Smallnet sounds great, if you want us to collaboratively swat up on some topic prior let me know. The spam attack is important but shouldn't eclipse us.

interesting. I had meant to point out that you had recently tooted a look at the life and death of Cyc as a deceased expert system, and in parallel I was reading a book explicitly comparing its KR to CYCL.
At one point, too early in my trajectory to have really understood implications other than a vague connection to DEs, I did at least physically look at every page of Wolfram's monster which is why it lurks in the visual-metaphor-spheres of my brain.

On the topic of catching up on our various readings, I was thinking of you when I was reading the incomplete annex to Sandewall's AICA I finally put on my codeberg, including half a page comparing CYCL to Sandewall's own KRF. https://codeberg.org/tfw/pawn-75/raw/branch/main/aica-1-systems.pdf (page 11)

the idea that occurs to me is that a probabilistic decision tree, even generated to fit some data, is exactly a probabilistic decision tree, even a non-trivial one (halting problem one). Whereas an attempt to universally approximate from sampling the same data has a universe of possibilities, probably exacerbated by having a pre-trained model for example. I'm not sure how to formalize that idea though, and I have many pages on the topic to read.

2025-04-11 08:47:00 GMT

@npub1vlc…mzqq this week you mentioned that gofai are specifically not universal approximators. Is there a particular statement or theorem about the contrasting natures of universal-approximators and old-fashioned AIs?

#emacs #slime #mastoquestion #commonLisp
So, one thing that bugs me about installing slime is the "modify your init file" step. could I add-hook requiring slime-autoloads to the after-startup-hook or something to avoid needing to open my init file at all?
How can I circumscribe adding stuff to the init file in this case?

I guess it's kind of similar to format control strings, isn't it, because they have many similar attributes to regex control strings. Ie
CL-USER> (format t "\"\\\"~%")
"\"
CL-USER> (format t "~s~%" "\\")
"\\"
CL-USER> (format t "~a~a~a~%" #\" #\\ #\")
I guess it's hard to do, isn't it.

Proximally, I was thinking recently it was because #/ was the character dispatch macro in zetalisp in the early 80s. Now it's #\, but I had to add #/ as the "zetalisp character dispatch macro" to run some zetalisp code recently. So there's a reason to choose something else. Also ~/foo:bar/ is a format control in lisp (call the exported bar from foo on the output stream).
To my knowledge, it's encouraged to use the unused bracket characters for this kind of stuff.

did you have opinions viz this whole conversation https://www.dreamsongs.com/Files/PatternsOfSoftware.pdf ?
While reading through the beginning of SICP, I noticed I have a reactionary feeling against the Good Advice shared between a lot of the introductory lisp books. Imagine I have something like
(defun x-value (3-list) (car 3-list)) <=> (setf (symbol-function 'x-value) #'car)
I don't see the poetry of the euphemism x-value for car. So I think lisp objects should all be directly amenable to function-lambda-expression

so it's been a long time since I was playing with plan 9 much.
[Since a lot of plan 9 innovations only make sense if you have never heard of lisp]
With that said acme is basically more completely central to the OS than emacs is to people who like emacs. And presumably you would be using sam style regex inside acme, and all acme's other features. (Basically your developer computer programs always get plumbed through acme = become acme plugins).

Resolution:
The second else refers to the second unless. That's just how it is. :else clauses refer to the earliest unclosed unless (when, if).
There isn't a different way to indent this meaning. Everyone who said the indentation was fine was right.

I always like to write complicated loop logic. Given how intricate loop is as a thing and is to use, you can kind of get intricate and otherwise difficult to attain stuff out of it and so reach intricate places.
I have a question, shouldn't the do's in B imply further indentation for their lines, if you had multiple lines?

Can people say nouns or noun phrases that could be fun drawing prompts for our game?
I've got:
cat
dog
tree
house
star
horsechestnut tree
larch
New Zealand beech
But I'm basically out of ideas

EDIT: I take this back, don't do this:
Ironically, you could pick over the web-available portion of https://letoverlambda.com/ . I think that there are some important examples peppered around that start of the book such as recursive macros. However the book itself points out that the style developed in the book was intended to be an avant garde experiment, so ymmv (alet over plambda .. knowing lisp macros isn't the same at all as wanting to program in this new style).

I've forgotten the author, but their advice was to write the iconic macro once-only yourself. After that, you've got lisp macros.
Edit: ie
(values (1+ x) (1+ x)) would become (let ((<gensym1> (1+ x))) (values <gensym1> <gensym1>))

yeah, tbh seeing the article is an embarrassment. I am confident the article is LLM generated. Extremely repetitive mixture of wrong and not-even-wrong, inanity, buzzwords. I'd probably unpost this.
