what algorithm does STL size() use to find the size of string or vector in c++ : what algorithm does STL size() use to find the size of string or vector in c++?
I know that working of strlen() is dependent on finding the NUL character in the c char array but I want to know how does size() function work to find the size of string which is not null terminated as we know.
Does stl containers use some sort of pointers to mark the ending of container?
And does that help in finding the size or something else?

Use Moment to get month of Date object : <p>I'm sure this is a simple thing but I haven't been able to find the specific syntax in any of the documentation or in any related posts. </p>
<p>In order to get a month-picker to work i need to instantiate a new <code>Date</code> object when my controller initializes. </p>
<p><strong>Controller</strong></p>
<pre><code>scope.date = new Date();
</code></pre>
<p>This creates a date object with the following format: </p>
<blockquote>
<p>Mon Feb 01 2016 15:21:43 GMT-0500 (Eastern Standard Time)</p>
</blockquote>
<p>However when I attempt to pull the month from the date object, using moment, I get the error: </p>
<blockquote>
<p>enter code here</p>
</blockquote>
<p><strong>getMonth method</strong></p>
<pre><code>var month = moment().month(scope.date, "ddd MMM DD YYYY");
</code></pre>
<p>Any idea how to pull the month from the above date object without using substring?</p>

ng-reflect-model shows correct value but not reflecting in input : <p>Encountered a very weird issue where my application misbehaves in a very specific user case. I have a portal where users can add questions and answers and then edit them. In this case when I remove a set(q+a) and then try adding it, the model is getting updated but my view takes values from placeholders and updates itself. Here I am just splicing and pushing values in an array and rendering using ngFor. The last element is a dummy and that is used to enter values which are pushed up.</p>
<p>Attaching a screenshot if it makes any sense.</p>
<p>You can see that for the textbox, the ng-reflect-model shows correct question, but the element itself displays the placeholder text.</p>

How To Configure Queue Name for Queue Trigger In Azure Function App : <p>I'm creating a function app in Azure and want to use a queue trigger.
I know how to configure the queue name at design time, e.g:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>[FunctionName("MyTestFunction")]
public static void Run([QueueTrigger("myqueue-items", Connection = "testdelete")]string myQueueItem, TraceWriter log)</code></pre>
</div>
</div>
</p>
<p>However, I'd like to be able to define and reference it in a configuration file.
I'm aware of the existence of function.json (Probably this one), host.json and local.settings.json, but I don't know how to set a queue name in there and have it be referenced in the function.</p>
<p>If I deploy a freshly created function created in visual studio (With the new 15.3 update), I can see the following in the function.json file post deployment (even though the file doesn't exist when i develop locally):</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code> "bindings": [
{
"type": "queueTrigger",
"queueName": "myqueue-items",
"connection": "testdelete",
"name": "myQueueItem"
}</code></pre>
</div>
</div>
</p>
<p>I've found that if I create that file, and change the "queueName" to something that doesn't match the value in the actual function, it unfortunately doesn't override it (That would have been too easy I guess).</p>
<p>How can I reference the bindings in the function.json in the functions QueueTrigger attribute?</p>
<p>Presumably whatever the solution is will allow me to do the same with poison queue handling?</p>
<p>The reason I want to do this, is because I need to deploy multiple instances of the exact same function, but pointing each one at a different queue (In order to get around max memory limitations).</p>
<p>Thanks.</p>

Activity can still call unbinded service method. Is it normal? : Please forgive my unperfect English. I am studying services, and I have written a code to bind a service by clicking on a button, run a method of the service by clicking on another button and unbinding service by clicking on a third button.
If I try to run the method of the service before binding I get, obviousy, an error message, while if I first bind the service the method is normally called.
The question is, if I click on the third button to unbind the service, despite the service native method onUnbind(Intent intent) gives me a positive feedback, I am still able to call the service method from the main activity like if it should still be bound.
Here is the Service code
<pre>
package com.antonello.tavolaccio4;
import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
import android.support.annotation.Nullable;
/**
* Created by Antonello on 14/05/2017.
*/
public class Servizio extends Service{
public IBinder binder=new MyBinder();
@Nullable
@Override
public IBinder onBind(Intent intent) {
return binder;
}
@Override
public boolean onUnbind(Intent intent){
System.out.println("unbinded");
return false;
}
public class MyBinder extends Binder{
Servizio getService(){
return Servizio.this;
}
}
public void metodo(){
System.out.println("Metodo del service");
}
}
</pre>
and here is the MainActivity code:
<pre>

import android.app.Activity;
import android.app.Service;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;

import android.os.IBinder;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
ServiceConnection serviceConnection;
Servizio servizio;
Button button;
Button button2;
Button button3;
boolean bound;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button=(Button)findViewById(R.id.button);
button2=(Button)findViewById(R.id.button2);
button3=(Button)findViewById(R.id.button3);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent=new Intent(getApplicationContext(),Servizio.class);
bindService(intent,serviceConnection, Service.BIND_AUTO_CREATE);
}
});
button2.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
servizio.metodo();
}
});
button3.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
unbindService(serviceConnection);
}
});
serviceConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
Servizio.MyBinder binder=(Servizio.MyBinder)service;
servizio=binder.getService();
bound=true;
System.out.println(bound);
}
@Override
public void onServiceDisconnected(ComponentName name) {
}
};
}
}
</pre>
Is there anything wrong in my <b>unbindService</b> method?
Thank you for any help.

In React.js should I make my initial network request in componentWillMount or componentDidMount? : <p>In the react docs it recommends making initial network requests in the <code>componentDidMount</code> method:</p>
<blockquote>
<p><code>componentDidMount()</code> is invoked immediately after a component is mounted. Initialization that requires DOM nodes should go here. If you need to load data from a remote endpoint, <strong>this is a good place to instantiate the network request.</strong> Setting state in this method will trigger a re-rendering.</p>
</blockquote>
<p>If <code>componentWillMount</code> is called before rendering the component, isn't it better to make the request and set the state here? If I do so in <code>componentDidMount</code>, the component is rendered, the request is made, the state is changed, then the component is re-rendered. Why isn't it better to make the request before anything is rendered?</p>

NuGet Server for .NET Core : <p>The <a href="https://www.nuget.org/packages/NuGet.Server/" rel="noreferrer">NuGet.Server</a> package is used to create a ASP.NET MVC NuGet server and it works just fine. There is another package <a href="https://www.nuget.org/packages/NuGet.Server.Core/" rel="noreferrer">NuGet.Server.Core</a> that is expected to do the same when hosted within a ASP.NET Core (perhaps 1.0 or 1.1?).</p>
<p>The first one creates 'Packages' folder right beneath the main folder used as a package repository.<br>
No such things happens after installing the Core version. I tried both root and a dedicated folder. Googling a bit, I found no info about installing the package and integrating it in a ASP.NET Core app.</p>
<p>Has anyone succeeded in installing the Core version? Also, there's another version <a href="https://www.nuget.org/packages/NuGet.Server.V2/" rel="noreferrer">NuGet.Server.V2</a> which depends on NuGet.Server.Core, however it requires .NET Framework 4.6.1. This makes me think that <strong>NuGet.Server.Core is not targetting .NET Core</strong> at all. </p>
<p>If so, the name must be somewhat misleading, I guess...</p>

Java - Do a line break in JTextPane without HTML : I've been for a while searching through here and other Java forums. Also googling it, but I haven't found anything that matches my expectations (a line break, basically). I've achieved this:
public final void messageRoom (String message, Boolean bold, Color color) {
StyledDocument document = new DefaultStyledDocument();
SimpleAttributeSet attributes = new SimpleAttributeSet();
if(bold) {
attributes.addAttribute(StyleConstants.CharacterConstants.Bold, Boolean.TRUE);
}
attributes.addAttribute(StyleConstants.CharacterConstants.Foreground, color);
try {
document.insertString(document.getLength(), message, attributes);
} catch (BadLocationException ex) {
System.out.println("ex");
}
chatArea.setStyledDocument(document);
}
That allows me to send messages to a chat room I'm creating, how can I make the line break to go to the next line?

(with examples use-cases if possible)</p>

ColdFusion IPv6 to unsigned int 128-bits : I needed to create a function that could convert an IPv6 address to its numeric representation.
Working with IPv4 is pretty straight forward as it uses an 32-bit unsigned int for its numerical representation. IPv6 is represented by an 128-bit unsigned int. That size of a number is too large for the builtin ColdFusion bit logic functions to use.
This function must make use of the underlying Java system to make the conversion.

What do the TargetFramework settings mean in web.config in ASP .NET MVC? : <p>One of our ASP.NET MVC 5 web applications has the following web.config settings:</p>
<pre><code><system.web>
<compilation debug="true" targetFramework="4.6" />
<httpRuntime targetFramework="4.5" />
<!--... many other things -->
</system.web>
</code></pre>
<p>It is not clear why are two targetFramework settings, and it seems to be wrong to compile targeting 4.6 then trying to run under 4.5...</p>

Proof if property quantity is > 1 then push price * quantity : the function below loops through the properties of the objects in `var input` which is for example `[ { name: 'Nagellack 15 ml 2 2', id: '1057290002', price: '1.9', brand: 'a.o.n.', quantity: 1 }, { name: 'Ceramic Nail Lacquer 6 ml Coral Reef Coral Reef', id: '1027410001', price: '6.9', brand: 'Artdeco', quantity: 1 } ]` and pushes new objects into `products_list []`
I'm trying to set up a condition which proofs when the quantity of an object is > 1 and then multiplies the price with the quantity. The issue here is, that I only get the price of one product although there is a quantity of 2.
I don't know which is the best place in the code set up the condition.
function() {
var input = {{dl_purchase_products}};
var products_list = [];
for(i=0;i<input.length;i++){
products_list.push({
id: input[i].id.slice(0,6),
price: input[i].price, <---- this should be the price for 2
quantity: input[i].quantity
});
}
return products_list;
}
Thanks a lot!

Use R to look for files in all sub-directories : <p>I am on a machine running Windows 10 with RStudio (0.99.893). I am running into a problem whereby I want to include ALL filetypes (.cnv) into one dataframe. In the past all the files have been in one directory so this following has worked fine:</p>
<pre><code>setwd(directory path)
df <- c()
for (x in list.files(pattern="*.cnv")) {
u<-read.table(x)
u$Filename = factor(x)
df <- rbind(df, u)
}
</code></pre>
<p>Now I am faced with a situation where there are several sub-directories with irregular names. Before I was telling R "move to this directory, look for all files with .cnv, then combine them into one dataframe". Now I need to tell R "move to this directory, look in this directory and all sub-directories for files with .cnv then combine them into a dataframe. </p>
<p>Any idea how I might accomplish within R?</p>

likes ["Jacob", "Alex"] // must be "Jacob and Alex like this"
likes ["Max", "John", "Mark"] // must be "Max, John and Mark like this"

How is this method using a parameter that is never given a value? : <p>I came across the .every() method today and found this example code to explain how it works:</p>
<pre><code>var ages = [32, 33, 16, 40];
function checkAdult(age) {
return age >= 18;
}
function myFunction() {
document.getElementById("demo").innerHTML = ages.every(checkAdult);
}
</code></pre>
<p>The result of <code>myFunction()</code> is <code>false</code>, and I understand what the method is doing (going through each value of the array and checking if the value is <code>>= 18</code>, but I don't understand how the <code>.every()</code> method is able to use the <code>age</code> parameter in its return statement without <code>age</code> being declared in the method call.</p>
<p>Does the method somehow automatically know that it should be referencing the index of the array it's looking at? That's the only explanation I can come up with, but I can't find any explanation of this online.</p>

Remove suffix after file type windows : I have a folder full of CSV files which get stored with a time stamp and an identifier after the file type, meaning windows does not recognise the files as CSVs (and any VBA code to access them won't recognise them either).
The file format is always: ABCDEFG.csv.20161205-071658
"ABCDEFG.csv" never changes.
How do I remove all characters after the second "."?

hi i need to Read a txt file and then use the first column data as a parameter to create a matrix (c#) : txt, this are the first 10 columns of 210 total,the numbers are saparated by spaces and only the first column is diferent, the other 210 columns are similar
210 7
15.26 14.84 0.871 5.763 3.312 2.221 5.22
14.88 14.57 0.8811 5.554 3.333 1.018 4.956

16.63 15.46 0.8747 6.053 3.465 2.04 5.877
i need to create a matrix using the first column data as a parameter 210 columns and 7 rows (this parameters could change like this 210 6 or 100 4) and then save the other columns in the matrix.
i had this code in c++ and i just need the matrix to continue so can you please help me

pandas: find percentile stats of a given column : <p>I have a pandas data frame my_df, where I can find the mean(), median(), mode() of a given column:</p>
<pre><code>my_df['field_A'].mean()
my_df['field_A'].median()
my_df['field_A'].mode()
</code></pre>
<p>I am wondering is it possible to find more detailed stats such as 90 percentile? Thanks!</p>

<blockquote>
<p>Are there only Onions on this Shish^D:</p>
<p><strong>new</strong> Skewer()?</p>
</blockquote>
<p>Answer is:</p>
<blockquote>
<p>true, because there is neither Lamb nor Tomato on <strong>new</strong> Skewer().</p>
</blockquote>
<p><a href="http://i.stack.imgur.com/nZuyv.png" rel="nofollow">definitions of classes</a></p>
<p>Skewer is a subclass of Shish^D, Onion is also a subclass of Shish^D, I don't understand why there are onions on <code>new Skewer()</code>, could someone explain this a bit further?</p>
