How is this done? Using the sample for handling tabs, onSavedInstanceState is not called when the tab is switched so where would I save the state? Do I do it at the activity level?

<p>It's really annoying since, after all, the path with a username in it <em>can</em> be resolved unambiguously... I want to write code that can handle any sort of input that a user might give me, but this behavior requires me to call expanduser on every path my code has to deal with. It also means that anywhere I print that path out for the user to see, it will be slightly less legible than what they gave me.</p>
<p>This seems inconsistent with the concept of "duck typing" in which I generalize to mean that I expect python not to whine to me unless there's actually a problem...</p>

3,635,976 | 3,635,977 | Java: Do Thread pools execute tasks simultaneously or sequentially? | <p>My understanding of thread pool is that that when you pass a thread pool a method it picks a thread from its active pool and sends the method off to be executed. My understanding of a thread is that if you put some code in it, it will run through the code without stopping until it is told to sleep or stop.</p>
<p>My question:</p>
<p>When you pass several methods (of roughly equal length to execute) to a thread pool one after another does the thread pool manage sharing between the different threads being executed so that the tasks finish almost simultaneously or does it execute them one after another - for example, task 1 goes into thread 1, thread 1 starts executing it and thread 2 with task 2 in it hasn't had a chance to run until task task 1 has finished because thread 1 was running through the code it has been given without any explicit messages to sleep - so then thread 2 will execute and the tasks will essentially finish one after another.</p>
<p><strong>Basically, do I have to explicitly make sure the code I give to a thread pool has a breaks in it for the threads to run simultaneously? Or do I get this for free when using a thread pool manager?</strong></p>

4,099,466 | 4,099,467 | Cross-references and garbage collection | <p>There is an application with an extensive object graph. This graph mainly consists of a set of subgraphs which are connected to the rest of the graph through the only reference. But internally each such subgraph has some number of cross-references among objects. Once in a while such a sub graph needs to be thrown away. Would it be enough just to set to null the only referece which points to that subgraph to make it eligible for garbage collection?</p>
<p>My concern is that internal cross-references may "protect" the entire subgraph from garbage collection. In other words, is the garbage collector wise enough to figure out that all references in a subgraph do not leave the boundaries of the subgraph and therefore entire subgraph can be purged.</p>

5,010,622 | 5,010,623 | When would one use the BRICK permission? | <p>In Android, there used to be a permission with the name <a href="http://developer.android.com/reference/android/Manifest.permission.html#BRICK">BRICK</a> that could be used to potentially disable the device. Other than hearing it as an urban myth, I do not really know if this permission can really be used to brick a device. </p>
<p>All I can think of are the following reasons:</p>
<ul>
<li>To build a <a href="http://en.wikipedia.org/wiki/LoJack">LoJack</a> kind of an application that can remote disable a phone should it discover that the phone was stolen. </li>
<li>For enterprises to be able to remote-wipe a phone should the phone get lost somewhere.</li>
</ul>
<p>Is there any other sane reason why a third-party app would require to use it? And why was it removed (not sure) from GingerBread?</p>
<p>Also, what does it really do anyways? Reset the phone to its factory settings? </p>

579,759 | 579,760 | string::erase() gives different result in linux/windows | <p>I have a piece of code which reads in a line from a file, then removes the whitespace and tells you the length of the string. In windows it works as I expect it to, however in linux it returns a different result.</p>
<p>Code:</p>
<pre><code> // Find how many characters are in the first line
std::string line;
std::ifstream map ("level1.map");
getline(map,line);
// Remove whitespace from the string to get the useful length of line
for ( unsigned int i = 0, j ; i < line.length( ) ; ++ i )
{
if ( line [i] == ' ' )
{
for ( j = i + 1; j < line.length ( ) ; ++j )
{
if ( line [j] != ' ' )
break ;
}
cout << j;
line = line.erase ( i, (j - i) ) ;
}
}
// Output
cout << line.size() << endl;
</code></pre>
<p>It's essentially just trying to determine how many tile columns there are in the map file, where the map is formatted thusly on each line:</p>
<p>2 2 1 1 1 1 1 1 1 1 1 1 1 1 1 2 2</p>
<p>And so whitespace needs to be removed.</p>
<p>In windows given an initial line length of 160 the end length is 80, however when compiled in linux the initial length is 160, but the end length is 81. The only place the value becomes different appears to be after line = line.erase ( i, (j - i) ) ;</p>
<p>Any ideas why this is happening?</p>

1,628,982 | 1,628,983 | adjusting container position with scrolling | <p>I am attempting to make it so that a set of elements in a div container constantly are present in the a Viewport. I have tried a couple of different approaches but they seem to have repainting issues.</p>
<p><strong>Question:</strong> Any major optimizations to improve performance and remove the visual side effects that stand out? If not, then any alternative approaches?</p>
<p>First approach:</p>
<pre><code> $(viewport).scroll(function ()
{
m_grid.css({ 'marginTop': viewport.scrollTop() + 'px' });
})
</code></pre>
<p>This one causes tiny shaking effects that are obvious to the user.</p>
<p>Second approach:</p>
<ul>
<li>Place a div below and above the contents, shrink and expand them with a little rudimentary math to fill the unused space of the scrollable container.</li>
</ul>
<p>Issue with this approach was that it causes flickering at the edges of the content most likely due to the constant resizing.</p>
<p>Third approach:</p>
<ul>
<li>Place a div that mimics the scrolling behavior directly over where the original scrollbar would be then simple bind scrolling events to it that forwards them to the actual container.</li>
</ul>
<p>Issue with this one is that since the div that actually performs the scrolling is a fake, the mouse wheel wouldn't be usable since it would not have focus when hovering over the elements in the viewport.</p>
<p>Any thoughts on improvements or alternate approaches? It has to be performance-centric.</p>
