On Friday in Amsterdam there was a lot of Hadoop on the menu at ApacheCon. I kicked it off at 9am with A Tour of Apache Hadoop, Owen O'Malley followed with Programming with Hadoop’s Map/Reduce, and Allen Wittenauer finished off after lunch with Deploying Grid Services using Apache Hadoop. Find the slides on the Hadoop Presentations page of the wiki. I've also embedded mine below.

I only saw half of Allen's talk as I had to catch my plane, but I was there long enough to see his interesting choice of HDFS users... :)



Also at ApacheCon I enjoyed meeting the Mahout people (Grant, Karl, Isabel and Erik), seeing Cliff Schmidt's keynote, and generally meeting interesting people.
