I had this problem I iOS 12.4 when calling evaluateJavascript. I solved it by wrapping the call in DispatchQueue.main.async { }

Some additional advice for Windows(10) users:

1. If you are using Anaconda Prompt/PowerShell for the first time, type "Anaconda" in the search field of your Windows task bar and you will see the suggested software.
2. Make sure to open the Anaconda prompt as administrator.
3. Always navigate to your user directory or the directory with your Jupyter Notebook files first before running the command. Otherwise you might end up somewhere in your system files and be confused by an unfamiliar file tree.

The correct way to open Jupyter notebook with new data limit from the Anaconda Prompt on my own Windows 10 PC is:

(base) C:\Users\mobarget\Google Drive\Jupyter Notebook>jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10

Update: this answer works with both ,Visual Sudio 2017 and 2019

For me it worked by the following three steps:

1. Updating Visual Studio to the latest build.
2. Adding Report / Report Wizard to the Add/New Item menu by:
   • Going to Visual Studio menu Tools/Extensions and Updates
   • Choose Online from the left panel.
   • Search for Microsoft Rdlc Report Designer for Visual Studio
   • Download and install it.

3. Adding Report viewer control by:

   • Going to NuGet Package Manager.

   • Installing Microsoft.ReportingServices.ReportViewerControl.Winforms

   • Go to the folder that contains Microsoft.ReportViewer.WinForms.dll: %USERPROFILE%\.nuget\packages\microsoft.reportingservices.reportviewercontrol.winforms\140.1000.523\lib\net40
   • Drag the Microsoft.ReportViewer.WinForms.dll file and drop it at Visual Studio Toolbox Window.

For WebForms applications:

1. The same.
2. The same.

3. Adding Report viewer control by:

   • Going to NuGet Package Manager.

   • Installing Microsoft.ReportingServices.ReportViewerControl.WebForms

   • Go to the folder that contains Microsoft.ReportViewer.WebForms.dll file: %USERPROFILE%\.nuget\packages\microsoft.reportingservices.reportviewercontrol.webforms\140.1000.523\lib\net40
   • Drag the Microsoft.ReportViewer.WebForms.dll file and drop it at Visual Studio Toolbox Window.

That's all!

You can do this using a combination of existing Collection methods. It may be a little hard to follow at first, but it should be easy enough to break down.

// get your main collection with all the attributes...
$users = Users::get();

// build your second collection with a subset of attributes. this new
// collection will be a collection of plain arrays, not Users models.
$subset = $users->map(function ($user) {
    return collect($user->toArray())
        ->only(['id', 'name', 'email'])
        ->all();
});

Explanation

First, the map() method basically just iterates through the Collection, and passes each item in the Collection to the passed in callback. The value returned from each call of the callback builds the new Collection generated by the map() method.

collect($user->toArray()) is just building a new, temporary Collection out of the Users attributes.

->only(['id', 'name', 'email']) reduces the temporary Collection down to only those attributes specified.

->all() turns the temporary Collection back into a plain array.

Put it all together and you get "For each user in the users collection, return an array of just the id, name, and email attributes."

Laravel 5.5 update

Laravel 5.5 added an only method on the Model, which basically does the same thing as the collect($user->toArray())->only([...])->all(), so this can be slightly simplified in 5.5+ to:

// get your main collection with all the attributes...
$users = Users::get();

// build your second collection with a subset of attributes. this new
// collection will be a collection of plain arrays, not Users models.
$subset = $users->map(function ($user) {
    return $user->only(['id', 'name', 'email']);
});

If you combine this with the "higher order messaging" for collections introduced in Laravel 5.4, it can be simplified even further:

// get your main collection with all the attributes...
$users = Users::get();

// build your second collection with a subset of attributes. this new
// collection will be a collection of plain arrays, not Users models.
$subset = $users->map->only(['id', 'name', 'email']);

Somehow I had the wrong versions of the DLLs registered in my project.

• I removed the three references to the Crystal Report dlls from my project.
• I right click References, and click Add Reference
• In the popup window, I click the Browse menu on the left and the Browse button
• In the Directory window where your DLLs reside (perhaps your application's bin directory), select the three Crystal Reports DLLs and then click Add.
• Back at the Reference Manager window, click in the first column to the left of the three Crystal dlls, and then click OK
• At this point your Crystal Reports should work again.

I got this error when I was missing a closing brace in a component method:

const Whoops = props => {
  const wonk = () => {props.wonk();      // <- note missing } brace!
  return (
    <View onPress={wonk} />
  )
}

I had the same error. The problem was in the export and import of the modules.

Example of my solution:

Controller (File: posts.js)

exports.getPosts = (req, res) => {
    res.json({
        posts: [
            { tittle: 'First posts' },
            { tittle: 'Second posts' },
        ]
    });
};

Router (File: posts.js)

const express = require('express');
const { getPosts } = require('../controllers/posts');

const routerPosts = express.Router();
routerPosts.get('/', getPosts);

exports.routerPosts = routerPosts;

Main (File: app.js)

const express = require('express');
const morgan = require('morgan');
const dotenv = require('dotenv');
const { routerPosts } = require('./routes/posts');

const app = express();
const port = process.env.PORT || 3000;

dotenv.config();

// Middleware
app.use(morgan('dev'));

app.use('/', routerPosts);

app.listen(port, () => {
    console.log(`A NodeJS API is listining on port: ${port}`);
});

Running the application (chrome output)

// 20200409002022
// http://localhost:3000/

{
  "posts": [
    {
      "tittle": "First posts"
    },
    {
      "tittle": "Second posts"
    }
  ]
}

I have solved this problem, please just make few changes

1- all controller class name should start with capital letter. i mean first letter of class should be capital . eg we have controler with class name Pages

so it should be Pages not pages

2- save the controller class Pages as Pages.php not pages.php

so first letter must be capital

same for model, model class first letter should be capital and also save model class as Pages_model.php not page_model.php

hope this will solve ur problem

Do the following steps to resolve the issue

In Storyboard, select any view, then go to the File inspector. Uncheck the "Use Size Classes", you will ask to keep size class data for: iPhone/iPad. And then Click the "Disable Size Classes" button. Doing this will make the storyboard's view size with selected device.

I had to change the js file, so to include "function()" at the beginning of it, and also "()" at the end line. That solved the problem

If a credit card is already added to a PayPal account then it won't let you use that card to process directly with Payments Advanced. The system expects buyers to login to PayPal and just choose that credit card as their funding source if they want to pay with it.

As for testing on the sandbox, I've always used old, expired credit cards I have laying around and they seem to work fine for me.

You could always try the ones starting on page 87 of the PayFlow documentation, too. They should work.

It was because I had turned off "Logs" in the list of boxes earlier.

Try this out.

I think the answer is a mix of your question and this answer here: https://stackoverflow.com/a/15931345/734687 So I would try the following code:

1. change ACTION_VIEW to ACTION_SENDTO
2. set the Uri as you did
3. set the package to whatsapp

Intent i = new Intent(Intent.ACTION_SENDTO, Uri.parse("content://com.android.contacts/data/" + c.getString(0)));
i.setType("text/plain");
i.setPackage("com.whatsapp");           // so that only Whatsapp reacts and not the chooser
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT, "I'm the body.");
startActivity(i);

I looked into the Whatsapp manifest and saw that ACTION_SEND is registered to the activity ContactPicker, so that will not help you. However ACTION_SENDTO is registered to the activity com.whatsapp.Conversation which sounds more adequate for your problem.

Whatsapp can work as a replacement for sending SMS, so it should work like SMS. When you do not specify the desired application (via setPackage) Android displays the application picker. Thererfor you should just look at the code for sending SMS via intent and then provide the additional package information.

Uri uri = Uri.parse("smsto:" + smsNumber);
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.putExtra("sms_body", smsText);  
i.setPackage("com.whatsapp");  
startActivity(i);

First try just to replace the intent ACTION_SEND to ACTION_SENDTO . If this does not work than provide the additional extra sms_body. If this does not work than try to change the uri.

Update I tried to solve this myself and was not able to find a solution. Whatsapp is opening the chat history, but doesn't take the text and send it. It seems that this functionality is just not implemented.

It is possible.

Websocket and WebRTC can be used together, Websocket as a signal channel of WebRTC, and webrtc is a video/audio/text channel, also WebRTC can be in UDP also in TURN relay, TURN relay support TCP HTTP also HTTPS. Many projects use Websocket and WebRTC together.

You can use the fingerprintJS2 library, it helps a lot with calculating a browser fingerprint.

By the way, on Panopticlick you can see how unique this usually is.

just simple:

.navbar{
    width:65% !important;
    margin:0px auto;
    left:0;
    right:0;
    padding:0;
}

or,

.navbar.navbar-fixed-top{
    width:65% !important;
    margin:0px auto;
    left:0;
    right:0;
    padding:0;
}

Hope it works (at least, for future searchers)

You have to move the css folder into your web folder. It seems that your web folder on the hard drive equals the /ServletApp folder as seen from the www. Other content than inside your web folder cannot be accessed from the browsers.

The url of the CSS link is then

 <link rel="stylesheet" type="text/css" href="/ServletApp/css/styles.css"/>

Because your update uses PUT method, {entryId: $scope.entryId} is considered as data, to tell angular generate from the PUT data, you need to add params: {entryId: '@entryId'} when you define your update, which means

return $resource('http://localhost\\:3000/realmen/:entryId', {}, {
  query: {method:'GET', params:{entryId:''}, isArray:true},
  post: {method:'POST'},
  update: {method:'PUT', params: {entryId: '@entryId'}},
  remove: {method:'DELETE'}
});

Fix: Was missing a closing curly brace on the update line.

Know your host ip address on your lan Open cmd and type ipconfig and the if xampp the default listen port would be 80 Then for instance if 10.0.0.5 is your host ip address Type 10.0.0.5:80 from your mobile's web browser Make sure that both are connected to the same LAN However the default port that webaddress tries is 80.

After reading your comment on my previous answer I thought I might put this as a separate answer.

Although I appreciate your approach of trying to do it manually to get a better grasp on jQuery I do still emphasise the merit in using existing frameworks.

That said, here is a solution. I've modified some of your css and and HTML just to make it easier for me to work with

WORKING JS FIDDLE - http://jsfiddle.net/HsEne/15/

This is the jQuery

$(document).ready(function(){
$('.sp').first().addClass('active');
$('.sp').hide();    
$('.active').show();

    $('#button-next').click(function(){

    $('.active').removeClass('active').addClass('oldActive');    
                   if ( $('.oldActive').is(':last-child')) {
        $('.sp').first().addClass('active');
        }
        else{
        $('.oldActive').next().addClass('active');
        }
    $('.oldActive').removeClass('oldActive');
    $('.sp').fadeOut();
    $('.active').fadeIn();


    });

       $('#button-previous').click(function(){
    $('.active').removeClass('active').addClass('oldActive');    
           if ( $('.oldActive').is(':first-child')) {
        $('.sp').last().addClass('active');
        }
           else{
    $('.oldActive').prev().addClass('active');
           }
    $('.oldActive').removeClass('oldActive');
    $('.sp').fadeOut();
    $('.active').fadeIn();
    });




});

So now the explanation.
Stage 1
1) Load the script on document ready.

2) Grab the first slide and add a class 'active' to it so we know which slide we are dealing with.

3) Hide all slides and show active slide. So now slide #1 is display block and all the rest are display:none;

Stage 2 Working with the button-next click event.
1) Remove the current active class from the slide that will be disappearing and give it the class oldActive so we know that it is on it's way out.

2) Next is an if statement to check if we are at the end of the slideshow and need to return to the start again. It checks if oldActive (i.e. the outgoing slide) is the last child. If it is, then go back to the first child and make it 'active'. If it's not the last child, then just grab the next element (using .next() ) and give it class active.

3) We remove the class oldActive because it's no longer needed.

4) fadeOut all of the slides

5) fade In the active slides

Step 3

Same as in step two but using some reverse logic for traversing through the elements backwards.

It's important to note there are thousands of ways you can achieve this. This is merely my take on the situation.

Set display.max_rows:

pd.set_option('display.max_rows', 500)

For older versions of pandas (<=0.11.0) you need to change both display.height and display.max_rows.

pd.set_option('display.height', 500)
pd.set_option('display.max_rows', 500)

See also pd.describe_option('display').

You can set an option only temporarily for this one time like this:

from IPython.display import display
with pd.option_context('display.max_rows', 100, 'display.max_columns', 10):
    display(df) #need display to show the dataframe when using with in jupyter
    #some pandas stuff

You can also reset an option back to its default value like this:

pd.reset_option('display.max_rows')

And reset all of them back:

pd.reset_option('all')

When you get a value from client make and that a value for example.

var current_text = document.getElementById('user_text').value;
        var http = new XMLHttpRequest();
        http.onreadystatechange = function () {

            if (http.readyState == 4 &&  http.status == 200 ){
                var response = http.responseText;
              document.getElementById('server_response').value = response;
                console.log(response.value);


            }

This should work

gsub('\u009c','','\u009cYes yes for ever for ever the boys ')
"Yes yes for ever for ever the boys "

Here 009c is the hexadecimal number of unicode. You must always specify 4 hexadecimal digits. If you have many , one solution is to separate them by a pipe:

gsub('\u009c|\u00F0','','\u009cYes yes \u00F0for ever for ever the boys and the girls')

"Yes yes for ever for ever the boys and the girls"

I find that there's simpler solution compared to the accepted answer.

• Read the files using the HTML5 FileReader API with .readAsArrayBuffer
• Create a Blob with the file data and get its url with window.URL.createObjectURL(blob)
• Create new Image element and set it's src to the file blob url
• Send the image to the canvas. The canvas size is set to desired output size
• Get the scaled-down data back from canvas via canvas.toDataURL("image/jpeg",0.7) (set your own output format and quality)
• Attach new hidden inputs to the original form and transfer the dataURI images basically as normal text
• On backend, read the dataURI, decode from Base64, and save it

As per your question:

Is there a way to compress an image (mostly jpeg, png and gif) directly browser-side, before uploading it

My solution:

1. Create a blob with the file directly with URL.createObjectURL(inputFileElement.files[0]).

2. Same as accepted answer.

3. Same as accepted answer. Worth mentioning that, canvas size is necessary and use img.width and img.height to set canvas.width and canvas.height. Not img.clientWidth.

4. Get the scale-down image by canvas.toBlob(callbackfunction(blob){}, 'image/jpeg', 0.5). Setting 'image/jpg' has no effect. image/png is also supported. Make a new File object inside the callbackfunction body with let compressedImageBlob = new File([blob]).

5. Add new hidden inputs or send via javascript . Server doesn't have to decode anything.

Check https://javascript.info/binary for all information. I came up the solution after reading this chapter.

Code:

    <!DOCTYPE html>
    <html>
    <body>
    <form action="upload.php" method="post" enctype="multipart/form-data">
      Select image to upload:
      <input type="file" name="fileToUpload" id="fileToUpload" multiple>
      <input type="submit" value="Upload Image" name="submit">
    </form>
    </body>
    </html>

This code looks far less scary than the other answers..

Update:

One has to put everything inside img.onload. Otherwise canvas will not be able to get the image's width and height correctly as the time canvas is assigned.

    function upload(){
        var f = fileToUpload.files[0];
        var fileName = f.name.split('.')[0];
        var img = new Image();
        img.src = URL.createObjectURL(f);
        img.onload = function(){
            var canvas = document.createElement('canvas');
            canvas.width = img.width;
            canvas.height = img.height;
            var ctx = canvas.getContext('2d');
            ctx.drawImage(img, 0, 0);
            canvas.toBlob(function(blob){
                    console.info(blob.size);
                    var f2 = new File([blob], fileName + ".jpeg");
                    var xhr = new XMLHttpRequest();
                    var form = new FormData();
                    form.append("fileToUpload", f2);
                    xhr.open("POST", "upload.php");
                    xhr.send(form);
            }, 'image/jpeg', 0.5);
        }
    }

I have same problem and i found solution which is given below with full datepicker using simple HTML,Javascript and CSS. In this code i prepare formate like dd/mm/yyyy but you can work any.

HTML Code:

    <body>
<input type="date" id="dt" onchange="mydate1();" hidden/>
<input type="text" id="ndt"  onclick="mydate();" hidden />
<input type="button" Value="Date" onclick="mydate();" />
</body>

CSS Code:

#dt{text-indent: -500px;height:25px; width:200px;}

Javascript Code :

function mydate()
{
  //alert("");
document.getElementById("dt").hidden=false;
document.getElementById("ndt").hidden=true;
}
function mydate1()
{
 d=new Date(document.getElementById("dt").value);
dt=d.getDate();
mn=d.getMonth();
mn++;
yy=d.getFullYear();
document.getElementById("ndt").value=dt+"/"+mn+"/"+yy
document.getElementById("ndt").hidden=false;
document.getElementById("dt").hidden=true;
}

Output:

Ensure that you are using Attributes (e.g. RequiredAttribute) which comes under System.ComponentModel.DataAnnotations namespace

You can check the android VLC it can stream and play video, if you want to indagate more, you can check their GIT to analyze what their do. Good luck!

By writing your client code in terms of iterators you abstract away the container completely.

Consider this code:

class ExpressionParser // some generic arbitrary expression parser
{
public:
    template<typename It>
    void parse(It begin, const It end)
    {
        using namespace std;
        using namespace std::placeholders;
        for_each(begin, end, 
            bind(&ExpressionParser::process_next, this, _1);
    }
    // process next char in a stream (defined elsewhere)
    void process_next(char c);
};

client code:

ExpressionParser p;

std::string expression("SUM(A) FOR A in [1, 2, 3, 4]");
p.parse(expression.begin(), expression.end());

std::istringstream file("expression.txt");
p.parse(std::istringstream<char>(file), std::istringstream<char>());

char expr[] = "[12a^2 + 13a - 5] with a=108";
p.parse(std::begin(expr), std::end(expr));

Edit: Consider your original code example, implemented with :

using namespace std;

vector<int> myIntVector;
// Add some elements to myIntVector
myIntVector.push_back(1);
myIntVector.push_back(4);
myIntVector.push_back(8);

copy(myIntVector.begin(), myIntVector.end(), 
    std::ostream_iterator<int>(cout, " "));

A better solution for your problem might be the Charts library. It enables you to use the excellent Highcharts javascript library to make beautiful and interactive plots. Highcharts uses the HTML svg tag so all your charts are actually vector images.

Some features:

• Vector plots which you can download in .png, .jpg and .svg formats so you will never run into resolution problems
• Interactive charts (zoom, slide, hover over points, ...)
• Usable in an IPython notebook
• Explore hundreds of data structures at the same time using the asynchronous plotting capabilities.

Disclaimer: I'm the developer of the library

• This will unstage all files you might have staged with git add:

  git reset
  

• This will revert all local uncommitted changes (should be executed in repo root):

  git checkout .
  

  You can also revert uncommitted changes only to particular file or directory:

  git checkout [some_dir|file.txt]
  

  Yet another way to revert all uncommitted changes (longer to type, but works from any subdirectory):

  git reset --hard HEAD
  

• This will remove all local untracked files, so only git tracked files remain:

  git clean -fdx
  

  WARNING: -x will also remove all ignored files, including ones specified by .gitignore! You may want to use -n for preview of files to be deleted.

To sum it up: executing commands below is basically equivalent to fresh git clone from original source (but it does not re-download anything, so is much faster):

git reset
git checkout .
git clean -fdx

Typical usage for this would be in build scripts, when you must make sure that your tree is absolutely clean - does not have any modifications or locally created object files or build artefacts, and you want to make it work very fast and to not re-clone whole repository every single time.

git isn't a centralized scm like svn so you have two options:

• Use the web interface of target platforms (f.e. GitHub REST API or GitLab REST API)
• Download the repository and display logs locally

It may be annoying to implement for many different platforms (GitHub, GitLab, BitBucket, SourceForge, Launchpad, Gogs, ...) but fetching data is pretty slow (we talk about seconds) - no solution is perfect.

An example with fetching into a temporary directory:

git clone https://github.com/rust-lang/rust.git -b master --depth 3 --bare --filter=blob:none -q .
git log -n 3 --no-decorate --format=oneline

Alternatively:

git init --bare -q
git remote add -t master origin https://github.com/rust-lang/rust.git
git fetch --depth 3 --filter=blob:none -q
git log -n 3 --no-decorate --format=oneline origin/master

Both are optimized for performance by restricting to exactly 3 commits of one branch into a minimal local copy without file contents and preventing console outputs. Though opening a connection and calculating deltas during fetch takes some time.

An example with GitHub:

GET https://api.github.com/repos/rust-lang/rust/commits?sha=master&per_page=3

An example with GitLab:

GET https://gitlab.com/api/v4/projects/inkscape%2Finkscape/repository/commits?ref_name=master&per_page=3

Both are really fast but have different interfaces (like every platform).

html:

<form method="post" name="form1" id="form1">    
    <input id="submit" name="submit" type="submit" value="Submit" onclick="eatFood();" />
</form>

Javascript: to submit the form using javascript

function eatFood() {
document.getElementById('form1').submit();

You can use Eclipse DDMS perspective to see connected devices and browse through files, you can also pull and push files to the device. You can also do a bunch of stuff using DDMS, this link explains a little bit more of DDMS uses.

EDIT:

If you just want to copy a database you can locate the database on eclipse DDMS file explorer, select it and then pull the database from the device to your computer.

If you need one-off sync with the solution pane, then there is new command "Sync with Active Document" (default shortcut: Ctrl+[, S). Explained here: Visual Studio 2012 New Features: Solution Explorer

The approach I have taken is to just throw exceptions from the api controller actions and have an exception filter registered that processes the exception and sets an appropriate response on the action execution context.

The filter exposes a fluent interface that provides a means of registering handlers for specific types of exceptions prior to registering the filter with global configuration.

The use of this filter enables centralized exception handling instead of spreading it across the controller actions. There are however cases where I will catch exceptions within the controller action and return a specific response if it does not make sense to centralize the handling of that particular exception.

Example registration of filter:

GlobalConfiguration.Configuration.Filters.Add(
    new UnhandledExceptionFilterAttribute()
    .Register<KeyNotFoundException>(HttpStatusCode.NotFound)

    .Register<SecurityException>(HttpStatusCode.Forbidden)

    .Register<SqlException>(
        (exception, request) =>
        {
            var sqlException = exception as SqlException;

            if (sqlException.Number > 50000)
            {
                var response            = request.CreateResponse(HttpStatusCode.BadRequest);
                response.ReasonPhrase   = sqlException.Message.Replace(Environment.NewLine, String.Empty);

                return response;
            }
            else
            {
                return request.CreateResponse(HttpStatusCode.InternalServerError);
            }
        }
    )
);

There is a documentation in SLf4J site to resolve this. I followed that and added slf4j-simple-1.6.1.jar to my aplication along with slf4j-api-1.6.1.jar which i already had.This solved my problem

PowerShell Alternative

This is an old post and I read through the answers. Still, I found it a bit too painful to output multi-line large text fields unaltered from SSMS. I ended up writing a small C# program for my needs, but got to thinking it could probably be done using the command line. Turns out, it is fairly easy to do so with PowerShell.

Start by installing the SqlServer module from an administrative PowerShell.

Install-Module -Name SqlServer

Use Invoke-Sqlcmd to run your query:

$Rows = Invoke-Sqlcmd -Query "select BigColumn from SomeTable where Id = 123" `
    -As DataRows -MaxCharLength 1000000 -ConnectionString $ConnectionString

This will return an array of rows that you can output to the console as follows:

$Rows[0].BigColumn

Or output to a file as follows:

$Rows[0].BigColumn | Out-File -FilePath .\output.txt -Encoding UTF8

The result is a beautiful un-truncated text written to a file for viewing/editing. I am sure there is a similar command to save back the text to SQL Server, although that seems like a different question.

EDIT: It turns out that there was an answer by @dvlsc that described this approach as a secondary solution. I think because it was listed as a secondary answer, is the reason I missed it in the first place. I am going to leave my answer which focuses on the PowerShell approach, but wanted to at least give credit where it was due.

The problem is caused because the code is accessing a lazy JPA relation when the "connection" to the database is closed (persistence context is the correct name in terms of Hibernate/JPA).

A simple way of solving it in Spring Boot is by defining a service layer and using the @Transactional annotation. This annotation in a method creates a transaction that propagates into the repository layer and keeps open the persistence context until the method finish. If you access the collection inside the transactional method Hibernate/JPA will fetch the data from the database.

In your case, you just need to annotate with @Transactional the method findTopicByID(id) in your TopicService and force the fetch of the collection in that method (for instance, by asking its size):

    @Transactional(readOnly = true)
    public Topic findTopicById(Long id) {
        Topic topic = TopicRepository.findById(id).orElse(null);
        topic.getComments().size();
        return topic;
    }

Add to your JS:

jQuery(document).ready(function($) {
  $("body").css({
    'padding-top': $(".navbar").outerHeight() + 'px'
  })
});

Just push to the branch that the pull request references. As long as the pull request is still open, it should get updated with any added commits automatically.

With shortcuts available, the quickest way is to

1. Open the Developer Tools

   • Windows: F12 or Ctrl+Shift+I
   • Mac: Cmd+Opt+I

2. Open the Command Menu

   • Windows: Ctrl+Shift+P
   • Mac: Cmd+Shift+P

3. Type print and select Emulate CSS print media type from the context menu

   

Looking at the excellent and currently most-upvoted answer by lmeurs, I think this solution might also remain stable over time.

In IE11, you can see local storage in console on dev tools:

1. Show dev tools (press F12)
2. Click "Console" or press Ctrl+2
3. Type localStorage and press Enter

Also, if you need to clear the localStorage, type localStorage.clear() on console.

An example of where the console will return ReferenceError is putting a function inside a JQuery document ready function

//this will fail
$(document).ready(function () {
          myFunction(alert('doing something!'));
          //other stuff
}

To succeed move the function outside the document ready function

//this will work
myFunction(alert('doing something!'));
$(document).ready(function () {

          //other stuff
}

Then in the console window, type the function name with the '()' to execute the function

myFunction()

Also of use is being able to print out the function body to remind yourself what the function does. Do this by leaving off the '()' from the function name

function myFunction(alert('doing something!'))

Of course if you need the function to be registered after the document is loaded then you couldn't do this. But you might be able to work around that.

You can use .scrollIntoView() for this. It will bring a specific element into the viewport.

Example:

document.getElementById( 'bottom' ).scrollIntoView();

Demo: http://jsfiddle.net/ThinkingStiff/DG8yR/

Script:

function top() {
    document.getElementById( 'top' ).scrollIntoView();    
};

function bottom() {
    document.getElementById( 'bottom' ).scrollIntoView();
    window.setTimeout( function () { top(); }, 2000 );
};

bottom();

HTML:

<div id="top">top</div>
<div id="bottom">bottom</div>

CSS:

#top {
    border: 1px solid black;
    height: 3000px;
}

#bottom {
    border: 1px solid red;
}

see: https://developer.mozilla.org/en-US/docs/Web/CSS/cursor

so you need to add: cursor:pointer;

In your case use:

#more {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

This will apply the curser to the element with the ID "more" (can be only used once). So in your HTML use

<input type="button" id="more" />

If you want to apply this to more than one button then you have more than one possibility:

using CLASS

.more {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

and in your HTML use

<input type="button" class="more" value="first" />
<input type="button" class="more" value="second" />

or apply to a html context:

input[type=button] {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

and in your HTML use

<input type="button" value="first" />
<input type="button" value="second" />

You can use from root directory:

RewriteEngine On
RewriteRule ^(?:system)\b.* /403.html

Or:

RewriteRule ^(?:system)\b.* /403.php # with header('HTTP/1.0 403 Forbidden');

On Mac OS you have to press: CMD+ALT+I

Unfortunately the native browser present on Android devices not support this type of file. Let's see if in the 4.0 we will be able to do that.

For HSQLDB, The following worked for me:

DatabaseManager.threadedDBM();

And this brought up the GUI with my tables and data once I pointed it to the right named in-mem database.

It is basically the equivalent of newing up a DatabaseManager (the non Swing variety), which prompts for connection details, and is set to --noexit)

I also tried the Swing version, but it only had a main, and I was unsure of the arguments to pass. If anyone knows, please post here.

Just because I searched for hours for the right database name: The name of the database is the name of your datasource. So try with URL jdbc:hsqldb:mem:dataSource if you have a data source bean with id=dataSource. If this does not work, try testdb which is the default.

i had this problem, and resolved it editing httd.conf

<IfModule headers_module>
    <IfVersion >= 2.4.7 >
        Header always setifempty X-Frame-Options GOFORIT
    </IfVersion>
    <IfVersion < 2.4.7 >
        Header always merge X-Frame-Options GOFORIT
    </IfVersion>
</IfModule>

i changed SAMEORIGIN to GOFORIT and restarted server

If you want a variable to be accessible across the entire page, it works well to define it at the top of the file. (You can use either an implicit or explicit type.)

@{
    // implicit type
    var something1 = "something";

    // explicit type
    string something2 = "something";
}

<div>@something1</div> @*display first variable*@
<div>@something2</div> @*display second variable*@

This solution only for chrome browser. I am not sure about other browser.

1. Add "Modify Content-Type Options" extension in chrome browser.
2. Open "chrome-extension://jnfofbopfpaoeojgieggflbpcblhfhka/options.html" url in browser.
3. Add the rule for raw file url. For example:
   • URL Filter: https:///raw/master//fileName.html
   • Original Type: text/plain
   • Replacement Type: text/html
4. Open the file browser which you added url in rule (in step 3).

If the bandwidth is far higher than the bitrate, I would recommend TCP for unicast live video streaming.

Case 1: Consecutive packets are lost for a duration of several seconds. => live video will stop on the client side whatever the transport layer is (TCP or UDP). When the network recovers: - if TCP is used, client video player can choose to restart the stream at the first packet lost (timeshift) OR to drop all late packets and to restart the video stream with no timeshift. - if UDP is used, there is no choice on the client side, video restart live without any timeshift. => TCP equal or better.

Case 2: some packets are randomly and often lost on the network. - if TCP is used, these packets will be immediately retransmitted and with a correct jitter buffer, there will be no impact on the video stream quality/latency. - if UDP is used, video quality will be poor. => TCP much better

In my case, database returned latin1, when my browser expected utf8.

So for MySQLi I did:

 mysqli_set_charset($dblink, "utf8");

This what I have found for fixing orientation issue

UIImage *initialImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
NSData *data = UIImagePNGRepresentation(self.initialImage);

UIImage *tempImage = [UIImage imageWithData:data];
UIImage *fixedOrientationImage = [UIImage imageWithCGImage:tempImage.CGImage
                                     scale:initialImage.scale
                               orientation:self.initialImage.imageOrientation];
initialImage = fixedOrientationImage;

EDIT:

UIImage *initialImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
NSData *data = UIImagePNGRepresentation(self.initialImage);

initialImage = [UIImage imageWithCGImage:[UIImage imageWithData:data].CGImage
                                                     scale:initialImage.scale
                                               orientation:self.initialImage.imageOrientation];

There is a very good answer to the same question.
Adding following lines to "~/.gitconfig":

[alias]
lg1 = log --graph --abbrev-commit --decorate --date=relative --format=format:'%C(bold blue)%h%C(reset) - %C(bold green)(%ar)%C(reset) %C(white)%s%C(reset) %C(dim white)- %an%C(reset)%C(bold yellow)%d%C(reset)' --all
lg2 = log --graph --abbrev-commit --decorate --format=format:'%C(bold blue)%h%C(reset) - %C(bold cyan)%aD%C(reset) %C(bold green)(%ar)%C(reset)%C(bold yellow)%d%C(reset)%n''          %C(white)%s%C(reset) %C(dim white)- %an%C(reset)' --all
lg = !"git lg1"

if(window.innerHeight > window.innerWidth){
    alert("Please use Landscape!");
}

jQuery Mobile has an event that handles the change of this property... if you want to warn if someone rotates later - orientationchange

Also, after some googling, check out window.orientation (which is I believe measured in degrees...)

EDIT: On mobile devices, if you open a keyboard then the above may fail, so can use screen.availHeight and screen.availWidth, which gives proper height and width even after the keyboard is opened.

if(screen.availHeight > screen.availWidth){
    alert("Please use Landscape!");
}

ALTER TABLE table_name CONVERT to CHARACTER SET utf8;

System.Diagnostics.Process.Start("SOMEAPP.EXE","Path/SomeFile.Ext");

[System.Runtime.InteropServices.DllImport("shell32. dll")]
private static extern long ShellExecute(Int32 hWnd, string lpOperation, 
                                    string lpFile, string lpParameters, 
                                        string lpDirectory, long nShowCmd);

Another approach is to place a WebBrowser Control into your Form and then use the Navigate method for opening the PDF file:

ThewebBrowserControl.Navigate(@"c:\the_file.pdf");

if you want to always use git log in such way you could add git alias by

git config --global alias.log log --oneline

after that git log will print what normally would be printed by git log --oneline

Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).

You need to do a deep equals.

From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.

Object.extend(Object, {
   deepEquals: function(o1, o2) {
     var k1 = Object.keys(o1).sort();
     var k2 = Object.keys(o2).sort();
     if (k1.length != k2.length) return false;
     return k1.zip(k2, function(keyPair) {
       if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
         return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
       } else {
         return o1[keyPair[0]] == o2[keyPair[1]];
       }
     }).all();
   }
});

Usage:

var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);

if (Object.deepEquals(anObj, anotherObj))
   ...

You can also add prompt option like this.

<%= f.select(:object_field, ['Item 1', 'Item 2'], {include_blank: "Select something"}, { :class => 'my_style_class' }) %>

I answer this topic just in case someone read it and is interested on the result. It is possible to view a video element (video html5 tag) within a WebView, but I must say I had to deal with it for few days. These are the steps I had to follow so far:

-Find a properly encoded video

-When initializing the WebView, set the JavaScript, Plug-ins the WebViewClient and the WebChromeClient.

url = new String("http://broken-links.com/tests/video/"); 
mWebView = (WebView) findViewById(R.id.webview);
mWebView.setWebChromeClient(chromeClient);
mWebView.setWebViewClient(wvClient);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setPluginState(PluginState.ON);
mWebView.loadUrl(url);

-Handle the onShowCustomView in the WebChromeClient object.

@Override
public void onShowCustomView(View view, CustomViewCallback callback) {
    super.onShowCustomView(view, callback);
    if (view instanceof FrameLayout){
        FrameLayout frame = (FrameLayout) view;
        if (frame.getFocusedChild() instanceof VideoView){
            VideoView video = (VideoView) frame.getFocusedChild();
            frame.removeView(video);
            a.setContentView(video);
            video.setOnCompletionListener(this);
            video.setOnErrorListener(this);
            video.start();
        }
    }
}

-Handle the onCompletion and the onError events for the video, in order to get back to the web view.

public void onCompletion(MediaPlayer mp) {
    Log.d(TAG, "Video completo");
    a.setContentView(R.layout.main);
    WebView wb = (WebView) a.findViewById(R.id.webview);
    a.initWebView();
}

But now I should say there are still an important issue. I can play it only once. The second time I click on the video dispatcher (either the poster or some play button), it does nothing.

I would also like the video to play inside the WebView frame, instead of opening the Media Player window, but this is for me a secondary issue.

I hope it helps somebody, and I would also thank any comment or suggestion.

Saludos, terrícolas.

For people who want to use another diff tool not listed in git, say with nvim. here is what I ended up using:

git config --global alias.d difftool -x <tool name>

In my case, I set <tool name> to nvim -d and invoke the diff command with

git d <file>

I've been playing around with another option that uses blobs. I've managed to get it to download text documents, and I've downloaded PDF's (However they are corrupted).

Using the blob API you will be able to do the following:

$.post(/*...*/,function (result)
{
    var blob=new Blob([result]);
    var link=document.createElement('a');
    link.href=window.URL.createObjectURL(blob);
    link.download="myFileName.txt";
    link.click();

});

This is IE 10+, Chrome 8+, FF 4+. See https://developer.mozilla.org/en-US/docs/Web/API/URL.createObjectURL

It will only download the file in Chrome, Firefox and Opera. This uses a download attribute on the anchor tag to force the browser to download it.

There's no simple answer to this question. Apple's mobile version of WebKit, used in iPhones, iPod Touches, and iPads, will scale the page to fit the screen, at which point the user can zoom in and out freely.

That said, you can design your page to minimize the amount of zooming necessary. Your best bet is to make the width and height the same as the lower resolution of the iPad, since you don't know which way it's oriented; in other words, you would make your page 768x768, so that it will fit well on the iPad's screen whether it's oriented to be 1024x768 or 768x1024.

More importantly, you'd want to design your page with big controls with lots of space that are easy to hit with your thumbs - you could easily design a 768x768 page that was very cluttered and therefore required lots of zooming. To accomplish this, you'll likely want to divide your controls among a number of web pages.

On the other hand, it's not the most worthwhile pursuit. If while designing you find opportunities to make your page more "finger-friendly", then go for it...but the reality is that iPad users are very comfortable with moving around and zooming in and out of the page to get to things because it's necessary on most web sites. If anything, you probably want to design it so that it's conducive to this type of navigation.

Make boxes with relevant grouped data that can be easily double-tapped to focus on, and keep related controls close to each other. iPad users will most likely appreciate a page that facilitates the familiar zoom-and-pan navigation they're accustomed to more than they will a page that has fewer controls so that they don't have to.

git log origin/master..master

or, more generally:

git log <since>..<until>

You can use this with grep to check for a specific, known commit:

git log <since>..<until> | grep <commit-hash>

Or you can also use git-rev-list to search for a specific commit:

git rev-list origin/master | grep <commit-hash>

Select Help->About

for 64 bit.. it would say version as 64 bit Edition.

I see this in IE 9.. may be true with lesser versions too..

xml:space="preserve" has to work for all compliant XML parsers.

However, note that in HTML the line break is just whitespace and NOT a line break (this is represented with the <br /> (X)HTML tag, maybe this is the problem which you are facing.

You can also add 
 and/or 
 to insert CR/LF characters.

 Control Panel>System and Security>Windows Firewall>Allowed Programs-> then check all " World Wide Web Services(Http) tab". 

Its worked for me

It is likely that you're using a pager such as less or most since the output of ps aux is longer than a screenful. If so, the following options will cause (or force) long lines to wrap instead of being truncated.

ps aux | less -+S

ps aux | most -w

If you use either of the following commands, lines won't be wrapped but you can use your arrow keys or other movement keys to scroll left and right.

ps aux | less -S    # use arrow keys, or Esc-( and Esc-), or Alt-( and Alt-) 

ps aux | most       # use arrow keys, or < and > (Tab can also be used to scroll right)

Lines are always wrapped for more and pg.

When ps aux is used in a pipe, the w option is unnecessary since ps only uses screen width when output is to the terminal.

one way of doing things is to list commits that are available on one branch but not another.

git log ^origin/master master

For Antlr 4 the java code generation process is below:-

java -cp antlr-4.5.3-complete.jar org.antlr.v4.Tool Exp.g

Update your jar name in classpath accordingly.

Somewhere in that mess, the non-breaking spaces from the HTML template (the  s) are encoding as ISO-8859-1 so that they show up incorrectly as an "Â" character

That'd be encoding to UTF-8 then, not ISO-8859-1. The non-breaking space character is byte 0xA0 in ISO-8859-1; when encoded to UTF-8 it'd be 0xC2,0xA0, which, if you (incorrectly) view it as ISO-8859-1 comes out as " ". That includes a trailing nbsp which you might not be noticing; if that byte isn't there, then something else has mauled your document and we need to see further up to find out what.

What's the regexp, how does the templating work? There would seem to be a proper HTML parser involved somewhere if your   strings are (correctly) being turned into U+00A0 NON-BREAKING SPACE characters. If so, you could just process your template natively in the DOM, and ask it to serialise using the ASCII encoding to keep non-ASCII characters as character references. That would also stop you having to do regex post-processing on the HTML itself, which is always a highly dodgy business.

Well anyway, for now you can add one of the following to your document's <head> and see if that makes it look right in the browser:

• for HTML4: <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
• for HTML5: <meta charset="utf-8">

If you've done that, then any remaining problem is ActivePDF's fault.

This has been in the product for years - although it wasn't in the product in 2011.

But, simply click on the Model page.

Make sure you are on at least version 4.0 (released in 2013) to access this feature.

That proof of concept you made was great! However I also found this jQuery plugin which seems to be working very well. Hope it helps!

You can obfuscate it, but there's no way of protecting it completely.

example obfuscator: https://obfuscator.io

You haven't said what language you're using. If it's Perl then it's trivial:

use CGI::Info;

my $info = CGI::Info->new();

if($info->is_mobile()) {
   # Add mobile stuff
}

unless($info->is_mobile()) {
   # Don't do some things on a mobile
}

Use colout program: http://nojhan.github.io/colout/

It is designed to add color highlights to a text stream. Given a regex and a color (e.g. "red"), it reproduces a text stream with matches highlighted. e.g:

# cat logfile but highlight instances of 'ERROR' in red
colout ERROR red <logfile

You can chain multiple invocations to add multiple different color highlights:

tail -f /var/log/nginx/access.log | \
    colout ' 5\d\d ' red | \
    colout ' 4\d\d ' yellow | \
    colout ' 3\d\d ' cyan | \
    colout ' 2\d\d ' green

Or you can achieve the same thing by using a regex with N groups (parenthesised parts of the regex), followed by a comma separated list of N colors.

vagrant status | \
    colout \
        '\''(^.+  running)|(^.+suspended)|(^.+not running)'\'' \
        green,yellow,red

Use get_the_category() like this:

<?php
foreach((get_the_category()) as $category) { 
    echo $category->cat_name . ' '; 
} 
?>

It returns a list because a post can have more than one category.

The documentation also explains how to do this from outside the loop.

If you are using MySQL interactively, you can set your pager to use sed like this:

$ mysql -u <user> p<password>
mysql> pager sed 's/,/\n/g' 
PAGER set to 'sed 's/,/\n/g''
mysql> SELECT blah FROM blah WHERE blah = blah 
.
.
.
"blah":"blah"
"blah":"blah"
"blah":"blah"

If you don't use sed as the pager, the output is like this:

"blah":"blah","blah":"blah","blah":"blah"

You need to escape it with two backslashes

\\?

See this for more details:

One recommendation I've gotten is Hex Fiend.

I think I have a simpler solution here. Just look for a directory whose name corresponds to the PID you are looking for, under the pseudo-filesystem accessible under the /proc path. So if you have a program running, whose ID is 1199, cd into it:

$ cd /proc/1199

Then look for the fd directory underneath

$ cd fd

This fd directory hold the file-descriptors objects that your program is using (0: stdin, 1: stdout, 2: stderr) and just tail -f the one you need - in this case, stdout):

$ tail -f 1

keep in mind dir() will return all current imports, AND variables.

if you just want your variables, I would suggest a naming scheme that is easy to extract from dir, such as varScore, varNames, etc.

that way, you can simply do this:

for vars in dir():
 if vars.startswith("var"):
   print vars

Edit

if you want to list all variables, but exclude imported modules and variables such as:

__builtins__

you can use something like so:

import os
import re

x = 11
imports = "os","re"

for vars in dir():
    if vars.startswith("__") == 0 and vars not in imports:
        print vars

as you can see, it will show the variable "imports" though, because it is a variable (well, a tuple). A quick workaround is to add the word "imports" into the imports tuple itself!

I have to join the chorus recommending log4net, in my case coming from a platform flexibility (desktop .Net/Compact Framework, 32/64-bit) point of view.

However, wrapping it in a private-label API is a major anti-pattern. log4net.ILogger is the .Net counterpart of the Commons Logging wrapper API already, so coupling is already minimized for you, and since it is also an Apache library, that's usually not even a concern because you're not giving up any control: fork it if you must.

Most house wrapper libraries I've seen also commit one or more of a litany of faults:

42. Using a global singleton logger (or equivalently a static entry point) which loses the fine resolution of the recommended logger-per-class pattern for no other selectivity gain.
43. Failing to expose the optional Exception argument, leading to multiple problems:
    • It makes an exception logging policy even more difficult to maintain, so nothing is done consistently with exceptions.
    • Even with a consistent policy, formatting the exception away into a string loses data prematurely. I've written a custom ILayout decorator that performs detailed drill-down on an exception to determine the chain of events.
44. Failing to expose the IsLevelEnabled properties, which discards the ability to skip formatting code when areas or levels of logging are turned off.

What I like doing is overriding ToString() so that I get more useful output beyond the type name. This is handy in the debugger, you can see the information you want about an object without needing to expand it.

You could try JarSpy. There is an IDEA plugin version of it that I use.

There is an extended stored procedure sp_spaceused that gets this information out. It's fairly convoluted to do it from the data dictionary, but This link fans out to a script that does it. This stackoverflow question has some fan-out to information on the underlying data structures that you can use to construct estimates of table and index sizes for capcity planning.

You can try P4Merge.

Visualize the differences between file versions with P4Merge. Resolve conflicts that result from parallel or concurrent development via color coding.

The features includes:

• Highlight and edit text file differences
• Choose to include or ignore line endings or white spaces
• Recognize line-ending conventions for Windows (CRLF), Mac (CR), and Unix (LF)
• Use command-line parameters and launch from non-Perforce applications
• Display line numbers when comparing and merging files
• Exclude files that are modified, unique, or unchanged
• Filter files by name or extension
• Organize modified assets in familiar file/folder hierarchy
• Compare JPEG, GIF, TIFF, BMP, and other file formats
• Extend using the Qt API
• Overlay images or display side-by-side
• Highlight differences on overlaid images

First, disable the currently installed version of Java. To do this, go to Control Panel > Java > Advanced > Default Java for Browsers and uncheck Microsoft Internet Explorer.

Next, enable the version of Java you want to use instead. To do this, go to (for example) C:\Program Files\Java\jre1.5.0_15\bin (where jre1.5.0_15 is the version of Java you want to use), and run javacpl.exe. Go to Advanced > Default Java for Browsers and check Microsoft Internet Explorer.

To get your old version of Java back you need to reverse these steps.

Note that in older versions of Java, Default Java for Browsers is called <APPLET> Tag Support (but the effect is the same).

The good thing about this method is that it doesn't affect other browsers, and doesn't affect the default system JRE.

Ok, so in this application, there is an iframe in which the user is supplied with links or some capacity that allows that iframe to browse to some external site. You are then looking to capture the URL to which the user has browsed.

Something to keep in mind. Since the URL is to an external source, you will be limited in how much you can interact with this iframe via javascript (or an client side access for that matter), this is known as browser cross-domain security, as apparently you have discovered. There are clever work arounds, as presented here Cross-domain, cross-frame Javascript, although I do not think this work around applies in this case.

About all you can access is the location, as you need.

I would suggest making the code presented more resilitant and less error prone. Try browsing the web sometime with IE or FF configured to show javascript errors. You will be surprised just how many javascript errors are thrown, largely because there is a lot of error prone javascript out there, which just continues to proliferate.

This solution assumes that the iframe in question is the same "window" context where you are running the javascript. (Meaning, it is not embedded within another frame or iframe, in which case, the javascript code gets more involved, and you likely need to recursively search through the window hierarchy.)

<iframe name='frmExternal' id='frmExternal' src='http://www.stackoverflow.com'></frame>
<input type='text' id='txtUrl' />
<input type='button' id='btnGetUrl' value='Get URL' onclick='GetIFrameUrl();' />

<script language='javascript' type='text/javascript'>
function GetIFrameUrl()
{
    if (!document.getElementById)
    {
        return;
    }

    var frm = document.getElementById("frmExternal");
    var txt = document.getElementById("txtUrl");

    if (frm == null || txt == null)
    {
        // not great user feedback but slightly better than obnoxious script errors
       alert("There was a problem with this page, please refresh.");
       return;
    }

    txt.value = frm.src;
}
</script>

Hope this helps.

Here's another decoder that works well as of 2014: http://viewstatedecoder.azurewebsites.net/

This worked on an input on which the Ignatu decoder failed with "The serialized data is invalid" (although it leaves the BinaryFormatter-serialized data undecoded, showing only its length).

2019 Update (Read in Full)

Shortcut

Mac: cmd + k

Windows: ctrl + k

TroubleShooting

If the shortcuts do not work for you, the most likely scenario is that either you or an extension you installed has added an open ended ctrl + k / cmd + k chord to another shortcut.

Open ended meaning, the shortcut does not have an explicit when clause that excludes terminal focus. There are two possible solutions here.

Solution 1:

If you added the shortcut, simply go to your keybindings.json file and add a when clause that does not include terminal focus. Example:

{
    "key": "cmd+k cmd+c",
    "command": "someCommandHere",
    "when": "editorTextFocus",
}

Solution 2:

Alternatively, you can add the workbench.action.terminal.clear command to the very bottom of keybindings.json, ensuring it takes precedence over other shortcuts. It'd be wise to add a comment so you don't forget and later place new chords below it. Example:

// Keep this keybinding at very bottom of file to ensure terminal clearing.
{
  "key": "cmd+k",
  "command": "workbench.action.terminal.clear",
  "when": "terminalFocus",
}

For VS2015... here's a VB example for switching from a WebSite project to a Web Application Project that worked for me. None of the other solutions worked for me, which is why I'm sharing this. It's not elegant, but works.

Step 0: Replace all " CodeFile=" with " CodeBehind=" in your project Step 1: Close the Solution. Step 2: Run a home-grown Windows app with the following code (below steps). Step 3: Re-open the solution. Step 4: In Solution Explorer, make sure you are Showing All Files, and search for designer.vb (or designer.cs for C#) Step 5: Select all the missing files, and include them in your project. Step 6: For each file, view the main page / control and save it.

    private void button1_Click(object sender, EventArgs e)
    {
        ProcessDirectory(new DirectoryInfo(textBox1.Text));
    }

    private void ProcessDirectory(DirectoryInfo directory)
    {
        ProcessMask(directory, ".ascx", ".vb");
        ProcessMask(directory, ".aspx", ".vb");

        foreach (DirectoryInfo directoryInfo in directory.GetDirectories())
            ProcessDirectory(directoryInfo);
    }

    private void ProcessMask(DirectoryInfo directory, string maskStart, string maskEnd)
    {
        FileStream fs;
        foreach (FileInfo file in directory.GetFiles(string.Format("*{0}{1}", maskStart, maskEnd)))
        {
            string designerFileName = file.Name.Replace(string.Format("{0}{1}", maskStart, maskEnd), string.Format("{0}.designer{1}", maskStart, maskEnd));
            if (directory.GetFiles(designerFileName).Length == 0)
            {
                using (fs = File.Create(Path.Combine(directory.FullName, designerFileName)))
                {
                    fs.Close();
                }
            }
        }
    }

  });
   </script>

Rails 4.x

When you already have users and uploads tables and wish to add a new relationship between them.

All you need to do is: just generate a migration using the following command:

rails g migration AddUserToUploads user:references

Which will create a migration file as:

class AddUserToUploads < ActiveRecord::Migration
  def change
    add_reference :uploads, :user, index: true
  end
end

Then, run the migration using rake db:migrate. This migration will take care of adding a new column named user_id to uploads table (referencing id column in users table), PLUS it will also add an index on the new column.

UPDATE [For Rails 4.2]

Rails can’t be trusted to maintain referential integrity; relational databases come to our rescue here. What that means is that we can add foreign key constraints at the database level itself and ensure that database would reject any operation that violates this set referential integrity. As @infoget commented, Rails 4.2 ships with native support for foreign keys(referential integrity). It's not required but you might want to add foreign key(as it's very useful) to the reference that we created above.

To add foreign key to an existing reference, create a new migration to add a foreign key:

class AddForeignKeyToUploads < ActiveRecord::Migration
  def change
    add_foreign_key :uploads, :users
  end
end

To create a completely brand new reference with a foreign key(in Rails 4.2), generate a migration using the following command:

rails g migration AddUserToUploads user:references

which will create a migration file as:

class AddUserToUploads < ActiveRecord::Migration
  def change
    add_reference :uploads, :user, index: true
    add_foreign_key :uploads, :users
  end
end

This will add a new foreign key to the user_id column of the uploads table. The key references the id column in users table.

NOTE: This is in addition to adding a reference so you still need to create a reference first then foreign key (you can choose to create a foreign key in the same migration or a separate migration file). Active Record only supports single column foreign keys and currently only mysql, mysql2 and PostgreSQL adapters are supported. Don't try this with other adapters like sqlite3, etc. Refer to Rails Guides: Foreign Keys for your reference.

From Oracle 12c R2 you could use COLLATE operator:

The COLLATE operator determines the collation for an expression. This operator enables you to override the collation that the database would have derived for the expression using standard collation derivation rules.

The COLLATE operator takes one argument, collation_name, for which you can specify a named collation or pseudo-collation. If the collation name contains a space, then you must enclose the name in double quotation marks.

You can compute pairwise cosine similarity on the rows of a sparse matrix directly using sklearn. As of version 0.17 it also supports sparse output:

from sklearn.metrics.pairwise import cosine_similarity
from scipy import sparse

A =  np.array([[0, 1, 0, 0, 1], [0, 0, 1, 1, 1],[1, 1, 0, 1, 0]])
A_sparse = sparse.csr_matrix(A)

similarities = cosine_similarity(A_sparse)
print('pairwise dense output:\n {}\n'.format(similarities))

#also can output sparse matrices
similarities_sparse = cosine_similarity(A_sparse,dense_output=False)
print('pairwise sparse output:\n {}\n'.format(similarities_sparse))

Results:

pairwise dense output:
[[ 1.          0.40824829  0.40824829]
[ 0.40824829  1.          0.33333333]
[ 0.40824829  0.33333333  1.        ]]

pairwise sparse output:
(0, 1)  0.408248290464
(0, 2)  0.408248290464
(0, 0)  1.0
(1, 0)  0.408248290464
(1, 2)  0.333333333333
(1, 1)  1.0
(2, 1)  0.333333333333
(2, 0)  0.408248290464
(2, 2)  1.0

If you want column-wise cosine similarities simply transpose your input matrix beforehand:

A_sparse.transpose()

Try to combine two parts: unique (sequence, counter or date ) and random

public class RandomStringGenerator
{
    public static string Gen()
    {
        return ConvertToBase(DateTime.UtcNow.ToFileTimeUtc()) + GenRandomStrings(5); //keep length fixed at least of one part
    }

    private static string GenRandomStrings(int strLen)
    {
        var result = string.Empty;

        using (var gen = new RNGCryptoServiceProvider())
        {
            var data = new byte[1];

            while (result.Length < strLen)
            {
                gen.GetNonZeroBytes(data);
                int code = data[0];
                if (code > 48 && code < 57 || // 0-9
                    code > 65 && code < 90 || // A-Z
                    code > 97 && code < 122   // a-z
                )
                {
                    result += Convert.ToChar(code);
                }
            }

            return result;
        }
    }

    private static string ConvertToBase(long num, int nbase = 36)
    {
        const string chars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"; //if you wish to make the algorithm more secure - change order of letter here

        // check if we can convert to another base
        if (nbase < 2 || nbase > chars.Length)
            return null;

        int r;
        var newNumber = string.Empty;

        // in r we have the offset of the char that was converted to the new base
        while (num >= nbase)
        {
            r = (int)(num % nbase);
            newNumber = chars[r] + newNumber;
            num = num / nbase;
        }
        // the last number to convert
        newNumber = chars[(int)num] + newNumber;

        return newNumber;
    }
}

Tests:

    [Test]
    public void Generator_Should_BeUnigue1()
    {
        //Given
        var loop = Enumerable.Range(0, 1000);
        //When
        var str = loop.Select(x=> RandomStringGenerator.Gen());
        //Then
        var distinct = str.Distinct();
        Assert.AreEqual(loop.Count(),distinct.Count()); // Or Assert.IsTrue(distinct.Count() < 0.95 * loop.Count())
    }

In likeness of how I found this question using Google, I wanted to take it one step further. Lets say I have a string[] states and a db Entity of StateCounties and I just want the states from the list returned and not all of the StateCounties.

I would write:

db.StateCounties.Where(x => states.Any(s => x.State.Equals(s))).ToList();

I found this within the sample of CheckBoxList for nu-get.

If you want the default colors of Android ICS, you just have to go to your Android SDK and look for this path: platforms\android-15\data\res\values\colors.xml.

Here you go:

<!-- For holo theme -->
    <drawable name="screen_background_holo_light">#fff3f3f3</drawable>
    <drawable name="screen_background_holo_dark">#ff000000</drawable>

This for the Background:

You won't get the same colors if you look this up in Photoshop etc. because they are set up with Alpha values.

I just wanted to add this version because this is such a useful thread and I think this is a very simple implementation. I have used this multiple times in various types if multithreaded application:

 Task.Factory.StartNew(() =>
      {
        DoLongRunningWork();
        Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
              { txt.Text = "Complete"; }));
      });

I think you can try "Google Grid Gallery", it based on aforementioned Masonry with some additions, like styles and viewer.

If you are using MySQL there is the DATEDIFF function which calculate the days between two dates:

SELECT dtCreated
    , bActive
    , dtLastPaymentAttempt
    , dtLastUpdated
    , dtLastVisit
    , DATEDIFF(dtLastUpdated, dtCreated) as Difference
FROM Customers
WHERE (bActive = 'true') 
    AND (dtLastUpdated > CONVERT(DATETIME, '2012-01-0100:00:00', 102))

In my case, another developer had removed some of the tables from the underlying database. When I realised this, and removed these tables from the entity, the problem was solved. Wasn't as obvious as it sounds.

The actual thing over here is to use wrap_content instead of match_parent. If you will use match_parent the layout will be filled with the stars even if it is more than the numStars variable.

You can do it like this, and no need to dedicate variable:

Toolbar toolbar = findViewById(R.id.toolbar);
Menu menu = toolbar.getMenu();
MenuItem menuItem = menu.findItem(R.id.some_action);
menuItem.setTitle("New title");

Or a little simplified:

MenuItem menuItem = ((Toolbar)findViewById(R.id.toolbar)).getMenu().findItem(R.id.some_action);
menuItem.setTitle("New title");

It works only - after the menu created.

This should do what you are looking for:

<html>
    <head>
        <style type="text/css">
            #header {
                text-align: center;
            }
            #wrapper {
                margin:0 auto;
                width:600px;
            }
            #submain {
                margin:0 auto;
                width:600px;
            }
            #sub-left {
                float:left;
                width:300px;
            }
            #sub-right {
                float:right;
                width:240px;
                text-align: right;
            }
        </style>

    </head>
    <body>
        <div id="wrapper">
            <div id="header"><h1>Head</h1></div>
            <div id="sub-main">
                <div id="sub-left">
                    Right
                </div>
                <div id="sub-right">
                    Left
                </div>
            </div>
        </div>
    </body>
</html>

And you can control the entire document with the wrapper class, or just the two columns with the sub-main class.

You can use JQuery to ensure that all elements of the documents are ready before it starts the client side scripting

$(document).ready(
    function()
    {
        document.getElementById(elmId).innerHTML = value;
    }
);

You're doing only one mistake.

use replaceAll() function over there.

e.g.

String str = "Hi";
String str1 = "hello";
str.replaceAll( str, str1 );

following command will download pyyaml, which also includes yaml

pip install pyYaml

Just specifying HTTPS in the URI should do the trick.

httpClient.BaseAddress = new Uri("https://foobar.com/");

If the request works with HTTP but fails with HTTPS then this is most certainly a certificate issue. Make sure the caller trusts the certificate issuer and that the certificate is not expired. A quick and easy way to check that is to try making the query in a browser.

You also may want to check on the server (if it's yours and / or if you can) that it is set to serve HTTPS requests properly.

Note :

From API Level 26, you also don't need to specifically cast the result of findViewById as it uses inference for its return type.

So now you can simply do,

public View onCreateView(LayoutInflater inflater, 
                         ViewGroup container, 
                         Bundle savedInstanceState) {
     View view = inflater.inflate(R.layout.testclassfragment, container, false);
     ImageView imageView =  view.findViewById(R.id.my_image); //without casting the return type
     return view;
}

In bash foo is the name of the variable, and $ is an operator which means 'get the value of'.

In perl $foo is the name of the variable.

A variation on SquareRootOf2's answer, but this should be placed before the first use of the $output variable:

$keys = array('key1', 'key2', 'etc');
$output = array_fill_keys($keys, '');

Use the substring method of the String class :

String removeCurrency=amount.getText().toString().substring(3);

Imagine you are designing a programming language. You decide that Strings are enclosed in quotes ("Apple"). Then you hit your first snag: how to represent quotation marks since you've already used them ? Just out of convention you decide to use \" to represent quotation marks. Then you have a second problem: how to represent \ ? Again, out of convention you decide to use \\ instead. Thankfully, the process ends there and this is sufficient. You can also use what is called an escape sequence to represent other characters such as the carriage return (\n).

@sudo_O has the right answer.

This can't work:

someprocess < file > file

The shell performs the redirections before handing control over to someprocess (redirections). The > redirection will truncate the file to zero size (redirecting output). Therefore, by the time someprocess gets launched and wants to read from the file, there is no data for it to read.

pyplot is a sub-module of matplotlib which doesn't get imported with a simple import matplotlib.

>>> import matplotlib
>>> print matplotlib.pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'
>>> import matplotlib.pyplot
>>> 

It seems customary to do: import matplotlib.pyplot as plt at which time you can use the various functions and classes it contains:

p = plt.plot(...)

here is a full (gmail) and simple solution... just use normal ; delimiter.. best for passing in as params.

$to = "[email protected];[email protected]"
$user = "[email protected]"    
$pass = ConvertTo-SecureString -String "pass" -AsPlainText -Force

$cred = New-Object System.Management.Automation.PSCredential $user, $pass
$mailParam = @{
    To = $to.Split(';')
    From = "IT Alerts <[email protected]>"
    Subject = "test"
    Body = "test"
    SmtpServer = "smtp.gmail.com"
    Port = 587
    Credential = $cred
}

Send-MailMessage @mailParam -UseSsl

You have the :nth-child() pseudo-class:

table tr:nth-child(odd) td{
    ...
}
table tr:nth-child(even) td{
    ...
}

In the early days of :nth-child() its browser support was kind of poor. That's why setting class="odd" became such a common technique. In late 2013 I'm glad to say that IE6 and IE7 are finally dead (or sick enough to stop caring) but IE8 is still around — thankfully, it's the only exception.

If you use jQuery you can write:

$( _checkbox ).click( function( e ){ /*process event here*/ } )

use the net use command:

net use Z: \\10.0.1.1\DRIVENAME

Edit 1: Also, I believe the password should be simply appended:

net use Z: \\10.0.1.1\DRIVENAME PASSWORD

You can find out more about this command and its arguments via:

net use ?

Edit 2: As Tomalak mentioned in comments, you can later un-map it via

net use Z: \delete

You can try like this

  <select name="hall" id="hall">
      <option>1</option>
      <option>2</option>
      <option selected="selected">3</option>
      <option>4</option>
      <option>5</option>
    </select>

I found the reason why the connection was not working, it was because the connection was trying to connect to port 8888, when it needed to connect to port 8889.

$conn = new PDO("mysql:host=$servername;port=8889;dbname=AppDatabase", $username, $password); 

This fixed the problem, although changing the server name to localhost still gives the error.

Connection failed: SQLSTATE[HY000] [2002] No such file or directory

But it connects successfully when the IP address is entered for the server name.

Java does not provide a construct that will assign of multiple values to an existing array's elements. The initializer syntaxes can ONLY be used when creation a new array object. This can be at the point of declaration, or later on. But either way, the initializer is initializing a new array object, not updating an existing one.

Wasted several hours only to realize that viewport meta was missing from my code. Adding here just in case some one else misses it out.

Use the std::getline() from <string>.

 istream & getline(istream & is,std::string& str)

So, for your case it would be:

std::getline(read,x);

In my case eclipse.ini entry for --launcher.library was :

--launcher.library C:\Users\UserName\.p2\pool\plugins\org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.551.v20171108-1834

and on my machine 'C:\Users\UserName\.p2\' folder was missing hence installed the eclipse again which created the .p2 folder structure at required location and now I am able to login successfully.

All the answer explain the problem really good.

However, I would like to add another information.

I faced the same problem at the moment I wanted the output of a function to be a vector.

In this situation, the common solution is to declare the output as an argument of the function itself. This way, the alloc of the variable and the physical space necessary to store the information are managed outside the function. Pseudocode to explain the classical solution is:

void function(int input, int* output){
    //...
    output[0] = something;
    output[1] = somethig_else;
    //...
    return;
}

In this case, the example code within the question should be changed in:

void foo(int x, char* a){
     if(x < 0){
        char b = "blah";
        //...
        strcpy(a, b);
        //..
        return;
      }
    //..
}

You may also want to make sure that your code localizes correctly, or make sure the users are used to the "international" notation. For example, "1,112" actually means different numbers across different countries. In Germany it means the number a little over one, instead of one thousand and something.

Corresponding Wikipedia article is at http://en.wikipedia.org/wiki/Decimal_mark. It seems to be poorly written at this time though. For example as a Chinese I'm not sure where does these description about thousand separator in China come from.

There is a c++ class called _bstr_t. It has useful methods and a collection of overloaded operators.

For example, you can easily assign from a const wchar_t * or a const char * just doing _bstr_t bstr = L"My string"; Then you can convert it back doing const wchar_t * s = bstr.operator const wchar_t *();. You can even convert it back to a regular char const char * c = bstr.operator char *(); You can then just use the const wchar_t * or the const char * to initialize a new std::wstring oe std::string.

In eclipse:

You may have to drag the DDMS window down. 'Location Controls' is located under 'Telephony Actions' and may be hidden by a normally sized console view ( the bar with console, LogCat etc may be covering it!)

Automated interactive rebase edit followed by commit revert ready for a do-over

I found myself fixing a past commit frequently enough that I wrote a script for it.

Here's the workflow:

1. git commit-edit <commit-hash>
   

   This will drop you at the commit you want to edit.

2. Fix and stage the commit as you wish it had been in the first place.

   (You may want to use git stash save to keep any files you're not committing)

3. Redo the commit with --amend, eg:

   git commit --amend
   

4. Complete the rebase:

   git rebase --continue
   

For the above to work, put the below script into an executable file called git-commit-edit somewhere in your $PATH:

#!/bin/bash

set -euo pipefail

script_name=${0##*/}

warn () { printf '%s: %s\n' "$script_name" "$*" >&2; }
die () { warn "$@"; exit 1; }

[[ $# -ge 2 ]] && die "Expected single commit to edit. Defaults to HEAD~"

# Default to editing the parent of the most recent commit
# The most recent commit can be edited with `git commit --amend`
commit=$(git rev-parse --short "${1:-HEAD~}")
message=$(git log -1 --format='%h %s' "$commit")

if [[ $OSTYPE =~ ^darwin ]]; then
  sed_inplace=(sed -Ei "")
else
  sed_inplace=(sed -Ei)
fi

export GIT_SEQUENCE_EDITOR="${sed_inplace[*]} "' "s/^pick ('"$commit"' .*)/edit \\1/"'
git rebase --quiet --interactive --autostash --autosquash "$commit"~
git reset --quiet @~ "$(git rev-parse --show-toplevel)"  # Reset the cache of the toplevel directory to the previous commit
git commit --quiet --amend --no-edit --allow-empty  #  Commit an empty commit so that that cache diffs are un-reversed

echo
echo "Editing commit: $message" >&2

Version 1:

// Update data of question values with $data from formulay
$Q1 = Question::find($id);
$Q1->fill($data);
$Q1->push();

Version 2:

$Q1 = Question::find($id);
$Q1->field = 'YOUR TEXT OR VALUE';
$Q1->save();

In case of answered question you can use them:

$page = Page::find($id);
$page2update = $page->where('image', $path);
$page2update->image = 'IMGVALUE';
$page2update->save();

You can call a function on click event of button.

<input type="button" class="btn btn-info" value="Input Button" onclick=" relocate_home()">

<script>
function relocate_home()
{
     location.href = "www.yoursite.com";
} 
</script>

OR Use this Code

<a href="#link" class="btn btn-info" role="button">Link Button</a>

I wanted to clarify some more use between the ; and the /

In SQLPLUS:

1. ; means "terminate the current statement, execute it and store it to the SQLPLUS buffer"
2. <newline> after a D.M.L. (SELECT, UPDATE, INSERT,...) statement or some types of D.D.L (Creating Tables and Views) statements (that contain no ;), it means, store the statement to the buffer but do not run it.
3. / after entering a statement into the buffer (with a blank <newline>) means "run the D.M.L. or D.D.L. or PL/SQL in the buffer.
4. RUN or R is a sqlsplus command to show/output the SQL in the buffer and run it. It will not terminate a SQL Statement.
5. / during the entering of a D.M.L. or D.D.L. or PL/SQL means "terminate the current statement, execute it and store it to the SQLPLUS buffer"

NOTE: Because ; are used for PL/SQL to end a statement ; cannot be used by SQLPLUS to mean "terminate the current statement, execute it and store it to the SQLPLUS buffer" because we want the whole PL/SQL block to be completely in the buffer, then execute it. PL/SQL blocks must end with:

END;

Scipy.org recommends that you use arrays:

*'array' or 'matrix'? Which should I use? - Short answer

Use arrays.

• They are the standard vector/matrix/tensor type of numpy. Many numpy function return arrays, not matrices.

• There is a clear distinction between element-wise operations and linear algebra operations.

• You can have standard vectors or row/column vectors if you like.

The only disadvantage of using the array type is that you will have to use dot instead of * to multiply (reduce) two tensors (scalar product, matrix vector multiplication etc.).

Personally, I don't think there is any real world use for StringBuffer. When would I ever want to communicate between multiple threads by manipulating a character sequence? That doesn't sound useful at all, but maybe I have yet to see the light :)

Try mpstat from the sysstat package

> sudo apt-get install sysstat
Linux 3.0.0-13-generic (ws025)  02/10/2012  _x86_64_    (2 CPU)  

03:33:26 PM  CPU    %usr   %nice    %sys %iowait    %irq   %soft  %steal  %guest   %idle

Then some cutor grepto parse the info you need:

mpstat | grep -A 5 "%idle" | tail -n 1 | awk -F " " '{print 100 -  $ 12}'a

Step by step that I use:

 - sudo apt-get install python-dev
 - sudo apt-get install postgresql-server-dev-9.1
 - sudo apt-get install python-psycopg2 - Or sudo pip install psycopg2

You may want to install a graphic tool to manage your databases, for that you can do:

sudo apt-get install postgresql pgadmin3 

After, you must change Postgre user password, then do:

 - sudo su
 - su postgres -c psql postgres
 - ALTER USER postgres WITH PASSWORD 'YourPassWordHere';
 - \q

On your settings.py file you do:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'dbname',
        'USER': 'postgres',
        'PASSWORD': 'postgres',
        'HOST': '',
        'PORT': '',
    }
}

Extra:

If you want to create the db using the command line you can just do:

- sudo su
- su postgres -c psql postgres
- CREATE DATABASE dbname;
- CREATE USER djangouser WITH ENCRYPTED PASSWORD 'myPasswordHere';
- GRANT ALL PRIVILEGES ON DATABASE dbname TO djangouser;

On your settings.py file you do:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'dbname',
        'USER': 'djangouser',
        'PASSWORD': 'myPasswordHere',
        'HOST': '',
        'PORT': '',
    }
}

You can place your tables in a div and add style to your table "float: left"

<div>
  <table style="float: left">
    <tr>
      <td>..</td>
    </tr>
  </table>
  <table style="float: left">
    <tr>
      <td>..</td>
    </tr>
  </table>
</div>

or simply use css:

div>table {
  float: left
}

I've had this problem before, you can go to "advanced" tab of "choose a data source" page and click on "suggested types" button, and set the "number of rows" as much as you want. after that, the type and text qualified are set to the true values.

i applied the above solution and can convert my data to SQL.

If you have the char array null terminated, you can assign the char array to the string:

char[] chArray = "some characters";
String String(chArray);

As for your loop code, it looks right, but I will try on my controller to see if I get the same problem.

First of all, do a backup of your needed databases with mysqldump

Note: If you want to restore later, just backup your relevant databases, and not the WHOLE, because the whole database might actually be the reason you need to purge and reinstall).

In total, do this:

sudo service mysql stop  #or mysqld
sudo killall -9 mysql
sudo killall -9 mysqld
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
sudo deluser -f mysql
sudo rm -rf /var/lib/mysql
sudo apt-get purge mysql-server-core-5.7
sudo apt-get purge mysql-client-core-5.7
sudo rm -rf /var/log/mysql
sudo rm -rf /etc/mysql

All above commands in single line (just copy and paste):

sudo service mysql stop && sudo killall -9 mysql && sudo killall -9 mysqld && sudo apt-get remove --purge mysql-server mysql-client mysql-common && sudo apt-get autoremove && sudo apt-get autoclean && sudo deluser mysql && sudo rm -rf /var/lib/mysql && sudo apt-get purge mysql-server-core-5.7 && sudo apt-get purge mysql-client-core-5.7 && sudo rm -rf /var/log/mysql && sudo rm -rf /etc/mysql

You can run PHP as with any web-server, using the SPHP module for node.
It's compatible but not dependent on express.
It also supports websockets requests on the HTTP port.
Its biased for speed under small load, rather then saving resources.

To install in node:

npm install sphp

in you app:

var express = require('express');
var sphp = require('sphp');

var app = express();
var server = app.listen(8080);

app.use(sphp.express('public/'));
app.use(express.static('public/'));

For more information, look at https://github.com/paragi/sphp

I'm slightly biased too because I'm the author :)

<div class="cell">hello mars! kind regards, world</div>

check if file exist in side the document/catchimage path :

NSString *stringPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];
NSString *tempName = [NSString stringWithFormat:@"%@/catchimage/%@.png",stringPath,@"file name"];
NSLog(@"%@",temName);
if([[NSFileManager defaultManager] fileExistsAtPath:temName]){
    // ur code here
} else {
    // ur code here** 
}

You can do it in this way

// xyz.h
#ifndef _XYZ_
#define _XYZ_

template <typename XYZTYPE>
class XYZ {
  //Class members declaration
};

#include "xyz.cpp"
#endif

//xyz.cpp
#ifdef _XYZ_
//Class definition goes here

#endif

The HOME button cannot be intercepted by applications. This is a by-design behavior in Android. The reason is to prevent malicious apps from gaining control over your phone (If the user cannot press back or home, he might never be able to exit the app). The Home button is considered the user's "safe zone" and will always launch the user's configured home app.

The only exception to the above is any app configured as home replacement. Which means it has the following declared in its AndroidManifest.xml for the relevant activity:

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

When pressing the home button, the current home app's activity's onNewIntent will be called.

}

def emit_li(stuff, strong=False):

    print(emission % stuff)

def iterate(a_list):
    print('<ul>')
    map(unravel, a_list)
    print('</ul>')

def delve(a_dict):

        unravel(value)
    print('</ul>')

def unravel(structure):
    h = handlers[type(structure)]
    return h(structure)

unravel(data)

where data is a python list (parsed from a JSON text string):

JSFiddle: https://jsfiddle.net/derrh5tr/

If you have a slow page or network connection, chances are that none of the above will work. I have tried them all and the only thing that worked for me is to wait for the last visible element on that page. Take for example the Bing webpage. They have placed a CAMERA icon (search by image button) next to the main search button that is visible only after the complete page has loaded. If everyone did that, then all we have to do is use an explicit wait like in the examples above.

An alternative way:

Here is a working example and here is the code, you should also use prop.

$('input[type="checkbox"]').mouseenter(function() { 
    if ($(this).is(':checked')) {
        //$(this).prop('checked',false);
        alert("is checked");
    } else {
         //$(this).prop('checked',true);
        alert("not checked");
    }
});?

I commented out the way to toggle the checked attribute.

            res.on('data', function(chunk) {
                body.push(chunk);
            });
            res.on('end', function() {
                try {
                    body = JSON.parse(Buffer.concat(body).toString());
                } catch(e) {
                    reject(e);
                }
                resolve(body);
            });
        });
        req.on('error', (e) => {
          reject(e.message);
        });
        // send the request
       req.end();
    });
}

While you can do OO in C (e.g. by adding a theType *this first parameter to methods, and manually handling something like vtables for polymorphism) this is never particularly satisfactory as a design, and will look ugly (even with some pre-processor hacks).

I would suggest at least looking at a re-design to compare how this would work out.

Overall a lot depends on the answer to the key question: if you have working C++ code, why do you want C instead?

I think this the better way with knowing the logic itself

var arrayOfInts = [2, 2, 4, 4]
var mainArray = [Int]()

for value in arrayOfInts {

if mainArray.contains(value) != true  {
    
    mainArray.append(value)
    print("mainArray:\(mainArray)")
}}

Even though this question is very old and I stumbled upon it for my own issues with JPA 2.0 and Oracle sequences.

Want to share my research on some of the things -

Relationship between @SequenceGenerator(allocationSize) of GenerationType.SEQUENCE and INCREMENT BY in database sequence definition

Make sure @SequenceGenerator(allocationSize) is set to same value as INCREMENT BY in Database sequence definition to avoid problems (the same applies to the initial value).

For example, if we define the sequence in database with a INCREMENT BY value of 20, set the allocationsize in SequenceGenerator also to 20. In this case the JPA will not make a call to database until it reaches the next 20 mark while it increments each value by 1 internally. This saves database calls to get the next sequence number each time. The side effect of this is - Whenever the application is redeployed or the server is restarted in between, it'll call database to get the next batch and you'll see jumps in the sequence values. Also we need to make sure the database definition and the application setting to be in-sync which may not be possible all the time as both of them are managed by different groups and you can quickly lose control of. If database value is less than the allocationsize, you'll see PrimaryKey constraint errors due to duplicate values of Id. If the database value is higher than the allocationsize, you'll see jumps in the values of Id.

If the database sequence INCREMENT BY is set to 1 (which is what DBAs generally do), set the allocationSize as also 1 so that they are in-sync but the JPA calls database to get next sequence number each time.

If you don't want the call to database each time, use GenerationType.IDENTITY strategy and have the @Id value set by database trigger. With GenerationType.IDENTITY as soon as we call em.persist the object is saved to DB and a value to id is assigned to the returned object so we don't have to do a em.merge or em.flush. (This may be JPA provider specific..Not sure)

Another important thing -

JPA 2.0 automatically runs ALTER SEQUENCE command to sync the allocationSize and INCREMENT BY in database sequence. As mostly we use a different Schema name(Application user name) rather than the actual Schema where the sequence exists and the application user name will not have ALTER SEQUENCE privileges, you might see the below warning in the logs -

000004c1 Runtime W CWWJP9991W: openjpa.Runtime: Warn: Unable to cache sequence values for sequence "RECORD_ID_SEQ". Your application does not have permission to run an ALTER SEQUENCE command. Ensure that it has the appropriate permission to run an ALTER SEQUENCE command.

As the JPA could not alter the sequence, JPA calls database everytime to get next sequence number irrespective of the value of @SequenceGenerator.allocationSize. This might be a unwanted consequence which we need to be aware of.

To let JPA not to run this command, set this value - in persistence.xml. This ensures that JPA will not try to run ALTER SEQUENCE command. It writes a different warning though -

00000094 Runtime W CWWJP9991W: openjpa.Runtime: Warn: The property "openjpa.jdbc.DBDictionary=disableAlterSeqenceIncrementBy" is set to true. This means that the 'ALTER SEQUENCE...INCREMENT BY' SQL statement will not be executed for sequence "RECORD_ID_SEQ". OpenJPA executes this command to ensure that the sequence's INCREMENT BY value defined in the database matches the allocationSize which is defined in the entity's sequence. With this SQL statement disabled, it is the responsibility of the user to ensure that the entity's sequence definition matches the sequence defined in the database.

As noted in the warning, important here is we need to make sure @SequenceGenerator.allocationSize and INCREMENT BY in database sequence definition are in sync including the default value of @SequenceGenerator(allocationSize) which is 50. Otherwise it'll cause errors.

Give the Exec Maven plugin a try

Your Last Edittext .setOnEditorActionListener call this method automatic hit api

Description

You can do this using jQuery's .scrollTop() and .offset() method

Check out my sample and this jsFiddle Demonstration

$(function() {
    $(document).scrollTop( $("#header").offset().top );  
});

In Linux, you can start a process in a new independent thread by appending an ampersand at the end of the command

mycommand -someparam somevalue &

In Windows, you can use the "start" DOS command

start mycommand -someparam somevalue

It is purely a string:

startInfo.Arguments = "-sk server -sky exchange -pe -n CN=localhost -ir LocalMachine -is Root -ic MyCA.cer -sr LocalMachine -ss My MyAdHocTestCert.cer"

Of course, when arguments contain whitespaces you'll have to escape them using \" \", like:

"... -ss \"My MyAdHocTestCert.cer\""

See MSDN for this.

This is working for me:

$user_info = DB::table('usermetas')
                 ->select('browser', DB::raw('count(*) as total'))
                 ->groupBy('browser')
                 ->get();

You can do like..

DataRow[] dr = dtbl.Select("SUM(Amount)");
txtTotalAmount.Text = Convert.ToString(dr[0]);

A couple of things:

• You need to set the video bitrate. I have never used minrate and maxrate so I don't know how exactly they work, but by setting the bitrate using the -b switch, I am able to get high quality video. You need to come up with a bitrate that offers a good tradeoff between compression and video quality. You may have to experiment with this because it all depends on the frame size, frame rate and the amount of motion in the content of your video. Keep in mind that DVD tends to be around 4-5 Mbit/s on average for 720x480, so I usually start from there and decide whether I need more or less and then just experiment. For example, you could add -b 5000k to the command line to get more or less DVD video bitrate.

• You need to specify a video codec. If you don't, ffmpeg will default to MPEG-1 which is quite old and does not provide near the amount of compression as MPEG-4 or H.264. If your ffmpeg version is built with libx264 support, you can specify -vcodec libx264 as part of the command line. Otherwise -vcodec mpeg4 will also do a better job than MPEG-1, but not as well as x264.

• There are a lot of other advanced options that will help you squeeze out the best quality at the lowest bitrates. Take a look here for some examples.

EDIT: This only works on API 8+ as noted by some of the comments.

This is a late answer, but you can add an onShowListener to the AlertDialog where you can then override the onClickListener of the button.

final AlertDialog dialog = new AlertDialog.Builder(context)
        .setView(v)
        .setTitle(R.string.my_title)
        .setPositiveButton(android.R.string.ok, null) //Set to null. We override the onclick
        .setNegativeButton(android.R.string.cancel, null)
        .create();

dialog.setOnShowListener(new DialogInterface.OnShowListener() {

    @Override
    public void onShow(DialogInterface dialogInterface) {

        Button button = ((AlertDialog) dialog).getButton(AlertDialog.BUTTON_POSITIVE);
        button.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                // TODO Do something

                //Dismiss once everything is OK.
                dialog.dismiss();
            }
        });
    }
});
dialog.show();

Short Answer:

I did it. I wrote a function for dynamic usage for all the little people out there...

Working example which displays on the page

Working example logging to the console

Long Answer:

...Still did it.

It took me awhile to do it, since a psuedo element is not really on the page. While some of the answers above work in SOME scenarios, they ALL fail to be both dynamic and work in a scenario in which an element is both unexpected in size and position(such as absolute positioned elements overlaying a portion of the parent element). Mine does not.

Usage:

//some element selector and a click event...plain js works here too
$("div").click(function() {
    //returns an object {before: true/false, after: true/false}
    psuedoClick(this);

    //returns true/false
    psuedoClick(this).before;

    //returns true/false
    psuedoClick(this).after;

});

How it works:

It grabs the height, width, top, and left positions(based on the position away from the edge of the window) of the parent element and grabs the height, width, top, and left positions(based on the edge of the parent container) and compares those values to determine where the psuedo element is on the screen.

It then compares where the mouse is. As long as the mouse is in the newly created variable range then it returns true.

Note:

It is wise to make the parent element RELATIVE positioned. If you have an absolute positioned psuedo element, this function will only work if it is positioned based on the parent's dimensions(so the parent has to be relative...maybe sticky or fixed would work too....I dont know).

Code:

function psuedoClick(parentElem) {

    var beforeClicked,
      afterClicked;

  var parentLeft = parseInt(parentElem.getBoundingClientRect().left, 10),
      parentTop = parseInt(parentElem.getBoundingClientRect().top, 10);

  var parentWidth = parseInt(window.getComputedStyle(parentElem).width, 10),
      parentHeight = parseInt(window.getComputedStyle(parentElem).height, 10);

  var before = window.getComputedStyle(parentElem, ':before');

  var beforeStart = parentLeft + (parseInt(before.getPropertyValue("left"), 10)),
      beforeEnd = beforeStart + parseInt(before.width, 10);

  var beforeYStart = parentTop + (parseInt(before.getPropertyValue("top"), 10)),
      beforeYEnd = beforeYStart + parseInt(before.height, 10);

  var after = window.getComputedStyle(parentElem, ':after');

  var afterStart = parentLeft + (parseInt(after.getPropertyValue("left"), 10)),
      afterEnd = afterStart + parseInt(after.width, 10);

  var afterYStart = parentTop + (parseInt(after.getPropertyValue("top"), 10)),
      afterYEnd = afterYStart + parseInt(after.height, 10);

  var mouseX = event.clientX,
      mouseY = event.clientY;

  beforeClicked = (mouseX >= beforeStart && mouseX <= beforeEnd && mouseY >= beforeYStart && mouseY <= beforeYEnd ? true : false);

  afterClicked = (mouseX >= afterStart && mouseX <= afterEnd && mouseY >= afterYStart && mouseY <= afterYEnd ? true : false);

  return {
    "before" : beforeClicked,
    "after"  : afterClicked

  };      

}

Support:

I dont know....it looks like ie is dumb and likes to return auto as a computed value sometimes. IT SEEMS TO WORK WELL IN ALL BROWSERS IF DIMENSIONS ARE SET IN CSS. So...set your height and width on your psuedo elements and only move them with top and left. I recommend using it on things that you are okay with it not working on. Like an animation or something. Chrome works...as usual.

You need to manually download the apt deb package. Then run dpkg and it should install.

#multiplying each element in the list and adding it into an empty list
original = [1, 2, 3]
results = []
for num in original:
    results.append(num*2)# multiply each iterative number by 2 and add it to the empty list.

print(results)

Please note if you are downloading from the FTP to your local, you will need to use the following:

with open( filename, 'wb' ) as file :
        ftp.retrbinary('RETR %s' % filename, file.write)

Otherwise, the script will at your local file storage rather than the FTP.

I spent a few hours making the mistake myself.

Script below:

import ftplib

# Open the FTP connection
ftp = ftplib.FTP()
ftp.cwd('/where/files-are/located')


filenames = ftp.nlst()

for filename in filenames:

    with open( filename, 'wb' ) as file :
        ftp.retrbinary('RETR %s' % filename, file.write)

        file.close()

ftp.quit()

<div id"content">
<div id"contentLeft"></div>
<div id"contentRight"></div>
</div> 

#content {
clear: both;
width: 950px;
padding-bottom: 10px;
background:#fff;
overflow:hidden;
}
#contentLeft {
float: left;
display:inline;
width: 630px;
margin: 10px;
background:#fff;
}
#contentRight {
float: right;
width: 270px;
margin-top:25px;
margin-right:15px;
background:#d7e5f7;
} 

Obviously you will need to adjust the size of the columns to suit your site as well as colours etc but that should do it. You also need to make sure that your ContentLeft and ContentRight widths do not exceed the Contents width (including margins).

In Windows 7, the command is

fsutil hardlink create new-file existing-file

PowerShell finds it without the full path (c:\Windows\system32) or extension (.exe).

I have used graphviz ( https://www.graphviz.org/gallery ) together with LaTeX using dot command to generate graphs in PDF and includegraphics to include those.

If graphviz produces what you are aiming at, this might be the best way to integrate: dot2tex: https://ctan.org/pkg/dot2tex?lang=en

{{app.session}} refers to the Session object and not the $_SESSION array. I don't think the $_SESSION array is accessible unless you explicitly pass it to every Twig template or if you do an extension that makes it available.

Symfony2 is object-oriented, so you should use the Session object to set session attributes and not rely on the array. The Session object will abstract this stuff away from you so it is easier to, say, store the session in a database because storing the session variable is hidden from you.

So, set your attribute in the session and retrieve the value in your twig template by using the Session object.

// In a controller
$session = $this->get('session');
$session->set('filter', array(
    'accounts' => 'value',
));

// In Twig
{% set filter = app.session.get('filter') %}
{% set account-filter = filter['accounts'] %}

Hope this helps.

I would like to add a NULL check and IndexOutOfBoundsException on the accepted answer.

String output = input.substring(0, 1).toUpperCase() + input.substring(1);

Java Code:

  class Main {
      public static void main(String[] args) {
        System.out.println("Capitalize first letter ");
        System.out.println("Normal  check #1      : ["+ captializeFirstLetter("one thousand only")+"]");
        System.out.println("Normal  check #2      : ["+ captializeFirstLetter("two hundred")+"]");
        System.out.println("Normal  check #3      : ["+ captializeFirstLetter("twenty")+"]");
        System.out.println("Normal  check #4      : ["+ captializeFirstLetter("seven")+"]");

        System.out.println("Single letter check   : ["+captializeFirstLetter("a")+"]");
        System.out.println("IndexOutOfBound check : ["+ captializeFirstLetter("")+"]");
        System.out.println("Null Check            : ["+ captializeFirstLetter(null)+"]");
      }

      static String captializeFirstLetter(String input){
             if(input!=null && input.length() >0){
                input = input.substring(0, 1).toUpperCase() + input.substring(1);
            }
            return input;
        }
    }

Output:

Normal  check #1      : [One thousand only]
Normal  check #2      : [Two hundred]
Normal  check #3      : [Twenty]
Normal  check #4      : [Seven]
Single letter check   : [A]
IndexOutOfBound check : []
Null Check            : [null]

I had the same trouble, this is what worked for me.

You can click at the wampserver icon, then at the PHP error log. Check if it says this: Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_ldap.dll'

If yes, then you can reload your version of PHP, by clicking at the wampserver icon, then PHP, then version, and then you click at your version. Wait for everything to be online again, then try to access phpmyadmin.

Is there any way you could programatically apply a class to the object?

<object class="hasparams">

then do

object.hasparams

Replace @RequestMapping( "/item" ) with @GetMapping(value="/item", produces=MediaType.APPLICATION_JSON_VALUE).

Maybe it will help somebody.

Something like:

var rnd = new Random(DateTime.Now.Millisecond);
int ticks = rnd.Next(0, 3000);

I met this problem today, and fix it with bellowed steps.

1, Check the log file /var/log/mysqld.log

tail -f /var/log/mysqld.log

 2017-03-14T07:06:53.374603Z 0 [ERROR] /usr/sbin/mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 2 - No such file or directory)
 2017-03-14T07:06:53.374614Z 0 [ERROR] Can't start server: can't create PID file: No such file or directory

The log says that there isn't a file or directory /var/run/mysqld/mysqld.pid

2, Create the directory /var/run/mysqld

mkdir -p /var/run/mysqld/

3, Start the mysqld again service mysqld start, but still fail, check the log again /var/log/mysqld.log

2017-03-14T07:14:22.967667Z 0 [ERROR] /usr/sbin/mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 13 - Permission denied)
2017-03-14T07:14:22.967678Z 0 [ERROR] Can't start server: can't create PID file: Permission denied

It saids permission denied.

4, Grant the permission to mysql chown mysql.mysql /var/run/mysqld/

5, Restart the mysqld

# service mysqld restart
Restarting mysqld (via systemctl):                         [  OK  ]

You might want to start with scapy.

In case someone else stumbles upon this question and wants it here is the SASS mixin I use.

@mixin rotate($deg: 90){
    $sDeg: #{$deg}deg;

    -webkit-transform: rotate($sDeg);
    -moz-transform: rotate($sDeg);
    -ms-transform: rotate($sDeg);
    -o-transform: rotate($sDeg);
    transform: rotate($sDeg);
}

You can use an alert dialog

    AlertDialog.Builder b = new Builder(this);
    b.setTitle("Example");
    String[] types = {"By Zip", "By Category"};
    b.setItems(types, new OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {

            dialog.dismiss();
            switch(which){
            case 0:
                onZipRequested();
                break;
            case 1:
                onCategoryRequested();
                break;
            }
        }

    });

    b.show();

This will close the dialog when one of them is pressed like you are wanting. Hope this helps!

What you are doing is correct, the problem is somewhere else, e.g. the cookie is being set again somehow on refresh.

If you want to fetch + merge, run

git pull

if you want simply to fetch :

git fetch

As pointed out in other answers, the selected answer is wrong.

The answer to another question suggests that it may be skip-worktree that would be required.

git update-index --skip-worktree <file>

Had to restart the Eclipse after completing the installation of ARM EABI v7a system image.

Ok so this one works. Just in case anybody wants it, here's the version that works for me :)

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Base64;


public class HttpBasicAuth {

    public static void main(String[] args) {

        try {
            URL url = new URL ("http://ip:port/login");
            String encoding = Base64.getEncoder().encodeToString(("test1:test1").getBytes(?"UTF??-8"?));

            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);
            connection.setRequestProperty  ("Authorization", "Basic " + encoding);
            InputStream content = (InputStream)connection.getInputStream();
            BufferedReader in   = 
                new BufferedReader (new InputStreamReader (content));
            String line;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
        } catch(Exception e) {
            e.printStackTrace();
        }

    }

}

One more way to add view from Activity

ViewGroup rootLayout = findViewById(android.R.id.content);
rootLayout.addView(view);

The quick and easy way, which you definitely should not do (see below), is to read the whole file into a list of strings using readlines(). I write this in case the quick and easy solution is what you're looking for.

Just open the file using open(), then call the readlines() method. What you'll get is a list of all the strings in the file. Now, you can easily add strings before the last element (just add to the list one element before the last). Finally, you can write these back to the file using writelines().

An example might help:

my_file = open(filename, "r")
lines_of_file = my_file.readlines()
lines_of_file.insert(-1, "This line is added one before the last line")
my_file.writelines(lines_of_file)

The reason you shouldn't be doing this is because, unless you are doing something very quick n' dirty, you should be using an XML parser. This is a library that allows you to work with XML intelligently, using concepts like DOM, trees, and nodes. This is not only the proper way to work with XML, it is also the standard way, making your code both more portable, and easier for other programmers to understand.

Tim's answer mentioned checking out xml.dom.minidom for this purpose, which I think would be a great idea.

This is called heredoc format to provide a string into stdin. See https://en.wikipedia.org/wiki/Here_document#Unix_shells for more details.

From man bash:

Here Documents

This type of redirection instructs the shell to read input from the current source until a line containing only word (with no trailing blanks) is seen.

All of the lines read up to that point are then used as the standard input for a command.

The format of here-documents is:

          <<[-]word
                  here-document
          delimiter

No parameter expansion, command substitution, arithmetic expansion, or pathname expansion is performed on word. If any characters in word are quoted, the delimiter is the result of quote removal on word, and the lines in the here-document are not expanded. If word is unquoted, all lines of the here-document are subjected to parameter expansion, command substitution, and arithmetic expansion. In the latter case, the character sequence \<newline> is ignored, and \ must be used to quote the characters \, $, and `.

If the redirection operator is <<-, then all leading tab characters are stripped from input lines and the line containing delimiter. This allows here-documents within shell scripts to be indented in a natural fashion.

Another (probably not production-ready or recommended) method I just came up with is to concat the values to a string and count this string distinctively:

SELECT count(DISTINCT concat(id, name, address)) FROM mytable;

Date.now() returns a unix timestamp in milliseconds.

const now = Date.now(); // Unix timestamp in milliseconds_x000D_
console.log( now );

Prior to ECMAScript5 (I.E. Internet Explorer 8 and older) you needed to construct a Date object, from which there are several ways to get a unix timestamp in milliseconds:

console.log( +new Date );_x000D_
console.log( (new Date).getTime() );_x000D_
console.log( (new Date).valueOf() );

A nice handy overview table from the Bash Hackers Wiki:

where c in the third row is the first character of $IFS, the Input Field Separator, a shell variable.

If the arguments are to be stored in a script variable and the arguments are expected to contain spaces, I wholeheartedly recommend employing a "$*" trick with the input field separator set to tab IFS=$'\t'.

$('#selected ul').children().length;

or even better

 $('#selected li').length;

You can use the following:

Map<String, List<Student>> groupedStudents = new HashMap<String, List<Student>>();
for (Student student: studlist) {

For inversion from 0 to 1 and back you can use this library InvertImages, which provides support for IE 10. I also tested with IE 11 and it should work.

You can fire chnage event by these methods:

First

$('#selectid').change(function () {
    alert('This works');
}); 

Second

$(document).on('change', '#selectid', function() {
    alert('This Works');
});

Third

$(document.body).on('change','#selectid',function(){
    alert('This Works');
});

If this methods not working, check your jQuery working or not:

$(document).ready(function($) {
   alert('Jquery Working');
});

Without actually seeing your output file for confirmation, my guess is that you've got to get rid of the FIELDS ESCAPED BY value.

MySQL's FIELDS ESCAPED BY is probably behaving in two ways that you were not counting on: (1) it is only meant to be one character, so in your case it is probably equal to just one quotation mark; (2) it is used to precede each character that MySQL thinks needs escaping, including the FIELDS TERMINATED BY and LINES TERMINATED BY values. This makes sense to most of the computing world, but it isn't the way Excel does escaping.

I think your double REPLACE is working, and that you are successfully replacing literal newlines with spaces (two spaces in the case of Windows-style newlines). But if you have any commas in your data (literals, not field separators), these are being preceded by quotation marks, which Excel treats much differently than MySQL. If that's the case, then the erroneous newlines that are tripping up Excel are actually newlines that MySQL had intended as line terminators.

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"&&(
 echo admin...
)

GitLab by default marks master branch as protected (See part Protecting your code in https://about.gitlab.com/2014/11/26/keeping-your-code-protected/ why). If so in your case, then this can help:

Open your project > Settings > Repository and go to "Protected branches", find "master" branch into the list and click "Unprotect" and try again.

Here's an idea. Load all of your audio for a certain class of sounds into a single individual audio element where the src data is all of your samples in a contiguous audio file (probably want some silence between so you can catch and cut the samples with a timeout with less risk of bleeding to the next sample). Then, seek to the sample and play it when needed.

If you need more than one of these to play you can create an additional audio element with the same src so that it is cached. Now, you effectively have multiple "tracks". You can utilize groups of tracks with your favorite resource allocation scheme like Round Robin etc.

You could also specify other options like queuing sounds into a track to play when that resource becomes available or cutting a currently playing sample.

I searched for this question because I wanted a Python program to print assignment statements for some of the variables in the program. For example, it might print "foo = 3, bar = 21, baz = 432". The print function would need the variable names in string form. I could have provided my code with the strings "foo","bar", and "baz", but that felt like repeating myself. After reading the previous answers, I developed the solution below.

The globals() function behaves like a dict with variable names (in the form of strings) as keys. I wanted to retrieve from globals() the key corresponding to the value of each variable. The method globals().items() returns a list of tuples; in each tuple the first item is the variable name (as a string) and the second is the variable value. My variablename() function searches through that list to find the variable name(s) that corresponds to the value of the variable whose name I need in string form.

The function itertools.ifilter() does the search by testing each tuple in the globals().items() list with the function lambda x: var is globals()[x[0]]. In that function x is the tuple being tested; x[0] is the variable name (as a string) and x[1] is the value. The lambda function tests whether the value of the tested variable is the same as the value of the variable passed to variablename(). In fact, by using the is operator, the lambda function tests whether the name of the tested variable is bound to the exact same object as the variable passed to variablename(). If so, the tuple passes the test and is returned by ifilter().

The itertools.ifilter() function actually returns an iterator which doesn't return any results until it is called properly. To get it called properly, I put it inside a list comprehension [tpl[0] for tpl ... globals().items())]. The list comprehension saves only the variable name tpl[0], ignoring the variable value. The list that is created contains one or more names (as strings) that are bound to the value of the variable passed to variablename().

In the uses of variablename() shown below, the desired string is returned as an element in a list. In many cases, it will be the only item in the list. If another variable name is assigned the same value, however, the list will be longer.

>>> def variablename(var):
...     import itertools
...     return [tpl[0] for tpl in 
...     itertools.ifilter(lambda x: var is x[1], globals().items())]
... 
>>> var = {}
>>> variablename(var)
['var']
>>> something_else = 3
>>> variablename(something_else)
['something_else']
>>> yet_another = 3
>>> variablename(something_else)
['yet_another', 'something_else']

To answer your extra question:

You can set which rows should be repeated on every page using:

$objPHPExcel->getActiveSheet()->getPageSetup()->setRowsToRepeatAtTopByStartAndEnd(1, 5);

Now, row 1, 2, 3, 4 and 5 will be repeated.

add CSS or class to the input element which works in select and text tags like

style="pointer-events: none;background-color:#E9ECEF"

Here is short example of how serialization works. I was also learning about the same and I found two links useful. What Serialization is and how it can be done in .NET.

A sample program explaining serialization

If you don't understand the above program a much simple program with explanation is given here.

This issue can also occur when upgrade from XCODE 11.x to 12.0. After installation of new version of XCODE, restart system to overcome this issue.

The code works for me. (after adding missing except clause / import statements)

Did you put \ in the original code?

urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' \
              + stock + '/chartdata;type=quote;range=5d/csv'

If you omit it, it could be a cause of the exception:

>>> stock = 'GOOG'
>>> urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/'
>>> + stock + '/chartdata;type=quote;range=5d/csv'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary +: 'str'

BTW, string(e) should be str(e).

After spending a lot of time trying to resolve this issue, finally found a solution that works. The solution makes use of Spring's ResourceUtils. Should work for json files as well.

Thanks for the well written page by Lokesh Gupta : Blog

package utils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.util.ResourceUtils;

import java.io.FileInputStream;

To answer a few concerns on the comments :

Pretty sure I had this running on Amazon EC2 using java -jar target/image-service-slave-1.0-SNAPSHOT.jar

Look at my github repo : https://github.com/johnsanthosh/image-service to figure out the right way to run this from a JAR.

Actually, although I blogged (see Luke's answer), I think this is better than my IDisposable wrapper. Typical code:

Service<IOrderService>.Use(orderService=>
{
  orderService.PlaceOrder(request);
}); 

(edit per comments)

Since Use returns void, the easiest way to handle return values is via a captured variable:

int newOrderId = 0; // need a value for definite assignment
Service<IOrderService>.Use(orderService=>
  {
    newOrderId = orderService.PlaceOrder(request);
  });
Console.WriteLine(newOrderId); // should be updated

Simply you can do this:

    public void CheckNull(int? item)
    {
        if (item != null)
        {
            //Do Something
        }

    }

For laravel 8:

Model::orderBy('id', 'desc')->withTrashed()->take(1)->first()->id

The resulting sql query:

Model::orderBy('id', 'desc')->withTrashed()->take(1)->toSql()

select * from "timetables" order by "id" desc limit 1

There is not a way to directly get the version out, but there are two work-arounds that could be done.

1. The version could be stored in a resource string, and placed into the manifest by:

   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.somepackage"
        android:versionName="@string/version" android:versionCode="20">
   

2. One could create a custom view, and place it into the XML. The view would use this to assign the name:

   context.getPackageManager().getPackageInfo(context.getPackageName(), 0).versionName;
   

Either of these solutions would allow for placing the version name in XML. Unfortunately there isn't a nice simple solution, like android.R.string.version or something like that.

round does take negative ndigits parameter!

>>> round(46,-1)
50

may solve your case.

I had a ton of trouble with this and then found a great solution:

Create a file in a text editor called whoami.php with the below code as it's content, save the file and upload it to public_html (or whatever you root of your webserver directory is named). It should output a useful string that you can use to track down the user the webserver is running as, my output was "php is running as user: nt authority\iusr" which allowed me to track down the permissions I needed to modify to the user "IUSR".

<?php
  // outputs the username that owns the running php/httpd process
  // (on a system with the "whoami" executable in the path)
  echo 'php is running as user: ' . exec('whoami');
?>

This works for both git log and gitk - the 2 most common ways of viewing history.
You don't need to use the whole name:

git log --author="Jon"

will match a commit made by "Jonathan Smith"

git log --author=Jon

and

git log --author=Smith

would also work. The quotes are optional if you don't need any spaces.

Add --all if you intend to search all branches and not just the current commit's ancestors in your repo.

You can also easily match on multiple authors as regex is the underlying mechanism for this filter. So to list commits by Jonathan or Adam, you can do this:

git log --author="\(Adam\)\|\(Jon\)"

In order to exclude commits by a particular author or set of authors using regular expressions as noted in this question, you can use a negative lookahead in combination with the --perl-regexp switch:

git log --author='^(?!Adam|Jon).*$' --perl-regexp

Alternatively, you can exclude commits authored by Adam by using bash and piping:

git log --format='%H %an' | 
  grep -v Adam | 
  cut -d ' ' -f1 | 
  xargs -n1 git log -1

If you want to exclude commits commited (but not necessarily authored) by Adam, replace %an with %cn. More details about this are in my blog post here: http://dymitruk.com/blog/2012/07/18/filtering-by-author-name/

For that you can use the Application object.

Startup path, just the folder, use Application.StartupPath()

Dim appPath As String = Application.StartupPath()

Full .exe path, including the program.exe name on the end:, use Application.ExecutablePath()

Dim exePath As String = Application.ExecutablePath()

It is probably worth adding that an insert iterator of any kind (std::back_insert_iterator, std::front_insert_iterator, std::insert_iterator) is guaranteed to remain valid as long as all insertions are performed through this iterator and no other independent iterator-invalidating event occurs.

For example, when you are performing a series of insertion operations into a std::vector by using std::insert_iterator it is quite possible that these insertions will trigger vector reallocation, which will invalidate all iterators that "point" into that vector. However, the insert iterator in question is guaranteed to remain valid, i.e. you can safely continue the sequence of insertions. There's no need to worry about triggering vector reallocation at all.

This, again, applies only to insertions performed through the insert iterator itself. If iterator-invalidating event is triggered by some independent action on the container, then the insert iterator becomes invalidated as well in accordance with the general rules.

For example, this code

std::vector<int> v(10);
std::vector<int>::iterator it = v.begin() + 5;
std::insert_iterator<std::vector<int> > it_ins(v, it);

for (unsigned n = 20; n > 0; --n)
  *it_ins++ = rand();

is guaranteed to perform a valid sequence of insertions into the vector, even if the vector "decides" to reallocate somewhere in the middle of this process. Iterator it will obviously become invalid, but it_ins will continue to remain valid.

In my case changing firebase library version from 2.6.0 to 2.4.2 fixed the issue

Webpack >2.0

See wtk's answer.

Webpack 1.0

A more straightforward way to do this would be to use resolve.root.

http://webpack.github.io/docs/configuration.html#resolve-root

resolve.root

The directory (absolute path) that contains your modules. May also be an array of directories. This setting should be used to add individual directories to the search path.

In your case:

webpack config

var path = require('path');

// ...

  resolve: {
    root: path.resolve('./mydir'),
    extensions: ['', '.js']
  }

consuming module

require('myfile')

or

require('myfile.js')

see also: http://webpack.github.io/docs/configuration.html#resolve-modulesdirectories

This is an old question, but no one responded to the question regarding centering text in a terminal.

/**
 * Centers a string of text in a terminal window
 *
 * @param string $text The text to center
 * @param string $pad_string If set, the string to pad with (eg. '=' for a nice header)
 *
 * @return string The padded result, ready to echo
 */
function center($text, $pad_string = ' ') {
    $window_size = (int) `tput cols`;
    return str_pad($text, $window_size, $pad_string, STR_PAD_BOTH)."\n";
}

echo center('foo');
echo center('bar baz', '=');

Alert will block the program flow so you can just write the following.

echo ("<script LANGUAGE='JavaScript'>
    window.alert('Succesfully Updated');
    window.location.href='http://someplace.com';
    </script>");

looks like you have maven project and so resources are in classpath by

go for

getClass().getResource("classpath:storedProcedures.sql")

Note that if you use more than 9 capture groups you have to use the syntax ${10}.

$10 or \10 or \{10} will not work.

you can use an object

var days = {
   'Mon': 'Monday',
   'etc..': 'etc..',
   'Fri': 'Friday'
}

var date = new Date().toString().split(' ')[0]; //get day abreviation first
console.log(days[date]);

This middleware will output every SQL query to your console, with color highlighting and execution time, it's been invaluable for me in optimizing some tricky requests

http://djangosnippets.org/snippets/290/

foreach (DataRow dr in ds.Tables[0].Rows)
{
    //your code here
}

code {_x000D_
    background: black;_x000D_
    color: white;_x000D_
    display: inline-block;_x000D_
    vertical-align: middle;_x000D_
}

<p>Some text <code>A<br />B<br />C<br />D</code> continues afterward.</p>

Tested and works in Safari 5 and IE6+.

Try this,

string Date = datePicker1.SelectedDate.Value.ToString("dd-MMM-yyyy");

It worked for me the output format will be '02-May-2016'

Also another important note. You have to set android.permission.ACCESS_NETWORK_STATE in your AndroidManifest.xml for this to work.

_ how could I have found myself the information I needed in the online documentation?

You just have to read the documentation the the classes properly enough and you'll find all answers you are looking for. Check out the documentation on ConnectivityManager. The description tells you what to do.

Here I have a CSS-selector based on bobince's answer to select any focusable HTML element:

  a[href]:not([tabindex='-1']),
  area[href]:not([tabindex='-1']),
  input:not([disabled]):not([tabindex='-1']),
  select:not([disabled]):not([tabindex='-1']),
  textarea:not([disabled]):not([tabindex='-1']),
  button:not([disabled]):not([tabindex='-1']),
  iframe:not([tabindex='-1']),
  [tabindex]:not([tabindex='-1']),
  [contentEditable=true]:not([tabindex='-1'])
  {
      /* your CSS for focusable elements goes here */
  }

or a little more beautiful in SASS:

a[href],
area[href],
input:not([disabled]),
select:not([disabled]),
textarea:not([disabled]),
button:not([disabled]),
iframe,
[tabindex],
[contentEditable=true]
{
    &:not([tabindex='-1'])
    {
        /* your SCSS for focusable elements goes here */
    }
}

I've added it as an answer, because that was, what I was looking for, when Google redirected me to this Stackoverflow question.

EDIT: There is one more selector, which is focusable:

[contentEditable=true]

However, this is used very rarely.

mapStateToProps receives the state and props and allows you to extract props from the state to pass to the component.

mapDispatchToProps receives dispatch and props and is meant for you to bind action creators to dispatch so when you execute the resulting function the action gets dispatched.

I find this only saves you from having to do dispatch(actionCreator()) within your component thus making it a bit easier to read.

https://github.com/reactjs/react-redux/blob/master/docs/api.md#arguments

Using your code you can do something like this in plain JavaScript using the cloneNode() method:

// Create a clone of element with id ddl_1:
let clone = document.querySelector('#ddl_1').cloneNode( true );

// Change the id attribute of the newly created element:
clone.setAttribute( 'id', newId );

// Append the newly created element on element p 
document.querySelector('p').appendChild( clone );

Or using jQuery clone() method (not the most efficient):

$('#ddl_1').clone().attr('id', newId).appendTo('p'); // append to where you want

The markup for that document could look like the following:

<body>
     <header>...</header>
     <nav>...</nav>
     <article>
          <section>
               ...
          </section>
     </article>
     <aside>...</aside>
     <footer>...</footer>
</body>

You may find more information in this article on A List Apart.

WebClient to fetch the contents from the remote url and JavaScriptSerializer or Json.NET to deserialize the JSON into a .NET object. For example you define a model class which will reflect the JSON structure and then:

using (var client = new WebClient())
{
    var json = client.DownloadString("http://example.com/json");
    var serializer = new JavaScriptSerializer();
    SomeModel model = serializer.Deserialize<SomeModel>(json);
    // TODO: do something with the model
}

There are also some REST client frameworks you may checkout such as RestSharp.

Yes.

1. You can set a flag/condition.
2. Call invalidateOptionsMenu() when you want to hide the option. This will call onCreateOptionsMenu().
3. In onCreateOptionsMenu(), check for the flag/condition and show or hide it the following way:

MenuItem item = menu.findItem(R.id.menu_Done);

if (flag/condition)) {
  item.setVisible(false); 
} else { }

I would write it this way

UPDATE s
SET    OrgAddress1 = bd.OrgAddress1,    OrgAddress2 = bd.OrgAddress2,    
     ...    DestZip = bd.DestZip
--select s.OrgAddress1, bd.OrgAddress1, s.OrgAddress2, bd.OrgAddress2, etc 
FROM    Shipment s
JOIN ProfilerTest.dbo.BookingDetails bd on  bd.MyID =s.MyID2
WHERE    bd.MyID = @MyId 

This way the join is explicit as implicit joins are a bad thing IMHO. You can run the commented out select (usually I specify the fields I'm updating old and new values next to each other) to make sure that what I am going to update is exactly what I meant to update.

This should work:

 cat "$API" >> "$CONFIG"

You need to use the >> operator to append to a file. Redirecting with > causes the file to be overwritten. (truncated).

Please use the below command to get the IP address of the running container.

$ ip addr

Here is how I do custom CSS for Internet Explorer:

In my JavaScript file:

function isIE () {
      var myNav = navigator.userAgent.toLowerCase();
      return (myNav.indexOf('msie') != -1) ? parseInt(myNav.split('msie')[1]) : false;
}

jQuery(document).ready(function(){
    if(var_isIE){
            if(var_isIE == 10){
                jQuery("html").addClass("ie10");
            }
            if(var_isIE == 8){
                jQuery("html").addClass("ie8");
                // you can also call here some function to disable things that 
                //are not supported in IE, or override browser default styles.
            }
        }
    });

And then in my CSS file, y define each different style:

.ie10 .some-class span{
    .......
}
.ie8 .some-class span{
    .......
}

It is very important that you tell the browser what type of data you are sending it. The difference should be obvious. Try viewing the output of the following PHP file in your browser;

<?php
header('Content-Type:text/html');
?>
<p>Hello</p>

You will see:

hello

(note that you will get the same results if you miss off the header line in this case - text/html is php's default)

Change it to text/plain

<?php
header('Content-Type:text/plain');
?>
<p>Hello</p>

You will see:

<p>Hello</p>

Why does this matter? If you have something like the following in a php script that, for example, is used by an ajax request:

<?php
header('Content-Type:text/html');
print "Your name is " . $_GET['name']

Someone can put a link to a URL like http://example.com/test.php?name=%3Cscript%20src=%22http://example.com/eviljs%22%3E%3C/script%3E on their site, and if a user clicks it, they have exposed all their information on your site to whoever put up the link. If you serve the file as text/plain, you are safe.

Note that this is a silly example, it's more likely that the bad script tag would be added by the attacker to a field in the database or by using a form submission.

What you are looking for is this:

$(".subclass", this).css("visibility","visible");

Add the this after the class $(".subclass", this)

Use json_decode($json_string, TRUE) function to convert the JSON object to an array.

Example:

$json_string   = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

$my_array_data = json_decode($json_string, TRUE);

NOTE: The second parameter will convert decoded JSON string into an associative array.

===========

Output:

var_dump($my_array_data);

array(5) {

    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

Like it has been said few times, you need to change your selector to

$("input[name='bla[]']")

But I want to add, you have to use single or double quotes when using [] in selector.

@Taesung Shin is right, but then just some more magic to make it into a data.frame. I added a "x|y" line to avoid ambiguities:

df <- data.frame(ID=11:13, FOO=c('a|b','b|c','x|y'))
foo <- data.frame(do.call('rbind', strsplit(as.character(df$FOO),'|',fixed=TRUE)))

Or, if you want to replace the columns in the existing data.frame:

within(df, FOO<-data.frame(do.call('rbind', strsplit(as.character(FOO), '|', fixed=TRUE))))

Which produces:

Xamarin is now owned by Microsoft So it completely free to use on Windows and mac as well.

I was able to achieve that by wrapping Button with ConstraintLayout:

<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.google.android.material.appbar.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:elevation="0dp">

        <androidx.appcompat.widget.Toolbar
            android:id="@+id/top_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@color/white_color">

            <androidx.constraintlayout.widget.ConstraintLayout
                android:layout_width="match_parent"
                android:layout_marginTop="10dp"
                android:layout_height="wrap_content">

                <TextView
                    android:id="@+id/cancel"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="@string/cancel"
                    android:layout_marginStart="5dp"
                    app:layout_constraintBottom_toBottomOf="parent"
                    app:layout_constraintLeft_toLeftOf="parent"
                    app:layout_constraintTop_toTopOf="parent" />

                <Button
                    android:id="@+id/btn_publish"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="@string/publish"
                    android:background="@drawable/button_publish_rounded"
                    app:layout_constraintTop_toTopOf="parent"
                    app:layout_constraintBottom_toBottomOf="parent"
                    app:layout_constraintEnd_toEndOf="parent"
                    android:layout_marginEnd="10dp"
                    app:layout_constraintLeft_toRightOf="@id/cancel"
                    tools:layout_editor_absoluteY="0dp" />

            </androidx.constraintlayout.widget.ConstraintLayout>

        </androidx.appcompat.widget.Toolbar>

    </com.google.android.material.appbar.AppBarLayout>

</androidx.coordinatorlayout.widget.CoordinatorLayout>

You may create a drawable resourcebutton_publish_rounded, define the button properties and assign this file to button's android:background property:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/green" />
    <corners android:radius="100dp" />
</shape>

Here's an easier way:

sudo apt-get install maven

More details are here.

You can make use of location service available in @angular/common and via this below code you can get the location or current URL

import { Component, OnInit } from '@angular/core';
import { Location } from '@angular/common';
import { Router } from '@angular/router';

@Component({
  selector: 'app-top-nav',
  templateUrl: './top-nav.component.html',
  styleUrls: ['./top-nav.component.scss']
})
export class TopNavComponent implements OnInit {

  route: string;

  constructor(location: Location, router: Router) {
    router.events.subscribe((val) => {
      if(location.path() != ''){
        this.route = location.path();
      } else {
        this.route = 'Home'
      }
    });
  }

  ngOnInit() {
  }

}

here is the reference link from where I have copied thing to get location for my project. https://github.com/elliotforbes/angular-2-admin/blob/master/src/app/common/top-nav/top-nav.component.ts

I need this so often that I created a function in my ~/.bashrc file:

chmodf() {
        find $2 -type f -exec chmod $1 {} \;
}
chmodd() {
        find $2 -type d -exec chmod $1 {} \;
}

Now I can use these shortcuts:

chmodd 0775 .
chmodf 0664 .

Use isMovingFromParentViewController

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(true)

    if self.isMovingFromParentViewController {
        // current viewController is removed from parent
        // do some work
    }
}

You can use this extension:

extension String {

    static func isNilOrEmpty(string: String?) -> Bool {
        guard let value = string else { return true }

        return value.trimmingCharacters(in: .whitespaces).isEmpty
    }

}

and then use it like this:

let isMyStringEmptyOrNil = String.isNilOrEmpty(string: myString)

To answer this question it's critical whether the Java VM is in CLIENT or SERVER mode. You can specify "-client" or "-server" options. Otherwise java uses internal rules; basically win32 is always client and Linux is always server, but see the table here:

http://docs.oracle.com/javase/6/docs/technotes/guides/vm/server-class.html

Sun/Oracle jre6u18 doc says re client: the VM gets 1/2 of physical memory if machine has <= 192MB; 1/4 of memory if machine has <= 1Gb; max 256Mb. In my test on a 32bit WindowsXP system with 2Gb phys mem, Java allocated 256Mb, which agrees with the doc.

Sun/Oracle jre6u18 doc says re server: same as client, then adds confusing language: for 32bit JVM the default max is 1Gb, and for 64 bit JVM the default is 32Gb. In my test on a 64bit linux machine with 8Gb physical, Java allocates 2Gb, which is 1/4 of physical; on a 64bit linux machine with 128Gb physical Java allocates 32Gb, again 1/4 of physical.

Thanks to this SO post for guiding me:

Definition of server-class machine changed recently?

As pointed out in this comment How do you check in python whether a string contains only numbers? the isdigit() method is not totally accurate for this use case, because it returns True for some digit-like characters:

>>> "\u2070".isdigit() # unicode escaped 'superscript zero' 
True

If this needs to be avoided, the following simple function checks, if all characters in a string are a digit between "0" and "9":

import string

def contains_only_digits(s):
    # True for "", "0", "123"
    # False for "1.2", "1,2", "-1", "a", "a1"
    for ch in s:
        if not ch in string.digits:
            return False
    return True

Used in the example from the question:

if len(isbn) == 10 and contains_only_digits(isbn):
    print ("Works")

I was able to work it out only after adding those two TOGETHER:

dependencies {
...
implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'
...
}

in my build.gradle (Module:app) file

and then press the sync now button

Laravel has inbuilt support for multiple database systems, you need to provide connection details in config/database.php file

return [
    'default' => env('DB_CONNECTION', 'mysql'),

    'connections' => [
        'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix' => '',
            'strict' => false,
            'engine' => null,
        ],
'mysqlOne' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST_ONE', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE_ONE', 'forge'),
            'username' => env('DB_USERNAME_ONE', 'forge'),
            'password' => env('DB_PASSWORD_ONE', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix' => '',
            'strict' => false,
            'engine' => null,
        ],
];

Once you have this you can create two base model class for each connection and define the connection name in those models

//BaseModel.php
protected $connection = 'mysql';

//BaseModelOne.php
protected $connection = 'mysqlOne';

You can extend these models to create more models for tables in each DB.

You can use a GROUP BY to group items by type and id. Then you can use the MAX() Aggregate function to get the most recent service month. The below returns a result set with ChargeId, ChargeType, and MostRecentServiceMonth

SELECT
  CHARGEID,
  CHARGETYPE,
  MAX(SERVICEMONTH) AS "MostRecentServiceMonth"
FROM INVOICE
GROUP BY CHARGEID, CHARGETYPE

In layman terms we can say that Persistence Context is an environment where entities are managed, i.e it syncs "Entity" with the database.

If it's possible that the value that you're adding to your URL can have reserved characters (as defined by section 2 of RFC 3986), you might have to refine your percent-escaping. Notably, while & and + are valid characters in a URL, they're not valid within a URL query parameter value (because & is used as delimiter between query parameters which would prematurely terminate your value, and + is translated to a space character). Unfortunately, the standard percent-escaping leaves those delimiters unescaped.

Thus, you might want to percent escape all characters that are not within RFC 3986's list of unreserved characters:

Characters that are allowed in a URI but do not have a reserved purpose are called unreserved. These include uppercase and lowercase letters, decimal digits, hyphen, period, underscore, and tilde.

     unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"

Later, in section 3.4, the RFC further contemplates adding ? and / to the list of allowed characters within a query:

The characters slash ("/") and question mark ("?") may represent data within the query component. Beware that some older, erroneous implementations may not handle such data correctly when it is used as the base URI for relative references (Section 5.1), apparently because they fail to distinguish query data from path data when looking for hierarchical separators. However, as query components are often used to carry identifying information in the form of "key=value" pairs and one frequently used value is a reference to another URI, it is sometimes better for usability to avoid percent- encoding those characters.

Nowadays, you'd generally use URLComponents to percent escape the query value:

var address = "American Tourister, Abids Road, Bogulkunta, Hyderabad, Andhra Pradesh, India"
var components = URLComponents(string: "http://maps.googleapis.com/maps/api/geocode/json")!
components.queryItems = [URLQueryItem(name: "address", value: address)]
let url = components.url!

By the way, while it's not contemplated in the aforementioned RFC, section 5.2, URL-encoded form data, of the W3C HTML spec says that application/x-www-form-urlencoded requests should also replace space characters with + characters (and includes the asterisk in the characters that should not be escaped). And, unfortunately, URLComponents won't properly percent escape this, so Apple advises that you manually percent escape it before retrieving the url property of the URLComponents object:

// configure `components` as shown above, and then:

components.percentEncodedQuery = components.percentEncodedQuery?.replacingOccurrences(of: "+", with: "%2B")
let url = components.url!

For Swift 2 rendition, where I manually do all of this percent escaping myself, see the previous revision of this answer.

The PowerShell is almost exactly the same.

$webclient = new-object System.Net.WebClient
$webclient.Credentials = new-object System.Net.NetworkCredential($username, $password, $domain)
$webpage = $webclient.DownloadString($url)

sschuberth comments

git-what-branch (Perl script, see below) does not seem to be maintained anymore. git-when-merged is an alternative written in Python that's working very well for me.

It is based on "Find merge commit which include a specific commit".

git when-merged [OPTIONS] COMMIT [BRANCH...]

Find when a commit was merged into one or more branches.
Find the merge commit that brought COMMIT into the specified BRANCH(es).

Specifically, look for the oldest commit on the first-parent history of BRANCH that contains the COMMIT as an ancestor.

Original answer September 2010:

Sebastien Douche just twitted (16 minutes before this SO answer):

git-what-branch: Discover what branch a commit is on, or how it got to a named branch

This is a Perl script from Seth Robertson that seems very interesting:

SYNOPSIS

git-what-branch [--allref] [--all] [--topo-order | --date-order ]
[--quiet] [--reference-branch=branchname] [--reference=reference]
<commit-hash/tag>...

OVERVIEW

Tell us (by default) the earliest causal path of commits and merges to cause the requested commit got onto a named branch. If a commit was made directly on a named branch, that obviously is the earliest path.

By earliest causal path, we mean the path which merged into a named branch the earliest, by commit time (unless --topo-order is specified).

PERFORMANCE

If many branches (e.g. hundreds) contain the commit, the system may take a long time (for a particular commit in the Linux tree, it took 8 second to explore a branch, but there were over 200 candidate branches) to track down the path to each commit.
Selection of a particular --reference-branch --reference tag to examine will be hundreds of times faster (if you have hundreds of candidate branches).

EXAMPLES

 # git-what-branch --all 1f9c381fa3e0b9b9042e310c69df87eaf9b46ea4
 1f9c381fa3e0b9b9042e310c69df87eaf9b46ea4 first merged onto master using the following minimal temporal path:
   v2.6.12-rc3-450-g1f9c381 merged up at v2.6.12-rc3-590-gbfd4bda (Thu May  5 08:59:37 2005)
   v2.6.12-rc3-590-gbfd4bda merged up at v2.6.12-rc3-461-g84e48b6 (Tue May  3 18:27:24 2005)
   v2.6.12-rc3-461-g84e48b6 is on master
   v2.6.12-rc3-461-g84e48b6 is on v2.6.12-n
   [...]

This program does not take into account the effects of cherry-picking the commit of interest, only merge operations.

h = fspecial('average', n);
filter2(h, img);

See doc fspecial: h = fspecial('average', n) returns an averaging filter. n is a 1-by-2 vector specifying the number of rows and columns in h.

The following will give you the hex encoding for the low byte of each character, which looks like what you're asking for:

StringBuilder sb = new StringBuilder();
foreach (char c in asciiString)
{
    uint i = (uint)c;
    sb.AppendFormat("{0:X2}", (i & 0xff));
}
return sb.ToString();

Using ONLY css is impossbile. In fact, all form elements are impossible to customize to look in the same way on all browsers only with css. You can try niceforms though ;)

You can try the following:

remove_column :table_name, :column_name

(Official documentation)

Try this-

CREATE PROCEDURE simpleproc (IN name varchar(50),IN user_name varchar(50),IN branch varchar(50))
BEGIN
    insert into student (name,user_name,branch) values (name ,user_name,branch);
END

document.getElementById('mybox').style.display = "block";

Actually it's way easier to use ToolBucket plugin for Notepad++ to multiline replace.

To activate it just go to N++ menu:

Plugins > Plugin Manager > Show Plugin Manager > Check ToolBucket > Install.

Restart N++ and press ALT + SHIFT + F to multiline edit.

The answers seems a bit over complicated. I hope I didn't misunderstand the question.

If you simply want to open a fancy box from a click to an "A" tag. Just set your html to

<a id="my_fancybox" href="#contentdiv">click me</a>

The contents of your box will be inside of a div with id "contentdiv" and in your javascript you can initialize fancybox like this:

$('#my_fancybox').fancybox({
    'autoScale': true,
    'transitionIn': 'elastic',
    'transitionOut': 'elastic',
    'speedIn': 500,
    'speedOut': 300,
    'autoDimensions': true,
    'centerOnScroll': true,
});

This will show a fancybox containing "contentdiv" when your anchor tag is clicked.

Best practices are to add getter method for that :

getImageURI() {
  return "images/" + this.props.image;
}

<img className="image" src={this.getImageURI()} />

Then , if you have more logic later on, you can maintain the code smoothly.

Add HttpProtocolOptions Unsafe to your apache config file and restart the apache server. It shows the error details.

Dim FindRow as Range

Set FindRow = Range("A:A").Find(What:="ProjTemp", _' This is what you are searching for
                   After:=.Cells(.Cells.Count), _ ' This is saying after the last cell in the_
                                                  ' column i.e. the first
                   LookIn:=xlValues, _ ' this says look in the values of the cell not the formula
                   LookAt:=xlWhole, _ ' This look s for EXACT ENTIRE MATCH
                   SearchOrder:=xlByRows, _ 'This look down the column row by row 
                                            'Larger Ranges with multiple columns can be set to 
                                            ' look column by column then down 
                   MatchCase:=False) ' this says that the search is not case sensitive

If Not FindRow  Is Nothing Then ' if findrow is something (Prevents Errors)
    FirstRow = FindRow.Row      ' set FirstRow to the first time a match is found
End If

If you would like to get addition ones you can use:

Do Until FindRow Is Nothing
    Set FindRow = Range("A:A").FindNext(after:=FindRow)
    If FindRow.row = FirstRow Then
        Exit Do
    Else ' Do what you'd like with the additional rows here.

    End If
Loop

Here is my answer:

    def draw_text(text, font_name, size, color, x, y, align="nw"):
        font = pg.font.Font(font_name, size)
        text_surface = font.render(text, True, color)
        text_rect = text_surface.get_rect()
        if align == "nw":
            text_rect.topleft = (x, y)
        if align == "ne":
            text_rect.topright = (x, y)
        if align == "sw":
            text_rect.bottomleft = (x, y)
        if align == "se":
            text_rect.bottomright = (x, y)
        if align == "n":
            text_rect.midtop = (x, y)
        if align == "s":
            text_rect.midbottom = (x, y)
        if align == "e":
            text_rect.midright = (x, y)
        if align == "w":
            text_rect.midleft = (x, y)
        if align == "center":
            text_rect.center = (x, y)
        screen.blit(text_surface, text_rect)

Of course, you'll need to import pygame, a font and a screen, but this is just a def to add on to the rest of the code, and then call "draw_text".

onCreate(Bundle savedInstanceState) you will get the Bundle null when activity get starts first time and it will get in use when activity orientation get changed .......

http://www.gitshah.com/2011/03/how-to-handle-screen-orientation_28.html

Android provides another elegant way of achieving this. To achieve this, we have to override a method called onSaveInstanceState(). Android platform allows the users to save any instance state. Instance state can be saved in the Bundle. Bundle is passed as argument to the onSaveInstanceState method.

we can load the saved instance state from the Bundle passed as argument to the onCreate method. We can also load the saved instance state in onRestoreInstanceState method. But I will leave that for the readers to figure out.

• document.ready is a jQuery event, it runs when the DOM is ready, e.g. all elements are there to be found/used, but not necessarily all content.
• window.onload fires later (or at the same time in the worst/failing cases) when images and such are loaded, so if you're using image dimensions for example, you often want to use this instead.

I've used it to create objects based on memory containing messages received from the network.

This is my solution by overriding default Spring Boot /error handler

package com.mypackage;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.web.ErrorAttributes;
import org.springframework.core.annotation.AnnotationUtils;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.util.Assert;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Map;

/**
 * This controller is vital in order to handle exceptions thrown in Filters.
 */
@RestController
@RequestMapping("/error")
public class ErrorController implements org.springframework.boot.autoconfigure.web.ErrorController {

    private final static Logger LOGGER = LoggerFactory.getLogger(ErrorController.class);

    private final ErrorAttributes errorAttributes;

    @Autowired
    public ErrorController(ErrorAttributes errorAttributes) {
        Assert.notNull(errorAttributes, "ErrorAttributes must not be null");
        this.errorAttributes = errorAttributes;
    }

    @Override
    public String getErrorPath() {
        return "/error";
    }

    @RequestMapping
    public ResponseEntity<Map<String, Object>> error(HttpServletRequest aRequest, HttpServletResponse response) {
        RequestAttributes requestAttributes = new ServletRequestAttributes(aRequest);
        Map<String, Object> result =     this.errorAttributes.getErrorAttributes(requestAttributes, false);

        Throwable error = this.errorAttributes.getError(requestAttributes);

        ResponseStatus annotation =     AnnotationUtils.getAnnotation(error.getClass(), ResponseStatus.class);
        HttpStatus statusCode = annotation != null ? annotation.value() : HttpStatus.INTERNAL_SERVER_ERROR;

        result.put("status", statusCode.value());
        result.put("error", statusCode.getReasonPhrase());

        LOGGER.error(result.toString());
        return new ResponseEntity<>(result, statusCode) ;
    }

}

How about this?

formdata.append('tags', JSON.stringify(tags));

... and, correspondingly, using json_decode on server to deparse it. See, the second value of FormData.append can be...

a Blob, File, or a string, if neither, the value is converted to a string

The way I see it, your tags array contains objects (@Musa is right, btw; making this_tag an Array, then assigning string properties to it makes no sense; use plain object instead), so native conversion (with toString()) won't be enough. JSON'ing should get the info through, though.

As a sidenote, I'd rewrite the property assigning block just into this:

tags.push({article: article, gender: gender, brand: brand});
