Jim Roskind had a really nice talk [https://www.youtube.com/watch?v=_uaaCiyJCFA] at AWS Reinvent 2022 which highlighted the fence post problem. Basically, AWS was targeting P50 and P90 latencies in many services, and sure enough there were big clumps of latencies right under those target fence posts as engineers were basically gaming the metrics and nerfing the >P90 latencies to make it happen.

That makes sense, and is a fine approach.

I'm of two minds about this. Facebook and Instagram keep me connected with friends, new and old. True, they're filled with algorithmic crap now, but when I tried ditching them for a while, it didn't improve my connections with people. If anything, I lost touch with people because that's where they were. I'm much better off knowing what my friends -- many who have scattered -- are up to, and giving casual updates myself.

On the other hand, yes, absolutely put the phone down at the dinner table and engage with those who are present. No questions there.

Finally, my kids are getting to the age where their friends have phones and use them to communicate. My kids don't yet have that and are reliant on me to text parents, which is a lot of friction for everyone involved. Their summer is very boring because they hardly get to see their friends. So, sure, fight boredom by entertaining yourself, but that's a lonely existence.

Semi-serious answer: No, the company only gave themselves the right to unilaterally amend the terms, not you.

Sadly, this bill has been around since 2007, introduced by the very same Hank Johnson! I would love if Congress would put an end to the forced-arbitration bullshit that so obviously does an end-run around your 7th amendment rights and makes a farce of informed consent, but alas, they couldn't even get it through when Democrats held the presidency, the house, and 60 seats in the senate.

The big two, x86_64 and arm64, have 64-byte cache lines, so that's a reasonable assumption in practice. But I was surprised to discover that Apple's M-series laptops have 128-byte cache lines, and that's something a lot of people have and run, albeit not as a server.
