What you have above is an object, not an array.

To make an array use [ & ] to surround your objects.

userTestStatus = [
  { "id": 0, "name": "Available" },
  { "id": 1, "name": "Ready" },
  { "id": 2, "name": "Started" }
];

Aside from that TypeScript is a superset of JavaScript so whatever is valid JavaScript will be valid TypeScript so no other changes are needed.

Feedback clarification from OP... in need of a definition for the model posted

You can use the types defined here to represent your object model:

type MyType = {
    id: number;
    name: string;
}

type MyGroupType = {
    [key:string]: MyType;
}

var obj: MyGroupType = {
    "0": { "id": 0, "name": "Available" },
    "1": { "id": 1, "name": "Ready" },
    "2": { "id": 2, "name": "Started" }
};
// or if you make it an array
var arr: MyType[] = [
    { "id": 0, "name": "Available" },
    { "id": 1, "name": "Ready" },
    { "id": 2, "name": "Started" }
];

Well, there is no shortcut to do it as per my findings, but somehow you
an achieve it in few simple steps

First you have to declare a bean of type 'ProtobufJsonFormatHttpMessageConverter'

@Bean  
@Primary  
public ProtobufJsonFormatHttpMessageConverter protobufHttpMessageConverter() {  
  return new ProtobufJsonFormatHttpMessageConverter(JsonFormat.parser(), JsonFormat.printer());  
}  

Then you can just write an Utility class like ResponseBuilder, because it can parse the request by default but without these changes it can not produce Json response. and then you can write few methods to convert the response types to its related object type.

public static <T> T build(Message message, Class<T> type) {
  Printer printer = JsonFormat.printer();
  Gson gson = new Gson();
  try {
    return gson.fromJson(printer.print(message), type);
  } catch (JsonSyntaxException | InvalidProtocolBufferException e) {
    throw new ApiException(HttpStatus.INTERNAL_SERVER_ERROR, "Response   conversion Error", e);
  }
}

Then you can call this method from your controller class as last line like -

return ResponseBuilder.build(<returned_service_object>, <Type>);

Hope this will help you to implement protobuf in json format.

I had a similar problem where i have to center the toolTip. React setState in componentDidUpdate did put me in infinite loop, i tried condition it worked. But i found using in ref callback gave me simpler and clean solution, if you use inline function for ref callback you will face the null problem for every component update. So use function reference in ref callback and set the state there, which will initiate the re-render

I'm afraid you can't combine these functions, ie. you gotta do something like this:-

myData.unique().sort();

Alternatively you can implement a kind of sortedset (as available in other languages) - which carries both the notion of sorting and removing duplicates, as you require.

Hope this helps.

TL;DR

find /my/dir/ -printf "%P\n" | tar -czf mydir.tgz --no-recursion -C /my/dir/ -T -

With some conditions (archive only files, dirs and symlinks):

find /my/dir/ -printf "%P\n" -type f -o -type l -o -type d | tar -czf mydir.tgz --no-recursion -C /my/dir/ -T -

Explanation

The below unfortunately includes a parent directory ./ in the archive:

tar -czf mydir.tgz -C /my/dir .

You can move all the files out of that directory by using the --transform configuration option, but that doesn't get rid of the . directory itself. It becomes increasingly difficult to tame the command.

You could use $(find ...) to add a file list to the command (like in magnus' answer), but that potentially causes a "file list too long" error. The best way is to combine it with tar's -T option, like this:

find /my/dir/ -printf "%P\n" -type f -o -type l -o -type d | tar -czf mydir.tgz --no-recursion -C /my/dir/ -T -

Basically what it does is list all files (-type f), links (-type l) and subdirectories (-type d) under your directory, make all filenames relative using -printf "%P\n", and then pass that to the tar command (it takes filenames from STDIN using -T -). The -C option is needed so tar knows where the files with relative names are located. The --no-recursion flag is so that tar doesn't recurse into folders it is told to archive (causing duplicate files).

If you need to do something special with filenames (filtering, following symlinks etc), the find command is pretty powerful, and you can test it by just removing the tar part of the above command:

$ find /my/dir/ -printf "%P\n" -type f -o -type l -o -type d
> textfile.txt
> documentation.pdf
> subfolder2
> subfolder
> subfolder/.gitignore

For example if you want to filter PDF files, add ! -name '*.pdf'

$ find /my/dir/ -printf "%P\n" -type f ! -name '*.pdf' -o -type l -o -type d
> textfile.txt
> subfolder2
> subfolder
> subfolder/.gitignore

Non-GNU find

The command uses printf (available in GNU find) which tells find to print its results with relative paths. However, if you don't have GNU find, this works to make the paths relative (removes parents with sed):

find /my/dir/ -type f -o -type l -o -type d | sed s,^/my/dir/,, | tar -czf mydir.tgz --no-recursion -C /my/dir/ -T -

I won't address the READ UNCOMMITTED argument, just your original question.

Yes, you need WITH(NOLOCK) on each table of the join. No, your queries are not the same.

Try this exercise. Begin a transaction and insert a row into table1 and table2. Don't commit or rollback the transaction yet. At this point your first query will return successfully and include the uncommitted rows; your second query won't return because table2 doesn't have the WITH(NOLOCK) hint on it.

You can also use echo to remove blank spaces, either at the beginning or at the end of the string, but also repeating spaces inside the string.

$ myVar="    kokor    iiij     ook      "
$ echo "$myVar"
    kokor    iiij     ook      
$ myVar=`echo $myVar`
$
$ # myVar is not set to "kokor iiij ook"
$ echo "$myVar"
kokor iiij ook

Quoting from the gcc website:

C++11 features are available as part of the "mainline" GCC compiler in the trunk of GCC's Subversion repository and in GCC 4.3 and later. To enable C++0x support, add the command-line parameter -std=c++0x to your g++ command line. Or, to enable GNU extensions in addition to C++0x extensions, add -std=gnu++0x to your g++ command line. GCC 4.7 and later support -std=c++11 and -std=gnu++11 as well.

So probably you use a version of g++ which doesn't support -std=c++11. Try -std=c++0x instead.

Availability of C++11 features is for versions >= 4.3 only.

Just to elaborate on Heyvoon's (2015.06.08) response using Powershell, this simple Powershell script should give you detail on %path%

$env:Path -split ";" | % {"$(test-path $_);$_"}

generating this kind of output which you can independently verify

True;C:\WINDOWS
True;C:\WINDOWS\system32
True;C:\WINDOWS\System32\Wbem
False;C:windows\System32\windowsPowerShell\v1.0\
False;C:\Program Files (x86)\Java\jre7\bin

to reassemble for updating Path:

$x=$null;foreach ($t in ($env:Path -split ";") ) {if (test-path $t) {$x+=$t+";"}};$x

Just adding this for reference in case anybody needs to restart and immediatly run a command.

I'm using this approach just to clear RAM from the system. Make sure you have deleted all objects no longer required. Maybe gc() can also help before hand. But nothing will clear RAM better as restarting the R session.

library(rstudioapi)
restartSession(command = "print('x')")

In SQL Developer you can right-click on the package body then select RUN. The 'Run PL/SQL' window will let you edit the PL/SQL Block. Clicking OK will give you a window pane titled 'Output Variables - Log' with an output variables tab. You can select your output variables on the left and the result is shown on the right side. Very handy and fast.

I've used Rapid with T-SQL and I think there was something similiar to this.

Writing your own delcare-begin-end script where you loop through the cursor, as with DCookie's example, is always a good exercise to do every now and then. It will work with anything and you will know that your code works.

At least for the GitHub Flavoured Markdown, you can give the illusion by making all the non-header row entries bold with the regular __ or ** formatting:

|Regular | text | in header | turns bold |
|-|-|-|-|
| __So__ | __bold__ | __all__ | __table entries__ |
| __and__ | __it looks__ | __like a__ | __"headerless table"__ |

Do not use regular expressions to parse HTML.

But if you ever need to find all regexp matches in a string, use the findall function.

import re
line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
matches = re.findall('<form>(.*?)</form>', line, re.DOTALL)
print(matches)

# Output: ['Form 1', 'Form 2']

Swift 4

How about this small trick?

func showToast(controller: UIViewController, message : String, seconds: Double) {
    let alert = UIAlertController(title: nil, message: message, preferredStyle: .alert)
    alert.view.backgroundColor = UIColor.black
    alert.view.alpha = 0.6
    alert.view.layer.cornerRadius = 15

    controller.present(alert, animated: true)

    DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + seconds) {
        alert.dismiss(animated: true)
    }
}

Example of calling:

showToast(controller: self, message : "This is a test", seconds: 2.0)

Output:

I always use this command to remove those untracked files. One-line, Unix-style, clean output:

git ls-files --ignored --exclude-standard | sed 's/.*/"&"/' | xargs git rm -r --cached

It lists all your ignored files, replace every output line with a quoted line instead to handle paths with spaces inside, and pass everything to git rm -r --cached to remove the paths/files/dirs from the index.

Also, your compare function is incorrect. It needs to return -1, 0, or 1, not a boolean as you have it. The correct compare function would be:

def compare(item1, item2):
    if fitness(item1) < fitness(item2):
        return -1
    elif fitness(item1) > fitness(item2):
        return 1
    else:
        return 0

# Calling
list.sort(key=compare)

Try this request:

Query

SELECT name
FROM   sys.procedures
WHERE  Object_definition(object_id) LIKE '%strHell%'

I got this error when my server process got an exception midway during generating the response and simply closed the connection without saying goodbye. curl still expected data from the connection and complained (rightfully).

In General

You can detect and specify variables for several operating systems like that:

Detect Microsoft Windows

if(WIN32)
    # for Windows operating system in general
endif()

Or:

if(MSVC OR MSYS OR MINGW)
    # for detecting Windows compilers
endif()

Detect Apple MacOS

if(APPLE)
    # for MacOS X or iOS, watchOS, tvOS (since 3.10.3)
endif()

Detect Unix and Linux

if(UNIX AND NOT APPLE)
    # for Linux, BSD, Solaris, Minix
endif()

Your specific linker issue

To solve your issue with the Windows-specific wsock32 library, just remove it from other systems, like that:

if(WIN32)
    target_link_libraries(${PROJECT_NAME} bioutils wsock32)
else
    target_link_libraries(${PROJECT_NAME} bioutils)
endif()

you could use fopen() function.

some example:

$url = 'http://doman.com/path/to/file.mp4';
$destination_folder = $_SERVER['DOCUMENT_ROOT'].'/downloads/';


    $newfname = $destination_folder .'myfile.mp4'; //set your file ext

    $file = fopen ($url, "rb");

    if ($file) {
      $newf = fopen ($newfname, "a"); // to overwrite existing file

      if ($newf)
      while(!feof($file)) {
        fwrite($newf, fread($file, 1024 * 8 ), 1024 * 8 );

      }
    }

    if ($file) {
      fclose($file);
    }

    if ($newf) {
      fclose($newf);
    }

Wipe the data of your Android virtual Device and then start the emulator. Works for me.

check this link. It has helped me with errno 150: http://verysimple.com/2006/10/22/mysql-error-number-1005-cant-create-table-mydbsql-328_45frm-errno-150/

On the top of my head two things come to mind.

• Is your foreign key index a unique name in the whole database (#3 in the list)?
• Are you trying to set the table PK to NULL on update (#5 in the list)?

I'm guessing the problem is with the set NULL on update (if my brains aren't on backwards today as they so often are...).

Edit: I missed the comments on your original post. Unsigned/not unsigned int columns maybe resolved your case. Hope my link helps someone in the future thought.

Thanks to Java 8 you don't need to do the steps below to pass a function to a method, that's what lambdas are for, see Oracle's Lambda Expression tutorial. The rest of this post describes what we used to have to do in the bad old days in order to implement this functionality.

Typically you declare your method as taking some interface with a single method, then you pass in an object that implements that interface. An example is in commons-collections, where you have interfaces for Closure, Transformer, and Predicate, and methods that you pass implementations of those into. Guava is the new improved commons-collections, you can find equivalent interfaces there.

So for instance, commons-collections has org.apache.commons.collections.CollectionUtils, which has lots of static methods that take objects passed in, to pick one at random, there's one called exists with this signature:

static boolean exists(java.util.Collection collection, Predicate predicate) 

It takes an object that implements the interface Predicate, which means it has to have a method on it that takes some Object and returns a boolean.

So I can call it like this:

CollectionUtils.exists(someCollection, new Predicate() {
    public boolean evaluate(Object object) { 
        return ("a".equals(object.toString());
    }
});

and it returns true or false depending on whether someCollection contains an object that the predicate returns true for.

Anyway, this is just an example, and commons-collections is outdated. I just forget the equivalent in Guava.

If you are using Webdriver then the item you are looking for is Selected.

Often times in the render of the checkbox doesn't actually apply the attribute checked unless specified.

So what you would look for in Selenium Webdriver is this

isChecked = e.findElement(By.tagName("input")).Selected;

As there is no Selected in WebDriver Java API, the above code should be as follows:

isChecked = e.findElement(By.tagName("input")).isSelected();

This error would suggest that User::where('email', '=', $userEmail)->first() is returning null, rather than a problem with updating your model.

Check that you actually have a User before attempting to change properties on it, or use the firstOrFail() method.

$UpdateDetails = User::where('email', $userEmail)->first();

if (is_null($UpdateDetails)) {
    return false;
}

or using the firstOrFail() method, theres no need to check if the user is null because this throws an exception (ModelNotFoundException) when a model is not found, which you can catch using App::error() http://laravel.com/docs/4.2/errors#handling-errors

$UpdateDetails = User::where('email', $userEmail)->firstOrFail();

You can do that I believe. It needs root permission. If you want to know where your apk files are stored, open a emulator and then go to

DDMS>File Explorer-> you can see a directory by name "data" -> Click on it and you will see a "app" folder.

Your apks are stored there. In fact just copying a apk directly to the folder works for me with emulators.

Use this syntax for VB.NET 2005/2008 compatibility:

Dim theVar As New List(Of String)(New String() {"one", "two", "three"})

Although the VB.NET 2010 syntax is prettier.

You simply have to use the filter filter (see the documentation) :

<div id="totalPos">{{(tweets | filter:{polarity:'Positive'}).length}}</div>
<div id="totalNeut">{{(tweets | filter:{polarity:'Neutral'}).length}}</div>
<div id="totalNeg">{{(tweets | filter:{polarity:'Negative'}).length}}</div>

Fiddle

The same route reload Angular 6

For the me issue was that I had 2 other Android Emulators running. Once I closed those, I was able to start the new one.

You can also use:

$('#test').context.scrollHeight

C doesn't support exceptions. You can try compiling your C code as C++ with Visual Studio or G++ and see if it'll compile as-is. Most C applications will compile as C++ without major changes, and you can then use the try... catch syntax.

be attention, if path to browser have space (as example "...\Program Files (x86)...") you need add double quotes to value of param.

Example:

-Dwebdriver.firefox.bin="D:\Program Files (x86)\Mozilla Firefox\firefox.exe"

All has been run successfully when added double quotes.

you should remove the vars from the function:

x = x * cs - y * sn; // now x is something different than original vector x
y = x * sn + y * cs;

create new coordinates becomes, to avoid calculation of x before it reaches the second line:

px = x * cs - y * sn; 
py = x * sn + y * cs;

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        DataContext = new ViewModelBase();

The ViewModel:

    private ICommand _clickCommand;
    public ICommand ClickCommand
    {
        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler(() => MyAction(), ()=> CanExecute));
        }
    }
     public bool CanExecute
     {
        get
        {
            // check if executing is allowed, i.e., validate, check if a process is running, etc. 
            return true/false;
        }
     }

    public void MyAction()
    {

    }
}

Command Handler:

 public class CommandHandler : ICommand
{
    private Action _action;
    private Func<bool> _canExecute;

    /// <summary>
    /// Creates instance of the command handler
    /// </summary>
    /// <param name="action">Action to be executed by the command</param>

        return _canExecute.Invoke();
    }

    public void Execute(object parameter)
    {
        _action();
    }
}

I hope this will give you the idea.

If someone is sniffing your plain-text HTTP traffic (or cache/cookies) for passwords just turning the password into a hash won't help - The hash password can be "replayed" just as well as plain-text. The client would need to hash the password with something somewhat random (like the date and time) See the section on "AUTH CRAM-MD5" here: http://www.fehcom.de/qmail/smtpauth.html

I think you may even have a separate table like a monthdetails (Monthno int, monthnames char(15)) and include values:

1 January
2 February 

.... and so on, and then join this table with your existing table in the monthnames column

SELECT t1.*,t2.Monthno from table1 
left outer join monthdetails t2
on t1.monthname=t2.monthnames
order by t2.Monthno 

You can't. It's immediate mode graphics. But you can sort of simulate it by drawing a rectangle over it in the background color with an opacity.

If the image is over something other than a constant color, then it gets quite a bit trickier. You should be able to use the pixel manipulation methods in this case. Just save the area before drawing the image, and then blend that back on top with an opacity afterwards.

I have catched the same exception and found a InnerException: SocketException. in the svclog trace.

After looking in the windows event log I saw an error coming from the System.ServiceModel.Activation.TcpWorkerProcess class.

Are you hosting your wcf service in IIS with netTcpBinding and port sharing?

It seems there is a bug in IIS port sharing feature, check the fix:

My solution is to host your WCF service in a Windows Service.

With Spring, you can use this:

import org.springframework.core.io.ClassPathResource;

// Don't worry when use a not existed directory or a empty directory
// It can be used in @before
String dir = new ClassPathResource(".").getFile().getAbsolutePath()+"/"+"Your Path";

I would modify the example above as follows:

import java.math.BigDecimal;

BigDecimal premium = new BigDecimal("1586.6");
BigDecimal netToCompany = new BigDecimal("708.75");
BigDecimal commission = premium.subtract(netToCompany);
System.out.println(commission + " = " + premium + " - " + netToCompany);

This way you avoid the pitfalls of using string to begin with. Another alternative:

import java.math.BigDecimal;

BigDecimal premium = BigDecimal.valueOf(158660, 2);
BigDecimal netToCompany = BigDecimal.valueOf(70875, 2);
BigDecimal commission = premium.subtract(netToCompany);
System.out.println(commission + " = " + premium + " - " + netToCompany);

I think these options are better than using doubles. In webapps numbers start out as strings anyways.

li{

or replace 50px with whatever you want.

Hope it will help u:

//create a file to write bitmap data

f.createNewFile();

//Convert bitmap to byte array
Bitmap bitmap = your bitmap;

byte[] bitmapdata = bos.toByteArray();

//write the bytes in file
FileOutputStream fos = new FileOutputStream(f);
fos.write(bitmapdata);
fos.flush();
fos.close();

In addition to @KenM's answer, another important distinction is that, when loading in a saved object, you can assign the contents of an Rds file. Not so for Rda

> x <- 1:5
> save(x, file="x.Rda")
> saveRDS(x, file="x.Rds")
> rm(x)

## ASSIGN USING readRDS
> new_x1 <- readRDS("x.Rds")
> new_x1
[1] 1 2 3 4 5

## 'ASSIGN' USING load -- note the result
> new_x2 <- load("x.Rda")
loading in to  <environment: R_GlobalEnv> 
> new_x2
[1] "x"
# NOTE: `load()` simply returns the name of the objects loaded. Not the values. 
> x
[1] 1 2 3 4 5

Well I did a bit of searching around the internet for you and I found this handy link.

Easiest way to find duplicate values in a JavaScript array

You can adapt the sample code that is provided in the above link, courtesy of "swilliams" to your solution.

In Swift3, I have used in this way

var hasAddedGeofencesAtleastOnce: Bool {
    get {
        return UserDefaults.standard.object(forKey: "hasAddedGeofencesAtleastOnce") != nil
    }
}

The answer is great if you are to use that multiple times.

I hope it helps :)

I had the same problem, the first thing that came to mind was repositories. So I checked the build.gradle file for the whole project and added the following code, then synchronized the gradle with project and problem was solved!

allprojects {
    repositories {
        jcenter()
    }
}

You can avoid declaration of global variables by adding them directly to the global object:

(function(global) {

  ...

  global.varName = someValue;

  ...

}(this));

A disadvantage of this method is that global.varName won't exist until that specific line of code is executed, but that can be easily worked around.

You might also consider an application architecture where such globals are held in a closure common to all functions that need them, or as properties of a suitably accessible data storage object.

& 0xFF by itself only ensures that if bytes are longer than 8 bits (allowed by the language standard), the rest are ignored.

And that seems to work fine too?

If the result ends up greater than SHRT_MAX, you get undefined behavior. In that respect both will work equally poorly.

If you had caught the error, you would have seen this:

jsonString, err := json.Marshal(datas)
fmt.Println(err)

// [] json: unsupported type: map[int]main.Foo

The thing is you cannot use integers as keys in JSON; it is forbidden. Instead, you can convert these values to strings beforehand, for instance using strconv.Itoa.

See this post for more details: https://stackoverflow.com/a/24284721/2679935

Although View.getVisibility() does get the visibility, its not a simple true/false. A view can have its visibility set to one of three things.

View.VISIBLE The view is visible.

View.INVISIBLE The view is invisible, but any spacing it would normally take up will still be used. Its "invisible"

View.GONE The view is gone, you can't see it and it doesn't take up the "spot".

So to answer your question, you're looking for:

if (myImageView.getVisibility() == View.VISIBLE) {
    // Its visible
} else {
    // Either gone or invisible
}

I had this issue.

The way I fixed it was by completely deleting the Pod implementing and re-implementing it. Make sure to delete "Copy Pods Resources" and "Check Pods Manifest.lock" from "Build Phases" on all targets as stated here: How to remove CocoaPods from a project?

Delete empty rows from Excel after your last row of data!

Some times empty rows in Excel are still considered as data, therefore trying to import them in a table with one or more non nullable columns violates the constrains of the column.

Solution: select all of the empty rows on your sheet, even those after your last row of data, and click delete rows.

Obviously, if some of your data really does vioalte any of your table's constraints, then just fix your data to match the rules of your database..

No new Calendar needs to be created, SimpleDateFormat already uses a Calendar underneath.

SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy", Locale.EN_US);
Date date = sdf.parse("Mon Mar 14 16:02:37 GMT 2011"));// all done
Calendar cal = sdf.getCalendar();

There is way with add class and css style

![pic][logo]{.classname}

then write down link and css below

[logo]: (picurl)

<style type="text/css">
    .classname{
        width: 200px;
    }

I just tried on windows XP, it worked

local computer: sc \\. delete [service-name]

  Deleting services in Windows Server 2003

  We can use sc.exe in the Windows Server 2003 to control services, create services and delete services. Since some people thought they must directly modify the registry to delete a service, I would like to share how to use sc.exe to delete a service without directly modifying the registry so that decreased the possibility for system failures.

  To delete a service: 

  Click “start“ - “run“, and then enter “cmd“ to open Microsoft Command Console.

  Enter command:

  sc servername delete servicename

  For instance, sc \\dc delete myservice

  (Note: In this example, dc is my Domain Controller Server name, which is not the local machine, myservice is the name of the service I want to delete on the DC server.)

  Below is the official help of all sc functions:

  DESCRIPTION:
    SC is a command line program used for communicating with the
    NT Service Controller and services. 
  USAGE:
          sc

the first thing we need is the permissions in AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" />

so in an asyncTask Kotlin class, we treat the creation of the file

    import android.os.AsyncTask
    import android.os.Environment
    import android.util.Log
    import java.io.*
    class WriteFile: AsyncTask<String, Int, String>() {
        private val mFolder = "/MainFolder"
        lateinit var folder: File
        internal var writeThis = "string to cacheApp.txt"
        internal var cacheApptxt = "cacheApp.txt"
        override fun doInBackground(vararg writethis: String): String? {
            val received = writethis[0]
            if(received.isNotEmpty()){
                writeThis = received
            }
            folder = File(Environment.getExternalStorageDirectory(),"$mFolder/")
            if(!folder.exists()){
                folder.mkdir()
                val readME = File(folder, cacheApptxt)
                val file = File(readME.path)
                val out: BufferedWriter
                try {
                    out = BufferedWriter(FileWriter(file, true), 1024)
                    out.write(writeThis)
                    out.newLine()
                    out.close()
                    Log.d("Output_Success", folder.path)
                } catch (e: Exception) {
                    Log.d("Output_Exception", "$e")
                }
            }
            return folder.path

    }

        override fun onPostExecute(result: String) {
            super.onPostExecute(result)

            if(result.isNotEmpty()){
                //implement an interface or do something
                Log.d("onPostExecuteSuccess", result)
            }else{
                Log.d("onPostExecuteFailure", result)
            }
        }

    }

Of course if you are using Android above Api 23, you must handle the request to allow writing to device memory. Something like this

    import android.Manifest
    import android.content.Context
    import android.content.pm.PackageManager
    import android.os.Build
    import androidx.appcompat.app.AppCompatActivity
    import androidx.core.app.ActivityCompat
    import androidx.core.content.ContextCompat

    class ReadandWrite {
        private val mREAD = 9
        private val mWRITE = 10
        private var readAndWrite: Boolean = false
        fun readAndwriteStorage(ctx: Context, atividade: AppCompatActivity): Boolean {
            if (Build.VERSION.SDK_INT < 23) {
                readAndWrite = true
            } else {
                val mRead = ContextCompat.checkSelfPermission(ctx, Manifest.permission.READ_EXTERNAL_STORAGE)
                val mWrite = ContextCompat.checkSelfPermission(ctx, Manifest.permission.WRITE_EXTERNAL_STORAGE)

                if (mRead != PackageManager.PERMISSION_GRANTED) {
                    ActivityCompat.requestPermissions(atividade, arrayOf(Manifest.permission.READ_EXTERNAL_STORAGE), mREAD)
                } else {
                    readAndWrite = true
                }

                if (mWrite != PackageManager.PERMISSION_GRANTED) {
                    ActivityCompat.requestPermissions(atividade, arrayOf(Manifest.permission.WRITE_EXTERNAL_STORAGE), mWRITE)
                } else {
                    readAndWrite = true
                }
            }
            return readAndWrite
        }
    }

then in an activity, execute the call.

  var pathToFileCreated = ""
    val anRW = ReadandWrite().readAndwriteStorage(this,this)
    if(anRW){
        pathToFileCreated =  WriteFile().execute("onTaskComplete").get()
        Log.d("pathToFileCreated",pathToFileCreated)
    }

If you have SQL Server 2012:

If your date parts are integers then you can use DATEFROMPARTS function.

SELECT DATENAME( dw, DATEFROMPARTS( @Year, @Month, @Day ) )

If your date parts are strings, then you can use the CONCAT function.

SELECT DATENAME( dw, CONVERT( date, CONCAT( @Day, '/' , @Month, '/', @Year ), 103 ) )

Swift 3 / Swift 4 Update:

let screenSize: CGRect = UIScreen.main.bounds
let myView = UIView(frame: CGRect(x: 0, y: 0, width: screenSize.width - 10, height: 10))
self.view.addSubview(myView)

Avoid using Xcode to rename files in a folder reference. If you rename a file using Xcode, it will be marked for commit. If you later delete it before the commit, you will end up with this error.

You are using ES6 Module syntax.

This means your environment (e.g. node.js) must support ES6 Module syntax.

NodeJS uses CommonJS Module syntax (module.exports) not ES6 module syntax (export keyword).

Solution:

• Use babel npm package to transpile your ES6 to a commonjs target

or

• Refactor with CommonJS syntax.

Examples of CommonJS syntax are (from flaviocopes.com/commonjs/):

• exports.uppercase = str => str.toUpperCase()
• exports.a = 1

char *s  does not have some memory allocated . You need to allocate it manually in your case . You can do it as follows
s = (char *)malloc(100) ;

This would not lead to segmentation fault error as you will not be refering to an unknown location anymore

In the bash shell, surround arithmetic expressions with $(( ... ))

$ echo $(( 7 / 3 ))

Although I think you are limited to integers.

Got this exception when maintaining very old application on Server 2003 using Asp classic on IIS6 with Oracle 9.2.0.1. The fix is by updating oracle to 9.2.0.6.

The multiline flag tells regex to match the pattern to each line as opposed to the entire string for your purposes a wild card will suffice.

The wizard likely created the package as a file. Do a search on your system for files with an extension of .dtsx. This is the actual "SSIS Package" file.

As for loading it in Management Studio, you don't actually view it through there. If you have SQL Server 2005 loaded on your machine, look in the program group. You should find an application with the same icon as Visual Studio called "SQL Server Business Intelligence Development Studio". It's basically a stripped down version of VS 2005 which allows you to create SSIS packages.

Create a blank solution and add your .dtsx file to that to edit/view it.

Apparently it's possible to do this in jQuery:

$("#tabs").css("cssText", "height: 650px !important;");

Src: http://bugs.jquery.com/ticket/2066

for (int i = 0; i < 6; i++)
{
    test.ColumnDefinitions.Add(new ColumnDefinition());

    Label t1 = new Label();
    t1.Content = "Test" + i;

    Grid.SetColumn(t1, i);
    Grid.SetRow(t1, 0);
    test.Children.Add(t1);
}

To handle the situation in which there is no wiring, beans are available with @Autowired required attribute set to false.

But when using @Inject, the Provider interface works with the bean which means that the bean is not injected directly but with the Provider.

You can use PageMethods.Your C# method Name in order to access C# methods or VB.NET methods into JavaScript.

One option is to store them as optional function variables:

struct MyAwesomeStruct {
    var myWonderfulFunction : Optional<(Int) -> Int> = nil
}

let squareCalculator =
    MyAwesomeStruct(myWonderfulFunction: { input in return input * input })
let thisShouldBeFour = squareCalculator.myWonderfulFunction!(2)

I am pretty sure this is a duplicate. Anyway, have a look at the following piece of code

x <- seq(5, 15, length=1000)
y <- dnorm(x, mean=10, sd=3)
plot(x, y, type="l", lwd=1)

I'm sure you can work the rest out yourself, for the title you might want to look for something called main= and y-axis labels are also up to you.

If you want to see more of the tails of the distribution, why don't you try playing with the seq(5, 15, ) section? Finally, if you want to know more about what dnorm is doing I suggest you look here

it is working when adding :

select { width:115% }

Be careful with the slash, change "\" for "/" , like this: adb.exe push SuperSU-v2.79-20161205182033.apk /storage

Try something like

SELECT
    CASE var
        WHEN xyz THEN col1
        WHEN zyx THEN col2
        ELSE col7
    END AS col1,
    ...

In other words, use a conditional expression to select the value, then rename the column.

Alternately, you could build up some sort of dynamic SQL hack to share the query tail; I've done this with iBatis before.

imports are used to import supporting modules like FormsModule, RouterModule, CommonModule, or any other custom-made feature module.

declarations are used to declare components, directives, pipes that belong to the current module. Everyone inside declarations knows each other. For example, if we have a component, say UsernameComponent, which displays a list of the usernames and we also have a pipe, say toupperPipe, which transforms a string to an uppercase letter string. Now If we want to show usernames in uppercase letters in our UsernameComponent then we can use the toupperPipe which we had created before but the question is how UsernameComponent knows that the toupperPipe exists and how it can access and use that. Here come the declarations, we can declare UsernameComponent and toupperPipe.

Providers are used for injecting the services required by components, directives, pipes in the module.

You can use the controls PointToScreen method to get the absolute position with respect to the screen.

You can do the Forms PointToScreen method, and with basic math, get the control's position.

The :active pseudo-class is not the same as adding a class to style the element.

The :active CSS pseudo-class represents an element (such as a button) that is being activated by the user. When using a mouse, "activation" typically starts when the mouse button is pressed down and ends when it is released.

What we are looking for is a class, such as .active, which we can use to style the navigation item.

For a clearer example of the difference between :active and .active see the following snippet:

li:active {_x000D_
  background-color: #35495E;_x000D_
}_x000D_
_x000D_
li.active {_x000D_
  background-color: #41B883;_x000D_
}

<ul>_x000D_
  <li>:active (pseudo-class) - Click me!</li>_x000D_
  <li class="active">.active (class)</li>_x000D_
</ul>

Vue-Router

vue-router automatically applies two active classes, .router-link-active and .router-link-exact-active, to the <router-link> component.

router-link-active

This class is applied automatically to the <router-link> component when its target route is matched.

The way this works is by using an inclusive match behavior. For example, <router-link to="/foo"> will get this class applied as long as the current path starts with /foo/ or is /foo.

So, if we had <router-link to="/foo"> and <router-link to="/foo/bar">, both components would get the router-link-active class when the path is /foo/bar.

router-link-exact-active

This class is applied automatically to the <router-link> component when its target route is an exact match. Take into consideration that both classes, router-link-active and router-link-exact-active, will be applied to the component in this case.

Using the same example, if we had <router-link to="/foo"> and <router-link to="/foo/bar">, the router-link-exact-activeclass would only be applied to <router-link to="/foo/bar"> when the path is /foo/bar.

The exact prop

Lets say we have <router-link to="/">, what will happen is that this component will be active for every route. This may not be something that we want, so we can use the exact prop like so: <router-link to="/" exact>. Now the component will only get the active class applied when it is an exact match at /.

CSS

We can use these classes to style our element, like so:

 nav li:hover,
 nav li.router-link-active,
 nav li.router-link-exact-active {
   background-color: indianred;
   cursor: pointer;
 }

The <router-link> tag was changed using the tag prop, <router-link tag="li" />.

Change default classes globally

If we wish to change the default classes provided by vue-router globally, we can do so by passing some options to the vue-router instance like so:

const router = new VueRouter({
  routes,
  linkActiveClass: "active",
  linkExactActiveClass: "exact-active",
})

Change default classes per component instance (<router-link>)

If instead we want to change the default classes per <router-link> and not globally, we can do so by using the active-class and exact-active-class attributes like so:

<router-link to="/foo" active-class="active">foo</router-link>

<router-link to="/bar" exact-active-class="exact-active">bar</router-link>

v-slot API

Vue Router 3.1.0+ offers low level customization through a scoped slot. This comes handy when we wish to style the wrapper element, like a list element <li>, but still keep the navigation logic in the anchor element <a>.

<router-link
  to="/foo"
  v-slot="{ href, route, navigate, isActive, isExactActive }"
>
  <li
    :class="[isActive && 'router-link-active', isExactActive && 'router-link-exact-active']"
  >
    <a :href="href" @click="navigate">{{ route.fullPath }}</a>
  </li>
</router-link>

Swift 4

You can somewhat think about it as array of object vs. array of references.

• [SKSpriteNode] must contain actual objects
• [SKSpriteNode?] can contain either references to objects, or nil

Examples

1. Creating an array with 64 default SKSpriteNode:

   var sprites = [SKSpriteNode](repeatElement(SKSpriteNode(texture: nil),
                                              count: 64))
   

2. Creating an array with 64 empty slots (a.k.a optionals):

   var optionalSprites = [SKSpriteNode?](repeatElement(nil,
                                         count: 64))
   

3. Converting an array of optionals into an array of objects (collapsing [SKSpriteNode?] into [SKSpriteNode]):

   let flatSprites = optionalSprites.flatMap { $0 }
   

   The count of the resulting flatSprites depends on the count of objects in optionalSprites: empty optionals will be ignored, i.e. skipped.

I believe you are looking for the outline CSS property (in conjunction with active and hover psuedo attributes):

/* turn it off completely */
select:active, select:hover {
  outline: none
}

/* make it red instead (with with same width and style) */
select:active, select:hover {
  outline-color: red
}

Full details of outline, outline-color, outline-style, and outline-width https://developer.mozilla.org/en-US/docs/Web/CSS/outline

$newstr = preg_replace('/[^a-zA-Z0-9\']/', '_', "There wouldn't be any");
$newstr = str_replace("'", '', $newstr);

I put them on two separate lines to make the code a little more clear.

Note: If you're looking for Unicode support, see Filip's answer below. It will match all characters that register as letters in addition to A-z.

What's a "block scheme"?

If I were drawing it, I might draw a box with "for each x in y" written in it.

If you're drawing a flowchart, there's always a loop with a decision box.

Nassi-Schneiderman diagrams have a loop construct you could use.

According to the fine manual, createConnection() can be used to connect to multiple databases.

However, you need to create separate models for each connection/database:

var conn      = mongoose.createConnection('mongodb://localhost/testA');
var conn2     = mongoose.createConnection('mongodb://localhost/testB');

// stored in 'testA' database
var ModelA    = conn.model('Model', new mongoose.Schema({
  title : { type : String, default : 'model in testA database' }
}));

// stored in 'testB' database
var ModelB    = conn2.model('Model', new mongoose.Schema({
  title : { type : String, default : 'model in testB database' }
}));

I'm pretty sure that you can share the schema between them, but you have to check to make sure.

android:scaleType ="centerInside" --> this line use to center an image,, but you need to keep height and width of an image as wrap_context

 <ImageView
            android:id ="@+id/imageView6"
            android:layout_width ="wrap_content"
            android:layout_height ="wrap_content"
            android:scaleType ="centerInside"
            android:layout_marginTop ="20dp"
            app:srcCompat ="@drawable/myimage" />

The method

Connect to port 80 on the host and send it

HEAD / HTTP/1.0

This needs to be followed by carriage-return + line-feed twice

You'll get back something like this

HTTP/1.1 200 OK
Date: Fri, 03 Oct 2008 12:39:43 GMT
Server: Apache/2.2.9 (Ubuntu) DAV/2 SVN/1.5.0 PHP/5.2.6-1ubuntu4 with Suhosin-Patch mod_perl/2.0.4 Perl/v5.10.0
Last-Modified: Thu, 02 Aug 2007 20:50:09 GMT
ETag: "438118-197-436bd96872240"
Accept-Ranges: bytes
Content-Length: 407
Connection: close
Content-Type: text/html; charset=UTF-8

You can then extract the apache version from the Server: header

Typical tools you can use

You could use the HEAD utility which comes with a full install of Perl's LWP library, e.g.

HEAD http://your.webserver.com/

Or, use the curl utility, e.g.

 curl --head http://your.webserver.com/

You could also use a browser extension which lets you view server headers, such as Live HTTP Headers or Firebug for Firefox, or Fiddler for IE

Stuck with Windows?

Finally. if you're on Windows, and have nothing else at your disposal, open a command prompt (Start Menu->Run, type "cmd" and press return), and then type this

telnet your.webserver.com 80

Then type (carefully, your characters won't be echoed back)

HEAD / HTTP/1.0

Press return twice and you'll see the server headers.

Other methods

As mentioned by cfeduke and Veynom, the server may be set to return limited information in the Server: header. Try and upload a PHP script to your host with this in it

<?php phpinfo() ?>

Request the page with a web browser and you should see the Apache version reported there.

You could also try and use PHPShell to have a poke around, try a command like

/usr/sbin/apache2 -V

This should work.

<div my-method='theMethodToBeCalled'></div>

app.directive("myMethod",function($parse) {
  restrict:'A',

Create a user first. You must do this as user postgres. Because the postgres system account has no password assigned, you can either set a password first, or you go like this:

sudo /bin/bash
# you should be root now  
su postgres
# you are postgres now
createuser --interactive

and the programm will prompt you.

I've used IP*Works SSH and it is great. Easy to setup and use. Plus, their support is top-notch when you run into questions or problems.

There are multiple options:

txtBox.Focus();
txtBox.SelectionStart = txtBox.Text.Length;

OR

txtBox.Focus();
txtBox.CaretIndex = txtBox.Text.Length;

OR

txtBox.Focus();
txtBox.Select(txtBox.Text.Length, 0);

You can use String.split (read more here) instead of charAt, you will get good results. If you want to use charAt for some reason then try trimming the string before you count the words that way you won't have the extra space and an extra word

Try this

<include
            android:id="@+id/OnlineOffline"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            layout="@layout/YourLayoutName" />

If you're storing the object as type object, you need to use reflection. This is true of any object type, anonymous or otherwise. On an object o, you can get its type:

Type t = o.GetType();

Then from that you look up a property:

PropertyInfo p = t.GetProperty("Foo");

Then from that you can get a value:

object v = p.GetValue(o, null);

This answer is long overdue for an update for C# 4:

dynamic d = o;
object v = d.Foo;

And now another alternative in C# 6:

object v = o?.GetType().GetProperty("Foo")?.GetValue(o, null);

Note that by using ?. we cause the resulting v to be null in three different situations!

1. o is null, so there is no object at all
2. o is non-null but doesn't have a property Foo
3. o has a property Foo but its real value happens to be null.

So this is not equivalent to the earlier examples, but may make sense if you want to treat all three cases the same.

Another option is to use DecimalFormat to format your numeric String. Here is one other way to do the job without having to use String.format if you are stuck in the pre 1.5 world:

static String intToString(int num, int digits) {
    assert digits > 0 : "Invalid number of digits";

    // create variable length array of zeros
    char[] zeros = new char[digits];
    Arrays.fill(zeros, '0');
    // format number as String
    DecimalFormat df = new DecimalFormat(String.valueOf(zeros));

    return df.format(num);
}

var x= {}
var y= {x:'hi'}
console.log(Object.keys(x).length===0)
console.log(Object.keys(y).length===0)

true
false

For ASCII characters in the range [ -~] on Python 2:

>>> import binascii
>>> bin(int(binascii.hexlify('hello'), 16))
'0b110100001100101011011000110110001101111'

In reverse:

>>> n = int('0b110100001100101011011000110110001101111', 2)
>>> binascii.unhexlify('%x' % n)
'hello'

In Python 3.2+:

>>> bin(int.from_bytes('hello'.encode(), 'big'))
'0b110100001100101011011000110110001101111'

In reverse:

>>> n = int('0b110100001100101011011000110110001101111', 2)
>>> n.to_bytes((n.bit_length() + 7) // 8, 'big').decode()
'hello'

To support all Unicode characters in Python 3:

def text_to_bits(text, encoding='utf-8', errors='surrogatepass'):
    bits = bin(int.from_bytes(text.encode(encoding, errors), 'big'))[2:]
    return bits.zfill(8 * ((len(bits) + 7) // 8))

def text_from_bits(bits, encoding='utf-8', errors='surrogatepass'):
    n = int(bits, 2)
    return n.to_bytes((n.bit_length() + 7) // 8, 'big').decode(encoding, errors) or '\0'

Here's single-source Python 2/3 compatible version:

import binascii

def text_to_bits(text, encoding='utf-8', errors='surrogatepass'):
    bits = bin(int(binascii.hexlify(text.encode(encoding, errors)), 16))[2:]
    return bits.zfill(8 * ((len(bits) + 7) // 8))

def text_from_bits(bits, encoding='utf-8', errors='surrogatepass'):
    n = int(bits, 2)
    return int2bytes(n).decode(encoding, errors)

def int2bytes(i):
    hex_string = '%x' % i
    n = len(hex_string)
    return binascii.unhexlify(hex_string.zfill(n + (n & 1)))

Example

>>> text_to_bits('hello')
'0110100001100101011011000110110001101111'
>>> text_from_bits('110100001100101011011000110110001101111') == u'hello'
True

Your Delivery class is internal (the default visibility for classes), however the property (and presumably the containing class) are public, so the property is more accessible than the Delivery class. You need to either make Delivery public, or restrict the visibility of the thelivery property.

When you're binding to variables, you need to use the brackets. Also, you use the hashtag when you want to get references to elements in your html, not for declaring variables inside of templates like that.

Edit: Thanks to Christopher Moore: Angular exposes the following local variables:

• index
• first
• last
• even
• odd

My advice would be this:

/garages
  Returns list of garages (think JSON array here)
/garages/yyy
  Returns specific garage
/garage/yyy/cars
  Returns list of cars in garage
/garages/cars
  Returns list of all cars in all garages (may not be practical of course)
/cars
  Returns list of all cars
/cars/xxx
  Returns specific car
/cars/colors
  Returns lists of all posible colors for cars
/cars/colors/red,blue,green
  Returns list of cars of the specific colors (yes commas are allowed :) )

Edit:

/cars/colors/red,blue,green/doors/2
  Returns list of all red,blue, and green cars with 2 doors.
/cars/type/hatchback,coupe/colors/red,blue,green/
  Same idea as the above but a lil more intuitive.
/cars/colors/red,blue,green/doors/two-door,four-door
  All cars that are red, blue, green and have either two or four doors.

Hopefully that gives you the idea. Essentially your Rest API should be easily discoverable and should enable you to browse through your data. Another advantage with using URLs and not query strings is that you are able to take advantage of the native caching mechanisms that exist on the web server for HTTP traffic.

Here's a link to a page describing the evils of query strings in REST: http://web.archive.org/web/20070815111413/http://rest.blueoxen.net/cgi-bin/wiki.pl?QueryStringsConsideredHarmful

I used Google's cache because the normal page wasn't working for me here's that link as well: http://rest.blueoxen.net/cgi-bin/wiki.pl?QueryStringsConsideredHarmful

You can use the asXML method as:

<?php

// string to SimpleXMLElement
$xml = new SimpleXMLElement($string);

// make any changes.
....

// convert the SimpleXMLElement back to string.
$newString = $xml->asXML();
?>

You have to initialise the object (create the object itself) in order to be able to call its methods otherwise you would get a NullPointerException.

WordList words = new WordList();

A bit late to this question, but I created a class with all the handy methods needed to create a fully functional time trial in C#. Rather than your application config, I write the expiry time to the Windows Application Data path, and that will also remain persistent even after the program has closed (it's also tricky to find the path for the average user).

Fully documented and simple to use, I hope someone finds it useful!

public class TimeTrialManager
{
    private long expiryTime=0;
    private string softwareName = "";
    private string userPath="";
    private bool useSeconds = false;

    public TimeTrialManager(string softwareName) {
        this.softwareName = softwareName;
        // Create folder in Windows Application Data folder for persistence:
        userPath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData).ToString() + "\\" + softwareName + "_prefs\\";
        if (!Directory.Exists(userPath)) Directory.CreateDirectory(Path.GetDirectoryName(userPath));
        userPath += "expiryinfo.txt";
    }

    // Use this method to check if the expiry has already been created. If
    // it has, you don't need to call the setExpiryDate() method ever again.
    public bool expiryHasBeenStored(){
        return File.Exists(userPath);
    }

    // Use this to set expiry as the number of days from the current time.
    // This should be called just once in the program's lifetime for that user.
    public void setExpiryDate(double days)  {
        DateTime time = DateTime.Now.AddDays(days);
        expiryTime = time.ToFileTimeUtc();
        storeExpiry(expiryTime.ToString() );
        useSeconds = false;
    }

    // Like above, but set the number of seconds. This should be just used for testing
    // as no sensible time trial would allow the user seconds to test the trial out:
    public void setExpiryTime(double seconds)   {
        DateTime time = DateTime.Now.AddSeconds(seconds);
        expiryTime = time.ToFileTimeUtc();
        storeExpiry(expiryTime.ToString());
        useSeconds = true;
    }

    // Check for this in a background timer or whenever else you wish to check if the time has run out
    public bool trialHasExpired()   {
        if(!File.Exists(userPath)) return false;
        if (expiryTime == 0)    expiryTime = Convert.ToInt64(File.ReadAllText(userPath));
        if (DateTime.Now.ToFileTimeUtc() >= expiryTime) return true; else return false;
    }

    // This method is optional and isn't required to use the core functionality of the class
    // Perhaps use it to tell the user how long he has left to trial the software
    public string expiryAsHumanReadableString(bool remaining=false) {
        DateTime dt = new DateTime();
        dt = DateTime.FromFileTimeUtc(expiryTime);
        if (remaining == false) return dt.ToShortDateString() + " " + dt.ToLongTimeString();
        else {
            if (useSeconds) return dt.Subtract(DateTime.Now).TotalSeconds.ToString();
            else return (dt.Subtract(DateTime.Now).TotalDays ).ToString();
        }
    }

    // This method is private to the class, so no need to worry about it
    private void storeExpiry(string value)  {
        try { File.WriteAllText(userPath, value); }
        catch (Exception ex) { MessageBox.Show(ex.Message); }
    }

}

Here is a typical usage of the above class. Couldn't be simpler!

TimeTrialManager ttm;
private void Form1_Load(object sender, EventArgs e)
{
    ttm = new TimeTrialManager("TestTime");
    if (!ttm.expiryHasBeenStored()) ttm.setExpiryDate(30); // Expires in 30 days time
}

private void timer1_Tick(object sender, EventArgs e)
{
    if (ttm.trialHasExpired()) { MessageBox.Show("Trial over! :("); Environment.Exit(0); }
}

You can use date_parse_from_format() function ...

Check this link..you will get clear idea

Seeing as everyone else has already listed most of the other ways to say not equal I will just add:

if not (1) == (1): # This will eval true then false
    # (ie: 1 == 1 is true but the opposite(not) is false)
    print "the world is ending" # This will only run on a if true
elif (1+1) != (2): #second if
    print "the world is ending"
    # This will only run if the first if is false and the second if is true
else: # this will only run if the if both if's are false
    print "you are good for another day"

in this case it is simple switching the check of positive == (true) to negative and vise versa...

You can do this to only monitor own properties of the object:

var arr = [];

for (var key in p) {
    if (p.hasOwnProperty(key)) {
        arr.push(p[key]);
    }
}

I had a similar use case where I wanted to test a Spring Boot configured repository in isolation (in my case without Spring Security autoconfiguration which was failing my test). @SpringApplicationConfiguration uses SpringApplicationContextLoader and that has a JavaDoc stating

Can be used to test non-web features (like a repository layer) or start an fully-configured embedded servlet container.

However, like yourself, I could not work out how you are meant to configure the test to only test the repository layer using the main configuration entry point i.e. using your approach of @SpringApplicationConfiguration(classes = Application.class).

My solution was to create a completely new application context exclusive for testing. So in src/test/java I have two files in a sub-package called repo

1. RepoIntegrationTest.java
2. TestRepoConfig.java

where RepoIntegrationTest.java has

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = TestRepoConfig.class)
public class RepoIntegrationTest {

and TestRepoConfig.java has

@SpringBootApplication(exclude = SecurityAutoConfiguration.class)
public class TestRepoConfig {

It got me out of trouble but it would be really useful if anyone from the Spring Boot team could provide an alternative recommended solution

select substring(your_field, CHARINDEX(';',your_field)+1 ,CHARINDEX('[',your_field)-CHARINDEX(';',your_field)-1) from your_table

Can't get the others to work. I believe you just want what is in between ';' and '[' in all cases regardless of how long the string in between is. After specifying the field in the substring function, the second argument is the starting location of what you will extract. That is, where the ';' is + 1 (fourth position - the c), because you don't want to include ';'. The next argument takes the location of the '[' (position 14) and subtracts the location of the spot after the ';' (fourth position - this is why I now subtract 1 in the query). This basically says substring(field,location I want substring to begin, how long I want substring to be). I've used this same function in other cases. If some of the fields don't have ';' and '[', you'll want to filter those out in the "where" clause, but that's a little different than the question. If your ';' was say... ';;;', you would use 3 instead of 1 in the example. Hope this helps!

$date = new DateTime($_POST['date']);
$endDate = date_add(new DateTime($_POST['date']),date_interval_create_from_date_string("7 days"));

while ($date <= $endDate) {
    print date_format($date,'d-m-Y')." AND END DATE IS : ".date_format($endDate,'d-m-Y')."\n";
    date_add($date,date_interval_create_from_date_string("1 days"));
}

You can iterate like this also, The $_POST['date'] can be dent from your app or website Instead of $_POST['date'] you can also place your string here "21-12-2019". Both will work.

Jquery 3.0 has some breaking changes that remove certain methods due to conflicts. Your error is most likely due to one of these changes such as the removal of the .load() event.

Read more in the jQuery Core 3.0 Upgrade Guide

To fix this you either need to rewrite the code to be compatible with Jquery 3.0 or else you can use the JQuery Migrate plugin which restores the deprecated and/or removed APIs and behaviours.

ser.read(64) should be ser.read(size=64); ser.read uses keyword arguments, not positional.

Also, you're reading from the port twice; what you probably want to do is this:

i=0
for modem in PortList:
    for port in modem:
        try:
            ser = serial.Serial(port, 9600, timeout=1)
            ser.close()
            ser.open()
            ser.write("ati")
            time.sleep(3)
            read_val = ser.read(size=64)
            print read_val
            if read_val is not '':
                print port
        except serial.SerialException:
            continue
        i+=1

Found solution on css-tricks

const element = document.getElementById('img')

element.classList.remove('classname'); // reset animation
void element.offsetWidth; // trigger reflow
element.classList.add('classname'); // start animation

If you only need precision to the second, you can use the builtin $SECONDS variable, which counts the number of seconds that the shell has been running.

while true; do
    start=$SECONDS
    some_long_running_command
    duration=$(( SECONDS - start ))
    echo "This run took $duration seconds"
    if some_condition; then break; fi
done

Both will have a key of 0, and that method of combining the arrays will collapse duplicates. Try using array_merge() instead.

$arr1 = array('foo'); // Same as array(0 => 'foo')
$arr2 = array('bar'); // Same as array(0 => 'bar')

// Will contain array('foo', 'bar');
$combined = array_merge($arr1, $arr2);

If the elements in your array used different keys, the + operator would be more appropriate.

$arr1 = array('one' => 'foo');
$arr2 = array('two' => 'bar');

// Will contain array('one' => 'foo', 'two' => 'bar');
$combined = $arr1 + $arr2;

Edit: Added a code snippet to clarify

I'd use absolute positioning:

#play_button {
    position:absolute;
transition: .5s ease;
    left: 202px;
    top: 198px;

}

Which version of .NET are you using? If it's .NET 3.5, I'd just call ToArray() and be done with it.

If you only have a non-generic IEnumerable, do something like this:

IEnumerable query = ...;
MyEntityType[] array = query.Cast<MyEntityType>().ToArray();

If you don't know the type within that method but the method's callers do know it, make the method generic and try this:

public static void T[] PerformQuery<T>()
{
    IEnumerable query = ...;
    T[] array = query.Cast<T>().ToArray();
    return array;
}

Angular library uses document.documentMode to identify IE . It holds major version number for IE, or NaN/undefined if User Agent is not IE.

/**
* documentMode is an IE-only property
* http://msdn.microsoft.com/en-us/library/ie/cc196988(v=vs.85).aspx
*/
var msie = document.documentMode;

https://github.com/angular/angular.js/blob/v1.5.0/src/Angular.js#L167-L171

Example with $document (angular wrapper for window.document)

// var msie = document.documentMode;
var msie = $document[0].documentMode;
// if is IE (documentMode contains IE version)
if (msie) {
  // IE logic here

  if (msie === 9) {
    // IE 9 logic here

  }
}

As kmcamara discovered, this is exactly the kind of problem that VLOOKUP is intended to solve, and using vlookup is arguably the simplest of the alternative ways to get the job done.

In addition to the three parameters for lookup_value, table_range to be searched, and the column_index for return values, VLOOKUP takes an optional fourth argument that the Excel documentation calls the "range_lookup".

Expanding on deathApril's explanation, if this argument is set to TRUE (or 1) or omitted, the table range must be sorted in ascending order of the values in the first column of the range for the function to return what would typically be understood to be the "correct" value. Under this default behavior, the function will return a value based upon an exact match, if one is found, or an approximate match if an exact match is not found.

If the match is approximate, the value that is returned by the function will be based on the next largest value that is less than the lookup_value. For example, if "12AT8003" were missing from the table in Sheet 1, the lookup formulas for that value in Sheet 2 would return '2', since "12AT8002" is the largest value in the lookup column of the table range that is less than "12AT8003". (VLOOKUP's default behavior makes perfect sense if, for example, the goal is to look up rates in a tax table.)

However, if the fourth argument is set to FALSE (or 0), VLOOKUP returns a looked-up value only if there is an exact match, and an error value of #N/A if there is not. It is now the usual practice to wrap an exact VLOOKUP in an IFERROR function in order to catch the no-match gracefully. Prior to the introduction of IFERROR, no matches were checked with an IF function using the VLOOKUP formula once to check whether there was a match, and once to return the actual match value.

Though initially harder to master, deusxmach1na's proposed solution is a variation on a powerful set of alternatives to VLOOKUP that can be used to return values for a column or list to the left of the lookup column, expanded to handle cases where an exact match on more than one criterion is needed, or modified to incorporate OR as well as AND match conditions among multiple criteria.

Repeating kcamara's chosen solution, the VLOOKUP formula for this problem would be:

   =VLOOKUP(A1,Sheet1!A$1:B$600,2,FALSE)

Try to embed a table element.

<div>_x000D_
  <table style='width:200px; height:100px;'>_x000D_
    <td style='vertical-align:middle;'>_x000D_
      copenhagen_x000D_
    </td>_x000D_
  </table>_x000D_
</div>

REPEAT
    ...
UNTIL cond

Is equivalent to

while True:
    ...
    if cond:
        break

Using lambda expression

db.Categories    
  .GroupJoin(db.Products,
      Category => Category.CategoryId,
      Product => Product.CategoryId,
      (x, y) => new { Category = x, Products = y })
  .SelectMany(
      xy => xy.Products.DefaultIfEmpty(),
      (x, y) => new { Category = x.Category, Product = y })
  .Select(s => new
  {
      CategoryName = s.Category.Name,     
      ProductName = s.Product.Name   
  });

Easier way for me is to switch to R1C1 notation and just use R[-1]C1 and switch back when done.

void numel(int array1[100][100])
{
    int count=0;
    for(int i=0;i<100;i++)
    {
        for(int j=0;j<100;j++)
        {
            if(array1[i][j]!='\0') 
            {
                count++;
                //printf("\n%d-%d",array1[i][j],count);
            }
            else 
                break;
        }
    }
    printf("Number of elements=%d",count);
}
int main()
{   
    int r,arr[100][100]={0},c;
    printf("Enter the no. of rows: ");
    scanf("%d",&r);
    printf("\nEnter the no. of columns: ");
    scanf("%d",&c);
    printf("\nEnter the elements: ");
    for(int i=0;i<r;i++)
    {
        for(int j=0;j<c;j++)
        {
            scanf("%d",&arr[i][j]);
        }
    }
    numel(arr);
}

This shows the exact number of elements in matrix irrespective of the array size you mentioned while initilasing(IF that's what you meant)

Using AWS Management Console:

Difference is clear In builder pattern, builder will create specific type of object for you. You have to tell what builder has to build. In factory pattern , using abstract class you are directly building the specific object.

Here builder class acts as mediator between main class and specific type classes. More abstraction.

You would need to create a generic class named MyProp. Then, you will need to add implicit or explicit cast operators so you can get and set the value as if it were the type specified in the generic type parameter. These cast operators can do the extra work that you need.

Did not have this problem when I built and ran on my own device. Only had this problem with simulators. I just simply restarted my computer and ran it. It worked.

You have the following options on Windows command line:

net use [DeviceName [/home[{Password | *}] [/delete:{yes | no}]]

Try like:

net use H: /delete /y

Use the property TextWrapping of the TextBlock element:

<TextBlock Text="StackOverflow Forum"
           Width="100"
           TextWrapping="WrapWithOverflow"/>

This is an old question but I just had the same issue (with PHP7) and the solution was, in the end, pretty simple. Uncommenting the line in php.ini as per the other answers wasn't quite enough though. I needed to change it from:

;extension=php_openssl.dll

to:

extension=ext/php_openssl.dll

Note the ext prefix. The dll already existed but was in a subfolder. After changing the config the composer installer was happy.

In react native, I had the error not show maps and close app, run adb logcat and show error within console:

java.lang.NoClassDefFoundError:failed resolution of :Lorg/apache/http/ProtocolVersion

fix it by adding within androidManifest.xml

<uses-library
  android:name="org.apache.http.legacy"
  android:required="false" />

You are using <input name='C[]' in your HTML. This creates an array in PHP when the form is sent.

You are using echo $_POST['C']; to echo that array - this will not work, but instead emit that notice and the word "Array".

Depending on what you did with the rest of the code, you should probably use echo $_POST['C'][0];

you can define a custom ScrollView class, & add an interface be called when scrolling like this:

public class ScrollChangeListenerScrollView extends HorizontalScrollView {


private MyScrollListener mMyScrollListener;

public ScrollChangeListenerScrollView(Context context) {
    super(context);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}


public void setOnMyScrollListener(MyScrollListener myScrollListener){
    this.mMyScrollListener = myScrollListener;
}


@Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
    super.onScrollChanged(l, t, oldl, oldt);
    if(mMyScrollListener!=null){
        mMyScrollListener.onScrollChange(this,l,t,oldl,oldt);
    }

}

public interface MyScrollListener {
    void onScrollChange(View view,int scrollX,int scrollY,int oldScrollX, int oldScrollY);
}

}

Spring is a collection of best-practise API patterns, you can write up a shopping list of them as long as your arm. The way that the API is designed encourages you (but doesn't force you) to follow these patterns, and half the time you follow them without knowing you are doing so.

So I am having this issue and it seems that unless you are on Linux you will not be able to use HAXM. [EDIT: this is if you have an AMD chip (non intel) of course as that is the issue]

As stated on the Android Site;

Many modern CPUs provide extensions for running virtual machines (VMs) more efficiently. Taking advantage of these extensions with the Android emulator requires some additional configuration of your development system, but can significantly improve the execution speed. Before attempting to use this type of acceleration, you should first determine if your development system’s CPU supports one of the following virtualization extensions technologies:

Intel Virtualization Technology (VT, VT-x, vmx) extensions

> AMD Virtualization (AMD-V, SVM) extensions (only supported for Linux)

As others have mentioned Genymotion may be a solution.

Thanks, finally got an solution to not put utf8::encode all over code. To synthesize and complete for other cases, like write and read files in utf8 and also works with LoadFile of an YAML file in utf8

use utf8;
use open ':encoding(utf8)';
binmode(STDOUT, ":utf8");

open(FH, ">test.txt"); 
print FH "something éá";

use YAML qw(LoadFile Dump);
my $PUBS = LoadFile("cache.yaml");
my $f = "2917";
my $ref = $PUBS->{$f};
print "$f \"".$ref->{name}."\" ". $ref->{primary_uri}." ";

where cache.yaml is:

---
2917:
  id: 2917
  name: Semanário
  primary_uri: 2917.xml

Since you are using .NET you can use the SQL Server Management Objects

Dim server As New Microsoft.SqlServer.Management.Smo.Server("localhost")
For Each db As Database In server.Databases
    Console.WriteLine(db.Name)
Next

If you go with the solution by @qiao, perhaps you would want to remove the appended child since the tab remains open and subsequent clicks would add more elements to the DOM.

// Code by @qiao
var a = document.createElement('a')
a.href = 'http://www.google.com'
a.target = '_blank'
document.body.appendChild(a)
a.click()
// Added code
document.body.removeChild(a)

Maybe someone could post a comment to his post, because I cannot.

I finally figured it out doing this:

var $your-original-element = $('.your-original-element');
var data = $your-original-element.select2('data')[0]['text'];
alert(data);

if you also want the value:

var value = $your-original-element.select2('data')[0]['id'];
alert(value);

Can i suggest http://www.jqueryscript.net/form/Twitter-Like-Mentions-Auto-Suggesting-Plugin-with-jQuery-Bootstrap-Suggest.html, works more like the twitter post suggestion where it gives you a list of users or topics based on @ or # tags,

view demo here: http://www.jqueryscript.net/demo/Twitter-Like-Mentions-Auto-Suggesting-Plugin-with-jQuery-Bootstrap-Suggest/

in this one you can easily change the @ and # to anything you want

Do you have concurrency, i.e simultaneous users ? If you just run 1000 times the query straight, with just one thread, there will be almost no difference. Too easy for these engines :)

BUT I strongly suggest that you build a true load testing session, which means using an injector such as JMeter with 10, 20 or 50 users AT THE SAME TIME so you can really see a difference (try to embed this code inside a web page JMeter could query).

I just did it today on a single server (and a simple collection / table) and the results are quite interesting and surprising (MongoDb was really faster on writes & reads, compared to MyISAM engine and InnoDb engine).

This really should be part of your test : concurrency & MySQL engine. Then, data/schema design & application needs are of course huge requirements, beyond response times. Let me know when you get results, I'm also in need of inputs about this!

The line would be as shown below:

Dim x As Integer    
x = dgvName.Rows(yourRowIndex).Cells(yourColumnIndex).Value

protected void setMenuBackground() {
    getLayoutInflater().setFactory(new Factory() {
        @Override
        public View onCreateView (String name, Context context, AttributeSet attrs) {
            if (name.equalsIgnoreCase("com.android.internal.view.menu.IconMenuItemView")) {
                try {
                    // Ask our inflater to create the view
                    LayoutInflater f = getLayoutInflater();
                    final View view = f.createView(name, null, attrs);
                    // Kind of apply our own background
                    new Handler().post( new Runnable() {
                        public void run () {
                            view.setBackgroundResource(R.drawable.gray_gradient_background);
                        }
                    });
                    return view;
                }
                catch (InflateException e) {
                }
                catch (ClassNotFoundException e) {
                }
            }
            return null;
        }
    });
}

if(window.location.href.indexOf("?added-to-cart=555") >= 0)

It's window.location.href, not window.location.

Here's how I've managed to solve this. It works on the premise that using a time reference between activity transitions will most likely provide adequate evidence that an app has been "backgrounded" or not.

First, I've used an android.app.Application instance (let's call it MyApplication) which has a Timer, a TimerTask, a constant to represent the maximum number of milliseconds that the transition from one activity to another could reasonably take (I went with a value of 2s), and a boolean to indicate whether or not the app was "in the background":

public class MyApplication extends Application {

    private Timer mActivityTransitionTimer;
    private TimerTask mActivityTransitionTimerTask;
    public boolean wasInBackground;
    private final long MAX_ACTIVITY_TRANSITION_TIME_MS = 2000;
    ...

The application also provides two methods for starting and stopping the timer/task:

public void startActivityTransitionTimer() {
    this.mActivityTransitionTimer = new Timer();
    this.mActivityTransitionTimerTask = new TimerTask() {
        public void run() {
            MyApplication.this.wasInBackground = true;
        }
    };

    this.mActivityTransitionTimer.schedule(mActivityTransitionTimerTask,
                                           MAX_ACTIVITY_TRANSITION_TIME_MS);
}

public void stopActivityTransitionTimer() {
    if (this.mActivityTransitionTimerTask != null) {
        this.mActivityTransitionTimerTask.cancel();
    }

    if (this.mActivityTransitionTimer != null) {
        this.mActivityTransitionTimer.cancel();
    }

    this.wasInBackground = false;
}

The last piece of this solution is to add a call to each of these methods from the onResume() and onPause() events of all activities or, preferably, in a base Activity from which all of your concrete Activities inherit:

@Override
public void onResume()
{
    super.onResume();

    MyApplication myApp = (MyApplication)this.getApplication();
    if (myApp.wasInBackground)
    {
        //Do specific came-here-from-background code
    }

    myApp.stopActivityTransitionTimer();
}

@Override
public void onPause()
{
    super.onPause();
    ((MyApplication)this.getApplication()).startActivityTransitionTimer();
}

So in the case when the user is simply navigating between the activities of your app, the onPause() of the departing activity starts the timer, but almost immediately the new activity being entered cancels the timer before it can reach the max transition time. And so wasInBackground would be false.

On the other hand when an Activity comes to the foreground from the Launcher, device wake up, end phone call, etc., more than likely the timer task executed prior to this event, and thus wasInBackground was set to true.

I was looking to use the print statement to debug some dynamic sql as I imagin most of you are using print for simliar reasons.

I tried a few of the solutions listed and found that Kelsey's solution works with minor tweeks (@sql is my @script) n.b. LENGTH isn't a valid function:

--http://stackoverflow.com/questions/7850477/how-to-print-varcharmax-using-print-statement
--Kelsey
DECLARE @Counter INT
SET @Counter = 0
DECLARE @TotalPrints INT
SET @TotalPrints = (LEN(@sql) / 4000) + 1
WHILE @Counter < @TotalPrints 
BEGIN
    PRINT SUBSTRING(@sql, @Counter * 4000, 4000)
    SET @Counter = @Counter + 1
END
PRINT LEN(@sql)

This code does as commented add a new line into the output, but for debugging this isn't a problem for me.

Ben B's solution is perfect and is the most elegent, although for debugging is a lot of lines of code so I choose to use my slight modification of Kelsey's. It might be worth creating a system like stored procedure in msdb for Ben B's code which could be reused and called in one line?

Alfoks' code doesn't work unfortunately because that would have been easier.

Converting the String to JsonNode using ObjectMapper object :

ObjectMapper mapper = new ObjectMapper();

// For text string
JsonNode = mapper.readValue(mapper.writeValueAsString("Text-string"), JsonNode.class)

// For Array String
JsonNode = mapper.readValue("[\"Text-Array\"]"), JsonNode.class)

// For Json String 
String json = "{\"id\" : \"1\"}";
ObjectMapper mapper = new ObjectMapper();
JsonFactory factory = mapper.getFactory();
JsonParser jsonParser = factory.createParser(json);
JsonNode node = mapper.readTree(jsonParser);

The Content-Length header is a number denoting an the exact byte length of the HTTP body. The HTTP body starts immediately after the first empty line that is found after the start-line and headers.

Generally the Content-Length header is used for HTTP 1.1 so that the receiving party knows when the current response^* has finished, so the connection can be reused for another request.

_{^{* ...or request, in the case of request methods that have a body, such as POST, PUT or PATCH}}

Alternatively, Content-Length header can be omitted and a chunked Transfer-Encoding header can be used.

If both Content-Length and Transfer-Encoding headers are missing, then at the end of the response the connection must be closed.

The following resource is a guide that I found very useful when learning about HTTP:

HTTP Made Really Easy.

If you luckily had the same files opened on another editor (eg. Sublime Text) try a ctrl-z on those. It just saved me..

If you ever wondered how to do it using the new BDD style of Mockito:

willThrow(new Exception()).given(mockedObject).methodReturningVoid(...));

And for future reference one may need to throw exception and then do nothing:

willThrow(new Exception()).willDoNothing().given(mockedObject).methodReturningVoid(...));

For me, this is the best autofit and autoresize for table and its columns (use css !important ... only if you can't without)

.myclass table {
    table-layout: auto !important;
}

.myclass th, .myclass td, .myclass thead th, .myclass tbody td, .myclass tfoot td, .myclass tfoot th {
    width: auto !important;
}

Don't specify css width for table or for table columns. If table content is larger it will go over screen size to.

'Error Code: 1046'. 

This error shows that the table does not exist may sometimes be caused by having selected a different database and running a query referring to another table. The results indicates 'No database selected Select the default DB to be used by double-clicking its name in the SCHEMAS list in the sidebar'. Will solve the issue and it worked for me very well.

Aahh got it... I got it working :)

Thanks Christopher, your suggesion is correct.

But, finding "Default SMTP Virtual Server" was tricky ;)

Even if you use IIS7 to deploy your web site, you have to open IIS6 Manager to configure SMTP server (why?).

I configured SMTP server as follows to make things work:

1. Open IIS6 Manager using Control Panel --> Administrative Tools.
2. Open SMTP Virtual Server properties.
3. On General tab, Set IP address of the Web server instead of "All Unassigned".
4. In Access tab, click on Relay button, this will open Relay Restrictions dialog.
5. In relay computers list, add the loopback IP address i.e 127.0.0.1 and IP address of the Web server, so that they can pass/relay emails through the SMTP server.

How about just $(this).is("[name]")?

The [attr] syntax is the CSS selector for an element with an attribute attr, and .is() checks if the element it is called on matches the given CSS selector.

To preserve key order, instead of hash(str(dictionary)) or hash(json.dumps(dictionary)) I would prefer quick-and-dirty solution:

from pprint import pformat
h = hash(pformat(dictionary))

It will work even for types like DateTime and more that are not JSON serializable.

If I understood you right, you mean that if you have a function 'func', you want to check for each item in list if func(item) returns true; if you get true for all, then do something.

You can use 'all'.

For example: I want to get all prime numbers in range 0-10 in a list:

from math import sqrt
primes = [x for x in range(10) if x > 2 and all(x % i !=0 for i in range(2, int(sqrt(x)) + 1))]

Here is the simplest example that has the key lines of code:

import numpy as np 
import matplotlib.pyplot as plt

H = np.array([[1, 2, 3, 4],
          [5, 6, 7, 8],
          [9, 10, 11, 12],
          [13, 14, 15, 16]])

plt.imshow(H, interpolation='none')
plt.show()

The command build in pipeline is there to trigger other jobs in jenkins.

Example on github

The job must exist in Jenkins and can be parametrized. As for the branch, I guess you can read it from git

I would set up a shortcut, either to CMD or to the thing you want to run, then set the properties of the shortcut to require admin, and then run the shortcut from your batch file. I haven't tested to confirm it will respect the properties, but I think it's more elegant and doesn't require activating the Administrator account.

Also if you do it as a scheduled task (which can be set up from code) there is an option to run it elevated there.

Use:

create table new_table_name 
as
select column_name,[more columns] from Existed_table;

Example:

create table dept
as
select empno, ename from emp;

If the table already exists:

insert into new_tablename select columns_list from Existed_table;

You just need to display the div with id #menu as flex container like this:

#menu{
    width: 800px;
    display: flex;
    justify-content: space-between;
}

Honestly, I have difficulty implementing it because there's barely any tutorials I've searched that displays writing the keys into the files. The accepted answer was "fine". But for me I had to improve it so that both keys gets saved into two separate files. I've written a helper class so y'all just gotta copy and paste it. Hope this helps lol.

Id advice you to use a bit simplier method -

$.post('edit.php', {title: $('input[name="title"]').val() }, function(resp){
    alert(resp);
});

try this one, I just feels its syntax is simplier than the $.ajax's one...

list all your docker images:

docker images

list all existed docker containers:

docker ps -a

delete all the targeted containers, which is using the image that you want to delete:

docker rm <container-id>

delete the targeted image:

docker rmi <image-name:image-tag or image-id>

Just some additions to previous answers. There are aliases defined for Get-Content, for example if you are used to UNIX you might like cat, and there are also type and gc. So instead of

Get-Content -Path <Path> -Wait -Tail 10

you can write

# Print whole file and wait for appended lines and print them
cat <Path> -Wait
# Print last 10 lines and wait for appended lines and print them
cat <Path> -Tail 10 -Wait

try the following code

select * from TableA A 
inner join TableB B on A.Column=B.Column 
inner join TableC C on A.Column=C.Column

During these peak CPU times, what is the user load like? You say this is a web based application, so the culprits that come to mind is memory utilization issues. If you store a lot of stuff in the session, for instance, and the session count gets high enough, the app server will start thrashing about. This is also a case where the GC might make matters worse depending on the scheme you are using. More information about the app and the server configuration would be helpful in pointing towards more debugging ideas.

As Jeroen says there are scoping issues: if you set 'count' outside the loop, you can't modify it inside the loop.

You can defeat this behavior by using an object rather than a scalar for 'count':

{% set count = [1] %}

You can now manipulate count inside a forloop or even an %include%. Here's how I increment count (yes, it's kludgy but oh well):

{% if count.append(count.pop() + 1) %}{% endif %} {# increment count by 1 #}

Answer in 2019:

Only use WOFF2, or if you need legacy support, WOFF. Do not use any other format

(svg and eot are dead formats, ttf and otf are full system fonts, and should not be used for web purposes)

Original answer from 2012:

In short, font-face is very old, but only recently has been supported by more than IE.

• eot is needed for Internet Explorers that are older than IE9 - they invented the spec, but eot was a proprietary solution.

• ttf and otf are normal old fonts, so some people got annoyed that this meant anyone could download expensive-to-license fonts for free.

• Time passes, SVG 1.1 adds a "fonts" chapter that explains how to model a font purely using SVG markup, and people start to use it. More time passes and it turns out that they are absolutely terrible compared to just a normal font format, and SVG 2 wisely removes the entire chapter again.

• Then, woff gets invented by people with quite a bit of domain knowledge, which makes it possible to host fonts in a way that throws away bits that are critically important for system installation, but irrelevant for the web (making people worried about piracy happy) and allows for internal compression to better suit the needs of the web (making users and hosts happy). This becomes the preferred format.

• 2019 edit A few years later, woff2 gets drafted and accepted, which improves the compression, leading to even smaller files, along with the ability to load a single font "in parts" so that a font that supports 20 scripts can be stored as "chunks" on disk instead, with browsers automatically able to load the font "in parts" as needed, rather than needing to transfer the entire font up front, further improving the typesetting experience.

If you don't want to support IE 8 and lower, and iOS 4 and lower, and android 4.3 or earlier, then you can just use WOFF (and WOFF2, a more highly compressed WOFF, for the newest browsers that support it.)

@font-face {

Suggestions are (basically) based on the text in the current open file and any snippets or completions you have defined (ref). If you want more text suggestions, I'd recommend:

• Adding your own snippets for commonly used operations.
• Adding your own completions for common words.
• Adding other people's snippets through Package Control.
• You can find even more snippets on github.
• Use Zen coding (available through Package Control) or Emmet.
• There are also various packages that adjust the way code completion works. I love SublimeCodeIntel, but check out other answers to this question for more options.

As a side note, I'd really recommend installing Package control to take full advantage of the Sublime community. Some of the options above use Package control. I'd also highly recommend the tutsplus Sublime tutorial videos, which include all sorts of information about improving your efficiency when using Sublime.

You can use Tuple for constant variable :

• A tuple is a collection which is ordered and unchangeable

my_tuple = (1, "Hello", 3.4)
print(my_tuple[0])

If the branch is on something other than the origin remote I like to do the following:

$ git fetch
$ git checkout -b second/next upstream/next

This will checkout the next branch on the upstream remote in to a local branch called second/next. Which means if you already have a local branch named next it will not conflict.

$ git branch -a
* second/next
  remotes/origin/next
  remotes/upstream/next

If the attribute you want to sort by is a property, then you can avoid importing operator.attrgetter and use the property's fget method instead.

For example, for a class Circle with a property radius we could sort a list of circles by radii as follows:

result = sorted(circles, key=Circle.radius.fget)

This is not the most well-known feature but often saves me a line with the import.

Open Project properties by selecting project then go to

Just to help those in a similar situation to myself...

This can be caused when a dependent library has accidentally bundled an old version of slf4j. In my case, it was tika-0.8. See https://issues.apache.org/jira/browse/TIKA-556

The workaround is exclude the component and then manually depends on the correct, or patched version.

EG.

<dependency>
    <groupId>org.apache.tika</groupId>
    <artifactId>tika-parsers</artifactId>
    <version>0.8</version>
    <exclusions>
        <exclusion>
            <!-- NOTE: Version 4.2 has bundled slf4j -->
            <groupId>edu.ucar</groupId>
            <artifactId>netcdf</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <!-- Patched version 4.2-min does not bundle slf4j -->
    <groupId>edu.ucar</groupId>
    <artifactId>netcdf</artifactId>
    <version>4.2-min</version>
</dependency>

The accepted answer is correct and works on older versions of Android where Android OS asks for permissions at the app install, However on newer versions Android it doesn't work straight away because newer Android OS asks for permissions during runtime when the app requires that feature. Therefore in order to receive SMS on newer versions of Android using technique mentioned in accepted answer programmer must also implement code that will check and ask for permissions from user during runtime. In this case permissions checking functionality/code can be implemented in onCreate() of app's first activity. Just copy and paste following two methods in your first activity and call checkForSmsReceivePermissions() method at the end of onCreate().

    void checkForSmsReceivePermissions(){
    // Check if App already has permissions for receiving SMS
    if(ContextCompat.checkSelfPermission(getBaseContext(), "android.permission.RECEIVE_SMS") == PackageManager.PERMISSION_GRANTED) {
        // App has permissions to listen incoming SMS messages
        Log.d("adnan", "checkForSmsReceivePermissions: Allowed");
    } else {
        // App don't have permissions to listen incoming SMS messages
        Log.d("adnan", "checkForSmsReceivePermissions: Denied");

        // Request permissions from user 
        ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.RECEIVE_SMS}, 43391);
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if(requestCode == 43391){
        if(grantResults.length>0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
            Log.d("adnan", "Sms Receive Permissions granted");
        } else {
            Log.d("adnan", "Sms Receive Permissions denied");
        }
    }
}

One more reason, maybe your url include some hiden characters, such as '\n'.

If you define your url like below, this exception will raise:

url = '''
http://google.com
'''

because there are '\n' hide in the string. The url in fact become:

\nhttp://google.com\n

Here's a nice reusable hook amended from https://swizec.com/blog/usedimensions-a-react-hook-to-measure-dom-nodes:

import { useState, useCallback, useEffect } from 'react';

function getDimensionObject(node) {
  const rect = node.getBoundingClientRect();

  return {
    width: rect.width,
    height: rect.height,
    top: 'x' in rect ? rect.x : rect.top,
    left: 'y' in rect ? rect.y : rect.left,
    x: 'x' in rect ? rect.x : rect.left,
    y: 'y' in rect ? rect.y : rect.top,
    right: rect.right,
    bottom: rect.bottom
  };
}

export function useDimensions(data = null, liveMeasure = true) {
  const [dimensions, setDimensions] = useState({});
  const [node, setNode] = useState(null);

  const ref = useCallback(node => {
    setNode(node);
  }, []);

  useEffect(() => {
    if (node) {
      const measure = () =>
        window.requestAnimationFrame(() =>
          setDimensions(getDimensionObject(node))
        );
      measure();

      if (liveMeasure) {
        window.addEventListener('resize', measure);
        window.addEventListener('scroll', measure);

        return () => {
          window.removeEventListener('resize', measure);
          window.removeEventListener('scroll', measure);
        };
      }
    }
  }, [node, data]);

  return [ref, dimensions, node];
}

To implement:

import { useDimensions } from '../hooks';

// Include data if you want updated dimensions based on a change.
const MyComponent = ({ data }) => {
  const [
    ref,
    { height, width, top, left, x, y, right, bottom }
  ] = useDimensions(data);

  console.log({ height, width, top, left, x, y, right, bottom });

  return (
    <div ref={ref}>
      {data.map(d => (
        <h2>{d.title}</h2>
      ))}
    </div>
  );
};

In my case, when I run df -i it shows me that my number of inodes are full and then I have to delete some of the small files or folder. Otherwise it will not allow us to create files or folders once inodes get full.

All you have to do is delete files or folder that has not taken up full space but is responsible for filling inodes.

That's a lot of questions.

1. Why EOF is -1: usually -1 in POSIX system calls is returned on error, so i guess the idea is "EOF is kind of error"

2. any boolean operation (including !=) returns 1 in case it's TRUE, and 0 in case it's FALSE, so getchar() != EOF is 0 when it's FALSE, meaning getchar() returned EOF.

3. in order to emulate EOF when reading from stdin press Ctrl+D

@Tama, you may want to check this answer: Using Font Awesome icons as bullets

Basically you can accomplish this by using only CSS without the need for the extra markup as suggested by FontAwesome and the other answers here.

In other words, you can accomplish what you need using the same basic markup you mentioned in your initial post:

<ul>
  <li>...</li>
  <li>...</li>
  <li>...</li>
</ul>

Thanks.

Here is the solution

  {!! Html::style('css/select2.min.css') !!}
  {!! Html::script('js/select2.min.js') !!}

from pathlib import Path

data_folder = Path("source_data/text_files/")
file_to_open = data_folder / "raw_data.txt"

f = open(file_to_open)
print(f.read())

As per keras tutorial, you can simply use the same tf.device scope as in regular tensorflow:

with tf.device('/gpu:0'):
    x = tf.placeholder(tf.float32, shape=(None, 20, 64))
    y = LSTM(32)(x)  # all ops in the LSTM layer will live on GPU:0

with tf.device('/cpu:0'):
    x = tf.placeholder(tf.float32, shape=(None, 20, 64))
    y = LSTM(32)(x)  # all ops in the LSTM layer will live on CPU:0

The terms "interpreted language" or "compiled language" don't make sense, because any programming language can be interpreted and/or compiled.

As for the existing implementations of Java, most involve a compilation step to bytecode, so they involve compilation. The runtime also can load bytecode dynamically, so some form of a bytecode interpreter is always needed. That interpreter may or may not in turn use compilation to native code internally.

These days partial just-in-time compilation is used for many languages which were once considered "interpreted", for example JavaScript.

<?php
    header("Location: index.html");
?>

Just make sure nothing is actually written to the page prior to this code, or it won't work.

If you are using template files, than you can put your meta tag in the head section (or whatever you name it) which contain your meta tags.

@section('head')
<meta name="csrf_token" content="{{ csrf_token() }}" />
@endsection

Next thing, you need to put the headers attribute to your ajax(in my example, I am using datatable with server-side processing:

"headers": {'X-CSRF-TOKEN': $('meta[name="csrf_token"]').attr('content')}

Here is the full datatable ajax example:

$('#datatable_users').DataTable({
        "responsive": true,
        "serverSide": true,
        "processing": true,
        "paging": true,
        "searching": { "regex": true },
        "lengthMenu": [ [10, 25, 50, 100, -1], [10, 25, 50, 100, "All"] ],
        "pageLength": 10,
        "ajax": {
            "type": "POST",
            "headers": {'X-CSRF-TOKEN': $('meta[name="csrf_token"]').attr('content')},
            "url": "/getUsers",
            "dataType": "json",
            "contentType": 'application/json; charset=utf-8',
            "data": function (data) {
                console.log(data);
            },
            "complete": function(response) {
                console.log(response);
           }
        }
    });

After doing this, you should get 200 status for your ajax request.

You can directly use String.valueOf()

String.valueOf(charSequence)

Though this is same as toString() it does a null check on the charSequence before actually calling toString.

This is useful when a method can return either a charSequence or null value.
