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

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.

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

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.)

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?

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.
