How to change Android talkback instructions for double tap and long press : <p>I have a view that has a long press action handler. I use the content description to set the message Talkback speaks when the view gets focus.</p>
<p>Currently it says my content description right after getting a focus, and after a short pause says:</p>
<blockquote>
<p>Double tap to activate, double tap and hold for long press</p>
</blockquote>
<p>I want to change this message into something like</p>
<blockquote>
<p>Double tap to <strong>"action 1"</strong>, double tap and hold for <strong>"action 2"</strong></p>
</blockquote>
<p>Is there a way to do so?</p>
<p>I looked into <code>onPopulateAccessibilityEvent()</code>, it gets <code>TYPE_VIEW_ACCESSIBILITY_FOCUSED</code> event, but I wasn't able to change the desired message. </p>
<p>Am I missing something simple?</p>

Ignore [JsonIgnore] Attribute on Serialization / Deserialization : <p>Is there a way I can ignore Json.NET's <code>[JsonIgnore]</code> attribute on a class that I don't have permission to modify/extend?</p>
<pre><code>public sealed class CannotModify
{
public int Keep { get; set; }
// I want to ignore this attribute (and acknowledge the property)
[JsonIgnore]
public int Ignore { get; set; }
}
</code></pre>
<p>I need all properties in this class to be serialized/deserialized. I've tried subclassing Json.NET's <code>DefaultContractResolver</code> class and overriding what looks to be the relevant method:</p>
<pre><code>public class JsonIgnoreAttributeIgnorerContractResolver : DefaultContractResolver
{
protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)
{
JsonProperty property = base.CreateProperty(member, memberSerialization);
// Serialize all the properties
property.ShouldSerialize = _ => true;
return property;
}
}
</code></pre>
<p>but the attribute on the original class seems to always win:</p>
<pre><code>public static void Serialize()
{
string serialized = JsonConvert.SerializeObject(
new CannotModify { Keep = 1, Ignore = 2 },
new JsonSerializerSettings { ContractResolver = new JsonIgnoreAttributeIgnorerContractResolver() });
// Actual: {"Keep":1}
// Desired: {"Keep":1,"Ignore":2}
}
</code></pre>
<p>I dug deeper, and found an interface called <code>IAttributeProvider</code> that can be set (it had a value of "Ignore" for the <code>Ignore</code> property, so that was a clue this might be something that needs changing):</p>
<pre><code>...
property.ShouldSerialize = _ => true;
property.AttributeProvider = new IgnoreAllAttributesProvider();
...
public class IgnoreAllAttributesProvider : IAttributeProvider
{
public IList<Attribute> GetAttributes(bool inherit)
{
throw new NotImplementedException();
}
public IList<Attribute> GetAttributes(Type attributeType, bool inherit)
{
throw new NotImplementedException();
}
}
</code></pre>
<p>But the code isn't ever hit.</p>

Why am I getting a segmentation fault in c? : I am getting segmentation error when trying to do the CS50 Crack cryptography problem. I am a novice in C language. The code compiles Ok but when I run the debugger it seems to get the following error:
Process received SIGSEGV: Segmentation fault
...at guess[0] = *alphabet1;
I have looked at other stack overflow questions and suspect it could have something to do with string guess being a string literal but this has has muddied the waters for me. Can you please explain me why I am getting segmentation error or direct me to a good webpage to research this. The pertinant code is below. Thanks in advance for any help.
string guess= " ";
string hashed_word= " ";

How to debug a g++ segmentation fault using gdb? : <p>I got a segfault when running my program. Then I googled my question and tried to follow steps from <a href="https://www.gnu.org/software/gcc/bugs/segfault.html" rel="nofollow noreferrer">https://www.gnu.org/software/gcc/bugs/segfault.html</a>.</p>
<p>I did not configure GCC with <code>--enable-checking</code> then my first question is - </p>
<p>1) is it necessary to configure it and compile with <code>-v -da -Q</code> ?</p>
<p>But I always do compile with flags such as <code>-g -o0</code>. After running the program in GDB with arguments I get this:</p>
<p><a href="https://i.stack.imgur.com/EMdFw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/EMdFw.png" alt="gdb_screenshot"></a></p>
<p>2) I can not print variables after segfault, is it okay ?</p>
<p>3) How to figure out the line of my source code where segfault happens ?</p>

Begginer in Java - I can't print on the same line (I'm not using println) : This seems to be a common question but I couldn't find the solution to my problem. I started learning Java very recently so I barely know the basic.
My professor gave an assignement where I have to write my name using asterisks. I did that using only one 'System.out.print' and it's very disorganized and confusing. So I tried this:
public class teste2
{ public static void main (String[] args)
{
String BR = "***** ***** \n* * * *\n* * * *\n***** ***** \n* * * *\n* * * *\n****** ";
String U = "* *\n* *\n* *\n* *\n* *\n* *\n*******";
System.out.print (BR + U);
}
It works but they are in different lines, and I need it to be in just 1 line. What am I doing wrong? | 0debug |

Letters to Numbers in an array : <p>Ok so basically I am working on a final grade calculator for believe it or not, finals. I was asked to use a picker view to select a letter (grade). I am trying to figure out how that when someone selects a letter grade it will use a number like 90 or 80 or so on so I can fit it into my math equation.</p>

C# Recursion to get parent value and children value and all its children's children value : Need help with the following question. I was tested on this and failed and really want to know the answer so that I can study it....
Assume an list (C#) of objects in pyramid structure with the following properties:
• id
• name
• value
• parentid
Example (C#):
var b = new block();<br>
b.id = 100;<br>
b.name = "block 100"<br>
b.value = 102.50;<br>
b.parentid = 99;
Write a recursive function that accepts an ID as the only parameter and will loop through an array or list of an undetermined size and number of levels. The recursive function will calculate

How do I know which stage of jenkins pipeline has failed : <p>In my Jenkins pipelines I generally use <code>post</code> declarative function to send me an email incase the pipeline has failed. </p>
<p>A simple syntax of the <code>post</code> function is as under:</p>
<pre><code>post {
failure {
mail to: 'team@example.com',
subject: "Failed Pipeline: ${currentBuild.fullDisplayName}",
body: "Something is wrong with ${env.BUILD_URL}"
}
}
</code></pre>
<p>In the above email, I also want to mention which stage (lets say the pipeline has 5 to 6 stages) of the pipeline has failed. How can I do that? Any help is much appreciated.</p>
<p>An extension to the above requirement will be to provide the user with the actual error log (of the stage that has failed) also as a part of the failure notification email.</p>
<p>Idea is, when a user receives a failure notification from jenkins, he should know which stage of the pipeline has failed along with the error log.</p>
<p>Thanks in advance.</p>

<p>But when I replace "dev" with "type", which actually always occurs and gives a count of at least 1, then the command is successful and no error is thrown.</p>
<p>I also tried with <code>command:</code> instead of <code>shell:</code> - it doesn't give an error, but then the command is also not executed.</p>

SignalR Core 2.2 CORS AllowAnyOrigin() breaking change : <p>To connect via SignalR to an ASP.NET Core 2.1 server from any origin, we had to configure the pipeline as follows:</p>
<pre><code>app.UseCors (
builder => builder
.AllowAnyHeader ()
.AllowAnyMethod ()
.AllowAnyOrigin ()
.AllowCredentials ()
)
</code></pre>
<p>According to <a href="https://docs.microsoft.com/pt-br/aspnet/core/migration/21-to-22?view=aspnetcore-2.2&tabs=visual-studio#update-cors-policy" rel="noreferrer">this</a> document, ASP.NET Core 2.2 no longer allows the combination of AllowAnyOrigin and AllowCredentials, so what would be the solution? Whereas the SignalR Core always sends withCredentials:true in the XMLHtppRequest.</p>
<p>What I need is that from any origin and without credentials, our users can connect to the SignalR Hub.</p>

Struct method is setting field but they are not being "saved"? : <p>I know the title is confusing, and it is for me as well, as it says I have packets that decode binary data from byte buffers, each data value is set to a specific field of a struct. First I make a new struct of that type and call the "Decode" method: </p>
<pre><code>text := packets.NewTextPacket()
text.Buffer = bytes
text.DecodeHeader()
text.Decode()
</code></pre>
<p>The problem is that I specifically call the method called "Decode", here you can see what it does:</p>
<pre><code>func (pk TextPacket) Decode() {
pk.TextType = pk.GetByte()
pk.Translation = pk.GetBool()
switch pk.TextType {
case Raw, Tip, System:
pk.Message = pk.GetString()
break
case Chat, Whisper, Announcement:
pk.Source = pk.GetString()
pk.SourceThirdParty = pk.GetString()
pk.SourcePlatform = pk.GetVarInt()
pk.Message = pk.GetString()
break
case Translation, Popup, JukeboxPopup:
pk.Message = pk.GetString()
c := pk.GetUnsignedVarInt()
for i := uint32(0); i < c; i++ {
pk.Params = append(pk.Params, pk.GetString())
}
break
}
pk.Xuid = pk.GetString()
pk.PlatformChatId = pk.GetString()
}
</code></pre>
<p>When I print <code>pk.Message</code> inside <code>func (pk TextPacket) Decode()</code> it shows the correct string, but printing it after <code>text.Decode()</code> as <code>text.Message</code>, it shows the default value that is set when the struct is first made, which is an empty string, same goes for all the other fields such as <code>text.TextType</code>, etc.</p>

Is Python a suitable tool for automating data scraping? : <p>I am working on a project which involves working with a large amount of data. Essentially, there exists a large repository on some website of excel files that can be downloaded. The site has several different lists of filters and I have several different parameters I am filtering and then collecting data from. Overall, this process requires me to download upwards of 1,000+ excel files and copy and paste them together.</p>
<p>Does Python have the functionality to automate this process? Essentially what I am doing is setting Filter 1 = A, Filter 2 = B, Filter 3 = C, download file, and then repeat with different parameters and copy and paste files together. If Python is suitable for this, can anyone point me in the direction of a good tutorial or starting point? If not, what language would be more suitable for this for someone with little background?</p>
<p>Thanks!</p>

packaging javascript based plug and play application : I am trying to build a plug and play web based application that I should be able to integrate with multiple other web applications (which are developed using AngalurJS\ ExtJS\ ReactJS etc). On click of a button, I should be able to launch a [sliding menu][1]. On this menu, I want to add Twitter like functionality. On the first half of the menu we will have a textbox (with features like autocomplete & hash tags). The second half with show a gird which will show already posted messages. The panel will be responsible to get and post data to server.
The challenge is, I want to add this functionality to multiple other web applications with minimum configuration\changes. The consuming web applications should be able use this plugin with ease. Certain challenges I see is bootstrap does not play well with ExtJs framework & I may face similar issues with other JavaScript frameworks.
**Questions:**
1. `How can I package this application?` It has a panel with third party plugins (for autocomplete & other features), CSS & JavaScript. I can use web pack or Browserify but I want to keep the solution clean & don't want to add unnecessary dependency.
2. The consumers should be able to consume the bundle\package with ease & just by adding some references (like my bundle, css file, jquery, bootstrap).
I think, I can get the desired result with a simple ReactJs app, which I can bundle using web pack. But this will introduce other dependency. I want to keep the web application lite and simple.

What is the quantifiable benefit of 64 bit for Visual Studio Code over 32 bit : <p>I'm not a hardware guy, but I know that Visual Studio in a 64 bit version issue request was declined by Microsoft stating that a 64 bit version would not have good performance.</p>
<p>Two noticeable differences between the two that I feel are obvious is the code base. One began it's life in 1997, one would think that means more baggage on the Visual Studio side, less opportunities to have very modern application architecture and code and that may make it harder and possibly stuff may be built to perform on 32 bit and for some reason is not suitable for 64 bit? I don't know.</p>
<p>Visual Studio Code on the other hand is an modern Electron app which means it pretty much just compiled HTML. CSS and JavaScript. I'm betting making a version of Visual Studio Code has little in the way of obstructions and although performance may not be something truly noticeable, why not?</p>
<p><strong>P.S.</strong></p>
<p><em>I still would like to understand what areas may be improved in performance and if that improvement is negligible to the a developer. Any additional info or fun facts you may know would be great I would like to have as much info as possible and I will update the question with any hard facts I uncover that are not mentioned.</em></p>

Is this a good approach to random byte array genaration in C? : I know this kind of question has been already discussed here: http://stackoverflow.com/questions/822323/how-to-generate-a-random-number-in-c
But I wanted to share the way I implemented it just to know what people may think about it.
#include <stdlib.h>
#include <string.h>
#include <sys/time.h>
#include <time.h>
long int getNanoSecs(){
struct timespec unixtimespec;
clock_gettime(CLOCK_REALTIME_COARSE, &unixtimespec);
return unixtimespec.tv_nsec;
}
.
.
.
unsigned char personal_final_token[PERSONAL_FINAL_TOKEN_SIZE_SIZE];
unsigned char pwd_ptr_ctr;
srandom(getNanoSecs()*(getNanoSecs()&0xFF));
for(pwd_ptr_ctr=0;pwd_ptr_ctr<PERSONAL_FINAL_TOKEN_SIZE_SIZE;pwd_ptr_ctr++){
memset(personal_final_token+pwd_ptr_ctr,(random()^getNanoSecs())&0xFF,1);
}
just define PERSONAL_FINAL_TOKEN_SIZE_SIZE and you can generate a quite random token of the size you want. | 0debug |

Capturing Video with AVFoundation : <p>I've been looking around on Stack and I have found similar questions to this, but none have worked for me. I am a complete novice to Swift 3.0. Essentially what I'm trying to do is record a video using AVFoundation. So far I have managed to capture a still image, and this is the code I have so far</p>
<pre><code>func beginSession() {

stillImageOutput.outputSettings = [AVVideoCodecKey:AVVideoCodecJPEG]
if captureSession.canAddOutput(stillImageOutput) {
captureSession.addOutput(stillImageOutput)
}
}
catch {
print("error: \(error.localizedDescription)")
}
guard let previewLayer = AVCaptureVideoPreviewLayer(session: captureSession) else {
print("no preview layer")
return
}
self.view.layer.addSublayer(previewLayer)
previewLayer.frame = self.view.layer.frame
captureSession.startRunning()
// Subviews
self.view.addSubview(imgOverlay)
self.view.addSubview(blur)
self.view.addSubview(label)
self.view.addSubview(Flip)
