I built a new thing: samth.github.io/rackup/ It's an installer and toolchain manager for @racketlang. It works on Mac and Linux, it lets you install any release including from 1996, and it features all the latest bells and whistles. Also it was built almost 100% using AI.

Ubuntu PPA for Racket 9.1 is now available at launchpad.net/~plt/+archive/… Many thanks to Asumu Takikawa, David Bremner, and Sam Tobin-Hochstadt for all their work.

Now that @racketlang has real parallel threads, I wrote a parallelism benchmark github.com/samth/parbench/ Well, Claude Code wrote it. It's really striking how much more you can do with these tools.
