Finished my constraint solver today. All the constraints are done. The only TODO left is improved testing (probably using cargo mutants) and try to get a sparse algorithm for SVD for telling which vars are underconstrained. Currently we use a dense matrix algo (works, but slow at large systems)

dreamed i won a salad making competition by googling "hitler's favorite salads" finding a listicle of hitler's 20 favorite salads and letting the judges know my opponent had made hitler's 17th favorite salad

Great turnout at Austin Systems! We did lightning talks and had some great demos, including a programmable laser projector and a TUI for burning mixtape CDs at a party (made in @ratatui.rs). Join us Jan 21 for the next one! austinsystems.org

OK, Clair Obscure is pretty fun. I was skeptical because I haven't played a lot of turn-based RPGs... I don't like spending time going through menus. But it's a lot of fun. Combat is still very quick.

I won 50 tacos at my daughter's daycare charity auction. looking for 49 close friends to eat a small nation's worth of calories together.

My workflow for adding constraints to the constraint solver:
- make a property-driven test (TDD)
- build an intuitive equation to measure the error
- translate it into SymPy, generate Rust code for the eqn, and partial derivative for each variable
- Paste that Rust code into the solver
- make a property-driven test (TDD)
- build an intuitive equation to measure the error
- translate it into SymPy, generate Rust code for the eqn, and partial derivative for each variable
- Paste that Rust code into the solver

Yikes, I just found a nasty bug in SymPy. Spot the difference between these representations of the equation! github.com/sympy/sympy/...

The future of coding is KCL. If you aren't learning KCL to build parametric CAD models for your cars, space rockets, or even just simple parts around your house, you're going to be left behind. In a decade, there won't be any coding jobs left outside of KCL.

Tomorrow is austinsystems.org big December meetup! We're doing lightning talks (strict 10 minute limit) and we'll have pizza and beer. Hope to see y'all there!

It's insane that people do their Year In Review from December. You're just giving up on 8% of the year. Sometimes you discover your favorite album on December 2nd.

I really liked the new Knives Out but I think the de-aging CGI of Tim Curry was really tacky and unnecessary.
