The source tree you are requiring is still available within the git repository, however, you will need the SHA1 of the commit that you are interested in. I would assume that you can get the SHA1 from the current clone you have?

If you can get that SHA1, the you can create a branch / reset there to have the identical repository.

Commands as per Rui's answer

for the latest Chrome version, this works for me :

var win = window.open("", "Title", "toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=780,height=200,top="+(screen.height-400)+",left="+(screen.width-840));
win.document.body.innerHTML = 'iframe width="100%" height="100%" src="data:application/pdf;base64,"+base64+"></iframe>';

Thanks

Just a little addition to the answer of @dAm2k :

In addition to sudo apt-get remove --purge mysql\*

I've done a sudo apt-get remove --purge mariadb\*.

I seems that in the new release of debian (stretch), when you install mysql it install mariadb package with it.

Hope it helps.

Visual Studio 2015/2017's live debugger is injecting code that contains the deprecated call.

I know it is an old question, but I was struggling finding the answer myself. Here is what I have come up with:

Python 3:

>>> num_dict = {'num': 0.123, 'num2': 0.127}
>>> "{0[num]:.2f}_{0[num2]:.2f}".format(num_dict) 
0.12_0.13

If your data is already serialized:

a) send a JSON response

public function someAction()
{
    $response = new Response();
    $response->setContent(file_get_contents('path/to/file'));
    $response->headers->set('Content-Type', 'application/json');
    return $response;
}

b) send a JSONP response (with callback)

public function someAction()
{
    $response = new Response();
    $response->setContent('/**/FUNCTION_CALLBACK_NAME(' . file_get_contents('path/to/file') . ');');
    $response->headers->set('Content-Type', 'text/javascript');
    return $response;
}

If your data needs be serialized:

c) send a JSON response

public function someAction()
{
    $response = new JsonResponse();
    $response->setData([some array]);
    return $response;
}

d) send a JSONP response (with callback)

public function someAction()
{
    $response = new JsonResponse();
    $response->setData([some array]);
    $response->setCallback('FUNCTION_CALLBACK_NAME');
    return $response;
}

e) use groups in Symfony 3.x.x

Create groups inside your Entities

<?php

namespace Mindlahus;

use Symfony\Component\Serializer\Annotation\Groups;

/**
 * Some Super Class Name
 *
 * @ORM    able("table_name")
 * @ORM\Entity(repositoryClass="SomeSuperClassNameRepository")
 * @UniqueEntity(
 *  fields={"foo", "boo"},
 *  ignoreNull=false
 * )
 */
class SomeSuperClassName
{
    /**
     * @Groups({"group1", "group2"})
     */
    public $foo;
    /**
     * @Groups({"group1"})
     */
    public $date;

    /**
     * @Groups({"group3"})
     */
    public function getBar() // is* methods are also supported
    {
        return $this->bar;
    }

    // ...
}

Normalize your Doctrine Object inside the logic of your application

<?php

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Serializer\Mapping\Factory\ClassMetadataFactory;
// For annotations
use Doctrine\Common\Annotations\AnnotationReader;
use Symfony\Component\Serializer\Mapping\Loader\AnnotationLoader;
use Symfony\Component\Serializer\Serializer;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
use Symfony\Component\Serializer\Encoder\JsonEncoder;

...

$repository = $this->getDoctrine()->getRepository('Mindlahus:SomeSuperClassName');
$SomeSuperObject = $repository->findOneById($id);

$classMetadataFactory = new ClassMetadataFactory(new AnnotationLoader(new AnnotationReader()));
$encoder = new JsonEncoder();
$normalizer = new ObjectNormalizer($classMetadataFactory);
$callback = function ($dateTime) {
    return $dateTime instanceof \DateTime
        ? $dateTime->format('m-d-Y')
        : '';
};
$normalizer->setCallbacks(array('date' => $callback));
$serializer = new Serializer(array($normalizer), array($encoder));
$data = $serializer->normalize($SomeSuperObject, null, array('groups' => array('group1')));

$response = new Response();
$response->setContent($serializer->serialize($data, 'json'));
$response->headers->set('Content-Type', 'application/json');
return $response;

This can't be done by using a Comparator, as it will always get the key of the map to compare. TreeMap can only sort by the key.

Based on your requirements you can also do the following without libraries like jQuery:

Add this to your head:

window.onload = function () {
    document.getElementById("frmSubmit").onsubmit = function onSubmit(form) {
        var isValid = true;
        //validate your elems here
        isValid = false;

        if (!isValid) {
            alert("Please check your fields!");
            return false;
        }
        else {
            //you are good to go
            return true;
        }
    }
}

And your form may still look something like:

    <form id="frmSubmit" action="/Submit">
        <input type="submit" value="Submit" />
    </form>

Turning off safe mode in Mysql workbench 6.3.4.0

Edit menu => Preferences => SQL Editor : Other section: click on "Safe updates" ... to uncheck option

Perhaps not the most elegant solution but it works if you are not too picky!

bool IsInteger(double num) {
    return !num.ToString("0.################").Contains(".");
}

I had the same problem and solved it by changing the value for the param max_execution_time in php.ini, like this:

max_execution_time = 360      ; Maximum execution time of each script, in seconds (I CHANGED THIS VALUE)
max_input_time = 120          ; Maximum amount of time each script may spend parsing request data
;max_input_nesting_level = 64 ; Maximum input variable nesting level
memory_limit = 128M           ; Maximum amount of memory a script may consume (128MB by default)

I hope this could help you.

I'd say there is no preferred method, it all depends on what you're going to do with the response. If the results are going to be used together in further processing then structures make sense, if not I'd tend to pass then as individual references unless the function was going to be used in a composite statement:

x = divide( x, y, z ) + divide( a, b, c );

I often choose to pass 'out structures' by reference in the parameter list rather than having the pass by copy overhead of returning a new structure (but this is sweating the small stuff).

void divide(int dividend, int divisor, Answer &ans)

Are out parameters confusing? A parameter sent as reference suggests the value is going to change (as opposed to a const reference). Sensible naming also removes confusion.

Here is a method to get lines between two line numbers in a file:

import sys

def file_line(name,start=1,end=sys.maxint):
    lc=0
    with open(s) as f:
        for line in f:
            lc+=1
            if lc>=start and lc<=end:
                yield line


s='/usr/share/dict/words'
l1=list(file_line(s,235880))
l2=list(file_line(s,1,10))
print l1
print l2

Output:

['Zyrian\n', 'Zyryan\n', 'zythem\n', 'Zythia\n', 'zythum\n', 'Zyzomys\n', 'Zyzzogeton\n']
['A\n', 'a\n', 'aa\n', 'aal\n', 'aalii\n', 'aam\n', 'Aani\n', 'aardvark\n', 'aardwolf\n', 'Aaron\n']

Just call it with one parameter to get from line n -> EOF

The numerical value seems to be missing from your price definition. Try the following:

<xs:simpleType name="curr">
  <xs:restriction base="xs:string">
    <xs:enumeration value="pounds" />
    <xs:enumeration value="euros" />
    <xs:enumeration value="dollars" />
  </xs:restriction>
</xs:simpleType>



<xs:element name="price">
        <xs:complexType>
            <xs:extension base="xs:decimal">
              <xs:attribute name="currency" type="curr"/>
            </xs:extension>
        </xs:complexType>
</xs:element>

This should work.

SELECT a.[CUSTOMER ID], a.[NAME], SUM(b.[AMOUNT]) AS [TOTAL AMOUNT]
FROM RES_DATA a INNER JOIN INV_DATA b
ON a.[CUSTOMER ID]=b.[CUSTOMER ID]
GROUP BY a.[CUSTOMER ID], a.[NAME]

I tested it with SQL Fiddle against SQL Server 2008: http://sqlfiddle.com/#!3/1cad5/1

Basically what's happening here is that, because of the join, you are getting the same row on the "left" (i.e. from the RES_DATA table) for every row on the "right" (i.e. the INV_DATA table) that has the same [CUSTOMER ID] value. When you group by just the columns on the left side, and then do a sum of just the [AMOUNT] column from the right side, it keeps the one row intact from the left side, and sums up the matching values from the right side.

Download openSSL -> Install it -> it would usually install in C:\OpenSSL

then open cmd and type

It will ask you for password which is android.

I used skimage. You can create a collection and access elements the standard way, i.e. col[index]. This will give you the RGB values.

from skimage.io import imread_collection

#your path 
col_dir = 'cats/*.jpg'

#creating a collection with the available images
col = imread_collection(col_dir)

I want to produce a complementary answer of nacho-soriano's solution ...

I recently search to solve a problem where a Java written application (a Talend ELT job in fact) want to connect to an Oracle database (11g and over) then randomly fail. OS is both RedHat Enterprise and CentOS. Job run very quily in time (no more than half a minute) and occur very often (approximately one run each 5 minutes).

Some times, during night-time as work-time, during database intensive-work usage as lazy work usage, in just a word randomly, connection fail with this message:

Problem explanation:

As detailed here

Oracle connection needs some random numbers to assume a good level of security. Linux random number generator produce some numbers bases keyboard and mouse activity (among others) and place them in a stack. You will grant me, on a server, there is not a big amount of such activity. So it can occur that softwares use more random number than generator can produce.

When the pool is empty, reads from /dev/random will block until additional environmental noise is gathered. And Oracle connection fall in timeout (60 seconds by default).

Solution 1 - Specific for one app solution

The solution is to give add two parameters given to the JVM while starting:

-Djava.security.egd=file:/dev/./urandom
-Dsecurerandom.source=file:/dev/./urandom

Note: the '/./' is important, do not drop it !

So the launch command line could be:

java -Djava.security.egd=file:/dev/./urandom -Dsecurerandom.source=file:/dev/./urandom -cp <classpath directives> appMainClass <app options and parameters>

One drawback of this solution is that numbers generated are a little less secure as randomness is impacted. If you don't work in a military or secret related industry this solution can be your.

Solution 2 - General Java JVM solution

As explained here

Both directives given in solution 1 can be put in Java security setting file.

Take a look at $JAVA_HOME/jre/lib/security/java.security

Change the line

securerandom.source=file:/dev/random

to

securerandom.source=file:/dev/urandom

Change is effective immediately for new running applications.

As for solution #1, one drawback of this solution is that numbers generated are a little less secure as randomness is impacted. This time, it's a global JVM impact. As for solution #1, if you don't work in a military or secret related industry this solution can be your.

We ideally should use "file:/dev/./urandom" after Java 5 as previous path will again point to /dev/random.

Reported Bug : https://bugs.openjdk.java.net/browse/JDK-6202721

Solution 3 - Hardware solution

Disclamer: I'm not linked to any of hardware vendor or product ...

If your need is to reach a high quality randomness level, you can replace your Linux random number generator software by a piece of hardware.

Some information are available here.

I know I am a bit late, but I took Regis_AG's answer and wrapped it in a helper class and it works great.

public class Toaster {
  private static final int SHORT_TOAST_DURATION = 2000;

  private Toaster() {}

  public static void makeLongToast(String text, long durationInMillis) {
    final Toast t = Toast.makeText(App.context(), text, Toast.LENGTH_SHORT);
    t.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL, 0, 0);

    new CountDownTimer(Math.max(durationInMillis - SHORT_TOAST_DURATION, 1000), 1000) {
      @Override
      public void onFinish() {
        t.show();
      }

      @Override
      public void onTick(long millisUntilFinished) {
        t.show();
      }
    }.start();
  }
}

In your application code, just do something like this:

    Toaster.makeLongToast("Toasty!", 8000);

On the basic question of why openssl is not found: Short answer:Some installation packages for openssl have a default openssl.cnf pre-included. Other packages do not. In the latter case you will include one from the link shown below; You can enter additional user-specifics --DN name,etc-- as needed.

From https://www.openssl.org/docs/manmaster/man5/config.html,I quote directly:

"OPENSSL LIBRARY CONFIGURATION

Applications can automatically configure certain aspects of OpenSSL using the master OpenSSL configuration file, or optionally an alternative configuration file. The openssl utility includes this functionality: any sub command uses the master OpenSSL configuration file unless an option is used in the sub command to use an alternative configuration file.

To enable library configuration the default section needs to contain an appropriate line which points to the main configuration section. The default name is openssl_conf which is used by the openssl utility. Other applications may use an alternative name such as myapplication_conf. All library configuration lines appear in the default section at the start of the configuration file.

The configuration section should consist of a set of name value pairs which contain specific module configuration information. The name represents the name of the configuration module. The meaning of the value is module specific: it may, for example, represent a further configuration section containing configuration module specific information. E.g.:"

So it appears one must self configure openssl.cnf according to your Distinguished Name (DN), along with other entries specific to your use.

Here is the template file from which you can generate openssl.cnf with your specific entries.

One Application actually has a demo installation that includes a demo .cnf file.

Additionally, if you need to programmatically access .cnf files, you can include appropriate headers --openssl/conf.h-- and parse your .cnf files using

CONF_modules_load_file(const char *filename, const char *appname,
                            unsigned long flags);

Here are docs for "CONF_modules_load_file";

Wrap the text in a span or similar and use the following CSS:

.your-div {
    position: relative;
}

.your-div span {
    position: absolute;
    bottom: 0;
    right: 0;
}

You should include the brackets as well . . .

<input type="checkbox" name="bla[]" value="1" />

therefore referencing it should be as be name='bla[]'

$(document).ready( function () { 

   $("input[name='bla[]']").each( function () {
       alert( $(this).val() );
   });

});

(I realise this is old, but it still comes up...)

If you do replace mysql_* with mysqli_* then bear in mind that a whole load of mysqli_* functions need the database link to be passed.

E.g.:

mysql_query($query)

becomes

mysqli_query($link, $query)

I.e., lots of checking required.

Use a for loop that ranges through all keys in prices:

for key, value in prices.items():
     print key
     print "price: %s" %value

Make sure that you change prices.items() to prices.iteritems() if you're using Python 2.x

this work with me

Try width:inherit to make the image take the width of it's container <div>. It will stretch/shrink it's height to maintain proportion. Don't set the height in the <div>, it will size to fit the image height.

}

    border:1px solid pink;
    width: 120px;

JSFiddle example

If you are using toolbar from AppCompat (android.support.v7.widget.Toolbar, >= revision 24, June 2016), the padding between the icon and the title can be changed with the following value :

  app:contentInsetStartWithNavigation="0dp"

To improve my answer, you can use it on your toolbar directly inside your activity or you can create a new layout file for your toolbar. In this case, you just have to import your toolbar's @id using the include property on each needed views.

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:elevation="4dp"
    app:contentInsetLeft="0dp"
    app:contentInsetStart="0dp"
    app:contentInsetStartWithNavigation="0dp">
</android.support.v7.widget.Toolbar>

You can then import your layout on your activity.xml

<include
        layout="@layout/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

Calling multiple functions on onClick for any element, you can create a wrapper function, something like this.

wrapperFunction = () => {
    //do something
    function 1();
    //do something
    function 2();
    //do something
    function 3();
}

These functions can be defined as a method on the parent class and then called from the wrapper function.

You may have the main element which will cause the onChange like this,

<a href='#' onClick={this.wrapperFunction}>Some Link</a>

Calling exactly super() is always redundant. It's explicitly doing what would be implicitly done otherwise. That's because if you omit a call to the super constructor, the no-argument super constructor will be invoked automatically anyway. Not to say that it's bad style; some people like being explicit.

However, where it becomes useful is when the super constructor takes arguments that you want to pass in from the subclass.

public class Animal {
   private final String noise;
   protected Animal(String noise) {
      this.noise = noise;
   }

   public void makeNoise() {
      System.out.println(noise);
   }
}

public class Pig extends Animal {
    public Pig() {
       super("Oink");
    }
}

We use a script which checks if a running container is started with the latest image. We also use upstart init scripts for starting the docker image.

#!/usr/bin/env bash
set -e
BASE_IMAGE="registry"
REGISTRY="registry.hub.docker.com"
IMAGE="$REGISTRY/$BASE_IMAGE"
CID=$(docker ps | grep $IMAGE | awk '{print $1}')
docker pull $IMAGE

for im in $CID
do
    LATEST=`docker inspect --format "{{.Id}}" $IMAGE`
    RUNNING=`docker inspect --format "{{.Image}}" $im`
    NAME=`docker inspect --format '{{.Name}}' $im | sed "s/\///g"`
    echo "Latest:" $LATEST
    echo "Running:" $RUNNING
    if [ "$RUNNING" != "$LATEST" ];then
        echo "upgrading $NAME"
        stop docker-$NAME
        docker rm -f $NAME
        start docker-$NAME
    else
        echo "$NAME up to date"
    fi
done

And init looks like

docker run -t -i --name $NAME $im /bin/bash

Just had the same issue. Wanted to dynamically trigger parametrized downstream jobs based on the outcome of some groovy scripting.

Unfortunately on our Jenkins it's not possible to run System Groovy scripts. Therefore I had to do a small workaround:

1. Run groovy script which creates a properties file where the environment variable to be set is specified

   def props = new File("properties.text")
   if (props.text == 'foo=bar') {
       props.text = 'foo=baz'
   } else {
       props.text = 'foo=bar'
   }
   

2. Use env inject plugin to inject the variable written into this script

   Inject environment variable
   Property file path: properties.text
   

After that I was able to use the variable 'foo' as parameter for the parametrized trigger plugin. Some kind of workaround. But works!

Assuming you want the full object, but only want to deal with distinctness by typeID, there's nothing built into LINQ to make this easy. (If you just want the typeID values, it's easy - project to that with Select and then use the normal Distinct call.)

In MoreLINQ we have the DistinctBy operator which you could use:

var distinct = list.DistinctBy(x => x.typeID);

This only works for LINQ to Objects though.

You can use a grouping or a lookup, it's just somewhat annoying and inefficient:

var distinct = list.GroupBy(x => x.typeID, (key, group) => group.First());

Unfortunately the switch option to mount a volume is only found in the run command.

docker run --help

-v, --volume list Bind mount a volume (default [])

There is a way you can work around this though so you won't have to reinstall the applications you've already set up on your container.

1. Export your container docker container export -o ./myimage.docker mycontainer
2. Import as an image docker import ./myimage.docker myimage
3. Then docker run -i -t -v /somedir --name mycontainer myimage /bin/bash

Allowing methods and constructors in enums surprised me. For example:

enum Cats {
  FELIX(2), SHEEBA(3), RUFUS(7);

  private int mAge;
  Cats(int age) {
    mAge = age;
  }
  public int getAge() {
    return mAge;
   }
}

You can even have a "constant specific class body" which allows a specific enum value to override methods.

More documentation here.

In Your HTML

<input type="button" name="Release" onclick="hello();" value="Click to Release" />

In Your JavaScript

<script type="text/javascript">
    function hello(){
        alert('Your message here');
    }
</script>

If you need to run PHP in JavaScript You need to use JQuery Ajax Function

<script type="text/javascript">
function hello(){
    $.ajax(
{     
 type:    'post',
 url:     'folder/my_php_file.php',
 data:    '&id=' + $('#id').val() + '&name=' +     $('#name').val(),
 dataType: 'json',
 //alert(data);
 success: function(data) 
 {
  //alert(data);
 }   
});
}
</script>

Now in your my_php_file.php file

<?php 
    echo 'hello';
?>

Good Luck !!!!!

$ adb shell
$su
# getenforce
Enforcing

now try

adb shell
su
chmod 777 /path/to/yout_file

exit from shell

open new CMD and try adb pull /path/to/yout_file

It will work fine now.

you'll have security problems because of this any application will be able to access your database.

You can use css with relative/absolute positioning if you want it responsive. Plus it can handle easily the multi-line.

https://jsfiddle.net/mgyp0jkk/

  <canvas id="myChart"></canvas>      
  <div class="absolute-center text-center">
    <p>Some text</p>
    <p>Some text</p>
  </div>
</div>

In my case it was a blank space at the beginning of the file which showed up clearly when I opened the file in Notepad, wasn't obvious in Visual Studio Code.

The add a new path to PYTHONPATH is doing in manually by:

adding the path to your ~/.bashrc profile, in terminal by:

vim ~/.bashrc

paste the following to your profile

export PYTHONPATH="${PYTHONPATH}:/User/johndoe/pythonModule"

then, make sure to source your bashrc profile when ever you run your code in terminal:

source ~/.bashrc

    final String EMAIL_PATTERN = "^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";
    pattern = Pattern.compile(EMAIL_PATTERN);
    matcher = pattern.matcher(email);
    return matcher.matches();
}

So, in an ideal world you'd have a spec for all pages in your site. You would also have a test infrastructure that could hit all your pages to test them.

You're presumably not in an ideal world. Why not do this...?

1. Create a mapping between the well known old URLs and the new ones. Redirect when you see an old URL. I'd possibly consider presenting a "this page has moved, it's new url is XXX, you'll be redirected shortly".

2. If you have no mapping, present a "sorry - this page has moved. Here's a link to the home page" message and redirect them if you like.

3. Log all redirects - especially the ones with no mapping. Over time, add mappings for pages that are important.

The only difference is that localStorage has a different expiration time, sessionStorage will only be accessible while and by the window that created it is open.
localStorage lasts until you delete it or the user deletes it.
Lets say that you wanted to save a login username and password you would want to use sessionStorageover localStorage for security reasons (ie. another person accessing their account at a later time).
But if you wanted to save a user's settings on their machine you would probably want localStorage. All in all:

localStorage - use for long term use.
sessionStorage - use when you need to store somthing that changes or somthing temporary

I got the same error in android studio. I was able to resolve it by running Build->Clean Project in the IDE.

As alluded to by Eric, you can use environ with ComputerName argument like so:

MsgBox Environ("USERNAME")

Some additional information that might be helpful for you to know:

1. The arguments are not case sensitive.
2. There is a slightly faster performing string version of the Environ function. To invoke it, use a dollar sign. (Ex: Environ$("username")) This will net you a small performance gain.
3. You can retrieve all System Environment Variables using this function. (Not just username.) A common use is to get the "ComputerName" value to see which computer the user is logging onto from.
4. I don't recommend it for most situations, but it can be occasionally useful to know that you can also access the variables with an index. If you use this syntax the the name of argument and the value are returned. In this way you can enumerate all available variables. Valid values are 1 - 255.

    Sub EnumSEVars()
        Dim strVar As String
        Dim i As Long
        For i = 1 To 255
            strVar = Environ$(i)
            If LenB(strVar) = 0& Then Exit For
            Debug.Print strVar
        Next
    End Sub

If you are using underscore js, it is easy to remove object based on key. http://underscorejs.org. Example:

  var temp1=[{id:1,name:"safeer"},  //temp array
             {id:2,name:"jon"},
             {id:3,name:"James"},
             {id:4,name:"deepak"},
             {id:5,name:"ajmal"}];

  var id = _.pluck(temp1,'id'); //get id array from temp1
  var ids=[2,5,10];             //ids to be removed
  var bool_ids=[];
  _.each(ids,function(val){
     bool_ids[val]=true;
  });
  _.filter(temp1,function(val){
     return !bool_ids[val.id];
  });

It follows the convention that static methods should be thread-safe, but actually in v2 that static api is a proxy to an instance method on a default instance: in the case protobuf-net, it internally minimises contention points, and synchronises the internal state when necessary. Basically the library goes out of its way to do things right so that you can have simple code.

"FirstRow" Is a restriction and therefor it's place in the where clause not in the select clause. And it's called rownum

select * from dual where rownum = 1;

take a look at shutil. shutil.copyfile(src, dst) will copy a file to another file.

Note that shutil.copyfile will not create directories that do not already exist. for that, use os.makedirs

There is no difference.

The Java Software Development Kit (Java SDK) used to be called the Java Development Kit (JDK) before the marketing department at Sun got crazy with the "tm" and terminology. For political reasons & for sanity, they call the meaningful names (jdk) & versions (1.2 / 1.3 / 1.4 1.5 / 1.6) "engineering" terms. The marketing terms are "Java2 platform" (aka jdk 1.2 thru 1.4) or Java5 (aka jdk 1.5) or Java6 (aka jdk1.6). I'm getting a headache just thinking about it.

this seemed to work for me, its similar to another answer but has some distinct differences:

- (void)viewDidLayoutSubviews
{     
   [self.collectionView layoutIfNeeded];
   NSArray *visibleItems = [self.collectionView indexPathsForVisibleItems];
   NSIndexPath *currentItem = [visibleItems objectAtIndex:0];
   NSIndexPath *nextItem = [NSIndexPath indexPathForItem:someInt inSection:currentItem.section];

   [self.collectionView scrollToItemAtIndexPath:nextItem atScrollPosition:UICollectionViewScrollPositionNone animated:YES];
}

Use:

System.Text.Encoding.ASCII.GetString(buf);

If you don't see a drawable folder for the DPI that you need, you can create it yourself. There's nothing magical about it; it's just a folder which needs to have the correct name.

I think the following is a good exhibit of Echo vs. Write-Host. Notice how test() actually returns an array of ints, not a single int as one could easily be led to believe.

function test {
    Write-Host 123
    echo 456 # AKA 'Write-Output'
    return 789
}

$x = test

Write-Host "x of type '$($x.GetType().name)' = $x"

Write-Host "`$x[0] = $($x[0])"
Write-Host "`$x[1] = $($x[1])"

Terminal output of the above:

123
x of type 'Object[]' = 456 789
$x[0] = 456
$x[1] = 789

You can use Record for this:

https://www.typescriptlang.org/docs/handbook/utility-types.html#recordkt

Example (A mapping between AppointmentStatus enum and some meta data):

  const iconMapping: Record<AppointmentStatus, Icon> = {
    [AppointmentStatus.Failed]: { Name: 'calendar times', Color: 'red' },
    [AppointmentStatus.Canceled]: { Name: 'calendar times outline', Color: 'red' },
    [AppointmentStatus.Confirmed]: { Name: 'calendar check outline', Color: 'green' },
    [AppointmentStatus.Requested]: { Name: 'calendar alternate outline', Color: 'orange' },
    [AppointmentStatus.None]: { Name: 'calendar outline', Color: 'blue' }
  }

Now with interface as value:

interface Icon { Name: string Color: string }

Usage:

const icon: SemanticIcon = iconMapping[appointment.Status]

We can do it by css like.

body {
  background: #000;
  background-image: linear-gradient(90deg, rgba(255, 255, 255, .3) 0%, rgba(231, 231, 231, .3) 22.39%, rgba(209, 209, 209,  .3) 42.6%, rgba(182, 182, 182, .3) 79.19%, rgba(156, 156, 156, .3) 104.86%);
  
}

Well any Javascript object functions sort-of like a "map"

randomObject['hello'] = 'world';

Typically people build simple objects for the purpose:

var myMap = {};

// ...

myMap[newKey] = newValue;

edit — well the problem with having an explicit "put" function is that you'd then have to go to pains to avoid having the function itself look like part of the map. It's not really a Javascripty thing to do.

13 Feb 2014 — modern JavaScript has facilities for creating object properties that aren't enumerable, and it's pretty easy to do. However, it's still the case that a "put" property, enumerable or not, would claim the property name "put" and make it unavailable. That is, there's still only one namespace per object.

var time = Date.now || function() {
  return +new Date;
};

time();

In case you are not matching numeric strings, always good to have common case:

.Where(oh => oh.Hierarchy.ToUpper().Contains(mySearchString.ToUpper()))

I have to dedupe a very big table with many columns and speed is important. Thus I use this method which works for any table:

delete T from 
(select Row_Number() Over(Partition By BINARY_CHECKSUM(*) order by %%physloc%% ) As RowNumber, * From MyTable) T
Where T.RowNumber > 1

You want to use regexp_substr() for this. This should work for your example:

select regexp_substr(val, '[^/]+/[^/]+', 1, 1) as part1,
       regexp_substr(val, '[^/]+$', 1, 1) as part2
from (select 'F/P/O' as val from dual) t

Here, by the way, is the SQL Fiddle.

Oops. I missed the part of the question where it says the last delimiter. For that, we can use regex_replace() for the first part:

select regexp_replace(val, '/[^/]+$', '', 1, 1) as part1,
       regexp_substr(val, '[^/]+$', 1, 1) as part2
from (select 'F/P/O' as val from dual) t

And here is this corresponding SQL Fiddle.

Something I did recently, hope it helps. I have a list of dictionaries and wanted to add a value to some existing documents.

for item in my_list:
    my_collection.update({"_id" : item[key] }, {"$set" : {"New_col_name" :item[value]}})

Change the node to and create a file, packages.xsd, in the same folder (and include it in the project) with the following contents:

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
      targetNamespace="urn:packages" xmlns="urn:packages">
  <xs:element name="packages">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="package" maxOccurs="unbounded">
          <xs:complexType>
            <xs:attribute name="id" type="xs:string" use="required" />
            <xs:attribute name="version" type="xs:string" use="required" />
            <xs:attribute name="targetFramework" type="xs:string" use="optional" />
            <xs:attribute name="allowedVersions" type="xs:string" use="optional" />
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

It seems you need DataFrame.var:

Normalized by N-1 by default. This can be changed using the ddof argument

var1 = credit_card.var()

Sample:

#random dataframe
np.random.seed(100)
credit_card = pd.DataFrame(np.random.randint(10, size=(5,5)), columns=list('ABCDE'))
print (credit_card)
   A  B  C  D  E
0  8  8  3  7  7
1  0  4  2  5  2
2  2  2  1  0  8
3  4  0  9  6  2
4  4  1  5  3  4

var1 = credit_card.var()
print (var1)
A     8.8
B    10.0
C    10.0
D     7.7
E     7.8
dtype: float64

var2 = credit_card.var(axis=1)
print (var2)
0     4.3
1     3.8
2     9.8
3    12.2
4     2.3
dtype: float64

If need numpy solutions with numpy.var:

print (np.var(credit_card.values, axis=0))
[ 7.04  8.    8.    6.16  6.24]

print (np.var(credit_card.values, axis=1))
[ 3.44  3.04  7.84  9.76  1.84]

Differences are because by default ddof=1 in pandas, but you can change it to 0:

var1 = credit_card.var(ddof=0)
print (var1)
A    7.04
B    8.00
C    8.00
D    6.16
E    6.24
dtype: float64

var2 = credit_card.var(ddof=0, axis=1)
print (var2)
0    3.44
1    3.04
2    7.84
3    9.76
4    1.84
dtype: float64

Android Studio Version 2.3

You can create a Service without a Main Activity by following a few easy steps. You'll be able to install this app through Android Studio and debug it like a normal app.

First, create a project in Android Studio without an activity. Then create your Service class and add the service to your AndroidManifest.xml

<application android:allowBackup="true"
    android:label="@string/app_name"
    android:icon="@mipmap/ic_launcher"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <service android:name="com.whatever.myservice.MyService">
        <intent-filter>
            <action android:name="com.whatever.myservice.MyService" />
        </intent-filter>
    </service>
</application>

Now, in the drop down next to the "Run" button(green arrow), go to "edit configurations" and within the "Launch Options" choose "Nothing". This will allow you to install your Service without Android Studio complaining about not having a Main Activity.

Once installed, the service will NOT be running but you will be able to start it with this adb shell command...

am startservice -n com.whatever.myservice/.MyService

Can check it's running with...

ps | grep whatever

I haven't tried yet but you can likely have Android Studio automatically start the service too. This would be done in that "Edit Configurations" menu.

Dimension table : It is nothing but we can maintains information about the characterized date called as Dimension table.

Example : Time Dimension , Product Dimension.

Fact Table : It is nothing but we can maintains information about the metrics or precalculation data.

Example : Sales Fact, Order Fact.

Star schema : one fact table link with dimension table form as a Start Schema.

Setting up log4j logging for Tomcat is pretty simple. The following is quoted from http://tomcat.apache.org/tomcat-5.5-doc/logging.html :

1. Create a file called log4j.properties with the following content and save it into common/classes.

             log4j.rootLogger=DEBUG, R 
             log4j.appender.R=org.apache.log4j.RollingFileAppender 
             log4j.appender.R.File=${catalina.home}/logs/tomcat.log 
             log4j.appender.R.MaxFileSize=10MB 
             log4j.appender.R.MaxBackupIndex=10 
             log4j.appender.R.layout=org.apache.log4j.PatternLayout 
             log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
   

2. Download Log4J (v1.2 or later) and place the log4j jar in $CATALINA_HOME/common/lib.

3. Download Commons Logging and place the commons-logging-x.y.z.jar (not commons-logging-api-x.y.z.jar) in $CATALINA_HOME/common/lib with the log4j jar.
4. Start Tomcat

squares = squarer(x)

Arithmetic operations on arrays are automatically applied elementwise, with efficient C-level loops that avoid all the interpreter overhead that would apply to a Python-level loop or comprehension.

Most of the functions you'd want to apply to a NumPy array elementwise will just work, though some may need changes. For example, if doesn't work elementwise. You'd want to convert those to use constructs like numpy.where:

def using_if(x):
    if x < 5:
        return x
    else:
        return x**2

becomes

def using_where(x):
    return numpy.where(x < 5, x, x**2)

Or you can cast your string to Date format with date function. Even the date is stored as TEXT in the DB. Like this (the most workable variant):

SELECT * FROM test WHERE date(date) 
BETWEEN date('2011-01-11') AND date('2011-8-11')

Your table is already locked by some query. For example, you may have executed "select for update" and have not yet committed/rollbacked and fired another select query. Do a commit/rollback before executing your query.

Alexander Abakumov's answer is the correct one. It solved every binding issue I had updating the underlying data and having the grid update.

Its easy to implement and modify any existing source code you have.

grdDetails.DataSource = new System.Windows.Forms.BindingSource { DataSource = OrderDetails };

Say you want Comic Sans for the title and Helvetica for the x label.

csfont = {'fontname':'Comic Sans MS'}
hfont = {'fontname':'Helvetica'}

plt.title('title',**csfont)
plt.xlabel('xlabel', **hfont)
plt.show()

You could also just use jQuery to remove the contents of the div that contains your svg.

$("#container_div_id").html("");

Check your namespaces. I had and issue with that. I found that out by adding another web service to the project to dup it like you did yours and noticed the namespace was different. I had renamed it at the beginning of the project and it looks like its persisted.

I faced the similar problem, and solved by django admin site.

# models
class Document(models.Model):
    docfile = models.FileField(upload_to='documents/Temp/%Y/%m/%d')

    def doc_name(self):
        return self.docfile.name.split('/')[-1] # only the name, not full path

# admin
from myapp.models import Document
class DocumentAdmin(admin.ModelAdmin):
    list_display = ('doc_name',)
admin.site.register(Document, DocumentAdmin)

Only justification for moving your application to 64 bit is need for more memory in applications like large databases or ERP applications with at least 100s of concurrent users where 2 GB limit will be exceeded fairly quickly when applications cache for better performance. This is case specially on Windows OS where integer and long is still 32 bit (they have new variable _int64. Only pointers are 64 bit. In fact WOW64 is highly optimised on Windows x64 so that 32 bit applications run with low penalty on 64 bit Windows OS. My experience on Windows x64 is 32 bit application version run 10-15% faster than 64 bit since in former case at least for proprietary memory databases you can use pointer arithmatic for maintaining b-tree (most processor intensive part of database systems). Compuatation intensive applications which require large decimals for highest accuracy not afforded by double on 32-64 bit operating system. These applications can use _int64 in natively instead of software emulation. Of course large disk based databases will also show improvement over 32 bit simply due to ability to use large memory for caching query plans and so on.

Typos are a possible reason for this error.

Be sure to check you wrote spring-boot and not e.g. springboot or sprint-boot or springbok or whatever.

Also check the ordering : use spring-boot:run and not run:spring-boot.

To go from SCRATCH with SQLite DB to importing the CSV into a table:

• Get SQLite from the website.
• At a command prompt run sqlite3 <your_db_file_name> *It will be created as an empty file.
• Make a new table in your new database. The table must match your CSV fields for import.
• You do this by the SQL command: CREATE TABLE <table_Name> (<field_name1> <Type>, <field_name2> <type>);

Once you have the table created and the columns match your data from the file then you can do the above...

.mode csv <table_name>
.import <filename> <table_name>

Try use the library : https://imapx.codeplex.com/

That library free, open source and have example at this : https://imapx.codeplex.com/wikipage?title=Sample%20code%20for%20get%20messages%20from%20your%20inbox

I believe you could addClass to the element. But either way you'd have to use Jquery or reg JS

div {
  opacity:0;
  transition:opacity 1s linear;*
}
div.SomeClass {
  opacity:1;
}

The field's value is:

 "- DE-HEB 20% - DTopTen 1.2%"
SELECT ....
SUBSTRING_INDEX(SUBSTRING_INDEX(DesctosAplicados, 'DE-HEB ',  -1), '-', 1) DE-HEB ,
SUBSTRING_INDEX(SUBSTRING_INDEX(DesctosAplicados, 'DTopTen ',  -1), '-', 1) DTopTen ,

FROM TABLA 

Result is:

  DE-HEB       DTopTEn
    20%          1.2%

Because it has already been pushed, you shouldn't directly manipulate history. git revert will revert specific changes from a commit using a new commit, so as to not manipulate commit history.

You just needed to cast the unsigned char into a char as the string class doesn't have a constructor that accepts unsigned char:

unsigned char* uc;
std::string s( reinterpret_cast< char const* >(uc) ) ;

However, you will need to use the length argument in the constructor if your byte array contains nulls, as if you don't, only part of the array will end up in the string (the array up to the first null)

size_t len;
unsigned char* uc;
std::string s( reinterpret_cast<char const*>(uc), len ) ;

To permanently set the language syntax:
open settings.json file

*) format all txt files with javascript formatting

"files.associations": {
        "*.txt": "javascript"

 }

*) format all unsaved files (untitled-1 etc) to javascript:

"files.associations": {
        "untitled-*": "javascript"

 }

You can use addBatch and executeBatch for batch insert in java See the Example : Batch Insert In Java

Believing this performance evaluation, the switch case is faster.

This is the conclusion:

The results show that the switch statement is faster to execute than the if-else-if ladder. This is due to the compiler's ability to optimise the switch statement. In the case of the if-else-if ladder, the code must process each if statement in the order determined by the programmer. However, because each case within a switch statement does not rely on earlier cases, the compiler is able to re-order the testing in such a way as to provide the fastest execution.

Building on Rick Viscomi's answer, try using the HTML Select Element's selectedOptions property:

let txtSelectedValuesObj = document.getElementById('txtSelectedValues');
[...txtSelectedValuesObj.selectedOptions].map(option => option.value);

In detail,

• selectedOptions returns a list of selected items.
• Specifically, it returns a read-only HTMLCollection containing HTMLOptionElements.
• ... is spread syntax. It expands the HTMLCollection's elements.
• [...] creates a mutable Array object from these elements, giving you an array of HTMLOptionElements.
• map() replaces each HTMLObjectElement in the array (here called option) with its value (option.value).

Dense, but it seems to work.

Watch out, selectedOptions isn't supported by IE!

The actual cause of this warning is that you have configured your project to run with an earlier JRE version then you have installed. Generally this occurs whenever you use old projects with newer JREs.

This will likely cause no trouble at all. But if you want to be really on the save side, you should install the correct, old JDK. You can find them here: http://www.oracle.com/technetwork/java/archive-139210.html

If you then restart eclipse you can go into Window > Preferences > Java > Installed JREs > Execution Environments and set for in your case J2SE-1.4 the [perfect match] as eclipse calls it.

We should be using --scan --pattern with redis 2.8 and later.

You can try using this wrapper on top of redis-cli. https://github.com/VijayantSoni/redis-helper

I've had to do something like this when using commons-httpclient to access an internal https server with a self-signed certificate. Yes, our solution was to create a custom TrustManager that simply passed everything (logging a debug message).

This comes down to having our own SSLSocketFactory that creates SSL sockets from our local SSLContext, which is set up to have only our local TrustManager associated with it. You don't need to go near a keystore/certstore at all.

So this is in our LocalSSLSocketFactory:

static {
    try {
        SSL_CONTEXT = SSLContext.getInstance("SSL");
        SSL_CONTEXT.init(null, new TrustManager[] { new LocalSSLTrustManager() }, null);
    } catch (NoSuchAlgorithmException e) {
        throw new RuntimeException("Unable to initialise SSL context", e);
    } catch (KeyManagementException e) {
        throw new RuntimeException("Unable to initialise SSL context", e);
    }
}

public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
    LOG.trace("createSocket(host => {}, port => {})", new Object[] { host, new Integer(port) });

    return SSL_CONTEXT.getSocketFactory().createSocket(host, port);
}

Along with other methods implementing SecureProtocolSocketFactory. LocalSSLTrustManager is the aforementioned dummy trust manager implementation.

SELECT [activity_dt], COUNT(*) as [Count]
  FROM

    FROM table) abc
 GROUP BY [activity_dt]

Note the comma in your string: "1,07". DecimalFormat uses a locale-specific separator string, while Double.parseDouble() does not. As you happen to live in a country where the decimal separator is ",", you can't parse your number back.

However, you can use the same DecimalFormat to parse it back:

DecimalFormat df=new DecimalFormat("0.00");
String formate = df.format(value); 
double finalValue = (Double)df.parse(formate) ;

But you really should do this instead:

double finalValue = Math.round( value * 100.0 ) / 100.0;

Note: As has been pointed out, you should only use floating point if you don't need a precise control over accuracy. (Financial calculations being the main example of when not to use them.)

The "protected internal" access modifier is a union of both the "protected" and "internal" modifiers.

From MSDN, Access Modifiers (C# Programming Guide):

protected:

The type or member can be accessed only by code in the same class or struct, or in a class that is derived from that class.

internal:

The type or member can be accessed by any code in the same assembly, but not from another assembly.

protected internal:

The type or member can be accessed by any code in the assembly in which it is declared, OR from within a derived class in another assembly. Access from another assembly must take place within a class declaration that derives from the class in which the protected internal element is declared, and it must take place through an instance of the derived class type.

Note that: protected internal means "protected OR internal" (any class in the same assembly, or any derived class - even if it is in a different assembly).

...and for completeness:

private:

The type or member can be accessed only by code in the same class or struct.

public:

The type or member can be accessed by any other code in the same assembly or another assembly that references it.

private protected:

Access is limited to the containing class or types derived from the containing class within the current assembly.

Use the FULL path to the folder in your If Not Exist code. Then you won't even have to CD anymore:

If Not Exist "C:\Documents and Settings\John\Start Menu\Programs\SoftWareFolder\"

Because os.path.abspath = os.path.dirname + os.path.basename does not hold. we rather have

os.path.dirname(filename) + os.path.basename(filename) == filename

Both dirname() and basename() only split the passed filename into components without taking into account the current directory. If you want to also consider the current directory, you have to do so explicitly.

To get the dirname of the absolute path, use

os.path.dirname(os.path.abspath(__file__))

i got the same problem, i used malloc over n over again in a loop for adding new char *string data. i faced the same problem, but after releasing the allocated memory void free() problem were sorted

Use getChildCount() and getChildAt(int index).

Example:

LinearLayout ll = …
final int childCount = ll.getChildCount();
for (int i = 0; i < childCount; i++) {
      View v = ll.getChildAt(i);
      // Do something with v.
      // …
}

To use this function/method,you need an instance of the class Date .

This method is always used in conjunction with a Date object.

See the code below :

var d = new Date();
d.getTime();

Place your text file in the /assets directory under the Android project. Use AssetManager class to access it.

AssetManager am = context.getAssets();
InputStream is = am.open("test.txt");

Or you can also put the file in the /res/raw directory, where the file will be indexed and is accessible by an id in the R file:

InputStream is = context.getResources().openRawResource(R.raw.test);

var isAlaCarte = 
    ConfigurationManager.AppSettings.AllKeys.Contains("IsALaCarte") && 
    bool.Parse(ConfigurationManager.AppSettings.Get("IsALaCarte"));

Windows 10 Solution:

For me this issue was due to downloading and creating an AVD using Android Studio and then trying to use that virtual device with the Ionic command line. I resolved this by deleting all existing emulators and creating a new one from the command line.

(the avdmanager file typically lives in C:\Users\\Android\sdk\tools\bin)

List existing emulators: avdmanager list avd

Delete an existing emulator: avdmanager delete avd -n emulator_name

Add system image: sdkmanager "system-images;android-24;default;x86_64"

Create new emulator: sdkmanager "system-images;android-27;google_apis_playstore;x86"

You have to keep in mind that Google encodes spaces as + To avoid this, the ulr must be encoded in RFC 3986, which means spaces encoded at %20, for example:

Say we want to remove commits 2 & 4 from the repo.

commit 0 : b3d92c5
commit 1 : 2c6a45b
commit 2 : <any_hash>
commit 3 : 77b9b82
commit 4 : <any_hash>

Note: You need to have admin rights over the repo since you are using --hard and -f.

• git checkout b3d92c5 Checkout the last usable commit.
• git checkout -b repair Create a new branch to work on.
• git cherry-pick 77b9b82 Run through commit 3.
• git cherry-pick 2c6a45b Run through commit 1.
• git checkout master Checkout master.
• git reset --hard b3d92c5 Reset master to last usable commit.
• git merge repair Merge our new branch onto master.
• git push -f origin master Push master to the remote repo.

You need to convert Array to string :

//arrayOfValues = [1, 2, 3];  
$.get('/controller/MyAction', { arrayOfValues: "1, 2, 3" }, function (data) {...

this works even in form of int, long or string

public ActionResult MyAction(int[] arrayOfValues )

I was trying to also sort by a DateTime field descending and this seems to do the trick:

var ud = (from d in env 
     orderby -d.ReportDate.Ticks                 
     select  d.ReportDate.ToString("yyyy-MMM") ).Distinct(); 

You can use all():

my_list1 = [30,34,56]
my_list2 = [29,500,43]
if all(i >= 30 for i in my_list1):
    print 'yes'
if all(i >= 30 for i in my_list2):
    print 'no'

Note that this includes all numbers equal to 30 or higher, not strictly above 30.

If your code is ES7 based (or upper versions):

channelArray.includes('three'); //will return true or false

If not, for example you are using IE with no babel transpile:

channelArray.indexOf('three') !== -1; //will return true or false

the indexOf method will return the position the element has into the array, because of that we use !== different from -1 if the needle is found at the first position.

If anybody needs light Swift extension to change UIView margins easily - you can use this

view.top = 16
view.right = self.width
view.bottom = self.height
self.height = view.bottom

To me this is just one of many idiosyncracies (emphasis on the idio(t) ) of typescript that causes people to pull out their hair and curse the developers. Maybe they could work on coming up with more understandable error messages.

LEFT ('BTA200', 3) will work for the examples you have given, as in :

SELECT LEFT(MyField, 3)
FROM MyTable

To extract the numeric part, you can use this code

SELECT RIGHT(MyField, LEN(MyField) - 3)
FROM MyTable
WHERE MyField LIKE 'BTA%' 
--Only have this test if your data does not always start with BTA.

I started down this path because ESXi's wget is not compiled with SSL and I wanted to download an OVA from a vendor's website directly onto the ESXi host which is on the other side of the world.

I had to disable the firewall(lazy)/enable https out by editing the rules(proper)

created the python script:

import ssl
import shutil
import tempfile
import urllib.request
context = ssl._create_unverified_context()

dlurl='https://somesite/path/whatever'
with urllib.request.urlopen(durl, context=context) as response:
    with open("file.ova", 'wb') as tmp_file:
        shutil.copyfileobj(response, tmp_file)

ESXi libraries are kind of paired down but the open source weasel installer seemed to use urllib for https... so it inspired me to go down this path

Here is a core JavaScript function to wait for the display of an element (well, its insertion into the DOM to be more accurate).

// Call the below function
waitForElementToDisplay("#div1",function(){alert("Hi");},1000,9000);

function waitForElementToDisplay(selector, callback, checkFrequencyInMs, timeoutInMs) {
  var startTimeInMs = Date.now();
  (function loopSearch() {
    if (document.querySelector(selector) != null) {
      callback();
      return;
    }
    else {
      setTimeout(function () {
        if (timeoutInMs && Date.now() - startTimeInMs > timeoutInMs)
          return;
        loopSearch();
      }, checkFrequencyInMs);
    }
  })();
}

This call will look for the HTML tag whose id="div1" every 1000 milliseconds. If the element is found, it will display an alert message Hi. If no element is found after 9000 milliseconds, this function stops its execution.

Parameters:

1. selector: String : This function looks for the element ${selector}.
2. callback: Function : This is a function that will be called if the element is found.
3. checkFrequencyInMs: Number : This function checks whether this element exists every ${checkFrequencyInMs} milliseconds.
4. timeoutInMs : Number : Optional. This function stops looking for the element after ${timeoutInMs} milliseconds.

NB : Selectors are explained at https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector

tl;dr

LocalDate                       // Represents an entire day, without time-of-day and without time zone.
.now(                           // Capture the current date.
    ZoneId.of( "Asia/Tokyo" )   // Returns a `ZoneId` object.
)                               // Returns a `LocalDate` object.
.atStartOfDay(                  // Determines the first moment of the day as seen on that date in that time zone. Not all days start at 00:00!
    ZoneId.of( "Asia/Tokyo" ) 
)                               // Returns a `ZonedDateTime` object.

Start of day

Get the full length of the today as seen in a time zone.

Using Half-Open approach, where the beginning is inclusive while the ending is exclusive. This approach solves the flaw in your code that fails to account for the very last second of the day.

ZoneId zoneId = ZoneId.of( "Africa/Tunis" ) ;
LocalDate today = LocalDate.now( zoneId  ) ;

ZonedDateTime zdtStart = today.atStartOfDay( zoneId ) ;
ZonedDateTime zdtStop = today.plusDays( 1 ).atStartOfDay( zoneId ) ;

zdtStart.toString() = 2020-01-30T00:00+01:00[Africa/Tunis]

zdtStop.toString() = 2020-01-31T00:00+01:00[Africa/Tunis]

See the same moments in UTC.

Instant start = zdtStart.toInstant() ;
Instant stop = zdtStop.toInstant() ;

start.toString() = 2020-01-29T23:00:00Z

stop.toString() = 2020-01-30T23:00:00Z

If you want the entire day of a date as seen in UTC rather than in a time zone, use OffsetDateTime.

LocalDate today = LocalDate.now( ZoneOffset.UTC  ) ;

OffsetDateTime odtStart = today.atTime( OffsetTime.MIN ) ;
OffsetDateTime odtStop = today.plusDays( 1 ).atTime( OffsetTime.MIN ) ;

odtStart.toString() = 2020-01-30T00:00+18:00

odtStop.toString() = 2020-01-31T00:00+18:00

These OffsetDateTime objects will already be in UTC, but you can call toInstant if you need such objects which are always in UTC by definition.

Instant start = odtStart.toInstant() ;
Instant stop = odtStop.toInstant() ;

start.toString() = 2020-01-29T06:00:00Z

stop.toString() = 2020-01-30T06:00:00Z

Tip: You may be interested in adding the ThreeTen-Extra library to your project to use its Interval class to represent this pair of Instant objects. This class offers useful methods for comparison such as abuts, overlaps, contains, and more.

Interval interval = Interval.of( start , stop ) ;

interval.toString() = 2020-01-29T06:00:00Z/2020-01-30T06:00:00Z

Half-Open

The answer by mprivat is correct. His point is to not try to obtain end of a day, but rather compare to "before start of next day". His idea is known as the "Half-Open" approach where a span of time has a beginning that is inclusive while the ending is exclusive.

• The current date-time frameworks of Java (java.util.Date/Calendar and Joda-Time) both use milliseconds from the epoch. But in Java 8, the new JSR 310 java.time.* classes use nanoseconds resolution. Any code you wrote based on forcing the milliseconds count of last moment of day would be incorrect if switched to the new classes.
• Comparing data from other sources becomes faulty if they employ other resolutions. For example, Unix libraries typically employ whole seconds, and databases such as Postgres resolve date-time to microseconds.
• Some Daylight Saving Time changes happen over midnight which might further confuse things.

Joda-Time 2.3 offers a method for this very purpose, to obtain first moment of the day: withTimeAtStartOfDay(). Similarly in java.time, LocalDate::atStartOfDay.

Search StackOverflow for "joda half-open" to see more discussion and examples.

See this post, Time intervals and other ranges should be half-open, by Bill Schneider.

Avoid legacy date-time classes

The java.util.Date and .Calendar classes are notoriously troublesome. Avoid them.

Use java.time classes. The java.time framework is the official successor of the highly successful Joda-Time library.

java.time

The java.time framework is built into Java 8 and later. Back-ported to Java 6 & 7 in the ThreeTen-Backport project, further adapted to Android in the ThreeTenABP project.

An Instant is a moment on the timeline in UTC with a resolution of nanoseconds.

Instant instant = Instant.now();

Apply a time zone to get the wall-clock time for some locality.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

To get the first moment of the day go through the LocalDate class and its atStartOfDay method.

ZonedDateTime zdtStart = zdt.toLocalDate().atStartOfDay( zoneId );

Using Half-Open approach, get first moment of following day.

ZonedDateTime zdtTomorrowStart = zdtStart.plusDays( 1 );

Currently the java.time framework lacks an Interval class as described below for Joda-Time. However, the ThreeTen-Extra project extends java.time with additional classes. This project is the proving ground for possible future additions to java.time. Among its classes is Interval. Construct an Interval by passing a pair of Instant objects. We can extract an Instant from our ZonedDateTime objects.

Interval today = Interval.of( zdtStart.toInstant() , zdtTomorrowStart.toInstant() );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 brought some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

Joda-Time

UPDATE: The Joda-Time project is now in maintenance-mode, and advises migration to the java.time classes. I am leaving this section intact for history.

Joda-Time has three classes to represent a span of time in various ways: Interval, Period, and Duration. An Interval has a specific beginning and ending on the timeline of the Universe. This fits our need to represent "a day".

We call the method withTimeAtStartOfDay rather than set time of day to zeros. Because of Daylight Saving Time and other anomalies the first moment of the day may not be 00:00:00.

Example code using Joda-Time 2.3.

DateTimeZone timeZone = DateTimeZone.forID( "America/Montreal" );
DateTime now = DateTime.now( timeZone );
DateTime todayStart = now.withTimeAtStartOfDay();
DateTime tomorrowStart = now.plusDays( 1 ).withTimeAtStartOfDay();
Interval today = new Interval( todayStart, tomorrowStart );

If you must, you can convert to a java.util.Date.

java.util.Date date = todayStart.toDate();

try this query to have sepratley count of each SELECT statements :

select field1,count(field1) as field1Count,field2,count(field2) as field2Counts,field3, count(field3) as field3Counts
from table_name
group by field1,field2,field3
having count(*) > 1

IMO, implementation #1 is typical and being short and idiomatic for Perl trumps the others for that alone. A benchmark of the three choices might offer you insight into speed, at least.

You can use the combinat package with R 2.13:

install.packages("combinat")
require(combinat)
permn(3)
combn(3, 2)

If you want to know the number of combination/permutations, then check the size of the result, e.g.:

length(permn(3))
dim(combn(3,2))[2]

None of the solution are working currently. Here is my solution. You can add prefixes.

box-shadow: inset 0px 0px 0px 0px red;

I was trying to run pg_dump from within psql command prompt and I was not able to trace output file anywhere on my ubuntu 20.04 box. I tried finding by find / -name "myfilename.sql".

You should never look to override certificate validation in code! If you need to do testing, use an internal/test CA and install the CA root certificate on the device or emulator. You can use BurpSuite or Charles Proxy if you don't know how to setup a CA.

The content is not ready yet, you can move your js to the end of the file or do

<script>
$(function () { 
    $( '.expand' ).click(function() {
       $( '.img_display_content' ).show();
    });
});

So that the document waits to be loaded before running.

use my_list.append(...) and do not use and other list to append as list are mutable.

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

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

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

You are supposed to be able to specify a domain that is safe for scripting. the api document mentions "As an extra security measure, you should also include the origin parameter to the URL" http://code.google.com/apis/youtube/iframe_api_reference.html src="http://www.youtube.com/embed/J---aiyznGQ?enablejsapi=1&origin=mydomain.com" would be the src of your iframe.

however it is not very well documented. I am trying something similar right now.

This type of code create problem while porting.

The correct implementation in Prototype should look like this:

var obj1 = {food: 'pizza', car: 'ford'}
var obj2 = {animal: 'dog'}

obj1 = Object.extend(obj1, obj2);

This might be extremely convoluted and I might be missing the obvious, but without OpenPyXL filling in the column_dimensions in Iterable Worksheets (see my comment above), the only way I can see of finding the column size without loading everything is to parse the xml directly:

from xml.etree.ElementTree import iterparse
from openpyxl import load_workbook
wb=load_workbook("/path/to/workbook.xlsx", use_iterators=True)
ws=wb.worksheets[0]
xml = ws._xml_source
xml.seek(0)

for _,x in iterparse(xml):

    name= x.tag.split("}")[-1]
    if name=="col":
        print "Column %(max)s: Width: %(width)s"%x.attrib # width = x.attrib["width"]

    if name=="cols":
        print "break before reading the rest of the file"
        break

Add the following environment variable:

NODE_TLS_REJECT_UNAUTHORIZED=0

e.g. with export:

export NODE_TLS_REJECT_UNAUTHORIZED=0

I know the question explicitly says JS or jQuery, but anyway using lodash is always on the table for other searchers I suppose.

From the source docs:

var users = [
  { 'user': 'barney', 'age': 36, 'active': true },
  { 'user': 'fred',   'age': 40, 'active': false }
];

_.filter(users, function(o) { return !o.active; });
// => objects for ['fred']

// The `_.matches` iteratee shorthand.
_.filter(users, { 'age': 36, 'active': true });
// => objects for ['barney']

// The `_.matchesProperty` iteratee shorthand.
_.filter(users, ['active', false]);
// => objects for ['fred']

// The `_.property` iteratee shorthand.
_.filter(users, 'active');
// => objects for ['barney']

So the solution for the original question would be just one liner:

var result = _.filter(data, ['website', 'yahoo']);

Put breakpoints - double click on the margin. Run > Debug > Yes (if dialog appears), then use commands from Run menu or shortcuts - F5, F6, F7, F8.

You would expect that this is easily possible but that seems not be the case. The only way I see at the moment is to create a user defined JQL function. I never tried this but here is a plug-in:

The same origin policy is applicable only for browser side programming languages. So if you try to post to a different server than the origin server using JavaScript, then the same origin policy comes into play but if you post directly from the form i.e. the action points to a different server like:

<form action="http://someotherserver.com">

and there is no javascript involved in posting the form, then the same origin policy is not applicable.

See wikipedia for more information

You don't add columns between other columns in SQL, you just add them. Where they're put is totally up to the DBMS. The right place to ensure that columns come out in the correct order is when you select them.

In other words, if you want them in the order {name,colnew,qty,rate}, you use:

select name, colnew, qty, rate from ...

With SQLite, you need to use alter table, an example being:

alter table mytable add column colnew char(50)

You cannot style things like radio buttons, checkboxes, scrollsbars (etc.) at all. These are native to the OS and the browser and not something you can manipulate.

You can simulate this, however by hiding the radio buttons and only showing an image instead as in.

<input type="radio" style="display: none;" id="sad" /><label for="sad"><img class="sad_image" /></label>

Your server's response allows the request to include three specific non-simple headers:

Access-Control-Allow-Headers:origin, x-requested-with, content-type

but your request has a header not allowed by the server's response:

Access-Control-Request-Headers:access-control-allow-origin, content-type

All non-simple headers sent in a CORS request must be explicitly allowed by the Access-Control-Allow-Headers response header. The unnecessary Access-Control-Allow-Origin header sent in your request is not allowed by the server's CORS response. This is exactly what the "...not allowed by Access-Control-Allow-Headers" error message was trying to tell you.

There is no reason for the request to have this header: it does nothing, because Access-Control-Allow-Origin is a response header, not a request header.

Solution: Remove the setRequestHeader call that adds a Access-Control-Allow-Origin header to your request.

Unlike jQuery in order to read raw JSON you will need to decode it in PHP.

print_r(json_decode(file_get_contents("php://input"), true));

php://input is a read-only stream that allows you to read raw data from the request body.

$_POST is form variables, you will need to switch to form radiobutton in postman then use:

foo=bar&foo2=bar2

To post raw json with jquery:

$.ajax({
    "url": "/rest/index.php",
    'data': JSON.stringify({foo:'bar'}),
    'type': 'POST',
    'contentType': 'application/json'
});

There are several methods, two of which are as follows. Provide a custom installer or a setup project.

Here is how to create a custom installer

[RunInstaller(true)]
public class MyInstaller : Installer
{
    public HelloInstaller()
        : base()
    {
    }

    public override void Commit(IDictionary mySavedState)
    {
        base.Commit(mySavedState);
        System.IO.File.CreateText("Commit.txt");
    }

    public override void Install(IDictionary stateSaver)
    {
        base.Install(stateSaver);
        System.IO.File.CreateText("Install.txt");
    }

    public override void Uninstall(IDictionary savedState)
    {
        base.Uninstall(savedState);
        File.Delete("Commit.txt");
        File.Delete("Install.txt");
    }

    public override void Rollback(IDictionary savedState)
    {
        base.Rollback(savedState);
        File.Delete("Install.txt");
    }
}

To add a setup project

• Menu file -> New -> Project --> Other Projects Types --> Setup and Deployment

• Set properties of the project, using the properties window

The article How to create a Setup package by using Visual Studio .NET provides the details.

Try this one -

DECLARE @i FLOAT = 6.677756

    , SUBSTRING(PARSENAME(CAST(@i AS VARCHAR(10)), 1), PATINDEX('%.%', CAST(@i AS VARCHAR(10))) - 1, 2)
    , FLOOR((@i - FLOOR(@i)) * 100)

I get the same error in Chrome after pasting code copied from jsfiddle.

If you select all the code from a panel in jsfiddle and paste it into the free text editor Notepad++, you should be able to see the problem character as a question mark "?" at the very end of your code. Delete this question mark, then copy and paste the code from Notepad++ and the problem will be gone.

I had the same problem but I solved in other way (becouse at right click on project folder no Maven tab apears only if I do that on pom.xml I can see a Maven tab):

So I tink that you get that error because the IDE (Eclipse) didn`t import the dependecies from Maven. Since you are using Spring framework and you probably have STS allready installed right-click on project folder Spring Tools -> Update Maven Dependecies.

I`m using Eclipse JUNO m2eclipse 1.3.0 Spring IDEE 3.1

lookup only works on localhost. If you want to retrieve variables from a variables file you made remotely use include_vars: {{ varfile }} . Contents of {{ varfile }} should be a dictionary of the form {"key":"value"}, you will find ansible gives you trouble if you include a space after the colon.

I think your issue may be in the url pattern. Changing

<servlet-mapping>
    <servlet-name>Register</servlet-name>
    <url-pattern>/Register</url-pattern>
</servlet-mapping>

and

<form action="/Register" method="post">

may fix your problem

Simple soultion : Import the HttpModule and HttpClientModule on your app.module.ts

**

import { HttpClientModule } from '@angular/common/http';
import { HttpModule } from '@angular/http';



@NgModule({
 declarations: [
   AppComponent, videoComponent, tagDirective, 
 ],
 imports: [
  BrowserModule, routing, HttpClientModule, HttpModule

],
providers: [ApiServices],
bootstrap: [AppComponent]
})
export class AppModule { }

This is probably not the main reason why the create_all() method call doesn't work for people, but for me, the cobbled together instructions from various tutorials have it such that I was creating my db in a request context, meaning I have something like:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

def get_db():
  if 'db' not in g:
    g.db = SQLAlchemy(current_app)
  return g.db

I also have a separate cli command that also does the create_all:

# tasks/db.py
from lib.db import get_db

@current_app.cli.command('init-db')
def init_db():
  db = get_db()
  db.create_all()

I also am using a application factory.

When the cli command is run, a new app context is used, which means a new db is used. Furthermore, in this world, an import model in the init_db method does not do anything, because it may be that your model file was already loaded(and associated with a separate db).

The fix that I came around to was to make sure that the db was a single global reference:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

db = None
def get_db():
  global db
  if not db:
    db = SQLAlchemy(current_app)
  return db

I have not dug deep enough into flask, sqlalchemy, or flask-sqlalchemy to understand if this means that requests to the db from multiple threads are safe, but if you're reading this you're likely stuck in the baby stages of understanding these concepts too.

You can also use

SELECT @curRow := ifnull(@curRow,0) + 1 Row, ...

to initialise the counter variable.

You should use $(document). It is a function trigger for any click event in the document. Then inside you can use the jquery on("click","body *",somefunction), where the second argument specifies which specific element to target. In this case every element inside the body.

$(document).on('click','body *',function(){
    //  $(this) = your current element that clicked.
    // additional code
});

Just remove or delete the server from eclipse and reconfigure it or add it again to Eclipse.

Batch files don't work that way. They don't just "type" everything - they run system commands, in this case ftp, wait for them to return, and run the next command... so in this case, the interpreter is simply waiting for ftp to exit.

If you must use the ftp command, then prepare a script file (for example, commands.txt and run ftp -s:commands.txt.

But using cURL, or a PHP/Perl/Python/whatever script may be a better idea.

ExecuteNonQuery():

1. will work with Action Queries only (Create,Alter,Drop,Insert,Update,Delete).
2. Returns the count of rows effected by the Query.
3. Return type is int
4. Return value is optional and can be assigned to an integer variable.

ExecuteReader():

1. will work with Action and Non-Action Queries (Select)
2. Returns the collection of rows selected by the Query.
3. Return type is DataReader.
4. Return value is compulsory and should be assigned to an another object DataReader.

ExecuteScalar():

1. will work with Non-Action Queries that contain aggregate functions.
2. Return the first row and first column value of the query result.
3. Return type is object.
4. Return value is compulsory and should be assigned to a variable of required type.

Here was my solution:

In the constructors add these two lines:

this.BackColor = Color.LimeGreen;
this.TransparencyKey = Color.LimeGreen;

In your form, add this method:

protected override void OnPaintBackground(PaintEventArgs e)
{
    e.Graphics.FillRectangle(Brushes.LimeGreen, e.ClipRectangle);
}

Be warned, not only is this form fully transparent inside the frame, but you can also click through it. However, it might be cool to draw an image onto it and make the form able to be dragged everywhere to create a custom shaped form.

You can add/remove Appender programmatically to Log4j:

  ConsoleAppender console = new ConsoleAppender(); //create appender
  //configure the appender
  String PATTERN = "%d [%p|%c|%C{1}] %m%n";
  console.setLayout(new PatternLayout(PATTERN)); 
  console.setThreshold(Level.FATAL);
  console.activateOptions();
  //add appender to any Logger (here is root)
  Logger.getRootLogger().addAppender(console);

  FileAppender fa = new FileAppender();
  fa.setName("FileLogger");
  fa.setFile("mylog.log");
  fa.setLayout(new PatternLayout("%d %-5p [%c{1}] %m%n"));
  fa.setThreshold(Level.DEBUG);
  fa.setAppend(true);
  fa.activateOptions();

  //add appender to any Logger (here is root)
  Logger.getRootLogger().addAppender(fa);
  //repeat with all other desired appenders

I'd suggest you put it into an init() somewhere, where you are sure, that this will be executed before anything else. You can then remove all existing appenders on the root logger with

 Logger.getRootLogger().getLoggerRepository().resetConfiguration();

and start with adding your own. You need log4j in the classpath of course for this to work.

Remark:
You can take any Logger.getLogger(...) you like to add appenders. I just took the root logger because it is at the bottom of all things and will handle everything that is passed through other appenders in other categories (unless configured otherwise by setting the additivity flag).

If you need to know how logging works and how is decided where logs are written read this manual for more infos about that.
In Short:

  Logger fizz = LoggerFactory.getLogger("com.fizz")

will give you a logger for the category "com.fizz".
For the above example this means that everything logged with it will be referred to the console and file appender on the root logger.
If you add an appender to Logger.getLogger("com.fizz").addAppender(newAppender) then logging from fizz will be handled by alle the appenders from the root logger and the newAppender.
You don't create Loggers with the configuration, you just provide handlers for all possible categories in your system.

If you want to ONLY count the documents with sent_at defined with a value of null (don't count the documents with sent_at not set):

db.emails.count({sent_at: { $type: 10 }})

When programming I often have strings with just plain A-Za-z and 0-9. No need for difficult Index actions. This extension is based on the plain old left / mid / right functions.

extension String {

    // LEFT
    // Returns the specified number of chars from the left of the string
    // let str = "Hello"
    // print(str.left(3))         // Hel
    func left(_ to: Int) -> String {
        return "\(self[..<self.index(startIndex, offsetBy: to)])"
    }

    // RIGHT
    // Returns the specified number of chars from the right of the string
    // let str = "Hello"
    // print(str.left(3))         // llo
    func right(_ from: Int) -> String {
        return "\(self[self.index(startIndex, offsetBy: self.length-from)...])"
    }

    // MID
    // Returns the specified number of chars from the startpoint of the string
    // let str = "Hello"
    // print(str.left(2,amount: 2))         // ll
    func mid(_ from: Int, amount: Int) -> String {
        let x = "\(self[self.index(startIndex, offsetBy: from)...])"
        return x.left(amount)
    }
}

Check this: How Do I Force the Browser to Use the Newest Version of my Stylesheet?

Assumming your css file is foo.css, you can force the client to use the latest version by appending a query string as shown below.

<link rel="stylesheet" href="foo.css?v=1.1">

Be careful using

SET sql_mode = '' 

This actually clears all the modes currently enabled. If you don't want to mess with other settings, you'll want to do a

SELECT @@sql_mode 

first, to get a comma-separated list of the modes enabled, then SET it to this list without the ONLY_FULL_GROUP_BY option.

1. To convert and append an integer, use operator += (or member function concat):

   String stringOne = "A long integer: ";
   stringOne += 123456789;
   

2. To get the string as type char[], use toCharArray():

   char charBuf[50];
   stringOne.toCharArray(charBuf, 50)
   

In the example, there is only space for 49 characters (presuming it is terminated by null). You may want to make the size dynamic.

Overhead

The cost of bringing in String (it is not included if not used anywhere in the sketch), is approximately 1212 bytes program memory (flash) and 48 bytes RAM.

This was measured using Arduino IDE version 1.8.10 (2019-09-13) for an Arduino Leonardo sketch.

The tutorial you saw was telling you how to exit nano editor. By typing Ctrl+X nano exits and if your file needs change you will be prompted to save the changes in which case to save you should press Y and then enter to save changes in the same file you open.

If you are not using any gui and you just want to leave the shell the command is Ctrl+D.

Regarding tutorial, The Linux Documentation Project would be a good place to start. If you like books I would recommend by far any book you want from O'Reilly. They have nice cd bookshelfs with good compilation for any linux sysadmin, and without much effort you can find many places where those html bookshelfs are available to read online.

Suppose we haven't used the "@" operator then our code would look like this:

$fileHandle = fopen($fileName, $writeAttributes);

And what if the file we are trying to open is not found? It will show an error message.

To suppress the error message we are using the "@" operator like:

$fileHandle = @fopen($fileName, $writeAttributes);

I used these css properties for line ellipsis-

overflow: hidden;
text-overflow: ellipsis;
display: -webkit-box;

here -webkit-line-clamp: 3; is the number of line(3 lines) after which ... shows.

That's part of the syntax of the new lambda expressions, to be introduced in Java 8. There are a couple of online tutorials to get the hang of it, here's a link to one. Basically, the -> separates the parameters (left-side) from the implementation (right side).

The general syntax for using lambda expressions is

(Parameters) -> { Body } where the -> separates parameters and lambda expression body.

The parameters are enclosed in parentheses which is the same way as for methods and the lambda expression body is a block of code enclosed in braces.

There is only a simple way to find modulo of 2^i numbers using bitwise.

There is an ingenious way to solve Mersenne cases as per the link such as n % 3, n % 7... There are special cases for n % 5, n % 255, and composite cases such as n % 6.

For cases 2^i, ( 2, 4, 8, 16 ...)

n % 2^i = n & (2^i - 1)

More complicated ones are hard to explain. Read up only if you are very curious.

If you set the style table-layout: fixed; on your table, you can override the browser's automatic column resizing. The browser will then set column widths based on the width of cells in the first row of the table. Change your <thead> to <caption> and remove the <td> inside of it, and then set fixed widths for the cells in <tbody>.

The best answer here is to use all(), which is the builtin for this situation. We combine this with a generator expression to produce the result you want cleanly and efficiently. For example:

>>> items = [[1, 2, 0], [1, 2, 0], [1, 2, 0]]
>>> all(flag == 0 for (_, _, flag) in items)
True
>>> items = [[1, 2, 0], [1, 2, 1], [1, 2, 0]]
>>> all(flag == 0 for (_, _, flag) in items)
False

Note that all(flag == 0 for (_, _, flag) in items) is directly equivalent to all(item[2] == 0 for item in items), it's just a little nicer to read in this case.

And, for the filter example, a list comprehension (of course, you could use a generator expression where appropriate):

>>> [x for x in items if x[2] == 0]
[[1, 2, 0], [1, 2, 0]]

If you want to check at least one element is 0, the better option is to use any() which is more readable:

>>> any(flag == 0 for (_, _, flag) in items)
True

A good way to sort on many fields that are strings is to use toLocaleCompare and the boolean operator ||.

Something like:

// Sorting record releases by name and then by title.
releases.sort((oldRelease, newRelease) => {
  const compareName = oldRelease.name.localeCompare(newRelease.name);
  const compareTitle = oldRelease.title.localeCompare(newRelease.title);

  return compareName || compareTitle;
})

If you wanted to sort on more fields, you could simply chain them off the return statement with more boolean operators.

chart.js supports this by defaul check the link. chartjs

you can set the label in the options attribute.

options object looks like this.

options = {
            scales: {
                yAxes: [
                    {
                        id: 'y-axis-1',
                        display: true,
                        position: 'left',
                        ticks: {
                            callback: function(value, index, values) {
                                return value + "%";
                            }
                        },
                        scaleLabel:{
                            display: true,
                            labelString: 'Average Personal Income',
                            fontColor: "#546372"
                        }
                    }   
                ]
            }
        };

First of all, create a Github account and project in Github. Go to the root folder and follow steps.

The most important thing we forgot here is ignoring the file. Every time we run Gradle or build it creates new files that are changeable from build to build and pc to pc. We do not want all the files from Android Studio to be added to Git. Files like generated code, binary files (executables) should not be added to Git (version control). So please use .gitignore file while uploading projects to Github. It also reduces the size of the project uploaded to the server.

1. Go to root folder.
2. git init

3. Create .gitignore txt file in root folder. Place these content in the file. (this step not required if the file is auto-generated)

   *.iml .gradle /local.properties /.idea/workspace.xml /.idea/libraries .idea .DS_Store /build /captures .externalNativeBuild

4. git add .
5. git remote add origin https://github.com/username/project.git
6. git commit - m "My First Commit"
7. git push -u origin master

Note : As per suggestion from different developers, they always suggest to use git from the command line. It is up to you.

The source code for the Android mobile application open-gpstracker which you appreciated is available here.

You can checkout the code using SVN client application or via Git:

• svn checkout http://open-gpstracker.googlecode.com/svn/trunk/ open-gpstracker-read-only
• git clone https://code.google.com/p/open-gpstracker/

Debugging the source code will surely help you.

It basically means that the application wants to perform some "naming operations" (e.g. JNDI or LDAP lookups), and it didn't have sufficient information available to be able to create a connection to the directory server. As the docs for the exception state,

This exception is thrown when no initial context implementation can be created. The policy of how an initial context implementation is selected is described in the documentation of the InitialContext class.

And if you dutifully have a look at the javadocs for InitialContext, they describe quite well how the initial context is constructed, and what your options are for supplying the address/credentials/etc.

If you have a go at creating the context and get stuck somewhere else, please post back explaining what you've done so far and where you're running aground.

The dialect in the Hibernate context, will take care of database data type, like in orace it is integer however in SQL it is int, so this will by known in hibernate by this property, how to map the fields internally.

Click on the WAMP server icon and from the menu under Config Files select httpd.conf. A long text file will open up in notepad. In this file scroll down to the line that reads Port 80 and change this to read Port 8080, Save the file and close notepad. Once again click on the wamp server icon and select restart all services. One more change needs to be made before we are done. In Windows Explorer find the location where WAMP server was installed which is by Default C:\Wamp.

Update : On a newer version of WAMP, click the WAMP server icon > Apache > httpd.conf, then change the line Listen 80 to Listen 8080 or any port you want.

Update: On 3.1.6 version of WAMP , right click on the wamp server icon in the taskbar ,select "tools"-> "Port used by Apache:80" -> "use a port other than 80", an input box will pop up , input a new port in it,click confirm button , then restart wamp .

I then call SQL*Plus passing the actual SQL script I want to run as an argument:

The result is written to a file

The quoting rules are painful. I think you want:

SELECT nextval('foo."SQ_ID"');

to prevent case-folding of SQ_ID.

If you use XHTML, for some reason, note that XHTML 1.0 C 4 says: “Use external scripts if your script uses < or & or ]]> or --.” That is, don’t embed script code inside a script element but put it into a separate JavaScript file and refer to it with <script src="foo.js"></script>.

In Convert.ToString(), the Convert handles either a NULL value or not but in .ToString() it does not handles a NULL value and a NULL reference exception error. So it is in good practice to use Convert.ToString().

I would recommend that you don't. Do you really want to have a class that is dependent on how the text editing is implemented in the form, or do you want a mechanism allowing you to get and set the text?

I would suggest the latter. So in your form, create a property that wraps the Text property of the TextBox control in question:

public string FirstName
{
    get { return firstNameTextBox.Text; }
    set { firstNameTextBox.Text = value; }
}

Next, create some mechanism through which you class can get a reference to the form (through the contructor for instance). Then that class can use the property to access and modify the text:

class SomeClass
{
    private readonly YourFormClass form;
    public SomeClass(YourFormClass form)
    {
        this.form = form;
    }

    private void SomeMethodDoingStuffWithText()
    {
        string firstName = form.FirstName;
        form.FirstName = "some name";
    }
}

An even better solution would be to define the possible interactions in an interface, and let that interface be the contract between your form and the other class. That way the class is completely decoupled from the form, and can use anyting implementing the interface (which opens the door for far easier testing):

interface IYourForm
{
    string FirstName { get; set; }
}

In your form class:

class YourFormClass : Form, IYourForm
{
    // lots of other code here

    public string FirstName
    {
        get { return firstNameTextBox.Text; }
        set { firstNameTextBox.Text = value; }
    }
}

...and the class:

class SomeClass
{
    private readonly IYourForm form;
    public SomeClass(IYourForm form)
    {
        this.form = form;
    }

    // and so on

}

I had the same problem in my code. I was concatenating a string to create a string. Below is the part of code.

int scannerId = 1;
std:strring testValue;
strInXml = std::string(std::string("<inArgs>" \
                        "<scannerID>" + scannerId) + std::string("</scannerID>" \
                        "<cmdArgs>" \
                        "<arg-string>" + testValue) + "</arg-string>" \
                        "<arg-bool>FALSE</arg-bool>" \
                        "<arg-bool>FALSE</arg-bool>" \
                        "</cmdArgs>"\
                        "</inArgs>");

Same issue here using IDEA 15.0.6, and nothing helped except when I renamed the package the test class was in. Afterwards I renamed it back to its original name and it still worked, so the rename action might have cleared some cache.

Don't be so verbose. It's Javascript. Use a Naming Convention.

After years of working in es6 classes, I recently started work on an es5 project (using requireJS which is already very verbose-looking). I've been over and over all the strategies mentioned here and it all basically boils down to use a naming convention:

1. Javascript doesn't have scope keywords like private. Other developers entering Javascript will know this upfront. Therefore, a simple naming convention is more than sufficient. A simple naming convention of prefixing with an underscore solves the problem of both private properties and private methods.
2. Let's take advantage of the Prototype for speed reasons, but lets not get anymore verbose than that. Let's try to keep the es5 "class" looking as closely to what we might expect in other backend languages (and treat every file as a class, even if we don't need to return an instance).
3. Let's demonstrate with a more realistic module situation (we'll use old es5 and old requireJs).

my-tooltip.js

    define([
        'tooltip'
    ],
    function(
        tooltip
    ){

        function MyTooltip() {
            // Later, if needed, we can remove the underscore on some
            // of these (make public) and allow clients of our class
            // to set them.
            this._selector = "#my-tooltip"
            this._template = 'Hello from inside my tooltip!';
            this._initTooltip();
        }

        MyTooltip.prototype = {
            constructor: MyTooltip,

            _initTooltip: function () {
                new tooltip.tooltip(this._selector, {
                    content: this._template,
                    closeOnClick: true,
                    closeButton: true
                });
            }
        }

        return {
            init: function init() {
               new MyTooltip();  // <-- Our constructor adds our tooltip to the DOM so not much we need to do after instantiation.
            }

            // You could instead return a new instantiation, 
            // if later you do more with this class.
            /* 
            create: function create() {
               return new MyTooltip();
            }
            */
        }
    });

I have used componentDidUpdate() in highchart.

Here is a simple example of this component.

import React, { PropTypes, Component } from 'react';
window.Highcharts = require('highcharts');

export default class Chartline extends React.Component {
  constructor(props) {
    super(props);
    this.state = {

    if (this.props.category) {
      const category = this.props.category ? this.props.category : {};
      console.log('category', category);
      window.Highcharts.chart('jobcontainer_' + category._id, {

• jquery.js = Pretty and easy to read :) Read this one.

• jquery.min.js = Looks like jibberish! But has a smaller file size. Put this one on your site.

Both are the same in functionality. The difference is only in whether it's formatted nicely for readability or compactly for smaller file size.

Specifically, the second one is minified, a process which involves removing unnecessary whitespace and shortening variable names. Both contribute to making the code much harder to read: the removal of whitespace removes line breaks and spaces messing up the formatting, and the shortening of variable names (including some function names) replaces the original variable names with meaningless letters.

All this is done in such a way that it doesn't affect the way the code behaves when run, in any way. Notably, the replacement/shortening of variable and function names is only done to names that appear in a local scope where it won't interfere with any other code in other scripts.

Kotlin short version:

import android.os.Build.MANUFACTURER
import android.os.Build.MODEL

fun getDeviceName(): String =
    (if (MODEL.startsWith(MANUFACTURER, ignoreCase = true)) {
        MODEL
    } else {
        "$MANUFACTURER $MODEL"
    }).capitalize()

You should be able to do that with the Batch Task plugin.

1. Create a batch task in the project.
2. Add a "Invoke batch tasks" post-build option selecting the same project.

An alternative can also be Post build task plugin.

Another workaround would be to spoof your IP using some sort of Public VPN or Tor network. This would be assuming the rate-limiting on the server at IP level.

There is a brief blog post demonstrating a way to use tor along with urllib2:

I've made my own head hurt over nothing! The Answer was very simple- I just went back to the basics...

some_Entities   e2 = new some_Entities(); //your entity.

add this line below after you update/delete - you're re-loading your entity-no fancy system methods.

e2 = new some_Entities(); //reset.

In order to close the port you could identify the process that is listening on this port and kill this process.

After installation you need to connect to Server Name : localhost to start using the local instance of SQL Server.

Once you are connected to the local instance, right click on Databases and create a new database.

On a Windows 64 bit machine, echo %programfiles(x86)% does print C:\Program Files (x86)

For a wrapper component, a simple solution would be to just use React.createElement directly (using ES6).

import RaisedButton from 'mui/RaisedButton'
import FlatButton from 'mui/FlatButton'
import IconButton from 'mui/IconButton'

class Button extends React.Component {
  render() {
    const { type, ...props } = this.props

    let button = null
    switch (type) {
      case 'flat': button = FlatButton
      break
      case 'icon': button = IconButton
      break
      default: button = RaisedButton
      break
    }

    return (
      React.createElement(button, { ...props, disableTouchRipple: true, disableFocusRipple: true })
    )
  }
}
