Day 7 ( 006.txt )
#100daystooffload an ode to #lisp #zetalisp , @amszmidt and the #lispm MIT-CADR.

I couldn't reconfigure my brain in the rapidly dwindling remaining time for my #100daystooffload IN ONE HUNDRED DAYS challenge. @82mhz

@pkw @jns @jasmaz @SDF @fstateaudio
definitely sdf commode chat but I will also have ~chat irc open. I should probably be in #lisp #clim #ecl #sbcl ##lispm on liberachat, but it's hard for me to be in three places at once and I seem to often lose my connection to liberachat. If *you* are there you are welcome to remind them the lispy gopher show is happening ( #lisp is a great fountain of technical advice and commentary ). I think @rwxrwxrwx and @jackdaniel are usually over there.

Doug Lenat died. RIP. #cyc #lispm #lispmachines #ai #commonlisp #cycorp

He started the Cyc project, using Lisp Machines as a development environment. The project is roughly since 40 years ongoing. Cyc was the dream of a large-scale knowledge base of common sense knowledge. One that has many ways of reasoning and making inferences. It used SubL a variant of Common Lisp.

Here is an old screen shot...

@amszmidt What does supdup rhyme with? #lispm

@draygon @frescosecco
#lispm or #interlisp #medley

@alchemist
many of us ! In particular I have been awed by @surabax 's recent toot series on symbolics era #lispMachine stuff, who is working on launching #lispIreland https://lisp.ie (WIP) monthly broadcasted talks as well.

@amszmidt for #lispm #MITCADR , @amoroso for #interlisp
as well are centrepoints for me here.

@surabax I might have got the colors reversed again. To annoy Kay a little further, I think the #lispm and #interlisp resurrections were the eventual revolution now after a few decades of worseness, with widespread computers that are powerful enough (too powerful in fact).

By the way, (side topic) on the lispy gopher show tomorrow, is there something in particular I can mention about lisp ireland?

Making the Film: How Stanley and Stella Came Together

https://archive.org/details/how-stanley-and-stella-came-together-sgd-s-news-march-1988

#Symbolics first published the production notes for the movie in March 1988, and now they are availiable on the Internet Archive.

Was this the first instance of a rendering farm?

Stanley and Stella in “BREAKING THE ICE” - Original #Symbolics Tapes Restored & Remastered, 1080p

https://www.youtube.com/watch?v=aYEp26g14Wk

"June 2023 restoration, production, post, and remastering by Tom McMahon, Michael Wahrman, Jim Ryan, and Craig Reynolds."

This is a short animated movie first shown at #SIGGRAPH 87, made with S-Graphics on #LispMachines.

#OldComputerChallenge I "finished" my #zetalisp #lispm planner. To my knowledge the exact same #lisp will function in #CommonLisp as @amszmidt says is often the case. ACL2 admissability though...

The screenshots are of the lispm while playing with the planner.

@trurl
Well no pressure, but if you do and it makes sense to me I will try to straddle it into zmacs, and then maybe forward in time into gnu emacs again. I believe the MIT-CADR vm I am using simulates the c. 1981 #lispm with #zmacs implemented by ZWEI, whose source I have not yet gotten into. On the last lispy gopher show, people in the live COM chat were filling me on ZWEI->EINE, zmacs->Hemlock time progressions. ....->GNU emacs
@amszmidt @nil @icedquinn @sachac

@trurl
I was thinking of asking for that. I am also especially interested in elisp / major mode design at the moment because for old computer challenge I have been using the #lispm whose emacs implementation is #zmacs with #zetalisp major modes (and not gnu or lucient emacs with emacs-lisp).

I wonder if there is or was a near-antecedent to planner-mode major mode for Zmacs ? @amszmidt are you familiar with any TODO style major modes now or previously for zmacs?

#zetalisp #lispm #lisp source and usage (like debugging..)

In which I define LIST records as situation calculus actions over :keyword fluents (for a PLANNER).

Basically an argument to use LISP for mathematics like Sussman, but to culturally inherit Zetalisp's SET-DIFFERENCE and INTERSECTION of LISTs

@amszmidt
Hey should I be calling #'CLOSURE myself? From what I can see, these are the same:
(setq x '5)
(setq closure-1 (let ((x 2)) (lambda () x)))
(setq closure-2 (let ((x 3)) (closure '(x) (lambda () x))))

? #lispm #zetalisp

#OldComputerChallenge
To-do to-day:
1. Screenshot of interlisp, since I was talking about it so people
can see interlisp programs running

2. Write world's simplest planner in #zetalisp #lispm

so many lisp machines

I have had a a shy half-week, but I better get my #OldComputerChallenge on! This is all I'm doing, on my main computer anyway which is amd64 #openbsd and a bit over a decade old:

BOOT> asdfdfsafdf <backspace backspace backspace>
BOOT> machine memory =512M
BOOT> boot /bsd.sp
.. #lispm
$ startx
$ ./m -s
to enter the https://tumbleweed.nu/lm-3/ vm
using 2048K physical memory, 16127K virtual memory

Honestly, this changes nothing for me...
@prahou @thedaemon @supernova @matto @jns @solene @amszmidt

@jackdaniel
thank you for your work on #ecl !

Is anyone using #ecl throughout their #oldcomputerChallenge ? I will use it for common lisp, though I'm also going to try and stay within the #lispm

@rml @civodul @louis @ramin_hal9001
thank all of you as well

@amszmidt Technically, yes 😜, but I like git. No idea why.

But you use Fossil, right?

...

Either way, you're such a crazy #LispM hacker :).

Everyone please invite a friend who likes the #climate , is #old / has an #OldComputer ( #OldComputerChallenge ), or programs in or otherwise has or has had a #lisp (I did).

to the #lispm #gopher #climate at 000UTC Wednesday, in about 22 hours. Original #gopher music. Live chat.
