UML from

Product: It defines an interface of the objects the Factory method creates.

ConcreteProduct: Implements Product interface

Creator: Declares the Factory method

ConcreateCreator: Implements the Factory method to return an instance of a ConcreteProduct

Problem statement: Create a Factory of Games by using Factory Methods, which defines the game interface.

Code snippet:

import java.util.HashMap;


/* Product interface as per UML diagram */
interface Game{
    /* createGame is a complex method, which executes a sequence of game steps */
    public void createGame();
}

/* ConcreteProduct implementation as per UML diagram */
class Chess implements Game{
    public Chess(){

    }
    public void createGame(){

        System.out.println("Place 16 pieces for Black opponent");
        System.out.println("Start Chess game");
        System.out.println("---------------------------------------");
    }
}
class Checkers implements Game{
    public Checkers(){

    }
    public void createGame(){
        System.out.println("---------------------------------------");
        System.out.println("Create Checkers game");
        System.out.println("Opponents:2 or 3 or 4 or 6");
        System.out.println("For each opponent, place 10 coins");
        System.out.println("Start Checkers game");
        System.out.println("---------------------------------------");
    }
}
class Ludo implements Game{
    public Ludo(){

    }
    public void createGame(){
        System.out.println("---------------------------------------");
        System.out.println("Create Ludo game");
        System.out.println("Opponents:2 or 3 or 4");
        System.out.println("For each opponent, place 4 coins");
        System.out.println("Create two dices with numbers from 1-6");
        System.out.println("Start Ludo game");
        System.out.println("---------------------------------------");
    }
}

/* Creator interface as per UML diagram */
interface IGameFactory {
    public Game getGame(String gameName);
}

/* ConcreteCreator implementation as per UML diagram */
class GameFactory implements IGameFactory {

     HashMap<String,Game> games = new HashMap<String,Game>();
    /*  
        Since Game Creation is complex process, we don't want to create game using new operator every time.
        Instead we create Game only once and store it in Factory. When client request a specific game, 
        Game object is returned from Factory instead of creating new Game on the fly, which is time consuming
    */

    public GameFactory(){

        games.put(Chess.class.getName(),new Chess());
        games.put(Checkers.class.getName(),new Checkers());
        games.put(Ludo.class.getName(),new Ludo());        
    }
    public Game getGame(String gameName){
        return games.get(gameName);
    }
}

public class NonStaticFactoryDemo{
    public static void main(String args[]){
        if ( args.length < 1){
            System.out.println("Usage: java FactoryDemo gameName");
            return;
        }

        GameFactory factory = new GameFactory();
        Game game = factory.getGame(args[0]);
        if ( game != null ){                    
            game.createGame();
            System.out.println("Game="+game.getClass().getName());
        }else{
            System.out.println(args[0]+  " Game does not exists in factory");
        }           
    }
}

output:

java NonStaticFactoryDemo Chess
---------------------------------------
Create Chess game
Opponents:2
Define 64 blocks
Place 16 pieces for White opponent
Place 16 pieces for Black opponent
Start Chess game
---------------------------------------
Game=Chess

This example shows a Factory class by implementing a FactoryMethod.

1. Game is the interface for all type of games. It defines complex method: createGame()

2. Chess, Ludo, Checkers are different variants of games, which provide implementation to createGame()

3. public Game getGame(String gameName) is FactoryMethod in IGameFactory class

4. GameFactory pre-creates different type of games in constructor. It implements IGameFactory factory method.

5. game Name is passed as command line argument to NotStaticFactoryDemo

6. getGame in GameFactory accepts a game name and returns corresponding Game object.

Factory:

Creates objects without exposing the instantiation logic to the client.

FactoryMethod

Define an interface for creating an object, but let the subclasses decide which class to instantiate. The Factory method lets a class defer instantiation to subclasses

Use case:

When to use: Client doesn't know what concrete classes it will be required to create at runtime, but just wants to get a class that will do the job.

jQuery is required ;-)

The answer above is correct. Please be sure that you have a string data in base64 in the data variable without any prefix or stuff like that just raw data.

Here's what I did on the server side (asp.net mvc core):

string path = Path.Combine(folder, fileName);
Byte[] bytes = System.IO.File.ReadAllBytes(path);
string base64 = Convert.ToBase64String(bytes);

On the client side, I did the following code:

const xhr = new XMLHttpRequest();

xhr.open("GET", url);
xhr.setRequestHeader("Content-Type", "text/plain");

xhr.onload = () => {
    var bin = atob(xhr.response);
    var ab = s2ab(bin); // from example above
    var blob = new Blob([ab], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;' });

    var link = document.createElement('a');
    link.href = window.URL.createObjectURL(blob);
    link.download = 'demo.xlsx';

    document.body.appendChild(link);

    link.click();

    document.body.removeChild(link);
};

xhr.send();

And it works perfectly for me.

In addition to standard net/http package, you can consider using my GoRequest which wraps around net/http and make your life easier without thinking too much about json or struct. But you can also mix and match both of them in one request! (you can see more details about it in gorequest github page)

So, in the end your code will become like follow:

func main() {
    url := "http://restapi3.apiary.io/notes"
    fmt.Println("URL:>", url)
    request := gorequest.New()
    titleList := []string{"title1", "title2", "title3"}
    for _, title := range titleList {
        resp, body, errs := request.Post(url).
            Set("X-Custom-Header", "myvalue").
            Send(`{"title":"` + title + `"}`).
            End()
        if errs != nil {
            fmt.Println(errs)
            os.Exit(1)
        }
        fmt.Println("response Status:", resp.Status)
        fmt.Println("response Headers:", resp.Header)
        fmt.Println("response Body:", body)
    }
}

This depends on how you want to achieve. I made this library because I have the same problem with you and I want code that is shorter, easy to use with json, and more maintainable in my codebase and production system.

 <?php
$array["a"] = "Thusitha";
$array["b"] = "Sumanadasa";
$array["c"] = "Lakmal";
$array["d"] = "Nanayakkara";

$str = serialize($array);
$strenc = urlencode($str);
print $str . "\n";
print $strenc . "\n";
?> 

print $str . "\n"; gives a:4:{s:1:"a";s:8:"Thusitha";s:1:"b";s:10:"Sumanadasa";s:1:"c";s:6:"Lakmal";s:1:"d";s:11:"Nanayakkara";} and

print $strenc . "\n"; gives

a%3A4%3A%7Bs%3A1%3A%22a%22%3Bs%3A8%3A%22Thusitha%22%3Bs%3A1%3A%22b%22%3Bs%3A10%3A%22Sumanadasa%22%3Bs%3A1%3A%22c%22%3Bs%3A6%3A%22Lakmal%22%3Bs%3A1%3A%22d%22%3Bs%3A11%3A%22Nanayakkara%22%3B%7D

So if you want to pass this $array through URL to page_no_2.php,

ex:-

$url ='http://page_no_2.php?data=".$strenc."';

To return back to the original array, it needs to be urldecode(), then unserialize(), like this in page_no_2.php:

    <?php
    $strenc2= $_GET['data'];
    $arr = unserialize(urldecode($strenc2));
    var_dump($arr);
    ?>

gives

 array(4) {
  ["a"]=>
  string(8) "Thusitha"
  ["b"]=>
  string(10) "Sumanadasa"
  ["c"]=>
  string(6) "Lakmal"
  ["d"]=>
  string(11) "Nanayakkara"
}

again :D

If the table already contains data and you want to change one of the columns to identity:

First create a new table that has the same columns and specify the primary key-kolumn:

create table TempTable
(
    Id int not null identity(1, 1) primary key
    --, Other columns...
)

Then copy all rows from the original table to the new table using a standard insert-statement.

Then drop the original table.

And finally rename TempTable to whatever you want using sp_rename:

http://msdn.microsoft.com/en-us/library/ms188351.aspx

You can escape (this is how this principle is called) the double quotes by prefixing them with another double quote. You can put them in a string as follows:

Dim MyVar as string = "some text ""hello"" "

This will give the MyVar variable a value of some text "hello".

Find your stopped container id

docker ps -a

Commit the stopped container:

This command saves modified container state into a new image user/test_image

docker commit $CONTAINER_ID user/test_image

Start/run with a different entry point:

docker run -ti --entrypoint=sh user/test_image

Entrypoint argument description: https://docs.docker.com/engine/reference/run/#/entrypoint-default-command-to-execute-at-runtime

Note:

Steps above just start a stopped container with the same filesystem state. That is great for a quick investigation. But environment variables, network configuration, attached volumes and other staff is not inherited, you should specify all these arguments explicitly.

Steps to start a stopped container have been borrowed from here: (last comment) https://github.com/docker/docker/issues/18078

Not sure why Matthew's solution didn't work for me (could be that I'm using OSX10.8 or perhaps something to do with macports). But I added the following to the end of the file at ~/.profile

export PYTHONPATH=/path/to/dir:$PYTHONPATH

my directory is now on the pythonpath -

and I can import modules from that directory.

write a cloud function to and update the node count.

const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);

    .onWrite(event => {

      console.log('users number : ', event.data.numChildren());


      return event.data.ref.parent.child('count/users').set(event.data.numChildren());
    });

Another issue is that your database may be in a "non-trusted" location. Go to the trust center settings and add your database location to the trusted locations list.

1. Run a small web server on the client machine. Can be a small 100kb thing. A Python / Perl script, etc.
2. Include a small, pre-compiled C executable that can move the mouse.

3. Run it as a CGI-script via a simple http call, AJAX, whatever - with the coordinates you want to move the mouse to, eg:

   http://localhost:9876/cgi/mousemover?x=200&y=450

PS: For any problem, there are hundreds of excuses as to why, and how - it can't, and shouldn't - be done.. But in this infinite universe, it's really just a matter of determination - as to whether YOU will make it happen.

alias_method can be redefined if need be. (it's defined in the Module class.)

alias's behavior changes depending on its scope and can be quite unpredictable at times.

Verdict: Use alias_method - it gives you a ton more flexibility.

Usage:

def foo
  "foo"
end

alias_method :baz, :foo

I already had python3 installed(via miniconda3) and needed to install python2 alongside in that case brew install python won't install python2, so you would need brew install python@2 .

Now alias python2 refers to python2.x from /usr/bin/python

and alias python3 refers to python3.x from /Users/ishandutta2007/miniconda3/bin/python

and alias python refers to python3 by default.

Now to use python as alias for python2, I added the following to .bashrc file

alias python='/usr/bin/python'.

To go back to python3 as default just remove this line when required.

There is a trick, Arithmetic exceptions only happen when you are playing around with integers and only during / or % operation.

If there is any floating point number in an arithmetic operation, internally all integers will get converted into floating point. This may help you to remember things easily.

Diagnose

If you have pip installed (you should have it until you use Python 3.5), list the installed Python packages, like this:

$ pip list | grep -i keras
Keras (1.1.0)

If you don’t see Keras, it means that the previous installation failed or is incomplete (this lib has this dependancies: numpy (1.11.2), PyYAML (3.12), scipy (0.18.1), six (1.10.0), and Theano (0.8.2).)

Consult the pip.log to see what’s wrong.

You can also display your Python path like this:

$ python3 -c 'import sys, pprint; pprint.pprint(sys.path)'
['',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python35.zip',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/plat-darwin',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/lib-dynload',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages']

Make sure the Keras library appears in the /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages path (the path is different on Ubuntu).

If not, try do uninstall it, and retry installation:

$ pip uninstall Keras

Use a virtualenv

It’s a bad idea to use and pollute your system-wide Python. I recommend using a virtualenv (see this guide).

The best usage is to create a virtualenv directory (in your home, for instance), and store your virtualenvs in:

cd virtualenv/
virtualenv -p python3.5 py-keras
source py-keras/bin/activate
pip install -q -U pip setuptools wheel

Then install Keras:

pip install keras

You get:

$ pip list
Keras (1.1.0)
numpy (1.11.2)
pip (8.1.2)
PyYAML (3.12)
scipy (0.18.1)
setuptools (28.3.0)
six (1.10.0)
Theano (0.8.2)
wheel (0.30.0a0)

But, you also need to install extra libraries, like Tensorflow:

$ python -c "import keras"
Using TensorFlow backend.
Traceback (most recent call last):
  ...
ImportError: No module named 'tensorflow'

The installation guide of TesnsorFlow is here: https://www.tensorflow.org/versions/r0.11/get_started/os_setup.html#pip-installation

If you are targetting .Net 4 there are a few options in System.Collections.Concurrent Namespace

You could use ConcurrentBag<T> in this case instead of List<T>

I see no difference between std::stream/FILE/device. Between buffering and non buffering.

Also note:

• SSD drives "tend" to slow down (lower transfer rates) as they fill up.
• SSD drives "tend" to slow down (lower transfer rates) as they get older (because of non working bits).

I am seeing the code run in 63 secondds.
Thus a transfer rate of: 260M/s (my SSD look slightly faster than yours).

64 * 1024 * 1024 * 8 /*sizeof(unsigned long long) */ * 32 /*Chunks*/

= 16G
= 16G/63 = 260M/s

I get a no increase by moving to FILE* from std::fstream.

#include <stdio.h>

using namespace std;

int main()
{
    
    FILE* stream = fopen("binary", "w");

    for(int loop=0;loop < 32;++loop)
    {
         fwrite(a, sizeof(unsigned long long), size, stream);
    }
    fclose(stream);

}

So the C++ stream are working as fast as the underlying library will allow.

But I think it is unfair comparing the OS to an application that is built on-top of the OS. The application can make no assumptions (it does not know the drives are SSD) and thus uses the file mechanisms of the OS for transfer.

While the OS does not need to make any assumptions. It can tell the types of the drives involved and use the optimal technique for transferring the data. In this case a direct memory to memory transfer. Try writing a program that copies 80G from 1 location in memory to another and see how fast that is.

Edit

I changed my code to use the lower level calls:
ie no buffering.

#include <fcntl.h>
#include <unistd.h>


const unsigned long long size = 64ULL*1024ULL*1024ULL;
unsigned long long a[size];
int main()
{
    int data = open("test", O_WRONLY | O_CREAT, 0777);
    for(int loop = 0; loop < 32; ++loop)
    {   
        write(data, a, size * sizeof(unsigned long long));
    }   
    close(data);
}

This made no diffference.

NOTE: My drive is an SSD drive if you have a normal drive you may see a difference between the two techniques above. But as I expected non buffering and buffering (when writting large chunks greater than buffer size) make no difference.

Edit 2:

Have you tried the fastest method of copying files in C++

int main()
{
    std::ifstream  input("input");
    std::ofstream  output("ouptut");

    output << input.rdbuf();
}

You would want to use ->forget()

$collection->forget($key);

Link to the forget method documentation

In MVVM (wich makes a lot of things a lot easier - you should try it) you would have two properties in your ViewModel Text that is bound to your TextBox and you would have an ICommand property Apply (or similar) that is bound to the button:

<Button Command="Apply">Apply</Button>

The ICommand interface has a Method CanExecute that is where you return true if (!string.IsNullOrWhiteSpace(this.Text). The rest is done by WPF for you (enabling/disabling, executing the actual command on click).

The linked article explains it in detail.

When you make it static final it should be initialized in a static initialization block

    private static final List foo;

    static {
        foo = new ArrayList();
    }

    public Test()
    {
//      foo = new ArrayList();
        foo.add("foo"); // Modification-1
    }

As another poster said, it's typically preferable to have interfaces define capabilities not types. I would tend not to "implement" something like a "User," and this is why "IUser" often isn't really necessary in the way described here. I often see classes as nouns and interfaces as adjectives:

class Number implements Comparable{...}  
class MyThread implements Runnable{...}
class SessionData implements Serializable{....}

Sometimes an Adjective doesn't make sense, but I'd still generally be using interfaces to model behavior, actions, capabilities, properties, etc,... not types.

Also, If you were really only going to make one User and call it User then what's the point of also having an IUser interface? And if you are going to have a few different types of users that need to implement a common interface, what does appending an "I" to the interface save you in choosing names of the implementations?

I think a more realistic example would be that some types of users need to be able to login to a particular API. We could define a Login interface, and then have a "User" parent class with SuperUser, DefaultUser, AdminUser, AdministrativeContact, etc suclasses, some of which will or won't implement the Login (Loginable?) interface as necessary.

Because the Method2 is static, all you have to do is call like this:

public class AllMethods
{
    public static void Method2()
    {
        // code here
    }
}

class Caller
{
    public static void Main(string[] args)
    {
        AllMethods.Method2();
    }
}

If they are in different namespaces you will also need to add the namespace of AllMethods to caller.cs in a using statement.

If you wanted to call an instance method (non-static), you'd need an instance of the class to call the method on. For example:

public class MyClass
{
    public void InstanceMethod() 
    { 
        // ...
    }
}

public static void Main(string[] args)
{
    var instance = new MyClass();
    instance.InstanceMethod();
}

Update

As of C# 6, you can now also achieve this with using static directive to call static methods somewhat more gracefully, for example:

// AllMethods.cs
namespace Some.Namespace
{
    public class AllMethods
    {
        public static void Method2()
        {
            // code here
        }
    }
}

// Caller.cs
using static Some.Namespace.AllMethods;

namespace Other.Namespace
{
    class Caller
    {
        public static void Main(string[] args)
        {
            Method2(); // No need to mention AllMethods here
        }
    }
}

I have looked at each of these solutions that also seem to work with one issue. Dark Mode and the background setting

The Background setting of the UITextField must match the background of the parent view or no line appears

So this will work on light mode To get to work in dark mode change the background color to black and it works Exclude back color and the line does not appear

let field = UITextField() 
field.backgroundColor = UIColor.white
field.bottomBorderColor = UIColor.red

This ended up being the best solution for me

extension UITextField {

    func addPadding() {
        let paddingView = UIView(frame: CGRect(x:0, y:0, width: 10, height: self.frame.height))
        self.leftView = paddingView
        self.leftViewMode = .always
      }

      @IBInspectable var placeHolderColor: UIColor? {
          get {
              return self.placeHolderColor
          }
          set {
            self.attributedPlaceholder = NSAttributedString(string:self.placeholder != nil ? self.placeholder! : "", attributes:[NSAttributedString.Key.foregroundColor: newValue!])
          }
      }

      @IBInspectable var bottomBorderColor: UIColor? {
          get {
              return self.bottomBorderColor
          }
          set {
            self.borderStyle = .none
            self.layer.masksToBounds = false
            self.layer.shadowColor = newValue?.cgColor
            self.layer.shadowOffset = CGSize(width: 0.0, height: 1.0)
            self.layer.shadowOpacity = 1.0
            self.layer.shadowRadius = 0.0
          }
      }
    }

You can use the text method and pass a function that returns the modified text, using the native String.prototype.replace method to perform the replacement:

?$(".text_div").text(function () {
    return $(this).text().replace("contains", "hello everyone"); 
});?????

Here's a working example.

And if you also want the deserialised object to have functions, you could use my small tool: https://github.com/khayll/jsmix

//first you'll need to define your model
var GraphNode = function() {};
GraphNode.prototype.getType = function() {
   return this.$type;
}

var Adjacency = function() {};
Adjacency.prototype.getData =n function() {
    return this.data;
}

//then you could say:
var result = JSMix(jsonData)
    .withObject(GraphNode.prototype, "*")
    .withObject(Adjacency.prototype, "*.adjacencies")
    .build();

//and use them
console.log(result[1][0].getData());

The recommended way to style the Toolbar for a Light.DarkActionBar clone would be to use Theme.AppCompat.Light.DarkActionbar as parent/app theme and add the following attributes to the style to hide the default ActionBar:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

Then use the following as your Toolbar:

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.AppBarLayout>

For further modifications, you would create styles extending ThemeOverlay.AppCompat.Dark.ActionBar and ThemeOverlay.AppCompat.Light replacing the ones within AppBarLayout->android:theme and Toolbar->app:popupTheme. Also note that this will pick up your ?attr/colorPrimary if you have set it in your main style so you might get a different background color.

You will find a good example of this is in the current project template with an Empty Activity of Android Studio (1.4+).

declare function dbo.minutes2hours (
    @minutes int
)
RETURNS varchar(10)
as
begin
    return format(dateadd(minute,@minutes,'00:00:00'), N'HH\:mm','FR-fr')
end

I know this is an old question, but rather than adding the snapin which is apparently unsupported, I just looked at the EMS shortcut properties and copied those commands.

The full shortcut target is:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noexit -command ". 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'; Connect-ExchangeServer -auto"

So I put the following at the start of my script and it seemed to function as expected:

. 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'
Connect-ExchangeServer -auto

Notes:

• Has to be run in 64bit PS
• This was tested on a server with just the Management Tools installed. It automatically connected to our existing Exchange infrastructure.
• No extensive testing has been done, so I do not know if this method is viable. I will edit this post if I run into any issues.

You could use zip:

>>> lst=[[1,2,3],[11,12,13],[21,22,23]]
>>> zip(*lst)[0]
(1, 11, 21)

Or, Python 3 where zip does not produce a list:

>>> list(zip(*lst))[0]
(1, 11, 21)

Or,

>>> next(zip(*lst))
(1, 11, 21)

Or, (my favorite) use numpy:

>>> import numpy as np
>>> a=np.array([[1,2,3],[11,12,13],[21,22,23]])
>>> a
array([[ 1,  2,  3],
       [11, 12, 13],
       [21, 22, 23]])
>>> a[:,0]
array([ 1, 11, 21])

Try like

HTML in PHP :

echo "<a href='".$link_address."'>Link</a>";

Or even you can try like

echo "<a href='$link_address'>Link</a>";

Or you can use PHP in HTML like

PHP in HTML :

<a href="<?php echo $link_address;?>"> Link </a>

From application perspective, if one needs only to avoid duplicates then HashSet is what you are looking for since it's Lookup, Insert and Remove complexities are O(1) - constant. What this means it does not matter how many elements HashSet has it will take same amount of time to check if there's such element or not, plus since you are inserting elements at O(1) too it makes it perfect for this sort of thing.

You can try using .net:

$Reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $computer1)
$RegKey= $Reg.OpenSubKey("SOFTWARE\\Veritas\\NetBackup\\CurrentVersion")
$NetbackupVersion1 = $RegKey.GetValue("PackageVersion")

As others have said, std::max_element() and std::min_element() return iterators, which need to be dereferenced to obtain the value.

The advantage of returning an iterator (rather than just the value) is that it allows you to determine the position of the (first) element in the container with the maximum (or minimum) value.

For example (using C++11 for brevity):

#include <vector>
#include <algorithm>
#include <iostream>

int main()
{
    std::vector<double> v {1.0, 2.0, 3.0, 4.0, 5.0, 1.0, 2.0, 3.0, 4.0, 5.0};

    auto biggest = std::max_element(std::begin(v), std::end(v));
    std::cout << "Max element is " << *biggest
        << " at position " << std::distance(std::begin(v), biggest) << std::endl;

    auto smallest = std::min_element(std::begin(v), std::end(v));
    std::cout << "min element is " << *smallest
        << " at position " << std::distance(std::begin(v), smallest) << std::endl;
}

This yields:

Max element is 5 at position 4
min element is 1 at position 0

Note:

Using std::minmax_element() as suggested in the comments above may be faster for large data sets, but may give slightly different results. The values for my example above would be the same, but the position of the "max" element would be 9 since...

If several elements are equivalent to the largest element, the iterator to the last such element is returned.

On express 3 you can use directly res.json({foo:bar})

res.json({ msgId: msg.fileName })

See the documentation

There are quite a few answers; some of them are a bit too much theory-heavy. I'll leave why I needed prune once so maybe the need-first/example kind of explanation is useful to someone :)

Problem

I had a folder with about 20 node directories, each having its node_modules directory as expected.

Once you get into any project, you see each ../node_modules/module. But you know how it is. Almost every module has dependencies, so what you are looking at is more like projectN/node_modules/moduleX/node_modules/moduleZ...

I didn't want to drown with a list with the dependency of the dependency of...

Knowing -d n / -depth n, it wouldn't have helped me, as the main/first node_modules directory I wanted of each project was at a different depth, like this:

Projects/MysuperProjectName/project/node_modules/...
Projects/Whatshisname/version3/project/node_modules/...
Projects/project/node_modules/...
Projects/MysuperProjectName/testProject/november2015Copy/project/node_modules/...
[...]

How can I get the first a list of paths ending at the first node_modules and move to the next project to get the same?

Enter -prune

When you add -prune, you'll still have a standard recursive search. Each "path" is analyzed, and every find gets spit out and find keeps digging down like a good chap. But it's the digging down for more node_modules what I didn't want.

So, the difference is that in any of those different paths, -prune will find to stop digging further down that particular avenue when it has found your item. In my case, the node_modules folder.

Would using tail on N-1 lines and directing that into a file, followed by removing the old file, and renaming the new file to the old name do the job?

If i were doing this programatically, i would read through the file, and remember the file offset, after reading each line, so i could seek back to that position to read the file with one less line in it.

Python is upset because you are attempting to assign a value to something that can't be assigned a value.

((t[1])/length) * t[1] += string

When you use an assignment operator, you assign the value of what is on the right to the variable or element on the left. In your case, there is no variable or element on the left, but instead an interpreted value: you are trying to assign a value to something that isn't a "container".

Based on what you've written, you're just misunderstanding how this operator works. Just switch your operands, like so.

string += str(((t[1])/length) * t[1])

Note that I've wrapped the assigned value in str in order to convert it into a str so that it is compatible with the string variable it is being assigned to. (Numbers and strings can't be added together.)

You already got the right answer, but if you dislike the UIColor interface like me, you can do this:

#import "UIColor+Helper.h"
// ...
myLabel.textColor = [UIColor colorWithRGBA:0xA06105FF];

UIColor+Helper.h:

#import <UIKit/UIKit.h>

@interface UIColor (Helper)
+ (UIColor *)colorWithRGBA:(NSUInteger)color;
@end

UIColor+Helper.m:

#import "UIColor+Helper.h"

@implementation UIColor (Helper)

+ (UIColor *)colorWithRGBA:(NSUInteger)color
{
    return [UIColor colorWithRed:((color >> 24) & 0xFF) / 255.0f
                           green:((color >> 16) & 0xFF) / 255.0f
                            blue:((color >> 8) & 0xFF) / 255.0f
                           alpha:((color) & 0xFF) / 255.0f];
}

@end

Change the klik method as follows:

public void klik(object pea, EventArgs e)
{
    Bitmap c = this.DrawMandel();
    Button btn = pea as Button;
    Graphics gr = btn.CreateGraphics();
    gr.DrawImage(b, 150, 200);
}

I've been struggling with this for awhile too. It actually occurred due to some Microsoft Office updates via Windows Update starting in December. It has caused quite a bit of a headache, not to mention hours of lost productivity due to this issue.

One of the updates breaks the forms, and you need to clear the Office cache as stated by UHsoccer

Additionally, another answer thread here: Suddenly several VBA macro errors, mostly 32809 has a link to the MS blog with details.

Another of the updates causes another error where if you create or modify one of these forms (even as simple as saving the form data) it will update the internals of the spreadsheet, which, when given to another person without the updates, will cause the error above.

The solution (if you are working with others on the same spreadsheet)? Sadly, either have everyone you deal with use the office updates, then have them clear the office cache, or revert back to pre Dec '14 updates via a system restore (or by manually removing them).

I know, not much of a solution, right? I'm not happy either.

Just as a back-story, I updated my machine, keeping up with updates, and one of the companies I dealt with did not. I was pulling out my hair just before Christmas trying to figure out the issue, and without any restore points, I finally relented and reformatted.

Now, a month later, the company's IT department updated their workstations. And, without surprise, they began having issues similar to this as well (not to mention when I received their spreadsheets, I had the same issue).

Now, we are all up on the same updates, and everything is well as can be.

Try this :

$('#form1').submit();

or

document.form1.submit();

Your cells object is not fully qualified. You need to add a DOT before the cells object. For example

With Worksheets("Cable Cards")
    .Range(.Cells(RangeStartRow, RangeStartColumn), _
           .Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues

Similarly, fully qualify all your Cells object.

How reliable is your format? If the seperator is always exactly ': ', the following works. If not, a comparatively simple regex should do the job.

As long as you're working with fairly simple variable types, Python's eval function makes persisting variables to files surprisingly easy.

(The below gives you a dictionary, btw, which you mentioned was one of your prefered solutions).

def read_config(filename):
    f = open(filename)
    config_dict = {}
    for lines in f:
        items = lines.split(': ', 1)
        config_dict[items[0]] = eval(items[1])
    return config_dict

In my case, I used the old namespace library while my project was set up making use of androidx one.

The solution was to replace android.support.design.widget.BottomNavigationView component with the right one to escape from support library: com.google.android.material.bottomnavigation.BottomNavigationView.

Can you change the if condition to this:

if (!is.na(comments[l])) print(comments[l]);

You can only check for NA values with is.na().

You could do something like this:

//outside of main
namespace A
{
    enum A
    {
        a = 0,
        b = 69,
        c = 666
    };
};

//in main:

A::A a = A::c;
std::cout << a << std::endl;

Paul's answer seems to defeat the purpose of bootstrap; that of being responsive to the viewport / screen size.

By nesting rows and columns you can achieve the same result, while retaining responsiveness.

Here is an up-to-date response to this problem;

<div class="container-fluid">_x000D_
  <h1>  Responsive Nested Bootstrap </h1> _x000D_
  <div class="row">_x000D_
    <div class="col-md-5" style="background-color:red;">Span 5</div>_x000D_
    <div class="col-md-3" style="background-color:blue;">Span 3</div>_x000D_
    <div class="col-md-2">_x000D_
      <div class="row">_x000D_

I think [ ]{4} might work in the example where you need to detect 4 spaces. Same with the rest: [ ]{1}, [ ]{2} and [ ]{3}. If you want to detect an empty string in general, ^[ ]*$ will do.

You can do this all from within your service executable in response to events fired from the InstallUtil process. Override the OnAfterInstall event to use a ServiceController class to start the service.

http://msdn.microsoft.com/en-us/library/system.serviceprocess.serviceinstaller.aspx

If you don't want to copy the whole tree (with subdirs etc), use or glob.glob("path/to/dir/*.*") to get a list of all the filenames, loop over the list and use shutil.copy to copy each file.

for filename in glob.glob(os.path.join(source_dir, '*.*')):
    shutil.copy(filename, dest_dir)

Go to the Java Build Path in the project properties. Remove the existing JRE System Library Then Add it again i.e. Add Library-->JRE Lib--select jre--->Finish. Lastly select order and export tab select JRE Lib and move on top. That's it.

Formatting and Styling

Yes, see the following from String Resources: Formatting and Styling

If you need to format your strings using String.format(String, Object...), then you can do so by putting your format arguments in the string resource. For example, with the following resource:

<string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>

In this example, the format string has two arguments: %1$s is a string and %2$d is a decimal number. You can format the string with arguments from your application like this:

Resources res = getResources();
String text = String.format(res.getString(R.string.welcome_messages), username, mailCount);

Basic Usage

Note that getString has an overload that uses the string as a format string:

String text = res.getString(R.string.welcome_messages, username, mailCount);

Plurals

If you need to handle plurals, use this:

<plurals name="welcome_messages">
    <item quantity="one">Hello, %1$s! You have a new message.</item>
    <item quantity="other">Hello, %1$s! You have %2$d new messages.</item>
</plurals>

The first mailCount param is used to decide which format to use (single or plural), the other params are your substitutions:

Resources res = getResources();
String text = res.getQuantityString(R.plurals.welcome_messages, mailCount, username, mailCount);

See String Resources: Plurals for more details.

Add an abstraction layer, for example, a YAML file like in this project https://github.com/larytet/dockerfile-generator which looks like

centos7:
    base: centos:centos7
    packager: rpm
    install:
      - $build_essential_centos 
      - rpm-build
    run:
      - $get_release
    env:
      - $environment_vars

A short Python script/make can generate all Dockerfiles from the configuration file.

I found a list, which might be the full list of supported locales by a given Android version (API level): go to Android-sdk\platforms\android-[XX]\data\res\values\ where XX means the API level, and open locale_config.xml with any text editor. It's human readable and can be easily processed if needed.

Although Pascal's answer was detailed and informative it failed to mention some key information in the assumption that everyone knows how to use phpinfo()

For those that don't:

Navigate to your webservers root folder such as /var/www/

Within this folder create a text file called info.php

Edit the file and type phpinfo()

Navigate to the file such as: http://www.example.com/info.php

Here you will see the php.ini path under Loaded Configuration File:

Make sure you delete info.php when you are done.

A very old (ca 1990) trick to get the total size of the environment variables:

set > test
dir test
del test

Here's what I've done:

.resize {
    width: 400px;
    height: auto;
}

.resize {
    width: 300px;
    height: auto;
}

<img class="resize" src="example.jpg"/>

This will keep the image aspect ratio the same.

In tensorflow you create graphs and pass values to that graph. Graph does all the hardwork and generate the output based on the configuration that you have made in the graph. Now When you pass values to the graph then first you need to create a tensorflow session.

tf.Session()

Once session is initialized then you are supposed to use that session because all the variables and settings are now part of the session. So, there are two ways to pass external values to the graph so that graph accepts them. One is to call the .run() while you are using the session being executed.

Other way which is basically a shortcut to this is to use .eval(). I said shortcut because the full form of .eval() is

tf.get_default_session().run(values)

You can check that yourself. At the place of values.eval() run tf.get_default_session().run(values). You must get the same behavior.

what eval is doing is using the default session and then executing run().

Introduction

The ServletContext#getRealPath() is intented to convert a web content path (the path in the expanded WAR folder structure on the server's disk file system) to an absolute disk file system path.

The "/" represents the web content root. I.e. it represents the web folder as in the below project structure:

YourWebProject
 |-- src
 |    :
 |
 |-- web
 |    |-- META-INF
 |    |    `-- MANIFEST.MF
 |    |-- WEB-INF
 |    |    `-- web.xml
 |    |-- index.jsp
 |    `-- login.jsp
 :    

So, passing the "/" to getRealPath() would return you the absolute disk file system path of the /web folder of the expanded WAR file of the project. Something like /path/to/server/work/folder/some.war/ which you should be able to further use in File or FileInputStream.

Note that most starters don't seem to see/realize that you can actually pass the whole web content path to it and that they often use

String absolutePathToIndexJSP = servletContext.getRealPath("/") + "index.jsp"; // Wrong!

or even

String absolutePathToIndexJSP = servletContext.getRealPath("") + "index.jsp"; // Wronger!

instead of

String absolutePathToIndexJSP = servletContext.getRealPath("/index.jsp"); // Right!

Don't ever write files in there

Also note that even though you can write new files into it using FileOutputStream, all changes (e.g. new files or edited files) will get lost whenever the WAR is redeployed; with the simple reason that all those changes are not contained in the original WAR file. So all starters who are attempting to save uploaded files in there are doing it wrong.

Moreover, getRealPath() will always return null or a completely unexpected path when the server isn't configured to expand the WAR file into the disk file system, but instead into e.g. memory as a virtual file system.

getRealPath() is unportable; you'd better never use it

Use getRealPath() carefully. There are actually no sensible real world use cases for it. Based on my 20 years of Java EE experience, there has always been another way which is much better and more portable than getRealPath().

If all you actually need is to get an InputStream of the web resource, better use ServletContext#getResourceAsStream() instead, this will work regardless of the way how the WAR is expanded. So, if you for example want an InputStream of index.jsp, then do not do:

InputStream input = new FileInputStream(servletContext.getRealPath("/index.jsp")); // Wrong!

But instead do:

InputStream input = servletContext.getResourceAsStream("/index.jsp"); // Right!

Or if you intend to obtain a list of all available web resource paths, use ServletContext#getResourcePaths() instead.

Set<String> resourcePaths = servletContext.getResourcePaths("/");

You can obtain an individual resource as URL via ServletContext#getResource(). This will return null when the resource does not exist.

URL resource = servletContext.getResource(path);

Or if you intend to save an uploaded file, or create a temporary file, then see the below "See also" links.

See also:

• getResourceAsStream() vs FileInputStream
• Recommended way to save uploaded files in a servlet application
• Simple ways to keep data on redeployment of Java EE 7 web application

I had the similar issue. The problem was in the passwords: the Keystore and private key used different passwords. (KeyStore explorer was used)

After creating Keystore with the same password as private key had the issue was resolved.

If you want to select the type of console, you can write this in the file "keybinding.json" (this file can be found in the following path "File-> Preferences-> Keyboard Shortcuts") `

//with this you can select what type of console you want
{
    "key": "ctrl+shift+t",
    "command": "shellLauncher.launch"
},

//and this will help you quickly change console
{ 
    "key": "ctrl+shift+j", 
    "command": "workbench.action.terminal.focusNext" 
},
{
    "key": "ctrl+shift+k", 
    "command": "workbench.action.terminal.focusPrevious" 
}`

For the UPDATE

Use:

UPDATE table1 
   SET col1 = othertable.col2,
       col2 = othertable.col3 
  FROM othertable 
 WHERE othertable.col1 = 123;

For the INSERT

Use:

INSERT INTO table1 (col1, col2) 
SELECT col1, col2 
  FROM othertable

You don't need the VALUES syntax if you are using a SELECT to populate the INSERT values.

"Only conventions? Or is there more behind the underscore prefix?"

Apart from privacy conventions, I also wanted to help bring awareness that the underscore prefix is also used for arguments that are dependent on independent arguments, specifically in URI anchor maps. Dependent keys always point to a map.

Example ( from https://github.com/mmikowski/urianchor ) :

$.uriAnchor.setAnchor({
  page   : 'profile',
  _page  : {
    uname   : 'wendy',
    online  : 'today'
  }
});

The URI anchor on the browser search field is changed to:

\#!page=profile:uname,wendy|online,today

This is a convention used to drive an application state based on hash changes.

You could try this:

$in_str = 'this is a test';
$hex_ary = array();
foreach (str_split($in_str) as $chr) {
    $hex_ary[] = sprintf("%02X", ord($chr));
}
echo implode(' ',$hex_ary);

DavidLn's answer has worked well for me in the past. But it doesn't capture all of setPristine's functionality, which tripped me up this time. Here is a fuller shim:

var form_set_pristine = function(form){
    // 2013-12-20 DF TODO: remove this function on Angular 1.1.x+ upgrade
    // function is included natively

    if(form.$setPristine){
        form.$setPristine();
    } else {
        form.$pristine = true;
        form.$dirty = false;
        angular.forEach(form, function (input, key) {
            if (input.$pristine)
                input.$pristine = true;
            if (input.$dirty) {
                input.$dirty = false;
            }
        });
    }
};

I use the ArrayDebugView add-in for Visual Studio (http://arraydebugview.sourceforge.net/).

It seems to be a long dead project (but one I'm looking at continuing myself) but the add-in still works beautifully for me in VS2010 for both C++ and C#.

It has a few quirks (tab order, modal dialog, no close button) but the ability to plot the contents of an array in a graph more than make up for it.

Edit July 2014: I have finally built a new Visual Studio extension to replace ArrayebugView's functionality. It is available on the VIsual Studio Gallery, search for ArrayPlotter or go to http://visualstudiogallery.msdn.microsoft.com/2fde2c3c-5b83-4d2a-a71e-5fdd83ce6b96?SRC=Home

I don't this the all the above answers are giving the exact solution for comparing two lists of Objects. Most of above approaches can be helpful in following limit of comparisons only - Size comparison - Reference comparison

But if we have same sized lists of objects and different data on the objects level then this comparison approaches won't help.

I think the following approach will work perfectly with overriding equals and hashcode method on the user-defined object.

I used Xstream lib for override equals and hashcode but we can override equals and hashcode by out won logics/comparison too.

Here is the example for your reference

    import com.thoughtworks.xstream.XStream;

    import java.text.ParseException;
    import java.util.ArrayList;
    import java.util.List;

    class TestClass {
      private String name;
      private String id;

      public void setName(String value) {
        this.name = value;
      }

      public String getName() {
        return this.name;
      }

      public String getId() {
        return id;
      }

      public void setId(String id) {
        this.id = id;
      }

      /**
       * @see java.lang.Object#equals(java.lang.Object)
       */
      @Override

The most important thing is that you can ignore the fields by Annotation (@XStreamOmitField) if you don't want to include any fields on the equal check of Objects. There are many Annotations like this to configure so have a look deep about the annotations of this lib.

I am sure this answer will save your time to identify the correct approach for comparing two lists of objects :). Please comment if you see any issues on this.

@Query("SELECT distinct new com.model.referential.Asset(firefCode,firefDescription) FROM AssetClass ")
List<AssetClass> findDistinctAsset();

You can add all pages with this code:

JS code:

 /* Top btn */
    $(window).scroll(function() {
        if ($(this).scrollTop()) {
            $('#toTop').fadeIn();
        } else {
            $('#toTop').fadeOut();
        }
    });
    var top_btn_html="<topbtn id='toTop' onclick='gotoTop()'>&#8593;</topbtn>";
    $('document').ready(function(){
        $("body").append(top_btn_html);
    });
    function gotoTop(){
        $("html, body").animate({scrollTop: 0}, 500);    
    }
    /* Top btn */

CSS CODE

/*Scrool top btn*/
#toTop{
    position: fixed;
    z-index: 10000;
    opacity: 0.5;
    right: 5px;
    bottom: 10px;
    background-color: #ccc;
    border: 1px solid black;
    width: 40px;
    height: 40px;
    border-radius: 20px;
    color: black;
    font-size: 22px;
    font-weight: bolder;
    text-align: center;
    vertical-align: middle;
}

It looks like that this limitation can be avoided if you use the following URL pattern:

https://googledrive.com/host/file-id

For your case the download URL will look like this - https://googledrive.com/host/0ByvXJAlpPqQPYWNqY0V3MGs0Ujg

Please keep in mind that this method works only if file is shared with "Public on the web" option.

.navbar-nav {
   float: left;
   margin: 0;
   margin-left: 40%;
}

.navbar-nav.navbar-right:last-child {
   margin-right: -15px;
   margin-left: 0;
}

Updated Fiddle

Since You Have used the float property we don't have many options except to adjust it manually.

Python is not Java, nor C/C++ -- you need to stop thinking that way to really utilize the power of Python.

Python does not have pass-by-value, nor pass-by-reference, but instead uses pass-by-name (or pass-by-object) -- in other words, nearly everything is bound to a name that you can then use (the two obvious exceptions being tuple- and list-indexing).

When you do spam = "green", you have bound the name spam to the string object "green"; if you then do eggs = spam you have not copied anything, you have not made reference pointers; you have simply bound another name, eggs, to the same object ("green" in this case). If you then bind spam to something else (spam = 3.14159) eggs will still be bound to "green".

When a for-loop executes, it takes the name you give it, and binds it in turn to each object in the iterable while running the loop; when you call a function, it takes the names in the function header and binds them to the arguments passed; reassigning a name is actually rebinding a name (it can take a while to absorb this -- it did for me, anyway).

With for-loops utilizing lists, there are two basic ways to assign back to the list:

for i, item in enumerate(some_list):
    some_list[i] = process(item)

or

new_list = []
for item in some_list:
    new_list.append(process(item))
some_list[:] = new_list

Notice the [:] on that last some_list -- it is causing a mutation of some_list's elements (setting the entire thing to new_list's elements) instead of rebinding the name some_list to new_list. Is this important? It depends! If you have other names besides some_list bound to the same list object, and you want them to see the updates, then you need to use the slicing method; if you don't, or if you do not want them to see the updates, then rebind -- some_list = new_list.

I would rather use Last() from LINQ to do it.

rows = rows.Remove(rows.Last());

or

rows = rows.Remove(rows.LastOrDefault());

Use android:descendantFocusability

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="80dip"
    android:background="@color/light_green"
    android:descendantFocusability="blocksDescendants" >

Add above in root layout

The Java virtual machine is organized into three generations: a young generation, an old generation, and a permanent generation. Most objects are initially allocated in the young generation. The old generation contains objects that have survived some number of young generation collections, as well as some large objects that may be allocated directly in the old generation. The permanent generation holds objects that the JVM finds convenient to have the garbage collector manage, such as objects describing classes and methods, as well as the classes and methods themselves.

If you're interested in disabling views in a specific ViewGroup then you can use the interesting, perhaps slightly obscure duplicateParentState. A view state is a set of boolean attributes such as pressed, enabled, activated, and others. Just use this on each child you want to sync to parent ViewGroup:

android:duplicateParentState="true"

Note that it duplicates the entire state and not just the enabled state. This may be what you want! Of course, this approach is best if you're loading layout XML.

The accepted answer work when you have a single line string(the email) but if you have a

multiline string, the error will remain.

Please look into this matter:

<!-- start: definition-->
@{
    dynamic item = new System.Dynamic.ExpandoObject();
    item.MultiLineString = @"a multi-line
                             string";
    item.SingleLineString = "a single-line string";
}
<!-- end: definition-->
<a href="#" onclick="Getinfo('@item.MultiLineString')">6/16/2016 2:02:29 AM</a>
<script>
    function Getinfo(text) {
        alert(text);
    }
</script>

Change the single-quote(') to backtick(`) in Getinfo as bellow and error will be fixed:

<a href="#" onclick="Getinfo(`@item.MultiLineString`)">6/16/2016 2:02:29 AM</a>

Here is one simple solution. It is capable to display and hide custom UIView inside UITableViewCell. Displaying logic is contained inside class extended from UITableViewCell, BaseTableViewCell.

BaseTableViewCell.h

#import <UIKit/UIKit.h>

@interface BaseTableViewCell : UITableViewCell

@property(nonatomic,strong)UIView* customView;

-(void)showCustomView;

-(void)hideCustomView;

@end

BaseTableViewCell.M

#import "BaseTableViewCell.h"

@interface BaseTableViewCell()
{
    BOOL _isCustomViewVisible;
}

@end

@implementation BaseTableViewCell

- (void)awakeFromNib {
    // Initialization code
}

-(void)prepareForReuse
{
    self.customView = nil;
    _isCustomViewVisible = NO;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}

-(void)showCustomView
{
    if(nil != self.customView)
    {
        if(!_isCustomViewVisible)
        {
            _isCustomViewVisible = YES;

            if(!self.customView.superview)
            {
                CGRect frame = self.customView.frame;
                frame.origin.x = self.contentView.frame.size.width;
                self.customView.frame = frame;
                [self.customView willMoveToSuperview:self.contentView];
                [self.contentView addSubview:self.customView];
                [self.customView didMoveToSuperview];
            }

            __weak BaseTableViewCell* blockSelf = self;
            [UIView animateWithDuration:.5 animations:^(){

                for(UIView* view in blockSelf.contentView.subviews)
                {
                    CGRect frame = view.frame;
                    frame.origin.x = frame.origin.x - blockSelf.customView.frame.size.width;
                    view.frame = frame;
                }
            }];
        }
    }
}

-(void)hideCustomView
{
    if(nil != self.customView)
    {
        if(_isCustomViewVisible)
        {
            __weak BaseTableViewCell* blockSelf = self;
            _isCustomViewVisible = NO;
            [UIView animateWithDuration:.5 animations:^(){
                for(UIView* view in blockSelf.contentView.subviews)
                {
                    CGRect frame = view.frame;
                    frame.origin.x = frame.origin.x + blockSelf.customView.frame.size.width;
                    view.frame = frame;
                }
            }];
        }
    }
}

@end

To get this functionality, simple extend your table view cell from BaseTableViewCell.

Next, Inside UIViewController, which implement UITableViewDelegate, create two gesture recognizers to handle left and right swipes.

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    [self.tableView registerNib:[UINib nibWithNibName:CUSTOM_CELL_NIB_NAME bundle:nil] forCellReuseIdentifier:CUSTOM_CELL_ID];

    UISwipeGestureRecognizer* leftSwipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleLeftSwipe:)];
    leftSwipeRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
    [self.tableView addGestureRecognizer:leftSwipeRecognizer];

    UISwipeGestureRecognizer* rightSwipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleRightSwipe:)];
    rightSwipeRecognizer.direction = UISwipeGestureRecognizerDirectionRight;
    [self.tableView addGestureRecognizer:rightSwipeRecognizer];
}

Than add two swipe handlers

- (void)handleLeftSwipe:(UISwipeGestureRecognizer*)recognizer
{
    CGPoint point = [recognizer locationInView:self.tableView];
    NSIndexPath* index = [self.tableView indexPathForRowAtPoint:point];

    UITableViewCell* cell = [self.tableView cellForRowAtIndexPath:index];

    if([cell respondsToSelector:@selector(showCustomView)])
    {
        [cell performSelector:@selector(showCustomView)];
    }
}

- (void)handleRightSwipe:(UISwipeGestureRecognizer*)recognizer
{
    CGPoint point = [recognizer locationInView:self.tableView];
    NSIndexPath* index = [self.tableView indexPathForRowAtPoint:point];

    UITableViewCell* cell = [self.tableView cellForRowAtIndexPath:index];

    if([cell respondsToSelector:@selector(hideCustomView)])
    {
        [cell performSelector:@selector(hideCustomView)];
    }
}

Now, inside cellForRowAtIndexPath, of UITableViewDelegate, you can create custom UIView and attach it to the dequeued cell.

-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    CustomCellTableViewCell* cell = (CustomCellTableViewCell*)[tableView dequeueReusableCellWithIdentifier:@"CustomCellTableViewCell" forIndexPath:indexPath];

    NSArray* nibViews = [[NSBundle mainBundle] loadNibNamed:@"CellCustomView"
                                                      owner:nil
                                                    options:nil];

    CellCustomView* customView = (CellCustomView*)[ nibViews objectAtIndex: 0];

    cell.customView = customView;

    return cell;
}

Of course, this way of loading of custom UIView is just for this example. Manage it as you want.

Either Cybernate or OMG Ponies solution will work. The fundamental problem is that the DATE_FORMAT() function returns a string, not a date. When you wrote

(Select Date_Format(orders.date_purchased,'%m/%d/%Y')) As Date 

I think you were essentially asking MySQL to try to format the values in date_purchased according to that format string, and instead of calling that column date_purchased, call it "Date". But that column would no longer contain a date, it would contain a string. (Because Date_Format() returns a string, not a date.)

I don't think that's what you wanted to do, but that's what you were doing.

Don't confuse how a value looks with what the value is.

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

As much as I love XAML, for this kinds of tasks I switch to code behind. Attached behaviors are a good pattern for this. Keep in mind, Expression Blend 3 provides a standard way to program and use behaviors. There are a few existing ones on the Expression Community Site.

From best to worse:

Option 1 (C99 and newer)

#include <stdbool.h>

Option 2

typedef enum { false, true } bool;

Option 3

typedef int bool;
enum { false, true };

Option 4

typedef int bool;
#define true 1
#define false 0

#Explanation

• Option 1 will work only if you use C99 (or newer) and it's the "standard way" to do it. Choose this if possible.
• Options 2, 3 and 4 will have in practice the same identical behavior. #2 and #3 don't use #defines though, which in my opinion is better.

If you are undecided, go with #1!

I did as per sid saying my env after updating is

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=<mygmailaddress>
MAIL_PASSWORD=<gmailpassword>
MAIL_ENCRYPTION=tls

this did work without 2 step verification. with 2 step verification enabled it did not work for me.

I came across this question when I was trying similar things.

If you are plotting time series graph and if you have used mtplotlib for drawing graphs then use median method to smooth-en the graph

smotDeriv = timeseries.rolling(window=20, min_periods=5, center=True).median()

where timeseries is your set of data passed you can alter windowsize for more smoothining.

Also, if you use Tampermonkey, you can add a script that will add preview with http://htmlpreview.github.com/ button into actions menu beside 'raw', 'blame' and 'history' buttons.

Script like this one: https://gist.github.com/vanyakosmos/83ba165b288af32cf85e2cac8f02ce6d

In case you actually mean what you seem to ask, I'll provide this alternative answer.

You say you want the dict to return a specified value, you do not say you want to set that value at the same time, like defaultdict does. This will do so:

class DictWithDefault(dict):
    def __init__(self, default, **kwargs):
        self.default = default
        super(DictWithDefault, self).__init__(**kwargs)

    def __getitem__(self, key):
        if key in self:
            return super(DictWithDefault, self).__getitem__(key)
        return self.default

Use like this:

d = DictWIthDefault(99, x=5, y=3)
print d["x"]   # 5
print d[42]    # 99
42 in d        # False
d[42] = 3
42 in d        # True

Alternatively, you can use a standard dict like this:

d = {3: 9, 4: 2}
default = 99
print d.get(3, default)  # 9
print d.get(42, default) # 99

You can mock out aw.Clear, either manually or using a testing framework like pymox. Manually, you'd do it using something like this:

class MyTest(TestCase):
  def testClear():
    old_clear = aw.Clear
    clear_calls = 0
    aw.Clear = lambda: clear_calls += 1
    aps.Request('nv2', aw)
    assert clear_calls == 1
    aw.Clear = old_clear

Using pymox, you'd do it like this:

class MyTest(mox.MoxTestBase):
  def testClear():
    aw = self.m.CreateMock(aps.Request)
    aw.Clear()
    self.mox.ReplayAll()
    aps.Request('nv2', aw)

One of the nice things about the syntax is that you can be sure that a CREATE OR REPLACE will never cause you to lose data (the most you will lose is code, which hopefully you'll have stored in source control somewhere).

The equivalent syntax for tables is ALTER, which means you have to explicitly enumerate the exact changes that are required.

EDIT: By the way, if you need to do a DROP + CREATE in a script, and you don't care for the spurious "object does not exist" errors (when the DROP doesn't find the table), you can do this:

BEGIN
  EXECUTE IMMEDIATE 'DROP TABLE owner.mytable';
EXCEPTION
  WHEN OTHERS THEN
    IF sqlcode != -0942 THEN RAISE; END IF;
END;

Adding subtitle, title and a sound to the notification:

With AppleScript:

display notification "Notification text" with title "Notification Title" subtitle "Notification sub-title" sound name "Submarine"

With terminal/bash and osascript:

osascript -e 'display notification "Notification text" with title "Notification Title" subtitle "Notification sub-title" sound name "Submarine"'

An alert can be displayed instead of a notification

Does not take the sub-heading nor the sound tough.

With AppleScript:

display alert "Alert title" message "Your message text line here."

With terminal/bash and osascript:

osascript -e 'display alert "Alert title" message "Your message text line here."'

Add a line in bash for playing the sound after the alert line:

afplay /System/Library/Sounds/Hero.aiff

Add same line in AppleScript, letting shell script do the work:

do shell script ("afplay /System/Library/Sounds/Hero.aiff")

List of macOS built in sounds to choose from here.

Paraphrased from a handy article on terminal and applescript notifications.

How token-based authentication works

In token-based authentication, the client exchanges hard credentials (such as username and password) for a piece of data called token. For each request, instead of sending the hard credentials, the client will send the token to the server to perform authentication and then authorization.

In a few words, an authentication scheme based on tokens follow these steps:

1. The client sends their credentials (username and password) to the server.
2. The server authenticates the credentials and, if they are valid, generate a token for the user.
3. The server stores the previously generated token in some storage along with the user identifier and an expiration date.
4. The server sends the generated token to the client.
5. The client sends the token to the server in each request.
6. The server, in each request, extracts the token from the incoming request. With the token, the server looks up the user details to perform authentication.
   • If the token is valid, the server accepts the request.
   • If the token is invalid, the server refuses the request.
7. Once the authentication has been performed, the server performs authorization.
8. The server can provide an endpoint to refresh tokens.

^{Note: The step 3 is not required if the server has issued a signed token (such as JWT, which allows you to perform stateless authentication).}

What you can do with JAX-RS 2.0 (Jersey, RESTEasy and Apache CXF)

This solution uses only the JAX-RS 2.0 API, avoiding any vendor specific solution. So, it should work with JAX-RS 2.0 implementations, such as Jersey, RESTEasy and Apache CXF.

It is worthwhile to mention that if you are using token-based authentication, you are not relying on the standard Java EE web application security mechanisms offered by the servlet container and configurable via application's web.xml descriptor. It's a custom authentication.

Authenticating a user with their username and password and issuing a token

Create a JAX-RS resource method which receives and validates the credentials (username and password) and issue a token for the user:

@Path("/authentication")
public class AuthenticationEndpoint {

    @POST
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    public Response authenticateUser(@FormParam("username") String username, 
                                     @FormParam("password") String password) {

        try {

            // Authenticate the user using the credentials provided
            authenticate(username, password);

            // Issue a token for the user
            String token = issueToken(username);

            // Return the token on the response
            return Response.ok(token).build();

        } catch (Exception e) {
            return Response.status(Response.Status.FORBIDDEN).build();
        }      
    }

    private void authenticate(String username, String password) throws Exception {
        // Authenticate against a database, LDAP, file or whatever
        // Throw an Exception if the credentials are invalid
    }

    private String issueToken(String username) {
        // Issue a token (can be a random String persisted to a database or a JWT token)
        // The issued token must be associated to a user
        // Return the issued token
    }
}

If any exceptions are thrown when validating the credentials, a response with the status 403 (Forbidden) will be returned.

If the credentials are successfully validated, a response with the status 200 (OK) will be returned and the issued token will be sent to the client in the response payload. The client must send the token to the server in every request.

When consuming application/x-www-form-urlencoded, the client must to send the credentials in the following format in the request payload:

username=admin&password=123456

Instead of form params, it's possible to wrap the username and the password into a class:

public class Credentials implements Serializable {

    private String username;
    private String password;

    // Getters and setters omitted
}

And then consume it as JSON:

@POST
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Response authenticateUser(Credentials credentials) {

    String username = credentials.getUsername();
    String password = credentials.getPassword();

    // Authenticate the user, issue a token and return a response
}

Using this approach, the client must to send the credentials in the following format in the payload of the request:

{
  "username": "admin",
  "password": "123456"
}

Extracting the token from the request and validating it

The client should send the token in the standard HTTP Authorization header of the request. For example:

Authorization: Bearer <token-goes-here>

The name of the standard HTTP header is unfortunate because it carries authentication information, not authorization. However, it's the standard HTTP header for sending credentials to the server.

JAX-RS provides @NameBinding, a meta-annotation used to create other annotations to bind filters and interceptors to resource classes and methods. Define a @Secured annotation as following:

@NameBinding
@Retention(RUNTIME)
@Target({TYPE, METHOD})
public @interface Secured { }

The above defined name-binding annotation will be used to decorate a filter class, which implements ContainerRequestFilter, allowing you to intercept the request before it be handled by a resource method. The ContainerRequestContext can be used to access the HTTP request headers and then extract the token:

@Secured
@Provider
@Priority(Priorities.AUTHENTICATION)
public class AuthenticationFilter implements ContainerRequestFilter {

    private static final String REALM = "example";
    private static final String AUTHENTICATION_SCHEME = "Bearer";

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        // Get the Authorization header from the request
        String authorizationHeader =
                requestContext.getHeaderString(HttpHeaders.AUTHORIZATION);

        // Validate the Authorization header
        if (!isTokenBasedAuthentication(authorizationHeader)) {
            abortWithUnauthorized(requestContext);
            return;
        }

        // Extract the token from the Authorization header
        String token = authorizationHeader
                            .substring(AUTHENTICATION_SCHEME.length()).trim();

        try {

            // Validate the token
            validateToken(token);

        } catch (Exception e) {
            abortWithUnauthorized(requestContext);
        }
    }

    private boolean isTokenBasedAuthentication(String authorizationHeader) {

        // Check if the Authorization header is valid
        // It must not be null and must be prefixed with "Bearer" plus a whitespace
        // The authentication scheme comparison must be case-insensitive
        return authorizationHeader != null && authorizationHeader.toLowerCase()
                    .startsWith(AUTHENTICATION_SCHEME.toLowerCase() + " ");
    }

    private void abortWithUnauthorized(ContainerRequestContext requestContext) {

        // Abort the filter chain with a 401 status code response
        // The WWW-Authenticate header is sent along with the response
        requestContext.abortWith(
                Response.status(Response.Status.UNAUTHORIZED)
                        .header(HttpHeaders.WWW_AUTHENTICATE, 
                                AUTHENTICATION_SCHEME + " realm=\"" + REALM + "\"")
                        .build());
    }

    private void validateToken(String token) throws Exception {
        // Check if the token was issued by the server and if it's not expired
        // Throw an Exception if the token is invalid
    }
}

If any problems happen during the token validation, a response with the status 401 (Unauthorized) will be returned. Otherwise the request will proceed to a resource method.

Securing your REST endpoints

To bind the authentication filter to resource methods or resource classes, annotate them with the @Secured annotation created above. For the methods and/or classes that are annotated, the filter will be executed. It means that such endpoints will only be reached if the request is performed with a valid token.

If some methods or classes do not need authentication, simply do not annotate them:

@Path("/example")
public class ExampleResource {

    @GET
    @Path("{id}")
    @Produces(MediaType.APPLICATION_JSON)
    public Response myUnsecuredMethod(@PathParam("id") Long id) {
        // This method is not annotated with @Secured
        // The authentication filter won't be executed before invoking this method
        ...
    }

    @DELETE
    @Secured
    @Path("{id}")
    @Produces(MediaType.APPLICATION_JSON)
    public Response mySecuredMethod(@PathParam("id") Long id) {
        // This method is annotated with @Secured
        // The authentication filter will be executed before invoking this method
        // The HTTP request must be performed with a valid token
        ...
    }
}

In the example shown above, the filter will be executed only for the mySecuredMethod(Long) method because it's annotated with @Secured.

Identifying the current user

It's very likely that you will need to know the user who is performing the request agains your REST API. The following approaches can be used to achieve it:

Overriding the security context of the current request

Within your ContainerRequestFilter.filter(ContainerRequestContext) method, a new SecurityContext instance can be set for the current request. Then override the SecurityContext.getUserPrincipal(), returning a Principal instance:

final SecurityContext currentSecurityContext = requestContext.getSecurityContext();
requestContext.setSecurityContext(new SecurityContext() {

        @Override
        public Principal getUserPrincipal() {
            return () -> username;
        }

    @Override
    public boolean isUserInRole(String role) {
        return true;
    }

    @Override
    public boolean isSecure() {
        return currentSecurityContext.isSecure();
    }

    @Override
    public String getAuthenticationScheme() {
        return AUTHENTICATION_SCHEME;
    }
});

Use the token to look up the user identifier (username), which will be the Principal's name.

Inject the SecurityContext in any JAX-RS resource class:

@Context
SecurityContext securityContext;

The same can be done in a JAX-RS resource method:

@GET
@Secured
@Path("{id}")
@Produces(MediaType.APPLICATION_JSON)
public Response myMethod(@PathParam("id") Long id, 
                         @Context SecurityContext securityContext) {
    ...
}

And then get the Principal:

Principal principal = securityContext.getUserPrincipal();
String username = principal.getName();

Using CDI (Context and Dependency Injection)

If, for some reason, you don't want to override the SecurityContext, you can use CDI (Context and Dependency Injection), which provides useful features such as events and producers.

Create a CDI qualifier:

@Qualifier
@Retention(RUNTIME)
@Target({ METHOD, FIELD, PARAMETER })
public @interface AuthenticatedUser { }

In your AuthenticationFilter created above, inject an Event annotated with @AuthenticatedUser:

@Inject
@AuthenticatedUser
Event<String> userAuthenticatedEvent;

If the authentication succeeds, fire the event passing the username as parameter (remember, the token is issued for a user and the token will be used to look up the user identifier):

userAuthenticatedEvent.fire(username);

It's very likely that there's a class that represents a user in your application. Let's call this class User.

Create a CDI bean to handle the authentication event, find a User instance with the correspondent username and assign it to the authenticatedUser producer field:

@RequestScoped
public class AuthenticatedUserProducer {

    @Produces
    @RequestScoped
    @AuthenticatedUser
    private User authenticatedUser;

    public void handleAuthenticationEvent(@Observes @AuthenticatedUser String username) {
        this.authenticatedUser = findUser(username);
    }

    private User findUser(String username) {
        // Hit the the database or a service to find a user by its username and return it
        // Return the User instance
    }
}

The authenticatedUser field produces a User instance that can be injected into container managed beans, such as JAX-RS services, CDI beans, servlets and EJBs. Use the following piece of code to inject a User instance (in fact, it's a CDI proxy):

@Inject
@AuthenticatedUser
User authenticatedUser;

Note that the CDI @Produces annotation is different from the JAX-RS @Produces annotation:

• CDI: javax.enterprise.inject.Produces
• JAX-RS: javax.ws.rs.Produces

Be sure you use the CDI @Produces annotation in your AuthenticatedUserProducer bean.

The key here is the bean annotated with @RequestScoped, allowing you to share data between filters and your beans. If you don't wan't to use events, you can modify the filter to store the authenticated user in a request scoped bean and then read it from your JAX-RS resource classes.

Compared to the approach that overrides the SecurityContext, the CDI approach allows you to get the authenticated user from beans other than JAX-RS resources and providers.

Supporting role-based authorization

Please refer to my other answer for details on how to support role-based authorization.

Issuing tokens

A token can be:

• Opaque: Reveals no details other than the value itself (like a random string)
• Self-contained: Contains details about the token itself (like JWT).

See details below:

Random string as token

A token can be issued by generating a random string and persisting it to a database along with the user identifier and an expiration date. A good example of how to generate a random string in Java can be seen here. You also could use:

Random random = new SecureRandom();
String token = new BigInteger(130, random).toString(32);

JWT (JSON Web Token)

JWT (JSON Web Token) is a standard method for representing claims securely between two parties and is defined by the RFC 7519.

It's a self-contained token and it enables you to store details in claims. These claims are stored in the token payload which is a JSON encoded as Base64. Here are some claims registered in the RFC 7519 and what they mean (read the full RFC for further details):

• iss: Principal that issued the token.
• sub: Principal that is the subject of the JWT.
• exp: Expiration date for the token.
• nbf: Time on which the token will start to be accepted for processing.
• iat: Time on which the token was issued.
• jti: Unique identifier for the token.

Be aware that you must not store sensitive data, such as passwords, in the token.

The payload can be read by the client and the integrity of the token can be easily checked by verifying its signature on the server. The signature is what prevents the token from being tampered with.

You won't need to persist JWT tokens if you don't need to track them. Althought, by persisting the tokens, you will have the possibility of invalidating and revoking the access of them. To keep the track of JWT tokens, instead of persisting the whole token on the server, you could persist the token identifier (jti claim) along with some other details such as the user you issued the token for, the expiration date, etc.

When persisting tokens, always consider removing the old ones in order to prevent your database from growing indefinitely.

Using JWT

There are a few Java libraries to issue and validate JWT tokens such as:

• jjwt
• java-jwt
• jose4j

To find some other great resources to work with JWT, have a look at http://jwt.io.

Handling token revocation with JWT

If you want to revoke tokens, you must keep the track of them. You don't need to store the whole token on server side, store only the token identifier (that must be unique) and some metadata if you need. For the token identifier you could use UUID.

The jti claim should be used to store the token identifier on the token. When validating the token, ensure that it has not been revoked by checking the value of the jti claim against the token identifiers you have on server side.

For security purposes, revoke all the tokens for a user when they change their password.

Additional information

• It doesn't matter which type of authentication you decide to use. Always do it on the top of a HTTPS connection to prevent the man-in-the-middle attack.
• Take a look at this question from Information Security for more information about tokens.
• In this article you will find some useful information about token-based authentication.

isfar<-load("C:/Users/isfar.RData") 
if(is.data.frame(isfar)){
   names(isfar)
}

If isfar is a dataframe, this will print out the names of its columns.

As stated by Taylor L, you can't just "stop" a thread (by calling a simple method) due to the fact that it could leave your system in an unstable state as the external calling thread may not know what is going on inside your thread.

With this said, the best way to "stop" a thread is to have the thread keep an eye on itself and to have it know and understand when it should stop.

Unfortunately, Javascript's cookie syntax is nowhere near as nice as that. In fact, in my opinion, it's one of the worst designed parts.

When you try to read document.cookie, you get a string containing all the cookies set. You have to parse the string, separating by the semicolon ; character. Rather than writing this yourself, there are plenty of versions available on the web. My favourite is the one at quirksmode.org. This gives you createCookie, readCookie and deleteCookie functions.

Here is another solution:

for(String serverId : serverIds) {
   sb.append(",");
   sb.append(serverId); 
}

String resultingString = "";
if ( sb.length() > 1 ) {
    resultingString = sb.substring(1);
}

This is speculation, but based on Google's reference to the "risk analysis engine" they use (http://googleonlinesecurity.blogspot.com/2014/12/are-you-robot-introducing-no-captcha.html)

I would assume it looks at how you behaved prior to clicking, how your cursor moved on its way to the check (organic path/acceleration), which part of the checkbox was clicked (random places, or dead on center every time), browser fingerprint, Google cookies & contents, click location history tied to your fingerprint or account if it detects one etc.

It's fairly difficult to fake "organic" behavior in such a way that it would fool a continuously learning pattern detection engine. In the cases where it's not sure, it still prompts you to match an actual CAPTCHA string.

we can use createNativeQuery("Here Nagitive SQL Query ");

for Example :

Query q = em.createNativeQuery("SELECT a.firstname, a.lastname FROM Author a");
List<Object[]> authors = q.getResultList();

I working well with it

<script>
    $(function () {

        $("#catalog tbody tr").draggable({
            appendTo:"body",
            helper:"clone"
        });
        $("#cart tbody").droppable({
            activeClass:"ui-state-default",
            hoverClass:"ui-state-hover",
            accept:":not(.ui-sortable-helper)",
            drop:function (event, ui) {
                $('.placeholder').remove();
                row = ui.draggable;
                $(this).append(row);
            }
        });
    });
</script>

It's simple, use $.getJSON() function and in your URL just include

callback=?

as a parameter. That will convert the call to JSONP which is necessary to make cross-domain calls. More info: http://api.jquery.com/jQuery.getJSON/

How about the List.FindIndex Method:

int index = myList.FindIndex(a => a.Prop == oProp);

This method performs a linear search; therefore, this method is an O(n) operation, where n is Count.

If the item is not found, it will return -1

You can use the report process status ps command:

ps ax | grep '[m]ysqld'

Use this for every external link

$('a[href^="http://"], a[href^="https://"]').attr('target', '_blank');

You can think of a MySQL "database" as a schema/user in Oracle. If you have the privileges, you can query the DBA_USERS view to see the list of schemas:

SELECT * FROM DBA_USERS;

First, the enum methods shouldn't be in all caps. They are methods just like other methods, with the same naming convention.

Second, what you are doing is not the best possible way to set up your enum. Instead of using an array of values for the values, you should use separate variables for each value. You can then implement the constructor like you would any other class.

Here's how you should do it with all the suggestions above:

public enum States {
    ...
    MASSACHUSETTS("Massachusetts",  "MA",   true),
    MICHIGAN     ("Michigan",       "MI",   false),
    ...; // all 50 of those

    private final String full;
    private final String abbr;
    private final boolean originalColony;

    private States(String full, String abbr, boolean originalColony) {
        this.full = full;
        this.abbr = abbr;
        this.originalColony = originalColony;
    }

    public String getFullName() {
        return full;
    }

    public String getAbbreviatedName() {
        return abbr;
    }

    public boolean isOriginalColony(){
        return originalColony;
    }
}

Use the formatting options available to you, use the Decimal format string. It is far more flexible and requires little to no maintenance compared to direct string manipulation.

To get the string representation using at least 4 digits:

int length = 4;
int number = 50;
string asString = number.ToString("D" + length); //"0050"

See the MSDN reference table for maximum numbers/sizes.

Bytes per varchar(max), varbinary(max), xml, text, or image column: 2^31-1

There's a two-byte overhead for the column, so the actual data is 2^31-3 max bytes in length. Assuming you're using a single-byte character encoding, that's 2^31-3 characters total. (If you're using a character encoding that uses more than one byte per character, divide by the total number of bytes per character. If you're using a variable-length character encoding, all bets are off.)

Click Right Click On Your Database The Press tasks>Back Up and take a back up from your database before restore your database i'm using this way to solve this Problem

I've compared performance (space and time) for a number of ways to store numpy arrays. Few of them support multiple arrays per file, but perhaps it's useful anyway.

Npy and binary files are both really fast and small for dense data. If the data is sparse or very structured, you might want to use npz with compression, which'll save a lot of space but cost some load time.

If portability is an issue, binary is better than npy. If human readability is important, then you'll have to sacrifice a lot of performance, but it can be achieved fairly well using csv (which is also very portable of course).

More details and the code are available at the github repo.

I also ran into this situation and figured out how to do it using FrameLayout. The following output is produced by the code given below.

              <FrameLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content" >

                    <ImageView
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:src="@drawable/contactbook_icon"
                        android:layout_gravity="center" />

                    <TextView
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:text="140"
                        android:textSize="12dp"
                        android:textColor="#FFFFFF"
                        android:layout_gravity="bottom|right"
                        android:layout_margin="15dp" />
                </FrameLayout>

Change the margin value to adjust the text position over the image. Removing margin might make the text to go out of the view sometimes.

If you already have the xml, and comes more than one attribute, you can handle it as follows:

String output = "<ciudads><ciudad><idCiudad>1</idCiudad>
<nomCiudad>BOGOTA</nomCiudad></ciudad><ciudad><idCiudad>6</idCiudad>
<nomCiudad>Pereira</nomCiudad></ciudads>";
DocumentBuilder db = DocumentBuilderFactory.newInstance()
    .newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(output));

Document doc = db.parse(is);
NodeList nodes = ((org.w3c.dom.Document) doc)
    .getElementsByTagName("ciudad");

for (int i = 0; i < nodes.getLength(); i++) {           
    Ciudad ciudad = new Ciudad();
    Element element = (Element) nodes.item(i);

    NodeList name = element.getElementsByTagName("idCiudad");
    Element element2 = (Element) name.item(0);
    ciudad.setIdCiudad(Integer
        .valueOf(getCharacterDataFromElement(element2)));

    NodeList title = element.getElementsByTagName("nomCiudad");
    element2 = (Element) title.item(0);
    ciudad.setNombre(getCharacterDataFromElement(element2));

    ciudades.getPartnerAccount().add(ciudad);
}
}

for (Ciudad ciudad1 : ciudades.getPartnerAccount()) {
System.out.println(ciudad1.getIdCiudad());
System.out.println(ciudad1.getNombre());
}

the method getCharacterDataFromElement is

public static String getCharacterDataFromElement(Element e) {
Node child = e.getFirstChild();
if (child instanceof CharacterData) {
CharacterData cd = (CharacterData) child;

return cd.getData();
}
return "";
}

The first bin in the FFT is DC (0 Hz), the second bin is Fs / N, where Fs is the sample rate and N is the size of the FFT. The next bin is 2 * Fs / N. To express this in general terms, the nth bin is n * Fs / N.

So if your sample rate, Fs is say 44.1 kHz and your FFT size, N is 1024, then the FFT output bins are at:

  0:   0 * 44100 / 1024 =     0.0 Hz
  1:   1 * 44100 / 1024 =    43.1 Hz
  2:   2 * 44100 / 1024 =    86.1 Hz
  3:   3 * 44100 / 1024 =   129.2 Hz
  4: ...
  5: ...
     ...
511: 511 * 44100 / 1024 = 22006.9 Hz

Note that for a real input signal (imaginary parts all zero) the second half of the FFT (bins from N / 2 + 1 to N - 1) contain no useful additional information (they have complex conjugate symmetry with the first N / 2 - 1 bins). The last useful bin (for practical aplications) is at N / 2 - 1, which corresponds to 22006.9 Hz in the above example. The bin at N / 2 represents energy at the Nyquist frequency, i.e. Fs / 2 ( = 22050 Hz in this example), but this is in general not of any practical use, since anti-aliasing filters will typically attenuate any signals at and above Fs / 2.

def valid = pointAddress.findAll { a ->

Should do it

The first value is the precision and the second is the scale, so 18,0 is essentially 18 digits with 0 digits after the decimal place. If you had 18,2 for example, you would have 18 digits, two of which would come after the decimal...

example of 18,2: 1234567890123456.12

There is no functional difference between numeric and decimal, other that the name and I think I recall that numeric came first, as in an earlier version.

And to answer, "can I add (-10) in that column?" - Yes, you can.

via command line we in centOs we can do this

This will open a second cmd.exe window. If you want it to go away, replace the /K with /C.

Obviously, replace new_file_loc with whatever your new file location will be.

    call :open "%%i"
    exit /B 0
)
:open
    start "window title" "cmd /K copy %~1 new_file_loc"
exit /B 0

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result, score and grade columns so you don't have multiple columns but you will have multiple rows.

Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:

select ratio, col, value
from GRAND_TOTALS
cross apply
(
  select 'result', cast(result as varchar(10)) union all
  select 'score', cast(score as varchar(10)) union all
  select 'grade', grade
) c(col, value)

See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:

select ratio = col,
  [current ratio], [gearing ratio], [performance ratio], total
from
(
  select ratio, col, value
  from GRAND_TOTALS
  cross apply
  (
    select 'result', cast(result as varchar(10)) union all
    select 'score', cast(score as varchar(10)) union all
    select 'grade', grade
  ) c(col, value)
) d
pivot
(
  max(value)
  for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;

See SQL Fiddle with Demo. This will give you the result:

|  RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO |     TOTAL |
|--------|---------------|---------------|-------------------|-----------|
|  grade |          Good |          Good |      Satisfactory |      Good |
| result |       1.29400 |       0.33840 |           0.04270 |    (null) |
|  score |      60.00000 |      70.00000 |          50.00000 | 180.00000 |

Yes, there is a way. Two in fact. In October 2013 jshint added a way to ignore blocks of code like this:

// Code here will be linted with JSHint.
/* jshint ignore:start */
// Code here will be ignored by JSHint.
/* jshint ignore:end */
// Code here will be linted with JSHint.

You can also ignore a single line with a trailing comment like this:

ignoreThis(); // jshint ignore:line

You can use this code to Download file from a WebSite to Desktop:

using System.Net;

WebClient client = new WebClient ();
client.DownloadFileAsync(new Uri("http://www.Address.com/File.zip"), Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + "File.zip");

You can find the library version accessing the file package.json. Under dependencies, check the property ionic-angular. You can also check the Ionic CLI version typing ionic info in the terminal from your project's folder.

As long as both are referenced by the web page, yes.

You simply call the functions as if they are in the same JS file.

This is taken from Romain Guy's presentation at Devoxx, pdf found here.

Paint mShadow = new Paint(); 
// radius=10, y-offset=2, color=black 
mShadow.setShadowLayer(10.0f, 0.0f, 2.0f, 0xFF000000); 
// in onDraw(Canvas) 
canvas.drawBitmap(bitmap, 0.0f, 0.0f, mShadow);

Hope this helps.

NOTES

1. Don't forget for Honeycomb and above you need to invoke setLayerType(LAYER_TYPE_SOFTWARE, mShadow), otherwise you will not see your shadow! (@Dmitriy_Boichenko)
2. SetShadowLayer does not work with hardware acceleration unfortunately so it greatly reduces performances (@Matt Wear) [1] [2]

You have enabled CORS and enabled Access-Control-Allow-Origin : * in the server.If still you get GET method working and POST method is not working then it might be because of the problem of Content-Type and data problem.

First AngularJS transmits data using Content-Type: application/json which is not serialized natively by some of the web servers (notably PHP). For them we have to transmit the data as Content-Type: x-www-form-urlencoded

Example :-

        $scope.formLoginPost = function () {
            $http({
                url: url,
                method: "POST",
                data: $.param({ 'username': $scope.username, 'Password': $scope.Password }),
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
            }).then(function (response) {
                // success
                console.log('success');
                console.log("then : " + JSON.stringify(response));
            }, function (response) { // optional
                // failed
                console.log('failed');
                console.log(JSON.stringify(response));
            });
        };

Note : I am using $.params to serialize the data to use Content-Type: x-www-form-urlencoded. Alternatively you can use the following javascript function

function params(obj){
    var str = "";
    for (var key in obj) {
        if (str != "") {
            str += "&";
        }
        str += key + "=" + encodeURIComponent(obj[key]);
    }
    return str;
}

and use params({ 'username': $scope.username, 'Password': $scope.Password }) to serialize it as the Content-Type: x-www-form-urlencoded requests only gets the POST data in username=john&Password=12345 form.

The OP's code snippet clearly uses the correct comment markup but CSS can break in a progressive way — so, if there's a syntax error, everything after that is likely to fail. A couple times I've relied on trustworthy sources that supplied incorrect comment markup that broke my style sheet. Since the OP provided just a small section of their code, I'd suggest the following:

Make sure all of your CSS comments use this markup /* ... */ -- which is the correct comment markup for css according to MDN

Validate your css with a linter or a secure online validator. Here's one by W3

More info: I went to check the latest recommended media query breakpoints from bootstrap 4 and ended up copying the boiler plate straight from their docs. Almost every code block was labeled with javascript-style comments //, which broke my code — and gave me only cryptic compile errors with which to troubleshoot, which went over my head at the time and caused me sadness.

IntelliJ text editor allowed me to comment out specific lines of css in a LESS file using the ctrl+/ hotkey which was great except it inserts // by default on unrecognized file types. It isn't freeware and less is fairly mainstream so I trusted it and went with it. That broke my code. There's a preference menu for teaching it the correct comment markup for each filetype.

You can use Internet Explorer to browse folders and files together in tree. It is a file explorer in Favorites Window. You just need replace "favorites folder" to folder which you want see as a root folder

adb shell ip addr > ippdetails.txt This will get all list of ip's assigned to devices.

Insert Selected column with condition

INSERT INTO where_to_insert (col_1,col_2) SELECT col1, col2 FROM from_table WHERE condition;

Copy all data from one table to another with the same column name.

INSERT INTO where_to_insert 
SELECT * FROM from_table WHERE condition;

Before new gallery access in KitKat I got my real path in sdcard with this method

That was never reliable. There is no requirement that the Uri that you are returned from an ACTION_GET_CONTENT or ACTION_PICK request has to be indexed by the MediaStore, or even has to represent a file on the file system. The Uri could, for example, represent a stream, where an encrypted file is decrypted for you on the fly.

How could I manage to obtain the real path in sdcard?

There is no requirement that there is a file corresponding to the Uri.

Yes, I really need a path

Then copy the file from the stream to your own temporary file, and use it. Better yet, just use the stream directly, and avoid the temporary file.

I have changed my Intent.ACTION_GET_CONTENT for Intent.ACTION_PICK

That will not help your situation. There is no requirement that an ACTION_PICK response be for a Uri that has a file on the filesystem that you can somehow magically derive.

Can be done by SerializationUtils, by serialize & deserialize method by ApacheUtils to convert object to byte[] and vice-versa , as stated in @uris answer.

To convert an object to byte[] by serializing:

byte[] data = SerializationUtils.serialize(object);

To convert byte[] to object by deserializing::

Object object = (Object) SerializationUtils.deserialize(byte[] data)

Hope this helps.

For Linux Mint, this problem is actually referenced in the Docker website:

Note: The lsb_release -cs sub-command below returns the name of your Ubuntu distribution, such as xenial. Sometimes, in a distribution like Linux Mint, you might have to change $(lsb_release -cs) to your parent Ubuntu distribution. For example, if you are using Linux Mint Rafaela, you could use trusty.

amd64:

$ sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"

The lsb_release -cs command gives a repository for which Docker has no prepared package - you must change it to xenial.

The correct command for Linux Mint 18 which is based on Ubuntu 16.04 Xenial is

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   xenial \
   stable"

It would be best to just have the http content on https

Use Manatee.Json https://github.com/gregsdennis/Manatee.Json/wiki/Usage

And you can convert the entire object to a string, filename.json is expected to be located in documents folder.

        var text = File.ReadAllText("filename.json");
        var json = JsonValue.Parse(text);

        while (JsonValue.Null != null)
        {
            Console.WriteLine(json.ToString());

        }
        Console.ReadLine();

Run this command to change .cert file to .p12:

openssl pkcs12 -export -out server.p12 -inkey server.key -in server.crt 

Where server.key is the server key and server.cert is a CA issue cert or a self sign cert file.

This happened to me on windows. Any of these commands will work

On Windows CMD (not switching to bash)

docker exec -it <container-id> /bin/sh

On Windows CMD (after switching to bash)

docker exec -it <container-id> //bin//sh

or

winpty docker exec -it <container-id> //bin//sh

On Git Bash

winpty docker exec -it <container-id> //bin//sh

NB: You might need to run use /bin/bash or /bin/sh, depending on the shell in your container.

The reason is documented in the ReleaseNotes file of Git and it is well explained here - Bash in Git for Windows: Weirdness...

"The cause has to do with trying to ensure that posix paths end up being passed to the git utilities properly. For this reason, Git for Windows includes a modified MSYS layer that affects command arguments."

I've used Beej's Guide to Network Programming in the past. It's in C, not C++, but the examples are good. Go directly to section 6 for the simple client and server example programs.

i had the same issue, but I just typed export on top and erased the default one on the bottom. Scroll down and check the comments.

import React, { Component } from "react";

export class Counter extends Component { // type this  
export default Counter; // this is eliminated  

This will print everything after each match, on that same line only:

perl -lne 'print $1 if /^potato:\s*(.*)/' file.txt

This will do the same, except it will also print all subsequent lines:

perl -lne 'if ($found){print} elsif (/^potato:\s*(.*)/){print $1; $found++}' file.txt

These command-line options are used:

• -n loop around each line of the input file
• -l removes newlines before processing, and adds them back in afterwards
• -e execute the perl code

This is even simpler, and perhaps hacky - as I can see a lot of GDI muscle on this thread, and is obviously only a good fit for certain scenarios. YMMV

In my scenario, I use what I'll refer to as a "Parent" UserControl - and during the Load event, I simply remove the control-to-be-manipulated from the Parent's .Controls collection, and the Parent's OnPaint takes care of completely painting the child control in whatever special way.. fully taking the child's paint capabilities offline.

Now, I hand off my child paint routine to an extension method based off this concept from Mike Gold for printing windows forms.

Here I'm needing a sub-set of labels to render perpendicular to the layout:

Then, I exempt the child control from being painted, with this code in the ParentUserControl.Load event handler:

Private Sub ParentUserControl_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    SetStyle(ControlStyles.UserPaint, True)
    SetStyle(ControlStyles.AllPaintingInWmPaint, True)

    'exempt this control from standard painting: 
    Me.Controls.Remove(Me.HostedControlToBeRotated) 
End Sub

Then, in the same ParentUserControl, we paint the control-to-be-manipulated from the ground up:

Protected Overrides Sub OnPaint(e As PaintEventArgs)
    'here, we will custom paint the HostedControlToBeRotated instance...

    'twist rendering mode 90 counter clockwise, and shift rendering over to right-most end 
    e.Graphics.SmoothingMode = Drawing2D.SmoothingMode.AntiAlias
    e.Graphics.TranslateTransform(Me.Width - Me.HostedControlToBeRotated.Height, Me.Height)
    e.Graphics.RotateTransform(-90)
    MyCompany.Forms.CustomGDI.DrawControlAndChildren(Me.HostedControlToBeRotated, e.Graphics)

    e.Graphics.ResetTransform()
    e.Graphics.Dispose()

    GC.Collect()
End Sub

Once you host the ParentUserControl somewhere, e.g. a Windows Form - I'm finding that my Visual Studio 2015 renders the form correctly at Design Time as well as runtime:

Now, since my particular manipulation rotates the child control 90 degrees, I'm sure all the hot spots and interactivity has been destroyed in that region - but, the problem I was solving was all for a package label that needed to preview and print, which worked out fine for me.

If there are ways to reintroduce the hot spots and control-ness to my purposely orphaned control - I'd love to learn about that someday (not for this scenario, of course, but.. just to learn). Of course, WPF supports such craziness OOTB.. but.. hey.. WinForms is so much fun still, amiright?

Try this:

WebRequest request = WebRequest.CreateDefault(RequestUrl);
request.Method = "GET";

WebResponse response;
try { response = request.GetResponse(); }
catch (WebException exc) { response = exc.Response; }

if (response == null)
    throw new HttpException((int)HttpStatusCode.NotFound, "The requested url could not be found.");

using(StreamReader reader = new StreamReader(response.GetResponseStream())) {
    string requestedText = reader.ReadToEnd();

    // do what you want with requestedText
}

Sorry about the C#, I know you asked for VB, but I didn't have time to convert.

Insted of using System.Net.WebClient I would recommend to have a look on System.Net.Http.HttpClient which was introduced with net 4.5 and makes your life much easier.

Also microsoft recommends to use the HttpClient on this article

http://msdn.microsoft.com/en-us/library/system.net.webclient(VS.90).aspx

An example could look like this:

var client = new HttpClient();
var content = new MultipartFormDataContent
{
     { new StringContent("myUserId"), "userid"},
     { new StringContent("myFileName"), "filename"},
     { new StringContent("myPassword"), "password"},
     { new StringContent("myType"), "type"}
};

var responseMessage = await client.PostAsync("some url", content);        
var stream = await responseMessage.Content.ReadAsStreamAsync();

The problem obviously was (as you figured it out) that port 36250 wasn't open on the server side at the time you tried to connect (hence connection refused). I can see the server was supposed to open this socket after receiving SEND command on another connection, but it apparently was "not opening [it] up in sync with the client side".

Well, the main reason would be there was no synchronisation whatsoever. Calling:

cs.send("SEND " + FILE)
cs.close()

would just place the data into a OS buffer; close would probably flush the data and push into the network, but it would almost certainly return before the data would reach the server. Adding sleep after close might mitigate the problem, but this is not synchronisation.

The correct solution would be to make sure the server has opened the connection. This would require server sending you some message back (for example OK, or better PORT 36250 to indicate where to connect). This would make sure the server is already listening.

The other thing is you must check the return values of send to make sure how many bytes was taken from your buffer. Or use sendall.

(Sorry for disturbing with this late answer, but I found this to be a high traffic question and I really didn't like the sleep idea in the comments section.)

That approach will be good if the date-time in question is in UTC, or represents local time in an area that has never observed daylight saving time. The DateTime difference routines do not take into account Daylight Saving Time, and consequently will regard midnight June 1 as being a multiple of 24 hours after midnight January 1. I'm unaware of anything in Windows that reports historical daylight-saving rules for the current locale, so I don't think there's any good way to correctly handle any time prior to the most recent daylight-saving rule change.

settings.py

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME': 'django',
    'USER': 'root',
    'PASSWORD': '*****',
    'HOST': '***.***.***.***',
    'PORT': '3306',
    'OPTIONS': {
        'autocommit': True,
    },
}

}

then:

python manage.py migrate

if success will generate theses tables:

auth_group
auth_group_permissions
auth_permission
auth_user
auth_user_groups
auth_user_user_permissions
django_admin_log
django_content_type
django_migrations
django_session

and u will can use mysql.

this is a showcase example ,test on Django version 1.11.5: Django-pool-showcase

skip = OFFSET
$products = $art->products->skip(0)->take(10)->get(); //get first 10 rows
$products = $art->products->skip(10)->take(10)->get(); //get next 10 rows

From laravel doc 5.2 https://laravel.com/docs/5.2/queries#ordering-grouping-limit-and-offset

skip / take

To limit the number of results returned from the query, or to skip a given number of results in the query (OFFSET), you may use the skip and take methods:

$users = DB::table('users')->skip(10)->take(5)->get();

In laravel 5.3 you can write (https://laravel.com/docs/5.3/queries#ordering-grouping-limit-and-offset)

$products = $art->products->offset(0)->limit(10)->get(); 

Use:

git remote prune <remote>

Where <remote> is a remote source name like origin or upstream.

Example: git remote prune origin

Generally you can't change styles programmatically; you can set the look of a screen, or part of a layout, or individual button in your XML layout using themes or styles. Themes can, however, be applied programmatically.

There is also such a thing as a StateListDrawable which lets you define different drawables for each state the your Button can be in, whether focused, selected, pressed, disabled and so on.

For example, to get your button to change colour when it's pressed, you could define an XML file called res/drawable/my_button.xml directory like this:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item
    android:state_pressed="true"
    android:drawable="@drawable/btn_pressed" />
  <item
    android:state_pressed="false"
    android:drawable="@drawable/btn_normal" />
</selector>

You can then apply this selector to a Button by setting the property android:background="@drawable/my_button".

I had a requirement to provide a report showing details by month where the date field was formatted as date & time, I simply changed the formatting of the date column to "General" and then used the following formula in a new column,

=CONCATENATE(YEAR(C2),MONTH(C2)) 

Language features:

Templates and Generic Code

• Template argument deduction for class templates

  • Like how functions deduce template arguments, now constructors can deduce the template arguments of the class
  • http://wg21.link/p0433r2 http://wg21.link/p0620r0 http://wg21.link/p0512r0

• template <auto>

  • Represents a value of any (non-type template argument) type.

• Non-type template arguments fixes

• template<template<class...>typename bob> struct foo {}

• ( Folding + ... + expressions ) and Revisions

• auto x{8}; is an int

• modernizing using with ... and lists

Lambda

• constexpr lambdas

  • Lambdas are implicitly constexpr if they qualify

• Capturing *this in lambdas

  • [*this]{ std::cout << could << " be " << useful << '\n'; }

Attributes

• [[fallthrough]], [[nodiscard]], [[maybe_unused]] attributes

• [[attributes]] on namespaces and enum { erator[[s]] }

• using in attributes to avoid having to repeat an attribute namespace.

• Compilers are now required to ignore non-standard attributes they don't recognize.

  • The C++14 wording allowed compilers to reject unknown scoped attributes.

Syntax cleanup

• Inline variables

  • Like inline functions
  • Compiler picks where the instance is instantiated
  • Deprecate static constexpr redeclaration, now implicitly inline.

• namespace A::B

• Simple static_assert(expression); with no string

• no throw unless throw(), and throw() is noexcept(true).

Cleaner multi-return and flow control

• Structured bindings

  • Basically, first-class std::tie with auto
  • Example:
    • const auto [it, inserted] = map.insert( {"foo", bar} );
    • Creates variables it and inserted with deduced type from the pair that map::insert returns.
  • Works with tuple/pair-likes & std::arrays and relatively flat structs
  • Actually named structured bindings in standard

• if (init; condition) and switch (init; condition)

  • if (const auto [it, inserted] = map.insert( {"foo", bar} ); inserted)
  • Extends the if(decl) to cases where decl isn't convertible-to-bool sensibly.

• Generalizing range-based for loops

  • Appears to be mostly support for sentinels, or end iterators that are not the same type as begin iterators, which helps with null-terminated loops and the like.

• if constexpr

  • Much requested feature to simplify almost-generic code.

Misc

• Hexadecimal float point literals

• Dynamic memory allocation for over-aligned data

• Guaranteed copy elision

  • Finally!
  • Not in all cases, but distinguishes syntax where you are "just creating something" that was called elision, from "genuine elision".

• Fixed order-of-evaluation for (some) expressions with some modifications

  • Not including function arguments, but function argument evaluation interleaving now banned
  • Makes a bunch of broken code work mostly, and makes .then on future work.

• Direct list-initialization of enums

• Forward progress guarantees (FPG) (also, FPGs for parallel algorithms)

  • I think this is saying "the implementation may not stall threads forever"?

• u8'U', u8'T', u8'F', u8'8' character literals (string already existed)

• "noexcept" in the type system

• __has_include

  • Test if a header file include would be an error
  • makes migrating from experimental to std almost seamless

• Arrays of pointer conversion fixes

• inherited constructors fixes to some corner cases (see P0136R0 for examples of behavior changes)

• aggregate initialization with inheritance.

• std::launder, type punning, etc

Library additions:

• std::any

  • Holds one of anything (that is copyable)

• std::string_view

  • Never take a string const& again. Also can make parsing a bajillion times faster.
  • "hello world"sv
  • constexpr char_traits

• std::byte off more than they could chew.

  • Neither an integer nor a character, just data

Invoke stuff

• std::invoke
  • Call any callable (function pointer, function, member pointer) with one syntax. From the standard INVOKE concept.
• std::apply
  • Takes a function-like and a tuple, and unpacks the tuple into the call.

• std::make_from_tuple, std::apply applied to object construction

• is_invocable, is_invocable_r, invoke_result

  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0077r2.html
  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0604r0.html
  • Deprecates result_of
  • is_invocable<Foo(Args...), R> is "can you call Foo with Args... and get something compatible with R", where R=void is default.
  • invoke_result<Foo, Args...> is std::result_of_t<Foo(Args...)> but apparently less confusing?

File System TS v1

• [class.path]

  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0358r1.html

• std::sample, sampling from a range?

Container Improvements

• try_emplace and insert_or_assign

  • gives better guarantees in some cases where spurious move/copy would be bad

• Splicing for map<>, unordered_map<>, set<>, and unordered_set<>

  • Move nodes between containers cheaply.
  • Merge whole containers cheaply.

• non-const .data() for string.

• non-member std::size, std::empty, std::data

  • like std::begin/end

• Minimal incomplete type support in containers

• Contiguous iterator "concept"

• constexpr iterators

• The emplace family of functions now returns a reference to the created object.

• weak_from_this and some fixed to shared from this

Other std datatype improvements:

Isocpp.org has has an independent list of changes since C++14; it has been partly pillaged.

Naturally TS work continues in parallel, so there are some TS that are not-quite-ripe that will have to wait for the next iteration. The target for the next iteration is C++20 as previously planned, not C++19 as some rumors implied. C++1O has been avoided.

Initial list taken from this reddit post and this reddit post, with links added via googling or from the above isocpp.org page.

Additional entries pillaged from SD-6 feature-test list.

clang's feature list and library feature list are next to be pillaged. This doesn't seem to be reliable, as it is C++1z, not C++17.

these slides had some features missing elsewhere.

While "what was removed" was not asked, here is a short list of a few things ((mostly?) previous deprecated) that are removed in C++17 from C++:

Removed:

• register, keyword reserved for future use
• bool b; ++b;
• trigraphs
  • if you still need them, they are now part of your source file encoding, not part of language
• ios aliases
• auto_ptr, old <functional> stuff, random_shuffle
• allocators in std::function

There were rewordings. I am unsure if these have any impact on code, or if they are just cleanups in the standard:

Papers not yet integrated into above:

• P0505R0 (constexpr chrono)

• P0418R2 (atomic tweaks)

• P0512R0 (template argument deduction tweaks)

• P0490R0 (structured binding tweaks)

• P0513R0 (changes to std::hash)

• P0502R0 (parallel exceptions)

• P0509R1 (updating restrictions on exception handling)

• P0012R1 (make exception specifications be part of the type system)

• P0510R0 (restrictions on variants)

• P0504R0 (tags for optional/variant/any)

• P0497R0 (shared ptr tweaks)

• P0508R0 (structured bindings node handles)

• P0521R0 (shared pointer use count and unique changes?)

Spec changes:

• exception specs and throw expressions

In my case the symbols I create (Tax1, Tax2, etc.) already had values but I wanted to use a loop and assign the symbols to another variable. So the above two answers gave me a way to accomplish this. This may be helpful in answering your question as the assignment of a value can take place anytime later.

output=NULL
for(i in 1:8){
   Tax=eval(as.symbol(paste("Tax",i,sep="")))
   L_Data1=L_Data_all[which(L_Data_all$Taxon==Tax[1] | L_Data_all$Taxon==Tax[2] | L_Data_all$Taxon==Tax[3] | L_Data_all$Taxon==Tax[4] | L_Data_all$Taxon==Tax[5]),]
   L_Data=L_Data1$Length[which(L_Data1$Station==Plant[1] | L_Data1$Station==Plant[2])]
   h=hist(L_Data,breaks=breaks,plot=FALSE)
   output=cbind(output,h$counts)
}

I've been using this little cheat for a while now. You might enjoy it. nest the table you want to center in another table:

<table height=100% width=100%>
<td align=center valign=center>

(add your table here)

</td>
</table>

the align and valign put the table exactly in the middle of the screen, no matter what else is going on.

That's the for each loop syntax. It is looping through each object in the collection returned by objectListing.getObjectSummaries().

1. First go to Recycle Bin of your local machine.
2. Your VS code deleted files is there in Recycle Bin.
3. So, Right click on deleted files and select-> Restore option then your deleted files will be automatically restored in your VS code.

this seems to do the trick:

function goBackOrGoToUrl() {    

    window.history.back();
    window.location = "http://example.com";

}

Call history.back() and then change the location. If the browser is able to go back in history it won't be able to get to the next statement. If it's not able to go back, it'll go to the location specified.

Just Use like that

Response.Clear();
Response.ContentType = "application/CSV";
Response.AddHeader("content-disposition", "attachment; filename=\"" + filename + ".csv\"");
Response.Write(t.ToString());
Response.End();

In my case the error 405 was invoked by static handler due to route ("api/images") conflicting with the folder of the same name ("~/images").

The TextBox has a property called ReadOnly. If you set that property to true then the TextBox will still be able to scroll but the user wont be able to change the value.

Solution for 2021.

Note: CRA. Initially the idea of ??using a third party library or ejecting app for alias seemed crazy to me. However, after 8 hours of searching (and trying variant with eject), it turned out that this option is the least painful.

Step 1.

yarn add --dev react-app-rewired react-app-rewire-alias

Step 2. Create config-overrides.js file in your project's root and fill it with :

const {alias} = require('react-app-rewire-alias')

module.exports = function override(config) {
  return alias({
    assets: './src/assets',
    '@components': './src/components',
  })(config)
}

Step 3. Fix your package.json file:

  "scripts": {
-   "start": "react-scripts start",
+   "start": "react-app-rewired start",
-   "build": "react-scripts build",
+   "build": "react-app-rewired build",
-   "test": "react-scripts test",
+   "test": "react-app-rewired test",
    "eject": "react-scripts eject"
}

If @declarations don't work, add them to the d.ts file. For example: '@constants': './src/constants', => add in react-app-env.d.ts declare module '@constants';

That is all. Now you can continue to use yarn or npm start/build/test commands as usual.

Full version in docs.

Note: The 'Using with ts / js config' part in docs did not work for me. The error "aliased imports are not supported" when building the project remained. So I used an easier way. Luckily it works.

You don't need to use complicated coding really!

Greyscale Hover:

-webkit-filter: grayscale(100%);

Greyscale "Hover-out":

-webkit-filter: grayscale(0%);

I simply made my css class have a separate hover class and added in the second greyscale. It's really simple if you really don't like complexity.

The main issue with your example that you can't implicitly convert Task<T> return types to the base T type. You need to use the Task.Result property. Note that Task.Result will block async code, and should be used carefully.

Try this instead:

public List<int> TestGetMethod()  
{  
    return GetIdList().Result;  
}

This is working code

protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            { 
                    DropDownList1.DataTextField = "user_name";
                    DropDownList1.DataValueField = "user_id";
                    DropDownList1.DataSource = getData();// get the data into the list you can set it
                    DropDownList1.DataBind();

    DropDownList1.SelectedIndex = DropDownList1.Items.IndexOf(DropDownList1.Items.FindByText("your default selected text"));
            }
        }

An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

Use MySQL's STR_TO_DATE() function to parse the string that you're attempting to insert:

INSERT INTO tblInquiry (fldInquiryReceivedDateTime) VALUES
  (STR_TO_DATE('5/15/2012 8:06:26 AM', '%c/%e/%Y %r'))

I've used it to send intraday trades between different fund management systems. If you want to learn more about what a great technology messaging is, I can thoroughly recommend the book "Enterprise Integration Patterns". There are some JMS examples for things like request/reply and publish/subscribe.

Messaging is an excellent tool for integration.

Use the wildcard "#" but beware that at some point you will have to somehow understand the data passing through the bus!

what worked for me was and is superfast is

import pandas as pd
import dask.dataframe as dd
import time
t=time.clock()
df_train = dd.read_csv('../data/train.csv', usecols=[col1, col2])
df_train=df_train.compute()
print("load train: " , time.clock()-t)

Another working solution is:

import pandas as pd 
from tqdm import tqdm

PATH = '../data/train.csv'
chunksize = 500000 
traintypes = {
'col1':'category',
'col2':'str'}

cols = list(traintypes.keys())

df_list = [] # list to hold the batch dataframe

for df_chunk in tqdm(pd.read_csv(PATH, usecols=cols, dtype=traintypes, chunksize=chunksize)):
    # Can process each chunk of dataframe here
    # clean_data(), feature_engineer(),fit()

    # Alternatively, append the chunk to list and merge all
    df_list.append(df_chunk) 

# Merge all dataframes into one dataframe
X = pd.concat(df_list)

# Delete the dataframe list to release memory
del df_list
del df_chunk

Note that one difference between git remote --prune and git fetch --prune is being fixed, with commit 10a6cc8, by Tom Miller (tmiller) (for git 1.9/2.0, Q1 2014):

When we have a remote-tracking branch named "frotz/nitfol" from a previous fetch, and the upstream now has a branch named "**frotz"**, fetch would fail to remove "frotz/nitfol" with a "git fetch --prune" from the upstream.
git would inform the user to use "git remote prune" to fix the problem.

So: when a upstream repo has a branch ("frotz") with the same name as a branch hierarchy ("frotz/xxx", a possible branch naming convention), git remote --prune was succeeding (in cleaning up the remote tracking branch from your repo), but git fetch --prune was failing.

Not anymore:

Change the way "fetch --prune" works by moving the pruning operation before the fetching operation.
This way, instead of warning the user of a conflict, it automatically fixes it.

The comment in your code is wrong. INADDR_ANY doesn't put server's IP automatically'. It essentially puts 0.0.0.0, for the reasons explained in mark4o's answer.

I think this code will do what you want. It stores the first row as a set of headers, then stores the rest in a data object which you can write to disk as JSON.

var XLSX = require('xlsx');
var workbook = XLSX.readFile('test.xlsx');
var sheet_name_list = workbook.SheetNames;
sheet_name_list.forEach(function(y) {
    var worksheet = workbook.Sheets[y];
    var headers = {};
    var data = [];
    for(z in worksheet) {
        if(z[0] === '!') continue;
        //parse out the column, row, and value
        var col = z.substring(0,1);
        var row = parseInt(z.substring(1));
        var value = worksheet[z].v;

        //store header names
        if(row == 1) {
            headers[col] = value;
            continue;
        }

        if(!data[row]) data[row]={};
        data[row][headers[col]] = value;
    }
    //drop those first two rows which are empty
    data.shift();
    data.shift();
    console.log(data);
});

prints out

    headline: 'team: sally pearson',
    location: 'Australia',
    'body text': 'majority have…',
    media: 'http://www.youtube.com/foo' },

Find the concerned service & delete it. Close regedit. Reboot the PC & Re-install the concerned service. Now the error should be gone.

What I was doing was starting a new activity and then closing the current activity. So, remember this simple rule:

finish()
startActivity<...>()

and not

startActivity<...>()
finish()

don't think you need quotations on this:

var child = $("this");

try:

var child = $(this);

Does the query has more than the parameter siteID, becouse if you want to run the query one parameter still isn't filled witch gives you the error

I faced this problem and solved it by running Eclipse as admin.

Try

console.log(_x000D_
  new Date().toLocaleString().slice(9, -3)_x000D_
  , new Date().toString().slice(16, -15)_x000D_
);

Update the master branch, which you need to do regardless.

Then, one of:

1. Rebase the old branch against the master branch. Solve the merge conflicts during rebase, and the result will be an up-to-date branch that merges cleanly against master.

2. Merge your branch into master, and resolve the merge conflicts.

3. Merge master into your branch, and resolve the merge conflicts. Then, merging from your branch into master should be clean.

None of these is better than the other, they just have different trade-off patterns.

I would use the rebase approach, which gives cleaner overall results to later readers, in my opinion, but that is nothing aside from personal taste.

To rebase and keep the branch you would:

git checkout <branch> && git rebase <target>

In your case, check out the old branch, then

git rebase master 

to get it rebuilt against master.

I just was in about the same situation a day ago, and here are my 2 cents:

1) I found arguably the shortest and most concise demonstration of multiple model entry in single form here: http://collingrady.wordpress.com/2008/02/18/editing-multiple-objects-in-django-with-newforms/ .

In a nutshell: Make a form for each model, submit them both to template in a single <form>, using prefix keyarg and have the view handle validation. If there is dependency, just make sure you save the "parent" model before dependant, and use parent's ID for foreign key before commiting save of "child" model. The link has the demo.

2) Maybe formsets can be beaten into doing this, but as far as I delved in, formsets are primarily for entering multiples of the same model, which may be optionally tied to another model/models by foreign keys. However, there seem to be no default option for entering more than one model's data and that's not what formset seems to be meant for.

Give a class .border-lb and give this CSS

.border-lb {border: 1px solid #ccc; border-width: 0 0 1px 1px;}

And the HTML

<table width="770">
  <tr>
    <td class="border-lb">picture (border only to the left and bottom ) </td>
    <td>text</td>
  </tr>
  <tr>
    <td>text</td>
    <td class="border-lb">picture (border only to the left and bottom) </td>
  </tr>
</table>

The recommended way is to use requests module:

#!/usr/bin/env python
import requests # $ python -m pip install requests
####from pip._vendor import requests # bundled with python

url = 'https://httpbin.org/hidden-basic-auth/user/passwd'
user, password = 'user', 'passwd'

r = requests.get(url, auth=(user, password)) # send auth unconditionally
r.raise_for_status() # raise an exception if the authentication fails

Here's a single source Python 2/3 compatible urllib2-based variant:

#!/usr/bin/env python
import base64
try:
    from urllib.request import Request, urlopen
except ImportError: # Python 2
    from urllib2 import Request, urlopen

credentials = '{user}:{password}'.format(**vars()).encode()
urlopen(Request(url, headers={'Authorization': # send auth unconditionally
    b'Basic ' + base64.b64encode(credentials)})).close()

Python 3.5+ introduces HTTPPasswordMgrWithPriorAuth() that allows:

..to eliminate unnecessary 401 response handling, or to unconditionally send credentials on the first request in order to communicate with servers that return a 404 response instead of a 401 if the Authorization header is not sent..

#!/usr/bin/env python3
import urllib.request as urllib2

password_manager = urllib2.HTTPPasswordMgrWithPriorAuth()
password_manager.add_password(None, url, user, password,
                              is_authenticated=True) # to handle 404 variant
auth_manager = urllib2.HTTPBasicAuthHandler(password_manager)
opener = urllib2.build_opener(auth_manager)

opener.open(url).close()

It is easy to replace HTTPBasicAuthHandler() with ProxyBasicAuthHandler() if necessary in this case.

Here I am going to explain not only the GROUP clause use, but also the Aggregate functions use.

The GROUP BY clause is used in conjunction with the aggregate functions to group the result-set by one or more columns. e.g.:

-- GROUP BY with one parameter:
SELECT column_name, AGGREGATE_FUNCTION(column_name)
FROM table_name
WHERE column_name operator value
GROUP BY column_name;

-- GROUP BY with two parameters:
SELECT
    column_name1,
    column_name2,
    AGGREGATE_FUNCTION(column_name3)
FROM
    table_name
GROUP BY
    column_name1,
    column_name2;

Remember this order:

1. SELECT (is used to select data from a database)

2. FROM (clause is used to list the tables)

3. WHERE (clause is used to filter records)

4. GROUP BY (clause can be used in a SELECT statement to collect data across multiple records and group the results by one or more columns)

5. HAVING (clause is used in combination with the GROUP BY clause to restrict the groups of returned rows to only those whose the condition is TRUE)

6. ORDER BY (keyword is used to sort the result-set)

You can use all of these if you are using aggregate functions, and this is the order that they must be set, otherwise you can get an error.

Aggregate Functions are:

MIN() returns the smallest value in a given column

MAX() returns the maximum value in a given column.

SUM() returns the sum of the numeric values in a given column

AVG() returns the average value of a given column

COUNT() returns the total number of values in a given column

COUNT(*) returns the number of rows in a table

SQL script examples about using aggregate functions:

Let's say we need to find the sale orders whose total sale is greater than $950. We combine the HAVING clause and the GROUP BY clause to accomplish this:

SELECT 
    orderId, SUM(unitPrice * qty) Total
FROM
    OrderDetails
GROUP BY orderId
HAVING Total > 950;

Counting all orders and grouping them customerID and sorting the result ascendant. We combine the COUNT function and the GROUP BY, ORDER BY clauses and ASC:

SELECT 
    customerId, COUNT(*)
FROM
    Orders
GROUP BY customerId
ORDER BY COUNT(*) ASC;

Retrieve the category that has an average Unit Price greater than $10, using AVG function combine with GROUP BY and HAVING clauses:

SELECT 
    categoryName, AVG(unitPrice)
FROM
    Products p
INNER JOIN
    Categories c ON c.categoryId = p.categoryId
GROUP BY categoryName
HAVING AVG(unitPrice) > 10;

Getting the less expensive product by each category, using the MIN function in a subquery:

SELECT categoryId,
       productId,
       productName,
       unitPrice
FROM Products p1
WHERE unitPrice = (
                SELECT MIN(unitPrice)
                FROM Products p2
                WHERE p2.categoryId = p1.categoryId)

The following statement groups rows with the same values in both categoryId and productId columns:

SELECT 
    categoryId, categoryName, productId, SUM(unitPrice)
FROM
    Products p
INNER JOIN
    Categories c ON c.categoryId = p.categoryId
GROUP BY categoryId, productId

You can give the background image in css :

#canvas { background:url(example.jpg) }

it will show you canvas back ground image

Be consistent and it doesn't matter which one. Also if for some reason you must interop with another program or tool using a certain DEBUG identifier it's easy to do

#ifdef THEIRDEBUG
#define MYDEBUG
#endif //and vice-versa

With Luxon (https://github.com/moment/luxon) :

import { DateTime } from 'luxon';
const week: number = DateTime.fromJSDate(new Date()).weekNumber;

It is powerful and dangerous. The biggest problem with fall-through is that it's not explicit. For example, if you come across frequently-edited code that has a switch with fall-throughs, how do you know that's intentional and not a bug?

Anywhere I use it, I ensure that it's properly commented:

switch($var) {
    case 'first':
        // Fall-through
    case 'second':
        i++;
        break;
 }

If you're displaying a user-readable file name, you do not want to use lastPathComponent. Instead, pass the full path to NSFileManager's displayNameAtPath: method. This basically does does the same thing, only it correctly localizes the file name and removes the extension based on the user's preferences.

If i understand your question you want to have the overlay just over the image and not cover everything?

I'd set the parent DIV (i renamed in content in the jsfiddle) position to relative, as the overlay should be positioned relative to this div not the window.

.content
{
  position: relative;
}

I did some pocking around and updated your fiddle to just have the overlay sized to the img which (I think) is what you want, let me know anyway :) http://jsfiddle.net/b9Vyw/

Here's something I use to transform an IEnumerable<T> into a DataTable that contains columns representing T's properties, with one row for each item in the IEnumerable:

public static DataTable ToDataTable<T>(IEnumerable<T> items)
{
    var table = CreateDataTableForPropertiesOfType<T>();
    PropertyInfo[] piT = typeof(T).GetProperties();
    foreach (var item in items)
    {
        var dr = table.NewRow();
        for (int property = 0; property < table.Columns.Count; property++)
        {
            if (piT[property].CanRead)
            {
                var value = piT[property].GetValue(item, null);
                if (piT[property].PropertyType.IsGenericType)
                {
                    if (value == null)
                    {
                        dr[property] = DBNull.Value;
                    }
                    else
                    {
                        dr[property] = piT[property].GetValue(item, null);
                    }
                }
                else
                {
                    dr[property] = piT[property].GetValue(item, null);
                }
            }
        }
        table.Rows.Add(dr);
    }
    return table;
}

public static DataTable CreateDataTableForPropertiesOfType<T>()
{
    DataTable dt = new DataTable();
    PropertyInfo[] piT = typeof(T).GetProperties();
    foreach (PropertyInfo pi in piT)
    {
        Type propertyType = null;
        if (pi.PropertyType.IsGenericType)
        {
            propertyType = pi.PropertyType.GetGenericArguments()[0];
        }
        else
        {
            propertyType = pi.PropertyType;
        }
        DataColumn dc = new DataColumn(pi.Name, propertyType);

        if (pi.CanRead)
        {
            dt.Columns.Add(dc);
        }
    }
    return dt;
}

This is "somewhat" overcomplicated, but it's actually quite good for seeing what the outcome is, as you can give it a List<T> of, for example:

public class Car
{
    string Make { get; set; }
    int YearOfManufacture {get; set; }
}

And you'll be returned a DataTable with the structure:

Make (string)
YearOfManufacture (int)

With one row per item in your List<Car>

public mySentences:Array<any> = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

OR

There are two ways to achieve that:

• Use -rpath linker option:

gcc XXX.c -o xxx.out -L$HOME/.usr/lib -lXX -Wl,-rpath=/home/user/.usr/lib

• Use LD_LIBRARY_PATH environment variable - put this line in your ~/.bashrc file:

  export LD_LIBRARY_PATH=/home/user/.usr/lib

This will work even for a pre-generated binaries, so you can for example download some packages from the debian.org, unpack the binaries and shared libraries into your home directory, and launch them without recompiling.

For a quick test, you can also do (in bash at least):

LD_LIBRARY_PATH=/home/user/.usr/lib ./xxx.out

which has the advantage of not changing your library path for everything else.

Of course, just assign seperate css classes to both tables.

<table class="style1"></table>
<table class="style2"></table>

.css

table.style1 { //your css here}
table.style2 { //your css here}

I have faced this problem, but configuging openssl (also for cli) did not help.

I have updated composer and this sloved my problem.

Just type:

$ php composer.phar self-update

or

$ composer selfupdate

Good luck!

If your looking to type up the message and then your bot will send it to the user, here is the code. It also has a role restriction on it :)

case 'dm':
  mentiondm = message.mentions.users.first();
  message.channel.bulkDelete(1);
  if (!message.member.roles.cache.some(role => role.name === "Owner")) return message.channel.send('Beep Boing: This command is way too powerful for you to use!');
  if (mentiondm == null) return message.reply('Beep Boing: No user to send message to!');
  mentionMessage = message.content.slice(3);
  mentiondm.send(mentionMessage);
  console.log('Message Sent!')
  break;

The answer in "peculiarity" is correct and directly answers the question. As TimF answered, since the first parameter is in quotes, it is treated as a window title.

Also note that the Virtual PC options are being treated as options to the 'start' command itself, and are not valid for 'start'. This is true for all versions of Windows that have the 'start' command.

This problem with 'start' treating the quoted parameter as a title is even more annoying that just the posted problem. If you run this:

start "some valid command with spaces"

You get a new command prompt window, with the obvious result for a window title. Even more annoying, this new window doesn't inherit customized font, colors or window size, it's just the default for cmd.exe.

$string = 'abc-123-xyz-789';
$exploded = explode('-', $string);
echo end($exploded);

EDIT::Finally got around to removing the E_STRICT issue
