I am psyched for sharpsign OldComputerChallenge starting tomorrow! My daily driver is more than a decade old, and to minimise change I'm using that but with 512M and bsd.sp boot constraints. So when the BOOT> prompt appears I BOOT> machine memory =512M BOOT> boot /bsd.mp Also doing 1 hour internet per day, except for for the lispy gopher show. but that's just the beginning! I am using the resurrected MIT-CADR vm[1], using 2048K physical memory, 16127K virtual memory default values. This is the 1981 precommercialisation lispm. (Chinual 4e zetalisp). The lispm is a 1981 graphical three-button-mouse, space cadet keyboard machine. lispm's editor is the zmacs 1981 emacs implementation: GNU emacs' sister. Actually, I have not yet noticed a difference in my usual usage. * What will I be doing? Some goals include 1. Installing a better gopher browser than lynx in my old context 2. Connect to old computer praetor's brutaldon for mastodon 3. Use chaosnet with myself 4. Use chaosnet with someone else * What programming am I doing? If you noticed me collapsing into myself this week from the gopher/lemmy/mastodon, that was concomittant to me getting deep into situation calculus. I had a backlog of computer programs to write, and was searching for a unifying theme. Jose A Alonso, a formal mastodon had linked me a 2022 modernisation review of Green's 1969 use of automatic provers as automatic planners. This is basically a fork of John McCarthy's interest in situation calculus. I was reinventing this idea on a hacker public radio submission a few months ago which nobody understood, least of all myself. Anyway, I got a bit further into developing it as a programming style. My idea is a self-assembling closure on a small search space, working backwards from an exit criteria. Pseudo-functional actions on generalised predicates, clocked for some reason. Okay, we got a bit away from #OldComputerChallenge. But that's what I was working on in the MIT-CADR, and I will be developing and using that. NB. A planner is like being Shakey the Robot.
