i used to joke that the solution to the housing crisis is to make home prices lower but keep home values high, but slowly realized that's what a lot of the financial engineering is actually trying to do.

i'm starting to get effect.website pilled. started to add some to the @val.town codebase. loving that it's one big dependency with a common style & maintainers. doesn't seem that much more cryptic than neverthrow in practice. discovered one bug so far, in datetime parsing, but robust otherwise.

I'm working on a new kind of computer. It's called the Radiant.
I've been dissatisfied with the state of personal computing for many years now, so it's time I did something about it.
If you think computers could be so much better than what they are, this is for you.

this has to be coupled with the things that *don’t* count as a scandal: an array of harassment allegations, covering up Covid deaths, staying in a race after losing the primary, etc.
