try this

 @Html.DropDownListFor(model => model.UserName, new List<SelectListItem> 
   { new SelectListItem{Text="Active", Value="True",Selected =true },
     new SelectListItem{Text="Deactive", Value="False"}})

According to official documentation https://keras.io/getting-started/faq/#how-can-i-install-hdf5-or-h5py-to-save-my-models-in-keras

you can do :

first test if you have h5py installed by running the

import h5py

if you dont have errors while importing h5py you are good to save:

from keras.models import load_model

model.save('my_model.h5')  # creates a HDF5 file 'my_model.h5'
del model  # deletes the existing model

# returns a compiled model
# identical to the previous one
model = load_model('my_model.h5')

If you need to install h5py http://docs.h5py.org/en/latest/build.html

You're trying to create a tuple, but you're just parenthesizing a string :)

Add an extra ',':

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=(dRecieved,))  # <- note extra ','
processThread.start()

Or use brackets to make a list:

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=[dRecieved])  # <- 1 element list
processThread.start()

If you notice, from the stack trace: self.__target(*self.__args, **self.__kwargs)

The *self.__args turns your string into a list of characters, passing them to the processLine function. If you pass it a one element list, it will pass that element as the first argument - in your case, the string.

Based on the discussion in the comments (particularly from BalusC), it's probably not worth doing anything more complicated than this:

<script>var ctx = "${pageContext.request.contextPath}"</script>

Nouns.h doesn't include <string>, but it needs to. You need to add

#include <string>

at the top of that file, otherwise the compiler doesn't know what std::string is when it is encountered for the first time.

I've used xcode-select --install given in the accepted answer in previous major releases.

I've just upgraded to OS X 10.15 Catalina and run the Software Update tool from preferences again after the OS upgrade completed. The Xcode utilities update was available there, which also sorted the issue using git which had just output xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools)

I'm not sure there's a set standard, but I would have used 400 Bad Request, which the latest HTTP spec (from 2014) documents as follows:

6.5.1. 400 Bad Request

The 400 (Bad Request) status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).

To use an identity column in v10,

ALTER TABLE test 
ADD COLUMN id { int | bigint | smallint}
GENERATED { BY DEFAULT | ALWAYS } AS IDENTITY PRIMARY KEY;

For an explanation of identity columns, see https://blog.2ndquadrant.com/postgresql-10-identity-columns/.

For the difference between GENERATED BY DEFAULT and GENERATED ALWAYS, see https://www.cybertec-postgresql.com/en/sequences-gains-and-pitfalls/.

For altering the sequence, see https://popsql.io/learn-sql/postgresql/how-to-alter-sequence-in-postgresql/.

One of the benefits is that Razor views can be rendered inside unit tests, this is something that was not easily possible with the previous ASP.Net renderer.

From ScottGu's announcement this is listed as one of the design goals:

Unit Testable: The new view engine implementation will support the ability to unit test views (without requiring a controller or web-server, and can be hosted in any unit test project – no special app-domain required).

Another date format

select datediff(day,'20110101','20110301')

<a href="#" onClick="window.open('http://www.yahoo.com', '_blank')">test</a>

Easy as that.

Or without JS

<a href="http://yahoo.com" target="_blank">test</a>

You can always read the image file as grayscale right from the beginning using imread from OpenCV:

img = cv2.imread('messi5.jpg', 0)

Furthermore, in case you want to read the image as RGB, do some processing and then convert to Gray Scale you could use cvtcolor from OpenCV:

gray_image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

For me nothing worked, but this

add this line to your gitignore

*.xcuserdata

You either have to make the method Shared or use an instance of the class General:

Dim gen = New General()
gen.updateDynamics(get_prospect.dynamicsID)

or

General.updateDynamics(get_prospect.dynamicsID)

Public Shared Sub updateDynamics(dynID As Int32)
    ' ... '
End Sub

Shared(VB.NET)

I think @"^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$" should work.
You need to write it like

string email = txtemail.Text;
Regex regex = new Regex(@"^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$");
Match match = regex.Match(email);
if (match.Success)
    Response.Write(email + " is correct");
else
    Response.Write(email + " is incorrect");

Be warned that this will fail if:

1. There is a subdomain after the @ symbol.

2. You use a TLD with a length greater than 3, such as .info

To clarify some points:

As jro has mentioned, the right way is to use subprocess.communicate.

Yet, when feeding the stdin using subprocess.communicate with input, you need to initiate the subprocess with stdin=subprocess.PIPE according to the docs.

Note that if you want to send data to the process’s stdin, you need to create the Popen object with stdin=PIPE. Similarly, to get anything other than None in the result tuple, you need to give stdout=PIPE and/or stderr=PIPE too.

Also qed has mentioned in the comments that for Python 3.4 you need to encode the string, meaning you need to pass Bytes to the input rather than a string. This is not entirely true. According to the docs, if the streams were opened in text mode, the input should be a string (source is the same page).

If streams were opened in text mode, input must be a string. Otherwise, it must be bytes.

So, if the streams were not opened explicitly in text mode, then something like below should work:

import subprocess
command = ['myapp', '--arg1', 'value_for_arg1']
p = subprocess.Popen(command, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
output = p.communicate(input='some data'.encode())[0]

I've left the stderr value above deliberately as STDOUT as an example.

That being said, sometimes you might want the output of another process rather than building it up from scratch. Let's say you want to run the equivalent of echo -n 'CATCH\nme' | grep -i catch | wc -m. This should normally return the number characters in 'CATCH' plus a newline character, which results in 6. The point of the echo here is to feed the CATCH\nme data to grep. So we can feed the data to grep with stdin in the Python subprocess chain as a variable, and then pass the stdout as a PIPE to the wc process' stdin (in the meantime, get rid of the extra newline character):

import subprocess

what_to_catch = 'catch'
what_to_feed = 'CATCH\nme'

# We create the first subprocess, note that we need stdin=PIPE and stdout=PIPE
p1 = subprocess.Popen(['grep', '-i', what_to_catch], stdin=subprocess.PIPE, stdout=subprocess.PIPE)

# We immediately run the first subprocess and get the result
# Note that we encode the data, otherwise we'd get a TypeError
p1_out = p1.communicate(input=what_to_feed.encode())[0]

# Well the result includes an '\n' at the end, 
# if we want to get rid of it in a VERY hacky way
p1_out = p1_out.decode().strip().encode()

# We create the second subprocess, note that we need stdin=PIPE
p2 = subprocess.Popen(['wc', '-m'], stdin=subprocess.PIPE, stdout=subprocess.PIPE)

# We run the second subprocess feeding it with the first subprocess' output.
# We decode the output to convert to a string
# We still have a '\n', so we strip that out
output = p2.communicate(input=p1_out)[0].decode().strip()

This is somewhat different than the response here, where you pipe two processes directly without adding data directly in Python.

Hope that helps someone out.

Based on my experiments I found out that mysql insert statement with multiple value rows in single transaction is the fastest one.

However, if the data is too much then mysql's max_allowed_packet setting might restrict the single transaction insert with multiple value rows. Hence, following functions will fail when there is data greater than mysql's max_allowed_packet size:

1. singleTransactionInsertWithRollback
2. singleTransactionInsertWithPlaceholders
3. singleTransactionInsert

The most successful one in insert huge data scenario is transactionSpeed method, but it consumes time more the above mentioned methods. So, to handle this problem you can either split your data into smaller chunks and call single transaction insert multiple times or give up speed of execution by using transactionSpeed method.

Here's my research

The solution above not working for the latest version on PostgreSQL. I found this way to convert epoch time being stored in number and int column type is on PostgreSQL 13:

SELECT TIMESTAMP 'epoch' + (<table>.field::int) * INTERVAL '1 second' as started_on from <table>;

For more detail explanation, you can see here https://www.yodiw.com/convert-epoch-time-to-timestamp-in-postgresql/#more-214

You can use class loader which will read from classpath as ROOT path (without "/" in the beginning)

InputStream in = getClass().getClassLoader().getResourceAsStream("file.txt"); 
BufferedReader reader = new BufferedReader(new InputStreamReader(in));

This should work:

select * from mytable where 'Journal'=ANY(pub_types);

i.e. the syntax is <value> = ANY ( <array> ). Also notice that string literals in postresql are written with single quotes.

In the shell, you can't execute more than one statement at a time:

>>> x = 5
y = 6
SyntaxError: multiple statements found while compiling a single statement

You need to execute them one by one:

>>> x = 5
>>> y = 6
>>>

When you see multiple statements are being declared, that means you're seeing a script, which will be executed later. But in the interactive interpreter, you can't do more than one statement at a time.

Just because it is so difficult to find and it has to be spread: in mySQL this can be done much simpler, but I don't know if it works in other SQL.

SELECT * FROM `comments`
WHERE `comments`.`id` IN ('12','5','3','17')
ORDER BY FIELD(`comments`.`id`,'12','5','3','17')

The DI thing actually is some kind of strategy pattern. Whenever you want to be some logic/implementation exchangeable you typically find an interface and an appropriate setter method on the host class to wire your custom implementation of that interface.

It could be because of the property pageable -> pageSizes: true.

Remove this and check again.

you can make a javascript object with key being name of the html snippet, and value being an array of html strings, that are joined together.

var html = {
  top_crimes_template:
    [
      '<div class="top_crimes"><h3>Top Crimes</h3></div>',
      '<table class="crimes-table table table-responsive table-bordered">',
        '<tr>',
          '<th>',

          '</th>',
        '</tr>',
      '</table>'

            '<span class="list-heading">Players:</span>',
          '</th>',
          '<th>',

Starting in NumPy version 1.10, we have the method stack. It can stack arrays of any dimension (all equal):

# List of arrays.
L = [np.random.randn(5,4,2,5,1,2) for i in range(10)]

# Stack them using axis=0.
M = np.stack(L)
M.shape # == (10,5,4,2,5,1,2)
np.all(M == L) # == True

M = np.stack(L, axis=1)
M.shape # == (5,10,4,2,5,1,2)
np.all(M == L) # == False (Don't Panic)

# This are all true    
np.all(M[:,0,:] == L[0]) # == True
all(np.all(M[:,i,:] == L[i]) for i in range(10)) # == True

Enjoy,

Excellent question.

I'll explain it in the simplest way possible: Say you have 5 apples in your basket. Each of those apples is an object of type Apple, which has some characteristics (i.e. big, round, grows on trees).

In programming terms, you can have a class called Apple, which has variables size:big, shape:round, habitat:grows on trees. To have 5 apples in your basket, you need to instantiate 5 apples. Apple apple1, Apple apple2, Apple apple3 etc....

Alternatively: Objects are the definitions of something, instances are the physical things.

Does this make sense?

Try with this:

const { jasper } = this.state; //Gets the object from state
jasper.name = 'A new name'; //do whatever you want with the object
this.setState({jasper}); //Replace the object in state

Simply and clearly:

if (str == null || str.trim().length() == 0) {
    // str is empty
}

A good example for understanding "canonical form/representation" is to look at the XML schema datatype definition of "boolean":

• the "lexical representation" of boolean can be one of: {true, false, 1, 0} whereas
• the "canonical representation" can only be one of {true, false}

This, in essence, means that

• "true" and "1" get mapped to the canonical repr. "true" and
• "false" and "0" get mapped to the canoncial repr. "false"

see the w3 XML schema datatype definition for boolean

function NumberConvertToDecimal (number) {
    if (number == 0) {
       return '0.00'; 
    }
    number = parseFloat(number);
    number = number.toFixed(2).replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1");
    number = number.split('.').join('*').split('*').join('.');
    return number;
}

You can also accomplish this by breaking things up into separate logical statements by including & to separate the statements.

subset(my.df, my.df$v1 != "b" & my.df$v1 != "d" & my.df$v1 != "e")

This is not elegant and takes more code but might be more readable to newer R users. As pointed out in a comment above, subset is a "convenience" function that is best used when working interactively.

They are both the same functionally but the .min one has all unnecessary characters removed in order to make the file size smaller.

Just to point out as well, you are better using the minified version (.min) for your live environment as Google are now checking on page loading times. Having all your JS file minified means they will load faster and will score you more brownie points.

You can get an addon for Mozilla called Page Speed that will look through your site and show you all the .JS files and provide minified versions (amongst other things).

Use the FormBorderStyle property of your Form:

this.FormBorderStyle = FormBorderStyle.FixedDialog;

If you can't use the delay method as Robert Harvey suggested, you can use setTimeout.

Eg.

setTimeout(function() {$("#test").animate({"top":"-=80px"})} , 1500); // delays 1.5 sec
setTimeout(function() {$("#test").animate({"opacity":"0"})} , 1500 + 1000); // delays 1 sec after the previous one

Modify onClick() as follows:

@Override
public void onClick(View v) {
    if(v == btn) {
        canvas=sv.getHolder().lockCanvas();
        if(canvas!=null) {
            canvas.drawBitmap(bitmap, 100, 100, null);
            sv.getHolder().unlockCanvasAndPost(canvas);
        }
    } else if(v == btn1) {
        saveBitmapToInternalStorage(bitmap);
    }
}

There are several ways to enforce that btn must be pressed before btn1 so that the bitmap is painted before you attempt to save it.

I suggest that you initially disable btn1, and that you enable it when btn is clicked, like this:

if(v == btn) {
    ...
    btn1.setEnabled(true);
}

Be aware that running

import os
os.system("tzutil /s \"Central Standard Time\"");

will alter Windows system time, NOT just the local python environment time (so is definitley NOT the same as:

>>> os.environ['TZ'] = 'Europe/London'
>>> time.tzset()

which will only set in the current environment time (in Unix only)

Do Ctrl+alt+t and then:

1. sudo chmod 777 /opt/lampp/phpmyadmin/config.inc.php

2. open config.inc.php

3. test

   1. change config to cookie
      $cfg['Servers'][$i]['auth_type'] = 'config';
   2. donot change this
      $cfg['Servers'][$i]['user'] = 'root';
   3. change '' to 'root'
      $cfg['Servers'][$i]['password'] = '';

4. save config.inc.php

5. sudo chmod 644 /opt/lampp/phpmyadmin/config.inc.php

6. restart the xampp and check phpmyadmin

If it works i think i am glad to help you!!!

This is a bug in mysql-connector-java from version 5.1.33 to 5.1.37. I've reported it here: http://bugs.mysql.com/bug.php?id=79343

Edited: This has been corrected from mysql-connector-java 5.1.39

It was a typo in TimeUtil class in loadTimeZoneMappings method that raises a NPE locating /com/mysql/jdbc/TimeZoneMapping.properties file. If you look at the code, the file should be located within TimeUtil class loader, not TimeZone:

TimeUtil.class.getResourceAsStream(TIME_ZONE_MAPPINGS_RESOURCE);

The parameter useLegacyDatetimeCode allows to correct the difference between client and server timezones automatically when using dates. So it helps you precissely not having to specify timezones in each part. Althought using serverTimeZone parameter is a workaround, and meanwhile the patch is released, you can try better correcting the code by yourself as I did.

• If it's a standalone application, you can try simply to add a corrected com/mysql/jdbc/TimeUtil class to your code and be careful with jar loading order. This can help: https://owenou.com/2010/07/20/patching-with-class-shadowing-and-maven.html

• If it's a web application, the easier solution is to create your own mysql-connector-java-5.1.37-patched.jar, substituting the .class directly into the original jar.

I would use to table header tag below for a text in a table to make it standout from the rest of the table content.

 <table>

    <tr>
     <th>Dimension:</th>
    <td>98cm x 71cm</td>
    </tr>
   </table

Here is the simple clean protected route

const ProtectedRoute 
  = ({ isAllowed, ...props }) => 
     isAllowed 
     ? <Route {...props}/> 
     : <Redirect to="/authentificate"/>;
const _App = ({ lastTab, isTokenVerified })=> 
    <Switch>
      <Route exact path="/authentificate" component={Login}/>
      <ProtectedRoute 
         isAllowed={isTokenVerified} 
         exact 
         path="/secrets" 
         component={Secrets}/>
      <ProtectedRoute 
         isAllowed={isTokenVerified} 
         exact 
         path="/polices" 
         component={Polices}/>
      <ProtectedRoute 
         isAllowed={isTokenVerified} 
         exact 
         path="/grants" component={Grants}/>
      <Redirect from="/" to={lastTab}/>
    </Switch>

isTokenVerified is a method call to check the authorization token basically it returns boolean.

To calculate log base 2 of n, following expression can be used:

double res = log10(n)/log10(2);

You don't need a batch file, just do this from powershell :

powershell -C "gci | % {rni $_.Name ($_.Name -replace 'Vacation2010', 'December')}"

You can use the excecl command

int execl(const char *path, const char *arg, ...);

Like shown here

#include <stdio.h>
#include <unistd.h>
#include <dirent.h>

int main (void) {

   return execl ("/bin/pwd", "pwd", NULL);

}

The second argument will be the name of the process as it will appear in the process table.

Alternatively, you can use the getcwd() function to get the current working directory:

#include <stdio.h>
#include <unistd.h>
#include <dirent.h>
#define MAX 255

int main (void) {
char wd[MAX];
wd[MAX-1] = '\0';

if(getcwd(wd, MAX-1) == NULL) {
  printf ("Can not get current working directory\n");
}
else {
  printf("%s\n", wd);
}
  return 0;
}

join() is a instance method of java.lang.Thread class which we can use join() method to ensure all threads that started from main must end in order in which they started and also main should end in last. In other words waits for this thread to die.

Exception: join() method throws InterruptedException.

Thread state: When join() method is called on thread it goes from running to waiting state. And wait for thread to die.

synchronized block: Thread need not to acquire object lock before calling join() method i.e. join() method can be called from outside synchronized block.

Waiting time: join(): Waits for this thread to die.

public final void join() throws InterruptedException;

This method internally calls join(0). And timeout of 0 means to wait forever;

join(long millis) – synchronized method Waits at most millis milliseconds for this thread to die. A timeout of 0 means to wait forever.

public final synchronized void join(long millis)
    throws InterruptedException;

public final synchronized void join(long millis, int nanos)
    throws InterruptedException;

Example of join method

class MyThread implements Runnable {
     public void run() {
           String threadName = Thread.currentThread().getName();
           Printer.print("run() method of "+threadName);
           for(int i=0;i<4;i++){
                Printer.print("i="+i+" ,Thread="+threadName);
           }         
     }
}

public class TestJoin {
     public static void main(String...args) throws InterruptedException {
           Printer.print("start main()...");

           MyThread runnable = new MyThread();
           Thread thread1=new Thread(runnable);
           Thread thread2=new Thread(runnable);

           thread1.start();
           thread1.join();

           thread2.start();
           thread2.join();

           Printer.print("end main()");
     }
}

class Printer {
     public static void print(String str) {
           System.out.println(str);
     }
}

Output:
     start main()...
     run() method of Thread-0
     i=0 ,Thread=Thread-0
     i=1 ,Thread=Thread-0
     i=2 ,Thread=Thread-0
     i=3 ,Thread=Thread-0
     run() method of Thread-1
     i=0 ,Thread=Thread-1
     i=1 ,Thread=Thread-1
     i=2 ,Thread=Thread-1
     i=3 ,Thread=Thread-1
     end main()

Note: calling thread1.join() made main thread to wait until Thread-1 dies.

Let’s check a program to use join(long millis)

First, join(1000) will be called on Thread-1, but once 1000 millisec are up, main thread can resume and start thread2 (main thread won’t wait for Thread-1 to die).

class MyThread implements Runnable {
     public void run() {
           String threadName = Thread.currentThread().getName();
           Printer.print("run() method of "+threadName);
           for(int i=0;i<4;i++){
                try {
                     Thread.sleep(500);
                } catch (InterruptedException e) {
                     e.printStackTrace();
                }
                Printer.print("i="+i+" ,Thread="+threadName);
           }         
     }
}

public class TestJoin {
     public static void main(String...args) throws InterruptedException {
           Printer.print("start main()...");

           MyThread runnable = new MyThread();
           Thread thread1=new Thread(runnable);
           Thread thread2=new Thread(runnable);

           thread1.start();

           // once 1000 millisec are up,
           // main thread can resume and start thread2.
           thread1.join(1000);

           thread2.start();
           thread2.join();

           Printer.print("end main()");
     }
}

class Printer {
     public static void print(String str) {
           System.out.println(str);
     }
}

Output:
     start main()...
     run() method of Thread-0
     i=0 ,Thread=Thread-0
     run() method of Thread-1
     i=1 ,Thread=Thread-0
     i=2 ,Thread=Thread-0
     i=0 ,Thread=Thread-1
     i=1 ,Thread=Thread-1
     i=3 ,Thread=Thread-0
     i=2 ,Thread=Thread-1
     i=3 ,Thread=Thread-1
     end main()

According to RFC 2616 (HTTP/1.1) 403 is sent when:

The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in the entity. If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead

In other words, if the client CAN get access to the resource by authenticating, 401 should be sent.

in parent.html:

<script type="text/javascript">
    $(document).ready(function () {
        var output = "data";
        var OpenWindow = window.open("child.html", "mywin", '');
        OpenWindow.dataFromParent = output; // dataFromParent is a variable in child.html
        OpenWindow.init();
    });
</script>

in child.html:

<script type="text/javascript">
    var dataFromParent;    
    function init() {
        document.write(dataFromParent);
    }
</script>

Too hard? Your TA is... well, the phrase would probably get me banned. Anyways, check to see if numb is negative. If it is then multiply numa by -1 and do numb = abs(numb). Then do the loop.

Declaration in config/app.php under aliases:-

'Input' => Illuminate\Support\Facades\Input::class,

Or You can import Input facade directly as required,

use Illuminate\Support\Facades\Input;

or

use Illuminate\Support\Facades\Input as input;

Generally speaking, for boolean or bit data types, you would use 0 or 1 like so:

UPDATE tbl SET bitCol = 1 WHERE bitCol = 0

Quote from official documentation as of August 2013:

User-created libraries as of version 0017 go in a subdirectory of your default sketch directory. For example, on OSX, the new directory would be ~/Documents/Arduino/libraries/. On Windows, it would be My Documents\Arduino\libraries\. To add your own library, create a new directory in the libraries directory with the name of your library. The folder should contain a C or C++ file with your code and a header file with your function and variable declarations. It will then appear in the Sketch | Import Library menu in the Arduino IDE.

To remove a library, stop the Arduino IDE and remove the library directory from the aforementioned location.

The accepted answer uses the Apache Commons package but this is how I did it using Java's native libraries

Java 11 and up

import java.util.Base64;

public class Base64Encoding {

    public static void main(String[] args) {
        Base64.Encoder enc = Base64.getEncoder();
        Base64.Decoder dec = Base64.getDecoder();
        String str = "77+9x6s=";

        // encode data using BASE64
        String encoded = enc.encodeToString(str.getBytes());
        System.out.println("encoded value is \t" + encoded);

        // Decode data
        String decoded = new String(dec.decode(encoded));
        System.out.println("decoded value is \t" + decoded);
        System.out.println("original value is \t" + str);
    }
}

Java 6 - 10

import java.io.UnsupportedEncodingException;    
import javax.xml.bind.DatatypeConverter;

public class EncodeString64 {
    public static void main(String[] args) throws UnsupportedEncodingException {

        String str = "77+9x6s=";
        // encode data using BASE64
        String encoded = DatatypeConverter.printBase64Binary(str.getBytes());
        System.out.println("encoded value is \t" + encoded);

        // Decode data 
        String decoded = new String(DatatypeConverter.parseBase64Binary(encoded));
        System.out.println("decoded value is \t" + decoded);

        System.out.println("original value is \t" + str);
    }
}

The better way would be to try/catch the encoding/decoding steps but hopefully you get the idea.

1. Run a small web server on the client machine. Can be a small 100kb thing. A Python / Perl script, etc.
2. Include a small, pre-compiled C executable that can move the mouse.

3. Run it as a CGI-script via a simple http call, AJAX, whatever - with the coordinates you want to move the mouse to, eg:

   http://localhost:9876/cgi/mousemover?x=200&y=450

PS: For any problem, there are hundreds of excuses as to why, and how - it can't, and shouldn't - be done.. But in this infinite universe, it's really just a matter of determination - as to whether YOU will make it happen.

Normally, for every connecting client the server forks a child process that communicates with the client (TCP). The parent server hands off to the child process an established socket that communicates back to the client.

When you send the data to a socket from your child server, the TCP stack in the OS creates a packet going back to the client and sets the "from port" to 80.

Better yet, let's say I want to remove everything under the C:\windows\temp folder.

@echo off
rd C:\windows\temp /s /q

var yearStart = 2000;
var yearEnd = 2040;

var arr = [];

for (var i = yearStart; i <= yearEnd; i++) {

     arr.push(i);
}

Something like this should do the trick

<select id="leave" onchange="leaveChange()">
  <option value="5">Get Married</option>
  <option value="100">Have a Baby</option>
  <option value="90">Adopt a Child</option>
  <option value="15">Retire</option>
  <option value="15">Military Leave</option>
  <option value="15">Medical Leave</option>
</select>

<div id="message"></div>

Javascript

function leaveChange() {
    if (document.getElementById("leave").value != "100"){
        document.getElementById("message").innerHTML = "Common message";
    }     
    else{
        document.getElementById("message").innerHTML = "Having a Baby!!";
    }        
}

jsFiddle Demo

A shorter version and more general could be

HTML

<select id="leave" onchange="leaveChange(this)">
  <option value="5">Get Married</option>
  <option value="100">Have a Baby</option>
  <option value="90">Adopt a Child</option>
  <option value="15">Retire</option>
  <option value="15">Military Leave</option>
  <option value="15">Medical Leave</option>
</select>

Javascript

function leaveChange(control) {
    var msg = control.value == "100" ? "Having a Baby!!" : "Common message";
    document.getElementById("message").innerHTML = msg;
}

JDS's answer worked best. C# example loading image:

• Include the image as Resource (Project tree->Resources, right click to add the desirable file ImageName.png)
• Embedded Resource (Project tree->Resources->ImageName.png, right click select properties)
• .png file format (.bmp .jpg should also be OK)

pictureBox1.Image = ProjectName.Properties.Resources.ImageName;

Note the followings:

• The resource image file is "ImageName.png", file extension should be omitted.
• ProjectName may perhaps be more adequately understood as "Assembly name", which is to be the respective text entry on the Project->Properties page.

The example code line is run successfully using VisualStudio 2015 Community.

Streams are often accessed by threads that periodically empty their content and, for example, display it on the screen, send it to a socket or write it to a file. This is done for performance reasons. Flushing an output stream means that you want to stop, wait for the content of the stream to be completely transferred to its destination, and then resume execution with the stream empty and the content sent.

This should do it:

UPDATE ProductReviews
SET    ProductReviews.status = '0'
FROM   ProductReviews
       INNER JOIN products
         ON ProductReviews.pid = products.id
WHERE  ProductReviews.id = '17190'
       AND products.shopkeeper = '89137'

^{All the information is in the existing answers, but I personally wished for a concise summary, so here's an attempt at it; the commands use int variables for brevity, but they apply analogously to any type, including string.}

To declare multiple variables and:

• either: initialize them each:

int i = 0, j = 1; // declare and initialize each; `var` is NOT supported as of C# 8.0

• or: initialize them all to the same value:

int i, j;    // *declare* first (`var` is NOT supported)
i = j = 42;  // then *initialize* 

// Single-statement alternative that is perhaps visually less obvious:
// Initialize the first variable with the desired value, then use 
// the first variable to initialize the remaining ones.
int i = 42, j = i, k = i;

What doesn't work:

• You cannot use var in the above statements, because var only works with (a) a declaration that has an initialization value (from which the type can be inferred), and (b), as of C# 8.0, if that declaration is the only one in the statement (otherwise you'll get compilation error error CS0819: Implicitly-typed variables cannot have multiple declarators).

• Placing an initialization value only after the last variable in a multiple-declarations statement initializes the last variable only:

  int i, j = 1;// initializes *only* j

Since C++ 17 (VS2015) you can use the standard for read-write locks:

#include <shared_mutex>

typedef std::shared_mutex Lock;
typedef std::unique_lock< Lock > WriteLock;
typedef std::shared_lock< Lock > ReadLock;

Lock myLock;


void ReadFunction()
{
    ReadLock r_lock(myLock);
    //Do reader stuff
}

void WriteFunction()
{
     WriteLock w_lock(myLock);
     //Do writer stuff
}

For older version, you can use boost with the same syntax:

#include <boost/thread/locks.hpp>
#include <boost/thread/shared_mutex.hpp>

typedef boost::shared_mutex Lock;
typedef boost::unique_lock< Lock >  WriteLock;
typedef boost::shared_lock< Lock >  ReadLock;

Check out Loom (http://theengine.co) is a new cross platform 2D game engine featuring hot swapping code & assets on devices. This means that you can work in Photoshop on your assets, you can update your code, modify the UI of your app/game and then see the changes on your device(s) while the app is running.

Thinking to the other cross platform game engines I’ve heard of or even played with, the Loom Game Engine is by far the best in my oppinion with lots of great features. Most of the other similar game engines (Corona SDK, MOAI SDK, Gideros Mobile) are Lua based (with an odd syntax, at least for me). The Loom Game Engine uses LoomScripts, a scripting language inspired from ActionScript 3, with a couple of features borrowed from C#. If you ever developed in ActionScript 3, C# or Java, LoomScript will look familiar to you (and I’m more comfortable with this syntax than with Lua’s syntax).

The 1 year license for the Loom Game Engine costs $500, and I think it’s an affordable price for any indie game developer. Couple of weeks ago the offered a 1 year license for free too. After the license expires, you can still use Loom to create and deploy your own games, but you won’t get any further updates. The creators of Loom are very confident and they promised to constantly improve their baby making it worthwile to purchase another license.

Without further ado, here are Loom’s great features:

1. Cross platform (iOS, Android, OS X, Windows, Linux/Ubuntu)

2. Rails-inspired workflow lets you spend your time working with your game (one command to create a new project, and another command to run it)

3. Fast compiler

4. Live code and assets editing

5. Possibility to integrate third party libraries

6. Uses Cocos2DX for rendering

7. XML, JSON support

8. LML (markup language) and CSS for styling UI elements

9. UI library

10. Dependency injection

11. Unit test framework

12. Chipmunk physics

13. Seeing your changes live makes multidevice development easy

14. Small download size

15. Built for teams

Postgres has a very rich system catalog exposed via SQL tables. PG's statistics collector is a subsystem that supports collection and reporting of information about server activity.

Now to figure out the blocking PIDs you can simply query pg_stat_activity.

select pg_blocking_pids(pid) as blocked_by
from pg_stat_activity
where cardinality(pg_blocking_pids(pid)) > 0;

To, get the query corresponding to the blocking PID, you can self-join or use it as a where clause in a subquery.

SELECT query
FROM pg_stat_activity
WHERE pid IN (select unnest(pg_blocking_pids(pid)) as blocked_by from pg_stat_activity where cardinality(pg_blocking_pids(pid)) > 0);

Note: Since pg_blocking_pids(pid) returns an Integer[], so you need to unnest it before you use it in a WHERE pid IN clause.

Hunting for slow queries can be tedious sometimes, so have patience. Happy hunting.

I just read the source code for ImageView and it is basically impossible without using the subclassing solutions in this thread. In ImageView.onMeasure we get to these lines:

        // Get the max possible width given our constraints
        widthSize = resolveAdjustedSize(w + pleft + pright, mMaxWidth, widthMeasureSpec);

        // Get the max possible height given our constraints
        heightSize = resolveAdjustedSize(h + ptop + pbottom, mMaxHeight, heightMeasureSpec);

Where h and w are the dimensions of the image, and p* is the padding.

And then:

private int resolveAdjustedSize(int desiredSize, int maxSize,
                               int measureSpec) {
    ...
    switch (specMode) {
        case MeasureSpec.UNSPECIFIED:
            /* Parent says we can be as big as we want. Just don't be larger
               than max size imposed on ourselves.
            */
            result = Math.min(desiredSize, maxSize);

So if you have a layout_height="wrap_content" it will set widthSize = w + pleft + pright, or in other words, the maximum width is equal to the image width.

This means that unless you set an exact size, images are NEVER enlarged. I consider this to be a bug, but good luck getting Google to take notice or fix it. Edit: Eating my own words, I submitted a bug report and they say it has been fixed in a future release!

Another solution

Here is another subclassed workaround, but you should (in theory, I haven't really tested it much!) be able to use it anywhere you ImageView. To use it set layout_width="match_parent", and layout_height="wrap_content". It is quite a lot more general than the accepted solution too. E.g. you can do fit-to-height as well as fit-to-width.

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ImageView;

// This works around the issue described here: http://stackoverflow.com/a/12675430/265521
public class StretchyImageView extends ImageView
{

    public StretchyImageView(Context context)
    {
        super(context);
    }

    public StretchyImageView(Context context, AttributeSet attrs)
    {
        super(context, attrs);
    }

    public StretchyImageView(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
    {
        // Call super() so that resolveUri() is called.
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        // If there's no drawable we can just use the result from super.
        if (getDrawable() == null)
            return;

        final int widthSpecMode = MeasureSpec.getMode(widthMeasureSpec);
        final int heightSpecMode = MeasureSpec.getMode(heightMeasureSpec);

        int w = getDrawable().getIntrinsicWidth();
        int h = getDrawable().getIntrinsicHeight();
        if (w <= 0)
            w = 1;
        if (h <= 0)
            h = 1;

        // Desired aspect ratio of the view's contents (not including padding)
        float desiredAspect = (float) w / (float) h;

        // We are allowed to change the view's width
        boolean resizeWidth = widthSpecMode != MeasureSpec.EXACTLY;

        // We are allowed to change the view's height
        boolean resizeHeight = heightSpecMode != MeasureSpec.EXACTLY;

        int pleft = getPaddingLeft();
        int pright = getPaddingRight();
        int ptop = getPaddingTop();
        int pbottom = getPaddingBottom();

        // Get the sizes that ImageView decided on.
        int widthSize = getMeasuredWidth();
        int heightSize = getMeasuredHeight();

        if (resizeWidth && !resizeHeight)
        {
            // Resize the width to the height, maintaining aspect ratio.
            int newWidth = (int) (desiredAspect * (heightSize - ptop - pbottom)) + pleft + pright;
            setMeasuredDimension(newWidth, heightSize);
        }
        else if (resizeHeight && !resizeWidth)
        {
            int newHeight = (int) ((widthSize - pleft - pright) / desiredAspect) + ptop + pbottom;
            setMeasuredDimension(widthSize, newHeight);
        }
    }

Alt+F4 is working only in brackets

SendKeys.SendWait("(%{F4})");

I use DataGridView with VirtualMode=true and only this option worked for me (when both the mouse and the space bar are working, including repeated space clicks):

private void doublesGridView_CurrentCellDirtyStateChanged(object sender, EventArgs e)
{
   var data_grid = (DataGridView)sender;
      
   if (data_grid.CurrentCell.IsInEditMode && data_grid.IsCurrentCellDirty) {
      data_grid.EndEdit();            
   }
}

private void doublesGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
   if (e.ColumnIndex == CHECKED_COLUMN_NUM && e.RowIndex >= 0 && e.RowIndex < view_objects.Count) { // view_objects - pseudocode   
     view_objects[e.RowIndex].marked = !view_objects[e.RowIndex].marked;        // Invert the state of the displayed object
   }
}  

Like this:

#include <vector>

// ...

std::vector<std::vector<int>> A(dimension, std::vector<int>(dimension));

(Pre-C++11 you need to leave whitespace between the angled brackets.)

Save it as a .ps1 file and then execute

powershell -file "path\to your\start stop nation service command file.ps1"

See here: http://docs.python.org/using/windows.html

pythonw.exe "This suppresses the terminal window on startup."

To start, using the same ID twice is not a good idea. ID's should be unique, if you need to style elements you should use a class to apply CSS instead.

At last, you defined the name of your submit button as Tea and Coffee, but in your PHP you are using submit as index. your index should have been $_POST['Tea'] for example. that would require you to check for it being set as it only sends one , you can do that with isset().

Buy anyway , user4035 just beat me to it , his code will "fix" this for you.

print('{:02}'.format(1))
print('{:02}'.format(10))
print('{:02}'.format(100))

prints:

01
10
100

It's the identifier for your current session in PHP. If you delete it, you won't be able to access/make use of session variables. I'd suggest you keep it.

I have read this old post, and I would like to provide another solution.

The problem with running Application.Undo is that Woksheet_Change runs again. We have the same problem when we restore.

To avoid that, I use a piece of code to avoid the second steps through Worksheet_Change.

Before we begin, we must create a Boolean static variable BlnAlreadyBeenHere, to tell Excel not to run Worksheet_Change again

Here you can see it:

    Private Sub Worksheet_Change(ByVal Target As Range)

    Static blnAlreadyBeenHere As Boolean

    'This piece avoid to execute Worksheet_Change again
    If blnAlreadyBeenHere Then
        blnAlreadyBeenHere = False
        Exit Sub
    End If

    'Now, we will store the old and new value
    Dim vOldValue As Variant
    Dim vNewValue As Variant

    'To store new value
    vNewValue = Target.Value

    'Undo to retrieve old value

    'To avoid new Worksheet_Change execution
    blnAlreadyBeenHere = True

    Application.Undo

    'To store old value
    vOldValue = Target.Value

    'To rewrite new value

    'To avoid new Worksheet_Change execution agein
    blnAlreadyBeenHere = True
    Target.Value = vNewValue

    'Done! I've two vaules stored
    Debug.Print vOldValue, vNewValue

End Sub

The advantage of this method is that it is not necessary to run Worksheet_SelectionChange.

If we want the routine to work from another module, we just have to take the declaration of the variable blnAlreadyBeenHere out of the routine, and declare it with Dim.

Same operation with vOldValue and vNewValue, in the header of a module

Dim blnAlreadyBeenHere As Boolean
Dim vOldValue As Variant
Dim vNewValue As Variant

To solve problems like this I'm using CSS - fastest & simplest way I think... Just modify it by your needs...

@media only screen and (max-width: 480px) {
    #your_id {width:000px;height:000px;}
}
@media only screen and (min-width: 480px) and (max-width: 768px) {
    #your_id {width:000px;height:000px;}
}
@media only screen and (min-width: 768px) and (max-width: 959px) {
    #your_id {width:000px;height:000px;}
}
@media only screen and (min-width: 959px) {
    #your_id {width:000px;height:000px;}
}

static before a global variable means that this variable is not accessible from outside the compilation module where it is defined.

E.g. imagine that you want to access a variable in another module:

foo.c

int var; // a global variable that can be accessed from another module
// static int var; means that var is local to the module only.
...

bar.c

extern int var; // use the variable in foo.c
...

Now if you declare var to be static you can't access it from anywhere but the module where foo.c is compiled into.

Note, that a module is the current source file, plus all included files. i.e. you have to compile those files separately, then link them together.

According to RFC2965 3.3.1 (which might or might not be followed by browsers), unless the port is explicitly specified via the port parameter of the Set-Cookie header, cookies might or might not be sent to any port.

Google's Browser Security Handbook says: by default, cookie scope is limited to all URLs on the current host name - and not bound to port or protocol information. and some lines later There is no way to limit cookies to a single DNS name only [...] likewise, there is no way to limit them to a specific port. (Also, keep in mind, that IE does not factor port numbers into its same-origin policy at all.)

So it does not seem to be safe to rely on any well-defined behavior here.

You can't pass a parameter in a @selector().

It looks like you're trying to implement a callback. The best way to do that would be something like this:

[object setCallbackObject:self withSelector:@selector(myMethod:)];

Then in your object's setCallbackObject:withSelector: method: you can call your callback method.

-(void)setCallbackObject:(id)anObject withSelector:(SEL)selector {
    [anObject performSelector:selector];
}

sorted(list, key=lambda x: x[1])

Note: this works on time variable too.

SOLUTION: dude all you need is an XServer & X11 forwarding enabled. I use XMing (XServer). You are already enabling X11 forwarding. Just Install it(XMing) and keep it running when you create the session with PuTTY.

alternative solution for this with using many infowindows: save prev opened infowindow in a variable and then close it when new window opened

var prev_infowindow =false; 
...
base.attachInfo = function(marker, i){
    var infowindow = new google.maps.InfoWindow({
        content: 'yourmarkerinfocontent'
    });

    google.maps.event.addListener(marker, 'click', function(){
        if( prev_infowindow ) {
           prev_infowindow.close();
        }

        prev_infowindow = infowindow;
        infowindow.open(base.map, marker);
    });
}

<meta name="language" content="Spanish">

This isn't defined in any specification (including the HTML5 draft)

<meta http-equiv="content-language" content="es">

This is a poor man's version of a real HTTP header and should really be expressed in the headers. For example:

Content-language: es
Content-type: text/html;charset=UTF-8

It says that the document is intended for Spanish language speakers (it doesn't, however mean the document is written in Spanish; it could, for example, be written in English as part of a language course for Spanish speakers).

From the spec:

The Content-Language entity-header field describes the natural language(s) of the intended audience for the enclosed entity. Note that this might not be equivalent to all the languages used within the entity-body.

If you want to state that a document is written in Spanish then use:

<html lang="es">

CSV files have no limit of rows you can add to them. Excel won't hold more that the 1 million lines of data if you import a CSV file having more lines.

Excel will actually ask you whether you want to proceed when importing more than 1 million data rows. It suggests to import the remaining data by using the text import wizard again - you will need to set the appropriate line offset.

If downgrading from pip version 10 because of PyCharm manage.py or other python errors:

python -m pip install pip==9.0.1

do wget -r -l0 www.oldsite.com

Then just find www.oldsite.com would reveal all urls, I believe.

Alternatively, just serve that custom not-found page on every 404 request! I.e. if someone used the wrong link, he would get the page telling that page wasn't found, and making some hints about site's content.

I didn't find it listed so updating the list.

You need to have the apk installed and running in front on your phone for this solution:

Windows CMD line:

adb shell dumpsys window windows | findstr <any unique string from your pkg Name>

Linux Terminal:

adb shell dumpsys window windows | grep -i <any unique string from your Pkg Name>

OUTPUT for Calculator package would be:

Window #7 Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}:

    mOwnerUid=10036 mShowToOwnerOnly=true package=com.android.calculator2 appop=NONE

    mToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    mRootToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    mAppToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    WindowStateAnimator{3e160d22 com.android.calculator2/com.android.calculator2.Calculator}:

      mSurface=Surface(name=com.android.calculator2/com.android.calculator2.Calculator)

  mCurrentFocus=Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}

  mFocusedApp=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

Main part is, First Line:

Window #7 Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}:

First part of the output is package name:

com.android.calculator2

Second Part of output (which is after /) can be two things, in our case its:

com.android.calculator2.Calculator

1. <PKg name>.<activity name> = <com.android.calculator2>.<Calculator>

   so .Calculator is our activity

2. If second part is entirely different from Package name and doesn't seem to contain pkg name which was before / in out output, then entire second part can be used as main activity.

As mentioned above, ConstraintLayout offers maximum height for its children via:

app:layout_constraintHeight_max="300dp"
app:layout_constrainedHeight="true"

Besides, if maximum height for one ConstraintLayout's child is uncertain until App running, there still has a way to make this child automatically adapt a mutable height no matter where it was placed in the vertical chain.

For example, we need to show a bottom dialog with a mutable header TextView, a mutable ScrollView and a mutable footer TextView. The dialog's max height is 320dp,when total height not reach 320dp ScrollView act as wrap_content, when total height exceed ScrollView act as "maxHeight=320dp - header height - footer height".

We can achieve this just through xml layout file:

<?xml version="1.0" encoding="utf-8"?>

Most import code is short:

app:layout_constraintVertical_bias="1"
app:layout_constraintVertical_chainStyle="packed"

app:layout_constrainedHeight="true"

Horizontal maxWidth usage is quite the same.

There is also a way of configuring Git so, it always pulls and pushes the equivalent remote branch to the branch currently checked out to the working copy. It's called a tracking branch which git ready recommends setting by default.

For the next repository above the present working directory:

git config branch.autosetupmerge true

For all Git repositories, that are not configured otherwise:

git config --global branch.autosetupmerge true

Kind of magic, IMHO but this might help in cases where the specific branch is always the current branch.

When you have branch.autosetupmerge set to true and checkout a branch for the first time, Git will tell you about tracking the corresponding remote branch:

(master)$ git checkout gh-pages
Branch gh-pages set up to track remote branch gh-pages from origin.
Switched to a new branch 'gh-pages'

Git will then push to that corresponding branch automatically:

(gh-pages)$ git push

I use a piece of software called Navicat to :

• Sync Live databases to my test databases.
• Show differences between the two databases.

It costs money, it's windows and mac only, and it's got a whacky UI, but I like it.

Make sure to indicate lineterinator='\n' when create the writer; otherwise, an extra empty line might be written into file after each data line when data sources are from other csv file...

Here is my solution:

with open('csvfile', 'a') as csvfile:
    spamwriter = csv.writer(csvfile, delimiter='    ',quotechar='|', quoting=csv.QUOTE_MINIMAL, lineterminator='\n')
for i in range(0, len(data)):
    spamwriter.writerow(data[i])

Here's an example - we recently developed a simulation model to measure the remote transmission response time of a yet-to-be-developed system. An emulation analysis would not have given us the answer in time to upgrade the bandwidth capacity so simulation was our approach. Because we were mostly interested in determining bandwidth needs, we cared primarily about transaction size and volume, not the processing of the system. The simulation model was on a stand-alone piece of software that was designed to model discrete-event processes. To summarize in response to your question, emulation is a type of simulation. But, in this case, simulation was NOT an emulation because it didn't fully represent the new system, only the size and volume of transactions.

I don't know if Boost has more specific functions, but you can do it with the standard library.

Given std::vector<double> v, this is the naive way:

#include <numeric>

double sum = std::accumulate(v.begin(), v.end(), 0.0);
double mean = sum / v.size();

double sq_sum = std::inner_product(v.begin(), v.end(), v.begin(), 0.0);
double stdev = std::sqrt(sq_sum / v.size() - mean * mean);

This is susceptible to overflow or underflow for huge or tiny values. A slightly better way to calculate the standard deviation is:

double sum = std::accumulate(v.begin(), v.end(), 0.0);
double mean = sum / v.size();

std::vector<double> diff(v.size());
std::transform(v.begin(), v.end(), diff.begin(),
               std::bind2nd(std::minus<double>(), mean));
double sq_sum = std::inner_product(diff.begin(), diff.end(), diff.begin(), 0.0);
double stdev = std::sqrt(sq_sum / v.size());

UPDATE for C++11:

The call to std::transform can be written using a lambda function instead of std::minus and std::bind2nd(now deprecated):

std::transform(v.begin(), v.end(), diff.begin(), [mean](double x) { return x - mean; });

List does not implement IBindingList so the grid does not know about your new items.

Bind your DataGridView to a BindingList<T> instead.

var list = new BindingList<Person>(persons);
myGrid.DataSource = list;

But I would even go further and bind your grid to a BindingSource

var list = new List<Person>()
{
    new Person { Name = "Joe", },
    new Person { Name = "Misha", },
};
var bindingList = new BindingList<Person>(list);
var source = new BindingSource(bindingList, null);
grid.DataSource = source;

In your xml file add something like this with width and height as 'match_parent'.

<RelativeLayout
        android:id="@+id/bac_dim_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#C0000000"
        android:visibility="gone" >
</RelativeLayout>

In your activity oncreate

//setting background dim when showing popup
back_dim_layout = (RelativeLayout) findViewById(R.id.share_bac_dim_layout);

Finally make visible when you show your popupwindow and make its visible gone when you exit popupwindow.

back_dim_layout.setVisibility(View.VISIBLE);
back_dim_layout.setVisibility(View.GONE);

If you want to click on all elements selected by some class, you can use this example (used on last.fm on the Loved tracks page to Unlove all).

var divs = document.querySelectorAll('.love-button.love-button--loved'); 

for (i = 0; i < divs.length; ++i) {
  divs[i].click();
};

With ES6 and Babel (cannot be run in the browser console directly)

[...document.querySelectorAll('.love-button.love-button--loved')]
   .forEach(div => { div.click(); })

In new updated eclipse the option "create project from existing source" is found here, File>New>Project>Android>Android Project from Existing Code. Then browse to root directory.

You just want to call an external URL and use the results? PHP does this out of the box, if we're talking about a simple GET request to something serving JSON:

$json = json_decode(file_get_contents('http://host.com/api/stuff/1'), true);

If you want to do a post request, it's a little harder but there's loads of examples how to do this with curl.

So I guess the question is; what exactly do you want?

Check out the manual: http://www.php.net/manual/en/datetime.format.php

<?php
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:s');
?>

Will output: 2000-01-01 00:00:00

It doesn't work because it doesn't make sense (so little sense that HTML 5 explicitly forbids it).

To fix it, decide if you want a link or a submit button and use whichever one you actually want (Hint: You don't have a form, so a submit button is nonsense).

According to the Richardson maturity model, the question is not REST vs. RPC, but how much REST?

In this view, the compliance to REST standard can be classified in 4 levels.

• level 0: think in terms of actions and parameters. As the article explains, this is essentially equivalent to JSON-RPC (the article explains it for XML-RPC, but same arguments hold for both).
• level 1: think in terms of resources. Everything relevant to a resource belong to the same URL
• level 2: use HTTP verbs
• level 3: HATEOAS

According to the creator of REST standard, only level 3 services can be called RESTful. However, this is a metric of compliance, not quality. If you just want to call a remote function that does a calculation, it probably makes no sense to have relevant hypermedia links in the response, neither differentiation of behavior based on the HTTP verb used. So, a such call inherently tends to be more RPC-like. However, lower compliance level does not necessarily mean statefulness, or higher coupling. Probably, instead of thinking REST vs. RPC, you should use as much REST as possible, but no more. Do not twist your application just to fit with the RESTful compliance standards.

I'd say export your server config in IIS manager:

1. In IIS manager, click the Server node
2. Go to Shared Configuration under "Management"
3. Click “Export Configuration”. (You can use a password if you are sending them across the internet, if you are just gonna move them via a USB key then don't sweat it.)

4. Move these files to your new server

   administration.config
   applicationHost.config
   configEncKey.key 
   

5. On the new server, go back to the “Shared Configuration” section and check “Enable shared configuration.” Enter the location in physical path to these files and apply them.

6. It should prompt for the encryption password(if you set it) and reset IIS.

BAM! Go have a beer!

If you go to chrome://extensions/, you can just toggle each extension one at a time and see which one is actually triggering the issue.

Once you toggle the extension off, refresh the page where you are seeing the error and wiggle the mouse around, or click. Mouse actions are the things that are throwing errors.

So I was able to pinpoint which extension was actually causing the issue and disable it.

You may use EasyMock.makeThreadSafe to make testing instance threadsafe

Answering the question "given two lists, find all possible permutations of pairs of one item from each list" and using basic Python functionality (i.e., without itertools) and, hence, making it easy to replicate for other programming languages:

def rec(a, b, ll, size):
    ret = []
    for i,e in enumerate(a):
        for j,f in enumerate(b):
            l = [e+f]
            new_l = rec(a[i+1:], b[:j]+b[j+1:], ll, size)
            if not new_l:
                ret.append(l)
            for k in new_l:
                l_k = l + k
                ret.append(l_k)
                if len(l_k) == size:
                    ll.append(l_k)
    return ret

a = ['a','b','c']
b = ['1','2']
ll = []
rec(a,b,ll, min(len(a),len(b)))
print(ll)

Returns

[['a1', 'b2'], ['a1', 'c2'], ['a2', 'b1'], ['a2', 'c1'], ['b1', 'c2'], ['b2', 'c1']]

Use List.AddRange(collection As IEnumerable(Of T)) method.

It allows you to append at the end of your list another collection/list.

Example:

List<string> initialList = new List<string>();
// Put whatever you want in the initial list
List<string> listToAdd = new List<string>();
// Put whatever you want in the second list
initialList.AddRange(listToAdd);

If you want to ensure they all get called, use super at all levels.

You should first check if Session["emp_num"] exists in the session.

You can ask the session object if its indexer has the emp_num value or use string.IsNullOrEmpty(Session["emp_num"])

Since JSF 2.3 all the bean scopes defined in package javax.faces.bean package have been deprecated to align the scopes with CDI. Moreover they're only applicable if your bean is using @ManagedBean annotation. If you are using JSF versions below 2.3 refer to the legacy answer at the end.

From JSF 2.3 here are scopes that can be used on JSF Backing Beans:

1. @javax.enterprise.context.ApplicationScoped: The application scope persists for the entire duration of the web application. That scope is shared among all requests and all sessions. This is useful when you have data for whole application.

2. @javax.enterprise.context.SessionScoped: The session scope persists from the time that a session is established until session termination. The session context is shared between all requests that occur in the same HTTP session. This is useful when you wont to save data for a specific client for a particular session.

3. @javax.enterprise.context.ConversationScoped: The conversation scope persists as log as the bean lives. The scope provides 2 methods: Conversation.begin() and Conversation.end(). These methods should called explicitly, either to start or end the life of a bean.

4. @javax.enterprise.context.RequestScoped: The request scope is short-lived. It starts when an HTTP request is submitted and ends after the response is sent back to the client. If you place a managed bean into request scope, a new instance is created with each request. It is worth considering request scope if you are concerned about the cost of session scope storage.

5. @javax.faces.flow.FlowScoped: The Flow scope persists as long as the Flow lives. A flow may be defined as a contained set of pages (or views) that define a unit of work. Flow scoped been is active as long as user navigates with in the Flow.

6. @javax.faces.view.ViewScoped: A bean in view scope persists while the same JSF page is redisplayed. As soon as the user navigates to a different page, the bean goes out of scope.

The following legacy answer applies JSF version before 2.3

As of JSF 2.x there are 4 Bean Scopes:

• @SessionScoped
• @RequestScoped
• @ApplicationScoped
• @ViewScoped

Session Scope: The session scope persists from the time that a session is established until session termination. A session terminates if the web application invokes the invalidate method on the HttpSession object, or if it times out.

RequestScope: The request scope is short-lived. It starts when an HTTP request is submitted and ends after the response is sent back to the client. If you place a managed bean into request scope, a new instance is created with each request. It is worth considering request scope if you are concerned about the cost of session scope storage.

ApplicationScope: The application scope persists for the entire duration of the web application. That scope is shared among all requests and all sessions. You place managed beans into the application scope if a single bean should be shared among all instances of a web application. The bean is constructed when it is first requested by any user of the application, and it stays alive until the web application is removed from the application server.

ViewScope: View scope was added in JSF 2.0. A bean in view scope persists while the same JSF page is redisplayed. (The JSF specification uses the term view for a JSF page.) As soon as the user navigates to a different page, the bean goes out of scope.

Choose the scope you based on your requirement.

The approach that I've taken has evolved since Java 1.0 to provide readability and maintain reasonable options for backward-compatibility with older Java versions, while also providing method signatures that are drop-in replacements for those from apache commons-lang. For performance reasons, I can see some possible objections to the use of Arrays.asList but I prefer helper methods that have sensible defaults without duplicating the one method that performs the actual work. This approach provides appropriate entry points to a reliable method that does not require array/list conversions prior to calling.

Possible variations for Java version compatibility include substituting StringBuffer (Java 1.0) for StringBuilder (Java 1.5), switching out the Java 1.5 iterator and removing the generic wildcard (Java 1.5) from the Collection (Java 1.2). If you want to take backward compatibility a step or two further, delete the methods that use Collection and move the logic into the array-based method.

public static String join(String[] values)
{
    return join(values, ',');
}

public static String join(String[] values, char delimiter)
{
    return join(Arrays.asList(values), String.valueOf(delimiter));
}

// To match Apache commons-lang: StringUtils.join(values, delimiter)
public static String join(String[] values, String delimiter)
{
    return join(Arrays.asList(values), delimiter);
}

public static String join(Collection<?> values)
{
    return join(values, ',');
}

public static String join(Collection<?> values, char delimiter)
{
    return join(values, String.valueOf(delimiter));
}

public static String join(Collection<?> values, String delimiter)
{
    if (values == null)
    {
        return new String();
    }

    StringBuffer strbuf = new StringBuffer();

    boolean first = true;

    for (Object value : values)
    {
        if (!first) { strbuf.append(delimiter); } else { first = false; }
        strbuf.append(value.toString());
    }

    return strbuf.toString();
}

If you have a huge number of objects, this can (at times) be much faster:

try:
    orgs[0]
    # If you get here, it exists...
except IndexError:
    # Doesn't exist!

On a project I'm working on with a huge database, not orgs is 400+ ms and orgs.count() is 250ms. In my most common use cases (those where there are results), this technique often gets that down to under 20ms. (One case I found, it was 6.)

Could be much longer, of course, depending on how far the database has to look to find a result. Or even faster, if it finds one quickly; YMMV.

EDIT: This will often be slower than orgs.count() if the result isn't found, particularly if the condition you're filtering on is a rare one; as a result, it's particularly useful in view functions where you need to make sure the view exists or throw Http404. (Where, one would hope, people are asking for URLs that exist more often than not.)

The first allocates an object with automatic storage duration, which means it will be destructed automatically upon exit from the scope in which it is defined.

The second allocated an object with dynamic storage duration, which means it will not be destructed until you explicitly use delete to do so.

An update

Now on windows no need to run react-native start. The packager will run automatically.

DateTime xmas = new DateTime(2009, 12, 25);
double daysUntilChristmas = xmas.Subtract(DateTime.Today).TotalDays;

I disagree with yydi answer saying:

If Android decides to recreate your Fragment later, it's going to call the no-argument constructor of your fragment. So overloading the constructor is not a solution.

I think it is a solution and a good one, this is exactly the reason it been developed by Java core language.

Its true that Android system can destroy and recreate your Fragment. So you can do this:

public MyFragment() {
//  An empty constructor for Android System to use, otherwise exception may occur.
}

public MyFragment(int someInt) {
    Bundle args = new Bundle();
    args.putInt("someInt", someInt);
    setArguments(args);
}

It will allow you to pull someInt from getArguments() latter on, even if the Fragment been recreated by the system. This is more elegant solution than static constructor.

For my opinion static constructors are useless and should not be used. Also they will limit you if in the future you would like to extend this Fragment and add more functionality to the constructor. With static constructor you can't do this.

Update:

Android added inspection that flag all non-default constructors with an error.
I recommend to disable it, for the reasons mentioned above.

May I suggest a php+css solution I used on my site? It's simple and no js problems :)

url to page: <a href="page.php?tab=menu1">link to menu1</a>

<?
$tab = $_GET['tab'];
?>
<ul class="nav nav-tabs">
  <li class="<? if ($tab=='menu1' OR $tab=='menu2') 
{
echo "";
} 
else {
echo "active";
}
?>"><a data-toggle="tab" href="#home">Prodotti</a></li>
  <li class="<? if ($tab=='menu1') 
{
echo "active";
} 
?>"><a data-toggle="tab" href="#menu1">News</a></li>
  <li class="<? if ($tab=='menu2') 
{
echo "active";
} 
?>"><a data-toggle="tab" href="#menu2">Gallery</a></li>
</ul>

<div class="tab-content">

Open "SQL Shell (psql)" from your Applications (Mac).

Click enter for the default settings. Enter the password when prompted.

*) Type \? for help

*) Type \conninfo to see which user you are connected as.

*) Type \l to see the list of Databases.

*) Connect to a database by \c <Name of DB>, for example \c GeneDB1

You should see the key prompt change to the new DB, like so:

*) Now that you're in a given DB, you want to know the Schemas for that DB. The best command to do this is \dn.

Other commands that also work (but not as good) are select schema_name from information_schema.schemata; and select nspname from pg_catalog.pg_namespace;:

-) Now that you have the Schemas, you want to know the tables in those Schemas. For that, you can use the dt command. For example \dt "GeneSchema1".*

*) Now you can do your queries. For example:

*) Here is what the above DB, Schema, and Tables look like in pgAdmin:

The problem with the css3 scroll bars is that, interaction can only be performed on the content. we can't interact with the scroll bar on touch devices.

$('select').on('change', function (e) {
    var optionSelected = $("option:selected", this);
    var valueSelected = this.value;
    ....
});

Had same issue, however I'm using Macbook Pro (2016) which has USB-c only and I forgot my adapter at home.

Since unable to run adb at all on my development machine, I found a different approach.

Connecting phone with USB cable to another computer (in same WiFi) and enable run adb tcpip from there.

Master-machine : computer where development goes on, with only USB-C connectors

Slave-machine: another computer with USB and in same WiFi

Steps:

1. Connect the phone to a different computer (slave-machine)
2. Run adb usb && adb tcpip 5555 from there

3. On master machine

   deko$: adb devices
   List of devices attached
   
   deko$: adb connect 10.0.20.153:5555
   connected to 10.0.20.153:5555
   

4. Now Android Studio or Xamarin can install and run app on the phone

Sidenote:

I also tested Bluetooth tethering from the Phone to Master-machine and successfully connected to phone. Both Android Studio and Xamarin worked well, however the upload process, from Xamarin was taking long time. But it works.

For windows users, there is an easy fix. Download whl files from:

https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4

run from anaconda prompt pip install PyQt4-4.11.4-cp37-cp37m-win_amd64.whl

The python 2.5 documentation explains it well.

Tuples and lists are compared lexicographically using comparison of corresponding elements. This means that to compare equal, each element must compare equal and the two sequences must be of the same type and have the same length.

If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is ordered first (for example, [1,2] < [1,2,3]).

Unfortunately that page seems to have disappeared in the documentation for more recent versions.

In my experience using the 'switch' statement is the standard way to handle multiple possible states. Although I am surpirsed that you are passing in a transition value to the per-state processing. I thought the whole point of a state machine was that each state performed a single action. Then the next action/input determines which new state to transition into. So I would have expected each state processing function to immediately perform whatever is fixed for entering state and then afterwards decide if transition is needed to another state.

One user control can't be applied to it ownself. So open another winform and the one will appear in the toolbox.

Try this:

1. php artisan cache:clear
2. php artisan config:clear
3. php artisan view:clear

You should have if row[2] != "0". Otherwise it's not checking to see if the string value is equal to 0.

There is the easy way

HTML:

<input type="checkbox" name="test[]" />x
<input type="checkbox" name="test[]"  />y
<input type="checkbox" name="test[]" />z
<button type="button" id="submit">Submit</button>

JQUERY:

$("#submit").on("click",function(){
    if (($("input[name*='test']:checked").length)<=0) {
        alert("You must check at least 1 box");
    }
    return true;
});

For this you not need any plugin. Enjoy;)

Note that all of the example that use

<repository>...</respository> 

require outer

<repositories>...</repositories> 

enclosing tags. It's not clear from some of the examples.

For those who found this page looking for a way to do this in IAR, try this:

      message #177-D: variable "x" was declared but never referenced.
      Instead, we have suppressed this warning throughout the entire 
      scope of foo1(). 
   */
   int x;
}

One option, that looks like it makes two functions run at the same
time, is using the threading module (example in this answer).

However, it has a small delay, as an Official Python Documentation
page describes. A better module to try using is multiprocessing.

Also, there's other Python modules that can be used for asynchronous execution (two pieces of code working at the same time). For some information about them and help to choose one, you can read this Stack Overflow question.

Comment from another user about the threading module

He might want to know that because of the Global Interpreter Lock
they will not execute at the exact same time even if the machine in
question has multiple CPUs. wiki.python.org/moin/GlobalInterpreterLock

– Jonas Elfström Jun 2 '10 at 11:39

Quote from the Documentation about threading module not working

CPython implementation detail: In CPython, due to the Global Interpreter
Lock, only one thread can execute Python code at once (even though
certain performance-oriented libraries might overcome this limitation).

If you want your application to make better use of the computational resources of multi-core machines, you are advised to use multiprocessing or concurrent.futures.ProcessPoolExecutor.
However, threading is still an appropriate model if you
want to run multiple I/O-bound tasks simultaneously.

I've found a solution for self-developed classes (or such you have access to).

Place the following computed property within your objects class definition:

var className: String? {
    return __FILE__.lastPathComponent.stringByDeletingPathExtension
}

Now you can simply call the class name on your object like so:

myObject.className

Please note that this will only work if your class definition is made within a file that is named exactly like the class you want the name of.

As this is commonly the case the above answer should do it for most cases. But in some special cases you might need to figure out a different solution.

If you need the class name within the class (file) itself you can simply use this line:

let className = __FILE__.lastPathComponent.stringByDeletingPathExtension

Maybe this method helps some people out there.

filter_by is used for simple queries on the column names using regular kwargs, like

db.users.filter_by(name='Joe')

The same can be accomplished with filter, not using kwargs, but instead using the '==' equality operator, which has been overloaded on the db.users.name object:

db.users.filter(db.users.name=='Joe')

You can also write more powerful queries using filter, such as expressions like:

db.users.filter(or_(db.users.name=='Ryan', db.users.country=='England'))

This trick only requires one command: type net session into the command prompt.

If you are NOT an admin, you get an access is denied message.

System error 5 has occurred.

Access is denied.

If you ARE an admin, you get a different message, the most common being:

There are no entries in the list.

From MS Technet:

Used without parameters, net session displays information about all sessions with the local computer.

Change table's default charset:

ALTER TABLE etape_prospection
  CHARACTER SET utf8,
  COLLATE utf8_general_ci;

To change string column charset exceute this query:

ALTER TABLE etape_prospection
  CHANGE COLUMN etape_prosp_comment etape_prosp_comment TEXT CHARACTER SET utf8 COLLATE utf8_general_ci;

I ran to a similar problem and that was just because of the extra spaces:

<uses-permission android:name="android.permission.INTERNET "/>

which when removed works fine:

<uses-permission android:name="android.permission.INTERNET"/>

No need to pass anything in. The function used for addEventListener will automatically have this bound to the current element. Simply use this in your function:

productLineSelect.addEventListener('change', getSelection, false);

function getSelection() {
    var value = this.options[this.selectedIndex].value;
    alert(value);
}

Here's the fiddle: http://jsfiddle.net/dJ4Wm/

If you want to pass arbitrary data to the function, wrap it in your own anonymous function call:

productLineSelect.addEventListener('change', function() {
    foo('bar');
}, false);

function foo(message) {
    alert(message);
}

Here's the fiddle: http://jsfiddle.net/t4Gun/

If you want to set the value of this manually, you can use the call method to call the function:

var self = this;
productLineSelect.addEventListener('change', function() {
    getSelection.call(self);
    // This'll set the `this` value inside of `getSelection` to `self`
}, false);

function getSelection() {
    var value = this.options[this.selectedIndex].value;
    alert(value);
}

by default you would need to use the postgres user:

sudo -u postgres psql postgres

This is the dumbest answer to this question, but check the status of GitHub. This one got me :)

As far as i understand fr is the object of your FileReadExample class. So it is obvious it will not have any method like fr.readLine() if you dont create one yourself.

secondly, i think a correct constructor of the BufferedReader class will help you do your task.

String str;
BufferedReader buffread = new BufferedReader(new FileReader(new File("file.dat")));
str = buffread.readLine();
.
.
buffread.close();

this should help you.

Try this, perhaps it works ;)

.factory('authInterceptor', function($location, $q, $window) {


return {
    request: function(config) {
      config.headers = config.headers || {};

      config.headers.Authorization = 'xxxx-xxxx';

      return config;
    }
  };
})

.config(function($httpProvider) {
  $httpProvider.interceptors.push('authInterceptor');
})

And make sure your back end works too, try this. I'm using RESTful CodeIgniter.

class App extends REST_Controller {
    var $authorization = null;

    public function __construct()
    {
        parent::__construct();
        header('Access-Control-Allow-Origin: *');
        header("Access-Control-Allow-Headers: X-API-KEY, Origin, X-Requested-With, Content-Type, Accept, Access-Control-Request-Method, Authorization");
        header("Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE");
        if ( "OPTIONS" === $_SERVER['REQUEST_METHOD'] ) {
            die();
        }

        if(!$this->input->get_request_header('Authorization')){
            $this->response(null, 400);    
        }

        $this->authorization = $this->input->get_request_header('Authorization');
    }

}

As others have suggested, the best way to do this is to use a join instead of variable assignment. Re-writing your query to use a join (and using the explicit join syntax instead of the implicit join, which was also suggested--and is the best practice), you would get something like this:

select  
  OrderDetails.Sku,
  OrderDetails.mf_item_number,
  OrderDetails.Qty,
  OrderDetails.Price,
  Supplier.SupplierId, 
  Supplier.SupplierName,
  Supplier.DropShipFees, 
  Supplier_Item.Price as cost
from 
  OrderDetails
join Supplier on OrderDetails.Mfr_ID = Supplier.SupplierId
join Group_Master on Group_Master.Sku = OrderDetails.Sku 
join Supplier_Item on 
  Supplier_Item.SKU=OrderDetails.Sku and Supplier_Item.SupplierId=Supplier.SupplierID 
where 
  invoiceid='339740'

2) Here a great tip from another user (Thxs Bill Dandreta): Sometimes

kill -9 <pid>

will not kill a process. Run

ps -xal

the 4th field is the parent process, kill all of a zombie's parents and the zombie dies!

Example

4 0 18581 31706 17 0 2664 1236 wait S ? 0:00 sh -c /usr/bin/gcc -fomit-frame-pointer -O -mfpmat
4 0 18582 18581 17 0 2064 828 wait S ? 0:00 /usr/i686-pc-linux-gnu/gcc-bin/3.3.6/gcc -fomit-fr
4 0 18583 18582 21 0 6684 3100 - R ? 0:00 /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/cc1 -quie

18581, 18582, 18583 are zombies -

kill -9 18581 18582 18583

has no effect.

kill -9 31706

removes the zombies.

Yes, it is a hash mapping or hash table. You can read a description of python's dict implementation, as written by Tim Peters, here.

That's why you can't use something 'not hashable' as a dict key, like a list:

>>> a = {}
>>> b = ['some', 'list']
>>> hash(b)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable
>>> a[b] = 'some'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable

You can read more about hash tables or check how it has been implemented in python and why it is implemented that way.

Python is a dynamic, strongly typed, object oriented, multipurpose programming language, designed to be quick (to learn, to use, and to understand), and to enforce a clean and uniform syntax.

1. Python is dynamically typed: it means that you don't declare a type (e.g. 'integer') for a variable name, and then assign something of that type (and only that type). Instead, you have variable names, and you bind them to entities whose type stays with the entity itself. a = 5 makes the variable name a to refer to the integer 5. Later, a = "hello" makes the variable name a to refer to a string containing "hello". Static typed languages would have you declare int a and then a = 5, but assigning a = "hello" would have been a compile time error. On one hand, this makes everything more unpredictable (you don't know what a refers to). On the other hand, it makes very easy to achieve some results a static typed languages makes very difficult.
2. Python is strongly typed. It means that if a = "5" (the string whose value is '5') will remain a string, and never coerced to a number if the context requires so. Every type conversion in python must be done explicitly. This is different from, for example, Perl or Javascript, where you have weak typing, and can write things like "hello" + 5 to get "hello5".
3. Python is object oriented, with class-based inheritance. Everything is an object (including classes, functions, modules, etc), in the sense that they can be passed around as arguments, have methods and attributes, and so on.
4. Python is multipurpose: it is not specialised to a specific target of users (like R for statistics, or PHP for web programming). It is extended through modules and libraries, that hook very easily into the C programming language.
5. Python enforces correct indentation of the code by making the indentation part of the syntax. There are no control braces in Python. Blocks of code are identified by the level of indentation. Although a big turn off for many programmers not used to this, it is precious as it gives a very uniform style and results in code that is visually pleasant to read.
6. The code is compiled into byte code and then executed in a virtual machine. This means that precompiled code is portable between platforms.

Python can be used for any programming task, from GUI programming to web programming with everything else in between. It's quite efficient, as much of its activity is done at the C level. Python is just a layer on top of C. There are libraries for everything you can think of: game programming and openGL, GUI interfaces, web frameworks, semantic web, scientific computing...

The problem is that buttonClickedEvent is a member function and you need a pointer to member in order to invoke it.

Try this:

void (MyClass::*func)(int);
func = &MyClass::buttonClickedEvent;

And then when you invoke it, you need an object of type MyClass to do so, for example this:

(this->*func)(<argument>);

Obj-C has much more dynamic capabilities in the language itself, whereas C++ is more focused on compile-time capabilities with some dynamic capabilities.

In, C++ parametric polymorphism is checked at compile-time, whereas in Obj-C, parametric polymorphism is achieved through dynamic dispatch and is not checked at compile-time.

Obj-C is very dynamic in nature. You can add methods to a class during run-time. Also, it has introspection at run-time to look at classes. In C++, the definition of class can't change, and all introspection must be done at compile-time. Although, the dynamic nature of Obj-C could be achieved in C++ using a map of functions(or something like that), it is still more verbose than in Obj-C.

In C++, there is a lot more checks that can be done at compile time. For example, using a variant type(like a union) the compiler can enforce that all cases are written or handled. So you don't forget about handling the edge cases of a problem. However, all these checks come at a price when compiling. Obj-C is much faster at compiling than C++.

This answer assumes you understand implementing the perfect algorithm for P1 and discusses how to achieve a win in conditions against ordinary human players, who will make some mistakes more commonly than others.

The game of course should end in a draw if both players play optimally. At a human level, P1 playing in a corner produces wins far more often. For whatever psychological reason, P2 is baited into thinking that playing in the center is not that important, which is unfortunate for them, since it's the only response that does not create a winning game for P1.

If P2 does correctly block in the center, P1 should play the opposite corner, because again, for whatever psychological reason, P2 will prefer the symmetry of playing a corner, which again produces a losing board for them.

For any move P1 may make for the starting move, there is a move P2 may make that will create a win for P1 if both players play optimally thereafter. In that sense P1 may play wherever. The edge moves are weakest in the sense that the largest fraction of possible responses to this move produce a draw, but there are still responses that will create a win for P1.

Empirically (more precisely, anecdotally) the best P1 starting moves seem to be first corner, second center, and last edge.

The next challenge you can add, in person or via a GUI, is not to display the board. A human can definitely remember all the state but the added challenge leads to a preference for symmetric boards, which take less effort to remember, leading to the mistake I outlined in the first branch.

I'm a lot of fun at parties, I know.

To convert a const char* to char* you could create a function like this :

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

char* unconstchar(const char* s) {
    if(!s)
      return NULL;
    int i;
    char* res = NULL;
    res = (char*) malloc(strlen(s)+1);
    if(!res){
        fprintf(stderr, "Memory Allocation Failed! Exiting...\n");
        exit(EXIT_FAILURE);
    } else{
        for (i = 0; s[i] != '\0'; i++) {
            res[i] = s[i];
        }
        res[i] = '\0';
        return res;
    }
}

int main() {
    const char* s = "this is bikash";
    char* p = unconstchar(s);
    printf("%s",p);
    free(p);
}

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

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

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

Ex netstat -anp | find ":8080"

SELECT * FROM
DocumentStatusLogs JOIN (
  SELECT DocumentID, MAX(DateCreated) DateCreated
  FROM DocumentStatusLogs
  GROUP BY DocumentID
  ) max_date USING (DocumentID, DateCreated)

What database server? This code doesn't work on all of them.

Regarding the second half of your question, it seems reasonable to me to include the status as a column. You can leave DocumentStatusLogs as a log, but still store the latest info in the main table.

BTW, if you already have the DateCreated column in the Documents table you can just join DocumentStatusLogs using that (as long as DateCreated is unique in DocumentStatusLogs).

Edit: MsSQL does not support USING, so change it to:

ON DocumentStatusLogs.DocumentID = max_date.DocumentID AND DocumentStatusLogs.DateCreated = max_date.DateCreated

check this:

<div id="benefits" style="display:none;">some input in here plus the close button
       <div id="upbutton"><a onclick="close(); return false;"></a></div>

Like this:

>>> structTime = time.localtime()
>>> datetime.datetime(*structTime[:6])
datetime.datetime(2009, 11, 8, 20, 32, 35)

A lot of good answers explaining what the assert keyword does, but few answering the real question, "when should the assert keyword be used in real life?"

The answer: almost never.

Assertions, as a concept, are wonderful. Good code has lots of if (...) throw ... statements (and their relatives like Objects.requireNonNull and Math.addExact). However, certain design decisions have greatly limited the utility of the assert keyword itself.

The driving idea behind the assert keyword is premature optimization, and the main feature is being able to easily turn off all checks. In fact, the assert checks are turned off by default.

However, it is critically important that invariant checks continue to be done in production. This is because perfect test coverage is impossible, and all production code will have bugs which assertions should help to diagnose and mitigate.

Therefore, the use of if (...) throw ... should be preferred, just as it is required for checking parameter values of public methods and for throwing IllegalArgumentException.

Occasionally, one might be tempted to write an invariant check that does take an undesirably long time to process (and is called often enough for it to matter). However, such checks will slow down testing which is also undesirable. Such time-consuming checks are usually written as unit tests. Nevertheless, it may sometimes make sense to use assert for this reason.

Do not use assert simply because it is cleaner and prettier than if (...) throw ... (and I say that with great pain, because I like clean and pretty). If you just cannot help yourself, and can control how your application is launched, then feel free to use assert but always enable assertions in production. Admittedly, this is what I tend to do. I am pushing for a lombok annotation that will cause assert to act more like if (...) throw .... Vote for it here.

(Rant: the JVM devs were a bunch of awful, prematurely optimizing coders. That is why you hear about so many security issues in the Java plugin and JVM. They refused to include basic checks and assertions in production code, and we are continuing to pay the price.)

use "mysql_insert_id()". mysql_insert_id() acts on the last performed query, be sure to call mysql_insert_id() immediately after the query that generates the value.

Below are the example of use:

<?php
    $link = mysql_connect('localhost', 'username', 'password');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
mysql_select_db('mydb');

mysql_query("INSERT INTO mytable  VALUES('','value')");
printf("Last inserted record has id %d\n", mysql_insert_id());
    ?>

I hope above example is useful.

I try with several alternatives, but due my data records has repeated values, the ROW_NUMBER versions seems are not a choice for me. So here the query I used (a version with NTILE):

SELECT distinct
   CustomerId,
   (
       MAX(CASE WHEN Percent50_Asc=1 THEN TotalDue END) OVER (PARTITION BY CustomerId)  +
       MIN(CASE WHEN Percent50_desc=1 THEN TotalDue END) OVER (PARTITION BY CustomerId) 
   )/2 MEDIAN
FROM
(
   SELECT
      CustomerId,
      TotalDue,
     NTILE(2) OVER (
         PARTITION BY CustomerId
         ORDER BY TotalDue ASC) AS Percent50_Asc,
     NTILE(2) OVER (
         PARTITION BY CustomerId
         ORDER BY TotalDue DESC) AS Percent50_desc
   FROM Sales.SalesOrderHeader SOH
) x
ORDER BY CustomerId;

In my case, click event was propagating on child element. So, I had to put the following:

e.stopPropagation()

on click event:

 $(document).on("click", ".remove-discount-button", function (e) {
           e.stopPropagation();
           //some code
        });
 $(document).on("click", ".current-code", function () {
     $('.remove-discount-button').trigger("click");
 });

Here is the html code:

 <div class="current-code">                                      
      <input type="submit" name="removediscountcouponcode" value="

Passing the data:

Intent intent = new Intent(getApplicationContext(),YourActivity.class);
Bundle bundle = new Bundle();
i.putParcelableArrayListExtra("data", (ArrayList<? extends Parcelable>) dataList);
intent.putExtras(bundle);
startActivity(intent);

Retrieving the data:

Bundle bundle = getIntent().getExtras();
dataList2 = getIntent().getExtras().getParcelableArrayList("data");

After doing some search i got solution from android developer guide

PendingIntent contentIntent ;
Intent intent = new Intent(this,TestActivity.class);
intent.putExtra("extra","Test");
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);

stackBuilder.addParentStack(ArticleDetailedActivity.class);

contentIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);

To Get Intent extra value in Test Activity class you need to write following code :

 Intent intent = getIntent();
 String extra = intent.getStringExtra("extra") ;

I feel like properties are about letting you get the overhead of writing getters and setters only when you actually need them.

Java Programming culture strongly advise to never give access to properties, and instead, go through getters and setters, and only those which are actually needed. It's a bit verbose to always write these obvious pieces of code, and notice that 70% of the time they are never replaced by some non-trivial logic.

In Python, people actually care for that kind of overhead, so that you can embrace the following practice :

• Do not use getters and setters at first, when if they not needed
• Use @property to implement them without changing the syntax of the rest of your code.

Use .length to count number of characters, and $.trim() function to remove spaces, and replace(/ /g,'') to replace multiple spaces with just one. Here is an example:

   var str = "      Hel  lo       ";
   console.log(str.length); 
   console.log($.trim(str).length); 
   console.log(str.replace(/ /g,'').length); 

Output:

20
7
5

Other than John's answer, you could also make one of the variable float, and the result will yield float.

>>> 144 / 314.0

You can use a $ sign like:

OUTPUT=$(expression)

This is an old question, but none of the posted answers worked in my case, I found that in my case I had selects and updates on a table in my stored procedure, the same table had an update trigger which was being triggered and senging the procedure into an infinite loop. Once the bug was found the error went away.

 window.open('your_url', 'popup_name','height=' + screen.height + ',width=' + screen.width + ',resizable=yes,scrollbars=yes,toolbar=yes,menubar=yes,location=yes')

I do not think any of these answers are flexible enough for a large enterprise level application. I'm not a fan of overusing the ViewBag, but in this case, for flexibility, I'd make an exception. Here's what I'd do...

You should have a base controller on all of your controllers. Add your Layout data OnActionExecuting in your base controller (or OnActionExecuted if you want to defer that)...

public class BaseController : Controller
{
    protected override void OnActionExecuting(ActionExecutingContext     
        filterContext)
    {
        ViewBag.LayoutViewModel = MyLayoutViewModel;
    }
}

public class HomeController : BaseController
{
    public ActionResult Index()
    {
        return View(homeModel);
    }
}

Then in your _Layout.cshtml pull your ViewModel from the ViewBag...

@{
  LayoutViewModel model = (LayoutViewModel)ViewBag.LayoutViewModel;
}

<h1>@model.Title</h1>

Or...

<h1>@ViewBag.LayoutViewModel.Title</h1>

Doing this doesn't interfere with the coding for your page's controllers or view models.

That means a topic is appropriate. A queue means a message goes to one and only one possible subscriber. A topic goes to each and every subscriber.

The MemoryError exception that you are seeing is the direct result of running out of available RAM. This could be caused by either the 2GB per program limit imposed by Windows (32bit programs), or lack of available RAM on your computer. (This link is to a previous question).

You should be able to extend the 2GB by using 64bit copy of Python, provided you are using a 64bit copy of windows.

The IndexError would be caused because Python hit the MemoryError exception before calculating the entire array. Again this is a memory issue.

To get around this problem you could try to use a 64bit copy of Python or better still find a way to write you results to file. To this end look at numpy's memory mapped arrays.

You should be able to run you entire set of calculation into one of these arrays as the actual data will be written disk, and only a small portion of it held in memory.

window.location.pathname will get you the directory, as well as the page name. You could then use .substring() to get the directory:

var loc = window.location.pathname;
var dir = loc.substring(0, loc.lastIndexOf('/'));

Hope this helps!

Have you added this gem to your gemfile?

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'

move that gem out of assets group and then run bundle again, I hope that would help!

Union type is in my mind best option in this case:

interface Employee{
   id: number;
   name: string;
   salary: number | null;
}

// Both cases are valid
let employe1: Employee = { id: 1, name: 'John', salary: 100 };
let employe2: Employee = { id: 1, name: 'John', salary: null };

EDIT : For this to work as expected, you should enable the strictNullChecks in tsconfig.

Use which.min:

df <- data.frame(Name=c('A','B','C','D'), Amount=c(150,120,175,160))
df[which.min(df$Amount),]

> df[which.min(df$Amount),]
  Name Amount
2    B    120

I created an Interface and a <options> tag helper for this. So I didn't have to convert the IEnumerable<T> items into IEnumerable<SelectListItem> every time I have to populate the <select> control.

And I think it works beautifully...

The usage is something like:

<select asp-for="EmployeeId">
    <option value="">Please select...</option>
    <options asp-items="@Model.EmployeesList" />
</select>

And to make it work with the tag helper you have to implement that interface in your class:

public class Employee : IIntegerListItem
{
   public int Id { get; set; }
   public string FullName { get; set; }

   public int Value { return Id; }
   public string Text{ return FullName ; }
}

These are the needed codes:

The interface:

public interface IIntegerListItem
{
    int Value { get; }
    string Text { get; }
}

The <options> tag helper:

[HtmlTargetElement("options", Attributes = "asp-items")]
public class OptionsTagHelper : TagHelper
{
    public OptionsTagHelper(IHtmlGenerator generator)
    {
        Generator = generator;
    }

    [HtmlAttributeNotBound]
    public IHtmlGenerator Generator { get; set; }

    [HtmlAttributeName("asp-items")]
    public object Items { get; set; }

    public override void Process(TagHelperContext context, TagHelperOutput output)
    {
        output.SuppressOutput();
        // Is this <options /> element a child of a <select/> element the SelectTagHelper targeted?
        object formDataEntry;
        context.Items.TryGetValue(typeof(SelectTagHelper), out formDataEntry);

        var selectedValues = formDataEntry as ICollection<string>;
        var encodedValues = new HashSet<string>(StringComparer.OrdinalIgnoreCase);
        if (selectedValues != null && selectedValues.Count != 0)
        {
            foreach (var selectedValue in selectedValues)
            {
                encodedValues.Add(Generator.Encode(selectedValue));
            }
        }

        IEnumerable<SelectListItem> items = null;
        if (Items != null)
        {
            if (Items is IEnumerable)
            {
                var enumerable = Items as IEnumerable;
                if (Items is IEnumerable<SelectListItem>)
                    items = Items as IEnumerable<SelectListItem>;
                else if (Items is IEnumerable<IIntegerListItem>)
                    items = ((IEnumerable<IIntegerListItem>)Items).Select(x => new SelectListItem() { Selected = false, Value = ((IIntegerListItem)x).Value.ToString(), Text = ((IIntegerListItem)x).Text });
                else
                    throw new InvalidOperationException(string.Format("The {2} was unable to provide metadata about '{1}' expression value '{3}' for <options>.",
                        "<options>",
                        "ForAttributeName",
                        nameof(IModelMetadataProvider),
                        "For.Name"));
            }
            else
            {
                throw new InvalidOperationException("Invalid items for <options>");
            }

            foreach (var item in items)
            {
                bool selected = (selectedValues != null && selectedValues.Contains(item.Value)) || encodedValues.Contains(item.Value);
                var selectedAttr = selected ? "selected='selected'" : "";

                if (item.Value != null)
                    output.Content.AppendHtml($"<option value='{item.Value}' {selectedAttr}>{item.Text}</option>");
                else
                    output.Content.AppendHtml($"<option>{item.Text}</option>");
            }
        }
    }
}

There may be some typo but the aim is clear I think. I had to edit a little bit.

For me, eclipse was looking in the wrong place for the SDK Manager. To fix this I did

• Window/ Preferences/ Android/ SDK Location

NOTE: The SDK manager tells you what dir it is using near the top of the UI.

I had installed a new version of eclipse that has the ADT bundled up from the Android developer site, but when I opened eclipse it was looking at the old SDK.exe location.

$utfEncodedArray = array_map("utf8_encode", $inputArray );

Does the job and returns a serialized array with numeric keys (not an assoc).

You are producing a filtered list by using a list comprehension. i is still being bound to each and every element of that list, and the last element is still 'three', even if it was subsequently filtered out from the list being produced.

You should not use a list comprehension to pick out one element. Just use a for loop, and break to end it:

for elem in my_list:
    if elem == 'two':
        break

If you must have a one-liner (which would be counter to Python's philosophy, where readability matters), use the next() function and a generator expression:

i = next((elem for elem in my_list if elem == 'two'), None)

which will set i to None if there is no such matching element.

The above is not that useful a filter; your are essentially testing if the value 'two' is in the list. You can use in for that:

elem = 'two' if 'two' in my_list else None

Old question but I have a much better way of doing this. Rather than using rect() use polygon. This allows you to keep everything in plot without using points. Also you don't have to mess with par at all. If you want to keep things automated make the coordinates of polygon a function of your data.

plot.new()
polygon(c(-min(df[,1])^2,-min(df[,1])^2,max(df[,1])^2,max(df[,1])^2),c(-min(df[,2])^2,max(df[,2])^2,max(df[,2])^2,-min(df[,2])^2), col="grey")
par(new=T)
plot(df)

Easiest way would probably be with jQuery, as follows:

$(document).ready(function(){
  $("#_1234").attr("checked","checked");
})

This adds a new attribute "checked" (which in HTML does not need a value). Just remember to include the jQuery library:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

Expanding on a previous answer, this removes all new lines and saves the result to a new file (thanks to @tripleee):

tr -d '\n' < yourfile.txt > yourfile2.txt

Which is better than a "useless cat" (see comments):

cat file.txt | tr -d '\n' > file2.txt

Also useful for getting rid of new lines at the end of the file, e.g. created by using echo blah > file.txt.

A dangling pointer is one that has a value (not NULL) which refers to some memory which is not valid for the type of object you expect. For example if you set a pointer to an object then overwrote that memory with something else unrelated or freed the memory if it was dynamically allocated.

A memory leak is when you dynamically allocate memory from the heap but never free it, possibly because you lost all references to it.

They are related in that they are both situations relating to mismanaged pointers, especially regarding dynamically allocated memory. In one situation (dangling pointer) you have likely freed the memory but tried to reference it afterwards; in the other (memory leak), you have forgotten to free the memory entirely!

Simply update with a convert/cast to INT:

UPDATE YOUR_TABLE
SET YOUR_COLUMN = CAST(YOUR_COLUMN AS INT)
WHERE -- some condition is met if required

Or convert:

UPDATE YOUR_TABLE
SET YOUR_COLUMN = CONVERT(INT, YOUR_COLUMN)
WHERE -- some condition is met if required

To test you can do this:

SELECT YOUR_COLUMN AS CurrentValue,
       CAST(YOUR_COLUMN AS INT) AS NewValue
FROM YOUR_TABLE

One thing that got this working for me is to make sure that github.com is in ~jenkins/.ssh/known_hosts.

Backup your databases

docker exec -t your-db-container pg_dumpall -c -U postgres > dump_`date +%d-%m-%Y"_"%H_%M_%S`.sql

Restore your databases

cat your_dump.sql | docker exec -i your-db-container psql -U postgres

This function uses the current millisecond time to subtract the current week, and then subtracts one more week if the current date is on a monday (javascript counts from sunday).

function getMonday(fromDate) {
    // length of one day i milliseconds
  var dayLength = 24 * 60 * 60 * 1000;

  // Get the current date (without time)
    var currentDate = new Date(fromDate.getFullYear(), fromDate.getMonth(), fromDate.getDate());

  // Get the current date's millisecond for this week
  var currentWeekDayMillisecond = ((currentDate.getDay()) * dayLength);

  // subtract the current date with the current date's millisecond for this week
  var monday = new Date(currentDate.getTime() - currentWeekDayMillisecond + dayLength);

  if (monday > currentDate) {
    // It is sunday, so we need to go back further
    monday = new Date(monday.getTime() - (dayLength * 7));
  }

  return monday;
}

I have tested it when week spans over from one month to another (and also years), and it seems to work properly.

The main problem was that you were opening/closing files repeatedly inside your loop.

Try this approach:

with open('new.txt') as text_file, open('xyz.txt', 'w') as myfile:  
    for line in text_file:
        var1, var2 = line.split(",");
        myfile.write(var1+'\n')

We open both files at once and because we are using with they will be automatically closed when we are done (or an exception occurs). Previously your output file was repeatedly openend inside your loop.

We are also processing the file line-by-line, rather than reading all of it into memory at once (which can be a problem when you deal with really big files).

Note that write() doesn't append a newline ('\n') so you'll have to do that yourself if you need it (I replaced your writelines() with write() as you are writing a single item, not a list of items).

When opening a file for rread, the 'r' is optional since it's the default mode.

The above answers seem to resolve the issue. If it doesn't, then you may also try to update conda using the following command.

conda update conda

And then try to install numpy using

conda install numpy

I'm putting this in a new answer because no linebreaks / codeblocks in comments. I assume you want those nans to turn into a blank string? I couldn't find a nice way to do this, only do the ugly method:

s = pd.Series([1001.,1002.,None])
a = s.loc[s.isnull()].fillna('')
b = s.loc[s.notnull()].astype(int).astype(str)
result = pd.concat([a,b])

I've had a similar problem when building Clang from source (but not with sudo apt-get install. This might depend on the version of Ubuntu which you're running).

It might be worth checking if clang++ can find the correct locations of your C++ libraries:

Compare the results of g++ -v <filename.cpp> and clang++ -v <filename.cpp>, under "#include < ... > search starts here:".
