Stack rankings and curves aren’t anywhere close to the same.

Grading on a curve allows everyone to get a perfect score. Stack ranking means that if everyone is perfect only one person can get a perfect score.

They are in fact opposites.

Also, if half the class fails, that is a teaching failure, not a student failure. The teacher failed to teach the material and/or failed to write a good test.

At Berkeley, if 1/2 the class failed, the professor usually wasn’t allowed to teach that class anymore.

Sounds good1 I assume they have developed their own PCR Assay protocol. Does anyone know the details? Where are they sharing specifics of the test procedure? Are they making a summary of the test results available to the public? How much time is required until someone can get the results of their test?

we are careful to keep the esp clock-gated almost all the time (esp calls this light-sleep), in that mode the power draw of the ESP is on 1.5mA. When the radio (or button press) receives a packet it wakes the main CPU, which then services everything (turning on bluetooth as needed) and then goes back to sleep. If you are curious for more details we have a power consumptions spreadsheet in our docs.

Those interested in A.A.'s official position on atheism and agnosticism should check out the pamphlet[0] Many Paths to Spirituality published recently by AA World Services, the legal entity responsible to North American A.A.. The link is to a product page - click on the picture of the pamphlet to download a pdf. There are sober atheists in AA. To anyone who gets a bad reaction to professed atheism in an AA meeting, remind the offenders of AA's Tradiion 3: "THE ONLY REQUIREMENT FOR AA MEMBERSHIP IS A DESIRE TO STOP DRINKING". If they persist, find or start another meeting.

One of the Utah sports journos has said that their feeling at the time was that Gobert was saying he had no fear of contact with the journalists (forced to be 8'+ from him) rather than wasn't scared of dispersing the virus. Doesn't help much in hindsight and this incident may define him from here!

Aren't all the California universities switching to online or shutting down? That's kind of aggressive, no?

Gatherings are also being shut down. Public meetings are shutting down.

What else would you have them do?
Thanks, that's interesting and not something I've heard before. I think the CDC etc should make this clear : it isn't "an infected person sneezing near you" but "a volume of air into which someone has sneezed in the past few hours". If people knew this I think they would be more inclined to accept the distancing measures.
ah! thanks!
Not bad. Confuses the trim on my robe for a hand. Pretty funny overall.

They’re worth something relative to the revenues they’ve been able to generate.

A company is worth a value relative to whatever a buyer believes they'll generate in the future. The historic revenue is often a useful indicator of what that might be, but not always, especially if the company is operating in a very new industry or if the company isn't very old.
This sounds like something a politically astute developer came up with and built short-term career growth on it at Netflix while the rest of the developers at Netflix look on and say "yeah ok but that's just <FOO METHOD> drawn like a hexagaon. AM I THE ONLY ONE WHO SEES THIS ISNT SPECIAL????"

> Without sufficient testing, hospitals get overwhelmed and death rate skyrockets. Is this "irrelevant".

It is irrelevant to the narrow question of whether the data show that Korea has reduced the fatality rate, which is the point being argued. Deaths from heart disease are irrelevant to the same discussion.

> My Gawd, you are the one who launched the massive detour on fatality rates.

It is not a detour. It is the single point being argued. You made an erroneous claim together with a statement that you intend to repeat it. I corrected that claim to prevent you from repeating it. When discussing that correction, it doesn't matter if you also made correct claims like that 2+2=4.

The worst case of the virus is around 2% of people die, mostly elderly. The worst case of "taking it seriously" is an economic collapse in which a double-digit percentage of people die because global supply chains have fallen apart and there is no longer enough food to feed everybody.

I travelled to starbucks today. I’d hardly consider that essential.
I was lucky enough that mine (late 80s) at least had some acid and magnesium. And although “just burn the magnesium” wasn’t part of the instruction booklet, my dad knew enough to make it cool. We also filled balloons with hydrogen and lit them with a match. Otherwise though, grew lots of copper sulfate crystals...
You basically described PoW (proof-of-work) mining, which was (imho) the actual innovation with Bitcoin. The current idea though is to build a byzantine fault tolerant system that doesn't require massive amounts of "wasted" power. I put wasted in quotes because it is actually doing something, it is just the output isn't useful for much more than validating the transactions.

Interestingly, Maker is currently built on top of (Ethereum) PoW. Some day, ETH2, which is PoS (proof-of-stake), will solve all the same issues you're talking about. Or at least that is the dream. We will then have a pretty amazing digital rube goldberg machine where we can sit back and watch the gears turn.
Sometimes it's not for lack of trying, though. I've done a decent amount of data model design in my career and as I got more experienced, I learned to make a point of asking the business people what specific questions they'd need the data to answer. Very often I got only very vague answers that were of little to no use in informing my design. I've seen this repeatedly at a variety of companies over the years. The business people are often winging it as much as the engineers are.
They said that it was "just steam explosion" and "not nuclear explosion in any way", even though they must (through sigint, atmospheric sampling, and remote sensing) have known otherwise at the time.

Not sure what the demographics of S. Korea is, whether they have a younger population or not, but it's irrelevant.

At least 80%-85% of all Covid-2019 cases have mild symptoms. We are not talking about completely asymptomatic cases, we are talking about a majority of cases that could pass for a mere cold or flu.

Many of those will not go to a hospital or be tested, especially if the system is overwhelmed.

Italy could easily have more than 10 times the number of reported cases because they stopped testing proactively. Only people with difficulty breathing are now tested and these represent a small minority of cases.

I gave S.Korea as an example because AFAIK they are the only ones doing large scale testing of the population and they aren't China (whom we may or may not trust to be transparent).

The data we have points to a mortality rate that's less than 1%.

When you see a mortally greater than that it is because people aren't tested unless they reach the ICU.
You think that should be cancelled?

My experience has been that no one at the insurers nor at medical providers’ billing departments give a shit until state regulators and/or legislators’ offices get involved. Which means yet more time on the phone.

The amount of time lost dealing with this system of ours is incredible. All else being equal it would be a win just to eliminate that, and there’s no reason to suppose that is the only improvement we could achieve.

> Hell, I'm a willing buyer for Magic Leap, at the right price.

You almost certainly aren't. Magic Leap is burning money at an incredible rate, reportedly $50 million/month. Even if you could buy it for $1 over their cash on hand, you'd be a fool to do it, as you'd have to spend the next several months laying people off, negotiating with creditors, liquidating assets, and fending off lawsuits. It would be miserable, and there's a good chance you'd have little to show for your time.

Any serious buyer would expect to put another couple billion in cash in just to get it to where it has a product people will actually pay money for. I'm guessing that isn't you.
I don't know it seems like it might be dumb to make an exception that would be hard to check and thus might be hard to apply and would mean that anyone who didn't want their comforts interfered with could say "I'm an immediate family member!"

But I guess the ethical will follow the rules and be uncomfortable, and the unethical won't, as per standard operating procedure.

During undergrad, I worked with permanent magnets in a plasma physics laboratory, mostly using them to build instrumentation to accelerate gas plasma plumes for spectrographic analysis. This sounds neat in principle, but I'm skeptical of any meaningful application. Dealing with permanent magnets of any meaningful size (let alone arrays of them the size of which would be required) becomes extremely dangerous, and requires a lot of care and attention to detail. Especially considering some of the progress in lowering the cost of high-temperature superconducting magnets, this might be a tough sell. I'm curious if there are any statistics for accident rates of magnets vs. cryogens like liquid nitrogen in development environments.

I have a few friends that teach at K-12 schools in California and they've all been told to figure out what platform they want to use to do teach remotely. Our local school district sent out an email to parents outlining an online teaching plan.

Remote company founder and lawyer-to-be here (just finished the finals - hopefully, I've passed!)

Labor law is local. If you hire someone in a different country (say, Sri Lanka) and things go south for whatever reason, they can sue you in the relevant local court.

To re-emphasize: by hiring an employee in that country, you've submitted yourself to the jurisdiction of the labor courts of that country. This supersedes and replaces any language you might have in the employment contract about the jurisdiction of employment.

Of course, enforcement is a problem. If a court in Sri Lanka issues your company a summons and you ignore it, the legal consequences will be limited (although you might be arrested if you ever visit that country). However, if that employee is located in a major country or bloc (e.g., the European Union), not being able to travel there ever again is a high price to pay.

In nutshell, this is why many remote companies are careful about hiring in foreign jurisdictions. The potential legal complexity is probably not worth it.

Counter-example: "You may not print that--the President doesn't like dad jokes."
I agree with your analysis, and I think the fact that they've struggled to actually bring a compelling product to market at a price point that attracts consumers (outside of the technology bubble) means that, even if they had the best of intentions at disrupting the market for innovative user interfaces, either they are another Research In Motion (great product, with a long-term idea that wasn't quite ready for primetime yet), or just another side show that won't end up being culturally relevant beyond the passing captivation that individuals felt upon watching their "whale stadium" mock-up video.

In retrospect (at the time, even) it felt like complete BS. If you look back at the threads posted on HN, I distinctly remember people calling out their methods as super vague, and probably completely fictitious - amazing to see that the angry, dismissive comments actually turned out to be the most factually based!

The problem with Magic Leap is that it was always vaporware. I think the second you start using 3D CGI to "show what the product will be like" you're already kind of fucking up. I mean I get it, if youre building a concept car, you can't just immediately build it. But Magic Leap's videos were always like "yeah literally, it'll be like you're in Avatar."

Give me a break. I hope some mega-corp eats up the IP for like 7 cents on the dollar and actually uses some of the tech for something that sees the light of day.

Organise the Paper
I read in another thread that sneezing aerosolizes the payload such that it will stay in suspension in a large volume of air (a large room for example) for hours. I'd call that "airborne transmission" but it seems that means something different. That being the case, could it be that the hand washing is more to do with reducing the surface area onto which a droplet can land and make it into the target's body? This would explain quite well how someone can infect 50 other people in a large room, and also why hand washing is helpful (but not a 100% protection since droplets can still float in through the nose and mouth).

If religion just "isn't your thing" I'm pretty sure that makes you an agnostic not an atheist.

However the majority of atheists in my exerience are a bit more mellow. You can fully believe there is no grand deity without being "hostile" to the belief.

As an example (that maybe is more generally relatable): I believe the world is round. I don't think I am hostile to the flat earthers. I think they are wrong based on evidence, but their ideas don't disgust me. I don't want to burn them at the stake or harass them. If they leave me alone I am content to leave them alone. So I dont think i am hostile to their beliefs. However i would never describe my relationship to the flat earth "theory" as "just not my thing".
> It isn't hard to understand what the President is saying

The problem is that the public at large will internalise the first interpretation they are presented with, whether this be their own understanding or their favourite news outlet's. Past presidents were smart enough to realise this and therefore appointed professionals (whom they listened to!) to help them craft their messaging to be as precise as possible. Trump, for some reason, has failed to learn this lesson in his first three years on the job. It is because he continues to use inprecise language that his messaging gets corrupted like this.
