Based on @ganaraj 's answer, and @dnc253 's answer, I just made a simple "directive" for the tree structure having selecting, adding, deleting, and editing feature.

Jsfiddle: http://jsfiddle.net/yoshiokatsuneo/9dzsms7y/

HTML:

<script type="text/ng-template" id="tree_item_renderer.html">
    <div class="node"  ng-class="{selected: data.selected}" ng-click="select(data)">
        <span ng-click="data.hide=!data.hide" style="display:inline-block; width:10px;">
            <span ng-show="data.hide && data.nodes.length > 0" class="fa fa-caret-right">+</span>
            <span ng-show="!data.hide && data.nodes.length > 0" class="fa fa-caret-down">-</span>
        </span>
        <span ng-show="!data.editting" ng-dblclick="edit($event)" >{{data.name}}</span>
        <span ng-show="data.editting"><input ng-model="data.name" ng-blur="unedit()" ng-focus="f()"></input></span>
        <button ng-click="add(data)">Add node</button>
        <button ng-click="delete(data)" ng-show="data.parent">Delete node</button>
    </div>
    <ul ng-show="!data.hide" style="list-style-type: none; padding-left: 15px">
        <li ng-repeat="data in data.nodes">
            <recursive><sub-tree data="data"></sub-tree></recursive>
        </li>
    </ul>
</script>
<ul ng-app="Application" style="list-style-type: none; padding-left: 0">
    <tree data='{name: "Node", nodes: [],show:true}'></tree>
</ul>

JavaScript:

angular.module("myApp",[]);

/* https://stackoverflow.com/a/14657310/1309218 */
angular.module("myApp").
directive("recursive", function($compile) {
    return {

        template: '<sub-tree data="data" root="data"></sub-tree>',
        controller: function($scope){
            this.select = function(data){
                if($scope.selected){
                    $scope.selected.selected = false;
                }
                data.selected = true;
                $scope.selected = data;
            };
        },
        scope: {
            data: '=',
        }
    }
});

I've been playing around with syntax to do this sort of thing, but it requires some helpers that are a little unusual. It starts with not using 'var' at all, but a simple 'DECLARE' helper that creates a local variable and defines a scope for it via an anonymous callback. By controlling how variables are declared, we can choose to wrap them into objects so that they can always be passed by reference, essentially. This is similar to one of the Eduardo Cuomo's answer above, but the solution below does not require using strings as variable identifiers. Here's some minimal code to show the concept.

function Wrapper(val){
    this.VAL = val;
}
Wrapper.prototype.toString = function(){
    return this.VAL.toString();
}

function DECLARE(val, callback){
    var valWrapped = new Wrapper(val);    
    callback(valWrapped);
}

function INC(ref){
    if(ref && ref.hasOwnProperty('VAL')){
        ref.VAL++; 
    }
    else{
        ref++;//or maybe throw here instead?
    }

    return ref;
}

DECLARE(5, function(five){ //consider this line the same as 'let five = 5'
console.log("five is now " + five);
INC(five); // increment
console.log("five is incremented to " + five);
});

cp -Rvn /source/path/* /destination/path/
cp: /destination/path/any.zip: No such file or directory

It will create no existing paths in destination, if path have a source file inside. This dont create empty directories.

A moment ago i've seen xxxxxxxx: No such file or directory, because i run out of free space. without error message.

with ditto:

ditto -V /source/path/* /destination/path
ditto: /destination/path/any.zip: No space left on device

once freed space cp -Rvn /source/path/* /destination/path/ works as expected

Depending on your PHP configuration, this may be a easy as using:

$jsonData = json_decode(file_get_contents('https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello|World&chof=json'));

However, if allow_url_fopen isn't enabled on your system, you could read the data via CURL as follows:

<?php
    $curlSession = curl_init();
    curl_setopt($curlSession, CURLOPT_URL, 'https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello|World&chof=json');
    curl_setopt($curlSession, CURLOPT_BINARYTRANSFER, true);
    curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, true);

    $jsonData = json_decode(curl_exec($curlSession));
    curl_close($curlSession);
?>

Incidentally, if you just want the raw JSON data, then simply remove the json_decode.

Take a look at the getopt library; it's pretty much the gold standard for this sort of thing.

As a good example may be worth it to navigate to this project and see how to handle exiting processes grammatically or in this snippet from VM found in here

                ConsoleOutputStream = new ObservableCollection<string>();

                var startInfo = new ProcessStartInfo(FilePath)
                {
                    WorkingDirectory = RootFolderPath,
                    Arguments = StartingArguments,
                    RedirectStandardOutput = true,
                    UseShellExecute = false,
                    CreateNoWindow = true
                };
                ConsoleProcess = new Process {StartInfo = startInfo};

                ConsoleProcess.EnableRaisingEvents = true;

                ConsoleProcess.OutputDataReceived += (sender, args) =>
                {
                    App.Current.Dispatcher.Invoke((System.Action) delegate
                    {
                        ConsoleOutputStream.Insert(0, args.Data);
                        //ConsoleOutputStream.Add(args.Data);
                    });
                };
                ConsoleProcess.Exited += (sender, args) =>
                {
                    InProgress = false;
                };

                ConsoleProcess.Start();
                ConsoleProcess.BeginOutputReadLine();
        }
    }

    private void RegisterProcessWatcher()
    {
        startWatch = new ManagementEventWatcher(
            new WqlEventQuery($"SELECT * FROM Win32_ProcessStartTrace where ProcessName = '{FileName}'"));
        startWatch.EventArrived += new EventArrivedEventHandler(startProcessWatch_EventArrived);

        stopWatch = new ManagementEventWatcher(
            new WqlEventQuery($"SELECT * FROM Win32_ProcessStopTrace where ProcessName = '{FileName}'"));
        stopWatch.EventArrived += new EventArrivedEventHandler(stopProcessWatch_EventArrived);
    }

    private void stopProcessWatch_EventArrived(object sender, EventArrivedEventArgs e)
    {
        InProgress = false;
    }

    private void startProcessWatch_EventArrived(object sender, EventArrivedEventArgs e)
    {
        InProgress = true;
    }

I found one way to access the shared folder without giving the username and password.

We need to change the share folder protect settings in the machine where the folder has been shared.

Go to Control Panel > Network and sharing center > Change advanced sharing settings > Enable Turn Off password protect sharing option.

By doing the above settings we can access the shared folder without any username/password.

As previously mentioned, the bundler version may be too high for your version of rails.

I ran into the same problem using Rails 3.0.1 which requires Bundler v1.0.0 - v1.0.22

Check your bundler version using: gem list bundler

If your bundler version is not within the appropriate range, I found this solution to work: rvm @global do gem uninstall bundler

Note: rvm is required for this solution... another case for why you should be using rvm in the first place.

Centering the child elements in a div. It works for all screen sizes

#parent {
    padding: 5% 0;
}

#child {
    padding: 10% 0;
}

<div id="parent">
    <div id="child">Content here</div>
</div>

for more details, you can visit to this link

use the following commands instead:

ALTER TABLE table_name DISABLE TRIGGER tr_name

ALTER TABLE table_name ENABLE TRIGGER tr_name

One other trick is to use ind2sub and sub2ind. In conjunction with numel and size, this can let you do stuff like the following, which creates an N-dimensional array, and then sets all the elements on the "diagonal" to be 1.

d = zeros( 3, 4, 5, 6 ); % Let's pretend this is a user input
nel = numel( d );
sz = size( d );
szargs = cell( 1, ndims( d ) ); % We'll use this with ind2sub in the loop
for ii=1:nel
    [ szargs{:} ] = ind2sub( sz, ii ); % Convert linear index back to subscripts
    if all( [szargs{2:end}] == szargs{1} ) % On the diagonal?
        d( ii ) = 1;
    end
end

The root problem here seems that iOS8 safari won't hide the address bar when scrolling down if the content is equal or less than the viewport.

As you found out already, adding some padding at the bottom gets around this issue:

html {
    /* enough space to scroll up to get fullscreen on iOS8 */
    padding-bottom: 80px;
}

// sort of emulate safari's "bounce back to top" scroll
window.addEventListener('scroll', function(ev) {
    // avoids scrolling when the focused element is e.g. an input
    if (
        !document.activeElement
        || document.activeElement === document.body
    ) {
        document.body.scrollIntoViewIfNeeded(true);
    }
});

The above css should be conditionally applied, for example with UA sniffing adding a gt-ios8 class to <html>.

: has special meaning: it is The time separator. (Custom Date and Time Format Strings).

Use \ to escape it:

DateTime.ToString(@"MM/dd/yyyy HH\:mm\:ss.fff")

Or use CultureInfo.InvariantCulture:

DateTime.ToString("MM/dd/yyyy HH:mm:ss.fff", CultureInfo.InvariantCulture)

I would suggest going with the second one, because / has special meaning as well (it is The date separator.), so you can have problems with that too.

I really respect all the above answers. From my opinion Yes! For sure it is worth to use re.compile instead of compiling the regex, again and again, every time.

Using re.compile makes your code more dynamic, as you can call the already compiled regex, instead of compiling again and aagain. This thing benefits you in cases:

1. Processor Efforts
2. Time Complexity.
3. Makes regex Universal.(can be used in findall, search, match)
4. And makes your program looks cool.

Example :

  example_string = "The room number of her room is 26A7B."
  find_alpha_numeric_string = re.compile(r"\b\w+\b")

Using in Findall

 find_alpha_numeric_string.findall(example_string)

Using in search

  find_alpha_numeric_string.search(example_string)

Similarly you can use it for: Match and Substitute

<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<script>

function showButtons () { $('#b1, #b2, #b3').show(); }

</script>
<style type="text/css">
#b1, #b2, #b3 {
display: none;
}

</style>
</head>
<body>

<a href="#" onclick="showButtons();">Show me the money!</a>

<input type="submit" id="b1" value="B1" />
<input type="submit" id="b2" value="B2"/>
<input type="submit" id="b3" value="B3" />

</body>
</html>

You can define a boolean and change it to false when you want to stop handler. Like this..

boolean stop = false;

handler.postDelayed(new Runnable() {
    @Override
    public void run() {

        //do your work here..

        if (!stop) {
            handler.postDelayed(this, delay);
        }
    }
}, delay);

These files are from Maven wrapper. It works similarly to the Gradle wrapper.

This allows you to run the Maven project without having Maven installed and present on the path. It downloads the correct Maven version if it's not found (as far as I know by default in your user home directory).

The mvnw file is for Linux (bash) and the mvnw.cmd is for the Windows environment.

To create or update all necessary Maven Wrapper files execute the following command:

mvn -N io.takari:maven:wrapper

To use a different version of maven you can specify the version as follows:

mvn -N io.takari:maven:wrapper -Dmaven=3.3.3

Both commands require maven on PATH (add the path to maven bin to Path on System Variables) if you already have mvnw in your project you can use ./mvnw instead of mvn in the commands.

"Upstream" would refer to the main repo that other people will be pulling from, e.g. your GitHub repo. The -u option automatically sets that upstream for you, linking your repo to a central one. That way, in the future, Git "knows" where you want to push to and where you want to pull from, so you can use git pull or git push without arguments. A little bit down, this article explains and demonstrates this concept.

Global variables are not extern nor static by default on C and C++. When you declare a variable as static, you are restricting it to the current source file. If you declare it as extern, you are saying that the variable exists, but are defined somewhere else, and if you don't have it defined elsewhere (without the extern keyword) you will get a link error (symbol not found).

Your code will break when you have more source files including that header, on link time you will have multiple references to varGlobal. If you declare it as static, then it will work with multiple sources (I mean, it will compile and link), but each source will have its own varGlobal.

What you can do in C++, that you can't in C, is to declare the variable as const on the header, like this:

const int varGlobal = 7;

And include in multiple sources, without breaking things at link time. The idea is to replace the old C style #define for constants.

If you need a global variable visible on multiple sources and not const, declare it as extern on the header, and then define it, this time without the extern keyword, on a source file:

Header included by multiple files:

extern int varGlobal;

In one of your source files:

int varGlobal = 7;

The size is four bytes because the enum is stored as an int. With only 12 values, you really only need 4 bits, but 32 bit machines process 32 bit quantities more efficiently than smaller quantities.

0 0 0 0  January
0 0 0 1  February
0 0 1 0  March
0 0 1 1  April
0 1 0 0  May
0 1 0 1  June
0 1 1 0  July
0 1 1 1  August
1 0 0 0  September
1 0 0 1  October
1 0 1 0  November
1 0 1 1  December
1 1 0 0  ** unused **
1 1 0 1  ** unused **
1 1 1 0  ** unused **
1 1 1 1  ** unused **

Without enums, you might be tempted to use raw integers to represent the months. That would work and be efficient, but it would make your code hard to read. With enums, you get efficient storage and readability.

Color definitions with transparency information may be in the form

#AARRGGBB or #ARGB.

You can use also the shorter value for full transparency: #0000.

Other values are e.g.:

white  grey   black
#FFFF  #F888  #F000 - full color
#EFFF  #E888  #E000
#DFFF  #D888  #D000
#CFFF  #C888  #C000
#BFFF  #B888  #B000
#AFFF  #A888  #A000
#9FFF  #9888  #9000
#8FFF  #8888  #8000
#7FFF  #7888  #7000
#6FFF  #6888  #6000
#5FFF  #5888  #5000
#4FFF  #4888  #4000
#3FFF  #3888  #3000
#2FFF  #2888  #2000
#1FFF  #1888  #1000
#0FFF  #0888  #0000 - full transparency

Ok, I'll take a stab at this. If you want to work with PHP, you will need to install and configure both PHP and a webserver on your machine. This article might get you started: PHP Manual: Installation on Windows systems

Once you have your environment setup, you can start working with webforms. Directly From the article: Processing form data with PHP:

For this example you will need to create two pages. On the first page we will create a simple HTML form to collect some data. Here is an example:

<html>   
<head>
 <title>Test Page</title>
</head>   
<body>   
    <h2>Data Collection</h2><p>
    <form action="process.php" method="post">  
        <table>
            <tr>
                <td>Name:</td>
                <td><input type="text" name="Name"/></td>
            </tr>   
            <tr>
                <td>Age:</td>
                <td><input type="text" name="Age"/></td>
            </tr>   
            <tr>
                <td colspan="2" align="center">
                <input type="submit"/>
                </td>
            </tr>
        </table>
    </form>
</body>
</html>

This page will send the Name and Age data to the page process.php. Now lets create process.php to use the data from the HTML form we made:

<?php   
    print "Your name is ". $Name;   
    print "<br />";   
    print "You are ". $Age . " years old";   
    print "<br />";   $old = 25 + $Age;
    print "In 25 years you will be " . $old . " years old";   
?>

As you may be aware, if you leave out the method="post" part of the form, the URL with show the data. For example if your name is Bill Jones and you are 35 years old, our process.php page will display as http://yoursite.com/process.php?Name=Bill+Jones&Age=35 If you want, you can manually change the URL in this way and the output will change accordingly.

Additional JavaScript Example

This single file example takes the html from your question and ties the onSubmit event of the form to a JavaScript function that pulls the values of the 2 textboxes and displays them in an alert box.

Note: document.getElementById("fname").value gets the object with the ID tag that equals fname and then pulls it's value - which in this case is the text in the First Name textbox.

 <html>
    <head>
     <script type="text/javascript">
     function ExampleJS(){
        var jFirst = document.getElementById("fname").value;
        var jLast = document.getElementById("lname").value;
        alert("Your name is: " + jFirst + " " + jLast);
     }
     </script>

    </head>
    <body>
        <FORM NAME="myform" onSubmit="JavaScript:ExampleJS()">

             First name: <input type="text" id="fname" name="firstname" /><br />
             Last name:  <input type="text" id="lname" name="lastname" /><br />
            <input name="Submit"  type="submit" value="Update" />
        </FORM>
    </body>
</html>

Here you go:

DECLARE
BEGIN
  dbms_output.enable(NULL); -- Disables the limit of DBMS
  -- Your print here !
END;

you can try this too. I use just framelayout.

 <FrameLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@drawable/cover"
                android:gravity="bottom">

                <TextView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:textAppearance="?android:attr/textAppearanceMedium"
                    android:text="Hello !"
                    android:id="@+id/welcomeTV"
                    android:textColor="@color/textColor"
                    android:layout_gravity="left|bottom" />
            </FrameLayout>

You can use lambda expressions

private void MyMethod(string param1,int param2)
{
  //do stuff
}
Thread myNewThread = new Thread(() => MyMethod("param1",5));
myNewThread.Start();

this is so far the best answer i could find, it's fast and easy.

function numberPadding(n, p) {
  n = n.toString();
  var len = p - n.length;
  if (len > 0) {
    for (var i=0; i < len; i++) {
      n = '0' + n;
    }
  }
  return n;
}

For anyone that wants to watch for a change to an object within an array of objects, this seemed to work for me (as the other solutions on this page didn't):

function MyController($scope) {

    $scope.array = [
        data1: {
            name: 'name',
            surname: 'surname'
        },
        data2: {
            name: 'name',
            surname: 'surname'
        },
    ]


    $scope.$watch(function() {
        return $scope.data,
    function(newVal, oldVal){
        console.log(newVal, oldVal);
    }, true);

I solved this problem using the split npm module. Pipe your stream into split, and it will "Break up a stream and reassemble it so that each line is a chunk".

Sample code:

var fs = require('fs')
  , split = require('split')
  ;

var stream = fs.createReadStream(filePath, {flags: 'r', encoding: 'utf-8'});
var lineStream = stream.pipe(split());
linestream.on('data', function(chunk) {
    var json = JSON.parse(chunk);           
    // ...
});

process.stdin.pipe(process.stdout);

Just add the classes to your html

<div class="someDiv radius opacity"></div>

Works for positive or negative numbers

int start = -3;
int end = 6;

for (int val = start; val < end; val++)
{
    // Condition to Check Even, Not condition (!) will give Odd number
    if (val % 2 == 0) 
    {
        System.out.println("Even" + val);
    }
    else
    {
        System.out.println("Odd" + val);
    }
}

If you look at the down arrow in environment tab. The attached file can appear multiple times. You may need to highlight and run detach(filename) several times until all cases are gone then attach(newfilename) should have no output message.

I took another try at it, using the DataContractJsonSerializer class. This solves it:

The code looks like this:

using System.Runtime.Serialization;

[DataContract]
public class DataObject
{
    [DataMember(Name = "user_id")]
    public int UserId { get; set; }

    [DataMember(Name = "detail_level")]
    public string DetailLevel { get; set; }
}

And the test is:

using System.Runtime.Serialization.Json;

[TestMethod]
public void DataObjectSimpleParseTest()
{
        DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(DataObject));

        MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(JsonData));
        DataObject dataObject = serializer.ReadObject(ms) as DataObject;

        Assert.IsNotNull(dataObject);
        Assert.AreEqual("low", dataObject.DetailLevel);
        Assert.AreEqual(1234, dataObject.UserId);
}

The only drawback is that I had to change DetailLevel from an enum to a string - if you keep the enum type in place, the DataContractJsonSerializer expects to read a numeric value and fails. See DataContractJsonSerializer and Enums for further details.

In my opinion this is quite poor, especially as JavaScriptSerializer handles it correctly. This is the exception that you get trying to parse a string into an enum:

System.Runtime.Serialization.SerializationException: There was an error deserializing the object of type DataObject. The value 'low' cannot be parsed as the type 'Int64'. --->
System.Xml.XmlException: The value 'low' cannot be parsed as the type 'Int64'. --->  
System.FormatException: Input string was not in a correct format

And marking up the enum like this does not change this behaviour:

[DataContract]
public enum DetailLevel
{
    [EnumMember(Value = "low")]
    Low,
   ...
 }

This also seems to work in Silverlight.

From the keytool man - it imports certificate chain, if input is given in PKCS#7 format, otherwise only the single certificate is imported. You should be able to convert certificates to PKCS#7 format with openssl, via openssl crl2pkcs7 command.

Android Looper is a wrapper to attach MessageQueue to Thread and it manages Queue processing. It looks very cryptic in Android documentation and many times we may face Looper related UI access issues. If we don't understand the basics it becomes very tough to handle.

Here is an article which explains Looper life cycle, how to use it and usage of Looper in Handler

Looper = Thread + MessageQueue

Try this:

$(document).ready( function () {
  $('#example').dataTable({
    "order": []
  });
});

this will solve your problem.

I actually prefer the following in SQL Server 2008:

SELECT Table1.Column1, Table1.Column2, Table2.Column1, Table2.Column2, 'Some String' AS SomeString, 8 AS SomeInt
INTO Table3
FROM Table1 INNER JOIN Table2 ON Table1.Column1 = Table2.Column3

It eliminates the step of adding the Insert () set, and you just select which values go in the table.

This can't be done by using a Comparator, as it will always get the key of the map to compare. TreeMap can only sort by the key.

private void datagrid_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
    string test = this.datagrid.Columns[e.ColumnIndex].HeaderText;
}

This code will get the HeaderText value.

import datetime
now = datetime.datetime.now()
print now.strftime("%b %_d")

Two other ways are strcpy(str, ""); and string[0] = 0

To really delete the Variable contents (in case you have dirty code which is not working properly with the snippets above :P ) use a loop like in the example below.

#include <string.h>

...

int i=0;
for(i=0;i<strlen(string);i++)
{
    string[i] = 0;
}

In case you want to clear a dynamic allocated array of chars from the beginning, you may either use a combination of malloc() and memset() or - and this is way faster - calloc() which does the same thing as malloc but initializing the whole array with Null.

At last i want you to have your runtime in mind. All the way more, if you're handling huge arrays (6 digits and above) you should try to set the first value to Null instead of running memset() through the whole String.

It may look dirtier at first, but is way faster. You just need to pay more attention on your code ;)

I hope this was useful for anybody ;)

Java (at least 5 and 6, java 7 Paths solved most) has a problem with UNC and URI. Eclipse team wrapped it up here : http://wiki.eclipse.org/Eclipse/UNC_Paths

From java.io.File javadocs, the UNC prefix is "////", and java.net.URI handles file:////host/path (four slashes).

More details on why this happens and possible problems it causes in other URI and URL methods can be found in the list of bugs at the end of the link given above.

Using these informations, Eclipse team developed org.eclipse.core.runtime.URIUtil class, which source code can probably help out when dealing with UNC paths.

If you what to add bootstrap attributes in anchor tag dynamically than this will helps you lot

 $(".dropdown a").attr({
      class: "dropdown-toggle",
     'data-toggle': "dropdown",
      role: "button",
     'aria-haspopup': "true",
     'aria-expanded': "true"
});

What worked for me is:

GoTo

setting.gradle

1. change the name in it.
2. go to the app root folder which you want to change and refactor--> rename it.
3. close the android studio.
4. browse to the folder and change the name
5. start android studio again.
6. do the gradle sync.

And you are done!

I know the question is about setting a input but just in case if you want to set a combobox then (I search net for it and didn't find anything and this place seems a right place to guide others)

If you had a form with ID attribute set (e.g. frm1) and you wanted to set a specific specific combobox, with no ID set but name attribute set (e.g. district); then use

$("#frm1 select[name='district'] option[value='NWFP']").attr('selected', true);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>_x000D_
    <form id="frm1">_x000D_
        <select name="district">_x000D_
            <option value="" disabled="" selected="" hidden="">Area ...</option>_x000D_
            <option value="NWFP">NWFP</option>_x000D_
            <option value="FATA">FATA</option>_x000D_
        </select>_x000D_
    </form>

Although cursors usually considered horrible evil I believe this is a case for FAST_FORWARD cursor - the closest thing you can get to FOREACH in TSQL.

Delete the .android folder from your Documents&settings\User\ on XP and \User\ on Win7. Recreate the AVD again and create a new project.

While @coolscitist's answer worked for me, there is also a way that does not clutter your kernel environment with the complete jupyter package+deps. It is described in the ipython docs and is (I suspect) only necessary if you run the notebook server in a non-base environment.

conda activate name_of_your_kernel_env
conda install ipykernel
python -m ipykernel install --prefix=/home/your_username/.conda/envs/name_of_your_jupyter_server_env --name 'name_of_your_kernel_env'

You can check if it works using

conda activate name_of_your_jupyter_server_env 
jupyter kernelspec list

In my case I just need to import my newly created component to RouterModule

{path: 'newPath', component: newComponent}

Then in your app.module import the router and configure the routes:

import { RouterModule } from '@angular/router';

imports: [
        RouterModule.forRoot([
            {path: '', component: DashboardComponent},
            {path: 'dashboard', component: DashboardComponent},
            {path: 'newPath', component: newComponent}
        ])
    ],

Hope this helps to some one !!!

For Current date and time as the name for a file on the file system. Now call the string.Format method, and combine it with DateTime.Now, for a method that outputs the correct string based on the date and time.

using System;
using System.IO;

class Program
{
    static void Main()
    {
        //
        // Write file containing the date with BIN extension
        //
        string n = string.Format("text-{0:yyyy-MM-dd_hh-mm-ss-tt}.bin",
            DateTime.Now);
        File.WriteAllText(n, "abc");
    }
}

Output :

C:\Users\Fez\Documents\text-2020-01-08_05-23-13-PM.bin

"text-{0:yyyy-MM-dd_hh-mm-ss-tt}.bin"

text- The first part of the output required Files will all start with text-

{0: Indicates that this is a string placeholder The zero indicates the index of the parameters inserted here

yyyy- Prints the year in four digits followed by a dash This has a "year 10000" problem

MM- Prints the month in two digits

dd_ Prints the day in two digits followed by an underscore

hh- Prints the hour in two digits

mm- Prints the minute, also in two digits

ss- As expected, it prints the seconds

tt Prints AM or PM depending on the time of day

If you happen to work in a Unix environment, the expand command is what you need:

You can use nonHistorySelectors option from jquery mobile where you do not want to track history. You can find the detailed documentation here http://jquerymobile.com/demos/1.0a4.1/#docs/api/globalconfig.html

In your controller, render the new action from your create action if validation fails, with an instance variable, @car populated from the user input (i.e., the params hash). Then, in your view, add a logic check (either an if block around the form or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car is set.

Bottom line: ! methods just change the value of the object they are called upon, whereas a method without ! returns a manipulated value without writing over the object the method was called upon.

Only use ! if you do not plan on needing the original value stored at the variable you called the method on.

I prefer to do something like:

foo = "word"
bar = foo.capitalize
puts bar

OR

foo = "word"
puts foo.capitalize

Instead of

foo = "word"
foo.capitalize!
puts foo

Just in case I would like to access the original value again.

For pasting something that is the system clipboard you can just use SHIFT - INS.

It works in Windows, but I am guessing it works well in Linux too.

  audio.play();_x000D_

Thanks to the other answers here and after some experimentation I've created some very useful extension methods:

public static string GetRelativePathFrom(this FileSystemInfo to, FileSystemInfo from)
{
    return from.GetRelativePathTo(to);
}

public static string GetRelativePathTo(this FileSystemInfo from, FileSystemInfo to)
{
    Func<FileSystemInfo, string> getPath = fsi =>
    {
        var d = fsi as DirectoryInfo;
        return d == null ? fsi.FullName : d.FullName.TrimEnd('\\') + "\\";
    };

    var fromPath = getPath(from);
    var toPath = getPath(to);

    var fromUri = new Uri(fromPath);
    var toUri = new Uri(toPath);

    var relativeUri = fromUri.MakeRelativeUri(toUri);
    var relativePath = Uri.UnescapeDataString(relativeUri.ToString());

    return relativePath.Replace('/', Path.DirectorySeparatorChar);
}

Important points:

• Use FileInfo and DirectoryInfo as method parameters so there is no ambiguity as to what is being worked with. Uri.MakeRelativeUri expects directories to end with a trailing slash.
• DirectoryInfo.FullName doesn't normalize the trailing slash. It outputs whatever path was used in the constructor. This extension method takes care of that for you.

I recently posted a free software library for this: "html5csv.js" -- GitHub

It is intended to help streamline the creation of small simulator apps in Javascript that might need to import or export csv files, manipulate, display, edit the data, perform various mathematical procedures like fitting, etc.

After loading "html5csv.js" the problem of scanning a table and creating a CSV is a one-liner:

CSV.begin('#PrintDiv').download('MyData.csv').go();

Here is a JSFiddle demo of your example with this code.

Internally, for Firefox/Chrome this is a data URL oriented solution, similar to that proposed by @italo, @lepe, and @adeneo (on another question). For IE

The CSV.begin() call sets up the system to read the data into an internal array. That fetch then occurs. Then the .download() generates a data URL link internally and clicks it with a link-clicker. This pushes a file to the end user.

According to caniuse IE10 doesn't support <a download=...>. So for IE my library calls navigator.msSaveBlob() internally, as suggested by @Manu Sharma

Here is a complete sample to show RecyclerView with 2 types, the view type decide by the object

What worked for me is this solution to another question. Closing Xcode and reopening the project as workspace.
Go to your project folder and open .xcodeworkspace file.
Once you open the workspace (instead of project), Pods should appear as top level project in Project Navigator.

Not sure if you still need this, but in http://www.appbrain.com/ , you look up the app and the package name is in the url. For example: http://www.appbrain.com/app/fruit-ninja/com.halfbrick.fruitninja is the link for fruit ninja. Notice the bold

You can use Model.update() method.

With async/await:

try{
  const result = await Project.update(
    { title: "Updated Title" }, //what going to be updated
    { where: { id: 1 }} // where clause
  )  
} catch (error) {
  // error handling
}

With .then().catch():

Project.update(
    { title: "Updated Title" }, //what going to be updated
    { where: { id: 1 }} // where clause
)
.then(result => {
  // code with result
})
.catch(error => {
  // error handling
})

I really like the solution proposed by @Brian Diggs. However, in my case, I create the line plots in a loop rather than giving them explicitly because I do not know apriori how many plots I will have. When I tried to adapt the @Brian's code I faced some problems with handling the colors correctly. Turned out I needed to modify the aesthetic functions. In case someone has the same problem, here is the code that worked for me.

I used the same data frame as @Brian:

data <- structure(list(month = structure(c(1317452400, 1317538800, 1317625200, 1317711600,

                                       1318143600, 1318230000, 1318316400, 1318402800,

In my case, I generate my.cols and my.names dynamically, but I don't want to make things unnecessarily complicated so I give them explicitly here. These three lines make the ordering of the legend and assigning colors easier.

my.cols <- heat.colors(3, alpha=1)
my.names <- c("TempMin", "TempMed", "TempMax")
names(my.cols) <- my.names

And here is the plot:

p <-  ggplot(data, aes(x = month))

for (i in 1:3){
  p <- p + geom_line(aes_(y = as.name(names(data[i+1])), colour = 
colnames(data[i+1])))#as.character(my.names[i])))
}
p + scale_colour_manual("", 
                        breaks = as.character(my.names),
                        values = my.cols)
p

Just an add on for SQLite you can also use

CURRENT_TIME
CURRENT_DATE
CURRENT_TIMESTAMP

for the current time, current date and current timestamp. You will get the same results as for SQL

sql sqlite

You can use the git merge-base command to find the latest common commit between the two branches. If that commit is the same as your branch head, then the branch has been completely merged.

Note that git branch -d does this sort of thing already because it will refuse to delete a branch that hasn't already been completely merged.

"client": [

  "client_info": {

    "android_client_info": {
      "package_name": "[packagename]"
    }
  }

package_name must match what's in your manifest file. you can find the google-services.json file if you look in the example photo below.

Many of us get this error after setting up the eclipse and server for first time. This solution is -

1. go to server tab

2. select the properties option of your respective server and expand it

3. in the properties window , select general tab -> click Switch Location -> click apply ->click ok.

This may work .

There are a bunch of reasons here: http://macresearch.org/difference-between-alloc-init-and-new

Some selected ones are:

• new doesn't support custom initializers (like initWithString)
• alloc-init is more explicit than new

General opinion seems to be that you should use whatever you're comfortable with.

I used the node net module to open a socket to the webservice.

/* on Login request */
socket.on('login', function(credentials /* {username} {password} */){   
    if( !_this.netConnected ){
        _this.net.connect(8081, '127.0.0.1', function() {
            logger.gps('('+socket.id + ') '+credentials.username+' connected to: 127.0.0.1:8081');
            _this.netConnected = true;
            _this.username = credentials.username;
            _this.password = credentials.password;
            _this.m_RequestId = 1;
            /* make SOAP Login request */
            soapGps('', _this, 'login', credentials.username);              
        });         
    } else {
        /* make SOAP Login request */
        _this.m_RequestId = _this.m_RequestId +1;
        soapGps('', _this, 'login', credentials.username);          
    }
});

Send soap requests

/* SOAP request func */
module.exports = function soapGps(xmlResponse, client, header, data) {
    /* send Login request */
    if(header == 'login'){
        var SOAP_Headers =  "POST /soap/gps/login HTTP/1.1\r\nHost: soap.example.com\r\nUser-Agent: SOAP-client/SecurityCenter3.0\r\n" +
                            "Content-Type: application/soap+xml; charset=\"utf-8\"";        
        var SOAP_Envelope=  "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" +

        client.net.write(SOAP_Headers + "\r\nContent-Length:" + SOAP_Envelope.length.toString() + "\r\n\r\n");
        client.net.write(SOAP_Envelope);
        return;
    }

Parse soap response, i used module - xml2js

var parser = new xml2js.Parser({
    normalize: true,
    trim: true,
    explicitArray: false
});
//client.net.setEncoding('utf8');

client.net.on('data', function(response) {
    parser.parseString(response);
});

parser.addListener('end', function( xmlResponse ) {
    var response = xmlResponse['env:Envelope']['env:Header']['n:Response']._;
    /* handle Login response */
    if (response == 'Login'){
        /* make SOAP LoginContinue request */
        soapGps(xmlResponse, client, '');
    }
    /* handle LoginContinue response */
    if (response == 'LoginContinue') {
        if(xmlResponse['env:Envelope']['env:Body']['n:ResponseLoginContinue']['n:ErrCode'] == "ok") {           
            var nTimeMsecServer = xmlResponse['env:Envelope']['env:Body']['n:ResponseLoginContinue']['n:CurrentTime'];
            var nTimeMsecOur = new Date().getTime();
        } else {
            /* Unsuccessful login */
            io.to(client.id).emit('Error', "invalid login");
            client.net.destroy();
        }
    }
});

For windows

npm install -g grunt-cli

npm install load-grunt-tasks

Then run

grunt

Within a module, to have a combination of flavors, flavor resources (layout, values) and flavors resource resources, the main thing to keep in mind are two things:

1. When adding resource directories in res.srcDirs for flavor, keep in mind that in other modules and even in src/main/res of the same module, resource directories are also added. Hence, the importance of using an add-on assignment (+=) so as not to overwrite all existing resources with the new assignment.

2. The path that is declared as an element of the array is the one that contains the resource types, that is, the resource types are all the subdirectories that a res folder contains normally such as color, drawable, layout, values, etc. The name of the res folder can be changed.

An example would be to use the path "src/flavor/res/values/strings-ES" but observe that the practice hierarchy has to have the subdirectory values:

+-- module 
   +-- flavor
      +-- res
         +-- values
            +-- strings-ES
               +-- values
                  +-- strings.xml
               +-- strings.xml
 

The framework recognizes resources precisely by type, that is why normally known subdirectories cannot be omitted.

Also keep in mind that all the strings.xml files that are inside the flavor would form a union so that resources cannot be duplicated. And in turn this union that forms a file in the flavor has a higher order of precedence before the main of the module.

flavor {
        res.srcDirs += [
            "src/flavor/res/values/strings-ES"
        ]
}

Consider the strings-ES directory as a custom-res which contains the resource types.

Epoch reference date

An epoch reference date is a point on the timeline from which we count time. Moments before that point are counted with a negative number, moments after are counted with a positive number.

Many epochs in use

Why is 1 January 1970 00:00:00 considered the epoch time?

No, not the epoch, an epoch. There are many epochs in use.

This choice of epoch is arbitrary.

Major computers systems and libraries use any of at least a couple dozen various epochs. One of the most popular epochs is commonly known as Unix Time, using the 1970 UTC moment you mentioned.

While popular, Unix Time’s 1970 may not be the most common. Also in the running for most common would be January 0, 1900 for countless Microsoft Excel & Lotus 1-2-3 spreadsheets, or January 1, 2001 used by Apple’s Cocoa framework in over a billion iOS/macOS machines worldwide in countless apps. Or perhaps January 6, 1980 used by GPS devices?

Many granularities

Different systems use different granularity in counting time.

Even the so-called “Unix Time” varies, with some systems counting whole seconds and some counting milliseconds. Many database such as Postgres use microseconds. Some, such as the modern java.time framework in Java 8 and later, use nanoseconds. Some use still other granularities.

ISO 8601

Because there is so much variance in the use of an epoch reference and in the granularities, it is generally best to avoid communicating moments as a count-from-epoch. Between the ambiguity of epoch & granularity, plus the inability of humans to perceive meaningful values (and therefore miss buggy values), use plain text instead of numbers.

The ISO 8601 standard provides an extensive set of practical well-designed formats for expressing date-time values as text. These formats are easy to parse by machine as well as easy to read by humans across cultures.

These include:

• Date-only: 2019-01-23
• Moment in UTC: 2019-01-23T12:34:56.123456Z
• Moment with offset-from-UTC: 2019-01-23T18:04:56.123456+05:30
• Week of week-based-year: 2019-W23
• Ordinal date (1st to 366th day of year): 2019-234

You shouldn't use both ngRoute and UI-router. Here's a sample code for UI-router:

repoApp.config(function($stateProvider, $urlRouterProvider) {_x000D_
  _x000D_
  $stateProvider_x000D_
    .state('state1', {_x000D_
      url: "/state1",_x000D_
      templateUrl: "partials/state1.html",_x000D_
      controller: 'YourCtrl'_x000D_
    })_x000D_
    _x000D_
    .state('state2', {_x000D_
      url: "/state2",_x000D_
      templateUrl: "partials/state2.html",_x000D_
      controller: 'YourOtherCtrl'_x000D_
    });_x000D_
    $urlRouterProvider.otherwise("/state1");_x000D_
});_x000D_
//etc.

You can find a great answer on the difference between these two in this thread: What is the difference between angular-route and angular-ui-router?

You can also consult UI-Router's docs here: https://github.com/angular-ui/ui-router

Although they both are very much alike there is a minor difference :

var array = ["a", "b", "c"];
array["abc"] = 123;
console.log("Standard for loop:");
for (var index = 0; index < array.length; index++)
{
  console.log(" array[" + index + "] = " + array[index]); //Standard for loop
}

in this case the output is :

STANDARD FOR LOOP:

ARRAY[0] = A

ARRAY[1] = B

ARRAY[2] = C

console.log("For-in loop:");
for (var key in array)
{
  console.log(" array[" + key + "] = " + array[key]); //For-in loop output
}

while in this case the output is:

FOR-IN LOOP:

ARRAY[1] = B

ARRAY[2] = C

ARRAY[10] = D

ARRAY[ABC] = 123

set the target attribute of your <a> element to "_tab"

EDIT: It works, however W3Schools says there is no such target attribute: http://www.w3schools.com/tags/att_a_target.asp

EDIT2: From what I've figured out from the comments. setting target to _blank will take you to a new tab or window (depending on your browser settings). Typing anything except one of the ones below will create a new tab group (I'm not sure how these work):

_blank  Opens the linked document in a new window or tab
_self   Opens the linked document in the same frame as it was clicked (this is default)
_parent Opens the linked document in the parent frame
_top    Opens the linked document in the full body of the window
framename   Opens the linked document in a named frame

Here is a walkthrough, Using PostgreSQL in your C# (.NET) application (An introduction):

In this article, I would like to show you the basics of using a PostgreSQL database in your .NET application. The reason why I'm doing this is the lack of PostgreSQL articles on CodeProject despite the fact that it is a very good RDBMS. I have used PostgreSQL back in the days when PHP was my main programming language, and I thought.... well, why not use it in my C# application.

Other than that you will need to give us some specific problems that you are having so that we can help diagnose the problem.

@Josh Lindsey already answered perfectly fine. But I want to add some information since I often use ssh.

Therefore just change:

git remote add origin [email protected]:/path/to/my_project.git

to:

git remote add origin ssh://[email protected]/path/to/my_project

Note that the colon between domain and path isn't there anymore.

With SQL Server try:

SELECT TOP 1 * FROM dbo.youTable WHERE user_id = 'userid' ORDER BY date_added desc

What's the idiomatic syntax for prepending to a short python list?

You don't usually want to repetitively prepend to a list in Python.

If it's short, and you're not doing it a lot... then ok.

list.insert

The list.insert can be used this way.

list.insert(0, x)

But this is inefficient, because in Python, a list is an array of pointers, and Python must now take every pointer in the list and move it down by one to insert the pointer to your object in the first slot, so this is really only efficient for rather short lists, as you ask.

Here's a snippet from the CPython source where this is implemented - and as you can see, we start at the end of the array and move everything down by one for every insertion:

for (i = n; --i >= where; )
    items[i+1] = items[i];

If you want a container/list that's efficient at prepending elements, you want a linked list. Python has a doubly linked list, which can insert at the beginning and end quickly - it's called a deque.

deque.appendleft

A collections.deque has many of the methods of a list. list.sort is an exception, making deque definitively not entirely Liskov substitutable for list.

>>> set(dir(list)) - set(dir(deque))
{'sort'}

The deque also has an appendleft method (as well as popleft). The deque is a double-ended queue and a doubly-linked list - no matter the length, it always takes the same amount of time to preprend something. In big O notation, O(1) versus the O(n) time for lists. Here's the usage:

>>> import collections
>>> d = collections.deque('1234')
>>> d
deque(['1', '2', '3', '4'])
>>> d.appendleft('0')
>>> d
deque(['0', '1', '2', '3', '4'])

deque.extendleft

Also relevant is the deque's extendleft method, which iteratively prepends:

>>> from collections import deque
>>> d2 = deque('def')
>>> d2.extendleft('cba')
>>> d2
deque(['a', 'b', 'c', 'd', 'e', 'f'])

Note that each element will be prepended one at a time, thus effectively reversing their order.

Performance of list versus deque

First we setup with some iterative prepending:

import timeit
from collections import deque

def list_insert_0():
    l = []
    for i in range(20):
        l.insert(0, i)

def list_slice_insert():
    l = []
    for i in range(20):
        l[:0] = [i]      # semantically same as list.insert(0, i)

def list_add():
    l = []
    for i in range(20):
        l = [i] + l      # caveat: new list each time

def deque_appendleft():
    d = deque()
    for i in range(20):
        d.appendleft(i)  # semantically same as list.insert(0, i)

def deque_extendleft():
    d = deque()
    d.extendleft(range(20)) # semantically same as deque_appendleft above

and performance:

>>> min(timeit.repeat(list_insert_0))
2.8267281929729506
>>> min(timeit.repeat(list_slice_insert))
2.5210217320127413
>>> min(timeit.repeat(list_add))
2.0641671380144544
>>> min(timeit.repeat(deque_appendleft))
1.5863927800091915
>>> min(timeit.repeat(deque_extendleft))
0.5352169770048931

The deque is much faster. As the lists get longer, I would expect a deque to perform even better. If you can use deque's extendleft you'll probably get the best performance that way.

Seems like the safe way would be to use htons on each word. So, if you have...

std::vector<uint16_t> storage(n);  // where n is the number to be converted

// the following would do the trick
std::transform(word_storage.cbegin(), word_storage.cend()
  , word_storage.begin(), [](const uint16_t input)->uint16_t {
  return htons(input); });

The above would be a no-op if you were on a big-endian system, so I would look for whatever your platform uses as a compile-time condition to decide whether htons is a no-op. It is O(n) after all. On a Mac, it would be something like ...

#if (__DARWIN_BYTE_ORDER != __DARWIN_BIG_ENDIAN)
std::transform(word_storage.cbegin(), word_storage.cend()
  , word_storage.begin(), [](const uint16_t input)->uint16_t {
  return htons(input); });
#endif

You can set the internal field separator (IFS) variable, and then let it parse into an array. When this happens in a command, then the assignment to IFS only takes place to that single command's environment (to read ). It then parses the input according to the IFS variable value into an array, which we can then iterate over.

IFS=';' read -ra ADDR <<< "$IN"
for i in "${ADDR[@]}"; do
    # process "$i"
done

It will parse one line of items separated by ;, pushing it into an array. Stuff for processing whole of $IN, each time one line of input separated by ;:

 while IFS=';' read -ra ADDR; do
      for i in "${ADDR[@]}"; do
          # process "$i"
      done
 done <<< "$IN"

As I understand , all of previous answers , does not make an Array output, In my case : I have a model with parent-children structure (simplified code here):

public function parent(){

    return $this->belongsTo('App\Models\Accounting\accounting_coding', 'parent_id');
}


public function children()
{

    return $this->hasMany('App\Models\Accounting\accounting_coding', 'parent_id');
}

and if you want to have all of children IDs as an Array , This approach is fine and working for me :

public function allChildren()
{
    $allChildren = [];
    if ($this->has_branch) {

        foreach ($this->children as $child) {

            $subChildren = $child->allChildren();

            if (count($subChildren) == 1) {
                $allChildren  [] = $subChildren[0];
            } else if (count($subChildren) > 1) {
                $allChildren += $subChildren;
            }
        }
    }
    $allChildren  [] = $this->id;//adds self Id to children Id list

    return $allChildren; 
}

the allChildren() returns , all of childrens as a simple Array .

The answer is on the example link you provided:

http://getbootstrap.com/javascript/#modals-usage

i.e.

Call a modal with id myModal with a single line of JavaScript:

$('#myModal').modal('show');

GUI equivalent for hg commit --amend:

This also works from TortoiseHG's GUI (I'm using v2.5):

Swich to the 'Commit' view or, in the workbench view, select the 'working directory' entry. The 'Commit' button has an option named 'Amend current revision' (click the button's drop-down arrow to find it).

          ||
          ||
          \/

Caveat emptor:

This extra option will only be enabled if the mercurial version is at least 2.2.0, and if the current revision is not public, is not a patch and has no children. [...]

Clicking the button will call 'commit --amend' to 'amend' the revision.

In kotlin you could do it like this:

val backgroundColor = R.color.whatever_color_you_like
view.setBackgroundColor(getColorCompat(backgroundColor))

Where getColorCompat() is an extension function:

/**
 * Extension method to provide simpler access to {@link ContextCompat#getColor(int)}.
 */

 fun Context.getColorCompat(color: Int) = ContextCompat.getColor(this, color)

Also you are tying up a threadpool thread for the lifetime of the background worker, which may be of concern as there are only a finite number of them. I would say that if you are only ever creating the thread once for your app (and not using any of the features of background worker) then use a thread, rather than a backgroundworker/threadpool thread.

When doing this I found it easiest to:

1. Visit the page in a web browser
2. Save the page using the web browser with .htm extension (and maybe a folder with support files)
3. Start Word and open the saved htmfile (Word will open it correctly)
4. Make any edits if needed
5. Select Save As and then choose the extension you would like doc, docx, etc.

You need some form of iteration here, as val (except when called with a function) only works on the first element:

$("input[placeholder]").val($("input[placeholder]").attr("placeholder"));

should be:

$("input[placeholder]").each( function () {
    $(this).val( $(this).attr("placeholder") );
});

or

$("input[placeholder]").val(function() {
    return $(this).attr("placeholder");
});

If you need input from termial, try this

lc=`echo -n "xxx_${yyy}_iOS" |  base64`

-n option will not input "\n" character to base64 command.

You need both a value and a field to assign it to. The value is TableField + 1, so the assignment is:

SET TableField = TableField + 1

Short answer - Deleted .m2 folder in {user.home}. E.g. in windows 10 user home is C:\Users\user1. Re-build your project using mvn clean package. Only those dependencies would remain, which are required by the projects.

Long Answer - .m2 folder is just like a normal folder and the content of the folder is built from different projects. I think there is no way to figure out automatically that which library is "old". In fact old is a vague word. There could be so many reasons when a previous version of a library is used in a project, hence determining which one is unused is not possible.

All you could do, is to delete the .m2 folder and re-build all of your projects and then the folder would automatically build with all the required library.

If you are concern about only a particular version of a library to be used in all the projects; it is important that the project's pom should also update to latest version. i.e. if different POMs refer different versions of the library, all will get downloaded in .m2.

Go to Internet Explorer, into options -> connections -> Lan settings. There should be an automatic config script option, copy the url, paste it into a browser, this downloads the config file, opened the file up in notepad and there will be a proxy address and a port number in there like 192.234.10.23:88 paste the address into the proxy field and the port (88) into the port field in the Android SDK manager Tools -> Options dialog.

See if you have a file located under /etc/my.cnf. If so, it should tell you where the data directory is.

For example:

[mysqld]
set-variable=local-infile=0
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
...

My guess is that your mysql might be installed to /usr/local/mysql-XXX.

You may find these MySQL reference manual links useful:

• Installing MySQL 8.0 on MacOS
• Installing MySQL 5.7 on MacOS
• Installing MySQL 5.6 on MacOS
• Installing MySQL 5.5 on MacOS

To get this working with YAML, do this:

property-name: '{
  key1: "value1",
  key2: "value2"
}'

the htons() function converts values between host and network byte orders. There is a difference between big-endian and little-endian and network byte order depending on your machine and network protocol in use.

Swift version

This is the Swift version of David's Objective-C answer. You use the global queue to run things in the background and the main queue to update the UI.

DispatchQueue.global(qos: .background).async {
    
    // Background Thread
    
    DispatchQueue.main.async {
        // Run UI Updates
    }
}

You can use setInterval to create a progress bar.

function animate() {_x000D_
  var elem = document.getElementById("bar");   _x000D_
  var width = 1;_x000D_
  var id = setInterval(frame, 10);_x000D_
  function frame() {_x000D_
    if (width >= 100) {_x000D_
      clearInterval(id);_x000D_
    } else {_x000D_
      width++; _x000D_
      elem.style.width = width + '%'; _x000D_
    }_x000D_
  }_x000D_
}

#progress-bar-wrapper {_x000D_
  width: 100%;_x000D_
  background-color: #ddd;_x000D_
}_x000D_
_x000D_
#bar {_x000D_
  width: 1%;_x000D_
  height: 30px;_x000D_
  background-color: orange;_x000D_
}

<div id="progress-bar-wrapper">_x000D_
  <div id="bar"></div>_x000D_
</div>_x000D_
_x000D_
<br>_x000D_
<button onclick="animate()">Click Me</button>

Use package str2bool pip install str2bool

Using GET or POST is clearly explained by @LukLed. Regarding the ways you can pass the parameters I would suggest going with the second approach (I don't know much about ODATA either).

1.Serializing the params into one single JSON string and picking it apart in the API. http://forums.asp.net/t/1807316.aspx/1

This is not user friendly and SEO friendly

2.Pass the params in the query string. What is best way to pass multiple query parameters to a restful api?

This is the usual preferable approach.

3.Defining the params in the route: api/controller/date1/date2

This is definitely not a good approach. This makes feel some one date2 is a sub resource of date1 and that is not the case. Both the date1 and date2 are query parameters and comes in the same level.

In simple case I would suggest an URI like this,

api/controller?start=date1&end=date2

But I personally like the below URI pattern but in this case we have to write some custom code to map the parameters.

api/controller/date1,date2

Frequently we deal with other fellow java programmers work which create these Stored Procedure. and we do not want to mess around with it. but there is possibility you get the result set where these exec sample return 0 (almost Stored procedure call returning zero).

check this sample :

public void generateINOUT(String USER, int DPTID){

    try {


        conUrl = JdbcUrls + dbServers +";databaseName="+ dbSrcNames+";instance=MSSQLSERVER";

        con = DriverManager.getConnection(conUrl,dbUserNames,dbPasswords);
        //stat = con.createStatement();
        con.setAutoCommit(false); 
        Statement st = con.createStatement(); 

        st.executeUpdate("DECLARE @RC int\n" +
                "DECLARE @pUserID nvarchar(50)\n" +
                "DECLARE @pDepartmentID int\n" +
                "DECLARE @pStartDateTime datetime\n" +
                "DECLARE @pEndDateTime datetime\n" +
                "EXECUTE [AccessManager].[dbo].[SP_GenerateInOutDetailReportSimple] \n" +

                "," +DPTID+
                ",'"+STARTDATE +
                "','"+ENDDATE+"'");

        ResultSet rs = st.getGeneratedKeys();

        while (rs.next()){
              String userID = rs.getString("UserID");
              Timestamp timeIN = rs.getTimestamp("timeIN");
              Timestamp timeOUT = rs.getTimestamp ("timeOUT");
              int totTime = rs.getInt ("totalTime");
              int pivot = rs.getInt ("pivotvalue");

              timeINS = sdz.format(timeIN);
              userIN.add(timeINS);

              timeOUTS = sdz.format(timeOUT);
              userOUT.add(timeOUTS);

              System.out.println("User : "+userID+" |IN : "+timeIN+" |OUT : "+timeOUT+"| Total Time : "+totTime+" | PivotValue : "+pivot);
        }

        con.commit();

    }catch (Exception e) {
        e.printStackTrace();
        System.out.println(e);
        if (e.getCause() != null) {
        e.getCause().printStackTrace();}
    }  
}

check the query String I've done, that is your homework ;) so sorry answering this long, this is my first answer since I register few weeks ago to get answer.

$("#YourElementID").css("display","block");

Edit: or as dave thieben points out in his comment below, you can do this as well:

$("#YourElementID").css({ display: "block" });

context is where this refers to in your iterator function. For example:

var person = {};
person.friends = {
  name1: true,
  name2: false,
  name3: true,
  name4: true
};

_.each(['name4', 'name2'], function(name){
  // this refers to the friends property of the person object
  alert(this[name]);
}, person.friends);

function array_2_csv($array) {
    $csv = array();
    foreach ($array as $item) {
        if (is_array($item)) {
            $csv[] = array_2_csv($item);
        } else {
            $csv[] = $item;
        }
    }
    return implode(',', $csv);
} 

$csv_data = array_2_csv($array);

echo "<pre>";
print_r($csv_data);
echo '</pre>'   ; 

I had the same problem here... I tried to use destroy() and clear() method, but without success.

I resolved it the next way:

HTML:

<div id="pieChartContent">
    <canvas id="pieChart" width="300" height="300"></canvas>
</div>

Javascript:

var pieChartContent = document.getElementById('pieChartContent');
pieChartContent.innerHTML = ' ';
$('#pieChartContent').append('<canvas id="pieChart" width="300" height="300"><canvas>');

ctx = $("#pieChart").get(0).getContext("2d");        
var myPieChart = new Chart(ctx).Pie(data, options);

It works perfect to me... I hope that It helps.

If you are interessted in a more far-reaching solution to get all meta tags you could use this piece of code

function getAllMetas() {
    var metas = document.getElementsByTagName('meta');
    var summary = [];
    Array.from(metas)
        .forEach((meta) => {
            var tempsum = {};
            var attributes = meta.getAttributeNames();
            attributes.forEach(function(attribute) {
                tempsum[attribute] = meta.getAttribute(attribute);
            });
            summary.push(tempsum);
        });
    return summary;
}

// usage
console.log(getAllMetas());

I needed to do something similar and came across the same issues. I used the AfterSelect event to make sure I wasn't getting the previously selected node.

It's actually really easy to reference the correct node to receive the new child node.

private void TreeView1_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
   //show dialogbox to let user name the new node
   frmDialogInput f = new frmDialogInput();
   f.ShowDialog();

    //find the node that was selected
    TreeNode myNode = TreeView1.SelectedNode;
    //create the new node to add
    TreeNode newNode = new TreeNode(f.EnteredText);
    //add the new child to the selected node
    myNode.Nodes.Add(newNode);
}

A global variable would be best expressed in an external JavaScript file:

var system_status;

Make sure that this has not been used anywhere else. Then to access the variable on your page, just reference it as such. Say, for example, you wanted to fill in the results on a textbox,

document.getElementById("textbox1").value = system_status;

To ensure that the object exists, use the document ready feature of jQuery.

Example:

$(function() {
    $("#textbox1")[0].value = system_status;
});

To say that something "is null" means that it is a reference to the null value. Primitives (int, double, float, etc) are by definition not reference types, so they cannot have null values. You will need to find out what your database wrapper will do in this case.

go to your Controller write this in function

public function index()
{
  $posts = \App\Post::all();

  return view('yourview', ['posts' => $posts]);
}

in view to show it

@foreach($posts as $post)
  {{ $post->yourColumnName }}
@endforeach

In addition to the other answers here showing you how to git checkout <the-hash-you-want> it's worth knowing you can switch back to where you were using:

git checkout @{-1}

This is often more convenient than:

git checkout what-was-that-original-branch-called-again-question-mark

As you might anticipate, git checkout @{-2} will take you back to the branch you were at two git checkouts ago, and similarly for other numbers. If you can remember where you were for bigger numbers, you should get some kind of medal for that.

Sadly for productivity, git checkout @{1} does not take you to the branch you will be on in future, which is a shame.

I had the same issue since I changed my app ID in config.xml file.

I used to open my Android project by choosing among recent projects of Android Studio.

Just reading the file into an array, one line per element, is trivial:

open my $handle, '<', $path_to_file;
chomp(my @lines = <$handle>);
close $handle;

Now the lines of the file are in the array @lines.

If you want to make sure there is error handling for open and close, do something like this (in the snipped below, we open the file in UTF-8 mode, too):

my $handle;
unless (open $handle, "<:encoding(utf8)", $path_to_file) {
   print STDERR "Could not open file '$path_to_file': $!\n";
   # we return 'undefined', we could also 'die' or 'croak'
   return undef
}
chomp(my @lines = <$handle>);
unless (close $handle) {
   # what does it mean if close yields an error and you are just reading?
   print STDERR "Don't care error while closing '$path_to_file': $!\n";
} 

Below is the method using RouteData to style menuBar items depending of the current route:

RouteConfig includes data with tab (current route):

@RouteConfig([
  {
    path: '/home',    name: 'Home',    component: HomeComponent,
    data: {activeTab: 'home'},  useAsDefault: true
  }, {
    path: '/jobs',    name: 'Jobs',    data: {activeTab: 'jobs'},
    component: JobsComponent
  }
])

A piece of layout:

  <li role="presentation" [ngClass]="{active: isActive('home')}">
    <a [routerLink]="['Home']">Home</a>
  </li>
  <li role="presentation" [ngClass]="{active: isActive('jobs')}">
    <a [routerLink]="['Jobs']">Jobs</a>
  </li>

Class:

export class MainMenuComponent {
  router: Router;

  constructor(data: Router) {
    this.router = data;
  }

  isActive(tab): boolean {
    if (this.router.currentInstruction && this.router.currentInstruction.component.routeData) {
      return tab == this.router.currentInstruction.component.routeData.data['activeTab'];
    }
    return false;
  }
}

The question is bigger than just using wither static_cast or C style casting because there are different things that happen when using C style casts. The C++ casting operators are intended to make these operations more explicit.

On the surface static_cast and C style casts appear to the same thing, for example when casting one value to another:

int i;
double d = (double)i;                  //C-style cast
double d2 = static_cast<double>( i );  //C++ cast

Both of these cast the integer value to a double. However when working with pointers things get more complicated. some examples:

class A {};
class B : public A {};

A* a = new B;
B* b = (B*)a;                                  //(1) what is this supposed to do?

char* c = (char*)new int( 5 );                 //(2) that weird?
char* c1 = static_cast<char*>( new int( 5 ) ); //(3) compile time error

In this example (1) maybe OK because the object pointed to by A is really an instance of B. But what if you don't know at that point in code what a actually points to? (2) maybe perfectly legal(you only want to look at one byte of the integer), but it could also be a mistake in which case an error would be nice, like (3). The C++ casting operators are intended to expose these issues in the code by providing compile-time or run-time errors when possible.

So, for strict "value casting" you can use static_cast. If you want run-time polymorphic casting of pointers use dynamic_cast. If you really want to forget about types, you can use reintrepret_cast. And to just throw const out the window there is const_cast.

They just make the code more explicit so that it looks like you know what you were doing.

If you use different version of play services libraries, you will get this error.

For example, below entries in build.gradle file cause the error as versions are different.

implementation 'com.google.android.gms:play-services-maps:11.4.2'
implementation 'com.google.android.gms:play-services-location:11.6.0'

To fix the issue use same versions.

implementation 'com.google.android.gms:play-services-maps:11.6.0'
implementation 'com.google.android.gms:play-services-location:11.6.0'

I have that kind of spring setup working

an abstract class with an autowired field

public abstract class AbstractJobRoute extends RouteBuilder {

    @Autowired
    private GlobalSettingsService settingsService;

and several children defined with @Component annotation.

Correct way to check for null or empty or string containing only spaces is like this:

if(str != null && !str.trim().isEmpty()) { /* do your stuffs here */ }

I think so.. it's possible to 'bind' custom events, like(from: http://docs.jquery.com/Events/bind#typedatafn):

 $("p").bind("myCustomEvent", function(e, myName, myValue){
      $(this).text(myName + ", hi there!");
      $("span").stop().css("opacity", 1)
               .text("myName = " + myName)
               .fadeIn(30).fadeOut(1000);
    });
    $("button").click(function () {
      $("p").trigger("myCustomEvent", [ "John" ]);
    });

pretty old topic but this is maybe a help for someone searching for the problem where the above tips does not solved it.

I use

git credential-manager remove -force

INSERT INTO dues_storage
SELECT field1, field2, ..., fieldN, CURRENT_DATE()
FROM dues
WHERE id = 5;

In this particular case, due to the dangers cited in other answers, I would

1. Edit in e.g. Vim and :%s/\s/\\\0/g, escaping all space characters with a backslash.

2. Then :%s/^/rm -rf /, prepending the command. With -r you don't have to worry to have directories listed after the files contained therein, and with -f it won't complain due to missing files or duplicate entries.

3. Run all the commands: $ source 1.txt

class B is only declared but not defined at the beginning, which is what the compiler complains about. The root cause is that in class A's Call Function, you are referencing instance b of type B, which is incomplete and undefined. You can modify source like this without introducing new file(just for sake of simplicity, not recommended in practice):

using namespace std;

class A 
{
public:

    void CallFunction ();
};

class B: public A
{
public:
    virtual void bFunction()
    {
        //stuff done here
    }
};


 // postpone definition of CallFunction here

 void A::CallFunction ()
 {
     B b;
     b.bFunction();
 }

Check your Internet connection. If internet speed is very slow gradle build will also take long time to build. I check by change my wifi internet connection with another one good speed connection. Now build time is normal. Please try this before you go to other solutions. somebody will take wrong decision to reinstall or change settings. I hope it will help. Thanks and regards.

For completeness sake, also a solution with Joda-Time version 2.5 and its DateTime class:

new Timestamp(new DateTime(2007, 9, 23, 0, 0, DateTimeZone.forID( "America/Montreal" )).getMillis())

onChange is when something within a field changes eg, you write something in a text input.

onBlur is when you take focus away from a field eg, you were writing in a text input and you have clicked off it.

So really they are almost the same thing but for onChange to behave the way onBlur does something in that input needs to change.

Check your internet settings, firewalls and such may be blocking it, I know when I was working on it in college they were blocking the port number but I've never had any trouble on my home machines

I am just answering here with the formatted version of the final sql I needed based on Bob Jarvis answer as posted in my comment above:

select n1.name, n1.author_id, cast(count_1 as numeric)/total_count
  from (select id, name, author_id, count(1) as count_1
          from names
          group by id, name, author_id) n1
inner join (select author_id, count(1) as total_count
              from names
              group by author_id) n2
  on (n2.author_id = n1.author_id)

The syntax is

pid_t waitpid(pid_t pid, int *statusPtr, int options);

1.where pid is the process of the child it should wait.

2.statusPtr is a pointer to the location where status information for the terminating process is to be stored.

3.specifies optional actions for the waitpid function. Either of the following option flags may be specified, or they can be combined with a bitwise inclusive OR operator:

WNOHANG WUNTRACED WCONTINUED

If successful, waitpid returns the process ID of the terminated process whose status was reported. If unsuccessful, a -1 is returned.

benifits over wait

1.Waitpid can used when you have more than one child for the process and you want to wait for particular child to get its execution done before parent resumes

2.waitpid supports job control

3.it supports non blocking of the parent process

Here is how to clear all trash & caches (without other private data in browsers) by a command line. This is a command line batch script that takes care of all trash (as of April 2014):

erase "%TEMP%\*.*" /f /s /q

erase "%TMP%\*.*" /f /s /q
for /D %%i in ("%TMP%\*") do RD /S /Q "%%i"

erase "%ALLUSERSPROFILE%\TEMP\*.*" /f /s /q
for /D %%i in ("%ALLUSERSPROFILE%\TEMP\*") do RD /S /Q "%%i"

erase "%SystemRoot%\TEMP\*.*" /f /s /q
for /D %%i in ("%SystemRoot%\TEMP\*") do RD /S /Q "%%i"


@rem Clear IE cache -  (Deletes Temporary Internet Files Only)

I am pretty sure it will run for some time when you first run it :) Enjoy!

It says "POST not supported", so the request is not calling your servlet. If I were you, I will issue a GET (e.g. access using a browser) to the exact URL you are issuing your POST request, and see what you get. I bet you'll see something unexpected.

You might need to set GEM_HOME for the cleanup to work. You can check what paths exist for gemfiles by running:

gem env

Take note of the GEM PATHS section.

In my case, for example, with gems installed in my user home:

export GEM_HOME="~/.gem/ruby/2.4.0"
gem cleanup

Looking in the headers sent...
res.send uses content-type:text/html
res.json uses content-type:application/json

edit: send actually changes what is sent based on what it's given, so strings are sent as text/html, but it you pass it an object it emits application/json.

You just need to do:

#!/bin/bash
count=$(cat last_queries.txt | wc -l)
$(perl test.pl test2 $count)

However, if you want to call your Perl command later, and that's why you want to assign it to a variable, then:

#!/bin/bash
count=$(cat last_queries.txt | wc -l)
var="perl test.pl test2 $count" # You need double quotes to get your $count value substituted.

...stuff...

eval $var

As per Bash's help:

~$ help eval
eval: eval [arg ...]
    Execute arguments as a shell command.

    Combine ARGs into a single string, use the result as input to the shell,
    and execute the resulting commands.

    Exit Status:
    Returns exit status of command or success if command is null.

git pull and git rebase are not interchangeable, but they are closely connected.

git pull fetches the latest changes of the current branch from a remote and applies those changes to your local copy of the branch. Generally this is done by merging, i.e. the local changes are merged into the remote changes. So git pull is similar to git fetch & git merge.

Rebasing is an alternative to merging. Instead of creating a new commit that combines the two branches, it moves the commits of one of the branches on top of the other.

You can pull using rebase instead of merge (git pull --rebase). The local changes you made will be rebased on top of the remote changes, instead of being merged with the remote changes.

Atlassian has some excellent documentation on merging vs. rebasing.

go

Usage:

declare @liststr varchar(max)
select @liststr = dbo.group_concat_d(institutionname, ',')
from education
where studentnumber = '111'
group by studentnumber;
select @liststr

GroupConcat does not support ordering, though. You could use PIVOT, CTE's and windows functions if you need ordering:

drop table if exists #students;
create table #students (
    name        varchar(20),
    institution varchar(20),
    year        int -- order by year
)
go

insert into #students(name, institution, year)
values
    ('Simon', 'INSTITUTION1', 2005),
    ('Simon', 'INSTITUTION2', 2008);

with cte as (
    select name,
           institution,
           rn = row_number() over (partition by name order by year)
    from #students
)
select name,
       [1] +
       isnull((',' + [2]), '') +
       isnull((',' + [3]), '') +
       isnull((',' + [4]), '') +
       isnull((',' + [5]), '') +
       isnull((',' + [6]), '') +
       isnull((',' + [7]), '') +
       isnull((',' + [8]), '') +
       isnull((',' + [9]), '') +
       isnull((',' + [10]), '') +
       isnull((',' + [11]), '') +
       isnull((',' + [12]), '') +
       isnull((',' + [13]), '') +
       isnull((',' + [14]), '') +
       isnull((',' + [15]), '') +
       isnull((',' + [16]), '') +
       isnull((',' + [17]), '') +
       isnull((',' + [18]), '') +
       isnull((',' + [19]), '') +
       isnull((',' + [20]), '')
from cte
    pivot (
    max(institution)
    for rn in ([1], [2], [3], [4],[5],[6],[7],[8],[9],[10],[11],[12],[13],[14],[15],[16],[17],[18],[19],[20])
    ) as piv

There is a pretty good example on https://developers.google.com/maps/documentation/javascript/examples/geocoding-simple

To shorten it up a little:

geocoder = new google.maps.Geocoder();

function codeAddress() {

    //In this case it gets the address from an element on the page, but obviously you  could just pass it to the method instead
    var address = document.getElementById( 'address' ).value;

    geocoder.geocode( { 'address' : address }, function( results, status ) {
        if( status == google.maps.GeocoderStatus.OK ) {

            //In this case it creates a marker, but you can get the lat and lng from the location.LatLng
            map.setCenter( results[0].geometry.location );
            var marker = new google.maps.Marker( {
                map     : map,
                position: results[0].geometry.location
            } );
        } else {
            alert( 'Geocode was not successful for the following reason: ' + status );
        }
    } );
}

Easiest thing is input it as a "div" give it a "margin:0 auto " but if you want it to be centered u need to give it a width

  Div{
   Margin: 0 auto ;
   Width: 100px ;
  }

Simply Add 'carousel-item' class in place of item class.

Although Marcelo's solution seems to be working great, you may not need to download the font at all! Just link to it remotely.

E.g the font is hosted on example.com, do

@font-face {
  font-family: "Font Name";
  font-style: normal;
  src: url(http://example.com/webfonts/font-name.woff);
}

You may easily figure out the direct url to the font by looking into css code from example.com and see how they linked the file.

The problem is that jQuery doesn't trigger the native click event for <a> elements so that navigation doesn't happen (the normal behavior of an <a>), so you need to do that manually. For almost all other scenarios, the native DOM event is triggered (at least attempted to - it's in a try/catch).

To trigger it manually, try:

var a = $("<a>")
    .attr("href", "http://i.stack.imgur.com/L8rHf.png")
    .attr("download", "img.png")
    .appendTo("body");

a[0].click();

a.remove();

DEMO: http://jsfiddle.net/HTggQ/

Relevant line in current jQuery source: https://github.com/jquery/jquery/blob/1.11.1/src/event.js#L332

if ( (!special._default || special._default.apply( eventPath.pop(), data ) === false) &&
        jQuery.acceptData( elem ) ) {

Windows:

<workspace>\.metadata\.plugins\org.eclipse.core.resources\.projects\

Linux / osx:

<workspace>/.metadata/.plugins/org.eclipse.core.resources/.projects/

Your project can exist outside the workspace, but all Eclipse-specific metadata are stored in that org.eclipse.core.resources\.projects directory

The problem isn't that null cannot be assigned to an int?. The problem is that both values returned by the ternary operator must be the same type, or one must be implicitly convertible to the other. In this case, null cannot be implicitly converted to int nor vice-versus, so an explict cast is necessary. Try this instead:

int? accom = (accomStr == "noval" ? (int?)null : Convert.ToInt32(accomStr));

You could also try this:

SELECT DISTINCT (DATE(dateadded)) AS unique_date, COUNT(*) AS amount
FROM table
GROUP BY unique_date
ORDER BY unique_date ASC

Short oneliner for CamelCases when you have spaces also included (doesn't work correctly if you have a word inbetween with small starting-letter):

a = "Test String"
a.gsub(' ', '').underscore

  => "test_string"

Sqlldr wants to write a log file in the same directory where the control file is. But obviously it can't. It probably doesn't have the required permission.

If you're on Linux or Unix, try to run the following command the same way you run sqldr:

touch Billing.log

It will show whether you have the permissions.

Update

The proper command line is:

sqlldr myusername/mypassword control=Billing.ctl

Anybody working with nullable types, Value is required to use CompareTo.

objListOrder.Sort((x, y) => x.YourNullableType.Value.CompareTo(y.YourNullableType.Value));

In an Excel pivot table, you are correct that a filter only allows values that are explicitly selected. If the filter field is placed on the pivot table rows or columns, however, you get a much wider set of Label Filter conditions, including Greater Than. If you did that in your case, then the added benefit would be that the various probability levels that match your condition are shown in the body of the table.

Here is a way to do it without adding an ID to the form elements.

<form method="post">
    ...
    <select name="List">
        <option value="1">Test1</option>
        <option value="2">Test2</option>
    </select>
    <select name="List">
        <option value="3">Test3</option>
        <option value="4">Test4</option>
    </select>
    ...
</form>

public ActionResult OrderProcessor()
{
    string[] ids = Request.Form.GetValues("List");
}

Then ids will contain all the selected option values from the select lists. Also, you could go down the Model Binder route like so:

public class OrderModel
{
    public string[] List { get; set; }

Hope this helps.

Same with something more complex...getting the ec2 instance region from within the instance.

INSTANCE_REGION=$(curl -s 'http://169.254.169.254/latest/dynamic/instance-identity/document' | python -c "import sys, json; print json.load(sys.stdin)['region']")

echo $INSTANCE_REGION

Fancybox 2.x at least has an "overlay helper" which turned out to be the key for me. I added the following to my fancybox configuration parameters:

helpers : {
  overlay : {
    css : { 'overlay' : 'hidden' }
  }
}

I had tried setting this in the CSS, but that didn't work, and late in the game, such as on the beforeShow event, but that led to a flickering bar. This seems to work without a hitch.

Erm is there any reason why you can't just use the HttpRequest? This would be on the server side but you could pass it to the javascript if you needed to?

Page.Request.UserHostName

HttpRequest.UserHostName

The one problem with this is it would only really work in an Intranet environment otherwise it would just end up picking up the users Router or Proxy address...

Most of the other answers are simply concatenating their HTML body with the HTML signature. However, this does not work with images, and it turns out there is a more "standard" way of doing this.1

Microsoft Outlook pre-2007 which is configured with WordEditor as its editor, and Microsoft Outlook 2007 and beyond, use a slightly cut-down version of the Word Editor to edit emails. This means we can use the Microsoft Word Document Object Model to make changes to the email.

Set objMsg = Application.CreateItem(olMailItem)
objMsg.GetInspector.Display 'Displaying an empty email will populate the default signature
Set objSigDoc = objMsg.GetInspector.WordEditor
Set objSel = objSigDoc.Windows(1).Selection
With objSel
   .Collapse wdCollapseStart
   .MoveEnd WdUnits.wdStory, 1
   .Copy 'This will copy the signature
End With
objMsg.HTMLBody = "<p>OUR HTML STUFF HERE</p>"
With objSel
   .Move WdUnits.wdStory, 1 'Move to the end of our new message
   .PasteAndFormat wdFormatOriginalFormatting 'Paste the copied signature
End With

Methods addOption(data) and setValue(value) might be what you are looking for.

Update: Seeing the popularity of this answer, here is some additional info based on comments/requests...

setValue(value, silent)
Resets the selected items to the given value.
If "silent" is truthy (ie: true, 1), no change event will be fired on the original input.

addOption(data)
Adds an available option, or array of options. If it already exists, nothing will happen.
Note: this does not refresh the options list dropdown (use refreshOptions() for that).

In response to options being overwritten:
This can happen by re-initializing the select without using the options you initially provided. If you are not intending to recreate the element, simply store the selectize object to a variable:

// 1. Only set the below variables once (ideally)
var $select = $('select').selectize(options);  // This initializes the selectize control
var selectize = $select[0].selectize; // This stores the selectize object to a variable (with name 'selectize')

// 2. Access the selectize object with methods later, for ex:
selectize.addOption(data);
selectize.setValue('something', false);


// Side note:
// You can set a variable to the previous options with
var old_options = selectize.settings;
// If you intend on calling $('select').selectize(old_options) or something

You partial looks much like an editor template so you could include it as such (assuming of course that your partial is placed in the ~/views/controllername/EditorTemplates subfolder):

@Html.EditorFor(model => model.SomePropertyOfTypeLocaleBaseModel)

Or if this is not the case simply:

@Html.Partial("nameOfPartial", Model)

I think you are confused about how the compiler puts things together. When you use -c flag, i.e. no linking is done, the input is C++ code, and the output is object code. The .o files thus don't mix with -c, and compiler warns you about that. Symbols from object file are not moved to other object files like that.

All object files should be on the final linker invocation, which is not the case here, so linker (called via g++ front-end) complains about missing symbols.

Here's a small example (calling g++ explicitly for clarity):

PROG ?= myprog
OBJS = worker.o main.o

all: $(PROG)

.cpp.o:
        g++ -Wall -pedantic -ggdb -O2 -c -o $@ $<

$(PROG): $(OBJS)
        g++ -Wall -pedantic -ggdb -O2 -o $@ $(OBJS)

There's also makedepend utility that comes with X11 - helps a lot with source code dependencies. You might also want to look at the -M gcc option for building make rules.

The quick answer is 2^16 TCP ports, 64K.

The issues with system imposed limits is a configuration issue, already touched upon in previous comments.

The internal implications to TCP is not so clear (to me). Each port requires memory for it's instantiation, goes onto a list and needs network buffers for data in transit.

Given 64K TCP sessions the overhead for instances of the ports might be an issue on a 32-bit kernel, but not a 64-bit kernel (correction here gladly accepted). The lookup process with 64K sessions can slow things a bit and every packet hits the timer queues, which can also be problematic. Storage for in transit data can theoretically swell to the window size times ports (maybe 8 GByte).

The issue with connection speed (mentioned above) is probably what you are seeing. TCP generally takes time to do things. However, it is not required. A TCP connect, transact and disconnect can be done very efficiently (check to see how the TCP sessions are created and closed).

There are systems that pass tens of gigabits per second, so the packet level scaling should be OK.

There are machines with plenty of physical memory, so that looks OK.

The performance of the system, if carefully configured should be OK.

The server side of things should scale in a similar fashion.

I would be concerned about things like memory bandwidth.

Consider an experiment where you login to the local host 10,000 times. Then type a character. The entire stack through user space would be engaged on each character. The active footprint would likely exceed the data cache size. Running through lots of memory can stress the VM system. The cost of context switches could approach a second!

This is discussed in a variety of other threads: https://serverfault.com/questions/69524/im-designing-a-system-to-handle-10000-tcp-connections-per-second-what-problems

I just came up with this method which may be hardware intensive but it is working:

You can replace all characters which match the regex by an empty string.

This is a oneliner:

notMatched = re.sub(regex, "", string)

I used this because I was forced to use a very complex regex and couldn't figure out how to invert every part of it within a reasonable amount of time.

This will only return you the string result, not any match objects!

I have had to do this for a small Node.js project and found this work-around:

{
 "modify_head": [

  "<script type='text/javascript'>",
  "<!--",
  "  function drawSomeText(id) {",
  "  var pjs = Processing.getInstanceById(id);",
  "  var text = document.getElementById('inputtext').value;",
  "  pjs.drawText(text);}",
  "-->",
  "</script>"

 ],

 "modify_body": [

  "<input type='text' id='inputtext'></input>",
  "<button onclick=drawSomeText('ExampleCanvas')></button>"

 ],
}

This looks quite neat to me, appart from that I have to use double quotes everywhere. Though otherwise, I could, perhaps, use YAML, but that has other pitfalls and is not supported natively. Once parsed, I just use myData.modify_head.join('\n') or myData.modify_head.join(), depending upon whether I want a line break after each string or not.

If you're using GNU find,

find . -mtime 1 -exec cp -t ~/test/ {} +

This works as well as piping the output into xargs while avoiding the pitfalls of doing so (it handles embedded spaces and newlines without having to use find ... -print0 | xargs -0 ...).

You can also use hostbinding:

import { HostBinding } from '@angular/core';

export class HomeComponent {
    @HostBinding('style.width') width: Number;
    @HostBinding('style.height') height: Number;
} 

Now when you change the width or height property from within the HomeComponent, this should affect the style attributes.

This can also be done with a timeout:

# Ping until timeout or 1 successful packet
ping -w (timeout) -c 1

This code is working fine for me in a loop

$remove = array(
    "market_value",
    "sector_id"
);

foreach($remove as $key){
    unset($obj_name->$key);
}

"more custom" than CSS cursors means a plugin of some type, but you can totally specify your own cursors using CSS. I think this list has what you want:

So you can use:

myvar = getURLParameter('myvar');

This might be like resurrecting a dead horse. But just so it's out there, the reason why the answer to these types of questions to simply put dll's into the system32 folder is because that folder is in the os's system path.

It's actually best practice to provide the os with a path link.

With windows 10

1. open up file explorer
2. right click on "this pc" and select "properties"
3. Now in the "Control Panel\System and Security\System" window that comes up, click on "Advanced System Settings" from the left hand panel.
4. At the bottom of the next window, click on the "Environment Variables" button.
5. On the next window, there are two panels, the top one is for modifying variables to the current user, and the bottom panel is for modifying variables to the system. On the bottom panel, find the variable "Path" and click it to select it, then click on the "edit" button.
6. Here you can then create, edit, delete, or update the different paths for the system. For example, to add mingw32-make to the system so you can access that command via command prompt, click new, then paste in the path to the bin. Example path, "D:\Qt\Tools\mingw730_64\bin", no quotation marks nor additional whitespaces.
7. Click ok on all the windows so that the changes are saved, then reboot your computer for the changes to be loaded.

Here's one that creates a multidimensional array sorted by offset and niceified name:

function timezones() {
    $timezones = [];

    foreach (timezone_identifiers_list() as $timezone) {
        $datetime = new \DateTime('now', new DateTimeZone($timezone));
        $timezones[] = [
            'sort' => str_replace(':', '', $datetime->format('P')),
            'offset' => $datetime->format('P'),
            'name' => str_replace('_', ' ', implode(', ', explode('/', $timezone))),
            'timezone' => $timezone,
        ];
    }

    usort($timezones, function($a, $b) {
        return $a['sort'] - $b['sort'] ?: strcmp($a['name'], $b['name']);
    });

    return $timezones;
}

foreach (timezones() as $timezone) {
    echo '(UTC '.$timezone['offset'].') '.$timezone['name'].'<br>';
}

Another alternative: you can check if an item is in a list with if item in list:, but this is order O(n). If you are dealing with big lists of items and all you need to know is whether something is a member of your list, you can convert the list to a set first and take advantage of constant time set lookup:

my_set = set(my_list)
if item in my_set:  # much faster on average than using a list
    # do something

Not going to be the correct solution in every case, but for some cases this might give you better performance.

Note that creating the set with set(my_list) is also O(n), so if you only need to do this once then it isn't any faster to do it this way. If you need to repeatedly check membership though, then this will be O(1) for every lookup after that initial set creation.

Update: I have found a better/proper way to solve this problem using a BehaviorSubject or an Observable rather than an EventEmitter. Please see this answer: https://stackoverflow.com/a/35568924/215945

Also, the Angular docs now have a cookbook example that uses a Subject.

Original/outdated/wrong answer: again, don't use an EventEmitter in a service. That is an anti-pattern.

Using beta.1... NavService contains the EventEmiter. Component Navigation emits events via the service, and component ObservingComponent subscribes to the events.

nav.service.ts

import {EventEmitter} from 'angular2/core';
export class NavService {
  navchange: EventEmitter<number> = new EventEmitter();
  constructor() {}
  emitNavChangeEvent(number) {
    this.navchange.emit(number);
  }
  getNavChangeEmitter() {
    return this.navchange;
  }
}

components.ts

import {Component} from 'angular2/core';
import {NavService} from '../services/NavService';

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number = 0;
  subscription: any;
  constructor(private navService:NavService) {}
  ngOnInit() {
    this.subscription = this.navService.getNavChangeEmitter()
      .subscribe(item => this.selectedNavItem(item));
  }
  selectedNavItem(item: number) {
    this.item = item;
  }
  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
    <div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>
  `,
})
export class Navigation {
  item = 1;
  constructor(private navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this.navService.emitNavChangeEvent(item);
  }
}

Plunker

First of all, we can't really remove all null conditions. We can reduce them using @NotNull and @Nullable annotations (as mentioned already). But this needs to be backed by some framework. This is where OVal can help.

The basic idea is object/parameters/constructor should always satisfy preconditions. You can have a whole lot of preconditions such as Nullable, NotNull and OVal would take care that an object should be in a consistent state when invoked.

I guess OVal internally uses AspectJ to validate the preconditions.

@Guarded
public class BusinessObject
{
  public BusinessObject(@NotNull String name)
  {
    this.name = name;
  }

  ...
}

For example,

// Throws a ConstraintsViolatedException because parameter name is null
BusinessObject bo = new BusinessObject(null);

maybe you forget to add parameter dataType:'json' in your $.ajax

$.ajax({
   type: "POST",
   dataType: "json",
   url: url,
   data: { get_member: id },
   success: function( response ) 
   { 
     //some action here
   },
   error: function( error )
   {
     alert( error );
   }
});

For the image that is not showing up. Open the image in the Image editor and check the type you are probably name it as "gif" but its saved in a different format that's one reason that the browser is unable to render it and it is not showing.
For the image stretching issue please specify the actual width and height dimensions in #banner instead of width: 100%; height: 200px that you have specified.

(Note: although the cloning version is potentially useful, for a simple shallow copy the constructor I mention in the other post is a better option.)

How deep do you want the copy to be, and what version of .NET are you using? I suspect that a LINQ call to ToDictionary, specifying both the key and element selector, will be the easiest way to go if you're using .NET 3.5.

For instance, if you don't mind the value being a shallow clone:

var newDictionary = oldDictionary.ToDictionary(entry => entry.Key,
                                               entry => entry.Value);

If you've already constrained T to implement ICloneable:

var newDictionary = oldDictionary.ToDictionary(entry => entry.Key, 
                                               entry => (T) entry.Value.Clone());

(Those are untested, but should work.)

This function will reorder your columns without losing data. Any omitted columns remain in the center of the data set:

def reorder_columns(columns, first_cols=[], last_cols=[], drop_cols=[]):
    columns = list(set(columns) - set(first_cols))
    columns = list(set(columns) - set(drop_cols))
    columns = list(set(columns) - set(last_cols))
    new_order = first_cols + columns + last_cols
    return new_order

Example usage:

my_list = ['first', 'second', 'third', 'fourth', 'fifth', 'sixth']
reorder_columns(my_list, first_cols=['fourth', 'third'], last_cols=['second'], drop_cols=['fifth'])

# Output:
['fourth', 'third', 'first', 'sixth', 'second']

To assign to your dataframe, use:

my_list = df.columns.tolist()
reordered_cols = reorder_columns(my_list, first_cols=['fourth', 'third'], last_cols=['second'], drop_cols=['fifth'])
df = df[reordered_cols]

You can also get this error by prematurely taking PyCharm's advice to annotate a method @staticmethod. Remove the annotation.

System Preferences => Keyboard => Key Repeat Rate

Assert is very useful when developing. You use it when something just cannot happen if your code is working correctly. It's easy to use, and can stay in the code for ever, because it will be turned off in real life.

If there is any chance that the condition can occur in real life, then you must handle it.

I love it, but don't know how to turn it on in Eclipse/Android/ADT . It seems to be off even when debugging. (There is a thread on this, but it refers to the 'Java vm', which does not appear in the ADT Run Configuration).

>>> l = [list(range(i, i+4)) for i in range(10,1,-1)]
>>> l
[[10, 11, 12, 13], [9, 10, 11, 12], [8, 9, 10, 11], [7, 8, 9, 10], [6, 7, 8, 9], [5, 6, 7, 8], [4, 5, 6, 7], [3, 4, 5, 6], [2, 3, 4, 5]]
>>> sorted(l, key=sum)
[[2, 3, 4, 5], [3, 4, 5, 6], [4, 5, 6, 7], [5, 6, 7, 8], [6, 7, 8, 9], [7, 8, 9, 10], [8, 9, 10, 11], [9, 10, 11, 12], [10, 11, 12, 13]]

The above works. Are you doing something different?

Notice that your key function is just sum; there's no need to write it explicitly.

            paint.setStyle(Paint.Style.FILL);
            paint.setColor(Color.WHITE);
            canvas.drawPaint(paint);
            // Use Color.parseColor to define HTML colors
            paint.setColor(Color.parseColor("#CD5C5C"));
            canvas.drawCircle(x / 2, y / 2, radius, paint);
        }
     }
}

Edit if you want to draw circle at centre. You could also translate your entire canvas to center then draw circle at center.using

canvas.translate(getWidth()/2f,getHeight()/2f);
canvas.drawCircle(0,0, radius, paint);

It needs to work with the transparent background in a spinner.

In my case everything solved after re-cloning the repo and launching it again.

Setup: Xcode 12.4 Mac M1

The distinction between "self" and "cls" is defined in PEP 8 . As Adrien said, this is not a mandatory. It's a coding style. PEP 8 says:

Function and method arguments:

Always use self for the first argument to instance methods.

Always use cls for the first argument to class methods.

it is because of using web address, You can not use http to write data. don't use : http:// or https:// in your location for upload files or save data or somting like that. instead of of using $_SERVER["HTTP_REFERER"] use $_SERVER["DOCUMENT_ROOT"]. for example :

wrong :

move_uploaded_file($_FILES["File"]["tmp_name"],$_SERVER["HTTP_REFERER"].'/uploads/images/1.jpg')

correct:

move_uploaded_file($_FILES["File"]["tmp_name"],$_SERVER["DOCUMENT_ROOT"].'/uploads/images/1.jpg')

only in a case in serializer things, you can update in very simple way!

my_model_serializer = MyModelSerializer(
    instance=my_model, data=validated_data)
if my_model_serializer.is_valid():

    my_model_serializer.save()

only in a case in form things!

instance = get_object_or_404(MyModel, id=id)
form = MyForm(request.POST or None, instance=instance)
if form.is_valid():
    form.save()

The right solution is to use grep -v "word" file, with its awk equivalent:

awk '!/word/' file

However, if you happen to have a more complex situation in which you want, say, XXX to appear and YYY not to appear, then awk comes handy instead of piping several greps:

awk '/XXX/ && !/YYY/' file
#    ^^^^^    ^^^^^^
# I want it      |
#            I don't want it

You can even say something more complex. For example: I want those lines containing either XXX or YYY, but not ZZZ:

awk '(/XXX/ || /YYY/) && !/ZZZ/' file

etc.
