And this will not support 32-bit architectures of #NetBSD. I will fix this.

Tremendous fun last night figuring out how to topologically sort a file (of function definitions for Thun, a dialect of Joy I play with) using just the Unix/POSIX tools. There's already a tsort program that's used in linking, I used awk to convert the definitions into a graph, then xargs and a hash db to sort the original file by the topological order.

smolBSD by @imil could be a nice docker alternative for #littleFedi
I'll perform more tests and will consider to make it an "official deployment method".

I found this is misleading, but I read this protest a lot around, and while I understand it, I think it is a misunderstanding.
Linux never got has goal to make run forever all kind of hardware. It is a misconception because the hardware support is longer and many used it for old machines, but this is coincidental, not a stated goal.

If you need a OS that runs "forever" on everything, that's NetBSD: running everywhere is their goal.

Perhaps what is really needed around is more awareness to alternatives to Linux too, not just for Windows/MacOsX.

A lot of these drivers that are getting removed from Linux, along the 32bit, are niches that can fall into retrocomputing at this point.
If you fall in it, I could suggest you to pick NetBSD, that has the 32 bit support along many things.
You could even run it on an Amiga68k (the CLASSIC hardware!) even if is a low priority port.

@claudiom one more reason to use #NetBSD 🚩

I made a publicly available CalDAV calendar for EuroBSDCon 2026.

Can be used with your favourite... caldav supporting...calendar application. (Everyone has one, right?)

syncthing is finally working.
compiled a new kernel, increased ulimit -n, and started with one connection only, and it's slowly syncing.
no more "too many files open" error.
