<p>Now, I can get the <code>type</code> of the default object, so I know that <code>x</code> should be an int and <code>file</code> should be a str.

909,745 | 909,746 | Selective USB UMS-Mode | <p>is there a way to regulate the UMS-mode? I would like to implement a feature, that lets the user select which files he wants to share with a pc. Say you only want the pc see the picture subfolder, but not all the other folders on your sd. I am not sure if this is possible and most likely I will require root access when possible.</p>
<p>I know this will bring no real security, because you can always remove the sd card and read all the files on it. I thought of this feature mainly because of my crappy car radio. It can read mp3 files from a usb stick. But the many different folders and strange files on a android sd card seems to kill it. Furthermore I think there are a lot of other situation when you would prefer only to show a smaller part of your sd memory to a pc. </p>
<p>Can you imagine any other way to simulate the described behaviour? Can I generate completely new usb modes and implement my own UMS?</p>
<p>Every idea is welcome.</p>

4,537,110 | 4,537,111 | Console application becomes ghost and does not show on task manager processes tab | <p>My program uses MSSQL database and has been working fine. However, after making some changes including converting from VS2008 to VS2010, generating 32bit application. It starts having the following strange problem:
When I try to shutdown the console by clicking the system menu(X button), it does not shutdown, you can move the console around, you can also click on the left hand system menu such as properties, etc, but the program does not show up on the taskmanger's processes tab, therefore, there is no way to shut it down, but to restart box.</p>
<p>Also, while the program is in this ghost mode, I can actually start another instance. That means the ghost application already release most of the resources such as file handle, db etc.</p>
<p>The problem seems to occur after we have some issues with ms-sql server, such as time out exception. I simulate the situation by throwing an exception in the same db function call, but that does create the ghost situation. box is Windows Server Standard without Hyper-V, SP2, 32bit.</p>

829,248 | 829,249 | Seeking on a http progressive download | <p>I am trying to implement the progressive download of audio files in my android project. I am able to progressively play the audio by reading chunks of data and passing on to the media player. So, the media player does play the audio with simultaneous buffering, but the problem lies with seeking.</p>
<p>When I seek to a position where the buffering has not yet completed, then the client requests the server for a range of bytes. Once I receive the range of data, I store it in a file and pass the file descriptor to the mediaplayer, but the mediaplayer is unable to play the audio since the header information is missing.</p>
<p>Is there any better way to do this? Any queue buffering so that the header information is still retained while loading the content at a particular position? Or any other way to handle seeking on a progressive download? </p>
<p>Note that I cannot pass the uri of the audio files to the media player for security reasons.</p>

<p>I want to use ssh to connect to the computer (from a different computer in the same network), but I am not able to access the computer.</p>
<p>Is it possible to portforward, use some kind of transparent proxy or to use DMZ?</p>
<p>My phone is rooted and I have Cyanogenmod installed and I can use iptables.</p>

<p>My setup is the following: I have an android phone connected to a computer through the usb cable tethering internet from the phone, I wanted to ssh into the computer behind the android phone from another computer in the same network as the android phone. This was not possible, because the android phone creates a separate network for the connected computer, effectively shielding it from any incoming signals.</p>
<p>It turned out to be quite simple to fix by just using iptables.</p>

So basically I want to change the css of the hover state of multiple anchor tags, I tried the following code but it didn't work. What's wrong with that?</p>
<pre><code>(".p-container a").each(function () {
$(this).css({'text-shadow':'0 0 0.2px '+ colorArray[i]});
$(this).hover(function() {
$(this).css({'text-shadow':'0 0 2px '+ colorArray[i]});
},function() {
$(this).css({'text-shadow':'0 0 0.2px '+ colorArray[i]});

i++;

<p>The code works without having the hover function, but I want to change the css of the hover state at the same time. Is anybody know how to do that? </p>

It would be very complex to accomplice without Flash?</p>

3,447,954 | 3,447,955 | calling a private method by a return statement java | <p>So I'm new to java and I'm trying to wrap my head around this. So far I'm writing a public method that calls a private method, both of which are written in the same class. When testing the public method, I am able to call the public method against an object, employeeOne, whose parameters are supplied by the user. I'm not exactly sure whats going on with the private method call here though since it appears that I'm calling it on the class (i think) and not the objects with defined attributes. </p>
<p>So here is a private method that I have written inside a class called Employee:</p>
<pre><code>private static double computeGrossPay()
{
if (hoursWorked <= 40)
{
grossPay = (hoursWorked * payRate);
}
else if (hoursWorked >= 40)
{
grossPay = ((40 * payRate) + ((1.5 * payRate) * (hoursWorked - 40)));
}
return grossPay;
}
</code></pre>
<p>I was trying to figure out a way to call this method in another class and obviously since it is a private method I can't call it anywhere outside of the class it is written in. So I wrote a public method that makes a call to the private method</p>
<pre><code>public double grossPayDisplay()
{
return Employee.computeGrossPay();
}
</code></pre>
<p>This is where my question comes into play: So far this code works but I'm not entirely clear on <em>why</em> it works.</p>
<p>Here is how I tested it:</p>
<pre><code>System.out.println(employeeOne.grossPayDisplay());
</code></pre>
<p>employeeOne is an object created from the class Employee whose parameters are supplied by the user, my question is:</p>
<p>How does the compiler go from Employee in Employee.computeGrossPay() to employeeOne? </p>
<p>Or to reiterate how does </p>
<pre><code>return Employee.computeGrossPay()
</code></pre>
<p>actually pass attributes to computeGrossPay()? </p>
