There may be others.
@humanetech @df5t0rw we got GtS running on a Raspberry Pi Zero W (so, <512mb of ram and 1 cpu). It runs, but it struggles with encoding blurhashes for images, so we still need to do some performance enhancements there to make sure requests don't time out. The issue is CPU rather than ram though -- GtS itself only uses between ~20mb => ~100mb of ram in testing so far (for a single user instance). But the poor little CPU on the Pi Zero struggles :D
@michal yep I was a fan of hubzilla... I even built some plugins for it for my instance a while ago. But it's PHP. I worked with PHP for many years and now for my "hobby projects" I just don't want to do any PHP stuff ^^'. So... Yeah I got a pretty stupid raison not to try hubzilla ;)
@michal but it's the purity of it. I like C (and not c++) for this: it does exactly what you ask of it; nothing more.
I have re-did many low level function only to understand them for fun and it made me progress a lot in every other language.
Php is "close to c" in term of performance compared to many other languages and still is lightyears from C speed. Same for "go".
So... A C activityPub not dependant of a big "helper stack" would nice to implement ^^'
