Last week I was in Amsterdam on Hadoop Summit. I really enjoyed most of the presentations. I tried to follow rather the technical track, but even those more abstract sessions were often inspiring, so after two days I arrived at home very motivated. It would be great to visit Amsterdam next year.
Just to keep this entry a bit informative I will include one off-topic idea that was mentioned on the summit.
Project Openpaths was mentioned in one of the presentations. It was started by the New York Times and the main idea is to keep track of people movements. Thanks to the app installed on your smarthone you will have log of your positions available to download from the openpaths.cc site. Mayby I come back later with some visualisation idea, for now have just started collecting data.
