"Computing size". Incompatible profile file name. Expected format is {timestamp}.profile but was ._124873

I’ve run into this problem twice in the last couple of days while downloading and installing new versions of Eclipse and trying out different packages for PHP editing (PDT and Aptana Studio). First time I googled around I couldn’t find a solution and so had to figure it out myself. Second time I thought that maybe I should make a note of my solution as other people might run into it as well.

The problem shows itself with the following error message:

An internal error occurred during: "Computing size".
Incompatible profile file name. Expected format is {timestamp}.profile but was ._1248736262197.profile.
This happens when trying to install a new plugin through the “Check for updates” or “Install New Software” dialog. The problem is because of the hidden ._* files which are created by OS X inside the Eclipse directory. The solution is pretty easy – open up a terminal and:

cd /path/to/your/eclipse/folder
find . -iname '._*' -exec rm -rf {} \;
WARNING – running commands like this on your computer can cause problems. I have run exactly the command above on my machine with no problem but if you manage to break your computer following the above instructions then I take no responsibility! That said, as long as you correctly cd into the Eclipse directory and type/ copy the command correctly then nothing should go wrong!

Hope that helps someone else who runs into the problem!

GUI for Valgrind

Callgrind uses runtime instrumentation via the Valgrind framework for its cache simulation and call-graph generation. This way, even shared libraries and dynamically opened plugins can be profiled. The data files generated by Callgrind can be loaded into KCachegrind for browsing the performance results. But there is also a command line tool in the package to get ASCII reports from data files without the need to use KCachegrind.

After the Software Wars by Keith Curtis

Given the technology that's already available, we should have cars that drive us around, in absolute safety, while we lounge in the back and sip champagne. This book explains how we can build better software and all get our own high-tech chauffeur.

NEW YORK TIMES BOOK REVIEW:
"Keith Curtis, an 11-year veteran of Microsoft, takes a programmer’s approach in “Software Wars,” attempting to systematically build a case that free software can help pave the way for a 21st-century renaissance in many fields ranging from artificial intelligence (cars that drive themselves) to the human journey into space (space elevators). For Mr. Curtis, free software is all about leveraging our collective intelligence."
