The copy command is a SQL*Plus command (not a SQL Developer command). If you have your tnsname entries setup for SID1 and SID2 (e.g. try a tnsping), you should be able to execute your command.

Another assumption is that table1 has the same columns as the message_table (and the columns have only the following data types: CHAR, DATE, LONG, NUMBER or VARCHAR2). Also, with an insert command, you would need to be concerned about primary keys (e.g. that you are not inserting duplicate records).

I tried a variation of your command as follows in SQL*Plus (with no errors):

copy from scott/tiger@db1 to scott/tiger@db2 create new_emp using select * from emp;

After I executed the above statement, I also truncate the new_emp table and executed this command:

copy from scott/tiger@db1 to scott/tiger@db2 insert new_emp using select * from emp;

With SQL Developer, you could do the following to perform a similar approach to copying objects:

1. On the tool bar, select Tools>Database copy.

2. Identify source and destination connections with the copy options you would like.

3. For object type, select table(s).

4. Specify the specific table(s) (e.g. table1).

The copy command approach is old and its features are not being updated with the release of new data types. There are a number of more current approaches to this like Oracle's data pump (even for tables).

In Addition to @Dev Blanked answer, if you want to use an existing bean that was created by Spring the code can be modified to:

@RunWith(MockitoJUnitRunner.class)
public class DemoTest {

    @Inject
    private ApplicationContext ctx;

    @Spy
    private SomeService service;

    @InjectMocks
    private Demo demo;

    @Before
    public void setUp(){
        service = ctx.getBean(SomeService.class);
    }

    /* ... */
}

This way you don't need to change your code (add another constructor) just to make the tests work.

As @StahlRat already answered. I would like to add another method for it. There is extension pack for Python Default idle editor Python Extensions Package.

For bootstap 4.5: I just copied this code from bootstap 5.scss to my sass and its amazing:

@media (max-width: 1399.98px) 
  .modal-fullscreen-xxl-down 
    width: 100vw
    max-width: none
    height: 100%
    margin: 0
  
  .modal-fullscreen-xxl-down .modal-content 
    height: 100%
    border: 0
    border-radius: 0
  
  .modal-fullscreen-xxl-down .modal-header 
    border-radius: 0
  
  .modal-fullscreen-xxl-down .modal-body 
    overflow-y: auto
  
  .modal-fullscreen-xxl-down .modal-footer 
    border-radius: 0

For html:

<!-- Full screen modal -->
<div class="modal-dialog modal-fullscreen-xxl-down">
  ...
</div>

Its all about controling margin, width and height of the right div.

I had the exact issue, tried several soultion didnt work , lastly restarted the system , it worked fine.

Slight bias to SQL Server

• Best approach to remove time part of datetime in SQL Server
• Most efficient way in SQL Server to get date from date+time?

Summary

DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0)

SQL Server 2008 has date type though. So just use

CAST(GETDATE() AS DATE)

Edit: To add one day, compare to the day before "zero"

DATEADD(day, DATEDIFF(day, -1, GETDATE()), 0)

From cyberkiwi:

An alternative that does not involve 2 functions is (the +1 can be in or ourside the brackets).

DATEDIFF(DAY, 0, GETDATE() +1)

DateDiff returns a number but for all purposes this will work as a date wherever you intend to use this expression, except converting it to VARCHAR directly - in which case you would have used the CONVERT approach directly on GETDATE(), e.g.

convert(varchar, GETDATE() +1, 102)

I just used the javascript console in Chrome to do this. I replaced some of your stuff with placeholders.

var temp= ['one', 'two', 'three']; //'${temp}';
//alert(options);
var $select = $('<select>'); //$('#down');                        
$select.find('option').remove();                          
$.each(temp, function(key, value) {              
    $('<option>').val(key).text(value).appendTo($select);
});
console.log($select.html());

Output:

<option value="0">one</option><option value="1">two</option><option value="2">three</option>

However it looks like your json is probably actually a string because the following will end up doing what you describe. So make your JSON actual JSON not a string.

var temp= "['one', 'two', 'three']"; //'${temp}';
//alert(options);
var $select = $('<select>'); //$('#down');                        
$select.find('option').remove();                          
$.each(temp, function(key, value) {              
    $('<option>').val(key).text(value).appendTo($select);
});
console.log($select.html());

reload(module), but only if it's completely stand-alone. If anything else has a reference to the module (or any object belonging to the module), then you'll get subtle and curious errors caused by the old code hanging around longer than you expected, and things like isinstance not working across different versions of the same code.

If you have one-way dependencies, you must also reload all modules that depend on the reloaded module to get rid of all the references to the old code. And then reload modules that depend on the reloaded modules, recursively.

If you have circular dependencies, which is very common for example when you are dealing with reloading a package, you must unload all the modules in the group in one go. You can't do this with reload() because it will re-import each module before its dependencies have been refreshed, allowing old references to creep into new modules.

The only way to do it in this case is to hack sys.modules, which is kind of unsupported. You'd have to go through and delete each sys.modules entry you wanted to be reloaded on next import, and also delete entries whose values are None to deal with an implementation issue to do with caching failed relative imports. It's not terribly nice but as long as you have a fully self-contained set of dependencies that doesn't leave references outside its codebase, it's workable.

It's probably best to restart the server. :-)

'O' stands for object.

#Loading a csv file as a dataframe
import pandas as pd 
train_df = pd.read_csv('train.csv')
col_name = 'Name of Employee'

#Checking the datatype of column name
train_df[col_name].dtype

#Instead try printing the same thing
print train_df[col_name].dtype

The first line returns: dtype('O')

The line with the print statement returns the following: object

Search across files - Press Ctrl+Shift+F

Find - Press Ctrl+F

Find and Replace - Ctrl+H

Note : For mac the Ctrl represents the command button

If I want something like sed, then I usually just call sed itself using the sh library.

from sh import sed

sed(['-i', 's/^# deb/deb/', '/etc/apt/sources.list'])

Sure, there are downsides. Like maybe the locally installed version of sed isn't the same as the one you tested with. In my cases, this kind of thing can be easily handled at another layer (like by examining the target environment beforehand, or deploying in a docker image with a known version of sed).

function return_var_dump(){
    // It works like var_dump, but it returns a string instead of printing it.
    $args = func_get_args(); // For <5.3.0 support ...
    ob_start();
    call_user_func_array('var_dump', $args);
    return ob_get_clean();
}

Inspired from code found above (credits), the simple blocking (aka not CPU consuming) macOS version I was looking for:

import termios
import sys
import fcntl
import os

def getKeyCode(blocking = True):
    fd = sys.stdin.fileno()
    oldterm = termios.tcgetattr(fd)
    newattr = termios.tcgetattr(fd)
    newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
    termios.tcsetattr(fd, termios.TCSANOW, newattr)
    if not blocking:
        oldflags = fcntl.fcntl(fd, fcntl.F_GETFL)
        fcntl.fcntl(fd, fcntl.F_SETFL, oldflags | os.O_NONBLOCK)
    try:
        return ord(sys.stdin.read(1))
    except IOError:
        return 0
    finally:
        termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)
        if not blocking:
            fcntl.fcntl(fd, fcntl.F_SETFL, oldflags)

def getKeyStroke():

    else:
        return chr(code)

There is no inherent ordering to a table. So, the row number itself is a meaningless metric.

However, you can get the row number of a result set by using the ROWNUM psuedocolumn or the ROW_NUMBER() analytic function, which is more powerful.

As there is no ordering to a table both require an explicit ORDER BY clause in order to work.

select rownum, a.*
  from ( select *
           from student
          where name like '%ram%'
          order by branch
                ) a

or using the analytic query

select row_number() over ( order by branch ) as rnum, a.*
  from student
 where name like '%ram%'

Your syntax where name is like ... is incorrect, there's no need for the IS, so I've removed it.

The ORDER BY here relies on a binary sort, so if a branch starts with anything other than B the results may be different, for instance b is greater than B.

To get rid of the first column of NAs, you can do it with negative indexing (which removes indices from the R data set). For example:

output = matrix(1:6, 2, 3) # gives you a 2 x 3 matrix filled with the numbers 1 to 6

# output = 
#           [,1] [,2] [,3]
#     [1,]    1    3    5
#     [2,]    2    4    6

output = output[,-1] # this removes column 1 for all rows

# output = 
#           [,1] [,2]
#     [1,]    3    5
#     [2,]    4    6

So you can just add output = output[,-1]after the for loop in your original code.

Just use the JSON.stringify method and pass it through as the "data" parameter for the $.ajax function, like follows:

$.ajax({
    type: "POST",
    url: "index.php",
    dataType: "json",
    data: JSON.stringify({ paramName: info }),
    success: function(msg){
        $('.answer').html(msg);
    }
});

You just need to make sure you include the JSON2.js file in your page...

Floats are used to store a wider range of number than can be fit in an integer. These include decimal numbers and scientific notation style numbers that can be bigger values than can fit in 32 bits. Here's the deep dive into them: http://en.wikipedia.org/wiki/Floating_point

Use Form.Activate() or Form.Focus() methods.

This is all assuming that the datatype of the column has an implicit conversion for any existing data. I've run into several situations where the existing data, let's say a String can be implicitly converted into the new datatype, let's say Date.

In this situation, it's helpful to know you can create migrations with data conversions. Personally, I like putting these in my model file, and then removing them after all database schemas have been migrated and are stable.

/app/models/table.rb
  ...
  def string_to_date
    update(new_date_field: date_field.to_date)
  end

  def date_to_string
    update(old_date_field: date_field.to_s)
  end
  ...

    def up
        # Add column to store converted data
        add_column :table_name, :new_date_field, :date
        # Update the all resources
        Table.all.each(&:string_to_date)
        # Remove old column
        remove_column :table_name, :date_field
        # Rename new column
        rename_column :table_name, :new_date_field, :date_field
    end

    # Reversed steps does allow for migration rollback
    def down
        add_column :table_name, :old_date_field, :string
        Table.all.each(&:date_to_string)
        remove_column :table_name, :date_field
        rename_column :table_name, :old_date_field, :date_field
    end

It is hard to make a good timing, because the performance.dominteractive is miscalulated (anyway an interesting link for timing developers).

When dom is parsed it still may load and execute deferred scripts. And inline scripts waiting for css (css blocking dom) has to be loaded also until DOMContentloaded. So it is not yet parsed?

And we have readystatechange event where we can look at readyState that unfortunately is missing "dom is parsed" that happens somewhere between "loaded" and "interactive".

Everything becomes problematic when even not the Timing API gives us a time when dom stoped parsing HTML and starting The End process. This standard say the first point has to be that "interactive" fires precisely after dom parsed! Both Chrome and FF has implemented it when document has finished loading sometime after it has parsed. They seem to (mis)interpret the standars as parsing continues beyond deferred scripts executed while people misinterpret DOMContentLoaded as something hapen before defered executing and not after. Anyway...

My recommendation for you is to read about? Navigation Timing API. Or go the easy way and choose a oneliner of these, or run all three and look in your browsers console ...

  document.addEventListener('readystatechange', function() { console.log("Fiered '" + document.readyState + "' after " + performance.now() + " ms"); });

  document.addEventListener('DOMContentLoaded', function() { console.log("Fiered DOMContentLoaded after " + performance.now() + " ms"); }, false);

  window.addEventListener('load', function() { console.log("Fiered load after " + performance.now() + " ms"); }, false);

The time is in milliseconds after document started. I have verified with Navigation? Timing API.

To get seconds for exampe from the time you did var ti = performance.now() you can do parseInt(performance.now() - ti) / 1000

Instead of that kind of performance.now() subtractions the code get little shorter by User Timing API where you set marks in your code and measure between marks.

to send over gmail, you need to use an encrypted connection. this is not possible with telnet alone, but you can use tools like openssl

either connect using the starttls option in openssl to convert the plain connection to encrypted...

openssl s_client -starttls smtp -connect smtp.gmail.com:587 -crlf -ign_eof

or connect to a ssl sockect directly...

openssl s_client -connect smtp.gmail.com:465 -crlf -ign_eof

EHLO localhost

after that, authenticate to the server using the base64 encoded username/password

AUTH PLAIN AG15ZW1haWxAZ21haWwuY29tAG15cGFzc3dvcmQ=

to get this from the commandline:

echo -ne '\[email protected]\00password' | base64
AHVzZXJAZ21haWwuY29tAHBhc3N3b3Jk

then continue with "mail from:" like in your example

Try to look at the following link: Python | change text color in shell

Or read here: http://bytes.com/topic/python/answers/21877-coloring-print-lines

In general solution is to use ANSI codes while printing your string.

There is a solution that performs exactly what you need.

Currently (July 2015), HTML escape sequences (• •) do not work in browser version of Play Store, they're displayed as text. Though, Play Store app handles them as expected.

So, if you're after the unicode bullet point in your app/update description [that's what's got you here, most likely], just copy-paste the bullet character

•

PS You can also use unicode input combo to get the character

Linux: CtrlShiftu 2022 Enter or Space

Mac: Hold ? 2022 release ?

Windows: Hold Alt 2022 release Alt

Mac and Windows require some setup, read on Wikipedia

PPS If you're feeling creative, here's a good link with more copypastable symbols, but don't go too crazy, nobody likes clutter in what they read.

With Swift 5.1, Grand Central Dispatch offers many ways to solve your problem. According to your needs, you may choose one of the seven patterns shown in the following Playground snippets.

#1. Using DispatchGroup, DispatchGroup's notify(qos:flags:queue:execute:) and DispatchQueue's async(group:qos:flags:execute:)

The Apple Developer Concurrency Programming Guide states about DispatchGroup:

Dispatch groups are a way to block a thread until one or more tasks finish executing. You can use this behavior in places where you cannot make progress until all of the specified tasks are complete. For example, after dispatching several tasks to compute some data, you might use a group to wait on those tasks and then process the results when they are done.

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let queue = DispatchQueue(label: "com.company.app.queue", attributes: .concurrent)
let group = DispatchGroup()

queue.async(group: group) {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
}

queue.async(group: group) {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
}

group.notify(queue: queue) {
    print("#3 finished")
}

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 */

#2. Using DispatchGroup, DispatchGroup's wait(), DispatchGroup's enter() and DispatchGroup's leave()

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let queue = DispatchQueue(label: "com.company.app.queue", attributes: .concurrent)
let group = DispatchGroup()

group.enter()
queue.async {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
    group.leave()
}

group.enter()
queue.async {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
    group.leave()
}

queue.async {
    group.wait()
    print("#3 finished")
}

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 */

Note that you can also mix DispatchGroup wait() with DispatchQueue async(group:qos:flags:execute:) or mix DispatchGroup enter() and DispatchGroup leave() with DispatchGroup notify(qos:flags:queue:execute:).

#3. Using Dispatch?Work?Item?Flags barrier and DispatchQueue's async(group:qos:flags:execute:)

Grand Central Dispatch Tutorial for Swift 4: Part 1/2 article from Raywenderlich.com gives a definition for barriers:

Dispatch barriers are a group of functions acting as a serial-style bottleneck when working with concurrent queues. When you submit a DispatchWorkItem to a dispatch queue you can set flags to indicate that it should be the only item executed on the specified queue for that particular time. This means that all items submitted to the queue prior to the dispatch barrier must complete before the DispatchWorkItem will execute.

Usage:

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let queue = DispatchQueue(label: "com.company.app.queue", attributes: .concurrent)

queue.async {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
}

queue.async {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
}

queue.async(flags: .barrier) {
    print("#3 finished")
}

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 */

#4. Using DispatchWorkItem, Dispatch?Work?Item?Flags's barrier and DispatchQueue's async(execute:)

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let queue = DispatchQueue(label: "com.company.app.queue", attributes: .concurrent)

queue.async {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
}

queue.async {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
}

let dispatchWorkItem = DispatchWorkItem(qos: .default, flags: .barrier) {
    print("#3 finished")
}

queue.async(execute: dispatchWorkItem)

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 */

#5. Using DispatchSemaphore, DispatchSemaphore's wait() and DispatchSemaphore's signal()

Soroush Khanlou wrote the following lines in The GCD Handbook blog post:

Using a semaphore, we can block a thread for an arbitrary amount of time, until a signal from another thread is sent. Semaphores, like the rest of GCD, are thread-safe, and they can be triggered from anywhere. Semaphores can be used when there’s an asynchronous API that you need to make synchronous, but you can’t modify it.

Apple Developer API Reference also gives the following discussion for DispatchSemaphore init(value:?) initializer:

Passing zero for the value is useful for when two threads need to reconcile the completion of a particular event. Passing a value greater than zero is useful for managing a finite pool of resources, where the pool size is equal to the value.

Usage:

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let queue = DispatchQueue(label: "com.company.app.queue", attributes: .concurrent)
let semaphore = DispatchSemaphore(value: 0)

queue.async {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
    semaphore.signal()
}

queue.async {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
    semaphore.signal()
}

queue.async {
    semaphore.wait()
    semaphore.wait()    
    print("#3 finished")
}

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 */

#6. Using OperationQueue and Operation's addDependency(_:)

The Apple Developer API Reference states about Operation?Queue:

Operation queues use the libdispatch library (also known as Grand Central Dispatch) to initiate the execution of their operations.

Usage:

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let operationQueue = OperationQueue()

let blockOne = BlockOperation {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
}

let blockTwo = BlockOperation {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
}

let blockThree = BlockOperation {
    print("#3 finished")
}

blockThree.addDependency(blockOne)
blockThree.addDependency(blockTwo)

operationQueue.addOperations([blockThree, blockTwo, blockOne], waitUntilFinished: false)

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 or
 #2 started
 #1 started
 #2 finished
 #1 finished
 #3 finished
 */

#7. Using OperationQueue and OperationQueue's addBarrierBlock(_:) (requires iOS 13)

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let operationQueue = OperationQueue()

let blockOne = BlockOperation {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
}

let blockTwo = BlockOperation {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
}

operationQueue.addOperations([blockTwo, blockOne], waitUntilFinished: false)
operationQueue.addBarrierBlock {
    print("#3 finished")
}

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 or
 #2 started
 #1 started
 #2 finished
 #1 finished
 #3 finished
 */

You can try export http_proxy=http://your_proxy:your_port

If you want user readable data but still detailed, you can use platform.platform()

>>> import platform
>>> platform.platform()
'Linux-3.3.0-8.fc16.x86_64-x86_64-with-fedora-16-Verne'

platform also has some other useful methods:

>>> platform.system()
'Windows'
>>> platform.release()
'XP'
>>> platform.version()
'5.1.2600'

Here's a few different possible calls you can make to identify where you are

import platform
import sys

The outputs of this script ran on a few different systems (Linux, Windows, Solaris, MacOS) and architectures (x86, x64, Itanium, power pc, sparc) is available here: https://github.com/hpcugent/easybuild/wiki/OS_flavor_name_version

e.g. Solaris on sparc gave:

dist: ('', '', '')
linux_distribution: ('', '', '')

For me it was simply a matter of restarting the docker daemon..

There is a property in <Button> that is android:textAllCaps="false" that make characters in which you want in your own Small and caps. By Default its became True so write this code and make textAllCaps=false then you can write text on button in small and Caps letter as per your requirement. Complete code for a Button which allow use to write letters as per our requirement.

 <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/btnLogin"
            android:text="Login for Chat"
            android:textAllCaps="false"/>

you can use this one.

<div id="test"></div>

you java script code should be like that.

setInterval(function(){
      $('#test').load('test.php');
 },5000);

It's also possible to do something like this with ng-style:

ng-style="image_path != '' && {'background-image':'url('+image_path+')'}"

which would not attempt to fetch a non-existing image.

I usually prefer to work with deltas in translate animation, since it avoids a lot of confusion.

Try this out, see if it works for you:

TranslateAnimation anim = new TranslateAnimation(0, amountToMoveRight, 0, amountToMoveDown);
anim.setDuration(1000);

anim.setAnimationListener(new TranslateAnimation.AnimationListener() {

    @Override
    public void onAnimationStart(Animation animation) { }

    @Override
    public void onAnimationRepeat(Animation animation) { }

    @Override
    public void onAnimationEnd(Animation animation) 
    {
        FrameLayout.LayoutParams params = (FrameLayout.LayoutParams)view.getLayoutParams();
        params.topMargin += amountToMoveDown;
        params.leftMargin += amountToMoveRight;
        view.setLayoutParams(params);
    }
});

view.startAnimation(anim);

Make sure to make amountToMoveRight / amountToMoveDown final

Hope this helps :)

U can also use PoDoFo library. The main goal is that it published under LGPL. Since it is written in C++ you should cross-compile it using NDK and write C-side and Java wrapper. Some of third-party libraries can be used from OpenCV project. Also in OpenCV project U can find android.toolchain.cmake file, which will help you with generating Makefile.

You can use this code snippet ...

<html>
  <body>
     <form>
          <input type="radio" name="color" value="black" required />
          <input type="radio" name="color" value="white" />
          <input type="submit" value="Submit" />
    </form>
  </body>
</html>

Specify "required" keyword in one of the select statements. If you want to change the default way of its appearance. You can follow these steps. This is just for extra info if you have any intention to modify the default behavior.

Add the following into you .css file.

/* style all elements with a required attribute */
:required {
  background: red;
}

For more information you can refer following URL.

https://css-tricks.com/almanac/selectors/r/required/

You should override Equals and GetHashCode meaningfully, in this case to compare the ID:

public class LinqTest
{
    public int id { get; set; }
    public string value { get; set; }

    public override bool Equals(object obj)
    {
        LinqTest obj2 = obj as LinqTest;
        if (obj2 == null) return false;
        return id == obj2.id;
    }

    public override int GetHashCode()
    {
        return id;
    }
}

Now you can use Distinct:

List<LinqTest> uniqueIDs = myList.Distinct().ToList();

Leaving my specific solution of this for prosperity, as it's a tricky version of this problem:

Type 'System.Linq.Enumerable+WhereSelectArrayIterator[T...] was not marked as serializable

Due to a class with an attribute IEnumerable<int> eg:

[Serializable]
class MySessionData{
    public int ID;
    public IEnumerable<int> RelatedIDs; //This can be an issue
}

Originally the problem instance of MySessionData was set from a non-serializable list:

MySessionData instance = new MySessionData(){ 
    ID = 123,
    RelatedIDs = nonSerizableList.Select<int>(item => item.ID)
};

The cause here is the concrete class that the Select<int>(...) returns, has type data that's not serializable, and you need to copy the id's to a fresh List<int> to resolve it.

RelatedIDs = nonSerizableList.Select<int>(item => item.ID).ToList();

Worked for me:

1. Download package (see links below), name it lp.cab and place it to your C: drive

2. Run the following commands as Administrator:

2.1 installing new language

dism /Online /Add-Package /PackagePath:C:\lp.cab

2.2 get installed packages

dism /Online /Get-Packages

2.3 remove original package

dism /Online /Remove-Package /PackageName:Microsoft-Windows-Client-LanguagePack-Package~31bf3856ad364e35~amd64~ru-RU~10.0.10240.16384

If you don't know which is your original package you can check your installed packages with this line

dism /Online /Get-Packages | findstr /c:"LanguagePack"

3. Enjoy your new system language

I am not sure about gson but this is how you do it with Jon.sample hope there must be similar way using gson

{ "Players": [ "player 1", "player 2", "player 3", "player 4", "player 5" ] }

===============================================

import java.io.FileReader;
import java.util.List;

import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JosnFileDemo {

    public static void main(String[] args) throws Exception
    {
        String jsonfile ="fileloaction/fileName.json";


                FileReader reader = null;
                JSONObject jsb = null;
                try {
                    reader = new FileReader(jsonfile);
                    JSONParser jsonParser = new JSONParser();
                     jsb = (JSONObject) jsonParser.parse(reader);
                } catch (Exception e) {
                    throw new Exception(e);
                } finally {
                    if (reader != null)
                        reader.close();
                }
                List<String> Players=(List<String>) jsb.get("Players");
                for (String player : Players) {
                    System.out.println(player);
                }           
    }
}

Actually, the following is the cleanest implementation I have seen so far. It uses an annotation to convert a comment into a string variable...

/**
  <html>
    <head/>
    <body>
      <p>
        Hello<br/>
        Multiline<br/>
        World<br/>
      </p>
    </body>
  </html>
  */
  @Multiline
  private static String html;

So, the end result is that the variable html contains the multiline string. No quotes, no pluses, no commas, just pure string.

This solution is available at the following URL... http://www.adrianwalker.org/2011/12/java-multiline-string.html

Hope that helps!

You're right in thinking that, in order to share an image in this way without going down the Twitter Cards route, you need to to have tweeted the image already. As you say, it's also important that you grab the image link that's of the form pic.twitter.com/NuDSx1ZKwy

This step-by-step guide is worth checking out for anyone looking to implement a 'tweet this' link or button: http://onlinejournalismblog.com/2015/02/11/how-to-make-a-tweetable-image-in-your-blog-post/.

Try Clink. It's awesome, especially if you are used to bash keybindings and features.

(As already pointed out - there is a similar question: Is there a better Windows Console Window?)

First Collection is class Interface and you can not instantiate. Collection API

List Ver APi is also an interface class.

It may be so

List list = Collections.synchronizedList(new ArrayList(...)); 

ver enter link description here

Collection collection= Collections.synchronizedList(new ArrayList(...)); 

Close the Visual Studio and Run it as administrator. It's fixed my problem.

You should always include all relevant code when asking a question. In this case, the print statement that is the center of your question. The print statement is probably the most crucial piece of information. The second most crucial piece of information is the error, which you also did not include. Next time, include both of those.

print $ids should be a fairly hard statement to mess up, but it is possible. Possible reasons:

1. $ids is undefined. Gives the warning undefined value in print
2. $ids is out of scope. With use strict, gives fatal warning Global variable $ids needs explicit package name, and otherwise the undefined warning from above.
3. You forgot a semi-colon at the end of the line.
4. You tried to do print $ids $nIds, in which case perl thinks that $ids is supposed to be a filehandle, and you get an error such as print to unopened filehandle.

Explanations

1: Should not happen. It might happen if you do something like this (assuming you are not using strict):

my $var;
while (<>) {
    $Var .= $_;
}
print $var;

Gives the warning for undefined value, because $Var and $var are two different variables.

2: Might happen, if you do something like this:

if ($something) {
    my $var = "something happened!";
}
print $var;

my declares the variable inside the current block. Outside the block, it is out of scope.

3: Simple enough, common mistake, easily fixed. Easier to spot with use warnings.

4: Also a common mistake. There are a number of ways to correctly print two variables in the same print statement:

print "$var1 $var2";  # concatenation inside a double quoted string
print $var1 . $var2;  # concatenation
print $var1, $var2;   # supplying print with a list of args

Lastly, some perl magic tips for you:

use strict;
use warnings;

# open with explicit direction '<', check the return value
# to make sure open succeeded. Using a lexical filehandle.
open my $fh, '<', 'file.txt' or die $!;

# read the whole file into an array and
# chomp all the lines at once
chomp(my @file = <$fh>);
close $fh;

my $ids  = join(' ', @file);
my $nIds = scalar @file;
print "Number of lines: $nIds\n";
print "Text:\n$ids\n";

Reading the whole file into an array is suitable for small files only, otherwise it uses a lot of memory. Usually, line-by-line is preferred.

Variations:

• print "@file" is equivalent to $ids = join(' ',@file); print $ids;
• $#file will return the last index in @file. Since arrays usually start at 0, $#file + 1 is equivalent to scalar @file.

You can also do:

my $ids;
do {
    local $/;
    $ids = <$fh>;
}

By temporarily "turning off" $/, the input record separator, i.e. newline, you will make <$fh> return the entire file. What <$fh> really does is read until it finds $/, then return that string. Note that this will preserve the newlines in $ids.

Line-by-line solution:

open my $fh, '<', 'file.txt' or die $!; # btw, $! contains the most recent error
my $ids;
while (<$fh>) {
    chomp;
    $ids .= "$_ "; # concatenate with string
}
my $nIds = $.; # $. is Current line number for the last filehandle accessed.

try this:

$(document).ready(function() {
    $(document).find('input[type=number]').attr('type', 'tel');
});

Adding syntax highlighting for new languages to Eclipse with the Colorer library

Say you have an HRC file containing the syntax and lexical structure of some programming language Eclipse does not support (for example D / Iptables or any other script language).

Using the EclipseColorer plugin, you can easily add support for it.

Go to Help -> Install New Software and click Add.. In the Name field write Colorer and in the Location field write http://colorer.sf.net/eclipsecolorer/

Select the entry you’ve just added in the work with: combo box, wait for the component list to populate and click Select All

Click Next and follow the instructions

Once the plugin is installed, close Eclipse.

Copy your HRC file to [EclipseFolder]\plugins\net.sf.colorer_0.9.9\colorer\hrc\auto\types

[EclipseFolder] = /home/myusername/.eclipse

Use your favorite text editor to open

[EclipseFolder]\plugins\net.sf.colorer_0.9.9\colorer\hrc\auto\empty.hrc

Add the appropriate prototype element. For example, if your HRC file is d.hrc, empty.hrc will look like this:

<?xml version="1.0" encoding='Windows-1251'?>
 <!DOCTYPE hrc PUBLIC
 "-//Cail Lomecb//DTD Colorer HRC take5//EN"
 "http://colorer.sf.net/2003/hrc.dtd"
 >
 <hrc version="take5" xmlns="http://colorer.sf.net/2003/hrc"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://colorer.sf.net/2003/hrc http://colorer.sf.net/2003/hrc.xsd"
 ><annotation><documentation>
 'auto' is a place for include
 to colorer your own HRCs
</documentation></annotation>
    <prototype name="d" group="main" description="D">
         <location link="types/d.hrc"/>
        <filename>/\.(d)$/i</filename>
 </prototype>
</hrc>

Save the changes and close the text editor

Open Eclipse and go to Window -> Preferences -> General -> Editors -> File Associations

In the file types section, click Add.. and fill in the appropriate filetype (for example .d)

Click OK and click your newly added entry in the list

In the associated editors section, click Add.., select Colorer Editor and press OK

ok, the hard part is you must learn about HCR syntax.

You can look in

[EclipseFolder]/net.sf.colorer_0.9.9/colorer/hrc/common.jar

to learn how do it and explore many other hcr's files. At this moment I didn't find any documentation.

My gift is a basic and incomplete iptables syntax highlight. If you improve please share with me.

After this you must save the file as iptables.hcr and add inside the jar:

[EclipseFolder]/net.sf.colorer_0.9.9/colorer/hrc/common.jar

Based in: https://ohadsc.wordpress.com/2012/05/26/adding-syntax-highlighting-for-new-languages-to-eclipse-with-the-colorer-library/

In the right hand column under your solution explorer, you can see next to the reference to "Science" its marked as a warning. Either that means it cant find it, or its objecting to it for some other reason. While this is the case and your code requires it (and its not just in the references list) it wont compile.

Please post the warning message, we can try help you further.

Alternatively to what the others are correctly suggesting, I find it easier usually to toggle CSS classes, instead of individual CSS settings (especially background image URLs). For example:

// in CSS 
.bg1 
{
  background-image: url(/some/image/url/here.jpg);
}

.bg2 
{
  background-image: url(/another/image/url/there.jpg);
}

// in JS
// based on value of imageUrl, determine what class to remove and what class to add.
$('myOjbect').removeClass('bg1').addClass('bg2');

If your requirement is to maintain the insertion order plus check the contents of the two arraylist then you should do following:

List<String> listOne = new ArrayList<String>();
List<String> listTwo = new ArrayList<String>();

listOne.add("stack");
listOne.add("overflow");

listTwo.add("stack");
listTwo.add("overflow");

boolean result = Arrays.equals(listOne.toArray(),listTwo.toArray());

This will return true.

However, if you change the ordering for example:

listOne.add("stack");
listOne.add("overflow");

listTwo.add("overflow");
listTwo.add("stack");

boolean result = Arrays.equals(listOne.toArray(),listTwo.toArray());

will return false as ordering is different.

Recursive function :

            return getElementInsideElement(elementToReturn, wantedElementID);
        }

}

Hard to judge without the context of the page html or the rest of your CSS. There might be a zillion reasons why your CSS rule is not affecting the td element.

Have you tried more specific CSS selectors such as

tr.somethingontrlevel td.something {
  width: 90px;
}

This to avoid your CSS being overridden by a more specific rule from the bootstrap css.

(by the way, in your inline css sample with the style attribute, you misspelled width - that could explain why that try failed!)

pkill -f for whatever reason does not work for me. Whatever that does, it seems very finicky about actually grepping through what ps aux shows me clearly is there.

After an afternoon of swearing I went for putting the following in my start script:

(ps aux | grep -v -e 'grep ' | grep MainApp | tr -s " " | cut -d " " -f 2 | xargs kill -9 ) || true

I had this problem when moving my project from one computer to another. The solution was to reload selenium webdriver from nuget.

Edit: Coming back to this answer after a year of security research, I realize it makes the rather unfortunate implication that you would ever actually compare plaintext passwords. Please don't. Use a secure one-way hash with a salt and a reasonable number of iterations. Consider using a library: this stuff is hard to get right!

Original answer: What about the fact that String.equals() uses short-circuit evaluation, and is therefore vulnerable to a timing attack? It may be unlikely, but you could theoretically time the password comparison in order to determine the correct sequence of characters.

public boolean equals(Object anObject) {
    if (this == anObject) {
        return true;
    }
    if (anObject instanceof String) {
        String anotherString = (String)anObject;
        int n = value.length;
        // Quits here if Strings are different lengths.
        if (n == anotherString.value.length) {
            char v1[] = value;
            char v2[] = anotherString.value;
            int i = 0;
            // Quits here at first different character.
            while (n-- != 0) {
                if (v1[i] != v2[i])
                    return false;
                i++;
            }
            return true;
        }
    }
    return false;
}

I have created a filter. The filter can be used in any page.

Vue.filter('toCurrency', function (value) {
    if (typeof value !== "number") {
        return value;
    }
    var formatter = new Intl.NumberFormat('en-US', {
        style: 'currency',
        currency: 'USD',
        minimumFractionDigits: 0
    });
    return formatter.format(value);
});

Then I can use this filter like this:

        <td class="text-right">
            {{ invoice.fees | toCurrency }}
        </td>

I used these related answers to help with the implementation of the filter:

• How to format numbers as currency string?
• Check whether variable is number or string in JavaScript

You can select every column from that sub-query by aliasing it and adding the alias before the *:

SELECT t.*, a+b AS total_sum
FROM
(
   SELECT SUM(column1) AS a, SUM(column2) AS b
   FROM table
) t

Here's a version of @Julian Mosquera's code that also supports a "fallback" field to use in case the primary field happens to be null or undefined:

yourApp.filter('orderObjectBy', function() {
  return function(items, field, fallback, reverse) {
    var filtered = [];
    angular.forEach(items, function(item) {
      filtered.push(item);
    });
    filtered.sort(function (a, b) {
      var af = a[field];
      if(af === undefined || af === null) { af = a[fallback]; }

      var bf = b[field];
      if(bf === undefined || bf === null) { bf = b[fallback]; }

      return (af > bf ? 1 : -1);
    });
    if(reverse) filtered.reverse();
    return filtered;
  };
});

Because growthRates is a sequence (you're even iterating it!) and you multiply it by (1 + 0.01), which is obviously a float (1.01). I guess you mean for growthRate in growthRates: ... * growthrate?

This is one of those things that are missing. Your best bet is to create your own custom Navigation Bar, add a text box, and manipulate the color that way.

You can use text-align: center; line-height: 65px;

public - The members (Functions & Variables) declared as public can be accessed from anywhere.

private - Private members cannot be accessed from outside the class. This is the default access specifier for a member, i.e if you do not specify an access specifier for a member (variable or function), it will be considered as private. Therefore, string PhoneNumber; is equivalent to private string PhoneNumber.

protected - Protected members can be accessed only from the child classes.

internal - It can be accessed only within the same assembly.

protected internal - It can be accessed within the same assembly as well as in derived class.

I know this is an old topic but thought I would feed back in case it helps others. None of the answers to the question seem to work in IE8. I did however find this code that works in IE8. (Havent tested anything below IE8 yet). This can be easily modified for jQuery if required.

function capsCheck(e,obj){ 
    kc = e.keyCode?e.keyCode:e.which;  
    sk = e.shiftKey?e.shiftKey:((kc == 16)?true:false);  
    if(((kc >= 65 && kc <= 90) && !sk)||((kc >= 97 && kc <= 122) && sk)){
        document.getElementById('#'+obj.id).style.visibility = 'visible';
    } 
    else document.getElementById('#'+obj.id).style.visibility = 'hidden';
}

And the function is called through the onkeypress event like this:

<input type="password" name="txtPassword" onkeypress="capsCheck(event,this);" />
<div id="capsWarningDiv" style="visibility:hidden">Caps Lock is on.</div> 

There is one way to react to a kill -9: that is to have a separate process that monitors the process being killed and cleans up after it if necessary. This would probably involve IPC and would be quite a bit of work, and you can still override it by killing both processes at the same time. I assume it will not be worth the trouble in most cases.

Whoever kills a process with -9 should theoretically know what he/she is doing and that it may leave things in an inconsistent state.

The second one would be more efficient as it just has one predicate to evaluate against each item in the collection where as in the first one, it's applying the first predicate to all items first and the result (which is narrowed down at this point) is used for the second predicate and so on. The results get narrowed down every pass but still it involves multiple passes.

Also the chaining (first method) will work only if you are ANDing your predicates. Something like this x.Age == 10 || x.Fat == true will not work with your first method.

I've found, a better way to do this is to use CSS to remove pointer-events and modify the opacity on the drop down (try 0.5). This gives the appearance to the user that it is disabled as normal, but still posts data.

Granted this has some issues with backwards compatibility, but is in my opinion a better option than getting around the annoying disabled/readonly issue.

You can use flexbox for this.

ul {
    display: flex;
    align-items: center;
}

A detailed explanation of how to use flexbox can be found here.

I bet you have to install libxml2-devel or libxml++-devel or even python-devel. But it is only a wild guess, not seeing the actual error from the log file. But it seems gcc is missing either a header file or a library file.

I just created a simple application

What is the target processor of the application? I am guessing it is x86 - so either set it to x64 or anycpu.

I think the issue you are having is due to a 64bit process trying to access a 32bit dll.

Also, if you can't change the target processor you could try to enable 32-bit Applications from the Application Pools settings in IIS.

check this question and the selected answer: Stop EditText from gaining focus at Activity startup It's ugly but it works, and as far as I know there's no better solution.

An asynchronous way to create directories recursively:

import fs from 'fs'

const mkdirRecursive = function(path, callback) {
  let controlledPaths = []
  let paths = path.split(
    '/' // Put each path in an array
  ).filter(
    p => p != '.' // Skip root path indicator (.)
  ).reduce((memo, item) => {
    // Previous item prepended to each item so we preserve realpaths
    const prevItem = memo.length > 0 ? memo.join('/').replace(/\.\//g, '')+'/' : ''
    controlledPaths.push('./'+prevItem+item)
    return [...memo, './'+prevItem+item]
  }, []).map(dir => {
    fs.mkdir(dir, err => {
      if (err && err.code != 'EEXIST') throw err
      // Delete created directory (or skipped) from controlledPath
      controlledPaths.splice(controlledPaths.indexOf(dir), 1)
      if (controlledPaths.length === 0) {
        return callback()
      }
    })
  })
}

// Usage
mkdirRecursive('./photos/recent', () => {
  console.log('Directories created succesfully!')
})

The userdir prefix (e.g., '/home' or '/export/home') could be a configuration item. Then the app can append the arbitrary user name to that path.

Caveat: This doesn't intelligently interact with the OS, so you'd be out of luck if it were a Windows system with userdirs on different drives, or on Unix with a home dir layout like /home/f/foo, /home/b/bar.

targetList = list1.Concat(list2).ToList();

It's working fine I think so. As previously said, Concat returns a new sequence and while converting the result to List, it does the job perfectly.

In Windows 10 preview build with PowerShell 5, I can see that you can do:

$info = Get-Package -Name YourInstalledProduct
$info.Metadata["ProductCode"]

Not familiar with even not sure if all products has UpgradeCode, but according to this post you need to search UpgradeCode from this registry path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UpgradeCodes

Unfortunately, the registry key values are the ProductCode and the registry keys are the UpgradeCode.

For white Toolbar Title and White Up arrow, use following theme:

android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"

A very pythonic and practical way to do it is by using the string join() method:

str.join(iterable)

The official Python documentations says:

Return a string which is the concatenation of the strings in iterable... The separator between elements is the string providing this method.

How to use it?

Remember: this is a string method.

This method will be applied to the str above, which reflects the string that will be used as separator of the items in the iterable.

Let's have some practical example!

iterable = "BINGO"
separator = " " # A whitespace character.
                # The string to which the method will be applied
separator.join(iterable)
> 'B I N G O'

In practice you would do it like this:

iterable = "BINGO"    
" ".join(iterable)
> 'B I N G O'

But remember that the argument is an iterable, like a string, list, tuple. Although the method returns a string.

iterable = ['B', 'I', 'N', 'G', 'O']    
" ".join(iterable)
> 'B I N G O'

What happens if you use a hyphen as a string instead?

iterable = ['B', 'I', 'N', 'G', 'O']    
"-".join(iterable)
> 'B-I-N-G-O'

Look on my solution. I suppose that you should set selected position in holder and pass it as Tag of View. The view should be set in the onCreateViewHolder(...) method. There is also correct place to set listener for view such as OnClickListener or LongClickListener.

Please look on the example below and read comments to code.

public class MyListAdapter extends RecyclerView.Adapter<MyListAdapter.ViewHolder> {
    //Here is current selection position
    private int mSelectedPosition = 0;
    private OnMyListItemClick mOnMainMenuClickListener = OnMyListItemClick.NULL;

    ...

    // constructor, method which allow to set list yourObjectList

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        //here you prepare your view 
        // inflate it
        // set listener for it
        final ViewHolder result = new ViewHolder(view);
        final View view =  LayoutInflater.from(parent.getContext()).inflate(R.layout.your_view_layout, parent, false);
        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //here you set your current position from holder of clicked view
                mSelectedPosition = result.getAdapterPosition();

                //here you pass object from your list - item value which you clicked
                mOnMainMenuClickListener.onMyListItemClick(yourObjectList.get(mSelectedPosition));

                //here you inform view that something was change - view will be invalidated
                notifyDataSetChanged();
            }
        });
        return result;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        final YourObject yourObject = yourObjectList.get(position);

        holder.bind(yourObject);
        if(mSelectedPosition == position)
            holder.itemView.setBackgroundColor(Color.CYAN);
        else
            holder.itemView.setBackgroundColor(Color.RED);
    }

    // you can create your own listener which you set for adapter
    public void setOnMainMenuClickListener(OnMyListItemClick onMyListItemClick) {
        mOnMainMenuClickListener = onMyListItemClick == null ? OnMyListItemClick.NULL : onMyListItemClick;
    }

    static class ViewHolder extends RecyclerView.ViewHolder {


        ViewHolder(View view) {
            super(view);
        }

        private void bind(YourObject object){
            //bind view with yourObject
        }
    }

    public interface OnMyListItemClick {
        OnMyListItemClick NULL = new OnMyListItemClick() {
            @Override
            public void onMyListItemClick(YourObject item) {

            }
        };

        void onMyListItemClick(YourObject item);
    }
}

If you want to check selected option through javascript

Simplest method is add onchange attribute in that tag and define a function in js file see example if your html file has options something like this

 <select onchange="subjects(this.value)">
               <option>Select subject</option>
               <option value="Computer science">Computer science</option>
               <option value="Information Technolgy">Information Technolgy</option>
               <option value="Electronic Engineering">Electronic Engineering</option>
               <option value="Electrical Engineering">Electrical Engineering</option>
 </select>

And now add function in js file

function subjects(str){
    console.log(`selected option is ${str}`);
}

If you want to check selected option in php file

Simply give name attribute in your tag and access it php file global variables /array ($_GET or $_POST) see example if your html file is something like this

<form action="validation.php" method="POST">
             Subject:<br>
            <select name="subject">
               <option>Select subject</option>
               <option value="Computer science">Computer science</option>
               <option value="Information Technolgy">Information Technolgy</option>
               <option value="Electronic Engineering">Electronic Engineering</option>
               <option value="Electrical Engineering">Electrical Engineering</option>
            </select><br>

         </form>

And in your php file validation.php you can access like this

$subject = $_POST['subject'];
echo "selected option is $subject";

Here's the mysql reference for cursors. So I'm guessing it's something like this:

  DECLARE done INT DEFAULT 0;
  DECLARE products_id INT;
  DECLARE result varchar(4000);
  DECLARE cur1 CURSOR FOR SELECT products_id FROM sets_products WHERE set_id = 1;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;

  OPEN cur1;

  REPEAT
    FETCH cur1 INTO products_id;
    IF NOT done THEN
      CALL generate_parameter_list(@product_id, @result);
      SET param = param + "," + result; -- not sure on this syntax
    END IF;
  UNTIL done END REPEAT;

  CLOSE cur1;

  -- now trim off the trailing , if desired

On my MacOS Catalina machine I discovered that an additional file had been created at /etc/apache2/users/my-username.conf where the default was

AllowOverride none

Changing that to All finally got things working for me. The challenge with Mac is that its hard to get to these directories with Finder so its easy not to spot this file

NOTE: onKeyListener doesn't work for soft keyboards.

You can set OnKeyListener for you editText so you can detect any key press
EDIT: A common mistake we are checking KeyEvent.KEYCODE_BACK for backspace, but really it is KeyEvent.KEYCODE_DEL (Really that name is very confusing! )

editText.setOnKeyListener(new OnKeyListener() {                 
    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        //You can identify which key pressed buy checking keyCode value with KeyEvent.KEYCODE_
        if(keyCode == KeyEvent.KEYCODE_DEL) {  
            //this is for backspace
        }
        return false;       
    }
});

These are subplot grid parameters encoded as a single integer. For example, "111" means "1x1 grid, first subplot" and "234" means "2x3 grid, 4th subplot".

Alternative form for add_subplot(111) is add_subplot(1, 1, 1).

That's yet another question, which, being wrongly put, spawns A LOT of terrible solutions, all making things awfully complicated to solve a non-existent problem.

The extremely simple and obvious rule for any database interaction is

Always select the only data you need.

From this point of view, the question is wrong and the accepted answer is right. But other proposed solutions are just terrible.

The question is "how to get the count wrong way". One should never answer it straightforward, but instead, the only proper answer is "One should never select the rows to count them. Instead, ALWAYS ask the database to count the rows for you." This rule is so obvious, that it's just improbable to see so many tries to break it.

After learning this rule, we would see that this is an SQL question, not even PDO related. And, were it asked properly, from SQL perspective, the answer would appeared in an instant - DISTINCT.

$num = $db->query('SELECT count(distinct boele) FROM tbl WHERE oele = 2')->fetchColumn();

is the right answer to this particular question.

The opening poster's own solution is also acceptable from the perspective of the aforementioned rule, but would be less efficient in general terms.

Update: As @Soham Shetty comments, getSegmentsAtEvent(event) only works for 1.x and for 2.x getElementsAtEvent should be used.

.getElementsAtEvent(e)

Looks for the element under the event point, then returns all elements at the same data index. This is used internally for 'label' mode highlighting.

Calling getElementsAtEvent(event) on your Chart instance passing an argument of an event, or jQuery event, will return the point elements that are at that the same position of that event.

canvas.onclick = function(evt){
    var activePoints = myLineChart.getElementsAtEvent(evt);
    // => activePoints is an array of points on the canvas that are at the same position as the click event.
};

Example: https://jsfiddle.net/u1szh96g/208/

Original answer (valid for Chart.js 1.x version):

You can achieve this using getSegmentsAtEvent(event)

Calling getSegmentsAtEvent(event) on your Chart instance passing an argument of an event, or jQuery event, will return the segment elements that are at that the same position of that event.

From: Prototype Methods

So you can do:

$("#myChart").click( 
    function(evt){
        var activePoints = myNewChart.getSegmentsAtEvent(evt);           
        /* do something */
    }
);  

Here is a full working example:

                    color:"#F7464A",
                    highlight: "#FF5A5E",
                    label: "Red"
                },
                {
                    value: 50,

                    var myNewChart = new Chart(ctx).Pie(data);

                    $("#myChart").click( 
                        function(evt){
                            var activePoints = myNewChart.getSegmentsAtEvent(evt);
                            var url = "http://example.com/?label=" + activePoints[0].label + "&value=" + activePoints[0].value;
                            alert(url);
                        }
                    );                  
                }

Do this instead:

values = [[1,2,3],[4,5]]
for x in values:
    if len(x) == 3:
       print(x)

In addition to Nels Beckman's solution, I have the following tips:

Under Configure Build Path, I had to rearrange the order of my entries under Order and Export.

Additionally, as an Eclipse PDE developer, I needed to rearrange the order of my dependencies in my MANIFEST.MF, adding the problematic package as first on the list.

Playing with these dials, along with running Project > Clean in between, I was able to resolve these warnings.

// On the form: dow mon dd hh:mm:ss zzz yyyy

let image = UIImage(systemName: "envelope")
let textField = UITextField()
textField.leftView = UIImageView(image: image)
textField.leftView?.frame = CGRect(x: 5, y: 5, width: 20 , height:20)
textField.leftViewMode = .always

In continuing of the Apparently with Laravel 5.2, the closure in DB::listen only receives a single parameter... response above : you can put this code into the Middleware script and use it in the routes.

Additionally:

use Monolog\Handler\StreamHandler;

$log = new Logger('sql');
$log->pushHandler(new StreamHandler(storage_path().'/logs/sql-' . date('Y-m-d') . '.log', Logger::INFO));

// add records to the log
$log->addInfo($query, $data);

In short set cascade type to all , will do a job; For an example in your model. Add Code like this . @OneToMany(mappedBy = "receipt", cascade=CascadeType.ALL) private List saleSet;

Some handy script:

In my case, I was using Razor Views outside of a web application.
Copying the dlls to my bin folder in solution solved the problem.

Please read the example in rfc6749 sec 7.1 first.

The bearer token is a type of access token, which does NOT require PoP(proof-of-possession) mechanism.

PoP means kind of multi-factor authentication to make access token more secure. ref

Proof-of-Possession refers to Cryptographic methods that mitigate the risk of Security Tokens being stolen and used by an attacker. In contrast to 'Bearer Tokens', where mere possession of the Security Token allows the attacker to use it, a PoP Security Token cannot be so easily used - the attacker MUST have both the token itself and access to some key associated with the token (which is why they are sometimes referred to 'Holder-of-Key' (HoK) tokens).

Maybe it's not the case, but I would say,

From the Aspose Cells forums: How to use new line char with in a cell?

After you supply text you should set the cell's IsTextWrapped style to true

worksheet.Cells[0, 0].Style.WrapText = true;

I would just create a separate CSS class:

.ButtonClicked {
    background-color:red;
}

And then add the class on click:

$('#ButtonId').on('click',function(){
    !$(this).hasClass('ButtonClicked') ? addClass('ButtonClicked') : '';
});

This should do what you're looking for, showing by this jsFiddle. If you're curious about the logic with the ? and such, its called ternary (or conditional) operators, and its just a concise way to do the simple if logic to check if the class has already been added.

You can also create the ability to have an "on/off" switch feel by toggling the class:

$('#ButtonId').on('click',function(){
    $(this).toggleClass('ButtonClicked');
});

Shown by this jsFiddle. Just food for thought.

I've used an interesting conditional formatting in a recent file of mine and thought it would be useful to others too. So this answer is meant for completeness to the previous ones.

It should demonstrate what this amazing feature is capable of, and especially how the $ thing works.

Example table

The color from D to G depend on the values in columns A, B and C. But the formula needs to check values that are fixed horizontally (user, start, end), and values that are fixed vertically (dates in row 1). That's where the dollar sign gets useful.

Solution

There are 2 users in the table, each with a defined color, respectively foo (blue) and bar (yellow).
We have to use the following conditional formatting rules, and apply both of them on the same range (D2:G3):

1. =AND($A2="foo", D$1>=$B2, D$1<=$C2)
2. =AND($A2="bar", D$1>=$B2, D$1<=$C2)

In English, the condition means:
User is name, and date of current cell is after start and before end

Notice how the only thing that changes between the 2 formulas, is the name of the user. This makes it really easy to reuse with many other users!

Explanations

Important: Variable rows and columns are relative to the start of the range. But fixed values are not affected.

It is easy to get confused with relative positions. In this example, if we had used the range D1:G3 instead of D2:G3, the color formatting would be shifted 1 row up.
To avoid that, remember that the value for variable rows and columns should correspond to the start of the containing range.

In this example, the range that contains colors is D2:G3, so the start is D2.

User, start, and end vary with rows
-> Fixed columns A B C, variable rows starting at 2: $A2, $B2, $C2

Dates vary with columns
-> Variable columns starting at D, fixed row 1: D$1

Let me offer a more extensive answer considering things that you haven't mentioned as yet but will find useful.

For your current problem the answer is

$("div[id^='editDialog']");

The caret (^) is taken from regular expressions and means starts with.

Solution 1

// Select elems where 'attribute' ends with 'Dialog'
$("[attribute$='Dialog']"); 

// Selects all divs where attribute is NOT equal to value    
$("div[attribute!='value']"); 

// Select all elements that have an attribute whose value is like
$("[attribute*='value']"); 

// Select all elements that have an attribute whose value has the word foobar
$("[attribute~='foobar']"); 

// Select all elements that have an attribute whose value starts with 'foo' and ends
//  with 'bar'
$("[attribute^='foo'][attribute$='bar']");

attribute in the code above can be changed to any attribute that an element may have, such as href, name, id or src.

Solution 2

Use classes

// Matches all items that have the class 'classname'
$(".className");

// Matches all divs that have the class 'classname'
$("div.className");

Solution 3

List them (also noted in previous answers)

$("#id1,#id2,#id3");

Solution 4

For when you improve, regular expression (Never actually used these, solution one has always been sufficient, but you never know!

// Matches all elements whose id takes the form editDialog-{one_or_more_integers}
$('div').filter(function () {this.id.match(/editDialog\-\d+/)});

Datetime is just lovely if you like remembering funny codes. Wouldn't you prefer simplicity?

>>> import arrow
>>> arrow.now().format('YYYY-MM-DD')
'2017-02-17'

This module is clever enough to understand what you mean.

Just do pip install arrow.

Addendum: In answer to those who become exercised over this answer let me just say that arrow represents one of the alternative approaches to dealing with dates in Python. That's mostly what I meant to suggest.

For me worked flawles something like this

doStuff(

    document.getElementById("myCircle1") ,

    document.getElementById("myCircle2") ,

    document.getElementById("myCircle3") ,

    document.getElementById("myCircle4")

);

Turns out the Samsung file explorer uses a custom action. This is why I could see the Samsung file explorer when looking for a file from the samsung apps, but not from mine.

The action is "com.sec.android.app.myfiles.PICK_DATA"

I created a custom Activity Picker which displays activities filtering both intents.

A string can be checked with the below function:

function either_String_existor_not($str, $character) {
    if (strpos($str, $character) !== false) {
        return true;
    }
    return false;
}

With Python>3.5, using glob, . pointing to your current folder and looking for .txt files:

 python -c "import glob;[print(x) for x in glob.glob('./**/*txt', recursive=True)]"

For older versions of Python, you can install glob2

Swift has its own Date type. No need to use NSDate.

Creating a Date and Time in Swift

In Swift, dates and times are stored in a 64-bit floating point number measuring the number of seconds since the reference date of January 1, 2001 at 00:00:00 UTC. This is expressed in the Date structure. The following would give you the current date and time:

let currentDateTime = Date()

For creating other date-times, you can use one of the following methods.

Method 1

If you know the number of seconds before or after the 2001 reference date, you can use that.

let someDateTime = Date(timeIntervalSinceReferenceDate: -123456789.0) // Feb 2, 1997, 10:26 AM

Method 2

Of course, it would be easier to use things like years, months, days and hours (rather than relative seconds) to make a Date. For this you can use DateComponents to specify the components and then Calendar to create the date. The Calendar gives the Date context. Otherwise, how would it know what time zone or calendar to express it in?

// Specify date components
var dateComponents = DateComponents()
dateComponents.year = 1980
dateComponents.month = 7
dateComponents.day = 11
dateComponents.timeZone = TimeZone(abbreviation: "JST") // Japan Standard Time
dateComponents.hour = 8
dateComponents.minute = 34

// Create date from components
let userCalendar = Calendar(identifier: .gregorian) // since the components above (like year 1980) are for Gregorian
let someDateTime = userCalendar.date(from: dateComponents)

Other time zone abbreviations can be found here. If you leave that blank, then the default is to use the user's time zone.

Method 3

The most succinct way (but not necessarily the best) could be to use DateFormatter.

let formatter = DateFormatter()
formatter.dateFormat = "yyyy/MM/dd HH:mm"
let someDateTime = formatter.date(from: "2016/10/08 22:31")

The Unicode technical standards show other formats that DateFormatter supports.

Notes

See my full answer for how to display the date and time in a readable format. Also read these excellent articles:

• How to work with dates and times in Swift 3, part 1: Dates, Calendars, and DateComponents
• How to work with dates and times in Swift 3, part 2: DateFormatter
• How to work with dates and times in Swift 3, part 3: Date arithmetic

I think the best way is to simply use:

window.open("yourURL", '_blank');

MD5 encrypting is possible, but decrypting is still unknown (to me). However, there are many ways to compare these things.

1. Using compare methods like so:

   <?php
     $db_pass = $P$BX5675uhhghfhgfhfhfgftut/0;
     $my_pass = "mypass";
     if ($db_pass === md5($my_pass)) {
       // password is matched
     } else {
       // password didn't match
     }
   

2. Only for WordPress users. If you have access to your PHPMyAdmin, focus you have because you paste that hashing here: $P$BX5675uhhghfhgfhfhfgftut/0, WordPress user_pass is not only MD5 format it also uses utf8_mb4_cli charset so what to do?

   That's why I use another Approach if I forget my WordPress password I use

   I install other WordPress with new password :P, and I then go to PHPMyAdmin and copy that hashing from the database and paste that hashing to my current PHPMyAdmin password ( which I forget )

   EASY is use this :

   1. password = "ARJUNsingh@123"
   2. password_hasing = " $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1 "
   3. Replace your $P$BX5675uhhghfhgfhfhfgftut/0 with my $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1

I USE THIS APPROACH FOR MY SELF WHEN I DESIGN THEMES AND PLUGINS

WORDPRESS USE THIS

The only difference is that one can participate in multiple inheritance and other cannot.

The definition of an interface has changed over time. Do you think an interface just has method declarations only and are just contracts? What about static final variables and what about default definitions after Java 8?

Interfaces were introduced to Java because of the diamond problem with multiple inheritance and that's what they actually intend to do.

Interfaces are the constructs that were created to get away with the multiple inheritance problem and can have abstract methods, default definitions and static final variables.

See Why does Java allow static final variables in interfaces when they are only intended to be contracts?.

The simplest supported solution is to either use margin

.element {
  display: block;
  margin: 0px auto;
}

Or use a second container around the element that has this margin applied. This will somewhat have the effect of padding: 0px auto if it did exist.

CSS

.element_wrapper {
  display: block;
  margin: 0px auto;
}
.element {
  background: blue;
}

HTML

<div class="element_wrapper">
  <div class="element">
    Hello world
  </div>
</div>

Just use

$('#SelectBoxId option:selected').text(); For Getting text as listed

$('#SelectBoxId').val(); For Getting selected Index value

Here's an extension method using @ata answer as inspiration.

"hello-world123, 456".MakeAlphaNumeric(new char[]{'-'});// yields "hello-world123456"

or if you require additional characters other than hyphen...

"hello-world123, 456!?".MakeAlphaNumeric(new char[]{'-','!'});// yields "hello-world123456!"


public static class StringExtensions
{   
    public static string MakeAlphaNumeric(this string input, params char[] exceptions)
    {
        var charArray = input.ToCharArray();
        var alphaNumeric = Array.FindAll<char>(charArray, (c => char.IsLetterOrDigit(c)|| exceptions?.Contains(c) == true));
        return new string(alphaNumeric);
    }
}

Without seeing your code, it's hard to answer other than a stab in the dark. I would guess that the string you're passing to encodeURIComponent(), which is the correct method to use, is coming from the result of accessing the innerHTML property. The solution is to get the innerText/textContent property value instead:

var str, 
    el = document.getElementById("myUrl");

if ("textContent" in el)
    str = encodeURIComponent(el.textContent);
else
    str = encodeURIComponent(el.innerText);

If that isn't the case, you can use the replace() method to replace the HTML entity:

encodeURIComponent(str.replace(/&/g, "&"));

Don't fart around with inserting spaces. For one, older versions of IE won't know what you're talking about. Besides that, though, there are cleaner ways in general.

For colorless indents, use the text-indent property.

p { text-indent: 1em; }

JSFiddle demo

Edit:

If you want the space to be colored, you might consider adding a thick left border to the first letter. (I'd almost-but-not-quite say "instead", because the indent can be an issue if you use both. But it feels dirty to me to rely solely on the border to indent.) You can specify how far away, and how wide, the color is using the first letter's left margin/padding/border width.

p:first-letter { border-left: 1em solid red; }

Demo

I believe bind always tries to send an event parameter. Try:

self.entry_1.bind("<Return>", lambda event: self.calculate(self.buttonOut_1.grid_info(), 1))

You accept the parameter and never use it.

Remove all white spaces and create an fixed-size or immutable List (See asList API docs)

final String str = "dog, cat, bear, elephant, ..., giraffe";
List<String> list = Arrays.asList(str.replaceAll("\\s", "").split(","));
// result: [dog, cat, bear, elephant, ..., giraffe]

It is possible to also use replaceAll(\\s+", "") but maximum efficiency depends on the use case. (see @GurselKoca answer to Removing whitespace from strings in Java)

This calls exactly for the using the Maven JAR Plugin

For example, if you want to exclude everything under src/test/resources/ from the final jar, put this:

<build>

        <plugins>
            <!-- configure JAR build -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <version>2.3.1</version>
                <configuration>
                    <excludes>
                        <exclude>src/test/resources/**</exclude>
                    </excludes>
                </configuration>
            </plugin>

...

Files under src/test/resources/ will still be available on class-path, they just won't be in resulting JAR.

To answer your immutable question:

Collections.singletonList will create an immutable List. An immutable List (also referred to as an unmodifiable List) cannot have it's contents changed. The methods to add or remove items will throw exceptions if you try to alter the contents.

A singleton List contains only that item and cannot be altered.

You need to add overflow:auto to your parent div for it to encompass the inner floated div:

<div style="margin:0 auto;width: 960px; min-height: 100px; background-color:orange;overflow:auto">
    <div style="width:500px; height:200px; background-color:black; float:right">
    </div>
</div>

jsFiddle example

(set-face-attribute 'default nil :height 100)

The value is in 1/10pt, so 100 will give you 10pt, etc.

The folder being password protected has nothing to do with PHP!

The method being used is called "Basic Authentication". There are no cross-browser ways to "logout" from it, except to ask the user to close and then open their browser...

Here's how you you could do it in PHP instead (fully remove your Apache basic auth in .htaccess or wherever it is first):

login.php:

<?php
session_start();
//change 'valid_username' and 'valid_password' to your desired "correct" username and password
if (! empty($_POST) && $_POST['user'] === 'valid_username' && $_POST['pass'] === 'valid_password')
{
    $_SESSION['logged_in'] = true;
    header('Location: /index.php');
}
else
{
    ?>

    <form method="POST">
    Username: <input name="user" type="text"><br>
    Password: <input name="pass" type="text"><br><br>
    <input type="submit" value="submit">
    </form>

    <?php
}

index.php

<?php
session_start();
if (! empty($_SESSION['logged_in']))
{
    ?>

    <p>here is my super-secret content</p>
    <a href='logout.php'>Click here to log out</a>

    <?php
}
else
{
    echo 'You are not logged in. <a href="login.php">Click here</a> to log in.';
}

logout.php:

<?php
session_start();
session_destroy();
echo 'You have been logged out. <a href="/">Go back</a>';

Obviously this is a very basic implementation. You'd expect the usernames and passwords to be in a database, not as a hardcoded comparison. I'm just trying to give you an idea of how to do the session thing.

Hope this helps you understand what's going on.

That is because is does not exist, since it is bounded to Windows.

Use the standard functions from <stdio.h> instead, such as getc

The suggested ncurses library is good if you want to write console-based GUIs, but I don't think it is what you want.

In case performance is more important than readability and as long as your condition consists of simple arithmetic operations, you can use aggregation pipeline. First, use $project to calculate the left hand side of the condition (take all fields to left hand side). Then use $match to compare with a constant and filter. This way you avoid javascript execution. Below is my test in python:

import pymongo
from random import randrange

docs = [{'Grade1': randrange(10), 'Grade2': randrange(10)} for __ in range(100000)]

coll = pymongo.MongoClient().test_db.grades
coll.insert_many(docs)

Using aggregate:

%timeit -n1 -r1 list(coll.aggregate([
    {
        '$project': {
            'diff': {'$subtract': ['$Grade1', '$Grade2']},
            'Grade1': 1,
            'Grade2': 1
        }
    },
    {
        '$match': {'diff': {'$gt': 0}}
    }
]))

1 loop, best of 1: 192 ms per loop

Using find and $where:

%timeit -n1 -r1 list(coll.find({'$where': 'this.Grade1 > this.Grade2'}))

1 loop, best of 1: 4.54 s per loop

That is an HTTP header. You would configure your webserver or webapp to send this header ideally. Perhaps in htaccess or PHP.

Alternatively you might be able to use

<head>...<meta http-equiv="Access-Control-Allow-Origin" content="*">...</head>

I do not know if that would work. Not all HTTP headers can be configured directly in the HTML.

This works as an alternative to many HTTP headers, but see @EricLaw's comment below. This particular header is different.

Caveat

This answer is strictly about how to set headers. I do not know anything about allowing cross domain requests.

About HTTP Headers

Every request and response has headers. The browser sends this to the webserver

GET /index.htm HTTP/1.1

Then the headers

Host: www.example.com
User-Agent: (Browser/OS name and version information)
.. Additional headers indicating supported compression types and content types and other info

Then the server sends a response

Content-type: text/html
Content-length: (number of bytes in file (optional))
Date: (server clock)
Server: (Webserver name and version information)

Additional headers can be configured for example Cache-Control, it all depends on your language (PHP, CGI, Java, htaccess) and webserver (Apache, etc).

This works for me https://www.nuget.org/packages/ASquare.WindowsTaskScheduler/

It is nicely designed Fluent API.

//This will create Daily trigger to run every 10 minutes for a duration of 18 hours
SchedulerResponse response = WindowTaskScheduler
    .Configure()
    .CreateTask("TaskName", "C:\\Test.bat")
    .RunDaily()
    .RunEveryXMinutes(10)
    .RunDurationFor(new TimeSpan(18, 0, 0))
    .SetStartDate(new DateTime(2015, 8, 8))
    .SetStartTime(new TimeSpan(8, 0, 0))
    .Execute();

From .Net 3.5 you can use LINQ extension method that (sometimes) makes code flow a bit better.

Usage looks like this:

using System.Linq; 

// ...

public void My()
{
    var myArray = new[] { "abc", "123", "zyx" };
    List<string> myList = myArray.ToList();
}

PS. There's also ToArray() method that works in other way.

I just executed connection.close() by adding it as first statement and it was solved. Then i removed the line.

for jQuery we can use below:

by input name:

$('input[name="textboxname"]').val('some value');

by input class:

$('input[type=text].textboxclass').val('some value');

by input id:

$('#textboxid').val('some value');

I'm posting this solution because I had a hard time finding what I needed. This post got me close enough (+1 for that thank you), and here is the final solution for rearranging column data before insert if the data matches a test.

Note: this is from a legacy project I inherited where:

1. The Unique Key is a composite of rridprefix + rrid
2. Before I took over there was no constraint preventing duplicate unique keys
3. We needed to combine two tables (one full of duplicates) into the main table which now has the constraint on the composite key (so merging fails because the gaining table won't allow the duplicates from the unclean table)
4. on duplicate key is less than ideal because the columns are too numerous and may change

Anyway, here is the trigger that puts any duplicate keys into a legacy column while allowing us to store the legacy, bad data (and not trigger the gaining tables composite, unique key).

BEGIN
  -- prevent duplicate composite keys when merging in archive to main
  SET @EXIST_COMPOSITE_KEY = (SELECT count(*) FROM patientrecords where rridprefix = NEW.rridprefix and rrid = NEW.rrid);

  -- if the composite key to be introduced during merge exists, rearrange the data for insert
  IF @EXIST_COMPOSITE_KEY > 0
  THEN

    -- set the incoming column data this way (if composite key exists)

    -- the legacy duplicate rrid field will help us keep the bad data
    SET NEW.legacyduperrid = NEW.rrid;

    -- allow the following block to set the new rrid appropriately
    SET NEW.rrid = null;

  END IF;

  -- legacy code tried set the rrid (race condition), now the db does it
  SET NEW.rrid = (
    SELECT if(NEW.rrid is null and NEW.legacyduperrid is null, IFNULL(MAX(rrid), 0) + 1, NEW.rrid)
    FROM patientrecords
    WHERE rridprefix  = NEW.rridprefix
  );
END

For both Python 2 and 3:

import six

six.next(six.itervalues(d))

Using Jquery and sending the data with ajax, you can solve your problem:

<script>

$('#form_id').submit(function() {
    $("#input_disabled_id").prop('disabled', false);

    //Rest of code
    })
</script>

You don't say what class you are using, but I'm guessing it is the standard book. In which case the page clearing is a feature of he class which you can override as Mica suggests, or solve by switching to another class. The standard report class is similar to book, or the memoir class is an improved book and is very flexible indeed.

Considering that you are using OpenCV, the best way to convert between data types is to use normalize function.

img_n = cv2.normalize(src=img, dst=None, alpha=0, beta=255, norm_type=cv2.NORM_MINMAX, dtype=cv2.CV_8U)

However, if you don't want to use OpenCV, you can do this in numpy

def convert(img, target_type_min, target_type_max, target_type):
    imin = img.min()
    imax = img.max()

    a = (target_type_max - target_type_min) / (imax - imin)
    b = target_type_max - a * imax
    new_img = (a * img + b).astype(target_type)
    return new_img

And then use it like this

imgu8 = convert(img16u, 0, 255, np.uint8)

This is based on the answer that I found on crossvalidated board in comments under this solution https://stats.stackexchange.com/a/70808/277040

I was facing this issue on a react-native project and it came after adding a splash screen activity and making it the launcher activity.

This is the change i made in my android manifest XML file on the MainActivity configuration.

<activity_x000D_
        android:name=".MainActivity"_x000D_
        android:label="@string/app_name"_x000D_
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize"_x000D_
        android:windowSoftInputMode="adjustResize"/>_x000D_
      <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />

I added the android:exported=true and the activity configuration looked like this.

 <activity_x000D_
        android:name=".MainActivity"_x000D_
        android:exported="true"_x000D_
        android:label="@string/app_name"_x000D_

      <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />_x000D_
   

An example that uses RecursiveDirectoryIterator class, it's a convenient way to iterate recursively over filesystem.

$output = array();
foreach( new RecursiveIteratorIterator( 
    new RecursiveDirectoryIterator( 'path', FilesystemIterator::SKIP_DOTS | FilesystemIterator::UNIX_PATHS ) ) as $value ) {      
        if ( $value->isFile() ) {
            $output[] = array( $value->getMTime(), $value->getRealPath() );
        }
}

usort ( $output, function( $a, $b ) {
    return $a[0] > $b[0];
});

You need to install a so-called Instance of MSSQL server on your computer. That is, installing all the needed files and services and database files. By default, there should be no MSSQL Server installed on your machine, assuming that you use a desktop Windows (7,8,10...).

You can start off with Microsoft SQL Server Express, which is a 10GB-limited, free version of MSSQL. It also lacks some other features (Server Agents, AFAIR), but it's good for some experiments.

Download it from the Microsoft Website and go through the installer process by choosing New SQL Server stand-alone installation .. after running the installer.

Click through the steps. For your scenario (it sounds like you mainly want to test some stuff), the default options should suffice.

Just give attention to the step Instance Configuration. There you will set the name of your MSSQL Server Instance. Call it something unique/descriptive like MY_TEST_INSTANCE or the like. Also, choose wisely the Instance root directory. In it, the database files will be placed, so it should be on a drive that has enough space.

Click further through the wizard, and when it's finished, your MSSQL instance will be up and running. It will also run at every boot if you have chosen the default settings for the services.

As soon as it's running in the background, you can connect to it with Management Studio by connecting to .\MY_TEST_INSTANCE, given that that's the name you chose for the instance.

You should read Supporting multiple screens. You must define dpi on your emulator. 240 is hdpi, 160 is mdpi and below that are usually ldpi.

Extract from Android Developer Guide link above:

320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).  
480dp: a tweener tablet like the Streak (480x800 mdpi).  
600dp: a 7” tablet (600x1024 mdpi).  
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).

just follow three steps, git branch problem will be solved.

git remote update
git fetch
git checkout --track origin/test-branch

Click on "Tables" in "Connections" window, choose "Import data ...", follow the wizard and you will be asked for name for new table.

1. Make sure session_start(); is called before any sessions are being called. So a safe bet would be to put it at the beginning of your page, immediately after the opening <?php tag before anything else. Also ensure there are no whitespaces/tabs before the opening <?php tag.
2. After the header redirect, end the current script using exit(); (Others have also suggested session_write_close(); and session_regenerate_id(true), you can try those as well, but I'd use exit();).
3. Make sure cookies are enabled in the browser you are using to test it on.
4. Ensure register_globals is off, you can check this on the php.ini file and also using phpinfo(). Refer to this as to how to turn it off.
5. Make sure you didn't delete or empty the session.
6. Make sure the key in your $_SESSION superglobal array is not overwritten anywhere.
7. Make sure you redirect to the same domain. So redirecting from a www.yourdomain.com to yourdomain.com doesn't carry the session forward.
8. Make sure your file extension is .php (it happens!).

PHP session lost after redirect

You can install unix2dos with Homebrew

brew install unix2dos

Then you can do this:

unix2dos file-to-convert

You can also convert dos files to unix:

dos2unix file-to-convert

Though you may prefer the pure Python solution provided by the python-daemon module, there is a daemon(3) function in libc -- at least, on BSD and Linux -- which will do the right thing.

Calling it from python is easy:

import ctypes

ctypes.CDLL(None).daemon(0, 0) # Read the man-page for the arguments' meanings

The only remaining thing to do is creation (and locking) of the PID-file. But that you can handle yourself...

Decode and save image as PNG

header('content-type: image/png');

           ob_start();

        $ret = fopen($fullurl, 'r', true, $context);
        $contents = stream_get_contents($ret);
        $base64 = 'data:image/PNG;base64,' . base64_encode($contents);
        echo "<img src=$base64 />" ;


        ob_end_flush();

You shouldn't do that and that's not possible anyway, If you want you can set a greater value such as 10 years ahead.

By the way, I have never seen a cookie with such requirement :)

A class cast exception is thrown by Java when you try to cast an Object of one data type to another.

Java allows us to cast variables of one type to another as long as the casting happens between compatible data types.

For example you can cast a String as an Object and similarly an Object that contains String values can be cast to a String.

Example

Let us assume we have an HashMap that holds a number of ArrayList objects.

If we write code like this:

String obj = (String) hmp.get(key);

it would throw a class cast exception, because the value returned by the get method of the hash map would be an Array list, but we are trying to cast it to a String. This would cause the exception.

With this code you will be also able to get MacAddress in Android 6.0 also

public static String getMacAddr() {
    try {
        List <NetworkInterface> all = Collections.list(NetworkInterface.getNetworkInterfaces());
        for (NetworkInterface nif: all) {
            if (!nif.getName().equalsIgnoreCase("wlan0")) continue;

            byte[] macBytes = nif.getHardwareAddress();
            if (macBytes == null) {
                return "";
            }

            StringBuilder res1 = new StringBuilder();
            for (byte b: macBytes) {
                //res1.append(Integer.toHexString(b & 0xFF) + ":");
                res1.append(String.format("%02X:", b));
            }

            if (res1.length() > 0) {
                res1.deleteCharAt(res1.length() - 1);
            }
            return res1.toString();
        }
    } catch (Exception ex) {}
    return "02:00:00:00:00:00";
}

EDIT 1. This answer got a bug where a byte that in hex form got a single digit, will not appear with a "0" before it. The append to res1 has been changed to take care of it.

It should be while(true) not while(1), so while(1) is incorrect in C#, yes ;)

Use $('#id-of-the-checkbox').prop('checked', true_or_false);

In case you are using an ancient jQuery version, you'll need to use .attr('checked', 'checked') to check and .removeAttr('checked') to uncheck.

As we all know storing password in clear text in database is not secure. the bcrypt is a hashing password technique.It is used to built password security. one of the amazing function of bcrypt is it save us from hackers it is used to protect the password from hacking attacks because the password is stored in bcrypted form.

the password_hash() function is used to create a new password hash. It uses a strong & robust hashing algorithm.The password_hash() function is very much compatible with the crypt() function. Therefore, password hashes created by crypt() may be used with password_hash() and vice-versa. The functions password_verify() and password_hash() just the wrappers around the function crypt(), and they make it much easier to use it accurately.

SYNTAX

string password_hash($password , $algo , $options)

The following algorithms are currently supported by password_hash() function:

PASSWORD_DEFAULT PASSWORD_BCRYPT PASSWORD_ARGON2I PASSWORD_ARGON2ID

Parameters: This function accepts three parameters as mentioned above and described below:

password: It stores the password of the user. algo: It is the password algorithm constant that is used continuously while denoting the algorithm which is to be used when the hashing of password takes place. options: It is an associative array, which contains the options. If this is removed and doesn’t include, a random salt is going to be used, and the utilization of a default cost will happen. Return Value: It returns the hashed password on success or False on failure.

Example:

Input : echo password_hash("GFG@123", PASSWORD_DEFAULT); Output : $2y$10$.vGA19Jh8YrwSJFDodbfoHJIOFH)DfhuofGv3Fykk1a

Below programs illustrate the password_hash() function in PHP:

<?php echo password_hash("GFG@123", PASSWORD_DEFAULT); ?>

OUTPUT

$2y$10$Z166W1fBdsLcXPVQVfPw/uRq1ueWMA6sLt9bmdUFz9AmOGLdM393G

Simply throw Exception if input is invalid

Scanner sc=new Scanner(System.in);
try
{
  System.out.println("Please input an integer");
  //nextInt will throw InputMismatchException
  //if the next token does not match the Integer
  //regular expression, or is out of range
  int usrInput=sc.nextInt();
}
catch(InputMismatchException exception)
{
  //Print "This is not an integer"
  //when user put other than integer
  System.out.println("This is not an integer");
}

You can use this for 24 hour to 12 hour:

echo date("h:i", strtotime($time));

And for vice versa:

echo date("H:i", strtotime($time));

I feel like this has been well covered, maybe except for the following:

• Simple KEY / INDEX (or otherwise called SECONDARY INDEX) do increase performance if selectivity is sufficient. On this matter, the usual recommendation is that if the amount of records in the result set on which an index is applied exceeds 20% of the total amount of records of the parent table, then the index will be ineffective. In practice each architecture will differ but, the idea is still correct.

• Secondary Indexes (and that is very specific to mysql) should not be seen as completely separate and different objects from the primary key. In fact, both should be used jointly and, once this information known, provide an additional tool to the mysql DBA: in Mysql, indexes embed the primary key. It leads to significant performance improvements, specifically when cleverly building implicit covering indexes such as described there.

• If you feel like your data should be UNIQUE, use a unique index. You may think it's optional (for instance, working it out at application level) and that a normal index will do, but it actually represents a guarantee for Mysql that each row is unique, which incidentally provides a performance benefit.

• You can only use FULLTEXT (or otherwise called SEARCH INDEX) with Innodb (In MySQL 5.6.4 and up) and Myisam Engines

• You can only use FULLTEXT on CHAR, VARCHAR and TEXT column types

• FULLTEXT index involves a LOT more than just creating an index. There's a bunch of system tables created, a completely separate caching system and some specific rules and optimizations applied. See http://dev.mysql.com/doc/refman/5.7/en/fulltext-restrictions.html and http://dev.mysql.com/doc/refman/5.7/en/innodb-fulltext-index.html

You can target that div from your stylesheet in a number of ways.

Simply use

.col-md-6:first-child {
  background-color: blue;
}

Another way is to assign a class to one div and then apply the style to that class.

<div class="col-md-6 blue"></div>

.blue {
  background-color: blue;
}

There are also inline styles.

<div class="col-md-6" style="background-color: blue"></div>

Your example code works fine to me. I'm not sure if I undestand what you intend to do, but if you want a blue background on the second div just remove the bg-primary class from the section and add you custom class to the div.

.blue {_x000D_
  background-color: blue;_x000D_
}

I know this a very much late reply but I saw this query recently And found a working scenario,

OnClick of Submit use the below code:

 $('#Submit').click(function ()
 { $(this).html('<img src="icon-loading.gif" />'); // A GIF Image of Your choice
 return false });

To Stop the Gif use the below code:

$('#Submit').ajaxStop();

Not exactly the case of actual context of this question, but this exception can be reproduced by the next query:

update users set dismissal_reason='he can't and don't want' where userid=123

Single quotes in words can't and don't broke the string. In case string have only one inside quote e.g. 'he don't want' oracle throws more relevant quoted string not properly terminated error, but in case of two SQL command not properly ended is thrown.

Summary: check your query for double single quotes.

I guess this would rather be a better solution.

Override the following methods as below mentioned in

App\Http\Controller\Auth\RegisterController.php

use Illuminate\Http\Response;

.
.
.

public function showRegistrationForm()
{
    abort(Response::HTTP_NOT_FOUND);
}

public function register(Request $request)
{
    abort(Response::HTTP_NOT_FOUND);
}

The .BAK files from SQL server are in Microsoft Tape Format (MTF) ref: http://www.fpns.net/willy/msbackup.htm

The bak file will probably contain the LDF and MDF files that SQL server uses to store the database.

You will need to use SQL server to extract these. SQL Server Express is free and will do the job.

So, install SQL Server Express edition, and open the SQL Server Powershell. There execute sqlcmd -S <COMPUTERNAME>\SQLExpress (whilst logged in as administrator)

then issue the following command.

restore filelistonly from disk='c:\temp\mydbName-2009-09-29-v10.bak';
GO

This will list the contents of the backup - what you need is the first fields that tell you the logical names - one will be the actual database and the other the log file.

RESTORE DATABASE mydbName FROM disk='c:\temp\mydbName-2009-09-29-v10.bak'
WITH 
   MOVE 'mydbName' TO 'c:\temp\mydbName_data.mdf', 
   MOVE 'mydbName_log' TO 'c:\temp\mydbName_data.ldf';
GO

At this point you have extracted the database - then install Microsoft's "Sql Web Data Administrator". together with this export tool and you will have an SQL script that contains the database.

The JSON you posted looks fine, however in your code, it is most likely not a JSON string anymore, but already a JavaScript object. This means, no more parsing is necessary.

You can test this yourself, e.g. in Chrome's console:

new Object().toString()
// "[object Object]"

JSON.parse(new Object())
// Uncaught SyntaxError: Unexpected token o in JSON at position 1

JSON.parse("[object Object]")
// Uncaught SyntaxError: Unexpected token o in JSON at position 1

JSON.parse() converts the input into a string. The toString() method of JavaScript objects by default returns [object Object], resulting in the observed behavior.

Try the following instead:

var newData = userData.data.userList;

| is a metacharacter in regex. You'd need to escape it:

String[] value_split = rat_values.split("\\|");

Change the content type to ms-excel in the html and browser shall open the html in the Excel as xls. If you want control over the transformation of HTML to excel use POI libraries to do so.

Building on the answers above, I am using this native one liner to convert the long timezone string to the three letter string:

var longTz = 'America/Los_Angeles';
var shortTz = new Date().
    toLocaleString("en", {timeZoneName: "short", timeZone: longTz}).
    split(' ').
    pop();

This will give PDT or PST depending on the date provided. In my particular use case, developing on Salesforce (Aura/Lightning), we are able to get the user timezone in the long format from the backend.

I had some weird errors where it could not find my class, I had to right click on my src folder (was red) to "Make Directory as" -> Source Folder Root

Try this: http://cairosvg.org/

The site says:

CairoSVG is written in pure python and only depends on Pycairo. It is known to work on Python 2.6 and 2.7.

Update November 25, 2016:

2.0.0 is a new major version, its changelog includes:

• Drop Python 2 support

Found this example... Will test...

import java.text.DecimalFormat;
class TestingAndQualityAssuranceDepartment
{
    public static void main(String [] args)
    {
        int x=1;
        DecimalFormat df = new DecimalFormat("00");
        System.out.println(df.format(x));
    }
}

Tested this and:

String.format("%05d",number);

Both work, for my purposes I think String.Format is better and more succinct.

probleme : unit test result are not the same runing with eclipse and maven due ti order of library used by eclipse and maven. In my case the test was success with maven but i want to debug my unit test using eclipse, so the most easy way to debug unit test class with eclipse and runing maven is :

1) mvn -Dtest=MySuperClassTest -Dmaven.surefire.debug test ==> it will listen to the 5005 port (default port)

2) Go to eclipse, open a debug configuration, add a new java remote application and change the port to 5005 and debug

3) of course you must add break point somewhere in the class that you want to debug

That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:

DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87

Double check your table definition. Maybe you just missed adding something.

I also tried google-ing this problem and saw this:

http://www.coderanch.com/t/515475/JDBC/databases/sql-insert-statement-giving-sqlcode

Instead of setting height property, use min-height.

Put them into a list and use merge with Reduce

Reduce(function(x, y) merge(x, y, all=TRUE), list(df1, df2, df3))
#    id v1 v2 v3
# 1   1  1 NA NA
# 2  10  4 NA NA
# 3   2  3  4 NA
# 4  43  5 NA NA
# 5  73  2 NA NA
# 6  23 NA  2  1
# 7  57 NA  3 NA
# 8  62 NA  5  2
# 9   7 NA  1 NA
# 10 96 NA  6 NA

You can also use this more concise version:

Reduce(function(...) merge(..., all=TRUE), list(df1, df2, df3))

Here's what's this TS snippet compiled into (via TS Playground):

define(["require", "exports"], function(require, exports) {
    var Library = (function () {
        function Library() {
        }
        Library.BOOK_SHELF_NONE = "None";
        Library.BOOK_SHELF_FULL = "Full";
        return Library;
    })();
    exports.Library = Library;
});

As you see, both properties defined as public static are simply attached to the exported function (as its properties); therefore they should be accessible as long as you properly access the function itself.

Try following steps:

1. delete the IISExpress folder as @Yehuda Shapira said
2. restart computer
3. delete the .vs folder in project

Have a good luck!

curl 7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.19.1 Basic ECC zlib/1.2.3 libidn/1.18 libssh2/1.4.2

You are using a very old version of curl. My guess is that you run into the bug described 6 years ago. Fix is to update your curl.

As far as i understand fr is the object of your FileReadExample class. So it is obvious it will not have any method like fr.readLine() if you dont create one yourself.

secondly, i think a correct constructor of the BufferedReader class will help you do your task.

String str;
BufferedReader buffread = new BufferedReader(new FileReader(new File("file.dat")));
str = buffread.readLine();
.
.
buffread.close();

this should help you.

I had a number of errors similar to this. Make sure your setFrom email address is valid in $mail->setFrom()

Yet another implementation using awk with a little more flexibility.

function parse_ini() {
  cat /dev/stdin | awk -v section="$1" -v key="$2" '
    BEGIN {
      if (length(key) > 0) { params=2 }
      else if (length(section) > 0) { params=1 }
      else { params=0 }
    }
    match($0,/#/) { next }
    match($0,/^\[(.+)\]$/){
      current=substr($0, RSTART+1, RLENGTH-2)
      found=current==section
      if (params==0) { print current }
    }
    match($0,/(.+)=(.+)/) {
       if (found) {
         if (params==2 && key==$1) { print $3 }
         if (params==1) { printf "%s=%s\n",$1,$3 }
       }
    }'
}

You can use calling passing between 0 and 2 params:

cat myfile1.ini myfile2.ini | parse_ini # List section names

cat myfile1.ini myfile2.ini | parse_ini 'my-section' # Prints keys and values from a section

cat myfile1.ini myfile2.ini | parse_ini 'my-section' 'my-key' # Print a single value

extension String{
// to make text field mandatory * looks
mutating func markAsMandatoryField()-> NSAttributedString{

    let main_string = self
    let string_to_color = "*"
    let range = (main_string as NSString).range(of: string_to_color)
    print("The rang = \(range)")
    let attribute = NSMutableAttributedString.init(string: main_string)
    attribute.addAttribute(NSAttributedString.Key.foregroundColor, value: UIColor.rgbColor(red: 255.0, green: 0.0, blue: 23.0) , range: range)
     return attribute
}

}

use EmailLbl.attributedText = EmailLbl.text!.markAsMandatoryField()

Using Pillow (which works with Python 3.X as well as Python 2.7+), you can do the following:

from PIL import Image
im = Image.open('image.jpg', 'r')
width, height = im.size
pixel_values = list(im.getdata())

Now you have all pixel values. If it is RGB or another mode can be read by im.mode. Then you can get pixel (x, y) by:

pixel_values[width*y+x]

Alternatively, you can use Numpy and reshape the array:

>>> pixel_values = numpy.array(pixel_values).reshape((width, height, 3))
>>> x, y = 0, 1
>>> pixel_values[x][y]
[ 18  18  12]

A complete, simple to use solution is

# Third party modules
import numpy
from PIL import Image


def get_image(image_path):
    """Get a numpy array of an image so that one can access values[x][y]."""
    image = Image.open(image_path, "r")
    width, height = image.size
    pixel_values = list(image.getdata())
    if image.mode == "RGB":
        channels = 3
    elif image.mode == "L":
        channels = 1
    else:
        print("Unknown mode: %s" % image.mode)
        return None
    pixel_values = numpy.array(pixel_values).reshape((width, height, channels))
    return pixel_values


image = get_image("gradient.png")

print(image[0])
print(image.shape)

Smoke testing the code

You might be uncertain about the order of width / height / channel. For this reason I've created this gradient:

The image has a width of 100px and a height of 26px. It has a color gradient going from #ffaa00 (yellow) to #ffffff (white). The output is:

[[255 172   5]
 [255 172   5]
 [255 172   5]
 [255 171   5]

(100, 26, 3)

Things to note:

• The shape is (width, height, channels)
• The image[0], hence the first row, has 26 triples of the same color

It might be the JavaScript check for some valid condition.
Two things you can perform a/c to your requirements:

1. either check for the valid string-input in the text-box.
2. or set a loop against that text box to enter the value until you post the form/request.

String barcode="0000000047166";

WebElement strLocator = driver.findElement(By.xpath("//*[@id='div-barcode']"));
strLocator.sendKeys(barcode);

-Filter only accepts a single string. -Include accepts multiple values, but qualifies the -Path argument. The trick is to append \* to the end of the path, and then use -Include to select multiple extensions. BTW, quoting strings is unnecessary in cmdlet arguments unless they contain spaces or shell special characters.

Get-ChildItem $originalPath\* -Include *.gif, *.jpg, *.xls*, *.doc*, *.pdf*, *.wav*, .ppt*

Note that this will work regardless of whether $originalPath ends in a backslash, because multiple consecutive backslashes are interpreted as a single path separator. For example, try:

Get-ChildItem C:\\\\\Windows

To inspect the error message and do something with it (with Python 3)...

try:
    some_method()

    if {value} in e.args:
        {do something}

the advantage of this way is you can set each column width independant of the other as long as you keep it under 100%, if you use 3 x 30% the remaining 10% is split as a 5% divider space between the collumns

This error happen usually when tables in the query doesn't exist. Just check the table's spelling in the query, and it will work.

What about?

public enum MyEnum {
    FIRST,
    SECOND,
    THIRD;

    public static Optional<MyEnum> fromString(String value){
        try{
            return Optional.of(MyEnum.valueOf(value));
        }catch(Exception e){
            return Optional.empty();
        }
    }
}

It sounds like you're looking for applicationHost.config, which is located in C:\Windows\System32\inetsrv\config.

Yes, it's an XML file, and yes, editing the file by hand will affect the IIS config after a restart. You can think of IIS Manager as a GUI front-end for editing applicationHost.config and web.config.

Try this

function removeElements(){
    $('#models').html("");
}

I think you can use the onclick event, something like this:

<a onclick="jsFunction();">

so do the following edit my.cnf:

[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
language = /usr/share/mysql/English
bind-address = xxx.xxx.xxx.xxx
# skip-networking

after edit hit service mysqld restart

login into mysql and hit this query:

GRANT ALL ON foo.* TO bar@'xxx.xxx.xxx.xxx' IDENTIFIED BY 'PASSWORD';

thats it make sure your iptables allow connection from 3306 if not put the following:

iptables -A INPUT -i lo -p tcp --dport 3306 -j ACCEPT

iptables -A OUTPUT -p tcp --sport 3306 -j ACCEPT

Types are dependent to your initialization:

var IsLoggedIn1 = "true"; //string
var IsLoggedIn2 = 1; //integer
var IsLoggedIn3 = true; //bool

But take a look at this example:

var IsLoggedIn1 = "true"; //string
IsLoggedIn1 = true; //now your variable is a boolean

Your variables' type depends on the assigned value in JavaScript.

Use the quotemeta function:

$text_to_search = "example text with [foo] and more";
$search_string = quotemeta "[foo]";

print "wee" if ($text_to_search =~ /$search_string/);

Overview

@Mike's answer is correct but too imprecise. It is true that Python 3.3+ supports Implicit Namespace Packages that allows it to create a package without an __init__.py file. This is called a namespace package in contrast to a regular package which does have an __init__.py file (empty or not empty).

However, creating a namespace package should ONLY be done if there is a need for it. For most use cases and developers out there, this doesn't apply so you should stick with EMPTY __init__.py files regardless.

Namespace package use case

To demonstrate the difference between the two types of python packages, lets look at the following example:

google_pubsub/              <- Package 1
    google/                 <- Namespace package (there is no __init__.py)
        cloud/              <- Namespace package (there is no __init__.py)
            pubsub/         <- Regular package (with __init__.py)
                __init__.py <- Required to make the package a regular package
                foo.py

google_storage/             <- Package 2
    google/                 <- Namespace package (there is no __init__.py)
        cloud/              <- Namespace package (there is no __init__.py)
            storage/        <- Regular package (with __init__.py)
                __init__.py <- Required to make the package a regular package
                bar.py

google_pubsub and google_storage are separate packages but they share the same namespace google/cloud. In order to share the same namespace, it is required to make each directory of the common path a namespace package, i.e. google/ and cloud/. This should be the only use case for creating namespace packages, otherwise, there is no need for it.

It's crucial that there are no __init__py files in the google and google/cloud directories so that both directories can be interpreted as namespace packages. In Python 3.3+ any directory on the sys.path with a name that matches the package name being looked for will be recognized as contributing modules and subpackages to that package. As a result, when you import both from google_pubsub and google_storage, the Python interpreter will be able to find them.

This is different from regular packages which are self-contained meaning all parts live in the same directory hierarchy. When importing a package and the Python interpreter encounters a subdirectory on the sys.path with an __init__.py file, then it will create a single directory package containing only modules from that directory, rather than finding all appropriately named subdirectories outside that directory. This is perfectly fine for packages that don't want to share a namespace. I highly recommend taking a look at Traps for the Unwary in Python’s Import System to get a better understanding of how Python importing behaves with regular and namespace package and what __init__.py traps to watch out for.

Summary

• Only skip __init__.py files if you want to create namespace packages. Only create namespace packages if you have different libraries that reside in different locations and you want them each to contribute a subpackage to the parent package, i.e. the namespace package.
• Keep on adding empty __init__py to your directories because 99% of the time you just want to create regular packages. Also, Python tools out there such as mypy and pytest require empty __init__.py files to interpret the code structure accordingly. This can lead to weird errors if not done with care.

Resources

My answer only touches the surface of how regular packages and namespace packages work so take a look at the following resources for further information:

• PEP 420 -- Implicit Namespace Packages
• The import system - Regular packages
• The import system - Namespace packages
• Traps for the Unwary in Python’s Import System

jQuery plugin as a shorthand to directly get the whole element HTML:

jQuery.fn.outerHTML = function () {
    return jQuery('<div />').append(this.eq(0).clone()).html();
};

And use it like this: $(".element").outerHTML();

Insert into TBL (Name, UserName, Password) Output Inserted.IdentityColumnName
 Values ('example', 'example', 'example')

Preferred string type in C++ is string, defined in namespace std, in header <string> and you can initialize it like this for example:

#include <string>

int main()
{
   std::string str1("Some text");
   std::string str2 = "Some text";
}
