The stories I know came from Dealers of Lightning and what I remember (correctly I hope) is that the weekly meetings were quite contentious and that he would even encourage haranguing the presenter. Is that true? Did the people there feel it as healthy constructive criticism? I would worry that this would more likely stifle creative thought than encourage it.

If you are computing on a $1000 computer, you are computing in the past.

I know that this was true in the past but it's my contention that hardware has had Moore's Law where software has stagnated, and that the passing of time has meant that now current software doesn't often take full advantage of the hardware available. If you did architect based on where the puck is going (optimized for multi-core, no main memory) current hardware wouldn't slow you down the same way as it did before and sometimes you would even see a performance gain.

By the way, thanks for doing this.
