If I happened to have an old, 32-bit laptop laying around, what #Linux should I put there?
Or maybe #BSD or #Haiku or something else for an old machine, rather than Linux?
@heikkiket While there is a wide range of 32-bit laptops out there and I'm not sure of your use-case, I would probably put Debian on it because it is so rock solid.
@heikkiket debian with lxqt or some other lightweight desktop environment.

@heikkiket i suggest debian, just note that they might be dropping support for i386 in the future: https://www.phoronix.com/news/Debian-Plans-Cease-i386

but debian has a stable release schedule, so the current stable version (bookworm) will be supported until 2026, and then it will have long term support until 2028 so you don't really have to worry about it

Debian Likely Moving Away From i386 In The Near Future

There was recently a mini DebConf in Cambridge where the Debian GNU/Linux release team held a spring and figured out some items moving forward, including the dim future for i386 moving forward.

@heikkiket A debian one, like Bunsenlabs. It's light and speedy, running it on an old Netbook with 1Gb ram and an old 150Gb hdd. It's an oldie Acer Aspire One.

And you could try your hands on multibooting it with FREEBSD and or OpenBSD. I got it multibooting with LMDE (Linuxmint debian), Peppermint, Bunsenlabs and FreeBSD.
