Handle "Loading chunk failed" errors with Lazy-loading/Code-splitting : <p>We are developing a Vue.js application based on Vue CLI 3 with Vue Router and Webpack. The <a href="https://router.vuejs.org/guide/advanced/lazy-loading.html" rel="noreferrer">routes are lazy-loaded</a> and the <a href="https://webpack.js.org/guides/caching/" rel="noreferrer">chunk file names contain a hash</a> for cache busting. In general, everything is working fine.</p>
<p>However, there is a problem during the deployment. Steps to reproduce are the following.</p>
<ul>
<li>User opens the application (let's assume route "/"), thus the main chunk file is loaded.</li>
<li>We change something in the application and deploy a new version.
<ul>
<li>Old chunk files are removed</li>
<li>New chunk files are being added (i.e. hashes in the chunk file names change)</li>
</ul></li>
<li>User clicks a link to another route (e.g. "/foo")
<ul>
<li>An error occurs as the application tries to load a chunk file that has been renamed: <code>Error: "Loading CSS chunk foo failed.
(/assets/css/foo.abc123.css)"</code> (this might be CSS or JavaScript)</li>
</ul></li>
</ul>
<p><strong>What is the best way to avoid errors like this?</strong></p>
<ul>
<li><p>One approach that should work is just to retain old chunk files and delete them at a later time. That, however, complicates the deployment of new versions as you need to keep track of old versions and always also deploy the old chunk files with the new version.</p></li>
<li><p>Another (naive) approach is to just reload as soon as such an error is detected (e.g. <a href="https://blog.francium.tech/vue-lazy-routes-loading-chunk-failed-9ee407bbd58" rel="noreferrer">Vue Lazy Routes & loading chunk failed</a>). It somewhat works, but it reloads the <em>old</em> route, not the <em>new</em> one. But at least it ensure that consecutive route changes work again.</p></li>
</ul>
<p>Any other ideas? Maybe there is something in webpack that could fix this?</p>

unexpected output in recursive function - c++ : I am trying to find the output for fun(5). But I am getting wrong answer, don't know why. My doubt is for n =5 for instance, it would return fun(3) + 3. After that would the return fun(4) + x work or the function fun will be called again?
int fun(int n)
{
static int x = 0;
if (n<=0) return 1;
if (n>3)
{
x = n;
return fun(n-2) + 3;

Why is the compiler-generated enumerator for "yield" not a struct? : <p>The <a href="http://csharpindepth.com/Articles/Chapter6/IteratorBlockImplementation.aspx">compiler-generated implementation</a> of <code>IEnumerator</code> / <code>IEnumerable</code> for <code>yield</code> methods and getters seems to be a class, and is therefore allocated on the heap. However, other .NET types such as <code>List<T></code> specifically return <code>struct</code> enumerators to avoid useless memory allocation. From a quick overview of the <em>C# In Depth</em> post, I see no reason why that couldn't also be the case here. </p>
<p>Am I missing something?</p>

Avoid for blindly declaring variables in perl : my $scalarVar = ""; my $scalarVar = ''; my $scalarVar = (); my $scalarVar;
my @arrayVar = ""; my @arrayVar = ''; my @arrayVar = (); my @arrayVar;
my %hashVar = ""; my %hashVar = ''; my %hashVar = (); my $hashVar;
Please provide a sample and explanation about this to learn proper declaration of the variables. And it would be appreciate if someone can?

isInitialized property for lateinit isn't working in companion object : <p>I have a singleton class which i have implemented it in java fashion :</p>
<pre><code>companion object {
@Volatile private lateinit var instance: TrapBridge
fun bridge(): TrapBridge {
if (!this::instance.isInitialized) {
synchronized(this) {
if (!this::instance.isInitialized) {
instance = TrapBridge()
}
}
}
return instance
}
}
</code></pre>
<p>now the problem is i can't use <code>isInitialized</code> property because it throws <code>NoSuchFieldError</code> exception :</p>
<pre><code>java.lang.NoSuchFieldError: No field instance of type Lcom/sample/trap/model/TrapBridge; in class Lcom/sample/trap/model/TrapBridge$Companion; or its superclasses (declaration of 'com.sample.trap.model.TrapBridge$Companion' appears in /data/app/com.sample.trapsample-L9D8b2vxEQfiSg9Qep_eNw==/base.apk)
</code></pre>
<p>and i think it's because <code>instance</code> is class variable and not instance variable so i can't reference it with <code>this</code> keyword :/</p>
<p>also i can't check if it's null because it throws <code>UninitializedPropertyAccessException</code> :</p>
<pre><code>lateinit property instance has not been initialized

Why sampling matrix row is very slow? : <p>I tried to do some bootstrapping and calculate <code>colMeans</code>, naturally I chose matrix to store data, however, it is very slow in sampling:</p>
<pre><code>m[sample(n,replace=TRUE),]
</code></pre>
<p>It turns out <code>data.table</code> is the fastest.</p>
<pre><code>require(microbenchmark)
require(data.table)
n = 2000
nc = 8000
m = matrix(1:(n*nc) ,nrow = n)
DF = as.data.frame(m)
DT = as.data.table(m)
s=sample(n, replace=TRUE)
microbenchmark(m[s,], DF[s,],DT[s,])
# Unit: milliseconds
# expr min lq mean median uq max neval
# m[s, ] 371.9271 402.3542 421.7907 420.8446 437.8251 506.1788 100

CMS or Framework for my website? : <p>I'm a programmer and for a couple of days I was asking myself: Should I use a CMS or a Framework to build my website?</p>
<p>I've learn Laravel (a PHP framework) that I am pretty skilled with it. This said, I tried last week to build a website using a CMS (Wordpress and Drupal) but OH MY I feel like there's no customization possible compared to a framework. I feel like you have some things preset that you can customize and that's it. So I wonder what to take to do a website that will be used to present a company's product and services.</p>
<p>Thanks for all the responses! Share your experience programers ;)</p>

Why output differs if i erase "else" from the function? : <p>I am trying to write a GCD function to calculate gcd of two integers using euclids algorithm. In the function if i erase "else" it outputs 3 which is incorrect . But if i use "else" it outputs 1 which is the correct output. i assume if i don't use "else" the function is still correct. Why am i getting two different outputs.</p>
<p>Here is my code, </p>
<pre><code> #include <iostream>
using namespace std;
int euclidGcd(int x , int y){
if(x%y!=0)
euclidGcd(y , x%y );
else
return y;
}
int main(){
cout<<euclidGcd(2,3)<<"\n";
return 0;

How do i keep the header cell moving with the tableview cells in Swift 2.0 : <p>I am trying to create a tableview which starts the header in the middle of the tableview and then can be scrolled up with the added tableView Cells to the top then stops, and then the tableview cells can just scroll "under" it. I got the header to be in the middle of the tableview, but the tableView Cells just scroll on top of it, and the header doesnt really scroll to the top. it just stay where it is. I want to be able to let the header move as you scroll the list, and then stops when it reaches the top of the list, and then its just the tableView Cells that are moving afterwards.</p>

<pre><code>public function user_get_endpoint(Request $request){
$request = $request->toArray();
return UserModel::where($request)->get()->toArray();
}
</code></pre>
<p>The above will currently break since the <code>$request</code> object contains a property called <code>api_token</code> which does not exist in the <code>user</code> table. I am using the <code>api_token</code> in a middleware to check for authentication.</p>
<p>I can manually unset the <code>api_token</code> property in each of my API functions by using <code>unset($request['api_token']</code>, but I'd like to avoid that if possible.</p>
<p>Is there anyway to do this application wide or at a class or controller level?</p>

Is JAX-RS built on top of Servlet API? How? : <p>I've been reading that the JAX-RS is built on top of servlets. Is this literally true, or it just mean that it is a higher level component? If it is, how does that work? Does JAX-RS create a servlet which parses the request and manually initializes <code>@Path</code> annotated classes and passes the modified parameters to them? The JSR does not seem to specify this, and none of the books that mention it go into any details.</p>
<p>note: I don't have trouble deploying JAX or servlets, I am just curious about the details, as it would provide a better understanding of how the web container works.</p>

Combine search engine and machine learning : <p>I'm pretty new on search engines and pretty newbie on machine learning. But I wanted to know if there is a way to combine functionalities of search engines like elasticsearch or Apache Solr and machine learning project like Apache Mahout, H2O or PredictionIO.</p>
<p>For exemple, if you work on a travel website where you can search for a destination. You start type "au", so the first suggestions are "AUstria", "AUstralia", "mAUrice island", "mAUritania"... etc... This is typically what elasticsearch can do.</p>
<p>But you know that this user has already travelled on Mauritania three times, so you want that Mauritania goes on the first place of suggestions. And I guess that's typically what machine learning can do.</p>
<p>Is there bridges between this two type of technologies ? Can machine learning ensure the work of search engine efficiently ?</p>
<p>I'm open to all answers, regardless of the technologies used. If you have ever experienced this type of problems, my ears are wide open :-)</p>
<p>Thank you</p>

How to read txt file and save as a single string in java in order to split it by a certain character : <p>I'm new to to java language & am finding trouble finding to:</p>
<pre><code>1. read a txt file
2. save entire txt file as single string
3. once I have the txt file content as a string, break the string (by a certain character such as a new line) into an array of strings that I can work with.
</code></pre>
<p>If you may include the import statements that are required, that would be helpful as well as a new java programmer.</p>
<p>I was working with the <code>BufferedReader</code> but I believe that only gives me the current line to work with.</p>
<p>I did see that <code>BufferedReader</code> had a <code>lines()</code> method which returns a stream of <code>Stream<String></code>.</p>

Where can I download Java Mission Control(7) (OpenJDK11 or higher)? : <p>Java Mission Control(JMC) was announced to be handed over from Oracle to the open source community from JDK 11 onwards.
However JMC is not bundled with the <a href="https://jdk.java.net/11/" rel="noreferrer">OpenJDK11 releases</a>.</p>
<p>I read that JMC will be provided as separate <a href="https://jdk.java.net/jmc/" rel="noreferrer">download here</a>, but there are no builds to download.
Also Oracle no longer provides a download on <a href="https://www.oracle.com/technetwork/java/javaseproducts/mission-control/java-mission-control-1998576.html" rel="noreferrer">their page about JMC</a>.
And I can no longer find it in the <a href="https://www.oracle.com/technetwork/java/javase/downloads/index.html" rel="noreferrer">Oracle JDK</a>.</p>
<p>The source is mirrored on <a href="https://github.com/JDKMissionControl/jmc" rel="noreferrer">GitHub</a> but there are also no build releases to download.</p>

<p>However, the output on the html page is:
'Hello World' on one line

How can I determine which server I'm connected to? : I'm a rookie so I'm not really acquainted with how this really works. I've downloaded SQL Server 2016 and once I log onto the Management Studio, it asks me to connect to a particular server. Now I've no idea which server I'm connected to. I've tried everything. Turned the firewall off, used cmd commands, (tells me that my access has been denied), registered a new server from within the studio (but I feel as if I'm not connected to any as nothing shows up) I'm really confused | 0debug |

Would you prefer a public or a private Blockchain for managing identities and the authentification in organisations? : <p>I am working on a blockchain implementation and I'm stucked for weeks now at the decision whether I should use a public or a private Blockchain. It's so difficult to decide. I want to manage the identities across organisations (organisations which working together) in one blockchain so that they can authenticate themselfs with just the one and same identifier on every web service (web services across the organizations).
My first idea was to use a private one because personal data should be private. But at one side if i use the private i would loose the benefits of the original blockchain technology. Also if i use a private i would have again a centralization because someone must manage the access to it? so it would be like a normal database? what would be the benefit then? on the other side if i use a public blockchain i cant control the users who have got access to it and everybody could see the personal data of each employee. </p>
<p>What would you prefer? And also which framework is the best for a quick prototype implementation? I'm thinking about using hyperledger. I'm greatful for every opinion/recommendation</p>

Cannot get histogram to show separated bins with vertical lines : <p>Annoying strange problem and I have not been able to find a solution on this site yet (although the question has popped up)</p>
<p>I am trying to make a histogram where the bins have the 'bar style' where vertical lines separate each bin but no matter what I change the histtype constructor to I get a step filled histogram. </p>
<p>Here is my code. Note I am using jupyter notebook installed via anaconda with python version 2.7.6</p>
<pre><code>import numpy as np
import matplotlib.pyplot as plt
x = np.random.rand((100))
bins = np.linspace(0, 2, 40)
plt.title('Relative Amplitude',fontsize=30)
plt.xlabel('Random Histogram')
plt.ylabel('Frequency',fontsize=30)
plt.hist(x, bins, alpha=0.5, histtype='bar')
plt.legend(loc='upper right',fontsize=30)
plt.xticks(fontsize = 20)
plt.yticks(fontsize = 20)
plt.show()
</code></pre>
<p>Thats it and I get a step filled diagram with no vertical lines separating the bars. What is annoying is that I didn't have this problem awhile ago, something clearly has changed and I don't know what.I have tried histype='barstacked' as well. Thank you kindly for your help</p>

Error checking TLS connection: Error checking and/or regenerating the certs : <p>After I restarted my windows i cannot connect to docker machine running in Oracle Virtual Box.
When i start Docker QuickStart Terminal every thing looks fine, it's coming up OK and it gives me this message:</p>
<pre><code>docker is configured to use the default machine with IP 192.168.99.100

</code></pre>
<p>and:</p>
<pre><code>λ docker images
An error occurred trying to connect: Get http://localhost:2375/v1.21/images/json: dial tcp 127.0.0.1:2375: ConnectEx tcp: No connection could be made because the target machine actively refused it.
</code></pre>
<p>also when i try to reinitialize my env., i get:</p>
<pre><code>λ docker-machine env default

You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'.
Be advised that this will trigger a Docker daemon restart which will stop running containers.

C++ I'm confused about declaring and using characters - for instance in this sscanf example : The following example works fine:
char rc[20]="1,150";
char command[1];
int data1 = 0;
int data2 = 0;
int data3 = 0;
int count = sscanf(rc, "%c,%d,%d,%d", command, &data1, &data2, &data3);
It gives:
count = 2; command[0] = 1; data1 = 150
But I don't know how to make this work if command is defined as:
char command; or char * command.

<p>I am really unsure why this is happening maybe it is something wrong with my manifests but I doubt it because the manifest was autogenerated. Please help I can't find the answer online because it seems like I followed everything online correctly this is the last place I came to for help I am so frustrated right now!</p>

How to get the url parameters in the same order as they are sent? (Java) : I have a use case in which multiple parameters are to be sent from a web page to servlet.
The name given to the parameters are in alphanumeric form, for example: 01h, 02h... etc.
I had used different Java functions such as Collections.sort() etc., but when there are more than 10 parameters the values are misplaced.
For example, the 10th parameter will have the name as 10h, thus after retrieving the parameters using Collections.sort(), the order becomes 01h, 10h, 02h...
Instead, it should be 01h, 02h, 03h, .... , 10h
Please advise. | 0debug |

<p>Obviously the backend is the same and it's covered by an aws certificate created by aws certificate manager. I think the problem is not the certificate because I think it is compliant to the new apple's certificates policy but I can't understand where the problem is.</p>

Add HTML breaker with PHP if statement : I have a PHP loop listing results from a database:
foreach($_SESSION['all'] as $result) {
echo $result;
}
What I have done is write an if statement in PHP so that every time 4 results have been outputted, execute a line of code. In order to do this I have declared '`$i = 0;`' outside of this loop and then inside the loop I have '`$i++;`'. I then say:
if ($i %4 == 0) {
//execute code inside this if statement
}
I then put a breaker inside this loop so that every 4 results, there would be a breaker ('`<br />`'). It looks like this:
if ($i %4 == 0){
echo "<br />";
echo $i;
}
When I look at the source code of the site the '`<br />`' is there but it doesn't move the rest of the information to another line. When I add a different line of code it shows, for example, if I print '`<p>Hello</p>`', it outputs 'Hello'. It just seems to be the '`<br />`' that doesn't work. This results in all the results after the first 4 being off the end of the screen.
Here is the whole page and a screenshot of the output:
<?php
session_start();
?>

How does WorkManager schedule GET requests to REST API? : <p>I've had a look at the codelab for WorkManager plus some examples on here, but everything in code I have seen is either related to doing work locally on the device or work uploading to the server, not downloading data and responding to the data received. In the developer guidelines it even says, "For example, an app might need to download new resources from the network from time to time," so I thought it would be perfect for this task. My question is if WorkManager can handle the following scenario and if not, what is the proper tool for handling it:</p>
<ol>
<li>Schedule a job that runs once a day in background</li>
<li>The job is to do a data fetch from the REST API (and post it to a LiveData object if possible).</li>
<li>When the data returns, check that it is newer than local data.</li>
<li>Notify the user that new data is available.</li>
</ol>
<p>My worker class looks something like this:</p>
<pre><code>public class MyWorker extends Worker {
@NonNull
@Override
public WorkerResult doWork() {
lookForNewData();
return WorkerResult.SUCCESS;
}
public void lookForNewData() {
MutableLiveData<MyObject> liveData = new MutableLiveData<>();
liveData.observe(lifeCycleOwner, results -> {
notifyOnNewData(results);
})
APILayer.getInstance().fetchData(searchParams, liveData)
}
</code></pre>
<p>My issue is of course that the LiveData object can't observe because there is no activity or fragment that can be its LifecycleOwner. But even if I used a callback from the API to respond to the data arriving, my worker would already have posted that it was successful and it probably would not proceed with the callback, right? So I kind of know this approach is totally wrong, but I can't see any code for getting data with WorkManager</p>
<p>Please help with a proper solution and some example code or some links, either with WorkManager if it can handle this kind of work or something else if it is more appropriate.</p>

How to be able to set up breakpoints correctly when using VS Code to debug a TypeScript app run using ts-node in a Docker container? : <p>Our app is written in TypeScript and uses Docker, and to avoid round-tripping through .js files, we're running it with <a href="https://github.com/TypeStrong/ts-node" rel="noreferrer">ts-node</a> to load the .ts files directly.</p>
<p>Unfortunately this seems to make VSCode confused as to where valid lines of code are for setting breakpoints.</p>
<p>This problem manifests with the following setup:</p>
<h1>/package.json</h1>
<pre class="lang-json prettyprint-override"><code>{
"scripts": {
"start": "node --inspect=0.0.0.0 --require ts-node/register src/index.ts"
},
"dependencies": {
"@types/node": "^10.1.2",
"ts-node": "^6.0.3",
"typescript": "^2.8.3"
}
}
</code></pre>
<h1>/tsconfig.json</h1>
<pre class="lang-json prettyprint-override"><code>{
"compilerOptions": {
"target": "ES2017",
"module": "commonjs",
"outDir": "./dist",
"rootDir": "./src",
"esModuleInterop": true
}
}
</code></pre>
<h1>/Dockerfile</h1>
<pre><code>FROM node
RUN mkdir /home/node/app
WORKDIR /home/node/app
COPY package.json /home/node/app
RUN npm install && npm cache clean --force
COPY . /home/node/app
CMD [ "npm", "start" ]
</code></pre>
<h1>/docker-compose.yml</h1>
<pre class="lang-yaml prettyprint-override"><code>version: "3.4"
services:
http:
build: .
ports:
- "8000:8000"
- "9229:9229"
</code></pre>
<h1>/.vscode/launch.json</h1>
<pre class="lang-json prettyprint-override"><code>{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "attach",
"name": "Attach",
"address": "localhost",
"port": 9229,
"protocol": "inspector",
"localRoot": "${workspaceFolder}/src",
"remoteRoot": "/home/node/app/src"
}
]
}
</code></pre>
<h1>/src/index.ts</h1>
<pre><code>import {createServer} from "http";
const server = createServer((msg, res) => {
res.writeHead(200, {'Content-Type': 'text/plain'})
res.end(msg.url)
debugger
})
server.listen(8000)
</code></pre>
<p>(The blank lines are significant for reasons I'll show later, about ten of them does the job.)</p>
<p>You can also fetch the whole thing here: <a href="https://github.com/millimoose/ts-node-breakpoints" rel="noreferrer">https://github.com/millimoose/ts-node-breakpoints</a></p>
<p>I run this with <code>docker-compose --up</code>, then attach to that with the debugger using the above launch configuration. When I try to set breakpoints in <code>/src/index.ts</code> on any of the lines inside the <code>createServer()</code> call, they're reported as invalid; while I can set breakpoints in the blank lines. This is presumably because TypeScript compilation strips the blank lines, and for some reason, VSCode will only recognize line numbers from the generated JS as valid:</p>
<p><a href="https://i.stack.imgur.com/g4YWo.png" rel="noreferrer"><img src="https://i.stack.imgur.com/g4YWo.png" alt="line number mismatch between TS and JS"></a></p>
<p>This is a contrived example for ease of reproduction, but in general there'll be a mismatch between where I think I'm setting breakpoints, and where they're actually set.</p>
<p>However, when I break on the <code>debugger</code> statement, VSCode fetches the TypeScript file (the tab says something along the lines of "read-only inlined from sourcemap" when newly opened) from the server, and I can then set breakpoints correctly in it:</p>
<p><a href="https://i.stack.imgur.com/rRDu9.png" rel="noreferrer"><img src="https://i.stack.imgur.com/rRDu9.png" alt="breakpoints in local vs. remote file"></a></p>
<p>This is an unsatisfying situation for reasons I shouldn't have to explain: juggling a local file I can edit and a remote file where breakpoints work is a hassle, and adding <code>debugger</code> statements would involve reloading the app everytime I need a new breakpoint.</p>
<p>I've searched around for the issue, but the keywords give me at least ten lengthy GitHub issues ranging as far as years back. Since I'm not intimately familiar with the internals of ts-node, transpilation, and sourcemaps, I'm having a hard time reasoning through what's going on here, much less how to fix it. From what I understand, what happens is that ts-node compiles TS to JS and generates sourcemaps in temporary files inside the Docker container where VSCode can't access them. (This is why I've no idea how to set e.g. <code>outFiles</code>.) There were also some allusions to my scenario being already supported if set up correctly in closed issues, but no clue as to how to do it.</p>
<p>Is there a way to get this working so that I can actually set a breakpoint in my local sources when remote-debugging, and have them hit in said files, without having to revert to precompiling TS to JS and sourcemaps so I have the latter available locally?</p>

Regex to match numeric and special chatacters : I need regex which matches as per below values:
1. abc123 - Do not match
2. 123 - Match
3. a123bc - Do not match
4. a#b%c - Match
5. 13&ab12% - Match
6. আফ্রিকার - Do not match
In short, it matches with only numeric string and any string with special character(#,&,%). Also it do not match with any other language string.
I tried this regex but it didn't work for me.
