You either need to specify an ID in the insert, or you need to configure the id column in the database to have Identity Specification = Yes.

You need to do this in transaction to ensure two simultaneous clients won't insert same fieldValue twice:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
BEGIN TRANSACTION
    DECLARE @id AS INT
    SELECT @id = tableId FROM table WHERE fieldValue=@newValue
    IF @id IS NULL
    BEGIN
       INSERT INTO table (fieldValue) VALUES (@newValue)
       SELECT @id = SCOPE_IDENTITY()
    END
    SELECT @id
COMMIT TRANSACTION

you can also use Double-checked locking to reduce locking overhead

DECLARE @id AS INT
SELECT @id = tableID FROM table (NOLOCK) WHERE fieldValue=@newValue
IF @id IS NULL
BEGIN
    SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
    BEGIN TRANSACTION
        SELECT @id = tableID FROM table WHERE fieldValue=@newValue
        IF @id IS NULL
        BEGIN
           INSERT INTO table (fieldValue) VALUES (@newValue)
           SELECT @id = SCOPE_IDENTITY()
        END
    COMMIT TRANSACTION
END
SELECT @id

As for why ISOLATION LEVEL SERIALIZABLE is necessary, when you are inside a serializable transaction, the first SELECT that hits the table creates a range lock covering the place where the record should be, so nobody else can insert the same record until this transaction ends.

Without ISOLATION LEVEL SERIALIZABLE, the default isolation level (READ COMMITTED) would not lock the table at read time, so between SELECT and UPDATE, somebody would still be able to insert. Transactions with READ COMMITTED isolation level do not cause SELECT to lock. Transactions with REPEATABLE READS lock the record (if found) but not the gap.

It's not exactly an operator, rather a keyword. And no, it doesn't do any runtime-magic.

jQuery is simply supporting the way CSS is written.

Also, it ensures that no matter how a browser returns a value, it will be understood

jQuery can equally interpret the CSS and DOM formatting of multiple-word properties. For example, jQuery understands and returns the correct value for both .css('background-color') and .css('backgroundColor').

from the sourcecode at http://mozilla.github.com/pdf.js/build/pdf.js

/**
 * This is the main entry point for loading a PDF and interacting with it.
 * NOTE: If a URL is used to fetch the PDF data a standard XMLHttpRequest(XHR)
 * is used, which means it must follow the same origin rules that any XHR does
 * e.g. No cross domain requests without CORS.
 *
 * @param {string|TypedAray|object} source Can be an url to where a PDF is
 * located, a typed array (Uint8Array) already populated with data or
 * and parameter object with the following possible fields:
 *  - url   - The URL of the PDF.
 *  - data  - A typed array with PDF data.
 *  - httpHeaders - Basic authentication headers.
 *  - password - For decrypting password-protected PDFs.
 *
 * @return {Promise} A promise that is resolved with {PDFDocumentProxy} object.
 */

So a standard XMLHttpRequest(XHR) is used for retrieving the document. The Problem with this is that XMLHttpRequests do not support data: uris (eg. data:application/pdf;base64,JVBERi0xLjUK...).

But there is the possibility of passing a typed Javascript Array to the function. The only thing you need to do is to convert the base64 string to a Uint8Array. You can use this function found at https://gist.github.com/1032746

var BASE64_MARKER = ';base64,';

function convertDataURIToBinary(dataURI) {
  var base64Index = dataURI.indexOf(BASE64_MARKER) + BASE64_MARKER.length;
  var base64 = dataURI.substring(base64Index);
  var raw = window.atob(base64);
  var rawLength = raw.length;
  var array = new Uint8Array(new ArrayBuffer(rawLength));

  for(var i = 0; i < rawLength; i++) {
    array[i] = raw.charCodeAt(i);
  }
  return array;
}

tl;dr

var pdfAsDataUri = "data:application/pdf;base64,JVBERi0xLjUK..."; // shortened
var pdfAsArray = convertDataURIToBinary(pdfAsDataUri);
PDFJS.getDocument(pdfAsArray)

You can also try to make service based on window.sessionStorage or window.localStorage to keep state information between page reloads. I use it in the web app which is partially made in AngularJS and page URL is changed in "the old way" for some parts of workflow. Web storage is supported even by IE8. Here is angular-webstorage for convenience.

For me, if I want to interact with the hidden div without seeing it disappear each time I leave the triggering element (a in that case) I must add:

div:hover {
    display: block;
}

Check out yowsup
https://github.com/tgalal/yowsup

Yowsup is a python library that allows you to do all the previous in your own app. Yowsup allows you to login and use the Whatsapp service and provides you with all capabilities of an official Whatsapp client, allowing you to create a full-fledged custom Whatsapp client.

A solid example of Yowsup's usage is Wazapp. Wazapp is full featured Whatsapp client that is being used by hundreds of thousands of people around the world. Yowsup is born out of the Wazapp project. Before becoming a separate project, it was only the engine powering Wazapp. Now that it matured enough, it was separated into a separate project, allowing anyone to build their own Whatsapp client on top of it. Having such a popular client as Wazapp, built on Yowsup, helped bring the project into a much advanced, stable and mature level, and ensures its continuous development and maintaince.

Yowsup also comes with a cross platform command-line frontend called yowsup-cli. yowsup-cli allows you to jump into connecting and using Whatsapp service directly from command line.

SonarQube reported Return an empty collection instead of null. and I had a problem with the error with casting as in the title of this question. I was able to get rid of both only using return XYZ.ToList().AsQueryable(); in a method with IQueryable like so:

public IQueryable<SomeType> MethodName (...) {
  IQueryable<SomeType> XYZ;
  ...
  return XYZ.ToList().AsQueryable();
}

Hope so it helps for those in a similar scenario(s).

In general, you can use a backslash at the end of a line in order for the command to continue on to the next line. However, there are cases where commands are implicitly continued, namely when the line ends with a token than cannot legally terminate a command. In that case, the shell knows that more is coming, and the backslash can be omitted. Some examples:

# In general
$ echo "foo" \
> "bar"
foo bar

# Pipes
$ echo foo |
> cat
foo

# && and ||
$ echo foo &&
> echo bar
foo
bar
$ false ||
> echo bar
bar

Different, but related, is the implicit continuation inside quotes. In this case, without a backslash, you are simply adding a newline to the string.

$ x="foo
> bar"
$ echo "$x"
foo
bar

With a backslash, you are again splitting the logical line into multiple logical lines.

$ x="foo\
> bar"
$ echo "$x"
foobar

You can create an html page with a form, having method="post" and action="yourdesiredurl" and open it with your browser.

As an alternative, there are some browser plugins for developers that allow you to do that, like Web Developer Toolbar for Firefox

Can also use:

find . -mindepth 1 -mtime +3 -delete

To not delete target directory

Yes it remains the same. but why not easily test it? Make an ArrayList, fill it and then retrieve the elements!

Generate a random integer between from(inclusive) and to(exclusive)

import java.util.Random

val random = Random()

fun rand(from: Int, to: Int) : Int {
    return random.nextInt(to - from) + from
}

For me, everything was working both in an emulator and on a physical device.

However, it stopped working for me when I set up a second machine to debug the same app in an emulator with a newer API level.

I did not realize that the fingerprint for that machine changed. After seeing the authentication failure error log in the Device Log I closely compared the fingerprint in my Google Developer Console with the one in the error message. That's when I saw the difference. After adding the new fingerprint to the Developer Console (in combination with the package name) my app started working as expected in the emulator on the new system.

So if you set up a new system, check your fingerprints again!

Have you checked strncpy?

char * strncpy ( char * destination, const char * source, size_t num );

You must realize that begin and end actually defines a num of bytes to be copied from one place to another.

GROUP BY col1, col2, col3

You can do that simple with Files.size(new File(filename).toPath()).

$("#your-modal-id").modal('hide');

Running this call via class ($(".my-modal")) won't work.

In the MasterPage.cs file add the property of Label like this:

public string ErrorMessage
{
    get
    {
        return lblMessage.Text;
    }
    set
    {
        lblMessage.Text = value;
    }
}

On your aspx page, just below the Page Directive add this:

<%@ Page Title="" Language="C#" MasterPageFile="Master Path Name"..... %>
<%@ MasterType VirtualPath="Master Path Name" %>   // Add this

And in your codebehind(aspx.cs) page you can then easily access the Label Property and set its text as required. Like this:

this.Master.ErrorMessage = "Your Error Message here";

In case that you still can't use "import" here is how I handled it: Just translate it to a node friendly require. Example:

import { parse } from 'node-html-parser';

Is the same as:

const parse = require('node-html-parser').parse;

the getText method returns a String, while the setText receives a String, so you can write it like label1.setText(nameField.getText()); in your listener.

If you CAST your data as a VARCHAR() instead of explicitly CONVERTing your data you can simply

SELECT REPLACE(CAST(CreatedDate AS VARCHAR(20)),'Jan  1 1900 12:00AM','')

The CAST will automatically return your Date then as Jun 18 2020 12:46PM fix length strings formats which you can additionally SUBSTRING()

SELECT SUBSTRING(REPLACE(CAST(CreatedDate  AS VARCHAR(20)),'Jan  1 1900 12:00AM',''),1,11)

Output

Jun 18 2020

Some compilers support compound literals as an extention, allowing this construct:

Customer customerRecords[2];
customerRecords[0] = (Customer){25, "Bob Jones"};
customerRecords[1] = (Customer){26, "Jim Smith"};

But it's rather unportable.

You can use Underscore.js. It really makes things simple.

For example, removing elements from an array, you need to do:

_.without([1, 2, 3], 2);

And the result will be [1, 3].

It reduces the code that you write using jQuery.grep, etc. in jQuery.

In my case. The issues is same reason. I see the problem is on proxy and firewall.

Here my solution
Fisrt ways:
1. install Proxy for Maven and Eclipse
2. Go to Locate the {user}/.m2/repository and Remove all the *.lastupdated files
3. Go back into Eclipse, Right-click on the project and select Maven > Update Project. > Select "Force Update of Snapshots/Releases".

If the project is still exist error. example: here is my issues after all above step

Failure to transfer org.apache.maven:maven-archiver:pom:2.5 from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven:maven-archiver:pom:2.5 from/to central (https://repo.maven.apache.org/maven2): Connect timed out

I use this solution useful for me:
1. Find repository in https://mvnrepository.com/
2. Copy dependency to my *.poml of project
example

<dependency>
    <groupId>org.apache.maven</groupId>
    <artifactId>maven-archiver</artifactId>
    <version>2.5</version>
</dependency>

3. Build project. the dependency missing will be downloaded to local repository.
4. Go back into Eclipse, Right-click on the project and select Maven > Update Project. > Select "Force Update of Snapshots/Releases".
=>> Error is resolved
5. I remove dependencies at step 2 after finished and resolved. Done

Can you use simply the SVG <title> element and the default browser rendering it conveys? (Note: this is not the same as the title attribute you can use on div/img/spans in html, it needs to be a child element named title)

rect {_x000D_
  width: 100%;_x000D_
  height: 100%;_x000D_
  fill: #69c;_x000D_
  stroke: #069;_x000D_
  stroke-width: 5px;_x000D_
  opacity: 0.5_x000D_
}

<p>Mouseover the rect to see the tooltip on supporting browsers.</p>_x000D_
_x000D_
<svg xmlns="http://www.w3.org/2000/svg">_x000D_
  <rect>_x000D_
    <title>Hello, World!</title>_x000D_
  </rect>_x000D_
</svg>

Alternatively, if you really want to show HTML in your SVG, you can embed HTML directly:

rect {_x000D_
  width: 100%;_x000D_
  height: 100%;_x000D_
  fill: #69c;_x000D_
  stroke: #069;_x000D_
  stroke-width: 5px;_x000D_
  opacity: 0.5_x000D_
}_x000D_
_x000D_
foreignObject {_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
svg div {_x000D_
  text-align: center;_x000D_
  line-height: 150px;_x000D_
}

<svg xmlns="http://www.w3.org/2000/svg">_x000D_
  <rect/>_x000D_
  <foreignObject>_x000D_
    <body xmlns="http://www.w3.org/1999/xhtml">_x000D_
      <div>_x000D_
        Hello, <b>World</b>!_x000D_
      </div>_x000D_
    </body>      _x000D_
  </foreignObject>_x000D_
</svg>

…but then you'd need JS to turn the display on and off. As shown above, one way to make the label appear at the right spot is to wrap the rect and HTML in the same <g> that positions them both together.

To use JS to find where an SVG element is on screen, you can use getBoundingClientRect(), e.g. http://phrogz.net/svg/html_location_in_svg_in_html.xhtml

First of all go to apache/bin/conf/httpd.conf and make sure that mod_deflate.so is enabled.

Then go to the .htaccess file and add this line:

SetOutputFilter DEFLATE

This should output all the content served as gzipped, i have tried it and it works.

This answer only really works if you don't need to do anything other than transferring the inner code (innerHTML) from one to the other:

// Define old parent
var oldParent = document.getElementById('old-parent');

// Define new parent
var newParent = document.getElementById('new-parent');

// Basically takes the inner code of the old, and places it into the new one
newParent.innerHTML = oldParent.innerHTML;

// Delete / Clear the innerHTML / code of the old Parent
oldParent.innerHTML = '';

Hope this helps!

string message = "This is test1";
string[] switchStrings = { "TEST1", "TEST2" };
switch (switchStrings.FirstOrDefault<string>(s => message.ToUpper().Contains(s)))
{
    case "TEST1":
        //Do work
        break;
    case "TEST2":
        //Do work
        break;
    default:
        //Do work
        break; 
}

You have to first convert your object literal to a Prototype Hash:

// Store your object literal
var obj = {foo: 1, bar: 2, barobj: {75: true, 76: false, 85: true}}

// Iterate like so.  The $H() construct creates a prototype-extended Hash.
$H(obj).each(function(pair){
  alert(pair.key);
  alert(pair.value);
});

This is called type assertion in TypeScript, and since TypeScript 1.6, there are two ways to express this:

// Original syntax
var markerSymbolInfo = <MarkerSymbolInfo> symbolInfo;

// Newer additional syntax
var markerSymbolInfo = symbolInfo as MarkerSymbolInfo;

Both alternatives are functionally identical. The reason for introducing the as-syntax is that the original syntax conflicted with JSX, see the design discussion here.

If you are in a position to choose, just use the syntax that you feel more comfortable with. I personally prefer the as-syntax as it feels more fluent to read and write.

"How does this and $scope work in AngularJS controllers?"

Short answer:

• this
  • When the controller constructor function is called, this is the controller.
  • When a function defined on a $scope object is called, this is the "scope in effect when the function was called". This may (or may not!) be the $scope that the function is defined on. So, inside the function, this and $scope may not be the same.
• $scope
  • Every controller has an associated $scope object.
  • A controller (constructor) function is responsible for setting model properties and functions/behaviour on its associated $scope.
  • Only methods defined on this $scope object (and parent scope objects, if prototypical inheritance is in play) are accessible from the HTML/view. E.g., from ng-click, filters, etc.

Long answer:

A controller function is a JavaScript constructor function. When the constructor function executes (e.g., when a view loads), this (i.e., the "function context") is set to the controller object. So in the "tabs" controller constructor function, when the addPane function is created

this.addPane = function(pane) { ... }

it is created on the controller object, not on $scope. Views cannot see the addPane function -- they only have access to functions defined on $scope. In other words, in the HTML, this won't work:

<a ng-click="addPane(newPane)">won't work</a>

After the "tabs" controller constructor function executes, we have the following:

The dashed black line indicates prototypal inheritance -- an isolate scope prototypically inherits from Scope. (It does not prototypically inherit from the scope in effect where the directive was encountered in the HTML.)

Now, the pane directive's link function wants to communicate with the tabs directive (which really means it needs to affect the tabs isolate $scope in some way). Events could be used, but another mechanism is to have the pane directive require the tabs controller. (There appears to be no mechanism for the pane directive to require the tabs $scope.)

So, this begs the question: if we only have access to the tabs controller, how do we get access to the tabs isolate $scope (which is what we really want)?

Well, the red dotted line is the answer. The addPane() function's "scope" (I'm referring to JavaScript's function scope/closures here) gives the function access to the tabs isolate $scope. I.e., addPane() has access to the "tabs IsolateScope" in the diagram above because of a closure that was created when addPane() was defined. (If we instead defined addPane() on the tabs $scope object, the pane directive would not have access to this function, and hence it would have no way to communicate with the tabs $scope.)

To answer the other part of your question: how does $scope work in controllers?:

Within functions defined on $scope, this is set to "the $scope in effect where/when the function was called". Suppose we have the following HTML:

<div ng-controller="ParentCtrl">
   <a ng-click="logThisAndScope()">log "this" and $scope</a> - parent scope
   <div ng-controller="ChildCtrl">
      <a ng-click="logThisAndScope()">log "this" and $scope</a> - child scope
   </div>
</div>

And the ParentCtrl (Solely) has

$scope.logThisAndScope = function() {
    console.log(this, $scope)
}

Clicking the first link will show that this and $scope are the same, since "the scope in effect when the function was called" is the scope associated with the ParentCtrl.

Clicking the second link will reveal this and $scope are not the same, since "the scope in effect when the function was called" is the scope associated with the ChildCtrl. So here, this is set to ChildCtrl's $scope. Inside the method, $scope is still the ParentCtrl's $scope.

Fiddle

I try to not use this inside of a function defined on $scope, as it becomes confusing which $scope is being affected, especially considering that ng-repeat, ng-include, ng-switch, and directives can all create their own child scopes.

It has to be a constant - the value has to be computable at the time that the procedure is created, and that one computation has to provide the value that will always be used.

Look at the definition of sys.all_parameters:

default_value sql_variant If has_default_value is 1, the value of this column is the value of the default for the parameter; otherwise, NULL.

That is, whatever the default for a parameter is, it has to fit in that column.

As Alex K pointed out in the comments, you can just do:

CREATE PROCEDURE [dbo].[problemParam] 
    @StartDate INT = NULL,
    @EndDate INT = NULL
AS  
BEGIN
   SET @StartDate = COALESCE(@StartDate,CONVERT(INT,(CONVERT(CHAR(8),GETDATE()-130,112))))

provided that NULL isn't intended to be a valid value for @StartDate.

As to the blog post you linked to in the comments - that's talking about a very specific context - that, the result of evaluating GETDATE() within the context of a single query is often considered to be constant. I don't know of many people (unlike the blog author) who would consider a separate expression inside a UDF to be part of the same query as the query that calls the UDF.

I think it's asking you to do this:

SELECT ID
FROM (SELECT ID,
             msisdn 
      FROM (SELECT * FROM TT2) as myalias
     ) as anotheralias;

But why would you write this query in the first place?

(Note: I'll append 'b' to indicate binary numbers here. All other numbers are given in decimal)

One way to think about things is in terms of something like scientific notation. We're used to seeing numbers expressed in scientific notation like, 6.022141 * 10^23. Floating point numbers are stored internally using a similar format - mantissa and exponent, but using powers of two instead of ten.

Your 61.0 could be rewritten as 1.90625 * 2^5, or 1.11101b * 2^101b with the mantissa and exponents. To multiply that by ten and (move the decimal point), we can do:

(1.90625 * 2^5) * (1.25 * 2^3) = (2.3828125 * 2^8) = (1.19140625 * 2^9)

or in with the mantissa and exponents in binary:

(1.11101b * 2^101b) * (1.01b * 2^11b) = (10.0110001b * 2^1000b) = (1.00110001b * 2^1001b)

Note what we did there to multiply the numbers. We multiplied the mantissas and added the exponents. Then, since the mantissa ended greater than two, we normalized the result by bumping the exponent. It's just like when we adjust the exponent after doing an operation on numbers in decimal scientific notation. In each case, the values that we worked with had a finite representation in binary, and so the values output by the basic multiplication and addition operations also produced values with a finite representation.

Now, consider how we'd divide 61 by 10. We'd start by dividing the mantissas, 1.90625 and 1.25. In decimal, this gives 1.525, a nice short number. But what is this if we convert it to binary? We'll do it the usual way -- subtracting out the largest power of two whenever possible, just like converting integer decimals to binary, but we'll use negative powers of two:

1.525         - 1*2^0   --> 1
0.525         - 1*2^-1  --> 1
0.025         - 0*2^-2  --> 0
0.025         - 0*2^-3  --> 0
0.025         - 0*2^-4  --> 0
0.025         - 0*2^-5  --> 0
0.025         - 1*2^-6  --> 1
0.009375      - 1*2^-7  --> 1
0.0015625     - 0*2^-8  --> 0
0.0015625     - 0*2^-9  --> 0
0.0015625     - 1*2^-10 --> 1
0.0005859375  - 1*2^-11 --> 1
0.00009765625...

Uh oh. Now we're in trouble. It turns out that 1.90625 / 1.25 = 1.525, is a repeating fraction when expressed in binary: 1.11101b / 1.01b = 1.10000110011...b Our machines only have so many bits to hold that mantissa and so they'll just round the fraction and assume zeroes beyond a certain point. The error you see when you divide 61 by 10 is the difference between:

1.100001100110011001100110011001100110011...b * 2^10b
and, say:
1.100001100110011001100110b * 2^10b

It's this rounding of the mantissa that leads to the loss of precision that we associate with floating point values. Even when the mantissa can be expressed exactly (e.g., when just adding two numbers), we can still get numeric loss if the mantissa needs too many digits to fit after normalizing the exponent.

We actually do this sort of thing all the time when we round decimal numbers to a manageable size and just give the first few digits of it. Because we express the result in decimal it feels natural. But if we rounded a decimal and then converted it to a different base, it'd look just as ugly as the decimals we get due to floating point rounding.

You've got the right idea, so here's how to go ahead: the onclick handlers run on the client side, in the browser, so you cannot call a PHP function directly. Instead, you need to add a JavaScript function that (as you mentioned) uses AJAX to call a PHP script and retrieve the data. Using jQuery, you can do something like this:

<script type="text/javascript">
function recp(id) {
  $('#myStyle').load('data.php?id=' + id);
}
</script>

<a href="#" onClick="recp('1')" > One   </a>
<a href="#" onClick="recp('2')" > Two   </a>
<a href="#" onClick="recp('3')" > Three </a>

<div id='myStyle'>
</div>

Then you put your PHP code into a separate file: (I've called it data.php in the above example)

<?php
  require ('myConnect.php');     
  $id = $_GET['id'];
  $results = mysql_query("SELECT para FROM content WHERE  para_ID='$id'");   
  if( mysql_num_rows($results) > 0 )
  {
   $row = mysql_fetch_array( $results );
   echo $row['para'];
  }
?>

Generally speaking:

all and any are functions that take some iterable and return True, if

• in the case of all(), no values in the iterable are falsy;
• in the case of any(), at least one value is truthy.

A value x is falsy iff bool(x) == False. A value x is truthy iff bool(x) == True.

Any non-booleans in the iterable will be fine — bool(x) will coerce any x according to these rules: 0, 0.0, None, [], (), [], set(), and other empty collections will yield False, anything else True. The docstring for bool uses the terms 'true'/'false' for 'truthy'/'falsy', and True/False for the concrete boolean values.

In your specific code samples:

You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:

if any(foobars) == big_foobar:

...because any(foobars) would first be evaluated to either True or False, and then that boolean value would be compared to big_foobar, which generally always gives you False (unless big_foobar coincidentally happened to be the same boolean value).

Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.

What you want instead is:

if any(x == big_foobar for x in foobars):

which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars, it compares the item to big_foobar and emits the resulting boolean into the resulting sequence:

tmp = (x == big_foobar for x in foobars)

then any walks over all items in tmp and returns True as soon as it finds the first truthy element. It's as if you did the following:

In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']                                        

In [2]: big_foobar = 'big'                                                                          

In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])        
Out[3]: True

Note: As DSM pointed out, any(x == y for x in xs) is equivalent to y in xs but the latter is more readable, quicker to write and runs faster.

Some examples:

In [1]: any(x > 5 for x in range(4))
Out[1]: False

In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True

In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True

In [4]: all([True, True, True, False, True])
Out[4]: False

Since I had to compile some source with 7 compatibility, because of some legacy system and ran into the same problem. I found out that in the gradle configuration there where two options set to java 8

sourceCompatibility = 1.8
targetCompatibility = 1.8

switching these to 1.7 solved the problem for me, keeping JAVA_HOME pointing to the installed JDK-7

sourceCompatibility = 1.7
targetCompatibility = 1.7

I found a solution that adds columns at runtime, and binds to a DataTable.

• How do I bind a WPF DataGrid to a variable number of columns?

Unfortunately, with 47 columns defined this way, it doesn't bind to the data fast enough for me. Any suggestions?

xaml

<DataGrid
  Name="dataGrid"
  AutoGenerateColumns="False"
  ItemsSource="{Binding}">
</DataGrid>

xaml.cs using System.Windows.Data;

if (table != null) // table is a DataTable
{
  foreach (DataColumn col in table.Columns)
  {
    dataGrid.Columns.Add(
      new DataGridTextColumn
      {
        Header = col.ColumnName,
        Binding = new Binding(string.Format("[{0}]", col.ColumnName))
      });
  }

  dataGrid.DataContext = table;
}

As mentioned by few users, below code can help find all the fields in a given class.

TestClass testObject= new TestClass().getClass();
Method[] methods = testObject.getMethods();
for (Method method:methods)
{
    String name=method.getName();
    if(name.startsWith("get"))
    {
        System.out.println(name.substring(3));
    }else if(name.startsWith("is"))
    {
        System.out.println(name.substring(2));
    }
}

However a more interesting approach is below:

With the help of Jackson library, I was able to find all class properties of type String/integer/double, and respective values in a Map class. (without using reflections api!)

TestClass testObject = new TestClass();
com.fasterxml.jackson.databind.ObjectMapper m = new com.fasterxml.jackson.databind.ObjectMapper();

Map<String,Object> props = m.convertValue(testObject, Map.class);

for(Map.Entry<String, Object> entry : props.entrySet()){
    if(entry.getValue() instanceof String || entry.getValue() instanceof Integer || entry.getValue() instanceof Double){
        System.out.println(entry.getKey() + "-->" + entry.getValue());
    }
}

A rather nice way to handle this for missing COM classes:

Dim o:Set o = Nothing
On Error Resume Next
Set o = CreateObject("foo.bar")
On Error Goto 0
If o Is Nothing Then
  Response.Write "Oups, foo.bar isn't installed on this server!"
Else
  Response.Write "Foo bar found, yay."
End If

May be its irrelevant answer but its working in my case...don't know what was wrong on my server...I just enable error log on Ubuntu 16.04 server.

//For PHP
error_reporting(E_ALL);
ini_set('display_errors', 1);

Ryley's answer is great, but I have text within the element. In order to rotate the text along with everything else, I used the border-spacing property instead of text-indent.

Also, to clarify a bit, in the element's style, set your initial value:

#foo {
    border-spacing: 0px;
}

Then in the animate chunk, your final value:

$('#foo').animate({  borderSpacing: -90 }, {
    step: function(now,fx) {
      $(this).css('transform','rotate('+now+'deg)');  
    },
    duration:'slow'
},'linear');

In my case, it rotates 90 degrees counter-clockwise.

Here is the live demo.

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

if(!empty($youtube) && empty($link)) {

}
else if(empty($youtube) && !empty($link)) {

}
else if(empty($youtube) && empty($link)) {
}

After researching a little bit all of the answers, I came up with a solution that worked just fine with my JavaScript functions across browsers (Including consoles / Dev Tools) :

<?php

 // PHP Version 7.2.1 (Windows 10 x86)

 function json2xml( $domNode ) {
  foreach( $domNode -> childNodes as $node) {
   if ( $node -> hasChildNodes() ) { json2xml( $node ); }
   else {
    if ( $domNode -> hasAttributes() && strlen( $domNode -> nodeValue ) ) {
     $domNode -> setAttribute( "nodeValue", $node -> textContent );
     $node -> nodeValue = "";
    }
   }
  }
 }

 function jsonOut( $file ) {
  $dom = new DOMDocument();
  $dom -> loadXML( file_get_contents( $file ) );
  json2xml( $dom );
  header( 'Content-Type: application/json' );
  return str_replace( "@", "", json_encode( simplexml_load_string( $dom -> saveXML() ), JSON_PRETTY_PRINT ) );
 }

 $output = jsonOut( 'https://boxelizer.com/assets/a1e10642e9294f39/b6f30987f0b66103.xml' );

 echo( $output );

 /*
  Or simply 
  echo( jsonOut( 'https://boxelizer.com/assets/a1e10642e9294f39/b6f30987f0b66103.xml' ) );
 */

?>

It basically creates a new DOMDocument, loads and XML file into it and traverses through each one of the nodes and children getting the data / parameters and exporting it into JSON without the annoying "@" signs.

Link to the XML file.

Actually I cannot reproduce the problem. The script as written in the question works fine, except for the case where $1 is empty.

However, there is a problem in the script related to redirection of stderr. Although the two forms &> and >& exist, in your case you want to use >&. You already redirected stdout, that's why the form &> does not work. You can easily verify it this way:

getent /etc/passwd username >/dev/null 2&>1
ls

You will see a file named 1 in the current directory. You want to use 2>&1 instead, or use this:

getent /etc/passwd username &>/dev/null

This also redirects stdout and stderr to /dev/null.

Warning Redirecting stderr to /dev/null might not be such a good idea. When things go wrong, you will have no clue why.

From Bash manual:

${#parameter}

The length in characters of the expanded value of parameter is substituted. If parameter is ‘’ or ‘@’, the value substituted is the number of positional parameters. If parameter is an array name subscripted by ‘’ or ‘@’, the value substituted is the number of elements in the array. If parameter is an indexed array name subscripted by a negative number, that number is interpreted as relative to one greater than the maximum index of parameter, so negative indices count back from the end of the array, and an index of -1 references the last element.

Length of strings, arrays, and associative arrays

string="0123456789"                   # create a string of 10 characters
array=(0 1 2 3 4 5 6 7 8 9)           # create an indexed array of 10 elements
declare -A hash
hash=([one]=1 [two]=2 [three]=3)      # create an associative array of 3 elements
echo "string length is: ${#string}"   # length of string
echo "array length is: ${#array[@]}"  # length of array using @ as the index
echo "array length is: ${#array[*]}"  # length of array using * as the index
echo "hash length is: ${#hash[@]}"    # length of array using @ as the index
echo "hash length is: ${#hash[*]}"    # length of array using * as the index

output:

string length is: 10
array length is: 10
array length is: 10
hash length is: 3
hash length is: 3

Dealing with $@, the argument array:

set arg1 arg2 "arg 3"
args_copy=("$@")
echo "number of args is: $#"
echo "number of args is: ${#@}"
echo "args_copy length is: ${#args_copy[@]}"

output:

number of args is: 3
number of args is: 3
args_copy length is: 3

If you use Modernizr, it is very easy to use Modernizr.touch as mentioned earlier.

However, I prefer using a combination of Modernizr.touch and user agent testing, just to be safe.

var deviceAgent = navigator.userAgent.toLowerCase();

var isTouchDevice = Modernizr.touch || 
(deviceAgent.match(/(iphone|ipod|ipad)/) ||
deviceAgent.match(/(android)/)  || 
deviceAgent.match(/(iemobile)/) || 
deviceAgent.match(/iphone/i) || 
deviceAgent.match(/ipad/i) || 
deviceAgent.match(/ipod/i) || 
deviceAgent.match(/blackberry/i) || 
deviceAgent.match(/bada/i));

function Tipsy(element, options) {
    this.$element = $(element);
    this.options = options;
    this.enabled = !isTouchDevice;
    this.fixTitle();
};

If you don't use Modernizr, you can simply replace the Modernizr.touch function above with ('ontouchstart' in document.documentElement)

Also note that testing the user agent iemobile will give you broader range of detected Microsoft mobile devices than Windows Phone.

I had the same issue when I tried to use git.

It is possible to install git without it. And I doubt that gcc on mac is truly dependent on XCode. And I don't want to use root to accept something unless I'm sure I need it.

I uninstalled XCode by navigating to the applications folder and dragging XCode to the trash.

Now my git commands work as usual. I'll re-install XCode if/when I truly need it.

Only using Session.Clear() when a user logs out can pose a security hole. As the session is still valid as far as the Web Server is concerned. It is then a reasonably trivial matter to sniff, and grab the session Id, and hijack that session.

For this reason, when logging a user out it would be safer and more sensible to use Session.Abandon() so that the session is destroyed, and a new session created (even though the logout UI page would be part of the new session, the new session would not have any of the users details in it and hijacking the new session would be equivalent to having a fresh session, hence it would be mute).

Short answer: Use the change event. Here's a couple of practical examples. Since I misread the question, I'll include jQuery examples along with plain JavaScript. You're not gaining much, if anything, by using jQuery though.

Single checkbox

Using querySelector.

var checkbox = document.querySelector("input[name=checkbox]");

checkbox.addEventListener('change', function() {
  if (this.checked) {
    console.log("Checkbox is checked..");
  } else {
    console.log("Checkbox is not checked..");
  }
});

<input type="checkbox" name="checkbox" />

Single checkbox with jQuery

$('input[name=checkbox]').change(function() {
  if ($(this).is(':checked')) {
    console.log("Checkbox is checked..")
  } else {
    console.log("Checkbox is not checked..")
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input type="checkbox" name="checkbox" />

Multiple checkboxes

Here's an example of a list of checkboxes. To select multiple elements we use querySelectorAll instead of querySelector. Then use Array.filter and Array.map to extract checked values.

// Select all checkboxes with the name 'settings' using querySelectorAll.
var checkboxes = document.querySelectorAll("input[type=checkbox][name=settings]");
let enabledSettings = []

/*
For IE11 support, replace arrow functions with normal functions and
use a polyfill for Array.forEach:
https://vanillajstoolkit.com/polyfills/arrayforeach/
*/

// Use Array.forEach to add an event listener to each checkbox.
checkboxes.forEach(function(checkbox) {
  checkbox.addEventListener('change', function() {
    enabledSettings = 
      Array.from(checkboxes) // Convert checkboxes to an array to use filter and map.
      .filter(i => i.checked) // Use Array.filter to remove unchecked checkboxes.
      .map(i => i.value) // Use Array.map to extract only the checkbox values from the array of objects.
      
    console.log(enabledSettings)
  })
});

<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Multiple checkboxes with jQuery

let checkboxes = $("input[type=checkbox][name=settings]")
let enabledSettings = [];

// Attach a change event handler to the checkboxes.
checkboxes.change(function() {
  enabledSettings = checkboxes
    .filter(":checked") // Filter out unchecked boxes.
    .map(function() { // Extract values using jQuery map.
      return this.value;
    }) 
    .get() // Get array.
    
  console.log(enabledSettings);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Here is a quick start to get the gears turning...

ParkingLot is a class.

ParkingSpace is a class.

ParkingSpace has an Entrance.

Entrance has a location or more specifically, distance from Entrance.

ParkingLotSign is a class.

ParkingLot has a ParkingLotSign.

ParkingLot has a finite number of ParkingSpaces.

HandicappedParkingSpace is a subclass of ParkingSpace.

RegularParkingSpace is a subclass of ParkingSpace.

CompactParkingSpace is a subclass of ParkingSpace.

ParkingLot keeps array of ParkingSpaces, and a separate array of vacant ParkingSpaces in order of distance from its Entrance.

ParkingLotSign can be told to display "full", or "empty", or "blank/normal/partially occupied" by calling .Full(), .Empty() or .Normal()

Parker is a class.

Parker can Park().

Parker can Unpark().

Valet is a subclass of Parker that can call ParkingLot.FindVacantSpaceNearestEntrance(), which returns a ParkingSpace.

Parker has a ParkingSpace.

Parker can call ParkingSpace.Take() and ParkingSpace.Vacate().

Parker calls Entrance.Entering() and Entrance.Exiting() and ParkingSpace notifies ParkingLot when it is taken or vacated so that ParkingLot can determine if it is full or not. If it is newly full or newly empty or newly not full or empty, it should change the ParkingLotSign.Full() or ParkingLotSign.Empty() or ParkingLotSign.Normal().

HandicappedParker could be a subclass of Parker and CompactParker a subclass of Parker and RegularParker a subclass of Parker. (might be overkill, actually.)

In this solution, it is possible that Parker should be renamed to be Car.

Here's an example of how you'd use filter within your AngularJS JavaScript (rather than in an HTML element).

In this example, we have an array of Country records, each containing a name and a 3-character ISO code.

We want to write a function which will search through this list for a record which matches a specific 3-character code.

Here's how we'd do it without using filter:

$scope.FindCountryByCode = function (CountryCode) {
    //  Search through an array of Country records for one containing a particular 3-character country-code.
    //  Returns either a record, or NULL, if the country couldn't be found.
    for (var i = 0; i < $scope.CountryList.length; i++) {
        if ($scope.CountryList[i].IsoAlpha3 == CountryCode) {
            return $scope.CountryList[i];
        };
    };
    return null;
};

Yup, nothing wrong with that.

But here's how the same function would look, using filter:

$scope.FindCountryByCode = function (CountryCode) {
    //  Search through an array of Country records for one containing a particular 3-character country-code.
    //  Returns either a record, or NULL, if the country couldn't be found.

    var matches = $scope.CountryList.filter(function (el) { return el.IsoAlpha3 == CountryCode; })

    //  If 'filter' didn't find any matching records, its result will be an array of 0 records.
    if (matches.length == 0)
        return null;

    //  Otherwise, it should've found just one matching record
    return matches[0];
};

Much neater.

Remember that filter returns an array as a result (a list of matching records), so in this example, we'll either want to return 1 record, or NULL.

Hope this helps.

var jQueryObject = $('<div></div>').html( string ).children();

This creates a dummy jQuery object in which you can put the string as HTML. Then, you get the children only.

While other answers have noted the differences correctly, note that if you are in fact returning a ViewResult only it is better to return the more specific type rather than the base ActionResult type. An obvious exception to this principle is when your method returns multiple types deriving from ActionResult.

For a full discussion of the reasons behind this principle please see the related discussion here: Must ASP.NET MVC Controller Methods Return ActionResult?

Inconsolata (http://www.levien.com/type/myfonts/inconsolata.html) is a great monospaced font for programming. Earlier versions tend to act weird on OS X, but the newer versions work out very well.

Your Promise is pending, complete it by

userToken.then(function(result){
console.log(result)
})

after your remaining code. All this code does is that .then() completes your promise & captures the end result in result variable & print result in console. Keep in mind, you cannot store the result in global variable. Hope that explanation might help you.

And if you are using typescript (gulpfile.ts) then do this for yargs (building on @Caio Cunha's excellent answer https://stackoverflow.com/a/23038290/1019307 and other comments above):

Install

npm install --save-dev yargs

typings install dt~yargs --global --save

.ts files

Add this to the .ts files:

import { argv } from 'yargs';

...

  let debug: boolean = argv.debug;

This has to be done in each .ts file individually (even the tools/tasks/project files that are imported into the gulpfile.ts/js).

Run

gulp build.dev --debug

Or under npm pass the arg through to gulp:

npm run build.dev -- --debug

In my case, /storage/emulated/0/ corresponds to my device's root path. For example, when i take a photo with my phone's default camera application, the images are saved automatically /store/emulated/0/DCIM/Camera/mypicname.jpeg

For example, suppose that you want to store your pictures in /Pictures directory, namely in Pictures directory which exist in root directory. So you use the below code.

File storageDir = Environment.getExternalStoragePublicDirectory( Environment.DIRECTORY_PICTURES );

If you want to save the images in DCIM or Downloads directory, give the below arguments to the Environment.getExternalStoragePublicDirectory() method shown above.

Environment.DIRECTORY_DCIM
Environment.DIRECTORY_Downloads

Then specify your image name :

String imageFileName = "JPEG_" + timeStamp + "_";

Then create the file object as shown below. You specify the suffix as the 2nd argument.

File image = File.createTempFile(
            imageFileName,  // prefix
            ".jpg",         // suffix
            storageDir      // directory
);

There is a subtle difference in terms of conflict management. In case of conflicts, a pull request in Github will result in a merge commit on the destination branch. In Gitlab, when a conflict is found, the modifications made will be on a merge commit on the source branch.

See https://docs.gitlab.com/ee/user/project/merge_requests/resolve_conflicts.html

"GitLab resolves conflicts by creating a merge commit in the source branch that is not automatically merged into the target branch. This allows the merge commit to be reviewed and tested before the changes are merged, preventing unintended changes entering the target branch without review or breaking the build."

Install the babel packages @babel/core and @babel/preset which will convert ES6 to a commonjs target as node js doesn't understand ES6 targets directly

npm install --save-dev @babel/core @babel/preset-env

Then you need to create one configuration file with name .babelrc in your project's root directory and add this code there

{ "presets": ["@babel/preset-env"] }

function ratio(w, h) {
    function mdc(w, h) {
        var resto;
        do {
            resto = w % h;

            w = h;
            h = resto;

        } while (resto != 0);

        return w;
    }

    var mdc = mdc(w, h);


    var width = w/mdc;
    var height = h/mdc;

    console.log(width + ':' + height);
}

You need to get the total contents size of each directory recursively to output. Also, you need to specify that the contents you're grabbing to measure are not directories, or you risk errors (as directories do not have a Length parameter).

Here's your script modified for the output you're looking for:

$colItems = Get-ChildItem $startFolder | Where-Object {$_.PSIsContainer -eq $true} | Sort-Object
foreach ($i in $colItems)
{
    $subFolderItems = Get-ChildItem $i.FullName -recurse -force | Where-Object {$_.PSIsContainer -eq $false} | Measure-Object -property Length -sum | Select-Object Sum
    $i.FullName + " -- " + "{0:N2}" -f ($subFolderItems.sum / 1MB) + " MB"
}

I think what you have missed here is this:

https://maven.apache.org/settings.html#Servers

The repositories for download and deployment are defined by the repositories and distributionManagement elements of the POM. However, certain settings such as username and password should not be distributed along with the pom.xml. This type of information should exist on the build server in the settings.xml.

This is the prefered way of using custom repos. So probably what is happening is that the url of this repo is in settings.xml of the build server.

Once you get hold of the url and credentials, you can put them in your machine here: ~/.m2/settings.xml like this:

<settings ...> 

        .
        .
        .
        <servers>
            <server>
              <id>internal-repository-group</id>
              <username>YOUR-USERNAME-HERE</username>
              <password>YOUR-PASSWORD-HERE</password>
            </server>
        </servers>
</settings>

EDIT:

You then need to refer this repository into project POM. The id internal-repository-group can be used in every project. You can setup multiple repos and credentials setting using different IDs in settings xml.

The advantage of this approach is that project can be shared without worrying about the credentials and don't have to mention the credentials in every project.

Following is a sample pom of a project using "internal-repository-group"

<repositories>
    <repository>
        <id>internal-repository-group</id>
        <name>repo-name</name>
        <url>http://project.com/yourrepourl/</url>

            <enabled>true</enabled>

flutter installation issue in Mac OS (Specific for Big Sur).

1. Cheak which shell is your default shell, That you have in the terminal.
2. To check default shell type command echo $SHELL.
3. for my specific issue I have the zsh as my default shell.
4. So I change my zsh as my default shell to bash.
5. To change the default shell enter the believe command.
6. chsh -s /bin/bash
7. Enter your password when you promoted
8. Now I have bash shell as my default.
9. Then I just follow the standard process for flutter setup in flutter’s official site.
10. And I have successfully configured the flutter in my Mac OS.

Extract the file in the desired location, for example:

—> $ cd ~/development —> $ unzip ~/Downloads/flutter_macos_1.22.5-stable.zip

Add the flutter tool to your path:

export PATH="$PATH:`pwd`/flutter/bin"

This command sets your PATH variable for the current terminal window only. To permanently add Flutter to your path see below.

—> Determine the directory where you placed the Flutter SDK. —> Open (or create) the rc file for your shell. Typing echo $SHELL in your Terminal tells you which shell you’re using.

This is a quite confusing way of using Apache configuration directives.

Technically, the first bit is equivalent to

Allow From All

This is because Order Deny,Allow makes the Deny directive evaluated before the Allow Directives. In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.

Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.

The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.

Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.

It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.

The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):

#
# The following lines prevent .htaccess and .htpasswd files from being 
# viewed by Web clients. 
#
<Files ~ "^\.ht">
    Order allow,deny
    Deny from all
    Satisfy all
</Files>

which forbids access to any file beginning by ".ht".

The equivalent Apache 2.4 configuration should look like:

<Files ~ "^\.ht">
    Require all denied
</Files>

it's also possible to create a unique constraint of more than 1 column:

ALTER TABLE the_table 
    ADD CONSTRAINT constraint_name UNIQUE (column1, column2);

In PHP there are a lot of variables that I should check. Is it the same on Go?

This has nothing to do with Go (or PHP for that matter). It just depends on what the client, proxy, load-balancer, or server is sending. Get the one you need depending on your environment.

http.Request.RemoteAddr contains the remote IP address. It may or may not be your actual client.

And is the request case sensitive? for example x-forwarded-for is the same as X-Forwarded-For and X-FORWARDED-FOR? (from req.Header.Get("X-FORWARDED-FOR"))

No, why not try it yourself? http://play.golang.org/p/YMf_UBvDsH

Node.js does not run in a browser, therefore you will not have a document object available. Actually, you will not even have a DOM tree at all. If you are a bit confused at this point, I encourage you to read more about it before going further.

There are a few methods you can choose from to do what you want.

Method 1: Serving the file directly via HTTP

Because you wrote about opening the file in the browser, why don't you use a framework that will serve the file directly as an HTTP service, instead of having a two-step process? This way, your code will be more dynamic and easily maintainable (not mentioning your HTML always up-to-date).

There are plenty frameworks out there for that :

• Http (Node native API)
• Connect
• koa
• Express (using Connect)
• Sails (build on Express)
• Geddy
• CompoundJS
• etc.

The most basic way you could do what you want is this :

var http = require('http');

http.createServer(function (req, res) {
  var html = buildHtml(req);

  res.writeHead(200, {
    'Content-Type': 'text/html',
    'Content-Length': html.length,
    'Expires': new Date().toUTCString()
  });
  res.end(html);
}).listen(8080);

function buildHtml(req) {
  var header = '';
  var body = '';

  // concatenate header string
  // concatenate body string

  return '<!DOCTYPE html>'
       + '<html><head>' + header + '</head><body>' + body + '</body></html>';
};

And access this HTML with http://localhost:8080 from your browser.

(Edit: you could also serve them with a small HTTP server.)

Method 2: Generating the file only

If what you are trying to do is simply generating some HTML files, then go simple. To perform IO access on the file system, Node has an API for that, documented here.

var fs = require('fs');

var fileName = 'path/to/file';
var stream = fs.createWriteStream(fileName);

stream.once('open', function(fd) {
  var html = buildHtml();

  stream.end(html);
});

Note: The buildHtml function is exactly the same as in Method 1.

Method 3: Dumping the file directly into stdout

This is the most basic Node.js implementation and requires the invoking application to handle the output itself. To output something in Node (ie. to stdout), the best way is to use console.log(message) where message is any string, or object, etc.

var html = buildHtml();

console.log(html);

Note: The buildHtml function is exactly the same as in Method 1 (again)

If your script is called html-generator.js (for example), in Linux/Unix based system, simply do

$ node html-generator.js > path/to/file

Conclusion

Because Node is a modular system, you can even put the buildHtml function inside it's own module and simply write adapters to handle the HTML however you like. Something like

var htmlBuilder = require('path/to/html-builder-module');

var html = htmlBuilder(options);
...

You have to think "server-side" and not "client-side" when writing JavaScript for Node.js; you are not in a browser and/or limited to a sandbox, other than the V8 engine.

Extra reading, learn about npm. Hope this helps.

You can also easily pass parameters to modal controller by added a new property with instance of modal and get it to modal controller. For example:

Following is my click event on which i want to open modal view.

 $scope.openMyModalView = function() {
            var modalInstance = $modal.open({
                    templateUrl: 'app/userDetailView.html',
                    controller: 'UserDetailCtrl as userDetail'
                });
                // add your parameter with modal instance
                modalInstance.userName = 'xyz';
        };

Modal Controller:

angular.module('myApp').controller('UserDetailCtrl', ['$modalInstance',
                function ($modalInstance) {
                    // get your parameter from modal instance
                    var currentUser = $modalInstance.userName;
                    // do your work...
                }]);

The tricky part is a regex that includes a dash as one of the valid characters in a character class. The dash has to come immediately after the start for a (normal) character class and immediately after the caret for a negated character class. If you need a close square bracket too, then you need the close square bracket followed by the dash. Mercifully, you only need dash, hence the notation chosen.

grep '^[-d]rwx.*[0-9]$' "$@"

See: Regular Expressions and grep for POSIX-standard details.

Update 03-Oct-19

new script that displays 10second countdown then launches chrome/chromiumn in fullscreen kiosk mode.

more updates to chrome required script update to allow autoplaying video with audio. Note --overscroll-history-navigation=0 isn't working currently will need to disable this flag by going to chrome://flags/#overscroll-history-navigation in your browser and setting to disabled.

@echo off
echo Countdown to application launch...
timeout /t 10
"C:\Program Files (x86)\chrome-win32\chrome.exe" --chrome --kiosk http://localhost/xxxx --incognito --disable-pinch --no-user-gesture-required --overscroll-history-navigation=0
exit

might need to set chrome://flags/#autoplay-policy if running an older version of chrome (60 below)

Update 11-May-16

There have been many updates to chrome since I posted this and have had to alter the script alot to keep it working as I needed.

Couple of issues with newer versions of chrome:

• built in pinch to zoom
• Chrome restore error always showing after forced shutdown
• auto update popup

Because of the restore error switched out to incognito mode as this launches a clear version all the time and does not save what the user was viewing and so if it crashes there is nothing to restore. Also the auto up in newer versions of chrome being a pain to try and disable I switched out to use chromium as it does not auto update and still gives all the modern features of chrome. Note make sure you download the top version of chromium this comes with all audio and video codecs as the basic version of chromium does not support all codecs.

Chromium download link

@echo off

echo Step 1 of 2: Waiting a few seconds before starting the Kiosk...

"C:\windows\system32\ping" -n 5 -w 1000 127.0.0.1 >NUL

echo Step 2 of 5: Waiting a few more seconds before starting the browser...

"C:\windows\system32\ping" -n 5 -w 1000 127.0.0.1 >NUL

echo Final 'invisible' step: Starting the browser, Finally...

"C:\Program Files (x86)\Google\Chromium\chrome.exe" --chrome --kiosk http://127.0.0.1/xxxx --incognito --disable-pinch --overscroll-history-navigation=0

exit

Outdated

I use this for exhibitions to lock down screens. I think its what your looking for.

• Start chrome and go to www.google.com drag and drop the url out onto the desktop
• rename it to something handy for this example google_homepage
• drop this now into your c directory, click on my computer c: and drop this file in there
• start chrome again go to settings and under on start up select open a specific page and set your home page here.

Next part is the script that I use to start close and restart chrome again in kiosk mode. The locations is where I have chrome installed so it might be abit different for you depending on your install.

Open your text editor of choice or just notepad and past the below code in, make sure its in the same format/order as below. Save it to your desktop as what ever you like so for this example chrome_startup_script.txt next right click it and rename, remove the txt from the end and put in bat instead. double click this to launch the script to see if its working correctly.

A command line box should appear and run through the script, chrome will start and then close down the reason to do this is to remove any error reports such as if the pc crashed, when chrome starts again without this it would show the yellow error bar at the top saying chrome did not shut down properly would you like to restore it. After a few seconds chrome should start again and in kiosk mode and will point to what ever homepage you have set.

@echo off
echo Step 1 of 5: Waiting a few seconds before starting the Kiosk...
"C:\windows\system32\ping" -n 31 -w 1000 127.0.0.1 >NUL
echo Step 2 of 5: Starting browser as a pre-start to delete error messages...
"C:\google_homepage.url"
echo Step 3 of 5: Waiting a few seconds before killing the browser task...
"C:\windows\system32\ping" -n 11 -w 1000 127.0.0.1 >NUL
echo Step 4 of 5: Killing the browser task gracefully to avoid session restore...
Taskkill /IM chrome.exe
echo Step 5 of 5: Waiting a few seconds before restarting the browser...
"C:\windows\system32\ping" -n 11 -w 1000 127.0.0.1 >NUL
echo Final 'invisible' step: Starting the browser, Finally...
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --kiosk --overscroll-history-navigation=0"
exit

Note: The number after the -n of the ping is the amount of seconds (minus one second) to wait before starting the link (or application in the next line)

Finally if this is all working then you can drag and drop the .bat file into the startup folder in windows and this script will launch each time windows starts.

Update:

With recent versions of chrome they have really got into enabling touch gestures, this means that swiping left or right on a touchscreen will cause the browser to go forward or backward in history. To prevent this we need to disable the history navigation on the back and forward buttons to do that add the following --overscroll-history-navigation=0 to the end of the script.

There is a pure CSS solution I'm currently using.

Add a body ID (or class) identifying your pages and your menu items, then use something like:

HTML:

<html>
    <body id="body_questions">
        <ul class="menu">
            <li id="questions">Question</li>
            <li id="tags">Tags</li>
            <li id="users">Users</li>
        </ul>
        ...
    </body>
</html>

CSS:

.menu li:hover,
#body_questions #questions,
#body_tags      #tags,
#body_users     #users {
    background-color: #f90;
}

By using lambdaj you can sort a collection of your contacts (for example by their name) as it follows

sort(contacts, on(Contact.class).getName());

or by their address:

sort(contacts, on(Contacts.class).getAddress());

and so on. More in general, it offers a DSL to access and manipulate your collections in many ways, like filtering or grouping your contacts based on some conditions, aggregate some of their property values, etc.

How about

sub foo()
  dim r As Range, rows As Long, i As Long
  Set r = ActiveSheet.Range("A1:Z50")
  rows = r.rows.Count
  For i = rows To 1 Step (-1)
    If WorksheetFunction.CountA(r.rows(i)) = 0 Then r.rows(i).Delete
  Next
End Sub

Try this

Option Explicit

Sub Sample()
    Dim i As Long
    Dim DelRange As Range

    On Error GoTo Whoa

    Application.ScreenUpdating = False

    For i = 1 To 50
        If Application.WorksheetFunction.CountA(Range("A" & i & ":" & "Z" & i)) = 0 Then
            If DelRange Is Nothing Then
                Set DelRange = Range("A" & i & ":" & "Z" & i)
            Else
                Set DelRange = Union(DelRange, Range("A" & i & ":" & "Z" & i))
            End If
        End If
    Next i

    If Not DelRange Is Nothing Then DelRange.Delete shift:=xlUp
LetsContinue:
    Application.ScreenUpdating = True

    Exit Sub
Whoa:
    MsgBox Err.Description
    Resume LetsContinue
End Sub

IF you want to delete the entire row then use this code

Option Explicit

Sub Sample()
    Dim i As Long
    Dim DelRange As Range

    On Error GoTo Whoa

    Application.ScreenUpdating = False

    For i = 1 To 50
        If Application.WorksheetFunction.CountA(Range("A" & i & ":" & "Z" & i)) = 0 Then
            If DelRange Is Nothing Then
                Set DelRange = Rows(i)
            Else
                Set DelRange = Union(DelRange, Rows(i))
            End If
        End If
    Next i

    If Not DelRange Is Nothing Then DelRange.Delete shift:=xlUp
LetsContinue:
    Application.ScreenUpdating = True

    Exit Sub
Whoa:
    MsgBox Err.Description
    Resume LetsContinue
End Sub

You can specify GLOBIGNORE and use the pattern *

GLOBIGNORE='ignore1:ignore2' scp -r source/* remoteurl:remoteDir

You may wish to have general rules which you combine or override by using export GLOBIGNORE, but for ad-hoc usage simply the above will do. The : character is used as delimiter for multiple values.

You'll find that in javascript, there are usually many different ways to do the same thing or find the same information. In your example, you are looking for some element that is guaranteed to always exist. window and document both fit the bill (with just a few differences).

From mozilla dev network:

addEventListener() registers a single event listener on a single target. The event target may be a single element in a document, the document itself, a window, or an XMLHttpRequest.

So as long as you can count on your "target" always being there, the only difference is what events you're listening for, so just use your favorite.

You'll have to pass your arguments as reference types.

#First create the variables (note you have to set them to something)
$global:var1 = $null
$global:var2 = $null
$global:var3 = $null

#The type of the reference argument should be of type [REF]
function foo ($a, $b, [REF]$c)
{
    # add $a and $b and set the requested global variable to equal to it
    # Note how you modify the value.
    $c.Value = $a + $b
}

#You can then call it like this:
foo 1 2 [REF]$global:var3

Spring security is a filter based framework, it plants a WALL(HttpFireWall) before your application in terms of proxy filters or spring managed beans. Your request has to pass through multiple filters to reach your API.

Sequence of execution in Spring Security

1. WebAsyncManagerIntegrationFilter Provides integration between the SecurityContext and Spring Web's WebAsyncManager.
   

2. SecurityContextPersistenceFilter This filter will only execute once per request, Populates the SecurityContextHolder with information obtained from the configured SecurityContextRepository prior to the request and stores it back in the repository once the request has completed and clearing the context holder.
   Request is checked for existing session. If new request, SecurityContext will be created else if request has session then existing security-context will be obtained from respository.

3. HeaderWriterFilter Filter implementation to add headers to the current response.

4. LogoutFilter If request url is /logout(for default configuration) or if request url mathces RequestMatcher configured in LogoutConfigurer then

   • clears security context.
   • invalidates the session
   • deletes all the cookies with cookie names configured in LogoutConfigurer
   • Redirects to default logout success url / or logout success url configured or invokes logoutSuccessHandler configured.

5. UsernamePasswordAuthenticationFilter

   • For any request url other than loginProcessingUrl this filter will not process further but filter chain just continues.
   • If requested URL is matches(must be HTTP POST) default /login or matches .loginProcessingUrl() configured in FormLoginConfigurer then UsernamePasswordAuthenticationFilter attempts authentication.
   • default login form parameters are username and password, can be overridden by usernameParameter(String), passwordParameter(String).
   • setting .loginPage() overrides defaults
   • While attempting authentication
     • an Authentication object(UsernamePasswordAuthenticationToken or any implementation of Authentication in case of your custom auth filter) is created.
     • and authenticationManager.authenticate(authToken) will be invoked
       
     • Note that we can configure any number of AuthenticationProvider authenticate method tries all auth providers and checks any of the auth provider supports authToken/authentication object, supporting auth provider will be used for authenticating. and returns Authentication object in case of successful authentication else throws AuthenticationException.
   • If authentication success session will be created and authenticationSuccessHandler will be invoked which redirects to the target url configured(default is /)
   • If authentication failed user becomes un-authenticated user and chain continues.

6. SecurityContextHolderAwareRequestFilter, if you are using it to install a Spring Security aware HttpServletRequestWrapper into your servlet container

7. AnonymousAuthenticationFilter Detects if there is no Authentication object in the SecurityContextHolder, if no authentication object found, creates Authentication object (AnonymousAuthenticationToken) with granted authority ROLE_ANONYMOUS. Here AnonymousAuthenticationToken facilitates identifying un-authenticated users subsequent requests.
   

DEBUG - /app/admin/app-config at position 9 of 12 in additional filter chain; firing Filter: 'AnonymousAuthenticationFilter'
DEBUG - Populated SecurityContextHolder with anonymous token: 'org.springframework.security.authentication.AnonymousAuthenticationToken@aeef7b36: Principal: anonymousUser; Credentials: [PROTECTED]; Authenticated: true; Details: org.springframework.security.web.authentication.WebAuthenticationDetails@b364: RemoteIpAddress: 0:0:0:0:0:0:0:1; SessionId: null; Granted Authorities: ROLE_ANONYMOUS' 

8. ExceptionTranslationFilter, to catch any Spring Security exceptions so that either an HTTP error response can be returned or an appropriate AuthenticationEntryPoint can be launched

9. FilterSecurityInterceptor
   There will be FilterSecurityInterceptor which comes almost last in the filter chain which gets Authentication object from SecurityContext and gets granted authorities list(roles granted) and it will make a decision whether to allow this request to reach the requested resource or not, decision is made by matching with the allowed AntMatchers configured in HttpSecurityConfiguration.

Consider the exceptions 401-UnAuthorized and 403-Forbidden. These decisions will be done at the last in the filter chain

• Un authenticated user trying to access public resource - Allowed
  
• Un authenticated user trying to access secured resource - 401-UnAuthorized
  
• Authenticated user trying to access restricted resource(restricted for his role) - 403-Forbidden
  

Note: User Request flows not only in above mentioned filters, but there are others filters too not shown here.(ConcurrentSessionFilter,RequestCacheAwareFilter,SessionManagementFilter ...)
It will be different when you use your custom auth filter instead of UsernamePasswordAuthenticationFilter.
It will be different if you configure JWT auth filter and omit .formLogin() i.e, UsernamePasswordAuthenticationFilter it will become entirely different case.

From Documentation ordering of filters is given as

• ChannelProcessingFilter
• ConcurrentSessionFilter
• SecurityContextPersistenceFilter
• LogoutFilter
• X509AuthenticationFilter
• AbstractPreAuthenticatedProcessingFilter
• CasAuthenticationFilter
• UsernamePasswordAuthenticationFilter
• ConcurrentSessionFilter
• OpenIDAuthenticationFilter
• DefaultLoginPageGeneratingFilter
• DefaultLogoutPageGeneratingFilter
• ConcurrentSessionFilter
• DigestAuthenticationFilter
• BearerTokenAuthenticationFilter
• BasicAuthenticationFilter
• RequestCacheAwareFilter
• SecurityContextHolderAwareRequestFilter
• JaasApiIntegrationFilter
• RememberMeAuthenticationFilter
• AnonymousAuthenticationFilter
• SessionManagementFilter
• ExceptionTranslationFilter
• FilterSecurityInterceptor
• SwitchUserFilter

UPDATED

I've updated your demo: http://jsfiddle.net/terryyounghk/QS56z/18/

Also, I've changed two ^= to *=. See http://api.jquery.com/category/selectors/

And note the :checked selector. See http://api.jquery.com/checked-selector/

function createcodes() {

    //run through each row
    $('.authors-list tr').each(function (i, row) {

        // reference all the stuff you need first
        var $row = $(row),
            $family = $row.find('input[name*="family"]'),
            $grade = $row.find('input[name*="grade"]'),
            $checkedBoxes = $row.find('input:checked');

        $checkedBoxes.each(function (i, checkbox) {
            // assuming you layout the elements this way, 
            // we'll take advantage of .next()
            var $checkbox = $(checkbox),
                $line = $checkbox.next(),
                $size = $line.next();

If copying to/from your desktop machine, use WinSCP, or if on Linux, Nautilus supports SCP via the Connect To Server option.

scp can only copy files to a machine running sshd, hence you need to run the client software on the remote machine from the one you are running scp on.

If copying on the command line, use:

# copy from local machine to remote machine
scp localfile user@host:/path/to/whereyouwant/thefile

or

# copy from remote machine to local machine
scp user@host:/path/to/remotefile localfile

Try this:

   SELECT *
FROM (SELECT * FROM (
    SELECT 
      id, 
      client_id, 
      create_time,
      ROW_NUMBER() OVER(PARTITION BY client_id ORDER BY create_time DESC) rn 
    FROM order
  ) 
  WHERE rn=1
  ORDER BY create_time desc) alias_name
WHERE rownum <= 100
ORDER BY rownum;

Or TOP:

SELECT TOP 2 * FROM Customers; //But not supported in Oracle

NOTE: I suppose that your internal query is fine. Please share your output of this.

Use Powershell! Built in cmdlets for managing processes. Examples here (hard way), here(built in) and here (more).

You definitely should not need the debug version of the CRT if you're compiling in "release" mode. You can tell they're the debug versions of the DLLs because they end with a d.

More to the point, the debug version is not redistributable, so it's not as simple as "packaging" it with your executable, or zipping up those DLLs.

Check to be sure that you're compiling all components of your application in "release" mode, and that you're linking the correct version of the CRT and any other libraries you use (e.g., MFC, ATL, etc.).

You will, of course, require msvcr100.dll (note the absence of the d suffix) and some others if they are not already installed. Direct your friends to download the Visual C++ 2010 Redistributable (or x64), or include this with your application automatically by building an installer.

You may be able to keep multiple tabs and more formatting information if you export to an OpenDocument Spreadsheet file (ods) or an older Excel format and import it with the ODS reader or the Excel reader you mentioned above.

Search your git directory if you already install git

Use git bash should be on your C:\Program Files\Git\bin depend on your installation location

If you already add the path just run sh on your cmd or open sh.exe

type ssh-keygen

Then just insert name and passphrase (You can just type empty string).

Since you tagged Java-ee as well - then YES it is possible.

and in core java as well it is possible using static blocks

and check this How can you run a Java program without main method?

Edit:
as already pointed out in other answers - it does not support from Java 7

JDK (Java Development Kit) :

• contains tools needed to develop the Java programs.
• You need JDK, if at all you want to write your own programs, and to compile them.
• JDK is mainly targeted for java development.

JRE (Java Runtime Environment)

Java Runtime Environment contains JVM, class libraries, and other supporting files. JRE is targeted for execution of Java files.

JVM (Java Virtual Machine)

The JVM interprets the byte code into the machine code depending upon the underlying operating system and hardware combination. It is responsible for all the things like garbage collection, array bounds checking, etc… Java Virtual Machine provides a platform-independent way of executing code.

You need to add the "global" flag to your regex:

s.replace(new RegExp("[0-9]", "g"), "X")

or, perhaps prettier, using the built-in literal regexp syntax:

.replace(/[0-9]/g, "X")

After a long Google, I came to know that javac.exe will be inside JDK(C:\Program Files\Java\jdk(version number)\bin) not inside JRE (C:\Program Files (x86)\Java\jre7\bin) "JRE doesn't come with a compiler. It(JRE) is simply a java runtime environment. What you need is the Java development kit." in order to use compiler javac

javac will not work if you are pointing bin inside jre

In order to use javac in cmd , JDK must be installed in your system...

For javac path

path = C:\Program Files (x86)\Java\jre7\bin this is wrong

path = C:\Program Files\Java\jdk(version number)\bin this is correct

Make sure that "javac.exe" is inside your "C:\Program Files\Java\jdk(version number)\bin"

Don't get confused with JRE and JDK both are totally different

if you don't have JDK pls download from this link

https://jdk.java.net/

or

simply use the form_validation class of codeigniter:

strip_image_tags($str).

$this->load->library('form_validation');
$this->form_validation->set_rules('nombre_campo', 'label', 'strip_image_tags');

You need to commit at least one time on master before creating a new branch.

Just git branch without options.

From the manpage:

With no arguments, existing branches are listed and the current branch will be highlighted with an asterisk.

Run this query and you'll probably get what you're looking for:

SELECT table_schema "DB Name",
        ROUND(SUM(data_length + index_length) / 1024 / 1024, 1) "DB Size in MB" 
FROM information_schema.tables 
GROUP BY table_schema; 

This query comes from the mysql forums, where there are more comprehensive instructions available.

forever might be of interest to you. It will run your .js-File 24/7 with logging options. Here are two snippets from the help text:

[Long Running Process] The forever process will continue to run outputting log messages to the console. ex. forever -o out.log -e err.log my-script.js

and

[Daemon] The forever process will run as a daemon which will make the target process start in the background. This is extremely useful for remote starting simple node.js scripts without using nohup. It is recommended to run start with -o -l, & -e. ex. forever start -l forever.log -o out.log -e err.log my-daemon.js forever stop my-daemon.js

Strings in C# are immutable and in some sense it means that they are fixed-size.
However you cannot constrain a string variable to only accept n-character strings. If you define a string variable, it can be assigned any string. If truncating strings (or throwing errors) is essential part of your business logic, consider doing so in your specific class' property setters (that's what Jon suggested, and it's the most natural way of creating constraints on values in .NET).

If you just want to make sure isn't too long (e.g. when passing it as a parameter to some legacy code), truncate it manually:

const int MaxLength = 5;


var name = "Christopher";
if (name.Length > MaxLength)
    name = name.Substring(0, MaxLength); // name = "Chris"

Unless it is the most trivial case, there is only one sane way to use command line options in Ruby. It is called docopt and documented here.

What is amazing with it, is it's simplicity. All you have to do, is specify the "help" text for your command. What you write there will then be auto-parsed by the standalone (!) ruby library.

From the example:

#!/usr/bin/env ruby
require 'docopt.rb'

doc = <<DOCOPT
Usage: #{__FILE__} --help
       #{__FILE__} -v...
       #{__FILE__} go [go]
       #{__FILE__} (--path=<path>)...
       #{__FILE__} <file> <file>

Try: #{__FILE__} -vvvvvvvvvv
     #{__FILE__} go go
     #{__FILE__} --path ./here --path ./there
     #{__FILE__} this.txt that.txt

DOCOPT

begin
  require "pp"
  pp Docopt::docopt(doc)
rescue Docopt::Exit => e
  puts e.message
end

The output:

$ ./counted_example.rb -h
Usage: ./counted_example.rb --help
       ./counted_example.rb -v...
       ./counted_example.rb go [go]
       ./counted_example.rb (--path=<path>)...
       ./counted_example.rb <file> <file>

Try: ./counted_example.rb -vvvvvvvvvv
     ./counted_example.rb go go
     ./counted_example.rb --path ./here --path ./there
     ./counted_example.rb this.txt that.txt

$ ./counted_example.rb something else
{"--help"=>false,
 "-v"=>0,
 "go"=>0,
 "--path"=>[],
 "<file>"=>["something", "else"]}

$ ./counted_example.rb -v
{"--help"=>false, "-v"=>1, "go"=>0, "--path"=>[], "<file>"=>[]}

$ ./counted_example.rb go go
{"--help"=>false, "-v"=>0, "go"=>2, "--path"=>[], "<file>"=>[]}

Enjoy!

The issue stems from your Angular code:

When withCredentials is set to true, it is trying to send credentials or cookies along with the request. As that means another origin is potentially trying to do authenticated requests, the wildcard ("*") is not permitted as the "Access-Control-Allow-Origin" header.

You would have to explicitly respond with the origin that made the request in the "Access-Control-Allow-Origin" header to make this work.

I would recommend to explicitly whitelist the origins that you want to allow to make authenticated requests, because simply responding with the origin from the request means that any given website can make authenticated calls to your backend if the user happens to have a valid session.

I explain this stuff in this article I wrote a while back.

So you can either set withCredentials to false or implement an origin whitelist and respond to CORS requests with a valid origin whenever credentials are involved

ffmpeg -codecs

should give you all the info about the codecs available.

You will see some letters next to the codecs:

Codecs:
 D..... = Decoding supported
 .E.... = Encoding supported
 ..V... = Video codec
 ..A... = Audio codec
 ..S... = Subtitle codec
 ...I.. = Intra frame-only codec
 ....L. = Lossy compression
 .....S = Lossless compression

From http://docs.python-requests.org/en/latest/user/quickstart/

url = 'https://api.github.com/some/endpoint'
payload = {'some': 'data'}
headers = {'content-type': 'application/json'}

r = requests.post(url, data=json.dumps(payload), headers=headers)

You just need to create a dict with your headers (key: value pairs where the key is the name of the header and the value is, well, the value of the pair) and pass that dict to the headers parameter on the .get or .post method.

So more specific to your question:

headers = {'foobar': 'raboof'}
requests.get('http://himom.com', headers=headers)

You could follow maven's standard project layout. You don't have to actually use maven, but it would make the transition easier in the future (if necessary). Plus, other developers will be used to seeing that layout, since many open source projects are layed out this way,

This works to take out the \n (new line) off a item in a list it just takes the first item in string off

def remove_end(s):
    templist=[]
    for i in s:
        templist.append(i)
    return(templist[0])

I tried to do something similar and used a workaround solution: I thought about implicit and explicit operator on structure: The idea is to wrap the Type in a structure that can be converted into Type implicitly.

Here is such a structure:

public struct InterfaceType { private Type _type;

public InterfaceType(Type type)
{
    CheckType(type);
    _type = type;
}

public static explicit operator Type(InterfaceType value)
{
    return value._type;
}

public static implicit operator InterfaceType(Type type)
{
    return new InterfaceType(type);
}

private static void CheckType(Type type)
{
    if (type == null) throw new NullReferenceException("The type cannot be null");
    if (!type.IsInterface) throw new NotSupportedException(string.Format("The given type {0} is not an interface, thus is not supported", type.Name));
}

}

basic usage:

// OK
InterfaceType type1 = typeof(System.ComponentModel.INotifyPropertyChanged);

// Throws an exception
InterfaceType type2 = typeof(WeakReference);

You have to imagine your own mecanism around this, but an example could be a method taken a InterfaceType in parameter instead of a type

this.MyMethod(typeof(IMyType)) // works
this.MyMethod(typeof(MyType)) // throws exception

A method to override that should returns interface types:

public virtual IEnumerable<InterfaceType> GetInterfaces()

There are maybe things to do with generics also, but I didn't tried

Hope this can help or gives ideas :-)

If you want to find out how to set-up a non-native cross compile, I found this useful:

On the target machine,

% gcc -march=native -Q --help=target | grep march
-march=                               core-avx-i

Then use this on the build machine:

% gcc -march=core-avx-i ...

You can start by reading the data structure alignment wikipedia article to get a better understanding of data alignment.

From the wikipedia article:

Data alignment means putting the data at a memory offset equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory. To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

From 6.54.8 Structure-Packing Pragmas of the GCC documentation:

For compatibility with Microsoft Windows compilers, GCC supports a set of #pragma directives which change the maximum alignment of members of structures (other than zero-width bitfields), unions, and classes subsequently defined. The n value below always is required to be a small power of two and specifies the new alignment in bytes.

1. #pragma pack(n) simply sets the new alignment.
2. #pragma pack() sets the alignment to the one that was in effect when compilation started (see also command line option -fpack-struct[=] see Code Gen Options).
3. #pragma pack(push[,n]) pushes the current alignment setting on an internal stack and then optionally sets the new alignment.
4. #pragma pack(pop) restores the alignment setting to the one saved at the top of the internal stack (and removes that stack entry). Note that #pragma pack([n]) does not influence this internal stack; thus it is possible to have #pragma pack(push) followed by multiple #pragma pack(n) instances and finalized by a single #pragma pack(pop).

Some targets, e.g. i386 and powerpc, support the ms_struct #pragma which lays out a structure as the documented __attribute__ ((ms_struct)).

1. #pragma ms_struct on turns on the layout for structures declared.
2. #pragma ms_struct off turns off the layout for structures declared.
3. #pragma ms_struct reset goes back to the default layout.

By default, plot does show axes, unless you've modified some settings. Try the following

hold on; % make sure no new plot window is created on every plot command
axes(); % produce plot window with axes
plot(% whatever your plot command is);
plot([0 10], [0 0], 'k-'); % plot the horizontal line

Running example on Stackblitz

There are a lot of implementations that can be used. The most obvious seems to be something like this:

String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g, "");
};

" foo bar ".trim();  // "foo bar"

Explicit Wait

public static  WebDriverWait wait = new WebDriverWait(driver, 60);

Example:

wait.until(ExpectedConditions.visibilityOfElementLocated(UiprofileCre.UiaddChangeUserLink));

You can' just add a class to each of your DIVs and apply the rule to the class in this way:

HTML:

<div class="myclass" id="s1">...</div>
<div class="myclass" id="s2">...</div>

CSS:

//css
.myclass
{
   ...
}

To complement Justus Thane's helpful answer:

• As Joey notes in a comment, PowerShell has a powerful, regex-based -split operator.

  • In its unary form (-split '...'), -split behaves like awk's default field splitting, which means that:
    • Leading and trailing whitespace is ignored.
    • Any run of whitespace (e.g., multiple adjacent spaces) is treated as a single separator.

• In PowerShell v4+ an expression-based - and therefore faster - alternative to the ForEach-Object cmdlet became available: the .ForEach() array (collection) method, as described in this blog post (alongside the .Where() method, a more powerful, expression-based alternative to Where-Object).

Here's a solution based on these features:

PS> (-split '   One      for the money   ').ForEach({ "token: [$_]" })
token: [One]
token: [for]
token: [the]
token: [money]

Note that the leading and trailing whitespace was ignored, and that the multiple spaces between One and for were treated as a single separator.

This mimics most of the behavior your looking for:

  <!--

     I found this works fairly well.

  -->

  <!-- On page load, be sure that something else has focus. -->
  <body onload="document.getElementById('name').focus();">
  <input id=name type=text>

  <!-- This div is for demonstration only.  The parent container may be anything -->
  <div style="height:50; width:100px; border:1px solid red;">

  <!-- Note: static width, absolute position but no top or left specified, Z-Index +1 -->
  <select
   style="width:96px; position:absolute; z-index:+1;"
   onactivate="this.style.width='auto';"
   onchange="this.blur();"
   onblur="this.style.width='96px';">
  <!-- "activate" happens before all else and "width='auto'" expands per content -->
  <!-- Both making a selection and moving to another control should return static width -->

  <option>abc</option>
  <option>abcdefghij</option>
  <option>abcdefghijklmnop</option>
  <option>abcdefghijklmnopqrstuvwxyz</option>

  </select>

  </div>

  </body>

  </html>

This will override some of the key-press behavior.

The finalizeQueue may be too long

i think that java may require GC.SuppressFinalize() & GC.ReRegisterForFinalize() to let user reduce the finalizedQueue length explicitly

if the JVM' source code is available, may implement these method ourself, such as android ROM maker

The find / sort solution works great until the number of files gets really large (like an entire file system). Use awk instead to just keep track of the most recent file:

find $DIR -type f -printf "%T@ %p\n" | 
awk '
BEGIN { recent = 0; file = "" }
{
if ($1 > recent)
   {
   recent = $1;
   file = $0;
   }
}
END { print file; }' |
sed 's/^[0-9]*\.[0-9]* //'

With Java 8's lambdas, a convenient way is to use

org.mockito.invocation.InvocationOnMock

when(client.deleteByQuery(anyString(), anyString())).then(invocationOnMock -> {
    assertEquals("myCollection", invocationOnMock.getArgument(0));
    assertThat(invocationOnMock.getArgument(1), Matchers.startsWith("id:"));
}

If you look down the demo page a bit, you'll see a "Restricting Datepicker" section. Use the dropdown to specify the "Year dropdown shows last 20 years" demo , and hit view source:

$("#restricting").datepicker({ 
    yearRange: "-20:+0", // this is the option you're looking for
    showOn: "both", 
    buttonImage: "templates/images/calendar.gif", 
    buttonImageOnly: true 
});

You'll want to do the same (obviously changing -20 to -100 or something).

The Windows shell (assuming you're using CMD.exe) uses %ProgramFiles% to point to the Program Files folder, no matter where it is. Since the default Windows file opener accounts for environment variables like this, if the program was well-written, it should support this.

Also, it could be worth using relative addresses. If the program you're using is installed correctly, it should already be in the Program Files folder, so you could just refer to the configuration file as .\config_file.txt if its in the same directory as the program, or ..\other_program\config_file.txt if its in a directory different than the other program. This would apply not only on Windows but on almost every modern operating system, and will work properly if you have the "Start In" box properly set, or you run it directly from its folder.

_{Old question but adding answer so that one can get help}

Its two step process:

Suppose, a table1 has a foreign key with column name fk_table2_id, with constraint name fk_name and table2 is referred table with key t2 (something like below in my diagram).

   table1 [ fk_table2_id ] --> table2 [t2]

First step, DROP old CONSTRAINT: (reference)

ALTER TABLE `table1` 
DROP FOREIGN KEY `fk_name`;  

_{notice constraint is deleted, column is not deleted}

Second step, ADD new CONSTRAINT:

ALTER TABLE `table1`  
ADD CONSTRAINT `fk_name` 
    FOREIGN KEY (`fk_table2_id`) REFERENCES `table2` (`t2`) ON DELETE CASCADE;  

_{adding constraint, column is already there}

Example:

I have a UserDetails table refers to Users table:

mysql> SHOW CREATE TABLE UserDetails;
:
:
 `User_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`Detail_id`),
  KEY `FK_User_id` (`User_id`),
  CONSTRAINT `FK_User_id` FOREIGN KEY (`User_id`) REFERENCES `Users` (`User_id`)
:
:

First step:

mysql> ALTER TABLE `UserDetails` DROP FOREIGN KEY `FK_User_id`;
Query OK, 1 row affected (0.07 sec)  

Second step:

mysql> ALTER TABLE `UserDetails` ADD CONSTRAINT `FK_User_id` 
    -> FOREIGN KEY (`User_id`) REFERENCES `Users` (`User_id`) ON DELETE CASCADE;
Query OK, 1 row affected (0.02 sec)  

result:

mysql> SHOW CREATE TABLE UserDetails;
:
:
`User_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`Detail_id`),
  KEY `FK_User_id` (`User_id`),
  CONSTRAINT `FK_User_id` FOREIGN KEY (`User_id`) REFERENCES 
                                       `Users` (`User_id`) ON DELETE CASCADE
:

Here is a small snippet to demonstrate the date modifications:

$date = date("Y-m-d");
//increment 2 days
$mod_date = strtotime($date."+ 2 days");
echo date("Y-m-d",$mod_date) . "\n";

//decrement 2 days
$mod_date = strtotime($date."- 2 days");
echo date("Y-m-d",$mod_date) . "\n";

//increment 1 month
$mod_date = strtotime($date."+ 1 months");
echo date("Y-m-d",$mod_date) . "\n";

//increment 1 year
$mod_date = strtotime($date."+ 1 years");
echo date("Y-m-d",$mod_date) . "\n";

None of the links above about lib and lib32 folder worked for me with Oracle Client 11.2.0 But I found this on the OTN community:

As far as inspecting a client install to try to tell if it's 32 bit or 64 bit, you can check the registry, a 32 bit home will be located in HKLM>Software>WOW6432Node>Oracle, whereas a 64 bit home will be in HKLM>Software>Oracle.

This script had a nice approach. Converting it to the language of your choice should not be too difficult:

http://plasmasturm.org/log/416/

#!/usr/bin/perl
use strict;
use warnings;

use Encode qw( decode FB_QUIET );

binmode STDIN, ':bytes';
binmode STDOUT, ':encoding(UTF-8)';

my $out;

while ( <> ) {
  $out = '';
  while ( length ) {
    # consume input string up to the first UTF-8 decode error
    $out .= decode( "utf-8", $_, FB_QUIET );
    # consume one character; all octets are valid Latin-1
    $out .= decode( "iso-8859-1", substr( $_, 0, 1 ), FB_QUIET ) if length;
  }
  print $out;
}

);

Think about somebody doing help(yourmodule) at the interactive interpreter's prompt — what do they want to know? (Other methods of extracting and displaying the information are roughly equivalent to help in terms of amount of information). So if you have in x.py:

"""This module does blah blah."""

class Blah(object):
  """This class does blah blah."""

then:

>>> import x; help(x)

shows:

Help on module x:

NAME
    x - This module does blah blah.

FILE
    /tmp/x.py

CLASSES
    __builtin__.object
        Blah

    class Blah(__builtin__.object)
     |  This class does blah blah.
     |  
     |  Data and other attributes defined here:
     |  
     |  __dict__ = <dictproxy object>
     |      dictionary for instance variables (if defined)
     |  
     |  __weakref__ = <attribute '__weakref__' of 'Blah' objects>
     |      list of weak references to the object (if defined)

As you see, the detailed information on the classes (and functions too, though I'm not showing one here) is already included from those components' docstrings; the module's own docstring should describe them very summarily (if at all) and rather concentrate on a concise summary of what the module as a whole can do for you, ideally with some doctested examples (just like functions and classes ideally should have doctested examples in their docstrings).

I don't see how metadata such as author name and copyright / license helps the module's user — it can rather go in comments, since it could help somebody considering whether or not to reuse or modify the module.

These posts helped me get past a couple of issues I had creating a CLR Stored Procedure with Restful API call against Infor M3 API.

The XML Result from these API's look like this for my code below:

Hopefully this provides helpful.

There are only two ways to be 100% certain that the COUNT(*) and the actual query will give consistent results:

• Combined the COUNT(*) with the query, as in your Approach 2. I recommend the form you show in your example, not the correlated subquery form shown in the comment from kogus.
• Use two queries, as in your Approach 1, after starting a transaction in SNAPSHOT or SERIALIZABLE isolation level.

Using one of those isolation levels is important because any other isolation level allows new rows created by other clients to become visible in your current transaction. Read the MSDN documentation on SET TRANSACTION ISOLATION for more details.

You can easily restart your MySql service. This kicks the error off.

To preserve key order, instead of hash(str(dictionary)) or hash(json.dumps(dictionary)) I would prefer quick-and-dirty solution:

from pprint import pformat
h = hash(pformat(dictionary))

It will work even for types like DateTime and more that are not JSON serializable.

• Yes, although it can be tricky to get debugging working, especially if trying to debug SQL on a remote SQL server from your own development machine.
• In the first instance I'd recommend getting this working by debugging directly on the server first, if possible.
• Log to the SQL server using an account that has sysadmin rights, or ask your DBA to to do this.
• Then, for your own Windows account, create a 'login' in SQL Server, if it isn't already there:

• Right-click the account > properties - ensure that the login is a member of the 'sysadmin' role:

• (also ensure that the account is 'owner' of any databases that you want to debug scripts (e.g. stored procs) for:

• Then, login directly onto the SQL server using your Windows account.
• Login to SQL server using Windows Authentication (using the account you've just used to log into the server)
• Now 'Debug' the query in SQL management studio, setting breakpoints as necessary. You can step into stored procs using F11:

• Here's a useful guide to debugging:

• If you need to remotely debug, then once you've got this part working, you can try setting up remote debugging:

You can create a new sorted copy using Java 8 Stream or Guava:

// Java 8 version
List<String> sortedNames = names.stream().sorted().collect(Collectors.toList());
// Guava version
List<String> sortedNames = Ordering.natural().sortedCopy(names); 

Another option is to sort in-place via Collections API:

Collections.sort(names);

I have this problems and fixed, String TAG without space:

"my tag" // noting show
"my_tag" // is ok

Yes this is happening because you are accessing mi variable from within your anonymous inner class, what happens deep inside is that another copy of your variable is created and will be use inside the anonymous inner class, so for data consistency the compiler will try restrict you from changing the value of mi so that's why its telling you to set it to final.

I know it is a bit late to answer this question, but it is the first entry in google, so I think it is worth to answer it.

The problem is not a coding problem, it is an architecture problem.

You have created an interface class Event: public Item to define the methods which all events should implement. Then you have defined two types of events which inherits from class Event: public Item; Arrival and Landing and then, you have added a method Landing* createNewLanding(Arrival* arrival); from the landing functionality in the class Event: public Item interface. You should move this method to the class Landing: public Event class because it only has sense for a landing. class Landing: public Event and class Arrival: public Event class should know class Event: public Item but event should not know class Landing: public Event nor class Arrival: public Event.

I hope this helps, regards, Alberto

You are using growthRate both as a variable name and a function name. The variable hides the function, and then you are trying to use the variable as if it was the function - that is not valid.

Rename the local variable.

Tested in JSFiddle and does what you're asking for.This approach has the added benefit of firing when a label associated with a checkbox is clicked.

Updated Answer:

$(document).ready(function() {
    //set initial state.
    $('#textbox1').val(this.checked);

    $('#checkbox1').change(function() {
        if(this.checked) {
            var returnVal = confirm("Are you sure?");
            $(this).prop("checked", returnVal);
        }
        $('#textbox1').val(this.checked);        
    });
});

Original Answer:

$(document).ready(function() {
    //set initial state.
    $('#textbox1').val($(this).is(':checked'));

    $('#checkbox1').change(function() {
        if($(this).is(":checked")) {
            var returnVal = confirm("Are you sure?");
            $(this).attr("checked", returnVal);
        }
        $('#textbox1').val($(this).is(':checked'));        
    });
});

mcilist = (from mci in mcilist select mci).Distinct().ToList();

If you want them to be displayed side by side, why is sideContent the child of mainContent? make them siblings then use:

float:left; display:inline; width: 49%;

on both of them.

#mainContent, #sideContent {float:left; display:inline; width: 49%;}

bootstrap-4 add class float-left or right for floating

Changed all dependencies to compile rather than implementation, then I rebuild the project without errors. Then I switched back to implementation rather than leaving it as compile.

I will suggest creating a setup project for the reasons while deploying this seems the best convinience , no headaches of copying files manually. Follow the Windows service setup creation tutorial and you know how to create it. And this instance is for vb.net but it is the same for any type.

./script.sh | sort -u

This is the same as monoxide's answer, but a bit more concise.

You can try this:

import subprocess
import sys

process = subprocess.Popen(
    cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE
)

while True:
    out = process.stdout.read(1)
    if out == '' and process.poll() != None:
        break
    if out != '':
        sys.stdout.write(out)
        sys.stdout.flush()

If you use readline instead of read, there will be some cases where the input message is not printed. Try it with a command the requires an inline input and see for yourself.

Please refer to the android developer guide

Layout file was main_activity.xml so the generate class was MainActivityBinding

Since your xml is named "activity_contact_list.xml", you should use ActivityContactListBinding instead of the original one

To summarize the information found after the link: The JVM allocates the amount specified by -Xms but the OS usually does not allocate real pages until they are needed. So the JVM allocates virtual memory as specified by Xms but only allocates physical memory as is needed.

You can see this by using Process Explorer by Sysinternals instead of task manager on windows.

So there is a real difference between using -Xms64M and -Xms512M. But I think the most important difference is the one you already pointed out: the garbage collector will run more often if you really need the 512MB but only started with 64MB.

I'm facing same issue. Solved it using by http:// or https:// in react js.

Another way:

// Generate a simple dataset containing five values and convert int to string type

val df = spark.range(5).select( col("id").cast("string")).withColumnRenamed("id","value")

1. Open 'Maven projects' (tab on the right side).
2. Use 'Add Maven Projects'
3. Find your pom.xml

let my_u8: u8 = "42".parse::<u8>().unwrap();
let my_u32: u32 = "42".parse::<u32>().unwrap();

// or, to be safe, match the `Err`
match "foobar".parse::<i32>() {
  Ok(n) => do_something_with(n),
  Err(e) => weep_and_moan(),
}

str::parse::<u32> returns a Result<u32, core::num::ParseIntError> and Result::unwrap "Unwraps a result, yielding the content of an Ok [or] panics if the value is an Err, with a panic message provided by the Err's value."

str::parse is a generic function, hence the type in angle brackets.

I had multiple copies of same file. Simply, keep one copy and remove all remaining. Clean Build, and issue sorted.

If you want get location of Database you can check Get All DBs Location.
you can use sys.master_files for get location of db and sys.databse to get db name

SELECT
    db.name AS DBName,
    type_desc AS FileType,
    Physical_Name AS Location
FROM
    sys.master_files mf
INNER JOIN 
    sys.databases db ON db.database_id = mf.database_id

I found that I cannot reference System.ComponentModel.DataAnnotations from Silverlight 5 with the below version at (1). I found that Silverlight 5 assemblies cannot use .NET assemblies, it gives the error "You can't add a reference to System.ComponentModel.DataAnnotations as it was not built against the Silverlight runtime. ..." I plan to workaround this by hopefully installing the Silverlight 5 package found at (2) below. If this fails I will update this post.

[UPDATE: it failed. I installed everything relating to Silverlight 5 and I don't have the Silverlight version of the .dll assembly System.ComponentModel.DataAnnotations . Too bad. UPDATE II: I found an old .dll having this name from a previous installation of Silverlight developer's kit for Visual Studio 2008 or 2010. I added this file and it seems to 'work', in that IntelliSense is now recognizing attributes on class members, such as [Display(Name = "My Property Name")]. Whether or not this works for everything else in this .dll I don't know.]

For people still looking a couple of years later, things have changed a bit. You can now use the queue for .fadeIn() as well so that it will work like this:

$('.tooltip').fadeIn({queue: false, duration: 'slow'});
$('.tooltip').animate({ top: "-10px" }, 'slow');

This has the benefit of working on display: none elements so you don't need the extra two lines of code.

The most succinct way to do this is:

Get-WmiObject -Class win32_computersystem -Property *

There is also the approach of organizing the folders not by the structure of the framework, but by the structure of the application's function. There is a github starter Angular/Express application that illustrates this called angular-app.

You want reorder(). Here is an example with dummy data

set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))

require("ggplot2")

p1 <- ggplot(df, aes(x = Category, y = Count)) +
         geom_bar(stat = "identity")

p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
         geom_bar(stat = "identity")

require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))

Giving:

Use reorder(Category, Count) to have Category ordered from low-high.

Very simple to override the method in the fragment:

@Override

public void setUserVisibleHint(boolean isVisibleToUser) {
    super.setUserVisibleHint(isVisibleToUser);

    if(isVisibleToUser){
        actionView();
    }
    else{
        //no
    }      
}

You can use this to get all directories and sub-directories. Then simply loop through to process the files.

string[] folders = System.IO.Directory.GetDirectories(@"C:\My Sample Path\","*", System.IO.SearchOption.AllDirectories);

foreach(string f in folders)
{
   //call some function to get all files in folder
}

Found the problem, need to use function(err,obj) instead:

Auth.findOne({nick: 'noname'}, function(err,obj) { console.log(obj); });

Try this one

Open Visual Studio Code and press Command + Shift + P then type Shell in command palette now you are able to find this option like Shell Command : Install code in PATH from suggested list in command palette. Select that options.

Open VSCode via Terminal/Command Prompt

That's it.

Now open your terminal type.

$ code .

As far I think I understood your question I believe that u can simply declare your variable inside "DECLARE" and then after the "begin" u can use 'select into " you variable" ' statement. the code would look like this:

DECLARE
YourVar  varchar(50);
begin 
select ID into YourVar  from table
where ...

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);

intent.setType("text/csv");

intent.addCategory(Intent.CATEGORY_OPENABLE);

try {
      startActivityForResult(Intent.createChooser(intent, "Select a File to Upload"), 0);

} catch (android.content.ActivityNotFoundException ex) {
  ex.printStackTrace();
}

then you just need to add the response

public void  onActivityResult(int requestCode, int resultCode, Intent data){

switch (requestCode) {
  case 0: {
     //what you want to do
    //file = new File(uri.getPath());
  }
}
}

Here's a solution that also includes High(er)DPI (MDPI) devices > ~160 dots per inch like quite a few non-iOS Devices (f.e.: Google Nexus 7 2012):

.box {
    background: url( 'img/box-bg.png' ) no-repeat top left;
    width: 200px;
    height: 200px;
}
@media only screen and ( -webkit-min-device-pixel-ratio: 1.3 ),
       only screen and (    min--moz-device-pixel-ratio: 1.3 ),
       only screen and (      -o-min-device-pixel-ratio: 2.6/2 ), /* returns 1.3, see Dev.Opera */
       only screen and (         min-device-pixel-ratio: 1.3 ),
       only screen and ( min-resolution: 124.8dpi ),
       only screen and ( min-resolution: 1.3dppx ) {

       .box {
           background: url( 'img/[email protected]' ) no-repeat top left / 200px 200px;
       }

}

As @3rror404 included in his edit after receiving feedback from the comments, there's a world beyond Webkit/iPhone. One thing that bugs me with most solutions around so far like the one referenced as source above at CSS-Tricks, is that this isn't taken fully into account.
The original source went already further.

As an example the Nexus 7 (2012) screen is a TVDPI screen with a weird device-pixel-ratio of 1.325. When loading the images with normal resolution they are upscaled via interpolation and therefore blurry. For me applying this rule in the media query to include those devices succeeded in best customer feedback.

It is also now possible to use OCaml for developing iOS applications. It is not part of the standard distribution and requires modifications provided by the Psellos company. See here for more information: http://psellos.com/ocaml/.

The easiest way use it as array is use vector::data() member.

I feel like there should be a no javascript solution, but how is this?

http://jsfiddle.net/NfmX3/2/

$(window).resize(function() {
    $('#content').height($(window).height() - 46);
});

$(window).trigger('resize');

The first error you're getting - permissions - is the most indicative. Bump wp-content and wp-admin to 777 and try it, and if it works, then change them both back to 755 and see if it still works. What are you using to change folder permissions? An FTP client?

How about the Live method?

$('.add_to_this a').live('click', function() {
    alert('hello from binded function call');
});

Still, what you did about looks like it should work. There's another post that looks pretty similar.

You can do it using heap memory (through malloc() invocation) like other answers reported here, but you must always manage the memory (use free() function everytime you call your function). You can also do it with a static array:

char* returnArrayPointer() 
{
static char array[SIZE];

// do something in your array here

return array; 
}

You can than use it without worrying about memory management.

int main() 
{
char* myArray = returnArrayPointer();
/* use your array here */
/* don't worry to free memory here */
}

In this example you must use static keyword in array definition to set to application-long the array lifetime, so it will not destroyed after return statement. Of course, in this way you occupy SIZE bytes in your memory for the entire application life, so size it properly!

Laravel Eloquent provides destroy() function in which returns boolean value. So if a record exists on the database and deleted you'll get true otherwise false.

Here's an example using Laravel Tinker shell.

In this case, your code should look like this:

public function destroy($id)
    {
        $res = User::destroy($id);
        if ($res) {
            return response()->json([
                'status' => '1',
                'msg' => 'success'
            ]);
        } else {
            return response()->json([
                'status' => '0',
                'msg' => 'fail'
            ]);
        }
    }

In addition to the good answers above to set the navigation view controller on top of your screen on your app, you can add it to your AppDelegate.swift file inside the block as follows

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    window = UIWindow()
    window?.makeKeyAndVisible()
    window?.rootViewController = UINavigationController(rootViewController: LoginViewController())

    return true

}

To give a little more flexibility I would add the next function to my repository:

public function findByNot($field, $value)
{
    $qb = $this->createQueryBuilder('a');
    $qb->where($qb->expr()->not($qb->expr()->eq('a.'.$field, '?1')));
    $qb->setParameter(1, $value);

    return $qb->getQuery()
        ->getResult();
}

Then, I could call it in my controller like this:

$this->getDoctrine()->getRepository('MyBundle:Image')->findByNot('id', 1);

To see the file size of your containers, you can use the --size argument of docker ps:

docker ps --size

Try with:

@NgModule({
  imports: [
      BrowserModule,
      RouterModule.forRoot(appRoutes),
      FormsModule               
  ],
  declarations: [
      AppComponent,  
      DashboardComponent      
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

There is no need to configure the exports in AppModule, because AppModule wont be imported by other modules in your application.

The answer of Mintir4 is fine, I would also do the following to load the file.

FileInputStream fis = myContext.openFileInput(fn);
BufferedReader r = new BufferedReader(new InputStreamReader(fis));
String s = "";

while ((s = r.readLine()) != null) {
    txt += s;
}

r.close();

Your syntax almost works in SQL Server 2008 (but not in SQL Server 2005¹):

CREATE TABLE MyTable (id int, name char(10));

INSERT INTO MyTable (id, name) VALUES (1, 'Bob'), (2, 'Peter'), (3, 'Joe');

SELECT * FROM MyTable;

id |  name
---+---------
1  |  Bob       
2  |  Peter     
3  |  Joe       

¹ When the question was answered, it was not made evident that the question was referring to SQL Server 2005. I am leaving this answer here, since I believe it is still relevant.

Adding to sagiv's answer, we should create the parent component in such a way that it can consist all children components rather than returning the child components in the way you were trying to return.

Try to intentiate the parent component and pass the props inside it so that all children can use it like below

const NewComponent = NewHOC(Movie);

Here NewHOC is the parent component and all its child are going to use movie as props.

But any way, you guyd6 have solved a problem for new react developers as this might be a problem that can come too and here is where they can find the solution for that.

The best way to do this is with the sample function from the random module,

import numpy as np
import pandas as pd
from random import sample

# given data frame df

# create random index
rindex =  np.array(sample(xrange(len(df)), 10))

# get 10 random rows from df
dfr = df.ix[rindex]

You can simple read this way .

List<string> lines = System.IO.File.ReadLines(completePath).ToList();

A proper answer.

HashMap<Integer, Object> map = new HashMap<Integer, Object>();

ArrayList<Integer> sortedKeys = new ArrayList<Integer>(map.keySet());
Collections.sort(sortedKeys, new Comparator<Integer>() {
  @Override
  public int compare(Integer a, Integer b) {
    return a.compareTo(b);
  }
});

for (Integer key: sortedKeys) {
  //map.get(key);
}

Note that HashMap itself cannot maintain sorting, as other answers have pointed out. It's a hash map, and hashed values are unsorted. You can thus either sort the keys when you need to and then access the values in order, as I demonstrated above, or you can find a different collection to store your data, like an ArrayList of Pairs/Tuples, such as the Pair found in Apache Commons:

https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/tuple/Pair.html

$('.Timestamp').datetimepicker({
    format: 'DD/MM/YYYY HH:mm:ss'
});

To skip future dates:

$(function () {
    var date = new Date();
    var currentMonth = date.getMonth();
    var currentDate = date.getDate();
    var currentYear = date.getFullYear();
    $('#datetimepicker,#datetimepicker1').datetimepicker({
        pickTime: false,
        format: "DD-MM-YYYY",  
        maxDate: new Date(currentYear, currentMonth, currentDate + 1)
    });
});

Thank you all for your answers but I figured out how to do it and the final procedure looks like that :

Create Procedure sp_ADD_RESPONSABLE_EXTRANET_CLIENT
(
@ParLngId int output
)
as
Begin
if not exists (Select ParLngId from T_Param where ParStrIndex = 'RES' and ParStrP2 = 'Web')
    Begin
            INSERT INTO T_Param values('RES','¤ExtranetClient', 'ECli', 'Web', 1, 1, Null, Null, 'non', 'ExtranetClient', 'ExtranetClient', 25032, Null, '[email protected]', 'Extranet-Client', Null, 27, Null, Null, Null, Null, Null, Null, Null, Null, 1, Null, Null, 0 )
            SET @ParLngId = @@IDENTITY
    End
Else
    Begin
            SET @ParLngId = (Select top 1 ParLngId from T_Param where ParStrNom = 'Extranet Client')
            Return @ParLngId
    End   
End

So the thing that I found out and which made it works is:

if not exists

It allows us to use a boolean instead of Null or 0 or a number resulted of count()

This works in MySQL all versions and Amazon RDS Aurora:

INSERT INTO my_table SELECT 0,tmp.* FROM tmp;

or

Setting the index column to NULL and then doing the INSERT.

But not in MariaDB, I tested version 10.

Below code will fix root = tk.Tk() to its size before it was called:

root.resizable(False, False)

Bless is a high quality, full featured hex editor.

It is written in mono/Gtk# and its primary platform is GNU/Linux. However it should be able to run without problems on every platform that mono and Gtk# run.

Bless currently provides the following features:

• Efficient editing of large data files and block devices.
• Multilevel undo - redo operations.
• Customizable data views.
• Fast data rendering on screen.
• Multiple tabs.
• Fast find and replace operations.
• A data conversion table.
• Advanced copy/paste capabilities.
• Highlighting of selection pattern matches in the file.
• Plugin based architecture.
• Export of data to text and html (others with plugins).
• Bitwise operations on data.
• A comprehensive user manual.

wxHexEditor is another Free Hex Editor, built because there is no good hex editor for Linux system, specially for big files.

• It uses 64 bit file descriptors (supports files or devices up to 2^64 bytes , means some exabytes but tested only 1 PetaByte file (yet). ).
• It does NOT copy whole file to your RAM. That make it FAST and can open files (which sizes are Multi Giga < Tera < Peta < Exabytes)
• Could open your devices on Linux, Windows or MacOSX.
• Memory Usage : Currently ~10 MegaBytes while opened multiple > ~8GB files.
• Could operate thru XOR encryption.
• Written with C++/wxWidgets GUI libs and can be used with other OSes such as Mac OS, Windows as native application.
• You can copy/edit your Disks, HDD Sectors with it.( Usefull for rescue files/partitions by hand. )
• You can delete/insert bytes to file, more than once, without creating temp file.

DHEX is a more than just another hex editor: It includes a diff mode, which can be used to easily and conveniently compare two binary files. Since it is based on ncurses and is themeable, it can run on any number of systems and scenarios. With its utilization of search logs, it is possible to track changes in different iterations of files easily. Wikipedia article

You can sort on Linux to find some more here: http://en.wikipedia.org/wiki/Comparison_of_hex_editors

If disk 'local' is not working for you then try this :

1. Change local to public in 'default' => env('FILESYSTEM_DRIVER', 'public'), from project_folder/config/filesystem.php
2. Clear config cache php artisan config:clear
3. Then create sym link php artisan storage:link

To get url of uploaded image you can use this Storage::url('iamge_name.jpg');

I had the same problem and I solved it like this:

$text = str_replace("'", "\'", $YourContent);

There is probably a better way to do this, but it worked for me and it should work for you too.
