One level up, I have used:

str_replace(basename(__DIR__) . '/' . basename(__FILE__), '', realpath(__FILE__)) . '/required.php';

or for php < 5.3:

str_replace(basename(dirname(__FILE__)) . '/' . basename(__FILE__), '', realpath(__FILE__)) . '/required.php';

In Python 3.4+ you can use the simpler pathlib module:

from inspect import currentframe, getframeinfo
from pathlib import Path

filename = getframeinfo(currentframe()).filename
parent = Path(filename).resolve().parent

You can also use __file__ to avoid the inspect module altogether:

from pathlib import Path
parent = Path(__file__).resolve().parent

use this : export MYVAR="$(dirname "$(dirname "$(dirname "$(dirname $PWD)")")")" if you want 4th parent directory

export MYVAR="$(dirname "$(dirname "$(dirname $PWD)")")" if you want 3rd parent directory

export MYVAR="$(dirname "$(dirname $PWD)")" if you want 2nd parent directory

var people = 
[{"name": 'a75',"item1": "false","item2":"false"}, 
{"name": 'z32',"item1": "true","item2":  "false"}, 
{"name": 'e77',"item1": "false","item2": "false"}]; 

function mycomparator(a,b) {   return parseInt(a.name) - parseInt(b.name);  } 
people.sort(mycomparator); 

something along the lines of this maybe (or as we used to say, this should work).

Have you seen this already? The cause seems to be a very old libpam on one of the sides, probably on that customer.

Or the links for the version might be missing : http://www.linux.org/docs/ldp/howto/Program-Library-HOWTO/shared-libraries.html

Since C++17 you can also use the standardized free function: std::size(container) which will return the amount of elements in that container.

example:

std::vector<int> vec = { 1, 2, 3, 4, 8 };
std::cout << std::size(vec) << "\n\n";    // 5

int A[] = {40,10,20};
std::cout << std::size(A) << '\n';      // 3

One better check that can be done if you get such error while accessing a file is to use the file.exists("file_path/file_name") function. This function will return TRUE if the file is existing and accessible, else False.

VMware? No. However, QEMU has an x86_64 system target that you can use. You likely won't be able to use a VMware image directly (IIRC, there's no conversion tool), but you can install the OS and such yourself and work inside it. QEMU can be a bit of a PITA to get up and running, but it tends to work quite nicely.

I found this blog posting by Aaron Hillegass (author, instructor, Cocoa ninja) to be very enlightening. Even if you don't adopt his modified approach to loading NIB files through a designated initializer you will probably at least get a better understanding of the process that's going on. I've been using this method lately to great success!

For older versions of jQuery

jQuery().jquery  (or)

jQuery().fn.jquery

For newer versions of jQuery

$().jquery  (or)

$().fn.jquery

Assuming you use the declarative style (i.e. ORM classes), it is pretty easy:

query = db_session.query(User.id, User.name).filter(User.id.in_([123,456]))
results = query.all()

db_session is your database session here, while User is the ORM class with __tablename__ equal to "users".

There are 2 major differences.

1. Technical
2. Licensing

Technical, there are 3 major differences:

First and foremost, Community doesn't have TFS support.
You'll just have to use git (arguable whether this constitutes a disadvantage or whether this actually is a good thing).
Note: This is what MS wrote. Actually, you can check-in&out with TFS as normal, if you have a TFS server in the network. You just cannot use Visual Studio as TFS SERVER.

Second, VS Community is severely limited in its testing capability.
Only unit tests. No Performance tests, no load tests, no performance profiling.

Third, VS Community's ability to create Virtual Environments has been severely cut.

On the other hand, syntax highlighting, IntelliSense, Step-Through debugging, GoTo-Definition, Git-Integration and Build/Publish are really all the features I need, and I guess that applies to a lot of developers.

For all other things, there are tools that do the same job faster, better and cheaper.

If you, like me, anyway use git, do unit testing with NUnit, and use Java-Tools to do Load-Testing on Linux plus TeamCity for CI, VS Community is more than sufficient, technically speaking.

Licensing:

A) If you're an individual developer (no enterprise, no organization), no difference (AFAIK), you can use CommunityEdition like you'd use the paid edition (as long as you don't do subcontracting)
B) You can use CommunityEdition freely for OpenSource (OSI) projects
C) If you're an educational insitution, you can use CommunityEdition freely (for education/classroom use)
D) If you're an enterprise with 250 PCs or users or more than one million US dollars in revenue (including subsidiaries), you are NOT ALLOWED to use CommunityEdition.
E) If you're not an enterprise as defined above, and don't do OSI or education, but are an "enterprise"/organization, with 5 or less concurrent (VS) developers, you can use VS Community freely (but only if you're the owner of the software and sell it, not if you're a subcontractor creating software for a larger enterprise, software which in the end the enterprise will own), otherwise you need a paid edition.

The above does not consitute legal advise.

I realize this is an old thread, but for those taking @JasonMArcher's accepted answer above as fact, I'm surprised it has not been corrected many of us have known for years it is actually the PIPELINE adding the delay and NOTHING to do with whether it is Out-Null or not. In fact, if you run the tests below you will quickly see that the same "faster" casting to [void] and $void= that for years we all used thinking it was faster, are actually JUST AS SLOW and in fact VERY SLOW when you add ANY pipelining whatsoever. In other words, as soon as you pipe to anything, the whole rule of not using out-null goes into the trash.

Proof, the last 3 tests in the list below. The horrible Out-null was 32339.3792 milliseconds, but wait - how much faster was casting to [void]? 34121.9251 ms?!? WTF? These are REAL #s on my system, casting to VOID was actually SLOWER. How about =$null? 34217.685ms.....still friggin SLOWER! So, as the last three simple tests show, the Out-Null is actually FASTER in many cases when the pipeline is already in use.

So, why is this? Simple. It is and always was 100% a hallucination that piping to Out-Null was slower. It is however that PIPING TO ANYTHING is slower, and didn't we kind of already know that through basic logic? We just may not have know HOW MUCH slower, but these tests sure tell a story about the cost of using the pipeline if you can avoid it. And, we were not really 100% wrong because there is a very SMALL number of true scenarios where out-null is evil. When? When adding Out-Null is adding the ONLY pipeline activity. In other words....the reason a simple command like $(1..1000) | Out-Null as shown above showed true.

If you simply add an additional pipe to Out-String to every test above, the #s change radically (or just paste the ones below) and as you can see for yourself, the Out-Null actually becomes FASTER in many cases:

No it's not a bug. Have a look at the Loose comparisons with == table (second table), which shows the result of comparing each value in the first column with the values in the other columns:

    TRUE    FALSE   1       0       -1      "1"     "0"     "-1"    NULL    array() "php"   ""

    [...]    

""  FALSE   TRUE    FALSE   TRUE    FALSE   FALSE   FALSE   FALSE   TRUE    FALSE   FALSE   TRUE

There you can see that an empty string "" compared with false, 0, NULL or "" will yield true.

You might want to use is_null ^[docs] instead, or strict comparison (third table).

I think there is no standard syntax for command line usage, but most use this convention:

Microsoft Command-Line Syntax, IBM has similar Command-Line Syntax

• Text without brackets or braces

  Items you must type as shown
  
  

• <Text inside angle brackets>

  Placeholder for which you must supply a value
  
  

• [Text inside square brackets]

  Optional items
  
  

• {Text inside braces}

  Set of required items; choose one
  
  

• Vertical bar {a|b}

  Separator for mutually exclusive items; choose one
  
  

• Ellipsis <file> …

  Items that can be repeated
  
  

Program prints ab, goes back one character and prints si overwriting the b resulting asi. Carriage return returns the caret to the first column of the current line. That means the ha will be printed over as and the result is hai

The Best way to wait without freezing your main thread is using the Task.Delay function.

So your code will look like this

var t = Task.Run(async delegate
{              
    dataGridView1.Rows[x1].Cells[y1].Style.BackColor = System.Drawing.Color.Red;
    dataGridView1.Refresh();
    await Task.Delay(1000);             
});

try this

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/linuxbrew/go/install)"

It's as simple as the one below, and works like a charm.

My solution perfectly answers your question: How to make JQuery-AJAX request synchronous

Set ajax to synchronous before the ajax call, and then reset it after your ajax call:

$.ajaxSetup({async: false});

$ajax({ajax call....});

$.ajaxSetup({async: true});

In your case it would look like this:

$.ajaxSetup({async: false});

$.ajax({
        type: "POST",
        async: "false",
        url: "checkpass.php",
        data: "password="+password,
        success: function(html) {
            var arr=$.parseJSON(html);
            if(arr == "Successful") {
                return true;
            } else {
                return false;
            }
        }
    });


$.ajaxSetup({async: true});

I hope it helps :)

Kotlin solution to move an Element from "fromPos" to "toPos" and shift all other items accordingly (useful for moving an item in a staggered layout recyclerView in an Android application)

            if(fromPos < toPos){                    
                val movingElement = myList[fromPos]
                //shifts all elements between fromPos and toPos 1 down
                for(i in fromPos+1..toPos){
                    myList[i-1] = myList[i]
                }
                //re-add element that was saved in the beginning
                myList[toPos] = movingElement
            }

            if(fromPos > toPos){
                val movingElement = myList[fromPos]
                //shifts elements between toPos and fromPos 1 up
                for(i in fromPos downTo toPos+1){
                    myList[i] = myList[i-1]
                }                    
                //re-add element that was saved in the beginning
                myList[toPos] = movingElement
            }

Actually asXML() converts the string into xml as it name says:

<id>5</id>

This will display normally on a web page but it will cause problems when you matching values with something else.

You may use strip_tags function to get real value of the field like:

$newString = strip_tags($xml->asXML());

PS: if you are working with integers or floating numbers, you need to convert it into integer with intval() or floatval().

$newNumber = intval(strip_tags($xml->asXML()));

Simply update with a convert/cast to INT:

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

Or convert:

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

To test you can do this:

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

I can handle this way:

select to_number(to_char(sysdate,'MI')) - to_number(to_char(*YOUR_DATA_VALUE*,'MI')),max(exp_time)  from ...

Or if you want to the hour just change the MI;

select to_number(to_char(sysdate,'HH24')) - to_number(to_char(*YOUR_DATA_VALUE*,'HH24')),max(exp_time)  from ...

the others don't work for me. Good luck.

You can do it this way:

xml.Descendants().Where(p => p.Name.LocalName == "Name of the node to find")

where xml is a XDocument.

Be aware that the property Name returns an object that has a LocalName and a Namespace. That's why you have to use Name.LocalName if you want to compare by name.

I was debugging a menu hover state with Chrome and did this to be able to see the hover state code:

In the Elements panel click over Toggle Element state button and select :hover.

In the Scripts panel go to Event Listeners Breakpoints in the right bottom section and select Mouse -> mouseup.

Now inspect the Menu and select the box you want. When you release the mouse button it should stop and show you the selected element hover state in the Elements panel (look at the Styles section).

Go to

I think this is the best way to change the port number also.

It works for me

It's sometimes desirable to filter elements based on whether they have data-items attached to them programmatically (aka not via dom-attributes):

$el.filter(function(i, x) { return $(x).data('foo-bar'); }).doSomething();

The above works but is not very readable. A better approach is to use a pseudo-selector for testing this sort of thing:

$.expr[":"].hasData = $.expr.createPseudo(function (arg) {
    return function (domEl) {
        var $el = $(domEl);
        return $el.is("[" + ((arg.startsWith("data-") ? "" : "data-") + arg) + "]") || typeof ($el.data(arg)) !== "undefined";
    };
});

Now we can refactor the original statement to something more fluent and readable:

$el.filter(":hasData('foo-bar')").doSomething();

I think you don't have a grunt.js file in your project directory. Use grunt:init, which gives you options such as jQuery, node,commonjs. Select what you want, then proceed. This really works. For more information you can visit this.

Do this:

 1. npm install -g grunt
 2. grunt:init  ( you will get following options ):
      jquery: A jQuery plugin
      node: A Node module
      commonjs: A CommonJS module
      gruntplugin: A Grunt plugin
      gruntfile: A Gruntfile (grunt.js)
 3 .grunt init:jquery (if you want to create a jQuery related project.).

It should work.

Solution for v1.4:

1. npm install -g grunt-cli
2. npm init
   fill all details and it will create a package.json file.
3. npm install grunt (for grunt dependencies.)

Edit : Updated solution for new versions:

 npm install grunt --save-dev

One possible approach, if you just need to specify a parameter once and replicate it in several places, is to do something like this:

SELECT
  str_size  /* my variable usage */
  , LPAD(TRUNC(DBMS_RANDOM.VALUE * POWER(10, str_size)), str_size, '0') rand
FROM
  dual  /* or any other table, or mixed of joined tables */
  CROSS JOIN (SELECT 8 str_size FROM dual);  /* my variable declaration */

This code generates a string of 8 random digits.

Notice that I create a kind of alias named str_size that holds the constant 8. It is cross-joined to be used more than once in the query.

If you want that all normal output of your Batch script be silent (like in your example), the easiest way to do that is to run the Batch file with a redirection:

C:\Temp> test.bat >nul

This method does not require to modify a single line in the script and it still show error messages in the screen. To supress all the output, including error messages:

C:\Temp> test.bat >nul 2>&1

If your script have lines that produce output you want to appear in screen, perhaps will be simpler to add redirection to those lineas instead of all the lines you want to keep silent:

@ECHO OFF
SET scriptDirectory=%~dp0
COPY %scriptDirectory%test.bat %scriptDirectory%test2.bat
FOR /F %%f IN ('dir /B "%scriptDirectory%*.noext"') DO (
del "%scriptDirectory%%%f"
)
ECHO
REM Next line DO appear in the screen
ECHO Script completed >con

Modified version of jockeisorby's answer that fixes the event handler not being properly removed.

copyToClipboard(item): void {
    let listener = (e: ClipboardEvent) => {
        e.clipboardData.setData('text/plain', (item));
        e.preventDefault();
    };

    document.addEventListener('copy', listener);
    document.execCommand('copy');
    document.removeEventListener('copy', listener);
}

The recent changes in the documentation mention a different way of removing a default option for less ("default options" being FRSX).

For this question, this would be (git 1.8+)

git config --global --replace-all core.pager 'less -+F -+X'

For example, Dirk Bester suggests in the comments:

export LESS="$LESS -FRXK" 

so that I get colored diff with Ctrl-C quit from less.

Wilson F mentions in the comments and in his question that:

less supports horizontal scrolling, so when lines are chopped off, less disables quit-if-one-screen so that the user can still scroll the text to the left to see what was cut off.

Those modifications were already visible in git 1.8.x, as illustrated in "Always use the pager for git diff" (see the comments). But the documentation just got reworded (for git 1.8.5 or 1.9, Q4 2013).

Text viewer for use by Git commands (e.g., 'less').
The value is meant to be interpreted by the shell.

The order of preference is:

• the $GIT_PAGER environment variable,
• then core.pager configuration,
• then $PAGER,
• and then the default chosen at compile time (usually 'less').

When the LESS environment variable is unset, Git sets it to FRSX
(if LESS environment variable is set, Git does not change it at all).

If you want to selectively override Git's default setting for LESS, you can set core.pager to e.g. less -+S.
This will be passed to the shell by Git, which will translate the final command to LESS=FRSX less -+S. The environment tells the command to set the S option to chop long lines but the command line resets it to the default to fold long lines.

See commit 97d01f2a for the reason behind the new documentation wording:

config: rewrite core.pager documentation

The text mentions core.pager and GIT_PAGER without giving the overall picture of precedence. Borrow a better description from the git var(1) documentation.

The use of the mechanism to allow system-wide, global and per-repository configuration files is not limited to this particular variable. Remove it to clarify the paragraph.

Rewrite the part that explains how the environment variable LESS is set to Git's default value, and how to selectively customize it.

Note: commit b327583 (Matthieu Moy moy, April 2014, for git 2.0.x/2.1, Q3 2014) will remove the S by default:

pager: remove 'S' from $LESS by default

By default, Git used to set $LESS to -FRSX if $LESS was not set by the user.
The FRX flags actually make sense for Git (F and X because sometimes the output Git pipes to less is short, and R because Git pipes colored output).
The S flag (chop long lines), on the other hand, is not related to Git and is a matter of user preference. Git should not decide for the user to change LESS's default.

More specifically, the S flag harms users who review untrusted code within a pager, since a patch looking like:

-old code;
+new good code; [... lots of tabs ...] malicious code;

would appear identical to:

-old code;
+new good code;

Users who prefer the old behavior can still set the $LESS environment variable to -FRSX explicitly, or set core.pager to 'less -S'.

The documentation will read:

The environment does not set the S option but the command line does, instructing less to truncate long lines.
Similarly, setting core.pager to less -+F will deactivate the F option specified by the environment from the command-line, deactivating the "quit if one screen" behavior of less.
One can specifically activate some flags for particular commands: for example, setting pager.blame to less -S enables line truncation only for git blame.

Get the current Windows username:

using System;

class Sample
{
    public static void Main()
    {
        Console.WriteLine();

        //  <-- Keep this information secure! -->
        Console.WriteLine("UserName: {0}", Environment.UserName);
    }
}

fist get the certificate from the provider
create a file ends wirth .cer and pase the certificate

copy the text file or  past   it  somewhere you can access it 
then use the cmd prompt as an admin and cd to the bin of the jdk,
the cammand that will be used is the:  keytool 

change the  password of the keystore with :

keytool  -storepasswd -keystore "path of the key store from c\ and down"

the password is : changeit 
 then you will be asked to enter the new password twice 

then type the following :

keytool -importcert -file  "C:\Program Files\Java\jdk-13.0.2\lib\security\certificateFile.cer"   -alias chooseAname -keystore  "C:\Program Files\Java\jdk-13.0.2\lib\security\cacerts"

As koala_dev used in his approach 1, I would prefer the offset method instead of center-block or margins which has limited usage, but as he mentioned:

Now, there's an obvious drawback for this method, it only works for even column sizes, so only .col-X-2, .col-X-4, col-X-6, col-X-8 and col-X-10 are supported.

This can be solved using the following approach for odd columns.

<div class="col-xs-offset-5 col-xs-2">
    <div class="col-xs-offset-3">
        // Your content here
    </div>
</div>

This worked for Red Hat Enterprise Linux Server release 6.4

sudo yum install mysql-devel
sudo yum install python-devel
pip install mysql-python

You've got the right idea, so here's how to go ahead: the onclick handlers run on the client side, in the browser, so you cannot call a PHP function directly. Instead, you need to add a JavaScript function that (as you mentioned) uses AJAX to call a PHP script and retrieve the data. Using jQuery, you can do something like this:

<script type="text/javascript">
function recp(id) {
  $('#myStyle').load('data.php?id=' + id);
}
</script>

<a href="#" onClick="recp('1')" > One   </a>
<a href="#" onClick="recp('2')" > Two   </a>
<a href="#" onClick="recp('3')" > Three </a>

<div id='myStyle'>
</div>

Then you put your PHP code into a separate file: (I've called it data.php in the above example)

<?php
  require ('myConnect.php');     
  $id = $_GET['id'];
  $results = mysql_query("SELECT para FROM content WHERE  para_ID='$id'");   
  if( mysql_num_rows($results) > 0 )
  {
   $row = mysql_fetch_array( $results );
   echo $row['para'];
  }
?>

You use ttk.Frame, bg option does not work for it. You should create style and apply it to the frame.

from tkinter import *
from tkinter.ttk import * 

root = Tk()

s = Style()
s.configure('My.TFrame', background='red')

mail1 = Frame(root, style='My.TFrame')
mail1.place(height=70, width=400, x=83, y=109)
mail1.config()
root.mainloop()

Had several modules complain about patch does not apply. One thing I was missing out was that the branches had become stale. After the git merge master generated the patch files using git diff master BRANCH > file.patch. Going to the vanilla branch was able to apply the patch with git apply file.patch

Once you open your eclipse you can try below

Looks like your application consumes more memory than allocated (Default). I will try two things

1. As suggested by Harmlezz increase your memory allocation to JVM to -Xms2g -Xmx2g (If needed increase it more and try it out)

2. Download eclipse memory analyzer and check for what causing memory leak OR even you can use JConsole to see JVM memory utilization in order to figure out application memory leak issue.

You can edit your second code example to:

Random rn = new Random();
int range = maximum - minimum + 1;
int randomNum =  rn.nextInt(range) + minimum;

I copied the following from Ricardo Tomasi's answer and modified to also create sub-objects that don't yet exist as necessary. It's a little less efficient (more ifs and creating of empty objects), but should be pretty good.

Also, it'll allow us to do Object.prop(obj, 'a.b', false) where we couldn't before. Unfortunately, it still won't let us assign undefined...Not sure how to go about that one yet.

/**
 * Object.prop()
 *
 * Allows dot-notation access to object properties for both getting and setting.
 *
 * @param {Object} obj    The object we're getting from or setting
 * @param {string} prop   The dot-notated string defining the property location
 * @param {mixed}  val    For setting only; the value to set
 */
 Object.prop = function(obj, prop, val){
   var props = prop.split('.'),
       final = props.pop(),
       p;

   for (var i = 0; i < props.length; i++) {
     p = props[i];
     if (typeof obj[p] === 'undefined') {
       // If we're setting
       if (typeof val !== 'undefined') {
         // If we're not at the end of the props, keep adding new empty objects
         if (i != props.length)
           obj[p] = {};
       }
       else
         return undefined;
     }
     obj = obj[p]
   }
   return typeof val !== "undefined" ? (obj[final] = val) : obj[final]
 }

Use getChildCount() and getChildAt(int index).

Example:

LinearLayout ll = …
final int childCount = ll.getChildCount();
for (int i = 0; i < childCount; i++) {
      View v = ll.getChildAt(i);
      // Do something with v.
      // …
}

To tell eclipse to use JDK, you have to follow the below steps.

1. Select the Window menu and then Select Preferences. You can see a dialog box.
2. Then select Java ---> Installed JRE’s
3. Then click Add and select Standard VM then click Next
4. In the JRE home, navigate to the folder you’ve installed the JDK (For example, in my system my JDK was in C:\Program Files\Java\jdk1.8.0_181\ )
5. Now click on Finish.

After completing the above steps, you are done now and eclipse will start using the selected JDK for compilation.

To remove all OIDs from your database tables, you can use this Linux script:

First, login as PostgreSQL superuser:

sudo su postgres

Now run this script, changing YOUR_DATABASE_NAME with you database name:

for tbl in `psql -qAt -c "select schemaname || '.' || tablename from pg_tables WHERE schemaname <> 'pg_catalog' AND schemaname <> 'information_schema';" YOUR_DATABASE_NAME` ; do  psql -c "alter table $tbl SET WITHOUT OIDS" YOUR_DATABASE_NAME ; done

I used this script to remove all my OIDs, since Npgsql 3.0 doesn't work with this, and it isn't important to PostgreSQL anymore.

You can use a shebang file :

script.js

#!/usr/bin/env node
console.log('Hello terminal');

And run it

./script.js

Don't forget to chmod +x script.js

Try setting path to /var/lib/mysql-files/filename.csv (MySQL 8). Determine what files directory is yours by typping SHOW VARIABLES LIKE "secure_file_priv"; in mysql client command line.

See answer about here: (...) --secure-file-priv in MySQL answered in 2015 by vhu user

$query= $this->m_general->get('users' , array('id'=> $id ));
echo $query[''];

is ok ;)

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

You are right the urllib and urllib2 packages have been split into urllib.request , urllib.parse and urllib.error packages in Python 3.x. The latter packages do not exist in Python 2.x

From documentation -

The urllib module has been split into parts and renamed in Python 3 to urllib.request, urllib.parse, and urllib.error.

From urllib2 documentation -

The urllib2 module has been split across several modules in Python 3 named urllib.request and urllib.error.

So I am pretty sure the code you downloaded has been written for Python 3.x , since they are using a library that is only present in Python 3.x .

There is a urllib package in python, but it does not have the request subpackage. Also, lets assume you do lots of work and somehow make request subpackage available in Python 2.x .

There is a very very high probability that you will run into more issues, there is lots of incompatibility between Python 2.x and Python 3.x , in the end you would most probably end up rewriting atleast half the code from github (and most probably reading and understanding the complete code from there).

Even then there may be other bugs arising from the fact that some of the implementation details changed between Python 2.x to Python 3.x (As an example - list comprehension got its own namespace in Python 3.x)

You are better off trying to download and use Python 3 , than trying to make code written for Python 3.x compatible with Python 2.x

Ryley's answer is great, but I have text within the element. In order to rotate the text along with everything else, I used the border-spacing property instead of text-indent.

Also, to clarify a bit, in the element's style, set your initial value:

#foo {
    border-spacing: 0px;
}

Then in the animate chunk, your final value:

$('#foo').animate({  borderSpacing: -90 }, {
    step: function(now,fx) {
      $(this).css('transform','rotate('+now+'deg)');  
    },
    duration:'slow'
},'linear');

In my case, it rotates 90 degrees counter-clockwise.

Here is the live demo.

Don't forget you can also use pure JavaScript to deal with this situation, using:

window.scrollTo(x-coord, y-coord);

Yarn supports this feature:

# .yarnrc file in project root
--modules-folder /node_modules

But your experience can vary depending on which packages you use. I'm not sure you'd want to go into that rabbit hole.

Have you tried:

ifconfig 10:35978f0 down

As the physical interface is 10 and the virtual aspect is after the colon :.

See also https://www.cyberciti.biz/faq/linux-command-to-remove-virtual-interfaces-or-network-aliases/

This should work. You may save the following in a batch file:

TASKKILL /F /IM chrome.exe
start chrome.exe --args --disable-web-security
pause

Update (2017-08-04)

As of (at least) macOS 10.12.6 (Sierra) this method seems to have stopped working for Apache httpd (for both the system and the user option of launchctl config). Other programs do not seem to be affected. It is conceivable that this is a bug in httpd.

Original answer

This concerns OS X 10.10+ (10.11+ specifically due to rootless mode where /usr/bin is no longer writeable).

I've read in multiple places that using launchctl setenv PATH <new path> to set the PATH variable does not work due to a bug in OS X (which seems true from personal experience). I found that there's another way the PATH can be set for applications not launched from the shell:

sudo launchctl config user path <new path>

This option is documented in the launchctl man page:

config system | user parameter value

Sets persistent configuration information for launchd(8) domains. Only the system domain and user domains may be configured. The location of the persistent storage is an implementation detail, and changes to that storage should only be made through this subcommand. A reboot is required for changes made through this subcommand to take effect.

[...]

path

Sets the PATH environment variable for all services within the target domain to the string value. The string value should conform to the format outlined for the PATH environment variable in environ(7). Note that if a service specifies its own PATH, the service-specific environment variable will take precedence.

NOTE: This facility cannot be used to set general environment variables for all services within the domain. It is intentionally scoped to the PATH environment vari- able and nothing else for security reasons.

I have confirmed this to work with a GUI application started from Finder (which uses getenv to get PATH). Note that you only have to do this once and the change will be persistent through reboots.

I tried doing something similar, which took me a lot of time before I could figure out the collect() function. So you can have something this way:

collect($items)->sum('amount');

This will give you the sum total of all the items.

If it is a GET service, then you need to use it with a GET method, not a POST method. Your problem is a type mismatch. A different example of type mismatch (to put severity into perspective) is trying to assign a string to an integer variable.

Container widths will drop down to 940 pixels for viewports less than 992 pixels. If you really don’t want containers larger than 940 pixels wide, then go to the Bootstrap customize page, and set @container-lg-desktop to either @container-desktop or hard-coded 940px.

You have to do write in the same loop as read.

I think what you are trying to do is probably counter-productive.

Making it easy for people to rate apps is generally a good idea, as most people who bother do so because they like the app. It is rumoured that the number of ratings affects your market rating (although I see little evidence of this). Hassling users into rating - through nag screens - is likely to cause people to clear the nag through leaving a bad rating.

Adding the capability to directly rate an app has caused a slight decrease in the numerical ratings for my free version, and a slight increase in my paid app. For the free app, my 4 star ratings increased more than my 5 star ratings, as people who thought my app was good but not great started to rate it as well. Change was about -0.2. For the paid, change was about +0.1. I should remove it from the free version, except I like getting lots of comments.

I put my rating button into a settings (preference) screen, where it does not affect normal operation. It still increased my rating rate by a factor of 4 or 5. I have no doubt that if I tried nagging my users into making a rating, I would get lots of users giving me bad ratings as a protest.

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    die("Database selection failed: " . mysqli_error($connection));
}

You got the order of the arguments to mysqli_select_db() backwards. And mysqli_error() requires you to provide a connection argument. mysqli_XXX is not like mysql_XXX, these arguments are no longer optional.

Note also that with mysqli you can specify the DB in mysqli_connect():

$connection = mysqli_connect(DB_SERVER, DB_USER, DB_PASS, DB_NAME);
if (!$connection) {
  die("Database connection failed: " . mysqli_connect_error();
}

You must use mysqli_connect_error(), not mysqli_error(), to get the error from mysqli_connect(), since the latter requires you to supply a valid connection.

Ex:-

var value="Data-123";
var removeData=value.replace("Data-","");
alert(removeData);

Hopefully this will work for you.

I = imread('peppers.png');
H = fspecial('average', [5 5]);
I = imfilter(I, H);
imshow(I)

Note that filters can be applied to intensity images (2D matrices) using filter2, while on multi-dimensional images (RGB images or 3D matrices) imfilter is used.

Also on Intel processors, imfilter can use the Intel Integrated Performance Primitives (IPP) library to accelerate execution.

An example with a little less stringified html:

var container = $('#my-container'),
  table = $('<table>');

users.forEach(function(user) {
  var tr = $('<tr>');
  ['ID', 'Name', 'Address'].forEach(function(attr) {
    tr.append('<td>' + user[attr] + '</td>');
  });
  table.append(tr);
});

container.append(table);

According to the protocol spec v76 (which is the version that browser with current support implement):

To close the connection cleanly, a frame consisting of just a 0xFF byte followed by a 0x00 byte is sent from one peer to ask that the other peer close the connection.

If you are writing a server, you should make sure to send a close frame when the server closes a client connection. The normal TCP socket close method can sometimes be slow and cause applications to think the connection is still open even when it's not.

The browser should really do this for you when you close or reload the page. However, you can make sure a close frame is sent by doing capturing the beforeunload event:

window.onbeforeunload = function() {
    websocket.onclose = function () {}; // disable onclose handler first
    websocket.close();
};

I'm not sure how you can be getting an onclose event after the page is refreshed. The websocket object (with the onclose handler) will no longer exist once the page reloads. If you are immediately trying to establish a WebSocket connection on your page as the page loads, then you may be running into an issue where the server is refusing a new connection so soon after the old one has disconnected (or the browser isn't ready to make connections at the point you are trying to connect) and you are getting an onclose event for the new websocket object.

You're looking for the document.documentElement.scrollTop property.

essentially the shadow is the box shape just offset behind the actual box. in order to hide portions of the shadow, you need to create additional divs and set their z-index above the shadowed box so that the shadow is not visible.

If you'd like to have extremely specific control over your shadows, build them as images and created container divs with the right amount of padding and margins.. then use the png fix to make sure the shadows render properly in all browsers

If what you want is to show with an alert() the content of an array of objects, i recomend you to define in the object the method toString() so with a simple alert(MyArray); the full content of the array will be shown in the alert.

Here is an example:

//-------------------------------------------------------------------
// Defininf the Point object
function Point(CoordenadaX, CoordenadaY) {
    // Sets the point coordinates depending on the parameters defined
    switch (arguments.length) {
        case 0:
            this.x = null;
            this.y = null;
            break;
        case 1:
            this.x = CoordenadaX;
            this.y = null;
            break;
        case 2:
            this.x = CoordenadaX;
            this.y = CoordenadaY;
            break;
    }
    // This adds the toString Method to the point object so the 
    // point can be printed using alert();
    this.toString = function() {
        return " (" + this.x + "," + this.y + ") ";
    };
 }

Then if you have an array of points:

var MyArray = [];
MyArray.push ( new Point(5,6) );
MyArray.push ( new Point(7,9) );

You can print simply calling:

alert(MyArray);

Hope this helps!

As tangens said, the size of an array is fixed. But you have to instantiate it first, else it will be only a null reference.

String[] where = new String[10];

This array can contain only 10 elements. So you can append a value only 10 times. In your code you're accessing a null reference. That's why it doesnt work. In order to have a dynamically growing collection, use the ArrayList.

In your Spring @Configuration class which extends WebMvcConfigurerAdapter override the method configureMessageConverters, for instance:

@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {

    // http
    HttpMessageConverter converter = new StringHttpMessageConverter();
    converters.add(converter);
    logger.info("HttpMessageConverter added");

    // string
    converter = new FormHttpMessageConverter();
    converters.add(converter);
    logger.info("FormHttpMessageConverter added");

    // json
    converter = new MappingJackson2HttpMessageConverter();
    converters.add(converter);
    logger.info("MappingJackson2HttpMessageConverter added");

}

And the error will be gone.

Probable cause that remount fails is you are not running adb as root.

Shell Script should be as follow.

# Script to mount Android Device as read/write.
# List the Devices.
adb devices;

# Run adb as root (Needs root access).
adb root;

# Since you're running as root su is not required
adb shell mount -o rw,remount /;

If this fails, you could try the below:

# List the Devices.
adb devices;

# Run adb as root
adb root;

adb remount;
adb shell su -c "mount -o rw,remount /";

To find which user you are:

$ adb shell whoami

This question comes in top of Google search when you find "golang current time format" so, for all the people that want to use another format, remember that you can always call to:

t := time.Now()

t.Year()

t.Month()

t.Day()

t.Hour()

t.Minute()

t.Second()

For example, to get current date time as "YYYY-MM-DDTHH:MM:SS" (for example 2019-01-22T12:40:55) you can use these methods with fmt.Sprintf:

t := time.Now()
formatted := fmt.Sprintf("%d-%02d-%02dT%02d:%02d:%02d",
        t.Year(), t.Month(), t.Day(),
        t.Hour(), t.Minute(), t.Second())

As always, remember that docs are the best source of learning: https://golang.org/pkg/time/

I see that many answers here solve the problem for a specific situation.

For my situation I continually found that the IDE would automatically format JavaScript code within an ASP page.

To disable, I unchecked this box:

In addition, I found it very helpful to use the search query in the toolbar (CTRL+Q) and just search for the text format on paste. As you can see with the scroll bar, there are quite a few options to check!

I've resolved the issue. It was due to the SQL browser service.

Solution to such problem is one among below -

• Check the spelling of the SQL Server instance name that is specified in the connection string.

• Use the SQL Server Surface Area Configuration tool to enable SQL Server to accept remote connections over the TCP or named pipes protocols. For more information about the SQL Server Surface Area Configuration Tool, see Surface Area Configuration for Services and Connections.

• Make sure that you have configured the firewall on the server instance of SQL Server to open ports for SQL Server and the SQL Server Browser port (UDP 1434).

• Make sure that the SQL Server Browser service is started on the server.

You can retrieve all the keys of the $_POST array using array_keys(), then construct an email messages with the values of those keys.

var_dump($_POST) will also dump information about all of the information in $_POST for you.

.outerdiv {
    margin-left: auto;
    margin-right: auto;
    display: table;
}

Doesn't work in internet explorer 7... but who cares ?

If CURLOPT_FAILONERROR is false, http errors will not trigger curl errors.

<?php
if (@$_GET['curl']=="yes") {
  header('HTTP/1.1 503 Service Temporarily Unavailable');
} else {
  $ch=curl_init($url = "http://".$_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF']."?curl=yes");
  curl_setopt($ch, CURLOPT_FAILONERROR, true);
  $response=curl_exec($ch);
  $http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  $curl_errno= curl_errno($ch);
  if ($http_status==503)
    echo "HTTP Status == 503 <br/>";
  echo "Curl Errno returned $curl_errno <br/>";
}

Use fmod() from <cmath>. If you do not want to include the C header file:

template<typename T, typename U>
constexpr double dmod (T x, U mod)
{
    return !mod ? x : x - mod * static_cast<long long>(x / mod);
}

//Usage:
double z = dmod<double, unsigned int>(14.3, 4);
double z = dmod<long, float>(14, 4.6);
//This also works:
double z = dmod(14.7, 0.3);
double z = dmod(14.7, 0);
double z = dmod(0, 0.3f);
double z = dmod(myFirstVariable, someOtherVariable);

Yes, you can assign one instance of a struct to another using a simple assignment statement.

• In the case of non-pointer or non pointer containing struct members, assignment means copy.

• In the case of pointer struct members, assignment means pointer will point to the same address of the other pointer.

Let us see this first hand:

#include <stdio.h>

struct Test{
    int foo;
    char *bar;
};

int main(){
    struct Test t1;
    struct Test t2;
    t1.foo = 1;
    t1.bar = malloc(100 * sizeof(char));
    strcpy(t1.bar, "t1 bar value");
    t2.foo = 2;
    t2.bar = malloc(100 * sizeof(char));
    strcpy(t2.bar, "t2 bar value");
    printf("t2 foo and bar before copy: %d %s\n", t2.foo, t2.bar);
    t2 = t1;// <---- ASSIGNMENT
    printf("t2 foo and bar after copy: %d %s\n", t2.foo, t2.bar);
    //The following 3 lines of code demonstrate that foo is deep copied and bar is shallow copied
    strcpy(t1.bar, "t1 bar value changed");
    t1.foo = 3;
    printf("t2 foo and bar after t1 is altered: %d %s\n", t2.foo, t2.bar);
    return 0;
}

Solution: Edit and save the file!

From VisualStudio go to the View and expand to see it's resx file

Right-click menu select OpenWith... XML (Text) Editor.

Just add a space at the end and save.

You can try it this way:

/* Get the data into a temp table */
SELECT * INTO #TempTable
FROM YourTable
/* Drop the columns that are not needed */
ALTER TABLE #TempTable
DROP COLUMN ColumnToDrop
/* Get results and drop temp table */
SELECT * FROM #TempTable
DROP TABLE #TempTable

Imho this is a flaw in many c compilers. I know for a fact that the compilers i worked with do not store a "static const"variable at an adress but replace the use in the code by the very constant. This can be verified as you will get the same checksum for the produced code when you use a preprocessors #define directive and when you use a static const variable.

Either way you should use static const variables instead of #defines whenever possible as the static const is type safe.

void FindMax()
{
    int lessonNum;

    System.out.print("Enter your lesson numbers : ");
    lessonNum = input.nextInt();
    int[] numbers = new int[lessonNum];
    for (int i = 0; i < numbers.length; i++)
    {
        System.out.print("Please enter " + (i + 1) + " number : ");
        numbers[i] = input.nextInt();
    }
    double max = numbers[0];
    for (int i = 1; i < numbers.length; i++)
    {
        if (numbers[i] > max)
        {
            max = numbers[i];
        }
    }
    System.out.println("Maximum number is : " + max);
}

This may be helpful while searching keys present in nested objects and nested arrays. And this is a generic solution to all cases.

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

public class MyClass
{
    public static Object finalresult = null;
    public static void main(String args[]) throws JSONException
    {
        System.out.println(myfunction(myjsonstring,key));
    }

    public static Object myfunction(JSONObject x,String y) throws JSONException
    {
        JSONArray keys =  x.names();
        for(int i=0;i<keys.length();i++)
        {
            if(finalresult!=null)
            {
                return finalresult;                     //To kill the recursion
            }

            String current_key = keys.get(i).toString();

            if(current_key.equals(y))
            {
                finalresult=x.get(current_key);
                return finalresult;
            }

            if(x.get(current_key).getClass().getName().equals("org.json.JSONObject"))
            {
                myfunction((JSONObject) x.get(current_key),y);
            }
            else if(x.get(current_key).getClass().getName().equals("org.json.JSONArray"))
            {
                for(int j=0;j<((JSONArray) x.get(current_key)).length();j++)
                {
                    if(((JSONArray) x.get(current_key)).get(j).getClass().getName().equals("org.json.JSONObject"))
                    {
                        myfunction((JSONObject)((JSONArray) x.get(current_key)).get(j),y);
                    }
                }
            }
        }
        return null;
    }
}

Possibilities:

1. "key":"value"
2. "key":{Object}
3. "key":[Array]

Logic :

• I check whether the current key and search key are the same, if so I return the value of that key.
• If it is an object, I send the value recursively to the same function.
• If it is an array, I check whether it contains an object, if so I recursively pass the value to the same function.

You can just say

callback();

Alternately you can use the call method if you want to adjust the value of this within the callback.

callback.call( newValueForThis);

Inside the function this would be whatever newValueForThis is.

This is so called file local variables, that are understood by Emacs and set correspondingly. See corresponding section in Emacs manual - you can define them either in header or in footer of file

I presume you meant false instead of 'false'

Also, [disabled] is expecting a Boolean. You should avoid returning a null.

If Table variable has large data, then instead of table variable(@table) create temp table (#table).table variable doesn't allow to create index after insert.

 CREATE TABLE #Table(C1 int,       
  C2 NVarchar(100) , C3 varchar(100)
  UNIQUE CLUSTERED (c1) 
 ); 

1. Create table with unique clustered index

2. Insert data into Temp "#Table" table

3. Create non clustered indexes.

    CREATE NONCLUSTERED INDEX IX1  ON #Table (C2,C3);
   

If you know which column to search against, you can use array_search() and array_column():

$userdb = Array
(
    (0) => Array
        (
            ('uid') => '100',
            ('name') => 'Sandra Shush',
            ('url') => 'urlof100'
        ),

    (1) => Array
        (
            ('uid') => '5465',
            ('name') => 'Stefanie Mcmohn',
            ('url') => 'urlof5465'
        ),

    (2) => Array
        (
            ('uid') => '40489',
            ('name') => 'Michael',
            ('url') => 'urlof40489'
        )
);

if(array_search('urlof5465', array_column($userdb, 'url')) !== false) {
    echo 'value is in multidim array';
}
else {
    echo 'value is not in multidim array';
}

This idea is in the comments section for array_search() on the PHP manual;

In your test code your are trying to pass App to the spyOn function, but spyOn will only work with objects, not classes. Generally you need to use one of two approaches here:

1) Where the click handler calls a function passed as a prop, e.g.

class App extends Component {

  myClickFunc = () => {
      console.log('clickity clickcty');
      this.props.someCallback();
  }
  render() {
    return (
      <div className="App">
        <div className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro" onClick={this.myClickFunc}>
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

You can now pass in a spy function as a prop to the component, and assert that it is called:

describe('my sweet test', () => {
 it('clicks it', () => {
    const spy = jest.fn();
    const app = shallow(<App someCallback={spy} />)
    const p = app.find('.App-intro')
    p.simulate('click')
    expect(spy).toHaveBeenCalled()
 })
})

2) Where the click handler sets some state on the component, e.g.

class App extends Component {
  state = {
      aProperty: 'first'
  }

  myClickFunc = () => {
      console.log('clickity clickcty');
      this.setState({
          aProperty: 'second'
      });
  }
  render() {
    return (
      <div className="App">
        <div className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro" onClick={this.myClickFunc}>
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

You can now make assertions about the state of the component, i.e.

describe('my sweet test', () => {
 it('clicks it', () => {
    const app = shallow(<App />)
    const p = app.find('.App-intro')
    p.simulate('click')
    expect(app.state('aProperty')).toEqual('second');
 })
})

Looking at http.Request you can find the following member variables:

// HTTP defines that header names are case-insensitive.
// The request parser implements this by canonicalizing the
// name, making the first character and any characters
// following a hyphen uppercase and the rest lowercase.
//
// For client requests certain headers are automatically
// added and may override values in Header.
//
// See the documentation for the Request.Write method.
Header Header

// RemoteAddr allows HTTP servers and other software to record
// the network address that sent the request, usually for
// logging. This field is not filled in by ReadRequest and
// has no defined format. The HTTP server in this package
// sets RemoteAddr to an "IP:port" address before invoking a
// handler.
// This field is ignored by the HTTP client.
RemoteAddr string

You can use RemoteAddr to get the remote client's IP address and port (the format is "IP:port"), which is the address of the original requestor or the last proxy (for example a load balancer which lives in front of your server).

This is all you have for sure.

Then you can investigate the headers, which are case-insensitive (per documentation above), meaning all of your examples will work and yield the same result:

req.Header.Get("X-Forwarded-For") // capitalisation
req.Header.Get("x-forwarded-for") // doesn't
req.Header.Get("X-FORWARDED-FOR") // matter

This is because internally http.Header.Get will normalise the key for you. (If you want to access header map directly, and not through Get, you would need to use http.CanonicalHeaderKey first.)

Finally, "X-Forwarded-For" is probably the field you want to take a look at in order to grab more information about client's IP. This greatly depends on the HTTP software used on the remote side though, as client can put anything in there if it wishes to. Also, note the expected format of this field is the comma+space separated list of IP addresses. You will need to parse it a little bit to get a single IP of your choice (probably the first one in the list), for example:

// Assuming format is as expected
ips := strings.Split("10.0.0.1, 10.0.0.2, 10.0.0.3", ", ")
for _, ip := range ips {
    fmt.Println(ip)
}

will produce:

10.0.0.1
10.0.0.2
10.0.0.3

We can calculate using mid point of line formula,

centre (x,y) =  new Point((boundRect.tl().x+boundRect.br().x)/2,(boundRect.tl().y+boundRect.br().y)/2)

I found that we can use extend() to implement the function of copy()

a=['help', 'copyright', 'credits', 'license']
b = []
b.extend(a)
b.append("XYZ") 

Stepping on the answer of @Brian Cline I thought I might give my 5 cents

See keyboard hooks; this is more generalized-- if you want specific keyboard interactions and not just using KeyboardInterrupt.

Also, in general (depending on your use) I think having the Ctrl-C option still available to kill your script makes sense.

i created a custom collection view layout here that supports:

• paging one cell at a time
• paging 2+ cells at a time depending on swipe velocity
• horizontal or vertical directions

it's as easy as:

let layout = PagingCollectionViewLayout()

layout.itemSize = 
layout.minimumLineSpacing = 
layout.scrollDirection = 

you can just add PagingCollectionViewLayout.swift to your project

or

add pod 'PagingCollectionViewLayout' to your podfile

I have 2 servers setup on docker, reverse proxy & web server. This error started happening for all my websites all of a sudden after 1 year. When setting up earlier, I generated a self signed certificate on the web server.

So, I had to generate the SSL certificate again and it started working...

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ssl.key -out ssl.crt

The easiest way of getting UTC time in a conventional format is as follows:

new Date().toISOString()
"2016-06-03T23:15:33.008Z"

In simple words:

The next iteration of the loop takes double the time the current one took --> n^2

The next iteration of the loop takes same the time the current one is going to take --> n

The next iteration of the loop takes half the time the current one is going to take --> log₂(n)

The next iteration of the loop takes 1/3rd the time the current one is going to take --> log₃(n)

The next iteration of the loop takes 1/4th the time the current one is going to take --> log₄(n)

When it comes to Asymptotic analysis, we just call log(n) which can be basically any base as shown above. But since we computer scientists use binary trees more than other types of trees, we end up with log₂(n) most of the times which we just term log(n).

At the moment you're calling ToUniversalTime() - just get rid of that:

private long ConvertToTimestamp(DateTime value)
{
    long epoch = (value.Ticks - 621355968000000000) / 10000000;
    return epoch;
}

Alternatively, and rather more readably IMO:

private static readonly DateTime Epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
...

private static long ConvertToTimestamp(DateTime value)
{
    TimeSpan elapsedTime = value - Epoch;
    return (long) elapsedTime.TotalSeconds;
}

EDIT: As noted in the comments, the Kind of the DateTime you pass in isn't taken into account when you perform subtraction. You should really pass in a value with a Kind of Utc for this to work. Unfortunately, DateTime is a bit broken in this respect - see my blog post (a rant about DateTime) for more details.

You might want to use my Noda Time date/time API instead which makes everything rather clearer, IMO.

You need to set Div2 to Div1's innerHTML. Also, JavaScript is case sensitive - in your HTML, the id Div2 is DIV2. Also, you should use document, not Document:

var MyDiv1 = document.getElementById('DIV1');
var MyDiv2 = document.getElementById('DIV2');
MyDiv2.innerHTML = MyDiv1.innerHTML; 

Here is a JSFiddle: http://jsfiddle.net/gFN6r/.

You can make a json object like:

globalVariable={example_attribute:"SomeValue"}; 

in fileA.js

And access it from fileB.js like: globalVariable.example_attribute

Pull multiple files using regex:

Create pullFiles.sh:

#!/bin/bash
HOST_DIR=<pull-to>
DEVICE_DIR=/sdcard/<pull-from>
EXTENSION=".jpg"

for file in $(adb shell ls $DEVICE_DIR | grep $EXTENSION'$')
do
    file=$(echo -e $file | tr -d "\r\n"); # EOL fix
    adb pull $DEVICE_DIR/$file $HOST_DIR/$file;
done

Run it:

Make it executable: chmod +x pullFiles.sh

Run it: ./pullFiles.sh

Notes:

• as is, won't work when filenames have spaces
• includes a fix for end-of-line (EOL) on Android, which is a "\r\n"

A lot of SVN repos are "simply" HTTP sites, so you might consider looking at some off the shelf "web crawling" search app that you can point at the SVN root and it will give you basic functionality. Updating it will probably be a bit of a trick, perhaps some SVN check in hackery can tickle the index to discard or reindex changes as you go.

Just thinking out loud.

The solution is to change the DropDownStyle property to DropDownList. It will help.

Install Proxifier in your host computer. Setup proxifier to use your proxy. You don't need to do anything else. You will be fine. Proxifier traps the calls from the system (including the android emulator) and route it through the configured proxy.

Do not use communicate(input=""). It writes input to the process, closes its stdin and then reads all output.

Do it like this:

p=subprocess.Popen(["python","1st.py"],stdin=PIPE,stdout=PIPE)

# get output from process "Something to print"
one_line_output = p.stdout.readline()

# write 'a line\n' to the process
p.stdin.write('a line\n')

# get output from process "not time to break"
one_line_output = p.stdout.readline() 

# write "n\n" to that process for if r=='n':
p.stdin.write('n\n') 

# read the last output from the process  "Exiting"
one_line_output = p.stdout.readline()

What you would do to remove the error:

all_the_process_will_tell_you = p.communicate('all you will ever say to this process\nn\n')[0]

But since communicate closes the stdout and stdin and stderr, you can not read or write after you called communicate.

for centos, just zlib didn't solve the problem.I did sudo yum install zlib-devel.i686

Assuming your int array is sorted, i would do...

int count = 0, occur = 0, high = 0, a;

for (a = 1; a < n.length; a++) {
    if (n[a - 1] == n[a]) {
       count++;
       if (count > occur) {
           occur = count;
           high = n[a];
       }
     } else {
        count = 0;
     }
}
System.out.println("highest occurence = " + high);

Here is some help for 2Tier and 3Tier difference, please refer below.

ANSWER:
1. 2Tier is Client server architecture and 3Tier is Client, Server and Database architecture.
2. 3Tier has a Middle stage to communicate client to server, Where as in 2Tier client directly get communication to server.
3. 3Tier is like a MVC, But having difference in topologies
4. 3Tier is linear means in that request flow is Client>>>Middle Layer(SErver application) >>>Databse server and Response is reverse.
While in 2Tier it a Triangular View >>Controller>>Model
5. 3Tier is like Website while web browser is Client application(middle layer), and ASP/PHP language code is server application.

For forms, use the [FromForm] attribute instead of the [FromBody] attribute.

The below controller works with ASP.NET Core 1.1:

public class MyController : Controller
{
    [HttpPost]
    public async Task<IActionResult> Submit([FromForm] MyModel model)
    {
        //...
    }
}

Note: [FromXxx] is required if your controller is annotated with [ApiController]. For normal view controllers it can be omitted.

Either document.getElementById('i1'), document.getElementById('i2'), or document.getElementsByName("username")[0] is returning no element. Check, that all elements exist.

Did you try using t.Text?

Isodate seems to have the most complete support.

If you have problems with accessing to the path, maybe you need to put this:

$root = $_SERVER['DOCUMENT_ROOT'];
$path = "/cv/"; 

// Open the folder
 $dir_handle = @opendir($root . $path) or die("Unable to open $path");

The tricks above did not help me, as the repo was larger than the max push size allowed at github. What did work was a recommendation from https://github.com/git-lfs/git-lfs/issues/3758 which suggested pushing a bit at a time:

If your branch has a long history, you can try pushing a smaller number of commits at a time (say, 2000) with something like this:

git rev-list --reverse master | ruby -ne 'i ||= 0; i += 1; puts $_ if i % 2000 == 0' | xargs -I{} git push origin +{}:refs/heads/master

That will walk through the history of master, pushing objects 2000 at a time. (You can, of course, substitute a different branch in both places if you like.) When that's done, you should be able to push master one final time, and things should be up to date. If 2000 is too many and you hit the problem again, you can adjust the number so it's smaller.

I also had the same problem. Then I installed the zlib, still the problem remained the same. Then I added the following lines in my .bashrc and it worked. You should replace the path with your zlib installation path. (I didn't have root privileges).

export PATH =$PATH:$HOME/Softwares/library/Zlib/zlib-1.2.11/

For anyone looking for a Xamarin implementation (since events are done differently in C#), I simply created this NavClickHandler class as follows:

public class NavClickHandler : Java.Lang.Object, View.IOnClickListener
{
    private Activity mActivity;
    public NavClickHandler(Activity activity)
    {
        this.mActivity = activity;
    }
    public void OnClick(View v)
    {
        DrawerLayout drawer = (DrawerLayout)mActivity.FindViewById(Resource.Id.drawer_layout);
        if (drawer.IsDrawerOpen(GravityCompat.Start))
        {
            drawer.CloseDrawer(GravityCompat.Start);
        }
        else
        {
            drawer.OpenDrawer(GravityCompat.Start);
        }
    }
}

Then, assigned a custom hamburger menu button like this:

        SupportActionBar.SetDisplayHomeAsUpEnabled(true);
        SupportActionBar.SetDefaultDisplayHomeAsUpEnabled(false);
        this.drawerToggle.DrawerIndicatorEnabled = false;
        this.drawerToggle.SetHomeAsUpIndicator(Resource.Drawable.MenuButton);

And finally, assigned the drawer menu toggler a ToolbarNavigationClickListener of the class type I created earlier:

        this.drawerToggle.ToolbarNavigationClickListener = new NavClickHandler(this);

And then you've got a custom menu button, with click events handled.

/\S/.test(string) returns true if and only if there's a non-space character in string. Tab and newline count as spaces.

Use the find command.

Assuming you're using Bash 4.2+, use -printf '%T+ %p\n' for file timestamp value.

find $DIR -type f -printf '%T+ %p\n' | sort -r | head -n 1 | cut -d' ' -f2

Example:

find ~/Downloads -type f -printf '%T+ %p\n' | sort -r | head -n 1 | cut -d' ' -f2

For a more useful script, see the find-latest script here: https://github.com/l3x/helpers

This can be done in in 3 lines of code:

// grab the window frame and adjust it for orientation
UIView *rootView = [[[UIApplication sharedApplication] keyWindow] 
                                   rootViewController].view;
CGRect originalFrame = [[UIScreen mainScreen] bounds];
CGRect adjustedFrame = [rootView convertRect:originalFrame fromView:nil];

Use substr with parameter -1:

"linto.yahoo.com.".substr(-1);

equals "."

Note:

To extract characters from the end of the string, use a negative start number (This does not work in IE 8 and earlier).

try this:

download firefox, add the plugin "firebug" and "firepath"; after install them go to your webpage, start firebug and find the xpath of the element, it unique in the page so you can't make any mistake.

See picture:

browser.find_element_by_xpath('just copy and paste the Xpath').click()

I use Pixlr - an online photo editor, it has great filters and user friendly interface.

Update
From v0.24.0 onwards, you can merge on DataFrame and Series as long as the Series is named.

df.merge(s.rename('new'), left_index=True, right_index=True)
# If series is already named,
# df.merge(s, left_index=True, right_index=True)

Nowadays, you can simply convert the Series to a DataFrame with to_frame(). So (if joining on index):

df.merge(s.to_frame(), left_index=True, right_index=True)

As others pointed out, the only difference is that require throws a fatal error, and include - a catchable warning. As for which one to use, my advice is to stick to include. Why? because you can catch a warning and produce a meaningful feedback to end users. Consider

  // Example 1.
  // users see a standard php error message or a blank screen
  // depending on your display_errors setting
  require 'not_there'; 


  // Example 2.
  // users see a meaningful error message
  try {
      include 'not_there';
  } catch(Exception $e) {
     echo "something strange happened!";
  }

NB: for example 2 to work you need to install an errors-to-exceptions handler, as described here http://www.php.net/manual/en/class.errorexception.php

  function exception_error_handler($errno, $errstr, $errfile, $errline ) {
     throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
  }
  set_error_handler("exception_error_handler");   

input file element:

<input type="file" id="fileinput" />

get file :

var myFile = $('#fileinput').prop('files');

Using description as many of these answers suggest is the wrong approach - even if you get it to work, it will break in iOS 13+.

Instead you should ensure you use the actual binary data, not simply a description of it. Andrey Gagan addressed the Objective C solution quite well, but fortunately it's much simpler in swift:

Swift 4.2 works in iOS 13+

// credit to NSHipster (see link above)
// format specifier produces a zero-padded, 2-digit hexadecimal representation
let deviceTokenString = deviceToken.map { String(format: "%02x", $0) }.joined()

The problem with all of these answers for me was they weren't responsive. I had to have a fixed height for a parent div which i didn't want. I also didn't want to spend a ton of time dinking around with media queries. If you are using angular, you can use bootstraps tabset and it will do all of the hard work for you. You'll be able to scroll the inner content and it will be responsive. When you setup the tab, do it like this: $scope.tab = { title: '', url: '', theclass: '', ative: true }; ... the point is, you don't want a title or image icon. then hide the outline of the tab in cs like this:

.nav-tabs {
   border-bottom:none; 
} 

and also this .nav-tabs > li.active > a, .nav-tabs > li.active > a:hover, .nav-tabs > li.active > a:focus {border:none;} and finally to remove the invisible tab that you can still click on if you don't implement this: .nav > li > a {padding:0px;margin:0px;}

Use following codes to read the file

import java.io.File;
import java.util.Scanner;

public class ReadFile {

    public static void main(String[] args) {

        try {
            System.out.print("Enter the file name with extension : ");

            Scanner input = new Scanner(System.in);

            File file = new File(input.nextLine());

            input = new Scanner(file);


            while (input.hasNextLine()) {
                String line = input.nextLine();
                System.out.println(line);
            }
            input.close();

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

}

-> This application is printing the file content line by line

In a sense you're right, although anything lower than 2^8 characters will still register as a byte of data.

If you account for the base character that leaves anything with a VARCHAR < 255 as consuming the same amount of space.

255 is a good baseline definition unless you particularly wish to curtail excessive input.

A nice way to do this is using Apache commons IOUtils to copy the InputStream into a StringWriter... something like

StringWriter writer = new StringWriter();
IOUtils.copy(inputStream, writer, encoding);
String theString = writer.toString();

or even

// NB: does not close inputStream, you'll have to use try-with-resources for that
String theString = IOUtils.toString(inputStream, encoding); 

Alternatively, you could use ByteArrayOutputStream if you don't want to mix your Streams and Writers

char ch;
FILE *f = fopen("file.txt", "r");

if(fscanf(f,"%c",&ch)==EOF)
{
    printf("File is Empty");
}
fclose(f);

Relying on column order is generally a bad idea in SQL. SQL is based on Relational theory where order is never guaranteed - by design. You should treat all your columns and rows as having no order and then change your queries to provide the correct results:

For Columns:

• Try not to use SELECT *, but instead specify the order of columns in the select list as in: SELECT Member_ID, MemberName, MemberAddress from TableName. This will guarantee order and will ease maintenance if columns get added.

For Rows:

• Row order in your result set is only guaranteed if you specify the ORDER BY clause.
• If no ORDER BY clause is specified the result set may differ as the Query Plan might differ or the database pages might have changed.

Hope this helps...

It took me a while to create a solution to this problem I was happy with:

Problem:

• An SVG sprite of icons - say 80px x 3200px

• We want to scale each use of them in content selectors (:before/:after) in various places over various sizes without re-defining the co-ords of each sprite based on the size used.

So this solution allows you to use the same sprite co-ords in a <button> as a <menuitem> whilst still scaling it.

[data-command]::before {
    content: '';
    position: absolute;
    background-image: url("images/sprite.svgz");
    background-repeat: no-repeat;
    background-size: cover;
}

button[data-command]::before {
  width: 32px;
  height: 32px;
}

menuitem[data-command]::before {
  width: 24px;
  height: 24px;
}

[data-command="cancel"]::before {
  background-position: 0% 35%;
}

[data-command="logoff"]::before {
  background-position: 0% 37.5%;
}

By using percentages (to 2 decimal places) in background-position rather than background-size as suggested by others here, you can scale the same icon declaration to any size, without needing to redeclare it.

The position-y percentage is the original sprite height/icon height as a % - in our case here 80px*100/3200px == each sprite is represented by a y-position of 2.5%.

If you have hover/mouseover states you can double the width of the sprite and specify in the position-x coordinate.

The disadvantage of this approach is that adding more icons at a later date will change the sprite height and so y-position %, but if you don't do that then your sprite co-ordinates will need change for each scaled resolution you require.

I don't think this is possible with AD. The distinguishedName attribute is the only thing I know of that contains the OU piece on which you're trying to search, so you'd need a wildcard to get results for objects under those OUs. Unfortunately, the wildcard character isn't supported on DNs.

If at all possible, I'd really look at doing this in 2 queries using OU=Staff... and OU=Vendors... as the base DNs.

Yes, open a postscript() device with a filename ending in .eps, do your plot(s) and call dev.off().

What you could do is, create the "function" as another template file and then include that file passing the parameters to it.

Inside index.html

<h3> Latest Songs </h3>
{% include "song_player_list.html" with songs=latest_songs %}

Inside song_player_list.html

<ul>
{%  for song in songs %}
<li>
<div id='songtile'>
<a href='/songs/download/{{song.id}}/'><i class='fa fa-cloud-download'></i>&nbsp;Download</a>

</div>
</li>
{% endfor %}
</ul>

With text files, maybe the EOF is -1 when using BufferReader.read(), char by char. I made a test with BufferReader.readLine()!=null and it worked properly.

well the only thing that will work is

python -m pip install pip==

you can and should run it under IDE terminal (mine was pycharm)

This seems to be the problem when you use OkHttp along with Retrofit, so either you can remove OkHttp or use code below to get error body:

if (!response.isSuccessful()) {
 InputStream i = response.errorBody().byteStream();
 BufferedReader r = new BufferedReader(new InputStreamReader(i));
 StringBuilder errorResult = new StringBuilder();
 String line;
 try {
   while ((line = r.readLine()) != null) {
   errorResult.append(line).append('\n');
   }
 } catch (IOException e) { 
    e.printStackTrace(); 
}
}

(A) To split a sentence into its words (space separated) you can simply use the default IFS by using

array=( $string )

Example running the following snippet

#!/bin/bash

sentence="this is the \"sentence\"   'you' want to split"
words=( $sentence )

len="${#words[@]}"
echo "words counted: $len"

printf "%s\n" "${words[@]}" ## print array

will output

words counted: 8
this
is
the
"sentence"
'you'
want
to
split

As you can see you can use single or double quotes too without any problem

Notes:
-- this is basically the same of mob's answer, but in this way you store the array for any further needing. If you only need a single loop, you can use his answer, which is one line shorter :)
-- please refer to this question for alternate methods to split a string based on delimiter.


(B) To check for a character in a string you can also use a regular expression match.
Example to check for the presence of a space character you can use:

regex='\s{1,}'
if [[ "$sentence" =~ $regex ]]
    then
        echo "Space here!";
fi

These are not command line args. Run psql. Manage to log into database (so pass the hostname, port, user and database if needed). And then write it in the psql program.

Example (below are two commands, write the first one, press enter, wait for psql to login, write the second):

psql -h host -p 5900 -U username database
\pset format aligned

C# is a little different in this respect with JavaScript. Because of the strict checks, you define the size of the array and you are supposed to know everything about the array such as its bounds, where the last item was put and what items are unused. You are supposed to copy all the elements of the array into a new, bigger one, if you want to resize it.

So, if you use a raw array, there's no other way other than to maintain the last empty, available index assign items to the array at this index, like you're already doing.

However, if you'd like to have the runtime maintain this information and completely abstract away the array, but still use an array underneath, then C# provides a class named ArrayList that provides this abstraction.

The ArrayList abstracts a loosely typed array of Objects. See the source here.

It takes care of all the issues like resizing the array, maintaining the last index that is available, etc. However, it abstracts / encapsulates this information from you. All you use is the ArrayList.

To push an item of any type into the underlying array at the end of the underlying array, call the Add method on the ArrayList like so:

/* you may or may not define a size using a constructor overload */
var arrayList = new ArrayList(); 

arrayList.Add("Foo");

EDIT: A note about type restriction

Like every programming language and runtime does, C# categorizes heap objects from those that will not go on the heap and will only stay on the function's argument stack. C# notes this distinction by the name Value types vs. Reference types. All things whose value goes on the stack are called Value types, and those that will go on the heap are called Reference types. This is loosely similar to JavaScript's distinction between objects and literals.

You can put anything into an ArrayList in C#, whether the thing is a value type or a reference type. This makes it closest to the JavaScript array in terms of typelessness, although neither of the three -- the JavaScript array, the JavaScript language and the C# ArrayList -- are actually type-less.

So, you could put a number literal, a string literal, an object of a class you made up, a boolean, a float, a double, a struct, just about anything you wanted into an ArrayList.

That is because the ArrayList internally maintains and stores all that you put into it, into an array of Objects, as you will have noted in my original answer and the linked source code.

And when you put something that isn't an object, C# creates a new object of type Object, stores the value of the thing you put into the ArrayList into this new Object type object. This process is called boxing and isn't very much unlike the JavaScript boxing mechanism.

For e.g. in JavaScript, while you could use a numeric literal to invoke a function on the Number object, you couldn't add something to the number literal's prototype.

// Valid javascript
var s = 4.toString();

// Invalid JavaScript code
4.prototype.square = () => 4 * 4;
var square = 4.square();

Just like JavaScript boxes the numeric literal 4 in the call to the toString method, C# boxes all things that are not objects into an Object type when putting them into an ArrayList.

var arrayList = new ArrayList();

arrayList.Add(4); // The value 4 is boxed into a `new Object()` first and then that new object is inserted as the last element in the `ArrayList`.

This involves a certain penalty, as it does in the case of JavaScript as well.

In C#, you can avoid this penalty as C# provides a strongly typed version of the ArrayList, known as the List<T>. So it follows that you cannot put anything into a List<T>; just T types.

However, I assume from your question's text that you already knew that C# had generic structures for strongly typed items. And your question was to have a JavaScript like data structure exhibiting the semantics of typelessness and elasticity, like the JavaScript Array object. In this case, the ArrayList comes closest.

It is also clear from your question that your interest was academic and not to use the structure in a production application.

So, I assume that for a production application, you would already know that a generic / strongly typed data structure (List<T> for example) is better performing than its non-typed one (ArrayList for example).

setTimeout() function it's use to delay a process in JavaScript.

w3schools has an easy tutorial about this function.

To explain let us create a function

 function a (name) {
  this.name = name;
 }

When JavaScript executes this code, it adds prototype property to a, prototype property is an object with two properties to it:

1. constructor
2. __proto__

So when we do

a.prototype it returns

     constructor: a  // function definition
    __proto__: Object

Now as you can see constructor is nothing but the function a itself and __proto__ points to the root level Object of JavaScript.

Let us see what happens when we use a function with new key word.

var b = new a ('JavaScript');

When JavaScript executes this code it does 4 things:

1. It creates a new object, an empty object // {}
2. It creates __proto__ on b and makes it point to a.prototype so b.__proto__ === a.prototype
3. It executes a.prototype.constructor (which is definition of function a ) with the newly created object (created in step#1) as its context (this), hence the name property passed as 'JavaScript' (which is added to this) gets added to newly created object.
4. It returns newly created object in (created in step#1) so var b gets assigned to newly created object.

Now if we add a.prototype.car = "BMW" and do b.car, the output "BMW" appears.

this is because when JavaScript executed this code it searched for car property on b, it did not find then JavaScript used b.__proto__ (which was made to point to 'a.prototype' in step#2) and finds car property so return "BMW".

You can reference those remote tracking branches ~(listed with git branch -r) with the name of their remote.

You need to fetch the remote branch:

git fetch origin aRemoteBranch

If you want to merge one of those remote branches on your local branch:

git checkout master
git merge origin/aRemoteBranch

Note 1: For a large repo with a long history, you will want to add the --depth=1 option when you use git fetch.

Note 2: These commands also work with other remote repos so you can setup an origin and an upstream if you are working on a fork.

Note 3: user3265569 suggests the following alias in the comments:

From aLocalBranch, run git combine remoteBranch
Alias:

combine = !git fetch origin ${1} && git merge origin/${1}

Opposite scenario: If you want to merge one of your local branch on a remote branch (as opposed to a remote branch to a local one, as shown above), you need to create a new local branch on top of said remote branch first:

git checkout -b myBranch origin/aBranch
git merge anotherLocalBranch

The idea here, is to merge "one of your local branch" (here anotherLocalBranch) to a remote branch (origin/aBranch).
For that, you create first "myBranch" as representing that remote branch: that is the git checkout -b myBranch origin/aBranch part.
And then you can merge anotherLocalBranch to it (to myBranch).

I got this answer from here. and its works for me

Curl has a specific option, --write-out, for this:

$ curl -o /dev/null --silent --head --write-out '%{http_code}\n' <url>
200

• -o /dev/null throws away the usual output
• --silent throws away the progress meter
• --head makes a HEAD HTTP request, instead of GET
• --write-out '%{http_code}\n' prints the required status code

To wrap this up in a complete Bash script:

#!/bin/bash
while read LINE; do
  curl -o /dev/null --silent --head --write-out "%{http_code} $LINE\n" "$LINE"
done < url-list.txt

(Eagle-eyed readers will notice that this uses one curl process per URL, which imposes fork and TCP connection penalties. It would be faster if multiple URLs were combined in a single curl, but there isn't space to write out the monsterous repetition of options that curl requires to do this.)

A scriptless, CSS-only experimental approach with image pre-loading^BONUS! and which only works in Firefox:

<style>
a.zoom .full { display: none; }
a.zoom:active .thumb { display: none; }
a.zoom:active .full { display: inline; }
</style>

<a class="zoom" href="#">
<img class="thumb" src="thumbnail.png"/>
<img class="full" src="fullsize.png"/>
</a>

Shows the thumbnail by default. Shows the full size image while the mouse button is clicked and held down. Goes back to the thumbnail as soon as the button is released. I'm in no way suggesting that this method be used; it's just a demo of a CSS-only approach that [very] partially solves the problem. With some z-index + relative position tweaks, it could work in other browsers too.

jQuery .on method is used to bind events even without the presence of element on page load. Here is the link It is used in this way:

 $("#dataTable tbody tr").on("click", function(event){
    alert($(this).text());
 });

Before jquery 1.7, .live() method was used, but it is deprecated now.

The closest thing in C# 3.0, is that you can use a constructor to initialize properties:

Stuff.Elements.Foo foo = new Stuff.Elements.Foo() {Name = "Bob Dylan", Age = 68, Location = "On Tour", IsCool = true}

This is an update for the existing answers which used bytearray() and can not work that way anymore:

>>> st = "hello world"
>>> map(bin, bytearray(st))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: string argument without an encoding

Because, as explained in the link above, if the source is a string, you must also give the encoding:

>>> map(bin, bytearray(st, encoding='utf-8'))
<map object at 0x7f14dfb1ff28>

public class ListOfLists<T> : List<List<T>>

Use FirstOrDefault or a foreach loop as already mentioned. Manually fetching an enumerator and calling Current should be avoided. foreach will dispose your enumerator for you if it implements IDisposable. When calling MoveNext and Current you have to dispose it manually (if aplicable).

Try This, It's easy way to find java installed path in Mac OS X,

The best solution is to add to your apache .htaccess file the following line after RewriteEngine On

RewriteRule ^sitemap\.xml$ sitemap.php [L]

and then simply having a file sitemap.php in your root folder that would be normally accessible via http://www.yoursite.com/sitemap.xml, the default URL where all search engines will firstly search.

The file sitemap.php shall start with

<?php
//Saturday, 11 January 2020 @kevin

header('Content-type: text/xml');
echo '<?xml version="1.0" encoding="UTF-8"?>';
?>
<urlset
      xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

it works :)

I am heavily using fast_cgi_finish_request()

In combination with a closure and register_shutdown_function()

$message ='job executed';
$backgroundJob = function() use ($message) {
     //do some work here
    echo $message;
}

Then register this closure to be executed before shutdown.

register_shutdown_function($backgroundJob);

Finally when the response was sent to the client you can close the connection to the client and continue working with the PHP process:

fast_cgi_finish_request();

The closure will be executed after fast_cgi_finish_request.

The $message will not be visible at any time. And you can register as much closures as you want, but take care about script execution time. This will only work if PHP is running as a Fast CGI module (was that right?!)

I had the same issue when getting my software running on another machine. On my developer pc (Windows 7), I had Visual Studio 2015 installed, the target pc was a clean installation of Windows 10 (.Net installed). I also tested it on another clean Windows 7 pc including .Net Framework. However, on both target pc's I needed to install the Visual C++ Redistributable for Visual Studio 2015 package for x86 or x64 (depends on what your application is build for). That was already installed on my developer pc.

My application was using a C library, which has been compiled to a C++ application using /clr and /TP options in visual studio. Also the application was providing functions to C# by using dllexport method signatures. Not sure if the C# integration leaded to give me that error or if a C++ application would have given me the same.

Hope it helps anybody.

You can use any of these commands, this will help you to give a password also.

cmd = subprocess.run(["sshpass -p 'password' ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null [email protected] ps | grep minicom"], shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
print(cmd.stdout)
OR
cmd = subprocess.getoutput("sshpass -p 'password' ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null [email protected] ps | grep minicom")
print(cmd)

... or if you want / need to keep your option 'value' as it was, just add a new attribute:

<select id="my_selection">
<option value="x" href="/link/to/somewhere">value 1</option>
<option value="y" href="/link/to/somewhere/else">value 2</option>
</select>

<script>
document.getElementById('my_selection').onchange = function() {
    window.location.href = this.children[this.selectedIndex].getAttribute('href');
}
</script>

In my case, that problem is about permissions. if you open android studio as administrator (or using sudo) then if you open the project again as normal user, android studio may not delete some files because when you open the project as administrator, some project files permissions are changed. If you lived those steps, I think you should clone the project from your VCS (git, tfs, svn etc.) again. Otherwise you have to configure project file - folder permissions.

It is interesting to note the following situation where the do {} while (0) loop won't work for you:

If you want a function-like macro that returns a value, then you will need a statement expression: ({stmt; stmt;}) instead of do {} while(0):

#include <stdio.h>

#define log_to_string1(str, fmt, arg...) \
    do { \
        sprintf(str, "%s: " fmt, "myprog", ##arg); \
    } while (0)

#define log_to_string2(str, fmt, arg...) \
    ({ \
        sprintf(str, "%s: " fmt, "myprog", ##arg); \
    })

int main() {
        char buf[1000];
        int n = 0;

        log_to_string1(buf, "%s\n", "No assignment, OK");

        n += log_to_string1(buf + n, "%s\n", "NOT OK: gcc: error: expected expression before 'do'");

        n += log_to_string2(buf + n, "%s\n", "This fixes it");
        n += log_to_string2(buf + n, "%s\n", "Assignment worked!");
        printf("%s", buf);
        return 0;
}

$(`input[id="${this.name}"]`).hide();

As you're using an ID, this would perform better

$(`#${this.name}`).hide();

I highly recommend being more specific with your approach to hiding elements via button clicks. I would opt for using data-attributes instead. For example

<input id="bx" type="text">
<button type="button" data-target="#bx" data-method="hide">Hide some input</button>

Then, in your JavaScript

// using event delegation so no need to wrap it in .ready()
$(document).on('click', 'button[data-target]', function() {
    var $this = $(this),
        target = $($this.data('target')),
        method = $this.data('method') || 'hide';
    target[method]();
});

Now you can completely control which element you're targeting and what happens to it via the HTML. For example, you could use data-target=".some-class" and data-method="fadeOut" to fade-out a collection of elements.

For anyone reading this post and looking for a why to zip the files using addFile instead of addFromString, that does not zip the files with their absolute path (just zips the files and nothing else), see my question and answer here

It might be not direct solution, but I've created a lib that allows you to use 3 fingers touch instead of shake to open dev menu, when in development mode

https://github.com/pie6k/react-native-dev-menu-on-touch

You only have to wrap your app inside:

import DevMenuOnTouch from 'react-native-dev-menu-on-touch'; // or: import { DevMenuOnTouch } from 'react-native-dev-menu-on-touch'

class YourRootApp extends Component {
  render() {
    return (
      <DevMenuOnTouch>
        <YourApp />
      </DevMenuOnTouch>
    );
  }
}

It's really useful when you have to debug on real device and you have co-workers sitting next to you.

As of 2021 insted of null i had to add {} in order to make it work!

axios.post(
        url,
        {},
        {
          params: {
            key,
            checksum
          }
        }
      )
      .then(response => {
        return success(response);
      })
      .catch(error => {
        return fail(error);
      });

I agree with above answers, the best way to get country from ip address is Maxmind.

If you want to write code in java, you might want to use i.e. geoip-api-1.2.10.jar and geoIP dat files (GeoIPCity.dat), which can be found via google.

Following code may be useful for you to get almost all information related to location, I am also using the same code.

public static String getGeoDetailsUsingMaxmind(String ipAddress, String desiredValue) 
    {
        Location getLocation;
        String returnString = "";
        try
        {
            String geoIPCity_datFile = System.getenv("AUTOMATION_HOME").concat("/tpt/GeoIP/GeoIPCity.dat");
            LookupService isp = new LookupService(geoIPCity_datFile);
            getLocation = isp.getLocation(ipAddress);
            isp.close();

            //Getting all location details 
            if(desiredValue.equalsIgnoreCase("latitude") || desiredValue.equalsIgnoreCase("lat"))
            {
                returnString = String.valueOf(getLocation.latitude);
            }
            else if(desiredValue.equalsIgnoreCase("longitude") || desiredValue.equalsIgnoreCase("lon"))
            {
                returnString = String.valueOf(getLocation.longitude);
            }
            else if(desiredValue.equalsIgnoreCase("countrycode") || desiredValue.equalsIgnoreCase("country"))
            {
                returnString = getLocation.countryCode;
            }
            else if(desiredValue.equalsIgnoreCase("countryname"))
            {
                returnString = getLocation.countryName;
            }
            else if(desiredValue.equalsIgnoreCase("region"))
            {
                returnString = getLocation.region;
            }
            else if(desiredValue.equalsIgnoreCase("metro"))
            {
                returnString = String.valueOf(getLocation.metro_code);
            }
            else if(desiredValue.equalsIgnoreCase("city"))
            {
                returnString = getLocation.city;
            }
            else if(desiredValue.equalsIgnoreCase("zip") || desiredValue.equalsIgnoreCase("postalcode"))
            {
                returnString = getLocation.postalCode;
            }
            else
            {
                returnString = "";
                System.out.println("There is no value found for parameter: "+desiredValue);
            }

            System.out.println("Value of: "+desiredValue + " is: "+returnString + " for ip address: "+ipAddress);
        }
        catch (Exception e) 
        {
            System.out.println("Exception occured while getting details from max mind. " + e);
        }
        finally
        {
            return returnString;
        }
    }

if & is used in html then you should escape it

If & is used in javascript strings e.g. an alert('This & that'); or document.href you don't need to use it.

If you're using document.write then you should use it e.g. document.write(<p>this &amp; that</p>)

There is no advantage of using one vs the other, but, there is a specific case where throw won't work. However, those cases can be fixed.

Any time you are inside of a promise callback, you can use throw. However, if you're in any other asynchronous callback, you must use reject.

For example, this won't trigger the catch:

new Promise(function() {
  setTimeout(function() {
    throw 'or nah';
    // return Promise.reject('or nah'); also won't work
  }, 1000);
}).catch(function(e) {
  console.log(e); // doesn't happen
});

Instead you're left with an unresolved promise and an uncaught exception. That is a case where you would want to instead use reject. However, you could fix this in two ways.

1. by using the original Promise's reject function inside the timeout:

new Promise(function(resolve, reject) {
  setTimeout(function() {
    reject('or nah');
  }, 1000);
}).catch(function(e) {
  console.log(e); // works!
});

2. by promisifying the timeout:

function timeout(duration) { // Thanks joews
  return new Promise(function(resolve) {
    setTimeout(resolve, duration);
  });
}

timeout(1000).then(function() {
  throw 'worky!';
  // return Promise.reject('worky'); also works
}).catch(function(e) {
  console.log(e); // 'worky!'
});

Finding all non-ascii characters gives the impression that one is either looking for unicode strings or intends to strip said characters individually.

For the former, try one of these (variable file is used for automation):

 file=file.txt ; LC_ALL=C grep -Piao '[\x80-\xFF\x20]{7,}' $file | iconv -f $(uchardet $file) -t utf-8

 file=file.txt ; pcregrep -iao '[\x80-\xFF\x20]{7,}' $file | iconv -f $(uchardet $file) -t utf-8

 file=file.txt ; pcregrep -iao '[^\x00-\x19\x21-\x7F]{7,}' $file | iconv -f $(uchardet $file) -t utf-8

Vanilla grep doesn't work correctly without LC_ALL=C as noted in the previous answers.

ASCII range is x00-x7F, space is x20, since strings have spaces the negative range omits it.

Non-ASCII range is x80-xFF, since strings have spaces the positive range adds it.

String is presumed to be at least 7 consecutive characters within the range. {7,}.

For shell readable output, uchardet $file returns a guess of the file encoding which is passed to iconv for automatic interpolation.

SELECT CASE WHEN field IS NULL THEN 'Empty' ELSE field END AS field_alias

Or more idiomatic:

SELECT coalesce(field, 'Empty') AS field_alias

You want the SortedSet implementations, namely TreeSet.

There's no easy solution. Each way has their pros and cons . But the canonical way is using the first option: multipart/form-data. As W3 recommendation guide says

The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.

We aren't sending forms,really, but the implicit principle still applies. Using base64 as a binary representation, is incorrect because you're using the incorrect tool for accomplish your goal, in other hand, the second option forces your API clients to do more job in order to consume your API service. You should do the hard work in the server side in order to supply an easy-to-consume API. The first option is not easy to debug, but when you do it, it probably never changes.

Using multipart/form-data you're sticked with the REST/http philosophy. You can view an answer to similar question here.

Another option if mixing the alternatives, you can use multipart/form-data but instead of send every value separate, you can send a value named payload with the json payload inside it. (I tried this approach using ASP.NET WebAPI 2 and works fine).

Try this,

IFS=''
while read line
do
    echo $line
done < file.txt

EDIT:

From man bash

IFS - The Internal Field Separator that is used for word
splitting after expansion and to split lines into words
with  the  read  builtin  command. The default value is
``<space><tab><newline>''

You can't but you can do it anyway like this. I needed this for jQuery-File-Upload

import json
# get this object
from flask import Response

#example data:

    js = [ { "name" : filename, "size" : st.st_size , 
        "url" : url_for('show', filename=filename)} ]
#then do this
    return Response(json.dumps(js),  mimetype='application/json')

I would like to emphasize one comment from @Jules on this answer to this question. The comment brings a useful link: Spring Injection with @Resource, @Autowired and @Inject. I encourage you to read it entirely, however here is a quick summary of its usefulness:

How annotations select the right implementation?

@Autowired and @Inject

1. Matches by Type
2. Restricts by Qualifiers
3. Matches by Name

@Resource

1. Matches by Name
2. Matches by Type
3. Restricts by Qualifiers (ignored if match is found by name)

Which annotations (or combination of) should I use for injecting my beans?

1. Explicitly name your component [@Component("beanName")]

2. Use @Resource with the name attribute [@Resource(name="beanName")]

Why should I not use @Qualifier?

Avoid @Qualifier annotations unless you want to create a list of similar beans. For example you may want to mark a set of rules with a specific @Qualifier annotation. This approach makes it simple to inject a group of rule classes into a list that can be used for processing data.

Does bean injection slow my program?

Scan specific packages for components [context:component-scan base-package="com.sourceallies.person"]. While this will result in more component-scan configurations it reduces the chance that you’ll add unnecessary components to your Spring context.

Reference: Spring Injection with @Resource, @Autowired and @Inject

You'll want to include action="javascript:void(0);" to your form to prevent page reloads and maintain HTML standard.

Why does this error occur?

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.

The first element in a collection is generally located at index 0. The last element is at index n-1, where n is the Size of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1, you're going to get an error.

How indexing arrays works

When you declare an array like this:

var array = new int[6]

The first and last elements in the array are

var firstElement = array[0];
var lastElement = array[5];

So when you write:

var element = array[5];

you are retrieving the sixth element in the array, not the fifth one.

Typically, you would loop over an array like this:

for (int index = 0; index < array.Length; index++)
{
    Console.WriteLine(array[index]);
}

This works, because the loop starts at zero, and ends at Length-1 because index is no longer less than Length.

This, however, will throw an exception:

for (int index = 0; index <= array.Length; index++)
{
    Console.WriteLine(array[index]);
}

Notice the <= there? index will now be out of range in the last loop iteration, because the loop thinks that Length is a valid index, but it is not.

How other collections work

Lists work the same way, except that you generally use Count instead of Length. They still start at zero, and end at Count - 1.

for (int index = 0; i < list.Count; index++)
{
    Console.WriteLine(list[index]);
} 

However, you can also iterate through a list using foreach, avoiding the whole problem of indexing entirely:

foreach (var element in list)
{
    Console.WriteLine(element.ToString());
}

You cannot index an element that hasn't been added to a collection yet.

var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]);  // Throws exception.

k=[[1, 2], [4], [5, 6, 2], [1, 2], [3], [5, 2], [3], [8], [9]]
kl=[]
kl.extend(x for x in k if x not in kl)
k=list(kl)
print(k)

which prints,

[[1, 2], [4], [5, 6, 2], [3], [5, 2], [8], [9]]

One trick I found was putting your setOnItemSelectedListeners in onWindowFocusChanged instead of onCreate. I haven't found any bad side-effects to doing it this way, yet. Basically, set up the listeners after the window gets drawn. I'm not sure how often onWindowFocusChanged runs, but it's easy enough to create yourself a lock variable if you are finding it running too often.

I think Android might be using a message-based processing system, and if you put it all in onCreate, you may run into situations where the spinner gets populated after it gets drawn. So, your listener will fire off after you set the item location. This is an educated guess, of course, but feel free to correct me on this.

Use java.math.BigDecimal

Doubles are binary fractions internally, so they sometimes cannot represent decimal fractions to the exact decimal.

$(function() {
    $('.phrase .items').each(function(i, items_list){
        var myText = "";

        $(items_list).find('li').each(function(j, li){
            alert(li.text());
        })

        alert(myText);

    });
};

If you want a simplest one-liner solution, then go for the accepted answer that uses regex.

However, if you want a faster solution then here's a function you can have.

console.log(isAlphaNumeric('a')); // true
console.log(isAlphaNumericString('HelloWorld96')); // true
console.log(isAlphaNumericString('Hello World!')); // false

/**
 * Function to check if a character is alpha-numeric.
 *
 * @param {string} c
 * @return {boolean}
 */
function isAlphaNumeric(c) {
  const CHAR_CODE_A = 65;
  const CHAR_CODE_Z = 90;
  const CHAR_CODE_AS = 97;
  const CHAR_CODE_ZS = 122;
  const CHAR_CODE_0 = 48;
  const CHAR_CODE_9 = 57;

  let code = c.charCodeAt(0);

  if (
    (code >= CHAR_CODE_A && code <= CHAR_CODE_Z) ||
    (code >= CHAR_CODE_AS && code <= CHAR_CODE_ZS) ||
    (code >= CHAR_CODE_0 && code <= CHAR_CODE_9)
  ) {
    return true;
  }

  return false;
}

/**
 * Function to check if a string is fully alpha-numeric.
 *
 * @param {string} s
 * @returns {boolean}
 */
function isAlphaNumericString(s) {
  for (let i = 0; i < s.length; i++) {
    if (!isAlphaNumeric(s[i])) {
      return false;
    }
  }

  return true;
}

In following code, we don't need to hard code the credentials.

service.Proxy = WebRequest.DefaultWebProxy;
service.Credentials = System.Net.CredentialCache.DefaultCredentials; ;
service.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;

These easiest way is to work with .zip files instead of .7z and use Dot Net Zip

When spinning off 7zip commands to shell there are other issues like user privileges, I had issue with SevenZipSharp.

Private Function CompressFile(filename As String) As Boolean
Using zip As New ZipFile()
    zip.AddFile(filename & ".txt", "")
    zip.Save(filename & ".zip")
End Using

Return File.Exists(filename & ".zip")
End Function

You may do a session and place it:

// Start session
session_start();

// Check do the person logged in
if($_SESSION['username']==NULL){
    // Haven't log in
    echo "You haven't log in";
}else{
    // Logged in
    echo "Successfully logged in!";
}

Note: you must make a form which contain $_SESSION['username'] = $login_input_username;

use IDLE Editor {You may already have it} it has interactive shell for python and it will show you execution and result.

Given how mangled some data can look after BCP importing into SQL Server from non-SQL data sources, I'd suggest doing all the BCP import into some scratch tables first.

For example

truncate table Address_Import_tbl

BULK INSERT dbo.Address_Import_tbl FROM 'E:\external\SomeDataSource\Address.csv' WITH ( FIELDTERMINATOR = '|', ROWTERMINATOR = '\n', MAXERRORS = 10 )

Make sure all the columns in Address_Import_tbl are nvarchar(), to make it as agnostic as possible, and avoid type conversion errors.

Then apply whatever fixes you need to Address_Import_tbl. Like deleting the unwanted header.

Then run a INSERT SELECT query, to copy from Address_Import_tbl to Address_tbl, along with any datatype conversions you need. For example, to cast imported dates to SQL DATETIME.

The function you're looking for is 'Insert'. It takes as its parameters the index you want to insert at, and an array of values to use for the new row values. Typical usage might include:

myDataGridView.Rows.Insert(4,new object[]{value1,value2,value3});

or something to that effect.

I had the same problem because I changed the user from myself to someone else:

su

For some reason, after did the normal compiling I was not able to execute it (the same error message). Directly ssh to the other user account works.

You can try with this, it worked for me

WebView wb_previewSurvey=new WebView(this); 


       wb_previewSurvey.setWebChromeClient(new WebChromeClient() {
        @Override
        public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
            //Required functionality here
            return super.onJsAlert(view, url, message, result);
        }

    });
