Generally, I think your USB connection should be set to use MTP (Media Transfer), however, I couldn't get my computer to recognize my device (Nexus 4). Oddly, setting the USB connection to Camera got it working for me.

For using scroll view along with Relative layout :

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:fillViewport="true"> <!--IMPORTANT otherwise backgrnd img. will not fill the whole screen -->

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        android:background="@drawable/background_image"
    >

    <!-- Bla Bla Bla i.e. Your Textviews/Buttons etc. -->
    </RelativeLayout>
</ScrollView>

Here is what you can do if you want to add a column of numbers in Excel. ( I am using Excel 2010 but should not make a difference.)

Example: Lets say you want to add the cells in Column B form B10 to B100 & want the answer to be in cell X or be Variable X ( X can be any cell or any variable you create such as Dim X as integer, etc). Here is the code:

Range("B5") = "=SUM(B10:B100)"

or

X = "=SUM(B10:B100)

There are no quotation marks inside the parentheses in "=Sum(B10:B100) but there are quotation marks inside the parentheses in Range("B5"). Also there is a space between the equals sign and the quotation to the right of it.

It will not matter if some cells are empty, it will simply see them as containing zeros!

This should do it for you!

Should be :

<h2 class="col-md-4 col-md-offset-1">Browse.</h2>
<h2 class="col-md-4 col-md-offset-2">create.</h2>
<h2 class="col-md-4 col-md-offset-3">share.</h2>

This typically is caused by the mount directory being left mounted due to a crash of your filesystem. Go to the parent directory of the mount point and enter fusermount -u YOUR_MNT_DIR.

If this doesn't do the trick, do sudo umount -l YOUR_MNT_DIR.

for those like me still stuck with SQL Server 2000, SET ROWCOUNT {number}; can be used before the UPDATE query

SET ROWCOUNT 100;
UPDATE Table SET ..;
SET ROWCOUNT 0;

will limit the update to 100 rows

It has been deprecated at least since SQL 2005, but as of SQL 2017 it still works. https://docs.microsoft.com/en-us/sql/t-sql/statements/set-rowcount-transact-sql?view=sql-server-2017

Best I found on internet for this is ngx-navigation-with-data. It is very simple and good for navigation the data from one component to another component. You have to just import the component class and use it in very simple way. Suppose you have home and about component and want to send data then

HOME COMPONENT

import { Component, OnInit } from '@angular/core';
import { NgxNavigationWithDataComponent } from 'ngx-navigation-with-data';

@Component({
 selector: 'app-home',
 templateUrl: './home.component.html',
 styleUrls: ['./home.component.css']
})
export class HomeComponent implements OnInit {

constructor(public navCtrl: NgxNavigationWithDataComponent) { }

 ngOnInit() {
 }

 navigateToABout() {
  this.navCtrl.navigate('about', {name:"virendta"});
 }

}

ABOUT COMPONENT

import { Component, OnInit } from '@angular/core';
import { NgxNavigationWithDataComponent } from 'ngx-navigation-with-data';

@Component({
 selector: 'app-about',
 templateUrl: './about.component.html',
 styleUrls: ['./about.component.css']
})
export class AboutComponent implements OnInit {

 constructor(public navCtrl: NgxNavigationWithDataComponent) {
  console.log(this.navCtrl.get('name')); // it will console Virendra
  console.log(this.navCtrl.data); // it will console whole data object here
 }

 ngOnInit() {
 }

}

If anyone is interested in a sortable list with a changing index per listitem (1st, 2nd, 3th etc...:

http://jsfiddle.net/aph0c1rL/1/

$(".sortable").sortable(
{
  handle:         '.handle'
, placeholder:    'sort-placeholder'
, forcePlaceholderSize: true
, start: function( e, ui )
{
    ui.item.data( 'start-pos', ui.item.index()+1 );
}
, change: function( e, ui )
  {
      var seq
      , startPos = ui.item.data( 'start-pos' )
      , $index
      , correction
      ;

      // if startPos < placeholder pos, we go from top to bottom
      // else startPos > placeholder pos, we go from bottom to top and we need to correct the index with +1
      //
      correction = startPos <= ui.placeholder.index() ? 0 : 1;

      ui.item.parent().find( 'li.prize').each( function( idx, el )
      {
        var $this = $( el )
        , $index = $this.index()
        ;

        // correction 0 means moving top to bottom, correction 1 means bottom to top
        //
        if ( ( $index+1 >= startPos && correction === 0) || ($index+1 <= startPos && correction === 1 ) )
        {
          $index = $index + correction;
          $this.find( '.ordinal-position').text( $index + ordinalSuffix( $index ) );
        }

      });

      // handle dragged item separatelly
      seq = ui.item.parent().find( 'li.sort-placeholder').index() + correction;
      ui.item.find( '.ordinal-position' ).text( seq + ordinalSuffix( seq ) );
} );

// this function adds the correct ordinal suffix to the provide number
function ordinalSuffix( number )
{
  var suffix = '';

  if ( number / 10 % 10 === 1 )
  {
    suffix = "th";
  }
  else if ( number > 0 )
  {

    switch( number % 10 )
    {
      case 1:
        suffix = "st";
        break;
      case 2:
        suffix = "nd";
        break;
      case 3:
        suffix = "rd";
        break;
      default:
        suffix = "th";
        break;
    }
  }
  return suffix;
}

Your markup can look like this:

<ul class="sortable ">
<li >        
    <div>
        <span class="ordinal-position">1st</span>
         A header
    </div>
    <div>
        <span class="icon-button handle"><i class="fa fa-arrows"></i></span>
    </div>
    <div class="bpdy" >
        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
    </div>
</li>
 <li >        
    <div>
        <span class="ordinal-position">2nd</span>
         A header
    </div>
    <div>
        <span class="icon-button handle"><i class="fa fa-arrows"></i></span>
    </div>
    <div class="bpdy" >
        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
    </div>
</li>
etc....
</ul>

We use this stored procedure - it allows you to target specific tables, and use where clauses. You can find the text here.

For example, it lets you do this:

EXEC sp_generate_inserts 'titles'

Procedure:  sp_generate_inserts  (Build 22) 
        (Copyright © 2002 Narayana Vyas Kondreddi. All rights reserved.)

Purpose:    To generate INSERT statements from existing data. 
        These INSERTS can be executed to regenerate the data at some other location.
        This procedure is also useful to create a database setup, where in you can 
        script your data along with your table definitions.

Tested on:  SQL Server 7.0 and SQL Server 2000

NOTE:       This procedure may not work with tables with too many columns.
        Results can be unpredictable with huge text columns or SQL Server 2000's sql_variant data types
        Whenever possible, Use @include_column_list parameter to ommit column list in the INSERT statement, for better results
        IMPORTANT: This procedure is not tested with internation data (Extended characters or Unicode). If needed
        you might want to convert the datatypes of character variables in this procedure to their respective unicode counterparts
        like nchar and nvarchar


Example 1:  To generate INSERT statements for table 'titles':

        EXEC sp_generate_inserts 'titles'

Example 2:  To ommit the column list in the INSERT statement: (Column list is included by default)
        IMPORTANT: If you have too many columns, you are advised to ommit column list, as shown below,
        to avoid erroneous results

        EXEC sp_generate_inserts 'titles', @include_column_list = 0

Example 3:  To generate INSERT statements for 'titlesCopy' table from 'titles' table:

        EXEC sp_generate_inserts 'titles', 'titlesCopy'

Example 4:  To generate INSERT statements for 'titles' table for only those titles 
        which contain the word 'Computer' in them:
        NOTE: Do not complicate the FROM or WHERE clause here. It's assumed that you are good with T-SQL if you are using this parameter

        EXEC sp_generate_inserts 'titles', @from = "from titles where title like '%Computer%'"

Example 5:  To specify that you want to include TIMESTAMP column's data as well in the INSERT statement:
        (By default TIMESTAMP column's data is not scripted)

        EXEC sp_generate_inserts 'titles', @include_timestamp = 1

Example 6:  To print the debug information:

        EXEC sp_generate_inserts 'titles', @debug_mode = 1

Example 7:  If you are not the owner of the table, use @owner parameter to specify the owner name
        To use this option, you must have SELECT permissions on that table

        EXEC sp_generate_inserts Nickstable, @owner = 'Nick'

Example 8:  To generate INSERT statements for the rest of the columns excluding images
        When using this otion, DO NOT set @include_column_list parameter to 0.

        EXEC sp_generate_inserts imgtable, @ommit_images = 1

Example 9:  To generate INSERT statements excluding (ommiting) IDENTITY columns:
        (By default IDENTITY columns are included in the INSERT statement)

        EXEC sp_generate_inserts mytable, @ommit_identity = 1

Example 10:     To generate INSERT statements for the TOP 10 rows in the table:

        EXEC sp_generate_inserts mytable, @top = 10

Example 11:     To generate INSERT statements with only those columns you want:

        EXEC sp_generate_inserts titles, @cols_to_include = "'title','title_id','au_id'"

Example 12:     To generate INSERT statements by omitting certain columns:

        EXEC sp_generate_inserts titles, @cols_to_exclude = "'title','title_id','au_id'"

Example 13: To avoid checking the foreign key constraints while loading data with INSERT statements:

        EXEC sp_generate_inserts titles, @disable_constraints = 1

Example 14:     To exclude computed columns from the INSERT statement:
        EXEC sp_generate_inserts MyTable, @ommit_computed_cols = 1

The exact name of the extension depends on the repository from which you got PHP but look here. For example on CentOS:

yum install -y php56w php56w-opcache php56w-xml php56w-mcrypt php56w-gd php56w-devel php56w-mysql php56w-intl php56w-mbstring php56w-bcmath

sudo apt-get update
sudo apt-get install openjdk-7-jdk

and if you already have other JDK versions installed

sudo update-alternatives --config java

then select the Java 7 version.

Create a base class for your ViewModels with the following constructor code which will apply the DefaultValueAttributeswhen any inheriting model is created.

public abstract class BaseViewModel
{
    protected BaseViewModel()
    {
        // apply any DefaultValueAttribute settings to their properties
        var propertyInfos = this.GetType().GetProperties();
        foreach (var propertyInfo in propertyInfos)
        {
            var attributes = propertyInfo.GetCustomAttributes(typeof(DefaultValueAttribute), true);
            if (attributes.Any())
            {
                var attribute = (DefaultValueAttribute) attributes[0];
                propertyInfo.SetValue(this, attribute.Value, null);
            }
        }
    }
}

And inherit from this in your ViewModels:

public class SearchModel : BaseViewModel
{
    [DefaultValue(true)]
    public bool IsMale { get; set; }
    [DefaultValue(true)]
    public bool IsFemale { get; set; }
}

c=$(date -d "$b 10 min" "+%Y-%m-%d %H:%M:%S")
#date -d "$a 30 min" "+%Y-%m-%d %H:%M:%S"

echo Entered Date is $x
echo Second Date is $b

Unfortunately, np.polynomial.polynomial.polyfit returns the coefficients in the opposite order of that for np.polyfit and np.polyval (or, as you used np.poly1d). To illustrate:

In [40]: np.polynomial.polynomial.polyfit(x, y, 4)
Out[40]: 
array([  84.29340848, -100.53595376,   44.83281408,   -8.85931101,
          0.65459882])

In [41]: np.polyfit(x, y, 4)
Out[41]: 
array([   0.65459882,   -8.859311  ,   44.83281407, -100.53595375,
         84.29340846])

In general: np.polynomial.polynomial.polyfit returns coefficients [A, B, C] to A + Bx + Cx^2 + ..., while np.polyfit returns: ... + Ax^2 + Bx + C.

So if you want to use this combination of functions, you must reverse the order of coefficients, as in:

ffit = np.polyval(coefs[::-1], x_new)

However, the documentation states clearly to avoid np.polyfit, np.polyval, and np.poly1d, and instead to use only the new(er) package.

You're safest to use only the polynomial package:

import numpy.polynomial.polynomial as poly

coefs = poly.polyfit(x, y, 4)
ffit = poly.polyval(x_new, coefs)
plt.plot(x_new, ffit)

Or, to create the polynomial function:

ffit = poly.Polynomial(coefs)    # instead of np.poly1d
plt.plot(x_new, ffit(x_new))

On your Terminal:

• Type cd ~/ to go to your home folder.

• Type touch .bash_profile to create your new file.

• Edit .bash_profile with your code editor (or you can just type open -e .bash_profile to open it in TextEdit).
• Type . .bash_profile to reload .bash_profile and update any functions you add.

Small tip for you. Microsoft frequently has 'launch parties' or 'launch events' in which they frequently distribute licensed, not for resale copies, of that product. I've gotten the last two versions of VS (2005 and 2008) by attending my local .NET user group chapter during those days.

UPDATE:

Starting end August 2012, the API has been updated to allow you to retrieve user's profile pictures in varying sizes. Add the optional width and height fields as URL parameters:

https://graph.facebook.com/USER_ID/picture?width=WIDTH&height=HEIGHT

where WIDTH and HEIGHT are your requested dimension values.

This will return a profile picture with a minimum size of WIDTH x HEIGHT while trying to preserve the aspect ratio. For example,

https://graph.facebook.com/redbull/picture?width=140&height=110

returns

    {
      "data": {
        "url": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash4/c0.19.180.142/s148x148/2624_134501175351_4831452_a.jpg",
        "width": 148,
        "height": 117,
        "is_silhouette": false
      }
   }

END UPDATE

To get a user's profile picture, call

https://graph.facebook.com/USER_ID/picture

where USER_ID can be the user id number or the user name.

To get a user profile picture of a specific size, call

https://graph.facebook.com/USER_ID/picture?type=SIZE

where SIZE should be replaced with one of the words

square
small
normal
large

depending on the size you want.

This call will return a URL to a single image with its size based on your chosen type parameter.

For example:

https://graph.facebook.com/USER_ID/picture?type=small

returns a URL to a small version of the image.

The API only specifies the maximum size for profile images, not the actual size.

Square:

maximum width and height of 50 pixels.

Small

maximum width of 50 pixels and a maximum height of 150 pixels.

Normal

maximum width of 100 pixels and a maximum height of 300 pixels.

Large

maximum width of 200 pixels and a maximum height of 600 pixels.

If you call the default USER_ID/picture you get the square type.

CLARIFICATION

If you call (as per above example)

https://graph.facebook.com/redbull/picture?width=140&height=110

it will return a JSON response if you're using one of the Facebook SDKs request methods. Otherwise it will return the image itself. To always retrieve the JSON, add:

&redirect=false

like so:

https://graph.facebook.com/redbull/picture?width=140&height=110&redirect=false

maybe not as stylish, but easier:

#!/bin/bash
log="/var/log/yourlog"
/path/to/your/script.py 2>&1 | (while read; do echo "$REPLY" >> $log; done)

Things have changed since this question was originally asked and answered. There's been a large amount of work done on getting cross-browser font embedding for body text to work using @font-face embedding.

Paul Irish put together Bulletproof @font-face syntax combining attempts from multiple other people. If you actually go through the entire article (not just the top) it allows a single @font-face statement to cover IE, Firefox, Safari, Opera, Chrome and possibly others. Basically this can feed out OTF, EOT, SVG and WOFF in ways that don't break anything.

Snipped from his article:

@font-face {
  font-family: 'Graublau Web';
  src: url('GraublauWeb.eot');
  src: local('Graublau Web Regular'), local('Graublau Web'),
    url("GraublauWeb.woff") format("woff"),
    url("GraublauWeb.otf") format("opentype"),
    url("GraublauWeb.svg#grablau") format("svg");
}

Working from that base, Font Squirrel put together a variety of useful tools including the @font-face Generator which allows you to upload a TTF or OTF file and get auto-converted font files for the other types, along with pre-built CSS and a demo HTML page. Font Squirrel also has Hundreds of @font-face kits.

Soma Design also put together the FontFriend Bookmarklet, which redefines fonts on a page on the fly so you can try things out. It includes drag-and-drop @font-face support in FireFox 3.6+.

More recently, Google has started to provide the Google Web Fonts, an assortment of fonts available under an Open Source license and served from Google's servers.

License Restrictions

Finally, WebFonts.info has put together a nice wiki'd list of Fonts available for @font-face embedding based on licenses. It doesn't claim to be an exhaustive list, but fonts on it should be available (possibly with conditions such as an attribution in the CSS file) for embedding/linking. It's important to read the licenses, because there are some limitations that aren't pushed forward obviously on the font downloads.

If the string is fixed you can simply use:

if line.startswith("Path="):
    return line[5:]

which gives you everything from position 5 on in the string (a string is also a sequence so these sequence operators work here, too).

Or you can split the line at the first =:

if "=" in line:
    param, value = line.split("=",1)

Then param is "Path" and value is the rest after the first =.

Just attend those: 1- Gmail authentication for allow low level emails does not accept before you restart your client browser 2- If you want to send email with nodemailer and you wouldnt like to use xouath2 protocol there you should write as secureconnection:false like below

const routes = require('express').Router();
var nodemailer = require('nodemailer');
var smtpTransport = require('nodemailer-smtp-transport');



routes.get('/test', (req, res) => {
  res.status(200).json({ message: 'test!' });
});

routes.post('/Email', (req, res) =>{

    var smtpTransport = nodemailer.createTransport({
        host: "smtp.gmail.com",
        secureConnection: false,
        port: 587,
        requiresAuth: true,
        domains: ["gmail.com", "googlemail.com"],
        auth: {
            user: "your gmail account", 
            pass: "your password*"
        }
});  

  var mailOptions = {
      from: '[email protected]',
      to:'[email protected]',
      subject: req.body.subject,
      //text: req.body.content,
      html: '<p>'+req.body.content+' </p>'
  };

  smtpTransport.sendMail(mailOptions, (error, info) => {
    if (error) {
        return console.log('Error while sending mail: ' + error);
    } else {
        console.log('Message sent: %s', info.messageId);
    }
    smtpTransport.close();
});  

})

module.exports = routes;

While Andriy's proposal will work well for INSERTs of a small number of records, full table scans will be done on the final join as both 'enumerated' and '@new_super' are not indexed, resulting in poor performance for large inserts.

This can be resolved by specifying a primary key on the @new_super table, as follows:

DECLARE @new_super TABLE (
  row_num INT IDENTITY(1,1) PRIMARY KEY CLUSTERED,
  super_id   int
);

This will result in the SQL optimizer scanning through the 'enumerated' table but doing an indexed join on @new_super to get the new key.

You can do in this in Angular with ECMAScript6 by using the spread operator:

let copy = {...myObject};

This is another method I use because changing DropDownSyle to DropDownList makes it look 3D and sometimes its just plain ugly.

You can prevent user input by handling the KeyPress event of the ComboBox like this.

private void ComboBox1_KeyPress(object sender, KeyPressEventArgs e)
{
      e.Handled = true;
}

I had the same error. The first time I used the 32-bit version of python but my computer is 64-bit. I then reinstalled the 64-bit version and succeeded.

This will work for generating a number 1 - 10. Make sure you import Random at the top of your code.

import java.util.Random;

If you want to test it out try something like this.

Random rn = new Random();

for(int i =0; i < 100; i++)
{
    int answer = rn.nextInt(10) + 1;
    System.out.println(answer);
}

Also if you change the number in parenthesis it will create a random number from 0 to that number -1 (unless you add one of course like you have then it will be from 1 to the number you've entered).

Quicksort has a better average case complexity but in some applications it is the wrong choice. Quicksort is vulnerable to denial of service attacks. If an attacker can choose the input to be sorted, he can easily construct a set that takes the worst case time complexity of o(n^2).

Mergesort's average case complexity and worst case complexity are the same, and as such doesn't suffer the same problem. This property of merge-sort also makes it the superior choice for real-time systems - precisely because there aren't pathological cases that cause it to run much, much slower.

I'm a bigger fan of Mergesort than I am of Quicksort, for these reasons.

I had a red X on a folder, but not on any of the files inside it. The only thing that fixed it was clicking and dragging some of the files from the problem folder into another folder, and then performing Maven -> Update Project. I could then drag the files back without the red X returning.

First a CMP (comparison) instruction is called then one of the following:

jle - jump to line if less than or equal to
jge - jump to line if greater than or equal to

The lowest assembler works with is bytes, not bits (directly anyway). If you want to know about bit logic you'll need to take a look at circuit design.

According to the settings reference:

updatePolicy: This element specifies how often updates should attempt to occur. Maven will compare the local POM’s timestamp (stored in a repository’s maven-metadata file) to the remote. The choices are: always, daily (default), interval:X (where X is an integer in minutes) or never.

Example:

<profiles>
    <profile>
      ...
      <repositories>
        <repository>
          <id>myRepo</id>
          <name>My Repository</name>
          <releases>
            <enabled>false</enabled>
            <updatePolicy>always</updatePolicy>
            <checksumPolicy>warn</checksumPolicy>
          </releases>
         </repository>
      </repositories>
      ...
    </profile>
  </profiles>
  ...
</settings>

You can also do this without cat, though honestly cat is more readable:

>> file1 < file2

The >> appends STDIN to file1 and the < dumps file2 to STDIN.

I having some problem with the accepted answer, but it seems it solve answer for others. I would like a solution that can get a response from the url it uses, so I thought http would be great for that functionality, and for that I found this answer really helpful. How do I check Internet Connectivity using HTTP requests(Flutter/Dart)?

The performance should be identical, but I would suggest using the join-version due to improved clarity when it comes to outer joins.

Also unintentional cartesian products can be avoided using the join-version.

A third effect is an easier to read SQL with a simpler WHERE-condition.

While @Timar's answer works perfectly for null default values (what was asked for), here another easy solution which allows other default values: Define an option interface as well as an according constant containing the defaults; in the constructor use the spread operator to set the options member variable

interface IXOptions {
    a?: string,
    b?: any,
    c?: number
}

const XDefaults: IXOptions = {
    a: "default",
    b: null,
    c: 1
}

export class ClassX {
    private options: IXOptions;

    constructor(XOptions: IXOptions) {
        this.options = { ...XDefaults, ...XOptions };
    }

    public printOptions(): void {
        console.log(this.options.a);
        console.log(this.options.b);
        console.log(this.options.c);
    }
}

Now you can use the class like this:

const x = new ClassX({ a: "set" });
x.printOptions();

Output:

set
null
1

i find that this works for me

db.getCollection('collectionName').findOne({"fieldName" : {$ne: null}})

Arduino specifically provides absolutely no way to exit their loop function, as exhibited by the code that actually runs it:

setup();

for (;;) {
    loop();
    if (serialEventRun) serialEventRun();
}

Besides, on a microcontroller there isn't anything to exit to in the first place.

The closest you can do is to just halt the processor. That will stop processing until it's reset.

Basically, to make a cross domain AJAX requests, the requested server should allow the cross origin sharing of resources (CORS). You can read more about that from here: http://www.html5rocks.com/en/tutorials/cors/

In your scenario, you are setting the headers in the client which in fact needs to be set into http://localhost:8080/app server side code.

If you are using PHP Apache server, then you will need to add following in your .htaccess file:

Header set Access-Control-Allow-Origin "*"

Use the abs function:

int sum=0;
for(Integer i : container)
  sum+=Math.abs(i);

I am using MVC 1.0 RTM and none of the above solutions worked for me. But this one did:

Public Function RenderView(ByVal viewContext As ViewContext) As String

    Dim html As String = ""

    Dim response As HttpResponse = HttpContext.Current.Response

    Using tempWriter As New System.IO.StringWriter()

        Dim privateMethod As MethodInfo = response.GetType().GetMethod("SwitchWriter", BindingFlags.NonPublic Or BindingFlags.Instance)

        Dim currentWriter As Object = privateMethod.Invoke(response, BindingFlags.NonPublic Or BindingFlags.Instance Or BindingFlags.InvokeMethod, Nothing, New Object() {tempWriter}, Nothing)

        Try
            viewContext.View.Render(viewContext, Nothing)

If you want to access a resource from some other class (i.g. not a xaml codebehind), you can use

Application.Current.Resources["resourceName"];

from System.Windows namespace.

My favorite answer is as what the first sentence in this thread suggested. Use an Adjacency List to maintain the hierarchy and use Nested Sets to query the hierarchy.

The problem up until now has been that the coversion method from an Adjacecy List to Nested Sets has been frightfully slow because most people use the extreme RBAR method known as a "Push Stack" to do the conversion and has been considered to be way to expensive to reach the Nirvana of the simplicity of maintenance by the Adjacency List and the awesome performance of Nested Sets. As a result, most people end up having to settle for one or the other especially if there are more than, say, a lousy 100,000 nodes or so. Using the push stack method can take a whole day to do the conversion on what MLM'ers would consider to be a small million node hierarchy.

I thought I'd give Celko a bit of competition by coming up with a method to convert an Adjacency List to Nested sets at speeds that just seem impossible. Here's the performance of the push stack method on my i5 laptop.

Duration for     1,000 Nodes = 00:00:00:870 
Duration for    10,000 Nodes = 00:01:01:783 (70 times slower instead of just 10)
Duration for   100,000 Nodes = 00:49:59:730 (3,446 times slower instead of just 100) 
Duration for 1,000,000 Nodes = 'Didn't even try this'

And here's the duration for the new method (with the push stack method in parenthesis).

Duration for     1,000 Nodes = 00:00:00:053 (compared to 00:00:00:870)
Duration for    10,000 Nodes = 00:00:00:323 (compared to 00:01:01:783)
Duration for   100,000 Nodes = 00:00:03:867 (compared to 00:49:59:730)
Duration for 1,000,000 Nodes = 00:00:54:283 (compared to something like 2 days!!!)

Yes, that's correct. 1 million nodes converted in less than a minute and 100,000 nodes in under 4 seconds.

You can read about the new method and get a copy of the code at the following URL. http://www.sqlservercentral.com/articles/Hierarchy/94040/

I also developed a "pre-aggregated" hierarchy using similar methods. MLM'ers and people making bills of materials will be particularly interested in this article. http://www.sqlservercentral.com/articles/T-SQL/94570/

If you do stop by to take a look at either article, jump into the "Join the discussion" link and let me know what you think.

Following should do it :

#include <stdio.h>
#include <string.h>

int main (int argc, char const* argv[])
{
    char word[] = "abcde";
    int i;
    int len = strlen(word);
    int rem = 1;

    /* remove rem'th char from word */
    for (i = rem; i < len - 1; i++) word[i] = word[i + 1];
    if (i < len) word[i] = '\0';

    printf("%s\n", word);
    return 0;
}

With Java9, one can make use of the iterate(int seed, IntPredicate hasNext,IntUnaryOperator next) as follows:-

List<Integer> indexes = IntStream
          .iterate(word.indexOf(c), index -> index >= 0, index -> word.indexOf(c, index + 1))
          .boxed()
          .collect(Collectors.toList());
System.out.printlnt(indexes);

To my mind the case for a PT (as @Nathan Fisher) is a 'no brainer', but I would add a column to facilitate ordering by rank (up or down):

OPS is entered as VALUES (Sum of) twice so I have renamed the column labels to make clearer which is which. The PT is in a different sheet from the data but could be in the same sheet.

Rank is set with a right click on a data point selected in that column and Show Values As... and Rank Largest to Smallest (there are other options) with the Base field as Player and the filter is a Value Filters, Top 10... one:

Once in a PT the power of that feature can very easily be applied to view the data in many other ways, with no change of formula (there isn't one!).

In the case of a tie for the last position included in the filter both results are included (Top 5 would show six or more results). A tie for top rank between just two players would show as 1 1 3 4 5 for Top 5.

In Django, MVC structure is as Chris Pratt said, different from classical MVC model used in other frameworks, I think the main reason for doing this is avoiding a too strict application structure, like happens in others MVC frameworks like CakePHP.

In Django, MVC was implemented in the following way:

View layer is splitted in two. The views should be used only to manage HTTP requests, they are called and respond to them. Views communicate with the rest of your application (forms, modelforms, custom classes, of in simple cases directly with models). To create the interface we use Templates. Templates are string-like to Django, it maps a context into them, and this context was communicated to the view by the application (when view asks).

Model layer gives encapsulation, abstraction, validation, intelligence and makes your data object-oriented (they say someday DBMS will also). This doesn't means that you should make huge models.py files (in fact a very good advice is to split your models in different files, put them into a folder called 'models', make an '__init__.py' file into this folder where you import all your models and finally use the attribute 'app_label' of models.Model class). Model should abstract you from operating with data, it will make your application simpler. You should also, if required, create external classes, like "tools" for your models.You can also use heritage in models, setting the 'abstract' attribute of your model's Meta class to 'True'.

Where is the rest? Well, small web applications generally are a sort of an interface to data, in some small program cases using views to query or insert data would be enough. More common cases will use Forms or ModelForms, which are actually "controllers". This is not other than a practical solution to a common problem, and a very fast one. It's what a website use to do.

If Forms are not enogh for you, then you should create your own classes to do the magic, a very good example of this is admin application: you can read ModelAmin code, this actually works as a controller. There is not a standard structure, I suggest you to examine existing Django apps, it depends on each case. This is what Django developers intended, you can add xml parser class, an API connector class, add Celery for performing tasks, twisted for a reactor-based application, use only the ORM, make a web service, modify the admin application and more... It's your responsability to make good quality code, respect MVC philosophy or not, make it module based and creating your own abstraction layers. It's very flexible.

My advice: read as much code as you can, there are lots of django applications around, but don't take them so seriously. Each case is different, patterns and theory helps, but not always, this is an imprecise cience, django just provide you good tools that you can use to aliviate some pains (like admin interface, web form validation, i18n, observer pattern implementation, all the previously mentioned and others), but good designs come from experienced designers.

PS.: use 'User' class from auth application (from standard django), you can make for example user profiles, or at least read its code, it will be useful for your case.

The new testing improvements that debuted in Spring Boot 1.4.M2 can help reduce the amount of code you need to write situation such as these.

The test would look like so:

import static org.springframework.test.web.servlet.request.MockMvcRequestB??uilders.get; 
import static org.springframework.test.web.servlet.result.MockMvcResultMat??chers.content; 
import static org.springframework.test.web.servlet.result.MockMvcResultMat??chers.status;

    @RunWith(SpringRunner.class)
    @WebMvcTest(HelloWorld.class)
    public class UserVehicleControllerTests {

        @Autowired
        private MockMvc mockMvc;

        @Test
        public void testSayHelloWorld() throws Exception {
            this.mockMvc.perform(get("/").accept(MediaType.parseMediaType("application/json;charset=UTF-8")))
                    .andExpect(status().isOk())
                    .andExpect(content().contentType("application/json"));

        }

    }

2. centerHorizontal

3. centerVertical

private void addOrRemoveProperty(View view, int property, boolean flag){
    RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) view.getLayoutParams();
    if(flag){
        layoutParams.addRule(property);
    }else {
        layoutParams.removeRule(property);
    }
    view.setLayoutParams(layoutParams);
}

How to call method:

centerInParent - true

addOrRemoveProperty(mView, RelativeLayout.CENTER_IN_PARENT, true);

centerInParent - false

addOrRemoveProperty(mView, RelativeLayout.CENTER_IN_PARENT, false);

centerHorizontal - true

addOrRemoveProperty(mView, RelativeLayout.CENTER_HORIZONTAL, true);

centerHorizontal - false

addOrRemoveProperty(mView, RelativeLayout.CENTER_HORIZONTAL, false);

centerVertical - true

addOrRemoveProperty(mView, RelativeLayout.CENTER_VERTICAL, true);

centerVertical - false

addOrRemoveProperty(mView, RelativeLayout.CENTER_VERTICAL, false);

Hope this would help you.

Note: I have verified this in the latest version of IE, and other browsers like Mozilla and Chrome and this works for me. Hope it works for others as well.

This isn't the most efficient approach but it will give your answer and I'm unclear if your window is 5 points or 10. If its 10, replace each 5 with 10 and the 4 with 9.

There is nothing bad or better, It just depends on the precedence of operators. Since || has higher precedence than or, so || is mostly used.

reloadData is no good because there's no animation...

This is what I'm currently trying:

NSArray* paths = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:0 inSection:0]];
[self.tableView beginUpdates];
[self.tableView insertRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationFade];
[self.tableView deleteRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationFade];
[self.tableView endUpdates];

It almost works right. Almost. I'm increasing the height of the cell, and sometimes there's a little "hiccup" in the table view as the cell is replaced, as if some scrolling position in the table view is being preserved, the new cell (which is the first cell in the table) ends up with its offset too high, and the scrollview bounces to reposition it.

I could not find any solution that would fix my issue. All simulators were there for all projects but the one that I needed them.

Assuming you are using a Date range Picker to retrieve the dates. You could do something like to to get what you want.

$('#daterange-btn').daterangepicker({
            ranges: {
                'Today': [moment(), moment()],
                'Yesterday': [moment().subtract(1, 'days'), moment().subtract(1, 'days')],
                'Last 7 Days': [moment().subtract(6, 'days'), moment()],
                'Last 30 Days': [moment().subtract(29, 'days'), moment()],
                'This Month': [moment().startOf('month'), moment().endOf('month')],
                'Last Month': [moment().subtract(1, 'month').startOf('month'), moment().subtract(1, 'month').endOf('month')]
            },
            startDate: moment().subtract(29, 'days'),
            endDate: moment()
        }, function (start, end) {
      alert( 'Date is between' + start.format('YYYY-MM-DD h:m') + 'and' + end.format('YYYY-MM-DD h:m')}

In python, integers and strings are immutable and are passed by value. You cannot pass a string, or integer, to a function and expect the argument to be modified.

So to convert string limit="100" to a number, you need to do

limit = int(limit) # will return new object (integer) and assign to "limit"

If you really want to go around it, you can use a list. Lists are mutable in python; when you pass a list, you pass it's reference, not copy. So you could do:

def int_in_place(mutable):
    mutable[0] = int(mutable[0])

mutable = ["1000"]
int_in_place(mutable)
# now mutable is a list with a single integer

But you should not need it really. (maybe sometimes when you work with recursions and need to pass some mutable state).

Implement the Comparable interface on your customObject.

What helped me was to register the source directory for jni files in the build.gradle file. Add this to your gradle file:

android {
    sourceSets {
        main {
            jniLibs.srcDir '[YOUR_JNI_DIR]' // i.e. 'libs'
        }
    }
}

This is what I ended up doing. Hopefully someone might find it useful.

@Transactional
public void deleteGroup(Long groupId) {
    Group group = groupRepository.findById(groupId).orElseThrow();
    group.getUsers().forEach(u -> u.getGroups().remove(group));
    userRepository.saveAll(group.getUsers());
    groupRepository.delete(group);
}

Daniel Hilgarth's answer above leads to a System.NotSupported exception With Entity-Framework. With Entity-Framework, it has to be:

I modified my activate script to source the file .virtualenvrc, if it exists in the current directory, and to save/restore PYTHONPATH on activate/deactivate.

You can find the patched activate script here.. It's a drop-in replacement for the activate script created by virtualenv 1.11.6.

Then I added something like this to my .virtualenvrc:

export PYTHONPATH="${PYTHONPATH:+$PYTHONPATH:}/some/library/path"

<asp:Label ID="ServiceBeginDate" runat="server" Text='<%# (DataBinder.Eval(Container.DataItem, "ServiceBeginDate", "{0:yyyy}") == "0001") ? "" : DataBinder.Eval(Container.DataItem, "ServiceBeginDate", "{0:MM/dd/yyyy}") %>'>
</asp:Label>

Changed my application.conf file as below. It solved the problem.

Before Change:

slick {
  dbs {
    default {
      profile = "slick.jdbc.MySQLProfile$"
      db {
        driver = "com.mysql.jdbc.Driver"
        url = "jdbc:mysql://localhost:3306/test"
        user = "root"
        password = "root"
      }
    }
  }
}

After Change:

slick {
  dbs {
    default {
      profile = "slick.jdbc.MySQLProfile$"
      db {
        driver = "com.mysql.cj.jdbc.Driver"
        url = "jdbc:mysql://localhost:3306/test"
        user = "root"
        password = "root"
      }
    }
  }
}

This turned out to be very flexible and extensible. $field =~ s/[^\x00-\x7F]//g ; # thus all non ASCII or specific items in question could be cleaned. Very nice either in selection or pre-processing of items that will eventually become hash keys.

First, you know that "blank" and "null" are two COMPLETELY DIFFERENT THINGS? Correct?

Second: in most programming languages, "" means an "empty string". A zero-length string. No characters in it.

SQL doesn't necessarily work like that. If I define a column "name char(5)", then a "blank" name will be " " (5 spaces).

It sounds like you might want something like this:

select count(*) from my_table where Length(trim(my_column)) = 0;

"Trim()" is one of many Oracle functions you can use in PL/SQL. It's documented here:

http://www.techonthenet.com/oracle/functions/trim.php

'Hope that helps!

simple

(i == null) ? i.Value : 0;

Alternatively, in python 3.6+, you can generate Unicode superscript and copy paste that in your code:

ax1.set_ylabel('Rate (min?¹)')

This message can also occur when you specify the incorrect decryption password (yeah, lame, but not quite obvious to realize this from the error message, huh?).

I was using the command line to decrypt the recent DataBase backup for my auxiliary tool and suddenly faced this issue.

Finally, after 10 mins of grief and plus reading through this question/answers I have remembered that the password is different and everything worked just fine with the correct password.

Can use getElementsByTagName

var x = document.getElementsByTagName("title")[0];

alert(x.innerHTML)

// or

alert(x.textContent)

// or

document.querySelector('title')

Edits as suggested by Paul

I started to get the issue today only on chrome and not safari for the same project/url for my goormide container (node.js)

After trying several suggestions above which didn't appear to work and backtracking on some code changes I made from yesterday to today which also made no difference I ended up in the chrome settings clicking:

1.Settings;

2.scroll down to bottom, select: "Advanced";

3.scroll down to bottom, select: "Restore settings to their original defaults";

That appears to have fixed the problem as I no longer get the warning/error in the console and the page displays as it should. Reading the posts above it appears the issue can occur from any number of sources so the settings reset is a potential generic fix. Cheers

The common approach is to use the default value as a label, and then remove it when the field gains the focus.

I really dislike this approach as it has accessibility and usability implications.

Instead, I would start by using a standard element next to the field.

Then, if JavaScript is active, set a class on an ancestor element which causes some new styles to apply that:

• Relatively position a div that contains the input and label
• Absolutely position the label
• Absolutely position the input on top of the label
• Remove the borders of the input and set its background-color to transparent

Then, and also whenever the input loses the focus, I test to see if the input has a value. If it does, ensure that an ancestor element has a class (e.g. "hide-label"), otherwise ensure that it does not have that class.

Whenever the input gains the focus, set that class.

The stylesheet would use that classname in a selector to hide the label (using text-indent: -9999px; usually).

This approach provides a decent experience for all users, including those with JS disabled and those using screen readers.

i made a column by name : update-at in phpMyAdmin and got the current time from Date() method in my code (nodejs) . with every change in table this column hold the time of changes.

If you want to insert all the columns then

insert into def select * from abc;

here the number of columns in def should be equal to abc.

if you want to insert the subsets of columns then

insert into def (col1,col2, col3 ) select scol1,scol2,scol3 from abc; 

if you want to insert some hardcorded values then

insert into def (col1, col2,col3) select 'hardcoded value',scol2, scol3 from abc;

This stuff comes from ES file explorer

Just go into this app > settings

Then there is an option that says logging floating window, you just need to disable that and you will get rid of this infernal bubble for good

Declare in your Model with

  [DataType(DataType.MultilineText)]
  public string urString { get; set; }

Then in .cshtml can make use of editor as below. you can make use of @cols and @rows for TextArea size

     @Html.EditorFor(model => model.urString, new { htmlAttributes = new { @class = "",@cols = 35, @rows = 3 } })

Thanks !

Having a hidden input field leads to problems with datepicker dialog positioning (dialog is horizontally centered). You could alter the dialog's margin, but there's a better way.

Just create an input field and "hide" it by setting it's opacity to 0 and making it 1px wide. Also position it near (or under) the button, or where ever you want the datepicker to appear.

Then attach the datepicker to the "hidden" input field and show it when user presses the button.

HTML:

<button id="date-button">Show Calendar</button>
<input type="text" name="date-field" id="date-field" value="">

CSS:

#date-button {
    position: absolute;
    top: 0;
    left: 0;
    z-index: 2;
    height 30px;
}

#date-field {
    position: absolute;
    top: 0;
    left: 0;
    z-index: 1;
    width: 1px;
    height: 32px; // height of the button + a little margin
    opacity: 0;
}

JS:

$(function() {
   $('#date-field').datepicker();

   $('#date-button').on('click', function() {
      $('#date-field').datepicker('show');
   });
});

Note: not tested with all browsers.

Most of the solutions above only give the full match as a result ignoring the capture groups e.g.: ^\d+\s+(\d+)

To get the capture group matches as expected you need something like (Swift4) :

public extension String {
    public func capturedGroups(withRegex pattern: String) -> [String] {
        var results = [String]()

        var regex: NSRegularExpression
        do {
            regex = try NSRegularExpression(pattern: pattern, options: [])
        } catch {
            return results
        }
        let matches = regex.matches(in: self, options: [], range: NSRange(location:0, length: self.count))

        guard let match = matches.first else { return results }

        let lastRangeIndex = match.numberOfRanges - 1
        guard lastRangeIndex >= 1 else { return results }

        for i in 1...lastRangeIndex {
            let capturedGroupIndex = match.range(at: i)
            let matchedString = (self as NSString).substring(with: capturedGroupIndex)
            results.append(matchedString)
        }

        return results
    }
}

Go to your Microsoft SDKs directory. A path like this:

C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6 Tools

Open the WCF Configuration Editor (Microsoft Service Configuration Editor) from that directory:

SvcConfigEditor.exe

(another option to open this tool is by navigating in Visual Studio 2017 to "Tools" > "WCF Service Configuration Editor")

Open your .config file or create a new one using the editor and navigate to Diagnostics.

There you can click the "Enable MessageLogging".

A Json Web Token made up of three parts. The header, the payload and the signature Now the header is just some metadata about the token itself and the payload is the data that we can encode into the token, any data really that we want. So the more data we want to encode here the bigger the JWT. Anyway, these two parts are just plain text that will get encoded, but not encrypted.

So anyone will be able to decode them and to read them, we cannot store any sensitive data in here. But that's not a problem at all because in the third part, so in the signature, is where things really get interesting. The signature is created using the header, the payload, and the secret that is saved on the server.

And this whole process is then called signing the Json Web Token. The signing algorithm takes the header, the payload, and the secret to create a unique signature. So only this data plus the secret can create this signature, all right? Then together with the header and the payload, these signature forms the JWT, which then gets sent to the client.

Once the server receives a JWT to grant access to a protected route, it needs to verify it in order to determine if the user really is who he claims to be. In other words, it will verify if no one changed the header and the payload data of the token. So again, this verification step will check if no third party actually altered either the header or the payload of the Json Web Token.

So, how does this verification actually work? Well, it is actually quite straightforward. Once the JWT is received, the verification will take its header and payload, and together with the secret that is still saved on the server, basically create a test signature.

But the original signature that was generated when the JWT was first created is still in the token, right? And that's the key to this verification. Because now all we have to do is to compare the test signature with the original signature. And if the test signature is the same as the original signature, then it means that the payload and the header have not been modified.

Because if they had been modified, then the test signature would have to be different. Therefore in this case where there has been no alteration of the data, we can then authenticate the user. And of course, if the two signatures are actually different, well, then it means that someone tampered with the data. Usually by trying to change the payload. But that third party manipulating the payload does of course not have access to the secret, so they cannot sign the JWT. So the original signature will never correspond to the manipulated data. And therefore, the verification will always fail in this case. And that's the key to making this whole system work. It's the magic that makes JWT so simple, but also extremely powerful.

Now let's do some practices with nodejs:

Configuration file is perfect for storing JWT SECRET data. Using the standard HSA 256 encryption for the signature, the secret should at least be 32 characters long, but the longer the better.

config.env:

JWT_SECRET = my-32-character-ultra-secure-and-ultra-long-secret
//after 90days JWT will no longer be valid, even the signuter is correct and everything is matched.
JWT_EXPIRES_IN=90

now install JWT using command

npm i jsonwebtoken

Example after user signup passing him JWT token so he can stay logged in and get access of resources.

exports.signup = catchAsync(async (req, res, next) => {
  const newUser = await User.create({
    name: req.body.name,
    email: req.body.email,
    password: req.body.password,
    passwordConfirm: req.body.passwordConfirm,
  });
  const token = jwt.sign({ id: newUser._id }, process.env.JWT_SECRET, {
    expiresIn: process.env.JWT_EXPIRES_IN,
  });

  res.status(201).json({

In my opinion, do not take help from a third-party to generate your super-secret key, because you can't say it's secret anymore. Just use your keyboard.

Note that doing so will be unreliable in release code, due to optimization. Additionally, running the application in sandbox mode (network share) won't allow you to grab the stack frame at all.

Consider aspect-oriented programming (AOP), like PostSharp, which instead of being called from your code, modifies your code, and thus knows where it is at all times.

Let me explain clearly.. If you are familiar With rdbms.. Index is database.. And index type is table.. It mean index is collection of index types., like collection of tables as database (DB).

in NOSQL.. Index is database and index type is collections. Group of collection as database..

To execute those queries... U need to install CURL for Windows.

Curl is nothing but a command line rest tool.. If you want a graphical tool.. Try

Sense plugin for chrome...

Hope it helps..

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

Another option with pure CSS would be something like this:

nav {
    margin: 0px auto;
    width: 100%;
    height: 50px;
    background-color: white;
    float: left;
    padding: 10px;
    border: 2px solid red;
    position: relative;
    z-index: 10;
}

nav:after {
    background-color: grey;
    content: '';
    display: block;
    position: absolute;
    top: 10px;
    left: 10px;
    right: 10px;
    bottom: 10px;
    z-index: -1;
}

That is because Low is a string.

.toFixed() only works with a number.

Try doing:

Low = parseFloat(Low).toFixed(..);

Convert without creating String object:

import java.nio.CharBuffer;
import java.nio.ByteBuffer;
import java.util.Arrays;

byte[] toBytes(char[] chars) {
  CharBuffer charBuffer = CharBuffer.wrap(chars);
  ByteBuffer byteBuffer = Charset.forName("UTF-8").encode(charBuffer);
  byte[] bytes = Arrays.copyOfRange(byteBuffer.array(),
            byteBuffer.position(), byteBuffer.limit());
  Arrays.fill(byteBuffer.array(), (byte) 0); // clear sensitive data
  return bytes;
}

Usage:

char[] chars = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};
byte[] bytes = toBytes(chars);
/* do something with chars/bytes */
Arrays.fill(chars, '\u0000'); // clear sensitive data
Arrays.fill(bytes, (byte) 0); // clear sensitive data

Solution is inspired from Swing recommendation to store passwords in char[]. (See Why is char[] preferred over String for passwords?)

Remember not to write sensitive data to logs and ensure that JVM won't hold any references to it.

The code above is correct but not effective. If you don't need performance but want security you can use it. If security also not a goal then do simply String.getBytes. Code above is not effective if you look down of implementation of encode in JDK. Besides you need to copy arrays and create buffers. Another way to convert is inline all code behind encode (example for UTF-8):

val xs: Array[Char] = "A ß € ?  ".toArray
val len = xs.length
val ys: Array[Byte] = new Array(3 * len) // worst case
var i = 0; var j = 0 // i for chars; j for bytes
while (i < len) { // fill ys with bytes
  val c = xs(i)
  if (c < 0x80) {
    ys(j) = c.toByte
    i = i + 1
    j = j + 1
  } else if (c < 0x800) {
    ys(j) = (0xc0 | (c >> 6)).toByte
    ys(j + 1) = (0x80 | (c & 0x3f)).toByte
    i = i + 1
    j = j + 2
  } else if (Character.isHighSurrogate(c)) {
    if (len - i < 2) throw new Exception("overflow")
    val d = xs(i + 1)
    val uc: Int = 
      if (Character.isLowSurrogate(d)) {
        Character.toCodePoint(c, d)
      } else {
        throw new Exception("malformed")
      }
    ys(j) = (0xf0 | ((uc >> 18))).toByte
    ys(j + 1) = (0x80 | ((uc >> 12) & 0x3f)).toByte
    ys(j + 2) = (0x80 | ((uc >>  6) & 0x3f)).toByte
    ys(j + 3) = (0x80 | (uc & 0x3f)).toByte
    i = i + 2 // 2 chars
    j = j + 4
  } else if (Character.isLowSurrogate(c)) {
    throw new Exception("malformed")
  } else {
    ys(j) = (0xe0 | (c >> 12)).toByte
    ys(j + 1) = (0x80 | ((c >> 6) & 0x3f)).toByte
    ys(j + 2) = (0x80 | (c & 0x3f)).toByte
    i = i + 1
    j = j + 3
  }
}
// check
println(new String(ys, 0, j, "UTF-8"))

Excuse me for using Scala language. If you have problems with converting this code to Java I can rewrite it. What about performance always check on real data (with JMH for example). This code looks very similar to what you can see in JDK[2] and Protobuf[3].

In Swift:

For example, name of your custom class is InfoView

At first, you create files InfoView.xib and InfoView.swiftlike this:

import Foundation
import UIKit

class InfoView: UIView {
    class func instanceFromNib() -> UIView {
    return UINib(nibName: "InfoView", bundle: nil).instantiateWithOwner(nil, options: nil)[0] as! UIView
}

Then set File's Owner to UIViewController like this:

Rename your View to InfoView:

Right-click to File's Owner and connect your view field with your InfoView:

Make sure that class name is InfoView:

And after this you can add the action to button in your custom class without any problem:

And usage of this custom class in your MainViewController:

func someMethod() {
    var v = InfoView.instanceFromNib()
    v.frame = self.view.bounds
    self.view.addSubview(v)
}

It maybe is not the best way to do it. But the only I found to get the Absolute path is to calculate how many times the syntax .. was in the string and then use the function gotoparent as many times that syntax comes in the hyperlink adress. (in my case, my field is a hyperlink address. Ps: This code requires the reference to microsoft scripting runtime

Function AbsolutePath(strRelativePath As String, strCurrentFileName As String) As String
Dim fso As Object
Dim strCurrentProjectpath As String
Dim strGoToParentFolder As String
Dim strOrigineFolder As String
Dim strPath As String
Dim lngParentFolder As Long


''Pour retrouver le répertoire parent
Set fso = CreateObject("Scripting.FileSystemObject")

'' détermine le répertire du projet actif
strCurrentProjectpath = CurrentProject.Path

'' détermine le nom du répertoire dans lequel le fichier d'origine se trouve
strOrigineFolder = Replace(Replace(Replace(strRelativePath, strCurrentFileName, ""), "..", ""), "\", "")

''Extraction du chemin relatif (ex. ..\..\..)
strGoToParentFolder = Replace(Replace(strRelativePath, strOrigineFolder, ""), strCurrentFileName, "")

''retourne le nombre de fois qu'il faut remonter au répertoire parent
lngParentsFolder = Len(Replace(strGoToParentFolder, "\", "")) / 2

''détermine la valeur d'origine du répertoire du début
strPath = strCurrentProjectpath

Vérifie s 'il faut aller au répertoire parent
If lngParentsFolder < 1 Then
    'si non, alors répertoire parent et répertoire d'origine du fichier
    strPath = strCurrentProjectpath & "\" & strOrigineFolder
Else
    ''si oui, nous faisons la boucle pour retourner au répertoire d'origine
    For i = 1 To lngParentsFolder
        strPath = fso.GetParentFolderName(strPath)
    Next i
End If

''retournons le répertoire parent du fichier et son répertoire d'origine [le OUTPUT]
AbsolutePath = strPath & strOrigineFolder & "\"

End Function

According to Django documentation, inline formsets are for this purpose: "Inline formsets is a small abstraction layer on top of model formsets. These simplify the case of working with related objects via a foreign key".

See https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#inline-formsets

Based on your desire that 1317427200 be the output, there are several layers of issue to address.

• First as others have mentioned, java already uses a UTC 1/1/1970 epoch. There is normally no need to calculate the epoch and perform subtraction unless you have weird locale rules.

• Second, when you create a new Calendar it's initialized to 'now' so it includes the time of day. Changing the year/month/day doesn't affect the time of day fields. So if you want it to represent midnight of the date, you need to zero out the calendar before you set the date.

• Third, you haven't specified how you're supposed to handle time zones. Daylight Savings can cause differences in the absolute number of seconds represented by a particular calendar-on-the-wall-date, depending on where your JVM is running. Since epoch is in UTC, we probably want to work in UTC times? You may need to seek clarification from the makers of the system you're interfacing with.

• Fourth, months in Java are zero indexed. January is 0, October is 9.

Putting all that together

Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
calendar.clear();
calendar.set(2011, Calendar.OCTOBER, 1);
long secondsSinceEpoch = calendar.getTimeInMillis() / 1000L;

that will give you 1317427200

Spring MVC and Spring Boot are exist for the different purpose. So, it is not wise to compare each other as the contenders.

What is Spring Boot?

Spring Boot is a framework for packaging the spring application with sensible defaults. What does this mean?. You are developing a web application using Spring MVC, Spring Data, Hibernate and Tomcat. How do you package and deploy this application to your web server. As of now, we have to manually write the configurations, XML files, etc. for deploying to web server.

Spring Boot does that for you with Zero XML configuration in your project. Believe me, you don't need deployment descriptor, web server, etc. Spring Boot is magical framework that bundles all the dependencies for you. Finally your web application will be a standalone JAR file with embeded servers.

If you are still confused how this works, please read about microservice framework development using spring boot.

What is Spring MVC?

It is a traditional web application framework that helps you to build web applications. It is similar to Struts framework.

A Spring MVC is a Java framework which is used to build web applications. It follows the Model-View-Controller design pattern. It implements all the basic features of a core spring framework like Inversion of Control, Dependency Injection.

A Spring MVC provides an elegant solution to use MVC in spring framework by the help of DispatcherServlet. Here, DispatcherServlet is a class that receives the incoming request and maps it to the right resource such as controllers, models, and views.

I hope this helps you to understand the difference.

For Dot Net Core 3, Microsoft.Data.SqlClient should be used.

Another option is to get the stream to a byte[] and use File.WriteAllBytes. This should do:

using (var stream = new MemoryStream())
{
    input.CopyTo(stream);
    File.WriteAllBytes(file, stream.ToArray());
}

Wrapping it in an extension method gives it better naming:

public void WriteTo(this Stream input, string file)
{
    //your fav write method:

    using (var stream = File.Create(file))
    {
        input.CopyTo(stream);
    }

    //or

    using (var stream = new MemoryStream())
    {
        input.CopyTo(stream);
        File.WriteAllBytes(file, stream.ToArray());
    }

    //whatever that fits.
}

function get_mime($file) {
  if (function_exists("finfo_file")) {
    $finfo = finfo_open(FILEINFO_MIME_TYPE); // return mime type ala mimetype extension
    $mime = finfo_file($finfo, $file);
    finfo_close($finfo);
    return $mime;
  } else if (function_exists("mime_content_type")) {
    return mime_content_type($file);
  } else if (!stristr(ini_get("disable_functions"), "shell_exec")) {
    // http://stackoverflow.com/a/134930/1593459
    $file = escapeshellarg($file);
    $mime = shell_exec("file -bi " . $file);
    return $mime;
  } else {
    return false;
  }
}

For me, nothing of this does work - mime_content_type is deprecated, finfo is not installed, and shell_exec is not allowed.

Like it has been already mentioned, you are reading the file in binary mode and then creating a list of bytes. In your following for loop you are comparing string to bytes and that is where the code is failing.

Decoding the bytes while adding to the list should work. The changed code should look as follows:

with open(fname, 'rb') as f:
    lines = [x.decode('utf8').strip() for x in f.readlines()]

The bytes type was introduced in Python 3 and that is why your code worked in Python 2. In Python 2 there was no data type for bytes:

>>> s=bytes('hello')
>>> type(s)
<type 'str'>

But can I abort a Task (in .Net 4.0) in the same way not by cancellation mechanism. I want to kill the Task immediately.

Other answerers have told you not to do it. But yes, you can do it. You can supply Thread.Abort() as the delegate to be called by the Task's cancellation mechanism. Here is how you could configure this:

class HardAborter
{
  public bool WasAborted { get; private set; }
  private CancellationTokenSource Canceller { get; set; }
  private Task<object> Worker { get; set; }

  public void Start(Func<object> DoFunc)
  {
    WasAborted = false;

    // start a task with a means to do a hard abort (unsafe!)
    Canceller = new CancellationTokenSource();

    Worker = Task.Factory.StartNew(() => 
      {
        try
        {
          // specify this thread's Abort() as the cancel delegate
          using (Canceller.Token.Register(Thread.CurrentThread.Abort))
          {
            return DoFunc();
          }
        }
        catch (ThreadAbortException)
        {
          WasAborted = true;
          return false;
        }
      }, Canceller.Token);
  }

  public void Abort()
  {
    Canceller.Cancel();
  }

}

disclaimer: don't do this.

Here is an example of what not to do:

 var doNotDoThis = new HardAborter();

 // start a thread writing to the console
 doNotDoThis.Start(() =>
    {
       while (true)
       {
          Thread.Sleep(100);
          Console.Write(".");
       }
       return null;
    });


 // wait a second to see some output and show the WasAborted value as false
 Thread.Sleep(1000);
 Console.WriteLine("WasAborted: " + doNotDoThis.WasAborted);

 // wait another second, abort, and print the time
 Thread.Sleep(1000);
 doNotDoThis.Abort();
 Console.WriteLine("Abort triggered at " + DateTime.Now);

 // wait until the abort finishes and print the time
 while (!doNotDoThis.WasAborted) { Thread.CurrentThread.Join(0); }
 Console.WriteLine("WasAborted: " + doNotDoThis.WasAborted + " at " + DateTime.Now);

 Console.ReadKey();

To find the AWS_SECRET_ACCESS_KEY Its better to create new create "IAM" user Here is the steps https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users_create.html 1. Sign in to the AWS Management Console and open the IAM console at https://console.aws.amazon.com/iam/.

2. In the navigation pane, choose Users and then choose Add user.

If you insist on using the [DisplayFormat], but you are not using MVC4, you can use this:

@Html.TextBoxFor(m => m.EndDate, new { Value = @Html.DisplayFor(m=>m.EndDate), @class="datepicker" })

@CMW's answer is bang on the money. I've added this answer as an example of how to configure an initializer so that both Date and Time objects get the formatting

config/initializers/time_formats.rb

date_formats = {
  concise: '%d-%b-%Y' # 13-Jan-2014
}

Time::DATE_FORMATS.merge! date_formats
Date::DATE_FORMATS.merge! date_formats

Also the following two commands will iterate through all the DATE_FORMATS in your current environment, and display today's date and time in each format:

Date::DATE_FORMATS.keys.each{|k| puts [k,Date.today.to_s(k)].join(':- ')}
Time::DATE_FORMATS.keys.each{|k| puts [k,Time.now.to_s(k)].join(':- ')}

From http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

H2 Web Console (H2ConsoleProperties):

spring.h2.console.enabled=true //Enable the console.
spring.h2.console.path=/h2-console //Path at which the console will be available.

Adding the above two lines to my application.properties file was enough to access the H2 database web console, using the default username (sa) and password (empty, as in don't enter a password when the ui prompts you).

Just going to add a simple example to what everyone has explained,

json.load()

json.load can deserialize a file itself i.e. it accepts a file object, for example,

# open a json file for reading and print content using json.load
with open("/xyz/json_data.json", "r") as content:
  print(json.load(content))

will output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I use json.loads to open a file instead,

# you cannot use json.loads on file object
with open("json_data.json", "r") as content:
  print(json.loads(content))

I would get this error:

TypeError: expected string or buffer

json.loads()

json.loads() deserialize string.

So in order to use json.loads I will have to pass the content of the file using read() function, for example,

using content.read() with json.loads() return content of the file,

with open("json_data.json", "r") as content:
  print(json.loads(content.read()))

Output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

That's because type of content.read() is string, i.e. <type 'str'>

If I use json.load() with content.read(), I will get error,

with open("json_data.json", "r") as content:
  print(json.load(content.read()))

Gives,

AttributeError: 'str' object has no attribute 'read'

So, now you know json.load deserialze file and json.loads deserialize a string.

Another example,

sys.stdin return file object, so if i do print(json.load(sys.stdin)), I will get actual json data,

cat json_data.json | ./test.py

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I want to use json.loads(), I would do print(json.loads(sys.stdin.read())) instead.

The ternary operator can only be the right side of an assignment and not a statement of its own.

http://www.devdaily.com/java/edu/pj/pj010018/

For 'out', the following seems to work for me.

public interface IService
{
    void DoSomething(out string a);
}

[TestMethod]
public void Test()
{
    var service = new Mock<IService>();
    var expectedValue = "value";
    service.Setup(s => s.DoSomething(out expectedValue));

    string actualValue;
    service.Object.DoSomething(out actualValue);
    Assert.AreEqual(expectedValue, actualValue);
}

I'm guessing that Moq looks at the value of 'expectedValue' when you call Setup and remembers it.

For ref, I'm looking for an answer also.

I found the following QuickStart guide useful: https://github.com/Moq/moq4/wiki/Quickstart

Following worked for me in C++11:

template <typename Enum>
constexpr typename std::enable_if<std::is_enum<Enum>::value,
                                  typename std::underlying_type<Enum>::type>::type
to_integral(Enum const& value) {
    return static_cast<typename std::underlying_type<Enum>::type>(value);
}

by using jquery to register .mousemove to document to change the image .css left and top to event.pageX and event.pageY.

example as below http://jsfiddle.net/BfLAh/1/

$(document).mousemove(function(e) {
  $("#follow").css({
    left: e.pageX,
    top: e.pageY
  });
});

#follow {
  position: absolute;
  text-align: center;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="follow"><img src="https://placekitten.com/96/140" /><br>Kitteh</br>
</div>

updated to follow slowly

http://jsfiddle.net/BfLAh/3/

for the orientation , you need to get the current css left and css top and compare with event.pageX and event.pageY , then set the image orientation with

-webkit-transform: rotate(-90deg); 
-moz-transform: rotate(-90deg); 

for the speed , you can set the jquery .animation duration to certain amount.

char ch = Character.MIN_VALUE;

The code above will initialize the variable ch with the minimum value that a char can have (i.e. \u0000).

in sql server 2008 r2 with ssis expression we have the trim function .

SQL Server Integration Services (SSIS) is a component of the Microsoft SQL Server database software that can be used to perform a broad range of data migration tasks.

you can find the complete description on this link

http://msdn.microsoft.com/en-us/library/ms139947.aspx

but this function have some limitation in itself which are also mentioned by msdn on that page. but this is in sql server 2008 r2

TRIM("   New York   ") .The return result is "New York".

If your field type is of json the following will work for you.

UPDATE 
table_name
SET field_name = field_name::jsonb - 'key' || '{"key":new_val}' 
WHERE field_name->>'key' = 'old_value'.

Operator '-' delete key/value pair or string element from left operand. Key/value pairs are matched based on their key value.

Operator '||' concatenate two jsonb values into a new jsonb value.

Since these are jsonb operators you just need to typecast to::jsonb

More info : JSON Functions and Operators

You can read my note here

I think it is good to categorize relations like this

When to use eager loading

1. In "one side" of one-to-many relations that you sure are used every where with main entity. like User property of an Article. Category property of a Product.
2. Generally When relations are not too much and eager loading will be good practice to reduce further queries on server.

When to use lazy loading

1. Almost on every "collection side" of one-to-many relations. like Articles of User or Products of a Category
2. You exactly know that you will not need a property instantly.

Note: like Transcendent said there may be disposal problem with lazy loading.

Short answer for the code in question is:

UPDATE `table` SET test=number

Here table is the table name and it's surrounded by grave accent (aka back-ticks `) as this is MySQL convention to escape keywords (and TABLE is a keyword in that case).

BEWARE, that this is pretty dangerous query which will wipe everything in column test in every row of your table replacing it by the number (regardless of it's value)

It is more common to use WHERE clause to limit your query to only specific set of rows:

UPDATE `products` SET `in_stock` = true WHERE `supplier_id` = 10

This guide explains in detail how to deploy Spring Boot app on Tomcat:
http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file

Essentially I needed to add following class:

public class WebInitializer extends SpringBootServletInitializer {   
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(App.class);
    }    
}

Also I added following property to POM:

<properties>        
    <start-class>mypackage.App</start-class>
</properties>

You could change the lists to sets and then compare both sets using the & function. eg:

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

if set(list1) & set(list2):
    print "Number was found"
else:
    print "Number not in list"

The "&" operator gives the intersection point between the two sets. If there is an intersection, a set with the intersecting points will be returned. If there is no intersecting points then an empty set will be returned.

When you evaluate an empty set/list/dict/tuple with the "if" operator in Python the boolean False is returned.

First off:

public class ProfileCollection implements Iterable<Profile> {

Second:

return m_Profiles.get(m_ActiveProfile);

HashSet is O(1) to access elements, so it certainly does matter. But maintaining order of the objects in the set isn't possible.

TreeSet is useful if maintaining an order(In terms of values and not the insertion order) matters to you. But, as you've noted, you're trading order for slower time to access an element: O(log n) for basic operations.

From the javadocs for TreeSet:

This implementation provides guaranteed log(n) time cost for the basic operations (add, remove and contains).

For what it is worth, i have ubuntu and many packages installed and it went in conflict with it.

For me the right answer was:

sudo -i -u postgres-xc
psql

I have dealt with this at talkstats.com in posts 94, 101 & 103 found in the thread: Share Your Code. As others have said Rstudio may be a better way to go. I store these functions in my .Rprofile and actually use them a but to automatically block out lines of code quickly.

Not quite as nice as you were hoping for but may be an approach.

Screenshot:

SizedBox.fromSize(
  size: Size(56, 56), // button width and height
  child: ClipOval(
    child: Material(
      color: Colors.orange, // button color
      child: InkWell(
        splashColor: Colors.green, // splash color
        onTap: () {}, // button pressed
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Icon(Icons.call), // icon
            Text("Call"), // text
          ],
        ),
      ),
    ),
  ),
)

Look if you have a typo error in your importation or your class generation, it could be simply that.

srand() seeds the random number generator. Without a seed, the generator is unable to generate the numbers you are looking for. As long as one's need for random numbers is not security-critical (e.g. any sort of cryptography), common practice is to use the system time as a seed by using the time() function from the <ctime> library as such: srand(time(0)). This will seed the random number generator with the system time expressed as a Unix timestamp (i.e. the number of seconds since the date 1/1/1970). You can then use rand() to generate a pseudo-random number.

Here is a quote from a duplicate question:

The reason is that a random number generated from the rand() function isn't actually random. It simply is a transformation. Wikipedia gives a better explanation of the meaning of pseudorandom number generator: deterministic random bit generator. Every time you call rand() it takes the seed and/or the last random number(s) generated (the C standard doesn't specify the algorithm used, though C++11 has facilities for specifying some popular algorithms), runs a mathematical operation on those numbers, and returns the result. So if the seed state is the same each time (as it is if you don't call srand with a truly random number), then you will always get the same 'random' numbers out.

SharedPreferences are stored in an xml file in the app data folder, i.e.

/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PREFS_NAME.xml

or the default preferences at:

/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PACKAGE_NAME_preferences.xml

SharedPreferences added during runtime are not stored in the Eclipse project.

Note: Accessing /data/data/<package_name> requires superuser privileges

You could use a regex, yes, but a simple string.Replace() will probably suffice.

 myString = myString.Replace("\r\n", string.Empty);

Here, in this post you will find the detailed code for establishing socket between devices or between two application in the same mobile.

You have to create two application to test below code.

In both application's manifest file, add below permission

Here is the latest method using the .map function in javascript.

Simple table code..

<table class="table table-hover">
    <thead class="thead-dark">
        <tr>
         <th scope="col">Tour</th>
         <th scope="col">Day</th>
         <th scope="col">Time</th>
         <th scope="col">Highlights</th>
         <th scope="col">Action</th>
       </tr>
    </thead>
  <tbody id="tableBody">
                            
  </tbody>

and here is javascript code to append something in the table body.

    const data = "some kind of json data or object of arrays";
                const tableData = data.map(function(value){
                    return (
                        `<tr>
                            <td>${value.Name}</td>
                            <td>${value.Day}</td>
                            <td>${value.Time}</td>
                            <td>${value.Highlights}</td>
                            <td class="text-center"><a class="btn btn-primary" href="route.html?id=${value.ID}" role="button">Details</a></td>
                        </tr>`
                    );
                }).join('');
            const tabelBody = document.querySelector("#tableBody");
                tableBody.innerHTML = tableData;

As an alternative and superior solution, you could use a custom counter in a before element. It involves no extra HTML markup. A CSS reset should be used alongside it, or at least styling removed from the ol element (list-style-type: none, reset margin), otherwise the element will have two counters.

<ol>
    <li>First line</li>
    <li>Second line</li>
</ol>

CSS:

ol {
    counter-reset: my-badass-counter;
}
ol li:before {
    content: counter(my-badass-counter, upper-alpha);
    counter-increment: my-badass-counter;
    margin-right: 5px;
    font-weight: bold;
}

An example: http://jsfiddle.net/xpAMU/1/

In my case, I had several instances of methods taking a closure with a signature like this (notice the optional array of dictionaries):

// 'results' being nil means "failure".
func queryItems(
    completion:( (results:[[String:AnyObject]]?)->(Void) )
    )
{
   // (async operation...)

...which I started to refactor into:

// 'results' is NEVER nil (at most, empty). Pass any errors to the 
//   failure: closure instead.
func queryItems(
    success:( (results:[[String:AnyObject]])->(Void) ),
    failure:( (error:NSError) -> (Void) )
    )
{
   // (async operation...)

...but did not finish, so some methods expected a closure with an optional argument and where being passed a non-optional one (or viceversa?), and I guess the compiler lost track.

There are few settings which define whether to use spaces or tabs.

So here are handy functions which can be defined in your ~/.vimrc file:

function! UseTabs()
  set tabstop=4     " Size of a hard tabstop (ts).
  set shiftwidth=4  " Size of an indentation (sw).
  set noexpandtab   " Always uses tabs instead of space characters (noet).
  set autoindent    " Copy indent from current line when starting a new line (ai).
endfunction

function! UseSpaces()
  set tabstop=2     " Size of a hard tabstop (ts).
  set shiftwidth=2  " Size of an indentation (sw).
  set expandtab     " Always uses spaces instead of tab characters (et).
  set softtabstop=0 " Number of spaces a <Tab> counts for. When 0, featuer is off (sts).
  set autoindent    " Copy indent from current line when starting a new line.
  set smarttab      " Inserts blanks on a <Tab> key (as per sw, ts and sts).
endfunction

Usage:

:call UseTabs()
:call UseSpaces()

To use it per file extensions, the following syntax can be used (added to .vimrc):

au! BufWrite,FileWritePre *.module,*.install call UseSpaces()

See also: Converting tabs to spaces.

Here is another snippet from Wikia which can be used to toggle between tabs and spaces:

" virtual tabstops using spaces
set shiftwidth=4
set softtabstop=4
set expandtab
" allow toggling between local and default mode
function TabToggle()
  if &expandtab
    set shiftwidth=8
    set softtabstop=0
    set noexpandtab
  else
    set shiftwidth=4
    set softtabstop=4
    set expandtab
  endif
endfunction
nmap <F9> mz:execute TabToggle()<CR>'z

It enables using 4 spaces for every tab and a mapping to F9 to toggle the settings.

One way to do this in Python 2, is to use raw_input():

raw_input("Press Enter to continue...")

In python3 it's just input()

var student = [];
var obj = {
    'first_name': name,
    'last_name': name,
    'age': age,
}
student.push(obj);

(Windows 10) I didn't like the path answers. I use choco package manager for node.js. Gulp would not fire for me unless it was:

1. Globally installed npm i -g gulp and local dir npm i --save-dev gulp

2. The problem persisted beyond this once, which was fixed by completely removing node.js and reinstalling it.

I didn't see any comments about local/global and node.js removal/reinstall.

You need

    str.CopyTo(data);
    data.Position = 0; // reset to beginning
    byte[] buf = new byte[data.Length];
    data.Read(buf, 0, buf.Length);  

And since your Test() method is imitating the client it ought to Close() or Dispose() the str Stream. And the memoryStream too, just out of principal.

SELECT to_char(to_date(month,'yyyy-mm'),'Mon yyyy'), nos
FROM (SELECT to_char(credit_date,'yyyy-mm') MONTH,count(*) nos
      FROM HCN
      WHERE   TRUNC(CREDIT_dATE) BEtween '01-jul-2014' AND '30-JUN-2015'
      AND CATEGORYCODECFR=22
      --AND CREDIT_NOTE_NO IS NOT  NULL
      AND CANCELDATE IS NULL
GROUP BY to_char(credit_date,'yyyy-mm')
ORDER BY to_char(credit_date,'yyyy-mm') ) mm

Output:

Jul 2014        49

To reset a specific file to the last-committed state (to discard uncommitted changes in a specific file):

git checkout thefiletoreset.txt

This is mentioned in the git status output:

(use "git checkout -- <file>..." to discard changes in working directory)

To reset the entire repository to the last committed state:

git reset --hard

To remove untracked files, I usually just delete all files in the working copy (but not the .git/ folder!), then do git reset --hard which leaves it with only committed files.

A better way is to use git clean (warning: using the -x flag as below will cause Git to delete ignored files):

git clean -d -x -f

will remove untracked files, including directories (-d) and files ignored by git (-x). Replace the -f argument with -n to perform a dry-run or -i for interactive mode, and it will tell you what will be removed.

Relevant links:

• git-reset man page
• git-clean man page
• git ready "cleaning up untracked files" (as Marko posted)
• Stack Overflow question "How to remove local (untracked) files from the current Git working tree")

.project

When a project is created in the workspace, a project description file is automatically generated that describes the project. The sole purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace.

.classpath

Classpath specifies which Java source files and resource files in a project are considered by the Java builder and specifies how to find types outside of the project. The Java builder compiles the Java source files into the output folder and also copies the resources into it.

Here is a way to do it in the shell:

FIELD=2
cut -f $FIELD * | sort| uniq -c |sort -nr

This is the sort of thing bash is great at.

Below is a 2-way extension class that supports:

• Timezone localization
• Input\output in seconds or milliseconds.

In OP's case, usage is:

DateTime.Now.ToUnixtime();

or

DateTime.UtcNow.ToUnixtime();

Even though a direct answer exists, I believe using a generic approach is better. Especially because it's most likely a project that needs a conversion like this, will also need these extensions anyway, so it's better to use the same tool for all.

    public static class UnixtimeExtensions
    {
        public static readonly DateTime UNIXTIME_ZERO_POINT = new DateTime(1970, 1, 1, 0, 0,0, DateTimeKind.Utc);

        /// <summary>
        /// Converts a Unix timestamp (UTC timezone by definition) into a DateTime object
        /// </summary>
        /// <param name="value">An input of Unix timestamp in seconds or milliseconds format</param>
        /// <param name="localize">should output be localized or remain in UTC timezone?</param>
        /// <param name="isInMilliseconds">Is input in milliseconds or seconds?</param>
        /// <returns></returns>
        public static DateTime FromUnixtime(this long value, bool localize = false, bool isInMilliseconds = true)
        {
            DateTime result;

            if (isInMilliseconds)
            {
                result = UNIXTIME_ZERO_POINT.AddMilliseconds(value);
            }
            else
            {
                result = UNIXTIME_ZERO_POINT.AddSeconds(value);
            }

            if (localize)
                return result.ToLocalTime();
            else
                return result;
        }

        /// <summary>
        /// Converts a DateTime object into a Unix time stamp
        /// </summary>
        /// <param name="value">any DateTime object as input</param>
        /// <param name="isInMilliseconds">Should output be in milliseconds or seconds?</param>
        /// <returns></returns>
        public static long ToUnixtime(this DateTime value, bool isInMilliseconds = true)
        {
            if (isInMilliseconds)
            {
                return (long)value.ToUniversalTime().Subtract(UNIXTIME_ZERO_POINT).TotalMilliseconds;
            }
            else
            {
                return (long)value.ToUniversalTime().Subtract(UNIXTIME_ZERO_POINT).TotalSeconds;
            }
        }
    }

Watermark solution in the original post works great. Thanks for it. In case anyone needs it, here is an angular directive for it.

(function () {
  'use strict';

  angular.module('app')
    .directive('placeholder', function () {
      return {
        restrict: 'A',
        link:     function (scope, element, attributes) {
          if (element.prop('nodeName') === 'TEXTAREA') {
            var placeholderText = attributes.placeholder.trim();

            if (placeholderText.length) {
              // support for both '\n' symbol and an actual newline in the placeholder element
              var placeholderLines = Array.prototype.concat
                .apply([], placeholderText.split('\n').map(line => line.split('\\n')))
                .map(line => line.trim());

              if (placeholderLines.length > 1) {
                element.watermark(placeholderLines.join('<br>\n'));
              }
            }
          }
        }
      };
    });
}());

Also it depends if you need to use a table element or not. You can imitate a table using CSS and make an A element the row

<div class="table" style="width:100%;">
  <a href="#" class="tr">
    <span class="td">
      cell 1
    </span>
    <span class="td">
      cell 2
    </span>
  </a>
</div>

css:

.table{display:table;}
.tr{display:table-row;}
.td{display:table-cell;}
.tr:hover{background-color:#ccc;}

JAVA 8

In plain java 8 you also have the possibility of using Streams/Collectors to do the job.

Map<String, String> myMap = Stream.of(
         new SimpleEntry<>("key1", "value1"),
         new SimpleEntry<>("key2", "value2"),
         new SimpleEntry<>("key3", "value3"))
        .collect(toMap(SimpleEntry::getKey, SimpleEntry::getValue));

This has the advantage of not creating an Anonymous class.

Note that the imports are:

import static java.util.stream.Collectors.toMap;
import java.util.AbstractMap.SimpleEntry;

Of course, as noted in other answers, in java 9 onwards you have simpler ways of doing the same.

Already tested by me, it works fine

For i =0 To ListBox2.items.count - 1

To get or set an attribute of an HTML element, you can use the element.attr() function in jQuery.

To get the href attribute, use the following code:

var a_href = $('selector').attr('href');

To set the href attribute, use the following code:

$('selector').attr('href','http://example.com');

In both cases, please use the appropriate selector. If you have set the class for the anchor element, use '.class-name' and if you have set the id for the anchor element, use '#element-id'.

gzip > stdin.gz perhaps? Otherwise, you need to flesh out your question.

SQL Developer seems to only output the DBMS_OUTPUT text when you have explicitly turned on the DBMS_OUTPUT window pane.

Go to (Menu) VIEW -> Dbms_output to invoke the pane.

Click on the Green Plus sign to enable output for your connection and then run the code.

EDIT: Don't forget to set the buffer size according to the amount of output you are expecting.

Since IGrouping<TKey, TElement> implements IEnumerable<TElement>, you can use SelectMany to put all the IEnumerables back into one IEnumerable all together:

List<smth> list = new List<smth>();
IEnumerable<IGrouping<int, smth>> groups = list.GroupBy(x => x.id);
IEnumerable<smth> smths = groups.SelectMany(group => group);
List<smth> newList = smths.ToList();

You're correct that the .swp file is used by vim for locking and as a recovery file.

Try putting set nobackup in your vimrc if you don't want these files. See the Vim docs for various backup related options if you want the whole scoop, or want to have .bak files instead...

Presumably from this site:

Internal Fragmentation Internal fragmentation occurs when the memory allocator leaves extra space empty inside of a block of memory that has been allocated for a client. This usually happens because the processor’s design stipulates that memory must be cut into blocks of certain sizes -- for example, blocks may be required to be evenly be divided by four, eight or 16 bytes. When this occurs, a client that needs 57 bytes of memory, for example, may be allocated a block that contains 60 bytes, or even 64. The extra bytes that the client doesn’t need go to waste, and over time these tiny chunks of unused memory can build up and create large quantities of memory that can’t be put to use by the allocator. Because all of these useless bytes are inside larger memory blocks, the fragmentation is considered internal.

External Fragmentation External fragmentation happens when the memory allocator leaves sections of unused memory blocks between portions of allocated memory. For example, if several memory blocks are allocated in a continuous line but one of the middle blocks in the line is freed (perhaps because the process that was using that block of memory stopped running), the free block is fragmented. The block is still available for use by the allocator later if there’s a need for memory that fits in that block, but the block is now unusable for larger memory needs. It cannot be lumped back in with the total free memory available to the system, as total memory must be contiguous for it to be useable for larger tasks. In this way, entire sections of free memory can end up isolated from the whole that are often too small for significant use, which creates an overall reduction of free memory that over time can lead to a lack of available memory for key tasks.

Another way to do it (if you use Node.js):

var input  = '32343630';
const output = Buffer.from(input, 'hex');
log(input + " -> " + output);  // Result: 32343630 -> 2460

hi body very late but i am writing

if(mylist.contains(value)){}

For a custom class to work properly in collections you'll have to implement/override the equals() methods of the class. For sorting also override compareTo().

See this article or google about how to implement those methods properly.

This is how I approached it. I did not want to "cross the bridge", as it has been removed from Xcode 6 beta 5 anyway, quick and dirty:

extension String {

    // converting a string to double
    func toDouble() -> Double? {

        // split the string into components
        var comps = self.componentsSeparatedByString(".")

        // we have nothing
        if comps.count == 0 {
            return nil
        }
        // if there is more than one decimal
        else if comps.count > 2 {
            return nil
        }
        else if comps[0] == "" || comps[1] == "" {
            return nil
        }

        // grab the whole portion
        var whole = 0.0
        // ensure we have a number for the whole
        if let w = comps[0].toInt() {
            whole = Double(w)
        }
        else {
            return nil
        }

        // we only got the whole
        if comps.count == 1 {

            return whole

        }

        // grab the fractional
        var fractional = 0.0
        // ensure we have a number for the fractional
        if let f = comps[1].toInt() {

            // use number of digits to get the power
            var toThePower = Double(countElements(comps[1]))

            // compute the fractional portion
            fractional = Double(f) / pow(10.0, toThePower)

        }
        else {
            return nil
        }

        // return the result
        return whole + fractional
    }

    // converting a string to float
    func toFloat() -> Float? {

        if let val = self.toDouble() {
            return Float(val)
        }
        else {
            return nil
        }

    }

}


// test it out
var str = "78.001"

if let val = str.toFloat() {
    println("Str in float: \(val)")
}
else {
    println("Unable to convert Str to float")
}

// now in double
if let val = str.toDouble() {
    println("Str in double: \(val)")
}
else {
    println("Unable to convert Str to double")
}

It could be interesting to know how to search for one unicode character. This command can help. You only need to know the code in UTF8

grep -v $'\u200d'

You need to understand that a Git repository is not just a tree of directories and files, but also stores a history of those trees - which might contain branches and merges.

When fetching from a repository, you will copy all or some of the branches there to your repository. These are then in your repository as "remote tracking branches", e.g. branches named like remotes/origin/master or such.

Fetching new commits from the remote repository will not change anything about your local working copy.

Your working copy has normally a commit checked out, called HEAD. This commit is usually the tip of one of your local branches.

I think you want to update your local branch (or maybe all the local branches?) to the corresponding remote branch, and then check out the latest branch.

To avoid any conflicts with your working copy (which might have local changes), you first clean everything which is not versioned (using git clean). Then you check out the local branch corresponding to the remote branch you want to update to, and use git reset to switch it to the fetched remote branch. (git pull will incorporate all updates of the remote branch in your local one, which might do the same, or create a merge commit if you have local commits.)

(But then you will really lose any local changes - both in working copy and local commits. Make sure that you really want this - otherwise better use a new branch, this saves your local commits. And use git stash to save changes which are not yet committed.)

Edit: If you have only one local branch and are tracking one remote branch, all you need to do is

git pull

from inside the working directory.

This will fetch the current version of all tracked remote branches and update the current branch (and the working directory) to the current version of the remote branch it is tracking.

This pulls back client info as well.

var get = function(u){
    var x = new XMLHttpRequest;
    x.open('GET', u, false);
    x.send();
    return x.responseText;
}

JSON.parse(get('http://ifconfig.me/all.json'))

This is what I needed to disable scrollbars while preserving scroll in Firefox, Chrome and Edge in :

          @-moz-document url-prefix() { /* Disable scrollbar Firefox */
            html{
              scrollbar-width: none;
            }
          }
          body {
            margin: 0; /* remove default margin */
            scrollbar-width: none; /* Also needed to disable scrollbar Firefox */
            -ms-overflow-style: none;  /* Disable scrollbar IE 10+ */
            overflow-y: scroll;
          }
          body::-webkit-scrollbar {
            width: 0px;
            background: transparent; /* Disable scrollbar Chrome/Safari/Webkit */
          }

This worked much better in my case.

HTML in PHP: <a href=".$link_address.">Link</a>

OK, here is a final solution based on ckramer's initial solution and palehorse's example that works in all of the browsers, including Opera. If you set history.navigationMode to 'compatible' then jQuery's ready function will fire on Back button operations in Opera as well as the other major browsers.

This page has more information.

Example:

history.navigationMode = 'compatible';
$(document).ready(function(){
  alert('test');
});

I tested this in Opera 9.5, IE7, FF3 and Safari and it works in all of them.

For anyone looking also for a solution for authentication, I would add on the scoped packages solution that you can have multiple lines in your .npmrc file:

//internal-npm.example.com:8080/:_authToken=xxxxxxxxxxxxxxx
//registry.npmjs.org/:_authToken=yyyyyyyyyy

Each line represents a different NPM registry

like this :

df.groupby('colour').size().plot(kind='bar')

It means you've already created a class.

For instance:

class Foo {}

// some code here

class Foo {}

That second Foo would throw the error.

here's a way using the SSSE3 instruction pshufb using its Intel intrinsic, assuming you have a multiple of 4 ints:

unsigned int *bswap(unsigned int *destination, unsigned int *source, int length) {
    int i;
    __m128i mask = _mm_set_epi8(12, 13, 14, 15, 8, 9, 10, 11, 4, 5, 6, 7, 0, 1, 2, 3);
    for (i = 0; i < length; i += 4) {
        _mm_storeu_si128((__m128i *)&destination[i],
        _mm_shuffle_epi8(_mm_loadu_si128((__m128i *)&source[i]), mask));
    }
    return destination;
}

EDIT: I am maintaining a similar, but more in-depth answer at: https://stackoverflow.com/a/28380690/895245

To see exactly what is happening, use nc -l or an ECHO server and an user agent like a browser or cURL.

Save the form to an .html file:

<form action="http://localhost:8000" method="post" enctype="multipart/form-data">
  <p><input type="text" name="text" value="text default">
  <p><input type="file" name="file1">
  <p><input type="file" name="file2">
  <p><button type="submit">Submit</button>
</form>

Create files to upload:

echo 'Content of a.txt.' > a.txt
echo '<!DOCTYPE html><title>Content of a.html.</title>' > a.html

Run:

nc -l localhost 8000

Open the HTML on your browser, select the files and click on submit and check the terminal.

nc prints the request received. Firefox sent:

Aternativelly, cURL should send the same POST request as your a browser form:

nc -l localhost 8000
curl -F "text=default" -F "[email protected]" -F "[email protected]" localhost:8000

You can do multiple tests with:

while true; do printf '' | nc -l localhost 8000; done

These days according to the golang github with for Ubuntu, it's possible to install the latest version of Go easily via a snap:

Using snaps also works quite well:

$ sudo snap install --classic go

Potentially preferable to fussing with outdated and/or 3rd party PPAs

Here's a response to your latest question about the difference between x86_64 and arm64:

• x86_64 architecture is required for running the 64bit simulator.

• arm64 architecture is required for running the 64bit device (iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini with Retina display).

The enums should not be qualified within the case label like what you have NDroid.guideView.GUIDE_VIEW_SEVEN_DAY, instead you should remove the qualification and use GUIDE_VIEW_SEVEN_DAY

Since vars passed through url are $_GET vars, you can use filter_input() function:

$id = filter_input(INPUT_GET, 'id', FILTER_SANITIZE_NUMBER_INT);
$othervar = filter_input(INPUT_GET, 'othervar', FILTER_SANITIZE_FULL_SPECIAL_CHARS);

It would store the values of each var and sanitize/validate them too.

and / or use ternary operator with assignment:

employee.FirstName = rdr.IsDBNull(indexFirstName))? 
                     String.Empty: rdr.GetString(indexFirstName);

replace the default (when null) value as appropriate for each property type...

360 degrees = 2*pi radians

That means deg2rad(x) = x*pi/180 and rad2deg(x) = 180x/pi;

Why use GROUP BY at all?

SELECT player_name, player_salary, player_salary*1.1 AS NewSalary
FROM players
ORDER BY player_salary DESC

In dplyr 0.3 this can be easily achieved using the distinct() method.

Here is an example:

distinct_df = df %>% distinct(field1)

You can get a vector of the distinct values with:

distinct_vector = distinct_df$field1

You can also select a subset of columns at the same time as you perform the distinct() call, which can be cleaner to look at if you examine the data frame using head/tail/glimpse.:

distinct_df = df %>% distinct(field1) %>% select(field1) distinct_vector = distinct_df$field1

There is no "convention" that requires table names to be singular.

For example, we had a table called "REJECTS" on a db used by a rating process, containing the records rejected from one run of the program, and I don't see any reason in not using plural for that table (naming it "REJECT" would have been just funny, or too optimistic).

About the other problem (quotes) it depends on the SQL dialect. Oracle doesn't require quotes around table names.

Sometimes

REPLACE(myString, CHAR(13) + CHAR(10), ' ')

won't work. In that case use the following snippet code:

REPLACE(REPLACE(myString, CHAR(13),''), CHAR(10), ' ')

Server.UrlEncode() is there to provide backward compatibility with Classic ASP,

Server.UrlEncode(str);

Is equivalent to:

HttpUtility.UrlEncode(str, Response.ContentEncoding);

document.location.href="/";

or

 window.location.href = "/";

According to the W3C, they are the same. In reality, for cross browser safety, you should use window.location rather than document.location.

See: http://www.w3.org/TR/Window/#window-location

(Note: I copied the difference explanation above, from this question.)

Liquibase was getting this error for me. I resolved this after I debugged and watched liquibase try to load the libraries and found that it was erroring on the manifest files for commons-codec-1.6.jar. Essentially, there is either a corrupt zip file somewhere in your path or there is a incompatible version being used. When I did an explore on Maven repository for this library, I found there were newer versions and added the newer version to the pom.xml. I was able to proceed at this point.

Limit the length of characters in a regular expression? ^[a-z]{6,15}$'

Limit length of characters or Numbers in a regular expression? ^[a-z | 0-9]{6,15}$'

I face Similar problem now I understand we have some more option : varStatus="loop", Here will be loop will variable which will hold the index of lop.

It can use for use to read for Zeor base index or 1 one base index.

${loop.count}` it will give 1 starting base index.

${loop.index} it will give 0 base index as normal Index of array start from 0.

For Example :

<c:forEach var="currentImage" items="${cityBannerImages}" varStatus="loop">
<picture>
   <source srcset="${currentImage}" media="(min-width: 1000px)"></source>
   <source srcset="${cityMobileImages[loop.count]}" media="(min-width:600px)"></source>
   <img srcset="${cityMobileImages[loop.count]}" alt=""></img>

The plugin's author says you should use "square brackets without the quotes", []

http://bassistance.de/2011/10/07/release-validation-plugin-1-9-0/

Release: Validation Plugin 1.9.0: "...Another change should make the setup of forms with hidden elements easier, these are now ignored by default (option “ignore” has “:hidden” now as default). In theory, this could break an existing setup. In the unlikely case that it actually does, you can fix it by setting the ignore-option to “[]” (square brackets without the quotes)."

To change this setting for all forms:

$.validator.setDefaults({ 
    ignore: [],
    // any other default options and/or rules
});

(It is not required that .setDefaults() be within the document.ready function)

OR for one specific form:

$(document).ready(function() {

    $('#myform').validate({
        ignore: [],
        // any other options and/or rules
    });

});

EDIT:

See this answer for how to enable validation on some hidden fields but still ignore others.

EDIT 2:

Before leaving comments that "this does not work", keep in mind that the OP is simply asking about the jQuery Validate plugin and his question has nothing to do with how ASP.NET, MVC, or any other Microsoft framework can alter this plugin's normal expected behavior. If you're using a Microsoft framework, the default functioning of the jQuery Validate plugin is over-written by Microsoft's unobtrusive-validation plugin.

If you're struggling with the unobtrusive-validation plugin, then please refer to this answer instead: https://stackoverflow.com/a/11053251/594235

I wonder, why you can't use that Google's Collection API with JDK 1.6. Does it say so? I think you can, there should not be any compatibility issues, as it is built for a lower version. The case would have been different if that were built for 1.6 and you are running 1.5.

Am I wrong somewhere?

Test for ':' first, then take test string up to ':' or end, depending on if it was found

Dim strResult As String

' Position of :
intPos = InStr(1, strTest, ":")
If intPos > 0 Then
    ' : found, so take up to :
    strResult = Left(strTest, intPos - 1)

I have been playing about with tmux today, trying to customised a little here and there, managed to get battery info displaying on the status right with a ruby script.

Copy the ruby script from http://natedickson.com/blog/2013/04/30/battery-status-in-tmux/ and save it as:

 battinfo.rb in ~/bin

To make it executable make sure to run:

chmod +x ~/bin/battinfo.rb

edit your ~/.tmux.config and include this line

set -g status-right "#[fg=colour155]#(pmset -g batt | ~/bin/battinfo.rb) | #[fg=colour45]%d %b %R"

The very simplest way would be to run Eclipse CDT on the Linux Box and use either X11-Forwarding or remote desktop software such as VNC.

This, of course, is only possible when you Eclipse is present on the Linux box and your network connection to the box is sufficiently fast.

The advantage is that, due to everything being local, you won't have synchronization issues, and you don't get any awkward cross-platform issues.

If you have no eclipse on the box, you could thinking of sharing your linux working directory via SMB (or SSHFS) and access it from your windows machine, but that would require quite some setup.

Both would be better than having two copies, especially when it's cross-platform.

Safer.

$galleries = array(1,2,5);
array_walk($galleries , 'intval');
$ids = implode(',', $galleries);
$sql = "SELECT * FROM galleries WHERE id IN ($ids)";

$1="" leaves a space as Ben Jackson mentioned, so use a for loop:

awk '{for (i=2; i<=NF; i++) print $i}' filename

So if your string was "one two three", the output will be:

two
three

If you want the result in one row, you could do as follows:

awk '{for (i=2; i<NF; i++) printf $i " "; print $NF}' filename

This will give you: "two three"

<script type="text/javascript">
    document.write(document.referrer);
</script>

document.referrer serves your purpose, but it doesn't work for Internet Explorer versions earlier than IE9.

It will work for other popular browsers, like Chrome, Mozilla, Opera, Safari etc.

Use the in operator:

testArray = 'key1' in obj;

Sidenote: What you got there, is actually no jQuery object, but just a plain JavaScript Object.

Wouldn't it just be a case of:

ArrayList<ArrayList<String>> outer = new ArrayList<ArrayList<String>>();
ArrayList<String> nodeList = new ArrayList<String>();

// Fill in nodeList here...

outer.add(nodeList);

Repeat as necesary.

This should return you a list in the format you specified.

There's one more vital difference as of jQuery 3.0 that can easily lead to unexpected behaviour and isn't mentioned in previous answers:

Consider the following code:

let d = $.Deferred();_x000D_
d.done(() => console.log('then'));_x000D_
d.resolve();_x000D_
console.log('now');

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0/jquery.min.js"></script>

this will output:

then
now

Now, replace done() by then() in the very same snippet:

var d = $.Deferred();_x000D_
d.then(() => console.log('then'));_x000D_
d.resolve();_x000D_
console.log('now');

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0/jquery.min.js"></script>

output is now:

now
then

So, for immediatly resolved deferreds, the function passed to done() will always be invoked in a synchronous manner, whereas any argument passed to then() is invoked async.

This differs from prior jQuery versions where both callbacks get called synchronously, as mentioned in the upgrade guide:

Another behavior change required for Promises/A+ compliance is that Deferred .then() callbacks are always called asynchronously. Previously, if a .then() callback was added to a Deferred that was already resolved or rejected, the callback would run immediately and synchronously.

In OnCreate method of your activity use this code:

    @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Now your orientation will be set to portrait and will never change.

This is the file we're all looking for (inside your Eclipse workspace):

.plugins/org.eclipse.core.runtime/.settings/org.eclipse.jdt.ui.prefs

You will find an @author tag with the name you want to change. Restart Eclipse and it will work.

For accents you have to use the Unicode format (e.g. '\u00E1' for á).

You can also modify the 'ini' file as prior answers suggest or set the user name var for a global solution. Or override the @author tag in the Preferences menu for a local solution. Those are both valid solutions to this problem.

But if you're looking for 'that' author name that is bothering most of us, is in that file.

This one works with NULL Values in Table and doesn't require substring operation at the end. COALESCE is not really well working with NULL values in table (if they will be there).

DECLARE @results VARCHAR(1000) = '' 
SELECT @results = @results + 
           ISNULL(CASE WHEN LEN(@results) = 0 THEN '' ELSE ',' END + [StudentId], '')
FROM Student WHERE condition = xyz

select @results

There are two kinds of cascades in Doctrine:

1) ORM level - uses cascade={"remove"} in the association - this is a calculation that is done in the UnitOfWork and does not affect the database structure. When you remove an object, the UnitOfWork will iterate over all objects in the association and remove them.

2) Database level - uses onDelete="CASCADE" on the association's joinColumn - this will add On Delete Cascade to the foreign key column in the database:

@ORM\JoinColumn(name="father_id", referencedColumnName="id", onDelete="CASCADE")

I also want to point out that the way you have your cascade={"remove"} right now, if you delete a Child object, this cascade will remove the Parent object. Clearly not what you want.

Follow the below steps in Eclipse.

1. Goto -> AVD Manager
2. Create/Edit the AVD.
3. Hardware > New:
4. Configures camera facing back
5. Click on the property value and choose = "webcam0".
6. Once done all the above the webcam should be connected. If it doesnt then you need to check your WebCam drivers.

If you need a dynamic choice field in django admin; This works for django >=2.1.

class CarAdminForm(forms.ModelForm):
    class Meta:
        model = Car

    def __init__(self, *args, **kwargs):
        super(CarForm, self).__init__(*args, **kwargs)

        # Now you can make it dynamic.
        choices = (
            ('audi', 'Audi'),
            ('tesla', 'Tesla')
        )

        self.fields.get('car_field').choices = choices

    car_field = forms.ChoiceField(choices=[])

@admin.register(Car)
class CarAdmin(admin.ModelAdmin):
    form = CarAdminForm

Hope this helps.
