I keep coming back to these ideas and adiabatic circuits every couple months. My favourite fantasy in this realm is little bots that wait for a problem to solve, then take that problem with them as they crawl into a bath of liquid nitrogen so they can superconduct while they think and consume zero power until they crawl back out with their answer.

I'm proud to have completed my most ambitious tablet weaving project so far. This is an intricately detailed belt with a mix of traditional and self-designed patterns. It's made from 100% cotton that I've pulled and re-spun from worn-out socks, and then dyed with recycled and plant-based materials.

It was about 2 months of work, and 5 sock-ankles-worth of cotton. I'm still working on the write-up for my website, because there's a lot to say about it.

I've been using uxnlin to some good effect, though I have found some confusing results:

STH2r SUB2 STH2 "Redundance"

I'll grant that I could perform the subtraction on the return stack, but I'd have to stash and swap an operand to pull that off, so it'd be the same number of instructions. Am I not seeing something?

I checked the binary diffs and they seemed reasonable, and I ran the test script, but I suspect there isn't test coverage for this change. It's working for ubal, however. I'm guessing we'd want to update the etc/drifblim.rom.txt file if this is accepted. I have the patch pasted here:

_________________________

for absolute position, it seems like mouse is the way to go. I'll need to consider what sort of interactions will be fun to watch as well as what will be fun to edit around. I'm starting to think that the game events might manifest in Orca as bangs and zeros at fixed locations, but the "livecoder" program gradually changes melodies over time until the user starts playing with it. Once the user starts changing things, the livecoder will probably need to stop, though the events can continue.

_________________________

it occurred to me that one way to have the game interact with Orca would be to have it moving the cursor around and appearing to live-code it. That'd be a delightful surprise for the player, I think :moomin_butterfly: I might need to snoop on the zero-page to read the cursor position directly.

2025-11-22T18:12:21Z

Sort of a question for Devine Lu Linvegan (npub1z8r…mrq6) but also for other Orca users/modders: Would it be relatively easy to have Orca embedded in a game (godot engine) and respond to events to create dynamic bgm? For synthesis, I'm looking at Godot-CSound and Godot Synth Engine.

I'm thinking it'd be fun for players to be able to hit the tilde key and see the music being generated live and even mess around with it.

Possible obstacles I foresee include Orca's willingness to toggle between having and not having display/input authority. Also not sure if there'd be a standard way for Orca to accept the events.

2025-11-21T17:28:39Z

I've been continuing work on ubal, and I'm trying to write the code in a way that helps maintain a connection to my mental model, as well as making better use of the conventions of lexing and parsing.

Ideally, I'll end up with a codebase that I (or someone else) can easily modify for use in other cultures with other time formats or numeral conventions. Even if it falls short of that, it's improving readability.

I'm fairly proud of the way I've written the lexing rules: directly in a state-machine specification. It's nested linked lists of blocks of code. You can see them here:
https://git.sr.ht/~fluffysoft/ubal/tree/main/item/src/lib/lexer.tal#L263

I've also written a method to print out all of the state transitions and the character codes on which they happen. You can find that on line 86. It makes use of nesting continuation loops, which I think makes it easier to read.

2025-11-14T22:00:13Z

I'm probably not the first one to do this, but I've made an interesting abstraction within the 'nint' library in ubal. The scan-le-do? and scan-be-do? subroutines scan through a large integer byte by byte (in little-endian or big-endian order) and make it easy for the caller to define operations to take place during that scanning. You can see how it's used in the addition, negation, and multiplication code.

_________________________

I made additional changes and pushed them. I find the tablerule.tal code a lot easier to read now, though it's probably only improved for people with syntax highlighting.

I'm curious if you have any suggestions for the rules/table section. It's a bunch of offsets, and it would be nice to have labels or some similar way of identifying at compile time that an offset is out of range for the given rule.

ah yeah, I discovered that 'enum' style last night on your site and did some cleanup that I must not have pushed yet. Hadn't noticed the $label syntax before.

That "store where it's used" trick seems neat. I'll have to keep an eye out for opportunities to use it.

I really like the latest updates to uxntal, especially the nice new syntax for calling subroutines ( a bit more FORTH-like ). It's fun to use drifblim for compiling, too.

2025-10-30T21:44:51Z

I've gotten back into writing 'ubal' which is attempting to provide some plaintext accounting tools for the uxn varvara ecosystem.

I was inspired by a recent bookkeeping workshop that I gave. I like the plaintext accounting tools that I use, but I believe they could be a LOT smaller. It's also an excuse to imagine other ways things can work.

I'm quite pleased with the way I've implemented the parser. Still a long way to go with feature implementation, but it's feeling like a solid foundation.
