First, you're missing some parentheses in your conditional:

if ($("#about").hasClass("opened")) {
  $("#about").animate({right: "-700px"}, 2000);
}

But you can also simplify this to:

$('#about.opened').animate(...);

If #about doesn't have the opened class, it won't animate.

If the problem is with the animation itself, we'd need to know more about your element positioning (absolute? absolute inside relative parent? does the parent have layout?)

Rails 4:

def change
  change_column_null(:users, :admin, false )
end

As others have noted, most likely you don't have .html set up to handle php code.

Having said that, if all you're doing is using index.html to include index.php, your question should probably be 'how do I use index.php as index document?

In which case, for Apache (httpd.conf), search for DirectoryIndex and replace the line with this (will only work if you have dir_module enabled, but that's default on most installs):

DirectoryIndex index.php

If you use other directory indexes, list them in order of preference i.e.

DirectoryIndex index.php index.phtml index.html index.htm

I found a way to print the background image with CSS. It's a bit dependent on how your background is laid out, but it seems to work for my application.

Essentially, you add the @media print to the end of your stylesheet and change the body background slightly.

Example, if your current CSS looks like this:

body {
background:url(images/mybg.png) no-repeat;
}

At the end of your stylesheet, you add:

@media print {
body {
   content:url(images/mybg.png);
  }
}

This adds the image to the body as a "foreground" image, thus making it printable. You may need to add some additional CSS to make the z-index proper. But again, its up to how your page is laid out.

This worked for me when I couldn't get a header image to show up in print view.

If you only care about that particular machine's traffic, use a capture filter instead, which you can set under Capture -> Options.

host 192.168.1.101

Wireshark will only capture packet sent to or received by 192.168.1.101. This has the benefit of requiring less processing, which lowers the chances of important packets being dropped (missed).

Another option like Gavin Palmer answer is to use the .pem file but with a curl option

1. download the last updated .pem file from https://curl.haxx.se/docs/caextract.html and save it somewhere on your server(outside the public folder)

2. set the option in your code instead of the php.ini file.

In your code

curl_setopt($ch, CURLOPT_CAINFO, $_SERVER['DOCUMENT_ROOT'] .  "/../cacert-2017-09-20.pem");

NOTE: setting the cainfo in the php.ini like @Gavin Palmer did is better than setting it in your code like I did, because it will save a disk IO every time the function is called, I just make it like this in case you want to test the cainfo file on the fly instead of changing the php.ini while testing your function.

If you are on Python3 you can also use the library PILasOPENCV which works in Python 2 and 3. Function api calls are the same as in PIL or pillow but internally it works with OpenCV and numpy to load, save and manipulate images. Have a look at https://github.com/bunkahle/PILasOPENCV or install it with pip install PILasOPENCV. Not all PIL functions have been simulated but the most common functions work.

Please see the following Python shell scripting execution in sequence, it will give the solution from creation of class to extracting the field names of instances.

Look at the package DBMS_Redefinition. It will rebuild the table with the new ordering. It can be done with the table online.

As Phil Brown noted, think carefully before doing this. However there is overhead in scanning the row for columns and moving data on update. Column ordering rules I use (in no particular order):

• Group related columns together.
• Not NULL columns before null-able columns.
• Frequently searched un-indexed columns first.
• Rarely filled null-able columns last.
• Static columns first.
• Updateable varchar columns later.
• Indexed columns after other searchable columns.

These rules conflict and have not all been tested for performance on the latest release. Most have been tested in practice, but I didn't document the results. Placement options target one of three conflicting goals: easy to understand column placement; fast data retrieval; and minimal data movement on updates.

Another way using dictionary comprehensions,

>>> t = [('A', 1), ('B', 2), ('C', 3)]
>>> d = { i:j for i,j in t }
>>> d
{'A': 1, 'B': 2, 'C': 3}

If you are facing any issues during push ( in windows OS), just remove the cached git account by following the given steps below: 1. Search for Control panel and open the same. 2. Search for Credential Manager and open this. 3. Click on Windows Credentials under Manage your credentials page. 4. Under Generic Credentials click on GitHub. 5. Click on Remove and then confirm by clicking Yes button. 6. Now start pushing the code and you will get GitHub popup to login again and now you are done. Everything will work properly after successful login.

When you want to align it to the right, add \hfill.

I use:

\renewcommand{\qed}{\hfill\blacksquare}

I would like to provide another variant that should be both performant and powerful, because

• it does not use the sometimes slower Match)
• supports String, Integer, Boolean etc. (not String-only)
• returns the index of the searched-for item
• supports nth-occurrence

...

'-1 if not found
'https://stackoverflow.com/a/56327647/1915920
Public Function IsInArray( _
  item As Variant, _
  arr As Variant, _
  Optional nthOccurrence As Long = 1 _
  ) As Long

    IsInArray = -1

    Dim i As Long:  For i = LBound(arr, 1) To UBound(arr, 1)
        If arr(i) = item Then
            If nthOccurrence > 1 Then
                nthOccurrence = nthOccurrence - 1
                GoTo continue
            End If
            IsInArray = i
            Exit Function
        End If
continue:
    Next i

End Function

use it like this:

Sub testInt()
  Debug.Print IsInArray(2, Array(1, 2, 3))  '=> 1
End Sub

Sub testString1()
  Debug.Print IsInArray("b", Array("a", "b", "c", "a"))  '=> 1
End Sub

Sub testString2()
  Debug.Print IsInArray("b", Array("a", "b", "c", "b"), 2)  '=> 3
End Sub

Sub testBool1()
  Debug.Print IsInArray(False, Array(True, False, True))  '=> 1
End Sub

Sub testBool2()
  Debug.Print IsInArray(True, Array(True, False, True), 2)  '=> 2
End Sub

My answer works like the others here, but I'll post it because it looks a bit faster than the other Python solutions, from setting up the dictionary faster. (I checked this against John Fouhy's solution.) After setup, the time to solve is down in the noise.

grid = "fxie amlo ewbx astu".split()
nrows, ncols = len(grid), len(grid[0])

# A dictionary word that could be a solution must use only the grid's
# letters and have length >= 3. (With a case-insensitive match.)
import re
alphabet = ''.join(set(''.join(grid)))
bogglable = re.compile('[' + alphabet + ']{3,}$', re.I).match

words = set(word.rstrip('\n') for word in open('words') if bogglable(word))
prefixes = set(word[:i] for word in words
               for i in range(2, len(word)+1))

def solve():
    for y, row in enumerate(grid):
        for x, letter in enumerate(row):
            for result in extending(letter, ((x, y),)):
                yield result

def extending(prefix, path):
    if prefix in words:
        yield (prefix, path)
    for (nx, ny) in neighbors(path[-1]):
        if (nx, ny) not in path:
            prefix1 = prefix + grid[ny][nx]
            if prefix1 in prefixes:
                for result in extending(prefix1, path + ((nx, ny),)):
                    yield result

def neighbors((x, y)):
    for nx in range(max(0, x-1), min(x+2, ncols)):
        for ny in range(max(0, y-1), min(y+2, nrows)):
            yield (nx, ny)

Sample usage:

# Print a maximal-length word and its path:
print max(solve(), key=lambda (word, path): len(word))

Edit: Filter out words less than 3 letters long.

Edit 2: I was curious why Kent Fredric's Perl solution was faster; it turns out to use regular-expression matching instead of a set of characters. Doing the same in Python about doubles the speed.

You may use TypeToken to load the json string into a custom object.

logs = gson.fromJson(br, new TypeToken<List<JsonLog>>(){}.getType());

Documentation:

Represents a generic type T.

Java doesn't yet provide a way to represent generic types, so this class does. Forces clients to create a subclass of this class which enables retrieval the type information even at runtime.

For example, to create a type literal for List<String>, you can create an empty anonymous inner class:

TypeToken<List<String>> list = new TypeToken<List<String>>() {};

This syntax cannot be used to create type literals that have wildcard parameters, such as Class<?> or List<? extends CharSequence>.

Kotlin:

If you need to do it in Kotlin you can do it like this:

val myType = object : TypeToken<List<JsonLong>>() {}.type
val logs = gson.fromJson<List<JsonLong>>(br, myType)

Or you can see this answer for various alternatives.

I think that is easier than this.

• First, create a blank target database.
• Then, in "SQL Server Management Studio" restore wizard, look for the option to overwrite target database. It is in the 'Options' tab and is called 'Overwrite the existing database (WITH REPLACE)'. Check it.
• Remember to select target files in 'Files' page.

You can change 'tabs' at left side of the wizard (General, Files, Options)

From the manual:

If the database server successfully prepares the statement, PDO::prepare() returns a PDOStatement object. If the database server cannot successfully prepare the statement, PDO::prepare() returns FALSE or emits PDOException (depending on error handling).

The prepare statement likely caused an error because the db would be unable to prepare the statement. Try testing for an error immediately after you prepare your query and before you execute it.

$qry = '
    INSERT INTO non-existant-table (id, score) 
    SELECT id, 40 
    FROM another-non-existant-table
    WHERE description LIKE "%:search_string%"
    AND available = "yes"
    ON DUPLICATE KEY UPDATE score = score + 40
';
$sth = $this->pdo->prepare($qry);
print_r($this->pdo->errorInfo());

Store it in multi valued column with a comma separator in an RDBMs table.

I chose to rename all instances instead of destroy/replace - since sometimes the AJAX loaded instance doesn't really replace the one on the core of the page... keeps more in RAM, but less conflict this way.

    if (CKEDITOR && CKEDITOR.instances) {
        for (var oldName in CKEDITOR.instances) {
            var newName = "ajax"+oldName;
            CKEDITOR.instances[newName] = CKEDITOR.instances[oldName];
            CKEDITOR.instances[newName].name = newName;
            delete CKEDITOR.instances[oldName];
        }
    }

You would use the read.csv function; for example:

dat = read.csv("spam.csv", header = TRUE)

You can also reference this tutorial for more details.

Note: make sure the .csv file to read is in your working directory (using getwd()) or specify the right path to file. If you want, you can set the current directory using setwd.

Keep in mind that if you want to keep the white spaces within a string, you may remove them unintentionally using some approaches. If you have this list

['hello world', ' ', '', 'hello'] what you may want ['hello world','hello']

first trim the list to convert any type of white space to empty string:

space_to_empty = [x.strip() for x in _text_list]

then remove empty string from them list

space_clean_list = [x for x in space_to_empty if x]

EventLog.SourceExists enumerates through the subkeys of HKLM\SYSTEM\CurrentControlSet\services\eventlog to see if it contains a subkey with the specified name. If the user account under which the code is running does not have read access to a subkey that it attempts to access (in your case, the Security subkey) before finding the target source, you will see an exception like the one you have described.

The usual approach for handling such issues is to register event log sources at installation time (under an administrator account), then assume that they exist at runtime, allowing any resulting exception to be treated as unexpected if a target event log source does not actually exist at runtime.

class Test:
    @pytest.fixture()

    def test_that_depends_on_resource(self, setUp):
        print("testing {}".format(setUp))

In order to run:

[update 2015-09-28] Now Google lets you add custom domains (including naked domains) and setup SSL without the need of Google Apps. For details refer to here: https://cloud.google.com/appengine/docs/using-custom-domains-and-ssl?hl=en

I just discovered today (as of 2014-04-11) a new custom domain settings page is available from Google Developers Console:

1. Go to https://console.developers.google.com/project 2. Click on your project 3. On the left click "App Engine" 4. Click "Settings"

There you go! You can configure custom domain without the need of Google App account!

You can not directly send an email with a HTML form. You can however send the form to your web server and then generate the email with a server side program written in e.g. PHP.

The other solution is to create a link as you did with the "mailto:". This will open the local email program from the user. And he/she can then send the pre-populated email.

When you decided how you wanted to do it you can ask another (more specific) question on this site. (Or you can search for a solution somewhere on the internet.)

I found another solution. Create qt.conf in the app folder as such:

[Paths]
Prefix = .

And then copy the plugins folder into the app folder and it works for me.

I have created an Asset helper of my own.

First I defined the asset types and path in app/config/assets.php:

return array(

    /*
    |--------------------------------------------------------------------------
    | Assets paths
    |--------------------------------------------------------------------------
    |
    | Location of all application assets, relative to the public folder,
    | may be used together with absolute paths or with URLs.
    |
    */

    'images' => '/storage/images',
    'css' => '/assets/css',
    'img' => '/assets/img',
    'js' => '/assets/js'
);

Then the actual Asset class:

class Asset
{
    private static function getUrl($type, $file)
    {
        return URL::to(Config::get('assets.' . $type) . '/' . $file);
    }

    public static function css($file)
    {
        return self::getUrl('css', $file);
    }

    public static function img($file)
    {
        return self::getUrl('img', $file);
    }

    public static function js($file)
    {
        return self::getUrl('js', $file);
    }

}

So in my view I can do this to show an image:

{{ HTML::image(Asset::img('logo.png'), "My logo")) }}

Or like this to implement a Java script:

{{ HTML::script(Asset::js('my_script.js')) }}

@last_run_time is a 9.4. User-Defined Variables and last_run_time datetime one 13.6.4.1. Local Variable DECLARE Syntax, are different variables.

Try: SELECT last_run_time;

UPDATE

Example:

/* CODE FOR DEMONSTRATION PURPOSES */
DELIMITER $$

CREATE PROCEDURE `sp_test`()
BEGIN
    DECLARE current_procedure_name CHAR(60) DEFAULT 'accounts_general';
    DECLARE last_run_time DATETIME DEFAULT NULL;
    DECLARE current_run_time DATETIME DEFAULT NOW();

    -- Define the last run time
    SET last_run_time := (SELECT MAX(runtime) FROM dynamo.runtimes WHERE procedure_name = current_procedure_name);

    -- if there is no last run time found then use yesterday as starting point
    IF(last_run_time IS NULL) THEN
        SET last_run_time := DATE_SUB(NOW(), INTERVAL 1 DAY);
    END IF;

    SELECT last_run_time;

    -- Insert variables in table2
    INSERT INTO table2 (col0, col1, col2) VALUES (current_procedure_name, last_run_time, current_run_time);
END$$

DELIMITER ;

I had a similar need for splitting CSV values from SQL insert statements.

In my case, I could assume that strings were wrapped in single quotations and numbers were not.

csv.split(/,((?=')|(?=\d))/g).filter(function(x) { return x !== '';});

For some probably obvious reason, this regex produces some blank results. I could ignore those, since any empty values in my data were represented as ...,'',... and not ...,,....

You can use CSS to set the opacity, and than use javascript to apply the styles to a certain element in the DOM.

.opClass {
    opacity:0.4;
    filter:alpha(opacity=40); /* For IE8 and earlier */
}

Than use (for example) jQuery to change the style:

$('#element_id').addClass('opClass');

Or with plain javascript, like this:

document.getElementById("element_id").className = "opClass";

Try like this:

$data = array('current_login' => date('Y-m-d H:i:s'));
$this->db->set('last_login', 'current_login', false);
$this->db->where('id', 'some_id');
$this->db->update('login_table', $data);

Pay particular attention to the set() call's 3rd parameter. false prevents CodeIgniter from quoting the 2nd parameter -- this allows the value to be treated as a table column and not a string value. For any data that doesn't need to special treatment, you can lump all of those declarations into the $data array.

The query generated by above code:

UPDATE `login_table`
SET last_login = current_login, `current_login` = '2018-01-18 15:24:13'
WHERE `id` = 'some_id'

EDIT

I think the reason that your table is not responsive to start with was you did not wrap in .container, .row and .col-md-x classes like this one

<div class="container">
   <div class="row">
     <div class="col-md-12">
     <!-- or use any other number .col-md- -->
         <div class="table-responsive">
             <div class="table">
             </div>
         </div>
     </div>
   </div>
</div>

With this, you can still use <p> tags and even make it responsive.

Please see the Bootply example here

I would use it like this, its way shorter and it won't give any problems

        dynamic result = null;
        if (methodInfo != null)
        {
            ParameterInfo[] parameters = methodInfo.GetParameters();
            object classInstance = Activator.CreateInstance(type, null);
            result = methodInfo.Invoke(classInstance, parameters.Length == 0 ? null : parametersArray);
        }

A lambda is a type of function, defined inline. Along with a lambda you also usually have some kind of variable type that can hold a reference to a function, lambda or otherwise.

For instance, here's a C# piece of code that doesn't use a lambda:

public Int32 Add(Int32 a, Int32 b)
{
    return a + b;
}

public Int32 Sub(Int32 a, Int32 b)
{
    return a - b;
}

public delegate Int32 Op(Int32 a, Int32 b);

public void Calculator(Int32 a, Int32 b, Op op)
{
    Console.WriteLine("Calculator: op(" + a + ", " + b + ") = " + op(a, b));
}

public void Test()
{
    Calculator(10, 23, Add);
    Calculator(10, 23, Sub);
}

This calls Calculator, passing along not just two numbers, but which method to call inside Calculator to obtain the results of the calculation.

In C# 2.0 we got anonymous methods, which shortens the above code to:

public delegate Int32 Op(Int32 a, Int32 b);

public void Calculator(Int32 a, Int32 b, Op op)
{
    Console.WriteLine("Calculator: op(" + a + ", " + b + ") = " + op(a, b));
}

public void Test()
{
    Calculator(10, 23, delegate(Int32 a, Int32 b)
    {
        return a + b;
    });
    Calculator(10, 23, delegate(Int32 a, Int32 b)
    {
        return a - b;
    });
}

And then in C# 3.0 we got lambdas which makes the code even shorter:

public delegate Int32 Op(Int32 a, Int32 b);

public void Calculator(Int32 a, Int32 b, Op op)
{
    Console.WriteLine("Calculator: op(" + a + ", " + b + ") = " + op(a, b));
}

public void Test()
{
    Calculator(10, 23, (a, b) => a + b);
    Calculator(10, 23, (a, b) => a - b);
}

That's because you created a Web Site instead of a Web Application. The cs/vb files can only be seen in a Web Application, but in a website you can't have a separate cs/vb file.

Edit: In the website you can add a cs file behavior like..

<%@ Application CodeFile="Global.asax.cs" Inherits="ApplicationName.MyApplication" Language="C#" %>

~/Global.asax.cs:

namespace ApplicationName
{
    public partial class MyApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
        }
    }
}

There is a problem with the accepted answer. I think we need to use "valid" instead of "same" here - return numpy.convolve(interval, window, 'same') .

As an Example try out the MA of this data-set = [1,5,7,2,6,7,8,2,2,7,8,3,7,3,7,3,15,6] - the result should be [4.2,5.4,6.0,5.0,5.0,5.2,5.4,4.4,5.4,5.6,5.6,4.6,7.0,6.8], but having "same" gives us an incorrect output of [2.6,3.0,4.2,5.4,6.0,5.0,5.0,5.2,5.4,4.4,5.4,5.6,5.6, 4.6,7.0,6.8,6.2,4.8]

Rusty code to try this out -:

result=[]
dataset=[1,5,7,2,6,7,8,2,2,7,8,3,7,3,7,3,15,6]
window_size=5
for index in xrange(len(dataset)):
    if index <=len(dataset)-window_size :
        tmp=(dataset[index]+ dataset[index+1]+ dataset[index+2]+ dataset[index+3]+ dataset[index+4])/5.0
        result.append(tmp)
    else:
      pass

result==movingaverage(y, window_size) 

Try this with valid & same and see whether the math makes sense.

I'd just like to add to Jon's example. To get a reference to your own assembly, you can use:

Assembly myAssembly = Assembly.GetExecutingAssembly();

System.Reflection namespace.

If you want to examine an assembly that you have no reference to, you can use either of these:

Assembly assembly = Assembly.ReflectionOnlyLoad(fullAssemblyName);
Assembly assembly = Assembly.ReflectionOnlyLoadFrom(fileName);

If you intend to instantiate your type once you've found it:

Assembly assembly = Assembly.Load(fullAssemblyName);
Assembly assembly = Assembly.LoadFrom(fileName);

See the Assembly class documentation for more information.

Once you have the reference to the Assembly object, you can use assembly.GetTypes() like Jon already demonstrated.

Use JSON classes for parsing e.g

JSONObject mainObject = new JSONObject(Your_Sring_data);
JSONObject uniObject = mainObject.getJSONObject("university");
String  uniName = uniObject.getString("name");
String uniURL = uniObject.getString("url");

JSONObject oneObject = mainObject.getJSONObject("1");
String id = oneObject.getString("id");
....

In the IntelliJ IDE you just need to type:

""

Then position your cursor inside the quotation marks and paste your string. The IDE will expand it into multiple concatenated lines.

You can calculate the total (and from that the desired percentage) by using a subquery in the FROM clause:

SELECT Name,
       SUM(Value) AS "SUM(VALUE)",
       SUM(Value) / totals.total AS "% of Total"
FROM   table1,
       (
           SELECT Name,
                  SUM(Value) AS total
           FROM   table1
           GROUP BY Name
       ) AS totals
WHERE  table1.Name = totals.Name
AND    Year BETWEEN 2000 AND 2001
GROUP BY Name;

Note that the subquery does not have the WHERE clause filtering the years.

This is solution for AWS JavaScript SDK users, it is almost same for other languages.

Result.data.Count will give you what you are looking for

 apigClient.getitemPost({}, body, {})

    .then(function(result){

        var dataoutput = result.data.Items[0];

        console.log(result.data.Count);
  }).catch( function(result){

});

Use the following pattern.

^\d{10}$

svn copy http://URL/svn/trukSource http://URL/svn/tagDestination -m "Test tag code" 
  $error[0].Exception | Select-object Data

All you have to do change URL path. This command will create new dir "tagDestination". The second line will be let know you the full error details if any occur. Create svn env variable if not created. Can check (Cmd:- set, Powershell:- Get-ChildItem Env:) Default path is "C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe"

Most modern desktop browsers such as Chrome, Mozilla and Internet Explorer support images encoded as data URL. But there are problems displaying data URLs in some mobile browsers: Android Stock Browser and Dolphin Browser won't display embedded JPEGs.

I reccomend you to use the following tools for online base64 encoding/decoding:

• Encode to Base64 format

• Decode from Base64 format

Check the "Format as Data URL" option to format as a Data URL.

Go to wherever you installed Android Studio (for me it's under C:\Users\username\AppData\Local\Android\android-studio\) and open sdk\tools, then run android.bat. From here, update and download any missing build-tools and make sure you update the Android Support Repository and Android Support Library under Extras. Restart Android Studio after the SDK Manager finishes.

It seems that Android Studio completely ignores any installed Android SDK files and keeps a copy of its own. After running an update, everything compiled successfully for me using compile com.android.support:appcompat-v7:18.0.+

The file default.properties is by default read only, changing that worked for me.

You can do like this:

Sub Get_Environmental_Variable()

Dim sHostName As String
Dim sUserName As String

' Get Host Name / Get Computer Name    
sHostName = Environ$("computername")

' Get Current User Name    
sUserName = Environ$("username")

End Sub

I am reading some data from a file using read. Here I am reading data in a 2d char pointer but the method is the same for the 1d also. Just read character by character and do not worry about the exceptions because the condition in the while loop is handling the exceptions :D

  while ( (n = read(fd, buffer,1)) > 0 )
{   

if(buffer[0] == '\n')
{
  r++;
  char**tempData=(char**)malloc(sizeof(char*)*r);

  for(int a=0;a<r;a++)
  {
    tempData[a]=(char*)malloc(sizeof(char)*BUF_SIZE);
    memset(tempData[a],0,BUF_SIZE);
  }

  for(int a=0;a<r-1;a++)
  {
    strcpy(tempData[a],data[a]);
  }

   data=tempData;

   c=0;
}

else
{
  data[r-1][c]=buffer[0];
  c++;
  buffer[1]='\0';
}

   }

A few key changes to Daniel Galasko's answer fixed all my problems. Unfortunately, I don't have enough reputation to comment directly (yet).

In step 1, when using Auto Layout, simply add a single parent UIView to the cell. EVERYTHING inside the cell must be a subview of the parent. That answered all of my problems. While Xcode adds this for UITableViewCells automatically, it doesn't (but it should) for UICollectionViewCells. According to the docs:

To configure the appearance of your cell, add the views needed to present the data item’s content as subviews to the view in the contentView property. Do not directly add subviews to the cell itself.

Then skip step 3 entirely. It isn't needed.

The best practice is using File.separator in the paths.

I have the following in my .bash_profile:

function mark {
    export $1=`pwd`;
}

so anytime I want to remember a directory, I can just type, e.g. mark there .

Then when I want to go back to that location, I just type cd $there

Your question is mixing a few different concepts. You started out saying you wanted to run sites on the same server using the same domain, but in different folders. That doesn't require any special setup. Once you get the single domain running, you just create folders under that docroot.

Based on the rest of your question, what you really want to do is run various sites on the same server with their own domain names.

The best documentation you'll find on the topic is the virtual host documentation in the apache manual.

There are two types of virtual hosts: name-based and IP-based. Name-based allows you to use a single IP address, while IP-based requires a different IP for each site. Based on your description above, you want to use name-based virtual hosts.

The initial error you were getting was due to the fact that you were using different ports than the NameVirtualHost line. If you really want to have sites served from ports other than 80, you'll need to have a NameVirtualHost entry for each port.

Assuming you're starting from scratch, this is much simpler than it may seem.

If you are using 2.3 or earlier, the first thing you need to do is tell Apache that you're going to use name-based virtual hosts.

NameVirtualHost *:80

If you are using 2.4 or later do not add a NameVirtualHost line. Version 2.4 of Apache deprecated the NameVirtualHost directive, and it will be removed in a future version.

Now your vhost definitions:

<VirtualHost *:80>
    DocumentRoot "/home/user/site1/"
    ServerName site1
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/home/user/site2/"
    ServerName site2
</VirtualHost>

You can run as many sites as you want on the same port. The ServerName being different is enough to tell Apache which vhost to use. Also, the ServerName directive is always the domain/hostname and should never include a path.

If you decide to run sites on a port other than 80, you'll always have to include the port number in the URL when accessing the site. So instead of going to http://example.com you would have to go to http://example.com:81

• process.cwd() returns directory where command has been executed (not directory of the node package) if it's has not been changed by 'process.chdir' inside of application.
• __filename returns absolute path to file where it is placed.
• __dirname returns absolute path to directory of __filename.

If you need to load files from your module directory you need to use relative paths.

require('../lib/test');

instead of

var lib  = path.join(path.dirname(fs.realpathSync(__filename)), '../lib');

require(lib + '/test');

It's always relative to file where it called from and don't depend on current work dir.

Instead of writing a function to do this check, you should just be able to use this expression:

(number < 0)

Javascript will evaluate this expression by first trying to convert the left hand side to a number value before checking if it's less than zero, which seems to be what you wanted.

Specifications and details

The behavior for x < y is specified in §11.8.1 The Less-than Operator (<), which uses §11.8.5 The Abstract Relational Comparison Algorithm.

The situation is a lot different if both x and y are strings, but since the right hand side is already a number in (number < 0), the comparison will attempt to convert the left hand side to a number to be compared numerically. If the left hand side can not be converted to a number, the result is false.

Do note that this may give different results when compared to your regex-based approach, but depending on what is it that you're trying to do, it may end up doing the right thing anyway.

• "-0" < 0 is false, which is consistent with the fact that -0 < 0 is also false (see: signed zero).
• "-Infinity" < 0 is true (infinity is acknowledged)
• "-1e0" < 0 is true (scientific notation literals are accepted)
• "-0x1" < 0 is true (hexadecimal literals are accepted)
• " -1 " < 0 is true (some forms of whitespaces are allowed)

For each of the above example, the regex method would evaluate to the contrary (true instead of false and vice versa).

Appendix 1: Conditional operator ?:

It should also be said that statements of this form:

if (someCondition) {
   return valueForTrue;
} else {
   return valueForFalse;
}

can be refactored to use the ternary/conditional ?: operator (§11.12) to simply:

return (someCondition) ? valueForTrue : valueForFalse;

Idiomatic usage of ?: can make the code more concise and readable.

Appendix 2: Type conversion functions

Javascript has functions that you can call to perform various type conversions.

Something like the following:

if (someVariable) {
   return true;
} else {
   return false;
}

Can be refactored using the ?: operator to:

return (someVariable ? true : false);

But you can also further simplify this to:

return Boolean(someVariable);

This calls Boolean as a function (§15.16.1) to perform the desired type conversion. You can similarly call Number as a function (§15.17.1) to perform a conversion to number.

Although the answer I originally marked as chosen is correct and achieves what I asked there is a better way of doing this (which others acknowledged but didn't go into). A composite unique index should be created on the table consisting of fund_id and date.

ALTER TABLE funds ADD UNIQUE KEY `fund_date` (`fund_id`, `date`);

Then when inserting a record add the condition when a conflict is encountered:

INSERT INTO funds (`fund_id`, `date`, `price`)
    VALUES (23, DATE('2013-02-12'), 22.5)
        ON DUPLICATE KEY UPDATE `price` = `price`; --this keeps the price what it was (no change to the table) or:

INSERT INTO funds (`fund_id`, `date`, `price`)
    VALUES (23, DATE('2013-02-12'), 22.5)
        ON DUPLICATE KEY UPDATE `price` = 22.5; --this updates the price to the new value

This will provide much better performance to a sub-query and the structure of the table is superior. It comes with the caveat that you can't have NULL values in your unique key columns as they are still treated as values by MySQL.

You will find this wrapper usefull :)

var pool = mysql.createPool(config.db);

exports.connection = {
    query: function () {
        var queryArgs = Array.prototype.slice.call(arguments),
            events = [],
            eventNameIndex = {};

        pool.getConnection(function (err, conn) {
            if (err) {
                if (eventNameIndex.error) {
                    eventNameIndex.error();
                }
            }
            if (conn) { 
                var q = conn.query.apply(conn, queryArgs);
                q.on('end', function () {
                    conn.release();
                });

                events.forEach(function (args) {
                    q.on.apply(q, args);
                });
            }
        });

        return {
            on: function (eventName, callback) {
                events.push(Array.prototype.slice.call(arguments));
                eventNameIndex[eventName] = callback;
                return this;
            }
        };
    }
};

Require it, use it like this:

db.connection.query("SELECT * FROM `table` WHERE `id` = ? ", row_id)
          .on('result', function (row) {
            setData(row);
          })
          .on('error', function (err) {
            callback({error: true, err: err});
          });

As per the online docs, there is a 64K row limit and you can work out the row size by using:

row length = 1
             + (sum of column lengths)
             + (number of NULL columns + delete_flag + 7)/8
             + (number of variable-length columns)

You need to keep in mind that the column lengths aren't a one-to-one mapping of their size. For example, CHAR(10) CHARACTER SET utf8 requires three bytes for each of the ten characters since that particular encoding has to account for the three-bytes-per-character property of utf8 (that's MySQL's utf8 encoding rather than "real" UTF-8, which can have up to four bytes).

But, if your row size is approaching 64K, you may want to examine the schema of your database. It's a rare table that needs to be that wide in a properly set up (3NF) database - it's possible, just not very common.

If you want to use more than that, you can use the BLOB or TEXT types. These do not count against the 64K limit of the row (other than a small administrative footprint) but you need to be aware of other problems that come from their use, such as not being able to sort using the entire text block beyond a certain number of characters (though this can be configured upwards), forcing temporary tables to be on disk rather than in memory, or having to configure client and server comms buffers to handle the sizes efficiently.

The sizes allowed are:

TINYTEXT          255 (+1 byte  overhead)
TEXT          64K - 1 (+2 bytes overhead)
MEDIUMTEXT    16M - 1 (+3 bytes overhead)
LONGTEXT      4G  - 1 (+4 bytes overhead)

You still have the byte/character mismatch (so that a MEDIUMTEXT utf8 column can store "only" about half a million characters, (16M-1)/3 = 5,592,405) but it still greatly expands your range.

If I am not mistaken, it will be onunload event.

Got a reply from @Vjeux over at the React team:

Normal HTML/CSS:

<div class="something"><span>Something</span></div>
<style>
    .something::after {
    content: '';
    position: absolute;
    -webkit-filter: blur(10px) saturate(2);
}
</style>

React with inline style:

render: function() {
    return (
        <div>
          <span>Something</span>
          <div style={{position: 'absolute', WebkitFilter: 'blur(10px) saturate(2)'}} />
        </div>
    );
},

The trick is that instead of using ::after in CSS in order to create a new element, you should instead create a new element via React. If you don't want to have to add this element everywhere, then make a component that does it for you.

For special attributes like -webkit-filter, the way to encode them is by removing dashes - and capitalizing the next letter. So it turns into WebkitFilter. Note that doing {'-webkit-filter': ...} should also work.

@Dinh Nhat, your setter method looks wrong because you put a primitive type there again and it should be:

public void setClient_os_id(Integer clientOsId) {
client_os_id = clientOsId;
}

    // For use in foreground
    self.locationManager.requestWhenInUseAuthorization()

    if CLLocationManager.locationServicesEnabled() {
        locationManager.delegate = self

    mapView.isScrollEnabled = true

    if let coor = mapView.userLocation.location?.coordinate{
        mapView.setCenter(coor, animated: true)
    }

Write delegate method for location:

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let locValue:CLLocationCoordinate2D = manager.location!.coordinate

    mapView.mapType = MKMapType.standard

    let span = MKCoordinateSpanMake(0.05, 0.05)
    let region = MKCoordinateRegion(center: locValue, span: span)
    mapView.setRegion(region, animated: true)

    let annotation = MKPointAnnotation()
    annotation.coordinate = locValue
    annotation.title = "Javed Multani"
    annotation.subtitle = "current location"
    mapView.addAnnotation(annotation)

    //centerMap(locValue)

It's look like:

Where you don't have a directory defined as a volume in the Dockerfile, the /var/lib/docker/aufs/mnt// will work. But there are cases where the directory within the container is defined as a volume. In this case, the contents under aufs/mnt/*/ and the contents seen by the container are different.

You will need to inspect the container using docker inspect and then, look for volumes. There you will find a mention for something like /var/lib/docker/vfs/dir/fe940b... (the id). You will need to add/modify the files here instead of under aufs/mnt/*.

The confusing part is that the files also appear under /aufs/mnt/*. I spent quite a while scratching my head why changes here didn't work for me. Hope this helps someone.

strcpy is only for C strings. For std::string you copy it like any C++ object.

std::string a = "text";
std::string b = a; // copy a into b

If you want to concatenate strings you can use the + operator:

std::string a = "text";
std::string b = "image";
a = a + b; // or a += b;

You can even do many at once:

std::string c = a + " " + b + "hello";

Although "hello" + " world" doesn't work as you might expect. You need an explicit std::string to be in there: std::string("Hello") + "world"

it's very simple yet tricky but here is what you wanted, hope it's helpful : this function generates a select list from 1990 to 2018 i think this example can help ya, if you want to add any other value just change value of x and y ;)

function dropDown(){
    var start = 1990;
    var today = 2019;
    document.write("<select>");
    for (var i = start ; i <= today; i++)
    document.write("<option>" + i + "</option>");
}
document.write("</select>");

dropDown();

The 2nd parameter in the get call is a config object. You want something like this:

$http
    .get('accept.php', {
        params: {
            source: link,
            category_id: category
        }
     })
     .success(function (data,status) {
          $scope.info_show = data
     });

I would actually suggest you a time saving way to go with this assuming that you know what kind of tags have those attributes.

suppose say a tag xyz has that attritube named "staininfo"..

full_tag = soup.findAll("xyz")

And i wan't you to understand that full_tag is a list

for each_tag in full_tag:
    staininfo_attrb_value = each_tag["staininfo"]
    print staininfo_attrb_value

Thus you can get all the attrb values of staininfo for all the tags xyz

Citing the official javadoc of List.addAll:

Appends all of the elements in the specified collection to the end of
this list, in the order that they are returned by the specified
collection's iterator (optional operation).  The behavior of this
operation is undefined if the specified collection is modified while
the operation is in progress.  (Note that this will occur if the
specified collection is this list, and it's nonempty.)

So you will copy the references of the objects in list to anotherList. Any method that does not operate on the referenced objects of anotherList (such as removal, addition, sorting) is local to it, and therefore will not influence list.

Since you specifically ask for software solutions, and you are using C++, why not use operator overloading to make your own, safe datatypes? For example:

Instead of using uint32_t (and double, int64_t etc), make your own SAFE_uint32_t which contains a multiple (minimum of 3) of uint32_t. Overload all of the operations you want (* + - / << >> = == != etc) to perform, and make the overloaded operations perform independently on each internal value, ie don't do it once and copy the result. Both before and after, check that all of the internal values match. If values don't match, you can update the wrong one to the value with the most common one. If there is no most-common value, you can safely notify that there is an error.

This way it doesn't matter if corruption occurs in the ALU, registers, RAM, or on a bus, you will still have multiple attempts and a very good chance of catching errors. Note however though that this only works for the variables you can replace - your stack pointer for example will still be susceptible.

A side story: I ran into a similar issue, also on an old ARM chip. It turned out to be a toolchain which used an old version of GCC that, together with the specific chip we used, triggered a bug in certain edge cases that would (sometimes) corrupt values being passed into functions. Make sure your device doesn't have any problems before blaming it on radio-activity, and yes, sometimes it is a compiler bug =)

First off, you can circumvent that problem by using std::vector instead of an array. Second, if you put objects of a derived class into an array of a super class, you will experience slicing, but the good news is, your formula will work. Polymorphic collections in C++ are achieved using pointers. There are three major options here:

• normal pointers
• a collection of boost::shared_ptr
• a Boost.Pointer Container

None of the answer for me was working. Actually if you want to watch on nested data with Components being called multiple times. So they are called with different props to identify them. For example <MyComponent chart="chart1"/> <MyComponent chart="chart2"/> My workaround is to create an addionnal vuex state variable, that I manually update to point to the property that was last updated.

Here is a Vuex.ts implementation example:

export default new Vuex.Store({
    state: {
        hovEpacTduList: {},  // a json of arrays to be shared by different components, 
                             // for example  hovEpacTduList["chart1"]=[2,6,9]
        hovEpacTduListChangeForChart: "chart1"  // to watch for latest update, 
                                                // here to access "chart1" update 
   },
   mutations: {
        setHovEpacTduList: (state, payload) => {
            state.hovEpacTduListChangeForChart = payload.chart // we will watch hovEpacTduListChangeForChart
            state.hovEpacTduList[payload.chart] = payload.list // instead of hovEpacTduList, which vuex cannot watch
        },
}

On any Component function to update the store:

    const payload = {chart:"chart1", list: [4,6,3]}
    this.$store.commit('setHovEpacTduList', payload);

Now on any Component to get the update:

    computed: {
        hovEpacTduListChangeForChart() {
            return this.$store.state.hovEpacTduListChangeForChart;
        }
    },
    watch: {
        hovEpacTduListChangeForChart(chart) {
            if (chart === this.chart)  // the component was created with chart as a prop <MyComponent chart="chart1"/> 
                console.log("Update! for", chart, this.$store.state.hovEpacTduList[chart]);
        },
    },

The best approach to this problem is first making the database column UNIQUE

ALTER TABLE table_name ADD UNIQUE KEY

THEN INSERT IGNORE INTO table_name ,the value won't be inserted if it results in a duplicate key/already exists in the table.

There could be a few things happening here. Start by first figuring out your library location:

Sys.getenv("R_LIBS_USER")

or

.libPaths()

We already know yours from the info you gave: C:\Program Files\R\R-3.0.1\library

I believe you have a file in there called: 00LOCK. From ?install.packages:

Note that it is possible for the package installation to fail so badly that the lock directory is not removed: this inhibits any further installs to the library directory (or for --pkglock, of the package) until the lock directory is removed manually.

You need to delete that file. If you had the pacman package installed you could have simply used p_unlock() and the 00LOCK file is removed. You can't install pacman now until the 00LOCK file is removed.

To install pacman use:

install.packages("pacman")

There may be a second issue. This is where you somehow corrupted MASS. This can occur, in my experience, if you try to update a package while it is in use in another R session. I'm sure there's other ways to cause this as well. To solve this problem try:

1. Close out of all R sessions (use task manager to ensure you're truly R session free) Ctrl + Alt + Delete
2. Go to your library location Sys.getenv("R_LIBS_USER"). In your case this is: C:\Program Files\R\R-3.0.1\library
3. Manually delete the MASS package
4. Fire up a vanilla session of R
5. Install MASS via install.packages("MASS")

If any of this works please let me know what worked.

I know the question is old but I found this very helpful http://www.gnuplot.info/demo_canvas/dashcolor.html . So you can choose linetype and linecolor separately but you have to precede everything by "set termoption dash" (worked for me in gnuplot 4.4).

As hadley mentioned there are more effective ways of communicating your message than labels in stacked bar charts. In fact, stacked charts aren't very effective as the bars (each Category) doesn't share an axis so comparison is hard.

It's almost always better to use two graphs in these instances, sharing a common axis. In your example I'm assuming that you want to show overall total and then the proportions each Category contributed in a given year.

library(grid)
library(gridExtra)
library(plyr)

# create a new column with proportions
prop <- function(x) x/sum(x)
Data <- ddply(Data,"Year",transform,Share=prop(Frequency))

# create the component graphics
totals <- ggplot(Data,aes(Year,Frequency)) + geom_bar(fill="darkseagreen",stat="identity") + 
  xlab("") + labs(title = "Frequency totals in given Year")
proportion <- ggplot(Data, aes(x=Year,y=Share, group=Category, colour=Category)) 
+ geom_line() + scale_y_continuous(label=percent_format())+ theme(legend.position = "bottom") + 
  labs(title = "Proportion of total Frequency accounted by each Category in given Year")

# bring them together
grid.arrange(totals,proportion)

This will give you a 2 panel display like this:

If you want to add Frequency values a table is the best format.

Since it's a POD struct, you could always memset it to 0 - this might be the easiest way to get the fields initialized (assuming that is appropriate).

input[value=""], input:not([value])

works with:

<input type="text" />
<input type="text" value="" />

But the style will not change as soon as someone will start typing (you need JS for that).

dbsize() returns the total number of keys.

You can quickly estimate the number of keys matching a given pattern by sampling keys at random, then checking what fraction of them matches the pattern.

Example in python; counting all keys starting with prefix_:

import redis
r = redis.StrictRedis(host = 'localhost', port=6379)
iter=1000
print 'Approximately', r.dbsize() * float(sum([r.randomkey().startswith('prefix_') for i in xrange(iter)])) / iter

Even iter=100 gives a decent estimate in my case, yet is very fast, compared to keys prefix_.

An improvement is to sample 1000 keys on every request, but keep the total count, so that after two requests you'll divide by 2000, after three requests you'll divide by 3000. Thus, if your application is interested in the total number of matching keys fairly often, then every time it will get closer and closer to the true value.

BEGIN TRAN
CREATE TABLE #Table (_Id INT IDENTITY(1,1) ,id INT ,    somedate VARCHAR(100) , somevalue INT)

You can use the html property: http://jsfiddle.net/UBr6c/

My <a href="#" title="This is a<br />test...<br />or not" class="my_tooltip">Tooltip</a> test.

$('.my_tooltip').tooltip({html: true})

To be able to call notify() you need to synchronize on the same object.

synchronized (someObject) {
    someObject.wait();
}

/* different thread / object */
synchronized (someObject) {
    someObject.notify();
}

Tried the below program , With both the approach. 1. With clearing the arraylist obj in for loop 2. creating new New Arraylist in for loop.

List al= new ArrayList();
        for(int i=0;i<100;i++)
        {
            //List al= new ArrayList();

            for(int j=0;j<10;j++)
            {
                al.add(Integer.parseInt("" +j+i));
                //System.out.println("Obj val " +al.get(j));
            }
            //System.out.println("Hashcode : " + al.hashCode());
            al.clear();

        }

and to my surprise. the memory allocation didnt change much.

With New Arraylist approach.

Before loop total free memory: 64,909 ::

After loop total free memory: 64,775 ::

with Clear approach,

Before loop total free memory: 64,909 :: After loop total free memory: 64,765 ::

So this says there is not much difference in using arraylist.clear from memory utilization perspective.

I know its an old thread. But I was having some issues with something similar to this in Maven for Java 8 compiler source. I figured this out with a quick fix mentioned in this article thought I can put it here and maybe can help others:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

There is a great solution for this problem ,You can use the Merge Keyword of Sql

Merge MyTargetTable hba
USING (SELECT Id = 8, Name = 'Product Listing Message') temp 
ON temp.Id = hba.Id
WHEN NOT matched THEN 
INSERT (Id, Name) VALUES (temp.Id, temp.Name);

You can check this before following, below is the sample

IF OBJECT_ID ('dbo.TargetTable') IS NOT NULL
    DROP TABLE dbo.TargetTable
GO

CREATE TABLE dbo.TargetTable
    (
    Id   INT NOT NULL,
    Name VARCHAR (255) NOT NULL,
    CONSTRAINT PK_TargetTable PRIMARY KEY (Id)
    )
GO



INSERT INTO dbo.TargetTable (Name)
VALUES ('Unknown')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('Mapping')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('Update')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('Message')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('Switch')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('Unmatched')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('ProductMessage')
GO


Merge MyTargetTable hba
USING (SELECT Id = 8, Name = 'Listing Message') temp 
ON temp.Id = hba.Id
WHEN NOT matched THEN 
INSERT (Id, Name) VALUES (temp.Id, temp.Name);

If it's just a matter of easy reading, you could always define your own function :

is.not.null <- function(x) !is.null(x)

So you can use it all along your program.

is.not.null(3)
is.not.null(NULL)

Why not simply try this:

var promise = $http.get(url, {
    params: query
}).then(function(response) {
  console.log('Content-Range: ' + response.headers('Content-Range'));
  return response.data;
});

Especially if you want to return the promise so it could be a part of a promises chain.

It seems like sometime during the second half of 2018 many php packages such as php-mysql and phpmyadmin were removed or changed. I faced that same problem too. So you'll have to download it from another source or find out the new packages

The version I'm using I think is the good one, since is the exact same as the Android Developer Docs, except for the name of the string, they used "view" and I used "webview", for the rest is the same

No, it is not.

The one that is new to the N Developer Preview has this method signature:

public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)

The one that is supported by all Android versions, including N, has this method signature:

public boolean shouldOverrideUrlLoading(WebView view, String url)

So why should I do to make it work on all versions?

Override the deprecated one, the one that takes a String as the second parameter.

By example:

# select distinct code from Platform where id in ( select platform__id from Build where product=p)
pl_ids = Build.objects.values('platform__id').filter(product=p)
platforms = Platform.objects.values_list('code', flat=True).filter(id__in=pl_ids).distinct('code')
platforms = list(platforms) if platforms else []

Try putting your text in another div inside your span:

i.e.

<span><div>some text</div></span>

As Alex noted you can use jQuery offset() to get the position relative to the document flow. Use position() for its x,y coordinates relative to the parent.

EDIT: Switched document.ready for window.load because load waits for all of the elements so you get their size instead of simply preparing the DOM. In my experience, load results in fewer incorrectly Javascript positioned elements.

$(window).load(function(){ 
  // Log the position with jQuery
  var position = $('#myDivInQuestion').position();
  console.log('X: ' + position.left + ", Y: " + position.top );
});

There is actually a way to do this with html only. Just sets:

<img src="#" width height="50%">

UPDATE2: more generic vectorized function, which will work for multiple normal and multiple list columns

def explode(df, lst_cols, fill_value='', preserve_index=False):
    # make sure `lst_cols` is list-alike
    if (lst_cols is not None
        and len(lst_cols) > 0
        and not isinstance(lst_cols, (list, tuple, np.ndarray, pd.Series))):
        lst_cols = [lst_cols]
    # all columns except `lst_cols`
    idx_cols = df.columns.difference(lst_cols)
    # calculate lengths of lists
    lens = df[lst_cols[0]].str.len()
    # preserve original index values    
    idx = np.repeat(df.index.values, lens)
    # create "exploded" DF
    res = (pd.DataFrame({
                col:np.repeat(df[col].values, lens)
                for col in idx_cols},
                index=idx)
             .assign(**{col:np.concatenate(df.loc[lens>0, col].values)
                            for col in lst_cols}))
    # append those rows that have empty lists
    if (lens == 0).any():
        # at least one list in cells is empty
        res = (res.append(df.loc[lens==0, idx_cols], sort=False)
                  .fillna(fill_value))
    # revert the original index order
    res = res.sort_index()
    # reset index if requested
    if not preserve_index:        
        res = res.reset_index(drop=True)
    return res

Demo:

Multiple list columns - all list columns must have the same # of elements in each row:

In [134]: df
Out[134]:
   aaa  myid        num          text
0   10     1  [1, 2, 3]  [aa, bb, cc]
1   11     2         []            []
2   12     3     [1, 2]      [cc, dd]
3   13     4         []            []

In [135]: explode(df, ['num','text'], fill_value='')
Out[135]:
   aaa  myid num text
0   10     1   1   aa
1   10     1   2   bb
2   10     1   3   cc
3   11     2
4   12     3   1   cc
5   12     3   2   dd
6   13     4

preserving original index values:

In [136]: explode(df, ['num','text'], fill_value='', preserve_index=True)
Out[136]:
   aaa  myid num text
0   10     1   1   aa
0   10     1   2   bb
0   10     1   3   cc
1   11     2
2   12     3   1   cc
2   12     3   2   dd
3   13     4

Setup:

df = pd.DataFrame({
 'aaa': {0: 10, 1: 11, 2: 12, 3: 13},
 'myid': {0: 1, 1: 2, 2: 3, 3: 4},
 'num': {0: [1, 2, 3], 1: [], 2: [1, 2], 3: []},
 'text': {0: ['aa', 'bb', 'cc'], 1: [], 2: ['cc', 'dd'], 3: []}
})

CSV column:

In [46]: df
Out[46]:
        var1  var2 var3
0      a,b,c     1   XX
1  d,e,f,x,y     2   ZZ

In [47]: explode(df.assign(var1=df.var1.str.split(',')), 'var1')
Out[47]:
  var1  var2 var3
0    a     1   XX
1    b     1   XX
2    c     1   XX
3    d     2   ZZ
4    e     2   ZZ
5    f     2   ZZ
6    x     2   ZZ
7    y     2   ZZ

using this little trick we can convert CSV-like column to list column:

In [48]: df.assign(var1=df.var1.str.split(','))
Out[48]:
              var1  var2 var3
0        [a, b, c]     1   XX
1  [d, e, f, x, y]     2   ZZ

UPDATE: generic vectorized approach (will work also for multiple columns):

Original DF:

In [177]: df
Out[177]:
        var1  var2 var3
0      a,b,c     1   XX
1  d,e,f,x,y     2   ZZ

Solution:

first let's convert CSV strings to lists:

In [178]: lst_col = 'var1' 

In [179]: x = df.assign(**{lst_col:df[lst_col].str.split(',')})

In [180]: x
Out[180]:
              var1  var2 var3
0        [a, b, c]     1   XX
1  [d, e, f, x, y]     2   ZZ

Now we can do this:

In [181]: pd.DataFrame({
     ...:     col:np.repeat(x[col].values, x[lst_col].str.len())
     ...:     for col in x.columns.difference([lst_col])
     ...: }).assign(**{lst_col:np.concatenate(x[lst_col].values)})[x.columns.tolist()]
     ...:
Out[181]:
  var1  var2 var3
0    a     1   XX
1    b     1   XX
2    c     1   XX
3    d     2   ZZ
4    e     2   ZZ
5    f     2   ZZ
6    x     2   ZZ
7    y     2   ZZ

OLD answer:

Inspired by @AFinkelstein solution, i wanted to make it bit more generalized which could be applied to DF with more than two columns and as fast, well almost, as fast as AFinkelstein's solution):

In [2]: df = pd.DataFrame(
   ...:    [{'var1': 'a,b,c', 'var2': 1, 'var3': 'XX'},
   ...:     {'var1': 'd,e,f,x,y', 'var2': 2, 'var3': 'ZZ'}]
   ...: )

In [3]: df
Out[3]:
        var1  var2 var3
0      a,b,c     1   XX
1  d,e,f,x,y     2   ZZ

In [4]: (df.set_index(df.columns.drop('var1',1).tolist())
   ...:    .var1.str.split(',', expand=True)
   ...:    .stack()
   ...:    .reset_index()
   ...:    .rename(columns={0:'var1'})
   ...:    .loc[:, df.columns]
   ...: )
Out[4]:
  var1  var2 var3
0    a     1   XX
1    b     1   XX
2    c     1   XX
3    d     2   ZZ
4    e     2   ZZ
5    f     2   ZZ
6    x     2   ZZ
7    y     2   ZZ

I changed Scanner fin = new Scanner(file); to Scanner fin = new Scanner(new File(file)); and it works perfectly now. I didn't think the difference mattered but there you go.

You can use the positioning method in CSS:

Check the result here....

HTML:

<div class="relativediv">
  <p>
    Make me vertical align as center
  </p>
</div>

CSS:

.relativediv{position:relative;border:1px solid #ddd;height:300px;width:300px}
.relativediv p{position:absolute:top:50%;transfrom:translateY(-50%);}

Hope you use this method too.

The directive can access any attribute that is defined on the same element, even if the directive itself is not the element.

Template:

<div example-directive example-number="99" example-function="exampleCallback()"></div>

Directive:

app.directive('exampleDirective ', function () {
    return {
        restrict: 'A',   // 'A' is the default, so you could remove this line
        scope: {
            callback : '&exampleFunction',
        },
        link: function (scope, element, attrs) {
            var num = scope.$eval(attrs.exampleNumber);
            console.log('number=',num);
            scope.callback();  // calls exampleCallback()
        }
    };
});

fiddle

If the value of attribute example-number will be hard-coded, I suggest using $eval once, and storing the value. Variable num will have the correct type (a number).

The difficulty with DDD samples is that they're often very domain specific and the technical implementation of the resulting system doesn't always show the design decisions and transitions that were made in modelling the domain, which is really at the core of DDD. DDD is much more about the process than it is the code. (as some say, the best DDD sample is the book itself!)

That said, a well commented sample app should at least reveal some of these decisions and give you some direction in terms of matching up your domain model with the technical patterns used to implement it.

You haven't specified which language you're using, but I'll give you a few in a few different languages:

DDDSample - a Java sample that reflects the examples Eric Evans talks about in his book. This is well commented and shows a number of different methods of solving various problems with separate bounded contexts (ie, the presentation layer). It's being actively worked on, so check it regularly for updates.

dddps - Tim McCarthy's sample C# app for his book, .NET Domain-Driven Design with C#

S#arp Architecture - a pragmatic C# example, not as "pure" a DDD approach perhaps due to its lack of a real domain problem, but still a nice clean approach.

With all of these sample apps, it's probably best to check out the latest trunk versions from SVN/whatever to really get an idea of the thinking and technology patterns as they should be updated regularly.

This code worked well with new version (v0.8.12) (2019-05-21)

$('#summernote').summernote({
        callbacks: {
            onImageUpload: function(files) {
                for(let i=0; i < files.length; i++) {
                    $.upload(files[i]);
                }
            }
        },
        height: 500,
    });

    $.upload = function (file) {
        let out = new FormData();
        out.append('file', file, file.name);

        $.ajax({
            method: 'POST',
            url: 'upload.php',
            contentType: false,
            cache: false,
            processData: false,
            data: out,
            success: function (img) {
                $('#summernote').summernote('insertImage', img);
            },
            error: function (jqXHR, textStatus, errorThrown) {
                console.error(textStatus + " " + errorThrown);
            }
        });
    };

PHP Code (upload.php)

if ($_FILES['file']['name']) {
 if (!$_FILES['file']['error']) {
    $name = md5(rand(100, 200));
    $ext = explode('.', $_FILES['file']['name']);
    $filename = $name . '.' . $ext[1];
    $destination = 'images/' . $filename; //change this directory
    $location = $_FILES["file"]["tmp_name"];
    move_uploaded_file($location, $destination);
    echo 'images/' . $filename;//change this URL
 }
 else
 {
  echo  $message = 'Ooops!  Your upload triggered the following error:  '.$_FILES['file']['error'];
 }
}

You can do something like:

function ChckbxsCtrl($scope, $filter) {
    $scope.chkbxs = [{
        label: "Led Zeppelin",
        val: false
    }, {
        label: "Electric Light Orchestra",
        val: false
    }, {
        label: "Mark Almond",
        val: false
    }];

    $scope.$watch("chkbxs", function(n, o) {
        var trues = $filter("filter")(n, {
            val: true
        });
        $scope.flag = trues.length;
    }, true);
}

And a template:

<div ng-controller="ChckbxsCtrl">
    <div ng-repeat="chk in chkbxs">
        <input type="checkbox" ng-model="chk.val" />
        <label>{{chk.label}}</label>
    </div>
    <div ng-show="flag">I'm ON when band choosed</div>
</div>

Working: http://jsfiddle.net/cherniv/JBwmA/

UPDATE: Or you can go little bit different way , without using $scope's $watch() method, like:

$scope.bandChoosed = function() {
    var trues = $filter("filter")($scope.chkbxs, {
        val: true
    });
    return trues.length;
}

And in a template do:

<div ng-show="bandChoosed()">I'm ON when band choosed</div>

I had to implement a custom solution because it's not as simple as you might think. My solution is based on stack trace inspection (inspect.stack()) + sys.path and is working fine no matter the location of the python module in which the function is invoked nor the interpreter (I tried by running it in PyCharm, in a poetry shell and other...). This is the full implementation with comments:

def get_project_root_dir() -> str:
    """
    Returns the name of the project root directory.

    :return: Project root directory name
    """

    # stack trace history related to the call of this function
    frame_stack: [FrameInfo] = inspect.stack()

    # get info about the module that has invoked this function
    # (index=0 is always this very module, index=1 is fine as long this function is not called by some other
    # function in this module)
    frame_info: FrameInfo = frame_stack[1]

    # if there are multiple calls in the stacktrace of this very module, we have to skip those and take the first
    # one which comes from another module
    if frame_info.filename == __file__:
        for frame in frame_stack:
            if frame.filename != __file__:
                frame_info = frame
                break

    # path of the module that has invoked this function
    caller_path: str = frame_info.filename

    # absolute path of the of the module that has invoked this function
    caller_absolute_path: str = os.path.abspath(caller_path)

    # get the top most directory path which contains the invoker module
    paths: [str] = [p for p in sys.path if p in caller_absolute_path]
    paths.sort(key=lambda p: len(p))
    caller_root_path: str = paths[0]

    if not os.path.isabs(caller_path):
        # file name of the invoker module (eg: "mymodule.py")
        caller_module_name: str = Path(caller_path).name

        # this piece represents a subpath in the project directory
        # (eg. if the root folder is "myproject" and this function has ben called from myproject/foo/bar/mymodule.py
        # this will be "foo/bar")
        project_related_folders: str = caller_path.replace(os.sep + caller_module_name, '')

        # fix root path by removing the undesired subpath
        caller_root_path = caller_root_path.replace(project_related_folders, '')

    dir_name: str = Path(caller_root_path).name

    return dir_name

Consider the outcome of the tool 'stat':

  File: `infolog.txt'
  Size: 694         Blocks: 8          IO Block: 4096   regular file
Device: 801h/2049d  Inode: 11635578    Links: 1
Access: (0644/-rw-r--r--)  Uid: ( 1000/     fdr)   Gid: ( 1000/     fdr)
Access: 2009-01-01 22:04:15.000000000 -0800
Modify: 2009-01-01 22:05:05.000000000 -0800
Change: 2009-01-01 22:05:05.000000000 -0800

You can see here the three dates for Access/modify/change. There is no created date. You can only really be sure when the file contents were modified (the "modify" field) or its inode changed (the "change" field).

Examples of when both fields get updated:

"Modify" will be updated if someone concatenated extra information to the end of the file.

"Change" will be updated if someone changed permissions via chmod.

If you require to get only one record from database table using codeigniter query then you can do it using row(). we can easily return one row from database in codeigniter.

$data = $this->db->get("items")->row();

Try this:

public static void main(String[] args) {
    String str = "My name is Milan, people know me as Milan Vasic.";

    Pattern p = Pattern.compile("(Milan)(?! Vasic)");
    Matcher m = p.matcher(str);

    StringBuffer sb = new StringBuffer();

    while(m.find()) {
        m.appendReplacement(sb, "Milan Vasic");
    }

    m.appendTail(sb);
    System.out.println(sb);
}

I think you are getting confused with your site Authentication and SSL.

If you need to get your site into SSL, then you would need to install a SSL certificate into your web server. You can buy a certificate for yourself from one of the places like Symantec etc. The certificate would contain your public/private key pair, along with other things.

You wont need to do anything in your source code, and you can still continue to use your Form Authntication (or any other) in your site. Its just that, any data communication that takes place between the web server and the client will encrypted and signed using your certificate. People would use secure-HTTP (https://) to access your site.

I had this problem i.e. works fine when pasted into browser but 505s when done through java. It was simply the spaces that needed to be escaped/encoded.

Two Answers

1. Answer to the asked question.

2. A simple change equals a better way!

Answer 1 - Pass the Vars Array to the __construct() in a class, you could also leave the construct empty and pass the Arrays through your functions instead.

<?php

// Create an Array with all needed Sub Arrays Example: 
// Example Sub Array 1
$content_arrays["modals"]= array();
// Example Sub Array 2
$content_arrays["js_custom"] = array();

// Create a Class
class Array_Pushing_Example_1 {

    // Public to access outside of class
    public $content_arrays;

    // Needed in the class only
    private $push_value_1;
    private $push_value_2;
    private $push_value_3;
    private $push_value_4;  
    private $values;
    private $external_values;

    // Primary Contents Array as Parameter in __construct
    public function __construct($content_arrays){

        // Declare it
        $this->content_arrays = $content_arrays;

    }

    // Push Values from in the Array using Public Function
    public function array_push_1(){

        // Values
        $this->push_values_1 = array(1,"2B or not 2B",3,"42",5);
        $this->push_values_2 = array("a","b","c");

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_1 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_2 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

    // GET Push Values External to the Class with Public Function
    public function array_push_2($external_values){

        $this->push_values_3 = $external_values["values_1"];
        $this->push_values_4 = $external_values["values_2"];

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_3 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_4 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

}

// Start the Class with the Contents Array as a Parameter
$content_arrays = new Array_Pushing_Example_1($content_arrays);

// Push Internal Values to the Arrays
$content_arrays->content_arrays = $content_arrays->array_push_1();

// Push External Values to the Arrays
$external_values = array();
$external_values["values_1"] = array("car","house","bike","glass");
$external_values["values_2"] = array("FOO","foo");
$content_arrays->content_arrays = $content_arrays->array_push_2($external_values);

// The Output
echo "Array Custom Content Results 1";
echo "<br>";
echo "<br>";

echo "Modals - Count: ".count($content_arrays->content_arrays["modals"]);
echo "<br>";
echo "-------------------";
echo "<br>";

// Get Modals Array Results
foreach($content_arrays->content_arrays["modals"] as $modals){

    echo $modals;
    echo "<br>";

}

echo "<br>";
echo "JS Custom - Count: ".count($content_arrays->content_arrays["js_custom"]);
echo "<br>";
echo "-------------------";
echo "<br>";

// Get JS Custom Array Results
foreach($content_arrays->content_arrays["js_custom"] as $js_custom){

    echo $js_custom;
    echo "<br>";


}

echo "<br>";

?>

Answer 2 - A simple change however would put it inline with modern standards. Just declare your Arrays in the Class.

<?php

// Create a Class
class Array_Pushing_Example_2 {

    // Public to access outside of class
    public $content_arrays;

    // Needed in the class only
    private $push_value_1;
    private $push_value_2;
    private $push_value_3;
    private $push_value_4;  
    private $values;
    private $external_values;

    // Declare Contents Array and Sub Arrays in __construct
    public function __construct(){

        // Declare them
        $this->content_arrays["modals"] = array();
        $this->content_arrays["js_custom"] = array();

    }

    // Push Values from in the Array using Public Function
    public function array_push_1(){

        // Values
        $this->push_values_1 = array(1,"2B or not 2B",3,"42",5);
        $this->push_values_2 = array("a","b","c");

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_1 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_2 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

    // GET Push Values External to the Class with Public Function
    public function array_push_2($external_values){

        $this->push_values_3 = $external_values["values_1"];
        $this->push_values_4 = $external_values["values_2"];

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_3 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_4 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

}

// Start the Class without the Contents Array as a Parameter
$content_arrays = new Array_Pushing_Example_2();

// Push Internal Values to the Arrays
$content_arrays->content_arrays = $content_arrays->array_push_1();

// Push External Values to the Arrays
$external_values = array();
$external_values["values_1"] = array("car","house","bike","glass");
$external_values["values_2"] = array("FOO","foo");
$content_arrays->content_arrays = $content_arrays->array_push_2($external_values);

// The Output
echo "Array Custom Content Results 1";
echo "<br>";
echo "<br>";

echo "Modals - Count: ".count($content_arrays->content_arrays["modals"]);
echo "<br>";
echo "-------------------";
echo "<br>";

// Get Modals Array Results
foreach($content_arrays->content_arrays["modals"] as $modals){

    echo $modals;
    echo "<br>";

}

echo "<br>";
echo "JS Custom - Count: ".count($content_arrays->content_arrays["js_custom"]);
echo "<br>";
echo "-------------------";
echo "<br>";

// Get JS Custom Array Results
foreach($content_arrays->content_arrays["js_custom"] as $js_custom){

    echo $js_custom;
    echo "<br>";


}

echo "<br>";

?>

Both options output the same information and allow a function to push and retrieve information from an Array and sub Arrays to any place in the code(Given that the data has been pushed first). The second option gives more control over how the data is used and protected. They can be used as is just modify to your needs but if they were used to extend a Controller they could share their values among any of the Classes the Controller is using. Neither method requires the use of a Global(s).

Output:

Array Custom Content Results

Modals - Count: 5

a

b

c

FOO

foo

JS Custom - Count: 9

1

2B or not 2B

3

42

5

car

house

bike

glass

This looks like an old thread but there is one more variant of how we can set an environment variable in the Gradle task.

task runSomeRandomTask(type: NpmTask, dependsOn: [npmInstall]) {
    environment = [ 'NODE_ENV': 'development', BASE_URL: '3000' ]
    args = ['run']
}

The above Gradle task integrates the Gradle and npm tasks.

This way we can pass multiple environment variables. Hope this helps to broaden the understanding which the answers above have already provided. Cheers!!

use google Guava and do it in 2 lines:

import java.util.Map;
import com.google.common.base.Splitter;

public class Parser {
    public static void main(String... args) {
        String uri = "https://google.com.ua/oauth/authorize?client_id=SS&response_type=code&scope=N_FULL&access_type=offline&redirect_uri=http://localhost/Callback";
        String query = uri.split("\\?")[1];
        final Map<String, String> map = Splitter.on('&').trimResults().withKeyValueSeparator('=').split(query);
        System.out.println(map);
    }
}

which gives you

{client_id=SS, response_type=code, scope=N_FULL, access_type=offline, redirect_uri=http://localhost/Callback}

In my case I had an image in different folders (with same name) for supporting different dpi and device sizes. All images had same name except one of them. It was mistyped and once I renamed it like other names, it resolved my issue.

Ok, I think I have worked out "git stash unapply". It's more complex than git apply --reverse because you need reverse merging action in case there was any merging done by the git stash apply.

The reverse merge requires that all current changes be pushed into the index:

• git add -u

Then invert the merge-recursive that was done by git stash apply:

• git merge-recursive stash@{0}: -- $(git write-tree) stash@{0}^1

Now you will be left with just the non-stash changes. They will be in the index. You can use git reset to unstage your changes if you like.

Given that your original git stash apply failed I assume the reverse might also fail since some of the things it wants to undo did not get done.

Here's an example showing how the working copy (via git status) ends up clean again:

 $ git status
# On branch trunk
nothing to commit (working directory clean)
 $ git stash apply
Auto-merging foo.c
# On branch trunk
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#       modified:   foo.c
#
no changes added to commit (use "git add" and/or "git commit -a")
 $ git add -u
 $ git merge-recursive stash@{0}: -- $(git write-tree) stash@{0}^1
Auto-merging foo.c
 $ git status
# On branch trunk
nothing to commit (working directory clean)

For Laravel 5.x, use $storage_path = storage_path().

From the Laravel 5.0 docs:

storage_path

Get the fully qualified path to the storage directory.

Note also that, for Laravel 5.1 and above, per the Laravel 5.1 docs:

You may also use the storage_path function to generate a fully qualified path to a given file relative to the storage directory:

$path = storage_path('app/file.txt');

I have found that so many interviews are asking for this so I implemented a really quite simple and understandable solution. First I generate all the possible combinations, and from there, you can do whatever you want. Check this out:

public static void main(String[] args) {
        int[] numbers = new int[]{1, 2, 3, 4, 5};
        List<int[]> allPossibleCombinatiosForNumbers = new ArrayList<>();
        for (int i = 2; i < numbers.length; i++) {
            allPossibleCombinatiosForNumbers.addAll(getCombinationsOfNElements(numbers, i));
        }
        for (int[] combination : allPossibleCombinatiosForNumbers) {
            printArray(combination);
            printArrayIfNumbersSumExpectedValue(combination, 6);
        }
    }


    private static List<int[]> getCombinationsOfNElements(int[] numbers, int n) {
        int elementsKnown = n - 1;
        List<int[]> allCombinationsOfNElements = new ArrayList<>();
        for (int i = 0; i < numbers.length - elementsKnown; i++) {
            int[] combination = new int[n];
            for (int j = 0; j < n; j++) {
                combination[j] = numbers[i + j];
            }
            allCombinationsOfNElements.addAll(generationCombinations(combination, i + elementsKnown, numbers));
        }
        return allCombinationsOfNElements;
    }

    private static List<int[]> generationCombinations(int[] knownElements, int index, int[] numbers) {
        List<int[]> combinations = new ArrayList<>();
        for (int i = index; i < numbers.length; i++) {
            int[] combinationComplete = Arrays.copyOf(knownElements, knownElements.length);
            combinationComplete[knownElements.length - 1] = numbers[i];
            combinations.add(combinationComplete);
        }
        return combinations;
    }

    private static void printArray(int[] numbers) {
        System.out.println();
        for (int i = 0; i < numbers.length; i++) {
            System.out.print(numbers[i] + " ");
        }
    }

    private static void printArrayIfNumbersSumExpectedValue(int[] numbers, int expectedValue) {
        int total = 0;
        for (int i = 0; i < numbers.length; i++) {
            total += numbers[i];
        }
        if (total == expectedValue) {
            System.out.print("\n ----- Here is a combination you are looking for -----");
            printArray(numbers);
            System.out.print("\n -------------------------------");
        }
    }

I know you are not after array_unique(). However, you will not find a magical obvious function nor will writing one be faster than making use of the native functions.

I propose:

function array_has_dupes($array) {
   // streamline per @Felix
   return count($array) !== count(array_unique($array));
}

Adjust the second parameter of array_unique() to meet your comparison needs.

If you are looking for answer in string values , try this

var check = moment('date/utc format');
day = check.format('dddd') // => ('Monday' , 'Tuesday' ----)
month = check.format('MMMM') // => ('January','February.....)
year = check.format('YYYY') // => ('2012','2013' ...)  

You have enabled CORS and enabled Access-Control-Allow-Origin : * in the server.If still you get GET method working and POST method is not working then it might be because of the problem of Content-Type and data problem.

First AngularJS transmits data using Content-Type: application/json which is not serialized natively by some of the web servers (notably PHP). For them we have to transmit the data as Content-Type: x-www-form-urlencoded

Example :-

        $scope.formLoginPost = function () {
            $http({
                url: url,
                method: "POST",
                data: $.param({ 'username': $scope.username, 'Password': $scope.Password }),
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
            }).then(function (response) {
                // success
                console.log('success');
                console.log("then : " + JSON.stringify(response));
            }, function (response) { // optional
                // failed
                console.log('failed');
                console.log(JSON.stringify(response));
            });
        };

Note : I am using $.params to serialize the data to use Content-Type: x-www-form-urlencoded. Alternatively you can use the following javascript function

function params(obj){
    var str = "";
    for (var key in obj) {
        if (str != "") {
            str += "&";
        }
        str += key + "=" + encodeURIComponent(obj[key]);
    }
    return str;
}

and use params({ 'username': $scope.username, 'Password': $scope.Password }) to serialize it as the Content-Type: x-www-form-urlencoded requests only gets the POST data in username=john&Password=12345 form.

try using %% to print % sign .

Code for Python 3.6.1

print("This first text and " , end="")

print("second text will be on the same line")

print("Unlike this text which will be on a newline")

Output

>>>
This first text and second text will be on the same line
Unlike this text which will be on a newline

You should read that, it's still valid.

You'll adapt the function you use depending on your needs.

Basically:

• if you already load all entries, say User.all, then you should use length to avoid another db query

• if you haven't anything loaded, use count to make a count query on your db

• if you don't want to bother with these considerations, use size which will adapt

Another option is to use mongoose-history plugin.

let mongoose = require('mongoose');
let mongooseHistory = require('mongoose-history');
let Schema = mongoose.Schema;

let MySchema = Post = new Schema({
    title: String,
    status: Boolean
});

MySchema.plugin(mongooseHistory);
// The plugin will automatically create a new collection with the schema name + "_history".
// In this case, collection with name "my_schema_history" will be created.

Did you try passwd -d root? Most likely, this will do what you want.

You can also manually edit /etc/shadow: (Create a backup copy. Be sure that you can log even if you mess up, for example from a rescue system.) Search for "root". Typically, the root entry looks similar to

root:$X$SK5xfLB1ZW:0:0...

There, delete the second field (everything between the first and second colon):

root::0:0...

Some systems will make you put an asterisk (*) in the password field instead of blank, where a blank field would allow no password (CentOS 8 for example)

root:*:0:0...

Save the file, and try logging in as root. It should skip the password prompt. (Like passwd -d, this is a "no password" solution. If you are really looking for a "blank password", that is "ask for a password, but accept if the user just presses Enter", look at the manpage of mkpasswd, and use mkpasswd to create the second field for the /etc/shadow.)

FileStream fs = new FileStream(txtSourcePath.Text,FileMode.Open, FileAccess.Read);
using(StreamReader sr = new StreamReader(fs))
{
   using (StreamWriter sw = new StreamWriter(Destination))
   {
            sw.writeline("Your text");
    }
}

Alternatively, you can use npx which comes along with the npm > 5.6.

npx bower install

When you create your table, put your td with class = "suma"

$(function(){   

   //funcion suma todo

   var sum = 0;
   $('.suma').each(function(x,y){
       sum += parseInt($(this).text());                                   
   })           
   $('#lblTotal').text(sum);   

   // funcion suma por check                                           

    $( "input:checkbox").change(function(){
    if($(this).is(':checked')){     
        $(this).parent().parent().find('td:last').addClass('suma2');
   }else{       
        $(this).parent().parent().find('td:last').removeClass('suma2');
   }    
   suma2Total();                                                           
   })                                                      

   function suma2Total(){
      var sum2 = 0;
      $('.suma2').each(function(x,y){
        sum2 += parseInt($(this).text());       
      })
      $('#lblTotal2').text(sum2);                                              
   }

Here I want my no to limit in 4 digit like if it is 1 it should show as 0001,if it 11 it should show as 0011..Below are the code.

        reciptno=1;//Pass only integer.

        string formatted = string.Format("{0:0000}", reciptno);

        TxtRecNo.Text = formatted;//Output=0001..

I implemented this code to generate Money receipt no.

A somewhat different approach (at least on Android) is to use the IntDef annotation to combine a set of int constants

@IntDef({NOTAX, SALESTAX, IMPORTEDTAX})
@interface TAX {}
int NOTAX = 0;
int SALESTAX = 10;
int IMPORTEDTAX = 5;

Use as function parameter:

void computeTax(@TAX int taxPercentage){...} 

or in a variable declaration:

@TAX int currentTax = IMPORTEDTAX;

UPDATE 7/3/2014: As of now, jquery-latest.js is no longer being updated. From the jQuery blog:

We know that http://code.jquery.com/jquery-latest.js is abused because of the CDN statistics showing it’s the most popular file. That wouldn’t be the case if it was only being used by developers to make a local copy.

We have decided to stop updating this file, as well as the minified copy, keeping both files at version 1.11.1 forever.

The Google CDN team has joined us in this effort to prevent inadvertent web breakage and no longer updates the file at http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js. That file will stay locked at version 1.11.1 as well.

The following, now moot, answer is preserved here for historical reasons.

Don't do this. Seriously, don't.

Linking to major versions of jQuery does work, but it's a bad idea -- whole new features get added and deprecated with each decimal update. If you update jQuery automatically without testing your code COMPLETELY, you risk an unexpected surprise if the API for some critical method has changed.

Here's what you should be doing: write your code using the latest version of jQuery. Test it, debug it, publish it when it's ready for production.

Then, when a new version of jQuery rolls out, ask yourself: Do I need this new version in my code? For instance, is there some critical browser compatibility that didn't exist before, or will it speed up my code in most browsers?

If the answer is "no", don't bother updating your code to the latest jQuery version. Doing so might even add NEW errors to your code which didn't exist before. No responsible developer would automatically include new code from another site without testing it thoroughly.

There's simply no good reason to ALWAYS be using the latest version of jQuery. The old versions are still available on the CDNs, and if they work for your purposes, then why bother replacing them?

A secondary, but possibly more important, issue is caching. Many people link to jQuery on a CDN because many other sites do, and your users have a good chance of having that version already cached.

The problem is, caching only works if you provide a full version number. If you provide a partial version number, far-future caching doesn't happen -- because if it did, some users would get different minor versions of jQuery from the same URL. (Say that the link to 1.7 points to 1.7.1 one day and 1.7.2 the next day. How will the browser make sure it's getting the latest version today? Answer: no caching.)

In fact here's a breakdown of several options and their expiration settings...

http://code.jquery.com/jquery-latest.min.js (no cache)

http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js (1 hour)

http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js (1 hour)

http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js (1 year)

So, by linking to jQuery this way, you're actually eliminating one of the major reasons to use a CDN in the first place.

http://code.jquery.com/jquery-latest.min.js may not always give you the version you expect, either. As of this writing, it links to the latest version of jQuery 1.x, even though jQuery 2.x has been released as well. This is because jQuery 1.x is compatible with older browsers including IE 6/7/8, and jQuery 2.x is not. If you want the latest version of jQuery 2.x, then (for now) you need to specify that explicitly.

The two versions have the same API, so there is no perceptual difference for compatible browsers. However, jQuery 1.x is a larger download than 2.x.

Unfortunately, you can only turn on all invisible (whitespace) characters at the same time. I suggest you file an enhancement request but I doubt they will pick it up.

The text component in Eclipse is very complicated as it is and they are not keen on making them even worse.

[UPDATE] This has been fixed in Eclipse 3.7: Go to Window > Preferences > General > Editors > Text Editors

Click on the link "whitespace characters" to fine tune what should be shown.

Here's a way to upload your images using the formidable package, which is recommended over bodyParser in later versions of Express. This also includes the ability to resize your images on the fly:

From my website: Uploading and Resizing Images (on the fly) With Node.js and Express.

Here's the gist:

var express = require("express"),
app = express(),
formidable = require('formidable'),
util = require('util')
fs   = require('fs-extra'),
qt   = require('quickthumb');

// Use quickthumb
app.use(qt.static(__dirname + '/'));

app.post('/upload', function (req, res){
  var form = new formidable.IncomingForm();
  form.parse(req, function(err, fields, files) {
    res.writeHead(200, {'content-type': 'text/plain'});
    res.write('received upload:\n\n');
    res.end(util.inspect({fields: fields, files: files}));
  });

  form.on('end', function(fields, files) {
    /* Temporary location of our uploaded file */
    var temp_path = this.openedFiles[0].path;
    /* The file name of the uploaded file */
    var file_name = this.openedFiles[0].name;
    /* Location where we want to copy the uploaded file */
    var new_location = 'uploads/';

    fs.copy(temp_path, new_location + file_name, function(err) {  
      if (err) {
        console.error(err);
      } else {
        console.log("success!")
      }
    });
  });
});

// Show the upload form 
app.get('/', function (req, res){
  res.writeHead(200, {'Content-Type': 'text/html' });
  /* Display the file upload form. */
  form = '<form action="/upload" enctype="multipart/form-data" method="post">'+ '<input name="title" type="text" />
  '+ '<input multiple="multiple" name="upload" type="file" />
  '+ '<input type="submit" value="Upload" />'+ '</form>';
  res.end(form); 
}); 
app.listen(8080);

NOTE: This requires Image Magick for the quick thumb resizing.

if objFolderItem is Nothing when you call

objFolder.GetDetailsOf(objFolderItem, i)

the string returned is the name of the property, rather than its (undefined) value e.g. when i=3 it returns "Date modified"

Doing it for all 288 values of I makes it clear why most cause it to return blank for most filetypes e.g i=175 is "Horizontal resolution"

This fixes the box dead center on the screen:

This worked for me. 1. Click on Window-> Preferences -> Installed JRE. 2. Check if you reference is for JDK as shown in the image below.

If not, Click on Add-> Standard VM -> Give the JDK path by selecting the directory and click on finish as shown in the image

3. Last step, click on Installed JREs -> Execution Environments -> select your JDE as shown in the image below

4. Maven -> Clean

Try the -i flag (or --ignore-errors). The documentation seems to suggest a more robust way to achieve this, by the way:

To ignore errors in a command line, write a - at the beginning of the line's text (after the initial tab). The - is discarded before the command is passed to the shell for execution.

For example,

clean:
  -rm -f *.o

This causes rm to continue even if it is unable to remove a file.

All examples are with rm, but are applicable to any other command you need to ignore errors from (i.e. mkdir).

On my particular case i needed too many times to change for the same directory. So on my .bashrc (I use ubuntu) i've added the

1 -

$ nano ~./bashrc

 function switchp
 {
    cd /home/tree/projects/$1
 }

2-

$ source ~/.bashrc

3 -

$ switchp java

Directly it will do: cd /home/tree/projects/java

Hope that helps!

You could use PIL to create (and display) an image:

from PIL import Image
import numpy as np

w, h = 512, 512
data = np.zeros((h, w, 3), dtype=np.uint8)
data[0:256, 0:256] = [255, 0, 0] # red patch in upper left
img = Image.fromarray(data, 'RGB')
img.save('my.png')
img.show()

@echo off
echo Press any key to exit . . .

SELECT * FROM tablename WHERE visible=1 ORDER BY CASE WHEN `position` = 0 THEN 'a' END , position ASC

This is for anyone that is trying to get a list of all files in a folder and its sub-folders and save it in a text document. Below is the full code including the “using” statements, “namespace”, “class”, “methods” etc. I tried commenting as much as possible throughout the code so you could understand what each part is doing. This will create a text document that contains a list of all files in all folders and sub-folders of any given root folder. After all, what good is a list (like in Console.WriteLine) if you can’t do something with it. Here I have created a folder on the C drive called “Folder1” and created a folder inside that one called “Folder2”. Next I filled folder2 with a bunch of files, folders and files and folders within those folders. This example code will get all the files and create a list in a text document and place that text document in Folder1. Caution: you shouldn’t save the text document to Folder2 (the folder you are reading from), that would be just bad practice. Always save it to another folder.
I hope this helps someone down the line.

I do the following:

1. put #! /usr/bin/env python3 at top of script
2. chmod u+x file.py
3. Change .py to .command in file name

This essentially turns the file into a bash executable. When you double-click it, it should run. This works in Unix-based systems.

If you want to use a default value when null or empty (e.g. when retrieving from config file and the value does not exist) and throw an exception when the string or number does not match any of the enum values. Beware of caveat in Timo's answer though (https://stackoverflow.com/a/34267134/2454604).

    public static T ParseEnum<T>(this string s, T defaultValue, bool ignoreCase = false) 
        where T : struct, IComparable, IConvertible, IFormattable//If C# >=7.3: struct, System.Enum 
    {
        if ((s?.Length ?? 0) == 0)
        {
            return defaultValue;
        }

        var valid = Enum.TryParse<T>(s, ignoreCase, out T res);

        if (!valid || !Enum.IsDefined(typeof(T), res))
        {
            throw new InvalidOperationException(
                $"'{s}' is not a valid value of enum '{typeof(T).FullName}'!");
        }
        return res;
    }

Another option is:

• Project > Properties > Java Build Path
• Select Libraries tab
• Select the troublesome JRE entry
• Click Edit button
• Choose an alternate JRE
• Click Finish button

Pointing the project at your installed JRE might be a better choice than renaming your JRE to match the old project code.

You can use Google Gson like this

UserEntity user = new UserEntity();
user.setUserName("UserName");
user.setUserAge(18);

Gson gson = new Gson();
String jsonStr = gson.toJson(user);

Because your code contains if __name__ == "__main__", which doesn't be imported as a package, you'd better use sys.path.append() to solve the problem.

Echo is so nineties and so fraught with perils that its use should result in core dumps no less than 4GB. Seriously, echo's problems were the reason why the Unix Standardization process finally invented the printf utility, doing away with all the problems.

So to get a newline in a string:

FOO="hello
world"
BAR=$(printf "hello\nworld\n") # Alternative; note: final newline is deleted
printf '<%s>\n' "$FOO"
printf '<%s>\n' "$BAR"

There! No SYSV vs BSD echo madness, everything gets neatly printed and fully portable support for C escape sequences. Everybody please use printf now and never look back.

If you want to re-filter the json data you can use following method. Given example is getting all document data from couchdb.

{
    Gson gson = new Gson();
    String resultJson = restTemplate.getForObject(url+"_all_docs?include_docs=true", String.class);
    JSONObject object =  (JSONObject) new JSONParser().parse(resultJson);
    JSONArray rowdata = (JSONArray) object.get("rows");   
    List<Object>list=new ArrayList<Object>();   
    for(int i=0;i<rowdata.size();i++) {
        JSONObject index = (JSONObject) rowdata.get(i);
        JSONObject data = (JSONObject) index.get("doc");
        list.add(data);      
    }
    // convert your list to json
    String devicelist = gson.toJson(list);
    return devicelist;
}

Apply following some steps:

Go to xcode_preferences->Then select font and colors->select all the text options->click on the font section and change fonts u want

Cursor c = scoreDb.query(Table_Name, score, null, null, null, null, Column+" DESC");

Try this

In JPA 2.0 if you want to delete an address if you removed it from a User entity you can add orphanRemoval=true (instead of CascadeType.REMOVE) to your @OneToMany.

More explanation between orphanRemoval=true and CascadeType.REMOVE is here.

In your .pro add

CONFIG          += console

For WinRT (Windows Store App)

using Windows.UI;
using Windows.UI.Xaml.Media;

    public static Brush ColorToBrush(string color) // color = "#E7E44D"
    {
        color = color.Replace("#", "");
        if (color.Length == 6)
        {
            return new SolidColorBrush(ColorHelper.FromArgb(255,
                byte.Parse(color.Substring(0, 2), System.Globalization.NumberStyles.HexNumber),
                byte.Parse(color.Substring(2, 2), System.Globalization.NumberStyles.HexNumber),
                byte.Parse(color.Substring(4, 2), System.Globalization.NumberStyles.HexNumber)));
        }
        else
        {
            return null;
        }
    }

This actually works for me:

Per the README.SSO that comes with the jtdsd distribution:

In order for Single Sign On to work, jTDS must be able to load the native SPPI library ntlmauth.dll. Place this DLL anywhere in the system path (defined by the PATH system variable) and you're all set.

I placed it in my jre/bin folder

I configured a port dedicated the sql server instance (2302) to alleviate the need for an instance name - just something I do. lportal is my database name.

jdbc.default.url=jdbc:jtds:sqlserver://192.168.0.147:2302/lportal;useNTLMv2=true;domain=mydomain.local

You will have to add -x test

e.g. ./gradlew build -x test

or

gradle build -x test

I had the same problem on CentOS and this worked for me (version: 8.0.11):

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'

This should display 'Tue':

new SimpleDateFormat("EEE").format(new Date());

This should display 'Tuesday':

new SimpleDateFormat("EEEE").format(new Date());

This should display 'T':

new SimpleDateFormat("EEEEE").format(new Date());

So your specific example would be:

new SimpleDateFormat("yyyy-MM-EEE").format(new Date());

Well, most other answers here refer to

sort -n

However, I'm not sure this works for negative numbers. Here are the results I get with sort version 6.10 on Fedora 9.

Input file:

-0.907928466796875
-0.61614990234375
1.135406494140625
0.48614501953125
-0.4140167236328125

Output:

-0.4140167236328125
0.48614501953125
-0.61614990234375
-0.907928466796875
1.135406494140625

Which is obviously not ordered by numeric value.

Then, I guess that a more precise answer would be to use sort -n but only if all the values are positive.

P.S.: Using sort -g returns just the same results for this example

Edit:

Looks like the locale settings affect how the minus sign affects the order (see here). In order to get proper results I just did:

LC_ALL=C sort -n filename.txt

Here what I DO on MY PC I install all software that i usually used in G: partian not C: if my operating system is fall (win 10) , Do not need to reinstall them again and lost time , Then How windows work it update PATH automatic if you install any new programe or pice of softwore ,

SO

I must update PATH like these HERE! all my software i usually used 1- I created folder called Programe Files 2- I install all my programe data in these folder 3-and then going to PATH and add it Dont forget ;

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;G:\HashiCorp\Vagrant\bin;G:\xampp\php;G:\xampp\mysql\bin;G:\Program Files (x86)\heroku\bin;G:\Program Files (x86)\Git\bin;G:\Program Files (x86)\composer;G:\Program Files (x86)\nodejs;G:\Program Files (x86)\Sublime Text 3;G:\Program Files (x86)\Microsoft VS Code\bin;G:\Program Files (x86)\cygwin64\bin

list2 = [1, 2, 3, 4, 1, 2, 3]
lset = set()
[(lset.add(item), list2.append(item))
 for item in list2 if item not in lset]
print list(lset)

onSaveInstanceState() for transient data (restored in onCreate()/onRestoreInstanceState()), onPause() for persistent data (restored in onResume()). From Android technical resources:

onSaveInstanceState() is called by Android if the Activity is being stopped and may be killed before it is resumed! This means it should store any state necessary to re-initialize to the same condition when the Activity is restarted. It is the counterpart to the onCreate() method, and in fact the savedInstanceState Bundle passed in to onCreate() is the same Bundle that you construct as outState in the onSaveInstanceState() method.

onPause() and onResume() are also complimentary methods. onPause() is always called when the Activity ends, even if we instigated that (with a finish() call for example). We will use this to save the current note back to the database. Good practice is to release any resources that can be released during an onPause() as well, to take up less resources when in the passive state.

I notice that you mention a function %like% in your current approach. I don't know if that's a reference to the %like% from "data.table", but if it is, you can definitely use it as follows.

Note that the object does not have to be a data.table (but also remember that subsetting approaches for data.frames and data.tables are not identical):

library(data.table)
mtcars[rownames(mtcars) %like% "Merc", ]
iris[iris$Species %like% "osa", ]

If that is what you had, then perhaps you had just mixed up row and column positions for subsetting data.

If you don't want to load a package, you can try using grep() to search for the string you're matching. Here's an example with the mtcars dataset, where we are matching all rows where the row names includes "Merc":

mtcars[grep("Merc", rownames(mtcars)), ]
             mpg cyl  disp  hp drat   wt qsec vs am gear carb
# Merc 240D   24.4   4 146.7  62 3.69 3.19 20.0  1  0    4    2
# Merc 230    22.8   4 140.8  95 3.92 3.15 22.9  1  0    4    2
# Merc 280    19.2   6 167.6 123 3.92 3.44 18.3  1  0    4    4
# Merc 280C   17.8   6 167.6 123 3.92 3.44 18.9  1  0    4    4
# Merc 450SE  16.4   8 275.8 180 3.07 4.07 17.4  0  0    3    3
# Merc 450SL  17.3   8 275.8 180 3.07 3.73 17.6  0  0    3    3
# Merc 450SLC 15.2   8 275.8 180 3.07 3.78 18.0  0  0    3    3

And, another example, using the iris dataset searching for the string osa:

irisSubset <- iris[grep("osa", iris$Species), ]
head(irisSubset)
#   Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1          5.1         3.5          1.4         0.2  setosa
# 2          4.9         3.0          1.4         0.2  setosa
# 3          4.7         3.2          1.3         0.2  setosa
# 4          4.6         3.1          1.5         0.2  setosa
# 5          5.0         3.6          1.4         0.2  setosa
# 6          5.4         3.9          1.7         0.4  setosa

For your problem try:

selectedRows <- conservedData[grep("hsa-", conservedData$miRNA), ]

Another reason why you should avoid converting the column to varchar(max) is because you cannot create an index on a varchar(max) column.

For Android Studio on Mac :

Navigation Bar :

Android Studio > Preferences > Build, Execution, Deployment > Instant Run > Uncheck : Enable Instant Run

For Android Studio on Windows :

File > Settings > Build, Execution, Deployment > Instant Run > Uncheck : Enable Instant Run

You could use PhoneGap.

This has the benefit of being a cross-platform solution. Be warned though that you may need to pay subscription fees. The simplest solution is to just embed a WebView as detailed in @Enigma's answer.

In NetBeans IDE 8.0 you can use a community contributed plugin https://github.com/tusharvjoshi/nbrunwithargs which will allow you to pass arguments while Run Project or Run Single File command.

For passing arguments to Run Project command either you have to set the arguments in the Project properties Run panel, or use the new command available after installing the plugin which says Run with Arguments

For passing command line arguments to a Java file having main method, just right click on the method and choose Run with Arguments command, of this plugin

UPDATE (24 mar 2014) This plugin is now available in NetBeans Plugin Portal that means it can be installed from Plugins dialog box from the available plugins shown from community contributed plugins, in NetBeans IDE 8.0

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

First Thing

  TextEditingController MyController= new TextEditingController();

Then add it to init State or in any SetState

    MyController.value = TextEditingValue(text: "ANY TEXT");

Java's Primitive Data Types

boolean: 1-bit. May take on the values true and false only.

byte: 1 signed byte (two's complement). Covers values from -128 to 127.

short: 2 bytes, signed (two's complement), -32,768 to 32,767

int: 4 bytes, signed (two's complement). -2,147,483,648 to 2,147,483,647.

long: 8 bytes signed (two's complement). Ranges from -9,223,372,036,854,775,808 to +9,223,372,036,854,775,807.

float: 4 bytes, IEEE 754. Covers a range from 1.40129846432481707e-45 to 3.40282346638528860e+38 (positive or negative).

double: 8 bytes IEEE 754. Covers a range from 4.94065645841246544e-324d to 1.79769313486231570e+308d (positive or negative).

char: 2 bytes, unsigned, Unicode, 0 to 65,535

if you have no systemctl and started the docker daemon by:

sudo service docker start

you can stop it by:

sudo service docker stop

If you already know the key, you can directly update the value at that key using m[key] = new_value

Here is a sample code that might help:

map<int, int> m;

for(int i=0; i<5; i++)
    m[i] = i;

for(auto it=m.begin(); it!=m.end(); it++)
    cout<<it->second<<" ";
//Output: 0 1 2 3 4

m[4] = 7;  //updating value at key 4 here

cout<<"\n"; //Change line

for(auto it=m.begin(); it!=m.end(); it++)
    cout<<it->second<<" ";
// Output: 0 1 2 3 7    

If you need avoid floating point problem on rounding numbers for accounting, you can use numpy round.

You need install numpy :

pip install numpy

and the code :

import numpy as np

print(round(2.675, 2))
print(float(np.round(2.675, 2)))

prints

2.67
2.68

You should use that if you manage money with legal rounding.

You can use background-size: cover;

DateTime.UtcNow.ToString("s")

Returns something like 2008-04-10T06:30:00

UtcNow obviously returns a UTC time so there is no harm in:

string.Concat(DateTime.UtcNow.ToString("s"), "Z")

Well, years ago I made the program like you presented here.
There is one hidden problem (or many, depends on point of view):

• If the speed of the ball is too high, you can miss the collision.

And also, almost in 100% cases your new speeds will be wrong. Well, not speeds, but positions. You have to calculate new speeds precisely in the correct place. Otherwise you just shift balls on some small "error" amount, which is available from the previous discrete step.

The solution is obvious: you have to split the timestep so, that first you shift to correct place, then collide, then shift for the rest of the time you have.

To store DataTable in Session:

DataTable dtTest = new DataTable();
Session["dtTest"] = dtTest; 

To retrieve DataTable from Session:

DataTable dt = (DataTable) Session["dtTest"];

To add to Preston's answer, here's the complete list of the HttpContent derived classes available in the standard library:

Credit: https://pfelix.wordpress.com/2012/01/16/the-new-system-net-http-classes-message-content/

There's also a supposed ObjectContent but I was unable to find it in ASP.NET Core.

Of course, you could skip the whole HttpContent thing all together with Microsoft.AspNet.WebApi.Client extensions (you'll have to do an import to get it to work in ASP.NET Core for now: https://github.com/aspnet/Home/issues/1558) and then you can do things like:

var response = await client.PostAsJsonAsync("AddNewArticle", new Article
{
    Title = "New Article Title",
    Body = "New Article Body"
});

We can use the get_locale function:

if (get_locale() == 'en_GB') {
    // drink tea
}

GOINSIDE SOLUTION

install goinside command line tool with:

sudo npm install -g goinside

and go inside a docker container with a proper terminal size with:

goinside docker_container_name

old answer

We've put this snippet in ~/.profile:

goinside(){
    docker exec -it $1 bash -c "stty cols $COLUMNS rows $LINES && bash";
}
export -f goinside

Not only does this make everyone able to get inside a running container with:

goinside containername

It also solves a long lived problem about fixed Docker container terminal sizes. Which is very annoying if you face it.

Also if you follow the link you'll have command completion for your docker container names too.

ERROR 2005 (HY000): Unknown MySQL server host 'localhost' (0)

modify list of host names for your system:

C:\Windows\System32\drivers\etc\hosts

Make sure that you have the following entry:

127.0.0.1 localhost
In my case that entry was 0.0.0.0 localhost which caussed all problem

(you may need to change modify permission to modify this file)

This performs DNS resolution of host “localhost” to the IP address 127.0.0.1.

Register an out parameter for the stored procedure, and set the value based on @@ROWCOUNT if using SQL Server. Use SQL%ROWCOUNT if you are using Oracle.

Mind that if you have multiple INSERT/UPDATE/DELETE, you'll need a variable to store the result from @@ROWCOUNT for each operation.

The .size() method is deprecated as of jQuery 1.8. Use the .length property instead

In my case adding Preamble to file solved my problem:

var data = Encoding.UTF8.GetBytes(csv);
var result = Encoding.UTF8.GetPreamble().Concat(data).ToArray();
return File(new MemoryStream(result), "application/octet-stream", "data.csv");

if you wrote: -Xms512m -Xmx512m when it start, java allocate in those moment 512m of ram for his process and cant increment.

-Xms64m -Xmx512m when it start, java allocate only 64m of ram for his process, but java can be increment his memory occupation while 512m.

I think that second thing is better because you give to java the automatic memory management.
