I'm working on a C++ programming exercise from a text book but could not figure out how to get it working. Hope if anyone could point out the error in my code. Here comes the problem...
"Use an istream_iterator, the copy algorithm and a back_inserter to read the contents of a text file that contains int values separated by whitespace. Place the int values into a vector of ints. The first argument to the copy algorithm should be the istream_iterator object that's associated with the text file's ifstream object. The second argument should be an istream_iterator object that's initialized using the class template istream_iterator's default constructor - the resulting object can be used as an "end" iterator. After reading the file's contents, display the contents of the resulting vector."
I built following code. The code compiles, but does not do anything.
int main()
{
std<IP_ADDRESS>vector< int > testVector;
std<IP_ADDRESS>ifstream inputFile( "/Users/GrinNare/Documents/Study/C++/Chapter 16/Chapter 16/16_10_Text_File.txt", std<IP_ADDRESS>ios<IP_ADDRESS>in );
std<IP_ADDRESS>istream_iterator< int > inputFromFile( inputFile );
std<IP_ADDRESS>copy( inputFromFile, std<IP_ADDRESS>istream_iterator< int >(), back_inserter( testVector ) );
for ( int i = 0; i < testVector.size(); i++ )
std<IP_ADDRESS>cout << testVector[i] << "\t";
std<IP_ADDRESS>cout << std<IP_ADDRESS>endl;
return 0;
}
Text file contains the following:
"12 23 43 34"
I tried to debug the code and noticed that values in the text file are not read properly into int vector because they are separated by whitespace, not new line.
Could anyone please help?!

Say, I have Parent class with private method method1. Then there's a class Child that extends Parent class. Child also defines method called method1, but it is public. Please see below for example:
public class Main {
public static void main(String[] args) {
Parent p = new Child();
p.method2();
}
}
class Parent{
private void method1() {
System.out.println ( "Parent's method1()" );
}
public void method2() {
System.out.println ( "Parent's method2()" );
method1();
}
}
class Child extends Parent {
public void method1() {
System.out.println ( "Child's method1()" );
}
}
What I don't understand is that the output is below!!!
Parent's method2()
Parent's method1()
I know that since method1 is private in Parent, method1 in Child has nothing to do with that of Parent. If so, then when method2 invokes method1, why is Parent's method1 is called not Child's? Especially when the actual type is Child.
It seems like there's absolutely no clue which method1 is called from method2.
Am I missing a inheritance rule? Please please help!!!

I have written functions to Save, Manage(delete, rename) and select Variants from the drop down. However i see strange behavior when i select a variant in the method mentioned below.
onSelectVariant: function (oEvent) {
var sSelectedVariantKey = oEvent.getParameter('key');
Assume i have existing variants 'A1', 'A2' and 'A3'.
When i SaveAs a new variant with new values (lets call it 'X1'), the new variant is created. Then i select another already existing variant from dropdown( A1 or A2 or A3), i see the corresponding values. Now i again select the newly created variant X1 but i don't see the new values.
When i debug the above mentioned method, i see that for all the existing variants, the oEvent.getParameter('key') returns the variant indexs like 0,1,2,3 etc. but for the newly created variant X1, it returns the value 'sv1579082806311' and hence it doens't find it in variantset
oPersonalizationVariantSet.getVariant(sVariantKey)
and then it doesn't show the new values.
If i run the program again, i see that previously created variant X1 now shows correct values as the method oEvent.getParameter('key') returns the index and not 'sv....'. but if i now create a new variant X2, the same issue happens with X2.
I am running the App on cloud WebIDE and not on the FIORI launchpad.
Can someone help me what may be going wrong while saving the variant ?
Thanks

The original string of characters is uploaded as a file, and the return for the encode method is a new file containing the translation table and the encoded message, in order.
Here is an example of what an output file would contain.
{0=0100, 1=0111, 2=11, 3=00, 4=10, 5=0110,
=0101}
0110101100111101110100011100111000100011001011100101
My encode method:
Map<Character, Integer> freq = new HashMap<>(); //store char, freq in map
for (char c: message.toCharArray()) { //thank you enhanced for loop
freq.put(c, freq.getOrDefault(c, 0) + 1);
}
//queue stores nodes
PriorityQueue<Node> pq;
pq = new PriorityQueue<>(Comparator.comparingInt(l -> l.freq));
//nodes will be sorted by comparator
//using hashmap we add the nodes to the queue
for (var entry : freq.entrySet()) {
pq.add(new Node(entry.getKey(), entry.getValue()));
}
while (pq.size() != 1) //must be more than 1 node
{
//removes the two nodes of lowest freq
Node left = pq.poll();
Node right = pq.poll();
//connect new nodes
int sum = left.freq + right.freq; //summary of freq, for parent
pq.add(new Node('\0', sum, left, right)); //add back
}
//root of tree
Node root = pq.peek();
//new map for huffman codes
Map<Character, String> huffmanCode = new HashMap<>();
coding(root, "", huffmanCode);
//testing
//print the <PERSON> codes so we can know them (move this later)
//System.out.println("Huffman code is " + huffmanCode);
//testing
//print encoded message
StringBuilder sb = new StringBuilder();
for (char c: message.toCharArray()) {
sb.append(huffmanCode.get(c));
}
//System.out.println("Encoded string is : " + sb); //check file format
Pair<Map,StringBuilder> p = new Pair<Map,StringBuilder>(huffmanCode,sb);
return p;
I convert the pair into a string in the main method.
In order to decode this string, I am supposed to re-upload the file and use the information it contains to create a new file with the original uncoded message. I would have no problem decoding the message if it weren't for the uploading requirement. I lose access to the huffman tree I previously encoded and I have been unable to preserve it in the output files as I am required to only return strings.
I have tried splitting strings and working backwards from the table, but without the tree I am really struggling to decode the string without the huffman tree. Is there any way to preserve the tree in the output file, or is there a way to reconstruct the tree using the translation table? Thanks.

public class RegularStuff {
public int getAmountOfStuff() {

}
public int getAmount() {

}
@Test
public void testGetAmountOfStuff() {

}
Note that the above assertion is invalid. It will fail because the method getAmountOfStuff calls another method that always returns 10. I split these up to make the code simpler to analyze. It might seem trivial given this example, but I often find myself creating much larger methods. Thus, I split up code in a given function. Otherwise the sheer amount of text becomes too big/confusing to analyze or fix- let alone test.
So what I need to know is how to control the output of certain methods in the class I'm testing.

}
Both cg and cargo are getting their data from an external json object. It's worth noting that while they have the same exact data and structure, cg and cargo are separate arrays. This is so that selecting an item from the select dropdown doesn't cause the others to disappear.
After a lot of trial and error, I got the code to work. However, I want each item of the select tag to show both the cargo's category, and its given name. Any help would be greatly appreciated.

г) выражены двумя вопросительными, или двумя восклицательными, или двумя побудительными предложениями, например: Неужели впереди болото и путь к отступлению отрезан? Как часто мы встречались вместе и какие вели интересные беседы! (Фурманов);
Также, в старом издании, Параграф 30, пункты 3.2 и 3.3:
Запятая перед соединительным и разделительным союзами в сложносочиненном предложении не ставится, если в его состав в качестве частей входят:
...
2) побудительные предложения: Подпустить врага и огонь дать по команде! (Фурманов) — объединяет побудительная интонация; Пусть кончится холод и наступит тепло! — объединяет побудительная частица; Да будет свято имя героя и память о нём сохранится в веках! — объединяет побудительная частица;
3) восклицательные предложения: Как он смешон и как глупы его выходки! — объединяет восклицательная интонация; Как часто мы собирались вместе и какие вели интересные беседы!; Сколько скрытого смысла в этих словах и какой отклик вызывают они у слушателей!
Приведенные примеры без запятой, на мой взгляд, четко соответствуют 2г (побудительная форма).
Приведенные пример с запятой нарушают приведенное правило. Возможно, просто потому что нарушают. Возможно, потому что автор не вкладывал должной "побудительности" (простите за выражение) или восклицательной интонации. Как минимум, ни в одном из примеров с запятой нет восклицательного знака.

<select id="county_id" name="county_id" multiple="" tabindex="-1" class="select2-hidden-accessible" aria-hidden="true">
<option value="" selected="selected"></option>
<option value="1">Adams</option>
<option value="2">Ashland</option>
<option value="3">Barron</option>
But when I select an item in the list, a blank box (the first, blank option) is shown as the first selection, right before the item I've selected. Note the first list item below:
<span class="select2-selection select2-selection--multiple" role="combobox" aria-autocomplete="list" aria-haspopup="true" aria-expanded="false" tabindex="0">
<ul class="select2-selection__rendered">
<span class="select2-selection__clear">×</span>

<li class="select2-selection__choice" title="Kenosha"><span class="select2-selection__choice__remove" role="presentation">×</span>Kenosha</li>
If I don't prepend the list with the blank option, then the placeholder does not work and the first list item is selected by default.
The closest example on the select2 site uses option groups (my list does not), and does not appear to have a blank option. I don't recall running into this issue with v3.5x. I don't have any options set except placeholder. What could I be doing wrong? How can I get rid of this extra blank selection?

I'll leave it to you to figure out how to match these values with your backend data.
Checkboxes are not so good for this scenario; the user could leave them both blank, and you don't get your answer. If you are asking a yes/no or true/false question where you want only one answer, then you should be using radio buttons instead of checkboxes.

When I tap on an input field on my test device (nexus 5), the soft keyboard opens and the view becomes scrollable, as expected.
However, the page view shinks and some of my content is left floating on whitespace if you scroll the view up (see link below) (grey is the background image im testing with, it is shrunk by about 40% when the keyboard opens)

I spun up a tutorial version of JQuery mobile and they do not have this issue. The page loads and scrolls in full and I believe they are using some JS to hard set the height of the main element or something to that matter.
Is there a way of solving this white space issue without using an existing framework as I'd rather not want to have to hard override the JQuery mobile CSS

Usually, this is an indication of some design problem, either with the code we're testing or with tests themselves.
While it sounds like using a truncation strategy has fixed this particular problem (see more on that below), i would suggest that there is more to learn from the situation.
Consider the two examples from your spec above. The only difference between them comes down to whether the code parameter is valid or not. I would argue that these examples are really testing the Group model, not the controller.
Now, if we're confident in our model test coverage, then we can take a different approach to the controller spec. From the controller's perspective, the model is a collaborator and in general, we always want to avoid indirectly testing collaborators. In this case, we can use a mock to simulate the behavior of the Group model and only test the controller behavior in isolation.
Something like this (please note the code below is incomplete and untested):
# spec/controllers/groups_controller_spec.rb
describe "#create" do
before do
# use a Test Double instead of a real model
@new_group = double(Group)
@params = { :cdb_group => 'stub_cdb_group_param', :service_id => service }
# using should_receive ensures the controller calls new correctly
Group.should_receive(:new).with(@params[:cdb_group]).and_return(@new_group)
end
context "when cancelled responding to js" do
it "renders hide_new" do
post :create, @params.merge({:button => "cancel", :format => "js"})
expect(response).to render_template('hide_new')
end
end
context "with valid params" do
before do
@new_group.should_receive(:save).and_return(true)
end
context "responding to json" # ...
context "responding to html" # ...
context "responding to xml" #...
end
context "with invalid params" do
before do
@new_group.should_receive(:save).and_return(false)
end
# ...
end
end
While the above doesn't specifically address the problem with record counts you were having, i suspect the problem may go away once you isolate your test targets correctly.
If you choose to stick with database truncation, consider using it selectively as described here.
I hope at least some of that helps :).

Here's one way using a forked process and a pipe:
# When given '-' as the first param, IO#popen forks a new ruby interpreter.
# Both parent and child processes continue after the return to the #popen
# call which returns an IO object to the parent process and nil to the child.
pipe = IO.popen('-', 'w+')
if pipe
# in the parent process
%w(please upcase these words).each do |s|
STDERR.puts "sending: #{s}"
pipe.puts s # pipe communicates with the child process
STDERR.puts "received: #{pipe.gets}"
end
pipe.puts '!quit' # a custom signal to end the child process
else
# in the child process
until (str = gets.chomp) == '!quit'
# std in/out here are connected to the parent's pipe
puts str.upcase
end
end
Some documentation for IO#popen here. Note that this may not work on all platforms.
Other possible ways to approach this include Named Pipes, drb, and message queues.

I have several ideas regarding possible approaches, however, I would like your advice on how could I do that as fast as possible.
Please also consider the following:
1) Part of the UUID (6 last Bytes) is common to all Beacons (so maybe I should avoid comparing that part)
2) I do not mind if your recommendation demands having stored my Beacons in a specific way (to fasten the comparisons).
PS. I was thinking of getting a byte array of the first 10 bytes and trying to convert them into a long and search for that as a key within my Beacon's HashMap. Dunno

libjson-c.so.3 => /lib/x86_64-linux-gnu/libjson-c.so.3 (0x00007ff16a88c000)
And following in Ubuntu 14.04 -
libjson-c.so.2 => /lib/x86_64-linux-gnu/libjson-c.so.2 (0x00007f0848838000)
I guess something wrong with JSON-C versions. I couldn't found any useful information on google. Any ideas what sort of problem this is?

Forward packets between SR-IOV Virtual Function (VF) NICs
Basically what I want to do is use 4 SR-IOV functions of Intel 82599ES and direct traffic between VFs as I need. The setup is something like this (don't mind the X710, I use 82599ES now)
For the sake of simplicity at testing I'm only using one VM running warp17 to generate traffic, send it though VF1 and receive it back from VF3. Since the new dpdk versions have a switching function as described in https://doc.dpdk.org/guides-18.11/prog_guide/switch_representation.html?highlight=switch
, I'm trying to use 'testpmd' to configure switching. But it seems to be test pmd doesn't work with any flow commands I enter. All I get is "Bad argument". For example it doesn't work with this command,
flow create 1 ingress pattern / end actions port_id id 3 / end
My procedure is like this,
Bind my PF(82599ES) with igb_uio driver
Create 4 VFs using following command,
echo "4" | sudo tee /sys/bus/pci/devices/0000:65:00.0/max_vfs
Bind 2 VFs to vfio_pci driver using,
echo "8086 10ed" | sudo tee /sys/bus/pci/drivers/vfio-pci/new_id
sudo ./usertools/dpdk-devbind.py -b vfio-pci 0000:65:10.0 0000:65:10.2
Use PCI passthough to bind VFs to VM and start the VM
sudo qemu-system-x86_64 -enable-kvm -cpu host -smp 4 -hda WARP17-disk1.qcow2 -m 6144 \
-display vnc=:0 -redir tcp:<IP_ADDRESS>22
-net nic,model=e1000 -net user,name=mynet0
-device pci-assign,romfile=,host=0000:65:10.0
-device pci-assign,romfile=,host=0000:65:10.2
Run testpmd with PF and 2 port representators of VFs
sudo ./testpmd --lcores 1,2 -n 4 -w 65:00.0,representor=0-1 --socket-mem 1024 --socket-mem 1024--proc-type auto --file-prefix testpmd-pf -- -i --port-topology=chained
Am I doing something wrong or is this the nature of testpmd?
My dpdk version is 18.11.9

0..4=LOW (0)
5..9=HIGH (1)
I start calculating π using chudnovski algorithm... and so i start π=3.1415.... (π=0.0001....)
At the same time as I calculate the infinite tail of π, I compare the data that I wish to send to somebody else, until I find a 100% match of length.
So after I find a match, I am telling my remote friend "the data that I wish to send you starts at the 9.876.543 digit of pi and its size is 1MB after the starting point. Convert it accordingly (0-4=0; 5-9=1;)
This way you could transmit data just by providing starting point and size.
Also , there will be thousands of ways to optimise the algorithm.
Inside the π lies ANYTHING ! From my dna to the farest multiverse.

If we take into account the dependency inversion principle (In SOLID principles), then we should always aim for our classes to depend on abstractions and not on implementations.
However we could also take into account the "KISS" principle (Keep it stupidly simple) and in this way I could tell you that if your application is not very large or complex, then do not use an interface.
Answering your question: "what is better to use interface with one implementation and inject interface or just create a class without interface and inject class?"
I recommend using an interface even if it has only one implementation, so in the future if the implementation changes, the class that depends on said interface will not be affected by said change, unless the interface signature changes as well.

foo1

I changed it to tar cvf /dev/st0 foo* | xargs ls -lah > backup.log

Any type of real-space ranging and detection systems are going to use electromagnetic carrier waves, which can't exceed the speed of light. If the fleets are at such vast distances from each other, the target will have moved a significant distance before your phaser fire can reach it. All your shots will therefore miss. The ships will have to be quite close before opening fire, to overcome this drawback. |

I ended up changing it to an implementation that uses numpy.select, which is computing every function over the entire time window instead of just the region where its condition is active. It seems inefficient, but I suppose the alternative is to write a custom autograd primitive...

new_one = Article(**payload.article)
tags = []
for tag_name in payload.tags:
tag = session.query(Tag).filter_by(name=tag_name).first()
# tag will be None if it does not exist in the database
tags.append(tag if tag else Tag(name=tag_name))
new_one.tags = tags
sesion.add(new_one)
session.flush()
So now you'll be using the existing tag if it's already in the database or create a new one if it's not.

Hello currently I am working on android and I am stuck to implement the structure picture above.
I need to add and delete the CardView in the list.
I have tried it with RecyclerView and also used NestedScrollView to avoid double scroll, but I
faced a problem that the animation is not available anymore when deletion because when
deleting an item, the size of the recyclerView is forcibly reduced by NestedScrollView, so the
animation cannot be operated normally.
So what I want to know is if there is any way to implement it without NestedScrollView
If not, how can I restore the animation working?

HiveMetastoreBridge code
Why are we clearing relationships in findEntity method?
What does add referred entity does exactly in the background ? To be clear in toTableEntity method we are adding ObjectId of related entites as attributes as well calling addReferredEntity method of AtlasEntity.
In registerInstance method why are we creating references from first entity to other referred entities in else if statement. When will multiple entities be created and why will the first have reference to others?
In importTable method why after creating AtlasEntity processInst we are again creating AtlasEntitiesWithExtInfo createTableProcess and adding process entity and path entity to it? Why not Table entity too?

It states that
You are given a permutation of n numbers that are between 1 to n and having no duplicates.
Task is to sort that permutation in ascending order.There is another array Q in which we are inserting elements from given permutation P.
You have to implement N steps to sort P. In the i-th step, P has N-i+1 remaining elements, Q has i-1 elements and you have to choose some x-th element (from the N-i+1 available elements) of P and put it to the left or to the right of Q. The cost of this step is equal to x * i. The total cost is the sum of costs of individual steps. After N steps, Q must be an ascending sequence. Your task is to minimize the total cost.
Input
The first line of the input file is T (T ≤ 10), the number of test cases. Then descriptions of T test cases follow. The description of each test case consists of two lines. The first line contains a single integer N (1 ≤ N ≤ 1000). The second line contains N distinct integers from the set {1, 2, .., N}, the N-element permutation P.
Output
For each test case your program should write one line, containing a single integer - the minimum total cost of sorting.
Now i have figured out the dp
My recurrence relation states that for getting most optimal values from elements having value i to j i will have to insert either $i$ at front or $j$ at back.
Cost of inserting i at front = dp[i+1][j]+cost of adding element i at front
Cost of inserting j at back = dp[i][j-1] +cost of adding element j at back
and i have to take minimum of these.answer would be dp[1][n]
for(l=1;l<=n;l++) //length of current permutation Q
{
for(i=1;i<=n-l+1;i++) //starting value of permutation Q
{
j=i+l-1; //ending value of permutation Q
dp[i][j]=min(dp[i+1][j]+l*xi,dp[i][j-1]+l*xj);//chosing wether to insert i at start or j at end
}
}
here xi=index of element i from start of permutation P.
and yi=index of element j from start of permutation P.
ans would be dp[1][n]
But am unable to figure out xi and xj
Please help

self.check_box2.stateChanged.connect(self.onStateChange)
Therefore the event onStateChange is triggered twice when you check check_box2, which is logical.
I think you did a copy paste and the last should be check_box3. But your naming conventions are not intuitive, give your objects some more meaningful names, otherwise how are you going to tell the difference from your code.
If what you want is mutually exclusive checkboxes the implementation could be more straightforward. Personally I prefer to use radio buttons like in plain HTML because this is more intuitive (it is immediately obvious that only one answer is allowed).
First approach: a generic method that loops on the checkboxes in your form and unchecks all of them except the sender. Then you can simplify code and get rid of if/elif
Second approach: use QT built-in features. You could wrap your checkboxes in a QButtonGroup container.
A rectangular box before the text label appears when a QCheckBox
object is added to the parent window. Just as QRadioButton, it is also
a selectable button. Its common use is in a scenario when the user is
asked to choose one or more of the available options.
Unlike Radio buttons, check boxes are not mutually exclusive by
default. In order to restrict the choice to one of the available
items, the check boxes must be added to QButtonGroup.
and:
As mentioned earlier, checkBox buttons can be made mutually exclusive
by adding them in the QButtonGroup object.
self.bg = QButtonGroup()
self.bg.addButton(self.b1,1)
self.bg.addButton(self.b2,2)
QButtonGroup object, provides abstract container for buttons and
doesn’t have a visual representation. It emits buttonCliked() signal
and sends Button object’s reference to the slot function btngroup().

I was thinking about **null byte injection**. I am not sure that the `empty` function will always be safe enough. If you provide a null character it seems to return false. POC: `` Output: `bool(false)`. There are quite a few pitfalls with this function, `0` or `'0'` will also return true which is probably not what the coder had in mind in and may cause problems in some edge cases.

It’s theoretically possible (from a conceptual point of view) to split that process in N chunks and execute them in parallel, as long as the output of all parallel jobs can be collected and joined together before sending it back to the client that initiated the process. I’d like to use this parallelization to optimize performance.
How can I implement this parallelization with EJBs? I know that we should not create threads in a EJB method. Instead, we should publish messages (one per job) to be consumed by message driven beans (MDBs). But then it would not be a synchronous call anymore. And being synchronous seems to be a requirement in this case since I need to collect the output of all jobs before sending it back to the client.
Is there a solution for this?

The historical evidence shows that throughout medieval times, knights and men-at-arms wearing mail and/or plate armor were killed in large numbers by archers with longbows | 71638cfd9623eadb7d3bf78ae90d80f3901a71306231c30f8f49783a8ae638e2 | ['ad176a8b2d5c452d8af0a3f7f3bfe659'] | That is a good point. A whole diocese could almost go under because the local bishop's blessed water "doesn't, uhm.. work anymore." It wouldn't be quite the same as in the Middle Ages until the world had a good handle on the Vamp problem. The government would have a hard time appointing its own favorite, corrupt bishops too. It could be very chaotic for the Church too as things could change very rapidly. An interesting though: Someone could attempt to remove a good bishop by replacing the water he blessed (which is then distributed to the diocese) with regular water.. |

So there are really two questions here:
(1) How do I most easily save all existing SO favorites to Evernote? (this is perhaps the trickier of the two)
(2) Is there a clean way to automatically save new SO favorites to Evernote (IFTTT style), or would it be easiest to simple favorite the item AND webclip it each time (not ideal but one potential solution that comes to mind).
Would love to hear your input.

That's not the whole schematic, just the regulator section. The plot thickens.. it appears that the additional current is further down the line somewhere, but only when this regulator is used. The only other significant component I have down the line is a CP2102. RDTSC - Scoping the power lines doesn't show anything unruly. I wonder if the CP2102 isn't going into suspend properly. | 913edb657c1680ac29a9f24b232447278fa7123b496a2b416f1f0855aa7cce3c | ['ad3810e72c694c1f9239934ca243cb42'] | <PERSON> I don't but it's very similar to a 540; it's in a small submersible motorhome water pump. The problem appears to be with a few different pumps of a similar size. I would have thought a large starting current would be worse when I hard-started the motor rather than soft start with a voltage ramp? |

Spring provides wrapper around standard specifications in JAVA like JTA, JDO, JDBC, etc. Whereas JCo is just a connector API provided by SAP to transact with SAP internal objects and interfaces. Currently, to my knowledge Spring does not provide any support for JCo.
JCo3 supports JCoContext for stateful connections, which is of little help but not to the extent what you may need.
You may actually need to implement JCoServerTIDHandler and one more interface from the same package (I don't exactly remember) for effective control over transaction management. Eventually, it will mean implementing Java Connector Architecture (JCA). This will be the right solution for your problem.
Hope, this helps.

If you are using metadata driven approach for development and you might generate the required code then you should fetch details from metadata information provided by the class or read it from .js file. ".js" will be helpful if you are not using SAPUI5 runtime.
Hope, this helps.

Good Luck

(1) simulate the different values of an interaction variable,
(2) plot a graph that demonstrates the effect of the interaction on Y for different values of the terms in interaction, and
(3) works well with the models fitted with the lmer() function of the lme4 package?
I have looked in arm, ez, coefplot2, and fanovaGraph packages, but could not find what I was looking for.

v1 <- c(0, 1, NA, 1, NA, 0)
v2 <- c(0, 0, NA, 1, NA, NA)
v3 <- c(1, NA, 0, 0, NA, 0)
df <- data.frame(v1, v2, v3)
df
v1 v2 v3
1 0 0 1
2 1 0 NA
3 NA NA 0
4 1 1 0
5 NA NA NA
6 0 NA 0
One can use the is.na command as follows to calculate the number of rows with at least one missing value - and R would return 4:
sum(is.na(df$v1) | is.na(df$v2) | is.na(df$v3))
Or the number of rows with all three values missing - and R would return 1:
sum(is.na(df$v1) & is.na(df$v2) & is.na(df$v3))
Two questions at this point:
(1) How can I calculate the number of rows where "exactly one" or "exactly two" values are missing?
(2) If I am to do the above in a large data set, how can I limit the scope of the calculation to v1, v2 and v3 (that is, without having to create a subset)?
I tried variations of is.na, nrow and df, but could not get any of them to work.
Thanks!

I just wanted to make sure that I can actually control the motor's speed, and when I got this weird behaviour I though that I was doing something wrong! | aa87357034973c1a07bd81d329c33bf8d694df3c82d22aa9015dd69b3d0323be | ['ad6c3129b75a44cf857802a8d2d3c1cb'] | So I have been given a circuit which supposedly works. The circuit was the the one shown but with a 10k resistor where the scribbles are.
Q17 is an IRLM6344TRPbF N-chanel MOSFET and Q16 is a ZXMP6A17G P-channel MOSFET
This didn't work at first until I removed the scribbled out resistor. After I managed to get it to actually change the output voltage dependant on the PWM signal that is applied, I encountered a weird problem.
The problem was that there was a weird correlation between the PWM duty cycle and the output voltage. When the duty cycle is between 0-30% the output voltage is ranging from 0-11 V and then increasing the duty cycle from 30% to 100% slightly increases the voltage until an output voltage of 11.8 V is achieved.
Can anyone explain why that is the case or what I am misunderstanding/doing wrong?

Except the distance transform function in opencv gives me an image that is exactly the same as the image I use as source. Anyone know what I am doing wrong? Here is the portion of my code:
cvSetData(depthImage, m_rgbWk, depthImage->widthStep);
//gotten openCV image in "depthImage"
IplImage *single_channel_depthImage = cvCreateImage(cvSize(320, 240), 8, 1);
cvSplit(depthImage, single_channel_depthImage, NULL, NULL, NULL);
//smoothing
IplImage *smoothed_image = cvCreateImage(cvSize(320, 240), 8, 1);
cvSmooth(single_channel_depthImage, smoothed_image, CV_MEDIAN, 9, 9, 0, 0);
//do canny edge detector
IplImage *edges_image = cvCreateImage(cvSize(320, 240), 8, 1);
cvCanny(smoothed_image, edges_image, 100, 200);
//invert values
IplImage *inverted_edges_image = cvCreateImage(cvSize(320, 240), 8, 1);
cvNot(edges_image, inverted_edges_image);
//calculate the distance transform
IplImage *distance_image = cvCreateImage(cvSize(320, 240), IPL_DEPTH_32F, 1);
cvZero(distance_image);
cvDistTransform(inverted_edges_image, distance_image, CV_DIST_L2, CV_DIST_MASK_PRECISE, NULL, NULL);
In a nutshell, I grad the image from the kinect, turn it into a one channel image, smooth it, run the canny edge detector, invert the values, and then I do the distance transform. But the transformed image looks exactly the same as the input image. What's wrong?
Thanks!

You need to look int the opencv folder structure that you installed for these header files yourself. Sometimes they're not in the place the install guide tells you they are.
In my computer for example, most of the header files I needed are in:
[INSTALL DIRECTORY]/include/opencv
[INSTALL DIRECTORY]/include/opencv2
but SOME were in:
[INSTALL DIRECTORY]/modules/core/include/opencv2
[INSTALL DIRECTORY]/modules/highgui/include/opencv2 etc
you need to find those include files. Then go to your IDE (eclipse). In eclopse there should be a setting for the "include directories"
Set your IDE to look for include files in the directories where you know the include files are.
Then make sure you add the libraries. Ask if you need help with that.

When you point to yourself and say "me" and point to the child and say "you", they treat the words "me" and "you" the same as they think of names. From my perspective, I am "me", and you are "you", but from your perspective, you are "me" and I am "you". It takes a bit to learn that concept. (And I am the walrus?) | 56fd364ba70e37e90299f7c712c1498eb2d6f7029957b5508e0955fdc141d480 | ['ad8e4ebb92344fabaa5f545afa2829d0'] | Dropbox uses https://github.com/rentzsch/mach_inject to inject code into the Finder process to change the overlay.

e.g.
running
cp -r dir1 dir2
will give you the same result as
cp -r dir1/ dir2
It definitely matters for rsync. In rsync the difference between including and omitting the trailing slash is the difference between syncing the contents of the directory or the directory itself and the contents.
e.g.
rsync -a dir1 dir2
will create a dir1 under dir2
while
rsync -a dir1/ dir2
will create copies of any files in dir1 directly in dir2

However, I do know browser mechanics pretty well and what you are doing is impossible due to security restrictions. One way of doing this, assuming both of the domains (windows) are going to be running within the same browser session, is using message passing window.postMessage(). This is however slightly restrictive because the second window must be open and listening to incoming messages before you post the message.
window.addEventListener('message', function _handler(event) {
// Code for handling the message
// This will automatically remove the listener after receiving one message.
// Good for when you send only one message and don't want the listener lingering and eating up memory.
window.removeEventListener('message', _handler);
});
If you are dealing with a situation where this is not going to be running within the same browser you will have setup some kind of "shared memory" in the form of a simple backend server/service.

So here goes a possible explanation for your issue.
PDFbox has some class initializers that are using the logic "<Class>.class.getClassLoader()" to get an instance of the class loader that is being associated with the class. I expect that line 1852 of your PDFTextStripper.java file being used as source for the version you have been using will contain a reference to this call.
If you decide to mark your Eclipse libraries as "system libraries" then getClassLoader will return "null" as they are being mounted into the bootstrap loader, therefore you are getting a NullPointerException. The subsequent getResourceAsStream call is being tried against a null value and therefore it fails, obviously.
This also will be applicable for Apache XML-Beans 2.6, or Apache POI and other implementations.
Possible easy resolution: remove the flag "system library" from the Eclipse library definitions and getClassLoader will return an instance to the class loader. Thus you won't run into the exception anymore.
Harder resolution: patch the code base for PDFBox and check for null value. If applicable use ClassLoader.getSystemClassLoader() instaead. Re-compile with Maven.

This gave me a file path that I could pass into either torchaudio.load or librosa.core.load. This was also important because I wanted the extra resampling functionality of librosa.core.load, but it doesn't accept file-like objects for loading mp3s.

I'm trying to use either torchaudio or librosa to load a file as a waveform. torchaudio expects the file path as the input, librosa can either use a file path or file-like object. I tried using s3fs to get the url to the file but torchaudio doesn't recognize it as a file. And apparently SageMaker has problems installing librosa so I can't use that. What should I do?

sentence = "ASK NOT WHAT YOUR COUNTRY CAN DO FOR YOU ASK WHAT CAN YOU DO FOR YOUR COUNTRY"

Ask would have the value 0, Not would have the value 1, What would have the value 2, Your would have the value 3.

Ask then is repeated in the 9th position, so I'm wondering how I could make all of the repeated words have the 1st value of them. So the 9th ask, should have the value 0. The 10th word, what would have the value 3, and so on.

By using Comamnd-T and FZF you can do the search with an extremely fast "fuzzy" mechanism for:
Opening files and buffers
Jumping to tags and help
Running commands, or previous searches and commands
with a minimal number of keystrokes.
As you can see
I always search in command history by opening a new terminal and hit:
CTRL+R
In addition to searching in all folders recursively by writing in any terminal tab:
fzf
Then start your file name
ABC
Also, you can write inside vim
:CommandT
Really helpful especially in large folders.

First of all, place your data table in a wrapper div:
<div id="dataTableWrapper" style="width:100%" class="dataTableParentHidden">
...data table html as described in jQuery Data Table documentation...
</div>
In CSS:
.dataTableParentHidden {overflow:hidden;height:0px;width:100%;}
This solution hides the data table without using "display:none".
After the data table initialization you have to remove class from wrapper to reveal the table:
$('#yourDataTable').DataTable(...);
$('#dataTableWrapper').removeClass('dataTableParentHidden');

Do you hear any high-pitched whistling and clicking as it tries to synch up to the signal? That's usually a sign that the monitor doesn't work at that resolution, and why it can only display a much lower resolution.
You don't say the vintage of the display, but my hunch it probably can't go much more than 1024 x 768 which was high-resolution way back when except on expensive CAD/CAM and graphics systems which used special video cards and monitors capable of the resolutions we use every day now.

This is a new laptop. The user will receive a new license and should use that to setup the machine. It's also cleaner that way too. |

https://github.com/camenergydatalab/EnergyDataSimulationChallenge/blob/master/challenge2/data/total_watt.csv
I want to visualize this csv file as clusters.
My ideal result would be the following image.(Higher points (red zone) would be higher energy consumption and lower points (blue zone) would be lower energy consumption.)
I want to set x-axis as dates (e.g. 2011-04-18), y-axis as time (e.g. 13:22:00), and z-axis as energy consumption (e.g. 925.840613752523).
I successfully visualized the csv data file as values per 30mins with the following program.
from matplotlib import style
from matplotlib import pylab as plt
import numpy as np
style.use('ggplot')
filename='total_watt.csv'
date=[]
number=[]
import csv
with open(filename, 'rb') as csvfile:
csvreader = csv.reader(csvfile, delimiter=',', quotechar='|')
for row in csvreader:
if len(row) ==2 :
date.append(row[0])
number.append(row[1])
number=np.array(number)
import datetime
for ii in range(len(date)):
date[ii]=datetime.datetime.strptime(date[ii], '%Y-%m-%d %H:%M:%S')
plt.plot(date,number)
plt.title('Example')
plt.ylabel('Y axis')
plt.xlabel('X axis')
plt.show()
I also succeeded to visualize the csv data file as values per day with the following program.
from matplotlib import style
from matplotlib import pylab as plt
import numpy as np
import pandas as pd
style.use('ggplot')
filename='total_watt.csv'
date=[]
number=[]
import csv
with open(filename, 'rb') as csvfile:
df = pd.read_csv('total_watt.csv', parse_dates=[0], index_col=[0])
df = df.resample('1D', how='sum')
import datetime
for ii in range(len(date)):
date[ii]=datetime.datetime.strptime(date[ii], '%Y-%m-%d %H:%M:%S')
plt.plot(date,number)
plt.title('Example')
plt.ylabel('Y axis')
plt.xlabel('X axis')
df.plot()
plt.show()
Although I could visualize the csv file as values per 30mins and per days, I do not have any idea to visualize the csv data as clusters in 3D..
How can I program it...?

(If you have any recommendations other than VARMA or VAR, please let me know.)
The data I can use for training is as following;
（https://github.com/soma11soma11/EnergyDataSimulationChallenge/blob/master/challenge1/data/training_dataset_500.csv）

11999 23 500 2013 6 22.7 122.9 586
As shown above, I can use data from July 2011 to May 2013 for training.
Using the training, I want to predict energy production on June 2013 for each 500 house.
By using statsmodels.api.tsa.filters.hpfilter, I succeeded to get rid of trend component from "Daylight".
import csv
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import statsmodels.api as sm
df = pd.read_csv('../../data/training_dataset_500.csv')
x = df.loc[df.House==1, 'Daylight']
x_smoothed, x_trend = sm.tsa.filters.hpfilter(x, lamb=129600)
fig, axes = plt.subplots(figsize=(12,4), ncols=3)
axes[0].plot(x)
axes[0].set_title('raw x')
axes[1].plot(x_trend)
axes[1].set_title('trend')
axes[2].plot(x_smoothed)
axes[2].set_title('smoothed x')
plt.show()
I have 2 questions(stack) here.
Stack1
I can not remove seasonal component.
Although I can get rid of the trend component, I cannot remove seasonal component to make the time series data stationary.
(I need to make the time series data stationary in order to get a good prediction.)
Stack2
I want to implement VARMA(or VAR) model to get the prediction.
But writing the models are difficult for me and cannot write a proper code...
Again, If you have any recommendations other than VARMA or VAR, please let me know.
Following are my code.(I tryed to implement VAR model)

The only helpful thing I have found online is this function but it doesn't get me all the way there.

Would I be better off coming up with a macro?

I want to set a specific opacity on each items of my scene. I use setOpacity : setOpacity method, but its not the result i hope.
I want to have for example one item opaque and an other transparent (to see the desktop, or the other application).
But if i dont set the opacity of the QGraphicsView to 0.5, i have not the transparancy.
And if the QGraphicsView is set to 0.5, the item is not real opaque.
What should i do ?
Thanks you.

How can I config my app, that it is loading the A) css itself, B) the fonts loaded in css and C) the images from a relative path depending to the parent-folder the app is located?
My complete vue app is currently running without extra webpack config file. I already know, I would need to create a webpack.config.js, but I don't know what plugins or configuration is necessary.
The app is full functional under absolute path http:whatever.local/ of course.
But I need to deliver the app complete independent from absolute path, so customer can use it under folder structure he wants and I don't know jet. http:customerssite.com/i-dont-know-his-structure/vue-app/ (I just don't know).
Thank you very much.

1) Relative Path to assets at all.
To have the web-app functional in every nested folder, you need to load all assets from relative starting point.
Solution: baseUrl = './' (the folder itself, were the html starts loading the vue app.)
Documented here: https://cli.vuejs.org/config/#baseurl
module.exports = {
baseUrl: './',
}
2) ignore url paths in css-loader
To be able to use relative paths in the urls used in css for images and fonts, you need to avoid that the css-loader (webpack) is trying to manipulate/controll your used urls.
Solution: Configure this css-loader with option url: false. And just use the relative url, that starts from the folder were the html starts loading.
Documented here: https://cli.vuejs.org/guide/css.html#css-modules
module.exports = {
baseUrl: './',
css: {
loaderOptions: {
css: {
url: false,
}
}

A better way to read all lines into a vector is:
string line;
while(getline(inFile, line)
text_list.push_back(line);
Your loop will break once you've read an EOF or when any other error has occured.
Another method is using iterators and the algorithm library:
copy(istream_iterator<string>(inFile), istream_iterator<string>(),
back_inserter(text_list));
It's up to you which one you prefer.

Each code is 8 digits long.
Each digit can be any of the following:
0-9 numbers
26 lower case alpha
26 upper case alpha
Total 62 choices per.
If I've done the math right 62^8 (and I could be completely wrong, which is why I'm asking the brains) being 8 digits long that could generate:
218,340,105,584,896 codes. Once a code is generated it cannot be generated again.
What I'm curious in is let's say over x time the amount of generated codes ramp up into the millions and continues climbing at a steady pace.
Now let's say a third party enters and writes a program that can generate my rudimentary 8 digit code. They can also check to see if its a valid code. Given that there are approximately a million codes already generated which keeps gaining everyday. Is there a formula to see the approximate time it would take somebody to generate a valid code? Say they can generate and check about 10 per second or so. I know I can simply add more digits to my code but the idea is the shorter the better in this scenario. I'm curious if this is secure enough. We're not talking about the keys to the castle here.

You have to run systemctl to check the service to see what is wrong
sudo systemctl status postgresql
It gives something like this
systemd[1]: Starting PostgreSQL database server...
postgres[3902]: "/var/lib/postgres/data" is missing >
postgres[3902]: su - postgres -c "initdb --locale >
and it tells you to run the su command listed above. But this requires the password of the user postgres. To go around this we sudo the command instead.
sudo su - postgres -c "initdb --locale en_US.UTF-8 -D /var/lib/postgres/data'"
When this command is finished it tells you to run pg_ctl -D /var/lib/postgres/data start, but instead just start it via systemctl.
sudo systemctl enable postgresql

Java has some native graphics, but libraries are far better.
Java is good for games (far better than python even with PYGame). If your game is complex, then you definitely want to use C(++).
There are libraries that allow animations, although you could just program it yourself.
As previously mentioned, Processing is good for non-serious applications. But if you want a full-fledged IDE then you definitely want Eclipse.

It is absolutely clear how to transform Cartesian system to Shperical, simply by:
enter image description here
but the thing that is not clear to me - how to transform (x,y,z) to (theta, lambda, r) using matrix?
I assume that it should be something like this:
a = (x,y,z), b = (theta, lambda, r), where a and b is column vector and there is some matrix M such as:
a = M b.
Then I found in the web such matrix, the view is:
enter image description here
but when I start multiplying I do not get the equations on the first image...
So how does transformation matrix look and what am I confusing..?
Thank you in advance.

The first one is "fast" pulsating time, the second one is "slow" meantime. This concept comes from perturbation theory, where you can define different time scales. And as far as I understand, if we average by $\tau$ over a period and we average periodic functions, so it must be zero |

If your object has a fixed length you can received specified amount of bytes on the other end and then create your object.
Otherwise you can send delimiters (symbol or sequence of symbols that you are not using in your object) between your objects and keep reading received data byte by byte until you see the delimiter.

If you are analyzing the related effect sizes reported on your topic and they are (0.1) (0.3) (0.24) and you produce an effect of (0.4) then that may be "large". Conversely, if all the related literature has effects of (0.5) (0.6) (0.7) and you have the effect of (0.4) it may be considered small. I know this is a trivial example but imperatively important.

With Txtfmt highlighting enabled, you could add arbitrary fg/bg colors and formats to your document.
Caveat: Txtfmt accomplishes its formatting through the use of invisible tokens inserted in the buffer, but these could be stripped easily with a pre-processing step when you generate your final document.

I need to change the mailto url based on the language i selected before.

So I create a JavaScript function "changeEmailAdress()":
function changeEmailAdress(){
var languageSelected = document.getElementById("languageSelected");
if (languageSelected.value == "AR")
languageSelected.setAttribute('href',"mailto:<EMAIL_ADDRESS>");
else if(languageSelected.value == "US"){
languageSelected.setAttribute('href',"mailto:<EMAIL_ADDRESS>");
}
}
This function does not work, but I am not able to realize why.
The language selected, for example "AR" "US", is also displayed on the url of the website: "www.site.com/es/#AR", so I also thought about getting those character from the website url and make the conditional from there. Is it possible?

is it like this or like this
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
//Here you can inflate the icons that you want...
getMenuInflater().inflate(R.menu.main, menu);
return true;
