ARM'd and dangerous: kzimmermann takes on the #OldComputerChallenge 2025 with nothing but a Raspberry Pi Model B.

Yes, it's late - but it's done. Sorry for the delay, I was having too much fun learning #NetBSD, I guess :D

Quite impressive that, even under a relatively large workload, #NetBSD's memory usage has never exceeded 240MB in the console environment. Most times, it's around 220MB or so.

And I'm talking a complex workload despite no X11, with tmux, multiple windows with lots of panes each running TUI applications, some as Python apps with a lot of overhead, browser with many tabs open, and even an ebook open to be read.

Yet, I'm not even close to the 512MB limit offered by this Pi1 Model B. This *is* impressive.
