Nice! Needs just a tweak to prevent the overshoot and bounce when going from high to low.

So I haven't watched this video. But in the age of deepfakes, with a click bait title, why should I believe video anymore? Especially "rare, lost" ones? And presumably ones with a point to push? What do HNers do to assess the provenance / authenticity of video in 2026 and beyond?

floxy — Tue, 12 May 2026 22:42:35 +0000

The time-honored way of learning about monads is to write a monad tutorial. Monads provide an order dependency (that along with some hidden strictness for I/O and the like) which allows the side-effecting to be isolated from the "pure" functional side of things. The purely functional Clean language had an explicit "world" variable that you could pass around to whatever side-effecting functions you wanted. And it had uniqueness typing so that you couldn't accidentally refer to the same "world" twice. You can think about monads as being a way to hide the crufty "world". A lot of the mystery around monads comes simultaneously with a whole bunch of other newness in learning Haskell (lazy evaluation, HM type system, differing syntax, algebraic data types, currying and partial application, functional programming, etc.).

There is a similar vibe with TIG welding as well.

>A proper reflow oven is better, of course, but that's pricey.

You can do a lot worse than a $55 temperature controlled hot plate. Plus you can watch the magic happen. Of course that only works for single sided boards. I've been very impressed with the results.

Washington State has grocery stores that sell fountain drinks. Yoke's:

...also WinCo Foods. Or at least the closest one to me does, right next to the in-store pizza counter.

I wonder what ever happened with the stream poisoning effort on a creek that ran through his ranch. That was bit of a thing growing-up back in Montana in the 90s, where the billionaire outsider wanted to poison the stream to kill off one species of fish to encourage another species.

Isn't the concern with over the air updates and back-doors? As in, if the citizens in county A buy country B's cars, and now there is a tiff between the two countries, country B could potentially brick all of those vehicles in country A.

Hmm, why not? For the astable configuration, you could use a 100F capacitor with R1 = 10 Meg and R2 = 7.5 Meg, for a 55 year period. Base current for the Threshold NPN will come from the Trigger PNP (and hopefully temperature drift matches OK). Other than maybe the 100F capacitor might have some variation in capacitance and leakage current over the course of 55 years ;-)

syntax-case is the general purpose construct to use. syntax-rules is a restricted, easy-things-should-be-easy construct.
