Programs & Examples On #Image load

I resolved the issue by double checking the "libs" directory and removing redundant jars, even though those jars were not manually added in the dependencies.

This could also be the case when you have too many object references. Take a look at the results from the build, esp in the task :dex:multiDebug:

trouble writing output: Too many method references: 67114; max is 65536.

for a button in a collapsed navbar nothing above worked for me so in my css file i did.....

.navbar button {
    margin:auto;
}

and it worked!!

To remove elements from an array, use the remove(at:), removeLast() and removeAll().

yourArray = [1,2,3,4]

Remove the value at 2 position

yourArray.remove(at: 2)

Remove the last value from array

yourArray.removeLast()

Removes all members from the set

yourArray.removeAll()

Use git rebase. Specifically:

1. Use git stash to store the changes you want to add.
2. Use git rebase -i HEAD~10 (or however many commits back you want to see).
3. Mark the commit in question (a0865...) for edit by changing the word pick at the start of the line into edit. Don't delete the other lines as that would delete the commits.[^vimnote]
4. Save the rebase file, and git will drop back to the shell and wait for you to fix that commit.
5. Pop the stash by using git stash pop
6. Add your file with git add <file>.
7. Amend the commit with git commit --amend --no-edit.
8. Do a git rebase --continue which will rewrite the rest of your commits against the new one.
9. Repeat from step 2 onwards if you have marked more than one commit for edit.

[^vimnote]: If you are using vim then you will have to hit the Insert key to edit, then Esc and type in :wq to save the file, quit the editor, and apply the changes. Alternatively, you can configure a user-friendly git commit editor with git config --global core.editor "nano".

I have used for getting route name in larvel 5.3

Request::path()

There should not be an Application.ShutDown(); or .Exit() message.

Application is a static class. It does not refer to the current application. You need to get to the current application and then shut it down like this:

Application.Current.Shutdown();

First cast your Edit text like this:

TextView tekst = (TextView) findViewById(R.id.editText1);
tekst.setText(text);

And after that close the DB not befor this line...

 myDataBaseHelper.close(); 

jQuery's .html() can be used for setting and getting the contents of matched non empty elements (innerHTML).

var contents = $(element).html();
$(element).html("insert content into element");

Initialize instance:

private String imagePath;
private List<String> imagePathList;

In onActivityResult You have to write this, If-else 2 block. One for single image and another for multiple image.

if (requestCode == GALLERY_CODE && resultCode == RESULT_OK  && data != null){

    imagePathList = new ArrayList<>();

    if(data.getClipData() != null){

        int count = data.getClipData().getItemCount();
        for (int i=0; i<count; i++){

            Uri imageUri = data.getClipData().getItemAt(i).getUri();
            getImageFilePath(imageUri);
        }
    }
    else if(data.getData() != null){

        Uri imgUri = data.getData();
        getImageFilePath(imgUri);
    }
}

Most important part, Get Image Path from uri:

public void getImageFilePath(Uri uri) {

    File file = new File(uri.getPath());
    String[] filePath = file.getPath().split(":");
    String image_id = filePath[filePath.length - 1];

    Cursor cursor = getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
    if (cursor!=null) {
        cursor.moveToFirst();
        imagePath = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
        imagePathList.add(imagePath);
        cursor.close();
    }
}

Hope this can help you.

To try to make this more clear:
for this github project: stant/mdcsvimporter2015
https://github.com/stant/mdcsvimporter2015
with releases at
https://github.com/stant/mdcsvimporter2015/releases

go to http or https: (note added "api." and "/repos")
https://api.github.com/repos/stant/mdcsvimporter2015/releases

you will get this json output and you can search for "download_count":

    "download_count": 2,
    "created_at": "2015-02-24T18:20:06Z",
    "updated_at": "2015-02-24T18:20:07Z",
    "browser_download_url": "https://github.com/stant/mdcsvimporter2015/releases/download/v18/mdcsvimporter-beta-18.zip"

or on command line do:
wget --no-check-certificate https://api.github.com/repos/stant/mdcsvimporter2015/releases

A hard reset will also resolve the problem

git reset --hard origin/master

There is also an 'E' status

E = File existed before update

This can happen if you have manually created a folder that would have been created by performing an update.

There is a version of string.Split that takes an array of strings and a StringSplitOptions parameter:

I think what you want is some form of the Ford–Fulkerson algorithm which is based on BFS. Its used to calculate the max flow of a network, by finding all augmenting paths between two nodes.

http://en.wikipedia.org/wiki/Ford%E2%80%93Fulkerson_algorithm

Siddharth's answer is nice, but relies on globally-scoped variables. There's a better, more OOP-friendly way.

A UserForm is a class module like any other - the only difference is that it has a hidden VB_PredeclaredId attribute set to True, which makes VB create a global-scope object variable named after the class - that's how you can write UserForm1.Show without creating a new instance of the class.

Step away from this, and treat your form as an object instead - expose Property Get members and abstract away the form's controls - the calling code doesn't care about controls anyway:

Option Explicit
Private cancelling As Boolean

Public Property Get UserId() As String
    UserId = txtUserId.Text
End Property

Public Property Get Password() As String
    Password = txtPassword.Text
End Property

Public Property Get IsCancelled() As Boolean
    IsCancelled = cancelling
End Property

Private Sub OkButton_Click()
    Me.Hide
End Sub

Private Sub CancelButton_Click()
    cancelling = True
    Me.Hide
End Sub

Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
    If CloseMode = VbQueryClose.vbFormControlMenu Then
        cancelling = True
        Cancel = True
        Me.Hide
    End If
End Sub

Now the calling code can do this (assuming the UserForm was named LoginPrompt):

With New LoginPrompt
    .Show vbModal
    If .IsCancelled Then Exit Sub
    DoSomething .UserId, .Password
End With

Where DoSomething would be some procedure that requires the two string parameters:

Private Sub DoSomething(ByVal uid As String, ByVal pwd As String)
    'work with the parameter values, regardless of where they came from
End Sub

You can use CAST and CONVERT to switch between different types of encodings. See: http://dev.mysql.com/doc/refman/5.0/en/charset-convert.html

SELECT column1, CONVERT(column2 USING utf8)
FROM my_table 
WHERE my_condition;

you can use:

intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

Works for positive or negative numbers

int start = -3;
int end = 6;

for (int val = start; val < end; val++)
{
    // Condition to Check Even, Not condition (!) will give Odd number
    if (val % 2 == 0) 
    {
        System.out.println("Even" + val);
    }
    else
    {
        System.out.println("Odd" + val);
    }
}

So there is another way you can actually fire it from any language. The best way I think, you can just create a batch file which will call your .dtsx package.

Next you call the batch file from any language. As in windows platform, you can run batch file from anywhere, I think this will be the most generic approach for your purpose. No code dependencies.

You can use this in Kotlin extentions.kt

fun Context.isPackageInstalled(packageName: String): Boolean {
    return try {
        packageManager.getPackageInfo(packageName, 0)
        true
    } catch (e: PackageManager.NameNotFoundException) {
        false
    }
}

Usage

context.isPackageInstalled("com.somepackage.name")

Your Customer class has to be discovered by CDI as a bean. For that you have two options:

1. Put a bean defining annotation on it. As @Model is a stereotype it's why it does the trick. A qualifier like @Named is not a bean defining annotation, reason why it doesn't work

2. Change the bean discovery mode in your bean archive from the default "annotated" to "all" by adding a beans.xml file in your jar.

Keep in mind that @Named has only one usage : expose your bean to the UI. Other usages are for bad practice or compatibility with legacy framework.

It depends on what the zip contains. Take a look to see if it got content.jar and artifacts.jar. If it does, it is an archived updated site. Install from it the same way as you install from a remote site.

If the zip doesn't contain content.jar and artifacts.jar, go to your Eclipse install's dropins directory, create a subfolder (name doesn't matter) and expand your zip into that folder. Restart Eclipse.

If you are using this for Angular, then export a function via a named export. Such as:

function someFunc(){}

export { someFunc as someFuncName }

otherwise, Angular will complain that object is not a function.

You cannot.

According to the XML Schema specification, a boolean is true or false. True is not valid:

  3.2.2.1 Lexical representation
  An instance of a datatype that is defined as ·boolean· can have the 
  following legal literals {true, false, 1, 0}. 

  3.2.2.2 Canonical representation
  The canonical representation for boolean is the set of 
  literals {true, false}. 

If the tool you are using truly validates against the XML Schema standard, then you cannot convince it to accept True for a boolean.

It will give you all active sockets on a specific IP:

netstat -an | find "172.20.1.166"

Chrome headless now supports an extra options --print-to-pdf-no-header which removed header and footer from the printed PDF file

In my case the above suggestions did not work for me. Mine was little different scenario.

When i tried installing bundler using gem install bundler .. But i was getting

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

then i tried using sudo gem install bundler then i was getting

ERROR:  While executing gem ... (Gem::FilePermissionError)
  You don't have write permissions for the /usr/bin directory.

then i tried with sudo gem install bundler -n /usr/local/bin ( Just /usr/bin dint work in my case ).

And then successfully installed bundler

EDIT: I use MacOS, maybe /usr/bin din't work for me for that reason (https://stackoverflow.com/a/34989655/3786657 comment )

I suggest forget the pre and just put it in a textarea.

Your indenting will remain and your code wont get word-wrapped in the middle of a path or something.

Easier to select text range in a text area too if you want to copy to clipboard.

The following is a php excerpt so if your not in php then the way you pack the html special chars will vary.

<textarea style="font-family:monospace;" onfocus="copyClipboard(this);"><?=htmlspecialchars($codeBlock);?></textarea>

For info on how to copy text to the clipboard in js see: How do I copy to the clipboard in JavaScript? .

However...

I just inspected the stackoverflow code blocks and they wrap in a <code> tag wrapped in <pre> tag with css ...

code {
  background-color: #EEEEEE;
  font-family: Consolas,Menlo,Monaco,Lucida Console,Liberation Mono,DejaVu Sans Mono,Bitstream Vera Sans Mono,Courier New,monospace,serif;
}
pre {
  background-color: #EEEEEE;
  font-family: Consolas,Menlo,Monaco,Lucida Console,Liberation Mono,DejaVu Sans Mono,Bitstream Vera Sans Mono,Courier New,monospace,serif;
  margin-bottom: 10px;
  max-height: 600px;
  overflow: auto;
  padding: 5px;
  width: auto;
}

Also the content of the stackoverflow code blocks is syntax highlighted using (I think) http://code.google.com/p/google-code-prettify/ .

Its a nice setup but Im just going with textareas for now.

When you're using GROUP BY, you need to also use aggregate functions for the columns not inside your group by clause.

I don't know exactly what you're trying to do, but I guess this would work:

select 
    LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000),
    PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
    qvalues.name,
    qvalues.compound,
    MAX(qvalues.rid)
from
    batchinfo join qvalues on batchinfo.rowid=qvalues.rowid
where
    LEN(datapath)>4
group by
    LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000),
    PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
    qvalues.name,
    qvalues.compound
having
    rid!=MAX(rid)

Edit: What I'm trying to do here is a group by with all fields but rid. If that's not what you want, what you need to do in order to have a valid SQL statement is adding an aggregate function call for each removed group by field...

Since for me, some elements are created on page load, and some are dynamically added by the user; I used this to make sure everything stayed DRY.

On submit, find everything with class x, remove class x, add rule x.

$('#form').on('submit', function(e) {
    $('.alphanumeric_dash').each(function() {
        var $this = $(this);
        $this.removeClass('alphanumeric_dash');
        $(this).rules('add', {
            alphanumeric_dash: true
        });
    });
});

The DateTime class takes a string in the constructor. If you prefix the timestamp with a @-character you create a DateTime object with the timestamp. For formating use the 'c' format ... a predefined ISO 8601 compound format.

If could use the DateTime class like this ... set the right timezone or leave it out if you want a UTC time.

$dt = new DateTime('@1333699439');
$dt->setTimezone(new DateTimeZone('America/New_York'));
echo $dt->format('c');

How to check if a file exists in Ansible using when condition

**

Below is the ansible play i used to remove the file when the file exists in the OS end.

 - name: find out /etc/init.d/splunk file exists or not'
      stat:
        path: /etc/init.d/splunk
      register: splunkresult
      tags:
        - always

    - name: 'Remove splunk from init.d file if splunk already running'
      file:
        path: /etc/init.d/splunk
        state: absent
      when: splunkresult.stat.exists == true
      ignore_errors: yes
      tags:
        - always

I have used play condition as like below

when: splunkresult.stat.exists == true --> Remove the file

you can give true/false based on your requirement

when: splunkresult.stat.exists == false
when: splunkresult.stat.exists == true

Python 2 will automatically set the type based on the size of the value. A guide of max values can be found below.

The Max value of the default Int in Python 2 is 65535, anything above that will be a long

For example:

>> print type(65535)
<type 'int'>
>>> print type(65536*65536)
<type 'long'>

In Python 3 the long datatype has been removed and all integer values are handled by the Int class. The default size of Int will depend on your CPU architecture.

For example:

• 32 bit systems the default datatype for integers will be 'Int32'
• 64 bit systems the default datatype for integers will be 'Int64'

The min/max values of each type can be found below:

• Int8: [-128,127]
• Int16: [-32768,32767]
• Int32: [-2147483648,2147483647]
• Int64: [-9223372036854775808,9223372036854775807]
• Int128: [-170141183460469231731687303715884105728,170141183460469231731687303715884105727]
• UInt8: [0,255]
• UInt16: [0,65535]
• UInt32: [0,4294967295]
• UInt64: [0,18446744073709551615]
• UInt128: [0,340282366920938463463374607431768211455]

If the size of your Int exceeds the limits mentioned above, python will automatically change it's type and allocate more memory to handle this increase in min/max values. Where in Python 2, it would convert into 'long', it now just converts into the next size of Int.

Example: If you are using a 32 bit operating system, your max value of an Int will be 2147483647 by default. If a value of 2147483648 or more is assigned, the type will be changed to Int64.

There are different ways to check the size of the int and it's memory allocation. Note: In Python 3, using the built-in type() method will always return <class 'int'> no matter what size Int you are using.

You can use above function for casting not similar class objects (PHP >= 5.3)

/**
 * Class casting
 *
 * @param string|object $destination
 * @param object $sourceObject
 * @return object
 */
function cast($destination, $sourceObject)
{
    if (is_string($destination)) {
        $destination = new $destination();
    }
    $sourceReflection = new ReflectionObject($sourceObject);
    $destinationReflection = new ReflectionObject($destination);
    $sourceProperties = $sourceReflection->getProperties();
    foreach ($sourceProperties as $sourceProperty) {
        $sourceProperty->setAccessible(true);
        $name = $sourceProperty->getName();
        $value = $sourceProperty->getValue($sourceObject);
        if ($destinationReflection->hasProperty($name)) {
            $propDest = $destinationReflection->getProperty($name);
            $propDest->setAccessible(true);
            $propDest->setValue($destination,$value);
        } else {
            $destination->$name = $value;
        }
    }
    return $destination;
}

EXAMPLE:

class A 
{
  private $_x;   
}

class B 
{
  public $_x;   
}

$a = new A();
$b = new B();

$x = cast('A',$b);
$x = cast('B',$a);

For relative imports you have to:

• a) use relative name

• b) provide anchor explicitly

  importlib.import_module('.c', 'a.b')
  

Of course, you could also just do absolute import instead:

importlib.import_module('a.b.c')

I collected many topics to make universal function with many outputs (years, months, days, hours, minutes, seconds) with string or parse to int and direction +- if you need to know what side is direction of the difference.

Use example:

    $date1='2016-05-27 02:00:00';
    $format='Y-m-d H:i:s';

    echo timeDifference($date1, $format, '2017-08-30 00:01:59', $format); 
    #1 years 3 months 2 days 22 hours 1 minutes 59 seconds (string)

    echo timeDifference($date1, $format, '2017-08-30 00:01:59', $format,false, '%a days %h hours');
    #459 days 22 hours (string)

    echo timeDifference('2016-05-27 00:00:00', $format, '2017-08-30 00:01:59', $format,true, '%d days -> %H:%I:%S', true);
    #-3 days -> 00:01:59 (string)

    echo timeDifference($date1, $format, '2016-05-27 00:05:51', $format, false, 'seconds');
    #9 (string)

    echo timeDifference($date1, $format, '2016-05-27 07:00:00', $format, false, 'hours');
    #5 (string)

    echo timeDifference($date1, $format, '2016-05-27 07:00:00', $format, true, 'hours');
    #-5 (string)

    echo timeDifference($date1, $format, '2016-05-27 07:00:00', $format, true, 'hours',true);
    #-5 (int)

Function

    function timeDifference($date1_pm_checked, $date1_format,$date2, $date2_format, $plus_minus=false, $return='all', $parseInt=false)
    {
        $strtotime1=strtotime($date1_pm_checked);
        $strtotime2=strtotime($date2);
        $date1 = new DateTime(date($date1_format, $strtotime1));
        $date2 = new DateTime(date($date2_format, $strtotime2));
        $interval=$date1->diff($date2);

        $plus_minus=(empty($plus_minus)) ? '' : ( ($strtotime1 > $strtotime2) ? '+' : '-'); # +/-/no_sign before value 

        switch($return)
        {
            case 'y';
            case 'year';
            case 'years';
                $elapsed = $interval->format($plus_minus.'%y');
                break;

            case 'm';
            case 'month';
            case 'months';
                $elapsed = $interval->format($plus_minus.'%m');
                break;

            case 'a';
            case 'day';
            case 'days';
                $elapsed = $interval->format($plus_minus.'%a');
                break;

            case 'd';
                $elapsed = $interval->format($plus_minus.'%d');
                break;

            case 'h';       
            case 'hour';        
            case 'hours';       
                $elapsed = $interval->format($plus_minus.'%h');
                break;

            case 'i';
            case 'minute';
            case 'minutes';
                $elapsed = $interval->format($plus_minus.'%i');
                break;

            case 's';
            case 'second';
            case 'seconds';
                $elapsed = $interval->format($plus_minus.'%s');
                break;

            case 'all':
                $parseInt=false;
                $elapsed = $plus_minus.$interval->format('%y years %m months %d days %h hours %i minutes %s seconds');
                break;

            default:
                $parseInt=false;
                $elapsed = $plus_minus.$interval->format($return);
        }

        if($parseInt)
            return (int) $elapsed;
        else
            return $elapsed;

    }

You can pass arbitrary parameters through the query string, but you can also set up custom routes to handle it in a RESTful way:

http://ws.audioscrobbler.com/2.0/?method=artist.getimages&artist=cher&
                                  api_key=b25b959554ed76058ac220b7b2e0a026

That could be:

routes.MapRoute(
    "ArtistsImages",
    "{ws}/artists/{artist}/{action}/{*apikey}",
    new { ws = "2.0", controller="artists" artist = "", action="", apikey="" }
    );

So if someone used the following route:

ws.audioscrobbler.com/2.0/artists/cher/images/b25b959554ed76058ac220b7b2e0a026/

It would take them to the same place your example querystring did.

The above is just an example, and doesn't apply the business rules and constraints you'd have to set up to make sure people didn't 'hack' the URL.

Below command works , i tried this and got the current version as

/usr/bin/hive --version

You can drop the new string[] part:

List<string> values = new List<string> { "one", "two", "three" };

There is a function in c called isdigit(). That will suit you just fine. Example:

int var1 = 'h';
int var2 = '2';

if( isdigit(var1) )
{
   printf("var1 = |%c| is a digit\n", var1 );
}
else
{
   printf("var1 = |%c| is not a digit\n", var1 );
}
if( isdigit(var2) )
{
  printf("var2 = |%c| is a digit\n", var2 );
}
else
{
   printf("var2 = |%c| is not a digit\n", var2 );
}

From here

You could use git reset (see docs)

Below command will display the modfied files alone in windows.

[headingButton setTitleColor:[UIColor colorWithRed:36/255.0 green:71/255.0 blue:113/255.0 alpha:1.0] forState:UIControlStateNormal];

Swift

headingButton.setTitleColor(.black, for: .normal)

If you are using Rating bar in Linearlayout with weightSum. Please make sure that you should not assign the layout_weight for rating bar. Instead, that place rating bar inside relative layout and give weight to the relative layout. Make rating bar width wrap content.

<RelativeLayout
    android:layout_width="0dp"
    android:layout_weight="30"
    android:layout_gravity="center"
    android:layout_height="wrap_content">
        <RatingBar
            android:id="@+id/userRating"
            style="@style/Widget.AppCompat.RatingBar.Small"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:stepSize="1" />
</RelativeLayout>

ES6 one liner

const toTitleCase = string => string.split(' ').map((word) => [word[0].toUpperCase(), ...word.substr(1)].join('')).join(' ');

jQuery's attr method returns the value of the attribute:

The .attr() method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's .each() or .map() method.

All you need is:

$('html').attr('lang') == 'fr-FR'

However, you might want to do a case-insensitive match:

$('html').attr('lang').toLowerCase() === 'fr-fr'

jQuery's val method returns the value of a form element.

The .val() method is primarily used to get the values of form elements such as input, select and textarea. In the case of <select multiple="multiple"> elements, the .val() method returns an array containing each selected option; if no option is selected, it returns null.

Go to the folder where Python is installed, e.g., in my case (Mac OS) it is installed in the Applications folder with the folder name 'Python 3.6'. Now double click on 'Install Certificates.command'. You will no longer face this error.

For those not running a mac, or having a different setup and can't find this file, the file merely runs:

pip install --upgrade certifi

Hope that helps someone :)

I was having a similar issue when I wanted to modify the array state while retaining the position of the element in the array

This is a function to toggle between like and unlike:

    const liker = (index) =>
        setData((prevState) => {
            prevState[index].like = !prevState[index].like;
            return [...prevState];
        });

as we can say the function takes the index of the element in the array state, and we go ahead and modify the old state and rebuild the state tree

If the key you are looking for isn't present in the config file, you won't be able to convert it to a string with .ToString() because the value will be null and you'll get an "Object reference not set to an instance of an object" error. It's best to first see if the value exists before trying to get the string representation.

if (!String.IsNullOrEmpty(ConfigurationManager.AppSettings["myKey"]))
{
    String myKey = ConfigurationManager.AppSettings["myKey"].ToString();
}

Or, as Code Monkey suggested:

if (ConfigurationSettings.AppSettings["myKey"] != null)
{
// Now do your magic..
}

This can now be done as of docker-compose v2+ as part of the build object;

docker-compose.yml

version: '2'
services:
    my_image_name:
        build:
            context: . #current dir as build context
            args:
                var1: 1
                var2: c

See the docker compose docs.

In the above example "var1" and "var2" will be sent to the build environment.

Note: any env variables (specified by using the environment block) which have the same name as args variable(s) will override that variable.

If you do something like this:

    cmd.Parameters.Add("@blah",SqlDbType.VarChar).Value = "some large text";

size will be taken from "some large text".Length

This can be problematic when it's an output parameter, you get back no more characters then you put as input.

the file is a native DLL which means you can't add it to a .NET project via Add Reference... you can use it via DllImport (see http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.dllimportattribute.aspx)

You must use Rect.width() and Rect.Height() which returned from getTextBounds() instead. That works for me.

typeof(IMyInterface).IsAssignableFrom(someclass.GetType());

or

typeof(IMyInterface).IsAssignableFrom(typeof(MyType));

A) For a cheap comparison / arithmetics dummy use math.inf. Or math.nan, which compares FALSE in any direction (including nan == nan) except identity check (is) and renders any arithmetics (like nan - nan) nan. Or a reasonably high real integer number according to your use case (e.g. sys.maxsize). For a bitmask dummy (e.g. in mybits & bitmask) use -1.

B) To get the platform primitive maximum signed long int (or long long):

>>> 256 ** sys.int_info.sizeof_digit // 2 - 1  # Python’s internal primitive
2147483647
>>> 256 ** ctypes.sizeof(ctypes.c_long) // 2 - 1  # CPython
2147483647
>>> 256 ** ctypes.sizeof(ctypes.c_longlong) // 2 - 1  # CPython
9223372036854775807
>>> 2**63 - 1  # Java / JPython primitive long
9223372036854775807

C) The maximum Python integer could be estimated by a long running loop teasing for a memory overflow (try 256**int(8e9) - can be stopped by KeyboardInterrupt). But it cannot not be used reasonably, because its representation already consumes all the memory and its much greater than sys.float_info.max.

You can set any pointer to NULL, though NULL is simply defined as 0 in C++:

myObject *foo = NULL;

Also note that NULL is defined if you include standard headers, but is not built into the language itself. If NULL is undefined, you can use 0 instead, or include this:

#ifndef NULL
#define NULL 0
#endif

As an aside, if you really want to set an object, not a pointer, to NULL, you can read about the Null Object Pattern.

matches() is an XPATH 2.0 function that allows for case-insensitive regex matching.

One of the flags is i for case-insensitive matching.

The following XPATH using the matches() function with the case-insensitive flag:

//CD[matches(@title,'empire burlesque','i')]

List<SubProduct> subProducts= (List<SubProduct>)Model.subproduct;

The implicit conversion failes because List<> implements IList, not viceversa. So you can say IList<T> foo = new List<T>(), but not List<T> foo = (some IList-returning method or property).

string remove = Regex.Replace(txtsp.Value).ToUpper(), @"\t|\n|\r", "");

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 }})

The subset command is not necessary. Just use data frame indexing

studentdata[studentdata$Drink == 'water',]

Read the warning from ?subset

This is a convenience function intended for use interactively. For programming it is better to use the standard subsetting functions like ‘[’, and in particular the non-standard evaluation of argument ‘subset’ can have unanticipated consequences.

I'm running python 3.5 and subprocess.call(['./test.sh']) doesn't work for me.

I give you three solutions depends on what you wanna do with the output.

1 - call script. You will see output in your terminal. output is a number.

import subprocess 
output = subprocess.call(['test.sh'])

2 - call and dump execution and error into string. You don't see execution in your terminal unless you print(stdout). Shell=True as argument in Popen doesn't work for me.

import subprocess
from subprocess import Popen, PIPE

session = subprocess.Popen(['test.sh'], stdout=PIPE, stderr=PIPE)
stdout, stderr = session.communicate()

if stderr:
    raise Exception("Error "+str(stderr))

3 - call script and dump the echo commands of temp.txt in temp_file

import subprocess
temp_file = open("temp.txt",'w')
subprocess.call([executable], stdout=temp_file)
with open("temp.txt",'r') as file:
    output = file.read()
print(output)

Don't forget to take a look at the doc subprocess

Consider using subtree instead of submodules, it will make your repo users life much easier. You may find more detailed guide in Pro Git book.

Use zip(*list):

>>> l = [(1,2), (3,4), (8,9)]
>>> list(zip(*l))
[(1, 3, 8), (2, 4, 9)]

The zip() function pairs up the elements from all inputs, starting with the first values, then the second, etc. By using *l you apply all tuples in l as separate arguments to the zip() function, so zip() pairs up 1 with 3 with 8 first, then 2 with 4 and 9. Those happen to correspond nicely with the columns, or the transposition of l.

zip() produces tuples; if you must have mutable list objects, just map() the tuples to lists or use a list comprehension to produce a list of lists:

map(list, zip(*l))          # keep it a generator
[list(t) for t in zip(*l)]  # consume the zip generator into a list of lists

If RecyclerView showing only one row inside ScrollView. You just need to set height of your row to android:layout_height="wrap_content".

Simple ready2use snippet, working perfectly for me

static void waitForPageLoad(WebDriver wdriver) {
    WebDriverWait wait = new WebDriverWait(wdriver, 60);

    Predicate<WebDriver> pageLoaded = new Predicate<WebDriver>() {

        @Override
        public boolean apply(WebDriver input) {
            return ((JavascriptExecutor) input).executeScript("return document.readyState").equals("complete");
        }

    };
    wait.until(pageLoaded);
}

I also think it is important to note that Python dict object type is a hash table (more on this here), and thus is not capable of being sorted without converting its keys/values to lists. What this allows is dict item retrieval in constant time O(1), no matter the size/number of elements in a dictionary.

Having said that, once you sort its keys - sorted(data.keys()), or values - sorted(data.values()), you can then use that list to access keys/values in design patterns such as these:

for sortedKey in sorted(dictionary):
    print dictionary[sortedKeY] # gives the values sorted by key

for sortedValue in sorted(dictionary.values()):
    print sortedValue # gives the values sorted by value

Hope this helps.

Using DataTable is valid as user927524 stated. You can also do it by adding rows manually, which will not require to add a specific wrapping class:

List<string> filenamesList = ...;
foreach(string filename in filenamesList)
      gvFilesOnServer.Rows.Add(new object[]{filename});

In any case, thanks user927524 for clearing this weird behavior!!

Yes, the error you are getting means that there is not a private key on your Mac associated with the distribution certificate you are trying to use to sign the app.

There are two possible solutions, depending on whether the computer who requested the distribution certificate is available or not.

If the computer who requested the distribution certificate is available (or there is a backup of the distribution assets somewhere)

1. From the computer where the distribution asset was generated, open Xcode.
2. Click on Window, Organizer.
3. Expand the Teams section.
4. Select your team, select the certificate of "iOS Distribution" type, click Export and follow the instructions.
5. Save the exported file and go to your computer.
6. Repeat steps 1-3.
7. Click Import and select the file you exported before.

If the computer where the distribution profile was created is not accessible anymore (and there is not a backup)

You have to revoke the certificate and create a new one.

You may need to ask your team admin or agent to give you some privileges in order to generate distribution certificates. Once you have enough privileges, follow these steps (accurate as of 15-May-2013):

1. Go to this webpage: https://developer.apple.com/devcenter/ios/index.action
2. Click on "Member Center" and enter your iOS developer credentials.
3. Click on "Certificates, Identifiers & Profiles".
4. Click on "Certificates" under the "iOS Apps" section.
5. Expand the Certificates section on the left, select Distribution, and click on your distribution certificate.
6. Click Revoke and follow the instructions.
7. Click on the plus sign to add a new certificate.
8. Select "App Store and Ad Hoc" option, and click Continue.
9. Follow the steps printed in the webpage. That involves opening the Keychain application on your Mac and generate a Certificate Signing Request from there. Click Continue.
10. Upload the .csr file and click Continue.
11. A certificate is generated for distribution. Download it and double click it to integrate it in your keychain.

Reopen Xcode and check your project configuration to see if you can now select an "iPhone Distribution" certificate (i.e. it's not grayed out).

It's been a while since I used it, but JavaLayer is great for MP3 playback

I found this one quite useful. here's the source

In Windows Forms, if your string is in a textbox, you can easily use this:

textBoxcsharp.SelectAll();
textBoxcsharp.Copy();
textBoxcsharp.DeselectAll();

seems you can't find the full path in you localhost by js, but you can hide the fakepath to just show the file name. Use jQuery to get the file input's selected filename without the path

In NoSQL: If Only It Was That Easy, the author writes about MongoDB:

MongoDB is not a key/value store, it’s quite a bit more. It’s definitely not a RDBMS either. I haven’t used MongoDB in production, but I have used it a little building a test app and it is a very cool piece of kit. It seems to be very performant and either has, or will have soon, fault tolerance and auto-sharding (aka it will scale). I think Mongo might be the closest thing to a RDBMS replacement that I’ve seen so far. It won’t work for all data sets and access patterns, but it’s built for your typical CRUD stuff. Storing what is essentially a huge hash, and being able to select on any of those keys, is what most people use a relational database for. If your DB is 3NF and you don’t do any joins (you’re just selecting a bunch of tables and putting all the objects together, AKA what most people do in a web app), MongoDB would probably kick ass for you.

Then, in the conclusion:

The real thing to point out is that if you are being held back from making something super awesome because you can’t choose a database, you are doing it wrong. If you know mysql, just use it. Optimize when you actually need to. Use it like a k/v store, use it like a rdbms, but for god sake, build your killer app! None of this will matter to most apps. Facebook still uses MySQL, a lot. Wikipedia uses MySQL, a lot. FriendFeed uses MySQL, a lot. NoSQL is a great tool, but it’s certainly not going to be your competitive edge, it’s not going to make your app hot, and most of all, your users won’t care about any of this.

What am I going to build my next app on? Probably Postgres. Will I use NoSQL? Maybe. I might also use Hadoop and Hive. I might keep everything in flat files. Maybe I’ll start hacking on Maglev. I’ll use whatever is best for the job. If I need reporting, I won’t be using any NoSQL. If I need caching, I’ll probably use Tokyo Tyrant. If I need ACIDity, I won’t use NoSQL. If I need a ton of counters, I’ll use Redis. If I need transactions, I’ll use Postgres. If I have a ton of a single type of documents, I’ll probably use Mongo. If I need to write 1 billion objects a day, I’d probably use Voldemort. If I need full text search, I’d probably use Solr. If I need full text search of volatile data, I’d probably use Sphinx.

I like this article, I find it very informative, it gives a good overview of the NoSQL landscape and hype. But, and that's the most important part, it really helps to ask yourself the right questions when it comes to choose between RDBMS and NoSQL. Worth the read IMHO.

I'll go ahead and throw this answer in because it is all I needed when I had the same question:

Date currentDate = new Date(System.currentTimeMillis());

currentDate is now your current date in a Java Date object.

For those looking on how to do it when you have an array of elements:

const textInputRefs = useRef<(HTMLDivElement | null)[]>([])

...

const onClickFocus = (event: React.BaseSyntheticEvent, index: number) => {
    textInputRefs.current[index]?.focus()
};

...

{items.map((item, index) => (
    <textInput
        inputRef={(ref) => textInputs.current[index] = ref}
    />
    <Button
        onClick={event => onClickFocus(event, index)}
    />
}

Anaconda comes with the conda package manager which is designed to handle these kinds of upgrades. Start by updating conda itself to get the most recent package lists:

conda update conda

And then install the version of scikit-learn you want

conda install scikit-learn=0.17

All necessary dependencies will be upgraded as well. If you have trouble with conda on Windows, there are some relevant FAQ here: http://docs.continuum.io/anaconda/faq

The easiest way: Use gson, google's own goto json library. https://code.google.com/p/google-gson/

Here is a sample. I'm going to this free geolocator website and parsing the json and displaying my zipcode. (just put this stuff in a main method to test it out)

    String sURL = "http://freegeoip.net/json/"; //just a string

    // Connect to the URL using java's native library
    URL url = new URL(sURL);
    URLConnection request = url.openConnection();
    request.connect();

    // Convert to a JSON object to print data
    JsonParser jp = new JsonParser(); //from gson
    JsonElement root = jp.parse(new InputStreamReader((InputStream) request.getContent())); //Convert the input stream to a json element
    JsonObject rootobj = root.getAsJsonObject(); //May be an array, may be an object. 
    String zipcode = rootobj.get("zip_code").getAsString(); //just grab the zipcode

A workaround can be to create a file (i.e list.txt) with nothing inside, in this file you can set the custom metadata (that is a Map< String, String>) with the list of all the file's URL.
So if you need to downlaod all the files in a fodler you first download the metadata of the list.txt file, then you iterate through the custom data and download all the files with the URLs in the Map.

In case you don't want to mess with the ~/.ssh/config file mentioned here, you could instead run git config core.sshCommand "ssh -i ~/.ssh/custom_id_rsa" in the repo where you want to commit from a different account.

The rest of the setup is the same:

1. Create a new SSH key for the second account with ssh-keygen -t rsa -f ~/.ssh -f ~/.ssh/custom_id_rsa

2. Sign in to github with your other account, go to https://github.com/settings/keys , and paste the contents of ~/.ssh/custom_id_rsa.pub

3. Make sure you're using SSH instead of HTTPS as remote url: git remote set-url origin [email protected]:upstream_project_teamname/upstream_project.git

Be sure that android:debuggable="true" is set in the application tag of your manifest file, and then:

1. Plug your phone into your computer and enable USB debugging on the phone
2. Open eclipse and a workspace containing the code for your app
3. In Eclipse, go to Window->Show View->Devices
4. Look at the Devices view which should now be visible, you should see your device listed
5. If your device isn't listed, you'll have to track down the ADB drivers for your phone before continuing
6. If you want to step through code, set a breakpoint somewhere in your app
7. Open the app on your phone
8. In the Devices view, expand the entry for your phone if it isn't already expanded, and look for your app's package name.
9. Click on the package name, and in the top right of the Devices view you should see a green bug along with a number of other small buttons. Click the green bug.
10. You should now be attached/debugging your app.

In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.

In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.

The /me/friendlists endpoint and user_friendlists permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.

If you want to access a list of non-app-using friends, there are two options:

1. If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.

2. If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.

In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission).

For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.

The following technique worked for me:

1) Right click on the project Solution -> Click on Clean solution

2) Right click on the project Solution -> Click on Rebuild solution

• .exe - the 'normal' executable

• .vshost.exe - a special version of the executable to aid debuging; see MSDN for details

• .pdb - the Program Data Base with debug symbols

• .vshost.exe.manifest - a kind of configuration file containing mostly dependencies on libraries

Yes this topic is a bit old but i wanted to share the solution that worked for me for those who might need it anyway

As Ali said, try to locate your program using the following from terminal :

 sudo python3
 import serial

print(serial.__file__) --> Copy

CTRL+D #(to get out of python)

sudo python3-->paste/__init__.py

Activating __init__.py will say to your program "ok i'm going to use Serial from python3". My problem was that my python3 program was using Serial from python 2.7

Try using the following code.

$(document).ready(function(){
    $("a[@href^='http']").attr('target','_blank');
});

If you can get access from a Windows machine, you can use xcopy with /T and /E to copy just the folder structure (the /E includes empty folders)

[EDIT!]

This one uses rsync to recreate the directory structure but without the files. http://psung.blogspot.com/2008/05/copying-directory-trees-with-rsync.html

Might actually be better :)

You can use the Number.isFinite() function:

Number.isFinite(Infinity);  // false
Number.isFinite(NaN);       // false
Number.isFinite(-Infinity); // false
Number.isFinite('0');       // false
Number.isFinite(null);      // false

Number.isFinite(0);         // true
Number.isFinite(2e64);      // true

Note: there's a significant difference between the global function isFinite() and the latter Number.isFinite(). In the case of the former, string coercion is performed - so isFinite('0') === true whilst Number.isFinite('0') === false.

Also, note that this is not available in IE!

How about a one liner?

$('input:radio[name="gender"]').filter('[value="Male"]').attr('checked', true);

box-shadow: -15px 0px 17px -7px rgba(0,0,0,0.75);

The first px value is the "Horizontal Length" set to -15px to position the shadow towards the left, the next px value is set to 0 so the shadow top and bottom is centred to minimise the top and bottom shadow.

The third value(17px) is known as the blur radius. The higher the number, the more blurred the shadow will be. And then last px value -7px is The spread radius, a positive value increases the size of the shadow, a negative value decreases the size of the shadow, at -7px it keeps the shadow from appearing above and below the item.

Right click on JSON file, select open, navigate to program you want open with(notepad). Consecutive opens automatically use notepad.

Here you have used native and assigning value to the primary key, in native primary key is auto generated.

Hence the issue is coming.

The second way is a tad more efficient, but a much better way is to execute them in batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
        }

        statement.executeBatch();
    }
}

You're however dependent on the JDBC driver implementation how many batches you could execute at once. You may for example want to execute them every 1000 batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        int i = 0;

        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
            i++;

            if (i % 1000 == 0 || i == entities.size()) {
                statement.executeBatch(); // Execute every 1000 items.
            }
        }
    }
}

As to the multithreaded environments, you don't need to worry about this if you acquire and close the connection and the statement in the shortest possible scope inside the same method block according the normal JDBC idiom using try-with-resources statement as shown in above snippets.

If those batches are transactional, then you'd like to turn off autocommit of the connection and only commit the transaction when all batches are finished. Otherwise it may result in a dirty database when the first bunch of batches succeeded and the later not.

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (Connection connection = dataSource.getConnection()) {
        connection.setAutoCommit(false);

        try (PreparedStatement statement = connection.prepareStatement(SQL)) {
            // ...

            try {
                connection.commit();
            } catch (SQLException e) {
                connection.rollback();
                throw e;
            }
        }
    }
}

Just another clean way:

  function validateIp($var_ip){
    $ip = trim($var_ip);

    return (!empty($ip) &&
            $ip != '::1' &&
            $ip != '127.0.0.1' &&
            filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false)
            ? $ip : false;
  }

  function getClientIp() {
    $ip = @$this->validateIp($_SERVER['HTTP_CLIENT_IP']) ?:
          @$this->validateIp($_SERVER['HTTP_X_FORWARDED_FOR']) ?:
          @$this->validateIp($_SERVER['HTTP_X_FORWARDED']) ?:
          @$this->validateIp($_SERVER['HTTP_FORWARDED_FOR']) ?:
          @$this->validateIp($_SERVER['HTTP_FORWARDED']) ?:
          @$this->validateIp($_SERVER['REMOTE_ADDR']) ?:
          'LOCAL OR UNKNOWN ACCESS';

    return $ip;
  }

declare @MyNumber float 
set @MyNumber = 123.45 
select 'My number is ' + CAST(@MyNumber as nvarchar(max))

This issue can also be caused if you include the normal jquery library twice. I had the following line twice, in my body and head.

It never caused any problems until I tried to use jquery UI as well.

You might find the Semantic Versioning Specification useful.

If you are reading from a file then you should hear the advice given and just put it into a double.

On the other hand, if you do have, say, a string you could use boost's lexical_cast.

Here is a (very simple) example:

int Foo(std::string anInt)
{
   return lexical_cast<int>(anInt);
}

SQLite 3

Using getMetaData();

DatabaseMetaData md = conn.getMetaData();
ResultSet rset = md.getColumns(null, null, "your_table_name", null);

System.out.println("your_table_name");
while (rset.next())
{
    System.out.println("\t" + rset.getString(4));
}

EDIT: This works with PostgreSQL as well

Use hsh.delete_if. In your specific case, something like: hsh.delete_if { |k, v| v.empty? }

public static bool CompareDateTimes(this DateTime firstDate, DateTime secondDate) 
{
   return firstDate.Day == secondDate.Day && firstDate.Month == secondDate.Month && firstDate.Year == secondDate.Year;
}

Try this one http://jsfiddle.net/Husamuddin/ByNa3/ it works fine with me,
css

.table {
    width:100%;
    height:100%;
    position:absolute;
    display:table;
}
.cell {
    display:table-cell;
    vertical-align:middle;
    width:100%;
    height:100%:
}

and the html

<div class="table">
    <div class="cell">Hello, I'm in the middle</div>
</div>

var list = db.Discounts.ToList().Select(x => x as Discount);
foreach (var item in list)
{
    db.Discounts.Remove(item);
}
db.SaveChanges();

Document has already explain the usage. So I am using SQL to explain these methods

Example:

Assuming there is an Order (orders) has many OrderItem (order_items).

And you have already build the relationship between them.

// App\Models\Order:
public function orderItems() {
    return $this->hasMany('App\Models\OrderItem', 'order_id', 'id');
}

These three methods are all based on a relationship.

With

Result: with() return the model object and its related results.

Advantage: It is eager-loading which can prevent the N+1 problem.

When you are using the following Eloquent Builder:

Order::with('orderItems')->get();

Laravel change this code to only two SQL:

// get all orders:
SELECT * FROM orders; 

// get the order_items based on the orders' id above
SELECT * FROM order_items WHERE order_items.order_id IN (1,2,3,4...);

And then laravel merge the results of the second SQL as different from the results of the first SQL by foreign key. At last return the collection results.

So if you selected columns without the foreign_key in closure, the relationship result will be empty:

Order::with(['orderItems' => function($query) { 
           // $query->sum('quantity');
           $query->select('quantity'); // without `order_id`
       }
])->get();

#=> result:
[{  id: 1,
    code: '00001',
    orderItems: [],    // <== is empty
  },{
    id: 2,
    code: '00002',
    orderItems: [],    // <== is empty
  }...
}]

Has

Has will return the model's object that its relationship is not empty.

Order::has('orderItems')->get();

Laravel change this code to one SQL:

select * from `orders` where exists (
    select * from `order_items` where `order`.`id` = `order_item`.`order_id`
)

whereHas

whereHas and orWhereHas methods to put where conditions on your has queries. These methods allow you to add customized constraints to a relationship constraint.

Order::whereHas('orderItems', function($query) {
   $query->where('status', 1);
})->get();

Laravel change this code to one SQL:

select * from `orders` where exists (
    select * 
    from `order_items` 
    where `orders`.`id` = `order_items`.`order_id` and `status` = 1
)

you can do this in different ways:

1. Setting a timeout in the web service caller from code (not 100% sure but I think I have seen this done);
2. Setting a timeout in the constructor of the web service proxy in the web references;
3. Setting a timeout in the server side, web.config of the web service application.

see here for more details on the second case:

http://msdn.microsoft.com/en-us/library/ff647786.aspx#scalenetchapt10_topic14

and here for details on the last case:

How to increase the timeout to a web service request?

While defining multi-line triggers one has to change the delimiter as semicolon will be taken by MySQL compiler as end of trigger and generate error. e.g.

DELIMITER //
CREATE TRIGGER `MyTable_UPDATE` BEFORE UPDATE ON `MyTable`
FOR EACH ROW BEGIN
        -- Set the udpate date
    Set new.UpdateDate = now();
END//
DELIMITER ;

Modern browsers support a Content Security Policy or CSP. This is the highest level of web security and strongly recommended if you can apply it because it completely blocks all XSS attacks.

Both of your suggestions break with CSP enabled because they allow inline Javascript (which could be injected by a hacker) to execute in your page.

The best practice is to subscribe to the event in Javascript, as in Konrad Rudolph's answer.

My favorite answer is as what the first sentence in this thread suggested. Use an Adjacency List to maintain the hierarchy and use Nested Sets to query the hierarchy.

The problem up until now has been that the coversion method from an Adjacecy List to Nested Sets has been frightfully slow because most people use the extreme RBAR method known as a "Push Stack" to do the conversion and has been considered to be way to expensive to reach the Nirvana of the simplicity of maintenance by the Adjacency List and the awesome performance of Nested Sets. As a result, most people end up having to settle for one or the other especially if there are more than, say, a lousy 100,000 nodes or so. Using the push stack method can take a whole day to do the conversion on what MLM'ers would consider to be a small million node hierarchy.

I thought I'd give Celko a bit of competition by coming up with a method to convert an Adjacency List to Nested sets at speeds that just seem impossible. Here's the performance of the push stack method on my i5 laptop.

Duration for     1,000 Nodes = 00:00:00:870 
Duration for    10,000 Nodes = 00:01:01:783 (70 times slower instead of just 10)
Duration for   100,000 Nodes = 00:49:59:730 (3,446 times slower instead of just 100) 
Duration for 1,000,000 Nodes = 'Didn't even try this'

And here's the duration for the new method (with the push stack method in parenthesis).

Duration for     1,000 Nodes = 00:00:00:053 (compared to 00:00:00:870)
Duration for    10,000 Nodes = 00:00:00:323 (compared to 00:01:01:783)
Duration for   100,000 Nodes = 00:00:03:867 (compared to 00:49:59:730)
Duration for 1,000,000 Nodes = 00:00:54:283 (compared to something like 2 days!!!)

Yes, that's correct. 1 million nodes converted in less than a minute and 100,000 nodes in under 4 seconds.

You can read about the new method and get a copy of the code at the following URL. http://www.sqlservercentral.com/articles/Hierarchy/94040/

I also developed a "pre-aggregated" hierarchy using similar methods. MLM'ers and people making bills of materials will be particularly interested in this article. http://www.sqlservercentral.com/articles/T-SQL/94570/

If you do stop by to take a look at either article, jump into the "Join the discussion" link and let me know what you think.

As an alternative, Bintray provides free hosting of maven repositories. That's probably a good alternative to Sonatype OSS and Maven Central if you absolutely don't want to rename the groupId. But please, at least make an effort to get your changes integrated upstream or rename and publish to Central. It makes it much easier for others to use your fork.

Nothing helped me except this way

A usefull procedure for oracle databases without using exeptions (under circumstances you have to replace user_tables with dba_tables and/or constrain the tablespace in the query):

create or replace procedure NG_DROP_TABLE(tableName varchar2)
is
   c int;
begin
   select count(*) into c from user_tables where table_name = upper(tableName);
   if c = 1 then
      execute immediate 'drop table '||tableName;
   end if;
end;

Probably one of the indexes is wrong, either the inner one or the outer one.

I suspect you mean to say [0] where you say [1] and [1] where you say [2]. Indexes are 0-based in Python.

In addition to the answers above, you can check the type of object using type(plt.subplots()) which returns a tuple, on the other hand, type(plt.subplot()) returns matplotlib.axes._subplots.AxesSubplot which you can't unpack.

This answer is not something new. It's similar to what @andy_t has mentioned. But I use the below pattern for two reasons.

1. Clean implementation with No external npm dependencies

2. Merge the default config settings with the environment based settings.

Javascript implementation

const settings = {
    _default: {
       timeout: 100
       baseUrl: "http://some.api/",
    },
    production: {
       baseUrl: "http://some.prod.api/",
    },
}
// If you are not using ECMAScript 2018 Standard
// https://stackoverflow.com/a/171256/1251350
module.exports = { ...settings._default, ...settings[process.env.NODE_ENV] }

I usually use typescript in my node project. Below is my actual implementation copy-pasted.

Typescript implementation

const settings: { default: ISettings, production: any } = {
    _default: {
        timeout: 100,
        baseUrl: "",
    },
    production: {
        baseUrl: "",
    },
}

export interface ISettings {
    baseUrl: string
}

export const config = ({ ...settings._default, ...settings[process.env.NODE_ENV] } as ISettings)

Don't forget that you can always cut and paste into the minibuffer.

So you can just copy a newline character (or any string) from your buffer, then yank it when prompted for the replacement text.

Same as matt said. The "SQL Server(SQLEXPRESS)" was stopped. Enabled it by opening Control Panel > Administrative Tools > Services, right-clicking on the "SQL Server(SQLEXPRESS)" service and selecting "Start" from the available options. Could connect fine after that.

On windows, simply pressing 'q' on the keyboard quits this screen. I got it when I was reading help using '!help' or simply 'help' and 'enter', from the DOS prompt.

Happy Coding :-)

mktemp is probably the most versatile, especially if you plan to work with the file for a while.

You can also use a process substitution operator <() if you only need the file temporarily as input to another command, e.g.:

$ diff <(echo hello world) <(echo foo bar)

Just console log your error stack. You can then know how are you being called

const hello = () => {_x000D_
  console.log(new Error('I was called').stack)_x000D_
}_x000D_
_x000D_
const sello = () => {_x000D_
  hello()_x000D_
}_x000D_
_x000D_
sello()

If you are not giving export default then it throws an error. check if you have given module.exports = Speaker; //spelling mistake here you have written exoprts and check in all the modules whether you have exported correct.

I think you have to make some required configuration to start and run IE properly. You can find the guide at: https://github.com/SeleniumHQ/selenium/wiki/InternetExplorerDriver

I had the same problem and none of the above answers worked. If you go into the settings (CTRL + ALT + s) and search for project interpreter you will see all of the installed packages. Click the + button at the top right and search for xlrd, then click install package at the bottom left.

I had already done the "pip install xlrd" command from the file location of my python.exe before this, so you may need to do that as well. (you can find the file location by searching it in windows search bar and right click -> open file location, then type cmd into the file explorer address bar)

You need to stringify the json, not calling toString

var buf = Buffer.from(JSON.stringify(obj));

And for converting string to json obj :

var temp = JSON.parse(buf.toString());

The problem comes from a misunderstanding of what variables are in Python. If you're used to most traditional languages, you have a mental model of what happens in the following sequence:

a = 1
a = 2

You believe that a is a memory location that stores the value 1, then is updated to store the value 2. That's not how things work in Python. Rather, a starts as a reference to an object with the value 1, then gets reassigned as a reference to an object with the value 2. Those two objects may continue to coexist even though a doesn't refer to the first one anymore; in fact they may be shared by any number of other references within the program.

When you call a function with a parameter, a new reference is created that refers to the object passed in. This is separate from the reference that was used in the function call, so there's no way to update that reference and make it refer to a new object. In your example:

def __init__(self):
    self.variable = 'Original'
    self.Change(self.variable)

def Change(self, var):
    var = 'Changed'

self.variable is a reference to the string object 'Original'. When you call Change you create a second reference var to the object. Inside the function you reassign the reference var to a different string object 'Changed', but the reference self.variable is separate and does not change.

The only way around this is to pass a mutable object. Because both references refer to the same object, any changes to the object are reflected in both places.

def __init__(self):         
    self.variable = ['Original']
    self.Change(self.variable)

def Change(self, var):
    var[0] = 'Changed'

<script>
    const geocodeArr = JSON.parse('{{ geocode | tojson }}');
    console.log(geocodeArr);
</script>

This uses jinja2 to turn the geocode tuple into a json string, and then the javascript JSON.parse turns that into a javascript array.

Your inputs lack one important information of device dimension. Suppose now popular phone is 6 inch(the diagonal of the display), you will have following results

DPI: Dots per inch - number of dots(pixels) per segment(line) of 1 inch. DPI=Diagonal/Device size

Scaling Ratio= Real DPI/160. 160 is basic density (MHDPI)

DP: (Density-independent Pixel)=1/160 inch, think of it as a measurement unit

Masking means to keep/change/remove a desired part of information. Lets see an image-masking operation; like- this masking operation is removing any thing that is not skin-

We are doing AND operation in this example. There are also other masking operators- OR, XOR.

Bit-Masking means imposing mask over bits. Here is a bit-masking with AND-

     1 1 1 0 1 1 0 1   [input]
(&)  0 0 1 1 1 1 0 0    [mask]
------------------------------
     0 0 1 0 1 1 0 0  [output]

So, only the middle 4 bits (as these bits are 1 in this mask) remain.

Lets see this with XOR-

     1 1 1 0 1 1 0 1   [input]
(^)  0 0 1 1 1 1 0 0    [mask]
------------------------------
     1 1 0 1 0 0 0 1  [output]

Now, the middle 4 bits are flipped (1 became 0, 0 became 1).

So, using bit-mask we can access individual bits [examples]. Sometimes, this technique may also be used for improving performance. Take this for example-

bool isOdd(int i) {
    return i%2;
}

This function tells if an integer is odd/even. We can achieve the same result with more efficiency using bit-mask-

bool isOdd(int i) {
    return i&1;
}

Short Explanation: If the least significant bit of a binary number is 1 then it is odd; for 0 it will be even. So, by doing AND with 1 we are removing all other bits except for the least significant bit i.e.:

     55  ->  0 0 1 1 0 1 1 1   [input]
(&)   1  ->  0 0 0 0 0 0 0 1    [mask]
---------------------------------------
      1  <-  0 0 0 0 0 0 0 1  [output]

Had this happen intermittently, turns out I only had this issue when the list was scrolled after a 'load more' last item was clicked. If the list wasn't scrolled, everything worked fine.

After MUCH debugging, it was a bug on my part, but an inconsistency in the Android code also.

When the validation happens, this code is executed in ListView

        } else if (mItemCount != mAdapter.getCount()) {
            throw new IllegalStateException("The content of the adapter has changed but "
                    + "ListView did not receive a notification. Make sure the content of "

But when onChange happens it fires this code in AdapterView (parent of ListView)

    @Override
    public void onChanged() {
        mDataChanged = true;
        mOldItemCount = mItemCount;
        mItemCount = getAdapter().getCount();

Notice the way the Adapter is NOT guaranteed to be the Same!

In my case, since it was a 'LoadMoreAdapter' I was returning the WrappedAdapter in the getAdapter call (for access to the underlying objects). This resulted in the counts being different due to the extra 'Load More' item and the Exception being thrown.

I only did this because the docs make it seem like it's ok to do

ListView.getAdapter javadoc

Returns the adapter currently in use in this ListView. The returned adapter might not be the same adapter passed to setAdapter(ListAdapter) but might be a WrapperListAdapter.

You can write like

UILabel *reviews = [[UILabel alloc]initWithFrame:CGRectMake(14, 13,270,30)];//Set frame
reviews.numberOfLines=0;
reviews.textAlignment = UITextAlignmentLeft;
reviews.font = [UIFont fontWithName:@"Arial Rounded MT Bold" size:12];
reviews.textColor=[UIColor colorWithRed:0.0/255.0 green:0.0/255.0 blue:0.0/255.0 alpha:0.8]; 
reviews.backgroundColor=[UIColor clearColor];

You can calculate number of lines like that

CGSize maxlblSize = CGSizeMake(270,9999);
CGSize totalSize = [reviews.text sizeWithFont:reviews.font 
              constrainedToSize:maxlblSize lineBreakMode:reviews.lineBreakMode];

CGRect newFrame =reviews.frame;
newFrame.size.height = totalSize.height;
reviews.frame = newFrame;

CGFloat reviewlblheight = totalSize.height;

int lines=reviewlblheight/12;//12 is the font size of label

UILabel *lbl=[[UILabel alloc]init];

One can use base python for this. The code needs a function to flatten lists of lists:

def flatten(B):    # function needed for code below;
    A = []
    for i in B:
        if type(i) == list: A.extend(i)
        else: A.append(i)
    return A

Then one can run:

L = [[1,2,3],[4,5,6],[7,8,9,10]]

outlist =[]; templist =[[]]
for sublist in L:
    outlist = templist; templist = [[]]
    for sitem in sublist:
        for oitem in outlist:
            newitem = [oitem]
            if newitem == [[]]: newitem = [sitem]
            else: newitem = [newitem[0], sitem]
            templist.append(flatten(newitem))

outlist = list(filter(lambda x: len(x)==len(L), templist))  # remove some partial lists that also creep in;
print(outlist)

Output:

[[1, 4, 7], [2, 4, 7], [3, 4, 7], 
[1, 5, 7], [2, 5, 7], [3, 5, 7], 
[1, 6, 7], [2, 6, 7], [3, 6, 7], 
[1, 4, 8], [2, 4, 8], [3, 4, 8], 
[1, 5, 8], [2, 5, 8], [3, 5, 8], 
[1, 6, 8], [2, 6, 8], [3, 6, 8], 
[1, 4, 9], [2, 4, 9], [3, 4, 9], 
[1, 5, 9], [2, 5, 9], [3, 5, 9], 
[1, 6, 9], [2, 6, 9], [3, 6, 9], 
[1, 4, 10], [2, 4, 10], [3, 4, 10], 
[1, 5, 10], [2, 5, 10], [3, 5, 10], 
[1, 6, 10], [2, 6, 10], [3, 6, 10]]

It took a few tries, but I was able to get your jsFiddle to work (for Webkit only).

There's still an issue with the animation speed when the user re-enters the div.

Basically, just set the current rotation value to a variable, then do some calculations on that value (to convert to degrees), then set that value back to the element on mouse move and mouse enter.

Check out the jsFiddle: http://jsfiddle.net/4Vz63/46/

Check out this article for more information, including how to add cross-browser compatibility: http://css-tricks.com/get-value-of-css-rotation-through-javascript/

If the user exists you can get the user in user_object else user_object will be None.

try:
    user_object = User.objects.get(email = cleaned_info['username'])
except User.DoesNotExist:
    user_object = None
if user_object:
    # user exist
    pass
else:
    # user does not exist
    pass

Use git reset HEAD to reset the index without removing files. (If you only want to reset a particular file in the index, you can use git reset HEAD -- /path/to/file to do so.)

The pipe operator, in a shell, takes the stdout of the process on the left and passes it as stdin to the process on the right. It's essentially the equivalent of:

$ proc1 > proc1.out
$ proc2 < proc1.out
$ rm proc1.out

but instead it's $ proc1 | proc2, the second process can start getting data before the first is done outputting it, and there's no actual file involved.

After much figuring out, the following worked for me:

gradle test --tests "a.b.c.MyTestFile.mySingleTest"

I shared two solutions depending on your needs:

<style type="text/css" ref="stylesheet">
  .border-inside-box {
    border: 1px solid black;
  }
  .border-inside-box-v1 {
    outline: 1px solid black; /* 'border-radius' not available */
  }
  .border-outside-box-v2 {
    box-shadow: 0 0 0 1px black; /* 'border-style' not available (dashed, solid, etc) */
  }
</style>

example: https://codepen.io/danieldd/pen/gObEYKj

As of today, the answer does not work for me, but putting this at the top of the file does work:

/* eslint-disable @typescript-eslint/no-unused-vars */

It is important to know that at least in my case, the type of comment makes a difference. The previous comment works for me, but the following won't work:

// eslint-disable @typescript-eslint/no-unused-vars

A different way to handle such cases is to use formControl and subscribe to it's valueChanges when your component is initialized, which will allow you to use rxjs operators for advanced requirements like performing http requests, apply a debounce until user finish writing a sentence, take last value and omit previous, ...

import {Component, OnInit} from '@angular/core';
import { FormControl } from '@angular/forms';
import { debounceTime, distinctUntilChanged } from 'rxjs/operators';

@Component({
  selector: 'some-selector',
  template: `
    <input type="text" [formControl]="searchControl" placeholder="search">
  `
})
export class SomeComponent implements OnInit {
  private searchControl: FormControl;
  private debounce: number = 400;

  ngOnInit() {
    this.searchControl = new FormControl('');
    this.searchControl.valueChanges
      .pipe(debounceTime(this.debounce), distinctUntilChanged())
      .subscribe(query => {
        console.log(query);
      });
  }
}

In Parent Conponent -->

data : function(){
            return {
                siteEntered : false, 
            };
        },

In Child Component -->

this.$parent.$data.siteEntered = true;

Give 0777 to all files and directories starting from the current path :

chmod -R 0777 ./

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html> 

Just make a new folder inside C:\xampp\htdocs like C:\xampp\htdocs\test and place your index.php or whatever file in it. Access it by browsing localhost/test/

Good luck!

Use the project's root folder

Artisan comes with Laravel by default, if your php command works fine, then the only thing you need to do is to navigate to the project's root folder. The root folder is the parent folder of the app folder. For example:

cd c:\Program Files\xampp\htdocs\your-project-name

Now the php artisan list command should work fine, because PHP runs the file called artisan in the project's folder.

Install the framework

Keep in mind that Artisan runs scripts stored in the vendor folder, so if you installed Laravel without Composer, like downloading and extracting the Laravel GitHub repo, then you don't have the framework itself and you may get the following error when you try to use Artisan:

Could not open input file: artisan

To solve this you have to install the framework itself by running composer install in your project's root folder.

you could have a computed property that returns a boolean dependent on whatever criteria you need.

<input type="text" :disabled=isDisabled>

then put your logic in a computed property...

computed: {
  isDisabled() {
    // evaluate whatever you need to determine disabled here...
    return this.form.validated;
  }
}

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

Another minimalist Python solution without using numpy:

[0 if i < 0 else i for i in a]

No need to define any extra functions.

a = [1, 2, 3, -4, -5.23, 6]
[0 if i < 0 else i for i in a]

yields:

[1, 2, 3, 0, 0, 6]

file_get_contents() usually has permission issues. To avoid them, use:

function get_xml_from_url($url){
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

    $xmlstr = curl_exec($ch);
    curl_close($ch);

    return $xmlstr;
}

Example:

$xmlstr = get_xml_from_url('http://www.camara.gov.br/SitCamaraWS/Deputados.asmx/ObterDeputados');
$xmlobj = new SimpleXMLElement($xmlstr);
$xmlobj = (array)$xmlobj;//optional

On the server, try:

netstat -an 

and look to see if tcp port 22 is opened (use findstr in Windows or grep in Unix).

I followed the advice of Simon Gibbs in this answer and found it worked out fine - if you're in a hurry, the "Web Page Editor (optional)" package from the Eclipse update site does the trick.

For the Eclipse-challenged (me) Help > Install New Software > Work with > Expand Web, XML, and Java EE Development > Select "Web Page Editor (optional)" and "next-through" to completion.

You can use CSS to do the trick:

$("#yourElement").css({ top: '100px' });

The display:table family of CSS properties is mostly there so that HTML tables can be defined in terms of them. Because they're so intimately linked to a specific tag structure, they don't see much use beyond that.

If you were going to use these properties in your page, you would need a tag structure that closely mimicked that of tables, even though you weren't actually using the <table> family of tags. A minimal version would be a single container element (display:table), with direct children that can all be represented as rows (display:table-row), which themselves have direct children that can all be represented as cells (display:table-cell). There are other properties that let you mimic other tags in the table family, but they require analogous structures in the HTML. Without this, it's going to be very hard (if not impossible) to make good use of these properties.

That is the best way to check it. You could write a helper method to do it:

public static boolean isNullOrEmpty( final Collection< ? > c ) {
    return c == null || c.isEmpty();
}

public static boolean isNullOrEmpty( final Map< ?, ? > m ) {
    return m == null || m.isEmpty();
}

git reset --hard 1258f0d0aae

But be careful, if the descendant commits between 1258f0d0aae and HEAD are not referenced in other branches it'll be tedious (but not impossible) to recover them, so you'd better to create a "backup" branch at current HEAD, checkout master, and reset to the commit you want.

Also, be sure that you don't have uncommitted changes before a reset --hard, they will be truly lost (no way to recover).

The problem lies on your proxy. Because the location provider of your install package creates its own certificate and does not buy a verified one from an accepted authority, your proxy does not allow access to the targeted host. I assume that you bypass the proxy when using the Chrome Browser. So there is no checking.

There are some solutions to this problem. But all imply that you trust the package provider.

Possible solutions:

1. As mentioned in other answers you can make an http:// access which may bypass your proxy. That's a bit dangerous, because the man in the middle can inject malware into you downloads.
2. The wget suggests you to use a flag --no-check-certificate. This will add a proxy directive to your request. The proxy, if it understands the directive, does not check if the servers certificate is verified by an authority and passes the request. Perhaps there is a config with npm that does the same as the wget flag.
3. You configure your proxy to accept CA npm. I don't know your proxy, so I can't give you a hint.

Install Mylyn connector for GitHub from this update site, it provides great integration: you can directly import your repositories using Import > Projects from Git > GitHub. You can set the default repository folder in Preferences > Git.

It's not good to change the scope of your application dependencies. Putting the dependency as compile, will provide the dependency also in your artifact that will be installed somewere. The best think to do is configure the RUN configuration of your sping boot application by specifying as stated in documentation :

"Include dependencies with 'Provided' scope" "Enable this option to add dependencies with the Provided scope to the runtime classpath."

Try: $('#mytable').attr('offsetTop')

Try the following code :

$config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http");
$config['base_url'] .= "://".$_SERVER['HTTP_HOST'];
$config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
echo $config['base_url'];

Hide the input-file element and create a visible button that will trigger the click event of that input-file.

Try this:

CSS

#file { width:0; height:0; } 

HTML:

<input type='file' id='file' name='file' />
<button id='btn-upload'>Upload</button>

JAVASCRIPT(jQuery):

$(function(){
    $('#btn-upload').click(function(e){
        e.preventDefault();
        $('#file').click();}
    );
});

I think the code is something like:

int rgb = red;
rgb = (rgb << 8) + green;
rgb = (rgb << 8) + blue;

Also, I believe you can get the individual values using:

int red = (rgb >> 16) & 0xFF;
int green = (rgb >> 8) & 0xFF;
int blue = rgb & 0xFF;

For anyone using nativescript and facing this issue: you can add

compileSdkVersion 26
buildToolsVersion '26.0.1'

in App_Resources/Android/app.gradle (under android {)

Then run tns platform remove android and tns build android in your project root.

I think you can use:

pygame.time.delay(delayTime)

in which delayTime is in milliseconds.

Put it before events.

You're looking for:

.is(':visible')

Although you should probably change your selector to use jQuery considering you're using it in other places anyway:

if($('#testElement').is(':visible')) {
    // Code
}

It is important to note that if any one of a target element's parent elements are hidden, then .is(':visible') on the child will return false (which makes sense).

jQuery 3

:visible has had a reputation for being quite a slow selector as it has to traverse up the DOM tree inspecting a bunch of elements. There's good news for jQuery 3, however, as this post explains (Ctrl + F for :visible):

Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!

Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.

Expanding even further to your specific use case, there is a built in jQuery function called $.fadeToggle():

function toggleTestElement() {
    $('#testElement').fadeToggle('fast');
}

Follow this method if problem comes when working with angular2+ projects

I was looking for a solution when i got this error, and it got me here. But this question seems to be specific but the error is not, its a generic error. This is a common error for angular developers dealing with Internet Explorer.

I had the same issue while working with angular 2+, and it got resolved just by few simple steps.

In Angular latest versions, there are come commented codes in the polyfills.ts shows all the polyfills required for the smooth running in Internet Explorer versions IE09,IE10 and IE11

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
//import 'core-js/es6/symbol';
//import 'core-js/es6/object';
//import 'core-js/es6/function';
//import 'core-js/es6/parse-int';
//import 'core-js/es6/parse-float';
//import 'core-js/es6/number';
//import 'core-js/es6/math';
//import 'core-js/es6/string';
//import 'core-js/es6/date';
//import 'core-js/es6/array';
//import 'core-js/es6/regexp';
//import 'core-js/es6/map';
//import 'core-js/es6/weak-map';
//import 'core-js/es6/set';

Uncomment the codes and it would work perfectly in IE browsers

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
import 'core-js/es6/symbol';
import 'core-js/es6/object';
import 'core-js/es6/function';
import 'core-js/es6/parse-int';
import 'core-js/es6/parse-float';
import 'core-js/es6/number';
import 'core-js/es6/math';
import 'core-js/es6/string';
import 'core-js/es6/date';
import 'core-js/es6/array';
import 'core-js/es6/regexp';
import 'core-js/es6/map';
import 'core-js/es6/weak-map';
import 'core-js/es6/set';

But you might see a performance drop in IE browsers compared to others :(

In my case I was miscalculating the Content-Length that I advertised in the header. I was serving Range-Requests for files and I mistakenly published the filesize in Content-Length.

I fixed the problem by setting Content-Length to the actual range that I was sending back to the browser.

So in case I am answering to a normal request I set the Content-Length to the filesize. In case I am answering to a range-request I set the Content-Length to the actualy length of the requested range.

Solution for change TextView width to wrap content.

textView.getLayoutParams().width = ViewGroup.LayoutParams.WRAP_CONTENT; 
textView.requestLayout();  
// Call requestLayout() for redraw your TextView when your TextView is already drawn (laid out) (eg: you update TextView width when click a Button). 
// If your TextView is drawing you may not need requestLayout() (eg: you change TextView width inside onCreate()). However if you call it, it still working well => for easy: always use requestLayout()

// Another useful example
// textView.getLayoutParams().width = 200; // For change `TextView` width to 200 pixel

Combining answers from @owencm and @Chazt3n, this function will allow download of text from IE11, Firefox, and Chrome. (Sorry, I don't have access to Safari or Opera, but please add a comment if you try and it works.)

initiate_user_download = function(file_name, mime_type, text) {
    // Anything but IE works here
    if (undefined === window.navigator.msSaveOrOpenBlob) {
        var e = document.createElement('a');
        var href = 'data:' + mime_type + ';charset=utf-8,' + encodeURIComponent(text);
        e.setAttribute('href', href);
        e.setAttribute('download', file_name);
        document.body.appendChild(e);
        e.click();
        document.body.removeChild(e);
    }
    // IE-specific code
    else {
        var charCodeArr = new Array(text.length);
        for (var i = 0; i < text.length; ++i) {
            var charCode = text.charCodeAt(i);
            charCodeArr[i] = charCode;
        }
        var blob = new Blob([new Uint8Array(charCodeArr)], {type: mime_type});
        window.navigator.msSaveOrOpenBlob(blob, file_name);
    }
}

// Example:
initiate_user_download('data.csv', 'text/csv', 'Sample,Data,Here\n1,2,3\n');

This works for me.

@{ var dic = new Dictionary<string, string>() { { "checked", "" } }; }
@Html.RadioButtonFor(_ => _.BoolProperty, true, (@Model.BoolProperty)? dic: null) Yes
@Html.RadioButtonFor(_ => _.BoolProperty, false, ([email protected])? dic: null) No

0755 = User:rwx Group:r-x World:r-x

0750 = User:rwx Group:r-x World:--- (i.e. World: no access)

r = read
w = write
x = execute (traverse for directories)

Unfortunately, all answers so far do not take into account that "a" must not be considered equal to "A" when it comes to sorting.

String[] array = {"b", "A", "C", "B", "a"};

// Approach 1
Arrays.sort(array);
// array is [A, B, C, a, b]

// Approach 2
Arrays.sort(array, String.CASE_INSENSITIVE_ORDER);
// array is [A, a, b, B, C]

// Approach 3
Arrays.sort(array, java.text.Collator.getInstance());
// array is [a, A, b, B, C]

In approach 1 any lower case letters are considered greater than any upper case letters.

Approach 2 makes it worse, since CASE_INSENSITIVE_ORDER considers "a" and "A" equal (comparation result is 0). This makes sorting non-deterministic.

Approach 3 (using a java.text.Collator) is IMHO the only way of doing it correctly, since it considers "a"and "A" not equal, but puts them in the correct order according to the current (or any other desired) Locale.

Also $( "#container" ).find( "div.robotarm" );
is equal to: $( "div.robotarm", "#container" )

int[] anArray = { 1, 5, 2, 7 };
// Finding max
int m = anArray.Max();

// Positioning max
int p = Array.IndexOf(anArray, m);

This variant is better because you could not know whether file exists or not. You should send correct header when you know for certain that you can read contents of your file. Also, if you have branches of code that does not finish with '.end()', browser will wait until it get them. In other words, your browser will wait a long time.

var fs = require("fs");
var filename = "./index.html";

function start(resp) {

    fs.readFile(filename, "utf8", function(err, data) {
        if (err) {
            // may be filename does not exists?
            resp.writeHead(404, {
                'Content-Type' : 'text/html'
            });
            // log this error into browser
            resp.write(err.toString());
            resp.end();
        } else {

            resp.writeHead(200, {
                "Content-Type": "text/html"
            });      
            resp.write(data.toString());
            resp.end();
        }
    });
}

Change position

position:fixed;
overflow: hidden;

to

position:absolute;
overflow:scroll;

This function works in any OS (Unix, Linux, macOS, and Windows)
Python 2 and Python 3

import platform    # For getting the operating system name
import subprocess  # For executing a shell command

def clear_screen():
    """
    Clears the terminal screen.
    """

    # Clear command as function of OS
    command = "cls" if platform.system().lower()=="windows" else "clear"

    # Action
    return subprocess.call(command) == 0

In windows the command is cls, in unix-like systems the command is clear.
platform.system() returns the platform name. Ex. 'Darwin' for macOS.
subprocess.call() performs a system call. Ex. subprocess.call(['ls','-l'])

As to UTF-8 is multibite characters string and so you get some problems to work and it's a bad idea/ Instead use normal Unicode.

So by my opinion best is use ordinary ASCII char text with some codding set. Need to use Unicode if you use more than 2 sets of different symbols (languages) in single.

It's rather rare case. In most cases enough 2 sets of symbols. For this common case use ASCII chars, not Unicode.

Effect of using multibute chars like UTF-8 you get only China traditional, arabic or some hieroglyphic text. It's very very rare case!!!

I don't think there are many peoples needs that. So never use UTF-8!!! It's avoid strong headache of manipulate such strings.

?library

and you will see:

library(package) and require(package) both load the package with name package and put it on the search list. require is designed for use inside other functions; it returns FALSE and gives a warning (rather than an error as library() does by default) if the package does not exist. Both functions check and update the list of currently loaded packages and do not reload a package which is already loaded. (If you want to reload such a package, call detach(unload = TRUE) or unloadNamespace first.) If you want to load a package without putting it on the search list, use requireNamespace.

You can't compare arrays directly like this

array1==array2

You should compare them char-by-char; for this you can use a function and return a boolean (True:1, False:0) value. Then you can use it in the test condition of the while loop.

Try this:

#include <stdio.h>
int checker(char input[],char check[]);
int main()
{
    char input[40];
    char check[40];
    int i=0;
    printf("Hello!\nPlease enter a word or character:\n");
    scanf("%s",input);
    printf("I will now repeat this until you type it back to me.\n");
    scanf("%s",check);

    while (!checker(input,check))
    {
        printf("%s\n", input);
        scanf("%s",check);
    }

    printf("Good bye!");

    return 0;
}

int checker(char input[],char check[])
{
    int i,result=1;
    for(i=0; input[i]!='\0' || check[i]!='\0'; i++) {
        if(input[i] != check[i]) {
            result=0;
            break;
        }
    }
    return result;
}

Use a div for your divider. It will always be centered vertically regardless to whether left and right divs are equal in height. You can reuse it anywhere on your site.

.divider{
    position:absolute;
    left:50%;
    top:10%;
    bottom:10%;
    border-left:1px solid white;
}
