My money is on the social smoking as the main reason for the drop. Social distancing leads to less smokers.
It comes down to how much surface area your cooler has (whether that's radiator or a cooler tower) and how much air is moving over it.

There is no magic about a water cooler that reduces noise. It is a thermodynamically determined process. The fin stack has a certain temperature, there is a certain amount of surface area, and a certain amount of air moving over it (at a certain temperature). A radiator really gives you no significant advantage in any of those areas. In fact a lot of radiators actually have less surface area than some of the really big air coolers like NH-D15. They are only maybe a couple centimeters thick, the D15 is about the same size as a 140mm cooler but the fins are four times as thick.

On top of that you have pump noise. An expensive custom loop with a nice quiet pump can reduce that significantly, but AIOs in particular are just never going to be quiet because of the pump. The "pump" on an air cooler is evaporation itself - the working fluid vaporizes on the coldplate (and cools it) and then condenses on the cooler part of the heatplate where the fins are cooling it. This is basically a "silent pump".

The best you can say about a radiator is that (a) by putting it on an intake you can guarantee that the air it's sucking is slightly cooler rather than being warmed by the ambient heat of the case, albeit with the downside that you are now pumping hot air over your other components, and (b) you can put the radiator in a more convenient location than sticking straight out of your motherboard.

(you can of course skip fans entirely! check out the HDPlex H5, it is a cool case where the entire thing is a heatsink, it uses heatpipes to move the heat to the chassis and the chassis itself is finned for dissipation. I have no imminent need for it but I lust for it anyway, it's just so damn cool.

Pretty close. It was a professor that was tired of people writing languages to embed in their applications, so he wrote a language to embed in applications.

Very much an XKCD 927 story.
incorrect; smokers are shown to be substantially less susceptible to both catching covid and developing severe symptoms, a finding that has been demonstrated independently in (at least) france, china, and the USA:

> Conclusions and relevance: Our cross sectional study in both COVID-19 out- and inpatients strongly suggests that daily smokers have a very much lower probability of developing symptomatic or severe SARS-CoV-2 infection as compared to the general population.

> Very recently, the US Center of Disease Control reported an analysis of current smoker rate among US COVID-19 patients which was found to be 1.3% for the whole population of COVID-19 patients, 1% for outpatients, 2% for patients, not hospitalized in an ICU, and 1% in intensive care unit (ICU)-admitted patients

https://www.qeios.com/read/WPP19W.3

in all of the mentioned countries, only about 1% of ICU cases are smokers. this has (perhaps unsurprisingly) not been widely reported.
I am not convinced by the gini fit. There must be something else.
Apart from that: because of not keeping up with stats, i always thought that south africa has the most murder per capita (apart from war zones). What has happened: Jamaica is almost double. Did SA get better or did central america take a significant slide downwards?

I don’t know about “resistance to anxiety”, but it can certainly be anxiety-inducing to be the only member of a given minority in the interviewing room (or entire floor, as is sometimes the case in tech).

No it won't. All these federated protocols are doomed to die out of spam, centralization, censorship churn.

People really have to watch what Urbit is doing and understand why. Anything less is insufficient.
Very intriguing idea. I’m thinking about how logistically this could actually work. It would build a sense of camaraderie as well.
> therefore (4) nothing needs to change.

Again this isn't very charitable. I've had many of the same discussions and very few people I've debated this with come to the conclusion that things don't need to change. Most agree that things need to change, but they conclude that different changes are warranted than you do.

Many people today focus the change on step 2 ("police will naturally interact more with black people") with policies like defund the police, while others might focus on changes that change the step 1 ("Because black people commit a disproportionate amount of violent crime"), while others even still will focus on things the are priors to even step 1.

Disagreement on the change required is perfectly normal and to be expected. Just because people disagree on the change and don't see things exactly as you do doesn't mean they don't care or are bad people.
I have basically been doing a second job sending out applications and interviewing hard core for about a year now. There is so much time I have accumulated in take home projects. Anxiety is a big issue for me interviews(Yes, I am a woman) and even in ones that go well I am still clearly minorly affected by it. There was one back in November that I got to the stage of being flown out to their office. At the end of the interview during small chit chat I was nervously talking about the stickers on my personal laptop.(My plane had been delayed to weather and I was basically interviewing with them a couple hours after everyone would normally stop working.)

My count on applications is well past fifty and I have done so many phone screens(HR and technical) that all of them seem like a blur to me. At this point I wish I could throw a portfolio of my work at a company and get a job. From a Reddit thread about "unrealistic car mods" shows my overall skill set in my ability to get the job done. https://www.reddit.com/r/cars/comments/hdrgv1/car_people_of_...

My current job I got because I found a major vulnerability in the company's authentication system and recovered the private key for the client to server encryption.(I didn't make much money at the time and didn't want to pay the subscription cost for the premium service.)

I have interviewed/hired nearly every person on my current team. One of them was almost denied by a senior manager because the candidate wore a backwards baseball hat during the interview.(Lack of professional attire, etcetera.) The rest of the interviewers over ruled the manager saying that was a dumb reason. Turns out this candidate was super conscious of a balding spot on his head and he wore hats to hide it. He turned out to be an amazing coder and great at solving problems that came up.
Could be frequency, could be magnitude of the gestures, could be the gestures are more prominent/memorable/not subtle. Probably a combo, or, it's possible that the stereotype was centered around a few prominent individuals and is not actually a trait of that languages speakers.
Patients who die of coronavirus have median age of 78[1], and thus life expectancy around ten years. Younger decedents will have a disproportionate effect on average life years lost, so using the median life expectancy does tend to underestimate that. On the other hand, the patients who die were probably less healthy than the average for their age before they got infected (e.g., the huge mortality in nursing homes; nursing home patients already had an average life expectancy around a year[3]), which would make us overestimate. Somewhat arbitrarily, let's say those cancel, so a coronavirus death costs ten years of life.

The average IFR over all ages is 0.7%[4] from a recent meta-analysis. If we're considering prospective smokers, then I guess we should exclude young children, so let's (again, somewhat arbitrarily) bump that up to 1%. That would mean a coronavirus infection in a random individual (age weighted according to population of prospective smokers) costs 0.1 years of life expectancy.

But smokers have life expectancy about ten years[5] shorter than non-smokers! So there's lots you could find to argue about in my rough calculation above, and I agree that patients who don't die immediately still lose some yet-unknown number of quality-adjusted years of life; but unless you think you can find two orders of magnitude, smoking is unquestionably more dangerous. That doesn't mean the coronavirus is harmless, just that smoking is really bad.

Ask HN: How do you build dashboards to monitor your ground teams in a city?
Hi HN! If you belong to a company with any ground operations, how do your city and ops teams measure area performance?

Do you have an internal dashboard or do you use a BI? If you have internal dashboards, how do you update metrics on it and maintain it?

If you use BI, how do you go more granular than areas? I am talking specifically about orders, routes, users and so on!

One thing I started to worry about and which wasn't addressed is that the technique of wrapping the cable around the power line hinders power line repair or could preclude future applications like this.

Twitter: Our investigation is still ongoing but here’s what we know so far
Take home interviews should be paid, like 200$ and not require more than 4 hrs.
Correct. In many of these companies, part of your evaluation is how many interviews did you give. This means: the game is to do as many as these interviews, typically once a week, such that you are not penalized for doing too few interviews.

I was once penalized for giving too few interviews but there weren't enough candidates at that time! While I cared about giving every candidate a good chance for success, I can say confidently that not many did care. They only cared about getting credit for doing the interview.
There are people on /r/wallstreetbets who are blowing up 100k accounts on TSLA puts on Robinhood. On the front page of /r/wsb right now the 3rd highest post is someone who has lost 30k gambling on TSLA.

Even betting 20k would have probably netted you more than what was gained via BTC and you would still be indistinguishable from RH day traders.

“Sales taxes are the most regressive form of taxation,” the supervisor contended, meaning they hit low-income people as hard as wealthier residents. “This is a railroad that, while it is an extremely valuable public transportation resource, serves a very affluent clientele.” In an interview later, Peskin pitched an alternate idea: Why not impose a regional tax on “the wealthiest people in society who are more likely to use the railroad?”

To claim that a rail service in car-first United States only serves "the wealthy" is a bald-faced lie. The idea that it is only the "wealthy" who use CalTrain runs totally contrary to my experience on the train system - what I've noticed is that the "wealthy" pay their fare (overpriced - $20 just to go from SF to Palo Alto and back!), while the "less affluent" clientele often hop on and off without payment. I do see people of all incomes use the train, especially when I sit in the bike section - less affluent people need the CalTrain especially because it enables them to bring their bicycle with them (not reliably so with buses that only have space for two bicycles), and a bike is a must for anyone not fortunate enough to have a car in the southern part of the Peninsula.

So I think this next bit is on point:

Such arguments rankled Adina Levin, executive director of the grassroots advocacy group Friends of Caltrain. “This is a circular argument,” Levin said. “Caltrain does not have stable funding, and so it’s raised fares. And that means the riders are higher income.” She pointed out that a share of the projected $100 million-a-year revenue from the sales tax was supposed to fund discounts for low-income riders.
I think it's the monolithic nature of it.

I've been running Fedora LXDE lately, which worked fine for a while, but then I broke my own rule of never upgrading something that's already working.

Now, I have the same issue you describe occasionally. My whole desktop freezes up, and I can't do anything. It seems to happen if I'm running my screencapture script and switch desktops at exactly the wrong time.

However, the desktop is not the OS, and is isolated from it quite well. I can still press Ctrl+Alt+F2, switch to a completely different "environment", and start killing processes until I get the one which causes the issue. (Seems to be the `import` command.)

On Windows, similar to Mac as well, there is no such separation. Everything is integrated into one big blob, and once that's broken, that's it.

Maybe it's because it is all developed together as one thing, whereas in the gnuli world, the kernel is developed without assumptions of any particular thing running on top of it?

I concur. I did BP for only 1 semester in college but the experience proved to be valuable down the line. It forces you to articulate yourself "on the fly", streaming out ideas as they are formed (from core principles / bullet points you have in your mind).

Article I, Section 2 of the constitution requires the government to conduct a decennial census, and empowers congress to make such law as it may direct to implement it.

One could easily see a national identity system to be justified as part of the census. I'm sure there are other articles that could also be used to justify one.

The reluctance around a national identifier and system is purely policy, not lack of constitutional authority.

Hanford is just $6 - $10 billion per year, with cost estimates up to $667 billion total over its "lifespan", but we know some of the nuclear waste will be with us for thousands of years, so this number will only get bigger. There is no end in sight.

WIPP also had a leak issue with cost estimates of up to $1.4 billion to fix.

There are also dozens of sites orphaned and essentially the problem for the DOE to figure out. The cost of nuclear waste has been heavily socialized. The problem won't be going away anytime soon.

Illumina error rates are <<1% (~0.1%), whereas Nanopore with newer basecalling software is 5-10%. With UMIs you can get a consensus error that's also <<1%.

I didn't find their case to be well made either. But what they are asking is for Pinker to not appear to speak in their name. They state explicitly that they don't request that any of his public discourse to be removed or censored.

This doesn't seem to be an example of cancel culture to me, because it is not an issue of freedom of speech or of opinion vs audience sensibilities. It is an issue of representativity.

If the letter states explicitly that they don't question Pinker's right to free speech, then in my view the article misrepresents the argument by talking about an "outcry over free speech".

For what it's worth, I don't personally believe that the right solution is to remove Pinker from that position, but rather to aim to increase diversity among the fellows of that society. But then I'm not a member of the linguists' society, nor even a linguist so I also believe that my personal opinion shouldn't matter here.
