Interestingly, Matt has invented a variant on the retpoline [1] which _intentionally_ missteers the branch predictor to prevent various speculative attacks. (Invented by my former Google manager.). It's pretty cool how much simpler a retpoline would be in aarch64, since we have explicit control over the link register rather than having to play stupid games with stacks.

(Real retpolines have a little more magic, naturally.)

In 2021, New Yorkers filed the most complaints about engine idling since 2018: 13,489 complaints. The police issued 75 summons in response to complaints, data shows. Specifically, police issued 14 summonses for excessive vehicle noise — the most between 2018 and the present, a period in which the police issued a total of 26 excessive vehicle noise summonses.

There is one dude who drives past my window on 6th Ave, every single morning, at 7 AM, with an engine so loud it rattles glass ten stories up. That should be 365.24 summons/year, _for that guy_.

Until the cops choose to enforce the laws, nothing will fucking change. I'm thrilled the government is claiming to care here, but until anyone chooses to have these people hanged from the yardarm^W^W^W^W nothing will fucking change.

By the way, did you know it is _illegal_ to honk your horn in NYC outside of an emergency? Neither do the the people honking constantly outside my window! Why doesn't the NYPD just fine all of these people every single day until it stops? They could fund the entire department! But they simply don't care.

Many of my friends dream happily of enforcing vigilante justice for the loud motorists. I personally would be thrilled if this guy:

But Pennachio conceded he has modified four of the 11 cars he owns to enhance the rumbling of the engine, as a matter of pleasure, not safety. “Just to know you’re in a beefier man’s car,” he said.

was evicted from the city. He is a horrible person with no redeeming characteristics and doesn't deserve to live in society.

You are welcome to advocate for pleasant, humane prisons. Run whatever antirecidivism campaigns you wish there. If they work, that's great.

In either case: send people who commit crime to those prisons. If they do it again, send them back.

I think you're misinterpreting GP: even though it is true that possession-like crimes are badly handled by the US, you can erase them entirely and the US _still_ has a larger prison population. Our population commits more real crimes than most first-world countries. Treating addiction like an illness seems nice, but will not stop that. We either must imprison them (which don't do _enough_) or convince them not to commit crimes (which actually prosecuting crimes _might_ help with, and very little else we've tried does.)

That's nice. Feel free to fix the prison system at any time; if the people who come out don't commit more crimes, I'll be happy.

In the meantime, imprison the people who do commit crimes, and if they do so again after they're out, imprison them again.

Because it's fun, easy, and beats working.

Unless we arrest, prosecute, and imprison them. Or punish them other ways; how about flogging? It's arguably both a better deterrent and more humane than prison.

Saying "Sure, go ahead!" is better for no one.

If only 1/5th of those prisoners are there for drug-crime (and I assume you believe as I do that much drug-related crime isn't worth the arrest?) then isn't that in fact evidence that our population commits substantially more _real_ crime than in other countries?

If so, then yes, let's lock them up. "Everyone steals" is not a good defense to stealing.

The causation is backwards!

I'm not an alcoholic but I am an anxious wreck. Single best way to make me stop freaking out at a party? Two old fashioneds.

I'd prefer to be gregarious and unworried sober, but that's not an option. (Yes, there are other approaches. This works better than all of them.)

I can confirm we came up with this optimization inside tcmalloc, and our compiler experts nacked it as unsafe, even only calling tightly controlled code. A pity, as it is really beautiful to see the improved clobbering (and even, in some cases, hacked calling conventions.)

Mostly market driven (I expect there are some regulatory concerns too but I don't know any offhand.) What this means is that there are very few holders of TSLA stock who are willing to lend it compared to the number of people who'd like to be short. I'm not sure precisely what that does imply about the people holding it; typical institutional holders do happily lend out stocks, which is why typical short financing costs are low.

Is your garage actively ventilated? Mine (in my previous house, I live in an apartment now) was a closed room with a pulldown door (always closed) and a window that didn't open. It's not hermetically sealed, but how confident are you it wouldn't become saturated with N2 gas?

Don't get me wrong, I have internet friends. It's just hard to treat them as first-class people compared to those I know in person. It was way easier as a teenager--I didn't have in-real-life friends! Sigh. If you were going to maintain primary internet relationships, close-knit as can be, I can imagine worse ways to do that regular team gaming.

I don't think that all in-person relationships are better. There are people I see in person ~regularly I loathe. (Obviously, most such people I try not to see anymore, but you can't always control your friends' friends, or your coworkers, or who goes to your gym, or...) But they're all more real.

Consider the hypothesis you have an anxiety disorder, not introversion. I said I was an introvert for years until repeated evidence (and everyone I know pointing out to me) convinced me that I am just happier, healthier, and have more energy if I'm around other people. That doesn't imply that I (or you!) am _good_ at being around other people, especially strangers.

It's hard!

Humans don't have emotional object permanence.

My ex-girlfriend described herself this way to me once and I thought it was funny, but it's in fact true of people in general: if you're not physically present near them, they will forget that you really exist as a human and a social peer. It's unfortunate but it's true: you are going to naturally think more about and have better feelings about the coworkers you see every day in person. No, VC doesn't count. I think this is pretty much a human universal; the only exceptions I know are quite far on the autism spectrum. (Even I notice myself doing this, and I'm definitely somewhere on that line.)

Given that, I want to be in the room with my coworkers. I want them to unconsciously think of me as part of their tribe, and I want to feel the same way about them; that means we need to be able to perform regular in-person social petting. This is doubly true of my bosses. It sucks, but there's no way around it.

(Also, while this is less universal, there are plenty of extroverts, even on HN. I'm one. It's ironic, in that I also suffer from pretty nasty social anxiety; large rooms of strangers scare me and choke me up. But lock me in a room by myself for a month and I go crazy. I am happier, by far, when I can be in the same room as people I like.)
