1. CompSci 296.2 Self-Managing Systems
Shivnath Babu
In this talk my aims are:
- to give an overview of the work that we have been doing at Stanford on adaptive processing in the stream system and what we are doing now
[past and current work]
- facilitate some interesting discussion. Hope the title is provoking enough
I will not be comparing our system with eddies explicitly, although I am doing some work in that respect with DeWitt and one of his students.

2. Reminder Slides and 2-page writeup due by next Tuesday
