<p>I'm a total newbie, but I was writing a little program that worked on strings in C# and I noticed that if I did a few things differently, the code executed significantly faster.</p>

1) I use ticks (e.g. in VB.Net Now.ticks) for measuring the current time. I subtract the starting ticks from the finished ticks value and divide by TimeSpan.TicksPerSecond to get how many seconds it took.
2) I avoid UI operations (like console.writeline).
3) I run the code over a substant... | 14,346 |
<p>Can I write to the end of a 5GB file in Java? This question came up in my office and no one is sure what the answer is.</p>
| <p>This should be possible fairly easily using a <a href="http://java.sun.com/javase/6/docs/api/java/io/RandomAccessFile.html" rel="noreferrer">RandomAccessFile</a>. Something like the following should work:</p>

<p>In theory, you can just open the file in append mode.</p>
<pre><code>OutputStream in = new java.io.FileOutputStream(fileName, true);
</code></pre>
<p>and write till the filesystem fills up.</p>

<p>Im looking to build a thread manager for an application.</p>
<p>I have already started threading and it works entirely fine but I would like to be able to programatically kill them or get information on them.</p>
<p>Does anyone have ideas?</p>
| <p>Just one quick word of warning: don't use <code>Thread.Abort</code> unless you're really shutting down the whole application (or you're calling it from the thread you're aborting, in which case you know what the thread's doing at the time). If you really want to be able to "kill" threads, I'd advise a fairly "soft" ... | <p>Killing threads harshly: not a good idea. You should almost always communicate with a thread (even a simple volatile bit-flag would do), and let the thread commit suicide. Killing it is very risky, and can leave locks on objects etc.</p>
