Psychosomatic illnesses are in fact quite serious, but they require psychological treatment, not lockdowns of society.


"Results: Patients with post-COVID syndrome scored lower for emotional stability, equanimity, positive mood, and self-control. Extraversion, emotional stability, and openness correlated negatively with anxiety and depression levels. Conscientiousness correlated negatively with anxiety."

The incidence of heart attack and stroke increases significantly after COVID infection, so please spare us your appeal to “psychosomatic illnesses”:

(I should get bonus points for this being a Swedish study as well, since every COVID denier loves to wave around their flag.)


God, do I love working in the finance industry some times.


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.)

> Do they have special interview channels for 'regular devs' and another for people who can write dynamo ?

Not special interviews, but certainly different pieces of headcount. There are Googlers and there are Googlers. Being the second is a lot more work, but a lot more interesting.


I’d love to know more about how one gets to be in the second group at all as a non-Googler - might make working at a FAANG worth it.


The way I went: First get good at algorithms in some way. Then you join an unsexy infrastructure team at Google, there are tons of hard problems and potential for impact there. Then you use your accomplishments from the unsexy infrastructure team to join a sexy team, even at Google the kind of people who can actually improve the hard parts of Google are rare so that move isn't hard to make.

Some people directly join sexy teams, but that probably means they have some accomplishments from before, the hard part is getting a foot in that door and the unsexy infrastructure teams are a great place to start since there are tons of problems to solve there and not much competition for that kind of work. Most people just want to work with data models or publicly visible products, not the invisible services that moves millions of requests per second, but anything that moves millions of requests per second will be easy to have impact with.


What about the Tu-95? It's famously loud due to (says Wikipedia) supersonic propeller tips. Do you know why they're still effective?


I am convinced that if you were to dimple the propeller (tips) such as a golf ball is pitted, you would reduce this effect.

Further, if you wer to dimple/convex in an alternating pattern the leading edge of any aero ... efficiencies would increase.

Micro-dimples are better.

Understand the eddys, as Da vinci would say....


The Tu-95’s props are paired for counter-rotational torque balance. The second prop does not add additional thrust.


The supersonic speed was the question, not the contrarotation.


Well, samstave's original question was one of adding power with an inline stack. As I understood it, that isn't the purpose for he Tu-95's pair of props since they share a power source. The below explanation [0] has some interesting analysis based on Russian language documentation about how torque is divided between the prop pairs. Additionally the paper linked from the Wikipedia contra-rotating prop page "Analysis of a contra-rotating propeller driven transport aircraft" [1] has a great section on fuel savings, which probably has contributed to the Tu-95's success.

Thus, the front prop gets almost 20% more torque than the rear prop.

Thank you all TIL so much.


I believe they're sacrificing efficiency for performance.


It's the transition that kills you. Are you doing this full time?


My full-time thing is more search-y and takes tens of milliseconds so I'm not really sweating power state transitions that take a few micros.


I don't know anyone whose house has burned down. Should I cancel my home insurance?


> 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.


I don't know how your windows are made, but you can't really use glass to gauge the sound level of noise. If it is in anyway loose, it acts like a very rigid speaker diaphragm. It moves back and forth with any sound, since glass basically doesn't flex. What you're actually measuring is your own ability to perceive its movement.

As far as fining motorists for horn usage, if it works like everywhere else in the US there is no way they could ever actually make good on the fines. As long even a small percentage of people requested a court hearing (doesn't matter if it is a jury trial or something else) the police officer would basically spend 1 day writing fines, the remaining days in the year just sitting in court.

I'm unsure though, maybe NYC has a provision allowing it to issue fines you can't contest.

Confiscate their cars, problem solved.

Fairly certain such a scheme would be illegal.


Does due process apply in the US to just fines? My understanding is that due process only applies when the government intends to deprive you of life, liberty, or property. I don't think a fine paid in currency falls in those categories.

For example I've gotten parking tickets that had "automatic" hearings with no judge if you requested one. Unsurprisingly, they tended to find in favor of the government.


Get it covered under civil asset forfeiture somehow. If our rights are going to be trampled anyway, might as well be some social benefit.


> By the way, did you know it is _illegal_ to honk your horn in NYC outside of an emergency?

I had a next door neighbor, someone picked their kid up from school every morning about 7:00am. Every morning, the car would pull in to the driveway between our houses and lay on the horn until the kid came out.


https://research.google/pubs/pub50370/ gives more up to date information, as does the slide deck here: https://docs.google.com/presentation/d/1taP_gqeRE1XGB2td7f32... (We get down to 4% on the graph on slide 3.)

It's far below 10% now (thanks to the hard work of a lot of people), and Google actually gotten to the point where we chose to spend _more_ time in malloc to make overall efficiency higher.


If they spend time in jail after the first time, maybe they won't become a habitual thief.


In fact its impossible to steal from a CVS while in jail.


Nah, prison is where they learn how to get away with it next time from hardened criminals.


I don't really believe on that theory.

On other hand whole being marked felon thing is what really destroys the future. If you can't get a decent job, what options do you have left?
