consumer-grade hardware can run an LLM that hacks the planet. we can stop it, but we don't have much time.

negative build dependencies
A build system needs to know not just which files exist, but which shouldn't exist.

you are in a box
your data is trapped inside the box that is your program. you can only see what the program author exposes.

constrained languages are easier to optimize
exposing raw pointers make the optimizer’s job horribly hard. high level languages can constrain your program, making more optimizations sound.

sorry for the rss screwup
a couple days ago i pushed about 10 empty posts at once to everyone subscribed to my RSS feed. oops. sorry about that.
i've since fixed it, but most RSS readers i've seen will cache the posts indefinitely once they're published. the workaround for my own client was to delete my page and then readd it, which will unfortunately discard all your read/unread state.
the reason this happened is that i added a new kind of "stub" post, and handled that correctly on the main site, but not on the rss feed. you can see the intended layout of the stub posts here if you're interested.

technical debt is different from technical risk
"technical debt" is about updating your understanding of the program over time. "technical risk" is about sacrificing your ability to make changes for speed of development in the short term.
