Hi everyone! This is my first attempt at lemmying. Normally every week some hours before my https://aNONradio.net/ show, I produce a mastodon toot of topics and hyperlinks. This week I will try doing that here on the lemmy (and much earlier - this is the thread) !

IMPORTANT LEMMYS:

lisp community https://lemmy.sdf.org/c/lisp

De facto per gopherhole threads https://lemmy.sdf.org/c/gopher

SHOW TOPICS

Peoples' mathematical packages in Common Lisp?
- @rwxrwxrwx@mathstodon.xyz Juan M. Bello-Rivas
- - https://sr.ht/~jmbr/cl-buchberger/ for example !
- Carlos Ungil's usual-suspects deep learning FFIS
- - https://gitlab.common-lisp.net/users/cungil/projects
My binary hopfield net lisp package
- gopher://tilde.institute/1/~screwtape/binry-hop/
- https://gopher.floodgap.com/gopher/gw.lite?=tilde.institute+70+312f7e7363726577746170652f62696e72792d686f702f
- on Setting Up New ASDF Common Lisp projects
Old computer challenge preparations !
Christy's June 5 questions !
- gopher://gopher.club/1/users/christyotwisty/
- https://gopher.floodgap.com/gopher/gw.lite?=sdf.org+70+302f75736572732f636872697374796f7477697374792f70686c6f672f323032332d4a756e652d466976652d5175657374696f6e732e747874
and I would like to go read lots of other gophers this week.
I didn't sort out music yet. Ancrsprk? Or... You? (Me?)

Seeking suggestions and commentary for this week's show and about using lemmy, which I am new to !

Footnotes: Show art by @prahou@bsd.network !

@rwxrwxrwx@mathstodon.xyz Juan M. Bello-Rivas https://sr.ht/~jmbr/cl-buchberger/ ; Common Lisp Object System based polynomial-ring math

great use of defmethod to handle different useful notions of * / + - , and very powerful LOOP facility.
wonderful to have this common lisp native math package
(implementing buchberger's algorithm to compute a polynomial's Groebner basis, which exposes many of the polynomials properties obviously)
package-wise.. The native package is purely native, and uses the old fashioned packaging idiom (package.lisp) in a source module, but
- the test package uses #:fiasco which extends uiop:define-package and (secretly, I guess) uses/implies the :package-inferred-system idiom for tests.
- So because Juan is also using #:fiasco I think both sides could benefit from asdf's :package-inferred-system, though this would mean lots of uiop:define-package :mix ing of separate files, and the usefulness of :module is subsumed into :package-inferred-system as well.

Carlos Ungil’s usual-suspects deep learning FFIS https://gitlab.common-lisp.net/users/cungil/projects

Carlos Ungil has done exactly the greatest thing.
(Though once again with old fashioned packaging)
Depends on lisp's common cffi package
Since R libraries are fundamentally actually C libraries exposed in the R scripting language, Carlos has simply captured the underlying C libraries and built them into lisp using #:cffi , and done this for a variety of C libraries including both vendor-ish ones like tensorflow, and R's underlying Rmath package.
