The #Lean homepage uses “L∃∀N” as the logo but says, “Lean is an open-source programming language and proof assistant that enables correct, maintainable, and formally verified code”. #formal-methods
#Lean online playground storing the code in an URL fragment. This is supposed to be a solver for a couple of linear inequalities. But it takes forever to load and then I can’t figure out how to actually run anything.

Yaron Minsky at #Jane-Street, the guy Will has been talking to, wants to adopt #formal-methods now, though previously they haven’t because of the costs. “And those costs are really high! seL4 is a great example of this. It’s a formally verified microkernel, and a profound achievement. But, boy was it expensive to do! It took 25 person-years of effort to verify 8,700 lines of C, and each line of code required something like 23 lines of proof and a half a person-day to verify.” But now they have “agentic coding”, meaning #AI.

new #Primitive-Technology video, building a new hut with previously fired clay bricks and mud mortar with a little bit of wood ash added to grout it. He makes a plumb bob and shows why he should have had it before. Also he shows an unsuccessful #firestarting attempt before the successful one, saying that this is common in humid weather.
