How do you dynamically control react apollo-client query initiation? : <p>A react component wrapped with an <a href="http://dev.apollodata.com/react/queries.html#basics" rel="noreferrer">apollo-client</a> query will automatically initiate a call to the server for data.</p>
<p>I would like to fire off a request for data only on a specific user input.</p>
<p><a href="http://dev.apollodata.com/react/queries.html#graphql-skip" rel="noreferrer">You can pass the skip option in the query options</a> - but this means the refetch() function is not provided as a prop to the component; and it appears that the value of skip is not assessed dynamically on prop update.</p>
<p>My use is case is a map component. I only want data for markers to be loaded when the user presses a button, but not on initial component mount or location change.</p>
<p>A code sample below:</p>
<pre><code>// GraphQL wrapping
Explore = graphql(RoutesWithinQuery, {
options: ({ displayedMapRegion }) => ({
variables: {
scope: 'WITHIN',
targetRegion: mapRegionToGeoRegionInputType(displayedMapRegion)
},
skip: ({ targetResource, searchIsAllowedForMapArea }) => {
const skip = Boolean(!searchIsAllowedForMapArea || targetResource != 'ROUTE');
return skip;
},
}),
props: ({ ownProps, data: { loading, viewer, refetch }}) => ({
routes: viewer && viewer.routes ? viewer.routes : [],
refetch,
loading
})
})(Explore);

Progress Bar for simple backup script : <p>I am not a programmer at all, however I am teaching myself bash scripting and I have a need for a backup script to backup my VMs (I am using KVM/QEMU). I know that you can do snapshots but I need something more permanent a hard copy of the VM if you will and be able to put these on my ZFS Storage system. So I was thinking to write a backup script that runs via cron once a week or so. The file is of course qcow2 or whatever file system is chosen. So far I have a good start on the script.</p>
<p>Some parts of this script has been borrowed from another author</p>
<pre><code>### kvm-backup.0.0.1 ###
#!/bin/bash
# Get the date #
BACKUPTIME=`date +%b-%d-%y` # Affixing the date
# Create the backup file and cp to Destination for backups #
DESTINATION=/mnt/backups/backup-$BACKUPTIME.tar.gz
# Need to define the source folder #
SOURCEFOLDER=/mnt/VMs/
# create backup now #
tar -cpzf $DESTINATION $SOURCEFOLDER
</code></pre>
<p><strong>### Right here I need a progress bar but I am not sure how put it all together I know the code above will have to be fitted in to one of the progress bar scripts. I am just not smart enough to put it all together. ###</strong></p>
<p>Could someone help me out a little bit,
Thanks,
Michael</p>

Jekyll Code snippet copy-to-clipboard button : <h1>The Problem</h1>
<p>I am building a Jekyll site with the <a href="https://github.com/jekyll/minima" rel="noreferrer">minima</a> theme to publish some tutorial online. The tutorial pages contain many code snippets, for example:</p>
<pre><code>```javascript
/* Global scope: this code is executed once */
const redis = require('redis');
const host = <HOSTNAME>;
const port = <PORT>;
const password = <PASSWORD>;
...
```
</code></pre>
<p>I would like to add a "copy to clipboard" button to each code snippet (<a href="https://clipboardjs.com/#example-target" rel="noreferrer">example</a>), but not sure what's the right way to do it in Jekyll.</p>
<h1>What have I tried</h1>
<ul>
<li>Using <a href="https://clipboardjs.com/#example-target" rel="noreferrer">clipboardjs.com</a>. It requires a unique ID for each snippet, and I'm not sure how to implement this in Jekyll/Markdown.</li>
<li>STFW</li>

<p><strong>How can I add a "Copy to Clipboard" button for code snippets in Jekyll?</strong></p>

I have absolutely no idea how to fix it.
This is how it looks before i do something:

This is how it looks after i add some text or whatever to the box

<p>As you can see, the other box is moving, and the more i write, the further down its going.
Would appreciate some explanation here.</p>

NgModule vs Component : <p>So I'm learning angular2 now and reading ngbook2 about the modules.
Modules contain components, but also can import different modules with their public components.</p>
<p>And the question is: What is the scope of the module component (in this meaning scope as parts of an application, not the reach of variables inside). Is module the whole application or just some part like header, containing its components?</p>
<p>What is the typicaly used convention?</p>

What are the problems with mixing .NET Framework and .NET CORE? : <p>I have a load of middle and back end components (repositories, services etc) that were written against the .NET Framework 4 but that are still relevant to a new project that I'm now working on. The front end of this new project will be written in ASP .NET CORE2.2.
What should I do - recreate all components in .NET CORE or keep the back end running against .NET Framework while the front end runs against CORE? What are the considerations in terms of e.g. performance?</p>

Graph programm in C : I want to write a code in which i want to know how much time is needed to move from one point to another .
Input
1) First line(input) is showing the maximum time required to reach
2) Second line(second and third input) shows the intial position.
3)Third line(fourth and fifth input) shows the final position.
4)fourth line shows the time taken to travel one step in left , right , up and down .

@Input() value is always undefined : <p>I have created a <code>user photo component</code> which takes an <code>@Input()</code> value, this value is the userId.

ngOnInit() {

<p>As you can see I have declared the userId as <code>@Input()</code>, now on my <code>edit-profile component</code> I have the following:</p>
<pre><code><user-photos [userId]="TestingInput"></user-photos>

<p>Now the User Photo component gets rendered as I see the <code>h1</code> tag appearing, however the userId is always undefined ?</p>

Updating a string with string.replace in JS : <p>I have the following question:
I have an array ['cd', 'ef', 'kl'] and a string 'ab(AA)ef(LL)ij(EX)'. I'd like to replace the text between parentheses (AA)s with 'cd', 'ef' and 'ij' respectively to make it 'ab(cd)ef(gh)ij(kl)'. I've written a code to find text between brackets</p>
<pre><code>var s = 'ab(cd)ef(gh)ij(kl)';
var regExp = /\((.+?)\)/g;
var found = [], r;
while(r = regExp.exec(s)) {
found.push(r[1]);
}
</code></pre>
<p>but what should I do next? String.replace(re, found[x]) replaces all brackets with just the first one, as it should, and if I remove /g flag, it finds only the first occurrence (again, as it should). A bit stuck here, could you give me a hint please?</p>

I want to know can I face any issue with battery temperature and how can I keep a trace on the battery temperature. If somebody knows how to solve this problem if I use Arduino boards please inform. I think same solution can work for Feather M0.</p>

When is necessary to add class for semantics? : I want to write semantic beautiful no-nonsense HTML. When is the right time to include class and when it's not? Should I add class on every element of my HTML?
To write semantic markup, we must use HTML tags correctly so that our markup is both human-readable and machine-readable. When we write semantic markup we can no longer select HTML elements based on visual presentation. Instead, we select HTML elements based on their semantic meaning, and then use CSS to define the visual presentation of our content. When writing semantic markup, the presentation of web page elements is kept completely separate and distinct from the markup of the content itself.
<body>
<ul class="post">
<li class="title"> <h3>Title of Post</h3> </li>
<li class="content"><p> Lorem Ipsum bla bla..</p></li>

</li>
</ul>
</body>

Which of these is more semantic? Should we use class on everything or only when necessary? | 0debug |

Can't call setState (or forceUpdate) on an unmounted component : <p>I'm trying to fetch the data from the server after component has been updated but I couldn't manage to do that.

When I should set the state?</p>
<pre><code>async componentDidUpdate(prevProps, prevState) {

Android Google Sign In: check if User is signed in : <p>I am looking for a way to check if my user already signed in with Google Sign In.</p>
<p>I support several logging APIs (Facebook, Google, custom), so I would like to build a static helper method like:
<code>User.isUserLoggedIn()</code></p>
<p>With Facebook I use: </p>
<pre><code>if AccessToken.getCurrentAccessToken() != null {
return true
}
</code></pre>
<p>to check if the user is logged via Facebook.</p>
<p>On iOS I use the following to check if the user is logged via Google Sign In:</p>
<pre><code>GIDSignIn.sharedInstance().hasAuthInKeychain()
</code></pre>
<p><strong>My question:
Is there an equivalent on Android to the iOS method :</strong> </p>
<p><code>GIDSignIn.sharedInstance().hasAuthInKeychain()</code> ?</p>
<p>I am looking for a method that doesn’t involve a callback. </p>
<p>Thanks!

NodeJS Express encodes the URL - how to decode : <p>I'm using NodeJS with Express, and when I use foreign characters in the URL, they automatically get encoded.</p>
<p><strong>How do I decode it back to the original string?</strong></p>
<p>Before calling NodeJS, I escape characters.</p>
<p>So the string: <code>אובמה</code></p>
<p>Becomes <code>%u05D0%u05D5%u05D1%u05DE%u05D4</code></p>
<p>The entire URL now looks like: <code>http://localhost:32323/?query=%u05D0%u05D5%u05D1%u05DE%u05D4</code></p>
<p>Now in my NodeJS, I get the escaped string <code>%u05D0%u05D5%u05D1%u05DE%u05D4</code>.</p>
<p>This is the relevant code:</p>
<pre><code>var url_parts = url.parse(req.url, true);
var params = url_parts.query;

How to mock environment files import in unit tests : <p>In our angular app, we use environment files to load some config. </p>
<p>environment.ts</p>
<pre><code>export const environment = {
production: false,
defaultLocale: 'en_US',
};
</code></pre>
<p>We then use it in one of our service:</p>
<pre><code>import { environment } from '../../environments/environment';
import { TranslateService } from './translate.service';
@Injectable()
export class LocaleService {
constructor(private translateService: TranslateService){}
useDefaultLocaleAsLang(): void {
const defaultLocale = environment.defaultLocale;
this.translateService.setUsedLang(defaultLocale);
}
}
</code></pre>
<p>So I use the values in environment file in a service method.</p>
<p>In our test file, we can of course Spy on the translateService:</p>
<p><code>translateService = jasmine.createSpyObj('translateService', ['setUsedLang']);</code></p>
<p>But I don't know how to mock the environment values in my testing file (in a <code>beforeEach</code> for example). Or even transform it, for testing purpose, to a <code>Subject</code> so I can change it and test different behaviors.</p>
<p>More generally speaking, how can you mock such imports values in tests to be sure not to use real values? </p>

How to restart a game?(tkinter) : I'm making a game with tkinter where the player must dodge acid rain.
I'm almost done with it, I'm just needing a way of restarting the whole game after the Up key is pressed. I already made a function that's being called after rain hit the player. This function checks with an event if the up key is pressed and triggers than the restart function in which the code for restarting the game comes. All inside the Game class.
Here's the code:

How to Systematically use each item in a Vector : <p>I am currently creating a program that initializes a int Vector at the beginning of the program. As the program progresses, Prime numbers will be added to the Vector. Then, the program will check if the result of if the result of a given number % the first number in the Vector == 0. If not, the program will then check it against the second number. Is there a way to do this on C++ 11 and if so, how? Thank you for any time!</p>

passing multiple arguments to promise resolution within setTimeout : <p>I was trying to follow along with the MDN <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/all" rel="noreferrer">promise.all</a> example but it seems I cannot pass more arguments to the <a href="https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/setTimeout" rel="noreferrer">setTimeout callback</a>. </p>
<pre><code>var p1 = new Promise((resolve, reject) => {
setTimeout(resolve, 200, 1,2,3);
});
var p2 = new Promise((resolve, reject) => {
setTimeout(resolve, 500, "two");
});
Promise.all([p1, p2]).then(value => {
console.log(value);
}, reason => {
console.log(reason)
});
</code></pre>
<p>This prints <code>[1, "two"]</code>, where I would expect <code>[1, 2, 3, "two"]</code>. Doing this with <code>setTimeout</code> without promise fulfillment works as expected</p>
<pre><code>setTimeout(cb, 100, 1, 2, 3);
function cb(a, b, c){
console.log(a, b, c);
}
//=>1 2 3

<p>Why doesn't this work with the promise? How can it be made to work with the promise?</p>

NotificationManager getActiveNotifications() for older devices : <p>I want to be able to get active notifications from my Android app on demand. (actually I just need to know if there are any)
I've been searching for this behavior and it seems, like I have only two options: <code>NotificationManager.getActiveNotifications()</code> which is exactly what I need, but is only available from SDK 23 or using a <code>NotificationService</code> but I really dislike this solution as I have to provide the permission to my app to read all notifications which is definitely an overkill. </p>
<p>Does anybody know about any solution which would behave like <code>NotificationManager.getActiveNotifications()</code> and not require SDK >= 23?</p>

Perl: using unpack to split a string into fixed length - then reading the next line : I have an JSON Body of an http post that has to be split into 80 character double quoted strings - but - whenever I use unpack to read the first 80 characters, the string pointer in the source string (which is not CR/LF delimited at the end of each line yet) never changes - e.g. the loop below keeps reading the same string over and over:
@row =unpack 'A80', $body;
foreach $line (@row)
{
@row =unpack 'A80', $body;
print '"'.$line.'"' ;

Repository pattern - Do I "need" a service layer in REST API? : <p><em>Im making this question to get your opinions on the matter, and to see if I'm being dumb or pedantic.</em></p>
<hr>
<h1>Question (tl;dr;)</h1>
<p>Do I "need" the service layer (for good practice) when the repository layer already can do most of the things (like FindUserByID) with queries in a faster way, when the service has to do all these things manually in a much more inefficient and super manual way?</p>
<h1>Description (for those who want to read about my motives)</h1>
<p>So, I've been dealing with Clean Architecture, which is great, but not for REST architecture. Since, Clean Architecture is literally made with a Controllers layer, and RPC is the one that handles controllers, not REST. REST handles resources. <strong>So, I removed the "controller" layer, and I'm also thinking if I really need a "service" layer as well.</strong></p>
<p>So REST needs <strong>"services"</strong> and/or <strong>"repositories"</strong>. The strange thing, is that I think these two overlap. I know that <strong>services</strong> are supposed to <strong>handle "business rules"</strong>. But here's the thing:</p>
<h2>Repositories can do the same job with services, but repositories can do the <strong>same job in a much more efficient way</strong>.</h2>
<p>Since Repositories are allowed to have direct communication with the database, they can use database queries (sql, or nosql ones). Which are much more <strong>efficient to write</strong>, much more <strong>efficient to read</strong>, much more <strong>efficient on performance</strong>.</p>
<h3>Service way:</h3>
<p>Say, you need to find a user by his ID, and then pick a specific friend from his friendlist by his name.</p>
<ul>
<li>You get all the users from <strong>repository</strong></li>
<li>You make a <strong>loop</strong> for all the users</li>
<li>You make a <strong>condition</strong> where you check which user has the ID you want</li>
<li>You make a <strong>loop</strong> for all his friends in the friendlist</li>
<li>You make a <strong>condition</strong> to check the friend's name</li>
</ul>
<p><strong>Summary? Like 20-30 lines of code and slower performance?</strong></p>
<h3>Repository way:</h3>
<pre class="lang-golang prettyprint-override"><code>filter := bson.M{
"_id": id,
"friendlist.name": friendsName,
}
projection := bson.M{
"friendlist": 1
}
friend, err := mongoDb.find(filter, projection)
</code></pre>
<p><strong>Summary? Like 3-4 lines of code, and 99% database performance.</strong></p>
<p>So, is there any real need for the "Service layer" part? Is there any real architectural benefit on splitting it to a service layer and a repository layer, when repository can already do all the jobs much more efficiently by itself?</p>

import { * } from "@angular" instead of "angular2" : <p>I am little confused here in angular2. Many example show like</p>

<p>But actually in <code>node_module</code> there is <code>angular2</code>directory exists. So logically it should be</p>

Is it necessary to encrypt chat messages before storing it into firebase? : <p>As far as I know, Firebase sends data over an HTTPS connection, so that the data is already being encrypted. Although Firebase provides security rules to protect my data structure, I can still be able to see the string messages in the database.</p>
<p>I'm just curious whether it is a good idea to encrypt messages before pushing the data to Firebase or not.
Should I just move on from this topic to something else?</p>
<p>Thank you.</p>

Call function based on template argument type : <p>There are two "C" functions: </p>
<pre><code>void fooA(const char*);
void fooW(const wchar_t*);
</code></pre>
<p>Then there is a wrapper template function:</p>
<pre><code>template<typename _TChar>
void foo(const _TChar* str)
{
// call fooA or fooB based on actual type of _TChar
// std::conditional .. ?
// fooA(str);
// fooW(str);
}
</code></pre>
<p>If the caller calls <code>foo("Abc")</code>, this template function should make a compile-time call to <code>fooA</code>. Similiarly, <code>foo(L"Abc")</code> should make the final call to <code>fooW</code>. </p>
<p>How do I do that? I thought of using <code>std::conditional</code> but couldn't make it.</p>
<p>I cannot make <code>fooA</code> or <code>fooB</code> overloaded, since these are C functions.</p>

Creating date sequence between two given dates - fails on febuary : Im using the following method to create a date sequence between two given dates;
public List<DateTime> dateSeq(DateTime startDate, DateTime endDate)
{
List<DateTime> allDates = new List<DateTime>();
for (DateTime date = startDate; date <= endDate; date = date.AddMonths(1))
allDates.Add(date);
return allDates;
}
Creating a date sequence while incrementing 1 month, when the given date for example are:
startDate: 2017-01-01
endDate: 2017-05-01
the sequence i get is fine:
2017-01-01
2017-02-01
2017-03-01
2017-04-01
2017-05-01
But when the given dates are:
startDate: 2017-01-31
endDate: 2017-05-31
The sequence i get fail when passing febuary setting the rest of the months sequence on the 28th day:
2017-01-31
2017-02-28
2017-03-28
2017-04-28
2017-05-28
Can someone please explain why is that?

0.3492275, 0.0065675, 0.0593175, 0.0017225, 0.0007025])
x.argmin()
# 9
</code></pre>
<p>What's the R way of doing that</p>

Separate Nubers From A String : I Am Currently Working On An Artificial Intelligence ROBOT Named "PokeBOT".
I Have Made It Purely In Java.
I Have Successfully Made It's First Version (Check It Here -> https://www.youtube.com/watch?v=Fz9P3JIkHbM&feature=youtu.be).
But It's Not Too Good.
Now I Want To Upgrade It.
That's Where I Need Your Help.
I Want To Take An Input As String And Separate The Numbers From It..
Can I Do It ??
Here's What I Exactly Want To Do...
INPUT: Add 25 And 25
OUTPUT : 50
INPUT: Subtract 50 From 100
OUTPUT: 50
Here I Can Use Input = Input.toUpperCase();
And The Input.contains("ADD"); Function To Detect Addition, Subtraction, etc.
If This Is Possible, Then Please Help.
Thanks In Advance!!

React js destructuring assignment : I have the following function.
```
returnStateElement = (...elements) => {
const copy = Object.assign({}, this.state);
return elements.reduce((obj, key) => ({ ...obj, [key]: copy[key] }), {});
};
```
Work:
```
f = () => {
const dataSender = this.returnStateElement('email', 'password');
let { email, password } = dataSender;
console.log(dataSender,email,password);
}
```
No work:
```
f2 = () => {
const { email, password } = dataSender = this.returnStateElement('email', 'password');
console.log(dataSender,email,password);
}
```
There is a way to make a more compact type of assignment like f2 (), but that works. | 0debug |

Texas Holdem odds evaluating package for Python : <p>I write my master thesis on "Estimation of poker skills value in late tournament phase". I encountered a problem because i can not find python package which would evaluate hand odds versus each other.</p>
<p>What is satisfying for my is simply function:
odds(AsAc, KsKc) which would return [% that AsAc wins, % that KsKc wins]</p>
<p>I tried package PokerSleuth but it does not work on my pc.
(<a href="http://www.barsoom.org/scriptable-equity-calculator" rel="nofollow">http://www.barsoom.org/scriptable-equity-calculator</a> - maybe it works for You)</p>
<p>Do You happen to know any python holdem package with function of odds estimation or do You posses a table with all hands vs all hands odds value?</p>
<p>Thanks in advance!</p>

Why do Azure Functions take an excessive time to "wake up"? : <p>We have a simple Azure Function that makes a DocumentDB query. It seems like the first time we call it there is a long wait to finish, and then successive calls are very fast.</p>
<p>For example, I just opened our app and the first Function call took 10760ms, definitely noticeable by any end user. After this, all Function calls take approximately 100ms to process and are nearly imperceptible.</p>
<p>It seems as though there is some "wake up" cycle in Azure Functions. Is there some way to minimize this, or better yet is this documented somewhere so we can understand what's really going on here?</p>
