Some Android phones contain Busybox. Was hard to find.

To see if busybox was around:

ls -lR / | grep busybox

If you know it's around. You need some read/write space. Try you flash drive, /sdcard

cd /sdcard
ls -lR / >lsoutput.txt

upload to your computer. Upload the file. Get some text editor. Search for busybox. Will see what directory the file was found in.

busybox find /sdcard -iname 'python*'

to make busybox easier to access, you could:

cd /sdcard
ln -s /where/ever/busybox/is  busybox
/sdcard/busybox find /sdcard -iname 'python*'

Or any other place you want. R

Module in Ruby, to a degree, corresponds to Java abstract class -- has instance methods, classes can inherit from it (via include, Ruby guys call it a "mixin"), but has no instances. There are other minor differences, but this much information is enough to get you started.

Following @Francisco Goldenstein answer, I wrote an extension method

using System.Collections.Generic;
using System.Linq;
using System.Xml.Linq;

namespace Mediatel.Framework
{
    public static class XDocumentHelper
    {
        public static IEnumerable<XElement> DescendantElements(this XDocument xDocument, string nodeName)
        {
            return xDocument.Descendants().Where(p => p.Name.LocalName == nodeName);
        }
    }
}

To ensure a field value is unique you can write

@Column(unique=true)
String username;

The @UniqueConstraint annotation is for annotating multiple unique keys at the table level, which is why you get an error when applying it to a field.

References (JPA TopLink):

• @UniqueConstraint
• @Column

A quite frequent issue is that a batch script is run by double-clicking its icon. Since the hosting Command Prompt (cmd.exe) instance also terminates as soon as the batch script is finished, it is not possible to read potential output and error messages.

To read such messages, it is very important that you explicitly open a Command Prompt window, manoeuvre to the applicable working directory and run the batch script by typing its path/name.

In general you want to program against an interface. This allows you to exchange the implementation at any time. This is very useful especially when you get passed an implementation you don't know.

However, there are certain situations where you prefer to use the concrete implementation. For example when serialize in GWT.

Try this.

<span style="padding-right:3px; padding-top: 3px; display:inline-block;">

<img class="manImg" src="images/ico_mandatory.gif"></img>

</span>

If You want to find a specific object via search function just try something like this:

    function findArray(value){

        let countLayer = dataLayer.length;
        for(var x = 0 ; x < countLayer ; x++){

            if(dataLayer[x].user){
                let newArr = dataLayer[x].user;
                let data = newArr[value];
                return data;
            }

        }

        return null;

    }

    findArray("id");

This is an example object:

layerObj = {
    0: { gtm.start :1232542, event: "gtm.js"},
    1: { event: "gtm.dom", gtm.uniqueEventId: 52},
    2: { visitor id: "abcdef2345"},
    3: { user: { id: "29857239", verified: "Null", user_profile: "Personal", billing_subscription: "True", partners_user: "adobe"}
}

Code will iterate and find the "user" array and will search for the object You seek inside.

My problem was when the array index changed every window refresh and it was either in 3rd or second array, but it does not matter.

Worked like a charm for Me!

In Your example it is a bit shorter:

function findArray(value){

    let countLayer = Object.length;
    for(var x = 0 ; x < countLayer ; x++){

        if(Object[x].dinner === value){
            return Object[x];
        }

    }

    return null;

}

findArray('sushi');

You can try this.

npm install --only=dev

It works for me.

To make a supplement, if you are reading file that contains a line that is vvvvery huge, which might break your memory, you might consider read them into a buffer then yield the each char

def read_char(inputfile, buffersize=10240):
    with open(inputfile, 'r') as f:
        while True:
            buf = f.read(buffersize)
            if not buf:
                break
            for char in buf:
                yield char
        yield '' #handle the scene that the file is empty

if __name__ == "__main__":
    for word in read_char('./very_large_file.txt'):
        process(char)

You could check whether the value of your selectOneMenu component belongs to the list of subjects.

Namely:

public void subjectSelectionChanged() {
    // Cancel if subject is manually written
    if (!subjectList.contains(aktNachricht.subject)) { return; }
    // Write your code here in case the user selected (or wrote) an item of the list
    // ....
}

Supposedly subjectList is a collection type, like ArrayList. Of course here your code will run in case the user writes an item of your selectOneMenu list.

For Windows, you can run this command directly if mysql/bin is in your path.

mysqladmin -u root -p shutdown

Pseudo elements are part of the shadow DOM and can not be modified (but can have their values queried).

However, sometimes you can get around that by using classes, for example.

jQuery

$('#element').addClass('some-class');

CSS

.some-class:before {
    /* change your properties here */
}

This may not be suitable for your query, but it does demonstrate you can achieve this pattern sometimes.

To get a pseudo element's value, try some code like...

var pseudoElementContent = window.getComputedStyle($('#element')[0], ':before')
  .getPropertyValue('content')

This is a String, not a json structure(key, value), try:

return new ResponseEntity("{"vale" : "This is a String"}", HttpStatus.OK);

DATEADD only returned Function does not exist on MySQL 5.5.53 (I know it's old)

Instead, I found DatePlayed > DATE_SUB(CURRENT_TIMESTAMP, INTERVAL 30 minute) to produce the desired result

Be very careful when cloning ArrayLists. Cloning in java is shallow. This means that it will only clone the Arraylist itself and not its members. So if you have an ArrayList X1 and clone it into X2 any change in X2 will also manifest in X1 and vice-versa. When you clone you will only generate a new ArrayList with pointers to the same elements in the original.

if you use the site http://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python , download the file:

• mysqlclient-1.3.6-cp34-none-win32.whl or

• mysqlclient-1.3.6-cp34-none-win_amd64.whl

depending on the version of python you have (these are for python 3.4) and the type of windows you have (x64 or x32)

extract this file into C:\Python34\Lib\site-packages and your project will work

You'll have to parse again if you want it in actual JSON:

JSON.parse(JSON.stringify(object))

You don't need to use a subclass of Thread to make this work - take a look at the simple example I'm posting below to see how:

from threading import Thread
from time import sleep

def threaded_function(arg):
    for i in range(arg):
        print("running")
        sleep(1)


if __name__ == "__main__":
    thread = Thread(target = threaded_function, args = (10, ))
    thread.start()
    thread.join()
    print("thread finished...exiting")

Here I show how to use the threading module to create a thread which invokes a normal function as its target. You can see how I can pass whatever arguments I need to it in the thread constructor.

You can change the cookie time session feature at phpmyadmin web interface

Settings->Features->General->Login cookie validity

OR

If you want to change the 'login cookie validity' in configuration file, then open the phpmMyAdmin configuration file, config.inc.php in the root directory of PHPMyAdmin.(root directory is usually /etc/phpmyadmin/)

After locating the config.inc.php , search for the line below and set it to the value of seconds you want phpmyadmin to timeout:

$cfg['LoginCookieValidity'] 

or

Add the following:

$cfg[ ' Servers'] [$i] [ ' LoginCookieValidity' ] = <your_new_timeout>;

For example:

$cfg[ ' Servers'] [$i] [ ' LoginCookieValidity' ] = <3600 * 3 >;

The Timeout is set to 3 Hours from the Example above.

session.gc_maxlifetime might limit session validity and if the session is lost, the login cookie is also invalidated. So, we may need to set the session.gc_maxlifetime in php.ini configuration file(file location is /etc/php5 /apache2/php.ini in ubuntu).

session.gc_maxlifetime = 3600 * 3

$cfg['LoginCookieValidity']

Type: integer [number of seconds]
Default value: 1440

Define how long a login cookie is valid. Please note that php configuration option session.gc_maxlifetime might limit session validity and if the session is lost, the login cookie is also invalidated. So it is a good idea to set session.gc_maxlifetime at least to the same value of $cfg['LoginCookieValidity'].

NOTE:

1. If your server crashed and cannot load your phpmyadmin page, check your apache log at /var/log/apache2/error.log. If you got PHP Fatal error: Call to a member function get() on a non-object in /path/to/phpmyadmin/libraries/Header.class.php on line 135, then do a chmod 644 config.inc.php. that should take care of the error.
2. You will then get another warning: Your PHP parameter session.gc_maxlifetime is lower that cookie validity configured in phpMyAdmin, because of this, your login will expire sooner than configured in phpMyAdmin.. then change the session.gc_maxlifetime as mentioned above.

Integer.toString(1100) gives you the integer as a string. Integer.toString(1100).getBytes() to get an array of bytes of the individual digits.

Edit:

You can convert the character digits into numeric digits, thus:

  String string = Integer.toString(1234);
  int[] digits = new int[string.length()];

  for(int i = 0; i<string.length(); ++i){
    digits[i] = Integer.parseInt(string.substring(i, i+1));
  }
  System.out.println("digits:" + Arrays.toString(digits));

Here's a solution, based on jQuery and a mouse event listener (which is far better than a regular polling) on the body:

$("body").mousemove(function(e) {
    document.Form1.posx.value = e.pageX;
    document.Form1.posy.value = e.pageY;
})

While I don't think there is a way to fully do this you can take a few measures to stop almost everyone from viewing the HTML.

You can first of all try and stop the inspect menu by doing the following:

<body oncontextmenu="return false" onkeydown="return false;" onmousedown="return false;">

I would also suggest using the method that Jonas gave of using his javascript and putting what you don't want people to see in a div with id="element-to-hide" and his given js script to furthermore stop people from inspecting.

I'm pretty sure that it's quite hard to get past that. But then someone can just type view-source:www.exapmle.com and that will show them the source. So you will then probably want to encrypt the HTML(I would advise using a website that gives you an extended security option). There are plenty of good websites that do this for free (eg:http://www.smartgb.com/free_encrypthtml.php) and use extended security which you can't usually unencrypt through HTML un encryptors.

This will basically encrypt your HTML so if you view the source using the method I showed above you will just get encrypted HTML(that is also extremely difficult to unencrypt if you used the extended security option). But you can view the unencrypted HTML through inspecting but we have already blocked that(to a very reasonable extent)

Ok so you can't fully hide the HTML but you can do an extremely good job at stopping people seeing it.(If you think about it most people don't care about looking at a page's HTML, some people don't even know about inspecting and viewing the source and the people who do probably won't be bothered or won't be able to get past theses implications! So probably no one will see you HTML)

(Hope this helps!)

First get the text from edit text view

edittext.getText().toString()

and Store the obtained text in a string, say value.

value = edittext.getText().toString()

Then set value as the text for textview.

textview.setText(value)

Predicate falls under the category of generic delegates in C#. This is called with one argument and always return the boolean type. Basically, the predicate is used to test the condition - true/false. Many classes support predicate as an argument. For example, list.findall expects the parameter predicate. Here is an example of predicate.

Imagine a function pointer with the signature:

<modifier> bool delegate myDelegate<in T>(T match);

Here is the example:

Node.cs:

namespace PredicateExample
{
    class Node
    {
        public string Ip_Address { get; set; }
        public string Node_Name { get; set; }
        public uint Node_Area { get; set; }
    }
}

Main class:

using System;
using System.Threading;
using System.Collections.Generic;

namespace PredicateExample
{
    class Program
    {
        static void Main(string[] args)
        {
            Predicate<Node> backboneArea = Node =>  Node.Node_Area == 0 ;
            List<Node> Nodes = new List<Node>();
            Nodes.Add(new Node { Ip_Address = "1.1.1.1", Node_Area = 0, Node_Name = "Node1" });
            Nodes.Add(new Node { Ip_Address = "2.2.2.2", Node_Area = 1, Node_Name = "Node2" });
            Nodes.Add(new Node { Ip_Address = "3.3.3.3", Node_Area = 2, Node_Name = "Node3" });
            Nodes.Add(new Node { Ip_Address = "4.4.4.4", Node_Area = 0, Node_Name = "Node4" });
            Nodes.Add(new Node { Ip_Address = "5.5.5.5", Node_Area = 1, Node_Name = "Node5" });
            Nodes.Add(new Node { Ip_Address = "6.6.6.6", Node_Area = 0, Node_Name = "Node6" });
            Nodes.Add(new Node { Ip_Address = "7.7.7.7", Node_Area = 2, Node_Name = "Node7" });

            foreach( var item in Nodes.FindAll(backboneArea))
            {
                Console.WriteLine("Node Name " + item.Node_Name + " Node IP Address " + item.Ip_Address);
            }

            Console.ReadLine();
        }
    }
}

Prior answers focused on nominal data (e.g. unordered). If there is a reason to impose order for an ordinal variable, then one would use:

# Transform to category
df['zipcode_category'] = df['zipcode_category'].astype('category')

# Add ordered category
df['zipcode_ordered'] = df['zipcode_category']

# Setup the ordering
df.zipcode_ordered.cat.set_categories(
    new_categories = [90211, 90210], ordered = True, inplace = True
)

# Output IDs
df['zipcode_ordered_id'] = df.zipcode_ordered.cat.codes
print(df)
#  zipcode_category zipcode_ordered  zipcode_ordered_id
#            90210           90210                   1
#            90211           90211                   0

More details on setting ordered categories can be found at the pandas website:

https://pandas.pydata.org/pandas-docs/stable/user_guide/categorical.html#sorting-and-order

To add that using Jquery:

$('#commentForm').submit(function(){ //listen for submit event
    $.each(params, function(i,param){
        $('<input />').attr('type', 'hidden')
            .attr('name', param.name)
            .attr('value', param.value)
            .appendTo('#commentForm');
    });

    return true;
}); 

You can do :

document.forms["loginForm"].submit()

But this won't call the onclick action of your button, so you will need to call it by hand.

Be aware that you must use the name of your form and not the id to access it.

Here is another approach.

class orbisius_custom_string {
    /**
     * The reverse of nl2br. Handles <br/> <br/> <br />
     * usage: orbisius_custom_string::br2nl('Your buffer goes here ...');
     * @param str $buff
     * @return str
     * @author Slavi Marinov | http://orbisius.com
     */
    public static function br2nl($buff = '') {
        $buff = preg_replace('#<br[/\s]*>#si', "\n", $buff);
        $buff = trim($buff);

        return $buff;
    }
}

For those who are not using JPA and instead prefer to exclude the entityManagerFactory and use Spring Data JDBC or Spring JDBC can exclude the bean to avoid the exception

@SpringBootApplication(exclude = {HibernateJpaAutoConfiguration.class})

Simple vanilla JS code sample:

document.addEventListener('touchstart', handleTouchStart, false);        
document.addEventListener('touchmove', handleTouchMove, false);

var xDown = null;                                                        
var yDown = null;

function getTouches(evt) {
  return evt.touches ||             // browser API
         evt.originalEvent.touches; // jQuery
}                                                     

function handleTouchStart(evt) {
    const firstTouch = getTouches(evt)[0];                                      
    xDown = firstTouch.clientX;                                      
    yDown = firstTouch.clientY;                                      
};                                                

function handleTouchMove(evt) {
    if ( ! xDown || ! yDown ) {
        return;
    }

    var xUp = evt.touches[0].clientX;                                    
    var yUp = evt.touches[0].clientY;

    var xDiff = xDown - xUp;
    var yDiff = yDown - yUp;

    if ( Math.abs( xDiff ) > Math.abs( yDiff ) ) {/*most significant*/
        if ( xDiff > 0 ) {
            /* left swipe */ 
        } else {
            /* right swipe */
        }                       
    } else {
        if ( yDiff > 0 ) {
            /* up swipe */ 
        } else { 
            /* down swipe */
        }                                                                 
    }
    /* reset values */
    xDown = null;
    yDown = null;                                             
};

Tested in Android.

Use java -cp myjar.jar com.mypackage.myClass.

1. If the class is not in a package then simply java -cp myjar.jar myClass.

2. If you are not within the directory where myJar.jar is located, then you can do:

   1. On Unix or Linux platforms:

      java -cp /location_of_jar/myjar.jar com.mypackage.myClass

   2. On Windows:

      java -cp c:\location_of_jar\myjar.jar com.mypackage.myClass

You have the word 'document' in a string. Change:

$('document').keypress(function(e){

to

$(document).keypress(function(e){

I just found this blog entry and want to share it here with you because I think it is the best way to do it and it is so easy.

http://fabiorehm.com/blog/2014/09/11/running-gui-apps-with-docker/

PROS:
+ no x server stuff in the docker container
+ no vnc client/server needed
+ no ssh with x forwarding
+ much smaller docker containers

CONS:
- using x on the host (not meant for secure-sandboxing)

in case the link will fail someday I have put the most important part here:
dockerfile:

FROM ubuntu:14.04

RUN apt-get update && apt-get install -y firefox

# Replace 1000 with your user / group id
RUN export uid=1000 gid=1000 && \
    mkdir -p /home/developer && \
    echo "developer:x:${uid}:${gid}:Developer,,,:/home/developer:/bin/bash" >> /etc/passwd && \
    echo "developer:x:${uid}:" >> /etc/group && \
    echo "developer ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/developer && \
    chmod 0440 /etc/sudoers.d/developer && \
    chown ${uid}:${gid} -R /home/developer

USER developer
ENV HOME /home/developer
CMD /usr/bin/firefox

build the image:

docker build -t firefox .

and the run command:

docker run -ti --rm \
   -e DISPLAY=$DISPLAY \
   -v /tmp/.X11-unix:/tmp/.X11-unix \
   firefox

of course you can also do this in the run command with sh -c "echo script-here"

HINT: for audio take a look at: https://stackoverflow.com/a/28985715/2835523

Recently, I have seen this problem too. Below, you have my solution:

1. ping github.com, if ping failed. it is DNS error.
2. sudo vim /etc/resolv.conf, the add: nameserver 8.8.8.8 nameserver 8.8.4.4

Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart or fix it up

I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):

ssh -T [email protected]

Upon receiving a successful response, I could fetch/push to the repo with ssh.

I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.

Brett - are you aware that getElementyByClassName support from IE 5.5 to 8 is not there according to quirksmode?. You would be better off following this pattern if you care about cross-browser compatibility:

• Get container element by ID.
• Get needed child elements by tag name.
• Iterate over children, test for matching className property.
• elements[i].parentNode.removeChild(elements[i]) like the other guys said.

Quick example:

var cells = document.getElementById("myTable").getElementsByTagName("td");
var len = cells.length;
for(var i = 0; i < len; i++) {
    if(cells[i].className.toLowerCase() == "column") {
        cells[i].parentNode.removeChild(cells[i]);
    }
}

Here's a quick demo.

EDIT: Here is the fixed version, specific to your markup:

var col_wrapper = document.getElementById("columns").getElementsByTagName("div");

var elementsToRemove = [];
for (var i = 0; i < col_wrapper.length; i++) {
    if (col_wrapper[i].className.toLowerCase() == "column") {
        elementsToRemove.push(col_wrapper[i]);
    }
}
for(var i = 0; i < elementsToRemove.length; i++) {
    elementsToRemove[i].parentNode.removeChild(elementsToRemove[i]);
}

The problem was my fault; when you remove an element from the resulting array of elements, the length changes, so one element gets skipped at each iteration. The solution is to store a reference to each element in a temporary array, then subsequently loop over those, removing each one from the DOM.

Try it here.

In Python 3, this worked with me

import urllib

urllib.parse.quote(query)

Try using the css properties min and max as a workaround

For example:

width: min(50vw, 200px);

means the width will be the smallest of the two values.

width: max(50vw, 200px);

means the width will be the larger of the two values.

Using DateTime::createFromFormat:

$format = "d_m_y";
$date1  = \DateTime::createFromFormat($format, "03_01_12");
$date2  = \DateTime::createFromFormat($format, "31_12_11");

var_dump($date1 > $date2);

What i did is that , i created a new certificate for distribution form my Mac computer and gave signing identity from this Mac computer as well, and thats it

How about

# pattern is by finding a set of numbers in the start and capturing them
as.numeric(gsub("([0-9]+).*$", "\\1", years))

or

# pattern is to just remove _years_old
as.numeric(gsub(" years old", "", years))

or

# split by space, get the element in first index
as.numeric(sapply(strsplit(years, " "), "[[", 1))

If you have any function associated to list ,when you make the splice function, the association is deleted too. My solution:

$scope.remove = function() {
    var oldList = $scope.items;
    $scope.items = [];

    angular.forEach(oldList, function(x) {
        if (! x.done) $scope.items.push( { [ DATA OF EACH ITEM USING oldList(x) ] });
    });
};

The list param is named items. The param x.done indicate if the item will be deleted.

I am using this method (Works in IE9+), although it will not parse <td> or some other invalid direct childs of body:

function stringToEl(string) {
    var parser = new DOMParser(),
        content = 'text/html',
        DOM = parser.parseFromString(string, content);

    // return element
    return DOM.body.childNodes[0];
}

stringToEl('<li>text</li>'); //OUTPUT: <li>text</li>

By default . (any character) does not match newline characters.

This means you can simply match zero or more of any character then append the end tag.

Find: <li><a href="#">.* Replace: $0</a>

If the binary is something more than a dll or something that can be edited directly like an image, or a blend file (and you don't need to trash/select one file or the other) a real merge would be some like:

I suggest searching for a diff tool oriented to what are your binary file, for example, there are some free ones for image files for example

• npm install -g imagediff IIRC from https://github.com/uber/image-diff
• or python https://github.com/kaikuehne/mirror.git
• there are others out there

and compare them.

If there is no diff tool out there for comparing your files, then if you have the original generator of the bin file (that is, there exist an editor for it... like blender 3d, you can then manually inspect those files, also see the logs, and ask the other person what you should include) and do output of the files with https://git-scm.com/book/es/v2/Git-Tools-Advanced-Merging#_manual_remerge

$ git show :1:hello.blend > hello.common.blend
$ git show :2:hello.blend > hello.ours.blend
$ git show :3:hello.blend > hello.theirs.blend

PowerShell 3 has the $PSScriptRoot automatic variable:

Contains the directory from which a script is being run.

In Windows PowerShell 2.0, this variable is valid only in script modules (.psm1). Beginning in Windows PowerShell 3.0, it is valid in all scripts.

Don't be fooled by the poor wording. PSScriptRoot is the directory of the current file.

In PowerShell 2, you can calculate the value of $PSScriptRoot yourself:

# PowerShell v2
$PSScriptRoot = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition

The easiest way would be

Section = 'Sec_' + Section

But for efficiency, see: https://waymoot.org/home/python_string/

I ran into this problem the other day: I had some classes full of static methods but I wanted to use inheritance and virtual methods and reduce code repetition. My solution was:

Instead of using static methods, use a singleton with virtual methods.

In other words, each class should contain a static method that you call to get a pointer to a single, shared instance of the class. You can make the true constructors private or protected so that outside code can't misuse it by creating additional instances.

In practice, using a singleton is a lot like using static methods except that you can take advantage of inheritance and virtual methods.

Suppose we have this dummy collection:

{ "_id" : ObjectId("5ea53fedaa79db20d4e14284"), "item" : "planner", "qty" : 75 }

simply use:

db.inventory.deleteOne({ _id: ObjectId("5ea53fedaa79db20d4e14284") })

it will be deleted with this as a response:

{ "acknowledged" : true, "deletedCount" : 1 }

Thats it.

In my case the problem was that there was a view with the same name as my table, so I had to drop the view to allow the import to continue.

drop view `my-view-that-has-same-name-as-table`;

An automated solution that worked for me is to replace the normal drop table with this sed during the dump to also drop any views that might exist:

mysqldump my-db \
| sed -E 's/^DROP TABLE IF EXISTS(.+)$/\0 DROP VIEW IF EXISTS\1/g' \
| mysql my-other-db

Or if you would rather print to a file for backup

mysqldump my-db \
| sed -E 's/^DROP TABLE IF EXISTS(.+)$/\0 DROP VIEW IF EXISTS\1/g' \
> my-db.dump.sql

Or if you received the dumped file and you are importing it to your db

cat my-db.dump.sql \
| sed -E 's/^DROP TABLE IF EXISTS(.+)$/\0 DROP VIEW IF EXISTS\1/g' \
| mysql my-other-db

You get the idea

Note: it is important that you add the ^ at the beginning of the replacement regex, because there are other types of DROP TABLE IF EXISTS commands in dumps that you don't want to touch.

You go from having something like this:

--
-- Table structure for table `my_table`
--

DROP TABLE IF EXISTS `my_table`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `my_table` (
...

To having something like this:

--
-- Table structure for table `my_table`
--

DROP TABLE IF EXISTS `my_table`; DROP VIEW IF EXISTS `my_table`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `my_table` (
...

Try removing "package-lock.json" and running "npm install && npm update", it'll install the latest version and clear all errors.

Python resolves your variables with -- generally -- three namespaces available.

At any time during execution, there are at least three nested scopes whose namespaces are directly accessible: the innermost scope, which is searched first, contains the local names; the namespaces of any enclosing functions, which are searched starting with the nearest enclosing scope; the middle scope, searched next, contains the current module's global names; and the outermost scope (searched last) is the namespace containing built-in names.

There are two functions: globals and locals which show you the contents two of these namespaces.

Namespaces are created by packages, modules, classes, object construction and functions. There aren't any other flavors of namespaces.

In this case, the call to a function named x has to be resolved in the local name space or the global namespace.

Local in this case, is the body of the method function Foo.spam.

Global is -- well -- global.

The rule is to search the nested local spaces created by method functions (and nested function definitions), then search global. That's it.

There are no other scopes. The for statement (and other compound statements like if and try) don't create new nested scopes. Only definitions (packages, modules, functions, classes and object instances.)

Inside a class definition, the names are part of the class namespace. code2, for instance, must be qualified by the class name. Generally Foo.code2. However, self.code2 will also work because Python objects look at the containing class as a fall-back.

An object (an instance of a class) has instance variables. These names are in the object's namespace. They must be qualified by the object. (variable.instance.)

From within a class method, you have locals and globals. You say self.variable to pick the instance as the namespace. You'll note that self is an argument to every class member function, making it part of the local namespace.

See Python Scope Rules, Python Scope, Variable Scope.

Try this may work..

<html>
   <?php $num = 1; ?>
   <div id="Count"><?php echo $num; ?></div>
   <input type = "button" name = "lol" value = "Click to increment" onclick = "Inc()">
   <br>
   <script>
   function Inc() {
       i = parseInt(document.getElementById('Count').innerHTML);
       document.getElementById('Count').innerHTML = i+1;
   }
   </script>
</html>

DateTime.Now.ToString("dd/MM/yyyy");

You don't have to have a method for that. You could create a property like this instead:

class SalesPerson
{
    string firstName, lastName;
    public string FirstName { get { return firstName; } set { firstName = value; } }
    public string LastName { get { return lastName; } set { lastName = value; } }
    public string FullName { get { return this.FirstName + " " + this.LastName; } }
}

The class could even be shortened to:

class SalesPerson
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string FullName { 
       get { return this.FirstName + " " + this.LastName; } 
    }
}

The property could then be accessed like any other property:

class Program
{
    static void Main(string[] args)
    {
        SalesPerson x = new SalesPerson("John", "Doe");
        Console.WriteLine(x.FullName); // Will print John Doe
    }
}

<% @images.each_with_index do |page, index| %>

<% end %>

<a href="/fruits/index.html">Back to Fruits List</a>

remove autofocus edittext android

It's working for me

Edit In the link they suggest to use LinearLayout, but simple View will work

<View
    android:id="@+id/focus_thief"
    android:layout_width="1dp"
    android:layout_height="1dp"
    android:focusable="true"
    android:focusableInTouchMode="true" />

Then if this "thief" is placed at the top of the layout (to be first focusable item) calls to clearFocus() will work.

In my view page:

<p:dataTable  ...>
<p:column>
<p:commandLink actionListener="#{inquirySOController.viewDetail}" 
               process="@this" update=":mainform:dialog_content"
           oncomplete="dlg2.show()">
    <h:graphicImage library="images" name="view.png"/>
    <f:param name="trxNo" value="#{item.map['trxNo']}"/>
</p:commandLink>
</p:column>
</p:dataTable>

backing bean

 public void viewDetail(ActionEvent e) {

    String trxNo = getFacesContext().getRequestParameterMap().get("trxNo");

    for (DTO item : list) {
        if (item.get("trxNo").toString().equals(trxNo)) {
            System.out.println(trxNo);
            setSelectedItem(item);
            break;
        }
    }
}

Solution

You want to (1) create stdout output in one process (like echo '…') and (2) redirect that output to stdin input of another process but (3) without the use of the bash pipe mechanism. Here's a solution that matches all three conditions:

/my/bash/script < <(echo 'This string will be sent to stdin.')

The < is normal input redirection for stdin. The <(…) is bash process substitution. Roughly it creates a /dev/fd/… file with the output of the substituting command and passes that filename in place of the <(…), resulting here for example in script < /dev/fd/123. For details, see this answer.

Comparison with other solutions

• A one-line heredoc sent to stdin script <<< 'string' only allows to send static strings, not the output of other commands.

• Process substitution alone, such as in diff <(ls /bin) <(ls /usr/bin), does not send anything to stdin. Instead, the process output is saved into a file, and its path is passed as a command line argument. For the above example, this is equivalent to diff /dev/fd/10 /dev/fd/11, a command where diff receives no input from stdin.

Use cases

I like that, unlike the pipe mechanism, the < <(…) mechanism allows to put the command first and all input after it, as is the standard for input from command line options.

However, beyond commandline aesthetics, there are some cases where a pipe mechanism cannot be used. For example, when a certain command has to be provided as argument to another command, such as in this example with sshpass.

Try this, working fine -

$array = json_decode(json_encode($array), true);

java.time

You should use java.time classes with Java 8 and later. To use java.time, add:

import java.time.* ;

Below is an example, how you can format date.

DateTimeFormatter format = DateTimeFormatter.ofPattern("dd-MMM-yyyy");
String date = "15-Oct-2018";
LocalDate localDate = LocalDate.parse(date, formatter);

System.out.println(localDate); 
System.out.println(formatter.format(localDate));

The best method is given in the docs

$('#myModal').on('shown.bs.modal', function () {
  // will only come inside after the modal is shown
});

for more info refer http://getbootstrap.com/javascript/#modals

You can simply do the following inside your TR loop:

$(this).find('td').each (function() {
  // do your cool stuff
});                          

In C++ you can use EscapeXML ATL API. This is the correct way of handling special chars ...

All modern browsers (tested with Chrome 4, Firefox 3.5, IE8, Opera 10 and Safari 4) will always request a favicon.ico unless you've specified a shortcut icon via <link>. So if you don't explicitly specify one, it's best to always have a favicon.ico file, to avoid a 404. Yahoo! suggests you make it small and cacheable.

And you don't have to go for a PNG just for the alpha transparency either. ICO files support alpha transparency just fine (i.e. 32-bit color), though hardly any tools allow you to create them. I regularly use Dynamic Drive's FavIcon Generator to create favicon.ico files with alpha transparency. It's the only online tool I know of that can do it.

There's also a free Photoshop plug-in that can create them.

in this link i mentioned before on the comment, read this part :

A "fetch" join allows associations or collections of values to be initialized along with their parent objects using a single select. This is particularly useful in the case of a collection. It effectively overrides the outer join and lazy declarations of the mapping file for associations and collections.

this "JOIN FETCH" will have it's effect if you have (fetch = FetchType.LAZY) property for a collection inside entity(example bellow).

And it is only effect the method of "when the query should happen". And you must also know this:

hibernate have two orthogonal notions : when is the association fetched and how is it fetched. It is important that you do not confuse them. We use fetch to tune performance. We can use lazy to define a contract for what data is always available in any detached instance of a particular class.

when is the association fetched --> your "FETCH" type

how is it fetched --> Join/select/Subselect/Batch

In your case, FETCH will only have it's effect if you have department as a set inside Employee, something like this in the entity:

@OneToMany(fetch = FetchType.LAZY)
private Set<Department> department;

when you use

FROM Employee emp
JOIN FETCH emp.department dep

you will get emp and emp.dep. when you didnt use fetch you can still get emp.dep but hibernate will processing another select to the database to get that set of department.

so its just a matter of performance tuning, about you want to get all result(you need it or not) in a single query(eager fetching), or you want to query it latter when you need it(lazy fetching).

Use eager fetching when you need to get small data with one select(one big query). Or use lazy fetching to query what you need latter(many smaller query).

use fetch when :

• no large unneeded collection/set inside that entity you about to get

• communication from application server to database server too far and need long time

• you may need that collection latter when you don't have the access to it(outside of the transactional method/class)

From http://www.praetoriate.com/oracle_tips_upserts.htm:

"In Oracle9i, an UPSERT can accomplish this task in a single statement:"

Beware of the use of push method, if you don't use indexes, it won't work!

var main2dArray: Things[][] = []

main2dArray.push(someTmp1dArray)
main2dArray.push(someOtherTmp1dArray)

gives only a 1 line array!

use

main2dArray[0] = someTmp1dArray
main2dArray[1] = someOtherTmp1dArray

to get your 2d array working!!!

Other beware! foreach doesn't seem to work with 2d arrays!

Working example:

    Intent intent = new Intent(ctx, HomeActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder b = new NotificationCompat.Builder(ctx);

    b.setAutoCancel(true)
     .setDefaults(Notification.DEFAULT_ALL)
     .setWhen(System.currentTimeMillis())         
     .setSmallIcon(R.drawable.ic_launcher)
     .setTicker("Hearty365")            
     .setContentTitle("Default notification")
     .setContentText("Lorem ipsum dolor sit amet, consectetur adipiscing elit.")
     .setDefaults(Notification.DEFAULT_LIGHTS| Notification.DEFAULT_SOUND)
     .setContentIntent(contentIntent)
     .setContentInfo("Info");


    NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(1, b.build());

You can't without an iteration.

Option 1

Carnet findCarnet(String codeIsIn) {
    for(Carnet carnet : listCarnet) {
        if(carnet.getCodeIsIn().equals(codeIsIn)) {
            return carnet;
        }
    }
    return null;
}

Option 2

Override the equals() method of Carnet.

Option 3

Storing your List as a Map instead, using codeIsIn as the key:

HashMap<String, Carnet> carnets = new HashMap<>();
// setting map
Carnet carnet = carnets.get(codeIsIn);

put anyfile on the directories you wanted to find, in this case, place 'root' at public_html

/home/user/public_html/root <- note that 'root' is not a folder (you can use root.txt if u want)

And use this function

function findThis($get){
    $d = '';
    for($i = 0; $i < 20; $i++){//this will try 20 times recursively on upper folder
        if(file_exists($d.$get)){
            return $d;
        }else{
            $d.="../";
        }
    }
}

and get the value by calling it

$pathToRoot = findThis('root');

And it will return, for example the the dir of php script is

/home/user/public_html/test/another-dir/test.php

so the $pathToRoot will be

$pathToRoot => "../../../"

Is this the one you want??

If this is your detail.html I don't see where do you load detail.js? Maybe this

<script src="js/index.js"></script>

should be this

<script src="js/detail.js"></script>

?

my 2 cents:

$('#theDiv').prepend($('<img>',{id:'theImg',src:'theImg.png'}))

Here is how I would do it if working with a large number of "to remove" values that would take a long time to manually remove.

• -Put Original List in Column A -Put To Remove list in Column B -Select both columns, then "Conditional Formatting"
  -Select "Hightlight Cells Rules" --> "Duplicate Values"
  -The duplicates should be hightlighted in both columns
  -Then select Column A and then "Sort & Filter" ---> "Custom Sort"
  -In the dialog box that appears, select the middle option "Sort On" and pick "Cell Color"
  -Then select the next option "Sort Order" and choose "No Cell Color" "On bottom"
  -All the highlighted cells should be at the top of the list. -Select all the highlighted cells by scrolling down the list, then click delete.

It does not work in uniform way in all browsers. I went to to: http://www.w3schools.com/html/tryit.asp?filename=tryhtml_pulpitimage and added style for zoom and -moz-transform. I ran the same code on firefox, IE and chrome and got 3 different results.

<html>
<style>
body{zoom:3;-moz-transform: scale(3);}
</style>
<body>

<h2>Norwegian Mountain Trip</h2>
<img border="0" src="/images/pulpit.jpg" alt="Pulpit rock"  />

</body>
</html>

If you actually know the text you are going to replace you could use

$('#one').contents(':contains("Hi I am text")')[0].nodeValue = '"Hi I am replace"';

http://jsfiddle.net/5rWwh/

Or

$('#one').contents(':not(*)')[1].nodeValue = '"Hi I am replace"';

$('#one').contents(':not(*)') selects non-element child nodes in this case text nodes and the second node is the one we want to replace.

If you are compiling linux kernel. For example, if you want to disable the warning that is "unused-but-set-variable" been treated as error. You can add a statement:

KBUILD_CFLAGS += $(call cc-option,-Wno-error=unused-but-set-variable,)

in your Makefile

[]byte is a slice (similar to a substring) of all or part of a byte array. Think of the slice as a value structure with a hidden pointer field for the system to locate and access all or part of an array (the slice), plus fields for the length and capacity of the slice, which you can access using the len() and cap() functions.

Here's a working starter kit for you, which reads and prints a binary file; you will need to change the inName literal value to refer to a small file on your system.

package main
import (
    "fmt";
    "os";
)
func main()
{
    inName := "file-rw.bin";
    inPerm :=  0666;
    inFile, inErr := os.Open(inName, os.O_RDONLY, inPerm);
    if inErr == nil {
        inBufLen := 16;
        inBuf := make([]byte, inBufLen);
        n, inErr := inFile.Read(inBuf);
        for inErr == nil {
            fmt.Println(n, inBuf[0:n]);
            n, inErr = inFile.Read(inBuf);
        }
    }
    inErr = inFile.Close();
}

I had to go through this process myself and chose a different way that I think is better in the long run.

I installed homebrew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

then:

brew doctor

The last step gives you some warnings and errors that you have to resolve. One of those will be to download and install the Mac OS X command-line tools.

then:

brew install python3

This gave me python3 and pip3 in my path.

You can check your respone content, just console.log it and you will see whitch property have a status code. If you do not understand jsons, please refer to the video: https://www.youtube.com/watch?v=Bv_5Zv5c-Ts

It explains very basic knowledge that let you feel more comfortable with javascript.

You can do it with shorter version of ajax request, please see code above:

$.get("example.url.com", function(data) {
                console.log(data);
            }).done(function() {
               // TO DO ON DONE
            }).fail(function(data, textStatus, xhr) {
                 //This shows status code eg. 403
                 console.log("error", data.status);
                 //This shows status message eg. Forbidden
                 console.log("STATUS: "+xhr);
            }).always(function() {
                 //TO-DO after fail/done request.
                 console.log("ended");
            });

Example console output:

The simplest solution is to use a derived table:

Select Count(*)
From    (
        Select ...
        From TempTable
        Group By column_1, column_2, column_3, column_4
        ) As Z

Another solution is to use a Count Distinct:

Select ...
    , ( Select Count( Distinct column_1, column_2, column_3, column_4 )
        From TempTable ) As CountOfItems
From TempTable
Group By column_1, column_2, column_3, column_4

Try

let s=`This is man._x000D_
_x000D_
     Man like dog._x000D_
     Man like to drink._x000D_
_x000D_
     Man is the king.`;_x000D_
     _x000D_
msg.innerHTML = s.replace(/\n/g,"<br />");

<div id="msg"></div>

Extending Yoni Gibbs's answer, if you are in an android project using retrofit and configure serialization with Jackson you can do these things in order to deserialization works as expected with kotlin's data class.

In your build gradle import:

implementation "com.fasterxml.jackson.module:jackson-module-kotlin:2.11.+"

Then, your implementation of retrofit:

val serverURL = "http://localhost:8080/api/v1"

val objectMapper = ObjectMapper()
objectMapper.registerModule(KotlinModule())
//Only if you are using Java 8's Time API too, require jackson-datatype-jsr310
objectMapper.registerModule(JavaTimeModule())

Retrofit.Builder()
    .baseUrl(serverURL)
    .client(

Hmm, I see that Process Explorer can do it, although its graphs are not too convenient. Still looking for alternative / better ways to do it.

NO,but there are some other options to implement default value. There are some good blog posts on the subject, but here are some specific examples.

// Both parameters are optional, use empty string for default value
func Concat1(a string, b int) string {
  if a == "" {
    a = "default-a"
  }
  if b == 0 {
    b = 5
  }

  return fmt.Sprintf("%s%d", a, b)
}

// a is required, b is optional.
// Only the first value in b_optional will be used.
func Concat2(a string, b_optional ...int) string {
  b := 5
  if len(b_optional) > 0 {
    b = b_optional[0]
  }

  return fmt.Sprintf("%s%d", a, b)
}

// A declarative default value syntax
// Empty values will be replaced with defaults
type Parameters struct {
  A string `default:"default-a"` // this only works with strings
  B string // default is 5
}

func Concat3(prm Parameters) string {
  typ := reflect.TypeOf(prm)

  if prm.A == "" {
    f, _ := typ.FieldByName("A")
    prm.A = f.Tag.Get("default")
  }

  if prm.B == 0 {
    prm.B = 5
  }

  return fmt.Sprintf("%s%d", prm.A, prm.B)
}

func Concat4(args ...interface{}) string {
  a := "default-a"
  b := 5

  for _, arg := range args {
    switch t := arg.(type) {
      case string:
        a = t
      case int:
        b = t
      default:
        panic("Unknown argument")
    }
  }

  return fmt.Sprintf("%s%d", a, b)
}

If you want to manually add support to your site, you can just add the following to your web.config in the system.webServer section:

<staticContent>
    <mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>

This will add a "local" configuration under IIS. This does not work in IIS6, but does work in IIS7 and newer.

After way too much research, trial and error I found a way that seems to works fine and doesn't require to manually re-set the font size manually on the children elements, allowing me to have a standardized em font size across the whole doc.

In Firefox this is fairly simple, just set word-spacing: -1em on the parent element. For some reason, Chrome ignore this (and as far as I tested, it ignores the word spacing regardless of the value). So besides this I add letter-spacing: -.31em to the parent and letter-spacing: normal to the children. This fraction of an em is the size of the space ONLY IF your em size is standardized. Firefox, in turn, ignores negative values for letter-spacing, so it won't add it to the word spacing.

I tested this on Firefox 13 (win/ubuntu, 14 on android), Google Chrome 20 (win/ubuntu), Android Browser on ICS 4.0.4 and IE 9. And I'm tempted to say this may also work on Safari, but I don't really know...

Depending on your platform you may have usleep or nanosleep available. usleep is deprecated and has been deleted from the most recent POSIX standard; nanosleep is preferred.

You can also login to the redis-cli and use the MONITOR command to see what queries are happening against Redis.

Why not just use a regular for loop?

{
    ListViewItem lvi = listView.Items[i];

Some Google services do not like to be used to much. Quite recently my account was locked because of script, which was sending two e-mails per second to the same user. Google considered it as a spam. So using sleep here is also justified to prevent such situations.

Make sure that the node server to provide the bundle is running in the background. To run start the server use npm start or react-native start and keep the tab open during development

just one small additional example

requested time in miliseconds

    // ms2time( (microtime(true) - ( time() - rand(0,1000000) ) ) );
    // return array
    function ms2time($ms){
        $return = array();
        // ms
        $return['ms'] = (int) number_format( ($ms - (int) $ms), 2, '', '');
        $seconds = (int) $ms;
        unset($ms);

        if ($seconds%60 > 0){
            $return['s'] = $seconds%60;
        } else {
            $return['s'] = 0;
        }

        if ( ($minutes = intval($seconds/60))){
            $return['m'] = $minutes;
        }

        if (isset($return['m'])){
            $return['h'] = intval($return['m'] / 60);
            $return['m']  = $return['m'] % 60; 
        }


        if (isset($return['h'])){
            $return['d'] = intval($return['h'] / 24);
            $return['h']  = $return['h'] % 24; 
        }

        if (isset($return['d']))
            $return['mo'] = intval($return['d'] / 30);

        foreach($return as $k=>$v){
            if ($v == 0)
                unset($return[$k]);
        }

        return $return;

        $array = array(
            'ms' => 'ms',

            'm'  => 'minutes',
            'h'  => 'hours',

            foreach($return as $key=>$data){
                $return[$key] = $data .' '.$array[$key];
            }

        }
        return implode(" ", array_reverse($return));
    }

You can use the Logical NOT ! operator:

if (!$(this).parent().next().is('ul')){

Or equivalently (see comments below):

if (! ($(this).parent().next().is('ul'))){

For more information, see the Logical Operators section of the MDN docs.

As mentioned in several answers already that have been already given, you can use ToShorDateString():

DateTime.Now.ToShortDateString();

However, you may be a bit blocked if you also want to use the culture as a parameter. In this case you can use the ToString() method with the "d" format:

DateTime.Now.ToString("d", CultureInfo.GetCultureInfo("en-US"))

If all you want to do is enumerate them, use the IEnumerable.

Beware, though, that changing the original collection being enumerated is a dangerous operation - in this case, you will want to ToList first. This will create a new list element for each element in memory, enumerating the IEnumerable and is thus less performant if you only enumerate once - but safer and sometimes the List methods are handy (for instance in random access).

This is the way I've assigned names to individual VMs. Change YOURNAMEHERE to your desired name.

Contents of Vagrantfile:

Vagrant.configure("2") do |config|

  # Every Vagrant virtual environment requires a box to build off of.
  config.vm.box = "precise32"

  # The url from where the 'config.vm.box' box will be fetched if it
  # doesn't already exist on the user's system.
  config.vm.box_url = "http://files.vagrantup.com/precise32.box"

  config.vm.define :YOURNAMEHERE do |t|
  end

end

Terminal output:

$ vagrant status
Current machine states:

YOURNAMEHERE             not created (virtualbox)

inArray returns the index of the element in the array, not a boolean indicating if the item exists in the array. If the element was not found, -1 will be returned.

So, to check if an item is in the array, use:

if(jQuery.inArray("test", myarray) !== -1)

I was also following the instructions on http://developer.android.com/training/basics/actionbar/setting-up.html

and even though I did everything in the tutorial, as soon as "extends Action" is changed to "extends ActionBarActivity" all sorts of errors appear in Eclipse, including the "ActionBarActivitycannot be resolved to a type"

None of the above solutions worked for me, but what did work is adding this line to the top:

import android.support.v7.app.ActionBarActivity;

Insert else update both

public void InsertUpdateData()
{
//Here TestEntities is the class which is given from "Save entity connection setting in web.config"
TestEntities context = new TestEntities();

var query = from data in context.Employee
            orderby data.name
            select data;

foreach (Employee details in query)
{
    if (details.id == 1)
    {
        //Assign the new values to name whose id is 1
        details.name = "Sanjay";
        details. Surname="Desai";
        details.address=" Desiwadi";
    }
    else if(query==null)
    {
        details.name="Sharad";
        details.surname=" Chougale ";
        details.address=" Gargoti";
    }
}

//Save the changes back to database.
context.SaveChanges();
}

This is the easiest way in my opinion:

RaisedButton(
  child: Text("PRESS BUTTON"),
  onPressed: booleanCondition
    ? () => myTapCallback()
    : null
)

imageView.setImageDrawable(getResources().getDrawable(R.drawable.my_drawable));

First add the collections and then apply lookup on these collections. Don't use $unwind as unwind will simply separate all the documents of each collections. So apply simple lookup and then use $project for projection. Here is mongoDB query:

db.userInfo.aggregate([
    {
        $lookup: {
           from: "userRole",
           localField: "userId",
           foreignField: "userId",
           as: "userRole"
        }
    },
    {
        $lookup: {
            from: "userInfo",
            localField: "userId",
            foreignField: "userId",
            as: "userInfo"
        }
    },
    {$project: {
        "_id":0,
        "userRole._id":0,
        "userInfo._id":0
        }
        } ])

Here is the output:

/* 1 */ {
    "userId" : "AD",
    "phone" : "0000000000",
    "userRole" : [ 
        {
            "userId" : "AD",
            "role" : "admin"
        }
    ],
    "userInfo" : [ 
        {
            "userId" : "AD",
            "phone" : "0000000000"
        }
    ] }

Thanks.

please check if code below would work for you; it iterates through cells of the datagris's first column and checks if cell content equals to the textbox.text value and selects the row.

for (int i = 0; i < dataGrid.Items.Count; i++)
{
    DataGridRow row = (DataGridRow)dataGrid.ItemContainerGenerator.ContainerFromIndex(i);
    TextBlock cellContent = dataGrid.Columns[0].GetCellContent(row) as TextBlock;
    if (cellContent != null && cellContent.Text.Equals(textBox1.Text))
    {
        object item = dataGrid.Items[i];
        dataGrid.SelectedItem = item;
        dataGrid.ScrollIntoView(item);
        row.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
        break;
    }
}

hope this helps, regards

You can simply get the text in editText by applying below code:

EditText editText=(EditText)findViewById(R.id.vnosZadeve);
String text=editText.getText().toString();

then you can toast string text!

Happy coding!

There are basically 3 approaches to that: not exists, not in and left join / is null.

LEFT JOIN with IS NULL

SELECT  l.*
FROM    t_left l
LEFT JOIN
        t_right r
ON      r.value = l.value
WHERE   r.value IS NULL

NOT IN

SELECT  l.*
FROM    t_left l
WHERE   l.value NOT IN
        (
        SELECT  value
        FROM    t_right r
        )

NOT EXISTS

SELECT  l.*
FROM    t_left l
WHERE   NOT EXISTS
        (
        SELECT  NULL
        FROM    t_right r
        WHERE   r.value = l.value
        )

Which one is better? The answer to this question might be better to be broken down to major specific RDBMS vendors. Generally speaking, one should avoid using select ... where ... in (select...) when the magnitude of number of records in the sub-query is unknown. Some vendors might limit the size. Oracle, for example, has a limit of 1,000. Best thing to do is to try all three and show the execution plan.

Specifically form PostgreSQL, execution plan of NOT EXISTS and LEFT JOIN / IS NULL are the same. I personally prefer the NOT EXISTS option because it shows better the intent. After all the semantic is that you want to find records in A that its pk do not exist in B.

Old but still gold, specific to PostgreSQL though: https://explainextended.com/2009/09/16/not-in-vs-not-exists-vs-left-join-is-null-postgresql/

My company has about 24million images come in from manufacturers every month. I was looking for a fast solution to ensure that the images we upload to our catalog are new images.

I want to say that I have searched the internet far and wide to attempt to find an ideal solution. I even developed my own edge detection algorithm.
I have evaluated speed and accuracy of multiple models. My images, which have white backgrounds, work extremely well with phashing. Like redcalx said, I recommend phash or ahash. DO NOT use MD5 Hashing or anyother cryptographic hashes. Unless, you want only EXACT image matches. Any resizing or manipulation that occurs between images will yield a different hash.

For phash/ahash, Check this out: imagehash

I wanted to extend *redcalx'*s post by posting my code and my accuracy.

What I do:

from PIL import Image
from PIL import ImageFilter
import imagehash

img1=Image.open(r"C:\yourlocation")
img2=Image.open(r"C:\yourlocation")
if img1.width<img2.width:
    img2=img2.resize((img1.width,img1.height))
else:
    img1=img1.resize((img2.width,img2.height))
img1=img1.filter(ImageFilter.BoxBlur(radius=3))
img2=img2.filter(ImageFilter.BoxBlur(radius=3))
phashvalue=imagehash.phash(img1)-imagehash.phash(img2)
ahashvalue=imagehash.average_hash(img1)-imagehash.average_hash(img2)
totalaccuracy=phashvalue+ahashvalue

Here are some of my results:

item1  item2  totalsimilarity
desk1  desk1       3
desk1  phone1     22
chair1 desk1      17
phone1 chair1     34

Hope this helps!

For me this code worked in JavaScript like a charm!

<%= session.getAttribute("variableName")%>

hope it helps...

Check if you have environment variable that could still define a proxy (picked up by curl, even if the git config does not include any proxy setting anymore):

HTTP_PROXY
HTTPS_PROXY

Users codelogic and harley are correct, but keep in mind if you know the string is an integer (for example, 545) you can call int("545") without first casting to float.

If your strings are in a list, you could use the map function as well.

>>> x = ["545.0", "545.6", "999.2"]
>>> map(float, x)
[545.0, 545.60000000000002, 999.20000000000005]
>>>

It is only good if they're all the same type.

Yes browsers clear all ref. for a window. So you have to search a ClassName of something on the main window or use cookies as Javascript homemade ref.

I have a radio on my project page. And then you turn on for the radio it´s starts in a popup window and i controlling the main window links on the main page and show status of playing and in FF it´s easy but in MSIE not so Easy at all. But it can be done.

• System properties are set on the Java command line using the -Dpropertyname=value syntax. They can also be added at runtime using System.setProperty(String key, String value) or via the various System.getProperties().load() methods.
  To get a specific system property you can use System.getProperty(String key) or System.getProperty(String key, String def).

• Environment variables are set in the OS, e.g. in Linux export HOME=/Users/myusername or on Windows SET WINDIR=C:\Windows etc, and, unlike properties, may not be set at runtime.
  To get a specific environment variable you can use System.getenv(String name).

Instantiating an interface gives a cleaner separation between your code and the implementation of threads, so I'd prefer to implement Runnable in this case.

Based on Perkins' amazing approach, I've updated and improved his "shortcut" for simple algebraic expressions (no functions or variables). Now it works on Python 3.6+ and avoids some pitfalls:

import re, sys

# Kept outside simple_eval() just for performance
_re_simple_eval = re.compile(rb'd([\x00-\xFF]+)S\x00')

def simple_eval(expr):
    c = compile(expr, 'userinput', 'eval')
    m = _re_simple_eval.fullmatch(c.co_code)
    if not m:
        raise ValueError(f"Not a simple algebraic expresion: {expr}")
    return c.co_consts[int.from_bytes(m.group(1), sys.byteorder)]

Testing, using some of the examples in other answers:

for expr, res in (
    ('2^4',                         6      ),
    ('2**4',                       16      ),
    ('1 + 2*3**(4^5) / (6 + -7)',  -5.0    ),
    ('7 + 9 * (2 << 2)',           79      ),
    ('6 // 2 + 0.0',                3.0    ),
    ('2+3',                         5      ),
    ('6+4/2*2',                    10.0    ),
    ('3+2.45/8',                    3.30625),
    ('3**3*3/3+3',                 30.0    ),
):
    result = simple_eval(expr)
    ok = (result == res and type(result) == type(res))
    print("{} {} = {}".format("OK!" if ok else "FAIL!", expr, result))

OK! 2^4 = 6
OK! 2**4 = 16
OK! 1 + 2*3**(4^5) / (6 + -7) = -5.0
OK! 7 + 9 * (2 << 2) = 79
OK! 6 // 2 + 0.0 = 3.0
OK! 2+3 = 5
OK! 6+4/2*2 = 10.0
OK! 3+2.45/8 = 3.30625
OK! 3**3*3/3+3 = 30.0

You need a reference to the class that contains the method you want to call. Let's say we have two classes, A and B. B has a method you want to call from A. Class A would look like this:

public class A
{
    B b; // A reference to B

    b = new B(); // Creating object of class B

    b.doSomething();  // Calling a method contained in class B from class A
}

B, which contains the doSomething() method would look like this:

public class B
{
    public void doSomething()
    {
        System.out.println("Look, I'm doing something in class B!");
    }
}

To add a bit of context to M.Ali's Answer you can convert a string to a uniqueidentifier using the following code

   SELECT CONVERT(uniqueidentifier,'DF215E10-8BD4-4401-B2DC-99BB03135F2E')

If that doesn't work check to make sure you have entered a valid GUID

If you for some reason want Application context in any class, not just those extending application/activity, maybe for some factory or helper classes. You can add the following singleton to your app.

public class GlobalAppContextSingleton {
    private static GlobalAppContextSingleton mInstance;
    private Context context;

    public static GlobalAppContextSingleton getInstance() {
        if (mInstance == null) mInstance = getSync();
        return mInstance;
    }

    private static synchronized GlobalAppContextSingleton getSync() {
        if (mInstance == null) mInstance = 
                new GlobalAppContextSingleton();
        return mInstance;
    }

    public void initialize(Context context) {
        this.context = context;
    }

    public Context getApplicationContext() {
        return context;
    }
}

then initialize it in your application class's onCreate with

GlobalAppContextSingleton.getInstance().initialize(this);

use it anywhere by calling

GlobalAppContextSingleton.getInstance().getApplicationContext()

I don't recommend this approach to anything but application context however. As it can cause memory leaks.

You could try this registry hack:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"DeadGWDetectDefault"=dword:00000001
"KeepAliveTime"=dword:00120000

If it works, just keep increasing the KeepAliveTime. It is currently set for 2 minutes.

This is going to sound stupid, but I tried all these solutions, running VS2010 on Windows 7. None of them worked except the renaming and building, which was VERY tedious to say the least. Eventually, I tracked down the culprit, and I find it hard to believe. But I was using the following code in AssemblyInfo.cs...

[assembly: AssemblyVersion("2.0.*")]

This is pretty common, but for some reason, changing the version to 2.0.0.0 made things work again. I don't know if it's a Windows 7 specific thing (I've only been using it for 3-4 weeks), or if it's random, or what, but it fixed it for me. I'm guessing that VS was keeping a handle on each file it generated, so it would know how to increment things? I'm really not sure and have never seen this happen before. But if someone else out there is also pulling their hair out, give it a try.

Try this shell script

DBENGINE='InnoDB' ;
DBUSER='your_db_user' ;
DBNAME='your_db_name' ;
DBHOST='your_db_host'
DBPASS='your_db_pass' ;
mysqldump --add-drop-table -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME > mtest.sql; mysql -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME -Nse "SHOW TABLES;" | while read TABLE ; do mysql -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME -Nse "ALTER TABLE $TABLE ENGINE=$DBENGINE;" ; done

for a in soup("p",{'id':'pagination'})[0]("a",{'href': True}):
        if createunicode(a.text) in ['<','<']:
            links.append(a.attrMap['href'])
        else:
            continue

It works for me.

Edit: in lieu of my own answer, this one is quite excellent: How to debug JavaScript/jQuery event bindings with Firebug (or similar tool)

Google Chromes developer tools has a search function built into the scripts section

If you are unfamiliar with this tool: (just in case)

• right click anywhere on a page (in chrome)
• click 'Inspect Element'
• click the 'Scripts' tab
• Search bar in the top right

Doing a quick search for the #ID should take you to the binding function eventually.

Ex: searching for #foo would take you to

$('#foo').click(function(){ alert('bar'); })

It's simple-

SELECT empname,
       empid,
       (SELECT COUNT (profileid)
          FROM profile
         WHERE profile.empid = employee.empid)
           AS number_of_profiles
  FROM employee;

It is even simpler when you use a table join like this:

  SELECT e.empname, e.empid, COUNT (p.profileid) AS number_of_profiles
    FROM employee e LEFT JOIN profile p ON e.empid = p.empid
GROUP BY e.empname, e.empid;

Explanation for the subquery:

Essentially, a subquery in a select gets a scalar value and passes it to the main query. A subquery in select is not allowed to pass more than one row and more than one column, which is a restriction. Here, we are passing a count to the main query, which, as we know, would always be only a number- a scalar value. If a value is not found, the subquery returns null to the main query. Moreover, a subquery can access columns from the from clause of the main query, as shown in my query where employee.empid is passed from the outer query to the inner query.

Edit:

When you use a subquery in a select clause, Oracle essentially treats it as a left join (you can see this in the explain plan for your query), with the cardinality of the rows being just one on the right for every row in the left.

Explanation for the left join

A left join is very handy, especially when you want to replace the select subquery due to its restrictions. There are no restrictions here on the number of rows of the tables in either side of the LEFT JOIN keyword.

For more information read Oracle Docs on subqueries and left join or left outer join.

>>> dic0 = {'dic0':0}
>>> dic1 = {'dic1':1}
>>> ndic = dict(dic0.items() + dic1.items())
>>> ndic
{'dic0': 0, 'dic1': 1}
>>>

I would stick with normal approach to call the file directly, but if you really want to call a function, have a look at JSON-RPC (JSON Remote Procedure Call).

You basically send a JSON string in a specific format to the server, e.g.

{ "method": "echo", "params": ["Hello JSON-RPC"], "id": 1}

which includes the function to call and the parameters of that function.

Of course the server has to know how to handle such requests.
Here is jQuery plugin for JSON-RPC and e.g. the Zend JSON Server as server implementation in PHP.

This might be overkill for a small project or less functions. Easiest way would be karim's answer. On the other hand, JSON-RPC is a standard.

What type() means:

I think your question is a bit more general than I originally thought. type() with one argument returns the type or class of the object. So if you have a = 'abc' and use type(a) this returns str because the variable a is a string. If b = 10, type(b) returns int.

See also python documentation on type().

For comparisons:

If you want a comparison you could use: if type(v) == h5py.h5r.Reference (to check if it is a h5py.h5r.Reference instance).

But it is recommended that one uses if isinstance(v, h5py.h5r.Reference) but then also subclasses will evaluate to True.

If you want to print the class use print v.__class__.__name__.

More generally: You can compare if two instances have the same class by using type(v) is type(other_v) or isinstance(v, other_v.__class__).

Is the javac executable in a directory that is part of your PATH?

I don't know the CentOS equivalent of the Windows path but if you cd to the java sdk directory and run ./javac does anything happen?

In case others have the same problem, I ran into this error after updating a project to 4.7. Oddly enough, I had to remove the System.ValueTuple reference for this error to go away.

What is Angular CLI Budgets? Budgets is one of the less known features of the Angular CLI. It’s a rather small but a very neat feature!

As applications grow in functionality, they also grow in size. Budgets is a feature in the Angular CLI which allows you to set budget thresholds in your configuration to ensure parts of your application stay within boundaries which you set — Official Documentation

Or in other words, we can describe our Angular application as a set of compiled JavaScript files called bundles which are produced by the build process. Angular budgets allows us to configure expected sizes of these bundles. More so, we can configure thresholds for conditions when we want to receive a warning or even fail build with an error if the bundle size gets too out of control!

How To Define A Budget? Angular budgets are defined in the angular.json file. Budgets are defined per project which makes sense because every app in a workspace has different needs.

Thinking pragmatically, it only makes sense to define budgets for the production builds. Prod build creates bundles with “true size” after applying all optimizations like tree-shaking and code minimization.

Oops, a build error! The maximum bundle size was exceeded. This is a great signal that tells us that something went wrong…

1. We might have experimented in our feature and didn’t clean up properly
2. Our tooling can go wrong and perform a bad auto-import, or we pick bad item from the suggested list of imports
3. We might import stuff from lazy modules in inappropriate locations
4. Our new feature is just really big and doesn’t fit into existing budgets

First Approach: Are your files gzipped?

Generally speaking, gzipped file has only about 20% the size of the original file, which can drastically decrease the initial load time of your app. To check if you have gzipped your files, just open the network tab of developer console. In the “Response Headers”, if you should see “Content-Encoding: gzip”, you are good to go.

How to gzip? If you host your Angular app in most of the cloud platforms or CDN, you should not worry about this issue as they probably have handled this for you. However, if you have your own server (such as NodeJS + expressJS) serving your Angular app, definitely check if the files are gzipped. The following is an example to gzip your static assets in a NodeJS + expressJS app. You can hardly imagine this dead simple middleware “compression” would reduce your bundle size from 2.21MB to 495.13KB.

const compression = require('compression')
const express = require('express')
const app = express()
app.use(compression())

Second Approach:: Analyze your Angular bundle

If your bundle size does get too big you may want to analyze your bundle because you may have used an inappropriate large-sized third party package or you forgot to remove some package if you are not using it anymore. Webpack has an amazing feature to give us a visual idea of the composition of a webpack bundle.

It’s super easy to get this graph.

1. npm install -g webpack-bundle-analyzer
2. In your Angular app, run ng build --stats-json (don’t use flag --prod). By enabling --stats-json you will get an additional file stats.json
3. Finally, run webpack-bundle-analyzer ./dist/stats.json and your browser will pop up the page at localhost:8888. Have fun with it.

I assume you are using Series.plot() to plot your data. If you look at the docs for Series.plot() here:

http://pandas.pydata.org/pandas-docs/dev/generated/pandas.Series.plot.html

there is no color parameter listed where you might be able to set the colors for your bar graph.

However, the Series.plot() docs state the following at the end of the parameter list:

kwds : keywords
Options to pass to matplotlib plotting method

What that means is that when you specify the kind argument for Series.plot() as bar, Series.plot() will actually call matplotlib.pyplot.bar(), and matplotlib.pyplot.bar() will be sent all the extra keyword arguments that you specify at the end of the argument list for Series.plot().

If you examine the docs for the matplotlib.pyplot.bar() method here:

http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.bar

..it also accepts keyword arguments at the end of it's parameter list, and if you peruse the list of recognized parameter names, one of them is color, which can be a sequence specifying the different colors for your bar graph.

Putting it all together, if you specify the color keyword argument at the end of your Series.plot() argument list, the keyword argument will be relayed to the matplotlib.pyplot.bar() method. Here is the proof:

import pandas as pd
import matplotlib.pyplot as plt

s = pd.Series(
    [5, 4, 4, 1, 12],
    index = ["AK", "AX", "GA", "SQ", "WN"]
)

#Set descriptions:
plt.title("Total Delay Incident Caused by Carrier")
plt.ylabel('Delay Incident')
plt.xlabel('Carrier')

#Set tick colors:
ax = plt.gca()
ax.tick_params(axis='x', colors='blue')
ax.tick_params(axis='y', colors='red')

#Plot the data:
my_colors = 'rgbkymc'  #red, green, blue, black, etc.

pd.Series.plot(
    s, 
    kind='bar', 
    color=my_colors,
)

plt.show()

Note that if there are more bars than colors in your sequence, the colors will repeat.

I would like to mention one case where you must use std::move() otherwise it will give an error. Case: If the return type of the function differs from the type of the local variable.

class Base { ... };
class Derived : public Base { ... };
...
std::unique_ptr<Base> Foo() {
     std::unique_ptr<Derived> derived(new Derived());
     return std::move(derived); //std::move() must
}

Probably the best way is via the built-in struct module:

>>> import struct
>>> x = 1245427
>>> struct.pack('>BH', x >> 16, x & 0xFFFF)
'\x13\x00\xf3'
>>> struct.pack('>L', x)[1:]  # could do it this way too
'\x13\x00\xf3'

Alternatively -- and I wouldn't usually recommend this, because it's mistake-prone -- you can do it "manually" by shifting and the chr() function:

>>> x = 1245427
>>> chr((x >> 16) & 0xFF) + chr((x >> 8) & 0xFF) + chr(x & 0xFF)
'\x13\x00\xf3'

Out of curiosity, why do you only want three bytes? Usually you'd pack such an integer into a full 32 bits (a C unsigned long), and use struct.pack('>L', 1245427) but skip the [1:] step?

I solved this with this commands:

1- Run the container

# docker run -d <image-name>

2- List containers

   # docker ps -a

3- Use the container ID

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

You can achieve that using DATE_FORMAT() (click the link for more other formats)

SELECT DATE_FORMAT(colName, '%Y-%m-%d') DATEONLY, 
       DATE_FORMAT(colName,'%H:%i:%s') TIMEONLY

SQLFiddle Demo

Works fine for me, please try:

.scroll-container {
  max-height: 250px;
  overflow: auto;
  -webkit-overflow-scrolling: touch;
}

Since C++11 you can make use of std::all_of and ::isdigit:

#include <algorithm>
#include <cctype>
#include <iostream>
#include <string_view>

int main([[maybe_unused]] int argc, [[maybe_unused]] char *argv[])
{
    auto isInt = [](std::string_view str) -> bool {
        return std::all_of(str.cbegin(), str.cend(), ::isdigit);
    };

    for(auto &test : {"abc", "123abc", "123.0", "+123", "-123", "123"}) {
        std::cout << "Is '" << test << "' numeric? " 
            << (isInt(test) ? "true" : "false") << std::endl;
    }

    return 0;
}

• SQL a language for talking to the database. It lets you select data, mutate and create database objects (like tables, views, etc.), change database settings.
• PL-SQL a procedural programming language (with embedded SQL)
• T-SQL (procedural) extensions for SQL used by SQL Server

If you're running PHP 5.3+ this will do the trick, place it at the topmost of your page:

if (get_magic_quotes_gpc() === 1)
{
    $_GET = json_decode(stripslashes(json_encode($_GET, JSON_HEX_APOS)), true);
    $_POST = json_decode(stripslashes(json_encode($_POST, JSON_HEX_APOS)), true);
    $_COOKIE = json_decode(stripslashes(json_encode($_COOKIE, JSON_HEX_APOS)), true);
    $_REQUEST = json_decode(stripslashes(json_encode($_REQUEST, JSON_HEX_APOS)), true);
}

Handles keys, values and multi-dimensional arrays.

you can specify which column to sort by, with following steps:

steps:
* top
* shift + F
* select a column from the list
    e.g. n means sort by memory,
* press enter
* ok

AndAlso is much like And, except it works like && in C#, C++, etc.

The difference is that if the first clause (the one before AndAlso) is true, the second clause is never evaluated - the compound logical expression is "short circuited".

This is sometimes very useful, e.g. in an expression such as:

If Not IsNull(myObj) AndAlso myObj.SomeProperty = 3 Then
   ...
End If

Using the old And in the above expression would throw a NullReferenceException if myObj were null.

In general it's best not to rely on finalize() to do any cleaning up etc.

According to the Javadoc (which it would be worth reading), it is:

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

As Joachim pointed out, this may never happen in the life of a program if the object is always accessible.

Also, the garbage collector is not guaranteed to run at any specific time. In general, what I'm trying to say is finalize() is probably not the best method to use in general unless there's something specific you need it for.

sub domain is part of the domain, it's like subletting a room of an apartment. A records has to be setup on the dns for the domain e.g

mydomain.com has IP 123.456.789.999 and hosted with Godaddy. Now to get the sub domain

anothersite.mydomain.com

of which the site is actually on another server then

login to Godaddy and add an A record ^dnsimple anothersite.mydomain.com and point the IP to the other server 98.22.11.11

And that's it.

Bootstrap-theme.css is the additional CSS file, which is optional for you to use. It gives 3D effects on the buttons and some other elements.

You need to ensure that auto-commit on the Connection is turned off, or setFetchSize will have no effect.

dbConnection.setAutoCommit(false);

Edit: Remembered that when I used this fix it was Postgres-specific, but hopefully it will still work for SQL Server.

You should not wrap JavaScript expressions in quotes.

<option data-img-src={this.props.imageUrl} value="1">{this.props.title}</option>

    printf("\n count =%d ascii=%s ",count,ascii);

 }

here is Iframe in view:

<iframe class="img-responsive" id="ifmReport" width="1090" height="1200" >

    </iframe>

Load it in script:

 $('#ifmReport').attr('src', '/ReportViewer/ReportViewer.aspx');

With Jquery... You can add class to html elements like this:

$(".divclass").find("p,h1,h2,h3,figure,span,a").addClass('nameclassorid');

nameclassorid no point or # at the beginning

A tricky bit is that TypeScript will 'double' map the enum in the emitted object, so it can be accessed both by key and value.

enum MyEnum {
    Part1 = 0,
    Part2 = 1
}

will be emitted as

{
   Part1: 0,
   Part2: 1,
   0: 'Part1',
   1: 'Part2'
}

So you should filter the object first before mapping. So @Diullei 's solution has the right answer. Here is my implementation:

// Helper
const StringIsNumber = value => isNaN(Number(value)) === false;

// Turn enum into array
function ToArray(enumme) {
    return Object.keys(enumme)
        .filter(StringIsNumber)
        .map(key => enumme[key]);
}

Use it like this:

export enum GoalProgressMeasurements {
    Percentage,
    Numeric_Target,
    Completed_Tasks,
    Average_Milestone_Progress,
    Not_Measured
}

console.log(ToArray(GoalProgressMeasurements));

"referencedColumnName" property is the name of the column in the table that you are making reference with the column you are anotating. Or in a short manner: it's the column referenced in the destination table. Imagine something like this: cars and persons. One person can have many cars but one car belongs only to one person (sorry, I don't like anyone else driving my car).

Table Person
name char(64) primary key
age int

Table Car
car_registration char(32) primary key
car_brand (char 64)
car_model (char64)
owner_name char(64) foreign key references Person(name)

When you implement classes you will have something like

class Person{
   ...
}

class Car{
    ...
    @ManyToOne
    @JoinColumn([column]name="owner_name", referencedColumnName="name")
    private Person owner;
}

EDIT: as @searchengine27 has commented, columnName does not exist as a field in persistence section of Java7 docs. I can't remember where I took this property from, but I remember using it, that's why I'm leaving it in my example.

Idiomatic Matlab plot(x1,y1,x2,y2) can be translated in R with ggplot2 for example in this way:

x1 <- seq(1,10,.2)
df1 <- data.frame(x=x1,y=log(x1),type="Log")
x2 <- seq(1,10)
df2 <- data.frame(x=x2,y=cumsum(1/x2),type="Harmonic")

df <- rbind(df1,df2)

library(ggplot2)
ggplot(df)+geom_line(aes(x,y,colour=type))

^{Inspired by Tingting Zhao's Dual line plots with different range of x-axis Using ggplot2.}

Combining approaches of @Denis and @Mark:

from collections import namedtuple
import inspect

class Node(namedtuple('Node', 'left right val')):
    __slots__ = ()
    def __new__(cls, *args, **kwargs):
        args_list = inspect.getargspec(super(Node, cls).__new__).args[len(args)+1:]
        params = {key: kwargs.get(key) for key in args_list + kwargs.keys()}
        return super(Node, cls).__new__(cls, *args, **params) 

That should support creating the tuple with positional arguments and also with mixed cases. Test cases:

>>> print Node()
Node(left=None, right=None, val=None)

>>> print Node(1,2,3)
Node(left=1, right=2, val=3)

>>> print Node(1, right=2)
Node(left=1, right=2, val=None)

>>> print Node(1, right=2, val=100)
Node(left=1, right=2, val=100)

>>> print Node(left=1, right=2, val=100)
Node(left=1, right=2, val=100)

>>> print Node(left=1, right=2)
Node(left=1, right=2, val=None)

but also support TypeError:

>>> Node(1, left=2)
TypeError: __new__() got multiple values for keyword argument 'left'

no need for the padding or the corners.

here's a sample:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
    <gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
        android:angle="270"/>
</shape>

Here are three different ways to do it:

Here's a working Demo in Fiddle Of All Three

Validation:

You can use native bootstrap validation states (No Custom CSS!):

<div class="form-group has-feedback">
    <label class="control-label" for="inputSuccess2">Name</label>
    <input type="text" class="form-control" id="inputSuccess2"/>
    <span class="glyphicon glyphicon-search form-control-feedback"></span>
</div>

For a full discussion, see my answer to Add a Bootstrap Glyphicon to Input Box

Input Group:

You can use the .input-group class like this:

<div class="input-group">
    <input type="text" class="form-control"/>
    <span class="input-group-addon">
        <i class="fa fa-search"></i>
    </span>
</div>

For a full discussion, see my answer to adding Twitter Bootstrap icon to Input box

Unstyled Input Group:

You can still use .input-group for positioning but just override the default styling to make the two elements appear separate.

Use a normal input group but add the class input-group-unstyled:

<div class="input-group input-group-unstyled">
    <input type="text" class="form-control" />
    <span class="input-group-addon">
        <i class="fa fa-search"></i>
    </span>
</div>

Then change the styling with the following css:

.input-group.input-group-unstyled input.form-control {
    -webkit-border-radius: 4px;
       -moz-border-radius: 4px;
            border-radius: 4px;
}
.input-group-unstyled .input-group-addon {
    border-radius: 4px;
    border: 0px;
    background-color: transparent;
}

Also, these solutions work for any input size

After= dependency is only effective when service including After= and service included by After= are both scheduled to start as part of your boot up.

Ex:

a.service
[Unit]
After=b.service

This way, if both a.service and b.service are enabled, then systemd will order b.service after a.service.

If I am not misunderstanding, what you are asking is how to start b.service when a.service starts even though b.service is not enabled.

The directive for this is Wants= or Requires= under [Unit].

website.service
[Unit]
Wants=mongodb.service
After=mongodb.service

The difference between Wants= and Requires= is that with Requires=, a failure to start b.service will cause the startup of a.service to fail, whereas with Wants=, a.service will start even if b.service fails. This is explained in detail on the man page of .unit.

If it is asking you for a username and password, your origin remote is pointing at the HTTPS URL rather than the SSH URL.

Change it to ssh.

For example, a GitHub project like Git will have an HTTPS URL:

https://github.com/<Username>/<Project>.git

And the SSH one:

[email protected]:<Username>/<Project>.git

You can do:

git remote set-url origin [email protected]:<Username>/<Project>.git

to change the URL.

create or replace procedure my_proc(  v_number IN number,p_rc OUT SYS_REFCURSOR )
as
begin
open p_rc
for select 1 col1
     from dual;
 end;
 /

and then write a function lie this which calls your stored procedure

 create or replace function my_proc_test(v_number IN NUMBER) RETURN sys_refcursor
 as
 p_rc sys_refcursor;
 begin
 my_proc(v_number,p_rc);
 return p_rc;
 end
 /

then you can run this SQL query in the SQLDeveloper editor.

 SELECT my_proc_test(3) FROM DUAL;

you will see the result in the console right click on it and cilck on single record view and edit the result you can see the all the records that were returned by the ref cursor.

Docker requires your command to keep running in the foreground. Otherwise, it thinks that your applications stops and shutdown the container.

So if your docker entry script is a background process like following:

/usr/local/bin/confd -interval=30 -backend etcd -node $CONFIG_CENTER &

The '&' makes the container stop and exit if there are no other foreground process triggered later. So the solution is just remove the '&' or have another foreground CMD running after it, such as

tail -f server.log

For anyone else who runs into this...

Version 1.2.0 of this plugin (current as of this post) doesn't quite work in all cases as documented with Bootstrap 3.0, but it does with a minor workaround.

Specifically, if using an input with icon, the HTML markup is of course slightly different as class names have changed:

<div class="input-group" data-datepicker="true">
    <input name="date" type="text" class="form-control" />
    <span class="input-group-addon"><i class="icon-calendar"></i></span>
</div>

It seems because of this, you need to use a selector that points directly to the input element itself NOT the parent container (which is what the auto generated HTML on the demo page suggests).

$('*[data-datepicker="true"] input[type="text"]').datepicker({
    todayBtn: true,
    orientation: "top left",
    autoclose: true,
    todayHighlight: true
});

Having done this you will probably also want to add a listener for clicking/tapping on the icon so it sets focus on the text input when clicked (which is the behaviour when using this plugin with TB 2.x by default).

$(document).on('touch click', '*[data-datepicker="true"] .input-group-addon', function(e){
    $('input[type="text"]', $(this).parent()).focus();
});

NB: I just use a data-datepicker boolean attribute because the class name 'datepicker' is reserved by the plugin and I already use 'date' for styling elements.

string s = "THIS IS MY TEXT RIGHT NOW";

s = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo.ToTitleCase(s.ToLower());

I had the same problem and I found out that if you add the URL param ?v=3 you won't get the warning message anymore:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3"></script>

Reproduction online

As pointed out in the comments by @Zia Ul Rehman Mughal

Turns out specifying this means you are referring to old frozen version 3.0 not the latest version. Frozen old versions are not updated with bug fixes or anything. But this is good to mention though. https://developers.google.com/maps/documentation/javascript/versions#the-frozen-version

Update 07-Jun-2016

This solution doesn't work anymore.

first of all check your internet its connect!

second is turn on WP_DEBUG and write this codes in wp-config.php

define('WP_DEBUG',true);
error_reporting('E_ALL');
ini_set('display_errors',1);

third is rename themes and plugins folder that in wp-content folder to other name sush as

pluginss , themess

S F my english!

You can do it like this:

row_id = 5;
row = $("body").find('#'+row_id);

AFAIK the delay method only works for numeric CSS modifications.

For other purposes JavaScript comes with a setTimeout method:

window.setTimeout(function(){$("#div").removeClass("error");}, 1000);

To do links, you can do

.social h2 a:link {
  color: pink;
  font-size: 14px;   
}

You can change the hover, visited, and active link styling too. Just replace "link" with what you want to style. You can learn more at the w3schools page CSS Links.

This is an important question. The SSL 3 protocol (1996) is irreparably broken by the Poodle attack published 2014. The IETF have published "SSLv3 MUST NOT be used". Web browsers are ditching it. Mozilla Firefox and Google Chrome have already done so.

Two excellent tools for checking protocol support in browsers are SSL Lab's client test and https://www.howsmyssl.com/ . The latter does not require Javascript, so you can try it from .NET's HttpClient:

// set proxy if you need to
// WebRequest.DefaultWebProxy = new WebProxy("http://localhost:3128");

File.WriteAllText("howsmyssl-httpclient.html", new HttpClient().GetStringAsync("https://www.howsmyssl.com").Result);

// alternative using WebClient for older framework versions
// new WebClient().DownloadFile("https://www.howsmyssl.com/", "howsmyssl-webclient.html");

The result is damning:

Your client is using TLS 1.0, which is very old, possibly susceptible to the BEAST attack, and doesn't have the best cipher suites available on it. Additions like AES-GCM, and SHA256 to replace MD5-SHA-1 are unavailable to a TLS 1.0 client as well as many more modern cipher suites.

That's concerning. It's comparable to 2006's Internet Explorer 7.

To list exactly which protocols a HTTP client supports, you can try the version-specific test servers below:

var test_servers = new Dictionary<string, string>();
test_servers["SSL 2"] = "https://www.ssllabs.com:10200";
test_servers["SSL 3"] = "https://www.ssllabs.com:10300";
test_servers["TLS 1.0"] = "https://www.ssllabs.com:10301";
test_servers["TLS 1.1"] = "https://www.ssllabs.com:10302";
test_servers["TLS 1.2"] = "https://www.ssllabs.com:10303";

var supported = new Func<string, bool>(url =>
{
    try { return new HttpClient().GetAsync(url).Result.IsSuccessStatusCode; }
    catch { return false; }
});

var supported_protocols = test_servers.Where(server => supported(server.Value));
Console.WriteLine(string.Join(", ", supported_protocols.Select(x => x.Key)));

I'm using .NET Framework 4.6.2. I found HttpClient supports only SSL 3 and TLS 1.0. That's concerning. This is comparable to 2006's Internet Explorer 7.

Update: It turns HttpClient does support TLS 1.1 and 1.2, but you have to turn them on manually at System.Net.ServicePointManager.SecurityProtocol. See https://stackoverflow.com/a/26392698/284795

I don't know why it uses bad protocols out-the-box. That seems a poor setup choice, tantamount to a major security bug (I bet plenty of applications don't change the default). How can we report it?

To be honest I just use:

select convert(nvarchar(max), GETDATE(), 112)

which gives YYYYMMDD and minus one from it.

Or more correctly

select convert(nvarchar(max), GETDATE(), 112) - 1 

for yesterdays date.

Replace Getdate() with your value OrderDate

select convert(nvarchar (max),OrderDate,112)-1 AS SubtractDate FROM Orders

should do it.

Solution 1: Copy any text

HTML

<button (click)="copyMessage('This goes to Clipboard')" value="click to copy" >Copy this</button>

.ts file

copyMessage(val: string){
    const selBox = document.createElement('textarea');
    selBox.style.position = 'fixed';
    selBox.style.left = '0';
    selBox.style.top = '0';
    selBox.style.opacity = '0';
    selBox.value = val;
    document.body.appendChild(selBox);
    selBox.focus();
    selBox.select();
    document.execCommand('copy');
    document.body.removeChild(selBox);
  }

Solution 2: Copy from a TextBox

HTML

 <input type="text" value="User input Text to copy" #userinput>
      <button (click)="copyInputMessage(userinput)" value="click to copy" >Copy from Textbox</button>

.ts file

    /* To copy Text from Textbox */
  copyInputMessage(inputElement){
    inputElement.select();
    document.execCommand('copy');
    inputElement.setSelectionRange(0, 0);
  }

Demo Here

Solution 3: Import a 3rd party directive ngx-clipboard

<button class="btn btn-default" type="button" ngxClipboard [cbContent]="Text to be copied">copy</button>

Solution 4: Custom Directive

If you prefer using a custom directive, Check Dan Dohotaru's answer which is an elegant solution implemented using ClipboardEvent.

Solution 5: Angular Material

Angular material 9 + users can utilize the built-in clipboard feature to copy text. There are a few more customization available such as limiting the number of attempts to copy data.

The problem, in my case, was that some install at some point defined an environment variable http_proxy on my machine when I had no proxy.

Removing the http_proxy environment variable fixed the problem.

You just need to:

Step 1: Go home directory of C:\ with typing cd.. (2 times)

Step 2: It appears now C:\>

Step 3: Type dir Windows\System32\run

That's all, it shows complete files & folder details inside target folder.

Details: I used Windows\System32\com folder as example, you should type your own folder name etc. Windows\System32\run

Oddly enough, the issue for me was I was trying to open 2012 SQL Server Integration Services on SSMS 2008 R2. When I opened the same in SSMS 2012, it connected right away.

As you would like to get argument (United) for which value is given (5) you might also consider using bidirectional map (e.g. provided by Guava: http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/collect/BiMap.html).

Here's a nifty utility I use:

/**
 * A common method for all enums since they can't have another base class
 * @param <T> Enum type
 * @param c enum type. All enums must be all caps.
 * @param string case insensitive
 * @return corresponding enum, or null
 */
public static <T extends Enum<T>> T getEnumFromString(Class<T> c, String string) {
    if( c != null && string != null ) {
        try {
            return Enum.valueOf(c, string.trim().toUpperCase());
        } catch(IllegalArgumentException ex) {
        }
    }
    return null;
}

Then in my enum class I usually have this to save some typing:

public static MyEnum fromString(String name) {
    return getEnumFromString(MyEnum.class, name);
}

If your enums are not all caps, just change the Enum.valueOf line.

Too bad I can't use T.class for Enum.valueOf as T is erased.

TLDR:

git pull is like running git fetch then git merge
git pull --rebase is like git fetch then git rebase

In reply to your first statement,

git pull is like a git fetch + git merge.

"In its default mode, git pull is shorthand for git fetch followed by git merge FETCH_HEAD" More precisely, git pull runs git fetch with the given parameters and then calls git merge to merge the retrieved branch heads into the current branch"

(Ref: https://git-scm.com/docs/git-pull)

For your second statement/question:

'But what is the difference between git pull VS git fetch + git rebase'

Again, from same source:
git pull --rebase

"With --rebase, it runs git rebase instead of git merge."

Now, if you wanted to ask

'the difference between merge and rebase'

that is answered here too:
https://git-scm.com/book/en/v2/Git-Branching-Rebasing
(the difference between altering the way version history is recorded)

Dim filepath as string
Sheets("Sheet 1").ChartObjects("Chart 1").Chart.Export filepath & "Name.jpg"

Slimmed down the code to the absolute minimum if needed.

one liner bash function validation

myFunction() {

    : ${1?"forgot to supply an argument"}
    if [ "$1" -gt "-1" ]; then
        echo hi
    fi

}

add function name and usage

myFunction() {

    : ${1?"forgot to supply an argument ${FUNCNAME[0]}() Usage:  ${FUNCNAME[0]} some_integer"}
    if [ "$1" -gt "-1" ]; then
        echo hi
    fi

}

add validation to check if integer

to add additional validation, for example to check to see if the argument passed is an integer, modify the validation one liner to call a validation function:

: ${1?"forgot to supply an argument ${FUNCNAME[0]}() Usage:  ${FUNCNAME[0]} some_integer"} && validateIntegers $1 || die "Must supply an integer!"

then, construct a validation function that validates the argument, returning 0 on success, 1 on failure and a die function that aborts script on failure

validateIntegers() {

    if ! [[ "$1" =~ ^[0-9]+$ ]]; then
        return 1 # failure
    fi
    return 0 #success

}

die() { echo "$*" 1>&2 ; exit 1; }

Even simpler - just use set -u

set -u makes sure that every referenced variable is set when its used, so just set it and forget it

myFunction() {
    set -u
    if [ "$1" -gt "-1" ]; then
        echo hi
    fi

}

Ok so I just found a really decent work around to this issue. CMDKEY works on windows 7+ and allows you to enter details into the windows cred manager from the cmd prompt, and if you use the /pass switch it provides its own password entry without exposing the password. It does not present ***** as you type but the password is hidden.

The script below requests the username as normal and creates a var called "%username%" it then checks to see if the cred manager already has an entry for the target server. If it does it just maps the drive to the usename and does not request a password. If there is no entry it then uses the CMDKEY to prompt for password and stores it in cred manager.

    set /p username="Enter School Username: "
    CMDKEY /list:SERVERNAME | FIND "NONE" > nul 2>&1
    IF %ERRORLEVEL% NEQ 0 GOTO MAPDRIVES
    CMDKEY /ADD:SERVERNAME /username:%username% /pass
    :MAPDRIVES
    NET USE Y: \\SERVERNAME\SHARE\%username%

I understand this post is old but if anybody is still searching and has not found a solution to the intellisense issue even after re-installing, applying the cumulative updates, or other methods, then I hope I may be of assistance.

I have Applied SQL 2008 R2 Service Pack 1 which you can download here
