Someone on the internet built a web server that runs on solar power and idles at 27MB of RAM. I’ve been thinking about this all week and I can’t stop smiling about it.

The setup is gloriously minimal: a Raspberry Pi Zero W running Alpine Linux in diskless mode — meaning the entire OS runs in RAM — with lighttpd serving static sites and a small Python app handling file sharing. The whole thing is powered by a couple of solar panels feeding into a cheap power station. It handles somewhere between 5 and 15 concurrent users without breaking a sweat, and it costs next to nothing to run. This is the kind of project that makes me remember why I got into tech in the first place.
