Teddy in Amsterdam

Teddy in Amsterdam # On his trip from SFO back to Europe teddy spent a few days in Amsterdam. He brought back the following pictures of bikes, cheese and the canals: Going to Amsterdam usually is pretty darn dangerous: I tend to return with some toys added to my collection of puzzles. Somehow I tend to be drawn to the shop called Gamekeeper selling them even when I do not remember the exact address or even just the street name:
Apache Mahout Meetup Amsterdam
February 19, 2011
Apache Mahout Meetup Amsterdam # Last week I was honoured to be invited as one of the two speakers on Apache Mahout at the Mahout meetup in Amsterdam at JTeams offices. After free beer, cola and pizza Frank Scholten gave an overview of Mahout's clustering capabilities. After a brief introduction to Mahout itself he went into a little more detail on how clustering works in general. After that with a selection of Seinfeld scripts he used a fun data set to guide the audience through the process of choosing the right data preparation steps, coming up with good training parameters and finally evaluating clustering quality. ...
FOSDEM - Sunday - smaller bits and pieces

FOSDEM - Sunday - smaller bits and pieces # With WebODF the Office track featured a very interesting project that focusses on providing a means to open ODF documents in your favourite browser: Content and formatting are converted to a form that can easily be dealt with by using a combination of HTML and CSS. Advanced editing is then supported by using JavaScript. With Open Stack the following talk focussed on an open cloud stack project that was started by NASA and Rackspace as both simultanously needed support for an open source, openly designed, developed cloud stack that strives for community inclusion. ...
FOSDEM - HBase at Facebook Messaging
February 17, 2011
FOSDEM - HBase at Facebook Messaging # Nicolas Spiegelberg gave an awesome introduction not only to the architecture that powers Facebook messaging but also to the design decisions behind their use of Apache HBase as a storage backend. Disclaimer: HBase is being used for message storage, for attachements with Haystack a different backend is used. The reasons to go for HBase include its strong consistency model, support for auto failover, load balancing of shards, support for compression, atomic read-modify-write support and the inherent Map/Reduce support. ...
FOSDEM - Django
February 16, 2011
FOSDEM - Django # The languages/ cloud computing track on Sunday started with the good, the bad and the ugly of Django's architecture. Without much ado the speaker started by giving a high level overview of the general package layout of Django - unfortunately not going into too much detail on the architecture itself. What he loves about Django are the model layer abstractions that really are no ORM only - instead both relational and non-relational databases can be supported easily. ...
FOSDEM - Saturday
February 15, 2011
FOSDEM - Saturday # Day one at FOSDEM started with a very interesting and timely keynote by Eben Moglen: Starting with the example of Egypt he voted for de-centralized distributed and thus harder to take over communication systems. In terms of tooling we are already almost there. Most use cases like micro blogging, social networking and real time communications can already be implemented in a distributed, fail safe way. So instead of going for convenience it is time to think about digital independence from very few central providers. ...
