Unlocking Ractors: class instance variables in Ruby (byroot.github.io)
In a previous post about ractors, I explained why I think it’s really unlikely you’d ever be able to run an entire application inside a ractor, but that they could still be situationally very useful to move CPU-bound work out of the main thread, and to unlock some parallel algorithm.

Understanding Memory Management, Part 6: Basic Garbage Collection (educatedguesswork.org)
This is the sixth post in my multipart series on memory management. You will probably want to go back and read Part I, which covers C, parts II and III, which cover C++, and parts IV and V which cover Rust. C++ RAII and Rust do a lot to simplify memory management but still force you to constantly think about how you are using memory (this is even more true with Rust).

Astronomical Calculations for Hard Sci-Fi in Common Lisp (2022) (borretti.me)
In The Epiphany of Gliese 581, a group of explorers search the mortal remains of a dead superintelligence. The expedition begins in Beta Pictoris—today an unremarkable blue star; in the story, a posthuman Dyson swarm civilization of quadrillions—then passes through Gliese 581, and ends where it started.

TIL: timeout in Bash scripts (heitorpb.github.io)
The other day at work we had a Bash script that would set up a web server and wait for it to be up before proceeding to the next things. The script worked fine and we had no issues, until we had an infinite loop.

Claude Code does our releases now (aluxian.com)
Since Anthropic launched Claude Code we've been using it at Molin a lot. It's the best programming agent I've seen so far: it gives concise answers, it can run shell tools as well as edit files, and it's smart enough to make the right call — most of the time. The UX is excellent, too: most times you just press Enter to approve or Esc to give it a new instruction.
