It's easy to change your existing NSLogs to display line number and class from which they are called. Add one line of code to your prefix file:

#define NSLog(__FORMAT__, ...) NSLog((@"%s [Line %d] " __FORMAT__), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__)

Why do you have the brackets around digit? It should be

NSLog("%@", digit);

You're also missing an = in the first line...

NSString *digit = [[sender titlelabel] text];

subprocess.Popen takes a cwd argument to set the Current Working Directory; you'll also want to escape your backslashes ('d:\\test\\local'), or use r'd:\test\local' so that the backslashes aren't interpreted as escape sequences by Python. The way you have it written, the \t part will be translated to a tab.

So, your new line should look like:

subprocess.Popen(r'c:\mytool\tool.exe', cwd=r'd:\test\local')

To use your Python script path as cwd, import os and define cwd using this:

os.path.dirname(os.path.realpath(__file__)) 

For someone that might find useful, you can use layout_constraintDimensionRatio im any child view inside a ConstraintLayout and we can define the Height or Width a ratio of the other dimension( at least one must be 0dp either width or heigh) example

 <ImageView
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:src="@drawable/top_image"
        app:layout_constraintDimensionRatio="16:9"        
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"/>

in this case the aspect ratio it's 16:9 app:layout_constraintDimensionRatio="16:9" you can find more info HERE

$customer_id = get_current_user_id();
print get_user_meta( $customer_id, 'billing_first_name', true );

See here: Git doesn't clone all branches on subsequent clones?

If you really want this by pulling branches instead of push --mirror, you can have a look here:

"fetch --all" in a git bare repository doesn't synchronize local branches to the remote ones

This answer provides detailed steps on how to achieve that relatively easily:

For anyone else who might run into this, my issue was that I was making a column of type string and trying to make it ->unsigned() when I meant for it to be an integer.

In Python 3 there is valid reason to use print over sys.stdout.write, but this reason can also be turned into a reason to use sys.stdout.write instead.

This reason is that, now print is a function in Python 3, you can override this. So you can use print everywhere in a simple script and decide those print statements need to write to stderr instead. You can now just redefine the print function, you could even change the print function global by changing it using the builtins module. Off course with file.write you can specify what file is, but with overwriting print you can also redefine the line separator, or argument separator.

The other way around is. Maybe you are absolutely certain you write to stdout, but also know you are going to change print to something else, you can decide to use sys.stdout.write, and use print for error log or something else.

So, what you use depends on how you intend to use it. print is more flexible, but that can be a reason to use and to not use it. I would still opt for flexibility instead, and choose print. Another reason to use print instead is familiarity. More people will now what you mean by print and less know sys.stdout.write.

On Vista with virtualization on, the file is here. Note that the AppData folder is hidden. Either show hidden folders, or go straight to it by typing %AppData% in the address bar of Windows Explorer.

C:\Users\[user]\AppData\Roaming\Notepad++\shortcuts.xml

For those still struggling with the error, make sure that you also import ReactiveFormsModule in your component 's module.ts file

meaning that you will import your ReactiveFormsModule in your app.module.ts and also in your mycomponent.module.ts file

Use match_parent and gravity to set the TextView text to right, like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

    <TextView android:text="TextView" android:id="@+id/textView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="right">
    </TextView>

</LinearLayout>

you can do it with _pull.

_.pull(obj["subTopics"] , {"subTopicId":2, "number":32});

Use JQuery or so, as CSS is a general misconception (the countless questions and discussions here about simple design goals show that).

It is not possible with CSS to do what you seem to wish: image shall have width of 100%, but if this width results in a height that is too large, a max-height shall apply - and of course the correct proportions shall be preserved.

One issue with your ContentLoader is that internally it operates sequentially. A better pattern is to parallelize the work and then sychronize at the end, so we get

public class PageViewModel : IHandle<SomeMessage>
{
   ...

   public async void Handle(SomeMessage message)
   {
      ShowLoadingAnimation();

      // makes UI very laggy, but still not dead
      await this.contentLoader.LoadContentAsync(); 

      HideLoadingAnimation();   
   }
}

public class ContentLoader 
{
    public async Task LoadContentAsync()
    {
        var tasks = new List<Task>();
        tasks.Add(DoCpuBoundWorkAsync());
        tasks.Add(DoIoBoundWorkAsync());
        tasks.Add(DoCpuBoundWorkAsync());
        tasks.Add(DoSomeOtherWorkAsync());

        await Task.WhenAll(tasks).ConfigureAwait(false);
    }
}

Obviously, this doesn't work if any of the tasks require data from other earlier tasks, but should give you better overall throughput for most scenarios.

Take a look on life cycle of Activity

Where

***onCreate()***

Called when the activity is first created. This is where you should do all of your normal static set up: create views, bind data to lists, etc. This method also provides you with a Bundle containing the activity's previously frozen state, if there was one. Always followed by onStart().

***onStart()***

Called when the activity is becoming visible to the user. Followed by onResume() if the activity comes to the foreground, or onStop() if it becomes hidden.

And you can write your simple class to take a look when these methods call

public class TestActivity extends Activity {
    /** Called when the activity is first created. */

    private final static String TAG = "TestActivity";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Log.i(TAG, "On Create .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onDestroy()
    */
    @Override
    protected void onDestroy() { 
        super.onDestroy();
        Log.i(TAG, "On Destroy .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onPause()
    */
    @Override
    protected void onPause() { 
        super.onPause();
        Log.i(TAG, "On Pause .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onRestart()
    */
    @Override
    protected void onRestart() {
        super.onRestart();
        Log.i(TAG, "On Restart .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onResume()
    */
    @Override
    protected void onResume() {
        super.onResume();
        Log.i(TAG, "On Resume .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onStart()
    */
    @Override
    protected void onStart() {
        super.onStart();
        Log.i(TAG, "On Start .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onStop()
    */
    @Override
    protected void onStop() {
        super.onStop();
        Log.i(TAG, "On Stop .....");
    }
}

Hope this will clear your confusion.

The answer to this question has changed over the years. The current answer is here at the top, followed by the various answers over the years in chronological order:

Current Answer

You can use fs.existsSync():

const fs = require("fs"); // Or `import fs from "fs";` with ESM
if (fs.existsSync(path)) {
    // Do something
}

It was deprecated for several years, but no longer is. From the docs:

Note that fs.exists() is deprecated, but fs.existsSync() is not. (The callback parameter to fs.exists() accepts parameters that are inconsistent with other Node.js callbacks. fs.existsSync() does not use a callback.)

You've specifically asked for a synchronous check, but if you can use an asynchronous check instead (usually best with I/O), use fs.promises.access if you're using async functions or fs.access (since exists is deprecated) if not:

In an async function:

try {
    await fs.promises.access("somefile");
    // The check succeeded
} catch (error) {
    // The check failed
}

Or with a callback:

fs.access("somefile", error => {
    if (!error) {
        // The check succeeded
    } else {
        // The check failed
    }
});

Historical Answers

Here are the historical answers in chronological order:

• Original answer from 2010
  (stat/statSync or lstat/lstatSync)
• Update September 2012
  (exists/existsSync)
• Update February 2015
  (Noting impending deprecation of exists/existsSync, so we're probably back to stat/statSync or lstat/lstatSync)
• Update December 2015
  (There's also fs.access(path, fs.F_OK, function(){}) / fs.accessSync(path, fs.F_OK), but note that if the file/directory doesn't exist, it's an error; docs for fs.stat recommend using fs.access if you need to check for existence without opening)
• Update December 2016
  fs.exists() is still deprecated but fs.existsSync() is no longer deprecated. So you can safely use it now.

Original answer from 2010:

You can use statSync or lstatSync (docs link), which give you an fs.Stats object. In general, if a synchronous version of a function is available, it will have the same name as the async version with Sync at the end. So statSync is the synchronous version of stat; lstatSync is the synchronous version of lstat, etc.

lstatSync tells you both whether something exists, and if so, whether it's a file or a directory (or in some file systems, a symbolic link, block device, character device, etc.), e.g. if you need to know if it exists and is a directory:

var fs = require('fs');
try {
    // Query the entry
    stats = fs.lstatSync('/the/path');

    // Is it a directory?
    if (stats.isDirectory()) {
        // Yes it is
    }
}
catch (e) {
    // ...
}

...and similarly, if it's a file, there's isFile; if it's a block device, there's isBlockDevice, etc., etc. Note the try/catch; it throws an error if the entry doesn't exist at all.

If you don't care what the entry is and only want to know whether it exists, you can use path.existsSync (or with latest, fs.existsSync) as noted by user618408:

var path = require('path');
if (path.existsSync("/the/path")) { // or fs.existsSync
    // ...
}

It doesn't require a try/catch but gives you no information about what the thing is, just that it's there. path.existsSync was deprecated long ago.

Side note: You've expressly asked how to check synchronously, so I've used the xyzSync versions of the functions above. But wherever possible, with I/O, it really is best to avoid synchronous calls. Calls into the I/O subsystem take significant time from a CPU's point of view. Note how easy it is to call lstat rather than lstatSync:

// Is it a directory?
lstat('/the/path', function(err, stats) {
    if (!err && stats.isDirectory()) {
        // Yes it is
    }
});

But if you need the synchronous version, it's there.

Update September 2012

The below answer from a couple of years ago is now a bit out of date. The current way is to use fs.existsSync to do a synchronous check for file/directory existence (or of course fs.exists for an asynchronous check), rather than the path versions below.

Example:

var fs = require('fs');

if (fs.existsSync(path)) {
    // Do something
}

// Or

fs.exists(path, function(exists) {
    if (exists) {
        // Do something
    }
});

Update February 2015

And here we are in 2015 and the Node docs now say that fs.existsSync (and fs.exists) "will be deprecated". (Because the Node folks think it's dumb to check whether something exists before opening it, which it is; but that's not the only reason for checking whether something exists!)

So we're probably back to the various stat methods... Until/unless this changes yet again, of course.

Update December 2015

Don't know how long it's been there, but there's also fs.access(path, fs.F_OK, ...) / fs.accessSync(path, fs.F_OK). And at least as of October 2016, the fs.stat documentation recommends using fs.access to do existence checks ("To check if a file exists without manipulating it afterwards, fs.access() is recommended."). But note that the access not being available is considered an error, so this would probably be best if you're expecting the file to be accessible:

var fs = require('fs');

try {
    fs.accessSync(path, fs.F_OK);
    // Do something
} catch (e) {
    // It isn't accessible
}

// Or

fs.access(path, fs.F_OK, function(err) {
    if (!err) {
        // Do something
    } else {
        // It isn't accessible
    }
});

Update December 2016

You can use fs.existsSync():

if (fs.existsSync(path)) {
    // Do something
}

It was deprecated for several years, but no longer is. From the docs:

Note that fs.exists() is deprecated, but fs.existsSync() is not. (The callback parameter to fs.exists() accepts parameters that are inconsistent with other Node.js callbacks. fs.existsSync() does not use a callback.)

I'm going to test adding the no-store tag to our site to see if this makes a difference to browser caching (Chrome has sometimes been caching the pages). I also found this article very useful on documentation on how and why caching works and will look at ETag's next if the no-store is not reliable:

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

OpenID and OAuth are each HTTP-based protocols for authentication and/or authorization. Both are intended to allow users to perform actions without giving authentication credentials or blanket permissions to clients or third parties. While they are similar, and there are proposed standards to use them both together, they are separate protocols.

OpenID is intended for federated authentication. A client accepts an identity assertion from any provider (although clients are free to whitelist or blacklist providers).

OAuth is intended for delegated authorization. A client registers with a provider, which provides authorization tokens which it will accept to perform actions on the user's behalf.

OAuth is currently better suited for authorization, because further interactions after authentication are built into the protocol, but both protocols are evolving. OpenID and its extensions could be used for authorization, and OAuth can be used for authentication, which can be thought of as a no-op authorization.

If you don't want to use a library, this should cover most/all of the same form element types.

function serialize(form) {
  if (!form || !form.elements) return;

  var serial = [], i, j, first;
  var add = function (name, value) {
    serial.push(encodeURIComponent(name) + '=' + encodeURIComponent(value));
  }

  var elems = form.elements;
  for (i = 0; i < elems.length; i += 1, first = false) {
    if (elems[i].name.length > 0) { /* don't include unnamed elements */
      switch (elems[i].type) {
        case 'select-one': first = true;
        case 'select-multiple':
          for (j = 0; j < elems[i].options.length; j += 1)
            if (elems[i].options[j].selected) {
              add(elems[i].name, elems[i].options[j].value);
              if (first) break; /* stop searching for select-one */
            }
          break;
        case 'checkbox':
        case 'radio': if (!elems[i].checked) break; /* else continue */
        default: add(elems[i].name, elems[i].value); break;
      }
    }
  }

  return serial.join('&');
}

Systemd which now runs in the majority of distros

Step 1:

Find your user defined services mine was at /usr/lib/systemd/system/

Step 2:

Create a text file with your favorite text editor name it whatever_you_want.service

Step 3:

Put following Template to the file whatever_you_want.service

[Unit]
Description=webserver Daemon

[Service]
ExecStart=/usr/bin/java -jar /web/server.jar
User=user

[Install]
WantedBy=multi-user.target

Step 4:

Run your service
as super user

$ systemctl start whatever_you_want.service # starts the service
$ systemctl enable whatever_you_want.service # auto starts the service
$ systemctl disable whatever_you_want.service # stops autostart
$ systemctl stop whatever_you_want.service # stops the service
$ systemctl restart whatever_you_want.service # restarts the service

We had a similar issue. We were trying to GET from:

[RoutePrefix("api/car")]
public class CarController: ApiController{

    [HTTPGet]
    [Route("")]
    public virtual async Task<ActionResult> GetAll(){

    }

}

So we would .GET("/api/car") and this would throw a 405 error.

The CarController.cs file was in the directory /api/car so when we were requesting this api endpoint, IIS would send back an error because it looked like we were trying to access a virtual directory that we were not allowed to.

Option 1: change / rename the directory the controller is in
Option 2: change the route prefix to something that doesn't match the virtual directory.

In short:

• OpenJDK has multiple meanings and can refer to:
  • free and open source implementation of the Java Platform, Standard Edition (Java SE)
  • open source repository — the Java source code aka OpenJDK project
  • prebuilt OpenJDK binaries maintained by Oracle
  • prebuilt OpenJDK binaries maintained by the OpenJDK community
• AdoptOpenJDK — prebuilt OpenJDK binaries maintained by community (open source licensed)

Explanation:

Prebuilt OpenJDK (or distribution) — binaries, built from http://hg.openjdk.java.net/, provided as an archive or installer, offered for various platforms, with a possible support contract.

OpenJDK, the source repository (also called OpenJDK project) - is a Mercurial-based open source repository, hosted at http://hg.openjdk.java.net. The Java source code. The vast majority of Java features (from the VM and the core libraries to the compiler) are based solely on this source repository. Oracle have an alternate fork of this.

OpenJDK, the distribution (see the list of providers below) - is free as in beer and kind of free as in speech, but, you do not get to call Oracle if you have problems with it. There is no support contract. Furthermore, Oracle will only release updates to any OpenJDK (the distribution) version if that release is the most recent Java release, including LTS (long-term support) releases. The day Oracle releases OpenJDK (the distribution) version 12.0, even if there's a security issue with OpenJDK (the distribution) version 11.0, Oracle will not release an update for 11.0. Maintained solely by Oracle.

Some OpenJDK projects - such as OpenJDK 8 and OpenJDK 11 - are maintained by the OpenJDK community and provide releases for some OpenJDK versions for some platforms. The community members have taken responsibility for releasing fixes for security vulnerabilities in these OpenJDK versions.

AdoptOpenJDK, the distribution is very similar to Oracle's OpenJDK distribution (in that it is free, and it is a build produced by compiling the sources from the OpenJDK source repository). AdoptOpenJDK as an entity will not be backporting patches, i.e. there won't be an AdoptOpenJDK 'fork/version' that is materially different from upstream (except for some build script patches for things like Win32 support). Meaning, if members of the community (Oracle or others, but not AdoptOpenJDK as an entity) backport security fixes to updates of OpenJDK LTS versions, then AdoptOpenJDK will provide builds for those. Maintained by OpenJDK community.

OracleJDK - is yet another distribution. Starting with JDK12 there will be no free version of OracleJDK. Oracle's JDK distribution offering is intended for commercial support. You pay for this, but then you get to rely on Oracle for support. Unlike Oracle's OpenJDK offering, OracleJDK comes with longer support for LTS versions. As a developer you can get a free license for personal/development use only of this particular JDK, but that's mostly a red herring, as 'just the binary' is basically the same as the OpenJDK binary. I guess it means you can download security-patched versions of LTS JDKs from Oracle's websites as long as you promise not to use them commercially.

Note. It may be best to call the OpenJDK builds by Oracle the "Oracle OpenJDK builds".

Donald Smith, Java product manager at Oracle writes:

Ideally, we would simply refer to all Oracle JDK builds as the "Oracle JDK", either under the GPL or the commercial license, depending on your situation. However, for historical reasons, while the small remaining differences exist, we will refer to them separately as Oracle’s OpenJDK builds and the Oracle JDK.

_{Free Builds from Source - the distribution source code is publicly available and one can assemble its own build}

_{Free Binary Distributions - the distribution binaries are publicly available for download and usage}

_{Extended Updates - aka LTS (long-term support) - Public Updates beyond the 6-month release lifecycle}

_{Commercial Support - some providers offer extended updates and customer support to paying customers, e.g. Oracle JDK (support details)}

_{Permissive License - the distribution license is non-protective, e.g. Apache 2.0}

Which Java Distribution Should I Use?

In the Sun/Oracle days, it was usually Sun/Oracle producing the proprietary downstream JDK distributions based on OpenJDK sources. Recently, Oracle had decided to do their own proprietary builds only with the commercial support attached. They graciously publish the OpenJDK builds as well on their https://jdk.java.net/ site.

What is happening starting JDK 11 is the shift from single-vendor (Oracle) mindset to the mindset where you select a provider that gives you a distribution for the product, under the conditions you like: platforms they build for, frequency and promptness of releases, how support is structured, etc. If you don't trust any of existing vendors, you can even build OpenJDK yourself.

Each build of OpenJDK is usually made from the same original upstream source repository (OpenJDK “the project”). However each build is quite unique - $free or commercial, branded or unbranded, pure or bundled (e.g., BellSoft Liberica JDK offers bundled JavaFX, which was removed from Oracle builds starting JDK 11).

If no environment (e.g., Linux) and/or license requirement defines specific distribution and if you want the most standard JDK build, then probably the best option is to use OpenJDK by Oracle or AdoptOpenJDK.

Aleksey Shipilev about JDK updates interview by Opsian (published on June 27, 2019)

I'm assuming you mean that you don't care which row is used to obtain the title, id, and commentname values (you have "rob" for all of the rows, but I don't know if that is actually something that would be enforced or not in your data model). If so, then you can use windowing functions to return the first row for a given email address:

select
    id,
    title,
    email,
    commentname

from
(
select 
    *, 
    row_number() over (partition by email order by id) as RowNbr 

from YourTable
) source

where RowNbr = 1

You can specify the connection timeout within the SQL connection string, when you connect to the database, like so:

"Data Source=localhost;Initial Catalog=database;Connect Timeout=15"

On the server level, use MSSQLMS to view the server properties, and on the Connections page you can specify the default query timeout.

I'm not quite sure that queries keep on running after the client connection has closed. Queries should not take that long either, MSSQL can handle large databases, I've worked with GB's of data on it before. Run a performance profile on the queries, prehaps some well-placed indexes could speed it up, or rewriting the query could too.

Update: According to this list, SQL timeouts happen when waiting for attention acknowledgement from server:

Suppose you execute a command, then the command times out. When this happens the SqlClient driver sends a special 8 byte packet to the server called an attention packet. This tells the server to stop executing the current command. When we send the attention packet, we have to wait for the attention acknowledgement from the server and this can in theory take a long time and time out. You can also send this packet by calling SqlCommand.Cancel on an asynchronous SqlCommand object. This one is a special case where we use a 5 second timeout. In most cases you will never hit this one, the server is usually very responsive to attention packets because these are handled very low in the network layer.

So it seems that after the client connection times out, a signal is sent to the server to cancel the running query too.

Actually, this is the proper way to get what you want, unless you can use MS SQL 2014 (which finally enables custom format strings for date times).

To get yyyymm instead of yyyym, you can use this little trick:

select 
 right('0000' + cast(datepart(year, getdate()) as varchar(4)), 4)
 + right('00' + cast(datepart(month, getdate()) as varchar(2)), 2)

It's faster and more reliable than gettings parts of convert(..., 112).

public class MainActivity extends AppCompatActivity  implements View.OnClickListener{

    Button b1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        b1=(Button)findViewById(R.id.button);
        b1.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        Toast.makeText(getApplicationContext(),"Button is Working",Toast.LENGTH_LONG).show();
    }

}

The reason it has no effect is because at the link-time the linker tries to resolve the extern definition (in your case extern int f()). It doesn't matter if it finds it in the same file or a different file, as long as it is found.

Hope this answers your question.

This esc behavior is IE only by the way. Instead of using jQuery use good old javascript for creating the element and it works.

var element = document.createElement('input');
element.type = 'text';
element.value = 100;
document.getElementsByTagName('body')[0].appendChild(element);

http://jsfiddle.net/gGrf9/

If you want to extend this functionality to other browsers then I would use jQuery's data object to store the default. Then set it when user presses escape.

//store default value for all elements on page. set new default on blur
$('input').each( function() {
    $(this).data('default', $(this).val());
    $(this).blur( function() { $(this).data('default', $(this).val()); });
});

$('input').keyup( function(e) {
    if (e.keyCode == 27) { $(this).val($(this).data('default')); }
});

self.navigationItem.title=@"Extras";

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

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

This answer is just useful to understand how you can make delay using JQuery delay function.

Imagine you have an alert and you want to set the alert text then show the alert and after a few seconds hide it.

Here is the simple solution:

$(".alert-element").html("I'm the alert text").fadeIn(500).delay(5000).fadeOut(1000);

It is completely simple:

1. .html() will change the text of .alert-element
2. .fadeIn(500) will fade in after 500 milliseconds
3. JQuery delay(5000) function will make 5000 milliseconds of delay before calling next function
4. .fadeOut(1000) at the end of the statement will fade out the .alert-element

None of the other solutions worked for me, but this does:

Create your own subclass of UINavigationController, make it implement the UINavigationBarDelegate (no need to manually set the navigation bar's delegate), add a UIViewController extension that defines a method to be called on a back button press, and then implement this method in your UINavigationController subclass:

func navigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool {
    self.topViewController?.methodToBeCalledOnBackButtonPress()
    self.popViewController(animated: true)
    return true
}

TypeScript isn't giving you a gun to shoot yourself in the foot with.

The iterator variable is a string because it is a string, full stop. Observe:

var obj = {};
obj['0'] = 'quote zero quote';
obj[0.0] = 'zero point zero';
obj['[object Object]'] = 'literal string "[object Object]"';
obj[<any>obj] = 'this obj'
obj[<any>undefined] = 'undefined';
obj[<any>"undefined"] = 'the literal string "undefined"';

for(var key in obj) {
    console.log('Type: ' + typeof key);
    console.log(key + ' => ' + obj[key]);
}

How many key/value pairs are in obj now? 6, more or less? No, 3, and all of the keys are strings:

Type: string
0 => zero point zero
Type: string
[object Object] => this obj; 
Type: string
undefined => the literal string "undefined" 

I know the question was on configuration of OpenFileDialog but seeing that Google brought me here i may as well point out that if you are ONLY looking for folders you should be using a FolderBrowserDialog Instead as answered by another SO question below

How to specify path using open file dialog in vb.net?

with this script in file.sh

#!/bin/bash
echo Your container args are: "$@"

and this Dockerfile

FROM ubuntu:14.04
COPY ./file.sh /
ENTRYPOINT ["/file.sh"]

you should be able to:

% docker build -t test .
% docker run test hello world
Your container args are: hello world

svn cp /trunk/ /branch/NEW_Branch

If you have some local changes in trunk then use Rsync to sync changes

rsync -r -v -p --exclude ".svn" /trunk/ /branch/NEW_Branch

java.io.File doesn't represent an open file, it represents a path in the filesystem. Therefore having close method on it doesn't make sense.

Actually, this class was misnamed by the library authors, it should be called something like Path.

I have this sample Java Code:

import java.io.*;
import java.net.*;
import java.nio.charset.StandardCharsets;

public class TestClass {
    public static void main(String[] args) throws IOException {
        ServerSocket socket = new ServerSocket(8081);
        Socket accept = socket.accept();
        InputStream inputStream = accept.getInputStream();

        InputStreamReader inputStreamReader = new InputStreamReader(inputStream, StandardCharsets.UTF_8);
        char readChar;
        while ((readChar = (char) inputStreamReader.read()) != -1) {
            System.out.print(readChar);
        }

        inputStream.close();
        accept.close();
        System.exit(1);
    }
}

and I have this test.html file:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>File Upload!</title>
</head>
<body>
<form method="post" action="http://localhost:8081" enctype="multipart/form-data">
    <input type="file" name="file" id="file">
    <input type="submit">
</form>
</body>
</html>

and finally the file I will be using for testing purposes, named a.dat has the following content:

0x39 0x69 0x65

if you interpret the bytes above as ASCII or UTF-8 characters, they will actually will be representing:

9ie

So let 's run our Java Code, open up test.html in our favorite browser, upload a.dat and submit the form and see what our server receives:

POST / HTTP/1.1
Host: localhost:8081
Connection: keep-alive
Content-Length: 196
Cache-Control: max-age=0

Content-Disposition: form-data; name="file"; filename="a.dat"
Content-Type: application/octet-stream

9ie
------WebKitFormBoundary06f6g54NVbSieT6y--

Well I am not surprised to see the characters 9ie because we told Java to print them treating them as UTF-8 characters. You may as well choose to read them as raw bytes..

Cookie: JSESSIONID=27D0A0637A0449CF65B3CB20F40048AF 

is actually the last HTTP Header here. After that comes the HTTP Body, where meta and contents of the file we uploaded actually can be seen.

Request class doesn't offer a method that would return exactly what you need. But you can easily get it by concatenating results of 2 other methods:

echo (Request::getPathInfo() . (Request::getQueryString() ? ('?' . Request::getQueryString()) : '');

I have been using csvreader.com(paid component) for years, and I have never had a problem. It is solid, small and fast, but you do have to pay for it. You can set the delimiter to whatever you like.

using (CsvReader reader = new CsvReader(s) {
    reader.Settings.Delimiter = ';';
    reader.ReadHeaders();  // if headers on a line by themselves.  Makes reader.Headers[] available
    while (reader.ReadRecord())
        ... use reader.Values[col_i] ...
}

There are commercial products such as ionCube (which I use), source guardian, and Zen Guard.

There are also postings on the net which claim they can reverse engineer the encoded programs. How reliable they are is questionable, since I have never used them.

Note that most of these solutions require an encoder to be installed on their servers. So you may want to make sure your client is comfortable with that.

I believe putty has a maximum number of columns you can specify for the window.

For Windows I personally use Windows PowerShell and set the screen buffer width reasonably high. The column width remains fixed and you can use a horizontal scroll bar to see the data. I had the same problem you're having now.

edit: For remote hosts that you have to SSH into you would use something like plink + Windows PowerShell

HTTPS proxy doesn't make sense because you can't terminate your HTTP connection at the proxy for security reasons. With your trust policy, it might work if the proxy server has a HTTPS port. Your error is caused by connecting to HTTP proxy port with HTTPS.

You can connect through a proxy using SSL tunneling (many people call that proxy) using proxy CONNECT command. However, Java doesn't support newer version of proxy tunneling. In that case, you need to handle the tunneling yourself. You can find sample code here,

http://www.javaworld.com/javaworld/javatips/jw-javatip111.html

EDIT: If you want defeat all the security measures in JSSE, you still need your own TrustManager. Something like this,

 public SSLTunnelSocketFactory(String proxyhost, String proxyport){
      tunnelHost = proxyhost;
      tunnelPort = Integer.parseInt(proxyport);
      dfactory = (SSLSocketFactory)sslContext.getSocketFactory();
 }

 ...

 connection.setSSLSocketFactory( new SSLTunnelSocketFactory( proxyHost, proxyPort ) );
 connection.setDefaultHostnameVerifier( new HostnameVerifier()
 {
    public boolean verify( String arg0, SSLSession arg1 )
    {
        return true;
    }
 }  );

EDIT 2: I just tried my program I wrote a few years ago using SSLTunnelSocketFactory and it doesn't work either. Apparently, Sun introduced a new bug sometime in Java 5. See this bug report,

http://bugs.sun.com/view_bug.do?bug_id=6614957

The good news is that the SSL tunneling bug is fixed so you can just use the default factory. I just tried with a proxy and everything works as expected. See my code,

public class SSLContextTest {

    public static void main(String[] args) {

        System.setProperty("https.proxyHost", "proxy.xxx.com");
        System.setProperty("https.proxyPort", "8888");

        try {

            SSLContext sslContext = SSLContext.getInstance("SSL");

            // set up a TrustManager that trusts everything
            sslContext.init(null, new TrustManager[] { new X509TrustManager() {
                public X509Certificate[] getAcceptedIssuers() {
                    System.out.println("getAcceptedIssuers =============");
                    return null;
                }

                public void checkClientTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkClientTrusted =============");
                }

                public void checkServerTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkServerTrusted =============");
                }
            } }, new SecureRandom());

            HttpsURLConnection.setDefaultSSLSocketFactory(
                    sslContext.getSocketFactory());

            HttpsURLConnection
                    .setDefaultHostnameVerifier(new HostnameVerifier() {
                        public boolean verify(String arg0, SSLSession arg1) {
                            System.out.println("hostnameVerifier =============");
                            return true;
                        }
                    });

            URL url = new URL("https://www.verisign.net");
            URLConnection conn = url.openConnection();
            BufferedReader reader = 
                new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } 
    }
}

This is what I get when I run the program,

checkServerTrusted =============
hostnameVerifier =============
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
......

As you can see, both SSLContext and hostnameVerifier are getting called. HostnameVerifier is only involved when the hostname doesn't match the cert. I used "www.verisign.net" to trigger this.

CURL request by default is GET, you don't have to set any options to make a GET CURL request.

I think this is the most annoying little peculiarity of HTML... That button needs to be of type "button" in order to not submit.

<button type="button">My Button</button>

Update 5-Feb-2019: As per the HTML Living Standard (and also HTML 5 specification):

The missing value default and invalid value default are the Submit Button state.

the easiest way to do this is to wrap your sockets in ObjectInput/OutputStreams and send serialized java objects. you can create classes which contain the relevant data, and then you don't need to worry about the nitty gritty details of handling binary protocols. just make sure that you flush your object streams after you write each object "message".

or you can try this:

string1 = 'Hello \n World'
tmp = string1.split()
string2 = ' '.join(tmp)

Also, does Jenkins delete the artifacts after each build ? (not the archived artifacts, I know I can tell it to delete those)

No, Hudson/Jenkins does not, by itself, clear the workspace after a build. You might have actions in your build process that erase, overwrite, or move build artifacts from where you left them. There is an option in the job configuration, in Advanced Project Options (which must be expanded), called "Clean workspace before build" that will wipe the workspace at the beginning of a new build.

HTML

<select class='form-control'>
    <option *ngFor="let option of options"
    [selected]="option === nrSelect"
    [value]="option">
        {{ option }}
    </option>
</select>

Typescript

nrSelect = 47;
options = [41, 42, 47, 48];

System.Diagnostics.Process.Start("c:\\batchfilename.bat");

this simple line will execute the batch file.

Since I can't post a follow-up to android developer's comment, here's an updated answer for anyone else who needs to programmatically set the selected tab indicator color:

tabLayout.setSelectedTabIndicatorColor(Color.parseColor("#FFFFFF"));

Similarly, for height:

tabLayout.setSelectedTabIndicatorHeight((int) (2 * getResources().getDisplayMetrics().density));

These methods were only recently added to revision 23.0.0 of the Support Library, which is why Soheil Setayeshi's answer uses reflection.

Class.getSimpleName()

Returns the simple name of the underlying class as given in the source code. Returns an empty string if the underlying class is anonymous.

The simple name of an array is the simple name of the component type with "[]" appended. In particular the simple name of an array whose component type is anonymous is "[]".

It is actually stripping the package information from the name, but this is hidden from you.

The problem is that your anonymous object property data-icon has an invalid name. C# properties cannot have dashes in their names. There are two ways you can get around that:

Use an underscore instead of dash (MVC will automatically replace the underscore with a dash in the emitted HTML):

@Html.ActionLink("Edit", "edit", "markets",
      new { id = 1 },
      new {@class="ui-btn-right", data_icon="gear"})

Use the overload that takes in a dictionary:

@Html.ActionLink("Edit", "edit", "markets",
      new { id = 1 },
      new Dictionary<string, object> { { "class", "ui-btn-right" }, { "data-icon", "gear" } });

shared_ptr isn't large enough, nor do its constructor\destructor do enough work for there to be enough overhead from the copy to care about pass by reference vs pass by copy performance.

Explain difference of

extract()

explode()

implode()

Here is another approach to setup gradient and stransparency with CSS. You need to play arround with the parameters a bit though.

background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0%, rgba(0, 0, 0, 0)), color-stop(100%, transparent)),url("gears.jpg"); /* Chrome,Safari4+ */
background-image: -webkit-linear-gradient(top, transparent, transparent),url("gears.jpg"); /* Chrome10+,Safari5.1+ */
background-image:    -moz-linear-gradient(top, transparent, transparent),url("gears.jpg"); /* FF3.6+ */
background-image:     -ms-linear-gradient(top, transparent, transparent),url("gears.jpg"); /* IE10+ */
background-image:      -o-linear-gradient(top, transparent, transparent),url("gears.jpg"); /* Opera 11.10+ */
background-image:         linear-gradient(to bottom, transparent, transparent),url("gears.jpg"); /* W3C */

OP, YOU ARE CORRECT. The else after try/except in Python is ugly. it leads to another flow-control object where none is needed:

try:
    x = blah()
except:
    print "failed at blah()"
else:
    print "just succeeded with blah"

A totally clear equivalent is:

try:
    x = blah()
    print "just succeeded with blah"
except:
    print "failed at blah()"

This is far clearer than an else clause. The else after try/except is not frequently written, so it takes a moment to figure what the implications are.

Just because you CAN do a thing, doesn't mean you SHOULD do a thing.

Lots of features have been added to languages because someone thought it might come in handy. Trouble is, the more features, the less clear and obvious things are because people don't usually use those bells and whistles.

Just my 5 cents here. I have to come along behind and clean up a lot of code written by 1st-year out of college developers who think they're smart and want to write code in some uber-tight, uber-efficient way when that just makes it a mess to try and read / modify later. I vote for readability every day and twice on Sundays.

If I understand correctly, you want to get the String of an Editable object, right? If yes, try using toString().

Another way to check on connection attempts is to look at the server's event log. On my Windows 2008 R2 Enterprise machine I opened the server manager (right-click on Computer and select Manage. Then choose Diagnostics -> Event Viewer -> Windows Logs -> Applcation. You can filter the log to isolate the MSSQLSERVER events. I found a number that looked like this

Login failed for user 'bogus'. The user is not associated with a trusted SQL Server connection. [CLIENT: 10.12.3.126]

Make file executable:

chmod +x file

Find location of perl:

which perl

This should return something like

/bin/perl sometimes /usr/local/bin

Then in the first line of your script add:

#!"path"/perl with path from above e.g.

#!/bin/perl

Then you can execute the file

./file

There may be some issues with the PATH, so you may want to change that as well ...

cin.clear();
fflush(stdin);

This was the only thing that worked for me when reading from console. In every other case it would either read indefinitely due to lack of \n, or something would remain in the buffer.

EDIT: I found out that the previous solution made things worse. THIS one however, works:

cin.getline(temp, STRLEN);
if (cin.fail()) {
    cin.clear();
    cin.ignore(numeric_limits<streamsize>::max(), '\n');
}

Use ampersand to specify the parent selector.

SCSS syntax:

p {
    margin: 2em auto;

    > a {
        color: red;
    }

    &:before {
        content: "";
    }

    &:after {
        content: "* * *";
    }
}

A built-in parameter for saving JPEGs and PNGs is optimize.

 >>> from PIL import Image
 # My image is a 200x374 jpeg that is 102kb large
 >>> foo = Image.open("path\\to\\image.jpg")
 >>> foo.size
  (200,374)
 # I downsize the image with an ANTIALIAS filter (gives the highest quality)
 >>> foo = foo.resize((160,300),Image.ANTIALIAS)
 >>> foo.save("path\\to\\save\\image_scaled.jpg",quality=95)
 # The saved downsized image size is 24.8kb
 >>> foo.save("path\\to\\save\\image_scaled_opt.jpg",optimize=True,quality=95)
 # The saved downsized image size is 22.9kb

The optimize flag will do an extra pass on the image to find a way to reduce its size as much as possible. 1.9kb might not seem like much, but over hundreds/thousands of pictures, it can add up.

Now to try and get it down to 5kb to 10 kb, you can change the quality value in the save options. Using a quality of 85 instead of 95 in this case would yield: Unoptimized: 15.1kb Optimized : 14.3kb Using a quality of 75 (default if argument is left out) would yield: Unoptimized: 11.8kb Optimized : 11.2kb

I prefer quality 85 with optimize because the quality isn't affected much, and the file size is much smaller.

Nice article explaining the basics (does not cover line breaks, however).

A Whole Bunch of Amazing Stuff Pseudo Elements Can Do

If you need to have two inline elements where one breaks into the next line within another element, you can accomplish this by adding a pseudo-element :after with content:'\A' and white-space: pre

HTML

<h3>
    <span class="label">This is the main label</span>
    <span class="secondary-label">secondary label</span>
</h3>

CSS

.label:after {
    content: '\A';
    white-space: pre;
}

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

link for additional resources http://ss64.com/nt/cd.html

For the fastest way $ cd "project"

If it overflows, it goes back to the minimum value and continues from there. If it underflows, it goes back to the maximum value and continues from there.

You can check that beforehand as follows:

public static boolean willAdditionOverflow(int left, int right) {
    if (right < 0 && right != Integer.MIN_VALUE) {
        return willSubtractionOverflow(left, -right);
    } else {
        return (~(left ^ right) & (left ^ (left + right))) < 0;
    }
}

public static boolean willSubtractionOverflow(int left, int right) {
    if (right < 0) {
        return willAdditionOverflow(left, -right);
    } else {
        return ((left ^ right) & (left ^ (left - right))) < 0;
    }
}

(you can substitute int by long to perform the same checks for long)

If you think that this may occur more than often, then consider using a datatype or object which can store larger values, e.g. long or maybe java.math.BigInteger. The last one doesn't overflow, practically, the available JVM memory is the limit.

If you happen to be on Java8 already, then you can make use of the new Math#addExact() and Math#subtractExact() methods which will throw an ArithmeticException on overflow.

public static boolean willAdditionOverflow(int left, int right) {
    try {
        Math.addExact(left, right);
        return false;
    } catch (ArithmeticException e) {
        return true;
    }
}

public static boolean willSubtractionOverflow(int left, int right) {
    try {
        Math.subtractExact(left, right);
        return false;
    } catch (ArithmeticException e) {
        return true;
    }
}

The source code can be found here and here respectively.

Of course, you could also just use them right away instead of hiding them in a boolean utility method.

use this.getClass().getName() to get packageName.className and use this.getClass().getSimpleName() to get only class name

Everything that is business logic belongs in a model, whether it is a database query, calculations, a REST call, etc.

You can have the data access in the model itself, the MVC pattern doesn't restrict you from doing that. You can sugar coat it with services, mappers and what not, but the actual definition of a model is a layer that handles business logic, nothing more, nothing less. It can be a class, a function, or a complete module with a gazillion objects if that's what you want.

It's always easier to have a separate object that actually executes the database queries instead of having them being executed in the model directly: this will especially come in handy when unit testing (because of the easiness of injecting a mock database dependency in your model):

class Database {
   protected $_conn;

   public function __construct($connection) {
       $this->_conn = $connection;
   }

   public function ExecuteObject($sql, $data) {
       // stuff
   }
}

abstract class Model {
   protected $_db;

   public function __construct(Database $db) {
       $this->_db = $db;
   }
}

class User extends Model {
   public function CheckUsername($username) {
       // ...
       $sql = "SELECT Username FROM" . $this->usersTableName . " WHERE ...";
       return $this->_db->ExecuteObject($sql, $data);
   }
}

$db = new Database($conn);
$model = new User($db);
$model->CheckUsername('foo');

Also, in PHP, you rarely need to catch/rethrow exceptions because the backtrace is preserved, especially in a case like your example. Just let the exception be thrown and catch it in the controller instead.

This C# code is to fetch all items from a dynamodb table using BatchGet or CreateBatchGet

        string tablename = "AnyTableName"; //table whose data you want to fetch

        var BatchRead = ABCContext.Context.CreateBatchGet<ABCTable>(  

            new DynamoDBOperationConfig
            {
                OverrideTableName = tablename; 
            });

        foreach(string Id in IdList) // in case you are taking string from input
        {
            Guid objGuid = Guid.Parse(Id); //parsing string to guid
            BatchRead.AddKey(objGuid);
        }

        await BatchRead.ExecuteAsync();
        var result = BatchRead.Results;

// ABCTable is the table modal which is used to create in dynamodb & data you want to fetch

Do this

    <% for(int i = 0; i < allFestivals.size(); i+=1) { %>
        <tr>      
            <td><%=allFestivals.get(i).getFestivalName()%></td>
        </tr>
    <% } %>

Better way is to use c:foreach see link jstl for each

You can use the bitwise operations that do not change the value (^ 0 or ~~) to discard the decimal part, which can be used for rounding. After rounding the number, it is compared to the original value:

function isDecimal(num) {
  return (num ^ 0) !== num;
}

console.log( isDecimal(1) ); // false
console.log( isDecimal(1.5) ); // true
console.log( isDecimal(-0.5) ); // true

I have to make an application which shows the Contact no of the SIM card that is being used in the cell. For that I need to use Telephony Manager class. Can i get details on its usage?

Yes, You have to use Telephony Manager;If at all you not found the contact no. of user; You can get Sim Serial Number of Sim Card and Imei No. of Android Device by using the same Telephony Manager Class...

Add permission:

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

Import:

import android.telephony.TelephonyManager;

Use the below code:

TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

         // get IMEI
         imei = tm.getDeviceId();

         // get SimSerialNumber
         simSerialNumber = tm.getSimSerialNumber();

For the question

How can i run a jar file in command prompt but with arguments

.

To pass arguments to the jar file at the time of execution

java -jar myjar.jar arg1 arg2

In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:

String arg1 = args[0];
String arg2 = args[1];

This problem I solved with the following detail, somehow the android SDK manage installed all the dependencies and necessary files, but forget this `templates` files where is found templates> gradle> wrapper. This set of files is missing.

Path in mac /Users/giogio/Library/Android/sdk/tools/templates

As you probably already know, there's no "foreach"-style loop in C.

Although there are already tons of great macros provided here to work around this, maybe you'll find this macro useful:

// "length" is the length of the array.   
#define each(item, array, length) \
(typeof(*(array)) *p = (array), (item) = *p; p < &((array)[length]); p++, (item) = *p)

...which can be used with for (as in for each (...)).

Advantages of this approach:

• item is declared and incremented within the for statement (just like in Python!).
• Seems to work on any 1-dimensional array
• All variables created in macro (p, item), aren't visible outside the scope of the loop (since they're declared in the for loop header).

Disadvantages:

• Doesn't work for multi-dimensional arrays
• Relies on typeof(), which is a GNU extension, not part of standard C
• Since it declares variables in the for loop header, it only works in C11 or later.

Just to save you some time, here's how you could test it:

typedef struct {
    double x;
    double y;
} Point;

int main(void) {
    double some_nums[] = {4.2, 4.32, -9.9, 7.0};
    for each (element, some_nums, 4)
        printf("element = %lf\n", element);

    int numbers[] = {4, 2, 99, -3, 54};
    // Just demonstrating it can be used like a normal for loop
    for each (number, numbers, 5) { 
        printf("number = %d\n", number);
        if (number % 2 == 0)
                printf("%d is even.\n", number);
    }

    char* dictionary[] = {"Hello", "World"};
    for each (word, dictionary, 2)
        printf("word = '%s'\n", word);

    Point points[] = {{3.4, 4.2}, {9.9, 6.7}, {-9.8, 7.0}};
    for each (point, points, 3)
        printf("point = (%lf, %lf)\n", point.x, point.y);

    // Neither p, element, number or word are visible outside the scope of
    // their respective for loops. Try to see if these printfs work
    // (they shouldn't):
    // printf("*p = %s", *p);
    // printf("word = %s", word);

    return 0;
}

Seems to work on gcc and clang by default; haven't tested other compilers.

It worked for me:

File file = new File(getApplicationContext().getFilesDir(),"whatever.txt");
    if(file.exists()){
       //Do something
    }
    else{
       //Nothing
     }

There is a package random_word could implement this request very conveniently:

 $ pip install random-word

from random_word import RandomWords
r = RandomWords()

# Return a single random word
r.get_random_word()
# Return list of Random words
r.get_random_words()
# Return Word of the day
r.word_of_the_day()

In Firefox at least, the DOM inspector is telling me that the File input elements have a property called files. You should be able to check its length.

document.getElementById('myFileInput').files.length

inserting data form one table to another table in different DATABASE

insert into DocTypeGroup 
    Select DocGrp_Id,DocGrp_SubId,DocGrp_GroupName,DocGrp_PM,DocGrp_DocType 
    from Opendatasource( 'SQLOLEDB','Data Source=10.132.20.19;UserID=sa;Password=gchaturthi').dbIPFMCI.dbo.DocTypeGroup

I just fixed this problem by adding the following code in header:

    <meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">

this is how i did it:

String[] listAges = getResources().getStringArray(R.array.ages);

        // Creating adapter for spinner
        ArrayAdapter<String> dataAdapter =
                new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, listAges);

        // Drop down layout style - list view with radio button
        dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        // attaching data adapter to spinner
        spinner_age.getBackground().setColorFilter(ContextCompat.getColor(this, R.color.spinner_icon), PorterDuff.Mode.SRC_ATOP);
        spinner_age.setAdapter(dataAdapter);
        spinner_age.setSelection(0);
        spinner_age.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                String item = parent.getItemAtPosition(position).toString();

                if(position > 0){
                    // get spinner value
                    Toast.makeText(parent.getContext(), "Age..." + item, Toast.LENGTH_SHORT).show();
                }else{
                    // show toast select gender
                    Toast.makeText(parent.getContext(), "none" + item, Toast.LENGTH_SHORT).show();
                }
            }
            @Override
            public void onNothingSelected(AdapterView<?> parent) {
            }
        });

What about this, for example when you want to add a <option> element inside a <select>

$('<option/>')
  .val(optionVal)
  .text('some option')
  .appendTo('#mySelect')

You can obviously apply to any element

$('<div/>')
  .css('border-color', red)
  .text('some text')
  .appendTo('#parentDiv')

The following function can be copied to any object to add an XML save function using the System.Xml namespace.

/// <summary>
/// Saves to an xml file
/// </summary>
/// <param name="FileName">File path of the new xml file</param>
public void Save(string FileName)
{
    using (var writer = new System.IO.StreamWriter(FileName))
    {
        var serializer = new XmlSerializer(this.GetType());
        serializer.Serialize(writer, this);
        writer.Flush();
    }
}

To create the object from the saved file, add the following function and replace [ObjectType] with the object type to be created.

/// <summary>
/// Load an object from an xml file
/// </summary>
/// <param name="FileName">Xml file name</param>
/// <returns>The object created from the xml file</returns>
public static [ObjectType] Load(string FileName)
{
    using (var stream = System.IO.File.OpenRead(FileName))
    {
        var serializer = new XmlSerializer(typeof([ObjectType]));
        return serializer.Deserialize(stream) as [ObjectType];
    }
}

if((pswd.length<6 || pswd.length>12) || pswd == ""){
        document.getElementById("passwordloc").innerHTML="character should be between 6-12 characters"; status=false;

} 

else {  
    if(pswd != pswdcnf) {
        document.getElementById("passwordconfirm").innerHTML="password doesnt matched"; status=true;
    } else {
        document.getElementById("passwordconfirm").innerHTML="password  matche";
        document.getElementById("passwordloc").innerHTML = '';
    }

}

Use the alternate value for animation-direction (and you don't need to add any keframes this way).

alternate

The animation should reverse direction each cycle. When playing in reverse, the animation steps are performed backward. In addition, timing functions are also reversed; for example, an ease-in animation is replaced with an ease-out animation when played in reverse. The count to determinate if it is an even or an odd iteration starts at one.

CSS:

.waitingForConnection {
  animation: blinker 1.7s cubic-bezier(.5, 0, 1, 1) infinite alternate;  
}
@keyframes blinker { to { opacity: 0; } }

I've removed the from keyframe. If it's missing, it gets generated from the value you've set for the animated property (opacity in this case) on the element, or if you haven't set it (and you haven't in this case), from the default value (which is 1 for opacity).

And please don't use just the WebKit version. Add the unprefixed one after it as well. If you just want to write less code, use the shorthand.

.waitingForConnection {
  animation: blinker 1.7s cubic-bezier(.5, 0, 1, 1) infinite alternate;  
}
@keyframes blinker { to { opacity: 0; } }

.waitingForConnection2 {
  animation: blinker2 0.6s cubic-bezier(1, 0, 0, 1) infinite alternate;  
}
@keyframes blinker2 { to { opacity: 0; } }

.waitingForConnection3 {
  animation: blinker3 1s ease-in-out infinite alternate;  
}
@keyframes blinker3 { to { opacity: 0; } }

<div class="waitingForConnection">X</div>
<div class="waitingForConnection2">Y</div>
<div class="waitingForConnection3">Z</div>

As everyone else notes there are really only two actual language differences:

• struct defaults to public access and class defaults to private access.
• When inheriting, struct defaults to public inheritance and class defaults to private inheritance. (Ironically, as with so many things in C++, the default is backwards: public inheritance is by far the more common choice, but people rarely declare structs just to save on typing the "public" keyword.

But the real difference in practice is between a class/struct that declares a constructor/destructor and one that doesn't. There are certain guarantees to a "plain-old-data" POD type, that no longer apply once you take over the class's construction. To keep this distinction clear, many people deliberately only use structs for POD types, and, if they are going to add any methods at all, use classes. The difference between the two fragments below is otherwise meaningless:

class X
{
  public:

  // ...
};

struct X
{
  // ...
};

(Incidentally, here's a thread with some good explanations about what "POD type" actually means: What are POD types in C++?)

Here is a complete example showing how to use the ** operator to pass values from a dictionary as keyword arguments.

>>> def f(x=2):
...     print(x)
... 
>>> new_x = {'x': 4}
>>> f()        #    default value x=2
2
>>> f(x=3)     #   explicit value x=3
3
>>> f(**new_x) # dictionary value x=4 
4

You should do something like this:
if !(string?.isEmpty ?? true) { //Not nil nor empty }

Nil coalescing operator checks if the optional is not nil, in case it is not nil it then checks its property, in this case isEmpty. Because this optional can be nil you provide a default value which will be used when your optional is nil.

Considering the previous answers, it is necessary to be careful with globalized characters.

Suppose the name of the file is: "Esdrújula prenda ñame - güena.jpg"

Raw result to download: "Esdrújula prenda ñame - güena.jpg" [Ugly]

HtmlEncode result to download: "Esdr&_250;jula prenda &_241;ame - g&_252;ena.jpg" [Ugly]

UrlEncode result to download: "Esdrújula+prenda+ñame+-+güena.jpg" [OK]

Then, you need almost always to use the UrlEncode over the file name. Moreover, if you set the content-disposition header as direct string, then you need to ensure surround with quotes to avoid browser compatibility issues.

Response.AddHeader("Content-Disposition", $"attachment; filename=\"{HttpUtility.UrlEncode(YourFilename)}\"");

or with class aid:

var cd = new ContentDisposition("attachment") { FileName = HttpUtility.UrlEncode(resultFileName) };
Response.AddHeader("Content-Disposition", cd.ToString());

The System.Net.Mime.ContentDisposition class takes care of quotes.

Depends on. Briefly... If you want load variables on current console and execute you may use source myshellfile.sh on your code. Example:

!#/bin/bash
set -x
echo "This is an example of run another INTO this session."
source my_lib_of_variables_and_functions.sh
echo "The function internal_function() is defined into my lib."
returned_value=internal_function()
echo $this_is_an_internal_variable

set +x

If you just want to execute a file and the only thing intersting for you is the result, you can do:

!#/bin/bash
set -x
./executing_only.sh
sh i_can_execute_this_way_too.sh
bash or_this_way.sh
set +x

I hope helps you. Thanks.

It's working as intended. Your MySQL server has been started with --secure-file-priv option which basically limits from which directories you can load files using LOAD DATA INFILE.

You may use SHOW VARIABLES LIKE "secure_file_priv"; to see the directory that has been configured.

You have two options:

1. Move your file to the directory specified by secure-file-priv.
2. Disable secure-file-priv. This must be removed from startup and cannot be modified dynamically. To do this check your MySQL start up parameters (depending on platform) and my.ini.

Maybe this

$products = $art->products->take($limit)->skip($offset)->get();

With FluidXML you can generate and store an XML document very easily.

$doc = fluidxml();

$doc->add('Album', true)
        ->add('Track', 'Track Title');

$doc->save('album.xml');

Loading a document from a file is equally simple.

$doc = fluidify('album.xml');

$doc->query('//Track')
        ->attr('id', 123);

You need to set oracle to listen on all ip addresses (by default, it listens only to localhost connections.)

Step 1 - Edit listener.ora

This file is located in:

• Windows: %ORACLE_HOME%\network\admin\listener.ora.
• Linux: $ORACLE_HOME/network/admin/listener.ora

Replace localhost with 0.0.0.0

# ...

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
    )
  )

# ...

Step 2 - Restart Oracle services

• Windows: WinKey + r

  services.msc
  

• Linux (CentOs):

  sudo systemctl restart oracle-xe
  

Robustness diagrams are written after use cases and before class diagrams. They help to identify the roles of use case steps. You can use them to ensure your use cases are sufficiently robust to represent usage requirements for the system you're building.

They involve:

1. Actors
2. Use Cases
3. Entities
4. Boundaries
5. Controls

Whereas the Model-View-Controller pattern is used for user interfaces, the Entity-Control-Boundary Pattern (ECB) is used for systems. The following aspects of ECB can be likened to an abstract version of MVC, if that's helpful:

Entities (model)
Objects representing system data, often from the domain model.

Boundaries (view/service collaborator)
Objects that interface with system actors (e.g. a user or external service). Windows, screens and menus are examples of boundaries that interface with users.

Controls (controller)
Objects that mediate between boundaries and entities. These serve as the glue between boundary elements and entity elements, implementing the logic required to manage the various elements and their interactions. It is important to understand that you may decide to implement controllers within your design as something other than objects – many controllers are simple enough to be implemented as a method of an entity or boundary class for example.

Four rules apply to their communication:

1. Actors can only talk to boundary objects.
2. Boundary objects can only talk to controllers and actors.
3. Entity objects can only talk to controllers.
4. Controllers can talk to boundary objects and entity objects, and to other controllers, but not to actors

Communication allowed:

         Entity    Boundary   Control
Entity     X                     X
Boundary                         X
Control    X          X          X

The simplest approach is probably to define one custom enum with just one case that has a String attached to it:

enum MyError: ErrorType {
    case runtimeError(String)
}

Or, as of Swift 4:

enum MyError: Error {
    case runtimeError(String)
}

Example usage would be something like:

func someFunction() throws {
    throw MyError.runtimeError("some message")
}
do {
    try someFunction()
} catch MyError.runtimeError(let errorMessage) {
    print(errorMessage)
}

If you wish to use existing Error types, the most general one would be an NSError, and you could make a factory method to create and throw one with a custom message.

Something like:

if(divisor == 0) {
  throw new ArithmeticException("Division by zero!");
}

You can simply press Ctrl+F5 instead of F5 to run the built code. Then it will prompt you to press any key to continue. Or you can use this line -> system("pause"); at the end of the code to make it wait until you press any key.

However, if you use the above line, system("pause"); and press Ctrl+F5 to run, it will prompt you twice!

I was looking for the same answer to this question and after much head scratching this is the answer I came up with:

#Python 3.4.3 with Pygame
import pygame

pygame.init()
pygame.display.set_caption('Crash!')
window = pygame.display.set_mode((300, 300))


# Draw Once
Rectplace = pygame.draw.rect(window, (255, 0, 0),(100, 100, 100, 100))
pygame.display.update()
# Main Loop
while True:
    # Mouse position and button clicking.
    pos = pygame.mouse.get_pos()
    pressed1, pressed2, pressed3 = pygame.mouse.get_pressed()
    # Check if the rect collided with the mouse pos
    # and if the left mouse button was pressed.
    if Rectplace.collidepoint(pos) and pressed1:
        print("You have opened a chest!")
    # Quit pygame.
            for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit(1)

Per the Express (Version 4+) docs, you can use:

res.status(400);
res.send('None shall pass');

http://expressjs.com/4x/api.html#res.status

<=3.8

res.statusCode = 401;
res.send('None shall pass');

It is posible. My android device version is 4.0.4 and android.os.Build.VERSION.SDK_INT is 15

I have 3 spinners

Spinner c_fruit=(Spinner) findViewById(R.id.fruits);
Spinner c_vegetable=(Spinner) findViewById(R.id.vegetables);
Spinner c_beverage=(Spinner) findViewById(R.id.beverages);

And also I have a Async-Tack class.

Here is my spinner loading code

RequestSend reqs_fruit = new RequestSend(this);
reqs_fruit.where="Get_fruit_List";
reqs_fruit.title="Loading fruit";
reqs_fruit.execute();

RequestSend reqs_vegetable = new RequestSend(this);
reqs_vegetable.where="Get_vegetable_List";
reqs_vegetable.title="Loading vegetable";
reqs_vegetable.execute();

RequestSend reqs_beverage = new RequestSend(this);
reqs_beverage.where="Get_beverage_List";
reqs_beverage.title="Loading beverage";
reqs_beverage.execute();

This is working perfectly. One by one my spinners loaded. I didn't user executeOnExecutor.

Here is my Async-task class

public class RequestSend  extends AsyncTask<String, String, String > {

    private ProgressDialog dialog = null;
    public Spinner spin;
    public String where;
    public String title;
    Context con;
    Activity activity;      
    String[] items;

    public RequestSend(Context activityContext) {
        con = activityContext;
        dialog = new ProgressDialog(activityContext);
        this.activity = activityContext;
    }

    @Override
    protected void onPostExecute(String result) {
        try {
            ArrayAdapter<String> adapter = new ArrayAdapter<String> (activity, android.R.layout.simple_spinner_item, items);       
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            spin.setAdapter(adapter);
        } catch (NullPointerException e) {
            Toast.makeText(activity, "Can not load list. Check your connection", Toast.LENGTH_LONG).show();
            e.printStackTrace();
        } catch (Exception e)  {
            Toast.makeText(activity, "Can not load list. Check your connection", Toast.LENGTH_LONG).show();
            e.printStackTrace();
        }
        super.onPostExecute(result);

        if (dialog != null)
            dialog.dismiss();   
    }

    protected void onPreExecute() {
        super.onPreExecute();
        dialog.setTitle(title);
        dialog.setMessage("Wait...");
        dialog.setCancelable(false); 
        dialog.show();
    }

    @Override

Create a UUID.

I know this question is old, but I stumbled upon it looking for a pythonic way to get current domain.

def myview(request):
    domain = request.build_absolute_uri('/')[:-1]
    # that will build the complete domain: http://foobar.com

Use the date function:

select date(timestamp_field) from table

From a character field representation to a date you can use:

select date(substring('2011/05/26 09:00:00' from 1 for 10));

Test code:

create table test_table (timestamp_field timestamp);
insert into test_table (timestamp_field) values(current_timestamp);
select timestamp_field, date(timestamp_field) from test_table;

Test result:

Go to SETTINGS->Location and Security-> Device Administrator and deselect the admin which you want to uninstall.

Now uninstall the application. If it still says you need to deactivate the application before uninstalling, you may need to Force Stop the application before uninstalling.

If a linked server is not allowed by your dba, you can use OPENROWSET. Books Online will provide the syntax you need.

I finally came up with a handy utility function with a unified interface to iterate Objects, Strings, Arrays, TypedArrays, Maps, Sets, (any Iterables).

const iterate = require('@a-z/iterate-it');
const obj = { a: 1, b: 2, c: 3 };

iterate(obj, (value, key) => console.log(key, value)); 
// a 1
// b 2
// c 3

Now that the new anaconda individual edition 2020 distribution is out, the procedure that follows is working:

Update conda in your base env:

conda update conda

Create a new environment for Python 3.8, specifying anaconda for the full distribution specification, not just the minimal environment:

conda create -n py38 python=3.8 anaconda

Activate the new environment:

conda activate py38

python --version
Python 3.8.1

Number of packages installed: 303

Or you can do:

conda create -n py38 anaconda=2020.02 python=3.8

--> UPDATE: Finally, Anaconda3-2020.07 is out with core Python 3.8.3

You can download Anaconda with Python 3.8 from https://www.anaconda.com/products/individual

I was able to read a 4GB log file in about 50 seconds with the following. You may be able to make it faster by loading it as a C# assembly dynamically using PowerShell.

[System.IO.StreamReader]$sr = [System.IO.File]::Open($file, [System.IO.FileMode]::Open)
while (-not $sr.EndOfStream){
    $line = $sr.ReadLine()
}
$sr.Close() 

With the v3 API, you can easily close the InfoWindow with the InfoWindow.close() method. You simply need to keep a reference to the InfoWindow object that you are using. Consider the following example, which opens up an InfoWindow and closes it after 5 seconds:

<!DOCTYPE html>
<html> 
<head> 
  <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> 
  <title>Google Maps API InfoWindow Demo</title> 
  <script src="http://maps.google.com/maps/api/js?sensor=false" 
          type="text/javascript"></script>
</head> 
<body>
  <div id="map" style="width: 400px; height: 500px;"></div>

  <script type="text/javascript">
    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 4,
      center: new google.maps.LatLng(-25.36388, 131.04492),
      mapTypeId: google.maps.MapTypeId.ROADMAP
    });

    var marker = new google.maps.Marker({
      position: map.getCenter(),
      map: map
    });

    var infowindow = new google.maps.InfoWindow({
      content: 'An InfoWindow'
    });

    infowindow.open(map, marker);

    setTimeout(function () { infowindow.close(); }, 5000);
  </script>
</body>
</html>

If you have a separate InfoWindow object for each Marker, you may want to consider adding the InfoWindow object as a property of your Marker objects:

var marker = new google.maps.Marker({
  position: map.getCenter(),
   map: map
});

marker.infowindow = new google.maps.InfoWindow({
  content: 'An InfoWindow'
});

Then you would be able to open and close that InfoWindow as follows:

marker.infowindow.open(map, marker);
marker.infowindow.close();

The same applies if you have an array of markers:

var markers = [];

marker[0] = new google.maps.Marker({
  position: map.getCenter(),
   map: map
});

marker[0].infowindow = new google.maps.InfoWindow({
  content: 'An InfoWindow'
});

// ...

marker[0].infowindow.open(map, marker);
marker[0].infowindow.close();

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-checkout Documentation
• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

For even more robustness:

function getIframeWindow(iframe_object) {
  var doc;

  if (iframe_object.contentWindow) {
    return iframe_object.contentWindow;
  }

  if (iframe_object.window) {
    return iframe_object.window;
  } 

  if (!doc && iframe_object.contentDocument) {
    doc = iframe_object.contentDocument;
  } 

  if (!doc && iframe_object.document) {
    doc = iframe_object.document;
  }

  if (doc && doc.defaultView) {
   return doc.defaultView;
  }

  if (doc && doc.parentWindow) {
    return doc.parentWindow;
  }

  return undefined;
}

and

...
var el = document.getElementById('targetFrame');

var frame_win = getIframeWindow(el);

if (frame_win) {
  frame_win.reset();
  ...
}
...

Actually it depends on your use case.

1) You want to protect your route from unauthorized users

If that is the case you can use the component called <Redirect /> and can implement the following logic:

import React from 'react'
import  { Redirect } from 'react-router-dom'

const ProtectedComponent = () => {
  if (authFails)
    return <Redirect to='/login'  />
  }
  return <div> My Protected Component </div>
}

Keep in mind that if you want <Redirect /> to work the way you expect, you should place it inside of your component's render method so that it should eventually be considered as a DOM element, otherwise it won't work.

2) You want to redirect after a certain action (let's say after creating an item)

In that case you can use history:

myFunction() {
  addSomeStuff(data).then(() => {
      this.props.history.push('/path')
    }).catch((error) => {
      console.log(error)
    })

or

myFunction() {
  addSomeStuff()
  this.props.history.push('/path')
}

In order to have access to history, you can wrap your component with an HOC called withRouter. When you wrap your component with it, it passes match location and history props. For more detail please have a look at the official documentation for withRouter.

If your component is a child of a <Route /> component, i.e. if it is something like <Route path='/path' component={myComponent} />, you don't have to wrap your component with withRouter, because <Route /> passes match, location, and history to its child.

3) Redirect after clicking some element

There are two options here. You can use history.push() by passing it to an onClick event:

<div onClick={this.props.history.push('/path')}> some stuff </div>

or you can use a <Link /> component:

 <Link to='/path' > some stuff </Link>

I think the rule of thumb with this case is to try to use <Link /> first, I suppose especially because of performance.

This is not actually adding the CSS to the cell, but gives the same effect. While providing the same result as others above, this version is a little more intuitive to me, but I'm a novice, so take it for what it's worth:

$(".hoverCell").bind('mouseover', function() {
    var old_color = $(this).css("background-color");
    $(this)[0].style.backgroundColor = '#ffff00';

    $(".hoverCell").bind('mouseout', function () {
        $(this)[0].style.backgroundColor = old_color;
    });
});

This requires setting the Class for each of the cells you want to highlight to "hoverCell".

You can also use nonzero() by using it on a boolean mask of the condition, because False is also a kind of zero.

>>> x = numpy.array([1,0,2,0,3,0,4,5,6,7,8])

>>> x==0
array([False, True, False, True, False, True, False, False, False, False, False], dtype=bool)

>>> numpy.nonzero(x==0)[0]
array([1, 3, 5])

It's doing exactly the same as mtrw's way, but it is more related to the question ;)

We have two commands, first is "condition_command", second is "result_command". If we need run "result_command" when "condition_command" is successful (errorlevel=0):

condition_command && result_command

If we need run "result_command" when "condition_command" is fail:

condition_command || result_command

Therefore for run "some_command" in case when we have "string" in the file "status.txt":

find "string" status.txt 1>nul && some_command

in case when we have not "string" in the file "status.txt":

find "string" status.txt 1>nul || some_command

I can suggest you another approach IMHO more robust. Basically you need to broadcast a logout message to all your Activities needing to stay under a logged-in status. So you can use the sendBroadcast and install a BroadcastReceiver in all your Actvities. Something like this:

/** on your logout method:**/
Intent broadcastIntent = new Intent();
broadcastIntent.setAction("com.package.ACTION_LOGOUT");
sendBroadcast(broadcastIntent);

The receiver (secured Activity):

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    /**snip **/
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction("com.package.ACTION_LOGOUT");
    registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.d("onReceive","Logout in progress");
            //At this point you should start the login activity and finish this one
            finish();
        }
    }, intentFilter);
    //** snip **//
}

Use the os.EOL constant instead.

var os = require("os");

function processInput ( text ) 
{     
  fs.open('H://log.txt', 'a', 666, function( e, id ) {
   fs.write( id, text + os.EOL, null, 'utf8', function(){
    fs.close(id, function(){
     console.log('file is updated');
    });
   });
  });
 }

Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

netstat -p -l | grep $PORT and lsof -i :$PORT solutions are good but I prefer fuser $PORT/tcp extension syntax to POSIX (which work for coreutils) as with pipe:

pid=`fuser $PORT/tcp`

it prints pure pid so you can drop sed magic out.

One thing that makes fuser my lover tools is ability to send signal to that process directly (this syntax is also extension to POSIX):

$ fuser -k $port/tcp       # with SIGKILL
$ fuser -k -15 $port/tcp   # with SIGTERM
$ fuser -k -TERM $port/tcp # with SIGTERM

Also -k is supported by FreeBSD: http://www.freebsd.org/cgi/man.cgi?query=fuser

Here's one for for office workers using a computer shared by others.

I did put my user path in path and created the PYTHONPATH variables in my computer's PATH variable. Its listed under Environment Variables in Computer Properties -> Advanced Settings in Windows 7.

Example:

C:\Users\randuser\AppData\Local\Programs\Python\Python37

This made it so I could use the command prompt.

Hope this helped.

        new System.IO.FileInfo(targetFile).Rename(newFileName);
    }
}

Notice the repetition of Book in Booknumber (int), Booktitle (string), Booklanguage (string), Bookprice (int)- it screams for a class type.

class Book {
  int number;
  String title;
  String language;
  int price;
}

Now you can simply have:

Book[] books = new Books[3];

If you want arrays, you can declare it as object array an insert Integer and String into it:

Object books[3][4]

I had same problem, I solved this problem by following way.

Right click on page, select Property. in build action select Content.

Hope that this solution may help you.

Although ANSI C does not have this mechanism, it is possible to use itoa() as a shortcut:

  char buffer [33];
  itoa (i,buffer,2);
  printf ("binary: %s\n",buffer);

Here's the origin:

itoa in cplusplus reference

It is non-standard C, but K&R mentioned the implementation in the C book, so it should be quite common. It should be in stdlib.h.

Everythings works well. You can't use divtag.onclick, becease "onclick" attribute doesn't exist. You need first create this attribute by using .setAttribute(). Look on this http://reference.sitepoint.com/javascript/Element/setAttribute . You should read documentations first before you start giving "-".

So, there is no difference between MySQL "database" and MySQL "schema": these are two names for the same thing - a namespace for tables and other DB objects.

For people with Oracle background: MySQL "database" a.k.a. MySQL "schema" corresponds to Oracle schema. The difference between MySQL and Oracle CREATE SCHEMA commands is that in Oracle the CREATE SCHEMA command does not actually create a schema but rather populates it with tables and views. And Oracle's CREATE DATABASE command does a very different thing than its MySQL counterpart.

Here's your one-liner, without using any regular expressions, which can get expensive at times:

>>> ''.join(filter(str.isdigit, "1234GAgade5312djdl0"))

returns:

'123453120'

Difference between these to methods are, how you want to pass the parameters.

“A for array and C for comma” is a handy mnemonic.

sed '0,/pattern/s/pattern/replacement/' filename

this worked for me.

example

sed '0,/<Menu>/s/<Menu>/<Menu><Menu>Sub menu<\/Menu>/' try.txt > abc.txt

^{Editor's note: both work with GNU sed only.}

find /path/to/ -type f -print0 | xargs -0 file | grep -i image

This uses the file command to try to recognize the type of file, regardless of filename (or extension).

If /path/to or a filename contains the string image, then the above may return bogus hits. In that case, I'd suggest

cd /path/to
find . -type f -print0 | xargs -0 file --mime-type | grep -i image/

In Laravel 3, call path('storage').

In Laravel 4, use the storage_path() helper function.

I'm going to leave this one here: https://stackoverflow.com/a/14509697/1356953

Please note that this works with java.lang.SuppressWarningsso no need to use a separate annotation.

@SuppressWarnings on a field only suppresses findbugs warnings reported for that field declaration, not every warning associated with that field.

For example, this suppresses the "Field only ever set to null" warning:

@SuppressWarnings("UWF_NULL_FIELD") String s = null; I think the best you can do is isolate the code with the warning into the smallest method you can, then suppress the warning on the whole method.

The shortest way I know

min = tm.minute // 10 * 10

Motivation for another answer

I like very short, clear, guaranteed code. Bonus point if it does not run an external program, since the day you need to process a huge number of entries, it will be noticeably faster.

Principle

Not sure about what guarantees you have and want, so offering anyway.

If you have guarantees you can do it with very short code. The idea is to use bash text substitution feature to cut the last slash and whatever follows.

Answer from simple to more complex cases of the original question.

If path is guaranteed to end without any slash (in and out)

P=/home/smith/Desktop/Test ; echo "${P%/*}"
/home/smith/Desktop

If path is guaranteed to end with exactly one slash (in and out)

P=/home/smith/Desktop/Test/ ; echo "${P%/*/}/"
/home/smith/Desktop/

If input path may end with zero or one slash (not more) and you want output path to end without slash

for P in \
    /home/smith/Desktop/Test \
    /home/smith/Desktop/Test/
do
    P_ENDNOSLASH="${P%/}" ; echo "${P_ENDNOSLASH%/*}"
done

/home/smith/Desktop
/home/smith/Desktop

If input path may have many extraneous slashes and you want output path to end without slash

for P in \
    /home/smith/Desktop/Test \
    /home/smith/Desktop/Test/ \
    /home/smith///Desktop////Test// 
do
    P_NODUPSLASH="${P//\/*(\/)/\/}"
    P_ENDNOSLASH="${P_NODUPSLASH%%/}"
    echo "${P_ENDNOSLASH%/*}";   
done

/home/smith/Desktop
/home/smith/Desktop
/home/smith/Desktop

Im new to RoR this is what I found out. you can directly render a json format

def YOUR_METHOD_HERE
  users = User.all
  render json: {allUsers: users} # ! rendering all users
END

You can use SystemSound, for example, System.Media.SystemSounds.Asterisk.Play();.

As mentioned, you simply want the standard R apply function applied to columns (MARGIN=2):

wifi[,4:9] <- apply(wifi[,4:9], MARGIN=2, FUN=A)

Or, for short:

wifi[,4:9] <- apply(wifi[,4:9], 2, A)

This updates columns 4:9 in-place using the A() function. Now, let's assume that na.rm is an argument to A(), which it probably should be. We can pass na.rm=T to remove NA values from the computation like so:

wifi[,4:9] <- apply(wifi[,4:9], MARGIN=2, FUN=A, na.rm=T)

The same is true for any other arguments you want to pass to your custom function.

Correct, closing the shell will stop MongoDB. Try using the --fork command line arg for the mongod process which makes it run as a daemon instead. I'm no Unix guru, but I'm sure there must be a way to then get it to auto start when the machine boots up.

e.g.

mongod --fork --logpath /var/log/mongodb.log --logappend

Check out the full documentation on Starting and Stopping Mongo.

While the question has been answered in general, I've found myself that there's a case when even existing known_hosts entry doesn't help. This happens when an SSH server sends ECDSA fingerprint and as a result, you'll have an entry like this:

|1|+HASH=|HASH= ecdsa-sha2-nistp256 FINGERPRINT=

The problem is that JSch prefers SHA_RSA and while connecting it will try to compare SHA-RSA fingerprint, which will result with error about "unknown host".

To fix this simply run:

$ ssh-keyscan -H -t rsa example.org >> known_hosts

or complain to Jcraft about prefering SHA_RSA instead of using the local HostKeyAlgorithms setting, although they don't seem to be too eager to fix their bugs.

Very simple to fix, you just need to turn the parameter to writerow into a list.

for item in RESULTS:
     wr.writerow([item,])

The following link will explain how to make that alias permanent so you don't have to keep typing it in.

https://askubuntu.com/questions/17536/how-do-i-create-a-permanent-bash-alias

These are the steps detailed at that link.

1. vim ~/.bashrc or gedit ~/.bashrc or what ever text editor you like
2. put alias cls='printf "\033c"' at the bottom of the file
3. save and exit
4. . ~/.bashrc (and yes there should be a space between . and ~)
5. now check to see if everything worked!

I take no credit for this information just passing it along.

This is just micro-optimisation that you shouldn't worry about.

char[] chars = str.toCharArray();

returns you a copy of str character arrays (in JDK, it returns a copy of characters by calling System.arrayCopy).

Other than that, str.charAt() only checks if the index is indeed in bounds and returns a character within the array index.

The first one doesn't create additional memory in JVM.

I think Fresher gave us nice way, but there is a mistake:

    <script type="text/javascript">
        function setCookie(key, value) {
            var expires = new Date();
            expires.setTime(expires.getTime() + (value * 24 * 60 * 60 * 1000));
            document.cookie = key + '=' + value + ';expires=' + expires.toUTCString();
        }

        function getCookie(key) {
            var keyValue = document.cookie.match('(^|;) ?' + key + '=([^;]*)(;|$)');
            return keyValue ? keyValue[2] : null;
        }
   </script>

You should add "value" near getTime(); otherwise the cookie will expire immediately :)

gstreamer can handle webcam input. If I remeber well, there are python bindings for it!

First of all, let's differentiate between GET and POST

Get: It is the default HTTP request that is made to the server and is used to retrieve the data from the server and query string that comes after ? in a URI is used to retrieve a unique resource.

this is the format

GET /someweb.asp?data=value HTTP/1.0

here data=value is the query string value passed.

POST: It is used to send data to the server safely so anything that is needed, this is the format of a POST request

POST /somweb.aspHTTP/1.0
Host: localhost
Content-Type: application/x-www-form-urlencoded //you can put any format here
Content-Length: 11 //it depends
Name= somename

Why POST over GET?

In GET the value being sent to the servers are usually appended to the base URL in the query string,now there are 2 consequences of this

• The GET requests are saved in browser history with the parameters. So your passwords remain un-encrypted in browser history. This was a real issue for Facebook back in the days.
• Usually servers have a limit on how long a URI can be. If have too many parameters being sent you might receive 414 Error - URI too long

In case of post request your data from the fields are added to the body instead. Length of request params is calculated, and added to the header for content-length and no important data is directly appended to the URL.

You can use the Google Developer Tools' network section to see basic information about how requests are made to the servers.

and you can always add more values in your Request Headers like Cache-Control , Origin , Accept.

'cacerts' is a truststore. A trust store is used to authenticate peers. A keystore is used to authenticate yourself.

& is a character; & is a HTML character entity for that character.

<br> is an element. Elements don't get character entities.

In contrast to many answers here, \n or 
 are not equivalent to <br>. The former denotes a line break in text documents. The latter is intended to denote a line break in HTML documents and is doing that by virtue of its default CSS:

br:before { content: "\A"; white-space: pre-line }

A textual line break can be rendered as an HTML line break or can be treated as whitespace, depending on the CSS white-space property.

To search in all sub-directories, but only in specific file types, use grep with --include.

For example, searching recursively in current directory, for text in *.yml and *.yaml :

grep "text to search" -r . --include=*.{yml,yaml}

The first time around, you allocate memory for Vector, which means the variables x,n.

However x doesn't yet point to anything useful.

So that is why second allocation is needed as well.

Something like this should do the trick:

$(document).ready(function() {
    $('#toptitle').text(function(i, oldText) {
        return oldText === 'Profil' ? 'New word' : oldText;
    });
});

This only replaces the content when it is Profil. See text in the jQuery API.

ME.find({pictures: {$exists: true}}) 

Simple as that, this worked for me.

The following is a group of versatile C functions for timer management based on the gettimeofday() system call. All the timer properties are contained in a single ticktimer struct - the interval you want, the total running time since the timer initialization, a pointer to the desired callback you want to call, the number of times the callback was called. A callback function would look like this:

void your_timer_cb (struct ticktimer *t) {
  /* do your stuff here */
}

To initialize and start a timer, call ticktimer_init(your_timer, interval, TICKTIMER_RUN, your_timer_cb, 0).

In the main loop of your program call ticktimer_tick(your_timer) and it will decide whether the appropriate amount of time has passed to invoke the callback.

To stop a timer, just call ticktimer_ctl(your_timer, TICKTIMER_STOP).

The proper way would be to use $_SERVER["PHP_SELF"] (in conjunction with htmlspecialchars to avoid possible exploits). You can also just skip the action= part empty, which is not W3C valid, but currently works in most (all?) browsers - the default is to submit to self if it's empty.

Here is an example form that takes a name and email, and then displays the values you have entered upon submit:

<?php if (!empty($_POST)): ?>
    Welcome, <?php echo htmlspecialchars($_POST["name"]); ?>!<br>
    Your email is <?php echo htmlspecialchars($_POST["email"]); ?>.<br>
<?php else: ?>
    <form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
        Name: <input type="text" name="name"><br>
        Email: <input type="text" name="email"><br>
        <input type="submit">
    </form>
<?php endif; ?>

If the user is sophisticated or determined enough to:

1. Open the Excel VBA editor
2. Use the object browser to see the list of all sheets, including VERYHIDDEN ones
3. Change the property of the sheet to VISIBLE or just HIDDEN

then they are probably sophisticated or determined enough to:

1. Search the internet for "remove Excel 2007 project password"
2. Apply the instructions they find.

So what's on this hidden sheet? Proprietary information like price formulas, or client names, or employee salaries? Putting that info in even an hidden tab probably isn't the greatest idea to begin with.

The following works for springboot 1.3 and above:

As init.d service

The executable jar has the usual start, stop, restart, and status commands. It will also set up a PID file in the usual /var/run directory and logging in the usual /var/log directory by default.

You just need to symlink your jar into /etc/init.d like so

sudo link -s /var/myapp/myapp.jar /etc/init.d/myapp

OR

sudo ln -s ~/myproject/build/libs/myapp-1.0.jar /etc/init.d/myapp_servicename

After that you can do the usual

/etc/init.d/myapp start

Then setup a link in whichever runlevel you want the app to start/stop in on boot if so desired.

As a systemd service

To run a Spring Boot application installed in var/myapp you can add the following script in /etc/systemd/system/myapp.service:

[Unit]
Description=myapp
After=syslog.target

[Service]
ExecStart=/var/myapp/myapp.jar

[Install]
WantedBy=multi-user.target

NB: in case you are using this method, do not forget to make the jar file itself executable (with chmod +x) otherwise it will fail with error "Permission denied".

Converting String array into stream and mapping to int is the best option available in java 8.

    String[] stringArray = new String[] { "0", "1", "2" };
    int[] intArray = Stream.of(stringArray).mapToInt(Integer::parseInt).toArray();
    System.out.println(Arrays.toString(intArray));

After installing run below command

sudo chmod 755 -R laravel
chmod -R o+w laravel/storage

here "laravel" is the name of directory where laravel installed

On the Unity Editor open your project and:

1. Enable External option in Unity ? Preferences ? Packages ? Repository (only if Unity ver < 4.5)
2. Switch to Visible Meta Files in Edit ? Project Settings ? Editor ? Version Control Mode
3. Switch to Force Text in Edit ? Project Settings ? Editor ? Asset Serialization Mode
4. Save Scene and Project from File menu.
5. Quit Unity and then you can delete the Library and Temp directory in the project directory. You can delete everything but keep the Assets and ProjectSettings directory.

If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:

cd to/your/unity/project/folder

git init

git add *

git commit -m "First commit"

git remote add origin [email protected]:username/project.git

git push -u origin master

You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).

Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.

And here's my own .gitignore recipe for my Unity projects:

I don't think there's any reason to add this function to JQuery's namespace. Why not just define the method by itself:

function showMessage(msg) {
   alert(msg);
};

<input type="button" value="ahaha" onclick="showMessage('msg');" />

UPDATE: With a small change to how your method is defined I can get it to work:

<html>
<head>
 <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
 <script language="javascript">
    // define the function within the global scope
    $.fn.MessageBox = function(msg) {
        alert(msg);
    };

    // or, if you want to encapsulate variables within the plugin
    (function($) {
        $.fn.MessageBoxScoped = function(msg) {
            alert(msg);
        };
    })(jQuery); //<-- make sure you pass jQuery into the $ parameter
 </script>
</head>
<body>
 <div class="Title">Welcome!</div>
 <input type="button" value="ahaha" id="test" onClick="$(this).MessageBox('msg');" />
</body>
</html>

df.loc[:,'col':] = df.loc[:,'col':].apply(pd.to_numeric, errors = 'coerce')

you need to create a type and make the attribute of that type:

<xs:simpleType name="curr">
  <xs:restriction base="xs:string">
    <xs:enumeration value="pounds" />
    <xs:enumeration value="euros" />
    <xs:enumeration value="dollars" />
  </xs:restriction>
</xs:simpleType>

then:

<xs:complexType>
    <xs:attribute name="currency" type="curr"/>
</xs:complexType>

I had a different issue with the same exception.

In short:

Make sure that the Bitmap's object Stream is not being disposed before calling .Save .

Full story:

There was a method that returned a Bitmap object, built from a MemoryStream in the following way:

private Bitmap getImage(byte[] imageBinaryData){
    .
    .
    .
    Bitmap image;
    using (var stream = new MemoryStream(imageBinaryData))
    {
        image = new Bitmap(stream);
    }
    return image;
}

then someone used the returned image to save it as a file

image.Save(path);

The problem was that the original stream was already disposed when trying to save the image, throwing the GDI+ exeption.

A fix to this problem was to return the Bitmap without disposing the stream itself but the returned Bitmap object.

private Bitmap getImage(byte[] imageBinaryData){
   .
   .
   .
   Bitmap image;
   var stream = new MemoryStream(imageBinaryData))
   image = new Bitmap(stream);

   return image;
}

then:

using (var image = getImage(binData))
{
   image.Save(path);
}

All the hidden fields in your fieldset are using the same id, so jquery is only returning the first one. One way to fix this is to create a counter variable and concatenate it to each hidden field id.

I thought of

 SELECT LENGTH('123-345-566') - LENGTH(REPLACE('123-345-566', '-', '')) FROM DUAL;

you can add the class .datepicker in a javascript function, to be able to dynamically change the input type

 $("#ddlDefault").addClass("datepicker");
 $(".datepicker").datetimepicker({ timepicker: false, format: 'd/m/Y', });

jQuery is still popular, but if you want to have no dependencies, see below. Short & clear function to find out if radio button is checked on ES-2015:

function getValueFromRadioButton( name ){_x000D_
  return [...document.getElementsByName(name)]_x000D_
         .reduce( (rez, btn) => (btn.checked ? btn.value : rez), null)_x000D_
}_x000D_
_x000D_
console.log( getValueFromRadioButton('payment') );

<div>  _x000D_
  <input type="radio" name="payment" value="offline">_x000D_
  <input type="radio" name="payment" value="online">_x000D_
  <input type="radio" name="payment" value="part" checked>_x000D_
  <input type="radio" name="payment" value="free">_x000D_
</div>

You need to change your Ajax call to

$.ajax({
    type: "POST",
    url: "/people",
    data: '[{ "name": "John", "location": "Boston" }, { "name": "Dave", "location": "Lancaster" }]',
    contentType: "json",
    processData: false,
    success:function(data) {
        $('#save_message').html(data.message);
    } 
});

change the dataType to contentType and add the processData option.

To retrieve the JSON payload from your controller, use:

dd(json_decode($request->getContent(), true));

instead of

dd($request->all());

Use .push:

items.push({'id':5});

If you are working with php in windows, you can just access to the file "php.ini" located in your php instalation folder and uncomment the ";extension=xmlrpc" line deleting the ";" ("extension=xmlrpc")

Maybe you are out of inodes. Try df -i

                     2591792  136322 2455470    6% /home
/dev/sdb1            1887488 1887488       0  100% /data

Disk used 6% but inode table full.

IF exists

IF exists (select * from table_1 where col1 = 'value')
BEGIN
    -- one or more
    insert into table_1 (col1) values ('valueB')
END
ELSE
    -- zero
    insert into table_1 (col1) values ('value') 

Do you mean immediate subdirectories, or every directory right down the tree?

Either way, you could use os.walk to do this:

os.walk(directory)

will yield a tuple for each subdirectory. Ths first entry in the 3-tuple is a directory name, so

[x[0] for x in os.walk(directory)]

should give you all of the subdirectories, recursively.

Note that the second entry in the tuple is the list of child directories of the entry in the first position, so you could use this instead, but it's not likely to save you much.

However, you could use it just to give you the immediate child directories:

next(os.walk('.'))[1]

Or see the other solutions already posted, using os.listdir and os.path.isdir, including those at "How to get all of the immediate subdirectories in Python".

You can go without the loop:

find /path/to/dir -type f -exec /your/first/command \{\} \; -exec /your/second/command \{\} \;

Non-jquery:

// Very old browsers
// var linkList = document.getElementById('link_other').getElementsByTagName('a');

// New browsers (IE8+)
var linkList = document.querySelectorAll('#link_other a');

for(var i in linkList){
 linkList[i].setAttribute('target', '_blank');
}

Use <div class="row"> and <div class="form-group col-xs-6">

Here a fiddle :https://jsfiddle.net/core972/SMkZV/2/

My idea of that program is that:

package text;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class CoutingWords {

    public static void main(String[] args) throws IOException {
        String str;
        int cWords = 1;
        char ch;

        BufferedReader buffor = new BufferedReader(new InputStreamReader(System.in));

        System.out.println("Enter text: ");
        str = buffor.readLine();

        for(int i =0; i<str.length(); i++){
            ch = str.charAt(i);
            if(Character.isWhitespace(ch)){ cWords++; }
        }
        System.out.println("There are " + (int)cWords +" words.");
    }
}

If anyone else comes across this and the accepted answer doesn't work (it didn't for me), check to see if you need to specify a port other than 80. In my case, I was running a rails server at localhost:3000 and was just using curl http://localhost, which was hitting port 80.

Changing the command to curl http://localhost:3000 is what worked in my case.

The following will just print out the content of the file:

cat $Path/FileName.txt

while read line;
do
echo $line     
done

strings = ("string1", "string2", "string3")
for line in file:
    if any(s in line for s in strings):
        print "yay!"

The other answers lack a concrete example, so here it goes:

Given the following People table:

 FirstName |  LastName   |  YearOfBirth
----------------------------------------
  Thomas   | Alva Edison |   1847
  Benjamin | Franklin    |   1706
  Thomas   | More        |   1478
  Thomas   | Jefferson   |   1826

If you execute the query below:

SELECT * FROM People ORDER BY FirstName DESC, YearOfBirth ASC

The result set will look like this:

 FirstName |  LastName   |  YearOfBirth
----------------------------------------
  Thomas   | More        |   1478
  Thomas   | Jefferson   |   1826
  Thomas   | Alva Edison |   1847
  Benjamin | Franklin    |   1706

^{The original query used user variables and ORDER BY on derived tables; the behavior of both quirks is not guaranteed. Revised answer as follows.}

In MySQL 5.x you can use poor man's rank over partition to achieve desired result. Just outer join the table with itself and for each row, count the number of rows lesser than it. In the above case, lesser row is the one with higher rate:

SELECT t.id, t.rate, t.year, COUNT(l.rate) AS rank
FROM t
LEFT JOIN t AS l ON t.id = l.id AND t.rate < l.rate
GROUP BY t.id, t.rate, t.year
HAVING COUNT(l.rate) < 5
ORDER BY t.id, t.rate DESC, t.year

Demo and Result:

| id  | rate | year | rank |
|-----|------|------|------|
| p01 |  8.0 | 2006 | 0    |
| p01 |  7.4 | 2003 | 1    |
| p01 |  6.8 | 2008 | 2    |
| p01 |  5.9 | 2001 | 3    |
| p01 |  5.3 | 2007 | 4    |
| p02 | 12.5 | 2001 | 0    |
| p02 | 12.4 | 2004 | 1    |
| p02 | 12.2 | 2002 | 2    |
| p02 | 10.3 | 2003 | 3    |
| p02 |  8.7 | 2000 | 4    |

Note that if the rates had ties, for example:

100, 90, 90, 80, 80, 80, 70, 60, 50, 40, ...

The above query will return 6 rows:

100, 90, 90, 80, 80, 80

Change to HAVING COUNT(DISTINCT l.rate) < 5 to get 8 rows:

100, 90, 90, 80, 80, 80, 70, 60

Or change to ON t.id = l.id AND (t.rate < l.rate OR (t.rate = l.rate AND t.pri_key > l.pri_key)) to get 5 rows:

 100, 90, 90, 80, 80

In MySQL 8 or later just use the RANK, DENSE_RANK or ROW_NUMBER functions:

SELECT *
FROM (
    SELECT *, RANK() OVER (PARTITION BY id ORDER BY rate DESC) AS rnk
    FROM t
) AS x
WHERE rnk <= 5

OP's efficient code has a bug:

when a == b, and a (or b) < c, the code will pick c instead of a or b.

If you want it in pure CSS:

pointer-events:none;

Some people find the following alternative syntax easier to see what is going on:

select t1.value,t2.value
from MyTable t1
    inner join MyTable t2 on
        t1.id = t2.id
where t1.id = @id

I don't know why you think there's no constructor. See the API.

1.84E-07 is the exact value, represented using scientific notation, also known as exponential notation.

1.845E-07 is the same as 0.0000001845. Excel will display a number very close to 0 as 0, unless you modify the formatting of the cell to display more decimals.

C# however will get the actual value from the cell. The ToString method use the e-notation when converting small numbers to a string.

You can specify a format string if you don't want to use the e-notation.

You can use:

CREATE LOGIN <login name> WITH PASSWORD = '<password>' ; GO 

To create the login (See here for more details).

Then you may need to use:

CREATE USER user_name 

To create the user associated with the login for the specific database you want to grant them access too.

(See here for details)

You can also use:

GRANT permission  [ ,...n ] ON SCHEMA :: schema_name

To set up the permissions for the schema's that you assigned the users to.

(See here for details)

Two other commands you might find useful are ALTER USER and ALTER LOGIN.

So... facebook distinguishes pretty harshly between http and https in your app. This is just another small thing to check if you run into trouble.

Here is my one liner for this.

 file_count=$( shopt -s nullglob ; set -- $directory_to_search_inside/* ; echo $#)

You can use google gson library to convert json object.

Other librarys like Jackson are also available.

This won't convert it to a map. But you can do all things which you want.
