Learning about type state, phantom, proof, session types in #Rust. You can make it so code literally won't compile unless certain operations happened in a specified order. No runtime checks, no assertions. The type system can catch that. I've wanted this in every language I've ever used.

Photo by Pierre Lavie. Yes this is me. And I threw my Leica. It landed on the bass plate with hardly a scratch. Another Photographer grabbed it along with my phone and I was able to track him later. I was held face down tear gas deployed right in front of me and pepper sprayed directly into the eye.

Decided to build an app for aqui.pr using Claude. The first commit was 3 hrs ago and the app looks legit. I will have to invest some time getting the data sync right but having something I can play with, share and iterate on is awesome.

When I was getting started in programming as a 14-year-old in the '90s, I was steered away from C because my mentor at the time told me that pointers were just too hard.

it would be great if #jj-vcs has a built in bug tracker like fossil-scm that stored the data in the repo. a tui would be enough UI to make it useful. a commercial hosting offering could provide a better experience.
I would love to get paid to work on something like this

the performance argument for nvim is weak. my laptop can handle multiple instances of a "bloated" IDE with dozens of plugins while staying super responsive.

It’s weird that most developers I follow who talk about the subjects I’m interested in software engineering are in game development.
I’ve never been interested in playing or making video games. But I’m starting to come around, my 7yo is really into them, and it’s a great way for us to connect.

Avoid confusion when using jj with long-lived branches (main/dev) by merging PRs instead of squashing them.
Squashing from dev into main creates a new commit in main that doesn't have dev as an ancestor. Now dev and main are in sync but `jj log` looks like they are not. It's a mess 😩
