Custom Facebook Login button iOS : <p>I've just integrated the Facebook iOS SDK with my app, and the login works great. That said, the SDK doesnt seem to give me the option to customize my login button (it provides me with that ugly default button in the middle of the screen). I'm using Storyboards with my app - how can I go about hooking up my own button to their provided code? I've seen some older answers posted to Stack, but the FB documentation has since changed :/</p>
<p><strong>Viewcontroller.m</strong></p>
<pre><code> FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];
loginButton.center = self.view.center;
[self.view addSubview:loginButton];

Whats the point of running Laravel with the command 'php artisan serve'? : <p>I dont seem to understand why we need to run a Laravel app with <code>php artisan serve</code> vs just running it with <strong>Apache</strong> or <strong>nginx</strong>. I know that under development, we use artisan to fire up the site and after deployment to a server, you use the webserver to load up the site.</p>
<p>Whats the use of running the app in artisan in the first place?</p>

Unable to Finish connecting to SonarQube server : <p>This is going to sound like a ridiculous question, but using the SonarLint Eclipse plugin (v3.2.0) on the latest Eclipse (Oxygen), I am unable to add a new SonarQube server connection. </p>
<p>I am working behind a company firewall, but that doesnt appear to be an issue. I am following the steps <a href="http://www.sonarlint.org/eclipse/index.html" rel="noreferrer">here</a> and am able to successfully connect to our internal SonarQube instance, provide my credentials, but it is just on the final step, that the 'Finish' button does not seem to do anything, see screen below:</p>
<p><a href="https://i.stack.imgur.com/9BLeH.png" rel="noreferrer"><img src="https://i.stack.imgur.com/9BLeH.png" alt="enter image description here"></a></p>
<p>I appreciate there is probably some background processes need to run in order for this Finish to actually finish :) But this doesnt appear to be doing anything...Anyone else experience this issue?</p>
<p>Any before people ask, I've restarted Eclipse/laptop, uninstalled and reinstalled SonarLint plugin etc.</p>
<p>Thanks in advance!</p>

How to set onclick listener in xamarin? : <p>I'm quite new to C# and Xamarin and have been trying to implement a bottom sheet element and don't know how to correctly do it. I am using <a href="https://github.com/fabionuno/Cocosw.BottomSheet-Xamarin.Android" rel="noreferrer">Cocosw.BottomSheet-Xamarin.Android</a> library.</p>
<p>Here is my code:</p>
<pre><code>Cocosw.BottomSheetActions.BottomSheet.Builder b = new Cocosw.BottomSheetActions.BottomSheet.Builder (this);
b.Title ("New");
b.Sheet (Resource.Layout.menu_bottom_sheet)
</code></pre>
<p>Now i think i should use <code>b.Listener(...)</code>, but it requires an interface <code>IDialogInterfaceOnClickListener</code> as a paramater and i don't know how to do it in C# correctly.</p>
<p>In Java i could write </p>
<pre><code>button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
}
});
</code></pre>
<p>I tried doing this:</p>
<pre><code>class BottomSheetActions : IDialogInterfaceOnClickListener {
public void OnClick (IDialogInterface dialog, int which) {
Console.WriteLine ("Hello fox");
}
public IntPtr Handle { get; }
public void Dispose() {
}
}
</code></pre>
<p>and then this:</p>
<pre><code>b.Listener (new BottomSheetActions());
</code></pre>
<p>But it didnt work.</p>

How to open activity (incoming voip call) in Android 10 : <p>In Android 10 there apply new restrictions for apps.
We can no longer start an activity from background. While this may be fine for the majority of apps, it's a killing blow for voip-apps that need to show an incoming call after a push notification arrived.</p>
<p>According to this <a href="https://developer.android.com/guide/components/activities/background-starts" rel="noreferrer">https://developer.android.com/guide/components/activities/background-starts</a> there is a list of conditions that can be met to still allow opening an activity, but tbh I do not understand that fully (non-english-native here).</p>
<p><em>What I definitely know, is:</em></p>
<ul>
<li><p>I do not have any running activity, task, backstack and the like</p></li>
<li><p>The app is NOT EVEN RUNNING</p></li>
</ul>
<p><em>What I need to achieve:</em></p>
<ul>
<li>The FCM service of the app receives a push from our server and shall present the incoming call screen (over lock screen and all - just as it did with android 9 and below)</li>
</ul>
<p>What can I do to open an activity for an incoming voip call in android 10?
Over the lockscreen and all, just as a normal user would expect from a PHONE app.</p>
<p>Thanks in advance for any hints.</p>

Identity asp.net core 3.0 - IdentityDbContext not found : <p>My app broke with the 3.0 release of .NET core with reference errors for <code>IdentityDbContext</code>. I'm looking through documentation for Identity on core 3.0 but it implies that IdentityDbContext should be there. It's the only error I'm getting with a couple <code>DbContext</code> errors.</p>
<p>I have a pretty simple API, no MVC views, just a data server that gives back JSON objects. It's based on Identity so it has the users and roles and claims. And it's starting to take advantage of that. My main DbContext extends <code>IdentityDbContext<ApplicationUser></code> but after switching target platform to 3.0 after the upgrade, it says it doesn't exist and gives me compile errors. Has anyone run into this? Am I missing something? The migration and breaking changes pages don't seem to have anything addressing my issue.</p>
<p>DbContext looks like this:</p>
<pre class="lang-cs prettyprint-override"><code>using System;
using Microsoft.AspNetCore.Identity;
//using Microsoft.AspNetCore.Identity.EntityFrameworkCore; <- this no longer works either
using Microsoft.EntityFrameworkCore; //<- this I had to download as a package
using App.Constants;
using App.Models.Identity;
namespace App.Models
{
public class AppContext : IdentityDbContext<ApplicationUser> //<- error is right here
{
... my models
}
}
</code></pre>

Python : Get all Ints from inside Class Instance : I want to get all int types of a unknown class instance
If I have the following class
class myclass:
g_goodies = 0
g_stringer = "bob"
mylist = []
def __init__(self,goodies):
self.g_goodies = goodies
for x in range(0,10):
self.mylist.append(0)
And I have tried ..
def get_ints(self,inobject):
a = inspect.getmembers(inobject)
b = len(a)
print 'a:',a,' b:',b
print 'a type:',type(a),' b type:',type(b)
for x in range(0,b-1):
c = type(a[x])
print c
print "Hello World!\n"
mc = myclass(10)
pa = printanything()
print pa.get_ints(mc)
which gives me.
$python main.py
Hello World!
a: [('__doc__', None), ('__init__', <bound method myclass.__init__ of <__main__.myclass instance at 0x7f34ee9e80e0>>), ('__module__', '__main__'), ('g_goodies', 10), ('g_stringer', 'bob'), ('mylist', [0, 0, 0, 0, 0, 0, 0, 0, 0, 0])] b: 6
a type: <type 'list'> b type: <type 'int'>
<type 'tuple'>
<type 'tuple'>
<type 'tuple'>
<type 'tuple'>
<type 'tuple'>
None
So I simply want to be able to extract all the type <ints> in a class instance, all the type <string> in a class object etc.. The class is not known at run time.

I'm trying to get the length of my non list : I have this data I'm saving the player but I have one problem when I want to get the length of the "levels". I want to know how many levels there are with script so I don't need to keep changing an int variable and I'm also automating the process where the level gets added so I need to know how many levels there are.
PlayerData = new SetupData
{
// Level Data
Levels = new Levels
{
Level1 = new Level
{
Name = "First Level",
Progress = 0,
Completed = false
},
Level2 = new Level
{
Name = "Second Level",
Progress = 0,
Completed = false
},
},
// Character Data
Player = new Player
{
SelectedColor = 0,
Berries = 0
}
};
The problem is that this isn't a list or anything so I can't use `.Length`

Simple Array Map Issue - JavaScript : <p>I am having a simple problem with my Javascript program. The problem is when I try to map the lengths of nested arrays, the last array is being excluded.</p>
<pre><code>// the length doesnt matter, its N number of arrays
var exampleArray = [ [nested array], ..., [nested array] ];
function findArrayLengths() {
var arrayLengths = exampleArray.map(function(x) {
return x.length; });
return arrayLengths; }
</code></pre>
<p>My question is, is there something obvious I'm missing. Or should this code not in theory produce a new array that contains the lengths of all the nested arrays?</p>

Access 'Internal' classes with C# interactive : <p>Using the C# interactive console in VS2015, i want to access properties and classes marked as <code>internal</code>. Usually, this is done by adding the InternalsVisibleAttribute to the project in question. Ive tried adding csc.exe as a 'friend' assembly, but i still have the access problems.</p>
<ol>
<li>Is this the correct approach to access internal class members via the C# interactive console?</li>
<li>If it is, what dll/exe do i need to make the internals visible to?</li>

By default, Xcode 8 beta is using Swift 3 in Playgrounds and I cannot find a way to change that. Updating my code to Swift 3 is not an option unfortunately, because my code will be compiled on server with Swift 2.2 environment.</p>

How to manually lazy load a module? : <p>I've tried loading modules without router using <a href="https://angular.io/docs/ts/latest/api/core/index/SystemJsNgModuleLoader-class.html"><code>SystemJsNgModuleLoader</code></a>, but couldn't get it to work:</p>
<pre><code>this.loader.load(url).then(console.info);
</code></pre>
<p>I'm getting <code>Cannot find module xxx</code> for whatever string I use for URL (aboslute/relative urls/paths... tried many options). I looked through Router source code and couldn't find anything other then this <code>SystemJsNgModuleLoader</code>. I'm not even sure I should be using this...</p>
<hr>
<p>This question was asked just yesterday at <code>ng-europe 2016</code> conference - Miško & Matias answered:</p>
<blockquote>
<p><strong>Miško Hevery:</strong>
One just has to <em>get hold of the module</em>, from there you can get the hold of component factory and you can dynamically load component factory anywhere you want in the application. This is exactly what the router does internally. So it's quite strait forward for you to do that as well.</p>
<p><strong>Matias Niemelä</strong>
The only special thing to note is that on the [Ng]Module there's something called <code>entryComponents</code> and that identifies components that could be lazy loaded - that's the entry into that component set. So when you have modules that are lazy loaded, please put <em>the stuff</em> into <code>entryComponents</code>.</p>
</blockquote>
<p>...but it's not that strait forward without examples and poor docs on the subject (; </p>
<p>Anyone knows how to load modules manually, without using <code>Route.loadChildren</code>? How to <em>get hold of the module</em> and what exactly is <em>the stuff</em> that should go into <code>entryComponents</code> (I read <a href="https://angular.io/docs/ts/latest/cookbook/ngmodule-faq.html#!#q-entry-component-defined">FAQ</a>, but can't try without actually loading module)?</p>

Roslyn compiler optimizing away function call multiplication with zero : <p>Yesterday I found this strange behavior in my C# code:</p>
<pre><code>Stack<long> s = new Stack<long>();
s.Push(1); // stack contains [1]
s.Push(2); // stack contains [1|2]
s.Push(3); // stack contains [1|2|3]
s.Push(s.Pop() * 0); // stack should contain [1|2|0]
Console.WriteLine(string.Join("|", s.Reverse()));
</code></pre>
<p>I assumed the program would print <code>1|2|0</code> but in fact it printed <code>1|2|3|0</code>.</p>
<p>Looking at the generated IL code (via ILSpy) you can see that <code>s.Pop() * 0</code> is optimized to simply <code>0</code>:</p>
<pre><code>// ...
IL_0022: ldloc.0
IL_0023: ldc.i4.0
IL_0024: conv.i8
IL_0025: callvirt instance void class [System]System.Collections.Generic.Stack`1<int64>::Push(!0)
// ...
</code></pre>
<p><em>ILSpy decompilation</em>:</p>
<pre><code>Stack<long> s = new Stack<long>();
s.Push(1L);
s.Push(2L);
s.Push(3L);
s.Push(0L); // <- the offending line
Console.WriteLine(string.Join<long>("|", s.Reverse<long>()));
</code></pre>
<p>First I tested this initially under Windows 7 with Visual Studio 2015 Update 3 with both Release mode (<code>/optimize</code>) and Debug mode and with various target frameworks (4.0, 4.5, 4.6 and 4.6.1). In all 8 cases the result was the same (<code>1|2|3|0</code>).</p>
<p>Then I tested it under Windows 7 with Visual Studio 2013 Update 5 (again with all the combinations of Release/Debug mode and target framework). To my surprise the statement is here <em>not</em> optimized away and yields the expected result <code>1|2|0</code>.</p>
<p>So I can conclude that this behavior is neither dependent on <code>/optimize</code> nor the target framework flag but rather on the used compiler version.</p>
<p>Out of interest I wrote a similar code in C++ and compiled it with the current gcc version. Here a function call multiplied with zero is not optimized away and the function is properly executed.</p>
<p>I think such an optimization would only be valid if <code>stack.Pop()</code> were a pure function (which it definitely isn't). But I'm hesitant to call this a bug, I assume it's just a feature unknown to me?</p>
<p>Is this "feature" anywhere documented and is there an (easy) way to disable this optimization?</p>

How do I make a div tag display if I have it hidden on CSS using Javascript? : <p>In CSS I have a div tag that is like a comment section, but I want it hidden until the user clicks on the comment image. How do I make the div display when the user clicks on it using JavaScript?</p>

Why does the std::copy_if signature not constrain the predicate type : <p>Imagine we have the following situation: </p>
<pre><code>struct A
{
int i;
};
struct B
{
A a;
int other_things;
};
bool predicate( const A& a)
{
return a.i > 123;
}
bool predicate( const B& b)
{
return predicate(b.a);
}
int main()
{
std::vector< A > a_source;
std::vector< B > b_source;
std::vector< A > a_target;
std::vector< B > b_target;
std::copy_if(a_source.begin(), a_source.end(), std::back_inserter( a_target ), predicate);
std::copy_if(b_source.begin(), b_source.end(), std::back_inserter( b_target ), predicate);
return 0;
}
</code></pre>
<p>Both the call to <code>std::copy_if</code> generate a compile error, because the correct overload of <code>predicate()</code> function cannot be infered by the compiler since the <code>std::copy_if</code> template signature accepts any type of predicate:</p>
<pre><code>template<typename _IIter,
typename _OIter,
typename _Predicate>
_OIter copy_if( // etc...
</code></pre>
<p>I found the overload resolution working if I wrap the <code>std::copy_if</code> call into a more constrained template function:</p>
<pre><code>template<typename _IIter,
typename _OIter,
typename _Predicate = bool( const typename std::iterator_traits<_IIter>::value_type& ) >
void copy_if( _IIter source_begin,
_IIter source_end,
_OIter target,
_Predicate pred)
{
std::copy_if( source_begin, source_end, target, pred );
}
</code></pre>
<p>My question is: why in the STL is it not already constrained like this? From what I've seen, if the <code>_Predicate</code> type is not a function that returns <code>bool</code> and accepts the iterated input type, it is going to generate a compiler error anyway. So why not putting this constrain already in the signature, so that overload resolution can work?</p>

Can you omit the return type in main function? : <p>Are there some special rules with respect to the declaration of the <code>main</code> function?</p>
<p>According to <a href="http://ideone.com/eEoa8n">ideone</a> this is legal C++:</p>
<pre><code>main() // As opposed to int main()
{
return 0;
}
</code></pre>
<p>On the other hand, normal functions do not seem to have the privilege to avoid the return type:</p>
<pre><code>f(){}
int main()
{
return 0;
}
</code></pre>
<p>Gives the error:</p>
<blockquote>
<p>prog.cpp:1:3: error: ISO C++ forbids declaration of 'f' with no type
[-fpermissive] f(){} ^</p>
</blockquote>
<p>Is the <code>main</code> function special in this case?</p>

Adding Strings to a list from textfield : im triying to add "players" to a list (observablelist) throug a textfield input.

juga.setNombre(jugador);
colJugador.setCellValueFactory(new PropertyValueFactory<>("nombre"));
t_tabla.setItems(lista_Jugadores);
t_tabla.refresh();
System.out.println(lista_Jugadores);
}
problem is that eveytime i enter a new name in the textfield, the list keep only the last value, forgeting the rest.
How can i keep all the records? i dont want to use a DB (i have the same system with db and it works good).

<p>when i cout to see if it works the number that i wanted to delete is still there.

12,15,20,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 <br>
I used cout to see if there was a problem with the condition however it runs if x is in the array.
Here is the output after, even if x is in the array:<br>

colnames(dummies) <- c("a","b", "c", "d", "e", "f")
</code></pre>
<p>I have a matrix with dummies</p>
<pre><code>> dummies
a b c d e f
[1,] 0 0 0 0 1 0
[2,] 0 0 1 0 0 0
[3,] 1 0 0 0 0 0
[4,] 0 0 0 0 0 1
[5,] 0 1 0 0 0 0
[6,] 0 0 0 1 0 0
</code></pre>
<p>I know that my dummies are related in that line 1 is grouped with 2, 3 with 4, and 5 with 6. I want to split each dummy code(1) between those in the same group on the same line as above:</p>
<pre><code>> dummies
a b c d e f
[1,] 0.0 0.0 -0.5 0.0 0.5 0.0
[2,] 0.0 0.0 0.5 0.0 -0.5 0.0
[3,] 0.5 0.0 0.0 0.0 0.0 -0.5
[4,] -0.5 0.0 0.0 0.0 0.0 0.5
[5,] 0.0 0.5 0.0 -0.5 0.0 0.0
[6,] 0.0 -0.5 0.0 0.5 0.0 0.0
</code></pre>
<p>To achieve this, I do the following:</p>
<pre><code>dummies <- ifelse(dummies==1, 0.5, 0)
for (i in 1:nrow(dummies)){
column = which(dummies[i,] %in% 0.5)
if (i %% 2 != 0) {
dummies[i+1, column] <- -0.5
} else {
dummies[i-1, column] <- -0.5
}
}
</code></pre>
<p>My question is whether I could achieve this with vectorised code. I cannot figure out how to use <code>ifelse</code> in this case because I cannot combine it with the line indexing to find the <code>0.5</code> on each line. </p>

IntelliJ annotate vs git blame : <p>I am using IntelliJ's annotate feature to see in the editor who last changed a line in a file. </p>
<p>Now I am using JGit to read the same annotations and they differ. For me it seems that Intellij checks that a line has not been changed between commits and still uses the old commit message. JGit does not see it and so makes an other message. </p>
<p>Can anybody confirm that the behavior of JGit blame and IntelliJ differs? Whats the reason and how can I force IntelliJ to behave the same like JGit? Maybe IntelliJ ignores whitespace changes?</p>
<p>I am using IntelliJ 15.0.1 and JGit 4.1.1</p>

Fragment not getting replaced on click : <p>I have an <code>Activity</code> which consists of a <code>Fragment</code>. The <code>Fragment</code> has two ViewGroups (LinearLayouts),which I want to use like buttons to change the layout of that very <code>Fragment</code>. </p>
<p>I am facing two problems in this:<br>
1. The two LinearLayouts don't give any visual touch-feedback (ripple animation) even when <code>clickable="true"</code> and <code>android:background="?attr/selectableItemBackground"</code> is set.<br>
2. The <code>Fragment</code> doesn't get replaced by a new <code>Fragment</code> even though <code>onClickListener</code> for the two <code>LinearLayout</code> works (checked using a <code>Snackbar</code>).<br>
3. In the statement <code>fragmentManager.beginTransaction().add(R.id.fragment_linearlayout,sb_qa_defaultFragment).commit();</code>, I read on SO that the first argument of add should not be the id of the <code>fragment</code> itself but the <code>container</code> of the <code>fragment</code>.

adb.exe spawning many process instances : <p>I'm new to developing for Android and have been tasked with helping the development of some React Native based Android application. I have a working setup in which an emulated Android device can run this application. However, when starting the emulator, the process <code>adb.exe</code> repeatedly gets spawned in the background at a rate of about 1 process per second. These processes seemingly take no/very little memory (144K according to the Task Manager), but over time, this still adds up to a massive list of processes (nearing 3000 at the time of writing) taking up quite a bit of memory (which is already scarce thanks to a fairly heavy development toolchain).</p>
<p>Closing the emulator does not automatically terminate these processes. The only way I have found so far that works is by using <code>taskkill /IM /F</code>.</p>
<p>Is this expected behaviour? If not, how could I begin with tracking down the reasons for behaviour.</p>
