you forgot for Java Desktop Aplication based on JSR296 as built-in Swing Framework in NetBeans

excluding AWT and JavaFX are all of your desribed frameworks are based on Swing, if you'll start with Swing then you'd be understand (clearly) for all these Swing's (Based Frameworks)

ATW, SWT (Eclipse), Java Desktop Aplication(Netbeans), SwingX, JGoodies

all there frameworks (I don't know something more about JGoodies) incl. JavaFX haven't long time any progress, lots of Swing's Based Frameworks are stoped, if not then without newest version

just my view - best of them is SwingX, but required deepest knowledge about Swing,

Look and Feel for Swing's Based Frameworks

Update: In an effort to answer my own question, here is what I've been able to uncover so far. If anyone else out there has something, I'd still be interested to find out more.

Spinner sp = (Spinner)findViewById(R.id.spinner); 
sp.setSelection(pos);

here pos is integer (your array item position)

array is like below then pos = 0;

String str[] = new String{"Select Gender","male", "female" };

then in onItemSelected

@Override
    public void onItemSelected(AdapterView<?> main, View view, int position,
            long Id) {

        if(position > 0){
          // get spinner value
        }else{
          // show toast select gender
        }

    }

Alternatively (just for comparison), if you have Rails installed (actually just ActiveSupport):

require 'activesupport'
array.sum

This LocaleUtils works just fine: https://gist.github.com/GigigoGreenLabs/7d555c762ba2d3a810fe

LocaleUtils

public class LocaleUtils {

public static final String LAN_SPANISH      = "es";
public static final String LAN_PORTUGUESE   = "pt";
public static final String LAN_ENGLISH      = "en";

private static Locale sLocale;

public static void setLocale(Locale locale) {
    sLocale = locale;
    if(sLocale != null) {
        Locale.setDefault(sLocale);
    }
}

public static void updateConfig(ContextThemeWrapper wrapper) {
    if(sLocale != null && Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        Configuration configuration = new Configuration();
        configuration.setLocale(sLocale);
        wrapper.applyOverrideConfiguration(configuration);
    }
}

public static void updateConfig(Application app, Configuration configuration) {
    if(sLocale != null && Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {
        //Wrapping the configuration to avoid Activity endless loop
        Configuration config = new Configuration(configuration);
        config.locale = sLocale;
        Resources res = app.getBaseContext().getResources();
        res.updateConfiguration(config, res.getDisplayMetrics());
    }
}
}

Added this code to Application

public class App extends Application {
public void onCreate(){
    super.onCreate();

    LocaleUtils.setLocale(new Locale("iw"));
    LocaleUtils.updateConfig(this, getBaseContext().getResources().getConfiguration());
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    LocaleUtils.updateConfig(this, newConfig);
}
}

Code in Activity

public class BaseActivity extends AppCompatActivity {
    public BaseActivity() {
        LocaleUtils.updateConfig(this);
    }
}

Using a button tag instead of the input, resetting it and put a span inside, you'll then just have to style both the link and the span in the same way. It involve extra markup, but it worked for me.

the markup:

<button type="submit">
    <span>submit</span>
</button>
<a>cancel</a>

the css:

button[type="submit"] {
    display: inline;
    border: none;
    padding: 0;
    background: none;
}

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();  
GraphicsDevice[] screens = ge.getScreenDevices();       
Rectangle allScreenBounds = new Rectangle();  
for (GraphicsDevice screen : screens) {  
       Rectangle screenBounds = screen.getDefaultConfiguration().getBounds();        
       allScreenBounds.width += screenBounds.width;  
       allScreenBounds.height = Math.max(allScreenBounds.height, screenBounds.height);
       allScreenBounds.x=Math.min(allScreenBounds.x, screenBounds.x);
       allScreenBounds.y=Math.min(allScreenBounds.y, screenBounds.y);
      } 
Robot robot = new Robot();
BufferedImage bufferedImage = robot.createScreenCapture(allScreenBounds);
File file = new File("C:\\Users\\Joe\\Desktop\\scr.png");
if(!file.exists())
    file.createNewFile();
FileOutputStream fos = new FileOutputStream(file);
ImageIO.write( bufferedImage, "png", fos );

bufferedImage will contain a full screenshot, this was tested with three monitors

As commented on the approved story, the HttpServerUtility.UrlEncode method replaces spaces with + instead of %20. Use one of these two methods instead: Uri.EscapeUriString() or Uri.EscapeDataString()

Sample code:

HttpUtility.UrlEncode("https://mywebsite.com/api/get me this file.jpg")
//Output: "https%3a%2f%2fmywebsite.com%2fapi%2fget+me+this+file.jpg"

Uri.EscapeUriString("https://mywebsite.com/api/get me this file.jpg");
//Output: "https://mywebsite.com/api/get%20me%20this%20file.jpg"
Uri.EscapeDataString("https://mywebsite.com/api/get me this file.jpg");
//Output: "https%3A%2F%2Fmywebsite.com%2Fapi%2Fget%20me%20this%20file.jpg"

//When your url has a query string:
Uri.EscapeUriString("https://mywebsite.com/api/get?id=123&name=get me this file.jpg");
//Output: "https://mywebsite.com/api/get?id=123&name=get%20me%20this%20file.jpg"
Uri.EscapeDataString("https://mywebsite.com/api/get?id=123&name=get me this file.jpg");    
//Output: "https%3A%2F%2Fmywebsite.com%2Fapi%2Fget%3Fid%3D123%26name%3Dget%20me%20this%20file.jpg"

Following this resource page, if the length of x is varying, we can use:

', '.join(['%.2f']*len(x))

to create a place holder for each element from the list x. Here is the example:

x = [1/3.0, 1/6.0, 0.678]
s = ("elements in the list are ["+', '.join(['%.2f']*len(x))+"]") % tuple(x)
print s
>>> elements in the list are [0.33, 0.17, 0.68]

As of OpenCV 2.2.0, the package name for the Python bindings is "cv".The old bindings named "opencv" are not maintained any longer. You might have to adjust your code. See http://opencv.willowgarage.com/wiki/PythonInterface.

The official OpenCV installer does not install the Python bindings into your Python directory. There should be a Python2.7 directory inside your OpenCV 2.2.0 installation directory. Copy the whole Lib folder from OpenCV\Python2.7\ to C:\Python27\ and make sure your OpenCV\bin directory is in the Windows DLL search path.

Alternatively use the opencv-python installers at http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv.

It's a unicode character. In this case \u003C and \u003E mean :

U+003C < Less-than sign

U+003E > Greater-than sign

In my case, im getting the similar exception when trying to checkout the project from SVN repo it is prompting for the username and password and i was giving the wrong username every time, when i gave the correct username and password its started working fine..... Such a simple and Hardstopping message.....

In case anyone else is interested to know how to import files/packages from gdrive inside a google colab. The following procedure worked for me:

1) Mount your google drive in google colab:

from google.colab import drive
drive.mount('/content/gdrive/')

2) Append the directory to your python path using sys:

import sys
sys.path.append('/content/gdrive/mypythondirectory')

Now you should be able to import stuff from that directory!

The easiest way i found to solve that problem was to select a label and then send:

label.sendKeys(Keys.PAGE_DOWN);

Hope it works!

Angular filters can only be applied to arrays and not objects, from angular's API -

"Selects a subset of items from array and returns it as a new array."

You have two options here:
1) move $scope.items to an array or -
2) pre-filter the ng-repeat items, like this:

<div ng-repeat="(k,v) in filterSecId(items)">
    {{k}} {{v.pos}}
</div>

And on the Controller:

$scope.filterSecId = function(items) {
    var result = {};
    angular.forEach(items, function(value, key) {
        if (!value.hasOwnProperty('secId')) {
            result[key] = value;
        }
    });
    return result;
}

I've had some minor issues when updating the ViewControllers view using UIDevice.current.orientation, such as updating constraints of tableview cells during rotation or animation of subviews.

Instead of the above methods I am currently comparing the transition size to the view controllers view size. This seems like the proper way to go since one has access to both at this point in code:

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)
    print("Will Transition to size \(size) from super view size \(self.view.frame.size)")

    if (size.width > self.view.frame.size.width) {
        print("Landscape")
    } else {
        print("Portrait")
    }

    if (size.width != self.view.frame.size.width) {
        // Reload TableView to update cell's constraints.
    // Ensuring no dequeued cells have old constraints.
        DispatchQueue.main.async {
            self.tableView.reloadData()
        }
    }


}

Output on a iPhone 6:

Will Transition to size (667.0, 375.0) from super view size (375.0, 667.0) 
Will Transition to size (375.0, 667.0) from super view size (667.0, 375.0)

A suggestion of code that I just used in my project using AngularJS v1.7.2

$http.get('LabelsPDF?ids=' + ids, { responseType: 'arraybuffer' })
            .then(function (response) {
                var file = new Blob([response.data], { type: 'application/pdf' });
                var fileURL = URL.createObjectURL(file);
                $scope.ContentPDF = $sce.trustAsResourceUrl(fileURL);
            });

<embed ng-src="{{ContentPDF}}" type="application/pdf" class="col-xs-12" style="height:100px; text-align:center;" />

we can use append and pop to do it

def rev(s):
    i = list(s)
    o = list()
    while len(i) > 0:
        o.append(t.pop())

    return ''.join(o)

This allows to send text message through existing app. phoneNumber - is String. If you do not wish to specify phone number, use empty string "".

Intent sendIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("smsto", phoneNumber, null));
sendIntent.putExtra("sms_body", "text message");
startActivity(sendIntent);

It looks suspicious because there is no apparent function that is being returned from!

It is an anonymous function that has been attached to the click event of the object.

why are you doing this, Steve?

Why on earth are you doi.....Ah nevermind, as you've mentioned, it really is widely adopted bad practice :)

Without more details as to what the question is exactly asking, I am going to answer the title of the question,

Create an Array:

String[] myArray = new String[2];
int[] intArray = new int[2];

// or can be declared as follows
String[] myArray = {"this", "is", "my", "array"};
int[] intArray = {1,2,3,4};

Create an ArrayList:

ArrayList<String> myList = new ArrayList<String>();
myList.add("Hello");
myList.add("World");

ArrayList<Integer> myNum = new ArrayList<Integer>();
myNum.add(1);
myNum.add(2);

This means, create an ArrayList of String and Integer objects. You cannot use int because thats a primitive data types, see the link for a list of primitive data types.

Create a Stack:

Stack myStack = new Stack();
// add any type of elements (String, int, etc..)
myStack.push("Hello");
myStack.push(1);

Create an Queue: (using LinkedList)

Queue<String> myQueue = new LinkedList<String>();
Queue<Integer> myNumbers = new LinkedList<Integer>();
myQueue.add("Hello");
myQueue.add("World");
myNumbers.add(1);
myNumbers.add(2);

Same thing as an ArrayList, this declaration means create an Queue of String and Integer objects.

Update:

In response to your comment from the other given answer,

i am pretty confused now, why are using string. and what does <String> means

We are using String only as a pure example, but you can add any other object, but the main point is that you use an object not a primitive type. Each primitive data type has their own primitive wrapper class, see link for list of primitive data type's wrapper class.

I have posted some links to explain the difference between the two, but here are a list of primitive types

• byte
• short
• char
• int
• long
• boolean
• double
• float

Which means, you are not allowed to make an ArrayList of integer's like so:

ArrayList<int> numbers = new ArrayList<int>(); 
           ^ should be an object, int is not an object, but Integer is!
ArrayList<Integer> numbers = new ArrayList<Integer>();
            ^ perfectly valid

Also, you can use your own objects, here is my Monster object I created,

public class Monster {
   String name = null;
   String location = null;
   int age = 0;

public Monster(String name, String loc, int age) { 
   this.name = name;
   this.loc = location;
   this.age = age;
 }

public void printDetails() {
   System.out.println(name + " is from " + location +
                                     " and is " + age + " old.");
 }
} 

Here we have a Monster object, but now in our Main.java class we want to keep a record of all our Monster's that we create, so let's add them to an ArrayList

public class Main {
    ArrayList<Monster> myMonsters = new ArrayList<Monster>();

public Main() {
    Monster yetti = new Monster("Yetti", "The Mountains", 77);
    Monster lochness = new Monster("Lochness Monster", "Scotland", 20);

    myMonsters.add(yetti); // <-- added Yetti to our list
    myMonsters.add(lochness); // <--added Lochness to our list
  
    for (Monster m : myMonsters) {
        m.printDetails();
     }
   }

public static void main(String[] args) {
    new Main();
 }
}

(I helped my girlfriend's brother with a Java game, and he had to do something along those lines as well, but I hope the example was well demonstrated)

Not really a reliable method, better of using JodaTime

  Calendar thatDay = Calendar.getInstance();
  thatDay.set(Calendar.DAY_OF_MONTH,25);
  thatDay.set(Calendar.MONTH,7); // 0-11 so 1 less
  thatDay.set(Calendar.YEAR, 1985);

  Calendar today = Calendar.getInstance();

  long diff = today.getTimeInMillis() - thatDay.getTimeInMillis(); //result in millis

Here's an approximation...

long days = diff / (24 * 60 * 60 * 1000);

To Parse the date from a string, you could use

  String strThatDay = "1985/08/25";
  SimpleDateFormat formatter = new SimpleDateFormat("yyyy/MM/dd");
  Date d = null;
  try {
   d = formatter.parse(strThatDay);//catch exception
  } catch (ParseException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } 


  Calendar thatDay = Calendar.getInstance();
  thatDay.setTime(d); //rest is the same....

Although, since you're sure of the date format... You Could also do Integer.parseInt() on it's Substrings to obtain their numeric values.

This can be confusing for anyone using nodejs for the first time. It is actually possible to pipe your node console output to the browser console. Take a look at connect-browser-logger on github

UPDATE: As pointed out by Yan, connect-browser-logger appears to be defunct. I would recommend NodeMonkey as detailed here : Output to Chrome console from Node.js

What's the memory profile of your machine ? e.g. if you run top, how much free memory do you have ?

I suspect UnixProcess performs a fork() and it's simply not getting enough memory from the OS (if memory serves, it'll fork() to duplicate the process and then exec() to run the ls in the new memory process, and it's not getting as far as that)

EDIT: Re. your overcommit solution, it permits overcommitting of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available. So I guess that the fork() duplicates the Java process memory as discussed in the comments below. Of course you don't use the memory since the 'ls' replaces the duplicate Java process.

Changing the build verbosity in visual studio will help to point in the right direction. Follow the below steps to change verbosity in VS

1. Go to Tools->Options menu in VS
2. Open Projects and Solutions->Build and Run
3. Change the value of the MSBuild project build output verbosity. Pick one from Quiet, Minimal, Normal, Detailed and Diagnostic

Check the output window(Ctrl+Alt+O) in VS to see the changes in the build log.

UPDATE table
SET A = IF(A > 0 AND A < 1, 1, IF(A > 1 AND A < 2, 2, A))
WHERE A IS NOT NULL;

you might want to use CEIL() if A is always a floating point value > 0 and <= 2

Simple & clear:

String manType = hasMoney() ? "rich" : "poor";

long version:

      String manType;
    if (hasMoney()) {
        manType = "rich";
    } else {
        manType = "poor";
    }

or how I'm using it to be clear for other code readers:

 String manType = "poor";
    if (hasMoney())
        manType = "rich";

I ran into this and what worked for me was to run yum localinstall enterPkgNameHere.rpm from inside the directory where the .rpm file is located.

Note: replace the enterPkgNameHere.rpm with the name of your .rpm file.

If you need to show Form2 as a modal dialog, from within Form1 do:

var form2 = new Form2();
if (form2.ShowDialog() == DialogResult.OK) 
{
    // process results here
}

A modal dialog will retain focus while it is open; it will set the parent windows (Form1) "in the background" until it is closed, which is quite a common practice for settings windows.

If I were doing this I would probably use WCF REST on the server and a REST library on the Java/Android client.

Did you include "bootstrap-theme.css" files on your code?

In "bootstrap-theme.min.css" files, background-image about ".active" is existed for "navbar" (check this screenshot: http://i.imgur.com/1etLIyY.png).

It will re-declare your style code, and then it will be effected on your code.

So after you delete or re-declare them (background-image), you can use your background color style about the ".active" tag.

The first element of the sites array is an array, as you can see indenting the JSON:

{"units":[{"id":42,               
    ...
    "sites":
    [
      [
        {
          "id":316,
          "article":42,
          "clip":133904
        }
      ],
      {"length":5}
    ]
    ...
}

Therefore you need to treat its value accordingly; probably you could do something like:

JSONObject site = (JSONObject)(((JSONArray)jsonSites.get(i)).get(0));

AWS CLI can let you see all files of an S3 bucket quickly and help in performing other operations too.

To use AWS CLI follow steps below:

1. Install AWS CLI.
2. Configure AWS CLI for using default security credentials and default AWS Region.

3. To see all files of an S3 bucket use command

   aws s3 ls s3://your_bucket_name --recursive

Reference to use AWS cli for different AWS services: https://docs.aws.amazon.com/cli/latest/reference/

OK, first of all I'm not sure how it works when you create a div using (document.createElement('div')), so I might be wrong now, but wouldn't it be possible to use the :target pseudo class selector for this?

If you look at the code below, you can se I've used a link to target the div, but in your case it might be possible to target #new from the script instead and that way make the div fade in without user interaction, or am I thinking wrong?

Here's the code for my example:

HTML

<a href="#new">Click</a> 
<div id="new">
    Fade in ... 
</div>

CSS

#new {
    width: 100px;
    height: 100px;
    border: 1px solid #000000;
    opacity: 0;    
}


#new:target {
    -webkit-transition: opacity 2.0s ease-in;
       -moz-transition: opacity 2.0s ease-in;
         -o-transition: opacity 2.0s ease-in;
                                  opacity: 1;
}

... and here's a jsFiddle

{{ app.user.username|default('') }}

Just present login username for example, filter function default('') should be nice when user is NOT login by just avoid annoying error message.

This is no longer possible in modern browsers due to security restrictions.

Official(-ish) Sources:

• Firefox

  In Firefox 3, dom.disable_window_open_feature.location now defaults to true, forcing the presence of the Location Bar much like in IE7. See bug 337344 for more information.

• Internet Explorer 7 and later

  In Internet Explorer 6, location specifies whether to display the Address Bar.

  (Implying the behaviour ends with IE6)

• Chrome/Chromium

  Those toolbar hiding parameters are ignored in Chrome. You will also notice that modern browsers are moving towards not hiding it as security / anti phishing measures. Also see https://bugzilla.mozilla.org/show_bug.cgi?id=337344

You can add a .env file in all your projects containing COMPOSE_PROJECT_NAME=somename.

COMPOSE_PROJECT_NAME overrides the prefix used to name resources, as such all your projects will use somename_default as their network, making it possible for services to communicate with each other as they were in the same project.

NB: You'll get warnings for "orphaned" containers created from other projects.

I didn't see an answer that's clean and suitable for production-ready software, so here it goes:

/*
 * Get current error_reporting value,
 * so that we don't lose preferences set in php.ini and .htaccess
 * and accidently reenable message types disabled in those.
 *
 * If you want to disable e.g. E_STRICT on a global level,
 * use php.ini (or .htaccess for folder-level)
 */
$old_error_reporting = error_reporting();

/*
 * Disable E_STRICT on top of current error_reporting.
 *
 * Note: do NOT use ^ for disabling error message types,
 * as ^ will re-ENABLE the message type if it happens to be disabled already!
 */
error_reporting($old_error_reporting & ~E_STRICT);


// code that should not emit E_STRICT messages goes here


/*
 * Optional, depending on if/what code comes after.
 * Restore old settings.
 */
error_reporting($old_error_reporting);

Maybe this is useful to anyone in the future, I have implemented a custom Authorize Attribute like this:

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class ClaimAuthorizeAttribute : AuthorizeAttribute, IAuthorizationFilter
{
    private readonly string _claim;

    public ClaimAuthorizeAttribute(string Claim)
    {
        _claim = Claim;
    }

    public void OnAuthorization(AuthorizationFilterContext context)
    {
        var user = context.HttpContext.User;
        if(user.Identity.IsAuthenticated && user.HasClaim(ClaimTypes.Name, _claim))
        {
            return;
        }

        context.Result = new ForbidResult();
    }
}

You've got two common situations. The first is that you want random numbers and aren't too fussed about the quality or execution speed. In that case, use the following macro

#define uniform() (rand()/(RAND_MAX + 1.0))

that gives you p in the range 0 to 1 - epsilon (unless RAND_MAX is bigger than the precision of a double, but worry about that when you come to it).

int x = (int) (uniform() * N);

Now gives a random integer on 0 to N -1.

If you need other distributions, you have to transform p. Or sometimes it's easier to call uniform() several times.

If you want repeatable behaviour, seed with a constant, otherwise seed with a call to time().

Now if you are bothered about quality or run time performance, rewrite uniform(). But otherwise don't touch the code. Always keep uniform() on 0 to 1 minus epsilon. Now you can wrap the C++ random number library to create a better uniform(), but that's a sort of medium-level option. If you are bothered about the characteristics of the RNG, then it's also worth investing a bit of time to understand how the underlying methods work, then provide one. So you've got complete control of the code, and you can guarantee that with the same seed, the sequence will always be exactly the same, regardless of platform or which version of C++ you are linking to.

I got this error in the context of angular tree control. In my case it was the tree options. I was returning treeOptions() from a function. It was always returning the same object. But Angular magically thinks that its a new object and then cause a digest cycle to kick off. Causing a recursion of digests. The solution was to bind the treeOptions to scope. And assign it just once.

String value = "True";
boolean result = value.equalsIgnoreCase("true") ? true : false;

I discovered that you can also do Device Manager -> Update Driver Software -> Browse my computer for driver software -> Let me pick from a list of device drivers on my computer -> Android Phone -> [ADB driver version 6 near top of list... sorry, I can't remember exact name]

As soon as I did that, it connected, and I was able to sideload version 4.2 on Windows 7 64 bit.

Use sudo instead

EDIT: As Douglas pointed out, you can not use cd in sudo since it is not an external command. You have to run the commands in a subshell to make the cd work.

sudo -u $USERNAME -H sh -c "cd ~/$PROJECT; svn update"

sudo -u $USERNAME -H cd ~/$PROJECT
sudo -u $USERNAME svn update

You may be asked to input that user's password, but only once.

C++ provides a good mechanism to manage the life time of an object though class/struct constructs. This is one of the best features of C++ over other languages.

When you have member variables exposed through ref or pointer it violates the encapsulation in principle. This idiom enables the consumer of the class to change the state of an object of A without it(A) having any knowledge or control of it. It also enables the consumer to hold on to a ref/pointer to A's internal state, beyond the life time of the object of A. This is bad design. Instead the class could be refactored to hold a ref/pointer to the shared object (not own it) and these could be set using the constructor (Mandate the life time rules). The shared object's class may be designed to support multithreading/concurrency as the case may apply.

Here is how to do dump the database (with just the schema):

mysqldump -u root -p"passwd" --no-data --add-drop-database --databases my_db_name | sed 's#/[*]!40000 DROP DATABASE IF EXISTS my_db_name;#' >my_db_name.sql

If you also want the data, remove the --no-data option.

I have also encountered this error . Just i opened the new window ie Window -> New Window in eclipse .Then , I closed my old window. This solved my problem.

Going forward, the new HTML Intersection Observer API is the thing you're looking for. It allows you to configure a callback that is called whenever one element, called the target, intersects either the device viewport or a specified element. It's available in latest versions of Chrome, Firefox and Edge. See https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API for more info.

Simple code example for observing display:none switching:

// Start observing visbility of element. On change, the
//   the callback is called with Boolean visibility as
//   argument:

function respondToVisibility(element, callback) {
  var options = {
    root: document.documentElement,
  };

  var observer = new IntersectionObserver((entries, observer) => {
    entries.forEach(entry => {
      callback(entry.intersectionRatio > 0);
    });
  }, options);

  observer.observe(element);
}

Use the % wildcard, which matches any number of characters.

SELECT * FROM Accounts WHERE Username LIKE '%query%'

This may help:

ls -l| grep -v '^d'| awk '{total = total + $5} END {print "Total" , total}'

The above command will sum total all the files leaving the directories size.

I encountered the same error while using Server Management Objects (SMO) in vb.net (I'm sure it's the same in C#)

Techie Joe's comment on the initial post was a useful warning that in shared hosting a lot of additional things are going on. It took a little time to figure out, but the code below shows how one has to be very specific in the way they access SQL databases. The 'server principal...' error seemed to show up whenever the SMO calls were not precisely specific in the shared hosting environment.

This first section of code was against a local SQL Express server and relied on simple Windows Authentication. All the code used in these samples are based on the SMO tutorial by Robert Kanasz in this Code Project website article:

  Dim conn2 = New ServerConnection()
  conn2.ServerInstance = "<local pc name>\SQLEXPRESS"
  Try
    Dim testConnection As New Server(conn2)
    Debug.WriteLine("Server: " + testConnection.Name)
    Debug.WriteLine("Edition: " + testConnection.Information.Edition)
    Debug.WriteLine(" ")

    For Each db2 As Database In testConnection.Databases
      Debug.Write(db2.Name & " - ")
      For Each fg As FileGroup In db2.FileGroups
        Debug.Write(fg.Name & " - ")
        For Each df As DataFile In fg.Files
          Debug.WriteLine(df.Name + " - " + df.FileName)
        Next
      Next
    Next
    conn2.Disconnect()

  Catch err As Exception
    Debug.WriteLine(err.Message)
  End Try

The code above finds the .mdf files for every database on the local SQLEXPRESS server just fine because authentication is handled by Windows and it is broad across all the databases.

In the following code there are 2 sections iterating for the .mdf files. In this case only the first iteration looking for a filegroup works, and it only finds a single file because the connection is to only a single database in the shared hosting environment.

The second iteration, which is a copy of the iteration that worked above, chokes immediately because the way it is written it tries to access the 1st database in the shared environment, which is not the one to which the User ID/Password apply, so the SQL server returns an authorization error in the form of the 'server principal...' error.

Dim sqlConnection1 As New System.Data.SqlClient.SqlConnection
sqlConnection1.ConnectionString = "connection string with User ID/Password to a specific database in a shared hosting system. This string will likely also include the Data Source and Initial Catalog parameters"
Dim conn1 As New ServerConnection(sqlConnection1)
Try
  Dim testConnection As New Server(conn1)
  Debug.WriteLine("Server: " + testConnection.Name)
  Debug.WriteLine("Edition: " + testConnection.Information.Edition)
  Debug.WriteLine(" ")

  Dim db2 = testConnection.Databases("the name of the database to which the User ID/Password in the connection string applies")
  For Each fg As FileGroup In db2.FileGroups
    Debug.Write(fg.Name & " - ")
    For Each df As DataFile In fg.Files
      Debug.WriteLine(df.Name + " - " + df.FileName)
    Next
  Next

  For Each db3 As Database In testConnection.Databases
    Debug.Write(db3.Name & " - ")
    For Each fg As FileGroup In db3.FileGroups
      Debug.Write(fg.Name & " - ")
      For Each df As DataFile In fg.Files
        Debug.WriteLine(df.Name + " - " + df.FileName)
      Next
    Next
  Next

  conn1.Disconnect()

Catch err As Exception
  Debug.WriteLine(err.Message)
End Try

In that second iteration loop, the code compiles fine, but because SMO wasn't setup to access precisely the correct database with the precise syntax, that attempt fails.

As I'm just learning SMO I thought other newbies might appreciate knowing there's also a more simple explanation for this error - we just coded it wrong.

you may use opacity:0.5;//what ever you wish between 0 and 1 for this.

working Fiddle

You should also be aware of the fact, that with utf8_general_ci when using a varchar field as unique or primary index inserting 2 values like 'a' and 'á' would give a duplicate key error.

You could also pass points to the function: Small example:

def test(points):
    addpoint = raw_input ("type ""add"" to add a point")
    if addpoint == "add":
        points = points + 1
    else:
        print "asd"
    return points;
if __name__ == '__main__':
    points = 0
    for i in range(10):
        points = test(points)
        print points

This errors have two common causes: The element has been deleted entirely, or the element is no longer attached to the DOM.

If you already checked if it is not your case, you could be facing the same problem as me.

The element in the DOM is not found because your page is not entirely loaded when Selenium is searching for the element. To solve that, you can put an explicit wait condition that tells Selenium to wait until the element is available to be clicked on.

from selenium.webdriver.support import expected_conditions as EC

wait = WebDriverWait(driver, 10)
element = wait.until(EC.element_to_be_clickable((By.ID, 'someid')))

See: https://selenium-python.readthedocs.io/waits.html

In Python 3.x, the single slash (/) always means true (non-truncating) division. (The // operator is used for truncating division.) In Python 2.x (2.2 and above), you can get this same behavior by putting a

from __future__ import division

at the top of your module.

Try this one : new String(byte[])

It seems that your

$(".modal").on('shown.bs.modal')   // One way Or

You can do this in a slight different way, like this

$('.btn').click(function(){
    // Send the src on click of button to the iframe. Which will make it load.
    $(".openifrmahere").find('iframe').attr("src","http://www.hf-dev.info");
    $('.modal').modal({show:true});
    // Hide the loading message
    $(".openifrmahere").find('iframe').load(function() {
        $('.loading').hide();
    });
})

Buffering of output depends on how your program /homedir/MyScript is implemented. If you find that output is getting buffered, you have to force it in your implementation. For example, use sys.stdout.flush() if it's a python program or use fflush(stdout) if it's a C program.

I'm also reading an exported file which contains french and German languages. I used Encoding.GetEncoding("iso-8859-1"), true which worked out without any challenges.

Any line starting with a "REM" is treated as a comment, nothing is executed including the redirection.

Also, the %date% variable may contain "/" characters which are treated as path separator characters, leading to the system being unable to create the desired log file.

This was supposed to get closer to other databases, and ease migrations. But it's not perfect to me, for instance SQL developer won't display it nicely as a normal SELECT.

I prefer the output of pipeline functions, but they need more boilerplate to code.

Edit : After Android Studios 1.5 android support Vector Asset Studio.

Follow this, which says:

To start Vector Asset Studio:

1. In Android Studio, open an Android app project.
2. In the Project window, select the Android view.
3. Right-click the res folder and select New > Vector Asset.

If you have cells with something like ="" and don't want to count them, you have to subtract number of empty cells from total number of cell by formula like

=row(G101)-row(G4)+1-countblank(G4:G101)

In case of 2-dimensional array it would be

=(row(G101)-row(A4)+1)*(column(G101)-column(A4)+1)-countblank(A4:G101)

Tested at google docs.

Following up to @edovino's answer, the way of clearing all of an application's preferences programmatically would be

        runtime.exec("pm clear YOUR_APP_PACKAGE_GOES HERE");

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

Warning: the application will force close.

I wonder (and I'm really just throwing the idea out there to be shot down) if something could be derived by subtracting one image from the other, and then compressing the resulting image as a jpeg of gif, and taking the file size as a measure of similarity.

If you had two identical images, you'd get a white box, which would compress really well. The more the images differed, the more complex it would be to represent, and hence the less compressible.

Probably not an ideal test, and probably much slower than necessary, but it might work as a quick and dirty implementation.

Make sure your iframe is already loaded. Old but reliable way without jQuery:

<iframe src="samedomain.com/page.htm" id="iframe" onload="access()"></iframe>

<script>
function access() {
   var iframe = document.getElementById("iframe");
   var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
   console.log(innerDoc.body);
}
</script>

There's always the official page: [OpenSSL.Wiki]: Binaries which contains useful URLs.

I also want to mention: [GitHub]: CristiFati/Prebuilt-Binaries - Prebuilt-Binaries/OpenSSL

You might also gain a very subsquent performance boost by changing the following Git configuration:

When running the simple git status command on Window 7 x64, it took my computer more than 30 seconds to run. After this option was defined, the command is immediate.

Based on my experience, solution which is fine(the best) when keys are not important:

$cart = [];
$cart[] = 13;
$cart[] = "foo";
$cart[] = obj;

You have to do this:

class Bar : public Foo
{
    // ...
}

The default inheritance type of a class in C++ is private, so any public and protected members from the base class are limited to private. struct inheritance on the other hand is public by default.

Horizontal centering is as easy as:

text-align: center

Vertical centering when the container is a known height:

height: 100px;
line-height: 100px;
vertical-align: middle

Vertical centering when the container isn't a known height AND you can set the image in the background:

background: url(someimage) no-repeat center center;

adjust video start and end time when using the video tag in html5;

DB Transaction Log Shrink to min size:

1. Backup: Transaction log
2. Shrink files: Transaction log
3. Backup: Transaction log
4. Shrink files: Transaction log

I made tests on several number of DBs: this sequence works.

It usually shrinks to 2MB.

OR by a script:

DECLARE @DB_Name nvarchar(255);
DECLARE @DB_LogFileName nvarchar(255);
SET @DB_Name = '<Database Name>';               --Input Variable
SET @DB_LogFileName = '<LogFileEntryName>';         --Input Variable

Several GUI tools like Squirrel, SQL Workbench/J, AnySQL, ExecuteQuery can export to Excel files.

Most of those tools are listed in the PostgreSQL wiki:

http://wiki.postgresql.org/wiki/Community_Guide_to_PostgreSQL_GUI_Tools

You can use the ATL text conversion macros to convert a narrow (char) string to a wide (wchar_t) one. For example, to convert a std::string:

#include <atlconv.h>
...
std::string str = "Hello, world!";
CA2W pszWide(str.c_str());
loadU(pszWide);

You can also specify a code page, so if your std::string contains UTF-8 chars you can use:

CA2W pszWide(str.c_str(), CP_UTF8);

Very useful but Windows only.

In general terms I would recommend the following:

• Return IQueryable<T> if you want to enable the developer using your method to refine the query you return before executing.

• Return IEnumerable if you want to transport a set of Objects to enumerate over.

Imagine an IQueryable as that what it is - a "query" for data (which you can refine if you want to). An IEnumerable is a set of objects (which has already been received or was created) over which you can enumerate.

If you want only those commits which are done by you in a particular branch, use the below command.

git log branch_name --author='Dyaniyal'

Listen to @milkplusvellocet, I'd recommend you to implement the Comparable interface to your class as well.

Just contributing to the answers of others:

String.compareTo() will tell you how different a string is from another.

e.g. System.out.println( "Test".compareTo("Tesu") ); will print -1 and System.out.println( "Test".compareTo("Tesa") ); will print 19

and nerdy and geeky one-line solution to this task would be:

return this.lastName.equals(s.getLastName()) ? this.lastName.compareTo(s.getLastName()) : this.firstName.compareTo(s.getFirstName());

Explanation:

this.lastName.equals(s.getLastName()) checks whether lastnames are the same or not this.lastName.compareTo(s.getLastName()) if yes, then returns comparison of last name. this.firstName.compareTo(s.getFirstName()) if not, returns the comparison of first name.

Thanks All, I found how to do it, which is the same as Dave and Sergey:

I am using QT Creator:

In the main GUI window create using the drag drop GUI and create label (e.g. "myLabel")

In the callback of the button (clicked) do the following using the (*ui) pointer to the user interface window:

void MainWindow::on_pushButton_clicked()
{
     QImage imageObject;
     imageObject.load(imagePath);
     ui->myLabel->setPixmap(QPixmap::fromImage(imageObject));

     //OR use the other way by setting the Pixmap directly

     QPixmap pixmapObject(imagePath");
     ui->myLabel2->setPixmap(pixmapObject);
}

//For mumbai time diffrence is 5.5 hrs so
// city_time_diff=5.5 (change according to your city) 

let timee= Date.now()
    timee=timee+(3600000*city_time_diff); //Add our city time (in msec) 
    let new_date=new Date(timee)
console.log("My city time is: ",new_date);

If you are using Python 3.4 or newer, a convenient way to move up multiple directories is pathlib:

from pathlib import Path

full_path = "path/to/directory"
str(Path(full_path).parents[0])  # "path/to"
str(Path(full_path).parents[1])  # "path"
str(Path(full_path).parents[2])  # "."

I have finally managed to properly add back button to actionbar/toolbar

@Override
public void onCreate(Bundle savedInstanceState) {
    ...
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}  

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            finish();
            return true;
    }

    return super.onOptionsItemSelected(item);
}

public boolean onCreateOptionsMenu(Menu menu) {
    return true;
}

You can try this:

function checkIfExistingValue(obj, key, value) {
    return obj.hasOwnProperty(key) && obj[key] === value;
}
var test = [{name : "jack", sex: F}, {name: "joe", sex: M}]
console.log(test.some(function(person) { return checkIfExistingValue(person, "name", "jack"); }));

The problem seems to be that you have misunderstood how async/await work with Entity Framework.

About Entity Framework

So, let's look at this code:

public IQueryable<URL> GetAllUrls()
{
    return context.Urls.AsQueryable();
}

and example of it usage:

repo.GetAllUrls().Where(u => <condition>).Take(10).ToList()

What happens there?

1. We are getting IQueryable object (not accessing database yet) using repo.GetAllUrls()
2. We create a new IQueryable object with specified condition using .Where(u => <condition>
3. We create a new IQueryable object with specified paging limit using .Take(10)
4. We retrieve results from database using .ToList(). Our IQueryable object is compiled to sql (like select top 10 * from Urls where <condition>). And database can use indexes, sql server send you only 10 objects from your database (not all billion urls stored in database)

Okay, let's look at first code:

public async Task<IQueryable<URL>> GetAllUrlsAsync()
{
    var urls = await context.Urls.ToListAsync();
    return urls.AsQueryable();
}

With the same example of usage we got:

1. We are loading in memory all billion urls stored in your database using await context.Urls.ToListAsync();.
2. We got memory overflow. Right way to kill your server

About async/await

Why async/await is preferred to use? Let's look at this code:

var stuff1 = repo.GetStuff1ForUser(userId);
var stuff2 = repo.GetStuff2ForUser(userId);
return View(new Model(stuff1, stuff2));

What happens here?

1. Starting on line 1 var stuff1 = ...
2. We send request to sql server that we want to get some stuff1 for userId
3. We wait (current thread is blocked)
4. We wait (current thread is blocked)
5. .....
6. Sql server send to us response
7. We move to line 2 var stuff2 = ...
8. We send request to sql server that we want to get some stuff2 for userId
9. We wait (current thread is blocked)
10. And again
11. .....
12. Sql server send to us response
13. We render view

So let's look to an async version of it:

var stuff1Task = repo.GetStuff1ForUserAsync(userId);
var stuff2Task = repo.GetStuff2ForUserAsync(userId);
await Task.WhenAll(stuff1Task, stuff2Task);
return View(new Model(stuff1Task.Result, stuff2Task.Result));

What happens here?

1. We send request to sql server to get stuff1 (line 1)
2. We send request to sql server to get stuff2 (line 2)
3. We wait for responses from sql server, but current thread isn't blocked, he can handle queries from another users
4. We render view

Right way to do it

So good code here:

using System.Data.Entity;

public IQueryable<URL> GetAllUrls()
{
   return context.Urls.AsQueryable();
}

public async Task<List<URL>> GetAllUrlsByUser(int userId) {
   return await GetAllUrls().Where(u => u.User.Id == userId).ToListAsync();
}

Note, than you must add using System.Data.Entity in order to use method ToListAsync() for IQueryable.

Note, that if you don't need filtering and paging and stuff, you don't need to work with IQueryable. You can just use await context.Urls.ToListAsync() and work with materialized List<Url>.

I think it's better to use the chrome toggle device toolbar with the chrome inspector. It provides you a user agent switch along with responsive mode.

To add to bhadra's list of idiomatic guides:

Checkout Anthony Baxter's presentation on Effective Python Programming (from OSON 2005).

An excerpt:

# dict's setdefault method turns this:
if key in dictobj:
    dictobj[key].append(val)
else:
    dictobj[key] = [val]
# into this:
dictobj.setdefault(key,[]).append(val)

Views are added "directly" by calling [view addSubview:subview]. Views are added "indirectly" by methods such as tab bars or nav bars that swap subviews.

Any time you call [view addSubview:subviewController.view], you should then call [subviewController viewWillAppear:NO] (or YES as your case may be).

I had this problem when I implemented my own custom root-view management system for a subscreen in a game. Manually adding the call to viewWillAppear cured my problem.

If you can, I strongly suggest you tar and bzip (or gzip, whatever floats your boat) the directory on the remote machine—for a directory of any significant size, the bandwidth savings will probably be worth the time to zip/unzip.

This answer was so obvious and it took me forever to figure out:

echo "foo
bar";

I know that looks like it's wrapping. It's not. What I did is I literally hit return halfway through the string, between foo and bar. It creates a new line in the HTML source and makes your PHP look horrible. This was in Linux/Apache.

Slightly hacky, but it works:

const input = '\text';_x000D_
const output = JSON.stringify(input).replace(/((^")|("$))/g, "").trim();_x000D_
_x000D_
console.log({ input, output });_x000D_
// { input: '\text', output: '\\text' }

Well, the only way I can think of doing everything you want is pretty ugly. First perform an AJAX call to retrieve the Javascript file contents. When this completes you can check the status code to decide if this was successful or not. Then take the responseText from the xhr object and wrap it in a try/catch, dynamically create a script tag, and for IE you can set the text property of the script tag to the JS text, in all other browsers you should be able to append a text node with the contents to script tag. If there's any code that expects a script tag to actually contain the src location of the file, this won't work, but it should be fine for most situations.

Use one way flow syntax property binding:

<div [innerHTML]="comment"></div>

From angular docs: "Angular recognizes the value as unsafe and automatically sanitizes it, which removes the <script> tag but keeps safe content such as the <b> element."

Any searching with select statement yield you only object name, where search keyword contains. Easiest and efficient way is get script of procedure/function and then search in generated text file, I also follows this technique :) So you are exact pinpoint.

TryGetValue is slightly faster, because FindEntry will only be called once.

How much faster? It depends on the dataset at hand. When you call the Contains method, Dictionary does an internal search to find its index. If it returns true, you need another index search to get the actual value. When you use TryGetValue, it searches only once for the index and if found, it assigns the value to your variable.

FYI: It's not actually catching an error.

It's calling:

public bool TryGetValue(TKey key, out TValue value)
{
    int index = this.FindEntry(key);
    if (index >= 0)
    {
        value = this.entries[index].value;
        return true;
    }
    value = default(TValue);
    return false;
}

ContainsKey is this:

public bool ContainsKey(TKey key)
{
    return (this.FindEntry(key) >= 0);
}

To get value, use:

$.each($('input'),function(i,val){
    if($(this).attr("type")=="hidden"){
        var valueOfHidFiled=$(this).val();
        alert(valueOfHidFiled);
    }
});

or:

var valueOfHidFiled=$('input[type=hidden]').val();
alert(valueOfHidFiled);

To set value, use:

$('input[type=hidden]').attr('value',newValue);

git remote update && git status 

Found this on the answer to Check if pull needed in Git

git remote update to bring your remote refs up to date. Then you can do one of several things, such as:

1. git status -uno will tell you whether the branch you are tracking is ahead, behind or has diverged. If it says nothing, the local and remote are the same.

2. git show-branch *master will show you the commits in all of the branches whose names end in master (eg master and origin/master).

If you use -v with git remote update you can see which branches got updated, so you don't really need any further commands.

I had the same issues but nothing worked. What I did was I added this to the selector:

-webkit-appearance: none;
-moz-appearance: none;
appearance: none;

Also i find another solution which work for me. In our legacy spring project we use this method for give our users possibilities to use this own configurations:

<bean id="appUserProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
    <property name="ignoreResourceNotFound" value="false"/>
    <property name="locations">
        <list>
            <value>file:./conf/user.properties</value>
        </list>
    </property>
</bean>

And in our code to access this properties need write something like that:

@Value("#{appUserProperties.userProperty}")
private String userProperty

And if a situation arises when you need to add a new property but right now you don't want to add it in production user config it very fast become a hell when you need to patch all your test contexts or your application will be fail on startup.

To handle this problem you can use the next syntax to add a default value:

@Value("#{appUserProperties.get('userProperty')?:'default value'}")
private String userProperty

It was a real discovery for me.

Make the file accessible to the Authenticated Users group. Right click your virtual directory and give the group read/write access to Authenticated Users.

I faced issue on windows 10 machine.

This depends on what content do you have. You need to initialize your requestMessage.Content property with new HttpContent. For example:

...
// Add request body
if (isPostRequest)
{
    requestMessage.Content = new ByteArrayContent(content);
}
...

where content is your encoded content. You also should include correct Content-type header.

UPDATE:

Oh, it can be even nicer (from this answer):

requestMessage.Content = new StringContent("{\"name\":\"John Doe\",\"age\":33}", Encoding.UTF8, "application/json");

If you wish to render a html file, use:

response.sendfile('index.html');

Then you remove:

app.set('view engine', 'html');

Put your *.html in the views directory, or serve a public directory as static dir and put the index.html in the public dir.

eg:

// .vscode/settings.json in workspace

{
  "files.associations": {
    "*Container.js": "javascriptreact",
    "**/components/*/*.js": "javascriptreact",
    "**/config/routes.js": "javascriptreact"
  }
}

You just put them in __init__.py.

So with test/classes.py being:

class A(object): pass
class B(object): pass

... and test/__init__.py being:

from classes import *

class Helper(object): pass

You can import test and have access to A, B and Helper

>>> import test
>>> test.A
<class 'test.classes.A'>
>>> test.B
<class 'test.classes.B'>
>>> test.Helper
<class 'test.Helper'>

Actually they are the same. LEFT OUTER JOIN is same as LEFT JOIN and RIGHT OUTER JOIN is same as RIGHT JOIN. It is more informative way to compare from INNER Join.

See this Wikipedia article for details.

In Clean Code: A Handbook of Agile Software Craftsmanship there is an explicit recommendation against the usage of this prefix:

You also don't need to prefix member variables with m_ anymore. Your classes and functions should be small enough that you don't need them.

There is also an example (C# code) of this:

Bad practice:

public class Part
{
    private String m_dsc; // The textual description

    void SetName(string name)
    {
        m_dsc = name;
    }
}

Good practice:

public class Part
{
    private String description;

    void SetDescription(string description)
    {
        this.description = description;
    }
}

We count with language constructs to refer to member variables in the case of explicitly ambiguity (i.e., description member and description parameter): this.

Here is my solution for 5.1. I needed someone to click a "Like" button on a post, get redirected to login, then return to the original page. If they were already logged in, the href of the "Like" button was intercepted with JavaScript and turned into an AJAX request.

The button is something like <a href="/like/931">Like This Post!</a>. /like/931 is handled by a LikeController that requires the auth middleware.

In the Authenticate middleware (the handle() function), add something like this at the start:

    if(!str_contains($request->session()->previousUrl(), "/auth/login")) {
        $request->session()->put('redirectURL', $request->session()->previousUrl());
        $request->session()->save();
    }

Change /auth/login to whatever your URL is for logging in. This code saves the original page's URL in the session unless the URL is the login URL. This is required because it appears as though this middleware gets called twice. I am not sure why or if that's true. But if you don't check for that conditional, it will be equal to the correct original page, and then somehow get chanced to /auth/login. There is probably a more elegant way to do this.

Then, in the LikeController or whatever controller you have that handles the URL for the button pushed on the original page:

//some code here that adds a like to the database
//...
return redirect($request->session()->get('redirectURL'));

This method is super simple, doesn't require overriding any existing functions, and works great. It is possible there is some easier way for Laravel to do this, but I am not sure what it is. Using the intended() function doesn't work in my case because the LikeController needed to also know what the previous URL was to redirect back to it. Essentially two levels of redirection backwards.

User.objects.filter(username='tom', groups__name='admin').exists()

That query will inform you user : "tom" whether belong to group "admin " or not

Best way to solve this until a fix is available (if a fix comes) is to force IE compatibility mode on the user.

Use <META http-equiv="X-UA-Compatible" content="IE=9"> ideally in the masterpage so all pages in your site get the workaround.

1. Install PAR::Packer. Example for *nix:

   sudo cpan -i PAR::Packer

   For Strawberry Perl for Windows or for ActivePerl and MSVC installed:

   cpan -i PAR::Packer

2. Pack it with pp. It will create an executable named "example" or "example.exe" on Windows.

   pp -o example example.pl

This would work only on the OS where it was built.

P.S. It is really hard to find a Unix clone without Perl. Did you mean Windows?

Check it out in this demo fiddle, go ahead and change the dropdown or default values in the code.

Setting the passenger.Title with a value that equals to a title.Value should work.

View:

<select [(ngModel)]="passenger.Title">
    <option *ngFor="let title of titleArray" [value]="title.Value">
      {{title.Text}}
    </option>
</select>

TypeScript used:

class Passenger {
  constructor(public Title: string) { };
}
class ValueAndText {
  constructor(public Value: string, public Text: string) { }
}

...
export class AppComponent {
    passenger: Passenger = new Passenger("Lord");

    titleArray: ValueAndText[] = [new ValueAndText("Mister", "Mister-Text"),
                                  new ValueAndText("Lord", "Lord-Text")];

}

This works in Python 2.x.

For Python 3 look in the docs:

import urllib.request

with urllib.request.urlopen("http://www.python.org") as url:
    s = url.read()
    # I'm guessing this would output the html source code ?
    print(s)

Not answering your question specifically, but isn't that something that should be handled by the presentation layer of your application. Doing it the way you describe creates extra processing on the database end as well as adding extra network traffic (assuming the database exists on a different machine than the application), for something that could be easily computed on the application side, with more rich date processing libraries, as well as being more language agnostic, especially in the case of your first example which contains the abbreviated month name. Anyway the answers others give you should point you in the right direction if you still decide to go this route.

One more way for square matrix. No numpy, nor itertools, use (effective) in-place elements exchange.

def transpose(m):
    for i in range(1, len(m)):
        for j in range(i):
            m[i][j], m[j][i] = m[j][i], m[i][j]

We need to remember that the {% endif %} comes after the {% else %}.

So this is an example:

{% if someTest %}
     <p> Something is True </p>
{% else %}
     <p> Something is False </p>
{% endif %}

Tables work differently; sometimes counter-intuitively.

The solution is to use width on the table cells instead of max-width.

Although it may sound like in that case the cells won't shrink below the given width, they will actually.
with no restrictions on c, if you give the table a width of 70px, the widths of a, b and c will come out as 16, 42 and 12 pixels, respectively.
With a table width of 400 pixels, they behave like you say you expect in your grid above.
Only when you try to give the table too small a size (smaller than a.min+b.min+the content of C) will it fail: then the table itself will be wider than specified.

I made a snippet based on your fiddle, in which I removed all the borders and paddings and border-spacing, so you can measure the widths more accurately.

table {_x000D_
  width: 70px;_x000D_
}_x000D_
_x000D_

}_x000D_
_x000D_
.c {}

<table>_x000D_
  <tr>_x000D_
    <td class="a">A</td>_x000D_

On Windows it's holding down Alt while box selecting. Once you have your selection then attempt your edit.

Actually, there is one that works flawlessly:

display: flex; flex-direction: column;

as long as you can live with supporting only IE10 and up

.container {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
    background: #ddd;_x000D_
    width: 15em;_x000D_
}_x000D_
_x000D_
.square {_x000D_
    margin: 15px;_x000D_
    height: 3em;_x000D_
    background: yellow;_x000D_
}

<div class="container">_x000D_
    <div class="square"></div>_x000D_
    <div class="square"></div>_x000D_
    <div class="square"></div>_x000D_

In my case encoding of gitignore file was problematic, check if it is UTF-8

When you remake account password make shure it's 8-20 characters include numbers and special characters like ##/* characters like this then verify new password and re enter exact same and should solve the issues with the password verification

Is Perl easily available to you?

$ perl -n -e 'if ($. == 7) { print; exit(0); }'

Obviously substitute whatever number you want for 7.

You need the following permissions in your manifest file:

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

Then you can use the following in your activity class:

WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE); 
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);

Use the following to check if it's enabled or not

boolean wifiEnabled = wifiManager.isWifiEnabled()

You'll find a nice tutorial on the subject on this site.

Make sure that you have trim the selected value before you assigning.

//Model

public class SelectType
{
    public string Text { get; set; }
    public string Value { get; set; }
}

//Controller

var types = new List<SelectType>();
types.Add(new SelectType() { Value =  0, Text = "Select a Type" });
types.Add(new SelectType() { Value =  1, Text = "Family Trust" });
types.Add(new SelectType() { Value =  2, Text = "Unit Trust"});
ViewBag.PartialTypes = types;

//View

@Html.DropDownListFor(m => m.PartialType, new SelectList(ViewBag.PartialTypes, "Value", "Text"), new { id = "Type" })

chunks = [data[100*i:100*(i+1)] for i in range(len(data)/100 + 1)]

This is equivalent to the accepted answer. For example, shortening to batches of 10 for readability:

data = range(35)
print [data[x:x+10] for x in xrange(0, len(data), 10)]
print [data[10*i:10*(i+1)] for i in range(len(data)/10 + 1)]

Outputs:

[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]

I had a similar issue with pods. Basically trying to run my UI tests, Xcode complained about missing pods. Solution to this was much simpler than any described above:

1. go to project file (main not a target)
2. click on the "Info" tab (most left)
3. set proper pod configuration for UI tests target ("Configurations" section right under "Deployment Target")

Working!

I found it in a thread: https://github.com/CocoaPods/CocoaPods/issues/2695

Sounds a bit like a bug for cocoa pods but I can see reasons why it might be tricky case.

Might be a little late to the game here, but I just discovered this fantastic jQuery plugin https://github.com/mkdynamic/jquery-popupwindow. It basically uses an onUnload callback event, so it basically listens out for the closing of the child window, and will perform any necessary stuff at that point. SO there's really no need to write any JS in the child window to pass back to the parent.

If you are using macOS Sierra and the file doesn't exists, run

mysql --help or mysql --help | grep my.cnf

to see the possible locations and loading/reading sequence of my.cnf for mysql then create my.cnf file in one of the suggested directories then add the following line

[mysqld] sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

You can sudo touch /{preferred-path}/my.cnf then edit the file to add sql mode by

sudo nano /{preferred-path}/my.cnf

Then restart mysql, voilaah you are good to go. happy coding

I've used Adam's answer for years now. That said, that there are some cases where it wasn't behaving as I expected:

1. branches that contained the word "master" were ignored, e.g. "notmaster" or "masterful", rather than only the master branch
2. branches that contained the word "dev" were ignored, e.g. "dev-test", rather than only the dev branch
3. deleting branches that are reachable from the HEAD of the current branch (that is, not necessarily master)
4. in detached HEAD state, deleting every branch reachable from the current commit

1 & 2 were straightforward to address, with just a change to the regex. 3 depends on the context of what you want (i.e. only delete branches that haven't been merged into master or against your current branch). 4 has the potential to be disastrous (although recoverable with git reflog), if you unintentionally ran this in detached HEAD state.

Finally, I wanted this to all be in a one-liner that didn't require a separate (Bash|Ruby|Python) script.

TL;DR

Create a git alias "sweep" that accepts an optional -f flag:

git config --global alias.sweep '!git branch --merged $([[ $1 != "-f" ]] \
&& git rev-parse master) | egrep -v "(^\*|^\s*(master|develop)$)" \
| xargs git branch -d'

and invoke it with:

git sweep

or:

git sweep -f

The long, detailed answer

It was easiest for me to create an example git repo with some branches and commits to test the correct behavior:

Create a new git repo with a single commit

mkdir sweep-test && cd sweep-test && git init
echo "hello" > hello
git add . && git commit -am "initial commit"

Create some new branches

git branch foo && git branch bar && git branch develop && git branch notmaster && git branch masterful
git branch --list

  bar
  develop
  foo
* master
  masterful
  notmaster

Desired behavior: select all merged branches except: master, develop or current

The original regex misses the branches "masterful" and "notmaster" :

git checkout foo
git branch --merged | egrep -v "(^\*|master|dev)"

  bar

With the updated regex (which now excludes "develop" rather than "dev"):

git branch --merged | egrep -v "(^\*|^\s*(master|develop)$)"

bar
masterful
notmaster

Switch to branch foo, make a new commit, then checkout a new branch, foobar, based on foo:

echo "foo" > foo
git add . && git commit -am "foo"
git checkout -b foobar
echo "foobar" > foobar
git add . && git commit -am "foobar"

My current branch is foobar, and if I re-run the above command to list the branches I want to delete, the branch "foo" is included even though it hasn't been merged into master:

git branch --merged | egrep -v "(^\*|^\s*(master|develop)$)"

  bar
  foo
  masterful
  notmaster

However, if I run the same command on master, the branch "foo" is not included:

git checkout master && git branch --merged | egrep -v "(^\*|^\s*(master|develop)$)"

  bar
  masterful
  notmaster

And this is simply because git branch --merged defaults to the HEAD of the current branch if not otherwise specified. At least for my workflow, I don't want to delete local branches unless they've been merged to master, so I prefer the following variant using git rev-parse:

git checkout foobar
git branch --merged $(git rev-parse master) | egrep -v "(^\*|^\s*(master|develop)$)"

  bar
  masterful
  notmaster

Detached HEAD state

Relying on the default behavior of git branch --merged has even more significant consequences in detached HEAD state:

git checkout foobar
git checkout HEAD~0
git branch --merged | egrep -v "(^\*|^\s*(master|develop)$)"

  bar
  foo
  foobar
  masterful
  notmaster

This would have deleted the branch I was just on, "foobar" along with "foo", which is almost certainly not the desired outcome. With our revised command, however:

git branch --merged $(git rev-parse master) | egrep -v "(^\*|^\s*(master|develop)$)"

  bar
  masterful
  notmaster

One line, including the actual delete

git branch --merged $(git rev-parse master) | egrep -v "(^\*|^\s*(master|develop)$)" | xargs git branch -d

All wrapped up into a git alias "sweep":

git config --global alias.sweep '!git branch --merged $([[ $1 != "-f" ]] \
&& git rev-parse master) | egrep -v "(^\*|^\s*(master|develop)$)" \

The alias accepts an optional -f flag. The default behavior is to only delete branches that have been merged into master, but the -f flag will delete branches that have been merged into the current branch.

git sweep

Deleted branch bar (was 9a56952).
Deleted branch masterful (was 9a56952).
Deleted branch notmaster (was 9a56952).

git sweep -f

Deleted branch foo (was 2cea1ab).

You have to pass the arguments in the terminal in order to store them in 'argv'. This variable holds the arguments you pass to your Python script when you run it. It later unpacks the arguments and store them in different variables you specify in the program e.g.

script, first, second = argv
print "Your file is:", script
print "Your first entry is:", first
print "Your second entry is:" second

Then in your command line you have to run your code like this,

$python ex14.py Hamburger Pizza

Your output will look like this:

Your file is: ex14.py
Your first entry is: Hamburger
Your second entry is: Pizza

Branches are made of wood and grow from the trunk of the tree. Tags are made of paper (derivative of wood) and hang like Christmas Ornaments from various places in the tree.

Your project is the tree, and your feature that will be added to the project will grow on a branch. The answer is branch.

use this

style:

<style type="text/css">
    .defaultLabel_on { color:#0F0; }
    .defaultLabel_off { color:#CCC; }
</style>

html:

javascript:

function defaultLabelClean() {
    inputs = document.getElementsByTagName("input");
    for (var i = 0; i < inputs.length; i++)  {
        if (inputs[i].value == inputs[i].getAttribute("innerLabel")) {
            inputs[i].value = '';
        }

good work

There is a modern port for this Turbo C graphics interface, it's called WinBGIM, which emulates BGI graphics under MinGW/GCC.

I haven't it tried but it looks promising. For example initgraph creates a window, and from this point you can draw into that window using the good old functions, at the end closegraph deletes the window. It also has some more advanced extensions (eg. mouse handling and double buffering).

When I first moved from DOS programming to Windows I didn't have internet, and I begged for something simple like this. But at the end I had to learn how to create windows and how to handle events and use device contexts from the offline help of the Windows SDK.

Is there a reason you are not doing something like:

public class IPGUI extends JFrame implements ActionListener 
{
    private static JPanel contentPane;

    private JButton btnConvertDocuments;
    private JButton btnExtractImages;
    private JButton btnParseRIDValues;
    private JButton btnParseImageInfo;

    public IPGUI() 
    {
        ...

        btnConvertDocuments = new JButton("1. Convert Documents");

        ...

        btnExtractImages = new JButton("2. Extract Images");

        ...

        //etc.
    }

    public void actionPerformed(ActionEvent event) 
    {
        String command = event.getActionCommand();

        if (command.equals("w"))
        {
            FileConverter fc = new FileConverter();
            btnConvertDocuments.setEnabled( false );
        }
        else if (command.equals("x"))
        {
            ImageExtractor ie = new ImageExtractor();
            btnExtractImages.setEnabled( false );
        }

        // etc.
    }    
}

The if statement with your disabling code won't get called unless you keep calling the IPGUI constructor.

Given that this is a schedule of jobs, I suspect that at some point you are going to sort them into a proposed order of execution.

If that's the case, then a topological sort implementation may in any case detect cycles. UNIX tsort certainly does. I think it is likely that it is therefore more efficient to detect cycles at the same time as tsorting, rather than in a separate step.

So the question might become, "how do I most efficiently tsort", rather than "how do I most efficiently detect loops". To which the answer is probably "use a library", but failing that the following Wikipedia article:

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

has the pseudo-code for one algorithm, and a brief description of another from Tarjan. Both have O(|V| + |E|) time complexity.

I think you're conflating the use of the response object with that of the request.

The response object is for sending the HTTP response back to the calling client, whereas you are wanting to access the body of the request. See this answer which provides some guidance.

If you are using valid JSON and are POSTing it with Content-Type: application/json, then you can use the bodyParser middleware to parse the request body and place the result in request.body of your route.

For earlier versions of Express (< 4)

var express = require('express')
  , app = express.createServer();

app.use(express.bodyParser());

app.post('/', function(request, response){
  console.log(request.body);      // your JSON
  response.send(request.body);    // echo the result back
});

app.listen(3000);

Test along the lines of:

$ curl -d '{"MyKey":"My Value"}' -H "Content-Type: application/json" http://127.0.0.1:3000/
{"MyKey":"My Value"}

Updated for Express 4+

Body parser was split out into it's own npm package after v4, requires a separate install npm install body-parser

var express = require('express')
  , bodyParser = require('body-parser');

var app = express();

app.use(bodyParser.json());

app.post('/', function(request, response){
  console.log(request.body);      // your JSON
   response.send(request.body);    // echo the result back
});

app.listen(3000);

Update for Express 4.16+

Starting with release 4.16.0, a new express.json() middleware is available.

var express = require('express');

var app = express();

app.use(express.json());

app.post('/', function(request, response){
  console.log(request.body);      // your JSON
   response.send(request.body);    // echo the result back
});

app.listen(3000);

You can use enum and refer that enum in annotation field

The error you are getting i.e. "unexpected token o" is because json is expected but object is obtained while parsing. That "o" is the first letter of word "object".

Here is how i calculate age given a birth date and current date.

select case 
            when cast(getdate() as date) = cast(dateadd(year, (datediff(year, '1996-09-09', getdate())), '1996-09-09') as date)
                then dateDiff(yyyy,'1996-09-09',dateadd(year, 0, getdate()))
            else dateDiff(yyyy,'1996-09-09',dateadd(year, -1, getdate()))
        end as MemberAge
go

You could send yourself an email an look in the email header (In Outlook: Open the mail, View->Options, there is 'Internet headers)

Try this,

this.props.router.push('/foo')

warning works for versions prior to v4

and

this.props.history.push('/foo')

for v4 and above

See if the plugin has a 'skip' configuration parameter. Nearly all do. if it does, just add it to a declaration in the child:

<plugin>
   <groupId>group</groupId>
   <artifactId>artifact</artifactId>
   <configuration>
     <skip>true</skip>
   </configuration>
</plugin>

If not, then use:

Usage:

"something -- something_else".split(" -- ") 

An UnauthorizedAccessException exception is thrown when the operating system denies access because of an I/O error or a security error.

If you are attempting to access a file or registry key, make sure it is not read-only.

If you want to avoid the yellow flicker until your css is applied slap a transition on that bad boy like so:

input:-webkit-autofill {
    -webkit-box-shadow: 0 0 0 1000px white inset !important;
    transition: background-color 10s ease-in-out 0s;
}

In my experience all the files which i have downloaded from internet,gmail are stored in

/sdcard/download

on ics

/sdcard/Download

You can access it using

Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);

One more approach to reading a file that I happen to like is referred to variously as variable notation or variable syntax and involves simply enclosing a filespec within curly braces preceded by a dollar sign, to wit:

$content = ${C:file.txt}

This notation may be used as either an L-value or an R-value; thus, you could just as easily write to a file with something like this:

 ${D:\path\to\file.txt} = $content

Another handy use is that you can modify a file in place without a temporary file and without sub-expressions, for example:

${C:file.txt} = ${C:file.txt} | select -skip 1

I became fascinated by this notation initially because it was very difficult to find out anything about it! Even the PowerShell 2.0 specification mentions it only once showing just one line using it--but with no explanation or details of use at all. I have subsequently found this blog entry on PowerShell variables that gives some good insights.

One final note on using this: you must use a drive designation, i.e. ${drive:filespec} as I have done in all the examples above. Without the drive (e.g. ${file.txt}) it does not work. No restrictions on the filespec on that drive: it may be absolute or relative.

What I believe user2087510 meant was:

name = 'something'
name = name.replace("'", "\\'")

I have also used this with success.

i was looking for a way to implement descriptions in typescript enums (v2.5) and this pattern worked for me:

export enum PriceTypes {
    Undefined = 0,
    UndefinedDescription = 'Undefined' as any,
    UserEntered = 1,
    UserEnteredDescription = 'User Entered' as any,
    GeneratedFromTrade = 2,
    GeneratedFromTradeDescription = 'Generated From Trade' as any,
    GeneratedFromFreeze = 3,
    GeneratedFromFreezeDescription = 'Generated Rom Freeze' as any
}

...

    GetDescription(e: any, id: number): string {
        return e[e[id].toString() + "Description"];
    }
    getPriceTypeDescription(price: IPricePoint): string {
        return this.GetDescription(PriceTypes, price.priceType);
    }

While Niemeyer's answer is a more correct answer to the question, you could also do the following:

<div>
  <input data-bind="value: VMA.name" />
</div>

<div>
  <input data-bind="value: VMB.name" />
</div>

<script type="text/javascript">
  var viewModels = {
     VMA: {name: ko.observable("Bob")},
     VMB: {name: ko.observable("Ted")}
  };

  ko.applyBindings(viewModels);
</script>

This means you don't have to specify the DOM element, and you can even bind multiple models to the same element, like this:

<div>
  <input data-bind="value: VMA.name() + ' and ' + VMB.name()" />
</div>

Use whatever navigation key you want to get inside the parentheses, then you can use either yi( or yi) to copy everything within the matching parens. This also works with square brackets (e.g. yi]) and curly braces. In addition to y, you can also delete or change text (e.g. ci), di]).

I tried this with double and single-quotes and it appears to work there as well. For your data, I do:

write (*, '(a)') 'Computed solution coefficients:'

Move cursor to the C, then type yi'. Move the cursor to a blank line, hit p, and get

Computed solution coefficients:

As CMS noted, this works for visual mode selection as well - just use vi), vi}, vi', etc.

Just use String.value of like below;

  private static void h() {

        String helloWorld = "helloWorld";
        System.out.println(helloWorld);

        char [] charArr = helloWorld.toCharArray();

        System.out.println(String.valueOf(charArr));
    }

ESLint 2.x experimentally supports ObjectRestSpread syntax, you can enable it by adding the following to your .eslintrc: docs

"parserOptions": {
  "ecmaVersion": 6,
  "ecmaFeatures": {
    "experimentalObjectRestSpread": true
  }
},

ESLint 1.x doesn't natively support the spread operator, one way to get around this is using the babel-eslint parser. The latest installation and usage instructions are on the project readme.

I use one main Javascript function that I had found at Mozilla Developer Network site https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications, along with another function with AJAX and changed according to my needs. It receives a document element id regarding the place in my html code where I want to write the file size.

<Javascript>

function updateSize(elementId) {
    var nBytes = 0,
    oFiles = document.getElementById(elementId).files,
    nFiles = oFiles.length;

    for (var nFileId = 0; nFileId < nFiles; nFileId++) {
        nBytes += oFiles[nFileId].size;
    }
    var sOutput = nBytes + " bytes";
    // optional code for multiples approximation
    for (var aMultiples = ["K", "M", "G", "T", "P", "E", "Z", "Y"], nMultiple = 0, nApprox = nBytes / 1024; nApprox > 1; nApprox /= 1024, nMultiple++) {
        sOutput = " (" + nApprox.toFixed(3) + aMultiples[nMultiple] + ")";
    }

    return sOutput;
}
</Javascript>

<HTML>
<input type="file" id="inputFileUpload" onchange="uploadFuncWithAJAX(this.value);" size="25">

<Javascript with XMLHttpRequest>
document.getElementById('spanFileSizeText').innerHTML=updateSize("inputFileUpload");

You need to add your source files with git add or the GUI equivalent so that Git will begin tracking them.

Use git status to see what Git thinks about the files in any given directory.

Use vars(module) then filter out anything that isn't a function using inspect.isfunction:

import inspect
import my_module

my_module_functions = [f for _, f in vars(my_module).values() if inspect.isfunction(f)]

The advantage of vars over dir or inspect.getmembers is that it returns the functions in the order they were defined instead of sorted alphabetically.

Also, this will include functions that are imported by my_module, if you want to filter those out to get only functions that are defined in my_module, see my question Get all defined functions in Python module.

I wrote this SP to do just what you want, however, you need to use dynamic sql.

Example:

What I have found is that simply wrapping code in the componentDidMount or componentDidUpdate with a setTimeout with a time of 0 milliseconds ensures that the browser DOM has been updated with the React changes before executing the setTimeout function.

Like this:

componentDidMount() {
    setTimeout(() => {
        $("myclass") //  $ is available here
    }, 0)
}

This puts the anonymous function on the JS Event Queue to run immediately after the currently running React stack frame has completed.

The IF/THEN/ELSE construct you are using is only valid in stored procedures and functions. Your query will need to be restructured because you can't use the IF() function to control the flow of the WHERE clause like this.

The IF() function that can be used in queries is primarily meant to be used in the SELECT portion of the query for selecting different data based on certain conditions, not so much to be used in the WHERE portion of the query:

SELECT IF(JQ.COURSE_ID=0, 'Some Result If True', 'Some Result If False'), OTHER_COLUMNS
FROM ...
WHERE ...

from file2 import * is making copies. You want to do this:

import file2
print file2.foo
print file2.SomeClass()

onCreate(Bundle) is called when the activity first starts up. You can use it to perform one-time initialization such as creating the user interface. onCreate() takes one parameter that is either null or some state information previously saved by the onSaveInstanceState.

I suppose you want form based authentication using deployment descriptors and j_security_check.

You can also do this in JSF by just using the same predefinied field names j_username and j_password as demonstrated in the tutorial.

E.g.

<form action="j_security_check" method="post">
    <h:outputLabel for="j_username" value="Username" />
    <h:inputText id="j_username" />
    <br />
    <h:outputLabel for="j_password" value="Password" />
    <h:inputSecret id="j_password" />
    <br />
    <h:commandButton value="Login" />
</form>

You could do lazy loading in the User getter to check if the User is already logged in and if not, then check if the Principal is present in the request and if so, then get the User associated with j_username.

public class Auth {

    private User user; // The JPA entity.

    @EJB
    private UserService userService;

    public User getUser() {
        if (user == null) {
            Principal principal = FacesContext.getCurrentInstance().getExternalContext().getUserPrincipal();
            if (principal != null) {
                user = userService.find(principal.getName()); // Find User by j_username.
            }
        }
        return user;
    }

}

The User is obviously accessible in JSF EL by #{auth.user}.

To logout do a HttpServletRequest#logout() (and set User to null!). You can get a handle of the HttpServletRequest in JSF by ExternalContext#getRequest(). You can also just invalidate the session altogether.

public String logout() {
    FacesContext.getCurrentInstance().getExternalContext().invalidateSession();
    return "login?faces-redirect=true";
}

For the remnant (defining users, roles and constraints in deployment descriptor and realm), just follow the Java EE 6 tutorial and the servletcontainer documentation the usual way.

Update: you can also use the new Servlet 3.0 HttpServletRequest#login() to do a programmatic login instead of using j_security_check which may not per-se be reachable by a dispatcher in some servletcontainers. In this case you can use a fullworthy JSF form and a bean with username and password properties and a login method which look like this:

<h:form>
    <h:outputLabel for="username" value="Username" />
    <h:inputText id="username" value="#{auth.username}" required="true" />
    <h:message for="username" />
    <br />
    <h:outputLabel for="password" value="Password" />
    <h:inputSecret id="password" value="#{auth.password}" required="true" />
    <h:message for="password" />
    <br />
    <h:commandButton value="Login" action="#{auth.login}" />
    <h:messages globalOnly="true" />
</h:form>

And this view scoped managed bean which also remembers the initially requested page:

@ManagedBean
@ViewScoped
public class Auth {

    private String username;
    private String password;
    private String originalURL;

    @PostConstruct
    public void init() {
        ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
        originalURL = (String) externalContext.getRequestMap().get(RequestDispatcher.FORWARD_REQUEST_URI);

        if (originalURL == null) {
            originalURL = externalContext.getRequestContextPath() + "/home.xhtml";
        } else {
            String originalQuery = (String) externalContext.getRequestMap().get(RequestDispatcher.FORWARD_QUERY_STRING);

            if (originalQuery != null) {
                originalURL += "?" + originalQuery;
            }
        }
    }

    @EJB
    private UserService userService;

    public void login() throws IOException {
        FacesContext context = FacesContext.getCurrentInstance();
        ExternalContext externalContext = context.getExternalContext();
        HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();

        try {
            request.login(username, password);
            User user = userService.find(username, password);
            externalContext.getSessionMap().put("user", user);
            externalContext.redirect(originalURL);
        } catch (ServletException e) {
            // Handle unknown username/password in request.login().
            context.addMessage(null, new FacesMessage("Unknown login"));
        }
    }

    public void logout() throws IOException {
        ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
        externalContext.invalidateSession();
        externalContext.redirect(externalContext.getRequestContextPath() + "/login.xhtml");
    }

    // Getters/setters for username and password.
}

This way the User is accessible in JSF EL by #{user}.

Take a look at docopt. It is a formal standard for documenting (and automatically parsing) command line arguments.

For example...

Usage:
  my_program command --option <argument>
  my_program [<optional-argument>]
  my_program --another-option=<with-argument>
  my_program (--either-that-option | <or-this-argument>)
  my_program <repeating-argument> <repeating-argument>...

It's Hebrew for "double colon".

This helped in my case:

options: {
    responsive: true,
    scales: {
        yAxes: [{
            display: true,
            ticks: {
                min:0,
                max:100
            }
        }]
    }
}

To check all the applications listening on all ports, there is command:

netstat -ntpl

as per @Jon Skeet 's comment, you should use a XmlReader only if your file is very big. Here's how to use it. Assuming you have a Book class

public class Book {
    public string Title {get; set;}
    public string Author {get; set;}
}

you can read the XML file line by line with a small memory footprint, like this:

public static class XmlHelper {
    public static IEnumerable<Book> StreamBooks(string uri) {
        using (XmlReader reader = XmlReader.Create(uri)) {
            string title = null;
            string author = null;

            reader.MoveToContent();
            while (reader.Read()) {
                if (reader.NodeType == XmlNodeType.Element
                    && reader.Name == "Book") {
                    while (reader.Read()) {
                        if (reader.NodeType == XmlNodeType.Element &&
                            reader.Name == "Title") {
                            title = reader.ReadString();
                            break;
                        }
                    }
                    while (reader.Read()) {
                        if (reader.NodeType == XmlNodeType.Element &&
                            reader.Name == "Author") {
                            author =reader.ReadString();
                            break;
                        }
                    }
                    yield return new Book() {Title = title, Author = author};
                }
            }       
        }
    }

Example of usage:

string uri = @"c:\test.xml"; // your big XML file

foreach (var book in XmlHelper.StreamBooks(uri)) {
    Console.WriteLine("Title, Author: {0}, {1}", book.Title, book.Author);  
}

try {
                    query = URLEncoder.encode(query, "utf-8");
                } catch (UnsupportedEncodingException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

A simple function drawing a circle on the middle of your window frame, using a multiplicator percentage

/// CGFloat is a multiplicator from self.view.frame.width
func drawCircle(withMultiplicator coefficient: CGFloat) {

    let radius = self.view.frame.width / 2 * coefficient

    let circlePath = UIBezierPath(arcCenter: self.view.center, radius: radius, startAngle: CGFloat(0), endAngle:CGFloat(Double.pi * 2), clockwise: true)
    let shapeLayer = CAShapeLayer()
    shapeLayer.path = circlePath.cgPath

    //change the fill color
    shapeLayer.fillColor = UIColor.clear.cgColor
    shapeLayer.strokeColor = UIColor.darkGray.cgColor
    shapeLayer.lineWidth = 2.0

    view.layer.addSublayer(shapeLayer)
}

Use Mark Longair's answer, but make sure to use the HTTPS link to the repository:

git remote set-url origin https://github.com/my_user_name/my_repo.git

You can use then git push origin master.

Assuming Unix file type and you only want the last newline this works.

sed -e '${/^$/d}'

It will not work on multiple newlines...

* Works only if the last line is a blank line.

The error Event the onerror handler receives is a simple event not containing such information:

If the user agent was required to fail the WebSocket connection or the WebSocket connection is closed with prejudice, fire a simple event named error at the WebSocket object.

You may have better luck listening for the close event, which is a CloseEvent and indeed has a CloseEvent.code property containing a numerical code according to RFC 6455 11.7 and a CloseEvent.reason string property.

Please note however, that CloseEvent.code (and CloseEvent.reason) are limited in such a way that network probing and other security issues are avoided.

In case you are using JQuery 2.x then please add the following in the

This worked for me.

PHP 7.3 Application IIS on Windows Server 2012 R2

This was a two step process for me.

1) Enable the WCF Services - with a server restart

2) Add a FASTCGI Module Mapping

1)

Go to Server Manager > Add roles and features Select your server from the server pool Go to Features > WCF Services I selected all categories then installed

2)

Go to IIS > selected the site In center pane select Handler Mappings Right hand pane select Add Module Mappings

Within the edit window:

Request path: *.php

Module: FastCgimodule

Executable: I browsed to the php-cgi.exe inside my PHP folder

Name: PHP7.3

Now that I think about it. There might be a way to add this handler mapping inside the web-config so if you migrate your site to another server you don't have to add this mapping over and over.

EDIT: Here it is. Add this to the section of the web-config.

<add name="PHP-FastCGI" verb="*" 
  path="*.php" 
  modules="FastCgiModule"
  scriptProcessor="c:\php\php-cgi.exe" 
  resourceType="Either" />

Use a List<String>, such as an ArrayList<String>. It's dynamically growable, unlike arrays (see: Effective Java 2nd Edition, Item 25: Prefer lists to arrays).

import java.util.*;
//....

List<String> list = new ArrayList<String>();
list.add("1");
list.add("2");
list.add("3");
System.out.println(list); // prints "[1, 2, 3]"

If you insist on using arrays, you can use java.util.Arrays.copyOf to allocate a bigger array to accomodate the additional element. This is really not the best solution, though.

static <T> T[] append(T[] arr, T element) {
    final int N = arr.length;
    arr = Arrays.copyOf(arr, N + 1);
    arr[N] = element;
    return arr;
}

String[] arr = { "1", "2", "3" };
System.out.println(Arrays.toString(arr)); // prints "[1, 2, 3]"
arr = append(arr, "4");
System.out.println(Arrays.toString(arr)); // prints "[1, 2, 3, 4]"

This is O(N) per append. ArrayList, on the other hand, has O(1) amortized cost per operation.

It worth to say that discussed topic is documented in RFC 2397 - The "data" URL scheme (https://tools.ietf.org/html/rfc2397)

Because of this PHP has a native way to handle such data - "data: stream wrapper" (http://php.net/manual/en/wrappers.data.php)

So you can easily manipulate your data with PHP streams:

$data = 'data:image/gif;base64,R0lGODlhEAAOALMAAOazToeHh0tLS/7LZv/0jvb29t/f3//Ub//ge8WSLf/rhf/3kdbW1mxsbP//mf///yH5BAAAAAAALAAAAAAQAA4AAARe8L1Ekyky67QZ1hLnjM5UUde0ECwLJoExKcppV0aCcGCmTIHEIUEqjgaORCMxIC6e0CcguWw6aFjsVMkkIr7g77ZKPJjPZqIyd7sJAgVGoEGv2xsBxqNgYPj/gAwXEQA7';

$source = fopen($data, 'r');
$destination = fopen('image.gif', 'w');

stream_copy_to_stream($source, $destination);

fclose($source);
fclose($destination);

Yes. Youtube API is the best resource for this.

There are 3 way to embed a video:

• IFrame embeds using <iframe> tags
• IFrame embeds using the IFrame Player API
• AS3 (and AS2*) object embeds DEPRECATED

I think you are looking for the second one of them:

IFrame embeds using the IFrame Player API

The HTML and JavaScript code below shows a simple example that inserts a YouTube player into the page element that has an id value of ytplayer. The onYouTubePlayerAPIReady() function specified here is called automatically when the IFrame Player API code has loaded. This code does not define any player parameters and also does not define other event handlers.

<div id="ytplayer"></div>

<script>
  // Load the IFrame Player API code asynchronously.
  var tag = document.createElement('script');
  tag.src = "https://www.youtube.com/player_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  // Replace the 'ytplayer' element with an <iframe> and
  // YouTube player after the API code downloads.
  var player;
  function onYouTubePlayerAPIReady() {
    player = new YT.Player('ytplayer', {
      height: '390',
      width: '640',
      videoId: 'M7lc1UVf-VE'
    });
  }
</script>

Here are some instructions where you may take a look when starting using the API.

An embed example without using iframe is to use <object> tag:

<object width="640" height="360">
    <param name="movie" value="http://www.youtube.com/embed/yt-video-id?html5=1&amp;rel=0&amp;hl=en_US&amp;version=3"/
    <param name="allowFullScreen" value="true"/>
    <param name="allowscriptaccess" value="always"/>
    <embed width="640" height="360" src="http://www.youtube.com/embed/yt-video-id?html5=1&amp;rel=0&amp;hl=en_US&amp;version=3" class="youtube-player" type="text/html" allowscriptaccess="always" allowfullscreen="true"/>
</object>

(replace yt-video-id with your video id)

JSFIDDLE

function lastRow(column){
  var sheet = SpreadsheetApp.getActiveSpreadsheet();
  var lastRow = sheet.getLastRow();
  var lastRowRange=sheet.getRange(column+startRow);
  return lastRowRange.getValue();
}

no hard coding.

I had this one a while back, and the answer isn't necessarily what you'd expect. This error message often crops up when your connection string is wrong.

At a guess, you'll need something like this:

<connectionStrings>
    <add name="hublisherEntities" connectionString="Data Source=localhost;Initial Catalog=hublisher;Integrated Security=True;" providerName="System.Data.SqlClient" />
</connectionStrings>
<entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
        <parameters>
            <parameter value="Data Source=localhost;Initial Catalog=hublisher;Integrated Security=True" />
        </parameters>
    </defaultConnectionFactory>
</entityFramework>

What's happening is that it's looking for a data source in the wrong place; Entity Framework specifies it slightly differently. If you post your connection string and EF config then we can check.

I have a similar problem importing those libs. I am using Anaconda Navigator 1.8.2 with Spyder 3.2.8.

My code is the following:

import matplotlib.pyplot as plt
import tensorflow as tf
import numpy as np
import math

#from tf.keras.models import Sequential  # This does not work!
from tensorflow.python.keras.models import Sequential
from tensorflow.python.keras.layers import InputLayer, Input
from tensorflow.python.keras.layers import Reshape, MaxPooling2D
from tensorflow.python.keras.layers import Conv2D, Dense, Flatten

I get the following error:

from tensorflow.python.keras.models import Sequential

ModuleNotFoundError: No module named 'tensorflow.python.keras'

I solve this erasing tensorflow.python

With this code I solve the error:

import matplotlib.pyplot as plt
import tensorflow as tf
import numpy as np
import math

#from tf.keras.models import Sequential  # This does not work!
from keras.models import Sequential
from keras.layers import InputLayer, Input

In Java, the optimizations are usually done at the JVM level. At runtime, the JVM perform some "complicated" analysis to determine which methods to inline. It can be aggressive in inlining, and the Hotspot JVM actually can inline non-final methods.

The java compilers almost never inline any method call (the JVM does all of that at runtime). They do inline compile time constants (e.g. final static primitive values). But not methods.

Performance test for in_array vs array_intersect:

$a1 = array(2,4,8,11,12,13,14,15,16,17,18,19,20);

$a2 = array(3,20);

$intersect_times = array();
$in_array_times = array();
for($j = 0; $j < 10; $j++)
{
    /***** TEST ONE array_intersect *******/
    $t = microtime(true);
    for($i = 0; $i < 100000; $i++)
    {
        $x = array_intersect($a1,$a2);
        $x = empty($x);
    }
    $intersect_times[] = microtime(true) - $t;


    /***** TEST TWO in_array *******/
    $t2 = microtime(true);
    for($i = 0; $i < 100000; $i++)
    {
        $x = false;
        foreach($a2 as $v){
            if(in_array($v,$a1))
            {
                $x = true;
                break;
            }
        }
    }
    $in_array_times[] = microtime(true) - $t2;
}

echo '<hr><br>'.implode('<br>',$intersect_times).'<br>array_intersect avg: '.(array_sum($intersect_times) / count($intersect_times));
echo '<hr><br>'.implode('<br>',$in_array_times).'<br>in_array avg: '.(array_sum($in_array_times) / count($in_array_times));

Use text-center instead of center-block.

Or use center-block on the span element (I did the column wider so you can see the alignment better):

<div class="row">
   <div class="col-xs-10" style="background-color:#123;">
      <span class="center-block" style="width:100px; background-color:#ccc;">abc</span>
   </div>
</div>

If you want to avoid a DirectoryNotFoundException you will need to ensure that the directory of the file does indeed exist. File.Exists accomplishes this. Another way would be to utilize the Path and Directory utility classes like so:

string file = @"C:\subfolder\test.txt";
if (Directory.Exists(Path.GetDirectoryName(file)))
{
    File.Delete(file);
}

Another way to work this around is to add this into your module package.json scripts section

"preinstall": "npm install {Packages You depend on}"

what this will does is, it will install all packages needed by the module and you won't get that error.

It is an old question but if you need to generalize this to a higher than 2 dimension arrays, here is the solution than can be easily generalized:

np.einsum('ij->ij', a[a[:,1].argsort(),:])

This is an overkill for two dimensions and a[a[:,1].argsort()] would be enough per @steve's answer, however that answer cannot be generalized to higher dimensions. You can find an example of 3D array in this question.

Output:

[[7 0 5]
 [9 2 3]
 [4 5 6]]

Well I agree with Ryan Conrad on how to do it in eclipse, have you ensured you have changed your manifest.xml?

 <uses-sdk android:minSdkVersion="3" />
 <uses-sdk android:targetSdkVersion="8" />

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

The easiest way to solve this problem is to use a command line. Type this command

rm -R .git/

OR

rm -rf .git/

Content Type for MOV videos are video/quicktime in my case. Adding type="video/mp4" to MOV video file solved issue in my case.

<video width="400" controls Autoplay=autoplay>
  <source src="D:/mov1.mov" type="video/mp4">
</video>

In this state:

The thread is reading and processing rows for a SELECT statement, and sending data to the client.

Because operations occurring during this this state tend to perform large amounts of disk access (reads).

That's why it takes more time to complete and so is the longest-running state over the lifetime of a given query.

Depending on where you need that and how to access the object there are different ways to do it.

For example: just typecast it

$object =  (object) $yourArray;

However, the most compatible one is using a utility method (not yet part of PHP) that implements standard PHP casting based on a string that specifies the type (or by ignoring it just de-referencing the value):

/**
 * dereference a value and optionally setting its type
 *
 * @param mixed $mixed
 * @param null  $type (optional)
 *
 * @return mixed $mixed set as $type
 */
function rettype($mixed, $type = NULL) {
    $type === NULL || settype($mixed, $type);
    return $mixed;
}

The usage example in your case (Online Demo):

$yourArray = Array('status' => 'Figure A. ...');

echo rettype($yourArray, 'object')->status; // prints "Figure A. ..."
