How to check file MIME type with javascript before upload?

How to check file MIME type with javascript before upload?

I have read this and this questions which seems to suggest that the file
MIME type could be checked using javascript on client side. Now, I
understand that the real validation still has to be done on server side. I
want to perform a client side checking to avoid unnecessary wastage of
server resource.
To test whether this can be done on client side, I changed the extension
of a JPEG test file to .png and choose the file for upload. Before sending
the file, I query the file object using a javascript console:
document.getElementsByTagName('input')[0].files[0];
This is what I get on Chrome 28.0:
File {webkitRelativePath: "", lastModifiedDate: Tue Oct 16 2012 10:00:00
GMT+0000 (UTC), name: "test.png", type: "image/png", size: 500055…}
It shows type to be image/png which seems to indicate that the checking is
done based on file extension instead of MIME type. I tried Firefox 22.0
and it gives me the same result. But according to the W3C spec, MIME
Sniffing should be implemented.
Am I right to say that there is no way to check the MIME type with
javascript at the moment? Or am I missing something?

Turning all events .off() and .on() in jQuery

Turning all events .off() and .on() in jQuery

I'm looking at using .off() and .on() to turn event handlers off and on in
jQuery.
I can turn the all attached event handlers off perfectly by using:
$('.eventone').off();
or as a multiple selector:
$('.eventone, .eventtwo, .eventthree').off();
However, I'm not getting all (or even any) event handlers to turn back on.
I'm using this:
$('.eventone, .eventtwo, .eventthree').on();
Is there something I'm doing wrong?
Do I actually have to declare every event that's associated with the class
in order to turn it back on?

Java Scanner delimiter doesn't split the last section

public class Zines {
public static void main(String[] args) throws
FileNotFoundException {
Scanner input = new Scanner(new File("txt.file"));
input.useDelimiter("#");
while(input.hasNext()) {
String title = input.next();
String author = input.next();
String publisher = input.next();
String city = input.next();
String line = input.nextLine();
//int dist = Integer.valueOf(line);
System.out.println(line);
}
}
}
Output is: "#9000 "#8000 "#10000 "#42000 "#29000 "#4000 "#6000
Refrain from the quotations marks! The question here is why does the #'s
still appear after using the delimiter?

How to prevent concurrent streaming

How to prevent concurrent streaming

I have written an app for a radio station, that is working well. If I
click to go back to the desktop and click to activate the application
again, it causes the app to stream again, resulting in 2 streams running
concurrently.
Here is my code;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.setTitle("Standart FM");
startButton = (Button) findViewById(R.id.buttonBasla);
facebookButton = (Button) findViewById(R.id.buttonFacebook);
twitterButton = (Button) findViewById(R.id.buttonTwitter);
Intent myService = new Intent(this, MyMediaPlayerService.class);
pd = new ProgressDialog(MainActivity.this);
mediaPlayer = new MediaPlayer();
if (isOnline()) {
pd.setCancelable(false);
pd.setMessage("Yükleniyor...");
pd.show();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mediaPlayer.setDataSource(path);
mediaPlayer.prepareAsync();
} catch (Exception e) {
e.printStackTrace();
}
mediaPlayer
.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
pd.dismiss();
}
});
} else {
....
}
startButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent myService = new Intent(MainActivity.this,
MyMediaPlayerService.class);
if (mediaPlayer.isPlaying()) {
startButton.setBackgroundResource(R.drawable.andplaybtn);
mediaPlayer.stop();
} else {
startButton.setBackgroundResource(R.drawable.andstopbtn);
mediaPlayer.reset();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mediaPlayer.setDataSource(path);
mediaPlayer.prepareAsync();
pd.setCancelable(false);
pd.setMessage("Yükleniyor...");
pd.show();
} catch (Exception e) {
e.printStackTrace();
}
mediaPlayer
.setOnPreparedListener(new
MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
pd.dismiss();
}
});
}
}
});
}
}

Activity? Please help me.
