sprintf is what you need.

EDIT (somehow requested by the downvotes), from the page linked above, here's a sample "zero-padded integers":

<?php
    $isodate = sprintf("%04d-%02d-%02d", $year, $month, $day);
?>

You can still use installutil without visual studio, it is included with the .net framework

On your server, open a command prompt as administrator then:

CD C:\Windows\Microsoft.NET\Framework\v4.0.version (insert your version)

installutil "C:\Program Files\YourWindowsService\YourWindowsService.exe" (insert your service name/location)

To uninstall:

installutil /u "C:\Program Files\YourWindowsService\YourWindowsService.exe" (insert your service name/location)

Angular's $http has a cache built in. According to the docs:

cache – {boolean|Object} – A boolean value or object created with $cacheFactory to enable or disable caching of the HTTP response. See $http Caching for more information.

Boolean value

So you can set cache to true in its options:

$http.get(url, { cache: true}).success(...);

or, if you prefer the config type of call:

$http({ cache: true, url: url, method: 'GET'}).success(...);

Cache Object

You can also use a cache factory:

var cache = $cacheFactory('myCache');

$http.get(url, { cache: cache })

You can implement it yourself using $cacheFactory (especially handly when using $resource):

var cache = $cacheFactory('myCache');

var data = cache.get(someKey);

if (!data) {
   $http.get(url).success(function(result) {
      data = result;
      cache.put(someKey, data);
   });
}

[string[]]$recipients = $address.Split('; ',[System.StringSplitOptions]::RemoveEmptyEntries)

I was having serious problems with

.data('property', value);

It was not setting the data-property attribute.

Started using jQuery's .attr():

Get the value of an attribute for the first element in the set of matched elements or set one or more attributes for every matched element.

.attr('property', value)

to set the value and

.attr('property')

to retrieve the value.

Now it just works!

You have to use .onload

let canvas = document.getElementById("myCanvas");
let ctx = canvas.getContext("2d"); 

const drawImage = (url) => {
    const image = new Image();
    image.src = url;
    image.onload = () => {
       ctx.drawImage(image, 0, 0)
    }
}

Here's Why

If you are loading the image first after the canvas has already been created then the canvas won't be able to pass all the image data to draw the image. So you need to first load all the data that came with the image and then you can use drawImage()

my simple solution, pretty and easy to understand.

array_reverse($array)[0];

This task can be accomplished without blueprints and tricky imports using Centralized URL Map

app.py

import views
from flask import Flask

app = Flask(__name__)

app.add_url_rule('/', view_func=views.index)
app.add_url_rule('/other', view_func=views.other)

if __name__ == '__main__':
    app.run(debug=True, use_reloader=True)

views.py

from flask import render_template

def index():
    return render_template('index.html')

def other():
    return render_template('other.html')

In Web-"MVC" you can do whatever you please.

The original concept ⁽¹⁾ described the model as the business logic. It should represent the application state and enforce some data consistency. That approach is often described as "fat model".

Most PHP frameworks follow a more shallow approach, where the model is just a database interface. But at the very least these models should still validate the incoming data and relations.

Either way, you're not very far off if you separate the SQL stuff or database calls into another layer. This way you only need to concern yourself with the real data/behaviour, not with the actual storage API. (It's however unreasonable to overdo it. You'll e.g. never be able to replace a database backend with a filestorage if that wasn't designed ahead.)

There was conflict in java version. Resolved after using 1.8 for maven.

iOs 10+ allow video autoplay inline. but you have to turn off "Low power mode" on your iPhone.

As it appears, Graphviz2.37 is known to have problems with the PATH variable on windows. I uninstalled it, removed the environment variables associated with it and instead downloaded and installed the newer beta version 2.39 and it now works like a charm.

Don't use spaces...

(Incorrect)

SPTH = '/home/Foo/Documents/Programs/ShellScripts/Butler'

(Correct)

SPTH='/home/Foo/Documents/Programs/ShellScripts/Butler'

Or git stash (if you have changes) on the branch you're on, checkout master, pull for the latest changes, grab that file to your desktop (or the entire app). Checkout the branch you were on. Git stash apply back to the state you were at, then fix the changes manually or drag it replacing the file.

This way is not sooooo cool but it def works if you guys can't figure anything else out.

Doing a relative import is absolulutely OK! Here's what little 'ol me does:

#first change the cwd to the script path
scriptPath = os.path.realpath(os.path.dirname(sys.argv[0]))
os.chdir(scriptPath)

#append the relative location you want to import from
sys.path.append("../common")

#import your module stored in '../common'
import common.py

I think you'll want to look at the <intent-filter> element of your Mainfest file. Specifically, take a look at the documentation for the <data> sub-element.

Basically, what you'll need to do is define your own scheme. Something along the lines of:

<intent-filter>
    <data android:scheme="anton" />
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" /> <--Not positive if this one is needed
    ...
</intent-filter>

Then you should be able to launch your app with links that begin with the anton: URI scheme.

DATETIME2 has a date range of "0001 / 01 / 01" through "9999 / 12 / 31" while the DATETIME type only supports year 1753-9999.

Also, if you need to, DATETIME2 can be more precise in terms of time; DATETIME is limited to 3 1/3 milliseconds, while DATETIME2 can be accurate down to 100ns.

Both types map to System.DateTime in .NET - no difference there.

If you have the choice, I would recommend using DATETIME2 whenever possible. I don't see any benefits using DATETIME (except for backward compatibility) - you'll have less trouble (with dates being out of range and hassle like that).

Plus: if you only need the date (without time part), use DATE - it's just as good as DATETIME2 and saves you space, too! :-) Same goes for time only - use TIME. That's what these types are there for!

Delete everything from this file.

C:\wamp\bin\mysql\mysql5.1.36\data\mysql-bin.index

Restart mysql server and it should work.

Something to note here. We had the same issue with Windows VM's running on an ESXi host. The time sync was turned on in VMWare Tools on the guest, but the guest clocks were consistently off (by about 30 seconds) from the host clock. The ESXi host was configured to get time updates from an internal time server.

It turns out we had the Internet Time setting turned on in the Windows VM's (Control Panel > Date and Time > Internet Time tab) so the guest was getting time updates from two places and the internet time was winning. We turned that off and now the guest clocks are good, getting their time exclusively from the ESXi host.

If your input string could be less than five characters long then you should be aware that string.Substring will throw an ArgumentOutOfRangeException if the startIndex argument is negative.

To solve this potential problem you can use the following code:

string sub = input.Substring(Math.Max(0, input.Length - 5));

Or more explicitly:

public static string Right(string input, int length)
{
    if (length >= input.Length)
    {
        return input;
    }
    else
    {
        return input.Substring(input.Length - length);
    }
}

If your click handler is successfully called then this should work:

$('#results').on('click', '.item', function () {
            var NestId = $(this).data('id');
            var url = "/Artists/Details?NestId=" + NestId; 
            window.location.href = url; 
        })

EDIT: In this particular case given that the action method parameter is a string which is nullable, then if NestId == null, won't cause any exception at all, given that the ModelBinder won't complain about it.

It's better to check the version of python where you want to install your package. If the wheel was built for python3 and your python version is python2.x you may get this error. While installing using pip follow this convention

python2 -m pip install XXXXXX.whl #if .whl is for python2
python3 -m pip install XXXXXX.whl #if .whl is for python3

I think what you want might be to run the following from the command line:

ipython notebook --matplotlib=inline

If you don't like typing it at the cmd line every time then you could create an alias to do it for you.

You can also do it "the joiner way" by inserting "U+2060 Word Joiner".

If Accept-Charset permits, the unicode character itself can be inserted directly into the HTML output.

Otherwise, it can be done using entity encoding. E.g. to join the text red-brown, use:

red-⁠brown

or (decimal equivalent):

red-⁠brown

. Another usable character is "U+FEFF Zero Width No-break Space"^{[⁠ ⁠1 ]}:

red-brown

and (decimal equivalent):

red-brown

^{[1]: Note that while this method still works in major browsers like Chrome, it has been deprecated since Unicode 3.2.}

Comparison of "the joiner way" with "U+2011 Non-breaking Hyphen":

• The word joiner can be used for all other characters, not just hyphens.

• When using the word joiner, most renderers will rasterize the text identically. On Chrome, FireFox, IE, and Opera, the rendering of normal hyphens, eg:

  a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r-s-t-u-v-w-x-y-z

  is identical to the rendering of normal hyphens (with U+2060 Word Joiner), eg:

  a-⁠b-⁠c-⁠d-⁠e-⁠f-⁠g-⁠h-⁠i-⁠j-⁠k-⁠l-⁠m-⁠n-⁠o-⁠p-⁠q-⁠r-⁠s-⁠t-⁠u-⁠v-⁠w-⁠x-⁠y-⁠z

  while the above two renders differ from the rendering of "Non-breaking Hyphen", eg:

  a‑b‑c‑d‑e‑f‑g‑h‑i‑j‑k‑l‑m‑n‑o‑p‑q‑r‑s‑t‑u‑v‑w‑x‑y‑z

  . (The extent of the difference is browser-dependent and font-dependent. E.g. when using a font declaration of "arial", Firefox and IE11 show relatively huge variations, while Chrome and Opera show smaller variations.)

Comparison of "the joiner way" with <span class=c1></span> (CSS .c1 {white-space:nowrap;}) and <nobr></nobr>:

• The word joiner can be used for situations where usage of HTML tags is restricted, e.g. forms of websites and forums.

• On the spectrum of presentation and content, majority will consider the word joiner to be closer to content, when compared to tags.

^{• As tested on Windows 8.1 Core 64-bit using:
    • IE 11.0.9600.18205
    • Firefox 43.0.4
    • Chrome 48.0.2564.109 (Official Build) m (32-bit)
    • Opera 35.0.2066.92}

This should work, but there is a little trick. After you enter the formula, you need to hold down Ctrl+Shift while you press Enter. When you do, you'll see that the formula bar has curly-braces around your formula. This is called an array formula.

For example, if the Months are in cells A2:A100 and the amounts are in cells B2:B100, your formula would look like {=SUM(If(A2:A100="January",B2:B100))}. You don't actually type the curly-braces though.

You could also do something like =SUM((A2:A100="January")*B2:B100). You'd still need to use the trick to get it to work correctly.

One option is to put the subquery in a LEFT JOIN:

select sum ( t.graduates ) - t1.summedGraduates 
from table as t
    left join 
     ( 
        select sum ( graduates ) summedGraduates, id
        from table  
        where group_code not in ('total', 'others' )
        group by id 
    ) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates 

Perhaps a better option would be to use SUM with CASE:

select sum(case when group_code = 'total' then graduates end) -
    sum(case when group_code not in ('total','others') then graduates end)
from yourtable

Change display:inline to display:inline-block

.test {
  width:200px;
  display:inline-block;
  overflow: auto;
  white-space: nowrap;
  margin:0px auto;
  border:1px red solid;
}

You can pass $ in function()

jQuery(document).ready(function($){

// jQuery code is in here

});

or you can replace $(document); with this jQuery(document);

or you can use jQuery.noConflict()

var jq=jQuery.noConflict();
jq(document).ready(function(){  
  jq('selector').show();
});

You can return empty array by following two ways:

If you want to return array of int then

1. Using {}:

   int arr[] = {};
   return arr;
   

2. Using new int[0]:

   int arr[] = new int[0];
   return arr;
   

Same way you can return array for other datatypes as well.

It's not that different in bash.

workdone=0
while : ; do
  ...
  if [ "$workdone" -ne 0 ]; then
      break
  fi
done

: is the no-op command; its exit status is always 0, so the loop runs until workdone is given a non-zero value.

There are many ways you could set and test the value of workdone in order to exit the loop; the one I show above should work in any POSIX-compatible shell.

Try making your changes in:

- (void) viewWillLayoutSubviews {}

The code will run at every orientation change as the subviews get laid out again.

You can do as:

import pandas as pd
df = pd.read_csv('file_location\filename.txt', delimiter = "\t")

(like, df = pd.read_csv('F:\Desktop\ds\text.txt', delimiter = "\t")

Since it appears you are using jQuery, here is a jQuery solution.

$(function() {
    $('#Eframe').on("mousewheel", function() {
        alert($(document).scrollTop());
    });
});

Not much to explain here. If you want, here is the jQuery documentation.

This does the trick. I only test it in Django 1.7.

your_fields = YourModel._meta.local_fields
your_field_names = [f.name for f in your_fields]

Model._meta.local_fields does not contain many-to-many fields. You should get them using Model._meta.local_many_to_many.

The current directory is a system-level feature; it returns the directory that the server was launched from. It has nothing to do with the website.

You want HttpRuntime.AppDomainAppPath.

If you're in an HTTP request, you can also call Server.MapPath("~/Whatever").

I would say that you should put styles that won't change into a regular style attribute, and conditional/scope styles into an ng-style attribute. Also, string keys are not necessary. For hyphen-delimited CSS keys, use camelcase.

<div ng-style="{backgroundColor: data.backgroundCol}" style="width:20px; height:20px; margin-top:10px; border:solid 1px black;"></div>

$mystring = "this is the text I would like to truncate";

// Pass your variable to the function
$mystring = truncate($mystring);

// Truncated tring printed out;
echo $mystring;

//truncate text function
public function truncate($text) {

    //specify number fo characters to shorten by
    $chars = 25;

    $text = $text." ";
    $text = substr($text,0,$chars);
    $text = substr($text,0,strrpos($text,' '));
    $text = $text."...";
    return $text;
}

Alternatively, this solution works with both Apache2 version < 2.4 as well as >= 2.4. Make sure that the "version" module is enabled:

a2enmod version

And then use this code instead:

<IfVersion < 2.4>
    Allow from all
</IfVersion>
<IfVersion >= 2.4>
    Require all granted
</IfVersion>

string Value = dic.ContainsKey("Name") ? dic["Name"] : "Required Name"

With this code, we will get string data in 'Value'. If key 'Name' exists in the dictionary 'dic' then fetch this value, else returns "Required Name" string.

Use a service api.

URL: https://fcm.googleapis.com/fcm/send

Method Type: POST

Headers:

Content-Type: application/json
Authorization: key=your api key

Body/Payload:

{ "notification": {
    "title": "Your Title",
    "text": "Your Text",
     "click_action": "OPEN_ACTIVITY_1" // should match to your intent filter
  },
    "data": {
    "keyname": "any value " //you can get this data as extras in your activity and this data is optional
    },
  "to" : "to_id(firebase refreshedToken)"
} 

And with this in your app you can add below code in your activity to be called:

<intent-filter>
    <action android:name="OPEN_ACTIVITY_1" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

PHP will let you build the pages of your site that make up your video conferencing and chat applications, but it won't deliver or stream video for you - PHP runs on the server only and renders out HTML to a client browser.

For the video, the first thing you'll need is a live streaming account with someone like akamai or the numerous others in the field. Using this account gives you an ingress point for your video - ie: the server that you will stream your live video up to.

Next, you want to get your video out to the browsers - windows media player, flash or silverlight will let you achieve this - embedding the appropriate control for your chosen technology into your page (using PHP or whatever) and given the address of your live video feed.

PHP (or other scripting language) would be used to build the chat part of the application and bring the whole thing together (the chat and the embedded video player).

Hope this helps.

This issue can be caused by the libxml entity loader having been disabled.

Try running libxml_disable_entity_loader(false); before instantiating SoapClient.

According to this, you will need .NET 4.5 installed. For more details, visit the webpage. The gist of it is that after you have .NET 4.5 installed, your 4.0 apps will use the 4.5 System.dll. You can enable TLS 1.2 in two ways:

• At the beginning of the application, add this code: ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;
• Set the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319: SchUseStrongCrypto to DWORD 1

From the RFC (3023), under section 3, XML Media Types:

If an XML document -- that is, the unprocessed, source XML document -- is readable by casual users, text/xml is preferable to application/xml. MIME user agents (and web user agents) that do not have explicit support for text/xml will treat it as text/plain, for example, by displaying the XML MIME entity as plain text. Application/xml is preferable when the XML MIME entity is unreadable by casual users.

Had the same exact error on WinXP box with latest build of my .NET 4 code. Checked previous builds - now they crash too! Ok, so it's not me :). No suggestions here/above helped.

Much more recent (2018-05-09) report of the same problem: Application Crash with exit code 80131506.

A: We were receiving a similar error, but we believe ours was caused by the Citrix memory optimizer.
The resolution was to force a regeneration of the .Net core libraries on the host(s) where the issue was occurring:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ngen.exe update /force

Root cause is still unknown (machine is not being updated and has little use), but that did it for me!

I don't believe so. Even if I'm wrong, the best you can hope for is adding them to an entire Type, never an instance of a Type.

Please take a look at this example here. It is a simple example of a count up! Which I think you could easily modify to create a count down.

if getting from form you need to use POST method cause your form has method="post"

Output :

Laravel Collection implements the PHP ArrayAccess interface (which is why using foreach is possible in the first place).

If you have the key already you can just use PHP unset.

I prefer this, because it clearly modifies the collection in place, and is easy to remember.

foreach ($collection as $key => $value) {
    unset($collection[$key]);
}

Interesting enough, this error also occurs, at time of opening when the .XLS? file is incorrectly formed or require repairs.

A hard to find error is to many rows on a .xls (old excel) file.

Test it: manually open the affected file with excel desktop .

I use automation to process a few hundred files daily, when this error show up, I notify the owner via mail and save the unprocessed file on a temporary location.

No. The heap is cleared by the garbage collector whenever it feels like it. You can ask it to run (with System.gc()) but it is not guaranteed to run.

First try increasing the memory by setting -Xmx256m

This shows how require() works in its simplest form, excerpted from Eloquent JavaScript

Problem It is not possible for a module to directly export a value other than the exports object, such as a function. For example, a module might want to export only the constructor of the object type it defines. Right now, it cannot do that because require always uses the exports object it creates as the exported value.

Solution Provide modules with another variable, module, which is an object that has a property exports. This property initially points at the empty object created by require but can be overwritten with another value in order to export something else.

function require(name) {
  if (name in require.cache)
    return require.cache[name];
  var code = new Function("exports, module", readFile(name));
  var exports = {}, module = {exports: exports};
  code(exports, module);
  require.cache[name] = module.exports;
  return module.exports;
}
require.cache = Object.create(null);

If you are using structured data, this has the added benefit of not invoking an extra shell process to run tr and/or cut or something. ...

(Of course, you will want to guard against bad inputs with conditionals and sane alternatives.)

...
while read line ; 
do 
    lineCols=( $line ) ;
    echo "${lineCols[0]}"
    echo "${lineCols[1]}"
done < $myFQFileToRead ; 
...

Also you can add <br> instead of \n.

And then you can add text to TexView:

articleTextView.setText(Html.fromHtml(textForTextView));

If your email address is '[email protected]', try changing the createDirectoryEntry() as below.

XYZ is an optional parameter if it exists in mydomain directory

static DirectoryEntry createDirectoryEntry()
{
    // create and return new LDAP connection with desired settings
    DirectoryEntry ldapConnection = new DirectoryEntry("myname.mydomain.com");
    ldapConnection.Path = "LDAP://OU=Users, OU=XYZ,DC=mydomain,DC=com";
    ldapConnection.AuthenticationType = AuthenticationTypes.Secure;
    return ldapConnection;
}

This will basically check for com -> mydomain -> XYZ -> Users -> abcd

The main function looks as below:

try
{
    username = "Firstname LastName"
    DirectoryEntry myLdapConnection = createDirectoryEntry();
    DirectorySearcher search = new DirectorySearcher(myLdapConnection);
    search.Filter = "(cn=" + username + ")";
    ....    

You can use the "auto" value for the left and right margins to let the browser distribute the available space equally at both sides of the inner div:

<div id='parent' style='width: 100%;'>
   <div id='child' style='width: 50px; height: 100px; margin-left: auto; margin-right: auto'>Text</div>
</div>

I got a similar error and it took me a while to realize that in my case I named the array variable payInvoices and the function also payInvoices. It confused AngularJs. Once I changed the name to processPayments() it finally worked. Just wanted to share this error and solution as it took me long time to figure this out.

recently i've created this code for my client, i'm using array for cookie in this code, actually this code gets recently viewed pages by user using cookies, hope it helps you...!

function curPageURL() { // get url
return 'http' . ((
!empty($_SERVER['HTTPS']) &&
$_SERVER['HTTPS'] !== 'off' ||
$_SERVER['SERVER_PORT'] == 443
) ? 's' : '') . '://' . $_SERVER['SERVER_NAME'] . (
$_SERVER['SERVER_PORT'] == 80 ? '' :  $_SERVER['SERVER_PORT']
) . $_SERVER['REQUEST_URI'];
}

$currentPage = curPageURL(); // call function
$counter = $_COOKIE['_counter']; // set counter variable

if(!$_COOKIE['_PAGES']){ // if _Pages cookie
$default = 1; // set default value to 1
setcookie("_counter",$default,time()+7200); // set counter cookie
setcookie("_PAGES[$default]",$currentPage, time()+3600); // set cookie  
}
else{ // if ! _Pages cookie 
$default = $counter+1; // set default value to +1
setcookie("_counter",$default,time()+7200); // set counter cookie
}


if(@in_array($currentPage, @$_COOKIE['_PAGES'])){ // if same url found
}
else{ // if new url found
setcookie("_PAGES[$default]",$currentPage, time()+3600); // set cookie  
}


if($_COOKIE['_PAGES']){
foreach ($_COOKIE['_PAGES'] as $value){
    echo "<a href='{$value}'>{$value}</a>";
} 
}

I believe this is what you're looking for:

Convert Decimal Numbers to Text showing only the non-zero decimals

Especially this line might be helpful:

StringVar text     :=  Totext ( {Your.NumberField} , 6 , ""  )  ;

The first parameter is the decimal to be converted, the second parameter is the number of decimal places and the third parameter is the separator for thousands/millions etc.

The reason to use it is because strcmp

returns < 0 if str1 is less than str2; > 0 if str1 is greater than str2, and 0 if they are equal.

=== only returns true or false, it doesn't tell you which is the "greater" string.

Make #container to display:inline-block

#container {

  display: inline-block;
}

#content {
  height: auto;

  margin-left: auto;

You could try a formatter like this

They will always be limited because they don't (and can't) know what user defined functions you may have defined in your database (or which built-in functions you have or don't have access to).

You could also look at ANTLR (but that would be an offline solution)

For the most part, the number of bytes and range of values is determined by the CPU's architecture not by C++. However, C++ sets minimum requirements, which litb explained properly and Martin York only made a few mistakes with.

The reason why you can't use int and long interchangeably is because they aren't always the same length. C was invented on a PDP-11 where a byte had 8 bits, int was two bytes and could be handled directly by hardware instructions. Since C programmers often needed four-byte arithmetic, long was invented and it was four bytes, handled by library functions. Other machines had different specifications. The C standard imposed some minimum requirements.

There is now an extension method to convert the IEnumerable<> to a Dictionary<,> which then has a Remove method.

public readonly IEnumerable<User> Users = new User[]; // or however this would be initialized

// To take an item out of the collection
Users.ToDictionary(u => u.Id).Remove(1123);

// To take add an item to the collection
Users.ToList().Add(newuser);

This Jquery method returns the default vale 0 when page loads...

$('input[type="radio"]:checked').val();

Use the extern keyword to declare the variable in the other .c file. E.g.:

extern int counter;

means that the actual storage is located in another file. It can be used for both variables and function prototypes.

If you are working in Ubuntu,follow the steps:

1. Press / and type word to search
2. To search in forward press 'SHIFT' key with * key
3. To search in backward press 'SHIFT' key with # key

In my case other solutions did not work than this way:

$('.bootstrap-filestyle :input').val('');

However, if you will have more than 1 file input on page, it will reset the text on all of them.

AllDogs.First(d => d.Id == "2").Name = "some value";

However, a safer version of that might be this:

var dog = AllDogs.FirstOrDefault(d => d.Id == "2");
if (dog != null) { dog.Name = "some value"; }

Realize this is an old question, but with the newer version of JQuery you can now do the following:

$("option[val=ID]").prop("selected",true);

This accomplishes the same thing as Box9's selected answer in one line.

$datetime = DateTime::createFromFormat('Ymd', '20151102');

echo $datetime->format('D');

The 2 domains mydomain.com and subdomain.mydomain.com can only share cookies if the domain is explicitly named in the Set-Cookie header. Otherwise, the scope of the cookie is restricted to the request host. (This is referred to as a "host-only cookie". See What is a host only cookie?)

For instance, if you sent the following header from subdomain.mydomain.com, then the cookie won't be sent for requests to mydomain.com:

Set-Cookie: name=value

However if you use the following, it will be usable on both domains:

Set-Cookie: name=value; domain=mydomain.com

This cookie will be sent for any subdomain of mydomain.com, including nested subdomains like subsub.subdomain.mydomain.com.

In RFC 2109, a domain without a leading dot meant that it could not be used on subdomains, and only a leading dot (.mydomain.com) would allow it to be used across multiple subdomains (but not the top-level domain, so what you ask was not possible in the older spec).

However, all modern browsers respect the newer specification RFC 6265, and will ignore any leading dot, meaning you can use the cookie on subdomains as well as the top-level domain.

In summary, if you set a cookie like the second example above from mydomain.com, it would be accessible by subdomain.mydomain.com, and vice versa. This can also be used to allow sub1.mydomain.com and sub2.mydomain.com to share cookies.

I whould choose swing just because it's "native" for java.

Plus, have a look at http://swingx.java.net/.

I know this is an old question, but I stumbled upon the same problem and tried to use the function given in Alex's answer.

But the quality in the jpeg result was too low. So I changed the function a little bit to become more usable in my project and changed the "imagecopyresized" to "imagecopyresampled" (according to this recomendation).

If you are having questions about how to use this function, then try taking a look at the well documented version here.

function createThumbnail($filepath, $thumbpath, $thumbnail_width, $thumbnail_height, $background=false) {
    list($original_width, $original_height, $original_type) = getimagesize($filepath);
    if ($original_width > $original_height) {
        $new_width = $thumbnail_width;
        $new_height = intval($original_height * $new_width / $original_width);
    } else {
        $new_height = $thumbnail_height;
        $new_width = intval($original_width * $new_height / $original_height);
    }
    $dest_x = intval(($thumbnail_width - $new_width) / 2);
    $dest_y = intval(($thumbnail_height - $new_height) / 2);

    if ($original_type === 1) {
        $imgt = "ImageGIF";
        $imgcreatefrom = "ImageCreateFromGIF";
    } else if ($original_type === 2) {
        $imgt = "ImageJPEG";
        $imgcreatefrom = "ImageCreateFromJPEG";
    } else if ($original_type === 3) {
        $imgt = "ImagePNG";
        $imgcreatefrom = "ImageCreateFromPNG";
    } else {
        return false;
    }

    $old_image = $imgcreatefrom($filepath);
    $new_image = imagecreatetruecolor($thumbnail_width, $thumbnail_height); // creates new image, but with a black background

    // figuring out the color for the background
    if(is_array($background) && count($background) === 3) {
      list($red, $green, $blue) = $background;
      $color = imagecolorallocate($new_image, $red, $green, $blue);
      imagefill($new_image, 0, 0, $color);
    // apply transparent background only if is a png image
    } else if($background === 'transparent' && $original_type === 3) {
      imagesavealpha($new_image, TRUE);
      $color = imagecolorallocatealpha($new_image, 0, 0, 0, 127);
      imagefill($new_image, 0, 0, $color);
    }

    imagecopyresampled($new_image, $old_image, $dest_x, $dest_y, 0, 0, $new_width, $new_height, $original_width, $original_height);
    $imgt($new_image, $thumbpath);
    return file_exists($thumbpath);
}

The default location for logon scripts is the netlogon share of a domain controller. On the server this is located:

%SystemRoot%'SYSVOL'sysvol''scripts

It can presumably be changes from this default but I've never met anyone that had a reason to.

To get list of domain controllers programatically see this article: http://www.microsoft.com/technet/scriptcenter/resources/qanda/dec04/hey1216.mspx

It might be cleaner to take out your inline click handler and do it like this:

$(document).ready(function() {
    $('#button-id').click(function() {
      foo($('#formValueId').val());
    });
});

Use a CompletableFuture in Java 8

    // Kick of multiple, asynchronous lookups
    CompletableFuture<User> page1 = gitHubLookupService.findUser("Test1");
    CompletableFuture<User> page2 = gitHubLookupService.findUser("Test2");
    CompletableFuture<User> page3 = gitHubLookupService.findUser("Test3");

    // Wait until they are all done
    CompletableFuture.allOf(page1,page2,page3).join();

    logger.info("--> " + page1.get());

this is pretty simple:

HttpUtility.HtmlDecode(Model.Content)

Another Solution, you could also return a HTMLString, Razor will output the correct formatting:

in the view itself:

@Html.GetSomeHtml()

in controller:

public static HtmlString GetSomeHtml()
{
    var Data = "abc<br/>123";
    return new HtmlString(Data);
}

Create a list of lists:

with open("/path/to/file") as file:
    lines = []
    for line in file:
        # The rstrip method gets rid of the "\n" at the end of each line
        lines.append(line.rstrip().split(","))

"error: unmappable character for encoding UTF-8" means, java has found a character which is not representing in UTF-8. Hence open the file in an editor and set the character encoding to UTF-8. You should be able to find a character which is not represented in UTF-8.Take off this character and recompile.

I also faced this problem and fixed it by removing version part from the XSD name.

http://www.springframework.org/schema/beans/spring-beans-4.2.xsd to http://www.springframework.org/schema/beans/spring-beans.xsd

Versions less XSD's are mapped to the current version of the framework used in the application.

Do this

...
var el = document.getElementById('targetFrame');

var frame_win = getIframeWindow(el);

console.log(frame_win);
...

getIframeWindow is defined here

function getIframeWindow(iframe_object) {
  var doc;

  if (iframe_object.contentWindow) {
    return iframe_object.contentWindow;
  }

  if (iframe_object.window) {
    return iframe_object.window;
  } 

  if (!doc && iframe_object.contentDocument) {
    doc = iframe_object.contentDocument;
  } 

  if (!doc && iframe_object.document) {
    doc = iframe_object.document;
  }

  if (doc && doc.defaultView) {
   return doc.defaultView;
  }

  if (doc && doc.parentWindow) {
    return doc.parentWindow;
  }

  return undefined;
}

If it is just avoiding the exception you are worried about, the "find_all_by.." family of functions works without throwing exceptions.

Comment.find_all_by_id([2, 3, 5])

will work even if some of the ids don't exist. This works in the

user.comments.find_all_by_id(potentially_nonexistent_ids)

case as well.

Update: Rails 4

Comment.where(id: [2, 3, 5])

If you use auto-layout on iOS 6 you might also need to set the preferredMaxLayoutWidth property:

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
button.titleLabel.textAlignment = NSTextAlignmentCenter;
button.titleLabel.preferredMaxLayoutWidth = button.frame.size.width;

It may be two years too late, but I ran into the same problem recently and this is the solution I ended up with after finding this post:

import javax.tools.ToolProvider

dependencies {
  compile (
    files(((URLClassLoader) ToolProvider.getSystemToolClassLoader()).getURLs()),
    ...
  }
}

It should work if java.home points to a directory that's not under the JDK directory and even on Mac OS where you'd have classes.jar instead of tools.jar.

you need to replace "/" with "7", it works on non english keyboard layout.

based on other solutions, you generate accumulative distribution (as integer or float whatever you like), then you can use bisect to make it fast

this is a simple example (I used integers here)

l=[(20, 'foo'), (60, 'banana'), (10, 'monkey'), (10, 'monkey2')]
def get_cdf(l):
    ret=[]
    c=0
    for i in l: c+=i[0]; ret.append((c, i[1]))
    return ret

def get_random_item(cdf):
    return cdf[bisect.bisect_left(cdf, (random.randint(0, cdf[-1][0]),))][1]

cdf=get_cdf(l)
for i in range(100): print get_random_item(cdf),

the get_cdf function would convert it from 20, 60, 10, 10 into 20, 20+60, 20+60+10, 20+60+10+10

now we pick a random number up to 20+60+10+10 using random.randint then we use bisect to get the actual value in a fast way

according to the composer reference there are two relevant options: disable-tls and secure-http.

nano ~/.composer/config.json (If the file does not exist or is empty, then just create it with the following content)

{
    "config": {
        "disable-tls": true,
        "secure-http": false
    }
}

then it complains much:

You are running Composer with SSL/TLS protection disabled.
Warning: Accessing getcomposer.org over http which is an insecure protocol.

but it performs the composer selfupdate (or whatever).

while one cannot simply "enable SSL in the php.ini" on Linux; PHP needs to be compiled with openSSL configured as shared library - in order to be able to access it from the PHP CLI SAPI.

What about

Game.status[0][0] or Game.status[0]["0"] ?

Does one of these work?

PS: What you have in your question is a Javascript Object, not JSON. JSON is the 'string' version of a Javascript Object.

JsonLint is good for validating and formatting JSON.

You're overcomplicating things:

var e = $('<div style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');
e.attr('id', 'myid');
$('#box').append(e);

For example: http://jsfiddle.net/ambiguous/Dm5J2/

I don't know how stubhub's api works, but generally it should look like this:

s = requests.Session()
data = {"login":"my_login", "password":"my_password"}
url = "http://example.net/login"
r = s.post(url, data=data)

Now your session contains cookies provided by login form. To access cookies of this session simply use

s.cookies

Any further actions like another requests will have this cookie

This form, slightly changed from Kevin Ogoros's one:

na_count <-function (x) sapply(x, function(y) sum(is.na(y)))

returns NA counts as named int array

I ended up rolling my own StaticServlet. It supports If-Modified-Since, gzip encoding and it should be able to serve static files from war-files as well. It is not very difficult code, but it is not entirely trivial either.

The code is available: StaticServlet.java. Feel free to comment.

Update: Khurram asks about the ServletUtils class which is referenced in StaticServlet. It is simply a class with auxiliary methods that I used for my project. The only method you need is coalesce (which is identical to the SQL function COALESCE). This is the code:

public static <T> T coalesce(T...ts) {
    for(T t: ts)
        if(t != null)
            return t;
    return null;
}

Yes, this is an old question. But it's misleading, as this was the first result in my search, and both the answers aren't correct anymore.

You can change your Github account name at any time.

To do this, click your profile picture > Settings > Account Settings > Change Username.

Links to your repositories will redirect to the new URLs, but they should be updated on other sites because someone who chooses your abandoned username can override the links. Links to your profile page will be 404'd.

For more information, see the official help page.

And furthermore, if you want to change your username to something else, but that specific username is being taken up by someone else who has been completely inactive for the entire time their account has existed, you can report their account for name squatting.

found this and it worked for me.

strSQL = "SELECT * FROM DataTable" 

'Where DataTable is the Named range

How can I run SQL statements on a named range within an excel sheet?

You're using curvy-braces when you should be using parentheses.

A where statement is kept inside a scriptblock, which is defined using curvy baces { }. To isolate/wrap you tests, you should use parentheses ().

I would also suggest trying to do the filtering on the remote computer. Try:

Invoke-Command -computername SERVERNAME {
    Get-ChildItem -path E:\dfsroots\datastore2\public |
    Where-Object { ($_.extension -eq "xls" -or $_.extension -eq "xlk") -and $_.creationtime -ge "06/01/2014" }
}

A good solution for me was to simply not using the outdated user cache any more after deploy.

If you add prefix to each of you keys you can change the prefix on changing the data structure of cache entries. This will help you to get the following behavior on deploy:

1. Don't use outdated cache entries after deploy of only updated structures
2. Don't clean the whole cache on deploy to not slow down your page
3. Some old cached entries can be reused after reverting your deploy (If the entries wasn't automatically removed already)
4. APC will remove old cache entries after expire OR on missing cache space

This is possible for user cache only.

In CMD, write:

javac -Xlint:unchecked MyGui2.java

it will display the list of unchecked or unsafe operations.

Use ElasticDump

1) yum install epel-release

2) yum install nodejs

3) yum install npm

4) npm install elasticdump

5) cd node_modules/elasticdump/bin

6)

./elasticdump \

  --input=http://192.168.1.1:9200/original \

  --output=http://192.168.1.2:9200/newCopy \

  --type=data

To increase the phpMyAdmin Session Timeout, open config.inc.php in the root phpMyAdmin directory and add this setting (anywhere).

$cfg['LoginCookieValidity'] = <your_new_timeout>;

Where <your_new_timeout> is some number larger than 1800.

Note:

Always keep on mind that a short cookie lifetime is all well and good for the development server. So do not do this on your production server.

One way is to call A's constructor and pass self as an argument, like so:

class B(A):
    def __init__(self):
        A.__init__(self)
        print "hello"

The advantage of this style is that it's very clear. It call A's initialiser. The downside is that it doesn't handle diamond-shaped inheritance very well, since you may end up calling the shared base class's initialiser twice.

Another way is to use super(), as others have shown. For single-inheritance, it does basically the same thing as letting you call the parent's initialiser.

However, super() is quite a bit more complicated under-the-hood and can sometimes be counter-intuitive in multiple inheritance situations. On the plus side, super() can be used to handle diamond-shaped inheritance. If you want to know the nitty-gritty of what super() does, the best explanation I've found for how super() works is here (though I'm not necessarily endorsing that article's opinions).

You did not add # before id of the button. You do not have right selector in your jquery code. So jquery is never execute in your button click. its submitted your form directly not passing any ajax request.

See documentation: http://api.jquery.com/category/selectors/
its your friend.

Try this:

It seems that id: $("#Shareitem").val() is wrong if you want to pass the value of

<input type="hidden" name="id" value="" id="id">

you need to change this line:

id: $("#Shareitem").val()

by

id: $("#id").val()

All together:

 <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
    <script>
    $(document).ready(function(){
      $("#Shareitem").click(function(e){
          e.preventDefault();
        $.ajax({type: "POST",
                url: "/imball-reagens/public/shareitem",
                data: { id: $("#Shareitem").val(), access_token: $("#access_token").val() },
                success:function(result){
          $("#sharelink").html(result);
        }});
      });

SELECT *
FROM table
WHERE MONTH(columnName) = MONTH(CURRENT_DATE())
AND YEAR(columnName) = YEAR(CURRENT_DATE())

You can use git log to display the diffs while searching:

git log -p -- path/to/file

The simplest solution might be to install Java 8 in parallel to Java 9 (if not still still existant) and specify the JVM to be used explicitly in eclipse.ini. You can find a description of this setting including a description how to find eclipse.ini on a Mac at Eclipsepedia

For Debian distributions. Nothing worked for until I added the debian main repositories on the apt sources (I don't know how were they removed): sudo vi /etc/apt/sources.list

and added

deb  http://deb.debian.org/debian  stretch main
deb-src  http://deb.debian.org/debian  stretch main

after that sudo apt-get update (you can upgrade too) and finally sudo apt-get install php-sqlite3

If you just want to do a literal replace in java, use Pattern.quote(string) to escape any string to a literal.

myString.replaceAll(Pattern.quote(matchingStr), replacementStr)

Below script works fine in all browser:

function RadionButtonSelectedValueSet(name, SelectdValue) {
     $('input[name="' + name + '"][value="' + SelectdValue + '"]').attr('checked',true);
}

Java does not allow abstract variables and/or constructor definitions in interfaces. Solution: Simply hang an abstract class between your interface and your implementation which only extends the abstract class like so:

 public interface IMyClass {

     void methodA();
     String methodB();
     Integer methodC();

 }

 public abstract class myAbstractClass implements IMyClass {
     protected String varA, varB;

     //Constructor
     myAbstractClass(String varA, String varB) {
         this.varA = varA;
         this.varB = VarB;
     }

     //Implement (some) interface methods here or leave them for the concrete class
     protected void methodA() {
         //Do something
     }

     //Add additional methods here which must be implemented in the concrete class
     protected abstract Long methodD();

     //Write some completely new methods which can be used by all subclasses
     protected Float methodE() {
         return 42.0;
     }

 }

 public class myConcreteClass extends myAbstractClass {

     //Constructor must now be implemented!
     myClass(String varA, String varB) {
         super(varA, varB);
     }

     //All non-private variables from the abstract class are available here
     //All methods not implemented in the abstract class must be implemented here

 }

You can also use an abstract class without any interface if you are SURE that you don't want to implement it along with other interfaces later. Please note that you can't create an instance of an abstract class you MUST extend it first.

(The "protected" keyword means that only extended classes can access these methods and variables.)

spyro

To avoid an input with only spaces, use: "[a-zA-Z0-9]+[a-zA-Z0-9 ]+".

eg: abc | abc aBc | abc 123 AbC 938234

To ensure, for example, that a first AND last name are entered, use a slight variation like

"[a-zA-Z]+[ ][a-zA-Z]+"

eg: abc def

As the documentation clearly states, Character.getNumericValue() returns the character's value as a digit.
It returns -1 if the character is not a digit.

If you want to get the numeric Unicode code point of a boxed Character object, you'll need to unbox it first:

int value = (int)c.charValue();

Android brute force will not work if your both the passwords are different so the best option might be like that try to find the file named as

log.idea

in your C:/users/your named account then you might found that in there in android folder open that file lpg.idea in notepad and then search for

alias

using find option in notepad you will find it that the password and alias and alias passwors has been shown there

adding my answer too, someone might find it useful or may be correct mine too.

Using Java 8 APIs, 

    List<Long> empNoList = Arrays.asList(1234, 7678, 2432, 9756556, 3354646);

    List<String> parameters = new ArrayList<>();

    String commaSepParameters = String.join(",", parameters); //Use String to join '?' with ','

StringBuilder selectQuery = new StringBuilder().append("SELECT COUNT(EMP_ID) FROM EMPLOYEE WHERE EMP_ID IN (").append(commaSepParameters).append(")");

I got this same error when i was trying to make a table with name "admin". Then I used @Table annotation and gave table a different name like @Table(name = "admins"). I think some words are reserved (like :- keywords in java) and you can not use them.

@Entity
@Table(name = "admins")
public class Admin extends TrackedEntity {

}

In my case, I was having two different versions of the below implementation in two different modules, So i changed both implementation to versions ie : 6.0.2 and it worked. You may also need to write dependency resolution see the accepted answer.

app module

implementation 'com.karumi:dexter:5.0.0'

commons module

implementation 'com.karumi:dexter:6.0.2'

I have tried this code and It's working fine in my case.

DELETE FROM NG_USR_0_CLIENT_GRID_NEW WHERE rowid IN
( SELECT rowid FROM
  (
      SELECT wi_name, relationship, ROW_NUMBER() OVER (ORDER BY rowid DESC) RN

      WHERE wi_name = 'NB-0000001385-Process'
  )
  WHERE RN=2

Your code works fine for me. It replaced the text in the file as expected and didn't append.

If you wanted to append, you set the second parameter in

new FileWriter(fnew,false);

to true;

SyntaxError: Unexpected token o in JSON

This also happens when you forget to use the await keyword for a method that returns JSON data.

For example:

async function returnJSONData()
{
   return "{\"prop\": 2}";
}

var json_str = returnJSONData();
var json_obj = JSON.parse(json_str);

will throw an error because of the missing await. What is actually returned is a Promise [object], not a string.

To fix just add await as you're supposed to:

var json_str = await returnJSONData();

This should be pretty obvious, but the error is called on JSON.parse, so it's easy to miss if there's some distance between your await method call and the JSON.parse call.

As a number of people have pointed out, disabling the submit button has some negative side effects (at least in Chrome it prevents the name/value of the button pressed from being submitted). My solution was to simply add an attribute to indicate that submit has been requested, and then check for the presence of this attribute on every submit. Because I'm using the submit function, this is only called after all HTML 5 validation is successful. Here is my code:

  $("form.myform").submit(function (e) {
    // Check if we have submitted before
    if ( $("#submit-btn").attr('attempted') == 'true' ) {
      //stop submitting the form because we have already clicked submit.
      e.preventDefault();
    }
    else {
      $("#submit-btn").attr("attempted", 'true');
    }
  });

Yes: simply press and hold the Alt key, click and drag to select the lines whose columns you wish to edit, and begin typing.

You can also go to Settings > Preferences..., and in the Editing tab, turn on multi-editing, to enable selection of multiple separate regions or columns of text to edit at once.

It's much more intuitive, as you can see your edits live as you type.

Technically, ANSI should be the same as US-ASCII. It refers to the ANSI X3.4 standard, which is simply the ANSI organisation's ratified version of ASCII. Use of the top-bit-set characters is not defined in ASCII/ANSI as it is a 7-bit character set.

However years of misuse of the term by the DOS and subsequently Windows community has left its practical meaning as “the system codepage of whatever machine is being used”. The system codepage is also sometimes known as ‘mbcs’, since on East Asian systems that can be a multiple-byte-per-character encoding. Some code pages can even use top-bit-clear bytes as trailing bytes in a multibyte sequence, so it's not even strict compatible with plain ASCII... but even then, it's still called “ANSI”.

On US and Western European default settings, “ANSI” maps to Windows code page 1252. This is not the same as ISO-8859-1 (although it is quite similar). On other machines it could be anything else at all. This makes “ANSI” utterly useless as an external encoding identifier.

if you have the BluetoothDevice object you can create bond(pair) from api 19 onwards with bluetoothDevice.createBond() method.

Edit

for callback, if the request was accepted or denied you will have to create a BroadcastReceiver with BluetoothDevice.ACTION_BOND_STATE_CHANGED action

Problem description

JavaScript has no built-in general map type (sometimes called associative array or dictionary) which allows to access arbitrary values by arbitrary keys. JavaScript's fundamental data structure is the object, a special type of map which only accepts strings as keys and has special semantics like prototypical inheritance, getters and setters and some further voodoo.

When using objects as maps, you have to remember that the key will be converted to a string value via toString(), which results in mapping 5 and '5' to the same value and all objects which don't overwrite the toString() method to the value indexed by '[object Object]'. You might also involuntarily access its inherited properties if you don't check hasOwnProperty().

JavaScript's built-in array type does not help one bit: JavaScript arrays are not associative arrays, but just objects with a few more special properties. If you want to know why they can't be used as maps, look here.

Eugene's Solution

Eugene Lazutkin already described the basic idea of using a custom hash function to generate unique strings which can be used to look up the associated values as properties of a dictionary object. This will most likely be the fastest solution, because objects are internally implemented as hash tables.

• Note: Hash tables (sometimes called hash maps) are a particular implementation of the map concept using a backing array and lookup via numeric hash values. The runtime environment might use other structures (such as search trees or skip lists) to implement JavaScript objects, but as objects are the fundamental data structure, they should be sufficiently optimised.

In order to get a unique hash value for arbitrary objects, one possibility is to use a global counter and cache the hash value in the object itself (for example, in a property named __hash).

A hash function which does this is and works for both primitive values and objects is:

function hash(value) {
    return (typeof value) + ' ' + (value instanceof Object ?
        (value.__hash || (value.__hash = ++arguments.callee.current)) :
        value.toString());
}

hash.current = 0;

This function can be used as described by Eugene. For convenience, we will further wrap it in a Map class.

My Map implementation

The following implementation will additionally store the key-value-pairs in a doubly linked list in order to allow fast iteration over both keys and values. To supply your own hash function, you can overwrite the instance's hash() method after creation.

// Linking the key-value-pairs is optional.
// If no argument is provided, linkItems === undefined, i.e. !== false
// --> linking will be enabled
function Map(linkItems) {
    this.current = undefined;
    this.size = 0;

    if(linkItems === false)
        this.disableLinking();
}

Map.noop = function() {
    return this;
};

Map.illegal = function() {
    throw new Error("illegal operation for maps without linking");
};

// Map initialisation from an existing object
// doesn't add inherited properties if not explicitly instructed to:
// omitting foreignKeys means foreignKeys === undefined, i.e. == false
// --> inherited properties won't be added
Map.from = function(obj, foreignKeys) {
    var map = new Map;

    for(var prop in obj) {
        if(foreignKeys || obj.hasOwnProperty(prop))
            map.put(prop, obj[prop]);
    }

    return map;
};

Map.prototype.disableLinking = function() {
    this.link = Map.noop;
    this.unlink = Map.noop;
    this.disableLinking = Map.noop;
    this.next = Map.illegal;
    this.key = Map.illegal;
    this.value = Map.illegal;
    this.removeAll = Map.illegal;

    return this;
};

// Overwrite in Map instance if necessary
Map.prototype.hash = function(value) {
    return (typeof value) + ' ' + (value instanceof Object ?
        (value.__hash || (value.__hash = ++arguments.callee.current)) :
        value.toString());
};

Map.prototype.hash.current = 0;

// --- Mapping functions

Map.prototype.get = function(key) {
    var item = this[this.hash(key)];
    return item === undefined ? undefined : item.value;
};

Map.prototype.put = function(key, value) {
    var hash = this.hash(key);

    if(this[hash] === undefined) {
        var item = { key : key, value : value };
        this[hash] = item;

        this.link(item);
        ++this.size;
    }
    else this[hash].value = value;

    return this;
};

Map.prototype.remove = function(key) {
    var hash = this.hash(key);
    var item = this[hash];

    if(item !== undefined) {
        --this.size;
        this.unlink(item);

        delete this[hash];
    }

    return this;
};

// Only works if linked
Map.prototype.removeAll = function() {
    while(this.size)
        this.remove(this.key());

    return this;
};

// --- Linked list helper functions

Map.prototype.link = function(item) {
    if(this.size == 0) {
        item.prev = item;
        item.next = item;
        this.current = item;
    }
    else {
        item.prev = this.current.prev;
        item.prev.next = item;
        item.next = this.current;
        this.current.prev = item;
    }
};

Map.prototype.unlink = function(item) {
    if(this.size == 0)
        this.current = undefined;
    else {
        item.prev.next = item.next;
        item.next.prev = item.prev;
        if(item === this.current)
            this.current = item.next;
    }
};

// --- Iterator functions - only work if map is linked

Map.prototype.next = function() {
    this.current = this.current.next;
};

Map.prototype.key = function() {
    return this.current.key;
};

Map.prototype.value = function() {
    return this.current.value;
};

Example

The following script,

var map = new Map;

map.put('spam', 'eggs').
    put('foo', 'bar').
    put('foo', 'baz').
    put({}, 'an object').
    put({}, 'another object').
    put(5, 'five').
    put(5, 'five again').
    put('5', 'another five');

for(var i = 0; i++ < map.size; map.next())
    document.writeln(map.hash(map.key()) + ' : ' + map.value());

generates this output:

string spam : eggs
string foo : baz
object 1 : an object
object 2 : another object
number 5 : five again
string 5 : another five

Further considerations

PEZ suggested to overwrite the toString() method, presumably with our hash function. This is not feasible, because it doesn't work for primitive values (changing toString() for primitives is a very bad idea). If we want toString() to return meaningful values for arbitrary objects, we would have to modify Object.prototype, which some people (myself not included) consider verboten.

The current version of my Map implementation as well as other JavaScript goodies can be obtained from here.

?vector

X <- vector(mode="character", length=10)

This will give you empty strings which get printed as two adjacent double quotes, but be aware that there are no double-quote characters in the values themselves. That's just a side-effect of how print.default displays the values. They can be indexed by location. The number of characters will not be restricted, so if you were expecting to get 10 character element you will be disappointed.

>  X[5] <- "character element in 5th position"

>  X
 [1] ""                                  ""                                 
 [3] ""                                  ""                                 
 [5] "character element in 5th position" ""                                 
 [7] ""                                  ""                                 
 [9] ""                                  "" 
>  nchar(X)
 [1]  0  0  0  0 33  0  0  0  0  0

> length(X)
[1] 10

For those of you landing here but searching how to break out of a loop that contains an include statement use return instead of break or continue.

<?php

for ($i=0; $i < 100; $i++) { 
    if (i%2 == 0) {
        include(do_this_for_even.php);
    }
    else {
        include(do_this_for_odd.php);
    }
}

?>

If you want to break when being inside do_this_for_even.php you need to use return. Using break or continue will return this error: Cannot break/continue 1 level. I found more details here

It's because of the requirement for separate compilation and because templates are instantiation-style polymorphism.

Lets get a little closer to concrete for an explanation. Say I've got the following files:

• foo.h
  • declares the interface of class MyClass<T>
• foo.cpp
  • defines the implementation of class MyClass<T>
• bar.cpp
  • uses MyClass<int>

Separate compilation means I should be able to compile foo.cpp independently from bar.cpp. The compiler does all the hard work of analysis, optimization, and code generation on each compilation unit completely independently; we don't need to do whole-program analysis. It's only the linker that needs to handle the entire program at once, and the linker's job is substantially easier.

bar.cpp doesn't even need to exist when I compile foo.cpp, but I should still be able to link the foo.o I already had together with the bar.o I've only just produced, without needing to recompile foo.cpp. foo.cpp could even be compiled into a dynamic library, distributed somewhere else without foo.cpp, and linked with code they write years after I wrote foo.cpp.

"Instantiation-style polymorphism" means that the template MyClass<T> isn't really a generic class that can be compiled to code that can work for any value of T. That would add overhead such as boxing, needing to pass function pointers to allocators and constructors, etc. The intention of C++ templates is to avoid having to write nearly identical class MyClass_int, class MyClass_float, etc, but to still be able to end up with compiled code that is mostly as if we had written each version separately. So a template is literally a template; a class template is not a class, it's a recipe for creating a new class for each T we encounter. A template cannot be compiled into code, only the result of instantiating the template can be compiled.

So when foo.cpp is compiled, the compiler can't see bar.cpp to know that MyClass<int> is needed. It can see the template MyClass<T>, but it can't emit code for that (it's a template, not a class). And when bar.cpp is compiled, the compiler can see that it needs to create a MyClass<int>, but it can't see the template MyClass<T> (only its interface in foo.h) so it can't create it.

If foo.cpp itself uses MyClass<int>, then code for that will be generated while compiling foo.cpp, so when bar.o is linked to foo.o they can be hooked up and will work. We can use that fact to allow a finite set of template instantiations to be implemented in a .cpp file by writing a single template. But there's no way for bar.cpp to use the template as a template and instantiate it on whatever types it likes; it can only use pre-existing versions of the templated class that the author of foo.cpp thought to provide.

You might think that when compiling a template the compiler should "generate all versions", with the ones that are never used being filtered out during linking. Aside from the huge overhead and the extreme difficulties such an approach would face because "type modifier" features like pointers and arrays allow even just the built-in types to give rise to an infinite number of types, what happens when I now extend my program by adding:

• baz.cpp
  • declares and implements class BazPrivate, and uses MyClass<BazPrivate>

There is no possible way that this could work unless we either

1. Have to recompile foo.cpp every time we change any other file in the program, in case it added a new novel instantiation of MyClass<T>
2. Require that baz.cpp contains (possibly via header includes) the full template of MyClass<T>, so that the compiler can generate MyClass<BazPrivate> during compilation of baz.cpp.

Nobody likes (1), because whole-program-analysis compilation systems take forever to compile , and because it makes it impossible to distribute compiled libraries without the source code. So we have (2) instead.

                    _kbSize = intersectRect.size
                }
                print("Your Keyboard Size \(_kbSize)")
            }
        }
    }

I am not certain if this meets your requirements, given I think you are interested in making the file readable by people, but if that's not a primary concern, just pickle it.

To save it:

import pickle

my_data = {'a': [1, 2.0, 3, 4+6j],
           'b': ('string', u'Unicode string'),
           'c': None}
output = open('data.pkl', 'wb')
pickle.dump(my_data, output)
output.close()

To read it back:

import pprint, pickle

pkl_file = open('data.pkl', 'rb')

data1 = pickle.load(pkl_file)
pprint.pprint(data1)

pkl_file.close()

• GitHub

  git config --global url.ssh://[email protected]/.insteadOf https://github.com/
  

• BitBucket

  git config --global url.ssh://[email protected]/.insteadOf https://bitbucket.org/
  

That tells git to always use SSH instead of HTTPS when connecting to GitHub/BitBucket, so you'll authenticate by certificate by default, instead of being prompted for a password.

You probably need to chdir to the correct directory before calling the script. This way you can ensure what directory your script is "in" before calling the shell command.

$old_path = getcwd();
chdir('/my/path/');
$output = shell_exec('./script.sh var1 var2');
chdir($old_path);

First, install with git+git or git+https, in any way you know. Example of installing kronok's branch of the brabeion project:

pip install -e git+https://github.com/kronok/brabeion.git@12efe6aa06b85ae5ff725d3033e38f624e0a616f#egg=brabeion

Second, use pip freeze > requirements.txt to get the right thing in your requirements.txt. In this case, you will get

-e git+https://github.com/kronok/brabeion.git@12efe6aa06b85ae5ff725d3033e38f624e0a616f#egg=brabeion-master

Third, test the result:

pip uninstall brabeion
pip install -r requirements.txt

This error may occur when you are adding an app in INSTALLED_APPS in the settings.py file but you do not have that app installed in your computer. You have two solution:

1. Install that app using package managers like pip in ubuntu
2. Or Comment out that installed app in the settings.py file

This error may also arise if you are not in your virtual environment which you may have created for your project.

You can use

 ../

to mean up one level. If you have a page called page2.html in the same folder as page.html then the relative path is:

 page2.html.

If you have page2.html at the same level with folder then the path is:

  ../page2.html

you have to use collections to return more then one return values

in your case you write your code as

public static List something(){
        List<Integer> list = new ArrayList<Integer>();
        int number1 = 1;
        int number2 = 2;
        list.add(number1);
        list.add(number2);
        return list;
    }

    // Main class code
    public static void main(String[] args) {
      something();
      List<Integer> numList = something();
    }

remove the .git folder in your project root folder

if you installed submodules and want to remove their git, also remove .git from submodules folders

You provide credentials in a URLRequest instance, like this in Swift 3:

let username = "user"
let password = "pass"
let loginString = String(format: "%@:%@", username, password)
let loginData = loginString.data(using: String.Encoding.utf8)!
let base64LoginString = loginData.base64EncodedString()

// create the request
let url = URL(string: "http://www.example.com/")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")

// fire off the request
// make sure your class conforms to NSURLConnectionDelegate
let urlConnection = NSURLConnection(request: request, delegate: self)

Or in an NSMutableURLRequest in Swift 2:

// set up the base64-encoded credentials
let username = "user"
let password = "pass"
let loginString = NSString(format: "%@:%@", username, password)
let loginData: NSData = loginString.dataUsingEncoding(NSUTF8StringEncoding)!
let base64LoginString = loginData.base64EncodedStringWithOptions([])

// create the request
let url = NSURL(string: "http://www.example.com/")
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "POST"
request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")

// fire off the request
// make sure your class conforms to NSURLConnectionDelegate
let urlConnection = NSURLConnection(request: request, delegate: self)

Here, to get the text of the menu that triggered the event (does not seem to have any id):

 $(document).ready(function() 
 {
    $('ul.art-vmenu li').click(function(e) 
    { 
     alert($(this).find("span.t").text());
    });
 });

I'm not sure you have gotten past this yet, but I had to work on something very similar today and I got your fiddle working like you are asking, basically what I did was make another table row under it, and then used the accordion control. I tried using just collapse but could not get it working and saw an example somewhere on SO that used accordion.

Here's your updated fiddle: http://jsfiddle.net/whytheday/2Dj7Y/11/

Since I need to post code here is what each collapsible "section" should look like ->

<tr data-toggle="collapse" data-target="#demo1" class="accordion-toggle">
    <td>1</td>
    <td>05 May 2013</td>
    <td>Credit Account</td>
    <td class="text-success">$150.00</td>
    <td class="text-error"></td>
    <td class="text-success">$150.00</td>
</tr>

<tr>
    <td colspan="6" class="hiddenRow">
        <div class="accordion-body collapse" id="demo1">Demo1</div>
    </td>
</tr>

If the shell scripts start with #!/bin/bash, they will always run with bash from /bin. If they however start with #!/usr/bin/env bash, they will search for bash in $PATH and then start with the first one they can find.

Why would this be useful? Assume you want to run bash scripts, that require bash 4.x or newer, yet your system only has bash 3.x installed and currently your distribution doesn't offer a newer version or you are no administrator and cannot change what is installed on that system.

Of course, you can download bash source code and build your own bash from scratch, placing it to ~/bin for example. And you can also modify your $PATH variable in your .bash_profile file to include ~/bin as the first entry (PATH=$HOME/bin:$PATH as ~ will not expand in $PATH). If you now call bash, the shell will first look for it in $PATH in order, so it starts with ~/bin, where it will find your bash. Same thing happens if scripts search for bash using #!/usr/bin/env bash, so these scripts would now be working on your system using your custom bash build.

One downside is, that this can lead to unexpected behavior, e.g. same script on the same machine may run with different interpreters for different environments or users with different search paths, causing all kind of headaches.

The biggest downside with env is that some systems will only allow one argument, so you cannot do this #!/usr/bin/env <interpreter> <arg>, as the systems will see <interpreter> <arg> as one argument (they will treat it as if the expression was quoted) and thus env will search for an interpreter named <interpreter> <arg>. Note that this is not a problem of the env command itself, which always allowed multiple parameters to be passed through but with the shebang parser of the system that parses this line before even calling env. Meanwhile this has been fixed on most systems but if your script wants to be ultra portable, you cannot rely that this has been fixed on the system you will be running.

It can even have security implications, e.g. if sudo was not configured to clean environment or $PATH was excluded from clean up. Let me demonstrate this:

Usually /bin is a well protected place, only root is able to change anything there. Your home directory is not, though, any program you run is able to make changes to it. That means malicious code could place a fake bash into some hidden directory, modify your .bash_profile to include that directory in your $PATH, so all scripts using #!/usr/bin/env bash will end up running with that fake bash. If sudo keeps $PATH, you are in big trouble.

E.g. consider a tool creates a file ~/.evil/bash with the following content:

#!/bin/bash

if [ $EUID -eq 0 ]; then
  echo "All your base are belong to us..."
  # We are root - do whatever you want to do
fi

/bin/bash "$@"

Let's make a simple script sample.sh:

#!/usr/bin/env bash

echo "Hello World"

Proof of concept (on a system where sudo keeps $PATH):

$ ./sample.sh
Hello World

$ sudo ./sample.sh
Hello World

$ export PATH="$HOME/.evil:$PATH"

$ ./sample.sh
Hello World

$ sudo ./sample.sh
All your base are belong to us...
Hello World

Usually the classic shells should all be located in /bin and if you don't want to place them there for whatever reason, it's really not an issue to place a symlink in /bin that points to their real locations (or maybe /bin itself is a symlink), so I would always go with #!/bin/sh and #!/bin/bash. There's just too much that would break if these wouldn't work anymore. It's not that POSIX would require these position (POSIX does not standardize path names and thus it doesn't even standardize the shebang feature at all) but they are so common, that even if a system would not offer a /bin/sh, it would probably still understand #!/bin/sh and know what to do with it and may it only be for compatibility with existing code.

But for more modern, non standard, optional interpreters like Perl, PHP, Python, or Ruby, it's not really specified anywhere where they should be located. They may be in /usr/bin but they may as well be in /usr/local/bin or in a completely different hierarchy branch (/opt/..., /Applications/..., etc.). That's why these often use the #!/usr/bin/env xxx shebang syntax.

Try this:

        //Write some information in the cells or do what you want
        XSSFRow row1 = sheet.createRow(0);
        XSSFCell r1c2 = row1.createCell(0);
        r1c2.setCellValue("NAME");
        XSSFCell r1c3 = row1.createCell(1);

        String sName = wb.getSheetName(i);
        if (sName.startsWith(prefix))
            count++;
    }

    if (count > 0) {
        sheet = wb.createSheet(prefix + count);
    } else
        sheet = wb.createSheet(prefix);

    if (isHidden)
        wb.setSheetHidden(wb.getNumberOfSheets() - 1, XSSFWorkbook.SHEET_STATE_VERY_HIDDEN);

        return sheet;
    }

}

if you want to fill all the column:

update 'column' set 'info' where keyID!=0;

In my case the sql server version on my localhost is higher than that on the production server and hence some new variables were added to the generated script from the localhost. This caused errors in creating the table in the first place. Since the creation of the table failed, subsequent query on the "NON EXISITING" table also failed. Luckily, in among the long list of the sql errors, I found this "OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF" to be the new varialbe in the script causing my issue. I did a search and replace and the error went away. Hope it helps someone.

$("#id").select2("val", null); //this will not work..you can try

You should actually do this...intialise and then set the value..well this is also the way it worked for me.

$("#id").select2().select2("val", null);
$("#id").select2().select2("val", 'oneofthevaluehere');

Just to put this here for posterity sake, in 2.6 the "start" parameter was added to enumerate like so:

enumerate(sequence, start=1)

That's because the event onsubmit is triggered before the form is submitted.

Remove your onSubmit and output that JavaScript in your PHP script after you have processed the request. You are closing the window right now, and cancelling the request to your server.

As Delan said, you want to use a combination of addEventListener for newer versions, and attachEvent for older ones.

You'll find more information about event listeners on MDN. (Note there are some caveats with the value of 'this' in your listener).

You can also use a framework like jQuery to abstract the event handling altogether.

$("#someelementid").bind("click", function (event) {
   // etc... $(this) is whetver caused the event
});

I too found Python lacking when it comes to reading and writing binary files, so I wrote a small module (for Python 3.6+).

With binaryfile you'd do something like this (I'm guessing, since I don't know Fortran):

import binaryfile

def particle_file(f):
    f.array('group_ids')  # Declare group_ids to be an array (so we can use it in a loop)
    f.skip(4)  # Bytes 1-4
    num_particles = f.count('num_particles', 'group_ids', 4)  # Bytes 5-8
    f.int('num_groups', 4)  # Bytes 9-12
    f.skip(8)  # Bytes 13-20
    for i in range(num_particles):
        f.struct('group_ids', '>f')  # 4 bytes x num_particles
    f.skip(4)

with open('myfile.bin', 'rb') as fh:
    result = binaryfile.read(fh, particle_file)
print(result)

Which produces an output like this:

{
    'group_ids': [(1.0,), (0.0,), (2.0,), (0.0,), (1.0,)],
    '__skipped': [b'\x00\x00\x00\x08', b'\x00\x00\x00\x08\x00\x00\x00\x14', b'\x00\x00\x00\x14'],
    'num_particles': 5,
    'num_groups': 3
}

I used skip() to skip the additional data Fortran adds, but you may want to add a utility to handle Fortran records properly instead. If you do, a pull request would be welcome.

Using Jupyter Notebook, the code can be as simple as the following.

%matplotlib inline
from IPython.display import Image
Image('your_image.png')

Sometimes you might would like to display a series of images in a for loop, in which case you might would like to combine display and Image to make it work.

%matplotlib inline
from IPython.display import display, Image
for your_image in your_images:
    display(Image('your_image'))

import java.util.Random;

public class RandomSSNTest {

    public static void main(String args[]) {
        generateDummySSNNumber();
    }


    //831-33-6049
    public static void generateDummySSNNumber() {
        Random random = new Random();

        int id1 = random.nextInt(1000);//3
        int id2 = random.nextInt(100);//2
        int id3 = random.nextInt(10000);//4

        System.out.print((id1+"-"+id2+"-"+id3));
    }

}

You can also use

import java.util.concurrent.ThreadLocalRandom;
Random random = ThreadLocalRandom.current();

However, this class doesn’t perform well in a multi-threaded environment.

We can say like DispatcherServlet taking care of everything in Spring MVC.

At web container start up:

1. DispatcherServlet will be loaded and initialized by calling init() method
2. init() of DispatcherServlet will try to identify the Spring Configuration Document with naming conventions like "servlet_name-servlet.xml" then all beans can be identified.

Example:

public class DispatcherServlet extends HttpServlet {

    ApplicationContext ctx = null;

    public void init(ServletConfig cfg){
        // 1. try to get the spring configuration document with default naming conventions
        String xml = "servlet_name" + "-servlet.xml";

        //if it was found then creates the ApplicationContext object
        ctx = new XmlWebApplicationContext(xml);
    }
    ...
}

So, in generally DispatcherServlet capture request URI and hand over to HandlerMapping. HandlerMapping search mapping bean with method of controller, where controller returning logical name(view). Then this logical name is send to DispatcherServlet by HandlerMapping. Then DispatcherServlet tell ViewResolver to give full location of view by appending prefix and suffix, then DispatcherServlet give view to the client.

Example:

SELECT TRIM('   Sample   ');

Result: 'Sample'

UPDATE TableName SET ColumnName = TRIM(ColumnName)

In UWP:

await Launcher.LaunchUriAsync(new Uri("http://google.com"));

For those looking for an inline example, here is one:

<audio controls style="width: 200px;">
   <source src="http://somewhere.mp3" type="audio/mpeg">
</audio>

It doesn't seem to respect a "height" setting, at least not awesomely. But you can always "customize" the controls but creating your own controls (instead of using the built-in ones) or using somebody's widget that similarly creates its own :)

I would also like to offer an alternative solution to this problem.

Assuming all your keys are numeric without any gaps, my preferred method is to count the array then minus 1 from that value (to account for the fact that array keys start at 0.

$array = array(0=>'dog', 1=>'cat');

$lastKey = count($array)-1;
$lastKeyValue = $array[$lastKey];

var_dump($lastKey);
print_r($lastKeyValue);

This would give you:

int(1) cat

Make sure that your ORACLE_HOME and ORACLE_SID are correct To see the current values in windows, at the command prompt type

echo %ORACLE_HOME%

Then

echo %ORACLE_SID%

If the values are not your current oracle home and SID you need to correct them. This can be done in Windows environment variables.

I replaced all the single quotes ['] to double quotes ["] and then it worked perfectly. Thanks for the input by @LogicalKip.

request.data will be empty if request.headers["Content-Type"] is recognized as form data, which will be parsed into request.form. To get the raw data regardless of content type, use request.get_data().

request.data calls request.get_data(parse_form_data=True), which results in the different behavior for form data.

There is nice tiny library to work with utf8 from c++: utfcpp

Try to use the function DECODE

Ex: Decode(MYDATE, NULL, ' ', MYDATE)

If date is NULL then display ' ' (BLANK) else display the date.

java packages are base, and javax packages are extensions.

Swing was an extension because AWT was the original UI API. Swing came afterwards, in version 1.1.

why you dont just dump the mysql database but with extension when you run without --single-transaction you will interrupt the connection to other clients:

mysqldump --host=hostname.de --port=0000 --user=username --password=password --single-transaction --skip-add-locks --skip-lock-tables --default-character-set=utf8 datenbankname > mysqlDBBackup.sql 

after that read out the file and search for what you want.... in Strings.....

Assuming it is OK that the operation is not atomic, you can do:

if (std::ifstream(name))
{
     std::cout << "File already exists" << std::endl;
     return false;
}
std::ofstream file(name);
if (!file)
{
     std::cout << "File could not be created" << std::endl;
     return false;
}
... 

Note that this doesn't work if you run multiple threads trying to create the same file, and certainly will not prevent a second process from "interfering" with the file creation because you have TOCTUI problems. [We first check if the file exists, and then create it - but someone else could have created it in between the check and the creation - if that's critical, you will need to do something else, which isn't portable].

A further problem is if you have permissions such as the file is not readable (so we can't open it for read) but is writeable, it will overwrite the file.

In MOST cases, neither of these things matter, because all you care about is telling someone that "you already have a file like that" (or something like that) in a "best effort" approach.

Contributing to ferrix example,

class Battery():

    def __init__(self, battery_size = 60):
        self.battery_size = battery_size
    def get_range(self):
        if self.battery_size == 70:
            range = 240
        elif self.battery_size == 85:
        range = 270

        message = "This car can go approx " + str(range)
        message += "Fully charge"
        print(message)

My message will not execute, because none of my conditions are fulfill therefore receiving " UnboundLocalError: local variable 'range' referenced before assignment"

def get_range(self):
    if self.battery_size <= 70:
        range = 240
    elif self.battery_size >= 85:
        range = 270

git clone --filter from git 2.19 now works on GitHub (tested 2020-09-18, git 2.25.1)

I'm not sure about pull/fetch, but at least for the initial clone, this option was added together with an update to the remote protocol, and it truly prevents objects from being downloaded from the server.

E.g., to clone only objects required for d1 of this repository: https://github.com/cirosantilli/test-git-partial-clone I can do:

git clone \
  --depth 1 \
  --filter=blob:none \
  --no-checkout \
  https://github.com/cirosantilli/test-git-partial-clone \
;
cd test-git-partial-clone
git checkout master -- d1

I have covered this in more detail at: Git: How do I clone a subdirectory only of a Git repository?

It is very likely that whatever gets implemented for git clone in that area will also have git pull analogues, but I couldn't find it very easily yet.

I struggled with this issue for a long time... My solution was to modify the php.ini file, in the folder that contained the php script. This was important, as modifying the php.ini at the root did not resolve the problem (I have a php.ini in each folder for granular control). The relevant entries in my php.ini looked like this.... (the output_buffering is not likely needed for this issue)

output_buffering = On 
upload_max_filesize = 20M 
post_max_size = 21M

I've just checked and i have the same code as you and it works perferctly. The only difference is how i fill my List for the params :

I use a : ArrayList<BasicNameValuePair> params

and fill it this way :

 params.add(new BasicNameValuePair("apikey", apikey);

I do not use any JSONObject to send params to the webservices.

Are you obliged to use the JSONObject ?

There is no single magic function to force a frame to a minimum or fixed size. However, you can certainly force the size of a frame by giving the frame a width and height. You then have to do potentially two more things: when you put this window in a container you need to make sure the geometry manager doesn't shrink or expand the window. Two, if the frame is a container for other widget, turn grid or pack propagation off so that the frame doesn't shrink or expand to fit its own contents.

Note, however, that this won't prevent you from resizing a window to be smaller than an internal frame. In that case the frame will just be clipped.

import Tkinter as tk

root = tk.Tk()
frame1 = tk.Frame(root, width=100, height=100, background="bisque")
frame2 = tk.Frame(root, width=50, height = 50, background="#b22222")

frame1.pack(fill=None, expand=False)
frame2.place(relx=.5, rely=.5, anchor="c")

root.mainloop()

There are two ways to doing the same:

1. You may set the value of android:divider="#FFCCFF" in layout xml file. With this you also have to specify height of divider like this android:dividerHeight="5px".

   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="match_parent">
   
     <ListView 
     android:id="@+id/lvMyList"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:divider="#FFCCFF"
     android:dividerHeight="5px"/>
   
   </LinearLayout>
   

2. You may also do this by programmatically...

   ListView listView = getListView();
   ColorDrawable myColor = new ColorDrawable(
       this.getResources().getColor(R.color.myColor)
   );
   listView.setDivider(myColor);
   listView.setDividerHeight();
   

If you are interested in getting an array of either numbers or strings, you could define a type that will take an array of either

type Tuple = Array<number | string>
const example: Tuple = [1, "message"]
const example2: Tuple = ["message", 1]

If you expect an array of a specific order (i.e. number and a string)

type Tuple = [number, string]
const example: Tuple = [1, "message"]
const example2: Tuple = ["messsage", 1] // Type 'string' is not assignable to type 'number'.

You don't have to use Javascript to do this. Using plain-old css:

div.blah {
  position:absolute;
  top: 0; /*[wherever you want it]*/
  left:0; /*[wherever you want it]*/
}

If you feel you must use javascript, or are trying to do this dynamically Using JQuery, this affects all divs of class "blah":

var blahclass =  $('.blah'); 
blahclass.css('position', 'absolute');
blahclass.css('top', 0); //or wherever you want it
blahclass.css('left', 0); //or wherever you want it

Alternatively, if you must use regular old-javascript you can grab by id

var domElement = document.getElementById('myElement');// don't go to to DOM every time you need it. Instead store in a variable and manipulate.
domElement.style.position = "absolute";
domElement.style.top = 0; //or whatever 
domElement.style.left = 0; // or whatever

Since Postgres 9.2 there is also the option to specify a connection string or URI that can contain the username and password.

Using that is a security risk because the password is visible in plain text when looking at the command line of a running process e.g. using ps (Linux), ProcessExplorer (Windows) or similar tools, by other users.

The usual way to do it is as outlined by Guffa, nested elements. It's a bit sad having to add extra markup to get the hooks you need for this, but in practice a wrapper div here or there isn't going to hurt anyone.

If you must do it without extra elements (eg. when you don't have control of the page markup), you can use box-sizing, which has pretty decent but not complete or simple browser support. Likely more fun than having to rely on scripting though.

Add a second });.

When properly indented, your code reads

$(function() {
    $("#mewlyDiagnosed").hover(function() {
        $("#mewlyDiagnosed").animate({'height': '237px', 'top': "-75px"});
    }, function() {
        $("#mewlyDiagnosed").animate({'height': '162px', 'top': "0px"});
    });
MISSING!

You never closed the outer $(function() {.

a.button:hover{
    background: #383;  }

works for me but in my case

#buttonClick:hover {
background-color:green;  }

I'm not sure what wget is, but to get a file from the web and store it locally, you can use NSData:

NSString *stringURL = @"http://www.somewhere.com/thefile.png";
NSURL  *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
  NSArray       *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSString  *documentsDirectory = [paths objectAtIndex:0];  

  NSString  *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"filename.png"];
  [urlData writeToFile:filePath atomically:YES];
}

I've continued to research this item myself, and it does appear to remain beyond us at this point.

I even tried buying a Apple Composite AV Cable, but it doesn't capture screen, just video playing like YouTube, etc.

So I decided to go with the iShowU path and that has worked out well so far.

Thanks Guys!

Upgrading mod_php with Apache

This section describes the upgrade process for a system using Apache as the web server and mod_php to execute PHP code. If, instead, you are running Nginx and PHP-FPM, skip ahead to the next section.

Begin by removing existing PHP packages. Press y and hit Enter to continue when prompted.

sudo yum remove php-cli mod_php php-common

Install the new PHP 7 packages from IUS. Again, press y and Enter when prompted.

sudo yum install mod_php70u php70u-cli php70u-mysqlnd

Finally, restart Apache to load the new version of mod_php:

sudo apachectl restart

You can check on the status of Apache, which is managed by the httpd systemd unit, using systemctl:

systemctl status httpd

Just send xml bytes directly:

#!/usr/bin/env python2
# -*- coding: utf-8 -*-
import requests

xml = """<?xml version='1.0' encoding='utf-8'?>
<a>?</a>"""
headers = {'Content-Type': 'application/xml'} # set what your server accepts
print requests.post('http://httpbin.org/post', data=xml, headers=headers).text

Output

{
  "origin": "x.x.x.x",
  "files": {},
  "form": {},
  "url": "http://httpbin.org/post",
  "args": {},
  "headers": {
    "Content-Length": "48",
    "Accept-Encoding": "identity, deflate, compress, gzip",
    "Connection": "keep-alive",
    "Accept": "*/*",
    "User-Agent": "python-requests/0.13.9 CPython/2.7.3 Linux/3.2.0-30-generic",
    "Host": "httpbin.org",
    "Content-Type": "application/xml"
  },
  "json": null,
  "data": "<?xml version='1.0' encoding='utf-8'?>\n<a>\u0431</a>"
}

I guess you could try

table tr td { color: red; }
table tr td table tr td { color: black; }

Or

body table tr td { color: red; }

where 'body' is a selector for your table's parent

But classes are most likely the right way to go here.

you can use datetime module to get current Date and Time in Python 2.7

import datetime
print datetime.datetime.now()

Output :

2015-05-06 14:44:14.369392

Its not ideal but you can use a proxy server and it works fine. For example go to hidemyass.com put in www.google.com and put the link it goes to in an iframe and it works!
