At this time, the only video codec that truly supports an alpha channel is VP8, which Flash uses. MP4 would probably support it if the video was exported as an image sequence, but I'm fairly certain Ogg video files have no support whatsoever for an alpha channel. This might be one of those rare instances where sticking with Flash would serve you better.

This is caused by the limited support for the MP4 format within the video tag in Firefox. Support was not added until Firefox 21, and it is still limited to Windows 7 and above. The main reason for the limited support revolves around the royalty fee attached to the mp4 format.

Check out Supported media formats and Media formats supported by the audio and video elements directly from the Mozilla crew or the following blog post for more information:

Most likely the TinyMce editor is adding its own formatting to the post. You'll need to see how you can escape TinyMce's editing abilities. The code works fine for me. Is it a wordpress blog?

using that code wil give you a responsive video player with full control

<div class="embed-responsive embed-responsive-16by9">

This is the reason why mkv is such a good container, especially now that it's mature:

mkvmerge -o output.mkv video.mp4 subtitle.srt

I found the pipe operator did not work for me when using option 3 to concat several MP4s on a Mac in the accepted answer.

The following one-liner works on a Mac (High Sierra) to concatenate mp4s, with no intermediary file creation required.

ffmpeg -f concat -safe 0 -i <(for f in ./*.mp4; do echo "file '$PWD/$f'"; done) -c copy output.mp4

Use Like this:

Uri uri = Uri.parse(URL); //Declare your url here.

VideoView mVideoView  = (VideoView)findViewById(R.id.videoview)
mVideoView.setMediaController(new MediaController(this));       
mVideoView.setVideoURI(uri);
mVideoView.requestFocus();
mVideoView.start();

Another Method:

  String LINK = "type_here_the_link";
  VideoView mVideoView  = (VideoView) findViewById(R.id.videoview);
  MediaController mc = new MediaController(this);
  mc.setAnchorView(videoView);
  mc.setMediaPlayer(videoView);
  Uri video = Uri.parse(LINK);
  mVideoView.setMediaController(mc);
  mVideoView.setVideoURI(video);
  mVideoView.start();

If you are getting this error Couldn't open file on client side, trying server side Error in Android. and also Refer this. Hope this will give you some solution.

JSONP is a good option, but there is an easier way. You can simply set the Access-Control-Allow-Origin header on your server. Setting it to * will accept cross-domain AJAX requests from any domain. (https://developer.mozilla.org/en/http_access_control)

The method to do this will vary from language to language, of course. Here it is in Rails:

class HelloController < ApplicationController
  def say_hello
    headers['Access-Control-Allow-Origin'] = "*"
    render text: "hello!"
  end
end

In this example, the say_hello action will accept AJAX requests from any domain and return a response of "hello!".

Here is an example of the headers it might return:

HTTP/1.1 200 OK 
Access-Control-Allow-Origin: *
Cache-Control: no-cache, no-store, max-age=0, must-revalidate
Content-Type: text/html; charset=utf-8

Easy as it is, it does have some browser limitations. See http://caniuse.com/#feat=cors.

I did all the tricks here on My Fork to fix page 404 on Github Page but it kept 404'ing.

Finaly found that my browser hardly keep the 10 minutes cache before it up on the web.

As Marc says, you run it exactly like you would from the command line. See Creating SQL Server Agent Jobs on MSDN.

Here is an immutable version for those who are interested:

function immutableMove(arr, from, to) {
  return arr.reduce((prev, current, idx, self) => {
    if (from === to) {
      prev.push(current);
    }
    if (idx === from) {
      return prev;
    }
    if (from < to) {
      prev.push(current);
    }
    if (idx === to) {
      prev.push(self[from]);
    }
    if (from > to) {
      prev.push(current);
    }
    return prev;
  }, []);
}

I tend to look at it from the inverse perspective which may be what you intended:

What characters do I want to allow?

This is because there could be lots of characters that make in into a string somehow that blow stuff up that you wouldn't expect.

For example this one only allows for letters and numbers removing groups of invalid characters replacing them with a hypen:

"This¢£«±Ÿ÷could&*()\/<>be!@#$%^bad".replace(/([^a-z0-9]+)/gi, '-');
//Result: "This-could-be-bad"

Might want to try instance_values. That worked for me.

Another method using a regular expression (this is more correct than Zachary's answer):

var string1 = 'someText',
    string2 = 'SometexT',
    regex = new RegExp('^' + string1 + '$', 'i');

if (regex.test(string2)) {
    return true;
}

RegExp.test() will return true or false.

Also, adding the '^' (signifying the start of the string) to the beginning and '$' (signifying the end of the string) to the end make sure that your regular expression will match only if 'sometext' is the only text in stringToTest. If you're looking for text that contains the regular expression, it's ok to leave those off.

It might just be easier to use the string.toLowerCase() method.

So... regular expressions are powerful, but you should only use them if you understand how they work. Unexpected things can happen when you use something you don't understand.

There are tons of regular expression 'tutorials', but most appear to be trying to push a certain product. Here's what looks like a decent tutorial... granted, it's written for using php, but otherwise, it appears to be a nice beginner's tutorial: http://weblogtoolscollection.com/regex/regex.php

This appears to be a good tool to test regular expressions: http://gskinner.com/RegExr/

Basically an index is a map of all your keys that is sorted in order. With a list in order, then instead of checking every key, it can do something like this:

1: Go to middle of list - is higher or lower than what I'm looking for?

2: If higher, go to halfway point between middle and bottom, if lower, middle and top

3: Is higher or lower? Jump to middle point again, etc.

Using that logic, you can find an element in a sorted list in about 7 steps, instead of checking every item.

Obviously there are complexities, but that gives you the basic idea.

The error is telling you that you are importing incorrectly. The code you have now:

import { Home } from './layouts/Home';

Is incorrect because you're exporting as the default export, not as a named export. Check this line:

export default Home;

You're exporting as default, not as a name. Thus, import Home like this:

import Home from './layouts/Home';

Notice there are no curly brackets. Further reading on import and export.

I was getting an exception telling me that the file was already mapped in another workspace: "The path {File Path} is already mapped in workspace {Workspace Name}."

This workspace was deleted beofre. With the help of friend of mine I found out that TFS save workspace info under the user local settings dir. We found a file named:

VersionControl.config under {User Documents and Settings dir}\Local Settings\Application Data\Microsoft\Team Foundation\1.0\Cache. This file contains all the local mapping of TFS. Probably when you use the Map method and don't use: public void DeleteMapping(WorkingFolder mapping); before deleting the workspace the mapping information is not removed from this file which is used by TFS to check if you've alreay mapped a specific path.

To resolve this problem delete all the keys from the config file. Don't delete the file because you'll get it again from the server cache.

Git 2.6 (Sept/Oct 2015) will add the option --name-only to simplify the output of a git config -l:

See commit a92330d, commit f225987, commit 9f1429d (20 Aug 2015) by Jeff King (peff).
See commit ebca2d4 (20 Aug 2015), and commit 905f203, commit 578625f (10 Aug 2015) by SZEDER Gábor (szeder).
^{(Merged by Junio C Hamano -- gitster -- in commit fc9dfda, 31 Aug 2015)}

config: add '--name-only' option to list only variable names

'git config' can only show values or name-value pairs, so if a shell script needs the names of set config variables it has to run 'git config --list' or '--get-regexp' and parse the output to separate config variable names from their values.
However, such a parsing can't cope with multi-line values.

Though 'git config' can produce null-terminated output for newline-safe parsing, that's of no use in such a case, because shells can't cope with null characters.

Even our own bash completion script suffers from these issues.

Help the completion script, and shell scripts in general, by introducing the '--name-only' option to modify the output of '--list' and '--get-regexp' to list only the names of config variables, so they don't have to perform error-prone post processing to separate variable names from their values anymore.

Try to go around the problem for the case, the calass of which you want to set/get data is one of your own classes.

Just create a public setter(Field f, Object value) and public Object getter(Field f) for that. You can even do some securoty check on your own inside theses member functions. E.g. for the setter:

class myClassName {
    private String aString;

    public set(Field field, Object value) {
        // (A) do some checkings here  for security

        // (B) set the value
        field.set(this, value);
    }
}

Of course, now you have to find out the java.lang.reflect.Field for sString prior to setting of field value.

I do use this technique in a generic ResultSet-to-and-from-model-mapper.

The simplest answer is what Paul H said:

d = []
for p in game.players.passing():
    d.append(
        {
            'Player': p,
            'Team': p.team,
            'Passer Rating':  p.passer_rating()
        }
    )

pd.DataFrame(d)

But if you really want to "build and fill a dataframe from a loop", (which, btw, I wouldn't recommend), here's how you'd do it.

d = pd.DataFrame()

for p in game.players.passing():
    temp = pd.DataFrame(
        {
            'Player': p,
            'Team': p.team,
            'Passer Rating': p.passer_rating()
        }
    )

    d = pd.concat([d, temp])

A recursive method to check if a Class<?> is a sub class of another Class<?>...

Improved version of @To Kra's answer:

protected boolean isSubclassOf(Class<?> clazz, Class<?> superClass) {
    if (superClass.equals(Object.class)) {
        // Every class is an Object.
        return true;
    }
    if (clazz.equals(superClass)) {
        return true;
    } else {
        clazz = clazz.getSuperclass();
        // every class is Object, but superClass is below Object
        if (clazz.equals(Object.class)) {
            // we've reached the top of the hierarchy, but superClass couldn't be found.
            return false;
        }
        // try the next level up the hierarchy.
        return isSubclassOf(clazz, superClass);
    }
}

You can test if it actually is in the PATH, if you open a cmd and type in chromedriver (assuming your chromedriver executable is still named like this) and hit Enter. If Starting ChromeDriver 2.15.322448 is appearing, the PATH is set appropriately and there is something else going wrong.

Alternatively you can use a direct path to the chromedriver like this:

 driver = webdriver.Chrome('/path/to/chromedriver') 

So in your specific case:

 driver = webdriver.Chrome("C:/Users/michael/Downloads/chromedriver_win32/chromedriver.exe")

for more exactly positioning:

      background-position: bottom 5px right 7px;

You can just do:

echo $xml['token'];

RSA
RSA encryption and decryption are commutative
hence it may be used directly as a digital signature scheme
given an RSA scheme {(e,R), (d,p,q)}
to sign a message M, compute:
S = M power d (mod R)
to verify a signature, compute:
M = S power e(mod R) = M power e.d(mod R) = M(mod R)

RSA can be used both for encryption and digital signatures, simply by reversing the order in which the exponents are used: the secret exponent (d) to create the signature, the public exponent (e) for anyone to verify the signature. Everything else is identical.

DSA (Digital Signature Algorithm)
DSA is a variant on the ElGamal and Schnorr algorithms. It creates a 320 bit signature, but with 512-1024 bit security again rests on difficulty of computing discrete logarithms has been quite widely accepted.

DSA Key Generation
firstly shared global public key values (p,q,g) are chosen:
choose a large prime p = 2 power L
where L= 512 to 1024 bits and is a multiple of 64
choose q, a 160 bit prime factor of p-1
choose g = h power (p-1)/q
for any h<p-1, h(p-1)/q(mod p)>1
then each user chooses a private key and computes their public key:
choose x<q
compute y = g power x(mod p)

DSA key generation is related to, but somewhat more complex than El Gamal. Mostly because of the use of the secondary 160-bit modulus q used to help speed up calculations and reduce the size of the resulting signature.

DSA Signature Creation and Verification

to sign a message M
generate random signature key k, k<q
compute
r = (g power k(mod p))(mod q)
s = k-1.SHA(M)+ x.r (mod q)
send signature (r,s) with message

to verify a signature, compute:
w = s-1(mod q)
u1= (SHA(M).w)(mod q)
u2= r.w(mod q)
v = (g power u1.y power u2(mod p))(mod q)
if v=r then the signature is verified

Signature creation is again similar to ElGamal with the use of a per message temporary signature key k, but doing calc first mod p, then mod q to reduce the size of the result. Note that the use of the hash function SHA is explicit here. Verification also consists of comparing two computations, again being a bit more complex than, but related to El Gamal.
Note that nearly all the calculations are mod q, and hence are much faster.
But, In contrast to RSA, DSA can be used only for digital signatures

DSA Security
The presence of a subliminal channel exists in many schemes (any that need a random number to be chosen), not just DSA. It emphasises the need for "system security", not just a good algorithm.

One simple method is to use place to use an image as a background image. This is the type of thing that place is really good at doing.

For example:

background_image=tk.PhotoImage(...)
background_label = tk.Label(parent, image=background_image)
background_label.place(x=0, y=0, relwidth=1, relheight=1)

You can then grid or pack other widgets in the parent as normal. Just make sure you create the background label first so it has a lower stacking order.

Note: if you are doing this inside a function, make sure you keep a reference to the image, otherwise the image will be destroyed by the garbage collector when the function returns. A common technique is to add a reference as an attribute of the label object:

background_label.image = background_image

In addition to the fine answers above, I think it should be said that Tomcat has it's own HTTP server built into it, and is fully functional at serving static content too. Depending on your java virtual machine configuration it can actually outperform going through traditional connectors in apache such as mod_proxy and mod_jk.

That said a fully optimized Tomcat server should serve static files fast and if you have Java servlets, JSPs and ColdFusion files in addition to static content you may find tomcat does an excellent job by itself.

Take a peek at the ng-click directive source:

...
compile: function($element, attr) {
  var fn = $parse(attr[directiveName]);
  return function(scope, element, attr) {
    element.on(lowercase(name), function(event) {
      scope.$apply(function() {
        fn(scope, {$event:event});
      });
    });
  };
}

It shows how the event object is being passed on to the ng-click expression, using $event as a name of the parameter. This is done by the $parse service, which doesn't allow for the parameters to bleed into the target scope, which means the answer is no, you can't access the $event object any other way but through the callback parameter.

I have used the following two:

1 - select id from table_name where id = (select MAX(id) from table_name)
2 - select id from table_name order by id desc limit 0, 1

Use a hash tag.

May not be exactly what you want but it solves the problem of removing the extension.

Say you have a html page saved as about.html and you don't want that pesky extension you could use a hash tag and redirect to the correct page.

switch(window.location.hash.substring(1)){
      case 'about':
      window.location = 'about.html';
      break;
  }

Routing to yoursite.com#about will take you to yoursite.com/about.html. I used this to make my links cleaner.

Why not use a Pivot?

I wouldn't even pay attention to the contents of the parens.

Just match any line that starts with for and ends with semi-colon:

^\t*for.+;$

Unless you've got for statements split over multiple lines, that will work fine?

if you need to find square root without using sqrt(),use root=pow(x,0.5).

Where x is value whose square root you need to find.

It happened that I needed to link a data model of a person with a form, what I did was a direct mapping of the data with the form.

For example if the model had something like:

$scope.model.people.name

The control input of the form:

<input type="text" name="namePeople" model="model.people.name">

That way if you modify the value of the object controller, this will be reflected automatically in the view.

An example where I passed the model is updated from server data is when you ask for a zip code and zip code based on written loads a list of colonies and cities associated with that view, and by default set the first value with the user. And this I worked very well, what does happen, is that angularJS sometimes takes a few seconds to refresh the model, to do this you can put a spinner while displaying the data.

I just did something like this. My solution for this was to replace the interior for loop with a list comprehension.

for ii in range(200):
    done = any([op(ii, jj) for jj in range(200, 400)])
    ...block0...
    if done:
        continue
    ...block1...

where op is some boolean operator acting on a combination of ii and jj. In my case, if any of the operations returned true, I was done.

This is really not that different from breaking the code out into a function, but I thought that using the "any" operator to do a logical OR on a list of booleans and doing the logic all in one line was interesting. It also avoids the function call.

Building for newer Raspbian Debian Buster images and ARMv6

The answer by @Stenyg only works for older Raspbian images. The recently released Raspbian based on Debian Buster requires an updated toolchain:

In Debian Buster the gcc compiler and glibc was updated to version 8.3. The toolchain in git://github.com/raspberrypi/tools.git is still based on the older gcc 6 version. This means that using git://github.com/raspberrypi/tools.git will lead to many compile errors.

This tutorial is based on @Stenyg answer. In addition to many other solutions in the internet, this tutorial also supports older Rasperry Pi (A, B, B+, Zero) based on the ARMv6 CPU. See also: GCC 8 Cross Compiler outputs ARMv7 executable instead of ARMv6

Set up the toolchain

There is no official git repository containing an updated toolchain (See https://github.com/raspberrypi/tools/issues/102).

I created a new github repository which includes building and precompiled toolchains for ARMv6 based on GCC8 and newer:

https://github.com/Pro/raspi-toolchain

As mentioned in the project's readme, these are the steps to get the toolchain. You can also build it yourself (see the README for further details).

1. Download the toolchain:

wget https://github.com/Pro/raspi-toolchain/releases/latest/download/raspi-toolchain.tar.gz

2. Extract it. Note: The toolchain has to be in /opt/cross-pi-gcc since it's not location independent.

sudo tar xfz raspi-toolchain.tar.gz --strip-components=1 -C /opt

3. You are done! The toolchain is now in /opt/cross-pi-gcc

4. Optional, add the toolchain to your path, by adding:

export PATH=$PATH:/opt/cross-pi-gcc/bin

to the end of the file named ~/.bashrc

Now you can either log out and log back in (i.e. restart your terminal session), or run . ~/.bashrc in your terminal to pick up the PATH addition in your current terminal session.

Get the libraries from the Raspberry PI

To cross-compile for your own Raspberry Pi, which may have some custom libraries installed, you need to get these libraries onto your host.

Create a folder $HOME/raspberrypi. In your raspberrypi folder, make a folder called rootfs.

Now you need to copy the entire /liband /usr directory to this newly created folder. I usually bring the rpi image up and copy it via rsync:

rsync -vR --progress -rl --delete-after --safe-links [email protected]:/{lib,usr,opt/vc/lib} $HOME/raspberrypi/rootfs

where 192.168.1.PI is replaced by the IP of your Raspberry Pi.

Use CMake to compile your project

To tell CMake to take your own toolchain, you need to have a toolchain file which initializes the compiler settings.

Get this toolchain file from here: https://github.com/Pro/raspi-toolchain/blob/master/Toolchain-rpi.cmake

Now you should be able to compile your cmake programs simply by adding this extra flag: -D CMAKE_TOOLCHAIN_FILE=$HOME/raspberrypi/pi.cmake and setting the correct environment variables:

export RASPBIAN_ROOTFS=$HOME/raspberry/rootfs
export PATH=/opt/cross-pi-gcc/bin:$PATH
export RASPBERRY_VERSION=1
cmake -DCMAKE_TOOLCHAIN_FILE=$HOME/raspberry/Toolchain-rpi.cmake ..

An example hello world is shown here: https://github.com/Pro/raspi-toolchain/blob/master/build_hello_world.sh

koding.com has a free VM running Ubuntu. The specs are pretty good, 1 gig memory for example. They have a terminal online you can access through their website, or use SSH. The VM will go to sleep approximately 20 minutes after you log out. The reason is to discourage users from running live production code on the VM. The VM resides behind a proxy. Running web servers that only speak HTTP (port 80) should work just fine, but I think you'll get into a lot of trouble whenever you want to work directly with other ports. Many mind-like alternatives offer similar setups. Good luck!

I had the same idea as you but given all restrictions everybody keep imposing everywhere I feel that I must go out and pay for a VPS.

Just for others: be sure it is new RuntimeException, not new RuntimeErrorException which needs error as an argument.

I found it easiest to just read the entire line into one column then parse out the data using XML.

If you don't like public static initializer, reflection can be a workaround.

<?php

class LanguageUtility
{
    public static function initializeClass($class)
    {
        try
        {
            // Get a static method named 'initialize'. If not found,
            // ReflectionMethod() will throw a ReflectionException.
            $ref = new \ReflectionMethod($class, 'initialize');

            // The 'initialize' method is probably 'private'.
            // Make it accessible before calling 'invoke'.
            // Note that 'setAccessible' is not available
            // before PHP version 5.3.2.
            $ref->setAccessible(true);

            // Execute the 'initialize' method.
            $ref->invoke(null);
        }   
        catch (Exception $e)
        {
        }
    }
}

class MyClass
{
    private static function initialize()
    {
    }
}

LanguageUtility::initializeClass('MyClass');

?>

What I do so I don't specify a time zone is,

System.out.println("ldt " + LocalDateTime.now().atZone(ZoneId.systemDefault()).toInstant().toEpochMilli());
System.out.println("ctm " + System.currentTimeMillis());

gives

ldt 1424812121078 
ctm 1424812121281

As you can see the numbers are the same except for a small execution time.

Just in case you don't like System.currentTimeMillis, use Instant.now().toEpochMilli()

Here is maybe a more elegant and flexible solution with 'resolve' configuration property and 'promises' enabling eventual data loading on routing and routing rules depending on data.

You specify a function in 'resolve' in routing config and in the function load and check data, do all redirects. If you need to load data, you return a promise, if you need to do redirect - reject promise before that. All details can be found on $routerProvider and $q documentation pages.

'use strict';

var app = angular.module('app', [])
    .config(['$routeProvider', function($routeProvider) {
        $routeProvider
            .when('/', {
                templateUrl: "login.html",
                controller: LoginController
            })

                templateUrl: "private.html",
                controller: PrivateController,
                resolve: {

                controller: AnotherPriveController,
                resolve: {
                    factory: checkRouting
                }
            })
            .otherwise({ redirectTo: '/' });
    }]);

var checkRouting= function ($q, $rootScope, $location) {
    if ($rootScope.userProfile) {
        return true;
    } else {
        var deferred = $q.defer();
        $http.post("/loadUserProfile", { userToken: "blah" })
            .success(function (response) {
                $rootScope.userProfile = response.userProfile;
                deferred.resolve(true);
            })
            .error(function () {
                deferred.reject();
                $location.path("/");

I had the same issue but none of these solutions worked correctly. Finally, I have installed packages via yarn, which is npm-compatible. As per official website:

Migrating from npm should be a fairly easy process for most users. Yarn can consume the same package.json format as npm, and can install any package from the npm registry.

Just install the yarn and then then, run the install by using the following command, the equivalent to npm install in yarn:

yarn install

You can access the namespace's dictionary with vars():

>>> import argparse
>>> args = argparse.Namespace()
>>> args.foo = 1
>>> args.bar = [1,2,3]
>>> d = vars(args)
>>> d
{'foo': 1, 'bar': [1, 2, 3]}

You can modify the dictionary directly if you wish:

>>> d['baz'] = 'store me'
>>> args.baz
'store me'

Yes, it is okay to access the __dict__ attribute. It is a well-defined, tested, and guaranteed behavior.

If you want to simulate the old anonymous way in Kotlin I found this worked perfectly.

 btnNewWay!!.setOnClickListener(object:View.OnClickListener {
    override fun onClick(v: View?) {
        //Your Code Here!
    }})

#!/usr/bin/python

# encoding=utf8

Try This to starting of python file

In my case I had special instruction into nginx configuration file:

location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
            try_files $uri =404;
    }

All clients have received '404' because nginx nothing known about Flask.

I hope it help someone.

Ok, that is ?? NOT ?? the thousands repeat of add it to your Manifest, but an hint which base on this, but give you additional Benefit (and maybe some Background Info).

Android has a kind of overwriting functionality for the src-Directory.

By default, you have

/app/src/main

But you can add additional directories to overwrite your AndroidManifest.xml. Here is how it works:

• Create the Directory /app/src/debug
• Inside create the AndroidManifest.xml

Inside of this File, you don't have to put all the Rules inside, but only the ones you like to overwrite from your /app/src/main/AndroidManifest.xml

Here an Example how it looks like for the requested CLEARTEXT-Permission:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.yourappname">

    <application
            android:usesCleartextTraffic="true"
            android:name=".MainApplication"
            android:label="@string/app_name"
            android:icon="@mipmap/ic_launcher"
            android:allowBackup="false"
            android:theme="@style/AppTheme">
    </application>

</manifest>

With this knowledge it's now easy as 1,2,3 for you to overload your Permissions depending on your debug | main | release Enviroment.

The big benefit on it... you don't have debug-stuff in your production-Manifest and you keep an straight and easy maintainable structure

On Windows:

Go to Win -> Control Panel -> Credential Manager -> Windows Credentials

Search for github address and remove it.

Then try to execute:

git push -u origin master

Windows will ask for your git credentials again, put the right ones and that's it.

You're receiving this error because you did not pass a data variable to the DHT constructor.

aIKid and Alexander's answers are nice but it wont work because you still have to initialize self.data in the class constructor like this:

class DHT:
   def __init__(self, data=None):
      if data is None:
         data = {}
      else:
         self.data = data
      self.data['one'] = '1'
      self.data['two'] = '2'
      self.data['three'] = '3'
   def showData(self):
      print(self.data)

And then calling the method showData like this:

DHT().showData()

Or like this:

DHT({'six':6,'seven':'7'}).showData()

or like this:

# Build the class first
dht = DHT({'six':6,'seven':'7'})
# The call whatever method you want (In our case only 1 method available)
dht.showData()

Decode the JSON string using json_decode() and then loop through it using a regular loop:

$arr = json_decode('[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]');

foreach($arr as $item) { //foreach element in $arr
    $uses = $item['var1']; //etc
}

Before asking questions of this kind, please check MSDN documentation.

When you divide two integers, the result is always an integer. For example, the result of 7 / 3 is 2. To determine the remainder of 7 / 3, use the remainder operator (%).

int a = 5;
int b = 3;

int div = a / b; //quotient is 1
int mod = a % b; //remainder is 2

Your code looks correct. My suggestion is that the database already thinks it's upgraded. If you executed the project after incrementing the version number, but before adding the execSQL call, the database on your test device/emulator may already believe it's at version 2.

A quick way to verify this would be to change the version number to 3 -- if it upgrades after that, you know it was just because your device believed it was already upgraded.

If you're seeking a pointer style aliasing approach, so that you don't even need to allocate space and copy the data then I believe you're out of luck.

System.arraycopy() will copy from your source to destination, and efficiency is claimed for this utility. You do need to allocate the destination array.

An updated answer (October 2014)

I was really annoyed about this string natural sorting order so I took quite some time to investigate this issue. I hope this helps.

Long story short

localeCompare() character support is badass, just use it. As pointed out by Shog9, the answer to your question is:

return item1.attr.localeCompare(item2.attr);

Bugs found in all the custom javascript "natural string sort order" implementations

There are quite a bunch of custom implementations out there, trying to do string comparison more precisely called "natural string sort order"

When "playing" with these implementations, I always noticed some strange "natural sorting order" choice, or rather mistakes (or omissions in the best cases).

Typically, special characters (space, dash, ampersand, brackets, and so on) are not processed correctly.

You will then find them appearing mixed up in different places, typically that could be:

• some will be between the uppercase 'Z' and the lowercase 'a'
• some will be between the '9' and the uppercase 'A'
• some will be after lowercase 'z'

When one would have expected special characters to all be "grouped" together in one place, except for the space special character maybe (which would always be the first character). That is, either all before numbers, or all between numbers and letters (lowercase & uppercase being "together" one after another), or all after letters.

My conclusion is that they all fail to provide a consistent order when I start adding barely unusual characters (ie. characters with diacritics or charcters such as dash, exclamation mark and so on).

Research on the custom implementations:

• Natural Compare Lite https://github.com/litejs/natural-compare-lite : Fails at sorting consistently https://github.com/litejs/natural-compare-lite/issues/1 and http://jsbin.com/bevututodavi/1/edit?js,console , basic latin characters sorting http://jsbin.com/bevututodavi/5/edit?js,console
• Natural Sort https://github.com/javve/natural-sort : Fails at sorting consistently, see issue https://github.com/javve/natural-sort/issues/7 and see basic latin characters sorting http://jsbin.com/cipimosedoqe/3/edit?js,console
• Javascript Natural Sort https://github.com/overset/javascript-natural-sort : seems rather neglected since February 2012, Fails at sorting consistently, see issue https://github.com/overset/javascript-natural-sort/issues/16
• Alphanum http://www.davekoelle.com/files/alphanum.js , Fails at sorting consistently, see http://jsbin.com/tuminoxifuyo/1/edit?js,console

Browsers' native "natural string sort order" implementations via localeCompare()

localeCompare() oldest implementation (without the locales and options arguments) is supported by IE6+, see http://msdn.microsoft.com/en-us/library/ie/s4esdbwz(v=vs.94).aspx (scroll down to localeCompare() method). The built-in localeCompare() method does a much better job at sorting, even international & special characters. The only problem using the localeCompare() method is that "the locale and sort order used are entirely implementation dependent". In other words, when using localeCompare such as stringOne.localeCompare(stringTwo): Firefox, Safari, Chrome & IE have a different sort order for Strings.

Research on the browser-native implementations:

• http://jsbin.com/beboroyifomu/1/edit?js,console - basic latin characters comparison with localeCompare() http://jsbin.com/viyucavudela/2/ - basic latin characters comparison with localeCompare() for testing on IE8
• http://jsbin.com/beboroyifomu/2/edit?js,console - basic latin characters in string comparison : consistency check in string vs when a character is alone
• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/localeCompare - IE11+ supports the new locales & options arguments

Difficulty of "string natural sorting order"

Implementing a solid algorithm (meaning: consistent but also covering a wide range of characters) is a very tough task. UTF8 contains more than 2000 characters & covers more than 120 scripts (languages). Finally, there are some specification for this tasks, it is called the "Unicode Collation Algorithm", which can be found at http://www.unicode.org/reports/tr10/ . You can find more information about this on this question I posted https://softwareengineering.stackexchange.com/questions/257286/is-there-any-language-agnostic-specification-for-string-natural-sorting-order

Final conclusion

So considering the current level of support provided by the javascript custom implementations I came across, we will probably never see anything getting any close to supporting all this characters & scripts (languages). Hence I would rather use the browsers' native localeCompare() method. Yes, it does have the downside of beeing non-consistent across browsers but basic testing shows it covers a much wider range of characters, allowing solid & meaningful sort orders.

So as pointed out by Shog9, the answer to your question is:

return item1.attr.localeCompare(item2.attr);

Thanks to Shog9's nice answer, which put me in the "right" direction I believe

$data = array();
foreach ($request->planes as $plan) {
 $data_plan = array($plan => array('dia' => $request->dia[$plan] ) );                
 array_push($data,$data_plan);    
}
$user->planes()->sync($data);

In addition to Dee Jee solution, After trying out his solution, My error never went.

I noticed(after two days of head scratch) that the browser has cached the files improperly.

• My browser wasn't able to load the preview of the cached files and status code from express was 301.
• In the networks tab of the browser dev tools, I get that those files are server from disk cache.

Solution

Remove the cached files. By clearing the browser history in a span of 1 hour, so that all the cached files get deleted.

I just ran into the same problem today. As the previous answers indicate, the problem stems from the use of a color in the divider tag, rather than a drawable. However, instead of writing my own drawable xml, I prefer to use themed attributes as much as possible. You can use the android:attr/dividerHorizontal and android:attr/dividerVertical to get a predefined drawable instead:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:showDividers="middle"
    android:divider="?android:attr/dividerVertical"
    android:orientation="horizontal">
    <!-- other views -->
</LinearLayout>

The attributes are available in API 11 and above.

Also, as mentioned by bocekm in his answer, the dividerPadding property does NOT add extra padding on either side of a vertical divider, as one might assume. Instead it defines top and bottom padding and thus may truncate the divider if it's too large.

I've seen similar answers, but nothing exactly like what worked for me. On Linux, I had to kill and restart my gpg-agent with:

$ pkill gpg-agent
$ gpg-agent --daemon
$ git commit ...

This did the trick for me. It looks like you do need to have user.signingkey set to your private key as well from what some other comments are saying.

$ git config --global user.signingkey [your_key_hash]

java.time

Using the java.time framework built into Java 8 and later.

import java.time.LocalDate;
import java.time.ZoneId;

int year = 2011;
int month = 10;
int day = 1;
int date = LocalDate.of(year, month, day);

date.atStartOfDay(ZoneId.of("UTC")).toEpochSecond; # Long = 1317427200

const char *one = "Hello ";
const char *two = "World";

string total( string(one) + two );

// to use the concatenation as const char*, use:
total.c_str()

Updated: changed string total = string(one) + string(two); to string total( string(one) + two ); for performance reasons (avoids construction of string two and temporary string total)

// string total(move(move(string(one)) + two));  // even faster?

use

range(count)

int and float are not iterable

those icons are a way of Egit to show you status of the current file/folder in git. You might want to check this out:

• dirty (folder) - At least one file below the folder is dirty; that means that it has changes in the working tree that are neither in the index nor in the repository.
• tracked - The resource is known to the Git repository. untracked - The resource is not known to the Git repository.
• ignored - The resource is ignored by the Git team provider. Here only the preference settings under Team -> Ignored Resources and the "derived" flag are relevant. The .gitignore file is not taken into account.
• dirty - The resource has changes in the working tree that are neither in the index nor in the repository.
• staged - The resource has changes which are added to the index. Not that adding to the index is possible at the moment only on the commit dialog on the context menu of a resource.
• partially-staged - The resource has changes which are added to the index and additionally changes in the working tree that are neither in the index nor in the repository.
• added - The resource is not yet tracked by but added to the Git repository.
• removed - The resource is staged for removal from the Git repository.
• conflict - A merge conflict exists for the file.
• assume-valid - The resource has the "assume unchanged" flag. This means that Git stops checking the working tree files for possible modifications, so you need to manually unset the bit to tell Git when you change the working tree file. This setting can be switched on with the menu action Team->Assume unchanged (or on the command line with git update-index--assume-unchanged).

An excellent explanation can be found here: Generate script in SQL Server Management Studio

Courtesy Ali Issa Here's what you have to do:

1. Right click the database (not the table) and select tasks --> generate scripts
2. Next --> select the requested table/tables (from select specific database objects)
3. Next --> click advanced --> types of data to script = schema and data

If you want to create a script that just generates the tables (no data) you can skip the advanced part of the instructions!

You can specify both max post size and max file size limit in php.ini

post_max_size = 64M
upload_max_filesize = 64M

Also it's worth knowing that you may need to include .\ in front of the script name. For example:

.\scriptname.ps1

I've been using Hamid's answer for a while, but it in cases where the languages array is like ["en", "en-GB", "en-US", "fr-FR", "fr", "en-ZA"] it will return "en", when "en-GB" would be a better match.

My update (below) will return the first long format code e.g. "en-GB", otherwise it will return the first short code e.g. "en", otherwise it will return null.

I know a few users have talked about installing this and that and adding command lines programmes and downloading...

Personally I am lazy and find all these methods cumbersome and slow, plus I don't want to download anything and find the correct cmd lines if I don't have to.

Best way for me on my personal IIS server is to use RapidSSLOnline. This is a tool that's on a server allows you to upload your certificate and private key and is able to generate a pfx file for you that you can directly import into IIS.

The link is here: https://www.rapidsslonline.com/ssl-tools/ssl-converter.php

Below is the steps used for the scenario requested.

1. Select Current Type = PEM
2. Change for = PFX
3. Upload your certificate
4. Upload your private key
5. If you have ROOT CA cert or intermediate certs upload them too
6. Set a password of your choosing, used in IIS
7. Click the reCaptcha to prove you're not a bot
8. Click Convert

And that's it you should have a PFX downloaded and use this in your Import process on IIS.

Hope this helps other like minded, lazy tech people.

I think you should first define all your routes and as the last route add

//The 404 Route (ALWAYS Keep this as the last route)
app.get('*', function(req, res){
  res.status(404).send('what???');
});

An example app which does work:

app.js:

var express = require('express'),
    app = express.createServer();

app.use(express.static(__dirname + '/public'));

app.get('/', function(req, res){
  res.send('hello world');
});

//The 404 Route (ALWAYS Keep this as the last route)
app.get('*', function(req, res){
  res.send('what???', 404);
});

app.listen(3000, '127.0.0.1');

Step 1: Do File -> Import Settings... and select the settings jar file

Step 2: Go to Settings -> Editor -> Colors and Fonts to choose the theme you just installed.

Use CONCAT_WS().

SELECT CONCAT_WS(' ',firstname,lastname) as firstlast FROM users 
WHERE firstlast = "Bob Michael Jones";

The first argument is the separator for the rest of the arguments.

Asked and answered before...

Books on line says "COUNT ( { [ [ ALL | DISTINCT ] expression ] | * } )"

"1" is a non-null expression so it's the same as COUNT(*). The optimiser recognises it as trivial so gives the same plan. A PK is unique and non-null (in SQL Server at least) so COUNT(PK) = COUNT(*)

This is a similar myth to EXISTS (SELECT * ... or EXISTS (SELECT 1 ...

And see the ANSI 92 spec, section 6.5, General Rules, case 1

        a) If COUNT(*) is specified, then the result is the cardinality

          null value eliminated in set function.

In Python, lambda is a keyword used to define anonymous functions(functions with no name) and that's why they are known as lambda functions.

Basically it is used for defining anonymous functions that can/can't take argument(s) and returns value of data/expression. Let's see an example.

>>> # Defining a lambda function that takes 2 parameters(as integer) and returns their sum
... 
>>> lambda num1, num2: num1 + num2 
<function <lambda> at 0x1004b5de8>
>>> 
>>> # Let's store the returned value in variable & call it(1st way to call)
... 
>>> addition = lambda num1, num2: num1 + num2
>>> addition(62, 5)
67
>>> addition(1700, 29)
1729
>>> 
>>> # Let's call it in other way(2nd way to call, one line call )
... 
>>> (lambda num1, num2: num1 + num2)(120, 1)
121
>>> (lambda num1, num2: num1 + num2)(-68, 2)
-66
>>> (lambda num1, num2: num1 + num2)(-68, 2**3)
-60
>>> 

Now let me give an answer of your 2nd question. The 1st answer is also great. This is my own way to explain with another example.

Suppose we have a list of items(integers and strings with numeric contents) as follows,

nums = ["2", 1, 3, 4, "5", "8", "-1", "-10"]

and I want to sort it using sorted() function, lets see what happens.

>>> nums = ["2", 1, 3, 4, "5", "8", "-1", "-10"]
>>> sorted(nums)
[1, 3, 4, '-1', '-10', '2', '5', '8']
>>>

It didn't give me what I expected as I wanted like below,

['-10', '-1', 1, '2', 3, 4, '5', '8']

It means we need some strategy(so that sorted could treat our string items as an ints) to achieve this. This is why the key keyword argument is used. Please look at the below one.

>>> nums = ["2", 1, 3, 4, "5", "8", "-1", "-10"]
>>> sorted(nums, key=int)
['-10', '-1', 1, '2', 3, 4, '5', '8']
>>> 

Lets use lambda function as a value of key

>>> names = ["Rishikesh", "aman", "Ajay", "Hemkesh", "sandeep", "Darshan", "Virendra", "Shwetabh"]
>>> names2 = sorted(names)
>>> names2
['Ajay', 'Darshan', 'Hemkesh', 'Rishikesh', 'Shwetabh', 'Virendra', 'aman', 'sandeep']
>>> # But I don't want this o/p(here our intention is to treat 'a' same as 'A')
...
>>> names3 = sorted(names, key=lambda name:name.lower())
>>> names3
['Ajay', 'aman', 'Darshan', 'Hemkesh', 'Rishikesh', 'sandeep', 'Shwetabh', 'Virendra']
>>>

You can define your own function(callable) and provide it as value of key.

Dear programers, I have written the below code for you, just try to understand it and comment your explanation. I would be glad to see your explanation(it's simple).

>>> def validator(item):
...     try:
...         return int(item)
...     except:
...         return 0
... 
>>> sorted(['gurmit', "0", 5, 2, 1, "front", -2, "great"], key=validator)
[-2, 'gurmit', '0', 'front', 'great', 1, 2, 5]
>>>

I hope it would be useful.

I was struggling with a similar issue on a CentOS server. Using php artisan serv and accessing it through port 8000 on the local machine worked fine but could not get my remote machines to load a particular view. I could return strings fine, and some views were loading. Chased my tail on permissions for a while before I finally realized it was an SELinux issue. I just set it from enforce to permissive and it worked. Hope that helps someone else out there that may be encountering the same issue.

setenforce permissive

@Html.DropDownListFor(model => model.Type, Enum.GetNames(typeof(Rewards.Models.PropertyType)).Select(e => new SelectListItem { Text = e }))

I really like the @mgilson comment, since if you have a two iterables, one that corresponds to the keys and the other the values, you can also do the following.

keys = ['a', 'b', 'c']
values = [1, 2, 3]
d = dict(zip(keys, values))

giving

d = {'a': 1, 'b': 2, 'c': 3}

Depending on how many dynamic classes you need to add as your project grows it's probably worth checking out the classnames utility by JedWatson on GitHub. It allows you to represent your conditional classes as an object and returns those that evaluate to true.

So as an example from its React documentation:

render () {

var btnClass = classNames({
  'btn': true,
  'btn-pressed': this.state.isPressed,
  'btn-over': !this.state.isPressed && this.state.isHovered
});

return <button className={btnClass}>I'm a button!</button>;

} 

Since React triggers a re-render when there is a state change, your dynamic class names are handled naturally and kept up to date with the state of your component.

Here are both fixes.

First, regarding the fixed sidebar, you need to give it a height for it to overflow:

HTML Code:

<div id="sidebar">Menu</div>
<div id="content">Text</div>

CSS Code:

body {font:76%/150% Arial, Helvetica, sans-serif; color:#666; width:100%; height:100%;}
#sidebar {position:fixed; top:0; left:0; width:20%; height:100%; background:#EEE; overflow:auto;}
#content {width:80%; padding-left:20%;}

@media screen and (max-height:200px){
    #sidebar {color:blue; font-size:50%;}
}

Live example: http://jsfiddle.net/RWxGX/3/

It's impossible NOT to get a scroll bar if your content overflows the height of the div. That's why I've added a media query for screen height. Maybe you can adjust your styles for short screen sizes so the scroll doesn't need to appear.

In my case, I found (after much hair-pulling) that the "pending" status was caused by the AdBlock extension. The image that I couldn't get to load had the word "ad" in the URL, so AdBlock kept it from loading.

Disabling AdBlock fixes this issue.

Renaming the file so that it doesn't contain "ad" in the URL also fixes it, and is obviously a better solution. Unless it's an advertisement, in which case you should leave it like that. :)

So if the issue is you just created a website and your clients or any given ISP DNS is cached and doesn't show new site yet. Yes all the other stuff applies ipconfig reset browser etc. BUT here's an Idea and something I do from time to time. You can set an alternate network ISP's DNS in the tcpip properties on the NIC properties. So if your ISP is say telstra and it hasn't propagated or updated you can specify an alternate service providers dns there. if that isp dns is updated before your native one hey presto you will see new site.But there is lots of other tricks you can do to determine propagation and get mail to work prior to the DNS updating. drop me a line if any one wants to chat.

You can actually put anything inside a toolbar. See the below code.

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentStart="true"
        android:background="@color/colorPrimary">

</android.support.v7.widget.Toolbar>

Between the above toolbar tag you can put almost anything. That is the benefit of using a Toolbar.

Use the join method from the Array type.

a.value = [a, b, c, d, e, f];
var stringValueYouWant = a.join();

The join method will return a string that is the concatenation of all the array elements. It will use the first parameter you pass as a separator - if you don't use one, it will use the default separator, which is the comma.

Here's an answer regarding the XML configuration, note that if you don't give the file appender a ConversionPattern it will create 0 byte file and not write anything:

try this: objectId.str;

see doc.

Not all attributes of an object are meant to be directly set from outside the class. Having writers for all your instance variables is generally a sign of weak encapsulation and a warning that you're introducing too much coupling between your classes.

As a practical example: I wrote a design program where you put items inside containers. The item had attr_reader :container, but it didn't make sense to offer a writer, since the only time the item's container should change is when it's placed in a new one, which also requires positioning information.

If you want auto-indent just like Emacs does it on TAB, i.e. indent the current line and move the cursor to the first non-whitespace character, do this:

1. Go to Tools -> Options -> Editor -> Macros
2. Create a new macro and call it something like "tabindent"

3. Insert the following macro code:

   reindent-line caret-line-first-column caret-begin-line

4. Click "Set Shortcut" and press TAB

conda create -n py37 -c anaconda anaconda=5.3

seems to be working.

more elegant solution is to use && (using NgFor and its first, its free to use ur own matching tho):

    <div 
        *ngFor="let day of days;
                let first = first;"
        class="day"
        [ngClass]="first && ('day--' + day)"
    </div>

will turn out as:

class="day day--monday"

As posted in my earlier answer

Use below code :

TelephonyManager tMgr = (TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();

In AndroidManifest.xml, give the following permission:

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

But remember, this code does not always work, since Cell phone number is dependent on the SIM Card and the Network operator / Cell phone carrier.

Also, try checking in Phone--> Settings --> About --> Phone Identity, If you are able to view the Number there, the probability of getting the phone number from above code is higher. If you are not able to view the phone number in the settings, then you won't be able to get via this code!

Suggested Workaround:

1. Get the user's phone number as manual input from the user.
2. Send a code to the user's mobile number via SMS.
3. Ask user to enter the code to confirm the phone number.
4. Save the number in sharedpreference.

Do the above 4 steps as one time activity during the app's first launch. Later on, whenever phone number is required, use the value available in shared preference.

you can use this for making a list Unique

ArrayList<String> listWithDuplicateValues = new ArrayList<>();
list.add("first");
list.add("first");
list.add("second");

ArrayList uniqueList = (ArrayList) listWithDuplicateValues.stream().distinct().collect(Collectors.toList());

I found the solution.

As said in the EDIT of my answer, a <div> is misfunctioning in a <table>. So I wrote this code instead :

<tr id="hidden" style="display:none;">
    <td class="depot_table_left">
        <label for="sexe">Sexe</label>
    </td>
    <td>
        <select type="text" name="sexe">
            <option value="1">Sexe</option>
            <option value="2">Joueur</option>
            <option value="3">Joueuse</option>
        </select>
    </td>
</tr>

And this is working fine.

Thanks everybody ;)

You need to reload the entity after saving changes. Because it has been altered by a database trigger which cannot be tracked by EF. SO we need to reload the entity again from the DB,

db.Entry(MyNewObject).GetDatabaseValues();

Then

int id = myNewObject.Id;

Look at @jayantha answer in below question:

How can I get Id of the inserted entity in Entity framework when using defaultValue?

Looking @christian answer in below question may help too:

Entity Framework Refresh context?

You need something like a full outer join. System.Linq.Enumerable has no method that implements a full outer join, so we have to do it ourselves.

var dict1 = list1.ToDictionary(l1 => l1.Name);
var dict2 = list2.ToDictionary(l2 => l2.Name);
    //get the full list of names.
var names = dict1.Keys.Union(dict2.Keys).ToList();
    //produce results
var result = names
.Select( name =>
{
  Person p1 = dict1.ContainsKey(name) ? dict1[name] : null;
  Person p2 = dict2.ContainsKey(name) ? dict2[name] : null;
      //left only
  if (p2 == null)
  {
    p1.Change = 0;
    return p1;
  }
      //right only
  if (p1 == null)
  {
    p2.Change = 0;
    return p2;
  }
      //both
  p2.Change = p2.Value - p1.Value;
  return p2;
}).ToList();

I think you can archive that by add multiple layout resource for each screen size, example:

res/layout/my_layout.xml             // layout for normal screen size ("default")
res/layout-small/my_layout.xml       // layout for small screen size with small text
res/layout-large/my_layout.xml       // layout for large screen size with larger text
res/layout-xlarge/my_layout.xml      // layout for extra large screen size with even larger text
res/layout-xlarge-land/my_layout.xml // layout for extra large in landscape orientation

Reference: 1.http://developer.android.com/guide/practices/screens_support.html

If I understand correctly, you assumed that -v is the "print version" command. Check the documentation, that is not the case -- instead ant -v is running ant build in verbose mode. So ant is trying to perform your build, based on the build.xml file, which is obviously not there.

To answer your question explicitly: there is probably nothing wrong with both the system nor ant installation.

Schema says what tables are in database, what columns they have and how they are related. Each database has its own schema.

Real programmers do it with semaphores.

Have a variable set to 0. Increment it before each AJAX call. Decrement it in each success handler, and test for 0. If it is, you're done.

I do it this way...

public static function multiExplode($delims, $string, $special = '|||') {

    if (is_array($delims) == false) {
        $delims = array($delims);
    }

    if (empty($delims) == false) {
        foreach ($delims as $d) {
            $string = str_replace($d, $special, $string);
        }
    }

    return explode($special, $string);
}

I faced the same problem while installing Eclipse for c/c++ applications .I downloaded Mingw GCC ,put its bin folder in your path ,used it in toolchains while making new C++ project in Eclipse and build which solved my problem. Referred to this video

Although currently there is no way to declare a method or property as private, ES6 modules are not in the global namespace. Therefore, anything that you declare in your module and do not export will not be available to any other part of your program, but will still be available to your module during run time. Thus, you have private properties and methods :)

Here is an example (in test.js file)

function tryMe1(a) {
  console.log(a + 2);
}

var tryMe2 = 1234;

class myModule {
  tryMe3(a) {
    console.log(a + 100);
  }

  getTryMe1(a) {
    tryMe1(a);
  }

  getTryMe2() {
    return tryMe2;
  }
}

// Exports just myModule class. Not anything outside of it.
export default myModule; 

In another file

import MyModule from './test';

let bar = new MyModule();

tryMe1(1); // ReferenceError: tryMe1 is not defined
tryMe2; // ReferenceError: tryMe2 is not defined
bar.tryMe1(1); // TypeError: bar.tryMe1 is not a function
bar.tryMe2; // undefined

bar.tryMe3(1); // 101
bar.getTryMe1(1); // 3
bar.getTryMe2(); // 1234

If you don't want a terminal window to pop up when you run your program, use pythonw.exe;
Otherwise, use python.exe

Regarding the syntax error: print is now a function in 3.x
So use instead:

print("a")

You can create a temp table variable and insert the data into it, then insert the data into your actual table by selecting it from the temp table.

 declare @TableVar table 
 (
    firstCol varchar(50) NOT NULL,
    secondCol varchar(50) NOT NULL
 )

BULK INSERT @TableVar FROM 'PathToCSVFile' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')
GO

INSERT INTO dbo.ExistingTable
(
    firstCol,
    secondCol
)
SELECT firstCol,
       secondCol
FROM @TableVar

GO

Because the model that gets posted to the WebApi controller is detached from any entity-framework (EF) context, the only option is to load the object graph (parent including its children) from the database and compare which children have been added, deleted or updated. (Unless you would track the changes with your own tracking mechanism during the detached state (in the browser or wherever) which in my opinion is more complex than the following.) It could look like this:

public void Update(UpdateParentModel model)
{
    var existingParent = _dbContext.Parents
        .Where(p => p.Id == model.Id)
        .Include(p => p.Children)
        .SingleOrDefault();

    if (existingParent != null)
    {
        // Update parent
        _dbContext.Entry(existingParent).CurrentValues.SetValues(model);

        // Delete children
        foreach (var existingChild in existingParent.Children.ToList())
        {
            if (!model.Children.Any(c => c.Id == existingChild.Id))
                _dbContext.Children.Remove(existingChild);
        }

        // Update and Insert children
        foreach (var childModel in model.Children)
        {
            var existingChild = existingParent.Children
                .Where(c => c.Id == childModel.Id && c.Id != default(int))
                .SingleOrDefault();

            if (existingChild != null)
                // Update child
                _dbContext.Entry(existingChild).CurrentValues.SetValues(childModel);
            else
            {
                // Insert child
                var newChild = new Child
                {
                    Data = childModel.Data,
                    //...
                };
                existingParent.Children.Add(newChild);
            }
        }

        _dbContext.SaveChanges();
    }
}

...CurrentValues.SetValues can take any object and maps property values to the attached entity based on the property name. If the property names in your model are different from the names in the entity you can't use this method and must assign the values one by one.

ObjectFactory fact = new ObjectFactory();   
JAXBElement<String> str = fact.createCompositeTypeStringValue("vik");    
comp.setStringValue(str);
CompositeType retcomp = service.getDataUsingDataContract(comp);
System.out.println(retcomp.getStringValue().getValue());

Threads within the same process share the Memory, but each thread has its own stack and registers, and threads store thread-specific data in the heap. Threads never execute independently, so the inter-thread communication is much faster when compared to inter-process communication.

Processes never share the same memory. When a child process creates it duplicates the memory location of the parent process. Process communication is done by using pipe, shared memory, and message parsing. Context switching between threads is very slow.

Although probably not exactly what your looking for and you probably don't care at this point since the question was asked 5 years ago, one method is to use "forward".

Go to your inbox or wherever your messages are and select the 2+ messages you want to send than simply click forward... all messages get combined into 1.

The solution for your question is:

public static void restartActivity(Activity act){
    Intent intent=new Intent();
    intent.setClass(act, act.getClass());
    ((Activity)act).startActivity(intent);
    ((Activity)act).finish();
}

You need to cast to activity context to start new activity and as well as to finish the current activity.

Hope this helpful..and works for me.

You can also try using this line if the other doesn't work:

du -sh /var/lib/mysql/database_Name

You may also want to check with your host and see how big they allow your databases to be.

NumPy is slower because it casts the input to boolean values (so None and 0 becomes False and everything else becomes True).

import pandas as pd
import numpy as np
s = pd.Series([True, None, False, True])
np.logical_not(s)

gives you

0    False
1     True
2     True
3    False
dtype: object

whereas ~s would crash. In most cases tilde would be a safer choice than NumPy.

Pandas 0.25, NumPy 1.17

Maybe this is what you searched for :

function data() {
    // your code
    return $array; 
}
$var = data(); 
foreach($var as $value) {
    echo $value; 
}

Try this code refer from here

Honestly the easiest way was to add file hosting to the server.

• Open IIS

• Add a Virtual Directory under Default Web Site

  • virtual path will be what you want to browse to in the browser. So if you choose "serverName/images you will be able to browse to it by going to http://serverName/images
  • Then add the physical path on the C: drive

• Add the appropriate permissions to the folder on the C: drive for "NETWORK SERVICE" and "IIS AppPool\DefaultAppPool"

• Refresh Default Web Site

• And you're done. You can now browse to any image in that folder by navigating to http://yourServerName/whateverYourFolderNameIs/yourImage.jpg and use that url in your img src

Hope this helps someone

public enum NewEnum {
   ONE("test"),
   TWO("test");

   private String s;

   private NewEnum(String s) {
      this.s = s);
   }

    public String getS() {
        return this.s;
    }
}

For example, you can define a layout file which contains a EditText element.

<?xml version="1.0" encoding="utf-8"?>
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/searchfield"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:inputType="textFilter" >

</EditText> 

you can do

public class MainActivity extends Activity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ActionBar actionBar = getActionBar();
    // add the custom view to the action bar
    actionBar.setCustomView(R.layout.actionbar_view);
    EditText search = (EditText) actionBar.getCustomView().findViewById(R.id.searchfield);
    search.setOnEditorActionListener(new OnEditorActionListener() {

      @Override
      public boolean onEditorAction(TextView v, int actionId,
          KeyEvent event) {
        Toast.makeText(MainActivity.this, "Search triggered",
            Toast.LENGTH_LONG).show();
        return false;
      }
    });
    actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM
        | ActionBar.DISPLAY_SHOW_HOME);


    }

If you want to get whole response in JSON format, try this:

I have tried a new way to get whole response from server in JSON format without creating any model class. I am not using any model class to get data from server because I don't know what response I will get or it may change according to requirements.

this is JSON response:

{"contacts": [
    {
        "id": "c200",
        "name": "sunil",
        "email": "[email protected]",
        "address": "xx-xx-xxxx,x - street, x - country",
        "gender" : "male",
        "phone": {
            "mobile": "+91 0000000000",
            "home": "00 000000",
            "office": "00 000000"
        }
    },
    {
        "id": "c201",
        "name": "Johnny Depp",
        "email": "[email protected]",
        "address": "xx-xx-xxxx,x - street, x - country",
        "gender" : "male",
        "phone": {
            "mobile": "+91 0000000000",
            "home": "00 000000",
            "office": "00 000000"
        }
    },
    .
    .
    .
]}

1. In your API interface change the parameter

   public interface ApiInterface {
   @POST("/index.php/User/login")//your api link 
   @FormUrlEncoded
   Call<Object> getmovies(@Field("user_email_address") String title,
                   @Field("user_password") String body);
   }
   

2. in your main activity where you are calling this

   ApiInterface apiService =
           ApiClient.getClient().create(ApiInterface.class);
   
   Call call = apiService.getmovies("[email protected]","123456");
   call.enqueue(new Callback() {
       @Override
       public void onResponse(Call call, Response response) {
           Log.e("TAG", "response 33: "+new Gson().toJson(response.body()) );
       }
   
       @Override
       public void onFailure(Call call, Throwable t) {
           Log.e("TAG", "onFailure: "+t.toString() );
           // Log error here since request failed
       }
   });
   

3. after that you can normally get parameter using JSON object and JSON array

Output

SQL Server returns messages after a batch of statements has been executed. Normally, you'd use SQL GO to indicate the end of a batch and to retrieve the results:

PRINT '1'
GO

WAITFOR DELAY '00:00:05'

PRINT '2'
GO

WAITFOR DELAY '00:00:05'

PRINT '3'
GO

In this case, however, the print statement you want returned immediately is in the middle of a loop, so the print statements cannot be in their own batch. The only command I know of that will return in the middle of a batch is RAISERROR (...) WITH NOWAIT, which gbn has provided as an answer as I type this.

Just as example from github, it works. https://github.com/eligrey/FileSaver.js

<script src="FileSaver.js"></script>
<script type="text/javascript">
    var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
    saveAs(blob, "hello world.txt");
</script>

One easy way is to drag and drop. It will copy files to /sdcard/Download. You can copy whole folders or multiple files. Make sure that "Enable Clipboard Sharing" is enabled. (under ...->Settings)

3 Steps you can follow

1. chmod -R 775 <repo path>  
   ---> change permissions of repository
   

2. chown -R apache:apache <repo path>  
   ---> change owner of svn repository
   

3. chcon -R -t httpd_sys_content_t <repo path>  
   ----> change SELinux security context of the svn repository
   

There are a number of ways to make Python speak in both Python3 and Python2, two great methods are:

• Using os

If you are on mac you will have the os module built into your computer. You can import the os module using:

import os

You can then use os to run terminal commands using the os.system command:

os.system("Your terminal")

In terminal, the way you make your computer speak is using the "say" command, thus to make the computer speak you simply use:

os.system("say 'some text'")

If you want to use this to speak a variable you can use:

os.system("say " + myVariable)

The second way to get python to speak is to use

• The pyttsx module

You will have to install this using

pip isntall pyttsx3

or for Python3

pip3 install pyttsx3

You can then use the following code to get it to speak:

import pyttsx3
engine = pyttsx3.init()

engine.say("Your Text")

engine.runAndWait()

I hope this helps! :)

If you need a custom string sort, you can create a function that returns a number based on the order you specify.

For example, I had pictures that I wanted to sort based on being front side or clasp. So I did the following:

Private Function sortpictures(s As String) As Integer
    If Regex.IsMatch(s, "FRONT") Then
        Return 0
    ElseIf Regex.IsMatch(s, "SIDE") Then
        Return 1
    ElseIf Regex.IsMatch(s, "CLASP") Then
        Return 2
    Else
        Return 3
    End If
End Function

Then I call the sort function like this:

list.Sort(Function(elA As String, elB As String)
                  Return sortpictures(elA).CompareTo(sortpictures(elB))
              End Function)

After trying everything I could find and nothing worked, I just tried this:

touch ~/.bash_profile; open ~/.bash_profile

Inside the file added this line.

export PATH="$PATH:/usr/local/Cellar/openssl/1.0.2j/bin/openssl"

now it works :)

Jorns-iMac:~ jorn$ openssl version -a
OpenSSL 1.0.2j  26 Sep 2016

Though I am very late in this discussion, I thought this may be useful for some one in future.

I had faced similar situation. The easiest workaround for those who doesn't mind unsetting and resetting the variable is to do so. I am pretty sure the reason why this is not working is clear from the other answers and from the php.net manual. The simplest workaround worked for me is

Assumption:

1. $object is the object with overloaded __get and __set from the base class, which I am not in the freedom to modify.
2. shippingData is the array I want to modify a field of for e.g. :- phone_number

// First store the array in a local variable.
$tempShippingData = $object->shippingData;

unset($object->shippingData);

$tempShippingData['phone_number'] = '888-666-0000' // what ever the value you want to set

$object->shippingData = $tempShippingData; // this will again call the __set and set the array variable

unset($tempShippingData);

Note: this solution is one of the quick workaround possible to solve the problem and get the variable copied. If the array is too humungous, it may be good to force rewrite the __get method to return a reference rather expensive copying of big arrays.

Try to add in .vimrc

[OOT]

A bit OOT, but this question is the most closest topic with my question.

Here is an example if you want to show Event where ALL participant meet certain requirement. Let's say, event where ALL the participant has fully paid. So, it WILL NOT return events which having one or more participants that haven't fully paid .

Simply use the whereDoesntHave of the others 2 statuses.

Let's say the statuses are haven't paid at all [eq:1], paid some of it [eq:2], and fully paid [eq:3]

Event::whereDoesntHave('participants', function ($query) {
   return $query->whereRaw('payment = 1 or payment = 2');
})->get();

In my case, I was updating the server-sided datatable twice and it gives me this error. Hope it helps someone.

Check out the "--only-keep-debug" option of the strip command.

From the link:

The intention is that this option will be used in conjunction with --add-gnu-debuglink to create a two part executable. One a stripped binary which will occupy less space in RAM and in a distribution and the second a debugging information file which is only needed if debugging abilities are required.

Use a regular expression, if your script implementation supports them. Something like:

myString.replace(/[^0-9]/g, '');

Mockito matchers are static methods and calls to those methods, which stand in for arguments during calls to when and verify.

Hamcrest matchers (archived version) (or Hamcrest-style matchers) are stateless, general-purpose object instances that implement Matcher<T> and expose a method matches(T) that returns true if the object matches the Matcher's criteria. They are intended to be free of side effects, and are generally used in assertions such as the one below.

/* Mockito */  verify(foo).setPowerLevel(gt(9000));
/* Hamcrest */ assertThat(foo.getPowerLevel(), is(greaterThan(9000)));

Mockito matchers exist, separate from Hamcrest-style matchers, so that descriptions of matching expressions fit directly into method invocations: Mockito matchers return T where Hamcrest matcher methods return Matcher objects (of type Matcher<T>).

Mockito matchers are invoked through static methods such as eq, any, gt, and startsWith on org.mockito.Matchers and org.mockito.AdditionalMatchers. There are also adapters, which have changed across Mockito versions:

• For Mockito 1.x, Matchers featured some calls (such as intThat or argThat) are Mockito matchers that directly accept Hamcrest matchers as parameters. ArgumentMatcher<T> extended org.hamcrest.Matcher<T>, which was used in the internal Hamcrest representation and was a Hamcrest matcher base class instead of any sort of Mockito matcher.
• For Mockito 2.0+, Mockito no longer has a direct dependency on Hamcrest. Matchers calls phrased as intThat or argThat wrap ArgumentMatcher<T> objects that no longer implement org.hamcrest.Matcher<T> but are used in similar ways. Hamcrest adapters such as argThat and intThat are still available, but have moved to MockitoHamcrest instead.

Regardless of whether the matchers are Hamcrest or simply Hamcrest-style, they can be adapted like so:

/* Mockito matcher intThat adapting Hamcrest-style matcher is(greaterThan(...)) */
verify(foo).setPowerLevel(intThat(is(greaterThan(9000))));

In the above statement: foo.setPowerLevel is a method that accepts an int. is(greaterThan(9000)) returns a Matcher<Integer>, which wouldn't work as a setPowerLevel argument. The Mockito matcher intThat wraps that Hamcrest-style Matcher and returns an int so it can appear as an argument; Mockito matchers like gt(9000) would wrap that entire expression into a single call, as in the first line of example code.

What matchers do/return

when(foo.quux(3, 5)).thenReturn(true);

When not using argument matchers, Mockito records your argument values and compares them with their equals methods.

when(foo.quux(eq(3), eq(5))).thenReturn(true);    // same as above
when(foo.quux(anyInt(), gt(5))).thenReturn(true); // this one's different

When you call a matcher like any or gt (greater than), Mockito stores a matcher object that causes Mockito to skip that equality check and apply your match of choice. In the case of argumentCaptor.capture() it stores a matcher that saves its argument instead for later inspection.

Matchers return dummy values such as zero, empty collections, or null. Mockito tries to return a safe, appropriate dummy value, like 0 for anyInt() or any(Integer.class) or an empty List<String> for anyListOf(String.class). Because of type erasure, though, Mockito lacks type information to return any value but null for any() or argThat(...), which can cause a NullPointerException if trying to "auto-unbox" a null primitive value.

Matchers like eq and gt take parameter values; ideally, these values should be computed before the stubbing/verification starts. Calling a mock in the middle of mocking another call can interfere with stubbing.

Matcher methods can't be used as return values; there is no way to phrase thenReturn(anyInt()) or thenReturn(any(Foo.class)) in Mockito, for instance. Mockito needs to know exactly which instance to return in stubbing calls, and will not choose an arbitrary return value for you.

Implementation details

Matchers are stored (as Hamcrest-style object matchers) in a stack contained in a class called ArgumentMatcherStorage. MockitoCore and Matchers each own a ThreadSafeMockingProgress instance, which statically contains a ThreadLocal holding MockingProgress instances. It's this MockingProgressImpl that holds a concrete ArgumentMatcherStorageImpl. Consequently, mock and matcher state is static but thread-scoped consistently between the Mockito and Matchers classes.

Most matcher calls only add to this stack, with an exception for matchers like and, or, and not. This perfectly corresponds to (and relies on) the evaluation order of Java, which evaluates arguments left-to-right before invoking a method:

when(foo.quux(anyInt(), and(gt(10), lt(20)))).thenReturn(true);
[6]      [5]  [1]       [4] [2]     [3]

This will:

1. Add anyInt() to the stack.
2. Add gt(10) to the stack.
3. Add lt(20) to the stack.
4. Remove gt(10) and lt(20) and add and(gt(10), lt(20)).
5. Call foo.quux(0, 0), which (unless otherwise stubbed) returns the default value false. Internally Mockito marks quux(int, int) as the most recent call.
6. Call when(false), which discards its argument and prepares to stub method quux(int, int) identified in 5. The only two valid states are with stack length 0 (equality) or 2 (matchers), and there are two matchers on the stack (steps 1 and 4), so Mockito stubs the method with an any() matcher for its first argument and and(gt(10), lt(20)) for its second argument and clears the stack.

This demonstrates a few rules:

• Mockito can't tell the difference between quux(anyInt(), 0) and quux(0, anyInt()). They both look like a call to quux(0, 0) with one int matcher on the stack. Consequently, if you use one matcher, you have to match all arguments.

• Call order isn't just important, it's what makes this all work. Extracting matchers to variables generally doesn't work, because it usually changes the call order. Extracting matchers to methods, however, works great.

  int between10And20 = and(gt(10), lt(20));
  /* BAD */ when(foo.quux(anyInt(), between10And20)).thenReturn(true);
  // Mockito sees the stack as the opposite: and(gt(10), lt(20)), anyInt().
  
  public static int anyIntBetween10And20() { return and(gt(10), lt(20)); }
  /* OK */  when(foo.quux(anyInt(), anyIntBetween10And20())).thenReturn(true);
  // The helper method calls the matcher methods in the right order.
  

• The stack changes often enough that Mockito can't police it very carefully. It can only check the stack when you interact with Mockito or a mock, and has to accept matchers without knowing whether they're used immediately or abandoned accidentally. In theory, the stack should always be empty outside of a call to when or verify, but Mockito can't check that automatically. You can check manually with Mockito.validateMockitoUsage().

• In a call to when, Mockito actually calls the method in question, which will throw an exception if you've stubbed the method to throw an exception (or require non-zero or non-null values). doReturn and doAnswer (etc) do not invoke the actual method and are often a useful alternative.

• If you had called a mock method in the middle of stubbing (e.g. to calculate an answer for an eq matcher), Mockito would check the stack length against that call instead, and likely fail.

• If you try to do something bad, like stubbing/verifying a final method, Mockito will call the real method and also leave extra matchers on the stack. The final method call may not throw an exception, but you may get an InvalidUseOfMatchersException from the stray matchers when you next interact with a mock.

Common problems

• InvalidUseOfMatchersException:

  • Check that every single argument has exactly one matcher call, if you use matchers at all, and that you haven't used a matcher outside of a when or verify call. Matchers should never be used as stubbed return values or fields/variables.

  • Check that you're not calling a mock as a part of providing a matcher argument.

  • Check that you're not trying to stub/verify a final method with a matcher. It's a great way to leave a matcher on the stack, and unless your final method throws an exception, this might be the only time you realize the method you're mocking is final.

• NullPointerException with primitive arguments: (Integer) any() returns null while any(Integer.class) returns 0; this can cause a NullPointerException if you're expecting an int instead of an Integer. In any case, prefer anyInt(), which will return zero and also skip the auto-boxing step.

• NullPointerException or other exceptions: Calls to when(foo.bar(any())).thenReturn(baz) will actually call foo.bar(null), which you might have stubbed to throw an exception when receiving a null argument. Switching to doReturn(baz).when(foo).bar(any()) skips the stubbed behavior.

General troubleshooting

• Use MockitoJUnitRunner, or explicitly call validateMockitoUsage in your tearDown or @After method (which the runner would do for you automatically). This will help determine whether you've misused matchers.

• For debugging purposes, add calls to validateMockitoUsage in your code directly. This will throw if you have anything on the stack, which is a good warning of a bad symptom.

This answer is not for DevOps/ system admin guys, but for them who are using IDE like eclipse and facing invalid LOC header (bad signature) issue.

You can force update the maven dependencies, as follows:

You can also use query scopes to make things a bit tidier, so you can do something like:

Invoice::where('account', 27)->notPaidAt($date)->get();

Then in your model

public function scopeNotPaidAt($query, $asAt)
{
    $query = $query->where(function ($query) use ($asAt) { 
        $query->where('paid', '=', '0000-00-00')->orWhere('paid', '>=', $asAt); 
    });
    return $query;    
}

Here's an example of code which uses the UTL_FILE.PUT and UTL_FILE.PUT_LINE calls:

declare 
  fHandle  UTL_FILE.FILE_TYPE;
begin
  fHandle := UTL_FILE.FOPEN('my_directory', 'test_file', 'w');

  UTL_FILE.PUT(fHandle, 'This is the first line');
  UTL_FILE.PUT(fHandle, 'This is the second line');
  UTL_FILE.PUT_LINE(fHandle, 'This is the third line');

  UTL_FILE.FCLOSE(fHandle);
EXCEPTION
  WHEN OTHERS THEN
    DBMS_OUTPUT.PUT_LINE('Exception: SQLCODE=' || SQLCODE || '  SQLERRM=' || SQLERRM);
    RAISE;
end;

The output from this looks like:

This is the first lineThis is the second lineThis is the third line

I think you set the marquee width related to 5 images total width. It works fine

ex: <marquee style="width:700px"></marquee>

You can't do this yourself since Java doesn't permit operator overloading.

With one exception, however. + and += are overloaded for String objects.

To get Single/Multiple values without regular expression

// For Single
var value = inputString.Split("<tag1>", '</tag1>')[1];

// For Multiple
var values = inputString.Split("<tag1>", '</tag1>').Where((_, index) => index % 2 != 0);

Interesting that these answers utilize printf like it is a given. printf converts the integer to a Hexadecimal string value.

//*************************************************************
// void prntnum(unsigned long n, int base, char sign, char *outbuf)
// unsigned long num = number to be printed
// int base        = number base for conversion;  decimal=10,hex=16
// char sign       = signed or unsigned output
// char *outbuf   = buffer to hold the output number
//*************************************************************

void prntnum(unsigned long n, int base, char sign, char *outbuf)
{

    int i = 12;
    int j = 0;

    do{
        outbuf[i] = "0123456789ABCDEF"[num % base];
        i--;
        n = num/base;
    }while( num > 0);

    if(sign != ' '){
        outbuf[0] = sign;
        ++j;
    }

    while( ++i < 13){
       outbuf[j++] = outbuf[i];
    }

    outbuf[j] = 0;

}

The add_subplot() method has several call signatures:

1. add_subplot(nrows, ncols, index, **kwargs)
2. add_subplot(pos, **kwargs)
3. add_subplot(ax)
4. add_subplot() <-- since 3.1.0

Calls 1 and 2:

Calls 1 and 2 achieve the same thing as one another (up to a limit, explained below). Think of them as first specifying the grid layout with their first 2 numbers (2x2, 1x8, 3x4, etc), e.g:

f.add_subplot(3,4,1) 
# is equivalent to:
f.add_subplot(341)

Both produce a subplot arrangement of (3 x 4 = 12) subplots in 3 rows and 4 columns. The third number in each call indicates which axis object to return, starting from 1 at the top left, increasing to the right.

This code illustrates the limitations of using call 2:

#!/usr/bin/env python3
import matplotlib.pyplot as plt

def plot_and_text(axis, text):
  '''Simple function to add a straight line
  and text to an axis object'''
  axis.plot([0,1],[0,1])
  axis.text(0.02, 0.9, text)

f = plt.figure()
f2 = plt.figure()

_max = 12
for i in range(_max):
  axis = f.add_subplot(3,4,i+1, fc=(0,0,0,i/(_max*2)), xticks=[], yticks=[])
  plot_and_text(axis,chr(i+97) + ') ' + '3,4,' +str(i+1))

  # If this check isn't in place, a 
  # ValueError: num must be 1 <= num <= 15, not 0 is raised
  if i < 9:
    axis = f2.add_subplot(341+i, fc=(0,0,0,i/(_max*2)), xticks=[], yticks=[])
    plot_and_text(axis,chr(i+97) + ') ' + str(341+i))

f.tight_layout()
f2.tight_layout()
plt.show()

You can see with call 1 on the LHS you can return any axis object, however with call 2 on the RHS you can only return up to index = 9 rendering subplots j), k), and l) inaccessible using this call.

I.e it illustrates this point from the documentation:

pos is a three digit integer, where the first digit is the number of rows, the second the number of columns, and the third the index of the subplot. i.e. fig.add_subplot(235) is the same as fig.add_subplot(2, 3, 5). Note that all integers must be less than 10 for this form to work.

Call 3

In rare circumstances, add_subplot may be called with a single argument, a subplot axes instance already created in the present figure but not in the figure's list of axes.

Call 4 (since 3.1.0):

If no positional arguments are passed, defaults to (1, 1, 1).

i.e., reproducing the call fig.add_subplot(111) in the question.

You can (but don't need to because the ViewHolder class is not static) create field context as is shown below:

private final Context context;

public MyViewHolder(View itemView) {
    super(itemView);
    context = itemView.getContext();
    ...
}

and on your onClick method just call sth like below:

@Override
public void onClick(View v) {          

    final Intent intent;
    switch (getAdapterPostion()){
        case 0:
           intent =  new Intent(context, FirstActivity.class);
           break;

        case 1:
            intent =  new Intent(context, SecondActivity.class);
            break;
           ...
        default:
           intent =  new Intent(context, DefaultActivity.class);
           break;
     }
    context.startActivity(intent);
}

or

@Override
public void onClick(View v) {          

    final Intent intent;
    if (getAdapterPosition() == sth){
       intent =  new Intent(context, OneActivity.class);
    } else if (getPosition() == sth2){
       intent =  new Intent(context, SecondActivity.class);
    } else {
       intent =  new Intent(context, DifferentActivity.class);
    }
    context.startActivity(intent);
}

Simple python code for separating the digits in string

  s="rollnumber99mixedin447"
  list(filter(lambda c: c >= '0' and c <= '9', [x for x in s]))

You can do it like this:

$firstday = date_create()->modify('first day January 2010');

EXISTS will tell you whether a query returned any results. e.g.:

SELECT * 
FROM Orders o 
WHERE EXISTS (
    SELECT * 
    FROM Products p 
    WHERE p.ProductNumber = o.ProductNumber)

IN is used to compare one value to several, and can use literal values, like this:

SELECT * 
FROM Orders 
WHERE ProductNumber IN (1, 10, 100)

You can also use query results with the IN clause, like this:

SELECT * 
FROM Orders 
WHERE ProductNumber IN (
    SELECT ProductNumber 
    FROM Products 
    WHERE ProductInventoryQuantity > 0)

>>> response='bababa'
...  if "K" in response.text:
...     raise ValueError("Not found")

Look in HTML output for actual client ID

You need to look in the generated HTML output to find out the right client ID. Open the page in browser, do a rightclick and View Source. Locate the HTML representation of the JSF component of interest and take its id as client ID. You can use it in an absolute or relative way depending on the current naming container. See following chapter.

Note: if it happens to contain iteration index like :0:, :1:, etc (because it's inside an iterating component), then you need to realize that updating a specific iteration round is not always supported. See bottom of answer for more detail on that.

Memorize NamingContainer components and always give them a fixed ID

If a component which you'd like to reference by ajax process/execute/update/render is inside the same NamingContainer parent, then just reference its own ID.

<h:form id="form">
    <p:commandLink update="result"> <!-- OK! -->
    <h:panelGroup id="result" />
</h:form>

If it's not inside the same NamingContainer, then you need to reference it using an absolute client ID. An absolute client ID starts with the NamingContainer separator character, which is by default :.

<h:form id="form">
    <p:commandLink update="result"> <!-- FAIL! -->
</h:form>
<h:panelGroup id="result" />

<h:form id="form">
    <p:commandLink update=":result"> <!-- OK! -->
</h:form>
<h:panelGroup id="result" />

<h:form id="form">
    <p:commandLink update=":result"> <!-- FAIL! -->
</h:form>
<h:form id="otherform">
    <h:panelGroup id="result" />
</h:form>

<h:form id="form">
    <p:commandLink update=":otherform:result"> <!-- OK! -->
</h:form>
<h:form id="otherform">
    <h:panelGroup id="result" />
</h:form>

NamingContainer components are for example <h:form>, <h:dataTable>, <p:tabView>, <cc:implementation> (thus, all composite components), etc. You recognize them easily by looking at the generated HTML output, their ID will be prepended to the generated client ID of all child components. Note that when they don't have a fixed ID, then JSF will use an autogenerated ID in j_idXXX format. You should absolutely avoid that by giving them a fixed ID. The OmniFaces NoAutoGeneratedIdViewHandler may be helpful in this during development.

If you know to find the javadoc of the UIComponent in question, then you can also just check in there whether it implements the NamingContainer interface or not. For example, the HtmlForm (the UIComponent behind <h:form> tag) shows it implements NamingContainer, but the HtmlPanelGroup (the UIComponent behind <h:panelGroup> tag) does not show it, so it does not implement NamingContainer. Here is the javadoc of all standard components and here is the javadoc of PrimeFaces.

Solving your problem

So in your case of:

<p:tabView id="tabs"><!-- This is a NamingContainer -->
    <p:tab id="search"><!-- This is NOT a NamingContainer -->
        <h:form id="insTable"><!-- This is a NamingContainer -->
            <p:dialog id="dlg"><!-- This is NOT a NamingContainer -->
                <h:panelGrid id="display">

The generated HTML output of <h:panelGrid id="display"> looks like this:

<table id="tabs:insTable:display">

You need to take exactly that id as client ID and then prefix with : for usage in update:

<p:commandLink update=":tabs:insTable:display">

Referencing outside include/tagfile/composite

If this command link is inside an include/tagfile, and the target is outside it, and thus you don't necessarily know the ID of the naming container parent of the current naming container, then you can dynamically reference it via UIComponent#getNamingContainer() like so:

<p:commandLink update=":#{component.namingContainer.parent.namingContainer.clientId}:display">

Or, if this command link is inside a composite component and the target is outside it:

<p:commandLink update=":#{cc.parent.namingContainer.clientId}:display">

Or, if both the command link and target are inside same composite component:

<p:commandLink update=":#{cc.clientId}:display">

See also Get id of parent naming container in template for in render / update attribute

How does it work under the covers

This all is specified as "search expression" in the UIComponent#findComponent() javadoc:

A search expression consists of either an identifier (which is matched exactly against the id property of a UIComponent, or a series of such identifiers linked by the UINamingContainer#getSeparatorChar character value. The search algorithm should operates as follows, though alternate alogrithms may be used as long as the end result is the same:

• Identify the UIComponent that will be the base for searching, by stopping as soon as one of the following conditions is met:
  • If the search expression begins with the the separator character (called an "absolute" search expression), the base will be the root UIComponent of the component tree. The leading separator character will be stripped off, and the remainder of the search expression will be treated as a "relative" search expression as described below.
  • Otherwise, if this UIComponent is a NamingContainer it will serve as the basis.
  • Otherwise, search up the parents of this component. If a NamingContainer is encountered, it will be the base.
  • Otherwise (if no NamingContainer is encountered) the root UIComponent will be the base.
• The search expression (possibly modified in the previous step) is now a "relative" search expression that will be used to locate the component (if any) that has an id that matches, within the scope of the base component. The match is performed as follows:
  • If the search expression is a simple identifier, this value is compared to the id property, and then recursively through the facets and children of the base UIComponent (except that if a descendant NamingContainer is found, its own facets and children are not searched).
  • If the search expression includes more than one identifier separated by the separator character, the first identifier is used to locate a NamingContainer by the rules in the previous bullet point. Then, the findComponent() method of this NamingContainer will be called, passing the remainder of the search expression.

Note that PrimeFaces also adheres the JSF spec, but RichFaces uses "some additional exceptions".

"reRender" uses UIComponent.findComponent() algorithm (with some additional exceptions) to find the component in the component tree.

Those additional exceptions are nowhere in detail described, but it's known that relative component IDs (i.e. those not starting with :) are not only searched in the context of the closest parent NamingContainer, but also in all other NamingContainer components in the same view (which is a relatively expensive job by the way).

Never use prependId="false"

If this all still doesn't work, then verify if you aren't using <h:form prependId="false">. This will fail during processing the ajax submit and render. See also this related question: UIForm with prependId="false" breaks <f:ajax render>.

Referencing specific iteration round of iterating components

It was for long time not possible to reference a specific iterated item in iterating components like <ui:repeat> and <h:dataTable> like so:

<h:form id="form">
    <ui:repeat id="list" value="#{['one','two','three']}" var="item">
        <h:outputText id="item" value="#{item}" /><br/>
    </ui:repeat>

    <h:commandButton value="Update second item">
        <f:ajax render=":form:list:1:item" />
    </h:commandButton>
</h:form>

However, since Mojarra 2.2.5 the <f:ajax> started to support it (it simply stopped validating it; thus you would never face the in the question mentioned exception anymore; another enhancement fix is planned for that later).

This only doesn't work yet in current MyFaces 2.2.7 and PrimeFaces 5.2 versions. The support might come in the future versions. In the meanwhile, your best bet is to update the iterating component itself, or a parent in case it doesn't render HTML, like <ui:repeat>.

When using PrimeFaces, consider Search Expressions or Selectors

PrimeFaces Search Expressions allows you to reference components via JSF component tree search expressions. JSF has several builtin:

• @this: current component
• @form: parent UIForm
• @all: entire document
• @none: nothing

PrimeFaces has enhanced this with new keywords and composite expression support:

• @parent: parent component
• @namingcontainer: parent UINamingContainer
• @widgetVar(name): component as identified by given widgetVar

You can also mix those keywords in composite expressions such as @form:@parent, @this:@parent:@parent, etc.

PrimeFaces Selectors (PFS) as in @(.someclass) allows you to reference components via jQuery CSS selector syntax. E.g. referencing components having all a common style class in the HTML output. This is particularly helpful in case you need to reference "a lot of" components. This only prerequires that the target components have all a client ID in the HTML output (fixed or autogenerated, doesn't matter). See also How do PrimeFaces Selectors as in update="@(.myClass)" work?

Why not just use simple javascript?

var array=[1,2,3,4];
var lastEl = array[array.length-1];

You can write it as a method too, if you like (assuming prototype has not been included on your page):

Array.prototype.last = function() {return this[this.length-1];}

If you cannot see the "Scripts" tab, make sure you are launching Chrome with the right arguments. I had this problem when I launched Chrome for debugging server-side JavaScript with the argument --remote-shell-port=9222. I have no problem if I launch Chrome with no argument.

I use this in php.

private static function ifTableExists(string $database, string $table): bool
    {
        $query = DB::select("
            SELECT 
                IF( EXISTS 
                    (SELECT * FROM information_schema.COLUMNS
                        WHERE TABLE_SCHEMA = '$database'
                        AND TABLE_NAME = '$table'
                        LIMIT 1),
                1, 0)
                AS if_exists
        ");

        return $query[0]->if_exists == 1;
    }

And here is a quick benchmark for both #sample and #rand:

irb(main):014:0* Benchmark.bm do |x|
irb(main):015:1*   x.report('sample') { 1_000_000.times { (1..100).to_a.sample } }
irb(main):016:1>   x.report('rand') { 1_000_000.times { rand(1..100) } }
irb(main):017:1> end
       user     system      total        real
sample  3.870000   0.020000   3.890000 (  3.888147)
rand  0.150000   0.000000   0.150000 (  0.153557)

So, doing rand(a..b) is the right thing

If you go through the official tutorial of angularjs https://docs.angularjs.org/tutorial/step_07

Note: Starting with AngularJS version 1.2, ngRoute is in its own module and must be loaded by loading the additional angular-route.js file, which we download via Bower above.

Also please note from ngRoute api https://docs.angularjs.org/api/ngRoute

Installation First include angular-route.js in your HTML:

You can download this file from the following places:

Google CDN e.g. //ajax.googleapis.com/ajax/libs/angularjs/X.Y.Z/angular-route.js Bower e.g. bower install [email protected] code.angularjs.org e.g. "//code.angularjs.org/X.Y.Z/angular-route.js" where X.Y.Z is the AngularJS version you are running.

Then load the module in your application by adding it as a dependent module:

angular.module('app', ['ngRoute']); With that you're ready to get started!

RouterModule.forRoot([
      { path: 'welcome', component: WelcomeComponent },
      { path: '', redirectTo: 'welcome', pathMatch: 'full' },
      { path: '**', component: 'pageNotFoundComponent' }
    ])

Case 1 pathMatch:'full': In this case, when app is launched on localhost:4200 (or some server) the default page will be welcome screen, since the url will be https://localhost:4200/

If https://localhost:4200/gibberish this will redirect to pageNotFound screen because of path:'**' wildcard

Case 2 pathMatch:'prefix':

If the routes have { path: '', redirectTo: 'welcome', pathMatch: 'prefix' }, now this will never reach the wildcard route since every url would match path:'' defined.

Right-click on an aspx file and choose 'browse with'. I think there's an option there to set as default.

When using TFS, step 2 is actually to rename the folder in source control and then get the latest before reopening the solution.

Maybe this might help you. I added Shell32.lib to my Linker --> Input --> Additional Dependencies and it stopped this error. I found out about it from this post: https://discourse.libsdl.org/t/windows-build-fails-with-missing-symbol-imp-commandlinetoargvw/27256/3

You will need to change the configure port of either Apache or Nginx. After you do this you will need to restart the reconfigured servers, using the 'service' command you used.

Apache

Edit

sudo subl /etc/apache2/ports.conf 

and change the 80 on the following line to something different :

Listen 80

If you just change the port or add more ports here, you will likely also have to change the VirtualHost statement in

sudo subl /etc/apache2/sites-enabled/000-default.conf

and change the 80 on the following line to something different :

<VirtualHost *:80>

then restart by :

sudo service apache2 restart

Nginx

Edit

/etc/nginx/sites-enabled/default

and change the 80 on the following line :

listen 80;

then restart by :

sudo service nginx restart

I had the similar problem. This is the stack trace:

Traceback (most recent call last):

I tried to (re-)install dateutil.parser through all possible ways. It was unsuccessful.

I solved it with

How do I read a string from input?

You can read a single, whitespace terminated word with std::cin like this:

#include<iostream>
#include<string>
using namespace std;

int main()
{
    cout << "Please enter a word:\n";

    string s;
    cin>>s;

    cout << "You entered " << s << '\n';
}

Note that there is no explicit memory management and no fixed-sized buffer that you could possibly overflow. If you really need a whole line (and not just a single word) you can do this:

#include<iostream>
#include<string>
using namespace std;

int main()
{
    cout << "Please enter a line:\n";

    string s;
    getline(cin,s);

    cout << "You entered " << s << '\n';
}

$cfg['Servers'][$i]['auth_type'] = 'cookie';

should work.

From the manual:

auth_type = 'cookie' prompts for a MySQL username and password in a friendly HTML form. This is also the only way by which one can log in to an arbitrary server (if $cfg['AllowArbitraryServer'] is enabled). Cookie is good for most installations (default in pma 3.1+), it provides security over config and allows multiple users to use the same phpMyAdmin installation. For IIS users, cookie is often easier to configure than http.

Several problems arise in this question.

Problem #1 - css Specificity (how to override important rule).

According to specification - to override this selector your selector should be 'stronger' which mean it should be!important and have at least 1 id, 1 class and something else - according to you creating this selector is impossible(as you can't alter page content). So the only possible option is to put something into element style which (could be done with js). Note: style rule should also have !important to override.

Problem #2 - background is not a single property - it is a set of properties (see specification)

So you really need to know what are exact names of properties you want to change (in your case it would be background-image)

Problem #3 - How to remove rule already applied (to get previous value)?

Unfortunately css have no mechanism to dismiss rule which qualify for an element - only to override with "stronger" rule. So you won't be able to solve this task with just setting value to something like 'inherit' or 'default' cause value you want to see is neither inherit from parent nor default. To solve this problem you have couple of options.

1) You may already know what is the value you want to apply. For example you can find out this value based on selector used. So in this case you may know that for selector ".image-list li" you need background-image: url("http://placekitten.com/150/50"). If so - just you this script:

jQuery(".image-list li").attr('style', 'background-image: url("http://placekitten.com/150/50") !important; ');

2) If you don't know the value then you can try to alter page content in such a way, that rule you want to dismiss is no longer qualify for element, whereas rule you want to be shown - still qualify. In this case you may temporary remove id from container element. Here is the code:

jQuery("#an-element").attr('id', '');
var backgroundImage = jQuery(".image-list li").css('background-image');
jQuery("#an-element").attr('id', 'an-element');
jQuery(".image-list li").attr('style', 'background-image: ' + backgroundImage + ' !important; ');

Here is link to fiddle http://jsfiddle.net/o3jn9mzo/

3) As third solution - you may generate element which will qualify for desired selection to find out property value - something like this:

var backgroundImage = jQuery("<div class='image-list'><li></li></div>").find('li').css('background-image');
jQuery(".image-list li").attr('style', 'background-image: ' + backgroundImage + ' !important; ');

P.S.: Sorry for really late response.

There are a number of libraries available for generating graphs.

• Open Flash Cart - Flash based
• GraPHPite
• JS charts - Javascript based
• Libchart

More are listed above and here.

points or lines comes handy if

• y2 is generated later, or
• the new data does not have the same x but still should go into the same coordinate system.

As your ys share the same x, you can also use matplot:

matplot (x, cbind (y1, y2), pch = 19)

(without the pch matplopt will plot the column numbers of the y matrix instead of dots).

Depending on your .NET version you could also use HttpClientExtensions.PostAsJsonAsync method.

To Remove all rows, except the first one (except header), use the below code:

$("#dataTable tr:gt(1)").remove();

Put this on an event

$(function(){
    $('.package').click(function(){
       var content = $('.container').html();
       $(this).html(content);
    });
});

Please see @jlareau answer here: https://stackoverflow.com/questions/11534710/angularjs-how-to-use-routeparams-in-generating-the-templateurl

You can use a function to generate the template string:

var app = angular.module('app',[]);

app.config(
    function($routeProvider) {
        $routeProvider.
            when('/', {templateUrl:'/home'}).
            when('/users/:user_id', 
                {   
                    controller:UserView, 
                    templateUrl: function(params){ return '/users/view/' + params.user_id;   }
                }
            ).
            otherwise({redirectTo:'/'});
    }
);

You don't need (shouldn't use) a function as far as I can tell. The stored procedure will return tabular data from any SELECT statements you include that return tabular data.

A stored proc does not use RETURN statements.

 CREATE PROCEDURE name
 AS

 SELECT stuff INTO #temptbl1

 .......


 SELECT columns FROM #temptbln

I agree with what @fge said, more over. Lets look at example. Consider you have a method:

class A {
    public void foo(OtherClass other) {
        SomeData data = new SomeData("Some inner data");
        other.doSomething(data);
    }
}

Now if you want to check the inner data you can use the captor:

// Create a mock of the OtherClass
OtherClass other = mock(OtherClass.class);

// Run the foo method with the mock
new A().foo(other);

// Capture the argument of the doSomething function
ArgumentCaptor<SomeData> captor = ArgumentCaptor.forClass(SomeData.class);
verify(other, times(1)).doSomething(captor.capture());

// Assert the argument
SomeData actual = captor.getValue();
assertEquals("Some inner data", actual.innerData);

A more generalised example - if looking for parts of a word OR specific words in a string:

df = pd.DataFrame([('cat andhat', 1000.0), ('hat', 2000000.0), ('the small dog', 1000.0), ('fog', 330000.0),('pet', 330000.0)], columns=['col1', 'col2'])

Specific parts of sentence or word:

searchfor = '.*cat.*hat.*|.*the.*dog.*'

Creat column showing the affected rows (can always filter out as necessary)

df["TrueFalse"]=df['col1'].str.contains(searchfor, regex=True)

    col1             col2           TrueFalse
0   cat andhat       1000.0         True
1   hat              2000000.0      False
2   the small dog    1000.0         True
3   fog              330000.0       False
4   pet 3            30000.0        False

In reply to Is there a specific reason?, here is one interesting application: breaking out of multiple levels of looping.

Here is how it works: the outer loop has a break at the end, so it would only be executed once. However, if the inner loop completes (finds no divisor), then it reaches the else statement and the outer break is never reached. This way, a break in the inner loop will break out of both loops, rather than just one.

for k in [2, 3, 5, 7, 11, 13, 17, 25]:
    for m in range(2, 10):
        if k == m:
            continue
        print 'trying %s %% %s' % (k, m)
        if k % m == 0:
            print 'found a divisor: %d %% %d; breaking out of loop' % (k, m)
            break
    else:
        continue
    print 'breaking another level of loop'
    break
else:
    print 'no divisor could be found!'

For both while and for loops, the else statement is executed at the end, unless break was used.

In most cases there are better ways to do this (wrapping it into a function or raising an exception), but this works!

There is a String.prototype.includes in ES6:

"potato".includes("to");
> true

Note that this does not work in Internet Explorer or some other old browsers with no or incomplete ES6 support. To make it work in old browsers, you may wish to use a transpiler like Babel, a shim library like es6-shim, or this polyfill from MDN:

if (!String.prototype.includes) {
  String.prototype.includes = function(search, start) {
    'use strict';
    if (typeof start !== 'number') {
      start = 0;
    }

    if (start + search.length > this.length) {

Here is what I did for Windows 10! I also did not disturb my previous installation of Python 2.7

Step1: Install Windows x86-64 executable installer from the link: https://www.python.org/downloads/release/python-352/

Step2: Open cmd as Administrator

Step3: Type this command:

pip install https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-0.12.0rc0-cp35-cp35m-win_amd64.whl

You should see that it works and as shown in the picture below, I also tried the sample example.

If the NFS server disappeared and you can't get it back online, one trick that I use is to add an alias to the interface with the IP of the NFS server (in this example, 192.0.2.55).

Linux

The command for that is something roughly like:

ifconfig eth0:fakenfs 192.0.2.55 netmask 255.255.255.255

Where 192.0.2.55 is the IP of the NFS server that went away. You should then be able to ping the address, and you should also be able to unmount the filesystem (use unmount -f). You should then destroy the aliased interface so you no longer route traffic to the old NFS server to yourself with:

ifconfig eth0:fakenfs down

FreeBSD and similar operating systems

The command would be something like:

ifconfig em0 alias 192.0.2.55 netmask 255.255.255.255

And then to remove it:

ifconfig em0 delete 192.0.2.55

man ifconfig(8) for more!

Here's a nice answer from the FAQ on the scipy.org website:

What advantages do NumPy arrays offer over (nested) Python lists?

Python’s lists are efficient general-purpose containers. They support (fairly) efficient insertion, deletion, appending, and concatenation, and Python’s list comprehensions make them easy to construct and manipulate. However, they have certain limitations: they don’t support “vectorized” operations like elementwise addition and multiplication, and the fact that they can contain objects of differing types mean that Python must store type information for every element, and must execute type dispatching code when operating on each element. This also means that very few list operations can be carried out by efficient C loops – each iteration would require type checks and other Python API bookkeeping.

With deployments that have stateful sets (or services, jobs, etc.) you can use this command:

This command terminates anything that runs in the specified <NAMESPACE>

kubectl -n <NAMESPACE> delete replicasets,deployments,jobs,service,pods,statefulsets --all

And forceful

kubectl -n <NAMESPACE> delete replicasets,deployments,jobs,service,pods,statefulsets --all --cascade=true --grace-period=0 --force

Another option is to use VBA in Excel, and write a macro to parse the spreadsheet data and write it into SQL.

One example is here: http://www.ozgrid.com/forum/showthread.php?t=26621&page=1

Sub InsertARecord() 
Dim cnt As ADODB.Connection 
Dim rst As ADODB.Recordset 
Dim stCon As String, stSQL As String 
Set cnt = New ADODB.Connection 
Set rst = New ADODB.Recordset 

stCon = "Provider=MSDASQL.1;Persist Security Info=False;Data Source=JOEY" 
cnt.ConnectionString = stCon 
stSQL = "INSERT INTO MyTable (Price)" 
stSQL = stSQL & "VALUES (500)" 

cnt.Open 
rst.Open stSQL, cnt, adOpenStatic, adLockReadOnly, adCmdText 

If CBool(rst.State And adStateOpen) = True Then rst.Close 
Set rst = Nothing 
If CBool(cnt.State And adStateOpen) = True Then cnt.Close 
Set cnt = Nothing 

End Sub

No.

What are you trying to do?

If you don't want the event to be continuous (if you want the user to have to release the key each time), change onkeydown to onkeyup

window.onkeydown = function (e) {
    var code = e.keyCode ? e.keyCode : e.which;
    if (code === 38) { //up key
        alert('up');
    } else if (code === 40) { //down key
        alert('down');
    }
};

create a key using

keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000

then sign the apk using :

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore my_application.apk alias_name

/^\d{4}$/ This will check if a string consists of only 4 numbers. In this scenario, to input a year 989, you can give 0989 instead.

You can't modify strings; they're immutable. You can do this instead:

txtBox.Text = txtBox.Text.Substring(0, i) + "TEXT" + txtBox.Text.Substring(i);

(Swift 3) Add text box and uipickerview to the storyboard then add delegate and data source to uipickerview and add delegate to textbox. Follow video for assistance https://youtu.be/SfjZwgxlwcc

I gather the documentation wasn't great back in 2012 when this question was asked, but for anyone reading this in 2020+: There's now a whole section in the docs about how to add a source set for integration tests. You really should read it instead of copy/pasting code snippets here and banging your head against the wall trying to figure out why an answer from 2012-2016 doesn't quite work.

The answer is most likely simple but more nuanced than you may think, and the exact code you'll need is likely to be different from the code I'll need. For example, do you want your integration tests to use the same dependencies as your unit tests?

I am on shared hosting, so I can't do a lot of queries otherwise I get a blank page.

That sounds very peculiar. I've got the cheapest PHP hosting package I could find for my last project - and it does not behave like this. I would not pay for a service which did. Indeed, I'm stumped to even know how I could configure a server to replicate this behaviour.

Regardless of why it behaves this way, adding a sleep in the middle of the script cannot resolve the problem.

Since, presumably, you control your product catalog, new products should be relatively infrequent (or are you trying to get stock reports?). If you control when you change the data, why run the scripts automatically? Or do you mean that you already have these URLs and you get the expected files when you run them one at a time?

no need to require the ckeditor.php, because CKEditor will not processed by PHP...

you need just following the _samples directory and see what they do.

just need to include ckeditor.js by html tag, and do some configuration in javascript.

I'm not expert enough in the inner workings of Postgres to know why your query with the double condition in the WHERE clause be not working. But one way to get around this would be to use a UNION of the two queries which you know do work:

SELECT * FROM table_name WHERE boolean_column IS NULL
UNION
SELECT * FROM table_name WHERE boolean_column = FALSE

You could also try using COALESCE:

SELECT * FROM table_name WHERE COALESCE(boolean_column, FALSE) = FALSE

This second query will replace all NULL values with FALSE and then compare against FALSE in the WHERE condition.

This is an old thread but for more recent Jenkins versions (in my case Jenkins 2.135) that require a particular java JDK the following should help:

Note: This is for Centos 7 , other distros may have differing directory locations although I believe they are correct for ubuntu also.

Modify /etc/sysconfig/jenkins and set variable JENKINS_JAVA_CMD="/<your desired jvm>/bin/java" (root access require)

Example:

JENKINS_JAVA_CMD="/usr/lib/jvm/java-1.8.0-openjdk/bin/java"

Restart Jenkins (if jenkins is run as a service sudo service jenkins stop then sudo service jenkins start)

The above fixed my Jenkins install not starting after I upgraded to Java 10 and Jenkins to 2.135

Assuming you are simply trying to get a sklearn.preprocessing.LabelEncoder() object that can be used to represent your columns, all you have to do is:

le.fit(df.columns)

In the above code you will have a unique number corresponding to each column. More precisely, you will have a 1:1 mapping of df.columns to le.transform(df.columns.get_values()). To get a column's encoding, simply pass it to le.transform(...). As an example, the following will get the encoding for each column:

le.transform(df.columns.get_values())

Assuming you want to create a sklearn.preprocessing.LabelEncoder() object for all of your row labels you can do the following:

le.fit([y for x in df.get_values() for y in x])

In this case, you most likely have non-unique row labels (as shown in your question). To see what classes the encoder created you can do le.classes_. You'll note that this should have the same elements as in set(y for x in df.get_values() for y in x). Once again to convert a row label to an encoded label use le.transform(...). As an example, if you want to retrieve the label for the first column in the df.columns array and the first row, you could do this:

le.transform([df.get_value(0, df.columns[0])])

The question you had in your comment is a bit more complicated, but can still be accomplished:

le.fit([str(z) for z in set((x[0], y) for x in df.iteritems() for y in x[1])])

The above code does the following:

1. Make a unique combination of all of the pairs of (column, row)
2. Represent each pair as a string version of the tuple. This is a workaround to overcome the LabelEncoder class not supporting tuples as a class name.
3. Fits the new items to the LabelEncoder.

Now to use this new model it's a bit more complicated. Assuming we want to extract the representation for the same item we looked up in the previous example (the first column in df.columns and the first row), we can do this:

le.transform([str((df.columns[0], df.get_value(0, df.columns[0])))])

Remember that each lookup is now a string representation of a tuple that contains the (column, row).

The problem is probably somewhere else. Try this code for example:

Sub test()

  origNum = "006260006"
  creditOrDebit = "D"

  If (origNum = "006260006" Or origNum = "30062600006") And creditOrDebit = "D" Then
    MsgBox "OK"
  End If

End Sub

And you will see that your Or works as expected. Are you sure that your ElseIf statement is executed (it will not be executed if any of the if/elseif before is true)?

A Quick and dirty way: Just write your query as db.getCollection('collection').find({}).toArray() and right click Copy JSON. Paste the data in the editor of your choice.
