I'm not sure why you "can't login to the Apple Developer Forums", but (without violating the NDA) you can also hide your statusBar through Xcode. It's a general setting on your application target.

I know this doesn't answer the question, but with Material Design (API 21+) we can change the color of the status bar by adding this line in the theme declaration in styles.xml:

<!-- MAIN THEME -->
<style name="AppTheme" parent="@android:style/Theme.Material.Light">
    <item name="android:actionBarStyle">@style/actionBarCustomization</item>
    <item name="android:spinnerDropDownItemStyle">@style/mySpinnerDropDownItemStyle</item>
    <item name="android:spinnerItemStyle">@style/mySpinnerItemStyle</item>
    <item name="android:colorButtonNormal">@color/myDarkBlue</item>
    <item name="android:statusBarColor">@color/black</item>
</style>

Notice the android:statusBarColor, where we can define the color, otherwise the default is used.

SOLUTION :

Set it in your viewcontroller or in rootviewcontroller by overriding the method :

-(BOOL) prefersStatusBarHidden
    {
        return YES;
    }

I've tried so many things.

Finally, It is the most suitable code to hide and show full screen mode.

private fun hideSystemUi() {

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        window.setDecorFitsSystemWindows(true)
    } else {
        // hide status bar
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        window.decorView.systemUiVisibility =
            View.SYSTEM_UI_FLAG_IMMERSIVE or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
    }

}

private fun showSystemUi() {

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        window.setDecorFitsSystemWindows(false)
    } else {
        // Show status bar
        window.clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        window.decorView.systemUiVisibility = SYSTEM_UI_FLAG_LAYOUT_STABLE
    }

}

It Implemented it in this app : Android Breakdown.

Go to Videos(Bottom Bar) > Play Any Video > Toggle Fullscreen

This worked for me:

1. Set the UIViewControllerBasedStatusBarAppearance to YES in the plist

2. The rootViewController needs the method implementation for

   -(UIStatusBarStyle)preferredStatusBarStyle
   

Because my rootViewController is managed by Cocoapods (JASidePanelController) I added this method through a category:

#import "JASidePanelController+StatusBarStyle.h"

@implementation JASidePanelController (StatusBarStyle)

- (UIStatusBarStyle)preferredStatusBarStyle
{
    return UIStatusBarStyleLightContent;
}

@end

Toggled Fullscreen Solution:

This solution may look like a workaround, but it actually accounts for whether your app is fullscreen (aka hiding the status bar) or not:

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point(); display.getSize(size);
int barheight = size.y - findViewById(R.id.rootView).getHeight();

This way, if your app is currently fullscreen, barheight will equal 0.

Personally I had to use this to correct absolute TouchEvent coordinates to account for the status bar as so:

@Override
public boolean onTouch(View view,MotionEvent event) {
    Display display = getWindowManager().getDefaultDisplay();
    Point size = new Point(); display.getSize(size);
    int YCoord = (int)event.getRawY() - size.y + rootView.getHeight());
}

And that will get the absolute y-coordinate whether the app be fullscreen or not.

Enjoy

I can suggest you a simpler way,

1. Just call setNeedsStatusBarAppearanceUpdate in viewDidLoad as Apple docs says,

Call this method if the view controller's status bar attributes, such as hidden/unhidden status or style, change. If you call this method within an animation block, the changes are animated along with the rest of the animation block.

2. Implement preferredStatusBarStyle returning your preferred type.

It worked for me in iOS 10.1.

Objective C

[self setNeedsStatusBarAppearanceUpdate];

-(UIStatusBarStyle)preferredStatusBarStyle {
     return UIStatusBarStyleLightContent;
}

Swift

setNeedsStatusBarAppearanceUpdate()

var preferredStatusBarStyle: UIStatusBarStyle { 
    return .lightContent
}

I am surprised nobody pointed this out. Anyway enjoy :)

Add the following to your Info.plist:

<key>UIStatusBarHidden</key>
<true/>
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>

I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics

If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.

UIBarPositionTopAttached

Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.

Add the following code to your view controller:

if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {
    // iOS 7
    [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
} else {
    // iOS 6
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
}

- (BOOL)prefersStatusBarHidden {
    return YES;
}

If you want "Use Autolayout" to be enabled at any cost place the following code in viewdidload.

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) 
{
        self.edgesForExtendedLayout = UIRectEdgeNone;
        self.extendedLayoutIncludesOpaqueBars = NO;
        self.automaticallyAdjustsScrollViewInsets = NO;
}

1. Add a key in your info.plist file UIViewControllerBasedStatusBarAppearance and set it to YES.

2. In viewDidLoad method of your ViewController add a method call:

   [self setNeedsStatusBarAppearanceUpdate];
   

3. Then paste the following method in viewController file:

   - (UIStatusBarStyle)preferredStatusBarStyle
   { 
       return UIStatusBarStyleLightContent; 
   }
   

Instead of using the ScrimInsetsFrameLayout... Isn't it easier to just add a view with a fixed height of 24dp and a background of primaryColor?

I understand that this involves adding a dummy view in the hierarchy, but it seems cleaner to me.

I already tried it and it's working well.

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

Use android:fitsSystemWindows="false" in your top layout

You can simply use back() function to redirect no need to use redirect()->back() make sure you are using 5.2 or greater than 5.2 version.

You can replace your code to below code.

return back()->with('message', 'WORKS!');

In the view file replace below code.

@if(session()->has('message'))
    <div class="alert alert-success">
        {{ session()->get('message') }}
    </div>
@endif

For more detail, you can read here

back() is just a helper function. It's doing the same thing as redirect()->back()

Here's a simpler version in python. It does use only two pointers slow & fast

def reverseList(head: ListNode) -> ListNode:

    slow = None
    fast = head
    while fast:  
        node_next = fast.next
        
        fast.next = slow
        slow = fast
            
        fast = node_next
    return slow

Now you can use ViewPager2 for dynamically adding, removing fragment from the viewpager.

Quoting form API reference

ViewPager2 replaces ViewPager, addressing most of its predecessor’s pain-points, including right-to-left layout support, vertical orientation, modifiable Fragment collections, etc.

Take look at MutableCollectionFragmentActivity.kt in googlesample/android-viewpager2 for an example of adding, removing fragments dynamically from the viewpager.

The previous answers are correct but remember to use the name attribute in the input fields (html form) or you won't get anything. Example:

<input type="text" id="username" /> <!-- won't work --> <input type="text" name="username" /> <!-- will work --> <input type="text" name="username" id="username" /> <!-- will work too -->

All this code is HTML valid, but using getParameter(java.lang.String) you will need the name attribute been set in all parameters you want to receive.

Neither "new" or "delete" should ever be used in application code. Instead, create a new type that uses the manager/worker idiom, in which the manager class allocates and frees memory and forwards all other operations to the worker object.

Unfortunately this is more work than it should be because C++ doesn't have overloading of "operator .". It is even more work in the presence of polymorphism.

But this is worth the effort because you then don't ever have to worry about memory leaks, which means you don't even have to look for them.

In Tomcat 6, the CLASSPATH in your environment is ignored. In setclasspath.bat you'll see

set CLASSPATH=%JAVA_HOME%\lib\tools.jar

then in catalina.bat, it's used like so

%_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% %DEBUG_OPTS% 
-Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%" 
-Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%" 
-Djava.io.tmpdir="%CATALINA_TMPDIR%" %MAINCLASS% %CMD_LINE_ARGS% %ACTION%

I don't see any other vars that are included, so I think you're stuck with editing setclasspath.bat and changing how CLASSPATH is built. For Tomcat 6.0.20, this change was on like 74 of setclasspath.bat

set CLASSPATH=C:\app_config\java_app;%JAVA_HOME%\lib\tools.jar

It can be done this way as well:

$('input', '#div').each(function () {
    console.log($(this)); //log every element found to console output
});

intersect_all <- function(a,b,...){
  all_data <- c(a,b,...)
  require(plyr)
  count_data<- length(list(a,b,...))
  freq_dist <- count(all_data)
  intersect_data <- freq_dist[which(freq_dist$freq==count_data),"x"]
  intersect_data
}


intersect_all(a,b,c)

UPDATE EDIT A simpler code

intersect_all <- function(a,b,...){
  Reduce(intersect, list(a,b,...))
}

intersect_all(a,b,c)

From a quick google search it seems that the problem is a file or url couldn't be found be the HTTPservice.

then schedule a task to run that MoveFiles.bat every 10 hours.

Python 3 ints do not have a maximum.

If your purpose is to determine the maximum size of an int in C when compiled the same way Python was, you can use the struct module to find out:

>>> import struct
>>> platform_c_maxint = 2 ** (struct.Struct('i').size * 8 - 1) - 1

If you are curious about the internal implementation details of Python 3 int objects, Look at sys.int_info for bits per digit and digit size details. No normal program should care about these.

In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic about following the C++ standard), you can do:

int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++

If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:

int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!

Or, better yet, use a standard container:

int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>

If you still want a proper array, you can use a constant, not a variable, when creating it:

const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)

Similarly, if you want to get the size from a function in C++11, you can use a constexpr:

constexpr int n()
{
    return 10;
}

double a[n()]; // n() is a compile time constant expression

// Captura datos usando metodo GET en la url colocar index.html?hola=chao
const $_GET = {};
const args = location.search.substr(1).split(/&/);
for (let i=0; i<args.length; ++i) {
    const tmp = args[i].split(/=/);
    if (tmp[0] != "") {
        $_GET[decodeURIComponent(tmp[0])] = decodeURIComponent(tmp.slice(1).join("").replace("+", " "));
        console.log(`>>${$_GET['hola']}`);
    }//::END if
}//::END for

It is clear from the error.

The HtmlHelpers appended with "For" expects lambda expression as a parameter.

If you are passing the value directly, better use Normal one.

e.g.

Instead of TextboxFor(....) use Textbox()

syntax for TextboxFor will be like Html.TextBoxFor(m=>m.Property)

In your scenario you can use basic for loop, as it will give you index to use.

@for(int i=0;i<Model.Theme.Count;i++)
 {
   @Html.LabelFor(m=>m.Theme[i].name)
   @for(int j=0;j<Model.Theme[i].Products.Count;j++) )
     {
      @Html.LabelFor(m=>m.Theme[i].Products[j].name)
      @for(int k=0;k<Model.Theme[i].Products[j].Orders.Count;k++)
          {
           @Html.TextBoxFor(m=>Model.Theme[i].Products[j].Orders[k].Quantity)
           @Html.TextAreaFor(m=>Model.Theme[i].Products[j].Orders[k].Note)
           @Html.EditorFor(m=>Model.Theme[i].Products[j].Orders[k].DateRequestedDeliveryFor)
      }
   }
}

On unix systems, you can use the following command to determine where git is installed:

If you are using MacOS and did a recent update, it is possible you have to agree to the licence terms again. Try typing 'git' in a terminal, and see if you get the following message:

In the old days, when we could assume that most computers used ASCII, we would just do

int i = c[0] - '0';

But in these days of Unicode, it's not a good idea. It was never a good idea if your code had to run on a non-ASCII computer.

Edit: Although it looks hackish, evidently it is guaranteed by the standard to work. Thanks @Earwicker.

I know my solution is not very popular from the pythonic point of view, but I prefer to use the Java approach of one module->one class, with the module named as the class. I do understand the reason behind the python style, but I am not too fond of having a very large file containing a lot of classes. I find it difficult to browse, despite folding.

Another reason is version control: having a large file means that your commits tend to concentrate on that file. This can potentially lead to a higher quantity of conflicts to be resolved. You also loose the additional log information that your commit modifies specific files (therefore involving specific classes). Instead you see a modification to the module file, with only the commit comment to understand what modification has been done.

Summing up, if you prefer the python philosophy, go for the suggestions of the other posts. If you instead prefer the java-like philosophy, create a Nib.py containing class Nib.

To improve the performance, you could use the Task Parallel Library (TPL). Here is a good sample: Directory file size calculation - how to make it faster?

I didn't test it, but the author says it is 3 times faster than a non-multithreaded method...

In your MoviesService you should import FirebaseListObservable in order to define return type FirebaseListObservable<any[]>

import { AngularFireDatabase, FirebaseListObservable } from 'angularfire2/database';

then get() method should like this-

get (): FirebaseListObservable<any[]>{
        return this.db.list('/movies');
    }

this get() method will return FirebaseListObervable of movies list

In your MoviesComponent should look like this

export class MoviesComponent implements OnInit {
  movies: any[];

  constructor(private moviesDb: MoviesService) { }

  ngOnInit() {
    this.moviesDb.get().subscribe((snaps) => {
       this.movies = snaps;
   });
 }
}

Then you can easily iterate through movies without async pipe as movies[] data is not observable type, your html should be this

ul
  li(*ngFor='let movie of movies')
    {{ movie.title }}

if you declear movies as a

movies: FirebaseListObservable<any[]>;

then you should simply call

movies: FirebaseListObservable<any[]>;
ngOnInit() {
    this.movies = this.moviesDb.get();
}

and your html should be this

ul
  li(*ngFor='let movie of movies | async')
    {{ movie.title }}

In an instance where you want to set a placeholder and not have a default value be selected, you can use this option.

      <select defaultValue={'DEFAULT'} >
        <option value="DEFAULT" disabled>Choose a salutation ...</option>
        <option value="1">Mr</option>
        <option value="2">Mrs</option>
        <option value="3">Ms</option>
        <option value="4">Miss</option>
        <option value="5">Dr</option>
      </select>

Here the user is forced to pick an option!

EDIT

If this is a controlled component

In this case unfortunately you will have to use both defaultValue and value violating React a bit. This is because react by semantics does not allow setting a disabled value as active.

 function TheSelectComponent(props){
     let currentValue = props.curentValue || "DEFAULT";
     return(
      <select value={currentValue} defaultValue={'DEFAULT'} onChange={props.onChange}>
        <option value="DEFAULT" disabled>Choose a salutation ...</option>
        <option value="1">Mr</option>
        <option value="2">Mrs</option>
        <option value="3">Ms</option>
        <option value="4">Miss</option>
        <option value="5">Dr</option>
      </select>
    )
}

If you want to analyze, repair and optimize all tables in all databases in your MySQL server, you can do this in one go from the command line. You will need root to do that though.

mysqlcheck -u root -p --auto-repair --optimize --all-databases

Once you run that, you will be prompted to enter your MySQL root password. After that, it will start and you will see results as it's happening.

Example output:

yourdbname1.yourdbtable1       OK
yourdbname2.yourdbtable2       Table is already up to date
yourdbname3.yourdbtable3
note     : Table does not support optimize, doing recreate + analyze instead
status   : OK

etc..
etc...

Repairing tables
yourdbname10.yourdbtable10
warning  : Number of rows changed from 121378 to 81562
status   : OK

If you don't know the root password and are using WHM, you can change it from within WHM by going to: Home > SQL Services > MySQL Root Password

As per my understanding data structure is any data residing in memory of any electronic system that can be efficiently managed. Many times it is a game of memory or faster accessibility of data. In terms of memory again, there are tradeoffs done with the management of data based on cost to the company of that end product. Efficiently managed tells us how best the data can be accessed based on the primary requirement of the end product. This is a very high level explanation but data structures is a vast subjects. Most of the interviewers dive into data structures that they can afford to discuss in the interviews depending on the time they have, which are linked lists and related subjects.

Now, these data types can be divided into primitive, abstract, composite, based on the way they are logically constructed and accessed.

• primitive data structures are basic building blocks for all data structures, they have a continuous memory for them: boolean, char, int, float, double, string.
• composite data structures are data structures that are composed of more than one primitive data types.class, structure, union, array/record.
• abstract datatypes are composite datatypes that have way to access them efficiently which is called as an algorithm. Depending on the way the data is accessed data structures are divided into linear and non linear datatypes. Linked lists, stacks, queues, etc are linear data types. heaps, binary trees and hash tables etc are non linear data types.

I hope this helps you dive in.

use fwrite() instead of file_put_contents()

The reason why you are getting the compilation error is, you are trying to access the session in declaration block (<%! %>) where it is not available. All the implicit objects of jsp are available in service method only. Code of declarative blocks goes outside the service method.

I'd advice you to use EL. It is a simplified approach.

${sessionScope.username} would give you the desired output.

From ScottGu's blog:

Starting with the ASP.NET MVC 3 Beta release, you can now add a file called _ViewStart.cshtml (or _ViewStart.vbhtml for VB) underneath the \Views folder of your project:

The _ViewStart file can be used to define common view code that you want to execute at the start of each View’s rendering. For example, we could write code within our _ViewStart.cshtml file to programmatically set the Layout property for each View to be the SiteLayout.cshtml file by default:

Because this code executes at the start of each View, we no longer need to explicitly set the Layout in any of our individual view files (except if we wanted to override the default value above).

Important: Because the _ViewStart.cshtml allows us to write code, we can optionally make our Layout selection logic richer than just a basic property set. For example: we could vary the Layout template that we use depending on what type of device is accessing the site – and have a phone or tablet optimized layout for those devices, and a desktop optimized layout for PCs/Laptops. Or if we were building a CMS system or common shared app that is used across multiple customers we could select different layouts to use depending on the customer (or their role) when accessing the site.

This enables a lot of UI flexibility. It also allows you to more easily write view logic once, and avoid repeating it in multiple places.

Also see this.

In a more general sense this ability of MVC framework to "know" about _Viewstart.cshtml is called "Coding by convention".

Convention over configuration (also known as coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility. The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called “sales” by default. It is only if one deviates from this convention, such as calling the table “products_sold”, that one needs to write code regarding these names.

Wikipedia

There's no magic to it. Its just been written into the core codebase of the MVC framework and is therefore something that MVC "knows" about. That why you don't find it in the .config files or elsewhere; it's actually in the MVC code. You can however override to alter or null out these conventions.

You could do:

if($('.input1').length && $('.input1').val().length)

length evaluates to false in a condition, when the value is 0.

For clarity, I'd like to illustrate @Joey's answer above with these gifs :

I personally was searching for something to let me compute the multiline string area, so I could determine if given area is big enough to print the string - with preserving specific font.

private static Hashtable hash = new Hashtable();
private Font font;
private LineBreakMeasurer lineBreakMeasurer;
private int start, end;

public PixelLengthCheck(Font font) {
    this.font = font;
}

public boolean tryIfStringFits(String textToMeasure, Dimension areaToFit) {
    AttributedString attributedString = new AttributedString(textToMeasure, hash);
    attributedString.addAttribute(TextAttribute.FONT, font);
    AttributedCharacterIterator attributedCharacterIterator =
            attributedString.getIterator();
    start = attributedCharacterIterator.getBeginIndex();
    end = attributedCharacterIterator.getEndIndex();

    lineBreakMeasurer = new LineBreakMeasurer(attributedCharacterIterator,
            new FontRenderContext(null, false, false));

    float width = (float) areaToFit.width;
    float height = 0;
    lineBreakMeasurer.setPosition(start);

    while (lineBreakMeasurer.getPosition() < end) {
        TextLayout textLayout = lineBreakMeasurer.nextLayout(width);
        height += textLayout.getAscent();
        height += textLayout.getDescent() + textLayout.getLeading();
    }

    boolean res = height <= areaToFit.getHeight();

    return res;
}

The projects you are trying to open are in the new .NET Core csproj format. This means you need to use Visual Studio 2017 which supports this new format.

For a little bit of history, initially .NET Core used project.json instead of *.csproj. However, after some considerable internal deliberation at Microsoft, they decided to go back to csproj but with a much cleaner and updated format. However, this new format is only supported in VS2017.

If you want to open the projects but don't want to wait until March 7^th for the official VS2017 release, you could use Visual Studio Code instead.

In the Object Explorer, drill-down to: Server -> Management -> Activity Monitor. This will allow you to see all connections on to the current server.

With kotlin this is the way I did:

class LoginActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_login)
        window.decorView.systemUiVisibility =
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE or

Immersive Mode

The immersive mode is intended for apps in which the user will be heavily interacting with the screen. Examples are games, viewing images in a gallery, or reading paginated content, like a book or slides in a presentation. For this, just add this lines:

View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION

Sticky immersive

In the regular immersive mode, any time a user swipes from an edge, the system takes care of revealing the system bars—your app won't even be aware that the gesture occurred. So if the user might actually need to swipe from the edge of the screen as part of the primary app experience—such as when playing a game that requires lots of swiping or using a drawing app—you should instead enable the "sticky" immersive mode.

View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY

In case your using the keyboard, sometimes happens that StatusBar shows when keyboard shows up. In that case I usually add this to my style xml

styles.xml

<style name="FullScreen" parent="AppTheme">
    <item name="android:windowFullscreen">true</item>
</style>

And also this line to my manifest

<activity
        android:name=".ui.login.LoginActivity"
        android:label="@string/title_activity_login"
        android:theme="@style/FullScreen">

I did not manage to make the most popular answers work.

• The ee method complained when my replacement string contained several consecutive backreferences.
• Kent Fredric's answer only replaced the first match, and I need my search and replace to be global. I did not figure out a way to make it replace all matches that didn't cause other issues. For example, I tried running the method recursively until it no longer caused the string to change, but that causes an infinite loop if the replacement string contains the search string, whereas a regular global replacement does not do that.

I attempted to come up with a solution of my own using plain old eval:

eval '$var =~ s/' . $find . '/' . $replace . '/gsu;';

Of course, this allows for code injection. But as far as I know, the only way to escape the regex query and inject code is to insert two forward slashes in $find or one in $replace, followed by a semi-colon, after which you can add add code. For example, if I set the variables this way:

my $find = 'foo';
my $replace = 'bar/; print "You\'ve just been hacked!\n"; #';

The evaluated code is this:

$var =~ s/foo/bar/; print "You've just been hacked!\n"; #/gsu;';

So what I do is make sure the strings don't contain any unescaped forward slashes.

First, I copy the strings into dummy strings.

my $findTest = $find;
my $replaceTest = $replace;

Then, I remove all escaped backslashes (backslash pairs) from the dummy strings. This allows me to find forward slashes that are not escaped, without falling into the trap of considering a forward slash escaped if it's preceded by an escaped backslash. For example: \/ contains an escaped forward slash, but \\/ contains a literal forward slash, because the backslash is escaped.

$findTest =~ s/\\\\//gmu;
$replaceTest =~ s/\\\\//gmu;

Now if any forward slash that is not preceded by a backslash remains in the strings, I throw a fatal error, as that would allow the user to insert arbitrary code.

if ($findTest =~ /(?<!\\)\// || $replaceTest =~ /(?<!\\)\//)
{
  print "String must not contain unescaped slashes.\n";
  exit 1;
}

Then I eval.

eval '$var =~ s/' . $find . '/' . $replace . '/gsu;';

I'm not an expert at preventing code injection, but I'm the only one using my script, so I'm content using this solution without fully knowing if it's vulnerable. But as far as I know, it may be, so if anyone knows if there is or isn't any way to inject code into this, please provide your insight in a comment.

I'm surprised no one offered this answer. It's not as "built-in" as Ruby's ||= but it's basically equivalent and still a one-liner:

foo = foo if 'foo' in locals() else 'default'

Of course, locals() is just a dictionary, so you can do:

foo = locals().get('foo', 'default')

I found a tricky solution... which works only in a RelativeLayout. We only need to put a View above a ListView and set clickable 'true' on View and false for the ListView

 <ListView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/listview
    android:clickable="false" />

<View
    android:layout_width="match_parent"
    android:background="@drawable/gradient_white"
    android:layout_height="match_parent"
    android:clickable="true"
    android:layout_centerHorizontal="true"
    android:layout_alignTop="@+id/listview" />

In general, i.e. unlimited decimal places:

^-?(([1-9]\d*)|0)(.0*[1-9](0*[1-9])*)?$

u = urllib2.urlopen('http://myserver/inout-tracker', data)
h.request('POST', '/inout-tracker/index.php', data, headers)

Using the path /inout-tracker without a trailing / doesn't fetch index.php. Instead the server will issue a 302 redirect to the version with the trailing /.

Doing a 302 will typically cause clients to convert a POST to a GET request.

Best step to resolve this error is- Uncheck the instant run in File >Settings >Build,Execution,Deployment > Instant Run

If you just want a straightforward non-weighted moving average, you can easily implement it with np.cumsum, which may be is faster than FFT based methods:

EDIT Corrected an off-by-one wrong indexing spotted by Bean in the code. EDIT

def moving_average(a, n=3) :
    ret = np.cumsum(a, dtype=float)
    ret[n:] = ret[n:] - ret[:-n]
    return ret[n - 1:] / n

>>> a = np.arange(20)
>>> moving_average(a)
array([  1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.,  11.,
        12.,  13.,  14.,  15.,  16.,  17.,  18.])
>>> moving_average(a, n=4)
array([  1.5,   2.5,   3.5,   4.5,   5.5,   6.5,   7.5,   8.5,   9.5,
        10.5,  11.5,  12.5,  13.5,  14.5,  15.5,  16.5,  17.5])

So I guess the answer is: it is really easy to implement, and maybe numpy is already a little bloated with specialized functionality.

I have to make an application which shows the Contact no of the SIM card that is being used in the cell. For that I need to use Telephony Manager class. Can i get details on its usage?

Yes, You have to use Telephony Manager;If at all you not found the contact no. of user; You can get Sim Serial Number of Sim Card and Imei No. of Android Device by using the same Telephony Manager Class...

Add permission:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Import:

import android.telephony.TelephonyManager;

Use the below code:

TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

         // get IMEI
         imei = tm.getDeviceId();

         // get SimSerialNumber
         simSerialNumber = tm.getSimSerialNumber();

Use the bootstrap classes to your advantage. navbar-static-bottom leaves it at the bottom.

<div class="navbar-static-bottom" id="footer"></div>

The relationship between automatically generated sequences ( such as those created for SERIAL columns ) and the parent table is modelled by the sequence owner attribute.

You can modify this relationship using the OWNED BY clause of the ALTER SEQUENCE commmand

e.g. ALTER SEQUENCE foo_id OWNED by foo_schema.foo_table

to set it to be linked to the table foo_table

or ALTER SEQUENCE foo_id OWNED by NONE

to break the connection between the sequence and any table

The information about this relationship is stored in the pg_depend catalogue table.

the joining relationship is the link between pg_depend.objid -> pg_class.oid WHERE relkind = 'S' - which links the sequence to the join record and then pg_depend.refobjid -> pg_class.oid WHERE relkind = 'r' , which links the join record to the owning relation ( table )

This query returns all the sequence -> table dependencies in a database. The where clause filters it to only include auto generated relationships, which restricts it to only display sequences created by SERIAL typed columns.

WITH fq_objects AS (SELECT c.oid,n.nspname || '.' ||c.relname AS fqname , 
                           c.relkind, c.relname AS relation 
                    FROM pg_class c JOIN pg_namespace n ON n.oid = c.relnamespace ),

     sequences AS (SELECT oid,fqname FROM fq_objects WHERE relkind = 'S'),  
     tables    AS (SELECT oid, fqname FROM fq_objects WHERE relkind = 'r' )  
SELECT
       s.fqname AS sequence, 
       '->' as depends, 
       t.fqname AS table 
FROM 
     pg_depend d JOIN sequences s ON s.oid = d.objid  
                 JOIN tables t ON t.oid = d.refobjid  
WHERE 
     d.deptype = 'a' ;

I would suggest you have a look at the Spring Cloud Netflix Hystrix starter to handle potentially unreliable/slow remote calls. It implements the Circuit Breaker pattern, that is intended for precisely this sorta thing.

See offcial docs for more information.

If using Node version >= 4, use Object.assign() (see Ricardo Nolde's answer).

If using Node 0.x, there is the built in util._extend:

var extend = require('util')._extend
var o = extend({}, {name: "John"});
extend(o,  {location: "San Jose"});

It doesn't do a deep copy and only allows two arguments at a time, but is built in. I saw this mentioned on a question about cloning objects in node: https://stackoverflow.com/a/15040626.

If you're concerned about using a "private" method, you could always proxy it:

// myutil.js
exports.extend = require('util')._extend;

and replace it with your own implementation if it ever disappears. This is (approximately) their implementation:

exports.extend = function(origin, add) {
    if (!add || (typeof add !== 'object' && add !== null)){
        return origin;
    }

    var keys = Object.keys(add);
    var i = keys.length;
    while(i--){
        origin[keys[i]] = add[keys[i]];
    }
    return origin;
};

Its a little bit not sophisticated but this should work, for example lets say you want to cap your uilabel to 120x120, with max font size of 28:

magicLabel.numberOfLines = 0;
magicLabel.lineBreakMode = NSLineBreakByWordWrapping;
...
magicLabel.text = text;
    for (int i = 28; i>3; i--) {
        CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:(CGFloat)i] constrainedToSize:CGSizeMake(120.0f, CGFLOAT_MAX) lineBreakMode:NSLineBreakByWordWrapping];
        if (size.height < 120) {
            magicLabel.font = [UIFont systemFontOfSize:(CGFloat)i];
            break;
        }
    }

Just copy the .dll files to C:\windows\system32\

Threading is another possible solution. Although the Celery based solution is better for applications at scale, if you are not expecting too much traffic on the endpoint in question, threading is a viable alternative.

This solution is based on Miguel Grinberg's PyCon 2016 Flask at Scale presentation, specifically slide 41 in his slide deck. His code is also available on github for those interested in the original source.

From a user perspective the code works as follows:

1. You make a call to the endpoint that performs the long running task.
2. This endpoint returns 202 Accepted with a link to check on the task status.
3. Calls to the status link returns 202 while the taks is still running, and returns 200 (and the result) when the task is complete.

To convert an api call to a background task, simply add the @async_api decorator.

Here is a fully contained example:

from flask import Flask, g, abort, current_app, request, url_for
from werkzeug.exceptions import HTTPException, InternalServerError
from flask_restful import Resource, Api

    def clean_old_tasks():

        """
        global tasks
        while True:
            # Only keep tasks that are running or that finished less than 5
            # minutes ago.
            five_min_ago = datetime.timestamp(datetime.utcnow()) - 5 * 60
            tasks = {task_id: task for task_id, task in tasks.items()
                     if 'completion_timestamp' not in task or task['completion_timestamp'] > five_min_ago}

You should have access to the POST dictionary on the request object.

you may also want to look at

var hours = (datevalue1 - datevalue2).TotalHours;

As of Socket.IO 1.0 (May 2014), all connections begin with an HTTP polling request (more info here). That means that in addition to forwarding WebSocket traffic, you need to forward any transport=polling HTTP requests.

The solution below should redirect all socket traffic correctly, without redirecting any other traffic.

1. Enable the following Apache2 mods:

   sudo a2enmod proxy rewrite proxy_http proxy_wstunnel
   

2. Use these settings in your *.conf file (e.g. /etc/apache2/sites-available/mysite.com.conf). I've included comments to explain each piece:

   <VirtualHost *:80>
       ServerName www.mydomain.com
   
       # Enable the rewrite engine
       # Requires: sudo a2enmod proxy rewrite proxy_http proxy_wstunnel
       # In the rules/conds, [NC] means case-insensitve, [P] means proxy
       RewriteEngine On
   
       # socket.io 1.0+ starts all connections with an HTTP polling request
       RewriteCond %{QUERY_STRING} transport=polling       [NC]
       RewriteRule /(.*)           http://localhost:3001/$1 [P]
   
       # When socket.io wants to initiate a WebSocket connection, it sends an
       # "upgrade: websocket" request that should be transferred to ws://
       RewriteCond %{HTTP:Upgrade} websocket               [NC]
       RewriteRule /(.*)           ws://localhost:3001/$1  [P]
   
       # OPTIONAL: Route all HTTP traffic at /node to port 3001
       ProxyRequests Off
       ProxyPass           /node   http://localhost:3001
       ProxyPassReverse    /node   http://localhost:3001
   </VirtualHost>
   

3. I've included an extra section for routing /node traffic that I find handy, see here for more info.

You can set timeout like this,

con.setConnectTimeout(connectTimeout);
con.setReadTimeout(socketTimeout);

Create a role add this role to users, and then you can grant execute to all the routines in one shot to this role.

CREATE ROLE <abc>
GRANT EXECUTE TO <abc>

EDIT
This works in SQL Server 2005, I'm not sure about backward compatibility of this feature, I'm sure anything later than 2005 should be fine.

Well if you are getting into a linux machine you can use the package manager of that linux distro.

If you are using Ubuntu just use apt-get search python, check the list and do apt-get install python2.7 (not sure if python2.7 or python-2.7, check the list)

You could use yum in fedora and do the same.

if you want to install it on your windows machine i dont know any package manager, i would download the wget for windows, donwload the package from python.org and install it

Seems like the a tag is hidden. Remember Selenium is not able to interact with hidden element. Javascript is the only option in that case.

By css = By.cssSelector("a[href='/docs/configuration']");
WebElement element = driver.findElement(css);
((JavascriptExecutor)driver).executeScript("arguments[0].click();" , element);

Adding;

display: inline-block;

to the child elements will prevent them being split between columns.

SSLHandshakeException can be resolved 2 ways.

1. Incorporating SSL

   • Get the SSL (by asking the source system administrator, can also be downloaded by openssl command, or any browsers downloads the certificates)

   • Add the certificate into truststore (cacerts) located at JRE/lib/security

   • provide the truststore location in vm arguments as "-Djavax.net.ssl.trustStore="

2. Ignoring SSL

   For this #2, please visit my other answer on another stackoverflow website: How to ingore SSL verification Ignore SSL Certificate Errors with Java

I've came up with a "responsive" solution for fullscreen modals:

Fullscreen Modals that can be enabled only on certain breakpoints. In this way the modal will display "normal" on wider (desktop) screens and fullscreen on smaller (tablet or mobile) screens, giving it the feeling of a native app.

Implemented for Bootstrap 3 and Bootstrap 4. Included by default in Bootstrap 5.

Bootstrap v5

Fullscreen modals are included by default in Bootstrap 5: https://getbootstrap.com/docs/5.0/components/modal/#fullscreen-modal

Bootstrap v4

The following generic code should work:

.modal {
  padding: 0 !important; // override inline padding-right added from js
}
.modal .modal-dialog {
  width: 100%;
  max-width: none;
  height: 100%;
  margin: 0;
}
.modal .modal-content {
  height: 100%;
  border: 0;
  border-radius: 0;
}
.modal .modal-body {
  overflow-y: auto;
}

By including the scss code below, it generates the following classes that need to be added to the .modal element:

+---------------+---------+---------+---------+---------+---------+
|               |   xs    |   sm    |   md    |   lg    |   xl    | 
|               | <576px  | =576px  | =768px  | =992px  | =1200px |
+---------------+---------+---------+---------+---------+---------+
|.fullscreen    |  100%   | default | default | default | default | 
+---------------+---------+---------+---------+---------+---------+
|.fullscreen-sm |  100%   |  100%   | default | default | default | 
+---------------+---------+---------+---------+---------+---------+
|.fullscreen-md |  100%   |  100%   |  100%   | default | default |
+---------------+---------+---------+---------+---------+---------+
|.fullscreen-lg |  100%   |  100%   |  100%   |  100%   | default |
+---------------+---------+---------+---------+---------+---------+
|.fullscreen-xl |  100%   |  100%   |  100%   |  100%   |  100%   |
+---------------+---------+---------+---------+---------+---------+

The scss code is:

@mixin modal-fullscreen() {
  padding: 0 !important; // override inline padding-right added from js

  .modal-dialog {
    width: 100%;
    max-width: none;
    height: 100%;
    margin: 0;
  }

  .modal-content {
    height: 100%;
    border: 0;
    border-radius: 0;
  }

  .modal-body {
    overflow-y: auto;
  }

}

@each $breakpoint in map-keys($grid-breakpoints) {
  @include media-breakpoint-down($breakpoint) {
    $infix: breakpoint-infix($breakpoint, $grid-breakpoints);

    .modal-fullscreen#{$infix} {
      @include modal-fullscreen();
    }
  }
}

Demo on Codepen: https://codepen.io/andreivictor/full/MWYNPBV/

Bootstrap v3

Based on previous responses to this topic (@Chris J, @kkarli), the following generic code should work:

.modal {
  padding: 0 !important; // override inline padding-right added from js
}

.modal .modal-dialog {
  width: 100%;
  height: 100%;
  margin: 0;
  padding: 0;
}

.modal .modal-content {
  height: auto;
  min-height: 100%;
  border: 0 none;
  border-radius: 0;
  box-shadow: none;
}

If you want to use responsive fullscreen modals, use the following classes that need to be added to .modal element:

• .modal-fullscreen-md-down - the modal is fullscreen for screens smaller than 1200px.
• .modal-fullscreen-sm-down - the modal is fullscreen for screens smaller than 922px.
• .modal-fullscreen-xs-down - the modal is fullscreen for screen smaller than 768px.

Take a look at the following code:

/* Extra small devices (less than 768px) */
@media (max-width: 767px) {
  .modal-fullscreen-xs-down {
    padding: 0 !important;
  }
  .modal-fullscreen-xs-down .modal-dialog {
    width: 100%;
    height: 100%;
    margin: 0;
    padding: 0;
  }
  .modal-fullscreen-xs-down .modal-content {
    height: auto;
    min-height: 100%;
    border: 0 none;
    border-radius: 0;
    box-shadow: none;
  } 
}

/* Small devices (less than 992px) */
@media (max-width: 991px) {
  .modal-fullscreen-sm-down {
    padding: 0 !important;
  }
  .modal-fullscreen-sm-down .modal-dialog {
    width: 100%;
    height: 100%;
    margin: 0;
    padding: 0;
  }
  .modal-fullscreen-sm-down .modal-content {
    height: auto;
    min-height: 100%;
    border: 0 none;
    border-radius: 0;
    box-shadow: none;

  .modal-dialog {
    width: 100%;
    height: 100%;
    margin: 0;

In Chrome (Canary) I unchecked "Appspector" extension. That cleared the error.

Assuming your page is available under "http://example.com"

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://example.com")

Select element by id:

inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')

Now you can simulate hitting ENTER:

inputElement.send_keys(Keys.ENTER)

or if it is a form you can submit:

inputElement.submit() 

Pure Virtual Functions are mostly used to define:

a) abstract classes

These are base classes where you have to derive from them and then implement the pure virtual functions.

b) interfaces

These are 'empty' classes where all functions are pure virtual and hence you have to derive and then implement all of the functions.

Pure virtual functions are actually functions which have no implementation in base class and have to be implemented in derived class.

I think this is what you want...

Not quite as elegant as some of the functionality on Unix, but create a cmd file which looks like:

@echo off
time < nul
yourexecutable.exe > c:\temp\output.txt
time < nul
rem on newer windows system you can try time /T

That will display the start and stop times like so:

The current time is: 10:31:57.92
Enter the new time:
The current time is: 10:32:05.94
Enter the new time:

int i = 7122960;
decimal d = (decimal)i / 100;

We can select required fields over values.

In my Case Problem solved with Instant Run Disable in Android Studio 3.1.2

I solved this by clearing all the plots in the console and then making sure the plot area was large enough to accommodate what I was creating.

I had same problem with a site on our direct admin hosted site. I added

DirectoryIndex index.php

as a custom httd extension (which adds code to a sites httpd file) and the site then ran the index.php by default.

I had two problems with using Acrobat Reader for this task.

1. The command line API is not officially supported, so it could change or be removed without warning.
2. Send a print command to Reader loads up the GUI, with seemingly no way to prevent it. I needed the process to be transparent to the user.

I stumbled across this blog, that suggests using Foxit Reader. Foxit Reader is free, the API is almost identical to Acrobat Reader, but crucially is documented and does not load the GUI for print jobs.

A word of warning, don't just click through the install process without paying attention, it tries to install unrelated software as well. Why are software vendors still doing this???

I know this posting is old, but I had the same problem, WAMP would not go online (green) while SKYPE was running. I simply closed SKYPE, ran WAMP and then reloaded SKYPE. I have not verified this, but I think SKYPE port corrected to allow for WAMP settings. At least I have not experienced any problems doing it this way

From Ubuntu 18.4 (Bionic Beaver) it is advisable to use apt instead of apt-get since it has much better structural form.

sudo apt install libxml2-dev libxslt1-dev python-dev

If you're happy with a possibly older version of lxml altogether though, you could try

sudo apt install python-lxml

Here an approach to have count distinct over multiple columns. Let's have some data:

data = {'CLIENT_CODE':[1,1,2,1,2,2,3],
        'YEAR_MONTH':[201301,201301,201301,201302,201302,201302,201302],
        'PRODUCT_CODE': [100,150,220,400,50,80,100]
       }
table = pd.DataFrame(data)
table

CLIENT_CODE YEAR_MONTH  PRODUCT_CODE
0   1       201301      100
1   1       201301      150
2   2       201301      220
3   1       201302      400
4   2       201302      50
5   2       201302      80
6   3       201302      100

Now, list the columns of interest and use groupby in a slightly modified syntax:

columns = ['YEAR_MONTH', 'PRODUCT_CODE']
table[columns].groupby(table['CLIENT_CODE']).nunique()

We obtain:

YEAR_MONTH  PRODUCT_CODE CLIENT_CODE        
1           2            3
2           2            3
3           1            1

Note: Git 1.8.2 added the possibility to track branches. See some of the answers below.

It's a little confusing to get used to this, but submodules are not on a branch. They are, like you say, just a pointer to a particular commit of the submodule's repository.

This means, when someone else checks out your repository, or pulls your code, and does git submodule update, the submodule is checked out to that particular commit.

This is great for a submodule that does not change often, because then everyone on the project can have the submodule at the same commit.

If you want to move the submodule to a particular tag:

cd submodule_directory
git checkout v1.0
cd ..
git add submodule_directory
git commit -m "moved submodule to v1.0"
git push

Then, another developer who wants to have submodule_directory changed to that tag, does this

git pull
git submodule update --init

git pull changes which commit their submodule directory points to. git submodule update actually merges in the new code.

There are many answers here already, but some have heavy upvotes and are incorrect.

The .NET Environment.ProcessorCount WILL return incorrect values and can fail critically if your system WMI is configured incorrectly.

If you want a RELIABLE way to count the cores, the only way is Win32 API.

Here is a C++ snippet:

#include <Windows.h>
#include <vector>

int num_physical_cores()
{
    static int num_cores = []
    {
        DWORD bytes = 0;
        GetLogicalProcessorInformation(nullptr, &bytes);
        std::vector<SYSTEM_LOGICAL_PROCESSOR_INFORMATION> coreInfo(bytes / sizeof(SYSTEM_LOGICAL_PROCESSOR_INFORMATION));
        GetLogicalProcessorInformation(coreInfo.data(), &bytes);

        int cores = 0;
        for (auto& info : coreInfo)
        {
            if (info.Relationship == RelationProcessorCore)
                ++cores;
        }
        return cores > 0 ? cores : 1;
    }();
    return num_cores;
}

And since this is a .NET C# Question, here's the ported version:

[StructLayout(LayoutKind.Sequential)]
struct CACHE_DESCRIPTOR
{
    public byte Level;
    public byte Associativity;
    public ushort LineSize;

    int numEntries = bufferSize / sizeof(SYSTEM_LOGICAL_PROCESSOR_INFORMATION);
    var coreInfo = new SYSTEM_LOGICAL_PROCESSOR_INFORMATION[numEntries];

    fixed (SYSTEM_LOGICAL_PROCESSOR_INFORMATION* pCoreInfo = coreInfo)
    {
        GetLogicalProcessorInformation(pCoreInfo, out bufferSize);
        int cores = 0;
        for (int i = 0; i < numEntries; ++i)
        {
            ref SYSTEM_LOGICAL_PROCESSOR_INFORMATION info = ref pCoreInfo[i];
            if (info.Relationship == LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorCore)
                ++cores;
        }
        return cores > 0 ? cores : 1;
    }
}

public static readonly int NumPhysicalCores = GetProcessorCoreCount();

The difference between <pluginManagement/> and <plugins/> is that a <plugin/> under:

• <pluginManagement/> defines the settings for plugins that will be inherited by modules in your build. This is great for cases where you have a parent pom file.

• <plugins/> is a section for the actual invocation of the plugins. It may or may not be inherited from a <pluginManagement/>.

You don't need to have a <pluginManagement/> in your project, if it's not a parent POM. However, if it's a parent pom, then in the child's pom, you need to have a declaration like:

<plugins>
    <plugin>
        <groupId>com.foo</groupId>
        <artifactId>bar-plugin</artifactId>
    </plugin>
</plugins>

Notice how you aren't defining any configuration. You can inherit it from the parent, unless you need to further adjust your invocation as per the child project's needs.

For more specific information, you can check:

• The Maven pom.xml reference: Plugins

• The Maven pom.xml reference: Plugin Management

Use fmod() from <cmath>. If you do not want to include the C header file:

template<typename T, typename U>
constexpr double dmod (T x, U mod)
{
    return !mod ? x : x - mod * static_cast<long long>(x / mod);
}

//Usage:
double z = dmod<double, unsigned int>(14.3, 4);
double z = dmod<long, float>(14, 4.6);
//This also works:
double z = dmod(14.7, 0.3);
double z = dmod(14.7, 0);
double z = dmod(0, 0.3f);
double z = dmod(myFirstVariable, someOtherVariable);

From Auth0.com

Token-Based Authentication, relies on a signed token that is sent to the server on each request.

What are the benefits of using a token-based approach?

• Cross-domain / CORS: cookies + CORS don't play well across different domains. A token-based approach allows you to make AJAX calls to any server, on any domain because you use an HTTP header to transmit the user information.

• Stateless (a.k.a. Server side scalability): there is no need to keep a session store, the token is a self-contained entity that conveys all the user information. The rest of the state lives in cookies or local storage on the client side.

• CDN: you can serve all the assets of your app from a CDN (e.g. javascript, HTML, images, etc.), and your server side is just the API.

• Decoupling: you are not tied to any particular authentication scheme. The token might be generated anywhere, hence your API can be called from anywhere with a single way of authenticating those calls.

• Mobile ready: when you start working on a native platform (iOS, Android, Windows 8, etc.) cookies are not ideal when consuming a token-based approach simplifies this a lot.

• CSRF: since you are not relying on cookies, you don't need to protect against cross site requests (e.g. it would not be possible to sib your site, generate a POST request and re-use the existing authentication cookie because there will be none).

• Performance: we are not presenting any hard perf benchmarks here, but a network roundtrip (e.g. finding a session on database) is likely to take more time than calculating an HMACSHA256 to validate a token and parsing its contents.

I figured I would post an updated answer for those looking at for something a little more current.

Currently Android and Android Studio are supporting a subset of Java 8 features. According to the Android documentation located on their website, Google says:

Support for Java 8 language features requires a new compiler called Jack. Jack is supported only on Android Studio 2.1 and higher. So if you want to use Java 8 language features, you need to use Android Studio 2.1 to build your app.

If you already have Android Studio installed, make sure you update to the latest version by clicking Help > Check for Update (on Mac, Android Studio > Check for Updates). If you don't already have the IDE installed on your workstation, download Android Studio here.

Supported Java 8 Language Features and APIs

Android does not support all Java 8 language features. However, the following features are available when developing apps targeting Android 7.0 (API level 24):

• Default and static interface methods Lambda expressions (also available on API level 23 and lower)
• Repeatable annotations
• Method References (also available on API level 23 and lower)
• Type Annotations (also available on API level 23 and lower)

Additionally, the following Java 8 language APIs are also available:

Reflection and language-related APIs:

• java.lang.FunctionalInterface
• java.lang.annotation.Repeatable
• java.lang.reflect.Method.isDefault() and Reflection APIs associated with repeatable annotations, such as AnnotatedElement.getAnnotationsByType(Class)

Utility APIs:

• java.util.function
• java.util.stream

In order to use the new Java 8 language features, you need to also use the Jack toolchain. This new Android toolchain compiles Java language sources into Android-readable DEX bytecode, has its own .jack library format, and provides most toolchain features as part of a single tool: repackaging, shrinking, obfuscation and multidex.

Here is a comparison of the two toolchains used to build Android DEX files:

Legacy javac toolchain:
    javac (.java ? .class) ? dx (.class ? .dex)
    New Jack toolchain:
    Jack (.java ? .jack ? .dex)

If you are using jQuery, there is a redirect plugin that works with the POST or GET method. It creates a form with hidden inputs and submits it for you. An example of how to get it working:

$.redirect('demo.php', {'arg1': 'value1', 'arg2': 'value2'});

Note: You can pass the method types GET or POST as an optional third parameter; POST is the default.

I'm guessing that you're trying to find if a certain value exists inside the array, and if that's the case, you can use Array#include?(value):

a = [1,2,3,4,5]
a.include?(3)   # => true
a.include?(9)   # => false

If you mean something else, check the Ruby Array API

HISTTIMEFORMAT="%d/%m/%y %H:%M "

For any commands typed prior to this, it will not help since they will just get a default time of when you turned history on, but it will log the time of any further commands after this.

If you want it to log history for permanent, you should put the following line in your ~/.bashrc

export HISTTIMEFORMAT="%d/%m/%y %H:%M "

Put this at the end of your app module build.gradle:

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '25.3.0'
            }
        }
    }
}

To highlight and beautify it in HTML using Bootstrap:

function prettifyJson(json, prettify) {
    if (typeof json !== 'string') {
        if (prettify) {
            json = JSON.stringify(json, undefined, 4);
        } else {
            json = JSON.stringify(json);
        }
    }
    return json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g,
        function(match) {
            let cls = "<span>";
            if (/^"/.test(match)) {
                if (/:$/.test(match)) {
                    cls = "<span class='text-danger'>";
                } else {
                    cls = "<span>";
                }
            } else if (/true|false/.test(match)) {
                cls = "<span class='text-primary'>";
            } else if (/null/.test(match)) {
                cls = "<span class='text-info'>";
            }
            return cls + match + "</span>";
        }
    );
}

If you're going for simple, you can avoid the "new" keyword entirely and just use factory methods. I prefer this, sometimes, because I like using JSON to create objects.

function getSomeObj(var1, var2){
  var obj = {
     instancevar1: var1,
     instancevar2: var2,
     someMethod: function(param)
     {  
          //stuff; 
     }
  };
  return obj;
}

var myobj = getSomeObj("var1", "var2");
myobj.someMethod("bla");

I'm not sure what the performance hit is for large objects, though.

We can use setTimeout function in such cases.

console.log('primary task');

setTimeout(function() {
  
  console.log('secondary task');

}, 0);

This will make sure that secondary task will be executed when execution of primary task is finished.

e.g.

 ColorTranslator.ToHtml(Color.FromArgb(Color.Tomato.ToArgb()))

This can avoid the KnownColor trick.

Do you have Excel installed on the server? The interop interfaces you're using are used to automate Excel which requires that the Excel application is installed there. Each page request cycle will potentially launch a separate instance of excel.exe. I would strongly advise against doing this as part of a web application.

Why do you want to do this? If you are wanting to generate Excel documents, there are much better ways to do this, including OpenXML as mentioned elsewhere on this thread. Please do not run Excel on the server!

Simple Option

Most methods for storing a dictionary use JSON, Pickle, or line reading. Providing you're not editing the dictionary outside of Python, this simple method should suffice for even complex dictionaries. Although Pickle will be better for larger dictionaries.

x = {1:'a', 2:'b', 3:'c'}
f = 'file.txt'
print(x, file=open(f,'w'))    # file.txt >>> {1:'a', 2:'b', 3:'c'}
y = eval(open(f,'r').read())
print(x==y)                   # >>> True

FWIW, @SergeyL's answer is great, but here is a slight variant for testing. Note the change in logical or to logical and.

main.c has a main wrapper like this:

#if !defined(TEST_SPI) && !defined(TEST_SERIAL) && !defined(TEST_USB)
int main(int argc, char *argv[]) {
  // the true main() routine.
}

spi.c, serial.c and usb.c have main wrappers for their respective test code like this:

#ifdef TEST_USB
int main(int argc, char *argv[]) {
  // the  main() routine for testing the usb code.
}

config.h Which is included by all the c files has an entry like this:

// Uncomment below to test the serial
//#define TEST_SERIAL


// Uncomment below to test the spi code
//#define TEST_SPI

// Uncomment below to test the usb code
#define TEST_USB

I think you should be able to follow the method used in this post. It looks really ugly, but I would think you could do it twice and get the result you want.

I wonder if this is actually a case where you'd be better off using DataContext.ExecuteCommand(...) instead of converting to linq.

Simply you can use HttpRequest.headers from Django 2.2 onward. Following example is directly taken from the official Django Documentation under Request and response objects section.

>>> request.headers
{'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6', ...}

>>> 'User-Agent' in request.headers
True
>>> 'user-agent' in request.headers
True

>>> request.headers['User-Agent']
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6)
>>> request.headers['user-agent']
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6)

>>> request.headers.get('User-Agent')
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6)
>>> request.headers.get('user-agent')
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6)

Just use jQuery's attr() method

$(this).closest("tr").next().show().find('.longboxsmall').attr('disabled', 'disabled');

You can also use:

$(window).bind("load", function() { 
    // Your code here.
});

This quote is taken from; Version Control with Git

Git runs garbage collection automatically:

• If there are too many loose objects in the repository

• When a push to a remote repository happens

• After some commands that might introduce many loose objects

• When some commands such as git reflog expire explicitly request it

And finally, garbage collection occurs when you explicitly request it using the git gc command. But when should that be? There’s no solid answer to this question, but there is some good advice and best practice.

You should consider running git gc manually in a few situations:

• If you have just completed a git filter-branch . Recall that filter-branch rewrites many commits, introduces new ones, and leaves the old ones on a ref that should be removed when you are satisfied with the results. All those dead objects (that are no longer referenced since you just removed the one ref pointing to them) should be removed via garbage collection.

• After some commands that might introduce many loose objects. This might be a large rebase effort, for example.

And on the flip side, when should you be wary of garbage collection?

• If there are orphaned refs that you might want to recover

• In the context of git rerere and you do not need to save the resolutions forever

• In the context of only tags and branches being sufficient to cause Git to retain a commit permanently

• In the context of FETCH_HEAD retrievals (URL-direct retrievals via git fetch ) because they are immediately subject to garbage collection

PUT THIS CODE IN YOUR XML FILE

<TextView
    android:id="@+id/textview1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

PUT THIS CODE IN YOUR JAVA FILE

// Declaring components like TextView globally is a good habit

TextView mTextView = (TextView) findViewById(R.id.textview1);

// Put this in OnCreate

mTextView.setText("Welcome to Dynamic TextView");

You can simply use datetime diff and format for calculating difference.

<?php
$datetime1 = new DateTime('2009-10-11 12:12:00');
$datetime2 = new DateTime('2009-10-13 10:12:00');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%Y-%m-%d %H:%i:%s');
?>

For more information OF DATETIME format, refer: here
You can change the interval format in the way,you want.

Here is the working example

P.S. These features( diff() and format()) work with >=PHP 5.3.0 only

These are identical for printf but different for scanf. For printf, both %d and %i designate a signed decimal integer. For scanf, %d and %i also means a signed integer but %i inteprets the input as a hexadecimal number if preceded by 0x and octal if preceded by 0 and otherwise interprets the input as decimal.

Password : password
Database : //123.45.67.89:1521/TEST

The answers above have already explained how setInterval returns a handle, and how this handle is used to cancel the Interval timer.

Some architectural considerations:

Please do not use "scope-less" variables. The safest way is to use the attribute of a DOM object. The easiest place would be "document". If the refresher is started by a start/stop button, you can use the button itself:

<a onclick="start(this);">Start</a>

<script>
function start(d){
    if (d.interval){
        clearInterval(d.interval);
        d.innerHTML='Start';
    } else {
        d.interval=setInterval(function(){
          //refresh here
        },10000);
        d.innerHTML='Stop';
    }
}
</script>

Since the function is defined inside the button click handler, you don't have to define it again. The timer can be resumed if the button is clicked on again.

The cleanest way is to test for it's existence, drop it if it exists, and then recreate it. You can't embed a "create proc" statement inside an IF statement. This should do nicely:

IF OBJECT_ID('MySproc', 'P') IS NOT NULL
DROP PROC MySproc
GO

CREATE PROC MySproc
AS
BEGIN
    ...
END

I have found out, that if you use the .getWidth/2 etc... that it won't work you need to get the number of pixels the image is and divide it by 2 yourself and then just type in the number for the last 2 arguments.

so say your image was a 120 pixel by 120 pixel square, ur x and y would equal 60 pixels. so in your code, you would right:

RotateAnimation anim = new RotateAnimation(0f, 350f, 60f, 60f);
anim.setInterpolator(new LinearInterpolator());
anim.setRepeatCount(Animation.INFINITE);
anim.setDuration(700);

and now your image will pivot round its center.

There are plenty of templating systems that offer more compact syntax for your views. Smarty is venerable and popular. This article lists 10 others.

Not with CSS, but you can emulate and extend / customize the desired behavior with JavaScript.

In C language, character literal is not a char type. C considers character literal as integer. So, there is no difference between sizeof('a') and sizeof(1).

So, the sizeof character literal is equal to sizeof integer in C.

In C++ language, character literal is type of char. The cppreference say's:

1) narrow character literal or ordinary character literal, e.g. 'a' or '\n' or '\13'. Such literal has type char and the value equal to the representation of c-char in the execution character set. If c-char is not representable as a single byte in the execution character set, the literal has type int and implementation-defined value.

So, in C++ character literal is a type of char. so, size of character literal in C++ is one byte.

Alos, In your programs, you have used wrong format specifier for sizeof operator.

C11 §7.21.6.1 (P9) :

If a conversion specification is invalid, the behavior is undefined.275) If any argument is not the correct type for the corresponding conversion specification, the behavior is undefined.

So, you should use %zu format specifier instead of %d, otherwise it is undefined behaviour in C.

I understand you've solved your issue, but for others reading this thread, here is the answer: you have to increase the stack that your operating system allocates for the python process.

The way to do it, is operating system dependant. In linux, you can check with the command ulimit -s your current value and you can increase it with ulimit -s <new_value>

Try doubling the previous value and continue doubling if it does not work, until you find one that does or run out of memory.

Edit 2020

Referring back to the (closed) github issue, where it is pointed out, there is no actual session or state;

docker login actually isn't creating any sort of persistent session, it is only storing the user's credentials on disk so that when authentication is required it can read them to login

As others have pointed out, an auths entry/node is added to the ~/.docker/config.json file (this also works for private registries) after you succesfully login:

{
    "auths": {
            "https://index.docker.io/v1/": {}
    },
    ...

When logging out, this entry is then removed:

$ docker logout
Removing login credentials for https://index.docker.io/v1/

Content of docker config.json after:

{
    "auths": {},
    ...

This file can be parsed by your script or code to check your login status.

Alternative method (re-login)

You can login to docker with docker login <repository>

$ docker login
Login with your Docker ID to push and pull images from Docker Hub. If 
you don't have a Docker ID, head over to https://hub.docker.com to 
create one.
Username:

If you are already logged in, the prompt will look like:

$ docker login
Login with your Docker ID to push and pull images from Docker Hub. If 
you don't have a Docker ID, head over to https://hub.docker.com to 
create one.
Username (myusername):        # <-- "myusername"

For the original explanation for the ~/.docker/config.json, check question: how can I tell if I'm logged into a private docker registry

you are confusing the concept of appending and prepending. the following code is prepending:

sys.path.insert(1,'/thePathToYourFolder/')

it places the new information at the beginning (well, second, to be precise) of the search sequence that your interpreter will go through. sys.path.append() puts things at the very end of the search sequence.

it is advisable that you use something like virtualenv instead of manually coding your package directories into the PYTHONPATH everytime. for setting up various ecosystems that separate your site-packages and possible versions of python, read these two blogs:

1. python ecosystems introduction

2. bootstrapping python virtual environments

if you do decide to move down the path to environment isolation you would certainly benefit by looking into virtualenvwrapper: http://www.doughellmann.com/docs/virtualenvwrapper/

Window > Preferences, go to the Run/Debug > Console section >> "Limit console output.>>Console buffer size(characters):" (This option can be seen in Eclipse Indigo ,but it limits buffer size at 1,000,000 )

I don't thinks that possible with a vanilla collection without storing the key values in an independent array.

The easiest alternative to do this is to add a reference to the Microsoft Scripting Runtime & use a more capable Dictionary instead:

Dim dict As Dictionary
Set dict = New Dictionary

dict.Add "key1", "value1"
dict.Add "key2", "value2"

Dim key As Variant
For Each key In dict.Keys
    Debug.Print "Key: " & key, "Value: " & dict.Item(key)
Next

I always put my scripts in the header. My reasons:

1. I like to separate code and (static) text
2. I usually load my script from external sources
3. The same script is used from several pages, so it feels like an include file (which also goes in the header)

Use find. Seriously, it is the best way because then you can really see what files it's operating on:

find . -name "*.sql" -exec grep -H "slow" {} \;

Note, the -H is mac-specific, it shows the filename in the results.

Well, did you DO what the error says? You go to some length telling about installation, but what about the obvious?

• Check the other server's network configuration in SQL Server.
• Check the other machines FIREWALL. SQL Server does not open ports automatically, so the windows firewall normally blocks access..

You really shouldn't need to use the numbers 1-1000 in a list. But if for some reason you really do need these numbers, then you could do:

[i for i in range(1, 1001)]

List Comprehension in a nutshell:

The above list comprehension translates to:

nums = []
for i in range(1, 1001):
    nums.append(i)

This is just the list comprehension syntax, though from 2.x. I know that this will work in python 3, but am not sure if there is an upgraded syntax as well

Range starts inclusive of the first parameter; but ends Up To, Not Including the second Parameter (when supplied 2 parameters; if the first parameter is left off, it'll start at '0')

range(start, end+1)
[start, start+1, .., end]

The Problem

There are a number of work-flows you can use. The main point is not to break history in a published branch unless you've communicated with everyone who might consume the branch and are willing to do surgery on everyone's clones. It's best not to do that if you can avoid it.

Solutions for Published Branches

Your outlined steps have merit. If you need the dev branch to be stable right away, do it that way. You have a number of tools for Debugging with Git that will help you find the right branch point, and then you can revert all the commits between your last stable commit and HEAD.

Either revert commits one at a time, in reverse order, or use the <first_bad_commit>..<last_bad_commit> range. Hashes are the simplest way to specify the commit range, but there are other notations. For example, if you've pushed 5 bad commits, you could revert them with:

# Revert a series using ancestor notation.
git revert --no-edit dev~5..dev

# Revert a series using commit hashes.
git revert --no-edit ffffffff..12345678

This will apply reversed patches to your working directory in sequence, working backwards towards your known-good commit. With the --no-edit flag, the changes to your working directory will be automatically committed after each reversed patch is applied.

See man 1 git-revert for more options, and man 7 gitrevisions for different ways to specify the commits to be reverted.

Alternatively, you can branch off your HEAD, fix things the way they need to be, and re-merge. Your build will be broken in the meantime, but this may make sense in some situations.

The Danger Zone

Of course, if you're absolutely sure that no one has pulled from the repository since your bad pushes, and if the remote is a bare repository, then you can do a non-fast-forward commit.

git reset --hard <last_good_commit>
git push --force

This will leave the reflog intact on your system and the upstream host, but your bad commits will disappear from the directly-accessible history and won't propagate on pulls. Your old changes will hang around until the repositories are pruned, but only Git ninjas will be able to see or recover the commits you made by mistake.

I'm a little late to the party but the following is a language-agnostic approach which doesn't use GOTO/labels or function wrapping:

for (var x = Set1.length; x > 0; x--)
{
   for (var y = Set2.length; y > 0; y--)
   {
      for (var z = Set3.length; z > 0; z--)
      {
          z = y = -1; // terminates second loop
          // z = y = x = -1; // terminate first loop
      }
   }
}

On the upside it flows naturally which should please the non-GOTO crowd. On the downside, the inner loop needs to complete the current iteration before terminating so it might not be applicable in some scenarios.

Looking at the edited question, you need to find the number of digits in the largest number to be presented, and then generate the printf() format using sprintf(), or using %*d with the number of digits being passed as an int for the * and then the value. Once you've got the biggest number (and you have to determine that in advance), you can determine the number of digits with an 'integer logarithm' algorithm (how many times can you divide by 10 before you get to zero), or by using snprintf() with the buffer length of zero, the format %d and null for the string; the return value tells you how many characters would have been formatted.

If you don't know and cannot determine the maximum number ahead of its appearance, you are snookered - there is nothing you can do.

This works for me:

android:focusable="false"

I made following changes in web.config to get the SOAP (Request/Response) Envelope. This will output all of the raw SOAP information to the file trace.log.

Below are 2 simple functions for converting Uint8Array to Base64 String and back again

arrayToBase64String(a) {
    return btoa(String.fromCharCode(...a));
}

base64StringToArray(s) {
    let asciiString = atob(s);
    return new Uint8Array([...asciiString].map(char => char.charCodeAt(0)));
}

This is another approach

void remove_duplicate (char* str, int len) {
    unsigned int index = 0;
    int c = 0;
    int i = 0;
    while (c < len) {
        /* this is just example more check can be added for
           capital letter, space and special chars */

        int pos = str[c] - 'a';
        if ((index & (1<<pos)) == 0) {
            str[i++] = str[c];
            index |= (1<<pos);
        }
        c++;
    }
    str[i] = 0;
}

I faced the same issue and got it working.

I think it is because when you import a project, build target is not set in the project properties which then default to the value used in manifest file. Most likely, you already have installed a later android API with your SDK.

The solution is to enable build target toward your installed API level (but keep the minimum api support as specified in the manifest file). TO do this, in project properties, go to android, and from "Project Build Target", pick a target name.

The standard MIME type is application/pdf. The assignment is defined in RFC 3778, The application/pdf Media Type, referenced from the MIME Media Types registry.

MIME types are controlled by a standards body, The Internet Assigned Numbers Authority (IANA). This is the same organization that manages the root name servers and the IP address space.

The use of x-pdf predates the standardization of the MIME type for PDF. MIME types in the x- namespace are considered experimental, just as those in the vnd. namespace are considered vendor-specific. x-pdf might be used for compatibility with old software.

Use this code it will help you.

function InitializeDate() {
    var date = new Date();
    var dd = date.getDate();             
    var mm = date.getMonth() + 1;
    var yyyy = date.getFullYear();

    var ToDate = mm + '/' + dd + '/' + yyyy;
    var FromDate = mm + '/01/' + yyyy;
    $('#txtToDate').datepicker('setDate', ToDate);
    $('#txtFromDate').datepicker('setDate', FromDate);

If it's a .mdf database and the connection string was saved when it was created, you should be able to access it via:

Note: This is with regards to MySQL Workbench 6.3.9

Pythont 3.5 added the methods run() and call() to the subprocess module, both returning a CompletedProcess object. With this you are fine using proc.stdout.splitlines():

proc = subprocess.run( comman, shell=True, capture_output=True, text=True, check=True )
for line in proc.stdout.splitlines():
   print "stdout:", line

This might be more useful when you want your index shuffled.

def shuffle(df):
    index = list(df.index)
    random.shuffle(index)
    df = df.ix[index]
    df.reset_index()
    return df

It selects new df using new index, then reset them.

There are many differences between ListView and RecyclerView, but you should be aware of the following in particular:

• The ViewHolder pattern is entirely optional in ListView, but it’s baked into RecyclerView.
• ListView only supports vertical scrolling, but RecyclerView isn’t limited to vertically scrolling lists.

I can strongly recommend the aspNetEmail library: http://www.aspnetemail.com/

The System.Net.Mail will get you somewhere if your needs are only basic, but if you run into trouble, please check out aspNetEmail. It has saved me a bunch of time, and I know of other develoeprs who also swear by it!

I was getting the same error "com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'mylocaldb.hibernate_sequence' doesn't exist".

Using spring mvc 4.3.7 and hibernate version 5.2.9, application is made using spring java based configuration. Now I have to add the hibernate.id.new_generator_mappings property mentioned by @Eva Mariam in my code like this:

@Autowired
    @Bean(name = "sessionFactory")
    public SessionFactory getSessionFactory(DataSource dataSource) {

        LocalSessionFactoryBuilder sessionBuilder = new LocalSessionFactoryBuilder(dataSource);
        sessionBuilder.addProperties(getHibernateProperties());
        sessionBuilder.addAnnotatedClasses(User.class);

        return sessionBuilder.buildSessionFactory();
    }

    private Properties getHibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.show_sql", "true");
        properties.put("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
        properties.put("hibernate.id.new_generator_mappings","false");
        return properties;
    }

And it worked like charm.

try this, hope it will help you to get the current location, every time the location changes.

public class MyClass implements LocationListener {
    double currentLatitude, currentLongitude;

    public void onLocationChanged(Location location) {
        currentLatitude = location.getLatitude();
        currentLongitude = location.getLongitude();
    }
}

How can I find all subclasses of a class given its name?

We can certainly easily do this given access to the object itself, yes.

Simply given its name is a poor idea, as there can be multiple classes of the same name, even defined in the same module.

I created an implementation for another answer, and since it answers this question and it's a little more elegant than the other solutions here, here it is:

def get_subclasses(cls):
    """returns all subclasses of argument, cls"""
    if issubclass(cls, type):
        subclasses = cls.__subclasses__(cls)
    else:
        subclasses = cls.__subclasses__()
    for subclass in subclasses:
        subclasses.extend(get_subclasses(subclass))
    return subclasses

Usage:

>>> import pprint
>>> list_of_classes = get_subclasses(int)
>>> pprint.pprint(list_of_classes)
[<class 'bool'>,
 <enum 'IntEnum'>,
 <enum 'IntFlag'>,
 <class 'sre_constants._NamedIntConstant'>,
 <class 'subprocess.Handle'>,
 <enum '_ParameterKind'>,
 <enum 'Signals'>,
 <enum 'Handlers'>,
 <enum 'RegexFlag'>]

I think this code will work because a placeholder is needed only for input type text. So this one line CSS will be enough for your need:

input[type="text"]::-webkit-input-placeholder {
    color: red;
}

I'm pretty sure you should go with bar(); because with foo(); it creates a List (for nothing) since you create a new File[0] in the end anyway, so why not go with directly returning it!

INSERT INTO Table2 SELECT DISTINCT ID,Data = STUFF((SELECT ', ' + AA.Data FROM Table1 AS AA WHERE AA.ID = BB.ID FOR XML PATH(''), TYPE).value('.','nvarchar(max)'), 1, 2, '') FROM Table1 AS BB 
GROUP BY ID,Data
ORDER BY ID;

You can do this:

1. Change the package name manually in the manifest file.
2. Click on your R.java class and the press F6 (Refactor->Move...). It will allow you to move the class to another package, and all references to that class will be updated.

After looking for an answer for the question for months, I finally find a really best solution: writing a simple script.

#!/usr/bin/expect

set timeout 20

set cmd [lrange $argv 1 end]
set password [lindex $argv 0]

eval spawn $cmd
expect "assword:"   # matches both 'Password' and 'password'
send "$password\r";
interact

Put it to /usr/bin/exp, then you can use:

• exp <password> ssh <anything>
• exp <password> scp <anysrc> <anydst>

Done!

Both the mongod (database server) and mongo (database client shell) programs are command line programs and each expects to be run in its own command line session. So, after starting the server (as you did with "./mongod") you should open a second command line session and run "./mongo" in it to give you a command line shell for talking to the server.

Use this..

$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
    $res_arr_values[] = $row;
}

Ok, I know that this question is actually solved but I decided to share my solution for this. I've created abstract parent class for my Fragment:

public abstract class ABaseFragment extends Fragment{

    protected IActivityEnabledListener aeListener;

    protected interface IActivityEnabledListener{
        void onActivityEnabled(FragmentActivity activity);
    }

    protected void getAvailableActivity(IActivityEnabledListener listener){
        if (getActivity() == null){
            aeListener = listener;

        } else {
            listener.onActivityEnabled(getActivity());
        }
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);

        if (aeListener != null){
            aeListener.onActivityEnabled((FragmentActivity) activity);
            aeListener = null;
        }
    }

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);

        if (aeListener != null){
            aeListener.onActivityEnabled((FragmentActivity) context);
            aeListener = null;
        }
    }
}

As you can see, I've added a listener so, whenever I'll need to get Fragments Activity instead of standard getActivity(), I'll need to call

 getAvailableActivity(new IActivityEnabledListener() {
        @Override
        public void onActivityEnabled(FragmentActivity activity) {
            // Do manipulations with your activity
        }
    });

I would try the program screen.

There is an amazing library called SwipeCellKit, it should gain more acknowledgement. In my opinion it is cooler than MGSwipeTableCell. The latter doesn't completely replicate the behavior of the Mail app's cells whereas SwipeCellKit does. Have a look

     .keypress(function(e)
               {
                 var key_codes = [48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 0, 8];

                 if (!($.inArray(e.which, key_codes) >= 0)) {
                   e.preventDefault();
                 }
               });

Edit: I guess you are looking for something to use in insert mode. Strangely enough, there is nothing to be found in the docs, ctrl-w seems to be all there is.

There are two issues here.

Firstly, you can't use the [] syntax like you may be able to in other languages. Square brackets only apply to arrays in Java, and so can only be used with integer indexes.

data.put is correct but that is a statement and so must exist in a method block. Only field declarations can exist at the class level. Here is an example where everything is within the local scope of a method:

public class Data {
     public static void main(String[] args) {
         Map<String, String> data = new HashMap<String, String>();
         data.put("John", "Taxi Driver");
         data.put("Mark", "Professional Killer");
     }
 }

If you want to initialize a map as a static field of a class then you can use Map.of, since Java 9:

public class Data {
    private static final Map<String, String> DATA = Map.of("John", "Taxi Driver");
}

Before Java 9, you can use a static initializer block to accomplish the same thing:

public class Data {
    private static final Map<String, String> DATA = new HashMap<>();

    static {
        DATA.put("John", "Taxi Driver");
    }
}

SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
sdf.format(new Date());

This should do the trick

A generic answer on how to handle click events with KnockoutJS...

Not a straight up answer to the question as asked, but probably an answer to the question most Googlers landing here have: use the click binding from KnockoutJS instead of onclick. Like this:

function Item(parent, txt) {_x000D_
  var self = this;_x000D_
  _x000D_
  self.doStuff = function(data, event) {_x000D_
    console.log(data, event);_x000D_
    parent.log(parent.log() + "\n  data = " + ko.toJSON(data));_x000D_
  };_x000D_
  _x000D_
  self.doOtherStuff = function(customParam, data, event) {_x000D_
    console.log(data, event);_x000D_
    parent.log(parent.log() + "\n  data = " + ko.toJSON(data) + ", customParam = " + customParam);_x000D_
  };_x000D_
  _x000D_
  self.txt = ko.observable(txt);_x000D_
}_x000D_
_x000D_
function RootVm(items) {_x000D_
  var self = this;_x000D_
  _x000D_
  self.doParentStuff = function(data, event) {_x000D_
    console.log(data, event);_x000D_
    self.log(self.log() + "\n  data = " + ko.toJSON(data));_x000D_
  };_x000D_
  _x000D_
  self.items = ko.observableArray([_x000D_
    new Item(self, "John Doe"),_x000D_
    new Item(self, "Marcus Aurelius")_x000D_
  ]);_x000D_
  self.log = ko.observable("Started logging...");_x000D_
}_x000D_
_x000D_
ko.applyBindings(new RootVm());

.parent { background: rgba(150, 150, 200, 0.5); padding: 2px; margin: 5px; }_x000D_
button { margin: 2px 0; font-family: consolas; font-size: 11px; }_x000D_
pre { background: #eee; border: 1px solid #ccc; padding: 5px; }

**A note about the actual question...*

The actual question has one interesting bit:

// Uh oh! Modifying the DOM....
place.innerHTML = "somthing"

Don't do that! Don't modify the DOM like that when using an MVVM framework like KnockoutJS, especially not the piece of the DOM that is your own parent. If you would do this the button would disappear (if you replace your parent's innerHTML you yourself will be gone forever ever!).

Instead, modify the View Model in your handler instead, and have the View respond. For example:

function RootVm() {_x000D_
  var self = this;_x000D_
  self.buttonWasClickedOnce = ko.observable(false);_x000D_
  self.toggle = function(data, event) {_x000D_
    self.buttonWasClickedOnce(!self.buttonWasClickedOnce());_x000D_
  };_x000D_
}_x000D_
_x000D_
ko.applyBindings(new RootVm());

<script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.0/knockout-min.js"></script>_x000D_
_x000D_
<div>_x000D_
  <div  data-bind="visible: !buttonWasClickedOnce()">_x000D_
    <button data-bind="click: toggle">Toggle!</button>_x000D_
  </div>_x000D_
  <div data-bind="visible: buttonWasClickedOnce">_x000D_
    Can be made visible with toggle..._x000D_
    <button data-bind="click: toggle">Untoggle!</button>_x000D_
  </div>_x000D_
</div>

In my own words, after reading the docs and experimenting:

You can use RewriteBase to provide a base for your rewrites. Consider this

# invoke rewrite engine
    RewriteEngine On
    RewriteBase /~new/

# add trailing slash if missing
    rewriteRule ^(([a-z0-9\-]+/)*[a-z0-9\-]+)$ $1/ [NC,R=301,L]

This is a real rule I used to ensure that URLs have a trailing slash. This will convert

http://www.example.com/~new/page

to

http://www.example.com/~new/page/

By having the RewriteBase there, you make the relative path come off the RewriteBase parameter.

I found the right answer to this one. Try TCPView from Sysinternals, now owned by Microsoft. You can find it at http://technet.microsoft.com/en-us/sysinternals/bb897437

I used the following solution:

1. Convert .svg image to JSX with https://svg2jsx.herokuapp.com/
2. Convert the JSX to react-native-svg component with https://svgr.now.sh/ (check the "React Native checkbox)

[ round(x,2) for x in [2.15295647e+01, 8.12531501e+00, 3.97113829e+00, 1.00777250e+01]]

The answer about "short-circuiting" is potentially misleading, but has some truth (see below). In the R/S language, && and || only evaluate the first element in the first argument. All other elements in a vector or list are ignored regardless of the first ones value. Those operators are designed to work with the if (cond) {} else{} construction and to direct program control rather than construct new vectors.. The & and the | operators are designed to work on vectors, so they will be applied "in parallel", so to speak, along the length of the longest argument. Both vectors need to be evaluated before the comparisons are made. If the vectors are not the same length, then recycling of the shorter argument is performed.

When the arguments to && or || are evaluated, there is "short-circuiting" in that if any of the values in succession from left to right are determinative, then evaluations cease and the final value is returned.

> if( print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(FALSE && print(1) ) {print(2)} else {print(3)} # `print(1)` not evaluated
[1] 3
> if(TRUE && print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(TRUE && !print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 3
> if(FALSE && !print(1) ) {print(2)} else {print(3)}
[1] 3

The advantage of short-circuiting will only appear when the arguments take a long time to evaluate. That will typically occur when the arguments are functions that either process larger objects or have mathematical operations that are more complex.

It can also happen when drawing a new (other) table. I solved this by first removing the previous table:

$("#prod_tabel_ph").remove();

If you don't need to support IE8 then you can use the native Javascript Array.prototype.reduce() method. You will need to convert your JQuery object into an array first:

 var sum = $('.price').toArray().reduce(function(sum,element) {
     if(isNaN(sum)) sum = 0;
     return sum + Number(element.value);
 }, 0);

Here's a couple ways to do this using the Joda-Time 2.3 library.

One way is to use the simple isBefore and isAfter methods on DateTime instances. By the way, DateTime in Joda-Time is similar in concept to a java.util.Date (a moment in time on the timeline of the Universe) but includes a time zone.

Another way is to build an Interval in Joda-Time. The contains method tests if a given DateTime occurs within the span of time covered by the Interval. The beginning of the Interval is inclusive, but the endpoint is exclusive. This approach is known as "Half-Open", symbolically [).

See both ways in the following code example.

Convert the java.util.Date instances to Joda-Time DateTime instances. Simply pass the Date instance to constructor of DateTime. In practice you should also pass a specific DateTimeZone object rather than rely on JVM’s default time zone.

DateTime dateTime1 = new DateTime( new java.util.Date() ).minusWeeks( 1 );
DateTime dateTime2 = new DateTime( new java.util.Date() );
DateTime dateTime3 = new DateTime( new java.util.Date() ).plusWeeks( 1 );

Compare by testing for before/after…

boolean is1After2 = dateTime1.isAfter( dateTime2 );
boolean is2Before3 = dateTime2.isBefore( dateTime3 );

boolean is2Between1And3 = ( ( dateTime2.isAfter( dateTime1 ) ) && ( dateTime2.isBefore( dateTime3 ) ) );

Using the Interval approach instead of isAfter/isBefore…

Interval interval = new Interval( dateTime1, dateTime3 );
boolean intervalContainsDateTime2 = interval.contains( dateTime2 );

Dump to console…

System.out.println( "DateTimes: " + dateTime1 + " " + dateTime1 + " " + dateTime1 );
System.out.println( "is1After2 " + is1After2 );
System.out.println( "is2Before3 " + is2Before3 );
System.out.println( "is2Between1And3 " + is2Between1And3 );
System.out.println( "intervalContainsDateTime2 " + intervalContainsDateTime2 );

When run…

DateTimes: 2014-01-22T20:26:14.955-08:00 2014-01-22T20:26:14.955-08:00 2014-01-22T20:26:14.955-08:00
is1After2 false
is2Before3 true
is2Between1And3 true
intervalContainsDateTime2 true

My IDE left a mix of spaces and tabs in my Makefile.

Setting my Makefile to use only tabs fixed this error for me.

Kotlin Style way to do this more simple (example):

    isVisible = false

Complete example:

    if (some_data_array.details == null){
                holder.view.some_data_array.isVisible = false}

System.exit(); causes the Java VM to terminate completely.

JFrame.dispose(); causes the JFrame window to be destroyed and cleaned up by the operating system. According to the documentation, this can cause the Java VM to terminate if there are no other Windows available, but this should really just be seen as a side effect rather than the norm.

The one you choose really depends on your situation. If you want to terminate everything in the current Java VM, you should use System.exit() and everything will be cleaned up. If you only want to destroy the current window, with the side effect that it will close the Java VM if this is the only window, then use JFrame.dispose().

$('li[rel=7]').siblings().andSelf();

// or:

$('li[rel=7]').parent().children();

Now that you added that comment explaining that you want to "form an array of rels per column", you should do this:

var rels = [];

$('ul').each(function() {
    var localRels = [];

    $(this).find('li').each(function(){
        localRels.push( $(this).attr('rel') );
    });

    rels.push(localRels);
});

I had the same problem, put the ! outside the brackets;

while ! [ -f /tmp/list.txt ];
do
    echo "#"
    sleep 1
done

Also, if you add an echo inside the loop it will tell you if you are getting into the loop or not.

To centre align a div you should apply the style

div 
{
    margin: 0 auto;
}

As Nayan said the Path has to updated properly in my case the apache-maven was installed in C:\apache-maven and settings.xml was found inside C:\apache-maven\conf\settings.xml

if this doesn't work go to your local repos
in my case C:\Users\<<"name">>.m2\
and search for .lastUpdated and delete them
then build the maven

As MultiPartEntity is deprecated. So here is the new way to do it! And you only need httpcore.jar(latest) and httpmime.jar(latest) download them from Apache site.

try
{
    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(URL);

    MultipartEntityBuilder entityBuilder = MultipartEntityBuilder.create();
    entityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

    entityBuilder.addTextBody(USER_ID, userId);
    entityBuilder.addTextBody(NAME, name);
    entityBuilder.addTextBody(TYPE, type);
    entityBuilder.addTextBody(COMMENT, comment);
    entityBuilder.addTextBody(LATITUDE, String.valueOf(User.Latitude));
    entityBuilder.addTextBody(LONGITUDE, String.valueOf(User.Longitude));

    if(file != null)
    {
        entityBuilder.addBinaryBody(IMAGE, file);
    }

    HttpEntity entity = entityBuilder.build();
    post.setEntity(entity);
    HttpResponse response = client.execute(post);
    HttpEntity httpEntity = response.getEntity();
    result = EntityUtils.toString(httpEntity);
    Log.v("result", result);
}
catch(Exception e)
{
    e.printStackTrace();
}

For those who want to put color in String.xml directly and don't want to use color...

example

<string name="status_stop"><font fgcolor='#FF8E8E93'>Stopped</font></string> <!--gray-->
<string name="status_running"><font fgcolor='#FF4CD964'>Running</font></string> <!--green-->
<string name="status_error"><font fgcolor='#FFFF3B30'>Error</font></string> <!--red-->

as you see there is gray, red, and green, there is 8 characters, first two for transparency and other for color.

Example

This a description of color and transparency
#   FF               FF3B30    
    Opacity          Color

Note: Put color in text in the same string.xml will not work in Android 6.0 and above

Reference: Understanding colors in Android (6 characters)

Update: 10/OCT/2016

This function is compatible with all version of android, I didn't test in android 7.0. Use this function to get color and set in textview

Example format xml in file string and colors

<!-- /res/values/strings.xml -->
<string name="status_stop">Stopped</string>
<string name="status_running">Running</string>
<string name="status_error">Error</string>

<!-- /res/values/colors.xml -->
<color name="status_stop">#8E8E93</color>
<color name="status_running">#4CD964</color>
<color name="status_error">#FF3B30</color>

Function to get color from xml with validation for android 6.0 and above

public static int getColorWrapper(Context context, int id) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {//if actual version is >= 6.0
            return context.getColor(id);
        } else {
            //noinspection deprecation
            return context.getResources().getColor(id);
        }
    }

Example:

TextView status = (TextView)findViewById(R.id.tvstatus);
status.setTextColor(getColorWrapper(myactivity.this,R.color.status_stop));

Reference: getColor(int id) deprecated on Android 6.0 Marshmallow (API 23)

I stumbled upon the same problem: a page with many independent animations, each one with its own parameters, which must be repeated forever.

Merging this clue with this other clue I found an easy solution: after the end of all your animations the wrapping div is restored, forcing the animations to restart.

All you have to do is to add these few lines of Javascript, so easy they don't even need any external library, in the <head> section of your page:

<script>
setInterval(function(){
var container = document.getElementById('content');
var tmp = container.innerHTML;
container.innerHTML= tmp;
}, 35000 // length of the whole show in milliseconds
);
</script>

BTW, the closing </head> in your code is misplaced: it must be before the starting <body>.

var ids = [];

    $(document).ready(function($) {    
    $(".color_cell").bind('click', function() {
        alert('Test');

        ids.push(this.id);       
    });
});

In Eclipse when can do this:

But it is preferable make the corresponding changes inside the Android manifest file.

You can use:

if (parentGuest.nextSibling) {
  parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);
}
else {
  parentGuest.parentNode.appendChild(childGuest);
}

But as Pavel pointed out, the referenceElement can be null/undefined, and if so, insertBefore behaves just like appendChild. So the following is equivalent to the above:

parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);

If you have SQL Server installed there is also a menu option for finding local SSIS packages.

In the Start menu > All Programs > 'Microsoft Sql Server' there should be a menu option for 'Integration Services' > 'Execute Package Utility' (this is available if SSIS was included in your SQLserver installation).

When you open the Execute Package Utility, type your local sql server name in the 'Server Name' textbox and click on the Package button, you will see your saved package in the popup window. From here you can run your previously saved package

If you set { responseType: 'blob' }, no need to create Blob on your own. You can simply create url based with response content:

$http({
    url: "...",
    method: "POST",
    responseType: "blob"
}).then(function(response) {
    var fileURL = URL.createObjectURL(response.data);
    window.open(fileURL);
});

For showing Forbidden error then include these lines in your .htaccess file:

Options -Indexes 

If we want to index our files and showing them with some information, then use:

IndexOptions -FancyIndexing

If we want for some particular extension not to show, then:

IndexIgnore *.zip *.css

Please find below example using Selenium "until.stalenessOf" and Jasmine assertion. It returns true when element is no longer attached to the DOM.

const { Builder, By, Key, until } = require('selenium-webdriver');

it('should not find element', async () => {
   const waitTime = 10000;
   const el = await driver.wait( until.elementLocated(By.css('#my-id')), waitTime);
   const isRemoved = await driver.wait(until.stalenessOf(el), waitTime);

   expect(isRemoved).toBe(true);
});

For ref.: Selenium:Until Doc

If you're looking to compare times, and not the dates, you could just have a standard comparison date, or match to the date you're using, as in...

DateTime time = DateTime.Parse("6/22/2009 10:00AM");
DateTime compare = DateTime.Parse(time.ToShortDateString() + " 2:00PM");
bool greater = (time > compare);

There may be better ways to to this, but keeps your dates matching.

wget --spider -S "http://url/to/be/checked" 2>&1 | grep "HTTP/" | awk '{print $2}'

prints only the status code for you

If the attribute you want to change doesn't exist or has been accidentally removed, then an exception occurs. I suggest you first create a new attribute and send it to a function like the following:

private void SetAttrSafe(XmlNode node,params XmlAttribute[] attrList)
    {
        foreach (var attr in attrList)
        {
            if (node.Attributes[attr.Name] != null)
            {
                node.Attributes[attr.Name].Value = attr.Value;
            }
            else
            {
                node.Attributes.Append(attr);
            }
        }
    }

Usage:

   XmlAttribute attr = dom.CreateAttribute("name");
   attr.Value = value;
   SetAttrSafe(node, attr);

Here you can find some public REST services for encryption and security related things: http://security.jelastic.servint.net

You can also use formatDate

let formattedDt = formatDate(new Date(), 'yyyy-MM-dd hh:mm:ssZZZZZ', 'en_US')

These links explain it with examples

http://dotnetperls.com/openfiledialog

http://www.geekpedia.com/tutorial67_Using-OpenFileDialog-to-open-files.html

private void button1_Click(object sender, EventArgs e)
{
    int size = -1;
    DialogResult result = openFileDialog1.ShowDialog(); // Show the dialog.
    if (result == DialogResult.OK) // Test result.
    {
       string file = openFileDialog1.FileName;
       try
       {
          string text = File.ReadAllText(file);
          size = text.Length;
       }
       catch (IOException)
       {
       }
    }
    Console.WriteLine(size); // <-- Shows file size in debugging mode.
    Console.WriteLine(result); // <-- For debugging use.
}

String can be converted to numbers in MongoDB v4.0 using $toInt operator. In this case

db.col.aggregate([
    {
        $project: {
            _id: 0,
            moopNumber: { $toInt: "$moop" }
        }
    }
])

outputs:

{ "moopNumber" : 1234 }

Use the SqlDataAdapter, this would simplify everything.

//Your code to this point
DataTable dt = new DataTable();

using(var cmd = new SqlCommand("usp_GetABCD", sqlcon))
{
  using(var da = new SqlDataAdapter(cmd))
  {
      da.Fill(dt):
  }
}

and your DataTable will have the information you are looking for, so long as your stored proceedure returns a data set (cursor).

For anyone using Koa and koa-passport:

Know that the key for the user set in the serializeUser method (often a unique id for that user) will be stored in:

this.session.passport.user

When you set in done(null, user) in deserializeUser where 'user' is some user object from your database:

this.req.user OR this.passport.user

for some reason this.user Koa context never gets set when you call done(null, user) in your deserializeUser method.

So you can write your own middleware after the call to app.use(passport.session()) to put it in this.user like so:

app.use(function * setUserInContext (next) {
  this.user = this.req.user
  yield next
})

If you're unclear on how serializeUser and deserializeUser work, just hit me up on twitter. @yvanscher

Have you set up a python interpreter facet?

Open Project Structure CTRL+ALT+SHIFT+S

Project settings -> Facets -> expand Python click on child -> Python Interpreter

Then:

Project settings -> Modules -> Expand module -> Python -> Dependencies -> select Python module SDK

Use the &#215 code instead of &times Because JSF don't understand the × code.

Use: &#215 with ;

This link provides some additional information about the topic.

Try os.path.splitext it should do what you want.

import os
print os.path.splitext('/home/user/somefile.txt')[0]+'.jpg'

Ctrl+] - go to definition
Ctrl+T - Jump back from the definition.
Ctrl+W Ctrl+] - Open the definition in a horizontal split

Add these lines in vimrc
map <C-\> :tab split<CR>:exec("tag ".expand("<cword>"))<CR>
map <A-]> :vsp <CR>:exec("tag ".expand("<cword>"))<CR>

Ctrl+\ - Open the definition in a new tab
Alt+] - Open the definition in a vertical split

After the tags are generated. You can use the following keys to tag into and tag out of functions:

Ctrl+Left MouseClick - Go to definition
Ctrl+Right MouseClick - Jump back from definition

Those curly things are sometimes hard to remember, that's why there's excellent documentation:

// Declare a single-dimensional array  
int[] array1 = new int[5];

Press Ctrl+Alt+Shift+S in android studio or go to File > Project Structure... Select app on left side and select falvors tab on right side on default config change version code , name and etc...

https://gist.github.com/db0company/369bfa43cb84b145dfd8 I did some tests on the answers and comments on this site. For me, the following works

extension UIViewController {
    func topMostViewController() -> UIViewController {

        if let presented = self.presentedViewController {
            return presented.topMostViewController()
        }

        if let navigation = self as? UINavigationController {
            return navigation.visibleViewController?.topMostViewController() ?? navigation
        }

        if let tab = self as? UITabBarController {
            return tab.selectedViewController?.topMostViewController() ?? tab
    }

        return self
    }
}

extension UIApplication {
    func topMostViewController() -> UIViewController? {
        return self.keyWindow?.rootViewController?.topMostViewController()
    }
}

Then, get the top viewController by:

UIApplication.shared.topMostViewController()

You could make two forms with 2 different actions

<form action="login.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Login">
</form>

<br />

<form action="register.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Register">
</form>

Or do this

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="login">
    <input type="submit" value="Login">
</form>

<br />

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="register">
    <input type="submit" value="Register">
</form>

Then you PHP file would work as a switch($_POST['action']) ... furthermore, they can't click on both links at the same time or make a simultaneous request, each submit is a separate request.

Your PHP would then go on with the switch logic or have different php files doing a login procedure then a registration procedure
