Excited as I was to see this history of Unix code in a single repository:
it continues the long-standing tradition of ignoring all the work done at Bell Labs after v7. I consider v8 v9 v10 to be worth of attention, even influential, but to hear this list talk about it - or discussions just about anywhere else - you'd think they never existed. There are exceptions, but this site does reinforce the broadly known version of the story.
It's doubly ironic for me because people often mistakenly credit me for working on Unix, but I landed at the Labs after v7 was long dispatched. At the Labs, I first worked on what became v8.
I suppose it's because the history flowed as this site shows, with BSD being the driving force for a number of reasons, but it feels to me that a large piece of Unix history has been sidelined.
I know it's a whiny lament, but those neglected systems had interesting advances.
