Check if you have set restrict outgoing SMTP to only some system users (root, MTA, mailman...). That restriction may prevent the spammers, but will redirect outgoing SMTP connections to the local mail server.

c# 7.0 lets you do this:

  var tupleList = new List<(int, string)>
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

If you don't need a List, but just an array, you can do:

  var tupleList = new(int, string)[]
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

And if you don't like "Item1" and "Item2", you can do:

  var tupleList = new List<(int Index, string Name)>
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

or for an array:

  var tupleList = new (int Index, string Name)[]
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

which lets you do: tupleList[0].Index and tupleList[0].Name

Framework 4.6.2 and below

You must install System.ValueTuple from the Nuget Package Manager.

Framework 4.7 and above

It is built into the framework. Do not install System.ValueTuple. In fact, remove it and delete it from the bin directory.

note: In real life, I wouldn't be able to choose between cow, chickens or airplane. I would be really torn.

and awk as well

awk 'NR!~/^(5|10|25)$/' file

The purpose of .iteritems() was to use less memory space by yielding one result at a time while looping. I am not sure why Python 3 version does not support iteritems()though it's been proved to be efficient than .items()

If you want to include a code that supports both the PY version 2 and 3,

try:
    iteritems
except NameError:
    iteritems = items

This can help if you deploy your project in some other system and you aren't sure about the PY version.

As you are looking for select permissions, I would suggest you to grant only select rather than all privileges. You can do this by:

GRANT SELECT ON <table> TO <role>;

Based on docker documentation: https://docs.docker.com/compose/compose-file/#/command

I simply put hostname: <string> in my docker-compose file.

E.g.:

[...]

lb01:
  hostname: at-lb01
  image: at-client-base:v1

[...]

and container lb01 picks up at-lb01 as hostname.

If you are using SQL Server 2005 or above use this:

SELECT *
  FROM (
                SELECT  ID, 
                        Email, 
                        ProductName, 
                        ProductModel,
                        ROW_NUMBER() OVER(PARTITION BY Email ORDER BY ID DESC) rn
                    FROM Products
              ) a
WHERE rn = 1

EDIT: Example using a where clause:

SELECT *
  FROM (
                SELECT  ID, 
                        Email, 
                        ProductName, 
                        ProductModel,
                        ROW_NUMBER() OVER(PARTITION BY Email ORDER BY ID DESC) rn
                    FROM Products
                   WHERE ProductModel = 2
                     AND ProductName LIKE 'CYBER%'

              ) a
WHERE rn = 1

An easy and elegant solution is to use _.isEqual, which performs a deep comparison:

var a = {};
var b = {};

a.prop1 = 2;
a.prop2 = { prop3: 2 };

b.prop1 = 2;
b.prop2 = { prop3: 3 };

console.log(_.isEqual(a, b)); // returns false if different

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.4/lodash.min.js"></script>

However, this solution doesn't show which property is different.

Maybe using pytest_collect_file() hook you can parse the content of a .txt o .yaml file where the tests are specify as you want, and return them to the pytest core.

A nice example is shown in the pytest documentation. I think what you are looking for.

If you want to use scrollWidth to get the "REAL" CONTENT WIDTH/HEIGHT (as content can be BIGGER than the css-defined width/height-Box) the scrollWidth/Height is very UNRELIABLE as some browser seem to "MOVE" the paddingRIGHT & paddingBOTTOM if the content is to big. They then place the paddings at the RIGHT/BOTTOM of the "too broad/high content" (see picture below).

==> Therefore to get the REAL CONTENT WIDTH in some browsers you have to substract BOTH paddings from the scrollwidth and in some browsers you only have to substract the LEFT Padding.

I found a solution for this and wanted to add this as a comment, but was not allowed. So I took the picture and made it a bit clearer in the regard of the "moved paddings" and the "unreliable scrollWidth". In the BLUE AREA you find my solution on how to get the "REAL" CONTENT WIDTH!

Hope this helps to make things even clearer!

sorted_by_second = sorted(data, key=lambda tup: tup[1])

or:

data.sort(key=lambda tup: tup[1])  # sorts in place

The script isn't even necessary, split(1) supports the wanted feature out of the box:
split -l 75 auth.log auth.log. The above command splits the file in chunks of 75 lines a piece, and outputs file on the form: auth.log.aa, auth.log.ab, ...

wc -l on the original file and output gives:

  321 auth.log
   75 auth.log.aa
   75 auth.log.ab
   75 auth.log.ac
   75 auth.log.ad
   21 auth.log.ae
  642 total

Try to temporarily modify request.js and harcode everywhere rejectUnauthorized = true, but it would be better to get the certificate extended as a long-term solution.

Look at SignalR Tests for the feature.

Test "SendToUser" takes automatically the user identity passed by using a regular owin authentication library.

The scenario is you have a user who has connected from multiple devices/browsers and you want to push a message to all his active connections.

I know this has an acceptable answer, but I ran into a situation where clientWidth didn't work, as iPhone (at least mine) returned 980, not 320, so I used window.screen.width. I was working on existing site, being made "responsive" and needed to force larger browsers to use a different meta-viewport.

Hope this helps someone, it may not be perfect, but it works in my testing on iOs and Android.

//sweet hack to set meta viewport for desktop sites squeezing down to mobile that are big and have a fixed width 
  //first see if they have window.screen.width avail
  (function() {
    if (window.screen.width)
    {
      var setViewport = {
        //smaller devices
        phone: 'width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no',
        //bigger ones, be sure to set width to the needed and likely hardcoded width of your site at large breakpoints  
        other: 'width=1045,user-scalable=yes',
        //current browser width
        widthDevice: window.screen.width,
        //your css breakpoint for mobile, etc. non-mobile first
        widthMin: 560,
        //add the tag based on above vars and environment 
        setMeta: function () {
          var params = (this.widthDevice <= this.widthMin) ? this.phone : this.other; 
          var head = document.getElementsByTagName("head")[0];
          var viewport = document.createElement('meta');
          viewport.setAttribute('name','viewport');
          viewport.setAttribute('content',params);
          head.appendChild(viewport);
        }
      }
      //call it 
      setViewport.setMeta();
    }
  }).call(this);

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my);
    getSupportActionBar().hide();
}

Try with: format(now(), "yyyy-MM-dd hh:mm:ss")

[I understand this is an old thread, just adding some more detail] The two answers by Mark and Jon Hanna sum up the differences, albeit it may interest some that

Guid.NewGuid()

Eventually calls CoCreateGuid (a COM call to Ole32) (reference here) and the actual work is done by UuidCreate.

Guid.Empty is meant to be used to check if a Guid contains all zeroes. This could also be done via comparing the value of the Guid in question with new Guid()

So, if you need a unique identifier, the answer is Guid.NewGuid()

try this:

var hasVScroll = document.body.scrollHeight > document.body.clientHeight;

This will only tell you if the vertical scrollHeight is bigger than the height of the viewable content, however. The hasVScroll variable will contain true or false.

If you need to do a more thorough check, add the following to the code above:

// Get the computed style of the body element
var cStyle = document.body.currentStyle||window.getComputedStyle(document.body, "");

// Check the overflow and overflowY properties for "auto" and "visible" values
hasVScroll = cStyle.overflow == "visible" 
             || cStyle.overflowY == "visible"
             || (hasVScroll && cStyle.overflow == "auto")
             || (hasVScroll && cStyle.overflowY == "auto");

Use something like this:

class Tree < T > : Dictionary < T, IList< Tree < T > > >  
{  
}  

It's ugly, but I think it will give you what you want. Too bad KeyValuePair is sealed.

Try ssh -t -t(or ssh -tt for short) to force pseudo-tty allocation even if stdin isn't a terminal.

See also: Terminating SSH session executed by bash script

From ssh manpage:

-T      Disable pseudo-tty allocation.

-t      Force pseudo-tty allocation.  This can be used to execute arbitrary 
        screen-based programs on a remote machine, which can be very useful,
        e.g. when implementing menu services.  Multiple -t options force tty
        allocation, even if ssh has no local tty.

Use this code:

byte[] decodedString = Base64.decode(Base64String.getBytes(), Base64.DEFAULT);

Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);

You have done it backwards, it should be:

amount = invest(amount,top_company(5,year,year+1),year)

I've used mingw on Linux to make Windows executables in C, I suspect C++ would work as well.

I have a project, ELLCC, that packages clang and other things as a cross compiler tool chain. I use it to compile clang (C++), binutils, and GDB for Windows. Follow the download link at ellcc.org for pre-compiled binaries for several Linux hosts.

You have to install the appropriate plug-in first (i.e., XML, C#, etc.).

Formatting won't become available until you've installed the relevant plugin, and saved the file with an appropriate extension.

(current / maximum) * 100. In your case, (2 / 10) * 100.

...5+ years later, I strongly suggest using date-fns instead

import endOfDayfrom 'date-fns/endOfDay'
import startOfDay from 'date-fns/startOfDay'

MyModel.find({
  createdAt: {
    $gte: startOfDay(new Date()),
    $lte: endOfDay(new Date())
  }
})

For those of us using Moment.js

const moment = require('moment')

const today = moment().startOf('day')

MyModel.find({
  createdAt: {
    $gte: today.toDate(),
    $lte: moment(today).endOf('day').toDate()
  }
})

Important: all moments are mutable!

tomorrow = today.add(1, 'days') does not work since it also mutates today. Calling moment(today) solves that problem by implicitly cloning today.

You may check service status of MS SQL Server 2014. In Windows 7 you can do that by:

1. Go to search and Type "SQL Server 2014 Configuration Manager
2. Then click on "SQL Server Service" on left menu
3. Check the instance of SQL Server service status if it is stopped or running
4. If it has stopped, please change the status to running and log in to SQL Server Management Studio 2014

def add(x, y):
    return x+y

That way it can then become a variable.

sum = add(3, 5)

print(sum)

But if the 'add' function print the output 'sum' would then be None as action would have already taken place after it being assigned.

Another argument often used against singletons is their testability problems. Singletons are not easily mockable for testing purposes. If this turns out to be a problem, I like to make the following slight modification:

public class SingletonImpl {

    private static SingletonImpl instance;

    public static SingletonImpl getInstance() {
        if (instance == null) {
            instance = new SingletonImpl();
        }
        return instance;
    }

    public static void setInstance(SingletonImpl impl) {
        instance = impl;
    }

    public void a() {
        System.out.println("Default Method");
    }
}

The added setInstance method allows setting a mockup implementation of the singleton class during testing:

public class SingletonMock extends SingletonImpl {

    @Override
    public void a() {
        System.out.println("Mock Method");
    }

}

This also works with early initialization approaches:

public class SingletonImpl {

    private static final SingletonImpl instance = new SingletonImpl();

    private static SingletonImpl alt;

    public static void setInstance(SingletonImpl inst) {
        alt = inst;
    }

    public static SingletonImpl getInstance() {
        if (alt != null) {
            return alt;
        }
        return instance;
    }

    public void a() {
        System.out.println("Default Method");
    }
}

public class SingletonMock extends SingletonImpl {

    @Override
    public void a() {
        System.out.println("Mock Method");
    }

}

This has the drawback of exposing this functionality to the normal application too. Other developers working on that code could be tempted to use the ´setInstance´ method to alter a specific function and thus changing the whole application behaviour, and therefore this method should contain at least a good warning in its javadoc.

Still, for the possibility of mockup-testing (when needed), this code exposure may be an acceptable price to pay.

This was asked a long time ago but this may still help someone:

MongoDB profiler logs all the queries in the capped collection system.profile. See this: database profiler

1. Start mongod instance with --profile=2 option that enables logging all queries OR if mongod instances is already running, from mongoshell, run db.setProfilingLevel(2) after selecting database. (it can be verified by db.getProfilingLevel(), which should return 2)
2. After this, I have created a script which utilises mongodb's tailable cursor to tail this system.profile collection and write the entries in a file. To view the logs I just need to tail it:tail -f ../logs/mongologs.txt. This script can be started in background and it will log all the operation on the db in the file.

My code for tailable cursor for the system.profile collection is in nodejs; it logs all the operations along with queries happening in every collection of MyDb:

const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');
const fs = require('fs');
const file = '../logs/mongologs'
// Connection URL
const url = 'mongodb://localhost:27017';

// Database Name
const dbName = 'MyDb';
//Mongodb connection

MongoClient.connect(url, function (err, client) {
   assert.equal(null, err);
   const db = client.db(dbName);
   listen(db, {})
});

function listen(db, conditions) {
var filter = { ns: { $ne: 'MyDb.system.profile' } }; //filter for query
//e.g. if we need to log only insert queries, use {op:'insert'}
//e.g. if we need to log operation on only 'MyCollection' collection, use {ns: 'MyDb.MyCollection'}
//we can give a lot of filters, print and check the 'document' variable below

// set MongoDB cursor options
var cursorOptions = {
    tailable: true,
    awaitdata: true,
    numberOfRetries: -1
};

// create stream and listen
var stream = db.collection('system.profile').find(filter, cursorOptions).stream();

// call the callback
stream.on('data', function (document) {
    //this will run on every operation/query done on our database
    //print 'document' to check the keys based on which we can filter
    //delete data which we dont need in our log file

    delete document.execStats;
    delete document.keysExamined;
    //-----
    //-----

    //append the log generated in our log file which can be tailed from command line
    fs.appendFile(file, JSON.stringify(document) + '\n', function (err) {
        if (err) (console.log('err'))
    })

});

}

For tailable cursor in python using pymongo, refer the following code which filters for MyCollection and only insert operation:

import pymongo
import time
client = pymongo.MongoClient()
oplog = client.MyDb.system.profile
first = oplog.find().sort('$natural', pymongo.ASCENDING).limit(-1).next()

ts = first['ts']
while True:
    cursor = oplog.find({'ts': {'$gt': ts}, 'ns': 'MyDb.MyCollection', 'op': 'insert'},
                        cursor_type=pymongo.CursorType.TAILABLE_AWAIT)
    while cursor.alive:
        for doc in cursor:
            ts = doc['ts']
            print(doc)
            print('\n')
        time.sleep(1)

Note: Tailable cursor only works with capped collections. It cannot be used to log operations on a collection directly, instead use filter: 'ns': 'MyDb.MyCollection'

Note: I understand that the above nodejs and python code may not be of much help for some. I have just provided the codes for reference.

Use this link to find documentation for tailable cursor in your languarge/driver choice Mongodb Drivers

Another feature that i have added after this logrotate.

Make your action empty. You don't need to set the onclick attribute, that's only javascript. When you click your submit button, it will reload your page with input from the form. So write your PHP code at the top of the form.

<?php
if( isset($_GET['submit']) )
{
    //be sure to validate and clean your variables
    $val1 = htmlentities($_GET['val1']);
    $val2 = htmlentities($_GET['val2']);

    //then you can use them in a PHP function. 
    $result = myFunction($val1, $val2);
}
?>

<?php if( isset($result) ) echo $result; //print the result above the form ?>

<form action="" method="get">
    Inserisci number1: 
    <input type="text" name="val1" id="val1"></input>

    <?php echo "ciaoooo"; ?>

    <br></br>
    Inserisci number2:
    <input type="text" name="val2" id="val2"></input>

    <br></br>

    <input type="submit" name="submit" value="send"></input>
</form>

You can use JavaScript functions like replace, and you can wrap the jQuery code in brackets:

var value = ($("#text").val()).replace(".", ":");

To complete answers in case of editing default value :

In your rails console :

rails g migration MigrationName

In the migration :

  def change
    change_column :tables, :field_name, :field_type, default: value
  end

Will look like :

  def change
    change_column :members, :approved, :boolean, default: true
  end

you could also store your data in an service with an setter and get it over a getter

import { Injectable } from '@angular/core';

@Injectable()
export class StorageService {

    public scope: Array<any> | boolean = false;

    constructor() {
    }

    public getScope(): Array<any> | boolean {
        return this.scope;
    }

    public setScope(scope: any): void {
        this.scope = scope;
    }
}

1. how to remove all the blanks lines

   :%s,\n\n,^M,g
   

   (do this multiple times util all the empty lines went gone)

2. how to remove all the blanks lines leaving SINGLE empty line

   :%s,\n\n\n,^M^M,g
   

   (do this multiple times)

3. how to remove all the blanks lines leaving TWO empty lines AT MAXIMUM,

   :%s,\n\n\n\n,^M^M^M,g
   

   (do this multiple times)

in order to input ^M, I have to control-Q and control-M in windows

Function.prototype.applyAsync = function(params, cb){
      var function_context = this;
      setTimeout(function(){
          var val = function_context.apply(undefined, params); 
          if(cb) cb(val);
      }, 0);
}

// usage
var double = function(n){return 2*n;};
var display = function(){console.log(arguments); return undefined;};
double.applyAsync([3], display);

Although not fundamentally different than the other solutions, I think my solution does a few additional nice things:

• it allows for parameters to the functions
• it passes the output of the function to the callback
• it is added to Function.prototype allowing a nicer way to call it

Also, the similarity to the built-in function Function.prototype.apply seems appropriate to me.

Try to use app:maxImageSize="56dp" instead of the above answers after you update your support library to v28.0.0

If you want to get the form data directly from Http request, without any model bindings or FormCollection you can use this:

[HttpPost] 
public ActionResult SubmitAction() {

    // This will return an string array of all keys in the form.
    // NOTE: you specify the keys in form by the name attributes e.g:
    // <input name="this is the key" value="some value" type="test" />
    var keys = Request.Form.AllKeys;

    // This will return the value for the keys.
    var value1 = Request.Form.Get(keys[0]);
    var value2 = Request.Form.Get(keys[1]);
}

This is in the JQuery documentation:

http://learn.jquery.com/using-jquery-core/faq/how-do-i-test-whether-an-element-exists/

  alert( $( "#notAnElement" ).length ? 'Not null' : 'Null' );

Here is how I did this on a SQLite database:

SELECT SUBSTR(name, 1,INSTR(name, " ")-1) as Firstname,
SUBSTR(name, INSTR(name," ")+1, LENGTH(name)) as Lastname
FROM YourTable;

Hope it helps.

1.Make Sure Website Url and platform added, if not then visit https://developers.facebook.com/quickstarts/ then Select Platform -> Setup SDK -> Website Url And so on..

Note: website url can't be like this : https://www.example.com just remove www and make it simple and working ;)

2.Goto App Dashboard -> Setting -> Click on Advanced Tab then go to bottom of the page and enable Embedded Browser OAuth Login and leave Valid OAuth redirect URIs blank and Save it

You could use reduce:

const arr = ["q", "w", "w", "e", "i", "u", "r"]
arr.reduce((acc, cur) => { 
  if(acc[cur]) {
    acc.duplicates.push(cur)
  } else {
    acc[cur] = true //anything could go here
  }
}, { duplicates: [] })

Result would look like this:

{ ...Non Duplicate Values, duplicates: ["w"] }

That way you can do whatever you want with the duplicate values!

Using jQuery UI in combination with the excellent datetimepicker plugin from http://trentrichardson.com/examples/timepicker/

You can specify the dateFormat and timeFormat

$('#datepicker').datetimepicker({
    dateFormat: "yy-mm-dd",
    timeFormat:  "hh:mm:ss"
});

I would use Application Context to get a System Service in the constructor. This eases testing & benefits from composition

public class MyActivity extends Activity {

    private final NotificationManager notificationManager;

    public MyActivity() {
       this(MyApp.getContext().getSystemService(NOTIFICATION_SERVICE));
    }

    public MyActivity(NotificationManager notificationManager) {
       this.notificationManager = notificationManager;
    }

    // onCreate etc

}

Test class would then use the overloaded constructor.

Android would use the default constructor.

There is one way to achieve this that I did not see anybody mentioning here.

By rotating the parent container by 180 degrees and the child-container again by 180 degrees the scrollbar will be shown at top

.parent {
  transform: rotateX(180deg);
  overflow-x: auto;
} 
.child {
  transform: rotateX(180deg);
}

For reference see the issue in the w3c repository.

echo $? - Gives the EXIT STATUS of the most recently executed command . This EXIT STATUS would most probably be a number with ZERO implying Success and any NON-ZERO value indicating Failure

? - This is one special parameter/variable in bash.

$? - It gives the value stored in the variable "?".

Some similar special parameters in BASH are 1,2,*,# ( Normally seen in echo command as $1 ,$2 , $* , $# , etc., ) .

If you are working with TypeScript modules and are trying to add a getter that is exported, you can do something like this:

// dataStore.ts
export const myData: string = undefined;  // just for typing support
let _myData: string;  // for memoizing the getter results

Object.defineProperty(this, "myData", {
    get: (): string => {
        if (_myData === undefined) {
            _myData = "my data";  // pretend this took a long time
        }

        return _myData;
    },
});

Then, in another file you have:

import * as dataStore from "./dataStore"
console.log(dataStore.myData); // "my data"

The absolutely best way is neither of the 2, but the 3rd. The first parameter to encode defaults to 'utf-8' ever since Python 3.0. Thus the best way is

b = mystring.encode()

This will also be faster, because the default argument results not in the string "utf-8" in the C code, but NULL, which is much faster to check!

Here be some timings:

In [1]: %timeit -r 10 'abc'.encode('utf-8')
The slowest run took 38.07 times longer than the fastest. 
This could mean that an intermediate result is being cached.
10000000 loops, best of 10: 183 ns per loop

In [2]: %timeit -r 10 'abc'.encode()
The slowest run took 27.34 times longer than the fastest. 
This could mean that an intermediate result is being cached.
10000000 loops, best of 10: 137 ns per loop

Despite the warning the times were very stable after repeated runs - the deviation was just ~2 per cent.

Using encode() without an argument is not Python 2 compatible, as in Python 2 the default character encoding is ASCII.

>>> 'äöä'.encode()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

UPDATED

I have take comments below into consideration and agreed. Eval is to be avoided.

Accessing root properties in object is easily achieved with obj[variable], but getting nested complicates thing. Not to write already written code I suggest to use lodash.get.

Example

// Accessing root property
var rootProp = 'rootPropert';
_.get(object, rootProp, defaultValue);

// Accessing nested property
var listOfNestedProperties = [var1, var2];
_.get(object, listOfNestedProperties);

Lodash get can be used on different ways, here is link to the documentation lodash.get

well bubble sort is better than insertion sort only when someone is looking for top k elements from a large list of number i.e. in bubble sort after k iterations you'll get top k elements. However after k iterations in insertion sort, it only assures that those k elements are sorted.

C# supports two boolean or operators: the single bar | and the double-bar ||.

The difference is that | always checks both the left and right conditions, while || only checks the right-side condition if it's necessary (if the left side evaluates to false).

This is significant when the condition on the right-side involves processing or results in side effects. (For example, if your ErrorDumpWriter.Close method took a while to complete or changed something's state.)

This is probably more verbose than you want, but you're asking for a slightly complex operation so actual code might be involved (the horror).

My recommendation, with zipObject that's pretty logical:

_.zipObject(_.map(params, 'name'), _.map(params, 'input'));

Another option, more hacky, using fromPairs:

_.fromPairs(_.map(params, function(val) { return [val['name'], val['input']));

The anonymous function shows the hackiness -- I don't believe JS guarantees order of elements in object iteration, so callling .values() won't do.

Refer to the ASP.NET page lifecycle to help find the right event to override. It really depends what you want to do. But yes, there is an unload event.

    protected override void OnUnload(EventArgs e)
    {
        base.OnUnload(e);

        // your code
    }

But just remember (from the above link): During the unload stage, the page and its controls have been rendered, so you cannot make further changes to the response stream. If you attempt to call a method such as the Response.Write method, the page will throw an exception.

If your running php5 you can use:

$url = 'http://www.example.com';
print_r(get_headers($url, 1));

Alternatively with php4 a user has contributed the following:

/**
This is a modified version of code from "stuart at sixletterwords dot com", at 14-Sep-2005 04:52. This version tries to emulate get_headers() function at PHP4. I think it works fairly well, and is simple. It is not the best emulation available, but it works.

Features:
- supports (and requires) full URLs.
- supports changing of default port in URL.
- stops downloading from socket as soon as end-of-headers is detected.

Limitations:
- only gets the root URL (see line with "GET / HTTP/1.1").
- don't support HTTPS (nor the default HTTPS port).
*/

if(!function_exists('get_headers'))
{
    function get_headers($url,$format=0)
    {
        $url=parse_url($url);
        $end = "\r\n\r\n";
        $fp = fsockopen($url['host'], (empty($url['port'])?80:$url['port']), $errno, $errstr, 30);
        if ($fp)
        {
            $out  = "GET / HTTP/1.1\r\n";
            $out .= "Host: ".$url['host']."\r\n";
            $out .= "Connection: Close\r\n\r\n";
            $var  = '';
            fwrite($fp, $out);
            while (!feof($fp))
            {
                $var.=fgets($fp, 1280);
                if(strpos($var,$end))
                    break;
            }
            fclose($fp);

            $var=preg_replace("/\r\n\r\n.*\$/",'',$var);
            $var=explode("\r\n",$var);
            if($format)
            {
                foreach($var as $i)
                {
                    if(preg_match('/^([a-zA-Z -]+): +(.*)$/',$i,$parts))
                        $v[$parts[1]]=$parts[2];
                }
                return $v;
            }
            else
                return $var;
        }
    }
}

Both would have a result similar to:

Array
(
    [0] => HTTP/1.1 200 OK
    [Date] => Sat, 29 May 2004 12:28:14 GMT
    [Server] => Apache/1.3.27 (Unix)  (Red-Hat/Linux)
    [Last-Modified] => Wed, 08 Jan 2003 23:11:55 GMT
    [ETag] => "3f80f-1b6-3e1cb03b"
    [Accept-Ranges] => bytes
    [Content-Length] => 438
    [Connection] => close
    [Content-Type] => text/html
)

Therefore you could just check to see that the header response was OK eg:

$headers = get_headers($url, 1);
if ($headers[0] == 'HTTP/1.1 200 OK') {
//valid 
}

if ($headers[0] == 'HTTP/1.1 301 Moved Permanently') {
//moved or redirect page
}

W3C Codes and Definitions

Just develop a normal app and then add a couple of lines to the app's manifest file.

First you need to add the following attribute to your activity:

            android:launchMode="singleTask"

Then add two categories to the intent filter :

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.HOME" />

The result could look something like this:

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.dummy.app"
        android:versionCode="1"
        android:versionName="1.0" >

        <uses-sdk
            android:minSdkVersion="11"
            android:targetSdkVersion="19" />

        <application
            android:allowBackup="true"
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/AppTheme" >
            <activity
                android:name="com.dummy.app.MainActivity"
                android:launchMode="singleTask"
                android:label="@string/app_name" >
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
                    <category android:name="android.intent.category.DEFAULT" />
                    <category android:name="android.intent.category.HOME" />
                </intent-filter>
            </activity>
        </application>

    </manifest>

It's that simple!

 1, Map<String, List<String>> map = new HashMap<>();

this verbose solution has multiple drawbacks and is prone to errors. It implies that we need to instantiate a Collection for every value, check for its presence before adding or removing a value, delete it manually when no values are left, etcetera.

Use arrays:

{
    "number": ["1", "2", "3"],
    "alphabet": ["a", "b", "c"]
}

You can the access the different values from their position in the array. Counting starts at left of array at 0. myJsonObject["number"][0] == 1 or myJsonObject["alphabet"][2] == 'c'

You could use a dictionary. The definition is the same. But to save you time, Overhead is work required to do the productive work. For instance, an algorithm runs and does useful work, but requires memory to do its work. This memory allocation takes time, and is not directly related to the work being done, therefore is overhead.

I've generalized Piotr Stapp's JavaScript/jQuery method a bit further, encapsulating it into a function and generalizing it a bit.

This function uses the RabbitMQ HTTP API to query available queues in a given vhost, and then delete them based on an optional queuePrefix:

function deleteQueues(vhost, queuePrefix) {
    if (vhost === '/') vhost = '%2F';  // html encode forward slashes
    $.ajax({
        url: '/api/queues/'+vhost, 
        success: function(result) {
            $.each(result, function(i, queue) {
                if (queuePrefix && !queue.name.startsWith(queuePrefix)) return true;
                $.ajax({
                    url: '/api/queues/'+vhost+'/'+queue.name, 
                    type: 'DELETE', 
                    success: function(result) { console.log('deleted '+ queue.name)}
                });
            });
        }
    });
};

Once you paste this function in your browser's JavaScript console while on your RabbitMQ management page, you can use it like this:

Delete all queues in '/' vhost

deleteQueues('/');

Delete all queues in '/' vhost beginning with 'test'

deleteQueues('/', 'test');

Delete all queues in 'dev' vhost beginning with 'foo'

deleteQueues('dev', 'foo');

Please use this at your own risk!

My modified answer from @oconnecp (https://stackoverflow.com/a/25069828/3027390)

Uses path.join for better cross-platform experience. So, don't forget to require it.

var path = require('path');

Also renamed function to rimraf ;)

/**
 * Remove directory recursively
 * @param {string} dir_path
 * @see https://stackoverflow.com/a/42505874/3027390
 */
function rimraf(dir_path) {
    if (fs.existsSync(dir_path)) {
        fs.readdirSync(dir_path).forEach(function(entry) {
            var entry_path = path.join(dir_path, entry);
            if (fs.lstatSync(entry_path).isDirectory()) {
                rimraf(entry_path);
            } else {
                fs.unlinkSync(entry_path);
            }
        });
        fs.rmdirSync(dir_path);
    }
}

With the module pygame.draw shapes like rectangles, circles, polygons, liens, ellipses or arcs can be drawn. Some examples:

pygame.draw.rect draws filled rectangular shapes or outlines. The arguments are the target Surface (i.s. the display), the color, the rectangle and the optional outline width. The rectangle argument is a tuple with the 4 components (x, y, width, height), where (x, y) is the upper left point of the rectangle. Alternatively, the argument can be a pygame.Rect object:

pygame.draw.rect(window, color, (x, y, width, height))

rectangle = pygame.Rect(x, y, width, height)
pygame.draw.rect(window, color, rectangle)

pygame.draw.circle draws filled circles or outlines. The arguments are the target Surface (i.s. the display), the color, the center, the radius and the optional outline width. The center argument is a tuple with the 2 components (x, y):

pygame.draw.circle(window, color, (x, y), radius)

pygame.draw.polygon draws filled polygons or contours. The arguments are the target Surface (i.s. the display), the color, a list of points and the optional contour width. Each point is a tuple with the 2 components (x, y):

pygame.draw.polygon(window, color, [(x1, y1), (x2, y2), (x3, y3)])

Minimal example:

import pygame

pygame.init()

window = pygame.display.set_mode((200, 200))
clock = pygame.time.Clock()

run = True
while run:
    clock.tick(60)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    window.fill((255, 255, 255))

    pygame.draw.rect(window, (0, 0, 255), (20, 20, 160, 160))
    pygame.draw.circle(window, (255, 0, 0), (100, 100), 80)
    pygame.draw.polygon(window, (255, 255, 0), 
        [(100, 20), (100 + 0.8660 * 80, 140), (100 - 0.8660 * 80, 140)])

    pygame.display.flip()

pygame.quit()
exit()

To delete a normal stash created with git stash , you want git stash drop or git stash drop stash@{n}. See below for more details.

You don't need to delete a stash created with git stash create. From the docs:

Create a stash entry (which is a regular commit object) and return its object name, without storing it anywhere in the ref namespace. This is intended to be useful for scripts. It is probably not the command you want to use; see "save" above.

Since nothing references the stash commit, it will get garbage collected eventually.

A stash created with git stash or git stash save is saved to refs/stash, and can be deleted with git stash drop. As with all Git objects, the actual stash contents aren't deleted from your computer until a gc prunes those objects after they expire (default is 2 weeks later).

Older stashes are saved in the refs/stash reflog (try cat .git/logs/refs/stash), and can be deleted with git stash drop stash@{n}, where n is the number shown by git stash list.

Cells(1,1).Select

It will take you to cell A1, thereby canceling your existing selection.

I had the same problem. In my case, even though I have not understood why, the problem was due to & in one of the elements like the following where a and b are two tokens/words:

<s> . . . a & b . . . </s>

and to resolve the issue I turned my element's text to the following:

<s> . . . a and b . . . </s>

I thought it might be the case for some of you. Generally, to make your life easier, just go and read the character at the index mentioned in the error message (line:..., col:...) and see what the character is.

You can add multiple only by code even if you have the second onclick atribute in the html it gets ignored, and click2 triggered never gets printed, you could add one on action the mousedown but that is just an workaround.

So the best to do is add them by code as in:

var element = document.getElementById("multiple_onclicks");_x000D_
element.addEventListener("click", function(){console.log("click3 triggered")}, false);_x000D_
element.addEventListener("click", function(){console.log("click4 triggered")}, false);

<button id="multiple_onclicks" onclick='console.log("click1 triggered");' onclick='console.log("click2 triggered");' onmousedown='console.log("click mousedown triggered");'  > Click me</button>

You need to take care as the events can pile up, and if you would add many events you can loose count of the order they are ran.

List<String> list = new ArrayList<String>(Arrays.asList("", "Hi", null, "How"));
System.out.println(list);
list.removeAll(Arrays.asList("", null));
System.out.println(list);

Output:

[, Hi, null, How]
[Hi, How]

Yes, you can do this in PHP e.g. in

Silex or Symfony3

using subrequest

$postParams = array(
    'email' => $request->get('email'),
    'agree_terms' => $request->get('agree_terms'),
);

$subRequest = Request::create('/register', 'POST', $postParams);
return $app->handle($subRequest, HttpKernelInterface::SUB_REQUEST, false);

I imported in some files from bridgin header files from cocoapods not in a proper way.

Instead of importing

#import <SomeCocoaPod/SomeCocoaPod.h>

I wrote

#import "SomeCocoaPod.h"

And this was my HUGE mistake

It seems the issue is in "-f ($_.Partition.Size/1GB)}}" If you want the value in MB then change the 1GB to 1MB.

With visibility:hidden the object still takes up vertical height on the page. With display:none it is completely removed. If you have text beneath an image and you do display:none, that text will shift up to fill the space where the image was. If you do visibility:hidden the text will remain in the same location.

I also tried to make an executable jar file that I could run with the following command:

java -jar <jarfile>

After some searching I found the following link:

Packaging and Deploying Desktop Java Applications

I set the project's main class:

1. Right-click the project's node and choose Properties
2. Select the Run panel and enter the main class in the Main Class field
3. Click OK to close the Project Properties dialog box
4. Clean and build project

Then in the fodler dist the newly created jar should be executable with the command I mentioned above.

to anyone who's using react-moment:

import Moment from 'react-moment'

inside render (use format prop to your needed format):

const now = new Date()
<Moment format="MM/DD/YYYY">{now}</Moment>

You can use:

list.addAll(Arrays.asList(array));

I think there is little difference between the two events. To understand this, I created a simple example to manipulation:

XAML

<Window x:Class="LoadedAndContentRendered.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Name="MyWindow"
        Title="MainWindow" Height="1000" Width="525"
        WindowStartupLocation="CenterScreen"
        ContentRendered="Window_ContentRendered"     
        Loaded="Window_Loaded">

    <Grid Name="RootGrid">        
    </Grid>
</Window>

Code behind

private void Window_ContentRendered(object sender, EventArgs e)
{
    MessageBox.Show("ContentRendered");
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    MessageBox.Show("Loaded");
}   

In this case the message Loaded appears the first after the message ContentRendered. This confirms the information in the documentation.

In general, in WPF the Loaded event fires if the element:

is laid out, rendered, and ready for interaction.

Since in WPF the Window is the same element, but it should be generally content that is arranged in a root panel (for example: Grid). Therefore, to monitor the content of the Window and created an ContentRendered event. Remarks from MSDN:

If the window has no content, this event is not raised.

That is, if we create a Window:

<Window x:Class="LoadedAndContentRendered.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Name="MyWindow"        
    ContentRendered="Window_ContentRendered" 
    Loaded="Window_Loaded" />

It will only works Loaded event.

With regard to access to the elements in the Window, they work the same way. Let's create a Label in the main Grid of Window. In both cases we have successfully received access to Width:

private void Window_ContentRendered(object sender, EventArgs e)
{
    MessageBox.Show("ContentRendered: " + SampleLabel.Width.ToString());
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    MessageBox.Show("Loaded: " + SampleLabel.Width.ToString());
}   

As for the Styles and Templates, at this stage they are successfully applied, and in these events we will be able to access them.

For example, we want to add a Button:

private void Window_ContentRendered(object sender, EventArgs e)
{
    MessageBox.Show("ContentRendered: " + SampleLabel.Width.ToString());

    Button b1 = new Button();
    b1.Content = "ContentRendered Button";
    RootGrid.Children.Add(b1);
    b1.Height = 25;
    b1.Width = 200;
    b1.HorizontalAlignment = HorizontalAlignment.Right;
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    MessageBox.Show("Loaded: " + SampleLabel.Width.ToString());

    Button b1 = new Button();
    b1.Content = "Loaded Button";
    RootGrid.Children.Add(b1);
    b1.Height = 25;
    b1.Width = 200;
    b1.HorizontalAlignment = HorizontalAlignment.Left;
}

In the case of Loaded event, Button to add to Grid immediately at the appearance of the Window. In the case of ContentRendered event, Button to add to Grid after all its content will appear.

Therefore, if you want to add items or changes before load Window you must use the Loaded event. If you want to do the operations associated with the content of Window such as taking screenshots you will need to use an event ContentRendered.

To select the first row from a table and to select one row from a table are two different tasks and need a different query. There are many possible ways to do so. Four of them are:

First

select  max(Fname) from MyTbl;

Second

select  min(Fname) from MyTbl;

Third

select  Fname from MyTbl  where rownum = 1;

Fourth

select  max(Fname) from MyTbl where rowid=(select  max(rowid) from MyTbl)

This can be pretty easy and simple

obj.name = "Raj";
obj.age = 32;
obj.married = false;

//convert object to json string
var string = JSON.stringify(obj);

//convert string to Json Object

Flask will process one request per thread at the same time. If you have 2 processes with 4 threads each, that's 8 concurrent requests.

Flask doesn't spawn or manage threads or processes. That's the responsability of the WSGI gateway (eg. gunicorn).

Contrary to the suggestions by some of the other answers, using the DllImport attribute is still the correct approach.

I honestly don't understand why you can't do just like everyone else in the world and specify a relative path to your DLL. Yes, the path in which your application will be installed differs on different people's computers, but that's basically a universal rule when it comes to deployment. The DllImport mechanism is designed with this in mind.

In fact, it isn't even DllImport that handles it. It's the native Win32 DLL loading rules that govern things, regardless of whether you're using the handy managed wrappers (the P/Invoke marshaller just calls LoadLibrary). Those rules are enumerated in great detail here, but the important ones are excerpted here:

Before the system searches for a DLL, it checks the following:

• If a DLL with the same module name is already loaded in memory, the system uses the loaded DLL, no matter which directory it is in. The system does not search for the DLL.
• If the DLL is on the list of known DLLs for the version of Windows on which the application is running, the system uses its copy of the known DLL (and the known DLL's dependent DLLs, if any). The system does not search for the DLL.

If SafeDllSearchMode is enabled (the default), the search order is as follows:

1. The directory from which the application loaded.
2. The system directory. Use the GetSystemDirectory function to get the path of this directory.
3. The 16-bit system directory. There is no function that obtains the path of this directory, but it is searched.
4. The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
5. The current directory.
6. The directories that are listed in the PATH environment variable. Note that this does not include the per-application path specified by the App Paths registry key. The App Paths key is not used when computing the DLL search path.

So, unless you're naming your DLL the same thing as a system DLL (which you should obviously not be doing, ever, under any circumstances), the default search order will start looking in the directory from which your application was loaded. If you place the DLL there during the install, it will be found. All of the complicated problems go away if you just use relative paths.

Just write:

[DllImport("MyAppDll.dll")] // relative path; just give the DLL's name
static extern bool MyGreatFunction(int myFirstParam, int mySecondParam);

But if that doesn't work for whatever reason, and you need to force the application to look in a different directory for the DLL, you can modify the default search path using the SetDllDirectory function.
Note that, as per the documentation:

After calling SetDllDirectory, the standard DLL search path is:

1. The directory from which the application loaded.
2. The directory specified by the lpPathName parameter.
3. The system directory. Use the GetSystemDirectory function to get the path of this directory.
4. The 16-bit system directory. There is no function that obtains the path of this directory, but it is searched.
5. The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
6. The directories that are listed in the PATH environment variable.

So as long as you call this function before you call the function imported from the DLL for the first time, you can modify the default search path used to locate DLLs. The benefit, of course, is that you can pass a dynamic value to this function that is computed at run-time. That isn't possible with the DllImport attribute, so you will still use a relative path (the name of the DLL only) there, and rely on the new search order to find it for you.

You'll have to P/Invoke this function. The declaration looks like this:

[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern bool SetDllDirectory(string lpPathName);

IF EXIST "somefile.txt" (
  IF EXIST "someotherfile.txt" (
    SET var="somefile.txt","someotherfile.txt"
  )
) ELSE (
  CALL :SUB
)
:SUB
ECHO Sorry... nothin' there.
GOTO:EOF

Is this feasible?

SETLOCAL ENABLEDELAYEDEXPANSION
IF EXIST "somefile.txt" (
  SET var="somefile.txt"
  IF EXIST "someotherfile.txt" (
    SET var=!var!,"someotherfile.txt"
  )
) ELSE (
  IF EXIST "someotherfile.txt" (
    SET var="someotherfile.txt"
  ) ELSE (
  GOTO:EOF
  )
)

They are not really same mutexes, lock_guard<muType> has nearly the same as std::mutex, with a difference that it's lifetime ends at the end of the scope (D-tor called) so a clear definition about these two mutexes :

lock_guard<muType> has a mechanism for owning a mutex for the duration of a scoped block.

And

unique_lock<muType> is a wrapper allowing deferred locking, time-constrained attempts at locking, recursive locking, transfer of lock ownership, and use with condition variables.

Here is an example implemetation :

#include <iostream>
#include <thread>
#include <mutex>
#include <condition_variable>
#include <functional>
#include <chrono>

using namespace std::chrono;

class Product{

   public:

       Product(int data):mdata(data){
       }

       virtual~Product(){
       }

       bool isReady(){
       return flag;
       }

       void showData(){

        std::cout<<mdata<<std::endl;
       }

       void read(){

         std::this_thread::sleep_for(milliseconds(2000));

         std::lock_guard<std::mutex> guard(mmutex);

         flag = true;

         std::cout<<"Data is ready"<<std::endl;

         cvar.notify_one();

       }

       void task(){

       std::unique_lock<std::mutex> lock(mmutex);

       cvar.wait(lock, [&, this]() mutable throw() -> bool{ return this->isReady(); });

       mdata+=1;

       }

   protected:

    std::condition_variable cvar;
    std::mutex mmutex;
    int mdata;
    bool flag = false;

};

int main(){

     int a = 0;
     Product product(a);

     std::thread reading(product.read, &product);
     std::thread setting(product.task, &product);

     reading.join();
     setting.join();


     product.showData();
    return 0;
}

In this example, i used the unique_lock<muType> with condition variable

You cannot have snapshot isolation and blocking reads at the same time. The purpose of snapshot isolation is to prevent blocking reads.

Using Swift 3 or 4 you can access these http request for sever communication.

I tried everything except this. After rigorous trials,Uninstalling java 8 update 25 helped me.

Check:

$ sysctl kernel.core_pattern

to see how your dumps are created (%e will be the process name, and %t will be the system time).

If you've Ubuntu, your dumps are created by apport in /var/crash, but in different format (edit the file to see it).

You can test it by:

sleep 10 &
killall -SIGSEGV sleep

If core dumping is successful, you will see “(core dumped)” after the segmentation fault indication.

Well first of all there's no such thing as "arrays" in Python, Python uses lists and that does make a difference, I suggest you use NumPy which is a pretty good library for Python and it adds a lot of Matlab-like functionality.You can get started here Numpy for Matlab users

Yes, you can use Visual Studio for Android (native) using "vs-android".

Here are the steps to set it up:

1. Download the Android SDK here.

2. Download the Android NDK here.

3. Download Cygwin here.

4. Download the JDK here.

5. Download Visual Studio 2010, 2012 or 2013 here.

6. Download vs-android here.

7. Download Apache Ant here.

8. Set environment variables:

(Control Panel > System > Advanced > Environment Variables)

ANDROID_HOME = <install_path>\android-sdk
ANDROID_NDK_ROOT = <install_path>\android-ndk
ANT_HOME  = <install_path>\apache-ant
JAVA_HOME = <install_path>\jdk
_JAVA_OPTIONS = -Xms256m -Xmx512m  

9. Download examples from here.

It works like a charm... and best so far to use.

Complete example of File upload using Angular and nodejs(express)

HTML Code

FOR the best performance, use specific column name instead of * - for example:

SELECT TOP 1 <columnName> 
FROM <tableName> 

This is optimal because, instead of returning the whole list of columns, it is returning just one. That can save some time.

Also, returning just first row if there are any values, makes it even faster. Actually you got just one value as the result - if there are any rows, or no value if there is no rows.

If you use the table in distributed manner, which is most probably the case, than transporting just one value from the server to the client is much faster.

You also should choose wisely among all the columns to get data from a column which can take as less resource as possible.

I wrote two applications, one medium sized, and the other, fairly small. I'd fire up the medium sized one (on linux, centos), without any args, (java server), and it would run just fine. But when I then fired up the smaller app with "java client", it would tell me it couldn't reserve enough space, and wouldn't run. I experimented, and used the -Xms and -Xmx both with 10m, and they would both run without complaint... Go figure!

What you can do is to hide the ReCaptcha Control behind a div. Then make your styling on this div. And set the css "pointer-events: none" on it, so you can click through the div (Click through a DIV to underlying elements).

The checkbox should be in a place where the user is clicking.

Sometimes, when you add a new library, in introduces a clashing version of System.Windows.Interactivity.dll.

For example, the NuGet package MVVM light might require v4.2 of System.Windows.Interactivity.dll, but the NuGet package Rx-XAML might require v4.5 of System.Windows.Interactivity.dll. This will prevent the the project from working, because no matter which version of System.Windows.Interactivity.dll you include, one of the libraries will refuse to compile.

To fix, add an Assembly Binding Redirect by editing your app.config to look something like this:

<?xml version="1.0"?>
<configuration>
<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>
      <assemblyIdentity name="System.Windows.Interactivity"
                        publicKeyToken="31bf3856ad364e35"
                        culture="neutral"/>
      <bindingRedirect oldVersion="4.0.0.0"
                       newVersion="4.5.0.0" />
    </dependentAssembly>
  </assemblyBinding>
</runtime>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/></startup>
<appSettings>
  <add key="TestKey" value="true"/>
</appSettings>

Don't worry about changing the PublicKeyToken, that's constant across all versions, as it depends on the name of the .dll, not the version.

Ensure that you match the newVersion in your appConfig to the actual version that you end up pointing at:

Most of these answers use sp_executesql as the solution to this problem. I have found that there are some limitations when using sp_executesql, which I will not go into, but I wanted to offer an alternative using EXEC(). I am using SQL Server 2008 and I know that some of the objects I am using in this script are not available in earlier versions of SQL Server so be wary.

DECLARE @CountResults TABLE (CountReturned INT)
DECLARE 
    @SqlStatement VARCHAR(8000) = 'SELECT COUNT(*) FROM table'
    , @Count INT

INSERT @CountResults
EXEC(@SqlStatement)

SET @Count = (SELECT CountReturned FROM @CountResults)
SELECT @Count

Same issue i got, i did following steps,

1. git init
2. git add .
3. git commit -m"inital setup"
4. git push -f origin master

then it work starts working.

So in general dll has to be placed in two places:

1. GAC ( can have 32 and 64 versions of dll's)
2. your project bin folder

Thus, you just need add reference to log4net.dll. (In your case 32-bit with PublicKeyToken=692fbea5521e1304)

You can achive that by

• downloading log4net.dll separately and add reference to it
• dowloading SAP crystal report SDK (32 bit) https://wiki.scn.sap.com/wiki/display/BOBJ/Crystal+Reports%2C+Developer+for+Visual+Studio+Downloads

Just about any error will throw an exceptions. The only errors I can think of that wouldn't work with the "pause on exceptions" option are syntax errors, which happen before any of the code gets executed, so there's no place to pause anyway and none of the code will run.

Apparently, Chrome won't pause on the exception if it's inside a try-catch block though. It only pauses on uncaught exceptions. I don't know of any way to change it.

If you just need to know what line the exception happened on (then you could set a breakpoint if the exception is reproducible), the Error object given to the catch block has a stack property that shows where the exception happened.

The filter method should do the trick:

const myArray = ['a', 'b', 'c', 'd', 'e', 'f', 'g'];
const toRemove = ['b', 'c', 'g'];

// ES5 syntax
const filteredArray = myArray.filter(function(x) { 
  return toRemove.indexOf(x) < 0;
});

If your toRemove array is large, this sort of lookup pattern can be inefficient. It would be more performant to create a map so that lookups are O(1) rather than O(n).

const toRemoveMap = toRemove.reduce(
  function(memo, item) {
    memo[item] = memo[item] || true;
    return memo;
  },
  {} // initialize an empty object
);

const filteredArray = myArray.filter(function (x) {
  return toRemoveMap[x];
});

// or, if you want to use ES6-style arrow syntax:
const toRemoveMap = toRemove.reduce((memo, item) => ({
  ...memo,
  [item]: true
}), {});

const filteredArray = myArray.filter(x => toRemoveMap[x]);

You must use a tool called a "header". In a header you declare the function that you want to use. Then you include it in both files. A header is a separate file included using the #include directive. Then you may call the other function.

other.h

void MyFunc();

main.cpp

#include "other.h"
int main() {
    MyFunc();
}

other.cpp

#include "other.h"
#include <iostream>
void MyFunc() {
    std::cout << "Ohai from another .cpp file!";
    std::cin.get();
}

document.forms[0].elements[0].focus();

This can be refined using a loop to eg. not focus certain types of field, disabled fields and so on. Better may be to add a class="autofocus" to the field you actually do want focused, and loop over forms[i].elements[j] looking for that className.

Anyhow: it's not normally a good idea to do this on every page. When you focus an input the user loses the ability to eg. scroll the page from the keyboard. If unexpected, this can be annoying, so only auto-focus when you're pretty sure that using the form field is going to be what the user wants to do. ie. if you're Google.

'pywin32' is its canonical name.

http://sourceforge.net/projects/pywin32/

If you are using Pipenv, you may need to add this to your Pipfile:

[packages]
python-dateutil = "*"

I suggest to see the classic example at: http://maven.apache.org/guides/getting-started/index.html#How_do_I_build_more_than_one_project_at_once

Here my-webapp is web project, which depends on the code at my-app project. So to bundle two projects in one, we have top level pom.xml which mentions which are the projects (modules as per maven terminology) to be bundled finally. Such top level pom.xml can use pom packaging.

my-webapp can have war packaging and can have dependency on my-app. my-app can have jar packaging.

After trying some suggestions and seeing issues in IE here is the one that works:

https://github.com/parndt/jquery-html5-placeholder-shim/

What I have liked - you just include the js file. No need to initiate it or anything.

If you need to set the new value based on the old field value that is do something like:

update my_table set field_1 = field_1 + 1 where pk_field = some_value

use query expressions:

MyModel.objects.filter(pk=some_value).update(field1=F('field1') + 1)

This will execute update atomically that is using one update request to the database without reading it first.

1. SynchronousQueue ( Taken from another question )

SynchronousQueue is more of a handoff, whereas the LinkedBlockingQueue just allows a single element. The difference being that the put() call to a SynchronousQueue will not return until there is a corresponding take() call, but with a LinkedBlockingQueue of size 1, the put() call (to an empty queue) will return immediately. It's essentially the BlockingQueue implementation for when you don't really want a queue (you don't want to maintain any pending data).

2. LinkedBlockingQueue (LinkedList Implementation but Not Exactly JDK Implementation of LinkedList It uses static inner class Node to maintain Links between elements )

Constructor for LinkedBlockingQueue

public LinkedBlockingQueue(int capacity) 
{
        if (capacity < = 0) throw new IllegalArgumentException();
        this.capacity = capacity;
        last = head = new Node< E >(null);   // Maintains a underlying linkedlist. ( Use when size is not known )
}

Node class Used to Maintain Links

static class Node<E> {
    E item;
    Node<E> next;
    Node(E x) { item = x; }
}

3 . ArrayBlockingQueue ( Array Implementation )

Constructor for ArrayBlockingQueue

public ArrayBlockingQueue(int capacity, boolean fair) 
{
            if (capacity < = 0)
                throw new IllegalArgumentException();
            this.items = new Object[capacity]; // Maintains a underlying array
            lock = new ReentrantLock(fair);
            notEmpty = lock.newCondition();
            notFull =  lock.newCondition();
}

IMHO Biggest Difference between ArrayBlockingQueue and LinkedBlockingQueue is clear from constructor one has underlying data structure Array and other linkedList.

ArrayBlockingQueue uses single-lock double condition algorithm and LinkedBlockingQueue is variant of the "two lock queue" algorithm and it has 2 locks 2 conditions ( takeLock , putLock)

i wrote it today in C,compiled with tcc, figured out during preparation of compititive exams several years back. don't know if anyone already have wrote it alredy. it really fast(but you should decide whether it is fast or not). took one or two minuts to findout about 1,00,004 prime numbers between 10 and 1,00,00,000 on i7 processor with average 32% CPU use. as you know, only those can be prime which have last digit either 1,3,7 or 9 and to check if that number is prime or not, you have to divide that number by previously found prime numbers only. so first take group of four number = {1,3,7,9}, test it by dividing by known prime numbers, if reminder is non zero then number is prime, add it to prime number array. then add 10 to group so it becomes {11,13,17,19} and repeat the process.

Simple solution to drop all the table at once from terminal.

This involved few steps inside your mysql shell (not a one step solution though), this worked me and saved my day.

Worked for Server version: 5.6.38 MySQL Community Server (GPL)

Steps I followed:

 1. generate drop query using concat and group_concat.
 2. use database
 3. turn off / disable foreign key constraint check (SET FOREIGN_KEY_CHECKS = 0;), 
 4. copy the query generated from step 1
 5. re enable foreign key constraint check (SET FOREIGN_KEY_CHECKS = 1;)
 6. run show table

MySQL shell

$ mysql -u root -p
Enter password: ****** (your mysql root password)
mysql> SYSTEM CLEAR;
mysql> SELECT CONCAT('DROP TABLE IF EXISTS `', GROUP_CONCAT(table_name SEPARATOR '`, `'), '`;') AS dropquery FROM information_schema.tables WHERE table_schema = 'emall_duplicate';

It's a good idea that logging actual data into "customer_data" table. With this data you can select all data from "customer_data" table as you wish.

So I have ElementTree 1.2.6 on my box now, and ran the following code against the XML chunk you posted:

import elementtree.ElementTree as ET

tree = ET.parse("test.xml")
doc = tree.getroot()
thingy = doc.find('timeSeries')

print thingy.attrib

and got the following back:

{'name': 'NWIS Time Series Instantaneous Values'}

It appears to have found the timeSeries element without needing to use numerical indices.

What would be useful now is knowing what you mean when you say "it doesn't work." Since it works for me given the same input, it is unlikely that ElementTree is broken in some obvious way. Update your question with any error messages, backtraces, or anything you can provide to help us help you.

Configure XCode project settings, it can solve your problem.

Try this,

int dialogButton = JOptionPane.YES_NO_OPTION;
int dialogResult = JOptionPane.showConfirmDialog(this, "Your Message", "Title on Box", dialogButton);
if(dialogResult == 0) {
  System.out.println("Yes option");
} else {
  System.out.println("No Option");
} 

You don't. The closest thing you can do is working with Maps to simulate it, or defining your own Objects to deal with.

have a look at http://www.pixelbeat.org/talks/python/ls.py

You can't use variable names to bind columns or other system objects, you need dynamic sql

DECLARE @value varchar(10)  
SET @value = 'intStep'  
DECLARE @sqlText nvarchar(1000); 

SET @sqlText = N'SELECT ' + @value + ' FROM dbo.tblBatchDetail'
Exec (@sqlText)

In java8, I would use the Instant class which is already in UTC and is convenient to work with.

import java.time.Instant;

Instant ins = Instant.now();
long ts = ins.toEpochMilli();

Instant ins2 = Instant.ofEpochMilli(ts)

Alternatively, you can use the following:

import java.time.*;

Instant ins = Instant.now(); 

OffsetDateTime odt = ins.atOffset(ZoneOffset.UTC);
ZonedDateTime zdt = ins.atZone(ZoneId.of("UTC"));

Back to Instant

Instant ins4 = Instant.from(odt);

The results are ordered by the first column, then the second, and so on for as many columns as the ORDER BY clause includes. If you want any results sorted in descending order, your ORDER BY clause must use the DESC keyword directly after the name or the number of the relevant column.

Check out this Example

SELECT first_name, last_name, hire_date, salary 
FROM employee 
ORDER BY hire_date DESC,last_name ASC;

It will order in succession. Order the Hire_Date first, then LAST_NAME it by Hire_Date .

All these input keyevent combinations are SO android/hardware dependent, it's a pain.

However, I finally found the combination for my old android 4.1 device :

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings
adb shell "input keyevent KEYCODE_DPAD_LEFT;input keyevent KEYCODE_DPAD_RIGHT;input keyevent KEYCODE_DPAD_CENTER"

Set the Maximise property to False.

Try Following

DECLARE @formatted_datetime char(23)
SET @formatted_datetime = CONVERT(char(23), GETDATE(), 121)
print @formatted_datetime

While moopasta's answer works, it doesn't appear to allow wildcards and there is another (potentially better) option. The Chromium project has some HTTP authentication documentation that is useful but incomplete.

Specifically the option that I found best is to whitelist sites that you would like to allow Chrome to pass authentication information to, you can do this by:

• Launching Chrome with the auth-server-whitelist command line switch. e.g. --auth-server-whitelist="*example.com,*foobar.com,*baz". Downfall to this approach is that opening links from other programs will launch Chrome without the command line switch.
• Installing, enabling, and configuring the AuthServerWhitelist/"Authentication server whitelist" Group Policy or Local Group Policy. This seems like the most stable option but takes more work to setup. You can set this up locally, no need to have this remotely deployed.

Those looking to set this up for an enterprise can likely follow the directions for using Group Policy or the Admin console to configure the AuthServerWhitelist policy. Those looking to set this up for one machine only can also follow the Group Policy instructions:

1. Download and unzip the latest Chrome policy templates
2. Start > Run > gpedit.msc
3. Navigate to Local Computer Policy > Computer Configuration > Administrative Templates
4. Right-click Administrative Templates, and select Add/Remove Templates
5. Add the windows\adm\en-US\chrome.adm template via the dialog
6. In Computer Configuration > Administrative Templates > Classic Administrative Templates > Google > Google Chrome > Policies for HTTP Authentication enable and configure Authentication server whitelist
7. Restart Chrome and navigate to chrome://policy to view active policies

Just a little addition to psycho brm´s answer (his version doesn't work in IE<=8). This code is cross-browser compatible:

function explode (s, separator, limit)
{
    var arr = s.split(separator);
    if (limit) {
        arr.push(arr.splice(limit-1, (arr.length-(limit-1))).join(separator));
    }
    return arr;
}

:: is a operator of defining the namespace.

For example, if you want to use cout without mentioning using namespace std; in your code you write this:

std::cout << "test";

When no namespace is mentioned, that it is said that class belongs to global namespace.

The .browser call has been removed in jquery 1.9 have a look at http://jquery.com/upgrade-guide/1.9/ for more details.

You can use date(t_stamp) to get only the date part from a timestamp.

You can check the date() function in the docs

DATE(expr)

Extracts the date part of the date or datetime expression expr.

mysql> SELECT DATE('2003-12-31 01:02:03'); -> '2003-12-31'

If it has to be "nested", this would be one way, to get your job done:

SELECT o.name AS country, o.headofstate 
FROM   country o
WHERE  o.headofstate like 'A%'
AND   (
    SELECT i.population
    FROM   city i
    WHERE  i.id = o.capital
    ) > 100000

A JOIN would be more efficient than a correlated subquery, though. Can it be, that who ever gave you that task is not up to speed himself?

To get the data form external site by passing using a local proxy as suggested by jherax you can create a php page that fetches the content for you from respective external url and than send a get request to that php page.

var req = new XMLHttpRequest();
req.open('GET', 'http://localhost/get_url_content.php',false);
if(req.status == 200) {
   alert(req.responseText);
}

as a php proxy you can use https://github.com/cowboy/php-simple-proxy

After lots of tests, following code works for me in Typescreipt

 export function ReplaceNewline(input: string) {
    var newline = String.fromCharCode(13, 10);
    return ReplaceAll(input, "<br>", newline.toString());
}
export function ReplaceAll(str, find, replace) {
    return str.replace(new RegExp(find, 'g'), replace);
}

Well, I didn't like any of those answers, my solution of the same problem was to add this:<div>&nbsp;</div>. So in your scheme it would look like this (more or less), no style changes were necessary in my case:

In order to export out the VAR variable first the most logical and seems working way is to source the variable:

. ./export.bash

or

source ./export.bash

Now when echoing from main shell it works

 echo $VAR
HELLO, VARABLE

We will now reset VAR

export VAR=""
echo $VAR

Now we will execute a script to source the variable then unset it :

./test-export.sh 
HELLO, VARABLE
--
.

the code: cat test-export.sh

    #!/bin/bash
    # Source env variable
    source ./export.bash

    # echo out the variable in test script
    echo $VAR

    # unset the variable 
    unset VAR
    # echo a few dotted lines
    echo "---"
    # now return VAR which is blank
    echo $VAR

Here is one way

PLEASE NOTE: The exports are limited to the script that execute the exports in your main console - so as far as a cron job I would add it like the console like below... for the command part still questionable: here is how you would run in from your shell:

On your command prompt (so long as the export.bash has multiple echo values)

IFS=$'\n'; for entries in $(./export.bash); do  export $entries;  done; ./v1.sh 
HELLO THERE
HI THERE

cat v1.sh

#!/bin/bash
echo $VAR
echo $VAR1

Now so long as this is for your usage - you could make the variables available for your scripts at any time by doing a bash alias like this:

myvars ./v1.sh
HELLO THERE
HI THERE

echo $VAR

.

add this to your .bashrc

function myvars() { 
    IFS=$'\n'; 
    for entries in $(./export.bash); do  export $entries;  done; 

    "$@"; 

    for entries in $(./export.bash); do variable=$(echo $entries|awk -F"=" '{print $1}'); unset $variable;
done

}

source your bashrc file and you can do like above any time ...

Anyhow back to the rest of it..

This has made it available globally then executed the script..

simply echo it out then run export on the echo !

cat export.bash

#!/bin/bash
echo "VAR=HELLO THERE"

Now within script or your console run:

 export "$(./export.bash)"

Try:

echo $VAR
HELLO THERE

Multiple values so long as you know what you are expecting in another script using above method:

cat export.bash

#!/bin/bash
echo "VAR=HELLO THERE"
echo "VAR1=HI THERE"

cat test-export.sh

#!/bin/bash

IFS=$'\n'
for entries in $(./export.bash); do
   export $entries
done

echo "round 1"
echo $VAR
echo $VAR1

for entries in $(./export.bash); do
     variable=$(echo $entries|awk -F"=" '{print $1}');
     unset $variable
done

echo "round 2"
echo $VAR
echo $VAR1

Now the results

 ./test-export.sh 
round 1
HELLO THERE
HI THERE
round 2


.

and the final final update to auto assign read the VARIABLES:

./test-export.sh 
Round 0 - Export out then find variable name - 
Set current variable to the variable exported then echo its value
$VAR has value of HELLO THERE
$VAR1 has value of HI THERE
round 1 - we know what was exported and we will echo out known variables
HELLO THERE
HI THERE
Round 2 - We will just return the variable names and unset them 
round 3 - Now we get nothing back

The script: cat test-export.sh

#!/bin/bash

IFS=$'\n'
echo "Round 0 - Export out then find variable name - "
echo "Set current variable to the variable exported then echo its value"
for entries in $(./export.bash); do
 variable=$(echo $entries|awk -F"=" '{print $1}');
 export $entries
 eval current_variable=\$$variable
 echo "\$$variable has value of $current_variable"
done


echo "round 1 - we know what was exported and we will echo out known variables"
echo $VAR
echo $VAR1

echo "Round 2 - We will just return the variable names and unset them "
for entries in $(./export.bash); do
 variable=$(echo $entries|awk -F"=" '{print $1}');
 unset $variable
done

echo "round 3 - Now we get nothing back"
echo $VAR
echo $VAR1

For your purposes, I recommend using SVG, since you get DOM events, like mouse handling, including drag and drop, included, you don't have to implement your own redraw, and you don't have to keep track of the state of your objects. Use Canvas when you have to do bitmap image manipulation and use a regular div when you want to manipulate stuff created in HTML. As to performance, you'll find that modern browsers are now accelerating all three, but that canvas has received the most attention so far. On the other hand, how well you write your javascript is critical to getting the most performance with canvas, so I'd still recommend using SVG.

Try this:

if(!$(this).is(':checked'))

demo

I would have done using just single line like

List<string> imageFiles = Directory.GetFiles(dir, "*.*", SearchOption.AllDirectories)
      .Where(file => new string[] { ".jpg", ".gif", ".png" }
      .Contains(Path.GetExtension(file)))
      .ToList();

Consider the following query:

$iId = mysql_real_escape_string("1 OR 1=1");    
$sSql = "SELECT * FROM table WHERE id = $iId";

mysql_real_escape_string() will not protect you against this. The fact that you use single quotes (' ') around your variables inside your query is what protects you against this. The following is also an option:

$iId = (int)"1 OR 1=1";
$sSql = "SELECT * FROM table WHERE id = $iId";

For anyone who looks at this today after 2 years, Visual Studio 2019 (Community edition as well) shows the references

Use JSONP.

jQuery:

$.ajax({
     url:"testserver.php",
     dataType: 'jsonp', // Notice! JSONP <-- P (lowercase)
     success:function(json){
         // do stuff with json (in this case an array)
         alert("Success");
     },
     error:function(){
         alert("Error");
     }      
});

PHP:

<?php
$arr = array("element1","element2",array("element31","element32"));
$arr['name'] = "response";
echo $_GET['callback']."(".json_encode($arr).");";
?>

The echo might be wrong, it's been a while since I've used php. In any case you need to output callbackName('jsonString') notice the quotes. jQuery will pass it's own callback name, so you need to get that from the GET params.

And as Stefan Kendall posted, $.getJSON() is a shorthand method, but then you need to append 'callback=?' to the url as GET parameter (yes, value is ?, jQuery replaces this with its own generated callback method).

Here is another solution I have just build with css grids based on the answers in here:

https://codesandbox.io/s/sweet-resonance-m733i

you can customize twitter bootstrap css file, open the bootstrap.css file on a text editor, and change the font-family with your font name and SAVE it.

OR got to http://getbootstrap.com/customize/ and make a customized twitter bootstrap

The params come from the user's browser when they request the page. For an HTTP GET request, which is the most common, the params are encoded in the url. For example, if a user's browser requested

http://www.example.com/?foo=1&boo=octopus

then params[:foo] would be "1" and params[:boo] would be "octopus".

In HTTP/HTML, the params are really just a series of key-value pairs where the key and the value are strings, but Ruby on Rails has a special syntax for making the params be a hash with hashes inside. For example, if the user's browser requested

http://www.example.com/?vote[item_id]=1&vote[user_id]=2

then params[:vote] would be a hash, params[:vote][:item_id] would be "1" and params[:vote][:user_id] would be "2".

The Ruby on Rails params are the equivalent of the $_REQUEST array in PHP.

Check out your php.ini, you can set these values there.

Here's the description in the php manual: http://php.net/manual/en/mail.configuration.php

If you want to use several different SMTP servers in your application, I recommend using a "bigger" mailing framework, p.e. Swiftmailer

You need to escape the backslash \:

println yourString.replace("\\", "/")

You don't need to instantiate an object, because yau are going to use a static variable: Console.WriteLine(Book.myInt);

I've been attempting to set the current row to the first index (dealing with primary keys). I would suggest

if(rs.absolute(1)){
    System.out.println("We have data");
} else {
    System.out.println("No data");
}

When the ResultSet is populated, it points to before the first row. When setting it to the first row (indicated by rs.absolute(1)) it will return true denoting it was successfully placed at row 1, or false if the row does not exist. We can extrapolate this to

for(int i=1; rs.absolute(i); i++){
    //Code
}

which sets the current row to position i and will fail if the row doesn't exist. This is just an alternative method to

while(rs.next()){
    //Code
}

Open a new worksheet on the related instance (Alt-F10) and run the following query

SELECT view_name, owner
FROM sys.all_views 
ORDER BY owner, view_name

select dateadd(minute, datediff(minute, 0, Date), 0),
       sum(SnapShotValue)
FROM [FRIIB].[dbo].[ArchiveAnalog]
group by dateadd(minute, datediff(minute, 0, Date), 0)

It sounds like that if you request faq.html the webserver signals your browser that the file is in UTF-8 encoding.

Check that with your browser which encoding is announced and used, please see the documentation of your browser how to do that. Every browser has this, most often accessible via the menu (to specify your preference which website's encoding should be used) and to see what the server returned, you often find this in page properties.

Then it sounds like that if you request faq.php the webserver singals your browser that the file is in some other encoding. Probably no charset/encoding is given as per default PHP configuration setting. As it's a PHP file you can most often solve this by changing the PHP configuration default_charset^Docs directive:

default_charset = "UTF-8"

Locate your php.ini on the host and edit it accordingly.

If you don't have the php.ini available, you can change this by code as well by using the ini_set^Docs function:

ini_set('default_charset', 'UTF-8');

Take care that you change this very early in your script because PHP needs to be able to send out headers to have this working, and headers can't be set any longer if they have already been send.

Manually sending the Content-Type header-line does work, too:

header('Content-Type: text/html; charset=UTF-8');

Additionally it's good practice that all the HTML pages you output have this header as well in their HTML <head> section:

<html>
  <head>
    ...
    <meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
    ...

Hope this is helpful.

This may be late, but sharing it for the new users visiting this question. To drop multiple columns actual syntax is

alter table tablename drop column col1, drop column col2 , drop column col3 ....

So for every column you need to specify "drop column" in Mysql 5.0.45.

I ran into this error sporadically and could not understand. Googling did not help.

I finally found out. I run a couple of docker containers, among them NGINX and Apache. The command at hand addresses a specific container, running Apache. As it turned out, I also have a cron job doing some heavy lifting at times running on the same container. Depending on the load this cron job puts on this container, it was not able to answer my command in a timely manner, resulting in error 52 empty reply from server or even 502 Bad Gateway.

I discovered and verified this by plain curl when I noticed that the process I investigated took less than 2 seconds and all of a sudden I got a 52 error and then a 502 error and then again less than 2 seconds - so it was definitely not my code which was unchanged. Using ps aux within the container I saw the other process running and understood.

Actually, I was bothered by 502 Bad Gateway from NGINX with long running jobs and could not fix it with the appropriate parameters, so I finally gave up and switched these things to Apache. That's why I was puzzled even more about these errors.

The remedy is simple. I just fired up some more instances of this container with docker service scale and that was it. docker load balances on its own.

Well, there is more to this as another example showed. This time I did some repetitious jobs.

I found out that after some time I ran out of memory used by PHP which cannot be reclaimed, so the process died.

Why? Having more than a dozen containers on a 8GB RAM machine, I initially thought it would be a good idea to limit RAM usage on PHP containers to 50MB.

Stupid! I forgot about it, but swarmpit gave me a hint. I call ini_set("memory_limit",-1); in the constructor of my class, but that only went as far as those 50MB.

So I removed those restrictions from my compose file. Now those containers may use up to 8GB. The process runs with Apache for hours now and it looks like the problem is solved, memory usage rising to well beyond 100MB.

Another caveat: To easily get and read debug messages, I started said process in Opera under Windows. That is fine with errors appearing soon.

However, if the last one is cared for, quite naturally the process runs and runs and memory usage in the browser builds up, eventually making my local machine unusable. So if that happens, kill this tab and the process keeps running fine.

Tried and tested this works !

Note: this only answers part of the question.

If you just want to know the maximum number of sessions allowed, then you can execute in sqlplus, as sysdba:

Assign empty value:

document.getElementById('numquest').value=null;

or, if want to clear all form fields. Just call form reset method as:

document.forms['form_name'].reset()

Instead of returning a resultsArray you return a promise for a results array and then then that on the call site - this has the added benefit of the caller knowing the function is performing asynchronous I/O. Coding concurrency in JavaScript is based on that - you might want to read this question to get a broader idea:

function resultsByName(name)
{   
    var Card = Parse.Object.extend("Card");
    var query = new Parse.Query(Card);
    query.equalTo("name", name.toString());

    var resultsArray = [];

    return query.find({});                           

}

// later
resultsByName("Some Name").then(function(results){
    // access results here by chaining to the returned promise
});

You can see more examples of using parse promises with queries in Parse's own blog post about it.

You need to add a CDATA tag inside of the script tag, unless you want to manually go through and escape all XHTML characters (e.g. & would need to become &). For example:

<script>
//<![CDATA[
var el = document.getElementById("pacman");

if (Modernizr.canvas && Modernizr.localstorage && 
    Modernizr.audio && (Modernizr.audio.ogg || Modernizr.audio.mp3)) {
  window.setTimeout(function () { PACMAN.init(el, "./"); }, 0);
} else { 
  el.innerHTML = "Sorry, needs a decent browser<br /><small>" + 
    "(firefox 3.6+, Chrome 4+, Opera 10+ and Safari 4+)</small>";
}
//]]>
</script>

If you want a minimum of 4 characters, for instance,

System.out.println(String.format("%4d", 5));
// Results in "   5", minimum of 4 characters

There's no such thing as a “good hash function” for universal hashes (ed. yes, I know there's such a thing as “universal hashing” but that's not what I meant). Depending on the context different criteria determine the quality of a hash. Two people already mentioned SHA. This is a cryptographic hash and it isn't at all good for hash tables which you probably mean.

Hash tables have very different requirements. But still, finding a good hash function universally is hard because different data types expose different information that can be hashed. As a rule of thumb it is good to consider all information a type holds equally. This is not always easy or even possible. For reasons of statistics (and hence collision), it is also important to generate a good spread over the problem space, i.e. all possible objects. This means that when hashing numbers between 100 and 1050 it's no good to let the most significant digit play a big part in the hash because for ~ 90% of the objects, this digit will be 0. It's far more important to let the last three digits determine the hash.

Similarly, when hashing strings it's important to consider all characters – except when it's known in advance that the first three characters of all strings will be the same; considering these then is a waste.

This is actually one of the cases where I advise to read what Knuth has to say in The Art of Computer Programming, vol. 3. Another good read is Julienne Walker's The Art of Hashing.

In some situations you can hide the shadow by another container. Eg, if there is a DIV above and below the DIV with the shadow, you can use position: relative; z-index: 1; on the surrounding DIVs.

You must use 'gem uninstall gem_name' to uninstall a gem.

Note that if you installed the gem system-wide (ie. sudo bundle install) then you may need to specify the binary directory using the -n option, to ensure binaries belonging to the gem are removed. For example

sudo gem uninstall gem_name  -n /usr/lib/ruby/gems/1.9.1/bin

This one will calculate a HashCode for each object, optimized for string, number and virtually anything that has a getHashCode function. For the rest it assigns a new reference number.

(function() {
  var __gRefID = 0;
  window.getHashCode = function(ref)
  {
      if (ref == null) { throw Error("Unable to calculate HashCode on a null reference"); }

      // already cached reference id
      if (ref.hasOwnProperty("__refID")) { return ref["__refID"]; }

      // numbers are already hashcodes
      if (typeof ref === "number") { return ref; }

      // strings are immutable, so we need to calculate this every time
      if (typeof ref === "string")
      {
          var hash = 0, i, chr;
          for (i = 0; i < ref.length; i++) {
            chr = ref.charCodeAt(i);
            hash = ((hash << 5) - hash) + chr;
            hash |= 0;
          }
          return hash;
      }

      // virtual call
      if (typeof ref.getHashCode === "function") { return ref.getHashCode(); }

      // generate and return a new reference id
      return (ref["__refID"] = "ref" + __gRefID++);
  }
})();

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

Don't do this at the view level. Just set the default value to the property in your view model's constructor. Clean and simple. In your post-backs, your selected value will automatically populate the correct selection.

For example

public class MyViewModel
{
        public MyViewModel()
        {
            Gender = "Male";
        }
}

<table>_x000D_
  <tr>_x000D_
 <td><label>@Html.RadioButtonFor(i => i.Gender, "Male")Male</label></td>_x000D_
 <td><label>@Html.RadioButtonFor(i => i.Gender, "Female")Female</label></td>_x000D_
  </tr>_x000D_
 </table>

First of all if the size of the image is smaller than the container, then only "img-fluid" class will not solve your problem. you have to set the width of image to 100%, for that you can use Bootstrap class "w-100". keep in mind that "container-fluid" and "col-12" class sets left and right padding to 15px and "row" class sets left and right margin to "-15px" by default. make sure to set them to 0.

Note: "px-0" is a bootstrap class which sets left and right padding to 0 and
"mx-0" is a bootstrap class which sets left and right margin to 0

P.S. i am using Bootstrap 4.0 version.

 <div class="container-fluid px-0">
        <div class="row mx-0">
            <div class="col-12 px-0">
            <img src="images/top.jpg" class="img-fluid w-100">
            </div>
        </div>
    </div>

I'd just add that you don't need to implement a controller method for that as you can use the view-controller tag (Spring 3) in the servlet configuration file:

<mvc:view-controller path="/" view-name="/WEB-INF/jsp/index.html"/>

This is an old question, but it has no chosen answer, and I just solved this problem myself. Here's my solution:

1. Make sure you are set up to work with your Google API in the first place. See Google's list of prerequisites. I was working with Google My Business, so I also went through it's Get Started process.

2. In the OAuth 2.0 playground, Step 1 requires you to select which API you want to authenticate. Select or input as applicable for your case (in my case for Google My Business, I had to input https://www.googleapis.com/auth/plus.business.manage into the "Input your own scopes" input field). Note: this is the same as what's described in step 6 of the "Make a simple HTTP request" section of the Get Started guide.

3. Assuming successful authentication, you should get an "Access token" returned in the "Step 1's result" step in the OAuth playground. Copy this token to your clipboard.

4. Open Postman and open whichever collection you want as necessary.

5. In Postman, make sure "GET" is selected as the request type, and click on the "Authorization" tab below the request type drop-down.

6. In the Authorization "TYPE" dropdown menu, select "Bearer Token"

7. Paste your previously copied "Access Token" which you copied from the OAuth playground into the "Token" field which displays in Postman.

8. Almost there! To test if things work, put https://mybusiness.googleapis.com/v4/accounts/ into the main URL input bar in Postman and click the send button. You should get a JSON list of accounts back in the response that looks something like the following:

   
   {
       "accounts": [
           {
               "name": "accounts/REDACTED",
               "accountName": "REDACTED",
               "type": "PERSONAL",
               "state": {
                   "status": "UNVERIFIED"
               }
           },
           {
               "name": "accounts/REDACTED",
               "accountName": "REDACTED",
               "type": "LOCATION_GROUP",
               "role": "OWNER",
               "state": {
                   "status": "UNVERIFIED"
               },
               "permissionLevel": "OWNER_LEVEL"
           }
       ]
   }
   

I had a similar issue today. For some reason, my GET request was fine, but PUT request was failing for my WCF WebHttp Service

Adding the following to the Web.config solved the issue

 <system.web>
  <authentication mode="Forms" />
 </system.web>

Microsoft explains it in the KB305703 article on How to start the default Internet browser programmatically by using Visual C#.

I initially avoided turning on logging to monitor PDO because I thought that it would be a hassle but it is not hard at all. You don't need to reboot MySQL (after 5.1.9):

Execute this SQL in phpMyAdmin or any other environment where you may have high db privileges:

SET GLOBAL general_log = 'ON';

In a terminal, tail your log file. Mine was here:

>sudo tail -f /usr/local/mysql/data/myMacComputerName.log

You can search for your mysql files with this terminal command:

>ps auxww|grep [m]ysqld

I found that PDO escapes everything, so you can't write

$dynamicField = 'userName';
$sql = "SELECT * FROM `example` WHERE `:field` = :value";
$this->statement = $this->db->prepare($sql);
$this->statement->bindValue(':field', $dynamicField);
$this->statement->bindValue(':value', 'mick');
$this->statement->execute();

Because it creates:

SELECT * FROM `example` WHERE `'userName'` = 'mick' ;

Which did not create an error, just an empty result. Instead I needed to use

$sql = "SELECT * FROM `example` WHERE `$dynamicField` = :value";

to get

SELECT * FROM `example` WHERE `userName` = 'mick' ;

When you are done execute:

SET GLOBAL general_log = 'OFF';

or else your logs will get huge.

Note this isn't at heart a question about JComboBox, but about any collection that can include multiple types of objects. The same could be said for "How do I get a String out of a List?" or "How do I get a String out of an Object[]?"

Implementation 1 returns the magnitude of the vector that would result from a regular 3D cross product of the input vectors, taking their Z values implicitly as 0 (i.e. treating the 2D space as a plane in the 3D space). The 3D cross product will be perpendicular to that plane, and thus have 0 X & Y components (thus the scalar returned is the Z value of the 3D cross product vector).

Note that the magnitude of the vector resulting from 3D cross product is also equal to the area of the parallelogram between the two vectors, which gives Implementation 1 another purpose. In addition, this area is signed and can be used to determine whether rotating from V1 to V2 moves in an counter clockwise or clockwise direction. It should also be noted that implementation 1 is the determinant of the 2x2 matrix built from these two vectors.

Implementation 2 returns a vector perpendicular to the input vector still in the same 2D plane. Not a cross product in the classical sense but consistent in the "give me a perpendicular vector" sense.

Note that 3D euclidean space is closed under the cross product operation--that is, a cross product of two 3D vectors returns another 3D vector. Both of the above 2D implementations are inconsistent with that in one way or another.

Hope this helps...

See this link. It shows you how to dynamically create variables in PowerShell.

Here is the basic idea:

Use New-Variable and Get-Variable,

for ($i=1; $i -le 5; $i++)
{
    New-Variable -Name "var$i" -Value $i
    Get-Variable -Name "var$i" -ValueOnly
}

(It is taken from the link provided, and I don't take credit for the code.)

you need only set default value to parameters(you do not need the Route attribute):

public IHttpActionResult Get(string apc = null, string xpc = null, int? sku = null)
{ ... }

A short and sweet solution, using ES6:

document.querySelectorAll('.input')
      .forEach(input => input.addEventListener('focus', this.onInputFocus));

The reason of why your code throws an UnboundLocalError is already well explained in other answers.

But it seems to me that you're trying to build something that works like itertools.count().

So why don't you try it out, and see if it suits your case:

>>> from itertools import count
>>> counter = count(0)
>>> counter
count(0)
>>> next(counter)
0
>>> counter
count(1)
>>> next(counter)
1
>>> counter
count(2)

Here are a few options for changing text / label sizes

library(ggplot2)

# Example data using mtcars

a <- aggregate(mpg ~ vs + am , mtcars, function(i) round(mean(i)))

p <- ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
            geom_bar(stat="identity",position="dodge") + 
            geom_text(data = a, aes(label = mpg), 
                            position = position_dodge(width=0.9),  size=20)

The size in the geom_text changes the size of the geom_text labels.

p <- p + theme(axis.text = element_text(size = 15)) # changes axis labels

p <- p + theme(axis.title = element_text(size = 25)) # change axis titles

p <- p + theme(text = element_text(size = 10)) # this will change all text size 
                                                             # (except geom_text)

For this And why size of 10 in geom_text() is different from that in theme(text=element_text()) ?

Yes, they are different. I did a quick manual check and they appear to be in the ratio of ~ (14/5) for geom_text sizes to theme sizes.

So a horrible fix for uniform sizes is to scale by this ratio

geom.text.size = 7
theme.size = (14/5) * geom.text.size

ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
  geom_bar(stat="identity",position="dodge") + 
  geom_text(data = a, aes(label = mpg), 
            position = position_dodge(width=0.9),  size=geom.text.size) + 
  theme(axis.text = element_text(size = theme.size, colour="black")) 

This of course doesn't explain why? and is a pita (and i assume there is a more sensible way to do this)

Well it depends, if you want to bind datas, there shouldn't be any formatting in it, otherwise you can bind-html and do description.replace(/\\n/g, '<br>') not sure it's what you want though.

1. Parse the JSON

const arr = JSON.parse(json);

2. For each object in the JSON, rename the key:

obj.id = obj._id;
delete obj._id;

3. Stringify the result

All together:

function renameKey ( obj, oldKey, newKey ) {
  obj[newKey] = obj[oldKey];
  delete obj[oldKey];
}

const json = `
  [
    {
      "_id":"5078c3a803ff4197dc81fbfb",
      "email":"[email protected]",
      "image":"some_image_url",

      "name":"Name 2"
    }
  ]
`;
   
const arr = JSON.parse(json);
arr.forEach( obj => renameKey( obj, '_id', 'id' ) );
const updatedJson = JSON.stringify( arr );

console.log( updatedJson );

Now to answer the question that perhaps you should have asked, like "I'm getting 100 floats form somewhere; do I need to put them in an array or list before I find the minimum?"

Answer: No, if somewhere is a iterable, instead of doing this:

temp = []
for x in somewhere:
   temp.append(x)
answer = min(temp)

you can do this:

answer = min(somewhere)

Example:

answer = min(float(line) for line in open('floats.txt'))

int max = 50;
int min = 1;

1. Using Math.random()

double random = Math.random() * 49 + 1;
or
int random = (int )(Math.random() * 50 + 1);

This will give you value from 1 to 50 in case of int or 1.0 (inclusive) to 50.0 (exclusive) in case of double

Why?

random() method returns a random number between 0.0 and 0.9..., you multiply it by 50, so upper limit becomes 0.0 to 49.999... when you add 1, it becomes 1.0 to 50.999..., now when you truncate to int, you get 1 to 50. (thanks to @rup in comments). leepoint's awesome write-up on both the approaches.

2. Using Random class in Java.

Random rand = new Random(); 
int value = rand.nextInt(50); 

This will give value from 0 to 49.

For 1 to 50: rand.nextInt((max - min) + 1) + min;

Try changing the second parameter in the SaveAs call to Excel.XlFileFormat.xlWorkbookDefault.

When I did that, I generated an xlsx file that I was able to successfully open. (Before making the change, I could produce an xlsx file, but I was unable to open it.)

Also, I'm not sure if it matters or not, but I'm using the Excel 12.0 object library.

Most drivers support forward only resultset - so method like last, beforeFirst etc are not supported.

The first approach is suitable if you are also getting the data in the same loop - otherwise the resultSet has already been iterated and can not be used again.

In most cases the requirement is to get the number of rows a query would return without fetching the rows. Iterating through the result set to find the row count is almost same as processing the data. It is better to do another count(*) query instead.

var time = moment().toDate();  // This will return a copy of the Date that the moment uses

time.setHours(0);
time.setMinutes(0);
time.setSeconds(0);
time.setMilliseconds(0);

Might sound obvious but do you definitely have AjaxControlToolkit.dll in your bin?

I found the following worked for me in a user defined function I created. I concatenated the cell range reference and worksheet name as a string and then used in an Evaluate statement (I was using Evaluate on Sumproduct).

For example:

Function SumRange(RangeName as range)   

Dim strCellRef, strSheetName, strRngName As String

strCellRef = RangeName.Address                 
strSheetName = RangeName.Worksheet.Name & "!" 
strRngName = strSheetName & strCellRef        

Then refer to strRngName in the rest of your code.

Since no one else said it, the short-cut to compile (build) a C# app in Visual Studio Code (VSCode) is SHIFT+CTRL+B.

If you want to see the build errors (because they don't pop-up by default), the shortcut is SHIFT+CTRL+M.

(I know this question was asking for more than just the build shortcut. But I wanted to answer the question in the title, which wasn't directly answered by other answers/comments.)

Add this to your python script.

import os
os.system("exec /path/to/another/script")

This executes that command as if it were typed into the shell.
