You can use xargs which supports running many processes at a time. For your case it will be:

ls -1 /main/files | xargs -I {} -P 5 -n 1 rsync -avh /main/files/{} /main/filesTest/

There are several advantages to this sort of coding but for me the big win is, if you can return quick you can improve the speed of your application. IE I know that because of Precondition X that I can return quickly with an error. This gets rid of the error cases first and reduces the complexity of your code. In a lot of cases because the cpu pipeline can be now be cleaner it can stop pipeline crashes or switches. Secondly if you are in a loop, breaking or returning out quickly can save you a lots of cpu. Some programmers use loop invariants to do this sort of quick exit but in this you can broke your cpu pipeline and even create memory seek problem and mean the the cpu needs to load from outside cache. But basically I think you should do what you intended, that is end the loop or function not create a complex code path just to implement some abstract notion of correct code. If the only tool you have is a hammer then everything looks like a nail.

You can combine PIL's Image.thumbnail with sys.maxsize if your resize limit is only on one dimension (width or height).

For instance, if you want to resize an image so that its height is no more than 100px, while keeping aspect ratio, you can do something like this:

import sys
from PIL import Image

image.thumbnail([sys.maxsize, 100], Image.ANTIALIAS)

Keep in mind that Image.thumbnail will resize the image in place, which is different from Image.resize that instead returns the resized image without changing the original one.

I had a similar problem when using TFS 2017. I was not able to push or pull GIT repositories. Eventually I reinstalled TFS 2017, making sure that I installed TFS 2017 with an SSH Port different from 22 (in my case, I chose 8022). After that, push and pull became possible against TFS using SSH.

time.time() return the unix timestamp. you could use datetime library to get local time or UTC time.

import datetime

local_time = datetime.datetime.now()
print(local_time.strftime('%Y%m%d %H%M%S'))

utc_time = datetime.datetime.utcnow() 
print(utc_time.strftime('%Y%m%d %H%M%S'))

ACCESSING LOCAL WEBSITE WITH IIS without Physical Path Authentication

1. Make sure you have installed URL Rewrite to your IIS Manager

2. Open the URL Rewrite application then navigate to Inbound Rules>Import Rules

3. To import the rule, click the browse button then locate your .htaccess file then click import button

4. The text labeled with red are errors that are not accepted by IIS, so you have to remove them by clicking the errors in the converted rules and remove the text from the rewrite rules. Once you have get rid of the errors Click the APPLY button located at the top right corner. Then try to access your site without engaging users into the pool auth.

I hope it helps. That's what I did.

Note that once you have imported the google-play-services_lib project into your IDE, you will also need to add google-play-services.jar to: Project=>Properties=>Java build path=>Libraries=>Add JARs

You should add the following lines in your gradle build file (build.gradle)

dependencies { 
     compile files('/usr/share/stuff')
     ..
}

PHP does not have permissions to write on /tmp directory. You need to use chmod command to open /tmp permissions.

You can create a utility class (which cannot have instances created) by declaring an enum type with no instances. i.e. you are specificly declaring that there are no instances.

public enum MyUtilities {;
   public static void myMethod();
}

ArrayList inherits its toString()-method from AbstractCollection, ie:

public String toString() {
    Iterator<E> i = iterator();
    if (! i.hasNext())
        return "[]";

    StringBuilder sb = new StringBuilder();
    sb.append('[');
    for (;;) {
        E e = i.next();
        sb.append(e == this ? "(this Collection)" : e);
        if (! i.hasNext())
            return sb.append(']').toString();
        sb.append(", ");
    }
}

Building the string yourself will be far more efficient.

If you really want to aggregate the strings beforehand in some sort of List, you should provide your own method to efficiently join them, e.g. like this:

static String join(Collection<?> items, String sep) {
    if(items.size() == 0)
        return "";

    String[] strings = new String[items.size()];
    int length = sep.length() * (items.size() - 1);

    int idx = 0;
    for(Object item : items) {
        String str = item.toString();
        strings[idx++] = str;
        length += str.length();
    }

    char[] chars = new char[length];
    int pos = 0;

    for(String str : strings) {
        str.getChars(0, str.length(), chars, pos);
        pos += str.length();

        if(pos < length) {
            sep.getChars(0, sep.length(), chars, pos);
            pos += sep.length();
        }
    }

    return new String(chars);
}

Deep copying can only be done with each class's consent. If you have control over the class hierarchy then you can implement the clonable interface and implement the Clone method. Otherwise doing a deep copy is impossible to do safely because the object may also be sharing non-data resources (e.g. database connections). In general however deep copying is considered bad practice in the Java environment and should be avoided via the appropriate design practices.

Because it has already been pushed, you shouldn't directly manipulate history. git revert will revert specific changes from a commit using a new commit, so as to not manipulate commit history.

 class Program
{
    static void Main(string[] args)
    {
        int[] arr = new int[] { 10, 20,20, 30, 10, 50 ,50,9};
        List<int> listadd = new List<int>();

        for (int i=0; i <arr.Length;i++)
        {
           int count = 0;
            int flag = 0;

            for(int j=0; j < arr.Length; j++)
            {
                if (listadd.Contains(arr[i]) == false)
                {


                    if (arr[i] == arr[j])
                    {
                        count++;
                    }

                } 

                else
                {
                    flag = 1;
                }

            }
            listadd.Add(arr[i]);
            if(flag!=1)
            Console.WriteLine("No of occurance {0} \t{1}", arr[i], count);
        }
        Console.ReadLine();

    }
}

String path = "Your_Path";
File f = new File(path);

if (f.isDirectory()){



  }else if(f.isFile()){



  }

Building on the above, if anyone needs to handle errors in the write/read streams, I used this version. Note the stream.read() in case of a write error, it's required so we can finish reading and trigger close on the read stream.

var download = function(uri, filename, callback){
  request.head(uri, function(err, res, body){
    if (err) callback(err, filename);
    else {
        var stream = request(uri);
        stream.pipe(
            fs.createWriteStream(filename)
                .on('error', function(err){
                    callback(error, filename);
                    stream.read();
                })
            )
        .on('close', function() {
            callback(null, filename);
        });
    }
  });
};

If you don't like "verbosity" you can always wrap your code in a short method:

private void msgbox(String s){
   JOptionPane.showMessageDialog(null, s);
}

and the usage:

msgbox("don't touch that!");

Here's the script, rewritten to use the suggestions above and a change to your no-cache method.

<?php
// Simpler way of making sure all no-cache headers get sent
// and understood by all browsers, including IE.
session_cache_limiter('nocache');
header('Expires: ' . gmdate('r', 0));

header('Content-type: application/json');

// set to return response=error
$arr = array ('response'=>'error','comment'=>'test comment here');
echo json_encode($arr);
?>

//the script above returns this:
{"response":"error","comment":"test comment here"}

<script type="text/javascript">
$.ajax({
    type: "POST",
    url: "process.php",
    data: dataString,
    dataType: "json",
    success: function (data) {
        if (data.response == 'captcha') {
            alert('captcha');
        } else if (data.response == 'success') {
            alert('success');
        } else {
            alert('sorry there was an error');
        }
    }

}); // Semi-colons after all declarations, IE is picky on these things.
</script>

The main issue here was that you had a typo in the JSON you were returning ("resonse" instead of "response". This meant that you were looking for the wrong property in the JavaScript code. One way of catching these problems in the future is to console.log the value of data and make sure the property you are looking for is there.

Learning how to use the Chrome debugger tools (or similar tools in Firefox/Safari/Opera/etc.) will also be invaluable.

OAuth has two scenarios in real mode. The normal and default style of access is called online. In some cases, your application may need to access a Google API when the user is not present,It's offline scenarios . a refresh token is obtained in offline scenarios during the first authorization code exchange.

So you can get refersh_token is some scenarios ,not all.

you can have the content in https://developers.google.com/identity/protocols/OAuth2WebServer#offline .

I've created a little Powershell function to emulate MSDOS pause. This handles whether running Powershell ISE or non ISE. (ReadKey does not work in powershell ISE). When running Powershell ISE, this function opens a Windows MessageBox. This can sometimes be confusing, because the MessageBox does not always come to the forefront. Anyway, here it goes:

Usage: pause "Press any key to continue"

Function definition:

Function pause ($message)
{
    # Check if running Powershell ISE
    if ($psISE)
    {
        Add-Type -AssemblyName System.Windows.Forms
        [System.Windows.Forms.MessageBox]::Show("$message")
    }
    else
    {
        Write-Host "$message" -ForegroundColor Yellow
        $x = $host.ui.RawUI.ReadKey("NoEcho,IncludeKeyDown")
    }
}

jQuery:

$(window).unload( function () { alert("Bye now!"); } );

or javascript:

window.onunload = function(){alert("Bye now!");}

If your url is http://localhost:8080/context path?msisdn={msisdn}&email={email}

then

Map<String,Object> queryParams=new HashMap<>();
queryParams.put("msisdn",your value)
queryParams.put("email",your value)

works for resttemplate exchange method as described by you

-fix- because you want to change from radians to degrees, it is actually rad=deg * math.pi /180 and not deg*180/math.pi

import math
x=1                # in deg
x = x*math.pi/180  # convert to rad
y = math.cos(x)    # calculate in rad

print y

in 1 line it can be like this

y=math.cos(1*math.pi/180)

Run cmd and then run node server.js. In your example, you are trying to use the REPL to run your command, which is not going to work. The ellipsis is node.js expecting more tokens before closing the current scope (you can type code in and run it on the fly here)

VBA does not have an internal implementation of a dictionary, but from VBA you can still use the dictionary object from MS Scripting Runtime Library.

Dim d
Set d = CreateObject("Scripting.Dictionary")
d.Add "a", "aaa"
d.Add "b", "bbb"
d.Add "c", "ccc"

If d.Exists("c") Then
    MsgBox d("c")
End If

Typescript does not yet support Map.

ES6 Compatibility Table

Your sys.path is kind of unusual, as each entry is prefixed with /usr/intel. I guess numpy is installed in the usual non-prefixed place, e.g. it. /usr/share/pyshared/numpy on my Ubuntu system.

Try find / -iname '*numpy*'

You can do like

$result= file_get_contents(site_url('[ADDRESS TO CONTROLLER FUNCTION]'));

Replace [ADDRESS TO CONTROLLER FUNCTION] by the way we use in site_url();

You need to echo output in controller function instead of return.

I think that in real world scenarios a simple click handler is probably better than over-complicated command-based systems but you can do something like that:

using RelayCommand from this article http://msdn.microsoft.com/en-us/magazine/dd419663.aspx

public class MyCommands
{
    public static readonly ICommand CloseCommand =
        new RelayCommand( o => ((Window)o).Close() );
}

<Button Content="Close Window"
        Command="{X:Static local:MyCommands.CloseCommand}"
        CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, 
                           AncestorType={x:Type Window}}}"/>

Yes, to make it run in the background create a shortcut to the batch file and go into the properties. I'm on a Linux machine ATM but I believe the option you are wanting is in the advanced tab.

You can also run your batch script through a vbs script like this:

'HideBat.vbs
CreateObject("Wscript.Shell").Run "your_batch_file.bat", 0, True

This will execute your batch file with no cmd window shown.

In Widows it is working for me. Control Shift F and then it opens a search window at the bottom. Make sure you expand the bottom area to see the new search window.

When you use a command substitution (i.e., the $(...) construct), you are creating a subshell. Subshells inherit variables from their parent shells, but this only works one way: A subshell cannot modify the environment of its parent shell.

Your variable e is set within a subshell, but not the parent shell. There are two ways to pass values from a subshell to its parent. First, you can output something to stdout, then capture it with a command substitution:

myfunc() {
    echo "Hello"
}

var="$(myfunc)"

echo "$var"

The above outputs:

Hello

For a numerical value in the range of 0 through 255, you can use return to pass the number as the exit status:

mysecondfunc() {
    echo "Hello"
    return 4
}

var="$(mysecondfunc)"
num_var=$?

echo "$var - num is $num_var"

This outputs:

Hello - num is 4

Override the functions setUpdatedAt() and getUpdatedAtColumn() in your model

public function setUpdatedAt($value)
{
   //Do-nothing
}

public function getUpdatedAtColumn()
{
    //Do-nothing
}

None of these solutions worked for me. But I was able to get vertical centering by using <div class="form-row align-items-center"> for each form row, per the Bootstrap examples.

Besides the session cookie (which is kind of standard), I don't want to use extra cookies.

I found a solution which works for me when building a Single Page Web Application (SPA), with many AJAX requests. Note: I am using server side Java and client side JQuery, but no magic things so I think this principle can be implemented in all popular programming languages.

My solution without extra cookies is simple:

Client Side

Store the CSRF token which is returned by the server after a succesful login in a global variable (if you want to use web storage instead of a global thats fine of course). Instruct JQuery to supply a X-CSRF-TOKEN header in each AJAX call.

The main "index" page contains this JavaScript snippet:

// Intialize global variable CSRF_TOKEN to empty sting. 
// This variable is set after a succesful login
window.CSRF_TOKEN = '';

// the supplied callback to .ajaxSend() is called before an Ajax request is sent
$( document ).ajaxSend( function( event, jqXHR ) {
    jqXHR.setRequestHeader('X-CSRF-TOKEN', window.CSRF_TOKEN);
}); 

Server Side

On successul login, create a random (and long enough) CSRF token, store this in the server side session and return it to the client. Filter certain (sensitive) incoming requests by comparing the X-CSRF-TOKEN header value to the value stored in the session: these should match.

Sensitive AJAX calls (POST form-data and GET JSON-data), and the server side filter catching them, are under a /dataservice/* path. Login requests must not hit the filter, so these are on another path. Requests for HTML, CSS, JS and image resources are also not on the /dataservice/* path, thus not filtered. These contain nothing secret and can do no harm, so this is fine.

@WebFilter(urlPatterns = {"/dataservice/*"})
...
String sessionCSRFToken = req.getSession().getAttribute("CSRFToken") != null ? (String) req.getSession().getAttribute("CSRFToken") : null;
if (sessionCSRFToken == null || req.getHeader("X-CSRF-TOKEN") == null || !req.getHeader("X-CSRF-TOKEN").equals(sessionCSRFToken)) {
    resp.sendError(401);
} else
    chain.doFilter(request, response);
}   

^{Worth mentioning}

If you want to have a list of all classes under some package, you can use Reflection the following way:

List<Class> myTypes = new ArrayList<>();

Reflections reflections = new Reflections("com.package");
for (String s : reflections.getStore().get(SubTypesScanner.class).values()) {
    myTypes.add(Class.forName(s));
}

This will create a list of classes that later you can use them as you wish.

There is another option that worked for me:

Subclass UITextField and overwrite:

- (void)drawTextInRect:(CGRect)rect

In this method you can for example:

    NSDictionary *attributes = @{ NSFontAttributeName : self.font,
                                  NSForegroundColorAttributeName : self.textColor };

    [self.text drawInRect:verticalAlignedRect withAttributes:attributes];

This code will render the text using as many lines as required if the rect has enough space. You could specify any other attribute depending on your needs.

Do not use:

self.defaultTextAttributes

which will force one line text rendering

Try that - will set it globally:

npm config set msvs_version 2012 --global

I had the same problem but finally I found the way.

Here is the walk through:

1- Install VLC on your computer (SERVER) and go to Media->Streaming (Ctrl+S)

2- Select a file to stream or if you want to stream your webcam or... click on "Capture Device" tab and do the configuration and finally click on "Stream" button.

3- Here you should do the streaming server configuration, just go to "Option" tab and paste the following command:

:sout=#transcode{vcodec=mp4v,vb=400,fps=10,width=176,height=144,acodec=mp4a,ab=32,channels=1,samplerate=22050}:rtp{sdp=rtsp://YOURCOMPUTER_SERVER_IP_ADDR:5544/}

NOTE: Replace YOURCOMPUTER_SERVER_IP_ADDR with your computer IP address or any server which is running VLC...

NOTE: You can see, the video codec is MP4V which is supported by android.

4- go to eclipse and create a new project for media playbak. create a VideoView object and in the OnCreate() function write some code like this:

mVideoView = (VideoView) findViewById(R.id.surface_view);

mVideoView.setVideoPath("rtsp://YOURCOMPUTER_SERVER_IP_ADDR:5544/");
mVideoView.setMediaController(new MediaController(this));

5- run the apk on the device (not simulator, i did not check it) and wait for the playback to be started. please consider the buffering process will take about 10 seconds...

Question: Anybody know how to reduce buffering time and play video almost live ?

With a \ before a Class declaration you are calling the root namespace:

$now = \Carbon\Carbon::now()->timestamp;

otherwise it looks for it at the current namespace declared at the beginning of the class. other solution is to use it:

use Carbon\Carbon
$now = Carbon::now()->timestamp;

you can even assign it an alias:

use Carbon\Carbon as Time;
$now = Time::now()->timestamp;

hope it helps.

First, one thing to recognize about OS X is that it is built on Unix. This is where the .bash_profile comes in. When you start the Terminal app in OS X you get a bash shell by default. The bash shell comes from Unix and when it loads it runs the .bash_profile script. You can modify this script for your user to change your settings. This file is located at:

~/.bash_profile

Update for Mavericks

OS X Mavericks does not use the environment.plist - at least not for OS X windows applications. You can use the launchd configuration for windowed applications. The .bash_profile is still supported since that is part of the bash shell used in Terminal.

Lion and Mountain Lion Only

OS X windowed applications receive environment variables from the your environment.plist file. This is likely what you mean by the ".plist" file. This file is located at:

~/.MacOSX/environment.plist

If you make a change to your environment.plist file then OS X windows applications, including the Terminal app, will have those environment variables set. Any environment variable you set in your .bash_profile will only affect your bash shells.

Generally I only set variables in my .bash_profile file and don't change the .plist file (or launchd file on Mavericks). Most OS X windowed applications don't need any custom environment. Only when an application actually needs a specific environment variable do I change the environment.plist (or launchd file on Mavericks).

It sounds like what you want is to change the environment.plist file, rather than the .bash_profile.

One last thing, if you look for those files, I think you will not find them. If I recall correctly, they were not on my initial install of Lion.

Edit: Here are some instructions for creating a plist file.

1. Open Xcode
2. Select File -> New -> New File...
3. Under Mac OS X select Resources
4. Choose a plist file
5. Follow the rest of the prompts

To edit the file, you can Control-click to get a menu and select Add Row. You then can add a key value pair. For environment variables, the key is the environment variable name and the value is the actual value for that environment variable.

Once the plist file is created you can open it with Xcode to modify it anytime you wish.

Note that with Doxygen release 1.8.0 you can also add Markdown formated pages. For this to work you need to create pages with a .md or .markdown extension, and add the following to the config file:

INPUT += your_page.md
FILE_PATTERNS += *.md *.markdown

See http://www.doxygen.nl/manual/markdown.html#md_page_header for details.

Basically you need following things to make location detector android app

• Location Listener, which detect current location
• Marker to add and animate when person moves
• Polyline to add path on person's movement
• Services for sending and receiving location
• Rest API / Firebase Realtime Database to store and fetch locations

Now if you write each of these module yourself then it needs much time and efforts. So it would be better to use ready resources that are being maintained already.

Using all these resources, you will be able to create an flawless android location detection app.

1. Location Listening

You will first need to listen for current location of user. You can use any of below libraries to quick start.

Google Play Location Samples

This library provide last known location, location updates

Location Manager

With this library you just need to provide a Configuration object with your requirements, and you will receive a location or a fail reason with all the stuff are described above handled.

Live Location Sharing

Use this open source repo of the Hypertrack Live app to build live location sharing experience within your app within a few hours. HyperTrack Live app helps you share your Live Location with friends and family through your favorite messaging app when you are on the way to meet up. HyperTrack Live uses HyperTrack APIs and SDKs.

2. Markers Library

Google Maps Android API utility library

• Marker clustering — handles the display of a large number of points
• Heat maps — display a large number of points as a heat map
• IconGenerator — display text on your Markers
• Poly decoding and encoding — compact encoding for paths, interoperability with Maps API web services
• Spherical geometry — for example: computeDistance, computeHeading, computeArea
• KML — displays KML data
• GeoJSON — displays and styles GeoJSON data

3. Polyline Libraries

DrawRouteMaps

If you want to add route maps feature in your apps you can use DrawRouteMaps to make you work more easier. This is lib will help you to draw route maps between two point LatLng.

trail-android

Simple, smooth animation for route / polylines on google maps using projections. (WIP)

Google-Directions-Android

This project allows you to calculate the direction between two locations and display the route on a Google Map using the Google Directions API.

A map demo app for quick start with maps

I am working in Windows 7 with Python IDLE. I have two programs,

# progA
while True:
    m = input('progA is running ')
    print (m)

and

# progB
while True:
    m = input('progB is running ')
    print (m)

I open up IDLE and then open file progA.py. I run the program, and when prompted for input I enter "b" + <Enter> and then "c" + <Enter>

I am looking at this window:

Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 17:26:49) [MSC v.1900 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> 
= RESTART: C:\Users\Mike\AppData\Local\Programs\Python\Python36-32\progA.py =
progA is running b
b
progA is running c
c
progA is running 

Next, I go back to Windows Start and open up IDLE again, this time opening file progB.py. I run the program, and when prompted for input I enter "x" + <Enter> and then "y" + <Enter>

I am looking at this window:

Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 17:26:49) [MSC v.1900 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> 
= RESTART: C:\Users\Mike\AppData\Local\Programs\Python\Python36-32\progB.py =
progB is running x
x
progB is running y
y
progB is running 

Now two IDLE Python 3.6.3 Shell programs are running at the same time, one shell running progA while the other one is running progB.

Use android vollley, it is very fast and you can betterm manipulate requests. Send post request using Volley and receive in PHP

Basically, you will create a map with key-value params for the php request(POST/GET), the php will do the desired processing and you will return the data as JSON(json_encode()). Then you can either parse the JSON as needed or use GSON from Google to let it do the parsing.

With .Net Framework 4.5 (using ZipArchive):

using (ZipArchive zip = ZipFile.Open(zipfile, ZipArchiveMode.Read))
    foreach (ZipArchiveEntry entry in zip.Entries)
        if(entry.Name == "myfile")
            entry.ExtractToFile("myfile");

Find "myfile" in zipfile and extract it.

Vector is a broken class that is not threadsafe, despite it being "synchronized" and is only used by students and other inexperienced programmers.

ArrayList is the go-to List implementation used by professionals and experienced programmers.

Professionals wanting a threadsafe List implementation use a CopyOnWriteArrayList.

Put the image — let's say it's width is 140px — inside of a link:

<a><img src='image link' style='width: 140px'></a>

Next, put the caption in a and give it a width less than your image, while centering it:

<a>
  <img src='image link' style='width: 140px'>
  <div style='width: 130px; text-align: center;'>I just love to visit this most beautiful place in all the world.</div>
</a>

Next, in the link tag, style the link so that it no longer looks like a link. You can give it any color you want, but just remove any text decoration your links may carry.

<a style='text-decoration: none; color: orange;'>
  <img src='image link' style='width: 140px'>
  <div style='width: 130px; text-align: center;'>I just love to visit this most beautiful place in all the world.</div>
</a>

I wrapped the image with it's caption in a link so that no text could push the caption out of the way: The caption is tied to the picture by the link. Here's an example: http://www.alphaeducational.com/p/okay.html

1. First, launch your Safari browser from the Home screen and go to the webpage that you want to view full screen.

2. After locating the webpage, tap on the arrow icon at the top of your screen.

3. In the drop-down menu, tap on the Add to Home Screen option.

4. The Add to Home window should be displayed. You can customize the description that will appear as a title on the home screen of your iPad. When you are done, tap on the Add button.

5. A new icon should now appear on your home screen. Tapping on the icon will open the webpage in the fullscreen mode.

Note: The icon on your iPad home screen only opens the bookmarked page in the fullscreen mode. The next page you visit will be contain the Safari address and title bars. This way of playing your webpage or HTML5 presentation in the fullscreen mode works if the source code of the webpage contains the following tag:

<meta name="apple-mobile-web-app-capable" content="yes">

You can add this tag to your webpage using a third-party tool, for example iWeb SEO Tool or any other you like. Please note that you need to add the tag first, refresh the page and then add a bookmark to your home screen.

As of Select2 4.1, they've removed support for .enable

In java there is a length field that you can use on any array to find out it's size:

    String[] s = new String[10];
    System.out.println(s.length);

Since the only noise terminals tend to make is the bell and if you want it off everywhere, the very simplest way to do it for bash on Windows:

1. Mash backspace a bunch at the prompt
2. Right click sound icon and choose Open Volume Mixer
3. Lower volume on Console Window Host to zero

You should not use space character while naming database objects. Even though it's possible by using double quotes(quoted identifiers), CREATE TABLE "chartered flight" ..., it's not recommended. Take a closer look here

Honestly, I've always been happy with emacs. Then again, I started out using emacs, so I've no doubt that it colours my perceptions. Still, it gives syntax highlighting and formatting, and can easily be configured to build the LaTeX. Check out the TeX mode.

For modern browsers, use td:nth-child(2) for the second td, and td:nth-child(3) for the third. Remember that these retrieve the second and third td for every row.

If you need compatibility with IE older than version 9, use sibling combinators or JavaScript as suggested by Tim. Also see my answer to this related question for an explanation and illustration of his method.

Works like a charm!

.imageClass {
  -webkit-filter: drop-shadow(12px 12px 7px rgba(0,0,0,0.5));
}

Voila! That's it! Obviously this won't work in ie, but who cares...

I got sane error with LoginController, which I used in main index.html. I found two ways to resolve:

1. setting $controllerProvider.allowGlobals(), I found that comment in Angular change-list "this option might be handy for migrating old apps, but please don't use it in new ones!" original comment on Angular

   app.config(['$controllerProvider', function($controllerProvider) { $controllerProvider.allowGlobals(); }]);

2. wrong contructor of registering controller

before

LoginController.$inject = ['$rootScope', '$scope', '$location'];

now

app.controller('LoginController', ['$rootScope', '$scope', '$location', LoginController]);

'app' come from app.js

var MyApp = {};
var app = angular.module('MyApp ', ['app.services']);
var services = angular.module('app.services', ['ngResource', 'ngCookies', 'ngAnimate', 'ngRoute']);

Have a look at what happens if you run javaws.exe directly from the command line.

There is no Swift preprocessor. (For one thing, arbitrary code substitution breaks type- and memory-safety.)

Swift does include build-time configuration options, though, so you can conditionally include code for certain platforms or build styles or in response to flags you define with -D compiler args. Unlike with C, though, a conditionally compiled section of your code must be syntactically complete. There's a section about this in Using Swift With Cocoa and Objective-C.

For example:

#if os(iOS)
    let color = UIColor.redColor()
#else
    let color = NSColor.redColor()
#endif

Given that all the dataframes have the same columns, you can simply concat them:

import pandas as pd
df = pd.concat(list_of_dataframes)

Everything was too difficult or badly documented so I solved this with a simple script swagger-yaml-to-html.py, which works like this

python swagger-yaml-to-html.py < /path/to/api.yaml > doc.html

This is for YAML but modifying it to work with JSON is also trivial.

If you download the latest version of Adobe Acrobat Reader, it will tell you if your pdf is PDF/A compliant. Just open the PDF file and a big blue marking should appear.

OpenOffice supports PDF/A. For some reason "PDF/A-1" is called

"SelectPdfVersion"

The different values can be

0 = PDFXNONE
1 = PDFX1A2001
2 = PDFX32002
3 = PDFA1A
4 = PDFA1B

You set

FilterData

HashMap('SelectPdfVersion',1) //1 for PDFX1A2001

Previous answers pretty much summarize the possible ways of accomplishing this task.

However, I suggest a modification for those who don't care about counting the duplicates, but do care about order.

my @record = qw( yeah I mean uh right right uh yeah so well right I maybe );
my %record;
print grep !$record{$_} && ++$record{$_}, @record;

Note that the previously suggested grep !$seen{$_}++ ... increments $seen{$_} before negating, so the increment occurs regardless of whether it has already been %seen or not. The above, however, short-circuits when $record{$_} is true, leaving what's been heard once 'off the %record'.

You could also go for this ridiculousness, which takes advantage of autovivification and existence of hash keys:

...
grep !(exists $record{$_} || undef $record{$_}), @record;

That, however, might lead to some confusion.

And if you care about neither order or duplicate count, you could for another hack using hash slices and the trick I just mentioned:

...
undef @record{@record};
keys %record; # your record, now probably scrambled but at least deduped

Consider:

Function GetFolder() As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select a Folder"
        .AllowMultiSelect = False
        .InitialFileName = Application.DefaultFilePath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    GetFolder = sItem
    Set fldr = Nothing
End Function

This code was adapted from Ozgrid

and as jkf points out, from Mr Excel

Where do these characters occur? Do you see them if you examine the XML data in, say, notepad? Or do you see them when examining the XML data in the debugger. If it is the latter, they are only escape characters for the " characters, and so part of the actual XML data.

You'll need to write sort of ObjectConverter for this. This is doable if you have both the object which you want to convert and you know the target class to which you'd like to convert to. In this particular case you can get the target class by Field#getDeclaringClass().

You can find here an example of such an ObjectConverter. It should give you the base idea. If you want more conversion possibilities, just add more methods to it with the desired argument and return type.

In my case setting width to all divs helped:

.page-content div {
    width: auto !important;
    max-width: 99%;
}

You're already prepending the hash sign in your showDialog() function, and you're missing single quotes in your second code snippet. You should also return false from the handler to prevent a postback from occurring. Try:

<asp:Button ID="ButtonAdd" runat="server" Text="Add"
    OnClientClick="showDialog('<%=addPerson.ClientID %>'); return false;" />

1. You seem to be including one C file from anther. #include should normally be used with header files only.

2. Within the definition of struct ast_node you refer to struct AST_NODE, which doesn't exist. C is case-sensitive.

This one works for me.

It is simpler then Rj0078's answer in this question (https://stackoverflow.com/a/42556648/11211963), but that one is worked as well.

It shows a dialog like this:

(Written in Kotlin)

    googleApiClient = GoogleApiClient.Builder(context!!)
        .addApi(LocationServices.API).build()
    googleApiClient!!.connect()
    locationRequest = LocationRequest.create()
    locationRequest!!.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
    locationRequest!!.interval = 30 * 1000.toLong()
    locationRequest!!.fastestInterval = 5 * 1000.toLong()

    val builder = LocationSettingsRequest.Builder()
        .addLocationRequest(locationRequest!!)
    builder.setAlwaysShow(true)

    result =
       LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build())
    result!!.setResultCallback { result ->
        val status: Status = result.status
        when (status.statusCode) {
            LocationSettingsStatusCodes.SUCCESS -> {
               // Do something
            }
            LocationSettingsStatusCodes.RESOLUTION_REQUIRED ->
                try {
                    startResolutionForResult(),
                    status.startResolutionForResult(
                        activity,
                        REQUEST_LOCATION
                    )
                } catch (e: SendIntentException) {
                }
            LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE -> {
                // Do something
            }
        }
    }

You could start by taking the Cartesian product of df1.col1 and df2.col3, then merge back to df1 to get col2.

Here's a general Cartesian product function which takes a dictionary of lists:

def cartesian_product(d):
    index = pd.MultiIndex.from_product(d.values(), names=d.keys())
    return pd.DataFrame(index=index).reset_index()

Apply as:

res = cartesian_product({'col1': df1.col1, 'col3': df2.col3})
pd.merge(res, df1, on='col1')
#  col1 col3 col2
# 0   1    5    3
# 1   1    6    3
# 2   2    5    4
# 3   2    6    4

Don't look any further:

0 3 * * * /usr/bin/env bash -c 'cd /home/user/project && source /home/user/project/env/bin/activate && ./manage.py command arg' > /dev/null 2>&1

Generic approach:

* * * * * /usr/bin/env bash -c 'YOUR_COMMAND_HERE' > /dev/null 2>&1

The beauty about this is you DO NOT need to change the SHELL variable for crontab from sh to bash

Either use a real fully qualified domain name (like dev.yourdomain.com) that pointing to 127.0.0.1 or try editing the proper hosts file (usually /etc/hosts in *nix environments).

How about just using

void feedInputToOutput(InputStream in, OutputStream out) {
   IOUtils.copy(in, out);
}

and be done with it?

I worked on both Travis and Jenkins: I will list down some of the features of both:

Setup CI for a project

Travis comes in first place. It's very easy to setup. Takes less than a minute to setup with GitHub.

1. Login to GitHub
2. Create Web Hook for Travis.
3. Return to Travis, and login with your GitHub credentials
4. Sync your GitHub repo and enable Push and Pull requests.

Jenkins:

1. Create an Environment (Master Jenkins)
2. Create web hooks
3. Configure each job (takes time compare to Travis)

Re-running builds

Travis: Anyone with write access on GitHub can re-run the build by clicking on `restart build

Jenkins: Re-run builds based on a phrase. You provide phrase text in PR/commit description, like reverify jenkins.

Controlling environment

Travis: Travis provides hosted environment. It installs required software for every build. It’s a time-consuming process.

Jenkins: One-time setup. Installs all required software on a node/slave machine, and then builds/tests on a pre-installed environment.

Build Logs:

Travis: Supports build logs to place in Amazon S3.

Jenkins: Easy to setup with build artifacts plugin.

AutoSize, Minimum, Maximum does not give flexibility. Use multiline and handle the enter key event and suppress the keypress. Works great.

textBox1.Multiline = true;

 private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                e.Handled = true;
                e.SuppressKeyPress = true;
            }
        }

You can cast the numerator or the denominator to float...

int operations usually return int, so you have to change one of the operanding numbers.

FatJar can help you in this case.

In addition to the"Export as Jar" function which is included to Eclipse the Plug-In bundles all dependent JARs together into one executable jar.
The Plug-In adds the Entry "Build Fat Jar" to the Context-Menu of Java-projects

This is useful if your final exported jar includes other external jars.

If you have Ganymede, the Export Jar dialog is enough to export your resources from your project.

After Ganymede, you have:

I was successful in doing this using file://, but with one additional slash to denote an absolute path.

git clone file:///cygdrive/c/path/to/repository/

In my case I'm using Git on Cygwin for Windows, which you can see because of the /cygdrive/c part in my paths. With some tweaking to the path it should work with any git installation.

Adding a remote works the same way

git remote add remotename file:///cygdrive/c/path/to/repository/

For completude, you can also easily do it without calling any heavy library function (no snprintf, no strcat, not even memcpy). It can be useful, say if you are programming some microcontroller or OS kernel where libc is not available.

Nothing really fancy you can find similar code around if you google for it. Really it's not much more complicated than calling snprintf and much faster.

#include <stdio.h>

int main(){
    unsigned char buf[] = {0, 1, 10, 11};
    /* target buffer should be large enough */
    char str[12];

    unsigned char * pin = buf;
    const char * hex = "0123456789ABCDEF";
    char * pout = str;
    int i = 0;
    for(; i < sizeof(buf)-1; ++i){
        *pout++ = hex[(*pin>>4)&0xF];
        *pout++ = hex[(*pin++)&0xF];
        *pout++ = ':';
    }
    *pout++ = hex[(*pin>>4)&0xF];
    *pout++ = hex[(*pin)&0xF];
    *pout = 0;

    printf("%s\n", str);
}

Here is another slightly shorter version. It merely avoid intermediate index variable i and duplicating laste case code (but the terminating character is written two times).

#include <stdio.h>
int main(){
    unsigned char buf[] = {0, 1, 10, 11};
    /* target buffer should be large enough */
    char str[12];

    unsigned char * pin = buf;
    const char * hex = "0123456789ABCDEF";
    char * pout = str;
    for(; pin < buf+sizeof(buf); pout+=3, pin++){
        pout[0] = hex[(*pin>>4) & 0xF];
        pout[1] = hex[ *pin     & 0xF];
        pout[2] = ':';
    }
    pout[-1] = 0;

    printf("%s\n", str);
}

Below is yet another version to answer to a comment saying I used a "trick" to know the size of the input buffer. Actually it's not a trick but a necessary input knowledge (you need to know the size of the data that you are converting). I made this clearer by extracting the conversion code to a separate function. I also added boundary check code for target buffer, which is not really necessary if we know what we are doing.

#include <stdio.h>

void tohex(unsigned char * in, size_t insz, char * out, size_t outsz)
{
    unsigned char * pin = in;
    const char * hex = "0123456789ABCDEF";
    char * pout = out;
    for(; pin < in+insz; pout +=3, pin++){
        pout[0] = hex[(*pin>>4) & 0xF];
        pout[1] = hex[ *pin     & 0xF];
        pout[2] = ':';
        if (pout + 3 - out > outsz){
            /* Better to truncate output string than overflow buffer */
            /* it would be still better to either return a status */
            /* or ensure the target buffer is large enough and it never happen */
            break;
        }
    }
    pout[-1] = 0;
}

int main(){
    enum {insz = 4, outsz = 3*insz};
    unsigned char buf[] = {0, 1, 10, 11};
    char str[outsz];
    tohex(buf, insz, str, outsz);
    printf("%s\n", str);
}

ES6 of the day here;

const json_getAllKeys = data => (
  data.reduce((keys, obj) => (
    keys.concat(Object.keys(obj).filter(key => (
      keys.indexOf(key) === -1))
    )
  ), [])
)

And yes it can be written in very long one line;

const json_getAllKeys = data => data.reduce((keys, obj) => keys.concat(Object.keys(obj).filter(key => keys.indexOf(key) === -1)), [])

EDIT: Returns all first order keys if the input is of type array of objects

Try npm install -g typescript@latest. You can also use npm update instead of install, without the latest modifier.

If you don't know which checkboxes your page has (ex: if you are creating them dynamically) you can simply put a hidden field with the same name and 0 value right above the checkbox.

<input type="hidden" name="foo" value="0" />
<input type="checkbox" name="foo" value="1">

This way you will get 1 or 0 based on whether the checkbox is selected or not.

1) If you are using (PHP 5 >= 5.3.6) you can use SplFileInfo::getExtension — Gets the file extension

Example code

<?php

$info = new SplFileInfo('test.png');
var_dump($info->getExtension());

$info = new SplFileInfo('test.tar.gz');
var_dump($info->getExtension());

?>

This will output

string(3) "png"
string(2) "gz"

2) Another way of getting the extension if you are using (PHP 4 >= 4.0.3, PHP 5) is pathinfo

Example code

<?php

$ext = pathinfo('test.png', PATHINFO_EXTENSION);
var_dump($ext);

$ext = pathinfo('test.tar.gz', PATHINFO_EXTENSION);
var_dump($ext);

?>

This will output

string(3) "png"
string(2) "gz"

// EDIT: removed a bracket

One more option, not exactly what you asked, but can be useful:

Go to Settings -> Editor -> File and code templates -> Includes tab (on the right). There is a template header for the new files, you can use the username here:

/**
 * @author myname
 */

For system username use:

/**
 * @author ${USER}
 */

When we get this error while running our java application, check if we have some class name or package names starting with ”java.”, if so change the package name. This is happening because your package name is colliding with java system file names.

enctype='multipart/form-data' means that no characters will be encoded. that is why this type is used while uploading files to server.
So multipart/form-data is used when a form requires binary data, like the contents of a file, to be uploaded

I have written a small routine which copies formula from a cell to clipboard which one can easily paste in Visual Basic Editor.

    Public Sub CopyExcelFormulaInVBAFormat()
        Dim strFormula As String
        Dim objDataObj As Object

        '\Check that single cell is selected!
       If Selection.Cells.Count > 1 Then
            MsgBox "Select single cell only!", vbCritical
            Exit Sub
        End If

        'Check if we are not on a blank cell!
       If Len(ActiveCell.Formula) = 0 Then
            MsgBox "No Formula To Copy!", vbCritical
            Exit Sub
        End If

        'Add quotes as required in VBE
       strFormula = Chr(34) & Replace(ActiveCell.Formula, Chr(34), Chr(34) & Chr(34)) & Chr(34)

        'This is ClsID of MSFORMS Data Object
       Set objDataObj = CreateObject("New:{1C3B4210-F441-11CE-B9EA-00AA006B1A69}")
        objDataObj.SetText strFormula, 1
        objDataObj.PutInClipboard
        MsgBox "VBA Format formula copied to Clipboard!", vbInformation

        Set objDataObj = Nothing

    End Sub

As Drew Taylor pointed out, branch deletion with -d only considers the current HEAD in determining if the branch is "fully merged". It will complain even if the branch is merged with some other branch. The error message could definitely be clearer in this regard... You can either checkout the merged branch before deleting, or just use git branch -D. The capital -D will override the check entirely.

select substring(your_field, CHARINDEX(';',your_field)+1 ,CHARINDEX('[',your_field)-CHARINDEX(';',your_field)-1) from your_table

Can't get the others to work. I believe you just want what is in between ';' and '[' in all cases regardless of how long the string in between is. After specifying the field in the substring function, the second argument is the starting location of what you will extract. That is, where the ';' is + 1 (fourth position - the c), because you don't want to include ';'. The next argument takes the location of the '[' (position 14) and subtracts the location of the spot after the ';' (fourth position - this is why I now subtract 1 in the query). This basically says substring(field,location I want substring to begin, how long I want substring to be). I've used this same function in other cases. If some of the fields don't have ';' and '[', you'll want to filter those out in the "where" clause, but that's a little different than the question. If your ';' was say... ';;;', you would use 3 instead of 1 in the example. Hope this helps!

Not sure if you're doing something similar to what I am doing, but Im generating a load of source java from an XSD using JAXB in a seperate component using Maven. Lets say this artifact is called "base-model"

I wanted to import this artifact containing the java source and run hibernate over all classes in my "base-model" artifact jar and not specify each explicitly. Im adding "base-model" as a dependency for my hibernate component but the trouble is the tag in persistence.xml only allows you to specify absolute paths.

The way I got round it is to copy my "base-model" jar dependency explictly to my target dir and also strip the version of it. So whereas if I build my "base-model" artifact it generate "base-model-1.0-SNAPSHOT.jar", the copy-resources step copies it as "base-model.jar".

So in your pom for the hibernate component:

            <!-- We want to copy across all our artifacts containing java code
        generated from our scheams. We copy them across and strip the version
        so that our persistence.xml can reference them directly in the tag
        <jar-file>target/dependency/${artifactId}.jar</jar-file> -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <version>2.5.1</version>
            <executions>

                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>

                <stripVersion>true</stripVersion>
            </configuration>        
        </plugin>

Then I call the hibernate plugin in the next phase "process-classes":

            <!-- Generate the schema DDL -->
        <plugin>
            <groupId>org.codehaus.mojo</groupId>

                <execution>

                    </goals>
                </execution>
            </executions>
            <configuration>
                <components>
                    <component>

                        <implementation>annotationconfiguration</implementation>
                        <outputDirectory>/src/main/java</outputDirectory>
                    </component>
                </components>
                <componentProperties>
                    <persistenceunit>mysql</persistenceunit>
                    <implementation>jpaconfiguration</implementation>
                    <create>true</create>
                    <export>false</export>
                    <drop>true</drop>
                    <outputfilename>mysql-schema.sql</outputfilename>
                </componentProperties>
            </configuration>
        </plugin>

and finally in my persistence.xml I can explicitly set the location of the jar thus:

<jar-file>target/dependency/base-model.jar</jar-file>

and add the property:

<property name="hibernate.archive.autodetection" value="class, hbm"/>

Necromancing.
It looks you have just as good a schema to work with as me... Here is how to do it correctly:

In this example, the table name is dbo.T_SYS_Language_Forms, and the column name is LANG_UID

-- First, chech if the table exists...
IF 0 < (
    SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE = 'BASE TABLE'
    AND TABLE_SCHEMA = 'dbo'
    AND TABLE_NAME = 'T_SYS_Language_Forms'
)
BEGIN
    -- Check for NULL values in the primary-key column
    IF 0 = (SELECT COUNT(*) FROM T_SYS_Language_Forms WHERE LANG_UID IS NULL)
    BEGIN
        ALTER TABLE T_SYS_Language_Forms ALTER COLUMN LANG_UID uniqueidentifier NOT NULL 

        -- No, don't drop, FK references might already exist...
        -- Drop PK if exists 
        -- ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT pk_constraint_name 
        --DECLARE @pkDropCommand nvarchar(1000) 
        --SET @pkDropCommand = N'ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT ' + QUOTENAME((SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
        --WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
        --AND TABLE_SCHEMA = 'dbo' 
        --AND TABLE_NAME = 'T_SYS_Language_Forms' 
        ----AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
        --))
        ---- PRINT @pkDropCommand 
        --EXECUTE(@pkDropCommand) 

        -- Instead do
        -- EXEC sp_rename 'dbo.T_SYS_Language_Forms.PK_T_SYS_Language_Forms1234565', 'PK_T_SYS_Language_Forms';


        -- Check if they keys are unique (it is very possible they might not be) 
        IF 1 >= (SELECT TOP 1 COUNT(*) AS cnt FROM T_SYS_Language_Forms GROUP BY LANG_UID ORDER BY cnt DESC)
        BEGIN

            -- If no Primary key for this table
            IF 0 =  
            (
                SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
                WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
                AND TABLE_SCHEMA = 'dbo' 
                AND TABLE_NAME = 'T_SYS_Language_Forms' 
                -- AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
            )
                ALTER TABLE T_SYS_Language_Forms ADD CONSTRAINT PK_T_SYS_Language_Forms PRIMARY KEY CLUSTERED (LANG_UID ASC)
            ;

            -- Adding foreign key
            IF 0 = (SELECT COUNT(*) FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS WHERE CONSTRAINT_NAME = 'FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms') 
                ALTER TABLE T_ZO_SYS_Language_Forms WITH NOCHECK ADD CONSTRAINT FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms FOREIGN KEY(ZOLANG_LANG_UID) REFERENCES T_SYS_Language_Forms(LANG_UID); 
        END -- End uniqueness check
        ELSE
            PRINT 'FSCK, this column has duplicate keys, and can thus not be changed to primary key...' 
    END -- End NULL check
    ELSE
        PRINT 'FSCK, need to figure out how to update NULL value(s)...' 
END 

The Path is the only thing you really have to worry about if you are really new to Java. You need to drag your image into the main project file, and it will show up at the very bottom of the list.

Then the file path is pretty straight forward. This code goes into the constructor for the class.

    img = Toolkit.getDefaultToolkit().createImage("/home/ben/workspace/CS2/Background.jpg");

CS2 is the name of my project, and everything before that is leading to the workspace.

Here is the method which is used in Commerce SagePay and in Commerce Paypoint Drupal modules which basically compares document.location.href with the old value by first loading its own iframe, then external one.

So basically the idea is to load the blank page as a placeholder with its own JS code and hidden form. Then parent JS code will submit that hidden form where its #action points to the external iframe. Once the redirect/submit happens, the JS code which still running on that page can track your document.location.href value changes.

Here is example JS used in iframe:

;(function($) {
  Drupal.behaviors.commercePayPointIFrame = {
    attach: function (context, settings) {
      if (top.location != location) {
        $('html').hide();
        top.location.href = document.location.href;
      }
    }
  }
})(jQuery);

And here is JS used in parent page:

;(function($) {
  /**
   * Automatically submit the hidden form that points to the iframe.
   */
  Drupal.behaviors.commercePayPoint = {
    attach: function (context, settings) {
      $('div.payment-redirect-form form', context).submit();
      $('div.payment-redirect-form #edit-submit', context).hide();
      $('div.payment-redirect-form .checkout-help', context).hide();
    }
  }
})(jQuery);

Then in temporary blank landing page you need to include the form which will redirect to the external page.

I wrote this simple helper function:

#include <locale> // tolower

string to_lower(string s) {        
    for(char &c : s)
        c = tolower(c);
    return s;
}

Usage:

string s = "TEST";
cout << to_lower("HELLO WORLD"); // output: "hello word"
cout << to_lower(s); // won't change the original variable.

Using unset

To remove an element at particular index, we can use unset and then do copy to another array. Only just unset is not required in this case. Because unset does not remove the element it just sets null string to the particular index in array.

declare -a arr=('aa' 'bb' 'cc' 'dd' 'ee')
unset 'arr[1]'
declare -a arr2=()
i=0
for element in "${arr[@]}"
do
    arr2[$i]=$element
    ((++i))
done
echo "${arr[@]}"
echo "1st val is ${arr[1]}, 2nd val is ${arr[2]}"
echo "${arr2[@]}"
echo "1st val is ${arr2[1]}, 2nd val is ${arr2[2]}"

Output is

aa cc dd ee
1st val is , 2nd val is cc
aa cc dd ee
1st val is cc, 2nd val is dd

Using :<idx>

We can remove some set of elements using :<idx> also. For example if we want to remove 1st element we can use :1 as mentioned below.

declare -a arr=('aa' 'bb' 'cc' 'dd' 'ee')
arr2=("${arr[@]:1}")
echo "${arr2[@]}"
echo "1st val is ${arr2[1]}, 2nd val is ${arr2[2]}"

Output is

bb cc dd ee
1st val is cc, 2nd val is dd

document.cookie = "cookie_name=cookie_value; max-age=31536000; path=/";

Will set the value for a year.

How about using regex?

String firstWord = filename.replaceAll("\\..*","")

This replaces everything from the first dot to the end with "" (ie it clears it, leaving you with what you want)

Here's a test:

System.out.println("abc.def.hij".replaceAll("\\..*", "");

Output:

abc

I have a suggestion to properly handle rejects in a novel approach, without having multiple try-catch blocks.

import to from './to';

async foo(id: string): Promise<A> {
    let err, result;
    [err, result] = await to(someAsyncPromise()); // notice the to() here
    if (err) {
        return 400;
    }
    return 200;
}

Where the to.ts function should be imported from:

export default function to(promise: Promise<any>): Promise<any> {
    return promise.then(data => {
        return [null, data];
    }).catch(err => [err]);
}

Credits go to Dima Grossman in the following link.

The way I fix this problem is:

1. create a link from adb file(drag 'adb' with holding alt then drop to any directory and select 'link here')
2. use #sudo cp adb /bin (copy link from 1 to /bin)

I've done this several times and it works 100%(tested on Ubuntu 12.04 32/64bit).

The public keyword is used only when declaring a class method.

Since you're declaring a simple function and not a class you need to remove public from your code.

There is no such function; the easiest way to do this is to use a dict comprehension:

my_dictionary = {k: f(v) for k, v in my_dictionary.items()}

In python 2.7, use the .iteritems() method instead of .items() to save memory. The dict comprehension syntax wasn't introduced until python 2.7.

Note that there is no such method on lists either; you'd have to use a list comprehension or the map() function.

As such, you could use the map() function for processing your dict as well:

my_dictionary = dict(map(lambda kv: (kv[0], f(kv[1])), my_dictionary.iteritems()))

but that's not that readable, really.

bool hasErrors =  ViewData.ModelState.Values.Any(x => x.Errors.Count > 1);

or iterate with

    foreach (ModelState state in ViewData.ModelState.Values.Where(x => x.Errors.Count > 0))
    {

    }

simply using Viewbag data as IEnumerable<> list

@{
 var getlist= ViewBag.Listdata as IEnumerable<myproject.models.listmodel>;

  foreach (var item in getlist){   //using foreach
<span>item .name</span>
}

}

//---------or just write name inside the getlist
<span>getlist[0].name</span>

If you're looking for a document-level key event handling, then binding it during componentDidMount is the best way (as shown by Brad Colthurst's codepen example):

class ActionPanel extends React.Component {
  constructor(props){
    super(props);
    this.escFunction = this.escFunction.bind(this);
  }
  escFunction(event){
    if(event.keyCode === 27) {
      //Do whatever when esc is pressed
    }
  }
  componentDidMount(){
    document.addEventListener("keydown", this.escFunction, false);
  }
  componentWillUnmount(){
    document.removeEventListener("keydown", this.escFunction, false);
  }
  render(){
    return (   
      <input/>
    )
  }
}

Note that you should make sure to remove the key event listener on unmount to prevent potential errors and memory leaks.

EDIT: If you are using hooks, you can use this useEffect structure to produce a similar effect:

const ActionPanel = (props) => {
  const escFunction = useCallback((event) => {
    if(event.keyCode === 27) {
      //Do whatever when esc is pressed
    }
  }, []);

  useEffect(() => {
    document.addEventListener("keydown", escFunction, false);

    return () => {
      document.removeEventListener("keydown", escFunction, false);
    };
  }, []);

  return (   
    <input />
  )
};

Just in case anybody else runs into a similar issue: I kept the fade, but just added data-dismiss="modal" to the save button. Works for me.

That watermark in the bottom right only appears on mouseover. There's no parameter to remove that, however if you stack a transparent div on top of the video and make it a higher z-index and the same size of the video, your mouseover will not trigger the watermark because your mouse will be hitting the div.

Of course the tradeoff for this is that you lose the ability to actually click on the video to pause it. But if you want to leave the ability to pause it, you could display the controls and have the top layer div cover up until the bottom 30 pixels or so, letting you click the controls.

Using relative instead of absolute file path solved the problem for me. I had the same issue and setting allow_url_fopen=on did not help. This means for instance :

use $file="folder/file.ext"; instead of $file="https://website.com/folder/file.ext"; in

$f=fopen($file,"r+");

openssl genrsa -out mykey.pem 1024

will actually produce a public - private key pair. The pair is stored in the generated mykey.pem file.

openssl rsa -in mykey.pem -pubout > mykey.pub

will extract the public key and print that out. Here is a link to a page that describes this better.

EDIT: Check the examples section here. To just output the public part of a private key:

openssl rsa -in key.pem -pubout -out pubkey.pem

To get a usable public key for SSH purposes, use ssh-keygen:

ssh-keygen -y -f key.pem > key.pub

Instead of Windows PowerShell, find the item in the Start Menu called SharePoint 2013 Management Shell:

In general, let() is a nicer syntax, and it saves you typing @name symbols all over the place. But, caveat emptor! I have found let() also introduces subtle bugs (or at least head scratching) because the variable doesn't really exist until you try to use it... Tell tale sign: if adding a puts after the let() to see that the variable is correct allows a spec to pass, but without the puts the spec fails -- you have found this subtlety.

I have also found that let() doesn't seem to cache in all circumstances! I wrote it up in my blog: http://technicaldebt.com/?p=1242

Maybe it is just me?

With other drivers, you can attempt to make a connection and if it fails, you know the mongo server's down. Mongoskin needs to actually make some call (like ping) because it connects lazily. For php, you can use the try-to-connect method. Make a script!

PHP:

$dbIsRunning = true
try {
  $m = new MongoClient('localhost:27017');
} catch($e) {
  $dbIsRunning = false
}

I have to dedupe a very big table with many columns and speed is important. Thus I use this method which works for any table:

delete T from 
(select Row_Number() Over(Partition By BINARY_CHECKSUM(*) order by %%physloc%% ) As RowNumber, * From MyTable) T
Where T.RowNumber > 1

It will also generate error when you pass large string in ajax call parameter.

so for that alway use type post in ajax will resolve your issue 100% and no need to set the length in web.config.

// var UserId= array of 1000 userids

$.ajax({ global: false, url: SitePath + "/User/getAussizzMembersData", "data": { UserIds: UserId}, "type": "POST", "dataType": "JSON" }}

As Nikolai has said you can use the gdb 'set' command to change the value of a variable.

You can also use the 'set' command to change memory locations. eg. Expanding on Nikolai's example:

(gdb) l
6       {
7           int i;
8           struct file *f, *ftmp;
9
(gdb) set variable i = 10
(gdb) p i
$1 = 10

(gdb) p &i
$2 = (int *) 0xbfbb0000
(gdb) set *((int *) 0xbfbb0000) = 20
(gdb) p i
$3 = 20

This should work for any valid pointer, and can be cast to any appropriate data type.

if you just want to close form1 from form2 without closing form2 as well in the process, as the title suggests, then you could pass a reference to form 1 along to form 2 when you create it and use that to close form 1

for example you could add a

public class Form2 : Form
{
    Form2(Form1 parentForm):base()
    {
        this.parentForm = parentForm;
    }

    Form1 parentForm;
    .....
}

field and constructor to Form2

if you want to first close form2 and then form1 as the text of the question suggests, I'd go with Justins answer of returning an appropriate result to form1 on upon closing form2

Or you might be looking at this question because you happened to make a silly typo like I did and have the =~ reversed to ~=

Form1 frmnew = new Form1();
frmnew.ShowDialog();

After much further research, i managed to find a solution.

google.maps.event.addListener(map, 'click', function(event) {
   placeMarker(event.latLng);
});

function placeMarker(location) {
    var marker = new google.maps.Marker({
        position: location, 
        map: map
    });
}

Here is a solution which is an improvement over this one.

public static bool HasSameElementsAs<T>(
        this IEnumerable<T> first, 
        IEnumerable<T> second, 
        IEqualityComparer<T> comparer = null)
    {
        var firstMap = first
            .GroupBy(x => x, comparer)
            .ToDictionary(x => x.Key, x => x.Count(), comparer);

        var secondMap = second
            .GroupBy(x => x, comparer)
            .ToDictionary(x => x.Key, x => x.Count(), comparer);

        if (firstMap.Keys.Count != secondMap.Keys.Count)
            return false;

        if (firstMap.Keys.Any(k1 => !secondMap.ContainsKey(k1)))
            return false;

        return firstMap.Keys.All(x => firstMap[x] == secondMap[x]);
    }

This probably isnt relevant here. But to eliminate these html entites from an entire document, you can do something like this: (Assume document = page and please forgive the sloppy code, but if you have ideas as to how to make it better, Im all ears - Im new to this).

import re
import HTMLParser

regexp = "&.+?;" 
list_of_html = re.findall(regexp, page) #finds all html entites in page
for e in list_of_html:
    h = HTMLParser.HTMLParser()
    unescaped = h.unescape(e) #finds the unescaped value of the html entity
    page = page.replace(e, unescaped) #replaces html entity with unescaped value

You actually can switch on enums, but you can't switch on Strings until Java 7. You might consider using polymorphic method dispatch with Java enums rather than an explicit switch. Note that enums are objects in Java, not just symbols for ints like they are in C/C++. You can have a method on an enum type, then instead of writing a switch, just call the method - one line of code: done!

enum MyEnum {
    SOME_ENUM_CONSTANT {
        @Override
        public void method() {
            System.out.println("first enum constant behavior!");
        }
    },
    ANOTHER_ENUM_CONSTANT {
        @Override
        public void method() {
            System.out.println("second enum constant behavior!");
        }
    }; // note the semi-colon after the final constant, not just a comma!
    public abstract void method(); // could also be in an interface that MyEnum implements
}

void aMethodSomewhere(final MyEnum e) {
    doSomeStuff();
    e.method(); // here is where the switch would be, now it's one line of code!
    doSomeOtherStuff();
}

Add the right lines this way and and the horizontal borders using HR or border-bottom or .col-right-line:after. Don't forget media queries to get rid of the lines on small devices.

.col-right-line:before {
  position: absolute;
  content: " ";
  top: 0;
  right: 0;
  height: 100%;
  width: 1px;
  background-color: @color-neutral;
}

One thing that you could do would be to modify the catalina.sh (Unix based) or the catalina.bat (windows based).

Within each of the scripts you can set certain variables which only processes created under the shell will inherit. So for catalina.sh, use the following line:

export JAVA_HOME="intented java home"

And for windows use

set JAVA_HOME="intented java home"

There is a slight difference between the top answers, namely SUM(case when kind = 1 then 1 else 0 end) and SUM(kind=1).

When all values in column kind happen to be NULL, the result of SUM(case when kind = 1 then 1 else 0 end) is 0, whereas the result of SUM(kind=1) is NULL.

An example (http://sqlfiddle.com/#!9/b23807/2):

Schema:

CREATE TABLE Table1
(`first_col` int, `second_col` int)
;

INSERT INTO Table1
    (`first_col`, `second_col`)
VALUES
       (1, NULL),
       (1, NULL),
       (NULL, NULL)
;

Query results:

SELECT SUM(first_col=1) FROM Table1;
-- Result: 2
SELECT SUM(first_col=2) FROM Table1;
-- Result: 0
SELECT SUM(second_col=1) FROM Table1;
-- Result: NULL
SELECT SUM(CASE WHEN second_col=1 THEN 1 ELSE 0 END) FROM Table1;
-- Result: 0

Another option is to repeat the rules in two prefix locations using an included file. Since prefix locations are position independent in the configuration, using them can save some confusion as you add other regex locations later on. Avoiding regex locations when you can will help your configuration scale smoothly.

server {
    location /first/location/ {
        include shared.conf;
    }
    location /second/location/ {
        include shared.conf;
    }
}

Here's a sample shared.conf:

default_type text/plain;
return 200 "http_user_agent:    $http_user_agent
remote_addr:    $remote_addr
remote_port:    $remote_port
scheme:     $scheme
nginx_version:  $nginx_version
";

VueJS can't pickup your changes to the state if you manipulate arrays like this.

As explained in Common Beginner Gotchas, you should use array methods like push, splice or whatever and never modify the indexes like this a[2] = 2 nor the .length property of an array.

CoffeeScript has no ternary operator. That's what the docs say.

You can still use a syntax like

a = true then 5 else 10

It's way much clearer.

I wasn't satisfied with any of the answers, so I made Yet Another Enum (YEA!).

This implementation:

• uses more up-to-date JS
• requires just the declaration of this one class to easily create enums
• has mapping by name (colors.RED), string (colors["RED"]), and index (colors[0]), but you only need to pass in the strings as an array
• binds equivalent toString() and valueOf() functions to each enum object (if this is somehow not desired, one can simply remove it - small overhead for JS though)
• has optional global naming/storage by name string
• freezes the enum object once created so that it can't be modified

Special thanks to Andre 'Fi''s answer for some inspiration.

The codes:

class Enums {
  static create({ name = undefined, items = [] }) {
    let newEnum = {};
    newEnum.length = items.length;
    newEnum.items = items;
    for (let itemIndex in items) {
      //Map by name.
      newEnum[items[itemIndex]] = parseInt(itemIndex, 10);
      //Map by index.
      newEnum[parseInt(itemIndex, 10)] = items[itemIndex];
    }
    newEnum.toString = Enums.enumToString.bind(newEnum);
    newEnum.valueOf = newEnum.toString;
    //Optional naming and global registration.
    if (name != undefined) {
      newEnum.name = name;
      Enums[name] = newEnum;
    }
    //Prevent modification of the enum object.
    Object.freeze(newEnum);
    return newEnum;
  }
  static enumToString() {
    return "Enum " +
      (this.name != undefined ? this.name + " " : "") +
      "[" + this.items.toString() + "]";
  }
}

Usage:

let colors = Enums.create({
  name: "COLORS",
  items: [ "RED", "GREEN", "BLUE", "PORPLE" ]
});

//Global access, if named.
Enums.COLORS;

colors.items; //Array(4) [ "RED", "GREEN", "BLUE", "PORPLE" ]
colors.length; //4

colors.RED; //0
colors.GREEN; //1
colors.BLUE; //2
colors.PORPLE; //3
colors[0]; //"RED"
colors[1]; //"GREEN"
colors[2]; //"BLUE"
colors[3]; //"PORPLE"

colors.toString(); //"Enum COLORS [RED,GREEN,BLUE,PORPLE]"

//Enum frozen, makes it a real enum.
colors.RED = 9001;
colors.RED; //0

A simple way to getting resource string from string into a TextView. Here resourceName is the name of resource

int resID = getResources().getIdentifier(resourceName, "string", getPackageName());
textview.setText(resID);

I would suggest to use a variable instead of a public field:

public class Variables
{
   private static string name = "";

   public static string Name
   { 
        get { return name; }
        set { name = value; }

   }
}

From another class, you call your variable like this:

public class Main
{
    public void DoSomething()
    {
         string var = Variables.Name;
    }
}

You can do

[5, 10].min

or

[4, 7].max

They come from the Enumerable module, so anything that includes Enumerable will have those methods available.

v2.4 introduces own Array#min and Array#max, which are way faster than Enumerable's methods because they skip calling #each.

@nicholasklick mentions another option, Enumerable#minmax, but this time returning an array of [min, max].

[4, 5, 7, 10].minmax
=> [4, 10]

There are two ways to go about doing this.

1. Create a state in the constructor that contains the text input. Attach an onChange event to the input box that updates state each time. Then onClick you could just alert the state object.

2. handleClick: function() { alert(this.refs.myInput.value); },

I have used this before and I think in order to make sure credential persist and in a best secure way is

1. you can write them to the app config file using the ConfigurationManager class
2. securing the password using the SecureString class
3. then encrypting it using tools in the Cryptography namespace.

Sounds like mssql jdbc is buffering the entire resultset for you. You can add a connect string parameter saying selectMode=cursor or responseBuffering=adaptive. If you are on version 2.0+ of the 2005 mssql jdbc driver then response buffering should default to adaptive.

You have MANIFEST.MF file inside your META-INF folder. You can define optional or external dependencies that you must have access to.

Example:

Consider you have deployed your app and your container(at run time) found out that your app requires a newer version of a library which is not inside lib folder, in that case if you have defined the optional newer version in MANIFEST.MF then your app will refer to dependency from there (and will not crash).

On 64-bit systems the x64 key is:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

Most programs are listed there. Look at the keys: DisplayName DisplayVersion

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

if a device has an SD card, you use:

Environment.getExternalStorageState() 

if you don't have an SD card, you use:

Environment.getDataDirectory()

if there is no SD card, you can create your own directory on the device locally.

    //if there is no SD card, create new directory objects to make directory on device
        if (Environment.getExternalStorageState() == null) {
                        //create new file directory object
            directory = new File(Environment.getDataDirectory()
                    + "/RobotiumTestLog/");
            photoDirectory = new File(Environment.getDataDirectory()
                    + "/Robotium-Screenshots/");
            /*
             * this checks to see if there are any previous test photo files
             * if there are any photos, they are deleted for the sake of
             * memory
             */
            if (photoDirectory.exists()) {
                File[] dirFiles = photoDirectory.listFiles();
                if (dirFiles.length != 0) {
                    for (int ii = 0; ii <= dirFiles.length; ii++) {
                        dirFiles[ii].delete();
                    }
                }
            }
            // if no directory exists, create new directory
            if (!directory.exists()) {
                directory.mkdir();
            }

            // if phone DOES have sd card
        } else if (Environment.getExternalStorageState() != null) {
            // search for directory on SD card
            directory = new File(Environment.getExternalStorageDirectory()

If you don't mind using gVim, you can launch a single instance, so that when a new file is opened with it it's automatically opened in a new tab in the currently running instance.

to do this you can write: gVim --remote-tab-silent file

You could always make an alias to this command so that you don't have to type so many words. For example I use linux and bash and in my ~/.bashrc file I have:

alias g='gvim --remote-tab-silent'

so instead of doing $ mate file I do: $ g file

The volume it's on is mounted noexec.

You can use selenium and the webdriver for Firefox.

import selenium.webdriver

    time.sleep(2)
    root=driver.find_element_by_tag_name('html')
    root.screenshot('whole page screenshot.png')

Use list comprehension.

Short circuiting the creation of iterable using a list for example :)

>>> 
>>> k = x.__iter__()
>>> k
<listiterator object at 0x100517490>
>>> l = [y for y in k]
>>> l
[1, 2, 3, 4]
>>> 
>>> z = Set([1,2])
>>> z.update(l)
>>> z
set([1, 2, 3, 4])
>>> 

[Edit: missed the set part of question]

Yes there is a difference!

The immediate effect of using innerHTML versus dangerouslySetInnerHTML is identical -- the DOM node will update with the injected HTML.

However, behind the scenes when you use dangerouslySetInnerHTML it lets React know that the HTML inside of that component is not something it cares about.

Because React uses a virtual DOM, when it goes to compare the diff against the actual DOM, it can straight up bypass checking the children of that node because it knows the HTML is coming from another source. So there's performance gains.

More importantly, if you simply use innerHTML, React has no way to know the DOM node has been modified. The next time the render function is called, React will overwrite the content that was manually injected with what it thinks the correct state of that DOM node should be.

Your solution to use componentDidUpdate to always ensure the content is in sync I believe would work but there might be a flash during each render.

You should put the input for the last name into the same div where you have the first name.

<div>
    <label for="username">First Name</label>
    <input id="user_first_name" name="user[first_name]" size="30" type="text" />
    <input id="user_last_name" name="user[last_name]" size="30" type="text" />
</div>

Then, in your CSS give your #user_first_name and #user_last_name height and float them both to the left. For example:

#user_first_name{
    max-width:100px; /*max-width for responsiveness*/
    float:left;
}

#user_lastname_name{
    max-width:100px;
    float:left;
}

The shortest solution that will work with any Java version:

        <properties>
            <additionalparam>-Xdoclint:none</additionalparam>
        </properties>
    </profile>
</profiles>

Just add that to your POM and you're good to go.

Session.Abandon() destroys the session and the Session_OnEnd event is triggered.

Session.Clear() just removes all values (content) from the Object. The session with the same key is still alive.

So, if you use Session.Abandon(), you lose that specific session and the user will get a new session key. You could use it for example when the user logs out.

Use Session.Clear(), if you want that the user remaining in the same session (if you don't want the user to relogin for example) and reset all the session specific data.

You can use "accept" attribute as a filter in the file select box. Using "accept" help you filter input files base on their "suffix" or their "meme type"

1.Filter based on suffix: Here "accept" attribute just allow to select files with .jpeg extension.

<input type="file" accept=".jpeg" />

2.Filter based on "file type" Here "accept" attribute just allow to select file with "image/jpeg" type.

<input type="file" accept="image/jpeg" />

Important: We can change or delete the extension of a file, without changing the meme type. For example it is possible to have a file without extension, but the type of this file can be "image/jpeg". So this file can not pass the accept=".jpeg" filter. but it can pass accept="image/jpeg".

3.We can use * to select all kind of a file type. For example below code allow to select all kind of images. for example "image/png" or "image/jpeg" or ... . All of them are allowed.

<input type="file" accept="image/*" /> 

4.We can use cama ( , ) as an "or operator" in select attribute. For example to allow all kind of images or pdf files we can use this code:

<input type="file" accept="image/* , application/pdf" />

Android 4.4 (KitKat) and higher devices have a shell utility for recording the Android device screen. Connect a device in developer/debug mode running KitKat with the adb utility over USB and then type the following:

adb shell screenrecord /sdcard/movie.mp4
(Press Ctrl-C to stop)
adb pull /sdcard/movie.mp4

Screen recording is limited to a maximum of 3 minutes.

Reference: https://developer.android.com/studio/command-line/adb.html#screenrecord

'.'.join() or ".".join().. So any string instance has the method join()

Quickest, easiest laziest way to solve the problem:

1. Right-click on the project icon in Solution Explorer and choose "Properties".
2. Go to the "Application" tab and choose an earlier .NET target framework.
3. Save changes.
4. Go to the "Application" tab and choose the initial .NET target framework.
5. Save changes => problem solved!

Here is a very good solution -> http://css-tricks.com/replace-the-image-in-an-img-with-css/

Pro(s) and Con(s):
(+) works with vector image that have relative width/height (a thing that RobAu's answer does not handle)
(+) is cross browser (works also for IE8+)
(+) it only uses CSS. So no need to modify the img src (or if you do not have access/do not want to change the already existing img src attribute).
(-) sorry, it does use the background css attribute :)

MusiGenesis' response is functionally the correct one with regard to your question as stated; the SQL Server is smart enough to realize that if you are using "Group By" and not using any aggregate functions, then what you actually mean is "Distinct" - and therefore it generates an execution plan as if you'd simply used "Distinct."

However, I think it's important to note Hank's response as well - cavalier treatment of "Group By" and "Distinct" could lead to some pernicious gotchas down the line if you're not careful. It's not entirely correct to say that this is "not a question about aggregates" because you're asking about the functional difference between two SQL query keywords, one of which is meant to be used with aggregates and one of which is not.

A hammer can work to drive in a screw sometimes, but if you've got a screwdriver handy, why bother?

(for the purposes of this analogy, Hammer : Screwdriver :: GroupBy : Distinct and screw => get list of unique values in a table column)

Nothing should be global, except for constants.

public class MyMainClass {
    public final static boolean DEBUGMODE=true;
}

Put this within your main class. In other .java files, use it through:

if(MyMainClass.DEBUGMODE) System.out.println("Some debugging info");

Make sure when you move your code off the cutting room floor and into release you remove or comment out this functionality.

If you have a workhorse method, like a randomizer, I suggest creating a "Toolbox" package! All coders should have one, then whenever you want to use it in a .java, just import it!

For example:

<EditText
android:id="@+id/myNumber"
android:digits="0123456789."
android:inputType="numberDecimal"
/>

Reason #1

I tend to use explicit interface implementation when I want to discourage "programming to an implementation" (Design Principles from Design Patterns).

For example, in an MVP-based web application:

public interface INavigator {
    void Redirect(string url);
}

public sealed class StandardNavigator : INavigator {
    void INavigator.Redirect(string url) {
        Response.Redirect(url);
    }
}

Now another class (such as a presenter) is less likely to depend on the StandardNavigator implementation and more likely to depend on the INavigator interface (since the implementation would need to be cast to an interface to make use of the Redirect method).

Reason #2

Another reason I might go with an explicit interface implementation would be to keep a class's "default" interface cleaner. For example, if I were developing an ASP.NET server control, I might want two interfaces:

1. The class's primary interface, which is used by web page developers; and
2. A "hidden" interface used by the presenter that I develop to handle the control's logic

A simple example follows. It's a combo box control that lists customers. In this example, the web page developer isn't interested in populating the list; instead, they just want to be able to select a customer by GUID or to obtain the selected customer's GUID. A presenter would populate the box on the first page load, and this presenter is encapsulated by the control.

public sealed class CustomerComboBox : ComboBox, ICustomerComboBox {
    private readonly CustomerComboBoxPresenter presenter;

    public CustomerComboBox() {
        presenter = new CustomerComboBoxPresenter(this);
    }

    protected override void OnLoad() {
        if (!Page.IsPostBack) presenter.HandleFirstLoad();
    }

    // Primary interface used by web page developers
    public Guid ClientId {
        get { return new Guid(SelectedItem.Value); }
        set { SelectedItem.Value = value.ToString(); }
    }

    // "Hidden" interface used by presenter
    IEnumerable<CustomerDto> ICustomerComboBox.DataSource { set; }
}

The presenter populates the data source, and the web page developer never needs to be aware of its existence.

But's It's Not a Silver Cannonball

I wouldn't recommend always employing explicit interface implementations. Those are just two examples where they might be helpful.

If treating strings as bytes is more your thing, you can use the following functions

function u_atob(ascii) {
    return Uint8Array.from(atob(ascii), c => c.charCodeAt(0));
}

function u_btoa(buffer) {
    var binary = [];
    var bytes = new Uint8Array(buffer);
    for (var i = 0, il = bytes.byteLength; i < il; i++) {
        binary.push(String.fromCharCode(bytes[i]));
    }
    return btoa(binary.join(''));
}


// example, it works also with astral plane characters such as ''
var encodedString = new TextEncoder().encode('?');
var base64String = u_btoa(encodedString);
console.log('?' === new TextDecoder().decode(u_atob(base64String)))

Since Python is a better glue language, it may be easier to call the MATLAB part of your program from Python instead of vice-versa.

Check out Mlabwrap.

The approach I would take is: when reading the chapters from the database, instead of a collection of chapters, use a collection of books. This will have your chapters organised into books and you'll be able to use information from both classes to present the information to the user (you can even present it in a hierarchical way easily when using this approach).

You can use below example of case when with multiple conditions.

SELECT
  id,stud_name,
  CASE
    WHEN marks <= 40 THEN 'Bad'
    WHEN (marks >= 40 AND
      marks <= 100) THEN 'good'
    ELSE 'best'
  END AS Grade

For me my gitignore file was ignoring my packages folder. The following gitignore line was causing the issue -

**/packages/*

Removed and it restored my packages folder. Hope this helps someone else.

When you use the -m option putty does not allocate a tty, it runs the command and quits. If you want to run an interactive script (such as a sql client), you need to tell it to allocate a tty with -t, see 3.8.3.12 -t and -T: control pseudo-terminal allocation. You'll avoid keeping a script on the server, as well as having to invoke it once you're connected.

Here's what I'm using to connect to mysql from a batch file:

#mysql.bat start putty -t -load "sessionname" -l username -pw password -m c:\mysql.sh

#mysql.sh mysql -h localhost -u username --password="foo" mydb

The rules to avoid collision of names are both in the C++ standard (see Stroustrup book) and mentioned by C++ gurus (Sutter, etc.).

Personal rule

Because I did not want to deal with cases, and wanted a simple rule, I have designed a personal one that is both simple and correct:

When naming a symbol, you will avoid collision with compiler/OS/standard libraries if you:

• never start a symbol with an underscore
• never name a symbol with two consecutive underscores inside.

Of course, putting your code in an unique namespace helps to avoid collision, too (but won't protect against evil macros)

Some examples

(I use macros because they are the more code-polluting of C/C++ symbols, but it could be anything from variable name to class name)

#define _WRONG
#define __WRONG_AGAIN
#define RIGHT_
#define WRONG__WRONG
#define RIGHT_RIGHT
#define RIGHT_x_RIGHT

Extracts from C++0x draft

From the n3242.pdf file (I expect the final standard text to be similar):

17.6.3.3.2 Global names [global.names]

Certain sets of names and function signatures are always reserved to the implementation:

— Each name that contains a double underscore _ _ or begins with an underscore followed by an uppercase letter (2.12) is reserved to the implementation for any use.

— Each name that begins with an underscore is reserved to the implementation for use as a name in the global namespace.

But also:

17.6.3.3.5 User-defined literal suffixes [usrlit.suffix]

Literal suffix identifiers that do not start with an underscore are reserved for future standardization.

This last clause is confusing, unless you consider that a name starting with one underscore and followed by a lowercase letter would be Ok if not defined in the global namespace...

In my case , I got this Error in Tensorflow , Reason was i was trying to feed a array with different length or sequences :

example :

import tensorflow as tf

input_x = tf.placeholder(tf.int32,[None,None])



word_embedding = tf.get_variable('embeddin',shape=[len(vocab_),110],dtype=tf.float32,initializer=tf.random_uniform_initializer(-0.01,0.01))

embedding_look=tf.nn.embedding_lookup(word_embedding,input_x)

with tf.Session() as tt:
    tt.run(tf.global_variables_initializer())

    a,b=tt.run([word_embedding,embedding_look],feed_dict={input_x:example_array})
    print(b)

And if my array is :

example_array = [[1,2,3],[1,2]]

Then i will get error :

ValueError: setting an array element with a sequence.

but if i do padding then :

example_array = [[1,2,3],[1,2,0]]

Now it's working.

strong is the default. An object remains “alive” as long as there is a strong pointer to it.

weak specifies a reference that does not keep the referenced object alive. A weak reference is set to nil when there are no strong references to the object.

Merge them in two steps, df1 and df2 first, and then the result of that to df3.

In [33]: s1 = pd.merge(df1, df2, how='left', on=['Year', 'Week', 'Colour'])

I dropped year from df3 since you don't need it for the last join.

In [39]: df = pd.merge(s1, df3[['Week', 'Colour', 'Val3']],
                       how='left', on=['Week', 'Colour'])

In [40]: df
Out[40]: 
   Year Week Colour  Val1  Val2 Val3
0  2014    A    Red    50   NaN  NaN
1  2014    B    Red    60   NaN   60
2  2014    B  Black    70   100   10
3  2014    C    Red    10    20  NaN
4  2014    D  Green    20   NaN   20

Python3.exe is not defined in windows

Specify the path for required version of python when you need to used it by creating virtual environment for your project

Python 3

virtualenv --python=C:\PATH_TO_PYTHON\python.exe environment

Python2

virtualenv --python=C:\PATH_TO_PYTHON\python.exe environment

then activate the environment using

.\environment\Scripts\activate.ps1

As to my understanding it help your content adjust with different values of font family and font sizes.Thus making your content scalable. As to the issue of inhering font size we can always override by giving a specific font size for the element.

You are asking a lot of questions that you could answer yourself by reading the documentation, so I'll give you a general advice: read it and experiment in the python shell. You'll see that itemgetter returns a callable:

>>> func = operator.itemgetter(1)
>>> func(a)
['Paul', 22, 'Car Dealer']
>>> func(a[0])
8

To do it in a different way, you can use lambda:

a.sort(key=lambda x: x[1])

And reverse it:

a.sort(key=operator.itemgetter(1), reverse=True)

Sort by more than one column:

a.sort(key=operator.itemgetter(1,2))

See the sorting How To.

In my case setting AppPool->AdvancedSettings->Maximum Worker Proccesses to 1 helped.

Just in case anybody want to find how in oracle and came here (like me), the syntax is

select length(FIELD) from TABLE

just in case ;)

See our SD Thicket PHP Obfuscator for an obfuscator that works just fine with arbitrarily large sets of pages. It operates primarily by scrambling identifier names. With modest to large applications, this can make the code extremely difficult to understand, which is the entire purpose.

It doesn't waste any energy on "eval(decode(encodedprogramcode))" schemes, which a lot of PHP "obfuscators" do [these are "encoder"s, not "obfuscator"s], because any clod can find that call and execute the eval-decode himself and get the decoded code.

It uses a language-precise parser to process the PHP; it will tell you if your program is syntactically invalid. More importantly, it knows the whole language precisely; it won't get lost or confused, and it won't break your code (other that what happens if you obfuscate "incorrectly", e.g., fail to identify the public API of the code correctly).

Yes, it obfuscates identifiers identically across pages; if it didn't do that, the result wouldn't work.

Editing Windows registries is not worth it and not safe, use Map network drive and load the network share as if it's loaded from one of your local drives.

You can try this:

function checkIfExistingValue(obj, key, value) {
    return obj.hasOwnProperty(key) && obj[key] === value;
}
var test = [{name : "jack", sex: F}, {name: "joe", sex: M}]
console.log(test.some(function(person) { return checkIfExistingValue(person, "name", "jack"); }));

you can use np.int_:

>>> x = np.array([[1.0, 2.3], [1.3, 2.9]])
>>> x
array([[ 1. ,  2.3],
       [ 1.3,  2.9]])
>>> np.int_(x)
array([[1, 2],
       [1, 2]])

this is for Boy:

select party_code 
from abc as a
where party_code not in (select party_code 
                         from xyz 
                         where party_code = a.party_code);

this works regardless of ansi settings

<button my-directive="push">Push to Go</button>

app.directive("myDirective", function() {
    return {
        restrict : "A",
         link: function(scope, elm, attrs) {
                elm.bind('click', function(event) {

                    alert("You pressed button: " + event.target.getAttribute('my-directive'));
                });
        }
    };
});

here is what I did

I'm using directive as html attribute and I passed parameter as following in my HTML file. my-directive="push" And from the directive I retrieved it from the Mouse-click event object. event.target.getAttribute('my-directive').

You can't force the String arrays to have a specific size. You can do this:

private List<String[]> addresses = new ArrayList<String[]>();

but an array of any size can be added to this list.

However, as others have mentioned, the correct thing to do here is to create a separate class representing addresses. Then you would have something like:

private List<Address> addresses = new ArrayList<Address>();

You can solve any equation including adding with this code:

@echo off

title Richie's Calculator 3.0

:main

echo Welcome to Richie's Calculator 3.0

echo Press any key to begin calculating...

pause>nul

echo Enter An Equation

echo Example: 1+1

set /p 

set /a sum=%equation%

echo.

echo The Answer Is:

echo %sum%

echo.

echo Press any key to return to the main menu

pause>nul

cls

goto main

if(TextUtils.isEmpty(firstName.getText().toString()){
      firstName.setError("TEXT ERROR HERE");
}

Or you can also use TextInputLayout which has some useful method and some user friendly animation

With git remote show origin you have to be in the projects directory. But if you want to determine the URLs from anywhere else you could use:

cat <path2project>/.git/config | grep url

If you'll need this command often, you could define an alias in your .bashrc or .bash_profile with MacOS.

alias giturl='cat ./.git/config | grep url'

So you just need to call giturl in the Git root folder in order to simply obtain its URL.

If you extend this alias like this

alias giturl='cat .git/config | grep -i url | cut -d'=' -f 2'

you get only the plain URL without the preceding

"url="

in

url=http://example.com/repo.git

you get more possibilities in its usage:

Example

On Mac you could call open $(giturl) to open the URL in the standard browser.

Or chrome $(giturl) to open it with the Chrome browser on Linux.

I think you can achieve this the quickest by using the where function:

For example looking for items greater than 0.2 in a numpy array and replacing those with 0:

import numpy as np

nums = np.random.rand(4,3)

print np.where(nums > 0.2, 0, nums)

.hover() function accepts two function arguments, one for mouseenter event and one for mouseleave event.

An additional tip if you want only the log shown in the past half hour with timestamps, or within another set time. Adjust date format to match your system. This one works on Ubuntu 16.04LTS:

adb shell logcat -d -v time -t "$(date '+%m-%d %H:%M:%S.%3N' -d '30 minutes ago')" > log_name.log

The new filtering feature in Servlet 2.4 basically alleviates the restriction that filters can only operate in the request flow before and after the actual request processing by the application server. Instead, Servlet 2.4 filters can now interact with the request dispatcher at every dispatch point. This means that when a Web resource forwards a request to another resource (for instance, a servlet forwarding the request to a JSP page in the same application), a filter can be operating before the request is handled by the targeted resource. It also means that should a Web resource include the output or function from other Web resources (for instance, a JSP page including the output from multiple other JSP pages), Servlet 2.4 filters can work before and after each of the included resources. .

To turn on that feature you need:

web.xml

<filter>   
    <filter-name>springSecurityFilterChain</filter-name>   
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> 
</filter>  
<filter-mapping>   
    <filter-name>springSecurityFilterChain</filter-name>   
    <url-pattern>/<strike>*</strike></url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
</filter-mapping>

return "forward:/login?j_username=" + registrationModel.getUserEmail()

• but i already assigned values such that irp.WrmVersion = "10.4";

J.Random Coder's answer and initialize version field.

private string version = "10.4';

I don't know whether it's rare or not, but I've certainly done the same thing.

As has been pointed out, the difficulty with making this part of the language itself is when a class makes use of multiple inheritance.
