[TUHS] In Memoriam: John Lions

[TUHS] In Memoriam: John Lions

[Dave Horsfall]

We lost Dr. John Lions on this day in 1998; he was one of my Comp Sci 
lecturers (yes, I helped him write The Book, and yes, you'll find my name 
in the back).

He is a hero.  His notes on early Unix made it understandable to me.

Though I have to say that Doug Comer did an equally good job with his XINU
books.  Do you guys know of Doug?  XINU stands for Xinu is not Unix but
he wrote, by himself, an OS and documented it in his books.  I give him
credit for my desire to have code be really simple and self explanatory.

I'd kinda like to invite him to join us, what do you think?

Hopefully this still fits the TUHS charter.  I'd be happy to see
followups move to COFF.

Agreed, modulo (for argument's sake) "equally".  Xinu was the first
book I read on “Unix” internals, and it greatly inspired me.

Go for it!

I first heard of Doug Comer on one of my favourite podcasts History of Networking.

He covers his personal history in the development of TCP/IP in the early days
and I think he does touch on a little bit about Xinu, but I may be misremembering.

Definitely worth listening to: https://rule11.tech/history-of-tcp-ip-with-doug-comer/ .

I would second that. His Xinu book was one of the two that helped
demystify operating systems for me.

A group at Marquette University ported Xinu to run on Linksys/Cisco
home routers. One of the later editions covers it. Pretty sweet.
