Stardust@home The Stardust mission Where’s the dust? Stardust@home – 23K volunteers – 43M viewings – 64 tracks found
13
Fold It!
14
Volunteer thinking define goals volunteers ? lab assistants post-docs Herr Professor analyze data literature search perform experiments theorize clean data computers grad students design experiments
15
Middleware jobs middleware people or computers identity accounting queuing assignment validation
16
What’s different? People vary Jobs may not be well-defined aptitude training
17
Bossa Open-source PHP-based middleware for volunteer thinking – http://bossa.berkeley.edu Policies – replication, volunteer assessment, job assignment – Bossa doesn’t provide policies, but makes it easy to implement a wide range of policies

Carl Sagan’s “pale blue dot”... Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves....
