My intent is to use keyword argument defaults to make the dictionary an empty dictionary if it is not supplied.
>>> def f( i, d={}, x=3 ) :
... d[i] = i*i
... x += i
... return x, d
...
>>> f( 2 )
(5, {2: 4})
But when I next call f, I get:
>>> f(3)
(6, {2: 4, 3: 9})
It looks like the keyword argument d at the second call does not point to an empty dictionary, but rather to the dictionary as it was left at the end of the preceding call. The number x is reset to three on each call.
Now I can work around this, but I would like your help understanding this. I believed that keyword arguments are in the local scope of the function, and would be deleted once the function returned. (Excuse and correct my terminology if I am being imprecise.)
So the local value pointed to by the name d should be deleted, and on the next call, if I don't supply the keyword argument d, then d should be set to the default {}. But as you can see, d is being set to the dictionary that d pointed to in the preceding call.
What is going on?
Is the literal {} in the def line in the enclosing scope?
This behaviour is seen in 2.5, 2.6 and 3.1.
Thanks for your help!

I've gotten the capacity calculation working. And the path printout shows that a path between two points can also be found, but I can't get rid of edges resulting in dead-ends without breaking my code entirely. I've tried specifying bouncing back from dead-ends, but i hasn't worked so far. Any path using multiple-edged vertexes currently shows all of the edges connected to that vertex, whether or not that point is in the middle of the path or set as start/end. Basically, it covers all of the edges in-between the given points, even the superfluous ones.
My code so far is below. My attempts at removing the dead-end edges from the path are commented out, but still there.

Hello Everyone,
I've got a question about accomplishing something in regular expressions i.e is it possible and if so how.
Mind you regular expressions start to make my head spin after a while :-P
Short synopsis of what I am doing:
>I read Manga online (took Japanese in high school got addicted...)
>I like to open up the current issue in a new tab but I don't always remember to click the link with a middle click
>So I decided to write a Greasemonkey script that would run on any of the sites pages adding a target="_blank" to any anchor tag that references a manga or an issue of that manga so a regular click would open it in a new tab.
>The script itself is working fine nothing spectacular about it
Now on to I'll call it the caveat
>The link patterns we'll call it for each manga is as follows
<language of manga>/<manga name>
links to the main about page for the manga
<language of manga>/<manga name>/<issue number>
links to the issue number itself
<language of manga>/<manga name>/<issue number>/<page number>
links to the specific page of the issue
Now I want it to always make the first two open in a new tab but I do NOT want the last one to open in a new tab. The reason for this is when reading the actual manga each click to advance the page would open a new tab.
So to accomplish this I have two regular expressions
<!-- language: lang-js -->
var MangaIssueRegex = /en-manga\/[A-Za-z0-9\-]+\//;
var MangaIssuePageRegex = /en-manga\/[A-Za-z0-9\-]+\/(\d+\/){2}/
The first regex picks up any of the three manga link patterns.
The second regex picks up only the third manga link pattern (the one for a specific page)
In a nutshell the greasemonkey script loops through all the anchor tags on the page when it loads and if the href attribute of the anchor tag passes the MangaIssueRegex AND fails the MangaIssuePageRegex the anchor tag is modified to open in a new tab otherwise the anchor tag is not modified.
Now is it possible to combine both regular expressions into a single one that will match the first two patterns but fail if the third pattern is encountered?
If so please explain how I would really love to expand my knowledge about regular expressions even if it is just a little at a time.
Thanks in advance for the help everyone.
Going to include the whole script just because I know someone usually asks to see it to help them give good advice.
var MangaIssueRegex = /en-manga\/[A-Za-z0-9\-]+\//;
var MangaIssuePageRegex = /en-manga\/[A-Za-z0-9\-]+\/(\d+\/){2}/
var elements = document.getElementsByTagName("a");
for (var i = 0; i < elements.length; i++)
{
if (MangaIssueRegex.test(elements[i].getAttribute("href")) && !MangaIssuePageRegex.test(elements[i].getAttribute("href")))
{
elements[i].setAttribute("target","_blank");
elements[i].setAttribute("title","Opens in another tab");
}

I was going to suggest C# add the "throws" clause from Java, but after reading the Anders Hejlsberg interview (http://www.artima.com/intv/handcuffs.html) I see why it is not there.
Instead, I would like to suggest the **canthrow** statement. The **canthrow** statement would have the following properties
1. canthrow statement would be declared on the method and list the exceptions that this method throws.
2. canthrow would report to the calling methods or intellisense the exceptions that can be thrown, as well as any exceptions that a called method could throw and are not handled locally.
3. canthrow is **not** contractual, so versioning is not a problem.
The idea here is that most developers want to catch and handle the proper exceptions, but they simply don't know what they are. If we have a way to inspect the methods a design time, developers will be more likely to add and handle the exceptions that are relevant and let the unhandled exceptions bubble up.
Now as final thought, you probably can say that this could all be done by Intellisense using reflection, but that would return every and all exception possible. The canthrow would be allow the library developer to emphasize the exceptions that are expected to be handled by the callers.
What do you think?

I have a python program which acts as a client (and does several other things as well). Currently, I have to start the server first by opening a command/terminal window and typing:
cd [path to directory containing rajant_server.py
jython rajant_server.py
Once the server successfully connects it waits for the client, which I start by running:
cd [path to directory containing python client program]
python main.py
When the client connects, the server prints out information (currently for debug) in it's command/terminal window, and the client program prints out debug information in it's command/terminal window. **What I want to do is do away with the complex process by calling jython from my 'main.py' program using the subprocess module.**
The problem is two fold:
1 - I need the rajant_server.py program to open in it's own terminal/command window
2 - jython needs to be run in the directory where the rajant_server.py file is stored, in other words, typing the following into the command/Terminal Window doesn't work (don't ask me why):
jython C:/code_dir/comm/server/rajant_server.py
but:
cd C:/code_dir/comm/server
jython rajant_server.py
does work.

Okay... I just got something to work. It seems like a bit of a hack, so I would still love ideas on a better approach. Here is what I am currently doing:
serverfile = r'rajant_server_v2.py'
serverpath = os.path.join(os.path.realpath('.'),'Comm',serverfile)
serverpath = os.path.normpath(serverpath)
[path,file] = os.path.split(serverpath)
command = '/C jython '+file+'\n'
savedir = os.getcwd()
os.chdir(path)
rajantserver = subprocess.Popen(["cmd",command],\
creationflags = subprocess.CREATE_NEW_CONSOLE)
#Change Directory back
os.chdir(savedir)
#Start Client
rajant = rajant_comm.rajant_comm()
rajant.start()
If you have a solution that will work in both linux & windows you would be my hero. For some reason I couldn't change the stdin or stdout specifications on the subprocess when I added creationflags = subprocess.CREATE_NEW_CONSOLE. | python | subprocess | jython | null | null | null | open | Starting jython program from python using subprocess module?

When the client connects, the server prints out information (currently for debug) in it's command/terminal window, and the client program prints out debug information in it's command/terminal window. **What I want to do is do away with the complex process by calling jython from my 'main.py' program using the subprocess module.**
The problem is two fold:
1 - I need the rajant_server.py program to open in it's own terminal/command window
2 - jython needs to be run in the directory where the rajant_server.py file is stored, in other words, typing the following into the command/Terminal Window doesn't work (don't ask me why):
jython C:/code_dir/comm/server/rajant_server.py
but:
cd C:/code_dir/comm/server
jython rajant_server.py
does work.
---
Okay... I just got something to work. It seems like a bit of a hack, so I would still love ideas on a better approach. Here is what I am currently doing:
serverfile = r'rajant_server_v2.py'
serverpath = os.path.join(os.path.realpath('.'),'Comm',serverfile)
serverpath = os.path.normpath(serverpath)
[path,file] = os.path.split(serverpath)
command = '/C jython '+file+'\n'
savedir = os.getcwd()
os.chdir(path)
rajantserver = subprocess.Popen(["cmd",command],\
creationflags = subprocess.CREATE_NEW_CONSOLE)
#Change Directory back
os.chdir(savedir)
#Start Client
rajant = rajant_comm.rajant_comm()
rajant.start()
If you have a solution that will work in both linux & windows you would be my hero. For some reason I couldn't change the stdin or stdout specifications on the subprocess when I added creationflags = subprocess.CREATE_NEW_CONSOLE. | 0 |

So I have a class Coord which contains a float x and a foat y.
The constructor is :
void Coord::Coord (float x,float y)
{
this->x = x;
this->y = y;
}
I create all the points that I need in that way :
Coord pt1(0,1);
Coord pt2(20,0);
...
Coord pt61(12,14); .... `
After I have to make an array of some points , for exemple
the fifth five points will be assignated in an array, 4 other points in an other array, 2 other points in another one...
Coord pts_weakhealth[3] = {pt1,pt2,pt3};
This array, i'll have to give as arguments for the constructor of a class
for exemple :
Sef health(pts_weakhealth,3);
Sef strenght(pts_weak,4);`
I'll create some Sef in the same way and then make an array of them
Sef spec[2] = {health,strenght};
and a class universe will contains some sef :
Universe hlth(spec);
You can imagine that when i have a lot of points, a lot of sef, it's a lot of dirty code...
How can I improve that? to make my code better....
Thanks !!!

I'd like to have the images 'repeat' as the slideshow ends. So the user scrolls through the slideshow, it reaches the end of the image LI's and then seamlessly repeats from the start.
Here's the current code:
<b>jQuery</b>
$(document).ready(function()
{
$('#products ul').css('width', ($('#products ul li').length * 185));
var $products = $('#products div');
var posLeft = 0;
// Add 5 DIV overlays to use as 'hover buttons' for the slideshow speed
for (i = 0; i <= 4; i++)
{
$('#products').append('<div class="hover-' + i + '" style="background: transparent; width: 100px; height: 167px; position: absolute; left: ' + posLeft + 'px; top: 15px;"></div>');
posLeft += 100;
}
// Function animate the scrolling DIV in the appropriate direction with the set speed
function plz2scroll(direction, scrollSpeed)
{
var scrollDir = (direction == 'left') ? '-=' : '+=';
var scrollOffset = (direction == 'right') ? '-10' : '+' + $products.css('width').substring(0, -2) + 10; // Fix the '+100px10' issue - Seems substring don't support negative offsets
$products.animate({scrollLeft: scrollDir + $products.css('width')}, scrollSpeed, 'linear', function()
{
$products.scrollLeft(scrollOffset);
plz2scroll(direction, scrollSpeed);
});
}
// Create the 'hover buttons'
$('div.hover-0').hover(function() { $products.stop(); plz2scroll('right', 2000); });
$('div.hover-1').hover(function() { $products.stop(); plz2scroll('right', 3500); });
$('div.hover-2').hover(function() { $products.stop(); });
$('div.hover-3').hover(function() { $products.stop(); plz2scroll('left', 3500); });
$('div.hover-4').hover(function() { $products.stop(); plz2scroll('left', 2000); });
});
<b>HTML</b>

<li><img src="images/4.jpg" /></li>
<li><img src="images/5.jpg" /></li>
</ul>

The scroller works and the speed/direction works nicely with the overlayed DIV buttons. My animate() callback to repeat is slow, buggy and just bad :/
My overuse of .stop() also looks like a potential problem >.<

If I find the item I am searchin for in any of the leg, I wish to stop searching further for that root.
I can return a value from the call-template, but do not know how to implement it and put it as a parameter further. The parameter `Found` in the template will play otherwise. If I can update the value of the parameter from the earlier recursion, it will help me. But how can I do it?

I had some Javaexperience before (JDK1.4->7). In my app I want to ask for a password, so curious people will not see the images that the app displays in three activities. Of course I am asking for the password when the main activity is started (with a intent in onCreate()). But I want to be shure that the App will ask for the password again after inactivity (e.g. device lying around, screensaver on and someone picks up the phone (and the phone has no pin or other protection)). Another situation where I want to ask for the password is when I start another activity. When someone then presses the Homebutton, gets the last tasks and selects my App, and this is not destroyed until then, and comes back from the stack. In this case a password should be required. Important is, that I dont want to have password questions during normal use of my app.
I studied Q&A at SO and the guides on lifecycles and did some testing but no matter where I exactly place a call to the password activity, it always happened that it it will (randomly) appear in situations I don't wanted it to appear (orientation changes, between a normal-use-switch between activities etc.), or that it does not appear when I want it to appear. I guess it is not done with placing the check/call to the password activity in the right method of the lifecycle of an app. There must be a way to check for especially the circumstances described above? So what do you think is the best place for this check, and what system values should be inspected? | android | passwords | lifecycle | null | null | 07/19/2012 12:38:02 | not a real question | Android Lifecycle and Password Activity

In a for loop why doesn't a compiler determine the number of times it has to run based on the initializer, condition and increment and then run the loop for the predetermined number of times??
Even the advanced for in Java and the for in python which allow us to iterate over collections would act funny if we modified the collection.
If we do want to change the iterating variable or the object we are iterating upon, we might as well use a while loop instead of a for. Are there any advantages to using a for loop in such a case??
Since no language does a for loop the way I have described, there must be a lot of things I haven't thought about. Please point out the same.

I'm looking for a way to write tests for this application. Ideally, I'd like for these tests to bring up their own mail server, push my test emails to a folder on this mail server, and have my application scrape the mail out of the mail server that my test started.
Configuring the application to use the mailserver is not difficult, but I do not know where to look for a programatic way of starting a mail server in Java. I've looked at JAMES, but I am unable to figure out how to start the server from within my test.
So the question is this: What can I use for a mail server in Java that I can configure and start entirely within Java? | java | email | testing | mail-server | null | null | open | Working with a Java Mail Server for Testing

if (x < y) return -1
else if (x > y) return 1
else return 0
or
return ((x > y) ? 1 : ((x < y)) ? -1 : 0))
Two comparisons for what seems can be accomplished with only one. In assembly all you have to do is subtract both to a register, check if is negative, check if is zero. The problem is in javascript if we were to subtract:
var sub = (x - y);
return (sub == 0 ? 0 : ((sub < 0) ? -1 : 1))
This would end up with even more code to be executed.
So, some questions:
- Is there a way of simplifying or speedying this in javascript?
- Can compiled javascript interpretors like chrome's optimize this kind of comparison?
