f=1;
break;
}
}
if(f==0)
a.push_back(x.at(i));
}
if(a.size()==2)
cout<<"YES\n";
else
cout<<"NO\n";
}
return 0;

library in C11 or C99 good practice : <p>What is better idea: write library which will be used by others in C11 or C99? Is it good justification that many people rather use C99 in theis project than C11 or it's not true? And what is better for microcontrollers? I am not professional and I want to have good excuse to not use generic C11 :P Thank you for your help. I hope it's not 'silly' question.</p>

Deleteall character from filename before the last underscore _ : Ho to delete all characters up to and including the last underscore `_` before the `.ext` from all filenames recursive in the CWD?
Is this best done by split and replace or regex (`^[^_]+_` ?)? The code below does not work (no erros msg.)
aaa_bbb_000_xxx.txt ---> xxx.txt
__abc123_zzzz.txt ---> zzzz.txt
111222.txt ---> 111222.txt
Code:
import os
cwd = os.getcwd()
paths = (os.path.join(cwd, filename)
for cwd, _, filenames in os.walk('cwd')
for filename in filenames)
for path in paths:
newname = path.replace(^[^_]+_)
if newname != path:
os.rename(path, newname)

How to use forEach in vueJs? : <p>I have a response like below from an API call,</p>
<p><a href="https://i.stack.imgur.com/lMr5I.png" rel="noreferrer"><img src="https://i.stack.imgur.com/lMr5I.png" alt="response"></a></p>
<p>Now, I have to repeat the whole arrays inside the arrays. How do I do that in VueJS?</p>
<p>I have searched for using forEach.. nowhere I found forEach usage like key|value pair.</p>
<p>Can anyone help me on how to fetch the values from that arrays by using either forEach or any else(VueJS)?</p>

Android how can i check if calendar date has been selected : I am making a task manager application where I require the following details:- name (string), description (string), date (long) and importance (int).
I am currently stuck on figuring out how to get date and also see if date from calendarView has been selected.
TextView name, description, importance;
CalendarView calendar;
Button submit;
ArrayList<Task> myTasks = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create_task);
name = (TextView)findViewById(R.id.CreateTaskNameET);
description = (TextView)findViewById(R.id.CreateTaskDescriptionET);
importance = (TextView)findViewById(R.id.CreateTaskImportanceET);
calendar = (CalendarView) findViewById(R.id.CreateTaskCalender);
submit = (Button)findViewById(R.id.CreateTaskSubmitBtn);
submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Task myTask = new Task(name.getText().toString(),
description.getText().toString(),
calendar.getDate(),
Integer.parseInt(importance.getText().toString()));
myTasks.add(myTask);
}
});
}
public void validateRule(EditText name, EditText description, CalendarView calendar, EditText importance){
if(name.getText().equals("")){
}
else if(description.getText().equals("")){
}
else if(calendar.getDate()){
}
}
Once again, how can i determine if the date has been selected as it's one of my validation rule. Thanks

How to write Repository method for .ThenInclude in EF Core 2 : <p>I'm trying to write a repository method for Entity Framework Core 2.0 that can handle returning child collections of properties using .ThenInclude, but I'm having trouble with the second expression. Here is a working method for .Include, which will return child properties (you supply a list of lambdas) of your entity.</p>
<pre><code>public T GetSingle(Expression<Func<T, bool>> predicate, params Expression<Func<T, object>>[] includeProperties)
{
IQueryable<T> query = _context.Set<T>();
foreach (var includeProperty in includeProperties)
{
query = query.Include(includeProperty);
}
return query.Where(predicate).FirstOrDefault();
}
</code></pre>
<p>Now here is my attempt at writing a method that will take a Tuple of two Expressions and feed those into a .Include(a => a.someChild).ThenInclude(b => b.aChildOfSomeChild) chain. This isn't a perfect solution because it only handles one child of a child, but it's a start. </p>
<pre><code>public T GetSingle(Expression<Func<T, bool>> predicate, params Tuple<Expression<Func<T, object>>, Expression<Func<T, object>>>[] includeProperties)
{
IQueryable<T> query = _context.Set<T>();
foreach (var includeProperty in includeProperties)
{
query = query.Include(includeProperty.Item1).ThenInclude(includeProperty.Item2);
}
return query.Where(predicate).FirstOrDefault();
}
</code></pre>
<p>Intellisense returns an error saying "The type cannot be inferred from the usage, try specifying the type explicitly". I have a feeling it's because the expression in Item2 needs to be classified as somehow related to Item1, because it needs to know about the child relationship it has. </p>
<p>Any ideas or better techniques for writing a method like this? </p>

Why I can't get javascript values into my php5 code? : <p>I have this code: </p>
<pre><code><?php $html=file_get_contents('testmaker_html.html');
echo $html;
?>
<script type="text/javascript">
document.getElementById('save_finaly_TEST').addEventListener("click", function(){
cover = document.getElementById('cover').value;
keywords = document.getElementById('keywords').value.split(",");
notificationAboutElement = "Ok!";
notifyMe(notificationAboutElement);
html_saver();
<?php $test_html = "<script>document.write(html)</script>"?>
});
</script>
<?php
$new_test = rand().".html";
$myfile = fopen($new_test, "w") or die("Unable to create file!");
write($myfile, $test_html) or die("Can't write to file");
fclose($myfile) or die("Can't close the file!");
echo $new_test;
?>
<script type="text/javascript">
console.log("$test_html: " + <?php echo $test_html; ?>);
console.log("$new_test: " + <?php echo $new_test; ?>);
</script>
</code></pre>
<p>Why is <code>$test_html</code> empty? I know the php and javascript is not on same server but this methodd to get values many times worked for many people. Than what can be wrong with this?</p>

how can I run wordpress on GCP cloud run? : according to GCP https://cloud.google.com/wordpress/
but so far cloud run i the best option for no teche person however in order to run cloud run wordpresss must be on a container.
using the vM with bitnami wordpress still need some kind technicals and management which don't want to deal with. on the other hand wordpress n App engine standard is doing similar job cloud run with some differences.
wordpress app engine vs wordpress cloud run? and if cloud run is much better. how?

Removing duplicates with unique index : <p>I inserted between two tables fields A,B,C,D, believing I had created a Unique Index on A,B,C,D to prevent duplicates. However I somehow simply made a normal index on those. So duplicates got inserted. It is 20 million record table.</p>
<p>If I change my existing index from normal to unique or simply a add a new unique index for A,B,C,D will the duplicates be removed or will adding fail since unique records exist? I'd test it yet it is 30 mil records and I neither wish to mess the table up or duplicate it.</p>

AWS API Gateway ARN : <p>One of the things that drives me nuts is that AWS has loads of docs about the format of an ARN, but doesn't have any kind of generator to make you confident that the ARN is correct.</p>
<p>In IAM, I'm trying to set up a policy to allow access to an API Gateway and I've read the following docs about it:</p>
<ul>
<li><a href="http://docs.aws.amazon.com/apigateway/latest/developerguide/permissions.html#api-gateway-control-access-using-iam-policies" rel="noreferrer">http://docs.aws.amazon.com/apigateway/latest/developerguide/permissions.html#api-gateway-control-access-using-iam-policies</a></li>
<li><a href="http://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html#arn-syntax-apigateway" rel="noreferrer">http://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html#arn-syntax-apigateway</a></li>
<li><a href="http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/AWSHowTo.iam.policies.arn.html" rel="noreferrer">http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/AWSHowTo.iam.policies.arn.html</a></li>
</ul>
<p>But I can't get any ARN to validate, even just a wide open API Gateway ARN. See screenshot:</p>
<p><a href="https://i.stack.imgur.com/sO02S.png" rel="noreferrer"><img src="https://i.stack.imgur.com/sO02S.png" alt="open arn called invalid"></a></p>
<p>What am I doing wrong here?</p>

using regex to make a number of checks : <p>I am very confused by regex expression checks. I am trying to make several checks on two different strings in php. The first string must be 3-8 characters long, begin with a lowercase letter, and consist entirely of lowercase and the second must be 6-12 characters long, begin with a number, and end with any character that is not a letter or number. So if I had $first = "ttyl45" and $second = "6ttyl56*" These would pass the checks. I just don't know how to go about doing this because regex is very confusing to me I looked all over the internet but I'm still stuck</p>

Prevent an exception when I cancel an openfiledialog? : <p>I am having a problem when I click cancel on an openfiledialog in c#, it throws an exception. This is my code:</p>
<p>I tried to look at some other Stackoverflow solutions but none of them work. Here is a example:</p>
<pre><code>private void BtnCargarImagen_Click(object sender, EventArgs e)
{
//OFD = openfiledialog
OFD.ShowDialog();
PicFotografia.Image = Image.FromFile(OFD.FileName);
MessageBox.Show("LA IMAGAN HA SIDO CARGADA");
DialogResult result;
if (result == DialogResult.OK)
{
return OFD.FileName;
}
return null;
</code></pre>
<p>When the "if" part is placed on the code, it marks error on both "returns". </p>
<p>Without the dialog result part from top to bottom when I click on cancel, it marks an exception.</p>
<pre><code>private void BtnCargarImagen_Click(object sender, EventArgs e)
{
//OFD = openfiledialog
OFD.ShowDialog();
PicFotografia.Image = Image.FromFile(OFD.FileName);
MessageBox.Show("LA IMAGAN HA SIDO CARGADA");

How to initalize a string array in a main Java method : I have written some code which creates and initializes a String ArrayList. Is it possible to declare the arguments directly in to the String [] args method itself, rather than creating an extra String arrayList? I have done some searching on youtube/ google etc but didn't find a clear answer. Thanks
public class sampleCode{
public static void main(String[] args ) {
String[]args2 = {"en", "es"};
if( args2[0].equals("en")) {
System.out.println("english option");
}
else if( args2[1].equals("es")) {
System.out.println("spanish option");
}

Make a calendar view for events in python tkinter : <p>So what I'm trying to do is to make a calendar frame, just like the view of google calendar or any other calendar program really, where I can select a day and see the events I have to do on that day and it's time using python tkinter. Currently on my database I have events with date, starting time and ending time. Note that I am using python 3. Can anyone please give me a clue for how to do it or even send a link to a website where it says how to do it. But please, I'm not searching for a date picker just a calendar showing me what thing I should do when. Thank you ;)</p>

thread.sleep not doing what is supposed to : <p>So, the program is for school and i am having some problems, the basic premise is to have to user choose shape, size and colour, then draw the shape or animate it to move across the screen. </p>
<p>My programs works fine without the thread.sleep (it moves across the screen instantly). When i added the thread.sleep it was not working and waited 10 seconds before immediately moving to the end. </p>
<p>After testing around, it seems to have some correlation with the for loop it was in as when the for loop was to 1000 it waited 10 seconds then moved 1000 spaces instantly but when the for loop was 100 it only took one second to move 100 spaces instantly.</p>
<p>My understanding was that it should just wait 10 milliseconds before going into the for loop again.</p>

How to change the placeholder color in android app created using React Native : <p>I'm creating an Android app using React Native in which there's a form.

Retry logic with CompletableFuture : <p>I need to submit a task in an async framework I'm working on, but I need to catch for exceptions, and retry the same task multiple times before "aborting".</p>
<p>The code I'm working with is:</p>
<pre><code>int retries = 0;
public CompletableFuture<Result> executeActionAsync() {
// Execute the action async and get the future
CompletableFuture<Result> f = executeMycustomActionHere();
// If the future completes with exception:
f.exceptionally(ex -> {
retries++; // Increment the retry count
if (retries < MAX_RETRIES)
return executeActionAsync(); // <--- Submit one more time
// Abort with a null value
return null;
});
// Return the future
return f;
}
</code></pre>
<p>This currently doesn't compile because the return type of the lambda is wrong: it expects a <code>Result</code>, but the <code>executeActionAsync</code> returns a <code>CompletableFuture<Result></code>. </p>
<p>How can I implement this fully async retry logic?</p>

Android Studio: how to show author of just selected line : <p>I noticed a pretty feature in Visual Studio Code (don't know if it's due to the GitLens extension): when I'm editing a line I can see the GIT annotation of that line including author, time of last edit and commit message.</p>
<p><a href="https://i.stack.imgur.com/6ZLRF.png" rel="noreferrer"><img src="https://i.stack.imgur.com/6ZLRF.png" alt="enter image description here"></a></p>
<p>This is quite cool, since it does not take a big amount of space as the "annotations" pane that you can enable in Android Studio. It's fast, easy, straightforward.</p>
<p>My question is: is there any Android Studio extension, as far as you know, allowing a similar visualization?</p>
<p>Thank you

Replace array item with another one without mutating state : <p>This is how example of my state looks:</p>
<pre><code>const INITIAL_STATE = {
contents: [ {}, {}, {}, etc.. ],
meta: {}

</code></pre>
<p>I need to be able and somehow replace an item inside contents array knowing its index, I have tried:</p>
<pre><code> return {
...state,
contents: [
...state.contents[action.meta.index],
{
content_type: 7,
content_body: {
album_artwork_url: action.payload.data.album.images[1].url,
preview_url: action.payload.data.preview_url,
title: action.payload.data.name,
subtitle: action.payload.data.artists[0].name,
spotify_link: action.payload.data.external_urls.spotify
}
}
]
}
</code></pre>
<p>where <code>action.meta.index</code> is index of array item I want to replace with another contents object, but I believe this just replaces whole array to this one object I'm passing. I also thought of using <code>.splice()</code> but that would just mutate the array?</p>

<p>When I try importing <code>Stream</code> like this: <code>import java.util.*;</code> I get a "the symbol Stream cannot be resolved" error. When I instead import <code>Stream</code> like this: <code>java.util.stream;</code> things work as expected. Why does this happen? I don't use <code>Stream</code> or anything named "stream" elsewhere in my program, so I don't think it's a name conflict? </p>

What's the point of AsyncSubject in RXJS? : <p>The documentation for <code>RxJS</code> defines <code>AsyncSubject</code> as follows:</p>
<blockquote>
<p>The AsyncSubject is a variant where only the last value of the Observable execution is sent to its observers, and only when the execution completes.</p>
</blockquote>
<p>I don't see where / why I would ever need to use this variant of subject. Can someone provide an explanation or a real-world example to illustrate why it exists and its advantages?</p>

two progress bars with same styles (default) look different in android : In my android application i am using an open source library. This library has an activity which creates a progress bar (no style) using below code . say it progressBar1 .
private void createProgressBar() {
LayoutParams params = new LayoutParams(-1, -2); // match_parent , wrap_content
params.addRule(13); //center in parent
ProgressBar = new ProgressBar(this);
ProgressBar.setLayoutParams(params);
RootLayout.addView(ProgressBar);
ProgressBar.setVisibility(8); //View.GONE
}
I am also creating a progress bar in my app using exact same code above , Say ProgressBar2.
But the two progress bars look different . I donot know whats the reason .
I want both the progress bars to look same .
I also tried changing the progressBar2 by adding it in xml and using from there using below code:
<ProgressBar
android:id="@+id/progressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:indeterminate= "true"
android:visibility="gone"/>
using it in java as:
progressBar = (ProgressBar) findViewById(R.id.progressBar);
progressBar.setVisibility(View.VISIBLE);
still the progressBar2 Looks the same and both progressBar1 and progressBar2 look different ... do not know why?

Differences between commands run in .bat file and cmd.exe : I wanted to download scoop installer and I find out that my command is not working in a .bat file but works when I copy/paste it in powershell.
Here is the command and a picture to make things perfectly clear :
iex (new-object net.webclient).downloadstring('https://get.scoop.sh')
[output of powershell][1]
Could somebody explain to me why it is the case and maybe the things that we need to be aware of when we put commands in .bat file ?

Invoking a function without parentheses : <p>I was told today that it's possible to invoke a function without parentheses. The only ways I could think of was using functions like <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/apply"><code>apply</code></a> or <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/call"><code>call</code></a>.</p>
<pre><code>f.apply(this);
f.call(this);
</code></pre>
<p>But these require parentheses on <code>apply</code> and <code>call</code> leaving us at square one. I also considered the idea of passing the function to some sort of event handler such as <a href="https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/setTimeout"><code>setTimeout</code></a>:</p>
<pre><code>setTimeout(f, 500);
</code></pre>
<p>But then the question becomes "how do you invoke <code>setTimeout</code> without parentheses?"</p>
<p>So what's the solution to this riddle? How can you invoke a function in Javascript without using parentheses?</p>

java.lang.ClassCastException: org.gephi.graph.impl.GraphStore$NodeIterableWrapper cannot be cast to org.gephi.graph.api.Node at org.............execute(.....java:92)
The code in which the error occured is as follows:
Node[] nodes = graph.getNodes().toArray();
for (Node n: nodes){
.....
List<Node> neighborNodes = new LinkedList<Node>();
for(Node m: nodes){
NodeIterable iter = graph.getNeighbors(m);
neighborNodes.add((Node) iter);
The last line causes the error. Is it possible via NodeIterable to insert the neighbors as nodes in the list "neighborNodes" without this cast.
