Discussion about permacomputing, small computing, post collapse computing, and related concepts. Considering the clearly related subs on bubble, I guess this sub acts as a place for higher level coordination of ideas in this space.
Notebook conversion - CPU / GPU fan advice sought So I am in the process of converting my old ACER5920G laptop into a "cyberdeck", or rather, something that looks like the immensely cool old MSX2 computers [1]. I have disassembled the laptop, stripped it down entirely. I now have a bare motherboard. I would like make an entirely fanless system if I can help it, or at least I would like to make the CPU (Intel T5500) and GPU cooled with a massive and "decorative" heatsink, and perhaps add a few...

i have this feeling about lowtech (not permacomputing) that gcc is not lowtech. however, tcc is. we feel that c is lowtech, because it has a small syntax and it is possible to write efficient code with it, but we forget that the c we use has lots of corporate investments, lots of language extensions, and the compiler compiles in hours. tcc is lowtech, because it supports standard c without extensions and it is easy to compile it. however, it is not possible to compile linux kernes with tcc....

post text, not audio — publishing audio is convenient, but how to find it on the internet? we even agree on that images should have alt descriptions. otherwise we should rely on ai (which is not lowtech) to find us audio or video files that have the information we search for. p. s. that also relates to 'voice messages' in chats. it is easy to message, but it is not possible later to find the information in the chat log. again, ai may help, but do we want it to help? also, while it is easy...

Gemini over LoRaWAN? — I'm fascinated by the idea of running a smolweb over LoRaWAN. Imagine a decentralized network of FLOSS-hardware devices, solar-powered, each running a gemini capsule and a relay (HAM radio style) to transmit data on to other points on the LoRaWAN mesh network. It's not a fast way to communicate, but smolweb gemini doesn't need to be. If LoRaWAN can reach 56.6kbps, it'd feel like the days of dialup, but... decentralized, solar-powered, and resistant to censorship. Has...

thinking about the idea of fault tolerant networks and protocols. There's a certain amount of overhead to sync-style protocols, and one aspect of this is that updates are tracked. They must be in the protocol, otherwise old versions may propagate. gemini specifically seems to have a gap here, in terms of versioning and proxies.

When it comes to arbitrary, "realtime" composability, the Unix model of files, streams, and processes has yet to be topped. GUIs are vey rarely composable, and also hard to script. It makes me think maybe composability has to be one dimensional, and textual. This idea that a keyboard is fundamental to a computer but a different pointing device doesn't feels slightly off. I wonder if there is an elegant multi dimensional method of composability which simplifies down to simple compute models and...

I managed to get a gemini capsule running on an old phone! it only starts listening on its port when I tell Agate where its content folder is, and goes down when I cancel that command. Not sure why. at least SSH works too, programming on a Blackberry keyboard is not easy. Still a fun way to use old phones.

A potential mental model: we cannot communicate. I need to *imply* a computer program by giving you a file to parse, based on the file contents, but I also need to create the file contents based on what you would also want the file contents to be given that we have the shared goal of independently writing a program to parse the file. Therefore we do not need to share anything and can write the program. Is this possible?

There are a lot of permacomputing adjacent subs but no actual permacomputing sub? I guess it makes sense because centralisation of terminology is a bad thing in a bottom up diverse ideology, but complexity also abounds from the Tower of Babel that bottom up systems create. I'm still trying to understand what I'm looking at and how. But jealous of, say, u/stack just straight up messing with Forth. I don't know how a permacomputing world can hang together.
