If you can use a C++ compiler to build the object file that you want to contain your version string, then we can do exactly what you want! The only magic here is that C++ allows you to use expressions to statically initialize an array, while C doesn't. The expressions need to be fully computable at compile time, but these expressions are, so it's no problem.

We build up the version string one byte at a time, and get exactly what we want.

This isn't exactly the format you asked for, but I still don't fully understand how you want days and hours mapped to an integer. I think it's pretty clear how to make this produce any desired string.

You could do:

brew reinstall php55-imagick

Where php55 is your PHP version.

Combining the input from everyone else (use not, no parens, use os.mkdir) you'd get...

special_path_for_john = "/usr/share/sounds/blues"
if not os.path.exists(special_path_for_john):
    os.mkdir(special_path_for_john)

This should technically be achievable using window.location.reload():

HTML:

<button (click)="refresh()">Refresh</button>

TS:

refresh(): void {
    window.location.reload();
}

Update:

Here is a basic StackBlitz example showing the refresh in action. Notice the URL on "/hello" path is retained when window.location.reload() is executed.

for converting dd/mm/yyyy to mm/dd/yyyy

=DATE(RIGHT(a1,4),MID(a1,4,2),LEFT(a1,2))

CSS

select.inpSelect {
  //Remove original arrows
  -webkit-appearance: none; 
  //Use png at assets/selectArrow.png for the arrow on the right
  //Set the background color to a BadAss Green color 
  background: url(assets/selectArrow.png) no-repeat right #BADA55;
}

You need to delete your old db folder and recreate new one. It will resolve your issue.

$order = new WC_Order( $post_id ); 

If you

echo $order->id;

then you'll be returned the id of the post from which the order is made. As you've already got that, it's probably not what you want.

echo $order->get_order_number();

will return the id of the order (with a # in front of it). To get rid of the #,

echo trim( str_replace( '#', '', $order->get_order_number() ) );

as per the accepted answer.

I wrote this answer back in '09 when Android was relatively new, and there were many not well established areas in Android development. I have added a long addendum at the bottom of this post, addressing some criticism, and detailing a philosophical disagreement I have with the use of Singletons rather than subclassing Application. Read it at your own risk.

ORIGINAL ANSWER:

The more general problem you are encountering is how to save state across several Activities and all parts of your application. A static variable (for instance, a singleton) is a common Java way of achieving this. I have found however, that a more elegant way in Android is to associate your state with the Application context.

As you know, each Activity is also a Context, which is information about its execution environment in the broadest sense. Your application also has a context, and Android guarantees that it will exist as a single instance across your application.

The way to do this is to create your own subclass of android.app.Application, and then specify that class in the application tag in your manifest. Now Android will automatically create an instance of that class and make it available for your entire application. You can access it from any context using the Context.getApplicationContext() method (Activity also provides a method getApplication() which has the exact same effect). Following is an extremely simplified example, with caveats to follow:

class MyApp extends Application {

  private String myState;

  public String getState(){
    return myState;
  }
  public void setState(String s){
    myState = s;
  }
}

class Blah extends Activity {

  @Override
  public void onCreate(Bundle b){
    ...
    MyApp appState = ((MyApp)getApplicationContext());
    String state = appState.getState();
    ...
  }
}

This has essentially the same effect as using a static variable or singleton, but integrates quite well into the existing Android framework. Note that this will not work across processes (should your app be one of the rare ones that has multiple processes).

Something to note from the example above; suppose we had instead done something like:

class MyApp extends Application {

  private String myState = /* complicated and slow initialization */;

  public String getState(){
    return myState;
  }
}

Now this slow initialization (such as hitting disk, hitting network, anything blocking, etc) will be performed every time Application is instantiated! You may think, well, this is only once for the process and I'll have to pay the cost anyways, right? For instance, as Dianne Hackborn mentions below, it is entirely possible for your process to be instantiated -just- to handle a background broadcast event. If your broadcast processing has no need for this state you have potentially just done a whole series of complicated and slow operations for nothing. Lazy instantiation is the name of the game here. The following is a slightly more complicated way of using Application which makes more sense for anything but the simplest of uses:

class MyApp extends Application {

  private MyStateManager myStateManager = new MyStateManager();

  public MyStateManager getStateManager(){
    return myStateManager ;
  }
}

class MyStateManager {

  MyStateManager() {
    /* this should be fast */
  }

  String getState() {
    /* if necessary, perform blocking calls here */
    /* make sure to deal with any multithreading/synchronicity issues */

    ...

    return state;
  }
}

class Blah extends Activity {

  @Override
  public void onCreate(Bundle b){
    ...
    MyStateManager stateManager = ((MyApp)getApplicationContext()).getStateManager();
    String state = stateManager.getState();
    ...
  }
}

While I prefer Application subclassing to using singletons here as the more elegant solution, I would rather developers use singletons if really necessary over not thinking at all through the performance and multithreading implications of associating state with the Application subclass.

NOTE 1: Also as anticafe commented, in order to correctly tie your Application override to your application a tag is necessary in the manifest file. Again, see the Android docs for more info. An example:

<application
     android:name="my.application.MyApp" 
     android:icon="..."
     android:label="...">
</application>

NOTE 2: user608578 asks below how this works with managing native object lifecycles. I am not up to speed on using native code with Android in the slightest, and I am not qualified to answer how that would interact with my solution. If someone does have an answer to this, I am willing to credit them and put the information in this post for maximum visibility.

ADDENDUM:

As some people have noted, this is not a solution for persistent state, something I perhaps should have emphasized more in the original answer. I.e. this is not meant to be a solution for saving user or other information that is meant to be persisted across application lifetimes. Thus, I consider most criticism below related to Applications being killed at any time, etc..., moot, as anything that ever needed to be persisted to disk should not be stored through an Application subclass. It is meant to be a solution for storing temporary, easily re-creatable application state (whether a user is logged in for example) and components which are single instance (application network manager for example) (NOT singleton!) in nature.

Dayerman has been kind enough to point out an interesting conversation with Reto Meier and Dianne Hackborn in which use of Application subclasses is discouraged in favor of Singleton patterns. Somatik also pointed out something of this nature earlier, although I didn't see it at the time. Because of Reto and Dianne's roles in maintaining the Android platform, I cannot in good faith recommend ignoring their advice. What they say, goes. I do wish to disagree with the opinions, expressed with regards to preferring Singleton over Application subclasses. In my disagreement I will be making use of concepts best explained in this StackExchange explanation of the Singleton design pattern, so that I do not have to define terms in this answer. I highly encourage skimming the link before continuing. Point by point:

Dianne states, "There is no reason to subclass from Application. It is no different than making a singleton..." This first claim is incorrect. There are two main reasons for this. 1) The Application class provides a better lifetime guarantee for an application developer; it is guaranteed to have the lifetime of the application. A singleton is not EXPLICITLY tied to the lifetime of the application (although it is effectively). This may be a non-issue for your average application developer, but I would argue this is exactly the type of contract the Android API should be offering, and it provides much more flexibility to the Android system as well, by minimizing the lifetime of associated data. 2) The Application class provides the application developer with a single instance holder for state, which is very different from a Singleton holder of state. For a list of the differences, see the Singleton explanation link above.

Dianne continues, "...just likely to be something you regret in the future as you find your Application object becoming this big tangled mess of what should be independent application logic." This is certainly not incorrect, but this is not a reason for choosing Singleton over Application subclass. None of Diane's arguments provide a reason that using a Singleton is better than an Application subclass, all she attempts to establish is that using a Singleton is no worse than an Application subclass, which I believe is false.

She continues, "And this leads more naturally to how you should be managing these things -- initializing them on demand." This ignores the fact that there is no reason you cannot initialize on demand using an Application subclass as well. Again there is no difference.

Dianne ends with "The framework itself has tons and tons of singletons for all the little shared data it maintains for the app, such as caches of loaded resources, pools of objects, etc. It works great." I am not arguing that using Singletons cannot work fine or are not a legitimate alternative. I am arguing that Singletons do not provide as strong a contract with the Android system as using an Application subclass, and further that using Singletons generally points to inflexible design, which is not easily modified, and leads to many problems down the road. IMHO, the strong contract the Android API offers to developer applications is one of the most appealing and pleasing aspects of programming with Android, and helped lead to early developer adoption which drove the Android platform to the success it has today. Suggesting using Singletons is implicitly moving away from a strong API contract, and in my opinion, weakens the Android framework.

Dianne has commented below as well, mentioning an additional downside to using Application subclasses, they may encourage or make it easier to write less performance code. This is very true, and I have edited this answer to emphasize the importance of considering perf here, and taking the correct approach if you're using Application subclassing. As Dianne states, it is important to remember that your Application class will be instantiated every time your process is loaded (could be multiple times at once if your application runs in multiple processes!) even if the process is only being loaded for a background broadcast event. It is therefore important to use the Application class more as a repository for pointers to shared components of your application rather than as a place to do any processing!

I leave you with the following list of downsides to Singletons, as stolen from the earlier StackExchange link:

• Inability to use abstract or interface classes;
• Inability to subclass;
• High coupling across the application (difficult to modify);
• Difficult to test (can't fake/mock in unit tests);
• Difficult to parallelize in the case of mutable state (requires extensive locking);

and add my own:

• Unclear and unmanageable lifetime contract unsuited for Android (or most other) development;

You may use this -

(data_type)log10(variable_name)+1

ex:

len = (int)log10(number)+1;

The :query_string_normalizer option is also available, which will override the default normalizer HashConversions.to_params(query)

query_string_normalizer: ->(query){query.to_json}

I'd like to add another vote for the StringFormat object. You can use this simply to specify "center, center" and the text will be drawn centrally in the rectangle or points provided:

StringFormat format = new StringFormat();
format.LineAlignment = StringAlignment.Center;
format.Alignment = StringAlignment.Center;

However there is one issue with this in CF. If you use Center for both values then it turns TextWrapping off. No idea why this happens, it appears to be a bug with the CF.

Might be a little late with the answer but you need to supply the MIME type attribute in the video tag: type="application/x-mpegURL". The video tag I use for a 16:9 stream looks like this.

<video width="352" height="198" controls>
    <source src="playlist.m3u8" type="application/x-mpegURL">
</video>

we can convert byte[] array into input stream by using ByteArrayInputStream

String str = "Welcome to awesome Java World";
    byte[] content = str.getBytes();
    int size = content.length;
    InputStream is = null;
    byte[] b = new byte[size];
    is = new ByteArrayInputStream(content);

For full example please check here http://www.onlinecodegeek.com/2015/09/how-to-convert-byte-into-inputstream.html

Just do npm update and then npm install gulp-sass --save-dev in your root folder, and then when you run you shouldn't have any issues.

If your data is positively skewed, the best way to normalize is to use the log transformation:

df = np.log10(df)

I had the same problem before. My problem was the Entity relationship I was trying to establish by using a "List". I knew it was the cause because the program ran fine without the list variable. In your case, I think the problem is:

private List<Question> _questions;

I am assuming you already have a class named Question. So, try having:

@OneToMany
private Question _questions;

But the thing is, in your method, you are going to handle it so it return a list. I used Spring Data JPA with CrudRepository. So, if you decide to use it, yours may look like this:

public List<Question> findById( Long _id );

There are more changes you will have to do, but these are pretty easy and straightforward. Refer to this Java Brains video to have a better grasp and see what else needs to be modified.

From the Mozilla Developer Network:

There is no way to stop or break a forEach() loop other than by throwing an exception. If you need such behavior, the forEach() method is the wrong tool.

Early termination may be accomplished with:

• A simple loop
• A for...of loop
• Array.prototype.every()
• Array.prototype.some()
• Array.prototype.find()
• Array.prototype.findIndex()

The other Array methods: every(), some(), find(), and findIndex() test the array elements with a predicate returning a truthy value to determine if further iteration is required.

The method is implemented in "native" code. That is, code that does not run in the JVM. It's typically written in C or C++.

Native methods are usually used to interface with system calls or libraries written in other programming languages.

Bear in mind that 0 is a special case of parameter numbers inside a batch file, where 0 means this file as given on the command line.

So if the file is myfile.bat, you could call it in several ways as follows, each of which would give you a different output from the %0 or %~0 usage:

myfile

myfile.bat

mydir\myfile.bat

c:\mydir\myfile.bat

"c:\mydir\myfile.bat"

All of the above are legal calls if you call it from the correct relative place to the directory in which it exists. %~0 strips the quotes from the last example, whereas %0 does not.

Because these all give different results, %0 and %~0 are very unlikely to be what you actually want to use.

Here's a batch file to illustrate:

@echo Full path and filename: %~f0
@echo Drive: %~d0
@echo Path: %~p0
@echo Drive and path: %~dp0
@echo Filename without extension: %~n0
@echo Filename with    extension: %~nx0
@echo Extension: %~x0
@echo Filename as given on command line: %0
@echo Filename as given on command line minus quotes: %~0
@REM Build from parts
@SETLOCAL
@SET drv=%~d0
@SET pth=%~p0
@SET fpath=%~dp0
@SET fname=%~n0
@SET ext=%~x0
@echo Simply Constructed name: %fpath%%fname%%ext%
@echo Fully  Constructed name: %drv%%pth%%fname%%ext%
@ENDLOCAL
pause

The guys have given the simple solution, which will do be you should have a look at the help - it's good, looks like a lot in one go but it's actually quick to read:

get-help about_Remote_Troubleshooting | more

From the stack trace it's clear that, the ThreadPoolExecutor > Worker thread started and it's waiting for the task to be available on the BlockingQueue(DelayedWorkQueue) to pick the task and execute.So this thread will be in WAIT status only as long as get a SIGNAL from the publisher thread.

One possible issue is that your new class has a different Target or different Targets from the other one.

For example, it might have a testing target while the other one doesn't. For this specific case, you have to include all of your classes in the testing target or none of them.

None of the above worked for me. But what actually worked was deleting all *.snap files from my workspace. This also preserves almost all settings including imported projects. Make sure to back up the workspace before trying it though!!!

Use "&" instead of "&".

I think, the best and easy way for you, to put value inside quotes is:

JSON.stringify(variable or value)

The best way is to interact with the axes object directly

import numpy as np
import matplotlib.pyplot as plt
x = np.arange(0, 10, 0.1)
y1 = 0.05 * x**2
y2 = -1 *y1

fig, ax1 = plt.subplots()

ax2 = ax1.twinx()
ax1.plot(x, y1, 'g-')
ax2.plot(x, y2, 'b-')

ax1.set_xlabel('X data')
ax1.set_ylabel('Y1 data', color='g')
ax2.set_ylabel('Y2 data', color='b')

plt.show()

Eloquent uses the query builder internally, so you can do:

$users = User::orderBy('name', 'desc')
                ->groupBy('count')
                ->having('count', '>', 100)
                ->get();

Basically an XSD file defines how the XML file is going to look like. It's a Schema file which defines the structure of the XML file. So it specifies what the possible fields are and what size they are going to be.

An XML file is an instance of XSD as it uses the rules defined in the XSD.

I use the following function. It is not the most memory efficient but it is very simple to understand, supports multiple compare methods, is only 4 lines, is fast, mostly works in VBA too, will find not just individual characters but any search string (I often search for VbCrLf (s)).

Only thing missing is the ability to start search from a different "Start"

    Function inStC(myInput As String, Search As String, Optional myCompareMethod As Long = CompareMethod.Text) As Long
        If InStr(1, myInput, Search, myCompareMethod) = 0 Then Return 0
        Return UBound(Split(myInput, Search,, myCompareMethod))
    End Function

One thing I like is that it is compact to use example.

str="the little red hen"
count=inStC(str,"e") 'count should equal 4
count=inStC(str,"t") 'count should equal 3

While I am here, I would like to shill my inStB function, which, instead of returning a count of a string, it will simply return a boolean if the search string is present. I need this function often and this makes my code cleaner.

Function inStB(myInput As String, Search As String, Optional Start As Long = 1, Optional myCompareMethod As Long = CompareMethod.Text) As Boolean
    If InStr(Start, myInput, Search, myCompareMethod) > 0 Then Return True
    Return False
End Function

If you've exported the environment variable:

export demoPath=/usr/local/demo

you can simply refer to it by name in the makefile (make imports all the environment variables you have set):

DEMOPATH = ${demoPath}    # Or $(demoPath) if you prefer.

If you've not exported the environment variable, it is not accessible until you do export it, or unless you pass it explicitly on the command line:

make DEMOPATH="${demoPath}" …

If you are using a C shell derivative, substitute setenv demoPath /usr/local/demo for the export command.

In Oracle 12c you can use the function STANDARD_HASH. It does not require any additional privileges.

select standard_hash('foo', 'MD5') from dual;

The dbms_obfuscation_toolkit is deprecated (see Note here). You can use DBMS_CRYPTO directly:

select rawtohex(
    DBMS_CRYPTO.Hash (
        UTL_I18N.STRING_TO_RAW ('foo', 'AL32UTF8'),
        2)
    ) from dual;

Output:

ACBD18DB4CC2F85CEDEF654FCCC4A4D8

Add a lower function call if needed. More on DBMS_CRYPTO.

public static Dictionary<string, IEnumerable<int>> GetWordsPositions(this string input, string[] Susbtrings)
{
    Dictionary<string, IEnumerable<int>> WordsPositions = new Dictionary<string, IEnumerable<int>>();
    IEnumerable<int> IndexOfAll = null;
    foreach (string st in Susbtrings)
    {
        IndexOfAll = Regex.Matches(input, st).Cast<Match>().Select(m => m.Index);
        WordsPositions.Add(st, IndexOfAll);

    }
    return WordsPositions;
}

How about with jQuery? A simple...

$(window).load(function() {      //Do the code in the {}s when the window has loaded 
  $("#loader").fadeOut("fast");  //Fade out the #loader div
});

And the HTML...

<div id="loader"></div>

And CSS...

#loader {
      width: 100%;
      height: 100%;
      background-color: white;
      margin: 0;
}

Then in your loader div you would put the GIF, and any text you wanted, and it will fade out once the page has loaded.

On CentOS Linux release 7.5.1804, we were able to make this work by editing /etc/selinux/config and changing the setting of SELINUX like so:

SELINUX=disabled

You can cast the the json as follows:

Given your class:

export class Employee{
    firstname: string= '';
}

and the json:

let jsonObj = {
    "firstname": "Hesham"
};

You can cast it as follows:

let e: Employee = jsonObj as Employee;

And the output of console.log(e); is:

{ firstname: 'Hesham' }

Interesting, I didn't have any references to stdole in my project, but I had a user still receiving the error. I had to add the reference, then change the setting to include. Hopefully that will work.

You CAN use UTF-8 in the POST request, all you need is to specify the charset in your request.

You should use this request:

curl -X POST -H "Content-Type: application/x-www-form-urlencoded; charset=utf-8" --data-ascii "content=derinhält&date=asdf" http://myserverurl.com/api/v1/somemethod

You probably need to wrap the UNION in a sub-SELECT and apply the WHERE clause afterward:

SELECT * FROM (
    SELECT * FROM Table1 WHERE Field1 = Value1
    UNION
    SELECT * FROM Table2 WHERE Field1 = Value2
) AS t WHERE Field2 = Value3

Basically, the UNION is looking for two complete SELECT statements to combine, and the WHERE clause is part of the SELECT statement.

It may make more sense to apply the outer WHERE clause to both of the inner queries. You'll probably want to benchmark the performance of both approaches and see which works better for you.

I will be answering this in general terms, and very thankful to the above contributers.
I am using MySQL on MySQL Workbench. I had a similar issue trying to concatenate a char and an int together using the GROUP_CONCAT method. In summary, what has worked for me is this:

let's say your char is 'c' and int is 'i', so, the query becomes:
...GROUP_CONCAT(CONCAT(c,' ', CAST(i AS CHAR))...

Personally, I wouldn't use the LIKE string comparison on the ID field or any other numeric field. It doesn't make sense for a search for ID# "216" to return 16216, 21651, 3216087, 5321668..., and so on and so forth; likewise with salary.

Also, if you want to use prepared statements to prevent SQL injections, you would use a query string like:

SELECT * FROM job WHERE `position` LIKE CONCAT('%', ? ,'%') OR ...

You can add this piece of code to the top of your batch file:

@Echo off
SET LOGFILE=MyLogFile.log
call :Logit >> %LOGFILE% 
exit /b 0

:Logit
:: The rest of your code
:: ....

It basically redirects the output of the :Logit method to the LOGFILE. The exit command is to ensure the batch exits after executing :Logit.

When you are going for strict XHTML compliance, you need the CDATA so less than and ampersands are not flagged as invalid characters.

this is what it worked for me:

select * from table
where column
BETWEEN STR_TO_DATE('29/01/15', '%d/%m/%Y')
 AND STR_TO_DATE('07/10/15', '%d/%m/%Y')

Please, note that I had to change STR_TO_DATE(column, '%d/%m/%Y') from previous solutions, as it was taking ages to load

#!/bin/bash
filename=program.c
name=$(basename "$filename" .c)
echo "$name"

outputs:

program

The main issue with your example that you can't implicitly convert Task<T> return types to the base T type. You need to use the Task.Result property. Note that Task.Result will block async code, and should be used carefully.

Try this instead:

public List<int> TestGetMethod()  
{  
    return GetIdList().Result;  
}

This is my working example of our simple Vue component.

<template functional>
    <div v-html="require('!!html-loader!./../svg/logo.svg')"></div>
</template>

It will redirect your store page to your contact page

    <IfModule mod_rewrite.c>
    RewriteEngine On 
    RewriteBase /
    Redirect 301 /storepage /contactpage
    </IfModule>

This sounds like NTFS permissions. It usually means your SQL Server service account has read only access to the file (note that SQL Server uses the same service account to access database files regardless of how you log in). Are you sure you didn't change the folder permissions in between logging in as yourself and logging in as sa? If you detach and try again, does it still have the same problem?

I've have the same problem like this, but using my own server. Maybe APACHE is allowing only limited connection to the same server. I'm increasing the max_connection and KeepAlive setting. So far so good.

Another option would be to use a symbolic link. ie:

ln -s ~/Files/Scripts/Main ~/myFold

After that you can perform operations to ~/myFold, such as:

cp some_file.txt ~/myFold

which will put the file in ~/Files/Scripts/Main. You can remove the symbolic link at any time with rm ~/myFold, which will keep the original directory.

The element has both an attribute and a property named checked. The property determines the current state.

The attribute is a string, and the property is a boolean. When the element is created from the HTML code, the attribute is set from the markup, and the property is set depending on the value of the attribute.

If there is no value for the attribute in the markup, the attribute becomes null, but the property is always either true or false, so it becomes false.

When you set the property, you should use a boolean value:

document.getElementById('myRadio').checked = true;

If you set the attribute, you use a string:

document.getElementById('myRadio').setAttribute('checked', 'checked');

Note that setting the attribute also changes the property, but setting the property doesn't change the attribute.

Note also that whatever value you set the attribute to, the property becomes true. Even if you use an empty string or null, setting the attribute means that it's checked. Use removeAttribute to uncheck the element using the attribute:

document.getElementById('myRadio').removeAttribute('checked');

Also use NVL2 as below if you want to return other value from the field_to_check:

NVL2( field_to_check, value_if_NOT_null, value_if_null )

Usage: ORACLE/PLSQL: NVL2 FUNCTION

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    std::string ciphertext;
    std::string decryptedtext;

    //
    // Dump Plain Text
    //
    std::cout << "Plain Text (" << plaintext.size() << " bytes)" << std::endl;
    std::cout << plaintext;
    std::cout << std::endl << std::endl;

    //
    // Create Cipher Text
    //
    CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    //
    // Decrypt
    //
    CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

    //
    // Dump Decrypted Text
    //
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

    return 0;
}

For installation details :

• How do I install Crypto++ in Visual Studio 2010 Windows 7?
• *nix environment
• For Ubuntu I did:

sudo apt-get install libcrypto++-dev libcrypto++-doc libcrypto++-utils

This works for me:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- NOTE: order is important (the first matching state(s) is what is rendered) -->
    <item 
        android:state_selected="true" 
        android:drawable="@drawable/info_icon_solid_with_shadow" />
    <item 
        android:drawable="@drawable/info_icon_outline_with_shadow" />
 </selector>

And then in java:

//assign the image in code (or you can do this in your layout xml with the src attribute)
imageButton.setImageDrawable(getBaseContext().getResources().getDrawable(R.drawable....));

//set the click listener
imageButton.setOnClickListener(new OnClickListener() {

    public void onClick(View button) {
        //Set the button's appearance
        button.setSelected(!button.isSelected());

        if (button.isSelected()) {
            //Handle selected state change
        } else {
            //Handle de-select state change
        }

    }

});

For smooth transition you can also mention animation time:

<selector xmlns:android="http://schemas.android.com/apk/res/android" android:exitFadeDuration="@android:integer/config_mediumAnimTime">

Same question already answered here: How to list/download the recursive dependencies of a debian package?

try:

My suggestion would be to get the book Programming From Ground Up:

http://nongnu.askapache.com/pgubook/ProgrammingGroundUp-1-0-booksize.pdf

That is a very good starting point for getting into assembler programming under linux and it explains a lot of the basics you need to understand to get started.

This is deliberate. The contents of the "file" may not be available as a file. Remember you are dealing with classes and resources that may be part of a JAR file or other kind of resource. The classloader does not have to provide a file handle to the resource, for example the jar file may not have been expanded into individual files in the file system.

Anything you can do by getting a java.io.File could be done by copying the stream out into a temporary file and doing the same, if a java.io.File is absolutely necessary.

Utilizing/Copying Darin Dimitrov's great response, this is how to access a custom attribute on a property and not a class:

The decorated property [of class Foo]:

[MyCustomAttribute(SomeProperty = "This is a custom property")]
public string MyProperty { get; set; }

Fetching it:

PropertyInfo propertyInfo = typeof(Foo).GetProperty(propertyToCheck);
object[] attribute = propertyInfo.GetCustomAttributes(typeof(MyCustomAttribute), true);
if (attribute.Length > 0)
{
    MyCustomAttribute myAttribute = (MyCustomAttribute)attribute[0];
    string propertyValue = myAttribute.SomeProperty;
}

You can throw this in a loop and use reflection to access this custom attribute on each property of class Foo, as well:

foreach (PropertyInfo propertyInfo in Foo.GetType().GetProperties())
{
    string propertyName = propertyInfo.Name;

    object[] attribute = propertyInfo.GetCustomAttributes(typeof(MyCustomAttribute), true);
    // Just in case you have a property without this annotation
    if (attribute.Length > 0)
    {
        MyCustomAttribute myAttribute = (MyCustomAttribute)attribute[0];
        string propertyValue = myAttribute.SomeProperty;
        // TODO: whatever you need with this propertyValue
    }
}

Major thanks to you, Darin!!

THIS ANSWER IS FOR ANIMATIONS ONLY


If you wanna implement the AND logic, you should use MultiTrigger, here is an example:

Suppose we want to do some actions if the property Text="" (empty string) AND IsKeyboardFocused="False", then your code should look like the following:

<MultiTrigger>
    <MultiTrigger.Conditions>
        <Condition Property="Text" Value="" />
        <Condition Property="IsKeyboardFocused" Value="False" />
    </MultiTrigger.Conditions>
        <MultiTrigger.EnterActions>
            <!-- Your actions here -->
        </MultiTrigger.EnterActions>
</MultiTrigger>

If you wanna implement the OR logic, there are couple of ways, and it depends on what you try to do:

The first option is to use multiple Triggers.
So, suppose you wanna do something if either Text="" OR IsKeyboardFocused="False",
then your code should look something like this:

<Trigger Property="IsEnabled" Value="false">
    <Setter Property="Opacity" TargetName="border" Value="0.56"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
    <Setter Property="BorderBrush" TargetName="border" 
            Value="{StaticResource TextBox.MouseOver.Border}"/>
</Trigger>

But the problem in this is what will I do if i wanna do something if either Text ISN'T null OR IsKeyboard="True"? This can be achieved by the second approach:
Recall De Morgan's rule, that says !(!x && !y) = x || y.
So we'll use it to solve the previous problem, by writing a multi trigger that it's triggered when Text="" and IsKeyboard="True", and we'll do our actions in EXIT ACTIONS, like this:

<MultiTrigger>
    <MultiTrigger.Conditions>
        <Condition Property="Text" Value="" />
        <Condition Property="IsKeyboardFocused" Value="False" />
    </MultiTrigger.Conditions>
    <MultiTrigger.ExitActions>
        <!-- Do something here -->
    </MultiTrigger.ExitActions>
</MultiTrigger>

You're mixing notations. It should be:

<img src="folder/file.jpg" width="200" height="200">

(note, no px). Or:

<img src="folder/file.jpg" style="width: 200px; height: 200px;">

(using the style attribute) The style attribute could be replaced with the following CSS:

#mydiv img {
    width: 200px;
    height: 200px;
}

or

#mydiv img {
    width: 100%;
    height: 100%;
}

you have to first download the get-pip.py and then run the command :

python get-pip.py

• Open the PDF in MacOS´ Preview App
• Chose File menu –> Export as PDF
• In the export dialog klick the Details button an select your page size
• Click save

All pages of the resulting document will be scaled to that size. The resulting file size is nearly identical to the original PDF, so I conclude, that image resolutions/compressions are not changed.

Hints:

1. I am not sure whether the "Export as PDF" menu item is available by default or only if Adobe Acrobat is installed.

2. My first trial was to use Preview App and print (!) into a new PDF, but this leads to additional margins around the page content.

I have made this like that.

    Random random = new Random();
    ArrayList<Integer> arrayList = new ArrayList<Integer>();

    while (arrayList.size() < 6) { // how many numbers u need - it will 6
        int a = random.nextInt(49)+1; // this will give numbers between 1 and 50.

        if (!arrayList.contains(a)) {
            arrayList.add(a);
        }
    }

You can call the mklink provided by cmd, from PowerShell to make symbolic links:

cmd /c mklink c:\path\to\symlink c:\target\file

You must pass /d to mklink if the target is a directory.

cmd /c mklink /d c:\path\to\symlink c:\target\directory

For hard links, I suggest something like Sysinternals Junction.

If you want to call an action from your JavaScript, one way is to embed your JavaScript code, inside your view (.cshtml file for example), and then, use Razor, to create a URL of that action:

$(function(){
    $('#sampleDiv').click(function(){
        /*
         While this code is JavaScript, but because it's embedded inside
         a cshtml file, we can use Razor, and create the URL of the action

         Don't forget to add '' around the url because it has to become a     
         valid string in the final webpage
        */

        var url = '@Url.Action("ActionName", "Controller")';
    });
});

I had an issue with the proposed solutions, using lookup does not always return the expected value.

This is due to DNS caching, the value of the call is cached and intead of doing a proper call on the next try it gives back the cached value. Of course this is an issue here as it means if you lose connectivity and call lookup it could still return the cached value as if you had internet, and conversely, if you reconnect your internet after lookup returned null it will still return null for the duration of the cache, which can be a few minutes, even if you do have internet now.

TL;DR: lookup returning something does not necessarily mean you have internet, and it not returning anything does not necessarily mean you don't have internet. It is not reliable.

I implemented the following solution by taking inspiration from the data_connection_checker plugin:

 /// If any of the pings returns true then you have internet (for sure). If none do, you probably don't.
  Future<bool> _checkInternetAccess() {
    /// We use a mix of IPV4 and IPV6 here in case some networks only accept one of the types.
    /// Only tested with an IPV4 only network so far (I don't have access to an IPV6 network).
    final List<InternetAddress> dnss = [
      InternetAddress('8.8.8.8', type: InternetAddressType.IPv4), // Google
      InternetAddress('2001:4860:4860::8888', type: InternetAddressType.IPv6), // Google
      InternetAddress('1.1.1.1', type: InternetAddressType.IPv4), // CloudFlare
      InternetAddress('2606:4700:4700::1111', type: InternetAddressType.IPv6), // CloudFlare
      InternetAddress('208.67.222.222', type: InternetAddressType.IPv4), // OpenDNS
      InternetAddress('2620:0:ccc::2', type: InternetAddressType.IPv6), // OpenDNS
      InternetAddress('180.76.76.76', type: InternetAddressType.IPv4), // Baidu
      InternetAddress('2400:da00::6666', type: InternetAddressType.IPv6), // Baidu
    ];

    final Completer<bool> completer = Completer<bool>();

    int callsReturned = 0;
    void onCallReturned(bool isAlive) {
      if (completer.isCompleted) return;

      if (isAlive) {
        completer.complete(true);
      } else {
        callsReturned++;
        if (callsReturned >= dnss.length) {
          completer.complete(false);
        }
      }
    }

    dnss.forEach((dns) => _pingDns(dns).then(onCallReturned));

    return completer.future;
  }

  Future<bool> _pingDns(InternetAddress dnsAddress) async {
    const int dnsPort = 53;
    const Duration timeout = Duration(seconds: 3);

    Socket socket;
    try {
      socket = await Socket.connect(dnsAddress, dnsPort, timeout: timeout);
      socket?.destroy();
      return true;
    } on SocketException {
      socket?.destroy();
    }
    return false;
  }

The call to _checkInternetAccess takes at most a duration of timeout to complete (3 seconds here), and if we can reach any of the DNS it will complete as soon as the first one is reached, without waiting for the others (as reaching one is enough to know you have internet). All the calls to _pingDns are done in parallel.

It seems to work well on an IPV4 network, and when I can't test it on an IPV6 network (I don't have access to one) I think it should still work. It also works on release mode builds, but I yet have to submit my app to Apple to see if they find any issue with this solution.

It should also work in most countries (including China), if it does not work in one you can add a DNS to the list that is accessible from your target country.

Aangular 2 final has updated APIs. They have added many methods for this.

To update the form control from controller do this:

this.form.controls['dept'].setValue(selected.id);

this.form.controls['dept'].patchValue(selected.id);

No need to reset the errors

You could include the same project in more than one solution, but you're guaranteed to run into problems sometime down the road (relative paths can become invalid when you move directories around for example)

After years of struggling with this, I finally came up with a workable solution, but it requires you to use Subversion for source control (which is not a bad thing)

At the directory level of your solution, add a svn:externals property pointing to the projects you want to include in your solution. Subversion will pull the project from the repository and store it in a subfolder of your solution file. Your solution file can simply use relative paths to refer to your project.

If I find some more time, I'll explain this in detail.

Sometimes changing the date format doesn't work properly, especially in Laravel. So in that case, it's better to use:

$date1 = strtr($_REQUEST['date'], '/', '-');
echo date('Y-m-d', strtotime($date1));

Then you can avoid error like "1970-01-01"!

It is difficult to say how the memory allocation will affect your speed. It depends on the garbage collection algorithm the JVM is using. For example if your garbage collector needs to pause to do a full collection, then if you have 10 more memory than you really need then the collector will have 10 more garbage to clean up.

If you are using java 6 you can use the jconsole (in the bin directory of the jdk) to attach to your process and watch how the collector is behaving. In general the collectors are very smart and you won't need to do any tuning, but if you have a need there are numerous options you have use to further tune the collection process.

If you're looking to get promise in resource call, you should use

Regions.query().$q.then(function(){ .... })

Update : the promise syntax is changed in current versions which reads

Regions.query().$promise.then(function(){ ..... })

Those who have downvoted don't know what it was and who first added this promise to resource object. I used this feature in late 2012 - yes 2012.

In java, there are two types of parameters, implicit parameters and explicit parameters. Explicit parameters are the arguments passed into a method. The implicit parameter of a method is the instance that the method is called from. Arguments are simply one of the two types of parameters.

@AlexeiLevenkov pointed me at another "easiest way" namely the extension method. It takes just a little coding, then provides the absolute easiest way to read/write, plus it offers the flexibility to create variations according to your personal needs. Here is a complete example:

This defines the extension method on the string type. Note that the only thing that really matters is the function argument with extra keyword this, that makes it refer to the object that the method is attached to. The class name does not matter; the class and method must be declared static.

using System.IO;//File, Directory, Path

namespace Lib
{
    /// <summary>
    /// Handy string methods
    /// </summary>
    public static class Strings
    {
        /// <summary>
        /// Extension method to write the string Str to a file
        /// </summary>
        /// <param name="Str"></param>
        /// <param name="Filename"></param>
        public static void WriteToFile(this string Str, string Filename)
        {
            File.WriteAllText(Filename, Str);
            return;
        }

        // of course you could add other useful string methods...
    }//end class
}//end ns

This is how to use the string extension method, note that it refers automagically to the class Strings:

using Lib;//(extension) method(s) for string
namespace ConsoleApp_Sandbox
{
    class Program
    {
        static void Main(string[] args)
        {
            "Hello World!".WriteToFile(@"c:\temp\helloworld.txt");
            return;
        }

    }//end class
}//end ns

I would never have found this myself, but it works great, so I wanted to share this. Have fun!

NOT STRICTLY RELATED TO TYPESCRIPT

Just to add to all the above answers, we can also use the shorthand syntax

var result = uemail || '';

This will give you the email if uemail variable has some value and it will simply return an empty string if uemail variable is undefined.

This gives a nice syntax for handling undefined variables and also provide a way to use a default value in case the variable is undefined.

  <body ng-app="app">
  <button type="button" ng-click="showme==true ? !showme :showme;message='Cancel Quiz'"  class="btn btn-default">{{showme==true ? 'Cancel Quiz': 'Take a Quiz'}}</button>
    <div ng-show="showme" class="panel panel-primary col-sm-4" style="margin-left:250px;">
      <div class="panel-heading">Take Quiz</div>
      <div class="form-group col-sm-8 form-inline" style="margin-top: 30px;margin-bottom: 30px;">

        <button type="button" class="btn btn-default">Start Quiz</button>
      </div>
    </div>
  </body>

Button toggle and change header of button and show/hide div panel. See the Plunkr

nohup some_command &> nohup2.out &

and voila.

Older syntax for Bash version < 4:

nohup some_command > nohup2.out 2>&1 &

You probably redefined your "sum" function to be an integer data type. So it is rightly telling you that an integer is not something you can pass a range.

To fix this, restart your interpreter.

Python 2.7.3 (default, Apr 20 2012, 22:44:07) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> data1 = range(0, 1000, 3)
>>> data2 = range(0, 1000, 5)
>>> data3 = list(set(data1 + data2)) # makes new list without duplicates
>>> total = sum(data3) # calculate sum of data3 list's elements
>>> print total
233168

If you shadow the sum builtin, you can get the error you are seeing

>>> sum = 0
>>> total = sum(data3) # calculate sum of data3 list's elements
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable

Also, note that sum will work fine on the set there is no need to convert it to a list

(Updated to include @Socowi's execellent speed improvement)

With any $SHELL that supports it (dash/zsh/bash...):

find . -name "*.txt" -exec $SHELL -c '
    for i in "$@" ; do
        echo "$i"
    done

Done.

Original answer (shorter, but slower):

find . -name "*.txt" -exec $SHELL -c '
    echo "$0"
' {} \;

Use the built-in function dir().

Swift 3.1

extension UITextField

        let View = UIView(frame: Frame)
        View.backgroundColor = backgroundColor

        let imageView = UIImageView(frame: Frame)
        imageView.image = UIImage(named: imageName)

        View.addSubview(imageView)

        if Direction.Left == direction
        {
            self.leftViewMode = .always
            self.leftView = View
        }
        else
        {
            self.rightViewMode = .always
            self.rightView = View
        }
    }

}

Supported Python Versions

To cite the Zen of Python:

Readability counts.

For example, Python 3.7 introduced dataclasses and Python 3.8 introduced fstring =.

There might be other features in Python 3.7 and Python 3.8 which are more important to you. The point is that PyPy does not support Python 3.7 or Python 3.8 at the moment.

Shameless self-advertisement: Killer Features by Python version - if you want to know more things you miss by using older Python versions

Ctrl + Space

or

Ctrl + J

You can also go to menu Tools ? Options ? Environment ? Keyboard and check what is assigned to these shortcuts. The command name should be Edit.CompleteWord.

Pure HTML solution:

(No javascript needed, no css needed and no hidden inputs needed)

<form autoComplete="new-password" ... >
        <input name="myInput" type="text" autoComplete="off" id="myInput" placeholder="Search field" />
</form>

Notes:

• form does not necessarily need to be the direct parent of the input element
• input needs a name attribute

I found the following solution:

public static Double getFloatAsDouble(Float fValue) {
    return Double.valueOf(fValue.toString());
}

If you use float and double instead of Float and Double use the following:

public static double getFloatAsDouble(float value) {
    return Double.valueOf(Float.valueOf(value).toString()).doubleValue();
}

use overflow:auto it will give a scroller to your text within the div :).

In ubuntu it should be under

/home/user_name/product_name/system/log

where user_name is logged in user name and product_name could be e.g. .AndroidStudio1.5

following code works just fine for me.

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(movieurl));
startActivity(intent);

I feel the simplest way would be

 from matplotlib import pyplot;
 from pylab import genfromtxt;  
 mat0 = genfromtxt("data0.txt");
 mat1 = genfromtxt("data1.txt");
 pyplot.plot(mat0[:,0], mat0[:,1], label = "data0");
 pyplot.plot(mat1[:,0], mat1[:,1], label = "data1");
 pyplot.legend();
 pyplot.show();

1. label is the string that is displayed on the legend
2. you can plot as many series of data points as possible before show() to plot all of them on the same graph This is the simple way to plot simple graphs. For other options in genfromtxt go to this url.

string.substring(start,end)

where

start = Required. The position where to start the extraction. First character is at index 0`.

end = Optional. The position (up to, but not including) where to end the extraction. If omitted, it extracts the rest of the string.

    var string = "var1/var2/var3";

    start   = string.lastIndexOf('/');  //console.log(start); o/p:- 9
    end     = string.length;            //console.log(end);   o/p:- 14

    var string_before_last_slash = string.substring(0, start);
    console.log(string_before_last_slash);//o/p:- var1/var2

    var string_after_last_slash = string.substring(start+1, end);
    console.log(string_after_last_slash);//o/p:- var3

OR

    var string_after_last_slash = string.substring(start+1);
    console.log(string_after_last_slash);//o/p:- var3

A nice way of doing this is to use the addObserver(forName:object:queue:using:) method rather than the addObserver(_:selector:name:object:) method that is often used from Objective-C code. The advantage of the first variant is that you don't have to use the @objc attribute on your method:

    func batteryLevelChanged(notification: Notification) {
        // do something useful with this information
    }

    let observer = NotificationCenter.default.addObserver(
        forName: NSNotification.Name.UIDeviceBatteryLevelDidChange,
        object: nil, queue: nil,
        using: batteryLevelChanged)

and you can even just use a closure instead of a method if you want:

    let observer = NotificationCenter.default.addObserver(
        forName: NSNotification.Name.UIDeviceBatteryLevelDidChange,
        object: nil, queue: nil) { _ in print("") }

You can use the returned value to stop listening for the notification later:

    NotificationCenter.default.removeObserver(observer)

There used to be another advantage in using this method, which was that it doesn't require you to use selector strings which couldn't be statically checked by the compiler and so were fragile to breaking if the method is renamed, but Swift 2.2 and later include #selector expressions that fix that problem.

I think Internal and External Linkage in C++ gives a clear and concise explanation:

A translation unit refers to an implementation (.c/.cpp) file and all header (.h/.hpp) files it includes. If an object or function inside such a translation unit has internal linkage, then that specific symbol is only visible to the linker within that translation unit. If an object or function has external linkage, the linker can also see it when processing other translation units. The static keyword, when used in the global namespace, forces a symbol to have internal linkage. The extern keyword results in a symbol having external linkage.

The compiler defaults the linkage of symbols such that:

Non-const global variables have external linkage by default
Const global variables have internal linkage by default
Functions have external linkage by default

Here is a suggestion for when you don't know the number or name of the columns in the Dataframe.

val dfResults = dfSource.select(concat_ws(",",dfSource.columns.map(c => col(c)): _*))

SessionFactory vs. EntityManagerFactory

As I explained in the Hibernate User Guide, the Hibernate SessionFactory extends the JPA EntityManagerFactory, as illustrated by the following diagram:

So, the SessionFactory is also a JPA EntityManagerFactory.

Both the SessionFactory and the EntityManagerFactory contain the entity mapping metadata and allow you to create a Hibernate Session or a EntityManager.

Session vs. EntityManager

Just like the SessionFactory and EntityManagerFactory, the Hibernate Session extends the JPA EntityManager. So, all methods defined by the EntityManager are available in the Hibernate Session.

The Session and the `EntityManager translate entity state transitions into SQL statements, like SELECT, INSERT, UPDATE, and DELETE.

Hibernate vs. JPA bootstrap

When bootstrapping a JPA or Hibernate application, you have two choices:

1. You can bootstrap via the Hibernate native mechanism, and create a SessionFactory via the BootstrapServiceRegistryBuilder. If you're using Spring, the Hibernate bootstrap is done via the LocalSessionFactoryBean, as illustrated by this GitHub example.
2. Or, you can create a JPA EntityManagerFactory via the Persistence class or the EntityManagerFactoryBuilder. If you're using Spring, the JPA bootstrap is done via the LocalContainerEntityManagerFactoryBean, as illustrated by this GitHub example.

Bootstrapping via JPA is to be preferred. That's because the JPA FlushModeType.AUTO is a much better choice than the legacy FlushMode.AUTO, which breaks read-your-writes consistency for native SQL queries.

Unwrapping JPA to Hibernate

Also, if you bootstrap via JPA, and you have injected the EntityManagerFactory via the @PersistenceUnit annotation:

@PersistenceUnit
private EntityManagerFactory entityManagerFactory;

You can easily get access to the underlying Sessionfactory using the unwrap method:

SessionFactory sessionFactory = entityManagerFactory.unwrap(SessionFactory.class);

The same can be done with the JPA EntityManager. If you inject the EntityManager via the @PersistenceContext annotation:

@PersistenceContext
private EntityManager entityManager;

You can easily get access to the underlying Session using the unwrap method:

Session session = entityManager.unwrap(Session.class);

Conclusion

So, you should bootstrap via JPA, use the EntityManagerFactory and EntityManager, and only unwrap those to their associated Hibernate interfaces when you want to get access to some Hibernate-specific methods that are not available in JPA, like fetching the entity via its natural identifier.

Check Below Codes :

1. SynchronousRequest

Swift 1.2

    let urlPath: String = "YOUR_URL_HERE"
    var url: NSURL = NSURL(string: urlPath)!
    var request1: NSURLRequest = NSURLRequest(URL: url)
    var response: AutoreleasingUnsafeMutablePointer<NSURLResponse?>=nil
    var dataVal: NSData =  NSURLConnection.sendSynchronousRequest(request1, returningResponse: response, error:nil)!
    var err: NSError
    println(response)
    var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(dataVal, options: NSJSONReadingOptions.MutableContainers, error: &err) as? NSDictionary
    println("Synchronous\(jsonResult)")

Swift 2.0 +

let urlPath: String = "YOUR_URL_HERE"
    let url: NSURL = NSURL(string: urlPath)!
    let request1: NSURLRequest = NSURLRequest(URL: url)
    let response: AutoreleasingUnsafeMutablePointer<NSURLResponse?>=nil

    self.dataVal?.appendData(data)
}


func connectionDidFinishLoading(connection: NSURLConnection!)
{
    var error: NSErrorPointer=nil

I don't think there's type-safe method that can do what you want.

"hello _there_".replace(/_(.*?)_/, function(a, b){
    return '<div>' + b + '</div>';
})

Oh, or you could also:

"hello _there_".replace(/_(.*?)_/, "<div>$1</div>")

EDIT by Liran H: For six other people including myself, $1 did not work, whereas \1 did.

Just in case you actually mean 'discard changes' whenever you use 'git stash' (and don't really use git stash to stash it temporarily), in that case you can use

git checkout -- <file>

Note that git stash is just a quicker and simple alternative to branching and doing stuff.

1) Your existing web.config: you have declared rewrite map .. but have not created any rules that will use it. RewriteMap on its' own does absolutely nothing.

2) Below is how you can do it (it does not utilise rewrite maps -- rules only, which is fine for small amount of rewrites/redirects):

This rule will do SINGLE EXACT rewrite (internal redirect) /page to /page.html. URL in browser will remain unchanged.

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRewrite" stopProcessing="true">
                <match url="^page$" />
                <action type="Rewrite" url="/page.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

This rule #2 will do the same as above, but will do 301 redirect (Permanent Redirect) where URL will change in browser.

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRedirect" stopProcessing="true">
                <match url="^page$" />
                <action type="Redirect" url="/page.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

Rule #3 will attempt to execute such rewrite for ANY URL if there are such file with .html extension (i.e. for /page it will check if /page.html exists, and if it does then rewrite occurs):

<system.webServer>
    <rewrite>
        <rules>
            <rule name="DynamicRewrite" stopProcessing="true">
                <match url="(.*)" />
                <conditions>
                    <add input="{REQUEST_FILENAME}\.html" matchType="IsFile" />
                </conditions>
                <action type="Rewrite" url="/{R:1}.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

I ended up using a shell script with the following code:

#!/bin/bash

while [ 1 == 1 ]
do
    clear
    ps auxf |grep -ve "grep" |grep -E "MSG[^\ ]*" --color=auto
    sleep 5
done

Another option is to put all of the fields that you want on a single line within a single form-group.

See demo here

<form class="form-horizontal">
    <div class="form-group">
        <label for="name" class="col-xs-2 control-label">Name</label>
        <div class="col-xs-10">
            <input type="text" class="form-control col-sm-10" name="name" placeholder="name"/>
        </div>
    </div>

    <div class="form-group">
        <label for="birthday" class="col-xs-3 col-sm-2 control-label">Birthday</label>
        <div class="col-xs-3">
            <input type="text" class="form-control" placeholder="year"/>
        </div>
        <div class="col-xs-3">
            <input type="text" class="form-control" placeholder="month"/>
        </div>
        <div class="col-xs-3">
            <input type="text" class="form-control" placeholder="day"/>
        </div>    
    </div>
</form>

just for the record you can always compare using JSON.stringify

const arr = [1,2,3]; expect(JSON.stringify(arr)).toBe(JSON.stringify([1,2,3])); expect(JSON.stringify(arr)).toEqual(JSON.stringify([1,2,3]));

It's all meter of taste, this will also work for complex literal objects

There is a better way to write polar(), here it is:

def polar(x,y):
  `returns r, theta(degrees)`
  return math.hypot(x,y),math.degrees(math.atan2(y,x))

Well, if the string really ends with the pattern, you could do this:

str = str.replace(new RegExp(list[i] + '$'), 'finish');

I fixed this problem in Eclipse by renaming a Junit test file.
In my Eclipse work space I have an App project and a Test project.
The Test project has the App project as a required project on the build path.

Started getting the NoSuchMethodError.
Then I realized the class in the Test project had the same name as the class in the App project.

App/  
  src/
     com.example/  
       Projection.java
Test/  
  src/
     com.example/
       Projection.java

After renaming the Test to the correct name "ProjectionTest.java" the exception went away.

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

Object.keys(myObj).length === 0;

As there is need to just check if Object is empty it will be better to directly call a native method Object.keys(myObj).length which returns the array of keys by internally iterating with for..in loop.As Object.hasOwnProperty returns a boolean result based on the property present in an object which itself iterates with for..in loop and will have time complexity O(N2).

On the other hand calling a UDF which itself has above two implementations or other will work fine for small object but will block the code which will have severe impact on overall perormance if Object size is large unless nothing else is waiting in the event loop.

sed is a stream editor. It works with streams of characters on a per-line basis. It has a primitive programming language that includes goto-style loops and simple conditionals (in addition to pattern matching and address matching). There are essentially only two "variables": pattern space and hold space. Readability of scripts can be difficult. Mathematical operations are extraordinarily awkward at best.

There are various versions of sed with different levels of support for command line options and language features.

awk is oriented toward delimited fields on a per-line basis. It has much more robust programming constructs including if/else, while, do/while and for (C-style and array iteration). There is complete support for variables and single-dimension associative arrays plus (IMO) kludgey multi-dimension arrays. Mathematical operations resemble those in C. It has printf and functions. The "K" in "AWK" stands for "Kernighan" as in "Kernighan and Ritchie" of the book "C Programming Language" fame (not to forget Aho and Weinberger). One could conceivably write a detector of academic plagiarism using awk.

GNU awk (gawk) has numerous extensions, including true multidimensional arrays in the latest version. There are other variations of awk including mawk and nawk.

Both programs use regular expressions for selecting and processing text.

I would tend to use sed where there are patterns in the text. For example, you could replace all the negative numbers in some text that are in the form "minus-sign followed by a sequence of digits" (e.g. "-231.45") with the "accountant's brackets" form (e.g. "(231.45)") using this (which has room for improvement):

sed 's/-\([0-9.]\+\)/(\1)/g' inputfile

I would use awk when the text looks more like rows and columns or, as awk refers to them "records" and "fields". If I was going to do a similar operation as above, but only on the third field in a simple comma delimited file I might do something like:

awk -F, 'BEGIN {OFS = ","} {gsub("-([0-9.]+)", "(" substr($3, 2) ")", $3); print}' inputfile

Of course those are just very simple examples that don't illustrate the full range of capabilities that each has to offer.

You can use a tuple for a lot of things where you would use a struct in C (something like x,y coordinates or RGB colors for example).

For everything else you can use dictionary, or a utility class like this one:

>>> class Bunch:
...     def __init__(self, **kwds):
...         self.__dict__.update(kwds)
...
>>> mystruct = Bunch(field1=value1, field2=value2)

I think the "definitive" discussion is here, in the published version of the Python Cookbook.

Lodash version 3.10.1

Methods compared

• _.merge(object, [sources], [customizer], [thisArg])
• _.assign(object, [sources], [customizer], [thisArg])
• _.extend(object, [sources], [customizer], [thisArg])
• _.defaults(object, [sources])
• _.defaultsDeep(object, [sources])

Similarities

• None of them work on arrays as you might expect
• _.extend is an alias for _.assign, so they are identical
• All of them seem to modify the target object (first argument)
• All of them handle null the same

Differences

• _.defaults and _.defaultsDeep processes the arguments in reverse order compared to the others (though the first argument is still the target object)
• _.merge and _.defaultsDeep will merge child objects and the others will overwrite at the root level
• Only _.assign and _.extend will overwrite a value with undefined

Tests

They all handle members at the root in similar ways.

_.assign      ({}, { a: 'a' }, { a: 'bb' }) // => { a: "bb" }
_.merge       ({}, { a: 'a' }, { a: 'bb' }) // => { a: "bb" }
_.defaults    ({}, { a: 'a' }, { a: 'bb' }) // => { a: "a"  }
_.defaultsDeep({}, { a: 'a' }, { a: 'bb' }) // => { a: "a"  }

_.assign handles undefined but the others will skip it

_.assign      ({}, { a: 'a'  }, { a: undefined }) // => { a: undefined }
_.merge       ({}, { a: 'a'  }, { a: undefined }) // => { a: "a" }
_.defaults    ({}, { a: undefined }, { a: 'bb' }) // => { a: "bb" }
_.defaultsDeep({}, { a: undefined }, { a: 'bb' }) // => { a: "bb" }

They all handle null the same

_.assign      ({}, { a: 'a'  }, { a: null }) // => { a: null }
_.merge       ({}, { a: 'a'  }, { a: null }) // => { a: null }
_.defaults    ({}, { a: null }, { a: 'bb' }) // => { a: null }
_.defaultsDeep({}, { a: null }, { a: 'bb' }) // => { a: null }

But only _.merge and _.defaultsDeep will merge child objects

_.assign      ({}, {a:{a:'a'}}, {a:{b:'bb'}}) // => { "a": { "b": "bb" }}
_.merge       ({}, {a:{a:'a'}}, {a:{b:'bb'}}) // => { "a": { "a": "a", "b": "bb" }}
_.defaults    ({}, {a:{a:'a'}}, {a:{b:'bb'}}) // => { "a": { "a": "a" }}
_.defaultsDeep({}, {a:{a:'a'}}, {a:{b:'bb'}}) // => { "a": { "a": "a", "b": "bb" }}

And none of them will merge arrays it seems

_.assign      ({}, {a:['a']}, {a:['bb']}) // => { "a": [ "bb" ] }
_.merge       ({}, {a:['a']}, {a:['bb']}) // => { "a": [ "bb" ] }
_.defaults    ({}, {a:['a']}, {a:['bb']}) // => { "a": [ "a"  ] }
_.defaultsDeep({}, {a:['a']}, {a:['bb']}) // => { "a": [ "a"  ] }

All modify the target object

a={a:'a'}; _.assign      (a, {b:'bb'}); // a => { a: "a", b: "bb" }
a={a:'a'}; _.merge       (a, {b:'bb'}); // a => { a: "a", b: "bb" }
a={a:'a'}; _.defaults    (a, {b:'bb'}); // a => { a: "a", b: "bb" }
a={a:'a'}; _.defaultsDeep(a, {b:'bb'}); // a => { a: "a", b: "bb" }

None really work as expected on arrays

Note: As @Mistic pointed out, Lodash treats arrays as objects where the keys are the index into the array.

_.assign      ([], ['a'], ['bb']) // => [ "bb" ]
_.merge       ([], ['a'], ['bb']) // => [ "bb" ]
_.defaults    ([], ['a'], ['bb']) // => [ "a"  ]
_.defaultsDeep([], ['a'], ['bb']) // => [ "a"  ]

_.assign      ([], ['a','b'], ['bb']) // => [ "bb", "b" ]
_.merge       ([], ['a','b'], ['bb']) // => [ "bb", "b" ]
_.defaults    ([], ['a','b'], ['bb']) // => [ "a", "b"  ]
_.defaultsDeep([], ['a','b'], ['bb']) // => [ "a", "b"  ]

Console.OutputEncoding Property

https://docs.microsoft.com/en-us/dotnet/api/system.console.outputencoding

Note that successfully displaying Unicode characters to the console requires the following:

• The console must use a TrueType font, such as Lucida Console or Consolas, to display characters.

There is a operator < between lists e.g.:

[12, 'tall', 'blue', 1] < [4, 'tall', 'blue', 13]

will give

False

For all struggling around with the #selector in Swift 3 or Swift 4, here a full code example:

// WE NEED A CLASS THAT SHOULD RECEIVE NOTIFICATIONS
    class MyReceivingClass {

    // ---------------------------------------------
    // INIT -> GOOD PLACE FOR REGISTERING
    // ---------------------------------------------
    init() {
        // WE REGISTER FOR SYSTEM NOTIFICATION (APP WILL RESIGN ACTIVE)

        // Register without parameter
        NotificationCenter.default.addObserver(self, selector: #selector(MyReceivingClass.handleNotification), name: .UIApplicationWillResignActive, object: nil)

        // Register WITH parameter
        NotificationCenter.default.addObserver(self, selector: #selector(MyReceivingClass.handle(withNotification:)), name: .UIApplicationWillResignActive, object: nil)
    }

    // ---------------------------------------------
    // DE-INIT -> LAST OPTION FOR RE-REGISTERING
    // ---------------------------------------------
    deinit {
        NotificationCenter.default.removeObserver(self)
    }

    // either "MyReceivingClass" must be a subclass of NSObject OR selector-methods MUST BE signed with '@objc'

    // ---------------------------------------------
    // HANDLE NOTIFICATION WITHOUT PARAMETER
    // ---------------------------------------------
    @objc func handleNotification() {
        print("RECEIVED ANY NOTIFICATION")
    }

    // ---------------------------------------------
    // HANDLE NOTIFICATION WITH PARAMETER
    // ---------------------------------------------
    @objc func handle(withNotification notification : NSNotification) {
        print("RECEIVED SPECIFIC NOTIFICATION: \(notification)")
    }
}

In this example we try to get POSTs from AppDelegate (so in AppDelegate implement this):

// ---------------------------------------------
// WHEN APP IS GOING TO BE INACTIVE
// ---------------------------------------------
func applicationWillResignActive(_ application: UIApplication) {

    print("POSTING")

    // Define identifiyer
    let notificationName = Notification.Name.UIApplicationWillResignActive

    // Post notification
    NotificationCenter.default.post(name: notificationName, object: nil)
}

You can avoid declaration of global variables by adding them directly to the global object:

(function(global) {

  ...

  global.varName = someValue;

  ...

}(this));

A disadvantage of this method is that global.varName won't exist until that specific line of code is executed, but that can be easily worked around.

You might also consider an application architecture where such globals are held in a closure common to all functions that need them, or as properties of a suitably accessible data storage object.

<?php //-- Very simple variant
$useragent = $_SERVER['HTTP_USER_AGENT']; 
$iPod = stripos($useragent, "iPod"); 
$iPad = stripos($useragent, "iPad"); 
$iPhone = stripos($useragent, "iPhone");
$Android = stripos($useragent, "Android"); 
$iOS = stripos($useragent, "iOS");
//-- You can add billion devices 

$DEVICE = ($iPod||$iPad||$iPhone||$Android||$iOS||$webOS||$Blackberry||$IEMobile||$OperaMini);

if ($DEVICE !=true) {?>

<!-- What you want for all non-mobile devices. Anything with all HTML codes-->

<?php }else{ ?> 

<!-- What you want for all mobile devices. Anything with all HTML codes --> 
<?php } ?>

Detect if a target attribute was used and contains "_blank". For mobile devices that don't like "_blank", this is a reliable alternative.

    $('.someSelector').bind('touchend click', function() {

        var url = $('a', this).prop('href');
        var target = $('a', this).prop('target');

        if(url) {
            // # open in new window if "_blank" used
            if(target == '_blank') { 
                window.open(url, target);
            } else {
                window.location = url;
            }
        }           
    });

example you wanted to delete the subject record with its subject_id

@RequestMapping(value="subject_setup/delete/{subjectid}",method = RequestMethod.GET)
public ModelAndView delete(@PathVariable int subjectid) {
    subjectsDao.delete(subjectid);
    return new ModelAndView("redirect:/subject_setup");
}

and the parameter will be used for input on your query

public int delete(int subjectid) {
    String sql = "update tbl_subject set isdeleted= '1' where id = "+subjectid+"";
    return template.update(sql);
}

Try ISDATE() function in SQL Server. If 1, select valid date. If 0 selects invalid dates.

SELECT cast(CONVERT(varchar, LoginTime, 101) as datetime)  
FROM AuditTrail 
WHERE ISDATE(LoginTime) = 1

• Click here to view result

EDIT :

As per your update i need to extract the date only and remove the time, then you could simply use the inner CONVERT

SELECT CONVERT(VARCHAR, LoginTime, 101) FROM AuditTrail 

or

SELECT LEFT(LoginTime,10) FROM AuditTrail

EDIT 2 :

The major reason for the error will be in your date in WHERE clause.ie,

SELECT cast(CONVERT(varchar, LoginTime, 101) as datetime)  
FROM AuditTrail
where CAST(CONVERT(VARCHAR, LoginTime, 101) AS DATE) <= 
CAST('06/18/2012' AS DATE)

will be different from

SELECT cast(CONVERT(varchar, LoginTime, 101) as datetime)  
FROM AuditTrail
where CAST(CONVERT(VARCHAR, LoginTime, 101) AS DATE) <= 
CAST('18/06/2012' AS DATE)

CONCLUSION

In EDIT 2 the first query tries to filter in mm/dd/yyyy format, while the second query tries to filter in dd/mm/yyyy format. Either of them will fail and throws error

The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.

So please make sure to filter date either with mm/dd/yyyy or with dd/mm/yyyy format, whichever works in your db.

status: this has been seen as recently as Mac OS 10.8 and Xcode 4.4.

tl;dr: This can occur in two contexts: when running on the device and when running on the simulator. When running on the device, disconnecting and reconnecting the device seems to fix things.

Mike Ash suggested

launchctl list|grep UIKitApplication|awk '{print $3}'|xargs launchctl remove

This doesn't work all the time. In fact, it's never worked for me but it clearly works in some cases. Just don't know which cases. So it's worth trying.

Otherwise, the only known way to fix this is to restart the user launchd. Rebooting will do that but there is a less drastic/faster way. You'll need to create another admin user, but you only have to do that once. When things wedge, log out as yourself, log in as that user, and kill the launchd that belongs to your main user, e.g.,

sudo kill -9 `ps aux | egrep 'user_id .*[0-9] /sbin/launchd' | awk '{print $2}'`

substituting your main user name for user_id. Logging in again as your normal user gets you back to a sane state. Kinda painful, but less so than a full reboot.

details:

This has started happening more often with Lion/Xcode 4.2. (Personally, I never saw it before that combination.)

The bug seems to be in launchd, which inherits the app process as a child when the debugger stops debugging it without killing it. This is usually signaled by the app becoming a zombie, having a process status of Z in ps.

The core issue appears to be in the bootstrap name server which is implemented in launchd. This (to the extent I understand it) maps app ids to mach ports. When the bug is triggered, the app dies but doesn't get cleaned out of the bootstrap server's name server map and as result, the bootstrap server refuses to allow another instance of the app to be registered under the same name.

It was hoped (see the comments) that forcing launchd to wait() for the zombie would fix things but it doesn't. It's not the zombie status that's the core problem (which is why some zombies are benign) but the bootstrap name server and there's no known way to clear this short of killing launchd.

It looks like the bug is triggered by something bad between Xcode, gdb, and the user launchd. I just repeated the wedge by running an app in the iphone simulator, having it stopped within gdb, and then doing a build and run to the ipad simulator. It seems to be sensitive to switching simulators (iOS 4.3/iOS 5, iPad/iPhone). It doesn't happen all the time but fairly frequently when I'm switching simulators a lot.

Killing launchd while you're logged in will screw up your session. Logging out and logging back in doesn't kill the user launchd; OS X keeps the existing process around. A reboot will fix things, but that's painful. The instructions above are faster.

I've submitted a bug to Apple, FWIW. rdar://10330930

If you can, swap out the ArrayList for an ArrayDeque, which has convenient methods like removeLast.

The simpler way:

h = ''
i = None
j = 0
k = 1
print h or i or j or k

Will print 1

print k or j or i or h

Will print 1

Code and github repo here

perhaps this is what you're looking for: https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/colors.xml

There is probably a more efficient solution to your question, but following formula should do the trick:

=SUM(COUNTIFS(J1:J196,"agree",A1:A196,"yes"),COUNTIFS(J1:J196,"agree",A1:A196,"no"))

Keep both lists x and y in sorted order.

If x = y, do your action, if x < y, advance x, if y < x, advance y until either list is empty.

The run time of this intersection is proportional to min (size (x), size (y))

Don't run a .Contains () loop, this is proportional to x * y which is much worse.

I think you may be getting tripped up on the sheet protection. I streamlined your code a little and am explicitly setting references to the workbook and worksheet objects. In your example, you explicitly refer to the workbook and sheet when you're setting the TxtRng object, but not when you unprotect the sheet.

Try this:

Sub varchanger()

    Dim wb As Workbook
    Dim ws As Worksheet
    Dim TxtRng  As Range

    Set wb = ActiveWorkbook
    Set ws = wb.Sheets("Sheet1")
    'or ws.Unprotect Password:="yourpass"
    ws.Unprotect

    Set TxtRng = ws.Range("A1")
    TxtRng.Value = "SubTotal"
    'http://stackoverflow.com/questions/8253776/worksheet-protection-set-using-ws-protect-but-doesnt-unprotect-using-the-menu
    ' or ws.Protect Password:="yourpass"
    ws.Protect

End Sub

If I run the sub with ws.Unprotect commented out, I get a run-time error 1004. (Assuming I've protected the sheet and have the range locked.) Uncommenting the line allows the code to run fine.

NOTES:

1. I'm re-setting sheet protection after writing to the range. I'm assuming you want to do this if you had the sheet protected in the first place. If you are re-setting protection later after further processing, you'll need to remove that line.
2. I removed the error handler. The Excel error message gives you a lot more detail than Err.number. You can put it back in once you get your code working and display whatever you want. Obviously you can use Err.Description as well.
3. The Cells(1, 1) notation can cause a huge amount of grief. Be careful using it. Range("A1") is a lot easier for humans to parse and tends to prevent forehead-slapping mistakes.

To take a screenshot of your app:

1. Start your app as described in Run your App in Debug Mode.
2. Click Android to open the Android DDMS tool window.
3. Click Screen Capture on the left side of the Android DDMS tool window.
4. Optional: To add a device frame around your screenshot, enable the Frame screenshot option.
5. Click Save.

I like how the pycron package solves this problem.

import pycron
import time

while True:
    if pycron.is_now('0 2 * * 0'):   # True Every Sunday at 02:00
        print('running backup')
        time.sleep(60)               # The process should take at least 60 sec
                                     # to avoid running twice in one minute
    else:
        time.sleep(15)               # Check again in 15 seconds

I found myself in this situation when I tried to rebase a branch that was tracking a remote branch, and I was trying to rebase it on master. In this scenario if you try to rebase, you'll most likely find your branch diverged and it can create a mess that isn't for git nubees!

Let's say you are on branch my_remote_tracking_branch, which was branched from master

$ git status

# On branch my_remote_tracking_branch

nothing to commit (working directory clean)

And now you are trying to rebase from master as:

git rebase master

STOP NOW and save yourself some trouble! Instead, use merge as:

git merge master

Yes, you'll end up with extra commits on your branch. But unless you are up for "un-diverging" branches, this will be a much smoother workflow than rebasing. See this blog for a much more detailed explanation.

On the other hand, if your branch is only a local branch (i.e. not yet pushed to any remote) you should definitely do a rebase (and your branch will not diverge in this case).

Now if you are reading this because you already are in a "diverged" scenario due to such rebase, you can get back to the last commit from origin (i.e. in an un-diverged state) by using:

git reset --hard origin/my_remote_tracking_branch

You can't databind to a property and then explictly assign a value to the databound property.

SET string=bath Abath Bbath XYZbathABC
SET modified=%string:bath=hello%
ECHO %string%
ECHO %modified%

EDIT

Didn't see at first that you wanted the replacement to be preceded by reading the string from a file.

Well, with a batch file you don't have much facility of working on files. In this particular case, you'd have to read a line, perform the replacement, then output the modified line, and then... What then? If you need to replace all the ocurrences of 'bath' in all the file, then you'll have to use a loop:

@ECHO OFF
SETLOCAL DISABLEDELAYEDEXPANSION
FOR /F %%L IN (file.txt) DO (
  SET "line=%%L"
  SETLOCAL ENABLEDELAYEDEXPANSION
  ECHO !line:bath=hello!
  ENDLOCAL
)
ENDLOCAL

You can add a redirection to a file:

  ECHO !line:bath=hello!>>file2.txt

Or you can apply the redirection to the batch file. It must be a different file.

EDIT 2

Added proper toggling of delayed expansion for correct processing of some characters that have special meaning with batch script syntax, like !, ^ et al. (Thanks, jeb!)

After closing and reopening VS, this should resolve.

Don't know if it will shrink it, but after I run git clean, I often do git repack -ad as well, which reduces the number of pack files.

I had this issue with MacOS. I had to uncheck "use download cache" under Android SDK Manager preferences. This worked. I also recreated the cache folder and set my user as the owner then check user download cache. This also worked.

I think the only way to do this is to run another machine in parallel and use that machine to issue commands to your android box similar to how you would with a phone. If you have issues with the IP changing you can reserve an ip on your router and have the machine grab that one instead of asking the routers DHCP for one. This way you can ping the machine and figure out if it's done rebooting to continue the script.

Here is one solution that I would not recommend, but might be useful in some situations where modules were simply not generated:

import os
import sys
parent_dir_name = os.path.dirname(os.path.dirname(os.path.realpath(__file__)))
sys.path.append(parent_dir_name + "/your_dir")
import your_script
your_script.a_function()

For me it was just a problem of permissions on the persistent redis data folder. I gave it a:

chmod 777 -Rf data/

And it's works ! May be it's early to say it's resolve the issue. Because I also suspect that redis is not executing as root so I need to inspect my dockerFile to figure out more.

You could always use "%p" in order to display 8 bit hex numbers.

int main (void)
{
    uint8_t a;
    uint32_t b;
    a=15;
    b=a<<28;
    printf("%p", b);
    return 0;
}

Output:

0xf0000000

Just was working on a TextView inside a layout inside a RecyclerView. I had text getting cut off, ex, for Read this message, I saw: Read this. I tried setting android:maxLines="2" on the TextView, but nothing changed. However, android:lines="2" resulted in Read this on first line and message on the 2nd.

Comparator in line ...

List<Object> objList = findObj(name);
Collections.sort(objList, new Comparator<Object>() {
    @Override
    public int compare(Object a1, Object a2) {
        return a1.getType().compareToIgnoreCase(a2.getType());
    }
});

You don't have to do this locally either. You can do it through a remote repository, for example:

svn export http://<repo>/process/test.txt /path/to/code/

I had a situation where we had dates instead of datetimes, and the dates could overlap only on start/end. Example below:

(Green is the current interval, blue blocks are valid intervals, red ones are overlapping intervals).

I adapted Ian Nelson's answer to the following solution:

   (startB <= startA && endB > startA)
|| (startB >= startA && startB < endA)

This matches all overlap cases but ignores the allowed overlap ones.

In Java 8, Arrays.parallelSetAll seems ready made for this purpose:

import java.util.Arrays;

Arrays.parallelSetAll(array, (i) -> array[i].trim());

This will modify the original array in place, replacing each element with the result of the lambda expression.

Im not sure If this will help anyone but I was getting this error (although I was using php to create it instead of the command line) and to fix it I had to ensure that no old .key or .pem files were in the directory I was looking at.

You can use CSS to set the opacity, and than use javascript to apply the styles to a certain element in the DOM.

.opClass {
    opacity:0.4;
    filter:alpha(opacity=40); /* For IE8 and earlier */
}

Than use (for example) jQuery to change the style:

$('#element_id').addClass('opClass');

Or with plain javascript, like this:

document.getElementById("element_id").className = "opClass";

As an extension to Ignacio Vazquez-Abrams' answer

>>> u'a?ä'.encode('ascii', 'ignore')
'a'

It is sometimes desirable to remove accents from characters and print the base form. This can be accomplished with

>>> import unicodedata
>>> unicodedata.normalize('NFKD', u'a?ä').encode('ascii', 'ignore')
'aa'

You may also want to translate other characters (such as punctuation) to their nearest equivalents, for instance the RIGHT SINGLE QUOTATION MARK unicode character does not get converted to an ascii APOSTROPHE when encoding.

>>> print u'\u2019'
’
>>> unicodedata.name(u'\u2019')
'RIGHT SINGLE QUOTATION MARK'
>>> u'\u2019'.encode('ascii', 'ignore')
''
# Note we get an empty string back
>>> u'\u2019'.replace(u'\u2019', u'\'').encode('ascii', 'ignore')
"'"

Although there are more efficient ways to accomplish this. See this question for more details Where is Python's "best ASCII for this Unicode" database?

The reason that your HTML is replaced is because of an evil JavaScript function: document.write().

It is most definitely "bad form." It only works with webpages if you use it on the page load; and if you use it during runtime, it will replace your entire document with the input. And if you're applying it as strict XHTML structure it's not even valid code.

the problem:

document.write writes to the document stream. Calling document.write on a closed (or loaded) document automatically calls document.open which will clear the document.

-- quote from the MDN

document.write() has two henchmen, document.open(), and document.close(). When the HTML document is loading, the document is "open". When the document has finished loading, the document has "closed". Using document.write() at this point will erase your entire (closed) HTML document and replace it with a new (open) document. This means your webpage has erased itself and started writing a new page - from scratch.

I believe document.write() causes the browser to have a performance decrease as well (correct me if I am wrong).

an example:

This example writes output to the HTML document after the page has loaded. Watch document.write()'s evil powers clear the entire document when you press the "exterminate" button:

I am an ordinary HTML page.  I am innocent, and purely for informational purposes. Please do not <input type="button" onclick="document.write('This HTML page has been succesfully exterminated.')" value="exterminate"/>_x000D_
me!

the alternatives:

• .innerHTML This is a wonderful alternative, but this attribute has to be attached to the element where you want to put the text.

Example: document.getElementById('output1').innerHTML = 'Some text!';

• .createTextNode() is the alternative recommended by the W3C.

Example: var para = document.createElement('p'); para.appendChild(document.createTextNode('Hello, '));

NOTE: This is known to have some performance decreases (slower than .innerHTML). I recommend using .innerHTML instead.

the example with the .innerHTML alternative:

I am an ordinary HTML page. _x000D_
I am innocent, and purely for informational purposes. _x000D_
Please do not _x000D_
<input type="button" onclick="document.getElementById('output1').innerHTML = 'There was an error exterminating this page. Please replace <code>.innerHTML</code> with <code>document.write()</code> to complete extermination.';" value="exterminate"/>_x000D_
 me!_x000D_
<p id="output1"></p>

There seem to be several ways to create/fix this issue. For me, the CRM product I am using was written in native code and is able to call my .NET dll, but I run into the configuration information needing to be at/above the main application. For me, the CRM application isn't .NET, so I ended up having to put it in my machine.config file (not where I want it). In addition, since my company uses Websense I had a hard time even adding the Service Reference due to a 407 Proxy Authentication Required issue, that to required a modification to the machine.cong.

Proxy solution:

To get the WCF Service Reference to work I had to copy the information from the app.config of my DLL to the main application config (but for me that was machine.config). And I also had to copy the endpoint information to that same file. Once I did that it starting working for me.

If you want to use the call operator, the arguments can be an array stored in a variable:

$prog = 'c:\windows\system32\cmd.exe'
$myargs = '/c','dir','/x'
& $prog $myargs

The call operator works with ApplicationInfo objects too.

$prog = get-command cmd
$myargs = -split '/c dir /x'
& $prog $myargs

This is Similar to what Meritt has posted earlier. just posting the complete code

    string sJSON;
    Dictionary<string, string> aa1 = new Dictionary<string, string>();
    aa1.Add("one", "1"); aa1.Add("two", "2"); aa1.Add("three", "3");
    Console.Write("JSON form of Person object: ");

    sJSON = WriteFromObject(aa1);
    Console.WriteLine(sJSON);

    Dictionary<string, string> aaret = new Dictionary<string, string>();
    aaret = ReadToObject<Dictionary<string, string>>(sJSON);

    public static string WriteFromObject(object obj)
    {            
        byte[] json;
            //Create a stream to serialize the object to.  
        using (MemoryStream ms = new MemoryStream())
        {                
            // Serializer the object to the stream.  
            DataContractJsonSerializer ser = new DataContractJsonSerializer(obj.GetType());
            ser.WriteObject(ms, obj);
            json = ms.ToArray();
            ms.Close();
        }
        return Encoding.UTF8.GetString(json, 0, json.Length);

    }

    // Deserialize a JSON stream to object.  
    public static T ReadToObject<T>(string json) where T : class, new()
    {
        T deserializedObject = new T();
        using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json)))
        {

            DataContractJsonSerializer ser = new DataContractJsonSerializer(deserializedObject.GetType());
            deserializedObject = ser.ReadObject(ms) as T;
            ms.Close();
        }
        return deserializedObject;
    }

Simple solution in 2 lines of code. Just use the copy constructor. No need to write TrulyObservableCollection etc.

Example:

        speakers.list[0].Status = "offline";
        speakers.list[0] = new Speaker(speakers.list[0]);

Another method without copy constructor. You can use serialization.

        speakers.list[0].Status = "offline";
        //speakers.list[0] = new Speaker(speakers.list[0]);
        var tmp  = JsonConvert.SerializeObject(speakers.list[0]);
        var tmp2 = JsonConvert.DeserializeObject<Speaker>(tmp);
        speakers.list[0] = tmp2;

Hold down the Option key and click where you'd like the cursor to move, and Terminal rushes the cursor that precise spot.

I agree with above answer. But here is another way of CSS compression.

You can concat your CSS by using YUI compressor:

module.exports = function(grunt) {
  var exec = require('child_process').exec;
   grunt.registerTask('cssmin', function() {
    var cmd = 'java -jar -Xss2048k '
      + __dirname + '/../yuicompressor-2.4.7.jar --type css '
      + grunt.template.process('/css/style.css') + ' -o '
      + grunt.template.process('/css/style.min.css')
    exec(cmd, function(err, stdout, stderr) {
      if(err) throw err;
    });
  });
}; 

The issue is that even though we add a folder to skip list it will be deleted if it does not exist.

The solution is to add both the destination and the source folder with full path.

I will try to explain the different scenarios and what happens below, based on my experience.

Starting folder structure:

d:\Temp\source\1.txt
d:\Temp\source\2\2.txt

Command:

robocopy D:\Temp\source D:\Temp\dest /MIR

This will copy over all the files and folders that are missing and deletes all the files and folders that cannot be found in the source

Let's add a new folder and then add it to the command to skip it.

New structure:

d:\Temp\source\1.txt
d:\Temp\source\2\2.txt
d:\Temp\source\3\3.txt

Command:

robocopy D:\Temp\source D:\Temp\dest /MIR /XD "D:\Temp\source\3"        

If I add /XD with the source folder and run the command it all seems good the command it wont copy it over.

Now add a folder to the destination to get this setup:

d:\Temp\source\1.txt
d:\Temp\source\2\2.txt
d:\Temp\source\3\3.txt

d:\Temp\dest\1.txt
d:\Temp\dest\2\2.txt
d:\Temp\dest\3\4.txt

If I run the command it is still fine, 4.txt stays there 3.txt is not copied over. All is fine.

But, if I delete the source folder "d:\Temp\source\3" then the destination folder and the file are deleted even though it is on the skip list

                       1    D:\Temp\source\
    *EXTRA Dir        -1    D:\Temp\dest\3\
      *EXTRA File                  4        4.txt
                       1    D:\Temp\source\2\

If I change the command to skip the destination folder instead then the folder is not deleted, when the folder is missing from the source.

robocopy D:\Temp\source D:\Temp\dest /MIR /XD "D:\Temp\dest\3"

On the other hand if the folder exists and there are files it will copy them over and delete them:

                       1    D:\Temp\source\3\
          *EXTRA File                  4        4.txt
100%        New File                   4        3.txt

To make sure the folder is always skipped and no files are copied over even if the source or destination folder is missing we have to add both to the skip list:

robocopy D:\Temp\source D:\Temp\dest /MIR /XD "d:\Temp\source\3" "D:\Temp\dest\3"

After this no matters if the source folder is missing or the destination folder is missing, robocopy will leave it as it is.

There are many ways. Here are at least five:

/*

    std::string s0;
    const char *s1;
    char *s2;
    char *s3;
    char *s4;
    char *s5;

    // This is the initial C++ string.
    s0 = "hello";

    // Method #1: Just use "c_str()" method to obtain a pointer to a

    // Be careful though because when `s0` goes out of scope, s1 points

    // original string. Keep in mind that once a current function returns,
    // the memory is invalidated.
    s2 = (char *)alloca(s0.size() + 1);
    memcpy(s2, s0.c_str(), s0.size() + 1);

    // Method #3: Allocate memory dynamically and copy the content of the

You can set this using the Sys.setenv() function. My R session defaults to English, so I'll set it to French and then back again:

> Sys.setenv(LANG = "fr")
> 2 + x
Erreur : objet 'x' introuvable
> Sys.setenv(LANG = "en")
> 2 + x
Error: object 'x' not found

A list of the abbreviations can be found here.

Sys.getenv() gives you a list of all the environment variables that are set.

Your sample code seems to be OK. Thus, the root problem needs to be dug up somehow. Let's eliminate chance for typos in the script. First off, make sure you put Set-Strictmode -Version 2.0 in the beginning of your script. This will help you to catch misspelled variable names. Like so,

# Test.ps1
set-strictmode -version 2.0 # Comment this line and no error will be reported.
$foo = "bar"
set-content -path ./test.txt -value $fo # Error! Should be "$foo"

PS C:\temp> .\test.ps1
The variable '$fo' cannot be retrieved because it has not been set.
At C:\temp\test.ps1:3 char:40
+ set-content -path ./test.txt -value $fo <<<<
    + CategoryInfo          : InvalidOperation: (fo:Token) [], RuntimeException
    + FullyQualifiedErrorId : VariableIsUndefined

The next part about question marks sounds like you have a problem with Unicode. What's the output when you type the file with Powershell like so,

$file = "\\server\share\file.txt"
cat $file

I got this error while running the command using pip3. I have python 3.6 installed on windows. I was trying this-

pip3 install PACKAGENAME

It gave error. The solution in this particular case is simply to run the command as pip.

pip install PACKAGENAME

Try to use ; instead of GO. It worked for me for 2008 R2 version

In Java 8 you can use Files.write() method with two arguments: Path and List<String>, something like this:

List<String> clubNames = clubs.stream()
    .map(Club::getName)
    .collect(Collectors.toList())

try {
    Files.write(Paths.get(fileName), clubNames);
} catch (IOException e) {
    log.error("Unable to write out names", e);
}

In Git, to "fast forward" means to update the HEAD pointer in such a way that its new value is a direct descendant of the prior value. In other words, the prior value is a parent, or grandparent, or grandgrandparent, ...

Fast forwarding is not possible when the new HEAD is in a diverged state relative to the stream you want to integrate. For instance, you are on master and have local commits, and git fetch has brought new upstream commits into origin/master. The branch now diverges from its upstream and cannot be fast forwarded: your master HEAD commit is not an ancestor of origin/master HEAD. To simply reset master to the value of origin/master would discard your local commits. The situation requires a rebase or merge.

If your local master has no changes, then it can be fast-forwarded: simply updated to point to the same commit as the latestorigin/master. Usually, no special steps are needed to do fast-forwarding; it is done by merge or rebase in the situation when there are no local commits.

Is it ok to assume that fast-forward means all commits are replayed on the target branch and the HEAD is set to the last commit on that branch?

No, that is called rebasing, of which fast-forwarding is a special case when there are no commits to be replayed (and the target branch has new commits, and the history of the target branch has not been rewritten, so that all the commits on the target branch have the current one as their ancestor.)

You have to just add the index_col=False parameter

df1 = pd.read_csv('foo.csv',
     header=0,
     index_col=False,
     names=["dummy", "date", "loc", "x"], 
     usecols=["dummy", "date", "loc", "x"],
     parse_dates=["date"])
  print df1

Disable horizontal scrollbar completely by adding this code.

body{
  overflow-x: hidden;
  overflow-y: scroll;
}

If I understand your problem correctly you may have bigger issues. You said that other objects may subscribe to these events. When the object is serialized and deserialized the other objects (the ones that you don't have control of) will lose their event handlers.

If you're not worried about that then keeping a reference to your event handler should be good enough. If you are worried about the side-effects of other objects losing their event handlers, then you may want to rethink your caching strategy.

you have an extra "}" in each object, you may write the json string like this:

public class ShowActivity {   
    private final static String  jString = "{" 
    + "    \"geodata\": [" 
    + "        {" 
    + "                \"id\": \"1\"," 
    + "                \"name\": \"Julie Sherman\","                  
    + "                \"gender\" : \"female\"," 
    + "                \"latitude\" : \"37.33774833333334\"," 
    + "                \"longitude\" : \"-121.88670166666667\""            
    + "                }" 
    + "        }," 
    + "        {" 
    + "                \"id\": \"2\"," 
    + "                \"name\": \"Johnny Depp\","          
    + "                \"gender\" : \"male\"," 
    + "                \"latitude\" : \"37.336453\"," 
    + "                \"longitude\" : \"-121.884985\""            
    + "                }" 
    + "        }" 
    + "    ]" 
    + "}"; 
}

If you are on a 64bit build of ubuntu or debian (see e.g. 'cat /proc/version') you should simply use the 64bit cross compilers, if you cloned

git clone https://github.com/raspberrypi/tools

then the 64bit tools are in

tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64

use that directory for the gcc-toolchain. A useful tutorial for compiling that I followed is available here Building and compiling Raspberry PI Kernel (use the -x64 path from above as ${CCPREFIX})

long __builtin_expect(long EXP, long C);

This construct tells the compiler that the expression EXP most likely will have the value C. The return value is EXP. __builtin_expect is meant to be used in an conditional expression. In almost all cases will it be used in the context of boolean expressions in which case it is much more convenient to define two helper macros:

#define unlikely(expr) __builtin_expect(!!(expr), 0)
#define likely(expr) __builtin_expect(!!(expr), 1)

These macros can then be used as in

if (likely(a > 1))

A mutex is used for serial access to a resource while a semaphore limits access to a resource up to a set number. You can think of a mutex as a semaphore with an access count of 1. Whatever you set your semaphore count to, that may threads can access the resource before the resource is blocked.

the Request.ServerVariables object works for me. I don't know of any reason not to use it.

ServerVariables["SERVER_NAME"] and ServerVariables["HTTP_URL"] should get what you're looking for

You can use {} arround your variable, to separate it from what's after:

echo "{$test}y"

As reference, you can take a look to the Variable parsing - Complex (curly) syntax section of the PHP manual.

The other answers assume that your compiler is C++11 compliant. That is fine if it is. But what if you are using an older compiler?

I picked up the following hack somewhere on the net. It works well enough for me:

  #if defined __UINT32_MAX__ or UINT32_MAX
  #include <inttypes.h>
  #else
  typedef unsigned char uint8_t;
  typedef unsigned short uint16_t;
  typedef unsigned long uint32_t;
  typedef unsigned long long uint64_t;
  #endif

It is not portable, of course. But it might work for your compiler.

In bash, contrary to [, [[ prevents word splitting of variable values.

For those who like boost:

boost::filesystem::path mySourcePath("foo.bar");
boost::filesystem::path myTargetPath("bar.foo");

// Variant 1: Overwrite existing
boost::filesystem::copy_file(mySourcePath, myTargetPath, boost::filesystem::copy_option::overwrite_if_exists);

// Variant 2: Fail if exists
boost::filesystem::copy_file(mySourcePath, myTargetPath, boost::filesystem::copy_option::fail_if_exists);

Note that boost::filesystem::path is also available as wpath for Unicode. And that you could also use

using namespace boost::filesystem

if you do not like those long type names

The ioctl function is useful for implementing a device driver to set the configuration on the device. e.g. a printer that has configuration options to check and set the font family, font size etc. ioctl could be used to get the current font as well as set the font to a new one. A user application uses ioctl to send a code to a printer telling it to return the current font or to set the font to a new one.

int ioctl(int fd, int request, ...)

1. fd is file descriptor, the one returned by open;
2. request is request code. e.g GETFONT will get the current font from the printer, SETFONT will set the font on the printer;
3. the third argument is void *. Depending on the second argument, the third may or may not be present, e.g. if the second argument is SETFONT, the third argument can be the font name such as "Arial";

int request is not just a macro. A user application is required to generate a request code and the device driver module to determine which configuration on device must be played with. The application sends the request code using ioctl and then uses the request code in the device driver module to determine which action to perform.

A request code has 4 main parts

    1. A Magic number - 8 bits
    2. A sequence number - 8 bits
    3. Argument type (typically 14 bits), if any.
    4. Direction of data transfer (2 bits).  

If the request code is SETFONT to set font on a printer, the direction for data transfer will be from user application to device driver module (The user application sends the font name "Arial" to the printer). If the request code is GETFONT, direction is from printer to the user application.

In order to generate a request code, Linux provides some predefined function-like macros.

1._IO(MAGIC, SEQ_NO) both are 8 bits, 0 to 255, e.g. let us say we want to pause printer. This does not require a data transfer. So we would generate the request code as below

#define PRIN_MAGIC 'P'
#define NUM 0
#define PAUSE_PRIN __IO(PRIN_MAGIC, NUM) 

and now use ioctl as

ret_val = ioctl(fd, PAUSE_PRIN);

The corresponding system call in the driver module will receive the code and pause the printer.

2. __IOW(MAGIC, SEQ_NO, TYPE) MAGIC and SEQ_NO are the same as above, and TYPE gives the type of the next argument, recall the third argument of ioctl is void *. W in __IOW indicates that the data flow is from user application to driver module. As an example, suppose we want to set the printer font to "Arial".

#define PRIN_MAGIC 'S'
#define SEQ_NO 1
#define SETFONT __IOW(PRIN_MAGIC, SEQ_NO, unsigned long)

further,

char *font = "Arial";
ret_val = ioctl(fd, SETFONT, font); 

Now font is a pointer, which means it is an address best represented as unsigned long, hence the third part of _IOW mentions type as such. Also, this address of font is passed to corresponding system call implemented in device driver module as unsigned long and we need to cast it to proper type before using it. Kernel space can access user space and hence this works. other two function-like macros are __IOR(MAGIC, SEQ_NO, TYPE) and __IORW(MAGIC, SEQ_NO, TYPE) where the data flow will be from kernel space to user space and both ways respectively.

Please let me know if this helps!

Pure Python (2 & 3), a snippet without 3rd party dependencies.

This function writes compressed, true-color (4 bytes per pixel) RGBA PNG's.

def write_png(buf, width, height):
    """ buf: must be bytes or a bytearray in Python3.x,
        a regular string in Python2.x.
    """
    import zlib, struct

    # reverse the vertical line order and add null bytes at the start
    width_byte_4 = width * 4
    raw_data = b''.join(
        b'\x00' + buf[span:span + width_byte_4]
        for span in range((height - 1) * width_byte_4, -1, - width_byte_4)
    )

    def png_pack(png_tag, data):
        chunk_head = png_tag + data
        return (struct.pack("!I", len(data)) +
                chunk_head +
                struct.pack("!I", 0xFFFFFFFF & zlib.crc32(chunk_head)))

    return b''.join([
        b'\x89PNG\r\n\x1a\n',
        png_pack(b'IHDR', struct.pack("!2I5B", width, height, 8, 6, 0, 0, 0)),
        png_pack(b'IDAT', zlib.compress(raw_data, 9)),
        png_pack(b'IEND', b'')])

... The data should be written directly to a file opened as binary, as in:

data = write_png(buf, 64, 64)
with open("my_image.png", 'wb') as fh:
    fh.write(data)

Each python object has a __dict__ atttribute which is a dictionary containing all other attributes. e.g. when you type self.attr python is actually doing self.__dict__['attr']. As you can imagine using a dictionary to store attribute takes some extra space & time for accessing it.

However, when you use __slots__, any object created for that class won't have a __dict__ attribute. Instead, all attribute access is done directly via pointers.

So if want a C style structure rather than a full fledged class you can use __slots__ for compacting size of the objects & reducing attribute access time. A good example is a Point class containing attributes x & y. If you are going to have a lot of points, you can try using __slots__ in order to conserve some memory.

If the actual problem at hand is to concatenate two 1-D arrays vertically, and we are not fixated on using concatenate to perform this operation, I would suggest the use of np.column_stack:

In []: a = np.array([1,2,3])
In []: b = np.array([4,5,6])
In []: np.column_stack((a, b))
array([[1, 4],
       [2, 5],
       [3, 6]])

you can do it in such way:

sqlConnection.Open();

string sqlQuery = "INSERT INTO [dbo].[Customer]([FirstName],[LastName],[Address],[City]) VALUES (@FirstName,@LastName,@Address,@City)";
sqlConnection.Execute(sqlQuery,
    new
    {
        customerEntity.FirstName,
        customerEntity.LastName,
        customerEntity.Address,
        customerEntity.City
    });

sqlConnection.Close();

An abstract class can be used instead of an interface (in C# 7.3).

// Like interface
abstract class IIO
{
    public virtual async Task<string> DoOperation(string Name)
    {
        throw new NotImplementedException(); // throwing exception
        // return await Task.Run(() => { return ""; }); // or empty do
    }
}

// Implementation
class IOImplementation : IIO
{
    public override async Task<string> DoOperation(string Name)
    {
        return await await Task.Run(() =>
        {
            if(Name == "Spiderman")
                return "ok";
            return "cancel";
        }); 
    }
}

I've historically rolled my own access at a low level (XML generation and parsing) to deal with the occasional need to do SOAP style requests from Objective-C. That said, there's a library available called SOAPClient (soapclient) that is open source (BSD licensed) and available on Google Code (mac-soapclient) that might be of interest.

I won't attest to it's abilities or effectiveness, as I've never used it or had to work with it's API's, but it is available and might provide a quick solution for you depending on your needs.

Apple had, at one time, a very broken utility called WS-MakeStubs. I don't think it's available on the iPhone, but you might also be interested in an open-source library intended to replace that - code generate out Objective-C for interacting with a SOAP client. Again, I haven't used it - but I've marked it down in my notes: wsdl2objc

Check whether the particular port is open on the server to serve the client or not?

in Ubuntu or Linux distro

sudo ufw enable
sudo ufw allow 5000/tcp //allow the server to handle the request on port 5000

Configure the application to handle remote requests

app.run(host='0.0.0.0' , port=5000)


python3 app.py & #run application in background

you don't need to pass the entire encoded string to atob method, you need to split the encoded string and pass the required string to atob method

const token= "eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJob3NzYW0iLCJUb2tlblR5cGUiOiJCZWFyZXIiLCJyb2xlIjoiQURNSU4iLCJpc0FkbWluIjp0cnVlLCJFbXBsb3llZUlkIjoxLCJleHAiOjE2MTI5NDA2NTksImlhdCI6MTYxMjkzNzA1OX0.8f0EeYbGyxt9hjggYW1vR5hMHFVXL4ZvjTA6XgCCAUnvacx_Dhbu1OGh8v5fCsCxXQnJ8iAIZDIgOAIeE55LUw"
console.log(atob(token.split(".")[1]));

The problem is GROUP BY - if you group results by Locus, you only get one result per locus.

Try:

SELECT * FROM Genes WHERE Locus = '3' AND Chromosome = '10';

If you prefer using HAVING syntax, then GROUP BY id or something that is not repeating in the result set.

I googled this problem for quite a while, then it occurred to me that there is an Android method, android.text.util.Linkify, that utilizes some pretty robust regexes to accomplish this. Luckily, Android is open source.

They use a few different patterns for matching different types of urls. You can find them all here: http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/2.0_r1/android/text/util/Regex.java#Regex.0WEB_URL_PATTERN

If you're just concerned about url's that match the WEB_URL_PATTERN, that is, urls that conform to the RFC 1738 spec, you can use this:

/((?:(http|https|Http|Https|rtsp|Rtsp):\/\/(?:(?:[a-zA-Z0-9\$\-\_\.\+\!\*\'\(\)\,\;\?\&\=]|(?:\%[a-fA-F0-9]{2})){1,64}(?:\:(?:[a-zA-Z0-9\$\-\_\.\+\!\*\'\(\)\,\;\?\&\=]|(?:\%[a-fA-F0-9]{2})){1,25})?\@)?)?((?:(?:[a-zA-Z0-9][a-zA-Z0-9\-]{0,64}\.)+(?:(?:aero|arpa|asia|a[cdefgilmnoqrstuwxz])|(?:biz|b[abdefghijmnorstvwyz])|(?:cat|com|coop|c[acdfghiklmnoruvxyz])|d[ejkmoz]|(?:edu|e[cegrstu])|f[ijkmor]|(?:gov|g[abdefghilmnpqrstuwy])|h[kmnrtu]|(?:info|int|i[delmnoqrst])|(?:jobs|j[emop])|k[eghimnrwyz]|l[abcikrstuvy]|(?:mil|mobi|museum|m[acdghklmnopqrstuvwxyz])|(?:name|net|n[acefgilopruz])|(?:org|om)|(?:pro|p[aefghklmnrstwy])|qa|r[eouw]|s[abcdeghijklmnortuvyz]|(?:tel|travel|t[cdfghjklmnoprtvwz])|u[agkmsyz]|v[aceginu]|w[fs]|y[etu]|z[amw]))|(?:(?:25[0-5]|2[0-4][0-9]|[0-1][0-9]{2}|[1-9][0-9]|[1-9])\.(?:25[0-5]|2[0-4][0-9]|[0-1][0-9]{2}|[1-9][0-9]|[1-9]|0)\.(?:25[0-5]|2[0-4][0-9]|[0-1][0-9]{2}|[1-9][0-9]|[1-9]|0)\.(?:25[0-5]|2[0-4][0-9]|[0-1][0-9]{2}|[1-9][0-9]|[0-9])))(?:\:\d{1,5})?)(\/(?:(?:[a-zA-Z0-9\;\/\?\:\@\&\=\#\~\-\.\+\!\*\'\(\)\,\_])|(?:\%[a-fA-F0-9]{2}))*)?(?:\b|$)/gi;

If you want to be really fancy, you can test for email addresses as well. The regex for email addresses is:

/[a-zA-Z0-9\\+\\.\\_\\%\\-]{1,256}\\@[a-zA-Z0-9][a-zA-Z0-9\\-]{0,64}(\\.[a-zA-Z0-9][a-zA-Z0-9\\-]{0,25})+/gi

PS: The top level domains supported by above regex are current as of June 2007. For an up to date list you'll need to check https://data.iana.org/TLD/tlds-alpha-by-domain.txt.

The accepted answer in Swift 3:

let screenSize: CGRect = UIScreen.main.bounds
image.frame = CGRect(x: 0, y: 0, width: 50, height: screenSize.height * 0.2)

Use one of these threee variants:

SOME_PATH="/mnt/someProject/some path"
SOME_PATH='/mnt/someProject/some path'
SOME_PATH=/mnt/someProject/some\ path

I know the user asked this for Linux, but I had this issue in Windows (10 64bits) and found little information, so this is how I solved it:

• Download LIBAV, I used libav-11.3-win64.7z. Just copy "avprobe.exe" and all DLLs from "/win64/usr/bin" to where "youtube-dl.exe" is.

In case LIBAV does not help, try with FFMPEG, copying the contents of the "bin" folder to where "youtube-dl.exe" is. That did not help me, but others said it did, so it may worth a try.

Hope this helps someone having the issue in Windows.

Javascript function to search an array of tags or keywords using a search string or an array of search strings. (Uses ES5 some array method and ES6 arrow functions)

// returns true for 1 or more matches, where 'a' is an array and 'b' is a search string or an array of multiple search strings
function contains(a, b) {
    // array matches
    if (Array.isArray(b)) {
        return b.some(x => a.indexOf(x) > -1);
    }
    // string match
    return a.indexOf(b) > -1;
}

Example usage:

var a = ["a","b","c","d","e"];
var b = ["a","b"];
if ( contains(a, b) ) {
    // 1 or more matches found
}

public void setHoursWorked(){
    hoursWorked = hours;
}

You haven't defined hours inside that method. hours is not passed in as a parameter, it's not declared as a variable, and it's not being used as a class member, so you get that error.

I had a similar problem due to a password protected proxy server and couldn't find much in the way of information out there - hopefully this helps someone. I wanted to pick up the credentials as used by the customer's browser. However, the CredentialCache.DefaultCredentials and DefaultNetworkCredentials aren't working when the proxy has it's own username and password even though I had entered these details to ensure thatInternet explorer and Edge had access.

The solution for me in the end was to use a nuget package called "CredentialManagement.Standard" and the below code:

using WebClient webClient = new WebClient();    
var request = WebRequest.Create("http://google.co.uk");
var proxy = request.Proxy.GetProxy(new Uri("http://google.co.uk"));

var cmgr = new CredentialManagement.Credential() { Target = proxy.Host };
if (cmgr.Load())
{
    var credentials = new NetworkCredential(cmgr.Username, cmgr.Password);
    webClient.Proxy.Credentials = credentials;
    webClient.Credentials = credentials;
}

This grabs credentials from 'Credentials Manager' - which can be found via Windows - click Start then search for 'Credentials Manager'. Credentials for the proxy that were manually entered when prompted by the browser will be in the Windows Credentials section.

Use android:divider="#FF0000" and android:dividerHeight="2px" for ListView.

<ListView
