Fascinating. Given that there's no Lean proof and assuming everything in the paper is correct, can the problem be considered "solved"? Does the paper include a "non-Lean" proof?

I have seen that goofy warning in SBUX stores, for whatever it's worth haha (not on the coffee cup).

I live in SF, California. I think the cleaner gasoline laws are a good thing. Driving a car that emits a high volume of cancer-causing chemicals is obviously bad for everyone. For example, benzene, a cancer-causing chemical, is reduced by ~50% in CA gasoline vs Federal regulations. That's a good thing.

But that doesn't make the tire efficiency rules, as stated, a good idea, as I pointed out above. Less grippy tires -> more car crashes and more human deaths.

Exactly.

Especially "how many more accidents worse-gripping tires cause that result in more totaled vehicles". Forget about the totaled vehicles.

Worse-gripping tires are guaranteed to cause more deaths, all else equal.

California has about 30 millions cars. $1B total fuel savings are … $33 per year, for a whooping less than $3 of fuel savings per car, per month. Thing of all the places you can go with that extra half a gallon, all the work you can accomplish with that large SBUX coffee. It’s all totally worth it.

Study link and/or source?

I don't often laugh on HN, but when I do, it's a big LOL.

Apple Intel laptop + a butterfly keyboard was the absolute gutter tier experience. Not only it was slow and ran hot, but after a few months a random key would get stuck and stop working.

I think the laptop hardware pre Apple M chips was just terrible and has pretty much stayed that way. There’s a reason why Apple moved away from Intel.

Before M chips an Apple Intel laptop was just a shiny wrapper for a PC laptop experience: fans turn on to full blast all the time, battery lasts <3 hours under any regular usage beyond just browsing (say having an IDE open, and frequently switching between apps). Laptop would get hot to the point where you need padding if you keep it on a lap so you’re not boiling yourself. Made for a good leg warmer during the winter though haha.

With an Apple M4 laptop, the only time I’ve heard the fan turn on is when I almost 100% filled the memory with some local LLM model. I can’t recall any other times. Battery life is finally as advertised, can last many hours, laptop is consistently fast, never gets hot and any CPU throttling is not perceptible under medium to high CPU usage.

^^^ This.

What can the Erlang / Golang runtimes do that the JVM can’t?

Boeing and others do complete in that area.

A reminder that both things can be true at the same time:

1. Trump is a bad president

2. The Islamic Republic of Iran should not be allowed to have nuclear weapons
