Puppeteer wait for all images to load then take screenshot : <p>I am using <a href="https://github.com/GoogleChrome/puppeteer" rel="noreferrer">Puppeteer</a> to try to take a screenshot of a website after all images have loaded but can't get it to work.</p>
<p>Here is the code I've got so far, I am using <a href="https://www.digg.com" rel="noreferrer">https://www.digg.com</a> as the example website:</p>
<pre><code>const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://www.digg.com/');
await page.setViewport({width: 1640, height: 800});
await page.evaluate(() => {
return Promise.resolve(window.scrollTo(0,document.body.scrollHeight));
});
await page.waitFor(1000);
await page.evaluate(() => {
var images = document.querySelectorAll('img');
function preLoad() {
var promises = [];
function loadImage(img) {
return new Promise(function(resolve,reject) {
if (img.complete) {
resolve(img)
}
img.onload = function() {
resolve(img);
};
img.onerror = function(e) {
resolve(img);
};
})
}
for (var i = 0; i < images.length; i++)
{
promises.push(loadImage(images[i]));
}
return Promise.all(promises);
}
return preLoad();
});
await page.screenshot({path: 'digg.png', fullPage: true});
browser.close();
})();

Use HttpClientFactory from .NET 4.6.2 : <p>I have a .NET 4.6.2 console application (using Simple Injector). I need to make calls to an HTTP service. Having run into issues using HttpClient directly, I'm trying to use HttpClientFactory ( <a href="https://github.com/aspnet/HttpClientFactory" rel="noreferrer">https://github.com/aspnet/HttpClientFactory</a> ) instead.</p>
<p>The project/library is .NET Standard 2.0 so it should?? work in .NET 4.6.2, but it uses stuff like IServiceCollection, which is in Core only.</p>
<p>So my question is can I use HttpClientFactory in a non-Core application.</p>

How do I validate the DI container in ASP.NET Core? : <p>In my <code>Startup</code> class I use the <code>ConfigureServices(IServiceCollection services)</code> method to set up my service container, using the built-in DI container from <code>Microsoft.Extensions.DependencyInjection</code>.</p>
<p>I want to validate the dependency graph in an unit test to check that all of the services can be constructed, so that I can fix any services missing during unit testing instead of having the app crash at runtime. In previous projects I've used Simple Injector, which has a <code>.Verify()</code> method for the container. But I haven't been able to find anything similar for ASP.NET Core.</p>
<p><strong>Is there any built-in (or at least recommended) way of verifying that the entire dependency graph can be constructed?</strong></p>
<p>(The dumbest way I can think of is something like this, but it will still fail because of the open generics that are injected by the framework itself):</p>
<pre><code>startup.ConfigureServices(serviceCollection);
var provider = serviceCollection.BuildServiceProvider();
foreach (var serviceDescriptor in serviceCollection)
{
provider.GetService(serviceDescriptor.ServiceType);
}
</code></pre>

How to terminate another appliation using c++/c#/vc++ gracefully? : I have an application running an infinite loop and performing some important functions in that loop. I need to provide the user with another application which would terminate the application with infinite loop. The problem is what if the user terminates the application when it is inside loop performing some operation. It would lead to inconsistent state. I tried kill() and TerminateProcess but they didn't help. Is there any way i could signal the application with infinite loop that complete your iteration and exit? I am open to solutuons in c#,cpp and vc++.

What database to choose from? : <p>Realm Database or MySQL or MongoDB or the standard Firebase. </p>
<p>I am curious why would anyone choose one over another. I am in a group project and one of the members in the group suggested that we should use Realm Database over Firebase. He tried to explain to me the reason but I was not able to comprehend. </p>
<p>What has your experience been like? Is one database more user-friendly over another?
Firebase seems to have very nice documentation. </p>

How to deal with values between methods and constructors : <p>Its rough right now, but I'm stuck because I can't find a way to access either digits (an array of integers (it has to be a private array, per the assignment rules)) or size. Is there a way to access constructor variables in methods within the same class?</p>
<p>I'm not sure what to try, as I'm still in the very basic stages (only a lesson or two in Java) and I don't know how to continue.</p>
<pre><code>public class Zillion {
private int[] digits;
String strdigits;
public Zillion(int size) {
int[] digits = new int[size];
}
public String toString() {
for(int x=0; x<digits.length; x++) {
strdigits += digits[x];
System.out.println(strdigits);
}
return(strdigits);
}
public static void main(String[] args) {
Zillion z = new Zillion(2);
System.out.println(z); // 00 2 points
}
</code></pre>
<p>}</p>
<p>Below are my errors; System.out.println(z) is supposed to output 00, but it seems the code gets trapped by a NullPointerException when I try to access digits.length in line 10.</p>
<pre><code>Exception in thread "main" java.lang.NullPointerException
at lab4_carl6188.Zillion.toString(Zillion.java:10)
at java.base/java.lang.String.valueOf(String.java:3042)

Run Angular2 as static app in browser without a server : <p>As I understand the Angular2 concept - it is transpiling TypeScript files to .js files. In principle, it should be possible to compile, package, and then run that Angular2 application as a static application from AWS S3 bucket, GitHub or whatever static source.</p>
<p>If I run Angular2 application on node server (with angular-cli "ng serve" command), it takes 500 MB of RAM on server - it's "Heey, common!" - is it really supposed to be that way! What's the benefit of this framework then against React, for example, which needs only a browser.</p>
<p>I can't seem to find anything useful on serving Angular2 application as a static compiled HTML+JS.</p>
<p>Maybe you can help me understand this, and solve?</p>
<p>Thanks a lot!</p>

When people upload videos on the site, I would like the video to have its own url like this: "localhost/example.com/string". For example, Youtube has a new url for each upload like this "<a href="https://www.youtube.com/watch?v=209fsloiwifo" rel="nofollow noreferrer">https://www.youtube.com/watch?v=209fsloiwifo</a>" Is there a way for me to create a new url for each new post in php?</p>

C++ Avoid passing variable to std::cout if variable is zero : Suppose I have a variable, `double x`, as a result of some calculations, which can have any value, including zero, and I need it passed to `std::cout`. How can I avoid printing `x` if its value is zero?
As an example, this will print `1+<value_of_x>` if `x`, else just `1`:
`std::cout << (x ? "1+" : "1") << x << '\n';`
Is there a way to make the same but for `x`? Something like the following nonsense:
`std::cout << (x ? ("1+" << x) : "1") << '\n';`
I should probably add that I am not advanced in C++.

How can I diff two branches in GitHub? : <p>I am just wondering if there is a way to simply diff two branches in GitHub? I know GitHub has capacity to do it because when we do code-reviews it does list out all the diffs nicely. I was just wondering if there is a way to do it without any code review to compare say Branch to Branch or Commit to Commit? So that when I push something to my remote branch and I want to see how my diffs are going to look like BEFORE it create a PR then it can be very helpful.</p>
<p>I can always be in console and do git diff but that is really not as nice and visually clear as how it shows up in web UI of GitHub. Any ideas?</p>

Mailgun Domain not found: abc.com : <p>I am trying to setup emails with my own website. Let's say the domain name is <code>abc.com</code>.</p>

<p>While setting up things with mailgun, I used <code>mg.abc.com</code> (as they said it would also let me email using the root domain). The verification step is done and I can send email using <code>contact@mg.abc.com</code>.</p>

Active Directory concurrent password policies : <p>I have an interesting problem for you.</p>
<p>Do you know of any method to set 2 concurrent password policies in AD ?</p>
<p>Here is the idea :</p>
<ul>
<li>Policy 1 : if password length between 8 and 14 char --> impose complexity rule</li>
<li>Policy 2 : if password length greater than 14 char --> no complexity rule</li>
</ul>
<p>As far as I know, by default, Windows will execute the policies sequentially.
Meaning, by default, Windows will override the first policy with the second, which is not what I'm looking for.</p>

Java: How to convert a list to HashMap (key being the list) in one line : <p>I have an arraylist of Strings:</p>
<pre><code>ArrayList<String> list = Arrays.asList("A", "B", "C", "D");
</code></pre>
<p>I would like to initialize a map <code>HashMap<String, List<Integer>></code> with the element of my list being the key and an empty list of integers being the value.</p>
<p>Of course there is a way to do it using a loop, but I wonder whether there is a way to do it in one line. After seeing the questions and answers in <a href="https://stackoverflow.com/questions/8261075/adding-multiple-entries-to-a-hashmap-at-once-in-one-statement">a similar question</a>, I am aware that it is doable by:</p>
<pre><code>HashMap<String, List<Integer>> bigMap = ImmutableMap.<String, List<Integer>>builder()
.put("A", new ArrayList<Integer>)
.put("B", new ArrayList<Integer>)
.put("C", new ArrayList<Integer>)
.put("D", new ArrayList<Integer>)
.build();
</code></pre>
<p>But that only applies to the scenario that the size of the list is small. How can I do it using stream, like the way mentioned in <a href="https://stackoverflow.com/questions/4138364/java-how-to-convert-list-to-map">another question</a>?</p>

SQL: Check if entry exists and return if it DOESN'T : I want to check if an entry exists in one table based on a value from a 2nd table, but if it DOESN'T exist then select the value from the 2nd table.
To explain, I have a table called `devices` and a table called `tests`. Each device in `devices` has a unique identifier (an integer). Each test in `tests` references the a device that the test was run on. Therefore, every `test` is associated with a `device`. However, not every `device` has been tested. Moreover, multiple tests could have been run on a single device.
So what I want to `SELECT` is all entries in `devices` that are NOT referenced by at least one entry in `tests`.

Export UIDocument with custom file package UTI : <p>I'm trying to export my <code>UIDocument</code> subclass with a <code>UIDocumentPickerViewController</code>. The subclass writes data to a <code>FileWrapper</code> and its UTI conforms to <code>com.apple.package</code>.</p>
<p>But the presented document picker shows <em>"Documents in iCloud Drive are not available because the iCloud Drive setting is disabled."</em></p>
<p><img src="https://i.stack.imgur.com/Rcne1.png" width="250"></p>
<p>The document is successfully written to the cache, as I can see from the exported container package.</p>

<p>When I change the document subclass and custom UTI to conform to a single file (e.g. <code>public.plain-text</code>), the document picker works fine and I can export the file. So the problem seems to be with the Document Type or Exported UTI.</p>
<p>Am I doing something wrong or is this a bug?</p>

Android Navigation Architecture Component - Get current visible fragment : <p>Before trying the Navigation component I used to manually do fragment transactions and used the fragment tag in order to fetch the current fragment.</p>
<p><code>val fragment:MyFragment = supportFragmentManager.findFragmentByTag(tag):MyFragment</code></p>
<p>Now in my main activity layout I have something like:</p>
<pre><code><fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/nav_host"
app:navGraph= "@navigation/nav_item"
android:name="androidx.navigation.fragment.NavHostFragment"
app:defaultNavHost= "true"

<p>How can I retrieve the current displayed fragment by the Navigation component?
Doing </p>
<p><code>supportFragmentManager.findFragmentById(R.id.nav_host)</code></p>
<p>returns a <code>NavHostFragment</code> and I want to retrieve my shown 'MyFragment`.</p>

Capture File and Folder Opening events in C# : I have a friend who live in HOSTEL, his roommates aren’t very trustworthy people, he said to me, to make something for him, so that He could know which files and folders were opened in his absence by his roommates? _(They have a mutual agreement of not opening someone personal folders)_ _(He is supposed to share PC and can’t hide or encrypt his personal folders)_
So I decided to go with C# because my friend is using Windows OS.
So The task is to make a Windows Form Application that will logs name and location of every file and folder opened by user _(in file or DB doesn’t matter)_ during the application running time.
I know there is a class of `FileSystemWatcher` but it only has four events of Changed, Created, Deleted & Renamed which I don’t need at all, It doesn’t matter if your is changing or deleting or creating or renaming something, all it does matter is which files & folders are opened by user ...?
If it could be done in Java I am also ready to give it a shot, just point me in the right direction !!

TypeScript within .cshtml Razor Files : <p>I am starting a new project using ASP.NET-MVC framework. I'd like to use TypeScript in this project in place of JavaScript. TypeScript is easily supported by Visual Studio but doesn't seem to be (fully) compatible with the .cshtml razor files. I'm able to create my classes within the .ts file and call those classes within my .cshtml file, the issue is when I pass in parameters to the object in the .cshtml file TypeSafety is ignored and the function is run as if a type were never defined.</p>
<p><strong>.ts file</strong></p>
<pre><code> export class SomeClass {
name: number;
constructor(public tName: number) {
this.name = tName;
}
public sayName() {
alert(this.name);
}
}
</code></pre>
<p><strong>.cshtml file</strong></p>
<pre><code>var instance = new SomeClass("Timmy");
instance.sayName();
</code></pre>
<p>As you can see, I am passing a string to the constructor even though I clearly defined the parameter to only accept numbers, but the TypeSafely is ignored and the TypeScript/JavaScript executes as if there is no issue.</p>
<p>Both file types were invented by Microsoft so I'm slightly surprised they aren't a little more friendly with each other. This isn't the end of the world, at least I am still able to use Object Oriented Programming, I'm just curious if anyone else has experienced this and can maybe give me a brief explanation. </p>

9 buttons are calling one function. I want to change value of button which called/invoked the function : There are 9 buttons in my page calling the same js function, I want to change the value of button which called the function to "abc". How to do it pls help..
I know I can use 9 different functions individually for 9 buttons, but that would be too lengthy.

Can't create Docker network : <p>I've been able to start my Docker application without a problem but suddenly I get this error:</p>
<blockquote>
<p>failed to parse pool request for address space "LocalDefault" pool ""
subpool "": could not find an available, non-overlapping IPv4 address
pool among the defaults to assign to the network</p>
</blockquote>
<p>I'm running Docker 1.12.6.</p>
<p>How do I fix this?</p>
