linuxusers.in is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
The Mastodon accounts of some projects that preserve, modernize, and reimagine classic operating systems and system software environments:

The worst computer ever made by a leather company. Which there were only two, but it's weird it happened twice (Colorado Leather Company, Tandy Leather).
MOV is the Intel 8080 and x86 Assembly instruction to load in a register the value of another register. Why did they call it move, instead of copy or load, if the value of the source register is not deleted or changed?
Zilog pretty much had to call it load in the Z80 to reduce IP issues but I wonder about the original rationale.
The RetroChallenge announced the winners of the 2024 edition. Great choices, congrats all!

I had a lot of fun entering the challenge, my first one, with a Medley Interlisp project that extended NoteCards to visit websites:
A comprehensive guide to Z80 Assembly that covers not only the instruction set but also programming techniques such as working with data, representing data structure and lookup tables, and more.
Fooling around with my Atari code, I can do pretty fast PM sprites from BASIC, in just a few lines… left/right wrapped fine, but apparently going down traps my clone in blue hell. Oops.

Happy #BringYourAtariToWorkDay to those that celebrate.
Gonna be BASIC-writin' time soon. I'd been meaning to try out FastBasic or ubBasic, but may just stick with TurboBasicXL for period authenticity.

Bill Dyer's memories of the Coherent Unix clone.
At $99.95, in the early 1990s it was the first Unix I could afford and run on my laptop. It taught me a lot. It was a product from an era in which you could pay a one-time fee to buy and own good, packaged software that delivered real value and came with excellent printed documentation.
And here is another one: Monochrome amber CRT on a Hercules Graphics Card.

The pioneering AI program Eurisko by Doug Lenat was the successor of his earlier AM. In this 1981 presentation Lenat explains how Eurisko evolved from the limitations of AM and demonstrates Eurisko written and running in the Interlisp-D environment on a Xerox workstation.
Alright, now that I have migrated to my home grown instance, it's time for an #introduction!
I hack. I've always been drawn to #programming both to solve problems, and to have fun. More recently, I've gotten deep into #electronics design and repair, which dovetails nicely with #RetroComputing. And because I inherited a 3D printer, I've gotten into #3DPrinting, #3DModeling (#Blender), and #CAD (#FreeCAD, #OpenSCAD). And for no reason whatsoever, I've recently gotten into #FreeBSD. I like it.
Occasionally I do some #art things, mostly #procedural or #generative. Or #PixelArt (I'm not good at it). Or #music (also not good at it). I have been known to #dj (I am OK at it, and I love #house and #techno).
I've found the Fediverse fascinating and challenging. Eager to dive deeper. :)
Matheus Lima put together his list of the 7 most influential papers in computer science history, plus 5 more that almost made the cut:
"Before we begin, let me be clear: yes, this is a subjective list. It’s not meant to end the debate — but to start it."
