Programs & Examples On #Rational unified process

I think it's important to understand the intention of includes and extends:

"The include relationship is intended for reusing behaviour modeled by another use case, whereas the extend relationship is intended for adding parts to existing use cases as well as for modeling optional system services" (Overgaard and Palmkvist, Use Cases: Patterns and Blueprints. Addison-Wesley, 2004).

This reads to me as:

Include = reuse of functionality (i.e. the included functionality is used or could be used elsewhere in the system). Include therefore denotes a dependency on another use case.

Extends = adding (not reusing) functionality and also any optional functionality. Extends therefore can denote one of two things:
1. adding new features/capabilities to a use case (optional or not)
2. any optional use cases (existing or not).

Summary:
Include = reuse of functionality
Extends = new and/or optional functionality

You will most often find the 2nd usage (i.e. optional functionality) of extends, because if functionality is not optional, then most times it is built into the use case itself, rather than being an extension. At least that's been my experience. (Julian C points out that you sometimes see the 1st usage (i.e. adding new features) of extends when a project enters it's 2nd phase).

I had the same issue on OS X 10.9.1 with python 2.7.5. No issues with WORKON_HOME for me, but I did have to manually add source "/usr/local/bin/virtualenvwrapper.sh" to ~/.bash_profile (or ~/.bashrc in unix) after I ran pip install virtualenvwrapper

It depends where you put this initialisation.

If the array is static as in

char array[100] = {0};

int main(void)
{
...
}

then it is the compiler that reserves the 100 0 bytes in the data segement of the program. In this case you could have omitted the initialiser.

If your array is auto, then it is another story.

int foo(void)
{
char array[100] = {0};
...
}

In this case at every call of the function foo you will have a hidden memset.

The code above is equivalent to

int foo(void)
{ 
char array[100];

memset(array, 0, sizeof(array));
....
}

and if you omit the initializer your array will contain random data (the data of the stack).

If your local array is declared static like in

int foo(void)
{ 
static char array[100] = {0};
...
}

then it is technically the same case as the first one.

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.

F5 is a standard page reload.

and

Ctrl + F5 refreshes the page by clearing the cached content of the page.

Having the cursor in the address field and pressing Enter will also do the same as Ctrl + F5.

set "DIR_TO_DELETE=your_path_to_the_folder"

IF EXIST %DIR_TO_DELETE% (
    FOR /D %%p IN ("%DIR_TO_DELETE%\*.*") DO rmdir "%%p" /S /Q
    del %DIR_TO_DELETE%\*.* /F /Q
)

Hers's what I used to get the day names (0-6 means monday - sunday):

public static String getFullDayName(int day) {
    Calendar c = Calendar.getInstance();
    // date doesn't matter - it has to be a Monday
    // I new that first August 2011 is one ;-)
    c.set(2011, 7, 1, 0, 0, 0);
    c.add(Calendar.DAY_OF_MONTH, day);
    return String.format("%tA", c);
}

public static String getShortDayName(int day) {
    Calendar c = Calendar.getInstance();
    c.set(2011, 7, 1, 0, 0, 0);
    c.add(Calendar.DAY_OF_MONTH, day);
    return String.format("%ta", c);
}

You should check if it's not defined using if (!Array.prototype.indexOf).

Also, your implementation of indexOf is not correct. You must use === instead of == in your if (this[i] == obj) statement, otherwise [4,"5"].indexOf(5) would be 1 according to your implementation, which is incorrect.

I recommend you use the implementation on MDC.

you simply have to change the basic language of microsoft on your computer!

press the windows button together with r, and tip the following code into the window that is opened

control.exe /name Microsoft.Language

load the language package you want to use and change the options. but take care, this will change also your keyboard layout!

I created a function to handle this situation, thought I would share it.

getDirectDecendent(elem, selector, all){
    const tempID = randomString(10) //use your randomString function here.
    elem.dataset.tempid = tempID;

    let returnObj;
    if(all)
        returnObj = elem.parentElement.querySelectorAll(`[data-tempid="${tempID}"] > ${selector}`);
    else
        returnObj = elem.parentElement.querySelector(`[data-tempid="${tempID}"] > ${selector}`);

    elem.dataset.tempid = '';
    return returnObj;
}

In essence what you are doing is generating a random-string (randomString function here is an imported npm module, but you can make your own.) then using that random string to guarantee that you get the element you are expecting in the selector. Then you are free to use the > after that.

The reason I am not using the id attribute is that the id attribute may already be used and I don't want to override that.

In Python you can use (.)\1{9,}

• (.) makes group from one char (any char)
• \1{9,} matches nine or more characters from 1st group

example:

txt = """1. aaaaaaaaaaaaaaa
2. bb
3. cccccccccccccccccccc
4. dd
5. eeeeeeeeeeee"""
rx = re.compile(r'(.)\1{9,}')
lines = txt.split('\n')
for line in lines:
    rxx = rx.search(line)
    if rxx:
        print line

Output:

1. aaaaaaaaaaaaaaa
3. cccccccccccccccccccc
5. eeeeeeeeeeee

You can do this by comparing each field using the NULL-safe equals operator <=> and then negating the result using NOT.

The complete trigger would become:

DROP TRIGGER IF EXISTS `my_trigger_name`;

DELIMITER $$

CREATE TRIGGER `my_trigger_name` AFTER UPDATE ON `my_table_name` FOR EACH ROW 
    BEGIN
        /*Add any fields you want to compare here*/
        IF !(OLD.a <=> NEW.a AND OLD.b <=> NEW.b) THEN
            INSERT INTO `my_other_table` (
                `a`,
                 `b`
            ) VALUES (
                NEW.`a`,
                NEW.`b`
            );
        END IF;
    END;$$

DELIMITER ;

(Based on a different answer of mine.)

We can use the get_locale function:

if (get_locale() == 'en_GB') {
    // drink tea
}

Copyed the *.jar into my WEB-INF/lib folder -> Worked for me. When including over buildpath there was everytime this errormsg.

In Java terms, Scala's Seq would be Java's List, and Scala's List would be Java's LinkedList.

Note that Seq is a trait, which is equivalent to Java's interface, but with the equivalent of up-and-coming defender methods. Scala's List is an abstract class that is extended by Nil and ::, which are the concrete implementations of List.

So, where Java's List is an interface, Scala's List is an implementation.

Beyond that, Scala's List is immutable, which is not the case of LinkedList. In fact, Java has no equivalent to immutable collections (the read only thing only guarantees the new object cannot be changed, but you still can change the old one, and, therefore, the "read only" one).

Scala's List is highly optimized by compiler and libraries, and it's a fundamental data type in functional programming. However, it has limitations and it's inadequate for parallel programming. These days, Vector is a better choice than List, but habit is hard to break.

Seq is a good generalization for sequences, so if you program to interfaces, you should use that. Note that there are actually three of them: collection.Seq, collection.mutable.Seq and collection.immutable.Seq, and it is the latter one that is the "default" imported into scope.

There's also GenSeq and ParSeq. The latter methods run in parallel where possible, while the former is parent to both Seq and ParSeq, being a suitable generalization for when parallelism of a code doesn't matter. They are both relatively newly introduced, so people doesn't use them much yet.

Install msys2 with make dependency add both to PATH variable. (The second option is GNU ToolChain for Windows. MinGW version has already mingw32-make included.)

Install Git Bash. Run mingw32-make from Git Bash.

If installed Django using python setup.py install

Try the following command iptables-save.

As stated from David Cournapeau, use figure().

import matplotlib
import matplotlib.pyplot as plt
import matplotlib.mlab as mlab

plt.figure()
x = [1,10]
y = [30, 1000]
plt.loglog(x, y, basex=10, basey=10, ls="-")
plt.savefig("first.ps")


plt.figure()
x = [10,100]
y = [10, 10000]
plt.loglog(x, y, basex=10, basey=10, ls="-")
plt.savefig("second.ps")

Or subplot(121) / subplot(122) for the same plot, different position.

import matplotlib
import matplotlib.pyplot as plt
import matplotlib.mlab as mlab

plt.subplot(121)
x = [1,10]
y = [30, 1000]
plt.loglog(x, y, basex=10, basey=10, ls="-")

plt.subplot(122)
x = [10,100]
y = [10, 10000]
plt.loglog(x, y, basex=10, basey=10, ls="-")
plt.savefig("second.ps")

In my case (using webpack 4) within an anonymous function, that I was using as a callback.

I had to use window.$.ajax() instead of $.ajax() despite having:

import $ from 'jquery';
window.$ = window.jQuery = $;

Pillow is released with installation wheels on Windows:

We provide Pillow binaries for Windows compiled for the matrix of supported Pythons in both 32 and 64-bit versions in wheel, egg, and executable installers. These binaries have all of the optional libraries included

https://pillow.readthedocs.io/en/3.3.x/installation.html#basic-installation

Update: Python 3.6 is now supported by Pillow. Install with pip install pillow and check https://pillow.readthedocs.io/en/latest/installation.html for more information.

However, Python 3.6 is still in alpha and not officially supported yet, although the tests do all pass for the nightly Python builds (currently 3.6a4).

Failing that, downgrade to Python 3.5 or wait until 3.6 is supported by Pillow, probably closer to the 3.6's official release.

Interface is the class that contains an abstract method that cannot create any object.Since Interface cannot create the object and its not a pure class, Its no worth implementing it.

Create FUNCTION [dbo].[fnSplitString] 
( 
    @string NVARCHAR(200), 
    @delimiter CHAR(1) 
) 
RETURNS @output TABLE(splitdata NVARCHAR(10) 
) 
BEGIN 
    DECLARE @start INT, @end INT 
    SELECT @start = 1, @end = CHARINDEX(@delimiter, @string) 
    WHILE @start < LEN(@string) + 1 BEGIN 
        IF @end = 0  
            SET @end = LEN(@string) + 1

        INSERT INTO @output (splitdata)  
        VALUES(SUBSTRING(@string, @start, @end - @start)) 
        SET @start = @end + 1 
        SET @end = CHARINDEX(@delimiter, @string, @start)

    END 
    RETURN 

END**strong text**

Recommendation. Do not use user-added REM statements to block batch steps. Use conditional GOTO instead. That way you can predefine and test the steps and options. The users also get much simpler changes and better confidence.

@Echo on
rem Using flags to control command execution

SET ExecuteSection1=0
SET ExecuteSection2=1

@echo off

IF %ExecuteSection1%==0 GOTO EndSection1
ECHO Section 1 Here

:EndSection1

IF %ExecuteSection2%==0 GOTO EndSection2
ECHO Section 2 Here
:EndSection2

This should work:

start "" "c:\program files\php\php.exe" D:\mydocs\mp\index.php param1 param2

The start command interprets the first argument as a window title if it contains spaces. In this case, that means start considers your whole argument a title and sees no command. Passing "" (an empty title) as the first argument to start fixes the problem.

php curl lib is just a wrapper of cUrl, so, first of all, you should install cUrl. Download the cUrl source to your linux server. Then, use the follow commands to install:

tar zxvf cUrl_src_taz
cd cUrl_src_taz
./configure --prefix=/curl/install/home
make
make test    (optional)
make install
ln -s  /curl/install/home/bin/curl-config /usr/bin/curl-config

Then, copy the head files in the "/curl/install/home/include/" to "/usr/local/include". After all above steps done, the php curl extension configuration could find the original curl, and you can use the standard php extension method to install php curl.
Hope it helps you, :)

SELECT *

According to this article, you want a mod_rewrite (placed in an .htaccess file) rule that looks something like this:

RewriteEngine on
RewriteRule ^/news/([0-9]+)\.html /news.php?news_id=$1

And this maps requests from

/news.php?news_id=63

to

/news/63.html

Another possibility is doing it with forcetype, which forces anything down a particular path to use php to eval the content. So, in your .htaccess file, put the following:

<Files news>
    ForceType application/x-httpd-php
</Files>

And then the index.php can take action based on the $_SERVER['PATH_INFO'] variable:

<?php
    echo $_SERVER['PATH_INFO'];
    // outputs '/63.html'
?>

I faced this issue when I was tring to link a locally created repo with a blank repo on github. Initially I was trying git remote set-url but I had to do git remote add instead.

git remote add origin https://github.com/VijayNew/NewExample.git

Oldie but goldie...

Since user is asking for jQuery, I'm going to keep it simple:

var html = $('#container').clone();
console.log(html);

Fiddle here.

You can use wildcards with the del command, and /S to do it recursively.

del /S *.jpg

Addendum

@BmyGuest asked why a downvoted answer (del /s c:\*.blaawbg) was any different than my answer.

There's a huge difference between running del /S *.jpg and del /S C:\*.jpg. The first command is executed from the current location, whereas the second is executed on the whole drive.

In the scenario where you delete jpg files using the second command, some applications might stop working, and you'll end up losing all your family pictures. This is utterly annoying, but your computer will still be able to run.

However, if you are working on some project, and want to delete all your dll files in myProject\dll, and run the following batch file:

@echo off

REM This short script will only remove dlls from my project... or will it?

cd \myProject\dll
del /S /Q C:\*.dll

Then you end up removing all dll files form your C:\ drive. All of your applications stop working, your computer becomes useless, and at the next reboot you are teleported in the fourth dimension where you will be stuck for eternity.

The lesson here is not to run such command directly at the root of a drive (or in any other location that might be dangerous, such as %windir%) if you can avoid it. Always run them as locally as possible.

Addendum 2

The wildcard method will try to match all file names, in their 8.3 format, and their "long name" format. For example, *.dll will match project.dll and project.dllold, which can be surprising. See this answer on SU for more detailed information.

Cython

It seems that the goto answer for this is Cython. I'm really surprised no one else mentioned this yet? Here's the home page: https://cython.org

In a nutshell, this transforms your python into C and compiles it, thus making it as well protected as any "normal" compiled distributable C program.

There are limitations though. I haven't explored them in depth myself, because as I started to read about them, I dropped the idea for my own purposes. But it might still work for yours. Essentially, you can't use Python to the fullest, with the dynamic awesomeness it offers. One major issue that jumped out at me, was that keyword parameters are not usable :( You must write function calls using positional parameters only. I didn't confirm this, but I doubt you can use conditional imports, or evals. I'm not sure how polymorphism is handled...

Anyway, if you aren't trying to obfuscate a huge code base after the fact, or ideally if you have the use of Cython in mind to begin with, this is a very notable option.

What about something like this?

<?php
$URL = "http://example.com";
$base = '<base href="'.$URL.'">';
$host = preg_replace('/^[^\/]+\/\//', '', $URL);
$tarray = explode('/', $host);
$host = array_shift($tarray);
$URI = '/' . implode('/', $tarray);
$content = '';
$fp = @fsockopen($host, 80, $errno, $errstr, 30);
if(!$fp) { echo "Unable to open socked: $errstr ($errno)\n"; exit; } 
fwrite($fp,"GET $URI HTTP/1.0\r\n");
fwrite($fp,"Host: $host\r\n");
if( isset($_SERVER["HTTP_USER_AGENT"]) ) { fwrite($fp,'User-Agent: '.$_SERVER

["HTTP_USER_AGENT"]."\r\n"); }
fwrite($fp,"Connection: Close\r\n");
fwrite($fp,"\r\n");
while (!feof($fp)) { $content .= fgets($fp, 128); }
fclose($fp);
if( strpos($content,"\r\n") > 0 ) { $eolchar = "\r\n"; }
else { $eolchar = "\n"; }
$eolpos = strpos($content,"$eolchar$eolchar");
$content = substr($content,($eolpos + strlen("$eolchar$eolchar")));
if( preg_match('/<head\s*>/i',$content) ) { echo( preg_replace('/<head\s*>/i','<head>'.

$base,$content,1) ); }
else { echo( preg_replace('/<([a-z])([^>]+)>/i',"<\\1\\2>".$base,$content,1) ); }
?>

Params contains the following three groups of parameters:

1. User supplied parameters
   • GET (http://domain.com/url?param1=value1&param2=value2 will set params[:param1] and params[:param2])
   • POST (e.g. JSON, XML will automatically be parsed and stored in params)
   • Note: By default, Rails duplicates the user supplied parameters and stores them in params[:user] if in UsersController, can be changed with wrap_parameters setting
2. Routing parameters
   • match '/user/:id' in routes.rb will set params[:id]
3. Default parameters
   • params[:controller] and params[:action] is always available and contains the current controller and action

Some explanation ignore a condition about the retain cycle [If a group of objects is connected by a circle of strong relationships, they keep each other alive even if there are no strong references from outside the group.] For more information, read the document

Most proposed answers don't take into account a time-out interval, which is very important to prevent a possible deadlock. Next is my sample code. (Note that I'm primarily a Win32 developer, and that's how I'd do it there.)

//'arrRunningThreads' = List<Thread>

//Wait for all threads
const int knmsMaxWait = 3 * 1000;           //3 sec timeout
int nmsBeginTicks = Environment.TickCount;
foreach(Thread thrd in arrRunningThreads)
{
    //See time left
    int nmsElapsed = Environment.TickCount - nmsBeginTicks;
    int nmsRemain = knmsMaxWait - nmsElapsed;
    if(nmsRemain < 0)
        nmsRemain = 0;

    //Then wait for thread to exit
    if(!thrd.Join(nmsRemain))
    {
        //It didn't exit in time, terminate it
        thrd.Abort();

        //Issue a debugger warning
        Debug.Assert(false, "Terminated thread");
    }
}

I'm not sure there's a way to hide that information. No matter what you do to obfuscate or hide whatever you're doing in JavaScript, it still comes down to the fact that your browser needs to load it in order to use it. Modern browsers have web debugging/analysis tools out of the box that make extracting and viewing scripts trivial (just hit F12 in Chrome, for example).

If you're worried about exposing some kind of trade secret or algorithm, then your only recourse is to encapsulate that logic in a web service call and have your page invoke that functionality via AJAX.

Here is a working example with Angular version 2.3. Just call the constructor of the service the stand way like this constructor(private _userService:UserService) . And it will create a singleton for the app.

user.service.ts

import { Injectable } from '@angular/core';
import { Observable } from 'rxjs/Rx';
import { Subject }    from 'rxjs/Subject';
import { User } from '../object/user';


@Injectable()
export class UserService {
    private userChangedSource;
    public observableEvents;
    loggedUser:User;

    constructor() {
       this.userChangedSource = new Subject<any>();
       this.observableEvents = this.userChangedSource.asObservable();
    }

    userLoggedIn(user:User) {
        this.loggedUser = user;
        this.userChangedSource.next(user);
    }

    ...
}

app.component.ts

import { Component } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import { UserService } from '../service/user.service';
import { User } from '../object/user';

@Component({
    selector: 'myApp',
    templateUrl: './app.component.html'
})
export class AppComponent implements OnInit {
    loggedUser:User;

    constructor(private _userService:UserService) { 
        this._userService.observableEvents.subscribe(user => {
                this.loggedUser = user;
                console.log("event triggered");
        });
    }
    ...
}

folks, I got this Bootstrap dropdown working. I modified the click event slightly in order to keep the currently-selected image. And as you see, the USD currency is the default selected :

<div class="btn-group" style="margin:10px;">    <!-- CURRENCY, BOOTSTRAP DROPDOWN -->
                <!--<a class="btn btn-primary" href="javascript:void(0);">Currency</a>-->                    
                <a class="btn btn-primary dropdown-toggle" data-toggle="dropdown" href="#"><img src="../../Images/flag-usd-small.png"> USD <span class="caret"></span></a>
                <ul class="dropdown-menu">

                    </li>
                    <li><a href="javascript:void(0);">

My problem was fideloper proxy version.

when i upgraded laravel 5.5 to 5.8 this happened

just sharing if anybody get help

change you composer json fideloper version:

"fideloper/proxy": "^4.0",

After that you need to run update composer that's it.

composer update

A Subscription is an object that represents a disposable resource, usually the execution of an Observable. A Subscription has one important method, unsubscribe, that takes no argument and just disposes of the resource held by the subscription.

import { interval } from 'rxjs';

const observable = interval(1000);
const subscription = observable.subscribe(a=> console.log(a));

/** This cancels the ongoing Observable execution which
was started by calling subscribe with an Observer.*/

subscription.unsubscribe();

A Subscription essentially just has an unsubscribe() function to release resources or cancel Observable executions.

import { interval } from 'rxjs';

const observable1 = interval(400);
const observable2 = interval(300);

const subscription = observable1.subscribe(x => console.log('first: ' + x));
const childSubscription = observable2.subscribe(x => console.log('second: ' + x));

subscription.add(childSubscription);

setTimeout(() => {
// It unsubscribes BOTH subscription and childSubscription
subscription.unsubscribe();
}, 1000);

According to the official documentation, Angular should unsubscribe for you, but apparently, there is a bug.

In GitHub markdown <ins>text</ins>works just fine.

As an aside, when trying to diagnose a similar bug I realised that jquery's ajax error callback returns a status of "timeout" if it failed due to a timeout.

Here's an example:

$.ajax({
    url: "/ajax_json_echo/",
    timeout: 500,
    error: function(jqXHR, textStatus, errorThrown) {
        alert(textStatus); // this will be "timeout"
    }
});

Here it is on jsfiddle.

Yes, you can install an interrupt handler using the module signal, and wait forever using a threading.Event:

import signal
import sys
import time
import threading

def signal_handler(signal, frame):
    print('You pressed Ctrl+C!')
    sys.exit(0)

signal.signal(signal.SIGINT, signal_handler)
print('Press Ctrl+C')
forever = threading.Event()
forever.wait()

The voted up answer is missing a step.

Per aws s3 help:

Currently, there is no support for the use of UNIX style wildcards in a command's path arguments. However, most commands have --exclude "<value>" and --include "<value>" parameters that can achieve the desired result......... When there are multiple filters, the rule is the filters that appear later in the command take precedence over filters that appear earlier in the command. For example, if the filter parameters passed to the command were --exclude "*" --include "*.txt" All files will be excluded from the command except for files ending with .txt

aws s3 rm --recursive s3://bucket/ --exclude="*" --include="/folder_path/*" 

The best approach for you to communicate between the two controllers is to use events.

Scope Documentation

In this check out $on, $broadcast and $emit.

In general use case the usage of angular.element(catapp).scope() was designed for use outside the angular controllers, like within jquery events.

Ideally in your usage you would write an event in controller 1 as:

$scope.$on("myEvent", function (event, args) {
   $scope.rest_id = args.username;
   $scope.getMainCategories();
});

And in the second controller you'd just do

$scope.initRestId = function(){
   $scope.$broadcast("myEvent", {username: $scope.user.username });
};

Edit: Realised it was communication between two modules

Can you try including the firstApp module as a dependency to the secondApp where you declare the angular.module. That way you can communicate to the other app.

I got the error because of a clumsy typo:

This errors:

knitr::opts_chunk$seet(echo = FALSE)

Error: attempt to apply non-function

After correcting the typo, it works:

knitr::opts_chunk$set(echo = FALSE)

Generally speaking:

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

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

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

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

In your specific code samples:

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

if any(foobars) == big_foobar:

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

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

What you want instead is:

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

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

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

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

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

In [2]: big_foobar = 'big'                                                                          

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

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

Some examples:

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

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

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

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

SHOW FULL PROCESSLIST

If you don't use FULL, "only the first 100 characters of each statement are shown in the Info field".

When using phpMyAdmin, you should also click on the "Full texts" option ("? T ?" on top left corner of a results table) to see untruncated results.

DataTable dt = new DataTable();

SqlDataAdapter adapter = new SqlDataAdapter(cmd);

adapter.Fill(dt);

foreach(DataRow row in dt.Rows)
{
    TextBox1.Text = row["ImagePath"].ToString();
}

...assumes the connection is open and the command is set up properly. I also didn't check the syntax, but it should give you the idea.

conftest solution

The least invasive solution is adding an empty file named conftest.py in the repo/ directory:

$ touch repo/conftest.py

That's it. No need to write custom code for mangling the sys.path or remember to drag PYTHONPATH along, or placing __init__.py into dirs where it doesn't belong (using python -m pytest as suggested in Apteryx's answer is a good solution though!).

The project directory afterwards:

repo
+-- conftest.py
+-- app.py
+-- settings.py
+-- models.py
+-- tests
     +-- test_app.py

Explanation

pytest looks for the conftest modules on test collection to gather custom hooks and fixtures, and in order to import the custom objects from them, pytest adds the parent directory of the conftest.py to the sys.path (in this case the repo directory).

Other project structures

If you have other project structure, place the conftest.py in the package root dir (the one that contains packages but is not a package itself, so does not contain an __init__.py), for example:

repo
+-- conftest.py
+-- spam
¦   +-- __init__.py
¦   +-- bacon.py
¦   +-- egg.py
+-- eggs
¦   +-- __init__.py
¦   +-- sausage.py
+-- tests
     +-- test_bacon.py
     +-- test_egg.py

src layout

Although this approach can be used with the src layout (place conftest.py in the src dir):

repo
+-- src
¦   +-- conftest.py
¦   +-- spam
¦   ¦   +-- __init__.py
¦   ¦   +-- bacon.py
¦   ¦   +-- egg.py
¦   +-- eggs 
¦       +-- __init__.py
¦       +-- sausage.py
+-- tests
     +-- test_bacon.py
     +-- test_egg.py

beware that adding src to PYTHONPATH mitigates the meaning and benefits of the src layout! You will end up with testing the code from repository and not the installed package. If you need to do it, maybe you don't need the src dir at all.

Where to go from here

Of course, conftest modules are not just some files to help the source code discovery; it's where all the project-specific enhancements of the pytest framework and the customization of your test suite happen. pytest has a lot of information on conftest modules scattered throughout their docs; start with conftest.py: local per-directory plugins

Also, SO has an excellent question on conftest modules: In py.test, what is the use of conftest.py files?

overflow: auto (or overflow-y: auto) is the correct way to go.

The problem is that your text area is taller than your div. The div ends up cutting off the textbox, so even though it looks like it should start scrolling when the text is taller than 159px it won't start scrolling until the text is taller than 400px which is the height of the textbox.

Try this: http://jsfiddle.net/G9rfq/1/

I set overflow:auto on the text box, and made the textbox the same size as the div.

Also I don't believe it's valid to have a div inside a label, the browser will render it, but it might cause some funky stuff to happen. Also your div isn't closed.

I have just downloaded Tomcat and want to stop it (Windows).

1. To stop tomcat

   • run cmd as administrator (I used Cmder)

   • find process ID

tasklist /fi "Imagename eq tomcat*"

C:\Users\Admin
tasklist /fi "Imagename eq tomcat*"

Image Name                     PID Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
Tomcat8aaw.exe                6376 Console                    1      7,300 K
Tomcat8aa.exe                 5352 Services                   0    124,748 K

• stop prosess with pid 6376

C:\Users\Admin

taskkill /f /pid 6376

SUCCESS: The process with PID 6376 has been terminated.

• stop process with pid 5352

C:\Users\Admin

taskkill /f /pid 5352

SUCCESS: The process with PID 5352 has been terminated.

Sometimes you need to get HTTP headers but at the same time you don't want return those headers.**

This skeleton takes care of cookies and HTTP redirects using recursion. The main idea here is to avoid return HTTP headers to the client code.

You can build a very strong curl class over it. Add POST functionality, etc.

<?php

class curl {

  static private $cookie_file            = '';
  static private $user_agent             = '';  
  static private $max_redirects          = 10;  
  static private $followlocation_allowed = true;

  function __construct()
  {
    // set a file to store cookies
    self::$cookie_file = 'cookies.txt';

    // set some general User Agent
    self::$user_agent = 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)';

    if ( ! file_exists(self::$cookie_file) || ! is_writable(self::$cookie_file))
    {
      throw new Exception('Cookie file missing or not writable.');
    }

    // check for PHP settings that unfits
    // correct functioning of CURLOPT_FOLLOWLOCATION 
    if (ini_get('open_basedir') != '' || ini_get('safe_mode') == 'On')
    {
      self::$followlocation_allowed = false;
    }    
  }

  /**
   * Main method for GET requests
   * @param  string $url URI to get
   * @return string      request's body
   */
  static public function get($url)
  {
    $process = curl_init($url);    

    self::_set_basic_options($process);

    // this function is in charge of output request's body
    // so DO NOT include HTTP headers
    curl_setopt($process, CURLOPT_HEADER, 0);

    if (self::$followlocation_allowed)
    {
      // if PHP settings allow it use AUTOMATIC REDIRECTION
      curl_setopt($process, CURLOPT_FOLLOWLOCATION, true);
      curl_setopt($process, CURLOPT_MAXREDIRS, self::$max_redirects); 
    }
    else
    {
      curl_setopt($process, CURLOPT_FOLLOWLOCATION, false);
    }

    $return = curl_exec($process);

    if ($return === false)
    {
      throw new Exception('Curl error: ' . curl_error($process));
    }

    // test for redirection HTTP codes
    $code = curl_getinfo($process, CURLINFO_HTTP_CODE);
    if ($code == 301 || $code == 302)
    {
      curl_close($process);

      try
      {
        // go to extract new Location URI
        $location = self::_parse_redirection_header($url);
      }
      catch (Exception $e)
      {
        throw $e;
      }

      // IMPORTANT return 
      return self::get($location);
    }

    curl_close($process);

    return $return;
  }

  static function _set_basic_options($process)
  {

    curl_setopt($process, CURLOPT_USERAGENT, self::$user_agent);
    curl_setopt($process, CURLOPT_COOKIEFILE, self::$cookie_file);
    curl_setopt($process, CURLOPT_COOKIEJAR, self::$cookie_file);
    curl_setopt($process, CURLOPT_RETURNTRANSFER, 1);
    // curl_setopt($process, CURLOPT_VERBOSE, 1);
    // curl_setopt($process, CURLOPT_SSL_VERIFYHOST, false);
    // curl_setopt($process, CURLOPT_SSL_VERIFYPEER, false);
  }

  static function _parse_redirection_header($url)
  {
    $process = curl_init($url);    

    self::_set_basic_options($process);

    // NOW we need to parse HTTP headers
    curl_setopt($process, CURLOPT_HEADER, 1);

    $return = curl_exec($process);

    if ($return === false)
    {
      throw new Exception('Curl error: ' . curl_error($process));
    }

    curl_close($process);

    if ( ! preg_match('#Location: (.*)#', $return, $location))
    {
      throw new Exception('No Location found');
    }

    if (self::$max_redirects-- <= 0)
    {
      throw new Exception('Max redirections reached trying to get: ' . $url);
    }

    return trim($location[1]);
  }

}

Apart from the above solutions,there is another way we can achieve .

    decimal val=23.5678m,finalValue;

    //take the decimal part    
     int decimalPos = val.ToString().IndexOf('.');
     string decimalPart = val.ToString().Substring(decimalPosition+1,val.ToString().Length);
    //will result.56
   string wholePart=val.ToString().Substring(0,decimalPos-1);
   //concantinate and parse for decimal.
  string truncatedValue=wholePart+decimalPart;//"23.56"
  bool isDecimal=Decimal.tryParse(truncatedValue,out finalValue);//finalValue=23.56

To check if a String is alphanumeric, you can use a method that goes through every character in the string and checks if it is alphanumeric.

    public static boolean isAlphaNumeric(String s){
            for(int i = 0; i < s.length(); i++){
                    char c = s.charAt(i);
                    if(!Character.isDigit(c) && !Character.isLetter(c))
                            return false;
            }
            return true;
    }

' \r ' means carriage return.

The \r means nothing special as a consequence.For character-mode terminals (typically emulating even-older printing ones as above), in raw mode, \r and \n act similarly (except both in terms of the cursor, as there is no carriage or roller . Historically a \n was used to move the carriage down, while the \r was used to move the carriage back to the left side of the screen.

In addition to the other responses:

Once obtained, Access Tokens are typically sent along with every request from Clients to protected Resource Servers. This induce a risk for access token stealing and replay (assuming of course that access tokens are of type "Bearer" (as defined in the initial RFC6750).

Examples of those risks, in real life:

• Resource Servers generally are distributed application servers and typically have lower security levels compared to Authorization Servers (lower SSL/TLS config, less hardening, etc.). Authorization Servers on the other hand are usually considered as critical Security infrastructure and are subject to more severe hardening.

• Access Tokens may show up in HTTP traces, logs, etc. that are collected legitimately for diagnostic purposes on the Resource Servers or clients. Those traces can be exchanged over public or semi-public places (bug tracers, service-desk, etc.).

• Backend RS applications can be outsourced to more or less trustworthy third-parties.

The Refresh Token, on the other hand, is typically transmitted only twice over the wires, and always between the client and the Authorization Server: once when obtained by client, and once when used by client during refresh (effectively "expiring" the previous refresh token). This is a drastically limited opportunity for interception and replay.

Last thought, Refresh Tokens offer very little protection, if any, against compromised clients.

Very simple, as pictured in the recv.

To check that you will want to read 1 byte from the socket with MSG_PEEK and MSG_DONT_WAIT. This will not dequeue data (PEEK) and the operation is nonblocking (DONT_WAIT)

while (recv(client->socket,NULL,1, MSG_PEEK | MSG_DONTWAIT) != 0) {
    sleep(rand() % 2); // Sleep for a bit to avoid spam
    fflush(stdin);
    printf("I am alive: %d\n", socket);
}

// When the client has disconnected, this line will execute
printf("Client %d went away :(\n", client->socket);

Found the example here.

Pretty old question but the most simple answer isn't yet posted.
Here it is :
1) In [workspace]\.metadata\.plugins\org.eclipse.e4.workbench delete workbench.xmi file.
In most cases it's enough - try to load Eclipse.
Still you have to re-configure your specific perspective settings (if any)

2) Now getting problems with building projects that worked perfectly? As of my experience following steps help:
- uncheck Projects->Build automatically
- switch to Java perspective (if not yet): Window -> Open perspective -> Java
- locate Problems view or open it: Window -> Show view -> Problems
- right-click on problem groups and select Delete. Be sure to delete Lint errors
- clean the workspace: Project -> Clean... with option Clean all projects
- check Projects->Build automatically
- if problems persist for some projects: right-click project, select Properties -> Android and make sure appropriate Project Build Target is chosen

3) It was always sufficient for me. But if you still get problems - try @george post recommendations

For MYSQL

ALTER TABLE myTable MODIFY myColumn {DataType} NULL

SQL Server and .Net Data Type mapping

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

You use css to change the opacity. To cope with IE you'd need something like:

.opaque {
    opacity : 0.3;
    -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=30)";
    filter: alpha(opacity=30);
}

But the only problem with this is that it means anything inside the container will also be 0.3 opacity. Thus you'll have to change your HTML to have another container, not inside the transparent one, that holds your content.

Otherwise the png technique, would work. Except you'd need a fix for IE6, which in itself could cause problems.

JavaScript running in a browser doesn't generally have access to the local file system. That's outside the sandbox. So I think the answer is no.

array = [1,2,3,4,5]
def square(array):
    result = map(lambda x: x * x,array)
    return list(result)
print(square(array))

You may want to unit test the initialization - but because it's in the OnStart method this is near to impossible. I would suggest moving the initialization code out into a separate class so that it can be tested or at least re-used in a form tester.

Secondly to add some logging (using Log4Net or similar) and add some verbose logging so that you can see details about runtime errors. Examples of runtime errors would be AccessViolation etc. especially if your service is running without enough privileges to access the config files.

I would add another column on the data sheet with equation =month(A2), then run the countif on that column... If you still wanted to use text month('APRIL'), you would need a lookup table to reference the name to the month number. Otherwise, just use 4 instead of April on your metric sheet.

You may try this example:

<form>_x000D_
  <h1>Hello! I'm duke! What's you name?</h1>_x000D_
  <input type="text" name="user">_x000D_
  <br>_x000D_
  <br>_x000D_
  <input type="submit" value="submit">&nbsp;&nbsp;&nbsp;&nbsp;_x000D_
  <input type="reset">_x000D_
</form>_x000D_
<h1>Hello ${param.user}</h1> _x000D_
<!-- its Expression Language -->

This can be accomplished with a simple VBA function. Excel has support for a Worksheet Change Sub which can be programmed to put a date in a related column every time it fires.

Private Sub Worksheet_Change(ByVal Target As Range)
    If Target.Column = 2 And Target.Offset(0, 3).Value = "" Then
        Target.Offset(0, 3) = Format(Now(), "HH:MM:SS")
    End If
End Sub

A quick explanation. The following "if" statement checks for two things: (1) if it is the second column that changed (Column B), and (2) if the cell 3 columns over (Column E) is currently empty.

If Target.Column = 2 And Target.Offset(0, 3).Value = "" Then

If both conditions are true, then it puts the date into the cell in Column E with the NOW() function.

Target.Offset(0, 3) = Format(Now(), "HH:MM:SS")

Range.Offset

Range.Column

Another option of course is to use Javascript (Jquery here):

$('.box1,.box2').each(function(){
    $(this).height($(this).parent().height());
})

in XAMPP the default root is "htdocs" inside the XAMPP folder, if you followed the instructions on the xampp homepage it would be "/opt/lampp/htdocs"

If you explicitly setPreferredSize(new Dimension(X, Y)); then it is better to use:

setLocation(dim.width/2-this.getPreferredSize().width/2, dim.height/2-this.getPreferredSize().height/2);

[Joke mode on]

You can fix this by adding this:

https://github.com/donavon/undefined-is-a-function

import { undefined } from 'undefined-is-a-function';
// Fixed! undefined is now a function.

[joke mode off]

Other answers have focused more on the multithreading vs multiprocessing aspect, but in python Global Interpreter Lock (GIL) has to be taken into account. When more number (say k) of threads are created, generally they will not increase the performance by k times, as it will still be running as a single threaded application. GIL is a global lock which locks everything out and allows only single thread execution utilizing only a single core. The performance does increase in places where C extensions like numpy, Network, I/O are being used, where a lot of background work is done and GIL is released.
So when threading is used, there is only a single operating system level thread while python creates pseudo-threads which are completely managed by threading itself but are essentially running as a single process. Preemption takes place between these pseudo threads. If the CPU runs at maximum capacity, you may want to switch to multiprocessing.
Now in case of self-contained instances of execution, you can instead opt for pool. But in case of overlapping data, where you may want processes communicating you should use multiprocessing.Process.

Here is how I solved the "slow symbol loading" problem in Visual Studio 2012:

• Go to Tools -> Options -> Debugging -> General

• CHECK the checkmark next to "Enable Just My Code".

• Go to Tools -> Options -> Debugging -> Symbols

• Click on the "..." button and create/select a new folder somewhere on your local computer to store cached symbols. I named mine "Symbol caching" and put it in Documents -> Visual Studio 2012.

• Click on "Load all symbols" and wait for the symbols to be downloaded from Microsoft's servers, which may take a while. Note that Load all symbols button is only available while debugging.

• UNCHECK the checkmark next to "Microsoft Symbol Servers" to prevent Visual Studio from remotely querying the Microsoft servers.

• Click "OK".

From now on, symbol loading should be much faster.

Note that if you make any changes/downloads to Microsoft assemblies, you may need to go back into the Symbols dialog box and "Load all symbols" again.

Try this through random.shuffle

>>> import random
>>> nums = range(10)
>>> random.shuffle(nums)
>>> nums
[6, 3, 5, 4, 0, 1, 2, 9, 8, 7]

Your code works, but the fadeIn doesn't, because it's already visible. I think the effect you want to achieve is: fadeOut → load → fadeIn:

var auto_refresh = setInterval(function () {
    $('.View').fadeOut('slow', function() {
        $(this).load('/echo/json/', function() {
            $(this).fadeIn('slow');
        });
    });
}, 15000); // refresh every 15000 milliseconds

Try it here: http://jsfiddle.net/kelunik/3qfNn/1/

Additional notice: As Khanh TO mentioned, you may need to get rid of the browser's internal cache. You can do so using $.ajax and $.ajaxSetup ({ cache: false }); or the random-hack, he mentioned.

yu have to install the correct version for your computer 32 or 63 bits thats all

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

If you want to use something that is more descriptive than a dumb array without resorting to using a DataSet then the following might prove useful. It still isn't strongly-typed, but at least it is checked by the compiler and will handle being refactored quite well.

Dim previousAllowUserToAddRows = dgvHistoricalInfo.AllowUserToAddRows
dgvHistoricalInfo.AllowUserToAddRows = True

Dim newTimeRecord As DataGridViewRow = dgvHistoricalInfo.Rows(dgvHistoricalInfo.NewRowIndex).Clone

With record
    newTimeRecord.Cells(dgvcDate.Index).Value = .Date
    newTimeRecord.Cells(dgvcHours.Index).Value = .Hours
    newTimeRecord.Cells(dgvcRemarks.Index).Value = .Remarks
End With

dgvHistoricalInfo.Rows.Add(newTimeRecord)

dgvHistoricalInfo.AllowUserToAddRows = previousAllowUserToAddRows

It is worth noting that the user must have AllowUserToAddRows permission or this won't work. That is why I store the existing value, set it to true, do my work, and then reset it to how it was.

Maybe it is too simplistic, but I used this solution and I find it very useful when I have a primary key that I can use to compare data sets. Hope it can help.

a1 <- data.frame(a = 1:5, b = letters[1:5])
a2 <- data.frame(a = 1:3, b = letters[1:3])
different.names <- (!a1$a %in% a2$a)
not.in.a2 <- a1[different.names,]

Much easier solution:

Use the poppler-utils package. To install it use homebrew (homebrew is MacOS specific, but you can find the poppler-utils package for Widows or Linux here: https://poppler.freedesktop.org/). First line of code below installs poppler-utils using homebrew. After installation the second line (run from the command line) then extracts images from a PDF file and names them "image*". To run this program from within Python use the os or subprocess module. Third line is code using os module, beneath that is an example with subprocess (python 3.5 or later for run() function). More info here: https://www.cyberciti.biz/faq/easily-extract-images-from-pdf-file/

brew install poppler

pdfimages file.pdf image

import os
os.system('pdfimages file.pdf image')

or

import subprocess
subprocess.run('pdfimages file.pdf image', shell=True)

class Dependency{
  public void method(){};
}

public abstract class My {

  public void myNonAbstractMethod() {
    // ...
    dependency.method();
  }
}

@RunWith(MockitoJUnitRunner.class)
public class MyTest {

  @InjectMocks

In linux if you use code . it will open VS Code in the folder the terminal was in. Using code . Filename.cs it will open in folder and open said file.

For people reading this that use Angular 2 rc4 or later, it appears LocationStrategy has been moved from router to common. You'll have to import it from there.

Also note the curly brackets around the 'provide' line.

main.ts

// Imports for loading & configuring the in-memory web api
import { XHRBackend } from '@angular/http';

// The usual bootstrapping imports
import { bootstrap }      from '@angular/platform-browser-dynamic';
import { HTTP_PROVIDERS } from '@angular/http';

import { AppComponent }         from './app.component';
import { APP_ROUTER_PROVIDERS } from './app.routes';
import { Location, LocationStrategy, HashLocationStrategy} from '@angular/common';

bootstrap(AppComponent, [
    APP_ROUTER_PROVIDERS,
    HTTP_PROVIDERS,
    {provide: LocationStrategy, useClass: HashLocationStrategy}
]);

I have a simple script I use for this:

me@mycomputer:~$ cat /usr/local/bin/c

#!/bin/sh

echo "$*" | sed 's/x/\*/g' | bc -l

It changes x to * since * is a special character in the shell. Use it as follows:

• c 5x5
• c 5-4.2 + 1
• c '(5 + 5) * 30' (you still have to use quotes if the expression contains any parentheses).

The documentation has the complete answer. Anyway this is how it is done:

<input type="text" ng-model="filterValue">
<li ng-repeat="i in data | filter:{age:filterValue}:true"> {{i | json }}</li>

will filter only age in data array and true is for exact match.

For deep filtering,

<li ng-repeat="i in data | filter:{$:filterValue}:true"> {{i}}</li>

The $ is a special property for deep filter and the true is for exact match like above.

It is printing the statement twice because it is printing it for both the parent and the child. The parent has a parent id of 0

Try something like this:

 pid_t  pid;
 pid = fork();
 if (pid == 0) 
    printf("This is the child process. My pid is %d and my parent's id is %d.\n", getpid(),getppid());
 else 
    printf("This is the parent process. My pid is %d and my parent's id is %d.\n", getpid(), getppid() );

For any number validation you have to use different different range validation as per your requirements :

For Integer

[Range(0, int.MaxValue, ErrorMessage = "Please enter valid integer Number")]

for float

[Range(0, float.MaxValue, ErrorMessage = "Please enter valid float Number")]

for double

[Range(0, double.MaxValue, ErrorMessage = "Please enter valid doubleNumber")]

I think I have the solution to your question, assuming you can use flexbox in your project. What you want to do is make #one a flexbox using display: flex and use flex-direction: column to make it a column alignment.

The posts here help me a lot on my way to find a solution for the Uncaught TypeError: Cannot read property 'value' of undefined issue.

There are already here many answers which are correct, but what we don't have here is the combination for 2 answers that i think resolve this issue completely.

function myFunction(field, data){
  if (typeof document.getElementsByName("+field+")[0] != 'undefined'){
  document.getElementsByName("+field+")[0].value=data;
 }
}

The difference is that you make a check(if a property is defined or not) and if the check is true then you can try to assign it a value.

Minizip does have an example programs to demonstrate its usage - the files are called minizip.c and miniunz.c.

Update: I had a few minutes so I whipped up this quick, bare bones example for you. It's very smelly C, and I wouldn't use it without major improvements. Hopefully it's enough to get you going for now.

I built and tested it with MinGW/MSYS on Windows like this:

contrib/minizip/$ gcc -I../.. -o unzip uzip.c unzip.c ioapi.c ../../libz.a
contrib/minizip/$ ./unzip.exe /j/zlib-125.zip

#printing the variable 'Total:' in a format that looks like this '9,348.237'

print ('Total:',   '{:7,.3f}'.format(zum1))

where the '{:7,.3f}' es the number of spaces for formatting the number in this case is a million with 3 decimal points. Then you add the '.format(zum1). The zum1 is tha variable that has the big number for the sum of all number in my particular program. Variable can be anything that you decide to use.

The benefit of WireShark is that it could possibly show you errors in levels below the HTTP protocol. Fiddler will show you errors in the HTTP protocol.

If you think the problem is somewhere in the HTTP request issued by the browser, or you are just looking for more information in regards to what the server is responding with, or how long it is taking to respond, Fiddler should do.

If you suspect something may be wrong in the TCP/IP protocol used by your browser and the server (or in other layers below that), go with WireShark.

Just a quick answer to run your container using:

docker exec -it <container name> /bin/bash

once the container is open:

cd ..

then

`cd etc`

and then you can

cat hosts

or:

apt-get update
apt-get vim

or any editor you like and open it in vim, here you can modify say your startup ip to 0.0.0.0

See the documentation on ?merge, which states:

By default the data frames are merged on the columns with names they both have, 
 but separate specifications of the columns can be given by by.x and by.y.

This clearly implies that merge will merge data frames based on more than one column. From the final example given in the documentation:

x <- data.frame(k1=c(NA,NA,3,4,5), k2=c(1,NA,NA,4,5), data=1:5)
y <- data.frame(k1=c(NA,2,NA,4,5), k2=c(NA,NA,3,4,5), data=1:5)
merge(x, y, by=c("k1","k2")) # NA's match

This example was meant to demonstrate the use of incomparables, but it illustrates merging using multiple columns as well. You can also specify separate columns in each of x and y using by.x and by.y.

You can use json like the following example.

PHP code:

echo json_encode($array);

$array is array data, and the jQuery code is:

$.get("period/education/ajaxschoollist.php?schoolid="+schoolid, function(responseTxt, statusTxt, xhr){
    var a = JSON.parse(responseTxt);
    $("#hideschoolid").val(a.schoolid);
    $("#section_id").val(a.section_id);
    $("#schoolname").val(a.schoolname);
    $("#country_id").val(a.country_id);
    $("#state_id").val(a.state_id);
}

You can (but no longer should - see below!) use android.text.format.Time:

Time now = new Time();
now.setToNow();

From the reference linked above:

The Time class is a faster replacement for the java.util.Calendar and java.util.GregorianCalendar classes. An instance of the Time class represents a moment in time, specified with second precision.

NOTE 1: It's been several years since I wrote this answer, and it is about an old, Android-specific and now deprecated class. Google now says that "[t]his class has a number of issues and it is recommended that GregorianCalendar is used instead".

NOTE 2: Even though the Time class has a toMillis(ignoreDaylightSavings) method, this is merely a convenience to pass to methods that expect time in milliseconds. The time value is only precise to one second; the milliseconds portion is always 000. If in a loop you do

Time time = new Time();   time.setToNow();
Log.d("TIME TEST", Long.toString(time.toMillis(false)));
... do something that takes more than one millisecond, but less than one second ...

The resulting sequence will repeat the same value, such as 1410543204000, until the next second has started, at which time 1410543205000 will begin to repeat.

Check the default superclass's constructor. It need be public or protected.

In addition to this, due to some recent website hacks we had to secure our sites more. In doing so, we discovered that file_get_contents failed to work, where curl still would work.

Not 100%, but I believe that this php.ini setting may have been blocking the file_get_contents request.

; Disable allow_url_fopen for security reasons
allow_url_fopen = 0

Either way, our code now works with curl.

A standard approach is to add a clearing div between the two floating block level elements:

<div style="clear:both;"></div>

%lld is the standard C99 way, but that doesn't work on the compiler that I'm using (mingw32-gcc v4.6.0). The way to do it on this compiler is: %I64d

So try this:

if(e%n==0)printf("%15I64d -> %1.16I64d\n",e, 4*pi);

and

scanf("%I64d", &n);

The only way I know of for doing this in a completely portable way is to use the defines in <inttypes.h>.

In your case, it would look like this:

scanf("%"SCNd64"", &n);
//...    
if(e%n==0)printf("%15"PRId64" -> %1.16"PRId64"\n",e, 4*pi);

It really is very ugly... but at least it is portable.

From the two linksResolved Successfully and Naming Convention, I easily solved this same problem which I faced. i.e., for the foreign key name, give as fk_colName_TableName. This naming convention is non-ambiguous and also makes every ForeignKey in your DB Model unique and you will never get this error.

Error 1022: Can't write; duplicate key in table

The part you're missing is converting from the integer to the type-safe enum. Java will not do it automatically. There's a couple of ways you can go about this:

1. Use a list of static final ints rather than a type-safe enum and switch on the int value you receive (this is the pre-Java 5 approach)
2. Switch on either a specified id value (as described by heneryville) or the ordinal value of the enum values; i.e. guideView.GUIDE_VIEW_SEVEN_DAY.ordinal()

3. Determine the enum value represented by the int value and then switch on the enum value.

   enum GuideView {
       SEVEN_DAY,
       NOW_SHOWING,
       ALL_TIMESLOTS
   }
   
   // Working on the assumption that your int value is 
   // the ordinal value of the items in your enum
   public void onClick(DialogInterface dialog, int which) {
       // do your own bounds checking
       GuideView whichView = GuideView.values()[which];
       switch (whichView) {
           case SEVEN_DAY:
               ...
               break;
           case NOW_SHOWING:
               ...
               break;
       }
   }
   

   You may find it more helpful / less error prone to write a custom valueOf implementation that takes your integer values as an argument to resolve the appropriate enum value and lets you centralize your bounds checking.

I use a package.json for my packages and a config.js for my configuration, which looks like:

var config = {};

config.twitter = {};
config.redis = {};
config.web = {};

config.default_stuff =  ['red','green','blue','apple','yellow','orange','politics'];
config.twitter.user_name = process.env.TWITTER_USER || 'username';
config.twitter.password=  process.env.TWITTER_PASSWORD || 'password';
config.redis.uri = process.env.DUOSTACK_DB_REDIS;
config.redis.host = 'hostname';
config.redis.port = 6379;
config.web.port = process.env.WEB_PORT || 9980;

module.exports = config;

I load the config from my project:

var config = require('./config');

and then I can access my things from config.db_host, config.db_port, etc... This lets me either use hardcoded parameters, or parameters stored in environmental variables if I don't want to store passwords in source control.

I also generate a package.json and insert a dependencies section:

"dependencies": {
  "cradle": "0.5.5",
  "jade": "0.10.4",
  "redis": "0.5.11",
  "socket.io": "0.6.16",
  "twitter-node": "0.0.2",
  "express": "2.2.0"
}

When I clone the project to my local machine, I run npm install to install the packages. More info on that here.

The project is stored in GitHub, with remotes added for my production server.

"Dino TW" has provided the link to the comment Hibernate Mapping Exception : Repeated column in mapping for entity which has the vital information.

The link hints to provide "inverse=true" in the set mapping, I tried it and it actually works. It is such a rare situation wherein a Set and Composite key come together. Make inverse=true, we leave the insert & update of the table with Composite key to be taken care by itself.

Below can be the required mapping,

<class name="com.example.CompanyEntity" table="COMPANY">
    <id name="id" column="COMPANY_ID"/>
    <set name="names" inverse="true" table="COMPANY_NAME" cascade="all-delete-orphan" fetch="join" batch-size="1" lazy="false">
        <key column="COMPANY_ID" not-null="true"/>
        <one-to-many entity-name="vendorName"/>
    </set>
</class>

>>> some_string='A,B,C,D,E'
>>> new_tuple= tuple(some_string.split(','))
>>> new_tuple
('A', 'B', 'C', 'D', 'E')

In jquery set focus

$(function() {
  $("#txtBox1").focus();
});

or in Javascript you can do

window.onload = function() {
  document.getElementById("txtBox1").focus();
};

you should use position: relative; for one iframe and position:absolute; for the second;

Example: for first iframe use:

<div id="contentframe" style="position:relative; top: 100px; left: 50px;">

for second iframe use:

<div id="contentframe" style="position:absolute; top: 0px; left: 690px;">

I imagine that you define your image something like this:

<img id="image_portrait" src="" alt="chef etat"  width="120" height="135"  />

You can simply load/update image for this tag and chage/set atts (width,height):

var imagelink;
var height;
var width;
$("#image_portrait").attr("src", imagelink);
$("#image_portrait").attr("width", width);
$("#image_portrait").attr("height", height);

Coming late to the party, but I found this fantastic step-by-step guide on getting control of your SQLExpress instance if you don't have your sa password. I used this process to not only reset my sa password, but I also added my domain account to all the available server roles. I can now create databases, alter logins, do bulk operations, backups/restores, etc using my normal login.

To summarize, you use SQL Server Configuration Manager to put your instance into single-user mode. This elevates you to sysadmin when you connect, allowing you the ability to set everything up.

Edit: I've copied the steps below - kudos to the original author of the link above.

1. Log on to the computer as an Administrator (or Any user with administrator privileges)
2. Open "SQL Server Configuration Manager"
3. Click "SQL Server Services" on the left pane
4. Stop "SQL Server" and "SQL Server Agent" instance on the right pane if it is running
5. Run the SQL Express in single-user mode by right clicking on "SQL Server" instance -> Properties (on the right pane of SQL Server Configuration Manager).
6. Click Advanced Tab, and look for "Startup Parameters". Change the "Startup Parameters" so that the new value will be -m; (without the <>) example: from: -dc:\Program Files\Microsoft SQL.............(til end of string) to: -m;-dc:\Program Files\Microsoft SQL.............(til end of string)
7. Start the SQL Server
8. Open your MS SQL Server Management Studio and log on to the SQL server with "Windows Authentication" as the authentication mode. Since we have the SQL Server running on single user mode, and you are logged on to the computer with Administrator privileges, you will have a "sysadmin" access to the database.
9. Expand the "Security" node on MS SQL Server Management Studio on the left pane
10. Expand the "Logins" node
11. Double-click the 'sa' login
12. Change the password by entering a complex password if "Enforce password policy" is ticked, otherwise, just enter any password.
13. Make sure that "sa" Account is "enabled" by clicking on Status on the left pane. Set the radio box under "Login" to "Enabled"
14. Click "OK"
15. Back on the main window of MS SQL Server Management Studio, verify if SQL Server Authentication is used by right clicking on the top most node in the left pane (usually ".\SQLEXPRESS (SQL Server )") and choosing properties.
16. Click "Security" in the left pane and ensure that "SQL Server and Windows Authentication mode" is the one selected under "Server authentication"
17. Click "OK"
18. Disconnect from MS SQL Server Management Studio
19. Open "Sql Server Configuration Manager" again and stop the SQL Server instance.
20. Right-click on SQL Server instance and click on "Advanced" tab. Again look for "Startup Parameters" and remove the "-m;" that you added earlier.
21. Click "OK" and start the SQL Server Instance again
22. You should now be able to log on as "sa" using the new password that you have set in step 12.

lucky i find a solution. you can

import { ChangeEvent } from 'react';

and then write code like: e:ChangeEvent<HTMLInputElement>

Try this:

CREATE TABLE SCHEMA.NEW_TB LIKE SCHEMA.OLD_TB;
INSERT INTO SCHEMA.NEW_TB (SELECT * FROM SCHEMA.OLD_TB);

Options that are not copied include:

• Check constraints
• Column default values
• Column comments
• Foreign keys
• Logged and compact option on BLOB columns
• Distinct types

The only visible result I was able to understand was first to connect with the user I wanted to get the rights, then with the following query:

SELECT GRANTEE, PRIVILEGE, TABLE_NAME FROM USER_TAB_PRIVS;

Just do:

brew install python
brew link python

After doing that, add this to your bashrc or bash_profile:

alias python='/usr/local/bin/python2'

Enjoy!

For me issue with 'DOMAIN\MACHINENAME$' fixed by setting DefaultApplicationPool Identity to NetworkService.

Thunderbird supports html-body: mailto:[email protected]?subject=Me&html-body=<b>ME</b>

You could try something like the following:

a = [1,2,3,4,5]
# => [1, 2, 3, 4, 5]
(a.sum/a.length).to_f
# => 3.0

Try this:

<script type="text/javascript">

function test()
{
    if($('input#field').length==0)
    {
       $('<input type="button" id="field"/>').appendTo('body');
     }
}
</script>

According to python docs:

has_key() is deprecated in favor of key in d.

I think it is considered "more pythonic" to just use in when determining if a key already exists, as in

if start not in graph:
    return None

You cant add add items in string array more than its size, i'll suggest you to use ArrayList you can add items dynamically at run time in arrayList if you feel any problem you can freely ask

Here's a solution where security checking is disabled (for example, conversing with the localhost) Also, some of the solutions I've seen now contain deprecated methods and such.

Here's an implementation using node-http-proxy from nodejitsu.

var http = require('http');
var httpProxy = require('http-proxy');
var proxy = httpProxy.createProxyServer({});

http.createServer(function(req, res) {
    proxy.web(req, res, { target: 'http://www.google.com' });
}).listen(3000);

Consider the partial map.cshtml at Partials/Map.cshtml. This can be called from the Page where the partial is to be rendered, simply by using the <partial> tag:

<partial name="Partials/Map" model="new Pages.Partials.MapModel()" />

This is one of the easiest methods I encountered (although I am using razor pages, I am sure same is for MVC too)

If that's all what you want to do, you don't need to convert it into an array. You can just access it as:

string myData=yourDataTable.Rows[0][1].ToString();//Gives you USA

It depends on the context. I think you're referring to the operating system's hostname (returned by hostname when you're logged in). This command is for internal names only, so to query for a machine's name requires different naming systems. There are multiple systems which use names to identify hosts including DNS, DHCP, LDAP (DN's), hostname, etc. and many systems use zeroconf to synchronize names between multiple naming systems. For this reason, results from hostname will sometimes match results from dig (see below) or other naming systems, but often times they will not match.

DNS is by far the most common and is used both on the internet (like google.com. A 216.58.218.142) and at home (mDNS/LLMNR), so here's how to perform a reverse DNS lookup: dig -x <address> (nslookup and host are simpler, provide less detail, and may even return different results; however, dig is not included in Windows).

Note that hostnames within a CDN will not resolve to the canonical domain name (e.g. "google.com"), but rather the hostname of the host IP you queried (e.g. "dfw25s08-in-f142.1e100.net"; interesting tidbit: 1e100 is 1 googol).

Also note that DNS hosts can have more than one name. This is common for hosts with more than one webserver (virtual hosting), although this is becoming less common thanks to the proliferation of virtualization technologies. These hosts have multiple PTR DNS records.

Finally, note that DNS host records can be overridden by the local machine via /etc/hosts. If you're not getting the hostname you expect, be sure you check this file.

DHCP hostnames are queried differently depending on which DHCP server software is used, because (as far as I know) the protocol does not define a method for querying; however, most servers provide some way of doing this (usually with a privileged account).

Note DHCP names are usually synchronized with DNS server(s), so it's common to see the same hostnames in a DHCP client least table and in the DNS server's A (or AAAA for IPv6) records. Again, this is usually done as part of zeroconf.

Also note that just because a DHCP lease exists for a client, doesn't mean it's still being used.

NetBIOS for TCP/IP (NBT) was used for decades to perform name resolution, but has since been replaced by LLMNR for name resolution (part of zeroconf on Windows). This legacy system can still be queried with the nbtstat (Windows) or nmblookup (Linux).

The loop attribute should do it:

<video width="320" height="240" autoplay loop>
  <source src="movie.mp4" type="video/mp4" />
  <source src="movie.ogg" type="video/ogg" />
  Your browser does not support the video tag.
</video>

Should you have a problem with the loop attribute (as we had in the past), listen to the videoEnd event and call the play() method when it fires.

Note1: I'm not sure about the behavior on Apple's iPad/iPhone, because they have some restrictions against autoplay.

Note2: loop="true" and autoplay="autoplay" are deprecated

It seems that you have forgotten to add your state server address in the config file.

 <sessionstate mode="StateServer" timeout="20" server="127.0.0.1" port="42424" />

The following will return an ISO8601 and RFC3339-compliant UTC timestamp, including nanoseconds.

It uses strftime(), which works with struct timespec just as well as with struct timeval because all it cares about is the number of seconds, which both provide. Nanoseconds are then appended (careful to pad with zeros!) as well as the UTC suffix 'Z'.

Example output: 2021-01-19T04:50:01.435561072Z

#include <stdio.h>
#include <time.h>
#include <sys/time.h>

int utc_system_timestamp(char[]);

int main(void) {
    char buf[31];
    utc_system_timestamp(buf);
    printf("%s\n", buf);
}

// Allocate exactly 31 bytes for buf
int utc_system_timestamp(char buf[]) {
        const int bufsize = 31;
        struct timespec now;
        struct tm tm;
        int retval = clock_gettime(CLOCK_REALTIME, &now);
        gmtime_r(&now.tv_sec, &tm);
        strftime(buf, bufsize, "%Y-%m-%dT%H:%M:%S.", &tm);
        sprintf(buf, "%s%09luZ", buf, now.tv_nsec);
        return retval;
}

Try this:

$str = "Hello Friend";

$arr1 = str_split($str);
$arr2 = str_split($str, 3);

print_r($arr1);
print_r($arr2);

The above example will output:

Array
(
    [0] => H
    [1] => e
    [2] => l
    [3] => l
    [4] => o
    [5] =>
    [6] => F
    [7] => r
    [8] => i
    [9] => e

    [11] => d

Google basis (free) does not provide address verification (Geocoding) as there is no UK postcode license.

This means postcode searches are very in-accurate. The proximity search is very poor, even for town searches, often not recognising locations.

This is why Google have a premier and a enterprise solution which still is more expensive and not as good as business mapping specialists like bIng and Via Michelin who also have API's.

As a free lance developer, so serious business would use Google as the system is weak and really provides a watered down solution.

These lines Worked for me.

string[] lines = File.ReadAllLines(txtProxyListPath.Text);
var options = new ParallelOptions { MaxDegreeOfParallelism = Environment.ProcessorCount * 10 };
Parallel.ForEach(lines , options, (item) =>
{
 //My Stuff
});

As a Library Project

You should add the resources in a library project as per http://developer.android.com/tools/support-library/setup.html

Section > Adding libraries with resources

You then add the android-support-v7-appcompat library in your workspace and then add it as a reference to your app project.

Defining all the resources in your app project will also work (but there are a lot of definitions to add and you have missed some of them), and it is not the recommended approach.

Color is not data.

The Get.cell technique has flaws.

1. It does not update as soon as the cell color changes, but only when the cell (or the sheet) is recalculated.
2. It does not have sufficient numbers for the millions of colors that are available in modern Excel. See the screenshot and notice how the different intensities of yellow or purple all have the same number.

That does not surprise, since the Get.cell uses an old XML command, i.e. a command from the macro language Excel used before VBA was introduced. At that time, Excel colors were limited to less than 60.

Again: Color is not data.

If you want to color-code your cells, use conditional formatting based on the cell values or based on rules that can be expressed with logical formulas. The logic that leads to conditional formatting can also be used in other places to report on the data, regardless of the color value of the cell.

The return false is saying not to take the default action, which in the case of an <a href> is to follow the link. When you return false to the onclick, then the href will be ignored.

It worked for me:

CGFloat boldTextFontSize = 17.0f;

myLabel.text = [NSString stringWithFormat:@"%@ 2012/10/14 %@",@"Updated:",@"21:59 PM"];

NSRange range1 = [myLabel.text rangeOfString:@"Updated:"];
NSRange range2 = [myLabel.text rangeOfString:@"21:59 PM"];

NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithString:myLabel.text];

[attributedText setAttributes:@{NSFontAttributeName:[UIFont boldSystemFontOfSize:boldTextFontSize]}
                        range:range1];
[attributedText setAttributes:@{NSFontAttributeName:[UIFont boldSystemFontOfSize:boldTextFontSize]}
                        range:range2];

myLabel.attributedText = attributedText;

For Swift version: See Here

Try this:

function welcomeMessage()
{
    var shape1 = new Shape();
    //alert(shape1.draw());
    alert(shape1.hasOwnProperty("name"));
}

When working with reflection in JavaScript, member objects are always refered to as the name as a string. For example:

for(i in obj) { ... }

The loop iterator i will be hold a string value with the name of the property. To use that in code you have to address the property using the array operator like this:

 for(i in obj) {
   alert("The value of obj." + i + " = " + obj[i]);
 }

Your database driver is missing. To solve the probelm

First install the driver

For ubuntu: For mysql database.

sudo apt-get install php5.6-mysql/php7.2-mysql

You also can search for other database systems.

You also can search for the driver:

sudo apt-cache search drivername

Then Run the cmd php artisan migrate

MySQL (and subsequently SQLite) also support the REPLACE INTO syntax:

REPLACE INTO my_table (pk_id, col1) VALUES (5, '123');

This automatically identifies the primary key and finds a matching row to update, inserting a new one if none is found.

To split into more than two classes such as train, test, and validation, one can do:

probs = np.random.rand(len(df))
training_mask = probs < 0.7
test_mask = (probs>=0.7) & (probs < 0.85)
validatoin_mask = probs >= 0.85


df_training = df[training_mask]
df_test = df[test_mask]
df_validation = df[validatoin_mask]

This will put approximately 70% of data in training, 15% in test, and 15% in validation.

Agreed that you've to get authenticated to admin db and needs at least a role with correct privileges which would avoid 'local host exception' from DB(this is for mongoDB's hosted on-premises), though you've everything in place & still getting not authorized exceptions on almost every command, while accessing mongoDB which got created using Mongo Atlas, then here is the place where you might know the reason, why :

https://dba.stackexchange.com/questions/219003/not-authorized-on-admin-to-execute-command-mongodb-atlas-m0-free-tier-cluster?newreg=471a9a26108243d78d4ca74a87e7a115

and also check this if you've hosted mongoDB on mongo Atlas:

https://docs.atlas.mongodb.com/unsupported-commands/

You can also use the jquery prop() method for this.

$(function(){
  $('yourselector').prop('target', '_blank');
});

Assuming you're using WinForms, as it was the first thing I did when I was starting C# you need to create an event to close this form.

Lets say you've got a button called myNewButton. If you double click it on WinForms designer you will create an event. After that you just have to use this.Close

    private void myNewButton_Click(object sender, EventArgs e) {
        this.Close();
    }

And that should be it.

The only reason for this not working is that your Event is detached from button. But it should create new event if old one is no longer attached when you double click on the button in WinForms designer.

$array = range('a', 'z');

You can get selected value also with help of click() by passing the selected value through the function

<md-select placeholder="Select Categorie"  
    name="Select Categorie" >
  <md-option *ngFor="let list of categ" [value]="list.value" (click)="sub_cat(list.category_id)" >
    {{ list.category }}
  </md-option>
</md-select>

Here is a solution worked for me and also, I found all of the above solutions are correct. My excel model got corrupted and which is why my code (similar to this one) stopped working. Here is what worked for me and is working every time-

1. Calculate the workbook- Formulas->Calculate Now (under calculation section)
2. Save the workbook
3. Close and re-open the file. It was fixed and works every time.

I prefer to use WebClient, it seems to handle SSL transparently:

Based nodejs document, http://nodejs.org/api/stream.html#stream_event_finish, it should handle writableStream's finish event.

var writable = getWriteable();

readable.pipe(writable);
writable.on('finish', function(){ ... });

comdlg32.dll is not a COM DLL and cannot be registered.

One way to confirm this for yourself is to run this command:

dumpbin /exports comdlg32.dll

You'll see that comdlg32.dll doesn't contain a DllRegisterServer method. Hence RegSvr32.exe won't work.

That's your answer.

ComDlg32.dll is a a system component. (exists in both c:\windows\system32 and c:\windows\syswow64) Trying to replace it or override any registration with an older version could corrupt the rest of Windows.

I can help more, but I need to know what MSComDlg.CommonDialog is. What does it do and how is it supposed to work? And what version of ComDlg32.dll are you trying to register (and where did you get it)?

Is there a way we can get the list of supported timeZone from MySQL ? ex - serverTimezone=America/New_York. That can solve many such issue. I believe every time you need to specify the correct time zone from the Application irrespective of the DB TimeZone.

Using OnPaint to draw a custom border on your controls is fine. But know how to use OnPaint to keep efficiency up, and render time to a minimum. Read this if you are experiencing a laggy GUI while using custom paint routines: What is the right way to use OnPaint in .Net applications?

Because the accepted answer of PraVn may seem simple, but is actually inefficient. Using a custom control, like the ones posted in the answers above is way better.

Maybe the performance is not an issue in your application, because it is small, but for larger applications with a lot of custom OnPaint routines it is a wrong approach to use the way PraVn showed.

Integer has no method length. Try string

var testvar={};
testvar[1]="2";
alert(testvar[1].length);

By your tags, I'm assuming your using Github. Why not create some branch protection rules for your master branch? That way even if you do try to push to master, it will reject it.

1) Go to the 'Settings' tab of your repo on Github.

2) Click on 'Branches' on the left side-menu.

3) Click 'Add rule'

4) Enter 'master' for a branch pattern.

5) Check off 'Require pull request reviews before merging'

I would also recommend doing the same for your dev branch.

The answer really depends on the complexity you want. For example, I want to outline all my indents with a vertical bar, so my indent string is determined as follows:

return new string(Enumerable.Range(0, indentSize*indent).Select(
  n => n%4 == 0 ? '|' : ' ').ToArray());

There're several open-source libraries which allow console table formatting, ranging from simple (like the code samples in the answers here) to more advanced.

ConsoleTable

Judging by NuGet stats, the most popular library for formatting tables is ConsoleTable. Tables are constructed like this (from the readme file):

var table = new ConsoleTable("one", "two", "three");
table.AddRow(1, 2, 3)
     .AddRow("this line should be longer", "yes it is", "oh");

Tables can be formatted using one of the predefined styles. It'll look like this:

--------------------------------------------------
| one                        | two       | three |
--------------------------------------------------
| 1                          | 2         | 3     |
--------------------------------------------------
| this line should be longer | yes it is | oh    |
--------------------------------------------------

This library expects single-line cells with no formatting.

There're a couple of libraries based on ConsoleTable with slightly extended feature sets, like more line styles.

CsConsoleFormat

If you need more complex formatting, you can use CsConsoleFormat.† Here's a table generated from a process list (from a sample project):

new Grid { Stroke = StrokeHeader, StrokeColor = DarkGray }
    .AddColumns(
        new Column { Width = GridLength.Auto },
        new Column { Width = GridLength.Auto, MaxWidth = 20 },
        new Column { Width = GridLength.Star(1) },
        new Column { Width = GridLength.Auto }
    )
    .AddChildren(
        new Cell { Stroke = StrokeHeader, Color = White }
            .AddChildren("Id"),
        new Cell { Stroke = StrokeHeader, Color = White }
            .AddChildren("Name"),
        new Cell { Stroke = StrokeHeader, Color = White }
            .AddChildren("Main Window Title"),
        new Cell { Stroke = StrokeHeader, Color = White }
            .AddChildren("Private Memory"),
        processes.Select(process => new[] {
            new Cell { Stroke = StrokeRight }
                .AddChildren(process.Id),
            new Cell { Stroke = StrokeRight, Color = Yellow, TextWrap = TextWrapping.NoWrap }
                .AddChildren(process.ProcessName),
            new Cell { Stroke = StrokeRight, Color = White, TextWrap = TextWrapping.NoWrap }
                .AddChildren(process.MainWindowTitle),
            new Cell { Stroke = LineThickness.None, Align = HorizontalAlignment.Right }
                .AddChildren(process.PrivateMemorySize64.ToString("n0")),
        })
    )

The end result will look like this:

It supports any kind of table lines (several included and customizable), multi-line cells with word wrap, colors, columns growing based on content or percentage, text alignment etc.

_{† CsConsoleFormat was developed by me.}

The question is slightly ambiguous, since None can translate into either undefined or null. null is a better choice:

var a = [], b;
var i, j;
for (i = 0; i < 9; i++) {
  for (j = 0, b = []; j < 9; j++) {
    b.push(null);
  }
  a.push(b);
}

If undefined, you can be sloppy and just don't bother, everything is undefined anyway. :)

In Groovy, null == null gets a true. At runtime, you won't know what happened. In Java, == is comparing two references.

This is a cause of big confusion in basic programming, Whether it is safe to use equals. At runtime, a null.equals will give an exception. You've got a chance to know what went wrong.

Especially, you get two values from keys not exist in map(s), == makes them equal.

you can try this
The date is of timestamp type which has the following format: ‘YYYY-MM-DD HH:MM:SS’ or ‘2008-10-05 21:34:02.’

$res = mysql_query("SELECT date FROM times;");
while ( $row = mysql_fetch_array($res) ) {
   echo $row['date'] . "
";
}

The PHP strtotime function parses the MySQL timestamp into a Unix timestamp which can be utilized for further parsing or formatting in the PHP date function.

Here are some other sample date output formats that may be of practical use:

echo date("F j, Y g:i a", strtotime($row["date"]));                  // October 5, 2008 9:34 pm
echo date("m.d.y", strtotime($row["date"]));                         // 10.05.08
echo date("j, n, Y", strtotime($row["date"]));                       // 5, 10, 2008
echo date("Ymd", strtotime($row["date"]));                           // 20081005
echo date('\i\t \i\s \t\h\e jS \d\a\y.', strtotime($row["date"]));   // It is the 5th day.
echo date("D M j G:i:s T Y", strtotime($row["date"]));               // Sun Oct 5 21:34:02 PST 2008

If you use maven, check that you have this plugin in your pom.xml:

    <build>
        <plugins>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>3.2.0</version>
                <executions>
                    <!-- Attach the shade goal into the package phase -->
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>shade</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

        </plugins>
    </build>

It will put your dependency (the exception reason) to your jar.

FYI: this will include all dependencies inflated in the final jar

Further refinig Sglasses method, the above lines force the use of SQLCMD mode, and either treminates the scirpt if not using SQLCMD mode or uses :on error exit to exit on any error
CONTEXT_INFO is used to keep track of the state.

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

You say "I am not using a forms to manipulate the data." But you are doing a POST. Therefore, you are, in fact, using a form, even if it's empty.

$.ajax's dataType tells jQuery what type the server will return, not what you are passing. POST can only pass a form. jQuery will convert data to key/value pairs and pass it as a query string. From the docs:

Data to be sent to the server. It is converted to a query string, if not already a string. It's appended to the url for GET-requests. See processData option to prevent this automatic processing. Object must be Key/Value pairs. If value is an Array, jQuery serializes multiple values with same key i.e. {foo:["bar1", "bar2"]} becomes '&foo=bar1&foo=bar2'.

Therefore:

1. You aren't passing JSON to the server. You're passing JSON to jQuery.
2. Model binding happens in the same way it happens in any other case.

I Have a Query With This result :

SELECT Top 3
 id,
 Paytype
 FROM dbo.OrderExpresses
 WHERE CreateDate > '2018-04-08'

The Result is :

22082   1
22083   2
22084   1

I Want Change The Code To String In Query, So I Use This Code :

SELECT TOP 3

 CASE WHEN Paytype = 1 THEN N'Credit' ELSE N'Cash' END AS PayTypeString
 FROM dbo.OrderExpresses
 WHERE CreateDate > '2018-04-08'

And Result Is :)

22082   Credit
22083   Cash
22084   Credit

A hacky way of doing JSON_UNESCAPED_UNICODE in PHP 5.3. Really disappointed by PHP json support. Maybe this will help someone else.

$array = some_json();
// Encode all string children in the array to html entities.
array_walk_recursive($array, function(&$item, $key) {
    if(is_string($item)) {
        $item = htmlentities($item);
    }
});
$json = json_encode($array);

// Decode the html entities and end up with unicode again.
$json = html_entity_decode($rson);

Since START is the only way to execute something in the background from a CMD script, I would recommend you keep using it. Instead of the /B modifier, try /MIN so the newly created window won't bother you. Also, you can set the priority to something lower with /LOW or /BELOWNORMAL, which should improve your system responsiveness.

--- Shameless plug ---
I have added this function to a library I created vanillajs-browser-helpers: https://github.com/Tokimon/vanillajs-browser-helpers/blob/master/inView.js
-------------------------------

Well BenM stated, you need to detect the height of the viewport + the scroll position to match up with your top position. The function you are using is ok and does the job, though its a bit more complex than it needs to be.

If you don't use jQuery then the script would be something like this:

function posY(elm) {
    var test = elm, top = 0;

    while(!!test && test.tagName.toLowerCase() !== "body") {
        top += test.offsetTop;
        test = test.offsetParent;
    }

    return top;
}

function viewPortHeight() {
    var de = document.documentElement;

    if(!!window.innerWidth)
    { return window.innerHeight; }
    else if( de && !isNaN(de.clientHeight) )
    { return de.clientHeight; }
    
    return 0;
}

function scrollY() {
    if( window.pageYOffset ) { return window.pageYOffset; }
    return Math.max(document.documentElement.scrollTop, document.body.scrollTop);
}

function checkvisible( elm ) {
    var vpH = viewPortHeight(), // Viewport Height
        st = scrollY(), // Scroll Top
        y = posY(elm);
    
    return (y > (vpH + st));
}

Using jQuery is a lot easier:

function checkVisible( elm, evalType ) {
    evalType = evalType || "visible";

    var vpH = $(window).height(), // Viewport Height
        st = $(window).scrollTop(), // Scroll Top
        y = $(elm).offset().top,
        elementHeight = $(elm).height();

    if (evalType === "visible") return ((y < (vpH + st)) && (y > (st - elementHeight)));
    if (evalType === "above") return ((y < (vpH + st)));
}

This even offers a second parameter. With "visible" (or no second parameter) it strictly checks whether an element is on screen. If it is set to "above" it will return true when the element in question is on or above the screen.

See in action: http://jsfiddle.net/RJX5N/2/

I hope this answers your question.

-- IMPROVED VERSION--

This is a lot shorter and should do it as well:

function checkVisible(elm) {
  var rect = elm.getBoundingClientRect();
  var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
  return !(rect.bottom < 0 || rect.top - viewHeight >= 0);
}

with a fiddle to prove it: http://jsfiddle.net/t2L274ty/1/

And a version with threshold and mode included:

function checkVisible(elm, threshold, mode) {
  threshold = threshold || 0;
  mode = mode || 'visible';

  var rect = elm.getBoundingClientRect();
  var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
  var above = rect.bottom - threshold < 0;
  var below = rect.top - viewHeight + threshold >= 0;

  return mode === 'above' ? above : (mode === 'below' ? below : !above && !below);
}

and with a fiddle to prove it: http://jsfiddle.net/t2L274ty/2/

action attribute in <form method="post" action="action="""> should be just action=""

Try This query:

  SUM(CASE datepart(month,ARR_DATE) WHEN 2 THEN 1 ELSE 0 END) AS 'February',
  SUM(CASE datepart(month,ARR_DATE) WHEN 3 THEN 1 ELSE 0 END) AS 'March',
  SUM(CASE datepart(month,ARR_DATE) WHEN 4 THEN 1 ELSE 0 END) AS 'April',
  SUM(CASE datepart(month,ARR_DATE) WHEN 5 THEN 1 ELSE 0 END) AS 'May',
  SUM(CASE datepart(month,ARR_DATE) WHEN 6 THEN 1 ELSE 0 END) AS 'June',
  SUM(CASE datepart(month,ARR_DATE) WHEN 7 THEN 1 ELSE 0 END) AS 'July',

  SUM(CASE datepart(month,ARR_DATE) WHEN 11 THEN 1 ELSE 0 END) AS 'November',
  SUM(CASE datepart(month,ARR_DATE) WHEN 12 THEN 1 ELSE 0 END) AS 'December',
  SUM(CASE datepart(year,ARR_DATE) WHEN 2012 THEN 1 ELSE 0 END) AS 'TOTAL'
FROM
    sometable
WHERE
  ARR_DATE BETWEEN '2012/01/01' AND '2012/12/31' 

Try this

git checkout master

git pull origin master

It will work both, but personally I'd prefer option 2 so the span is "around" the link.

The course contains a logical error:

    assertTrue("Book check in failed", ml.checkIn(b1));

    assertFalse("Book was aleready checked in", ml.checkIn(b1));

In the first assert we expect the checkIn to return True (because checkin is succesful). If this would fail we would print a message like "book check in failed. Now in the second assert we expect the checkIn to fail, because the book was checked in already in the first line. So we expect a checkIn to return a False. If for some reason checkin returns a True (which we don't expect) than the message should never be "Book was already checked in", because the checkin was succesful.

A quick answer:

mvn -fn test

Works with nested project builds.

To get the data form external site by passing using a local proxy as suggested by jherax you can create a php page that fetches the content for you from respective external url and than send a get request to that php page.

var req = new XMLHttpRequest();
req.open('GET', 'http://localhost/get_url_content.php',false);
if(req.status == 200) {
   alert(req.responseText);
}

as a php proxy you can use https://github.com/cowboy/php-simple-proxy

I've heard stories that they were to be included close to the orignal Java release. Oak was the precursor to Java, and in some spec documents there was mention of usigned values. Unfortunately these never made it into the Java language. As far as anyone has been able to figure out they just didn't get implemented, likely due to a time constraint.

My code is super easy and works for any order of matrix

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    System.out.println(" Enter No. of rows in matrix 1 : ");
    int arows = sc.nextInt();
    System.out.println(" Enter No. of columns in matrix 1 : ");
    int acols = sc.nextInt();
    System.out.println(" Enter No. of rows in matrix 2 : ");
    int brows = sc.nextInt();
    System.out.println(" Enter No. of columns in matrix 2 : ");
    int bcols = sc.nextInt();
    if (acols == brows) {
        System.out.println(" Enter elements of matrix 1 ");
        int a[][] = new int[arows][acols];
        int b[][] = new int[brows][bcols];
        for (int i = 0; i < arows; i++) {
            for (int j = 0; j < acols; j++) {
                a[i][j] = sc.nextInt();
            }
        }
        System.out.println(" Enter elements of matrix 2 ");
        for (int i = 0; i < brows; i++) {
            for (int j = 0; j < bcols; j++) {
                b[i][j] = sc.nextInt();
            }
        }
        System.out.println(" The Multiplied matrix is : ");
        int sum = 0;
        int c[][] = new int[arows][bcols];
        for (int i = 0; i < arows; i++) {
            for (int j = 0; j < bcols; j++) {
                for (int k = 0; k < brows; k++) {
                    sum = sum + a[i][k] * b[k][j];
                    c[i][j] = sum;
                }

                System.out.print(c[i][j] + " ");
                sum = 0;
            }
            System.out.println();
        }
    } else {
        System.out.println("Order of matrix in invalid");
    }
}

Using either 0 or NULL will have the same effect.

However, that doesn't mean that they are both good programming practices. Given that there is no difference in performance, choosing a low-level-aware option over an agnostic/abstract alternative is a bad programming practice. Help readers of your code understand your thought process.

NULL, 0, 0.0, '\0', 0x00 and whatelse all translate to the same thing, but are different logical entities in your program. They should be used as such. NULL is a pointer, 0 is quantity, 0x0 is a value whose bits are interesting etc. You wouldn't assign '\0' to a pointer whether it compiles or not.

I know some communities encourage demonstrating in-depth knowledge of an environment by breaking the environment's contracts. Responsible programmers, however, make maintainable code and keep such practices out of their code.

There is a way to do it using reflection. It works with .NET 4.0. It accesses a private field and may not work in other versions of .NET without modifications.

I have no idea why Microsoft did not expose this field with a property.

private static int GetStatusCode(WebClient client, out string statusDescription)
{
    FieldInfo responseField = client.GetType().GetField("m_WebResponse", BindingFlags.Instance | BindingFlags.NonPublic);

    if (responseField != null)
    {
        HttpWebResponse response = responseField.GetValue(client) as HttpWebResponse;

        if (response != null)
        {
            statusDescription = response.StatusDescription;
            return (int)response.StatusCode;
        }
    }

    statusDescription = null;
    return 0;
}

Remove the extension altogether and then double-click it. Most system shell scripts are like this. As long as it has a shebang it will work.

new File(absolutePath).getName();

Let's not forget our relatively new friend, java-8 stream API. If you need to preprocess list before converting it to a set, it's better to have something like:

list.stream().<here goes some preprocessing>.collect(Collectors.toSet());

Some frameworks are using this header to detect xhr requests e.g. grails spring security is using this header to identify xhr request and give either a json response or html response as response.

Most Ajax libraries (Prototype, JQuery, and Dojo as of v2.1) include an X-Requested-With header that indicates that the request was made by XMLHttpRequest instead of being triggered by clicking a regular hyperlink or form submit button.

You don't specify the tables for Company and Date, and you might want to fix that.

Standard SQL using MERGE:

MERGE WorkRecord2 T
   USING Employee S
      ON T.EmployeeRun = S.EmployeeNo
         AND Company = '1'
         AND Date = '2013-05-06'
WHEN MATCHED THEN DELETE;

The answer from Devart is also standard SQL, though incomplete. It should look more like this:

DELETE
  FROM WorkRecord2
  WHERE EXISTS ( SELECT *
                   FROM Employee S
                  WHERE S.EmployeeNo = WorkRecord2.EmployeeRun
                        AND Company = '1'
                        AND Date = '2013-05-06' );

The important thing to note about the above is it is clear the delete is targeting a single table, as enforced in the second example by requiring a scalar subquery.

For me, the various proprietary syntax answers are harder to read and understand. I guess the mindset for is best described in the answer by frans eilering, i.e. the person writing the code doesn't necessarily care about the person who will read and maintain the code.

This error means you can not directly load data from file system because there are security issues behind this. The only solution that I know is create a web service to serve load files.

In addition to the App Engine vs Compute Engine notes above the list here also includes a comparison with Google Kubernete Engine and some notes based on experience with a wide range of apps from small to very large. For more points see the Google Cloud Platform documentation high level description of features in App Engine Standard and Flex on the page Choosing an App Engine Environment. For another comparison of deployment of App Engine and Kubernetes see the post by Daz Wilkin App Engine Flex or Kubernetes Engine.

App Engine Standard

Pros

• Very economical for low traffic apps in terms of direct costs and also the cost of maintaining the app.
• Auto scaling is fast. Autoscaling in App Engine is based on lightweight instance classes F1-F4.
• Version management and traffic splitting are fast and convenient. These features are built into App Engine (both Standard and Flex) natively.
• Minimal management, developers need focus only on their app. Developers do not need to worry about managing VMs in a reliable, as in GCE, or learning about clusters, as with GKE.
• Access to Datastore is fast. When App Engine was first released, the runtime was co-located with Datastore. Later Datastore was split out as the standalone product Cloud Datastore but the co-location of App Engine Standard serving with Datastore remains.
• Access to Memcache is supported.
• The App Engine sandbox is very secure. Compared with development on GCE or other virtual machines, where you need to do your own diligence to prevent the virtual machine from being taken over at the operating system level, the App Engine Standard sandbox is relatively secure by default.

Cons

• Generally more constrained than other environments Instances are smaller. Although this is good for rapid autoscaling, many apps can benefit from larger instances, such as GCE instance sizes up to 96 cores.
• Networking is not integrated with GCE
• Cannot put App Engine behind a Google Cloud Load Balancer. Limited to supported runtimes: Python 2.7, Java 7 and 8, Go 1.6-1.9, and PHP 5.5. In Java, there is some support for Servlets but not the full J2EE standard.

App Engine Flex

Pros

• Can use a custom runtime
• Native integration with GCE networking
• Version and traffic management is convenient, same as Standard
• The larger instance sizes may be more suitable to to large complex applications, especially Java applications that can use a lot of memory

Cons

• Network integration is not perfect - no integration with internal load balancers or Shared Virtual Private Clouds
• Access to managed Memcache not generally available

Google Kubernetes Engine

Pros

• Native integration with containers allows custom runtimes and greater control over cluster configuration.
• Embodies many best practices working with virtual machines, such as immutable runtime environments and easy ability to roll back to previous versions
• Provides a consistent and repeatable deployment framework
• Based on open standards, notably Kubernetes, for portability between clouds and on-premises.
• Version management can accomplished with Docker containers and the Google Container Registry

Cons

• Traffic splitting and management is do-it-yourself, possibly leveraging Istio and Envoy
• Some management overhead
• Some time to ramp up on Kubernetes concepts, such as pods, deployments, services, ingress, and namespaces
• Need to expose some public IPs unless using Private Clusters, now in beta, eliminate that need but you still need to provide access to locations where kubectl commands will be run from.
• Monitoring integration not perfect
• While L3 internal load balancing is supported natively on Kubernetes Engine, L7 internal load balancing is do-it-yourself, possibly leveraging Envoy

Compute Engine

Pros

• Easy to ramp up - no need to ramp up on Kubernetes or App Engine, just reuse whatever you know from previous experience. This is probably the main reason for using Compute Engine directly.
• Complete control - you can leverage many Compute Engine features directly and install the latest of all your favorite stuff to stay on the bleeding edge.
• No need for public IPs. Some legacy software may be too hard to lock down if anything is exposed on public IPs.
• You can leverage the Container-Optimized OS for running Docker containers

Cons

• Mostly do-it-yourself, which can be challenging to do adequately for reliability and security, although you can reuse solutions from various places, including the Cloud Launcher.
• More management overhead. There are many management tools for Compute Engine but they will not necessarily understand how you have deployed your application, like the App Engine and Kubernetes Engine monitoring tools do
• Autoscaling is based on GCE instances, which can be slower than App Engine
• Tendency is to install software on snowflake GCE instances, which can be some effort to maintain

fileConn<-file("output.txt")
writeLines(c("Hello","World"), fileConn)
close(fileConn)

You need to escape backslash with a \

  $str = str_replace ("\\", "/", $str);

This can be accomplished in two steps:

1: select the element you want to change by either tagname, id, class etc.

var element = document.getElementsByTagName('h2')[0];

2. remove the style attribute

element.removeAttribute('style');

One way is just to revert your settings: If you delete the Metadata folder in your workspace eclipse will revert to its factory state for all settings (both perspective and general).

The other answers are great but I thought I'd take a different tact.

If all you are really looking for is to slow down a specific file in linux:

 rm slowfile; mkfifo slowfile; perl -e 'select STDOUT; $| = 1; while(<>) {print $_; sleep(1) if (($ii++ % 5) == 0); }' myfile > slowfile  &

node myprog slowfile

This will sleep 1 sec every five lines. The node program will go as slow as the writer. If it is doing other things they will continue at normal speed.

The mkfifo creates a first-in-first-out pipe. It's what makes this work. The perl line will write as fast as you want. The $|=1 says don't buffer the output.

You don't need to change the delimiter to display the right part of the string with cut.

The -f switch of the cut command is the n-TH element separated by your delimiter : :, so you can just type :

 grep puddle2_1557936 | cut -d ":" -f2

Another solutions (adapt it a bit) if you want fun :

Using grep :

grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                        
/home/rogers.williams/folderz/puddle2

or still with look around regex

grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                    
/home/rogers.williams/folderz/puddle2

or with perl :

perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                      
/home/rogers.williams/folderz/puddle2

or using ruby (thanks to glenn jackman)

ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with awk :

awk -F'puddle2_1557936:' '{print $2}'  <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with python :

python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or using only bash :

IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2

or using js in a shell :

js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2

or using php in a shell :

php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2' 
/home/rogers.williams/folderz/puddle2

Just in case anyone still stumbles upon this old question:

The code was theoretically almost correct in a sense, the problem was the use of $('this') instead of $(this), therefore telling jQuery to look for a tag.

$(document).ready(function(){
  $("#frame").click(function () { 
    $(this).load("http://www.google.com/");
  });
});

The script itself woudln't work as it is right now though because the load() function itself is an AJAX function, and google does not seem to specifically allow the use of loading this page with AJAX, but this method should be easy to use in order to load pages from your own domain by using relative paths.

1. replace all seperator: (\W) with seperator + new_seperator: (\W;)

2. split by the new_seperator: (;)

def split_and_keep(seperator, s):
  return re.split(';', re.sub(seperator, lambda match: match.group() + ';', s))

print('\W', 'foo/bar spam\neggs')
