Shout out to Fishbone, who was singing to my white-college-boy ass back in the early 90s about fascism. Not something I ever thought about growing up, and they were trying to get me to see it.

My ride share car smells like air freshener and pot. Reminds me of the summer I lived in a house with six band mates and there was a cinnamon air freshener in the bathroom and the keyboard player came out and said “Mmm cinnamon dump!

I've release a new user interface for mdrepo.org, an open repository of molecular dynamic simulations for proteins, written in Elm (specifically Elm Land). The original version used React/JS and was slow and failed with exceptions. The Elm version should have zero runtime exceptions. #elm-lang

A friend shared a lovely Dijkstra essay. It's short enough to read in a few minutes, and is damning of the current attempt to replace our brains with AI generated writing and vibe coding.

I've become increasingly disappointed my publisher, @oreilly.bsky.social, leaning so heavily into vibe coding. They canceled my Rust course in which I attempt to methodically teach how to learn Rust by writing it oneself. They fired the really good acquisition editors who brought me on board.

A friend would ride with his mom to drop his sister off for piano lessons. Every time, his mom asked him if he'd like to take lessons, too. Every time, he said no. One day, he decided he would say yes the next time his mom asked. She never did, and he never studied the piano.

I don't understand the government taking 10% of Intel profits. Like, isn't that what taxes are supposed to be?

My one food service experience was 27 years ago at a Cracker Barrel in Lewisville, TX, my last semester in college after my folks kicked me off the payroll after a huge fight over my girlfriend.

My current project is continued support and development on this. It's really cool.
mdrepo.org is still live and kicking, and still accepting new contributions.
If you've ever thought to yourself "self, I wish there was a place that I could share all my molecular dynamics (MD) simulations, to support findability and re-use", I have great news!

Trying to reconcile how all positive change had to be incremental, studied in perpetuity & ultimately stalled with ‘how are we gonna pay for that?’ but dismantling everything was done quickly, ham-fistedly & with total disregard for cost of money and lives & no institutional guardrails mattered.

I'm releasing a fun little #Rust tool called "readr" that will print file/STDIN to the screen slow enough to read, kind of like how computers all seem to work in the movies. FWIW, I was exploring async programming with tokio. crates.io/crates/readr

I usually talk about my work in #Rust, but I've also done a lot with #Python. The GitHub repo for my first book, Tiny Python Projects (Manning, 2020), has now hit 2.5K forks! You can find all the videos on YouTube. github.com/kyclark/tiny...
