Open Source Expo 09 # I spent last Sunday and the following Monday at Open Source Expo Karlsruhe - co-located with web-tech and php-conference organized by the Software-and-Support Verlag. Together with Simon Willnauer I ran the Lucene/Mahout booth at the expo.
So far the conference is still very small (about 400 visitors) compared to free software community events. However the focus was set to be more on professional users, accordingly several projects showed that free software can be used successfully for various business use cases.

Lucene Meetup Oakland # Though pretty late in the evening the room is packed with some 100 people. Most of them solr or pure lucene java users. There are quite a few Lucene committers at the meetup from all over the world. Several even have heard about Mahout - some even used it :)
Some introductiory questions to index sizes and query volumn: 1 Mio documents seem pretty standard for Lucene deployments - several people run 10 Mio neither.

Hadoop Get Together Berlin @ Apache Con US Barcamp # This is my first real day at ApacheCon US 2009. I arrived yesterday afternoon, was kept awake by three Lucene committers until midnight: “Otherwise you will have a very bad jetlag”… Admittedly it did work out: I slept like a baby until about 08:00a.m. the next morning and am not that tired today.
Today Hackthon, Trainings and barcamp Apache happen in parallel.
