  • One of these is near me, and my parents fell for the bullshit. So now they’re incrementally more afraid for me, because this store is making shit up, and the media is uncritically parroting it.

    That target was within a block of two grocery stores and a drug store, all three of which had bigger signs and more parking. Also it was inside a building whose doors locked two hours before the Target closed, so nobody could get inside it. Also it’s a fancy building that almost certainly charges them higher rent than their competitors are paying.

    Yeah I’m sure it’s theft, and not the fact that you decided to open a store nobody could get to on expensive land surrounded by competition.







  • Air is a compressible fluid, so ultimately you’ll need Navier-Stokes, but actually figuring out how to translate those equations into code is infamously annoying, so definitely check out an existing solution instead of trying to implement from the equations. Foster & Metaxas is an old a grid-based solution. Theirs is designed for incompressible fluids (water), but I think it should be fine if you raise β₀.

    There’s a lot of math in the paper, but it’s easier to implement than it looks (each step, run [2] on every cell once, then run [6] [7] [8] on every cell ~6 times), and it’s mostly just transcribing equations. It’s super fiddly though, just incredibly fiddly, expect to have to spend a lot of time debugging.

    There are probably suitable simpler solutions too though, so definitely spend some time searching for them (or just copyable implementations of Foster & Metaxas) before diving into that.
