The guy is not known for junk science:

Professor Hendrik Streeck, director of the Institute of Virology at the University Hospital in Bonn

https://en.wikipedia.org/wiki/Hendrik_Streeck

Streeck studied medicine at the Charite University, Berlin and obtained his PhD from the University of Bonn, which he performed part-time at the Partners AIDS Research Center, Massachusetts General Hospital, Harvard Medical School.

After his graduation Streeck started to work as a postdoctoral fellow at the Ragon Institute of MGH, MIT and Harvard. In 2009 he was promoted to Instructor in Medicine and in 2011 to Assistant Professor at Harvard Medical School. In September 2012 he was recruited to the United States Military HIV Research Program, Bethesda, where he became the Chief of the Cellular Immunology Section as well as Assistant Professor at the Uniformed Services University of Health Sciences and adjunct faculty of the Bloomberg School of Public Health, Johns Hopkins University.[3] In 2015 he became the Chair for Medical Biology at the University Duisburg-Essen and founded the Institute for HIV Research in the same year,[4][5][6][7] though he still maintains the status of "visiting scientist" with the US Military HIV Research Program.

In 2018 Streeck was appointed to the advisory board of the German AIDS Foundation (Deutsche AIDS Stiftung).[8] In April 2020, he was appointed by Minister-President Armin Laschet of North Rhine-Westphalia to a 12-member expert group to advise on economic and social consequences of the 2020 coronavirus pandemic in Germany.[9]

Coronavirus research

In early April 2020, Streeck and his team reported that they had "carried out an intensive search of the home of a family infected with the coronavirus but found no trace of it on surfaces."[18]

“We did not find any live virus on any surface. Not on cellphones, not on taps, not on doorknobs.”

There was the Kindle DX which was 12.6" on the diagonal IIRC. I guess that's still a bit too small though, and the last model of that came out a decade ago.. I'm guessing it didn't sell well because I've never seen anybody using one.

They just found RNA of the Virus not an active Virus, there is a huge difference. Same goes for Virus in stool, you can detect the RNA but it’s not active anymore. Source: Webasto Study
There is already precedent of somewhat magical syntax changing the return type, namely 'async' making the function return a future<your stated return type>. While this approach adds one more non-obvious thing for a newcomer to learn, it shouldn't make it much more difficult to reason about your code once you know what to expect.

> I think you might be surprised what people would be willing to give up to live in a crime-free society.

1. Very often, they're quite willing to give up _other people's_ privacy.

2. Have you considered what many people are willing to give up to live in a mass-surveillance-free society? Probably not, because we're never given these options for serious considerations and for us to choose. It's a false dilemma - the state makes the decision, eats away our privacy and uses things like pedophilia as the excuse because it's scary.

3. Let's start with making some sacrifices to prevent criminal behavior by elected officials (Trump family, Biden family, Bush family, Clinton family - I'm looking at you people), and in high finance (2008 crisis racketeers who never faced any criminal action) and once that's sorted out, then let's talk about what more needs to be done to achieve a "crime-free society".
> I would love to improve any part of this article, if possible!

You should state that the reason the neanderthal version runs faster is that it is doing the computation in lower precision than numpy / cupy.

The article walks through an investigation of why cupy's result is underwhelming (is the input data accidentally fp64? is the input data on the cpu? is the computation happening on the cpu?), so you should finish it by explaining that numpy and cupy do the computation in fp64.
Thanks for sharing.

I'm interested to see how your pricing hypothesis plays out. I say this as someone who enjoys art and owns a couple of pieces.

how the artists’ studio was this cool warehouse space that was overflowing with unsold paintings

There’s so much amazing art out there, collecting dust in studios.

It could be that people want payment plans, or that artists need better marketing tools.

My hypothesis is that a lot of art is priced significantly above what the market considers acceptable. The alternative to buying one-off art from an artist is Pier1, Target or posters.com not an art gallery. How does the typical consumer justify a X00% markup?

If artists priced their goods at a price-point that drove sales, would there be an increase in renown that would allow them to sell at higher prices later?
> Why aren't you running all your software as root?

A lot of software gets snippy when you try to run them as root. That said, the biggest advantage of non-root is protecting myself from fucking up my own system.

XKCD relevant: https://xkcd.com/1200/

If somebody gets access to my user account, they can't change my system files, but they can literally buy an entire new PC with my money, on which they can then presumably change whatever system files they want. I hope that example outlines how pointless root protection is in a modern consumer PC.
Could this turn out like HIV where there is an initial infection period followed by some dormant period and then another period where it causes more problems for the host again?
Parent is making an accounting point. Unless you have perfectly balanced trade, your balance sheet will continuously expand in either your currency, the foreign currency, or both. The Saudi government either isn’t inclined or can’t find counterparties to run enough of a trade deficit to provide the rest of the world enough riyals to satisfy their demand for Saudi oil. The USA on the other hand is willing to run such a trade deficit, it's pretty much the only game in town.

Meanwhile, the USA is able to find counterparties for its massive trade deficit because the USA itself has a huge and incredibly diversified economy and demands dollars in payment. You can buy oil from the USA in dollars for the same price you can get it from the Saudis. You can also buy all kinds of other things you can't buy from the Saudis. The dollar has massively superior optionality compared to the riyal (and most or even all other currencies) and that increases demand for it.
That would be infection fatality rate, case fatality rate is what we think it is by definition. (A case is a known case, an infection is an infection.)

Quibbles over wording aside, I think the Icelandic data showed us that the percent asymptomatic is about 50%, insufficient for boundless optimism.
What is our plan if Covid-19 doesn't go away after you recover from an infection?
Layman here. Curious: if this is true, that you don't gain long term immunity to SARS-2 by catching COVID, would that have any implications on potential vaccine in the future? Does this mean, this virus is something we cannot build a vaccine for? Does this mean even if we have an approved vaccine, it would likely have a very low probability to protect us? Or do RNA vaccines work in a way that affects our immune system that's entirely different than how immune system builds immunity against the virus itself?
Re: rwmj

I used to do taxes for extremely poor (<$10K yearly income) people in Michigan as a volunteer thing. For most of them, I could get the ~$3.5-5K earned income tax credit. A huge windfall? No, these people need that money for basic expenses like feeding their kids.

I can guarantee you these same folks—and the millions that suddenly lost their jobs—are not looking at a $1200 check and thinking, “sweet, 6 months of weed money!”.

But yeah, I’m “thinking about it wrong”.
Okay, like nothing else in our lifetimes.
Well, I don't know. A decent tablet goes for $300. I could see myself paying +33% for significantly increased battery life. On mobile devices, the screen eats most of the battery charge, therefore also contributing most to the battery's degredation over years. An e-ink tablet could potentially last much longer.
Plus many many more if they use the right compiler flags and use aligned types.

I don't think the answer is that simple. Would the initial innovation even be worth pursuing if not the existence of patents? Hard to say. At the very lease we do know that in a decade there's no more strangleholds.

The web is fantastic for websites. Facebook is much closer to a regular website than to an app. It's just content that you scroll through.

And, even so, the Facebook app has many billions of downloads. Clearly some people prefer it.

I like how this couples descriptions with actions and state. It seems like a friendlier version of Redux. One nitpick I have is the naming. I think `useBehavior` is more informative than `useTree` in the react examples. The same goes for the `node` and `tick` keywords. Maybe `behavior` and `evaluate` could be used instead?

Either way, thanks for creating and sharing!
Isn’t the concept of someone being reinfected with the exact same virus basically unheard of?
I'm always skeptical simple solutions proposed to solve complex problems. Unintended consequences or unanticipated roadblocks are often an issue.

In this case, the author might under estimate the logistics involved in getting this done. At a minimum, the author does not adequately address the logistical challenges of this endeavor in the context of already challenging testing environments. The "quick & cheap" aspect of this is therefore a claim without support.

It might be a promising line of endeavor, and we should pursue multiple parallel initiatives, but the resources needed to pursue this are highly correlated with the resources needed to perform many of the other initiatives that are also promising. There is a bottleneck. Why should this take precedence over other already promising lines of inquiry?
Good on Nina. The honor is certainly deserved and she should get credit for not only the depth of her research but also how much in terms of areas it has covered for ML. When it comes to the topic of active learning not too many other folks can talk to the depth that she can.

It is annoying to see though Dick devote the last third of the post to virtue signaling. Of course there will be less women than men winners because there are way less women in the field.

IMO things aren’t that bad. Yes restaurants and some small businesses are suffering, but look, people are cooking at home more, spending time with family, being healthier.

People don’t need cosmetics or new clothes or cars or gasoline, and some luxury flashy items take a hit because there’s no way to really flaunt your wealth inside your own home. People aren’t traveling as much, tourist hotspots that were getting trashed from so much traffic are getting a reprieve. People take joy in simple mundane things like boiling some tea or tending to some house plants instead of enduring a miserable struggle chasing their wildest ambitions fueled by what they see on social media. People who work from home or remote are no longer second class citizens, they are now first class citizens just like everyone else who is also working from home. And a result of this, I find people are more tolerable, and I even find myself caring more about the plight of homeless people, because these are the times when one really needs a home more than ever.

Not every business can survive this, but most can if they are built with the assumption that this is the new normal. That’s how you protect yourself.

Fuck man, this is a way better world, and frankly I’m not sure I really want to go back to what we used to have. I actually get depressed thinking this will all go away and I’ll never experience anything like this again in my life. I hope the pandemic lasts long enough to make some of these things permanent.
any chance you are going to make advanved level class as well? I covered basics a while ago, looking to work on efficiency
This is curious given there are well documented findings that which school you attended doesn't correlate to actual success. This is true in Engineering and Law. The problem, particularly in the US, is that the skills that are tested by the standardized tests (SAT, LSAT) are NOT the skills that make someone good at the job that comes out at the end.
Well if locking everyone up in their homes doesn't reduce cases of the ordinary flu, we really need a better understanding of how it is transmitted.

Anyway, let's agree that these numbers are worth tracking. I'm sure someone's tracking them!
Given HN's demographics, I'm probably older than most here. I've worked with and personally invented quite a few great products, usually spanning Product, UX, and Engineering work. It's a joke to pretend ageism isn't a thing, and asking questions that only a recent CS grad is going to remember is not a tacit form of filtering for age. There's not many technical questions a fairly smart, non-lazy person with some experience can't either find with a Google search, a conversation with a peer, or a bit of hacking to figure it out. It's been a LONG time since I had to write the code to invert a binary tree, but I've done stuff orders of magnitude more tricky and valuable than that countless times, as have many others. What makes a great engineer? I've lost count of how many times I've had to rewrite the code of many engineers who aced the 'whiteboard shuffle', then wrote hopelessly over-complex and unmaintainable garbage. Most of software engineering is not that hard from a 'learn the things or look them up to get stuff done' perspective. What's hard is working well with others and consistently emitting tight, semantic, legible code that's fun to look at and extend.
It also occurred during World War I. That changes the situation somewhat.
Twitter is often extremely useful for scientific fields, and in many ways is perfect for it. You can post a figure and legend, tag people that may find it interesting, and start threaded discussions. It's all in the public, with no invitations or closed doors, so it is open to discovery by that dozen or two dozen people in the world that may be interested.

Science is the ultimate long-tail of super-specialized interests with extremely small audiences, and Twitter is perfect for connecting those people with extremely esoteric interests.

There is a lot of crap, but science Twitter is also the only reason I'm on it. Sadly, my own biases against Twitter Kept me off it for 8+ years, but after I started finding the right people to follow, a whole new world opened up, and it is now a vital tool for me to navigate the literature and learn quickly which new tools are best.

But you just said that the tort scheme would do the same thing in a more inconvenient way! Surely inconvenience is not an unacceptable sacrifice.

> China, for all its failings, gets this right. Their leadership is more STEM and less lawyers and politicians.

You don't know anything about China's leadership. They're all politicians. Not a decision gets made without it being vetted ideologically -- ideology always comes first. And we should look at the timelines from China before saying they "got it right."[1]

relying on numbers from February feels sub-optimal, especially when they're entirely using numbers from one country, not many countries.
If there's a rigorous nationwide shutdown for 6 weeks, then the economy can partially open up again and people can go out more (people can still go outside now, as long as they stay away from people they don't live with - I know plenty of old people who are in self-imposed quarantine but still go on walks). This also requires the US to build up its testing and contact-tracing capabilities, so that it can keep the virus from getting out of control again.

Unfortunately, the short-sighted rush to reopen everything too quickly, or not to shut it down in the first place, is undermining these efforts. The shutdown worked in China, where it was strictly observed and enforced for several weeks. I hope the US can do the same.
SIMD is used a ton in rendering applications and starting to see more use in games too (through ISPC for example).

I'd add to the list:

- Embree: https://www.embree.org/ Open source high-performance ray tracing kernels for CPUs using SIMD.

- OpenVKL: https://www.openvkl.org/ Similar to Embree (high-performance ray tracing kernels), but for volume traversal and sampling.

- ISPC: https://ispc.github.io/ an open source compiler for a SPMD language which compiles it to efficient SIMD code

- OSPRay: http://www.ospray.org/ A large project using SIMD throughout (via ISPC) for real time ray tracing for scientific visualization and physically based rendering.

- Open Image Denoise: https://openimagedenoise.github.io/ An open-source image denoiser using SIMD (via ISPC) for some image processing and denoising.

- (my own project) ChameleonRT: https://github.com/Twinklebear/ChameleonRT has an Embree + ISPC backend, using Embree for SIMD ray traversal and ISPC for vectorizing the rest of the path tracer (shading, texture sampling).
People said the same thing after Costa Concordia. These people were never going to take a cruise in the first place.
How do we know when covid-19 entered the US? How do we know the R0? R0 is continually being estimated upward and death rate downward. We don't seem to have much clarity on any of this.

Another problem is if covid-19 was already widespread, it would have been misclassified before the huge spotlight. So, increase in cases and deaths could be misattributed.

If there is an overall increase in excess deaths, we still have a question of causality. Could the measures we are instituting themselves contribute to deaths? Just a lot of questions and lack of clarity in this matter.
Ask HN: Did Google violate their own app store policies today?
So apparently Google remote updated GBoard keyboard sometime in the last 12 hours or so.

The last time the app was updated was March 12. This morning, the keyboard layout was changed without an app update.

The Google logo, and generally very distracting text, has appeared on the space bar and the search functionality has been removed.

I'm not familiar enough with Play Store policies for app makers. Is this a violation of the terms?
Definitely! That's why I mentioned no lack of requery 2 weeks later. "Oh I was fine then, but now I feel horrible." That is missed in these studies. They're flawed!

Thanks for the info, but I already have all of this part working.

The problem is that v4l2loopback only provides a virtual _webcam_ (video source), not a virtual _screen_ - the two are different and are handled differently both by browsers (webrtc) and desktop conference apps (Slack, Teams, etc).

I guess the other issue is that conference apps treat webcam and screen capture differently; usually if someone is sharing a screen, then that feed takes over the full view for all participants so they you can actually read the content.

I don't want my screen recording only to show up in my _webcam_ view, which is usually just a tiny thumbnail.
Thanks, that is interesting. As far as I know, we are only dealing with one strain here, though there have been enough mutations that it is clear that most cases in New York came via Europe.

You seem to be talking about the possibility that they overreacted though. That's not really the point. The point is that they did nothing. They took no steps to prevent the spread of the virus.

The first, lightest, basic-fucking-step was to start screening people by body temperature at airports. Anyone with an abnormal body temperature is taken into quarantine for a few days. They had three months from November to set it up. (For reference, China almost eradicated the virus in three months from December to Feburary. And South Korea managed to almost completely halt the spread of the virus in that time). Let's look at how that went:

I couldn't find anything from December or November.

January: "Travelers at 3 U.S. airports to be screened for new, potentially deadly Chinese virus"

(https://www.washingtonpost.com/health/2020/01/17/coronavirus...)

Febuary: "CDC considering expansion of airport health screenings for novel coronavirus"

https://edition.cnn.com/2020/02/26/health/coronavirus-airpor...

March (15th): "The US administration has imposed a ban on non-Americans travelling from the 26 European countries in the Schengen free movement zone."

https://www.bbc.co.uk/news/world-us-canada-51895246

March (23rd): "Travelers shocked by barebones coronavirus screening at US airports"

https://nypost.com/2020/03/23/travelers-shocked-by-barebones...

The point is that the United States had three months of advance warning to do something. And they chose to sit on their hands and do nothing. And now 14,696 people have died, and almost 500,000 people are infected. This rate is rapidly rising. What's more, we don't even know if this data is accurate, it is very likely a lower bound given how difficult it is to obtain a test in the United States at the moment (https://www.nytimes.com/2020/03/12/us/coronavirus-testing-ch... | https://www.bbc.co.uk/news/world-us-canada-51860529 | https://www.inquirer.com/health/coronavirus/coronavirus-test...). Again, they had three months of advance warning to set this testing up, within which South Korea had almost nullified the spread of the virus.
That's not a living wage
There are plenty of blue checkmark specialists in these fields on Twitter who are ready to go to critique and contextualize their field. Of course the issue on Twitter is A) finding them B) filtering the low effort and bad faith trolling in the replies.

Other than twitter, I'm not sure where else you can find that audience that is accessible to a layman.
