I know this question is a bit old but i would suggest to use some cachebraking hash in the url of the javascript. This works perfectly in production as well as during development because you can have both infinite cache times and intant updates when changes occur.

Lets assume you have a javascript file /js/script.min.js, but in the referencing html/php file you do not use the actual path but:

<script src="/js/script.<?php echo md5(filemtime('/js/script.min.js')); ?>.min.js"></script>

So everytime the file is changed, the browser gets a different url, which in turn means it cannot be cached, be it locally or on any proxy inbetween.

To make this work you need nginx to rewrite any request to /js/script.[0-9a-f]{32}.min.js to the original filename. In my case i use the following directive (for css also):

location ~* \.(css|js)$ {
                expires max;
                add_header Pragma public;
                etag off;
                add_header Cache-Control "public";
                add_header Last-Modified "";
                rewrite  "^/(.*)\/(style|script)\.min\.([\d\w]{32})\.(js|css)$" /$1/$2.min.$4 break;
        }

I would guess that the filemtime call does not even require disk access on the server as it should be in linux's file cache. If you have doubts or static html files you can also use a fixed random value (or incremental or content hash) that is updated when your javascript / css preprocessor has finished or let one of your git hooks change it.

In theory you could also use a cachebreaker as a dummy parameter (like /js/script.min.js?cachebreak=0123456789abcfef), but then the file is not cached at least by some proxies because of the "?".

CentOS7 + VM

Ive made it with:

1. Gparted-live extend the volume
2. pvresize -v /dev/sda2
3. lvresize -r -l+100%FREE centos/root

SBT solution stated above did not work for me. What worked for me is excluding slf4j-log4j12

//dependencies with exclusions_x000D_
libraryDependencies ++= Seq(_x000D_
    //depencies_x000D_
).map(_.exclude("org.slf4j","slf4j-log4j12"))

I haven't used it yet but I would take a look at http://www.zoneminder.com/ The documentation explains you can install it on a modest machine with linux and use IP cameras for remote recording.

try this:

$('.chzn-choices input').autocomplete({
  source: function( request, response ) {
    $.ajax({
      url: "/change/name/autocomplete/"+request.term+"/",
      dataType: "json",
      beforeSend: function(){$('ul.chzn-results').empty();},
      success: function( data ) {
        response( $.map( data, function( item ) {
          $('ul.chzn-results').append('<li class="active-result">' + item.name + '</li>');
        }));
      }
    });
  }
});

H.264 is a new standard for video compression which has more advanced compression methods than the basic MPEG-4 compression. One of the advantages of H.264 is the high compression rate. It is about 1.5 to 2 times more efficient than MPEG-4 encoding. This high compression rate makes it possible to record more information on the same hard disk.
The image quality is also better and playback is more fluent than with basic MPEG-4 compression. The most interesting feature however is the lower bit-rate required for network transmission.
So the 3 main advantages of H.264 over MPEG-4 compression are:
- Small file size for longer recording time and better network transmission.
- Fluent and better video quality for real time playback
- More efficient mobile surveillance application

H264 is now enshrined in MPEG4 as part 10 also known as AVC

Refer to: http://www.velleman.eu/downloads/3/h264_vs_mpeg4_en.pdf

Hope this helps.

For iPhone it works if you add also playsinline so:

<video width="320" height="240" autoplay loop muted playsinline>
  <source src="movie.mp4" type="video/mp4" />
</video>

Some time This Code Not worked proper

Same-origin policy

https://en.wikipedia.org/wiki/Same-origin_policy

https://en.wikipedia.org/wiki/Cross-origin_resource_sharing

problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is [CORS][1]. 

Ref : https://superuser.com/questions/773719/how-do-all-of-these-save-video-from-youtube-services-work/773998#773998

url_encoded_fmt_stream_map // traditional: contains video and audio stream
adaptive_fmts              // DASH: contains video or audio stream

Each of these is a comma separated array of what I would call "stream objects". Each "stream object" will contain values like this

url  // direct HTTP link to a video
itag // code specifying the quality
s    // signature, security measure to counter downloading

Each URL will be encoded so you will need to decode them. Now the tricky part.

YouTube has at least 3 security levels for their videos

unsecured // as expected, you can download these with just the unencoded URL
s         // see below
RTMPE     // uses "rtmpe://" protocol, no known method for these

The RTMPE videos are typically used on official full length movies, and are protected with SWF Verification Type 2. This has been around since 2011 and has yet to be reverse engineered.

The type "s" videos are the most difficult that can actually be downloaded. You will typcially see these on VEVO videos and the like. They start with a signature such as

AA5D05FA7771AD4868BA4C977C3DEAAC620DE020E.0F421820F42978A1F8EAFCDAC4EF507DB5 Then the signature is scrambled with a function like this

function mo(a) {
  a = a.split("");
  a = lo.rw(a, 1);
  a = lo.rw(a, 32);
  a = lo.IC(a, 1);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 44);
  return a.join("")
}

This function is dynamic, it typically changes every day. To make it more difficult the function is hosted at a URL such as

http://s.ytimg.com/yts/jsbin/html5player-en_US-vflycBCEX.js

this introduces the problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is CORS. With CORS, s.ytimg.com could add this header

Access-Control-Allow-Origin: http://www.youtube.com

and it would allow the JavaScript to download from www.youtube.com. Of course they do not do this. A workaround for this workaround is to use a CORS proxy. This is a proxy that responds with the following header to all requests

Access-Control-Allow-Origin: *

So, now that you have proxied your JS file, and used the function to scramble the signature, you can use that in the querystring to download a video.

You have to use

<iframe title="YouTube video player" width="480" height="390" src="http://www.youtube.com/embed/zGPuazETKkI?autoplay=1" frameborder="0" allowfullscreen></iframe>

?autoplay=1

and not

&autoplay=1

its the first URL param so its added with a ?

Unless you do some kind of post-processing work, the video will never be better than the original frames. Also just like a flip-book, if you have a big "jump" between keyframes it will look funny. You generally need enough "tweens" in between the keyframes to give smooth animation. HTH

This is a really late response, but I came up with this to solve a particular problem I had with DiskInternals LinuxReader appending '.efs_ntfs' to files that it saved to non-NTFS (FAT32) directories :

@echo off
REM %1 is the directory to recurse through and %2 is the file extension to remove
for /R "%1" %%f in (*.%2) do (
    REM Path (sans drive) is given by %%~pf ; drive is given by %%~df
    REM file name (sans ext) is given by %%~nf ; to 'rename' files, move them
    copy "%%~df%%~pf%%~nf.%2" "%%~df%%~pf%%~nf"
    echo "%%~df%%~pf%%~nf.%2" copied to "%%~df%%~pf%%~nf"
echo.
)
pause

The Miro video converter does a beautiful job and is drag-n-drop. http://www.mirovideoconverter.com/

BTW it's FREE and also very good for mobile device encoding.

That is how I prevented direct access from URL to my ini files. Paste the following code in .htaccess file on root. (no need to create extra folder)

<Files ~ "\.ini$">
  Order allow,deny
  Deny from all
</Files>

my settings.ini file is on the root, and without this code is accessible www.mydomain.com/settings.ini

Maybe some hidden characters are messing with your json, try this:

$json = utf8_encode($yourString);
$data = json_decode($json);

Following solutions will first read the whole content to memory before writing it to disc (for more i/o efficient solutions look at the other answers).

You can use open-uri, which is a one liner

require 'open-uri'
content = open('http://example.com').read

Or by using net/http

require 'net/http'
File.write("file_name", Net::HTTP.get(URI.parse("http://url.com")))

In addition, if you have a FileInfo fi, you can simply do:

string ext = fi.Extension;

and it'll hold the extension of the file (note: it will include the ., so a result of the above could be: .jpg .txt, and so on....

Had this problem recently with converting nasty WMV into Final Cut Pro X for editing. Flow player can do it but it leaves a water mark, so I fiddled a bit with ffmpeg till I got something going.

First install ffmpeg - I used brew install ffmpeg Obviously you need brew installed first, google that bit.

Next I wrote a simple command line script with the following content - you can substitute the $1 for an input / output file or just create a shell script file... vi convert.sh Paste.

echo "Pass one" ffmpeg -y -i "$1" -c:v libx264 -preset medium -b:v 1555k -pass 1 -c:a libfaac -b:a 256k -f mp4 /dev/null && echo "Pass two" ffmpeg -i "$1" -c:v libx264 -preset medium -b:v 1555k -pass 2 -c:a libfaac -b:a 256k "$1.mp4"

Then to convert your video... sh convert.sh myvideofile.wmv If all went well you should see a new file called myvideofile.wmv.mp4.

Hope that works for you.

To all interested:

The "Coding for fun" book's chapter 4 "InnerTube: Download, Convert, and Sync YouTube Videos" deals with the topic. The code and discussion are at http://www.c4fbook.com/InnerTube.

[PLEASE BEWARE] While the overall concepts are valid some years after the publication, non-documented details of the youtube internals the project relies on can have changed (see the comment at the bottom of the page behind the second link).

@Michiel is correct to create a button but the code for ActionScript 3 it is a little different - where movieClipName is the name of your 'button'.

movieClipName.addEventListener(MouseEvent.CLICK, callLink);
function callLink:void {
  var url:String = "http://site";
  var request:URLRequest = new URLRequest(url);
  try {
    navigateToURL(request, '_blank');
  } catch (e:Error) {
    trace("Error occurred!");
  }
}

I'm not sure about the parameters(mpaction, format), if they are specified for the amazonaws page or ##.##.

Try to urlencode() the url.

Just use

File.Copy(filepath, "\\\\192.168.1.28\\Files");

A windows fileshare exposed via a UNC path is treated as part of the file system, and has nothing to do with the web.

The credentials used will be that of the ASP.NET worker process, or any impersonation you've enabled. If you can tweak those to get it right, this can be done.

You may run into problems because you are using the IP address instead of the server name (windows trust settings prevent leaving the domain - by using IP you are hiding any domain details). If at all possible, use the server name!

If this is not on the same windows domain, and you are trying to use a different domain account, you will need to specify the username as "[domain_or_machine]\[username]"

If you need to specify explicit credentials, you'll need to look into coding an impersonation solution.

Here's an example: http://duncan99.wordpress.com/2011/10/08/google-maps-api-infowindows/

marker.addListener('mouseover', function() {
    infowindow.open(map, this);
});

// assuming you also want to hide the infowindow when user mouses-out
marker.addListener('mouseout', function() {
    infowindow.close();
});

You can inspect elements of a website in your Android device using Chrome browser.

Open your Chrome browser and go to the website you want to inspect.

Go to the address bar and type "view-source:" before the "HTTP" and reload the page.

The whole elements of the page will be shown.

For HttpClient-4.1 using TLSv1.2, code would go something like this:

        SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, null, new SecureRandom());
        SSLSocketFactory sf = new SSLSocketFactory(sslContext);
        Scheme httpsScheme = new Scheme("https", 443, sf);
        SchemeRegistry schemeRegistry = new SchemeRegistry();
        schemeRegistry.register(httpsScheme);
        ClientConnectionManager cm =  new        SingleClientConnManager(schemeRegistry);
        HttpClient client = new DefaultHttpClient(cm);

       // Use client to make the connection and get the results.

Use sender ID & API Key generated here: http://developers.google.com instead (browse for Google Cloud Messaging first and follow the instruction).

PJL is right. I have used his suggestion and this is what i have done:

1. defined global variables for fragment:

   private final Object attachingActivityLock = new Object();

   private boolean syncVariable = false;

2. implemented

@Override
public void onAttach(Activity activity) {
  super.onAttach(activity);
  synchronized (attachingActivityLock) {
      syncVariable = true;
      attachingActivityLock.notifyAll();
  }
}

3 . I wrapped up my function, where I need to call getActivity(), in thread, because if it would run on main thread, i would block the thread with the step 4. and onAttach() would never be called.

    Thread processImage = new Thread(new Runnable() {

        @Override
        public void run() {
            processImage();
        }
    });
    processImage.start();

4 . in my function where I need to call getActivity(), I use this (before the call getActivity())

    synchronized (attachingActivityLock) {
        while(!syncVariable){
            try {
                attachingActivityLock.wait();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }

If you have some UI updates, remember to run them on UI thread. I need to update ImgeView so I did:

image.post(new Runnable() {

    @Override
    public void run() {
        image.setImageBitmap(imageToShow);
    }
});

If there is any chance that you will need to search for empty strings,

    a['Names'].str.contains('') 

will NOT work, as it will always return True.

Instead, use

    if '' in a["Names"].values

to accurately reflect whether or not a string is in a Series, including the edge case of searching for an empty string.

For put method we have:

const putMethod = {
 method: 'PUT', // Method itself
 headers: {
  'Content-type': 'application/json; charset=UTF-8' // Indicates the content 
 },
 body: JSON.stringify(someData) // We send data in JSON format
}

// make the HTTP put request using fetch api
fetch(url, putMethod)
.then(response => response.json())
.then(data => console.log(data)) // Manipulate the data retrieved back, if we want to do something with it
.catch(err => console.log(err)) // Do something with the error

Example for someData, we can have some input fields or whatever you need:

const someData = {
 title: document.querySelector(TitleInput).value,
 body: document.querySelector(BodyInput).value
}

And in our data base will have this in json format:

{
 "posts": [
   "id": 1,
   "title": "Some Title", // what we typed in the title input field
   "body": "Some Body", // what we typed in the body input field
 ]
}

For delete method we have:

const deleteMethod = {
 method: 'DELETE', // Method itself
 headers: {
  'Content-type': 'application/json; charset=UTF-8' // Indicates the content 
 },
 // No need to have body, because we don't send nothing to the server.
}
// Make the HTTP Delete call using fetch api
fetch(url, deleteMethod) 
.then(response => response.json())
.then(data => console.log(data)) // Manipulate the data retrieved back, if we want to do something with it
.catch(err => console.log(err)) // Do something with the error

In the url we need to type the id of the of deletion: https://www.someapi/id

The escaped hex reference of  is \f066.

content: "\f066";

Remove "values" when you're appending a group of rows, and remove the extra parentheses. You can avoid the circular reference by using an alias for avg(CurrencyColumn) (as you did in your example) or by not using an alias at all.

If the column names are the same in both tables, your query would be like this:

INSERT INTO Table2 (LongIntColumn, Junk)
SELECT LongIntColumn, avg(CurrencyColumn) as CurrencyColumn1
FROM Table1
GROUP BY LongIntColumn;

And it would work without an alias:

INSERT INTO Table2 (LongIntColumn, Junk)
SELECT LongIntColumn, avg(CurrencyColumn)
FROM Table1
GROUP BY LongIntColumn;

You might want to chose based on what is widely available. I had the same question and here are the results of my limited research.

actions in Vuex are asynchronous. The only way to let the calling function (initiator of action) to know that an action is complete - is by returning a Promise and resolving it later.

Here is an example: myAction returns a Promise, makes a http call and resolves or rejects the Promise later - all asynchronously

actions: {
    myAction(context, data) {
        return new Promise((resolve, reject) => {
            // Do something here... lets say, a http call using vue-resource
            this.$http("/api/something").then(response => {
                // http success, call the mutator and change something in state
                resolve(response);  // Let the calling function know that http is done. You may send some data back
            }, error => {
                // http failed, let the calling function know that action did not work out
                reject(error);
            })
        })
    }
}

Now, when your Vue component initiates myAction, it will get this Promise object and can know whether it succeeded or not. Here is some sample code for the Vue component:

export default {
    mounted: function() {
        // This component just got created. Lets fetch some data here using an action
        this.$store.dispatch("myAction").then(response => {
            console.log("Got some data, now lets show something in this component")
        }, error => {
            console.error("Got nothing from server. Prompt user to check internet connection and try again")
        })
    }
}

As you can see above, it is highly beneficial for actions to return a Promise. Otherwise there is no way for the action initiator to know what is happening and when things are stable enough to show something on the user interface.

And a last note regarding mutators - as you rightly pointed out, they are synchronous. They change stuff in the state, and are usually called from actions. There is no need to mix Promises with mutators, as the actions handle that part.

Edit: My views on the Vuex cycle of uni-directional data flow:

If you access data like this.$store.state["your data key"] in your components, then the data flow is uni-directional.

The promise from action is only to let the component know that action is complete.

The component may either take data from promise resolve function in the above example (not uni-directional, therefore not recommended), or directly from $store.state["your data key"] which is unidirectional and follows the vuex data lifecycle.

The above paragraph assumes your mutator uses Vue.set(state, "your data key", http_data), once the http call is completed in your action.

Try this code:

SELECT * FROM table WHERE column REGEXP '^[A-Za-z0-9]+$'

This makes sure that all characters match.

if you get this error

Gradle: 
FAILURE: Could not determine which tasks to execute.
* What went wrong:
Task 'assemble' not found in root project 'MyProject'.
* Try:
Run gradle tasks to get a list of available tasks.

You need to edit your Projects .iml file. not the one under src. the one that is like myappProject.iml' delete the whole component name = facetmanager

<module external.system.id="GRADLE" type="JAVA_MODULE" version="4">
<component name="FacetManager">
...remove this element and everything inside such as <facet> elements...
</component>
<component name="NewModuleRootManager" inherit-compiler-output="true">
...keep this part...
</component

I believe fill is the fastest way to do this.

a = np.empty(10)
a.fill(7)

You should also always avoid iterating like you are doing in your example. A simple a[:] = v will accomplish what your iteration does using numpy broadcasting.

You must create a new date object and set it as minDate when you initialize the datepickers

<label for="from">From</label> <input type="text" id="from" name="from"/> <label for="to">to</label> <input type="text" id="to" name="to"/>

var dateToday = new Date();
var dates = $("#from, #to").datepicker({
    defaultDate: "+1w",
    changeMonth: true,
    numberOfMonths: 3,
    minDate: dateToday,
    onSelect: function(selectedDate) {
        var option = this.id == "from" ? "minDate" : "maxDate",
            instance = $(this).data("datepicker"),
            date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, selectedDate, instance.settings);
        dates.not(this).datepicker("option", option, date);
    }
});

Edit - from your comment now it works as expected http://jsfiddle.net/nicolapeluchetti/dAyzq/1/

To add to Xavi's answer, Paul Irish's github David Desandro's gitgub offers a function called imagesLoaded() that works on the same principles, and gets around the problem of some browser's cached images not firing the .load() event (with clever original_src -> data_uri -> original_src switching).

It's is widely used and updated regularly, which contributes to it being the most robust solution to the problem, IMO.

If the return in the try block is reached, it transfers control to the finally block, and the function eventually returns normally (not a throw).

If an exception occurs, but then the code reaches a return from the catch block, control is transferred to the finally block and the function eventually returns normally (not a throw).

In your example, you have a return in the finally, and so regardless of what happens, the function will return 34, because finally has the final (if you will) word.

Although not covered in your example, this would be true even if you didn't have the catch and if an exception were thrown in the try block and not caught. By doing a return from the finally block, you suppress the exception entirely. Consider:

public class FinallyReturn {
  public static final void main(String[] args) {
    System.out.println(foo(args));
  }

  private static int foo(String[] args) {
    try {
      int n = Integer.parseInt(args[0]);
      return n;
    }
    finally {
      return 42;
    }
  }
}

If you run that without supplying any arguments:

$ java FinallyReturn

...the code in foo throws an ArrayIndexOutOfBoundsException. But because the finally block does a return, that exception gets suppressed.

This is one reason why it's best to avoid using return in finally.

The error message you are getting is a result of Git still thinking that you have not resolved the merge conflicts. In fact, you already have, but you need to tell Git that you have done this by adding the resolved files to the index.

This has the side effect that you could actually just add the files without resolving the conflicts, and Git would still think that you have. So you should be diligent in making sure that you have really resolved the conflicts. You could even run the build and test the code before you commit.

npm install bootstrap --save

and add relevent files into angular.json file under the style property for css files and under scripts for JS files.

 "styles": [
  "../node_modules/bootstrap/dist/css/bootstrap.min.css",
   ....
]

for me the default is Shift + Tab,

you can select the text you want, press Shift + Tab to shift everything on the left, selecting all and pressing Tab shifts everything to the right.

var json1=["Chennai","Bangalore"];
var json2=["TamilNadu","Karanataka"];

finaljson=json1.concat(json2);

Workaround:

t = time()
t2 = time(t.hour+1, t.minute, t.second, t.microsecond)

You can also omit the microseconds, if you don't need that much precision.

This kind of code perhaps should work for You

In your implementation

std::ostream& operator<<(std::ostream& stream,

    matrix.print(stream); //assuming you define print for matrix

I have had this issue before, and solve it using the following config.

Since git 2.3.1, you can put https://your.domain after http to indicate the following certificate is only for it.

TextView is used to display text on Android application. By default, TextView displays text on one line and if long, TextView will automatically display with more lines to display its text in the most logical way.

Android developers can create a new line on TextView both in programming and syntax. Android developers can create multi-line TextView without dividing text into multiple lines according to android: minLines properties. Create layout.xml

I know this is an old question but you can use:

array_push($data, array($category => $question));

This will push the array onto the end of your current array. Or if you are just trying to add single values to the end of your array, not more arrays then you can use this:

array_push($data,$question);

Similar to Alexandrin's answer, but using $state rather than $route:

(From JimTheDev's SO answer here.)

$scope.reloadState = function() {
   $state.go($state.current, {}, {reload: true});
}

<a ng-click="reloadState()" ... 

COPY <all> <the> <things> <last-arg-is-destination>

But here is an important excerpt from the docs:

If you have multiple Dockerfile steps that use different files from your context, COPY them individually, rather than all at once. This ensures that each step’s build cache is only invalidated (forcing the step to be re-run) if the specifically required files change.

https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#add-or-copy

It's easier using Array.filter:

var unique = arr.filter(function(elem, index, self) {
    return index === self.indexOf(elem);
})

My guess is it's not in your path.
in bash, try:
echo $PATH
and
sudo which nginx
And see if the folder containing nginx is also in your $PATH variable.
If not, either add the folder to your path environment variable, or create an alias (and put it in your .bashrc) ooor your could create a link i guess.
or sudo nginx -v if you just want that...

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

Here's the function I personally use - I simply derived it from the function I used for sha-1 hashing:

  int n;
  SHA256_CTX c;
  unsigned char digest[ SHA256_DIGEST_LENGTH ];
  char *out = (char*) malloc( 33 );

  SHA256_Init( &c );

  while ( length > 0 ) {
    if ( length > 512 ) SHA256_Update( &c, str, 512 );
    else SHA256_Update( &c, str, length );

    length -= 512;
    str += 512;
  }

  SHA256_Final ( digest, &c );

  for ( n = 0; n < SHA256_DIGEST_LENGTH; ++n )
    snprintf( &( out[ n*2 ] ), 16*2, "%02x", (unsigned int) digest[ n ] );

  return out;
}

    $_timezone = date_default_timezone_get();

Here is a simple solution based on threads which:

• works on both Linux and Windows (not relying on select).
• reads both stdout and stderr asynchronouly.
• doesn't rely on active polling with arbitrary waiting time (CPU friendly).
• doesn't use asyncio (which may conflict with other libraries).
• runs until the child process terminates.

sys.stderr.write("That's an error\n")

def enqueue_stream(stream, queue, type):
    for line in iter(stream.readline, b''):
        queue.put(str(type) + line.decode('utf-8'))
    stream.close()


def enqueue_process(process, queue):
    process.wait()
    queue.put('x')


p = subprocess.Popen('python printer.py', stdout=subprocess.PIPE, stderr=subprocess.PIPE)
q = queue.Queue()
to = threading.Thread(target=enqueue_stream, args=(p.stdout, q, 1))
te = threading.Thread(target=enqueue_stream, args=(p.stderr, q, 2))
tp = threading.Thread(target=enqueue_process, args=(p, q))
te.start()
to.start()
tp.start()

while True:
    line = q.get()
    if line[0] == 'x':
        break
    if line[0] == '2':  # stderr
        sys.stdout.write("\033[0;31m")  # ANSI red color
    sys.stdout.write(line[1:])
    if line[0] == '2':
        sys.stdout.write("\033[0m")  # reset ANSI code
    sys.stdout.flush()

tp.join()
to.join()
te.join()

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

It is fast. Try it:

DELETE FROM YourTABLE
FROM (SELECT TOP XX PK FROM YourTABLE) tbl
WHERE YourTABLE.PK = tbl.PK

Replace YourTABLE by table name, XX by a number, for example 1000, pk is the name of the primary key field of your table.

Instead of using --no-optional every single time, we can just add it to npm or yarn config.

For Yarn, there is a default no-optional config, so we can just edit that:

yarn config set ignore-optional true

For npm, there is no default config set, so we can create one:

npm config set ignore-optional true

For python2 you can use this code before csv_writer.writerows(rows)
This code will NOT convert integers to utf-8 strings

def encode_rows_to_utf8(rows):
    encoded_rows = []
    for row in rows:
        encoded_row = []
        for value in row:
            if isinstance(value, basestring):
                value = unicode(value).encode("utf-8")
            encoded_row.append(value)
        encoded_rows.append(encoded_row)
    return encoded_rows

I think the answer to this question pretty much sums up the problem with your question.

If what you want to do is find out whether a given host will accept TCP connections on port 80, you can do this:

$host = '193.33.186.70'; 
$port = 80; 
$waitTimeoutInSeconds = 1; 
if($fp = fsockopen($host,$port,$errCode,$errStr,$waitTimeoutInSeconds)){   
   // It worked 
} else {
   // It didn't work 
} 
fclose($fp);

For anything other than TCP it will be more difficult (although since you specify 80, I guess you are looking for an active HTTP server, so TCP is what you want). TCP is sequenced and acknowledged, so you will implicitly receive a returned packet when a connection is successfully made. Most other transport protocols (commonly UDP, but others as well) do not behave in this manner, and datagrams will not be acknowledged unless the overlayed Application Layer protocol implements it.

The fact that you are asking this question in this manner tells me you have a fundamental gap in your knowledge on Transport Layer protocols. You should read up on ICMP and TCP, as well as the OSI Model.

Also, here's a slightly cleaner version to ping to hosts.

// Function to check response time
function pingDomain($domain){
    $starttime = microtime(true);
    $file      = fsockopen ($domain, 80, $errno, $errstr, 10);
    $stoptime  = microtime(true);
    $status    = 0;

    if (!$file) $status = -1;  // Site is down
    else {
        fclose($file);
        $status = ($stoptime - $starttime) * 1000;
        $status = floor($status);
    }
    return $status;
}

I cannot get a match using Xpather, but the following worked for me with plain XML and XSL files in Microsoft's XML Notepad:

<xsl:value-of select="count(//td[text()='&nbsp;'])" />

The value returned is 1, which is the correct value in my test case.

However, I did have to declare nbsp as an entity within my XML and XSL using the following:

<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#160;"> ]>

I'm not sure if that helps you, but I was able to actually find nbsp using an XPath expression.

Edit: My code sample actually contains the characters ' ' but the JavaScript syntax highlight converts it to the space character. Don't be mislead!

I've just solved the problem on an Android 4.0.2 device (GN) and the only version working for this device/version was similar to the first 5-starred with CALL_PHONE permission and the answer:

Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:123456789"));
startActivity(callIntent);

With any other solution i got the ActivityNotFoundException on this device/version. How about the older versions? Would someone give feedback?

You can do it like this:

list.add(1, object1)
list.add(2, object3)
list.add(2, object2)

After you add object2 to position 2, it will move object3 to position 3.

If you want object3 to be at position3 all the time I'd suggest you use a HashMap with position as key and object as a value.

What you are probably really wanting to do here is use the union operator like this:

(select ID from Logo where AccountID = 1 and Rendered = 'True')
  union
  (select ID from Design where AccountID = 1 and Rendered = 'True')
  order by ID limit 0, 51

Here's the docs for it https://dev.mysql.com/doc/refman/5.0/en/union.html

You installed PHP IntelliSense extension, and this error because of it.
So if you want to fix this problem go to this menu:
File -> Preferences -> Settings
Now you can see 2 window. In the right window add below codes:

{
    "php.validate.executablePath": "C:\\wamp64\\bin\\php\\php7.0.4\\php.exe",
    "php.executablePath": "C:\\wamp64\\bin\\php\\php7.0.4\\php.exe"
}

Just like below image.



NOTICE: This address C:\\wamp64\\bin\\php\\php7.0.4\\php.exe is my php7.exe file address. Replace this address with own php7.exe.

Here is another way:

• Browse someone's commit history (Click commits which is next to branch to see the whole commit history)

• Click the commit that with the person's username because there might be so many of them

• Then you should see the web address has a hash concatenated to the URL. Add .patch to this commit URL

• You will probably see the person's email address there

Example: https://github.com/[username]/[reponame]/commit/[hash].patch

Below is a fast approach to remove a potential '\n' from a string saved by fgets().
It uses strlen(), with 2 tests.

char buffer[100];
if (fgets(buffer, sizeof buffer, stdin) != NULL) {

  size_t len = strlen(buffer);
  if (len > 0 && buffer[len-1] == '\n') {
    buffer[--len] = '\0';
  }

Now use buffer and len as needed.

This method has the side benefit of a len value for subsequent code. It can be easily faster than strchr(Name, '\n'). Ref YMMV, but both methods work.

buffer, from the original fgets() will not contain in "\n" under some circumstances:
A) The line was too long for buffer so only char preceding the '\n' is saved in buffer. The unread characters remain in the stream.
B) The last line in the file did not end with a '\n'.

If input has embedded null characters '\0' in it somewhere, the length reported by strlen() will not include the '\n' location.

Some other answers' issues:

1. strtok(buffer, "\n"); fails to remove the '\n' when buffer is "\n". From this answer - amended after this answer to warn of this limitation.

2. The following fails on rare occasions when the first char read by fgets() is '\0'. This happens when input begins with an embedded '\0'. Then buffer[len -1] becomes buffer[SIZE_MAX] accessing memory certainly outside the legitimate range of buffer. Something a hacker may try or found in foolishly reading UTF16 text files. This was the state of an answer when this answer was written. Later a non-OP edited it to include code like this answer's check for "".

   size_t len = strlen(buffer);
   if (buffer[len - 1] == '\n') {  // FAILS when len == 0
     buffer[len -1] = '\0';
   }
   

3. sprintf(buffer,"%s",buffer); is undefined behavior: Ref. Further, it does not save any leading, separating or trailing whitespace. Now deleted.

4. [Edit due to good later answer] There are no problems with the 1 liner buffer[strcspn(buffer, "\n")] = 0; other than performance as compared to the strlen() approach. Performance in trimming is usually not an issue given code is doing I/O - a black hole of CPU time. Should following code need the string's length or is highly performance conscious, use this strlen() approach. Else the strcspn() is a fine alternative.

Permission name is CASE-SENSITIVE

In case somebody will struggle with same issue, it is case sensitive statement, so wrong case means your application won't get the permission.

WRONG

<uses-permission android:name="ANDROID.PERMISSION.INTERNET" />

CORRECT

<uses-permission android:name="android.permission.INTERNET" />

This issue may happen ie. on autocomplete in IDE

You can have multiple <context:property-placeholder /> elements instead of explicitly declaring multiple PropertiesPlaceholderConfigurer beans.

For those using asyncio, an easy way is to use asyncio.wait_for():

async def my_loop():
    res = False
    while not res:
        res = await do_something()

await asyncio.wait_for(my_loop(), 10)

Terminating a connection open with vagrant ssh will show the address, so a dummy or empty command can be executed:

$ vagrant ssh -c ''
Connection to 192.168.121.155 closed.

For those of you who want to execute a side-effect only if an optional is absent

i.e. an equivalent of ifAbsent() or ifNotPresent() here is a slight modification to the great answers already provided.

myOptional.ifPresentOrElse(x -> {}, () -> {
  // logic goes here
})

I created dummy sample for Google Maps v2 Android with Kotlin and AndroidX

You can find complete project here: github-link

MainActivity.kt

class MainActivity : AppCompatActivity() {

val position = LatLng(-33.920455, 18.466941)

override fun onCreate(savedInstanceState: Bundle?) {

    setContentView(R.layout.activity_main)

    with(mapView) {
        // Initialise the MapView
        onCreate(null)
        // Set the map ready callback to receive the GoogleMap object
        getMapAsync{
            MapsInitializer.initialize(applicationContext)
            setMapLocation(it)
        }

    with(map) {
        moveCamera(CameraUpdateFactory.newLatLngZoom(position, 13f))
        addMarker(MarkerOptions().position(position))
        mapType = GoogleMap.MAP_TYPE_NORMAL

Actually The documentation shows that you can use XMLHttpRequest().send() to simply send multiform data in case jquery sucks

Just extends your Adapter like below

public class RankingAdapter extends AnimatedRecyclerView<RankingAdapter.ViewHolder> 

And add super method to onBindViewHolder

@Override
    public void onBindViewHolder(ViewHolder holder, final int position) {
        super.onBindViewHolder(holder, position);

It's automate way to create animated adapter like "Basheer AL-MOMANI"

import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.view.ViewGroup;
import android.view.animation.Animation;
import android.view.animation.ScaleAnimation;

import java.util.Random;

/**
 * Created by eliaszkubala on 24.02.2017.
 */
public class AnimatedRecyclerView<T extends RecyclerView.ViewHolder> extends RecyclerView.Adapter<T> {


    @Override
    public T onCreateViewHolder(ViewGroup parent, int viewType) {
        return null;
    }

    @Override
    public void onBindViewHolder(T holder, int position) {
        setAnimation(holder.itemView, position);
    }

    @Override
    public int getItemCount() {
        return 0;
    }

    protected int mLastPosition = -1;

    protected void setAnimation(View viewToAnimate, int position) {
        if (position > mLastPosition) {
            ScaleAnimation anim = new ScaleAnimation(0.0f, 1.0f, 0.0f, 1.0f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
            anim.setDuration(new Random().nextInt(501));//to make duration random number between [0,501)
            viewToAnimate.startAnimation(anim);
            mLastPosition = position;
        }
    }

}

You can specify it in your IDE. For example, for Eclipse in Run Configurations ? VM arguments. You can enter -Xmx800m -Xms500m as

./main.go (in package main)
./a/a.go (in package a)
./a/b.go (in package a)

in this case:
main.go import "./a"

It can call the function in the a.go and b.go,that with first letter caps on.

In many cases, you have an interface and pass along an object that implements it. Dialogs for example have the OnClickListener.

Just as a random example:

// The callback interface
interface MyCallback {
    void callbackCall();
}

// The class that takes the callback
class Worker {
   MyCallback callback;

   void onEvent() {
      callback.callbackCall();
   }
}

// Option 1:

class Callback implements MyCallback {
   void callbackCall() {
      // callback code goes here
   }
}

worker.callback = new Callback();

// Option 2:

worker.callback = new MyCallback() {

   void callbackCall() {
      // callback code goes here
   }
};

I probably messed up the syntax in option 2. It's early.

import { Component, ElementRef, OnInit } from '@angular/core';

@Component({
  selector:'display',
  template:`
   <input (input)="updateName($event.target.value)">
   <p> My name : {{ myName }}</p>
  `
})
class DisplayComponent implements OnInit {
  constructor(public element: ElementRef) {
    this.element.nativeElement // <- your direct element reference 
  }
  ngOnInit() {
    var el = this.element.nativeElement;
    console.log(el);
  }
  updateName(value) {
    // ...
  }
}

Example updated to work with the latest version

The easiest way is to use Resource Manager

Then you can select each density

And after importing you can see the 6 different versions of this image

If you're using Bootstrap 3, you can use the Glyphicons.

.slick-prev:before, .slick-next:before {
    font-family: "Glyphicons Halflings", "slick", sans-serif;
    font-size: 40px;
}

.slick-prev:before { content: "\e257"; }
.slick-next:before { content: "\e258"; }

Although this is almost certainly not the OPs issue, you can also get Unable to establish SSL connection from wget if you're behind a proxy and don't have HTTP_PROXY and HTTPS_PROXY environment variables set correctly. Make sure to set HTTP_PROXY and HTTPS_PROXY to point to your proxy.

This is a common situation if you work for a large corporation.

A good way to create Public/Global variables is to treat the Form like a class object and declare properties and use Public Property Get [variable] to access property/method. Also you might need to reference or pass a Reference to the instantiated Form module. You will get errors if you call methods to forms/reports that are closed.
Example: pass Me.Form.Module.Parent into sub/function not inside form.

Option Compare Database 
Option Explicit
''***********************************''
' Name: Date: Created Date Author: Name 
' Current Version: 1.0
' Called by: 
''***********************************''
' Notes: Explain Who what when why... 
' This code Example requires properties to be filled in 
''***********************************''
' Global Variables
Public GlobalData As Variant
''***********************************''
' Private Variables
Private ObjectReference As Object
Private ExampleVariable As Variant
Private ExampleData As Variant
''***********************************''
' Public properties
Public Property Get ObjectVariable() As Object
   Set ObjectVariable = ObjectReference
End Property 
Public Property Get Variable1() As Variant 
  'Recommend using variants to avoid data errors
  Variable1 = ExampleVariable
End property
''***********************************''
' Public Functions that return values
Public Function DataReturn (Input As Variant) As Variant
   DataReturn = ExampleData + Input
End Function 
''***********************************''
' Public Sub Routines
Public Sub GlobalMethod() 
   'call local Functions/Subs outside of form
   Me.Form.Refresh
End Sub
''***********************************''
' Private Functions/Subs used not visible outside 
''***********************************''
End Code

So in the other module you would be able to access:

Public Sub Method1(objForm as Object)
   'read/write data value
   objForm.GlobalData
   'Get object reference (need to add Public Property Set to change reference object)
   objForm.ObjectVariable
   'read only (needs Public property Let to change value)
   objForm.Variable1
   'Gets result of function with input
   objForm.DataReturn([Input])
   'runs sub/function from outside of normal scope
   objForm.GlobalMethod
End Sub

If you use Late Binding like I do always check for Null values and objects that are Nothing before attempting to do any processing.

This worked for me:

[XmlInclude(typeof(BankPayment))]
[Serializable]
public abstract class Payment { }    

[Serializable]
public class BankPayment : Payment {} 

[Serializable]
public class Payments : List<Payment>{}

XmlSerializer serializer = new XmlSerializer(typeof(Payments), new Type[]{typeof(Payment)});

If you know the maxValue (can be easily done if another iteration of the elements is not an issue) of the matrix, I find the following code more effective and generic.

    int numDigits = (int) Math.log10(maxValue) + 1;
    if (numDigits <= 1) {
        numDigits = 2;
    }
    StringBuffer buf = new StringBuffer();
    for (int i = 0; i < matrix.length; i++) {
        int[] row = matrix[i];
        for (int j = 0; j < row.length; j++) {
            int block = row[j];
            buf.append(String.format("%" + numDigits + "d", block));
            if (j >= row.length - 1) {
                buf.append("\n");
            }
        }
    }
    return buf.toString();

What you're looking at is an expression-bodied member not a lambda expression.

When the compiler encounters an expression-bodied property member, it essentially converts it to a getter like this:

public int MaxHealth
{
    get
    {
        return Memory[Address].IsValid ? Memory[Address].Read<int>(Offs.Life.MaxHp) : 0;
    }
}

(You can verify this for yourself by pumping the code into a tool called TryRoslyn.)

Expression-bodied members - like most C# 6 features - are just syntactic sugar. This means that they don’t provide functionality that couldn't otherwise be achieved through existing features. Instead, these new features allow a more expressive and succinct syntax to be used

As you can see, expression-bodied members have a handful of shortcuts that make property members more compact:

• There is no need to use a return statement because the compiler can infer that you want to return the result of the expression
• There is no need to create a statement block because the body is only one expression
• There is no need to use the get keyword because it is implied by the use of the expression-bodied member syntax.

I have made the final point bold because it is relevant to your actual question, which I will answer now.

The difference between...

// expression-bodied member property
public int MaxHealth => x ? y:z;

And...

// field with field initializer
public int MaxHealth = x ? y:z;

Is the same as the difference between...

public int MaxHealth
{
    get
    {
        return x ? y:z;
    }
}

And...

public int MaxHealth = x ? y:z;

Which - if you understand properties - should be obvious.

Just to be clear, though: the first listing is a property with a getter under the hood that will be called each time you access it. The second listing is is a field with a field initializer, whose expression is only evaluated once, when the type is instantiated.

This difference in syntax is actually quite subtle and can lead to a "gotcha" which is described by Bill Wagner in a post entitled "A C# 6 gotcha: Initialization vs. Expression Bodied Members".

While expression-bodied members are lambda expression-like, they are not lambda expressions. The fundamental difference is that a lambda expression results in either a delegate instance or an expression tree. Expression-bodied members are just a directive to the compiler to generate a property behind the scenes. The similarity (more or less) starts and end with the arrow (=>).

I'll also add that expression-bodied members are not limited to property members. They work on all these members:

• Properties
• Indexers
• Methods
• Operators

Added in C# 7.0

• Constructors
• Finalizers

However, they do not work on these members:

• Nested Types
• Events
• Fields

The error happens because of you are trying to map a numeric vector to data in geom_errorbar: GVW[1:64,3]. ggplot only works with data.frame.

In general, you shouldn't subset inside ggplot calls. You are doing so because your standard errors are stored in four separate objects. Add them to your original data.frame and you will be able to plot everything in one call.

Here with a dplyr solution to summarise the data and compute the standard error beforehand.

library(dplyr)
d <- GVW %>% group_by(Genotype,variable) %>%
    summarise(mean = mean(value),se = sd(value) / sqrt(n()))

ggplot(d, aes(x = variable, y = mean, fill = Genotype)) + 
  geom_bar(position = position_dodge(), stat = "identity", 
      colour="black", size=.3) +
  geom_errorbar(aes(ymin = mean - se, ymax = mean + se), 
      size=.3, width=.2, position=position_dodge(.9)) +
  xlab("Time") +
  ylab("Weight [g]") +
  scale_fill_hue(name = "Genotype", breaks = c("KO", "WT"), 
      labels = c("Knock-out", "Wild type")) +
  ggtitle("Effect of genotype on weight-gain") +
  scale_y_continuous(breaks = 0:20*4) +
  theme_bw()

It's kind of pointless to talk about "database performance", "query performance" is a better term here. And the answer is: it depends on the query, data that it operates on, indexes, hardware, etc. You can get an idea of how many rows are going to be scanned and what indexes are going to be used with EXPLAIN syntax.

2GB does not really count as a "large" database - it's more of a medium size.

Using std::bitset

int value = 123;
std::bitset<sizeof(int)> bits(value);
std::cout <<bits.to_string();

It’s because you tried to update a table without a WHERE that uses a KEY column.

The quick fix is to add SET SQL_SAFE_UPDATES=0; before your query :

SET SQL_SAFE_UPDATES=0; 

Or

close the safe update mode. Edit -> Preferences -> SQL Editor -> SQL Editor remove Forbid UPDATE and DELETE statements without a WHERE clause (safe updates) .

BTW you can use TRUNCATE TABLE tablename; to delete all the records .

You can use reduce instead of loops to appear clever, but at the risk of having your fellow developers think of you as a smart-ass.

function isArrayContentSame(a, b) {
  if (Array.isArray(a) && Array.isArray(b) && a.length == b.length) {
    a = a.concat().sort()
    b = b.concat().sort()
    return a.reduce((acc,e,i) => acc && e === b[i], true)
  } else {
    return false;
  }
}

Here's the map solution:

#include <iostream>
#include <map>

typedef std::map<char, char> BasePairMap;

int main()
{
    BasePairMap m;
    m['A'] = 'T';
    m['T'] = 'A';
    m['C'] = 'G';
    m['G'] = 'C';

    std::cout << "A:" << m['A'] << std::endl;
    std::cout << "T:" << m['T'] << std::endl;
    std::cout << "C:" << m['C'] << std::endl;
    std::cout << "G:" << m['G'] << std::endl;

    return 0;
}

maybe I'd go by this.

 SQL = SELECT REPLACE(myColumn, '""', '\'') FROM myTable

I used singlequotes because that's the one that registers string expressions in MySQL, or so I believe.

Hope that helps.

This post describes it very nicely.

In short: utf8_unicode_ci uses the Unicode Collation Algorithm as defined in the Unicode standards, whereas utf8_general_ci is a more simple sort order which results in "less accurate" sorting results.

I think @Dmitri has nice solution at Matching strings with wildcard https://stackoverflow.com/a/30300521/1726296

Based on his solution, I have created two extension methods. (credit goes to him)

May be helpful.

public static String WildCardToRegular(this String value)
{
        return "^" + Regex.Escape(value).Replace("\\?", ".").Replace("\\*", ".*") + "$";
}

public static bool WildCardMatch(this String value,string pattern,bool ignoreCase = true)
{
        if (ignoreCase)
            return Regex.IsMatch(value, WildCardToRegular(pattern), RegexOptions.IgnoreCase);

        return Regex.IsMatch(value, WildCardToRegular(pattern));
}

Usage:

string pattern = "file.*";

var isMatched = "file.doc".WildCardMatch(pattern)

or

string xlsxFile = "file.xlsx"
var isMatched = xlsxFile.WildCardMatch(pattern)

I want to collaborate a little with the solution for the server side. So, the server is saying it does not support DSA, this is because the openssh client does not activate it by default:

OpenSSH 7.0 and greater similarly disable the ssh-dss (DSA) public key algorithm. It too is weak and we recommend against its use.

So, to fix this this in the server side I should activate other Key algorithms like RSA o ECDSA. I just had this problem with a server in a lan. I suggest the following:

Update the openssh:

yum update openssh-server

Merge new configurations in the sshd_config if there is a sshd_config.rpmnew.

Verify there are hosts keys at /etc/ssh/. If not generate new ones, see man ssh-keygen.

$ ll /etc/ssh/
total 580
-rw-r--r--. 1 root root     553185 Mar  3  2017 moduli

-rw-r--r--. 1 root root        382 Aug 30 15:33 ssh_host_rsa_key.pub

Verify in the /etc/ssh/sshd_config the HostKey configuration. It should allow the configuration of RSA and ECDSA. (If all of them are commented by default it will allow too the RSA, see in man sshd_config the part of HostKey).

# HostKey for protocol version 1
#HostKey /etc/ssh/ssh_host_key
# HostKeys for protocol version 2
HostKey /etc/ssh/ssh_host_rsa_key
#HostKey /etc/ssh/ssh_host_dsa_key
HostKey /etc/ssh/ssh_host_ecdsa_key
HostKey /etc/ssh/ssh_host_ed25519_key

For the client side, create a key for ssh (not a DSA like in the question) by just doing this:

ssh-keygen

After this, because there are more options than ssh-dss(DSA) the client openssh (>=v7) should connect with RSA or better algorithm.

Here another good article.

This is my first question answered, I welcome suggestions :D .

$("#search").on("keyup", function() {
        var value = $(this).val().toLowerCase();
        $("tbody tr").filter(function() {
            $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
        });
    });

Assumption there is a one table with a tbody. you can also search with find or if the table has an ID you can use the id

Split a string delimited by characters and return all non-empty elements.

var names = ",Brian,Joe,Chris,,,";
var charSeparator = ",";
var result = names.Split(charSeparator, StringSplitOptions.RemoveEmptyEntries);

Prolog predicates 'unify' -

So, in an imperative langauge I'd write

function bazoo(integer foo)
{
   if(foo == 5)
       doSomething();
   else
       doSomeOtherThing();
}

In Prolog I'd write

bazoo(5) :-  doSomething.
bazoo(Foo) :- Foo =/= 5, doSomeOtherThing.

which, when you understand both styles, is actually a lot clearer.
"I'm bazoo for the special case when foo is 5"
"I'm bazoo for the normal case when foo isn't 5"

For a <input type='text'> element:

input { font-size: 18px; }

or for a <textarea>:

textarea { font-size: 18px; }

or for a <select>:

select { font-size: 18px; }

you get the drift.

This happened to me with a page loaded in via an iframe. The iframe src page had a 404 script reference. Obviously I couldn't find the script reference in the parent page, so it took me a while to find the culprit.

try this for sql server

CREATE TRIGGER yourNewTrigger ON yourSourcetable
FOR INSERT
AS

INSERT INTO yourDestinationTable
        (col1, col2    , col3, user_id, user_name)
    SELECT
        'a'  , default , null, user_id, user_name
        FROM inserted

go

public static boolean isNumeric(String str)
{
    return str.matches("-?\\d+(.\\d+)?");
}

CraigTP's regular expression (shown above) produces some false positives. E.g. "23y4" will be counted as a number because '.' matches any character not the decimal point.

Also it will reject any number with a leading '+'

An alternative which avoids these two minor problems is

public static boolean isNumeric(String str)
{
    return str.matches("[+-]?\\d*(\\.\\d+)?");
}

Google has released ADT v23.0.2. This solved many problems of previous ADT version 23.

Step-by-step:

• Menu Help ? Install New Software...
• For "Work with", select the Android source https://dl-ssl.google.com/android/eclipse
• Tick ADT v23.0 for installation, then click "Next"
• Eclipse will show "Install Remediation Page" since there is conflict with previous version. (If it does not, see below.) Select "Update my installation to be compatible with items being installed" to uninstall the old version and install the new one. After that, proceed with the usual steps.

Note: When I installed the new version of ADT, I didn't include the new version of "Android Native Development Tools" package. Instead, I installed the rest of packages first, and then installed "Android Native Development Tools". For a reason, if I try to install all the new packages including "Android Native Development Tools", the installation fails.

If there is no "Remediation page", the only way to remove the ADT plugin from Eclipse is to go to menu Help ? About Eclipse ? Installation Details and uninstall from there. But there is a risk of uninstalling Eclipse itself.

50 - List1[0][0] + List[0][1] - List[0][2]

List[0] gives you the first list in the list (try out print List[0]). Then, you index into it again to get the items of that list. Think of it this way: (List1[0])[0].

Recordsets have two important properties when looping through data, EOF (End-Of-File) and BOF (Beginning-Of-File). Recordsets are like tables and when you loop through one, you are literally moving from record to record in sequence. As you move through the records the EOF property is set to false but after you try and go past the last record, the EOF property becomes true. This works the same in reverse for the BOF property.

These properties let us know when we have reached the limits of a recordset.

Try this

    $(function() {

$('#clickMe').click(function(event) {
    var mytext = $('#myText').val();


    $('<div id="dialog">'+mytext+'</div>').appendTo('body');        
    event.preventDefault();

        $("#dialog").dialog({                   
            width: 600,
            modal: true,
            close: function(event, ui) {
                $("#dialog").remove();
                }
            });
    }); //close click
});

And in HTML

<h3 id="clickMe">Open dialog</h3>
<textarea cols="0" rows="0" id="myText" style="display:none">Some hidden text display none</textarea>

If you have the column it's very easy.

Using the designer, you could set the column as an identity (1,1): right click on the table ? design ? in part left (right click) ? properties ? in identity columns, select #column.

Properties:

Identity column:

As mentioned, only arrays are allowed. But to make it simple for you, you could dynamically convert the object into an array via a piping function as seen here https://gist.github.com/brev/3949705

Just declare the filter, and add it to ng-repeat :)

<div ng-app="myApp">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
<div ng-controller="Main">
  <div ng-repeat="release in releases | object2Array | orderBy:'environment_id'">{{release.environment_id}}</div>
</div>

<script>

var app = angular.module('myApp', []).filter('object2Array', function() {
    return function(input) {
      var out = []; 
      for(i in input){
        out.push(input[i]);
      }
      return out;
    }
  })
.controller('Main',function ($scope) {
        $scope.releases = {"tvl-c-wbap001 + tvl-webapp":{"timestamp":" 05:05:53 PM ","environment_id":"CERT5","release_header":"Projects/Dev","date":"19 Oct","release":"12.11.91-1"},"tvl-c-wbap401 + tvl-webapp":{"timestamp":" 10:07:25 AM ","environment_id":"CERT4","release_header":"Future Release","date":"15 Oct","release":"485-1"},"tvl-c-wbap301 + tvl-webapp":{"timestamp":" 07:59:48 AM ","environment_id":"CERT3","release_header":"Next Release","date":"15 Oct","release":"485-1"},"tvl-c-wbap201 + tvl-webapp":{"timestamp":" 03:34:07 AM ","environment_id":"CERT2","release_header":"Next Changes","date":"15 Oct","release":"13.12.3-1"},"tvl-c-wbap101 + tvl-webapp":{"timestamp":" 12:44:23 AM ","environment_id":"CERT1","release_header":"Production Mirror","date":"15 Oct","release":"13.11.309-1"},"tvl-s-wbap002 + tvl-webapp":{"timestamp":" 12:43:23 AM ","environment_id":"Stage2","date":"15 Oct","release":"13.11.310-1"},"tvl-s-wbap001 + tvl-webapp":{"timestamp":" 11:07:38 AM ","environment_id":"Stage1","release_header":"Production Mirror","date":"11 Oct","release":"13.11.310-1"},"tvl-p-wbap001 + tvl-webapp":{"timestamp":" 11:39:25 PM ","environment_id":"Production","release_header":"Pilots","date":"14 Oct","release":"13.11.310-1"},"tvl-p-wbap100 + tvl-webapp":{"timestamp":" 03:27:53 AM ","environment_id":"Production","release_header":"Non Pilots","date":"11 Oct","release":"13.11.309-1"}}

Just to rephrase, the key (Optional. A Function to execute to decide the order. Default is None) in sorted functions expects a function and you use lambda.

To define lambda, you specify the object property you want to sort and python's built-in sorted function will automatically take care of it.

If you want to sort by multiple properties then assign key = lambda x: (property1, property2).

To specify order-by, pass reverse= true as the third argument(Optional. A Boolean. False will sort ascending, True will sort descending. Default is False) of sorted function.

Add /y to the command line of xcopy:

Example:

xcopy /y c:\mmyinbox\test.doc C:\myoutbox

Back in the old days of Python, to call a function with arbitrary arguments, you would use apply:

apply(f,args,kwargs)

apply still exists in Python2.7 though not in Python3, and is generally not used anymore. Nowadays,

f(*args,**kwargs)

is preferred. The multiprocessing.Pool modules tries to provide a similar interface.

Pool.apply is like Python apply, except that the function call is performed in a separate process. Pool.apply blocks until the function is completed.

Pool.apply_async is also like Python's built-in apply, except that the call returns immediately instead of waiting for the result. An AsyncResult object is returned. You call its get() method to retrieve the result of the function call. The get() method blocks until the function is completed. Thus, pool.apply(func, args, kwargs) is equivalent to pool.apply_async(func, args, kwargs).get().

In contrast to Pool.apply, the Pool.apply_async method also has a callback which, if supplied, is called when the function is complete. This can be used instead of calling get().

For example:

import multiprocessing as mp
import time

def foo_pool(x):
    time.sleep(2)
    return x*x

result_list = []
def log_result(result):
    # This is called whenever foo_pool(i) returns a result.
    # result_list is modified only by the main process, not the pool workers.
    result_list.append(result)

def apply_async_with_callback():
    pool = mp.Pool()
    for i in range(10):
        pool.apply_async(foo_pool, args = (i, ), callback = log_result)
    pool.close()
    pool.join()
    print(result_list)

if __name__ == '__main__':
    apply_async_with_callback()

may yield a result such as

[1, 0, 4, 9, 25, 16, 49, 36, 81, 64]

Notice, unlike pool.map, the order of the results may not correspond to the order in which the pool.apply_async calls were made.

So, if you need to run a function in a separate process, but want the current process to block until that function returns, use Pool.apply. Like Pool.apply, Pool.map blocks until the complete result is returned.

If you want the Pool of worker processes to perform many function calls asynchronously, use Pool.apply_async. The order of the results is not guaranteed to be the same as the order of the calls to Pool.apply_async.

Notice also that you could call a number of different functions with Pool.apply_async (not all calls need to use the same function).

In contrast, Pool.map applies the same function to many arguments. However, unlike Pool.apply_async, the results are returned in an order corresponding to the order of the arguments.

Update to Swift 3

let image = UIImage(named: "name")
let button = UIButton(type: .custom)
button.frame = CGRect(x: 100, y: 100, width: 100, height: 100)
button.setImage(image, for: .normal)
button.addTarget(self, action: #selector(self.btnAbsRetClicked(_:)), for:.touchUpInside)

Adding the following two lines before importing pylab seems to work for me

import matplotlib
matplotlib.use("gtk")

import sys
import pylab
import numpy as np

#!/bin/bash

if getopts "n:" arg; then
  echo "Welcome $OPTARG"
fi

Save it as sample.sh and try running

sh sample.sh -n John

in your terminal.

In most project types, your async "up" and "down" will end at an async void event handler or returning a Task to your framework.

However, Console apps do not support this.

You can either just do a Wait on the returned task:

static void Main()
{
  MainAsync().Wait();
  // or, if you want to avoid exceptions being wrapped into AggregateException:
  //  MainAsync().GetAwaiter().GetResult();
}

static async Task MainAsync()
{
  ...
}

or you can use your own context like the one I wrote:

static void Main()
{
  AsyncContext.Run(() => MainAsync());
}

static async Task MainAsync()
{
  ...
}

More information for async Console apps is on my blog.

This article is a good primer on fetching data with hooks: https://www.robinwieruch.de/react-hooks-fetch-data/

Essentially, include the fetch function definition inside useEffect:

useEffect(() => {
  const fetchBusinesses = () => {
    return fetch("theUrl"...
      // ...your fetch implementation
    );
  }

  fetchBusinesses();
}, []);

If you want to setup for temporary purpose, just execute below command.

1. open command prompt < run --> cmd >
2. Run below command.
   set PATH=C:\Program Files\Git\bin;%PATH%
3. Type git, it will work.

This is valid for current window/cell only, if you will close command prompt, everything will get vanish. For permanently setting, set GIT in environment variable.

a. press Window+Pause
b. click on Advance system setting.

c. Click on Environment variable under Advance Tab.

d. Edit Path Variable.

e. Add below line in end of statement.
;c:\Program Files\Git\bin;

f. Press OK!!
g. Open new command prompt .
h. Type git and press Enter

I would use FMOD to do this for your game. It has the ability to play any file mostly for sounds and is pretty simple to implement in C++. using FMOD and Dir3ect X together can be powerful and not that difficult. If you are familiar with Singleton classes I would create a Singleton class of a sound manager in your win main cpp and then have access to it whenever to load or play new music or sound effects. here's an audio manager example

    #pragma once

    FMOD::System* GetSystem(void)
        {return soundSystem;}

    // Sound playing
    void Play(FMOD::Sound* sound);  // Play a sound/music with default channel
    void PlaySFX(FMOD::Sound* sound);   // Play a sound effect with custom channel
    void PlayBGM(FMOD::Sound* sound);   // Play background music with custom channel

    // Volume adjustment methods

    void SetSFXVolume(float volume);

    static AudioManager* instance;  // Singleton instance
    AudioManager(void);  // Constructor

    FMOD::System* soundSystem;  // Sound system object
    FMOD_RESULT result;
    FMOD::Channel* bgmChannel;  // Channel for background music

    An example of reading a file:
Dim sFileText as String
Dim iFileNo as Integer
iFileNo = FreeFile
'open the file for reading
Open "C:\Test.txt" For Input As #iFileNo
'change this filename to an existing file! (or run the example below first)

'read the file until we reach the end
Do While Not EOF(iFileNo)
Input #iFileNo, sFileText
'show the text (you will probably want to replace this line as appropriate to your program!)
MsgBox sFileText
Loop

'close the file (if you dont do this, you wont be able to open it again!)
Close #iFileNo
(note: an alternative to Input # is Line Input # , which reads whole lines).


An example of writing a file:
Dim sFileText as String
Dim iFileNo as Integer
iFileNo = FreeFile
'open the file for writing
Open "C:\Test.txt" For Output As #iFileNo
'please note, if this file already exists it will be overwritten!

'write some example text to the file
Print #iFileNo, "first line of text"
Print #iFileNo, " second line of text"
Print #iFileNo, "" 'blank line
Print #iFileNo, "some more text!"

'close the file (if you dont do this, you wont be able to open it again!)
Close #iFileNo

After a wild goose chase with tons of Google searches and burteforce attempts, I think I found how to solve this problem.

Steps undertaken to solve the problem:

1. Uninstall R
2. Reinstall R

3. Install ggplot with the dependencies argument to install.packages set to TRUE

   install.packages("ggplot2",dependencies = TRUE)

4. The above step still does NOT include the Rcpp dependency so that has to be manually installed using the following command

   install.packages("Rcpp")

However, while the above command successfully downloads Rcpp, for some reason, it fails to explode the ZIP file and install it in my R's library folder citing the following error:

package ‘Rcpp’ successfully unpacked and MD5 sums checked Warning in install.packages : unable to move temporary installation ‘C:\Root_Prgs\Data_Science_SW\R\R-3.2.3\library\file27b8ef47b6d\Rcpp’ to ‘C:\Root_Prgs\Data_Science_SW\R\R-3.2.3\library\Rcpp’

The downloaded binary packages are in C:\Users\MY_USER_ID\AppData\Local\Temp\Rtmp25XQ0S\downloaded_packages

5. Note that the above output says "Warning" but actually, it is an indication of failure to install the Rcpp package successfully within the repository. I then used the Tools-->Install packages--> From ZIP file and pointed to the location of the "downloaded binary packages" in the message above -

C:\Users\MY_USER_ID\AppData\Local\Temp\Rtmp25XQ0S\downloaded_packages\Rcpp_0.12.3.zip

6. This led to successful installation of Rcpp in my R\R-3.2.3\library folder, thereby ensuring that Rcpp is now available when I attempt to load the library for ggplot2. I could not do this step in the past because my previous installation of R would throw error stating that Rcpp cannot be imported. However, the same command worked after I uninstalled and reinstalled R, which is ODD.

   install.packages("C:/Users/MY_USER_ID/AppData/Local/Temp/Rtmp25XQ0S/downloaded_packages/Rcpp_0.12.3.zip", repos = NULL, type = "win.binary") package ‘Rcpp’ successfully unpacked and MD5 sums checked`

7. I was finally able to load the ggplot2 library successfully.

   library(ggplot2)

From verify documentation:

If a certificate is found which is its own issuer it is assumed to be the root CA.

In other words, root CA needs to self signed for verify to work. This is why your second command didn't work. Try this instead:

openssl verify -CAfile RootCert.pem -untrusted Intermediate.pem UserCert.pem

It will verify your entire chain in a single command.

Uninstalling pycparser:

pip uninstall pycparser

Reinstall pycparser:

I got same error while installing termcolor and I fixed it by reinstalling it .

The basic difference is that undefined and null represent different concepts.

If only null was available, you would not be able to determine whether null was set intentionally as the value or whether the value has not been set yet unless you used cumbersome error catching: eg

var a;

a == null; // This is true
a == undefined; // This is true;
a === undefined; // This is true;

However, if you intentionally set the value to null, strict equality with undefined fails, thereby allowing you to differentiate between null and undefined values:

var b = null;
b == null; // This is true
b == undefined; // This is true;
b === undefined; // This is false;

Check out the reference here instead of relying on people dismissively saying junk like "In summary, undefined is a JavaScript-specific mess, which confuses everyone". Just because you are confused, it does not mean that it is a mess.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/undefined

This behaviour is also not specific to JavaScript and it completes the generalised concept that a boolean result can be true, false, unknown (null), no value (undefined), or something went wrong (error).

http://en.wikipedia.org/wiki/Undefined_value

The ab (apache bench) tool allows you to send many requests to a single page and you specify how many clients you want to be used and how many concurrent connection you want.

This may be the first step when developing a site. Just test some pages with a specific load. This way of benchmarking may have some problem, like caching being over used.

Later you may want a tool that simulate some concrete traffic and not for a single page. I don't have a refence handy on such tool yet.

I found several posts telling me to run several gpg commands, but they didn't solve the problem because of two things. First, I was missing the debian-keyring package on my system and second I was using an invalid keyserver. Try different keyservers if you're getting timeouts!

Thus, the way I fixed it was:

apt-get install debian-keyring
gpg --keyserver pgp.mit.edu --recv-keys 1F41B907
gpg --armor --export 1F41B907 | apt-key add -

Then running a new "apt-get update" worked flawlessly!

In my case I had to set MaxHeight and replace IsEnabled="False" by IsReadOnly="True"

I will give you steps to writing and compiling code. Use this example:

 public class Paycheck {
    public static void main(String args[]) {
        double amountInAccount;
        amountInAccount = 128.57;
        System.out.print("You earned $");
        System.out.print(amountInAccount);
        System.out.println(" at work today.");
    }
}

1. Save the code as Paycheck.java
2. Go to terminal and type cd Desktop
3. Type javac Paycheck.java
4. Type java Paycheck
5. Enjoy your program!

POD_HOST=$(kubectl get pod $POD_NAME --template={{.status.podIP}})

There is a public domain TimeZone library for .NET. Really useful. It will answer your needs.

Solving the general-case timezone problem is harder than you think.

Take a look at this answer: ImportError: no module named win32api

use is a method to configure the middleware used by the routes of the Express HTTP server object. The method is defined as part of Connect that Express is based upon.

Update Starting with version 4.x, Express no longer depends on Connect.

The middleware functions that were previously included with Express are now in separate modules; see the list of middleware functions.

Add image for selected UIButton

button.addTarget(self, action: #selector(self.onclickDateCheckMark), for: .touchUpInside)//Target 
button.setImage(UIImage.init(named: "uncheck"), for: UIControl.State.normal)//When selected
button.setImage(UIImage.init(named: "check"), for: UIControl.State.highlighted)//When highlighted
button.setImage(UIImage.init(named: "check"), for: UIControl.State.selected)//When selected

But if you want to change selected button image you need to change it's selected state. Then only selected image will appear in your button.

@objc func onclickDateCheckMark(sender:UIButton) {
    if sender.isSelected == true {
        sender.isSelected = false
        print("not Selected")
    }else {
        sender.isSelected = true
        print("Selected")

    }
}

If you know list comprehensions:

lines = [line[5:] for line in file.readlines() if line[:5] == "Path="]

If you want to save it as .fig file, hgsave is the function in Matlab R2012a. In later versions, savefig may also work.

TL;DR answer - There is no real solution besides "delete app and reinstall".

This answer is not satisfactory for many situations, when you have an existing database that needs to not get deleted within the app.

Lukasz and plivesey are the only ones with solutions that don't require delete, but neither worked for me.

Most of the answers above require you to specify precision. But what if you want to display floats like this, with no unnecessary zeros:

1
0.1
0.01
0.001
0.0001
0.00001
0.000001
0.000000000001

attributes[.foregroundColor] = UIColor.red

let attributedString = NSAttributedString(string: "Very Bad", attributes: attributes)

label.attributedText = attributedString

For Swift 4:

var attributes = [NSAttributedStringKey: AnyObject]()
attributes[.foregroundColor] = UIColor.red

let attributedString = NSAttributedString(string: "Very Bad", attributes: attributes)

label.attributedText = attributedString

For Swift 3:

var attributes = [String: AnyObject]()
attributes[NSForegroundColorAttributeName] = UIColor.red

let attributedString = NSAttributedString(string: "Very Bad", attributes: attributes)

label.attributedText = attributedString

I've come across this "deep object copy" function that I've found handy for duplicating objects by value. It doesn't use jQuery, but it certainly is deep.

http://www.overset.com/2007/07/11/javascript-recursive-object-copy-deep-object-copy-pass-by-value/

An nvarchar column can store any Unicode data. A varchar column is restricted to an 8-bit codepage. Some people think that varchar should be used because it takes up less space. I believe this is not the correct answer. Codepage incompatabilities are a pain, and Unicode is the cure for codepage problems. With cheap disk and memory nowadays, there is really no reason to waste time mucking around with code pages anymore.

All modern operating systems and development platforms use Unicode internally. By using nvarchar rather than varchar, you can avoid doing encoding conversions every time you read from or write to the database. Conversions take time, and are prone to errors. And recovery from conversion errors is a non-trivial problem.

If you are interfacing with an application that uses only ASCII, I would still recommend using Unicode in the database. The OS and database collation algorithms will work better with Unicode. Unicode avoids conversion problems when interfacing with other systems. And you will be preparing for the future. And you can always validate that your data is restricted to 7-bit ASCII for whatever legacy system you're having to maintain, even while enjoying some of the benefits of full Unicode storage.

For your question answer is android.R.id.text1 is int: The id of the TextView within the layout resource to be populated.

ArrayAdapter has so many constructors with different number of arguments I'm mention some of them

ArrayAdapter(Context context, int resource)
ArrayAdapter(Context context, int resource, int textViewResourceId)
ArrayAdapter(Context context, int resource, T[] objects)
ArrayAdapter(Context context, int resource, int textViewResourceId, T[] objects)
ArrayAdapter(Context context, int resource, List<T> objects)
ArrayAdapter(Context context, int resource, int textViewResourceId, List<T> objects)

Now you can understand each and every constructor is different and they used different list of arguments.

And simple answer is you can use ArrayAdapter with text view inside a target xml file or without. It is doesn't matter. And you not need specify text view id you can use it without. But you may need to go with some advance option with your simple list view you must go with a text view.!

Here sample example

ArrayAdapter adapter = new ArrayAdapter<String>(this,R.layout.ListView,StringArray);
ListView listView = (ListView) findViewById(R.id.listview);
listView.setAdapter(adapter);

This is also a valid code you can use with much more clear.

It turns out you can do this, with the help of the built-in Zip File System provider. However, passing a resource URI directly to Paths.get won't work; instead, one must first create a zip filesystem for the jar URI without the entry name, then refer to the entry in that filesystem:

static Path resourceToPath(URL resource)
throws IOException,
       URISyntaxException {

    Objects.requireNonNull(resource, "Resource URL cannot be null");
    URI uri = resource.toURI();

    String scheme = uri.getScheme();
    if (scheme.equals("file")) {
        return Paths.get(uri);
    }

    if (!scheme.equals("jar")) {
        throw new IllegalArgumentException("Cannot convert to Path: " + uri);
    }

    String s = uri.toString();
    int separator = s.indexOf("!/");
    String entryName = s.substring(separator + 2);
    URI fileURI = URI.create(s.substring(0, separator));

    FileSystem fs = FileSystems.newFileSystem(fileURI,
        Collections.<String, Object>emptyMap());
    return fs.getPath(entryName);
}

Update:

It’s been rightly pointed out that the above code contains a resource leak, since the code opens a new FileSystem object but never closes it. The best approach is to pass a Consumer-like worker object, much like how Holger’s answer does it. Open the ZipFS FileSystem just long enough for the worker to do whatever it needs to do with the Path (as long as the worker doesn’t try to store the Path object for later use), then close the FileSystem.

You can also make use of FilesystemIterator. It requires even less code then DirectoryIterator, and automatically removes . and ...

// Let's traverse the images directory
$fileSystemIterator = new FilesystemIterator('images');

$entries = array();
foreach ($fileSystemIterator as $fileInfo){
    $entries[] = $fileInfo->getFilename();
}

var_dump($entries);

//OUTPUT
object(FilesystemIterator)[1]

  1 => string 'Chrysanthemum.jpg' (length=17)
  2 => string 'Desert.jpg' (length=10)

The First<TSource>(IEnumerable<TSource>) method throws an exception if source contains no elements. To instead return a default value when the source sequence is empty, use the FirstOrDefault method.

Here is a complete solution to add a UIButton programmatically with the targetAction.
Swift 2.2

override func viewDidLoad() {
  super.viewDidLoad()

  let button = UIButton(frame: CGRect(x: 100, y: 100, width: 100, height: 50))
  button.backgroundColor = .greenColor()
  button.setTitle("Test Button", forState: .Normal)
  button.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside)

  self.view.addSubview(button)
}

func buttonAction(sender: UIButton!) {
  print("Button tapped")
}

It is probably better to use NSLayoutConstraint rather than frame to correctly place the button for each iPhone screen.

Updated code to Swift 3.1:

override func viewDidLoad() {
  super.viewDidLoad()

  let button = UIButton(frame: CGRect(x: 100, y: 100, width: 100, height: 50))
  button.backgroundColor = .green
  button.setTitle("Test Button", for: .normal)
  button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)

  self.view.addSubview(button)
}

func buttonAction(sender: UIButton!) {
  print("Button tapped")
}

Updated code to Swift 4.2:

override func viewDidLoad() {
  super.viewDidLoad()

  let button = UIButton(frame: CGRect(x: 100, y: 100, width: 100, height: 50))
  button.backgroundColor = .green
  button.setTitle("Test Button", for: .normal)
  button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)

  self.view.addSubview(button)
}

@objc func buttonAction(sender: UIButton!) {
  print("Button tapped")
}

The above still works if func buttonAction is declared private or internal.

In my case I'm using an external maven installation with m2e. I've added my proxy settings to the external maven installation's settings.xml file. These settings haven't been used by m2e even after I've set the external maven installation as default maven installation.

To solve the problem I've configured the global maven settings file within eclipse to be the settings.xml file from my external maven installation.

Now eclipse can download the required artifacts.

In Python everything has a type. A Python function will do anything it is asked to do if the type of arguments support it.

Example: foo will add everything that can be __add__ed ;) without worrying much about its type. So that means, to avoid failure, you should provide only those things that support addition.

def foo(a,b):
    return a + b

class Bar(object):
    pass

class Zoo(object):
    def __add__(self, other):
        return 'zoom'

if __name__=='__main__':
    print foo(1, 2)
    print foo('james', 'bond')
    print foo(Zoo(), Zoo())
    print foo(Bar(), Bar()) # Should fail

import matplotlib.pyplot as plt

fig, ax = plt.subplots(2, 2)

To turn off axes for all subplots, do either:

[axi.set_axis_off() for axi in ax.ravel()]

or

map(lambda axi: axi.set_axis_off(), ax.ravel())

Just add public properties to the user control.

You can add [Category("MyCategory")] and [Description("A property that controls the wossname")] attributes to make it nicer, but as long as it's a public property it should show up in the property panel.

You could use std::search with a custom predicate.

#include <locale>
#include <iostream>
#include <algorithm>
using namespace std;

// templated version of my_equal so it could work with both char and wchar_t
template<typename charT>
struct my_equal {
    my_equal( const std::locale& loc ) : loc_(loc) {}
    bool operator()(charT ch1, charT ch2) {
        return std::toupper(ch1, loc_) == std::toupper(ch2, loc_);
    }
private:
    const std::locale& loc_;
};

// find substring (case insensitive)
template<typename T>
int ci_find_substr( const T& str1, const T& str2, const std::locale& loc = std::locale() )
{
    typename T::const_iterator it = std::search( str1.begin(), str1.end(), 
        str2.begin(), str2.end(), my_equal<typename T::value_type>(loc) );
    if ( it != str1.end() ) return it - str1.begin();
    else return -1; // not found
}

int main(int arc, char *argv[]) 
{
    // string test
    std::string str1 = "FIRST HELLO";
    std::string str2 = "hello";
    int f1 = ci_find_substr( str1, str2 );

    // wstring test
    std::wstring wstr1 = L"????? ??????";
    std::wstring wstr2 = L"??????";
    int f2 = ci_find_substr( wstr1, wstr2 );

    return 0;
}

This tool is working very well right now.

I might be misunderstanding your question, so apologies if I am.

If you're looking for the words "Quid", "Application Number", etc. to be bold, just wrap them in <strong> tags:

<strong>Quid</strong>: ...

Hope that helps!

The code for word-wrapping (breaking at spaces) provided by @Gaby Petrioli is very helpful. I've extended his code to provide support for newline characters \n. Also, often times it's useful to have the dimensions of the bounding box, so multiMeasureText() returns both the width and the height.

You can see the code here: http://jsfiddle.net/jeffchan/WHgaY/76/

It is not possible. §2.3 says that "." is an unreserved character and that "URIs that differ in the replacement of an unreserved character with its corresponding percent-encoded US-ASCII octet are equivalent". Therefore, /%2E%2E/ is the same as /../, and that will get normalized away.

(This is a combination of an answer by bobince and a comment by slowpoison.)

Ahahaha, here's a funny way I just came up with to do this:

select SYSDATE - ROWNUM
from shipment_weights sw
where ROWNUM < 365;

where shipment_weights is any large table;

Peg the pattern to find "\\.dbf" at the end of the string using the $ character:

list.files(pattern = "\\.dbf$")

i don't know about converting into a byte array, but it's easy to convert it into a string:

import base64

with open("t.png", "rb") as imageFile:
    str = base64.b64encode(imageFile.read())
    print str

Since the question was first asked, there has been a change to that answer from a flat out "no" to a "kind of"

http://github.com/facebook/hiphop-php/wiki

Hip Hop for PHP was a compiler that took PHP code and turned it into highly optimized C++ Apparently, some functions are not supported (for example 'explode')

I found this question while looking for more information on how to implement HipHop and thought I'd speak up :)

Since 2013 Facebook no longer use it, however, and it has been discontinued in favour of HHVM, which is not a compiler: https://en.wikipedia.org/wiki/HipHop_for_PHP

To get the directory, you can use the code below:

File cacheDir = new File(Environment.getExternalStorageDirectory() + File.separator + "");

1) Run ipconfig command in cmd

2) You will get result like this

3) Then use IPv4 Address of VMWare Network Adapter 1 followed by port number

In My Case its 8080, so instead of using localhost:8080

I am using 192.168.56.1:8080

Done.....

may be you should try like this

int sdRate=5;
//text_Rate is a TextView
text_Rate.setText(sdRate+""); //gives error

if (data[j] =='B'){
    row.cells[j].title="Basic";
}

In Java script conditionally adding title by comparing value of Data. The Table is generated by Java script dynamically.

CREATE TABLE contact (contactid int, name varchar(100), dob datetime)
INSERT INTO contact SELECT 1, 'Joe', '1974-01-01'

DECLARE @columns varchar(8000)

SELECT @columns = ISNULL(@columns + ', ','') + QUOTENAME(column_name)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'contact' AND COLUMN_NAME <> 'dob'
ORDER BY ORDINAL_POSITION

EXEC ('SELECT ' + @columns + ' FROM contact')

Explanation of the code:

1. Declare a variable to store a comma separated list of column names. This defaults to NULL.
2. Use a system view to determine the names of the columns in our table.
3. Use SELECT @variable = @variable + ... FROM to concatenate the column names. This type of SELECT does not not return a result set. This is perhaps undocumented behaviour but works in every version of SQL Server. As an alternative you could use SET @variable = (SELECT ... FOR XML PATH('')) to concatenate strings.
4. Use the ISNULL function to prepend a comma only if this is not the first column name. Use the QUOTENAME function to support spaces and punctuation in column names.
5. Use the WHERE clause to hide columns we don't want to see.
6. Use EXEC (@variable), also known as dynamic SQL, to resolve the column names at runtime. This is needed because we don't know the column names at compile time.

I believe that you're looking for numpy.split or possibly numpy.array_split if the number of sections doesn't need to divide the size of the array properly.

Get-QADUser -SamAccountName LoginID | % {$_.MemberOf } | Get-QADGroup | select name

You're trying to open each file twice! First you do:

infile=open('110331_HS1A_1_rtTA.result','r')

and then you pass infile (which is a file object) to the open function again:

with open (infile, mode='r', buffering=-1)

open is of course expecting its first argument to be a file name, not an opened file!

Open the file once only and you should be fine.

I solved this with 2 dimensional array. Input: aaaabbbcdefggggh Output:a4b3cdefg4h

int[][] arr = new int[10][2];
    String st = "aaaabbbcdefggggh";
    char[] stArr = st.toCharArray();
    int i = 0;
    int j = 0;
    for (int k = 0; k < stArr.length; k++) {
        if (k == 0) {
            arr[i][j] = stArr[k];
            arr[i][j + 1] = 1;
        } else {
            if (arr[i][j] == stArr[k]) {
                arr[i][j + 1] = arr[i][j + 1] + 1;
            } else {
                arr[++i][j] = stArr[k];
                arr[i][j + 1] = 1;
            }
        }
    }
    System.out.print(arr.length);
    String output = "";
    for (int m = 0; m < arr.length; m++) {
        if (arr[m][1] > 0) {
            String character = Character.toString((char) arr[m][0]);
            String cnt = arr[m][1] > 1 ? String.valueOf(arr[m][1]) : "";
            output = output + character + cnt;

        }
    }
    System.out.print(output);

Use the code below,

TableRow _tableRow =(TableRow)findViewById(R.id.tableRowMainBody);
tableRow.requestFocus();

that should work.

Based on the solution by Jason Bunting, here is what I use now.

The whole thing is for the jQuery tablesorter plug-in: For (nearly correct) sorting of non-English tables with tablesorter plugin it is necessary to make use of a custom textExtraction function.

This one:

• translates the most common accented letters to unaccented ones (the list of supported letters is easily expandable)
• changes dates in German format ('dd.mm.yyyy') to a recognized format ('yyyy-mm-dd')

Be careful to save the JavaScript file in UTF-8 encoding or it won't work.

// file encoding must be UTF-8!
function getTextExtractor()
{
  return (function() {
    var patternLetters = /[öäüÖÄÜáàâéèêúùûóòôÁÀÂÉÈÊÚÙÛÓÒÔß]/g;
    var patternDateDmy = /^(?:\D+)?(\d{1,2})\.(\d{1,2})\.(\d{2,4})$/;
    var lookupLetters = {
      "ä": "a", "ö": "o", "ü": "u",
      "Ä": "A", "Ö": "O", "Ü": "U",
      "á": "a", "à": "a", "â": "a",
      "é": "e", "è": "e", "ê": "e",
      "ú": "u", "ù": "u", "û": "u",
      "ó": "o", "ò": "o", "ô": "o",
      "Á": "A", "À": "A", "Â": "A",
      "É": "E", "È": "E", "Ê": "E",
      "Ú": "U", "Ù": "U", "Û": "U",
      "Ó": "O", "Ò": "O", "Ô": "O",
      "ß": "s"
    };
    var letterTranslator = function(match) { 
      return lookupLetters[match] || match;
    }

    return function(node) {
      var text = $.trim($(node).text());
      var date = text.match(patternDateDmy);
      if (date)
        return [date[3], date[2], date[1]].join("-");
      else
        return text.replace(patternLetters, letterTranslator);
    }
  })();
}

You can use it like this:

$("table.sortable").tablesorter({ 
  textExtraction: getTextExtractor()
}); 

I'm posting this just to cover all possibilities since neither of the other solutions worked for me (they threw errors due angular-bootstrap template dependencies, among others).

While you are developing/debugging a specific template, you can ensure it always refreshes by included a timestamp in the path, like this:

       $modal.open({
          // TODO: Only while dev/debug. Remove later.
          templateUrl: 'core/admin/organizations/modal-selector/modal-selector.html?nd=' + Date.now(),
          controller : function ($scope, $modalInstance) {
            $scope.ok = function () {
              $modalInstance.close();
            };
          }
        });

Note the final ?nd=' + Date.now() in the templateUrl variable.

I usually handle things like this with an extension method. Here is one way implemented in a console app:

namespace ConsoleApplication10
{
    class Program
    {
        static void Main(string[] args)
        {
            CheckIfNumeric("A");
            CheckIfNumeric("22");
            CheckIfNumeric("Potato");
            CheckIfNumeric("Q");
            CheckIfNumeric("A&^*^");

            Console.ReadLine();
        }

        private static void CheckIfNumeric(string input)
        {
            if (input.IsNumeric())
            {
                Console.WriteLine(input + " is numeric.");
            }
            else
            {
                Console.WriteLine(input + " is NOT numeric.");
            }
        }
    }

    public static class StringExtensions
    {
        public static bool IsNumeric(this string input)
        {
            return Regex.IsMatch(input, @"^\d+$");
        }
    }
}

Output:

A is NOT numeric.

22 is numeric.

Potato is NOT numeric.

Q is NOT numeric.

A&^*^ is NOT numeric.

Note, here are a few other ways to check for numbers using RegEx.

There is no point in retrieving first element from a Set. If you have such kind of requirement use ArrayList instead of sets. Sets do not allow duplicates. They contain distinct elements.

The easiest way to put the loader in the website.

HTML:

<div id="loading"></div>

CSS:

#loading {
position: fixed;
width: 100%;
height: 100vh;
background: #fff url('images/loader.gif') no-repeat center center;
z-index: 9999;
}

JQUERY:

<script>
jQuery(document).ready(function() {
    jQuery('#loading').fadeOut(3000);
});
</script>

Generally, never.

However, sometimes you need to catch specific errors.

If you're writing framework-ish code (loading 3rd party classes), it might be wise to catch LinkageError (no class def found, unsatisfied link, incompatible class change).

I've also seen some stupid 3rd-party code throwing subclasses of Error, so you'll have to handle those as well.

By the way, I'm not sure it isn't possible to recover from OutOfMemoryError.

Don't follow other answers

Well, you can follow them :). But I don't think that doing a commit and then resetting the branch to remove that commit and similar workarounds suggested in other answers are the clean way to solve this issue.

Clean solution

The following solution seems to be much cleaner to me and it's also suggested by the Git itself — try to execute git status in the repository with a conflict:

Unmerged paths:
  (use "git reset HEAD <file>..." to unstage)
  (use "git add <file>..." to mark resolution)

So let's do what Git suggests (without doing any useless commits):

1. Manually (or using some merge tool, see below) resolve the conflict(s).
2. Use git reset to mark conflict(s) as resolved and unstage the changes. You can execute it without any parameters and Git will remove everything from the index. You don't have to execute git add before.
3. Finally, remove the stash with git stash drop, because Git doesn't do that on conflict.

Translated to the command-line:

$ git stash pop

# ...resolve conflict(s)

$ git reset

$ git stash drop

Explanation of the default behavior

There are two ways of marking conflicts as resolved: git add and git reset. While git reset marks the conflicts as resolved and removes files from the index, git add also marks the conflicts as resolved, but keeps files in the index.

Adding files to the index after a conflict is resolved is on purpose. This way you can differentiate the changes from the previous stash and changes you made after the conflict was resolved. If you don't like it, you can always use git reset to remove everything from the index.

Merge tools

I highly recommend using any of 3-way merge tools for resolving conflicts, e.g. KDiff3, Meld, etc., instead of doing it manually. It usually solves all or majority of conflicts automatically itself. It's huge time-saver!

Just create a new branch with git checkout -b ABC_1; your uncommitted changes will be kept, and you then commit them to that branch.

I'm not sure that there isn't a bit too much fussing around here. I recently had problems with md5 and files stored as blobs on MySQL so I experimented with various file sizes and the straightforward Python approach, viz:

FileHash=hashlib.md5(FileData).hexdigest()

I could detect no noticeable performance difference with a range of file sizes 2Kb to 20Mb and therefore no need to 'chunk' the hashing. Anyway, if Linux has to go to disk, it will probably do it at least as well as the average programmer's ability to keep it from doing so. As it happened, the problem was nothing to do with md5. If you're using MySQL, don't forget the md5() and sha1() functions already there.

Deprecated solution

valueLink/checkedLink are deprecated from core React, because it is confusing some users. This answer won't work if you use a recent version of React. But if you like it, you can easily emulate it by creating your own Input component

Old answer content:

What you want to achieve can be much more easily achieved using the 2-way data binding helpers of React.

var Hello = React.createClass({
    mixins: [React.addons.LinkedStateMixin],
    getInitialState: function() {
        return {input1: 0, input2: 0};
    },

    render: function() {
        var total = this.state.input1 + this.state.input2;
        return (
            <div>{total}<br/>
                <input type="text" valueLink={this.linkState('input1')} />;
                <input type="text" valueLink={this.linkState('input2')} />;
            </div>
        );
    }

});

React.renderComponent(<Hello />, document.getElementById('content'));

Easy right?

You can even implement your own mixin

That error message means that there was not response OR the server could not be connected.

The following settings worked on my end:

'stream' => [
        'ssl' => [
            'allow_self_signed' => true,
            'verify_peer' => false,
            'verify_peer_name' => false,
        ],
    ]

Note that my SMTP settings are:

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=465
MAIL_USERNAME=[full gmail address]
MAIL_PASSWORD=[App Password obtained after two step verification]
MAIL_ENCRYPTION=ssl

Using a list comprehension is the most Pythonic way:

>>> strings = ["first", "", "second"]
>>> [x for x in strings if x]
['first', 'second']

If the list must be modified in-place, because there are other references which must see the updated data, then use a slice assignment:

strings[:] = [x for x in strings if x]

For your need:

UPDATE classes 
SET `date` = DATE_ADD(`date`, INTERVAL 2 DAY)
WHERE id = 161

And it's unlikely too -- EOT is a fairly restrictive format that is supported only by IE. Both Safari 3.1 and Firefox 3.1 (well the current alpha) and possibly Opera 9.6 support true type font (ttf) embedding, and at least Safari supports SVG fonts through the same mechanism. A list apart had a good discussion about this a while back.

if ( $('#myfav').children().length > 0 ) {
     // do something
}

This should work. The children() function returns a JQuery object that contains the children. So you just need to check the size and see if it has at least one child.

my approach will be (your json example is not well formed.. guess thats only a sample)

jq '.Front[] | [.Name,.Out,.In,.Groups] | join("|")'  front.json  > output.txt

returns something like this

"new.domain.com-80|8.8.8.8|192.168.2.2:80|192.168.3.29:80 192.168.3.30:80"
"new.domain.com -443|8.8.8.8|192.168.2.2:443|192.168.3.29:443 192.168.3.30:443"

and grep the output with regular expression.

Sometimes you can retreive the phonenumber with a USSD request to your operator. For example I can get my phonenumber by dialing *116# This can probably be done within an app, I guess, if the USSD responce somehow could be catched. Offcourse this is not a method I would recommend to use within an app that is to be distributed, the code may even differ between operators.

Check if there is any zombie process using "top" command.

docker ps | grep <<container name>> 

Get the container id.

ps -ef | grep <<container id>>

ps -ef|grep defunct | grep java

And kill the container by Parent PID .

If you also want to preserve the original file name, try with:

wget --content-disposition --trust-server-names -i list_of_urls.txt

Delete all spaces and line breaks between <textarea> opening and closing </textarea> tags.

<textarea placeholder="YOUR TEXT"></textarea>  ///Correct one

<textarea placeholder="YOUR TEXT"> </textarea>  ///Bad one It's treats as a value so browser won't display the Placeholder value

<textarea placeholder="YOUR TEXT"> 
</textarea>  ///Bad one 

On my server, the nginx cache folder is at /data/nginx/cache/

So I removed it only: sudo rm -rf /data/nginx/cache/

Hope this will help anyone.

The very simplest approach given by mongo README help file

RUNNING

For command line options invoke:

$ ./mongod --help

To run a single server database:

$ sudo mkdir -p /data/db
$ ./mongod
$
$ # The mongo javascript shell connects to localhost and test database by default:
$ ./mongo
> help

If you are working with windows, go to your directory where you have mongo.exe

use the following commands, (I am sharing mine)

C:\Program Files\MongoDB\Server\3.6\bin>mkdir \data

C:\Program Files\MongoDB\Server\3.6\bin>mkdir \data\db

C:\Program Files\MongoDB\Server\3.6\bin>mongod ## this will start your mongoDB server

Now you need to run another CMD prompt and go to the directory where you have mongo and just run it

C:\Program Files\MongoDB\Server\3.6\bin>mongo ## this will start your mongoDB client

Hope it helped :)

If it doesn't work, run CMD as an administrator

Quoted from https://developer.mozilla.org/en/DOM/element.click

The click method is intended to be used with INPUT elements of type button, checkbox, radio, reset or submit. Gecko does not implement the click method on other elements that might be expected to respond to mouse–clicks such as links (A elements), nor will it necessarily fire the click event of other elements.

Non–Gecko DOMs may behave differently.

Unfortunately it sounds like you have already discovered the best solution to your problem.

As a side note, I agree that your solution seems less than ideal, but if you encapsulate the functionality inside a method (much like JQuery would do) it is not so bad.

I had some strings in the MongoDB Stored wich had to be reformated to a proper and valid dateTime field in the mongodb.

here is my code for the special date format: "2014-03-12T09:14:19.5303017+01:00"

but you can easyly take this idea and write your own regex to parse the date formats:

// format: "2014-03-12T09:14:19.5303017+01:00"
var myregexp = /(....)-(..)-(..)T(..):(..):(..)\.(.+)([\+-])(..)/;

db.Product.find().forEach(function(doc) { 
   var matches = myregexp.exec(doc.metadata.insertTime);

   if myregexp.test(doc.metadata.insertTime)) {
       var offset = matches[9] * (matches[8] == "+" ? 1 : -1);
       var hours = matches[4]-(-offset)+1
       var date = new Date(matches[1], matches[2]-1, matches[3],hours, matches[5], matches[6], matches[7] / 10000.0)
       db.Product.update({_id : doc._id}, {$set : {"metadata.insertTime" : date}})
       print("succsessfully updated");
    } else {
        print("not updated");
    }
})

You can parse the pom file with JDOM (http://www.jdom.org/).

If you prefer utility classes to regexes, there is a method trimAllWhitespace(String) in StringUtils in the Spring Framework.

Just add in: border-bottom: none;

#index-03 {
    position:absolute;
    border: .1px solid #900;
    border-bottom: none;
    left:0px;
    top:102px;
    width:900px;
    height:27px;
}

This technique uses the Background property to show / hide placeholder textbox.
Placeholder is shown event when Textbox has the focus

How it works:

• When empty, TextBox background set to Transparent to show PlaceHolder text.
• When not empty background set to White to cover up PlaceHolder text.

Here is basic example. For my own purposes I turned this into a UserControl.

<Grid>
    <Grid.Resources>
        <ux:NotEmptyConverter x:Key="NotEmptyConverter" />

        <Style TargetType="{x:Type Control}" x:Key="DefaultStyle">
            <Setter Property="FontSize" Value="20" />
            <Setter Property="Margin" Value="10"/>
            <Setter Property="VerticalAlignment" Value="Center"></Setter>
            <Setter Property="VerticalContentAlignment" Value="Center"></Setter>
        </Style>

        <Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource DefaultStyle}"></Style>

    </Grid.Resources>

    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <TextBox Grid.Row="0" Text="Placeholder Text Is Here" Foreground="DarkGray" />
    <TextBox Grid.Row="0" Name="TextBoxEdit" 
            Text="{Binding Path=FirstName, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" >
        <TextBox.Style>
            <Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource DefaultStyle}">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding Path=FirstName.Length, FallbackValue=0, TargetNullValue=0}" Value="0">
                        <Setter Property="Background" Value="Transparent"/>
                    </DataTrigger>
                    <DataTrigger Binding="{Binding Path=FirstName, FallbackValue=0, TargetNullValue=0, Converter={StaticResource NotEmptyConverter}}" Value="false">
                        <Setter Property="Background" Value="White"/>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </TextBox.Style>
    </TextBox>
</Grid>

Here is the ValueConverter to detect non-empty strings in the DataTrigger.

public class NotEmptyConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        var s = value as string;
        return string.IsNullOrEmpty(s);
    }
    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return null;
    }
}

Sometime we need to compile one single file out of thousand files to fix the problem. In such a case, One can create same folder structure like class path, decompile the file into java or copy java file from source code. Make required changes, compile one particular file into class with all dependency/classes in place and finally replace the class file. Finally restart the container. Once war is exploded file will not be replaced.
