Autumn is just around the corner, and when the leaves begin to fall, it will have been four years since the early sketches of a personal computing system which became Uxn. I thought it would be interesting to look back and see what has happened since.
Uxn is such a cool project, I recommend watching Devine’s talk at Strange Loop if you’re interested. I’ve been meaning to try writing some programs for it but haven’t had the chance yet 
This talk was so inspiring for me, thanks for sharing! I first watched it around February and it really motivated me to brush up on my C programming. It’s not at all related to what Devine is doing with Uxn and the tooling around it, lol. I find I have a difficult time with esoteric programming languages and interestingly, the study of C brings me into a headspace not too far from permacomputing, thinking about the trends of contemporary computing and what we can do to improve it.
Yeah C is a good candidate for permacomputing because it does run on everything, though there is a lot of platform-specific behavior making C code not as portable as one might like. Chris Wellons has a lot of posts about writing C in a truly cross-platform way by avoiding the standard library entirely, which I find quite interesting even if it is a little over my head.
