Big plus for html/css/js, mostly Pixi 8 or around (I also have a couple threejs). Vanilla JS. I did this by hand before, but having the LLM tweak around the code and styling while I handle more gameplay related things makes this doable (otherwise I just would not have enough free time)

I wrote a (not published to the store, it's kind of just for me) Chrome extension (together with Gemini, pretty early in the days of it) that attaches an expiration date to tabs. Works reasonably well to cure it (except I keep setting many to 31 days… but eventually a month passes)

I would think this is not true

I also wrote a minimal version for me, https://mostlymaths.net/nb/

Only works well on mobile portrait though, I designed it especifically for my phone. Don't use it much though.

I've been writing something similar that keeps evolving, although computable code blocks and markdown have been in there since v1. Runs locally, saves to LocalStorage and is always in a partially broken state because I add more things than those I fix: https://github.com/rberenguel/weave

And a couple recent-ish updates (sadly twitter, because I use it as throw-devlog-there):

Weave: https://github.com/rberenguel/weave

It's hard to explain what it is. Think personal knowledge manager text editor inspired by Acme. The readme and video there are very outdated, I add features faster than I update that (as the only user this is what I get). I post videos of new features on twitter though, as a reminder to myself of where I passed through

Edit and format? I don't remember getting any formatting or editing help from any research journal ever, aside from getting some LaTeX style file.

A web-based "note taking app with weird functionality I want, with a bit of an Acme feel" is the latest one (README severely outdated, but I post screenshots and screen captures of new features in Twitter to leave myself a track record to update it) https://github.com/rberenguel/weave

Somewhat earlier, expiring tabs for Chrome https://github.com/rberenguel/bestBefore

Most of my projects are in one way or another scratching my own itches.

This video constructs a GoL in APL (not one liner). It is quite understandable even if you don’t know APL (I had just started tinkering with APL when I first found it I think): https://m.youtube.com/watch?v=a9xAKttWgP4

In case somebody is curious to see how it might look like.

I should probably brush it up and just upload it to Arxiv. But then I need ok from my advisor, and maybe she’d rather not (since she’d be a coauthor of that..). I’ll try again, thanks for the encouragement.

I did some research on this on the side for my dissertation, but never published it. The fact centers approximate the boundary generalises to almost any point in the plane as a consequence of normality of some sequences, and generalises to most families of complex iteration under very mild conditions. I’ve had a preprint that I never felt like finishing for something like 15 years lying around.

It’s definitely not ergonomic, but very portable. I have it as a backup pointer just in case.

The Wedge Touch Mouse, which has a weird wedge shape and runs out of a single AA battery also has touch sensitive (vertical only IIRC? haven’t used it in a while) scroll as far as I can tell.

I guess I could make the on-screen keyboard work with a text area instead of needing an external one, but I never planned on using that, I find “glass keyboards” annoying to use. It would require some serious changes to the system though, since everything is designed for reading input from a keyboard from “stdin”, so to say.

So far has survived fine, and as long as there are no major changes in the browser (long polling and the JS I use have been available for several years from what I have seen in people who investigated its features). It’s a risk I accepted when I wrote it, worst case the docs are in the Pi, and then PiWrite can be used from any web browser on any modern enough device.

Shilling (or not, it’s open source, who cares). I made this: https://github.com/rberenguel/PiWrite

It is not iA Writer in eink, but I got distant inspiration (I used it a lot back when it was released… a long time ago) and could be closer with effort.

Thanks, I fatfingered the copy paste on my phone :/

I kind of wrote something for this a few years ago: https://github.com/rberenguel/glancer [edited a fat-fingered copy-paste]

The use-case is technical videos (like from conferences) I’m interested, but not enough to invest 20-60 minutes.

Haven’t used it in a few months so the yt-dlp commands may need updating.

Not exactly what you want (I want the same) but I wrote this to scratch that itch: https://github.com/rberenguel/PiWrite
