Use a wildcard (*) to match multiple files.

For example, the command below will delete all files with names beginning with abc.log.2012-03-.

rm -f abc.log.2012-03-*

I'd recommend running ls abc.log.2012-03-* to list the files so that you can see what you are going to delete before running the rm command.

For more details see the Bash man page on filename expansion.

find . -type f -empty -exec rm -f {} \;

Since no one yet mentioned this, in one particular case:

OLD_FILES=`echo *`
... create new files ...
rm -r $OLD_FILES

(or just rm $OLD_FILES)

or

OLD_FILES=`ls *`
... create new files ...
rm -r $OLD_FILES

You may need to use shopt -s nullglob if some files may be either there or not there:

SET_OLD_NULLGLOB=`shopt -p nullglob`
shopt -s nullglob
FILES=`echo *.sh *.bash`
$SET_OLD_NULLGLOB

without nullglob, echo *.sh *.bash may give you "a.sh b.sh *.bash".

(Having said all that, I myself prefer this answer, even though it does not work in OSX)

since answers are disappointing I would like suggest a way in which I got deleted stuff back.

I use an ide to code and accidently I used rm -rf from terminal to remove complete folder. Thanks to ide I recoved it back by reverting the change from ide's local history.

(my ide is intelliJ but all ide's support history backup)

Yes, -f is the most suitable option for this.

rm -rf *

Would remove everything (folders & files) in the current directory.

But be careful! Only execute this command if you are absolutely sure, that you are in the right directory.

find ./ -name "FOLDERNAME" | xargs rm -Rf

Should do the trick. WARNING, if you accidentally pump a . or / into xargs rm -Rf your entire computer will be deleted without an option to get it back, requiring an OS reinstall.

var Test = (from row in Dataset1.Tables[0].AsEnumerable()
            select row.Field<string>("attribute1_name") + row.Field<int>("attribute2_name")).Distinct();

There's nothing wrong with your code, the following works fine for me when I have the file.txt in the user.dir directory.

import java.io.File;
import java.util.Scanner;

public class testme {
    public static void main(String[] args) {
        System.out.println(System.getProperty("user.dir"));
        File file = new File("file.txt");
        try {
            Scanner scanner = new Scanner(file);
        } catch (Exception e) {
        System.out.println(e);
        }
    }
}

Don't trust Eclipse with where it says the file is. Go out to the actual filesystem with Windows Explorer or equivalent and check.

Based on your edit, I think we need to see your import statements as well.

DecimalFormat df = new DecimalFormat("###.##");
double total = Double.valueOf(val);

Generated Column is one of the good approach for MySql version which is 5.7.6 and above.

There are two kinds of Generated Columns:

• Virtual (default) - column will be calculated on the fly when a record is read from a table
• Stored - column will be calculated when a new record is written/updated in the table

Both types can have NOT NULL restrictions, but only a stored Generated Column can be a part of an index.

For current case, we are going to use stored generated column. To implement I have considered that both of the values required for calculation are present in table

CREATE TABLE order_details (price DOUBLE, quantity INT, amount DOUBLE AS (price * quantity));

INSERT INTO order_details (price, quantity) VALUES(100,1),(300,4),(60,8);

amount will automatically pop up in table and you can access it directly, also please note that whenever you will update any of the columns, amount will also get updated.

DECLARE
error_flag  BOOLEAN := false;
BEGIN

error_flag := true;
--error_flag := 13;--expression is of wrong type

  IF error_flag THEN 

UPDATE table_a SET id= 8 WHERE id = 1;

END IF;
END;

This answer will work to get just the text for any HTML element.

This first parameter "node" is the element to get the text from. The second parameter is optional and if true will add a space between the text within elements if no space would otherwise exist there.

function getTextFromNode(node, addSpaces) {
    var i, result, text, child;
    result = '';
    for (i = 0; i < node.childNodes.length; i++) {
        child = node.childNodes[i];
        text = null;
        if (child.nodeType === 1) {
            text = getTextFromNode(child, addSpaces);
        } else if (child.nodeType === 3) {
            text = child.nodeValue;
        }
        if (text) {
            if (addSpaces && /\S$/.test(result) && /^\S/.test(text)) text = ' ' + text;
            result += text;
        }
    }
    return result;
}

I know there isn't any need to add a plugin for this.

But this can be useful if you are doing so many things with numbers. So checkout this plugin at least for a knowledge point of view.

The rest of karim79's answer is super cool.

If you're using Radiant CMS, simply add

(Kudos to Aaron's and nathanvda's responses.)

Non Blocking

If you are on linux (as windows does not support calling select on files) you can use the subprocess module along with the select module.

import time
import subprocess
import select

f = subprocess.Popen(['tail','-F',filename],\
        stdout=subprocess.PIPE,stderr=subprocess.PIPE)
p = select.poll()
p.register(f.stdout)

while True:
    if p.poll(1):
        print f.stdout.readline()
    time.sleep(1)

This polls the output pipe for new data and prints it when it is available. Normally the time.sleep(1) and print f.stdout.readline() would be replaced with useful code.

Blocking

You can use the subprocess module without the extra select module calls.

import subprocess
f = subprocess.Popen(['tail','-F',filename],\
        stdout=subprocess.PIPE,stderr=subprocess.PIPE)
while True:
    line = f.stdout.readline()
    print line

This will also print new lines as they are added, but it will block until the tail program is closed, probably with f.kill().

I think it is worth mentioning that you don't generally need to use the whole agent string, unless perhaps you find a reason where you need to tailor the website to a specific model.

You can check for iPhone, iPad and iPod in the agent string and cover all your bases.

if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)) || (navigator.userAgent.match(/iPad/i))) {
    appleMobileDevice = true;
}
else {
    appleMobileDevice = false;
}

After looking through all the different methods posted here, I didn't see anyone utilize TRUE/FALSE to select and unselect data. So I thought I would share a method utilizing that technique.

n = nrow(dataset)
split = sample(c(TRUE, FALSE), n, replace=TRUE, prob=c(0.75, 0.25))

training = dataset[split, ]
testing = dataset[!split, ]

Explanation

There are multiple ways of selecting data from R, most commonly people use positive/negative indices to select/unselect respectively. However, the same functionalities can be achieved by using TRUE/FALSE to select/unselect.

Consider the following example.

# let's explore ways to select every other element
data = c(1, 2, 3, 4, 5)


# using positive indices to select wanted elements
data[c(1, 3, 5)]
[1] 1 3 5

# using negative indices to remove unwanted elements
data[c(-2, -4)]
[1] 1 3 5

# using booleans to select wanted elements
data[c(TRUE, FALSE, TRUE, FALSE, TRUE)]
[1] 1 3 5

# R recycles the TRUE/FALSE vector if it is not the correct dimension
data[c(TRUE, FALSE)]
[1] 1 3 5

There is no direct way - see http://groups.google.com/group/android-platform/browse_thread/thread/1728f26f2334c060/5e4910f0d9eb898a where Dianne Hackborn from the Android team has replied. However, you can detect it indirectly by checking if the window size changed in #onMeasure. See How to check visibility of software keyboard in Android?.

The key to the whole problem is here:

if (-1 == index) {
    throw ADP.IndexOutOfRange(fieldName);
}

If the referenced three lines (currently lines 72, 73, and 74) are taken out, then you can easily check for -1 in order to determine if the column doesn't exist.

The only way around this while ensuring native performance is to use a Reflection based implementation, like the following:

Usings:

using System;
using System.Data;
using System.Reflection;
using System.Data.SqlClient;
using System.Linq;
using System.Web.Compilation; // I'm not sure what the .NET Core equivalent to BuildManager.cs

The Reflection based extension method:

/// Gets the column ordinal, given the name of the column.
/// </summary>
/// <param name="reader"></param>
/// <param name="name">The name of the column.</param>
/// <returns> The zero-based column ordinal. -1 if the column does not exist.</returns>
public static int GetOrdinalSoft(this SqlDataReader reader, string name)
{
    try
    {
        // Note that "Statistics" will not be accounted for in this implemenation
        // If you have SqlConnection.StatisticsEnabled set to true (the default is false), you probably don't want to use this method
        // All of the following logic is inspired by the actual implementation of the framework:
        // https://referencesource.microsoft.com/#System.Data/fx/src/data/System/Data/SqlClient/SqlDataReader.cs,d66096b6f57cac74
        if (name == null)
            throw new ArgumentNullException("fieldName");

        Type sqlDataReaderType = typeof(SqlDataReader);
        object fieldNameLookup = sqlDataReaderType.GetField("_fieldNameLookup", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(reader);
        Type fieldNameLookupType;
        if (fieldNameLookup == null)
        {
            MethodInfo checkMetaDataIsReady = sqlDataReaderType.GetRuntimeMethods().First(x => x.Name == "CheckMetaDataIsReady" && x.GetParameters().Length == 0);
            checkMetaDataIsReady.Invoke(reader, null);
            fieldNameLookupType = BuildManager.GetType("System.Data.ProviderBase.FieldNameLookup", true, false);
            ConstructorInfo ctor = fieldNameLookupType.GetConstructor(new[] { typeof(SqlDataReader), typeof(int) });
            fieldNameLookup = ctor.Invoke(new object[] { reader, sqlDataReaderType.GetField("_defaultLCID", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(reader) });
        }
        else
            fieldNameLookupType = fieldNameLookup.GetType();

        MethodInfo indexOf = fieldNameLookupType.GetMethod("IndexOf", BindingFlags.Public | BindingFlags.Instance, null, new Type[] { typeof(string) }, null);

        return (int)indexOf.Invoke(fieldNameLookup, new object[] { name });
    }
    catch
    {
        // .NET Implemenation might have changed, revert back to the classic solution.
        if (reader.FieldCount > 11) // Performance observation by b_levitt
        {
            try
            {
                return reader.GetOrdinal(name);
            }
            catch
            {
                return -1;
            }
        }
        else
        {
            var exists = Enumerable.Range(0, reader.FieldCount).Any(i => string.Equals(reader.GetName(i), name, StringComparison.OrdinalIgnoreCase));

I think that the best solution for drawing text in OpenGL is texture fonts, I work with them for a long time. They are flexible, fast and nice looking (with some rear exceptions). I use special program for converting font files (.ttf for example) to texture, which is saved to file of some internal "font" format (I've developed format and program based on http://content.gpwiki.org/index.php/OpenGL:Tutorials:Font_System though my version went rather far from the original supporting Unicode and so on). When starting the main app, fonts are loaded from this "internal" format. Look link above for more information.

With such approach the main app doesn't use any special libraries like FreeType, which is undesirable for me also. Text is being drawn using standard OpenGL functions.

Suppose you have this scenario where you stash your changes in order to pull from origin. Possibly because your local changes are just debug: true in some settings file. Now you pull and someone has introduced a new setting there, creating a conflict.

git status says:

# On branch master
# Unmerged paths:
#   (use "git reset HEAD <file>..." to unstage)
#   (use "git add/rm <file>..." as appropriate to mark resolution)
#
#   both modified:      src/js/globals.tpl.js
no changes added to commit (use "git add" and/or "git commit -a")

Okay. I decided to go with what Git suggested: I resolved the conflict and committed:

vim src/js/globals.tpl.js
# type type type …
git commit -a -m WIP   # (short for "work in progress")

Now my working copy is in the state I want, but I have created a commit that I don't want to have. How do I get rid of that commit without modifying my working copy? Wait, there's a popular command for that!

git reset HEAD^

My working copy has not been changed, but the WIP commit is gone. That's exactly what I wanted! (Note that I'm not using --soft here, because if there are auto-merged files in your stash, they are auto-staged and thus you'd end up with these files being staged again after reset.)

But there's one more thing left: The man page for git stash pop reminds us that "Applying the state can fail with conflicts; in this case, it is not removed from the stash list. You need to resolve the conflicts by hand and call git stash drop manually afterwards." So that's exactly what we do now:

git stash drop

And done.

plt.errorbar can be used to plot x, y, error data (as opposed to the usual plt.plot)

import matplotlib.pyplot as plt
import numpy as np

x = np.array([1, 2, 3, 4, 5])
y = np.power(x, 2) # Effectively y = x**2
e = np.array([1.5, 2.6, 3.7, 4.6, 5.5])

plt.errorbar(x, y, e, linestyle='None', marker='^')

plt.show()

plt.errorbar accepts the same arguments as plt.plot with additional yerr and xerr which default to None (i.e. if you leave them blank it will act as plt.plot).

According to W3Schools.com,

The center element was deprecated in HTML 4.01, and is not supported in XHTML 1.0 Strict DTD.

The HTML 4.01 spec gives this reason for deprecating the tag:

The CENTER element is exactly equivalent to specifying the DIV element with the align attribute set to "center".

You could ignore that file with a file in your project base folder:

.gitignore

public/images/*

Then pull the changes and then remove that line from your gitignore file.

On Chrome this has proven to work well for me.

I recommend using:

#!/bin/bash

It's not 100% portable (some systems place bash in a location other than /bin), but the fact that a lot of existing scripts use #!/bin/bash pressures various operating systems to make /bin/bash at least a symlink to the main location.

The alternative of:

#!/usr/bin/env bash

has been suggested -- but there's no guarantee that the env command is in /usr/bin (and I've used systems where it isn't). Furthermore, this form will use the first instance of bash in the current users $PATH, which might not be a suitable version of the bash shell.

(But /usr/bin/env should work on any reasonably modern system, either because env is in /usr/bin or because the system does something to make it work. The system I referred to above was SunOS 4, which I probably haven't used in about 25 years.)

If you need a script to run on a system that doesn't have /bin/bash, you can modify the script to point to the correct location (that's admittedly inconvenient).

I've discussed the tradeoffs in greater depth in my answer to this question.

A somewhat obscure update: One system I use, Termux, a desktop-Linux-like layer that runs under Android, doesn't have /bin/bash (bash is /data/data/com.termux/files/usr/bin/bash) -- but it has special handling to support #!/bin/bash.

All do not work for me on eloquent collections, laravel eloquent collections use the key from the items I think which causes merging issues, you need to get the first collection back as an array, put that into a fresh collection and then push the others into the new collection;

public function getFixturesAttribute()
{
    $fixtures = collect( $this->homeFixtures->all() );
    $this->awayFixtures->each( function( $fixture ) use ( $fixtures ) {
        $fixtures->push( $fixture );
    });

In case this might help someone, after installing the thread safe version of PHP 5.5.1, everything was working under apache for my dev sites, but I ran into the same "php5.dll is missing" problem installing Composer using the Composer-Setup.exe - or, as I soon discovered, just running something as simple as php -v from the command line. I made a copy of php5ts.dll and named it php5.dll and everything worked. I assume the Composer installer was specifically looking for "php5.dll" and I knew that the thread safe code would be run by the renamed .dll. I also assume something is wrong with my setup to screw up the command line functionality, but with everything working, I have more important issues to deal with than to try and find the problem.

For me, I had to add:

git config --global --unset http.proxy

Basically, you can run:

git config --global -l 

to get the list of all proxy defined, and then use "--unset" to disable them

ngModel usually use for input tags for bind a variable that we can change variable from controller and html page but ngBind use for display a variable in html page and we can change variable just from controller and html just show variable.

With JUnit 4.12 the following didn't work for me:

java -cp .:/usr/share/java/junit.jar org.junit.runner.JUnitCore [test class name]

Apparently, from JUnit 4.11 onwards you should also include hamcrest-core.jar in your classpath:

java -cp .:/usr/share/java/junit.jar:/usr/share/java/hamcrest-core.jar org.junit.runner.JUnitCore [test class name]

Just coming from another question. I'd like to mention Pintos... I remembered my OS course with Nachos and Pintos seems to be the same kind of thing that can run on x86.

gofrs/uuid is the replacement for satori/go.uuid, which is the most starred UUID package for Go. It supports UUID versions 1-5 and is RFC 4122 and DCE 1.1 compliant.

import "github.com/gofrs/uuid"

// Create a Version 4 UUID, panicking on error
u := uuid.Must(uuid.NewV4())

Unity is just an IoC "container". Google StructureMap and try it out instead. A bit easier to grok, I think, when the IoC stuff is new to you.

Basically, if you understand IoC then you understand that what you're doing is inverting the control for when an object gets created.

Without IoC:

public class MyClass
{
   IMyService _myService; 

   public MyClass()
   {
      _myService = new SomeConcreteService();    
   }
}

With IoC container:

public class MyClass
{
   IMyService _myService; 

   public MyClass(IMyService myService)
   {
      _myService = myService;    
   }
}

Without IoC, your class that relies on the IMyService has to new-up a concrete version of the service to use. And that is bad for a number of reasons (you've coupled your class to a specific concrete version of the IMyService, you can't unit test it easily, you can't change it easily, etc.)

With an IoC container you "configure" the container to resolve those dependencies for you. So with a constructor-based injection scheme, you just pass the interface to the IMyService dependency into the constructor. When you create the MyClass with your container, your container will resolve the IMyService dependency for you.

Using StructureMap, configuring the container looks like this:

StructureMapConfiguration.ForRequestedType<MyClass>().TheDefaultIsConcreteType<MyClass>();
StructureMapConfiguration.ForRequestedType<IMyService>().TheDefaultIsConcreteType<SomeConcreteService>();

So what you've done is told the container, "When someone requests the IMyService, give them a copy of the SomeConcreteService." And you've also specified that when someone asks for a MyClass, they get a concrete MyClass.

That's all an IoC container really does. They can do more, but that's the thrust of it - they resolve dependencies for you, so you don't have to (and you don't have to use the "new" keyword throughout your code).

Final step: when you create your MyClass, you would do this:

var myClass = ObjectFactory.GetInstance<MyClass>();

Hope that helps. Feel free to e-mail me.

in Bootstrap 5 you can do something like this:

<div class="py-2 my-1 text-center position-relative mx-2">
            <div class="position-absolute w-100 top-50 start-50 translate-middle" style="z-index: 2">
                <span class="d-inline-block bg-white px-2 text-muted">or</span>
            </div>
            <div class="position-absolute w-100 top-50 start-0 border-muted border-top"></div>
</div>

To generate graph in png format you need to Install following dependent packages

sudo apt-get install libpng-dev
sudo apt-get install libfreetype6-dev

Ubuntu https://apps.ubuntu.com/cat/applications/libpng12-0/ or using following command

sudo apt-get install libpng12-0

With Spring Boot its not necessary to have any config file like persistence.xml. You can configure with annotations Just configure your DB config for JPA in the

application.properties

spring.datasource.driverClassName=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@DB...
spring.datasource.username=username
spring.datasource.password=pass

spring.jpa.database-platform=org.hibernate.dialect....
spring.jpa.show-sql=true

Then you can use CrudRepository provided by Spring where you have standard CRUD transaction methods. There you can also implement your own SQL's like JPQL.

@Transactional
public interface ObjectRepository extends CrudRepository<Object, Long> {
...
}

And if you still need to use the Entity Manager you can create another class.

public class ObjectRepositoryImpl implements ObjectCustomMethods{

    @PersistenceContext
    private EntityManager em;

}

This should be in your pom.xml

A few years ago it was said that update() and digest() were legacy methods and the new streaming API approach was introduced. Now the docs say that either method can be used. For example:

var crypto    = require('crypto');
var text      = 'I love cupcakes';
var secret    = 'abcdeg'; //make this your secret!!
var algorithm = 'sha1';   //consider using sha256
var hash, hmac;

// Method 1 - Writing to a stream
hmac = crypto.createHmac(algorithm, secret);    
hmac.write(text); // write in to the stream
hmac.end();       // can't read from the stream until you call end()
hash = hmac.read().toString('hex');    // read out hmac digest
console.log("Method 1: ", hash);

// Method 2 - Using update and digest:
hmac = crypto.createHmac(algorithm, secret);
hmac.update(text);
hash = hmac.digest('hex');
console.log("Method 2: ", hash);

Tested on node v6.2.2 and v7.7.2

See https://nodejs.org/api/crypto.html#crypto_class_hmac. Gives more examples for using the streaming approach.

To resolve this, you should open up a terminal window and type this command:

sudo chown -R user ~/.composer (with user being your current user, in your case, kramer65)

After you have ran this command, you should have permission to run your composer global require command.

You may also need to remove the .composer file from the current directory, to do this open up a terminal window and type this command:

sudo rm -rf .composer

import datetime from datetime

now = datetime.now()

print "%0.2d:%0.2d:%0.2d" % (now.hour, now.minute, now.second)

You can do the same with day & month etc.

jQuery.i18n is a lightweight jQuery plugin for enabling internationalization in your web pages. It allows you to package custom resource strings in ‘.properties’ files, just like in Java Resource Bundles. It loads and parses resource bundles (.properties) based on provided language or language reported by browser.

to know more about this take a look at the How to internationalize your pages using JQuery?

This is what it works for me in Swift:

override func viewWillDisappear(_ animated: Bool) {
    if self.navigationController?.viewControllers.index(of: self) == nil {
        // back button pressed or back gesture performed
    }

    super.viewWillDisappear(animated)
}

Thanks all for your responses. I used HtmlRenderer external dll (library) to achieve the same and found below code for the same.

Here is the code for this

   Bitmap m_Bitmap = new Bitmap(400, 600);
   PointF point = new PointF(0, 0);
   SizeF maxSize = new System.Drawing.SizeF(500, 500);
   HtmlRenderer.HtmlRender.Render(Graphics.FromImage(m_Bitmap),
                                           "<html><body><p>This is some html code</p>"
                                           + "<p>This is another html line</p></body>",
                                            point, maxSize);

   m_Bitmap.Save(@"C:\Test.png", ImageFormat.Png);
}

For a string of length 1 you can simply perform isdigit() or isalpha()

If your string length is greater than 1, you can make a function something like..

def isinteger(a):
    try:
        int(a)
        return True
    except ValueError:
        return False

You shouldn't blindly trust everything posted on stackoverflow. The comment in Jens code is incorrect, the parameter doesn't control whether exceptions are thrown or not.

MSDN is very clear what that parameter controls, have you read it? http://msdn.microsoft.com/en-us/library/dd321703(v=vs.110).aspx

If throwOnFirstException is true, an exception will immediately propagate out of the call to Cancel, preventing the remaining callbacks and cancelable operations from being processed. If throwOnFirstException is false, this overload will aggregate any exceptions thrown into an AggregateException, such that one callback throwing an exception will not prevent other registered callbacks from being executed.

The variable name is also wrong because Cancel is called on CancellationTokenSource not the token itself and the source changes state of each token it manages.

You can use both PHP and javascript. Perform your php codes in the backend and redirect to a php page. On the php page you redirected to add the code below:

<?php if(condition_to_check_for){ ?>

    <script type="text/javascript">
       window.open('url_goes_here', '_blank');
    </script>

<?  } ?>

For Microsoft Azure, it's slightly different.

Azure has a special CORS setting that needs to be set. It's essentially the same thing behind the scenes, but simply setting the header joshuarh mentions will not work. The Azure documentation for enabling cross domain can be found here:

https://docs.microsoft.com/en-us/azure/app-service-api/app-service-api-cors-consume-javascript

I fiddled around with this for a few hours before realizing my hosting platform had this special setting.

In fact, seems like a bit complicated, is not.

get method as a parameter:

 function JS_method(_callBack) { 

           _callBack("called");  

        }

You can give as a parameter method:

    JS_method(function (d) {
           //Finally this will work.
           alert(d)
    });

The first is better. If you try to debug the second and look at the call stack you won't see where the original exception came from. There are tricks to keep the call-stack intact (try search, it's been answered before) if you really need to rethrow.

You can't combine a WHERE clause with a VALUES clause. You have two options as far as I am aware-

1. INSERT specifying values

   INSERT INTO Users(weight, desiredWeight) 
   VALUES (160,145)
   

2. INSERT using a SELECT statement

   INSERT INTO Users(weight, desiredWeight) 
   SELECT weight, desiredWeight 
   FROM AnotherTable 
   WHERE id = 1
   

The $files array will get all files in the directory which the specified extension

$directory = 'pathto/directory';
$files = array();
$allowed_ext = array( "xml", "png", "jpg", "jpeg", "txt", "doc", "xls","csv"); 
// Check if the directory exists or not
if (file_exists($directory) && is_dir($directory)) {
    // Get the files in the directory
    $scan_contents = scandir($directory);
    // Filter out the current (.) and parent (..) directories 
    $files_array = array_diff($scan_contents, array('.', '..'));
    // Get each files of our directory with line break
    foreach ($files_array as $file) {
        //Get the file path
        $file_path = "$directory/$file";
        // Get the file extension
        $file_ext = strtolower(pathinfo($file_path, PATHINFO_EXTENSION));        
        if (in_array($file_ext, $allowed_ext) ) {
            $files[] = $file_path;
        }
    }
} 
echo '<pre>$files:-';
print_r($files);
echo '</pre>';

Programs to monitor if a process on a system is running.

Script is stored in crontab and runs once every minute.

This works with if process is not running or process is running multiple times:

#! /bin/bash

case "$(pidof amadeus.x86 | wc -w)" in

0)  echo "Restarting Amadeus:     $(date)" >> /var/log/amadeus.txt
    /etc/amadeus/amadeus.x86 &
    ;;
1)  # all ok
    ;;
*)  echo "Removed double Amadeus: $(date)" >> /var/log/amadeus.txt
    kill $(pidof amadeus.x86 | awk '{print $1}')
    ;;
esac

0 If process is not found, restart it.
1 If process is found, all ok.
* If process running 2 or more, kill the last.

A simpler version. This just test if process is running, and if not restart it.

It just tests the exit flag $? from the pidof program. It will be 0 of process is running and 1 if not.

#!/bin/bash
pidof  amadeus.x86 >/dev/null
if [[ $? -ne 0 ]] ; then
        echo "Restarting Amadeus:     $(date)" >> /var/log/amadeus.txt
        /etc/amadeus/amadeus.x86 &
fi

And at last, a one liner

pidof amadeus.x86 >/dev/null ; [[ $? -ne 0 ]] && echo "Restarting Amadeus:     $(date)" >> /var/log/amadeus.txt && /etc/amadeus/amadeus.x86 &

You could also use to localStorage feature of HTML5 to store your test value and then access it at any other point in your website by using the localStorage.getItem() method. To see how this works you should look at the w3schools explanation or the explanation from the Opera Developer website. Hope this helps.

Some of the solutions described here did not work for me. Others did, however they produced warnings on runtime and javadoc was still not linked. After some experimenting, I managed to solve this. The steps are:

1. Install the Google Play Services as recommended on Android Developers.

2. Set up your project as recommended on Android Developers.

3. If you followed 1. and 2., you should see two projects in your workspace: your project and google-play-services_lib project. Copy the docs folder which contains the javadoc from <android-sdk>/extras/google/google_play_services/ to libs folder of your project.

4. Copy google-play-services.jar from <android-sdk>/extras/google/google_play_services/libproject/google-play-services_lib/libs to 'libs' folder of your project.

5. In google-play-services_lib project, edit libs/google-play-services.jar.properties . The <path> in doc=<path> should point to the subfolder reference of the folder docs, which you created in step 3.

6. In Eclipse, do Project > Clean. Done, javadoc is now linked.

publicIHttpActionResultPost(Productproduct) {  
    if (ModelState.IsValid) {  
        //Dosomethingwiththeproduct(notshown).  
        returnOk();  
    } else {  
        returnBadRequest();  
    }  
}

OR

public HttpResponseMessage Post(Product product)
        {
            if (ModelState.IsValid)
            {
                // Do something with the product (not shown).

                return new HttpResponseMessage(HttpStatusCode.OK);
            }
            else
            {
                return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);
            }
        }

According to mzabriskie on GitHub:

Overall they are very similar. Some benefits of axios:

• Transformers: allow performing transforms on data before a request is made or after a response is received

• Interceptors: allow you to alter the request or response entirely (headers as well). also, perform async operations before a request is made or before Promise settles

• Built-in XSRF protection

please check Browser Support Axios

I think you should use axios.

A simpler one would be

list(dictionary.items())  # list of (key, value) tuples
list(zip(dictionary.values(), dictionary.keys()))  # list of (key, value) tuples

Lodash _.isEqual allows you to do that:

var_x000D_
remoteJSON = {"allowExternalMembers": "false", "whoCanJoin": "CAN_REQUEST_TO_JOIN"},_x000D_
    localJSON = {"whoCanJoin": "CAN_REQUEST_TO_JOIN", "allowExternalMembers": "false"};_x000D_
    _x000D_
console.log( _.isEqual(remoteJSON, localJSON) );

<script src="https://cdn.jsdelivr.net/npm/[email protected]/lodash.min.js"></script>

I was receiving the same error message, and my issue was that I was not in the correct directory when running the command make install. When I changed to the directory that had my makefile it worked.

So possibly you aren't in the right directory.

You can try this:

HTML

<table>
    <tr>
        <td class="shrink">element1</td>
        <td class="shrink">data</td>
        <td class="shrink">junk here</td>
        <td class="expand">last column</td>
    </tr>
    <tr>
        <td class="shrink">elem</td>
        <td class="shrink">more data</td>
        <td class="shrink">other stuff</td>
        <td class="expand">again, last column</td>
    </tr>
    <tr>
        <td class="shrink">more</td>
        <td class="shrink">of </td>
        <td class="shrink">these</td>
        <td class="expand">rows</td>
    </tr>
</table>

CSS

table {
    border: 1px solid green;
    border-collapse: collapse;
    width:100%;
}

table td {
    border: 1px solid green;
}

table td.shrink {
    white-space:nowrap
}
table td.expand {
    width: 99%
}

First, you must know that you will never be able to get the source code of a page that is not on the same domain as your page in javascript. (See http://en.wikipedia.org/wiki/Same_origin_policy).

In PHP, this is how you do it:

file_get_contents($theUrl);

In javascript, there is three ways :

Firstly, by XMLHttpRequest : http://jsfiddle.net/635YY/1/

var url="../635YY",xmlhttp;//Remember, same domain
if("XMLHttpRequest" in window)xmlhttp=new XMLHttpRequest();
if("ActiveXObject" in window)xmlhttp=new ActiveXObject("Msxml2.XMLHTTP");
xmlhttp.open('GET',url,true);
xmlhttp.onreadystatechange=function()
{
    if(xmlhttp.readyState==4)alert(xmlhttp.responseText);
};
xmlhttp.send(null);

Secondly, by iFrames : http://jsfiddle.net/XYjuX/1/

var url="../XYjuX";//Remember, same domain
var iframe=document.createElement("iframe");
iframe.onload=function()
{
    alert(iframe.contentWindow.document.body.innerHTML);
}
iframe.src=url;
iframe.style.display="none";
document.body.appendChild(iframe);

Thirdly, by jQuery : [http://jsfiddle.net/edggD/2/

$.get('../edggD',function(data)//Remember, same domain
{
    alert(data);
});

Related to the response using ClientHttpInterceptor, I found a way of keeping the whole response without Buffering factories. Just store the response body input stream inside byte array using some utils method that will copy that array from body, but important, surround this method with try catch because it will break if response is empty (that is the cause of Resource Access Exception) and in catch just create empty byte array, and than just create anonymous inner class of ClientHttpResponse using that array and other parameters from the original response. Than you can return that new ClientHttpResponse object to the rest template execution chain and you can log response using body byte array that is previously stored. That way you will avoid consuming InputStream in the actual response and you can use Rest Template response as it is. Note, this may be dangerous if your's response is too big

Thanks Yannis, your solution worked for me and here I'm sharing same solution for multiple keywords with order and limit.

Adding a 100% to the width and height attributes of its iframe has always worked for me. For example

I recognize that the answer works and has been accepted but there is a much cleaner way to write that query. Tested on mysql and postgres.

SELECT wpoi.order_id As No_Commande
FROM  wp_woocommerce_order_items AS wpoi
LEFT JOIN wp_postmeta AS wpp ON wpoi.order_id = wpp.post_id 
                            AND wpp.meta_key = '_shipping_first_name'
WHERE  wpoi.order_id =2198 

you can determine the last element with this code :

for i,element in enumerate(list):
    if (i==len(list)-1):
        print("last element is" + element)

Please do not take this as an answer to the question. It is not, but an advice related to exploiting the difference of int and float. I would have put this under a comment except that the answer box allows me to format this comment.

This feature has been used in every respectable programming language since the days of fortran (or earlier) - I must confess I was once a Fortran and Cobol punch card programmer.

As an example, integer division of 10/3 yields integer value 3 since an integer has no facility to hold fractional residual .3333.. .

One of the ways we (old time ancient programmers) had been using this feature is loop control.

Let's say we wish to print an array of 1000 strings, but we wish to insert a line break after every 15th string, to insert some prettyfying chars at the end of the line and at the beginning of the next line. We exploit this, given that integer k is the position of a string in that array.

int(k/15)*15 == k

is true only when k is divisible by 15, an occurrence at a frequency of every 15th cell. Which is akin to what my friend said about his grandfather's dead watch being accurate twice a day.

int(1/15) = 0 -> int(1/15)*15 = 0
int(2/15) = 0 -> int(2/15)*15 = 0
...
int(14/15) = 0 -> int(14/15)*15 = 0
int(15/15) = 1 -> int(15/15)*15 = 15

int(16/15) = 1 -> int(16/15)*15 = 15
int(17/15) = 1 -> int(17/15)*15 = 15
...
int(29/15) = 1 -> int(29/15)*15 = 15
int(30/15) = 2 -> int(30/15)*15 = 30

Therefore, the loop,

leftPrettyfy();
for(int k=0; k<sa.length; k++){
  print(sa[k]);
  int z = k + 1;
  if ((z/15)*15 == z){
    rightPrettyfy();
    leftPrettyfy();
  }
}

By varying k in a fanciful way in the loop, we could print a triangular printout

1
2  3
4  5  6
7  8  9  10
11 12 13 14 15

That is to demonstrate that, if you consider this a bug, this "bug" is a useful feature that we would not want to be removed from any of the various languages that we have used thus far.

window load will wait for all resources to be loaded.

document ready waits for the document to be initialized.

unload well, waits till the document is being unloaded.

the order is: document ready, window load, ... ... ... ... window unload.

always use document ready unless you need to wait for your images to load.

shorthand for document ready:

$(function(){
    // yay!
});

In my case:

• Using built in WXGA720 to simulate 720p device, always got this error
• Manually set AVD resolution to 720 x 1280, works for me

hope it helps~

On Yosemite, if the pid file is blocking Postgres from starting and you have a launchctl daemon trying (and failing) to load the database daemons, then you'll need to unload the plist file:

$ launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

Then remove the pid file

$ rm /usr/local/var/postgres/postmaster.pid

Then reload the launchctl daemon

$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

As already noted in a previous answer, this situation may arise due to line-ending problems (CR/LF vs. LF). I solved this problem (under Git version 2.22.0) with this command:

git add --renormalize .

According to the manual:

       --renormalize
           Apply the "clean" process freshly to all tracked files to
           forcibly add them again to the index. This is useful after
           changing core.autocrlf configuration or the text attribute in
           order to correct files added with wrong CRLF/LF line endings.
           This option implies -u.

Directory listing varies greatly according to the OS/platform under consideration. This is because, various Operating systems using their own internal system calls to achieve this.

A solution to this problem would be to look for a library which masks this problem and portable. Unfortunately, there is no solution that works on all platforms flawlessly.

On POSIX compatible systems, you could use the library to achieve this using the code posted by Clayton (which is referenced originally from the Advanced Programming under UNIX book by W. Richard Stevens). this solution will work under *NIX systems and would also work on Windows if you have Cygwin installed.

Alternatively, you could write a code to detect the underlying OS and then call the appropriate directory listing function which would hold the 'proper' way of listing the directory structure under that OS.

We need to add host security certificate to php.ini file. For local developement enviroment we can add cacert.pem in your local php.ini.

do phpinfo(); and file your php.ini path open and add uncomment ;curl.capath

curl.capath=path_of_your_cacert.pem

For Ubuntu 18.04 and php7.3, install php7.3-xml sudo apt-get install php7.3-xml

this will installl the required simplexml

You should always avoid using List<T> as a parameter. Not only because this pattern reduces the opportunities of the caller to store the data in a different kind of collection, but also the caller has to convert the data into a List first.

Converting an IEnumerable into a List costs O(n) complexity which is absolutely unneccessary. And it also creates a new object.

TL;DR you should always use a proper interface like IEnumerable or IQueryable based on what do you want to do with your collection. ;)

In your case:

public void foo(IEnumerable<DateTime> dateTimes)
{
}

i have solve this problem several times using the same steps :

1- Close Eclipse.

2- Restart your phone.

3- End adb.exe process in Task Manager (Windows). In Mac, force close in Activity Monitor.

4- Issue kill and start command in \platform-tools\

C:\sdk\platform-tools>adb kill-server

C:\sdk\platform-tools>adb start-server

5- If it says something like 'started successfully', you are good.

but now it's doesn't work cause i have an anti-virus called "Baidu", this program have run "Baidu ADB server", finally i turn this process off and retry above steps it's work properly.

Here is a good example -

ul li{
    list-style-type: disc;
    list-style-position: inside;
    padding: 10px 0 10px 20px;
    text-indent: -1em;
}

Working Demo: http://jsfiddle.net/d9VNk/

I can't really say why you get the "No grammar constraints..." warning, but I can provoke it in Eclipse by completely removing the DOCTYPE declaration. When I put the declaration back and validate again, I get this error message:

The content of element type "template" must match "(description+,variation?,variation-field?,allow-multiple-variation?,class-pattern?,getter-setter?,allowed-file-extensions?,template-body+).

And that is correct, I believe (the "number-required-classes" element is not allowed).

IMHO, it is more efficient to drop the table and re-create it. And yes, you can use "IF EXISTS" in this case.

Something like this should do the trick (However, read after the snippet for more info)

CREATE PROCEDURE GetFilteredData()
BEGIN
  DECLARE bDone INT;

  DECLARE var1 CHAR(16);    -- or approriate type
  DECLARE Var2 INT;
  DECLARE Var3 VARCHAR(50);

  DECLARE curs CURSOR FOR  SELECT something FROM somewhere WHERE some stuff;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET bDone = 1;

  DROP TEMPORARY TABLE IF EXISTS tblResults;
  CREATE TEMPORARY TABLE IF NOT EXISTS tblResults  (
    --Fld1 type,
    --Fld2 type,
    --...
  );

  OPEN curs;

  SET bDone = 0;
  REPEAT
    FETCH curs INTO var1,, b;

    IF whatever_filtering_desired
       -- here for whatever_transformation_may_be_desired
       INSERT INTO tblResults VALUES (var1, var2, var3 ...);
    END IF;
  UNTIL bDone END REPEAT;

  CLOSE curs;
  SELECT * FROM tblResults;
END

A few things to consider...

Concerning the snippet above:

• may want to pass part of the query to the Stored Procedure, maybe particularly the search criteria, to make it more generic.
• If this method is to be called by multiple sessions etc. may want to pass a Session ID of sort to create a unique temporary table name (actually unnecessary concern since different sessions do not share the same temporary file namespace; see comment by Gruber, below)
• A few parts such as the variable declarations, the SELECT query etc. need to be properly specified

More generally: trying to avoid needing a cursor.

I purposely named the cursor variable curs[e], because cursors are a mixed blessing. They can help us implement complicated business rules that may be difficult to express in the declarative form of SQL, but it then brings us to use the procedural (imperative) form of SQL, which is a general feature of SQL which is neither very friendly/expressive, programming-wise, and often less efficient performance-wise.

Maybe you can look into expressing the transformation and filtering desired in the context of a "plain" (declarative) SQL query.

You can use "netstat" to check whether a port is available or not.

Use the netstat -anp | find "port number" command to find whether a port is occupied by an another process or not. If it is occupied by an another process, it will show the process id of that process.

You have to put : before port number to get the actual output

Ex netstat -anp | find ":8080"

In a php section before the HTML section, use sprinf() to create a constant string from the variables:

$mystuff = sprinf("My name is %s and my mother's name is %s","Suzy","Caroline");

Then in the HTML section you can do whatever you like, such as:

<p>$mystuff</p> 

The Answer above:

sed -i '/TEXT_TO_BE_REPLACED/c\This line is removed by the admin.' /tmp/foo

Works fine if the replacement string/line is not a variable.

The issue is that on Redhat 5 the \ after the c escapes the $. A double \\ did not work either (at least on Redhat 5).

Through hit and trial, I discovered that the \ after the c is redundant if your replacement string/line is only a single line. So I did not use \ after the c, used a variable as a single replacement line and it was joy.

The code would look something like:

sed -i "/TEXT_TO_BE_REPLACED/c $REPLACEMENT_TEXT_STRING" /tmp/foo

Note the use of double quotes instead of single quotes.

You could do:

$posted = preg_replace('/ By.*/', '', $posted);
echo $posted;

Try this, this works fine for me

from record in context.Organization where record.Hierarchy.Contains(12) select record;

while(something.hasnext())
do something...
   if(contains something to process){
      do something...
      break;
   }
}

Just use the break statement;

For eg:this just prints "Breaking..."

while (true) {
     if (true) {
         System.out.println("Breaking...");
         break;
     }
     System.out.println("Did this print?");
}

Use:

SELECT * 
FROM [Janus999DB].[dbo].[tblCustomerPlay] 
WHERE DatePlayed <  GetDate() 
AND DatePlayed > dateadd(minute, -30, GetDate())

If you want to use the toDF method, you have to convert your RDD of Array[String] into a RDD of a case class. For example, you have to do:

case class Test(id:String,filed2:String)
val myFile = sc.textFile("file.txt")
val df= myFile.map( x => x.split(";") ).map( x=> Test(x(0),x(1)) ).toDF()

The URL syntax is the same regardless of the platform in use

String url = "https://www.google.com/maps/search/?api=1&query=" + latitude + ","+ 
longitude;

In Android or iOS the URL launches Google Maps in the Maps app, If the Google Maps app is not installed, the URL launches Google Maps in a browser and performs the requested action.

On any other device, the URL launches Google Maps in a browser and performs the requested action.

here's the link for official documentation https://developers.google.com/maps/documentation/urls/guide

let dateString = "1970-01-01T13:30:00.000Z"
let formatter = DateFormatter()

formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
let date = formatter.date(from: String(dateString.dropLast(5)))!
formatter.dateFormat = "hh.mma"
print(formatter.string(from: date))

if You notice I have set .dateFormat = "hh.mma"by this you will get time only. Result:01.30PM

I just had this happen to me on a 'plain' CSV file. Some people might call it an invalid formatted file. No escape characters, no double quotes and delimiter was a semicolon.

A sample line from this file would look like this:

First cell; Second " Cell with one double quote and leading space;'Partially quoted' cell;Last cell

the single quote in the second cell would throw the parser off its rails. What worked was:

csv.reader(inputfile, delimiter=';', doublequote='False', quotechar='', quoting=csv.QUOTE_NONE)

As mentioned before, you can do this:

 WebView  host = (WebView)this.findViewById(R.id.webView);
 String url = "<yoururladdress>";

 Map <String, String> extraHeaders = new HashMap<String, String>();
 extraHeaders.put("Authorization","Bearer"); 
 host.loadUrl(url,extraHeaders);

I tested this and on with a MVC Controller that I extended the Authorize Attribute to inspect the header and the header is there.

Not a regexp expert, but I think you could use a negative lookahead from the start, e.g. ^(?!foo).*$ shouldn't match anything starting with foo.

if you have this already and use jquery this will be your answer:

$($(this)[0].selectedOptions[0]).text()

Take one example - you have a table with huge data per row. That means every instance of the object is Big.

If you use B tree here then most of the time is spent scanning the pages with data - which is of no use. In databases that is the reason of using B+ Trees to avoid scanning object data.

B+ Trees separate keys from data.

But if your data size is less then you can store them with key which is what B tree does.

If you have the PL/PGSQL procedural language installed you can use the following to remove everything without a shell/Perl external script.

DROP FUNCTION IF EXISTS remove_all();

CREATE FUNCTION remove_all() RETURNS void AS $$
DECLARE
    rec RECORD;
    cmd text;
BEGIN
    cmd := '';

    FOR rec IN SELECT
            'DROP SEQUENCE ' || quote_ident(n.nspname) || '.'
                || quote_ident(c.relname) || ' CASCADE;' AS name
        FROM
            pg_catalog.pg_class AS c
        LEFT JOIN
            pg_catalog.pg_namespace AS n

            n.oid = c.relnamespace
        WHERE
            relkind = 'S' AND
            n.nspname NOT IN ('pg_catalog', 'pg_toast') AND
            pg_catalog.pg_table_is_visible(c.oid)
    LOOP
        cmd := cmd || rec.name;

Rather than type this in at the "psql" prompt I would suggest you copy it to a file and then pass the file as input to psql using the "--file" or "-f" options:

psql -f clean_all_pg.sql

Credit where credit is due: I wrote the function, but think the queries (or the first one at least) came from someone on one of the pgsql mailing lists years ago. Don't remember exactly when or which one.

Solved this by adding following

RewriteCond %{ENV:REDIRECT_STATUS} 200 [OR]
 RewriteCond %{REQUEST_FILENAME} -f [OR]
 RewriteCond %{REQUEST_FILENAME} -d
 RewriteRule ^ - [L]

Instead use use appendTo. append or appendTo returns a jQuery object so you don't have to wrap it inside $().

var holdyDiv = $('<div />').appendTo('body');
holdyDiv.attr('id', 'holdy');

.appendTo() reference: http://api.jquery.com/appendTo/

Alernatively you can try this also.

$('<div />', { id: 'holdy' }).appendTo('body');
               ^
             (Here you can specify any attribute/value pair you want)

You could also do:

 for option in options:
      if option == options[selected_index]:
           #print
      else:
           #print

Although you'd run into issues if there are duplicate options.

try this..

SELECT Name
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%CreatedDate%'
GO

or you can generate a scripts of all procedures and search from there.

xargs on MacOS doesn't have -d option, so this solution uses -0 instead.

Get ls to output one file per line, then translate newlines into nulls and tell xargs to use nulls as the delimiter:

ls -1 *mp3 | tr "\n" "\0" | xargs -0 mplayer

var inputs = document.querySelectorAll("input[type=text]") ||
(function() {
    var ret=[], elems = document.getElementsByTagName('input'), i=0,l=elems.length;
    for (;i<l;i++) {
        if (elems[i].type.toLowerCase() === "text") {
            ret.push(elems[i]);
        }
    }

    return ret;
}());

Use row_count - your_desired_offset

So if we had 10 rows and want to offset 3

 10 - 3 = 7

Now the query delete from table where this = that order asc limit 7 keeps the last 3, and order desc to keep the first 3:

$row_count - $offset = $limit

Delete from table where entry = criteria order by ts asc limit $limit

Basically, you only need junit.jar on the classpath - and here's a quick way to do it:

1. Make sure you have a source folder (e.g. test) marked as a Test Root.

2. Create a test, for example like this:

   public class MyClassTest {
       @Test
       public void testSomething() {
   
       }
   }
   

3. Since you haven't configured junit.jar (yet), the @Test annotation will be marked as an error (red), hit f2 to navigate to it.

4. Hit alt-enter and choose Add junit.jar to the classpath

There, you're done! Right-click on your test and choose Run 'MyClassTest' to run it and see the test results.

Maven Note: Altervatively, if you're using maven, at step 4 you can instead choose the option Add Maven Dependency..., go to the Search for artifact pane, type junit and take whichever version (e.g. 4.8 or 4.9).

Since Java 1.5, String.format() can be used to left/right pad a given string.

public static String padRight(String s, int n) {
     return String.format("%-" + n + "s", s);  
}

public static String padLeft(String s, int n) {
    return String.format("%" + n + "s", s);  
}

...

public static void main(String args[]) throws Exception {
 System.out.println(padRight("Howto", 20) + "*");
 System.out.println(padLeft("Howto", 20) + "*");
}

And the output is:

Howto               *
               Howto*

Visual Studio with PTVS could be an option for you: http://www.hanselman.com/blog/OneOfMicrosoftsBestKeptSecretsPythonToolsForVisualStudioPTVS.aspx

Actually, this is a mixture of C and C++ syntax.

You should either use pure C arrays, which cannot be of references, since reference are part of C++ only. Or you go the C++ way and use the std::vector or std::array class for your purpose.

As for the edited part: Even though the struct is an element from C, you define a constructor and operator functions, which make it a C++ class. Consequently, your struct would not compile in pure C!

This is an iterable function without yield. It make use of the iter function and a closure which keeps it's state in a mutable (list) in the enclosing scope for python 2.

def count(low, high):
    counter = [0]
    def tmp():
        val = low + counter[0]
        if val < high:
            counter[0] += 1
            return val
        return None
    return iter(tmp, None)

For Python 3, closure state is kept in an immutable in the enclosing scope and nonlocal is used in local scope to update the state variable.

def count(low, high):
    counter = 0
    def tmp():
        nonlocal counter
        val = low + counter
        if val < high:
            counter += 1
            return val
        return None
    return iter(tmp, None)  

Test;

for i in count(1,10):
    print(i)

You can use the environment variable NUMBER_OF_PROCESSORS for the total number of processors:

echo %NUMBER_OF_PROCESSORS%

The plattform agnostic way would be 'sLineBreak': http://www.freepascal.org/docs-html/rtl/system/slinebreak.html

Write('Hello' + sLineBreak + 'World!');

In my case it was due to 'lower_case_table_names' parameter.

The error number 39 thrown out when I tried to drop the databases which consists upper case table names with lower_case_table_names parameter is enabled.

This is fixed by reverting back the lower case parameter changes to the previous state.

To copy remote-to-remote files you can use the synchronize module with 'delegate_to: source-server' keyword:

- hosts: serverB
  tasks:    
   - name: Copy Remote-To-Remote (from serverA to serverB)
     synchronize: src=/copy/from_serverA dest=/copy/to_serverB
     delegate_to: serverA

This playbook can run from your machineC.

From Java SE 6 HotSpot[tm] Virtual Machine Garbage Collection Tuning

the following

Excessive GC Time and OutOfMemoryError

The concurrent collector will throw an OutOfMemoryError if too much time is being spent in garbage collection: if more than 98% of the total time is spent in garbage collection and less than 2% of the heap is recovered, an OutOfMemoryError will be thrown. This feature is designed to prevent applications from running for an extended period of time while making little or no progress because the heap is too small. If necessary, this feature can be disabled by adding the option -XX:-UseGCOverheadLimit to the command line.

The policy is the same as that in the parallel collector, except that time spent performing concurrent collections is not counted toward the 98% time limit. In other words, only collections performed while the application is stopped count toward excessive GC time. Such collections are typically due to a concurrent mode failure or an explicit collection request (e.g., a call to System.gc()).

in conjunction with a passage further down

One of the most commonly encountered uses of explicit garbage collection occurs with RMIs distributed garbage collection (DGC). Applications using RMI refer to objects in other virtual machines. Garbage cannot be collected in these distributed applications without occasionally collection the local heap, so RMI forces full collections periodically. The frequency of these collections can be controlled with properties. For example,

java -Dsun.rmi.dgc.client.gcInterval=3600000

-Dsun.rmi.dgc.server.gcInterval=3600000 specifies explicit collection once per hour instead of the default rate of once per minute. However, this may also cause some objects to take much longer to be reclaimed. These properties can be set as high as Long.MAX_VALUE to make the time between explicit collections effectively infinite, if there is no desire for an upper bound on the timeliness of DGC activity.

Seems to imply that the evaluation period for determining the 98% is one minute long, but it might be configurable on Sun's JVM with the correct define.

Of course, other interpretations are possible.

I use grep as a naive solution.

$ git diff | grep -A2 -- '---'

an output example:

--- a/fileA.txt
+++ b/fileA.txt
@@ -0,0 +1,132 @@

Maybe you can see a colored output. It helps you to read outputs easily.

The below command will work fine for this approach:

find ./ -name "file_pattern_name"  -exec grep -r "pattern" {} \;

Java 8 introduces the Instant.ofEpochSecond utility method for creating an Instant from a Unix timestamp, this can then be converted into a ZonedDateTime and finally formatted, e.g.:

final DateTimeFormatter formatter = 
    DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

final long unixTime = 1372339860;
final String formattedDtm = Instant.ofEpochSecond(unixTime)
        .atZone(ZoneId.of("GMT-4"))
        .format(formatter);

System.out.println(formattedDtm);   // => '2013-06-27 09:31:00'

I thought this might be useful for people who are using Java 8.

If you try this:

#include<stdio.h>

void main()
{
 char name[]="siva";
 printf("name = %p\n", name);
 printf("&name[0] = %p\n", &name[0]);
 printf("name printed as %%s is %s\n",name);
 printf("*name = %c\n",*name);
 printf("name[0] = %c\n", name[0]);
}

Output is:

name = 0xbff5391b  
&name[0] = 0xbff5391b
name printed as %s is siva
*name = s
name[0] = s

So 'name' is actually a pointer to the array of characters in memory. If you try reading the first four bytes at 0xbff5391b, you will see 's', 'i', 'v' and 'a'

Location     Data
=========   ======

0xbff5391b    0x73  's'  ---> name[0]
0xbff5391c    0x69  'i'  ---> name[1]
0xbff5391d    0x76  'v'  ---> name[2]
0xbff5391e    0x61  'a'  ---> name[3]
0xbff5391f    0x00  '\0' ---> This is the NULL termination of the string

To print a character you need to pass the value of the character to printf. The value can be referenced as name[0] or *name (since for an array name = &name[0]).

To print a string you need to pass a pointer to the string to printf (in this case 'name' or '&name[0]').

Defining a specific version to upgrade helped me instead of only the upgrade command.

pip3 install larapy-installer==0.4.01 -U

It will show you the console

This is the code as 2017:

Facebook now takes all data from OG metatags.

Apart from the solutions already mentioned, you can also download jquery.min.js locally and then use it -

For downloading -

wget "https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"

manifest.json -

"content_scripts": [
   {
    "js": ["/path/to/jquery.min.js", ...]
   }
],

in html -

<script src="/path/to/jquery.min.js"></script>

Reference - https://developer.chrome.com/extensions/contentSecurityPolicy

Just set the SelectedPath property before calling ShowDialog.

fdbLocation.SelectedPath = myFolder;

You must specify the file to be downloaded (attachment) by the client in the http header:

Response.ContentType = "application/vnd.ms-excel"
Response.AppendHeader "content-disposition", "attachment: filename=excelTest.xls"

When you've written something that isn't allowed by the language standard (and therefore can't really be well-defined behaviour, which is reason enough to not do it) but happens to map to some kind of executable if fed naïvely to the compiling engine, then -fpermissive will do just that instead of stopping with this error message. In some cases, the program will then behave exactly as you originally intended, but you definitely shouldn't rely on it unless you have some very special reason not to use some other solution.

I created this function that allows to enter a string and returns a list of string trimmed by any character

 func Trim(input:String, character:Character)-> [String]
{
    var collection:[String] = [String]()
    var index  = 0
    var copy = input
    let iterable = input
    var trim = input.startIndex.advancedBy(index)

    for i in iterable.characters

    {
        if (i == character)
        {

            trim = input.startIndex.advancedBy(index)
            // apennding to the list
            collection.append(copy.substringToIndex(trim))

            //cut the input
            index += 1
            trim = input.startIndex.advancedBy(index)
            copy = copy.substringFromIndex(trim)

            index = 0
        }
        else
        {
            index += 1
        }
    }
    collection.append(copy)
    return collection

}

as didn't found a way to do this in swift (compiles and work perfectly in swift 2.0)

Many of these solutions didn't work for me. This did the trick though:-

$svgxml = preg_replace("/(*BSR_ANYCRLF)\R/",'',$svgxml);

Here is the reference:- PCRE and New Lines

I assume you have updated ADT with version 22 and R.java file is not getting generated.

If this is the case, then here is the solution:

Hope you know Android studio has gradle building tool. Same as in eclipse they have given new component in the Tools folder called Android SDK Build-tools that needs to be installed. Open the Android SDK Manager, select the newly added build tools, install it, restart the SDK Manager after the update.

I think this is the correct answer for csh.

xxx >/dev/stderr

Note most csh are really tcsh in modern environments:

rmockler> ls -latr /usr/bin/csh

lrwxrwxrwx 1 root root 9 2011-05-03 13:40 /usr/bin/csh -> /bin/tcsh

using a backtick embedded statement to portray this as follows:

echo "`echo 'standard out1'` `echo 'error out1' >/dev/stderr` `echo 'standard out2'`" | tee -a /tmp/test.txt ; cat /tmp/test.txt

if this works for you please bump up to 1. The other suggestions don't work for my csh environment.

Building up on Dmitri Pavlutin and joshua.paling answers, here's an extended version that extracts the base64 content (removes the metadata at the beginning) and also ensures padding is done correctly.

function getBase64(file) {
  return new Promise((resolve, reject) => {
    const reader = new FileReader();
    reader.readAsDataURL(file);
    reader.onload = () => {
      let encoded = reader.result.toString().replace(/^data:(.*,)?/, '');
      if ((encoded.length % 4) > 0) {
        encoded += '='.repeat(4 - (encoded.length % 4));
      }
      resolve(encoded);
    };
    reader.onerror = error => reject(error);
  });
}

You have to use the ReDim statement to dynamically size arrays.

Public Sub Test()
    Dim NumberOfZombies As Integer
    NumberOfZombies = 20000
    Dim Zombies() As New Zombie
    ReDim Zombies(NumberOfZombies)

End Sub

This can seem strange when you already know the size of your array, but there you go!

I want to just refresh the div, without refreshing the page ... Is this possible?

Yes, though it isn't going to be obvious that it does anything unless you change the contents of the div.

If you just want the graphical fade-in effect, simply remove the .html(data) call:

$("#panel").hide().fadeIn('fast');

Here is a demo you can mess around with: http://jsfiddle.net/ZPYUS/

It changes the contents of the div without making an ajax call to the server, and without refreshing the page. The content is hard coded, though. You can't do anything about that fact without contacting the server somehow: ajax, some sort of sub-page request, or some sort of page refresh.

html:

<div id="panel">test data</div>
<input id="changePanel" value="Change Panel" type="button">?

javascript:

$("#changePanel").click(function() {
    var data = "foobar";
    $("#panel").hide().html(data).fadeIn('fast');
});?

css:

div {
    padding: 1em;
    background-color: #00c000;
}

input {
    padding: .25em 1em;
}?

.fa-file-o {
    position: absolute;
    left: 50px;
    top: 15px;
    color: #ffffff
}

<div>
 <span class="fa fa-file-o"></span>
 <input type="button" name="" value="IMPORT FILE"/>
</div>

Easiest way to check if a row exists:

$lectureName = mysql_real_escape_string($lectureName);  // SECURITY!
$result = mysql_query("SELECT 1 FROM preditors_assigned WHERE lecture_name='$lectureName' LIMIT 1");
if (mysql_fetch_row($result)) {
    return 'Assigned';
} else {
    return 'Available';
}

No need to mess with arrays and field names.

may be:

UIImage *img = [[UIImage alloc] init];

and when you want to change the image:

img = [UIImage imageNamed:@"nameOfPng.png"];

but the object wasn't in the same place in the memory, but if you use the pointer, the same pointer will be point to the last image loaded.

Here is a fully functional example of what you are trying to accomplish. I created the example inside of hyperdev rather than jsFiddle so that you could see the server-side and client-side code.

View Code: https://hyperdev.com/#!/project/destiny-authorization

View Working Application: https://destiny-authorization.hyperdev.space/

This code creates a handler for a get request that returns a random string:

app.get("/string", function(req, res) {
    var strings = ["string1", "string2", "string3"]
    var n = Math.floor(Math.random() * strings.length)
    res.send(strings[n])
});

This jQuery code then makes the ajax request and receives the random string from the server.

$.get("/string", function(string) {
  $('#txtString').val(string);
});

Note that this example is based on code from Jamund Ferguson's answer so if you find this useful be sure to upvote him as well. I just thought this example would help you to see how everything fits together.

The rename method takes a dictionary for the index which applies to index values.
You want to rename to index level's name:

df.index.names = ['Date']

A good way to think about this is that columns and index are the same type of object (Index or MultiIndex), and you can interchange the two via transpose.

This is a little bit confusing since the index names have a similar meaning to columns, so here are some more examples:

In [1]: df = pd.DataFrame([[1, 2, 3], [4, 5 ,6]], columns=list('ABC'))

In [2]: df
Out[2]: 
   A  B  C
0  1  2  3
1  4  5  6

In [3]: df1 = df.set_index('A')

In [4]: df1
Out[4]: 
   B  C
A      
1  2  3
4  5  6

You can see the rename on the index, which can change the value 1:

In [5]: df1.rename(index={1: 'a'})
Out[5]: 
   B  C
A      
a  2  3
4  5  6

In [6]: df1.rename(columns={'B': 'BB'})
Out[6]: 
   BB  C
A       
1   2  3
4   5  6

Whilst renaming the level names:

In [7]: df1.index.names = ['index']
        df1.columns.names = ['column']

Note: this attribute is just a list, and you could do the renaming as a list comprehension/map.

In [8]: df1
Out[8]: 
column  B  C
index       
1       2  3
4       5  6

That code doesn't work very well i fixed it a little bit

var el = $('.caja-pago');
var elpos_original = el.offset().top;

 $(window).scroll(function(){
     var elpos = el.offset().top;
     var windowpos = $(window).scrollTop();
     var finaldestination = windowpos;
     if(windowpos<elpos_original) {
         finaldestination = elpos_original;
         el.stop().animate({'top':400},500);
     } else {
         el.stop().animate({'top':windowpos+10},500);
     }
 });

Simply use

$(document).height() // - $('body').offset().top

and / or

$(window).height()

instead of $('body').height();

There's an excellent presentation by Raymond Hettinger, titled Transforming Code into Beautiful, Idiomatic Python, in which he briefly addresses the history of the for ... else construct. The relevant section is "Distinguishing multiple exit points in loops" starting at 15:50 and continuing for about three minutes. Here are the high points:

• The for ... else construct was devised by Donald Knuth as a replacement for certain GOTO use cases;
• Reusing the else keyword made sense because "it's what Knuth used, and people knew, at that time, all [for statements] had embedded an if and GOTO underneath, and they expected the else;"
• In hindsight, it should have been called "no break" (or possibly "nobreak"), and then it wouldn't be confusing.*

So, if the question is, "Why don't they change this keyword?" then Cat Plus Plus probably gave the most accurate answer – at this point, it would be too destructive to existing code to be practical. But if the question you're really asking is why else was reused in the first place, well, apparently it seemed like a good idea at the time.

Personally, I like the compromise of commenting # no break in-line wherever the else could be mistaken, at a glance, as belonging inside the loop. It's reasonably clear and concise. This option gets a brief mention in the summary that Bjorn linked at the end of his answer:

For completeness, I should mention that with a slight change in syntax, programmers who want this syntax can have it right now:

for item in sequence:
    process(item)
else:  # no break
    suite

_{* Bonus quote from that part of the video: "Just like if we called lambda makefunction, nobody would ask, 'What does lambda do?'"}

'temp_C' is a key inside dictionary that is inside a list that is inside a dictionary

This way works:

wjson['data']['current_condition'][0]['temp_C']
>> '10'

You can use prop() for this, as Before jQuery 1.6, the .attr() method sometimes took property values into account when retrieving some attributes, which could cause inconsistent behavior. As of jQuery 1.6, the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.

var prop=false;
if(value == 1) {
   prop=true; 
}
$('#checkbox').prop('checked',prop);

or simply,

$('#checkbox').prop('checked',(value == 1));

Snippet

$(document).ready(function() {_x000D_
  var chkbox = $('.customcheckbox');_x000D_
  $(".customvalue").keyup(function() {_x000D_
    chkbox.prop('checked', this.value==1);_x000D_
  });_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<h4>This is a domo to show check box is checked_x000D_
if you enter value 1 else check box will be unchecked </h4>_x000D_
Enter a value:_x000D_

svn revert filename 

this should revert a single file.

NSString *string = @"hello bla bla";
if ([string rangeOfString:@"bla"].location == NSNotFound) {
  NSLog(@"string does not contain bla");
} else {
  NSLog(@"string contains bla!");
}

The key is noticing that rangeOfString: returns an NSRange struct, and the documentation says that it returns the struct {NSNotFound, 0} if the "haystack" does not contain the "needle".

And if you're on iOS 8 or OS X Yosemite, you can now do: (*NOTE: This WILL crash your app if this code is called on an iOS7 device).

NSString *string = @"hello bla blah";
if ([string containsString:@"bla"]) {
  NSLog(@"string contains bla!");
} else {
  NSLog(@"string does not contain bla");
}

(This is also how it would work in Swift)

It would be helpful to understand why you need to do this with lodash. If you just want to check if a key exists in an object, you don't need lodash.

myObject.options.hasOwnProperty('property');

If your looking to see if a value exists, you can use _.invert

_.invert(myObject.options)[value]

For multi-selects:

$("#yourdropdownid :selected").map(function(i, v) { return $.trim($(v).text()); }

This usually works for me:

_x000D_
_x000D_
.parent {_x000D_
  min-height: 100px;_x000D_
  background-color: green;_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  height: inherit;_x000D_
  width: 100%;_x000D_
  background-color: red;_x000D_
}

What about -mmin?

find /var/www/html/audio -daystart -maxdepth 1 -mmin +59 -type f -name "*.mp3" \

Also, make sure to test this first!

... -exec echo rm -f '{}' \;
          ^^^^ Add the 'echo' so you just see the commands that are going to get
               run instead of actual trying them first.

This one normally catches me when I run from IIS and the app pool for the default site is set to .NET version 2.0. When using IIS from visual studio it creates a virtual directory but still runs under the default site's app pool. If using the build in web server, right click on your web project, go to properties and make sure you're running it under the right version of .NET. On IIS check the .NET version on your app pool.

Following on from my last comment about how the project was created - are you correctly including the assemblies, as below (taken from the default web.config file generated by the MVC3 project template in VS10):

<compilation debug="true" targetFramework="4.0">
      <assemblies>
        <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
        <add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
        <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
        <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
        <add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
      </assemblies>
</compilation>

It's may be a little bit late, but here is more suitable code, for example when you need to use loops:

            List<int> genered = new List<int>();

            Random rnd = new Random();

            for(int x = 0; x < files.Length; x++)
            {
                int value = rnd.Next(0, files.Length - 1);
                while (genered.Contains(value))
                {
                    value = rnd.Next(0, files.Length - 1);
                }
                genered.Add(value);

                returnFiles[x] = files[value];
            }

This works

declare @v int=A
select * from Table_Name where XYZ=202 
and 
dbkey=(case @v  when A then 'Some Value 1'
else 'Some Value 2'
end)

If the string is Unicode the easiest way is:

import base64                                                        

a = base64.b64encode(bytes(u'complex string: ñáéíóúÑ', "utf-8"))

# a: b'Y29tcGxleCBzdHJpbmc6IMOxw6HDqcOtw7PDusOR'

b = base64.b64decode(a).decode("utf-8", "ignore")                    

print(b)
# b :complex string: ñáéíóúÑ

[Update: As of its 4.0 release, Express no longer uses Connect. However, Express is still compatible with middleware written for Connect. My original answer is below.]

I'm glad you asked about this, because it's definitely a common point of confusion for folks looking at Node.js. Here's my best shot at explaining it:

• Node.js itself offers an http module, whose createServer method returns an object that you can use to respond to HTTP requests. That object inherits the http.Server prototype.

• Connect also offers a createServer method, which returns an object that inherits an extended version of http.Server. Connect's extensions are mainly there to make it easy to plug in middleware. That's why Connect describes itself as a "middleware framework," and is often analogized to Ruby's Rack.

• Express does to Connect what Connect does to the http module: It offers a createServer method that extends Connect's Server prototype. So all of the functionality of Connect is there, plus view rendering and a handy DSL for describing routes. Ruby's Sinatra is a good analogy.

• Then there are other frameworks that go even further and extend Express! Zappa, for instance, which integrates support for CoffeeScript, server-side jQuery, and testing.

Here's a concrete example of what's meant by "middleware": Out of the box, none of the above serves static files for you. But just throw in connect.static (a middleware that comes with Connect), configured to point to a directory, and your server will provide access to the files in that directory. Note that Express provides Connect's middlewares also; express.static is the same as connect.static. (Both were known as staticProvider until recently.)

My impression is that most "real" Node.js apps are being developed with Express these days; the features it adds are extremely useful, and all of the lower-level functionality is still there if you want it.

Service references deal with endpoints and bindings, which are completely configurable. They let you point your client proxy to a WCF via any transport protocol (HTTP, TCP, Shared Memory, etc)

They are designed to work with WCF.

If you use a WebProxy, you are pretty much binding yourself to using WCF over HTTP

booleanExpression ? trueValue : falseValue;

Example:

string itemText = count > 1 ? "items" : "item";

Note that __file__ will give the file where this code resides, which can be imported and different from the main file being interpreted. To get the main file, the special __main__ module can be used:

import __main__ as main
print(main.__file__)

Note that __main__.__file__ works in Python 2.7 but not in 3.2, so use the import-as syntax as above to make it portable.

You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save (or the before_validation) callback. Here's an example of the relevant code for a model like yours:

class Place < ActiveRecord::Base   before_save do |place|     place.city = place.city.downcase.titleize     place.country = place.country.downcase.titleize   end end 

You can also check out the Ruby on Rails guide for more info.

To answer you question more directly, something like this would work:

<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>   

This just means if f.object.city exists, display the titlecase version of it, and if it doesn't display a blank string.

You, or most likely your sysadmin, will need to login as root and run the chown command: http://www.computerhope.com/unix/uchown.htm

Through this command you will become the owner of the file.

Or, you can be a member of a group that owns this file and then you can use chmod.

But, talk with your sysadmin.

you can also try divmod(x, y) which returns a tuple (x // y, x % y)

overflow:hidden prevents collapsing margins but it's not free of side effects - namely it... hides overflow.

Apart form this and what you've mentioned you just have to learn live with it and learn for this day when they are actually useful (comes every 3 to 5 years).

Current memory usage of the current process on Linux, for Python 2, Python 3, and pypy, without any imports:

def getCurrentMemoryUsage():
    ''' Memory usage in kB '''

    with open('/proc/self/status') as f:
        memusage = f.read().split('VmRSS:')[1].split('\n')[0][:-3]

    return int(memusage.strip())

It reads the status file of the current process, takes everything after VmRSS:, then takes everything before the first newline (isolating the value of VmRSS), and finally cuts off the last 3 bytes which are a space and the unit (kB).
To return, it strips any whitespace and returns it as a number.

Tested on Linux 4.4 and 4.9, but even an early Linux version should work: looking in man proc and searching for the info on the /proc/$PID/status file, it mentions minimum versions for some fields (like Linux 2.6.10 for "VmPTE"), but the "VmRSS" field (which I use here) has no such mention. Therefore I assume it has been in there since an early version.

Here it is:

select player_name, player_salary, (player_salary * 1.1) as player_newsalary
from player 
order by player_name, player_salary, player_newsalary desc

You don't need to "group by" if there is only one instance of a player in the table.

New features have been added to MATLAB recently:

String arrays were introduced in R2016b (as Budo and gnovice already mentioned):

String arrays store pieces of text and provide a set of functions for working with text as data. You can index into, reshape, and concatenate strings arrays just as you can with arrays of any other type.

In addition, starting in R2017a, you can create a string using double quotes "".

Therefore if your MATLAB version is >= R2017a, the following will do:

for i = 1:3
    Names(i) = "Sample Text";
end

Check the output:

>> Names

Names = 

  1×3 string array

    "Sample Text"    "Sample Text"    "Sample Text"

No need to deal with cell arrays anymore.

There's also another way to do this-

select TO_CHAR(SA.[RequestStartDate] , 'DD/MM/YYYY') as RequestStartDate from ... ;

for example i tried all above for characters it fails but that worked for me >> reserved a pointer then assign values

char A[];
A = new char[]{'a', 'b', 'a', 'c', 'd', 'd', 'e', 'f', 'q', 'r'};

In my case I selected the error marker in the Problems tab and deleted it since the Java's file main method was being executed correctly. That is some glitch in Eclipse Neon with the multitude of plugins it has installed.

If you are looking for a solution to your particular case, it would be:

Date date = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'").parse("2012-05-20T09:00:00.000Z");
String formattedDate = new SimpleDateFormat("dd/MM/yyyy, Ka").format(date);

No Worries! I have found the solution! I just installed https://msdn.microsoft.com/en-us/windows/desktop/bg162891.aspx and it all worked fine :)

Since it's not mentioned what database you mean I'm assuming SQL Server. Below solution works for both 2005 and 2008.

You have to create table with VARBINARY(MAX) as one of the columns. In my example I've created Table Raporty with column RaportPlik being VARBINARY(MAX) column.

Method to put file into database from drive:

public static void databaseFilePut(string varFilePath) {
    byte[] file;
    using (var stream = new FileStream(varFilePath, FileMode.Open, FileAccess.Read)) {
        using (var reader = new BinaryReader(stream)) {
            file = reader.ReadBytes((int) stream.Length);       
        }          
    }
    using (var varConnection = Locale.sqlConnectOneTime(Locale.sqlDataConnectionDetails))
    using (var sqlWrite = new SqlCommand("INSERT INTO Raporty (RaportPlik) Values(@File)", varConnection)) {
        sqlWrite.Parameters.Add("@File", SqlDbType.VarBinary, file.Length).Value = file;
        sqlWrite.ExecuteNonQuery();
    }
}

This method is to get file from database and save it on drive:

public static void databaseFileRead(string varID, string varPathToNewLocation) {
    using (var varConnection = Locale.sqlConnectOneTime(Locale.sqlDataConnectionDetails))
    using (var sqlQuery = new SqlCommand(@"SELECT [RaportPlik] FROM [dbo].[Raporty] WHERE [RaportID] = @varID", varConnection)) {
        sqlQuery.Parameters.AddWithValue("@varID", varID);
        using (var sqlQueryResult = sqlQuery.ExecuteReader())
            if (sqlQueryResult != null) {
                sqlQueryResult.Read();
                var blob = new Byte[(sqlQueryResult.GetBytes(0, 0, null, 0, int.MaxValue))];
                sqlQueryResult.GetBytes(0, 0, blob, 0, blob.Length);
                using (var fs = new FileStream(varPathToNewLocation, FileMode.Create, FileAccess.Write)) 
                    fs.Write(blob, 0, blob.Length);
            }
    }
}

This method is to get file from database and put it as MemoryStream:

public static MemoryStream databaseFileRead(string varID) {
    MemoryStream memoryStream = new MemoryStream();
    using (var varConnection = Locale.sqlConnectOneTime(Locale.sqlDataConnectionDetails))
    using (var sqlQuery = new SqlCommand(@"SELECT [RaportPlik] FROM [dbo].[Raporty] WHERE [RaportID] = @varID", varConnection)) {
        sqlQuery.Parameters.AddWithValue("@varID", varID);
        using (var sqlQueryResult = sqlQuery.ExecuteReader())
            if (sqlQueryResult != null) {
                sqlQueryResult.Read();
                var blob = new Byte[(sqlQueryResult.GetBytes(0, 0, null, 0, int.MaxValue))];
                sqlQueryResult.GetBytes(0, 0, blob, 0, blob.Length);
                //using (var fs = new MemoryStream(memoryStream, FileMode.Create, FileAccess.Write)) {
                memoryStream.Write(blob, 0, blob.Length);
                //}
            }
    }
    return memoryStream;
}

This method is to put MemoryStream into database:

public static int databaseFilePut(MemoryStream fileToPut) {
        int varID = 0;
        byte[] file = fileToPut.ToArray();
        const string preparedCommand = @"
                    INSERT INTO [dbo].[Raporty]
                               ([RaportPlik])
                         VALUES
                               (@File)
                        SELECT [RaportID] FROM [dbo].[Raporty]
            WHERE [RaportID] = SCOPE_IDENTITY()
                    ";
        using (var varConnection = Locale.sqlConnectOneTime(Locale.sqlDataConnectionDetails))
        using (var sqlWrite = new SqlCommand(preparedCommand, varConnection)) {
            sqlWrite.Parameters.Add("@File", SqlDbType.VarBinary, file.Length).Value = file;

            using (var sqlWriteQuery = sqlWrite.ExecuteReader())
                while (sqlWriteQuery != null && sqlWriteQuery.Read()) {
                    varID = sqlWriteQuery["RaportID"] is int ? (int) sqlWriteQuery["RaportID"] : 0;
                }
        }
        return varID;
    }

Happy coding :-)

The correct way to do this as of v4 is:

$('.select2-chosen').select2('data')[0].text

It is undocumented so could break in the future without warning.

You will probably want to check if there is a selection first however:

var s = $('.select2-chosen');

if(s.select2('data') && !!s.select2('data')[0]){
    //do work
}

These didn't work for me (SQL2008 Enterprise), I also couldn't see any running processes or users connected to the DB. Restarting the server (Right click on Sql Server in Management Studio and pick Restart) allowed me to restore the DB.

print "bla: ", $myvar =~ tr{a}{b},"\n";

But if you just want to tell the difference between an odd iteration and an even iteration, this works just fine:

If i Mod 2 > 0 then 'this is an odd 
   'Do Something
Else 'it is even
   'Do Something Else
End If

public byte[] longToBytes(long x) {
    ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
    buffer.putLong(x);
    return buffer.array();
}

public long bytesToLong(byte[] bytes) {
    ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
    buffer.put(bytes);
    buffer.flip();//need flip 
    return buffer.getLong();
}

Or wrapped in a class to avoid repeatedly creating ByteBuffers:

public class ByteUtils {
    private static ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);    

    public static byte[] longToBytes(long x) {
        buffer.putLong(0, x);
        return buffer.array();
    }

    public static long bytesToLong(byte[] bytes) {
        buffer.put(bytes, 0, bytes.length);
        buffer.flip();//need flip 
        return buffer.getLong();
    }
}

Since this is getting so popular, I just want to mention that I think you're better off using a library like Guava in the vast majority of cases. And if you have some strange opposition to libraries, you should probably consider this answer first for native java solutions. I think the main thing my answer really has going for it is that you don't have to worry about the endian-ness of the system yourself.

If session.cookie_lifetime is 0, the session cookie lives until the browser is quit.

EDIT: Others have mentioned the session.gc_maxlifetime setting. When session garbage collection occurs, the garbage collector will delete any session data that has not been accessed in longer than session.gc_maxlifetime seconds. To set the time-to-live for the session cookie, call session_set_cookie_params() or define the session.cookie_lifetime PHP setting. If this setting is greater than session.gc_maxlifetime, you should increase session.gc_maxlifetime to a value greater than or equal to the cookie lifetime to ensure that your sessions won't expire.

Using bash regular expressions:

re="http://([^/]+)/"
if [[ $name =~ $re ]]; then echo ${BASH_REMATCH[1]}; fi

Edit - OP asked for explanation of syntax. Regular expression syntax is a large topic which I can't explain in full here, but I will attempt to explain enough to understand the example.

re="http://([^/]+)/"

This is the regular expression stored in a bash variable, re - i.e. what you want your input string to match, and hopefully extract a substring. Breaking it down:

• http:// is just a string - the input string must contain this substring for the regular expression to match
• [] Normally square brackets are used say "match any character within the brackets". So c[ao]t would match both "cat" and "cot". The ^ character within the [] modifies this to say "match any character except those within the square brackets. So in this case [^/] will match any character apart from "/".
• The square bracket expression will only match one character. Adding a + to the end of it says "match 1 or more of the preceding sub-expression". So [^/]+ matches 1 or more of the set of all characters, excluding "/".
• Putting () parentheses around a subexpression says that you want to save whatever matched that subexpression for later processing. If the language you are using supports this, it will provide some mechanism to retrieve these submatches. For bash, it is the BASH_REMATCH array.
• Finally we do an exact match on "/" to make sure we match all the way to end of the fully qualified domain name and the following "/"

Next, we have to test the input string against the regular expression to see if it matches. We can use a bash conditional to do that:

if [[ $name =~ $re ]]; then
    echo ${BASH_REMATCH[1]}
fi

In bash, the [[ ]] specify an extended conditional test, and may contain the =~ bash regular expression operator. In this case we test whether the input string $name matches the regular expression $re. If it does match, then due to the construction of the regular expression, we are guaranteed that we will have a submatch (from the parentheses ()), and we can access it using the BASH_REMATCH array:

• Element 0 of this array ${BASH_REMATCH[0]} will be the entire string matched by the regular expression, i.e. "http://www.google.com/".
• Subsequent elements of this array will be subsequent results of submatches. Note you can have multiple submatch () within a regular expression - The BASH_REMATCH elements will correspond to these in order. So in this case ${BASH_REMATCH[1]} will contain "www.google.com", which I think is the string you want.

Note that the contents of the BASH_REMATCH array only apply to the last time the regular expression =~ operator was used. So if you go on to do more regular expression matches, you must save the contents you need from this array each time.

This may seem like a lengthy description, but I have really glossed over several of the intricacies of regular expressions. They can be quite powerful, and I believe with decent performance, but the regular expression syntax is complex. Also regular expression implementations vary, so different languages will support different features and may have subtle differences in syntax. In particular escaping of characters within a regular expression can be a thorny issue, especially when those characters would have an otherwise different meaning in the given language.

Note that instead of setting the $re variable on a separate line and referring to this variable in the condition, you can put the regular expression directly into the condition. However in bash 3.2, the rules were changed regarding whether quotes around such literal regular expressions are required or not. Putting the regular expression in a separate variable is a straightforward way around this, so that the condition works as expected in all bash versions that support the =~ match operator.

You need to define height of ul or your div and set overflow equals to auto as below:

<ul style="width: 300px; height: 200px; overflow: auto">
  <li>text</li>
  <li>text</li>

Here is a shell script that uses Awk's gsub function to replace the text you're searching for with the proper escape sequence to display it in bright red:

#! /bin/bash
awk -vstr=$1 'BEGIN{repltext=sprintf("%c[1;31;40m&%c[0m", 0x1B,0x1B);}{gsub(str,repltext); print}' $2

Use it like so:

$ ./cgrep pattern [file]

Unfortunately, it doesn't have all the functionality of grep.

It seems that Scrapy fails because installing Twisted fails, which fails because incremental fails. Running pip install --upgrade pip && pip install --upgrade incremental fixed this for me.

Money transfered online form one account to another account is stateful, because the receving account has information about the sender. Handing over cash from a person to another person, this transaction is statless, because after cash is recived the identity of the giver is not there with the cash.

You got the order wrong. The if should be after the for (unless it is in an if-else ternary operator)

[y for y in a if y not in b]

This would work however:

[y if y not in b else other_value for y in a]

I have not tried in Selenium, but for Galen test this is working,

var list = driver.findElementByID("periodID"); // this will return web element

list.click(); // this will open the dropdown list.

list.typeText("14w"); // this will select option "14w".

You can try this in selenium, the galen and selenium working are similar.

contents = open(filename)

This gives you generator so you must save somewhere the values though, or

contents = [line for line in open(filename)]

This does the saving to list explicit close is not then possible (at least with my knowledge of Python).

You can use the built-in function:

extract($_POST);

it will create a variable for each entry in $_POST.

I would like to answer your question, as there are various methods - here I’ll talk about the code that is widely used.

So, for hiding the sheet:

In my and possibly @BIOHAZARD case it was nginx proxy timeout. In default it's 60 sec without activity in socket

I changed it to 24h in nginx and it resolved problem

proxy_read_timeout 86400s;
proxy_send_timeout 86400s;

Since it depends on the version of your JRE which is used to run the maven command you propably dont want to disable DocLint per default in your pom.xml

Hence, from command line you can use the switch -Dadditionalparam=-Xdoclint:none.

Example: mvn clean install -Dadditionalparam=-Xdoclint:none

Another alternative might be to use Flask-APScheduler which plays nicely with Flask, e.g.:

• Loads scheduler configuration from Flask configuration,
• Loads job definitions from Flask configuration

I magically solved all my cookie problems with this one line in onCreate:

CookieHandler.setDefault(new CookieManager());

edit: it stopped working today. :( what the crap, android.

If your table is only 2 columns across, you can easily reach the second td with the adjacent sibling selector, which IE8 does support along with :first-child:

.editor td:first-child
{
    width: 150px; 
}

.editor td:first-child + td input,
.editor td:first-child + td textarea
{
    width: 500px;
    padding: 3px 5px 5px 5px;
    border: 1px solid #CCC; 
}

Otherwise, you'll have to use a JS selector library like jQuery, or manually add a class to the last td, as suggested by James Allardice.
