Android Studio - Assigning multiple value to ManifestPlaceholders in Gradle : <p>I have two environment of my project one <strong>Prod</strong> another one is <strong>Staging</strong>. So whenever I have to build any of the environment, I have to change multiple keys like map key, label name and other things in manifest. So I have searched and find out some of the solutions and <strong>manifestPlaceholders</strong> is one of them. </p>
<p>Now what I want to do is to assign multiple value in <strong>manifestPlaceholders</strong>. So can I put multiple values in it and yes then how to put multiple values in it. Here is the code for the <strong>manifestPlaceholders</strong></p>
<pre><code>buildTypes {
debug {
manifestPlaceholders = [ google_map_key:"your_dev_key"]
}
release {
manifestPlaceholders = [ google_map_key:"prod_key"]
}
}

Do I need bcsymbolmap files created by Carthage : <p>I am using Carthage dependency manager in my iOS project.
I have the <code>Carthage/build</code> folder in my repository to always have ready to go built frameworks when checking out the repo.</p>
<p>I am wondering what the <code>bcsymbolmap</code> files in the build folder are for. Quite a few of them are created with every <code>carthage update</code>. </p>
<p>Do I need to keep these files? Should I have them in my repository? </p>

Flexbox -how to get first child 50% widht and 100% height while stacking remaining children? : <p>I can't do much with the markup, if I could I'd just add 2 containers side by side. Basically it is a UL that looks like this:</p>
<pre><code><ul>
<li>one</li>
<li>two</li>
<li>three</li>
<li>four</li>
</ul>
</code></pre>
<p>I need the first child to fill the height of the container at 50% width. The remaining children should have 50% width but auto height and stack on the right side of the container.</p>

How to completely delete a commit from GitHub? : <p>On GitHub, I forked a repositary and cloned on my PC. Then, for testing purpose, I edited a file, made a commit and pushed it to GitHub. But now I would like to completely delete this commit.</p>
<p>I did the following:</p>
<pre><code>git reset --hard <sha1_of_previous_commit>
git push --force
</code></pre>
<p>It looked OK, but my commit was still accessible on GitHub by URL with SHA1 of my commit. So I deleted the repositary on GitHub, then the URL was saying Not Found. </p>
<p>But if I fork the same repositary again, my commit is again accessible by this URL. Please help me, how the hell I can get rid of this commit?</p>

C scanf ignored when invalid input : <p>I wrote this code, and all it meant to do is input ints until a negative is entered:</p>
<pre><code>int result = 0, input_number = 0;
while(input_number >= 0){
printf("Please enter students IDs(negetive to stop)= ");
result = scanf("%d", &input_number);
if(result != 1){
printf("Invalid input! try again...\n");
continue;
}
}
</code></pre>
<p>When the input is an int- everything works fine,</p>
<p>But when entering a char (any char the is not int),</p>
<p>The loop becomes endlessly and scanf doesn't request any input anymore.</p>
<p>DO NOT suggest I use a replacement for scanf cause it's a work for school,
and scanf must be used.</p>
<p>After entering char output:</p>
<pre><code>Please enter students IDs(negetive to stop)= 4
Please enter students IDs(negetive to stop)= 5
Please enter students IDs(negetive to stop)= r
Please enter students IDs(negetive to stop)= Invalid input! try again...
Please enter students IDs(negetive to stop)= Invalid input! try again...
Please enter students IDs(negetive to stop)= Invalid input! try again...
Please enter students IDs(negetive to stop)= Invalid input! try again...
Please enter students IDs(negetive to stop)= Invalid input! try again...

Can I make the pytest doctest module ignore a file? : <p>We use pytest to test our project and have enabled <code>--doctest-modules</code> by default to collect all of our doctests from across the project.</p>
<p>However there is one <code>wsgi.py</code> which may not be imported during test collection, but I cant get pytest to ignore it.</p>
<p>I tried putting it in the <code>collect_ignore</code> list in <code>conftest.py</code> but apparently the doctest module does not use this list.</p>
<p>The only thing that does work is putting the whole directory of <code>wsgi.py</code> into <code>norecursedirs</code> in the pytest config file, but this obviously hides the whole directory, which I don't want.</p>
<p>Is there a way to make the doctest module ignore just a certain file?</p>

C++ Iterating through files in a directory: Is it bad practice? : <p>The question has been asked many times here: "How do I iterate through files in a directory in c++?"</p>
<p>I've seen the responses, typically suggesting to use an external library (usually boost filesystem) to handle this and the OS differences in implementation.</p>
<p>My question is: why? Why is this so difficult?
I'm new to the language and can't help but feel that I'm trying to overstep the bounds of idiomatic c++.</p>
<p>Is it more appropriate to implement a single file solution and use another language to implement the file iteration?</p>

About a book application program in Java using linked list : This is book Application code. I am making a code in which the program shows some options like insert Book, delete Book etc. Program asks us to enter certain details about a book by Insert method. Once I enter details it goes back and show the options again. When I choose search method it asks me search by title or search by ISBN or search by author?

How can I remove duplicated code between classes? : <p>I have 2 class: RecursiveFibonacci and MemorizedRecursiveFibonacci. This is what I have so far. </p>
<p><strong>RecursiveFibonacci Class</strong></p>
<pre><code>public class SimpleRecursiveFibonacci {
public BigInteger fibonacci(int n) {
if(n < 2) {
return BigInteger.ONE;
}
return fibonacci(n - 2).add(fibonacci(n - 1));
}
}
</code></pre>
<p><strong>and MemorizedRecursiveFibonacci Class</strong></p>
<pre><code>public class MemoizedRecursiveFibonacci {
private Map<Integer, BigInteger> cache = new HashMap<>();
public BigInteger fibonacci(int n) {
if(n < 2) {
return BigInteger.ONE;
}
if(!cache.containsKey(n)){
BigInteger currentFibonacci = fibonacci(n - 2).add(fibonacci(n - 1));
cache.put(n, currentFibonacci);
}
return cache.get(n);
}
}
</code></pre>
<p>As I see, there are some duplicated code in MemorizedRecursiveFibonacci Class</p>
<pre><code> if(n < 2) {
return BigInteger.ONE;
</code></pre>
<p>and </p>
<pre><code> BigInteger currentFibonacci = fibonacci(n - 2).add(fibonacci(n - 1));

Landing Page Redirect Based on Location Choice (Cookies?) : <p>Before someone gets upset that I haven't included code, please understand that it is because I am not sure what the best practice would be.</p>
<p>I have a site that operates in 3 cities specifically, and also a nation-wide version. This is an eCommerce site that has different subdomains (essentially 3 different sites, but the ability to manage products specifically based on location.)</p>
<p>What I need is for the user to select their city or location preference (say New York, Chicago, Detroit or Entire US) and have that information stored so that the next time they return they don't have to reselect their preferred location.</p>
<p>Of course, for UX purposes the ability to change location is available in a Top Nav menu bar should they temporarily be in the other city.</p>
<p>Can IPs be targeted accurately to exact city? Should this be automated or should they be able to choose?</p>
<p>My question is : What is the best practice for this? Are there any consequences to this setup? What should be used? JavaScript? JQuery? PHP?</p>
<p>If there are no major negatives, where should I start to implement this?</p>

When nodeType() used in object behaves different in jQuery versions '1.11.2' and '3.1.1' : <p>I am eager to know why the jQuery versions '1.11.2' and '3.1.1' behaves in two different ways while using nodeType() function in jQuery object.</p>
<p>To illustrate this, I have two fiddle links for these two versions. </p>
<p>jquery-1.11.2<br>
<a href="https://jsfiddle.net/38z9m9j9/9/" rel="noreferrer">https://jsfiddle.net/38z9m9j9/9/</a></p>
<p>jquery-3.1.1<br>
<a href="https://jsfiddle.net/38z9m9j9/8/" rel="noreferrer">https://jsfiddle.net/38z9m9j9/8/</a></p>
<p>And in this, I have an condition that, </p>
<pre><code>this.options.data == data.colors[0];
</code></pre>
<p>This gets equal only in version '1.11.2' on using '<strong>nodeType()</strong>' function for object 'this.options.data.colors[0]' where as not working in '3.1.1'. So, how does the 'nodeType()' works here in '1.11.2'?</p>
<p>Thanks in advance.</p>

Simple code help needed for " http://12.13.14.15/table1.php?Name=Billy&Number=6 " : I am in need of some help, please? I can successfully do a MySQL query using:
IP_Address/fund_list.php?Id_Number=555666
$ID = $_GET['Id_Number'];
$sql = "SELECT * FROM fund_list WHERE Number = ".$ID;
-----------------------------------------
Now I want to use 2 different things in my web call. Like:
IP_Address/fund_list.php?Id_Number=555666&Name=Billy
But I don't know how to write the 'get' line below.
$ID = $_GET['Id_Number'] & $Name = $_GET['Name']; <-- Does not work
I would think the SQL select statement would be:
$sql = "SELECT * FROM fund_list WHERE TheNumber = .$ID AND TheName = .$Name";
All the things I look up online, the syntax is overly confusing, I can't dissect it and make something work. Thank you.

Sublime Text 3 - Limit images to viewsize : <p>I'm working on a Sublime Text 3 plugin, which displays images in a view. Those images are created by an jupyter kernel, therefore the size of the images depend on the code producing them. Since I create really big images, they are to big to fit in the view.</p>
<p>I would like to limit the size to the image to the size of the view, like scale it to 100% of the view size. Is there any way to get the size of the current view and add this to the minihtml implementation of ST3?</p>
<p>I've tested width: 100% which just used a fraction of the actual views size. </p>

Protractor: Support for the Firefox >=48 : For quite sometime now I have been trying to run protractor with Firefox(Windows) v48 and above to run my AngularJS application.
However, as per [protractor docs][1]
> WebDriver support fr Firefox has changed recently, and FireFox version
> 48 does not work properly with the current tools. For the moment, we
> recommend testing against FireFox 47
This information was updated 3 years ago and nothing seems to have been done afterwards.
**Versions**
- OS - Windows 10 64-bit
- Protractor - 5.4.2
- Firefox - 68
- selenium-stanalone-server: 2.53.1
- AngularJS - 1.6.9
I did raise an issue recently on [github][2] for the same, but it has not received traction yet.
I would like to know if anyone has been able to get around the issue for Windows.

Visual Studio 2017 References vs Dependencies : <p>I have a .NET Core solution in visual studio 2017 that is building against the .NET 4.7 framework. </p>
<p>In the main web application there is a dependencies menu that breaks down references into logical categories (Analyzers, Assemblies, NuGet, Projects).</p>
<p><a href="https://i.stack.imgur.com/twf7f.png" rel="noreferrer"><img src="https://i.stack.imgur.com/twf7f.png" alt="Dependencies Menu"></a></p>
<p>In the helper project it only has a references menu with everything jumbled inside. Is there a way to get the same treatment here as the web application got?</p>

ggplot(data2, aes(fill=condition, y=value, x=specie)) +
geom_bar( stat="identity", position="fill")
But my data looks like:
A B
Group C 4 5
D 1 2
The plot should tell me: What's the percentage of A is in Group C? What's the percentage of B is in Group D?
Thanks.

Fetching size of object's list - Optional.get() without .ifPresent : <p>I have method that return <code>Optional</code> of Book object (do not mind with names as it is just a sample of code). I want to fetch the size of list which is inside Book class:</p>
<pre><code>public class Book {
Integer b;
DateTime dateOfCreation;
Integer a;
List<Integer> bookList;
}
</code></pre>
<p>So it goes like this: </p>
<pre><code>public class Main {
public static void main(String[] args) {
Optional<Book> book = getBookObject();
int sizeOfList = book.get().bookList.size();
}
static Optional<Book> getBookObject() {
return Optional.of(new Book());
}
}
</code></pre>
<p>I have warning within the <code>get()</code> which goes like <code>Optional.get() without .ifPresent</code> what is the proper approach to fetch this size of the list?</p>

How do you output a String, integer, and double from an array? : <p>I am trying to print out names with their associated information. I want their age, salary, insurance, etc. I am trying to use a for loop to accomplish this, but I'm obviously missing something. I also don't want it to total the ages, I want it individually. I just can't find a way to print all of my information.</p>
<pre><code>public static double printArray(int[] noclue, String[] name, double[] age, double[] salary, double[] insurance, double[] expense, double[] savings)
{
int total = 0;
String names = "";
for (int i = 0; i < noclue.length; i++)
{
total = total + noclue[i]
names = name[i];
}
return total;
return names;
}
}
</code></pre>
<p>In the main:</p>
<pre><code>System.out.println(array.printArray(noclue, name, age, salary,insurance, expenses, savings));

Change order of (sub-) strings in dataframe column based on white spaces : I have a dataframe with a column in python:
```
df
columnA
Apple Banana
Orange Citron Pineapple
```
How can I reserve the order of the substrings based on the white spaces? The outcome should be:
```
columnA
Banana Apple
Pineapple Citron Orange
```
Right now, I am only using:
```
df['columnA'] = df['columnA'].replace(r'(\s+).(\s+).(\s+)',r'\3\2\1',regex=True)
```
but this only works if I know the number of substrings, this I do not know upfront.

If input says x and y then print : Hi I'm trying to get this example code to work:

b = ("morning")
z = input("Hi: ")
z
if z == "hello":
print("good day!")
elif z == a and b:
print("Good Night")
else:
print("nope")
so I want it to print "Good Night" if the typed input is good morning (a and b) but it's not doing that, instead it's printing "nope", what's the mistake I'm doing?

docker version number confusion: 17.06 vs 1.13? : <p>I am confused by the version number of <code>docker</code></p>

<p>However, starting with Docker 17.06, you can also use <code>--mount</code> with standalone containers</p>

Is there a way to make .NET Core GetHashCode deterministic : <p>I just wasted few hours of debugging before realizing that contrary to .NET, in .NET Core, GetHashCode returns a different value every time you run your code.
I totally understand the rationale for this. Relying on hash code values is a very bad idea (like serializing them). I even remember that internal builds of .NET at Microsoft (prior to Core) would change the behavior of GetHashCode for every build so that nobody gets too comfortable with it.</p>
<p>Having said all this, I’m currently debugging complex code that makes heavy use of GetHashCode. I know the bug is my own doing and has nothing to do with GetHashCode but each time I run it, it fails elsewhere. Very annoying.
Is there a way to force GetHashCode to behave like in .NET (while I’m debugging) without having to write my own hash function and having to replace it everywhere in my code?</p>

How to test navigation via Navigator in Flutter : <p>Let's say, I have a test for a screen in Flutter using <code>WidgetTester</code>. There is a button, which executes a navigation via <code>Navigator</code>. I would like to test behavior of that button. </p>
<p><strong>Widget/Screen</strong></p>
<pre><code>class MyScreen extends StatefulWidget {
MyScreen({Key key}) : super(key: key);
@override
_MyScreenState createState() => _MyScreenScreenState();
}
class _MyScreenState extends State<MyScreen> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: RaisedButton(
onPressed: () {
Navigator.of(context).pushNamed("/nextscreen");
},
child: Text(Strings.traktTvUrl)
)
)
);
}
}
</code></pre>
<p><strong>Test</strong></p>
<pre><code>void main() {
testWidgets('Button is present and triggers navigation after tapped',
(WidgetTester tester) async {
await tester.pumpWidget(MaterialApp(home: MyScreen()));
expect(find.byType(RaisedButton), findsOneWidget);
await tester.tap(find.byType(RaisedButton));
//how to test navigator?
});
}
</code></pre>
<p>I there a proper way how to check, that Navigator was called? Or is there a way to mock and replace navigator?</p>
<p>Pleas note, that code above will actually fail with an exception, because there is no named route <code>'/nextscreen'</code> declared in application. That's simple to solve and you don't need to point it out.</p>
<p>My main concern is how to correctly approach this test scenario in Flutter.</p>

I tested:
$('#amount').change(function(){
var myamount = parseFloat($("#amount").text().replace(',', '.'));
if(myamount > 232.68){

<p>I understand that in C# <code>array.GetUpperBound(0)</code> would return <code>1</code> (the last index of the first dimension) and <code>array.GetUpperBound(1)</code> would return <code>2</code> (the last index of the second dimension).</p>
<p>How someone could implement this functionality in java? Is C#'s <code>array.GetUpperBound(0)</code> the same as Java's <code>array[0].length - 1</code> or <code>array.length - 1</code>?</p>
