how to make sure a file's integrity in C# : <p>I am deploying a file along with a C# application. And I want to make sure that file is same as it was supplied otherwise the C# application will show error. Now, a file's creation and modification date can be changed after it is modified. Is there any checksum/hash etc. in C# to make sure file is not changed by user.</p>

WebSockets in Chrome and Firefox Disconnecting After One Minute of Inactivity : <p>I have found that WebSockets in Chrome and Firefox disconnect after exactly one minute of inactivity. Based on stuff I've seen online, I was all set to blame proxies or some server settings or something, but this does not happen in IE or Edge. It seems like if sockets are disconnected by the server after one minute of inactivity that would apply to IE and Edge just as much as Chrome and Firefox.</p>
<p>Does anyone know why this is? Is it documented anywhere? I know a possible way to stop it by pinging, but I'm more interested in why it's happening. The reason code given on disconnect is 1006, indicating that the browser closed the connection. No errors are thrown and the onerror event for the socket is not triggered.</p>
<p>This project was built at <a href="https://glitch.com/edit/#!/noiseless-helmet" rel="noreferrer">https://glitch.com/edit/#!/noiseless-helmet</a> where you can see and run everything. The client page is served here: <a href="https://noiseless-helmet.glitch.me/" rel="noreferrer">https://noiseless-helmet.glitch.me/</a></p>
<p>Here is my client page:</p>
<pre><code><div id="div">
</div>
<script>
let socket = new WebSocket("wss://noiseless-helmet.glitch.me/");
socket.onmessage = function(event) {
div.innerHTML += "<br>message " + new Date().toLocaleString() + " " + event.data;
};
socket.onopen = function (event) {
div.innerHTML += "<br>opened " + new Date().toLocaleString();
socket.send("Hey socket! " + new Date().toLocaleString());
};
socket.onclose = function(event) {
div.innerHTML += "<br>socket closed " + new Date().toLocaleString();
div.innerHTML += "<br>code: " + event.code;
div.innerHTML += "<br>reason: " + event.reason;
div.innerHTML += "<br>clean: " + event.wasClean;
};
socket.onerror = function(event) {
div.innerHTML += "<br>error: " + event.error;
};
</script>
</code></pre>
<p>And here is my Node.js server code:</p>
<pre><code>var express = require('express');
var app = express();
app.use(express.static('public'));
let server = require('http').createServer(),
WebSocketServer = require('ws').Server,
wss = new WebSocketServer({ server: server });
app.get("/", function (request, response) {
response.sendFile(__dirname + '/views/index.html');
});
let webSockets = [];
wss.on('connection', function connection(socket) {
webSockets.push(socket);
webSockets.forEach((w) => { w.send("A new socket connected"); });
socket.on('close', (code, reason) => {
console.log('closing socket');
console.log(code);
console.log(reason);
let i = webSockets.indexOf(socket);
webSockets.splice(i, 1);
});
});
server.on('request', app);
server.listen(process.env.PORT, function () {
console.log('Your app is listening on port ' + server.address().port);
});

Async OnActionExecuting in ASP.NET Core's ActionFilterAttribute : <p>ASP.NET Core's <code>ActionFilterAttribute</code> has these:</p>
<pre><code>public virtual void OnActionExecuting(ActionExecutingContext context);
public virtual void OnActionExecuted(ActionExecutedContext context);
public virtual Task OnActionExecutionAsync(ActionExecutingContext context, ActionExecutionDelegate next);
</code></pre>
<p>I need an async version of <code>OnActionExecuting</code>, which doesn't exist.</p>
<p>However I have a feeling that I can use <code>OnActionExecutionAsync</code> instead, as it also has an argument of <code>ActionExecutingContext</code>.</p>
<p>Am I correct that despite the name, they trigger at the same point in the process?</p>
<p>Also, what do I need to do with the <code>next</code> argument? Once I'm done with my stuff, do I simply need to call <code>await next()</code>?</p>
<p>Is that it? I'm unsure as I can't find docs for this.</p>

componentDidUpdate vs componentWillReceiveProps use case in react : <p>This is how we use <code>componentWillReceiveProps</code></p>
<pre><code>componentWillReceiveProps(nextProps) {
if(nextProps.myProp !== this.props.myProps) {
// nextProps.myProp has a different value than our current prop
}
}
</code></pre>
<p>It's very similar to <code>componentDidUpdate</code></p>
<pre><code>componentDidUpdate(prevProps) {
if(prevProps.myProps !== this.props.myProp) {
// this.props.myProp has a different value
// ...
}
}
</code></pre>
<p>I can see some differences, like if I do setState in componentDidUpdate, render will trigger twice, and the argument for componentWillReceiveProps is nextProps, while argument for <code>componentDidUpdate</code> is prevProp, but seriously I don't know when to use them. I often use <code>componentDidUpdate</code>, but with prevState, like change a dropdown state and call api</p>
<p>eg.</p>
<pre><code>componentDidUpdate(prevProps, prevState) {
if(prevState.seleted !== this.state.seleted) {
this.setState({ selected: something}, ()=> callAPI())
}
}

Is linking one project class to another project cause any performance or mermory issue in c# .Net? :
I have linked some of the classes from one project to another project by using the below codes. This code added in my csproject file.
<ItemGroup>
<Compile Include="..\..\OrignialFile\ClassName.cs">
<Link>Destination\ClassName.cs</Link>
</Compile>
</ItemGroup>
While running the application by adding these project files as reference i have faced some performance issue (i.e takes such long time for execution). Before linking i can able to do the same at minimal time. So i suspect linking classes could be reason for the performance issue. Is my suspection is correct, if it true please help me to resolve this issue?

How can i measure the usage of my android app? (e.g. in Play Console) : Is there a way to measure the usage (startups) of my android app?
In Play Console i only see the installations/deinstallations but not the startups etc.?
Well - i could implement a tracker on my own that access an interface on each startup - but i wonder if it's really necessary or if google provides that.
Thanks. | 0debug |

How to disable npm's progress bar : <p>As pointed out <a href="https://github.com/npm/npm/issues/11283" rel="noreferrer">here</a> the progress bar of npm slows down the whole installation progress significantly. The solution given is to disable it</p>
<pre><code>$> npm set progress=false && npm install
</code></pre>
<p>The question I have, is it possible inside a project to set something (in package.json for example) such that I can omit <code>progress=false</code> on the command line and simply can do <code>$> npm install</code> and obtain the same result as above?</p>

Why hash maps in Java 8 use binary tree instead of linked list? : <p>I recently came to know that in Java 8 hash maps uses binary tree instead of linked list and hash code is used as the branching factor.I understand that in case of high collision the lookup is reduced to O(log n) from O(n) by using binary trees.My question is what good does it really do as the amortized time complexity is still O(1) and maybe if you force to store all the entries in the same bucket by providing the same hash code for all keys we can see a significant time difference but no one in their right minds would do that.</p>
<p>Binary tree also uses more space than singly linked list as it stores both left and right nodes.Why increase the space complexity when there is absolutely no improvement in time complexity except for some spurious test cases.</p>

spring-configuration-metadata.json file is not generated in IntelliJ Idea for Kotlin @ConfigurationProperties class : <p>I'm trying to generate spring-configuration-metadata.json file for my Spring Boot based project.

private String hello;
public String getHello() {
return hello;
}
public void setHello(String hello) {
this.hello = hello;

<pre><code>@ConfigurationProperties("myprops")
class MyProps {
var hello: String? = null

<p>AFAIK Kotlin generates the same class with constructor, getters and setters and should act as regular Java bean.</p>

Whats best way to have indexing in mysql : Need a support! Seems like small question, but i am puzzled.
I have a table with around 25 columns. The table will contains many lakhs of rows at any point of time.
I want to run below query continously in loop.
SELECT recordfile
FROM MYTABLE
WHERE duration = '0'
AND attempt < max_attempt
AND thread =1
ORDER BY id ASC
It looks like query is taking more time(0.0150 secs on avg) Please help to put proper indexing or any other method, to make the query optimally quick.

How to include the end date in a DatePeriod? : <p>I am trying to get a Date range for all workdays this week. I have written the following code to do so.</p>
<h3>Code</h3>
<pre><code>$begin = new DateTime('monday this week'); 2016-07-04
$end = clone $begin;
$end->modify('next friday'); // 2016-07-08
$interval = new DateInterval('P1D');
$daterange = new DatePeriod($begin, $interval, $end);
foreach($daterange as $date) {
echo $date->format('Y-m-d')."<br />";
}
</code></pre>
<h3>Output</h3>
<ul>
<li>2016-07-04</li>
<li>2016-07-05</li>
<li>2016-07-06</li>
<li>2016-07-07</li>
</ul>
<p>In the output friday is missing. I can fix this by doing <code>$end->modify('next saturday')</code> but I was wondering why the last day of a <code>DatePeriod</code> is not included in the range.</p>

C++ malloc(): memory corruption : <p>I am currently going through a fibonacci practice problem on hackerrank and am having a malloc memory corruption error. This is the link to the problem I am doing:</p>

<p>Input is 0-10, each number separated by a new line.
For each input, the value at that point in the sequence is printed. It works for small inputs, but after 6 it gets the malloc error. It doesn't seem that the size of the sequence is an issue either, just how many are done in succession.</p>
<pre><code>#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;
vector<int> bigFib(1);
int main() {
/* Enter your code here. Read input from STDIN. Print output to STDOUT */
int x;
while(cin >> x){
if(bigFib.size()-1 >= x){
cout << bigFib[x] << endl;
}
else{
vector<int> fib(x);
fib[0] = 0;
fib[1] = 1;
for(int j = 2; j <= x; j++){
fib[j] = fib[j-1] + fib[j-2];
}
bigFib = fib;
cout << fib[x] << endl;

return 0;

How to implement a debounce time in keyup event in Angular 6 : <p>I create an Angular app that search students from API. It works fine but it calls API every time an input value is changed. I've done a research that I need something called debounce ,but I don't know how to implement this in my app.</p>
<p><strong>App.component.html</strong></p>
<pre><code> <div class="container">

<a href="https://i.stack.imgur.com/mt9mt.png" rel="noreferrer"><img src="https://i.stack.imgur.com/mt9mt.png" alt="Screenshot"></a></p>
<p>I've tried something like this but it's error
<strong>Property debounceTime does not exist on type Subject<{}></strong></p>
<pre><code> mySubject = new Subject();
constructor(private http:Http) {
this.mySubject
.debounceTime(5000)
.subscribe(val => {
//do what you want
});
}
</code></pre>
<p>and this's also not work. <strong>Property 'fromEvent' does not exist on type 'typeof Observable'</strong> </p>
<pre><code> Observable.fromEvent<KeyboardEvent>(this.getNativeElement(this.term), 'keyup')
</code></pre>
<p>So, what's the correct way to implement this ? </p>
<p>Thank you.</p>

parse json array with javascript : I have a mySQL database with a table of Latitudes and longitudes with associated data. I'm trying to create a Google Map and want to parse the JSON string using Javascript. I have looked here and on youtube and I don't know how to solve what I'm doing wrong.

php method argument type hinting with question mark (?type) : <p>I just felt on pieces of php (symfony/laravel) code using question mark in method type hints :</p>
<pre><code>public function functionName(?int $arg = 0)
</code></pre>
<p>In other occasions the <strong>?type</strong> was not the last one, but I did not find any of these with no default yet.</p>
<p>Problem is, I cannot find any information about this, and I checked :</p>
<ul>
<li>here : <a href="http://php.net/manual/en/migration70.new-features.php" rel="noreferrer">http://php.net/manual/en/migration70.new-features.php</a></li>
<li>and here : <a href="http://php.net/manual/en/migration71.new-features.php" rel="noreferrer">http://php.net/manual/en/migration71.new-features.php</a></li>
<li>and here : <a href="http://php.net/manual/en/functions.arguments.php" rel="noreferrer">http://php.net/manual/en/functions.arguments.php</a></li>
</ul>
<p>And same with 7.2, but since the code only requires 7.1, it seems rather normal.</p>
<p>I also googled, and searched here, but either this is not documented or the question marks topic is defeating search engines.</p>
<p>So I feel a little dumb now, and I would really appreciate if someone could enlighten me on the signification of this question mark in method signatures arguments.</p>

}
task.resume()
return httpStatusCode
}
</code></pre>
<p>I need to be able to call this and at the same time check the return value as it is the http status code, it will let me know if the call was successful or not.</p>
<p>Problem is because it's in a dataTask I can't access the responses status code here</p>
<pre><code>var httpStatusCode:Int = (httpStatus?.statusCode)!
</code></pre>
<p>Because the task doesn't start until Task.Resume() is called and the task is asynchronous so it will never work.</p>

Creation of GSI taking long time : <p>I have a table with close to 2 billion rows already created in DynamoDB.</p>
<p>Due to a query requirement, I had to create a Global Secondary Index(GSI) in it. The process of GSI creation started 36 hours ago but still isn't completed. Portal shows Item Count to be around 100 million. So long way to go.</p>
<p>Questions:</p>
<ol>
<li>Why does it take such a long time when sufficient WCU and RCU are
alotted( 30k in fact ).</li>
<li>GSI partition key I've used is something whose values are repetitive, could that be the reason why GSI creation is taking more time (ideal scenario is that we select a partition key which doesn't repeat for items to span across multiple partitions).</li>
<li>Is there a way to abort the creation of GSI while the process is on? it doesn't allow through AWS console.</li>
</ol>
<p>Thanks.</p>

Add/remove class to element with delay if mouse is still over : I am opening my submenu with adding a class("reveal") to it's parent. What i want to achieve is when i hover over a parent, if no "active" hover is going on, to open the submenu immediately, but if a submenu is already shown, then wait 1second before it opens a new one.
I want this because of "bad" mouse movement for it to wait in case the mouse leaves the submenu/parent to see if it re-enters in 1second.
I know there are a bunch of similar threads, but i already did my attempt and can't se eright now what im doing wrong:
$('.menu > li').hover(function(){
var ele = $(this);
if($('.menu li.reveal').length > 0){
var t = setTimeout(function(){
if( ele.hover() ){
$('.menu li.reveal').removeClass('reveal');
ele.addClass('reveal');
}
},1000);
}
else{
ele.addClass('reveal');
}

Python changing elements in array while it only appears once in shell :
Didn't know how to correctly write the title, so i will try to explain it here. I am making a game, similar to tic tac toe. The play field is 4x4 and i am saving it as an array. I want to make changes in the array during the game, but it will not print out the array each time, rather it makes changes statically.
Lets say at the beginning i print out the whole field and under it the user is asked to type a position. He gives it and the changes are being done in the first printed playfield, without calling it again in the shell. Kinda sloppy explanation, sorry about that.
play_field = [[0,0,0,0],[0,0,0,0],[0,0,0,0],[0,0,0,0]]
def print_playfield():
for rows in play_field:
print(*['{:<4}'.format(each) for each in rows])
This is the function, which will display the playfield.I've done it with tkinter already, wanna try it without. | 0debug |

Is this a possible bug in .Net Native compilation and optimization? : <p>I discovered an issue with (what might be) over-optimization in <code>.Net Native</code> and <code>structs</code>. I'm not sure if the compiler is too aggressive, or I'm too blind to see what I've done wrong. </p>
<p>To reproduce this, follow these steps:</p>
<p><strong>Step 1</strong>: Create a new Blank Universal (win10) app in <em>Visual Studio 2015 Update 2</em> targeting build 10586 with a min build of 10240. Call the project <em>NativeBug</em> so we have the same namespace.</p>
<p><strong>Step 2</strong>: Open <code>MainPage.xaml</code> and insert this label</p>
<pre><code><Page x:Class="NativeBug.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

mc:Ignorable="d">
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<!-- INSERT THIS LABEL -->
<TextBlock x:Name="_Label" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
</Page>
</code></pre>
<p><strong>Step 3</strong>: Copy/paste the following into <code>MainPage.xaml.cs</code></p>
<pre><code>using System;
using System.Collections.Generic;

<p><strong>Step 4</strong>: Run the application in <code>Debug</code> <code>x64</code>. You should see this label:</p>
<blockquote>
<p>42.5 , 42.5 => 107.5 , 107.5</p>
</blockquote>
<p><strong>Step 5</strong>: Run the application in <code>Release</code> <code>x64</code>. You should see this label:</p>
<blockquote>
<p>-7.5 , -7.5 => 7.5, 7.5</p>
</blockquote>
<p><strong>Step 6</strong>: Uncomment <code>line 45</code> in <code>MainPage.xaml.cs</code> and repeat step 5. Now you see the original label</p>
<blockquote>
<p>42.5 , 42.5 => 107.5 , 107.5</p>
</blockquote>
<hr>
<p>By commenting out <code>line 45</code>, the code will use <code>Rectangle2D.Inflate2(...)</code> which is exactly the same as <code>Rectangle2D.Inflate1(...)</code> except it creates a local copy of the computations before sending them to the constructor of <code>Rectangle2D</code>. In debug mode, these two function exactly the same. In release however, something is getting optimized out.</p>
<p>This was a nasty bug in our app. The code you see here was stripped from a much larger library and I'm afraid there might be more. Before I report this to Microsoft, I would appreciate it if you could take a look and let me know why <code>Inflate1</code> doesn't work in release mode. Why do we have to create local copies?</p>

How to call conditionally B::f only if derived from B in C++11? : <p>In case when static polymorphism is used, especially in templates (e.g. with policy/strategy pattern), it may be required to call base function member, but you don't know was instantiated class actually derived from this base or not.</p>
<p>This easily can be solved with old good C++ ellipsis overload trick:</p>
<pre><code>#include <iostream>
template <class I>
struct if_derived_from
{
template <void (I::*f)()>
static void call(I& x) { (x.*f)(); }
static void call(...) { }
};
struct A { void reset() { std::cout << "reset A" << std::endl; } };
struct B { void reset() { std::cout << "reset B" << std::endl; } };
struct C { void reset() { std::cout << "reset C" << std::endl; } };
struct E: C { void reset() { std::cout << "reset E" << std::endl; } };
struct D: E {};
struct X: A, D {};
int main()
{
X x;
if_derived_from<A>::call<&A::reset>(x);
if_derived_from<B>::call<&B::reset>(x);
if_derived_from<C>::call<&C::reset>(x);
if_derived_from<E>::call<&E::reset>(x);
return 0;
}
</code></pre>
<p>The question is:</p>
<ul>
<li>Is there any better <em>simple</em> way (e.g. SFINAE doesn't look so) to achieve same result in C++11/C++14?</li>
<li>Would empty call of ellipsis parameter function be elided by optimizing compiler? Hope such case is not special against any "normal" function.</li>
</ul>

std::bit_cast with std::array : <p>In his recent talk <a href="https://www.youtube.com/watch?v=_qzMpk-22cc" rel="noreferrer">“Type punning in modern C++”</a> Timur Doumler <a href="https://youtu.be/_qzMpk-22cc?t=2755" rel="noreferrer">said</a> that <code>std::bit_cast</code> cannot be used to bit cast a <code>float</code> into an <code>unsigned char[4]</code> because C-style arrays cannot be returned from a function. We should either use <code>std::memcpy</code> or wait until C++23 (or later) when something like <code>reinterpret_cast<unsigned char*>(&f)[i]</code> will become well defined.</p>
<p>In C++20, can we use an <code>std::array</code> with <code>std::bit_cast</code>,</p>
<pre><code>float f = /* some value */;
auto bits = std::bit_cast<std::array<unsigned char, sizeof(float)>>(f);
</code></pre>
<p>instead of a C-style array to get bytes of a <code>float</code>?</p>

Formatting a date - Rails : <p>I have a variable containing a date in this form: (2018-03-21 18:49:49 UTC)
and I would like to display in this form: (day / month / year) but I can not find a solution. Do you have an idea ? Thank you !</p>
| 0debug |
I need to create a Perl 5 regex statement that will parse 2 separate dates from a string : <p>The string is of the following format:<br>
"Unwanted words and spaces" Date1 "and" Date2. Date 2 is at the very end of the whole string. How can I go about writing this? The date formats are of the form m/dd/yyyy.</p>
<p>Thanks,
Ryan</p>

Text Overlay Image with Darkened Opacity React Native : <p>I am attempting to overlay a title over an image - with the image darkened with a lower opacity. However, the opacity effect is changing the overlaying text as well - making it dim. Any fix to this? Here is what is looks like:</p>

React/RCTEventEmitter.h file not found : <p>I am trying to implement PushNotificationIOS with a detached Expo app. I am running SDK 21.0.0 (React Native 0.48).</p>
<p>I am getting <code>React/RCTEventEmitter file not found</code> </p>
<p>I have completed the following steps:</p>
<ul>
<li>Open my <code>.xcworkspace</code> project</li>
<li>Drag the <code>RCTPushNotification.xcodeproj</code> into my Libraries folder</li>
<li>Added <code>libRCTPushNotification.a</code> into <code>App > Build Phases > Link Binary With Libraries</code></li>
<li>Added <code>$(SRCROOT)/../node_modules/react-native/Libraries</code> under Header Search Paths - I also tried without the <code>/../</code>. I have a bunch of Pods in the Header Search Paths list too.</li>
</ul>
<p>I then added the following into <code>AppDelegate.m</code> but when I click through to the file (⌘ + click), I get a question mark.</p>
<pre><code>#import <React/RCTPushNotificationManager.h>
</code></pre>
<p>If I change it to the below, it works, I can click through</p>
<pre><code>#import "RCTPushNotificationManager.h"
</code></pre>
<p><strong>However, this is my problem</strong></p>
<p>When I clean and build my project, I get the below error in <code>RCTPushNotificationManager.h</code> to say:</p>
<pre><code>'React/RCTEventEmitter.h' file not found
</code></pre>

Azure Cosmos DB Update Pattern : <p>I have recently started using Cosmos DB for a project and I am running into a few design issues. Coming from a SQL background, I understand that related data should be nested within documents on a NoSQL DB. This does mean that documents can become quite large though. </p>
<p>Since partial updates are not supported, what is the best design pattern to implement when you want to update a single property on a document? </p>
<p>Should I be reading the entire document server side, updating the value and writing the document back immeadiately in order to perform an update? This seems problematic if the documents are large which they inevitably would be if all your data is nested.</p>
<p>If I take the approach of making many smaller documents and infer relationships based on IDs I think this would solve the read/write immeadiately for updates concern but it feels like I am going against the concept of a NoSQL and in essence I am building a relational DB.</p>
<p>Thanks</p>
