I have been interested in permaculture as well as ecologically sustainable computing, and I have finally found a community and concept that ties these two together. I was just browsing Gemini capsules (which you need a compatible web browser for), and I came across this: gemini://sol.cities.yesterweb.org/
Which led me to their http website: https://solflo.neocities.org/
On their about page, they recommend a permacomputing website here: https://compudanzas.net/permacomputing.html
Which contained a link to the Permacomputing wiki (which this post directs to) and a web page from Ville-Matias "Viznut" Heikkilä that I am currently reading: http://viznut.fi/texts-en/permacomputing.html
I hope this is a relevant community to share this. There's not really a permaculture, sustainability, or ~~general computing~~ (just realized there is a technology community, I will crosspost there) community on Lemmygrad that I could find at the moment, but I wanted to share this with my fellow comrades here.
