FSFE Happy Valentine # Today I got woken up with a friendly hug and roses waiting for me: I do not really care about presents for sort-of-artificial celebration days like valentines day.

The website proposed to e.g. hug a free software developer, to make a gift to a team of free software developers: ...

FOSDEM 2010 - part 1 # Four years ago I was working in Saarbrücken. From there it is a very short ride over to FOSDEM (little more than 300km). So I decided - hey, why not stay there for a weekend. I found a very nice Brussels bed and breakfast hotel called Rovignon - featuring not only comfortable rooms at reasonable prizes but also cats in the house. Back then, I barely knew anyone at the conference. ...

Apache Hadoop at FOSDEM 2010 #

Though the official schedule is not yet online: I will be giving an introductory talk about Apache Hadoop at next year’s FOSDEM (Free and Open Source Developer European Meeting) in Brussles. This will be the 10th birthday of the event - looking forward to a fun event, meeting other free and open source software developers from all over Europe.





If you are a Apache Hadoop developer and would like me to include some particular topic in the talk - please feel free to contact me. If you are an Apache Hadoop user and would like to learn more on the project, please come to the talk and ask questions. If you are an Apache Hadoop Newbie - feel free to join us.

In addition there will be a NoSQL Dev Room at FOSDEM as well. The call for presentations is up already. So if you are doing fun stuff with CouchDB, HBase and friends or are a developer of these projects - submit a talk and join us in early-February in Brussles.
