What will printf do when not enough arguments are passed? : <p>Let's say I used <code>printf</code> without passing enough arguments to match the format specifiers: </p>
<pre><code>#include <stdio.h>
int main(void) {
printf("missing argument: %s\n");
}
</code></pre>
<p>Are there any guarantees on what the result will be?<br>
On my machine, nothing gets printed at all.<br>
Is this always the case, or is there a potential for it to print the string with an resolved specifier? </p>
<p>for example:
<code>missing argument: %s</code> </p>
<p>or:
<code>missing argument:</code></p>

What type of ML algorithm / model should I use for prediction? : <p>I apologize this might be a poorly asked question, Im looking for more of a point in the right direction to start research. </p>
<p>So say I have large sets of Array data. Ill be easiest to give an example:</p>
<pre><code>[{a: 1}, {h: 3}, {r:7}, {p: 2}]
[{y: 4}, {p: 3}, {w: -3}, {u: 54}]
[{l: -9}, {h: 5}, {r: 9}, {p: 5}]
[{o: -5}, {f: 4}, {i: 0}, {t: 1}]
[{a: 1}, {h: 2}, {r:5}, {p: 2}]
</code></pre>
<p>Okay so the keys of the objects doesn't really matter. What I want to be able to do is train a model on these objects by saying which list is 'good' and which list is 'bad'. From the example data above, if the 1st , 3rd, 5th list is 'good' and the 2nd and 4th are 'bad' I want the model to be able to identify that they all share the similar factors of h, r, p, that h, r, p are positive value (or negative or something of that form), and that they are in the same order in the list. so for example if I were to pass in <code>[{h: 2}, {a: 1}, {p: 2}, {r:5}]</code> as bad I would be able to separate it out as a different order. So basically I want to be able to identify what is most likely to results in a 'good' list be comparing similarities.</p>

How does reloadOnChange of Microsoft.Extensions.Configuration work for appsettings.json : <p>In two projects (a .NET Core Web API and a .NET Core WindowsService) I am using appsettings.json for the configuration. </p>
<pre><code> var configuration = new ConfigurationBuilder()
.SetBasePath(System.IO.Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
.AddEnvironmentVariables()
.Build();
</code></pre>
<p>In both I have the reloadOnChange set to true and using it as injected <code>IOptions</code> via dependency injection. Within the web api into the controller classes and within the service into the classes that use the settings.</p>
<p>Unfortunatly I experience that the values do not change when the appsettings.json changes.</p>
<p>On the web api I created a controller to just return a string value from the config and this stays the same as on startup.</p>
<p>So my questions:</p>
<ol>
<li>Anyone knows if that should work out of the box (at least in the web api)?</li>
<li>Anything I have to do that it works?</li>

Delphi - How to use Alt Codes? : Delphi RIO - I need to build a string which contains Alt Codes, specifically Alt-16 (Arrow symbol). I have a line of text (aka a string). I append a Carriage return, then want an ARROW symbol and the new line of text. This line will then be passed to PPT. If I manually go into PPT, into a text box, I can hit Alt+16, and get the arrow symbol. This is what I programatically want to do.
Alt symbols found [here][1].
Here is what I am trying, but it gives me a totally different symbol.
line := line + #13 + Chr(VK_MENU) + #16 + NewLine;
How do I build a string with ALT Codes as part of the string?

React.js: Set innerHTML vs dangerouslySetInnerHTML : <p>Is there any "behind the scenes" difference from setting an element's innerHTML vs setting the dangerouslySetInnerHTML property on an element? Assume I'm properly sanitizing things for the sake of simplicity.</p>
<p>Example:</p>
<pre><code>var test = React.createClass({
render: function(){
return (
<div contentEditable='true' dangerouslySetInnerHTML={{ __html: "Hello" }}></div>

},
render: function(){

<div contentEditable='true' ref='test'></div>
);
}
});

How to host multiple .NET Core apps under same url : <p>I am building a few web sites in asp.net core (multiple user interface applications and a web api app). They all work together, utilising the web api. For the purpose of my question we'll call them App1, App2 and App3. I am hosting my websites in IIS.</p>
<p>Typically, in the old .net Framework (4.5.1), I would have one website in IIS, with multiple web apps to host my multiple applications. Like so:</p>
<ul>
<li><p>WebSite1 - running on port 443</p>
<ul>
<li><p>App1</p></li>
<li><p>App2</p></li>
<li><p>App3</p></li>
</ul></li>
</ul>
<p>If the website (WebSite1) runs on port 443 (using the SSL cert), that means all apps are accessible via one domain url as follows:</p>
<ul>
<li><p><a href="https://www.myapp.com/App1/" rel="noreferrer">https://www.myapp.com/App1/</a></p></li>
<li><p><a href="https://www.myapp.com/App2/" rel="noreferrer">https://www.myapp.com/App2/</a></p></li>
<li><p><a href="https://www.myapp.com/App3/" rel="noreferrer">https://www.myapp.com/App3/</a></p></li>
</ul>
<p>With different app names at the end of the url to identify them.</p>
<p>When hosting the new asp.NET Core applications, I host in IIS as well, and following the documentation for asp.NET Core web site deployment, I host each .NET Core web app in a different site within IIS. </p>
<p>As I have one domain name for all my sites, for example, <a href="https://www.example.com" rel="noreferrer">https://www.example.com</a> (I'm using an SSL cert), I have to give the other websites different ports. So I end up with something like this:</p>
<ul>
<li><p>WebSite1 - running on port 443</p></li>
<li><p>WebSite2 - running on port 444</p></li>
<li><p>WebSite3 - running on port 445</p></li>
</ul>
<p>All of these apps are then accessible via these domain name urls:</p>
<ul>
<li><p><a href="https://www.example.com/" rel="noreferrer">https://www.example.com/</a> or <a href="https://www.example.com:443/" rel="noreferrer">https://www.example.com:443/</a></p></li>
<li><p><a href="https://www.example.com:444/" rel="noreferrer">https://www.example.com:444/</a></p></li>
<li><p><a href="https://www.example.com:445/" rel="noreferrer">https://www.example.com:445/</a></p></li>
</ul>
<p>How do I host asp.NET Core applications all under one website as different "Applications", meaning they resolve to the same domain name url (<a href="https://www.example.com" rel="noreferrer">https://www.example.com</a> and the forward slash app name identifies which app we want)? OR alternatively, how do I take what I have configured now with the ports and route them all so App1 is default for example.com/, App 2 is example.com/app2/, and App 3 is example.com/app3/?</p>
<p>Am I looking at this .NET Core deployment completely the wrong way?</p>
<p>Thanks in advance for any pointers!</p>

How to make a curl request to get data from clickhouse database | Go : I'm trying to make a cURL request to get data from clickhouse database using Go, I don't have too much experience with cURL and not sure how to get the returned value by the query
This is what I have:
reader := strings.NewReader("SELECT COUNT(*) FROM system.tables WHERE database = 'local' AND name = 'persons'")
request, err := http.NewRequest("GET", "http://localhost:8123", reader)
if err != nil {
fmt.Println(err)
}
client := &http.Client{}
resp, err := client.Do(request)
if err != nil {
fmt.Println(err)
}
fmt.Println("The answer is: ", resp.Body)
The expected output should be a number (1 means table exist and 0 means that doesn't exist) but I'm getting in `resp.Body` this output:
The answer is: &{0xc4201741c0 {0 0} false <nil> 0x6a9bb0 0x6a9b20}
Any idea to get just the value of the query? | 0debug |

Make Segue programmatically in Swift : <p>I have two VCs: VC1 and VC2.
In VC1, I have a <code>finish button</code> which I programmatically made and a <code>result array</code> I want to pass to VC2.</p>
<p>I know how to make Segue in Storyboard, but I cannot do that at this moment since the <code>finish button</code> is programmatically made. </p>
<p>If I want to pass result array using segue, is there a way to make the segue programmatically? If this is not possible, should I just present VC2 using <code>presentViewController</code> and set a delegate to pass the <code>result array</code>?</p>

Laravel ShouldQueue How Does It Work : <p>I know how to use <code>ShouldQueue</code> my question is about why does it work the way it does.</p>
<p>I need to edit how my <code>new Job</code> is stored in the database, and therefore am digging through Laravel's internals.</p>
<p>The job I want to edit is launched from the following event listener:</p>
<pre><code><?php
namespace App\Listeners;
use App\Events\NewMail;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use App\Jobs\SendEmail;
use Carbon\Carbon;
class NewMailListener implements ShouldQueue
{
/**
* Create the event listener.
*
* @return void
*/
public function __construct()
{
//
}
/**
* Handle the event.
*
* @param NewMail $event
* @return void
*/
public function handle(NewMail $event)
{
$addressee = $event->user->name;
$address = $event->user->email;
$type = "NewMail";
$job = (new SendEmail($type,$addressee,$address))->delay(Carbon::now()->addMinutes(10));
dispatch($job);
}
}
</code></pre>
<p>What I don't understand is how the <code>ShouldQueue</code> magic works, because in the <a href="https://github.com/illuminate/contracts/blob/5.3/Queue/ShouldQueue.php" rel="noreferrer">source code</a> it appears to do nothing.</p>
<pre><code><?php
namespace Illuminate\Contracts\Queue;
interface ShouldQueue
{
//
}
</code></pre>
<p>I understand it is a <a href="https://laravel.com/docs/5.5/contracts" rel="noreferrer">contract</a> but it's not defining anything... so what it is doing exactly? Is there some auto-loading happening from the namespace?</p>
<p>I wasn't sure what an interface was exactly, so I looked at this: <a href="http://php.net/manual/en/language.oop5.interfaces.php" rel="noreferrer">PHP Docs: Interfaces</a> and came away with the impression that even if it is for decoupling, and interface should be defining something, which I don't see in <code>ShouldQueue</code>.</p>
<p>The top comment on that PHP docs page says this:</p>
<blockquote>
<p>An INTERFACE is provided so you can describe a set of functions and
then hide the final implementation of those functions in an
implementing class. This allows you to change the IMPLEMENTATION of
those functions without changing how you use it.</p>
</blockquote>
<p>But where is this description of functions here?</p>
<p>PS - I know this interface/contract is being used to queue the event listener itself, not the job that I want to edit. But I'm hoping understanding how the queue interacts with the event listener will better inform me as to how it works for the jobs.</p>

How to use R 3.3.2 to add index column to dataframe based on column value? : <h2>Problem</h2>
<p>How to create a index column in a dataframe for R given the categorical values in a column? </p>
<p>In other words, assume we have a dataframe as follows: </p>
<pre><code>id cat
1 A
2 A
3 A
4 B
5 B
6 C
7 C
8 C
9 C
10 C
</code></pre>
<p>How can we create a column called rank that does the following: </p>
<pre><code>id cat rank
1 A 1
2 A 2
3 A 3
4 B 1
5 B 2
6 C 1
7 C 2
8 C 3
9 C 4
10 C 5
</code></pre>
<h2>Attempts</h2>
<p>Assume the dataframe is called <code>df</code>. I tried the following: </p>
<ul>
<li>aggregate(df, by = c('A','B','C'), length)</li>
<li>Starting writing a custom function to work with lapply, but ran into too many boundary cases. </li>
</ul>
<p>This gave me mismatched length errors. Obviously the idea here was to get the count for each group and then write a function that can take the row value with lapply and keep counting until I hit the length. </p>
<h2>Additional Notes</h2>
<p>I am thinking about abandoning the above ideas and splitting the dataframe into separate smaller dataframes by cat value. I will then create a rank variable for each dataframe that is indexed. The challenge then becomes, what is a good way to combine all the dataframe values back into one dataframe with the new rank column? </p>
<p>None of this is sitting quite right with me though. Frankly, my gut says I'm doing this all wrong. Am I making this too hard? Is there a package or R trick that does this easily? I apologize if this seems silly, but I cannot in good conscious proceed further without seeking the advice of R programmers more skilled than me. </p>

VSTS release pull request build trigger : <p>My team are using the VSTS Build & Release mechanism, combined with pull request branch safety settings, so that code can only be merged in when a pull request is completed.</p>
<p>We are experiencing something odd though, in that when a pull-request is created (and a build is spawned to prove the commit) - the completion of this build triggered by the pull request also indirectly triggers a release because we have a release trigger setup.</p>
<p>This in itself is probably ok, but then what also happens is upon 'completing' the pull request, another build & release cycle takes place!</p>
<p>Is there a way of making VSTS release triggers only kick in when the pull request is completed and merged into the release branch? </p>
<p>Thank you!</p>

Are there extensions to let optimizers assume const-ref parameters will stay const? : <p>Related to my former question: <a href="https://stackoverflow.com/questions/49117489/are-compilers-not-allowed-to-assume-const-ref-parameters-will-stay-const">Are compilers not allowed to assume const-ref parameters will stay const?</a></p>
<p>My new question is: Is there compiler-specific, non-standard extensions or syntax to tell GCC/Clang/MSVC that an object is not writable? For example, here's some fake-ish code I'd like to be able to write:</p>
<pre><code>void f(const int& i) {
// At this point, compiler doesn't know if "i" can be mutated or not,
// so it assumes it can
// Fake-ish -- compiler now assumes "i" cannot be mutated and optimizes accordingly
__assume(readonly i);
// ...

C ampersand operator from command line : I need to develop a client and server program with using sockets. My program should get port number from the command line. I saw an example which says "myprogram 2454 &"
I wonder what that & means there.

Flutter nested StreamBuilders causing Bad state: Stream has already been listened to : <p>I'm trying to build a Flutter app using the BLoC pattern described in the video <a href="https://www.youtube.com/watch?v=PLHln7wHgPE&feature=youtu.be" rel="noreferrer" title="Flutter / AngularDart – Code sharing, better together (DartConf 2018)">Flutter / AngularDart – Code sharing, better together (DartConf 2018)</a></p>
<p>A BLoC is basically a view model with <code>Sink</code> inputs and <code>Stream</code> outputs. In my example it looks a bit like this:</p>
<pre><code> class BLoC {
// inputs
Sink<String> inputTextChanges;
Sink<Null> submitButtonClicks;
// outputs
Stream<bool> showLoading;
Stream<bool> submitEnabled;
}
</code></pre>
<p>I have the BLoC defined in a widget near the root of the hierarchy and it is passed down to widgets beneath it, including nested <code>StreamBuilders</code>. Like so:</p>
<p><a href="https://i.stack.imgur.com/RQlJL.png" rel="noreferrer"><img src="https://i.stack.imgur.com/RQlJL.png" alt="BLoC widget hierarchy"></a></p>
<p>The top <code>StreamBuilder</code> listens to a <code>showLoading</code> stream on the BLoC so that it can rebuild to show an overlaid progress spinner. The bottom <code>StreamBuilder</code> listens to a <code>submitEnabled</code> stream to enable/disable a button.</p>
<p>The problem is whenever the <code>showLoading</code> stream causes the top <code>StreamBuilder</code> to rebuild the widget it rebuilds nested widgets too. This in itself is fine and expected. However this results in the bottom <code>StreamBuilder</code> being recreated. When this happens it attempts to re-subscribe to the existing <code>submitEnabled</code> stream on the BLoC causing <code>Bad state: Stream has already been listened to</code></p>
<p>Is there any way to accomplish this without making all of the outputs <code>BroadcastStreams</code>?</p>
<p>(There is also a chance that I'm fundamentally misunderstanding the BLoC pattern.)</p>
