This is great. There is a lot of work being done to figure out how much undersampling you can do on a typical MRI and reconstruct a good image. For typical scanners, this gets you faster scan times. It will be interesting to see how much those techniques translate into taking a super low-powered MRI and allow it to yield decent images.

Whether or not such techniques are good for accurately detecting lesions seems to still be a bit of an open question. (It's less relevant to my particular research interests for now, but obviously extremely important for clinical use.)

A lot of the fallout from over-imaging (especially when, like MRI, there is no ionizing radiation so the test itself isn't harmful) is due to physician behavior and standards of care. But those behaviors and standards can change over time.

A bit tangential, but I suspect that at some point, we will think it anachronistic that cardiologists tried to visualize the heart's function by listening to its sounds with their ears.

I feel like Zuckerberg doesn't get enough credit. I never heard anyone describe Facebook that way, but immediately when I read "something between a telco and a newspaper" I felt like "oh yeah, that makes sense." They clearly offer services that are very telecom-like, and others that are more newspaper-like. They probably also have planned out how being viewed this way would effect them favorably, but it also just makes sense.
I honestly didn’t find anything of interest in this post. If you already know that rust / fp in general tend to have safe and sound type systems which enable developers to encode complex relationships in the type system to prevent race conditions and catch memory leaks at compile time then there is not much for you here. I suspect a lot of HNers who would be interested in this post already know that.
The word “casualty” has been used since at least the 17th century to mean a person killed by an accident, mishap, or disaster. They do not have to be a soldier or something. For example, try a Google search for “earthquake casualty”.

Unfortunately, the doctors told him it was a (rare) treatable form of cancer that needed to be surgically treated immediately, he refused, preferred to treat with diet, didn't work, finally had to have a more much invasive surgical intervention (transplant). Helped, but he still died. If he would treated it correctly when he was first informed, he would probably still be alive.

In the US it isn't the poor that suffer but the lower-middle class, who are neither poor enough to get excellent health care for free nor wealthy enough to have high-quality private insurance.

The policy problem is that to adequately cover the lower-middle class you would need to substantially raise taxes on the upper-middle class, which pay anomalously low tax rates in the developed world. And the upper-middle class in the US quite enjoys their low tax rates. (While often focused on, the upper class often pays aggregate tax rates in places like California and New York that are more in line with Europe.)

I mean it makes sense. We already know Forsythia is safe-ish to eat, has antiviral properties, and it's probably growing within a couple blocks of wherever you live. If it works for COVID-19 then that's kind of the ideal scenario. ~80% of people recover on their own, so a treatment doesn't even need to work that well if it's something that's safe enough for people to just start taking as soon as they get symptoms but before they're sick enough to warrant seeing a doctor, if at that point it can actually make a difference in clinical outcomes.

Something that slows down viral growth by 10% isn't going to do anything if you start taking it a week after you get sick, but if you start taking it at t=0 it could make an enormous difference.

I am starting think it is the money that strips all of the fun out of it. Most software developers are not developing for fun these days.

Not sure this view relates to any of the actual literature on negotiations outside of NVC (which is a cult), or any significant experience in negotiations. It is quite patronizing though. The game of putting a lack of virtuousness on others and transferring responsibility to others for the tone is not negotiation. I think psychologists call it gaslighting.

Telling the person you're negotiating with that they are just being confrontational is simple passive aggression.

> The sheer scale of social networks makes the effect fundamentally unlike prior scenarios.

Is this even true? There are a billion people on Facebook, but it's not like a given post ever gets seen by more than a small fraction of them. Nearly the entire human race has been reachable by postal mail for over a hundred years; the size of the network really has nothing to do with anything.

What has changed isn't the size of the network, it's the culture. The CDC and a thousand independent doctors say that vaccines don't cause autism, but too many people don't believe them over the mother of a kid who both has autism and was vaccinated, even if that mother has no real evidence that one caused the other.

The problem there isn't that someone is saying something which is wrong, it's that other people are too credulous of unverified claims. Nobody should believe outrageous claims from some random stranger with no domain knowledge and who is contradicted by multiple domain experts, unless they're stricken with enough curiosity to actually replicate the experiment themselves. And even then they shouldn't believe based on the word of the stranger but rather their own observations or those of someone they themselves find trustworthy.

The solution isn't censorship, it's to teach people how to properly evaluate evidence instead of being credulous and easily manipulated fools.
> Would you be happy if right now someone forced you to go to bed at arbitrary times

the issue is of course, and that's what children don't realise, that seemingly arbitrary rules exist for good reason. In this particluar case it's because children are not able to delay immediate gratification. And I, as an adult, am in fact still constantly obligated to participate in farely arbitrary rituals, at work or otherwise.

>Are you calling them immature, youthful, or something else?

I'm saying they often exist in an environment that is very isolated from larger obligations to a community. The hacker and tech CEO as a middle aged man in a hoodie, often obsessed with youth and in a sort of state of permanent teenage rebellion, persists for a reason.

> that consider abstract concepts such as society and morality as more important than the personal freedoms of a human

society is not an abstract concept, the need for cooperation, order, safety, is present in every decision every day. It's individual freedom that is an abstract concept. In the case of cyber-libertarianism that is prominent in the tech world it's arguably not even 30 years old, and it only functions within a severely restricted space, both physically (say in the valley) or digitally (in some corner of the internet).

>What is this supposed to mean in the context of the internet?

it means that, if the public internet is supposed to be a healthy space, individuals who harm the well being of the larger community need to be able to be held accountable for their anti-social behaviour.

>Which goes back to the point about lgbt rights.

it's true that communities and social cohesion can sometimes unjustly punish people, however well functioning systems are capable of reform, and this is no reason to abolish social order altogether. To put it another way, do you think that within the LGBT community, laws against hate speech on online platforms are popular or not popular? Marginalised groups in particular see the value in collectively maintaining order, they least of all are going to believe in mythical individualism.

I'm not sure what Google should do, but someone else made a good point that I think applies here: 'Google says X' probably has much greater propaganda value than 'this local company that is clearly under our government's authority says X'.

The lack of an enthusiast tier between Free and $10/month has kept me from being a customer. For years they have been trying to add value add features, with some of the forced changes making the platform less attractive to me. The features have really been geared around justifying business site license, not 'prosumer' usage.

The recent change of the free tier so that it no longer allows me to pair all of my devices was the last straw, and I've moved off their service.

Organized crime in Sweden likes grenades and some similar explosives, largely because they - by accident - was legal to import a couple years back.

Grenades became much easier to get ahold of than handguns, which have had some weird effects, as they seem to have come to be used as intimidation between rivals.

The use has been dropping the last few years, and should hopefully be back to the pre "legalization" levels soon.

It's all certainly quite unfortunate, but the number of casualties are perplexingly low. It really seems that whomever it is that does these bomb/grenade attacks go out of their way to avoid people getting killed. Not that I understand why exactly, except that it seems to be about intimidation in the majority of cases.

Hi all,

Waterfox dev here. I’d appreciate if people read the blog announcement here as well:

https://www.waterfox.net/blog/waterfox-has-joined-system1

While I’ve always kept Waterfox privacy friendly (and it will remain so) I’ve never tried to have it as a privacy product specifically (that was cherry picked by the author), as I’ve explained in the blog. It’s not something I’ve wanted to go down, so all the outrage towards me for that has been, at least towards me, a little unfair.

Also, this post has led to a lot of (what feels like) harassment from disgruntled privacy users, even though nothing has changed.

System1 are pivoting to focus on more privacy-focused ventures, something I’m sure a lot of HN readers are familiar with.

At the end of the day, they were the right fit and aren’t going to change Waterfox in any of its privacy aspects, and I can finally grow out Waterfox to hopefully be more than it currently is.

What should be IMO a joyful occasion for myself and Waterfox users has ended up into a collection of conspiracy theories and rather unkind words.

Regardless, I hope everyone has a good weekend and am more than happy to try and answer questions :-)
It's not so much how often it happens, but how freaking hard it is to find the problem by inspection when it does happen.

I'm not sure if this advice applies to founders.

As a founder, I was always extremely motivated, to the point it was painful to take a break. I required heavy discipline to slow down. At the point many founders lose motivation, they have likely been working too hard.

I feel like this in conjunction with highly configurable voice navigation would be great. I'd opt for a scenic route or a dirt road given some time trade off. In addition to that I am so sick of Google maps giving me four instructions each time I merge onto a new freeway (2 mile warning, immediately before, merge onto, continue on). Maybe even an assistant that can tell you the options and let you choose, and that understands when you say shut up about exit 217.
Sorry if I was phrasing incorrectly. System1 are a search syndicator and that’s how they’ll be pushing forward with it. A lot of people seem to have extrapolated more than what’s actually happened.
There were a few breaking change epics in MacOS history.

There were three major breaking changes for MacOS.

- If you bought the x86 version of software in 2006. It would potentially work until 2019 when Apple dropped 32 support.

- If you bought the first first version of OS X PPC software in 2001, it could potentially run until July 2011 with the release of 10.7.

- If you bought a classic MacOS app, it could run from pessimistically from 1992 with the release of System 7 to 2006 with the introduction of the first x86 Macs.

Is the value proposition here the CSS performance benefits of shadow DOM without needing shadow DOM? If so, its surprising there's no direct comparison in the link.

I could actually see this being pretty compelling for easy performance wins. Its much easier to adopt a single CSS property versus a different model for DOM interaction. The churn in the spec and various implementations didn't help shadow DOM adoption at all.

Its 2020 and I've been using shadow DOM(plus web components) for 6 years in side projects. When the stack has native support its great; it runs fast and is a pleasure to develop. The downside is you have to be willing to swallow polyfills that degrade performance when you don't have native support.

If 2020 isn't the year of shadow DOM, maybe 2022 can be the year of shadow DOM polyfills that don't ruin performance.
That’s just how the Mozilla platform works for newer products (that Waterfox has inherited).
Probably just bad phrasing on my part. Also, Waterfox is OSS? There are definitely some security patches that have been released that I’d recommend you have; so for your sake at least use an up-to-date browser.
People who read about negotiation typically learn it's a positive sum process for creating and discovering value. People who have not often conflate haggling with negotiation. There is a critical theory that arbitrarily paints the process as "transactional," or "confrontational," but it is not something that survives and bears out in a competitive environment.

The managers I have seen who subscribe to the co-operation model tend to passively ride billions in valuation into the ground. The ones at successful companies are merely survivor bias from riding growth.
Is he wrong?

Like a telco, Facebook allows people to communicate with one another without going through another intermediary. However, it's not one-to-one like your phone, it's one-to-many.

Like a newspaper the messages are broadcast out to everyone that's subscribed to receive them. However, there's limited editorial control by Facebook (except for content breaching their policies).

If we thought of Facebook as a glorified listserv with a pretty UI (and a bunch of tracking cookies and injected ads) would it still seem like it should be treated as a publisher?

I'm not a big believer in collective guilt.

If someone hangs out and shitposts on a marginal forum, what is the responsibility of the other people on that forum for their criminal actions? If they're co-conspirators, that's one thing, but making shitty memes and shooting up a synagogue are very different things.

I've noticed that every single one of the recent mass murderers from the white supremacist camp has a Facebook account, but no one seems to want to shut down Facebook, just 8chan or whatever.

You mentioned truck attacks; someone recently drove a van through a tent full of people canvassing for Trump in Florida. Do we deplatform wherever he was hanging out online, or is it just the combination of "did a terrible thing" and "has opinions that we don't like" that justifies censorship?

I don't know what the line is, exactly, only that a lot of people are really eager to draw it way before the point I'm prepared to.
Left Dropbox this week after many years. I've got storage with iCloud and Google Drive now, which are cheaper combined and provide a lot of other services.

It felt like price increases were to pay for new features like Paper, which is not what I ever wanted from their service. I'll keep an account on the free plan, since many services have Dropbox integrations.
> Another study — a 300-person controlled trial — will test serum from COVID-19 survivors. The bare-bones strategy, based on the idea that the antibodies one person steadily builds up to fight a virus can rapidly help someone freshly infected to fight it off, has had modest success when used to treat other viruses in decades past

I’m surprised we don’t see this type of treatment more often. It might be worth it to set up infrastructure to do this type of treatment at scale everywhere, since it presumably works in most recoverable viral infections.

That's true, but I suspect the aspects that math can't model are either known to be intractable problems (e.g. modelling turbulence, Navier-Stokes), or otherwise have been delegated to other fields like philosophy or the humanities.

So I don't think there are physical aspects of reality that we are missing out on because they cannot be modeled using math.

However, the social and historical aspect of science is undoubtedly incredibly important, as well as the selection of the scope of science. These aspects of reality might be underrepresented.

To be more concrete, perhaps in 50 years we'll have doctors who specialize in "suburban salaryman kidneys," because the scope of study will expand from just the internal organs, to the internal organs, together with the external environment and social conditions.

We're already sorta there. A physiologist would conduct research on specific organs and systems, while a general practitioner/family medicine doctor takes your history (i.e. considers the social and historical conditions that lead to illness)
> That is too bad, everyone has their price though so not unexpected.

I think that’s a little unfair, makes it sounds as if there is malicious intent. I was just thinking of a way I could grow Waterfox with a company that would understand what Waterfox needs. VC for example would’ve definitely been the wrong fit, as they’d want an exit strategy and want it fast.
> The IIgs had ADB before the Mac

Marginally. The IIgs was released in September 1986; the Macintosh SE and II (which were the first Macs to support ADB) came out in March 1987.

The 65C816 eventually made it up to 14 MHz, but I'm not sure those speed ratings were available in 1986. Even when they did, integrating them into the IIgs took some significant effort by accelerator manufacturers.

> if Apple released an 8MHz IIgs it would have compared very well against the Mac. Woz is even quoted as saying that.

Perhaps against an 8 MHz 68000 -- even then, the 16-bit data bus, 32-bit registers, and hardware multiply/divide on the 68000 would have made it stiff competition for the 65C816, which still used an 8-bit data bus, 16-bit registers, and supported no arithmetic operations more complex than addition, subtraction, and comparison. Against the later 680x0 parts, there'd have been no contest.
