Worked on a interesting problem in my project last week, so it was a good opportunity to write about my experience.
It will probably be helpful to me someday, and it might be useful for someone else.

@nolan@toot.cafe @varx@infosec.exchange How could maintainability not matter? On any long term project that does evolve, ease of change is IMO one of the most important factors. That ease depends on code quality/complexity. Unless genAI improves faster then complexity of the code infinitely, you hit the wall as some moment, having a terrible code no-one is willing to touch. I cannot imagine how this can stop being important thing.

Short writing about some metaprogramming in #ruby i did today.

https://jpeterka.cz/2026/05/15/metaprogramming-classmethod/

Do you have experience with similar thing? Is there some simpler solution? Do you use non-OOP approach for such stuff? Curious to hear any feedback !

note to self: when code doesn't seem to work as expected, stop and think what your expectations about relevant parts are and then be sure to validate those

_yes, I just spend two days on problem which was at least partly due to one attribute being always empty, fixed by one `delegate` line_

Any recommendations for domain name registrar?

I imagine:
- EU/non-US based
- support for .cz domain
- trusted
- nonterrible UI
- support for automatic management (for Stalwart for example) would be nice

@pointlessone@status.pointless.one I thought the idea is that it 1) gives time to security researchers 2) when it was released by stealing tokens, it gives the organization time to notice that and rollback. But I might be wrong, and will be glad for more info.
