Run:

pip  list

You should get a list of packages (including panda) and their versions, e.g.:

beautifulsoup4 (4.5.1)
cycler (0.10.0)
jdcal (1.3)
matplotlib (1.5.3)
numpy (1.11.1)
openpyxl (2.2.0b1)
pandas (0.18.1)
pip (8.1.2)
pyparsing (2.1.9)
python-dateutil (2.2)
python-nmap (0.6.1)
pytz (2016.6.1)
requests (2.11.1)
setuptools (20.10.1)
six (1.10.0)
SQLAlchemy (1.0.15)
xlrd (1.0.0)

First of all, you should be using json.loads, not json.dumps. loads converts JSON source text to a Python value, while dumps goes the other way.

After you fix that, based on the JSON snippet at the top of your question, readable_json will be a list, and so readable_json['firstName'] is meaningless. The correct way to get the 'firstName' field of every element of a list is to eliminate the playerstuff = readable_json['firstName'] line and change for i in playerstuff: to for i in readable_json:.

To read characters try

scan("/PathTo/file.csv", "")

If you're reading numeric values, then just use

scan("/PathTo/file.csv")

scan by default will use white space as separator. The type of the second arg defines 'what' to read (defaults to double()).

To determine if a String contains an upper case and a lower case char, you can use the following:

boolean hasUppercase = !password.equals(password.toLowerCase());
boolean hasLowercase = !password.equals(password.toUpperCase());

This allows you to check:

if(!hasUppercase)System.out.println("Must have an uppercase Character");
if(!hasLowercase)System.out.println("Must have a lowercase Character");

Essentially, this works by checking if the String is equal to its entirely lowercase, or uppercase equivalent. If this is not true, then there must be at least one character that is uppercase or lowercase.

As for your other conditions, these can be satisfied in a similar way:

boolean isAtLeast8   = password.length() >= 8;//Checks for at least 8 characters
boolean hasSpecial   = !password.matches("[A-Za-z0-9 ]*");//Checks at least one char is not alpha numeric
boolean noConditions = !(password.contains("AND") || password.contains("NOT"));//Check that it doesn't contain AND or NOT

With suitable error messages as above.

Just append a div with that class to body, then remove it when you're done:

// Show the backdrop
$('<div class="modal-backdrop"></div>').appendTo(document.body);

// Remove it (later)
$(".modal-backdrop").remove();

Live Example:

$("input").click(function() {_x000D_
  var bd = $('<div class="modal-backdrop"></div>');_x000D_
  bd.appendTo(document.body);_x000D_
  setTimeout(function() {_x000D_
    bd.remove();_x000D_
  }, 2000);_x000D_
});

I ended up using a combination of a structure of params and variadic args. This way, I didn't have to change the existing interface which was consumed by several services and my service was able to pass additional params as needed. Sample code in golang playground: https://play.golang.org/p/G668FA97Nu

You can access other containers' service by their name(ping apachewill get the ip or curl http://apache would access the http service) And this can be a alternative of a static ip.

The answer of Uttam didnt work for me. I just got null when I do:

Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata, 0, bitmapdata.length);

In my case, bitmapdata only has the buffer of the pixels, so it is imposible for the function decodeByteArray to guess which the width, the height and the color bits use. So I tried this and it worked:

//Create bitmap with width, height, and 4 bytes color (RGBA)    
Bitmap bmp = Bitmap.createBitmap(imageWidth, imageHeight, Bitmap.Config.ARGB_8888);
ByteBuffer buffer = ByteBuffer.wrap(bitmapdata);
bmp.copyPixelsFromBuffer(buffer);

Check https://developer.android.com/reference/android/graphics/Bitmap.Config.html for different color options

You can use:

try:
   # get your models
except ObjectDoesNotExist:
   # do something

Easy as

img {
  filter: brightness(50%);
}

php test.php

should do it, or

php -f test.php

to be explicit.

class Example extends React.Component {
  render() {
    return <h1>{this.props.text}</h1>;

}

Example.defaultProps = { text: 'yo' }; 

You can do it like that but storing a DataSet object in Session is not very efficient. If you have a web app with lots of users it will clog your server memory really fast.

If you really must do it like that I suggest removing it from the session as soon as you don't need the DataSet.

The main difference is w+ truncate the file to zero length if it exists or create a new file if it doesn't. While r+ neither deletes the content nor create a new file if it doesn't exist.

Try these codes and you will understand:

#include <stdio.h>
int main()
{
   FILE *fp;

   fp = fopen("test.txt", "w+");
   fprintf(fp, "This is testing for fprintf...\n");
   fputs("This is testing for fputs...\n", fp);
   fclose(fp);
}  

and then this

#include <stdio.h>
int main()
{
   FILE *fp;

   fp = fopen("test.txt", "w+");
   fclose(fp);
}   

Then open the file test.txt and see the what happens. You will see that all data written by the first program has been erased.
Repeat this for r+ and see the result. Hope you will understand.

We can define maximum pool size in following way:

                <pool> 
               <min-pool-size>5</min-pool-size>
                <max-pool-size>200</max-pool-size>
                <prefill>true</prefill>
                <use-strict-min>true</use-strict-min>
                <flush-strategy>IdleConnections</flush-strategy>
                </pool>

I solved it in my site making this in functions.php

add_action("template_redirect", "start_buffer");
add_action("shutdown", "end_buffer", 999);

function filter_buffer($buffer) {
    $buffer = replace_insecure_links($buffer);
    return $buffer;
}
function start_buffer(){
    ob_start("filter_buffer");
}

function end_buffer(){
    if (ob_get_length()) ob_end_flush();
}

function replace_insecure_links($str) {

   $str = str_replace ( array("http://www.yoursite.com/", "https://www.yoursite.com/") , array("/", "/"), $str);

   return apply_filters("rsssl_fixer_output", $str);

}

I took part of one plugin, cut it into pieces and make this. It replaced ALL links in my site (menus, css, scripts etc.) and everything was working.

Create docker image with openssh-server preinstalled:

Dockerfile

FROM ubuntu:16.04

RUN apt-get update && apt-get install -y openssh-server
RUN mkdir /var/run/sshd
RUN echo 'root:screencast' | chpasswd
RUN sed -i 's/PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config

# SSH login fix. Otherwise user is kicked off after login
RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd

ENV NOTVISIBLE "in users profile"
RUN echo "export VISIBLE=now" >> /etc/profile

EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]

Build the image using:

$ docker build -t eg_sshd .

Run a test_sshd container:

$ docker run -d -P --name test_sshd eg_sshd
$ docker port test_sshd 22

Maybe you can use jQuery selectbox replacement. It's a jQuery plugin.

double click the button and add write // this.close();

  private void buttonClick(object sender, EventArgs e)
{
    this.Close();
}

Seeing the number of views on this question, and the lack of answers that cover both blinking and stopping it, here goes: try jQuery.blinker out (demo).

HTML:

<p>Hello there!</p>

JavaScript:

var p = $("p");

p.blinker();

p.bind({
    // pause blinking on mouseenter
    mouseenter: function(){
        $(this).data("blinker").pause();
    },
    // resume blinking on mouseleave
    mouseleave: function(){
        $(this).data("blinker").blinkagain();
    }
});

UPDATE

You can use Map object introduced in ES6. Basically instead of finding parents by iterating over the array again, you'll just get the parent item from the array by parent's id like you get items in an array by index.

Here is the simple example:

const people = [
  {
    id: "12",
    parentId: "0",
    text: "Man",
    level: "1",
    children: null
  },
  {
    id: "6",
    parentId: "12",
    text: "Boy",
    level: "2",
    children: null
  },
  {
    id: "7",
    parentId: "12",
    text: "Other",
    level: "2",
    children: null
  },
  {
    id: "9",
    parentId: "0",
    text: "Woman",
    level: "1",
    children: null
  },
  {
    id: "11",
    parentId: "9",
    text: "Girl",
    level: "2",
    children: null
  }
];

function toTree(arr) {
  let arrMap = new Map(arr.map(item => [item.id, item]));
  let tree = [];

  for (let i = 0; i < arr.length; i++) {
    let item = arr[i];

    if (item.parentId !== "0") {
      let parentItem = arrMap.get(item.parentId);

      if (parentItem) {
        let { children } = parentItem;

        if (children) {
          parentItem.children.push(item);
        } else {
          parentItem.children = [item];
        }
      }
    } else {
      tree.push(item);
    }
  }

  return tree;
}

let tree = toTree(people);

console.log(tree);

This worked for me. But it didn't list in alphabetical order.

find "$(pwd)" -maxdepth 1

This command lists alphabetically as well as lists hidden files too.

ls -d -1 "$PWD/".*; ls -d -1 "$PWD/"*;

If you don't want to download an archive you can use GitHub Pages to render this.

1. Fork the repository to your account.
2. Clone it locally on your machine
3. Create a gh-pages branch (if one already exists, remove it and create a new one based off master).
4. Push the branch back to GitHub.
5. View the pages at http://username.github.io/repo`

In code:

git clone [email protected]:username/repo.git
cd repo
git branch gh-pages
# Might need to do this first: git branch -D gh-pages
git push -u origin gh-pages # Push the new branch back to github
Go to http://username.github.io/repo

If you're using the new Docker for Mac (or Docker for Windows), just right-click the Docker tray icon and select Preferences (Windows: Settings), then go to Advanced, and under Proxies specify your proxy settings there. Click Apply and Restart and wait until Docker restarts.

If you only have php code in one html file but have multiple other files that only contain html code, you can add the following to your .htaccess file so it will only serve that particular file as php.

<Files yourpage.html>
AddType application/x-httpd-php .html 
//you may need to use x-httpd-php5 if you are using php 5 or higher
</Files>

This will make the PHP executable ONLY on the "yourpage.html" file and not on all of your html pages which will prevent slowdown on your entire server.

As to why someone might want to serve php via an html file, I use the IMPORTHTML function in google spreadsheets to import JSON data from an external url that must be parsed with php to clean it up and build an html table. So far I haven't found any way to import a .php file into google spreadsheets so it must be saved as an .html file for the function to work. Being able to serve php via an .html file is necessary for that particular use.

What worked for me, was just dropping the table, even though it didnt exist. Then I re created the table and repopulated from an sql dump done previously.

There must be some metabase of table names, and it was most likely still existing in there till i dropped it.

2019 Update

There are various ways to handle this more elegantly now. Please see some other answers on this thread. Tech moves fast so answers can often become out of date fairly quickly. My answer will still work but it's worth looking at alternatives as well.

2012 Answer

Using your code, the issue is that you haven't waited for a socket to be assigned to the request before attempting to set stuff on the socket object. It's all async so:

var options = { ... }
var req = http.request(options, function(res) {
  // Usual stuff: on(data), on(end), chunks, etc...
});

req.on('socket', function (socket) {
    socket.setTimeout(myTimeout);  
    socket.on('timeout', function() {
        req.abort();
    });
});

req.on('error', function(err) {
    if (err.code === "ECONNRESET") {
        console.log("Timeout occurs");
        //specific error treatment
    }
    //other error treatment
});

req.write('something');
req.end();

The 'socket' event is fired when the request is assigned a socket object.

@AnsgarWiechers - it's not my experience that querying everything and then pruning the result is more efficient when you're doing a targeted search of known accounts. Although, yes, it is also more efficient to select just the properties you need to return.

The below examples are based on a domain in the range of 20,000 account objects.

measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st }
...
Seconds           : 16
Milliseconds      : 208

measure-command {$userlist | get-aduser -Properties DisplayName,st}
...
Seconds           : 3
Milliseconds      : 496

In the second example, $userlist contains 368 account names (just strings, not pre-fetched account objects).

Note that if I include the where clause per your suggestion to prune to the actually desired results, it's even more expensive.

measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st |where {$userlist -Contains $_.samaccountname } }
...
Seconds           : 17
Milliseconds      : 876

Indexed attributes seem to have similar performance (I tried just returning displayName).

Even if I return all user account properties in my set, it's more efficient. (Adding a select statement to the below brings it down by a half-second).

measure-command {$userlist | get-aduser -Properties *}
...
Seconds           : 12
Milliseconds      : 75

I can't find a good document that was written in ye olde days about AD queries to link to, but you're hitting every account in your search scope to return the properties. This discusses the basics of doing effective AD queries - scoping and filtering: https://msdn.microsoft.com/en-us/library/ms808539.aspx#efficientadapps_topic01

When your search scope is "*", you're still building a (big) list of the objects and iterating through each one. An LDAP search filter is always more efficient to build the list first (or a narrow search base, which is again building a smaller list to query).

Here an idea to simplify the syntax:

public class IgnoreCase
{
    private readonly string _value;

    public IgnoreCase(string s)
    {
        _value = s;
    }

    protected bool Equals(IgnoreCase other)
    {
        return this == other;
    }

    public override bool Equals(object obj)
    {
        return obj != null &&
               (ReferenceEquals(this, obj) || (obj.GetType() == GetType() && this == (IgnoreCase) obj));
    }

    public override int GetHashCode()
    {
        return _value?.GetHashCode() ?? 0;
    }

    public static bool operator ==(IgnoreCase a, IgnoreCase b)
    {
        return string.Equals(a, b, StringComparison.OrdinalIgnoreCase);
    }

    public static bool operator !=(IgnoreCase a, IgnoreCase b)
    {
        return !(a == b);
    }

    public static implicit operator string(IgnoreCase s)
    {
        return s._value;
    }

    public static implicit operator IgnoreCase(string s)
    {
        return new IgnoreCase(s);
    }
}

Usable like:

Console.WriteLine((IgnoreCase) "a" == "b"); // false
Console.WriteLine((IgnoreCase) "abc" == "abC"); // true
Console.WriteLine((IgnoreCase) "Abc" == "aBc"); // true
Console.WriteLine((IgnoreCase) "ABC" == "ABC"); // true

Read the spec for the attributes and for CSS.

• id must be unique. class does not have to be
• id has higher (highest!) specificity in CSS
• Elements can have multiple non-ordinal classes (separated by spaces), but only one id
• It is faster to select an element by it's ID when querying the DOM
• id can be used as an anchor target (using the fragment of the request) for any element. name only works with anchors (<a>)

This solution avoids using rules:

BEGIN
   INSERT INTO tableA (unique_column,c2,c3) VALUES (1,2,3);
EXCEPTION 
   WHEN unique_violation THEN
     UPDATE tableA SET c2 = 2, c3 = 3 WHERE unique_column = 1;
END;

but it has a performance drawback (see PostgreSQL.org):

A block containing an EXCEPTION clause is significantly more expensive to enter and exit than a block without one. Therefore, don't use EXCEPTION without need.

Here is an excellent header only class template to measure the elapsed time of a function or any code block:

#ifndef EXECUTION_TIMER_H
#define EXECUTION_TIMER_H

template<class Resolution = std::chrono::milliseconds>
class ExecutionTimer {
public:
    using Clock = std::conditional_t<std::chrono::high_resolution_clock::is_steady,
                                     std::chrono::high_resolution_clock,
                                     std::chrono::steady_clock>;
private:
    const Clock::time_point mStart = Clock::now();

public:
    ExecutionTimer() = default;
    ~ExecutionTimer() {
        const auto end = Clock::now();
        std::ostringstream strStream;
        strStream << "Destructor Elapsed: "
                  << std::chrono::duration_cast<Resolution>( end - mStart ).count()
                  << std::endl;
        std::cout << strStream.str() << std::endl;
    }    

    inline void stop() {
        const auto end = Clock::now();
        std::ostringstream strStream;
        strStream << "Stop Elapsed: "
                  << std::chrono::duration_cast<Resolution>(end - mStart).count()
                  << std::endl;
        std::cout << strStream.str() << std::endl;
    }

}; // ExecutionTimer

#endif // EXECUTION_TIMER_H

Here are some uses of it:

int main() {
    { // empty scope to display ExecutionTimer's destructor's message
         // displayed in milliseconds
         ExecutionTimer<std::chrono::milliseconds> timer;

         // function or code block here

         timer.stop();

    } 

    { // same as above
        ExecutionTimer<std::chrono::microseconds> timer;

        // code block here...

        timer.stop();
    }

    {  // same as above
       ExecutionTimer<std::chrono::nanoseconds> timer;

       // code block here...

       timer.stop();

    }

    {  // same as above
       ExecutionTimer<std::chrono::seconds> timer;

       // code block here...

       timer.stop();

    }              

    return 0;

Since the class is a template we can specify real easily in how we want our time to be measured & displayed. This is a very handy utility class template for doing bench marking and is very easy to use.

I recently needed to spawn processes for unit testing. This post was useful as I created a simple class to do that with either code as a string or code from my project. To build this class, you'll need the ICSharpCode.Decompiler and Microsoft.CodeAnalysis NuGet packages. Here's the class:

using ICSharpCode.Decompiler;
using ICSharpCode.Decompiler.CSharp;
using ICSharpCode.Decompiler.TypeSystem;
using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Reflection;

public static class CSharpRunner
{
   public static object Run(string snippet, IEnumerable<Assembly> references, string typeName, string methodName, params object[] args) =>
      Invoke(Compile(Parse(snippet), references), typeName, methodName, args);

   public static object Run(MethodInfo methodInfo, params object[] args)
   {
      var refs = methodInfo.DeclaringType.Assembly.GetReferencedAssemblies().Select(n => Assembly.Load(n));
      return Invoke(Compile(Decompile(methodInfo), refs), methodInfo.DeclaringType.FullName, methodInfo.Name, args);
   }

   private static Assembly Compile(SyntaxTree syntaxTree, IEnumerable<Assembly> references = null)
   {
      if (references is null) references = new[] { typeof(object).Assembly, typeof(Enumerable).Assembly };
      var mrefs = references.Select(a => MetadataReference.CreateFromFile(a.Location));
      var compilation = CSharpCompilation.Create(Path.GetRandomFileName(), new[] { syntaxTree }, mrefs, new CSharpCompilationOptions(OutputKind.DynamicallyLinkedLibrary));

      using (var ms = new MemoryStream())
      {
         var result = compilation.Emit(ms);
         if (result.Success)
         {
            ms.Seek(0, SeekOrigin.Begin);
            return Assembly.Load(ms.ToArray());
         }
         else
         {
            throw new InvalidOperationException(string.Join("\n", result.Diagnostics.Where(diagnostic => diagnostic.IsWarningAsError || diagnostic.Severity == DiagnosticSeverity.Error).Select(d => $"{d.Id}: {d.GetMessage()}")));
         }
      }
   }

   private static SyntaxTree Decompile(MethodInfo methodInfo)
   {
      var decompiler = new CSharpDecompiler(methodInfo.DeclaringType.Assembly.Location, new DecompilerSettings());
      var typeInfo = decompiler.TypeSystem.MainModule.Compilation.FindType(methodInfo.DeclaringType).GetDefinition();
      return Parse(decompiler.DecompileTypeAsString(typeInfo.FullTypeName));
   }

   private static object Invoke(Assembly assembly, string typeName, string methodName, object[] args)
   {
      var type = assembly.GetType(typeName);
      var obj = Activator.CreateInstance(type);
      return type.InvokeMember(methodName, BindingFlags.Default | BindingFlags.InvokeMethod, null, obj, args);
   }

   private static SyntaxTree Parse(string snippet) => CSharpSyntaxTree.ParseText(snippet);
}

To use it, call the Run methods as below:

void Demo1()
{
   const string code = @"
   public class Runner
   {
      public void Run() { System.IO.File.AppendAllText(@""C:\Temp\NUnitTest.txt"", System.DateTime.Now.ToString(""o"") + ""\n""); }
   }";

   CSharpRunner.Run(code, null, "Runner", "Run");
}

void Demo2()
{
   CSharpRunner.Run(typeof(Runner).GetMethod("Run"));
}

public class Runner
{
   public void Run() { System.IO.File.AppendAllText(@"C:\Temp\NUnitTest.txt", System.DateTime.Now.ToString("o") + "\n"); }
}

There's also a DailyRollingFileAppender

Edit: after reading this worrying statement:

DailyRollingFileAppender has been observed to exhibit synchronization issues and data loss. The log4j extras companion includes alternatives which should be considered for new deployments and which are discussed in the documentation for org.apache.log4j.rolling.RollingFileAppender.

from the above URL (which I never realized before), then the log4j-extras looks to be a better option.

LibreOffice provides a Workbook Compare feature: Edit -> Compare Document

One more solution is to use contains which will return true or false

_.contains($(".right-tree").css("background-image"), "stage1")

Hope this helps

You go into ~/.janus and run:

git submodule add <git@github ...> snipmate-snippets/snippets/

If you need more information about submodules (or git in general) ProGit is pretty useful.

Just remove the comma like this:

<article class="column wrapper"> 

I have answered this question here: https://stackoverflow.com/a/38238785/1773972

Basically use

StringUtils.substringBetween(str, "<%=", "%>");

This requirs using "Apache commons lang" library: https://mvnrepository.com/artifact/org.apache.commons/commons-lang3/3.4

This library has a lot of useful methods for working with string, you will really benefit from exploring this library in other areas of your java code !!!

import java.net.DatagramSocket;
import java.net.InetAddress;

try(final DatagramSocket socket = new DatagramSocket()){
  socket.connect(InetAddress.getByName("8.8.8.8"), 10002);
  ip = socket.getLocalAddress().getHostAddress();
}

This way works well when there are multiple network interfaces. It always returns the preferred outbound IP. The destination 8.8.8.8 is not needed to be reachable.

Connect on a UDP socket has the following effect: it sets the destination for Send/Recv, discards all packets from other addresses, and - which is what we use - transfers the socket into "connected" state, settings its appropriate fields. This includes checking the existence of the route to the destination according to the system's routing table and setting the local endpoint accordingly. The last part seems to be undocumented officially but it looks like an integral trait of Berkeley sockets API (a side effect of UDP "connected" state) that works reliably in both Windows and Linux across versions and distributions.

So, this method will give the local address that would be used to connect to the specified remote host. There is no real connection established, hence the specified remote ip can be unreachable.

Edit:

As @macomgil says, for MacOS you can do this:

Socket socket = new Socket();
socket.connect(new InetSocketAddress("google.com", 80));
System.out.println(socket.getLocalAddress());

A function I have in an install script made for exactly this

function assertInstalled() {
    for var in "$@"; do
        if ! which $var &> /dev/null; then
            echo "Install $var!"
            exit 1
        fi
    done
}

example call:

assertInstalled zsh vim wget python pip git cmake fc-cache

I also was facing the same issue ,this might be the simplest possible solution

source anaconda/bin/activate

for anaconda2 use

source anaconda2/bin/activate

depending on the name of the directory , then execute your command i.e. conda --create

You have to use the jquery attribute selector. You can read more here:

http://api.jquery.com/attribute-equals-selector/

In your case it should be:

$('input[name="btnName"]')

The following should work

$ad->getcodes()->distinct()->count('pid');

There are a few other choices in case the Adobe ActiveX isn't what you're looking for (since Acrobat must be present on the user machine and you can't ship it yourself).

For creating the PDF preview, first have a look at some other discussions on the subject on StackOverflow:

• How can I take preview of documents?
• Get a preview jpeg of a pdf on windows?
• .NET open PDF in winform without external dependencies
• PDF Previewing and viewing

In the last two I talk about a few things you can try:

• You can get a commercial renderer (PDFViewForNet, PDFRasterizer.NET, ABCPDF, ActivePDF, XpdfRasterizer and others in the other answers...).
  Most are fairly expensive though, especially if all you care about is making a simple preview/thumbnails.

• In addition to Omar Shahine's code snippet, there is a CodeProject article that shows how to use the Adobe ActiveX, but it may be out of date, easily broken by new releases and its legality is murky (basically it's ok for internal use but you can't ship it and you can't use it on a server to produce images of PDF).

• You could have a look at the source code for SumatraPDF, an OpenSource PDF viewer for windows.

• There is also Poppler, a rendering engine that uses Xpdf as a rendering engine. All of these are great but they will require a fair amount of commitment to make make them work and interface with .Net and they tend to be be distributed under the GPL.

• You may want to consider using GhostScript as an interpreter because rendering pages is a fairly simple process.
  The drawback is that you will need to either re-package it to install it with your app, or make it a pre-requisite (or at least a part of your install process).
  It's not a big challenge, and it's certainly easier than having to massage the other rendering engines into cooperating with .Net.
  I did a small project that you will find on the Developer Express forums as an attachment.
  Be careful of the license requirements for GhostScript through.
  If you can't leave with that then commercial software is probably your only choice.

It is better to process HTML as a template than to build nodes via JavaScript (HTML is not XML after all.) You can keep your IFRAME's HTML syntax clean by using a template and then appending the template's contents into another DIV.

<div id="placeholder"></div>

<script id="iframeTemplate" type="text/html">
    <iframe src="...">
        <!-- replace this line with alternate content -->
    </iframe>
</script>

<script type="text/javascript">
var element,
    html,
    template;

element = document.getElementById("placeholder");
template = document.getElementById("iframeTemplate");
html = template.innerHTML;

element.innerHTML = html;
</script>

try

sudo chown mysql:mysql -R /var/lib/mysql

then start your mysql service

systemctl start mysqld

I'm not sure if this is what you wanted, but this is a very hackish way to include php. What you do is you put the php you want to run in another file, and then you include that file in an image. For example:

RunFromHTML.php

<?php
  $file = fopen("file.txt", "w");
  //This will create a file called file.txt,
  //provided that it has write access to your filesystem
  fwrite($file, "Hello World!");
  //This will write "Hello World!" into file.txt
  fclose($file);
  //Always remember to close your files!
?>

RunPhp.html

<html>
  <!--head should be here, but isn't for demonstration's sake-->
  <body>
    <img style="display: none;" src="RunFromHTML.php">
    <!--This will run RunFromHTML.php-->
  </body>
</html>

Now, after visiting RunPhp.html, you should find a file called file.txt in the same directory that you created the above two files, and the file should contain "Hello World!" inside of it.

create a divider class as follows:

.divider{
    width:5px;
    height:auto;
    display:inline-block;
}

Then attach this to a div between the two buttons

<div style="text-align: center"> 
    <asp:Button ID="btnSubmit" runat="server" Text="Submit" Width="89px" OnClick="btnSubmit_Click" />
    <div class="divider"/>
    <asp:Button ID="btnClear" runat="server" Text="Clear" Width="89px" OnClick="btnClear_Click" />
</div>

This is the best way as it avoids the box model, which can be a pain on older browsers, and doesn't add any extra characters that would be picked up by a screen reader, so it is better for readability.

It's good to have a number of these types of divs for certain scenarios (my most used one is vert5spacer, similar to this but puts a block div with height 5 and width auto for spacing out items in a form etc.

If someone want to run it in PowerShell it works like below,

Run Powershell as Administrator

Then

setx /M PATH "$Env:PATH;<path to add>"

To verify, open another Powershell and view PATH as below,

$Env:PATH

It’s not easy to display live video stream from an IP camera on a web page because you need wide internet bandwidth and a great video player that is compatible with the major browsers.

But fortunately there are some cloud based services that can do this job for us. One of the best is IPCamLive. This service can receive RTSP/H264 video stream from an IP Camera and can broadcast it to the viewers. IPCamLive has Flash/HTML5 video player component that will display the video on PC, MAC, tablet or mobile. The greatest thing is that this site generates the needed HTML snippet for embedding the live video like this:

<iframe src="http://ipcamlive.com/player/player.php?alias=szekesfehervar" width="800px" height="600px"/>

So we just need to copy paste it into our HTML file without any modification.

I tried to get this working using FINDSTR, but for some reason my "debugging" command always output an error level of 0:

ECHO %ERRORLEVEL%

My workaround is to use Grep from Cygwin, which outputs the right errorlevel (it will give an errorlevel greater than 0) if a string is not found:

dir c:\*.tib >out 2>>&1
grep "1 File(s)" out
IF %ERRORLEVEL% NEQ 0 "Run other commands" ELSE "Run Errorlevel 0 commands"

Cygwin's grep will also output errorlevel 2 if the file is not found. Here's the hash from my version:

C:\temp\temp>grep --version grep (GNU grep) 2.4.2

C:\cygwin64\bin>md5sum grep.exe c0a50e9c731955628ab66235d10cea23 *grep.exe

C:\cygwin64\bin>sha1sum grep.exe ff43a335bbec71cfe99ce8d5cb4e7c1ecdb3db5c *grep.exe

pip has a --no-dependencies switch. You should use that.

For more information, run pip install -h, where you'll see this line:

--no-deps, --no-dependencies
                        Ignore package dependencies

You can simply Create a logout button and add this link to it and it will utimately log you out from the app and will redirect to your desired site:

https://appengine.google.com/_ah/logout?continue=http://www.YOURSITE.com

just toggle YOURSITE with your website

If you use has_many through, and want to alias:

has_many :alias_name, through: model_name, source: initial_name

you can't make easisly a slideup slidedown with css3 tha's why I've turned JensT script into a plugin with javascript fallback and callback.

in this way if you have a modern brwowser you can use the css3 csstransition. if your browser does not support it gracefuly use the old fashioned slideUp slideDown.

 /* css */
.csstransitions .mosneslide {
  -webkit-transition: height .4s ease-in-out;
  -moz-transition: height .4s ease-in-out;
  -ms-transition: height .4s ease-in-out;
  -o-transition: height .4s ease-in-out;
  transition: height .4s ease-in-out;
  max-height: 9999px;
  overflow: hidden;
  height: 0;
}

the plugin

(function ($) {
$.fn.mosne_slide = function (
    options) {
    // set default option values
    defaults = {
        delay: 750,
        before: function () {}, // before  callback
        after: function () {} // after callback;
    }
    // Extend default settings
    var settings = $.extend({},
        defaults, options);
    return this.each(function () {
        var $this = $(this);
        //on after
        settings.before.apply(
            $this);
        var height = $this.height();
        var width = $this.width();
        if (Modernizr.csstransitions) {
            // modern browsers
            if (height > 0) {

        }, settings.delay);
    });

})(jQuery);;

how to use it

/* jQuery */
$(".mosneslide").mosne_slide({
    delay:400,
    before:function(){console.log("start");},
    after:function(){console.log("done");}
});

you can find a demo page here http://www.mosne.it/playground/mosne_slide_up_down/

Use an onsubmit attribute on the form tag rather than onclick on the submit.

Here is a cross platform solution to clearing docker container logs:

docker run --rm -v /var/lib/docker:/var/lib/docker alpine sh -c "echo '' > $(docker inspect --format='{{.LogPath}}' CONTAINER_NAME)"

Paste this into your terminal and change CONTAINER_NAME to desired container name or id.

All of above can be avoided by simply declaring a friend value for runtime on the starting form.

Public Class Form1 
Friend sharevalue as string = "Boo"

Then access this variable from all forms simply using Form1.sharevalue

@XmlRootElement is not needed for unmarshalling - if one uses the 2 parameter form of Unmarshaller#unmarshall.

So, if instead of doing:

UserType user = (UserType) unmarshaller.unmarshal(new StringReader(responseString));

one should do:

JAXBElement<UserType> userElement = unmarshaller.unmarshal(someSource, UserType.class);
UserType user = userElement.getValue();

The latter code will not require @XmlRootElement annotation at UserType class level.

pathinfo()

$path_info = pathinfo('/foo/bar/baz.bill');

echo $path_info['extension']; // "bill"

$.active returns the number of active Ajax requests.

I transposed this into Xamarin:

private static UIImage FixImageOrientation(UIImage image)

So, what's wrong with checking each element iteratively?

function arraysEqual(arr1, arr2) {
    if(arr1.length !== arr2.length)
        return false;
    for(var i = arr1.length; i--;) {
        if(arr1[i] !== arr2[i])
            return false;
    }

    return true;
}

If anyone is interested in doing something like this in Swift these days, I have a start on something, although it's not perfect.

func detectDate(dateString: NSString) -> NSDate {

    var error: NSError?
    let detector: NSDataDetector = NSDataDetector.dataDetectorWithTypes(NSTextCheckingType.Date.toRaw(), error: &error)!

    if error == nil {
        var matches = detector.matchesInString(dateString, options: nil, range: NSMakeRange(0, dateString.length))

        let currentLocale = NSLocale.currentLocale()
        for match in matches {
            match.resultType == NSTextCheckingType.Date
            NSLog("Date: \(match.date.description)")
            return match.date
        }
    }
    return NSDate()

When you call for i in a:, you are getting the actual elements, not the indexes. When we reach the last element, that is 3, b.append(a[i+1]-a[i]) looks for a[4], doesn't find one and then fails. Instead, try iterating over the indexes while stopping just short of the last one, like

for i in range(0, len(a)-1): Do something

Your current code won't work yet for the do something part though ;)

NULL values are stored separately in a special bitmap space for all the columns.

If you do not distinguish between NULL and '' in your application, then I would recommend you to store '' in your tables (unless the string column is a foreign key, in which case it would probably be better to prohibit the column from storing empty strings and allow the NULLs, if that is compatible with the logic of your application).

It can be resolved by below simple code with Stream and Try in AbacusUtil:

Stream.of(accounts).filter(a -> Try.call(a::isActive)).map(a -> Try.call(a::getNumber)).toSet();

Disclosure: I'm the developer of AbacusUtil.

public abstract class Draw {
    public abstract void drawShape(); // this is abstraction.  Implementation detail need not to be known.
    // so we are providing only necessary detail by giving drawShape(); No implementation. Subclass will give detail.


    private int type;    // this variable cannot be set outside of the class. Because it is private.
    // Binding private instance variable with public setter/getter method is encapsulation 

    public int getType() { 
        return type;
    }

    public void setType(int type) {  // this is encapsulation. Protecting any value to be set.
        if (type >= 0 && type <= 3) {
            this.type = type;
        } else {
            System.out.println("We have four types only. Enter value between 0 to 4");
            try {
                throw new MyInvalidValueSetException();
            } catch (MyInvalidValueSetException e) {
                e.printStackTrace();
            }

        }
    }
}

Abstraction is related with methods where implementation detail is not known which is a kind of implementation hiding.
Encapsulation is related with instance variable binding with method, a kind of data hiding.

If you use Express 4.x, you can use the req.get(headerName) method as described in Express 4.x API Reference

The problem with realpath is that it is not available on BSD (or OSX for that matter). Here is a simple recipe extracted from a rather old (2009) article from Linux Journal, that is quite portable:

function normpath() {
  # Remove all /./ sequences.
  local path=${1//\/.\//\/}

  # Remove dir/.. sequences.
  while [[ $path =~ ([^/][^/]*/\.\./) ]]; do
    path=${path/${BASH_REMATCH[0]}/}
  done
  echo $path
}

Notice this variant also does not require the path to exist.

Use the synaptic packet manager in order to install yacc / lex. If you are feeling more comfortable doing this on the console just do:

sudo apt-get install bison flex

There are some very nice articles on the net on how to get started with those tools. I found the article from CodeProject to be quite good and helpful (see here). But you should just try and search for "introduction to lex", there are plenty of good articles showing up.

Val - values are typed storage constants. Once created its value cant be re-assigned. a new value can be defined with keyword val.

eg. val x: Int = 5

Here type is optional as scala can infer it from the assigned value.

Var - variables are typed storage units which can be assigned values again as long as memory space is reserved.

eg. var x: Int = 5

Data stored in both the storage units are automatically de-allocated by JVM once these are no longer needed.

In scala values are preferred over variables due to stability these brings to the code particularly in concurrent and multithreaded code.

Recursive convert object to array

    for (var key in obj) {

        tempObject = obj[key];

        if (is_object(obj[key])) {
            tempObject = objectToArray(obj[key]);

        array[key] = tempObject;

Don't know for sure, but it sounds like it is still submitting. I quick solution would be to change your (guessing at your code here):

<input type="submit" value="Submit" onclick="checkform()">

to a button:

<input type="button" value="Submit" onclick="checkform()">

That way your form still gets submitted (from the else part of your checkform()) and it shouldn't be reloading the page.

There are other, perhaps better, ways of handling it but this works in the mean time.

Just use date and trusty seconds:

As you rightly point out, a lot of the details about the underlying computation are hidden if you rely on English time arithmetic. E.g. -d yesterday, and -d 1 day ago will have different behaviour.

Instead, you can reliably depend on the (precisely documented) seconds since the unix epoch UTC, and bash arithmetic to obtain the moment you want:

date -d @$(( $(date +"%s") - 24*3600)) +"%Y-%m-%d"

This was pointed out in another answer. This form is more portable across platforms with different date command line flags, is language-independent (e.g. "yesterday" vs "hier" in French locale), and frankly (in the long-term) will be easier to remember, because well, you know it already. You might otherwise keep asking yourself: "Was it -d 2 hours ago or -d 2 hour ago again?" or "Is it -d yesterday or -d 1 day ago that I want?"). The only tricky bit here is the @.

Armed with bash and nothing else:

Bash solely on bash, you can also get yesterday's time, via the printf builtin:

 %(datefmt)T
     causes printf to output the date-time string resulting from using
     datefmt as a format string for strftime(3).  The  corresponding  argu-
     ment  is an integer representing the number of seconds since the
     epoch.  Two special argument values may be used: -1 represents the
     current time, and -2 represents the time the shell was invoked.
     If no argument is specified, conversion behaves as if -1 had
     been  given.
     This is an exception to the usual printf behavior.

So,

# inner printf gets you the current unix time in seconds
# outer printf spits it out according to the format
printf "%(%Y-%m-%d)T\n" $(( $(printf "%(%s)T" -1) - 24*3600 ))

or, equivalently with a temp variable (outer subshell optional, but keeps environment vars clean).

(
  now=$(printf "%(%s)T" -1);
  printf "%(%Y-%m-%d)T\n" $((now - 24*3600));
)

Note: despite the manpage stating that no argument to the %()T formatter will assume a default -1, i seem to get a 0 instead (thank you, bash manual version 4.3.48)

git reset HEAD~1 if you don't want your changes to be gone(unstaged changes). Change, commit and push again git push -f [origin] [branch]

Note : Use it if calculating / adding days from current date.

Be aware: this answer has issues (see comments)

var myDate = new Date();
myDate.setDate(myDate.getDate() + AddDaysHere);

It should be like

var newDate = new Date(date.setTime( date.getTime() + days * 86400000 ));

There is no simple command available to find out the largest files/directories on a Linux/UNIX/BSD filesystem. However, combination of following three commands (using pipes) you can easily find out list of largest files:

# du -a /var | sort -n -r | head -n 10

If you want more human readable output try:

$ cd /path/to/some/var
$ du -hsx * | sort -rh | head -10

Where,

• Var is the directory you wan to search
• du command -h option : display sizes in human readable format (e.g., 1K, 234M, 2G).
• du command -s option : show only a total for each argument (summary).
• du command -x option : skip directories on different file systems.
• sort command -r option : reverse the result of comparisons.
• sort command -h option : compare human readable numbers. This is GNU sort specific option only.
• head command -10 OR -n 10 option : show the first 10 lines.

Here is an update to @GiridharKamik answer above with the latest version of Rxjs.

import { Injectable } from '@angular/core';
import { Observable, BehaviorSubject, fromEvent } from 'rxjs';
import { pluck, distinctUntilChanged, map } from 'rxjs/operators';

@Injectable()
export class WindowService {
    height$: Observable<number>;
    constructor() {
        const windowSize$ = new BehaviorSubject(getWindowSize());

        this.height$ = windowSize$.pipe(pluck('height'), distinctUntilChanged());

        fromEvent(window, 'resize').pipe(map(getWindowSize))
            .subscribe(windowSize$);
    }

}

function getWindowSize() {
    return {
        height: window.innerHeight
        //you can sense other parameters here
    };
};

A solution with ggplot2 :

qplot(x,y)+geom_errorbar(aes(x=x, ymin=y-sd, ymax=y+sd), width=0.25)

The default limit for the length of the request line is 8190 bytes (see LimitRequestLine directive). And if we subtract three bytes for the request method (i.e. GET), eight bytes for the version information (i.e. HTTP/1.0/HTTP/1.1) and two bytes for the separating space, we end up with 8177 bytes for the URI path plus query.

It appears that ng-options is complicated (possibly frustrating) to use, but in reality we have an architecture problem.

AngularJS serves as an MVC framework for a dynamic HTML+JavaScript application. While its (V)iew component does offer HTML "templating," its primary purpose is to connect user actions, via a controller, to changes in the model. Therefore the appropriate level of abstraction, from which to work in AngularJS, is that a select element sets a value in the model to a value from a query.

• How a query row is presented to the user is the (V)iew’s concern and ng-options provides the for keyword to dictate what the contents of the option element should be i.e. p.text for p in resultOptions.
• How a selected row is presented to the server is the (M)odel’s concern. Therefore ng-options provides the as keyword to specify what value is provided to the model as in k as v for (k,v) in objects.

The correct solution this is problem is then architectural in nature and involves refactoring your HTML so that the (M)odel performs server communication when required (instead of the user submitting a form).

If an MVC HTML page is unnecessary over-engineering for the problem at hand: then use only the HTML generation portion of AngularJS’s (V)iew component. In this case, follow the same pattern that is used for generating elements such as <li />'s under <ul />'s and place a ng-repeat on an option element:

<select name=“value”>
    <option ng-repeat=“value in Model.Values” value=“{{value.value}}”>
        {{value.text}}
    </option>
</select>

As kludge, one can always move the name attribute of the select element to a hidden input element:

<select ng-model=“selectedValue” ng-options=“value.text for value in Model.Values”>
</select>
<input type=“hidden” name=“value” value=“{{selectedValue}}” />

When a log scale is used the number of major ticks can be fixed with the following command

import matplotlib.pyplot as plt

....

plt.locator_params(numticks=12)
plt.show()

The value set to numticks determines the number of axis ticks to be displayed.

Credits to @bgamari's post for introducing the locator_params() function, but the nticks parameter throws an error when a log scale is used.

std::copy cannot be used to insert into an empty container. To do that, you need to use an insert_iterator like so:

std::set<double> input;
input.insert(5);
input.insert(6);

std::vector<double> output;
std::copy(input.begin(), input.end(), inserter(output, output.begin())); 

In python 2.7, the / operator is integer division if inputs are integers.

If you want float division (which is something I always prefer), just use this special import:

from __future__ import division

See it here:

>>> 7 / 2
3
>>> from __future__ import division
>>> 7 / 2
3.5
>>>

Integer division is achieved by using //, and modulo by using %

>>> 7 % 2
1
>>> 7 // 2
3
>>>

EDIT

As commented by user2357112, this import has to be done before any other normal import.

There is this tool ChangeVersion ^[1]

• easy to integrate into a continuous build environment

Full Disclosure: I know the guy who wrote this tool, I used to work with him. But this also means that I know he makes quality software ;)

^[1] the link is dead. There seems to be mirrored version at download.cnet.com.

Unset will destroy a particular session variable whereas session_destroy() will destroy all the session data for that user.

It really depends on your application as to which one you should use. Just keep the above in mind.

unset($_SESSION['name']); // will delete just the name data

session_destroy(); // will delete ALL data associated with that user.

For those still having issues with Renderscript support library on x86 chipsets, please have a look at this post by the creator of the library. It looks like the fix he prepared didn't make it somehow to the Build Tools v20.0.0, so he provides the files to fix it manually and a brief explanation of how to do it.

From the manual:

Possible values for the parameter timeout: … x set timeout to x seconds

and

readlines(sizehint=None, eol='\n') Read a list of lines, until timeout. sizehint is ignored and only present for API compatibility with built-in File objects.

Note that this function only returns on a timeout.

So your readlines will return at most every 2 seconds. Use read() as Tim suggested.

Problem Statement
It's possible to write LINQ to SQL that gets all rows that have either null or an empty string in a given field, but it's not possible to use string.IsNullOrEmpty to do it, even though many other string methods map to LINQ to SQL. Proposed Solution Allow string.IsNullOrEmpty in a LINQ to SQL where clause so that these two queries have the same result:

var fieldNullOrEmpty =
from item in db.SomeTable
where item.SomeField == null || item.SomeField.Equals(string.Empty)
select item;

var fieldNullOrEmpty2 =
from item in db.SomeTable
where string.IsNullOrEmpty(item.SomeField)
select item;

If you want to use the version of Javascript called ES 2015 (aka ES6) or later, you can use template strings introduced by ES 2015 and recommended by some guidelines (like Airbnb's style guide):

const after = "test";
const mystr = `This is: ${after}`;

If you use apachectl to start or stop, then you can find it with this command

apachectl -t -D DUMP_RUN_CFG

You can use numpy library (works for Python2.x only):

   import numpy as np 

   list_of_unique_dicts=list(np.unique(np.array(list_of_dicts)))

To get it worked with Python 3.x (and recent versions of numpy), you need to convert array of dicts to numpy array of strings, e.g.

list_of_unique_dicts=list(np.unique(np.array(list_of_dicts).astype(str)))

If the problem lies client side, this could be one of the causes of the error.

Actually this is a problem of Tomcat. Just go to 'lib' folder of your project and copy your all 'Spring' related jars into this. Refresh your project and you are all good to go. This problem sometime persists because tomcat is unable to locate Spring core classes.

After some searching I found this on a Google groups discussion:

docker currently inhibits this capability for enhanced safety.

That is because the ulimit settings of the host system apply to the docker container. It is regarded as a security risk that programs running in a container can change the ulimit settings for the host.

The good news is that you have two different solutions to choose from.

1. Remove sys_resource from lxc_template.go and recompile docker. Then you'll be able to set the ulimit as high as you like.

or

2. Stop the docker demon. Change the ulimit settings on the host. Start the docker demon. It now has your revised limits, and its child processes as well.

I applied the second method:

1. sudo service docker stop;

2. changed the limits in /etc/security/limits.conf

3. reboot the machine

4. run my container

5. run ulimit -a in the container to confirm the open files limit has been inherited.

future.utils allows for python 2 and 3 compatibility.

    print(key,value)

>>> ('lady', 165)
>>> ('man', 185)

I will show visually the problem, using the great example from James answer and adding the alternative solution.

When you do the follow query, without the FETCH:

Select e from Employee e 
join e.phones p 
where p.areaCode = '613'

You will have the follow results from Employee as you expected:

But when you add the FETCH word on JOIN, this is what happens:

The generated SQL is the same for the two queries, but the Hibernate removes on memory the 416 register when you use WHERE on the FETCH join.

So, to bring all phones and apply the WHERE correctly, you need to have two JOINs: one for the WHERE and another for the FETCH. Like:

Select e from Employee e 
join e.phones p 
join fetch e.phones      //no alias, to not commit the mistake
where p.areaCode = '613'

The first one catches all subclasses of Throwable (this includes Exception and Error), the second one catches all subclasses of Exception.

Error is programmatically unrecoverable in any way and is usually not to be caught, except for logging purposes (which passes it through again). Exception is programmatically recoverable. Its subclass RuntimeException indicates a programming error and is usually not to be caught as well.

I would use FMOD to do this for your game. It has the ability to play any file mostly for sounds and is pretty simple to implement in C++. using FMOD and Dir3ect X together can be powerful and not that difficult. If you are familiar with Singleton classes I would create a Singleton class of a sound manager in your win main cpp and then have access to it whenever to load or play new music or sound effects. here's an audio manager example

For my console program the answers with tkinter above did not quite work for me because the .destroy() always gave an error,:

can't invoke "event" command: application has been destroyed while executing...

or when using .withdraw() the console window did not get the focus back.

To solve this you also have to call .update() before the .destroy(). Example:

# Python 3
import tkinter

r = tkinter.Tk()
text = r.clipboard_get()
r.withdraw()
r.update()
r.destroy()

The r.withdraw() prevents the frame from showing for a milisecond, and then it will be destroyed giving the focus back to the console.

1) Add any remote repositories you want to compare:

git remote add foobar git://github.com/user/foobar.git

2) Update your local copy of a remote:

git fetch foobar

Fetch won't change your working copy.

3) Compare any branch from your local repository to any remote you've added:

git diff master foobar/master

That very well may be a false positive. Like the warning message says, it is common for a capture to start in the middle of a tcp session. In those cases it does not have that information. If you are really missing acks then it is time to start looking upstream from your host for where they are disappearing. It is possible that tshark can not keep up with the data and so it is dropping some metrics. At the end of your capture it will tell you if the "kernel dropped packet" and how many. By default tshark disables dns lookup, tcpdump does not. If you use tcpdump you need to pass in the "-n" switch. If you are having a disk IO issue then you can do something like write to memory /dev/shm. BUT be careful because if your captures get very large then you can cause your machine to start swapping.

My bet is that you have some very long running tcp sessions and when you start your capture you are simply missing some parts of the tcp session due to that. Having said that, here are some of the things that I have seen cause duplicate/missing acks.

1. Switches - (very unlikely but sometimes they get in a sick state)
2. Routers - more likely than switches, but not much
3. Firewall - More likely than routers. Things to look for here are resource exhaustion (license, cpu, etc)
4. Client side filtering software - antivirus, malware detection etc.

}

I coincidentally found out that Break <UnknownLabel> (e.g. simply Break Script, where the label Script doesn't exists) appears to break out of the entire script (even from within a function) and keeps the host alive.
This way you could create a function that breaks the script from anywhere (e.g. a recursive loop) without knowing the current scope (and creating labels):

Function Quit($Text) {
    Write-Host "Quiting because: " $Text
    Break Script
} 

I ran into the same type of error you described, but mine was due to the dom not being completely ready to go. I tested with both jQuery pulling the div and also getElementById just to make sure there wasn't something strange with the jQuery selector. Below is an example that works in Chrome:

There might be a problem with your DNS servers of the ISP. A computer by default uses the ISP's DNS servers. You can manually configure your DNS servers. It is free and usually better than your ISP.

1. Go to Control Panel ? Network and Internet ? Network and Sharing Centre
2. Click on Change Adapter settings.
3. Right click on your connection icon (Wireless Network Connection or Local Area Connection) and select properties.
4. Select Internet protocol version 4.
5. Click on "Use the following DNS server address" and type either of the two DNS given below.

Google Public DNS

Preferred DNS server : 8.8.8.8

As others have already mentioned, running PHP as a daemon is quite easy, and can be done using a single line of command. But the actual problem is keeping it running and managing it. I've had the same problem quite some time ago and although there are plenty of solutions already available, most of them have lots of dependencies or are difficult to use and not suitable for basic usages. I wrote a shell script that can manage a any process/application including PHP cli scripts. It can be set as a cronjob to start the application and will contain the application and manage it. If it's executed again, for example via the same cronjob, it check if the app is running or not, if it does then simply exits and let its previous instance continue managing the application.

I uploaded it to github, feel free to use it : https://github.com/sinasalek/EasyDeamonizer

EasyDeamonizer

Simply watches over your application (start, restart, log, monitor, etc). a generic script to make sure that your appliation remains running properly. Intentionally it uses process name instread of pid/lock file to prevent all its side effects and keep the script as simple and as stirghforward as possible, so it always works even when EasyDaemonizer itself is restarted. Features

• Starts the application and optionally a customized delay for each start
• Makes sure that only one instance is running
• Monitors CPU usage and restarts the app automatically when it reaches the defined threshold
• Setting EasyDeamonizer to run via cron to run it again if it's halted for any reason
• Logs its activity

This should works too. First create an absolute <div> element with absolute position and 100% height:

<div id="h" style="position:absolute;top:0;bottom:0;"></div>

Then, get the window height from that element via offsetHeight

var winHeight = document.getElementById('h').offsetHeight;

Update:

function getBrowserSize() {
    var div = document.createElement('div');
    div.style.position = 'absolute';
    div.style.top = 0;
    div.style.left = 0;
    div.style.width = '100%';
    div.style.height = '100%';
    document.documentElement.appendChild(div);
    var results = {
        width: div.offsetWidth,
        height: div.offsetHeight
    };
    div.parentNode.removeChild(div); // remove the `div`
    return results;
}

console.log(getBrowserSize());

I prefer this syntax as it allows to set configuration parameters for the shell:

---
- name: an example
  shell:
    cmd: |
      docker build -t current_dir .
      echo "Hello World"
      date

    chdir: /home/vagrant/

The main difference is that var variable value can change, and let can't. If you want to have a user input data, you would use var so the value can be changed and use let datatype variable so the value can not be changed.

var str      = "dog"  // str value is "dog"
str          = "cat"  // str value is now "cat"

let strAnimal = "dog" // strAnimal value is "dog"
strAnimal     = "cat" // Error !

You can do that like this:

from datetime import datetime
from threading import Timer

x=datetime.today()
y=x.replace(day=x.day+1, hour=1, minute=0, second=0, microsecond=0)
delta_t=y-x

secs=delta_t.seconds+1

def hello_world():
    print "hello world"
    #...

t = Timer(secs, hello_world)
t.start()

This will execute a function (eg. hello_world) in the next day at 1a.m.

EDIT:

As suggested by @PaulMag, more generally, in order to detect if the day of the month must be reset due to the reaching of the end of the month, the definition of y in this context shall be the following:

y = x.replace(day=x.day, hour=1, minute=0, second=0, microsecond=0) + timedelta(days=1)

With this fix, it is also needed to add timedelta to the imports. The other code lines maintain the same. The full solution, using also the total_seconds() function, is therefore:

from datetime import datetime, timedelta
from threading import Timer

x=datetime.today()
y = x.replace(day=x.day, hour=1, minute=0, second=0, microsecond=0) + timedelta(days=1)
delta_t=y-x

secs=delta_t.total_seconds()

def hello_world():
    print "hello world"
    #...

t = Timer(secs, hello_world)
t.start()

zxing does not (only) provide a web API; really, that is Google providing the API, from source code that was later open-sourced in the project.

As Rob says here you can use the Java source code for the QR code encoder to create a raw barcode and then render it as a Bitmap.

I can offer an easier way still. You can call Barcode Scanner by Intent to encode a barcode. You need just a few lines of code, and two classes from the project, under android-integration. The main one is IntentIntegrator. Just call shareText().

In stead of parsing JSON you can do like followng:

$.ajax({
  ..
  dataType: 'json' // using json, jquery will make parse for  you
});

To access a property of your JSON do following:

data[0].name;

data[0].address;

Why you need data[0] because data is an array, so to its content retrieve you need data[0] (first element), which gives you an object {"name":"myName" ,"address": "myAddress" }.

And to access property of an object rule is:

Object.property

or sometimes

Object["property"] // in some case

So you need

data[0].name and so on to get what you want.

If you not

set dataType: json then you need to parse them using $.parseJSON() and to retrieve data like above.

1. Find out where Git thinks 'origin/master' is using git-remote

git remote show origin

..which will return something like..

* remote origin
  URL: [email protected]:~/something.git
  Remote branch merged with 'git pull' while on branch master
    master
  Tracked remote branch
    master

A remote is basically a link to a remote repository. When you do..

git remote add unfuddle [email protected]/myrepo.git
git push unfuddle

..git will push changes to that address you added. It's like a bookmark, for remote repositories.

When you run git status, it checks if the remote is missing commits (compared to your local repository), and if so, by how many commits. If you push all your changes to "origin", both will be in sync, so you wont get that message.

2. If it's somewhere else, how do I turn my laptop into the 'origin/master'?

There is no point in doing this. Say "origin" is renamed to "laptop" - you never want to do git push laptop from your laptop.

If you want to remove the origin remote, you do..

git remote rm origin

This wont delete anything (in terms of file-content/revisions-history). This will stop the "your branch is ahead by.." message, as it will no longer compare your repository with the remote (because it's gone!)

One thing to remember is that there is nothing special about origin, it's just a default name git uses.

Git does use origin by default when you do things like git push or git pull. So, if you have a remote you use a lot (Unfuddle, in your case), I would recommend adding unfuddle as "origin":

git remote rm origin
git remote add origin [email protected]:subdomain/abbreviation.git

or do the above in one command using set-url:

git remote set-url origin [email protected]:subdomain/abbreviation.git

Then you can simply do git push or git pull to update, instead of git push unfuddle master

You need to detect the click from js side, your HTML remaining same. Note: this method is deprecated since v3.5.5 and removed in v4.

$("button").click(function() {
    var $btn = $(this);
    $btn.button('loading');
    // simulating a timeout
    setTimeout(function () {
        $btn.button('reset');
    }, 1000);
});

Also, don't forget to load jQuery and Bootstrap js (based on jQuery) file in your page.

The alignment-baseline property is what you're looking for it can take the following values

auto | baseline | before-edge | text-before-edge | 
middle | central | after-edge | text-after-edge | 
ideographic | alphabetic | hanging | mathematical | 
inherit

Description from w3c

This property specifies how an object is aligned with respect to its parent. This property specifies which baseline of this element is to be aligned with the corresponding baseline of the parent. For example, this allows alphabetic baselines in Roman text to stay aligned across font size changes. It defaults to the baseline with the same name as the computed value of the alignment-baseline property. That is, the position of "ideographic" alignment-point in the block-progression-direction is the position of the "ideographic" baseline in the baseline-table of the object being aligned.

W3C Source

Unfortunately, although this is the "correct" way of achieving what you're after it would appear Firefox have not implemented a lot of the presentation attributes for the SVG Text Module ('SVG in Firefox' MDN Documentation)

private int[,] MirrorH(int[,] matrix)               //the method will return mirror horizintal of matrix
{
    int[,] MirrorHorizintal = new int[4, 4];
    for (int i = 0; i < 4; i++)
    {
        for (int j = 0; j < 4; j ++)
        {
            MirrorHorizintal[i, j] = matrix[i, 3 - j];
        }
    }
    return MirrorHorizintal;
}

In short, yes, the order is preserved. In long:

In general the following definitions will always apply to objects like lists:

A list is a collection of elements that can contain duplicate elements and has a defined order that generally does not change unless explicitly made to do so. stacks and queues are both types of lists that provide specific (often limited) behavior for adding and removing elements (stacks being LIFO, queues being FIFO). Lists are practical representations of, well, lists of things. A string can be thought of as a list of characters, as the order is important ("abc" != "bca") and duplicates in the content of the string are certainly permitted ("aaa" can exist and != "a").

A set is a collection of elements that cannot contain duplicates and has a non-definite order that may or may not change over time. Sets do not represent lists of things so much as they describe the extent of a certain selection of things. The internal structure of set, how its elements are stored relative to each other, is usually not meant to convey useful information. In some implementations, sets are always internally sorted; in others the ordering is simply undefined (usually depending on a hash function).

Collection is a generic term referring to any object used to store a (usually variable) number of other objects. Both lists and sets are a type of collection. Tuples and Arrays are normally not considered to be collections. Some languages consider maps (containers that describe associations between different objects) to be a type of collection as well.

This naming scheme holds true for all programming languages that I know of, including Python, C++, Java, C#, and Lisp (in which lists not keeping their order would be particularly catastrophic). If anyone knows of any where this is not the case, please just say so and I'll edit my answer. Note that specific implementations may use other names for these objects, such as vector in C++ and flex in ALGOL 68 (both lists; flex is technically just a re-sizable array).

If there is any confusion left in your case due to the specifics of how the + sign works here, just know that order is important for lists and unless there is very good reason to believe otherwise you can pretty much always safely assume that list operations preserve order. In this case, the + sign behaves much like it does for strings (which are really just lists of characters anyway): it takes the content of a list and places it behind the content of another.

If we have

list1 = [0, 1, 2, 3, 4]
list2 = [5, 6, 7, 8, 9]

Then

list1 + list2

Is the same as

[0, 1, 2, 3, 4] + [5, 6, 7, 8, 9]

Which evaluates to

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Much like

"abdcde" + "fghijk"

Produces

"abdcdefghijk"

If it isn't I could see things heading that way.

I'm working on redoing the website for the company I work for and the designer they hired used a 960px width layout. There is also a 960px grid system that seems to be getting quite popular (http://960.gs/).

I've been out of web stuff for a few years but from what I've read catching up on things it seems 960/980 is about right. For mobile ~320px sticks in my mind, by which 960 is divisible. 960 is also evenly divisible by 2, 3, 4, 5, and 6.

I've always thought that Encryption can be converted both ways, in a way that the end value can bring you to original value and with Hashing you'll not be able to revert from the end result to the original value.

All above solutions + extra sugar. (Ultimate AIO solution)

/**
 * Check that given URL is valid and exists.
 * @param string $url URL to check
 * @return bool TRUE when valid | FALSE anyway
 */
function urlExists ( $url ) {
    // Remove all illegal characters from a url
    $url = filter_var($url, FILTER_SANITIZE_URL);

    // Validate URI
    if (filter_var($url, FILTER_VALIDATE_URL) === FALSE
        // check only for http/https schemes.
        || !in_array(strtolower(parse_url($url, PHP_URL_SCHEME)), ['http','https'], true )
    ) {
        return false;
    }

    // Check that URL exists
    $file_headers = @get_headers($url);
    return !(!$file_headers || $file_headers[0] === 'HTTP/1.1 404 Not Found');
}

Example:

var_dump ( urlExists('http://stackoverflow.com/') );
// Output: true;

A couple of general tips (besides the DOS line ending issue):

cat is for concatenating files, it's not the only tool that can read files! If a command doesn't read files then use redirection like command < file.

You can set the field separator with the -F option so instead of:

cat foo | awk 'BEGIN{FS="|"} {print $2 " " $1}' 

Try:

awk -F'|' '{print $2" "$1}' foo 

This will output:

com.emailclient.account [email protected]
com.socialsite.auth.accoun [email protected]

To get the desired output you could do a variety of things. I'd probably split() the second field:

awk -F'|' '{split($2,a,".");print a[2]" "$1}' file
emailclient [email protected]
socialsite [email protected]

Finally to get the first character converted to uppercase is a bit of a pain in awk as you don't have a nice built in ucfirst() function:

awk -F'|' '{split($2,a,".");print toupper(substr(a[2],1,1)) substr(a[2],2),$1}' file
Emailclient [email protected]
Socialsite [email protected]

If you want something more concise (although you give up a sub-process) you could do:

awk -F'|' '{split($2,a,".");print a[2]" "$1}' file | sed 's/^./\U&/'
Emailclient [email protected]
Socialsite [email protected]

In AndroidManifest.xml, set android:theme="@android:style/Theme.NoTitleBar.Fullscreen"in application tag.

Individual activities can override the default by setting their own theme attributes.

Have you tried Tools > Formula Auditing?

An HTTP message may have a body of data sent after the header lines. In a response, this is where the requested resource is returned to the client (the most common use of the message body), or perhaps explanatory text if there's an error. In a request, this is where user-entered data or uploaded files are sent to the server.

A much easier solution: Using a dynamic type

As of Json.NET 4.0 Release 1, there is native dynamic support. You don't need to declare a class, just use dynamic :

dynamic jsonDe = JsonConvert.DeserializeObject(json);

All the fields will be available:

foreach (string typeStr in jsonDe.Type[0])
{
    // Do something with typeStr
} 

string t = jsonDe.t;
bool a = jsonDe.a;
object[] data = jsonDe.data;
string[][] type = jsonDe.Type;

With dynamic you don't need to create a specific class to hold your data.

string.find(character)  
string.index(character)  

Perhaps you'd like to have a look at the documentation to find out what the difference between the two is.

varchar, Don't store separating characters you may want to format the phone numbers differently for different uses. so store (619) 123-4567 as 6191234567 I work with phone directory data and have found this to be the best practice.

I'm using a kendo grid and therefore can't change the implementation to a getter method but I want to test around this (mocking the grid) and not test the grid itself. I was using a spy object but this doesn't support property mocking so I do this:

    this.$scope.ticketsGrid = { 
        showColumn: jasmine.createSpy('showColumn'),
        hideColumn: jasmine.createSpy('hideColumn'),
        select: jasmine.createSpy('select'),
        dataItem: jasmine.createSpy('dataItem'),
        _data: []
    } 

It's a bit long winded but it works a treat

Shortened version of @AnttiHaapala:

json.dumps(dict_with_sets, default=lambda x: list(x) if isinstance(x, set) else x)

If your program needs to run quickly, call value.ToString(formatString) for ~35% faster string formatting performance relative to $"{value:formatString}" and string.Format(formatString, value).

You could set the width of the abbrev column to a fixed pixel width, then set the width of the description column to the width of the DataGridView, minus the sum of the widths of the other columns and some extra margin (if you want to prevent a horizontal scrollbar from appearing on the DataGridView):

dataGridView1.Columns[1].Width = 108;  // or whatever width works well for abbrev
dataGridView1.Columns[2].Width = 
    dataGridView1.Width 
    - dataGridView1.Columns[0].Width 
    - dataGridView1.Columns[1].Width 
    - 72;  // this is an extra "margin" number of pixels

If you wanted the description column to always take up the "remainder" of the width of the DataGridView, you could put something like the above code in a Resize event handler of the DataGridView.

You should not include commands.c in your header file. In general, you should not include .c files. Rather, commands.c should include commands.h. As defined here, the C preprocessor is inserting the contents of commands.c into commands.h where the include is. You end up with two definitions of f123 in commands.h.

commands.h

#ifndef COMMANDS_H_
#define COMMANDS_H_

void f123();

#endif

commands.c

#include "commands.h"

void f123()
{
    /* code */
}

You can use strrchr() to find last occurence of .(dot) and get .(dot) based extensions files. Check the below code for example.

#include<stdio.h>

void GetFileExtension(const char* file_name) {

    int ext = '.';
    const char* extension = NULL;
    extension = strrchr(file_name, ext);

    if(extension == NULL){
        printf("Invalid extension encountered\n");
        return;
    }

    printf("File extension is %s\n", extension);
}

int main()
{
    const char* file_name = "c:\\.directoryname\\file.name.with.too.many.dots.ext";
    GetFileExtension(file_name);
    return 0;
}

I found that the include parameter needs to be the entire file path, not a relative path or partial path for this to work.

The Icon displayed in the Taskbar and Windowtitle is that of the main Form. By changing its Icon you also set the Icon shown in the Taskbar, when already included in your *.resx:

System.ComponentModel.ComponentResourceManager resources = 
    new System.ComponentModel.ComponentResourceManager(typeof(MyForm));
this.Icon = ((System.Drawing.Icon)(resources.GetObject("statusnormal.Icon")));

or, by directly reading from your Resources:

this.Icon = new Icon("Resources/statusnormal.ico");

If you cannot immediately find the code of the Form, search your whole project (CTRL+SHIFT+F) for the shown Window-Title (presuming that the text is static)

In the IndexProcessor class you need a way of setting a flag which informs the thread that it will need to terminate, similar to the variable run that you have used just in the class scope.

When you wish to stop the thread, you set this flag and call join() on the thread and wait for it to finish.

Make sure that the flag is thread safe by using a volatile variable or by using getter and setter methods which are synchronised with the variable being used as the flag.

public class IndexProcessor implements Runnable {

    private static final Logger LOGGER = LoggerFactory.getLogger(IndexProcessor.class);
    private volatile boolean running = true;

    public void terminate() {
        running = false;
    }

    @Override
    public void run() {
        while (running) {
            try {
                LOGGER.debug("Sleeping...");
                Thread.sleep((long) 15000);

                LOGGER.debug("Processing");
            } catch (InterruptedException e) {
                LOGGER.error("Exception", e);
                running = false;
            }
        }

    }
}

Then in SearchEngineContextListener:

public class SearchEngineContextListener implements ServletContextListener {

    private static final Logger LOGGER = LoggerFactory.getLogger(SearchEngineContextListener.class);

    private Thread thread = null;
    private IndexProcessor runnable = null;

    @Override
    public void contextInitialized(ServletContextEvent event) {
        runnable = new IndexProcessor();
        thread = new Thread(runnable);
        LOGGER.debug("Starting thread: " + thread);
        thread.start();
        LOGGER.debug("Background process successfully started.");
    }

    @Override
    public void contextDestroyed(ServletContextEvent event) {
        LOGGER.debug("Stopping thread: " + thread);
        if (thread != null) {
            runnable.terminate();
            thread.join();
            LOGGER.debug("Thread successfully stopped.");
        }
    }
}

Example of how to perform a INSERT INTO SELECT with a WHERE clause.

INSERT INTO #test2 (id) SELECT id FROM #test1 WHERE id > 2

Simply the response is already parsed, you don't need to parse it again. if you parse it again it will give you "unexpected token o" however you have to specify datatype in your request to be of type dataType='json'

I think you might not have the Android-18 sdk installed. Go to Tools > Android > SDK Manager and check to see if Android 4.3 (API 18) is installed.

Just to add to the solution presented, in my case I wanted to fetch multiple data from Firebase for a list of products. Here is how I did it:

useEffect(() => {
  const fn = p => firebase.firestore().doc(`products/${p.id}`).get();
  const actions = data.occasion.products.map(fn);
  const results = Promise.all(actions);
  results.then(data => {
    const newProducts = [];
    data.forEach(p => {
      newProducts.push({ id: p.id, ...p.data() });
    });
    setProducts(newProducts);
  });
}, [data]);

Easy:

print mystring[:100]

You can pass array of variables to the compact as an arguement eg:

return view('yourView', compact(['var1','var2',....'varN']));

in view: if var1 is an object you can use it something like this

@foreach($var1 as $singleVar1)
    {{$singleVar1->property}}
@endforeach

incase of single variable you can simply

{{$var2}}

i have done this several times without any issues

python manage.py flush

deleted old db contents,

Don't forget to create new superuser:

python manage.py createsuperuser

I encountered this error when inheriting from an abstract class and not implementing all of the pure virtual methods in my subclass.

Since Java 8, it seems like the java.time standard library is the way to go. From Joda time web page:

Note that from Java SE 8 onwards, users are asked to migrate to java.time (JSR-310) - a core part of the JDK which replaces this project.

Back to your question. Were you to use Java 8, I think you want LocalDateTime. Because it contains the date and time-of-the-day, but is unaware of time zone or any reference point in time such as the unix epoch.

I'm not aware of any way to do it using the standard library. But I do know and use this class that deals with html entities.

"HTMLEntities is an Open Source Java class that contains a collection of static methods (htmlentities, unhtmlentities, ...) to convert special and extended characters into HTML entitities and vice versa."

http://www.tecnick.com/public/code/cp_dpage.php?aiocp_dp=htmlentities

• Inner join - An inner join using either of the equivalent queries gives the intersection of the two tables, i.e. the two rows they have in common.

• Left outer join - A left outer join will give all rows in A, plus any common rows in B.

• Full outer join - A full outer join will give you the union of A and B, i.e. All the rows in A and all the rows in B. If something in A doesn't have a corresponding datum in B, then the B portion is null, and vice versay

This approach is fairly straight-forward once you get over the lambda gobbly-gook:

public static TProperty GetPropertyOrDefault<TObject, TProperty>(this TObject model, Func<TObject, TProperty> valueFunc)  
                                                        where TObject : class
    {
        try
        {
            return valueFunc.Invoke(model);
        }
        catch (NullReferenceException nex)
        {
            return default(TProperty);
        }
    }

With usage that might look like:

ObjectA objectA = null;

Assert.AreEqual(0,objectA.GetPropertyOrDefault(prop=>prop.ObjectB.ObjectB.ObjectC.ID));

Assert.IsNull(objectA.GetPropertyOrDefault(prop => prop.ObjectB));

Use this code:

internal void SomeFunction() {
    Dictionary<string, string> formField = new Dictionary<string, string>();
    
    formField.Add("Name", "Henry");
    formField.Add("Age", "21");
    
    string body = GetBodyStringFromDictionary(formField);
    // output : Name=Henry&Age=21
}

internal string GetBodyStringFromDictionary(Dictionary<string, string> formField)
{
    string body = string.Empty;
    foreach (var pair in formField)
    {
        body += $"{pair.Key}={pair.Value}&";   
    }

    // delete last "&"
    body = body.Substring(0, body.Length - 1);

    return body;
}

As stated by Luke you need to use a server side language, like php. This is a really simple php example:

<?php
if ($_GET['run']) {
  # This code will run if ?run=true is set.
  exec("/path/to/name.sh");
}
?>

<!-- This link will add ?run=true to your URL, myfilename.php?run=true -->
<a href="?run=true">Click Me!</a>

Save this as myfilename.php and place it on a machine with a web server with php installed. The same thing can be accomplished with asp, java, ruby, python, ...

Here's an alternative solution using requests:

import requests
wjdata = requests.get('url').json()
print wjdata['data']['current_condition'][0]['temp_C']

On Version 1.9.6.1. For UnPushed commit.

1. Click on previously committed description
2. Click Commit icon
3. Enter new commit message, and choose "Ammend latest commit" from the Commit options dropdown.
4. Commit your message.

I think we can improve the best answer a little bit, I'm using:

len = sum(1 for _ in reader)

Moreover, we shouldnt forget pythonic code not always have the best performance in the project. In example: If we can do more operations at the same time in the same data set Its better to do all in the same bucle instead make two or more pythonic bucles.

I use it like this:

switch (true){
     case /Pressure/.test(sensor): 
     {
        console.log('Its pressure!');
        break;
     }

     case /Temperature/.test(sensor): 
     {
        console.log('Its temperature!');
        break;
     }
}

This is probably one of the fastest way to remove permanently the duplicates from an array 10x times faster than the most functions here.& 78x faster in safari

function toUnique(a,b,c){//array,placeholder,placeholder
 b=a.length;
 while(c=--b)while(c--)a[b]!==a[c]||a.splice(c,1)
}
var array=[1,2,3,4,5,6,7,8,9,0,1,2,1];
toUnique(array);
console.log(array);

if you can't read the code above ask, read a javascript book or here are some explainations about shorter code. https://stackoverflow.com/a/21353032/2450730

EDIT As stated in the comments this function does return an array with uniques, the question however asks to find the duplicates. in that case a simple modification to this function allows to push the duplicates into an array, then using the previous function toUnique removes the duplicates of the duplicates.

function theDuplicates(a,b,c,d){//array,placeholder,placeholder
 b=a.length,d=[];
 while(c=--b)while(c--)a[b]!==a[c]||d.push(a.splice(c,1))
}
var array=[1,2,3,4,5,6,7,8,9,0,1,2,1];

toUnique(theDuplicates(array));

Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -sign before value:

ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) + 
  geom_bar(stat = "identity")

which gives:

Used data:

corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
                         variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
                         value = c(7L, 75L, 70L, 5L, 10L, 47L)),
                    class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))

The problem was a missing dependency that wasn't on the server but was on my local machine. In our case, it was a Devart.Data.Linq dll.

To get to that answer, I turned on IIS tracing for 500 errors. That gave a little bit of information, but the really helpful thing was in the web.config setting the <system.web><customErrors mode="Off"/></system.web> This pointed to a missing dynamically-loaded dependency. After adding this dependency and telling it to be copied locally, the server started working.

The use of http.createClient is now deprecated. You can pass Headers in options collection as below.

var options = { 
    hostname: 'example.com',
    path: '/somePath.php',
    method: 'GET',
    headers: {'Cookie': 'myCookie=myvalue'}
};
var results = ''; 
var req = http.request(options, function(res) {
    res.on('data', function (chunk) {
        results = results + chunk;
        //TODO
    }); 
    res.on('end', function () {
        //TODO
    }); 
});

req.on('error', function(e) {
        //TODO
});

req.end();

I have used Excel.dll library which is:

• open source
• lightweight
• fast
• compatible with xls and xlsx

The documentation available over here: https://exceldatareader.codeplex.com/

Strongly recommendable.

This is another way:

{{some_str | limitTo:1 | uppercase}}{{some_str.substr(1) | lowercase }}

The string $.datepicker.regional['it'] not translate all words.

For translate the datepicker you must specify some variables:

$.datepicker.regional['it'] = {
    closeText: 'Chiudi', // set a close button text
    currentText: 'Oggi', // set today text
    monthNames: ['Gennaio','Febbraio','Marzo','Aprile','Maggio','Giugno',   'Luglio','Agosto','Settembre','Ottobre','Novembre','Dicembre'], // set month names
    monthNamesShort: ['Gen','Feb','Mar','Apr','Mag','Giu','Lug','Ago','Set','Ott','Nov','Dic'], // set short month names
    dayNames: ['Domenica','Luned&#236','Marted&#236','Mercoled&#236','Gioved&#236','Venerd&#236','Sabato'], // set days names
    dayNamesShort: ['Dom','Lun','Mar','Mer','Gio','Ven','Sab'], // set short day names
    dayNamesMin: ['Do','Lu','Ma','Me','Gio','Ve','Sa'], // set more short days names
    dateFormat: 'dd/mm/yy' // set format date
};

$.datepicker.setDefaults($.datepicker.regional['it']);

$(".datepicker").datepicker();

In this case your datepicker is properly translated.

Use one of these as per your requirements.

The issue is with

• how ES6 modules are emulated in CommonJS
• how you import the module

ES6 to CommonJS

At the time of writing this, no environment supports ES6 modules natively. When using them in Node.js you need to use something like Babel to convert the modules to CommonJS. But how exactly does that happen?

Many people consider module.exports = ... to be equivalent to export default ... and exports.foo ... to be equivalent to export const foo = .... That's not quite true though, or at least not how Babel does it.

ES6 default exports are actually also named exports, except that default is a "reserved" name and there is special syntax support for it. Lets have a look how Babel compiles named and default exports:

// input
export const foo = 42;
export default 21;

// output
"use strict";

Object.defineProperty(exports, "__esModule", {
  value: true
});
var foo = exports.foo = 42;
exports.default = 21; 

Here we can see that the default export becomes a property on the exports object, just like foo.

Import the module

We can import the module in two ways: Either using CommonJS or using ES6 import syntax.

Your issue: I believe you are doing something like:

var bar = require('./input');
new bar();

expecting that bar is assigned the value of the default export. But as we can see in the example above, the default export is assigned to the default property!

So in order to access the default export we actually have to do

var bar = require('./input').default;

If we use ES6 module syntax, namely

import bar from './input';
console.log(bar);

Babel will transform it to

'use strict';

var _input = require('./input');

var _input2 = _interopRequireDefault(_input);

function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; }

console.log(_input2.default);

You can see that every access to bar is converted to access .default.

PID is the process ID - not the port number. You need to look for an entry with ":8080" at the end of the address/port part (the second column). Then you can look at the PID and use Task Manager to work out which process is involved... or run netstat -abn which will show the process names (but must be run under an administrator account).

Having said that, I would expect the find "8080" to find it...

Another thing to do is just visit http://localhost:8080 - on that port, chances are it's a web server of some description.

Since attribute values may contain a plain > character, try this regular expression:

$pattern = '/<'.preg_quote($tagname, '/').'(?:[^"'>]*|"[^"]*"|\'[^\']*\')*>(.*?)<\/'.preg_quote($tagname, '/').'>/s';

But regular expressions are not suitable for parsing non-regular languages like HTML. You should better use a parser like SimpleXML or DOMDocument.

If sleep.sh has the shebang #!/bin/sh and it has appropriate file permissions -- run chmod u+rx sleep.sh to make sure and it is in $PATH then your code should work as is:

import subprocess

rc = subprocess.call("sleep.sh")

If the script is not in the PATH then specify the full path to it e.g., if it is in the current working directory:

from subprocess import call

rc = call("./sleep.sh")

If the script has no shebang then you need to specify shell=True:

rc = call("./sleep.sh", shell=True)

If the script has no executable permissions and you can't change it e.g., by running os.chmod('sleep.sh', 0o755) then you could read the script as a text file and pass the string to subprocess module instead:

with open('sleep.sh', 'rb') as file:
    script = file.read()
rc = call(script, shell=True)

I got the same problem before, but I change the url into this

You can turn on your PHP errors with error_reporting:

error_reporting(E_ALL);
ini_set('display_errors', 'on');

Edit: It's possible that even after putting this, errors still don't show up. This can be caused if there is a fatal error in the script. From PHP Runtime Configuration:

Although display_errors may be set at runtime (with ini_set()), it won't have any affect if the script has fatal errors. This is because the desired runtime action does not get executed.

You should set display_errors = 1 in your php.ini file and restart the server.

Nodemon emits events upon every change in state; start, restart crash, etc. You can add a Nodemon configuration file (nodemon.json) like so:

{
   "events": {
       "start": "npm run *your_file*"
   }
}

Read more in Nodemon events — run tasks at server start, restart, crash, exit.

One way is to simply destroy the listener once you are done with it.

var removeListener = $scope.$on('navBarRight-ready', function () {
        $rootScope.$broadcast('workerProfile-display', $scope.worker)
        removeListener(); //destroy the listener
    })

So to make your expression work, changing && for -a will do the trick.

It is correct like this:

 if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
 then  ....

or like

 if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
 then  ....

or even

 if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
 then  ....

You can find further details in this question bash : Multiple Unary operators in if statement and some references given there like What is the difference between test, [ and [[ ?.

Won't work for every, but this just saved me a bunch of time. I just had the problem with a CSV returning "TRUE or "FALSE" so I just added VALUE.to_s.downcase == "true" which will return the boolean true if the value is "TRUE" and false if the value is "FALSE", but will still work for the boolean true and false.
