Coming up with a paper notation for kids so they can think about programming without filling up short term memory with irrelevancies like the order to put numbers in. https://merveilles.town/@akkartik/112708494215840560

A little app to draw graphs: https://git.sr.ht/~akkartik/snap.love
I've wanted something like this for a long time. Intended for small graphs where laying things out by hand is not too painful, and it's nice that things don't move around every time I make a change, as happens with graphviz (https://graphviz.org). The file format is also amenable to git; no long lines, and adding new nodes or edges doesn't reorder unrelated nodes and edges.
This might be the most mind-bending 20 minutes of my life: https://www.ted.com/talks/donald_hoffman_do_we_see_reality_as_it_is. I wanted more, so I'm watching 1.5 hours at https://www.youtube.com/watch?v=dd6CQCbk2ro
I just figured out how to add tests in my "code as a map" programming environment: https://merveilles.town/@akkartik/109742488349122478

Has anyone heard of stack people vs queue people? I don't know where I got it from, but it's been an enduring part of my self-image for a decade now that I'm a stack person.
When something new pops up, a queue continues what they were doing. A stack switches.
Obviously this is a spectrum, but I find it very easy to rationalize that the new tasks are "quick".
Anyway, being a stack is hard with a new project. Every 2 minutes I discover something broken, and now I have to resist working on it.v

A 4-minute video about my project to replace debuggers with print statements: https://handmade.network/snippet/1561
Weird, I just added hyperlinks to my text editor in 35 lines of code: https://codeberg.org/akkartik/lines-and-links/commit/c81bedca8dddv. Some caveats, but still. This feels like a super power.
For the Handmade Network Wheel Reinvention Jam last week I tried to come up with some tools to help with debug by print: https://handmade.network/p/283/bifold-text
More on my note-taking app, including a command palette and commands for managing a graph of notes: https://merveilles.town/@akkartik/108766067153506592
Still no release. It's still crashing once a day or so. (Never loses data, tho.)
I've been building a note-taking app for the past month, and feeling the pressure to show at least a little bit about it even if it's not released yet: https://archive.org/details/akkartik-pensieve-2022-07-27 (video; 5 mins)
I've been working on a text editor where you can also draw line drawings. Since I put it out I've been getting a trickle of feature requests. Suddenly the need to say no is very real, and I need to make good decisions. I've been using 2 escape hatches:
1. Forks. Somebody proposed an alternative system for drawing polygons that was actually quite self-consistent and had complementary strengths and weaknesses. We don't have to pick one, here's a fork: https://github.com/akkartik/lines-polygon-experiment
2. Add-ons as separate applications. Some people want an exporter to markdown SVG. But most won't. Why complicate the codebase for everyone. Instead: https://merveilles.town/@akkartik/108580451364837131
An editor for plain text where you can also seamlessly insert line drawings: http://akkartik.name/lines.html

Running untrusted apps more flexibly and simply: https://archive.org/details/akkartik-teliva-2021-12-25 (video; 2 minutes)
Programming languages assume you trust all code you run. Browsers assume you trust all network access from websites you visit. With Teliva I'm exploring other approaches in search of a sandboxing model that's both more flexible and easier to understand/trust. (Look for the easter egg involving your favorite protocol.)

There's a Review Jam happening this Advent. Review somebody's project, try to complete a small task, maybe share a video of how it went. Day 2 is my project, Teliva: https://buttondown.email/reviewjam/archive/advent-of-foc-day-2-brutalist-convivial-computing

I just installed Lagrange on a new machine. How can I post as myself on Station from there? I see a way to import a User Certificate but no way to export? Is this even the right approach to pursue?

The Mu shell's error-handling is much improved. Back now to my plan from 3 years ago: a prototyping environment that encourages people to write tests so the prototype can eventually be thrown away and rewritten.

My computer now prints a call stack when it crashes: gemini://akkartik.flounder.online/2021-05-15.gmi
Don't called them signed ints and unsigned ints. Call them ints and addresses. Most of us don't care about the increased range of integers yielded by that final extra bit. But addresses sometimes need to set it. And we never want to think of addresses as negative.
The Mu computer now supports Lisp macros in the prototyping environment: https://merveilles.town/@akkartik/106195814023586904
