Solved an almost identical problem, by adding these lines to the standard PHPMailer configuration. Works like a charm.

$mail->SMTPKeepAlive = true;   
$mail->Mailer = “smtp”; // don't change the quotes!

Came across this code (from Simon Chen) while researching a solution here, https://webolio.wordpress.com/2008/03/02/phpmailer-and-smtp-on-1and1-shared-hosting/#comment-89

It can be useful also to add the option --no-desktop to avoid launching several buffers saved.

Neither. You should separate content and presentation, giving your HTML code logical codes. Think of it this way; to a blind person, or on a browser that cannot display colors, what is left of your code? Why do you want it to be red?

Most probably, your decision to make text red is because you want to give it emphasis. So your HTML code should be:

<em>test</em>

This way, even non-visual browsers can make sure they give the text emphasis in one way or another.

Next step is to make the text red. But you don't want to add the color code everywhere, much more efficient to just add it once:

<style>
  em { color: red; }
</style>

This way, all emphasized code on your website becomes red, making it more constant.

Its late, yet it's worth your time nothing that, there are some differences in browser level implementation of focusin and focusout events and react synthetic onFocus and onBlur. focusin and focusout actually bubble, while onFocus and onBlur dont. So there is no exact same implementation for focusin and focusout as of now for react. Anyway most cases will be covered in onFocus and onBlur.

Check out SQL For Smarties. I thought I was pretty good with SQL too, until I read that book... Goes into tons of depth, talks about things I've not seen elsewhere (I.E. difference between 3'rd and 4'th normal form, Boyce Codd Normal Form, etc)...

Got best solution for this from tonyspiro

function getBetween($content,$start,$end){
   $r = explode($start, $content);
   if (isset($r[1])){
       $r = explode($end, $r[1]);
       return $r[0];
   }
   return '';
}

This post helped me today, but I had to experiment to do what I needed. Here is what I found.

Should you want to add more complex time periods, for example 1 year and 15 days, you can use

UPDATE tablename SET datefieldname = curdate() + INTERVAL 15 DAY + INTERVAL 1 YEAR;

I found that using DATE_ADD doesn't allow for adding more than one interval. And there is no YEAR_DAYS interval keyword, though there are others that combine time periods. If you are adding times, use now() rather than curdate().

This should do it:

WHERE `date` = CURDATE() - INTERVAL 1 DAY

>>> dict(a=2,b=4)
{'a': 2, 'b': 4}

Will add the value in the python dictionary.

use this full code

          Intent callIntent = new Intent(Intent.ACTION_DIAL);
          callIntent.setData(Uri.parse("tel:"+Uri.encode(PhoneNum.trim())));
          callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
          startActivity(callIntent);     

Try switching to a LinearLayout instead of RelativeLayout. I was targeting the 3.0 Honeycomb api when testing.

public class FragmentDialog extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Button button = (Button) findViewById(R.id.show);
    button.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            showDialog();
        }
    });
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
}

void showDialog() {
    FragmentTransaction ft = getFragmentManager().beginTransaction();
    DialogFragment newFragment = MyDialogFragment.newInstance();
    newFragment.show(ft, "dialog");
}

public static class MyDialogFragment extends DialogFragment {

    static MyDialogFragment newInstance() {
        MyDialogFragment f = new MyDialogFragment();
        return f;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment_dialog, container, false);
        return v;
    }

}
}

and the layouts: fragment_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:minWidth="1000dp"  
    android:minHeight="1000dp"> 
 </LinearLayout> 

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"
    android:background="#ffffff">
    <Button android:id="@+id/show"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:layout_weight="0"
        android:text="show">
    </Button>
</LinearLayout>

An even easier and more shorthand version would be:

if (!x) {
   //Undefined
}

OR

if (typeof x !== "undefined") {
    //Do something since x is defined.
}

Create a configuration file and put your entries there.

SERVER_PORT=10000     
THREAD_POOL_COUNT=3     
ROOT_DIR=/home/   

You can load this file using Properties.load(fileName) and retrieved values you get(key);

Its a trick not a proper method.

• Create a Relative layout.
• Define your facebook_botton.
• Also define your custom design button.
• Overlap them.

<RelativeLayout android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_marginTop="30dp">
    <com.facebook.login.widget.LoginButton
    xmlns:facebook="http://schemas.android.com/apk/res-auto"
    android:id="@+id/login_button"
    android:layout_width="300dp"
    android:layout_height="100dp"
    android:paddingTop="15dp"
    android:paddingBottom="15dp" />
    <LinearLayout
    android:id="@+id/llfbSignup"
    android:layout_width="300dp"
    android:layout_height="50dp"
    android:background="@drawable/facebook"
    android:layout_gravity="center_horizontal"
    android:orientation="horizontal">
    <ImageView
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:src="@drawable/facbk"
    android:layout_gravity="center_vertical"
    android:layout_marginLeft="10dp" />
    <View
    android:layout_width="1dp"
    android:layout_height="match_parent"
    android:background="@color/fullGray"
    android:layout_marginLeft="10dp"/>
    <com.yadav.bookedup.fonts.GoutamBold
    android:layout_width="240dp"
    android:layout_height="50dp"
    android:text="Sign Up via Facebook"
    android:gravity="center"
    android:textColor="@color/white"
    android:textSize="18dp"
    android:layout_gravity="center_vertical"
    android:layout_marginLeft="10dp"/>
    </LinearLayout>
</RelativeLayout>

Not sure if it's what you mean, but you can do this:

plot(1:10, xaxt = "n", xlab='Some Letters')
axis(1, at=1:10, labels=letters[1:10])

which then gives you the graph:

Use a comma to specify two (or more) different rules:

@media screen and (max-width: 995px), 
       screen and (max-height: 700px) {
  ...
}

From https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries

Commas are used to combine multiple media queries into a single rule. Each query in a comma-separated list is treated separately from the others. Thus, if any of the queries in a list is true, the entire media statement returns true. In other words, lists behave like a logical or operator.

import socket
from threading import *

serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = "192.168.1.3"
port = 8000
print (host)
print (port)
serversocket.bind((host, port))

class client(Thread):
    def __init__(self, socket, address):
        Thread.__init__(self)
        self.sock = socket
        self.addr = address
        self.start()

    def run(self):
        while 1:
            print('Client sent:', self.sock.recv(1024).decode())
            self.sock.send(b'Oi you sent something to me')

serversocket.listen(5)
print ('server started and listening')
while 1:
    clientsocket, address = serversocket.accept()
    client(clientsocket, address)

This is a very VERY simple design for how you could solve it. First of all, you need to either accept the client (server side) before going into your while 1 loop because in every loop you accept a new client, or you do as i describe, you toss the client into a separate thread which you handle on his own from now on.

Instead of:

var host = req.get('host');
var origin = req.get('origin');

you can also use:

var host = req.headers.host;
var origin = req.headers.origin;

You'll get that error once your numbers are greater than sys.maxsize:

>>> p = [sys.maxsize]
>>> preds[0] = p
>>> p = [sys.maxsize+1]
>>> preds[0] = p
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long

You can confirm this by checking:

>>> import sys
>>> sys.maxsize
2147483647

To take numbers with larger precision, don't pass an int type which uses a bounded C integer behind the scenes. Use the default float:

>>> preds = np.zeros((1, 3))

<< is a binary shift, shifting 1 to the left 8 places.

4'b0001 << 1 => 4'b0010

>> is a binary right shift adding 0's to the MSB.
>>> is a signed shift which maintains the value of the MSB if the left input is signed.

4'sb1011 >>  1 => 0101
4'sb1011 >>> 1 => 1101

Three ways to indicate left operand is signed:

module shift;
  logic        [3:0] test1 = 4'b1000;
  logic signed [3:0] test2 = 4'b1000;

  initial begin
    $display("%b", $signed(test1) >>> 1 ); //Explicitly set as signed
    $display("%b", test2          >>> 1 ); //Declared as signed type
    $display("%b", 4'sb1000       >>> 1 ); //Signed constant
    $finish;
  end
endmodule

For the same solution I was looking for Angularjs directive with ng-Model.
Here is the code that resolve the problem.

    myApp.directive('zipcodeformatter', function () {
    return {
        restrict: 'A', // only activate on element attribute
        require: '?ngModel', // get a hold of NgModelController
        link: function (scope, element, attrs, ngModel) {

            scope.$watch(attrs.ngModel, function (v) {
                if (v) {
                    console.log('value changed, new value is: ' + v + ' ' + v.length);
                    if (v.length > 5) {
                        var newzip = v.replace("-", '');
                        var str = newzip.substring(0, 5) + '-' + newzip.substring(5, newzip.length);
                        element.val(str);

                    } else {
                        element.val(v);
                    }

                }

            });

        }
    };
});

Here is a working solution (just tried out with MySQL 5.0 on Solaris):

DELIMITER $$

DROP PROCEDURE IF EXISTS upgrade_database_1_0_to_2_0 $$
CREATE PROCEDURE upgrade_database_1_0_to_2_0()
BEGIN

-- rename a table safely
IF NOT EXISTS( (SELECT * FROM information_schema.COLUMNS WHERE TABLE_SCHEMA=DATABASE()
        AND TABLE_NAME='my_old_table_name') ) THEN
    RENAME TABLE 
        my_old_table_name TO my_new_table_name,
END IF;

-- add a column safely
IF NOT EXISTS( (SELECT * FROM information_schema.COLUMNS WHERE TABLE_SCHEMA=DATABASE()
        AND COLUMN_NAME='my_additional_column' AND TABLE_NAME='my_table_name') ) THEN
    ALTER TABLE my_table_name ADD my_additional_column varchar(2048) NOT NULL DEFAULT '';
END IF;

END $$

CALL upgrade_database_1_0_to_2_0() $$

DELIMITER ;

On a first glance it probably looks more complicated than it should, but we have to deal with following problems here:

• IF statements only work in stored procedures, not when run directly, e.g. in mysql client
• more elegant and concise SHOW COLUMNS does not work in stored procedure so have to use INFORMATION_SCHEMA
• the syntax for delimiting statements is strange in MySQL, so you have to redefine the delimiter to be able to create stored procedures. Do not forget to switch the delimiter back!
• INFORMATION_SCHEMA is global for all databases, do not forget to filter on TABLE_SCHEMA=DATABASE(). DATABASE() returns the name of the currently selected database.

Yes, it is possible to write and call a function nested in another function.

Try this:

function A(){
   B(); //call should be B();
   function B(){

   }
}

This command will give you postgres port number

 \conninfo

If postgres is running on Linux server, you can also use the following command

sudo netstat -plunt |grep postgres

OR (if it comes as postmaster)

sudo netstat -plunt |grep postmaster

and you will see something similar as this

tcp        0      0 127.0.0.1:5432          0.0.0.0:*               LISTEN      140/postgres
tcp6       0      0 ::1:5432                :::*                    LISTEN      140/postgres

in this case, port number is 5432 which is also default port number

For me this worked after I downloaded AJAX Unobtrusive library via NuGet :

 Search and install via NuGet Packages:   Microsoft.jQuery.Unobtrusive.Ajax

Than add in the view the references to jquery and AJAX Unobtrusive:

@Scripts.Render("~/bundles/jquery")
<script src="~/Scripts/jquery.unobtrusive-ajax.min.js"> </script>

Next the Ajax ActionLink and the div were we want to render the results:

@Ajax.ActionLink(
    "Click Here to Load the Partial View", 
    "ActionName", 
    null, 
    new AjaxOptions { UpdateTargetId = "toUpdate" }
)

<div id="toUpdate"></div>

I ran into this error after my client PC crashed, the jest --watch command I was running on the server persisted, and I tried to run jest --watch again.

The addition to /etc/sysctl.conf described in the answers above worked around this issue, but it was also important to find my old process via ps aux | grep node and kill it.

This sample code should work:

var http = require('http');
var options = {method: 'HEAD', host: 'stackoverflow.com', port: 80, path: '/'};
var req = http.request(options, function(res) {
    console.log(JSON.stringify(res.headers));
  }
);
req.end();

I help develop the Colectica for Excel addin, which opens SPSS and Stata data files in Excel. This does not require ODBC configuration; it reads the file and then inserts the data and metadata into your worksheet.

The addin is downloadable from http://www.colectica.com/software/colecticaforexcel

Try below code:

public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));// set transparent in window background

        View _v = inflater.inflate(R.layout.some_you_layout, container, false);

        //load animation
        //Animation transition_in_view = AnimationUtils.loadAnimation(getContext(), android.R.anim.fade_in);// system animation appearance
        Animation transition_in_view = AnimationUtils.loadAnimation(getContext(), R.anim.customer_anim);//customer animation appearance

        _v.setAnimation( transition_in_view );
        _v.startAnimation( transition_in_view );
        //really beautiful
        return _v;

    }

Create the custom Anim.: res/anim/customer_anim.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

    <translate
        android:duration="500"
        android:fromYDelta="100%"
        android:toYDelta="-7%"/>
    <translate
        android:duration="300"
        android:startOffset="500"
        android:toYDelta="7%" />
    <translate
        android:duration="200"
        android:startOffset="800"
        android:toYDelta="0%" />

</set>

You must add setActionCommand to the JRadioButton then just do:

String entree = entreeGroup.getSelection().getActionCommand();

Example:

java = new JRadioButton("Java");
java.setActionCommand("Java");
c = new JRadioButton("C/C++");
c.setActionCommand("c");
System.out.println("Selected Radio Button: " + 
                    buttonGroup.getSelection().getActionCommand());

I don't know if there's a way to get a clean build via the UI, but it's easy to do from the commandline using gradle wrapper. From the root directory of your project:

./gradlew clean 

Ahhh, the stupid linesize ... Here is what I do in my profile.sql - works only on unixes:

echo SET LINES $(tput cols) > $HOME/.login_tmp.sql
@$HOME/.login_tmp.sql

if you find an equivalent for tput on Windows, it might work there as well

Note that regexp or function approaches are several times slower than plain sql condition.

So some heuristic workarounds with limited applicability make sence for huge scans.

There is a solution for cases when you know for sure that non-numeric values would contain some alphabetic letters:

select case when upper(dummy)=lower(dummy) then '~numeric' else '~alpabetic' end from dual

And if you know some letter would be always present in non-numeric cases:

select case when instr(dummy, 'X')>0 then '~alpabetic' else '~numeric' end from dual

When numeric cases would always contain zero:

select case when instr(dummy, '0')=0 then '~alpabetic' else '~numeric' end from dual

Just include this line at the end of function and the Problem is solved easily!

document.getElementById("btnsubmit").value = "";

Please try this one works for me:

<ImageView android:id="@+id/image_view"     
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:adjustViewBounds="true"  
  android:maxWidth="60dp" 
  android:layout_gravity="center" 
  android:maxHeight="60dp"  
  android:scaleType="fitCenter"  
  android:src="@drawable/icon"  
  /> 

A little bit off topic but useful is the pythonic numpy approach. Its robust and fast but just does compare pixels and not the objects or data the picture contains (and it requires images of same size and shape):

A very simple and fast approach to do this without openCV and any library for computer vision is to norm the picture arrays by

import numpy as np
picture1 = np.random.rand(100,100)
picture2 = np.random.rand(100,100)
picture1_norm = picture1/np.sqrt(np.sum(picture1**2))
picture2_norm = picture2/np.sqrt(np.sum(picture2**2))

After defining both normed pictures (or matrices) you can just sum over the multiplication of the pictures you like to compare:

1) If you compare similar pictures the sum will return 1:

In[1]: np.sum(picture1_norm**2)
Out[1]: 1.0

2) If they aren't similar, you'll get a value between 0 and 1 (a percentage if you multiply by 100):

In[2]: np.sum(picture2_norm*picture1_norm)
Out[2]: 0.75389941124629822

Please notice that if you have colored pictures you have to do this in all 3 dimensions or just compare a greyscaled version. I often have to compare huge amounts of pictures with arbitrary content and that's a really fast way to do so.

Define it as

<return type> AnalyzeArray(ArrayList<Integer> list) {

I navigated to local.properties, and in there the

ndk.dir=/yo/path/for/NDK

line needs to be updated to where your ndk lies.

I was using Crystax NDK, and didn't realize the original Android NDK was still in use.

What about:

@echo off
set myvar="the list: "
for /r %%i in (*.doc) DO call :concat %%i
echo %myvar%
goto :eof

:concat
set myvar=%myvar% %1;
goto :eof

I had a similar situation where a download needed to stay active overnight and required a key press that refreshed my connection. I also found that the mouse move does not work. However, using notepad and a send key function appears to have done the trick. I send a space instead of a "." because if there is a [yes/no] popup, it will automatically click the default response using the spacebar. Here is the code used.

param($minutes = 120)

$myShell = New-Object -com "Wscript.Shell"

for ($i = 0; $i -lt $minutes; $i++) {
  Start-Sleep -Seconds 30
  $myShell.sendkeys(" ")
}

This function will work for the designated 120 minutes (2 Hours), but can be modified for the timing desired by increasing or decreasing the seconds of the input, or increasing or decreasing the assigned value of the minutes parameter.

Just run the script in powershell ISE, or powershell, and open notepad. A space will be input at the specified interval for the desired length of time ($minutes).

Good Luck!

Additionally Remember, Don't forget to add public keyword like this

[Key] 
int RoleId { get; set; } //wrong method

you must use Public keyword like this

[Key] 
public int RoleId { get; set; } //correct method

Since I cannot add this as a comment, I will leave it here for anyone who finds backticks to be easier to read. Its basically @Reigel answer but with backticks

var numbers = [1, 2, 3, 4, 5];
var option = ``;
for (var i=0;i<numbers.length;i++){
   option += `<option value=${numbers[i]}>${numbers[i]}</option>`;
}
$('#items').append(option);

On Windows, pip lives in C:\[pythondir]\scripts.

So you'll need to add that to your system path in order to run it from the command prompt. You could alternatively cd into that directory each time, but that's a hassle.

See the top answer here for info on how to do that: Adding Python Path on Windows 7

Also, that is a terrifying way to install pip. Grab it from Christophe Gohlke. Grab everything else from there for that matter. http://www.lfd.uci.edu/~gohlke/pythonlibs/

To clarify and update @neo useful answer and the original question. A clean solution consists of installing Pillow, which is an updated version of the Python Imaging Library (PIL). This is done using

pip install pillow

Once Pillow is installed, the standard Matplotlib commands

import matplotlib.pyplot as plt

plt.plot([1, 2])
plt.savefig('image.jpg')

will save the figure into a JPEG file and will not generate a ValueError any more.

Contrary to @amillerrhodes answer, as of Matplotlib 3.1, JPEG files are still not supported. If I remove the Pillow package I still receive a ValueError about an unsupported file type.

Some notes that I also found useful:

• Keep your default values on the right side.

  function whatever($var1, $var2, $var3="constant", $var4="another")
  

• The default value of the argument must be a constant expression. It can't be a variable or a function call.

Recently, I used this .NET Metadata API. I have also written a blog post about it, that shows reading, updating, and removing the EXIF data from images using C#.

using (Metadata metadata = new Metadata("image.jpg"))
{
    IExif root = metadata.GetRootPackage() as IExif;
    if (root != null && root.ExifPackage != null)
    {
        Console.WriteLine(root.ExifPackage.DateTime);
     }
}

This solves the problem on my end.

var files = sftp.ListDirectory(remoteVendorDirectory).Where(f => !f.IsDirectory);

foreach (var file in files)
{
    var filename = $"{LocalDirectory}/{file.Name}";
    if (!File.Exists(filename))
    {
        Console.WriteLine("Downloading  " + file.FullName);
        var localFile = File.OpenWrite(filename);
        sftp.DownloadFile(file.FullName, localFile);
    }
}

You can use HTML5 <figcaption>:

<figure>
  <img src="img.jpg" alt="my img"/>
  <figcaption> Your text </figcaption>
</figure>

Working example.

Everywhere inside the query string, the wildcard should be ? instead of '?'. That should solve the problem.

EDIT :

To add to that, you need to change date '?' to to_date(?, 'yyyy-mm-dd'). Please try that and let me know.

You need to write a document.write object:

document.write('<script type="text/javascript" src="file.js" ></script>');

and place it in your main javascript file

I know this is not directly answering the question at hand but for anyone that comes upon this question who is using WSL running Docker for windows and cmder or conemu.

The trick is not to use Docker which is installed on windows at /mnt/c/Program Files/Docker/Docker/resources/bin/docker.exe but rather to install the ubuntu/linux Docker. It's worth pointing out that you can't run Docker itself from within WSL but you can connect to Docker for windows from the linux Docker client.

Install Docker on Linux

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
sudo apt-get install docker-ce

Connect to Docker for windows on the port 2375 which needs to be enabled from the settings in docker for windows.

docker -H localhost:2375 run -it -v /mnt/c/code:/var/app -w "/var/app" centos:7

Or set the docker_host variable which will allow you to omit the -H switch

export DOCKER_HOST=tcp://localhost:2375

You should now be able to connect interactively with a tty terminal session.

I have used enum FragmentTags to define all my fragment classes.

TAG_FOR_FRAGMENT_A(A.class),
TAG_FOR_FRAGMENT_B(B.class),
TAG_FOR_FRAGMENT_C(C.class)

pass FragmentTags.TAG_FOR_FRAGMENT_A.name() as fragment tag.

and now on

@Override
public void onBackPressed(){
   FragmentManager fragmentManager = getFragmentManager();
   Fragment current
   = fragmentManager.findFragmentById(R.id.fragment_container);
    FragmentTags fragmentTag = FragmentTags.valueOf(current.getTag());

  switch(fragmentTag){
    case TAG_FOR_FRAGMENT_A:
        finish();
        break;
   case TAG_FOR_FRAGMENT_B:
        fragmentManager.popBackStack();
        break;
   case default: 
   break;
}

If /home/smith/Desktop/Test/../ is what you want:

React-PDF is a great resource for this.

It is a bit time consuming converting your markup and CSS to React-PDF's format, but it is easy to understand. Exporting a PDF and from it is fairly straightforward.

To allow a user to download a PDF generated by react-PDF, use their on the fly rendering, which provides a customizable download link. When clicked, the site renders and downloads the PDF for the user.

Here's their REPL which will familiarize you with the markup and styling required. They have a download link for the PDF too, but they don't show the code for that here.

Apart from the DATEDIFF you can also use the TIMEDIFF function or the TIMESTAMPDIFF.

EXAMPLE

SET @date1 = '2010-10-11 12:15:35', @date2 = '2010-10-10 00:00:00';

SELECT 
TIMEDIFF(@date1, @date2) AS 'TIMEDIFF',
TIMESTAMPDIFF(hour, @date1, @date2) AS 'Hours',
TIMESTAMPDIFF(minute, @date1, @date2) AS 'Minutes',
TIMESTAMPDIFF(second, @date1, @date2) AS 'Seconds';

RESULTS

TIMEDIFF : 36:15:35
Hours : -36
Minutes : -2175
Seconds : -130535

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:

$('a#check_var').click(function() {
  alert($("input:radio[name='r']:checked").val()+ ' '+
        $("input:radio[name='s']:checked").val());
});?

You can see the working version here.

The mysql command by default uses UNIX sockets to connect to MySQL.

If you're using MariaDB, you need to load the Unix Socket Authentication Plugin on the server side.

You can do it by editing the [mysqld] configuration like this:

[mysqld]
plugin-load-add = auth_socket.so

Depending on distribution, the config file is usually located at /etc/mysql/ or /usr/local/etc/mysql/

Are you just trying to derive from Area<int>? In which case you do this:

class Rectangle : public Area<int>
{
    // ...
};

EDIT: Following the clarification, it seems you're actually trying to make Rectangle a template as well, in which case the following should work:

template <typename T>
class Rectangle : public Area<T>
{
    // ...
};

Since ?99 the matching between format specifiers and floating-point argument types in C is consistent between printf and scanf. It is

• %f for float
• %lf for double
• %Lf for long double

It just so happens that when arguments of type float are passed as variadic parameters, such arguments are implicitly converted to type double. This is the reason why in printf format specifiers %f and %lf are equivalent and interchangeable. In printf you can "cross-use" %lf with float or %f with double.

But there's no reason to actually do it in practice. Don't use %f to printf arguments of type double. It is a widespread habit born back in C89/90 times, but it is a bad habit. Use %lf in printf for double and keep %f reserved for float arguments.

If you have a built-in command of GridView like insert, update or delete, on row command you can use the following code to get the index:

int index = Convert.ToInt32(e.CommandArgument);

In a custom command, you can set the command argument to yourRow.RowIndex.ToString() and then get it back in the RowCommand event handler. Unless, of course, you need the command argument for another purpose.

With the YouTube video updated as of June 2020 it's very straight forward

1. select on the 3 dots next to like/dislike buttons to open further menu options
2. select "add translations"
3. select language
4. click autogenerate if needed
5. click Actions > Download

You will get and .sbv file

You can use TelephonyManager to do that .

You can skip the container or background image with pure css arrow:

select {

  /* make arrow and background */

  background:
    linear-gradient(45deg, transparent 50%, blue 50%),
    linear-gradient(135deg, blue 50%, transparent 50%),
    linear-gradient(to right, skyblue, skyblue);
  background-position:
    calc(100% - 21px) calc(1em + 2px),
    calc(100% - 16px) calc(1em + 2px),
    100% 0;
  background-size:
    5px 5px,
    5px 5px,
    2.5em 2.5em;
  background-repeat: no-repeat;

  /* styling and reset */

  border: thin solid blue;
  font: 300 1em/100% "Helvetica Neue", Arial, sans-serif;
  line-height: 1.5em;
  padding: 0.5em 3.5em 0.5em 1em;

  /* reset */

  border-radius: 0;
  margin: 0;      
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  -webkit-appearance:none;
  -moz-appearance:none;
}

If you wanna use Javascript then you can use getElementsByName() method to select the input fields and to change the placeholder for each one... see the below code...

document.getElementsByName('Email')[0].placeholder='new text for email';
document.getElementsByName('First Name')[0].placeholder='new text for fname';
document.getElementsByName('Last Name')[0].placeholder='new text for lname';

Otherwise use jQuery:

$('input:text').attr('placeholder','Some New Text');

In short, no. You cannot autowire or manually wire static fields in Spring. You'll have to write your own logic to do this.

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

2020 Update

It is weird that no one has suggested the OOP way:

$date = new \DateTime(); //now
$date->add(new \DateInterval('PT3600S'));//add 3600s / 1 hour

OR

$date = new \DateTime(); //now
$date->add(new \DateInterval('PT60M'));//add 60 min / 1 hour

OR

$date = new \DateTime(); //now
$date->add(new \DateInterval('PT1H'));//add 1 hour

Extract it in string with format:

var_dump($date->format('Y-m-d H:i:s'));

I hope it helps

In order to match the vector lenght and angle with the x,y coordinates of the plot, you can use to following options to plt.quiver:

plt.figure(figsize=(5,2), dpi=100)
plt.quiver(0,0,250,100, angles='xy', scale_units='xy', scale=1)
plt.xlim(0,250)
plt.ylim(0,100)

When using Set-Content instead of Out-File, you can specify the encoding Byte, which can be used to write a byte array to a file. This in combination with a custom UTF8 encoding which does not emit the BOM gives the desired result:

# This variable can be reused
$utf8 = New-Object System.Text.UTF8Encoding $false

$MyFile = Get-Content $MyPath -Raw
Set-Content -Value $utf8.GetBytes($MyFile) -Encoding Byte -Path $MyPath

The difference to using [IO.File]::WriteAllLines() or similar is that it should work fine with any type of item and path, not only actual file paths.

I agree with Palle that using dispatch_after is a good choice here. But you probably don't like the GCD calls as they are quite annoying to write. Instead you can add this handy helper:

public func delay(bySeconds seconds: Double, dispatchLevel: DispatchLevel = .main, closure: @escaping () -> Void) {
    let dispatchTime = DispatchTime.now() + seconds
    dispatchLevel.dispatchQueue.asyncAfter(deadline: dispatchTime, execute: closure)
}

public enum DispatchLevel {
    case main, userInteractive, userInitiated, utility, background
    var dispatchQueue: DispatchQueue {
        switch self {
        case .main:                 return DispatchQueue.main
        case .userInteractive:      return DispatchQueue.global(qos: .userInteractive)
        case .userInitiated:        return DispatchQueue.global(qos: .userInitiated)
        case .utility:              return DispatchQueue.global(qos: .utility)
        case .background:           return DispatchQueue.global(qos: .background)
        }
    }
}

Now you simply delay your code on a background thread like this:

delay(bySeconds: 1.5, dispatchLevel: .background) { 
    // delayed code that will run on background thread
}

Delaying code on the main thread is even simpler:

delay(bySeconds: 1.5) { 
    // delayed code, by default run in main thread
}

If you prefer a Framework that also has some more handy features then checkout HandySwift. You can add it to your project via SwiftPM then use it exactly like in the examples above:

import HandySwift    

delay(by: .seconds(1.5)) { 
    // delayed code
}

Here is how I do it with jQuery

j(".textBoxClass").keypress(function(e)
{
    // if the key pressed is the enter key
    if (e.which == 13)
    {
        // do work
    }
});

Other javascript wouldnt be too different. the catch is checking for keypress argument of "13", which is the enter key

Expanding on @BaiJiFeiLong's answer, add an active={} property to the link:

<Nav.Link as={Link} to="/user" active={pathname.startsWith('/user')}>User</Nav.Link>

This will show the User link as active when any path starts with '/user'. For this to update with each path change, include withRouter() on the component:

import React from 'react'
import { Link, withRouter } from 'react-router-dom'
import Navbar from 'react-bootstrap/Navbar'
import Nav from 'react-bootstrap/Nav'

function Header(props) {
    const pathname = props.location.pathname

    return (
        <Navbar variant="dark" expand="sm" bg="black">
            <Navbar.Brand as={Link} to="/">
                Brand name
            </Navbar.Brand>
            <Navbar.Toggle aria-controls="basic-navbar-nav" />
            <Navbar.Collapse id="basic-navbar-nav">
                <Nav className="mr-auto">
                    <Nav.Link as={Link} to="/user" active={pathname.startsWith('/user')}>User</Nav.Link>
                    <Nav.Link as={Link} to="/about" active={pathname.startsWith('/about')}>About</Nav.Link>
                </Nav>
            </Navbar.Collapse>
        </Navbar>
    )
}

export default withRouter(Header)   // updates on every new page

I put this forward to help anyone needing something readily practical for giving you a nice, prettified (indented) picture of a JS Node. None of the other solutions worked for me for a Node ("cyclical error" or whatever...). This walks you through the tree under the DOM Node (without using recursion) and gives you the depth, tagName (if applicable) and textContent (if applicable).

Any other details from the nodes you encounter as you walk the tree under the head node can be added as per your interest...

function printRNode( node ){
    // make sort of human-readable picture of the node... a bit like PHP print_r

    if( node === undefined || node === null ){
        throwError( 'node was ' + typeof node );
    }
    let s = '';

    // NB walkDOM could be made into a utility function which you could 
    // call with one or more callback functions as parameters...

    function walkDOM( headNode ){
      const stack = [ headNode ];
      const depthCountDowns = [ 1 ];
      while (stack.length > 0) {
        const node = stack.pop();
        const depth = depthCountDowns.length - 1;
        // TODO non-text, non-BR nodes could show more details (attributes, properties, etc.)
        const stringRep = node.nodeType === 3? 'TEXT: |' + node.nodeValue + '|' : 'tag: ' + node.tagName;
        s += '  '.repeat( depth ) + stringRep + '\n';
        const lastIndex = depthCountDowns.length - 1;
        depthCountDowns[ lastIndex ] = depthCountDowns[ lastIndex ] - 1;
        if( node.childNodes.length ){
            depthCountDowns.push( node.childNodes.length );
            stack.push( ... Array.from( node.childNodes ).reverse() );
        }
        while( depthCountDowns[ depthCountDowns.length - 1 ] === 0 ){
            depthCountDowns.splice( -1 );
        }
      }
    } 
    walkDOM( node );
    return s;
}

There is no easy way to remove the "outdated" stuff from an existing workspace. Using the "clean" parameter will not really help, as many of the files you refer to are "free form data", only known to the plugins that are no longer available.

Your best bet is to optimize the re-import, where I would like to point out the following:

• When creating a new workspace, you can already choose to have some settings being copied from the current to the new workspace.
• You can export the preferences of the current workspace (using the Export menu) and re-import them in the new workspace.
• There are lots of recommendations on the Internet to just copy the ${old_workspace}/.metadata/.plugins/org.eclipse.core.runtime/.settings folder from the old to the new workspace. This is surely the fastest way, but it may lead to weird behaviour, because some of your plugins may depend on these settings and on some of the mentioned "free form data" stored elsewhere. (There are even people symlinking these folders over multiple workspaces, but this really requires to use the same plugins on all workspaces.)
• You may want to consider using more project specific settings than workspace preferences in the future. So for instance all the Java compiler settings can either be set on the workspace level or on the project level. If set on the project level, you can put them under version control and are independent of the workspace.

Instead of using count(*) you can SELECT * and you will return all of the details that you want including data_type:

SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_name = 'Address'

MSDN Docs on INFORMATION_SCHEMA.COLUMNS

As far as I understand it correctly, I think it's easiest to work with 4 lists: - Your sourceList - Your destinationList - A removedItemsList - A newlyAddedItemsList

According to the React Documentation it's perfectly OK to call setState() from within the componentDidMount() function.

It will cause render() to be called twice, which is less efficient than only calling it once, but other than that it's perfectly fine.

You can find the documentation here:

https://reactjs.org/docs/react-component.html#componentdidmount

Here is the excerpt from the documentation:

You may call setState() immediately in componentDidMount(). It will trigger an extra rendering, but it will happen before the browser updates the screen. This guarantees that even though the render() will be called twice in this case, the user won’t see the intermediate state. Use this pattern with caution because it often causes performance issues...

var formData = new FormData($("#YOUR_FORM_ID")[0]);
$.ajax({
    url: "upload.php",
    type: "POST",
    data : formData,
    processData: false,
    contentType: false,
    beforeSend: function() {

    },
    success: function(data){




    },
    error: function(xhr, ajaxOptions, thrownError) {
       console.log(thrownError + "\r\n" + xhr.statusText + "\r\n" + xhr.responseText);
    }
});

In file - \vendor\autoload.php, define your gobals variable as follows, should be in the topmost line.

$global_variable = "Some value";//the global variable

Access that global variable anywhere as :-

$GLOBALS['global_variable'];

Enjoy :)

string time = "19851231";
DateTime theTime= DateTime.ParseExact(time,
                                        "yyyyMMdd",
                                        CultureInfo.InvariantCulture,
                                        DateTimeStyles.None);

You got a ninja ')'.

Try :

<div *ngIf="currentStatus !== 'open' || currentStatus !== 'reopen'">

If you want cryptographically secure random numbers, and the exact charset is flexible (say, base64 is fine), you can calculate exactly what the length of random characters you need from the desired output size.

Base 64 text is 1/3 longer than base 256. (2^8 vs 2^6; 8bits/6bits = 1.333 ratio)

import (
    "crypto/rand"
    "encoding/base64"
    "math"
)

func randomBase64String(l int) string {
    buff := make([]byte, int(math.Round(float64(l)/float64(1.33333333333))))
    rand.Read(buff)
    str := base64.RawURLEncoding.EncodeToString(buff)
    return str[:l] // strip 1 extra character we get from odd length results
}

Note: you can also use RawStdEncoding if you prefer + and / characters to - and _

If you want hex, base 16 is 2x longer than base 256. (2^8 vs 2^4; 8bits/4bits = 2x ratio)

import (
    "crypto/rand"
    "encoding/hex"
    "math"
)


func randomBase16String(l int) string {
    buff := make([]byte, int(math.Round(float64(l)/2)))
    rand.Read(buff)
    str := hex.EncodeToString(buff)
    return str[:l] // strip 1 extra character we get from odd length results
}

However, you could extend this to any arbitrary character set if you have a base256 to baseN encoder for your character set. You can do the same size calculation with how many bits are needed to represent your character set. The ratio calculation for any arbitrary charset is: ratio = 8 / log2(len(charset))).

Though both of these solutions are secure, simple, should be fast, and don't waste your crypto entropy pool.

Here's the playground showing it works for any size. https://play.golang.org/p/i61WUVR8_3Z

There is now (Chrome 76+ & FF 69+) a Blob.prototype.arrayBuffer() method which will return a Promise resolving with an ArrayBuffer representing the Blob's data.

(async () => {_x000D_
  const blob = new Blob(['hello']);_x000D_
  const buf = await blob.arrayBuffer();_x000D_
  console.log( buf.byteLength ); // 5_x000D_
})();

Loop over the file to read lines:

with open('somefile') as openfileobject:
    for line in openfileobject:
        do_something()

File objects are iterable and yield lines until EOF. Using the file object as an iterable uses a buffer to ensure performant reads.

You can do the same with the stdin (no need to use raw_input():

import sys

for line in sys.stdin:
    do_something()

To complete the picture, binary reads can be done with:

from functools import partial

with open('somefile', 'rb') as openfileobject:
    for chunk in iter(partial(openfileobject.read, 1024), b''):
        do_something()

where chunk will contain up to 1024 bytes at a time from the file, and iteration stops when openfileobject.read(1024) starts returning empty byte strings.

There's no way to find the maximum / minimum in the general case without looping through all the n elements (if you go from, 1 to n-1, how do you know whether the element n isn't larger (or smaller) than the current max/min)?

You mentioned that the values change every couple of seconds. If you know exactly which values change, you can start with your previous max/min values, and only compare with the new ones, but even in this case, if one of the values which were modified was your old max/min, you may need to loop through them again.

Another alternative - again, only if the number of values which change are small - would be to store the values in a structure such as a tree or a heap, and as the new values arrive you'd insert (or update) them appropriately. But whether you can do that is not clear based on your question.

If you want to get the maximum / minimum element of a given list while looping through all elements, then you can use something like the snippet below, but you will not be able to do that without going through all of them

var list = { "a":4, "b":0.5 , "c":0.35, "d":5 };
var keys = Object.keys(list);
var min = list[keys[0]]; // ignoring case of empty list for conciseness
var max = list[keys[0]];
var i;

for (i = 1; i < keys.length; i++) {
    var value = list[keys[i]];
    if (value < min) min = value;
    if (value > max) max = value;
}

#/bin/bash   
TESTSTR="abc,def,ghij"

for i in $(echo $TESTSTR | tr ',' '\n')
do
echo $i
done

I prefer to use tr instead of sed, becouse sed have problems with special chars like \r \n in some cases.

other solution is to set IFS to certain separator

Here is an extension method for setting unique indexes more fluently:

public static class MappingExtensions
{
    public static PrimitivePropertyConfiguration IsUnique(this PrimitivePropertyConfiguration configuration)
    {
        return configuration.HasColumnAnnotation("Index", new IndexAnnotation(new IndexAttribute { IsUnique = true }));
    }
}

Usage:

modelBuilder 
    .Entity<Person>() 
    .Property(t => t.Name)
    .IsUnique();

Will generate migration such as:

public partial class Add_unique_index : DbMigration
{
    public override void Up()
    {
        CreateIndex("dbo.Person", "Name", unique: true);
    }

    public override void Down()
    {
        DropIndex("dbo.Person", new[] { "Name" });
    }
}

Src: Creating Unique Index with Entity Framework 6.1 fluent API

Just after your Page_Load add this:

public override void VerifyRenderingInServerForm(Control control)
{
    //base.VerifyRenderingInServerForm(control);
}

Note that I don't do anything in the function.

    trie = trie_recursion(trie, deque(word))

pprint.pprint(trie)

Output:

The problem is that jQuery doesn't trigger the native click event for <a> elements so that navigation doesn't happen (the normal behavior of an <a>), so you need to do that manually. For almost all other scenarios, the native DOM event is triggered (at least attempted to - it's in a try/catch).

To trigger it manually, try:

var a = $("<a>")
    .attr("href", "http://i.stack.imgur.com/L8rHf.png")
    .attr("download", "img.png")
    .appendTo("body");

a[0].click();

a.remove();

Relevant line in current jQuery source: https://github.com/jquery/jquery/blob/1.11.1/src/event.js#L332

if ( (!special._default || special._default.apply( eventPath.pop(), data ) === false) &&
        jQuery.acceptData( elem ) ) {

One possible explanation is a database trigger that fires for each DROP TABLE statement. To find the trigger, query the _TRIGGERS dictionary views:

select * from all_triggers
where trigger_type in ('AFTER EVENT', 'BEFORE EVENT')

disable any suspicious trigger with

   alter trigger <trigger_name> disable;

and try re-running your DROP TABLE statement

You can use dir() in a list comprehension to get the attribute names:

names = [p for p in dir(myobj) if not p.startswith('_')]

Use getattr() to get the attributes themselves:

attrs = [getattr(myobj, p) for p in dir(myobj) if not p.startswith('_')]

See this - recreating the symlink may be all you need to do: http://planet-geek.com/archives/2009/09/osx-snow-leopar.html

Remember that your img is not really a DOM element but a javascript expression.

1. This is a JSX attribute expression. Put curly braces around the src string expression and it will work. See http://facebook.github.io/react/docs/jsx-in-depth.html#attribute-expressions

2. In javascript, the class attribute is reference using className. See the note in this section: http://facebook.github.io/react/docs/jsx-in-depth.html#react-composite-components

   /** @jsx React.DOM */
   
   var Hello = React.createClass({
       render: function() {
           return <div><img src={'http://placehold.it/400x20&text=slide1'} alt="boohoo" className="img-responsive"/><span>Hello {this.props.name}</span></div>;
       }
   });
   
   React.renderComponent(<Hello name="World" />, document.body);
   

Try using the STR() function.

SELECT STR(float_field, 25, 5)

STR() Function

Another note: this pads on the left with spaces. If this is a problem combine with LTRIM:

SELECT LTRIM(STR(float_field, 25, 5))

Basically you need following things to make location detector android app

• Location Listener, which detect current location
• Marker to add and animate when person moves
• Polyline to add path on person's movement
• Services for sending and receiving location
• Rest API / Firebase Realtime Database to store and fetch locations

Now if you write each of these module yourself then it needs much time and efforts. So it would be better to use ready resources that are being maintained already.

Using all these resources, you will be able to create an flawless android location detection app.

1. Location Listening

You will first need to listen for current location of user. You can use any of below libraries to quick start.

Google Play Location Samples

This library provide last known location, location updates

Location Manager

With this library you just need to provide a Configuration object with your requirements, and you will receive a location or a fail reason with all the stuff are described above handled.

Live Location Sharing

Use this open source repo of the Hypertrack Live app to build live location sharing experience within your app within a few hours. HyperTrack Live app helps you share your Live Location with friends and family through your favorite messaging app when you are on the way to meet up. HyperTrack Live uses HyperTrack APIs and SDKs.

2. Markers Library

Google Maps Android API utility library

• Marker clustering — handles the display of a large number of points
• Heat maps — display a large number of points as a heat map
• IconGenerator — display text on your Markers
• Poly decoding and encoding — compact encoding for paths, interoperability with Maps API web services
• Spherical geometry — for example: computeDistance, computeHeading, computeArea
• KML — displays KML data
• GeoJSON — displays and styles GeoJSON data

3. Polyline Libraries

DrawRouteMaps

If you want to add route maps feature in your apps you can use DrawRouteMaps to make you work more easier. This is lib will help you to draw route maps between two point LatLng.

trail-android

Simple, smooth animation for route / polylines on google maps using projections. (WIP)

Google-Directions-Android

This project allows you to calculate the direction between two locations and display the route on a Google Map using the Google Directions API.

A map demo app for quick start with maps

create-react-app and react-scripts

react-scripts is a set of scripts from the create-react-app starter pack. create-react-app helps you kick off projects without configuring, so you do not have to setup your project by yourself.

react-scripts start sets up the development environment and starts a server, as well as hot module reloading. You can read here to see what everything it does for you.

with create-react-app you have following features out of the box.

• React, JSX, ES6, and Flow syntax support.
• Language extras beyond ES6 like the object spread operator.
• Autoprefixed CSS, so you don’t need -webkit- or other prefixes.
• A fast interactive unit test runner with built-in support for coverage reporting.
• A live development server that warns about common mistakes.
• A build script to bundle JS, CSS, and images for production, with hashes and sourcemaps.
• An offline-first service worker and a web app manifest, meeting all the Progressive Web App criteria.
• Hassle-free updates for the above tools with a single dependency.

npm scripts

npm start is a shortcut for npm run start.

npm run is used to run scripts that you define in the scripts object of your package.json

if there is no start key in the scripts object, it will default to node server.js

Sometimes you want to do more than the react scripts gives you, in this case you can do react-scripts eject. This will transform your project from a "managed" state into a not managed state, where you have full control over dependencies, build scripts and other configurations.

Don't use getters setters unless needed for your current delivery I.e. Don't think too much about what would happen in the future, if any thing to be changed its a change request in most of the production applications, systems.

Think simple, easy, add complexity when needed.

I would not take advantage of ignorance of business owners of deep technical know how just because I think it's correct or I like the approach.

I have massive system written without getters setters only with access modifiers and some methods to validate n perform biz logic. If you absolutely needed the. Use anything.

That is how you define an anonymous function that gets called when the document is ready.

Adding to the accepted answer by Luke West. If you have any entitlements:

1. Close Xcode
2. Change the entitlements filename
3. Go into Xcode, select the entitlements file should be highlighted red, in the File inspector select the Folder icon and select your renamed file.
4. Go into Build Settings, and search "entitlements" and update the folder name and file name for the entitlement.
5. Clean and rebuild

Also you can use DownloadFileAsync method in WebClient class. It downloads to a local file the resource with the specified URI. Also this method does not block the calling thread.

Sample:

    webClient.DownloadFileAsync(new Uri("http://www.example.com/file/test.jpg"), "test.jpg");

For more information:

We can use package Guzzle in Laravel, it is a PHP HTTP client to send HTTP requests.

You can install Guzzle through composer

composer require guzzlehttp/guzzle:~6.0

Or you can specify Guzzle as a dependency in your project's existing composer.json

{
   "require": {
      "guzzlehttp/guzzle": "~6.0"
   }
}

Example code in laravel 5 using Guzzle as shown below,

use GuzzleHttp\Client;
class yourController extends Controller {

    public function saveApiData()
    {
        $client = new Client();
        $res = $client->request('POST', 'https://url_to_the_api', [
            'form_params' => [
                'client_id' => 'test_id',
                'secret' => 'test_secret',
            ]
        ]);
        echo $res->getStatusCode();
        // 200
        echo $res->getHeader('content-type');
        // 'application/json; charset=utf8'
        echo $res->getBody();
        // {"type":"User"...'
}

Are you looking for behavior similar to the x that shows up on the right side of text fields on an iphone that clears the text when tapped? It's called clearButtonMode there. Here is how to create that same functionality in an Android EditText view:

String value = "";//any text you are pre-filling in the EditText

final EditText et = new EditText(this);
et.setText(value);
final Drawable x = getResources().getDrawable(R.drawable.presence_offline);//your x image, this one from standard android images looks pretty good actually
x.setBounds(0, 0, x.getIntrinsicWidth(), x.getIntrinsicHeight());
et.setCompoundDrawables(null, null, value.equals("") ? null : x, null);
et.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (et.getCompoundDrawables()[2] == null) {
            return false;
        }
        if (event.getAction() != MotionEvent.ACTION_UP) {
            return false;
        }
        if (event.getX() > et.getWidth() - et.getPaddingRight() - x.getIntrinsicWidth()) {
            et.setText("");
            et.setCompoundDrawables(null, null, null, null);
        }
        return false;
    }
});
et.addTextChangedListener(new TextWatcher() {
    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        et.setCompoundDrawables(null, null, et.getText().toString().equals("") ? null : x, null);
    }

    @Override
    public void afterTextChanged(Editable arg0) {
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }
});

Not an actual answer but more as a reference.

If you are using the jaxws Maven plugin and you get the same error message, add the mentioned property to the plugin configuration:

...
<plugin>
  <groupId>org.jvnet.jax-ws-commons</groupId>
  <artifactId>jaxws-maven-plugin</artifactId>
  <version>2.3</version>
  <configuration>
    <!-- Needed with JAXP 1.5 -->
    <vmArgs>
        <vmArg>-Djavax.xml.accessExternalSchema=all</vmArg>
    </vmArgs>
  </configuration>
</plugin>

Ljava.lang.String;@ is returned where you used string arrays as strings. Employee.getSelectCancel() does not seem to return a String[]

You may use pip for that without using the network. See in the docs (search for "Install a particular source archive file"). Any of those should work:

pip install relative_path_to_seaborn.tar.gz    
pip install absolute_path_to_seaborn.tar.gz    
pip install file:///absolute_path_to_seaborn.tar.gz    

Or you may uncompress the archive and use setup.py directly with either pip or python:

cd directory_containing_tar.gz
tar -xvzf seaborn-0.10.1.tar.gz
pip install seaborn-0.10.1
python setup.py install

Of course, you should also download required packages and install them the same way before you proceed.

set the variable on window:

window.a_href = a_href;

C or C++ will not check the bounds of an array access.

You are allocating the array on the stack. Indexing the array via array[3] is equivalent to *(array + 3), where array is a pointer to &array[0]. This will result in undefined behavior.

One way to catch this sometimes in C is to use a static checker, such as splint. If you run:

splint +bounds array.c

on,

int main(void)
{
    int array[1];

    array[1] = 1;

    return 0;
}

then you will get the warning:

array.c: (in function main) array.c:5:9: Likely out-of-bounds store: array[1] Unable to resolve constraint: requires 0 >= 1 needed to satisfy precondition: requires maxSet(array @ array.c:5:9) >= 1 A memory write may write to an address beyond the allocated buffer.

For the modification, you could use tag.text from xml. Here is snippet:

import xml.etree.ElementTree as ET

tree = ET.parse('country_data.xml')
root = tree.getroot()

for rank in root.iter('rank'):
    new_rank = int(rank.text) + 1
    rank.text = str(new_rank)
    
tree.write('output.xml')

The rank in the code is example of tag, which depending on your XML file contents.

This is how I do it if I need a form displayed for each item, and inputs for various properties. Really depends on what I'm trying to do though.

ViewModel looks like this:

public class MyViewModel
{
   public List<Person> Persons{get;set;}
}

View(with BeginForm of course):

@model MyViewModel


@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    @Html.HiddenFor(m => m.Persons[i].PersonId)
    @Html.EditorFor(m => m.Persons[i].FirstName) 
    @Html.EditorFor(m => m.Persons[i].LastName)         
}

Action:

[HttpPost]public ViewResult(MyViewModel vm)
{
...

Note that on post back only properties which had inputs available will have values. I.e., if Person had a .SSN property, it would not be available in the post action because it wasn't a field in the form.

Note that the way MVC's model binding works, it will only look for consecutive ID's. So doing something like this where you conditionally hide an item will cause it to not bind any data after the 5th item, because once it encounters a gap in the IDs, it will stop binding. Even if there were 10 people, you would only get the first 4 on the postback:

@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    if(i != 4)//conditionally hide 5th item, 
    { //but BUG occurs on postback, all items after 5th will not be bound to the the list
      @Html.HiddenFor(m => m.Persons[i].PersonId)
      @Html.EditorFor(m => m.Persons[i].FirstName) 
      @Html.EditorFor(m => m.Persons[i].LastName)           
    }
}

It's common when you want to implement a singleton. The class can have a static "factory method" that checks if the class has already been instantiated, and calls the constructor if it hasn't.

For enable PHP Extension intl , follow the Steps..

1. Open the xampp/php/php.ini file in any editor.
2. Search ";extension=php_intl.dll"
3. kindly remove the starting semicolon ( ; ) Like : ;extension=php_intl.dll. to. extension=php_intl.dll.
4. Save the xampp/php/php.ini file.
5. Restart your xampp/wamp.

You are creating an alias P and later in the where clause you are using the same, that is what is creating the problem. Don't use P in where, try this instead:

SELECT Replace(Postcode, ' ', '') AS P FROM Contacts
WHERE Postcode LIKE 'NW101%'

window.navigate is NOT supported in some browsers, so that one should be avoided. Any of the other methods using the location property are the most reliable and consistent approach

The REFERER is sent by the client's browser as part of the HTTP protocol, and is therefore unreliable indeed. It might not be there, it might be forged, you just can't trust it if it's for security reasons.

If you want to verify if a request is coming from your site, well you can't, but you can verify the user has been to your site and/or is authenticated. Cookies are sent in AJAX requests so you can rely on that.

Setting android:clipToPadding="false" in the top relative layout has solved the problem.

Why not make use of a tooltip?

private void ShowToolTip(object sender, string message)
{
  new ToolTip().Show(message, this, Cursor.Position.X - this.Location.X, Cursor.Position.Y - this.Location.Y, 1000);
}

The code above will show message for 1000 milliseconds (1 second) where you clicked.

To call it, you can use the following in your button click event:

ShowToolTip("Hello World");

LINUX

struct timeval tv;
tv.tv_sec = 30;        // 30 Secs Timeout
tv.tv_usec = 0;        // Not init'ing this can cause strange errors
setsockopt(sockfd, SOL_SOCKET, SO_RCVTIMEO, (const char*)&tv,sizeof(struct timeval));

WINDOWS

DWORD timeout = SOCKET_READ_TIMEOUT_SEC * 1000;
setsockopt(socket, SOL_SOCKET, SO_RCVTIMEO, (const char*)&timeout, sizeof(timeout));

NOTE: You have put this setting before bind() function call for proper run

Just a little more clarification: A property without 'get','set' won't be able to be bound

I'm facing the case just like the asker's case. And I must have the following things in order for the bind to work properly:

//(1) Declare a property with 'get','set' in code behind
public partial class my_class:Window {
  public String My_Property { get; set; }
  ...

//(2) Initialise the property in constructor of code behind
public partial class my_class:Window {
  ...
  public my_class() {
     My_Property = "my-string-value";
     InitializeComponent();
  }

//(3) Set data context in window xaml and specify a binding
<Window ...
DataContext="{Binding RelativeSource={RelativeSource Self}}">
  <TextBlock Text="{Binding My_Property}"/>
</Window>

You can use SELECT as lambacck said or add parentheses:

SET @times = (SELECT COUNT(DidWin)as "I Win"
FROM thetable
WHERE DidWin = 1 AND Playername='Me');

What all should I know about web.xml apart from element name and their usage ?

The SINGLE most important JSP configuration parameter of ALL TIME is in your web.xml. Ladies and gentlemen, I give you... the TRIM-DIRECTIVE-WHITESPACES option!

<jsp-config>
    <jsp-property-group>
        <url-pattern>*.jsp</url-pattern>
        <trim-directive-whitespaces>true</trim-directive-whitespaces>
    </jsp-property-group>
</jsp-config>

This removes all the hundreds or thousands of lines of white space that you'll get in your generated HTML if you use any tag libraries (loops are particularly ugly & wasteful).

The other big one is the default web page (the page you get automatically sent to when you don't enter a web page in the URL):

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>    

Just get the source, and compile Boost yourself; it has become very easy. Here is an example for the current version of Boost on the current macOS as of this writing:

1. Download the the .tar.gz from https://www.boost.org/users/download/#live

2. Unpack and go into the directory:

   tar -xzf boost_1_50_0.tar.gz
   cd boost_1_50_0

3. Configure (and build bjam):

   ./bootstrap.sh --prefix=/some/dir/you/would/like/to/prefix

4. Build:

   ./b2

5. Install:

   ./b2 install

Depending on the prefix you choose in Step 3, you might need to sudo Step 5, if the script tries copy files to a protected location.

You don't have to give version numbers. Just run:

sudo apt-get install php-curl

It worked for me. Don't forgot to restart the server:

sudo service apache2 restart

Change

@RequestMapping(value = "/test", method = RequestMethod.POST)

To

@RequestMapping(value = "/test", method = RequestMethod.GET)

You can use window.open for this

window.open("page url",null,
"height=200,width=400,status=yes,toolbar=no,menubar=no,location=no");

have a look at this link.. window.open

Since GNU parallel was not mentioned yet, let me give another way:

cat url.list | parallel -j 8 wget -O {#}.html {}

This question has been hanging around for a while, but none of the fixes I could find worked for me (having the same issue with ipad), but I managed my own solution which should work for most people I imagine.

Here's my code:

html {
   background: url("../images/blahblah.jpg") repeat-y;
   min-width: 100%;
   background-size: contain;
}

Enjoy!

• .length is a field, containing the capacity (NOT the number of elements the array contains at the moment) of arrays.

• length() is a method used by Strings (amongst others), it returns the number of chars in the String; with Strings, capacity and number of containing elements (chars) have the same value.

• size() is a method implemented by all members of Collection (lists, sets, stacks,...). It returns the number of elements (NOT the capacity; some collections even don´t have a defined capacity) the collection contains.

2 ways that I know of :

USING PPM :

With Windows (ActivePerl) I've used ppm

from the command line type ppm. At the ppm prompt ...

ppm> install foo

or

ppm> search foo

to get a list of foo modules available. Type help for all the commands

USING CPAN :

you can also use CPAN like this (*nix systems) :

perl -MCPAN -e 'shell'

gets you a prompt

cpan>

at the prompt ...

cpan> install foo  (again to install the foo module)

type h to get a list of commands for cpan

Look carefully at your output:

5wlfgALGbXOahekxSs9wlfgALGbXOahekxSs5
^                 ^                 ^

I've highlighted the "5", "9", "5" of your original string. The Python join() method is a string method, and takes a list of things to join with the string. A simpler example might help explain:

>>> ",".join(["a", "b", "c"])
'a,b,c'

The "," is inserted between each element of the given list. In your case, your "list" is the string representation "595", which is treated as the list ["5", "9", "5"].

It appears that you're looking for + instead:

print array.array('c', random.sample(string.ascii_letters, 20 - len(strid)))
.tostring() + strid

You cannot just put in a function to pause Javascript unfortunately.

You have to use setTimeout()

Example:

function startTimer () {
    timer.start();
    setTimeout(stopTimer,5000);
}

function stopTimer () {
    timer.stop();
}

EDIT:

For your user generated countdown, it is just as simple.

HTML:

<input type="number" id="delay" min="1" max="5">

JS:

var delayInSeconds = parseInt(delay.value);
var delayInMilliseconds = delayInSeconds*1000;

function startTimer () {
    timer.start();
    setTimeout(stopTimer,delayInMilliseconds);
}

function stopTimer () {
    timer.stop;
}

Now you simply need to add a trigger for startTimer(), such as onchange.

It looks like you're writing PHP, in which case you want:

<?
$arr=array('us'=>'United', 'ca'=>'canada');
$key='ca';
echo $arr[$key];
?>

Notice that the ('us'=>'United', 'ca'=>'canada') needs to be a parameter to the array function in PHP.

Most programming languages that support associative arrays or dictionaries use arr['key'] to retrieve the item specified by 'key'

For instance:

Ruby

ruby-1.9.1-p378 > h = {'us' => 'USA', 'ca' => 'Canada' }
 => {"us"=>"USA", "ca"=>"Canada"} 
ruby-1.9.1-p378 > h['ca']
 => "Canada" 

Python

>>> h = {'us':'USA', 'ca':'Canada'}
>>> h['ca']
'Canada'

C#

class P
{
    static void Main()
    {
        var d = new System.Collections.Generic.Dictionary<string, string> { {"us", "USA"}, {"ca", "Canada"}};
        System.Console.WriteLine(d["ca"]);
    }
}

Lua

t = {us='USA', ca='Canada'}
print(t['ca'])
print(t.ca) -- Lua's a little different with tables

The HttpWebRequest modifies the CookieContainer assigned to it. There is no need to process returned cookies. Simply assign your cookie container to every web request.

public class CookieAwareWebClient : WebClient
{
    public CookieContainer CookieContainer { get; set; } = new CookieContainer();

    protected override WebRequest GetWebRequest(Uri uri)
    {
        WebRequest request = base.GetWebRequest(uri);

        {
            (request as HttpWebRequest).CookieContainer = CookieContainer;
        }
        return request;
    }

            console.log(chartElements[0].label);
        }
    },
},

the chartElements[0] is the clicked section of your chart, no need to use getElementsAtEvent anymore. It works on Chart v2.9.4

I experienced the same issue, same version of Chrome though it's unrelated to the issue. With the developer console I captured an instance of the request that spawned this, and it is an API call served by ad.doubleclick.net. Specifically, this resource returns a response with Content-Disposition: attachment; filename="f.txt".

The URL I happened to capture was https://ad.doubleclick.net/adj/N7412.226578.VEVO/B8463950.115078190;sz=300x60...

Per curl:

$ curl -I 'https://ad.doubleclick.net/adj/N7412.226578.VEVO/B8463950.115078190;sz=300x60;click=https://2975c.v.fwmrm.net/ad/l/1?s=b035&n=10613%3B40185%3B375600%3B383270&t=1424475157058697012&f=&r=40185&adid=9201685&reid=3674011&arid=0&auid=&cn=defaultClick&et=c&_cc=&tpos=&sr=0&cr=;ord=435266097?'

Here is an efficient way to solve this question using For loops in Java

 public static void main(String[] args) {

    int [] numbers = { 1, 2, 3, 4 };
    int size = numbers.length;

    int sum = 0;
    for (int i = 0; i < size; i++) {
        sum += numbers[i];
    }

    System.out.println(sum);
}

Use this code:

driver.manage().window().maximize() 

works well,

Please make sure that you give enough time for the window to load before you declare this statement.

If you are finding any element to input some data then provide reasonable delay between this and the input statement.

The case values are just codeless "goto" points that can share the same entry point:

case text1:
case text4: {
//Do something
break;
}

Note that the braces are redundant.

If you want to do something more complicated with your text you could create your own filter and do some magic before returning the html. With a templatag file looking like this:

from django import template
from django.utils.safestring import mark_safe

register = template.Library()

@register.filter
def do_something(title, content):

    something = '<h1>%s</h1><p>%s</p>' % (title, content)
    return mark_safe(something)

Then you could add this in your template file

<body>
...
    {{ title|do_something:content }}
...
</body>

And this would give you a nice outcome.

tl;dr

LocalDate.parse( "2013-09-18" )

… and …

myLocalDate.toString()  // Example: 2013-09-18

java.time

The Question and other Answers are out-of-date. The troublesome old legacy date-time classes are now supplanted by the java.time classes.

ISO 8601

Your input string happens to comply with standard ISO 8601 format, YYYY-MM-DD. The java.time classes use ISO 8601 formats by default when parsing and generating string representations of date-time values. So no need to specify a formatting pattern.

LocalDate

The LocalDate class represents a date-only value without time-of-day and without time zone.

LocalDate ld = LocalDate.parse( "2013-09-18" );

About java.time

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

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

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

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

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

try this code: :)

get value:

 $("#Ostans option:selected").val() + '.' + $("#shahrha option:selected").val()

get text:

 $("#Ostans option:selected").text() + '.' + $("#shahrha option:selected").text()

I just came up with a general solution, which should work on most websites. I tried this on Chrome only, but this method should work with any other browser, though, as Dev Tools are pretty much the same in them all.

Steps:

1. Open the browser's Dev Tools (usually F12, or Ctrl-Shift-I, or right-click and then Inspect in the popup menu) on the page with the video you are interested in.
2. Go to Network tab and then reload the page. The tab will get populated with a list of requests (may be up to a hundred of them or even more).
3. Search through the names of requests and find the request with .m3u8 extension. There may be many of them, but most likely the first you find is the one you are looking for. It may have any name, e.g. playlist.m3u8.
4. Open the request and under Headers subsection you will see request's full URL in Request URL field. Copy it.
5. Extract the video from m3u8. There are many ways to do it, I'll give you those I tried, but you can google more by "download video from m3u8".
   • Option 1. If you have VLC player installed, feed the URL to VLC using "Open Network Stream..." menu option. I'm not going to go into details on this part here, there are a number of comprehensive guides in many places, for example, here. If the page doesn't work, you can always google another one by "vlc download online video".
   • Option 2. If you are more into command line, use FFMPEG or your own script, as directed in this SuperUser question.

The output in your first printline is using your formatter. The output in your second (the date created from your parsed string) is output using Date#toString which formats according to its own rules. That is, you're not using a formatter.

The rules are as per what you're seeing and described here: http://docs.oracle.com/javase/6/docs/api/java/util/Date.html#toString()

A lot of answers have been given, based on technical considerations, especially around performance. According to me, choice between TreeSet and HashSet matters.

But I would rather say the choice should be driven by conceptual considerations first.

If, for the objects your need to manipulate, a natural ordering does not make sense, then do not use TreeSet.
It is a sorted set, since it implements SortedSet. So it means you need to override function compareTo, which should be consistent with what returns function equals. For example if you have a set of objects of a class called Student, then I do not think a TreeSet would make sense, since there is no natural ordering between students. You can order them by their average grade, okay, but this is not a "natural ordering". Function compareTo would return 0 not only when two objects represent the same student, but also when two different students have the same grade. For the second case, equals would return false (unless you decide to make the latter return true when two different students have the same grade, which would make equals function have a misleading meaning, not to say a wrong meaning.)
Please note this consistency between equals and compareTo is optional, but strongly recommended. Otherwise the contract of interface Set is broken, making your code misleading to other people, thus also possibly leading to unexpected behavior.

This link might be a good source of information regarding this question.

String to yyyy-MM-dd date format: Example:

TxtCalStDate.Text = Convert.ToDateTime(objItem["StartDate"]).ToString("yyyy/MM/dd");   

@amir response in Swift :

// Get language prefered by user
let langageRegion = NSLocale.preferredLanguages().first!
let languageDic = NSLocale.componentsFromLocaleIdentifier(langageRegion)
let language = languageDic[NSLocaleLanguageCode]

To remove you tube controls and title you can do something like this.

<iframe width="560" height="315" src="https://www.youtube.com/embed/zP0Wnb9RI9Q?autoplay=1&showinfo=0&controls=0" frameborder="0" allowfullscreen ></iframe>

check this example how it look

showinfo=0 is used to remove title and &controls=0 is used for remove controls like volume,play,pause,expend.

In addition to previous answers, I recommend to first calculate the ratio in the exponent, then taking the square:

def gaussian(x,x0,sigma):
  return np.exp(-np.power((x - x0)/sigma, 2.)/2.)

That way, you can also calculate the gaussian of very small or very large numbers:

In: gaussian(1e-12,5e-12,3e-12)
Out: 0.64118038842995462

You propably have to write some JavaScript, because there is no way to estimate the height of all the users of the page.

I imagine that there are not many browsers supporting extension. Indeed, I have been interested in this question for the last year and I only found Dolphin supporting add-ons and other cool features announced few days ago. I want to test it soon.

Often you will want to specify a manifest, like so:

jar -cvfm myJar.jar myManifest.txt myApp.class

Which reads: "create verbose jarFilename manifestFilename", followed by the files you want to include. Verbose means print messages about what it's doing.

Note that the name of the manifest file you supply can be anything, as jar will automatically rename it and put it into the right directory within the jar file.

Did you restart the server after you changed the config file?

Can you telnet to the server from a different machine?

Can you telnet to the server from the server itself?

telnet <ip address> 80

telnet localhost 80

you can also make it overflow: auto and give a maximum fixed height and width that way, when the text or whatever is in there, overflows it'll show only the required scrollbar

like so:

BEGIN TRANSACTION; 
UPDATE table_name
  SET column_name=REPLACE(column_name,'text_to_find','replace_with_this'); 
COMMIT TRANSACTION;

Example: Replaces <script... with <a ... to eliminate javascript vulnerabilities

BEGIN TRANSACTION; UPDATE testdb
SET title=REPLACE(title,'script','a'); COMMIT TRANSACTION;

Giving soft keyboard some time to close works for me.

$('#ButtonCancel').click(function () {
    document.body.focus();

    setTimeout(function () {
        //close the dialog, switch to another screen, etc.
    }, 300);
});

Please see this link.

I looked in all my apache log files until I found the actual error (I had changed the <VirtualHost> from _default_ to my fqdn). When I fixed this error, everything worked fine.

Using this and {{this}}. See code below in node.js:

var Handlebars= require("handlebars");
var randomList= ["James Bond", "Dr. No", "Octopussy", "Goldeneye"];
var source= "<ul>{{#each this}}<li>{{this}}</li>{{/each}}</ul>";
var template= Handlebars.compile(source);
console.log(template(randomList));

Console log output:

<ul><li>James Bond</li><li>Dr. No</li><li>Octopussy</li><li>Goldeneye</li></ul>

Put this into your collection view delegate. It considers more of the the basic flow layout settings than the other answers and is thereby more generic.

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section
{
    NSInteger cellCount = [collectionView.dataSource collectionView:collectionView numberOfItemsInSection:section];
    if( cellCount >0 )
    {
        CGFloat cellWidth = ((UICollectionViewFlowLayout*)collectionViewLayout).itemSize.width+((UICollectionViewFlowLayout*)collectionViewLayout).minimumInteritemSpacing;
        CGFloat totalCellWidth = cellWidth*cellCount + spacing*(cellCount-1);
        CGFloat contentWidth = collectionView.frame.size.width-collectionView.contentInset.left-collectionView.contentInset.right;
        if( totalCellWidth<contentWidth )
        {
            CGFloat padding = (contentWidth - totalCellWidth) / 2.0;
            return UIEdgeInsetsMake(0, padding, 0, padding);
        }
    }
    return UIEdgeInsetsZero;
}

swift version (thanks g0ld2k):

extension CommunityConnectViewController: UICollectionViewDelegateFlowLayout {
    func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAtIndex section: Int) -> UIEdgeInsets {

    // Translated from Objective-C version at: http://stackoverflow.com/a/27656363/309736

        let cellCount = CGFloat(viewModel.getNumOfItemsInSection(0))

        if cellCount > 0 {
            let flowLayout = collectionViewLayout as! UICollectionViewFlowLayout
            let cellWidth = flowLayout.itemSize.width + flowLayout.minimumInteritemSpacing
            let totalCellWidth = cellWidth*cellCount + spacing*(cellCount-1)
            let contentWidth = collectionView.frame.size.width - collectionView.contentInset.left - collectionView.contentInset.right

            if (totalCellWidth < contentWidth) {
                let padding = (contentWidth - totalCellWidth) / 2.0
                return UIEdgeInsetsMake(0, padding, 0, padding)
            }
        }

        return UIEdgeInsetsZero
    }
}

Becareful with swig and C++: http://www.swig.org/Doc1.3/SWIG.html#SWIG_nn8

Running SWIG on C++ source files (what would appear in a .C or .cxx file) is not recommended. Even though SWIG can parse C++ class declarations, it ignores declarations that are decoupled from their original class definition (the declarations are parsed, but a lot of warning messages may be generated). For example:

/* Not supported by SWIG */
int foo::bar(int) {
    ... whatever ...
}

It's rarely to have a C++ class limited to only one .h file.

Also, the versions of swig supporting JavaScript is swig-3.0.1 or later.

if it's Oracle you would use the "all_views" table.

It really depends on your dbms.

You can access the inactive tags array with (assuming $myArray contains the array)

$myArray['inactiveTags'];

Your question doesn't seem to go beyond accessing the contents of the inactiveTags key so I can only speculate with what your final goal is.

The first key:value pair in the inactiveTags array is

array ('195' => array(
                 'id' => 195, 
                 'tag' => 'auto')
      )

To access the tag value, you would use

$myArray['inactiveTags'][195]['tag']; // auto

If you want to loop through each inactiveTags element, I would suggest:

foreach($myArray['inactiveTags'] as $value) {
  print $value['id'];
  print $value['tag'];
}

This will print all the id and tag values for each inactiveTag

Just add a readme or a .gitignore and then delete it, not from terminal, from the github website, that will give a empty repository

What is working for me is - history.replaceState() function which is as follows -

history.replaceState(data,"Title of page"[,'url-of-the-page']);

This will not reload page, you can make use of it with event of javascript

Try the following, no extra headers

wget -qO- www.google.com

Note the trailing -. This is part of the normal command argument for -O to cat out to a file, but since we don't use > to direct to a file, it goes out to the shell. You can use -qO- or -qO -.

Something important has been said by Tom:

if you use the has-a concept, you avoid the issue.

Indeed, if instead of using extends and implements you define two attributes, one of type rectangle, one of type JLabel in your Tile class, then you can define a Rectangle to be either an interface or a class.

Furthermore, I would normally encourage the use of interfaces in connection with has-a, but I guess it would be an overkill in your situation. However, you are the only one that can decide on this point (tradeoff flexibility/over-engineering).

I suspect you want to check that it's after 11pm or before 7am:

select *
from MyTable
where CAST(Created as time) >= '23:00:00' 
   or CAST(Created as time) < '07:00:00'

It's looking for an element with id list which has a property value equal to 2.
What you want is the option child of the list:

$("#list option[value='2']").text()

To Access the Camera and take pictures and set ImageView on Android

You have to use Uri file = Uri.fromFile(getOutputMediaFile()); for marshmallow.

Use below link to get path

https://androidkennel.org/android-camera-access-tutorial/

Here is the solution I'm using:

const result = `${ window.location.protocol }//${ window.location.host }`;

EDIT:

To add cross-browser compatibility, use the following:

const result = `${ window.location.protocol }//${ window.location.hostname + (window.location.port ? ':' + window.location.port: '') }`;

Why so complicated? just put this :

data-html='true'

I would suggest you use the below css

.showhideoverlay { 
  width: 100%;
  height: 100%;
  right: 0px;
  top: 0px;
  position: fixed;
  background: #000;
  opacity: 0.75;
}

You can then use a simple toggle function:

$('a.open').click(function() {
  $('div.showhideoverlay').toggle("slow");
});

This will display the overlay menu from right to left. Alternatively, you can use the positioning for changing the effect from top or bottom, i.e. use bottom: 0; instead of top: 0; - you will see menu sliding from right-bottom corner.

Steps to debug:-

In case you face any issue in kubernetes, first step is to check if kubernetes self applications are running fine or not.

Command to check:- kubectl get pods -n kube-system

If you see any pod is crashing, check it's logs

if getting NotReady state error, verify network pod logs.

if not able to resolve with above, follow below steps:-

1. kubectl get nodes # Check which node is not in ready state

2. kubectl describe node nodename #nodename which is not in readystate

3. ssh to that node

4. execute systemctl status kubelet # Make sure kubelet is running

5. systemctl status docker # Make sure docker service is running

6. journalctl -u kubelet # To Check logs in depth

Most probably you will get to know about error here, After fixing it reset kubelet with below commands:-

6. systemctl daemon-reload
7. systemctl restart kubelet

In case you still didn't get the root cause, check below things:-

8. Make sure your node has enough space and memory. Check for /var directory space especially. command to check: -df -kh, free -m

9. Verify cpu utilization with top command. and make sure any process is not taking an unexpected memory.

Python string objects are immutable. Example:

>>> a = 'tanim'
>>> 'Address of a is:{}'.format(id(a))
'Address of a is:64281536'
>>> a = 'ahmed'
>>> 'Address of a is:{}'.format(id(a))
'Address of a is:64281600'

In this example we can see that when we assign different value in a it doesn't modify.A new object is created.
And it can't be modified. Example:

  >>> a[0] = 'c'
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    **TypeError**: 'str' object does not support item assignment

A error occurs.

Tieme put a lot of effort into his excellent answer, but I think the core of the OP's question is how these technologies relate to PHP rather than how each technology works.

PHP is the most used language in web development besides the obvious client side HTML, CSS, and Javascript. Yet PHP has 2 major issues when it comes to real-time applications:

1. PHP started as a very basic CGI. PHP has progressed very far since its early stage, but it happened in small steps. PHP already had many millions of users by the time it became the embed-able and flexible C library that it is today, most of whom were dependent on its earlier model of execution, so it hasn't yet made a solid attempt to escape the CGI model internally. Even the command line interface invokes the PHP library (libphp5.so on Linux, php5ts.dll on Windows, etc) as if it still a CGI processing a GET/POST request. It still executes code as if it just has to build a "page" and then end its life cycle. As a result, it has very little support for multi-thread or event-driven programming (within PHP userspace), making it currently unpractical for real-time, multi-user applications.

Note that PHP does have extensions to provide event loops (such as libevent) and threads (such as pthreads) in PHP userspace, but very, very, few of the applications use these.

2. PHP still has significant issues with garbage collection. Although these issues have been consistently improving (likely its greatest step to end the life cycle as described above), even the best attempts at creating long-running PHP applications require being restarted on a regular basis. This also makes it unpractical for real-time applications.

PHP 7 will be a great step to fix these issues as well, and seems very promising as a platform for real-time applications.

grep 'potato:' file.txt | sed 's/^.*: //'

grep looks for any line that contains the string potato:, then, for each of these lines, sed replaces (s/// - substitute) any character (.*) from the beginning of the line (^) until the last occurrence of the sequence : (colon followed by space) with the empty string (s/...// - substitute the first part with the second part, which is empty).

or

grep 'potato:' file.txt | cut -d\   -f2

For each line that contains potato:, cut will split the line into multiple fields delimited by space (-d\ - d = delimiter, \ = escaped space character, something like -d" " would have also worked) and print the second field of each such line (-f2).

or

grep 'potato:' file.txt | awk '{print $2}'

For each line that contains potato:, awk will print the second field (print $2) which is delimited by default by spaces.

or

grep 'potato:' file.txt | perl -e 'for(<>){s/^.*: //;print}'

All lines that contain potato: are sent to an inline (-e) Perl script that takes all lines from stdin, then, for each of these lines, does the same substitution as in the first example above, then prints it.

or

awk '{if(/potato:/) print $2}' < file.txt

The file is sent via stdin (< file.txt sends the contents of the file via stdin to the command on the left) to an awk script that, for each line that contains potato: (if(/potato:/) returns true if the regular expression /potato:/ matches the current line), prints the second field, as described above.

or

perl -e 'for(<>){/potato:/ && s/^.*: // && print}' < file.txt

The file is sent via stdin (< file.txt, see above) to a Perl script that works similarly to the one above, but this time it also makes sure each line contains the string potato: (/potato:/ is a regular expression that matches if the current line contains potato:, and, if it does (&&), then proceeds to apply the regular expression described above and prints the result).

You can’t run arbitrary Python code in jinja; it doesn’t work like JSP in that regard (it just looks similar). All the things in jinja are custom syntax.

For your purpose, it would make most sense to define a custom filter, so you could for example do the following:

The grass is {{ variable1 | splitpart(0, ',') }} and the boat is {{  splitpart(1, ',') }}
Or just:
The grass is {{ variable1 | splitpart(0) }} and the boat is {{  splitpart(1) }}

The filter function could then look like this:

def splitpart (value, index, char = ','):
    return value.split(char)[index]

An alternative, which might make even more sense, would be to split it in the controller and pass the splitted list to the view.

Slightly longer version, but if you have to use pure Bash for some reason, you can use a while loop with an incrementing variable:

n=0; while [ $n -lt 100 ]; do n=$((n+1)); echo -n '='; done

The answers here were somewhat incomplete. And I had to compile information from other sources to actually acquire the plugin list.

1. Get the Jenkins CLI

The Jenkins CLI will allow us to interact with our Jenkins server from the command line. We can get it with a simple curl call.

curl 'localhost:8080/jnlpJars/jenkins-cli.jar' > jenkins-cli.jar

2. Create a Groovy script for parsing (thanks to malenkiy_scot)

Save the following as plugins.groovy.

def plugins = jenkins.model.Jenkins.instance.getPluginManager().getPlugins()
plugins.each {println "${it.getShortName()}: ${it.getVersion()}"}

3. Call the Jenkins API for plugin results

Call the Jenkins server (localhost:8080 here) with your login username and password while referencing the Groovy script:

java -jar jenkins-cli.jar -s http://localhost:8080 groovy --username "admin" --password "admin" = < plugins.groovy > plugins.txt

The output to plugins.txt looks like this:

#!/usr/bin/env python

import pandas as pd

# Make example dataframe
df = pd.DataFrame([(1, 'Germany'),
                   (2, 'France'),
                   (3, 'Indonesia'),
                   (4, 'France'),
                   (5, 'France'),
                   (6, 'Germany'),
                   (7, 'UK'),
                   ],
                  columns=['groupid', 'country'],
                  index=['a', 'b', 'c', 'd', 'e', 'f', 'g'])

# What you're looking for
values = df['country'].value_counts().keys().tolist()
counts = df['country'].value_counts().tolist()

Now, print(df['country'].value_counts()) gives:

France       3
Germany      2
UK           1
Indonesia    1

and print(values) gives:

['France', 'Germany', 'UK', 'Indonesia']

and print(counts) gives:

[3, 2, 1, 1]

Using POST

function DoAction( id, name )
{
    $.ajax({
         type: "POST",
         url: "someurl.php",
         data: "id=" + id + "&name=" + name,
         success: function(msg){
                     alert( "Data Saved: " + msg );
                  }
    });
}

Using GET

function DoAction( id, name )
{
     $.ajax({
          type: "GET",
          url: "someurl.php",
          data: "id=" + id + "&name=" + name,
          success: function(msg){
                     alert( "Data Saved: " + msg );
                   }
     });
}

EDIT:

A, perhaps, better way to do this that would work (using GET) if javascript were not enabled would be to generate the URL for the href, then use a click handler to call that URL via ajax instead.

<a href="/someurl.php?id=1&name=Jose" class="ajax-link"> Click </a>
<a href="/someurl.php?id=2&name=Juan" class="ajax-link"> Click </a>
<a href="/someurl.php?id=3&name=Pedro" class="ajax-link"> Click </a>
...
<a href="/someurl.php?id=n&name=xxx" class="ajax-link"> Click </a>

<script type="text/javascript">
$(function() {
   $('.ajax-link').click( function() {
         $.get( $(this).attr('href'), function(msg) {
              alert( "Data Saved: " + msg );
         });
         return false; // don't follow the link!
   });
});
</script>

You can't have multiple actions with the same name. You could add a parameter to one method and that would be valid. For example:

    public ActionResult Index(int i)
    {
        Some Code--Some Code---Some Code
        return View();
    }

There are a few ways to do to have actions that differ only by request verb. My favorite and, I think, the easiest to implement is to use the AttributeRouting package. Once installed simply add an attribute to your method as follows:

  [GET("Resources")]
  public ActionResult Index()
  {
      return View();
  }

  [POST("Resources")]
  public ActionResult Create()
  {
      return RedirectToAction("Index");
  }

In the above example the methods have different names but the action name in both cases is "Resources". The only difference is the request verb.

The package can be installed using NuGet like this:

PM> Install-Package AttributeRouting

If you don't want the dependency on the AttributeRouting packages you could do this by writing a custom action selector attribute.

                string BaseWindow = driver.CurrentWindowHandle;
                ReadOnlyCollection<string> handles = driver.WindowHandles;
                foreach (string handle in handles)
                {
                    if (handle != BaseWindow)
                    {
                        string title = driver.SwitchTo().Window(handle).Title;
                        Thread.Sleep(3000);
                        driver.SwitchTo().Window(handle).Title.Equals(title);
                        Thread.Sleep(3000);
                    }
                }

Coming from SQL Server as well, and this really bugged me. For those using Toad Data Point or Toad for Oracle, it's extremely simple. Just putting a colon in front of your variable name will prompt Toad to open a dialog where you enter the value on execute.

SELECT * FROM some_table WHERE some_column = :var_name;

According to the documentation:

$validator = Validator::make($request->all(), [
    'file' => 'max:500000',
]);

The value is in kilobytes. I.e. max:10240 = max 10 MB.
