I know this is an old thread but I think the Blaze library is worth checking out. It's built for these types of situations.

From the docs:

Blaze extends the usability of NumPy and Pandas to distributed and out-of-core computing. Blaze provides an interface similar to that of the NumPy ND-Array or Pandas DataFrame but maps these familiar interfaces onto a variety of other computational engines like Postgres or Spark.

Edit: By the way, it's supported by ContinuumIO and Travis Oliphant, author of NumPy.

You can use a JSON as well to store and send JS functions.

Check the following:

var myJSON = 
{
    "myFunc1" : function (){
        alert("a");
    }, 
    "myFunc2" : function (functionParameter){
        functionParameter();
    }
}



function main(){
    myJSON.myFunc2(myJSON.myFunc1);
}

This will print 'a'.

The following has the same effect with the above:

var myFunc1 = function (){
    alert('a');
}

var myFunc2 = function (functionParameter){
    functionParameter();
}

function main(){
    myFunc2(myFunc1);
}

Which is also has the same effect with the following:

function myFunc1(){
    alert('a');
}


function myFunc2 (functionParameter){
    functionParameter();
}

function main(){
    myFunc2(myFunc1);
}

And a object paradigm using Class as object prototype:

function Class(){
    this.myFunc1 =  function(msg){
        alert(msg);
    }

    this.myFunc2 = function(callBackParameter){
        callBackParameter('message');
    }
}


function main(){    
    var myClass = new Class();  
    myClass.myFunc2(myClass.myFunc1);
}

sudo nginx -t should test all files and return errors and warnings locations

Probably the easiest thing you can do is set the value to an empty string. This forces it to 'change' the file each time even if the same file is selected again.

<input type="file" value="" />

You need to return a Callable<> if you want spring.mvc.async.request-timeout=5000 to work.

@RequestMapping(method = RequestMethod.GET)
public Callable<String> getFoobar() throws InterruptedException {
    return new Callable<String>() {
        @Override
        public String call() throws Exception {
            Thread.sleep(8000); //this will cause a timeout
            return "foobar";
        }
    };
}

You can simply install an Android studio Martial icons plugin its name is please check plugin URL Material Design Icon Generator and check this GIF for more details:

This is mainly for creating the icons with required sizes, and it will be located directly in its folders.

You can simply use padding-left:60% (for ex) to align your content to right and simultaneously wrap the content in responsive container (I required navbar in my case) to ensure it works in all examples.

If you'd like to persisist cookies and session data, you'd best do it like this:

import requests

proxies = {
    'http': 'http://user:[email protected]:3128',
    'https': 'https://user:[email protected]:3128',
}

# Create the session and set the proxies.
s = requests.Session()
s.proxies = proxies

# Make the HTTP request through the session.
r = s.get('http://www.showmemyip.com/')

Just adding to the correct answers here for .net webapi2 users.

If you are using cors because your client site is served from a different address as your webapi then you need to also include SupportsCredentials=true on the server side configuration.

        // Access-Control-Allow-Origin
        // https://docs.microsoft.com/en-us/aspnet/web-api/overview/security/enabling-cross-origin-requests-in-web-api
        var cors = new EnableCorsAttribute(Settings.CORSSites,"*", "*");
        cors.SupportsCredentials = true;
        config.EnableCors(cors);

It is very late but preferably symbols should be used as key:

my_hash = {}
my_hash[:my_key] = 'value'

my_hash.has_key?("my_key")
 => false 
my_hash.has_key?("my_key".to_sym)
 => true 

my_hash2 = {}
my_hash2['my_key'] = 'value'

my_hash2.has_key?("my_key")
 => true 
my_hash2.has_key?("my_key".to_sym)
 => false 

But when creating hash if you pass string as key then it will search for the string in keys.

But when creating hash you pass symbol as key then has_key? will search the keys by using symbol.

If you are using Rails, you can use Hash#with_indifferent_access to avoid this; both hash[:my_key] and hash["my_key"] will point to the same record

Personally, I'd return the full, native datetime value and format this in the client code.

That way, you can use the user's locale setting to give the correct meaning to that user.

"11/12" is ambiguous. Is it:

• 12th November
• 11th December

None of the answers here quite hit the nail on the head.

How to store a datetime in MySQL with timezone info

Use two columns: DATETIME, and a VARCHAR to hold the time zone information, which may be in several forms:

A timezone or location such as America/New_York is the highest data fidelity.

A timezone abbreviation such as PST is the next highest fidelity.

A time offset such as -2:00 is the smallest amount of data in this regard.

Some key points:

• Avoid TIMESTAMP because it's limited to the year 2038, and MySQL relates it to the server timezone, which is probably undesired.
• A time offset should not be stored naively in an INT field, because there are half-hour and quarter-hour offsets.

If it's important for your use case to have MySQL compare or sort these dates chronologically, DATETIME has a problem:

'2009-11-10 11:00:00 -0500' is before '2009-11-10 10:00:00 -0700' in terms of "instant in time", but they would sort the other way when inserted into a DATETIME.

You can do your own conversion to UTC. In the above example, you would then have
'2009-11-10 16:00:00' and '2009-11-10 17:00:00' respectively, which would sort correctly. When retrieving the data, you would then use the timezone info to revert it to its original form.

One recommendation which I quite like is to have three columns:

• local_time DATETIME
• utc_time DATETIME
• time_zone VARCHAR(X) where X is appropriate for what kind of data you're storing there. (I would choose 64 characters for timezone/location.)

An advantage to the 3-column approach is that it's explicit: with a single DATETIME column, you can't tell at a glance if it's been converted to UTC before insertion.

Regarding the descent of accuracy through timezone/abbreviation/offset:

• If you have the user's timezone/location such as America/Juneau, you can know accurately what the wall clock time is for them at any point in the past or future (barring changes to the way Daylight Savings is handled in that location). The start/end points of DST, and whether it's used at all, are dependent upon location, so this is the only reliable way.
• If you have a timezone abbreviation such as MST, (Mountain Standard Time) or a plain offset such as -0700, you will be unable to predict a wall clock time in the past or future. For example, in the United States, Colorado and Arizona both use MST, but Arizona doesn't observe DST. So if the user uploads his cat photo at 14:00 -0700 during the winter months, was he in Arizona or California? If you added six months exactly to that date, would it be 14:00 or 13:00 for the user?

These things are important to consider when your application has time, dates, or scheduling as core function.

• from a directory_of_modules, you can import a specific_module.py
• this specific_module.py, can contain a Class with some_methods() or just functions()
• from a specific_module.py, you can instantiate a Class or call functions()
• from this Class, you can execute some_method()

Example:

#!/usr/bin/python3
from directory_of_modules import specific_module
instance = specific_module.DbConnect("username","password")
instance.login()

Excerpts from PEP 8 - Style Guide for Python Code:

Modules should have short and all-lowercase names.

Notice: Underscores can be used in the module name if it improves readability.

A Python module is simply a source file(*.py), which can expose:

• Class: names using the "CapWords" convention.

• Function: names in lowercase, words separated by underscores.

• Global Variables: the conventions are about the same as those for Functions.

 if ($("#Password").val() != $("#ConfirmPassword").val()) {
          alert("Passwords do not match.");
      }

A realtime priority thread can never be pre-empted by timer interrupts and runs at a higher priority than any other thread in the system. As such a CPU bound realtime priority thread can totally ruin a machine.

Creating realtime priority threads requires a privilege (SeIncreaseBasePriorityPrivilege) so it can only be done by administrative users.

For Vista and beyond, one option for applications that do require that they run at realtime priorities is to use the Multimedia Class Scheduler Service (MMCSS) and let it manage your threads priority. The MMCSS will prevent your application from using too much CPU time so you don't have to worry about tanking the machine.

You can use Dictonary to map Assume Milk,Butter,Chesse are group A (ListA) Water,Beer,Wine are group B

Dictonary<string,List<string>>) dataMap;
dataMap.add("A",ListA);
dataMap.add("B",ListB);

At View , you can foreach Keys in dataMap and process your action

Activity is a context so if you can simply check the context is an Activity and cast it if necessary.

@Override
public void onAttach(Context context) {
    super.onAttach(context);

    Activity a;

    if (context instanceof Activity){
        a=(Activity) context;
    }

}

Update: Some are claiming that the new Context override is never called. I have done some tests and cannot find a scenario where this is true and according to the source code, it should never be true. In all cases I tested, both pre and post SDK23, both the Activity and the Context versions of onAttach were called. If you can find a scenario where this is not the case, I would suggest you create a sample project illustrating the issue and report it to the Android team.

Update 2: I only ever use the Android Support Library fragments as bugs get fixed faster there. It seems the above issue where the overrides do not get called correctly only comes to light if you use the framework fragments.

You need the correct argument for the nth-child pseudo class.

• The argument should be in the form of an + b to match every a^th child starting from b.

• Both a and b are optional integers and both can be zero or negative.

  • If a is zero then there is no "every a^th child" clause.
  • If a is negative then matching is done backwards starting from b.
  • If b is zero or negative then it is possible to write equivalent expression using positive b e.g. 4n+0 is same as 4n+4. Likewise 4n-1 is same as 4n+3.

Examples:

Select every 4th child (4, 8, 12, ...)

li:nth-child(4n) {_x000D_
  background: yellow;_x000D_
}

Possibly too late to be of benefit now, but is this not the easiest way to do things?

SELECT     empName, projIDs = replace
                          ((SELECT Surname AS [data()]
                              FROM project_members
                              WHERE  empName = a.empName
                              ORDER BY empName FOR xml path('')), ' ', REQUIRED SEPERATOR)
FROM         project_members a
WHERE     empName IS NOT NULL
GROUP BY empName

Think I found the correct way to do it using ngx-bootstrap. First import following classes:

import { ViewChild } from '@angular/core';
import { BsModalService, ModalDirective } from 'ngx-bootstrap/modal';
import { BsModalRef } from 'ngx-bootstrap/modal/bs-modal-ref.service';

Inside the class implementation of your component add a @ViewCild property, a function to open the modal and do not forget to setup modalService as a private property inside the components class constructor:

@ViewChild('editSomething') editSomethingModal : TemplateRef<any>;
...

modalRef: BsModalRef;
openModal(template: TemplateRef<any>) {
  this.modalRef = this.modalService.show(template);
}
...
constructor(
private modalService: BsModalService) { }

The 'editSomething' part of the @ViewChild declaration refers to the component template file and its modal template implementation (#editSomething):

...
<ng-template #editSomething>
  <div class="modal-header">
  <h4 class="modal-title pull-left">Edit ...</h4>
  <button type="button" class="close pull-right" aria-label="Close" 
   (click)="modalRef.hide()">
    <span aria-hidden="true">&times;</span>
  </button>
  </div>

  <div class="modal-body">
    ...
  </div>


  <div class="modal-footer">
    <button type="button" class="btn btn-default"
        (click)="modalRef.hide()"
        >Close</button>
  </div>
</ng-template>

And finaly call the method to open the modal wherever you want like so:

console.log(this.editSomethingModal);
this.openModal( this.editSomethingModal );

this.editSomethingModal is a TemplateRef that could be shown by the ModalService.

Et voila! The modal defined in your component template file is shown by a call from inside your component class implementation. In my case I used this to show a modal from inside an event handler.

In the case where the process was spawned by another node process, like:

var child = spawn('gulp', ['watch'], {
    stdio: 'inherit',
});

And you try to kill it later, via:

child.kill();

This is how you handle the event [on the child]:

process.on('SIGTERM', function() {
    console.log('Goodbye!');
});

    function calculatePercentage($oldFigure, $newFigure)
{
    $percentChange = (($oldFigure - $newFigure) / $oldFigure) * 100;
    return round(abs($percentChange));
}

Grab the VLC Python module, vlc.py, which provides full support for libVLC and pop that in site-packages. Then:

>>> import vlc
>>> p = vlc.MediaPlayer("file:///path/to/track.mp3")
>>> p.play()

And you can stop it with:

>>> p.stop()

That module offers plenty beyond that (like pretty much anything the VLC media player can do), but that's the simplest and most effective means of playing one MP3.

You could play with os.path a bit to get it to find the path to the MP3 for you, given the filename and possibly limiting the search directories.

Full documentation and pre-prepared modules are available here. Current versions are Python 3 compatible.

This is really easy using jQuery.

$(".left").mouseover(function(){$(".left1").show()});
$(".left").mouseout(function(){$(".left1").hide()});

I've update your fiddle: http://jsfiddle.net/TqDe9/2/

On OSX Mavericks:

1. Create your shell script.

2. Make your shell script executable:

   chmod +x your-shell-script.sh
   

3. Rename your script to have a .app suffix:

   mv your-shell-script.sh your-shell-script.app
   

4. Drag the script to the OSX dock.

5. Rename your script back to a .sh suffix:

   mv your-shell-script.app your-shell-script.sh
   

6. Right-click the file in Finder, and click the "Get Info" option.
7. At the bottom of the window, set the shell script to open with the terminal.

Now when you click on the script in the dock, A terminal window will pop up and execute your script.

Bonus: To get the terminal to close when your script has completed, add exit 0 to the end and change the terminal settings to "close the shell if exited cleanly" like it says to do in this SO answer.

provide 400 permission, execute below command

chmod 400 /Users/username/.ssh/id_rsa

As far as I can tell, these lines in the Go compiler look like the ones to comment out. You should be able to build your own toolchain that ignores these counterproductive warnings.

With SemaphoreSlim you can achieve parallelism control.

var bag = new ConcurrentBag<object>();
var maxParallel = 20;
var throttler = new SemaphoreSlim(initialCount: maxParallel);
var tasks = myCollection.Select(async item =>
{
  try
  {
     await throttler.WaitAsync();
     var response = await GetData(item);
     bag.Add(response);
  }
  finally
  {
     throttler.Release();
  }
});
await Task.WhenAll(tasks);
var count = bag.Count;

In elasticsearch path home dir i.e. typically /usr/share/elasticsearch, There is a config file bin/elasticsearch.in.sh. Edit parameter ES_MIN_MEM, ES_MAX_MEM in this file to change -Xms2g, -Xmx4g respectively. And Please make sure you have restarted the node after this config change.

Also, if you got this error and installed mysql via Homebrew, I found that this works (though you need to change "5.6.12" to your own version):

/usr/local/Cellar/mysql/5.6.12/bin/mysql.server restart

I just created a file ~/restartMysql.sh in my home directory (with only the line above in it) so that I can just use this whenever MySQL is acting up

For those of you who, like me, come to this issue from Django, you should know that the docs provide a solution: https://docs.djangoproject.com/en/1.10/ref/models/fields/#foreignkey

"...To refer to models defined in another application, you can explicitly specify a model with the full application label. For example, if the Manufacturer model above is defined in another application called production, you’d need to use:

class Car(models.Model):
    manufacturer = models.ForeignKey(
        'production.Manufacturer',
        on_delete=models.CASCADE,
)

This sort of reference can be useful when resolving circular import dependencies between two applications...."

Try like this in sql query, It will work fine.

$sql="UPDATE create_test set url= '$_POST[url]' WHERE test_name='$test_name';";

If you have to update multiple columns, Use like this,

Many vendors implemented the Java specification and got TCK passed. For example, IBM J9, Azul Zulu, Azul Zing, and Oracle JDK.

Almost every existing JDK is derived from OpenJDK.

As suggested by many, licensing is a change between JDKs.

Starting with JDK 11 accessing the long time support Oracle JDK/Java SE will now require a commercial license. You should now pay attention to which JDK you're installing as Oracle JDK without subscription could stop working. source

I've tested a good product for that: AlwaysUp. Not free but they have a 30 days trial period so you can give it a try...

Ok I actually found the answer but thought I would 'import' the question into SO anyway

String[] files = new String[0];
or
int[] files = new int[0];

For me work like this: 1. Stop mysql: systemctl stop mysqld

2. Set the mySQL environment option systemctl set-environment MYSQLD_OPTS="--skip-grant-tables"

3. Start mysql usig the options you just set systemctl start mysqld

4. Login as root mysql -u root

5. After login I use FLUSH PRIVILEGES; tell the server to reload the grant tables so that account-management statements work. If i don't do that i receive this error trying to update the password: "Can't find any matching row in the user table"

If you want to add the id manually you can use,

PadLeft() or String.Format() method.

string id;
char x='0';
id=id.PadLeft(6, x);
//Six character string id with left 0s e.g 000012

int id;
id=String.Format("{0:000000}",id);
//Integer length of 6 with the id. e.g 000012

Then you can append this with UID.

I use this code and it works:

.slider - this is slider block

.count - selector which use for return counter

$(".slider").on("init", function(event, slick){
    $(".count").text(parseInt(slick.currentSlide + 1) + ' / ' + slick.slideCount);
});

$(".slider").on("afterChange", function(event, slick, currentSlide){
    $(".count").text(parseInt(slick.currentSlide + 1) + ' / ' + slick.slideCount);
});
$(".page-article-item_image-slider").slick({
    slidesToShow: 1,
    arrows: true
});

With ASP.NET 5 there is no Request variable available anymore. You can access it now with Context.Request

Also there is no IsAjaxRequest() Method anymore, you have to write it by yourself, for example in Extensions\HttpRequestExtensions.cs

using System;
using Microsoft.AspNetCore.Http;

namespace Microsoft.AspNetCore.Mvc
{
    public static class HttpRequestExtensions
    {
        public static bool IsAjaxRequest(this HttpRequest request)
        {
            if (request == null)
            {
                throw new ArgumentNullException(nameof(request));
            }

            return (request.Headers != null) && (request.Headers["X-Requested-With"] == "XMLHttpRequest");
        }
    }
}

I searched for a while now on this and hope that will help some others too ;)

Even if you don't have any third party editor (Notepad++ etc.) then also you can create files with dot as prefix.

To create .htaccess file, first create htaccess.txt file with Context Menu > New Text Document.

Then press Alt + D (Windows 7) and Ctrl + C to copy the path from the Address bar of Windows Explorer.

Then go to command line and type code as below to rename your file:

rename C:\path\to\htaccess.txt .htaccess

Now you have a blank .htaccess without opening it in any editor.

Hope this helps you out.

I found git here

C:\Users\<User>\AppData\Local\GitHubDesktop\app-0.5.8\resources\app\git\cmd\git.exe

You have to write file name (git.exe) in the end of path otherwise it will give an error=5

Or you can check here also.

C:\Program Files\Git\bin\git.exe

Solution for iOS10. Works fine.

NSURL *URL = [NSURL URLWithString:@"App-prefs:root=TWITTER"];
[[UIApplication sharedApplication] openURL:URL options:@{} completionHandler:nil];

Have a look at this

Appending the #value into the address is default behaviour that browsers such as IE use to identify named anchor positions on the page, seeing this comes from Netscape.

You can intercept it and remove it, read this article.

I was getting the same error. For Java version 7, following is working for me.

java.lang.System.setProperty("https.protocols", "TLSv1.2");

The canonical T-SQL (SqlServer) answer is to use a DELETE with JOIN as such

DELETE o
FROM Orders o
INNER JOIN Customers c
    ON o.CustomerId = c.CustomerId
WHERE c.FirstName = 'sklivvz'

This will delete all orders which have a customer with first name Sklivvz.

Taking advantage of @skip405's answer, I've made a Sass mixin for it:

@mixin inline-block-lr($container,$left,$right){
    #{$container}{        
        text-align: justify; 

        &:after{
            content: '';
            display: inline-block;
            width: 100%;
            height: 0;
            font-size:0;
            line-height:0;
        }
    }

    #{$left} {
        display: inline-block;
        vertical-align: middle; 
    }

    #{$right} {
        display: inline-block;
        vertical-align: middle; 
    }
}

It accepts 3 parameters. The container, the left and the right element. For example, to fit the question, you could use it like this:

@include inline-block-lr('header', 'h1', 'nav');

You need to alias the subquery.

SELECT name FROM (SELECT name FROM agentinformation) a  

or to be more explicit

SELECT a.name FROM (SELECT name FROM agentinformation) a  

in these cases you can try ssh if https is stuck.

Also you can try increasing the buffer size to an astronomical figure so that you dont have to worry about the buffer size any more git config http.postBuffer 100000000

v = alli.max()
index = alli.argmax()
x, y = index/8, index%8

You can set left margins for li tags in percents and set the same negative left margin on parent:

ul {margin-left:-5%;}_x000D_
li {width:20%;margin-left:5%;float:left;}

<ul>_x000D_
  <li>A_x000D_
  <li>B_x000D_
  <li>C_x000D_
  <li>D_x000D_
</ul>

None of the above answers worked for me. I have been 2 days working out the way to migrate a Vagrant + VirtualBox Machine from a computer to another... It's possible!

First, you need to understand that the virtual machine is separated from your sync / shared folder. So when you pack your machine you're packing it without your files, but with the databases.

What you need to do:

1- Open the CMD of your computer 1 host machine (Command line. Open it as Adminitrator with the right button -> "Run as administrator") and go to your vagrant installed files. On my case: C:/VVV You will see your Vagrantfile an also these folders:

/config/
/database/
/log/
/provision/
/www/
Vagrantfile
...

The /www/ folder is where I have my Sync Folder with my development domains. You may have your sync folder in other place, just be sure to understand what you are doing. Also /config and /database are sync folders.

2- run this command: vagrant package --vagrantfile Vagrantfile

(This command does a package of your virtual machine using you Vagrantfile configuration.)

Here's what you can read on the Vagrant documentation about the command:

A common misconception is that the --vagrantfile option will package a Vagrantfile that is used when vagrant init is used with this box. This is not the case. Instead, a Vagrantfile is loaded and read as part of the Vagrant load process when the box is used. For more information, read about the Vagrantfile load order.

https://www.vagrantup.com/docs/cli/package.html

When finnished, you will have a package.box file.

3- Copy all these files (/config, /database, Vagrantfile, package.box, etc.) and paste them on your Computer 2 just where you want to install your virtual machine (on my case D:/VVV).

Now you have a copy of everything you need on your computer 2 host.

4- run this: vagrant box add package.box --name VVV

(The --name is used to name your virtual machine. On my case it's named VVV) (You can use --force if you already have a virtual machine with this name and want to overwrite it. (Use carefully !))

This will unpack your new vagrant Virtual machine.

5- When finnished, run: vagrant up

The machine will install and you should see it on the "Oracle virtual machine box manager". If you cannot see the virtual machine, try running the Oracle VM box as administrator (right click -> Run as administrator)

You now may have everything ok but remember to see if your hosts are as you expected:

c:/windows/system32/hosts

6- Maybe it's a good idea to copy your host file from your Computer 1 to your Computer 2. Or copy the lines you need. In my case these are the hosts I need:

192.168.50.4 test.dev
192.168.50.4 vvv.dev
...

Where the 192.168.50.4 is the IP of my Virtual machine and test.dev and vvv.dev are developing hosts.

I hope this can help you :) I'll be happy if you feedback your go.

Some particularities of my case that you may find:

When I ran vagrant up, there was a problem with mysql, it wasn't working. I had to run on the Virtual server (right click on the oracle virtual machine -> Show console): apt-get install mysql-server

After this, I ran again vagrant up and everything was working but without data on the databases. So I did a mysqldump all-tables from the Computer 1 and upload them to Computer 2.

OTHER NOTES: My virtual machine is not exactly on Computer 1 and Computer 2. For example, I made some time ago internal configuration to use NFS (to speed up the server sync folders) and I needed to run again this command on the Computer 2 host: vagrant plugin install vagrant-winnfsd

Just to add my own opinion, in case it might be useful to someone. This is what I used.

<div th:class="${request.read ? 'mdl-color-text--grey-800 w500' : ''}"> </div>

See this answer to another question and the according part of the XML spec.

The backspace U+0008 is an invalid character in XML documents. It must be represented as escaped entity  and cannot occur plainly.

If you need to process this XML snippet, you must replace \x08 in s before feeding it into an XML parser.

Remove the server from IDE and install again to it.

sc queryex type= service state= all | find /i "NATION"

• use /i for case insensitive search
• the white space after type=is deliberate and required

Try GPU++ and libSh

LibSh link has a good description of how they bound the programming language to the graphics primitives (and obviously, the primitives themselves), and GPU++ describes what its all about, both with code examples.

A browser's default styles are defined in its user agent stylesheet, the sources of which you can find here. Unfortunately, the Cascading and Inheritance level 3 spec does not appear to propose a way to reset a style property to its browser default. However there are plans to reintroduce a keyword for this in Cascading and Inheritance level 4 — the working group simply hasn't settled on a name for this keyword yet (the link currently says revert, but it is not final). Information about browser support for revert can be found on caniuse.com.

While the level 3 spec does introduce an initial keyword, setting a property to its initial value resets it to its default value as defined by CSS, not as defined by the browser. The initial value of display is inline; this is specified here. The initial keyword refers to that value, not the browser default. The spec itself makes this note under the all property:

For example, if an author specifies all: initial on an element it will block all inheritance and reset all properties, as if no rules appeared in the author, user, or user-agent levels of the cascade.

This can be useful for the root element of a "widget" included in a page, which does not wish to inherit the styles of the outer page. Note, however, that any "default" style applied to that element (such as, e.g. display: block from the UA style sheet on block elements such as <div>) will also be blown away.

So I guess the only way right now using pure CSS is to look up the browser default value and set it manually to that:

div.foo { display: inline-block; }
div.foo.bar { display: block; }

(An alternative to the above would be div.foo:not(.bar) { display: inline-block; }, but that involves modifying the original selector rather than an override.)

This is my solution which works fairly well:

Both

gem query --local

and

 ruby -S gem list --local

list 69 entries

While

ruby -e 'puts Gem::Specification.all_names'

gives me 82

I used wc -l to get the numbers. Not sure if that is the right way to check. Tried to redirect the output to text files and diff'ed but that didn't help - will need to compare manually one by one.

Javadocs don't offer any special tools for external links, so you should just use standard html:

See <a href="http://groversmill.com/">Grover's Mill</a> for a history of the
Martian invasion.

or

@see <a href="http://groversmill.com/">Grover's Mill</a> for a history of 
the Martian invasion.

Don't use {@link ...} or {@linkplain ...} because these are for links to the javadocs of other classes and methods.

You can do this using Input.setSelectionRange, part of the Range API for interacting with text selections and the text cursor:

var searchInput = $('#Search');

// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;

searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);

Demo: Fiddle

http://pinvoke.net/default.aspx/user32.EnumDesktopWindows

There is an example of using user.dll's EnumWindow in C# to list all open windows.

You can use .toFixed() to for float value 2 digits

Exampale

let newValue = parseFloat(9.990000).toFixed(2)

//output
9.99

Actually ngAfterViewInit() will initiate only once when the component initiate.

If you really want a event triggers after the HTML element renter on the screen then you can use ngAfterViewChecked()

I noticed that there is another CSS selector that does the same thing . The syntax is as follows :

[id|="name_id"]

This will select all elements ID which begins with the word enclosed in double quotes.

<script type="text/javascript">
  function f1(mHref)
  {
    document.getElementById("abc").href=mHref; 
  }
</script>

<a href="" id="abc">jhg</a>
<button onclick="f1("dynamicHref")">Change HREF</button>

Just give the dynamic HREF in Paramters

from nltk.corpus import stopwords 

from nltk.tokenize import word_tokenize 

example_sent = "This is a sample sentence, showing off the stop words filtration."

  
stop_words = set(stopwords.words('english')) 
  
word_tokens = word_tokenize(example_sent) 
  
filtered_sentence = [w for w in word_tokens if not w in stop_words] 
  
filtered_sentence = [] 
  
for w in word_tokens: 
    if w not in stop_words: 
        filtered_sentence.append(w) 
  
print(word_tokens) 
print(filtered_sentence)

Just in case...
If you are using SoapUI Mock Service (as the Server), calling it from a C# WCF:

WCF --> SoapUI MockService

And in this case you are getting the same error:

The content type text/html; charset=UTF-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8).

Edit your Mock Response at SoapUI and add a Header to it:

In my scenario, this fix the problem.

In templates, you can separate filter arguments by colons.

{{ yourExpression | yourFilter: arg1:arg2:... }}

From Javascript, you call it as

$filter('yourFilter')(yourExpression, arg1, arg2, ...)

There is actually an example hidden in the orderBy filter docs.

Example:

Let's say you make a filter that can replace things with regular expressions:

myApp.filter("regexReplace", function() { // register new filter

  return function(input, searchRegex, replaceRegex) { // filter arguments

    return input.replace(RegExp(searchRegex), replaceRegex); // implementation

  };
});

Invocation in a template to censor out all digits:

<p>{{ myText | regexReplace: '[0-9]':'X' }}</p>

I was using a .Net Core 2.1 API with the [FromBody] attribute and I had to use the following solution to successfully Post to it:

_apiClient =  new HttpClient();
_apiClient.BaseAddress = new Uri(<YOUR API>);
var MyObject myObject = new MyObject(){
    FirstName = "Me",
    LastName = "Myself"
};

var stringified = JsonConvert.SerializeObject(myObject);
var result = await _apiClient.PostAsync("api/appusers", new StringContent(stringified, Encoding.UTF8, "application/json"));

If your delimiter is only characters, you can use strtok, which seems to be more fit here. Note that you must use it with a while loop to achieve the effects.

It's not compiling that's hurting me here, it's the typing. I could disable all the smart features and be back to notepad++ like TomTsagk suggested in a comment. For today I need more cores and RAM.

Playing devil's advocate I'd argue that typing shouldn't require a 16Gb PC octacore PC. Liked Sajan Rana's advice but things are so slow here it felt mostly a placebo.

To be fair I am using 1.4RC1, which is just short of being in the stable branch. Turning the internet off helped a little. The new feature of simultaneous Design (Preview) and Text views working with XML layouts is very helpful.

No, it is ridiculous. Never leave the stable channel.

The actual problem is with your

showList function.

There is an extra ')' after 'visible'.

Remove that and it will work fine.

function showList()
{
  if (document.getElementById("favSports").style.visibility == "hidden") 
    {
       // document.getElementById("favSports").style.visibility = "visible");  
       // your code
       document.getElementById("favSports").style.visibility = "visible";
       // corrected code
    }
}

You want the Thread.Join() method, or one of its overloads.

You should look at compareTo function of Date class.

JavaDoc

Subtracting 2 Date objects gives you the difference in milliseconds, e.g.:

var diff = Math.abs(new Date('2011/10/09 12:00') - new Date('2011/10/09 00:00'));

Math.abs is used to be able to use the absolute difference (so new Date('2011/10/09 00:00') - new Date('2011/10/09 12:00') gives the same result).

Dividing the result by 1000 gives you the number of seconds. Dividing that by 60 gives you the number of minutes. To round to whole minutes, use Math.floor or Math.ceil:

var minutes = Math.floor((diff/1000)/60);

In this example the result will be 720

If you only want to run the function given to useEffect after the initial render, you can give it an empty array as second argument.

function MyComponent() {
  useEffect(() => {
    loadDataOnlyOnce();
  }, []);

  return <div> {/* ... */} </div>;
}

Of course, Object.keys() is the best way to get an Object's keys. If it's not available in your environment, it can be trivially shimmed using code such as in your example (except you'd need to take into account your loop will iterate over all properties up the prototype chain, unlike Object.keys()'s behaviour).

However, your example code...

var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' };
var keys = [];
for (var key in foo) {
    keys.push(key);
}

jsFiddle.

...could be modified. You can do the assignment right in the variable part.

var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' };
var keys = [], i = 0;
for (keys[i++] in foo) {}

jsFiddle.

Of course, this behaviour is different to what Object.keys() actually does (jsFiddle). You could simply use the shim on the MDN documentation.

The wiki is talking from a forked repo point of view. You have access to pull and push from origin, which will be your fork of the main diaspora repo. To pull in changes from this main repo, you add a remote, "upstream" in your local repo, pointing to this original and pull from it.

So "origin" is a clone of your fork repo, from which you push and pull. "Upstream" is a name for the main repo, from where you pull and keep a clone of your fork updated, but you don't have push access to it.

You want to use single quotes:

if(c=='\0')

Double quotes (") are for strings, which are sequences of characters. Single quotes (') are for individual characters.

However, the end-of-line is represented by the newline character, which is '\n'.

Note that in both cases, the backslash is not part of the character, but just a way you represent special characters. Using backslashes you can represent various unprintable characters and also characters which would otherwise confuse the compiler.

In motherland Russia we have 4 popular encodings, so your question is in great demand here.

Only by char codes of symbols you can not detect encoding, because code pages intersect. Some codepages in different languages have even full intersection. So, we need another approach.

The only way to work with unknown encodings is working with probabilities. So, we do not want to answer the question "what is encoding of this text?", we are trying to understand "what is most likely encoding of this text?".

One guy here in popular Russian tech blog invented this approach:

Build the probability range of char codes in every encoding you want to support. You can build it using some big texts in your language (e.g. some fiction, use Shakespeare for english and Tolstoy for russian, lol ). You will get smth like this:

    encoding_1:
    190 => 0.095249209893009,
    222 => 0.095249209893009,
    ...
    encoding_2:
    239 => 0.095249209893009,
    207 => 0.095249209893009,
    ...
    encoding_N:
    charcode => probabilty

Next. You take text in unknown encoding and for every encoding in your "probability dictionary" you search for frequency of every symbol in unknown-encoded text. Sum probabilities of symbols. Encoding with bigger rating is likely the winner. Better results for bigger texts.

If you are interested, I can gladly help you with this task. We can greatly increase the accuracy by building two-charcodes probabilty list.

Btw. mb_detect_encoding certanly does not work. Yes, at all. Please, take a look of mb_detect_encoding source code in "ext/mbstring/libmbfl/mbfl/mbfl_ident.c".

Float won't convert into NVARCHAR directly, first we need to convert float into money datatype and then convert into NVARCHAR, see the examples below.

Example1

SELECT CAST(CAST(1234567890.1234  AS FLOAT) AS NVARCHAR(100))

output

1.23457e+009

Example2

SELECT CAST(CAST(CAST(1234567890.1234  AS FLOAT) AS MONEY) AS NVARCHAR(100))

output

1234567890.12

In Example2 value is converted into float to NVARCHAR

Are you sure you can't alter the HTML in the popup window?

If you can, add a <script> tag at the end of the popup's HTML, and call window.print() inside it. Then it won't be called until the HTML has loaded.

For new Qt users this is a little more confusing than it seems if you are using QT Designer and .ui files.

Initially I tried to use ui->setWindowTitle, but that doesn't exist. ui is not a QDialog or a QMainWindow.

The owner of the ui is the QDialog or QMainWindow, the .ui just describes how to lay it out. In that case, you would use:

this->setWindowTitle("New Title");

I hope this helps someone else.

Very simple:

#content {
    max-height: 100%;
}

Consider:

>>> a='asdf'
>>> a.__repr__
<method-wrapper '__repr__' of str object at 0x1091aab90>
>>> a='asdf'
>>> a.__repr__
<method-wrapper '__repr__' of str object at 0x1091aab90>
>>> a='qwer'
>>> a.__repr__
<method-wrapper '__repr__' of str object at 0x109198490>

Notice that the hex memory location did not change when I stored the same value in the variable twice. It did change when I stored a different value. The string is immutable. Not because of zealotry, but because you pay the performance penalty of creating a new object in memory. The variable a is just a label pointing to that memory address. It can be altered to point to anything.

1. Create a file for the jquery eg uploadfuntion.js.
2. Save that file in the same folder as website or in subfolder.
3. In head section of your html page paste: <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

and then the reference to your script eg: <script src="uploadfuntion.js"> </script>

4.Lastly you should ensure there are elements that match the selectors in the code.

You need to set the text after the replace call:

$('.element span').each(function() {_x000D_
  console.log($(this).text());_x000D_
  var text = $(this).text().replace('N/A, ', '');_x000D_
  $(this).text(text);_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div class="element">_x000D_
  <span>N/A, Category</span>_x000D_
</div>

Here's another cool way you can do it (hat tip @Felix King):

$(".element span").text(function(index, text) {
    return text.replace("N/A, ", "");
});

Yes it is deprecated. Replace your SessionFactory with the following:

In Hibernate 4.0, 4.1, 4.2

private static SessionFactory sessionFactory;
private static ServiceRegistry serviceRegistry;

public static SessionFactory createSessionFactory() {
    Configuration configuration = new Configuration();
    configuration.configure();
    ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(
            configuration.getProperties()). buildServiceRegistry();
    sessionFactory = configuration.buildSessionFactory(serviceRegistry);
    return sessionFactory;
}

UPDATE:

In Hibernate 4.3 ServiceRegistryBuilder is deprecated. Use the following instead.

serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
            configuration.getProperties()).build();

Using the onclick attribute or applying a function to your JS onclick properties will erase your onclick initialization in <head>.

What you need to do is add click events on your button. To do that you’ll need the addEventListener or attachEvent (IE) method.

<!DOCTYPE html>
<html>
<head>
    <script>
        function addEvent(obj, event, func) {
            if (obj.addEventListener) {
                obj.addEventListener(event, func, false);
                return true;
            } else if (obj.attachEvent) {
                obj.attachEvent('on' + event, func);
            } else {
                var f = obj['on' + event];
                obj['on' + event] = typeof f === 'function' ? function() {
                    f();
                    func();
                } : func
            }
        }

        function f1()
        {
            alert("f1 called");
            //form validation that recalls the page showing with supplied inputs.    
        }
    </script>
</head>
<body>
    <form name="form1" id="form1" method="post">
        State: <select id="state ID">
        <option></option>
        <option value="ap">ap</option>
        <option value="bp">bp</option>
        </select>
    </form>

    <table><tr><td id="Save" onclick="f1()">click</td></tr></table>

    <script>
        addEvent(document.getElementById('Save'), 'click', function() {
            alert('hello');
        });
    </script>
</body>
</html>

Even simpler:

$get = @mysql_query("SELECT money FROM players WHERE username = '" . $_SESSION['username'] . "'");

note the quotes around username in the $_SESSION reference.

UPDATE

If you don't need the exact look of a tab (bordered appropriately on the left or right as each tab is activated), you can simple use nav-stacked, along with Bootstrap col-* to float the tabs to the left or right...

nav-stacked demo: http://codeply.com/go/rv3Cvr0lZ4

<ul class="nav nav-pills nav-stacked col-md-3">
    <li><a href="#a" data-toggle="tab">1</a></li>
    <li><a href="#b" data-toggle="tab">2</a></li>
    <li><a href="#c" data-toggle="tab">3</a></li>
</ul>

You're looking for things like the haversine formula. See here as well.

There's other ones but this is the most commonly cited.

If you're looking for something even more robust, you might want to look at your databases GIS capabilities. They're capable of some cool things like telling you whether a point (City) appears within a given polygon (Region, Country, Continent).

I want to work with exec_query of the ActiveRecord class, because it returns the mapping of the query transforming into object, so it gets very practical and productive to iterate with the objects when the subject is Raw SQL.

Example:

values = ActiveRecord::Base.connection.exec_query("select * from clients")
p values

and return this complete query:

[{"id": 1, "name": "user 1"}, {"id": 2, "name": "user 2"}, {"id": 3, "name": "user 3"}]

To get only list of values

p values.rows

[[1, "user 1"], [2, "user 2"], [3, "user 3"]]

To get only fields columns

p values.columns

["id", "name"]

In python this work for me

self.set_your_value = "your value"

I've been doing it this way:

class Event(list):
    """Event subscription.

    A list of callable objects. Calling an instance of this will cause a
    call to each item in the list in ascending order by index.

    Example Usage:
    >>> def f(x):
    ...     print 'f(%s)' % x
    >>> def g(x):
    ...     print 'g(%s)' % x
    >>> e = Event()
    >>> e()
    >>> e.append(f)
    >>> e(123)
    f(123)
    >>> e.remove(f)
    >>> e()
    >>> e += (f, g)
    >>> e(10)
    f(10)
    g(10)
    >>> del e[0]
    >>> e(2)
    g(2)

    """
    def __call__(self, *args, **kwargs):
        for f in self:
            f(*args, **kwargs)

    def __repr__(self):
        return "Event(%s)" % list.__repr__(self)

However, like with everything else I've seen, there is no auto generated pydoc for this, and no signatures, which really sucks.

You may have .htaccess disallowed in webhost settings. Setting to default permalinks would work in that case.

Beware that calling Sleep() will freeze the service, so if the service is requested to stop, it won't react for the duration of the Sleep() call.

That sort of functionality is going to require some Javascript, but it is probably possible just to use CSS (in browsers other than IE6&7).

As written, there's nothing wrong with your code. Are you sure you haven't done something like

int strategy;
...
enum {RANDOM, IMMEDIATE, SEARCH} strategy;

What lines do the error messages point to? When it says "previous declaration of 'strategy' was here", what's "here" and what does it show?

To find a particular dropdown box element:

Select gender = new Select(driver.findElement(By.id("gender")));

To get the list of all the elements contained in the dropdown box:

for(int j=1;j<3;j++)
    System.out.println(gender.getOptions().get(j).getText());

To select it through visible text displayed when you click on it:

gender.selectByVisibleText("Male");

To select it by index (starting at 0):

gender.selectByIndex(1);

If you are reading from that file using FileStream and then wanting to delete it, make sure you close the FileStream before you call the File.Delete(path). I had this issue.

var filestream = new System.IO.FileStream(@"C:\Test\PutInv.txt", System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite);
filestream.Close();
File.Delete(@"C:\Test\PutInv.txt");

I too got the same issue, someone used BeanUtils.copyProperties(source, target). Here both source and target, are using the same collection as attribute.

So i just used the deep copy as below..

How to Clone Collection in Java - Deep copy of ArrayList and HashSet

Perhaps the error message is somewhat misleading, but the gist is that X_train is a list, not a numpy array. You cannot use array indexing on it. Make it an array first:

out_images = np.array(X_train)[indices.astype(int)]

StringBuffer is used to store character strings that will be changed (String objects cannot be changed). It automatically expands as needed. Related classes: String, CharSequence.

StringBuilder was added in Java 5. It is identical in all respects to StringBuffer except that it is not synchronized, which means that if multiple threads are accessing it at the same time, there could be trouble. For single-threaded programs, the most common case, avoiding the overhead of synchronization makes the StringBuilder very slightly faster.

You don't need a function at all. You can work on a whole column directly.

Example data:

>>> df = pd.DataFrame({'a': [100, 1000], 'b': [200, 2000], 'c': [300, 3000]})
>>> df

      a     b     c
0   100   200   300
1  1000  2000  3000

Half all the values in column a:

>>> df.a = df.a / 2
>>> df

     a     b     c
0   50   200   300
1  500  2000  3000

Rubygems.org has a guide that not only explains how to fix this problem, but also why so many people are having it: SSL Certificate Update The reason for the problem is rubygems.org switched to a more secure SSL certificate (SHA-2 which use 256bit encryption). The rubygems command line tool bundles the reference to the correct certificate. Therefore rubygems itself can’t be updated using an older version of rubygems. Rubygems must first be updated manually.

First find out what rubygems you have:

rubygems –v

Depending on whether you have a 1.8.x, 2.0.x or 2.2.x, you will need to download an update gem, named “rubygems-update-X.Y.Z.gem”, where X.Y.Z is the version you need. Running 1.8.x: download: https://github.com/rubygems/rubygems/releases/tag/v1.8.30 Running 2.0.x: download: https://github.com/rubygems/rubygems/releases/tag/v2.0.15 Running 2.2.x: download: https://github.com/rubygems/rubygems/releases/tag/v2.2.3

Install update gem:

gem install –-local full_path_to_the_gem_file

Run update gem:

update_rubygems --no-ri --no-rdoc

Check that rubygems was updated:

rubygems –v

Uninstall update gem:

gem uninstall rubygems-update -x

At this point, you may be OK. But it is possible that you do not have the latest public key file for the new certificate. To do this:

Download the latest certificate, (currently AddTrustExternalCARoot-2048.pem) from https://rubygems.org/pages/download. All of the certs are also located at: https://github.com/rubygems/rubygems/tree/master/lib/rubygems/ssl_certs

Find out where to put it:

gem which rubygems

Put this file in the “rubygems\ssl_certs” directory at this location.

As per rubygems commit, the certificates are moved to more specific directories. Thus, currently the certificate(AddTrustExternalCARoot-2048.pem) is expected to be on the following path lib/rubygems/ssl_certs/rubygems.org/AddTrustExternalCARoot-2048.pem

I have found a solution which helped me to get it done. Setting cache-view="false" on ion-view tag resolved my problem.

<ion-view cache-view="false" view-title="My Title!">
  ....
</ion-view>

Instead of relying only on <c:out />, an antixss library should also be used, which will not only encode but also sanitize malicious script in input. One of the best library available is OWASP Antisamy, it's highly flexible and can be configured(using xml policy files) as per requirement.

For e.g. if an application supports only text input then most generic policy file provided by OWASP can be used which sanitizes and removes most of the html tags. Similarly if application support html editors(such as tinymce) which need all kind of html tags, a more flexible policy can be use such as ebay policy file

Similar question asked and answered using JQuery here:

Get width height of remote image from url

function getMeta(url){
  $("<img/>").attr("src", url).load(function(){
     s = {w:this.width, h:this.height};
     alert(s.w+' '+s.h);      
  }); 
}

getMeta("http://page.com/img.jpg");

I was trying to call a REST endpoint from a microservice and I was using the resttemplate's put method.

In my design if any error occurred inside the REST endpoint it should return a JSON error response, it was working for some calls but not for this put one, it returned the white label error page instead.

So I did some investigation and I found out that;

Spring try to understand the caller if it is a machine then it returns JSON response or if it is a browser than it returns the white label error page HTML.

As a result: my client app needed to say to REST endpoint that the caller is a machine, not a browser so for this the client app needed to add 'application/json' into the ACCEPT header explicitly for the resttemplate's 'put' method. I added this to the header and solved the problem.

my call to the endpoint:

restTemplate.put(url, request, param1, param2);

for above call I had to add below header param.

headers.set("Accept", MediaType.APPLICATION_JSON_UTF8_VALUE);

or I tried to change put to exchange as well, in this case, exchange call added the same header for me and solved the problem too but I don't know why :)

restTemplate.exchange(....)

Yes,that is called short-circuiting.

Please take a look at this wikipedia page on short-circuiting

Sure, you can use JS's foreach.

for (var k in result) {
  something(result[k])
}

Even though the <head> and <body> tags aren't required, the elements are still there - it's just that the browser can work out where the tags would have been from the rest of the document.

The other elements you're using still have to be inside the <body>

Using

border: none;

doesn't work in some versions of IE. IE9 is fine but in previous versions it displays the border even when the style is "none". I experienced this when using a print stylesheet where I didn't want borders on the input boxes.

border: 0;

seems to work fine in all browsers.

Although I have attended the above, I have come to this point after many attempts. 1- If you want access to the certificate from the store, you can do this as an example 2- It is much easier and cleaner to produce the certificate and use it via a path

In MySQL, the word 'type' is a Reserved Word.

I started with the code from Dominic Barnes, incorporated the feedback from cWoDeR and I still had problems with the breadcrumbs at the third level when I used a sub-directory. So I rewrote it and have included the code below.

Note that I have set up my web site structure such that pages to be subordinate to (linked from) a page at the root level are set up as follows:

• Create a folder with the EXACT same name as the file (including capitalization), minus the suffix, as a folder at the root level

• place all subordinate files/pages into this folder

(eg, if want sobordinate pages for Customers.php:

• create a folder called Customers at the same level as Customers.php

• add an index.php file into the Customers folder which redirects to the calling page for the folder (see below for code)

This structure will work for multiple levels of subfolders.

Just make sure you follow the file structure described above AND insert an index.php file with the code shown in each subfolder.

The code in the index.php page in each subfolder looks like:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Redirected</title>
</head>
<body>
<?php 
$root_dir = "web_root/" ;
$last_dir=array_slice(array_filter(explode('/',$_SERVER['PHP_SELF'])),-2,1,false) ;
$path_to_redirect = "/".$root_dir.$last_dir[0].".php" ; 
header('Location: '.$path_to_redirect) ; 
?>
</body>
</html>

If you use the root directory of the server as your web root (ie /var/www/html) then set $root_dir="": (do NOT leave the trailing "/" in). If you use a subdirectory for your web site (ie /var/www/html/web_root then set $root_dir = "web_root/"; (replace web_root with the actual name of your web directory)(make sure to include the trailing /)

at any rate, here is my (derivative) code:

// Big Thank You to the folks on StackOverflow
// See http://stackoverflow.com/questions/2594211/php-simple-dynamic-breadcrumb
// Edited to enable using subdirectories to /var/www/html as root
// eg, using /var/www/html/<this folder> as the root directory for this web site
// To enable this, enter the name of the subdirectory being used as web root
// in the $directory2 variable below
// Make sure to include the trailing "/" at the end of the directory name
// eg use      $directory2="this_folder/" ;
// do NOT use  $directory2="this_folder" ;
// If you actually ARE using /var/www/html as the root directory,
// just set $directory2 = "" (blank)
// with NO trailing "/"

// This function will take $_SERVER['REQUEST_URI'] and build a breadcrumb based on the user's current path
function breadcrumbs($separator = ' &raquo; ' , $home = 'Home') 
{

    // This sets the subdirectory as web_root (If you want to use a subdirectory)
    // If you do not use a web_root subdirectory, set $directory2=""; (NO trailing /)
    $directory2 = "web_root/" ;

    // This gets the REQUEST_URI (/path/to/file.php), splits the string (using '/') into an array, and then filters out any empty values
    $path = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH) ;
    $path_array = array_filter(explode('/',$path)) ;

    // This line of code accommodates using a subfolder (/var/www/html/<this folder>) as root
    // This removes the first item in the array path so it doesn't repeat
    if ($directory2 != "")
    {
    array_shift($path_array) ;
    }

    // This will build our "base URL" ... Also accounts for HTTPS :)
    $base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/'. $directory2 ;

    // Initialize a temporary array with our breadcrumbs. (starting with our home page, which I'm assuming will be the base URL)
    $breadcrumbs = Array("<a href=\"$base\">$home</a>") ;

    // Get the index for the last value in our path array
    $last = end($path_array) ;

    // Initialize the counter
    $crumb_counter = 2 ;

    // Build the rest of the breadcrumbs
    foreach ($path_array as $crumb) 
    {
        // Our "title" is the text that will be displayed representing the filename without the .suffix
        // If there is no "." in the crumb, it is a directory
        if (strpos($crumb,".") == false)
        {
            $title = $crumb ;
        }
        else
        {
            $title = substr($crumb,0,strpos($crumb,".")) ;
        }

        // If we are not on the last index, then create a hyperlink
        if ($crumb != $last)
        {
            $calling_page_array = array_slice(array_values(array_filter(explode('/',$path))),0,$crumb_counter,false) ;
            $calling_page_path = "/".implode('/',$calling_page_array).".php" ;
            $breadcrumbs[] = "<a href=".$calling_page_path.">".$title."</a>" ;
        }

        // Otherwise, just display the title
        else
        {
            $breadcrumbs[] = $title ;
        }

        $crumb_counter = $crumb_counter + 1 ;

    }
    // Build our temporary array (pieces of bread) into one big string :)
    return implode($separator, $breadcrumbs) ;
}

// <p><?= breadcrumbs() ? ></p>
// <p><?= breadcrumbs(' > ') ? ></p>
// <p><?= breadcrumbs(' ^^ ', 'Index') ? ></p>
?>

Another variation is to split the pipe, and then re-direct the output as you like.

    @echo off
    for /f "tokens=1,* delims=:" %%P in ('findstr /n "^"') do (
      echo(%%Q
      echo(%%Q>&3
    )
    @exit/b %errorlevel%

Save the above to a .bat file. It splits text output on filestream 1 to filestream 3 also, which you can redirect as needed. In my examples below, I called the above script splitPipe.bat ...

    dir | splitPipe.bat  1>con  2>&1  3>my_stdout.log

    splitPipe.bat 2>nul < somefile.txt

create table employee
(
   empid int,
   empname varchar(40),
   designation varchar(30),
   hiredate datetime, 
   Bsalary int,
   depno constraint emp_m foreign key references department(depno)
)

We should have an primary key to create foreign key or relationship between two or more table .

Another option in SQL Server is to do all of your dynamic querying into table variable in a stored proc, then use a cursor to query and process that. As to the dreaded cursor debate :), I have seen studies that show that in some situations, a cursor can actually be faster if properly set up. I use them myself when the required query is too complex, or just not humanly (for me ;) ) possible.

I was having this exact problem, the above solutions didn't make much sense to me.

My Solution:

Turn of Bluetooth! Worked a treat ..

After connecting my macbook pro to iphone5 (hotspot) I started getting error message, after turning of bluetooth the error message is gone ..Hope that helps somebody!

I used this article to allow to c# to access to a sharepoint site.

http://www.thesharepointguide.com/access-office-365-using-a-console-application/

Basically you create a ClientId and ClientSecret keys to access to the site with c#

Hope this can help you!

Using list comprehensions in python, you can collect an entire column of values into a list using just two lines:

df = sqlContext.sql("show tables in default")
tableList = [x["tableName"] for x in df.rdd.collect()]

In the above example, we return a list of tables in database 'default', but the same can be adapted by replacing the query used in sql().

Or more abbreviated:

tableList = [x["tableName"] for x in sqlContext.sql("show tables in default").rdd.collect()]

And for your example of three columns, we can create a list of dictionaries, and then iterate through them in a for loop.

sql_text = "select name, age, city from user"
tupleList = [{name:x["name"], age:x["age"], city:x["city"]} 
             for x in sqlContext.sql(sql_text).rdd.collect()]
for row in tupleList:
    print("{} is a {} year old from {}".format(
        row["name"],
        row["age"],
        row["city"]))

Use preg_replace() and instead of [ \t\n\r] use \s:

$output = preg_replace('!\s+!', ' ', $input);

From Regular Expression Basic Syntax Reference:

\d, \w and \s

Shorthand character classes matching digits, word characters (letters, digits, and underscores), and whitespace (spaces, tabs, and line breaks). Can be used inside and outside character classes.

Why this answer is different

Every other answer either:

• Prints instead of returns
• Makes 2 recursive calls per iteration
• Ignores the question by using loops

(aside: none of these is actually efficient; use Binet's formula to directly calculate the n^th term)

Tail Recursive Fib

Here is a recursive approach that avoids a double-recursive call by passing both the previous answer AND the one before that.

private static final int FIB_0 = 0;
private static final int FIB_1 = 1;

private int calcFibonacci(final int target) {
    if (target == 0) { return FIB_0; }
    if (target == 1) { return FIB_1; }

    return calcFibonacci(target, 1, FIB_1, FIB_0);
}

private int calcFibonacci(final int target, final int previous, final int fibPrevious, final int fibPreviousMinusOne) {
    final int current = previous + 1;
    final int fibCurrent = fibPrevious + fibPreviousMinusOne;
    // If you want, print here / memoize for future calls

    if (target == current) { return fibCurrent; }

    return calcFibonacci(target, current, fibCurrent, fibPrevious);
}

in 2020 you want immutable and universal functions

This walk through your multidimensional object composed of sub-objects, arrays and string and apply a custom function

export const iterate = (object, func) => {
  const entries = Object.entries(object).map(([key, value]) =>
    Array.isArray(value)
      ? [key, value.map(e => iterate(e, func))]
      : typeof value === 'object'
      ? [key, iterate(value, func)]
      : [key, func(value)]
  );
  return Object.fromEntries(entries);
};

usage:

const r = iterate(data, e=>'converted_'+e);
console.log(r);

You can just check for null:

if(Request.QueryString["aspxerrorpath"]!=null)
{
   //your code that depends on aspxerrorpath here
}

Firstly, I'd recommend breaking the module up into the useful things you need. But you can always create a class extending that for your invocation:

module UsefulThings
  def a
    puts "aaay"
  end
  def b
    puts "beee"
  end
end

def test
  ob = Class.new.send(:include, UsefulThings).new
  ob.a
end

test

I downloaded a different installer "SQL Server 2014 Express with Advanced Services" and found Instance Features in it. Thanks for Alberto Solano's answer, it was really helpful.

My first installer was "SQL Server 2014 Express". It installed only SQL Management Studio and tools without Instance features. After installation "SQL Server 2014 Express with Advanced Services" my LocalDB is now alive!!!

server {

    index index.html index.htm;
    server_name test.example.com;

    location / {
        root /web/test.example.com/www;

    location /static {
        root /web/test.example.com;

Try isset($_POST['fromPerson'])?

If you are copying into a new table, the quickest way is probably what you have in your question, unless your rows are very large.

If your rows are very large, you may want to use the bulk insert functions in SQL Server. I think you can call them from C#.

Or you can first download that data into a text file, then bulk-copy (bcp) it. This has the additional benefit of allowing you to ignore keys, indexes etc.

Also try the Import/Export utility that comes with the SQL Management Studio; not sure whether it will be as fast as a straight bulk-copy, but it should allow you to skip the intermediate step of writing out as a flat file, and just copy directly table-to-table, which might be a bit faster than your SELECT INTO statement.

Great answer of Josh, all credit to him, I slightly modified it to this however:

MyDialog Xaml

    <StackPanel Margin="5,5,5,5">
        <TextBlock Name="TitleTextBox" Margin="0,0,0,10" />
        <TextBox Name="InputTextBox" Padding="3,3,3,3" />
        <Grid Margin="0,10,0,0">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <Button Name="BtnOk" Content="OK" Grid.Column="0" Margin="0,0,5,0" Padding="8" Click="BtnOk_Click" />
            <Button Name="BtnCancel" Content="Cancel" Grid.Column="1" Margin="5,0,0,0" Padding="8" Click="BtnCancel_Click" />
        </Grid>
    </StackPanel>

MyDialog Code Behind

    public MyDialog()
    {
        InitializeComponent();
    }

    public MyDialog(string title,string input)
    {
        InitializeComponent();
        TitleText = title;
        InputText = input;
    }

    public string TitleText
    {
        get { return TitleTextBox.Text; }
        set { TitleTextBox.Text = value; }
    }

    public string InputText
    {
        get { return InputTextBox.Text; }
        set { InputTextBox.Text = value; }
    }

    public bool Canceled { get; set; }

    private void BtnCancel_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Canceled = true;
        Close();
    }

    private void BtnOk_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Canceled = false;
        Close();
    }

And call it somewhere else

var dialog = new MyDialog("test", "hello");
dialog.Show();
dialog.Closing += (sender,e) =>
{
    var d = sender as MyDialog;
    if(!d.Canceled)
        MessageBox.Show(d.InputText);
}

If it helps...

I use the PHP function number_format() and the Narrow No-break Space ( ). It is often used as an unambiguous thousands separator.

echo number_format(200000, 0, "", " ");

Because IE8 has some problems to render the Narrow No-break Space, I changed it for a SPAN

echo "<span class='number'>".number_format(200000, 0, "", "<span></span>")."</span>";

.number SPAN{
    padding: 0 1px; 
}

You can use for Debian/Ubuntu:

dpkg -l|grep kafka

Expected result should to be like:

Rehash of Doogle's answer that doesn't printline numbers, but does allow specifying the number of lines to print.

def history(lastn=None):
    """
    param: lastn Defaults to None i.e full history. If specified then returns lastn records from history.
           Also takes -ve sequence for first n history records.
    """
    import readline
    assert lastn is None or isinstance(lastn, int), "Only integers are allowed."
    hlen = readline.get_current_history_length()
    is_neg = lastn is not None and lastn < 0
    if not is_neg:
        for r in range(1,hlen+1) if not lastn else range(1, hlen+1)[-lastn:]:
            print(readline.get_history_item(r))
    else:
        for r in range(1, -lastn + 1):
            print(readline.get_history_item(r))

Another option is to create an extra wrapper to center the element vertically.

#container{_x000D_
  border:solid 1px #33aaff;_x000D_
  width:200px;_x000D_
  height:200px;_x000D_
}_x000D_
_x000D_
#helper{_x000D_
  position:relative;_x000D_
  height:50px;_x000D_
  top:50%;_x000D_
  border:dotted 1px #ff55aa;_x000D_
}_x000D_
_x000D_
#centered{_x000D_
  position:relative;_x000D_
  height:50px;_x000D_
  top:-50%;_x000D_
  border:solid 1px #ff55aa;_x000D_
}

<div id="container">_x000D_
  <div id="helper">_x000D_
    <div id="centered"></div>_x000D_
  </div>_x000D_
<div>

You can compare the length of the string with one where the commas are removed:

len(value) - len(replace(value,',',''))

It was not the clock for me, and all the hours spent re-downloading and reinstalling were a waste of time (except for the last one, of course....).

Also, for some odd reason, just adding Read permissions to the HKCR node using psexec -i -s regedit did not work by itself.

To fix my problem on Windows 7, I made sure (using psexec -i -s regedit) that my login account had full control permission over every node in the registry and that the everyone group had read permission over every node in the registry, and did all of the steps in the following link (rebooting after each step):

http://windows.microsoft.com/troubleshootwindows7sp1

This is probably overkill, but after spending 10+ hours trying to get this working, I am just happy it works... Good luck!

How many ways can we skin this cat? Here is yet another variant.

SELECT * FROM table WHERE DATE(FROM_UNIXTIME(timestamp)) = '2015-11-18';

This is here:

 <button onClick="window.location='page_name.php';" value="click here" />

since no one suggested any solution, here is how i solved so far

year, month= divmod(mydate.month+1, 12)
if month == 0: 
      month = 12
      year = year -1
next_month = datetime.datetime(mydate.year + year, month, 1)

ASPX file:

<h2><p>Notify:</p> <asp:Literal runat="server" ID="ltNotify" /></h2>

ASPX.CS file:

ltNotify.Text = "Alert!";

I have spent a couple of hours looking for the magic configuration to get Tomcat 7 running as a service on Windows Server 2008... no luck.

I do have a solution though.

My install of Tomcat 7 works just fine if I just jump into a console window and run...

C:\apache-tomcat-7.0.26\bin\start.bat

At this point another console window pops up and tails the logs (tail meaning show the server logs as they happen).

SOLUTION

Run the start.bat file as a Scheduled Task.

1. Start Menu > Accessories > System Tools > Task Scheduler

2. In the Actions Window: Create Basic Task...

3. Name the task something like "Start Tomcat 7" or something that makes sense a year from now.

4. Click Next >

5. Trigger should be set to "When the computer starts"

6. Click Next >

7. Action should be set to "Start a program"

8. Click Next >

9. Program/script: should be set to the location of the startup.bat file.

10. Click Next >

11. Click Finish

12. IF YOUR SERVER IS NOT BEING USED: Reboot your server to test this functionality

What worked for me

import databricks.koalas as ks

df1k = df1.to_koalas()
df2k = df2.to_koalas()
df3k = df1k.merge(df2k, on=['col1', 'col2'])
df3 = df3k.to_spark()

All of the columns except for col1 and col2 had "_x" appended to their names if they had come from df1 and "_y" appended if they had come from df2, which is exactly what I needed.

Use this code:

public static void main(String[] args) {
    String test = "A|B|C||D";

    String[] result = test.split("\\|");

    for (String s : result) {
        System.out.println(">" + s + "<");
    }
}

I am fairly new to Javascript. But this is what I understood: JSON.parse() returns SyntaxError exceptions when invalid JSON is provided as its first parameter. So. It would be better to catch that exception as such like as follows:

try {
    let sData = `
        {
            "id": "1",
            "name": "UbuntuGod",
        }
    `;
    console.log(JSON.parse(sData));
} catch (objError) {
    if (objError instanceof SyntaxError) {
        console.error(objError.name);
    } else {
        console.error(objError.message);
    }
}

The reason why I made the words "first parameter" bold is that JSON.parse() takes a reviver function as its second parameter.

You should probably read some JS tutorials like this one.

Not sure if goto exists in JS at all, but, either way, it encourages bad coding style and should be avoided.

You could do:

while ( some_condition ){
    alert('RINSE');
    alert('LATHER');
}

$.ajax({
            type : 'GET',
            url : '${pageContext.request.contextPath}/order/lastOrder',
            data : {partyId : partyId, orderId :orderId},
            success : function(data, textStatus, jqXHR) });

@RequestMapping(value = "/lastOrder", method=RequestMethod.GET)
public @ResponseBody OrderBean lastOrderDetail(@RequestParam(value="partyId") Long partyId,@RequestParam(value="orderId",required=false) Long orderId,Model m ) {}

Assuming that your original dataset is similar to the one you created (i.e. with NA as character. You could specify na.strings while reading the data using read.table. But, I guess NAs would be detected automatically.

The price column is factor which needs to be converted to numeric class. When you use as.numeric, all the non-numeric elements (i.e. "NA", FALSE) gets coerced to NA) with a warning.

library(dplyr)
df %>%
     mutate(price=as.numeric(as.character(price))) %>%  
     group_by(company, year, product) %>%
     summarise(total.count=n(), 
               count=sum(is.na(price)), 
               avg.price=mean(price,na.rm=TRUE),
               max.price=max(price, na.rm=TRUE))

data

I am using the same dataset (except the ... row) that was showed.

df = tbl_df(data.frame(company=c("Acme", "Meca", "Emca", "Acme", "Meca","Emca"),
 year=c("2011", "2010", "2009", "2011", "2010", "2013"), product=c("Wrench", "Hammer",
 "Sonic Screwdriver", "Fairy Dust", "Kindness", "Helping Hand"), price=c("5.67",
 "7.12", "12.99", "10.99", "NA",FALSE)))

From Python 3 documentation (the same holds for python 2.7):

Curly braces or the set() function can be used to create sets. Note: to create an empty set you have to use set(), not {}; the latter creates an empty dictionary, a data structure that we discuss in the next section.

in python 2.7:

>>> my_set = {'foo', 'bar', 'baz', 'baz', 'foo'}
>>> my_set
set(['bar', 'foo', 'baz'])

Be aware that {} is also used for map/dict:

>>> m = {'a':2,3:'d'}
>>> m[3]
'd'
>>> m={}
>>> type(m)
<type 'dict'> 

One can also use comprehensive syntax to initialize sets:

>>> a = {x for x in """didn't know about {} and sets """ if x not in 'set' }
>>> a
set(['a', ' ', 'b', 'd', "'", 'i', 'k', 'o', 'n', 'u', 'w', '{', '}'])

You can get yesterday's date by using the expression CAST(NOW() - INTERVAL 1 DAY AS DATE). So something like this might work:

SELECT * FROM your_table

WHERE DateVisited >= UNIX_TIMESTAMP(CAST(NOW() - INTERVAL 1 DAY AS DATE))
  AND DateVisited <= UNIX_TIMESTAMP(CAST(NOW() AS DATE));

My case:

Missing node-sass in package.json

Solution:

1. npm i --save node-sass@latest
2. remove node-modules folder
3. npm i
4. check "@angular-devkit/build-angular": "^0.901.0" version in package.json

The minus sign (-) can convert positive numbers to negative numbers and negative numbers to positive numbers. x=-y is visual sugar for x=(y*-1).

var y = -100;
var x =- y;

The probable reason why you get this error is likely because you've added the /build folder to your .gitignore file or generally haven't checked it into Git.

So when you Git push Heroku master, the build folder you're referencing don't get pushed to Heroku. And that's why it shows this error.

That's the reason it works properly locally, but not when you deployed to Heroku.

You can do this using a group by:

select id, addressCode
from t
group by id, addressCode
having min(address) <> max(address)

Another way of writing this may seem clearer, but does not perform as well:

select id, addressCode
from t
group by id, addressCode
having count(distinct address) > 1

<?php if($condition) : ?>
    <a href="http://yahoo.com">This will only display if $condition is true</a>
<?php endif; ?>

By request, here's elseif and else (which you can also find in the docs)

<?php if($condition) : ?>
    <a href="http://yahoo.com">This will only display if $condition is true</a>
<?php elseif($anotherCondition) : ?>
    more html
<?php else : ?>
    even more html
<?php endif; ?>

It's that simple.

The HTML will only be displayed if the condition is satisfied.

div.noWrap {
    display: inline;
    }

I struggled with this topic for some time, and eventually went with the simplest approach that is still consistent with MVVM: Have the button execute the Command that does all the heavy lifting and have the button's Click handler close the window.

XAML

<Button x:Name="buttonOk" 
        Click="closeWindow" 
        Command="{Binding SaveCommand}" />

XAML.cs

public void closeWindow() 
{
    this.DialogResult = true;
}

SaveCommand.cs

 // I'm in my own file, not the code-behind!

True, there is still code-behind, but there isn't anything inherently bad about that. And it makes the most sense to me, from an OO perspective, to just tell the window to close itself.

TL;DR: Scan down to image, and then check out working project here.

Updating my answer for a simpler solution that I found..

In my case, I wanted to fix the width, and have variable height cells. I wanted a drop in, reusable solution that handled rotation and didn't require a lot of intervention.

What I arrived at, was override (just) systemLayoutFitting(...) in the collection cell (in this case a base class for me), and first defeat UICollectionView's effort to set the wrong dimension on contentView by adding a constraint for the known dimension, in this case, the width.

class EstimatedWidthCell: UICollectionViewCell {
    override init(frame: CGRect) {
        super.init(frame: frame)
        contentView.translatesAutoresizingMaskIntoConstraints = false
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        contentView.translatesAutoresizingMaskIntoConstraints = false
    }

    override func systemLayoutSizeFitting(
        _ targetSize: CGSize, withHorizontalFittingPriority
        horizontalFittingPriority: UILayoutPriority,
        verticalFittingPriority: UILayoutPriority) -> CGSize {

        width.constant = targetSize.width

and then return the final size for the cell - used for (and this feels like a bug) the dimension of the cell itself, but not contentView - which is otherwise constrained to a conflicting size (hence the constraint above). To calculate the correct cell size, I use a lower priority for the dimension that I wanted to float, and I get back the height required to fit the content within the width to which I want to fix:

        let size = contentView.systemLayoutSizeFitting(
            CGSize(width: targetSize.width, height: 1),
            withHorizontalFittingPriority: .required,
            verticalFittingPriority: verticalFittingPriority)

        print("\(#function) \(#line) \(targetSize) -> \(size)")
        return size
    }

    lazy var width: NSLayoutConstraint = {
        return contentView.widthAnchor
            .constraint(equalToConstant: bounds.size.width)
            .isActive(true)
    }()
}

But where does this width come from? It is configured via the estimatedItemSize on the collection view's flow layout:

lazy var collectionView: UICollectionView = {
    let view = UICollectionView(frame: CGRect(), collectionViewLayout: layout)
    view.backgroundColor = .cyan
    view.translatesAutoresizingMaskIntoConstraints = false
    return view
}()

lazy var layout: UICollectionViewFlowLayout = {
    let layout = UICollectionViewFlowLayout()
    let width = view.bounds.size.width // should adjust for inset
    layout.estimatedItemSize = CGSize(width: width, height: 10)
    layout.scrollDirection = .vertical
    return layout
}()

Finally, to handle rotation, I implement trailCollectionDidChange to invalidate the layout:

override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
    layout.estimatedItemSize = CGSize(width: view.bounds.size.width, height: 10)
    layout.invalidateLayout()
    super.traitCollectionDidChange(previousTraitCollection)
}

The final result looks like this:

And I have published a working sample here.

Assuming you have some level of control over the protocol, I'm a big fan of sending heartbeats to verify that a connection is active. It's proven to be the most fail proof method and will often give you the quickest notification when a connection has been broken.

TCP keepalives will work, but what if the remote host is suddenly powered off? TCP can take a long time to timeout. On the other hand, if you have logic in your app that expects a heartbeat reply every x seconds, the first time you don't get them you know the connection no longer works, either by a network or a server issue on the remote side.

See Do I need to heartbeat to keep a TCP connection open? for more discussion.

You can use SilverLight to launch an application from the browser (this will work only on IE and Firefox, newer versions of chrome don't support this)

Example code here

Try like this...

select CONVERT (varchar(10), getdate(), 103) AS [DD/MM/YYYY]

For more info : http://www.sql-server-helper.com/tips/date-formats.aspx

One more :

var a = document.createElement('a');
a.setAttribute('href', dataUri);
a.setAttribute('download', filename);

var aj = $(a);
aj.appendTo('body');
aj[0].click();
aj.remove();

If another part of your code has already made a connection with the same socket and UUID, you get this error.

We can use summary on factor column:

summary(myDF$factorColumn)

The Invalidate() Method will cause a repaint.

Nil Coalescing Operator can be used as well.

rowName = rowName != nil ?rowName!.stringFromCamelCase():""

If you are java 1.6 then the following can also be done:

import javax.tools.JavaCompiler; 
import javax.tools.ToolProvider; 

public class CompilerExample {

    public static void main(String[] args) {
        String fileToCompile = "/Users/rupas/VolatileExample.java";

        JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();

        int compilationResult = compiler.run(null, null, null, fileToCompile);

        if (compilationResult == 0) {
            System.out.println("Compilation is successful");
        } else {
            System.out.println("Compilation Failed");
        }
    }
}

Run dos2unix or similar utility on it to remove the carriage returns (^M).

This message indicates that your file has dos-style lineendings:

-bash: /backup/backup.sh: /bin/bash^M: bad interpreter: No such file or directory 

Utilities like dos2unix will fix it:

 dos2unix <backup.bash >improved-backup.sh 

Or, if no such utility is installed, you can accomplish the same thing with translate:

tr -d "\015\032" <backup.bash >improved-backup.sh 

As for how those characters got there in the first place, @MadPhysicist had some good comments.

try cleaning the solution or clean your project, this worked for me

Both async and defer scripts begin to download immediately without pausing the parser and both support an optional onload handler to address the common need to perform initialization which depends on the script.

The difference between async and defer centers around when the script is executed. Each async script executes at the first opportunity after it is finished downloading and before the window’s load event. This means it’s possible (and likely) that async scripts are not executed in the order in which they occur in the page. Whereas the defer scripts, on the other hand, are guaranteed to be executed in the order they occur in the page. That execution starts after parsing is completely finished, but before the document’s DOMContentLoaded event.

It defines an XML Namespace.

In your example, the Namespace Prefix is "android" and the Namespace URI is "http://schemas.android.com/apk/res/android"

In the document, you see elements like: <android:foo />

Think of the namespace prefix as a variable with a short name alias for the full namespace URI. It is the equivalent of writing <http://schemas.android.com/apk/res/android:foo /> with regards to what it "means" when an XML parser reads the document.

NOTE: You cannot actually use the full namespace URI in place of the namespace prefix in an XML instance document.

Check out this tutorial on namespaces: http://www.sitepoint.com/xml-namespaces-explained/

Try this.

First create a RoutedCommand object:

RoutedCommand newCmd = new RoutedCommand();
newCmd.InputGestures.Add(new KeyGesture(Key.N, ModifierKeys.Control));
CommandBindings.Add(new CommandBinding(newCmd, btnNew_Click));

Here is a good starting point.

HTML:

<div class="containing-table">
    <div class="centre-align">
        <div class="content"></div>
    </div>
</div>

CSS:

.containing-table {
    display: table;
    width: 100%;
    height: 400px; /* for demo only */
    border: 1px dotted blue;
}
.centre-align {
    padding: 10px;
    border: 1px dashed gray;
    display: table-cell;
    text-align: center;
    vertical-align: middle;
}
.content {
    width: 50px;
    height: 50px;
    background-color: red;
    display: inline-block;
    vertical-align: top; /* Removes the extra white space below the baseline */
}

See demo at: http://jsfiddle.net/audetwebdesign/jSVyY/

.containing-table establishes the width and height context for .centre-align (the table-cell).

You can apply text-align and vertical-align to alter .centre-align as needed.

Note that .content needs to use display: inline-block if it is to be centered horizontally using the text-align property.

One liner:

total_line_count = sum(1 for line in open("filename.txt"))

print(total_line_count)

git reset --hard <tag/branch/commit id>

Notes:

• git reset without the --hard option resets the commit history, but not the files. With the --hard option the files in working tree are also reset. (credited user)

• If you wish to commit that state so that the remote repository also points to the rolled back commit do: git push <reponame> -f (credited user)

Expanding from Andriy M, and yes you can do this from a file, even one with multiple lines

@echo off
setlocal EnableExtensions EnableDelayedExpansion
set "INTEXTFILE=test.txt"
set "OUTTEXTFILE=test_out.txt"
set "SEARCHTEXT=bath"
set "REPLACETEXT=hello"

for /f "delims=" %%A in ('type "%INTEXTFILE%"') do (
    set "string=%%A"
    set "modified=!string:%SEARCHTEXT%=%REPLACETEXT%!"
    echo !modified!>>"%OUTTEXTFILE%"
)

del "%INTEXTFILE%"
rename "%OUTTEXTFILE%" "%INTEXTFILE%"
endlocal

EDIT

Thanks David Nelson, I have updated the script so it doesn't have the hard coded values anymore.

Sample solution. Check, if this is what you need.

<div class="container">
   <div class="relative">      
      <div class="absolute"></div>      
      <div class="content">
        <p>
          Content here
        </p>
      </div>
    </div>
 </div>

And for CSS

.relative { 
  position: relative;
}

.absolute {
  position: absolute;
  top: 15px;
  left: 25px;   
}

You need to use the LINQ Dynamic Query Library in order to pass parameters at runtime,

This will allow linq statements like

string orderedBy = "Description";
var query = (from p in products
            orderby(orderedBy)
            select p);

df = pd.DataFrame(['-',3,2,5,1,-5,-1,'-',9])
df = df.where(df!='-', None)

You can do that in following way :
arr2 = arr1.map(x => Object.assign({}, x));

I made a librairy to make Hexadecimal / Decimal conversion without the use of stdio.h. Very simple to use :

char* dechex (int dec);

This will use calloc() to to return a pointer to an hexadecimal string, this way the quantity of memory used is optimized, so don't forget to use free()

Here the link on github : https://github.com/kevmuret/libhex/

To add to what Evan said: C does not have a built-in operator for exponentiation, because it is not a primitive operation for most CPUs. Thus, it's implemented as a library function.

Also, for computing the function e^x, you can use the exp(double), expf(float), and expl(long double) functions.

Note that you do not want to use the ^ operator, which is the bitwise exclusive OR operator.
