I have been working for the past few months on CL-Torch, a Common Lisp equivalent of PyTorch. Like PyTorch, CL-Torch calls LibTorch — the C++ library that does most of the numerics — via FFI.It's nowhere near done, but I need to set it asid…
A couple of weeks ago I released FSet 2.4.0, which brought a CHAMP implementation of bags, filling out the suite of CHAMP types. 🚀 FSet users should have a look at the release page, as it also contained a number of bug fixes and minor chan…

FSet v2.3.0 added transients! These make it faster to populate new collections with data, especially as the collections get large. I shamelessly stole the idea from Clojure. They are currently implemented only for the CHAMP types ch-set, ch…
FSet v2.2.0, which is the version included in the recent Quicklisp release, has a new Quicklisp-loadable system, FSet/Jzon. It extends the Jzon JSON parser/printer to construct FSet collections when reading, and to be able to print them. On…

I have just released FSet 2! You can get it from common-lisp.net or GitHub. A detailed description can be found via those links, but briefly, it makes the CHAMP implementations the default for sets and maps, and makes some minor changes to

Someone asked me what the rationale is for the decision, in my FSet 2.0 release candidate, to have no default default for maps and seqs, so that an out-of-domain lookup will signal an error. I started to write an answer, but after putting t…
I just did some quick-and-dirty benchmarking, using FSet's test suite. It was not designed as a benchmark, but I think it still gives a useful rough indication of how well FSet runs on different platforms. These tests were all run on an Int…
I have just released FSet 1.6.0, which completes the work on CHAMP sets and maps that I started months ago. CHAMP is a hash-based data structure by Michael Steindorfer, that improves a little on Phil Bagwell's widely-used HAMT. (The HAMT is…
For FSet 1.5.1, I have added support for the popular Iterate iteration macro. The issue page has a good explanation. I don't use Iterate myself, or I would no doubt have done this sooner. Also, to implement some of the Iterate functionality…
