Brand new and modern CP/M-80 computers!

With USB keyboard, SD card floppies, fixed disk... and all Z80 code (OK 600 MHz ARM host underneath but you wouldn't know unless you poked inside).

https://www.bleeve.me/eZ80/index.html

I have five of them, and 10 more with hardware fix "soon".

Anyone (or two) interested in having one, in exchange for putting a few hours on one and doing a modest review? And report any errors?

These are turn-key boxes (OK, board only for now) and full source and Kicad PCB for download. There's a solid collection of tools and a ton of work in them. I intend these to be solid and reliable daily drivers (sic).

If there's any interest I'll sell assembled and tested boards for cost, probably $60 or so (Teensy 4.1's are $30).

Website downloads are sketchy, complain and I'll fix.

#permacomputing #lowtech

An interesting talk about "#permacomputing" (simplified: using old #hardware as long as possible). Not only is it good for resources and environment, it also can boost creativity and generate unique #artwork exactly *because* of it's limitations.

The **only** title I've found in big tech 📖 reseller regarding #permacomputing https://a.co/d/4YJFfoA Any other pointers are welcome 🌱

this week i discovered the HP Enterprise Microserver - a mighty mite packed to the gills with useful expansion slots

this ten-year-old box has a xeon e3 inside, four 3.5" bays, a PCIe x16 slot, and sd card reader. best of all, it's entirely metal and incredibly well built.

this along with a 2013 mac mini are replacing my wonderful but incredibly hungry mac pro 5,1 server.

at $100, this punches above its weight for value. it uses easily found and cheap parts, and will run forever on that nice delta power supply.

Neato!

I thinking I need to compile a list of technological "sweet spots" past to present, and Palm Pilot is certainly one.

Dark ages are often quite durable.

The Latin West likes to forget that the Roman Empire didn’t fall with Rome, but staggered on like a golem for 1100 years under their fascistic new regime. The emperors were worshipped as semidivine figures anointed by God; you can still see the haloes on their ikons in Orthodox churches.

Under the brutish rulers’ absolute authority, the Christian empire long outlasted the old civic life of res-publica it burnt to the ground. The police state torched Saracen ships with Greek fire as eagerly as they did heretics and “pagan” academies.

No one dared to stop it. No one either in or against the novo ordem did, at least. The people had forgotten how, forgotten how to think beyond the hegemonic order of the Abrahamic world-state. Yet somehow some canny archives survived in monastery back rooms, mouldering on wormy shelves, copied as samizdat by the rare contrarian or cosmopolitan scribe.

Our archives must likewise be built to last for generations, to ensure learning endures such epochs. It goes without saying so far we are very unprepared.

I just saw this one shared on the “Orange Site.” A few of them were written in Common Lisp.

I know Gwen Weinholt has built her Loko Scheme for running on bare metal, I wonder if that should be listed on this site as well?

The digital world we live in is full of excesses. We have come to expect fast speeds, 100% up-time, high resolution and always accessible digital media. The primary version of this website reluctlantly aims to meet those expectations, while highlighting some these issues.

The main version of this site is accessible at all times of the day, but is housed on a self-hosted server, made from recycled, consumer-grade computer parts, on a domestic internet connection, and domestic electricity connection.

The remote website is most precarious, relying on solar power and cellular network, the main version of the website is slightly less precarious.

Building a #smolweb resource list for an upcoming workshop with #permacomputing connections, and for this page:

amazing stuff from:
@sarahgarcin @julienbidoret @joeri_s @adele @lowtechmagazine

Thank you for these beauties!

I seem to remember a resource from @domingoclub but I can't find it anymore, or maybe I dreamt it? Did you run smolweb stuff in BCN?

Am I missing anything else? Thank you thank you thank you thank you!!

The next #PermaComputing Berlin Meet up is this Sunday 18. May:

## DITHERING HEIGHTS ##

Image dithering was once a clever trick for digital imaging on limited hardware in the 1980s. It largely faded from memory as higher power graphic hardware become more ubiquitous. But recently, among those of us interested in a smaller more efficient web, it is having a bit of a renaissance. However, it's not without its critics. This PMC Berlin session will demonstrate and discuss techniques and styles for making images as small as possible. Florian Stolzenhain will bring his ancient Mac and show us some possibilities. We will have a general discussion of limited-palette aesthetics, dirt-style compression and dithering discontents.

once again thinking about the #cyberdeck i wanna make

still looking for a suitable main board, ideally would scavenge one but also need it to be easy enough to mess with since im no pro

Are there any good resources or research on long-lived components? Most of the #permacomputing articles I've seen have been somewhat high-level. For example, I didn't see much discussion of ceramic capacitor aging or the lifetimes of electrolytics. If I wanted to build a device that would run for 200+ years, is there a good source to guide me around the pitfalls?

@radicle @obsidian @torproject

I've been on the lookout for a publishing pathway straight from my #Obsidian vault that is easy, resilient, and open-source.
Now the solution has presented itself:

Simply initialize a #Git repository in a directory of the vault, populate it with stuff to publish and commit.

Then initialize a #Radicle repository in the same directory and watch as your knowledge spreads across the decentralized internet.

You can always view the published repo using the radicle-explorer:

https://app.radicle.xyz/nodes/seed.radicle.garden/rad:z4JGwEBbGhBhqYNMHiQSLt7wQQbTi/tree/technologies/radicle.md

The neat by-product of this method using git is that it makes it stupid easy to collaborate on the knowledge base, fix typos, dead links, etc.
So fundamentally extensible by the public.

Radicle itself then enables this collaboration to be censorship resistant, especially when used with #Tor.
