Random musings of a busy geek

Goodbye Joost, hello Goojet

I have been working at Joost for the last two years as architect of backend systems and tech leader of the backend development team. I started there at a time when the architecture of the system was a blank paperboard. Exciting times, that allowed me to use my creative thinking ...


Cluster computing commoditization

I came across an interesting report on the first Hadoop Summit that happened last week.

Happy New Year!

Happy New Year to you all, known and unknown readers! This year is not yet 2 days old, and there already has been a big change since last year: it is now forbidden to smoke in bars and restaurants in France. Woohoo! No more painfully enduring bad smell or "sorry ...


What compact camera would you recommend?

This is a request to my dear readers. I'm currently looking for a replacement for my Canon Ixus 40 camera. I've never been very happy with its image quality, and lately the lens is doing scary mechanical noise like some missing teeth on gears, and it seems to ...
