The Mini #CommonLISP I have been working on now runs on CP/M with 2416 free cons cells. Enough to load Ken Kahn's tiny PROLOG and run a few simple queries.
The #AgonLight (18MHz eZ80) loads the LISP part of the code (236 lines) in 11 seconds. Simple programs run at acceptable speed, but slightly more complex PROLOG queries take *minutes*. :)
#LISP #CPM #PROLOG #Z80

An afternoon of Lisp programming and now my unit tests have 77 fewer lines. The main changes:

(1) Using multiple-value-list instead of multiple-value-bind before doing asserts on multiple values.

(2) Using flet to define local function composition and reduce boilerplate.

The Medley Interlisp Project: Reviving a Historical Software System https://lobste.rs/s/xontfe #pdf #lisp #retrocomputing
https://interlisp.org/documentation/young-ccece2025.pdf

We are happy to share the preprint and slides of the paper "The Medley Interlisp Project: Reviving a Historical Software System" by Eleanor Young et al.:

https://interlisp.org/documentation/young-ccece2025.pdf

https://interlisp.org/documentation/young-ccece2025-slides.pdf

It tells the first 5 years of the Medley Interlisp Project and discusses what other historical software recovery groups can learn from our experience. The paper was presented at IEEE CCEECE 2025 in Vancouver and accepted for publication.

I wrote a #blog post on why #scheme (more specifically #guile) and #lisp are great for production and real-world #software and why more companies should adopt it, trying to debunk some illusions and fallacies. Enjoy:

#guix is also a great part of why guile is so awesome

My Lisp adventure so far.

I used portacle to install a lisp IDE in Emacs.
https://portacle.github.io/

And I squirreled around a bit with that trying to figure it out.

Then I used this article to set up for web development.

Lisp for the web - 5
https://dev.to/rajasegar/lisp-for-the-web-5-13ca

I had a problem getting the server to load but i checked around a bit and libssl wasn't installed.

I ran
sudo apt install libssl-dev
as described here

https://www.cyberithub.com/how-to-install-libssl-dev-package-on-ubuntu-22-04-lts-jammy/

and I now get the Welcome to Caveman2! screen.

I'm happy to share that my grant proposal to @NGIZero to improve #ecl support in the browser has been accepted!

I released the first alpha of my social media meta-client yesterday. So far only for #SailfishOS but Android's coming too after I've figured out all the Play Store stuff.

This week, DJ @damaru of the Evolution Revolution will talk, including about using emacs as a #writer.

I will share my #eev mode experience, and @eduardoochs should be in #emacsconf on IRC.

I'm going to mention incredible show artist @prahou with reference to gef's last episode.
