Amen to that. I think we all lived, you Bell Labs people especially, in a simpler time. We were trying to fit into 64K, split I/D 128K, my Z80 was 64K but some extra for graphics, then the VAX came and we were trying for 1MB, Suns with 4MB. So small mattered a lot and that meant the Unix philosophy of do one thing and do it well worked quite nicely. What that also meant, to people coming on a little bit after, was that it was relatively easy to modify stuff, the stuff was not that complex. Even I had an easy time, my prime was back at Sun when SunOS was a uniprocessor OS. That is dramatically simpler than a fully threaded SMP OS that has support for TCP offloading, NUMA, etc, etc. I really don't know how systems people do it these days, it is a much more complex world. So I'm with Norm, it was fun back in the day to be able to come in and have a big impact. I too wish that it was as easy for young people to come in and have that impact. I've done that and it was awesome, these days, I have no idea how I'd make a difference. --lm
