Another option would be to use the File Explorer in DDMS (Eclipse SDK), you can see the whole file system there and download/upload files to the desired place. That way you don't have to mount and deal with images. Just remember to set your device as USB debuggable (from Developer Tools)

For .NET 4.6.2 or lower, .NET Core 1.x, and .NET Standard 1.x you need to install the NuGet package System.ValueTuple:

Install-Package "System.ValueTuple"

Or using a package reference in VS 2017:

<PackageReference Include="System.ValueTuple" Version="4.4.0" />

.NET Framework 4.7, .NET Core 2.0, and .NET Standard 2.0 include these types.

You have to turn on the ability to add the formatter tags. In the menubar go to:

Windows → Preferences Java → Code Style → Formatter

Press the Edit button. Choose the last tab. Notice the On/Off box and enable them with a checkbox.

1. While Angular 1 was a framework, Angular 2 is a platform. (ref)

To developers, Angular2 provides some features beyond showing data on screen. For example, using angular2 cli tool can help you "pre-compile" your code and generate necessary javascript code (tree-shaking) to shrink the download size down to 35Kish.

2. Angular2 emulated Shadow DOM. (ref)

This opens a door for server rendering that can address SEO issue and work with Nativescript etc that don't work on browsers.

• The official document site

• Day one keynote from ng-conf 2016

• Resource links Original: Basically, jQuery is a great tool for you to manipulate and control DOM elements. If you only focus on DOM elements and no Data CRUD, like building a website not web application, jQuery is the one of the top tools. (You can use AngularJS for this purpose as well.)

AngularJS is a framework. It has following features

1. Two way data binding
2. MVW pattern (MVC-ish)
3. Template
4. Custom-directive (reusable components, custom markup)
5. REST-friendly
6. Deep Linking (set up a link for any dynamic page)
7. Form Validation
8. Server Communication
9. Localization
10. Dependency injection
11. Full testing environment (both unit, e2e)

You can use jQuery with AngularJS without any issue.

In fact, AngularJS uses jQuery lite in it, which is a great tool.

From FAQ

Does Angular use the jQuery library?

Yes, Angular can use jQuery if it's present in your app when the application is being bootstrapped. If jQuery is not present in your script path, Angular falls back to its own implementation of the subset of jQuery that we call jQLite.

However, don't try to use jQuery to modify the DOM in AngularJS controllers, do it in your directives.

Update:

Angular2 is released. Here is a great list of resource for starters

There's a RemoveDuplicates method that you could use:

Sub DeleteRows()

    With ActiveSheet
        Set Rng = Range("A1", Range("B1").End(xlDown))
        Rng.RemoveDuplicates Columns:=Array(1, 2), Header:=xlYes
    End With

End Sub

I don't know what you mean by 'manually'. You can choose a colourmap and make a colour array easily enough:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cm as cm

x = np.arange(10)
ys = [i+x+(i*x)**2 for i in range(10)]

colors = cm.rainbow(np.linspace(0, 1, len(ys)))
for y, c in zip(ys, colors):
    plt.scatter(x, y, color=c)

Or you can make your own colour cycler using itertools.cycle and specifying the colours you want to loop over, using next to get the one you want. For example, with 3 colours:

import itertools

colors = itertools.cycle(["r", "b", "g"])
for y in ys:
    plt.scatter(x, y, color=next(colors))

Come to think of it, maybe it's cleaner not to use zip with the first one neither:

colors = iter(cm.rainbow(np.linspace(0, 1, len(ys))))
for y in ys:
    plt.scatter(x, y, color=next(colors))

I've written a very simple router abstraction on top of History.js, called StateRouter.js. It's in very early stages of development, but I am using it as the routing solution in a single-page application I'm writing. Like you, I found History.js very hard to grasp, especially as I'm quite new to JavaScript, until I understood that you really need (or should have) a routing abstraction on top of it, as it solves a low-level problem.

This simple example code should demonstrate how it's used:

var router = new staterouter.Router();
// Configure routes
router
  .route('/', getHome)
  .route('/persons', getPersons)
  .route('/persons/:id', getPerson);
// Perform routing of the current state
router.perform();

Here's a little fiddle I've concocted in order to demonstrate its usage.

If anyone still has problem, this is my code.

I have a custom view which is square (width = height) and I want to assign a character to it. onDraw() shows how to get height of character, although I'm not using it. Character will be displayed in the middle of view.

public class SideBarPointer extends View {

    private static final String TAG = "SideBarPointer";

    private Context context;
    private String label = "";
    private int width;
    private int height;

    public SideBarPointer(Context context) {
        super(context);
        this.context = context;
        init();
    }

    public SideBarPointer(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.context = context;
        init();
    }

    public SideBarPointer(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        this.context = context;
        init();
    }

    private void init() {
//        setBackgroundColor(0x64FF0000);
    }

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        height = this.getMeasuredHeight();
        width = this.getMeasuredWidth();

        setMeasuredDimension(width, width);
    }

    protected void onDraw(Canvas canvas) {
        float mDensity = context.getResources().getDisplayMetrics().density;
        float mScaledDensity = context.getResources().getDisplayMetrics().scaledDensity;

        Paint previewPaint = new Paint();
        previewPaint.setColor(0x0C2727);
        previewPaint.setAlpha(200);
        previewPaint.setAntiAlias(true);

        Paint previewTextPaint = new Paint();
        previewTextPaint.setColor(Color.WHITE);
        previewTextPaint.setAntiAlias(true);
        previewTextPaint.setTextSize(90 * mScaledDensity);
        previewTextPaint.setShadowLayer(5, 1, 2, Color.argb(255, 87, 87, 87));

        float previewTextWidth = previewTextPaint.measureText(label);
//        float previewTextHeight = previewTextPaint.descent() - previewTextPaint.ascent();
        RectF previewRect = new RectF(0, 0, width, width);

        canvas.drawRoundRect(previewRect, 5 * mDensity, 5 * mDensity, previewPaint);
        canvas.drawText(label, (width - previewTextWidth)/2, previewRect.top - previewTextPaint.ascent(), previewTextPaint);

        super.onDraw(canvas);
    }

    public void setLabel(String label) {
        this.label = label;
        Log.e(TAG, "Label: " + label);

        this.invalidate();
    }
}

$(window).height();
$(window).width();

Using jQuery is not essential for getting those values, however. Use

document.documentElement.clientHeight;
document.documentElement.clientWidth;

to get sizes excluding scrollbars, or

window.innerHeight;
window.innerWidth;

to get the whole viewport, including scrollbars.

document.documentElement.clientHeight <= window.innerHeight;  // is always true

Fundamentally if you use it as part of a business then its commercial use - so its not a matter of whether the tools are directly generating income or not rather one of if they are being used in support of income generation directly or indirectly.

To take your specific example, if the purpose of the site is to sell or promote your paid services/product then its a commercial enterprise.

I have found that the best place is in NgAfterViewChecked(). I tried to execute code that would scroll to an ng-accordion panel when the page was loaded. I tried putting the code in NgAfterViewInit() but it did not work there (NPE). The problem was that the element had not been rendered yet. There is a problem with putting it in NgAfterViewChecked(). NgAfterViewChecked() is called several times as the page is rendered. Some calls are made before the element is rendered. This means a check for null may be required to guard the code from NPE. I am using Angular 8.

Have a look at SciPy cookbook. It should give you an idea of some basic methods to import /export data.

If you save/load the files from your own Python programs, you may also want to consider the Pickle module, or cPickle.

There may be two causes:

1. It is case-sensitive: DataFrame .... Dataframe, dataframe will not work.

2. You have not install pandas (pip install pandas) in the python path.

Just wanted to add some info that, we can check this info whether git pull automatically refers to any branch or not.

If you run the command, git remote show origin, (assuming origin as the short name for remote), git shows this info, whether any default reference exists for git pull or not.

Below is a sample output.(taken from git documentation).

$ git remote show origin
* remote origin
  Fetch URL: https://github.com/schacon/ticgit
  Push  URL: https://github.com/schacon/ticgit
  HEAD branch: master
  Remote branches:
    master                               tracked
    dev-branch                           tracked
  Local branch configured for 'git pull':
    master merges with remote master
  Local ref configured for 'git push':
    master pushes to master (up to date)

Please note the part where it shows, Local branch configured for git pull.

In this case, git pull will refer to git pull origin master

Initially, if you have cloned the repository, using git clone, these things are automatically taken care of. But if you have added a remote manually using git remote add, these are missing from the git config. If that is the case, then the part where it shows "Local branch configured for 'git pull':", would be missing from the output of git remote show origin.

The next steps to follow if no configuration exists for git pull, have already been explained by other answers.

margin: 0 -10px; 

is better than

margin: -10px;

The later sucks content vertically into it.

The file system of the container is in the data folder of docker, normally in /var/lib/docker. In order to start and inspect a running containers file system do the following:

hash=$(docker run busybox)
cd /var/lib/docker/aufs/mnt/$hash

And now the current working directory is the root of the container.

It wasn't working for me in all cases when I set

self.navigationItem.hidesBackButton = YES;

in viewWillAppear or ViewDidLoad, but worked perfectly when I set it in init of the viewController.

This isn't strictly an answer to your question about installing .gem packages, but you can specify all kinds of locations on a gem-by-gem basis by editing your Gemfile.

Specifying a :path attribute will install the gem from that path on your local machine.

gem "foreman", path: "/Users/pje/my_foreman_fork"

Alternately, specifying a :git attribute will install the gem from a remote git repository.

gem "foreman", git: "git://github.com/pje/foreman.git"

# ...or at a specific SHA-1 ref
gem "foreman", git: "git://github.com/pje/foreman.git", ref: "bf648a070c"

# ...or branch
gem "foreman", git: "git://github.com/pje/foreman.git", branch: "jruby"

# ...or tag
gem "foreman", git: "git://github.com/pje/foreman.git", tag: "v0.45.0"

(As @JHurrah mentioned in his comment.)

It's not an error. Javascript will gladly convert a number to a string when a string is expected (for example parseInt(42)), but in this case there is nothing that expect the number to be a string.

Here's a makeLowerCase function. :)

function makeLowerCase(value) {
  return value.toString().toLowerCase();
}

I got this error from my background service. I solved which creating a new scope.

                using (var scope = serviceProvider.CreateScope())
                {
                      // Process
                }

Edit AppServiceProvider.php will be found at app/Providers/AppServiceProvider.php and add

use Illuminate\Support\Facades\Schema;

public function boot()
{
Schema::defaultStringLength(191);
}

Then run

composer update

On your terminal. It helped me, may be it will work for you as well.

Preloading images using CSS only

In the below code I am randomly choosing the body element, since it is one of the only elements guaranteed to exist on the page.

For the "trick" to work, we shall use the content property which comfortably allows setting multiple URLs to be loaded, but as shown, the ::after pseudo element is kept hidden so the images won't be rendered:

body::after{
   position:absolute; width:0; height:0; overflow:hidden; z-index:-1; // hide images
   content:url(img1.png) url(img2.png) url(img3.gif) url(img4.jpg);   // load images
}

Demo

it's better to use a sprite image to reduce http requests...(if there are many relatively small sized images) and make sure the images are hosted where HTTP2 is used.

That syntax is a way of accessing a class member. PHP does not have pointers, but it does have references.

The syntax that you're quoting is basically the same as accessing a member from a pointer to a class in C++ (whereas dot notation is used when it isn't a pointer.)

The example in Javascript: The Good Parts can be adapted to do this:

var doubled_words = /([A-Za-z\u00C0-\u1FFF\u2800-\uFFFD]+)\s+\1(?:\s|$)/gi;

\b uses \w for word boundaries, where \w is equivalent to [0-9A-Z_a-z]. If you don't mind that limitation, the accepted answer is fine.

I was also getting this issue also however none of the above worked for me as I was using a custom binding (for BinaryXML) after an long time digging I found the answer here :-

Sending large XML from Silverlight to WCF

As am using a customBinding, the maxReceivedMessageSize has to be set on the httpTransport element under the binding element in the web.config:

<httpsTransport maxReceivedMessageSize="4194304" /> 

Also check out include-what-you-use, which solves a similar problem.

Similar to Scott McLeod's but this also generates a bash script to run the steps from the .travis.yml.

Troubleshooting Locally in Docker with a generated Bash script

# choose the image according to the language chosen in .travis.yml
$ docker run -it -u travis quay.io/travisci/travis-jvm /bin/bash

# now that you are in the docker image, switch to the travis user
sudo - travis

# Install a recent ruby (default is 1.9.3)
rvm install 2.3.0
rvm use 2.3.0

# Install travis-build to generate a .sh out of .travis.yml
cd builds
git clone https://github.com/travis-ci/travis-build.git
cd travis-build
gem install travis
# to create ~/.travis
travis version
ln -s `pwd` ~/.travis/travis-build
bundle install

# Create project dir, assuming your project is `AUTHOR/PROJECT` on GitHub
cd ~/builds
mkdir AUTHOR
cd AUTHOR
git clone https://github.com/AUTHOR/PROJECT.git
cd PROJECT
# change to the branch or commit you want to investigate
travis compile > ci.sh
# You most likely will need to edit ci.sh as it ignores matrix and env
bash ci.sh

The reason your attempt wasn't working, is because the two animations (fade-in and fade-out) were working against each other.

Right before an object became visible, it was still invisible and so the animation for fading-out would run. Then, the fraction of a second later when that same object had become visible, the fade-in animation would try to run, but the fade-out was still running. So they would work against each other and you would see nothing.

Eventually the object would become visible (most of the time), but it would take a while. And if you would scroll down by using the arrow-button at the button of the scrollbar, the animation would sort of work, because you would scroll using bigger increments, creating less scroll-events.

Enough explanation, the solution (JS, CSS, HTML):

$(window).on("load",function() {_x000D_
  $(window).scroll(function() {_x000D_
    var windowBottom = $(this).scrollTop() + $(this).innerHeight();_x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectBottom = $(this).offset().top + $(this).outerHeight();_x000D_
      _x000D_
      /* If the element is completely within bounds of the window, fade it in */_x000D_
      if (objectBottom < windowBottom) { //object comes into view (scrolling down)_x000D_
        if ($(this).css("opacity")==0) {$(this).fadeTo(500,1);}_x000D_
      } else { //object goes out of view (scrolling up)_x000D_
        if ($(this).css("opacity")==1) {$(this).fadeTo(500,0);}_x000D_
      }_x000D_
    });_x000D_
  }).scroll(); //invoke scroll-handler on page-load_x000D_
});

.fade {_x000D_
  margin: 50px;_x000D_
  padding: 50px;_x000D_
  background-color: lightgreen;_x000D_
  opacity: 1;_x000D_
}

• I wrapped the fade-codeline in an if-clause: if ($(this).css("opacity")==0) {...}. This makes sure the object is only faded in when the opacity is 0. Same goes for fading out. And this prevents the fade-in and fade-out from working against each other, because now there's ever only one of the two running at one time on an object.
• I changed .animate() to .fadeTo(). It's jQuery's specialized function for opacity, a lot shorter to write and probably lighter than animate.
• I changed .position() to .offset(). This always calculates relative to the body, whereas position is relative to the parent. For your case I believe offset is the way to go.
• I changed $(window).height() to $(window).innerHeight(). The latter is more reliable in my experience.
• Directly after the scroll-handler, I invoke that handler once on page-load with $(window).scroll();. Now you can give all desired objects on the page the .fade class, and objects that should be invisible at page-load, will be faded out immediately.
• I removed #container from both HTML and CSS, because (at least for this answer) it isn't necessary. (I thought maybe you needed the height:2000px because you used .position() instead of .offset(), otherwise I don't know. Feel free of course to leave it in your code.)

UPDATE

If you want opacity values other than 0 and 1, use the following code:

$(window).on("load",function() {_x000D_
  function fade(pageLoad) {_x000D_
    var windowBottom = $(window).scrollTop() + $(window).innerHeight();_x000D_
    var min = 0.3;_x000D_
    var max = 0.7;_x000D_
    var threshold = 0.01;_x000D_
    _x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectBottom = $(this).offset().top + $(this).outerHeight();_x000D_
      _x000D_
      /* If the element is completely within bounds of the window, fade it in */_x000D_
      if (objectBottom < windowBottom) { //object comes into view (scrolling down)_x000D_
        if ($(this).css("opacity")<=min+threshold || pageLoad) {$(this).fadeTo(500,max);}_x000D_
      } else { //object goes out of view (scrolling up)_x000D_
        if ($(this).css("opacity")>=max-threshold || pageLoad) {$(this).fadeTo(500,min);}_x000D_
      }_x000D_
    });_x000D_
  } fade(true); //fade elements on page-load_x000D_
  $(window).scroll(function(){fade(false);}); //fade elements on scroll_x000D_
});

.fade {_x000D_
  margin: 50px;_x000D_

  background-color: lightgreen;_x000D_
  opacity: 1;_x000D_

• I added a threshold to the if-clause, see explanation below.
• I created variables for the threshold and for min/max at the start of the function. In the rest of the function these variables are referenced. This way, if you ever want to change the values again, you only have to do it in one place.
• I also added || pageLoad to the if-clause. This was necessary to make sure all objects are faded to the correct opacity on page-load. pageLoad is a boolean that is send along as an argument when fade() is invoked.
  I had to put the fade-code inside the extra function fade() {...}, in order to be able to send along the pageLoad boolean when the scroll-handler is invoked.
  I did't see any other way to do this, if anyone else does, please leave a comment.

Explanation:
The reason the code in your fiddle didn't work, is because the actual opacity values are always a little off from the value you set it to. So if you set the opacity to 0.3, the actual value (in this case) is 0.300000011920929. That's just one of those little bugs you have to learn along the way by trail and error. That's why this if-clause won't work: if ($(this).css("opacity") == 0.3) {...}.

I added a threshold, to take that difference into account: == 0.3 becomes <= 0.31.
(I've set the threshold to 0.01, this can be changed of course, just as long as the actual opacity will fall between the set value and this threshold.)

The operators are now changed from == to <= and >=.

UPDATE 2:

If you want to fade the elements based on their visible percentage, use the following code:

$(window).on("load",function() {_x000D_
  function fade(pageLoad) {_x000D_
    var windowTop=$(window).scrollTop(), windowBottom=windowTop+$(window).innerHeight();_x000D_
    var min=0.3, max=0.7, threshold=0.01;_x000D_
    _x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectHeight=$(this).outerHeight(), objectTop=$(this).offset().top, objectBottom=$(this).offset().top+objectHeight;_x000D_
      _x000D_
      /* Fade element in/out based on its visible percentage */_x000D_
      if (objectTop < windowTop) {_x000D_
        if (objectBottom > windowTop) {$(this).fadeTo(0,min+((max-min)*((objectBottom-windowTop)/objectHeight)));}_x000D_
        else if ($(this).css("opacity")>=min+threshold || pageLoad) {$(this).fadeTo(0,min);}_x000D_
      } else if (objectBottom > windowBottom) {_x000D_
        if (objectTop < windowBottom) {$(this).fadeTo(0,min+((max-min)*((windowBottom-objectTop)/objectHeight)));}_x000D_
        else if ($(this).css("opacity")>=min+threshold || pageLoad) {$(this).fadeTo(0,min);}_x000D_
      } else if ($(this).css("opacity")<=max-threshold || pageLoad) {$(this).fadeTo(0,max);}_x000D_
    });_x000D_
  } fade(true); //fade elements on page-load_x000D_
  $(window).scroll(function(){fade(false);}); //fade elements on scroll_x000D_
});

.fade {_x000D_
  margin: 50px;_x000D_
  padding: 50px;_x000D_
  background-color: lightgreen;_x000D_

You can use your own custom fonts by setting the font path using pygame.font.Font

pygame.font.Font(filename, size): return Font

example:

pygame.font.init()
font_path = "./fonts/newfont.ttf"
font_size = 32
fontObj = pygame.font.Font(font_path, font_size)

Then render the font using fontObj.render and blit to a surface as in veiset's answer above. :)

If you run npm config edit, you'll get an editor showing the current configuration, and also a list of options and their default values.

But I don't think there's a 'reset' command.

This is what I had to do:

1. Install the latest Android SDK Manager (22.0.1)
2. Install Gradle (1.6)
3. Update my environment variables:
   • ANDROID_HOME=C:\...\android-sdk
   • GRADLE_HOME=C:\...\gradle-1.6
4. Update/dobblecheck my PATH variable:
   • PATH=...;%GRADLE_HOME%\bin;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools
5. Start Android SDK Manager and download necessary SDK API's

I resolved it with the next:

In build.gradle you need to add the next one.

android {
...
   defaultConfig {
       ...
       // Enabling multidex support.
       multiDexEnabled true
       ...
   }
   dexOptions {
      incremental true
      maxProcessCount 4 // this is the default value
      javaMaxHeapSize "2g"
   }
...
}
dependencies {
...
   compile 'com.android.support:multidex:1.0.1'
...
}

Add the next one in local.properties

org.gradle.parallel=true
org.gradle.configureondemand=true
org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

After that into Application class you need to add the Multidex too.

 public class MyApplication extends MultiDexApplication {

   @Override
   public void onCreate() {
       super.onCreate();
       //mas codigo
   }

   @Override
   protected void attachBaseContext(Context base) {
       super.attachBaseContext(base);
       MultiDex.install(this);
   }
}

Don't forget add the line code into Manifest.xml

<application
    ...
    android:name=".MyApplication"
    ...
/>

That's it with this was enough for resolve the bug: Execution failed for task ':app:transformClassesWithDexForDebug. Check very well into build.gradle with javaMaxHeapSize "2g" and the local.properties org.gradle.jvmargs=-Xmx2048m are of 2 gigabyte.

If you are binding to the onclick event, it might be slow on touch screens.

To make it faster, I use fastclick, which uses the much faster touch events to mimic the click event.

I had the same issue. I am currently using Asp.net Core 2.2. I solved this problem with the following piece of code.

using Microsoft.AspNetCore.Identity;
var user = await _userManager.FindByEmailAsync(User.Identity.Name);

I hope this will be useful to someone.

When you include a string literal in a query, you can enclose the string in either single or double quotes; Access' database engine will accept either. So double quotes will avoid the problem with a string which contains a single quote.

SELECT * FROM tblStudents WHERE [name] Like "Daniel O'Neal";

If you want to keep the single quotes around your string, you can double up the single quote within it, as mentioned in other answers.

SELECT * FROM tblStudents WHERE [name] Like 'Daniel O''Neal';

Notice the square brackets surrounding name. I used the brackets to lessen the chance of confusing the database engine because name is a reserved word.

It's not clear why you're using the Like comparison in your query. Based on what you've shown, this should work instead.

SELECT * FROM tblStudents WHERE [name] = "Daniel O'Neal";

_{Note: This is not a duplicate, because the OP is aware that the image from cv2.imread is in BGR format (unlike the suggested duplicate question that assumed it was RGB hence the provided answers only address that issue)}

To illustrate, I've opened up this same color JPEG image:

once using the conversion

img = cv2.imread(path)
img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

and another by loading it in gray scale mode

img_gray_mode = cv2.imread(path, cv2.IMREAD_GRAYSCALE)

Like you've documented, the diff between the two images is not perfectly 0, I can see diff pixels in towards the left and the bottom

I've summed up the diff too to see

import numpy as np
np.sum(diff)
# I got 6143, on a 494 x 750 image

I tried all cv2.imread() modes

Among all the IMREAD_ modes for cv2.imread(), only IMREAD_COLOR and IMREAD_ANYCOLOR can be converted using COLOR_BGR2GRAY, and both of them gave me the same diff against the image opened in IMREAD_GRAYSCALE

The difference doesn't seem that big. My guess is comes from the differences in the numeric calculations in the two methods (loading grayscale vs conversion to grayscale)

Naturally what you want to avoid is fine tuning your code on a particular version of the image just to find out it was suboptimal for images coming from a different source.

In brief, let's not mix the versions and types in the processing pipeline.

So I'd keep the image sources homogenous, e.g. if you have capturing the image from a video camera in BGR, then I'd use BGR as the source, and do the BGR to grayscale conversion cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

Vice versa if my ultimate source is grayscale then I'd open the files and the video capture in gray scale cv2.imread(path, cv2.IMREAD_GRAYSCALE)

You can use this method to draw polyline on googleMap

// Draw polyline on map
public void drawPolyLineOnMap(List<LatLng> list) {
    PolylineOptions polyOptions = new PolylineOptions();
    polyOptions.color(Color.RED);
    polyOptions.width(5);
    polyOptions.addAll(list);

    googleMap.clear();
    googleMap.addPolyline(polyOptions);

    LatLngBounds.Builder builder = new LatLngBounds.Builder();
    for (LatLng latLng : list) {
        builder.include(latLng);
    }

    final LatLngBounds bounds = builder.build();

    //BOUND_PADDING is an int to specify padding of bound.. try 100.
    CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, BOUND_PADDING);
    googleMap.animateCamera(cu);
}

You need to add this line in your gradle in case you haven't.

compile 'com.google.android.gms:play-services-maps:8.4.0'

Here it is in one line, without having to retype any of the variables or their values:

fruitdict.update({k:v for k,v in locals().copy().iteritems() if k[:2] != '__' and k != 'fruitdict'})

Java supports two methods for XML parsing out of the box.

SAXParser

You can use this parser if you want to parse large XML files and/or don't want to use a lot of memory.

http://download.oracle.com/javase/6/docs/api/javax/xml/parsers/SAXParserFactory.html

Example: http://www.mkyong.com/java/how-to-read-xml-file-in-java-sax-parser/

DOMParser

You can use this parser if you need to do XPath queries or need to have the complete DOM available.

http://download.oracle.com/javase/6/docs/api/javax/xml/parsers/DocumentBuilderFactory.html

Example: http://www.mkyong.com/java/how-to-read-xml-file-in-java-dom-parser/

Unfortunately, that's what borders do, they're counted as part of the space an element takes up. Allow me to introduce border's less commonly known cousin: outline. It is virtually identical to border. Only difference is that it behaves more like box-shadow in that it doesn't take up space in your layout and it has to be on all 4 sides of the element.

http://codepen.io/cimmanon/pen/wyktr

.foo {
    outline: 1px solid orange;
}

My answer does 100% fit to this problem, but I want to document my solution and the trap behind it, since the Exception is the same.

My port was always in use testing a Jetty in a Junit testcase. Problem was Google's code pro on Eclipse, which, I guess, was testing in the background and thus starting jetty before me all the time. Workaround: let Eclipse open *.java files always w/ the Java editor instead of Google's Junit editor. That seems to help.

What you are trying to do can be simplified down to this.

$('input:text').bind('focus blur', function() {_x000D_
    $(this).toggleClass('red');_x000D_
});

input{_x000D_
    background:#FFFFEE;_x000D_
}_x000D_
.red{_x000D_
    background-color:red;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<form>_x000D_
    <input class="calc_input" type="text" name="start_date" id="start_date" />_x000D_
    <input class="calc_input" type="text" name="end_date" id="end_date" />_x000D_
    <input class="calc_input" size="8" type="text" name="leap_year" id="leap_year" />_x000D_
</form>

You use an addtional attribute; fill-opacity: This attribute takes a decimal number between 0.0 and 1.0, inclusive; where 0.0 is completely transparent.

For example:

<rect ... fill="#044B94" fill-opacity="0.4"/>

Additionally you have the following:

• stroke-opacity attribute for the stroke
• opacity for the entire object

Simply do this:

<?php

array_push($array, '');
$array = array_reverse($array);
array_shift($array);

The below PL/SQL block finds all locked rows in a table. The other answers only find the blocking session, finding the actual locked rows requires reading and testing each row.

(However, you probably do not need to run this code. If you're having a locking problem, it's usually easier to find the culprit using GV$SESSION.BLOCKING_SESSION and other related data dictionary views. Please try another approach before you run this abysmally slow code.)

First, let's create a sample table and some data. Run this in session #1.

--Sample schema.
create table test_locking(a number);
insert into test_locking values(1);
insert into test_locking values(2);
commit;
update test_locking set a = a+1 where a = 1;

In session #2, create a table to hold the locked ROWIDs.

--Create table to hold locked ROWIDs.
create table locked_rowids(the_rowid rowid);
--Remove old rows if table is already created:
--delete from locked_rowids;
--commit;

In session #2, run this PL/SQL block to read the entire table, probe each row, and store the locked ROWIDs. Be warned, this may be ridiculously slow. In your real version of this query, change both references to TEST_LOCKING to your own table.

--Save all locked ROWIDs from a table.
--WARNING: This PL/SQL block will be slow and will temporarily lock rows.
--You probably don't need this information - it's usually good enough to know
--what other sessions are locking a statement, which you can find in
--GV$SESSION.BLOCKING_SESSION.
declare
    v_resource_busy exception;
    pragma exception_init(v_resource_busy, -00054);
    v_throwaway number;
    type rowid_nt is table of rowid;
    v_rowids rowid_nt := rowid_nt();
begin
    --Loop through all the rows in the table.
    for all_rows in
    (
        select rowid
        from test_locking
    ) loop
        --Try to look each row.
        begin
            select 1
            into v_throwaway
            from test_locking
            where rowid = all_rows.rowid
            for update nowait;
        --If it doesn't lock, then record the ROWID.
        exception when v_resource_busy then
            v_rowids.extend;
            v_rowids(v_rowids.count) := all_rows.rowid;
        end;

        rollback;
    end loop;

    --Display count:
    dbms_output.put_line('Rows locked: '||v_rowids.count);

    --Save all the ROWIDs.
    --(Row-by-row because ROWID type is weird and doesn't work in types.)
    for i in 1 .. v_rowids.count loop
        insert into locked_rowids values(v_rowids(i));
    end loop;
    commit;
end;
/

Finally, we can view the locked rows by joining to the LOCKED_ROWIDS table.

--Display locked rows.
select *
from test_locking
where rowid in (select the_rowid from locked_rowids);

An alternative answer that uses today() method to calculate current date and then subtracts one using timedelta(). Rest of the steps remain the same.

https://docs.python.org/3.7/library/datetime.html#timedelta-objects

from datetime import date, timedelta
today = date.today()
yesterday = today - timedelta(days = 1)
print(today)
print(yesterday)

Output: 
2019-06-14
2019-06-13

Perhaps something like this?

<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
 <!-- general application log -->
 <appender name="MainLogFile" class="org.apache.log4j.FileAppender">

  <appender-ref ref="FooLogFile"/>
 </logger>
 <!-- default logging -->

  <appender-ref ref="MainLogFile"/>
 </root>
</log4j:configuration>

Thus, all info messages are written to server.log; by contrast, foo.log contains only com.example.foo messages, including debug-level messages.

If your constructor is similar to this one:

public Example(String example) {
    if (example == null) {
        throw new NullPointerException();
    }
    //do fun things with valid example here
}

Then, when you run this JUnit test you will get a green bar:

@Test(expected = NullPointerException.class)
public void constructorShouldThrowNullPointerException() {
    Example example = new Example(null);
}

Marshaling and serialization are loosely synonymous in the context of remote procedure call, but semantically different as a matter of intent.

In particular, marshaling is about getting parameters from here to there, while serialization is about copying structured data to or from a primitive form such as a byte stream. In this sense, serialization is one means to perform marshaling, usually implementing pass-by-value semantics.

It is also possible for an object to be marshaled by reference, in which case the data "on the wire" is simply location information for the original object. However, such an object may still be amenable to value serialization.

As @Bill mentions, there may be additional metadata such as code base location or even object implementation code.

It's a wchar_t literal, for extended character set. Wikipedia has a little discussion on this topic, and c++ examples.

Yes, the first one is a static method also called class method, while the second one is an instance method.

Consider the following examples, to understand it in more detail.

In ES5

function Person(firstName, lastName) {
   this.firstName = firstName;
   this.lastName = lastName;
}

Person.isPerson = function(obj) {
   return obj.constructor === Person;
}

Person.prototype.sayHi = function() {
   return "Hi " + this.firstName;
}

In the above code, isPerson is a static method, while sayHi is an instance method of Person.

Below, is how to create an object from Person constructor.

var aminu = new Person("Aminu", "Abubakar");

Using the static method isPerson.

Person.isPerson(aminu); // will return true

Using the instance method sayHi.

aminu.sayHi(); // will return "Hi Aminu"

In ES6

class Person {
   constructor(firstName, lastName) {
      this.firstName = firstName;
      this.lastName = lastName;
   }

   static isPerson(obj) {
      return obj.constructor === Person;
   }

   sayHi() {
      return `Hi ${this.firstName}`;
   }
}

Look at how static keyword was used to declare the static method isPerson.

To create an object of Person class.

const aminu = new Person("Aminu", "Abubakar");

Using the static method isPerson.

Person.isPerson(aminu); // will return true

Using the instance method sayHi.

aminu.sayHi(); // will return "Hi Aminu"

NOTE: Both examples are essentially the same, JavaScript remains a classless language. The class introduced in ES6 is primarily a syntactical sugar over the existing prototype-based inheritance model.

.subscribe is not an Angular2 thing.

It's a method that comes from rxjs library which Angular is using internally.

If you can imagine yourself subscribing to a newsletter, every time there is a new newsletter, they will send it to your home (the method inside subscribe gets called).

That's what happens when you subscribing to a source of magazines ( which is called an Observable in rxjs library)

All the AJAX calls in Angular are using rxjs internally and in order to use any of them, you've got to use the method name, e.g get, and then call subscribe on it, because get returns and Observable.

Also, when writing this code <button (click)="doSomething()">, Angular is using Observables internally and subscribes you to that source of event, which in this case is a click event.

Back to our analogy of Observables and newsletter stores, after you've subscribed, as soon as and as long as there is a new magazine, they'll send it to you unless you go and unsubscribe from them for which you have to remember the subscription number or id, which in rxjs case it would be like :

 let subscription = magazineStore.getMagazines().subscribe(
   (newMagazine)=>{

         console.log('newMagazine',newMagazine);

    }); 

And when you don't want to get the magazines anymore:

   subscription.unsubscribe();

Also, the same goes for

 this.route.paramMap

which is returning an Observable and then you're subscribing to it.

My personal view is rxjs was one of the greatest things that were brought to JavaScript world and it's even better in Angular.

There are 150~ rxjs methods ( very similar to lodash methods) and the one that you're using is called switchMap

Warning

If you run PowerShell from a cmd.exe window created by Powershell, the 2nd instance no longer waits for jobs to complete.

cmd>  PowerShell
PS> Start-Process cmd.exe -Wait 

Now from the new cmd window, run PowerShell again and within it start a 2nd cmd window: cmd2> PowerShell

PS> Start-Process cmd.exe -Wait
PS>   

The 2nd instance of PowerShell no longer honors the -Wait request and ALL background process/jobs return 'Completed' status even thou they are still running !

I discovered this when my C# Explorer program is used to open a cmd.exe window and PS is run from that window, it also ignores the -Wait request. It appears that any PowerShell which is a 'win32 job' of cmd.exe fails to honor the wait request.

I ran into this with PowerShell version 3.0 on windows 7/x64

Here is another variant I found that produced completely different results from the grep search for [\x80-\xFF] in the accepted answer. Perhaps it will be useful to someone to find additional non-ascii characters:

grep --color='auto' -P -n "[^[:ascii:]]" myfile.txt

Note: my computer's grep (a Mac) did not have -P option, so I did brew install grep and started the call above with ggrep instead of grep.

Right_click on the drawable and create new layout xml file in the name of for example button_background.xml. then copy and paste the following code. You can change it according your need.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="14dp" />
<solid android:color="@color/colorButton" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
<size
android:width="120dp"
android:height="40dp" />
</shape>

Now you can use it.

<Button
android:background="@drawable/button_background"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

on MAC starting from chrome Version 67.0.3396.99 my self-signed certificate stopped to work.

had a chance to confirm that my approach works today :). If it doesn't work for you make sure your are using this approach

copied from here https://ksearch.wordpress.com/2017/08/22/generate-and-import-a-self-signed-ssl-certificate-on-mac-osx-sierra/

END UPDATE

finally was able to see green Secure only when removed my cert from system, and added it to local keychain. (if there is one - drop it first). Not sure if it maters but in my case I downloaded certificate via chrome, and verified that create date is today - so it is the one I've just created.

hope it will be helpful for someone spend like a day on it.

never update chrome!

recursion + memorization could lead to a more efficient solution compare with a pure iterative approach, e.g. check this: http://jsperf.com/fibonacci-memoized-vs-iterative-for-large-n

My solution was the following:

document.getElementById("agent_details").scrollIntoView();

If executed within "sqlplus", you can execute a host operating system command "sleep" :

!sleep 1

or

host sleep 1

This works for me.

<select formControlName="preferredBankAccountId" class="form-control" value="">
    <option value="">Please select</option>    
    <option *ngFor="let item of societyAccountDtos" [value]="item.societyAccountId" >{{item.nickName}}</option>
</select>

Not sure this is valid or not, correct me if it's wrong.
Correct me if this should not be like this.

Passing null would be better. The full codes is like:

WebView wv = (WebView)this.findViewById(R.id.myWebView);
wv.getSettings().setJavaScriptEnabled(true);
wv.loadDataWithBaseURL(null, "<html>...</html>", "text/html", "utf-8", null);

It's not necessary to rewrite everything. I recommend doing this instead:

Post this inside your .m file of your custom cell.

- (void)layoutSubviews {
    [super layoutSubviews];
    self.imageView.frame = CGRectMake(0,0,32,32);
}

This should do the trick nicely. :]

All the answers so far don't address the trailing concern:

Is there an efficient method when there are hundreds of revisions after the one to be deleted?

The steps follow, but for reference, let's assume the following history:

[master] -> [hundreds-of-commits-including-merges] -> [C] -> [R] -> [B]

C: commit just following the commit to be removed (clean)

R: The commit to be removed

B: commit just preceding the commit to be removed (base)

Because of the "hundreds of revisions" constraint, I'm assuming the following pre-conditions:

1. there is some embarrassing commit that you wish never existed
2. there are ZERO subsequent commits that actually depend on that embarassing commit (zero conflicts on revert)
3. you don't care that you will be listed as the 'Committer' of the hundreds of intervening commits ('Author' will be preserved)
4. you have never shared the repository
   • or you actually have enough influence over all the people who have ever cloned history with that commit in it to convince them to use your new history
   • and you don't care about rewriting history

This is a pretty restrictive set of constraints, but there is an interesting answer that actually works in this corner case.

Here are the steps:

1. git branch base B
2. git branch remove-me R
3. git branch save
4. git rebase --preserve-merges --onto base remove-me

If there are truly no conflicts, then this should proceed with no further interruptions. If there are conflicts, you can resolve them and rebase --continue or decide to just live with the embarrassment and rebase --abort.

Now you should be on master that no longer has commit R in it. The save branch points to where you were before, in case you want to reconcile.

How you want to arrange everyone else's transfer over to your new history is up to you. You will need to be acquainted with stash, reset --hard, and cherry-pick. And you can delete the base, remove-me, and save branches

puts call the to_s of each argument and adds a new line to each string, if it does not end with new line. print just output each argument by calling their to_s.

for example: puts "one two": one two

{new line}

puts "one two\n": one two

{new line} #puts will not add a new line to the result, since the string ends with a new line

print "one two": one two

print "one two\n": one two

{new line}

And there is another way to output: p

For each object, directly writes obj.inspect followed by a newline to the program’s standard output.

It is helpful to output debugging message. p "aa\n\t": aa\n\t

Another interesting part of usage of readonly marking can be protecting field from initialization in singleton.

        new Lazy<Singleton>(() => new Singleton());

    public static Singleton Instance { get { return lazy.Value; } }

    private Singleton()
    {
    }
}

readonly plays small role of protecting field Singleton from being initialized twice. Another detail is that for mentioned scenario you can't use const because const forces creation during compile time, but singleton makes creation at run time.

You could make it absolute and put zeros to top and bottom that is:

#fullHeightDiv {
    position: absolute;
    top: 0;
    bottom: 0;
}

Simple and neet : use vw units for a responsive height/width according to the viewport width.

vw : 1/100th of the width of the viewport. (Source MDN)

DEMO

HTML:

<div></div>

CSS for a 1:1 aspect ratio:

div{
    width:80vw;
    height:80vw; /* same as width */
}

Table to calculate height according to the desired aspect ratio and width of element.

   aspect ratio  |  multiply width by
    -----------------------------------
         1:1      |         1
         1:3      |         3
         4:3      |        0.75
        16:9      |       0.5625

This technique allows you to :

• insert any content inside the element without using position:absolute;
• no unecessary HTML markup (only one element)
• adapt the elements aspect ratio according to the height of the viewport using vh units
• you can make a responsive square or other aspect ratio that alway fits in viewport according to the height and width of the viewport (see this answer : Responsive square according to width and height of viewport or this demo)

These units are supported by IE9+ see canIuse for more info

The problem with singletons is not their implementation. It is that they conflate two different concepts, neither of which is obviously desirable.

1) Singletons provide a global access mechanism to an object. Although they might be marginally more threadsafe or marginally more reliable in languages without a well-defined initialization order, this usage is still the moral equivalent of a global variable. It's a global variable dressed up in some awkward syntax (foo::get_instance() instead of g_foo, say), but it serves the exact same purpose (a single object accessible across the entire program) and has the exact same drawbacks.

2) Singletons prevent multiple instantiations of a class. It's rare, IME, that this kind of feature should be baked into a class. It's normally a much more contextual thing; a lot of the things that are regarded as one-and-only-one are really just happens-to-be-only-one. IMO a more appropriate solution is to just create only one instance--until you realize that you need more than one instance.

As noted in the previous answers somewhere the window.innerHeight variable gets updated properly now on iOS10 when the keyboard appears and since I don't need the support for earlier versions I came up with the following hack that might be a bit easier then the discussed "solutions".

//keep track of the "expected" height
var windowExpectedSize = window.innerHeight;

//update expected height on orientation change
window.addEventListener('orientationchange', function(){
    //in case the virtual keyboard is open we close it first by removing focus from the input elements to get the proper "expected" size
    if (window.innerHeight != windowExpectedSize){
        $("input").blur();
        $("div[contentEditable]").blur();     //you might need to add more editables here or you can focus something else and blur it to be sure
        setTimeout(function(){
            windowExpectedSize = window.innerHeight;
        },100);
    }else{
        windowExpectedSize = window.innerHeight;
    }
});

//and update the "expected" height on screen resize - funny thing is that this is still not triggered on iOS when the keyboard appears
window.addEventListener('resize', function(){
    $("input").blur();  //as before you can add more blurs here or focus-blur something
    windowExpectedSize = window.innerHeight;
});

then you can use:

if (window.innerHeight != windowExpectedSize){ ... }

to check if the keyboard is visible. I've been using it for a while now in my web app and it works well, but (as all of the other solutions) you might find a situation where it fails because the "expected" size is not updated properly or something.

It's example from great MSDN article about using ExpandoObject for creating dynamic ad-hoc types for incoming structured data (i.e XML, Json).

We can also assign delegate to ExpandoObject's dynamic property:

dynamic person = new ExpandoObject();
person.FirstName = "Dino";
person.LastName = "Esposito";

person.GetFullName = (Func<String>)(() => { 
  return String.Format("{0}, {1}", 
    person.LastName, person.FirstName); 
});

var name = person.GetFullName();
Console.WriteLine(name);

Thus it allows us to inject some logic into dynamic object at runtime. Therefore, together with lambda expressions, closures, dynamic keyword and DynamicObject class, we can introduce some elements of functional programming into our C# code, which we knows from dynamic languages as like JavaScript or PHP.

$name = str_replace(' ', '_', $name);

http://php.net/manual/en/function.str-replace.php

the bottom cell will grow as you enter more text ... setting the table width will help too

To rollback the last migration you can do:

rake db:rollback

If you want to rollback a specific migration with a version you should do:

rake db:migrate:down VERSION=YOUR_MIGRATION_VERSION

If the migration file you want to rollback was called db/migrate/20141201122027_create_some_table.rb, then the VERSION for that migration is 20141201122027, which is the timestamp of when that migration was created, and the command to roll back that migration would be:

rake db:migrate:down VERSION=20141201122027

You most probably don't need z-index to do that. You can use relative and absolute positioning.

I advise you to take a better look at css positioning and the difference between relative and absolute positioning... I saw you're setting position: absolute; to an element and trying to float that element. It won't work friend! When you understand positioning in CSS it will make your work a lot easier! ;)

Edit: Just to be clear, positioning is not a replacement for them and I do use z-index. I just try to avoid using them. Using z-indexes everywhere seems easy and fun at first... until you have bugs related to them and find yourself having to revisit and manage z-indexes.

In case of array like

result = [ '2015',  '2014',  '2013',  '2011' ],

it gets tricky if you are using escape sequence like:

result = [ \'2015\',  \'2014\',  \'2013\',  \'2011\' ].

Instead, good way to do it is to wrap the array with single quotes as follows:

result = "'"+result+"'";

I to had a similar doubt what I got to know was getActivity() returns the Activity to which the fragment is associated.

The getActivity() method is used generally in static fragment as the associated activity will not be static and non static member cannot be used in static member.

Rand does not get you a random number. It gives you the next number in a sequence generated by a pseudorandom number generator. To get a different sequence every time you start your program, you have to seed the algorithm by calling srand.

A (very bad) way to do it is by passing it the current time:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main() {
    srand(time(NULL));
    int i, j = 0;
    for(i = 0; i <= 10; i++) {
        j = rand();
        printf("j = %d\n", j);
    }
    return 0;
}

Why this is a bad way? Because a pseudorandom number generator is as good as its seed, and the seed must be unpredictable. That is why you may need a better source of entropy, like reading from /dev/urandom.

If you are still struggling to find an answer, specially if you produced a file for the output, and you prefer a clear alternative: echo "hi" | grep "use this hack to hide the oputut :) "

This is how I do it...

public class ThreadA {
    public ThreadA(object[] args) {
        ...
    }
    public void Run() {
        while (true) {
            Thread.sleep(1000); // wait 1 second for something to happen.
            doStuff();
            if(conditionToExitReceived) // what im waiting for...
                break;
        }
        //perform cleanup if there is any...
    }
}

Then to run this in its own thread... ( I do it this way because I also want to send args to the thread)

private void FireThread(){
    Thread thread = new Thread(new ThreadStart(this.startThread));
    thread.start();
}
private void (startThread){
    new ThreadA(args).Run();
}

The thread is created by calling "FireThread()"

The newly created thread will run until its condition to stop is met, then it dies...

You can signal the "main" with delegates, to tell it when the thread has died.. so you can then start the second one...

You're asking it to parse the JSON text something (not "something"). That's invalid JSON, strings must be in double quotes.

If you want an equivalent to your first example:

var s = '"something"';
var result = JSON.parse(s);

Here is the compressive in detailed explanation with the help of above posts:

1. Math.trunc() : It is used to remove those digits which are followed by dot. It converts implicitly. But, not supported in IE.

Example:

Math.trunc(10.5) // 10

Math.trunc(-10.5) // -10

Other Alternative way: Use of bitwise not operator:

Example:

x= 5.5

~~x // 5

2. Math.floor() : It is used to give the minimum integer value posiible. It is supported in all browsers.

Example:

Math.floor(10.5) // 10

Math.floor( -10.5) // -11

3. Math.ceil() : It is used to give the highest integer value possible. It is supported in all browsers.

Example:

Math.ceil(10.5) // 11

Math.ceil(-10.5) // -10

4. Math.round() : It is rounded to the nearest integer. It is supported in all browsers.

Example:

Math.round(10.5) // 11

Math.round(-10.5)// -10

Math.round(10.49) // 10

Math.round(-10.51) // -11

You should use DateTime.TryParseExcact if you know the format, or if not and want to use the system settings DateTime.TryParse. And to print the date,DateTime.ToString with the right format in the argument. To get the year, month or day you have DateTime.Year, DateTime.Month or DateTime.Day.

See DateTime Structures in MSDN for additional references.

I had the same issue just add this function to the open dialog options and it worked sharm

open: function(){
            var closeBtn = $('.ui-dialog-titlebar-close');
            closeBtn.append('<span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span>');
        },

and on close event you need to remove that

close: function () {
            var closeBtn = $('.ui-dialog-titlebar-close');
            closeBtn.html('');}

Complete example

<div id="deleteDialog" title="Confirm Delete">
 Can you confirm you want to delete this event?
</div> 

$("#deleteDialog").dialog({
                width: 400, height: 200,
                modal: true,
                open: function () {
                    var closeBtn = $('.ui-dialog-titlebar-close');
                    closeBtn.append('<span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span>');
                },
                close: function () {
                    var closeBtn = $('.ui-dialog-titlebar-close');
                    closeBtn.html('');
                },
                buttons: {
                    "Confirm": function () {
                        calendar.fullCalendar('removeEvents', event._id);
                        $(this).dialog("close");
                    },
                    "Cancel": function () {
                        $(this).dialog("close");
                    }
                }
            });

            $("#dialog").dialog("open");

There may be 2 spaces after the text, please confirm. You can use LTRIM and RTRIM functions also right?

LTRIM(RTRIM(ProductAlternateKey))

Maybe the extra space isn't ordinary spaces (ASCII 32, soft space)? Maybe they are "hard space", ASCII 160?

ltrim(rtrim(replace(ProductAlternateKey, char(160), char(32))))

Yes! Any class in Java can have multiple main methods. It's called Overloading (Overloaded methods are methods with same name but with different signatures) but there should only be one main method with parameters like this :- (String[] args) or (String args[])

For example :-public class E {

public static void main(String args){
    System.out.println("Print A");
}
public static void main(String [] args){
    System.out.println("Print B");
}
public static void main(int garbage){
    System.out.println("Print C");
}
public static void main(int i){
    System.out.println("Print D")
}

}

The output of the above program will be "Print B" as only that main method contains the correct method signature identified by the Javac compiler and it compiles that only and leaves the rest.

If x is an 8 bit value, you can use this:

x=(x>>1 | x<<7);

Here's another solution using the bin_data() function from the mltools package.

library(mltools)

# Resulting bins have an equal number of observations in each group
das[, "wt2"] <- bin_data(das$wt, bins=3, binType = "quantile")

# Resulting bins are equally spaced from min to max
das[, "wt3"] <- bin_data(das$wt, bins=3, binType = "explicit")

# Or if you'd rather define the bins yourself
das[, "wt4"] <- bin_data(das$wt, bins=c(-Inf, 250, 322, Inf), binType = "explicit")

das
   anim    wt                                  wt2                                  wt3         wt4

You're trying to compile an image.

Type out what you've hand written into a document called main.cpp, run that file through your compiler, then run the output file.

Use this:

var memoryStream = new MemoryStream();
stream.CopyTo(memoryStream);

This will convert Stream to MemoryStream.

for me changing the Mysql character encoding the same as my code helped to sort out the solution. `photo=open('pic3.png',encoding=latin1), strong text

To Remove Special character

String t2 = "!@#$%^&*()-';,./?><+abdd";

t2 = t2.replaceAll("\\W+","");

Output will be : abdd.

This works perfectly.

I was getting the same issue with a different application,

Faulting application name: javaw.exe, version: 8.0.51.16, time stamp: 0x55763d32
Faulting module name: mscorwks.dll, version: 2.0.50727.5485, time stamp: 0x53a11d6c
Exception code: 0xc0000005
Fault offset: 0x0000000000501090
Faulting process id: 0x2960
Faulting application start time: 0x01d0c39a93c695f2
Faulting application path: C:\Program Files\Java\jre1.8.0_51\bin\javaw.exe
Faulting module path:C:\Windows\Microsoft.NET\Framework64\v2.0.50727\mscorwks.dll

I was using the The Enhanced Mitigation Experience Toolkit (EMET) from Microsoft and I found by disabling the EMET features on javaw.exe in my case as this was the faulting application, it enabled my application to run successfully. Make sure you don't have any similar software with security protections on memory.

As of 3.3, time.clock() is deprecated, and it's suggested to use time.process_time() or time.perf_counter() instead.

Previously in 2.7, according to the time module docs:

time.clock()

On Unix, return the current processor time as a floating point number expressed in seconds. The precision, and in fact the very definition of the meaning of “processor time”, depends on that of the C function of the same name, but in any case, this is the function to use for benchmarking Python or timing algorithms.

On Windows, this function returns wall-clock seconds elapsed since the first call to this function, as a floating point number, based on the Win32 function QueryPerformanceCounter(). The resolution is typically better than one microsecond.

Additionally, there is the timeit module for benchmarking code snippets.

This has really puzzled me for a while but this is what I found in the end.

When you call, sc.close() in first method, it not only closes your scanner but closes your System.in input stream as well. You can verify it by printing its status at very top of the second method as :

    System.out.println(System.in.available());

So, now when you re-instantiate, Scanner in second method, it doesn't find any open System.in stream and hence the exception.

I doubt if there is any way out to reopen System.in because:

public void close() throws IOException --> Closes this input stream and releases any system resources associated with this stream. The general contract of close is that it closes the input stream. A closed stream cannot perform input operations and **cannot be reopened.**

The only good solution for your problem is to initiate the Scanner in your main method, pass that as argument in your two methods, and close it again in your main method e.g.:

main method related code block:

Scanner scanner = new Scanner(System.in);  

// Ask users for quantities 
PromptCustomerQty(customer, ProductList, scanner );

// Ask user for payment method
PromptCustomerPayment(customer, scanner );

//close the scanner 
scanner.close();

Your Methods:

 public static void PromptCustomerQty(Customer customer, 
                             ArrayList<Product> ProductList, Scanner scanner) {

    // no more scanner instantiation
    ...
    // no more scanner close
 }


 public static void PromptCustomerPayment (Customer customer, Scanner sc) {

    // no more scanner instantiation
    ...
    // no more scanner close
 }

Hope this gives you some insight about the failure and possible resolution.

Add:

allow_url_fopen=1

in your php.ini file. If you are using shared hosting, create one first.

Calling EntityManager#flush does have side-effects. It is conveniently used for entity types with generated ID values (sequence values): such an ID is available only upon synchronization with underlying persistence layer. If this ID is required before the current transaction ends (for logging purposes for instance), flushing the session is required.

It's complaining about

COUNT(DISTINCT dNum) AS ud 

inside the subquery. Only one column can be returned from the subquery unless you are performing an exists query. I'm not sure why you want to do a count on the same column twice, superficially it looks redundant to what you are doing. The subquery here is only a filter it is not the same as a join. i.e. you use it to restrict data, not to specify what columns to get back.

require 'json/ext' # to use the C based extension instead of json/pure

puts {hash: 123}.to_json

Although you could certainly use the compareTo method on an Integer instance, it's not clear when reading the code, so you should probably avoid doing so.

Java allows you to use autoboxing (see http://java.sun.com/j2se/1.5.0/docs/guide/language/autoboxing.html) to compare directly with an int, so you can do:

if (count > 0) { }

And the Integer instance count gets automatically converted to an int for the comparison.

If you're having trouble understanding this, check out the link above, or imagine it's doing this:

if (count.intValue() > 0) { }

you can do like this also

        long[,] arr = new long[4, 4] { { 0, 0, 0, 0 }, { 1, 1, 1, 1 }, { 0, 0, 0, 0 }, { 1, 1, 1, 1 }};

        for (int i = 0; i < arr.GetLength(0); i++)
        {
            for (int j = 0; j < arr.GetLength(1); j++)
            {
                Console.Write(arr[i,j]+" ");
            }
            Console.WriteLine();
        }

You can do this with the Box component:

import Box from "@material-ui/core/Box";

...

<Box
  display="flex"
  justifyContent="center"
  alignItems="center"
  minHeight="100vh"

Coobird's answer is the correct, complete one. However, I combined his hints with those from another site to create code that works in my app (iOS/Objective-C), which I wanted to share with anyone who comes here looking for such a thing. Please, if you like/up-vote this answer, do the same for the originals; all I did was "stand on the shoulders of giants."

As for sort-order, my technique is a modified painter's algorithm: each object has (a) an altitude of the base (I call "level") and (b) an X/Y for the "base" or "foot" of the image (examples: avatar's base is at his feet; tree's base is at it's roots; airplane's base is center-image, etc.) Then I just sort lowest to highest level, then lowest (highest on-screen) to highest base-Y, then lowest (left-most) to highest base-X. This renders the tiles the way one would expect.

Code to convert screen (point) to tile (cell) and back:

typedef struct ASIntCell {  // like CGPoint, but with int-s vice float-s
    int x;
    int y;
} ASIntCell;

// Cell-math helper here:
//      http://gamedevelopment.tutsplus.com/tutorials/creating-isometric-worlds-a-primer-for-game-developers--gamedev-6511
// Although we had to rotate the coordinates because...
// X increases NE (not SE)
// Y increases SE (not SW)
+ (ASIntCell) cellForPoint: (CGPoint) point
{
    const float halfHeight = rfcRowHeight / 2.;

    ASIntCell cell;
    cell.x = ((point.x / rfcColWidth) - ((point.y - halfHeight) / rfcRowHeight));
    cell.y = ((point.x / rfcColWidth) + ((point.y + halfHeight) / rfcRowHeight));

    return cell;
}


// Cell-math helper here:
//      http://stackoverflow.com/questions/892811/drawing-isometric-game-worlds/893063
// X increases NE,
// Y increases SE
+ (CGPoint) centerForCell: (ASIntCell) cell
{
    CGPoint result;

    result.x = (cell.x * rfcColWidth  / 2) + (cell.y * rfcColWidth  / 2);
    result.y = (cell.y * rfcRowHeight / 2) - (cell.x * rfcRowHeight / 2);

    return result;
}

It may be better to use REAL type, to save storage space.

Quote from 1.2 section of Datatypes In SQLite Version 3

SQLite does not have a storage class set aside for storing dates and/or times. Instead, the built-in Date And Time Functions of SQLite are capable of storing dates and times as TEXT, REAL, or INTEGER values

CREATE TABLE test (
    id INTEGER PRIMARY KEY AUTOINCREMENT, 
    t REAL DEFAULT (datetime('now', 'localtime'))
);

see column-constraint .

And insert a row without providing any value.

INSERT INTO "test" DEFAULT VALUES;

There is a standard feature echo: in cmd/bat-files to write blank line, which emulates a new line in your cmd-output:

@echo off
@echo line1
@echo:
@echo line2

Output of cited above cmd-file:

line1

line2

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

The traditional for loop in Objective-C is inherited from standard C and takes the following form:

for (/* Instantiate local variables*/ ; /* Condition to keep looping. */ ; /* End of loop expressions */)
{
    // Do something.
}

For example, to print the numbers from 1 to 10, you could use the for loop:

for (int i = 1; i <= 10; i++)
{
    NSLog(@"%d", i);
}

On the other hand, the for in loop was introduced in Objective-C 2.0, and is used to loop through objects in a collection, such as an NSArray instance. For example, to loop through a collection of NSString objects in an NSArray and print them all out, you could use the following format.

for (NSString* currentString in myArrayOfStrings)
{
    NSLog(@"%@", currentString);
}

This is logically equivilant to the following traditional for loop:

for (int i = 0; i < [myArrayOfStrings count]; i++)
{
    NSLog(@"%@", [myArrayOfStrings objectAtIndex:i]);
}

The advantage of using the for in loop is firstly that it's a lot cleaner code to look at. Secondly, the Objective-C compiler can optimize the for in loop so as the code runs faster than doing the same thing with a traditional for loop.

Hope this helps.

To achieve this you can use:

strcpy(string, "");

Take a look at the Activator.CreateInstance method.

I am also still figuring out the internals of git, and have figured out this so far:

1. HEAD is a file in your .git/ directory that normally looks something like this:

% cat .git/HEAD
ref: refs/heads/master

2. refs/heads/master is itself a file that normally has the hash value of the latest commit:

% cat .git/refs/heads/master 
cbf01a8e629e8d884888f19ac203fa037acd901f

3. If you git checkout a remote branch that is ahead of your master, this may cause your HEAD file to be updated to contain the hash of the latest commit in the remote master:

% cat .git/HEAD
8e2c815f83231f85f067f19ed49723fd1dc023b7

This is called a detached HEAD. The remote master is ahead of your local master. When you do git submodule --remote myrepo to get the latest commit of your submodule, it will by default do a checkout, which will update HEAD. Since your current branch master is behind, HEAD becomes 'detached' from your current branch, so to speak.

There is also the MATLAB Engine for Python by MathWorks itself. If you have MATLAB, this might be worth considering (I haven't tried it myself but it has a lot more functionality than just reading MATLAB files). However, I don't know if it is allowed to distribute it to other users (it is probably not a problem if those persons have MATLAB. Otherwise, maybe NumPy is the right way to go?).

Also, if you want to do all the basics yourself, MathWorks provides (if the link changes, try to google for matfile_format.pdf or its title MAT-FILE Format) a detailed documentation on the structure of the file format. It's not as complicated as I personally thought, but obviously, this is not the easiest way to go. It also depends on how many features of the .mat-files you want to support.

I've written a "small" (about 700 lines) Python script which can read some basic .mat-files. I'm neither a Python expert nor a beginner and it took me about two days to write it (using the MathWorks documentation linked above). I've learned a lot of new stuff and it was quite fun (most of the time). As I've written the Python script at work, I'm afraid I cannot publish it... But I can give some advice here:

• First read the documentation.
• Use a hex editor (such as HxD) and look into a reference .mat-file you want to parse.
• Try to figure out the meaning of each byte by saving the bytes to a .txt file and annotate each line.
• Use classes to save each data element (such as miCOMPRESSED, miMATRIX, mxDOUBLE, or miINT32)
• The .mat-files' structure is optimal for saving the data elements in a tree data structure; each node has one class and subnodes

git reset is all about moving HEAD, and generally the branch ref.
Question: what about the working tree and index?
When employed with --soft, moves HEAD, most often updating the branch ref, and only the HEAD.
This differ from commit --amend as:

• it doesn't create a new commit.
• it can actually move HEAD to any commit (as commit --amend is only about not moving HEAD, while allowing to redo the current commit)

Just found this example of combining:

• a classic merge
• a subtree merge

all into one (octopus, since there is more than two branches merged) commit merge.

Tomas "wereHamster" Carnecky explains in his "Subtree Octopus merge" article:

• The subtree merge strategy can be used if you want to merge one project into a subdirectory of another project, and the subsequently keep the subproject up to date. It is an alternative to git submodules.
• The octopus merge strategy can be used to merge three or more branches. The normal strategy can merge only two branches and if you try to merge more than that, git automatically falls back to the octopus strategy.

The problem is that you can choose only one strategy. But I wanted to combine the two in order to get a clean history in which the whole repository is atomically updated to a new version.

I have a superproject, let's call it projectA, and a subproject, projectB, that I merged into a subdirectory of projectA.

(that's the subtree merge part)

I'm also maintaining a few local commits.
ProjectA is regularly updated, projectB has a new version every couple days or weeks and usually depends on a particular version of projectA.

When I decide to update both projects, I don't simply pull from projectA and projectB as that would create two commits for what should be an atomic update of the whole project.
Instead, I create a single merge commit which combines projectA, projectB and my local commits.
The tricky part here is that this is an octopus merge (three heads), but projectB needs to be merged with the subtree strategy. So this is what I do:

# Merge projectA with the default strategy:
git merge projectA/master

# Merge projectB with the subtree strategy:
git merge -s subtree projectB/master

Here the author used a reset --hard, and then read-tree to restore what the first two merges had done to the working tree and index, but that is where reset --soft can help:
How to I redo those two merges, which have worked, i.e. my working tree and index are fine, but without having to record those two commits?

# Move the HEAD, and just the HEAD, two commits back!
git reset --soft HEAD@{2}

Now, we can resume Tomas's solution:

# Pretend that we just did an octopus merge with three heads:
echo $(git rev-parse projectA/master) > .git/MERGE_HEAD
echo $(git rev-parse projectB/master) >> .git/MERGE_HEAD

# And finally do the commit:
git commit

So, each time:

• you are satisfied with what you end up with (in term of working tree and index)
• you are not satisfied with all the commits that took you to get there:

git reset --soft is the answer.

This will give you the path of your current working directory:

Path path = FileSystems.getDefault().getPath(".");

And this will give you the path to a file called "Foo.txt" in the working directory:

Path path = FileSystems.getDefault().getPath("Foo.txt");

Edit : To obtain an absolute path of current directory:

Path path = FileSystems.getDefault().getPath(".").toAbsolutePath();

* Update * To get current working directory:

Path path = FileSystems.getDefault().getPath("").toAbsolutePath();

When you work with web page or javascript file you want it to be reloaded every time you change it. You can change settings in IE 8 so the browser will never cache.

Follow this simple steps.

1. Select Tools-> Internet Options.
2. In General tab click on Settings button in Browsing history section.
3. Click on "Every time I visit the webpage" radio button.
4. Click OK button.

Here's an answer that doesn't involve reassignment of functions, yet still prevents the need for that ugly "is first" check.

__missing__ is supported by Python 2.5 and above.

def do_once_varname1():
    print 'performing varname1'
    return 'only done once for varname1'
def do_once_varname2():
    print 'performing varname2'
    return 'only done once for varname2'

class cdict(dict):
    def __missing__(self,key):
        val=self['do_once_'+key]()
        self[key]=val
        return val

cache_dict=cdict(do_once_varname1=do_once_varname1,do_once_varname2=do_once_varname2)

if __name__=='__main__':
    print cache_dict['varname1'] # causes 2 prints
    print cache_dict['varname2'] # causes 2 prints
    print cache_dict['varname1'] # just 1 print
    print cache_dict['varname2'] # just 1 print

Output:

performing varname1
only done once for varname1
performing varname2
only done once for varname2
only done once for varname1
only done once for varname2

jupyter notebook --ip 0.0.0.0 --port 8888 will work.

Just remove the .val(). Like:

if ( $('html').attr('lang') == 'fr-FR' ) {
    // do this
} else {
    // do that
}

If you are using jQuery UI, they already have a class the works just a charm add a <div> at the bottom inside the div that you want expand with height:auto; then add a class name ui-helper-clearfix or use this style attribute and add just like below:

<div style=" clear:both; overflow:hidden; height:1%; "></div>

add jQuery UI class to the clear div, not the div the you want to expand.

You cannot do this:

vector<string> name(5); //error in these 2 lines
vector<int> val(5,0);

in a class outside of a method.

You can initialize the data members at the point of declaration, but not with () brackets:

class Foo {
    vector<string> name = vector<string>(5);
    vector<int> val{vector<int>(5,0)};
};

Before C++11, you need to declare them first, then initialize them e.g in a contructor

class Foo {
    vector<string> name;
    vector<int> val;
 public:
  Foo() : name(5), val(5,0) {}
};

Another option is to convert the scalars into list on the fly using Dictionary Comprehension:

df = pd.DataFrame(data={k: [v] for k, v in mydict.items()})

The expression {...} creates a new dict whose values is a list of 1 element. such as :

In [20]: mydict
Out[20]: {'a': 1, 'b': 2}

In [21]: mydict2 = { k: [v] for k, v in mydict.items()}

In [22]: mydict2
Out[22]: {'a': [1], 'b': [2]}

You can use identifierForVendor public property present in UIDevice class

let UUIDValue = UIDevice.currentDevice().identifierForVendor!.UUIDString
        print("UUID: \(UUIDValue)")

EDIT Swift 3:

UIDevice.current.identifierForVendor!.uuidString

END EDIT

I got this to work by Populating a SelectListItem, converting to an List, and adding a value at index 0.

List<SelectListItem> items = new SelectList(CurrentViewSetups, "SetupId", "SetupName", setupid).ToList(); 
items.Insert(0, (new SelectListItem { Text = "[None]", Value = "0" }));
ViewData["SetupsSelectList"] = items;

Assuming you don't have extraneous whitespace:

with open('file') as f:
    w, h = [int(x) for x in next(f).split()] # read first line
    array = []
    for line in f: # read rest of lines
        array.append([int(x) for x in line.split()])

You could condense the last for loop into a nested list comprehension:

with open('file') as f:
    w, h = [int(x) for x in next(f).split()]
    array = [[int(x) for x in line.split()] for line in f]

It's simple, use:

val str: String = "%.2f".format(3.14159)

JavaScript inserted as DOM text will not execute. However, you can use the dynamic script pattern to accomplish your goal. The basic idea is to move the script that you want to execute into an external file and create a script tag when you get your Ajax response. You then set the src attribute of your script tag and voila, it loads and executes the external script.

This other StackOverflow post may also be helpful to you: Can scripts be inserted with innerHTML?.

You can still use the Authorization header with OAuth 2.0. There is a Bearer type specified in the Authorization header for use with OAuth bearer tokens (meaning the client app simply has to present ("bear") the token). The value of the header is the access token the client received from the Authorization Server.

It's documented in this spec: https://tools.ietf.org/html/rfc6750#section-2.1

E.g.:

   GET /resource HTTP/1.1
   Host: server.example.com
   Authorization: Bearer mF_9.B5f-4.1JqM

Where mF_9.B5f-4.1JqM is your OAuth access token.

Through jQuery.ready function you can specify function that's executed when DOM is loaded. Whole DOM, not any div you want.

So, you should use ready in a bit different way

$.ready(function() {
    createGrid();
});

This is in case when you dont use AJAX to load your div

I needed to capture both stdout and stderr and have it timeout if the process didn't exit when expected. I came up with this:

Process process = new Process();
StringBuilder outputStringBuilder = new StringBuilder();

try
{
process.StartInfo.FileName = exeFileName;
process.StartInfo.WorkingDirectory = args.ExeDirectory;
process.StartInfo.Arguments = args;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
process.StartInfo.CreateNoWindow = true;
process.StartInfo.UseShellExecute = false;
process.EnableRaisingEvents = false;
process.OutputDataReceived += (sender, eventArgs) => outputStringBuilder.AppendLine(eventArgs.Data);
process.ErrorDataReceived += (sender, eventArgs) => outputStringBuilder.AppendLine(eventArgs.Data);
process.Start();
process.BeginOutputReadLine();
process.BeginErrorReadLine();
var processExited = process.WaitForExit(PROCESS_TIMEOUT);

if (processExited == false) // we timed out...
{
    process.Kill();
    throw new Exception("ERROR: Process took too long to finish");
}
else if (process.ExitCode != 0)
{
    var output = outputStringBuilder.ToString();
    var prefixMessage = "";

    throw new Exception("Process exited with non-zero exit code of: " + process.ExitCode + Environment.NewLine + 
    "Output from process: " + outputStringBuilder.ToString());
}
}
finally
{                
process.Close();
}

I am piping the stdout and stderr into the same string, but you could keep it separate if needed. It uses events, so it should handle them as they come (I believe). I have run this successfully, and will be volume testing it soon.

This should work with any div or screen size:

.center-screen {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
  text-align: center;_x000D_
  min-height: 100vh;_x000D_
}

 <html>_x000D_
 <head>_x000D_
 </head>_x000D_
 <body>_x000D_
 <div class="center-screen">_x000D_
 I'm in the center_x000D_
 </div>_x000D_
 </body>_x000D_
 </html>

See more details about flex here. This should work on most of the browsers, see compatibility matrix here.

Update: If you don't want the scroll bar, make min-height smaller, for example min-height: 95vh;

Try

pip install pillow

If it doesn't work, try clearing the

cache by pip install --upgrade pip

Then again run

pip install pillow

I just received this obscure message when trying to deploy a report from BIDS.

After a little hunting I found a more descriptive error by going into the Preview window.

You can just define a function and pass it. Anonymous functions are not special in any way, all functions can be passed around as values.

var elem = document.getElementById('first');

elem.addEventListener('touchstart', handler, false);
elem.addEventListener('click', handler, false);

function handler(event) {
    do_something();
}

use the following function

left(@test, charindex('/', @test) - 1)

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

An HttpOnly cookie means that it's not available to scripting languages like JavaScript. So in JavaScript, there's absolutely no API available to get/set the HttpOnly attribute of the cookie, as that would otherwise defeat the meaning of HttpOnly.

Just set it as such on the server side using whatever server side language the server side is using. If JavaScript is absolutely necessary for this, you could consider to just let it send some (ajax) request with e.g. some specific request parameter which triggers the server side language to create an HttpOnly cookie. But, that would still make it easy for hackers to change the HttpOnly by just XSS and still have access to the cookie via JS and thus make the HttpOnly on your cookie completely useless.

Here is a dplyr/tidyverse solution using the na_if() function:

dat %>% mutate_if(is.numeric, list(~na_if(., Inf)))

Note that this only replaces positive infinity with NA. Need to repeat if negative infinity values also need to be replaced.

dat %>% mutate_if(is.numeric, list(~na_if(., Inf))) %>% 
  mutate_if(is.numeric, list(~na_if(., -Inf)))

put it in double quotes

echo "\t";

See: http://php.net/language.types.string#language.types.string.syntax.double

I agree that it is not possible in general.

The only thing CSS3 can do (which helped in my case) is to select elements that have no children:

table td:empty
{
   background-color: white;
}

Or have any children (including text):

table td:not(:empty)
{
   background-color: white;
}

See C# specification. There are three types of division operators

• Integer division
• Floating-point division
• Decimal division

In your case we have Integer division, with following rules applied:

The division rounds the result towards zero, and the absolute value of the result is the largest possible integer that is less than the absolute value of the quotient of the two operands. The result is zero or positive when the two operands have the same sign and zero or negative when the two operands have opposite signs.

I think the reason why C# use this type of division for integers (some languages return floating result) is hardware - integers division is faster and simpler.

When the DLL was created an import lib is usually automatically created and you should use that linked in to your program along with header files to call it but if not then you can manually call windows functions like LoadLibrary and GetProcAddress to get it working.

$id = intval($_GET['id']);
$sql = "SELECT * FROM student WHERE IDNO=$id";
$result = mysql_query($sql) or trigger_error(mysql_error().$sql);

always do it this way and it will tell you what is wrong

To add to Paul's answer, I found that to ultimately recover space, I have to push HEAD to a clean repository and that trims down the size of the .git/objects/pack directory.

i.e.

$ mkdir ...ABC.git
$ cd ...ABC.git
$ git init --bare

After the gc prune, also do:

$ git push ...ABC.git HEAD

Then you can do

$ git clone ...ABC.git

and the size of ABC/.git is reduced

Actually, some of the time consuming steps (e.g. git gc) aren't needed with the push to clean repository, i.e.:

$ git clone --no-hardlinks /XYZ /ABC
$ git filter-branch --subdirectory-filter ABC HEAD
$ git reset --hard
$ git push ...ABC.git HEAD

Check if string is positive digit (integer) and alphabet

You may use str.isdigit() and str.isalpha() to check whether given string is positive integer and alphabet respectively.

Sample Results:

# For alphabet
>>> 'A'.isdigit()
False
>>> 'A'.isalpha()
True

# For digit
>>> '1'.isdigit()
True
>>> '1'.isalpha()
False

Check for strings as positive/negative - integer/float

str.isdigit() returns False if the string is a negative number or a float number. For example:

# returns `False` for float
>>> '123.3'.isdigit()
False
# returns `False` for negative number
>>> '-123'.isdigit()
False

If you want to also check for the negative integers and float, then you may write a custom function to check for it as:

def is_number(n):
    try:
        float(n)   # Type-casting the string to `float`.
                   # If string is not a valid `float`, 
                   # it'll raise `ValueError` exception
    except ValueError:
        return False
    return True

Sample Run:

>>> is_number('123')    # positive integer number
True

>>> is_number('123.4')  # positive float number
True
 
>>> is_number('-123')   # negative integer number
True

>>> is_number('-123.4') # negative `float` number
True

>>> is_number('abc')    # `False` for "some random" string
False

Discard "NaN" (not a number) strings while checking for number

The above functions will return True for the "NAN" (Not a number) string because for Python it is valid float representing it is not a number. For example:

>>> is_number('NaN')
True

In order to check whether the number is "NaN", you may use math.isnan() as:

>>> import math
>>> nan_num = float('nan')

>>> math.isnan(nan_num)
True

Or if you don't want to import additional library to check this, then you may simply check it via comparing it with itself using ==. Python returns False when nan float is compared with itself. For example:

# `nan_num` variable is taken from above example
>>> nan_num == nan_num
False

Hence, above function is_number can be updated to return False for "NaN" as:

def is_number(n):
    is_number = True
    try:
        num = float(n)
        # check for "nan" floats
        is_number = num == num   # or use `math.isnan(num)`
    except ValueError:
        is_number = False
    return is_number

Sample Run:

>>> is_number('Nan')   # not a number "Nan" string
False

>>> is_number('nan')   # not a number string "nan" with all lower cased
False

>>> is_number('123')   # positive integer
True

>>> is_number('-123')  # negative integer
True

>>> is_number('-1.12') # negative `float`
True

>>> is_number('abc')   # "some random" string
False

Allow Complex Number like "1+2j" to be treated as valid number

The above function will still return you False for the complex numbers. If you want your is_number function to treat complex numbers as valid number, then you need to type cast your passed string to complex() instead of float(). Then your is_number function will look like:

def is_number(n):
    is_number = True
    try:
        #      v type-casting the number here as `complex`, instead of `float`
        num = complex(n)
        is_number = num == num
    except ValueError:
        is_number = False
    return is_number

Sample Run:

>>> is_number('1+2j')    # Valid 
True                     #      : complex number 

>>> is_number('1+ 2j')   # Invalid 
False                    #      : string with space in complex number represetantion
                         #        is treated as invalid complex number

>>> is_number('123')     # Valid
True                     #      : positive integer

>>> is_number('-123')    # Valid 
True                     #      : negative integer

>>> is_number('abc')     # Invalid 
False                    #      : some random string, not a valid number

>>> is_number('nan')     # Invalid
False                    #      : not a number "nan" string

PS: Each operation for each check depending on the type of number comes with additional overhead. Choose the version of is_number function which fits your requirement.

Overloading: In Real world, overloading means assigning some extra stuff to someone. As as in real world Overloading in PHP means calling extra functions. In other way You can say it have slimier function with different parameter.In PHP you can use overloading with magic functions e.g. __get, __set, __call etc.

Example of Overloading:

class Shape {
   const Pi = 3.142 ;  // constant value
  function __call($functionname, $argument){
    if($functionname == 'area')
    switch(count($argument)){
        case 0 : return 0 ;
        case 1 : return self::Pi * $argument[0] ; // 3.14 * 5
        case 2 : return $argument[0] * $argument[1];  // 5 * 10
    }

  }

 }
 $circle = new Shape();`enter code here`
 echo "Area of circle:".$circle->area()."</br>"; // display the area of circle Output 0
 echo "Area of circle:".$circle->area(5)."</br>"; // display the area of circle
 $rect = new Shape();
 echo "Area of rectangle:".$rect->area(5,10); // display area of rectangle

Overriding : In object oriented programming overriding is to replace parent method in child class.In overriding you can re-declare parent class method in child class. So, basically the purpose of overriding is to change the behavior of your parent class method.

Example of overriding :

class parent_class
{

  public function text()    //text() is a parent class method
  {
    echo "Hello!! everyone I am parent class text method"."</br>";
  }
  public function test()   
  {
    echo "Hello!! I am second method of parent class"."</br>";
  }

}

class child extends parent_class
{
  public function text()     // Text() parent class method which is override by child 
  class
  {
    echo "Hello!! Everyone i am child class";
  }

 }

 $obj= new parent_class();
 $obj->text();            // display the parent class method echo
 $obj= new parent_class();
 $obj->test();
 $obj= new child();
 $obj->text(); // display the child class method echo

so the .animate method works only if you have given a position attribute to an element, if not it didn't move?

for example i've seen that if i declare the div but i declare nothing in the css, it does not assume his default position and it does not move it into the page, even if i declare property margin: x w y z;

Try this code:

CONVERT(varchar(15), date_started, 103)

You have two solutions for your problem. The quick one is to lower targetApi to 22 (build.gradle file). Second is to use new and wonderful ask-for-permission model:

if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
        != PackageManager.PERMISSION_GRANTED) {

    // Should we show an explanation?
    if (shouldShowRequestPermissionRationale(
            Manifest.permission.READ_EXTERNAL_STORAGE)) {
        // Explain to the user why we need to read the contacts
    }

    requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
            MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);

    // MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
    // app-defined int constant that should be quite unique

    return;
}

Sniplet found here: https://developer.android.com/training/permissions/requesting.html

Solutions 2: If it does not work try this:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
    && ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
        REQUEST_PERMISSION);

return;

}

and then in callback

@Override
public void onRequestPermissionsResult(final int requestCode, @NonNull final String[] permissions, @NonNull final int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == REQUEST_PERMISSION) {
    if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        // Permission granted.
    } else {
        // User refused to grant permission.
    }
}
}

editText is a part of alertDialog layout so Just access editText with reference of alertDialog

EditText editText = (EditText) alertDialog.findViewById(R.id.label_field);

Update:

Because in code line dialogBuilder.setView(inflater.inflate(R.layout.alert_label_editor, null));

inflater is Null.

update your code like below, and try to understand the each code line

AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
// ...Irrelevant code for customizing the buttons and title
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.alert_label_editor, null);
dialogBuilder.setView(dialogView);

EditText editText = (EditText) dialogView.findViewById(R.id.label_field);
editText.setText("test label");
AlertDialog alertDialog = dialogBuilder.create();
alertDialog.show();

Update 2:

As you are using View object created by Inflater to update UI components else you can directly use setView(int layourResId) method of AlertDialog.Builder class, which is available from API 21 and onwards.

One more way of getting minutes and hours is by using SimpleDateFormat.

SimpleDateFormat formatMinutes = new SimpleDateFormat("mm")
String getMinutes = formatMinutes.format(new Date())

SimpleDateFormat formatHours = new SimpleDateFormat("HH")
String getHours = formatHours.format(new Date())

You need to make a second groupby object that groups by the states, and then use the div method:

import numpy as np
import pandas as pd
np.random.seed(0)
df = pd.DataFrame({'state': ['CA', 'WA', 'CO', 'AZ'] * 3,
               'office_id': list(range(1, 7)) * 2,
               'sales': [np.random.randint(100000, 999999) for _ in range(12)]})

state_office = df.groupby(['state', 'office_id']).agg({'sales': 'sum'})
state = df.groupby(['state']).agg({'sales': 'sum'})
state_office.div(state, level='state') * 100


                     sales
state office_id           
AZ    2          16.981365
      4          19.250033
      6          63.768601
CA    1          19.331879
      3          33.858747
      5          46.809373
CO    1          36.851857
      3          19.874290
      5          43.273852
WA    2          34.707233
      4          35.511259
      6          29.781508

the level='state' kwarg in div tells pandas to broadcast/join the dataframes base on the values in the state level of the index.

Obviously this is only for Pydev, but I've worked out that you can get the very useful functions "Shift Right" and "Shift Left" (mapped by default to CTRL+ALT+. and CTRL+ALT+,) to become useful by changing their keybindings to "Pydev Editor Scope" from "Pydev View"

Actually your checkAll(..) is hanging without any attachment.

1) Add onchange event handler

<th><INPUT type="checkbox" onchange="checkAll(this)" name="chk[]" /> </th>

2) Modified the code to handle check/uncheck

 function checkAll(ele) {
     var checkboxes = document.getElementsByTagName('input');
     if (ele.checked) {
         for (var i = 0; i < checkboxes.length; i++) {
             if (checkboxes[i].type == 'checkbox') {
                 checkboxes[i].checked = true;
             }
         }
     } else {
         for (var i = 0; i < checkboxes.length; i++) {
             console.log(i)
             if (checkboxes[i].type == 'checkbox') {
                 checkboxes[i].checked = false;
             }
         }
     }
 }

Here's another one for Silverlight. And a list of nice gradients to use.

with open('file.txt', 'r') as searchfile:
    for line in searchfile:
        if 'searchphrase' in line:
            print line

With apologies to senderle who I blatantly copied.

<input type="checkbox" checked="checked" />

or simply

<input type="checkbox" checked />

for checked checkbox. No checked attribute (<input type="checkbox" />) for unchecked checkbox.

Use collect($comments_collection).

Else, try json_encode($comments_collection) to convert to json.

private void WaitNSeconds(int seconds)
{
    if (seconds < 1) return;
    DateTime _desired = DateTime.Now.AddSeconds(seconds);
    while (DateTime.Now < _desired) {
         Thread.Sleep(1);
         System.Windows.Forms.Application.DoEvents();
    }
}

I don't think jQuery supports the pseudo-selectors either, but it does provide a quick way to add events to one, many, or all of your similar controls and tags on a single page.

Best of all, you can chain the event binds and do it all in one line of script if you want. Much easier than manually editing all of the HTML to turn them on or off. Then again, since you can do the same in CSS I don't know that it buys you anything (other than learning jQuery).

lst = [['a','b','c'], [1,2,3], ['x','y','z']]
outputlist = []
for values in lst:
    outputlist.append(values[0])

print(outputlist) 

Output: ['a', 1, 'x']

Done....

I hope you Find Right solution here.

Thanks.

I wondered how the functions will perform for different sets, so I did a benchmark:

from random import sample

def ForLoop(s):
    for e in s:
        break
    return e

def IterNext(s):
    return next(iter(s))

def ListIndex(s):
    return list(s)[0]

def PopAdd(s):
    e = s.pop()
    s.add(e)
    return e

def RandomSample(s):
    return sample(s, 1)

def SetUnpacking(s):
    e, *_ = s
    return e

from simple_benchmark import benchmark

b = benchmark([ForLoop, IterNext, ListIndex, PopAdd, RandomSample, SetUnpacking],
              {2**i: set(range(2**i)) for i in range(1, 20)},
              argument_name='set size',
              function_aliases={first: 'First'})

b.plot()

This plot clearly shows that some approaches (RandomSample, SetUnpacking and ListIndex) depend on the size of the set and should be avoided in the general case (at least if performance might be important). As already shown by the other answers the fastest way is ForLoop.

However as long as one of the constant time approaches is used the performance difference will be negligible.

iteration_utilities (Disclaimer: I'm the author) contains a convenience function for this use-case: first:

>>> from iteration_utilities import first
>>> first({1,2,3,4})
1

I also included it in the benchmark above. It can compete with the other two "fast" solutions but the difference isn't much either way.

//Create our own namespaces for the output
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();

//Add an empty namespace and empty value
ns.Add("", "");

//Create the serializer
XmlSerializer slz = new XmlSerializer(someType);

//Serialize the object with our own namespaces (notice the overload)
slz.Serialize(myXmlTextWriter, someObject, ns)

Check out Oj. There are gotchas when it comes to converting any old object to JSON, but Oj can do it.

require 'oj'

class A
    def initialize a=[1,2,3], b='hello'
        @a = a
        @b = b
    end
end

a = A.new
puts Oj::dump a, :indent => 2

This outputs:

{
  "^o":"A",
  "a":[
    1,
    2,
    3
  ],
 "b":"hello"
}

Note that ^o is used to designate the object's class, and is there to aid deserialization. To omit ^o, use :compat mode:

puts Oj::dump a, :indent => 2, :mode => :compat

Output:

{
  "a":[
    1,
    2,
    3
  ],
  "b":"hello"
}

You could use an input mask on the text box, too. If you set the mask to ##/##/#### it will always be formatted as you type and you don't need to do any coding other than checking to see if what was entered was a true date.

Which just a few easy lines

txtUserName.SetFocus
If IsDate(txtUserName.text) Then
    Debug.Print Format(CDate(txtUserName.text), "MM/DD/YYYY")
Else
    Debug.Print "Not a real date"
End If

If you want to pack a struct with a value <255 (one byte unsigned, uint8_t) and end up with a string of one character, you're probably looking for the format B instead of c. C converts a character to a string (not too useful by itself) while B converts an integer.

struct.pack('B', 65)

(And yes, 65 is \x41, not \x65.)

The struct class will also conveniently handle endianness for communication or other uses.

>>> item = set([0,1,2,3,4,5,6,7,8,9])
>>> z = set([2,3,4])
>>> print item - z
set([0, 1, 5, 6, 7, 8, 9])

In Netbeans 11(Gladle Project) follow these steps:

In the tab files>yourprojectname> double click in the file "build.gladle" than set in line "mainClassName:'yourpackagepath.YourMainClass'"

So, take a look here: http://www.microbion.co.uk/web/vertline.htm This link will give you a couple of tips.

The best and easiest way is auto-py-to-exe for sure, and I have given all the steps and red flags below which will take you just 5 mins to get a final .exe file as you don't have to learn anything to use it.

1.) It may not work for python 3.9 on some devices I guess.

2.) While installing python, if you had selected 'add python 3.x to path', open command prompt from start menu and you will have to type pip install auto-py-to-exe to install it. You will have to press enter on command prompt to get the result of the line that you are typing.

3.) Once it is installed, on command prompt itself, you can simply type just auto-py-to-exe to open it. It will open a new window. It may take up to a minute the first time. Also, closing command prompt will close auto-py-to-exe also so don't close it till you have your .exe file ready.

4.) There will be buttons for everything you need to make a .exe file and the screenshot of it is shared below. Also, for the icon, you need a .ico file instead of an image so to convert it, you can use https://convertio.co/

5.) If your script uses external files, you can add them through auto-py-to-exe and in the script, you will have to do some changes to their path. First, you have to write import sys if not written already, second, you have to make a variable for eg, location=getattr(sys,"_MEIPASS",".")+"/", third, the location of example.png would be location+"/example.png" if it is not in any folder.

6.) If it is showing any error, it may probably be because of a module called setuptools not being at the latest version. To upgrade it to the latest version, on command prompt, you will have to write pip install --upgrade setuptools. Also, in the script, writing import setuptools may help. If the version of setuptools is more than 50.0.0 then everything should be fine.

7.) After all these steps, in auto-py-to-exe, when the conversion is complete, the .exe file will be in the folder that you would have chosen (by default, it is 'c:/users/name/output') or it would have been removed by your antivirus if you have one. Every antivirus has different methods to restore a file so just experiment if you don't know.

Here is how the simple GUI of auto-py-to-exe can be used to make a .exe file.

you can use

df.describe() 

you will get basic statistics of the dataframe and to get mean of specific column you can use

df["columnname"].mean()

Just use a where clause that won't select any rows:

create table xyz_new as select * from xyz where 1=0;

Limitations

The following things will not be copied to the new table:

• sequences
• triggers
• indexes
• some constraints may not be copied
• materialized view logs

This also does not handle partitions

Hover your mouse cursor over the name of the array, then hover over the little (+) icon that appears.

As was posted earlier, you need to make sure you install the platform plugins when you deploy your application. Depending on how you want to deploy things, there are two methods to tell your application where the platform plugins (e.g. platforms/plugins/libqxcb.so) are at runtime which may work for you.

The first is to export the path to the directory through the QT_QPA_PLATFORM_PLUGIN_PATH variable.

QT_QPA_PLATFORM_PLUGIN_PATH=path/to/plugins ./my_qt_app

or

export QT_QPA_PLATFORM_PLUGIN_PATH=path/to/plugins
./my_qt_app

The other option, which I prefer is to create a qt.conf file in the same directory as your executable. The contents of which would be:

[Paths]
Plugins=/path/to/plugins

More information regarding this can be found here and at using qt.conf

Heap just guarantees that elements on higher levels are greater (for max-heap) or smaller (for min-heap) than elements on lower levels, whereas BST guarantees order (from "left" to "right"). If you want sorted elements, go with BST.

Make sure you properly escape the quotes.

  string line = "\"Text\",\"Text\",\"Text\",";

  string result = line.Replace("\",\"", ";");

Try putting a space before each \;

Works:

find . -name "*.log" -exec echo {} \;

Doesn't Work:

find . -name "*.log" -exec echo {}\;

I think all the answers are lacking something. I prefer using something like this

$('li.current_sub').prevUntil("li.par_cat").prev();

Saves you not adding :first inside the selector and is easier to read and understand. prevUntil() method has a better performance as well rather than using prevAll()

This is how I'd do it within DB2 SQL, I believe the RRN (relative record number) is stored within the table by the O/S;

SELECT * FROM (                        
   SELECT RRN(FOO) AS RRN, FOO.*
   FROM FOO                         
   ORDER BY RRN(FOO)) BAR             
 WHERE BAR.RRN = recordnumber

Another nifty way is:

DATEADD(dd, 0, DATEDIFF(dd, 0, [YourDate]))

Which gets the number of days from DAY 0 to YourDate and the adds it to DAY 0 to set the baseline again. This method (or "derivatives" hereof) can be used for a bunch of other date manipulation.

Edit - other date calculations:

First Day of Month:

DATEADD(mm, DATEDIFF(mm, 0, getdate()), 0)

First Day of the Year:

DATEADD(yy, DATEDIFF(yy, 0, getdate()), 0)

First Day of the Quarter:

DATEADD(qq, DATEDIFF(qq, 0, getdate()), 0)

Last Day of Prior Month:

DATEADD(ms, -3, DATEADD(mm, DATEDIFF(mm, 0, getdate()), 0))

Last Day of Current Month:

DATEADD(ms, -3, DATEADD(mm, DATEDIFF(m, 0, getdate()) + 1, 0))

Last Day of Current Year:

DATEADD(ms, -3, DATEADD(yy, DATEDIFF(yy, 0, getdate()) + 1, 0))

First Monday of the Month:

DATEADD(wk, DATEDIFF(wk, 0, DATEADD(dd, 6 - DATEPART(day, getdate()), getdate())), 0)        

Edit: True, Joe, it does not add it to DAY 0, it adds 0 (days) to the number of days which basically just converts it back to a datetime.

It must be a configuration problem. Your pom is fine.

Here's what I did. New folder, put your pom inside. Then in eclipse: import -> maven -> existing maven project. Dependencies got included in the project.

I did this using eclipse helios. I think the plugin version I am using is 0.12

You should check the maven properties in eclipse.

I did not see this answer but hey this is what I do :

SELECT name FROM databaseName.sys.Tables;

Now there is the pandas_profiling package, which is a more complete alternative to df.describe().

If your pandas dataframe is df, the below will return a complete analysis including some warnings about missing values, skewness, etc. It presents histograms and correlation plots as well.

import pandas_profiling
pandas_profiling.ProfileReport(df)

See the example notebook detailing the usage.

Your css will only work in IE browser. And the css suggessted by hayk.mart will olny work in webkit browsers. And by using different css hacks you can't style your browsers scroll bars with a same result.

So, it is better to use a jQuery/Javascript plugin to achieve a cross browser solution with a same result.

Solution:

By Using jScrollPane a jQuery plugin, you can achieve a cross browser solution

See This Demo

As I had the same question, but didn't find the answer here, I made some tests in order to figure out what the difference actually is. I did this, since I need the encoding for something, which is not URL/URI related.

• encodeURIComponent("A") returns "A", it does not encode "A" to "%41"
• decodeURIComponent("%41") returns "A".
• encodeURI("A") returns "A", it does not encode "A" to "%41"
• decodeURI("%41") returns "A".

-That means both can decode alphanumeric characters, even though they did not encode them. However...

• encodeURIComponent("&") returns "%26".
• decodeURIComponent("%26") returns "&".
• encodeURI("&") returns "&".
• decodeURI("%26") returns "%26".

Even though encodeURIComponent does not encode all characters, decodeURIComponent can decode any value between %00 and %7F.

Note: It appears that if you try to decode a value above %7F (unless it's a unicode value), then your script will fail with an "URI error".

Here's a working solution that creates admin-user user with a password, additional database (test-database), and test-user in that database.

Dockerfile:

FROM mongo:4.0.3

ENV MONGO_INITDB_ROOT_USERNAME admin-user
ENV MONGO_INITDB_ROOT_PASSWORD admin-password
ENV MONGO_INITDB_DATABASE admin

ADD mongo-init.js /docker-entrypoint-initdb.d/

mongo-init.js:

db.auth('admin-user', 'admin-password')

db = db.getSiblingDB('test-database')

db.createUser({
  user: 'test-user',
  pwd: 'test-password',
  roles: [
    {
      role: 'root',
      db: 'test-database',
    },
  ],
});

The tricky part was to understand that *.js files were run unauthenticated. The solution authenticates the script as the admin-user in the admin database. MONGO_INITDB_DATABASE admin is essential, otherwise the script would be executed against the test db. Check the source code of docker-entrypoint.sh.

You could use a projection with a statement lambda, but the original foreach loop is more readable and is editing the list in place rather than creating a new list.

var result = list.Select(i => 
   { 
      if (i.Name == "height") i.Value = 30;
      return i; 
   }).ToList();

Extension Method

public static IEnumerable<MyClass> SetHeights(
    this IEnumerable<MyClass> source, int value)
{
    foreach (var item in source)
    {
       if (item.Name == "height")
       {
           item.Value = value;
       }

       yield return item;
    } 
}

var result = list.SetHeights(30).ToList();

In getUserById you shouldn't create a new object (user1) which isn't used. Just assign it to the already (but null) initialized user. Otherwise Hibernate.initialize(user); is actually Hibernate.initialize(null);

Here's the new getUserById (I haven't tested this ;)):

public User getUserById(Long user_id) {
    Session session = null;
    Object user = null;
    try {
        session = HibernateUtil.getSessionFactory().openSession();
        user = (User)session.load(User.class, user_id);
        Hibernate.initialize(user);
    } catch (Exception e) {
       e.printStackTrace();

You can't easily decrypt the password from the hash string that you see. You should rather replace the hash string with a new one from a password that you do know.

There's a good howto here:

https://jakebillo.com/wordpress-phpass-generator-resetting-or-creating-a-new-admin-user/

Basically:

1. generate a new hash from a known password using e.g. http://scriptserver.mainframe8.com/wordpress_password_hasher.php, as described in the above link, or any other product that uses the phpass library,
2. use your DB interface (e.g. phpMyAdmin) to update the user_pass field with the new hash string.

If you have more users in this WordPress installation, you can also copy the hash string from one user whose password you know, to the other user (admin).
