Programs & Examples On #Event capturing

I use the CSS properties : 1) "overflow-x: auto"; 2) "overflow-y: hidden"; 3) "white-space: nowrap";

Don't forget to set a Width, both for the container and inner DIVS components. The property "white-space : nowrap" allows the inner DIVS not to drop on a different line.

Considering the following HTML:

<div class="container"> 
  <div class="inner-1"></div>
  <div class="inner-2"></div>
  <div class="inner-3"></div>
</div>

I use the following CSS to have an horizontal scroll only:

.container {
  height: 80px;
  width: 600px;
  overflow-x: auto;
  overflow-y: hidden; 
  white-space: nowrap;
}
.inner-1,.inner-2,.inner-3 {
  height: 60px;
  max-width: 250px;
 display: inline-block; /* this should fix it */
}

You can also try TFS CLI for Node.js which is a cross-platform CLI for Microsoft Team Foundation Server and Visual Studio Team Services.

Singletons are handy when you've got a lot code being run when you initialize and object. For example, when you using iBatis when you setup a persistence object it has to read all the configs, parse the maps, make sure its all correct, etc.. before getting to your code.

If you did this every time, performance would be much degraded. Using it in a singleton, you take that hit once and then all subsequent calls don't have to do it.

I installed opencv following the steps on https://docs.opencv.org/trunk/d7/d9f/tutorial_linux_install.html

Except on Step 2, use: cmake -D CMAKE_BUILD_TYPE=Release -D OPENCV_GENERATE_PKGCONFIG=YES -D CMAKE_INSTALL_PREFIX=/path/to/opencv/ ..

Then locate the opencv4.pc file, mine was in opencv/build/unix-install/

Now run: $ export PKG_CONFIG_PATH=/path/to/the/file

You can use optimizer hints

select /*+ INDEX(table_name index_name) */ from table etc...

Yes, you can store and view images in Firebase. You can use a filepicker to get the image file. Then you can host the image however you want, I prefer Amazon s3. Once the image is hosted you can display the image using the URL generated for the image.

Hope this helps.

Since in your situation you only want to notify the user with a short and simple message, a Toast would make for a better user experience.

Toast.makeText(getApplicationContext(), "Data saved", Toast.LENGTH_LONG).show();

Update: A Snackbar is recommended now instead of a Toast for Material Design apps.

If you have a more lengthy message that you want to give the reader time to read and understand, then you should use a DialogFragment. (The documentation currently recommends wrapping your AlertDialog in a fragment rather than calling it directly.)

Make a class that extends DialogFragment:

public class MyDialogFragment extends DialogFragment {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        // Use the Builder class for convenient dialog construction
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("App Title");
        builder.setMessage("This is an alert with no consequence");
        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                // You don't have to do anything here if you just 
                // want it dismissed when clicked
            }
        });

        // Create the AlertDialog object and return it
        return builder.create();
    }
}

Then call it when you need it in your activity:

DialogFragment dialog = new MyDialogFragment();
dialog.show(getSupportFragmentManager(), "MyDialogFragmentTag");

I usually construct custom objects in these loops, and then add these objects to an array that I can easily manipulate, sort, export to CSV, etc.:

# Construct an out-array to use for data export
$OutArray = @()

# The computer loop you already have
foreach ($server in $serverlist)
    {
        # Construct an object
        $myobj = "" | Select "computer", "Speed", "Regcheck"

        # Fill the object
        $myobj.computer = $computer
        $myobj.speed = $speed
        $myobj.regcheck = $regcheck

        # Add the object to the out-array
        $outarray += $myobj

        # Wipe the object just to be sure
        $myobj = $null
    }

# After the loop, export the array to CSV
$outarray | export-csv "somefile.csv"

Yes , You can use conditional statement with EJS like if else , ternary operator or even switch case also

For Example

Ternary operator : <%- role == 'Admin' ? 'Super Admin' : role == 'subAdmin' ? 'Sub Admin' : role %>

Switch Case

<% switch (role) {
case 'Admin' : %>
        Super Admin
        <% break;

case 'eventAdmin' : %>
        Event Admin
        <% break;

case 'subAdmin' : %>
        Sub Admin
        <% break;

} %>

To my knowledge the setTimeout function is called asynchronously. What you can do is wrap the entire loop within an async function and await a Promise that contains the setTimeout as shown:

var looper = async function () {
  for (var start = 1; start < 10; start++) {
    await new Promise(function (resolve, reject) {
      setTimeout(function () {
        console.log("iteration: " + start.toString());
        resolve(true);
      }, 1000);
    });
  }
  return true;
}

And then you call run it like so:

looper().then(function(){
  console.log("DONE!")
});

Please take some time to get a good understanding of asynchronous programming.

the class attribute contains disabled when the element is not clickable.

WebElement webElement = driver.findElement(By.id("elementId"));
if(!webElement.getAttribute("class").contains("disabled")){
    webElement.click();

This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.

In standard SQL one would write:

SELECT t0.foo, t1.bar
  FROM FIRST_TABLE t0
 RIGHT OUTER JOIN SECOND_TABLE t1;

Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]

Use a BinaryReader object to return a byte array from the stream like:

byte[] fileData = null;
using (var binaryReader = new BinaryReader(Request.Files[0].InputStream))
{
    fileData = binaryReader.ReadBytes(Request.Files[0].ContentLength);
}

If this is UNIX:

sort -k 2 file.txt

You can use multiple -k flags to sort on more than one column. For example, to sort by family name then first name as a tie breaker:

sort -k 2,2 -k 1,1 file.txt

Relevant options from "man sort":

-k, --key=POS1[,POS2]

start a key at POS1, end it at POS2 (origin 1)

POS is F[.C][OPTS], where F is the field number and C the character position in the field. OPTS is one or more single-letter ordering options, which override global ordering options for that key. If no key is given, use the entire line as the key.

-t, --field-separator=SEP

use SEP instead of non-blank to blank transition

I am adding this answer since programmers coming to VBA from more modern languages and searching Stack Overflow for multithreading in VBA might be unaware of a couple of native VBA approaches which sometimes help to compensate for VBA's lack of true multithreading.

If the motivation of multithreading is to have a more responsive UI that doesn't hang when long-running code is executing, VBA does have a couple of low-tech solutions that often work in practice:

1) Userforms can be made to display modelessly - which allows the user to interact with Excel while the form is open. This can be specified at runtime by setting the Userform's ShowModal property to false or can be done dynamically as the from loads by putting the line

UserForm1.Show vbModeless

in the user form's initialize event.

2) The DoEvents statement. This causes VBA to cede control to the OS to execute any events in the events queue - including events generated by Excel. A typical use-case is updating a chart while code is executing. Without DoEvents the chart won't be repainted until after the macro is run, but with Doevents you can create animated charts. A variation of this idea is the common trick of creating a progress meter. In a loop which is to execute 10,000,000 times (and controlled by the loop index i ) you can have a section of code like:

If i Mod 10000 = 0 Then
    UpdateProgressBar(i) 'code to update progress bar display
    DoEvents
End If

None of this is multithreading -- but it might be an adequate kludge in some cases.

class Student(object):
    name = ""
    age = 0
    major = ""

    # The class "constructor" - It's actually an initializer 
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

def make_student(name, age, major):
    student = Student(name, age, major)
    return student

Note that even though one of the principles in Python's philosophy is "there should be one—and preferably only one—obvious way to do it", there are still multiple ways to do this. You can also use the two following snippets of code to take advantage of Python's dynamic capabilities:

class Student(object):
    name = ""
    age = 0
    major = ""

def make_student(name, age, major):
    student = Student()
    student.name = name
    student.age = age
    student.major = major
    # Note: I didn't need to create a variable in the class definition before doing this.
    student.gpa = float(4.0)
    return student

I prefer the former, but there are instances where the latter can be useful – one being when working with document databases like MongoDB.

This code is very easy to upload file by php. In this code I am performing uploading task in same page that mean our html and php both code resides in the same file. This code generates new name of image name.

first of all see the html code

<form action="index.php" method="post" enctype="multipart/form-data">
 <input type="file" name="banner_image" >
 <input type="submit" value="submit">
 </form>

now see the php code

<?php
$image_name=$_FILES['banner_image']['name'];
       $temp = explode(".", $image_name);
        $newfilename = round(microtime(true)) . '.' . end($temp);
       $imagepath="uploads/".$newfilename;
       move_uploaded_file($_FILES["banner_image"]["tmp_name"],$imagepath);
?>

If you don't have an array but you are trying to use your observable like an array even though it's a stream of objects, this won't work natively. I show how to fix this below assuming you only care about adding objects to the observable, not deleting them.

If you are trying to use an observable whose source is of type BehaviorSubject, change it to ReplaySubject then in your component subscribe to it like this:

Component

this.messages$ = this.chatService.messages$.pipe(scan((acc, val) => [...acc, val], []));

Html

<div class="message-list" *ngFor="let item of messages$ | async">

You can use Task Scheduler Managed Wrapper:

using System;
using Microsoft.Win32.TaskScheduler;

class Program
{
   static void Main(string[] args)
   {
      // Get the service on the local machine
      using (TaskService ts = new TaskService())
      {
         // Create a new task definition and assign properties
         TaskDefinition td = ts.NewTask();
         td.RegistrationInfo.Description = "Does something";

         // Create a trigger that will fire the task at this time every other day
         td.Triggers.Add(new DailyTrigger { DaysInterval = 2 });

         // Create an action that will launch Notepad whenever the trigger fires
         td.Actions.Add(new ExecAction("notepad.exe", "c:\\test.log", null));

         // Register the task in the root folder
         ts.RootFolder.RegisterTaskDefinition(@"Test", td);

         // Remove the task we just created
         ts.RootFolder.DeleteTask("Test");
      }
   }
}

Alternatively you can use native API or go for Quartz.NET. See this for details.

bind allows-

• set the value of "this" to an specific object. This becomes very helpful as sometimes this is not what is intended.
• reuse methods
• curry a function

For example, you have a function to deduct monthly club fees

function getMonthlyFee(fee){
  var remaining = this.total - fee;
  this.total = remaining;
  return this.name +' remaining balance:'+remaining;
}

Now you want to reuse this function for a different club member. Note that the monthly fee will vary from member to member.

Let's imagine Rachel has a balance of 500, and a monthly membership fee of 90.

var rachel = {name:'Rachel Green', total:500};

Now, create a function that can be used again and again to deduct the fee from her account every month

//bind
var getRachelFee = getMonthlyFee.bind(rachel, 90);
//deduct
getRachelFee();//Rachel Green remaining balance:410
getRachelFee();//Rachel Green remaining balance:320

Now, the same getMonthlyFee function could be used for another member with a different membership fee. For Example, Ross Geller has a 250 balance and a monthly fee of 25

var ross = {name:'Ross Geller', total:250};
//bind
var getRossFee = getMonthlyFee.bind(ross, 25);
//deduct
getRossFee(); //Ross Geller remaining balance:225
getRossFee(); //Ross Geller remaining balance:200

Microsoft SQL Server for instance, Schemas refer to a single user and is another level of a container in the order of indicating the server, database, schema, tables, and objects.

For example, when you are intending to update dbo.table_a and the syntax isn't full qualified such as UPDATE table.a the DBMS can't decide to use the intended table. Essentially by default the DBMS will utilize myuser.table_a

Just:

rm $(ls -I "*.txt" ) #Deletes file type except *.txt

Or:

rm $(ls -I "*.txt" -I "*.pdf" ) #Deletes file types except *.txt & *.pdf

Did the same thing for another quetion here

The query will be :

SELECT GROUP_CONCAT(lv SEPARATOR ',') FROM (
  SELECT @pv:=(
    SELECT GROUP_CONCAT(id SEPARATOR ',')
    FROM table WHERE parent_id IN (@pv)
  ) AS lv FROM table 
  JOIN
  (SELECT @pv:=1)tmp
  WHERE parent_id IN (@pv)
) a;

So i finally figured out how to do this. The basic idea is that you have the token you get the first time you ask for authentication. This first token has a refresh token. The first original token expires after an hour. After an hour you have to use the refresh token from the first token to get a new usable token. You use $client->refreshToken($refreshToken) to retrieve a new token. I will call this "temp token." You need to store this temp token as well because after an hour it expires as well and note it does not have a refresh token associated with it. In order to get a new temp token you need to use the method you used before and use the first token's refreshtoken. I have attached code below, which is ugly, but im new at this...

//pull token from database
$tokenquery="SELECT * FROM token WHERE type='original'";
$tokenresult = mysqli_query($cxn,$tokenquery);
if($tokenresult!=0)
{
    $tokenrow=mysqli_fetch_array($tokenresult);
    extract($tokenrow);
}
$time_created = json_decode($token)->created;
$t=time();
$timediff=$t-$time_created;
echo $timediff."<br>";
$refreshToken= json_decode($token)->refresh_token;


//start google client note:
$client = new Google_Client();
$client->setApplicationName('');
$client->setScopes(array());
$client->setClientId('');
$client->setClientSecret('');
$client->setRedirectUri('');
$client->setAccessType('offline');
$client->setDeveloperKey('');

//resets token if expired
if(($timediff>3600)&&($token!=''))
{
    echo $refreshToken."</br>";
    $refreshquery="SELECT * FROM token WHERE type='refresh'";
    $refreshresult = mysqli_query($cxn,$refreshquery);
    //if a refresh token is in there...
    if($refreshresult!=0)
    {
        $refreshrow=mysqli_fetch_array($refreshresult);
        extract($refreshrow);
        $refresh_created = json_decode($token)->created;
        $refreshtimediff=$t-$refresh_created;
        echo "Refresh Time Diff: ".$refreshtimediff."</br>";
        //if refresh token is expired
        if($refreshtimediff>3600)
        {
            $client->refreshToken($refreshToken);
        $newtoken=$client->getAccessToken();
        echo $newtoken."</br>";
        $tokenupdate="UPDATE token SET token='$newtoken' WHERE type='refresh'";
        mysqli_query($cxn,$tokenupdate);
        $token=$newtoken;
        echo "refreshed again";
        }
        //if the refresh token hasn't expired, set token as the refresh token
        else
        {
        $client->setAccessToken($token);
           echo "use refreshed token but not time yet";
        }
    }
    //if a refresh token isn't in there...
    else
    {
        $client->refreshToken($refreshToken);
        $newtoken=$client->getAccessToken();
        echo $newtoken."</br>";
        $tokenupdate="INSERT INTO token (type,token) VALUES ('refresh','$newtoken')";
        mysqli_query($cxn,$tokenupdate);
        $token=$newtoken;
        echo "refreshed for first time";
    }      
}

//if token is still good.
if(($timediff<3600)&&($token!=''))
{
    $client->setAccessToken($token);
}

$service = new Google_DfareportingService($client);

You could use the following:

mydiv.style.display === 'block' = (mydiv.style.display === 'block' ? 'none' : 'block');

Restore ownership of the user's npm related folders, to the current user, like this:

sudo chown -R $USER:$GROUP ~/.npm
sudo chown -R $USER:$GROUP ~/.config

Yes, although it's full of gotchas, since JPA is a bit peculiar. It's very much worth reading the documentation on injecting JPA EntityManager and EntityManagerFactory, without explicit Spring dependencies in your code:

http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/orm.html#orm-jpa

This allows you to either inject the EntityManagerFactory, or else inject a thread-safe, transactional proxy of an EntityManager directly. The latter makes for simpler code, but means more Spring plumbing is required.

I had this problem where I want a controller to end with a message such as 'Thanks for that form' and generic 'not found etc'. I do this under views->message->message_v.php

<?php
    $title = "Message";
    $this->load->view('templates/message_header', array("title" => $title));
?>
<h1>Message</h1>
<?php echo $msg_text; ?>
<h2>Thanks</h2>
<?php $this->load->view('templates/message_footer'); ?>

which allows me to change message rendering site wide in that single file for any thing that calls

$this->load->view("message/message_v", $data);

For anyone still looking for an easy solution in IE 6. I created a plugin that handles the IE 6 position: fixed problem and is very easy to use: http://www.fixedie.com/

I wrote it in an attempt to mimic the simplicity of belatedpng, where the only changes necessary are adding the script and invoking it.

This still appears to be an issue, causing package installations to be aborted with warnings about optional packages no being installed because of "Unsupported platform".

The problem relates to the "shrinkwrap" or package-lock.json which gets persisted after every package manager execution. Subsequent attempts keep failing as this file is referenced instead of package.json.

Adding these options to the npm install command should allow packages to install again.

   --no-optional argument will prevent optional dependencies from being installed.

   --no-shrinkwrap argument, which will ignore an available package lock or
                   shrinkwrap file and use the package.json instead.

   --no-package-lock argument will prevent npm from creating a package-lock.json file.

The complete command looks like this:

    npm install --no-optional --no-shrinkwrap --no-package-lock

nJoy!

I have read out very clear definitions for these terms.

Protected : Access is limited to within the class definition and any class that inherits from the class. The type or member can be accessed only by code in the same class or struct or in a class that is derived from that class.

Internal : Access is limited to exclusively to classes defined within the current project assembly. The type or member can be accessed only by code in same class.

Protected-Internal : Access is limited to current assembly or types derived from containing class.

This seems to be a little buggy in Pandas 0.23.4?

If there are np.nan values then this will throw an error as expected:

df['col'] = df['col'].astype(np.int64)

But doesn't change any values from float to int as I would expect if "ignore" is used:

df['col'] = df['col'].astype(np.int64,errors='ignore') 

It worked if I first converted np.nan:

df['col'] = df['col'].fillna(0).astype(np.int64)
df['col'] = df['col'].astype(np.int64)

Now I can't figure out how to get null values back in place of the zeroes since this will convert everything back to float again:

df['col']  = df['col'].replace(0,np.nan)

Though you may prefer the pure Python solution provided by the python-daemon module, there is a daemon(3) function in libc -- at least, on BSD and Linux -- which will do the right thing.

Calling it from python is easy:

import ctypes

ctypes.CDLL(None).daemon(0, 0) # Read the man-page for the arguments' meanings

The only remaining thing to do is creation (and locking) of the PID-file. But that you can handle yourself...

pip uninstall pip will work  

You can set the figure size if you explicitly create the figure with

plt.figure(figsize=(3,4))

You need to set figure size before calling plt.plot() To change the format of the saved figure just change the extension in the file name. However, I don't know if any of matplotlib backends support tiff

For Python3 it is required to use BytesIO:

from io import BytesIO
from PIL import Image, ImageDraw

image = Image.new("RGB", (300, 50))
draw = ImageDraw.Draw(image)
draw.text((0, 0), "This text is drawn on image")

byte_io = BytesIO()

image.save(byte_io, 'PNG')

Bergi's solution works nicely when fs is promise based. You can use bluebird, fs-extra or fs-promise for this.

However, solution for node's native fs libary is as follows:

const result = await Promise.all(filePaths
    .map( async filePath => {
      const fileContents = await getAssetFromCache(filePath, async function() {

        // 1. Wrap with Promise    
        // 2. Return the result of the Promise
        return await new Promise((res, rej) => {
          fs.readFile(filePath, 'utf8', function(err, data) {
            if (data) {
              res(data);
            }
          });
        });
      });

      return fileContents;
    }));

Note: require('fs') compulsorily takes function as 3rd arguments, otherwise throws error:

TypeError [ERR_INVALID_CALLBACK]: Callback must be a function

Following Macro can also be used to accomplish your task.

Mike; Everytime I need to modify an XML document I work it this way:

//Here is the variable with which you assign a new value to the attribute
string newValue = string.Empty;
XmlDocument xmlDoc = new XmlDocument();

xmlDoc.Load(xmlFile);

XmlNode node = xmlDoc.SelectSingleNode("Root/Node/Element");
node.Attributes[0].Value = newValue;

xmlDoc.Save(xmlFile);

//xmlFile is the path of your file to be modified

I hope you find it useful

You can wrap the inputs in col-* classes

<form name="registration_form" id="registration_form" class="form-horizontal">
     <div class="form-group">
           <div class="col-sm-6">
             <label for="firstname" class="sr-only"></label>
             <input id="firstname" class="form-control input-group-lg reg_name" type="text" name="firstname" title="Enter first name" placeholder="First name">
           </div>       
           <div class="col-sm-6">
             <label for="lastname" class="sr-only"></label>
             <input id="lastname" class="form-control input-group-lg reg_name" type="text" name="lastname" title="Enter last name" placeholder="Last name">
           </div>
    </div><!--/form-group-->

    <div class="form-group">
        <div class="col-sm-12">
          <label for="username" class="sr-only"></label>
          <input id="username" class="form-control input-group-lg" type="text" autocapitalize="off" name="username" title="Enter username" placeholder="Username">
        </div>
    </div><!--/form-group-->

    <div class="form-group">
        <div class="col-sm-12">
        <label for="password" class="sr-only"></label>
        <input id="password" class="form-control input-group-lg" type="password" name="password" title="Enter password" placeholder="Password">
        </div>
    </div><!--/form-group-->
 </form>

for (int i = 0; i < list.size(); i++) {
        if (i < list.size() - 1) {
            if (list.get(i) > list.get(i + 1)) {
                int j = list.get(i);
                list.remove(i);
                list.add(i, list.get(i));
                list.remove(i + 1);
                list.add(j);
                i = -1;
            }
        }
    }

As @Felix Kling suggested use action='store_true':

>>> from argparse import ArgumentParser
>>> p = ArgumentParser()
>>> _ = p.add_argument('-f', '--foo', action='store_true')
>>> args = p.parse_args()
>>> args.foo
False
>>> args = p.parse_args(['-f'])
>>> args.foo
True

Since there's no Request context in the pipeline during app start anymore, I can't imagine there's any way to guess what server/port the next actual request might come in on. You have to so it on Begin_Session.

Here's what I'm using when not in Classic Mode. The overhead is negligible.

/// <summary>
/// Class is called only on the first request
/// </summary>
private class AppStart
{
    static bool _init = false;
    private static Object _lock = new Object();

    /// <summary>
    /// Does nothing after first request
    /// </summary>
    /// <param name="context"></param>
    public static void Start(HttpContext context)
    {
        if (_init)
        {
            return;
        }
        //create class level lock in case multiple sessions start simultaneously
        lock (_lock)
        {
            if (!_init)
            {
                string server = context.Request.ServerVariables["SERVER_NAME"];
                string port = context.Request.ServerVariables["SERVER_PORT"];
                HttpRuntime.Cache.Insert("basePath", "http://" + server + ":" + port + "/");
                _init = true;
            }
        }
    }
}

protected void Session_Start(object sender, EventArgs e)
{
    //initializes Cache on first request
    AppStart.Start(HttpContext.Current);
}

In order to achieve validation when both inputs change, I use the following code (which was a combination of all others other answers):

angular.module('app.directives')
.directive('passwordVerify', [function () {
    return {
        require: '?ngModel',
        restrict: 'A',
        scope: {
            origin: '=passwordVerify'
        },
        link: function (scope, element, attrs, ctrl) {
            if(!ctrl) {
                return;
            }

            function validate(value) {
                ctrl.$setValidity('passwordMatch', scope.origin === value);
                return value;
            }

            ctrl.$parsers.unshift(validate);

            scope.$watch('origin', function(value) {
                validate(ctrl.$viewValue);
            });
        }
    };
}]);

const setTimeoutAsync = (cb, delay) =>
  new Promise((resolve) => {
    setTimeout(() => {
      resolve(cb());
    }, delay);
  });

We can pass custom 'cb fxn' like this one

I think you actually want this:

>>> from subprocess import *
>>> command_stdout = Popen(['ls', '-l'], stdout=PIPE).communicate()[0]
>>> command_text = command_stdout.decode(encoding='windows-1252')

Aaron's answer was correct, except that you need to know which encoding to use. And I believe that Windows uses 'windows-1252'. It will only matter if you have some unusual (non-ASCII) characters in your content, but then it will make a difference.

By the way, the fact that it does matter is the reason that Python moved to using two different types for binary and text data: it can't convert magically between them, because it doesn't know the encoding unless you tell it! The only way YOU would know is to read the Windows documentation (or read it here).

I recommend: Twisted (http://twistedmatrix.com)

an event-driven networking engine written in Python and licensed under the open source MIT license.

It's cross-platform and was preinstalled on OS X 10.5 to 10.12. Amongst other things you can start up a simple web server in the current directory with:

twistd -no web --path=.

Details

Explanation of Options (see twistd --help for more):

-n, --nodaemon       don't daemonize, don't use default umask of 0077
-o, --no_save        do not save state on shutdown

"web" is a Command that runs a simple web server on top of the Twisted async engine. It also accepts command line options (after the "web" command - see twistd web --help for more):

  --path=             <path> is either a specific file or a directory to be
                      set as the root of the web server. Use this if you
                      have a directory full of HTML, cgi, php3, epy, or rpy
                      files or any other files that you want to be served up
                      raw.

There are also a bunch of other commands such as:

conch            A Conch SSH service.
dns              A domain name server.
ftp              An FTP server.
inetd            An inetd(8) replacement.
mail             An email service
... etc

Installation

Ubuntu

sudo apt-get install python-twisted-web (or python-twisted for the full engine)

Mac OS-X (comes preinstalled on 10.5 - 10.12, or is available in MacPorts and through Pip)

sudo port install py-twisted

Windows

installer available for download at http://twistedmatrix.com/

HTTPS

Twisted can also utilise security certificates to encrypt the connection. Use this with your existing --path and --port (for plain HTTP) options.

twistd -no web -c cert.pem -k privkey.pem --https=4433

The only way I know is by creating a Windows shortcut to the batch file and then changing its properties to run minimized by default.

Here is the crisp answer:

public String sendSMS(String phone, String token) {
    WebClient webClient = WebClient.create(smsServiceUrl);

    SMSRequest smsRequest = new SMSRequest();
    smsRequest.setMessage(token);
    smsRequest.setPhoneNo(phone);
    smsRequest.setTokenId(smsServiceTokenId);

    Mono<String> response = webClient.post()
          .uri(smsServiceEndpoint)
          .header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
          .body(Mono.just(smsRequest), SMSRequest.class)
          .retrieve().bodyToMono(String.class);

    String deliveryResponse = response.block();
    if (deliveryResponse.equalsIgnoreCase("success")) {
      return deliveryResponse;
    }
    return null;
}

const
    start = 0,
    more = 1,
    pass = 2,
    loop = 3,
    skip = 4,
    done = 5;

var label = start;


while (true){
    var goTo = null;
    switch (label){
        case start:
            console.log('start');
        case more:
            console.log('more');
        case pass:
            console.log('pass');
        case loop:
            console.log('loop');
            goTo = pass; break;
        case skip:
            console.log('skip');
        case done:
            console.log('done');

    }
    if (goTo == null) break;
    label = goTo;
}

According to the documentation:

Field.choices

An iterable (e.g., a list or tuple) consisting itself of iterables of exactly two items (e.g. [(A, B), (A, B) ...]) to use as choices for this field. If this is given, the default form widget will be a select box with these choices instead of the standard text field.

The first element in each tuple is the actual value to be stored, and the second element is the human-readable name.

So, your code is correct, except that you should either define variables JANUARY, FEBRUARY etc. or use calendar module to define MONTH_CHOICES:

import calendar
...

class MyModel(models.Model):
    ...

    MONTH_CHOICES = [(str(i), calendar.month_name[i]) for i in range(1,13)]

    month = models.CharField(max_length=9, choices=MONTH_CHOICES, default='1')

Although it might look out of topic nobody bothered to check the ERRORLEVEL. When I used your suggestions I tried to check for errors straight after the MSI installation. I made it fail on purpose and noticed that on the command line all works beautifully whilst in a batch file msiexec dosn't seem to set errors. Tried different things there like

• Using start /wait
• Using !ERRORLEVEL! variable instead of %ERRORLEVEL%
• Using SetLocal EnableDelayedExpansion

Nothing works and what mostly annoys me it's the fact that it works in the command line.

You use the sql%rowcount variable.

You need to call it straight after the statement which you need to find the affected row count for.

For example:

set serveroutput ON; 
DECLARE 
    i NUMBER; 
BEGIN 
    UPDATE employees 
    SET    status = 'fired' 
    WHERE  name LIKE '%Bloggs'; 
    i := SQL%rowcount; 
    --note that assignment has to precede COMMIT
    COMMIT; 
    dbms_output.Put_line(i); 
END; 

If you want to force the issue, you can do:

git reset --hard c14809fafb08b9e96ff2879999ba8c807d10fb07

send you back to how your git clone looked like at the time of the checkin

Try below code

    String dateStr = "Jul 27, 2011 8:35:29 PM";
    DateFormat readFormat = new SimpleDateFormat( "MMM dd, yyyy hh:mm:ss aa");
    DateFormat writeFormat = new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss");
    Date date = null;
    try {
       date = readFormat.parse( dateStr );
    } catch ( ParseException e ) {
        e.printStackTrace();
    }

    String formattedDate = "";
    if( date != null ) {
    formattedDate = writeFormat.format( date );
    }

    System.out.println(formattedDate);

Good Luck!!!

Check for various formats.

I caught this error a few days ago.

IN my case it was because I was using a Transaction on a Singleton.

.Net does not work well with Singleton as stated above.

My solution was this:

public class DbHelper : DbHelperCore
{
    public DbHelper()
    {
        Connection = null;
        Transaction = null;
    }

    public static DbHelper instance
    {
        get
        {
            if (HttpContext.Current is null)
                return new DbHelper();
            else if (HttpContext.Current.Items["dbh"] == null)
                HttpContext.Current.Items["dbh"] = new DbHelper();

            return (DbHelper)HttpContext.Current.Items["dbh"];
        }
    }

    public override void BeginTransaction()
    {
        Connection = new SqlConnection(Entity.Connection.getCon);
        if (Connection.State == System.Data.ConnectionState.Closed)
            Connection.Open();
        Transaction = Connection.BeginTransaction();
    }
}

I used HttpContext.Current.Items for my instance. This class DbHelper and DbHelperCore is my own class

public static class GenericExtension
{
    public static T? ConvertToNullable<T>(this String s) where T : struct 
    {
        try
        {
            return (T?)TypeDescriptor.GetConverter(typeof(T)).ConvertFrom(s);
        }
        catch (Exception)
        {
            return null;
        }
    }
}

The reseting input file is on very single

$('input[type=file]').val(null);

If you bind reset the file in change other field of the form, or load form with ajax.

This example is applicable

selector for example is $('input[type=text]') or any element of the form

event click, change, or any event

$('body').delegate('event', 'selector', function(){
     $('input[type=file]').val(null) ;
});

Using mod_rewrite is not the recommended way instead use virtual host and redirect.

In case, if you are inclined to do using mod_rewrite:

RewriteEngine On
# This will enable the Rewrite capabilities

RewriteCond %{HTTPS} !=on
# This checks to make sure the connection is not already HTTPS

RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]
# This rule will redirect users from their original location, to the same 
location but using HTTPS.
# i.e.  http://www.example.com/foo/ to https://www.example.com/foo/
# The leading slash is made optional so that this will work either in
# httpd.conf or .htaccess context

Reference: Httpd Wiki - RewriteHTTPToHTTPS

If you are looking for a 301 Permanent Redirect, then redirect flag should be as,

 R=301

so the RewriteRule will be like,

RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R=301,L]

for example if you want to get EMAIL ADDRESS from config->store email addresses. You can specify from wich store you will want the address:

$store=Mage::app()->getStore()->getStoreId(); 
/* Sender Name */
Mage::getStoreConfig('trans_email/ident_general/name',$store); 
/* Sender Email */
Mage::getStoreConfig('trans_email/ident_general/email',$store);

• Use screen: Start screen, start your script, press Ctrl+A, D. Reattach with screen -r.

• Make a script that takes your "1" as a parameter, run nohup yourscript:

  #!/bin/bash
  (time bash executeScript $1 input fileOutput $> scrOutput) &> timeUse.txt
  

To complete @thecatontheflat answer I would recommend to also wrap your action inside of a try … catch block. This will prevent your JSON endpoint from breaking on exceptions. Here's the skeleton I use:

public function someAction()
{
    try {

        // Your logic here...

        return new JsonResponse([
            'success' => true,
            'data'    => [] // Your data here
        ]);

    } catch (\Exception $exception) {

        return new JsonResponse([
            'success' => false,
            'code'    => $exception->getCode(),
            'message' => $exception->getMessage(),
        ]);

    }
}

This way your endpoint will behave consistently even in case of errors and you will be able to treat them right on a client side.

pathinfo is what you're looking for

PHP.net

$file_parts = pathinfo($filename);

switch($file_parts['extension'])
{
    case "jpg":
    break;

    case "exe":
    break;

    case "": // Handle file extension for files ending in '.'
    case NULL: // Handle no file extension
    break;
}

You could try setting up a filter using the unicodedata.category() function:

import unicodedata
printable = {'Lu', 'Ll'}
def filter_non_printable(str):
  return ''.join(c for c in str if unicodedata.category(c) in printable)

See Table 4-9 on page 175 in the Unicode database character properties for the available categories

One more way to add view from Activity

ViewGroup rootLayout = findViewById(android.R.id.content);
rootLayout.addView(view);

dist = sqrt( (x2 - x1)**2 + (y2 - y1)**2 )

As others have pointed out, you can also use the equivalent built-in math.hypot():

dist = math.hypot(x2 - x1, y2 - y1)

Best command is: tree -fi

-f print the full path prefix for each file
-i don't print indentations

e.g.

$ tree -fi
.
./README.md
./node_modules
./package.json
./src
./src/datasources
./src/datasources/bookmarks.js
./src/example.json
./src/index.js
./src/resolvers.js
./src/schema.js

In order to use the files but not the links, you have to remove > from your output:

tree -fi |grep -v \>

If you want to know the nature of each file, (to read only ASCII files for example) with two whiles:

tree -fi | \
grep -v \> | \
while read first ; do 
    file ${first}
done | \
while read second; do 
    echo ${second} | grep ASCII
done

JSON is a format that encodes objects in a string. Serialization means to convert an object into that string, and deserialization is its inverse operation (convert string -> object).

When transmitting data or storing them in a file, the data are required to be byte strings, but complex objects are seldom in this format. Serialization can convert these complex objects into byte strings for such use. After the byte strings are transmitted, the receiver will have to recover the original object from the byte string. This is known as deserialization.

Say, you have an object:

{foo: [1, 4, 7, 10], bar: "baz"}

serializing into JSON will convert it into a string:

'{"foo":[1,4,7,10],"bar":"baz"}'

which can be stored or sent through wire to anywhere. The receiver can then deserialize this string to get back the original object. {foo: [1, 4, 7, 10], bar: "baz"}.

See Creating a shared and static library with the gnu compiler [gcc]

gcc -c -o out.o out.c

-c means to create an intermediary object file, rather than an executable.

ar rcs libout.a out.o

This creates the static library. r means to insert with replacement, c means to create a new archive, and s means to write an index. As always, see the man page for more info.

I know this is an old post but its relevant to what I'm working on currently.

What I'm aiming to do is create next/previous page buttons at the top of a html page, and say I'm on 'book.html', with the current 'display' ID content being 'page-1.html' through ajax, if i click the 'next' button it will load 'page-2.html' through ajax, WITHOUT reloading the page.

How would I go about doing this through AJAX as I have seen many examples but most of them are completely different, and most examples of using AJAX are for WordPress forms and stuff.

Currently using the below line will open the entire page, I want to know the best way to go about using AJAX instead if possible :) window.location(url);

I'm incorportating the below code as an example:

var i = 1;
var url = "pages/page-" + i + ".html";

    function incPage() {
    if (i < 10) {
        i++;
        window.location = url; 
        //load next page in body using AJAX request

    } else if (i = 10) {
        i = 0;
    }
    document.getElementById("display").innerHTML = i;
}

function decPage() {
    if (i > 0) {
        --i;
        window.location = url; 
        //load previous page in body using AJAX request
    } else if (i = 0) {
        i = 10;
    }
    document.getElementById("display").innerHTML = i;
}

Do this:

npm install --no-optional

For more info on this go through: https://github.com/npm/npm/issues/11632

The solution to this problem is to set the following environment variable:

VS90COMNTOOLS

For instance:

set VS90COMNTOOLS=C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools

This error can be caused by not rebooting after installing Visual Studios, or not starting a new command prompt after installing.

Also the version of Visual Studios you can use to compile the extensions may depend on the version of python you are building for.

Using imagemagick, you can try:

convert page.png page.pdf

Or for multiple images:

convert page*.png mydoc.pdf

For those early adapting people on the CofeeScript era, here's another equivalent for it.

val for key,val of objects

Which may be better than this because the objects can be reduced to be typed again and decreased readability.

objects[key] for key of objects

If your data has the names grouped as shown then you can use this formula in D2 copied down to get a total against the last entry for each name

=IF((A2=A3)*(B2=B3),"",SUM(C$2:C2)-SUM(D$1:D1))

See screenshot

Or you can use the more obvious solution, right in the GUI: Tools -> Messages (set verbosity to 2)...

Another great Treeview jquery plugin is http://www.jstree.com/

For an advance view you should check jquery-treetable
http://ludo.cubicphuse.nl/jquery-plugins/treeTable/doc/

You can use Query.values, Query.values

session.query(SomeModel).values('id', 'user')

If you mark a form element as required="" then novalidate="" does not help.

A way to circumvent the required validation is to disable the element.

After a bit of googling, it seems that there never was a separate redistributable for Visual C++ 2003 (7.1). At least that is what a post on the microsoft forum says.

You may however be able to extract the runtime DLLs from the VC 7.1 DST timezone update.

You can pass a variable to a function by reference. This function will be able to modify the original variable.

You can define the passage by reference in the function definition:

<?php
function changeValue(&$var)
{
    $var++;
}

$result=5;
changeValue($result);

echo $result; // $result is 6 here
?>

You could merge two queries together:

$merged = $query_one->merge($query_two);

From here (Google is your friend):

In a DTD, PCDATA and CDATA are used to assert something about the allowable content of elements and attributes, respectively. In an element's content model, #PCDATA says that the element contains (may contain) "any old text." (With exceptions as noted below.) In an attribute's declaration, CDATA is one sort of constraint you can put on the attribute's allowable values (other sorts, all mutually exclusive, include ID, IDREF, and NMTOKEN). An attribute whose allowable values are CDATA can (like PCDATA in an element) contain "any old text."

A potentially really confusing issue is that there's another "CDATA," also referred to as marked sections. A marked section is a portion of element (#PCDATA) content delimited with special strings: to close it. If you remember that PCDATA is "parsed character data," a CDATA section is literally the same thing, without the "parsed." Parsers transmit the content of a marked section to downstream applications without hiccupping every time they encounter special characters like < and &. This is useful when you're coding a document that contains lots of those special characters (like scripts and code fragments); it's easier on data entry, and easier on reading, than the corresponding entity reference.

So you can infer that the exception to the "any old text" rule is that PCDATA cannot include any of these unescaped special characters, UNLESS they fall within the scope of a CDATA marked section.

here allows is class of checkboxes on pages and var allows collects them in an array and you can check for checked true in for loop then perform the desired operation individually. Here I have set custom validity. I think it will solve your problem.

  $(".allows").click(function(){
   var allows = document.getElementsByClassName('allows');
   var chkd   = 0;  
   for(var i=0;i<allows.length;i++)
   {
       if(allows[i].checked===true)
       {
           chkd = 1;
       }else
       {

       }
   }

   if(chkd===0)
   {
       $(".allows").prop("required",true);
       for(var i=0;i<allows.length;i++)
        {
        allows[i].setCustomValidity("Please select atleast one option");
        }

   }else
   {
       $(".allows").prop("required",false);
       for(var i=0;i<allows.length;i++)
        {
        allows[i].setCustomValidity("");
        }
   }

}); 

I prefer fork + execlp for "more fine-grade" control as doron mentioned. Example code shown below.

Store you command in a char array parameters, and malloc space for the result.

int fd[2];
pipe(fd);
if ( (childpid = fork() ) == -1){
   fprintf(stderr, "FORK failed");
   return 1;
} else if( childpid == 0) {
   close(1);
   dup2(fd[1], 1);
   close(fd[0]);
   execlp("/bin/sh","/bin/sh","-c",parameters,NULL);
}
wait(NULL);
read(fd[0], result, RESULT_SIZE);
printf("%s\n",result);

it takes this command about 2 mins to return the data as there is a lot of data

Probably, Bad Design. Consider using paging here.

default connection time is 30 secs, how do I increase this

As you are facing a timeout on your command, therefore you need to increase the timeout of your sql command. You can specify it in your command like this

// Setting command timeout to 2 minutes
scGetruntotals.CommandTimeout = 120;

I think most of the important stuff has been said, but I just thought I'd add one thing: If you compile as Any CPU and run on an x64 platform, then you won't be able to load 32-bit DLL files, because your application wasn't started in WoW64, but those DLL files need to run there.

If you compile as x86, then the x64 system will run your application in WoW64, and you'll be able to load 32-bit DLL files.

So I think you should choose "Any CPU" if your dependencies can run in either environment, but choose x86 if you have 32-bit dependencies. This article from Microsoft explains this a bit:

/CLRIMAGETYPE (Specify Type of CLR Image)

Incidentally, this other Microsoft documentation agrees that x86 is usually a more portable choice:

Choosing x86 is generally the safest configuration for an app package since it will run on nearly every device. On some devices, an app package with the x86 configuration won't run, such as the Xbox or some IoT Core devices. However, for a PC, an x86 package is the safest choice and has the largest reach for device deployment. A substantial portion of Windows 10 devices continue to run the x86 version of Windows.

I would break up

public static void main(String args[])

in parts.

"public" means that main() can be called from anywhere.

"static" means that main() doesn't belong to a specific object

"void" means that main() returns no value

"main" is the name of a function. main() is special because it is the start of the program.

"String[]" means an array of String.

"args" is the name of the String[] (within the body of main()). "args" is not special; you could name it anything else and the program would work the same.

• String[] args is a collection of Strings, separated by a space, which can be typed into the program on the terminal. More times than not, the beginner isn't going to use this variable, but it's always there just in case.

I think that You have memory leaks somewhere. You can find tips to avoid leaking memory here. Also you can learn about tools to track it down here.

You could also put: (load_essentials.js:)

document.getElementById("myHead").innerHTML =_x000D_
 "<span id='headerText'>Title</span>"_x000D_
 + "<span id='headerSubtext'>Subtitle</span>";_x000D_
document.getElementById("myNav").innerHTML =_x000D_
 "<ul id='navLinks'>"_x000D_

 + "</ul>";_x000D_
document.getElementById("myFooter").innerHTML =_x000D_
 "<p id='copyright'>Copyright &copy; " + new Date().getFullYear() + " You. All"_x000D_
 + " rights reserved.</p>"_x000D_
 + "<p id='credits'>Layout by You</p>"_x000D_
 + "<p id='contact'><a href='mailto:[email protected]'>Contact Us</a> / "_x000D_
 + "<a href='mailto:[email protected]'>Report a problem.</a></p>";

<!--HTML-->_x000D_
<header id="myHead"></header>_x000D_
<nav id="myNav"></nav>_x000D_
Content_x000D_
<footer id="myFooter"></footer>_x000D_
_x000D_
<script src="load_essentials.js"></script>

According to JavaDocs, you can do this:

WebElement input = divA.findElement(By.xpath(".//input"));

How can I ask in xpath for "the div-tag that contains a span with the text 'hello world'"?

WebElement elem = driver.findElement(By.xpath("//div[span[text()='hello world']]"));

The XPath spec is a suprisingly good read on this.

This is the most elegant solution.

private void buttonLogin_Click(object sender, EventArgs e)
{
    MainForm mainForm = new MainForm();
    this.Hide();
    mainForm.ShowDialog();
    this.Close();
}

;-)

None of the previous solutions worked for me. Finally I found that the action should be coded as:

public ActionResult Index(string MyCheck = null)

and then, when checked the passed value was "on", not "true". Else, it is always null.

Hope it helps somebody!

The Saxon documentation, though a little unclear, seems to suggest that the JAXP XPath API will return false when evaluating an XPath expression if no matching nodes are found.

This IBM article mentions a return value of null when no nodes are matched.

You might need to play around with the return types a bit based on this API, but the basic idea is that you just run a normal XPath and check whether the result is a node / false / null / etc.

XPathFactory xpathFactory = XPathFactory.newInstance(NamespaceConstant.OBJECT_MODEL_SAXON);
XPath xpath = xpathFactory.newXPath();
XPathExpression expr = xpath.compile("/Consumers/Consumer/DataSources/Credit/CreditReport/AttachedXml");
Object result = expr.evaluate(doc, XPathConstants.NODE);

if ( result == null ) {
    // do something
}

You mention adding the additional include directory (C/C++|General) and additional lib dependency (Linker|Input), but have you also added the additional library directory (Linker|General)?

Including a sample error message might also help people answer the question since it's not even clear if the error is during compilation or linking.

To convert a DATE column to another format, just use TO_CHAR() with the desired format, then convert it back to a DATE type:

SELECT TO_DATE(TO_CHAR(date_column, 'DD-MM-YYYY'), 'DD-MM-YYYY') from my_table

Rather than keeping everything string-based, you should use a class which is designed to represent a file system path.

If you're using Java 7 or Java 8, you should strongly consider using java.nio.file.Path; Path.resolve can be used to combine one path with another, or with a string. The Paths helper class is useful too. For example:

Path path = Paths.get("foo", "bar", "baz.txt");

If you need to cater for pre-Java-7 environments, you can use java.io.File, like this:

File baseDirectory = new File("foo");
File subDirectory = new File(baseDirectory, "bar");
File fileInDirectory = new File(subDirectory, "baz.txt");

If you want it back as a string later, you can call getPath(). Indeed, if you really wanted to mimic Path.Combine, you could just write something like:

public static String combine(String path1, String path2)
{
    File file1 = new File(path1);
    File file2 = new File(file1, path2);
    return file2.getPath();
}

They are project files, that hold the module information and meta data.

Just add *.iml to .gitignore.

In Android Studio: Press CTRL + F9 to rebuild your project. The missing *.iml files will be generated.

There is still another way to do it, which is using a particular NamingStrategy, which can be applied to a class or a property by decorating them with [JSonObject] or [JsonProperty].

There are predefined naming strategies like CamelCaseNamingStrategy, but you can implement your own ones.

The implementation of different naming strategies can be found here: https://github.com/JamesNK/Newtonsoft.Json/tree/master/Src/Newtonsoft.Json/Serialization

Have you tried using the official JQueryUI implementation (not jQuery only) : ?

@ allows a value defined on the directive attribute to be passed to the directive's isolate scope. The value could be a simple string value (myattr="hello") or it could be an AngularJS interpolated string with embedded expressions (myattr="my_{{helloText}}"). Think of it as "one-way" communication from the parent scope into the child directive. John Lindquist has a series of short screencasts explaining each of these. Screencast on @ is here: https://egghead.io/lessons/angularjs-isolate-scope-attribute-binding

& allows the directive's isolate scope to pass values into the parent scope for evaluation in the expression defined in the attribute. Note that the directive attribute is implicitly an expression and does not use double curly brace expression syntax. This one is tougher to explain in text. Screencast on & is here: https://egghead.io/lessons/angularjs-isolate-scope-expression-binding

= sets up a two-way binding expression between the directive's isolate scope and the parent scope. Changes in the child scope are propagated to the parent and vice-versa. Think of = as a combination of @ and &. Screencast on = is here: https://egghead.io/lessons/angularjs-isolate-scope-two-way-binding

And finally here is a screencast that shows all three used together in a single view: https://egghead.io/lessons/angularjs-isolate-scope-review

There's a nodejs tool which supports json schema v4 at https://github.com/krg7880/json-schema-generator

It works either as a command line tool, or as a nodejs library:

var jsonSchemaGenerator = require('json-schema-generator'),
    obj = { some: { object: true } },
    schemaObj;

schemaObj = jsonSchemaGenerator(json);

When I got this error, it may have been because of my UPDATE syntax being wrong, but after I fixed the update query I got the same error again...so I went to the ODBC Data Source Administrator and found that my connection was read-only. After I made the connection read-write and re-connected it worked just fine.

Get image size with jQuery

function getMeta(url){
    $("<img/>",{
        load : function(){
            alert(this.width+' '+this.height);
        },
        src  : url
    });
}

Get image size with JavaScript

function getMeta(url){   
    var img = new Image();
    img.onload = function(){
        alert( this.width+' '+ this.height );
    };
    img.src = url;
}

Get image size with JavaScript (modern browsers, IE9+ )

function getMeta(url){   
    var img = new Image();
    img.addEventListener("load", function(){
        alert( this.naturalWidth +' '+ this.naturalHeight );
    });
    img.src = url;
}

Use the above simply as: getMeta( "http://example.com/img.jpg" );

psql template1

creating role on pgsql with privilege as "superuser"

CREATE ROLE username superuser;
eg. CREATE ROLE demo superuser;

Then create user

CREATE USER username; 
eg. CREATE USER demo;

Assign privilege to user

GRANT ROOT TO username;

And then enable login that user, so you can run e.g.: psql template1, from normal $ terminal:

ALTER ROLE username WITH LOGIN;

If you hide the overflow and there is a long word, you risk loosing that word, so you could go one step further and use the "word-wrap" css attribute.

Differences in SOAP versions

Both SOAP Version 1.1 and SOAP Version 1.2 are World Wide Web Consortium (W3C) standards. Web services can be deployed that support not only SOAP 1.1 but also support SOAP 1.2. Some changes from SOAP 1.1 that were made to the SOAP 1.2 specification are significant, while other changes are minor.

The SOAP 1.2 specification introduces several changes to SOAP 1.1. This information is not intended to be an in-depth description of all the new or changed features for SOAP 1.1 and SOAP 1.2. Instead, this information highlights some of the more important differences between the current versions of SOAP.

The changes to the SOAP 1.2 specification that are significant include the following updates: SOAP 1.1 is based on XML 1.0. SOAP 1.2 is based on XML Information Set (XML Infoset). The XML information set (infoset) provides a way to describe the XML document with XSD schema. However, the infoset does not necessarily serialize the document with XML 1.0 serialization on which SOAP 1.1 is based.. This new way to describe the XML document helps reveal other serialization formats, such as a binary protocol format. You can use the binary protocol format to compact the message into a compact format, where some of the verbose tagging information might not be required.

In SOAP 1.2 , you can use the specification of a binding to an underlying protocol to determine which XML serialization is used in the underlying protocol data units. The HTTP binding that is specified in SOAP 1.2 - Part 2 uses XML 1.0 as the serialization of the SOAP message infoset.

SOAP 1.2 provides the ability to officially define transport protocols, other than using HTTP, as long as the vendor conforms to the binding framework that is defined in SOAP 1.2. While HTTP is ubiquitous, it is not as reliable as other transports including TCP/IP and MQ. SOAP 1.2 provides a more specific definition of the SOAP processing model that removes many of the ambiguities that might lead to interoperability errors in the absence of the Web Services-Interoperability (WS-I) profiles. The goal is to significantly reduce the chances of interoperability issues between different vendors that use SOAP 1.2 implementations. SOAP with Attachments API for Java (SAAJ) can also stand alone as a simple mechanism to issue SOAP requests. A major change to the SAAJ specification is the ability to represent SOAP 1.1 messages and the additional SOAP 1.2 formatted messages. For example, SAAJ Version 1.3 introduces a new set of constants and methods that are more conducive to SOAP 1.2 (such as getRole(), getRelay()) on SOAP header elements. There are also additional methods on the factories for SAAJ to create appropriate SOAP 1.1 or SOAP 1.2 messages. The XML namespaces for the envelope and encoding schemas have changed for SOAP 1.2. These changes distinguish SOAP processors from SOAP 1.1 and SOAP 1.2 messages and supports changes in the SOAP schema, without affecting existing implementations. Java Architecture for XML Web Services (JAX-WS) introduces the ability to support both SOAP 1.1 and SOAP 1.2. Because JAX-RPC introduced a requirement to manipulate a SOAP message as it traversed through the run time, there became a need to represent this message in its appropriate SOAP context. In JAX-WS, a number of additional enhancements result from the support for SAAJ 1.3.

There is not difine POST AND GET method for particular android....but all here is differance

GET The GET method appends name/value pairs to the URL, allowing you to retrieve a resource representation. The big issue with this is that the length of a URL is limited (roughly 3000 char) resulting in data loss should you have to much stuff in the form on your page, so this method only works if there is a small number parameters.

What does this mean for me? Basically this renders the GET method worthless to most developers in most situations. Here is another way of looking at it: the URL could be truncated (and most likely will be give today's data-centric sites) if the form uses a large number of parameters, or if the parameters contain large amounts of data. Also, parameters passed on the URL are visible in the address field of the browser (YIKES!!!) not the best place for any kind of sensitive (or even non-sensitive) data to be shown because you are just begging the curious user to mess with it.

POST The alternative to the GET method is the POST method. This method packages the name/value pairs inside the body of the HTTP request, which makes for a cleaner URL and imposes no size limitations on the forms output, basically its a no-brainer on which one to use. POST is also more secure but certainly not safe. Although HTTP fully supports CRUD, HTML 4 only supports issuing GET and POST requests through its various elements. This limitation has held Web applications back from making full use of HTTP, and to work around it, most applications overload POST to take care of everything but resource retrieval.

Or you can just run the following command and you will see all databases of the Redis instance without firing up redis-cli:

$ redis-cli INFO | grep ^db
db0:keys=1500,expires=2
db1:keys=200000,expires=1
db2:keys=350003,expires=1

No Problem You can use onClick() function easily without using any other interference of language,

<?php
echo '<br><Button onclick="document.getElementById(';?>'modal-wrapper2'<?php echo ').style.display=';?>'block'<?php echo '" name="comment" style="width:100px; color: white;background-color: black;border-radius: 10px; padding: 4px;">Show</button>';
?>

Real shows total turn-around time for a process; while User shows the execution time for user-defined instructions and Sys is for time for executing system calls!

Real time includes the waiting time also (the waiting time for I/O etc.)

There are two possible problems:

1. AJAX is asynchronous, so json will be undefined when you return from the outer function. When the file has been loaded, the callback function will set json to some value but at that time, nobody cares anymore.

   I see that you tried to fix this with 'async': false. To check whether this works, add this line to the code and check your browser's console:

   console.log(['json', json]);
   

2. The path might be wrong. Use the same path that you used to load your script in the HTML document. So if your script is js/script.js, use js/content.json

   Some browsers can show you which URLs they tried to access and how that went (success/error codes, HTML headers, etc). Check your browser's development tools to see what happens.

You should look at compareTo function of Date class.

JavaDoc

skipUntil() with last()

skipUntil : ignore emitted items until another observable has emitted

last: emit last value from a sequence (i.e. wait until it completes then emit)

Note that anything emitted from the observable passed to skipUntil will cancel the skipping, which is why we need to add last() - to wait for the stream to complete.

main$.skipUntil(sequence2$.pipe(last()))

Official: https://rxjs-dev.firebaseapp.com/api/operators/skipUntil

Possible issue: Note that last() by itself will error if nothing is emitted. The last() operator does have a default parameter but only when used in conjunction with a predicate. I think if this situation is a problem for you (if sequence2$ may complete without emitting) then one of these should work (currently untested):

main$.skipUntil(sequence2$.pipe(defaultIfEmpty(undefined), last()))
main$.skipUntil(sequence2$.pipe(last(), catchError(() => of(undefined))

Note that undefined is a valid item to be emitted, but could actually be any value. Also note that this is the pipe attached to sequence2$ and not the main$ pipe.

Try this:

static double Evaluate(string expression) {
  var loDataTable = new DataTable();
  var loDataColumn = new DataColumn("Eval", typeof (double), expression);
  loDataTable.Columns.Add(loDataColumn);
  loDataTable.Rows.Add(0);
  return (double) (loDataTable.Rows[0]["Eval"]);
}

I currently use this statusbar settings:

set laststatus=2
set statusline=\ %f%m%r%h%w\ %=%({%{&ff}\|%{(&fenc==\"\"?&enc:&fenc).((exists(\"+bomb\")\ &&\ &bomb)?\",B\":\"\")}%k\|%Y}%)\ %([%l,%v][%p%%]\ %)

My complete .vimrc file: http://gabriev82.altervista.org/projects/vim-configuration/

It worked for me, but only with ssh key and not with username and password.

After i added the ssh key to sourcetree, i changed the settings under Tools -> Options -> SSH-Client to work with PuTTY/Plink.

I run into trouble after i added the ssh key, because i forgot to restart sourceTree. "this is necessary so that there is an instance of ssh-agent running that SourceTree can talk to with your key loaded." See here: https://answers.atlassian.com/questions/189412/sourcetree-with-gitlab-ssh-not-working

the most important thing is to analyze how roads, cities, blocks and buildings are structured. find out what all eg buildings have in common. look at photos, maps, plans and reality. if you do that you will be one step ahead of people who consider city building as a merely computer-technological matter.

next you should develop solutions on how to create that geometry in tiny, distinct steps. you have to define rules that make up a believable city. if you are into 3d modelling you have to rethink a lot of what you have learned so the computer can follow your instructions in any situation.

in order to not loose track you should set up a lot of operators that are only responsible for little parts of the whole process. that makes debugging, expanding and improving your system much easier. in the next step you should link those operators and check the results by changing parameters.

i have seen too many "city generators" that mainly consist of random-shaped boxes with some window textures on them : (

You can save your array as a json.
there is documentation for json data type: https://dev.mysql.com/doc/refman/5.7/en/json.html

1. PDO stands for PHP Data Object.
2. PDO_MYSQL is the driver that will implement the interface between the dataobject(database) and the user input (a layer under the user interface called "code behind") accessing your data object, the MySQL database.

The purpose of using this is to implement an additional layer of security between the user interface and the database. By using this layer, data can be normalized before being inserted into your data structure. (Capitals are Capitals, no leading or trailing spaces, all dates at properly formed.)

But there are a few nuances to this which you might not be aware of.

First of all, up until now, you've probably written all your queries in something similar to the URL, and you pass the parameters using the URL itself. Using the PDO, all of this is done under the user interface level. User interface hands off the ball to the PDO which carries it down field and plants it into the database for a 7-point TOUCHDOWN.. he gets seven points, because he got it there and did so much more securely than passing information through the URL.

You can also harden your site to SQL injection by using a data-layer. By using this intermediary layer that is the ONLY 'player' who talks to the database itself, I'm sure you can see how this could be much more secure. Interface to datalayer to database, datalayer to database to datalayer to interface.

And:

By implementing best practices while writing your code you will be much happier with the outcome.

Had the same problem with embeded youtube iframe (Translations were used for centering iframe element). None of the solutions above worked until tried reset css filters and magic happened.

Structure:

The other day I'd been solving the similar issue and found convenient to convert hex color string to int array [alpha, r, g, b]:

 /**
 * Hex color string to int[] array converter
 *
 * @param hexARGB should be color hex string: #AARRGGBB or #RRGGBB
 * @return int[] array: [alpha, r, g, b]
 * @throws IllegalArgumentException
 */

public static int[] hexStringToARGB(String hexARGB) throws IllegalArgumentException {

    if (!hexARGB.startsWith("#") || !(hexARGB.length() == 7 || hexARGB.length() == 9)) {

        throw new IllegalArgumentException("Hex color string is incorrect!");
    }

    int[] intARGB = new int[4];

    if (hexARGB.length() == 9) {
        intARGB[0] = Integer.valueOf(hexARGB.substring(1, 3), 16); // alpha
        intARGB[1] = Integer.valueOf(hexARGB.substring(3, 5), 16); // red
        intARGB[2] = Integer.valueOf(hexARGB.substring(5, 7), 16); // green
        intARGB[3] = Integer.valueOf(hexARGB.substring(7), 16); // blue
    } else hexStringToARGB("#FF" + hexARGB.substring(1));

    return intARGB;
}

If your IDE is IntelliJ Idea, you can forget all these headaches and store your regex into a String variable and as you copy-paste it inside the double-quote it will automatically change to a regex acceptable format.

example in Java:

String s = "\"en_usa\":[^\\,\\}]+";

now you can use this variable in your regexp or anywhere.

In my specific case of the same issue, it was caused by not having the Powershell script saved with an encoding of Windows-1252 or UFT-8 WITH BOM.

Another working solution for IE specific styling is

<html data-useragent="Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)">

And then your selector

html[data-useragent*='MSIE 10.0'] body .my-class{
        margin-left: -0.4em;
    }

I totally agree with both the question and Martin's answer :). Even in Java, reading javadoc with generics is much harder than it should be due to the extra noise. This is compounded in Scala where implicit parameters are used as in the questions's example code (while the implicits do very useful collection-morphing stuff).

I don't think its a problem with the language per se - I think its more a tooling issue. And while I agree with what Jörg W Mittag says, I think looking at scaladoc (or the documentation of a type in your IDE) - it should require as little brain power as possible to grok what a method is, what it takes and returns. There shouldn't be a need to hack up a bit of algebra on a bit of paper to get it :)

For sure IDEs need a nice way to show all the methods for any variable/expression/type (which as with Martin's example can have all the generics inlined so its nice and easy to grok). I like Martin's idea of hiding the implicits by default too.

To take the example in scaladoc...

def map[B, That](f: A => B)(implicit bf: CanBuildFrom[Repr, B, That]): That

When looking at this in scaladoc I'd like the generic block [B, That] to be hidden by default as well as the implicit parameter (maybe they show if you hover a little icon with the mouse) - as its extra stuff to grok reading it which usually isn't that relevant. e.g. imagine if this looked like...

def map(f: A => B): That

nice and clear and obvious what it does. You might wonder what 'That' is, if you mouse over or click it it could expand the [B, That] text highlighting the 'That' for example.

Maybe a little icon could be used for the [] declaration and (implicit...) block so its clear there are little bits of the statement collapsed? Its hard to use a token for it, but I'll use a . for now...

def map.(f: A => B).: That

So by default the 'noise' of the type system is hidden from the main 80% of what folks need to look at - the method name, its parameter types and its return type in nice simple concise way - with little expandable links to the detail if you really care that much.

Mostly folks are reading scaladoc to find out what methods they can call on a type and what parameters they can pass. We're kinda overloading users with way too much detail right how IMHO.

Here's another example...

def orElse[A1 <: A, B1 >: B](that: PartialFunction[A1, B1]): PartialFunction[A1, B1]

Now if we hid the generics declaration its easier to read

def orElse(that: PartialFunction[A1, B1]): PartialFunction[A1, B1]

Then if folks hover over, say, A1 we could show the declaration of A1 being A1 <: A. Covariant and contravariant types in generics add lots of noise too which can be rendered in a much easier to grok way to users I think.

We will usually need to do the inverse, if your json money field is an float, it may come as 3.1 , 3.15 or just 3.

In this case you may need to round it for proper display (and to be able to use a mask on an input field later):

floatvalue = 200.0; // it may be 200, 200.3 or 200.37, BigDecimal will take care
Locale locale = new Locale("en", "US");      
NumberFormat currencyFormatter = NumberFormat.getCurrencyInstance(locale);

BigDecimal valueAsBD = BigDecimal.valueOf(value);
    valueAsBD.setScale(2, BigDecimal.ROUND_HALF_UP); // add digits to match .00 pattern

System.out.println(currencyFormatter.format(amount));

Using Java 8, you can declare and initialize a two-dimensional array without using a (explicit) loop as follows:

int x = 20; // first dimension
int y = 4; // second dimension

double[][] a = IntStream.range(0, x)
                        .mapToObj(i -> new double[y])
                        .toArray(i -> new double[x][]);

This will initialize the arrays with default values (0.0 in the case of double).

In case you want to explicitly define the fill value to be used, You can add in a DoubleStream:

int x = 20; // first dimension
int y = 4; // second dimension
double v = 5.0; // fill value

double[][] a = IntStream
        .range(0, x)
        .mapToObj(i -> DoubleStream.generate(() -> v).limit(y).toArray())
        .toArray(i -> new double[x][]);

Depending on your use case, all the above solutions apply. This is how i usually do it however :

For server side code (e.g. a batch process) I usually load the entities and work with dynamic proxies. Usually in batch processes you need to load the data anyways at the time the service runs. I try to batch load the data instead of using the find method to save some time. Depending on the process I use optimistic or pessimistic concurrency control (I always use optimistic except for parallel execution scenarios where I need to lock some records with plain sql statements, this is rare though). Depending on the code and scenario the impact can be reduced to almost zero.

For client side scenarios, you have a few options

1. Use view models. The models should have a property UpdateStatus(unmodified-inserted-updated-deleted). It is the responsibility of the client to set the correct value to this column depending on the user actions (insert-update-delete). The server can either query the db for the original values or the client should send the original values to the server along with the changed rows. The server should attach the original values and use the UpdateStatus column for each row to decide how to handle the new values. In this scenario I always use optimistic concurrency. This will only do the insert - update - delete statements and not any selects, but it might need some clever code to walk the graph and update the entities (depends on your scenario - application). A mapper can help but does not handle the CRUD logic

2. Use a library like breeze.js that hides most of this complexity (as described in 1) and try to fit it to your use case.

Hope it helps

The answer is right in the MYSQL manual itself.

"DELETE FROM `table_name` WHERE `time_col` < ADDDATE(NOW(), INTERVAL -1 HOUR)"

Holy molly, I had to do all this in order for it to work. A picture is worth a thousand words.

• If you get this error while archiving then continue reading.

  

• Go to your app and click on the general tab. Under the signing section, uncheck "Automatically manage signing". As soon as you do that you will get a status of red error as shown below.

  

• Now here's the tricky part. You need to uncheck "Automatically manage Signing" in both the targets under your project. This step is very important.

  

• Now go under "build settings" tab of each of those targets and set "iOS Developer" under code signing identity. Do the same steps for your "PROJECT".

  

• Now do Xcode ? Product ? Clean. Close your project in Xcode and reopen it again.

• After this go to the general tab of each of your targets and check "Automatically manage signing" and under team drop down select your developer account

  

• Do an archive of your project again and everything should work.

Really, Apple? Was this supposed to make our lives easier?

Defining a new directive to work around a bug is not really ideal.

Because the datepicker displays later dates correctly, one simple workaround could be just setting the model variable to null first, and then to the current date after a while:

$scope.dt = null;
$timeout( function(){
    $scope.dt = new Date();
},100);

List comprehension is another way to create another column conditionally. If you are working with object dtypes in columns, like in your example, list comprehensions typically outperform most other methods.

Example list comprehension:

df['color'] = ['red' if x == 'Z' else 'green' for x in df['Set']]

%timeit tests:

import pandas as pd
import numpy as np

df = pd.DataFrame({'Type':list('ABBC'), 'Set':list('ZZXY')})
%timeit df['color'] = ['red' if x == 'Z' else 'green' for x in df['Set']]
%timeit df['color'] = np.where(df['Set']=='Z', 'green', 'red')
%timeit df['color'] = df.Set.map( lambda x: 'red' if x == 'Z' else 'green')

1000 loops, best of 3: 239 µs per loop

You can use group by for display distinct values and also corresponding fields.

select * from tabel_name group by FirstName

Now you got output like this:

ID    FirstName     LastName
2     Bugs          Bunny
1     John          Doe

If you want to answer like

ID    FirstName     LastName
1     John          Doe
2     Bugs          Bunny

then use this query,

select * from table_name group by FirstName order by ID

You can try this:

   var Enum = Object.freeze({
            Role: Object.freeze({ Administrator: 1, Manager: 2, Supervisor: 3 }),
            Color:Object.freeze({RED : 0, GREEN : 1, BLUE : 2 })
            });

    alert(Enum.Role.Supervisor);
    alert(Enum.Color.GREEN);
    var currentColor=0;
    if(currentColor == Enum.Color.RED) {
       alert('Its Red');
    }

You could use a string stream and read the elements into the vector.

Here are many different examples...

A copy of one of the examples:

std::vector<std::string> split(const std::string& s, char seperator)
{
   std::vector<std::string> output;

    std::string::size_type prev_pos = 0, pos = 0;

    while((pos = s.find(seperator, pos)) != std::string::npos)
    {
        std::string substring( s.substr(prev_pos, pos-prev_pos) );

        output.push_back(substring);

        prev_pos = ++pos;
    }

    output.push_back(s.substr(prev_pos, pos-prev_pos)); // Last word

    return output;
}

If unsure of compiled default for session.save_path, look at the pertinent php.ini.
Normally, this will show the commented out default value.

Ubuntu/Debian old/new php.ini locations:
Older php5 with Apache: /etc/php5/apache2/php.ini
Older php5 with NGINX+FPM: /etc/php5/fpm/php.ini
Ubuntu 16+ with Apache: /etc/php/*/apache2/php.ini *
Ubuntu 16+ with NGINX+FPM - /etc/php/*/fpm/php.ini *

* /*/ = the current PHP version(s) installed on system.

To show the PHP version in use under Apache:

$ a2query -m | grep "php" | grep -Eo "[0-9]+\.[0-9]+"

7.3

Since PHP 7.3 is the version running for this example, you would use that for the php.ini:

$ grep "session.save_path" /etc/php/7.3/apache2/php.ini

;session.save_path = "/var/lib/php/sessions"

Or, combined one-liner:

$ APACHEPHPVER=$(a2query -m | grep "php" | grep -Eo "[0-9]+\.[0-9]+") \ && grep ";session.save_path" /etc/php/${APACHEPHPVER}/apache2/php.ini

Result:

;session.save_path = "/var/lib/php/sessions"

Or, use PHP itself to grab the value using the "cli" environment (see NOTE below):

$ php -r 'echo session_save_path() . "\n";'
/var/lib/php/sessions
$

These will also work:

php -i | grep session.save_path

php -r 'echo phpinfo();' | grep session.save_path

NOTE:

The 'cli' (command line) version of php.ini normally has the same default values as the Apache2/FPM versions (at least as far as the session.save_path). You could also use a similar command to echo the web server's current PHP module settings to a webpage and use wget/curl to grab the info. There are many posts regarding phpinfo() use in this regard. But, it is quicker to just use the PHP interface or grep for it in the correct php.ini to show it's default value.

EDIT: Per @aesede comment -> Added php -i. Thanks

This works without needing jQuery:

var textArea = document.getElementById("my-text-area");
var arrayOfLines = textArea.value.split("\n"); // arrayOfLines is array where every element is string of one line

I found out a solution about excluding SecurityAutoConfiguration class.

Example:

@SpringBootApplication(exclude = {SecurityAutoConfiguration.class })
public class ReportApplication {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(MyApplication.class, args);
    }
}

Another alternative is to use a lambda:

ent.bind("<Return>", (lambda event: name_of_function()))

Full code:

from tkinter import *
from tkinter.messagebox import showinfo

def reply(name):
    showinfo(title="Reply", message = "Hello %s!" % name)


top = Tk()
top.title("Echo")
top.iconbitmap("Iconshock-Folder-Gallery.ico")

Label(top, text="Enter your name:").pack(side=TOP)
ent = Entry(top)
ent.bind("<Return>", (lambda event: reply(ent.get())))
ent.pack(side=TOP)
btn = Button(top,text="Submit", command=(lambda: reply(ent.get())))
btn.pack(side=LEFT)

top.mainloop()

As you can see, creating a lambda function with an unused variable "event" solves the problem.

You can use cat -

printf '%s' "some text at the beginning" | cat - filename

If you application depends on 3d-party code (in Xsl-scripts) then you have to decide first do you want to defend from bugs in them or not. If you really want to defend then I think you should execute your logic which prone to external errors in separate AppDomains. Catching StackOverflowException is not good.

Check also this question.

You can get this error with you have commented out HTML in a Flask application. Here the value for qual.date_expiry is None:

If you want to know the number of visitors (as is titled in the question) and not the number of pageviews, then you'll need to create a custom report.

Terminology

Google Analytics has changed the terminology they use within the reports. Now, visits is named "sessions" and unique visitors is named "users."

User - A unique person who has visited your website. Users may visit your website multiple times, and they will only be counted once.

Session - The number of different times that a visitor came to your site.

Pageviews - The total number of pages that a user has accessed.

Creating a Custom Report

1. To create a custom report, click on the "Customization" item in the left navigation menu, and then click on "Custom Reports".

2. The "Create Custom Report" page will open.
3. Enter a name for your report.
4. In the "Metric Groups" section, enter either "Users" or "Sessions" depending on what information you want to collect (see Terminology, above).
5. In the "Dimension Drilldowns" section, enter "Page".
6. Under "Filters" enter the individual page (exact) or group of pages (using regex) that you would like to see the data for.
7. Save the report and run it.

The idea of a foreign key is based on the concept of referencing a value that already exists in the main table. That is why it is called a foreign key in the other table. This concept is called referential integrity. If a foreign key is declared as a null field it will violate the the very logic of referential integrity. What will it refer to? It can only refer to something that is present in the main table. Hence, I think it would be wrong to declare a foreign key field as null.

That specifies the how many digits you want it to show.

integer value or * that specifies minimum field width. The result is padded with space characters (by default), if required, on the left when right-justified, or on the right if left-justified. In the case when * is used, the width is specified by an additional argument of type int. If the value of the argument is negative, it results with the - flag specified and positive field width.

You can use the .indexOf() and .substring(), like this:

var url = "www.aaa.com/task1/1.3.html#a_1";
var hash = url.substring(url.indexOf("#")+1);

You can give it a try here, if it may not have a # in it, do an if(url.indexOf("#") != -1) check like this:

var url = "www.aaa.com/task1/1.3.html#a_1", idx = url.indexOf("#");
var hash = idx != -1 ? url.substring(idx+1) : "";

If this is the current page URL, you can just use window.location.hash to get it, and replace the # if you wish.

Based on @carlosfigueira 's answer, I looked further into WebClient's methods and found UploadValues, which is exactly what I want:

Using client As New Net.WebClient
    Dim reqparm As New Specialized.NameValueCollection
    reqparm.Add("param1", "somevalue")
    reqparm.Add("param2", "othervalue")
    Dim responsebytes = client.UploadValues(someurl, "POST", reqparm)
    Dim responsebody = (New Text.UTF8Encoding).GetString(responsebytes)
End Using

The key part is this:

client.UploadValues(someurl, "POST", reqparm)

It sends whatever verb I type in, and it also helps me create a properly url encoded form data, I just have to supply the parameters as a namevaluecollection.

$data_arr = array('hello', 'developer', 'laravel' );


// We Have to remove Value "hello" from the array
// Check if the value is exists in the array

if (array_search('hello', $data_arr ) !== false) {
     
     $key = array_search('hello', $data_arr );
     
     unset( $data_arr[$key] );
}



# output:
// It will Return unsorted Indexed array
print( $data_arr )


// To Sort Array index use this
$data_arr = array_values( $data_arr );


// Now the array key is sorted

This is a great article for syntax needed to create new objects from a LINQ query.

But, if the assignments to fill in the fields of the object are anything more than simple assignments, for example, parsing strings to integers, and one of them fails, it is not possible to debug this. You can not create a breakpoint on any of the individual assignments.

And if you move all the assignments to a subroutine, and return a new object from there, and attempt to set a breakpoint in that routine, you can set a breakpoint in that routine, but the breakpoint will never be triggered.

So instead of:

var query2 = from c in doc.Descendants("SuggestionItem")
                select new SuggestionItem
                       { Phrase = c.Element("Phrase").Value
                         Blocked = bool.Parse(c.Element("Blocked").Value),
                         SeenCount = int.Parse(c.Element("SeenCount").Value)
                       };

Or

var query2 = from c in doc.Descendants("SuggestionItem")
                         select new SuggestionItem(c);

I instead did this:

List<SuggestionItem> retList = new List<SuggestionItem>();

var query = from c in doc.Descendants("SuggestionItem") select c;

foreach (XElement item in query)
{
    SuggestionItem anItem = new SuggestionItem(item);
    retList.Add(anItem);
}

This allowed me to easily debug and figure out which assignment was failing. In this case, the XElement was missing a field I was parsing for to set in the SuggestionItem.

I ran into these gotchas with Visual Studio 2017 while writing unit tests for a new library routine.

In plain English, the syntax explained:

if(condition){
    do_something_if_condition_is_met;
}
else{
    do_something_else_if_condition_is_not_met;
}

Can be written as:

condition ? do_something_if_condition_is_met : do_something_else_if_condition_is_not_met;

            Double distance = lld1.distance(lld2);
            Log.d(TAG, "Distance in kilometers " + distance);

This works for me:

git rm -r --cached --ignore-unmatch folder_name

--ignore-unmatch is important here, without that option git will exit with error on the first file not in the index.

If you add the following you can set the background colour or image (your css)

 html { 
     background-image: url('http://yoursite/i/tile.jpg');
     background-repeat: repeat; 
 }

 .body {
     background-color: transparent; 
 }

This is because BS applies a css rule for background colour and also for the .container class.

From the Flask API Documentation (v. 0.10):

flask.redirect(location, code=302, Response=None)

Returns a response object (a WSGI application) that, if called, redirects the client to the target location. Supported codes are 301, 302, 303, 305, and 307. 300 is not supported because it’s not a real redirect and 304 because it’s the answer for a request with a request with defined If-Modified-Since headers.

New in version 0.6: The location can now be a unicode string that is encoded using the iri_to_uri() function.

Parameters:

• location – the location the response should redirect to.
• code – the redirect status code. defaults to 302.
• Response (class) – a Response class to use when instantiating a response. The default is werkzeug.wrappers.Response if unspecified.

The easiest way to do this, with excellent performance and compatibility with both old and new browsers, is to include either Lo-Dash or Underscore in your page.

Then you can use either _.size(object) or _.keys(object).length

For your obj.Data, you could test this with:

console.log( _.size(obj.Data) );

or:

console.log( _.keys(obj.Data).length );

Lo-Dash and Underscore are both excellent libraries; you would find either one very useful in your code. (They are rather similar to each other; Lo-Dash is a newer version with some advantanges.)

Alternatively, you could include this function in your code, which simply loops through the object's properties and counts them:

function ObjectLength( object ) {
    var length = 0;
    for( var key in object ) {
        if( object.hasOwnProperty(key) ) {
            ++length;
        }
    }
    return length;
};

You can test this with:

console.log( ObjectLength(obj.Data) );

That code is not as fast as it could be in modern browsers, though. For a version that's much faster in modern browsers and still works in old ones, you can use:

function ObjectLength_Modern( object ) {
    return Object.keys(object).length;
}

function ObjectLength_Legacy( object ) {
    var length = 0;
    for( var key in object ) {
        if( object.hasOwnProperty(key) ) {
            ++length;
        }
    }
    return length;
}

var ObjectLength =
    Object.keys ? ObjectLength_Modern : ObjectLength_Legacy;

and as before, test it with:

console.log( ObjectLength(obj.Data) );

This code uses Object.keys(object).length in modern browsers and falls back to counting in a loop for old browsers.

But if you're going to all this work, I would recommend using Lo-Dash or Underscore instead and get all the benefits those libraries offer.

I set up a jsPerf that compares the speed of these various approaches. Please run it in any browsers you have handy to add to the tests.

Thanks to Barmar for suggesting Object.keys for newer browsers in his answer.

In my experience, the "I" convention applies to interfaces that are intended to provide a contract to a class, particularly when the interface itself is not an abstract notion of the class.

For example, in your case, I'd only expect to see IUser if the only user you ever intend to have is User. If you plan to have different types of users - NoviceUser, ExpertUser, etc. - I would expect to see a User interface (and, perhaps, an AbstractUser class that implements some common functionality, like get/setName()).

I would also expect interfaces that define capabilities - Comparable, Iterable, etc. - to be named like that, and not like IComparable or IIterable.

The simple way to solve this problem in Spring 3.1.1 is that: add following configuration codes in servlet-context.xml

    <annotation-driven>
    <message-converters register-defaults="true">
    <beans:bean class="org.springframework.http.converter.StringHttpMessageConverter">
    <beans:property name="supportedMediaTypes">    
    <beans:value>text/plain;charset=UTF-8</beans:value>
    </beans:property>
    </beans:bean>
    </message-converters>
    </annotation-driven>

Don't need to override or implement anything.

Instead of a RegEx use Replace for something that simple:

LastName = LastName.Replace(" ", String.Empty);

On Mountain Lion I was facing same issue, which was resolved by adding /usr/include/libxml2 to include paths with flag "recursive", use this if all above is not fruitful.

To resolve this,

Go to your XAMPP folder,

XAMPP -> mysql -> bin -> "my.ini"

After opening my.ini configuration file, Replace 3306 with 3308 in couple of places, because 3308 is a free port.

XAMPP -> php -> "php.ini"

Do the same as you did in "my.ini" file which is changing port 3306 to 3308.

Then, restart the XAMPP server.

It works fine.

You can use the Math.Max method to return the maximum of two numbers, e.g. for int:

int maximum = Math.Max(number1, Math.Max(number2, number3))

There ist also the Max() method from LINQ which you can use on any IEnumerable.

You could use a wrapper around the original array (which is IList), like in this (untested) piece of code.

public class SubList<T> : IList<T>

    #region Fields

    private readonly int startIndex;
    private readonly int endIndex;

        this.startIndex = startIndex;
        this.count = count;
        this.endIndex = this.startIndex + this.count - 1;
    }

    #region IList<T> Members

    public int IndexOf(T item)
    {
        if (item != null)
        {
            for (int i = this.startIndex; i <= this.endIndex; i++)

                if (item.Equals(this.source[i]))
                    return i;
            }
        }
        else
        {
            for (int i = this.startIndex; i <= this.endIndex; i++)
            {
                if (this.source[i] == null)
                    return i;
            }
        }
        return -1;
    }

    public void Insert(int index, T item)
    {
        throw new NotSupportedException();
    }

    public void RemoveAt(int index)
    {

    }

    public T this[int index]
    {

        {
            if (index >= 0 && index < this.count)
                return this.source[index + this.startIndex];
            else
                throw new IndexOutOfRangeException("index");
        }
        set
        {
            if (index >= 0 && index < this.count)
                this.source[index + this.startIndex] = value;
            else

        }
    }

    public void Add(T item)

    public void Clear()

        throw new NotSupportedException();
    }

    public bool Contains(T item)
    {
        return this.IndexOf(item) >= 0;
    }

    public void CopyTo(T[] array, int arrayIndex)

While the results vary in this case because the column names are numbers, another way I've used is data.frame(rbind(mytable)). Using the example from @X.X:

> freq_t = table(cyl = mtcars$cyl, gear = mtcars$gear)

> freq_t
   gear
cyl  3  4  5
  4  1  8  2
  6  2  4  1
  8 12  0  2

> data.frame(rbind(freq_t))
  X3 X4 X5
4  1  8  2
6  2  4  1
8 12  0  2

If the column names do not start with numbers, the X won't get added to the front of them.

You should use model

comboBox.getModel().setSelectedItem(object);

This is slighly more OS independent way:

# do this init somewhere
import pygame
pygame.init()
screen = pygame.display.set_mode((640, 480))
font = pygame.font.Font(pygame.font.get_default_font(), 36)

# now print the text
text_surface = font.render('Hello world', antialias=True, color=(0, 0, 0))
screen.blit(text_surface, dest=(0,0))

You may also have to change the "less secure apps" setting on your Gmail account. EnableSsl, use port 587 and enable "less secure apps". If you google the less secure apps part there are google help pages that will link you right to the page for your account. That was my problem but everything is working now thanks to all the answers above.

From the standard (p. ii):

It is expected that other standards will refer to this one, strictly adhering to the JSON text format, while imposing restrictions on various encoding details. Such standards may require specific behaviours. JSON itself specifies no behaviour.

Further down in the standard (p. 2), the specification for a JSON object:

An object structure is represented as a pair of curly bracket tokens surrounding zero or more name/value pairs. A name is a string. A single colon token follows each name, separating the name from the value. A single comma token separates a value from a following name.

It does not make any mention of duplicate keys being invalid or valid, so according to the specification I would safely assume that means they are allowed.

That most implementations of JSON libraries do not accept duplicate keys does not conflict with the standard, because of the first quote.

Here are two examples related to the C++ standard library. When deserializing some JSON object into a std::map it would make sense to refuse duplicate keys. But when deserializing some JSON object into a std::multimap it would make sense to accept duplicate keys as normal.

Another option:

content = dict(k1='foo', k2='nope', k3='bar')
selection = ['k1', 'k3']
filtered = filter(lambda i: i[0] in selection, content.items())

But you get a list (Python 2) or an iterator (Python 3) returned by filter(), not a dict.

i can bring a little help here... it seems that when you use say background-image: url("/images/image.jpg"); or background-image: url("images/image.jpg"); or background-image: url("../images/image.jpg"); different browsers appear to see this differently. the first the browser seems to see this as domain.com/images/image.jpg.... the second the browser sees at domain.com/css/images/image.jpg.... and the final the browser sees as domain.com/PathToImageFile/image.jpg... hopes this helps

1) I tried Broadcast Receiver approach as well even though I know CONNECTIVITY_ACTION/CONNECTIVITY_CHANGE is deprecated in API 28 and not recommended. Also bound to using explicit register, it listens as long as app is running.

2) I also tried Firebase Dispatcher which works but not beyond app killed.

3) Recommended way found is WorkManager to guarantee execution beyond process killed and internally using registerNetworkRequest()

The biggest evidence in favor of #3 approach is referred by Android doc itself. Especially for apps in the background.

Also here

In Android 7.0 we're removing three commonly-used implicit broadcasts — CONNECTIVITY_ACTION, ACTION_NEW_PICTURE, and ACTION_NEW_VIDEO — since those can wake the background processes of multiple apps at once and strain memory and battery. If your app is receiving these, take advantage of the Android 7.0 to migrate to JobScheduler and related APIs instead.

So far it works fine for us using Periodic WorkManager request.

Update: I ended up writing 2 series medium post about it.

I know this post is kinda old but...

  As 'witttness' pointed out.

About Your Own Custom Theme You might choose to modify bootstrap-theme.css when creating your own theme. Doing so may make it easier to make styling changes without accidentally breaking any of that built-in Bootstrap goodness.

  I see it as Bootstrap has seen over the years that everyone wants something a bit different than the core styles. While you could modify bootstrap.css it might break things and it could make updating to a newer version a real pain and time consuming. Downloading from a 'theme' site means you have to wait on if that creator updates that theme, big if sometimes, right?

  Some build their own 'custom.css' file and that's ok, but if you use 'bootstrap-theme.css' a lot of stuff is already built and this allows you to roll your own theme faster 'without' disrupting the core of bootstrap.css. I for one don't like the 3D buttons and gradients most of the time, so change them using bootstrap-theme.css. Add margins or padding, change the radius to your buttons, and so on...

I have solved it this way.

Go to your project file let's say project/name/bin and delete everything within the bin folder. (this will then give you another error which you can solve this way)

then in your visual studio right click project's References folder, to open NuGet Package Manager.

Go to browse and install "DotNetCompilerPlatform".

As of Node.js v6.0.0 using the constructor method has been deprecated and the following method should instead be used to construct a new buffer from a base64 encoded string:

var b64string = /* whatever */;
var buf = Buffer.from(b64string, 'base64'); // Ta-da

For Node.js v5.11.1 and below

Construct a new Buffer and pass 'base64' as the second argument:

var b64string = /* whatever */;
var buf = new Buffer(b64string, 'base64'); // Ta-da

If you want to be clean, you can check whether from exists :

if (typeof Buffer.from === "function") {
    // Node 5.10+
    buf = Buffer.from(b64string, 'base64'); // Ta-da
} else {
    // older Node versions, now deprecated
    buf = new Buffer(b64string, 'base64'); // Ta-da
}

In some circumstances it might be useful to simply remove the bindings and then re-apply:

ko.cleanNode(document.getElementById(element_id))
ko.applyBindings(viewModel, document.getElementById(element_id))

I don't think you can set that option there. You will have to use jQuery.ajax() with the appropriate parameters (basically getJSON just wraps that call into an easier API, as well).

You could default the parameter to null or false.
This way, it would be shorter to test if a value has been passed as parameter.

@mixin clearfix($width: null) {

  @if not ($width) {

    // if width is not passed, or empty do this

  } @else {

    display: inline-block;
    width: $width;

  }
}

use them in Java code like this:

 color = getResources().getColor(R.color.mycolor);

The getResources() method returns the ResourceManager class for the current activity, and getColor() asks the manager to look up a color given a resource ID

The important thing about a sprint is that: within a sprint the functionality that is to be delivered is fixed.

A sprint is normally an iteration. But you can for example have a 4 week sprint, but have 4 one week "internal" iterations within that sprint.

There is a lot of discussion about the length of sprints. I think that if you do it according to the book they should all be the same length.

We have found that a short first sprint to get the development environment up and running, followed by longer basic functionality sprints, then short sprints towards the end of the project, has worked for us.

You can use all

> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE

On a similar note, if you want to check whether any of the elements is TRUE you can use any

> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE

If you use Unix system, you can solve your problem in two commands. Where the first initialize configs and the second alters file with a file to ignore.

$ git config --global core.excludesfile ~/.gitignore
$ echo '.idea' >> ~/.gitignore

Add your <script> to the bottom of your <body>, or add an event listener for DOMContentLoaded following this StackOverflow question.

If that script executes in the <head> section of the code, document.getElementsByClassName(...) will return an empty array because the DOM is not loaded yet.

You're getting the Type Error because you're referencing search_span[0], but search_span[0] is undefined.

This works when you execute it in Dev Tools because the DOM is already loaded.

See Introducing XML Serialization:

Items That Can Be Serialized

The following items can be serialized using the XmlSerializer class:

• Public read/write properties and fields of public classes
• Classes that implement ICollection or IEnumerable
• XmlElement objects
• XmlNode objects
• DataSet objects

In particular, ISerializable or the [Serializable] attribute does not matter.

Now that you've told us what your problem is ("it doesn't work" is not a problem statement), you can get answers to your actual problem, instead of guesses.

When you serialize a collection of a type, but will actually be serializing a collection of instances of derived types, you need to let the serializer know which types you will actually be serializing. This is also true for collections of object.

You need to use the XmlSerializer(Type,Type[]) constructor to give the list of possible types.

Sure it's clever to use find and then xargs, but you're doing it the hard way.
