RCL ( https://github.com/ruuda/rcl ) pretty-prints its output by default. Pipe to `rcl e` to pretty-print RCL (which has slightly lighter key-value syntax, good if you only want to inspect it), while `rcl je` produces js

Everything I know about IPv6 comes from this one blog post: https://apenwarr.ca/log/20170810 . It’s from 2017, when IPv6 adoption was 17% according to https://www.google.com/intl/en/ipv6/s

It's a Linux thing too. It bit me in particular when running a script in a container that defaulted to ascii rather than utf-8 locale.

> Python now uses UTF-8 as the default encoding, independent of the system’s environment. Nice, not specifying the encoding is one of the most common issues I need to point out in code reviews.

There is a sweet spot for the bass. Lower is better for deep bass, but too low and it stops being a recognizable note, and consumer speakers can't reproduce it. This effect exists though I'm not sure if it is the cause of the patt

I find them helpful. It happens semi-regularly now that I read something that was upvoted, but after a few sentences I think "hmm, something feels off", and after the first two paragraphs I suspect it's AI slop. Then I go to

Agreed. I got further into this one than usual before I grew suspect, but something felt off.

I wholeheartedly agree, I wrote about this at https://ruudvanasseldonk.com/2025/llm-interactions .

Sure, a different database schema may have helped, but there are going to be bugs either way. In my view a more productive approach is to think about how to limit the blast radius when things inevitably do go wrong.

FYI in an emergency you can `git push` to and `git pull` from any SSH-capable host without the need to use GitHub.

Rent servers from a local provider. It's cheaper, you get more control over the hardware, but most of all, it avoids correlated failures.

I’ve toyed with Cue, but never in a production setting. I like the ideas behind it, it’s very elegant that the same mechanism enables constraining values and reducing boilerplate. It’s somewhat limited compared to Jsonnet, RCL, Dhall, etc.,

GitHub Actions also have function calls, it’s just that they can only occur in very specific places in the program, and to define a function you have to create a Git repository. And don’t forget Ansible playbooks!

From the application point of view, recently I'm converging on this: define data structures for your config. Ensure it can be deserialized from json and toml. (In Rust this is easy to do with Serde; in Python with Pydantic or dataclass
