Today Hynek Learned

I’m a big fan of bat as a cat replacement, and I’m an even bigger fan of just as a Make replacement. Sadly, bat doesn’t (and won’t) support Justfile syntax. But you can add it yourself with a little extra effort.

I love my Apple silicon computer, but having to manually switch to Rosetta-enabled shells for my Intel-only projects was a bummer.

If you have a GitHub Actions workflow that sets an output using echo ::set-output key=value, you have started to see an unhelpful deprecation warning. Here’s how to fix it.

Contrary to popular belief, it’s possible to ship portable executables of Python applications without sending your users to Python packaging hell.

GitHub has the concept of co-authors of a commit. You’ve probably seen it in the web UI, when multiple people are listed to have committed something. I want to be gracious with credit where it’s due and I’ve found ways to make it easier.

pip-tools is ready for modern packaging.

If you reuse a @pytest.mark.parametrize many times, it might be time to define a parametrized fixture instead.

Don’t buy it.

How to seamlessly support typing.Protocol on Python versions older and newer than 3.8. At the same time.

Every January 1st, an army of open source developers rushes out to update their copyright attributions in licenses and documentation. Why? Because we’ve always done it that way.

One of my pet peeves are projects without easily accessible changelogs (secondary pet peeve: changelogs without dates). Currently, I’m moving most auxiliary docs to Markdown, because that’s clearly what GitHub and related tooling wants me to. But I don’t want to compromise on my own pet peeve.

The fact that SONOS devices build a transparent Wi-Fi mesh once one of them has wired Internet, is one of the main features of the ecosystem. TIL that at least the Playbar happily shares that mesh with your other devices.

I learn a non-trivial number of things, because there’s Debian drama about them. The fact that the which command is not part of any standard just joined the flock.

In my day job I spend a lot of time dealing with sketchy TLS setups. The error messages provided by OpenSSL tend to be quite opaque – fortunately there’s tools to help you.

On UNIX-like operating systems you can have the Python equivalent of node_modules today, for every Python version, without changing your workflows.

Wanting to update all dependencies in a way that it doesn’t break is somewhat more complicated than expected.

Due to fork() semantics, using rq on macOS can lead to confusing crashes.
