There is now a new resource for Streams: https://www.ibmdw.net/streamsdev/
The Streamsdev site includes articles, blog entries, videos, and intro labs. You can also get to the download the latest quickstart edition of Streams from there. This way, you can download either the product or a vmware image with it and do the lab at your leisure.
This site is put together by developers for developers. Still, if you are new to InfoSphere Streams, you can find something there for you too. Just go to the getting started section under "Docs".
Since the IBM Information on Demand (IOD) conference starts this weekend, you can also find information on the activities (labs, presentation) on Streams during the conference. You can see the next few acticities on the mainpage or a more complete calendar under events.
This site is evolving. You should go look at it at least once a week to see what's new.
Hopefully many of you are going to the IOD conference next week. Enjoy the conference and learn a lot!
