Neat GitHub Actions patterns for GitHub Merge Queues

GitHub have enabled their “merge queue” function, which is really exciting! The “it’s not rocket science rule” of software development is a pretty good guiding principle for developing stuff in a team (if CI is fast, more on that later!) - so I’m very glad it gets easier to achieve.

Unfortunately, it’s only “easier” but not “easy”. I was able to use the feature for about a half year while it was in private beta, and while using it my team and I learned a few lessons that make certain things possible (and some others easier).

tsnsrv, or easily accessing services on your tailscale network

Like many people on the internet, I recently saw this great talk by Xe Iaso about things you can do on your Tailscale network with the tsnet package. It got me wondering what more I could do with tailscale myself. Then, three days later, I noticed that my Kobo e-reader had stopped syncing with calibre-web and I knew something about how I accessed my homelab-hosted services would have to change.

Building a golang program with cgo

Recently, I needed to debug a particularly nasty interaction between two programs, one of which was a go tool. To get further in understanding the issue, I had to compile a little test program with cgo, the dreaded (by go programmers) compilation mode that allows go programs to call C code. Unfortunately, it’s a bit difficult to find out what to concretely do in order to build a program with cgo.

Somewhere between 8 and 11 years without boinkmarks

About 8 years ago, I turned off and carted away the server running boinkmarks (aka autobench), the benchmarking and performance tracker for SBCL. It seems like its last entry was around 2009-04-11.

At the time, it had run benchmarks on every revision1 of SBCL since 2004 - I’d been running it for 8 years, as long as I now have not run it.

Time for a retrospective!

basename and dirname in Rust

I recently did some minor file name munging in Rust, and was reminded that one of the hard parts about learning a new language is the differences in vocabulary. In UNIX, there are two command line tools, basename and dirname. They take a pathname as an argument and print a modified pathname to stdout, which is really handy for shell scripts. Several other languages copied that naming convention, and so I was really surprised to find that googling for rust dirname didn’t return anything useful1.

Memorizing passwords with Anki & 1Password

Recently, I started using Anki, a spaced repetition scheduler1, a lot to learn French using the Fluent Forever method, and while there have been setbacks, it’s been a pretty great experience overall. It seems to be super useful for memorizing and retaining all sorts of information! Since I have to memorize all sorts of passwords (phone unlock code, laptop login password, gym locker combination), why not use 1Password to help me retain them?

Why not, indeed!

Editing rustdoc comments in emacs

I’ve been writing a bunch of rust code lately, and it’s been a pretty great experience! The thing I enjoy most about it is that the documentation looks just so extremely good. Which brings me to my major point of frustration with my rust-writing setup: Writing doc comments in emacs’s otherwise excellent rust-mode is a pain. You always have to insert the doc comment character sequence de la ligne, and writing doctest examples was even worse: You write rust code, inside markdown, in rust comments.
