C# button up/down/left/right not detected : <p>A week ago I used this for detecting the <code>up/down/left/right keys</code> in my
wpf application:</p>
<pre><code>private void Invaders_KeyDown(object sender, KeyEventArgs e)
{
MessageBox.Show(e.KeyCode.ToString());
switch (e.KeyCode.ToString())
{
case "Up":
MessageBox.Show("Up");
break;
case "Down":
MessageBox.Show("Down");
break;
case "Left":
MessageBox.Show("Left");
break;
case "Right":
MessageBox.Show("Right");
break;
}
}
</code></pre>
<p>But today I started a new application and this does not work anymore? It detects everything except <code>up/down/left/right</code>. What could be going on here?</p>

How to make reactive variables between COMPONENTS? Angular 2/4 : Good Stackers, Today I propose a doubt that I can not find or identify.
Lately I'm practicing with the **Inputs / Outputs** and this has led me to do this example:
In component A, I have `@Output () outputVariableA = [hi, hi2, hi3]`
In component B, I have `@Input () inputVariableB [];`
In component B, I define a function that modifies the inputVariableB.
How do I make it REACTIVE, between the two VARIABLES the modification
And that the modified data of the **inputVariableB** is reflected in the **outputVariableA**
> If it has not been understood, ask me.
Thank you very much for helping!

<p>This is my code for an homework assignment I have to modify a program in the book (Which I'd much rather make my own program), but the instructions say: Modify the program to validate the two letter state codes for the northeast states. It then lists the different states and the corresponding codes, all of which are in my code. Then it says: In the State property's set accessor, use the logical OR (||) operator to create a compound condition in an if...else statement that compares the method's argument with each two-letter code.</p>
<p>I apologize for the huge block of code but I'm not sure what's causing the problem (I'm kind of new to c#), but the error I'm getting: is operator '||' cannot be applied to operands of type 'string' and 'string'. Any help would be appreciated, as this makes little sense to me, as being new to language. Thanks!</p>

Generic type 'Result' specialized with too few type parameters (got 1, but expected 2) : <p>I just wanted to include Result in my project and am running across a few issues. It seems to me as if Alamofire (which is already a dependency) defines its own Result type throwing problems when trying to write functions that return results.</p>
<p>For example Xcode (10.2 beta 4) tells me that I can't write Result-> Response = (_ result: Result) -> Void because Generic type 'Result' specialized with too few type parameters (got 1, but expected 2).</p>
<p>Both are linked as frameworks installed via Cocoapods in a "Swift 5.0 beta" project.</p>
<p>I'm guessing issues like this shouldn't actually be occurring, but I'm doing something wrong here. Any pointers would be great, thank you!</p>

Connecting a Laser Distance Measurer (Bosch Disto GLM 50 C) with Smartphone (Android Studio) : <p>I got stuck at a special problem (I think).

Why use async when I have to use await? : <p>I've been stuck on this question for a while and haven't really found any useful clarification as to why this is.</p>
<p>If I have an <code>async</code> method like:</p>
<pre><code>public async Task<bool> MyMethod()
{
// Some logic
return true;
}
public async void MyMethod2()
{
var status = MyMethod(); // Visual studio green lines this and recommends using await
}
</code></pre>
<p>If I use <code>await</code> here, what's the point of the asynchronous method? Doesn't it make the <code>async</code> useless that VS is telling me to call <code>await</code>? Does that not defeat the purpose of offloading a task to a thread without waiting for it to finish?</p>

Can someone help me through? Java/Rectangles : i am currently working with a project involving rectangles and i want to create a public method which takes as a definition another rectangle and returns the smallest possible distance between them.(it can be calculated through the smaller possible distances of each projection on each axis respectively).
I also need another method that returns the biggest possible distance between 2 rectangles. I am quite confused by the complexity needed and not sure how to construct it and would like some help.
http://imgur.com/IcHTGII --> this is an example .
Here are the basic constructors used to develop it.
class Rectangle
{
private int dimensionality;
private double[] lowerBound;
private double[] upperBound;
public Rectangle(int dimensionality){
this.dimensionality = dimensionality;
lowerBound = new double[dimensionality];
upperBound = new double[dimensionality];

Trying to understand the differences between CanActivate and CanActivateChild : <p>So, I'm trying to protect the access to several routes by using guards. I'm using the following routes to do so :</p>
<pre><code>const adminRoutes : Routes = [
{
path: 'admin',
component: AdminComponent,
canActivate: [ AuthGuardService ],
children : [
{
path: '',
canActivateChild: [ AuthGuardService ],
children: [
{ path: 'edit', component: DashboardComponent},
{ path: '', component: DashboardComponent}
]
}
]
}
];
</code></pre>
<p>Here's a look at what <code>AuthGuardService</code> looks like</p>
<pre><code>import { Injectable } from '@angular/core';
import {CanActivate, Router, ActivatedRouteSnapshot, RouterStateSnapshot} from "@angular/router";
@Injectable()
export class AuthGuardService implements CanActivate{
constructor(private router: Router) { }
canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot){
console.log("Guarding...");
return this.sessionValid();
}
canActivateChild(route: ActivatedRouteSnapshot, state: RouterStateSnapshot){
console.log("Guarding children...");
return this.canActivate(route, state);
}
sessionValid() : boolean {
//tests
}
}
</code></pre>
<p>When I try to access to '/admin' and '/admin/edit' with <code>canActivate</code> only (<code>canActivateChild</code> is commented) the console displays</p>
<pre><code>Guarding...
</code></pre>
<p>When I remove <code>canActivate</code>and bring <code>canActivateChild</code>back the console displays </p>
<pre><code>Guarding children...
</code></pre>
<p>When I keep both, it goes back to displaying <code>Guarding...</code>.
So, my question is what's the purpose of having <code>canActivateChild</code> when <code>canActivate</code>protects both the root element and the children ?</p>
<p>PS : I get it that <code>canActivateChild</code> runs before the child route is activated. But what are the benefits of that ? Isn't keeping only one of them sufficient ?</p>

Technology stack selection : PHP, Ruby on Rails with World Press : <p>I have to create a web site with the functionality of similar to some e-commerce website, but it will also have a user forum and the users will have ability to write blogs/articles. I will also have a mobile app (hybrid app for iOS and android), so I want my server side Rest APIs to be re-usable from my web front as well as from mobile app perspective (not 100% but at least the platform and technology I want to be same, so it will be easy for me to write back end code for my website and mobile app).</p>
<p>With above in my mind, I would prefer to leverage something like world press , as it will save me a lot of design and tempting time for my website and it also have forum plugins etc. I am the single developer who will be doing everything.</p>
<p>My questions are as below :</p>
<ol>
<li>If I go with World press, my only technology options are PHP/MySQL, is it correct? if yes, then how good the idea is to create REST APIs in PHP? up to what extend World press gives me option to write my custom code and customize my website from coding perspective?</li>
<li>Is Ruby on Rails a better fit for this scenario? can I use RoR with World Press? How are RoR server side REST APIs in terms of performance?</li>
<li>Not leaning towards the Node js solution as my use cases are not really heavily real time features, but more of a CRUD operations, and on top of that I will not be able to leverage any CMS such as World Press in this case.</li>
<li>For forum, is it a good idea to leverage some plugin such as bb press, or vBulletin? any other better option? I think writing of all the forum functionality from scratch won’t be a good idea.</li>
</ol>
<p>Any guidance will be highly appreciated.</p>

Can anyone help me with the errors the given code showing? Help me to compile the code fully : It's a manipulation of two codes.
first i send the latitude and longitude value found from the gps module by sms(arduino,gsm module), then by another code i send it to a php file in the server by using http protocol(arduino+gps/gsm/gprs shield). Now when i am merging two codes,it's showing errors like below:

How to know up and down pattern on CandleStick using plotly python? : I have tried to plot the Candle Sticks for my data using the `plotly` library with Python. Using the typical plotting way, I got the following graph:
Candle = go.Candlestick(x=stock.index,
open=stock.open,
high=stock.high,
low=stock.low,
close=stock.close
)
Output:
[![candles image][1]][1]
Its cool. But what I was expecting to draw the image is something like the following:
[![candles with arrow][2]][2]
See the up green arrow and the down red arrow. I want to know how I can plot such graph using the plotly or any other library. Kindly, suggest me what will be helpful to get such a graph.

How to Prevent 'UI Freeze by using .GetFiles in WPF' : <p>This is a fuction that compare the contents of two folders.</p>
<p>Issue:</p>
<p>When using System.IO.DirectoryInfo.GetFiles() the application is freezing (15
sec), I know that's because it's using the main thread... it's 10 GB.</p>
<p>The reason why I'm not using a thread, sync or whatever is because I need the
"fileInfosToCopy" list in by main thread, so when I'm going to use a thread I
can not access it anymore.</p>
<p>Any ideas? I only need the "fileInfosToCopy" list in my main thread.</p>
<pre><code>string pathA = @"\\server\share\folder";
string pathB = @"C:\folder";
public void Scan()
{
try
{
string Computer = "server";
Ping ping = new Ping();
PingReply reply = ping.Send(Computer);
if (reply.Status == IPStatus.Success)
{
var netwerkfolder = new DirectoryInfo(pathA);
var localfolder = new DirectoryInfo(pathB);
var networkfiles = netwerkfolder.GetFiles("*.*", SearchOption.AllDirectories);
var localfiles = localfolder.GetFiles("*.*", SearchOption.AllDirectories);
var listmissingfiles = networkfiles.Select(s => s.Name).ToList().Except(localfiles.Select(s => s.Name)).ToList();
var fileInfosToCopy = new List<FileInfo>();
foreach (var info in networkfiles)
{
if (listmissingfiles.Contains(info.Name))
{
fileInfosToCopy.Add(info);
}
}
}
else
{
// not connected
}
}
catch (Exception)
{
// x
}
}
}

how to use vue-router params : <p>I'm new to vue now working with its router.
I want to navigate to another page and I use the following code:</p>
<pre><code>this.$router.push({path: '/newLocation', params: { foo: "bar"}});
</code></pre>
<p>Then I expect it to be on the new Component </p>
<pre><code>this.$route.params
</code></pre>
<p>This doesn't work.
I also tried:</p>
<pre><code>this.$router.push({path: '/newLocation'});
this.$router.push({params: { foo: "bar"}});
</code></pre>
<p>I've inspected the source code a bit and noticed this property gets overwritten with new object {}.</p>
<p>I'm wondering is the params use is other than I think?
If not, how to use it?</p>
<p>Thanks in advance</p>

Using c# ClientWebSocket with streams : <p>I am currently looking into using websockets to communicate between a client/agent and a server, and decided to look at C# for this purpose. Although I have worked with Websockets before and C# before, this is the first time I using both together. The first attempt used the following guide:
<a href="http://www.codeproject.com/Articles/618032/Using-WebSocket-in-NET-Part">http://www.codeproject.com/Articles/618032/Using-WebSocket-in-NET-Part</a></p>
<pre><code>public static void Main(string[] args)
{
Task t = Echo();
t.Wait();
}
private static async Task Echo()
{
using (ClientWebSocket ws = new ClientWebSocket())
{
Uri serverUri = new Uri("ws://localhost:49889/");
await ws.ConnectAsync(serverUri, CancellationToken.None);
while (ws.State == WebSocketState.Open)
{
Console.Write("Input message ('exit' to exit): ");
string msg = Console.ReadLine();
if (msg == "exit")
{
break;
}
ArraySegment<byte> bytesToSend = new ArraySegment<byte>(Encoding.UTF8.GetBytes(msg));
await ws.SendAsync(bytesToSend, WebSocketMessageType.Text, true, CancellationToken.None);
ArraySegment<byte> bytesReceived = new ArraySegment<byte>(new byte[1024]);
WebSocketReceiveResult result = await ws.ReceiveAsync(bytesReceived, CancellationToken.None);
Console.WriteLine(Encoding.UTF8.GetString(bytesReceived.Array, 0, result.Count));
}
}
}
</code></pre>
<p>Although this seems to work as expected, I was wondering if there is any way I can use the built in streams/readers in .NET with ClientWebSocket?</p>
<p>Seems odd to me that Microsoft has this rich well established set of stream and reader classes, but then decides to implement ClientWebSocket with only the ability to read blocks of bytes that must be handled manually.</p>
<p>Lets say I wanted to transfer xml, it would be easy for me to just wrap the socket stream in a XmlTextReader, but this is not obvious with ClientWebSocket.</p>

Collapse a doubleColumn NavigationView detail in SwiftUI like with collapsed on UISplitViewController? : <p>So when I make a list in SwiftUI, I get the master-detail split view for "free".</p>

var body: some View {
NavigationView {
List {
ForEach(people, id: \.self) { person in
NavigationLink(destination: Text("Hello!")) {
Text(person)
}
}
}
Text("🤪")
}
}

<p>I get a splitView if an iPad simulator is in landscape, and the first detail screen is the emoji. But if people tap on a name, the detail view is "Hello!"</p>
<p>All that is great.</p>
<p>However, if I run the iPad in portrait, the user is greeted by the emoji, and then there is no indication that there is a list. You have to swipe from left to right to make the list appear from the side.</p>
<p>Does anyone know of a way to get even a navigation bar to appear that would let the user tap to see the list of items on the left? So that it's not a screen with the emoji only?</p>
<p>I would hate to leave a note that says "Swipe in from the left to see the list of files/people/whatever"</p>
<p>I remember UISplitViewController had a collapsed property that could be set. Is there anything like that here?</p>

how to how to send code to node server from js file? : I'm trying to do google authentication in my website in which the user get authenticated on my web page and after authentication it generates a code which contains `access_token` and `refresh_token` and now i want to send it to my Node server.
I know `Xhttp` is a way but i want to avoid that.
So I tried using handle bars but they only work for html right?
so is there is anyway i could use something like `helpers` to send my code to the server?
I tried to get around some posts like [how-can-i-share-code-between-node-js-and-the-browser][1] (which i think is quite old, node must've evolved till then right ?)
and https://stackoverflow.com/questions/45032412/sending-data-from-javascript-html-page-to-express-nodejs-server (i didn't understood this one honestly)
I'm new to Node.js so any guesses or any reference to the docs?

how to create function which returns a dataURL(base64) by taking image URL in node js? : actually there are many answers for this question. But my problem is,
i want to generate pdf dynamically with 5 external(URL) images. Im using PDFmake node module.
it supports only two ways local and base64 format. But i don't want to store images locally.
so my requirement is one function which takes url as parameter and returns base64.
so that i can store in global variable and create pdfs
thanks in advance

How do I replace while loops with a functional programming alternative without tail call optimization? : <p>I am experimenting with a more functional style in my JavaScript; therefore, I have replaced for loops with utility functions such as map and reduce. However, I have not found a functional replacement for while loops since tail call optimization is generally not available for JavaScript. (From what I understand ES6 prevents tail calls from overflowing the stack but does not optimize their performance.)</p>
<p>I explain what I have tried below, but the TLDR is:
If I don't have tail call optimization, what is the functional way to implement while loops?</p>
<p>What I have tried:</p>
<p>Creating a "while" utility function:</p>
<pre><code>function while(func, test, data) {
const newData = func(data);
if(test(newData)) {
return newData;
} else {
return while(func, test, newData);
}
}
</code></pre>
<p>Since tail call optimization isn't available I could rewrite this as:</p>
<pre><code>function while(func, test, data) {
let newData = *copy the data somehow*
while(test(newData)) {
newData = func(newData);
}
return newData;
}
</code></pre>
<p>However at this point it feels like I have made my code more complicated/confusing for anyone else who uses it, since I have to lug around a custom utility function. The only practical advantage that I see is that it forces me to make the loop pure; but it seems like it would be more straightforward to just use a regular while loop and make sure that I keep everything pure.</p>
<p>I also tried to figure out a way to create a generator function that mimics the effects of recursion/looping and then iterate over it using a utility function like find or reduce. However, I haven't figured out an readable way to do that yet.</p>
<p>Finally, replacing for loops with utility functions makes it more apparent what I am trying to accomplish (e.g. do a thing to each element, check if each element passes a test, etc.). However, it seems to me that a while loop already expresses what I am trying to accomplish (e.g. iterate until we find a prime number, iterate until the answer is sufficiently optimized, etc.).</p>
<p>So after all this, my overall question is: If I need a while loop, I am programming in a functional style, and I don't have access to tail call optimization, then what is the best strategy.</p>

pass arguments command line in Perl : I have written the Perl code and trying to pass the commandline arguments and not getting expected out put
here is my code
my ($buildno, $appname, $ver) = @ARGV;
print values \@ARGV;
$Artifact_name="flora-$appname-$ver";
mkdir "$target_dir/$Artifact_name";'
When i run the Perl script 'perl scripts\perl\test.pl "MobileApp", %ver%
after execute the Perl i am getting the following output 'flora-MobileApp-'
And the log message is showing
'Use of uninitialized value $ver in concatenation (.) or string at
Jscripts\perl\test.pl line 31 (#3)'.
%ver% is the environment variable and value is 1.0.1.23
I am expecting the output "flora-MobileApp-1.0.1.23". please can anyone advise on the same.

Git: pull vs. fetch→pull : <p>I've never been able to get a clear answer to this question.</p>
<p>For a long time, and at the advisement of a coworker, I've been doing this:</p>
<pre><code>git fetch origin
git pull origin <mybranch>
</code></pre>
<p>I've been told (and have seen) that <code>git pull</code> does not behave the same way if you do not first do <code>git fetch</code>. You don't get any remote changes.</p>
<p>But all I see online is that <code>git pull</code> is the equivalent of <code>git fetch</code> followed by <code>git merge</code>. If that were true, <code>git pull</code> would include <code>git fetch</code>, and I wouldn't need an explicit <code>git fetch</code> first, right? But that doesn't seem to be the case.</p>
<p>So what I'm looking for is some explicit documentation that describes the observed behavior of <code>git pull</code>. (I know I'll probably also get lots of advice to switch to <code>git fetch</code> → <code>git merge</code>; that's fine too, but I'm really interested in <code>git pull</code>.)</p>

Is it possible to keep Tizen application alive non stop : <p>recently I’ve started developing for Tizen OS. My application is created only for wearable and only for specific device which is Samsung Gear Sport (Tizen 3.0 on board). Main purpose of this application is to gather complete sensor data over a long period of time. I’m interested in heart rate, and movement sensors in general (gyroscope and accelerometer). Then, this data will be send to cloud server and analysed. Currently I’m considering a WEB application because so far I have found no evidence that WEB API is missing something that exists in native API.</p>
<p>But there is one limitation in Tizen OS that so far I am unable to overcome. My application is put to sleep after a while (10 minutes or so). It is crucial that this app should work in the background for a long time (up to 10 hours). To achieve this, I’ve tried following approaches:</p>
<ul>
<li><strong>Normal Tizen app with background-category:</strong> data given by this approach is still too fragmented, for example I got 15 minutes holes where no data was recorded at all. Sometimes there were holes even longer than 30 minutes.</li>
<li><strong>Tizen alarms API:</strong> alarms did the job in case of keeping the app alive, but with every alarm, app was brought to the front and this is not an acceptable solution. There is an option to silently wake up the app (using app control), but it does not have any callback, so all alarms would have to be scheduled upfront.</li>
<li><strong>CPU_AWAKE flag</strong> made the system show “this app is using too much energy” popup, and when not answered within 10 minutes or so, system would kill my app nonetheless.</li>
<li><strong>Web Workers</strong> - this one is only for the sake of argument, web workers are put to sleep along with the application</li>
<li><strong>Data recording:</strong> I was hoping for something similar to Apple Health Kit, but instead I got something that is not working for HRM at all. Somehow it works for <code>PRESSURE</code> sensor. Tizen allows to start recording for <code>HRM</code> but nothing is recorded after - <code>NotFoundError: Failed to read recorded data</code>. Any other sensor gives <code>TypeMismatchError</code>.</li>
<li><strong>Web Service app</strong> - this one requires partner-level certification with Samsung, also it’s affected by the background limitations, <a href="https://developer.tizen.org/ko/development/guides/native-application/application-management/applications/service-application?langredirect=1" rel="noreferrer">as the documentation mentions.</a> </li>
<li><strong>Watch Face</strong> approach with “keep always on” flag set to true in device settings. This solution was the best I’ve tried. Watch face app wakes up every minute to change the time and it also receives sensor data. Unfortunately after more testing it turned out that there were couple holes in the data recorded.</li>
</ul>
<p>About the battery: none of the above was draining the battery to a point where it became unacceptable. So first I’d like to find a solution that will give me all the sensor data I need, as frequently as possible from at least 10 hours, with no holes in it. And after that, if it turns out that this solution is draining too much battery, I will think about how to optimize it.</p>
<p>And now the question: <strong>is it possible to keep my application alive for 10+ hours non stop?</strong></p>

How to split a dataframe based on the index :
I would like to split the below DF_input based on the index. That's from the below DF, How to obtain:
measurement value
0 0 13
1 1 3
2 2 4
0 0 8
1 1 12
2 2 34
3 5 54
DF_output1
measurement value
0 0 13
1 1 3
2 2 4
DF_output2
measurement value
0 0 8
1 1 12
2 2 34
3 5 54
What I did is the following:`
df_input.reset_index(inplace=True)
shifted = df_dataset['index'].shift()
m = shifted.diff(-1).ne(0.000000)
a = m.cumsum()
aa = df_dataset.groupby([df_dataset.uuid,a])
for k, gp in aa:
print(gp)
What Am I doing wrong? Any help please would be very appreciated.
Best Regards, Carlo

Can we consider AWS Glue as a replacement for EMR? : <p>Just a quick question to clarify from Masters, since AWS Glue as an ETL tool, can provide companies with benefits such as, minimal or no server maintenance, cost savings by avoiding over-provisioning or under-provisioning resources, besides running on spark, I am looking for some clarifications, if AWS Glue can replace EMR?</p>
<p>If both can co-exist, how EMR can play a role along with AWS Glue?</p>
<p>Thanks & regards</p>
