As of Xcode 8.2.1, iOS 10, and swift 3,

You can determine the end of tableView.reloadData() easily by using a CATransaction block:

CATransaction.begin()
CATransaction.setCompletionBlock({
    print("reload completed")
    //Your completion code here
})
print("reloading")
tableView.reloadData()
CATransaction.commit()

The above also works for determining the end of UICollectionView's reloadData() and UIPickerView's reloadAllComponents().

Constraints can be used to enforce specific properties of data. A simple example is to limit an int column to values [0-100000]. This introduction looks good.

If it's working in the debug, then wait must be the proper solution.
I will suggest to use the explicit wait, as given below:

WebDriverWait wait = new WebDriverWait(new ChromeDriver(), 5);
wait.until(ExpectedConditions.presenceOfElementLocated(By.cssSelector("#Passwd")));

To toggle the input's disabled attribute was surprisingly complex. The issue for me was twofold:

(1) Remember: the input's "disabled" attribute is NOT a Boolean attribute.
The mere presence of the attribute means that the input is disabled.

However, the Vue.js creators have prepared this... https://vuejs.org/v2/guide/syntax.html#Attributes

(Thanks to @connexo for this... How to add disabled attribute in input text in vuejs?)

(2) In addition, there was a DOM timing re-rendering issue that I was having. The DOM was not updating when I tried to toggle back.

Upon certain situations, "the component will not re-render immediately. It will update in the next 'tick.'"

From Vue.js docs: https://vuejs.org/v2/guide/reactivity.html

The solution was to use:

this.$nextTick(()=>{
    this.disableInputBool = true
})

Fuller example workflow:

<div @click="allowInputOverwrite">
    <input
        type="text"
        :disabled="disableInputBool">
</div>

<button @click="disallowInputOverwrite">
    press me (do stuff in method, then disable input bool again)
</button>

<script>

export default {
  data() {
    return {
      disableInputBool: true
    }
  },
  methods: {
    allowInputOverwrite(){
      this.disableInputBool = false
    },
    disallowInputOverwrite(){
      // accomplish other stuff here.
      this.$nextTick(()=>{
        this.disableInputBool = true
      })
    }
  }

}
</script>

Depends what you want to do.

If what you want is to retrieve the bytes that are remaining (between position and limit), then what you have will work. You could also just do:

ByteBuffer bb =..

byte[] b = new byte[bb.remaining()];
bb.get(b);

which is equivalent as per the ByteBuffer javadocs.

I don't really understand the full scope of your question, but if all you need is a hash of the string, then it's very easy to get that.

Just use the GetHashCode method.

Like this:

string hash = username.GetHashCode();

It could be that there was a previous Ruby env installed on your system prior to your installation of 2.0? This might have had an existing GEM_PATH that lead to the /1.8 directory which the installation of version 2.0 simply kept.

The problem you where likely having, then, was that Passenger/Apache was looking in the /2.0 directory when in fact the gems were in the /1.8 directory. Your explicitly telling apache to use the /1.8 directory thus makes sense to fix the problem.

SetEnv GEM_HOME /usr/lib/ruby/gems/1.8

You might also try using the Ruby Version Manager to handle multiple Ruby envs.

Some things I found in Google:

• New to Ruby and am having trouble with LOAD_PATH
• http://weblog.rubyonrails.org/2009/9/1/gem-packaging-best-practices/
• http://guides.rubygems.org/faqs/

After instaling the package you need to add the newtonsoft.json.dll into assemble path by runing the flowing command.

Before we can use our assembly, we have to add it to the global assembly cache (GAC). Open the Visual Studio 2008 Command Prompt again (for Vista/Windows7/etc. open it as Administrator). And execute the following command. gacutil /i d:\myMethodsForSSIS\myMethodsForSSIS\bin\Release\myMethodsForSSIS.dll

flow this link for more informATION http://microsoft-ssis.blogspot.com/2011/05/referencing-custom-assembly-inside.html

There are other differences. For instance, {'time': datetime.now()} cannot be serialized to JSON, but can be converted to string. You should use one of these tools depending on the purpose (i.e. will the result later be decoded).

As for VS2017 I didn't find it in "extensions", there's a Nuget package called "microsoft-web-helpers" that seems to be equivalent to System.Web.Helpers.

Here's the whole code snippet needed:

$queried_object = get_queried_object();
$term_id = $queried_object->term_id;

You can write 2 simple functions that actually turns out to be about 5-8 times faster than using scipy.special.comb. In fact, you don't need to import any extra packages, and the function is quite easily readable. The trick is to use memoization to store previously computed values, and using the definition of nCr

# create a memoization dictionary
memo = {}
def factorial(n):
    """
    Calculate the factorial of an input using memoization
    :param n: int
    :rtype value: int
    """
    if n in [1,0]:
        return 1
    if n in memo:
        return memo[n]
    value = n*factorial(n-1)
    memo[n] = value
    return value

def ncr(n, k):
    """
    Choose k elements from a set of n elements - n must be larger than or equal to k
    :param n: int
    :param k: int
    :rtype: int
    """
    return factorial(n)/(factorial(k)*factorial(n-k))

If we compare times

from scipy.special import comb
%timeit comb(100,48)
>>> 100000 loops, best of 3: 6.78 µs per loop

%timeit ncr(100,48)
>>> 1000000 loops, best of 3: 1.39 µs per loop

There should be a line in your postgresql.conf file that says:

port = 1486

Change that.

The location of the file can vary depending on your install options. On Debian-based distros it is /etc/postgresql/8.3/main/

On Windows it is C:\Program Files\PostgreSQL\9.3\data

Don't forget to sudo service postgresql restart for changes to take effect.

Onliner solution for Scala >= 2.12

val source_html = Source.fromResource("file.html").mkString

I've come up with a solution which is similar with RacZo's in the fact that I've also created a subclass of TextView which handles making the text upper-case.

The difference is that instead of overriding one of the setText() methods, I've used a similar approach to what the TextView actually does on API 14+ (which is in my point of view a cleaner solution).

If you look into the source, you'll see the implementation of setAllCaps():

public void setAllCaps(boolean allCaps) {
    if (allCaps) {
        setTransformationMethod(new AllCapsTransformationMethod(getContext()));
    } else {
        setTransformationMethod(null);
    }
}

The AllCapsTransformationMethod class is not (currently) public, but still, the source is also available. I've simplified that class a bit (removed the setLengthChangesAllowed() method), so the complete solution is this:

public class UpperCaseTextView extends TextView {

    public UpperCaseTextView(Context context) {
        super(context);
        setTransformationMethod(upperCaseTransformation);
    }

    public UpperCaseTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        setTransformationMethod(upperCaseTransformation);
    }

    public UpperCaseTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        setTransformationMethod(upperCaseTransformation);
    }

    private final TransformationMethod upperCaseTransformation =
            new TransformationMethod() {

        private final Locale locale = getResources().getConfiguration().locale;

        @Override
        public CharSequence getTransformation(CharSequence source, View view) {
            return source != null ? source.toString().toUpperCase(locale) : null;
        }

        @Override
        public void onFocusChanged(View view, CharSequence sourceText,
                boolean focused, int direction, Rect previouslyFocusedRect) {}
    };
}

Even though this post is caput, I think it's an excellent demonstration of some walls that one can run into with jQuery, i.e. thinking click() actually clicks on an element, rather than just sending a click event bubbling up through the DOM. Let's say you actually need to simulate a click event (i.e. for testing purposes, etc.) If that's the case, provided that you're using a modern browser you can just use HTMLElement.prototype.click (see here for method details as well as a link to the W3 spec). This should work on almost all browsers, especially if you're dealing with links, and you can fall back to window.open pretty easily if you need to:

var clickLink = function(linkEl) {
  if (HTMLElement.prototype.click) {
    // You'll want to create a new element so you don't alter the page element's
    // attributes, unless of course the target attr is already _blank
    // or you don't need to alter anything
    var linkElCopy = $.extend(true, Object.create(linkEl), linkEl);
    $(linkElCopy).attr('target', '_blank');
    linkElCopy.click();
  } else {
    // As Daniel Doezema had said
    window.open($(linkEl).attr('href'));
  }
};

You can use FFserver to stream a video using RTSP.

Just change console syntax to something like this:

ffmpeg -i space.mp4 -vcodec libx264 -tune zerolatency -crf 18 http://localhost:1234/feed1.ffm

Create a ffserver.config file (sample) where you declare HTTPPort, RTSPPort and SDP stream. Your config file could look like this (some important stuff might be missing):

HTTPPort 1234
RTSPPort 1235

<Feed feed1.ffm>
        File /tmp/feed1.ffm
        FileMaxSize 2M
        ACL allow 127.0.0.1
</Feed>

<Stream test1.sdp>
    Feed feed1.ffm
    Format rtp
    Noaudio
    VideoCodec libx264
    AVOptionVideo flags +global_header
    AVOptionVideo me_range 16
    AVOptionVideo qdiff 4
    AVOptionVideo qmin 10
    AVOptionVideo qmax 51
    ACL allow 192.168.0.0 192.168.255.255
</Stream>

With such setup you can watch the stream with i.e. VLC by typing:

rtsp://192.168.0.xxx:1235/test1.sdp

Here is the FFserver documentation.

You cannot manually expire a token after it has been created. Thus, you cannot log out with JWT on the server-side as you do with sessions.

JWT is stateless, meaning that you should store everything you need in the payload and skip performing a DB query on every request. But if you plan to have a strict log out functionality, that cannot wait for the token auto-expiration, even though you have cleaned the token from the client-side, then you might need to neglect the stateless logic and do some queries. so what's a solution?

• Set a reasonable expiration time on tokens

• Delete the stored token from client-side upon log out

• Query provided token against The Blacklist on every authorized request

Blacklist

“Blacklist” of all the tokens that are valid no more and have not expired yet. You can use a DB that has a TTL option on documents which would be set to the amount of time left until the token is expired.

Redis

Redis is a good option for blacklist, which will allow fast in-memory access to the list. Then, in the middleware of some kind that runs on every authorized request, you should check if the provided token is in The Blacklist. If it is you should throw an unauthorized error. And if it is not, let it go and the JWT verification will handle it and identify if it is expired or still active.

For more information, see How to log out when using JWT. by Arpy Vanyan

Assuming that you have access to Prototype, this could work. I wrote this code for myself just a few minutes ago; I only needed a single key at a time, so this isn't time efficient for big lists of key:value pairs or for spitting out multiple key names.

function key(int) {
    var j = -1;
    for(var i in this) {
        j++;
        if(j==int) {
            return i;
        } else {
            continue;
        }
    }
}
Object.prototype.key = key;

This is numbered to work the same way that arrays do, to save headaches. In the case of your code:

buttons.key(0) // Should result in "button1"

Every iteration you are resetting the sequence of pseudorandom numbers because you are calling srand with the same seed (since the call to time is so frequent). Either use a different seed, or call srand once before you enter the loop.

All you need to do is to replace 'import android.support.annotation.Nullable' in class imports to 'import androidx.annotation.Nullable;'

Thats a common practice..whenever any import giving issue...remove that import and simply press Alt+Enter on the related class..that will give you option to 'import class'..hint Enter and things will get resolved...

ECMAScript 2018 introduces named capturing groups into JavaScript regexes.

Example:

  const auth = 'Bearer AUTHORIZATION_TOKEN'
  const { groups: { token } } = /Bearer (?<token>[^ $]*)/.exec(auth)
  console.log(token) // "Prints AUTHORIZATION_TOKEN"

If you need to support older browsers, you can do everything with normal (numbered) capturing groups that you can do with named capturing groups, you just need to keep track of the numbers - which may be cumbersome if the order of capturing group in your regex changes.

There are only two "structural" advantages of named capturing groups I can think of:

1. In some regex flavors (.NET and JGSoft, as far as I know), you can use the same name for different groups in your regex (see here for an example where this matters). But most regex flavors do not support this functionality anyway.

2. If you need to refer to numbered capturing groups in a situation where they are surrounded by digits, you can get a problem. Let's say you want to add a zero to a digit and therefore want to replace (\d) with $10. In JavaScript, this will work (as long as you have fewer than 10 capturing group in your regex), but Perl will think you're looking for backreference number 10 instead of number 1, followed by a 0. In Perl, you can use ${1}0 in this case.

Other than that, named capturing groups are just "syntactic sugar". It helps to use capturing groups only when you really need them and to use non-capturing groups (?:...) in all other circumstances.

The bigger problem (in my opinion) with JavaScript is that it does not support verbose regexes which would make the creation of readable, complex regular expressions a lot easier.

Steve Levithan's XRegExp library solves these problems.

The CSS solution for Angular Bootstrap is

::ng-deep .tooltip-inner {
  white-space: pre-wrap;
}

No need to use a parent element or class selector if you don't need to restrict it's use. Copy/Pasta, and this rule will apply to all sub-components

There is no lawbreaking or outlaw standard other than common sense. If we abstract this like two people talking, the standard is the best way they can accurately understand each other in minimum words in minimum time. In our case, 'minimum words' is optimizing bandwidth for transport efficiency and 'accurately understand' is the structure for parser efficiency; which ultimately ends up with the less the data, and the common the structure; so that it can go through a pin hole and can be parsed through a common scope (at least initially).

Almost in every cases suggested, I see separate responses for 'Success' and 'Error' scenario, which is kind of ambiguity to me. If responses are different in these two cases, then why do we really need to put a 'Success' flag there? Is it not obvious that the absence of 'Error' is a 'Success'? Is it possible to have a response where 'Success' is TRUE with an 'Error' set? Or the way, 'Success' is FALSE with no 'Error' set? Just one flag is not enough? I would prefer to have the 'Error' flag only, because I believe there will be less 'Error' than 'Success'.

Also, should we really make the 'Error' a flag? What about if I want to respond with multiple validation errors? So, I find it more efficient to have an 'Error' node with each error as child to that node; where an empty (counts to zero) 'Error' node would denote a 'Success'.

No CSS required, visible class should like this: visible-md-block not just visible-md and the code should be like this:

<div class="containerdiv hidden-sm hidden-xs visible-md-block visible-lg-block">
    <div class="row">
        <div class="col-xs-4 col-sm-4 col-md-4 col-lg-4 logo">

        </div>
    </div>
</div>

<div class="mobile hidden-md hidden-lg ">
    test
</div>

Extra css is not required at all.

How about simply:

select distinct c1, c2 from t

or

select c1, c2, count(*)
from t
group by c1, c2

Put the select statement in a dynamic PL/SQL block.

CREATE OR REPLACE FUNCTION get_num_of_employees (p_loc VARCHAR2, p_job VARCHAR2) 
RETURN NUMBER
IS
  v_query_str VARCHAR2(1000);
  v_num_of_employees NUMBER;
BEGIN
  v_query_str := 'begin SELECT COUNT(*) INTO :into_bind FROM emp_' 
                 || p_loc
                 || ' WHERE job = :bind_job; end;';
  EXECUTE IMMEDIATE v_query_str
    USING out v_num_of_employees, p_job;
  RETURN v_num_of_employees;
END;
/

With dynamic allocation, using malloc:

int** x;

x = malloc(dimension1_max * sizeof(*x));
for (int i = 0; i < dimension1_max; i++) {
  x[i] = malloc(dimension2_max * sizeof(x[0]));
}

//Writing values
x[0..(dimension1_max-1)][0..(dimension2_max-1)] = Value; 
[...]

for (int i = 0; i < dimension1_max; i++) {
  free(x[i]);
}
free(x);

This allocates an 2D array of size dimension1_max * dimension2_max. So, for example, if you want a 640*480 array (f.e. pixels of an image), use dimension1_max = 640, dimension2_max = 480. You can then access the array using x[d1][d2] where d1 = 0..639, d2 = 0..479.

But a search on SO or Google also reveals other possibilities, for example in this SO question

Note that your array won't allocate a contiguous region of memory (640*480 bytes) in that case which could give problems with functions that assume this. So to get the array satisfy the condition, replace the malloc block above with this:

int** x;
int* temp;

x = malloc(dimension1_max * sizeof(*x));
temp = malloc(dimension1_max * dimension2_max * sizeof(x[0]));
for (int i = 0; i < dimension1_max; i++) {
  x[i] = temp + (i * dimension2_max);
}

[...]

free(temp);
free(x);

I still had the issue above after installing postgresql using homebrew - I resolved it by putting /usr/local/bin in my path before /usr/bin

You can get the path via fp.name. Example:

>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'

You might need os.path.basename if you want only the file name:

>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

There are many ways to download files. Following I will post most common ways; it is up to you to decide which method is better for your app.

1. Use AsyncTask and show the download progress in a dialog

This method will allow you to execute some background processes and update the UI at the same time (in this case, we'll update a progress bar).

Imports:

import android.os.PowerManager;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.FileOutputStream;
import java.net.HttpURLConnection;

This is an example code:

// declare the dialog as a member field of your activity
ProgressDialog mProgressDialog;

// instantiate it within the onCreate method
mProgressDialog = new ProgressDialog(YourActivity.this);
mProgressDialog.setMessage("A message");
mProgressDialog.setIndeterminate(true);
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setCancelable(true);

// execute this when the downloader must be fired
final DownloadTask downloadTask = new DownloadTask(YourActivity.this);
downloadTask.execute("the url to the file you want to download");

mProgressDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {

    @Override
    public void onCancel(DialogInterface dialog) {
        downloadTask.cancel(true); //cancel the task
    }
});

The AsyncTask will look like this:

// usually, subclasses of AsyncTask are declared inside the activity class.
// that way, you can easily modify the UI thread from here
private class DownloadTask extends AsyncTask<String, Integer, String> {

    private Context context;
    private PowerManager.WakeLock mWakeLock;

    public DownloadTask(Context context) {
        this.context = context;
    }

    @Override
    protected String doInBackground(String... sUrl) {
        InputStream input = null;
        OutputStream output = null;
        HttpURLConnection connection = null;
        try {
            URL url = new URL(sUrl[0]);
            connection = (HttpURLConnection) url.openConnection();
            connection.connect();

            // expect HTTP 200 OK, so we don't mistakenly save error report
            // instead of the file
            if (connection.getResponseCode() != HttpURLConnection.HTTP_OK) {
                return "Server returned HTTP " + connection.getResponseCode()
                        + " " + connection.getResponseMessage();
            }

            // this will be useful to display download percentage
            // might be -1: server did not report the length
            int fileLength = connection.getContentLength();

            // download the file
            input = connection.getInputStream();
            output = new FileOutputStream("/sdcard/file_name.extension");

            byte data[] = new byte[4096];
            long total = 0;
            int count;
            while ((count = input.read(data)) != -1) {
                // allow canceling with back button
                if (isCancelled()) {
                    input.close();
                    return null;
                }
                total += count;
                // publishing the progress....
                if (fileLength > 0) // only if total length is known
                    publishProgress((int) (total * 100 / fileLength));
                output.write(data, 0, count);
            }
        } catch (Exception e) {
            return e.toString();
        } finally {
            try {
                if (output != null)
                    output.close();
                if (input != null)
                    input.close();
            } catch (IOException ignored) {
            }

            if (connection != null)
                connection.disconnect();
        }
        return null;
    }

The method above (doInBackground) runs always on a background thread. You shouldn't do any UI tasks there. On the other hand, the onProgressUpdate and onPreExecute run on the UI thread, so there you can change the progress bar:

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        // take CPU lock to prevent CPU from going off if the user 
        // presses the power button during download
        PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
        mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
             getClass().getName());
        mWakeLock.acquire();
        mProgressDialog.show();
    }

    @Override
    protected void onProgressUpdate(Integer... progress) {
        super.onProgressUpdate(progress);
        // if we get here, length is known, now set indeterminate to false
        mProgressDialog.setIndeterminate(false);
        mProgressDialog.setMax(100);
        mProgressDialog.setProgress(progress[0]);
    }

    @Override
    protected void onPostExecute(String result) {
        mWakeLock.release();
        mProgressDialog.dismiss();
        if (result != null)
            Toast.makeText(context,"Download error: "+result, Toast.LENGTH_LONG).show();
        else
            Toast.makeText(context,"File downloaded", Toast.LENGTH_SHORT).show();
    }

For this to run, you need the WAKE_LOCK permission.

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

2. Download from Service

The big question here is: how do I update my activity from a service?. In the next example we are going to use two classes you may not be aware of: ResultReceiver and IntentService. ResultReceiver is the one that will allow us to update our thread from a service; IntentService is a subclass of Service which spawns a thread to do background work from there (you should know that a Service runs actually in the same thread of your app; when you extends Service, you must manually spawn new threads to run CPU blocking operations).

Download service can look like this:

public class DownloadService extends IntentService {
    public static final int UPDATE_PROGRESS = 8344;

    public DownloadService() {
        super("DownloadService");
    }
    @Override
    protected void onHandleIntent(Intent intent) {

        String urlToDownload = intent.getStringExtra("url");
        ResultReceiver receiver = (ResultReceiver) intent.getParcelableExtra("receiver");
        try {

            //create url and connect
            URL url = new URL(urlToDownload);
            URLConnection connection = url.openConnection();
            connection.connect();

            // this will be useful so that you can show a typical 0-100% progress bar
            int fileLength = connection.getContentLength();

            // download the file
            InputStream input = new BufferedInputStream(connection.getInputStream());

            String path = "/sdcard/BarcodeScanner-debug.apk" ;
            OutputStream output = new FileOutputStream(path);

            byte data[] = new byte[1024];
            long total = 0;
            int count;
            while ((count = input.read(data)) != -1) {
                total += count;

                // publishing the progress....
                Bundle resultData = new Bundle();
                resultData.putInt("progress" ,(int) (total * 100 / fileLength));
                receiver.send(UPDATE_PROGRESS, resultData);
                output.write(data, 0, count);
            }

            // close streams 
            output.flush();
            output.close();
            input.close();

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

        Bundle resultData = new Bundle();
        resultData.putInt("progress" ,100);

        receiver.send(UPDATE_PROGRESS, resultData);
    }
}

Add the service to your manifest:

<service android:name=".DownloadService"/>

And the activity will look like this:

// initialize the progress dialog like in the first example

// this is how you fire the downloader
mProgressDialog.show();
Intent intent = new Intent(this, DownloadService.class);
intent.putExtra("url", "url of the file to download");
intent.putExtra("receiver", new DownloadReceiver(new Handler()));
startService(intent);

Here is were ResultReceiver comes to play:

private class DownloadReceiver extends ResultReceiver{

    public DownloadReceiver(Handler handler) {
        super(handler);
    }

    @Override
    protected void onReceiveResult(int resultCode, Bundle resultData) {

        super.onReceiveResult(resultCode, resultData);

        if (resultCode == DownloadService.UPDATE_PROGRESS) {

            int progress = resultData.getInt("progress"); //get the progress
            dialog.setProgress(progress);

            if (progress == 100) {
                dialog.dismiss();
            }
        }
    }
}

2.1 Use Groundy library

Groundy is a library that basically helps you run pieces of code in a background service, and it is based on the ResultReceiver concept shown above. This library is deprecated at the moment. This is how the whole code would look like:

The activity where you are showing the dialog...

public class MainActivity extends Activity {

    private ProgressDialog mProgressDialog;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        findViewById(R.id.btn_download).setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                String url = ((EditText) findViewById(R.id.edit_url)).getText().toString().trim();
                Bundle extras = new Bundler().add(DownloadTask.PARAM_URL, url).build();
                Groundy.create(DownloadExample.this, DownloadTask.class)
                        .receiver(mReceiver)
                        .params(extras)
                        .queue();

                mProgressDialog = new ProgressDialog(MainActivity.this);
                mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
                mProgressDialog.setCancelable(false);
                mProgressDialog.show();
            }
        });
    }

    private ResultReceiver mReceiver = new ResultReceiver(new Handler()) {
        @Override
        protected void onReceiveResult(int resultCode, Bundle resultData) {
            super.onReceiveResult(resultCode, resultData);
            switch (resultCode) {
                case Groundy.STATUS_PROGRESS:
                    mProgressDialog.setProgress(resultData.getInt(Groundy.KEY_PROGRESS));
                    break;
                case Groundy.STATUS_FINISHED:
                    Toast.makeText(DownloadExample.this, R.string.file_downloaded, Toast.LENGTH_LONG);
                    mProgressDialog.dismiss();
                    break;
                case Groundy.STATUS_ERROR:
                    Toast.makeText(DownloadExample.this, resultData.getString(Groundy.KEY_ERROR), Toast.LENGTH_LONG).show();
                    mProgressDialog.dismiss();
                    break;
            }
        }
    };
}

A GroundyTask implementation used by Groundy to download the file and show the progress:

public class DownloadTask extends GroundyTask {    
    public static final String PARAM_URL = "com.groundy.sample.param.url";

    @Override
    protected boolean doInBackground() {
        try {
            String url = getParameters().getString(PARAM_URL);
            File dest = new File(getContext().getFilesDir(), new File(url).getName());
            DownloadUtils.downloadFile(getContext(), url, dest, DownloadUtils.getDownloadListenerForTask(this));
            return true;
        } catch (Exception pokemon) {
            return false;
        }
    }
}

And just add this to the manifest:

<service android:name="com.codeslap.groundy.GroundyService"/>

It couldn't be easier I think. Just grab the latest jar from Github and you are ready to go. Keep in mind that Groundy's main purpose is to make calls to external REST apis in a background service and post results to the UI with easily. If you are doing something like that in your app, it could be really useful.

2.2 Use https://github.com/koush/ion

3. Use DownloadManager class (GingerBread and newer only)

GingerBread brought a new feature, DownloadManager, which allows you to download files easily and delegate the hard work of handling threads, streams, etc. to the system.

First, let's see a utility method:

/**
 * @param context used to check the device version and DownloadManager information
 * @return true if the download manager is available
 */
public static boolean isDownloadManagerAvailable(Context context) {

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
        return true;
    }
    return false;
}

Method's name explains it all. Once you are sure DownloadManager is available, you can do something like this:

String url = "url you want to download";
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setDescription("Some descrition");
request.setTitle("Some title");
// in order for this if to run, you must use the android 3.2 to compile your app
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
    request.allowScanningByMediaScanner();
    request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "name-of-the-file.ext");

// get download service and enqueue file
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);

Download progress will be showing in the notification bar.

Final thoughts

First and second methods are just the tip of the iceberg. There are lots of things you have to keep in mind if you want your app to be robust. Here is a brief list:

• You must check whether user has an internet connection available
• Make sure you have the right permissions (INTERNET and WRITE_EXTERNAL_STORAGE); also ACCESS_NETWORK_STATE if you want to check internet availability.
• Make sure the directory were you are going to download files exist and has write permissions.
• If download is too big you may want to implement a way to resume the download if previous attempts failed.
• Users will be grateful if you allow them to interrupt the download.

Unless you need detailed control of the download process, then consider using DownloadManager (3) because it already handles most of the items listed above.

But also consider that your needs may change. For example, DownloadManager does no response caching. It will blindly download the same big file multiple times. There's no easy way to fix it after the fact. Where if you start with a basic HttpURLConnection (1, 2), then all you need is to add an HttpResponseCache. So the initial effort of learning the basic, standard tools can be a good investment.

This class was deprecated in API level 26. ProgressDialog is a modal dialog, which prevents the user from interacting with the app. Instead of using this class, you should use a progress indicator like ProgressBar, which can be embedded in your app's UI. Alternatively, you can use a notification to inform the user of the task's progress. For more details Link

Both commands are correct

php_value post_max_size 30M 

php_value upload_max_filesize 30M 

BUT to use the .htaccess you have to enable rewrite_module in Apache config file. In httpd.conf find this line:

# LoadModule rewrite_module modules/mod_rewrite.so

and remove the #.

Using your code, this is how I would do it. I know an answer was chosen, just giving additional options.

data = json.loads('{"lat":444, "lon":555}')
    ret = ''
    for j in data:
        ret = ret+" "+data[j]
return ret

When you use for in this manor you get the key of the object, not the value, so you can get the value, by using the key as an index.

You can do something like this.

 List<Map<String, Object>> mapList = jdbctemplate.queryForList(query));
    return mapList.stream().collect(Collectors.toMap(k -> (Long) k.get("userid"), k -> (String) k.get("username")));

Output:

 {
  1: "abc",
  2: "def",
  3: "ghi"
}

var pass = new SecureString();
pass.AppendChar('s');
pass.AppendChar('e');
pass.AppendChar('c');
pass.AppendChar('r');
pass.AppendChar('e');
pass.AppendChar('t');
Process.Start("notepad", "admin", pass, "");

Works also with ProcessStartInfo:

var psi = new ProcessStartInfo
{
    FileName = "notepad",
    UserName = "admin",
    Domain = "",
    Password = pass,
    UseShellExecute = false,
    RedirectStandardOutput = true,
    RedirectStandardError = true
};
Process.Start(psi);

I review your url in use:

https://www.facebook.com/sharer/sharer.php?s=100&p[title]=EXAMPLE&p[summary]=EXAMPLE&p[url]=EXAMPLE&p[images][0]=EXAMPLE

and see this differences:

1. The sharer URL not is same.
2. The strings are in different order. ( Do not know if this affects ).

I use this URL string:

http://www.facebook.com/sharer.php?s=100&p[url]=http://www.example.com/&p[images][0]=/images/image.jpg&p[title]=Title&p[summary]=Summary

In the "title" and "summary" section, I use the php function urlencode(); like this:

<?php echo urlencode($detail->title); ?>

And working fine for me.

put your session() auth in all server side pages accepting an ajax request:

if(require_once("auth.php")) {

//run json code

}

// do nothing otherwise

that's about the only way I've ever done it.

Use PHP's popen command, e.g.:

pclose(popen("start c:\wamp\bin\php.exe c:\wamp\www\script.php","r"));

This will create a child process and the script will excute in the background without waiting for output.

.bashrc is not sourced when you log in using SSH. You need to source it in your .bash_profile like this:

if [ -f ~/.bashrc ]; then
  . ~/.bashrc
fi

Try Restarting the editor in which you are writing the code(VS code or Sublime). Compile and Run it again. I have done the same and it worked.

This happens when you add a new class outside from your editor or keep running your angular cli 'ng serve'. Actually your editor or the 'ng serve' command may not able to find the newly created files.

• the Id selector is used when referring to a single unique element.
• The Class selector referrers a group of elements.

For example, if you have a multiple buttons that look the same, you should use class="mybutton" to have consistent styling.

In terms of performance:

CSS selectors are matched from right to left.

Therefore, .myClass should be "faster" than #myID because it misses out testing.

The performance speed is negligible for normally sized pages and you will probably never notice a difference so it's mostly just about convention.

Here is more info on why css is browsers match css selectors from right to left

If you save the excel file as a CSV file then you can import it into a mysql database using tools such as PHPMyAdmin

Im not sure if this would help in your situation, but a csv file either manually or programatically would be a lot easier to parse into a database than an excel file I would have thought.

EDIT: I would however suggest looking at the other answers rather than mine since @diEcho answer seems more appropriate.

I use the following format and works well.

robocopy \\SourceServer\Path \\TargetServer\Path filename.txt

to copy everything you can replace filename.txt with *.* and there are plenty of other switches to copy subfolders etc... see here: http://ss64.com/nt/robocopy.html

This can happen with a 401 http response if using NSURLConnection.

See NSURLConnection returning error instead of response for 401

If you are using kotlin,consider these library. It's build for kotlin language.

AndroidHttpServer is a simple demo using ServerSocket to handle http request

AndroidHttpServer is very small , but the feature is less as well.

Ktor is a very nice library,and the usage is simple too

You can use a sprite which has both version—the colored and the monochrome—stored into it.

PHP does not have permissions to write on /tmp directory. You need to use chmod command to open /tmp permissions.

You need to use setInterval to trigger the change, but you also need to clear the timer when the component unmounts to prevent it leaving errors and leaking memory:

componentDidMount() {
  this.interval = setInterval(() => this.setState({ time: Date.now() }), 1000);
}
componentWillUnmount() {
  clearInterval(this.interval);
}

You could use WebView.loadDataWithBaseURL

htmlData = "<link rel=\"stylesheet\" type=\"text/css\" href=\"style.css\" />" + htmlData;
// lets assume we have /assets/style.css file
webView.loadDataWithBaseURL("file:///android_asset/", htmlData, "text/html", "UTF-8", null);

And only after that WebView will be able to find and use css-files from the assets directory.

ps And, yes, if you load your html-file form the assets folder, you don't need to specify a base url.

Just use format(number, qtyDecimals) sample: format(1000, 2) result 1000.00

string is synonym for System.String type, They are identical.

Values are also identical: string.Empty == String.Empty == ""

I would not use character constant "" in code, rather string.Empty or String.Empty - easier to see what programmer meant.

Between string and String I like lower case string more just because I used to work with Delphi for lot of years and Delphi style is lowercase string.

So, if I was your boss, you would be writing string.Empty

Just one extra option, if you want to revert the default behaviour for all textareas in the application, you could add the following to your CSS:

textarea:not([resize="true"]) {
  resize: none !important;
}

And do the following to enable where you want resizing:

<textarea resize="true"></textarea>

Have in mind this solution might not work in all browsers you may want to support. You can check the list of support for resize here: http://caniuse.com/#feat=css-resize

Rather than deleting, I think we can nullify the file, because the file will be created if the mail service is still on. Something like following will do the job

And yes, sorry for awakening this old thread but I felt I could contribute.

Use database field type BLOB to store arrays.

Ref: http://us.php.net/manual/en/function.serialize.php

Return Values

Returns a string containing a byte-stream representation of value that can be stored anywhere.

Note that this is a binary string which may include null bytes, and needs to be stored and handled as such. For example, serialize() output should generally be stored in a BLOB field in a database, rather than a CHAR or TEXT field.

The onunload event is not called in all browsers. Worse, you cannot check the return value of onbeforeunload event. That prevents us from actually preforming a logout function.

However, you can hack around this.

Call logout first thing in the onbeforeunload event. then prompt the user. If the user cancels their logout, automatically login them back in, by using the onfocus event. Kinda backwards, but I think it should work.

'use strict';

var reconnect = false;

window.onfocus = function () {
  if (reconnect) {
    reconnect = false;
    alert("Perform an auto-login here!");
  }
};

window.onbeforeunload = function () {
  //logout();
  var msg = "Are you sure you want to leave?";
  reconnect = true;
  return msg;
};

I use:

let dictionary = ["method":"login_user",
                  "cel":mobile.text!
                  "password":password.text!] as  Dictionary<String,String>

for (key, value) in dictionary {
    data=data+"&"+key+"="+value
    }

request.HTTPBody = data.dataUsingEncoding(NSUTF8StringEncoding);

This maven dependency will solve your problem:

One thing I've struggled is that for ZonedDateTime timezone being changed to GMT during deserialization. Turned out, that by default jackson replaces it with one from context.. To keep zone one must disable this 'feature'

Jackson2ObjectMapperBuilder.json()
    .featuresToDisable(DeserializationFeature.ADJUST_DATES_TO_CONTEXT_TIME_ZONE)

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

Those classes are common extension points for Java UI designs. First off, realize that they don't necessarily have much to do with each other directly, so trying to find a relationship between them might be counterproductive.

JApplet - A base class that let's you write code that will run within the context of a browser, like for an interactive web page. This is cool and all but it brings limitations which is the price for it playing nice in the real world. Normally JApplet is used when you want to have your own UI in a web page. I've always wondered why people don't take advantage of applets to store state for a session so no database or cookies are needed.

JComponent - A base class for objects which intend to interact with Swing.

JFrame - Used to represent the stuff a window should have. This includes borders (resizeable y/n?), titlebar (App name or other message), controls (minimize/maximize allowed?), and event handlers for various system events like 'window close' (permit app to exit yet?).

JPanel - Generic class used to gather other elements together. This is more important with working with the visual layout or one of the provided layout managers e.g. gridbaglayout, etc. For example, you have a textbox that is bigger then the area you have reserved. Put the textbox in a scrolling pane and put that pane into a JPanel. Then when you place the JPanel, it will be more manageable in terms of layout.

I like Guffa's answer and since I can't comment I will provide the answer Udil's question here.

I needed something similar but I wanted certein logic in my token, I wanted to:

1. See the expiration of a token
2. Use a guid to mask validate (global application guid or user guid)
3. See if the token was provided for the purpose I created it (no reuse..)
4. See if the user I send the token to is the user that I am validating it for

Now points 1-3 are fixed length so it was easy, here is my code:

Here is my code to generate the token:

public string GenerateToken(string reason, MyUser user)
{
    byte[] _time     = BitConverter.GetBytes(DateTime.UtcNow.ToBinary());
    byte[] _key      = Guid.Parse(user.SecurityStamp).ToByteArray();
    byte[] _Id       = GetBytes(user.Id.ToString());
    byte[] _reason   = GetBytes(reason);
    byte[] data       = new byte[_time.Length + _key.Length + _reason.Length+_Id.Length];

    System.Buffer.BlockCopy(_time, 0, data, 0, _time.Length);
    System.Buffer.BlockCopy(_key , 0, data, _time.Length, _key.Length);
    System.Buffer.BlockCopy(_reason, 0, data, _time.Length + _key.Length, _reason.Length);
    System.Buffer.BlockCopy(_Id, 0, data, _time.Length + _key.Length + _reason.Length, _Id.Length);

    return Convert.ToBase64String(data.ToArray());
}

Here is my Code to take the generated token string and validate it:

public TokenValidation ValidateToken(string reason, MyUser user, string token)
{
    var result = new TokenValidation();
    byte[] data     = Convert.FromBase64String(token);
    byte[] _time     = data.Take(8).ToArray();
    byte[] _key      = data.Skip(8).Take(16).ToArray();
    byte[] _reason   = data.Skip(24).Take(2).ToArray();
    byte[] _Id       = data.Skip(26).ToArray();

    DateTime when = DateTime.FromBinary(BitConverter.ToInt64(_time, 0));
    if (when < DateTime.UtcNow.AddHours(-24))
    {
        result.Errors.Add( TokenValidationStatus.Expired);
    }
    
    Guid gKey = new Guid(_key);
    if (gKey.ToString() != user.SecurityStamp)
    {
        result.Errors.Add(TokenValidationStatus.WrongGuid);
    }

    if (reason != GetString(_reason))
    {
        result.Errors.Add(TokenValidationStatus.WrongPurpose);
    }

    if (user.Id.ToString() != GetString(_Id))
    {
        result.Errors.Add(TokenValidationStatus.WrongUser);
    }
    
    return result;
}

private static string GetString(byte[] reason) => Encoding.ASCII.GetString(reason);

private static byte[] GetBytes(string reason) => Encoding.ASCII.GetBytes(reason);

The TokenValidation class looks like this:

public class TokenValidation
{
    public bool Validated { get { return Errors.Count == 0; } }
    public readonly List<TokenValidationStatus> Errors = new List<TokenValidationStatus>();
}

public enum TokenValidationStatus
{
    Expired,
    WrongUser,
    WrongPurpose,
    WrongGuid
}

Now I have an easy way to validate a token, no Need to Keep it in a list for 24 hours or so. Here is my Good-Case Unit test:

private const string ResetPasswordTokenPurpose = "RP";
private const string ConfirmEmailTokenPurpose  = "EC";//change here change bit length for reason  section (2 per char)

[TestMethod]
public void GenerateTokenTest()
{
    MyUser user         = CreateTestUser("name");
    user.Id             = 123;
    user.SecurityStamp  = Guid.NewGuid().ToString();
    var token   = sit.GenerateToken(ConfirmEmailTokenPurpose, user);
    var validation    = sit.ValidateToken(ConfirmEmailTokenPurpose, user, token);
    Assert.IsTrue(validation.Validated,"Token validated for user 123");
}

One can adapt the code for other business cases easely.

Happy Coding

Walter

On my Mac that I'm sure I'm not going to allow java anyplace other than a specific site, I was able to use Preferences->Java to bring up the Java control panel and turned the checking off. If DLink ever fixes their certificate, I'll turn it back on.

Someone with a requirement where they have to read from bits, lets say you have to read from only 3 bits but you need signed integer then use following:

data is of type: java.util.BitSet

new BigInteger(data.toByteArray).intValue() << 32 - 3 >> 32 - 3

The magic number 3 can be replaced with the number of bits (not bytes) you are using.

tl;dr

what is the way to retrieve a Date object so that its always in GMT?

Instant.now() 

Details

You are using troublesome confusing old date-time classes that are now supplanted by the java.time classes.

Instant = UTC

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = Instant.now() ; // Current moment in UTC.

ISO 8601

To exchange this data as text, use the standard ISO 8601 formats exclusively. These formats are sensibly designed to be unambiguous, easy to process by machine, and easy to read across many cultures by people.

The java.time classes use the standard formats by default when parsing and generating strings.

String output = instant.toString() ;  

2017-01-23T12:34:56.123456789Z

Time zone

If you want to see that same moment as presented in the wall-clock time of a particular region, apply a ZoneId to get a ZonedDateTime.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "Asia/Singapore" ) ;
ZonedDateTime zdt = instant.atZone( z ) ;  // Same simultaneous moment, same point on the timeline.

See this code live at IdeOne.com.

Notice the eight hour difference, as the time zone of Asia/Singapore currently has an offset-from-UTC of +08:00. Same moment, different wall-clock time.

instant.toString(): 2017-01-23T12:34:56.123456789Z

zdt.toString(): 2017-01-23T20:34:56.123456789+08:00[Asia/Singapore]

Convert

Avoid the legacy java.util.Date class. But if you must, you can convert. Look to new methods added to the old classes.

java.util.Date date = Date.from( instant ) ;

…going the other way…

Instant instant = myJavaUtilDate.toInstant() ;

Date-only

For date-only, use LocalDate.

LocalDate ld = zdt.toLocalDate() ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

outlist <- list(resultsa)
outlist[2] <- list(resultsb)
outlist[3] <- list(resultsc)

append's help file says it is for vectors. But it can be used here. I thought I had tried that before but there were some strange anomalies in the OP's code that may have mislead me:

outlist <- list(resultsa)
outlist <- append(outlist,list(resultsb))
outlist <- append(outlist,list(resultsc))

Same results.

The one answer is fine but requires a little reading into. Especially with the new terminology "stop".

My Go -- organized by differences to make it useful in addition to the first answer by Daniel above:

1) negative indexes. Substring requires positive indexes and will set a negative index to 0. Slice's negative index means the position from the end of the string.

"1234".substring(-2, -1) == "1234".substring(0,0) == ""
"1234".slice(-2, -1) == "1234".slice(2, 3) == "3"

2) Swapping of indexes. Substring will reorder the indexes to make the first index less than or equal to the second index.

"1234".substring(3,2) == "1234".substring(2,3) == "3"
"1234".slice(3,2) == ""

--------------------------

General comment -- I find it weird that the second index is the position after the last character of the slice or substring. I would expect "1234".slice(2,2) to return "3". This makes Andy's confusion above justified -- I would expect "1234".slice(2, -1) to return "34". Yes, this means I'm new to Javascript. This means also this behavior:

"1234".slice(-2, -2) == "", "1234".slice(-2, -1) == "3", "1234".slice(-2, -0) == "" <-- you have to use length or omit the argument to get the 4.
"1234".slice(3, -2) == "", "1234".slice(3, -1) == "", "1234".slice(3, -0) == "" <-- same issue, but seems weirder.

My 2c.

"If you start an android Service with startService(..) that Service will remain running until you explicitly invoke stopService(..). There are two reasons that a service can be run by the system. If someone calls Context.startService() then the system will retrieve the service (creating it and calling its onCreate() method if needed) and then call its onStartCommand(Intent, int, int) method with the arguments supplied by the client. The service will at this point continue running until Context.stopService() or stopSelf() is called. Note that multiple calls to Context.startService() do not nest (though they do result in multiple corresponding calls to onStartCommand()), so no matter how many times it is started a service will be stopped once Context.stopService() or stopSelf() is called; however, services can use their stopSelf(int) method to ensure the service is not stopped until started intents have been processed.

Clients can also use Context.bindService() to obtain a persistent connection to a service. This likewise creates the service if it is not already running (calling onCreate() while doing so), but does not call onStartCommand(). The client will receive the IBinder object that the service returns from its onBind(Intent) method, allowing the client to then make calls back to the service. The service will remain running as long as the connection is established (whether or not the client retains a reference on the Service's IBinder). Usually the IBinder returned is for a complex interface that has been written in AIDL.

A service can be both started and have connections bound to it. In such a case, the system will keep the service running as long as either it is started or there are one or more connections to it with the Context.BIND_AUTO_CREATE flag. Once neither of these situations hold, the Service's onDestroy() method is called and the service is effectively terminated. All cleanup (stopping threads, unregistering receivers) should be complete upon returning from onDestroy()."

You can do this:

([0-9]+) (\([^)]+\))? Z

This will not work with nested parens for Y, however. Nesting requires recursion which isn't strictly regular any more (but context-free). Modern regexp engines can still handle it, albeit with some difficulties (back-references).

{{ (ability.id in company_abilities) ? 'selected' : '' }}

The ternary operator is documented under 'other operators'

Another option is to use InjectableValues and @JacksonInject. It is very useful if you need to use not always the same value but one get from DB or somewhere else for the specific case. Here is an example of using JacksonInject:

protected static class Some {
    private final String field1;
    private final String field2;

    public Some(@JsonProperty("field1") final String field1,
            @JsonProperty("field2") @JacksonInject(value = "defaultValueForField2",
                    useInput = OptBoolean.TRUE) final String field2) {
        this.field1 = requireNonNull(field1);
        this.field2 = requireNonNull(field2);
    }

    public String getField1() {
        return field1;
    }

    public String getField2() {
        return field2;
    }
}

@Test
public void testReadValueInjectables() throws JsonParseException, JsonMappingException, IOException {
    final ObjectMapper mapper = new ObjectMapper();
    final InjectableValues injectableValues =
            new InjectableValues.Std().addValue("defaultValueForField2", "somedefaultValue");
    mapper.setInjectableValues(injectableValues);

    final Some actualValueMissing = mapper.readValue("{\"field1\": \"field1value\"}", Some.class);
    assertEquals(actualValueMissing.getField1(), "field1value");
    assertEquals(actualValueMissing.getField2(), "somedefaultValue");

    final Some actualValuePresent =
            mapper.readValue("{\"field1\": \"field1value\", \"field2\": \"field2value\"}", Some.class);
    assertEquals(actualValuePresent.getField1(), "field1value");
    assertEquals(actualValuePresent.getField2(), "field2value");
}

Keep in mind that if you are using constructor to create the entity (this usually happens when you use @Value or @AllArgsConstructor in lombok ) and you put @JacksonInject not to the constructor but to the property it will not work as expected - value of the injected field will always override value in json, no matter whether you put useInput = OptBoolean.TRUE in @JacksonInject. This is because jackson injects those properties after constructor is called (even if the property is final) - field is set to the correct value in constructor but then it is overrided (check: https://github.com/FasterXML/jackson-databind/issues/2678 and https://github.com/rzwitserloot/lombok/issues/1528#issuecomment-607725333 for more information), this test is unfortunately passing:

protected static class Some {
    private final String field1;

    @JacksonInject(value = "defaultValueForField2", useInput = OptBoolean.TRUE)
    private final String field2;

    public Some(@JsonProperty("field1") final String field1,
            @JsonProperty("field2") @JacksonInject(value = "defaultValueForField2",
                    useInput = OptBoolean.TRUE) final String field2) {
        this.field1 = requireNonNull(field1);
        this.field2 = requireNonNull(field2);
    }

    public String getField1() {
        return field1;
    }

    public String getField2() {
        return field2;
    }
}

@Test
public void testReadValueInjectablesIncorrectBehavior() throws JsonParseException, JsonMappingException, IOException {
    final ObjectMapper mapper = new ObjectMapper();
    final InjectableValues injectableValues =
            new InjectableValues.Std().addValue("defaultValueForField2", "somedefaultValue");
    mapper.setInjectableValues(injectableValues);

    final Some actualValueMissing = mapper.readValue("{\"field1\": \"field1value\"}", Some.class);
    assertEquals(actualValueMissing.getField1(), "field1value");
    assertEquals(actualValueMissing.getField2(), "somedefaultValue");

    final Some actualValuePresent =
            mapper.readValue("{\"field1\": \"field1value\", \"field2\": \"field2value\"}", Some.class);
    assertEquals(actualValuePresent.getField1(), "field1value");
    // unfortunately "field2value" is overrided because of putting "@JacksonInject" to the field
    assertEquals(actualValuePresent.getField2(), "somedefaultValue");
}

Hope this helps to someone with a similar problem.

P.S. I'm using jackson v. 2.9.6

gethostname() is POSIX way to get local host name. Check out man.

BSD function getdomainname() can give you domain name so you can build fully qualified hostname. There is no POSIX way to get a domain I'm afraid.

Maybe it's useful to someone: After converting my app to MVC 4 with .NET framework 4.5 and installing the framework on my server with IIS 7.0 I encountered the same 'forbidden' error mentioned in the question. I tried all options described above to no avail, when I noticed the

<system.webServer>
 <modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>

was missing from my web.config. After adding this, everything worked. Simple, but easy to overlook...

EDIT:

Of course the solution above will work, but it is indeed a waste of resources. I think it is better to add the routing module as pointed out by Chris Herring in the comments.

<system.webServer>
  <modules>
    <remove name="UrlRoutingModule-4.0" />
    <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
  </modules>
</system.webServer>

in batch file abc.bat

cd c:\user\ben_dchost\documents\
executible.exe -flag1 -flag2 -flag3 

I am assuming that your executible.exe is present in c:\user\ben_dchost\documents\ I am also assuming that the parameters it takes are -flag1 -flag2 -flag3

Edited:

For the command you say you want to execute, do:

cd C:\Users\Ben\Desktop\BGInfo\
bginfo.exe dc_bginfo.bgi
pause

Hope this helps

I had the same problem but got round it by setting AutoPostBack to true and in an update panel set the trigger to the dropdownlist control id and event name to SelectedIndexChanged e.g.

    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" enableViewState="true">
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="ddl1" EventName="SelectedIndexChanged" />
        </Triggers>
        <ContentTemplate>
            <asp:DropDownList ID="ddl1" runat="server" ClientIDMode="Static" OnSelectedIndexChanged="ddl1_SelectedIndexChanged" AutoPostBack="true" ViewStateMode="Enabled">
                <asp:ListItem Text="--Please select a item--" Value="0" />
            </asp:DropDownList>
        </ContentTemplate>
    </asp:UpdatePanel>

The first parameter to the iterator in forEach is the value and second is the key of the object.

angular.forEach(objectToIterate, function(value, key) {
    /* do something for all key: value pairs */
});

In your example, the outer forEach is actually:

angular.forEach($scope.filters, function(filterObj , filterKey)

Use the PercentRelativeLayout or PercentFrameLayout from the Percent Supoort Library

<android.support.percent.PercentFrameLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
     <TextView
          android:layout_width="match_parent"
          app:layout_heightPercent="68%"/>
     <Gallery 
          android:id="@+id/gallery"
          android:layout_width="match_parent"
          app:layout_heightPercent="16%"/>
     <TextView
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:layout_width="match_parent"/>
</android.support.percent.PercentFrameLayout>

You can use code as below when

using Image as Loading

<asp:UpdateProgress id="updateProgress" runat="server">
    <ProgressTemplate>
        <div style="position: fixed; text-align: center; height: 100%; width: 100%; top: 0; right: 0; left: 0; z-index: 9999999; background-color: #000000; opacity: 0.7;">
            <asp:Image ID="imgUpdateProgress" runat="server" ImageUrl="~/images/ajax-loader.gif" AlternateText="Loading ..." ToolTip="Loading ..." style="padding: 10px;position:fixed;top:45%;left:50%;" />
        </div>
    </ProgressTemplate>
</asp:UpdateProgress>

using Text as Loading

<asp:UpdateProgress id="updateProgress" runat="server">
    <ProgressTemplate>
        <div style="position: fixed; text-align: center; height: 100%; width: 100%; top: 0; right: 0; left: 0; z-index: 9999999; background-color: #000000; opacity: 0.7;">
            <span style="border-width: 0px; position: fixed; padding: 50px; background-color: #FFFFFF; font-size: 36px; left: 40%; top: 40%;">Loading ...</span>
        </div>
    </ProgressTemplate>
</asp:UpdateProgress>

A good reason is for security - this can prevent CSRF attacks because this header cannot be added to the AJAX request cross domain without the consent of the server via CORS.

Only the following headers are allowed cross domain:

• Accept
• Accept-Language
• Content-Language
• Last-Event-ID
• Content-Type

any others cause a "pre-flight" request to be issued in CORS supported browsers.

Without CORS it is not possible to add X-Requested-With to a cross domain XHR request.

If the server is checking that this header is present, it knows that the request didn't initiate from an attacker's domain attempting to make a request on behalf of the user with JavaScript. This also checks that the request wasn't POSTed from a regular HTML form, of which it is harder to verify it is not cross domain without the use of tokens. (However, checking the Origin header could be an option in supported browsers, although you will leave old browsers vulnerable.)

New Flash bypass discovered

You may wish to combine this with a token, because Flash running on Safari on OSX can set this header if there's a redirect step. It appears it also worked on Chrome, but is now remediated. More details here including different versions affected.

OWASP Recommend combining this with an Origin and Referer check:

This defense technique is specifically discussed in section 4.3 of Robust Defenses for Cross-Site Request Forgery. However, bypasses of this defense using Flash were documented as early as 2008 and again as recently as 2015 by Mathias Karlsson to exploit a CSRF flaw in Vimeo. But, we believe that the Flash attack can't spoof the Origin or Referer headers so by checking both of them we believe this combination of checks should prevent Flash bypass CSRF attacks. (NOTE: If anyone can confirm or refute this belief, please let us know so we can update this article)

However, for the reasons already discussed checking Origin can be tricky.

Update

Written a more in depth blog post on CORS, CSRF and X-Requested-With here.

Here is what I ended up using

$ipaddress = $(ipconfig | where {$_ -match 'IPv4.+\s(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})' } | out-null; $Matches[1])

which breaks down as

• execute ipconfig command - get all the network interface information
• use powershell's where filter with a regular expression
• regular expression finds the line with "IPv4" and a set of 4 blocks each with 1-3 digits separated by periods, i.e. a v4 IP address
• disregard the output by piping it to null
• finally get the first matched group as defined by the brackets in the regular expression.
• catch that output in $ipaddress for later use.

String.Replace('\n', '') doesn't work because '' is not a valid character literal.

If you use the String.Replace(string, string) override, it should work.

string temp = mystring.Replace("\n", "");

Your font tag is not correct, so it won't work in some browsers. The px unit is used with CSS, not HTML attributes. The font tag should look like this:

<font size="100">

Well, actually it shouldn't be there at all. The font tag is deprecated, you should use CSS to style the content, like you do already with the text-decoration:

<a href="selectTopic?html" style="font-size: 100px; text-decoration: none">HTML 5</a>

To separate the content from the styling, you should of course work towards putting the CSS in a style sheet rather than as inline style attributes. That way you can apply one style to several elements without having to put the same style attribute in all of them.

Example:

<a href="selectTopic?html" class="topic">HTML 5</a>

CSS:

.topic { font-size: 100px; text-decoration: none; }

This solution works for multiline:

After following several articles, and requiring a function that would automatically scale the text and adjust the line count to best fit within the given label size, I wrote a function myself. (ie. a short string would fit nicely on one line and use a large amount of the label frame, whereas a long strong would automatically split onto 2 or 3 lines and adjust the size accordingly)

Feel free to re-use it and tweak as required. Make sure you call it after viewDidLayoutSubviews has finished so that the initial label frame has been set.

+ (void)setFontForLabel:(UILabel *)label withMaximumFontSize:(float)maxFontSize andMaximumLines:(int)maxLines {
    int numLines = 1;
    float fontSize = maxFontSize;
    CGSize textSize; // The size of the text
    CGSize frameSize; // The size of the frame of the label
    CGSize unrestrictedFrameSize; // The size the text would be if it were not restricted by the label height
    CGRect originalLabelFrame = label.frame;

    frameSize = label.frame.size;
    textSize = [label.text sizeWithAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize: fontSize]}];

    // Work out the number of lines that will need to fit the text in snug
    while (((textSize.width / numLines) / (textSize.height * numLines) > frameSize.width / frameSize.height) && (numLines < maxLines)) {
        numLines++;
    }

    label.numberOfLines = numLines;

    // Get the current text size
    label.font = [UIFont systemFontOfSize:fontSize];
    textSize = [label.text boundingRectWithSize:CGSizeMake(frameSize.width, CGFLOAT_MAX)
                                        options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
                                     attributes:@{NSFontAttributeName : label.font}
                                        context:nil].size;

    // Adjust the frame size so that it can fit text on more lines
    // so that we do not end up with truncated text
    label.frame = CGRectMake(label.frame.origin.x, label.frame.origin.y, label.frame.size.width, label.frame.size.width);

    // Get the size of the text as it would fit into the extended label size
    unrestrictedFrameSize = [label textRectForBounds:CGRectMake(0, 0, label.bounds.size.width, CGFLOAT_MAX) limitedToNumberOfLines:numLines].size;

    // Keep reducing the font size until it fits
    while (textSize.width > unrestrictedFrameSize.width || textSize.height > frameSize.height) {
        fontSize--;
        label.font = [UIFont systemFontOfSize:fontSize];
        textSize = [label.text boundingRectWithSize:CGSizeMake(frameSize.width, CGFLOAT_MAX)
                                            options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
                                         attributes:@{NSFontAttributeName : label.font}
                                            context:nil].size;
        unrestrictedFrameSize = [label textRectForBounds:CGRectMake(0, 0, label.bounds.size.width, CGFLOAT_MAX) limitedToNumberOfLines:numLines].size;
    }

    // Set the label frame size back to original
    label.frame = originalLabelFrame;
}

I just tried SMTPop and it worked.

1. I downloaded this.
2. Added smtpop.dll reference to my C# .NET project

Wrote the following code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;    
using SmtPop;

namespace SMT_POP3 {

    class Program {
        static void Main(string[] args) {
            SmtPop.POP3Client pop = new SmtPop.POP3Client();
            pop.Open("<hostURL>", 110, "<username>", "<password>");

            // Get message list from POP server
            SmtPop.POPMessageId[] messages = pop.GetMailList();
            if (messages != null) {

                // Walk attachment list
                foreach(SmtPop.POPMessageId id in messages) {
                    SmtPop.POPReader reader= pop.GetMailReader(id);
                    SmtPop.MimeMessage msg = new SmtPop.MimeMessage();

                    // Read message
                    msg.Read(reader);
                    if (msg.AddressFrom != null) {
                        String from= msg.AddressFrom[0].Name;
                        Console.WriteLine("from: " + from);
                    }
                    if (msg.Subject != null) {
                        String subject = msg.Subject;
                        Console.WriteLine("subject: "+ subject);
                    }
                    if (msg.Body != null) {
                        String body = msg.Body;
                        Console.WriteLine("body: " + body);
                    }
                    if (msg.Attachments != null && false) {
                        // Do something with first attachment
                        SmtPop.MimeAttachment attach = msg.Attachments[0];

                        if (attach.Filename == "data") {
                           // Read data from attachment
                           Byte[] b = Convert.FromBase64String(attach.Body);
                           System.IO.MemoryStream mem = new System.IO.MemoryStream(b, false);

                           //BinaryFormatter f = new BinaryFormatter();
                           // DataClass data= (DataClass)f.Deserialize(mem); 
                           mem.Close();
                        }                     

                        // Delete message
                        // pop.Dele(id.Id);
                    }
               }
           }    
           pop.Quit();
        }
    }
}

Even if your data falls within your specified limits (e.g. c(0, 335)), adding a geom_jitter() statement could push some points outside those limits, producing the same error message.

library(ggplot2)

range(mtcars$hp)
#> [1]  52 335

# No jitter -- no error message
ggplot(mtcars, aes(mpg, hp)) + 
    geom_point() +
    scale_y_continuous(limits=c(0,335))


# Jitter is too large -- this generates the error message
ggplot(mtcars, aes(mpg, hp)) + 
    geom_point() +
    geom_jitter(position = position_jitter(w = 0.2, h = 0.2)) +
    scale_y_continuous(limits=c(0,335))
#> Warning: Removed 1 rows containing missing values (geom_point).

There is no difference between the two, one is just a shorthand for the second.

The v- prefix serves as a visual cue for identifying Vue-specific attributes in your templates. This is useful when you are using Vue.js to apply dynamic behavior to some existing markup, but can feel verbose for some frequently used directives. At the same time, the need for the v- prefix becomes less important when you are building an SPA where Vue.js manages every template.

If you want to call an action from your JavaScript, one way is to embed your JavaScript code, inside your view (.cshtml file for example), and then, use Razor, to create a URL of that action:

$(function(){
    $('#sampleDiv').click(function(){

Nobody has explained the difference between ExceptionDispatchInfo.Capture( ex ).Throw() and a plain throw, so here it is. However, some people have noticed the problem with throw.

The complete way to rethrow a caught exception is to use ExceptionDispatchInfo.Capture( ex ).Throw() (only available from .Net 4.5).

Below there are the cases necessary to test this:

1.

void CallingMethod()
{
    //try
    {
        throw new Exception( "TEST" );
    }
    //catch
    {
    //    throw;
    }
}

2.

void CallingMethod()
{
    try
    {
        throw new Exception( "TEST" );
    }
    catch( Exception ex )
    {
        ExceptionDispatchInfo.Capture( ex ).Throw();
        throw; // So the compiler doesn't complain about methods which don't either return or throw.
    }
}

3.

void CallingMethod()
{
    try
    {
        throw new Exception( "TEST" );
    }
    catch
    {
        throw;
    }
}

4.

void CallingMethod()
{
    try
    {
        throw new Exception( "TEST" );
    }
    catch( Exception ex )
    {
        throw new Exception( "RETHROW", ex );
    }
}

Case 1 and case 2 will give you a stack trace where the source code line number for the CallingMethod method is the line number of the throw new Exception( "TEST" ) line.

However, case 3 will give you a stack trace where the source code line number for the CallingMethod method is the line number of the throw call. This means that if the throw new Exception( "TEST" ) line is surrounded by other operations, you have no idea at which line number the exception was actually thrown.

Case 4 is similar with case 2 because the line number of the original exception is preserved, but is not a real rethrow because it changes the type of the original exception.

To improve upon the answer with the most upticks, some of you may have noticed on the initial load of the page that the chevrons all point in the same direction. This is corrected by adding the class "collapsed" to elements that you want to load collapsed.

Here is a working fiddle: http://jsfiddle.net/3gYa3/585/

Just a small improvement to leoj3n's solution (to make the console window disappear): instead of putting %windir%\system32\cmd.exe /c start "" "%CD%\bat\bat\run.bat" to the Target: field of your Windows shortcut, you can also try adding only the following: %windir%\system32\cmd.exe /c "%CD%\bat\bat\run.bat" AND then also adding start in front of your commands in run.bat. That will make the console window disappear, but everything else remains the same.

Please think really hard about if you do need to kill the application: why not let the OS figure out where and when to free the resources?

Otherwise, if you're absolutely really sure, use

finish();

As a reaction to @dave appleton's comment: First thing read the big question/answer combo @gabriel posted: Is quitting an application frowned upon?

Now assuming we have that, the question here still has an answer, being that the code you need if you are doing anything with quitting is finish(). Obviously you can have more than one activity etc etc, but that's not the point. Lets run by some of the use-cases

1. You want to let the user quit everything because of memory usage and "not running in the background? Doubtfull. Let the user stop certain activities in the background, but let the OS kill any unneeded recourses.
2. You want a user to not go to the previous activity of your app? Well, either configure it so it doesn't, or you need an extra option. If most of the time the back=previous-activity works, wouldn't the user just press home if he/she wants to do something else?
3. If you need some sort of reset, you can find out if/how/etc your application was quit, and if your activity gets focus again you can take action on that, showing a fresh screen instead of restarting where you were.

So in the end, ofcourse, finish() doesn't kill everthing, but it is still the tool you need I think. If there is a usecase for "kill all activities", I haven't found it yet.

this some kind of late but anyway and it is also somewhat tricky

 dim arrr 
  arr= array ("Apples", "Oranges", "Bananas")
 dim temp_var 
 temp_var = join (arr , "||") ' some character which will not occur is regular strings 
 if len(temp_var) > 0 then 
  temp_var = temp_var&"||Watermelons" 
end if 
arr  = split(temp_var , "||") ' here you got new elemet in array ' 
for each x in arr
response.write(x & "<br />")
next' 

review and tell me if this can work or initially you save all data in string and later split for array

The question title is too wide and the author's need is more specific. In my case, I needed to extract all elements from nested list like in the example below:

Example:

input -> [1,2,[3,4]]
output -> [1,2,3,4]

The code below gives me the result, but I would like to know if anyone can create a simpler answer:

def get_elements_from_nested_list(l, new_l):
    if l is not None:
        e = l[0]
        if isinstance(e, list):
            get_elements_from_nested_list(e, new_l)
        else:
            new_l.append(e)
        if len(l) > 1:
            return get_elements_from_nested_list(l[1:], new_l)
        else:
            return new_l

Call of the method

l = [1,2,[3,4]]
new_l = []

get_elements_from_nested_list(l, new_l)

You need to write the ftp commands in a text file and give it as a parameter for the ftp command like this:

I am not sure though if it would work with username and password prompt.

i used the empty div solution, with this CSS:

#throbber {
    background-image: url(/Content/pictures/ajax-loader.gif);
    background-repeat: no-repeat;
    width: 48px;
    height: 48px;
    min-width: 48px;
    min-height: 48px;
}

HTML:

<div id="throbber"></div>

In most cases simply switching the virtual machine network adapter to bridged mode is enough to make the guest machine accessible from outside.

Sometimes it's possible for the guest machine to not automatically receive an IP which matches the host's IP range after switching to bridged mode (even after rebooting the guest machine). This is often caused by a malfunctioning or badly configured DHCP on the host network.

For example, if the host IP is 192.168.1.1 the guest machine needs to have an IP in the format 192.168.1.* where only the last group of numbers is allowed to be different from the host IP.

You can use a terminal (shell) and type ifconfig (ipconfig for Windows guests) to check what IP is assigned to the guest machine and change it if required.

If the host and guest IPs do not match simply setting a static IP for the guest machine explicitly should resolve the issue.

Here is the code to clean file name in python.

import unicodedata

def clean_name(name, replace_space_with=None):
    """
    Remove invalid file name chars from the specified name

    :param name: the file name
    :param replace_space_with: if not none replace space with this string
    :return: a valid name for Win/Mac/Linux
    """

    # ref: https://en.wikipedia.org/wiki/Filename
    # ref: https://stackoverflow.com/questions/4814040/allowed-characters-in-filename
    # No control chars, no: /, \, ?, %, *, :, |, ", <, >

    # remove control chars
    name = ''.join(ch for ch in name if unicodedata.category(ch)[0] != 'C')

    cleaned_name = re.sub(r'[/\\?%*:|"<>]', '', name)
    if replace_space_with is not None:
        return cleaned_name.replace(' ', replace_space_with)
    return cleaned_name

You can do it with a little bit of refactoring:

public class MySQLDatabaseConnectionFactory implements DatabaseConnectionFactory {

    @Override public Connection getConnection() {
        try {
            return _getConnection(...some params...);
        } catch (SQLException e) {
            throw new RuntimeException(e);
        }
    }

    //method to forward parameters, enabling mocking, extension, etc
    Connection _getConnection(...some params...) throws SQLException {
        return DriverManager.getConnection(...some params...);
    }
}

Then you can extend your class MySQLDatabaseConnectionFactory to return a mocked connection, do assertions on the parameters, etc.

The extended class can reside within the test case, if it's located in the same package (which I encourage you to do)

public class MockedConnectionFactory extends MySQLDatabaseConnectionFactory {

    Connection _getConnection(...some params...) throws SQLException {
        if (some param != something) throw new InvalidParameterException();

        //consider mocking some methods with when(yourMock.something()).thenReturn(value)
        return Mockito.mock(Connection.class);
    }
}

Please try this:

$uri = $_SERVER['REQUEST_URI']; // $uri == example.com/sub
$exploded_uri = explode('/', $uri); //$exploded_uri == array('example.com','sub')
$domain_name = $exploded_uri[1]; //$domain_name = 'example.com'

I hope this will help you.

you should do as:

getline(name, sizeofname, '\n');
strtok(name, " ");

This will give you the "joht" in name then to get next token,

temp = strtok(NULL, " ");

temp will get "smith" in it. then you should use string concatination to append the temp at end of name. as:

strcat(name, temp);

(you may also append space first, to obtain a space in between).

scp is best for one file.
OR a combination of tar & compression for smaller data sets like source code trees with small resources (ie: images, sqlite etc).

• media folders (40 GB)
• database backups (28 GB)
• mp3 libraries (100 GB)

It becomes impractical to build a zip/tar.gz file to transfer with scp at this point do to the physical limits of the hosted server.

As an exercise, you can do some gymnastics like piping tar into ssh and redirecting the results into a remote file. (saving the need to build a swap or temporary clone aka zip or tar.gz)

However,

rsync simplify's this process and allows you to transfer data without consuming any additional disc space.

Also,

Continuous (cron?) updates use minimal changes vs full cloned copies speed up large data migrations over time.

tl;dr
scp == small scale (with room to build compressed files on the same drive)
rsync == large scale (with the necessity to backup large data and no room left)

find . -type d -exec sh -c "echo -n {}; echo -n ' x '; echo {}" \;

I would try to solve this without VBA. Just select this space and use replace (change to nothing) on that worksheet you're trying to get rid off those spaces.

If you really want to use VBA I believe you could select first character

strSpace = left(range("A1").Value,1)

and use replace function in VBA the same way

Range("A1").Value = Replace(Range("A1").Value, strSpace, "")

or

for each cell in selection.cells
 cell.value = replace(cell.value, strSpace, "")
next

A small static custom method in a Util class would help:

 public static int getIndex(Set<? extends Object> set, Object value) {
   int result = 0;
   for (Object entry:set) {
     if (entry.equals(value)) return result;
     result++;
   }
   return -1;
 }

If you need/want one class that is a Set and offers a getIndex() method, I strongly suggest to implement a new Set and use the decorator pattern:

 public class IndexAwareSet<T> implements Set {
   private Set<T> set;
   public IndexAwareSet(Set<T> set) {
     this.set = set;
   }

   // ... implement all methods from Set and delegate to the internal Set

   public int getIndex(T entry) {
     int result = 0;
     for (T entry:set) {
       if (entry.equals(value)) return result;
       result++;
     }
     return -1;
   }
 }

Just a little note - this approach:

Task<Customer> task = GetCustomers();
task.Wait()

works for WinRT.

Let me explain:

private void TestMethod()
{
    Task<Customer> task = GetCustomers(); // call async method as sync and get task as result
    task.Wait(); // wait executing the method
    var customer = task.Result; // get's result.
    Debug.WriteLine(customer.Name); //print customer name
}
public class Customer
{
    public Customer()
    {
        new ManualResetEvent(false).WaitOne(TimeSpan.FromSeconds(5));//wait 5 second (long term operation)
    }
    public string Name { get; set; }
}
private Task<Customer> GetCustomers()
{
    return Task.Run(() => new Customer
    {
        Name = "MyName"
    });
}

Moreover this approach works for Windows Store solutions only!

Note: This way isn't thread safe if you call your method inside of other async method (according to comments of @Servy)

They all do different things, since matplotlib uses a hierarchical order in which a figure window contains a figure which may consist of many axes. Additionally, there are functions from the pyplot interface and there are methods on the Figure class. I will discuss both cases below.

pyplot interface

pyplot is a module that collects a couple of functions that allow matplotlib to be used in a functional manner. I here assume that pyplot has been imported as import matplotlib.pyplot as plt. In this case, there are three different commands that remove stuff:

plt.cla() clears an axes, i.e. the currently active axes in the current figure. It leaves the other axes untouched.

plt.clf() clears the entire current figure with all its axes, but leaves the window opened, such that it may be reused for other plots.

plt.close() closes a window, which will be the current window, if not specified otherwise.

Which functions suits you best depends thus on your use-case.

The close() function furthermore allows one to specify which window should be closed. The argument can either be a number or name given to a window when it was created using figure(number_or_name) or it can be a figure instance fig obtained, i.e., usingfig = figure(). If no argument is given to close(), the currently active window will be closed. Furthermore, there is the syntax close('all'), which closes all figures.

methods of the Figure class

Additionally, the Figure class provides methods for clearing figures. I'll assume in the following that fig is an instance of a Figure:

fig.clf() clears the entire figure. This call is equivalent to plt.clf() only if fig is the current figure.

fig.clear() is a synonym for fig.clf()

Note that even del fig will not close the associated figure window. As far as I know the only way to close a figure window is using plt.close(fig) as described above.

To modify an image proportionally, simply only alter one of the width/height css properties, leave the other set to auto.

image.style.width = '50%'
image.style.height = 'auto'

This will ensure that its aspect ratio remains the same.

Bear in mind that browsers tend to suck at resizing images nicely - you'll probably find that your resized image looks horrible.

Use the following Syntax

curl_setopt($ch, CURLOPT_URL,"http://www.example.com/process.php");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$headers = [

    'X-Apple-Store-Front: 143444,12',

    'X-MicrosoftAjax: Delta=true'
];

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$server_output = curl_exec ($ch);

curl_close ($ch);

print  $server_output ;

best way I know

         window.onbeforeunload = function (e) {
            var e = e || window.event;
            var msg = "Do you really want to leave this page?"

            // For IE and Firefox
            if (e) {
                e.returnValue = msg;
            }

            // For Safari / chrome
            return msg;
         };

They find a solution suboptimally without any guarantee as to the quality of solution found, it is obvious that it makes sense to the development of heuristics only polynomial. The application of these methods is suitable to solve real world problems or large problems so awkward from the computational point of view that for them there is not even an algorithm capable of finding an approximate solution in polynomial time.

Make sure to target x86 on your project in Visual Studio. This should fix your trouble.

This often happens to me when I know there are changes on the remote master, so I try to merge them using git merge master. However, this doesn't merge with the remote master, but with your local master.

So before doing the merge, checkout master, and then git pull there. Then you will be able to merge the new changes into your branch.

In the SVN analogy, Git replaces SVN, while GitHub replaces SourceForge :P

If this project of yours is new, then you can still commit to your local Git, then you can push to GitHub later on. You will need to add your GitHub repo as a 'remote repository' in your Git setup.

They seem to have something for Eclipse users : http://eclipse.github.com/

Otherwise, if you are new to Git : http://git-scm.com/book

A reliable way to address this is

from six.moves import input

six is a module which patches over many of the 2/3 common code base pain points.

You need to use the command pscp and forcing it to pass through sftp protocol. pscp is automatically installed when you install PuttY, a software to connect to a linux server through ssh.

When you have your pscp command here is the command line:

pscp -sftp -pw <yourPassword> "<pathToYourFile(s)>" <username>@<serverIP>:<PathInTheServerFromTheHomeDirectory>

These parameters (-sftp and -pw) are only available with pscp and not scp. You can also add -r if you want to upload everything in a folder in a recursive way.

Tick 'Full Index Enabled' and then 'Rebuild Index' of the central repository in 'Global Repositories' under Window > Show View > Other > Maven > Maven Repositories, and it should work.

The rebuilding may take a long time depending on the speed of your internet connection, but eventually it works.

I would probably do something along the lines of

<div id='search-logo-bar'><input type='text'/></div>

with css

div#search-logo-bar {
    padding-left:10%;
    background:#333 url(logo.png) no-repeat left center;

FindIndex seems to be what you're looking for:

FindIndex(Predicate<T>)

Usage:

list1.FindIndex(x => x==5);

Example:

// given list1 {3, 4, 6, 5, 7, 8}
list1.FindIndex(x => x==5);  // should return 3, as list1[3] == 5;

%lld is the standard C99 way, but that doesn't work on the compiler that I'm using (mingw32-gcc v4.6.0). The way to do it on this compiler is: %I64d

So try this:

if(e%n==0)printf("%15I64d -> %1.16I64d\n",e, 4*pi);

and

scanf("%I64d", &n);

The only way I know of for doing this in a completely portable way is to use the defines in <inttypes.h>.

In your case, it would look like this:

scanf("%"SCNd64"", &n);
//...    
if(e%n==0)printf("%15"PRId64" -> %1.16"PRId64"\n",e, 4*pi);

It really is very ugly... but at least it is portable.

Row Source Type => Value List

Code :

ListbName.ColumnCount=2

ListbName.AddItem "value column1;value column2"

// dict is Dictionary<string, Foo>

Foo[] foos = new Foo[dict.Count];
dict.Values.CopyTo(foos, 0);

// or in C# 3.0:
var foos = dict.Values.ToArray();

Use YAHOO.util.Dom.getElementsByClassName() from here.

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

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

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

below is code for displaying a frame at top-centre of existing window.

Below is the ouput of above code-snippet:

This is what I ended up using inside my .bat file. Windows only of course.

set CURRENT_DIR=%cd%
mkdir ./directoryToExtractTo
cd ./directoryToExtractTo
jar xvf %CURRENT_DIR%\myJar.jar
cd %CURRENT_DIR%

I just found this code snippet simple and functional, try :

public class MainActivity extends ActionBarActivity implements
    ConnectionCallbacks, OnConnectionFailedListener {
...
@Override
public void onConnected(Bundle connectionHint) {
    mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
            mGoogleApiClient);
    if (mLastLocation != null) {
        mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
        mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
    }
}}

here's the link of the tutorial : Getting the Last Known Location

Slightly abbreviated could be...

echo date("Y-m-d H:i:s", strtotime($mysqltime));

You can use the "-r" option to set the sender address:

mailx -r [email protected] -s ...

The exception occurs due to this statement,

called_from.equalsIgnoreCase("add")

It seem that the previous statement

String called_from = getIntent().getStringExtra("called");

returned a null reference.

You can check whether the intent to start this activity contains such a key "called".

Just another hint for those who need to massively convert bytes to binary strings: Use a lookup table instead of using those String operation all the time. This is a lot faster than calling the convert function over and over again

public class ByteConverterUtil {

  private static final String[] LOOKUP_TABLE = IntStream.range(0, Byte.MAX_VALUE - Byte.MIN_VALUE + 1)
                                                        .mapToObj(intValue -> Integer.toBinaryString(intValue + 0x100).substring(1))
                                                        .toArray(String[]::new);

  public static String convertByte(final byte byteValue) {
    return LOOKUP_TABLE[Byte.toUnsignedInt(byteValue)];
  }

  public static void main(String[] args){
    System.out.println(convertByte((byte)0)); //00000000
    System.out.println(convertByte((byte)2)); //00000010
    System.out.println(convertByte((byte)129)); //10000001
    System.out.println(convertByte((byte)255)); //11111111
  }

There is now a headless version of opencv-python which removes the graphical dependencies (like libSM). You can see the normal / headless version on the releases page (and the GitHub issue leading to this); just add -headless when installing, e.g.,

pip install opencv-python-headless
# also contrib, if needed
pip install opencv-contrib-python-headless

I would suggest you to use Super Cache, which is a file cache mechanism which won't use json_encode or serialize. It is simple to use and really fast compared to other PHP Cache mechanism.

https://packagist.org/packages/smart-php/super-cache

Ex:

<?php
require __DIR__.'/vendor/autoload.php';
use SuperCache\SuperCache as sCache;

//Saving cache value with a key
// sCache::cache('<key>')->set('<value>');
sCache::cache('myKey')->set('Key_value');

//Retrieving cache value with a key
echo sCache::cache('myKey')->get();
?>

The simplest command as it can be for k8s pod manifest to run container forever:

apiVersion: v1
kind: Pod
metadata:
  name: ubuntu
spec:
  containers:
  - name: ubuntu
    image: ubuntu:latest
    # Just sleep forever
    command: [ "sleep" ]
    args: [ "infinity" ]

ASMX Web services can only be invoked by HTTP (traditional webservice with .asmx). While WCF Service or a WCF component can be invoked by any protocol (like http, tcp etc.) and any transport type.

Second, ASMX web services are not flexible. However, WCF Services are flexible. If you make a new version of the service then you need to just expose a new end. Therefore, services are agile and which is a very practical approach looking at the current business trends.

We develop WCF as contracts, interface, operations, and data contracts. As the developer we are more focused on the business logic services and need not worry about channel stack. WCF is a unified programming API for any kind of services so we create the service and use configuration information to set up the communication mechanism like HTTP/TCP/MSMQ etc

With @Aikude's variables, I wrote one-liner.

import numpy as np

mylist = [1, 2, 3, 4, 5, 6, 7]
N = 3

mean = [np.mean(mylist[x:x+N]) for x in range(len(mylist)-N+1)]
print(mean)

>>> [2.0, 3.0, 4.0, 5.0, 6.0]

You can use this to get one or more random letter(s)

import random
import string
random.seed(10)
letters = string.ascii_lowercase
rand_letters = random.choices(letters,k=5) # where k is the number of required rand_letters

print(rand_letters)

['o', 'l', 'p', 'f', 'v']

an easy way with out much redundancy.

    Dim fso As Object
    Set fso = CreateObject("Scripting.FileSystemObject")

    Dim Fileout As Object
    Set Fileout = fso.CreateTextFile("C:\your_path\vba.txt", True, True)
    Fileout.Write "your string goes here"
    Fileout.Close

I spent hours on this. I used to not get errors but mails were never sent. Finally I found a solution and I would like to share it.

    To change the name, go to class.phpmailer.php file in your PHPMailer-master folder,
    And change the name here:

require("PHPMailer-master/PHPMailerAutoload.php"); //or select the proper destination for this file if your page is in some   //other folder

                        if(confirm("Your mail has been sent"))

As per James Newton King: If you create the serializer yourself rather than using JavaScriptConvert there is a NullValueHandling property which you can set to ignore.

Here's a sample:

JsonSerializer _jsonWriter = new JsonSerializer {
                                 NullValueHandling = NullValueHandling.Ignore
                             };

Alternatively, as suggested by @amit

JsonConvert.SerializeObject(myObject, 
                            Newtonsoft.Json.Formatting.None, 
                            new JsonSerializerSettings { 
                                NullValueHandling = NullValueHandling.Ignore
                            });

The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. "r-" for a red line, or by explicitely stating the color argument.

import matplotlib.pyplot as plt

plt.plot([1,2,3], [2,3,1], "r-") # red line
plt.plot([1,2,3], [5,5,3], color="blue") # blue line

plt.show()

See also the plot command's documentation.

In case you already have a line with a certain color, you can change that with the lines2D.set_color() method.

line, = plt.plot([1,2,3], [4,5,3], color="blue")
line.set_color("black")

import matplotlib.pyplot as plt
import pandas as pd

df = pd.DataFrame({ "x" : [1,2,3,5], "y" : [3,5,2,6]})
df.plot("x", "y", color="r") #plot red line

plt.show()

If you want to change this color later on, you can do so by

plt.gca().get_lines()[0].set_color("black")

This will get you the first (possibly the only) line of the current active axes.
In case you have more axes in the plot, you could loop through them

for ax in plt.gcf().axes:
    ax.get_lines()[0].set_color("black")

and if you have more lines you can loop over them as well.

It is highly unlikely that adding NameVirtualHost *:443 is the right solution, because there are a limited number of situations in which it is possible to support name-based virtual hosts over SSL. Read this and this for some details (there may be better docs out there; these were just ones I found that discuss the issue in detail).

If you're running a relatively stock Apache configuration, you probably have this somewhere:

<VirtualHost _default_:443>

Your best bet is to either:

• Place your additional SSL configuration into this existing VirtualHost container, or
• Comment out this entire VirtualHost block and create a new one. Don't forget to include all the relevant SSL options.

I know you're interested in a more general answer, but what's good in ASCII is usually good in other encodings. Here is a Python one-liner to determine if standard input is ASCII. (I'm pretty sure this works in Python 2, but I've only tested it on Python 3.)

python -c 'from sys import exit,stdin;exit()if 128>max(c for l in open(stdin.fileno(),"b") for c in l) else exit("Not ASCII")' < myfile.txt

Finally I got a way to to solve this issue by server side as it's more like an issue with AngularJs itself I am using 1.5 Angularjs and I got same issue on reload the page. But after adding below code in my server.js file it is save my day but it's not a proper solution or not a good way .

app.use(function(req, res, next){
  var d = res.status(404);
     if(d){
        res.sendfile('index.html');
     }
});

In my current config I have it defined in application.yaml like that:

logging:
  level:
    ROOT: TRACE

I am using spring-boot:2.2.0.RELEASE. You can define any package which should have the TRACE level like that.

First thing, at the time the question was asked, uintptr_t was not in C++. It's in C99, in <stdint.h>, as an optional type. Many C++03 compilers do provide that file. It's also in C++11, in <cstdint>, where again it is optional, and which refers to C99 for the definition.

In C99, it is defined as "an unsigned integer type with the property that any valid pointer to void can be converted to this type, then converted back to pointer to void, and the result will compare equal to the original pointer".

Take this to mean what it says. It doesn't say anything about size.

uintptr_t might be the same size as a void*. It might be larger. It could conceivably be smaller, although such a C++ implementation approaches perverse. For example on some hypothetical platform where void* is 32 bits, but only 24 bits of virtual address space are used, you could have a 24-bit uintptr_t which satisfies the requirement. I don't know why an implementation would do that, but the standard permits it.

An enum is kind of like a typedef for the int type (kind of).

So the type you've defined there has 12 possible values, however a single variable only ever has one of those values.

Think of it this way, when you define an enum you're basically defining another way to assign an int value.

In the example you've provided, january is another way of saying 0, feb is another way of saying 1, etc until december is another way of saying 11.

Using the same approach of Philip Wallace, we can do like this:

    public Control GetControlByName(Control ParentCntl, string NameToSearch)
    {
        if (ParentCntl.Name == NameToSearch)
            return ParentCntl;

        foreach (Control ChildCntl in ParentCntl.Controls)
        {
            Control ResultCntl = GetControlByName(ChildCntl, NameToSearch);
            if (ResultCntl != null)
                return ResultCntl;
        }
        return null;
    }

Example:

    public void doSomething() 
    {
            TextBox myTextBox = (TextBox) this.GetControlByName(this, "mytextboxname");
            myTextBox.Text = "Hello!";
    }

I hope it help! :)

For all built-in Python objects (like strings, lists, dicts, functions, etc.), if x is y, then x==y is also True.

Not always. NaN is a counterexample. But usually, identity (is) implies equality (==). The converse is not true: Two distinct objects can have the same value.

Also, is it generally considered better to just use '==' by default, even when comparing int or Boolean values?

You use == when comparing values and is when comparing identities.

When comparing ints (or immutable types in general), you pretty much always want the former. There's an optimization that allows small integers to be compared with is, but don't rely on it.

For boolean values, you shouldn't be doing comparisons at all. Instead of:

if x == True:
    # do something

write:

if x:
    # do something

For comparing against None, is None is preferred over == None.

I've always liked to use 'is' because I find it more aesthetically pleasing and pythonic (which is how I fell into this trap...), but I wonder if it's intended to just be reserved for when you care about finding two objects with the same id.

Yes, that's exactly what it's for.

Enhancement of Ben Brandt's answer to compensate even if the string starts with space by applying LTRIM(). Tried to edit his answer but rejected, so I am now posting it here separately.

DECLARE @test NVARCHAR(255)
SET @test = 'First Second'

SELECT SUBSTRING(LTRIM(@test),1,(CHARINDEX(' ',LTRIM(@test) + ' ')-1))

Multi-scale plots are rare to find beyond two axes... Luckily in Matlab it is possible, but you have to fully overlap axes and play with tickmarks so as not to hide info.

Below is a nice working sample. I hope this is what you are looking for (although colors could be much nicer)!

You have a process that is already using that port. netstat -tulpn will enable one to find the process ID of that is using a particular port.

Cast the null literal: (DateTime?)null or (Nullable<DateTime>)null.

You can also use default(DateTime?) or default(Nullable<DateTime>)

And, as other answers have noted, you can also apply the cast to the DateTime value rather than to the null literal.

EDIT (adapted from my comment to Prutswonder's answer):

The point is that the conditional operator does not consider the type of its assignment target, so it will only compile if there is an implicit conversion from the type of its second operand to the type of its third operand, or from the type of its third operand to the type of its second operand.

For example, this won't compile:

bool b = GetSomeBooleanValue();
object o = b ? "Forty-two" : 42;

Casting either the second or third operand to object, however, fixes the problem, because there is an implicit conversion from int to object and also from string to object:

object o = b ? "Forty-two" : (object)42;

or

object o = b ? (object)"Forty-two" : 42;

You are not comparing dates. You are comparing strings. In the world of string comparisons, 09/17/2015 > 01/02/2016 because 09 > 01. You need to either put your date in a comparable string format or compare DateTime objects which are comparable.

<?php
 $date_now = date("Y-m-d"); // this format is string comparable

if ($date_now > '2016-01-02') {
    echo 'greater than';
}else{
    echo 'Less than';
}

Demo

Or

<?php
 $date_now = new DateTime();
 $date2    = new DateTime("01/02/2016");

if ($date_now > $date2) {
    echo 'greater than';
}else{
    echo 'Less than';
}

nodeName is the attribute you are looking for. For example:

var elt = document.getElementById('foo');
console.log(elt.nodeName);

Note that nodeName returns the element name capitalized and without the angle brackets, which means that if you want to check if an element is an <div> element you could do it as follows:

elt.nodeName == "DIV"

While this would not give you the expected results:

elt.nodeName == "<div>"

Since ASP.NET MVC 3, you can use:

@Html.Raw(myString)

If anyone is looking for laravel 5 >

 Auth::id() 

give id of the authorized user

open up console and navigate to bin folder and run

Once it is up and running just copy past your war file in

standalone/deployments folder

Thats probably it for jboss 7.1

Wikipedia's Switch statement entry is pretty big and actually pretty good. Interesting points:

• Switches are not inherently fast. It depends on the language, compiler, and specific use.
• A compiler may optimize switches using jump tables or indexed function pointers.
• The statement was inspired by some interesting math from Stephen Kleene (and others).

For a strange and interesting optimization using a C switch see Duff's Device.

I actually used the answer from How do I run a node.js app as a background service? combined with what dwrz said above. In my case, I was creating a Discord bot that needed to be able to run when I was not around.

With this service in place, I initially got the same error that the initial poster did, which brought me here. I was missing the #!/usr/bin/env node at the top of my executed node.js script.

Since then, no problems, although I intend to see what else can be extended to the service itself.

Html:

<input type="file" name="input-file" id="input-file">

jQuery:

var fileToUpload = $('#input-file').prop('files')[0];

We want to get first element only, because prop('files') returns array.

when click on div alert key

   $(document).delegate(".searchbtn", "click", function() {
        var key=$.trim($('#txtkey').val());
        alert(key);
        });

You could use querySelector() with attribute selector '[attribute="value"]', then affect css rule using .style, as you can see in the example below:

document.querySelector('a[aria-expanded="true"]').style.backgroundColor = "#42DCA3";

<ul><li class="active">_x000D_
  <a href="#3a" class="btn btn-default btn-lg" data-toggle="tab" aria-expanded="true"> <span class="network-name">Google+ with aria expanded true</span></a>_x000D_
  </li>_x000D_
  <li>_x000D_
    <a href="#3a" class="btn btn-default btn-lg" data-toggle="tab" aria-expanded="false"> <span class="network-name">Google+ with aria expanded false</span></a>_x000D_
  </li>_x000D_
</ul>

jQuery solution :

If you want to use a jQuery solution you could simply use css() method :

$('a[aria-expanded="true"]').css('background-color','#42DCA3');

Hope this helps.

Since I could not find this answer nowhere:

ES6 way (Modern Browsers)

el.classList.add("foo", "bar", "baz");

There is 2 ways to do it in angularjs..

1) By directly redirecting to your service call..

<a href="some/path/to/the/file">clickme</a>

2) By submitting hidden form.

$scope.saveAsPDF = function() {
    var form = document.createElement("form");
    form.setAttribute("action", "some/path/to/the/file");
    form.setAttribute("method", "get");
    form.setAttribute("target", "_blank");

    var hiddenEle1 = document.createElement("input");
    hiddenEle1.setAttribute("type", "hidden");
    hiddenEle1.setAttribute("name", "some");
    hiddenEle1.setAttribute("value", value);

    form.append(hiddenEle1 );

    form.submit();

}

use the hidden element when you have to post some element

<button ng-click="saveAsPDF()">Save As PDF</button>

This does the trick safely:

    editText.setText("");
    if (!TextUtils.isEmpty(text)) {
        editText.append(text);
    }

I have build such kind of application using approximatively the same approach except :

• I cache the generated image on the disk and always generate two to three images in advance in a separate thread.
• I don't overlay with a UIImage but instead draw the image in the layer when zooming is 1. Those tiles will be released automatically when memory warnings are issued.

Whenever the user start zooming, I acquire the CGPDFPage and render it using the appropriate CTM. The code in - (void)drawLayer: (CALayer*)layer inContext: (CGContextRef) context is like :

CGAffineTransform currentCTM = CGContextGetCTM(context);    
if (currentCTM.a == 1.0 && baseImage) {
    //Calculate ideal scale
    CGFloat scaleForWidth = baseImage.size.width/self.bounds.size.width;
    CGFloat scaleForHeight = baseImage.size.height/self.bounds.size.height; 
    CGFloat imageScaleFactor = MAX(scaleForWidth, scaleForHeight);

    CGSize imageSize = CGSizeMake(baseImage.size.width/imageScaleFactor, baseImage.size.height/imageScaleFactor);
    CGRect imageRect = CGRectMake((self.bounds.size.width-imageSize.width)/2, (self.bounds.size.height-imageSize.height)/2, imageSize.width, imageSize.height);
    CGContextDrawImage(context, imageRect, [baseImage CGImage]);
} else {
    @synchronized(issue) { 
        CGPDFPageRef pdfPage = CGPDFDocumentGetPage(issue.pdfDoc, pageIndex+1);
        pdfToPageTransform = CGPDFPageGetDrawingTransform(pdfPage, kCGPDFMediaBox, layer.bounds, 0, true);
        CGContextConcatCTM(context, pdfToPageTransform);    
        CGContextDrawPDFPage(context, pdfPage);
    }
}

issue is the object containg the CGPDFDocumentRef. I synchronize the part where I access the pdfDoc property because I release it and recreate it when receiving memoryWarnings. It seems that the CGPDFDocumentRef object do some internal caching that I did not find how to get rid of.

var str = "123, 124, 234,252";
var arr = str.split(",");
for(var i=0;i<arr.length;i++) {
    arr[i] = ++arr[i];
}

for finding out that user is new or old , Get user IP .

create a table for IPs and their visits timestamp .

check IF IP does not exists OR time()-saved_timestamp > 60*60*24 (for 1 day) ,edit the IP's timestamp to time() (means now) and increase your view one .

else , do nothing .

FYI : user IP is stored in $_SERVER['REMOTE_ADDR'] variable

set -x

Prints a trace of simple commands, for commands, case commands, select commands, and arithmetic for commands and their arguments or associated word lists after they are expanded and before they are executed. The value of the PS4 variable is expanded and the resultant value is printed before the command and its expanded arguments.

[source]

Example

set -x
echo `expr 10 + 20 `
+ expr 10 + 20
+ echo 30
30

set +x
echo `expr 10 + 20 `
30

Above example illustrates the usage of set -x. When it is used, above arithmetic expression has been expanded. We could see how a singe line has been evaluated step by step.

• First step expr has been evaluated.
• Second step echo has been evaluated.

To know more about set ? visit this link

when it comes to your shell script,

[ "$DEBUG" == 'true' ] && set -x

Your script might have been printing some additional lines of information when the execution mode selected as DEBUG. Traditionally people used to enable debug mode when a script called with optional argument such as -d

Update : From Angular v1.5, track by $index is now the standard syntax instead of using link as it gave me a ng-repeat dupes error.

I ran into this for a nested ng-repeat and the below worked.

<tbody>
    <tr ng-repeat="row in data track by $index">
    <td ng-repeat="field in headers track by $index">{{row[field.caption] }}</td>
</tr>

With bash you may use read like tis:

#!/usr/bin/env bash

{ IFS= read -rd '' value <config.txt;} 2>/dev/null

printf '%s' "$value"

Notice that:

• The last newline is preserved.

• The stderr is silenced to /dev/null by redirecting the whole commands block, but the return status of the read command is preserved, if one needed to handle read error conditions.

There is no syntax for what you want. Not setting expires causes the cookie to expire at the end of the session. The only option is to pick some arbitrarily large value. Be aware that some browsers have problems with dates past 2038 (when unix epoch time exceeds a 32-bit int).

Yes. In Ruby the not equal to operator is:

!=

You can get a full list of ruby operators here: https://www.tutorialspoint.com/ruby/ruby_operators.htm.

Made it.

from datetime import datetime
dateNow = datetime.now().strftime('%Y%m%d')

Instead of "w" use "a" (append) mode with open function:

with open("games.txt", "a") as text_file:

You should escape it with another backslash \:

print('\\')

There are several ways of doing this, although my personal favorite is:

CFAbsoluteTime timeInSeconds = CFAbsoluteTimeGetCurrent();

You can read more about this method here. You can also create a NSDate object and get time by calling timeIntervalSince1970 which returns the seconds since 1/1/1970:

NSTimeInterval timeInSeconds = [[NSDate date] timeIntervalSince1970];

And in Swift:

let timeInSeconds: TimeInterval = Date().timeIntervalSince1970

If you miss, Microsoft.CSharp.dll this error can occur. Check you project references.

Usually I do this when I expect two objects to be equal:

assertTrue(obj1.equals(obj2));

and:

assertFalse(obj1.equals(obj2));

when they are expected to be unequal. I am aware that this not an answer to your question but it is the closest I can get. It could help others searching for what they can do in JUnit versions before JUnit 4.11.

If you want to submit a POST request

1. You have to set the “request header” section of the Firefox plugin to have a “name” = “Content-Type” and “value” = “application/x-www-form-urlencoded”
2. Now, you are able to submit parameter like “name=mynamehere&title=TA” in the “request body” text area field

I found a website with a "simple" tutorial: http://www.winprog.org/tutorial/start.html

If you want to use Java 8 streams and are allergic to while loops, you could try this:

public static int countPattern(String references, Pattern referencePattern) {
    Matcher matcher = referencePattern.matcher(references);
    return Stream.iterate(0, i -> i + 1)
            .filter(i -> !matcher.find())
            .findFirst()
            .get();
}

Disclaimer: this only works for disjoint matches.

Example:

public static void main(String[] args) throws ParseException {
    Pattern referencePattern = Pattern.compile("PASSENGER:\\d+");
    System.out.println(countPattern("[ \"PASSENGER:1\", \"PASSENGER:2\", \"AIR:1\", \"AIR:2\", \"FOP:2\" ]", referencePattern));
    System.out.println(countPattern("[ \"AIR:1\", \"AIR:2\", \"FOP:2\" ]", referencePattern));
    System.out.println(countPattern("[ \"AIR:1\", \"AIR:2\", \"FOP:2\", \"PASSENGER:1\" ]", referencePattern));
    System.out.println(countPattern("[  ]", referencePattern));
}

This prints out:

2
0
1
0

This is a solution for disjoint matches with streams:

public static int countPattern(String references, Pattern referencePattern) {
    return StreamSupport.stream(Spliterators.spliteratorUnknownSize(
            new Iterator<Integer>() {
                Matcher matcher = referencePattern.matcher(references);
                int from = 0;

                @Override
                public boolean hasNext() {
                    return matcher.find(from);
                }

                @Override
                public Integer next() {
                    from = matcher.start() + 1;
                    return 1;
                }
            },
            Spliterator.IMMUTABLE), false).reduce(0, (a, c) -> a + c);
}

You could compare DOM elements. Remember that jQuery selectors return arrays which will never be equal in the sense of reference equality.

Assuming:

<div id="a" class="a"></div>

this:

$('div.a')[0] == $('div#a')[0]

returns true.

Simple solution:

function betweenDates($cmpDate,$startDate,$endDate){ 
   return (date($cmpDate) > date($startDate)) && (date($cmpDate) < date($endDate));
}

Interesting to note, all sources emphasize that @Column(nullable=false) is used only for DDL generation.

However, even if there is no @NotNull annotation, and hibernate.check_nullability option is set to true, Hibernate will perform validation of entities to be persisted.

It will throw PropertyValueException saying that "not-null property references a null or transient value", if nullable=false attributes do not have values, even if such restrictions are not implemented in the database layer.

More information about hibernate.check_nullability option is available here: http://docs.jboss.org/hibernate/orm/5.0/userguide/html_single/Hibernate_User_Guide.html#configurations-mapping.

Simple Answer: NO

Well, at least a naming convention as such encouraged by Oracle or community, no, however, basically you have to be aware of following the rules and limits for identifiers, such as indicated in MySQL documentation: https://dev.mysql.com/doc/refman/8.0/en/identifiers.html

About the naming convention you follow, I think it is ok, just the number 5 is a little bit unnecesary, I think most visual tools for managing databases offer a option for sorting column names (I use DBeaver, and it have it), so if the purpouse is having a nice visual presentation of your table you can use this option I mention.

By personal experience, I would recommed this:

• Use lower case. This almost ensures interoperability when you migrate your databases from one server to another. Sometimes the lower_case_table_names is not correctly configured and your server start throwing errors just by simply unrecognizing your camelCase or PascalCase standard (case sensitivity problem).
• Short names. Simple and clear. The most easy and fast is identify your table or columns, the better. Trust me, when you make a lot of different queries in a short amount of time is better having all simple to write (and read).
• Avoid prefixes. Unless you are using the same database for tables of different applications, don't use prefixes. This only add more verbosity to your queries. There are situations when this could be useful, for example, when you want to indentify primary keys and foreign keys, that usually table names are used as prefix for id columns.
• Use underscores for separating words. If you still want to use more than one word for naming a table, column, etc., so use underscores for separating_the_words, this helps for legibility (your eyes and your stressed brain are going to thank you).
• Be consistent. Once you have your own standard, follow it. Don´t be the person that create the rules and is the first who breaking them, that is shameful.

And what about the "Plural vs Singular" naming? Well, this is most a situation of personal preferences. In my case I try to use plural names for tables because I think a table as a collection of elements or a package containig elements, so a plural name make sense for me; and singular names for columns because I see columns as attributes that describe singularly to those table elements.

There are different types of shells. The SSH command execution shell is a non-interactive shell, whereas your normal shell is either a login shell or an interactive shell. Description follows, from man bash:

       A  login  shell  is  one whose first character of argument
       zero is a -, or one started with the --login option.

       An interactive shell is  one  started  without  non-option
       arguments  and  without the -c option whose standard input
       and error are both connected to terminals  (as  determined
       by  isatty(3)), or one started with the -i option.  PS1 is
       set and $- includes i if bash is interactive,  allowing  a
       shell script or a startup file to test this state.

       The  following  paragraphs  describe how bash executes its
       startup files.  If any of the files exist  but  cannot  be
       read,  bash reports an error.  Tildes are expanded in file
       names as described below  under  Tilde  Expansion  in  the
       EXPANSION section.

       When  bash is invoked as an interactive login shell, or as
       a non-interactive shell with the --login option, it  first
       reads and executes commands from the file /etc/profile, if
       that file exists.  After reading that file, it  looks  for
       ~/.bash_profile,  ~/.bash_login,  and  ~/.profile, in that
       order, and reads and executes commands from the first  one
       that  exists  and is readable.  The --noprofile option may
       be used when the shell is started to inhibit  this  behav­
       ior.

       When a login shell exits, bash reads and executes commands
       from the file ~/.bash_logout, if it exists.

       When an interactive shell that is not  a  login  shell  is
       started,  bash reads and executes commands from ~/.bashrc,
       if that file exists.  This may be inhibited by  using  the
       --norc  option.   The --rcfile file option will force bash
       to  read  and  execute  commands  from  file  instead   of
       ~/.bashrc.

       When  bash  is  started  non-interactively, to run a shell
       script, for example, it looks for the variable BASH_ENV in
       the  environment,  expands  its value if it appears there,
       and uses the expanded value as the name of a file to  read
       and  execute.   Bash  behaves  as if the following command
       were executed:
              if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
       but the value of the PATH variable is not used  to  search
       for the file name.

I have just faced the same problem. First, you need to install the appropriate Oracle client for your OS. In my case, to install it on Ubuntu x64 I have followed this instructions https://help.ubuntu.com/community/Oracle%20Instant%20Client#Install_RPMs

Then, you need to install cx_Oracle, a Python module to connect to the Oracle client. Again, assuming you are running Ubuntu in a 64bit machine, you should type in a shell:

wget -c http://prdownloads.sourceforge.net/cx-oracle/cx_Oracle-5.0.4-11g-unicode-py27-1.x86_64.rpm
sudo alien -i cx_Oracle-5.0.4-11g-unicode-py27-1.x86_64.rpm

This will work for Oracle 11g if you have installed Python 2.7.x, but you can download a different cx_Oracle version in http://cx-oracle.sourceforge.net/ To check which Python version do you have, type in a terminal:

python -V

I hope it helps

The differences between these values always come down to detailed language-specific rules. What you learn for PHP isn't necessarily true for Python, or Perl, or C, etc. While it is valuable to learn the rules for the language(s) you're working with, relying on them too much is asking for trouble. The trouble comes when the next programmer needs to maintain your code and you've used some construct that takes advantage of some little detail of Null vs. False (for example). Your code should look correct (and conversely, wrong code should look wrong).

You need the following permissions in your manifest file:

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

Then you can use the following in your activity class:

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

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

boolean wifiEnabled = wifiManager.isWifiEnabled()

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

In addition to using Request.Form and Request.QueryString and depending on your specific scenario, it may also be useful to check the Page's IsPostBack property.

if (Page.IsPostBack)
