SHTML is a file extension that lets the web server know the file should be processed as using Server Side Includes (SSI).

(HTML is...you know what it is, and DHTML is Microsoft's name for Javascript+HTML+CSS or something).

You can use SSI to include a common header and footer in your pages, so you don't have to repeat code as much. Changing one included file updates all of your pages at once. You just put it in your HTML page as per normal.

It's embedded in a standard XML comment, and looks like this:

<!--#include virtual="top.shtml" -->

It's been largely superseded by other mechanisms, such as PHP includes, but some hosting packages still support it and nothing else.

You can read more in this Wikipedia article.

Localhost is the computer you're using right now. You run things by typing commands at the command prompt and pressing Enter. If you're asking how to run things from your programming environment, then the answer depends on which environment you're using. Most languages have commands with names like system or exec for running external programs. You need to be more specific about what you're actually looking to do, and what obstacles you've encountered while trying to achieve it.

Gitx is also a fantastic visualization tool if you happen to be on OS X.

Had same problem in Eclipse. Could not Rebase=>abort from Eclipse.

Executing git rebase --abort from Git Bash Worked for me.

No, there is no built-in support for number formatting, but googling will turn up loads of code snippets that will do this for you.

EDIT: I missed the last sentence of your post. Try http://code.google.com/p/jquery-utils/wiki/StringFormat for a jQuery solution.

I use a batch script to compile and run C#:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc /out:%1 %2

@echo off

if errorlevel 1 (
    pause
    exit
)

start %1 %1

I call it like this:

C:\bin\csc.bat "C:\code\MyProgram.exe" "C:\code\MyProgram.cs"

I also have a shortcut in Notepad++, which you can define by going to Run > Run...:

C:\bin\csc.bat "$(CURRENT_DIRECTORY)\$(NAME_PART).exe" "$(FULL_CURRENT_PATH)"

I assigned this shortcut to my F5 key for maximum laziness.

i use concantenate. works for me.

1. fill j2-j14 with '(appostrophe)
2. enter L2 with formula =concantenate(j2,k2)
3. copy L2 to L3-L14

This will resolve your error. Run these commands in your terminal. These commands will add the older versions. You can update them later or you can change version here too before running these commands one by one.

You have two objects both named bank_holiday -- one a list and one a function. Disambiguate the two.

bank_holiday[month] is raising an error because Python thinks bank_holiday refers to the function (the last object bound to the name bank_holiday), whereas you probably intend it to mean the list.

I think Nathan Long's answer is the way to go. For me, I am using client-side validation, so I just added a condition that the form be valid.

EDIT: If this is not added, the user will never be able to submit the form if the client-side validation encounters an error.

        // jQuery plugin to prevent double submission of forms
        jQuery.fn.preventDoubleSubmission = function () {
            $(this).on('submit', function (e) {
                var $form = $(this);

                if ($form.data('submitted') === true) {
                    // Previously submitted - don't submit again
                    alert('Form already submitted. Please wait.');
                    e.preventDefault();
                } else {
                    // Mark it so that the next submit can be ignored
                    // ADDED requirement that form be valid
                    if($form.valid()) {
                        $form.data('submitted', true);
                    }
                }
            });

            // Keep chainability
            return this;
        };

You simply can find a matrix dimension by using Numpy:

import numpy as np

x = np.arange(24).reshape((6, 4))
x.ndim

output will be:

2

It means this matrix is a 2 dimensional matrix.

x.shape

Will show you the size of each dimension. The shape for x is equal to:

(6, 4)

If you don't want to add a wrapper, you could just add the code manually, since you know the ID you are targeting:

var myID = "xxx";

var newCode = "<div id='"+myID+"'>"+$("#"+myID).html()+"</div>";

Simply add the following rules to your td:

overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
// These ones do the trick
width: 100%;
max-width: 0;

Example:

table {_x000D_
  width: 100%_x000D_
}_x000D_
_x000D_
td {_x000D_
  white-space: nowrap;_x000D_
}_x000D_
_x000D_
.td-truncate {_x000D_
  overflow: hidden;_x000D_
  text-overflow: ellipsis;_x000D_
  width: 100%;_x000D_
  max-width: 0;_x000D_
}

<table border="1">_x000D_
  <tr>_x000D_
    <td>content</td>_x000D_
    <td class="td-truncate">long contenttttttt ttttttttt ttttttttttttttttttttttt tttttttttttttttttttttt ttt tttt ttttt ttttttt tttttttttttt ttttttttttttttttttttttttt</td>_x000D_
    <td>other content</td>_x000D_
  </tr>_x000D_
</table>

PS: If you want to set a custom width to another td use property min-width.

You actually might want to check out the interop classes available in C# (e.g. Microsoft.Office.Interop.Excel. You say no OLE (which this isn't), but the interop classes are very easy to use. Check out the C# Documentation here (Interop for Excel starts on page 1072 of the C# PDF).

You might be impressed if you haven't tried them.

Please be warned of Microsoft's stance on this:

Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.

In the link you provided, thats not a loop in sql...

thats a loop in programming language

they are first getting list of all distinct districts, and then for each district executing query again.

If you use this syntax:

<div ng-attr-id="{{ 'object-' + myScopeObject.index }}"></div>

Angular will render something like:

 <div ng-id="object-1"></div>

However this syntax:

<div id="{{ 'object-' + $index }}"></div>

will generate something like:

<div id="object-1"></div>

I had the same problem. Here are the steps for Windows 10 users.

Open CMD: win+r then type cmd. Now,

1. Type pip install virtualenv
2. Create a Virtual Environment, Type virtualenv testopencv
3. Get Inside testopencv, Type cd testopencv
4. Activate the Virtual Environment, Type .\Scripts\activate
5. Now Install Opencv, Type pip install opencv-contrib-python --upgrade
6. Let's test Opencv, Type Python then import cv2 hit enter then type print(cv2.__version__) to check if its installed

Now, open a new cmd, win + r then type cmd, repeat step 6. If it gives you an error.

Go inside the testopencv folder, inside lib. Copy everything, go to your python directory, inside lib folder paste it and skip that are already present.

Again open a new cmd, repeat Step 6.

Hope it helps.

A lot of people, including me, use sqlfiddle.com to test SQL.

Others Answers Are Correct But for More Detail check this Post Pull to Refresh

Enable refreshing in Storyboard

When you’re working with a UITableViewController, the solution is fairly simple: First, Select the table view controller in your storyboard, open the attributes inspector, and enable refreshing:

A UITableViewController comes outfitted with a reference to a UIRefreshControl out of the box. You simply need to wire up a few things to initiate and complete the refresh when the user pulls down.

Override viewDidLoad()

In your override of viewDidLoad(), add a target to handle the refresh as follows:

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
        
    self.refreshControl?.addTarget(self, action: "handleRefresh:", forControlEvents: UIControlEvents.ValueChanged)
}

1. Since I’ve specified “handleRefresh:” (note the colon!) as the action argument, I need to define a function in this UITableViewController class with the same name. Additionally, the function should take one argument
2. We’d like this action to be called for the UIControlEvent called ValueChanged
3. Don't forget to call refreshControl.endRefreshing()

While iterating over a JSON array (org.json.JSONArray, built into Android), watch out for null objects; for example, you may get "null" instead of a null string.

A check may look like:

s[i] = array.isNull(i) ? null : array.getString(i);

if you use your website in the same network as the server IE likes to switch to compability mode despite DOCTYPE.
Adding meta http-equiv="X-UA-Compatible" content="IE=Edge" disables this unwanted behaviour.

Add a reference to System.Windows.Form.DataVisualization, then add the appropriate using statement:

using System.Windows.Forms.DataVisualization.Charting;

private void CreateChart()
{
    var series = new Series("Finance");

    // Frist parameter is X-Axis and Second is Collection of Y- Axis
    series.Points.DataBindXY(new[] { 2001, 2002, 2003, 2004 }, new[] { 100, 200, 90, 150 });
    chart1.Series.Add(series);

}

XHTML 1.x forms only support GET and POST. GET and POST are the only allowed values for the "method" attribute.

The answer varies depending on what storage engine you're using. The ideal scenario is if you're using InnoDB. In that case you can use the --single-transaction flag, which will give you a coherent snapshot of the database at the time that the dump begins.

This is a small example that will convert 'image.png' to 'image.jpg' at 70% image quality:

<?php
$image = imagecreatefrompng('image.png');
imagejpeg($image, 'image.jpg', 70);
imagedestroy($image);
?>

Hope that helps

You can use stepi or nexti (which can be abbreviated to si or ni) to step through your machine code.

All three define the meaning of zero in different context.

• pointer context - NULL is used and means the value of the pointer is 0, independent of whether it is 32bit or 64bit (one case 4 bytes the other 8 bytes of zeroes).
• string context - the character representing the digit zero has a hex value of 0x30, whereas the NUL character has hex value of 0x00 (used for terminating strings).

These three are always different when you look at the memory:

NULL - 0x00000000 or 0x00000000'00000000 (32 vs 64 bit)
NUL - 0x00 or 0x0000 (ascii vs 2byte unicode)
'0' - 0x20

I hope this clarifies it.

Had the exact same error in a procedure. It turns out the user running it (a technical user in our case) did not have sufficient rigths to create a temporary table.

EXEC sp_addrolemember 'db_ddladmin', 'username_here';

did the trick

The 'c' means it's a character device. tty is a special file representing the 'controlling terminal' for the current process.

Character Devices

Unix supports 'device files', which aren't really files at all, but file-like access points to hardware devices. A 'character' device is one which is interfaced byte-by-byte (as opposed to buffered IO).

TTY

/dev/tty is a special file, representing the terminal for the current process. So, when you echo 1 > /dev/tty, your message ('1') will appear on your screen. Likewise, when you cat /dev/tty, your subsequent input gets duplicated (until you press Ctrl-C).

/dev/tty doesn't 'contain' anything as such, but you can read from it and write to it (for what it's worth). I can't think of a good use for it, but there are similar files which are very useful for simple IO operations (e.g. /dev/ttyS0 is normally your serial port)

This quote is from http://tldp.org/HOWTO/Text-Terminal-HOWTO-7.html#ss7.3 :

/dev/tty stands for the controlling terminal (if any) for the current process. To find out which tty's are attached to which processes use the "ps -a" command at the shell prompt (command line). Look at the "tty" column. For the shell process you're in, /dev/tty is the terminal you are now using. Type "tty" at the shell prompt to see what it is (see manual pg. tty(1)). /dev/tty is something like a link to the actually terminal device name with some additional features for C-programmers: see the manual page tty(4).

Here is the man page: http://linux.die.net/man/4/tty

A litle bit complete answer is here with all ready for use:

    $sql = "SELECT `username` FROM `users` WHERE `id` = :id";
    $q = $dbh->prepare($sql);
    $q->execute(array(':id' => "4"));
    $done= $q->fetch();

 echo $done[0];

Here $dbh is PDO db connecter, and based on id from table users we've get the username using fetch();

I hope this help someone, Enjoy!

The accepted answer is correct in all means and I stumbled upon this thread after I couldn't get the Google Map render in one of my app components.

Now, if you are on a recent angular version i.e. 7+ of angular then you will have to deal with the following ViewChild declaration i.e.

@ViewChild(selector: string | Function | Type<any>, opts: {
read?: any;
static: boolean;
})

Now, the interesting part is the static value, which by definition says

• static - True to resolve query results before change detection runs

Now for rendering a map, I used the following ,

@ViewChild('map', { static: true }) mapElement: any;
  map: google.maps.Map;

Here's the correct answer, extracted from comments by Daniel Rikowski and pseidemann. I'm tired of having to weed through comments to find the right answer...

If you use Rails (ActiveSupport):

result.class.name.demodulize

If you use POR (plain-ol-Ruby):

result.class.name.split('::').last

When the form is processed, you redirect to another page:

... process complete....
header('Location: thankyou.php');

you can also redirect to the same page.

if you are doing something like comments and you want the user to stay on the same page, you can use Ajax to handle the form submission

Normal array can serve as a dictionary data structure. In general it has multipurpose usage: array, list (vector), hash table, dictionary, collection, stack, queue etc.

$names = [
    'bob' => 27,
    'billy' => 43,
    'sam' => 76,
];

$names['bob'];

And because of wide design it gains no full benefits of specific data structure. You can implement your own dictionary by extending an ArrayObject or you can use SplObjectStorage class which is map (dictionary) implementation allowing objects to be assigned as keys.

Our system architecture often uses the Unity IoC framework to create instances of ClientBase so there's no sure way to enforce that the other developers even use using{} blocks. In order to make it as fool-proof as possible, I made this custom class that extends ClientBase, and handles closing down the channel on dispose, or on finalize in case someone doesn't explicitly dispose of the Unity created instance.

There is also stuff that needed to be done in the constructor to set up the channel for custom credentials and stuff, so that's in here too...

public abstract class PFServer2ServerClientBase<TChannel> : ClientBase<TChannel>, IDisposable where TChannel : class
{
    private bool disposed = false;

    public PFServer2ServerClientBase()
    {
        // Copy information from custom identity into credentials, and other channel setup...
    }

    ~PFServer2ServerClientBase()
    {
        this.Dispose(false);
    }

    void IDisposable.Dispose()
    {
        this.Dispose(true);
        GC.SuppressFinalize(this);
    }

    public void Dispose(bool disposing)
    {
        if (!this.disposed)
        {
            try
            {
                    if (this.State == CommunicationState.Opened)
                        this.Close();
            }
            finally
            {
                if (this.State == CommunicationState.Faulted)
                    this.Abort();
            }
            this.disposed = true;
        }
    }
}

Then a client can simply:

internal class TestClient : PFServer2ServerClientBase<ITest>, ITest
{
    public string TestMethod(int value)
    {
        return base.Channel.TestMethod(value);
    }
}

And the caller can do any of these:

public SomeClass
{
    [Dependency]
    public ITest test { get; set; }

    // Not the best, but should still work due to finalizer.
    public string Method1(int value)
    {
        return this.test.TestMethod(value);
    }

    // The good way to do it
    public string Method2(int value)
    {
        using(ITest t = unityContainer.Resolve<ITest>())
        {
            return t.TestMethod(value);
        }
    }
}

Here's another fun solution. This takes advantage of the locals() dict of a comprehension, i.e. local variables generated inside the list comprehension scope:

>>> [locals().setdefault(i, (elem + locals().get(i-1, 0))) for i, elem 
     in enumerate(time_interval)]
[4, 10, 22]

Here's what the locals() looks for each iteration:

>>> [[locals().setdefault(i, (elem + locals().get(i-1, 0))), locals().copy()][1] 
     for i, elem in enumerate(time_interval)]
[{'.0': <enumerate at 0x21f21f7fc80>, 'i': 0, 'elem': 4, 0: 4},
 {'.0': <enumerate at 0x21f21f7fc80>, 'i': 1, 'elem': 6, 0: 4, 1: 10},
 {'.0': <enumerate at 0x21f21f7fc80>, 'i': 2, 'elem': 12, 0: 4, 1: 10, 2: 22}]

Performance is not terrible for small lists:

>>> %timeit list(accumulate([4, 6, 12]))
387 ns ± 7.53 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

>>> %timeit np.cumsum([4, 6, 12])
5.31 µs ± 67.8 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

>>> %timeit [locals().setdefault(i, (e + locals().get(i-1,0))) for i,e in enumerate(time_interval)]
1.57 µs ± 12 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

And obviously falls flat for larger lists.

>>> l = list(range(1_000_000))
>>> %timeit list(accumulate(l))
95.1 ms ± 5.22 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

>>> %timeit np.cumsum(l)
79.3 ms ± 1.07 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

>>> %timeit np.cumsum(l).tolist()
120 ms ± 1.23 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

>>> %timeit [locals().setdefault(i, (e + locals().get(i-1, 0))) for i, e in enumerate(l)]
660 ms ± 5.14 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

Even though the method is ugly and not practical, it sure is fun.

You can strip strings in Bash alone:

$ foo="Here is a String"
$ foo=${foo##*Here }
$ echo "$foo"
is a String
$ foo=${foo%% String*}
$ echo "$foo"
is a
$

And if you have a GNU grep that includes PCRE, you can use a zero-width assertion:

$ echo "Here is a String" | grep -Po '(?<=(Here )).*(?= String)'
is a

Do something like:

var result = Int32.Parse(str);

Just wanted to share this for web developers:

security-guide-for-developers
https://github.com/FallibleInc/security-guide-for-developers

Vinsa almost had it right you should add

<base href="{{URL::asset('/')}}" target="_top">

and scripts should go in their regular path

<script src="js/jquery/jquery-1.11.1.min.js"></script>

the reason for this is because Images and other things with relative path like image source or ajax requests won't work correctly without the base path attached.

See: http://predef.sourceforge.net/index.php

This project provides a reasonably comprehensive listing of pre-defined #defines for many operating systems, compilers, language and platform standards, and standard libraries.

Who says your main class is in a file on a local harddisk? Classes are more often bundled inside JAR files, and sometimes loaded over the network or even generated on the fly.

So what is it that you actually want to do? There is probably a way to do it that does not make assumptions about where classes come from.

Sorry for the delay. I was with the same problem and I found a link with good answers, could that will help new guys

Basically, there are four situations: using differents verbs, using routing, overload marking with [NoAction] attribute and change the action attribute name with [ActionName]

So, depends that's your requiriments and your situation.

Howsoever, follow the link:

Link: http://www.binaryintellect.net/articles/8f9d9a8f-7abf-4df6-be8a-9895882ab562.aspx

In nodeJS you can you use the "this" special keyword within the setInterval function.

You can use this this keyword to clearInterval, and here is an example:

setInterval(
    function clear() {
            clearInterval(this) 
       return clear;
    }()
, 1000)

When you print the value of this special keyword within the function you outpout a Timeout object Timeout {...}

All cookies are client and server

There is no difference. A regular cookie can be set server side or client side. The 'classic' cookie will be sent back with each request. A cookie that is set by the server, will be sent to the client in a response. The server only sends the cookie when it is explicitly set or changed, while the client sends the cookie on each request.

But essentially it's the same cookie.

But, behavior can change

A cookie is basically a name=value pair, but after the value can be a bunch of semi-colon separated attributes that affect the behavior of the cookie if it is so implemented by the client (or server). Those attributes can be about lifetime, context and various security settings.

HTTP-only (is not server-only)

One of those attributes can be set by a server to indicate that it's an HTTP-only cookie. This means that the cookie is still sent back and forth, but it won't be available in JavaScript. Do note, though, that the cookie is still there! It's only a built in protection in the browser, but if somebody would use a ridiculously old browser like IE5, or some custom client, they can actually read the cookie!

So it seems like there are 'server cookies', but there are actually not. Those cookies are still sent to the client. On the client there is no way to prevent a cookie from being sent to the server.

Alternatives to achieve 'only-ness'

If you want to store a value only on the server, or only on the client, then you'd need some other kind of storage, like a file or database on the server, or Local Storage on the client.

How about disabled=disabled:

<input id="price_from" value="price from " disabled="disabled">????????????

Problem is if you don't want user to edit them, why display them in input? You can hide them even if you want to submit a form. And to display information, just use other tag instead.

(note: this is answer to original version of the question, which did not have requirements for "default")

You can ask it to be pretty.

db.collection.find().pretty()

As David and Remou pointed out, vbCrLf if you want a carriage-return-linefeed combination. Otherwise, Chr(13) and Chr(10) (although some VB-derivatives have vbCr and vbLf; VBScript may well have those, worth checking before using Chr).

split was updated in coreutils release 8.8 (announced 22 Dec 2010) with the --number option to generate a specific number of files. The option --number=l/n generates n files without splitting lines.

It's quite easy to roll back just a specific migration.
Since the command php artisan migrate:rollback, undo the last database migration, and the order of the migrations execution is stored in the batch field in the migrations table.

You can edit the batch value of the migration that you want to rollback and set it as the higher. Then you can rollback that migration with a simple:

php artisan migrate:rollback

After editing the same migration you can execute it again with a simple

php artisan migrate

NOTICE: if two or more migrations have the same higher value, they will be all rolled back at the same time.

If you don't care about vertex reuse, you could have two output files--one for vertices and one for triangles. Then append the triangle file to the vertex file when you are done.

Dennis answer is correct. However I would like to explain the solution in a bit more detailed way (for Windows User):

1. Go into your Start Menu and type regedit into the search field.
2. Navigate to path HKEY_LOCAL_MACHINE\Software\JavaSoft (Windows 10 seems to now have this here: HKEY_LOCAL_MACHINE\Software\WOW6432Node\JavaSoft)
3. Right click on the JavaSoft folder and click on New -> Key
4. Name the new Key Prefs and everything should work.

Alternatively, save and execute a *.reg file with the following content:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs]

Around 1:51 in the video, notice how she puts a <script> tag in there? The way it works is like this:

Create an html file (that's just a text file with a .html ending) somewhere on your computer. In the same folder that you put index.html, put a javascript file (that's just a textfile with a .js ending - let's call it game.js). Then, in your index.html file, put some html that includes the script tag with game.js, like Mary did in the video. index.html should look something like this:

<html>
    <head>
        <script src="game.js"></script>
    </head>
</html>

Now, double click on that file in finder, and it should open it up in your browser. To open up the console to see the output of your javascript code, hit Command-alt-j (those three buttons at the same time).

Good luck on your journey, hope it's as fun for you as it has been for me so far :)

You can print the request type using:

request.getMethod();

You can print all the headers as mentioned here:

Enumeration<String> headerNames = request.getHeaderNames();
while(headerNames.hasMoreElements()) {
  String headerName = headerNames.nextElement();
  System.out.println("Header Name - " + headerName + ", Value - " + request.getHeader(headerName));
}

To print all the request params, use this:

Enumeration<String> params = request.getParameterNames(); 
while(params.hasMoreElements()){
 String paramName = params.nextElement();
 System.out.println("Parameter Name - "+paramName+", Value - "+request.getParameter(paramName));
}

request is the instance of HttpServletRequest

You can beautify the outputs as you desire.

I'd use the Continue statement instead:

For Each I As Item In Items

    If I = x Then
        Continue For
    End If

    ' Do something

Next

Note that this is slightly different to moving the iterator itself on - anything before the If will be executed again. Usually this is what you want, but if not you'll have to use GetEnumerator() and then MoveNext()/Current explicitly rather than using a For Each loop.

Don't overlook the preservation of white space. If you want to process 'fred flinstone' and you get 'Fred Flinstone' instead of 'Fred Flinstone', you've corrupted your white space. Some of the above solutions will lose white space. Here's a solution that's good for Python 2 and 3 and preserves white space.

def propercase(s):
    return ''.join(map(''.capitalize, re.split(r'(\s+)', s)))

Use extern keyword in another .c file.

enumerations accessing is very simple in switch case

private TYPE currentView;

//declaration of enum 
public enum TYPE {
        FIRST, SECOND, THIRD
    };

//handling in switch case
switch (getCurrentView())
        {
        case FIRST:
            break;
        case SECOND:
            break;
        case THIRD:
            break;
        }

//getter and setter of the enum
public void setCurrentView(TYPE currentView) {
        this.currentView = currentView;
    }

    public TYPE getCurrentView() {
        return currentView;
    }

//usage of setting the enum 
setCurrentView(TYPE.FIRST);

avoid the accessing of TYPE.FIRST.ordinal() it is not recommended always

This problem is "best" solved by using an anonymous function to pass-in the jQuery object thusly:

The Anonymous Function Looks Like:

<script type="text/javascript">
    (function($) {
        // You pass-in jQuery and then alias it with the $-sign
        // So your internal code doesn't change
    })(jQuery);
</script>

This is JavaScript's method of implementing (poor man's) 'Dependency Injection' when used alongside things like the 'Module Pattern'.

So Your Code Would Look Like:
Of course, you might want to make some changes to your internal code now, but you get the idea.

<script type="text/javascript">
    (function($) {
        $.fn.pluginbutton = function(options) {
            myoptions = $.extend({ left: true });
            return this.each(function() {
                var focus = false;
                if (focus === false) {
                    this.hover(function() {
                        this.animate({ backgroundPosition: "0 -30px" }, { duration: 0 });
                        this.removeClass('VBfocus').addClass('VBHover');
                    }, function() {
                        this.animate({ backgroundPosition: "0 0" }, { duration: 0 });
                        this.removeClass('VBfocus').removeClass('VBHover');
                    });
                }
                this.mousedown(function() {
                    focus = true
                    this.animate({ backgroundPosition: "0 30px" }, { duration: 0 });
                    this.addClass('VBfocus').removeClass('VBHover');
                }, function() {
                    focus = false;
                    this.animate({ backgroundPosition: "0 0" }, { duration: 0 });
                    this.removeClass('VBfocus').addClass('VBHover');
                });
            });
        }
    })(jQuery);
</script>

Python 2.x:

print '-' * 3

Python 3.x:

print('-' * 3)

  var ctx = document.getElementById('pie-chart').getContext('2d');
 var myPieChart = new Chart(ctx, {
                // The type of chart we want to create
                type: 'pie',

            });

             //define click event
  $("#pie-chart").click(
            function (evt) {
                var activePoints = myPieChart.getElementsAtEvent(evt);
                var labeltag = activePoints[0]._view.label;

                      });

Based on SFEley's answer, here is an updated/fixed one for newer Rails versions:

class SetDefault < ActiveRecord::Migration
  def change
    change_column :table_name, :column_name, :type, default: "Your value"
  end
end

In my case, I've got the same error message and then figured out that I've missed to add csrf_token for the form field. Then add the csrf_token.

Using form helper that will be,

{{ csrf_field() }}

Or without form helper that will be,

<input type="hidden" name="_token" value="{{ csrf_token() }}">

If that doesn't work, then-

Refresh the browser cache

and now it might work, thanks.

Update For Laravel 5.6

Laravel integrates new @csrf instead of {{ csrf_field() }}. That looks more nice now.

<form action="">
   @csrf
   ...
</form>

If you use C++11, you can use the specifier "override", and it will give you a compiler error if your aren't correctly overriding an abstract method. You probably have a method that doesn't match exactly with an abstract method in the base class, so your aren't actually overriding it.

http://en.cppreference.com/w/cpp/language/override

This match 6 or more any chars but newline:

/^.{6,}$/

Here's some sample code that does it.

#include <string.h>
#include <stdlib.h>

char * replace(
    char const * const original, 
    char const * const pattern, 
    char const * const replacement
) {
  size_t const replen = strlen(replacement);
  size_t const patlen = strlen(pattern);
  size_t const orilen = strlen(original);

  size_t patcnt = 0;
  const char * oriptr;
  const char * patloc;

  // find how many times the pattern occurs in the original string
  for (oriptr = original; patloc = strstr(oriptr, pattern); oriptr = patloc + patlen)
  {
    patcnt++;
  }

  {
    // allocate memory for the new string
    size_t const retlen = orilen + patcnt * (replen - patlen);
    char * const returned = (char *) malloc( sizeof(char) * (retlen + 1) );

    if (returned != NULL)
    {
      // copy the original string, 
      // replacing all the instances of the pattern
      char * retptr = returned;
      for (oriptr = original; patloc = strstr(oriptr, pattern); oriptr = patloc + patlen)
      {
        size_t const skplen = patloc - oriptr;
        // copy the section until the occurence of the pattern
        strncpy(retptr, oriptr, skplen);
        retptr += skplen;
        // copy the replacement 
        strncpy(retptr, replacement, replen);
        retptr += replen;
      }
      // copy the rest of the string.
      strcpy(retptr, oriptr);
    }
    return returned;
  }
}

#include <stdio.h>
int main(int argc, char * argv[])
{
  if (argc != 4)
  {
    fprintf(stderr,"usage: %s <original text> <pattern> <replacement>\n", argv[0]);
    exit(-1);
  }
  else
  {
    char * const newstr = replace(argv[1], argv[2], argv[3]);
    if (newstr)
    {
      printf("%s\n", newstr);
      free(newstr);
    }
    else
    {
      fprintf(stderr,"allocation error\n");
      exit(-2);
    }
  }
  return 0;
}

The -i option is the one that you want:

curl -i http://localhost

-i, --include Include protocol headers in the output (H/F)

Alternatively you can use the verbose option:

curl -v http://localhost

-v, --verbose Make the operation more talkative

You can use the usual Python package structure to divide your App into multiple modules, see the Flask docs.

However,

Flask uses a concept of blueprints for making application components and supporting common patterns within an application or across applications.

You can create a sub-component of your app as a Blueprint in a separate file:

simple_page = Blueprint('simple_page', __name__, template_folder='templates')
@simple_page.route('/<page>')
def show(page):
    # stuff

And then use it in the main part:

from yourapplication.simple_page import simple_page

app = Flask(__name__)
app.register_blueprint(simple_page)

Blueprints can also bundle specific resources: templates or static files. Please refer to the Flask docs for all the details.

Try following steps:

1. Type ipconfig (or ifconfig on Linux) at command prompt. This will give you the IP address of your own machine. For example, your machine's IP address is 192.168.1.6. So your broadcast IP address is 192.168.1.255.
2. Ping your broadcast IP address ping 192.168.1.255 (may require -b on Linux)
3. Now type arp -a. You will get the list of all IP addresses on your segment.

if you want, you can use a saveActions plugin. You can reformat file, optimized the imports and more things, it's really customizable and easy to setup.

Bookmarking this URL should give you a full-screen compose window, without any distractions:

https://mail.google.com/mail/?view=cm&fs=1&tf=1

Additionally, if you want to be future-proof (see for instance how other URLs in this question stopped working) you can bookmark a link to:

mailto:

It will open your default email client and you probably already have Gmail configured for that purpose.

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to id.co.bni.switcherservice.model.SwitcherServiceSource

Problem is

(List<SwitcherServiceSource>) LoadSource.list();

This will return a List of Object arrays (Object[]) with scalar values for each column in the SwitcherServiceSource table. Hibernate will use ResultSetMetadata to deduce the actual order and types of the returned scalar values.

Solution

List<Object> result = (List<Object>) LoadSource.list(); 
Iterator itr = result.iterator();
while(itr.hasNext()){
   Object[] obj = (Object[]) itr.next();
   //now you have one array of Object for each row
   String client = String.valueOf(obj[0]); // don't know the type of column CLIENT assuming String 
   Integer service = Integer.parseInt(String.valueOf(obj[1])); //SERVICE assumed as int
   //same way for all obj[2], obj[3], obj[4]
}

Update (2017): The following two libraries have now become the most common drop-down libraries used with Javascript. While they are jQuery-native, they have been customized to work with everything from AngularJS 1.x to having custom CSS for Bootstrap. (Chosen JS, the original answer here, seems to have dropped to #3 in popularity.)

Selectize:

Original answer (2012): I think that the Chosen library might also be useful. Its available in jQuery, Prototype and MooTools versions.

Attached is a screenshot of how the multi-select functionality looks in Chosen.

If you want to use hex codes, you should add -e option to enable interpretation of backslash escapes by echo (but the result is the same as with echoCtrlRCtrlB). And as wallyk said, you probably want to add -n to prevent the output of a newline:

echo -en '\x12\x02' > /dev/ttyS0

Also make sure that /dev/ttyS0 is the port you want.

Solution:

wget -r -np -nH --cut-dirs=3 -R index.html http://hostname/aaa/bbb/ccc/ddd/

Explanation:

• It will download all files and subfolders in ddd directory
• -r : recursively
• -np : not going to upper directories, like ccc/…
• -nH : not saving files to hostname folder
• --cut-dirs=3 : but saving it to ddd by omitting first 3 folders aaa, bbb, ccc
• -R index.html : excluding index.html files

I liked qiao's first answer very much! The only thing missing here is to mark the vertexes as visited.

Why we need to do it?
Lets imagine that there is another node number 13 connected from node 11. Now our goal is to find node 13.
After a little bit of a run the queue will look like this:

[[1, 2, 6], [1, 3, 10], [1, 4, 7], [1, 4, 8], [1, 2, 5, 9], [1, 2, 5, 10]]

Note that there are TWO paths with node number 10 at the end.
Which means that the paths from node number 10 will be checked twice. In this case it doesn't look so bad because node number 10 doesn't have any children.. But it could be really bad (even here we will check that node twice for no reason..)
Node number 13 isn't in those paths so the program won't return before reaching to the second path with node number 10 at the end..And we will recheck it..

All we are missing is a set to mark the visited nodes and not to check them again..
This is qiao's code after the modification:

graph = {
    1: [2, 3, 4],
    2: [5, 6],
    3: [10],
    4: [7, 8],
    5: [9, 10],
    7: [11, 12],
    11: [13]
}


def bfs(graph_to_search, start, end):
    queue = [[start]]
    visited = set()

    while queue:
        # Gets the first path in the queue
        path = queue.pop(0)

        # Gets the last node in the path
        vertex = path[-1]

        # Checks if we got to the end
        if vertex == end:
            return path
        # We check if the current node is already in the visited nodes set in order not to recheck it
        elif vertex not in visited:
            # enumerate all adjacent nodes, construct a new path and push it into the queue
            for current_neighbour in graph_to_search.get(vertex, []):
                new_path = list(path)
                new_path.append(current_neighbour)
                queue.append(new_path)

            # Mark the vertex as visited
            visited.add(vertex)


print bfs(graph, 1, 13)

The output of the program will be:

[1, 4, 7, 11, 13]

Without the unneccecery rechecks..

Put the default rowHeight in viewDidLoad or awakeFromNib. As pointed out by Martin R., you cannot call cellForRowAtIndexPath from heightForRowAtIndexPath

self.tableView.rowHeight = 44.0

The problem is that readlines is a list of strings, each of which is a line of filename. Perhaps you meant:

for line in readlines:
    Type = line.split(",")
    x = Type[1]
    y = Type[2]
    print(x,y)

Postgresql historically doesn't support procedural code at the command level - only within functions. However, in Postgresql 9, support has been added to execute an inline code block that effectively supports something like this, although the syntax is perhaps a bit odd, and there are many restrictions compared to what you can do with SQL Server. Notably, the inline code block can't return a result set, so can't be used for what you outline above.

In general, if you want to write some procedural code and have it return a result, you need to put it inside a function. For example:

CREATE OR REPLACE FUNCTION somefuncname() RETURNS int LANGUAGE plpgsql AS $$
DECLARE
  one int;
  two int;
BEGIN
  one := 1;
  two := 2;
  RETURN one + two;
END
$$;
SELECT somefuncname();

The PostgreSQL wire protocol doesn't, as far as I know, allow for things like a command returning multiple result sets. So you can't simply map T-SQL batches or stored procedures to PostgreSQL functions.

One more possible cause is this:

If you attempt to set the button's title in the (id)initWithNibName: ... method, then you're button property will still be nil. It hasn't yet been assigned to the UIButton.

You must be sure that you're setting your buttons in a method like (void)viewWillLoad or (void)viewWillAppear, but you probably don't want to set them as late as (void)viewDidAppear.

If you feel like using Rxjs:

var element = document;_x000D_
_x000D_
Rx.Observable_x000D_
  .merge(_x000D_
    Rx.Observable.fromEvent(element, 'mousedown').mapTo(0),_x000D_
    Rx.Observable.fromEvent(element, 'mousemove').mapTo(1)_x000D_
  )_x000D_
  .sample(Rx.Observable.fromEvent(element, 'mouseup'))_x000D_
  .subscribe(flag => {_x000D_
      console.clear();_x000D_
      console.log(flag ? "drag" : "click");_x000D_
  });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<script src="https://unpkg.com/@reactivex/[email protected]/dist/global/Rx.js"></script>

This is a direct clone of what @wong2 did in his answer, but converted to RxJs.

Also interesting use of sample. The sample operator will take the latest value from the source (the merge of mousedown and mousemove) and emit it when the inner observable (mouseup) emits.

Why to complicate the scenario? Its very simple and straight forward

1. Convert list to set - removes duplicates
2. Convert set to list again - which gives list in ascending order

Here is a code

mlist = [2, 3, 6, 6, 5]
mlist = list(set(mlist))
print mlist[-2]

In 3.1 you just get rid of the 'images' part of the path. So an image that lives in /assets/images/example.png will actually be accessible in a get request at this url - /assets/example.png

Because the assets/images folder gets generated along with a new 3.1 app, this is the convention that they probably want you to follow. I think that's where image_tag will look for it, but I haven't tested that yet.

Also, during the RailsConf keynote, I remember D2h saying the the public folder should not have much in it anymore, mostly just error pages and a favicon.

You can use two different techniques to achieve this.

The first one is with javascript: set the scrollTop property of the scrollable element (e.g. document.body.scrollTop = 1000;).

The second is setting the link to point to a specific id in the page e.g.

<a href="mypage.html#sectionOne">section one</a>

Then if in your target page you'll have that ID the page will be scrolled automatically.

Time Zone

To format an Instant a time-zone is required. Without a time-zone, the formatter does not know how to convert the instant to human date-time fields, and therefore throws an exception.

The time-zone can be added directly to the formatter using withZone().

DateTimeFormatter formatter =
    DateTimeFormatter.ofLocalizedDateTime( FormatStyle.SHORT )
                     .withLocale( Locale.UK )
                     .withZone( ZoneId.systemDefault() );

If you specifically want an ISO-8601 format with no explicit time-zone (as the OP asked), with the time-zone implicitly UTC, you need

DateTimeFormatter.ISO_LOCAL_DATE_TIME.withZone(ZoneId.from(ZoneOffset.UTC))

Generating String

Now use that formatter to generate the String representation of your Instant.

Instant instant = Instant.now();
String output = formatter.format( instant );

Dump to console.

System.out.println("formatter: " + formatter + " with zone: " + formatter.getZone() + " and Locale: " + formatter.getLocale() );
System.out.println("instant: " + instant );
System.out.println("output: " + output );

When run.

formatter: Localized(SHORT,SHORT) with zone: US/Pacific and Locale: en_GB
instant: 2015-06-02T21:34:33.616Z
output: 02/06/15 14:34

The most efficient is to create a buffer of the correct size and then read the file into the buffer.

#include <fstream>
#include <vector>

int main()
{
    std::ifstream       file("Plop");
    if (file)
    {
        /*
         * Get the size of the file
         */
        file.seekg(0,std::ios::end);
        std::streampos          length = file.tellg();
        file.seekg(0,std::ios::beg);

        /*
         * Use a vector as the buffer.
         * It is exception safe and will be tidied up correctly.
         * This constructor creates a buffer of the correct length.
         * Because char is a POD data type it is not initialized.
         *
         * Then read the whole file into the buffer.
         */
        std::vector<char>       buffer(length);
        file.read(&buffer[0],length);
    }
}

The solution to the problem for me was looking in my install directory, finding the /data folder, and copying it's content to the data folder that was specified in my .ini/.cnf configuration file.

response_filtering

All REST APIs accept a filter_path parameter that can be used to reduce the response returned by elasticsearch. This parameter takes a comma separated list of filters expressed with the dot notation.

https://stackoverflow.com/a/35647027/844700

This issue was resolved thanks to this guide: https://help.ubuntu.com/community/ApacheMySQLPHP#Troubleshooting_Phpmyadmin_.26_mysql-workbench by adding

Include /etc/phpmyadmin/apache.conf

...to the /etc/apache2/apache2.conf file and restarting the service.

I am also new to MVC and I received the same error and found that it is not passing proper routeValues in the Index view or whatever view is present to view the all data.

It was as below

<td>
            @Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
        </td>

I changed it to the as show below and started to work properly.

<td>
            @Html.ActionLink("Edit", "Edit", new { EmployeeID=item.EmployeeID }) |
            @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
        </td>

Basically this error can also come because of improper navigation also.

Partial classes make it possible to add functionality to a suitably-designed program merely by adding source files. For example, a file-import program could be designed so that one could add different types of known files by adding modules that handle them. For example, the main file type converter could include a small class:

Partial Public Class zzFileConverterRegistrar
    Event Register(ByVal mainConverter as zzFileConverter)
    Sub registerAll(ByVal mainConverter as zzFileConverter)
        RaiseEvent Register(mainConverter)
    End Sub
End Class

Each module that wishes to register one or more types of file converter could include something like:

Partial Public Class zzFileConverterRegistrar
    Private Sub RegisterGif(ByVal mainConverter as zzFileConverter) Handles Me.Register
        mainConverter.RegisterConverter("GIF", GifConverter.NewFactory))
    End Sub
End Class

Note that the main file converter class isn't "exposed"--it just exposes a little stub class that add-in modules can hook to. There is a slight risk of naming conflicts, but if each add-in module's "register" routine is named according to the type of file it deals with, they probably shouldn't pose a problem. One could stick a GUID in the name of the registration subroutine if one were worried about such things.

Edit/Addendum To be clear, the purpose of this is to provide a means by which a variety of separate classes can let a main program or class know about them. The only thing the main file converter will do with zzFileConverterRegistrar is create one instance of it and call the registerAll method which will fire the Register event. Any module that wants to hook that event can execute arbitrary code in response to it (that's the whole idea) but there isn't anything a module could do by improperly extending the zzFileConverterRegistrar class other than define a method whose name matches that of something else. It would certainly be possible for one improperly-written extension to break another improperly-written extension, but the solution for that is for anyone who doesn't want his extension broken to simply write it properly.

One could, without using partial classes, have a bit of code somewhere within the main file converter class, which looked like:

  RegisterConverter("GIF", GifConvertor.NewFactory)
  RegisterConverter("BMP", BmpConvertor.NewFactory)
  RegisterConverter("JPEG", JpegConvertor.NewFactory)

but adding another converter module would require going into that part of the converter code and adding the new converter to the list. Using partial methods, that is no longer necessary--all converters will get included automatically.

When I stumbled up on this answer I was looking for a way to get an output that is easy to parse. For me the option --with-colons did the trick:

$ gpg --with-colons file
sec::4096:1:AAAAAAAAAAAAAAAA:YYYY-MM-DD::::Name (comment) email
ssb::4096:1:BBBBBBBBBBBBBBBB:YYYY-MM-DD::::

Documentation can be found here.

You also can send in mutable objects as parameters, if you use methods to modify them then they will be modified when you return from the function. It won't work on stuff like Float, since it is immutable.

     public static void main(String []args){
        HelloWorld world = new HelloWorld();

        world.run();
     }



    private class Dog
    {
       private String name;
       public void setName(String s)
       {
           name = s;
       }
       public String getName() { return name;}
       public Dog(String name)
       {
           setName(name);
       }
    }

    public void run()
    {
       Dog newDog = new Dog("John");
       nameThatDog(newDog);
       System.out.println(newDog.getName());
     }


     public void nameThatDog(Dog dog)
     {
         dog.setName("Rutger");
     }
}

The result is: Rutger

Sometimes you need to call the base class' implementation, when you aren't in the derived function...It still works:

struct Base
{
    virtual int Foo()
    {
        return -1;
    }
};

struct Derived : public Base
{
    virtual int Foo()
    {
        return -2;
    }
};

int main(int argc, char* argv[])
{
    Base *x = new Derived;

    ASSERT(-2 == x->Foo());

    //syntax is trippy but it works
    ASSERT(-1 == x->Base::Foo());

    return 0;
}

You can check file xib is same name with your file class. Default XCode will get name xib file from name file class, so if their names are different, XCode can't detect from storyboard It's work with me

JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm page.

One idea is to let the the browser know that it should redirect by adding a redirect variable to to the resulting object and checking for it in JQuery:

$(document).ready(function(){ 
    jQuery.ajax({ 
        type: "GET", 
        url: "populateData.htm", 
        dataType:"json", 
        data:"userId=SampleUser", 
        success:function(response){ 
            if (response.redirect) {
                window.location.href = response.redirect;
            }
            else {
                // Process the expected results...
            }
        }, 
     error: function(xhr, textStatus, errorThrown) { 
            alert('Error!  Status = ' + xhr.status); 
         } 

    }); 
}); 

You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1") and in JQuery you do on success(!):

//....
        success:function(response){ 
            if (response.getResponseHeader('REQUIRES_AUTH') === '1'){ 
                window.location.href = 'login.htm'; 
            }
            else {
                // Process the expected results...
            }
        }
//....

Hope that helps.

My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.

Below is corrected Snippet of runThread Function.

private void runThread() {

    new Thread() {
        public void run() {
            while (i++ < 1000) {
                try {
                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                            btn.setText("#" + i);
                        }
                    });
                    Thread.sleep(300);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }.start();
}

Maybe just:

  margin: auto 0 auto auto;

You wrote """I assume that means the HTML contains some wrongly-formed attempt at unicode somewhere."""

The HTML is NOT expected to contain any kind of "attempt at unicode", well-formed or not. It must of necessity contain Unicode characters encoded in some encoding, which is usually supplied up front ... look for "charset".

You appear to be assuming that the charset is UTF-8 ... on what grounds? The "\xA0" byte that is shown in your error message indicates that you may have a single-byte charset e.g. cp1252.

If you can't get any sense out of the declaration at the start of the HTML, try using chardet to find out what the likely encoding is.

Why have you tagged your question with "regex"?

Update after you replaced your whole question with a non-question:

html = urllib.urlopen(link).read()
# html refers to a str object. To get unicode, you need to find out
# how it is encoded, and decode it.

html.encode("utf8","ignore")
# problem 1: will fail because html is a str object;
# encode works on unicode objects so Python tries to decode it using 
# 'ascii' and fails
# problem 2: even if it worked, the result will be ignored; it doesn't 
# update html in situ, it returns a function result.
# problem 3: "ignore" with UTF-n: any valid unicode object 
# should be encodable in UTF-n; error implies end of the world,
# don't try to ignore it. Don't just whack in "ignore" willy-nilly,
# put it in only with a comment explaining your very cogent reasons for doing so.
# "ignore" with most other encodings: error implies that you are mistaken
# in your choice of encoding -- same advice as for UTF-n :-)
# "ignore" with decode latin1 aka iso-8859-1: error implies end of the world.
# Irrespective of error or not, you are probably mistaken
# (needing e.g. cp1252 or even cp850 instead) ;-)

During recent experience writing a JS interpreter I wrestled plenty with the inner workings of ECMA/JS dates. So, I figure I'll throw in my 2 cents here. Hopefully sharing this stuff will help others with any questions about the differences among browsers in how they handle dates.

The Input Side

All implementations store their date values internally as 64-bit numbers that represent the number of milliseconds (ms) since 1970-01-01 UTC (GMT is the same thing as UTC). This date is the ECMAScript epoch that is also used by other languages such as Java and POSIX systems such as UNIX. Dates occurring after the epoch are positive numbers and dates prior are negative.

The following code is interpreted as the same date in all current browsers, but with the local timezone offset:

Date.parse('1/1/1970'); // 1 January, 1970

In my timezone (EST, which is -05:00), the result is 18000000 because that's how many ms are in 5 hours (it's only 4 hours during daylight savings months). The value will be different in different time zones. This behaviour is specified in ECMA-262 so all browsers do it the same way.

While there is some variance in the input string formats that the major browsers will parse as dates, they essentially interpret them the same as far as time zones and daylight saving is concerned even though parsing is largely implementation dependent.

However, the ISO 8601 format is different. It's one of only two formats outlined in ECMAScript 2015 (ed 6) specifically that must be parsed the same way by all implementations (the other is the format specified for Date.prototype.toString).

But, even for ISO 8601 format strings, some implementations get it wrong. Here is a comparison output of Chrome and Firefox when this answer was originally written for 1/1/1970 (the epoch) on my machine using ISO 8601 format strings that should be parsed to exactly the same value in all implementations:

Date.parse('1970-01-01T00:00:00Z');       // Chrome: 0         FF: 0
Date.parse('1970-01-01T00:00:00-0500');   // Chrome: 18000000  FF: 18000000
Date.parse('1970-01-01T00:00:00');        // Chrome: 0         FF: 18000000

• In the first case, the "Z" specifier indicates that the input is in UTC time so is not offset from the epoch and the result is 0
• In the second case, the "-0500" specifier indicates that the input is in GMT-05:00 and both browsers interpret the input as being in the -05:00 timezone. That means that the UTC value is offset from the epoch, which means adding 18000000ms to the date's internal time value.
• The third case, where there is no specifier, should be treated as local for the host system. FF correctly treats the input as local time while Chrome treats it as UTC, so producing different time values. For me this creates a 5 hour difference in the stored value, which is problematic. Other systems with different offsets will get different results.

This difference has been fixed as of 2020, but other quirks exist between browsers when parsing ISO 8601 format strings.

But it gets worse. A quirk of ECMA-262 is that the ISO 8601 date–only format (YYYY-MM-DD) is required to be parsed as UTC, whereas ISO 8601 requires it to be parsed as local. Here is the output from FF with the long and short ISO date formats with no time zone specifier.

Date.parse('1970-01-01T00:00:00');       // 18000000
Date.parse('1970-01-01');                // 0

So the first is parsed as local because it's ISO 8601 date and time with no timezone, and the second is parsed as UTC because it's ISO 8601 date only.

So, to answer the original question directly, "YYYY-MM-DD" is required by ECMA-262 to be interpreted as UTC, while the other is interpreted as local. That's why:

This doesn't produce equivalent results:

console.log(new Date(Date.parse("Jul 8, 2005")).toString()); // Local
console.log(new Date(Date.parse("2005-07-08")).toString());  // UTC

This does:

console.log(new Date(Date.parse("Jul 8, 2005")).toString());
console.log(new Date(Date.parse("2005-07-08T00:00:00")).toString());

The bottom line is this for parsing date strings. The ONLY ISO 8601 string that you can safely parse across browsers is the long form with an offset (either ±HH:mm or "Z"). If you do that you can safely go back and forth between local and UTC time.

This works across browsers (after IE9):

console.log(new Date(Date.parse("2005-07-08T00:00:00Z")).toString());

Most current browsers do treat the other input formats equally, including the frequently used '1/1/1970' (M/D/YYYY) and '1/1/1970 00:00:00 AM' (M/D/YYYY hh:mm:ss ap) formats. All of the following formats (except the last) are treated as local time input in all browsers. The output of this code is the same in all browsers in my timezone. The last one is treated as -05:00 regardless of the host timezone because the offset is set in the timestamp:

console.log(Date.parse("1/1/1970"));
console.log(Date.parse("1/1/1970 12:00:00 AM"));
console.log(Date.parse("Thu Jan 01 1970"));
console.log(Date.parse("Thu Jan 01 1970 00:00:00"));
console.log(Date.parse("Thu Jan 01 1970 00:00:00 GMT-0500"));

However, since parsing of even the formats specified in ECMA-262 is not consistent, it is recommended to never rely on the built–in parser and to always manually parse strings, say using a library and provide the format to the parser.

E.g. in moment.js you might write:

let m = moment('1/1/1970', 'M/D/YYYY'); 

The Output Side

On the output side, all browsers translate time zones the same way but they handle the string formats differently. Here are the toString functions and what they output. Notice the toUTCString and toISOString functions output 5:00 AM on my machine. Also, the timezone name may be an abbreviation and may be different in different implementations.

Converts from UTC to Local time before printing

 - toString
 - toDateString
 - toTimeString
 - toLocaleString
 - toLocaleDateString
 - toLocaleTimeString

Prints the stored UTC time directly

 - toUTCString
 - toISOString 

In Chrome

toString            Thu Jan 01 1970 00:00:00 GMT-05:00 (Eastern Standard Time)
toDateString        Thu Jan 01 1970
toTimeString        00:00:00 GMT-05:00 (Eastern Standard Time)
toLocaleString      1/1/1970 12:00:00 AM
toLocaleDateString  1/1/1970
toLocaleTimeString  00:00:00 AM

toUTCString         Thu, 01 Jan 1970 05:00:00 GMT
toISOString         1970-01-01T05:00:00.000Z

In Firefox

toString            Thu Jan 01 1970 00:00:00 GMT-05:00 (Eastern Standard Time)
toDateString        Thu Jan 01 1970
toTimeString        00:00:00 GMT-0500 (Eastern Standard Time)
toLocaleString      Thursday, January 01, 1970 12:00:00 AM
toLocaleDateString  Thursday, January 01, 1970
toLocaleTimeString  12:00:00 AM

toUTCString         Thu, 01 Jan 1970 05:00:00 GMT
toISOString         1970-01-01T05:00:00.000Z

I normally don't use the ISO format for string input. The only time that using that format is beneficial to me is when dates need to be sorted as strings. The ISO format is sortable as-is while the others are not. If you have to have cross-browser compatibility, either specify the timezone or use a compatible string format.

The code new Date('12/4/2013').toString() goes through the following internal pseudo-transformation:

  "12/4/2013" -> toUCT -> [storage] -> toLocal -> print "12/4/2013"

IIS 6.0 and previous versions :

ASP.NET integrated with IIS via an ISAPI extension, a C API ( C Programming language based API ) and exposed its own application and request processing model.

This effectively exposed two separate server( request / response ) pipelines, one for native ISAPI filters and extension components, and another for managed application components. ASP.NET components would execute entirely inside the ASP.NET ISAPI extension bubble AND ONLY for requests mapped to ASP.NET in the IIS script map configuration.

Requests to non ASP.NET content types:- images, text files, HTML pages, and script-less ASP pages, were processed by IIS or other ISAPI extensions and were NOT visible to ASP.NET.

The major limitation of this model was that services provided by ASP.NET modules and custom ASP.NET application code were NOT available to non ASP.NET requests

What's a SCRIPT MAP ?

Script maps are used to associate file extensions with the ISAPI handler that executes when that file type is requested. The script map also has an optional setting that verifies that the physical file associated with the request exists before allowing the request to be processed

A good example can be seen here

IIS 7 and above

IIS 7.0 and above have been re-engineered from the ground up to provide a brand new C++ API based ISAPI.

IIS 7.0 and above integrates the ASP.NET runtime with the core functionality of the Web Server, providing a unified(single) request processing pipeline that is exposed to both native and managed components known as modules ( IHttpModules )

What this means is that IIS 7 processes requests that arrive for any content type, with both NON ASP.NET Modules / native IIS modules and ASP.NET modules providing request processing in all stages This is the reason why NON ASP.NET content types (.html, static files ) can be handled by .NET modules.

• You can build new managed modules (IHttpModule) that have the ability to execute for all application content, and provided an enhanced set of request processing services to your application.
• Add new managed Handlers ( IHttpHandler)

After digging a bit through the perlre docs a bit, I'll present my best suggestion so far that seems to work pretty good. Perl 5.10 added the \R character class as a generalized linebreak:

$line =~ s/\R//g;

It's the same as:

(?>\x0D\x0A?|[\x0A-\x0C\x85\x{2028}\x{2029}])

I'll keep this question open a while yet, just to see if there's more nifty ways waiting to be suggested.

Take caution not to overuse the section tag as a replacement for a div element. A section tag should define a significant region within the context of the body. Semantically, HTML5 encourages us to define our document as follows:

<html>_x000D_
<head></head>_x000D_
<body>_x000D_
    <header></header>_x000D_
    <section>_x000D_
        <h1></h1>_x000D_
        <div>_x000D_
            <span></span>_x000D_
        </div>_x000D_
        <div></div>_x000D_
    </section>_x000D_
    <footer></footer>_x000D_
</body>_x000D_
</html>

This strategy allows web robots and automated screen readers to better understand the flow of your content. This markup clearly defines where your major page content is contained. Of course, headers and footers are often common across hundreds if not thousands of pages within a website. The section tag should be limited to explain where the unique content is contained. Within the section tag, we should then continue to markup and control the content with HTML tags which are lower in the hierarchy, like h1, div, span, etc.

In most simple pages, there should only be a single section tag, not multiple ones. Please also consider also that there are other interesting HTML5 tags which are similar to section. Consider using article, summary, aside and others within your document flow. As you can see, these tags further enhance our ability to define the major regions of the HTML document.

As gratitude to the timely help I got from here - a minor update to above.

$query = "UPDATE `db`.`table` SET `fieldname`=  str_to_date(  fieldname, '%d/%m/%Y')";

1. this.setState({ abc.xyz: 'new value' }); syntax is not allowed. You have to pass the whole object.

   this.setState({abc: {xyz: 'new value'}});
   

   If you have other variables in abc

   var abc = this.state.abc;
   abc.xyz = 'new value';
   this.setState({abc: abc});
   

2. You can have ordinary variables, if they don't rely on this.props and this.state.

If you are using the script approach and have an error concerning the LDF and MDF files, you can first query the the backup file for the logical names (and other details) of files in the backup set, using the following:

-- Queries the backup file for the file list in backup set, where Type denotes 
-- type of file. Can be L,D,F or S
-- info: https://docs.microsoft.com/en-us/sql/t-sql/statements/restore-statements-filelistonly-transact-sql
RESTORE FILELISTONLY FROM DISK = 'C:\Temp\DB_backup.bak'
GO

You will get results similar to the following:

And then you can use those logical names in the queries:

    -- Script assumes you want MDF and LDF files restored on separate drives. Modify for your scenario
    RESTORE DATABASE DB 
    FROM DISK='C:\Temp\DB_backup.bak'
    WITH REPLACE,
      MOVE 'DB' TO 'E:\MSSQL\Data\DB.mdf', -- "DB" is the mdf logical name from query above
      MOVE 'DB_log' TO 'F:\MSSQL\Logs\DB.ldf'; -- "DB_log" is LDF logical name from query above

More info on RESTORE FILELISTONLY can be found from the SQL Server docs.

try this one out.

<label for="user">user</label>
<input type="text" name="user" 
onfocus="if(this.value==this.defaultValue)this.value=''"    
onblur="if(this.value=='')this.value=this.defaultValue" 
value="username" maxlength="19" />

hope this helps.

If by autostart you mean auto start on phone bootup then you should register a BroadcastReceiver for the BOOT_COMPLETED Intent. Android systems broadcasts that intent once boot is completed.

Once you receive that intent you can launch a Service that can do whatever you want to do.

Keep note though that having a Service running all the time on the phone is generally a bad idea as it eats up system resources even when it is idle. You should launch your Service / application only when needed and then stop it when not required.

(Python3) This is what worked for me. If you just use the \010 then it will leave characters, so I tweaked it a bit to make sure it's overwriting what was there. This also allows you to have something before the first print item and only removed the length of the item.

print("Here are some strings: ", end="")
items = ["abcd", "abcdef", "defqrs", "lmnop", "xyz"]
for item in items:
    print(item, end="")
    for i in range(len(item)): # only moving back the length of the item
        print("\010 \010", end="") # the trick!
        time.sleep(0.2) # so you can see what it's doing

Regexp work on the character base, and \d means a single digit 0...9 and not a decimal number.

A regular expression that matches only integers with a sign could be for example

^[-+]?[0-9]+$

meaning

1. ^ - start of string
2. [-+]? - an optional (this is what ? means) minus or plus sign
3. [0-9]+ - one or more digits (the plus means "one or more" and [0-9] is another way to say \d)
4. $ - end of string

Note: having the sign considered part of the number is ok only if you need to parse just the number. For more general parsers handling expressions it's better to leave the sign out of the number: source streams like 3-2 could otherwise end up being parsed as a sequence of two integers instead of an integer, an operator and another integer. My experience is that negative numbers are better handled by constant folding of the unary negation operator at an higher level.

With the newest API, here's the code I used for it

You can add atom beauty package for formatting text in atom..

file --> setting --> Install

then you type atom-beautify in search area.

then click Package button.. select atom beuty and install it.

next you can format your text using (Alt + ctrl + b) or right click and select beautify editor contents

This is the answer

Little bit off topic but say i want to remove all 2s from a list. Here's a very elegant way to do that.

void RemoveAll<T>(T item,List<T> list)
{
    while(list.Contains(item)) list.Remove(item);
}

With predicate:

void RemoveAll<T>(Func<T,bool> predicate,List<T> list)
{
    while(list.Any(predicate)) list.Remove(list.First(predicate));
}

+1 only to encourage you to leave your answer here for learning purposes. You're also right about it being off-topic, but I won't ding you for that because of there is significant value in leaving your examples here, again, strictly for learning purposes. I'm posting this response as an edit because posting it as a series of comments would be unruly.

Though your examples are short & compact, neither is elegant in terms of efficiency; the first is bad at O(n²), the second, absolutely abysmal at O(n³). Algorithmic efficiency of O(n²) is bad and should be avoided whenever possible, especially in general-purpose code; efficiency of O(n³) is horrible and should be avoided in all cases except when you know n will always be very small. Some might fling out their "premature optimization is the root of all evil" battle axes, but they do so naïvely because they do not truly understand the consequences of quadratic growth since they've never coded algorithms that have to process large datasets. As a result, their small-dataset-handling algorithms just run generally slower than they could, and they have no idea that they could run faster. The difference between an efficient algorithm and an inefficient algorithm is often subtle, but the performance difference can be dramatic. The key to understanding the performance of your algorithm is to understand the performance characteristics of the primitives you choose to use.

In your first example, list.Contains() and Remove() are both O(n), so a while() loop with one in the predicate & the other in the body is O(n²); well, technically O(m*n), but it approaches O(n²) as the number of elements being removed (m) approaches the length of the list (n).

Your second example is even worse: O(n³), because for every time you call Remove(), you also call First(predicate), which is also O(n). Think about it: Any(predicate) loops over the list looking for any element for which predicate() returns true. Once it finds the first such element, it returns true. In the body of the while() loop, you then call list.First(predicate) which loops over the list a second time looking for the same element that had already been found by list.Any(predicate). Once First() has found it, it returns that element which is passed to list.Remove(), which loops over the list a third time to yet once again find that same element that was previously found by Any() and First(), in order to finally remove it. Once removed, the whole process starts over at the beginning with a slightly shorter list, doing all the looping over and over and over again starting at the beginning every time until finally no more elements matching the predicate remain. So the performance of your second example is O(m*m*n), or O(n³) as m approaches n.

Your best bet for removing all items from a list that match some predicate is to use the generic list's own List<T>.RemoveAll(predicate) method, which is O(n) as long as your predicate is O(1). A for() loop technique that passes over the list only once, calling list.RemoveAt() for each element to be removed, may seem to be O(n) since it appears to pass over the loop only once. Such a solution is more efficient than your first example, but only by a constant factor, which in terms of algorithmic efficiency is negligible. Even a for() loop implementation is O(m*n) since each call to Remove() is O(n). Since the for() loop itself is O(n), and it calls Remove() m times, the for() loop's growth is O(n²) as m approaches n.

First you need to publish the file by:

1. BUILD -> PUBLISH or by right clicking project on Solution Explorer -> properties -> publish or select project in Solution Explorer and press Alt + Enter NOTE: if you are using Visual Studio 2013 then in properties you have to go to BUILD and then you have to disable define DEBUG constant and define TRACE constant and you are ready to go.

2. Save your file to a particular folder. Find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the bin\Debug folder below the project file (.csproj). In Visual Studio they are in the Application Files folder and inside that you just need the .exe and dll files. (You have to delete ClickOnce and other files and then make this folder a zip file and distribute it.)

NOTE: The ClickOnce application does install the project to system, but it has one advantage. You DO NOT require administrative privileges here to run (if your application follows the normal guidelines for which folders to use for application data, etc.).

What I do for abstract classes and interfaces is the following: I write a test, that uses the object as it is concrete. But the variable of type X (X is the abstract class) is not set in the test. This test-class is not added to the test-suite, but subclasses of it, that have a setup-method that set the variable to a concrete implementation of X. That way I don't duplicate the test-code. The subclasses of the not used test can add more test-methods if needed.

in my webpack.config.js (Version 1,2,3) file, I have

function isExternal(module) {
  var context = module.context;

  if (typeof context !== 'string') {
    return false;
  }

  return context.indexOf('node_modules') !== -1;
}

in my plugins array

plugins: [
  new CommonsChunkPlugin({
    name: 'vendors',
    minChunks: function(module) {
      return isExternal(module);
    }
  }),
  // Other plugins
]

Now I have a file that only adds 3rd party libs to one file as required.

If you want get more granular where you separate your vendors and entry point files:

plugins: [
  new CommonsChunkPlugin({
    name: 'common',
    minChunks: function(module, count) {
      return !isExternal(module) && count >= 2; // adjustable
    }
  }),
  new CommonsChunkPlugin({
    name: 'vendors',
    chunks: ['common'],
    // or if you have an key value object for your entries
    // chunks: Object.keys(entry).concat('common')
    minChunks: function(module) {
      return isExternal(module);
    }
  })
]

Note that the order of the plugins matters a lot.

Also, this is going to change in version 4. When that's official, I update this answer.

Update: indexOf search change for windows users

A slightly more complete example of scope:

from __future__ import print_function  # for python 2 support

x = 100
print("1. Global x:", x)
class Test(object):
    y = x
    print("2. Enclosed y:", y)
    x = x + 1
    print("3. Enclosed x:", x)

    def method(self):
        print("4. Enclosed self.x", self.x)
        print("5. Global x", x)
        try:
            print(y)
        except NameError as e:
            print("6.", e)

    def method_local_ref(self):
        try:
            print(x)
        except UnboundLocalError as e:
            print("7.", e)
        x = 200 # causing 7 because has same name
        print("8. Local x", x)

inst = Test()
inst.method()
inst.method_local_ref()

output:

1. Global x: 100
2. Enclosed y: 100
3. Enclosed x: 101
4. Enclosed self.x 101
5. Global x 100
6. global name 'y' is not defined
7. local variable 'x' referenced before assignment
8. Local x 200

here is my code for the same problem someone can also try this. jquery

<script>
$(document).ready(function(){`
$(".check11").change(function(){
var favorite1 = [];        
$.each($("input[name='check1']:checked"), function(){                    
favorite1.push($(this).val());
document.getElementById("countch1").innerHTML=favorite1;
});
});
});
</script>

Andrew Bullock solution works just fine, I just wanted to show you mine and add a warning.

//Works great

$('#<%= radBuffetCapacity.ClientID %> input').click(function (e) {
   var val = $('#<%= radBuffetCapacity.ClientID %>').find('input:checked').val();
   //Do whatever
});

//Warning - works in firefox but not IE8 .. used this for some time before a noticing that it didnt work in IE8... used to everything working in all browsers with jQuery when working in one.

$('#<%= radBuffetCapacity.ClientID %>').change(function (e) {
   var val = $('#<%= radBuffetCapacity.ClientID %>').find('input:checked').val();
   //Do whatever
});

Destination Host Unreachable

This message indicates one of two problems: either the local system has no route to the desired destination, or a remote router reports that it has no route to the destination.

If the message is simply "Destination Host Unreachable," then there is no route from the local system, and the packets to be sent were never put on the wire.

If the message is "Reply From < IP address >: Destination Host Unreachable," then the routing problem occurred at a remote router, whose address is indicated by the "< IP address >" field.

Request Timed Out

This message indicates that no Echo Reply messages were received within the default time of 1 second. This can be due to many different causes; the most common include network congestion, failure of the ARP request, packet filtering, routing error, or a silent discard.

Great example from Strawberry Perl's portable shell launcher:

set drive=%~dp0
set drivep=%drive%
if #%drive:~-1%# == #\# set drivep=%drive:~0,-1%

set PATH=%drivep%\perl\site\bin;%drivep%\perl\bin;%drivep%\c\bin;%PATH%

not sure what the negative 1's doing there myself, but it works a treat!

To solve this issue, put these two lines in your index.html page.

<script>var exports = {"__esModule": true};</script>
<script type="text/javascript" src="/main.js">

Make sure to check your main.js file path.

This is the correct answer:

<input type="number" step="0.01" min="-9999999999.99" max="9999999999.99"/>

Simple answer:A grammar is said to be an LL(1),if the associated LL(1) parsing table has atmost one production in each table entry.

Take the simple grammar A -->Aa|b.[A is non-terminal & a,b are terminals]
   then find the First and follow sets A.
    First{A}={b}.
    Follow{A}={$,a}.

    Parsing table for Our grammar.Terminals as columns and Nonterminal S as a row element.

        a            b                   $
    --------------------------------------------
 S  |               A-->a                      |
    |               A-->Aa.                    |
    -------------------------------------------- 

As [S,b] contains two Productions there is a confusion as to which rule to choose.So it is not LL(1).

Some simple checks to see whether a grammar is LL(1) or not. Check 1: The Grammar should not be left Recursive. Example: E --> E+T. is not LL(1) because it is Left recursive. Check 2: The Grammar should be Left Factored.

Left factoring is required when two or more grammar rule choices share a common prefix string. Example: S-->A+int|A.

Check 3:The Grammar should not be ambiguous.

These are some simple checks.

It's implementation-specific, but in practice the rule (in the absence of #pragma pack or the like) is:

• Struct members are stored in the order they are declared. (This is required by the C99 standard, as mentioned here earlier.)
• If necessary, padding is added before each struct member, to ensure correct alignment.
• Each primitive type T requires an alignment of sizeof(T) bytes.

So, given the following struct:

struct ST
{
   char ch1;
   short s;
   char ch2;
   long long ll;
   int i;
};

• ch1 is at offset 0
• a padding byte is inserted to align...
• s at offset 2
• ch2 is at offset 4, immediately after s
• 3 padding bytes are inserted to align...
• ll at offset 8
• i is at offset 16, right after ll
• 4 padding bytes are added at the end so that the overall struct is a multiple of 8 bytes. I checked this on a 64-bit system: 32-bit systems may allow structs to have 4-byte alignment.

So sizeof(ST) is 24.

It can be reduced to 16 bytes by rearranging the members to avoid padding:

struct ST
{
   long long ll; // @ 0
   int i;        // @ 8
   short s;      // @ 12
   char ch1;     // @ 14
   char ch2;     // @ 15
} ST;

Have a try with this:

setVolumeControlStream(AudioManager.STREAM_MUSIC);

According to the official documentation on sitemaps.org it needs to be a full URL:

You can specify the location of the Sitemap using a robots.txt file. To do this, simply add the following line including the full URL to the sitemap:

Sitemap: http://www.example.com/sitemap.xml

The environmental variable ANDROID_AVD_HOME can be used to define the directory in which the AVD Manager shall look for AVD INI files and can therefore be used to change the location of the virtual devices;

The default value is %USERPROFILE%\.android\avd on Windows (or ~/.android/avd on Linux).

One can also create a link for the whole directory %USERPROFILE%\.android on Windows (or a sym-link for directory ~/.android on Linux).

When moving AVDs, the path entry in AVD INI file needs to be updated accordingly.

I wrote an article on topis how to [manually install curl on debian linu][1]x.

[1]: http://www.jasom.net/how-to-install-curl-command-manually-on-debian-linux. This is its shortcut:

1. cd /usr/local/src
2. wget http://curl.haxx.se/download/curl-7.36.0.tar.gz
3. tar -xvzf curl-7.36.0.tar.gz
4. rm *.gz
5. cd curl-7.6.0
6. ./configure
7. make
8. make install

And restart Apache. If you will have an error during point 6, try to run apt-get install build-essential.

Based in the response of basarat, I give here a little more information how to run this in Visual Studio 2013.

• Go to Windows Start button -> All Programs -> Visual Studio 2013 -> Visual Studio Tools A windows is open with a list of tool.

• Select Developer Command Prompt for VS2013
• In the opened Console write: tsc -v
• You get the version: See Image

[UPDATE]

If you update your Visual Studio to a new version of Typescript as 1.0.x you don't see the last version here. To see the last version:

• Go to: C:\Program Files (x86)\Microsoft SDKs\TypeScript, there you see directories of type 0.9, 1.0 1.1
• Enter the high number that you have (in this case 1.1)
• Copy the directory and run in CMD the command tsc -v, you get the version.

NOTE: Typescript 1.3 install in directory 1.1, for that it is important to run the command to know the last version that you have installed.

NOTE: It is possible that you have installed a version 1.3 and your code use 1.0.3. To avoid this if you have your Typescript in a separate(s) project(s) unload the project and see if the Typescript tag:

<TypeScriptToolsVersion>1.1</TypeScriptToolsVersion> 

is set to 1.1.

[UPDATE 2]

TypeScript version 1.4, 1.5 .. 1.7 install in 1.4, 1.5... 1.7 directories. they are not problem to found version. if you have typescript in separate project and you migrate from a previous typescript your project continue to use the old version. to solve this:

unload the project file and change the typescript version to 1.x at:

  <TypeScriptToolsVersion>1.x</TypeScriptToolsVersion>

If you installed the typescript using the visual studio installer file, the path to the new typescript compiler should be automatically updated to point to 1.x directory. If you have problem, review that you environment variable Path include

C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.x\

SUGGESTION TO MICROSOFT :-) Because Typescript run side by side with other version, maybe is good to have in the project properties have a combo box to select the typescript compiler (similar to select the net version)

//go through this code I have made several changes in it//

import java.util.Scanner;

public class addContact {

String [] contactAdd2 = new String [12];
int i=0;
String name = "0";
String phone = "0";
String add1 = "0";
String add2 = "0";
//method of taken input
Scanner input = new Scanner(System.in);

//while name field is empty display prompt etc.
while (i<11)

    i++;
System.out.println("Enter contacts name: "+ i);
name = input.nextLine();
name += contactName[i];
}


while (i<12)
{
    i++;
System.out.println("Enter contacts addressline1:");
add1 = input.nextLine();
add1 += contactAdd1[i];
}

while (i<12)
{
    i++;
System.out.println("Enter contacts addressline2:");
add2 = input.nextLine();
add2 += contactAdd2[i];
}

while (i<12)
{
    i++;
System.out.println("Enter contact phone number: ");
phone = input.nextLine();
phone += contactPhone[i];
}

}   
}

Try to use:
easy_install lxml
That works for me, win10, python 2.7.

wget -nd -r -l 2 -A jpg,jpeg,png,gif http://t.co

• -nd: no directories (save all files to the current directory; -P directory changes the target directory)
• -r -l 2: recursive level 2
• -A: accepted extensions

wget -nd -H -p -A jpg,jpeg,png,gif -e robots=off example.tumblr.com/page/{1..2}

• -H: span hosts (wget doesn't download files from different domains or subdomains by default)
• -p: page requisites (includes resources like images on each page)
• -e robots=off: execute command robotos=off as if it was part of .wgetrc file. This turns off the robot exclusion which means you ignore robots.txt and the robot meta tags (you should know the implications this comes with, take care).

Example: Get all .jpg files from an exemplary directory listing:

$ wget -nd -r -l 1 -A jpg http://example.com/listing/

To describe model I use following snippet

Model.columns.collect { |c| "#{c.name} (#{c.type})" }

Again this is if you are looking pretty print to describe you ActiveRecord without you going trough migrations or hopping that developer before you was nice enough to comment in attributes.

I'm using Jetbrains Rider and it was a hassle copying the results from above examples to re-execute because it seemed to wrap it all in JSON. This joins them into a single statement that was easier to run

select string_agg('drop table if exists "' || tablename || '" cascade', ';') 
from pg_tables where schemaname != $$pg_catalog$$ and tableName like $$rm_%$$

One more option would be to run SQLSERVER discovery report..go to installation media of sqlserver and double click setup.exe

and in the next screen,go to tools and click discovery report as shown below

This will show you all the instances present along with entire features..below is a snapshot on my pc

Start the sub thread with setDaemon(True).

def bootstrap(_filename):
    mb = ModelBootstrap(filename=_filename) # Has many Daemon threads. All get stopped automatically when main thread is stopped.

t = threading.Thread(target=bootstrap,args=('models.conf',))
t.setDaemon(False)

while True:
    t.start()
    time.sleep(10) # I am just allowing the sub-thread to run for 10 sec. You can listen on an event to stop execution.
    print('Thread stopped')
    break

A great substitute for np.isnan() and pd.isnull() is

for i in range(0,a.shape[0]):
    if(a[i]!=a[i]):
       //do something here
       //a[i] is nan

since only nan is not equal to itself.

Xenph Yan's answer was far cleaner than mine but here is mine all the same.

DECLARE @startStr AS Varchar (20)
SET @startStr = 'tableName'

DECLARE @startStrLen AS int
SELECT @startStrLen = LEN(@startStr)

SELECT 'DROP TABLE ' + name FROM sysobjects
WHERE type = 'U' AND LEFT(name, @startStrLen) = @startStr

Just change tableName to the characters that you want to search with.

First, connect to the database:

$conn=mysql_connect("hostname","username","password");
mysql_select_db("databasename",$conn);

You can use this to display a single record:

For example, if the URL was /index.php?sequence=123, the code below would select from the table, where the sequence = 123.

<?php
$sql="SELECT * from table where sequence = '".$_GET["sequence"]."' ";
$rs=mysql_query($sql,$conn) or die(mysql_error());
$result=mysql_fetch_array($rs);

echo '<table>
<tr>
<td>Forename</td>
<td>Surname</td>
</tr>
<tr>
<td>'.$result["forename"].'</td>
<td>'.$result["surname"].'</td>
</tr>
</table>';
?>

Or, if you want to list all values that match the criteria in a table:

<?php
echo '<table>
<tr>
<td>Forename</td>
<td>Surname</td>
</tr>';
$sql="SELECT * from table where sequence = '".$_GET["sequence"]."' ";
$rs=mysql_query($sql,$conn) or die(mysql_error());
while($result=mysql_fetch_array($rs))
{
echo '<tr>
<td>'.$result["forename"].'</td>
<td>'.$result["surname"].'</td>
</tr>';
}
echo '</table>';
?>

Use net time net time \\timesrv /set /yes

I might be misunderstanding your question, so apologies if I am.

If you're looking for the words "Quid", "Application Number", etc. to be bold, just wrap them in <strong> tags:

<strong>Quid</strong>: ...

Hope that helps!

Use the substring method of the String class :

String removeCurrency=amount.getText().toString().substring(3);

Use an inline function rather than a macro. Besides, you need to store something in memory which is a not-so-nice side effect of a macro.

You could convert it to a short macro using a static or global variable, like this:

static int s_endianess = 0;
#define ENDIANESS() ((s_endianess = 1), (*(unsigned char*) &s_endianess) == 0)

Values not necessarily have to be unique so you have to do a lookup. You can do something like this:

var myKey = types.FirstOrDefault(x => x.Value == "one").Key;

If values are unique and are inserted less frequently than read, then create an inverse dictionary where values are keys and keys are values.

SELECT constraint_name, constraint_type, column_name
from user_constraints natural join user_cons_columns
where table_name = "my_table_name";

will give you what you need

Yes there is such a built-in function: os.path.join.

>>> import os.path
>>> os.path.join('/my/root/directory', 'in', 'here')
'/my/root/directory/in/here'

If you want to know the location of you NPM packages, you should:

which npm // locate a program file in the user's path SEE man which
// OUTPUT SAMPLE
/usr/local/bin/npm
la /usr/local/bin/npm // la: aliased to ls -lAh SEE which la THEN man ls
lrwxr-xr-x  1 t04435  admin    46B 18 Sep 10:37 /usr/local/bin/npm -> /usr/local/lib/node_modules/npm/bin/npm-cli.js

So given that npm is a NODE package itself, it is installed in the same location as other packages(EUREKA). So to confirm you should cd into node_modules and list the directory.

cd /usr/local/lib/node_modules/
ls
#SAMPLE OUTPUT
@angular npm .... all global npm packages installed

OR

npm root -g

As per @anthonygore 's comment

Replace '\n' with "\n". The escape sequence is not recognized when you use '.

See the manual.

For the question of how to write line endings, see the note here. Basically, different operating systems have different conventions for line endings. Windows uses "\r\n", unix based operating systems use "\n". You should stick to one convention (I'd chose "\n") and open your file in binary mode (fopen should get "wb", not "w").

In PyCharm the parameters are added in the Script Parameters as you did but, they are enclosed in double quotes "" and without specifying the Interpreter flags like -s. Those flags are specified in the Interpreter options box.

Script Parameters box contents:

"file1.txt" "file2.txt"

Interpeter flags:

-s

Or, visually:

Then, with a simple test file to evaluate:

if __name__ == "__main__":
    import sys
    print(sys.argv)

We get the parameters we provided (with sys.argv[0] holding the script name of course):

['/Path/to/current/folder/test.py', 'file1.txt', 'file2.txt']

You can invoke devenv.exe /diff list1.txt list2.txt from the VS Developer Command Prompt or, if a Visual Studio instance is already running, you can type Tools.DiffFiles in the Command window, with a handy file name completion:

One obvious and straightforward possibility is to use "if-else conditions". In that example

x <- c(1, 2, 4)
y <- c(1, 4, 5)
w <- ifelse(x <= 1, "good", ifelse((x >= 3) & (x <= 5), "bad", "fair"))
data.frame(x, y, w)

** For the additional question in the edit** Is that what you expect ?

> d1 <- c("e", "c", "a")
> d2 <- c("e", "a", "b")
> 
> w <- ifelse((d1 == "e") & (d2 == "e"), 1, 
+    ifelse((d1=="a") & (d2 == "b"), 2,
+    ifelse((d1 == "e"), 3, 99)))
>     
> data.frame(d1, d2, w)
  d1 d2  w
1  e  e  1
2  c  a 99
3  a  b  2

If you do not feel comfortable with the ifelse function, you can also work with the if and else statements for such applications.

The following css statement disables click events

pointer-events:none;

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

I had a similar problem. npm install --only=dev didn't work, and neither did npm rebuild. Ultimately, I had to delete node_modules and package-lock.json and run npm install again. That fixed it for me.

If that's a valid date/time entry then excel simply stores it as a number (days are integers and the time is the decimal part) so you can do a simple subtraction.

I'm not sure if 7/6 is 7th June or 6th July, assuming the latter then it's a future date so you can get the difference in days with

=INT(A1-TODAY())

Make sure you format result cell as general or number (not date)

In Java doc of Var-Args it is quite clear the usage of var args:

http://docs.oracle.com/javase/1.5.0/docs/guide/language/varargs.html

about usage it says:

"So when should you use varargs? As a client, you should take advantage of them whenever the API offers them. Important uses in core APIs include reflection, message formatting, and the new printf facility. As an API designer, you should use them sparingly, only when the benefit is truly compelling. Generally speaking, you should not overload a varargs method, or it will be difficult for programmers to figure out which overloading gets called. "

<script type="text/javascript">
    $(document).ready(function () {
        $('#btnadd').on('click', function () {
            var n1 = parseInt($('#txtn1').val());
            var n2 = parseInt($('#txtn2').val());
            var r = n1 + n2;
            alert("sum of 2 No= " + r);
            return false;
        });
        $('#btnclear').on('click', function () {
            $('#txtn1').val('');
            $('#txtn2').val('');
            $('#txtn1').focus();
            return false;
        });
    });
</script>

Actually, the onclick events will NOT fire when the user uses the keyboard to change the selection in the select control. You might have to use a combination of onChange and onClick to get the behavior you're looking for.

Maybe you want set -e:

www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:

This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.

Most people responding don't even seem to know what an array pointer is...

The problem is that you do pointer arithmetics with an array pointer: ptr + 1 will mean "jump 5 bytes ahead since ptr points at a 5 byte array".

Do like this instead:

#include <stdio.h>

int main()
{
  char (*ptr)[5];
  char arr[5] = {'a','b','c','d','e'};
  int i;

  ptr = &arr;
  for(i=0; i<5; i++)
  {
    printf("\nvalue: %c", (*ptr)[i]);
  }
}

Take the contents of what the array pointer points at and you get an array. So they work just like any pointer in C.

To avoid exceptions with .Parse, here are some .TryParse alternatives.

To use only the elements that can be parsed:

string[] arr = { null, " ", " 1 ", " 002 ", "3.0" };
int i = 0; 
var a = (from s in arr where int.TryParse(s, out i) select i).ToArray();  // a = { 1, 2 }

or

var a = arr.SelectMany(s => int.TryParse(s, out i) ? new[] { i } : new int[0]).ToArray();

Alternatives using 0 for the elements that can't be parsed:

int i; 
var a = Array.ConvertAll(arr, s => int.TryParse(s, out i) ? i : 0); //a = { 0, 0, 1, 2, 0 }

or

var a = arr.Select((s, i) => int.TryParse(s, out i) ? i : 0).ToArray();

C# 7.0:

var a = Array.ConvertAll(arr, s => int.TryParse(s, out var i) ? i : 0);

Use below code to get all attributes with details

    global $wpdb;

    $attribute_taxonomies = $wpdb->get_results( "SELECT * FROM " . $wpdb->prefix . "woocommerce_attribute_taxonomies WHERE attribute_name != '' ORDER BY attribute_name ASC;" );
    set_transient( 'wc_attribute_taxonomies', $attribute_taxonomies );

    $attribute_taxonomies = array_filter( $attribute_taxonomies  ) ;

    prin_r($attribute_taxonomies);

Try out this will solve ur problem ....

EditText etxt = (EditText)findviewbyid(R.id.etxt);
String str_value = etxt.getText().toString();

As you said, you have set of jobs, it need to be executed in certain order. Topological sort given you required order for scheduling of jobs(or for dependency problems if it is a direct acyclic graph). Run dfs and maintain a list, and start adding node in the beginning of the list, and if you encountered a node which is already visited. Then you found a cycle in given graph.

This comment from verybadbug under question helped me:

ln -s /etc/apache2/mods-available/rewrite.load /etc/apache2/mods-enabled/rewrite.load

After that we need restart Apache:

sudo service apache2 restart

You can use below code to scroll to bottom of div on page load.

$(document).ready(function(){
  $('div').scrollTop($('div').scrollHeight);
});

time.time() / datetime is good for quick use, but is not always 100% precise. For that reason, I like to use one of the std lib profilers (especially hotshot) to find out what's what.

As mentioned in another answer here, in Guideline 7-3 of the Java Secure Coding Guidelines, throwing an exception in the constructor of a non-final class opens a potential attack vector:

Guideline 7-3 / OBJECT-3: Defend against partially initialized instances of non-final classes When a constructor in a non-final class throws an exception, attackers can attempt to gain access to partially initialized instances of that class. Ensure that a non-final class remains totally unusable until its constructor completes successfully.

From JDK 6 on, construction of a subclassable class can be prevented by throwing an exception before the Object constructor completes. To do this, perform the checks in an expression that is evaluated in a call to this() or super().

    // non-final java.lang.ClassLoader
    public abstract class ClassLoader {
        protected ClassLoader() {
            this(securityManagerCheck());
        }
        private ClassLoader(Void ignored) {
            // ... continue initialization ...
        }
        private static Void securityManagerCheck() {
            SecurityManager security = System.getSecurityManager();
            if (security != null) {
                security.checkCreateClassLoader();
            }
            return null;
        }
    }

For compatibility with older releases, a potential solution involves the use of an initialized flag. Set the flag as the last operation in a constructor before returning successfully. All methods providing a gateway to sensitive operations must first consult the flag before proceeding:

    public abstract class ClassLoader {

        private volatile boolean initialized;

        protected ClassLoader() {
            // permission needed to create ClassLoader
            securityManagerCheck();
            init();

            // Last action of constructor.
            this.initialized = true;
        }
        protected final Class defineClass(...) {
            checkInitialized();

            // regular logic follows
            ...
        }

        private void checkInitialized() {
            if (!initialized) {
                throw new SecurityException(
                    "NonFinal not initialized"
                );
            }
        }
    }

Furthermore, any security-sensitive uses of such classes should check the state of the initialization flag. In the case of ClassLoader construction, it should check that its parent class loader is initialized.

Partially initialized instances of a non-final class can be accessed via a finalizer attack. The attacker overrides the protected finalize method in a subclass and attempts to create a new instance of that subclass. This attempt fails (in the above example, the SecurityManager check in ClassLoader's constructor throws a security exception), but the attacker simply ignores any exception and waits for the virtual machine to perform finalization on the partially initialized object. When that occurs the malicious finalize method implementation is invoked, giving the attacker access to this, a reference to the object being finalized. Although the object is only partially initialized, the attacker can still invoke methods on it, thereby circumventing the SecurityManager check. While the initialized flag does not prevent access to the partially initialized object, it does prevent methods on that object from doing anything useful for the attacker.

Use of an initialized flag, while secure, can be cumbersome. Simply ensuring that all fields in a public non-final class contain a safe value (such as null) until object initialization completes successfully can represent a reasonable alternative in classes that are not security-sensitive.

A more robust, but also more verbose, approach is to use a "pointer to implementation" (or "pimpl"). The core of the class is moved into a non-public class with the interface class forwarding method calls. Any attempts to use the class before it is fully initialized will result in a NullPointerException. This approach is also good for dealing with clone and deserialization attacks.

    public abstract class ClassLoader {

        private final ClassLoaderImpl impl;

        protected ClassLoader() {
            this.impl = new ClassLoaderImpl();
        }
        protected final Class defineClass(...) {
            return impl.defineClass(...);
        }
    }

    /* pp */ class ClassLoaderImpl {
        /* pp */ ClassLoaderImpl() {
            // permission needed to create ClassLoader
            securityManagerCheck();
            init();
        }

        /* pp */ Class defineClass(...) {
            // regular logic follows
            ...
        }
    }

urlresolver has been removed in the higher version of Django - Please upgrade your django installation. I fixed it using the following command.

pip install django==2.0 --upgrade

There is an easier way to do this. Let's assume you're on the master branch

Create a new orphaned branch which will remove all commit history:

$ git checkout --orphan new_branch

Add your initial commit message:

$ git commit -a

Get rid of the old unmerged master branch:

$ git branch -D master

Rename your current branch new_branch to master:

$ git branch -m master

I would recommend adding a boolean check for the magnitude of the number. I'm converting a high milliseconds value to datetime. I have numbers from 2 to 200,000,200 so 0 is a valid output. The function as @Chris Mueller has it will return 0 even if number is smaller than 10**n.

def get_digit(number, n):
    return number // 10**n % 10

get_digit(4231, 5)
# 0

def get_digit(number, n):
    if number - 10**n < 0:
        return False
    return number // 10**n % 10

get_digit(4321, 5)
# False

You do have to be careful when checking the boolean state of this return value. To allow 0 as a valid return value, you cannot just use if get_digit:. You have to use if get_digit is False: to keep 0 from behaving as a false value.

Here is the code of ReadDoc/docx.java: This will read a dox/docx file and print its content to the console. you can customize it your way.

        try
        {

            file = new File("c:\\New.doc");
            FileInputStream fis = new FileInputStream(file.getAbsolutePath());
            HWPFDocument document = new HWPFDocument(fis);
            extractor = new WordExtractor(document);
            String[] fileData = extractor.getParagraphText();
            for (int i = 0; i < fileData.length; i++)
            {
                if (fileData[i] != null)
                    System.out.println(fileData[i]);
            }
        }
        catch (Exception exep)
        {
            exep.printStackTrace();
        }
    }
}

The reason the ImageView's dimentions are 0 is because when you are querying them, the view still haven't performed the layout and measure steps. You only told the view how it would "behave" in the layout, but it still didn't calculated where to put each view.

How do you decide the size to give to the image view? Can't you simply use one of the scaling options natively implemented?

As @Kanmani hinted, an easier to interpret implementation may use numpy.flip, as in the following:

import numpy as np

avgDists = np.array([1, 8, 6, 9, 4])
ids = np.flip(np.argsort(avgDists))
print(ids)

By using the visitor pattern rather than member functions, it is easier to read the order of operations.

Stumbled upon this bug as well during development.

However, in my case it was caused by an underlying loop of functions calling eachother - as a result of continuous iterations during development.

For future reference by search engines - the exact error my logs provided me with was:

Exception: Maximum function nesting level of '256' reached, aborting!

If, like in my case, the given answers do not solve your problem, make sure you're not accidentally doing something along the lines of the following simplified situation:

function foo(){
    // Do something
    bar();
}

function bar(){
    // Do something else
    foo();
}

In this case, even if you set ini_set('xdebug.max_nesting_level', 9999); it will still print out the same error message in your logs.

This is a bit old but I ran into the requirement so here is the solution I came up with.

The Problem:

Our development team maintains many .NET web application products we are migrating to AngularJS/Bootstrap. VS2010 does not lend itself easily to custom build processes and my developers are routinely working on multiple releases of our products. Our VCS is Subversion (I know, I know. I'm trying to move to Git but my pesky marketing staff is so demanding) and a single VS solution will include several separate projects. I needed my staff to have a common method for initializing their development environment without having to install the same Node packages (gulp, bower, etc.) several times on the same machine.

TL;DR:

1. Need "npm install" to install the global Node/Bower development environment as well as all locally required packages for a .NET product.

2. Global packages should be installed only if not already installed.

3. Local links to global packages must be created automatically.

The Solution:

We already have a common development framework shared by all developers and all products so I created a NodeJS script to install the global packages when needed and create the local links. The script resides in "....\SharedFiles" relative to the product base folder:

/*******************************************************************************

Now if I want to update a global tool for our developers, I update the "packages" object and check in the new script. My developers check it out and either run it with "node npm-setup.js" or by "npm install" from any of the products under development to update the global environment. The whole thing takes 5 minutes.

In addition, to configure the environment for the a new developer, they must first only install NodeJS and GIT for Windows, reboot their computer, check out the "Shared Files" folder and any products under development, and start working.

The "package.json" for the .NET product calls this script prior to install:

{ 
"name"                    : "Books",
"description"             : "Node (npm) configuration for Books Database Web Application Tools",
"version"                 : "2.1.1",
"private"                 : true,

Notes

• Note the script reference requires forward slashes even in a Windows environment.

• "npm ls" will give "npm ERR! extraneous:" messages for all packages locally linked because they are not listed in the "package.json" "dependencies".

Edit 1/29/16

The updated npm-setup.js script above has been modified as follows:

• Package "version" in var packages is now the "package" value passed to npm install on the command line. This was changed to allow for installing packages from somewhere other than the registered repository.

• If the package is already installed but is not the one requested, the existing package is removed and the correct one installed.

• For reasons unknown, npm will periodically throw an EBUSY error (-4082) when performing an install or link. This error is trapped and the command re-executed. The error rarely happens a second time and seems to always clear up.

You cannot add style to an SVG <g> element. Its only purpose is to group children. That means, too, that style attributes you give to it are given down to its children, so a fill="green" on the <g> means an automatic fill="green" on its child <rect> (as long as it has no own fill specification).

Your only option is to add a new <rect> to the SVG and place it accordingly to match the <g> children's dimensions.

<!DOCTYPE html>
<html>
<body>

<p>Click the button to make a BUTTON element with text.</p>

<button onclick="myFunction()">Try it</button>

<script>
function myFunction() {
    var btn = document.createElement("BUTTON");
    var t = document.createTextNode("CLICK ME");

    btn.setAttribute("style","color:red;font-size:23px");

    btn.appendChild(t);
    document.body.appendChild(btn);

    btn.setAttribute("onclick", alert("clicked"));

}
</script>

</body>
</html>

The best practice is to explicitly list the columns:

Insert Into TableName(col1, col2,col2) Values(?, ?, ?)

Otherwise, your original insert will break if you add another column to your table.

Add the following to your conf file

fastcgi_buffers 16 16k; 
fastcgi_buffer_size 32k;

My issue was resolved After adding
sessionFactory.setPackagesToScan( new String[] { "com.springhibernate.model" }); Tested this Functionality in spring boot latest version 2.1.2.

Full Method:

 @Bean( name="sessionFactoryConfig")
    public LocalSessionFactoryBean sessionFactoryConfig() {

        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

        sessionFactory.setDataSource(dataSourceConfig());
        sessionFactory.setPackagesToScan(
                new String[] { "com.springhibernate.model" });

        sessionFactory.setHibernateProperties(hibernatePropertiesConfig());

        return sessionFactory;
    }

If all you have is a public key from a user in PuTTY-style format, you can convert it to standard openssh format like so:

ssh-keygen -i -f keyfile.pub > newkeyfile.pub

I keep forgetting this so I'm gonna write it here. Non-geeks, just keep walking.

The most common way to make a key on Windows is using Putty/Puttygen. Puttygen provides a neat utility to convert a linux private key to Putty format. However, what isn't addressed is that when you save the public key using puttygen it won't work on a linux server. Windows puts some data in different areas and adds line breaks.

The Solution: When you get to the public key screen in creating your key pair in puttygen, copy the public key and paste it into a text file with the extension .pub. You will save you sysadmin hours of frustration reading posts like this.

HOWEVER, sysadmins, you invariably get the wonky key file that throws no error message in the auth log except, no key found, trying password; even though everyone else's keys are working fine, and you've sent this key back to the user 15 times.

ssh-keygen -i -f keyfile.pub > newkeyfile.pub

Should convert an existing puttygen public key to OpenSSH format.

Expanding on the above answer from Sean DiSanti, I think the following is a simple and elegant solution that avoids having to loop over the array and won't give false positives due to partial matches

function is_in_array {
    local ELEMENT="${1}"
    local DELIM=","
    printf "${DELIM}%s${DELIM}" "${@:2}" | grep -q "${DELIM}${ELEMENT}${DELIM}"
}

Which can be called like so:

$ haystack=("needle1" "needle2" "aneedle" "spaced needle")
$ is_in_array "needle" "${haystack[@]}"
$ echo $?
1
$ is_in_array "needle1" "${haystack[@]}"
$ echo $?
0

In the <system.web> element, add the following element:

<httpCookies requireSSL="true" />

However, if you have a <forms> element in your system.web\authentication block, then this will override the setting in httpCookies, setting it back to the default false.

In that case, you need to add the requireSSL="true" attribute to the forms element as well.

So you will end up with:

<system.web>
    <authentication mode="Forms">
        <forms requireSSL="true">
            <!-- forms content -->
        </forms>
    </authentication>
</system.web>

See here and here for MSDN documentation of these elements.

MySQL WorkBench is free software and is developed by Oracle, you can import an SQL File or specify a database and it will generate an SQL Diagram which you can move around to make it more visually appealing. It runs on GNU/Linux and Windows and it's free and has a professional look..

In Python 3, you can use

"one" in d.values()

to test if "one" is among the values of your dictionary.

In Python 2, it's more efficient to use

"one" in d.itervalues()

instead.

Note that this triggers a linear scan through the values of the dictionary, short-circuiting as soon as it is found, so this is a lot less efficient than checking whether a key is present.

Use the format() function:

>>> format(14, '#010b')
'0b00001110'

The format() function simply formats the input following the Format Specification mini language. The # makes the format include the 0b prefix, and the 010 size formats the output to fit in 10 characters width, with 0 padding; 2 characters for the 0b prefix, the other 8 for the binary digits.

This is the most compact and direct option.

If you are putting the result in a larger string, use an formatted string literal (3.6+) or use str.format() and put the second argument for the format() function after the colon of the placeholder {:..}:

>>> value = 14
>>> f'The produced output, in binary, is: {value:#010b}'
'The produced output, in binary, is: 0b00001110'
>>> 'The produced output, in binary, is: {:#010b}'.format(value)
'The produced output, in binary, is: 0b00001110'

As it happens, even for just formatting a single value (so without putting the result in a larger string), using a formatted string literal is faster than using format():

>>> import timeit
>>> timeit.timeit("f_(v, '#010b')", "v = 14; f_ = format")  # use a local for performance
0.40298633499332936
>>> timeit.timeit("f'{v:#010b}'", "v = 14")
0.2850222919951193

But I'd use that only if performance in a tight loop matters, as format(...) communicates the intent better.

If you did not want the 0b prefix, simply drop the # and adjust the length of the field:

>>> format(14, '08b')
'00001110'

Here is a reference for using EXPLAIN PLAN with Oracle: http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/ex_plan.htm), with specific information about the columns found here: http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/ex_plan.htm#i18300

Your mention of 'FULL' indicates to me that the query is doing a full-table scan to find your data. This is okay, in certain situations, otherwise an indicator of poor indexing / query writing.

Generally, with explain plans, you want to ensure your query is utilizing keys, thus Oracle can find the data you're looking for with accessing the least number of rows possible. Ultimately, you can sometime only get so far with the architecture of your tables. If the costs remain too high, you may have to think about adjusting the layout of your schema to be more performance based.

You can always take the CTE, (Common Tabular Expression), approach.

;WITH updateCTE AS
(
    SELECT ID, TITLE 
    FROM HOLD_TABLE
    WHERE ID = 101
)

UPDATE updateCTE
SET TITLE = 'TEST';

The Go blog: Go maps in action has an excellent explanation.

When iterating over a map with a range loop, the iteration order is not specified and is not guaranteed to be the same from one iteration to the next. Since Go 1 the runtime randomizes map iteration order, as programmers relied on the stable iteration order of the previous implementation. If you require a stable iteration order you must maintain a separate data structure that specifies that order.

Here's my modified version of example code: http://play.golang.org/p/dvqcGPYy3-

package main

import (
    "fmt"
    "sort"
)

func main() {
    // To create a map as input
    m := make(map[int]string)
    m[1] = "a"
    m[2] = "c"
    m[0] = "b"

    // To store the keys in slice in sorted order
    keys := make([]int, len(m))
    i := 0
    for k := range m {
        keys[i] = k
        i++
    }
    sort.Ints(keys)

    // To perform the opertion you want
    for _, k := range keys {
        fmt.Println("Key:", k, "Value:", m[k])
    }
}

Output:

Key: 0 Value: b
Key: 1 Value: a
Key: 2 Value: c

You can use perl one-liners much like you do with sed, with the advantage of full perl regular expression support (which is much more powerful than what you get with sed). There is also very little variation across *nix platforms - perl is generally perl. So you can stop worrying about how to make your particular system's version of sed do what you want.

In this case, you can do

perl -pe 's/(regex)/\n$1/'

-pe puts perl into a "execute and print" loop, much like sed's normal mode of operation.

' quotes everything else so the shell won't interfere

() surrounding the regex is a grouping operator. $1 on the right side of the substitution prints out whatever was matched inside these parens.

Finally, \n is a newline.

Regardless of whether you are using parentheses as a grouping operator, you have to escape any parentheses you are trying to match. So a regex to match the pattern you list above would be something like

\(\d\d\d\)\d\d\d-\d\d\d\d

\( or \) matches a literal paren, and \d matches a digit.

Better:

\(\d{3}\)\d{3}-\d{4}

I imagine you can figure out what the numbers in braces are doing.

Additionally, you can use delimiters other than / for your regex. So if you need to match / you won't need to escape it. Either of the below is equivalent to the regex at the beginning of my answer. In theory you can substitute any character for the standard /'s.

perl -pe 's#(regex)#\n$1#'
perl -pe 's{(regex)}{\n$1}'

A couple final thoughts.

using -ne instead of -pe acts similarly, but doesn't automatically print at the end. It can be handy if you want to print on your own. E.g., here's a grep-alike (m/foobar/ is a regex match):

perl -ne 'if (m/foobar/) {print}'

If you are finding dealing with newlines troublesome, and you want it to be magically handled for you, add -l. Not useful for the OP, who was working with newlines, though.

Bonus tip - if you have the pcre package installed, it comes with pcregrep, which uses full perl-compatible regexes.

You can use LOWER function and UPPER function. Like

SELECT LOWER('THIS IS TEST STRING')

Result:

this is test string

And

SELECT UPPER('this is test string')

result:

THIS IS TEST STRING

You have to use System.Diagnostics.Process.

Use this CSS (jsFiddle example):

input:disabled.btn:hover,
input:disabled.btn:active,
input:disabled.btn:focus {
  color: green
}

You have to write the most outer element on the left and the most inner element on the right.

.btn:hover input:disabled would select any disabled input elements contained in an element with a class btn which is currently hovered by the user.

I would prefer :disabled over [disabled], see this question for a discussion: Should I use CSS :disabled pseudo-class or [disabled] attribute selector or is it a matter of opinion?
