Filter prometheus results by metric value, not by label value : <p>Because <a href="https://stackoverflow.com/questions/38783424/prometheus-topk-returns-more-results-than-expected">Prometheus topk returns more results than expected</a>, and because <a href="https://github.com/prometheus/prometheus/issues/586" rel="noreferrer">https://github.com/prometheus/prometheus/issues/586</a> requires client-side processing that has not yet been made available via <a href="https://github.com/grafana/grafana/issues/7664" rel="noreferrer">https://github.com/grafana/grafana/issues/7664</a>, I'm trying to pursue a different near-term work-around to my similar problem.</p>
<p>In my particular case most of the metric values that I want to graph will be zero most of the time. Only when they are above zero are they interesting.</p>
<p>I can find ways to write prometheus queries to filter data points based on the value of a <em>label</em>, but I haven't yet been able to find a way to tell prometheus to return time series data points only if the value of the <em>metric</em> meets a certain condition. In my case, I want to filter for a value greater than zero.</p>
<p>Can I add a condition to a prometheus query that filters data points based on the metric value? If so, where can I find an example of the syntax to do that?</p>

AWS Elastic Beanstalk: Add custom logs to CloudWatch? : <p>How to add custom logs to CloudWatch? Defaults logs are sent but how to add a custom one?</p>
<p>I already added a file like this: (in .ebextensions) </p>
<pre><code>files:
"/opt/elasticbeanstalk/tasks/bundlelogs.d/applogs.conf" :
mode: "000755"
owner: root
group: root
content: |
/var/app/current/logs/*
"/opt/elasticbeanstalk/tasks/taillogs.d/cloud-init.conf" :
mode: "000755"
owner: root
group: root
content: |
/var/app/current/logs/*
</code></pre>
<p>As I did bundlelogs.d and taillogs.d these custom logs are now tailed or retrieved from the console or web, that's nice but they don't persist and are not sent on CloudWatch.</p>
<p>In CloudWatch I have the defaults logs like<br>
<code>/aws/elasticbeanstalk/InstanceName/var/log/eb-activity.log</code><br>
And I want to have another one like this<br>
<code>/aws/elasticbeanstalk/InstanceName/var/app/current/logs/mycustomlog.log</code></p>

Capturing a lambda in another lambda can violate const qualifiers : <p>Consider the following code:</p>
<pre><code>int x = 3;
auto f1 = [x]() mutable
{
return x++;
};
auto f2 = [f1]()
{
return f1();
};
</code></pre>
<p>This will not compile, because <code>f1()</code> is not const, and <code>f2</code> is not declared as mutable. Does this mean that if I have a library function that accepts an arbitrary function argument and captures it in a lambda, I always need to make that lambda mutable, because I don't know what users can pass in? Notably, wrapping <code>f1</code> in <code>std::function</code> seems to resolve this problem (how?).</p>

Users have to upload a csv file based on which the dashboard selects all the numeric variables within the file and provides an option to select any numeric variable to analyze as a dropdown. I want to add a javascript code in the application which will capture the updated measures (e.g. mean) after a user has selected a particular dimension from the dropdown. For example, suppose the default selected dimension in the dropdown window is "sales" and the corresponding mean is 325. If I select another dimension (suppose) "profit" then the mean changes to 37. Now I want to add a javascript/jquery code which will capture the mean value of 37 when I select "profit" (from "sales") from the dropdown. I have tried the <strong>.change</strong> event to check for the change in the dropdown selection and when there is a change, capture the mean value inside the <strong>h3</strong> tag. However, I am getting the previous mean value instead of the updated one i.e. I am getting 325 instead of 37 when I select "profit" (from "sales"). Hope I am clear on this. </p>
<p>Am I using the wrong event? How can I capture anything after a certain action occurs and the values are updated? </p>
<p>Feel free to let me know if you need any more details on my query. Looking forward to the help from the community.</p>

Can a website block user depending on their behaviour or give 404 error to that user? : <ol>
<li>Like if user is giving wrong index continues for like SQL injection</li>
<li>OR Like if user is giving wrong index continues for like DOS attack</li>
<li>Or if i don't want any visitors from certain country
I just wanna know weather it's possible or not, if yes how it works?</li>

<p>Tried different solution from the google search, Non of them worked. I want to avoid using keytool because I will be running my tests on different vm.</p>
<p>Does anyone have any solution for this?</p>

Android Room + AsyncTask : <p>My team have developed a new Android app which makes extensive use of Room.</p>
<p>I am unsure whether we are using AsyncTask correctly.</p>
<p>We have had to wrap all calls to insert/update/delete in AsyncTasks which results in a huge number of AsyncTasks. All the calls into Room are from background services. There is no direct Room access from activities or fragments - they get everything via LiveData.</p>
<p>An example call to insert a row:</p>
<pre><code>AsyncTask.execute(() -> myModelDAO.insertInstance(myModel));
</code></pre>
<p>With this in the DAO:</p>
<pre><code>@Insert
void insertInstance(MyModel model);
</code></pre>

How to cancel Alamofire.upload : <p>I am uploading images on server via <code>Alamofire.upload</code> as multipart data. Unlike <code>Alamofire.request</code> it's not returning <code>Request</code> object, which I usually use to cancel requests. </p>
<p>But it's very reasonable to be able to cancel such a consuming requests like uploading. What are the options for this in Alamofire?</p>

How can I make a c# application outside of visual studio? : <p>I'm very new to programming and I'm teaching myself. I made a calculator for some calculations we do in the lab I work in and wanted to be able to open the app from the computer at work instead of opening it on visual studio from my laptop. Just curious if this is possible, and I've been trying to Google if this is possible but I don't think I'm using the right words in my searches.</p>
<p>If this is possible, it'd be awesome if someone could help me out with an explanation or a link to a video or thread that already explains this. </p>
<p>Thank you for your time!!</p>

Any way to visualize the transform origin point in CSS? : <p>I'm trying to make an object move along an arc, for which I need to set the <code>transform-origin</code> point away from the object itself and then <code>rotate</code> it. So instead of blindly moving the <code>transform-origin</code> point using different lengths and then finally achieving the desired result through trial and error, is there a way to make the point visible to make the process easier?</p>

Difference between using the Stack or the Heap : <p><strong>Are there any problems when using the stack instead of the heap?</strong></p>
<p>Basically I want some 200 positions in memory (or more, 1000, who knows, this is hypothetical anyways), I can allocate it in the stack using an array, or on the heap using <code>malloc()</code>. On the heap I have to remember to always <code>free()</code> the memory...but using the stack, as soon as the function returns, all the memory is nicely cleaned for me.</p>
<p>I am just wondering if there are any issues with holding large amounts of memory on the stack. As far as I know, the stack and the heap are basically the same, just they sit on opposite sides in a RAM frame, and they grow towards the other, like in the image below.</p>

Laravel Passport Print Personal Access Token : <p>I am using Laravel's passport package to provide token based authentication to my rest api. Right now, I am using <a href="https://laravel.com/docs/5.3/passport#personal-access-tokens">personal access token</a> concept to generate the access token.</p>
<p>To generate an access token for a single user, I am using below code to generate a token with name '<strong>android</strong>'.</p>
<pre><code> $user = User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => bcrypt($data['password']),
]);
// Here the access token will be stored in $token variable.
$token = $user->createToken('android')->accessToken;
// Now the $token value would be something like

</code></pre>
<p>Later on I want to display the <strong>personal access token</strong> on my admin dashboard which I am facing difficulty in getting the generated token again. Tried below code, but couldn't able to get the access token.</p>
<pre><code>$user = User::find(1)
dd($user->tokens())
</code></pre>
<p>I also tried using passport vue elements, but it is displaying just the access token name, not the actual token.</p>

Why does a count formula return 0 when the range of cells are linked to another sheet? : <p>I am trying to count a range of cells that have text in and ignore 0 that is in some of these cells. All of these cells have a link to another cell sheet within the same workbook and so are returning 0 if the linked cell has nothing entered.

Flutter - Is it possible to extract data from a Future without using a FutureBuilder? : <p>I'm reading in user-provided input (in this case a zip code) from a <code>TextField</code> that I need to check against a database for validity. However, I need to make an asynchronous database query inside of the submit button's (a <code>RaisedButton</code> in this case) <code>onPressed: () {}</code> lambda function. In most programming languages, this is a fairly straightforward and simple task. The problem I'm running into in Flutter, however, is the fact that <code>Future</code> objects returned from asynchronous database queries can only be consumed by <code>FutureBuilder</code> objects which in turn only return <code>Widget</code> objects. I simply need a <code>String</code> returned that I can then use to either pass to a new route via a <code>MaterialPageRoute</code> object, or display an error to the user without changing routes. Is there any way to do this with Flutter? Returning a Widget is useless to me as I don't want to create a new Widget for display. I am using Flutter 0.3.2 and Dart 2.0.0</p>
<p>As a simplified example of where I need to call the database query:</p>
<pre><code>@override
Widget build(Buildcontext context) {
return new Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new Container(
padding: const EdgeInsets.all(16.0),
child: new TextField(
keyboardType: TextInputType.number,
controller: _controller,
decoration: new InputDecoration(
hintText: 'Zip Code',
),
onSubmitted: (string) {
return string;
},
),
),
new RaisedButton(
onPressed: () {
// use regex to test against user input
if (_controller.text != null && _controller.text.isNotEmpty) {
RegExp zipCodeRegExp = new RegExp(r"^(\d{5})$");
// if the user input validates...
if (zipCodeRegExp.hasMatch(_controller.text)) {
zipCode = _controller.text;
// need to perform database query here and return a string, not a Widget
} else {
// an else condition here
}
} else {
// an else condition here
}
}
}
),
],
);
}
</code></pre>
<p>Perhaps I'm not following the "mantra" of Flutter? I appreciate your consideration and input on this.</p>

Biztalk Design patterns : I am very new to Biztalk. I have been asked to create a application in Biztalk. I am facing some design level challenges.
Following are some of them:
1. Best approach in creating a project
How to crate Biztalk solution. Means how to create projects. Do we need to create different projects for Maps/Orchestation/pipelines and references. Which is the best approach to develop a project?
2. Can we check in a Biztalk project in TFS
How multiple people can work on a single Biztalk solution? Can it be checked in in TFS and multiple people can take it and work on it? How merging will work?
3. Code review
Is there any way to review a Biztalk package? What are the best practices?
Thanks in advance.

Fire Event from a C# library into a VB Winform program : <p>I am a C# programmer and have made a C# library for handling a tcp/ip chat.
Now I have the necessity to use it from a Server VB Winform program.
I am pretty sure that this is an easy solution problem but I have been struggling for days.
So in the C# I have that class:</p>
<pre><code>public class AsynchronousServer
{
public AsynchronousServer()
{
}
public delegate void ChangedEventHandler(string strMessage);
public static event ChangedEventHandler OnNotification;
public static event ChangedEventHandler OnAnswerReceived;
...
}
</code></pre>
<p>Now I have to focus on the server program:
if that VB program would have been in C# I would have written the code below for connecting the server on a button click</p>
<pre><code>public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void btnStart_Click(object sender, RoutedEventArgs e)
{
AsynchronousServer.OnNotification += AsynchronousServer_OnNotification;
AsynchronousServer.OnAnswerReceived += AsynchronousServer_OnAnswerReceived;
AsynchronousServer.StartServer(tbxIpAddress.Text,tbxPort.Text);
}
</code></pre>
<p>The same program in VB:</p>
<pre><code>Imports SocketLibrary
Public Class Form1
Private Sub btnStart_Click(sender As Object, e As EventArgs) Handles btnStart.Click
AsynchronousServer.OnNotification <--- member not present
AsynchronousServer.OnAnswerReceived <--- member not present
AsynchronousServer.StartServer(tbxIpAddress.Text, tbxPort.Text);<-----OK
End Sub
End Class
</code></pre>
<p>the problem is that the member AsynchronousServer.OnNotification is not present at all so I can't add the event.
I am aware that I might have to add the WithEvents keyword but try as I might I couldn't succed.</p>
<p>In short I have to connect that VB winform program to a C# library event which I can't see from my VB class.</p>
<p>Thanks for any help</p>

Note: Federation enabled on premise Skype for business is on a virtual setup and behind a company firewall.
I am confused as I can be found by the employees of other companies who also use Skype for Business then should not on premise Skype be able to connect to Microsoft Bot Connector. | 0debug |

HTTP/2 or Websockets for low latency client to server messages : <p>I have a requirement to have very low latency for client to server messages in my web application.</p>
<p>I have seen several posts on stackoverflow saying it would be preferable to use websockets instead of HTTP for this requirement, but it was quite some time ago.</p>
<p>Today, in 2018, with the progress of HTTP/2, is it still worth using websockets for this use case ? </p>

How to read a zip entry in a zip file, ad nauseum for c# or vb.net : While there is a response to this question using the java libraries (http://stackoverflow.com/questions/11287486/read-a-zip-file-inside-zip-file), I cannot find an example of this anywhere in c# or vb.net.
What I have to do for a client is use the .NET 4.5 ZipArchive library to traverse zip files for specific entries. Before anyone asks, the client refuses to allow me to use dotnetzip, because his chief architect has experience with that library and says it is too buggy to be used in a real application. He's pointed out a couple to me, and it doesn't matter what I think anyway!
If I have a zip file, that itself contains other zip files, I need a way of opening the inner zip files, and read the entries for that zip file. Eventually I will also have to actually open the zip entry for the zip in a zip, but for now I just have to be able to get at the zipentries of an inner zip file.
Here's what I have so far:
public string PassThruZipFilter(string[] sfilters, string sfile, bool buseregexp, bool bignorecase, List<ZipArchiveZipFile> alzips)
{
bool bpassed = true;
bool bfound = false;
bool berror = false;
string spassed = "";
int ifile = 0;
try
{
ZipArchive oarchive = null; ;
int izipfiles = 0;
if (alzips.Count == 0)
{
oarchive = ZipFile.OpenRead(sfile);
izipfiles = oarchive.Entries.Count;
}
else
{
//need to dig into zipfile n times in alzips[i] where n = alzips.Count
oarchive = GetNthZipFileEntries(alzips, sfile); <------ NEED TO CREATE THIS FUNCTION!
izipfiles = oarchive.Entries.Count;
}
while (((ifile < izipfiles) & (bfound == false)))
{
string sfilename = "";
sfilename = oarchive.Entries[ifile].Name;
//need to take into account zip files that contain zip files...
bfound = PassThruFilter(sfilters, sfilename, buseregexp, bignorecase);
if ((bfound == false) && (IsZipFile(sfilename)))
{
//add this to the zip stack
ZipArchiveZipFile ozazp = new ZipArchiveZipFile(alzips.Count, sfile, sfilename);
alzips.Add(ozazp);
spassed = PassThruZipFilter(sfilters, sfilename, buseregexp, bignorecase, alzips);
if (spassed.Equals(sISTRUE))
{
bfound = true;
}
else
{
if (spassed.Equals(sISFALSE))
{
bfound = false;
}
else
{
bfound = false;
berror = true;
}
}
}
ifile += 1;
}
}
catch (Exception oziperror)
{
berror = true;
spassed = oziperror.Message;
}
if ((bfound == false))
{
bpassed = false;
}
else
{
bpassed = true;
}
if (berror == false)
{
spassed = bpassed.ToString();
}
return (spassed);
}
So the function I have to create is 'GetNthZipFileEntries(List<ZipFileZipEntry>, sfile)', where the ZipFileZipEntry is just a structure that contains an int index, string szipfile, string szipentry.
I cannot figure out how read a zip file inside a zip file (or G-d forbid, a zip file inside a zip file inside a zip file...the 'PassThruZipFilter is a function **inside** a recursive function) using .NET 4.5. Obviously microsoft does it, because you can open up a zip file inside a zip file in explorer. Many thanks for anyone that can help.
**So, I truly need your help on how to open zip files inside of zip files in .NET 4.5 without writing to the disk**. There are NO examples on the web I can find for this specific purpose. I can find tons of examples for reading zip file entries, but that doesn't help. **To be clear, I cannot use a hard disk to write anything**. I can use a memory stream, but that is the extent of what I can do. **I cannot use the dotnetzip library**, so any comments using that won't help, but of course I'm thankful for any help at all. I could use another library like the Sharp zip libs, but I'd have to convince the client that it is impossible with .NET 4.5. | 0debug |

How to get uint8_t data of uint32_t : <p>I'm working with a microcontroller where the sensor I'm trying to interface sends uint8_t data. The issue is I can read the pin with a uint32_t function.</p>
<p>So I guess I can read the pin with the uint32_t, but I have to "extract" it. But I'm getting nonsense... </p>
<pre><code>uint32_t number = 429496729;
uint8_t x1 = (number >> (8*0)) & 0xff;
uint8_t x2 = (number >> (8*1)) & 0xff;
uint8_t x3 = (number >> (8*2)) & 0xff;
uint8_t x4 = (number >> (8*3)) & 0xff;
</code></pre>
<p>printing x3 for instance gives me "™". Same with x1. Whats going on here?</p>

How to perform double buffering with atomic pointers? : <p>Atomic newbie here. My code currently looks like this (simplified):</p>
<pre class="lang-cpp prettyprint-override"><code>std::atomic<Object*> object;
void thread_a()
{
object.load()->doSomething(); // (1)
}
void thread_b()
{
Object* oldObject = object.load();
Object* newObject = new Object();
// Update new object accordingly...
while (!object.compare_exchange_weak(oldObject, newObject));
delete oldObject;
}
</code></pre>
<p>In words, my idea is to let <code>thread_b</code> atomically swap the shared object (double-buffering), while <code>thread_a</code> performs some work on it. My question: can I safely assume that the shared object will be "protected" against data races while <code>thread_a</code> calls <code>doSomething()</code> on it, as done in (1)? </p>
