I had to split a list for feature extraction in two parts lt,lc:

ltexts = ((df4.ix[0:,[3,7]]).values).tolist()
random.shuffle(ltexts)

featsets = [(act_features((lt)),lc) 
              for lc, lt in ltexts]

def act_features(atext):
  features = {}
  for word in nltk.word_tokenize(atext):
     features['cont({})'.format(word.lower())]=True
  return features

I know nothing about Jenkins, but it looks like you are trying to access environment variables using some form of unix syntax - that won't work.

If the name of the variable is WORKSPACE, then the value is expanded in Windows batch using
%WORKSPACE%. That form of expansion is performed at parse time. For example, this will print to screen the value of WORKSPACE

echo %WORKSPACE%

If you need the value at execution time, then you need to use delayed expansion !WORKSPACE!. Delayed expansion is not normally enabled by default. Use SETLOCAL EnableDelayedExpansion to enable it. Delayed expansion is often needed because blocks of code within parentheses and/or multiple commands concatenated by &, &&, or || are parsed all at once, so a value assigned within the block cannot be read later within the same block unless you use delayed expansion.

setlocal enableDelayedExpansion
set WORKSPACE=BEFORE
(
  set WORKSPACE=AFTER
  echo Normal Expansion = %WORKSPACE%
  echo Delayed Expansion = !WORKSPACE!
)

The output of the above is

Normal Expansion = BEFORE
Delayed Expansion = AFTER

Use HELP SET or SET /? from the command line to get more information about Windows environment variables and the various expansion options. For example, it explains how to do search/replace and substring operations.

Here's a (Tested) Extension Method, with comments to help you out.

using IWshRuntimeLibrary;
using System;

namespace Extensions
{
    public static class XShortCut
    {
        /// <summary>

        /// <param name="startIn">The shortcut's "Start In" folder</param>
        /// <param name="description">The shortcut's description</param>
        /// <returns>The folder path where created</returns>
        public static string CreateShortCutInStartUpFolder(string exeName, string startIn, string description)
        {
            var startupFolderPath = Environment.SpecialFolder.Startup.GetFolderPath();
            var linkPath = startupFolderPath + @"\" + exeName + "-Shortcut.lnk";
            var targetPath = Environment.CurrentDirectory + @"\" + exeName;
            XFile.Delete(linkPath);
            Create(linkPath, targetPath, startIn, description);
            return startupFolderPath;
        }

        /// <summary>
        /// Create a shortcut
        /// </summary>
        /// <param name="fullPathToLink">the full path to the shortcut to be created</param>
        /// <param name="fullPathToTargetExe">the full path to the exe to 'really execute'</param>
        /// <param name="startIn">Start in this folder</param>
        /// <param name="description">Description for the link</param>
        public static void Create(string fullPathToLink, string fullPathToTargetExe, string startIn, string description)
        {
            var shell = new WshShell();
            var link = (IWshShortcut)shell.CreateShortcut(fullPathToLink);
            link.IconLocation = fullPathToTargetExe;
            link.TargetPath = fullPathToTargetExe;
            link.Description = description;
            link.WorkingDirectory = startIn;
            link.Save();
        }
    }
}

And an example of use:

XShortCut.CreateShortCutInStartUpFolder(THEEXENAME, 
    Environment.CurrentDirectory,
    "Starts some executable in the current directory of application");

1st parm sets the exe name (found in the current directory) 2nd parm is the "Start In" folder and 3rd parm is the shortcut description.

The naming convention of the link leaves no ambiguity as to what it will do. To test the link just double click it.

Final Note: the application itself (target) must have an ICON image associated with it. The link is easily able to locate the ICON within the exe. If the target application has more than one icon, you may open the link's properties and change the icon to any other found in the exe.

To replace the first occurrence of a pattern with a given string, use ${parameter/pattern/string}:

#!/bin/bash
firstString="I love Suzi and Marry"
secondString="Sara"
echo "${firstString/Suzi/$secondString}"    
# prints 'I love Sara and Marry'

To replace all occurrences, use ${parameter//pattern/string}:

message='The secret code is 12345'
echo "${message//[0-9]/X}"           
# prints 'The secret code is XXXXX'

(This is documented in the Bash Reference Manual, §3.5.3 "Shell Parameter Expansion".)

Note that this feature is not specified by POSIX — it's a Bash extension — so not all Unix shells implement it. For the relevant POSIX documentation, see The Open Group Technical Standard Base Specifications, Issue 7, the Shell & Utilities volume, §2.6.2 "Parameter Expansion".

Replace the line in htpasswd file:

Go to: http://www.htaccesstools.com/htpasswd-generator-windows/

(If the link is expired, search another generator from google.com.)

Enter your username and password. The site will generate an encrypted line. Copy that line and replace it with the previous line in the file "repo/htpasswd".

Return a tuple:

func getTime() -> (Int, Int, Int) {
    ...
    return ( hour, minute, second)
}

Then it's invoked as:

let (hour, minute, second) = getTime()

or:

let time = getTime()
println("hour: \(time.0)")

C is remarkable in this regard. One can say void is nothingness void* is everything (can be everything).

It's just this tiny * which makes the difference.

Rene has pointed it out. A void * is a Pointer to some location. What there is how to "interpret" is left to the user.

It's the only way to have opaque types in C. Very prominent examples can be found e.g in glib or general data structure libraries. It's treated very detailed in "C Interfaces and implementations".

I suggest you read the complete chapter and try to understand the concept of a pointer to "get it".

Building 4 edges solution basing on @Eagorajose's answer with shorthand syntax:

linear-gradient(#000 33%, #fff 0%) right/1px 10px repeat-y, /* right */
linear-gradient(to right, #000 33%, #fff 0%) bottom/10px 1px repeat-x, /* bottom */
linear-gradient(#000 33%, #fff 0%) left/1px 10px repeat-y; /* left */

    _x000D_
    width: 100px;_x000D_
    height: 100px;_x000D_
}

<div id="page"></div>

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

Here is my example:

<div class="form-group">
    <label for="contactMethod">Contact method</label>
    <select 
        name="contactMethod" 
        id="contactMethod" 
        class="form-control"
        [(ngModel)]="contact.contactMethod">
        <option *ngFor="let method of contactMethods" [value]="method.id">{{ method.label }}</option>
    </select>
</div>

And in component you must get values from select:

contactMethods = [
    { id: 1, label: "Email" },
    { id: 2, label: "Phone" }
]

So, if you want select to have a default value selected (and proabbly you want that):

contact = {
    firstName: "CFR",
    comment: "No comment",
    subscribe: true,
    contactMethod: 2 // this id you'll send and get from backend
}

Edit your phpmyadmin config.inc.php file and if you have Password, insert that in front of Password in following code:

$cfg['Servers'][$i]['verbose'] = 'localhost';
$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['port'] = '3306';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = '**your-root-username**';
$cfg['Servers'][$i]['password'] = '**root-password**';
$cfg['Servers'][$i]['AllowNoPassword'] = true;

Verifying that a user is an admin in javascript leads to trouble because javascript code is visible to anyone. The server is the one who should tell the difference between an admin and a regular user AFTER the login process and then generate the new page accordingly.

Maybe that's not what you are trying to do so to answer your question:

window.location.href="<the page you are going to>";

You may need to change the Appication Pool setting "Enable 32bit Applications" to TRUE in IIS7 if you have at least 1 32bit dll\exe in your project.

This is my favorite solution for SQL 2008 , which puts the results into a "TEST" temp table that I can use to sort and get the results that I need :

SET NOCOUNT ON 
DBCC UPDATEUSAGE(0) 
DROP TABLE #t;
CREATE TABLE #t 
( 
[name] NVARCHAR(128),
[rows] CHAR(11),
reserved VARCHAR(18), 
data VARCHAR(18), 
index_size VARCHAR(18),
unused VARCHAR(18)
) ;
INSERT #t EXEC sp_msForEachTable 'EXEC sp_spaceused ''?''' 
SELECT * INTO TEST FROM #t;
DROP TABLE #t;
SELECT  name, [rows], reserved, data, index_size, unused FROM TEST \
WHERE ([rows] > 0) AND (name LIKE 'XXX%')

Right click on Cell B1 and choose Format Cells. In Custom, put the following in the text box labeled Type:

[h]:mm:ss.000 

To set this in code, you can do something like:

Range("A1").NumberFormat = "[h]:mm:ss.000"

That should give you what you're looking for.

NOTE: Specially formatted fields often require that the column width be wide enough for the entire contents of the formatted text. Otherwise, the text will display as ######.

Just use:

<?php
    include("/path/to/file.html");
?>

That will echo it as well. This also has the benefit of executing any PHP in the file.

If you need to do anything with the contents, use file_get_contents(),

For example,

<?php
    $pagecontents = file_get_contents("/path/to/file.html");

    echo str_replace("Banana", "Pineapple", $pagecontents);

?>

This doesn't execute code in that file, so be careful if you expect that to work.

I usually use:

include($_SERVER['DOCUMENT_ROOT']."/path/to/file/as/in/url.html");

as then I can move files without breaking the includes.

Make sure you remove the .git repository if you are trying to check thing out into the current directory.

rm -rf .git then git clone https://github.com/symfony/symfony-sandbox.git

Javascript passes variables by reference, this means that:

var i = [];
var j = i;
i.push( 1 );

Now because of by reference part i is [1], and j is [1] as well, even though only i was changed. This is because when we say j = i javascript doesn't copy the i variable and assign it to j but references i variable through j.

Angular copy lets us lose this reference, which means:

var i = [];
var j = angular.copy( i );
i.push( 1 );

Now i here equals to [1], while j still equals to [].

There are situations when such kind of copy functionality is very handy.

Only MyISAM allows for FULLTEXT, as seen here.

Try this:

CREATE TABLE gamemech_chat (
  id bigint(20) unsigned NOT NULL auto_increment,
  from_userid varchar(50) NOT NULL default '0',
  to_userid varchar(50) NOT NULL default '0',
  text text NOT NULL,
  systemtext text NOT NULL,
  timestamp datetime NOT NULL default '0000-00-00 00:00:00',
  chatroom bigint(20) NOT NULL default '0',
  PRIMARY KEY  (id),
  KEY from_userid (from_userid),
  FULLTEXT KEY from_userid_2 (from_userid),
  KEY chatroom (chatroom),
  KEY timestamp (timestamp)
) ENGINE=MyISAM;

def function(arg)->123:

It's simply a return type, integer in this case doesn't matter which number you write.

like Java :

public int function(int args){...}

But for Python (how Jim Fasarakis Hilliard said) the return type it's just an hint, so it's suggest the return but allow anyway to return other type like a string..

even shorter if you can lose the yearStart value:

var yearStart = 2000;
var yearEnd = 2040;

var arr = [];

while(yearStart < yearEnd+1){
  arr.push(yearStart++);
}

UPDATE: If you can use the ES6 syntax you can do it the way proposed here:

let yearStart = 2000;
let yearEnd = 2040;
let years = Array(yearEnd-yearStart+1)
    .fill()
    .map(() => yearStart++);

For a 32-bit signed integer, such as System.Int32, aka int in C#:

bool isNegative = (num & (1 << 31)) != 0;

If You want to ensure, that your code is running with python2 and python3, use function input () in your script and add this to begin of your script:

from sys import version_info
if version_info.major == 3:
    pass
elif version_info.major == 2:
    try:
        input = raw_input
    except NameError:
        pass
else:
    print ("Unknown python version - input function not safe")

By default, Visual Studio searches for headers in the folder where your project is ($ProjectDir) and in the default standard libraries directories. If you need to include something that is not placed in your project directory, you need to add the path to the folder to include:

Go to your Project properties (Project -> Properties -> Configuration Properties -> C/C++ -> General) and in the field Additional Include Directories add the path to your .h file.

You can, also, as suggested by Chris Olen, add the path to VC++ Directories field.

I'm a little late to the game, but this may help others.

In my case my jenkins master has a shared external resource, which is allocated to jenkins jobs by the external-resource-dispatcher-plugin. Due to bug JENKINS-19439 in the plugin (which is in beta), I found that my resource had been locked by a previous job, but wasn't unlocked when that previous job was cancelled.

To find out if a resource is currently in the locked state, navigate to the affected jenkins node, Jenkins -> Manage Jenkins -> Manage Nodes -> master

You should see the current state of any external resources. If any are unexpectedly locked this may be the reason why jobs are waiting for an executor.

I couldn't find any details of how to manually resolve this issue.
Restarting jenkins didn't resolve the problem.
In the end I went with the brutal approach:

• Remove the external resource
  (see Jenkins -> Manage Jenkins -> Manage Nodes -> master -> configure)
• Restart jenkins
• Re-create the external resource

To concatenate strings, use the + operator.

To insert data into a URI, encode it for URIs.

Bad:

var url = "http://localhost:8080/login?cid='username'&pwd='password'"

Good:

var url_safe_username = encodeURIComponent(username);
var url_safe_password = encodeURIComponent(password);
var url = "http://localhost:8080/login?cid=" + url_safe_username + "&pwd=" + url_safe_password;

The server will have to process the query string to make use of the data. You can't assign to arbitrary form fields.

… but don't trigger new windows or pass credentials in the URI (where they are exposed to over the shoulder attacks and may be logged).

psql -U postgres

Worked fine for me in case of db name: postgres & username: postgres. So you do not need to write sudo.

And in the case other db, you may try

psql -U yourdb postgres

As it is given in Postgres help:

psql [OPTION]... [DBNAME [USERNAME]]

I know it has been quite sometime that you asked this but, if someone else needs, I did what was saying here " How to upload a project to Github " and after the top answer of this question right here. And after was the top answer was saying here "git error: failed to push some refs to" I don't know what exactly made everything work. But now is working.

here the problem is model binding if you specify a class then the model binding can understand it during the post if it an integer or string then you have to specify the [FromBody] to bind it properly.

make the following changes in FormMethod

using (@Html.BeginForm("myMethod", "Home", FormMethod.Post, new { id = @item.JobId })){

}

and inside your home controller for binding the string you should specify [FromBody]

using System.Web.Http;
[HttpPost]
public FileStreamResult myMethod([FromBody]string id)
{
     // Set a local variable with the incoming data
     string str = id;

}

FromBody is available in System.Web.Http. make sure you have the reference to that class and added it in the cs file.

Universal solution

You can get the favicon showing up in Django the same way you can do in any other framework: just use pure HTML.

Add the following code to the header of your HTML template.
Better, to your base HTML template if the favicon is the same across your application.

<link rel="shortcut icon" href="{% static 'favicon/favicon.png' %}"/>

The previous code assumes:

1. You have a folder named 'favicon' in your static folder
2. The favicon file has the name 'favicon.png'
3. You have properly set the setting variable STATIC_URL

You can find useful information about file format support and how to use favicons in this article of Wikipedia https://en.wikipedia.org/wiki/Favicon.
I can recommend use .png for universal browser compatibility.

EDIT:
As posted in one comment,
"Don't forget to add {% load staticfiles %} in top of your template file!"

To split the difference of opinion

   xls.DisplayAlerts = True

@user264892

I found that when using a String variable I needed to either prefix with an String of "" or explicitly cast to CharSequence.

So instead of:

String Status = "Asking Server...";
txtStatus.setText(Status);

try:

String Status = "Asking Server...";
txtStatus.setText((CharSequence) Status);

or:

String Status = "Asking Server...";    
txtStatus.setText("" + Status);

or, since your string is not dynamic, even better:

txtStatus.setText("AskingServer...");

Slight variation to the above answers, but with Vanilla JS:

var nav = document.querySelector('nav'); // Identify target

window.addEventListener('scroll', function(event) { // To listen for event
    event.preventDefault();

    if (window.scrollY <= 150) { // Just an example
        nav.style.backgroundColor = '#000'; // or default color
    } else {
        nav.style.backgroundColor = 'transparent';
    }
});

IPv6 localhost

::1 is the loopback address in IPv6.

Within URLs

Within a URL, use square brackets []:

• http://[::1]/
  Defaults to port 80.
• http://[::1]:80/
  Specify port.

Enclosing the IPv6 literal in square brackets for use in a URL is defined in RFC 2732 – Format for Literal IPv6 Addresses in URL's.

I noticed that you can also get errors if you don't specify the angles correctly, even when using glm::rotate(Model, angle_in_degrees, glm::vec3(x, y, z)) you still might run into problems. The fix I found for this was specifying the type as glm::rotate(Model, (glm::mediump_float)90, glm::vec3(x, y, z)) instead of just saying glm::rotate(Model, 90, glm::vec3(x, y, z))

Or just write the second argument, the angle in radians (previously in degrees), as a float with no cast needed such as in:

glm::mat4 rotationMatrix = glm::rotate(glm::mat4(1.0f), 3.14f, glm::vec3(1.0));

You can add glm::radians() if you want to keep using degrees. And add the includes:

#include "glm/glm.hpp"
#include "glm/gtc/matrix_transform.hpp"

A short summary from my humble knowledge:

There are some easy computational problems (like finding the shortest path between two points in a graph), which can be calculated pretty fast ( O(n^k), where n is the size of the input and k is a constant (in the case of graphs, it's the number of vertexes or edges)).

Other problems, like finding a path that crosses every vertex in a graph or getting the RSA private key from the public key is harder (O(e^n)).

But CS speak tells that the problem is that we cannot 'convert' a non-deterministic Turing-machine to a deterministic one, we can, however, transform non-deterministic finite automatons (like the regex parser) into deterministic ones (well, you can, but the run-time of the machine will take long). That is, we have to try every possible path (usually smart CS professors can exclude a few ones).

It's interesting because nobody even has any idea of the solution. Some say it's true, some say it's false, but there is no consensus. Another interesting thing is that a solution would be harmful for public/private key encryptions (like RSA). You could break them as easily as generating an RSA key is now.

And it's a pretty inspiring problem.

In my computer there wasn't a uninstaller in the Start Menu as well. But it worked it the Control Panel > Programs > Uninstall a Program, and selecting Python(Anaconda64bits) in the menu. (Note that I'm using Win10)

For me

sudo apt-get install php5-mcrypt 

solved the issue

Refining upon the answers found here I came up with the following:

getCurrentScript.js

var getCurrentScript = function () {
  if (document.currentScript) {
    return document.currentScript.src;
  } else {
    var scripts = document.getElementsByTagName('script');
    return scripts[scripts.length-1].src;

  }
};

module.exports = getCurrentScript;

getCurrentScriptPath.js

var getCurrentScript = require('./getCurrentScript');

var getCurrentScriptPath = function () {
  var script = getCurrentScript();
  var path = script.substring(0, script.lastIndexOf('/'));
  return path;
};

module.exports = getCurrentScriptPath;

BTW: I'm using CommonJS module format and bundling with webpack.

If you're using HTTPS, check to make sure that your URL is correct. For example:

$ git clone https://github.com/wellle/targets.git
Cloning into 'targets'...
Username for 'https://github.com': ^C

$ git clone https://github.com/wellle/targets.vim.git

You can use em, %, px. But in combination with media-queries See this Link to learn about media-queries. Also, CSS3 have some new values for sizing things relative to the current viewport size: vw, vh, and vmin. See link about that.

Within the range 0 = c < 128, yes the ' is the only difference for CPython 2.6.

>>> set(unichr(c).encode('unicode_escape') for c in range(128)) - set(chr(c).encode('string_escape') for c in range(128))
set(["'"])

Outside of this range the two types are not exchangeable.

On Python 3.x, the string_escape encoding no longer exists, since str can only store Unicode.

When you have a lot of insertion or deletion in the middle of the sequence. e.g. a memory manager.

Your modifications are in a different branch than the original branch, which simplifies stuff because you get updates in one branch, and your work is in another branch.

Assuming the original branch is named master, which the case in 99% of git repos, you have to fetch the state of origin, and merge origin/master updates into your local master:

 git fetch origin
 git checkout master
 git merge origin/master

To switch to your branch, just do

 git checkout branch1

(Updated for Spring 3.0)

I go with Spring MVC as well.

You need to download Spring from here

To configure your web-app to use Spring add the following servlet to your web.xml

<web-app>
    <servlet>
        <servlet-name>spring-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>spring-dispatcher</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

You then need to create your Spring config file /WEB-INF/spring-dispatcher-servlet.xml

Your first version of this file can be as simple as:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="
        http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/mvc     http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

   <context:component-scan base-package="com.acme.foo" />    
   <mvc:annotation-driven />

</beans>

Spring will then automatically detect classes annotated with @Controller

A simple controller is then:

package com.acme.foo;

import java.util.logging.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping("/person")
public class PersonController {

    Logger logger = Logger.getAnonymousLogger();

    @RequestMapping(method = RequestMethod.GET)
    public String setupForm(ModelMap model) {
        model.addAttribute("person", new Person());
        return "details.jsp";
    }

    @RequestMapping(method = RequestMethod.POST)
    public String processForm(@ModelAttribute("person") Person person) {
        logger.info(person.getId());
        logger.info(person.getName());
        logger.info(person.getSurname());
        return "success.jsp";
   }
}

And the details.jsp

<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<form:form commandName="person">
<table>
    <tr>
        <td>Id:</td>
        <td><form:input path="id" /></td>
    </tr>
    <tr>
        <td>Name:</td>
        <td><form:input path="name" /></td>
    </tr>
    <tr>
        <td>Surname:</td>
        <td><form:input path="surname" /></td>
    </tr>
    <tr>
        <td colspan="2"><input type="submit" value="Save Changes" /></td>
    </tr>
</table>
</form:form>

This is just the tip of the iceberg with regards to what Spring can do...

Hope this helps.

Based on this code (which you provided in response to Alex's answer):

Editable newTxt=(Editable)userName1.getText(); 
String newString = newTxt.toString();

It looks like you're trying to get the text out of a TextView or EditText. If that's the case then this should work:

String newString = userName1.getText().toString(); 

This code is IE only so it is only useful in situations where you know all of your users will be using IE (like, for example, in some corporate environments.)

<script Language="javascript">
function ExportHTMLTableToExcel()
{
   var thisTable = document.getElementById("tbl").innerHTML;
   window.clipboardData.setData("Text", thisTable);
   var objExcel = new ActiveXObject ("Excel.Application");
   objExcel.visible = true;

   var objWorkbook = objExcel.Workbooks.Add;
   var objWorksheet = objWorkbook.Worksheets(1);
   objWorksheet.Paste;
}
</script>

This worked for me:

// Change default JQuery validation Messages.
$("#addnewcadidateform").validate({
        rules: {
            firstname: "required",
            lastname: "required",
            email: "required email",
        },
        messages: {
            firstname: "Enter your First Name",
            lastname: "Enter your Last Name",
            email: {
                required: "Enter your Email",
                email: "Please enter a valid email address.",
            }
        }
    })

For example you have a start program named run.sh to start it working at background do the following command line. ./run.sh &>/dev/null &

Open phpmyadmin, go to database and corresponding table to find it out.

The IN was too slow in my situation (180 secs)

So I used a JOIN instead (0.3 secs)

SELECT i.id, i.payer_email
FROM paypal_ipn_orders i
INNER JOIN (
 SELECT payer_email
    FROM paypal_ipn_orders 
    GROUP BY payer_email
    HAVING COUNT( id ) > 1
) j ON i.payer_email=j.payer_email

You have another server_name ec2-xx-xx-xxx-xxx.us-west-1.compute.amazonaws.com somewhere in the config.

You must do something like this

SELECT onDay, id, 
sum(pxLow)/count(*),sum(pxLow),count(`*`),
CONCAT(YEAR(onDay),"-",MONTH(onDay)) as sdate 
FROM ... where stockParent_id =16120 group by sdate order by onDay

Just note to anyone trying the REGEXP to use "LIKE IN" functionality.

IN allows you to do:

field IN (
'val1',
'val2',
'val3'
)

In REGEXP this won't work

REGEXP '
val1$|
val2$|
val3$
'

It has to be in one line like this:

REGEXP 'val1$|val2$|val3$'

Don't forget that you can not cross domains because of security.

So if this is the case, you should use JSON.

In iOS 9.1 and lower, go to Settings - General - Profiles - tap on your Profile - tap on Trust button.

In iOS 9.2+ & iOS 11+ go to: Settings - General - Profiles & Device Management - tap on your Profile - tap on Trust button.

In iOS 10+, go to: Settings - General - Device Management - tap on your Profile - tap on Trust button.

1 You can use a drawable

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_item1"
        android:icon="@drawable/my_item_drawable"
        android:title="@string/menu_item1"
        android:showAsAction="ifRoom" />
</menu>

2 Create a style for the action bar and use a custom background:

<resources>
    <!-- the theme applied to the application or activity -->
    <style name="CustomActivityTheme" parent="@android:style/Theme.Holo">
        <item name="android:actionBarStyle">@style/MyActionBar</item>
        <!-- other activity and action bar styles here -->
    </style>
    <!-- style for the action bar backgrounds -->
    <style name="MyActionBar" parent="@android:style/Widget.Holo.ActionBar">
        <item name="android:background">@drawable/background</item>
        <item name="android:backgroundStacked">@drawable/background</item>
        <item name="android:backgroundSplit">@drawable/split_background</item>
    </style>
</resources>

3 Style again android:actionBarDivider

The android documentation is very usefull for that.

Since this came up on a Google search for "javascript get number of digits", I wanted to throw it out there that there is a shorter alternative to this that relies on internal casting to be done for you:

var int_number = 254;
var int_length = (''+int_number).length;

var dec_number = 2.12;
var dec_length = (''+dec_number).length;

console.log(int_length, dec_length);

Yields

3 4

You can do git push --force but be aware that you are rewriting history and anyone using the repo will have issue with this.

If you want to prevent this problem, don't use reset, but instead use git revert

I tried my best to follow the answers given above. But I have below reason for the same.

Note: This is for maven+eclipse+tomcat deployment and issue faced especially with spring mvc.

1- If you are including servlet and jsp dependency please mark them provided in scope.

<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>javax.servlet.jsp-api</artifactId>
        <version>2.3.1</version>
        <scope>provided</scope>
    </dependency>

2. Possibly you might be including jstl as dependency. So, jsp-api.jar and servlet-api.jar will be included along. So, require to exclude the servlet-api and jsp-api being deployed as required lib in target or in "WEB-INF/lib" as given below.

   <dependency>
       <groupId>javax.servlet.jsp.jstl</groupId>
       <artifactId>jstl-api</artifactId>

Fragment's onSaveInstanceState(Bundle outState) will never be called unless fragment's activity call it on itself and attached fragments. Thus this method won't be called until something (typically rotation) force activity to SaveInstanceState and restore it later. But if you have only one activity and large set of fragments inside it (with intensive usage of replace) and application runs only in one orientation activity's onSaveInstanceState(Bundle outState) may not be called for a long time.

I know three possible workarounds.

The first:

use fragment's arguments to hold important data:

public class FragmentA extends Fragment {
    private static final String PERSISTENT_VARIABLE_BUNDLE_KEY = "persistentVariable";

    private EditText persistentVariableEdit;

    public FragmentA() {
        setArguments(new Bundle());
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_a, null);

        persistentVariableEdit = (EditText) view.findViewById(R.id.editText);

        TextView proofTextView = (TextView) view.findViewById(R.id.textView);

        Bundle mySavedInstanceState = getArguments();
        String persistentVariable = mySavedInstanceState.getString(PERSISTENT_VARIABLE_BUNDLE_KEY);

        proofTextView.setText(persistentVariable);


        view.findViewById(R.id.btnPushFragmentB).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                getFragmentManager()
                        .beginTransaction()
                        .replace(R.id.frameLayout, new FragmentB())
                        .addToBackStack(null)
                        .commit();
            }
        });

        return view;
    }

    @Override
    public void onPause() {
        super.onPause();
        String persistentVariable = persistentVariableEdit.getText().toString();

        getArguments().putString(PERSISTENT_VARIABLE_BUNDLE_KEY, persistentVariable);
    }
}

The second but less pedantic way - hold variables in singletons

The third - don't replace() fragments but add()/show()/hide() them instead.

Andreas' answer above was helpful in solving my problem of how to test artisan on port 80. Port 80 can be specified like the other port numbers, but regular users do not have permissions to run anything on that port.

Drop a little common sense on there and you end up with this for Linux:

sudo php artisan serve --port=80

This will allow you to test on localhost without specifying the port in your browser. You can also use this to set up a temporary demo, as I have done.

Keep in mind, however, that PHP's built in server is not designed for production. Use nginx/Apache for production.

The problem here is that I don't know what is expected. With your current setup, invoking the plugin on the command line would just work:

$ mvn exec:exec
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[INFO] Building Q3491937
[INFO]    task-segment: [exec:exec]
[INFO] ------------------------------------------------------------------------
[INFO] [exec:exec {execution: default-cli}]
[INFO] laptop
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] ------------------------------------------------------------------------
...

The global configuration is used, the hostname command is executed (laptop is my hostname). In other words, the plugin works as expected.

Now, if you want a plugin to get executed as part of the build, you have to bind a goal on a specific phase. For example, to bind it on compile:

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.1.1</version>
    <executions>
      <execution>
        <id>some-execution</id>
        <phase>compile</phase>
        <goals>
          <goal>exec</goal>
        </goals>
      </execution>
    </executions>
    <configuration>
      <executable>hostname</executable>
    </configuration>
  </plugin>

And then:

$ mvn compile
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[INFO] Building Q3491937
[INFO]    task-segment: [compile]
[INFO] ------------------------------------------------------------------------
[INFO] [resources:resources {execution: default-resources}]
[INFO] Using 'UTF-8' encoding to copy filtered resources.
[INFO] skip non existing resourceDirectory /home/pascal/Projects/Q3491937/src/main/resources
[INFO] [compiler:compile {execution: default-compile}]
[INFO] Nothing to compile - all classes are up to date
[INFO] [exec:exec {execution: some-execution}]
[INFO] laptop
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] ------------------------------------------------------------------------
...

Note that you can specify a configuration inside an execution.

If your main objective is doing math, SymPy provides an excellent approach to functional latex expressions that look great.

Under the Tools menu in Visual Studio 2008 (or 2005 if you have the right WCF stuff installed) there is an options called 'WCF Service Configuration Editor'.

From there you can change the binding options for both the client and the services, one of these options will be for time-outs.

No. Unfortunately the Request object is only available until the page finishes loading - once it's complete, you'll lose all values in it unless they've been stored somewhere.

If you want to persist attributes through requests you need to either:

1. Have a hidden input in your form, such as <input type="hidden" name="myhiddenvalue" value="<%= request.getParameter("value") %>" />. This will then be available in the servlet as a request parameter.
2. Put it in the session (see request.getSession() - in a JSP this is available as simply session)

I recommend using the Session as it's easier to manage.

It's because you aren't giving the un-hovered state a right attribute.

right isn't set so it's trying to go from nothing to 0px. Obviously because it has nothing to go to, it just 'warps' over.

If you give the unhovered state a right:90%;, it will transition how you like.

Just as a side note, if you still want it to be on the very left of the page, you can use the calc css function.

Example:

right: calc(100% - 100px)
                     ^ width of div

You don't have to use left then.

Also, you can't transition using left or right auto and will give the same 'warp' effect.

div {_x000D_
    width:100px;_x000D_
    height:100px;_x000D_
    background:red;_x000D_
    transition:2s;_x000D_
    -webkit-transition:2s;_x000D_
    -moz-transition:2s;_x000D_
    position:absolute;_x000D_
    right:calc(100% - 100px);_x000D_
}_x000D_
div:hover {_x000D_
  right:0;_x000D_
}

<p>_x000D_
  <b>Note:</b> This example does not work in Internet Explorer 9 and earlier versions._x000D_
</p>_x000D_
<div></div>_x000D_
<p>Hover over the red square to see the transition effect.</p>

CanIUse says that the calc() function only works on IE10+

1. Check the trees.config file which located in config folder... sometimes (I don't know why) this file became to be empty like someone delete the content inside... keep backup up of this file in your local pc then when this error appear - replace the server file with your local file. This is what i do when this error happened.

2. check the available space on the server. sometimes this is the problem.

Good luck.

There will not be any harm deleting the forked repositories. You can again fork that. It won't change the original code. The flow is like this...

1) You fork a repository. Just think of this as another copy of code which you can access or make changes to. The url of this repository will be of the form https://github.com/your-user-name/original-repo.

2) You make some changes to that in your local machine and push them. Now the copy you created will be updated, but not the original one from which you have forked your repo.

3) If you want the changes you added to your forked repo to be applied to original repo(this may be helpful to the people who are organizing the repo) then you have to create a pull request which you can do through UI. Then if they like your contribution, they will merge that with their code.

Generally this is what open source organizations do.

I found the answer:

$mail->AddEmbeddedImage('img/2u_cs_mini.jpg', 'logo_2u');

and on the <img> tag put src='cid:logo_2u'

Use OutputDebugString instead of afxDump.

Example:

#define _TRACE_MAXLEN 500

#if _MSC_VER >= 1900
#define _PRINT_DEBUG_STRING(text) OutputDebugString(text)
#else // _MSC_VER >= 1900
#define _PRINT_DEBUG_STRING(text) afxDump << text
#endif // _MSC_VER >= 1900

void MyTrace(LPCTSTR sFormat, ...)
{
    TCHAR text[_TRACE_MAXLEN + 1];
    memset(text, 0, _TRACE_MAXLEN + 1);
    va_list args;
    va_start(args, sFormat);
    int n = _vsntprintf(text, _TRACE_MAXLEN, sFormat, args);
    va_end(args);
    _PRINT_DEBUG_STRING(text);
    if(n <= 0)
        _PRINT_DEBUG_STRING(_T("[...]"));
}

That is because you are trying to access the plugin before it's loaded. You should try making a call to it when the DOM is loaded by surrounding it with this:

$(document).ready(function(){
    $("#colorpicker").colorpicker();
}

numpy.array is a function that returns a numpy.ndarray. There is no object type numpy.array.

No. This needs to be done in the HTML. You could set the value with Javascript if you need to though.

Code Formatting Shortcut:

VSCode on Windows - Shift + Alt + F

VSCode on MacOS - Shift + Option + F

VSCode on Ubuntu - Ctrl + Shift + I

You can also customize this shortcut using preference setting if needed.

In addition to answer of @jww, I would like to say that the configuration in openssl-ca.cnf,

default_days     = 1000         # How long to certify for

defines the default number of days the certificate signed by this root-ca will be valid. To set the validity of root-ca itself you should use '-days n' option in:

openssl req -x509 -days 3000 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM

Failing to do so, your root-ca will be valid for only the default one month and any certificate signed by this root CA will also have validity of one month.

And,

If your IN clause is too big for MSSQL to handle, you can use a TableValueParameter with Dapper pretty easily.

1. Create your TVP type in MSSQL:

   CREATE TYPE [dbo].[MyTVP] AS TABLE([ProviderId] [int] NOT NULL)
   

2. Create a DataTable with the same column(s) as the TVP and populate it with values

   var tvpTable = new DataTable();
   tvpTable.Columns.Add(new DataColumn("ProviderId", typeof(int)));
   // fill the data table however you wish
   

3. Modify your Dapper query to do an INNER JOIN on the TVP table:

   var query = @"SELECT * FROM Providers P
       INNER JOIN @tvp t ON p.ProviderId = t.ProviderId";
   

4. Pass the DataTable in your Dapper query call

   sqlConn.Query(query, new {tvp = tvpTable.AsTableValuedParameter("dbo.MyTVP")});
   

This also works fantastically when you want to do a mass update of multiple columns - simply build a TVP and do an UPDATE with an inner join to the TVP.

Unfortunately the above solutions did not work in my case - maybe because a put the button inside a form-tag. This code ...

<input class="button" type="submit" value=" ">
    <img src="../assets/logo.png" alt="test" />
</input>

... always leads to error (with or without the closing slash of the img tag):

error  Parsing error: x-invalid-end-tag  vue/no-parsing-error

? 1 problem (1 error, 0 warnings)

A kind of workaround that did work was to define the image as background-image by means of css.

The html snippet describes the button only. The value attribute contains a single blank in order to suppress some browsers presenting unwanted default text.

<input class="button" type="submit" value=" " />

the CSS defines the button's background image:

.button {
  display: block;
  width: 6em;
  height: 6em;
  color: white;
  background-color: #639f59;

The value attribute on submit-type <input> elements controls the text displayed.

<input type="submit" class="like" value="Like" />

If you want to change one specific onclick event with jQuery, you better use the functions .on() and .off() with a namespace (see documentation).

Use .on() to create your event and .off() to remove it. You can also create a global object like g_specific_events_set = {}; to avoid duplicates:

$('#alert').click(function()_x000D_
{_x000D_
    alert('First alert!');_x000D_
});_x000D_
_x000D_
g_specific_events_set = {};_x000D_
_x000D_
add_specific_event = function(namespace)_x000D_
{_x000D_
    if (!g_specific_events_set[namespace])_x000D_
    {_x000D_
        $('#alert').on('click.' + namespace, function()_x000D_
        {_x000D_
            alert('SECOND ALERT!!!!!!');_x000D_
        });_x000D_
        g_specific_events_set[namespace] = true;_x000D_
    }_x000D_

_x000D_
remove_specific_event = function(namespace)_x000D_

    g_specific_events_set[namespace] = false;_x000D_

_x000D_
_x000D_

Actually we can not create an object of an abstract class directly. What we create is a reference variable of an abstract call. The reference variable is used to Refer to the object of the class which inherits the Abstract class i.e. the subclass of the abstract class.

Just make sure the python executable is in your PATH environment variable then add in your script

python path/to/the/python_script.py

Details:

• In the file job.sh, put this

#!/bin/sh
python python_script.py

• Execute this command to make the script runnable for you : chmod u+x job.sh
• Run it : ./job.sh

Did you mean like this for textfield?

<input type="text" onblur="if(this.value == '') this.value='SEARCH';" onfocus="if(this.value == 'SEARCH') this.value='';" size="15" value="SEARCH" name="xSearch" id="xSearch">

Or this for textarea?

<textarea id="usermsg" rows="2" cols="70" onfocus="if(this.value == 'enter your text here') this.value='';" onblur="if(this.value == '') this.value='enter your text here';" >enter your text here</textarea>

The => operator is used to assign key-value pairs in an associative array. For example:

$fruits = array(
  'Apple'  => 'Red',
  'Banana' => 'Yellow'
);

It's meaning is similar in the foreach statement:

foreach ($fruits as $fruit => $color)
  echo "$fruit is $color in color.";

Round numbers, yes. This is the main example source.

For those of you who would rather not go with Regex and are on the .NET 2.0 Framework (AKA no LINQ):

Only Letters:

public static bool IsAllLetters(string s)
{
    foreach (char c in s)
    {
        if (!Char.IsLetter(c))
            return false;
    }
    return true;
}

Only Numbers:

    public static bool IsAllDigits(string s)
    {
        foreach (char c in s)
        {
            if (!Char.IsDigit(c))
                return false;
        }
        return true;
    }

Only Numbers Or Letters:

    public static bool IsAllLettersOrDigits(string s)
    {
        foreach (char c in s)
        {
            if (!Char.IsLetterOrDigit(c))
                return false;
        }
        return true;
    }

Only Numbers Or Letters Or Underscores:

    public static bool IsAllLettersOrDigitsOrUnderscores(string s)
    {
        foreach (char c in s)
        {
            if (!Char.IsLetterOrDigit(c) && c != '_')
                return false;
        }
        return true;
    }

I use (a very old) process explorer from SysInternals (procexp.exe). It is a replacement / addition to the standard Task manager, you can suspend a process from there.

Edit: Microsoft has bought over SysInternals, url: procExp.exe

Other than that you can set the process priority to low so that it does not get in the way of other processes, but this will not suspend the process.

You can implement a class that holds the fields you have in your JSON

class MyData
{
    public string t;
    public bool a;
    public object[] data;
    public string[][] type;
}

and then use the generic version of DeserializeObject:

MyData tmp = JsonConvert.DeserializeObject<MyData>(json);
foreach (string typeStr in tmp.type[0])
{
    // Do something with typeStr
}

Documentation: Serializing and Deserializing JSON

Another way to solve this:-

var res = [{"s1":5},{"s2":3},{"s3":8}].sort(function(obj1,obj2){ 
 var prop1;
 var prop2;
 for(prop in obj1) {
  prop1=prop;
 }
 for(prop in obj2) {
  prop2=prop;
 }
 //the above two for loops will iterate only once because we use it to find the key
 return obj1[prop1]-obj2[prop2];
});

//res will have the result array

I'm adding an up-to-date answer here, given recent developments.

You can forward-declare an enum in C++11, so long as you declare its storage type at the same time. The syntax looks like this:

enum E : short;
void foo(E e);

....

enum E : short
{
    VALUE_1,
    VALUE_2,
    ....
}

In fact, if the function never refers to the values of the enumeration, you don't need the complete declaration at all at that point.

This is supported by G++ 4.6 and onwards (-std=c++0x or -std=c++11 in more recent versions). Visual C++ 2013 supports this; in earlier versions it has some sort of non-standard support that I haven't figured out yet - I found some suggestion that a simple forward declaration is legal, but YMMV.

Here this should help you

The below jsfiddle link will help you understand how to rotate a image.I used the same one to rotate the dial of a clock.

http://jsfiddle.net/xw89p/

var rotation = function (){
   $("#image").rotate({
      angle:0, 
      animateTo:360, 
      callback: rotation,
      easing: function (x,t,b,c,d){       
          return c*(t/d)+b;
      }
   });
}
rotation();

Where: • t: current time,

• b: begInnIng value,

• c: change In value,

• d: duration,

• x: unused

No easing (linear easing): function(x, t, b, c, d) { return b+(t/d)*c ; }

Supposing you're using plain JS (see other answers for jQuery), to change an element's opacity, write:

var element = document.getElementById('id');
element.style.opacity = "0.9";
element.style.filter  = 'alpha(opacity=90)'; // IE fallback

Both array_push and the method you described will work.

$customArray = array();
$customArray[] = 20;
$customArray[] = 21;

Above is correct, but below one is for further understanding

$customArray = array();
for($i=0;$i<=12;$i++){
    $cart[] = $i;  
}
echo "<pre>";
print_r($customArray);
echo "</pre>";

Regarding [NSException raise:format:]. For those coming from a Java background, you will recall that Java distinguishes between Exception and RuntimeException. Exception is a checked exception, and RuntimeException is unchecked. In particular, Java suggests using checked exceptions for "normal error conditions" and unchecked exceptions for "runtime errors caused by a programmer error." It seems that Objective-C exceptions should be used in the same places you would use an unchecked exception, and error code return values or NSError values are preferred in places where you would use a checked exception.

I agree with Darko Z on applying "overflow: hidden" to #sub-title. However, it should be mentioned that the overflow:hidden method of clearing floats does not work with IE6 unless you have a specified width or height. Or, if you don't want to specify a width or height, you can use "zoom: 1":

#sub-title { overflow:hidden; zoom: 1; }

How about this?

import fileinput
import sys

counter=0
for line in fileinput.input([sys.argv[1]]):
    counter+=1

fileinput.close()
print counter

Does your find have the -mmin option? That can let you test the number of mins since last modification:

find $LOCATION -name $REQUIRED_FILES -type f -mmin +360 -delete

Or maybe look at using tmpwatch to do the same job. phjr also recommended tmpreaper in the comments.

In Windows Forms, if your string is in a textbox, you can easily use this:

textBoxcsharp.SelectAll();
textBoxcsharp.Copy();
textBoxcsharp.DeselectAll();

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

if you want to get the first N elements and also remove it from the array, you can use array_splice() (note the 'p' in "splice"):

http://docs.php.net/manual/da/function.array-splice.php

use it like so: $array_without_n_elements = array_splice($old_array, 0, N)

Your Fragment can subclass ListFragment.
And onCreateView() from ListFragment will return a ListView you can then populate.

This feature shud have come built in Ios, however we need to do externally.
Insert the below code
* To move view when textField is under keyboard,
* Not to move view when textField is above keyboard
* To move View based on the height of the keyboard when needed.
This works and tested in all cases.

|::| Sometimes View wil be down, In that case use height +/- 150 :

    NonKeyPadAraVar.size.height -= self.KeyPadHytVal + 150

    { self.view.frame.origin.y -= self.KeyPadHytVal  - 150},

    { self.view.frame.origin.y += self.KeyPadHytVal  - 150},
                completion: nil)

If anyone is looking for a quick fix for this, here's how you do it.

while (array[i] != '\0') i++;

The variable i will hold the used length of the array, not the entire initialized array. I know it's a late post, but it may help someone.

Similar to yebmouxing I could not the

 xhr.getResponseHeader('Set-Cookie');

method to work. It would only return null even if I had set HTTPOnly to false on my server.

I too wrote a simple js helper function to grab the cookies from the document. This function is very basic and only works if you know the additional info (lifespan, domain, path, etc. etc.) to add yourself:

function getCookie(cookieName){
  var cookieArray = document.cookie.split(';');
  for(var i=0; i<cookieArray.length; i++){
    var cookie = cookieArray[i];
    while (cookie.charAt(0)==' '){
      cookie = cookie.substring(1);
    }
    cookieHalves = cookie.split('=');
    if(cookieHalves[0]== cookieName){
      return cookieHalves[1];
    }
  }
  return "";
}

R doesn't have these operations because (most) objects in R are immutable. They do not change. Typically, when it looks like you're modifying an object, you're actually modifying a copy.

It depends on the jQuery selector that you use. Since id should be unique within the DOM, the first one would be simple:

$('#Comanda').hide();

The second one might require something more, depending on the other elements and how to uniquely identify it. If the name of that particular input is unique, then this would work:

$('input[name="Vizualizeaza"]').hide();

In Hadoop 2.0,

hdfs dfs -copyToLocal <hdfs_input_file_path> <output_path>

where,

• hdfs_input_file_path maybe obtained from http://<<name_node_ip>>:50070/explorer.html

• output_path is the local path of the file, where the file is to be copied to.

• you may also use get in place of copyToLocal.

Steps to fix:

1. Run flutter clean in terminal.

2. Run your app again.

$(document).ready(function() {
    $('#Button').click(function() {
        $(this).addClass('active');
    });
});

should do the trick. unless you're loading the button with ajax. In which case you could do:

$('#Button').live('click', function() {...

Also remember not to use the same id more than once in your html code.

If the array is statically allocated, use sizeof(array) / sizeof(array[0])

If it's dynamically allocated, though, unfortunately you're out of luck as this trick will always return sizeof(pointer_type)/sizeof(array[0]) (which will be 4 on a 32 bit system with char*s) You could either a) keep a #define (or const) constant, or b) keep a variable, however.

The solution depends on the answer to the question - are all the parameters going to be the same type and if so will each be treated the same?

If the parameters are not the same type or more importantly are not going to be treated the same then you should use method overloading:

public class MyClass
{
  public void doSomething(int i) 
  {
    ...
  }

  public void doSomething(int i, String s) 
  {
    ...
  }

  public void doSomething(int i, String s, boolean b) 
  {
    ...
  }
}

If however each parameter is the same type and will be treated in the same way then you can use the variable args feature in Java:

public MyClass 
{
  public void doSomething(int... integers)
  {
    for (int i : integers) 
    {
      ...
    }
  }
}

Obviously when using variable args you can access each arg by its index but I would advise against this as in most cases it hints at a problem in your design. Likewise, if you find yourself doing type checks as you iterate over the arguments then your design needs a review.

Sun's JVM needs contiguous memory. So the maximal amount of available memory is dictated by memory fragmentation. Especially driver's dlls tend to fragment the memory, when loading into some predefined base address. So your hardware and its drivers determine how much memory you can get.

Two sources for this with statements from Sun engineers: forum blog

Maybe another JVM? Have you tried Harmony? I think they planned to allow non-continuous memory.

I wrote a simple wrapper called KRNSendEmail that simplify sending email to one method call.

Regarding the question,

” can someone explain why the compare() function exists if a comparison can be made using simple operands?

Relative to < and ==, the compare function is conceptually simpler and in practice it can be more efficient since it avoids two comparisons per item for ordinary ordering of items.

As an example of simplicity, for small integer values you can write a compare function like this:

auto compare( int a, int b ) -> int { return a - b; }

which is highly efficient.

Now for a structure

struct Foo
{
    int a;
    int b;
    int c;
};

auto compare( Foo const& x, Foo const& y )
    -> int
{
    if( int const r = compare( x.a, y.a ) ) { return r; }
    if( int const r = compare( x.b, y.b ) ) { return r; }
    return compare( x.c, y.c );
}

Trying to express this lexicographic compare directly in terms of < you wind up with horrendous complexity and inefficiency, relatively speaking.

With C++11, for the simplicity alone ordinary less-than comparison based lexicographic compare can be very simply implemented in terms of tuple comparison.

You can MongoDB aggregation to do the task:

db.collection.aggregate([
  {
    $addFields: {
      arrayLength: {$size: '$array'}
    },
  },
  {
    $match: {
      arrayLength: {$gt: 1}
    },
  },
])

Bit of a resurrect but for anyone else coming to this question, take a look at the Micro editor. It's a small standalone EXE with no dependencies and with native Windows 32\64 versions. Works well in both PowerShell and CMD.EXE.

Is the standard procedure not working?

• make changes
• git stash save
• git branch xxx HEAD
• git checkout xxx
• git stash pop

Shorter:

• make changes
• git stash
• git checkout -b xxx
• git stash pop

You could do something with APIs.

Here are three ways to parse strings into integers, from fastest runtime to slowest:

1. strconv.ParseInt(...) fastest
2. strconv.Atoi(...) still very fast
3. fmt.Sscanf(...) not terribly fast but most flexible

Here's a benchmark that shows usage and example timing for each function:

package main

import "fmt"
import "strconv"
import "testing"

var num = 123456
var numstr = "123456"

func BenchmarkStrconvParseInt(b *testing.B) {
  num64 := int64(num)
  for i := 0; i < b.N; i++ {
    x, err := strconv.ParseInt(numstr, 10, 64)
    if x != num64 || err != nil {
      b.Error(err)
    }
  }
}

func BenchmarkAtoi(b *testing.B) {
  for i := 0; i < b.N; i++ {
    x, err := strconv.Atoi(numstr)
    if x != num || err != nil {
      b.Error(err)
    }
  }
}

func BenchmarkFmtSscan(b *testing.B) {
  for i := 0; i < b.N; i++ {
    var x int
    n, err := fmt.Sscanf(numstr, "%d", &x)
    if n != 1 || x != num || err != nil {
      b.Error(err)
    }
  }
}

You can run it by saving as atoi_test.go and running go test -bench=. atoi_test.go.

Before Java 8 (versions 7 or 6) I use the new method ArgumentMatchers.anyList:

import static org.mockito.Mockito.*;
import org.mockito.ArgumentMatchers;

verify(mock, atLeastOnce()).process(ArgumentMatchers.<Bar>anyList());

you have to use this code:

with <%@ taglib prefix="c" uri="http://www.springframework.org/tags/form"%>

and

<c:select>
            <option value="RCV"
                ${records[0].getDirection() == 'RCV' ? 'selected="true"' : ''}>
                <spring:message code="dropdown.Incoming" text="dropdown.Incoming" />
            </option>
            <option value="SND"
                ${records[0].getDirection() == 'SND'? 'selected="true"' : ''}>

The easiest way would probably be to convert the array into a java.util.ArrayList. Once it is in an arraylist, you can easily leverage the contains method.

public static boolean bagOfWords(String str)
{
    String[] words = {"word1", "word2", "word3", "word4", "word5"};  
    return (Arrays.asList(words).contains(str));
}

public static void copyFolder(File source, File destination)
{
    if (source.isDirectory())
    {
        if (!destination.exists())
        {
            destination.mkdirs();
        }

        String files[] = source.list();

        for (String file : files)
        {
            File srcFile = new File(source, file);
            File destFile = new File(destination, file);

            copyFolder(srcFile, destFile);
        }
    }
    else
    {
        InputStream in = null;
        OutputStream out = null;

        try
        {
            in = new FileInputStream(source);
            out = new FileOutputStream(destination);

            byte[] buffer = new byte[1024];

            int length;
            while ((length = in.read(buffer)) > 0)
            {
                out.write(buffer, 0, length);
            }
        }
        catch (Exception e)
        {
            try
            {
                in.close();
            }
            catch (IOException e1)
            {
                e1.printStackTrace();
            }

            try
            {
                out.close();
            }
            catch (IOException e1)
            {
                e1.printStackTrace();
            }
        }
    }
}

A module encapsulates related code into a single unit of code. When creating a module, this can be interpreted as moving all related functions into a file.

Suppose there is a file Hello.js which include two functions

sayHelloInEnglish = function() {
  return "Hello";
};
sayHelloInSpanish = function() {
  return "Hola";
};

We write a function only when utility of the code is more than one call.

Suppose we want to increase utility of the function to a different file say World.js,in this case exporting a file comes into picture which can be obtained by module.exports.

You can just export both the function by the code given below

var anyVariable={
 sayHelloInEnglish = function() {
      return "Hello";
    };
  sayHelloInSpanish = function() {
      return "Hola";
    }; 
}
module.export=anyVariable;

Now you just need to require the file name into World.js inorder to use those functions

var world= require("./hello.js");

Just use 0.0.0.0/0.

host    all             all             0.0.0.0/0            md5

Make sure the listen_addresses in postgresql.conf (or ALTER SYSTEM SET) allows incoming connections on all available IP interfaces.

listen_addresses = '*'

After the changes you have to reload the configuration. One way to do this is execute this SELECT as a superuser.

SELECT pg_reload_conf();

Note: to change listen_addresses, a reload is not enough, and you have to restart the server.

This problem can occur if a class tries to get value of a non-existent key in web.config.

For example, the class has a static variable ClientID

private static string ClientID = System.Configuration.ConfigurationSettings.AppSettings["GoogleCalendarApplicationClientID"].ToString();

but the web.config doesn't contain the 'GoogleCalendarApplicationClientID' key, then the error will be thrown on any static function call or any class instance creation

Tests

On the Tests class we will add an @XmlRootElement annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData property differs from the default mapping we will use the @XmlElement annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted

package forum11221136;

import javax.xml.bind.annotation.*;

@XmlRootElement
public class Tests {

    TestData testData;

    @XmlElement(name="test-data")
    public TestData getTestData() {
        return testData;
    }

    public void setTestData(TestData testData) {
        this.testData = testData;
    }

}

TestData

On this class I used the @XmlType annotation to specify the order in which the elements should be ordered in. I added a testData property that appeared to be missing. I also used an @XmlElement annotation for the same reason as in the Tests class.

package forum11221136;

import java.util.List;
import javax.xml.bind.annotation.*;

@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
    String title;
    String book;
    String count;
    List<TestData> testData;

    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getBook() {
        return book;
    }
    public void setBook(String book) {
        this.book = book;
    }
    public String getCount() {
        return count;
    }
    public void setCount(String count) {
        this.count = count;
    }
    @XmlElement(name="test-data")
    public List<TestData> getTestData() {
        return testData;
    }
    public void setTestData(List<TestData> testData) {
        this.testData = testData;
    }
}

Demo

Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.

package forum11221136;

import java.io.File;
import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Tests.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/forum11221136/input.xml");
        Tests tests = (Tests) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(tests, System.out);
    }

}

on Mac OS X you can use Sequel Pro

In Turkish language, mb_convert_encoding or any other charset conversion did not work.

And also urlencode did not work because of space char converted to + char. It must be %20 for percent encoding.

This one worked!

   $url = rawurlencode($url);
   $url = str_replace("%3A", ":", $url);
   $url = str_replace("%2F", "/", $url);

   $data = file_get_contents($url);

There is no need to kill entire session. In Oracle 18c you could use ALTER SYSTEM CANCEL:

Cancelling a SQL Statement in a Session

You can cancel a SQL statement in a session using the ALTER SYSTEM CANCEL SQL statement.

Instead of terminating a session, you can cancel a high-load SQL statement in a session. When you cancel a DML statement, the statement is rolled back.

ALTER SYSTEM CANCEL SQL 'SID, SERIAL[, @INST_ID][, SQL_ID]';

If @INST_ID is not specified, the instance ID of the current session is used.

If SQL_ID is not specified, the currently running SQL statement in the specified session is terminated.

Whenever is possible is preferable to use class .myclass{} and identifier #myclass{}, so use a dedicated css file or tag <style></style> within an html. Inline style is good to change css option dynamically with javascript.

As mentioned in comments above, the general case is a pain. It is fairly easy if all items are hashable or all items are sortable. However I have recently had to try solve the general case. Here is my solution. I realised after posting that this is a duplicate to a solution above that I missed on the first pass. Anyway, if you use slices rather than list.remove() you can compare immutable sequences.

def sequences_contain_same_items(a, b):
    for item in a:
        try:
            i = b.index(item)
        except ValueError:
            return False
        b = b[:i] + b[i+1:]
    return not b

You can use code:

if let vc = self.storyboard?.instantiateViewController(withIdentifier: "secondViewController") as? secondViewController {
   let appDelegate = UIApplication.shared.delegate as! AppDelegate
   appDelegate.window?.rootViewController = vc
}

In the end you just don't want to be looking for the following line and then having to guess where it started:

<?php } ?>

Technically and functionally they are the same.

Abstration which hide internal detail to outside world for example you create a class(like calculator one of the class) but for end use you provide object of class ,With the help of object they will play and perform operation ,He does't aware what type of mechanism use internally .Object of class in abstract form .

Encapsulation is the technique of making the fields in a class private and providing access to the fields via public methods. If a field is declared private, it cannot be accessed by anyone outside the class, thereby hiding the fields within the class. For this reason, encapsulation is also referred to as data hiding.For example class calculator which contain private methods getAdd,getMultiply .

Mybe above answer will help you to understand the concept .

With ECMAScript 2015 you can export and import multiple classes like this

class Person
{
    constructor()
    {
        this.type = "Person";
    }
}

class Animal{
    constructor()
    {
        this.type = "Animal";
    }
}

module.exports = {
    Person,
    Animal
};

then where you use them:

const { Animal, Person } = require("classes");

const animal = new Animal();
const person = new Person();

In case of name collisions, or you prefer other names you can rename them like this:

const { Animal : OtherAnimal, Person : OtherPerson} = require("./classes");

const animal = new OtherAnimal();
const person = new OtherPerson();

So I changed it so that now it executes after a 300 miliseconds using setTimeout. Seems to be working now.

I have run into this many times when loading data from an Ajax call. I too use .NET, and it takes time to get adjusted to the clientId when using the jQuery selector. To correct the problem that you're having and to avoid having to add a setTimeout property, you can simply put "async: false" in the Ajax call, and it will give the DOM enough time to have the objects back that you are adding to the select. A small sample below:

$.ajax({
    type: "POST",
    url: document.URL + '/PageList',
    data: "{}",
    async: false,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (response) {
        var pages = (typeof response.d) == 'string' ? eval('(' + response.d + ')') : response.d;

        $('#locPage' + locId).find('option').remove();

        $.each(pages, function () {
            $('#locPage' + locId).append(
                $('<option></option>').val(this.PageId).html(this.Name)
            );
        });
    }
});

http://en.wikipedia.org/wiki/Unix_time#History explains a little about the origins of Unix time and the chosen epoch. The definition of unix time and the epoch date went through a couple of changes before stabilizing on what it is now.

But it does not say why exactly 1/1/1970 was chosen in the end.

Notable excerpts from the Wikipedia page:

The first edition Unix Programmer's Manual dated November 3, 1971 defines the Unix time as "the time since 00:00:00, Jan. 1, 1971, measured in sixtieths of a second".

Because of [the] limited range, the epoch was redefined more than once, before the rate was changed to 1 Hz and the epoch was set to its present value.

Several later problems, including the complexity of the present definition, result from Unix time having been defined gradually by usage rather than fully defined to start with.

There is a way to use this with a hidden div but you have to work abit more with the printElement() function and css.

Css:

#SelectorToPrint{
     display: none;
}

Script:

  $("#SelectorToPrint").printElement({ printBodyOptions:{styleToAdd:'padding:10px;margin:10px;display:block', classNameToAdd:'WhatYouWant'}})

This will override the display: none in the new window you open and the content will be displayed on the print-preview page and the div on you site remains hidden.

If by saying without destroying it, you mean to a keep a reference to the children, you can do:

var oldChildren = [];

while(element.hasChildNodes()) {
    oldChildren.push(element.removeChild(element.firstChild));
}

Regarding the original tagging (html css) of your question:

You cannot remove content with CSS. You could only hide it. E.g. you can hide all children of a certain node with:

#someID > * {
    display: none;
}

This doesn't work in IE6 though (but you could use #someID *).

This worked for me. It's simple for simple objects.

class Person {_x000D_
  constructor(firstName, lastName) {_x000D_
    this.firstName = firstName;_x000D_
    this.lastName = lastName;_x000D_
  }_x000D_
  getFullName() {_x000D_
    return this.lastName + " " + this.firstName;_x000D_
  }_x000D_
_x000D_
  static class(obj) {_x000D_
    return new Person(obj.firstName, obj.lastName);_x000D_
  }_x000D_
}_x000D_
_x000D_
var person1 = {_x000D_
  lastName: "Freeman",_x000D_
  firstName: "Gordon"_x000D_
};_x000D_
_x000D_
var gordon = Person.class(person1);_x000D_
console.log(gordon.getFullName());

I was also searching for a simple solution, and this is what I came up with, based on all other answers and my research. Basically, class Person has another constructor, called 'class' which works with a generic object of the same 'format' as Person. I hope this might help somebody as well.

remove .textContent from var t = document.getElementById("p").textContent;

var t = document.getElementById("p");_x000D_
var y = document.createTextNode("This just got added");_x000D_
_x000D_
t.appendChild(y);

<p id ="p">This is some text</p>

Your title question and your example are completely different. I'll start by answering the title question:

$("a").removeAttr("href");

And as far as not requiring an href, the generally accepted way of doing this is:

<a href"#" onclick="doWork(); return false;">link</a>

The return false is necessary so that the href doesn't actually go anywhere.

Hey, this might not be the most ideal solution, but it works for me. I ended up creating a Python-Markdown LaTeX extension.

It adds support for inline math and text expressions using a $math$ and %text% syntax. The extension is a preprocessor that will use latex/dvipng to generate pngs for the respective equations/text and then base64 encode the data to inline the images directly, rather than have external images.

The data is then put in a simple-delimited cache file that encodes the expression to the base64 representation. This limits the number of times latex actually has to be run.

Here is an example:

%Hello, world!% This is regular text, but this: $y = mx + b$ is not.

The output:

$ markdown -x latex test.markdown
<p><img class='latex-inline math-false' alt='Hello, world!' id='Helloworld' src='data:image/png;base64,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'> This is regular text, but this: <img class='latex-inline math-true' alt='y = mx + b' id='ymxb' src='data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAFIAAAAOBAMAAABOTlYkAAAAMFBMVEX///9ERETu7u4yMjK6urp2dnZUVFSIiIjMzMwQEBDc3NwiIiJmZmaYmJiqqqoAAADS00rKAAAAAXRSTlMAQObYZgAAAOtJREFUKM9jYCAACsCk4wYGgiABTLInEKuS+QGxKvkVGBj47jBwI8tcffI84e45BoZ7GVcLECo9751iWLeSoRPITBQEggMMDBy9sxj2MDgz8DIE8yCpPMxwjWFBGUMMkpFcbAEMvxjKGLgYxIE8NkHBiYIyQMY+hmoGhi0Mdsi2czawbGCQBTJ+ILvzE0MaA9MHIIWwnWE9A+sBpk8LGDgmMCnAVXJNYPgCJHhRQvUiA/cDXoECZx4DXoSZTBtYgaaEPw5AVnkOGBRc5xTcbsReQrL9+nWwyxbgC88DcJZ+QygDcYD1+QPiFAIAtLA8KPZOGFEAAAAASUVORK5CYII='> is not.</p>

As you can see it is a verbose output, but that really isn't an issue since you're already using Markdown :)

Note: Most of the answers cover function pointers which is one possibility to achieve "callback" logic in C++, but as of today not the most favourable one I think.

What are callbacks(?) and why to use them(!)

A callback is a callable (see further down) accepted by a class or function, used to customize the current logic depending on that callback.

One reason to use callbacks is to write generic code which is independant from the logic in the called function and can be reused with different callbacks.

Many functions of the standard algorithms library <algorithm> use callbacks. For example the for_each algorithm applies an unary callback to every item in a range of iterators:

template<class InputIt, class UnaryFunction>
UnaryFunction for_each(InputIt first, InputIt last, UnaryFunction f)
{
  for (; first != last; ++first) {
    f(*first);
  }
  return f;
}

which can be used to first increment and then print a vector by passing appropriate callables for example:

std::vector<double> v{ 1.0, 2.2, 4.0, 5.5, 7.2 };
double r = 4.0;
std::for_each(v.begin(), v.end(), [&](double & v) { v += r; });
std::for_each(v.begin(), v.end(), [](double v) { std::cout << v << " "; });

which prints

5 6.2 8 9.5 11.2

Another application of callbacks is the notification of callers of certain events which enables a certain amount of static / compile time flexibility.

Personally, I use a local optimization library that uses two different callbacks:

• The first callback is called if a function value and the gradient based on a vector of input values is required (logic callback: function value determination / gradient derivation).
• The second callback is called once for each algorithm step and receives certain information about the convergence of the algorithm (notification callback).

Thus, the library designer is not in charge of deciding what happens with the information that is given to the programmer via the notification callback and he needn't worry about how to actually determine function values because they're provided by the logic callback. Getting those things right is a task due to the library user and keeps the library slim and more generic.

Furthermore, callbacks can enable dynamic runtime behaviour.

Imagine some kind of game engine class which has a function that is fired, each time the users presses a button on his keyboard and a set of functions that control your game behaviour. With callbacks you can (re)decide at runtime which action will be taken.

void player_jump();
void player_crouch();

class game_core
{
    std::array<void(*)(), total_num_keys> actions;
    // 
    void key_pressed(unsigned key_id)
    {
        if(actions[key_id]) actions[key_id]();
    }
    // update keybind from menu
    void update_keybind(unsigned key_id, void(*new_action)())
    {
        actions[key_id] = new_action;
    }
};

Here the function key_pressed uses the callbacks stored in actions to obtain the desired behaviour when a certain key is pressed. If the player chooses to change the button for jumping, the engine can call

game_core_instance.update_keybind(newly_selected_key, &player_jump);

and thus change the behaviour of a call to key_pressed (which the calls player_jump) once this button is pressed the next time ingame.

What are callables in C++(11)?

See C++ concepts: Callable on cppreference for a more formal description.

Callback functionality can be realized in several ways in C++(11) since several different things turn out to be callable*:

• Function pointers (including pointers to member functions)
• std::function objects
• Lambda expressions
• Bind expressions
• Function objects (classes with overloaded function call operator operator())

_{* Note: Pointer to data members are callable as well but no function is called at all.}

Several important ways to write callbacks in detail

• X.1 "Writing" a callback in this post means the syntax to declare and name the callback type.
• X.2 "Calling" a callback refers to the syntax to call those objects.
• X.3 "Using" a callback means the syntax when passing arguments to a function using a callback.

Note: As of C++17, a call like f(...) can be written as std::invoke(f, ...) which also handles the pointer to member case.

1. Function pointers

A function pointer is the 'simplest' (in terms of generality; in terms of readability arguably the worst) type a callback can have.

Let's have a simple function foo:

int foo (int x) { return 2+x; }

1.1 Writing a function pointer / type notation

A function pointer type has the notation

return_type (*)(parameter_type_1, parameter_type_2, parameter_type_3)
// i.e. a pointer to foo has the type:
int (*)(int)

where a named function pointer type will look like

return_type (* name) (parameter_type_1, parameter_type_2, parameter_type_3)

// i.e. f_int_t is a type: function pointer taking one int argument, returning int
typedef int (*f_int_t) (int); 

// foo_p is a pointer to function taking int returning int
// initialized by pointer to function foo taking int returning int
int (* foo_p)(int) = &foo; 
// can alternatively be written as 
f_int_t foo_p = &foo;

The using declaration gives us the option to make things a little bit more readable, since the typedef for f_int_t can also be written as:

using f_int_t = int(*)(int);

Where (at least for me) it is clearer that f_int_t is the new type alias and recognition of the function pointer type is also easier

And a declaration of a function using a callback of function pointer type will be:

// foobar having a callback argument named moo of type 
// pointer to function returning int taking int as its argument
int foobar (int x, int (*moo)(int));
// if f_int is the function pointer typedef from above we can also write foobar as:
int foobar (int x, f_int_t moo);

1.2 Callback call notation

The call notation follows the simple function call syntax:

int foobar (int x, int (*moo)(int))
{
    return x + moo(x); // function pointer moo called using argument x
}
// analog
int foobar (int x, f_int_t moo)
{
    return x + moo(x); // function pointer moo called using argument x
}

1.3 Callback use notation and compatible types

A callback function taking a function pointer can be called using function pointers.

Using a function that takes a function pointer callback is rather simple:

 int a = 5;
 int b = foobar(a, foo); // call foobar with pointer to foo as callback
 // can also be
 int b = foobar(a, &foo); // call foobar with pointer to foo as callback

1.4 Example

A function ca be written that doesn't rely on how the callback works:

void tranform_every_int(int * v, unsigned n, int (*fp)(int))
{
  for (unsigned i = 0; i < n; ++i)
  {
    v[i] = fp(v[i]);
  }
}

where possible callbacks could be

int double_int(int x) { return 2*x; }
int square_int(int x) { return x*x; }

used like

int a[5] = {1, 2, 3, 4, 5};
tranform_every_int(&a[0], 5, double_int);
// now a == {2, 4, 6, 8, 10};
tranform_every_int(&a[0], 5, square_int);
// now a == {4, 16, 36, 64, 100};

2. Pointer to member function

A pointer to member function (of some class C) is a special type of (and even more complex) function pointer which requires an object of type C to operate on.

struct C
{
    int y;
    int foo(int x) const { return x+y; }
};

2.1 Writing pointer to member function / type notation

A pointer to member function type for some class T has the notation

// can have more or less parameters
return_type (T::*)(parameter_type_1, parameter_type_2, parameter_type_3)
// i.e. a pointer to C::foo has the type
int (C::*) (int)

where a named pointer to member function will -in analogy to the function pointer- look like this:

return_type (T::* name) (parameter_type_1, parameter_type_2, parameter_type_3)

// i.e. a type `f_C_int` representing a pointer to member function of `C`
// taking int returning int is:
typedef int (C::* f_C_int_t) (int x); 

// The type of C_foo_p is a pointer to member function of C taking int returning int
// Its value is initialized by a pointer to foo of C
int (C::* C_foo_p)(int) = &C::foo;
// which can also be written using the typedef:
f_C_int_t C_foo_p = &C::foo;

Example: Declaring a function taking a pointer to member function callback as one of its arguments:

// C_foobar having an argument named moo of type pointer to member function of C
// where the callback returns int taking int as its argument
// also needs an object of type c
int C_foobar (int x, C const &c, int (C::*moo)(int));
// can equivalently declared using the typedef above:
int C_foobar (int x, C const &c, f_C_int_t moo);

2.2 Callback call notation

The pointer to member function of C can be invoked, with respect to an object of type C by using member access operations on the dereferenced pointer. Note: Parenthesis required!

int C_foobar (int x, C const &c, int (C::*moo)(int))
{
    return x + (c.*moo)(x); // function pointer moo called for object c using argument x
}
// analog
int C_foobar (int x, C const &c, f_C_int_t moo)
{
    return x + (c.*moo)(x); // function pointer moo called for object c using argument x
}

Note: If a pointer to C is available the syntax is equivalent (where the pointer to C must be dereferenced as well):

int C_foobar_2 (int x, C const * c, int (C::*meow)(int))
{
    if (!c) return x;
    // function pointer meow called for object *c using argument x
    return x + ((*c).*meow)(x); 
}
// or equivalent:
int C_foobar_2 (int x, C const * c, int (C::*meow)(int))
{
    if (!c) return x;
    // function pointer meow called for object *c using argument x
    return x + (c->*meow)(x); 
}

2.3 Callback use notation and compatible types

A callback function taking a member function pointer of class T can be called using a member function pointer of class T.

Using a function that takes a pointer to member function callback is -in analogy to function pointers- quite simple as well:

 C my_c{2}; // aggregate initialization
 int a = 5;
 int b = C_foobar(a, my_c, &C::foo); // call C_foobar with pointer to foo as its callback

3. std::function objects (header <functional>)

The std::function class is a polymorphic function wrapper to store, copy or invoke callables.

3.1 Writing a std::function object / type notation

The type of a std::function object storing a callable looks like:

std::function<return_type(parameter_type_1, parameter_type_2, parameter_type_3)>

// i.e. using the above function declaration of foo:
std::function<int(int)> stdf_foo = &foo;
// or C::foo:
std::function<int(const C&, int)> stdf_C_foo = &C::foo;

3.2 Callback call notation

The class std::function has operator() defined which can be used to invoke its target.

int stdf_foobar (int x, std::function<int(int)> moo)
{
    return x + moo(x); // std::function moo called
}
// or 
int stdf_C_foobar (int x, C const &c, std::function<int(C const &, int)> moo)
{
    return x + moo(c, x); // std::function moo called using c and x
}

3.3 Callback use notation and compatible types

The std::function callback is more generic than function pointers or pointer to member function since different types can be passed and implicitly converted into a std::function object.

3.3.1 Function pointers and pointers to member functions

A function pointer

int a = 2;
int b = stdf_foobar(a, &foo);
// b == 6 ( 2 + (2+2) )

or a pointer to member function

int a = 2;
C my_c{7}; // aggregate initialization
int b = stdf_C_foobar(a, c, &C::foo);
// b == 11 == ( 2 + (7+2) )

can be used.

3.3.2 Lambda expressions

An unnamed closure from a lambda expression can be stored in a std::function object:

int a = 2;
int c = 3;
int b = stdf_foobar(a, [c](int x) -> int { return 7+c*x; });
// b == 15 ==  a + (7*c*a) == 2 + (7+3*2)

3.3.3 std::bind expressions

The result of a std::bind expression can be passed. For example by binding parameters to a function pointer call:

int foo_2 (int x, int y) { return 9*x + y; }
using std::placeholders::_1;

int a = 2;
int b = stdf_foobar(a, std::bind(foo_2, _1, 3));
// b == 23 == 2 + ( 9*2 + 3 )
int c = stdf_foobar(a, std::bind(foo_2, 5, _1));
// c == 49 == 2 + ( 9*5 + 2 )

Where also objects can be bound as the object for the invocation of pointer to member functions:

int a = 2;
C const my_c{7}; // aggregate initialization
int b = stdf_foobar(a, std::bind(&C::foo, my_c, _1));
// b == 1 == 2 + ( 2 + 7 )

3.3.4 Function objects

Objects of classes having a proper operator() overload can be stored inside a std::function object, as well.

struct Meow
{
  int y = 0;
  Meow(int y_) : y(y_) {}
  int operator()(int x) { return y * x; }
};
int a = 11;
int b = stdf_foobar(a, Meow{8});
// b == 99 == 11 + ( 8 * 11 )

3.4 Example

Changing the function pointer example to use std::function

void stdf_tranform_every_int(int * v, unsigned n, std::function<int(int)> fp)
{
  for (unsigned i = 0; i < n; ++i)
  {
    v[i] = fp(v[i]);
  }
}

gives a whole lot more utility to that function because (see 3.3) we have more possibilities to use it:

// using function pointer still possible
int a[5] = {1, 2, 3, 4, 5};
stdf_tranform_every_int(&a[0], 5, double_int);
// now a == {2, 4, 6, 8, 10};

// use it without having to write another function by using a lambda
stdf_tranform_every_int(&a[0], 5, [](int x) -> int { return x/2; });
// now a == {1, 2, 3, 4, 5}; again

// use std::bind :
int nine_x_and_y (int x, int y) { return 9*x + y; }
using std::placeholders::_1;
// calls nine_x_and_y for every int in a with y being 4 every time
stdf_tranform_every_int(&a[0], 5, std::bind(nine_x_and_y, _1, 4));
// now a == {13, 22, 31, 40, 49};

4. Templated callback type

Using templates, the code calling the callback can be even more general than using std::function objects.

Note that templates are a compile-time feature and are a design tool for compile-time polymorphism. If runtime dynamic behaviour is to be achieved through callbacks, templates will help but they won't induce runtime dynamics.

4.1 Writing (type notations) and calling templated callbacks

Generalizing i.e. the std_ftransform_every_int code from above even further can be achieved by using templates:

template<class R, class T>
void stdf_transform_every_int_templ(int * v,
  unsigned const n, std::function<R(T)> fp)
{
  for (unsigned i = 0; i < n; ++i)
  {
    v[i] = fp(v[i]);
  }
}

with an even more general (as well as easiest) syntax for a callback type being a plain, to-be-deduced templated argument:

template<class F>
void transform_every_int_templ(int * v, 
  unsigned const n, F f)
{
  std::cout << "transform_every_int_templ<" 
    << type_name<F>() << ">\n";
  for (unsigned i = 0; i < n; ++i)
  {
    v[i] = f(v[i]);
  }
}

Note: The included output prints the type name deduced for templated type F. The implementation of type_name is given at the end of this post.

The most general implementation for the unary transformation of a range is part of the standard library, namely std::transform, which is also templated with respect to the iterated types.

template<class InputIt, class OutputIt, class UnaryOperation>
OutputIt transform(InputIt first1, InputIt last1, OutputIt d_first,
  UnaryOperation unary_op)
{
  while (first1 != last1) {
    *d_first++ = unary_op(*first1++);
  }
  return d_first;
}

4.2 Examples using templated callbacks and compatible types

The compatible types for the templated std::function callback method stdf_transform_every_int_templ are identical to the above mentioned types (see 3.4).

Using the templated version however, the signature of the used callback may change a little:

// Let
int foo (int x) { return 2+x; }
int muh (int const &x) { return 3+x; }
int & woof (int &x) { x *= 4; return x; }

int a[5] = {1, 2, 3, 4, 5};
stdf_transform_every_int_templ<int,int>(&a[0], 5, &foo);
// a == {3, 4, 5, 6, 7}
stdf_transform_every_int_templ<int, int const &>(&a[0], 5, &muh);
// a == {6, 7, 8, 9, 10}
stdf_transform_every_int_templ<int, int &>(&a[0], 5, &woof);

Note: std_ftransform_every_int (non templated version; see above) does work with foo but not using muh.

// Let
void print_int(int * p, unsigned const n)
{
  bool f{ true };
  for (unsigned i = 0; i < n; ++i)
  {
    std::cout << (f ? "" : " ") << p[i]; 
    f = false;
  }
  std::cout << "\n";
}

The plain templated parameter of transform_every_int_templ can be every possible callable type.

int a[5] = { 1, 2, 3, 4, 5 };
print_int(a, 5);
transform_every_int_templ(&a[0], 5, foo);
print_int(a, 5);
transform_every_int_templ(&a[0], 5, muh);
print_int(a, 5);
transform_every_int_templ(&a[0], 5, woof);
print_int(a, 5);
transform_every_int_templ(&a[0], 5, [](int x) -> int { return x + x + x; });
print_int(a, 5);
transform_every_int_templ(&a[0], 5, Meow{ 4 });
print_int(a, 5);
using std::placeholders::_1;
transform_every_int_templ(&a[0], 5, std::bind(foo_2, _1, 3));
print_int(a, 5);
transform_every_int_templ(&a[0], 5, std::function<int(int)>{&foo});
print_int(a, 5);

The above code prints:

1 2 3 4 5
transform_every_int_templ <int(*)(int)>
3 4 5 6 7
transform_every_int_templ <int(*)(int&)>
6 8 10 12 14
transform_every_int_templ <int& (*)(int&)>
9 11 13 15 17
transform_every_int_templ <main::{lambda(int)#1} >
27 33 39 45 51
transform_every_int_templ <Meow>
108 132 156 180 204
transform_every_int_templ <std::_Bind<int(*(std::_Placeholder<1>, int))(int, int)>>
975 1191 1407 1623 1839
transform_every_int_templ <std::function<int(int)>>
977 1193 1409 1625 1841

type_name implementation used above

#include <type_traits>
#include <typeinfo>
#include <string>
#include <memory>
#include <cxxabi.h>

template <class T>
std::string type_name()
{
  typedef typename std::remove_reference<T>::type TR;
  std::unique_ptr<char, void(*)(void*)> own
    (abi::__cxa_demangle(typeid(TR).name(), nullptr,
    nullptr, nullptr), std::free);
  std::string r = own != nullptr?own.get():typeid(TR).name();
  if (std::is_const<TR>::value)
    r += " const";
  if (std::is_volatile<TR>::value)
    r += " volatile";
  if (std::is_lvalue_reference<T>::value)
    r += " &";
  else if (std::is_rvalue_reference<T>::value)
    r += " &&";
  return r;
}

I'd suggest a regex approach. A full regex-match (for example, using boost::regex) with

-?[0-9]+([\.][0-9]+)?

would show whether the string is a number or not. This includes positive and negative numbers, integer as well as decimal.

Other variations:

[0-9]+([\.][0-9]+)?

(only positive)

-?[0-9]+

(only integer)

[0-9]+

(only positive integer)

The main differences between InnoDB and MyISAM ("with respect to designing a table or database" you asked about) are support for "referential integrity" and "transactions".

If you need the database to enforce foreign key constraints, or you need the database to support transactions (i.e. changes made by two or more DML operations handled as single unit of work, with all of the changes either applied, or all the changes reverted) then you would choose the InnoDB engine, since these features are absent from the MyISAM engine.

Those are the two biggest differences. Another big difference is concurrency. With MyISAM, a DML statement will obtain an exclusive lock on the table, and while that lock is held, no other session can perform a SELECT or a DML operation on the table.

Those two specific engines you asked about (InnoDB and MyISAM) have different design goals. MySQL also has other storage engines, with their own design goals.

So, in choosing between InnoDB and MyISAM, the first step is in determining if you need the features provided by InnoDB. If not, then MyISAM is up for consideration.

A more detailed discussion of differences is rather impractical (in this forum) absent a more detailed discussion of the problem space... how the application will use the database, how many tables, size of the tables, the transaction load, volumes of select, insert, updates, concurrency requirements, replication features, etc.

The logical design of the database should be centered around data analysis and user requirements; the choice to use a relational database would come later, and even later would the choice of MySQL as a relational database management system, and then the selection of a storage engine for each table.

Here's yet another way, using pure NumPy, no recursion, no list comprehension, and no explicit for loops. It's about 20% slower than the original answer, and it's based on np.meshgrid.

def cartesian(*arrays):
    mesh = np.meshgrid(*arrays)  # standard numpy meshgrid
    dim = len(mesh)  # number of dimensions
    elements = mesh[0].size  # number of elements, any index will do
    flat = np.concatenate(mesh).ravel()  # flatten the whole meshgrid
    reshape = np.reshape(flat, (dim, elements)).T  # reshape and transpose
    return reshape

For example,

x = np.arange(3)
a = cartesian(x, x, x, x, x)
print(a)

gives

[[0 0 0 0 0]
 [0 0 0 0 1]
 [0 0 0 0 2]
 ..., 
 [2 2 2 2 0]
 [2 2 2 2 1]
 [2 2 2 2 2]]

Use the json module to produce JSON output:

import json

with open(outputfilename, 'wb') as outfile:
    json.dump(row, outfile)

This writes the JSON result directly to the file (replacing any previous content if the file already existed).

If you need the JSON result string in Python itself, use json.dumps() (added s, for 'string'):

json_string = json.dumps(row)

The L is just Python syntax for a long integer value; the json library knows how to handle those values, no L will be written.

Demo string output:

>>> import json

There is simple answer in the official guide:

What does it not do?

It does not cause a full page reload when the browser URL is changed. To reload the page after changing the URL, use the lower-level API, $window.location.href.

Uncommenting set bell-style none in /etc/inputrc and creating a .bash_profile with setterm -blength 0 didn't stop vim from beeping.

What worked for me was creating a .vimrc file in my home directory with set visualbell.

The trick is to use "DateTime" to manipulate dates; only use integers and strings when you need a "final result" from the date.

For example (pseudo code):

1. Get "DateTime tomorrow = Now + 1"

2. Determine date, day of week, day of month - whatever you want - of the resulting date.

You have to manually filter result based on change of input each time by keeping listener over input event. While doing manually filtering make sure you should maintain two copy of variable, one would be original collection copy & second would be filteredCollection copy. The advantage for going this way could save your couple of unnecessary filtering on change detection cycle. You may see a more code, but this would be more performance friendly.

Markup - HTML Template

<md-input #myInput placeholder="Item name..." [(ngModel)]="name" (input)="filterItem(myInput.value)"></md-input>

<div *ngFor="let item of filteredItems">
   {{item.name}}
</div>

Code

assignCopy(){
   this.filteredItems = Object.assign([], this.items);
}
filterItem(value){
   if(!value){
       this.assignCopy();
   } // when nothing has typed
   this.filteredItems = Object.assign([], this.items).filter(
      item => item.name.toLowerCase().indexOf(value.toLowerCase()) > -1
   )
}
this.assignCopy();//when you fetch collection from server.

The isinstance built-in is the preferred way if you really must, but even better is to remember Python's motto: "it's easier to ask forgiveness than permission"!-) (It was actually Grace Murray Hopper's favorite motto;-). I.e.:

def my_print(text, begin, end):
    "Print 'text' in UPPER between 'begin' and 'end' in lower"
    try:
      print begin.lower() + text.upper() + end.lower()
    except (AttributeError, TypeError):
      raise AssertionError('Input variables should be strings')

This, BTW, lets the function work just fine on Unicode strings -- without any extra effort!-)

In Spring properties files, you can't just specify a number for this property. You also need to specify a unit. So you can say spring.mvc.async.request-timeout=5000ms or spring.mvc.async.request-timeout=5s, both of which will give you a 5-second timeout.

if (code.indexOf("ST1")>=0) { location = "stoke central"; }

There is Q objects that allow to complex lookups. Example:

from django.db.models import Q

Item.objects.filter(Q(creator=owner) | Q(moderated=False))

Please try with autocomplete="none" in your input tag

This works for me

Comparing 2 arrays:

var arr1 = [1,2,3];
var arr2 = [1,2,3];

function compare(arr1,arr2)
{
  if((arr1 == arr2) && (arr1.length == arr2.length))
    return true;
  else
    return false;
}

calling function

var isBool = compare(arr1.sort().join(),arr2.sort().join());

Give width of image as match_parent and height as required, say 300 dp.

<ImageView
    android:id = "@+id/imgXYZ"
    android:layout_width = "match_parent"
    android:layout_height = "300dp"
    android:src="@drawable/imageXYZ"
    />

I use this simple utility function:

rows = function(tab) lapply(
  seq_len(nrow(tab)),
  function(i) unclass(tab[i,,drop=F])
)

Or a faster, less clear form:

rows = function(x) lapply(seq_len(nrow(x)), function(i) lapply(x,"[",i))

This function just splits a data.frame to a list of rows. Then you can make a normal "for" over this list:

tab = data.frame(x = 1:3, y=2:4, z=3:5)
for (A in rows(tab)) {
    print(A$x + A$y * A$z)
}        

Your code from the question will work with a minimal modification:

for (well in rows(dataFrame)) {
  wellName <- well$name    # string like "H1"
  plateName <- well$plate  # string like "plate67"
  wellID <- getWellID(wellName, plateName)
  cat(paste(wellID, well$value1, well$value2, sep=","), file=outputFile)
}

Adaptation of @AndiDog version for big file:

    SHA256_CTX context;
    if(!SHA256_Init(&context))

        return std::nullopt;
    }

    // Read file and update calculated SHA
    char buf[K_READ_BUF_SIZE];
    std::ifstream file(filename, std::ifstream::binary);
    while (file.good())
    {
        file.read(buf, sizeof(buf));

        {
            return std::nullopt;

    unsigned char result[SHA256_DIGEST_LENGTH];
    if(!SHA256_Final(result, &context))
    {
        return std::nullopt;
    }

Wildcards can only be used in the ServerAlias rather than the ServerName. Something which had me stumped.

For your use case, the following should suffice

<VirtualHost *:80>
    ServerAlias *.example.com
    VirtualDocumentRoot /var/www/%1/
</VirtualHost>

@Html.TextBoxFor(model => model.IsActive, new { readonly= "readonly" })

This is just fine for text box. However, if you try to do same for the checkbox then try using this if you are using it:

@Html.CheckBoxFor(model => model.IsActive, new { onclick = "return false" })

But don't use disable, because disable always sends the default value false to the server - either it was in the checked or unchecked state. And the readonly does not work for checkbox and radio button. readonly only works for text fields.

You can support both query parameters and path parameters, e.g., in the case of aggregation of resources -- when the collection of sub-resources makes sense on its own.

/departments/{id}/employees
/employees?dept=id

Query parameters can support hierarchical and non-hierarchical subsetting; path parameters are hierarchical only.

Resources can exhibit multiple hierarchies. Support short paths if you will be querying broad sub-collections that cross hierarchical boundaries.

/inventory?make=toyota&model=corolla
/inventory?year=2014

Use query parameters to combine orthogonal hierarchies.

/inventory/makes/toyota/models/corolla?year=2014
/inventory/years/2014?make=toyota&model=corolla
/inventory?make=toyota&model=corolla&year=2014

Use only path parameters in the case of composition -- when a resource doesn't make sense divorced from its parent, and the global collection of all children is not a useful resource in itself.

/words/{id}/definitions
/definitions?word=id   // not useful

(I'm going to ignore handling input, its just a distraction.)

The easy way is to sort it.

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

int cmp_int( const void *a, const void *b ) {
    return *(int*)a - *(int*)b;
}

int main() {
    int a[] = { 1, 5, 3, 2, 0, 5, 7, 6 };
    const int n = sizeof(a) / sizeof(a[0]);

    qsort(a, n, sizeof(a[0]), cmp_int);
    printf("%d %d\n", a[n-1], a[n-2]);
}

But that isn't the most efficient because it's O(n log n), meaning as the array gets bigger the number of comparisons gets bigger faster. Not too fast, slower than exponential, but we can do better.

We can do it in O(n) or "linear time" meaning as the array gets bigger the number of comparisons grows at the same rate.

Loop through the array tracking the max, that's the usual way to find the max. When you find a new max, the old max becomes the 2nd highest number.

Instead of having a second loop to find the 2nd highest number, throw in a special case for running into the 2nd highest number.

#include <stdio.h>
#include <limits.h>

int main() {
    int a[] = { 1, 5, 3, 2, 0, 5, 7, 6 };
    // This trick to get the size of an array only works on stack allocated arrays.
    const int n = sizeof(a) / sizeof(a[0]);

    // Initialize them to the smallest possible integer.
    // This avoids having to special case the first elements.
    int max = INT_MIN;
    int second_max = INT_MIN;

    for( int i = 0; i < n; i++ ) {
        // Is it the max?
        if( a[i] > max ) {
            // Make the old max the new 2nd max.
            second_max = max;
            // This is the new max.
            max = a[i];
        }
        // It's not the max, is it the 2nd max?
        else if( a[i] > second_max ) {
            second_max = a[i];
        }
    }

    printf("max: %d, second_max: %d\n", max, second_max);
}

There might be a more elegant way to do it, but that will do, at most, 2n comparisons. At best it will do n.

Note that there's an open question of what to do with { 1, 2, 3, 3 }. Should that return 3, 3 or 2, 3? I'll leave that to you to decide and adjust accordingly.

There's a promising javascript library called Arrive that looks like a great way to start taking advantage of the mutation observers once the browser support becomes commonplace.

Perhaps you can use the built-in methods for finding particular items in an Array, instead of each-ing targets and doing everything by hand. A few examples:

class Array
  def first_frog
    detect {|i| i =~ /frog/ }
  end

  def last_frog
    select {|i| i =~ /frog/ }.last
  end
end

p ["dog", "cat", "godzilla", "dogfrog", "woot", "catfrog"].first_frog
# => "dogfrog"
p ["hats", "coats"].first_frog
# => nil
p ["houses", "frogcars", "bottles", "superfrogs"].last_frog
# => "superfrogs"

One example would be doing something like this:

class Bar
  def do_things
    Foo.some_method(x) do |i|
      # only valid `targets` here, yay.
    end
  end
end

class Foo
  def self.failed
    @failed ||= []
  end

  def self.some_method(targets, &block)
    targets.reject {|t| t.do_something.bad? }.each(&block)
  end
end

Use another constant instead of Calendar.HOUR, use Calendar.HOUR_OF_DAY.

calendar.set(Calendar.HOUR_OF_DAY, 0);

Calendar.HOUR uses 0-11 (for use with AM/PM), and Calendar.HOUR_OF_DAY uses 0-23.

To quote the Javadocs:

public static final int HOUR

Field number for get and set indicating the hour of the morning or afternoon. HOUR is used for the 12-hour clock (0 - 11). Noon and midnight are represented by 0, not by 12. E.g., at 10:04:15.250 PM the HOUR is 10.

and

public static final int HOUR_OF_DAY

Field number for get and set indicating the hour of the day. HOUR_OF_DAY is used for the 24-hour clock. E.g., at 10:04:15.250 PM the HOUR_OF_DAY is 22.

Testing ("now" is currently c. 14:55 on July 23, 2013 Pacific Daylight Time):

public class Main
{
   static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    public static void main(String[] args)
    {
        Calendar now = Calendar.getInstance();
        now.set(Calendar.HOUR, 0);
        now.set(Calendar.MINUTE, 0);
        now.set(Calendar.SECOND, 0);
        System.out.println(sdf.format(now.getTime()));
        now.set(Calendar.HOUR_OF_DAY, 0);
        System.out.println(sdf.format(now.getTime()));
    }
}

Output:

$ javac Main.java
$ java Main
2013-07-23 12:00:00
2013-07-23 00:00:00

The columns that needs to be converted to int can be mentioned in a dictionary also as below

df = df.astype({'col1': 'int', 'col2': 'int', 'col3': 'int'})

I recently needed to solve this problem as well and ended up writing a Ruby script for this: https://github.com/vaneyckt/git-find-branching-point

It is very important to notice that, as of HTML5, <wbr> and ­ are not supposed to do the same thing!

Soft hyphens

­ is a soft hyphen, i.e., U+00AD: SOFT HYPHEN. For example,

innehålls­förteckning

might be rendered as

innehållsförteckning

or as

innehålls-
förteckning

As of today, soft hyphens work in Firefox, Chrome, and Internet Explorer.

The wbr element

The wbr element is a word-break opportunity, which will not display a hyphen if a line break occurs. For example,

ABCDEFG<wbr/>abcdefg

might be rendered as

ABCDEFGabcdefg

or as

ABCDEFG
abcdefg

As of today, this element works in Firefox and Chrome.

I created a button...

This is where you've gone wrong. You haven't created a button, you've created an anchor element. If you had used a button element instead, you wouldn't have this problem:

<button type="button" data-toggle="modal" data-target="#myModal" data-role="disabled">
    Connect
</button>

If you are going to continue using an a element instead, at the very least you should give it a role attribute set to "button" and drop the href attribute altogether:

<a role="button" ...>

Once you've done that you can introduce a piece of JavaScript which calls event.preventDefault() - here with event being your click event.

Whenever you want to extend the properties of User.Identity with any additional properties like the question above, add these properties to the ApplicationUser class first like so:

public class ApplicationUser : IdentityUser
{
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        return userIdentity;
    }

    // Your Extended Properties
    public long? OrganizationId { get; set; }
}

Then what you need is to create an extension method like so (I create mine in an new Extensions folder):

namespace App.Extensions
{
    public static class IdentityExtensions
    {
        public static string GetOrganizationId(this IIdentity identity)
        {
            var claim = ((ClaimsIdentity)identity).FindFirst("OrganizationId");
            // Test for null to avoid issues during local testing
            return (claim != null) ? claim.Value : string.Empty;
        }
    }
}

When you create the Identity in the ApplicationUser class, just add the Claim -> OrganizationId like so:

    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here => this.OrganizationId is a value stored in database against the user
        userIdentity.AddClaim(new Claim("OrganizationId", this.OrganizationId.ToString()));

        return userIdentity;
    }

Once you added the claim and have your extension method in place, to make it available as a property on your User.Identity, add a using statement on the page/file you want to access it:

in my case: using App.Extensions; within a Controller and @using. App.Extensions withing a .cshtml View file.

EDIT:

What you can also do to avoid adding a using statement in every View is to go to the Views folder, and locate the Web.config file in there. Now look for the <namespaces> tag and add your extension namespace there like so:

<add namespace="App.Extensions" />

Save your file and you're done. Now every View will know of your extensions.

You can access the Extension Method:

var orgId = User.Identity.GetOrganizationId();

I know, it is long ago, but since the easiest answer was not yet posted I will do so for other user that might step by.

Just move the var inside the "name" block:

- name: Download apache
  vars:
    url: czxcxz
  shell: wget {{url}} 

An NSMutableArray is a subclass of NSArray so you won't always need to convert but if you want to make sure that the array can't be modified you can create a NSArray either of these ways depending on whether you want it autoreleased or not:

/* Not autoreleased */
NSArray *array = [[NSArray alloc] initWithArray:mutableArray];

/* Autoreleased array */
NSArray *array = [NSArray arrayWithArray:mutableArray];

EDIT: The solution provided by Georg Schölly is a better way of doing it and a lot cleaner, especially now that we have ARC and don't even have to call autorelease.

An update for those trying to use MultipartEntity...

org.apache.http.entity.mime.MultipartEntity is deprecated in 4.3.1.

You can use MultipartEntityBuilder to create the HttpEntity object.

File file = new File();

HttpEntity httpEntity = MultipartEntityBuilder.create()
    .addBinaryBody("file", file, ContentType.create("image/jpeg"), file.getName())
    .build();

For Maven users the class is available in the following dependency (almost the same as fervisa's answer, just with a later version).

<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpmime</artifactId>
  <version>4.3.1</version>
</dependency>

Wrote a small class for doing this cleanly.

import tempfile

class FileModifierError(Exception):
    pass

class FileModifier(object):

    def __init__(self, fname):
        self.__write_dict = {}
        self.__filename = fname
        self.__tempfile = tempfile.TemporaryFile()
        with open(fname, 'rb') as fp:
            for line in fp:
                self.__tempfile.write(line)
        self.__tempfile.seek(0)

    def write(self, s, line_number = 'END'):
        if line_number != 'END' and not isinstance(line_number, (int, float)):
            raise FileModifierError("Line number %s is not a valid number" % line_number)
        try:
            self.__write_dict[line_number].append(s)
        except KeyError:
            self.__write_dict[line_number] = [s]

    def writeline(self, s, line_number = 'END'):
        self.write('%s\n' % s, line_number)

    def writelines(self, s, line_number = 'END'):
        for ln in s:
            self.writeline(s, line_number)

    def __popline(self, index, fp):
        try:
            ilines = self.__write_dict.pop(index)
            for line in ilines:
                fp.write(line)
        except KeyError:
            pass

    def close(self):
        self.__exit__(None, None, None)

    def __enter__(self):
        return self

    def __exit__(self, type, value, traceback):
        with open(self.__filename,'w') as fp:
            for index, line in enumerate(self.__tempfile.readlines()):
                self.__popline(index, fp)
                fp.write(line)
            for index in sorted(self.__write_dict):
                for line in self.__write_dict[index]:
                    fp.write(line)
        self.__tempfile.close()

Then you can use it this way:

with FileModifier(filename) as fp:
    fp.writeline("String 1", 0)
    fp.writeline("String 2", 20)
    fp.writeline("String 3")  # To write at the end of the file

Try this:

valgrind --leak-check=full -v ./your_program

As long as valgrind is installed it will go through your program and tell you what's wrong. It can give you pointers and approximate places where your leaks may be found. If you're segfault'ing, try running it through gdb.

How about creating an ArrayList of a set amount of Integers?

The below method returns an ArrayList of a set amount of Integers.

public static ArrayList<Integer> createRandomList(int sizeParameter)
{
    // An ArrayList that method returns
    ArrayList<Integer> setIntegerList = new ArrayList<Integer>(sizeParameter);
    // Random Object helper
    Random randomHelper = new Random();
    
    for (int x = 0; x < sizeParameter; x++)
    {
        setIntegerList.add(randomHelper.nextInt());
    }   // End of the for loop
    
    return setIntegerList;
}

You may use:

• Array.prototype.map()
• Array.prototype.reduce()
• Arrow functions
• Comma operator

To create array of objects:

var source = ['left', 'top'];
const result = source.map(arrValue => ({[arrValue]: 0}));

Demo:

var source = ['left', 'top'];_x000D_
_x000D_
const result = source.map(value => ({[value]: 0}));_x000D_
_x000D_
console.log(result);

Or if you wants to create a single object from values of arrays:

var source = ['left', 'top'];
const result = source.reduce((obj, arrValue) => (obj[arrValue] = 0, obj), {});

Demo:

var source = ['left', 'top'];_x000D_
_x000D_
const result = source.reduce((obj, arrValue) => (obj[arrValue] = 0, obj), {});_x000D_
_x000D_
console.log(result);
