Update: I've just found http://blog.last.fm/2009/04/06/mapreduce-bash-script

I've read as many search results I could find on this dreaded problem, unfortunatelly, each one seems to focus on a specific function call.
My problem is that I get the same error from multiple functions, which I am guessing are being called back from functions that I use.
To make matters worse, the actual code is within a custom private…

I've tried using the context menu option for resetting the Toolbox to no…
I'm a long-time Eclipse user and I just now decided to try IntelliJ IDEA 9 (free edition) for Scala.
A couple of dumb questions:
How can I tell if a file I've modified has been saved?
How can I tell if I file I've saved has been checked into CVS?
I feel incredibly "exposed" to some sort of imminent danger when I don't see the…
Does anybody know how the dynamic linking and shared library loading works in BusyBox 0.61 ? I can't seem to find how this is done. There's no 'ld' present on the embedded system I'm dealing with, nor is there an LD_LIBRARY_PATH variable set anywhere. My motivation for this is to be able to create a symlink in the /lib directory…
I'm trying to define and use my own foreach function.
This is in the middle of a larger block of code. But the essence of the error I'm getting is this:
test_2.scala:32: error: type mismatch;
found : (A, A) = Unit
required: Function2
$amount.foreach( (k:A,v:A) = {
How is this error conceivably possible?…
Hi there, to start off, I know C++, C#, Python, some Ruby, and basic Javascript. Anyway, my question revolves around how to interact with RESTful API's via Javascript. I haven't been able to find any good examples on various websites, and so I've come here.

I was recently wondering how http://500px.com calculates their "Pulse" rating.
The "Pulse" is a score from 1..100 based on the popularity of the photo.
I think it might use some of the following criteria:
Number of likes
Number of "favorites"
Number of comments
Total views
maybe the time since the photo has been uploaded…

I have an application which writes its log files in a special folder. Now I'd like to add a functionality to delete these logs after a defined period of time automatically. But how long should I keep the log files? What are "good" default values (7 or 180 days)? Or do you prefer other criteria…
My .NET application (VB.NET 3.5 if you really must know) forms do not properly format when rendered at high DPI settings. All of the fixes I've found so far simply explain the cause of the problem as "certain UI elements do not scale properly". I was wondering if anyone had a more meaningful…
Java and .NET seem to have a great number of parallels especially in the web application area. Both languages have many of the same technologies especially in terms of open source libraries (JUnit and NUnit, Hibernate and NHibernate) but there are also plenty of differences and different…
