warn_default's value).
default: noop
The default warning handler.
Called just before a file is parsed to indicate parsing is about to begin.
Called with any warnings issued by the eval'd file.
default: warn
The default error handler.
Called if there is a problem with one of the arguments specified.
Called if a configuration file specified was discovered to be a directory.
Called if the open attempt on a configuration file fails.
Called if the variable $parse_perl_config{Error} is set in the configuration file, or if there was an eval error.
Called if there is a problem with a thing character or thing name in a thing argument (thing thing thing).
Called if an unknown reference is encountered in the Handlers argument.
Called if an invalid lexical name or a CODE reference value is encountered in the Lexicals argument.
Called if either the constructed namespace (using Namespace_Base) or a specified Namespace value is invalid. This may indicate an error in the construction of a namespace name (the generation of a unique identifier), but it's most likely you specified Namespace_Base or Namespace with invalid characters.
Due to the fact that the scalar slot in a glob is always filled it is not possible to distinguish from a scalar that was never defined (e.g.
@foo was, but
$foo was never mentioned) from one that is simply undef. Because of this, for example, if you have a thing order of
$@ and code along the lines of
$foo = undef; @foo = (); the 'foo' key of the hash will be an array reference, despite there being a scalar and
$ coming first in the thing order.

New release – WrightMap 1.2
Want to share your content on R-bloggers? click here if you have a blog, or here if you don't.
A (too long in the making) new version of WrightMap is now available on CRAN (Actually, version 1.2.1 is already up).
This new version includes a lot of features that have long been requested, including cut-point lines, alternative item displays (classical Wright Map look, histogram view), and differential item functioning plots among others.
We have updated the package tutorials on our website to reflect the changes to this version, and we will be publishing additional posts showing the new features.
We hope these changes can be of use to you, and we look forward to hearing your feedback!
Change log for this version:
Major changes:
wrightMap split into data handling and plotting, each of which is further split into person & item side. The data handling functions are further split by filetype and the plotting functions are split by plot types. For data handling, this is meant to make it possible to have item and person data of different filetypes. For plotting, this is meant to make the plotting function more flexible and make it easier to add different plot styles. Details:
wrightMap.default, wrightMap.CQmodel, wrightMap.character are now removed. There is only wrightMap.R, which calls the appropriate data handling and plotting functions
helper functions for data handling
parameter person.side accepts person plot functions personHist (default) and personDens
parameter item.side accepts item plot functions itemModern (default), itemClassic, and itemHist
API changes
the “type” parameter in wrightMap is now called “item.type” to avoid collision with the “type” parameter in the “plot” function.
For the same reason, the “type” parameter in fitgraph is now called “fit.type”
the “use.hist” parameter in wrightMap is deprecated. Create a histogram with person.side = personHist (default) and density with person.side = personDens
fitgraph and make.thresholds now explicitly include a version for numeric and matrix respectively. This should fix namespace problems for users who prefer to include external functions with :: notation.
New functions:
- plotCI
- difplot
- ppPlot
New features:
now possible to add points and ranges to person side
can easily add cutpoints on item side
added “classic” and “hist” item map
“throld” parameters added to make.thresholds and wrightMap, allowing for the calculation of thresholds other than .5
“alpha” and “c.params” added to make.thresholds and wrightMap, supporting the 2PL and 3PL models
label.items.cex and dim.lab.cex added to wrightMap to control label sizes
support for ConQuest4 added
“equation” added to CQmodel and wrightMap.CQmodel, to handle CQ output without a summary of estimation table
it is now possible to plot the person and item sides separately
Improvements:
wrightMap now remembers your original graphical parameters and restores them after drawing the map
fitgraph no longer calls a new window
better handling of generics
Bugfix:
Fixes to CQmodel on reading the #IO variance errors and included fix for the var/covar matrix on CQ3
Fixed a bug where thr.lab.pos couldn’t take a matrix
Fixed a bug where fitgraph.CQmodel assumed there was always a parameter called “item” in your table
Fixed a bug where CQmodel assumed there were always an error column in the RMP tables
wrightMap will no longer crash if the p.est parameter is null
Other notes:
- Removed some of the runtime. | https://www.r-bloggers.com/2016/03/new-release-wrightmap-1-2/ | CC-MAIN-2022-27 | refinedweb | 569 | 56.76 |
NAME | SYNOPSIS | DESCRIPTION | ATTRIBUTES | SEE ALSO
#include <floatingpoint.h>void string_to_decimal(char **pc, int nmax, int fortran_conventions, decimal_record *pd, enum decimal_string_form *pform, char **pechar);
#include <stdio.h>void file_to_decimal(char **pc, int nmax, int fortran_conventions, decimal_record *pd, enum decimal_string_form *pform, char **pechar, FILE *pf, int *pnread);
The char_to_decimal functions parse a numeric token from at most nmax characters in a string **pc or file *pf or function (*pget)() into a decimal record *pd, classifying the form of the string in *pform and *pechar. The accepted syntax is intended to be sufficiently flexible to accommodate many languages: whitespace value or whitespace sign value,where whitespace is any number of characters defined by isspace in <ctype.h>, sign is either of [+-], and value can be number, nan, or inf. inf can be INF (inf_form) or INFINITY (infinity_form) without regard to case. nan can be NAN (nan_form) or NAN(nstring) (nanstring_form) without regard to case; nstring is any string of characters not containing ')' or NULL; nstring is copied to pd->ds and, currently, not used subsequently. number consists of significand or significand efield where significand must contain one or more digits and may contain one point; possible forms are
digits (int_form) digits. (intdot_form) .digits (dotfrac_form) digits.digits (intdotfrac_form)
efield consists of echar digits or echar sign digits,.where echar is one of [Ee], and digits contains one or more digits.
When fortran_conventions is nonzero, additional input forms are accepted according to various Fortran conventions:
no Fortran conventions
Fortran list-directed input conventions
Fortran formatted input conventions, ignore blanks (BN)
Fortran formatted input conventions, blanks are zeros (BZ)
When fortran_conventions is nonzero, echar may also be one of [DdQq], and efield may also have the form
sign digits.
When fortran_conventions>= 2, blanks may appear in the digits strings for the integer, fraction, and exponent fields and may appear between echar and the exponent sign and after the infinity and NaN forms. If fortran_conventions== 2, the blanks are ignored. When fortran_conventions== 3, the blanks that appear in digits strings are interpreted as zeros, and other blanks are ignored.
When fortran_conventions is zero, the current locale's decimal point character is used as the decimal point; when fortran_conventions is nonzero, the period is used as the decimal point.
The form of the accepted decimal string is placed in *pform. If an efield is recognized, *pechar is set to point to the echar.
On input, *pc points to the beginning of a character string buffer of length >= nmax. On output, *pc points to a character in that buffer, one past the last accepted character. string_to_decimal() gets its characters from the buffer; file_to_decimal() gets its characters from *pf and records them in the buffer, and places a null after the last character read. func_to_decimal() gets its characters from an int function (*pget)().
The scan continues until no more characters could possibly fit the acceptable syntax or until nmax characters have been scanned. If the nmax limit is not reached then at least one extra character will usually be scanned that is not part of the accepted syntax. file_to_decimal() and func_to_decimal() set *pnread to the number of characters read from the file; if greater than nmax, some characters were lost. If no characters were lost, file_to_decimal() and func_to_decimal() attempt to push back, with ungetc(3C) or (*punget)(), as many as possible of the excess characters read, adjusting *pnread accordingly. If all unget calls are successful, then **pc will be NULL. No push back will be attempted if (*punget)() is NULL.
Typical declarations for *pget() and *punget() are:
int xget(void) { ... } int (*pget)(void) = xget; int xunget(int c) { ... } int (*punget)(int) = xunget;
If no valid number was detected, pd->fpclass is set to fp_signaling, *pc is unchanged, and *pform is set to invalid_form.
atof(3C) and strtod(3C) use string_to_decimal(). scanf(3C) uses file_to_decimal().
See attributes(5) for descriptions of the following attributes:
ctype(3C), localeconv(3C), scanf(3C), setlocale(3C), strtod(3C), ungetc(3C), attributes(5)

What do you think about the 45 mph speed limit on County Road 486? Marsha Romanik Riddle County Road 486 should be at least 55 mph. Jake Muetzel 50-55 mph should be the minimum, especially on those long roads. Kelly L. Graham I used to drive that stretch going to CF in Ocala (from Crystal River) and 45 mph seems too slow. Easy speed trap if they leave it at that speed. There are no homes around so not sure why they put it so low.

Erin Ewing 45 mph on CR 486 is ridiculous; its entirely too easy to speed. Its a wide road with less traffic than Hwy. 44, yet its limit is 15 mph slower. It makes no sense to me.

INSIDE Balfour moved for school board seat MIKEWRIGHT Staff writerPoliticians often say they make sacrifices for their role in public office. Citrus County School Board member Sandy Balfour, appointed to office in June by Gov. Rick Scott, can back it up. Balfour took a huge pay cut and moved from her Pine Ridge neighborhood to a single-wide mobile home in Homosassa to get the appointment. The house she and her husband of 34 years, Tom, shared since 1999 is for sale. And moving from an 1,800square-foot house to a mobile has meant some personal downsizing. This has been a forced weaning, Balfour said. Thats the way Im looking it. I have to really qualify the things that have value in my life. Its forced me to think down my personal property. Balfour, an unsuccessful candidate for superintendent of schools in 2012, quickly added her name to the list of applicants in early 2013 after newly elected board member Susan Hale resigned. Shortly after submitting her application, Balfour said she called the governors office to check on the procedure. She said a staffer told her she wouldnt even be considered for the position if she didnt live in District 4, which comprises the southwest Citrus communities of Homosassa and Sugarmill Woods. I was not going to be considered unless I was willing to move, she said. They wouldnt even look at my rsum. Balfour wanted the appointment, but she and Tom Sandra Sandy BalfourCitrus County School Board member, District 4.

The agency has moved its one-stop career center in Citrus County from Inverness to Lecanto. It will have an open house at the new location Feb. 10. Also this month, Workforce Connection will change its name as part of a new unified CareerSource Florida brand designed to enhance access to workforce services for job-seekers and businesses throughout the state. Beginning in early 2014, Workforce Connection will become CareerSource Citrus Levy Marion. Floridas 23 other workforce organizations will adopt CareerSource brands with similar regional locaters. Darlene Goddard, Report: US abortion rate at lowest since 1973 DAVIDCRARY AP national writerNEW YORK The U.S. abortion rate declined to its lowest level since 1973, and the number of abortions fell by 13percent between 2008 and 2011, according the latest national survey of abortion providers conducted by a prominent research institute. The Guttmacher Institute, which supports legal access to abortion, said in a report being issued Monday that there were about 1.06million abortions in 2011 down from about 1.2million in 2008. Guttmachers figures are of interest on both sides of the abortion debate because they are more up-todate and in some ways more comprehensive than abortion statistics compiled by the federal Centers for Disease Control and Prevention. According to the report, See ABORTION/ Page A8 ON THE NET Guttmacher Institute: www .guttmacher.org/ See CAREER/ Page A8 Roads scholar MondayCONVERSATION MATTHEW BECK/ChronicleBeverly Hills resident Beverly Clemo, chairwoman of the Citizens Advisory Council of the Citrus County Transportation Planning Authority, watches traffic at North Forest Ridge Boulevard near her home, where she sees a need for a bicycle path and other traffic improvements near Forest Ridge Elementary School for the benefit of its 720 students. The CAC represents residents interests in safety and maintenance issues and in planning new roads. Beverly Clemo chairs Transportation Planning Authority advisory council CHRISVANORMER Staff writerFor two years, the Citizens Advisory Council of the Citrus County Transportation Planning Authority has represented resident road-users views to the decision-makers in road planning and road maintenance. The councils chairwoman, Beverly Clemo of Beverly Hills, takes a passionate interest in how and why decisions are made, while urging residents to steer their own course by taking part as Citrus County forms a partnership with Hernando County Metropolitan Planning Organization for future transportation planning. That future includes the Suncoast Parkway 2 and the County Road 491 Medical Corridor.CHRONICLE: Why did you join the Citizens Advisory Council? CLEMO: Gary Maidhof had an article in your newspaper asking for volunteers. I got a call from my sister who was a registered professional engineer and used to be with the Department of Transportation. She knows I share an interest in transportation. She knew about my background, of course, being a former elected official. For over 25 years, I served on Regional Council of Governments in Southeastern Michigan. So, I sent him a rsum and he called me to serve. We are short one member right now from Crystal River and have been for over a year. We need somebody from Crystal River. CHRONICLE: How did you become chairwoman of the CAC? CLEMO: By default; nobody else raised their hand. CHRONICLE: When the CAC started, what were you instructed was your focus? Was it setting priorities to get funding? CLEMO: We worked with Gary Maidhof for a short time. At one of our first meetings, he asked us all what would be our priorities. Interestingly enough, the south end of County Road 491, going toward the Suncoast, was breaking up badly, striping was bad on it, and we felt that the paving See MONDAY/ Page A8 WHAT: Citrus County T ransportation Planning Authority Citizens Advisory Council meeting.

CHRISVANORMER Staff writerUpdates about Nature Coast Parkway, Floridas Future Corridors and Suncoast Parkway 2 will be presented Wednesday to the two advisory groups of the Citrus County Transportation Planning Organization (TPO). Bob Clifford, director of TBARTA (Tampa Bay Area Regional Transportation Authority) and consultant to the TPO, will present information for discussion. Nature Coast Parkway: The proposed Nature Coast Parkway is planned as a 47-mile toll facility extending the existing Turnpike Mainline near its northern terminus of I-75 northwestward to U.S. 19 north of the town of Inglis in Levy County. The facility was previously known as the Northern Extension of Floridas Turnpike. The preferred alignment is through Levy, Marion and Sumter counties. Potential Interchanges are at U.S. 19, U.S. 41, State Road 200, I-75 and State Road 44. Floridas Future Corridors Tampa Bay to Northeast Florida Study Area Concept: The Future Corridors initiative is a statewide effort led by the Florida Department of Trans porta tion (FDOT) to plan for the future of major transportation corridors critical to the states economic competitiveness and quality of life during the next 50 years. One identified study area is Tampa Bay to Northeast Florida, representing two of Floridas largest regions with large, diverse economies and growing transportation needs. Between these two regions, Gainesville and Ocala are emerging in importance as regional employment centers, par ticularly in innovation and logistics industries. Surrounding rural areas support a mix of agriculture, forestry, mining, recreation and manufacturing industries, and are collaborating on economic development strategies. This concept report identifies potential transportation strategies to help connect Tampa Bay and Northeast Florida and support the future growth of these two regions, as well as the less urbanized North Central Florida region that lies between them. Suncoast Parkway 2: The Suncoast Parkway currently extends from the Veterans Expressway in Tampa to U.S. 98 near the Hernando-Citrus county line, a distance of about 42 miles. The proposed Suncoast Parkway 2 project would extend northward about 27 miles through Hernando and Citrus counties from U.S. 98 to U.S. 19. The Florida Turnpike Enterprise is nearing completion of the 60percent design phase. As an important part of the Florida Intrastate Highway System (FIHS), the Suncoast Parkway 2 will provide a high-speed, highvolume facility on the west coast of Florida. In addition to its importance as a part of the FIHS, the Suncoast Parkway 2 project would provide needed relief to the local roadway network. As one of the fastest growing counties in the state, according to FDOT, traffic volumes in Citrus County are expected to increase dramatically in the coming decades. The Suncoast Parkway 2 project would provide additional traffic capacity to meet these future local traffic demands. Clifford will make the presentation at both meetings at 1:55p.m. for TAC members and 4p.m. for the CAC group. Both meetings are open to the public and comment from the public is heard at both the beginning and end of both meetings. Floridas Future Corridors will be the topic at the next meeting of the Citrus County Council, starting at 9a.m. Wednesday, Feb.12, at Beverly Hills Lions Club, 72 Civic Circle, Beverly Hills. Guest speakers will be FDOT representatives.

ERYN WORTHINGTON/ChronicleHarvey Jenkins, left, was proud to show Arnold Goldfoot, right, his 1957 Ford Mild Custom car Saturday at Chilsons Garages annual customer appreciation day and car show. Chilsons owner Charlie Chilson said after paying off a 25-year mortgage, he threw a party to celebrate. He enjoyed the celebration so much that he decided to continue it annually. Chilson said it is his way of thanking the community and his customers for their business for 33 years. Last year, more than 1,400 customers and friends and 130-plus cars helped Chilson celebrate. He was expecting even more this year. Abortion Coverage: The House on Jan. 28 voted, 227-188, to bar the use of federal funds to subsidize Affordable Care Act plans that cover abortion, even though the law already requires women to pay the share of the premium that applies to reproductive services. A yes vote was to send HR 7 to the Senate. Rich Nugent, Yes. Women's Medical Privacy: The House on Jan. 28 defeated, 192-221, a bid by Democrats to prevent HR 7 (above) from violating the medical privacy of any woman, including rape and incest victims, with respect to her choice or use of a healthinsurance policy. A yes vote was to adopt the motion. Nugent, No. New Farm and Food Law: The House on Jan. 29 approved, 251-166, the conference report on a five-year farm and food bill having a budget of nearly $100 billion annually. A yes vote was to pass a bill (HR 2642) that cuts food stamps by 1 percent, boosts farm exports, expands crop insurance, ends direct payments to growers, funds conservation programs and spurs rural development. Nugent, Yes. National Flood Insurance: The Senate on Jan. 30 voted, 67-32, to delay for four years steep increases in the National Flood Insurance Program's taxpayer-subsidized premiums. This would blunt reforms enacted in 2012 to trim the program's debt, which now stands at $24 billion due largely to covering damages from hurricanes Katrina and Rita in 2005 and Sandy in 2012. A yes vote was to send S 1926 to the House. Bill Nelson, Yes; Marco Rubio, Yes. Deficit Spending: Voting 64-35, the Senate on Jan. 29 reached a supermajority needed to exempt S 1926 (above) from statutory spending limits set by congressional budget resolutions. A yes vote was to advance a bill that would add $900 million over its first five years to the national debt and possibly more in later years. Nelson, Yes; Rubio, No. Flood-Insurance Premiums: The Senate on Jan. 30 defeated, 34-65, an amendment to S 1926 (above) allowing taxpayersubsidized flood-insurance premiums to rise by 25 percent annually until they reach market levels. A yes vote backed this plan in place of the bill's four-year delay of steep premium increases, starting this year. Nelson, No; Rubio, No. Key votes ahead: In the week of Feb. 3, the Senate will take up the farm-bill conference report and a bill on veterans' health benefits. The House schedule was to be announced. 2014 Thomas Reports Inc.

Its open now, we moved in last week, Rusty Skinner, chief executive officer of Workforce Connection, said. Its a nice facility, were excited about it. It offers a lot more for job-seekers, better facilities for workshops and a better flow for staff and clients. Skinner added they made a lot of improvements last year in systems, software and expanded testing and are always looking for ways to enhance their services and identify transferrable skills, especially for job-seekers who have been unemployed a while. As for the new brand, he said this is part of their attempt to become really engaged with economic development. He also sees it as an opportunity to bring more jobs into the region. We have been told the governor is excited about rebranding, he said, citing the $30 million commitment that Gov. Rick Scott announced for a workforce training initiative.

CAREERContinued from Page A1 the abortion rate dropped to 16.9 abortions per 1,000 women ages 15 to reportspercent, to 1,720, between 2008 and 2011, and the number of abortion clinics declined by just 1percentpercent of all non-hospital abortions, an increase from 17percent in 2008. Carol Tobias, president of the National Right to Life Committee, described the overall drop in abortion numbers as evidence that the anti-abortion movements lobbying and legislative efforts were having an impact. It shows that women are rejecting the idea of abortion as the answer to an unexpected pregnancy, she said. Americans United for Life, another anti-abortion group engaged in the efforts to pass restrictive state laws, said Guttmachers numbers should be viewed skeptically because they are based on voluntary selfreporting by abortion providers. It is impossible really to know the true abortion rate, said the groups president, Charmaine Yoest. The report marked the 16th time since 1973, when abortion was legalized nationwide, that Guttmacher has attempted to survey all known abortion providers in the U.S. However, a section of the new report acknowledges that some abortions might not be tallied. The highest abortion rates were in New York, Maryland, the District of Columbia, Delaware and New Jersey; the lowest were in Wyoming, Mississippi, South Dakota, Kentucky and Missouri. However, Guttmacher said many women in Wyoming and Mississippi, where providers are scarce, go out of state to get abortions.Follow David Crary on Twitter at. com/CraryAP .A8MONDAY, FEBRUARY3, 2014CITRUSCOUNTY(FL) CHRONICLENATION/LOCALh93u Doors open at 4pm Starts at 6 PM Doors open at 4pm Doors open at 4pm Starts at 6 PM Starts at 6 PM NO CASH ON PREMISES Tuesday Bingo Doors Open 4:30pm Game 6 pm Kellner Auditorium 102 Civic Circle Beverly Hills 352-746-6258 000GX0D Free Coffee & Tea Refresh men t s A v ailable VIP Drawing Mystery Game Progressive Coverall B I N G O B I N G O FREE SPECIALS NEW EXCITING Select 7 Game 776 N.

The Balfours paid off an $80,000 mortgage on the Pine Ridge home in 2008, according to county records. The house is valued on the property appraisers website at about $145,000; the couple listed it for sale in November at $225,900. Balfour said her husband, a real estate agent, began looking for property in District 4 to purchase. They settled on a 2.3-acre parcel off Cardinal Street near County Road 491. The Balfours paid $37,000 for it on May 24. The deed was recorded on June 28 ironically, Scotts letter to Balfour offering her the school board appointment was dated the same day. Balfour said she and Tom began moving their things into the mobile home the day she received official word of the appointment. Its value for the dollar, two and a half acres, fenced in. The dogs love it, she said. It was the right decision for me. Economically, the Balfours couldnt make a quick lateral move. As a veteran teacher with a masters degree, Balfour earned $54,121. To serve on the school board, Balfour had to give up her job teaching at the Academy of Environmental Sciences. A school board member makes $33,282; Balfours first-year pay is at $30,604 because she didnt take office until a few weeks after July 1, when the school districts fiscal year begins. Balfour said she plans to get her name on the ballot to run for the remaining two years of the seat in this years election. Asked why she would make such a financial and lifestyle decision to earn a spot on the school board, Balfour said: Im at a turning point in my life. I need to be in position to make a difference. Ive got a sense of value to each day and what I can contribute. Ive been told by many in the district that school board experience is necessary to make an impact.

Mile by mile, its getting done. Not as fast as we would like it, but theyre going to do another section this year, hopefully, and then weve got another section on our list. CHRONICLE: Since (former county Development Services director) Gary Maidhof unfortunately passed away, the TPO has had Bob Clifford, director of TBARTA (Tampa Bay Area Regional Transportation Authority), as its consultant. How is that working out? CLEMO: TBARTA is wonderful. I dont think our committee or the TPO could survive without TBARTA to the level we are at now and gotten the funds that are coming into the county. Their expertise has really been a savior for us. CHRONICLE: Has the funding increased because there is a TPO? CLEMO: I think its a combination of things. They are really getting their act together. Some of our projects are eligible for federal funds. North Florida Avenue, for example, has been on the wish list for quite a while. That is a project that is eligible for federal funds. CHRONICLE: What happens when your committee wants something? CLEMO: It came to our attention that there was a problem on Lecanto (Highway) with people driving around the school buses. When the school buses were stopping, people werent stopping. We asked TBARTA to bring them in. They brought the sheriff in and the school district in and we talked about what the problem was. One serious area was at the nursery school just south of Gulf-to-Lake on the west side of the street (C.R. 491). Parents were driving in there and school buses and there was traffic on the other side of the road. The short-term solution that the county did was to put the dividers up in the center. But its not just us requesting it. Letters go out. CHRONICLE: Do you have any concern about joining with Hernando MPO? CLEMO: One concern I do have with the MPO merger with Hernando is people might not want to drive there. CHRONICLE: How successful are you in getting people to come to your meetings? CLEMO: We meet at 3 p.m. the first Wednesday of the month and we are there until 5p.m. at least, which is just a terrible time for a lot of people to come. No, we dont get a lot of people coming. CHRONICLE: How can people contact you? CLEMO: We are not currently listed on the county website. I think its something thats fallen through the cracks. Hernando MPO will have staff, so hopefully there will be a number that people can call. Now people end up calling TBARTA, which is good.

MONDAYContinued from Page A1 Paul Ryan: Immigration legislation unlikely in Associated PressWASHINGTON Days after House Republicans unveiled a roadmap for an overhaul of the nations broken immigration system, one of its backers said legislation is unlikely to pass during this election year. Rep. Paul Ryan, R-Wis., said distrust of President Barack Obama runs so deep in the Republican caucus that hes skeptical the GOP-led House would pass any immigration measure. He said a plan that puts security first could only pass if lawmakers believe the administration would enforce it an unlikely prospect given Republicans deep opposition to Obama. This isnt a trust-butverify, this is a verify-thentrust approach, Ryan said. Last week, House Republicans announced their broad concerns for any immigration overhaul but emphasized they would tackle the challenge bill-by-bill. Immigration legislation is a dicey political question for the GOP. The partys conservative base opposes any measure that would create a pathway to citizenship for immigrants living here illegally, but many in the party worry that failing to act could drive many voters to Democratic candidates. In 2012, Obama won reelection with the backing of 71 percent of Hispanic voters and 73 percent of Asian voters. The issue is important to both blocs. Republicans have preemptively been trying to blame the White House for immigration legislations failure, even before a House bill comes together. House Majority Leader Eric Cantor said the dont think government will enforce the law anyway, Rubio said, recounting conversations hes dont want to have a permanent separation of classes or two permanent different classes of Americans in this country. Last week, Obama suggested that hes open to a legal status for immigration that falls short of citizenship, hinting he could find common ground with House Republicans. Im going to do everything I can in the coming months to see if we can get this over the finish line, Obama said Friday.

Betz MorristonInterest of fairnessThis is in response to your Jan. 16 Chronicleeditorial, Lets have adult conversations about the issues, that accused myself, a candidate for Citrus County Commissioner, District 2, of being involved in a silly season squabble for my stance and complaint to the chairman of the Republican Executive Committee for a fair Republican primary without an elected official expressing bias and attempting to affect the election prior to the primary election that is against Republican Party policy. The unfair bias before the election primary, without even going into unfair bias against myself is evident even by theChroniclearticle of Jan. 6, Candidate, commissioner exchange terse emails, in which Commissioner (Scott) Adams said he would not be supporting incumbents. Even though I am not an incumbent at this point, this type of public statement alone by any elected official should be avoided for a non-biased election. Furthermore, my intention has been for fairness for this election so the voters will not be blinded by the political power plays of any elected official to ensure that according to the title of your editorial, we can have adult conversations about the issues. Fairness is mature and not silly.Renee Christopher-McPheeters Homosassa Doug Varrieur likes to shoot. Problem is, its 25 miles to the nearest range, where they charge $45 an hour. Whats a gun enthusiast to do? Lucky for him, Varrieur lives in Florida. Problem solved. Just erect a makeshift range in the back yard and fire away. Its perfectly legal. Re-read that if you want. Its just as nutty the second time around. In a story by my colleague Cammy Clark that appeared in Sundays Miami Herald, we learn that Varrieur, who lives on Big Pine Key, once complained to a gunshop owner about what a pain it was going to the range to shoot. The owner put him onto Florida statute 790.15, which lists the conditions under which one may not legally discharge a firearm in the state. Turns out there arent many. You may not shoot in any public place or on the right-of-way of any paved public road, highway or street, over any road, highway or occupied premises, or recklessly or negligently at your own home. Otherwise, let er rip. There are no mandatory safety requirements. Indeed, the language about recklessness and negligence doesnt take the precautions the law says he doesnt have to bother with? For what itsre trying to make it legal to take one to church. So this isnt just Florida. Its America. We live in states of insanity. As it happens, I have been corresponding with a reader who wrote me with what I regarded as promising ideas for moving the gun-rights argument forward. They included mandatory gun-safety training and mandatory liability insurance. The dialogue faltered on his contention that he needs his gun because crime is spiraling out of control, and the country is not as safe as it was 20 years ago. This, of course, is false: crime is at historic lows. In 1993, according to the FBI, the violentcrime rate was 747.1 per 100,000 people. In 2012, the most recent year for which figures are available, it was 386.9. Almost 10,000 fewer people were murdered in 2012 than in 1993. My reader was impressed with none of this. Forget stats, he said, talk to victims. If I did, Id learn that road rage and knockout incidents are way up and that nightly, there are home invasions, robberies, stabbings and, ahem, shootings. His insistence on perception over fact is emblematic of the nation weve become, so terrified by local TV news and its overreportage of street crime that we think every shadow has eyes and we need guns in school, the bar, the movies, church. Until some of us get over this media-driven paranoia, even promising ideas for ending the guns impasse are doomed. So I will close with some words of advice to anyone thinking of visiting or living in Florida or any other state of American insanity. One word, actually: Duck.Leonard Pitts is a columnist for The Miami Herald, 1 Herald Plaza, Miami, FL 33132. Readers may contact him via email at lpitts@ miamiherald.com. The trouble with the profit system has always been that it was highly unprofitable to most people.E.B. White, 1944 Trigger happy in the gunshine ACCRUAL BUSINESS In banks farewell, a story bigger than Citrus Theres one less bank in Citrus County. CenterState Bank, one of the 20 banks doing business in the county, will close its Crystal River and Inverness locations in April. David Donato, CenterStates community president for Citrus and Hernando counties, characterized the retrenchment by saying Some markets are more depressed than others. Were not sure thats entirely true: Citrus may not be booming, but there are plenty of banks thriving within the county. Saturation, and not depression, is the more likely culprit. The closings coincided with internal restructuring the bank hopes will cut costs and make it a more attractive lender to larger spenders. Indeed, as it gets smaller, CenterState is doing its best to get bigger. The banks two Citrus branches were among eight shuttered across the state, and yet Thursday the bank announced its acquisition of First Southern Bancorp Inc., which has 17 branches scattered throughout central, northeast and southeast Florida. Rather than being a sign of Citrus Countys continuing economic decline, the broader story in CenterStates departure is the story of our time: a small player trying to find its footing in a rapidly shifting market dominated by multinational corporations amid a sea change in the way business is done. The banking sector looked much different when CenterState emerged in the early s, and its competition has only consolidated, leaving it up against global conglomerates that are too big to fail and have, it must seem, unlimited resources to devote to courting customers. The loss of the banks presence in Citrus County is unfortunate, and should serve as a reminder that economic development needs to be at the forefront of the community conversation. Nevertheless, were confident that CenterStates Citrus customers will be well served by whichever competitor is fortunate enough to earn their business. THE ISSUE:CenterState Bank pulls out of Citrus County.OUR OPINION:A casualty, but not a catastrophe. Build for animals and homelessI see no reason why Citrus County cannot build a new home for the animals, a new shelter, and build a home for the homeless. Theres no reason why we cant do both. We have a lot of retirees with good skills that would help do this.Whats new about that?I just saw on TV where Florida is one of the first states in the United States that is going to allow driverless cars that is, the new computer-driven cars where the computer drives the car. So Florida is going to be one of the first for driverless cars. Im like, what else is new? Tell me the weather!Can somebody please tell me what the temperature is in Homosassa Springs, Homosassa Springs, Fla.? We have gotten a new channel for the weather and it stinks. Its every place else except where we were. Give us back our channel. Youve taken away a lot of things. Weve got Puerto Rican channels now, Mexican channels. What are you doing to our television? We shouldnt even have television anymore. Television st Leonard PittsOTHER VOICES They should all sufferToday is Friday, Jan. 17, and Im reading in the Chronicle about a lawyer who was upset because a killer illegally suffered during his execution. Well, who speaks for the victim? Who speaks for the victims family, how they have suffered all these years? I really dont care if he suffered or not. In fact, I hope they all suffer when they get executed. They deserve it.Eye for an eyeI read a small article that a lawyer in Ohio said that a condemned killer that he represented suffered during his execution. Gee, I wonder if anybody worried about the person that this killer murdered. Did that person suffer? An eye for an eye, a tooth for a tooth. If he suffered, tough. He got what he deserved.Good newsA condemned killer in Ohio suffered during his execution, according to witnesses and I was certainly glad to hear that. CITRUSCOUNTYCHRONICLE Hot Corner: EXECUTION

After delay, season begins at Citrus County Speedway SEANARNOLD CorrespondentINVERNESS After Fridays rain pushed back the Citrus County Speedways grand reopening by a day, the wait for a new season came to an end with six feature races on Saturday. While out-of-county drivers claimed each of the main events, it was Aaron Pierce, of Indianapolis, Ind., who traveled the farthest of the bunch and beat out the largest field of the night, in prevailing over 23 non-winged sprint cars in 30 laps. Aaron Williamson (Sportsman), Clint Foley (Modified Mini Stocks) and Raymond Vann (Pro Hornets) each scored wire-to-wire feature wins after taking their respective heats. Pierce started the race in the middle of the pack and climbed to the fourth position behind Tampas Joey Agvilar and Mickey Kempgens and leader Jimmy Alvis Sr., of Seffner by lap six. Kempgens and Pierce made it past Agvilar on 13, before the pair touched on 16, putting Kempgens in a spin coming out of the fourth turn. Pierce wasnt penalized, but later apologized, saying he was unintentionally at fault. Pierce grabbed the lead from Alvis, who finished second, moments before a caution on 25, and held on from there. Agvilar finished third. (Kempgens and I) are friends, said Pierce, who expects to return to Citrus, and hes driven my car before at the Little 500 (in Indiana). I locked both front wheels trying to keep from hitting him. I barely got him, but it was while he was cutting across. In Mini Stocks, Summerfields Shannon Kennedy (No. 20) chased down Lutzs Tim Scalise midway through the nights opening feature. Scalise, the heat winner, went on to finish second, between feature winner Kennedy and third places Jerry Daniels of Weirsdale. Websters Mark Patterson was in third place on lap 19 when an engine rod broke on his No. 22. Lakelands Becca Monopoli cruised to a win over a five-car field in the 35-lap Pro Trucks feature after she pushed her way to the front with a strong move on the second lap. Monopoli, who started in third and briefly went three-wide in the early moments, reestablished her lead over Jupiters Dustin Dunn (second-place finish) and Lakelands Dylan Martin (third) on lap three, following the only yellow flag of the race. Foley didnt appear to have much trouble defeating seven other cars in the Mod Minis feature, but he did lose his exhaust pipe, causing exhaust fumes to leave some burns under the Dunnellon drivers right arm during the race. It got really hot in there, he said. Floral Citys Kevin Harrod ran second the entire 25-lap race, and Clermonts Michael Lawhorn moved up a row from his starting position to get third place. Like Foley and Monopoli, Williamsons feature win brought little drama, though his last-minute decision to race at Citrus meant he and his No. 13 arrived moments before the checkin deadline. The Lakeland driver extended his pole-position lead over the first 14 laps, and regained his advantage after a couple of cautions in the second half of the five-car, 25-lap event. Fellow Lakeland driver Charlie Brown took second place, and Beverly Hills Jay Witfoth, in placing third, was the only Citrus County driver to score a top three finish on the night. Super Late Models headline next Saturdays racing action with a seasonopening 50-lap event, while Mod Minis, Street Stocks, Pure Stocks, Mini Stocks, Pure and Street Stocks Figure 8s and a fan participation race round out the schedule.

Stadlers previous biggest win was in Australia in the European Toursaps No. 1 offense and defense, the D dominated. Its all about making history, All-Pro safety Earl Thomas said. This was a dominant performance from top to bottom. Denver fell to 2-5 in Super Bowls, and by the end many of Mannings didnt Chicagos Devin Hesters kickoff return to open the 2007 game against Manningsnings third-down pass to Julius Thomas sailed way too high and directly to safety Kam Chancellor, giving the Seahawks the ball at Denversnings arm as he was throwing, the ball fluttered directly to Smith, who took off down the left sideline for a 69-yard interception TD. Manning trudged to the sideline, a look of disgust on his face. That look didnt improve when, after a drive to the Seattle 19, his fourth-down pass was tipped by Chris Clemons and fell harmlessly to the Meadowlands turf.

Multimethods
Methods are the workhorses of Magpie. Most of the code you write will reside inside a method, and most of that code will in turn be calls to other methods. A method is an executable chunk of code (an expression to be precise) that is bound to a name and has a pattern that describes the argument it expects.
Defining Methods
Methods are defined using the
def keyword.
def greet() print("Hi!") end
Here we've defined a method named
greet whose body is a block containing a single
greet()
We can define a method that takes an argument by using a pattern in its definition.
def greet(who) print("Hi, " + who) end greet("Fred") // Hi, Fred
In this case, the pattern
who is a simple variable pattern, but more complex patterns can be used:
def greet(who is String, whoElse is String) print("Hi, " + who + " and " + whoElse) end greet("Fred", "George")
Here we have a record pattern with two fields that must both be strings. We call it by passing it a record of two strings:
"Fred", "George". This may seem a bit strange, but it's important to note that we are not passing two arguments. In Magpie, methods (and functions) always take a single argument. It's just that the argument may be a record which the method destructures.
The end result is that it works pretty much like other languages, but there's some conceptual unification going on under the hood. The destructuring initialization that you can do when declaring variables is the exact same process used when splitting out arguments to a method, or selecting a
catch clause when an error is thrown.
Left and Right Arguments
Method calls are infix expressions, which means that an argument may appear to the left of the name, to the right, or both. (More pedantically, the record that forms the single argument may have fields which appear to the left and right of the name.)
The
greet methods we've defined so far only have a right argument. Methods which only have a left argument are informally called getters.
def (this is String) isEmpty this count == 0 end
This defines a getter
isEmpty whose left argument must be a string. It takes no right argument. It can be called like this:
"not empty" isEmpty // false
And, finally, methods can have arguments on both sides:
def (this is String) greet(other is String) print("Hi, " + other + ", I'm " + this) end "Fred" greet("George")
When you define a method, the argument patterns always need to be in parentheses. When you call a method, only the right one must. If you chain several method calls, they associate to the left (like most languages). For example, this:
people find("Smith") firstName greet("George")
is the same as:
((people find("Fred")) firstName) greet("George")
Setters
In addition to getters, you can also define setter methods. Like getters, setters are just regular methods, but they have special syntax to make them look like assignment. You define a setter like so:
def (this is Person) name = (name is String) print("Set name to " + name + "...") end
The
= followed by a pattern tells Magpie that you're defining a setter. We can call the above setter:
person name = "Fred"
A setter may also have a right argument:
def (this is Contact) phoneNumber(type is String) = (number is String) print("Set " + type + " number to " + number) end jenny phoneNumber("Home") = "867-5309"
Magpie tries to roll as much behavior under method calls as possible and getters and setters are a good example of that. It's worth noting that everything that looks like a getter or setter is just a method call. When you're accessing fields in a class, you're just calling getter and setter methods that have automatically created implementations.
Indexers
In addition to setters, Magpie has one more little bit of extra syntax for method calls. To make working with collection-like objects easier, it provides indexer methods. These are essentially methods whose name is
[]. The left argument appears before the brackets, and the right argument is inside them.
list[2]
Here, we're accessing an element from some
list variable by calling an indexer method. The left argument is
list and the right argument is
2. Aside from their syntax, there is nothing special about indexers. They're just methods like any other and you're free to define your own indexers, like so:
def (this is String)[index is Int] this substring(index, 1) end
Here, we've defined an indexer on strings that takes a number and returns the character at that index (as a string). As you'd expect, the right argument can also be a record:
defclass Grid val width is Int val height is Int val cells is List end def (this is Grid)[x is Int, y is Int] cells[y * width + x] end
Here we've defined a
Grid class that represents a 2D array of cells. It includes an indexer for getting the cell at a given coordinate. You can call it like this:
val cell = grid[2, 3]
You can also define indexer setters which combines the syntax of those:
def (this is Grid)[x is Int, y is Int] = (value) cells[y * with + x] = value end grid[2, 3] = "some value"
Method Scope
Magpie's method call syntax looks similar to other OOP languages where a "receiver" argument precedes the method. We've seen some examples where we define methods whose left argument is a built-in type like
String. In other languages, this is called monkey-patching and doing it is fraught with peril. The reason is that when you invoke a method in those languages, it looks up the method on the class of the receiver. If two unrelated parts of the program define a method with the same name on the same class, those two methods will collide. When we call it later we may find the wrong one.
In Magpie (as in CLOS) methods are not owned by classes. Instead, methods reside in lexical scope, just like variables. When you call a method, the method is found by looking for it in the scope where the call appears, and not on the class of any of the arguments. When a method goes out of scope, it disappears just like a variable.
do def (this is String) method() print(this + " first") end "a" method() // a first end a method() // ERROR! do def (this is String) method() print(this + " second") end "a" method() // a second end
It is impossible to have a method collision in Magpie. If you try to define two methods with the same name and pattern in the same scope, it will throw an error. This way, you can define methods that have a nice readable calling syntax without having to worry about breaking code in some other part of the codebase.
Checking for pattern collisions hasn't been implemented yet.
Multimethods
In Magpie, all methods are multimethods. This is one of the places where the language really steps it up compared to other dynamic languages. In the previous section, we noted that it's an error to define two methods with the same name and pattern in the same scope. That qualifier is important. It's perfectly fine to define two methods with the same name but different patterns.
def double(n is Int) n * 2 end def double(s is String) s + s end
Here we've defined two
double methods, one on strings and one and numbers. Even though they are defined in the same scope, these don't collide with each other. Instead, these are combined to form a single
double multimethod containing two specializations.
When you call a multimethod, it looks through the methods it contains and their patterns. It then selects the most appropriate pattern, and calls the method associated with it.
double(3) // 6 double("ma") // mama
In simple terms, this means Magpie lets you overload methods, which is pretty unusual in dynamic languages. It's also more powerful than most static languages because it's selecting the most appropriate method at runtime where overloading in a language like Java is done at compile time.
Since all methods actually take a single argument, we're free to specialize a multimethod on the left argument, right argument, or both. You can also specialize on different record patterns.
def (this is String) double this + this end def (this is Int) double this * 2 end def double(s is String, s is Int) s + s, n * 2 end "left" double // leftleft 3 double // 6 double(3, "do") // 6, dodo
As long as you don't provide two specializations with the exact same pattern, you are free to define as many as you want. If you call a multimethod with an argument that doesn't match any of the specializations, it will throw an error.
do double(true) catch is NoMethodError print("We didn't specialize double on bools") end
We didn't define a
double method that accepts a boolean, so when we call it, it will throw a
NoMethodError which gets caught here to print a warning.
Linearization
TODO(bob): Methods are partial order now, not a strict linearization. Need to update this.
The previous section says that the "most appropriate" method is selected based on the argument. In the examples we've seen so far, only one method is a possible match, so most appropriate is pretty easy. If multiple methods match the argument, we need to determine the best one. Magpie (and other languages) call this linearization.
def odd?(0) false end def odd?(n is Int) not(odd?(n - 1)) end
Here we have an
odd? multimethod with two specializations. If we call it and pass in
0, then both specializations match. Which is best? To answer this, Magpie has a few relatively simple rules that it uses to order the patterns.
Before we get to those rules, it's important to understand one thing that does not affect ordering: the order that methods are defined in a program has no effect on linearization.
Pattern Kind
First, different kinds of patterns are ordered. From best to worst:
- Value patterns
- Record patterns
- Type patterns
- Wildcard patterns
For variable patterns, we look at its inner pattern. (If it doesn't have one, it is implicitly
_, the wildcard pattern.) The above list addresses our
odd? example: the first method will win since a value pattern (
0) takes precedence over a type pattern (
is Int).
To linearize two patterns of the same kind, we need more precise rules.
Class Ordering
To order two type patterns, we look at the classes being compared and see how they are related to each other. Subclasses take precedence over superclasses.
defclass Parent end defclass Child is Parent end def sayClass(is Parent) print("Parent") end def sayClass(is Child) print("Child") end sayClass(Child new())
Here, both methods match because an instance of
Child is also an instance of
Parent. In this case, the second method specialized to
is Child wins because
Child is a subclass of
Parent.
Record Ordering
It's possible for two record patterns to match the same argument.
def printPoint(x: x, y: y) print(x + ", " + y) end def printPoint(x: x, y: y, z: z) print(x + ", " + y + ", " + z) end printPoint(x: 1, y: 2, z: 3)
A record pattern matches as long as the argument has the fields the record requires. Extra fields are allowed and ignored, so here both methods match. It's also possible for records with the same fields but different field patterns to match:
def sameGeneration?(a: is Parent, b: is Parent) true end def sameGeneration?(a: is Child, b: is Child) true end def sameGeneration?(a: _, b: _) false end
Ordering these can be complex, so the linearization rules for records a bit subtle. The first requirement is that the records must specify the same fields, or one must be a subset of the other. If not, they cannot be ordered and an
AmbiguousMethodError is thrown.
def say(x: x) print("x " + x) end def say(y: y) print("y " + y) end say(x: 1, y: 2)
It's unclear what the programmer was even trying to accomplish here, and Magpie can't read your mind. So in cases like this, it just raises an error to signal its confusion. Our first example doesn't have this problem, though. The first definition of
printPoint is a subset of the former, so there's no ambiguity. In that case, it proceeds to the next step.
There are several signals we can rely on to tell us which record should come first. We'll call those lean. To order records in a predictable way, those signals need to agree with each other. The first signal is if one record has fields the other doesn't. In our first
printPoint example, the second method has an extra
z: field. That means we lean towards preferring that method since it "uses more" of the argument that gets passed in.
Next, we go through the fields that the two records have in common and linearize their patterns. Whichever pattern wins is a lean towards that record. (If the patterns compare the same, like the
x and
y fields in the two
printPoint methods, then there's no lean one way or the other.)
If all of the leans are towards one record, it wins. If the leans are inconsistent then it's ambiguous. This is all a bit fishy, so some examples should clarify:
x: x, y: y x: x, y: y, z: z // Second wins: more fields x: x, y: y y: y, z: z // Ambiguous: neither is a subset of the other a: is Parent, b: is Parent a: is Child, b: is Parent // Second wins: Child is more specific a: is Parent, b: is Child a: is Child, b: is Parent // Ambiguous: fields disagree
The general theme here is that it tries to pick records that are "obviously" the more specific one where "more specific" means more fields or more precise fields. If it isn't crystal clear which one the programmer intended to win, Magpie just throws its hands up and pleads confusion. | http://magpie.stuffwithstuff.com/multimethods.html | CC-MAIN-2014-15 | refinedweb | 2,387 | 69.41 |
Before being able to work on this problem, you should know what we are talking about. In a few words, a BST is a tree in which for each node is true that its left children are strictly smaller and the right one are strictly bigger.
In Python, if a node is represented in this way
class Node: def __init__(self, data): self.data = data self.left = None self.right = NoneWe can check a tree passing its root to a recursive function like this one:
def is_bst(node, left, right): # 1 if node is None: # 2 return True if not left < node.data < right: # 3 return False return is_bst(node.left, left, node.data) and is_bst(node.right, node.data, right) # 41. The first parameter, node, is an instance of the class Node. The other two parameters are the limit in which the value is supposed to be. 2. An empty tree is a BST. This comes handy to manage the leaves of the tree. 3. The node value should lie in the specified interval, otherwise this is not a BST. 4. If the current node passes the check, we explore the rest of the tree. On the left we restrict the interval cutting it to the right, on the right we cut it on the left. Couple of questions. What should we pass as left and right for the root? And, What if we don't want to accept an empty tree as a valid BST? I think that in Python a good solution could be having a starting call like is_bst(root) that do not check for an interval and define on its own what to do in case of None. And then it call the above is_bst() for all the other nodes. | http://thisthread.blogspot.com/2017/02/hackerrank-trees-is-this-binary-search.html | CC-MAIN-2018-43 | refinedweb | 295 | 83.86 |
Summary: Learn about using Windows PowerShell and specifying different calendar types to use with dates.
Microsoft Scripting Guy, Ed Wilson, is here. Today is day four of my PowerShell Essentials for the Busy Admin series of webcasts. The series has been a lot of fun, and the feedback so far has been great. It is encouraging to see the level of interest in this series. In addition, there have been a decent amount of questions via the scripter@microsoft.com email alias about the series of live meetings in addition to the 2012 Scripting Games.
Today is the Ides of March. For the Scripting Wife, it means March Madness is underway. For me, I think back to the play by William Shakespeare, Julius Caesar. Beware the Ides of March…
If you want to work with calendars in Windows PowerShell, perhaps you should also beware of the Ides of March—or at least be aware of how to work with different calendar types.
Anyway, the .NET Framework classes are fun to play with. If I want to create a specific date, I can use the constructor for the System.DateTime .NET Framework class and create a date. To do this, I use the New-Object cmdlet to specify the name of the .NET Framework class I want to use, and I pass the arguments for the constructor to the ArgumenLlist parameter.
With the System.DateTime .NET Framework class, there are several different constructors. As a matter of a fact, MSDN lists 11 different constructors on the System.DateTime details page. To create a new DateTime object and specify the year, month, and day, requires me to use a particular constructor. Using Windows PowerShell to create a new instance of the System.DateTime class by passing the year, month, and day is shown here.
PS C:\> New-Object system.datetime -ArgumentList 2012,3,15
Thursday, March 15, 2012 12:00:00 AM
Of course, I can do the same thing by using the Get-Date cmdlet. I am not certain it is any easier, but it is a bit less typing. It is definitely easier to read the Get-Date command. This command and the output associated with the command are shown here.
PS C:\> Get-Date -Month 3 -Day 15 -Year 2012
Thursday, March 15, 2012 5:29:42 PM
The easiest way to create a specific date is to cast a string to the DateTime object. This technique is shown here.
PS C:\> [datetime]"3/15/12"
Thursday, March 15, 2012 12:00:00 AM
All three of the previous examples, however, use the same calendar—the Gregorian calendar. A problem arises if I need to specify a particular calendar. To do this, I need to first create an instance of the specific calendar I want to use. Next, I use the constructor for the System.DateTime class that permits supplying the specific calendar. Because today is the Ides of March, it makes sense to use the Julian calendar as an example. Julius Caesar ordered a calendar reform that resulted in the creation of the Julian calendar. The Julian calendar is the predecessor of the Gregorian calendar.
Luckily, the .NET Framework makes these types of conversions from calendar to calendar really easy. I only need to create a new instance of the JulianCalendar class to be able to use it in the constructor to create a Julian calendar type of date. Once again, I use the New-Object cmdlet to create an instance of the class. But I do not need to pass any arguments to the JulianCalendar class. Therefore, no ArgumentList parameter is needed.
In the code that follows, I use the New-Object cmdlet to create a new instance of the JulianCalendar class, and I store the resulting calendar in the $j variable. I then use this calendar in the New-Object command that creates a specific date. The result is a specific date, reflected in a specific calendar. These two lines of code are shown here.
$j = new-object system.globalization.julianCalendar
New-Object system.datetime -ArgumentList 2012,3,15,$j
There are lots of different types of calendars defined in the .NET Framework. All of the calendars reside in the System.Globalization .NET framework namespace. To get a feel for the different calendars, spend a bit of time on MSDN and review the various calendar classes.
In the image that follows, I first create a DateTime object that represents March 15, 2012, and I display that DateTime object to the Windows PowerShell console. I then create an instance of the JulianCalendar class, and store that calendar in the $j variable. I next use the New-Object cmdlet and create the date March 15, 2012 by using the Julian calendar. These commands and the associated output are shown in the image that follows.
If you want to know what a specific calendar does, you can create the calendar object, store it in a variable, and then display the contents of that variable. Information returned by doing this includes the minimum supported date and the maximum supported date. In the image that follows, I list information for both the Julian calendar and the Gregorian calendar.
Anyway, beware the Ides of March—especially if you are not sure what calendar is being quick comment on international dates.
Regarding
[datetime]"3/15/12"
The syntax shows month/day/year and results in
Thursday, March 15, 2012 12:00:00 AM
Living in the UK I'm more used to day/month/year but if I try
PS> [datetime]"51/3/12"
Cannot convert value "51/3/12" to type "System.DateTime". Error: "String was not recognized as a valid DateTime."
I have to do
[datetime]"3/15/12"
Over the years I have found that its safer for me to do
[datetime]"15 March 2012"
as it always works.
This is caused by the culture settings in PowerShell
PS> Get-Culture
LCID Name DisplayName

@Richard.Siddaway
Having saved me the need to note the locale dependency in the article's example, there is a solution: Use ISO format. This is unambiguous with a four digit year:
PS> [datetime]"2012-08-10"
will always give you midnight 10 August 2010.
Hi Ed,
a good short article that explains some details of dates.
It is quite ingteresting what we can do with dates and we should pay attention to date formats!
@Richard: Right! Living in Germany, I encounter the same problems, you do!
But there is one thing, I can asure you … you typed in: [datetime]"51/3/12"
This will never be a valid date … not in the UK, not in the US and not here :-)))

<scribe> scribenick: krit
ed: first topic time
changes
... australia with the latest change?
... 3 weeks time all transit. Then we review chnages to times
cyril: I think we should switch to morning in europe
Tav: doesn't work for the damn americans
<ChrisL> lol
cyril: doesn't work for east coste
cabanier: what about west coast
cyril: haha
Tav: 1h later in europe one hour later in australia last year
<ed> shows 20.00 UTC May 1, 2012
krit: cabanier: 1 hour later is fine for us
<ed> so, sydney 6am... maybe not great
cabanier: 1 earlier is not that good for australia
cyril: we should check with cameron
krit: stay for now?
ed: stay till 3 weeks when all countries switched
cyril: 2 more weeks
ed: keep the time for 2 more weeks
… more discussions about time shift
ed: no decision now?
all: lets stay for the next 2 weeks
resolution: keep the time for 2 weeks
<scribe> ACTION: erik will send a mail for time shift and time change [recorded in]
<trackbot> Created ACTION-3245 - Will send a mail for time shift and time change [on Erik Dahlström - due 2012-03-15].
next topic: template for tests
ChrisL: mails on mailing list
<ed>
Tav: cameron said that html tag inside svg and try to add html inside svg you'' break
ChrisL: cameron suggested a lot
more chnages
... he seems to wnat to have a whole new layer
Tav: link and meta are not part of svg
ChrisL: we had a resolution to
add them
... anyway we should ask peter
... wecould add it to our svg naemspace
ed: html5's parsing algorithm would break out into html mode if we didn't parent the link and meta elements inside a foreignobject
ChrisL: it seems to be a clear resolution that al changes might break html5 parsing. for those test we need something different
Tav: cameron suggestions is a bit simplper
ChrisL: i didn't like it
<ChrisL> I think he has oversimplified and it will loose functionality
Tav: he is not removing
anything
... he just implementes in another way
... he is just not put html5 into ahead
??
Tav: th eproblem with meta
tag.
... he still has a data tag
Tach if an html5 parser finds a link in a svg tag
ChrisL: what happens?
Tav: I don't know
ChrisL: html parser don't care
about the tags at all
... a framwork in place to start writing tests
... otherwise they don't get it wrten
ed: I prefer simplified
structure
... no namespaces
Tav: I agree
ChrisL: we had the test criteria … where did it went?
Tav: the test harness has to be modified to do that
ChrisL: is that in the head and a
meta
... simplicity is goood
but
Tav: link to the different parts
of the spec
... and which parts it needs to pass
<Tav>
Tav: test assertions:
ChrisL: it is all in the content
attribute
... no markup at all
Tav: above in the spec links, there is a link that tells you what part of the spec gets tested
ChrisL: thats fine
<cyril> seems broken
<ed> the tags that break out of "foreign" mode (aka SVG in html): (link is not among those)
ChrisL: ok
ed: meta does break out
Tav: link is ok
ed: yes
Tav: you still need sth for the
... description is ok
ed: could we use svg metadata element?
ed: just sth to put test meta
data on
... should be fine
ChrisL: would be fine than
... peter should know what we want to do
ed: metadata should replace meta
eleemnt
... link lists all the tags that break out
... link element would get unknown svg element
... needs verification
ChrisL: so no other namespace, no
head
... just metadata?
<ed>
ed: I dont see a circle in opera and safari
<ChrisL> <!DOCTYPE html>
<ChrisL> <svg>
<ChrisL> <link/>
<ChrisL> <circle r=200>
ChrisL: I see the circle in FF with this example
Tav: I don't
<ChrisL> ff11beta6
ed: I don't see a circle either
Tav: now I see
... I put a space before the slash
<ed>
cyril: we should move on
ChrisL: we should have a decision
ed: link is fine
resolution: we will use the link element as proposed. Use metadata instead of head and meta
<ed> example: instead of <meta name="flags" content="TOKENS" /> we will use <metadata name="flags" content="TOKENS" />
Tav: what cameron sugeested with metadat
a
Tav: basically
<Tav>
ed: something else on his proposal
Tav: yes, the very last
thing
... that we diagree too
... other issues with copy right… a list that ChrisL sent
ed: Tav'll send a final proposal to the list
<ChrisL>
ed: peter should review
ChrisL: ed can you edit the wiki?
ed: ok
<ChrisL> s/ ed can you edit the wiki?/I am editing the wiki
ChrisL: metadata for flags
?
<ed> <metadata name="flags" content="TOKENS" />
Tav: the desc tag for the text description
ed: should it be long or short descr?
Tav: as long as you need/
ChrisL: if we agree, than we ask peter
Tav: ok
... what about copyright
ed: use BSD for the suite
ChrisL: put the license into one place and link to it
Tav: I agree
<scribe> ACTION: ChrisL will edit the wiki page and mention how to add license and copyright [recorded in]
<trackbot> Created ACTION-3246 - Will edit the wiki page and mention how to add license and copyright [on Chris Lilley - due 2012-03-15].
Tav: what about revision?
... we have version controll system, so no extra revisions
ChrisL: we don't put the number
in the file
... not productive to do that
... the same for the test frame
ed: agree
Tav: I tried to add the testing to the rep, but it failed
ed: ChrisLdo you edit the wiki and mention what we do about revision?
ChrisL: I will
… discussion about problems for Tav to submit stuff
ed: back to the requirements
<ed>
ed: resolve accept the structure of tests
<ed> agreed to the section: Structure after 8 March 2012 telcon
ed: anyone against this template?
silence
resolution: Accept the testing template
<cyril>
ChrisL: we should drop xlink on <a>
ed: xlink:role, xlink:arcrole and xlink:title:title might make sense
ChrisL: title element is better
than xlink:title
... we should use title element
ed: no strong objections
... fine for ,e
resolution: drop xlink attributes role, arcole, title
<ChrisL> resolution: SVG2 will drop xlink attributes role, arcole, title
resolution: SVG 2 will drop the xlink attributes role, arcole, title
<ed>
ChrisL: improve text is fine
<cyril>
ed: we should keep it, but remove xlink:title from the spec
resolution: SVG 2 will include Improved text for the indicating links
<ChrisL> resolution: svg2 will port the text from svgt1.2
ed: next one
<scribe> new scripting featuress
ed: svg tiny is more simple
... on media fragment
... they are not incompatible
<ChrisL> resolution: svg2 will merge the svg1.1se text and the svgt12 text on fragment identifiers link traversal
<ChrisL> oh and add media fragments
ChrisL: what about media fragments?
ed: we should look at it
... is part of the same feature
... more the same thing
... rephrase resolution?
<ChrisL> ACTION: chrisl to merge the svg1.1se and svgt1.2 fragment identifier text and consider adding in media fragments for partial images [recorded in]

ed: procsessing inline scripts
<ed>
cyril: i expected that there were differences between svg 1.1 and 1.2 tiny
ChrisL: html5 has similar
things
... we should compatible to html5
ed: reasonable
ChrisL: we should look at it in
detail first
... needs an action
cyril: we already have a resolution for async,. sooo
ed: the section on tiny is very
short
... you have to look at the type attribute and so on
... there is nothing similar in SVG 1.1
resolution: SVG 2 will define how inline scriptable content will be processed, in compatible way to HTML5
<ed>
ed: new scriptiing features
... we should port it over 'script element text'
resolution: SVG 2 will merge SVG1.1SE and SVG 1.2 Tiny on script element text
ed: next one change erik to SVG WG and copy paste resolution on wiki page
<ed>
<cyril> RESOLUTION: SVG 2 will use the relevant parts from 1.2T and align with the html script element.
ed: next is animation
<ed>
<ChrisL> erik: svgt1.2 defines what happens when there are errors in a begin-value-list
ed: tiny is more specific what to do on attribute for wrong content
resolution: SVG 2 will apply
changes of SVG 1.2 tiny on animation module
... SVG 2 will apply changes from SVG 1.2 tiny to the SVG animation section
ed: fonts are no modification in tiny
<ed>
ed extenisibility we have the xlink:href attribute on foreignObject
krit: do we have the same rules like for iframe if we support xlink:href?
ed: customers want to use it for
some magic things, but basically as a plugin frame
... it would be fine to have it. resolution?
krit: so. should get an action to check security problems
cabanier: most rules of iframe have to apply here as well
resolution: SVG 2 will support xlink:href on foreignObject element after security verification

I've written most recently a slew of posts around Bing's work with startups at Bing Booster - the <a title="" href=" Casting call">Seattle Casting call</a>, or <a href="">Geeks on a Plane: Asia</a> . Oh yeah, and I'm doing a chickenblogging experiment unrelated to work (though tangentially related to Chris Pirillo) at <a href=""></a> . But that's because I get so many questions in social media channels about the chickens!)</p> <p>And part of it, the bar for this blog is getting higher. In the early days of blogging, typos were a sort of badge of authenticity and real-time meaning. With twitter and SMS and fat-fingered phone statuses, not only do typos in blog posts seem quaint, they seem inadequate. :P I can't compete with the autocorrect sites either cause of the nature of this blog demands it be safe for work! :)</p> <p>I don't believe blogs as a medium are dead. I personally am not dead, and I'm (possibly due to my lack of self-actualization and enlightenment) not yet willing to call this blog dead either. But more and more I feel like it's the place where you have to get Betsy brainmatter unrelated to what's going on in the Bing evangelism world, the twitter world, the FB world, and the "guest blogger around startups" world. Because all those worlds have their outlets and you see enough of me there. They key thing about this blog is that you can email me through the contact list. Straight into my work inbox (though you might want to tweet at me to remind me, if you think it might have been too long and/or caught by Microsoft corporate junk filters).</p> <p>That means the cadence of the writing here will of necessity slow down and the posts will all end up being longer. And topicwise, more about cyberculture and social media and women in tech. So for 2012, that's what you will see here. I've got a decent lifehackerish post in the works up next that will be my first of 2012. It will probably take me these two weeks (on vacation) to finish it (my how things change right - blogs used to be our twitter).</p> <p>So more in a bit, and thanks for your patience! 2012 will be an amazing year!</p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p><div style="clear:both;"></div><img src="" width="1" height="1">Betsy bet - why Bing reaches out to startups, and why a conference like this is fun in general<p>Last Friday I had the privilege of both speaking and mentoring at the inaugural BlogHer | bet conference, both as a Bing PR/marketing person and as social media/community application/games program manager. It's an unusual conference and so I'll lay out a bit of the format and then give some flavor of the event, which was held at the Microsoft campus in Silicon Valley.</p> <p> <img height="255" width="295" src="" border="0" /></p> <p>The number of attendees was gated on the number of mentors - each person got a one hour slot to pitch their business, ask technical/marketing/funding advice, and the rest of the time was filled with panels to help you get the leg up technically or investor-wise. During the time I mentored my two people (one per hour) , there was a startup "speed-dating" sort of circle where folks got practice pitching and introducing themselves - something I've seen before at BlogHer conferences but especially important here, where practicing that pitch for your business was important. Because I have been to a ton of technical tracks at conferences, I decided to focus on the entrepreneurial/funding tracks for my own development and of course, I was in the metrics panel close to the end of day. </p> <p>What I love about the BlogHer founders' mindset - Lisa Stone, Jory Des Jardins, and Elisa Camahort Paige - is that each project they do has as its subtext giving women a voice and empowering them to sit at the table. Bet was designed to answer the question "where are the women with big tech ideas" "where are the women who want to found tech companies" - and create a conference that gives those women a leg up. </p> <p>Here's what I learned...</p> <p><em>About mentoring...</em> the mentees were nervous to meet us, but being a useful mentor was actually nervewracking in its own way. I was fortunate in that I had different experiences because my mentees asked questions not only abou social media marketing but forums hosting, SEO/SEM, Web site and book cover design, holding events and managing email membership lists, and in general the refinement of their pitch. I texted my boss Stefan at a break that while I mock PR/marketing as an engineer, (and Stefan's hair to boot) the stuff I've learned directly and osmosis by sitting for two years on a PR team served me in good stead. You need to be able to explain your business and why you care about it in a paragraph or less. I told my mentees "the guys I meet at tech conferences can all do this. You gotta do this too."</p> <p><em>About pitching to VCs...</em></p> <p><strong>You need a strong team.</strong> VC, unless they are already friends, don't really go for one-woman shows the way they go for an exec team with a business plan and a rock star pedigree. There is no such thing as a wallflower CEO - the CEO has to be the one making the pitch (though it would help to have the CTO or other folks who are subject matter experts in the financials or the product there for demo). </p> <p><strong>Know your market/competitors - even if you are so new you think you don't have any.</strong> There are different ways to make your case, but there's no such thing as a <a href="">pitch deck</a> without a look at competitors. Think of it this way - the world is getting along fine right now sans your business (or they think they are) - you need to include your thinking around competition or potential competitors early, even if it's in the appendix. </p> <p><strong>People, Terms, Valuation:</strong> Lisa Stone, CEO of Blogher, relayed this great advice she got from <a href="">Caterina Fake</a> (Flickr, Hunch, Chairman of Board for etsy.com) when BlogHer itself was getting venture funding - prioritize yourself by People, Terms, and Valuation. If you assemble the right all-star team who is 100% behind your business idea, and get your business idea to a provable state faster, you will attract the right terms from VCs and a better valuation follows from it. If you are only interested in your valuation and the money you take from the company before the people, you are more likely to run into trouble and an outcome you don't want.</p> <p><strong>If you are lucky enough to get past the courting stage and are talking terms, you can never invest too much money in financial and legal advice.</strong> Have these professionals run models for you so that you know with each round of venture funding, how much you and your employees/prior investors' shares are diluted. VC investments - rule of thumb is they want a return of 10x their investment (if not more). So if you are asking for $1 million in funding, they want you to have a company valuation of at least $10 million - ie, they now own a stake ina $10 million business. I won't go into the lengthy legal terms covered in the term sheet panel but for folks close to this stage, it's likely worth the virtual access fees to see it. <a href=""></a> .</p> <p><strong>Where the pitch meets the money and ownership percentages is risk.</strong> If you already have a profitable business, with customers, and your goal now is scale, that's a way different risk than the company with a new idea that has no customers yet and wants funding to acquire some. Every time you pass a major milestone for the company, the valuation goes up. You may get told to come back to ask for funding once you have done X (gotten customers, built a prototype, etc). Ironically bigger/well-known firms tend to be "softer" about terms than smaller ones - they know that if the founder makes a great business that's the only way they win - having controlling stakes in a tanking company serves no one. </p> <p><strong>The best VCS help your business with more than money -</strong> the best VCs help you shape your company into a better one and its not supposed to be adversarial. While founders/owners may be skittish about giving up control at all, the better relationships are more like partnerships.</p> <p><strong>Metrics and measurement panel:</strong></p> <p>This was fun. I sat next to Amy Chang of Google Analytics and Laura Fitton (@pistachio), CEO of <a href=""></a> - Laura took notes and tracked all the tools we mentioned and put them <a href="">here</a> . I mentioned <a href="">The Goodness Engine ebook</a>, which was a cross-industry project to help Donorschoose.org, but which had lessons that apply to startups and new businesses (because like non-profits, they start with no money and stil have to drive traffic,engage customers, get donations, decide if they need an API or other feeds coming from their site, etc). The main reason I mentioned it in this context though is that the ebook shows how much metrics homework Donorschoose.org did, before baring their problems to our team of 30+ industry experts. Some of the metrics Donorschoose.org offered could be found in Google Analytics or on the twitter tools Laura mentioned - but some of them were innate to their unique business premise and value proposition. You really need to focus around your customers and where your cash flow for your business is coming from - if it's online advertising, then tools that measure user behavior on Web sites and actions they take, will be key. But only you and your database will know how many actual sales you got or consulting appoints you made - it's not just going to be handed to you by an off-the-shelf tool.</p> <p>Why do I love this kind of thing? Well, aside from the fact helping women in technology rocks, folks from Bing benefit in talking with startups and new business folks as much as they benefit from rapping with us. Yes, I reminded folks that Bing webmaster tools (<a href=""></a> ) is where you can learn how to ensure your site is noticed by Bing, and that helps get the word out beyond the SEO conferences, but it wasn't about shilling Bing so much as absorbing the energy and feeling part of that upstart uppityness that has to accompany any new venture. Bing still has a way to go, but like any startup hopefull we've got to justify spending and deliver on promise. It always feels good to tap into the energy of the upstart tribe :) </p> <p>Live it vivid!</p> <p> </p> <p> </p> <p> </p><div style="clear:both;"></div><img src="" width="1" height="1">Betsy and Facebook ate my blog (or possibly my brain)<p>I'm writing this from a skyscraper with a big window where I see exactly no snow falling, despite dire prediction. As we all know, the Seattle area can't handle snow - so much so that the *idea* of snow, keeps drivers at home.</p> <p>This is a somewhat decent metaphor for the idea that the micro-blogging or status-update applications will take over blogging functions in society, much like TV was supposed to destroy radio.</p> <p>But I have to admit that my purposeful blogging has gotten lighter, even as my thinking gets heavier. True, I did write these pieces for Blogworld - one about <a href="">how effective community outreach for a cause can be in turning up engaged users</a> and the other that represent <a href="">my top 10 learnings while building social or community-based applications, and doing social media marketing. </a> <a href="">Bing and the future of search on the Bing blog</a> too, and it makes more sense in most cases to post it there.</p> <p. </p> <p>We all know social media channels can be a distraction and all of them have gotten more popular and noiser. <a href="">Internet usage is up worldwide</a> and according to Pew, <a href="">3/4th of US online teens and young adults use social networks.</a>. </p> <p <a href="">trends of failure. </a>That's natural in a new medium - fail, I say, as fast as you can. And also, some things only work once while the medium is new - and then first mover advantage is used up and you are now just an online marketer like everyone else. </p> <p>The other thing that has informed my silent thinking/non-blogging brain lately has been the issues raised by Linda Stone and others about <a href="">continuous partial attention</a> and <a href="">what it means to have software that shuts off inputs so we can get things done.</a>.</p> <p).</p> <p>No, the blog as a medium is not dead - and this blog is not dead. But to do it right I will have to change my life (or at least the part inside my head) to suit. I'll let you know more how that goes. </p> <p>Live it vivid!</p><div style="clear:both;"></div><img src="" width="1" height="1">Betsy kid deserves a great education<p>Now that some of the launch madness of <a href=""></a> (aka <a href=""></a>) is over, I'd like to blog about what REDU campaign means to me.</p> <p>I'm a completely public-educated person. With the exception of nursery school (ie pre-kindergarten) I went to public schools in Massachusetts and California, and got university degrees in California and Washington from public universities. </p> <p>When I was somewhere between 4 years old and 8 years old (this era for me blurs a bit), the issue of <a href="">Japanese Americans being put in internment camps during World War II</a> was explained to me. Specifically, Japanese-Americans I know. My dad was about 5 years old when he got out, his parents were immigrants, and like many folks of my age, I had relatives who went there and some lost all they had. Talk about recession and losing money trying to sell your home - when people know that the government is forcing you out of your house and you are desperate, they know you will take any price. People could only take what you could carry. In those days there were no Xboxes or Nintendos, no big screen TVs, but try if you will to think about what you'd put in your laptop bag and suitcase and wheel down the street to your new home. </p> <p>So as a kid with a vivid imagination, I imagined all this. The feeling of being singled out, a freak, unwanted and forced to leave my school. Being scared to go somewhere strange and yucky with my family as a kid. Would this kind of thing ever happen to people I knew again? And in these discussions, my mom noted: "Your dad's family has always valued education because when you are packed off to internment camp, it's the one thing that can't be taken from you."</p> <p>Education is this amazing, invisible tool. It helps solve problems, create new possibilities, and fits into a laptop sleeve - it fits into any pocket and up any sleeve. When my relatives got out of internment camp, it was education (and freaking hard work) to get back all the physical, economic and social ground they had lost. The video on the REDU site "<a href="">The Education Crisis in Two Minutes</a>" has a great moving graphic that shows what happens when folks get a good education and can empower themselves in society. That's why education matters so much. It's a lever that rights things, helps the downtrodden, brings out solutions to problems.</p> <p>So REDU is personal to me and I'm personally glad we were able to launch it. Because I got so much of my life and superpowers from public education and it deserves some karmic payback, but also because I know that secret about what education really is. World War II is over but we still have social inequities and societal problems in this country. Education remains as a tool that can't be taken from the people who have it and they can still use it to change their world.</p> <p>Live it vivid!</p><div style="clear:both;"></div><img src="" width="1" height="1">Betsy the summer that struggles to arrive, I struggle to blog<p>A lot of people I ran into this past 12 months talked about it - the great blogging struggle. Some of them, who have a more entrepreneurial or consultant bent, have managed to keep blogging steadily even while picking up responsibilities to their audience in Twitter and Facebook. I, as you can see by my last blog post timing, fell far short of that. </p> <p>Some of it I have to admit is the "twitter ate my blog" syndrome. I find myself with less time to think involved thoughts, and the temptation of the twitter candy is that you have your 140 characters of fun, and then the urge to publish has been banished - along with whatever complicated thought I might have come up with after that. Some of it is twitter honing my insights to what they really should be - only worth a fortune cookie's worth of expression.</p> <p>Some of it has been noisy-ness and the act of keeping up with what folks are saying. I just finished re-reading Cognitive Surplus (Clay Shirky) and am about to start Delivering Happiness (Tony Hsieh) - and these are authors I've met and respect their brains. If I read every single social media book that claimed to give the marketer godlike powers, I'd have to quit my job and hire backup brains to help. I also respect enough of the discourse that I try not to clutter it with my own stuff too much if it's a bit "me-too."</p> <p>But some of what I feel emerging is some observations about being a tech person and being a marketing/PR person, and I'm not quite baked on the notion. I caused trouble with developers on past projects by bringing in customer data and I cause trouble in marketing circles by pointing out that the traditional media landscape is morphing. Aside from being a universal pain in the behind, there has to be some advantage to this dual view, and what i hope by end of summer is to be able to write here more on my findings while walking the periphery of both disciplines.</p> <p>Cheers, and hope where you are, there's more sun than Seattle. </p> <p> </p> <p> </p> <p> </p><div style="clear:both;"></div><img src="" width="1" height="1">Betsy Lovelace Day 2010: In honor of my mom of science<P>When I signed up to do this Ada Lovelace thing, I knew I'd have a few options on my hands. </P> <UL> <LI>I could research obscure women that needed to be brought out to public view.</LI> <LI>I could name women in tech or science you probably have heard of already (but possibly not as much as their male counterparts).</LI> <LI>Or I could go straight for home, to the first woman of science I ever met (since I shot out of her womb) - my mom.</LI></UL> <P>I'm mentioning my mom in part because I want to give encouragement out there to the working moms of tech and science, who think "yikes this is tough doing both" and need to know that the struggle matters.

That's what saved me (once the music started) - my most complex and entertaining story was the first one I told (and possibly could have been the only one I told, but I wanted to balance the presentation with more data). </LI> <LI>Ignite has it right - memorise your words and use vivid pictures. In my case I had to animate some twitter tweets because I was talking about them - but if you have a more visually oriented talk, go the Ignite route and do minimal words, big photo. </LI> <LI>For 140 Characters, I saw some presenters lose their audience (10 minute was the longest, so not even that long a period in which to lose people) by being dry and not conforming to the "story" format that Jeff Pulver really espouses. The best stories were human and vivid (Wm. Marc Salsberry's photos didn't work and he had us all weeping from the narrative of his foray into tech photography and the support for his brother dying of cancer).</LI> <LI>AV fallback = interpretive dance. I joked with my manager Stefan and coworker Aya that if I couldn't use the slide deck of the tweets I'd do an interpretive dance of what happened on launch night. I actually DID think of some poses I would have to do, if I got no visuals. That cracked me up and helped me mentally before going on stage. </LI></UL> <P>Venue</P> <UL> <LI>The Kodak Theater is a 3,000+ seat venue. This is where people receive their Oscars and by custom Jack Nicholson has his own marked chair. If you have a chance to speak here, do, but be prepared to think "Holy crap, this place is REALLY BIG!"</LI> <LI>The nice thing about Kodak is that it is a beautiful piece of architecture. There are lush balconies, an awesome sense of history, and while enormous, it doesn't quite scare the way a stadium or arena venue could, because it has STYLE.</LI> <LI>The AV guy, JT, was awesome but I wasn't used to the cameraman actually flipping from me to the screen of my laptop. Other panelists I talked to, who had to sit in front of monitors showing thier faces, also had eerie feelings. There may be no way to rehearse the sensation without being in the venue, but practicing in front of a mirror could help people get over their own faces.</LI></UL> <P><IMG style="WIDTH: 283px; HEIGHT: 280px" src="" width=352 height=381</P> <P>This photo is more of what I looked like to myself when the camera was on me and not my laptop. Lights are super bright when you are onstage -people warned me and it is true that you really can't see any faces in the audience.</P> <P>Garb</P> <UL> <LI>I wore a skirt thinking I'd be miked and walking around, but I actually ended up behind a podium (to work the laptop). This meant that a key element of my presentation,a 1920s style cloche, stole some of the show (which was fine by me, its an homage to the decor of the theater).

See you there!</P><div style="clear:both;"></div><img src="" width="1" height="1">Betsy is good, but not a replacement for the "old objectivity"<P>I was a newspaper reporter before I went into Web technology as a profession, and well before becoming any kind of blogger, so when I comment on journalism I have both perspectives ensconced in my brain. I was also a reporter before the journalism field took a lot of flack for lack of objectivity, so my expectations may surprise some of you jaded by disappointment in journalism.</P> <P>The title of this blog post riffs from a well-written piece by David Weinberger <A class="" href="" mce_href="">Transparency is the New Objectivity.</A> In his piece, he notes that the hyperlinked nature of online articles and blogs, which enable presentation of reference documents (ie, the materials used by a reporter to create a news story) create a more authoritative sourcing and thus more respect for that author's work. Also, he believes respect is fostered by an author's transparency with regard to personal and political views.</P> <P>In other words, if I know your political bent,and I see photos/scans of all the documents you used for Watergate, I'd believe you more 'cause I know where you are coming from. I could reconstruct for myself how you came to the conclusions of your news story, and agree with you based on that knowledge. </P> <P>While I am actually a fan of transparency, and it's nice especially for journalism students to be able to recreate the thought processes behind great investigative journalism, I'm not sure presentation of author views and reference material alone is enough to create the kind of journalism that was the goal of the "old objectivity." We can't afford to mistake the gloss of transparency for the heavy lifting objectivity in journalism was supposed to do.</P> <P><EM>Transparency of reference materials</EM></P> <P>Transparency will not always result in the most accurate reporting coming out. As I tweeted to Dare Obasanjo, what happens if your sources are people in Iran who are afraid for their lives, to go on the record. Do you not publish a blog post from Iran because you can't be 100% transparent about the sources?</P> <P>Another problem is that the kind of investigative journalism that creates social change (see Seattle Times Health <A class="" href="" mce_href="">special project on MRSA</A>) may require creating a new record of assembled data (a db for example). Do you as a reader now distrust the data because it was assembled by The Seattle Times and not an easily referenced document? How will you vet their db analysts? Will you look at the code to ensure they coded it right and their select statements are properly formed? </P> <P>Even if the reference materials are simple flat files and/or readable in a browser, will you as reader really have 5 hours reconstructing each detail of the Seattle Times data processes, or do you just want to look up the hospital near you to see if the doctors wash their hands? Why pay for the paper for access to this information if you have to re-create the reporting entirely yourself?</P> <P>Placing a higher value on linkable reference materials also brings out the question of coverage skewing toward what is easiest to link to. Will reporting just become groups of links to documents that are already public? Link to videos and photos that were already reported (but maybe presented the wrong experts or sources in the captions?) </P> <P>And while we are at this presentation of a collection of links, well, doesn't this notion sound like a search engine results page to anyone? I have yet to see anyone claim that a search engine can replace heavy-hitting, muckraker journalism. Why? Well, often a reporter has studied an area for far longer than the casual Web surfer, so the content value added in synthesizing the information will be higher (it's why you ask only certain people to help you fix your computer, and others you don't bother - the experienced people know what to look for and how to troubleshoot). </P> <P>But also, search engine results are presented in response to queries, and are dependent on the user knowing what terms to put into the box (this is why the bing user experience is so interesting, it tries to visually nudge you to get more of an idea what you really want back). If the searcher doesn't know what cognitive linkages to make between documents beforehand, it's not likely the materials would come back together. </P> <P>To get 3 document links back that resemble the 3 reference materials for a news story, you'd have to know what was in the docs, and their relationships to one another with regard to the investigative conclusion. In other words, you'd have to know the horrifying statistics of MRSA before you put down the search terms. This is why the term "human aggregator" doesn't begin to talk about what a good reporter does with information - they really have to analyze it enough to teach other people how to make these connections.</P> <P>Reliance on only linkable/readily transparent items creates other dynamics. Doesn't even have to be laziness but shortage of time...What if you are blogging nights and weekends and have a day job, without the time to look at older documents on microfiche at the courthouse or pull public paper records to affirm for yourself things got done? The temptation will be high to link to what's easy and write about what's easy and the bar will lower to ease of linkage. Really, only one rich news org has the resources to do any real reporting - then the rest of us just link to that, right? </P> <P>People hotly debated whether Techcrunch should have released the Twitter business documents they blogged about, but few really talked about whether actual journalism was being committed around the documents. (Michael Arrington would argue yes of course, but to Silicon Valley outsiders the docs themselves became news. In a j-school context, you could argue that the docs were really just one "fact check" against an emerging Twitter story that Techcrunch has not yet written and now may not ever write.)</P> <P><EM>Transparency of author viewpoint</EM></P> <P>Fear of a reporter skewing news coverage based on their background, political views or opinion is at the heart of the objectivity debate. However, this fear of non-objectivity applies to other professions as well and people tend to forget that. </P> <P>Every day, you hope that your doctor doesn't mind treating people of different political views than her, and will prescribe you the right medicines for your cold regardless of your choice of vacation home. You hope that your bus driver drives the same (safe) way regardless of who is on his bus. You hope the guy giving you the fries and hamburger didn't spit into your food because he hated the rock band on your t-shirt. Heck, people work with people all the time that they can't stand, and for professionalism's sake, they put personal feelings aside. </P> <P>It's so interesting that people more readily trust there isn't spit in their Coke, but are sure that a reporter is hiding something from them.</P> <P><EM>What were my own standards of objectivity?</EM></P> <P>Here's what I understood to be my standard of objectivity, when I was in the journalism profession. I was told by one news editor early in my career that essentially if everyone disagreed with the "bias" of my story - all the special interest groups opposing each other hated it equally- there was a likelihood I had hit the sweet spot of objectivity. I was supposed to get along with my sources, but they were not supposed to be my best friends, and they should not be able to guess which way I would vote in an election. They should not see me as biased against their religion or point of view. To do my job well, both sides had to trust I'd represent their point of view fairly (or at least piss off the other side equally).</P> <P>So to do a good job, I had to be free to aggravate everyone, because the truth is often complex, hard to get at, and debateable, and if I was always worrying about pleasing people in power or high in celebrity quotient, I wouldn't be representing the truth correctly. The newspaper would stand behind me, protect my notebook (paper not digital), and bail me out of jail for the stories I wrote when powerful public figures or companies went after me. In return, I had to be meticulous in my accuracy, get as much on the record as possible, and as scrupulous about representing as many points of view as would fit in a 6-20 column inch space. It helped that both states I worked in had decent public records laws and my note-taking verbal memory was really good. And I had good editors, who took out things from my stories they felt weren't decently backed up or were redundant and therefore presenting too much of one source's point of view. </P> <P>Transparency meant something other than documentation or stating my political views of the moment- it went straight to the heart of where I got my money from. If I had ever worked for an organization, owned stock in that organization, had relatives in an organizaation, I either did not cover the story or (as sometimes you see in MSN Money) I would have had to disclose my interest "this columnist owns 5 shares of stock in Microsoft." The appearance of being unable to cover a topic area fairly was good enough to keep me from it. Mostly, journalism kept me out of public activism because as a cub reporter I really didn't want to close down story areas I could write in. Other journalists who were more established (ie, could focus on one beat) could afford to have private causes not related to their beat.</P> <P>BTW, I found I always had more notes and material than I could fit into a news story. It wasn't sinister, it's that people hate reading anything long.</P> <P>Even as a freelance book reviewer, which is pure opinion, The Seattle Times constantly ensured I was reading books by people I didn't know, or have any ties to. Being "out of the scene" was helpful because it meant I didn't have a social or political agenda to like or dislike the books. </P> <P>This is the kind of self-policing relative to a standard of objectivity. A standard of transparency for online journalism might help someone get caught violating the standards of objectivity and fairness but I think the root issues would still remain: did you try to get an objective truth? is the article or post accessible to people of all persuasions and initial points of view? Do you have documents, facts, quotes, witnesses to back up the conclusions of your piece? Are you being a lazy journalist/blogger, or are you digging deeper even as you seem sure the conclusion can be reached for this piece? Have you annoyed everyone equally, even the people you are supposed to be in the pockets of?</P> <P mce_keep="true">So, while I think transparency is good, I don't think it replaces the old goals of good journalism and transcending the reporter's personal point of view to get the complete story out. Empathy is key to good journalism and blog reporting- the ability to put yourself in the flood victim or the astronaut's shoes as they tell their stories. A piece of reporting that goes beyond him/herself to reach other people is usually the most powerful kind of reporting and I'm not sure a page full of links can take the place of that human processing information for a public/purpose well beyond the personal.</P><div style="clear:both;"></div><img src="" width="1" height="1">Betsy and a decent shot of courage<P>I <A href=""></A> and like any new community site it is in a constant state of improvement.) </P> <P>There's a lot of blogging and tweeting going on about <A class="" href="" mce_href="">bing<.</P> . </P> <P>Those employees' feedback made bing what it is today.

asprintf. It takes a

Quarkus is designed as a container-first framework optimized for high speed, low memory usage, and great scalability. The container-first strategy bypasses the configuration issues and countless updates that may come along with monolithic server systems by bundling together the runtime environment and application code.
Initially, Quarkus was created to support native code for Graal/SubstrateVM, but it also works with JVM and OpenJDK HotSpot. Quarkus supports many industry-standard libraries such as Hibernate, Kubernetes, RESTEasy, and Eclipse MicroProfile.

Quarkus was created to be utilized in microservice and serverless environments as well as reactive programming models. It uses JAX-RS for the REST endpoints, JPA to preserve data models, and CDI for dependency injections.
Through this post, you’ll learn how to use Java and Quarkus to create a REST API with JAX-RS, and secure it with OAuth 2.0 and Okta.
This tutorial is a modified and updated version of the “Quarkus — Using JWT RBAC” tutorial on the Quarkus website. The main difference is that this tutorial will use Okta as the OAuth provider and the OIDC Debugger to generate tokens for ad hoc testing (instead of rolling the whole thing yourself).
Let’s get started!
Install Quarkus Tutorial Prerequisites
You’ll need to install a few things before you get started.
Java 11: This project uses Java 11. OpenJDK 11 will work just as well. Instructions are found on the OpenJDK website. OpenJDK can also be installed using Homebrew. Alternatively, SDKMAN is another great option for installing and managing Java versions.
Just a hint, if you run
mvn -v, you’ll see your Maven version AND the Java version Maven is running on.
On my computer (a Mac), I was able to use the following command to set the shell in which Maven was running to Java 11:
export JAVA_HOME=$(/usr/libexec/java_home -v 11).
HTTPie: This is a simple command-line utility for making HTTP requests. You’ll use this to test the REST application. Check out the installation instructions on their website.
Okta Developer Account: You’ll be using Okta as an OAuth/OIDC provider to add JWT authentication and authorization to the application. Go to our developer site and sign up for a free developer account.
Create a Java Quarkus Project
Open a terminal and
cd to an appropriate parent directory for your project. The command below uses the
quarkus-maven-plugin to create a starter application and places it in the
oauthdemo subdirectory.
mvn io.quarkus:quarkus-maven-plugin:0.23.1:create \ -DprojectGroupId=com.okta.quarkus \ -DprojectArtifactId=oauthdemo \ -DclassName="com.okta.quarkus.jwt.TokenSecuredResource" \ -Dpath="/secured" \ -Dextensions="resteasy-jsonb, jwt"
If you run the project at this point, you’ll get an error because you need to define some application properties first.
Configure Quarkus Application Properties
Open the
src/main/resources/application.properties file and copy and paste the following into it.
mp.jwt.verify.publickey.location=https://{yourOktaDomain}/oauth2/default/v1/keys mp.jwt.verify.issuer=https://{yourOktaDomain}/oauth2/default quarkus.smallrye-jwt.auth-mechanism=MP-JWT quarkus.smallrye-jwt.enabled=true
You’ll need to fill in your Okta developer URI in two places.
To find your developer URI, open your Okta developer dashboard and navigate to API > Authorization Servers. Look at the row for the
default auth server where you’ll see the Issuer URI.
That domain is your Okta URI that you’ll need to populate in place of
{yourOktaDomain}.
Test the Default Quarkus Endpoint
Navigate into the project directory:
cd oauthdemo.
Run the project:
./mvnw compile quarkus:dev
You should see output like this:
[INFO] Scanning for projects... [INFO] [INFO] ---------------------< com.okta.quarkus:oauthdemo >--------------------- [INFO] Building oauthdemo 1.0-SNAPSHOT [INFO] --------------------------------[ jar ]--------------------------------- [INFO] ...

If you get an error, first check which version of java Maven is using.
./mvnw -v
Now, in another terminal window, use HTTPie to test the generated endpoint:
$ http :8080/secured HTTP/1.1 200 OK Connection: keep-alive Content-Length: 5 Content-Type: text/plain;charset=UTF-8 hello
Pretty sweet! But we can do a little better.
Replace the
src/main/java/com/okta/quarkus/jwt/TokenSecuredResource.java file with the following:
package com.okta.quarkus.jwt; import java.security.Principal; import javax.annotation.security.PermitAll;.JsonWebToken; /** * Version 1 of the TokenSecuredResource */ @Path("/secured") @RequestScoped public class TokenSecuredResource { @Inject JsonWebToken jwt; @GET() @Path("/permit-all") @PermitAll @Produces(MediaType.TEXT_PLAIN) public String hello(@Context SecurityContext ctx) { Principal caller = ctx.getUserPrincipal(); String name = caller == null ? "anonymous" : caller.getName(); boolean hasJWT = jwt != null; String helloReply = String.format("hello + %s, isSecure: %s, authScheme: %s, hasJWT: %s", name, ctx.isSecure(), ctx.getAuthenticationScheme(), hasJWT); return helloReply; } }
Now, save the file and test the new, updated endpoint:
$ http :8080/secured/permit-all HTTP/1.1 200 OK ... hello + anonymous, isSecure: false, authScheme: null, hasJWT: true
Did you notice how you didn’t need to re-start or re-compile your application for the new endpoint to work? That’s one of the slickest features of Quarkus!
Next, we’ll add OAuth 2.0 support to the application.
Create an OIDC Application in Okta to Test Your Quarkus Service
Head over to your Okta developer dashboard — if this is your first time logging in, you may need to click the Admin button.
From the top menu, click on the Application button and then click Add Application.
Select application type Web and click Next.
Give the app a name. I named mine “Quarkus Demo”.
Under Login redirect URIs, add a new URI:.
Under Grant types allowed, check Implicit (Hybrid).
The rest of the default values will work.
Click Done.
Leave the page open or take note of the Client ID. You’ll need it in a bit when you generate a token.
Update TokenSecuredResource
Now update the
TokenSecuredResource class to do two things:
1) Use CDI dependency injection to inject the
groups claim from the JWT, if it’s available.
2) Add a default endpoint for the
/secured path that is protected by OAuth 2.0 and requires the
Everyone group to access.
Change
TokenSecuredResource.java to the following:
package com.okta.quarkus.jwt; import java.security.Principal; import java.util.Set; import javax.annotation.security.PermitAll; import javax.annotation.security.RolesAllowed;.Claim; import org.eclipse.microprofile.jwt.JsonWebToken; /** * Version 1 of the TokenSecuredResource */ @Path("/secured") @RequestScoped public class TokenSecuredResource { @Inject JsonWebToken jwt; @Inject @Claim("groups") private Set<String> groups; @GET() @Path("permit-all") @PermitAll @Produces(MediaType.TEXT_PLAIN) public String hello(; } @GET() @Path("/") @RolesAllowed({"Everyone"}) @Produces(MediaType.TEXT_PLAIN) public String helloRolesAllowed(; } }
Try out the new default endpoint:
$ http :8080/secured HTTP/1.1 401 Unauthorized ... Not authorized
Generate an OAuth 2.0 Access Token to Test Authentication in Quarkus
Open the OpenID Connect Debugger. You’re going to use this page to generate a JWT access token that you can use to authenticate.
Follow the below steps to continue:
- Set the Authorize URI to:
https://{yourOktaDomain}/oauth2/default/v1/authorize
- Copy your Client ID from the Okta OIDC application you created above and fill it in under Client ID
- Change the scope to be
openid email profile
- Add something for State. It doesn’t matter what. Just can’t be blank
- Scroll down. Click Send
- Copy the resulting JWT Access Token to the clipboard, and in the terminal where you are running your HTTPie commands, save the token value to a shell variable, like so:
TOKEN=eyJraWQiOiJxMm5rZmtwUDRhMlJLV2REU2JfQ...
Test the JWT With the Protected Quarkus Endpoint
Now that you have a valid JWT from your OAuth provider (Okta), you should be able to use this JWT to authenticate against the protected endpoint.
Try it out:
http :8080/secured "Authorization: Bearer $TOKEN"
You should see something like:
HTTP/1.1 200 OK Connection: keep-alive Content-Length: 123 Content-Type: text/plain;charset=UTF-8 hello + andrew@gmail.com, isSecure: false, authScheme: MP-JWT, hasJWT: true, groups: [Everyone, Admin]"
Add Functionality to Quarkus REST Endpoint
The first step to building a more realistic REST resource is to create a data model class. To do this, you can use a helper project called Lombok (more on their website).
To work with Lombok, add the following dependency to your
pom.xml.
<dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.8</version> <scope>provided</scope> </dependency>
NOTE: If you’re using an IDE to build your project, and not the command line, install the Lombok plugin for it. For example, see the Lombok IntelliJ plugin.
You’re only going to use a small part of Lombok, the
@Data annotation, to save time writing boilerplate code in the data model class (check out the annotation docs, if you like). It generates getters, setters,
equals(), and
hashCode() methods.
Go ahead and create a Java class:
src/main/java/com/okta/quarkus/jwt/Kayak.java.
package com.okta.quarkus.jwt; import lombok.Data; import java.util.Objects; @Data public class Kayak { private String make; private String model; private Integer length; public Kayak() { } public Kayak(String make, String model, Integer length) { this.make = make; this.model = model; this.length = length; } }
You may have guessed by now that your new REST endpoint is going to manage a list of kayaks.
This code is pure JAX-RS and is not specific to working with Quarkus or Kubernetes. JAX-RS is the Java API for Restful Web Services, an annotation-based specification for configuring REST services. Because it’s just a spec, the actual implementation is provided by the Quarkus stack.
Now, you need to create the REST endpoint resource:
src/main/java/com/okta/quarkus/jwt/KayakResource.java.
package com.okta.quarkus.jwt; import java.util.Collections; import java.util.LinkedHashMap; import java.util.Set; import javax.annotation.security.RolesAllowed;.core.MediaType; @Path("/kayaks") @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.APPLICATION_JSON) public class KayakResource { private Set<Kayak> kayaks = Collections.newSetFromMap(Collections.synchronizedMap(new LinkedHashMap<>())); public KayakResource() { kayaks.add(new Kayak("NDK", "Romany", 17)); kayaks.add(new Kayak("NDK", "Surf", 16)); kayaks.add(new Kayak("P&H", "Scorpio HV", 15)); } @GET public Set<Kayak> list() { return kayaks; } @RolesAllowed({"Everyone"}) @POST public Set<Kayak> add(Kayak kayak) { kayaks.add(kayak); return kayaks; } @RolesAllowed({"Everyone"}) @DELETE public Set<Kayak> delete(Kayak kayak) { kayaks.remove(kayak); return kayaks; } }
I won’t go into a ton of detail here, but I do want to point out a few things. First, notice the
@Produces and
@Consumes annotations. The Quarkus docs state that it is very important to include these as they’re used to optimize the final build. This endpoint uses JSON, specified by the constant
MediaType.APPLICATION_JSON.
Also, notice that the GET endpoint is public, but the POST and DELETE endpoints require membership in the
Everyone group. Don’t confuse
Everyone with anonymous.
Everyone is a catch-all, default group assigned to anyone that authenticates on the Okta OIDC application. In this instance, it means that a user has authenticated but isn’t necessarily part of any other group, such as
Admin.
Test Your Quarkus Endpoint and Add a New Kayak
Since you added a new dependency to your
pom.xml, you’ll need to restart the Maven process running your server.
Then, test the POST endpoint without a token to verify that it’s protected.
$ http POST :8080/kayaks make="P&H" model="Cetus HV" length=18 HTTP/1.1 401 Unauthorized ... Not authorized
Now, try again with the token. You’ll see that a new kayak has been added to the list!
$ http POST :8080/kayaks make="P&H" model="Cetus HV" length=18 "Authorization: Bearer $TOKEN" HTTP/1.1 200 OK Connection: keep-alive ... [ { "length": 17, "make": "NDK", "model": "Romany" }, { "length": 16, "make": "NDK", "model": "Surf" }, { "length": 15, "make": "P&H", "model": "Scorpio HV" }, { "length": 18, "make": "P&H", "model": "Cetus HV" } ]
You can delete the newly added kayak with the following command:
http DELETE :8080/kayaks make="P&H" model="Cetus HV" length=18 "Authorization: Bearer $TOKEN"
You might notice there’s no PUT (update) in this service. In a more complete service, each record would have a unique ID of some type associated with it. This would allow a client app to specify a specific record for update and deletion (instead of using the record properties themselves and the
equals() method).
Also, clearly, this resource is pretty naive, storing the data in a class property. In a real application, JPA annotations could be used to map the data model to a database for easy serialization and deserialization.
Learn More About Java, Quarkus, and Token Authentication
All done! In this tutorial, you used Quarkus and Java to create a simple REST service, secured with JWT OAuth using Okta as an OAuth/OIDC provider. You also saw how to use CDI dependency injection to inspect JWT claims and retrieve information about the authenticated (or not) client. Finally, you tried some of the basics of RBAC (role-based authentication).
As a reminder, this tutorial was inspired by the Quarkus post: Using JWT RBAC.
Quarkus has a ton of other great guides on their website.
You can find the source code for this tutorial at oktadeveloper/okta-quarkus-example.

GNOME Power Manager already has quite a comprehensive DBUS API to allow it to interface with stuff like the brightness applet and gnome-logout screens.
Brightness applet working hand-in-hand with g-p-m
I think this is something that should be cross-desktop compatible, so that XFCE, KDE and GNOME applications can all play nicely. Something like a session service name of org.freedesktop.PowerManagement would be lovely. Of course, this requires standardization of a set API, which traditionally has been hard to agree on.
I've put up a list of the new DBUS API that gnome-power-manager presents, but before anyone stresses out about API compatibility the old API is present as well, except not documented there.
Please have a look through and tell me about any method or signal naming funnies, or areas that don't look right – or even descriptions that don't make sense to mere mortals. When I've got some initial feedback, I'll make the important changes to the new API, and suggest just the “required” DBUS methods to xdg-list for comments about using a org.freedesktop namespace.
p.s. Don't comment too much about the Register() and UnRegister() methods yet, they are just stub functions at the moment, and not tested by gnome-power-self-test at all.
Thanks for any help,
Richard.
One response to “Desktop Power Management”
A method to retrieve the system idle time would definitely be useful, right now you have to poke X to provide this. I'd also include more options for device powermanagement, for example CPU, harddisks, wireless card and others as you already included with display. And while at it, shouldn't the screensaver be able to told to lock the display? | http://blogs.gnome.org/hughsie/2007/01/08/desktop-power-management/ | CC-MAIN-2014-52 | refinedweb | 294 | 58.82 |
#include <CGAL/linear_least_squares_fitting_2.h>
computes the best fitting 2D line of a 2D object set in the range [
first,
beyond).
The value returned is a fitting quality between \( 0\) and \( 1\), where \( 0\) means that the variance is the same along any line (a horizontal line going through the centroid is output by default), and \( 1\) means that the variance is null orthogonally to the best fitting line (hence the fit is perfect).
It computes the 2D best fitting line (in the least squares sense) of a set of 2D objects such as points, segments, triangles, iso rectangles, circles or disks.
The best fitting line minimizes the sum of squared distances from all points comprising these objects to their orthogonal projections onto the line. It can be shown that this line goes through the centroid of the set. This problem is equivalent to search for the linear sub-space which maximizes the variance of projected points (sum of squared distances to the centroid). Internally we solve this problem by eigen decomposition of the covariance matrix of the whole set. Note that the \( 2 \times 2\) covariance matrix is computed internally in closed form and not by point sampling the objects. Eigenvectors corresponding to large eigenvalues are the directions in which the data has strong component, or equivalently large variance. If one eigenvalue is null the fit is perfect as the sum of squared distance from all points to their projection onto the best line is null. If the two eigenvalues are the same there is no preferable sub-space and all lines going through the centroid share the same fitting property.
The tag
tag identifies the dimension to be considered from the objects. For point sets it should be 0. For segments it can be 1 or 0 according to whether one wants to fit the whole segment or just their end points. For triangles it can range from 0 to 2 according to whether one wants to fit either the triangle points, the segments or the whole triangles. For rectangles it can range from 0 to 2 according to whether one wants to fit either the corner points, the segments, or the whole rectangles. For circles it can be 1 or 2 according to whether one wants to fit either the circles or the whole discs. For triangles it ranges from 0 to 2 according to whether one wants to fit either the points, the segments or the whole triangles.
The class
K is the kernel in which the value type of the
InputIterator is defined. It can be omitted and deduced automatically from the value type.
The class
DiagonalizeTraits_ is a model of
DiagonalizeTraits. It can be omitted if Eigen 3 (or greater) is available and
CGAL_EIGEN3_ENABLED is defined: in that case, an overload using
Eigen_diagonalize_traits is provided.
Requirements
InputIteratormust have a value type equivalent to
K::Point_2or
K::Segment_2or
K::Triangle_2or
K::Rectangle_2or
K::Circle_2.
lineis the best fitting line computed.
centroidis the centroid computed. This parameter is optional and can be omitted.
tagis the tag identifying the dimension to be considered from the objects. It should be one of
Dimension_tag<0>,
Dimension_tag<1>or
Dimension_tag<2>. Also, it should not be of dimension greater than the geometry of the object. For example, a
Segmentcan not have a

TORONTO (ICIS)--Canadian chemical sales fell 1.1% to Canadian dollar (C$) 3.84bn ($3.92bn) in October from September this year, a statistics agency said on Friday.
Compared with October 2011, chemical sales were down 5.0% year on year, Statistics Canada said.
Meanwhile, sales in ?xml:namespace>
The declines were partly offset by higher petroleum and coal products sales, as well as increased sales for wood product industries, the agency said.
Compared to October 2011, overall manufacturing sales were up 0.1%.
October manufacturing inventories were C$66.2bn, up 1.3% from September and up 2.1% year on year from October 2011.
The inventory-to-sales ratio was 1.36 in October, compared with 1.32 in September and 1.33 in October 2011. The ratio is a measure of time, in months, that would be required to exhaust inventories if sales were to remain at their current level.

I'm having trouble with getting multiple dynamic inheritance to work. These examples make the most sense to me(here and here), but there's not enough code in one example for me to really understand what's going on and the other example doesn't seem to be working when I change it around for my needs (code below).
I'm creating a universal tool that works with multiple software packages. In one software, I need to inherit from 2 classes: 1 software specific API mixin, and 1 PySide class. In another software I only need to inherit from the 1 PySide class.
The least elegant solution that I can think of is to just create 2 separate classes (with all of the same methods) and call either one based on the software that's running. I have a feeling there's a better solution.
Here's what I'm working with:
## MainWindow.py
import os
from maya.app.general.mayaMixin import MayaQWidgetDockableMixin
# Build class
def build_main_window(*arg):
class Build(arg):
def __init__(self):
super( Build, self ).__init__()
# ----- a bunch of methods
# Get software
software = os.getenv('SOFTWARE')
# Run tool
if software == 'maya':
build_main_window(maya_mixin_class, QtGui.QWidget)
if software == 'houdini':
build_main_window(QtGui.QWidget)
# class Build(arg):
# TypeError: Error when calling the metaclass bases
# tuple() takes at most 1 argument (3 given) #
## MainWindow.py
import os
# Build class
class BuildMixin():
def __init__(self):
super( BuildMixin, self ).__init__()
# ----- a bunch of methods
def build_main_window(*args):
return type('Build', (BuildMixin, QtGui.QWidget) + args, {})
# Get software
software = os.getenv('SOFTWARE')
# Run tool
if software == 'maya':
from maya.app.general.mayaMixin import MayaQWidgetDockableMixin
Build = build_main_window(MayaQWidgetDockableMixin)
if software == 'houdini':
Build = build_main_window()
The error in your original code is caused by failing to use tuple expansion in the class definition. I would suggest simplifying your code to this:
# Get software software = os.getenv('SOFTWARE') BaseClasses = [QtGui.QWidget] if software == 'maya': from maya.app.general.mayaMixin import MayaQWidgetDockableMixin BaseClasses.insert(0, MayaQWidgetDockableMixin) class Build(*BaseClasses): def __init__(self, parent=None): super(Build, self).__init__(parent) | https://codedump.io/share/xuDtzlzAEpgg/1/python--multiple-dynamic-inheritance | CC-MAIN-2017-51 | refinedweb | 339 | 50.73 |

RipIt replied to RipIt's topic in For BeginnersThank you very much,caldier that was very helpful and yes Daaark i can read the site. I haven't yet but i am going to look at it now!
RipIt replied to RipIt's topic in For BeginnersI would but due to the nature of where i am (afghanistan) i cannot open pages such as games and certain other things due to being blocked by filter through the ACL. I will give it a try and look into all this when i return (jan-feb) but for now i am just trying to grasp basic knowledge of the things i can and cannot due in certain languages and which languages are easier / more apt for certain things such as text based RPG through browser and what not. i appreciate all the help you have provided me and i will continue to use these forums for a long time to come, asking for help and providing where i can haha.
RipIt replied to RipIt's topic in For BeginnersOk, thank you, i am trying to get a grasp as i am learning the basics to C++ and will soon use some type of graphics library with it to practice drawing maps / tile based screens through an array? i think thats how its done, from what i have read so far. still not sure about all that lol.?
RipIt posted a topic in For BeginnersI am curious as to what i could use to create these games in without having the bottleneck be the language / library / API--not sure if those are the right terms, still new a bit to it all. ) : [b]Or:[What would that mean for graphics and game play / user accesibility? (the porting to HTML5 part)
RipIt replied to RipIt's topic in For BeginnersSo pertaining to Text-based online RPG's i could use C++ for all of it, or i could use it for just the server side -also i can use python for this as well? Or i could use javascript for all my needs? I feel like i may have missed something so im just trying to clarify What would be the "best" language to create the following, if its this simple, im still a bit lost lol sorry. Text-based RPGSo if the support for Java in browsers is going to "die" what will then happen to such things like runescape or games like?

Sorry if i came / come off as pushy or a jerk. not my intentions :/
RipIt replied to RipIt's topic in For BeginnersI am thinking more like Runescape as i played this game since it first started to just recently. Except mine would obviously be much worse movement and graphics, even worse than when Runescape started, haha. Thank you so much for this information as it has helped me a lot. So if i were to want to do the Runescape type game, i could use say Java for an online RPG text based as well as long term Runescape type game? So i could use C++ for the server side / game engine ? and Java as the actual game code ? i may be confused to this part still.
RipIt replied to RipIt's topic in For BeginnersI posted the above as you were typing that up, sorry lol.
RipIt replied to RipIt's topic in For Beginners]
RipIt replied to RipIt's topic in For BeginnersThis help's a lot. Yes i want to start with a "simple" and "basic" game. i guess it just seemed a bit too simple in my head and i like to push ahead for results of what i want (impatient) lol. So with your post and the prior post about c++ and SFML, would c++ and sfml be the ideal language to use / continue learning for a BASIC GAME and then move to an online RPG (eventually)? I haven't made tetris or pong yet, i am deployed right now and i cant download the SFML due to blocked sites / restrictions on downloads :/ I am just reading C++ for dummies and using the contained CD with code::blocks and various internet sites for help like this site and cplusplus.com It's really just a learning phase and planning phase for things i would like to happen when i get back with making games like tetris and pong in between then and hopefully if time permits a tiny 2D basic game.
RipIt replied to RipIt's topic in For BeginnersOk, so in order to make a multiplayer 2D online topdown RPG Javascript and python would be better? I thought C++ was used to make tons of games now a days?
RipIt replied to RipIt's topic in For BeginnersHow would i go about setting up a server for that situation i guess is my problem / question. What are free resources i could use to host it on a server i have at my house?
RipIt posted a topic in For BeginnersSooo..Not sure quite where im going with this but my goal by the end of next year is to make a BASIC 2D top-down RPG that allows users to go to a website and login and play the game online with other players. I am learning C++ and SFML. using code::blocks Thank you for all the help and i hope this is a good explanation of what i want / am asking you.

Using Rails to upload files manually and how you can do it even cleaner using Carrierwave
So file uploading is the next feature we want to add to our application, and we're going to talk about how to do this in pure rails, as well as using the carrierwave gem to simplify things considerably. So, what do we want to upload files for? Well, our books like "Mastery" could use a bit of sprucing up, they could use an image for the book cover, and it would be nice if we could click on "Edit" and see a file field and be able to upload an image there. So that's what we're going to do. This is pretty straightforward, however. When we do this, we're going to need to do a fair amount of work because we have to understand how rails works internally a little bit, so that we can place the files in the proper directory so that they're available for the browser. So if we jump into our terminal, and we take a look at the public folder, this is pretty special. So the public folder** is static files that are served up by your web server and they hit before rails does. So if you type "404.html", it will bring up the 404 page just like you see here, but this is not being served up through rails. It sees 404.html inside this folder, and it immediately serves it up, so there's no processing going on, there's no database lookups or hitting your rails routes or any of those things. It sees the file name and it serves it up. If this didn't exist, it would go through rails and look for a route and go though the regular process, but it doesn't because this url matches exactly that. So we're going to take advantage of this knowledge, and we're going to put it here, a folder for the book in the book covers. So we're going to have to design how that works so that we can properly implement this and handle it. In our terminal, we can go into the same public directory and list out the files. And if we think about it, this is the perfect place to put our uploaded images. We can store them here, and they'll be served up without ever processing through rails, which will be very quick compared to going through rails, since they're static files. So in here, we want to separate everything out very cleanly because things can change in the future, and we want to be ready for that. So for now, we're just uploading images for books, but what if we want to add avatars for users later on? Well, that means we should separate those out into folders at the hightest level. So if we make a directory called books, here we can store all of the images and file uploads for books. If we make images and avatars for users, then we can have a users one, and separate those two out cleanly.
Let's talk about what else could change, what if our books have multiple images, what if we have an image for the book cover? For the back of the book? What if we have an image for the author? All of these mean that we could have more folders inside of here for every single book. So at the next level, we want to add a folder for a dynamic folder name that is the book database id, or the database slug. We're going to use the database id because the slugs can change, and we're just going to stick with the id's to keep it simple. So book number two is "Mastery", and we're going to hard-code an image in here and test it all out. So if we create book number two here and we dive into that, then we can talk about what we just mentioned where what if the book has a cover, a back cover or an author image? So in here, we want to separate those out. We don't have those yet, but we want to think about it in case we ever do, so here we're going to put the cover folder, and then inside the cover folder, you're going to upload the file directly into this folder. I'm going to simulate thay by just copying an image in here and saving it. So we could rename the images, but it really doesn't benefit us that much. If we keep the original filename, we can save this mastery_cover.jpg into the database and then our book knows that it does have a cover. So if our field is empty in our database record, then it knows that there is no cover, and we can use regular rails ActiveRecord code to skip the image, and if it does have one, it can look and point the image tag to this folder. So this is how we want to structure the folders in the image uploading at the very lowest level on your file system. So if we dive into our code in the show view, we can do something like this, which is still somewhat hardcoded. So we can say there's an image tag for
/books/#{@book.id}/cover/Mastery_Cover.jpg, and if we open this up in our browser, the image loads. So this knows to automatically look for the image where we stored it, and if your paste the image url into your browser, you can see that its books/2/cover/Mastery_Cover.jpg, which is exactly the same folder and file name as we just created in our terminal. Now that we've figured out where we want to save our images on disc, we can go to the edit form and the new form and begin adding the file upload field as we had planned in the very beginning. So we need to add the field, we need to have it save the file, and we also need to save the file name into the database record. So let's start with the form
app/views/books/_form.html.erb
//... <div class="form-group"> <%= f.label :cover %> <%= f.file_field :cover %> </div>
Now if we refresh the page, we have a cover attribute that we can upload. So if we upload the mastery cover again, and update book, nothing changed, nothing crashed, but it didn't actually do anything and the reason why is because if we go to our rails logs, we can come back to the PATCH method that we just saw, and we can see unpermitted parameters cover. So the cover file is being uploaded, and as you can see here, it is an action dispatch uploaded file instance, it has a temp file assigned to it, and we can see the file name and the content type and everything about it. and that means that our file is being uploaded correctly, however, we're just ignoring it when we recieve it. So we need to go into our books controller to actually allow it to happen. So if you jump down at the bottom, you can add cover into the book params method as a permitted attribute. So this will now allow the cover image to be submitted, and it will try to assign it to the book. However on the book, we don't actually have anything but FriendlyID on there, we've never added the method for this cover, and we don't even have an attribute for the cover file name that we need to save. So let's start there. Let's go into our terminal and generate a migration called
rails g migration AddCoverFilenameToBooks cover_filename
rake db:migrate
We finally have everything we need to actually upload and process this image, and that's what we're going to do now. so if we add an
attr_accessor :cover this allows the controller to assign the image we uploaded to the cover attribute on this book, and then we can go doing the actual saving into the file system where we want. So if we add an after_save callback and we'll call it
save_cover_image, this allows us to take that temporary file that we uploaded and really save it into the public directory like we talked about. So we only want to do this if there's a cover image. So if this is nil, then we won't try to save the image again. So then we can add
app/models/book.rb
class Book < ActiveRecord::Base extend FriendlyId friendly_id :name, use: :slugged attr_accessor :cover after_save :save_cover_image, if: :cover def save_cover_image filename = cover.original_filename folder = "public/books/#{id}/cover" FileUtils::mkdir_p folder f = File.open File.join(foler, filename), "wb" f.write cover.read() f.close self.cover = nil update cover_filename: filename end end
So what this does very simply is it creates the folder, it writes the file to it, and then it updates the book record with the filename. So we can add a new file, a different file name and it will always know which one to point to, and
self.cover = nil is very important, because if you don't have it, it will go into an infinite loop and continue trying to save this cover image over and over and over again. Now that we have the file uploading working, we can go into our show action, and we can remove the hardcoded file name that we had before, and replace it with
Book.cover_filename if Book.cover_filename?, so this will only display the image if the book has had an image uploaded for it. So now we can go into our public folder again, and let's remove the images that we have, and the folder that we created before, and then we can go to our application, we can go into "Mastery", there is no image being displayed, and if we edit and we upload Mastery's cover image, now it displays, and now if we go back and we go to "How to win friends and influence people" and do the same thing, we can see that it also displays properly. If we go into one of the books that I haven't played with, you can see that there's no image here. Well this code isn't terribly complex, it starts to get pretty nasty if we start adding in image editing like cropping and resizing, and even doing work like uploading these images to Amazon s3 or Rackspace cloud files makes this a whole heck of a lot more complex. Not to mention, if you wanted to add an author image here, you pretty much have to duplicate everything we just wrote. So what we're going to talk about next is how you can use carrierwave to replace this. But now that you have a good understanding of why this is important and how carrierwave works at the most basic level, you'll be able to actually use carrierwave pretty extensively, and it won't feel like random magic that someone put together for you.
Now that we've design our own mechanism for uploading and storing files on our server, let's take a look at how carrierwave does it. Now the one thing that I want to point out here is that carrierwave has a concept of an uploader. And an uploader is a ruby class that is defined, and it inherits from carrierwave's internal helpers. So it has a class that you basically you mount on your ActiveRecord model that says: Ok, any interaction with this cover attribute will be through carrierwave, so it's going to help you store the file weather that's on your local server or on Amazon s3 or Rackspace cloud, and it's also going to handle all the image processing that happens, and you can also do things such as configuring the storage directory where your files are saved. So this is what the uploader is designed for, it's to encapsulate all of the logic that happens inside of your application when an image is uploaded, and the reason why they do this is because like we talked about earlier, if you were to have an image for the book cover, as well as an image for the author, you might want to process those separately. So one of them might need to be a certain size, and the other one might need to be a different size. Now you can create two uploaders and separate all of that code out very cleanly in between the two. So to transfer over our custom file uploading system to carrierwave, we're going to first install the carrierwave gem, and that goes in our Gemfile, at the bottom, and we can run
bundle install, and we can restart our rails server, and then we can run the
rails generate uploader to generate a carrierwave uploader. I'm going to call this one cover so that it generates the cover uploader, and this will be what we use to handle cropping or whatever else we want to do with the cover images. So now that this is generated, let's take a look at what it does.
In here, we can see at the top there's a couple comments for plugins to carrierwave that you can install that allow you to do ImageMagick to do image cropping and scaling. So if you'd like, you can follow the carrierwave README and learn about how to install ImageMagick and enable these features. The next one is storage file which basically tells it: Save to the storage directory here that we've chosen. So this is very similar to how we layed out the folder structure for our book covers, what they do is they have the class name of the book first, then they have cover, which is what the uploader is mounted as, and then the model id. So that is how the file storage saves to a certain location, and then at the bottom you can override filename's and you can also enable a whitelist of extensions so that only jpgs or GIFs or pngs are allowed. And the option underneath storage file is called storage fog and fog is the rubygem that allows you to interact with remote file systems basically. So if you're going to use Amazon s3, Rackspace, cloudfiles, or you want to do something different, you can use fog to interact with those remote systems, and then when carrierwave recieves a file that's uploaded, it will go and save them remotely. So this is how carrierwave defines all of it's customizations for an upload, and you just simply configure it in here. There are only two more things we need to do to finish installing carrierwave, and that is to rename our column on our books table, and change cover file name to cover. And then we need to tell the books model that the cover database column is where we want to store the uploaded files.
rails g migration RenameCoverFilename
db/migrate/rename_cover_filename.rb
def change rename_column :books, cover_filename, cover end
rake db:migrate
app/models/book.rb
class Book < ActiveRecord::Base extend FriendlyId friendly_id :name, use: :slugged mount_uploader :cover, CoverUploader end
Anytime that a file is assigned to a cover attribute on a book, carrierwave will step in and handle it, and do everything that you've defined in the cover uploader. So with that, we can take a look at our rails application, it's uninitialized constant because we need to restart our rails application, and if we restart it now, everything is set up properly after we've installed carrierwave, and now we can come into our book, and we'll see that the image tag that we were using before no longer works, because we don't have the cover_filename attribute.
With carrierwave, the way to access the images, it's very simple and much cleaner than what we've wrote before. So here's what we've wrote before, and here's what we can do with carrierwave. So you can say
<%= image_tag @Book.cover.url %>
That's as simple as it is. They take the cover attribute and add some methods onto it to retrieve the URL for it, and we had to build the url ourselves. Now we could have spent a whole bunch of time moving this in to make this something compatible with carrierwave, but there isn't really much point in doing that when you can just use carrierwave.
The new image tag is working, but because we've uploaded the images to a different folder name, it's not available. So we're going to add the same thing here, and say
if Book.cover? and make it so that the image does not display if carrierwave doesn't see a cover. This is a little bit better, just because it's very clear if there's a book cover, so our code is really readable this way with carriere wave, and it makes a big difference as your application gets bigger. So we should be able to now go into "Edit" and we'll reupload the "Mastery" cover, and there we go. If we want to compare this to before, we can open the image in a new tab and take a look at the url, which is just about the same. It's now in an uploads/book/cover and then the database id, so ours was the database id first. It doesn't really matter either way, the way that I designed it, where you have the database id first means that all of the images for a single record are in the same folder which can be pretty convenient if you're going to do some manual work on like messing with images on the server. That is carrierwave, and I hope you learned quite a bit about file uploading, there's a whole ton to it, and I highly recommend checking out fog and playing with Amazon s3, because it's free for a year, and it's worth checking out.

The navigation that the application does to serve you a different view is called routing. Let’s get a solid understanding of routing in Angular.
Today we will be looking at one of the many interesting features of any frontend framework—routing—and how it is done in Angular.:
When building a single-page application (SPA) using Angular, you need to be able to ensure you take care of navigation and you can serve different views to your users as needed.
A great illustration is when you open any business website today, you will see the homepage, the Contact page, the About page and so on. If you proceed to click on the About page, you still see all the elements in the navigation, but the rest of the view changes to the About page. This same thing happens when you click the Contact page or any other page.
The navigation that the application does to serve you a different view is called routing.
Angular has a library package called the Angular Router (@angular/router) that takes care of routing in your Angular projects. If you set up the router and define routes, you can input a URL and Angular will navigate you to the corresponding view. You can click on a link or button and also get navigated, or you can also use the browser back and forward buttons to trigger router use.
Today we are building a simple navigation component to illustrate the concept of routing in Angular. We will be building this manually instead of using the Angular CLI so you can understand what goes into the work that the CLI does when you use it.
Create a new folder in the location of choice on your machine and open it with VS Code. Open the terminal and run the command below:
ng new router
When the Angular CLI prompt asks if you want to add routing, choose No and complete the setup for your project. Now let us install bootstrap so we do not have to style the Navbar component ourselves.
npm install bootstrap
After this, open your angular.json file and make sure the styles is defined like this:
“styles”: [ “node_modules/bootstrap/dist/css/bootstrap.min.css”, “src/styles.css” ]
Now we want to generate the
about and the
contact components.
ng generate component about ng generate component contact
You can see now files have been created and the app module file being updated. Inside the app component.html file, replace the content with the code block below:
>
This is a HTML list with three list items: Home, About and Contact. This is what we want to connect to the Angular Router so that we can serve different views for every new page we navigate to.
To display content from a child component, you have to tell Angular where exactly in the template you want the display to be. In the app component.html file, add these new lines:
> <app-about></app-about> <app-contact></app-contact> </div>
Now when you save your work, run the dev server and open the browser to localhost:4200. You should see this:
The routes are always defined in the app module. Open the app module file and replace the content with the code block below:
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { RouterModule, Routes } from '@angular/router'; import { AppComponent } from './app.component'; import { AboutComponent } from './about/about.component'; import { ContactComponent } from './contact/contact.component'; const routes: Routes = [ {path:'about', component: AboutComponent}, {path:'contact', component: ContactComponent} ]; @NgModule({ declarations: [ AppComponent, AboutComponent, ContactComponent ], imports: [ BrowserModule, RouterModule.forRoot(routes) ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }
Here we made three changes: first we imported the router module from Angular, then we created the routes in an array, and finally we declared it by adding it to the imports below.
This is how to set up routes in Angular. You can define navigations and all the views exactly how you want it here.
If you save your project at this stage, you will see that nothing has really changed in the views you serve. This because we still have app-about and app-contact displaying content from their parent component.
To change that, Angular provides the Router Outlet for use in the template. It basically tells Angular to check the routes defined and serve views just according to those definitions.
> <router-outlet></router-outlet> </div>
If you save the project, you will see that everything works as you would expect it to work.
This has been a quick introduction to routing in Angular. We have learned how important navigation is and how Angular handles it with routing. We saw how to set up routing from one component to another easily using the router module.. | https://www.telerik.com/blogs/angular-basics-beginner-guide-angular-router | CC-MAIN-2022-40 | refinedweb | 795 | 61.67 |
Hi,
First of all I apologies if I duplicate my post but I didn't see my mail
from yesterday pop out on the list. So here it is again :)
I am looking into implementing a system that would use as input a high
volume of apaches logs in order to produce reports used on a stats
website (table, graph...). The main requirement is to be low latency as
this is the reason we want to get rid of mysql currently not doing the
job properly.
This lead me to study various nosql databases, but Couch DB was the one
that caught my attention most. It's easy to setup and play with also the
incremental view seemed to really fit my needs. It allowed me to easily
import my existing data and start experimenting with views what leads me
here today. I am struggling to write a particular type of view and hope
I can find some guidance here...
To summarize here is what I am trying to achieve:
my database is filled with requests containing (among other things)
datetime and client_id. The view I'm trying to write should display the
number of occurrences for a date range grouped by client_id.
Unfortunately I don't manage to create a view that would contain the
expected result with the right format. The closest I could do was
producing a result as follow:
[2009, 11, 19, 61] => 14
[2009, 11, 20, 61] => 30
[2009, 11, 20, 64] => 30
...
This represents 14 occurences for the client 61 on the 2009-11-19, 30 on
the 2009-11-20 and so on. What I would like to retrieve is a resulted
grouped on client id to avoid having multiple rows for the same client
id)
The view is called with
startkey=[2011,11,1]&endkey=[2011,11,30,{}]&group=true&stale=ok
This is important for me because not being able to group mean I am
getting a "row" per day per client what leads to a response to big a
makes the latency to big on front.
Thanks,
Thomas | http://mail-archives.apache.org/mod_mbox/couchdb-user/201201.mbox/%3C1327047073.2079.1.camel@Thomas%3E | CC-MAIN-2014-42 | refinedweb | 348 | 71.18 |

I'm pretty new to Python, however I've been trying to write a script that first connects to server via SSH, then issues and command to read the contents of a file. <-- this works
My issue now is that I really don't want all of the contents of the file. I'd like to pass the output from the SSH command and then print out only lines matching particular search terms. I'm having a lot of trouble getting this to work and I'm sure this can't be that complicated.
All the examples I've found online pretty much involve a filename.txt to start with. However in my case I'm trying to read a file through SSH and then only display what I want. Hoping someone can provide me some sort of example on how I can achieve this.
I've included my code below with only the reading of the file part since nothing I was doing past that would work.
- Code: Select all
#!/usr/bin/python
import paramiko
import cmd
import re
import sys
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('HOSTIP', username='myusername', password='mypassword')
stdin, stdout, stderr = ssh.exec_command("cat /path/to/my/text/mytext.txt")
stdin.flush()
data = stdout.read()
print data
Hope someone can help!

Recently,. If I could pass these strings directly to SQL Server as part of a string query, this would be simple. I could just have:
sql = "SELECT * FROM Orders WHERE OrderDate BETWEEN '" + startdate + " ' AND '" + enddate + "'";
However, since the code was coming from a user, I did not want to do this because of SQL injections attacks, etc. As a result, I needed to create parameters for my query instead. In this particular case, I could not use a stored procedure so I used a parameterized query.
Below is the code I used to accomplish this. It also includes an example of how to use the version 3.0 of the Data Access Application Block, which allows for complete database independence (unlike version 2.0). If you have not checked that project out, it is very useful. You can reach it at:
I struggled for a while when I tried to figure out how to do a parameterized query using the Data Access Application Blocks so hopefully this code will serve as an example for that also. To do this, you first have to tack on 12:00AM to the start date and 11:59PM to the end date. This makes sure you get the entire day. If you are using stored procedures you can do this inside the procedure.
So here is the code:
using System;
using GotDotNet.ApplicationBlocks.Data;
using System.Data;
public class Converter {
public static void Main( string[] args ) {
if( args.Length != 2 ) {
Console.WriteLine( "Please supply a start and end date" );
return;
}
IDataReader rdr = GetTheDates( args[0], args[1] );
while( rdr.Read() ) {
Console.WriteLine( "OrderId: {0} - CustomerId: {1}", rdr[ "OrderId" ], rdr[ "CustomerId" ] );
}
}
public static IDataReader GetTheDates( string startdate, string enddate ) {
string dbcon = "Data Source=localhost; Integrated Security=SSPI;Initial Catalog=northwind";
SqlServer s = new SqlServer();
startdate += " 12:00AM";
enddate += " 11:59PM";
IDataParameter[] p = new IDataParameter[2];
p[0] = s.GetParameter( "@StartDate", DateTime.Parse( startdate ));
p[1] = s.GetParameter( "@EndDate", DateTime.Parse( enddate ));
string sql = "Select * From Orders WHERE OrderDate BETWEEN @StartDate AND @EndDate";
return s.ExecuteReader( dbcon, CommandType.Text, sql, p );
}
}
// COMPILE USING: csc string_datetime_convert.cs /r:GotDotNet.ApplicationBlocks.Data.dll
I hope this article was helpful. It is written for beginners in C# who are just learning how to connect to databases. Again, I would highly recommmend using the Data Access Application Block instead of the ADO.NET functions directly. The DAAB is very simple to use and reduces that amount of code drastically. This is my first article here so any suggestions about the content, formatting, would be. | https://www.codeproject.com/Articles/8321/Converting-Strings-to-DateTimes-for-Use-in-ADO-NET?fid=107636&df=90&mpp=10&sort=Position&spc=Relaxed&tid=932482 | CC-MAIN-2017-51 | refinedweb | 424 | 57.87 |

C++ Basic Syntax
When we consider a C++ program, it can be defined as a collection of objects that communicate via invoking each other's methods. Let us now briefly look into what a class, object, methods, and instant variables mean.
Object − Objects have states and behaviors. Example: A dog has states - color, name, breed as well as behaviors - wagging, barking, eating. An object is an instance of a class.
Class − A class can be defined as a template/blueprint that describes the behaviors/states that object of its type support..
C++ Program Structure
Let us look at a simple code that would print the words Hello World.Live Demo
#include <iostream> using namespace std; // main() is where program execution begins. int main() { cout << "Hello World"; // prints Hello World return 0; }
Let us look at the various parts of the above program − << "Hello World"; causes the message "Hello World" to be displayed on the screen.
The next line return 0; terminates main( )function and causes it to return the value 0 to the calling process.
Compile and Execute C++ Program
Let's look at how to save the file, compile and run the program. Please follow the steps given below − our 'Makefile Tutorial'.
Semicolons and Blocks in C++
In C++, the semicolon is a statement terminator. That is, each individual statement must be ended with a semicolon. It indicates the end of one logical entity.
For example, following are three different statements −
x = y; y = y + 1; add(x, y);
A block is a set of logically connected statements that are surrounded by opening and closing braces. For example −
{ cout << "Hello World"; // prints Hello World return 0; }
C++ does not recognize the end of the line as a terminator. For this reason, it does not matter where you put a statement in a line. For example −
x = y; y = y + 1; add(x, y);
is the same as
x = y; y = y + 1; add(x, y);
C++ −
All the compilers do not support trigraphs and they are not advised to be used because of their confusing nature.
Whitespace in C++
A line containing only whitespace, possibly with a comment, is known as a blank line,.
Statement 1
int age;
In the above statement there must be at least one whitespace character (usually a space) between int and age for the compiler to be able to distinguish them.
Statement 2
fruit = apples + oranges; // Get the total fruit
In the above statement 2, no whitespace characters are necessary between fruit and =, or between = and apples, although you are free to include some if you wish for readability purpose. | https://www.tutorialspoint.com/cplusplus/cpp_basic_syntax.htm | CC-MAIN-2019-09 | refinedweb | 436 | 68.6 |

Set the model that defines the nonlinear equations.
After the model is set, only the residual
f can change between solves and not the structure of the Jacobian
W. If a more significant change to
*model occurs, then this function must be called again to reset the model and reinitialize.
Get the model that defines the nonlinear equations.
Solve a set of nonlinear equations from a given starting point.
SolveStatusobject gives the status of the returned solution
*x.
Return if this solver object supports cloning or not.
The default implementation returns false.
Definition at line 201 of file Thyra_NonlinearSolverBase.hpp.
Clone the solver algorithm if supported.
Postconditions:
supportsCloning()==true]
returnVal != Teuchos::null
supportsCloning()==false]
returnVal == Teuchos::null
Note that cloning a nonlinear solver in this case does not imply that the Jacobian state will be copied as well, shallow or deep. Instead, here cloning means to just clone the solver algorithm and it will do a showllow of the model as well if a model is set. Since the model is stateless, this is okay. Therefore, do not assume that the state of
*returnValue is exactly the same as the state of
*this. You have been warned!
The default implementation returns
Teuchos::null which is consistent with the default implementation of
supportsCloning(). If this function is overridden in a base class to support cloning, then
supportsCloning() must be overridden to return
true.
Definition at line 208 of file Thyra_NonlinearSolverBase.hpp.
Return the current value of the solution
x as computed in the last
solve() operation if supported.
The default implementation returns
return.get()==NULL.
Definition at line 215 of file Thyra_NonlinearSolverBase.hpp.
Returns
true if
*get_W() is current with respect to
*get_current_x().
The default implementation returns
false.
Definition at line 221 of file Thyra_NonlinearSolverBase.hpp.
Get a nonconst RCP to the Jacobian if available.
forceUpToDate==true]
this->is_W_current() == true
Through this the RCP returned from this function, a client can change the
W object held internally. If the object gets changed the client should call
set_W_is_current(false).
The default implementation returns
return.get()==NULL.
Definition at line 228 of file Thyra_NonlinearSolverBase.hpp.
Get a const RCP to the Jacobian if available.
Through this interface the client should not change the object
W.
The default implementation returns
return.get()==NULL.
Definition at line 235 of file Thyra_NonlinearSolverBase.hpp.
Set if
*get_W() is current with respect to
*get_current_x().
Preconditions:
this->get_W().get()!=NULL
The default implementation throwns an exception.
