2022-10-02 A month of conworld

We have returned to Victoria for the winter and reconnected with our little local sailing community, it has been wonderful hearing about everyone's summer adventures. We have a lot of challenging projects to do over the next few months and knowing that we have dependable friends nearby is reassuring.

Like every October, I am dedicating each morning to drawing a different scene from the Neauismetica, and will try to keep it up for as long as I have ideas.

• Sown a sleeve for the Playdate.
• Updated the Playdate implemenation of Uxn to the latest core.
• Added d-pad controls to the Wireworld playground.

2022-09-12 We've got worlds to go to

Once again, finding ourselves having drinks over a scattering of world atlases and passage planning compendiums.

The days are getting shorter, and so is the time that we can spend on the computer, due to our batteries depleting earlier a bit each day. So, I spend my evenings proof-reading the Wiktopher manuscript and reading. I've also taken an unexpected liking of the Playdate, it has been a good companion for the recent rainy days.

• Added monochromatic modes to Orca, CCCC and Catclock.
• Wrote a little program for the Adafruit Playground.
• Finally gotten around to fixing the calendar page.
• Wrote a document reader, called Bouc.

2022-08-30 Hunger for a Way Out

The misantropia that accompanied our return to the noise and smell of the cities, has not yet subsided. We find ourselves surrounded by people, homologous to those who happily mow the lawn at dinner time, who will break the quietude of an anchorage by running a gas generator to watch television as the sun sets.

It's no wonder that birds don't sing here, lest their songs be invariably drowned by the deafening display of the vacationers broadcasting to the fourth horizon over that they are taking it easy.

• Made Drifblim capable of assembling large files, namely Potato.
• Started poking at building a little sequencer again.

2022-08-16 Farewell Desolation

We've left Desolation Sound, and stopped in Texada to reprovision before sailing south. We finally have access to reliable internet access again, but despite my near-endless supply of things to catch up on, none of it sparks any interest in me right now.

Despite my unsettled moods, I was able to built myself a cozy little world to work from, the operating system turned out to be extremly useful in looking through my large collection of pcm, chr and icn files.

2022-08-01 A Potato

We've sailed ourselves into somewhat of an internet deadzone, where my evenings consist of lying in the hammock hung between the jib and the mast, thinking about what sort of an operating system I'd like for myself; what would be both realistic for the Uxn platform, and the limits of my own aptitude for realizing it.

• Built an operating system.

2022-07-16 Slideshow Tech 2000

I haven't had it in me to start new projects these past two weeks, so I've instead revisited projects in need of care; namely Adelie which was until now undocumented, leaving people to guess at how things worked. It has been nice to see some terrific projects made with it, like tower of hanoi, and these gorgeous slides. It took all the restrain in the world not to turn it into another Hypercard.

• Wrote a Thue interpreter, and a tiny desktop calculator.
• Sent artwork to the second issue of Fantomes zine.
• Designed a fresh new bold font for Orca.

2022-07-02 Self Documenting Binaries

The more I try to imagine what resilient software might look like, the more shortcomings I find in Varvara roms, namely, the ones that rely entirely on external documentation. So, I decided to try and begin to tackle this problem by adding a menu navigation manifest to each one, which not only makes the application self-documenting, but also improves accessibility.

• Planted soy at 50°8.549'N 124°56.972'W
• Wrote a macros pre-processor for Drifblim.

2022-06-19 Dwindling Stores

I hate to think that we will, at some point, have to sail south to re-supply, we've both decided that we shall stretch our supplies for as long as we possibly can. We will soon run out of fresh produce, but we have prepared enough preserves to last us for months.

• Wrote our keynote for NIME 2022.
• Transcribed notes over to the Permacomputing Wiki.
• Planted wheat, barley and mustard greens at 50°8.409'N 124°56.842'W

2022-06-03 Uxntal Communication II

We've arrived in Desolation Sound and met up with friends. We spend the long afternoons rowing the dinghy along the shoreline and exploring the thickly forested coast. I went ahead and assigned a glyph to each Uxn opcode, to make an Uxntal Alphabet, it adds a wonderful conlang aspect to the project. I'm hoping to turn this into a little graphical assembler at some point.

2022-06-01 Uxntal Communication I

I couldn't stop thinking about the idea of a Uxntal Sign Language. So, with Rekka's help, I began assigning hand gestures to numbers, operators and modes. I'm also thinking that I might like to assign glyphs so an assembler that does away with English altogether could be envisioned.

• Wrote a linter for Uxntal, and implemented tail-call optimization to uxnasm.
• Planted lentils, mung beans and radishes at 50°8.527'N 124°40.195'W

2022-05-30 Heading North

We are finally making our way north toward Desolation Sound and the Broughton Archipelago. We are spending these late spring days anchored between high mountains, revisiting ideas for projects we conceived of this last winter, but decided to leave for a later time. I've been fascinated by how an entire computing paradigm can emerge from the primitives of combinatory logics, my recent thoughts have been populated by these strange talking birds.

• Implemented an ornithologics playground.

2022-05-14 Slides rules

Aquired a couple of slide rules from a retired teacher, and figured out how to use them. My plan is to gift them to people we meet in our travels. I've spent the better part of the week plotting shapes on paper with the help of the slide rule, while also experimenting with a line-plotting engine, inspired from Turtle Graphics, for creating procedural graphics.

• Made a little spreadsheet program that fits neatly in a 6kb rom.
• Wrote a HTML5 implementation of UxnVM.

2022-04-30 Uxn Specs

I felt frustrated by the development of Uxn this week. It reminded me of the difficult period in Orca's development when it was beginning to be actively used, meanwhile the last few operators were being finalized. Folks would raise hell each time operators were moved around and it made finalizing the spec extremely painful.

2022-04-14 Bedrock Failure

Inspired from the Cuneiform Tablets paper, I considered realizing the paper's point of implementing Smalltalk72 on a UVM, I spent a few days experimenting with the ST72 environment — Only to realize that, like the ChifirVM, it is poorly thought out and fundamentally irreconcilable with my vision of small computing.

• Wrote a plain X11 implementation of Varvara.
• Created an Uxntal REPL, called Varvara's Bicycle.

2022-03-30 FSF

We gave our talk at LibrePlanet 2022, and it went very well. During the Q&A, we talked about living without a fridge, from food preservation to sprouting, and we were delighted to see so many people interested in that stuff. I guess the intersection of computers and gardens is slightly larger than I thought.

• Played a little set for Algorave's 10th anniversary.
• Revamped Orca, Nasu, and Left to support Varvara's new Screen/Auto port.

2022-03-14 Digital Preservation

Took a deep dive into the various experiments in digital preservation(PADI, CAMiLEON, Domesday, etc..), didn't really find anything worthy of note, but it did inspire me to rewrite some of the content on permacomputing. I've also spent the past couple of days improving Noodle, and adding support for tga images.

• Wrote a little single-file Uxntal assembler called Drifblim.

2022-02-30 A Dice Game

Rekka is putting the finishing touches to Wiktopher, and asked me to design a game that the people of Iridi could be playing. I thought a dice game combining the capture mechanism of Go and the randomness of the Domino draw might be a good fit, learn to play Hako.

• Implemented J & Y wiring, in the Uxn port of Orca.
• Wrote a version of minesweeper for Varvara.

2022-02-14

Our upcoming keynote for Libre Planet 2022 has been announced, we've built a little slideshow program for the presentation. I've revamped the Orca documentation and added a reference page, as well as fixing a few bugs in the Uxntal implementation. Toying with wireworld sucked much of my time, again.

Finally, brought back incoming links at the bottom of wiki pages. They had been gone since the migration from C, to Uxntal.

2022-01-30 Tamagochi

Rekka and I completed Yufo, our entry for the Virtual Pet Jam 2022, we also added a Serbian and Polish translation to Thousand Rooms. When I wasn't playing with primes, or reading, I was noodling in wireworld. Ah! Also, Uxn turned one year old.

2022-01-14 Devlog Start

To kick off 2022, I've decided to write 3 documents for the Uxn project, in which I'll save my design notes, the first one is about the virtual machine itself, the second one is about a personal computer and the last one will be a simple operating system. Hopefully, by the end of this year, this project will have have matured into something that is more easily definable.

2021-12-30

Revisited the tga format as a potential transfer format for Varvara applications such as Noodle. I've also been flicking through the massive collection of notes I've accumulated on the topic of paper computing and reflecting on this year that is now ending.

• Wrote a CHIP-8 emulator for Varvara.

2021-12-14

Spent the first few days of December solving the Advent Of Code puzzles in Uxntal, got distracted, and started thinking about image support inside Left. I've also spent time experimenting with the Subleq virtual machine.

• Released the Turye font-editor.
• Released a Cat Clock.

2021-11-30

Was away from Pino to visit family, spent our evenings catching up and watching movies. Received a replacement keyboard for Ayatori, it's good to be working on the Thinkpad again.

• Rewrote the Uxn assembler to use a single pass.
• Released Busy Doing Nothing in paperback.

2021-11-14

Wrote a little brainfuck interpreter in Uxntal during this week's transits. My thoughts have been drifting back to primes and fractions, I've been considering a twist to fractran where fractions with a zero as nominator or denominator might be used as jump operations, but I have yet to implement this.

2021-10-30

Decided to stop doing daily drawings and port Donsol instead. I had it all planned out in my head before starting, I went ahead and completed the port within just a few days. The work was done on a Pinebook Pro, revealing a few issues with Left, so I spent some time optimizing the text-editor so it would run faster.

• Released Donsol, for Varvara.
• Added a reference manual for the Uxntal opcodes.

2021-10-14

Spending the month of October between daily drawings, and various food preservation projects. As I work on a picture, I'll occasionally stop to improve Noodle in some way or correct a bit of friction. The near totality of my computer activities(drawing, composing and programming) are now done from within the Uxn virtual machine. I couldn't be happier.

• Added guides for the line and rect tool, in Noodle.
• Added interface responsiveness, in Dexe.

2021-09-30

Rewrote Dexe to be compatible to the latest changes to Varvara. I'm unsure what to do about Oscean's twtxt and RSS feeds, generating them in Uxntal will be hard, especially the date conversion. Maybe I could build the now page's body from the twtxt feed, but if I did, I would loose the Arvelie timestamps and links. Picked up Moogle again, cleaned up the codebase.

2021-09-14

The grey weather gives us only a few hours of solar power each day, so we alternate between cleaning and doing other things, such as origami. I've been optimizing Orca, trying to make it run faster, inspired by the recent optimizations of Noodle.

• Added d-pad controls, in Orca.

2021-08-30

Currently rewriting Oscean in Uxntal, as an experiment to see how far I can push Uxn, and explore what a wiki from first principles might even look like. A few features have yet to be ported, but the main components are done. We're slowly sailing North toward Vancouver to see friends, we left Saturna for Ladysmith and Silva Bay, Pino has engine problems, again.

2021-08-14

Anchored near Saturna, it has been nice to be working offgrid again. I've started porting paradise in Uxntal, it would be nice to port Oscean at some point too. I'm considering finally stopping daily journaling after 16 years, I think the experiment has run its course. I think a bi-monthly format might be enough for now.
