One tiny nit on this amazing project / write up. He mentions that the traces have to be extra wide to support 24V. In truth though, the higher voltage means lower current, which means if anything the traces can be less wide. The size of the traces is determined by the current they carry, the voltage determines how much space must be between the traces (but it’s unlikely to be an issue at these voltages).

What so many people fail to realize is the true purpose of money is to avoid having to spend time with people you don’t like, or do things you don’t value. So if you have a $400/million per month job, but you have to have meetings all day long, you’re not really rich. Similarly, no offense to billionaires, but the ones I’ve met have been someone manic and misanthropic. If you are using your access to spend your time with them, you are not really rich in my book.
True wealth is being able to spend all your time doing things with and for people you love. It sounds trite, but the truth is many people miss the opportunity to jump off the train and enjoy their life while they can.

You can tell a company really builds using their own products when an abuse system can take them offline!
I see the forbidden terms include "gender" and google scholar returns 5.3 million results with that. It's all a bit silly. Next they'll ban European languages for being gendered.
They actually like male/female enforced gender. Maybe what they’ll do is add gender to English grammar!

This is neat, but as a $NET shareholder and someone with another ~$1m in net worth that can't afford to buy a house for at least another 6 years this makes me think we should significantly increase taxation.
If you’re a Cloudflare shareholder, Kenton has increased your net worth quite a bit. He is one of the few people who is so unreasonably capable he can and has changed the direction of a multibillion dollar company single handedly. It sounds hyperbolic, but it’s not in this particular case.
I’m also fairly convinced he didn’t capture one tenth of one percent of the value he created, so I’m not sure how anyone can argue this is ‘unfair’.
If you are a SCUBA diver, but always wished that diving was a bit more technical and rigorous, I highly recommend trying cave diving [1]. You can do a cenote tour in just an afternoon, and if you’re hooked a few weeks of training (spaced over time) will make you into a radically better diver.
They lost me at dropping hot oil. There is no evidence of anyone dropping oil, it would have been expensive and hardly better than boiling water.

Edinburgh is such a walkable city, I had a fantastic half a decade living there
(without a car, apart from the rental one when moving there). This sounds like
the right move to maintain the pedestrian-friendliness and to keep the air cleaner.
However, the houses there are often old/historic, with very inefficient heating systems (some even use electricity to heat up a bunch of bricks, which then emits the heat to keep warm) - shocking! Also, windows are not normally with double or triple glass, and sometimes it is not permissible to change these because many buildings are protected.
Those brick heaters are smart because they use electricity at off-peak times to heat the house for the whole day. What about it strikes you as less efficient than any other direct electric heating?
I haven't grok'ed things properly yet, its a hefty read for my Monday morning, but the thing that leaps into my mind is to ask you why Javascript, of all things, and not something like Lua?
Isn't Javascript just too finicky for something like this? Are other languages/approaches to integration with the execution environment possible/feasible?
(I apologize for my newbie question, hope you don't mind..)
What’s your definition of finicky? JavaScript is something like 3-10x faster than Lua for most benchmarks (1). If you’re referring to the event loop, it shouldn’t be all that relevant for singleminded code like this that is only processing a single event every half second. If you’re referring to mathematical oddities, it is also not relevant as JavaScripts love of floats is well suited here.
