 I often get asked what other systems like Uxn there are out there, so I made a list or relevant small virtual machines and ISAs. Some people think that Pico-8 is its closest neighbor, but it's in fact quite distant: Since version 3, TeX has used an idiosyncratic version numbering system, where updates have been indicated by adding an extra digit, so that the version number asymptotically approaches π. The current version of TeX is 3.141592653; it was last updated in 2021. Thanks @typeswitch for the discovery.

 @neauoire @neauoire @typeswitch and it will reach pi when Donald Kunth dies, when every bug will instantly be considered a feature.  “Yeah but this is the most convoluted Rube-Goldberg way of doing something I’ve ever seen.” We got the new thicker chainplates from the metal fabricator, they look excellent, we've strengthened the deck around where they go through.

Got our new chainplates from the machinist! Helped @rek making the splash page a bit more responsive, check it out!  > He went away from the basement and left this note on his terminal: "I'm going to a commune in Vermont and will deal with no unit of time shorter than a season." Is this

 @neauoire Honestly, not enough software takes into account broken or partially broken input devices. Eg.: my PinePhone's GUI crashed when I was attending Function and I couldn't log in on the terminal because the Linux login prompt doesn't have support for showing my password and the typematic delay on the hardware keyboard was set too low.  Typical officer shit here. West Point has computer labs; the cadet could have just gone and used a working machine. Instead, the cadet made other people do a bunch of work to make up for the consequences of their own carelessness. This is why enlisted people make sure there's always an adult NCO following any West Point graduate around to protect them from themselves...
 @neauoire  “I wish it need not have happened in my time," said Frodo. Splicing one rope into the other, one is going this way, and the other one, the other way. The evolution of the Uxntal programming language writting style over 2 years. @neauoire Old version looks clearer? Also, the new version seems to be missing the audio header, suggesting the old one had sound? Or was that unfinished code that was removed? Everytime Rek questions the measurement I get from our scratched-up barely readable caliper. "IT'S DEAD ON BALLS ACCURATE"  @neauoire Balls, as opposed to feet, is an interesting unit of measurement because it varies based,on water temperature. okay, well I know what I'm going to practice these next couple of weeks, thanks for the tips @fleeky.

@fleeky Just got back, can't do it. Not even close. I'll start with the more basic exercises and build my way there. It's tough as hell @fleeky Starting to get the hang of this, can't do muscle up but I can swing myself equal to the bar and slow down the descent by a bit.

 @neauoire Awesome, 630 bytes! That leaves you so much space to implement the micro-transactions! @neauoire After a whole winter of getting up in the dark to do weight training, I feel it was well worth it as my back pain is gone, I sleep better and feel more overall physically capable. I have a month left of gym membership and plan to make use of it as much as I physically can before its expiration, and our casting off.

@neauoire Do you indulge in indoor rowing? Does wonders with lower-back pain. When properly executed of course.  @neauoire Same! My wife and I have been going to a gym for almost a year now and we feel SO much better. It’s the first exercise regimen that has really stuck for us. Luckily our house isn’t as mobile as yours so we won’t have to cancel anytime soon! 🌻 There's a pretty active #permacomputing lemmy channel on the slrpnk instance. @neauoire I just followed @permacomputing using this Mastodon account of mine. Do you think it'll work?  |

@neauoire The Pico-8 comparison always feel like people conflating Uxn with Varvara. A "more accurate" comparison would be Uxn and the Lua VM that Pico-8 embeds.
However, the LVM isn't intended to be targeted directly and it's opcodes are an internal implementation detail that regularly breaks between versions. On the other hand, Uxn is a VM focused on long term stability, reimplantation, and portability.
(And, the same thing can be extended to Varvara and the Pico-8. Additionally, the Pico-8 is a whole IDE whereas Varvara is just the platform specification.)
I'm just kinda rambling to myself, but I get frustrated cause nobody actually compares the Pico-8 and the LVM to Varvara and Uxn. They just superficially (and often dismissively) state a vague similarity at a first glance.

@neauoire Funnily enough I'm working also on a small virtual machine, but nothing really to show yet. It is based on the idea of mainly storing all your data on 16 stacks though so I am excited to see what direction this will go into or if it'll just crash into the wall
@neauoire I just wanted to talk a little about the Gigatron TTL microcomputer¹: it has a 8-bit CPU made out of a handful of TTL logic chips, with 17 instructions (see picture). This hardware runs a virtual machine that emulates a 34 instructions CPU² to run the real programs :D It manages to do so and produces a VGA signal and a (very noisy) audio output, and it has a gamepad input too!
I got a kit and built it and I still marvel at it!
