Using Eclipse with OpenJDK 6 on Ubuntu
Update: There seems to be a simpler way to do this. Take a look at the second comment. Java 1.6 (also known as Java 6) is now open-source so I installed it on Ubuntu and tried to run Eclipse with it. Unfortunately it said that no compatible java vm was found while searching /usr/lib/j2sdk1.4-sun/bin/java. So…

Profiling PHP with XDebug
Resolving performance problems is hard (even more so when you have to do so with somebody else’s code) and some clear measurements are very welcome. I tried out XDebug some years back when and it didn’t work very well back then, but the latest release seems quite good. Here is how to use its profiler:…

Possible problem with Opera and setTimeout / clearTimeout

Why isn’t my GIN index being used in Postgres after I install the _int contrib package?
While working with some GIN indexes (to speed up the && and <@ / @> operators) I was very surprised to see that after the installation of the intarray (_int) contrib module the query planner stopped using the index. After some poking around it came to me: The contrib module is defining its own operators…

The hard edges of Python
I’ve been playing around with Python (mostly because pefile is written in it) and got very annoyed with the whole white-space as a control structure. In theory it all sounds great: you write beautiful code and it just works. However in practice I find this approach lacking in at least two ways: When moving code…

How can you find out if a site is affected by ThePlanet outage?
If you haven’t heard: The Planet a big, big hosting provider from the USA had some unfortunate incident at one of their hosting facility (involving fires, explosions, etc). Fortunately it seems that no actual computing gear was damaged, however it will be some time until they get back 100% online. In the meantime, if you…
