@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.
