I had a similar issue, and following previous answers (thanks!), I was able to search and find how to handle correctly the ThreadPoolExecutor terminaison.

In my case, that just fix my progressive increase of similar blocked threads:

• I've used ExecutorService::awaitTermination(x, TimeUnit) and ExecutorService::shutdownNow() (if necessary) in my finally clause.

• For information, I've used the following commands to detect thread count & list locked threads:

  ps -u javaAppuser -L|wc -l

  jcmd `ps -C java -o pid=` Thread.print >> threadPrintDayA.log

  jcmd `ps -C java -o pid=` Thread.print >> threadPrintDayAPlusOne.log

  cat threadPrint*.log |grep "pool-"|wc -l

Dollar signs around the variable do not work on my Vista machine, but percent signs do. Also note that a trailing space on the "set" line will show up between the prompt and user input.

Okay if you've created the core dump with gcore or gdb then you'll need to convert it to something called a HPROF file. These can be used by VisualVM, Netbeans or Eclipse's Memory Analyzer Tool (formerly SAP Memory Analyzer). I'd recommend Eclipse MAT.

To convert the file use the commandline tool jmap.

# jmap -dump:format=b,file=dump.hprof /usr/bin/java core.1234

where:

dump.hprof is the name of the hprof file you wish to create

/usr/bin/java is the path to the version of the java binary that generated the core dump

core.1234 is your regular core file.

One more point I want to add. In spring-servlet.xml we include component scan for Controller package. In following example we include filter annotation for controller package.

<!-- Scans for annotated @Controllers in the classpath -->
<context:component-scan base-package="org.test.web" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

In applicationcontext.xml we add filter for remaining package excluding controller.

<context:component-scan base-package="org.test">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

As this is a High traffic post i hope to provide here an answer slightly more undetermined to the original question and thus to provide further background on a JSON Hijacking attack and its consequences

JSON Hijacking as the name suggests is an attack similar to Cross-Site Request Forgery where an attacker can access cross-domain sensitive JSON data from applications that return sensitive data as array literals to GET requests. An example of a JSON call returning an array literal is shown below:

[{"id":"1001","ccnum":"4111111111111111","balance":"2345.15"}, 
{"id":"1002","ccnum":"5555555555554444","balance":"10345.00"}, 
{"id":"1003","ccnum":"5105105105105100","balance":"6250.50"}]

This attack can be achieved in 3 major steps:

Step 1: Get an authenticated user to visit a malicious page. Step 2: The malicious page will try and access sensitive data from the application that the user is logged into.This can be done by embedding a script tag in an HTML page since the same-origin policy does not apply to script tags.

<script src="http://<jsonsite>/json_server.php"></script>

The browser will make a GET request to json_server.php and any authentication cookies of the user will be sent along with the request. Step 3: At this point while the malicious site has executed the script it does not have access to any sensitive data. Getting access to the data can be achieved by using an object prototype setter. In the code below an object prototypes property is being bound to the defined function when an attempt is being made to set the "ccnum" property.

Object.prototype.__defineSetter__('ccnum',function(obj){

secrets =secrets.concat(" ", obj);

});

At this point the malicious site has successfully hijacked the sensitive financial data (ccnum) returned byjson_server.php JSON

It should be noted that not all browsers support this method; the proof of concept was done on Firefox 3.x.This method has now been deprecated and replaced by the useObject.defineProperty There is also a variation of this attack that should work on all browsers where full named JavaScript (e.g. pi=3.14159) is returned instead of a JSON array.

There are several ways in which JSON Hijacking can be prevented:

• Since SCRIPT tags can only generate HTTP GET requests, only return JSON objects to POST requests.

• Prevent the web browser from interpreting the JSON object as valid JavaScript code.

• Implement Cross-Site Request Forgery protection by requiring that a predefined random value be required for all JSON requests.

so as you can see While(1) comes under the last option. In the most simple terms, while(1) is an infinite loop which will run till a break statement is issued explicitly. And thus what would be described as a lock for the key to be applied (google break statement). Therefore a JSON hijacking, in which the Hacker has no key will be consistently dismissed.Alas, If you read the JSON block with a parser, the while(1) loop is ignored.

So in conclusion, the while(1) loop can more easily visualised as a simple break statement cipher that google can use to control flow of data.

However the key word in that statement is the word 'simple'. The usage of authenticated infinite loops has been thankfully removed from basic practice in the years since 2010 due to its absolute decimation of CPU usage when isolated (and the fact the internet has moved away from forcing through crude 'quick-fixes'). Today instead the codebase has preventative measures embedded and the system is not crucial nor effective anymore. (part of this is the move away from JSON Hijacking to more fruitful datafarming techniques that i wont go into at present)

*

var str   = 'asd-0.testing';
var regex = /(asd-)\d(\.\w+)/;
str = str.replace(regex, "$11$2");
console.log(str);

Or if you're sure there won't be any other digits in the string:

var str   = 'asd-0.testing';
var regex = /\d/;
str = str.replace(regex, "1");
console.log(str);

Use restart: always in your docker compose file.

Docker-compose up -d will launch container from images again. Use docker-compose start to start the stopped containers, it never launches new containers from images.

nginx:   
    restart: always   
    image: nginx   
    ports:
      - "80:80"
      - "443:443"   links:
      - other_container:other_container

Also you can write the code up in the docker file so that it gets created first, if it has the dependency of other containers.

If you have bigger version than v4.9 of Highcharts you can use visible: false in the xAxis and yAxis settings.

Example:

$('#container').highcharts({

    chart: {
        type: 'column'
    },

    title: {
        text: 'Highcharts axis visibility'
    },

    xAxis: {
        visible: false
    },

    yAxis: {
        title: {
            text: 'Fruit'
        },
        visible: false
    }

});

If you want to set the image as the background, I've got a solution:

.image {
    background-image: url(yourimage.jpg);
    background-position: center;
}

Worked for me

<script type="text/javascript">


 if (typeof window.event != 'undefined')
    document.onkeydown = function()
    {
        if (event.srcElement.tagName.toUpperCase() != 'INPUT')
            return (event.keyCode != 8);
    }
else
    document.onkeypress = function(e)
    {
        if (e.target.nodeName.toUpperCase() != 'INPUT')
            return (e.keyCode != 8);
    }

</script>

So to fix this properly, I did what others here did and used css to get hide the horizontal toolbar:

.name {
  max-width: 100%;
  overflow-x: hidden;
}

Then in js, I created an event listener to look for scrolling, and counteracted the users attempted horizontal scroll.

var scrollEventHandler = function()
{
  window.scroll(0, window.pageYOffset)
}

window.addEventListener("scroll", scrollEventHandler, false);

I saw somebody do something similar, but apparently that didn't work. This however is working perfectly fine for me.

image.SetAbsolutePosition(1,1);

I found that the problem was to do with Powershell not being able to run scripts, if that's the case for you, here is the solution.

In my own case I have the following error

Illegal mix of collations (utf8_general_ci,IMPLICIT) and (utf8_unicode_ci,IMPLICIT) for operation '='

$this->db->select("users.username as matric_no, CONCAT(users.surname, ' ', users.first_name, ' ', users.last_name) as fullname") ->join('users', 'users.username=classroom_students.matric_no', 'left') ->where('classroom_students.session_id', $session) ->where('classroom_students.level_id', $level) ->where('classroom_students.dept_id', $dept);

After weeks of google searching I noticed that the two fields I am comparing consists of different collation name. The first one i.e username is of utf8_general_ci while the second one is of utf8_unicode_ci so I went back to the structure of the second table and changed the second field (matric_no) to utf8_general_ci and it worked like a charm.

Using plyr::ldply there is roughly a 50% speed increase by enabling the .parallel option while reading 400 csv files roughly 30-40 MB each. Example includes a text progress bar.

library(plyr)
library(data.table)
library(doSNOW)

csv.list <- list.files(path="t:/data", pattern=".csv$", full.names=TRUE)

cl <- makeCluster(4)
registerDoSNOW(cl)

pb <- txtProgressBar(max=length(csv.list), style=3)
pbu <- function(i) setTxtProgressBar(pb, i)
dt <- setDT(ldply(csv.list, fread, .parallel=TRUE, .paropts=list(.options.snow=list(progress=pbu))))

stopCluster(cl)

There is obviously another process listening on the port. You might find out that process by using the following command:

$ lsof -i :8000

or change your tornado app's port. tornado's error info not Explicitly on this.

If anyone else runs into this issue and none of the above solutions work due to "Duplicate identifier" issues, run this:

npm install typings --global

With older versions of typings things mess up and you'll get a bunch of "Duplicate identifier" issues. Also you don't need to use --ambient anymore as far as I could tell.

So once typings is up to date, this should work (using the Angular 2 quickstart).

Run:

npm install lodash --save 
typings install lodash --save

First, add this to systemjs.config.js:

'lodash':                     'node_modules/lodash/lodash.js'

Now you can use this in any file: import * as _ from 'lodash';

Delete your typings folder and run npm install if you're still having issues.

Going down your list:

• "Unicode" isn't an encoding, although unfortunately, a lot of documentation imprecisely uses it to refer to whichever Unicode encoding that particular system uses by default. On Windows and Java, this often means UTF-16; in many other places, it means UTF-8. Properly, Unicode refers to the abstract character set itself, not to any particular encoding.
• UTF-16: 2 bytes per "code unit". This is the native format of strings in .NET, and generally in Windows and Java. Values outside the Basic Multilingual Plane (BMP) are encoded as surrogate pairs. These used to be relatively rarely used, but now many consumer applications will need to be aware of non-BMP characters in order to support emojis.
• UTF-8: Variable length encoding, 1-4 bytes per code point. ASCII values are encoded as ASCII using 1 byte.
• UTF-7: Usually used for mail encoding. Chances are if you think you need it and you're not doing mail, you're wrong. (That's just my experience of people posting in newsgroups etc - outside mail, it's really not widely used at all.)
• UTF-32: Fixed width encoding using 4 bytes per code point. This isn't very efficient, but makes life easier outside the BMP. I have a .NET Utf32String class as part of my MiscUtil library, should you ever want it. (It's not been very thoroughly tested, mind you.)
• ASCII: Single byte encoding only using the bottom 7 bits. (Unicode code points 0-127.) No accents etc.
• ANSI: There's no one fixed ANSI encoding - there are lots of them. Usually when people say "ANSI" they mean "the default locale/codepage for my system" which is obtained via Encoding.Default, and is often Windows-1252 but can be other locales.

There's more on my Unicode page and tips for debugging Unicode problems.

The other big resource of code is unicode.org which contains more information than you'll ever be able to work your way through - possibly the most useful bit is the code charts.

A quick solution if you only want to display a message or a loader gif until the download dialog is displayed is to put the message in a hidden container and when you click on the button that generate the file to be downloaded you make the container visible. Then use jquery or javascript to catch the focusout event of the button to hide the container that contain the message

You could use what sep16 on php.net recommends:

<?php

parse_str(implode('&', array_slice($argv, 1)), $_GET);

?>

It behaves exactly like you'd expect with cgi-php.

$ php -f myfile.php type=daily a=1 b[]=2 b[]=3

will set $_GET['type'] to 'daily', $_GET['a'] to '1' and $_GET['b'] to array('2', '3').

class Student{
    //instance variable or data members.

    Map<Integer, List<Object>> mapp = new HashMap<Integer, List<Object>>();
    Scanner s1 = new Scanner(System.in);
    String name = s1.nextLine();
    int regno ;
    int mark1;
    int mark2;
    int total;
    List<Object> list = new ArrayList<Object>();
    mapp.put(regno,list); //what wrong in this part?
    list.add(mark1);
    list.add(mark2);**
    //String mark2=mapp.get(regno)[2];
}

let leng = yourString.split(' ').filter(a => a.trim().length > 0).length

One problem here is that your method expects int values while you are passing string from ajax call. Try to change it to string and parse inside the webmethod if necessary :

[System.Web.Services.WebMethod]
public static string AddTo_Cart(string quantity, string itemId)
{
    //parse parameters here
    SpiritsShared.ShoppingCart.AddItem(itemId, quantity);      
    return "Add";
}

Edit : or Pass int parameters from ajax call.

foreach over a statement is just a syntax sugar for the regular one-way fetch() loop. If you want to loop over your data more than once, select it as a regular array first

$sql = "SELECT * FROM users";
$stm = $dbh->query($sql);
// here you go:
$users = $stm->fetchAll();

foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
echo "<br/>";
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

Also quit that try..catch thing. Don't use it, but set the proper error reporting for PHP and PDO

Apart from the methods mentioned earlier. You can also use the command del to remove multiple variables

del variable1,variable2

They are the same thing, aren't they?

No, they aren't.

I think the first sentence of the Wikipedia page you referenced gives a nice, brief summary:

UTF-8 is a variable width character encoding capable of encoding all 1,112,064 valid code points in Unicode using one to four 8-bit bytes.

To elaborate:

• Unicode is a standard, which defines a map from characters to numbers, the so-called code points, (like in the example below). For the full mapping, you can have a look here.

  ! -> U+0021 (21),  
  " -> U+0022 (22),  
  \# -> U+0023 (23)
  

• UTF-8 is one of the ways to encode these code points in a form a computer can understand, aka bits. In other words, it's a way/algorithm to convert each of those code points to a sequence of bits or convert a sequence of bits to the equivalent code points. Note that there are a lot of alternative encodings for Unicode.

Joel gives a really nice explanation and an overview of the history here.

SELECT ColumnA, COUNT( * )

I modify it in the .env APP_TIMEZONE.

For Colombia: APP_TIMEZONE = America / Bogota also for paris like this: APP_TIMEZONE = Europe / Paris

Source: https://www.php.net/manual/es/timezones.europe.php

EDIT: After further investigation, my original assumption that this was an anomaly (bug?) of the declare @var datatype = value syntax is incorrect.

I modified your script for 2005 since that syntax is not supported, then tried the modified version on 2008. In 2005, I get the Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. error message. In 2008, the modified script is still successful.

declare @KMsg varchar(max); set @KMsg = REPLICATE('a',1024);
declare @MMsg varchar(max); set @MMsg = REPLICATE(@KMsg,1024);
declare @GMsg varchar(max); set @GMsg = REPLICATE(@MMsg,1024);
declare @GGMMsg varchar(max); set @GGMMsg = @GMsg + @GMsg + @MMsg;
select LEN(@GGMMsg)

Likewise, I saw this error as a result of too little RAM. I cranked up the RAM on the VM and the error disappeared.

You can store any kind of data in a session using:

Session["VariableName"]=value;

This variable will last 20 mins or so.

My psychic debugging skills tell me that your submit button is named submit.
Therefore, form.submit refers to the button rather than the method.

Rename the button to something else so that form.submit refers to the method again.

Problem seems that you are not handling GET requests appropriately or directly posting the data without first getting the form.

When you first access the page, client will send GET request, in that case you should send html with appropriate form.

Later, user fills up the form and sends POST request with form data.

Your view should be:

def deposit(request,account_num):
   if request.method == 'POST':
      form_=AccountForm(request.POST or None, instance=account)
      if form.is_valid(): 
          #handle form data
          return HttpResponseRedirect("/history/" + account_num + "/")
      else:
         #handle when form not valid
    else:
       #handle when request is GET (or not POST)
       form_=AccountForm(instance=account)

    return render_to_response('history.html',
                          {'account_form': form},
                          context_instance=RequestContext(request))

you can disable or set date and time for log setting.

I had a simmilar problem, but in my case I was put a row in the leading of the Listview, and it was consumming all the space, of course. I just had to take the Row out of the leading, and it was solved. I would recomend to check if the problem is a widget larger than its containner can have.

Another option is to disable this functionality. If we allow access on the server only for reading Disable pmadb

1. add config for server

$cfg['Servers'][$i]['userconfig'] =false;
$cfg['Servers'][$i]['pmadb'] = false;
$cfg['Servers'][$i]['bookmarktable'] = false;
$cfg['Servers'][$i]['relation'] = false;
$cfg['Servers'][$i]['table_info'] = false;
$cfg['Servers'][$i]['table_coords'] = false;
$cfg['Servers'][$i]['pdf_pages'] = false;

$cfg['Servers'][$i]['tracking'] = false;
$cfg['Servers'][$i]['designer_coords'] = false;
$cfg['Servers'][$i]['userconfig'] = false;
$cfg['Servers'][$i]['recent'] = false;

2. and refresh session (private tab browser or other)

if you are on a Debian based server (such as Ubuntu) you can run the following command:

apt-get install php-gd

Then once it is complete run:

/etc/init.d/apache2 restart

This will restart your server and enable GD in PHP.

If you are on another type of system you will need to use something else (like yum install) or compile directly into PHP.

String str_date="13-09-2011";
DateFormat formatter ; 
Date date ; 
formatter = new SimpleDateFormat("dd-MM-yyyy");
date = (Date)formatter.parse(str_date); 
System.out.println("Today is " +date.getTime());

Try this

you can use this code .may be solve the problem

Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://192.168.43.1:6789/mobile_base/test.apk"));
startActivity(intent);

For this you have two choices:

• A downgrade to python 2.6. This is generally undesirable because it is backtracking and may nullify a small portion of your scripts
• Your second option is to use some form of exe converter. I recommend pyinstaller as it seems to have the best results.

Assume file is already created in the predefined directory with name "table.txt"

• 1) change the ownership for file :

  sudo chown username:username table.txt
  

• 2) change the mode of the file

  sudo chmod 777 table.txt
  

Now, try it should work!

Five options:

• Use the free jsonutils web tool without installing anything.

• If you have Web Essentials in Visual Studio, use Edit > Paste special > paste JSON as class.

• Use the free jsonclassgenerator.exe

• The web tool app.quicktype.io does not require installing anything.

• The web tool json2csharp also does not require installing anything.

Pros and Cons:

• jsonclassgenerator converts to PascalCase but the others do not.

• app.quicktype.io has some logic to recognize dictionaries and handle JSON properties whose names are invalid c# identifiers.

You can use this ng-switch:

<div ng-app ng-controller="friendsCtrl">
  <label>Search: </label><input ng-model="searchText" type="text">
  <div ng-init="filtered = (friends | filter:searchText)">
  <h3>'Found '{{(friends | filter:searchText).length}} friends</h3>
  <div ng-switch="(friends | filter:searchText).length">
    <span class="ng-empty" ng-switch-when="0">No friends</span>
    <table ng-switch-default>
      <thead>  
        <tr>
          <th>Name</th>
          <th>Phone</th>
        </tr>
      </thead>
      <tbody>
      <tr ng-repeat="friend in friends | filter:searchText">
        <td>{{friend.name}}</td>
        <td>{{friend.phone}}</td>
      </tr>
    </tbody>

In my own case, i was using serialize() on the form, Hence the files were not being sent to php. If you are using jquery, use FormData(). For example

<form id='form'>
<input type='file' name='file' />
<input type='submit' />
</form>

Using jquery,

$('#form').submit(function (e) {
e.preventDefault();
var formData = new FormData(this); // grab all form contents including files
//you can then use formData and pass to ajax

});

This error happens because of your Jre version of Eclipse and Tomcat are mismatched ..either change eclipse one to tomcat one or ViceVersa..

Both should be same ..Java version mismatched ..Check it

A Simple Approach will be to use a normal link and add Bootstrap modal effect to it. Just make use of my Code, hopefully you will get it run.

 <div class="container">
        <div class="row">
            <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="addContact" aria-hidden="true">
                <div class="modal-dialog">
                    <div class="modal-content">
                        <div class="modal-header">
                            <button type="button" class="close" data-dismiss="modal" aria-hidden="true"><b style="color:#fb3600; font-weight:700;">X</b></button><!--&times;-->
                            <h4 class="modal-title text-center" id="addContact">Add Contact</h4>
                        </div>
                        <div class="modal-body">
                            <div class="row">
                                <ul class="nav nav-tabs">

                                </div>

                            </div>

To do this via TSQL (ssms query window or sqlcmd.exe) just run:

RESTORE DATABASE MyDatabase FROM DISK='c:\backups\MyDataBase1.bak'

To do it via GUI - open SSMS, right click on Databases and follow the steps below

Here is the example directly from PEP 8 on limiting line length:

class Rectangle(Blob):

    def __init__(self, width, height,
                 color='black', emphasis=None, highlight=0):
        if (width == 0 and height == 0 and
                color == 'red' and emphasis == 'strong' or
                highlight > 100):
            raise ValueError("sorry, you lose")
        if width == 0 and height == 0 and (color == 'red' or
                                           emphasis is None):
            raise ValueError("I don't think so -- values are %s, %s" %
                             (width, height))
        Blob.__init__(self, width, height,
                      color, emphasis, highlight)

If you want the number of rows to be flexible, you can add row_number in the SQL. For SQL server:

SELECT ROW_NUMBER() OVER (ORDER BY myOrder) ROW_NUMBER, * FROM myTable

Then filter the datatable on row_number:

Dataview dv= new Dataview(dt, "ROW_NUMBER<=100", "", CurrentRows)

The mentioned solutions deleteDir() and cleanWs() (if using the workspace cleanup plugin) both work, but the recommendation to use it in an extra build step is usually not the desired solution. If the build fails and the pipeline is aborted, this cleanup-stage is never reached and therefore the workspace is not cleaned on failed builds.

=> In most cases you should probably put it in a post-built-step condition like always:

pipeline {
    agent any
    stages {
        stage('Example') {
            steps {
                echo 'Hello World'
            }
        }
    }
    post { 
        always { 
            cleanWs()
        }
    }
}

Example solution for adding the library to your PYTHONPATH.

1. Add the following line into your ~/.bashrc or just run it directly:

   export PYTHONPATH="$PYTHONPATH:$HOME/.python"
   

2. Then link your required library into your ~/.python folder, e.g.

   ln -s /home/user/work/project/foo ~/.python/
   

Relying on the PDF that @CBroe posted earlier:

If you want to toggle a class to an element using native solution, you could try this suggestion. I have tasted it in different cases, with or without other classes onto the element, and I think it works pretty much:

(function(objSelector, objClass){
   document.querySelectorAll(objSelector).forEach(function(o){
      o.addEventListener('click', function(e){
        var $this = e.target,
            klass = $this.className,
            findClass = new RegExp('\\b\\s*' + objClass + '\\S*\\s?', 'g');

        if( !findClass.test( $this.className ) )
            if( klass ) 
                $this.className = klass + ' ' + objClass;
            else 
                $this.setAttribute('class', objClass);
        else 
        {
            klass = klass.replace( findClass, '' );
            if(klass) $this.className = klass;
            else $this.removeAttribute('class');
        }
    });
  });
})('.yourElemetnSelector', 'yourClass');

Blowfish is not a hashing algorithm. It's an encryption algorithm. What that means is that you can encrypt something using blowfish, and then later on you can decrypt it back to plain text.

SHA512 is a hashing algorithm. That means that (in theory) once you hash the input you can't get the original input back again.

They're 2 different things, designed to be used for different tasks. There is no 'correct' answer to "is blowfish better than SHA512?" You might as well ask "are apples better than kangaroos?"

If you want to read some more on the topic here's some links:

When you push a new branch the first time use: >git push -u origin

After that, you can just type a shorter command: >git push

The first-time -u option created a persistent upstream tracking branch with your local branch.

This started out as an attempt to cast video from my pc to a tv (with subtitles) eventually using Chromecast. And I ended up in this "does not play mp4" situation. However I seemed to have proved that Chrome will play (exactly the same) mp4 as long as it isn't wrapped in html(5) So here is what I have constructed. I have made a webpage under localhost and in there is a default.htm which contains:-

<!DOCTYPE html>
<html>
<head>
</head>
<body>
<video  controls >
 <source src="sample.mp4" type="video/mp4">
 <track kind="subtitles" src="sample.vtt" label="gcsubs" srclang="eng">
</video>
</body>
</html>

the video and subtitle files are stored in the same folder as default.htm

I have the very latest version of Chrome (just updated this morning)

When I type the appropriate localhost... into my Chrome browser a black square appears with a "GO" arrow and an elapsed time bar, a mute button and an icon which says "CC". If I hit the go arrow, nothing happens (it doesn't change to "pause", the elapsed time doesn't move, and the timer sticks at 0:00. There are no error messages - nothing!

(note that if I input localhost.. to IE11 the video plays!!!!

In Chrome if I enter the disc address of sample.mp4 (i.e. C:\webstore\sample.mp4 then Chrome will play the video fine?.

This last bit is probably a working solution for Chromecast except that I cannot see any subtitles. I really want a solution with working subtitles. I just don't understand what is different in Chrome between the two methods of playing mp4

I thought I just saw this question.

In short, no, there's no variable interpolation within an application configuration.

You have two options

1. You could roll your own to substitute variables at runtime
2. At build time, massage the application configuration to the particular specifics of the target deployment environment. Some details on this at dealing with the configuration-nightmare

Here is how I do it. This way I can actually get a function to simulate returning multiple values;

function foo($array) 
{ 
    foreach($array as $_key => $_value) 
    {
       $str .= "{$_key}=".$_value.'&';
    }
    return $str = substr($str, 0, -1);
} 

/* Set the variables to pass to function, in an Array */

    $waffles['variable1'] = "value1"; 
    $waffles['variable2'] = "value2"; 
    $waffles['variable3'] = "value3"; 

/* Call Function */

    parse_str( foo( $waffles ));

/* Function returns multiple variable/value pairs */

    echo $variable1 ."<br>";
    echo $variable2 ."<br>";
    echo $variable3 ."<br>";

Especially usefull if you want, for example all fields in a database to be returned as variables, named the same as the database table fields. See 'db_fields( )' function below.

For example, if you have a query

select login, password, email from members_table where id = $id

Function returns multiple variables:

$login, $password and $email

Here is the function:

function db_fields($field, $filter, $filter_by,  $table = 'members_table') {

 /*
    This function will return as variable names, all fields that you request, 
    and the field values assigned to the variables as variable values.  

    $filter_by = TABLE FIELD TO FILTER RESULTS BY
    $filter =  VALUE TO FILTER BY
    $table = TABLE TO RUN QUERY AGAINST

    Returns single string value or ARRAY, based on whether user requests single
    field or multiple fields.

    We return all fields as variable names. If multiple rows
    are returned, check is_array($return_field); If > 0, it contains multiple rows.
    In that case, simply run parse_str($return_value) for each Array Item. 
*/
    $field = ($field == "*") ? "*,*" : $field;
    $fields = explode(",",$field);

    $assoc_array = ( count($fields) > 0 ) ? 1 : 0;

    if (!$assoc_array) {
        $result = mysql_fetch_assoc(mysql_query("select $field from $table where $filter_by = '$filter'"));
        return ${$field} = $result[$field];
    }
    else
    {
        $query = mysql_query("select $field from $table where $filter_by = '$filter'");
        while ($row = mysql_fetch_assoc($query)) {
            foreach($row as $_key => $_value) {
                $str .= "{$_key}=".$_value.'&';
            }
            return $str = substr($str, 0, -1);
        }
    }
}

Below is a sample call to function. So, If we need to get User Data for say $user_id = 12345, from the members table with fields ID, LOGIN, PASSWORD, EMAIL:

$filter = $user_id;
$filter_by = "ID";
$table_name = "members_table"

parse_str(db_fields('LOGIN, PASSWORD, EMAIL', $filter, $filter_by, $table_name));

/* This will return the following variables: */

echo $LOGIN ."<br>";
echo $PASSWORD ."<br>";
echo $EMAIL ."<br>";

We could also call like this:

parse_str(db_fields('*', $filter, $filter_by, $table_name));

The above call would return all fields as variable names.

If you're wondering how to get the file content from each ZipEntry it's actually quite simple. Here's a sample code:

public static void main(String[] args) throws IOException {
    ZipFile zipFile = new ZipFile("C:/test.zip");

    Enumeration<? extends ZipEntry> entries = zipFile.entries();

    while(entries.hasMoreElements()){
        ZipEntry entry = entries.nextElement();
        InputStream stream = zipFile.getInputStream(entry);
    }
}

Once you have the InputStream you can read it however you want.

If you need to support IE 8 or earlier, you can use jQuery to accomplish this.

var a = [1,2,2,3,4,3,5];
var unique = $.grep(a, function (item, index) {
   return index === $.inArray(item, a);
});

By default WampServer is installed to port 80 which is already used by IIS. To set WampServer to use an open port, left click on the WampServer icon in the system tray and go to Apache > httpd.conf

Open the httpd.conf in Notepad. press ctrl+f and search for "Listen 80", change this line to "Listen 8080" (u can change this port as what you want), and then close and save the httpd.conf file.

Open a web browser and enter "[];, this will open the WampServer configuration page where you can configure Apache, MySQL, and PHP.

and some times this problem may occur because of skype also use 80 as default port hope this will help

More simplified:

resultList.Remove(resultList.Single(x => x.Id == 2));

there is no needing to create a new var object.

Most of the other answers point to eager loading, but I found another solution.

In my case I had an EF object InventoryItem with a collection of InvActivity child objects.

class InventoryItem {
...
   // EF code first declaration of a cross table relationship
   public virtual List<InvActivity> ItemsActivity { get; set; }

   public GetLatestActivity()
   {
       return ItemActivity?.OrderByDescending(x => x.DateEntered).SingleOrDefault();
   }
...
}

And since I was pulling from the child object collection instead of a context query (with IQueryable), the Include() function was not available to implement eager loading. So instead my solution was to create a context from where I utilized GetLatestActivity() and attach() the returned object:

using (DBContext ctx = new DBContext())
{
    var latestAct = _item.GetLatestActivity();

    // attach the Entity object back to a usable database context
    ctx.InventoryActivity.Attach(latestAct);

    // your code that would make use of the latestAct's lazy loading
    // ie   latestAct.lazyLoadedChild.name = "foo";
}

Thus you aren't stuck with eager loading.

split was updated in coreutils release 8.8 (announced 22 Dec 2010) with the --number option to generate a specific number of files. The option --number=l/n generates n files without splitting lines.

The W3C solution:

var len = document.getElementById("input1").length;

Also constructor based initialisation will not work as intended whenever some kind of proxying or remoting is involved.

The ct will get called whenever an EJB gets deserialized, and whenever a new proxy gets created for it...

Jelly Bean adds support for this with the ActivityOptions.makeCustomAnimation() method. Of course, since it's only on Jelly Bean, it's pretty much worthless for practical purposes.

Reading through this helps solve a similar problem. The data is in decimal datatype - [DOB] [decimal](8, 0) NOT NULL - eg - 19700109. I want to get at the month. The solution is to combine SUBSTRING with CONVERT to VARCHAR.

    SELECT [NUM]
       ,SUBSTRING(CONVERT(VARCHAR, DOB),5,2) AS mob
    FROM [Dbname].[dbo].[Tablename] 

use state is not always needed you can just simply do this

let paymentList = [
    {"id":249,"txnid":"2","fname":"Rigoberto"}, {"id":249,"txnid":"33","fname":"manuel"},]

then use your data in a map loop like this in my case it was just a table and im sure many of you are looking for the same. here is how you use it.

<div className="card-body">
            <div className="table-responsive">
                <table className="table table-striped">
                    <thead>
                        <tr>
                            <th>Transaction ID</th>
                            <th>Name</th>
                        </tr>
                    </thead>
                    <tbody>
                        {
                            paymentList.map((payment, key) => (
                                <tr key={key}>
                                    <td>{payment.txnid}</td>
                                    <td>{payment.fname}</td>
                                </tr>
                            ))
                        }
                    </tbody>
                </table>
            </div>
        </div>

Do configure --help and see what other options are available.

It is very common to provide different options to override different locations. By standard, --prefix overrides all of them, so you need to override config location after specifying the prefix. This course of actions usually works for every automake-based project.

The worse case scenario is when you need to modify the configure script, or even worse, generated makefiles and config.h headers. But yeah, for Xfce you can try something like this:

./configure --prefix=/home/me/somefolder/mybuild/output/target --sysconfdir=/etc 

I believe that should do it.

A constructor is basically a method that you can use to ensure that objects of your class are born valid. This is the main motivation for a constructor.

Let's say you want your class has a single integer field that should be always larger than zero. How do you do that in a way that is reliable?

public class C {
     private int number;

     public C(int number) {
        setNumber(number);
     }

     public void setNumber(int number) {
        if (number < 1) {
            throws IllegalArgumentException("C cannot store anything smaller than 1");
        }
        this.number = number;
     }
}

In the code above, it may look like you are doing something redundant, but in fact you are ensuring that the number is always valid no matter what.

"initialize the instances of a class" is what a constructor does, but not the reason why we have constructors. The question is about the purpose of a constructor. You can also initialize instances of a class externally, using c.setNumber(10) in the example above. So a constructor is not the only way to initialize instances.

The constructor does that but in a way that is safe. In other words, a class alone solves the whole problem of ensuring their objects are always in valid states. Not using a constructor will leave such validation to the outside world, which is bad design.

Here is another example:

public class Interval {
    private long start;
    private long end;

    public Interval(long start, long end) {
        changeInterval(start, end);
    }

    public void changeInterval(long start, long end) {
        if (start >= end) {
            throw new IllegalArgumentException("Invalid interval.");
        }
        this.start = start;
        this.end = end;
    }
    public long duration() {
        return end - start;
    }
}

The Interval class represents a time interval. Time is stored using long. It does not make any sense to have an interval that ends before it starts. By using a constructor like the one above it is impossible to have an instance of Interval at any given moment anywhere in the system that stores an interval that does not make sense.

You could use the @Consumes annotation to get the full body:

import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;

@Path("doc")
public class BodyResource
{
  @POST
  @Consumes(MediaType.APPLICATION_XML)
  public void post(Document doc) throws TransformerConfigurationException, TransformerException
  {
    Transformer tf = TransformerFactory.newInstance().newTransformer();
    tf.transform(new DOMSource(doc), new StreamResult(System.out));
  }
}

Note: Don't forget the "Content-Type: application/xml" header by the request.

If you're removing the path for Python 3 specifically, I found it in ~/.zprofile and ~/.zshrc.

for example on debian

sudo gpasswd -a svn-admin www-data
sudo chgrp -R www-data svn/
sudo chmod -R g=rwsx svn/

A more up to date solution, for encoding:

// This is the same for all of the below, and
// you probably won't need it except for debugging
// in most cases.
function bytesToHex(bytes) {
  return Array.from(
    bytes,
    byte => byte.toString(16).padStart(2, "0")
  ).join("");
}

// You almost certainly want UTF-8, which is
// now natively supported:
function stringToUTF8Bytes(string) {
  return new TextEncoder().encode(string);
}

// But you might want UTF-16 for some reason.
// .charCodeAt(index) will return the underlying
// UTF-16 code-units (not code-points!), so you
// just need to format them in whichever endian order you want.
function stringToUTF16Bytes(string, littleEndian) {
  const bytes = new Uint8Array(string.length * 2);
  // Using DataView is the only way to get a specific
  // endianness.
  const view = new DataView(bytes.buffer);
  for (let i = 0; i != string.length; i++) {
    view.setUint16(i, string.charCodeAt(i), littleEndian);
  }
  return bytes;
}

// And you might want UTF-32 in even weirder cases.
// Fortunately, iterating a string gives the code
// points, which are identical to the UTF-32 encoding,
// though you still have the endianess issue.
function stringToUTF32Bytes(string, littleEndian) {
  const codepoints = Array.from(string, c => c.codePointAt(0));
  const bytes = new Uint8Array(codepoints.length * 4);
  // Using DataView is the only way to get a specific
  // endianness.
  const view = new DataView(bytes.buffer);
  for (let i = 0; i != codepoints.length; i++) {
    view.setUint32(i, codepoints[i], littleEndian);
  }
  return bytes;
}

Examples:

bytesToHex(stringToUTF8Bytes("hello ?? "))
// "68656c6c6f20e6bca2e5ad9720f09f918d"
bytesToHex(stringToUTF16Bytes("hello ?? ", false))
// "00680065006c006c006f00206f225b570020d83ddc4d"
bytesToHex(stringToUTF16Bytes("hello ?? ", true))
// "680065006c006c006f002000226f575b20003dd84ddc"
bytesToHex(stringToUTF32Bytes("hello ?? ", false))
// "00000068000000650000006c0000006c0000006f0000002000006f2200005b57000000200001f44d"
bytesToHex(stringToUTF32Bytes("hello ?? ", true))
// "68000000650000006c0000006c0000006f00000020000000226f0000575b0000200000004df40100"

For decoding, it's generally a lot simpler, you just need:

function hexToBytes(hex) {
    const bytes = new Uint8Array(hex.length / 2);
    for (let i = 0; i !== bytes.length; i++) {
        bytes[i] = parseInt(hex.substr(i * 2, 2), 16);
    }
    return bytes;
}

then use the encoding parameter of TextDecoder:

// UTF-8 is default
new TextDecoder().decode(hexToBytes("68656c6c6f20e6bca2e5ad9720f09f918d"));
// but you can also use:
new TextDecoder("UTF-16LE").decode(hexToBytes("680065006c006c006f002000226f575b20003dd84ddc"))
new TextDecoder("UTF-16BE").decode(hexToBytes("00680065006c006c006f00206f225b570020d83ddc4d"));
// "hello ?? "

Here's the list of allowed encoding names: https://www.w3.org/TR/encoding/#names-and-labels

You might notice UTF-32 is not on that list, which is a pain, so:

function bytesToStringUTF32(bytes, littleEndian) {
  const view = new DataView(bytes.buffer);
  const codepoints = new Uint32Array(view.byteLength / 4);
  for (let i = 0; i !== codepoints.length; i++) {
    codepoints[i] = view.getUint32(i * 4, littleEndian);
  }
  return String.fromCodePoint(...codepoints);
}

Then:

bytesToStringUTF32(hexToBytes("00000068000000650000006c0000006c0000006f0000002000006f2200005b57000000200001f44d"), false)
bytesToStringUTF32(hexToBytes("68000000650000006c0000006c0000006f00000020000000226f0000575b0000200000004df40100"), true)
// "hello ?? "

I had the same problem, when I used a inline-block on my menu I had the space between each "li" I found a simple solution, I don't remember where I found it, anyway here is what I did.

<li><a href="index.html" title="home" class="active">Home</a></li><!---->
<li><a href="news.html" title="news">News</a></li><!---->
<li><a href="about.html" title="about">About Us</a></li><!---->
<li><a href="contact.html" title="contact">Contact Us</a></li>

You add a comment sign between each end of, and start of : "li" Then the horizontal space disappear. Hope that answer to the question Thanks

You should define the style on the td element like so:

<html>
<head>
    <style type="text/css">
        .bb
        {
            border-bottom: solid 1px black;
        }
    </style>
</head>
<body>
    <table>
        <tr>
            <td>
                Test 1
            </td>
        </tr>
        <tr>
            <td class="bb">
                Test 2
            </td>
        </tr>
    </table>
</body>
</html>

Please use the following query to list the tables in your DB.

select name from sys.Tables 

In Addition, you can add a where condition, to skip system generated tables and lists only user created table by adding type ='U'

Ex : select name from sys.Tables where type ='U'

Sometimes it takes longer to figure out the regex than to just write it out in python:

import string
s = "how much for the maple syrup? $20.99? That's ricidulous!!!"
for char in string.punctuation:
    s = s.replace(char, ' ')

If you need other characters you can change it to use a white-list or extend your black-list.

Sample white-list:

whitelist = string.letters + string.digits + ' '
new_s = ''
for char in s:
    if char in whitelist:
        new_s += char
    else:
        new_s += ' '

Sample white-list using a generator-expression:

whitelist = string.letters + string.digits + ' '
new_s = ''.join(c for c in s if c in whitelist)

I've had a lot of issues with developers checking in their console.() statements. And, I really don't like debugging Internet Explorer, despite the fantastic improvements of Internet Explorer 10 and Visual Studio 2012, etc.

So, I've overridden the console object itself... I've added a __localhost flag that only allows console statements when on localhost. I also added console.() functions to Internet Explorer (that displays an alert() instead).

// Console extensions...
(function() {
    var __localhost = (document.location.host === "localhost"),
        __allow_examine = true;

    if (!console) {
        console = {};
    }

    console.__log = console.log;
    console.log = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__log === "function") {
                console.__log(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert(msg);
            }
        }
    };

    console.__info = console.info;
    console.info = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__info === "function") {
                console.__info(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert(msg);
            }
        }
    };

    console.__warn = console.warn;
    console.warn = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__warn === "function") {
                console.__warn(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert(msg);
            }
        }
    };

    console.__error = console.error;
    console.error = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__error === "function") {
                console.__error(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert(msg);
            }
        }
    };

    console.__group = console.group;
    console.group = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__group === "function") {
                console.__group(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert("group:\r\n" + msg + "{");
            }
        }
    };

    console.__groupEnd = console.groupEnd;
    console.groupEnd = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__groupEnd === "function") {
                console.__groupEnd(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert(msg + "\r\n}");
            }
        }
    };

    /// <summary>

    /// <remarks>
    /// To enable __examine_() statements for sections/groups of code, type the

    /// in the code.
    /// </remarks>
    console.examine = function() {
        if (!__allow_examine) {
            return;
        }
        if (arguments.length > 0) {
            var obj = top["__examine_" + arguments[0]];
            if (obj && obj === true) {
                console.log(arguments.splice(0, 1));
            }
        }
    };
})();

Example use:

    console.log("hello");

Chrome/Firefox:

    prints hello in the console window.

Internet Explorer:

    displays an alert with 'hello'.

For those who look closely at the code, you'll discover the console.examine() function. I created this years ago so that I can leave debug code in certain areas around the product to help troubleshoot QA/customer issues. For instance, I would leave the following line in some released code:

    function doSomething(arg1) {
        // ...
        console.examine("someLabel", arg1);
        // ...
    }

And then from the released product, type the following into the console (or address bar prefixed with 'javascript:'):

    top.__examine_someLabel = true;

Then, I will see all of the logged console.examine() statements. It's been a fantastic help many times over.

on the server side in node.js I just added this and it worked. reactjs front end on my local machine can access api backend hosted on azure:

// Enables CORS
const cors = require('cors');
app.use(cors({ origin: true }));

One liner

In case you want to paste it in quickly...

document.cookie.split(";").forEach(function(c) { document.cookie = c.replace(/^ +/, "").replace(/=.*/, "=;expires=" + new Date().toUTCString() + ";path=/"); });

And the code for a bookmarklet :

javascript:(function(){document.cookie.split(";").forEach(function(c) { document.cookie = c.replace(/^ +/, "").replace(/=.*/, "=;expires=" + new Date().toUTCString() + ";path=/"); }); })();

This worked for me. Add sudo before python

curl https://bootstrap.pypa.io/get-pip.py |sudo python

The following will fit the image to 100% of container width while the height is constant. For local assets, use AssetImage

Container(
  width: MediaQuery.of(context).size.width,
  height: 100,
  decoration: BoxDecoration(
    image: DecorationImage(
      fit: BoxFit.fill,
      image: NetworkImage("https://picsum.photos/250?image=9"),
    ),
  ),
)

Image fill modes:

• Fill - Image is stretched

  fit: BoxFit.fill
  

  

  ---

• Fit Height - image kept proportional while making sure the full height of the image is shown (may overflow)

  fit: BoxFit.fitHeight
  

  

  ---

• Fit Width - image kept proportional while making sure the full width of the image is shown (may overflow)

  fit: BoxFit.fitWidth
  

  

  ---

• Cover - image kept proportional, ensures maximum coverage of the container (may overflow)

  fit: BoxFit.cover
  

  

  ---

• Contain - image kept proportional, minimal as possible, will reduce it's size if needed to display the entire image

  fit: BoxFit.contain
  

  

I came across this question when trying to check if a file existed on an FTP site or not. If the file doesn't exist there will be an error when trying to check its timestamp. But I want to make sure the error is not something else, by checking its type.

The Response property on WebException will be of type FtpWebResponse on which you can check its StatusCode property to see which FTP error you have.

Here's the code I ended up with:

    public static bool FileExists(string host, string username, string password, string filename)
    {
        // create FTP request
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + host + "/" + filename);
        request.Credentials = new NetworkCredential(username, password);

        // we want to get date stamp - to see if the file exists
        request.Method = WebRequestMethods.Ftp.GetDateTimestamp;

        try
        {
            FtpWebResponse response = (FtpWebResponse)request.GetResponse();
            var lastModified = response.LastModified;

            // if we get the last modified date then the file exists
            return true;
        }
        catch (WebException ex)
        {
            var ftpResponse = (FtpWebResponse)ex.Response;

            // if the status code is 'file unavailable' then the file doesn't exist
            // may be different depending upon FTP server software
            if (ftpResponse.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable)
            {
                return false;
            }

            // some other error - like maybe internet is down
            throw;
        }
    }

more generally, this could also look like this:

import multiprocessing
def chunks(l, n):
    for i in range(0, len(l), n):
        yield l[i:i + n]

numberOfThreads = 4


if __name__ == '__main__':
    jobs = []
    for i, param in enumerate(params):
        p = multiprocessing.Process(target=f, args=(i,param))
        jobs.append(p)
    for i in chunks(jobs,numberOfThreads):
        for j in i:
            j.start()
        for j in i:
            j.join()

Of course, that way is quite cruel (since it waits for every process in a junk until it continues with the next chunk). Still it works well for approx equal run times of the function calls.

Two things to keep in mind Content-Type and the Encoding

1) What if the file is css

if (/.(css)$/.test(path)) {
  res.writeHead(200, {'Content-Type': 'text/css'}); 
  res.write(data, 'utf8');
} 

2) What if the file is jpg/png

if (/.(jpg)$/.test(path)) {
  res.writeHead(200, {'Content-Type': 'image/jpg'});
  res.end(data,'Base64');
}

Above one is just a sample code to explain the answer and not the exact code pattern.

You need to escape the slashes as %2F.

Use <button> tag instead of <input type="button"..>. It is the advised practice in bootstrap 3.

http://getbootstrap.com/css/#buttons-tags

"Cross-browser rendering

As a best practice, we highly recommend using the <button> element whenever possible to ensure matching cross-browser rendering.

Among other things, there's a Firefox bug that prevents us from setting the line-height of <input>-based buttons, causing them to not exactly match the height of other buttons on Firefox."

At first run this command:

sudo mysql

and then you should check which authentication method of your MySQL user accounts use.So run this command

SELECT user,authentication_string,plugin,host FROM mysql.user;

now you can see something like this already :

+------------------+-------------------------------------------+-----------------------+-----------+
| user             | authentication_string                     | plugin                | host      |
+------------------+-------------------------------------------+-----------------------+-----------+
| root             |                                           | auth_socket           | localhost |
| mysql.session    | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys        | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *CC744277A401A7D25BE1CA89AFF17BF607F876FF | mysql_native_password | localhost |
+------------------+-------------------------------------------+-----------------------+-----------+

in the table that is in the above , you can see that all of your mysql users accounts status & if you have set a password for root account before you see mysql_native_password in plugin column instead auth_socket. All in all for change your root password you should run :

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

Be sure to change password to a strong password of your choosing. Then for reload your server to put your new changes into effect run this;

FLUSH PRIVILEGES;

So again check the authentication methods which has employed by your mysql , by this command:

SELECT user,authentication_string,plugin,host FROM mysql.user;

and now the output is :

+------------------+-------------------------------------------+-----------------------+-----------+
| user             | authentication_string                     | plugin                | host      |
+------------------+-------------------------------------------+-----------------------+-----------+
| root             | *3636DACC8616D997782ADD0839F92C1571D6D78F | mysql_native_password | localhost |
| mysql.session    | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys        | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *CC744277A401A7D25BE1CA89AFF17BF607F876FF | mysql_native_password | localhost |
+------------------+-------------------------------------------+-----------------------+-----------+

as you can see in the grant table your root account has mysql_native_password . now you can exit MYSQL shell

exit;

That's it.just you should restart mysql by sudo service mysql restart. Now you can login to mysql as a root account with your password easily.

Please, have a look on my implementation. You can wrap the following function into a service:

function(file, url) {
  var fd = new FormData();

  fd.append('file', file);

  return $http.post(url, fd, {
    transformRequest: angular.identity,
    headers: { 'Content-Type': undefined }
  });
}

Please notice, that file argument is a Blob. If you have base64 version of a file - it can be easily changed to Blob like so:

fetch(base64).then(function(response) {
  return response.blob(); 
}).then(console.info).catch(console.error);

You can try the following:

rtrim(number_format($coin->current_price,6),'0.')

Use a docstring:

A string literal that occurs as the first statement in a module, function, class, or method definition. Such a docstring becomes the __doc__ special attribute of that object.

All modules should normally have docstrings, and all functions and classes exported by a module should also have docstrings. Public methods (including the __init__ constructor) should also have docstrings. A package may be documented in the module docstring of the __init__.py file in the package directory.

String literals occurring elsewhere in Python code may also act as documentation. They are not recognized by the Python bytecode compiler and are not accessible as runtime object attributes (i.e. not assigned to __doc__ ), but two types of extra docstrings may be extracted by software tools:

1. String literals occurring immediately after a simple assignment at the top level of a module, class, or __init__ method are called "attribute docstrings".
2. String literals occurring immediately after another docstring are called "additional docstrings".

Please see PEP 258 , "Docutils Design Specification" [2] , for a detailed description of attribute and additional docstrings...

Unfortunately in Entity Framework 5 DbContext the issue is still not fixed.

I used this workaround (works with MSSQL 2012 but ANSI NULLS setting might be deprecated in any future MSSQL version).

public class Context : DbContext
{

    public Context()
        : base("name=Context")
    {
        this.Database.Connection.StateChange += Connection_StateChange;
    }

    void Connection_StateChange(object sender, System.Data.StateChangeEventArgs e)
    {
        // Set ANSI_NULLS OFF when any connection is opened. This is needed because of a bug in Entity Framework
        // that is not fixed in EF 5 when using DbContext.
        if (e.CurrentState == System.Data.ConnectionState.Open)
        {
            var connection = (System.Data.Common.DbConnection)sender;
            using (var cmd = connection.CreateCommand())
            {
                cmd.CommandText = "SET ANSI_NULLS OFF";
                cmd.ExecuteNonQuery();
            }
        }
    }
}

It should be noted that it is a dirty workaround but it is one that can be implemented very quickly and works for all queries.

PID   COMMAND      %CPU  
4306  top          5.6   
4304  java         745.7 
4296  locationd    0.0  

Set Application pool to classic .NET appool and make sure that Classic .Net apppool working on Classic managed piple line .

Change Iterator for each into for loop to solve.

And the Reason is:

The iterators returned by this class's iterator and listIterator methods are fail-fast: if the list is structurally modified at any time after the iterator is created, in any way except through the iterator's own remove or add methods, the iterator will throw a ConcurrentModificationException.

--Referred Java Docs.

$("#myid li").click(function() {
    alert(this.id); // id of clicked li by directly accessing DOMElement property
    alert($(this).attr('id')); // jQuery's .attr() method, same but more verbose
    alert($(this).html()); // gets innerHTML of clicked li
    alert($(this).text()); // gets text contents of clicked li
});

If you are talking about replacing the ID with something:

$("#myid li").click(function() {
    this.id = 'newId';

    // longer method using .attr()
    $(this).attr('id', 'newId');
});

Demo here. And to be fair, you should have first tried reading the documentation:

• http://api.jquery.com/category/selectors/
• http://api.jquery.com/category/events/
• http://api.jquery.com/attr/

The answer works very well, just to add a angular directive in case you are using angular like me:

app.directive('popover', ['$document', function($document) {
    return {
        restrict: 'EA',
        link: function(scope, elem, attrs) {
            $(document).ready(function() {
                $('[data-toggle="popover"]').popover();
            });

            elem.bind('click', function(e) {
                $('#notification').popover('toggle');
            })

            $('body').on('click', function (e) {
                //the 'is' for buttons that trigger popups
                //the 'has' for icons within a button that triggers a popup
                if (!elem.is(e.target)
                    && elem.has(e.target).length === 0
                    && $('.popover').has(e.target).length === 0) {
                    elem.popover('hide');
                }
            });
        }
    };
}]);

The html code:

<a popover tabindex="0" role="button"
   id="notification"
   data-toggle="popover" data-trigger="manual"
   data-container="body" data-placement="bottom"
   data-content="This is a popover">
   Popover button
</a>

It should have been as simple as use data-trigger='click focus', because according to bootstrap:

How popover is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space. manual cannot be combined with any other trigger.

However, use click and focus together doesn't work for me for unknown reason, instead I have to toggle it manually.

IMPORTANT - on ubuntu package docker is something entirely different ( avoid it ) :

issue following to view what if any packages you have mentioning docker

dpkg -l|grep docker

if only match is following then you do NOT have docker installed below is an unrelated package

docker - System tray for KDE3/GNOME2 docklet applications

if you see something similar to following then you have docker installed

 dpkg -l|grep docker

ii  docker-ce                                  5:19.03.13~3-0~ubuntu-focal         amd64        Docker: the open-source application container engine

NOTE - ubuntu package docker.io is not getting updates ( obsolete do NOT use )

Instead do this : install the latest version of docker on linux by executing the following:

  sudo curl -sSL https://get.docker.com/ | sh
# sudo curl -sSL https://test.docker.com | sh  # get dev pipeline version
  

here is a typical output ( ubuntu 16.04 )

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker stens

Remember that you will have to log out and back in for this to take effect!

Here is the underlying detailed install instructions which as you can see comes bundled into above technique ... Above one liner gives you same as :

https://docs.docker.com/engine/installation/linux/ubuntulinux/

Once installed you can see what docker packages were installed by issuing

dpkg -l|grep docker
ii  docker-ce                                  5:19.03.13~3-0~ubuntu-focal         amd64        Docker: the open-source application container engine
ii  docker-ce-cli                              5:19.03.13~3-0~ubuntu-focal         amd64        Docker CLI: the open-source application container engine

now Docker updates will get installed going forward when you issue

sudo apt-get update
sudo apt-get upgrade

take a look at

 ls -latr /etc/apt/sources.list.d/*docker*
-rw-r--r-- 1 root root 202 Jun 23 10:01 /etc/apt/sources.list.d/docker.list.save
-rw-r--r-- 1 root root  71 Jul  4 11:32 /etc/apt/sources.list.d/docker.list


cat /etc/apt/sources.list.d/docker.list

deb [arch=amd64] https://apt.dockerproject.org/repo ubuntu-xenial main

or more generally

cd /etc/apt
grep -r docker *
sources.list.d/docker.list:deb [arch=amd64] https://download.docker.com/linux/ubuntu focal test

I got this error message because I had a different user than what the repo expected in my git config.

This would obviously trigger the SSL Cert failures mentioned above.

Fixing to the correct user resolved this issue for me.

Just in case if you are using .BAT file as Windows Service, I would suggest to uninstall the Windows service and reinstall it again after changing the %JAVA_HOME% to point to the right Java version..

You may be using old version of Mysql but surely you can use

 DELETE FROM konta WHERE taken <> ''

But there are many other options available. You can try the following ones

DELETE * from konta WHERE strcmp(taken, '') <> 0;

DELETE * from konta where NOT (taken = '');

I know this is an older thread however I needed to write a function that returned the first blank row WITHIN a range. All of the code I found online actually searches the entire row (even the cells outside of the range) for a blank row. Data in ranges outside the search range was triggering a used row. This seemed to me to be a simple solution:

Function FirstBlankRow(ByVal rngToSearch As Range) As Long
   Dim R As Range
   Dim C As Range
   Dim RowIsBlank As Boolean

   For Each R In rngToSearch.Rows
      RowIsBlank = True
      For Each C In R.Cells
         If IsEmpty(C.Value) = False Then RowIsBlank = False
      Next C
      If RowIsBlank Then
         FirstBlankRow = R.Row
         Exit For
      End If
   Next R
End Function

You can use selectExpr to make it a little cleaner:

df.selectExpr("cast(year as int) as year", "upper(make) as make",
    "model", "comment", "blank")

I'd use inheritance. Especially if there are going to be more differences than number of holes. Especially if Gouda will need to have different set of members then Parmesan.

class Gouda(Cheese):
    def __init__(self):
        super(Gouda).__init__(num_holes=10)


class Parmesan(Cheese):
    def __init__(self):
        super(Parmesan).__init__(num_holes=15) 

If both data frames have the same column names then you should add one data frame inside ggplot() call and also name x and y values inside aes() of ggplot() call. Then add first geom_line() for the first line and add second geom_line() call with data=df2 (where df2 is your second data frame). If you need to have lines in different colors then add color= and name for eahc line inside aes() of each geom_line().

df1<-data.frame(x=1:10,y=rnorm(10))
df2<-data.frame(x=1:10,y=rnorm(10))

ggplot(df1,aes(x,y))+geom_line(aes(color="First line"))+
  geom_line(data=df2,aes(color="Second line"))+
  labs(color="Legend text")

Yet another CSS solution. Does not Work for popups that are bigger than the view port.

.modal-dialog {
    position: absolute;
    right: 0;
    left: 0;
    margin-top: 0;
    margin-bottom: 0; 
}
.modal.fade .modal-dialog {
    transition: top 0.4s ease-out;
    transform: translate(0, -50%);
    top: 0;
}
.modal.in .modal-dialog {
    transform: translate(0, -50%);
    top: 50%;
}

In .modal-dialog class overriding the position to absolute(from relative) and centering the content right:0, left: 0

In .modal.fade .modal-dialog , .modal.in .modal-dialog setting the transition animation over top rather than on translate.

margin-top moves the popup slightly below the center in case of small popup and in case of long popups, the modal is stuck with header. Hence margin-top:0, margin-bottom:0

Need to further refine it.

            Camera.getCameraInfo(i, info);
            if (info.facing == CameraInfo.CAMERA_FACING_FRONT) {
                Log.d(DEBUG_TAG, "Camera found");
                cameraId = i;
                break;
            }
        }
        return cameraId;
    }

    @Override
    protected void onPause() {
        if (camera != null) {
            camera.release();
            camera = null;
        }
        super.onPause();
    }

}

You can also make it this way :

<SeekBar
    android:id="@+id/redSeekBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:progressDrawable="@color/red"
    android:maxHeight="3dip"/>

Hope it will help!

Those are by no means the same. The first will simply send you to whatever URL you have assigned to window.location.href (in the same window you're currently in). The second makes a GET AJAX request.

Try this page: http://www.codebelt.com/jquery/open-new-browser-window-with-jquery-custom-size/

It gives a great example on how to open a new window*.

If you wish to use raw javascript then this is what you're looking for:

window.open(URL,name,specs,replace)

As seen in http://www.w3schools.com/jsref/met_win_open.asp

@BalusC is completely right, but If you still encounter this exception, it means that something you have done wrong. The most important information you will find is on the SO JSTL Tag Info page.

Basically this is a summary of what you need to do to deal with this exception.

1. Check the servlet version in web.xml: <web-app version="2.5">

2. Check if JSTL version is supported for this servlet version: Servlet version 2.5 uses JSTL 1.2 or Servlet version 2.4 uses JSTL 1.1

3. Your servlet container must have the appropriate library, or you must include it manually in your application. For example: JSTL 1.2 requires jstl-1.2.jar

What to do with Tomcat 5 or 6:

You need to include appropriate jar(s) into your WEB-INF/lib directory (it will work only for your application) or to the tomcat/lib (will work globally for all applications).

The last thing is a taglib in your jsp files. For JSTL 1.2 correct one is this:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

MOVE /-Y Source Destination

Note:/-y will make the announcement of yes/no for overwrite

So, let me give you sample code:

<div class="news">
Blah, blah, blah. I'm hidden.
</div>

<a class="trigger">Hide/Show News</a>

The link will be the trigger to show the div when clicked. So your Javascript will be:

$('.trigger').click(function() {
   $('.news').toggle();
});

You're almost always better off letting jQuery handle the styling for hiding and showing elements.

Edit: I see people above are recommending using .show and .hide for this. .toggle allows you to do both with just one effect. So that's cool.

Update

I've written a cross-browser range and selection library called Rangy that incorporates an improved version of the code I posted below. You can use the selection save and restore module for this particular question, although I'd be tempted to use something like @Nico Burns's answer if you're not doing anything else with selections in your project and don't need the bulk of a library.

Previous answer

You can use IERange (http://code.google.com/p/ierange/) to convert IE's TextRange into something like a DOM Range and use it in conjunction with something like eyelidlessness's starting point. Personally I would only use the algorithms from IERange that do the Range <-> TextRange conversions rather than use the whole thing. And IE's selection object doesn't have the focusNode and anchorNode properties but you should be able to just use the Range/TextRange obtained from the selection instead.

I will write this up fully at some point soon.

Usually you would be interested in also having some structure to your data in the receiving end:

json_encode($result)

This will preserve the array keys as well.

Do remember that json_encode only works on utf8 -encoded data.

You can also do it using reredirect (https://github.com/jerome-pouiller/reredirect/).

The command bellow redirects the outputs (standard and error) of the process PID to FILE:

reredirect -m FILE PID

The README of reredirect also explains other interesting features: how to restore the original state of the process, how to redirect to another command or to redirect only stdout or stderr.

The tool also provides relink, a script allowing to redirect the outputs to the current terminal:

relink PID
relink PID | grep usefull_content

(reredirect seems to have same features than Dupx described in another answer but, it does not depend on Gdb).

This variable below is final, so we can't change it's value once initialised. If we try to we'll get a compilation error...

final int variable = 123;

But if we create a variable like this, we can change it's value...

int variable = 123;
variable = 456;

But in Java 8, all variables are final by default. But the existence of the 2nd line in the code makes it non-final. So if we remove the 2nd line from the above code, our variable is now "effectively final"...

int variable = 123;

So.. Any variable that is assigned once and only once, is "effectively final".

Extracted from @Resord's comments above. This one worked for me and more closely inclined with the question.

$(this).parent().closest('.a');

Thanks

Redirect sys.stdout to an open file handle and then all printed output goes to a file:

import sys
filename  = open("outputfile",'w')
sys.stdout = filename
print "Anything printed will go to the output file"

For an ArrayAdapter, notifyDataSetChanged only works if you use the add(), insert(), remove(), and clear() on the Adapter.

When an ArrayAdapter is constructed, it holds the reference for the List that was passed in. If you were to pass in a List that was a member of an Activity, and change that Activity member later, the ArrayAdapter is still holding a reference to the original List. The Adapter does not know you changed the List in the Activity.

Your choices are:

1. Use the functions of the ArrayAdapter to modify the underlying List (add(), insert(), remove(), clear(), etc.)
2. Re-create the ArrayAdapter with the new List data. (Uses a lot of resources and garbage collection.)
3. Create your own class derived from BaseAdapter and ListAdapter that allows changing of the underlying List data structure.
4. Use the notifyDataSetChanged() every time the list is updated. To call it on the UI-Thread, use the runOnUiThread() of Activity. Then, notifyDataSetChanged() will work.

All those answers are good, but in fact, if you want to understand, the extension directory need to be right if you want all you uncommented extensions to work. Can write a physical or relative path like

extension_dir = "C:/myStack/php/ext"

or

extension_dir = "../../php/ext"

It's relative to the httpd.exe Apache web server (C:\myStack\apache\bin) But if you want it to work with Composer or anything you need the physical path because the cli mode doesn't use the web server !

Instant.now()

java.time

The accepted Answer by ppeterka is correct. Your abuse of the formatting pattern results in an erroneous display of data, while the internal value is always limited milliseconds.

The troublesome SimpleDateFormat and Date classes you are using are now legacy, supplanted by the java.time classes. The java.time classes handle nanoseconds resolution, much finer than the milliseconds limit of the legacy classes.

The equivalent to java.util.Date is java.time.Instant. You can even convert between them using new methods added to the old classes.

Instant instant = myJavaUtilDate.toInstant() ;

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Capture the current moment in UTC. Java 8 captures the current moment in milliseconds, while a new Clock implementation in Java 9 captures the moment in finer granularity, typically microseconds though it depends on the capabilities of your computer hardware clock & OS & JVM implementation.

Instant instant = Instant.now() ;

Generate a String in standard ISO 8601 format.

String output = instant.toString() ;

2018-02-02T00:28:02.487114Z

To generate strings in other formats, search Stack Overflow for DateTimeFormatter, already covered many times.

To adjust into a time zone other than UTC, use ZonedDateTime.

ZonedDateTime zdt = instant.atZone( ZoneId.of( "Pacific/Auckland" ) ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

More elegant approach:

echo "Memory usage for PID <>:"; for mem in {Private,Rss,Shared,Swap,Pss};do grep $mem /proc/<pid>/smaps | awk -v mem_type="$mem" '{i=i+$2} END {print mem_type,"memory usage:"i}' ;done

For some reason, some of the other methods don't work until the field has been focused/blured/changed, or a submit has been attempted... this works for me.

$("#formid").data('validator').element('#element').valid();

Had to dig through the jquery.validate script to find it...

#!/usr/bin/env python
#-*- coding: utf-8 -*-
u = u'moçambique'
print u.encode("utf-8")
print u

chmod +x test.py
./test.py
moçambique
moçambique

./test.py > output.txt
Traceback (most recent call last):
  File "./test.py", line 5, in <module>
    print u
UnicodeEncodeError: 'ascii' codec can't encode character 
u'\xe7' in position 2: ordinal not in range(128)

on shell works , sending to sdtout not , so that is one workaround, to write to stdout .

I made other approach, which is not run if sys.stdout.encoding is not define, or in others words , need export PYTHONIOENCODING=UTF-8 first to write to stdout.

import sys
if (sys.stdout.encoding is None):            
    print >> sys.stderr, "please set python env PYTHONIOENCODING=UTF-8, example: export PYTHONIOENCODING=UTF-8, when write to stdout." 
    exit(1)

so, using same example:

export PYTHONIOENCODING=UTF-8
./test.py > output.txt

will work

DirectoryInfo di = Directory.CreateDirectory(path);
Console.WriteLine("The directory was created successfully at {0}.",
    Directory.GetCreationTime(path));

This question has been answered quite thoroughly, but I'd like to add an answer that I hope is as simplified as possible, making the meaning of !! as simple to grasp as can be.

Because javascript has what are called "truthy" and "falsey" values, there are expressions that when evaluated in other expressions will result in a true or false condition, even though the value or expression being examined is not actually true or false.

For instance:

if (document.getElementById('myElement')) {
    // code block
}

If that element does in fact exist, the expression will evaluate as true, and the code block will be executed.

However:

if (document.getElementById('myElement') == true) {
    // code block
}

...will NOT result in a true condition, and the code block will not be executed, even if the element does exist.

Why? Because document.getElementById() is a "truthy" expression that will evaluate as true in this if() statement, but it is not an actual boolean value of true.

The double "not" in this case is quite simple. It is simply two nots back to back.

The first one simply "inverts" the truthy or falsey value, resulting in an actual boolean type, and then the second one "inverts" it back again to it's original state, but now in an actual boolean value. That way you have consistency:

if (!!document.getElementById('myElement')) {}

and

if (!!document.getElementById('myElement') == true) {}

will BOTH return true, as expected.

For those who reached this post for Answer:

This happens mainly because the InputStream the DOM parser is consuming is empty

So in what I ran across, there might be two situations:

1. The InputStream you passed into the parser has been used and thus emptied.
2. The File or whatever you created the InputStream from may be an empty file or string or whatever. The emptiness might be the reason caused the problem. So you need to check your source of the InputStream.

From all I have read you cannot do exactly what you want without javascript. If you float left before text

<div style="float:left;">widget</div> here is some CONTENT, etc.

Your content wraps as expected. But your widget is in the top left. If you instead put the float after the content

here is some CONTENT, etc. <div style="float:left;">widget</div>

Then your content will wrap the last line to the right of the widget if the last line of content can fit to the right of the widget, otherwise no wrapping is done. To make borders and backgrounds actually include the floated area in the previous example, most people add:

here is some CONTENT, etc. <div style="float:left;">widget</div><div style="clear:both;"></div>

In your question you are using bootstrap which just adds row-fluid::after { content: ""} which resolves the border/background issue.

Moving your content up will give you the one line wrap : http://jsfiddle.net/jJNPY/34/

  <div class="container-fluid">
  <div class="row-fluid">
    <div class="offset1 span8 pull-right">
    ... Widget 1...
    </div>
    .... a lot of content ....
    <div class="span8" style="margin-left: 0;">
    ... Widget 2...
    </div>


  </div>

</div><!--/.fluid-container-->

add list using

<asp:ListItem Value="United States" Text="Canada"></asp:ListItem>

and then try

DropDownList1.SelectedItem.Text

I found your mistake.

<asp:ListItem>United States</asp:ListItem> 

change this to

<asp:ListItem>United States1</asp:ListItem> 

Then you will got the actual value.

What was the issue is, there are two same values in your dropdown, when page postback, it take first value as selected and give the result accordingly. if you noticed when after postback United State Value is selected

function password_generator( len ) {
    var length = (len)?(len):(10);
    var string = "abcdefghijklmnopqrstuvwxyz"; //to upper 
    var numeric = '0123456789';
    var punctuation = '!@#$%^&*()_+~`|}{[]\:;?><,./-=';
    var password = "";
    var character = "";
    var crunch = true;
    while( password.length<length ) {
        entity1 = Math.ceil(string.length * Math.random()*Math.random());
        entity2 = Math.ceil(numeric.length * Math.random()*Math.random());
        entity3 = Math.ceil(punctuation.length * Math.random()*Math.random());
        hold = string.charAt( entity1 );
        hold = (password.length%2==0)?(hold.toUpperCase()):(hold);
        character += hold;
        character += numeric.charAt( entity2 );
        character += punctuation.charAt( entity3 );
        password = character;
    }
    password=password.split('').sort(function(){return 0.5-Math.random()}).join('');
    return password.substr(0,len);
}

console.log( password_generator() );

This generates a little more robust password that should pass any password strength test. eg: f1&d2?I4(h1&, C1^y1)j1@G2#, j2{h6%b5@R2)

If you intend on your application being available on a large range of devices, you should place your application icon into the different res/drawable... folders provided. In each of these folders, you should include a 48dp sized icon:

• drawable-ldpi (120 dpi, Low density screen) - 36px x 36px
• drawable-mdpi (160 dpi, Medium density screen) - 48px x 48px
• drawable-hdpi (240 dpi, High density screen) - 72px x 72px
• drawable-xhdpi (320 dpi, Extra-high density screen) - 96px x 96px
• drawable-xxhdpi (480 dpi, Extra-extra-high density screen) - 144px x 144px
• drawable-xxxhdpi (640 dpi, Extra-extra-extra-high density screen) - 192px x 192px

You may then define the icon in your AndroidManifest.xml file as such:

<application android:icon="@drawable/icon_name" android:label="@string/app_name" >
.... 
</application> 

In most cases, it really doesn't matter that much. Just pick a good size such as 4K or 16K and stick with it. If you're positive that this is the bottleneck in your application, then you should start profiling to find the optimal buffer size. If you pick a size that's too small, you'll waste time doing extra I/O operations and extra function calls. If you pick a size that's too big, you'll start seeing a lot of cache misses which will really slow you down. Don't use a buffer bigger than your L2 cache size.

$('li.menu.active')

is the simplest way. This will return all elements with both classes.

Or an already answered jQuery hasClass() - check for more than one class

If you have set up the CLI using eb init to your environment then it should be as simple as

eb ssh --setup which will allow you to create a new key pair or use an existing one if one exists.

You may also be able to just connect to the existing environment with eb use although I have not done that.

You could create a custom HashMap class for that in php. example as shown below containing the basic HashMap attributes such as get and set.

class HashMap{

        public $arr;

        function init() {

            function populate() {
                return null;
            }
            
            // change to 999 for efficiency
            $this->arr = array_map('populate', range(0, 9));

            return $this->arr;

        }
        
        function get_hash($key) {
            $hash = 0;

            for ($i=0; $i < strlen($key) ; $i++) { 
                $hash += ord($key[$i]);
            }
            
            // arr index starts from 0
            $hash_idx = $hash % (count($this->arr) - 1); 
            return $hash_idx;
            
        }

        function add($key, $value) {
            $idx = $this->get_hash($key);
            
            if ($this->arr[$idx] == null) {
                $this->arr[$idx] = [$value];
            } else{

                $found = false;

                $content = $this->arr[$idx];
                
                $content_idx = 0;
                foreach ($content as $item) {

                    // checking if they have same number of streams
                    if ($item == $value) {

                        $content[$content_idx] = [$value];
                        $found = true;
                        break;

                    }
                    
                    $content_idx++;
                }

                if (!$found) {
                    // $value is already an array
                    array_push($content, $value);

                    // updating the array
                    $this->arr[$idx] = $content;
                }

            }

            return $this->arr;

        }

        function get($key) {

            $idx = $this->get_hash($key);
            $content = $this->arr[$idx];

            foreach ($content as $item) {
                if ($item[1] == $key) {
                    return $item;
                    break;
                }
            }
                
        }

    }

Note that the performance of Enum.Parse() is awful, because it is implemented via reflection. (The same is true of Enum.ToString, which goes the other way.)

If you need to convert strings to Enums in performance-sensitive code, your best bet is to create a Dictionary<String,YourEnum> at startup and use that to do your conversions.

I don't think there is anything you can do to avoid what you are already doing, however, if you are building the table on the client with javascript, you can always add the style rules dynamically, so you can allow for any number of columns without cluttering up your css file with all those rules. See http://www.hunlock.com/blogs/Totally_Pwn_CSS_with_Javascript if you don't know how to do this.

Edit: For your "sticky" toggle, you should just append class names rather than replacing them. For instance, you can give it a class name of "hide2 hide3" etc. I don't think you really need the "show" classes, since that would be the default. Libraries like jQuery make this easy, but in the absence, a function like this might help:

var modifyClassName = function (elem, add, string) {
var s = (elem.className) ? elem.className : "";
var a = s.split(" ");
if (add) {
  for (var i=0; i<a.length; i++) {
      if (a[i] == string) {
          return;
          }
      }
  s += " " + string;
  }
else {
    s = "";
    for (var i=0; i<a.length; i++) {
        if (a[i] != string)
            s += a[i] + " "; 
        }
    }
elem.className = s;
}

You can define the drawables that are used for the background, and the switcher part like this:

<Switch
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:thumb="@drawable/switch_thumb"
    android:track="@drawable/switch_bg" />

Now you need to create a selector that defines the different states for the switcher drawable. Here the copies from the Android sources:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_enabled="false" android:drawable="@drawable/switch_thumb_disabled_holo_light" />
    <item android:state_pressed="true"  android:drawable="@drawable/switch_thumb_pressed_holo_light" />
    <item android:state_checked="true"  android:drawable="@drawable/switch_thumb_activated_holo_light" />
    <item                               android:drawable="@drawable/switch_thumb_holo_light" />
</selector>

This defines the thumb drawable, the image that is moved over the background. There are four ninepatch images used for the slider:

The deactivated version (xhdpi version that Android is using)
The pressed slider:
The activated slider (on state):
The default version (off state):

There are also three different states for the background that are defined in the following selector:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_enabled="false" android:drawable="@drawable/switch_bg_disabled_holo_dark" />
    <item android:state_focused="true"  android:drawable="@drawable/switch_bg_focused_holo_dark" />
    <item                               android:drawable="@drawable/switch_bg_holo_dark" />
</selector>

The deactivated version:
The focused version:
And the default version:

To have a styled switch just create this two selectors, set them to your Switch View and then change the seven images to your desired style.

2. by reference.

// passing parameters by reference . . .

void foo(const int &x) // x is a const reference
{
    x = 6;  
}

// passing parameters by const reference . . .

void foo(const int &x) // x is a const reference
{
    x = 6;  // compile error: a const reference cannot have its value changed!
}

3. by object.

class abc
{
    display()
    {
        cout<<"Class abc";
    }
}


// pass object by value
void show(abc S)
{
    cout<<S.display();
}

// pass object by reference
void show(abc& S)
{
    cout<<S.display();
}

The problem with rstrip is that it does not work in all cases (as I myself have seen few). Instead you can use - text= text.replace("\n"," ") this will remove all new line \n with a space.

Thanks in advance guys for your upvotes.

ExpandoObject is what are you looking for.

1. this is just simple here i'm appending html table into a div at the end
2. we can achieve this or any thing with a simple concept of calling a JavaScript function when we want (here on drop.)
3. In this example you can drag & drop any number of tables, new table will be added below the last table exists in the div other wise it will be the first table in the div.
4. here we can add text between tables or we can say the section where we drop tables is editable we can type text between tables.

Thanks... :)

This is Oracle bug, memory leak in shared_pool, most likely db managing lots of partitions. Solution: In my opinion patch not exists, check with oracle support. You can try with subpools or en(de)able AMM ...

Try using the excellent Datejs JavaScript date library (the original is no longer maintained so you may be interested in this actively maintained fork instead):

Date.today().add(-30).days(); // or...
Date.today().add({days:-30});

[Edit]

See also the excellent Moment.js JavaScript date library:

moment().subtract(30, 'days'); // or...
moment().add(-30, 'days');

Update your gradle version.

Go to your project level build.gradle file and make sure you are using the latest version of gradle.

Simple solution using itertools that preserves order (latter dicts have precedence)

# py2
from itertools import chain, imap
merge = lambda *args: dict(chain.from_iterable(imap(dict.iteritems, args)))

# py3
from itertools import chain
merge = lambda *args: dict(chain.from_iterable(map(dict.items, args)))

And it's usage:

>>> x = {'a':1, 'b': 2}
>>> y = {'b':10, 'c': 11}
>>> merge(x, y)
{'a': 1, 'b': 10, 'c': 11}

>>> z = {'c': 3, 'd': 4}
>>> merge(x, y, z)
{'a': 1, 'b': 10, 'c': 3, 'd': 4}

How old is Frank? I don't know (null).

How old is Shirley? I don't know (null).

Are Frank and Shirley the same age?

Correct answer should be "I don't know" (null), not "no", as Frank and Shirley might be the same age, we simply don't know.

ALTER TABLE <tablename> CHANGE COLUMN <colname> <colname> VARCHAR(65536);

You have to list the column name twice, even if you aren't changing its name.

Note that after you make this change, the data type of the column will be MEDIUMTEXT.

Miky D is correct, the MODIFY command can do this more concisely.

Re the MEDIUMTEXT thing: a MySQL row can be only 65535 bytes (not counting BLOB/TEXT columns). If you try to change a column to be too large, making the total size of the row 65536 or greater, you may get an error. If you try to declare a column of VARCHAR(65536) then it's too large even if it's the only column in that table, so MySQL automatically converts it to a MEDIUMTEXT data type.

mysql> create table foo (str varchar(300));
mysql> alter table foo modify str varchar(65536);
mysql> show create table foo;
CREATE TABLE `foo` (
  `str` mediumtext
) ENGINE=MyISAM DEFAULT CHARSET=latin1
1 row in set (0.00 sec)

I misread your original question, you want VARCHAR(65353), which MySQL can do, as long as that column size summed with the other columns in the table doesn't exceed 65535.

mysql> create table foo (str1 varchar(300), str2 varchar(300));
mysql> alter table foo modify str2 varchar(65353);
ERROR 1118 (42000): Row size too large. 
The maximum row size for the used table type, not counting BLOBs, is 65535. 
You have to change some columns to TEXT or BLOBs

There are several correct ways to display a down-pointing and upward-pointing triangle.

Method 1 : use decimal HTML entity

HTML :

▲
▼

Method 2 : use hexidecimal HTML entity

HTML :

▲
▼

Method 3 : use character directly

HTML :

?
?

Method 4 : use CSS

HTML :

<span class='icon-up'></span>
<span class='icon-down'></span>

CSS :

.icon-up:before {
    content: "\25B2";
}

.icon-down:before {
    content: "\25BC";
}

Each of these three methods should have the same output. For other symbols, the same three options exist. Some even have a fourth option, allowing you to use a string based reference (eg. ♥ to display ?).

You can use a reference website like Unicode-table.com to find which icons are supported in UNICODE and which codes they correspond with. For example, you find the values for the down-pointing triangle at http://unicode-table.com/en/25BC/.

Note that these methods are sufficient only for icons that are available by default in every browser. For symbols like ?,?,?,?,?,? or ?, this is far less likely to be the case. While it is possible to provide cross-browser support for other UNICODE symbols, the procedure is a bit more complicated.

If you want to know how to add support for less common UNICODE characters, see Create webfont with Unicode Supplementary Multilingual Plane symbols for more info on how to do this.

Background images

A totally different strategy is the use of background-images instead of fonts. For optimal performance, it's best to embed the image in your CSS file by base-encoding it, as mentioned by eg. @weasel5i2 and @Obsidian. I would recommend the use of SVG rather than GIF, however, is that's better both for performance and for the sharpness of your symbols.

This following code is the base64 for and SVG version of the icon :

/* size: 0.9kb */
url(data:image/svg+xml;base64,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

When to use background-images or fonts

For many use cases, SVG-based background images and icon fonts are largely equivalent with regards to performance and flexibility. To decide which to pick, consider the following differences:

SVG images

• They can have multiple colors
• They can embed their own CSS and/or be styled by the HTML document
• They can be loaded as a seperate file, embedded in CSS AND embedded in HTML
• Each symbol is represented by XML code or base64 code. You cannot use the character directly within your code editor or use an HTML entity
• Multiple uses of the same symbol implies duplication of the symbol when XML code is embedded in the HTML. Duplication is not required when embedding the file in the CSS or loading it as a seperate file
• You can not use color, font-size, line-height, background-color or other font related styling rules to change the display of your icon, but you can reference different components of the icon as shapes individually.
• You need some knowledge of SVG and/or base64 encoding
• Limited or no support in old versions of IE

Icon fonts

• An icon can have but one fill color, one background color, etc.
• An icon can be embedded in CSS or HTML. In HTML, you can use the character directly or use an HTML entity to represent it.
• Some symbols can be displayed without the use of a webfont. Most symbols cannot.
• Multiple uses of the same symbol implies duplication of the symbol when your character embedded in the HTML. Duplication is not required when embedding the file in the CSS.
• You can use color, font-size, line-height, background-color or other font related styling rules to change the display of your icon
• You need no special technical knowledge
• Support in all major browsers, including old versions of IE

Personally, I would recommend the use of background-images only when you need multiple colors and those color can't be achieved by means of color, background-color and other color-related CSS rules for fonts.

The main benefit of using SVG images is that you can give different components of a symbol their own styling. If you embed your SVG XML code in the HTML document, this is very similar to styling the HTML. This would, however, result in a web page that uses both HTML tags and SVG tags, which could significantly reduce the readability of a webpage. It also adds extra bloat if the symbol is repeated across multiple pages and you need to consider that old versions of IE have no or limited support for SVG.

The data would probably have been posted originally from a web form looking a bit like this (but probably much more complicated):

<form action="http://example.com" method="post">

  User login    <input name="user[login]"    /><br />
  User password <input name="user[password]" /><br />

  <input type="submit" />
</form>

If the method were "get" instead of "post", clicking the submit button would take you to a URL looking a bit like this:

http://example.com/?user%5Blogin%5D=username&user%5Bpassword%5D=123456

or:

http://example.com/?user[login]=username&user[password]=123456

The web server on the other end will likely take the user[login] and user[password] parameters, and make them into a user object with login and password fields containing those values.

If you need to know when the iframe is ready to manipulate, use an interval. In this case I "ping" the content every 250 ms and if there's any content inside target iframe, stop the "ping" and do something.

var checkIframeLoadedInterval = setInterval( checkIframeLoaded, 250 );

function checkIframeLoaded() {
    var iframe_content = $('iframe').contents();

    if (iframe_content.length > 0) {
        clearInterval(checkIframeLoadedInterval);

        //Apply styles to the button
        setTimeout(function () {
            //Do something inside the iframe 
            iframe_content.find("body .whatever").css("background-color", "red");
        }, 100); //100 ms of grace time
    }
}

You can add this to your _Layout.cshtml:

@using MyProj.ViewModels;
...
    @if (TempData["UserMessage"] != null)
    {
        var message = (MessageViewModel)TempData["UserMessage"];
        <div class="alert @message.CssClassName" role="alert">
            <button type="button" class="close" data-dismiss="alert" aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
            <strong>@message.Title</strong>
            @message.Message
        </div>
    }

Then if you want to throw an error message in your controller:

    TempData["UserMessage"] = new MessageViewModel() { CssClassName = "alert-danger  alert-dismissible", Title = "Error", Message = "This is an error message" };

MessageViewModel.cs:

public class MessageViewModel
    {
        public string CssClassName { get; set; }
        public string Title { get; set; }
        public string Message { get; set; }
    }

Note: Using Bootstrap 4 classes.

$("input[name='mygroup'][value='5']").attr("checked", true);

Here is my workaround,
In your example you can add a third element with "same styles" of .one & .two elements, but without the absolute position and with hidden visibility:

HTML

<article>
   <div class="one"></div>
   <div class="two"></div>
   <div class="three"></div>
</article>

CSS

.three{
    height: 30px;
    z-index: -1;
    visibility: hidden;
}

As mentioned by jfriend00 you should not expose your server structure. You could copy your project dependency files to something like public/scripts. You can do this very easily with dep-linker like this:

var DepLinker = require('dep-linker');
DepLinker.copyDependenciesTo('./public/scripts')
// Done

Well for Ubuntu 14.04 I was getting that error just for mcrypt:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20121212/mcrypt.ini' - /usr/lib/php5/20121212/mcrypt.ini: cannot open shared object file: No such file or directory in Unknown on line 0

If you have a closer look at the error, php is looking for mcrypt.ini and not for mcrypt.so at that location. I just copy mcrypt.so to mcrypt.ini and that's it, the warning is gone and the extension now is properly installed. It might look a bit dirty but it worked!

Error:(30, 13) Failed to resolve: com.google.firebase:firebase-auth:9.6.1

If you ever get this error and you are using Android studio 2.2 that comes with firebase component integrated in it which has libraries version 9.6.0 by default and you are adding the latest dependencies like 9.6.1 . You might need to downgrade com.google.firebase:firebase-auth:9.6.1 to com.google.firebase:firebase-auth:9.6.0

Or check the library version of your pre-installed firebase and make sure it is of the same version with the new library you are trying to add or added to your project.

I'm using excel 2010 and below VBA code worked fine for a Form Button. It removes the assigned macro from the button and assign in next command.

To disable:

ActiveSheet.Shapes("Button Name").OnAction = Empty
ActiveSheet.Shapes("Button Name").DrawingObject.Font.ColorIndex = 16

To enable:

ActiveSheet.Shapes("Button Name").OnAction = ActiveWorkbook.Name & "!Macro function Name with _Click"
ActiveSheet.Shapes("Button Name").DrawingObject.Font.ColorIndex = 1

Pls note "ActiveWorkbook.Name" stays as it is. Do not insert workbook name instead of "Name".

The macros defined in <inttypes.h> are the most correct way to print values of types uint32_t, uint16_t, and so forth -- but they're not the only way.

Personally, I find those macros difficult to remember and awkward to use. (Given the syntax of a printf format string, that's probably unavoidable; I'm not claiming I could have come up with a better system.)

An alternative is to cast the values to a predefined type and use the format for that type.

Types int and unsigned int are guaranteed by the language to be at least 16 bits wide, and therefore to be able to hold any converted value of type int16_t or uint16_t, respectively. Similarly, long and unsigned long are at least 32 bits wide, and long long and unsigned long long are at least 64 bits wide.

For example, I might write your program like this (with a few additional tweaks):

#include <stdio.h>
#include <stdint.h>
#include <netinet/in.h>  

int main(void)
{
    uint32_t a=12, a1;
    uint16_t b=1, b1;
    a1 = htonl(a);
    printf("%lu---------%lu\n", (unsigned long)a, (unsigned long)a1);
    b1 = htons(b);
    printf("%u-----%u\n", (unsigned)b, (unsigned)b1);
    return 0;
}

One advantage of this approach is that it can work even with pre-C99 implementations that don't support <inttypes.h>. Such an implementation most likely wouldn't have <stdint.h> either, but the technique is useful for other integer types.

My answer is similar but different, there are a few ways to achieve toggling effect. I guess it depends on your circumstance. This may not be the best way for you in the end.

The missing piece you've been looking for is to create an if statement. This allows for you to toggle your text.

More on if statements here.

JSFiddle: http://jsfiddle.net/8u2jF/

Javascript:

var status = "less";

function toggleText()
{
    var text="Here is some text that I want added to the HTML file";

    if (status == "less") {
        document.getElementById("textArea").innerHTML=text;
        document.getElementById("toggleButton").innerText = "See Less";
        status = "more";
    } else if (status == "more") {
        document.getElementById("textArea").innerHTML = "";
        document.getElementById("toggleButton").innerText = "See More";
        status = "less"
    }
}

You could just create an array of the correct size up-front and fill it:

frames = np.empty((480, 640, 3, 100))

for k in xrange(nframes):
    frames[:,:,:,k] = cv2.imread('frame_{}.jpg'.format(k))

if the frames were individual jpg file that were named in some particular way (in the example, frame_0.jpg, frame_1.jpg, etc).

Just a note, you might consider using a (nframes, 480,640,3) shaped array, instead.

The displayed error

after that import react

Finally import react-dom

if error is react is not define,please add ==>import React from 'react';

if error is reactDOM is not define,please add ==>import ReactDOM from 'react-dom';

It looks like you have a certificate in DER format instead of PEM. This is why it works correctly when you provide the -inform PEM command line argument (which tells openssl what input format to expect).

It's likely that your private key is using the same encoding. It looks as if the openssl rsa command also accepts a -inform argument, so try:

openssl rsa -text -in file.key -inform DER

A PEM encoded file is a plain-text encoding that looks something like:

-----BEGIN RSA PRIVATE KEY-----
MIGrAgEAAiEA0tlSKz5Iauj6ud3helAf5GguXeLUeFFTgHrpC3b2O20CAwEAAQIh
ALeEtAIzebCkC+bO+rwNFVORb0bA9xN2n5dyTw/Ba285AhEA9FFDtx4VAxMVB2GU
QfJ/2wIRANzuXKda/nRXIyRw1ArE2FcCECYhGKRXeYgFTl7ch7rTEckCEQDTMShw
8pL7M7DsTM7l3HXRAhAhIMYKQawc+Y7MNE4kQWYe
-----END RSA PRIVATE KEY-----

While DER is a binary encoding format.

Update

Sometimes keys are distributed in PKCS#8 format (which can be either PEM or DER encoded). Try this and see what you get:

openssl pkcs8 -in file.key -inform der

Simple way without using Regex:

public static String getOnlyNumerics(String str) {
    if (str == null) {
        return null;
    }
    StringBuffer strBuff = new StringBuffer();
    char c;
    for (int i = 0; i < str.length() ; i++) {
        c = str.charAt(i);
        if (Character.isDigit(c)) {
            strBuff.append(c);
        }
    }
    return strBuff.toString();
}

What you actually created with:

MyType[] list = []

Was fixed size array (not list) with size of 0. You can create fixed size array of size for example 4 with:

MyType[] array = new MyType[4]

But there's no add method of course.

If you create list with def it's something like creating this instance with Object (You can read more about def here). And [] creates empty ArrayList in this case.

So using def list = [] you can then append new items with add() method of ArrayList

list.add(new MyType())

Or more groovy way with overloaded left shift operator:

list << new MyType()

One way is that In case of Session Expire, in every action you have to check its session and if it is null then redirect to Login page.

But this is very hectic method To over come this you need to create your own ActionFilterAttribute which will do this, you just need to add this attribute in every action method.

Here is the Class which overrides ActionFilterAttribute.

public class SessionExpireFilterAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            HttpContext ctx = HttpContext.Current;

            // check if session is supported
            CurrentCustomer objCurrentCustomer = new CurrentCustomer();
            objCurrentCustomer = ((CurrentCustomer)SessionStore.GetSessionValue(SessionStore.Customer));
            if (objCurrentCustomer == null)
            {
                // check if a new session id was generated
                filterContext.Result = new RedirectResult("~/Users/Login");
                return;
            }

            base.OnActionExecuting(filterContext);
        }
    }

Then in action just add this attribute like so:

[SessionExpire]
public ActionResult Index()
{
     return Index();
}

This will do you work.

mktemp is probably the most versatile, especially if you plan to work with the file for a while.

You can also use a process substitution operator <() if you only need the file temporarily as input to another command, e.g.:

$ diff <(echo hello world) <(echo foo bar)

The answer to run valgrind --tool=callgrind is not quite complete without some options. We usually do not want to profile 10 minutes of slow startup time under Valgrind and want to profile our program when it is doing some task.

So this is what I recommend. Run program first:

valgrind --tool=callgrind --dump-instr=yes -v --instr-atstart=no ./binary > tmp

Now when it works and we want to start profiling we should run in another window:

callgrind_control -i on

This turns profiling on. To turn it off and stop whole task we might use:

callgrind_control -k

Now we have some files named callgrind.out.* in current directory. To see profiling results use:

kcachegrind callgrind.out.*

I recommend in next window to click on "Self" column header, otherwise it shows that "main()" is most time consuming task. "Self" shows how much each function itself took time, not together with dependents.

This works at the moment (Oct. 2016), but I can't guarantee how long it will last:

For unix systems only:

>>> import datetime
>>> d = datetime.date(2011,01,01)
>>> d.strftime("%s")  # <-- THIS IS THE CODE YOU WANT
'1293832800'

Note 1: dizzyf observed that this applies localized timezones. Don't use in production.

Note 2: Jakub Narebski noted that this ignores timezone information even for offset-aware datetime (tested for Python 2.7).

For what it's worth, I've run into this on what was previously working code. I had added SELECT statements in a trigger for debug testing and forgot to remove them. Entity Framework / MVC doesnt play nice when other stuff is output to the "grid". Make sure to check for any rogue queries and remove them.

Updated:

This answer is simpler than my answer: https://stackoverflow.com/a/21718540/541862

Original answer:

# Create a backup of master branch
git branch backup_master

# Point master to '56e05fce' and
# make working directory the same with '56e05fce'
git reset --hard 56e05fce

# Point master back to 'backup_master' and
# leave working directory the same with '56e05fce'.
git reset --soft backup_master

# Now working directory is the same '56e05fce' and
# master points to the original revision. Then we create a commit.
git commit -a -m "Revert to 56e05fce"

# Delete unused branch
git branch -d backup_master

The two commands git reset --hard and git reset --soft are magic here. The first one changes the working directory, but it also changes head (the current branch) too. We fix the head by the second one.

This is a modified version of Tim Post's method; I used /dev/tty instead of /dev/stdout. I don't know why it doesn't work with stdout (which is a link to /proc/self/fd/1):

freopen("log.txt","w",stdout);
...
...
freopen("/dev/tty","w",stdout);

By using /dev/tty the output is redirected to the terminal from where the app was launched.

Hope this info is useful.

After looking at all the suggestions here, I've discovered a few things which I hope will be useful to others in my position:

1. hop is right to point me back at /etc/init.d/functions: the daemon function already allows you to set an alternate user:

   daemon --user=my_user my_cmd &>/dev/null &
   

   This is implemented by wrapping the process invocation with runuser - more on this later.

2. Jonathan Leffler is right: there is setuid in Python:

   import os
   os.setuid(501) # UID of my_user is 501
   

   I still don't think you can setuid from inside a JVM, however.

3. Neither su nor runuser gracefully handle the case where you ask to run a command as the user you already are. E.g.:

   [my_user@my_host]$ id
   uid=500(my_user) gid=500(my_user) groups=500(my_user)
   [my_user@my_host]$ su my_user -c "id"
   Password: # don't want to be prompted!
   uid=500(my_user) gid=500(my_user) groups=500(my_user)
   

To workaround that behaviour of su and runuser, I've changed my init script to something like:

if [[ "$USER" == "my_user" ]]
then
    daemon my_cmd &>/dev/null &
else
    daemon --user=my_user my_cmd &>/dev/null &
fi

Thanks all for your help!

Sure: svn rm the unwanted folder, and commit.

To avoid this situation in the future, I would follow the recommended layout for SVN projects:

• Put your code in the /someproject/trunk folder (or just /trunk if you want to put only one project in the repository)
• Created branches as /someproject/branches/somebranch
• Put tags under /someproject/tags

Now when you check out a working copy, be sure to check out only trunk or some individual branch. Don't check everything out in one huge working copy containing all branches.¹

¹_{Unless you know what you're doing, in which case you know how to create shallow working copies.}

I am not pro in Java but your problem can be solved by "blockingqueue" if you use it wisely.

Try to retrieve a chunk of records first, process them, and iterate the process until you complete your processing. This may help you to get rid of the OutOfMemory Exceptions.

var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'

<p>Please click in the following {{link}} to verify the account</p>

function renderHTML(templatePath: string, object) {
    const template = fileSystem.readFileSync(path.join(Application.staticDirectory, templatePath + '.html'), 'utf8');
    return template.match(/\{{(.*?)\}}/ig).reduce((acc, binding) => {
        const property = binding.substring(2, binding.length - 2);
        return `${acc}${template.replace(/\{{(.*?)\}}/, object[property])}`;
    }, '');
}

renderHTML(templateName, { link: 'SomeLink' })

for sure you can improve the reading template function to read as stream and compose the bytes by line to make it more efficient

I was getting &oacute; in $mail->Subject /w PHPMailer.

So for me the complete solution is:

// Your Subject with tildes. Example.
$someSubjectWithTildes = 'Subscripción España';

$mailer->CharSet = 'UTF-8';
$mailer->Encoding = 'quoted-printable';
$mailer->Subject = html_entity_decode($someSubjectWithTildes);

Hope it helps.

Dictionary<,> is the equivalent. While it doesn't have a Get(...) method, it does have an indexed property called Item which you can access in C# directly using index notation:

class Test {
  Dictionary<int,String> entities;

  public String getEntity(int code) {
    return this.entities[code];
  }
}

If you want to use a custom key type then you should consider implementing IEquatable<> and overriding Equals(object) and GetHashCode() unless the default (reference or struct) equality is sufficient for determining equality of keys. You should also make your key type immutable to prevent weird things happening if a key is mutated after it has been inserted into a dictionary (e.g. because the mutation caused its hash code to change).

i was also getting this error, remove oracle folder from

C:\Program Files (x86)\Oracle\Inventory

and

C:\Program Files\Oracle\Inventory

Also remove all component of oracle other version (which you had already in your system).

Go to services and remove all oracle component and delete old client from

C:\app\username\product\11.2.0\client_1\

There are two ways to load jQuery in your application:

1) Add jQuery from your own site.

For this, you need to add jQuery reference in <Head> section of your page with correct src path:

<script src="script/jquery.js" type="text/javascript"></script>

But this create an additional load to your server for download a file to client

2) ther other way to load jQuery from any other server like Google, Microsoft or jQuery itself.

As stated here:

it provides several advantages.

1. You always use the latest jQuery framework.
2. It reduces the load from your server.
3. It saves bandwidth. jQuery framework will load faster from these CDN.
4. The most important benefit is it will be cached, if the user has visited any site which is using jQuery framework from any of these CDN.

Here is the link by which you can load jQuery from Microsoft. Follow this url, it may be helpful.

Here is one to sort various columns in a csv file by numeric and dictionary order, columns 5 and after as dictionary order

~/test>sort -t, -k1,1n -k2,2n -k3,3d -k4,4n -k5d  sort.csv
1,10,b,22,Ga
2,2,b,20,F
2,2,b,22,Ga
2,2,c,19,Ga
2,2,c,19,Gb,hi
2,2,c,19,Gb,hj
2,3,a,9,C

~/test>cat sort.csv
2,3,a,9,C
2,2,b,20,F
2,2,c,19,Gb,hj
2,2,c,19,Gb,hi
2,2,c,19,Ga
2,2,b,22,Ga
1,10,b,22,Ga

Note the -k1,1n means numeric starting at column 1 and ending at column 1. If I had done below, it would have concatenated column 1 and 2 making 1,10 sorted as 110

~/test>sort -t, -k1,2n -k3,3 -k4,4n -k5d  sort.csv
2,2,b,20,F
2,2,b,22,Ga
2,2,c,19,Ga
2,2,c,19,Gb,hi
2,2,c,19,Gb,hj
2,3,a,9,C
1,10,b,22,Ga
