I was trying to wait until I had my notes written up, but I'll just give a brief overview of Sys Arch on Friday.
We had our best speaker yet: Daniel McCue of Xerox. He was a very friendly and open person and gave a good lecture that encompassed both hardware and software. It is rare to see such a successful intertwining here at MIT; most applications are addressed as being one or the other.
I'll post my notes as soon as I get them organized.
