I don’t think you read my comment in the context of what it was replying too. It was a response to someone saying people can get reinfected. The reports of this appears not to the case for the reasons I and others explained (false positives/negatives). I speculate it might possibly happen for real though in the case of immune compromised people who are lucky enough to survive, but due to being immune compromised do not mount a proper adaptive response. Thus develop no antibodies and and thus are able to be reinfected. Obviously that would be rare. (But so are these case reports that are driving these rumors of “reinfection” overall.)

Not really sure how you read that as somehow advocating immune compromised people do not need to take this seriously.
None of the big clouds use hardware network encryption. All of the resources in your network are at the leaves, so you might as well use their CPUs to do it. I think Google published that crypto and compression in their internal RPC stack cost them less than 1% of their global CPU resources.
IRB approval for Covid-19 home molecular test (not antibody test)
Yes good to highlight that. Most of us are on 2020.10 or 2020.12 by now.
You're right, the correct number is around 13k.
If "you" are 19 and can do this on your own, then chances are you are a CS student at Stanford, or a peer institution.
With all the memes flying around, it is tough to sort out what is believable or not. But coughing is apparently part of recognized therapy for CF - see https://www.cff.org/Life-With-CF/Treatments-and-Therapies/Ai... - so if you have fluid in your lung from covid 19, perhaps airway clearance techniques could help?
Interesting. Judging from the video, I can't tell, but does it use a height map, or true voxels? I don't see any instances of hollow spaces or overhangs, which could be done with voxels but not with a height map. A height map would give good performance and destructibility, without using a huge amount of memory. The top-down view would let you hide that from the players, such as for bridges.
"Finally admits" sounds like clickbait to me. Apple likes to innovate. They often take a burn-the-boats approach. Eventually if customer preferences don't follow Apple's lead, Apple backpedals. Microsoft is pretty much the opposite. Then they meet somewhere in the middle. I've also seen this same pattern play out with iPhone and Android (big screens, for example.)
I think both the people who say it's overblown and underblown have good points that people aren't integrating into a coherent whole.

The virus isn't that likely to kill you that you should be personally afraid of catching it, but when enough people catch it, the healthcare system will break down. And then if you have a heart attack or a car accident, you won't be able to get care either.

Somehow people just seem to feel this is all contradictory in some way so they deny one part or another. To me it all seems quite consistent.
> My school had a deal where when you signed up for an AP class you had to take the AP test. But if you pass the AP test (3 or higher) the school would reimburse you.

This just drives home the unfairness though.

You had a school that was willing to pony up this money. That is not universally true.
Why wouldn't they use Swift? Seems odd.

This is a 'mindshare' game. D had its chance, now Rust has its chance. Would have been cool though if D had caught on more back in the day. Re-invention seems to be impossible to avoid in the software world.
Reduced efficiency and inability to evacuate matter fully (which you claim) does not seem to make the method useless. Severity of the condition is likely a spectrum too.
My hometown. From what I heard, an engineer wanted to move home and started a small remote office there. I think the office is moving to Edmonton.
And the press is not in the journalism business so no one bothered to ask around. Their job is to publish the PR apparently.
The opposite is the case: we moderate HN less, not more, when YC or YC startups are involved.

In this case, though, we downweighted the story the same way we've downweighted nearly every secondary coronavirus story, for exactly the same reason: otherwise the front page would have consisted of nothing else for the last week or more.

Zoom lets people call in and it works very well.
I think I missed the bit where anyone said anything about hiring someone with a track record of failure?

A good track record maybe necessary but is clearly insufficient.

Having said that - ironically - Job himself wasn't exactly an obviously successful CEO prior to his return to Apple. He'd been fired from Apple previously, NeXT was one of many workstation manufactures and less successful than many direct competitors (eg Silicon Graphics).

Eric Schmidt is another example. Prior to Google he was CEO at Novell where (quoting Wikipedia): "He presided over a period of decline at Novell where its IPX protocol was being replaced by open TCP/IP products, while at the same time Microsoft was shipping free TCP/IP stacks in Windows 95, making Novell much less profitable."
Yes I think you know this but you made it sound pretty scary. For anyone reading, the car drives as normal, can still smoke pretty much any... let's not mention brands here, but suffice it to say, there's nothing to prove, and everything continues to work just fine. The UI comes back in a few seconds.
Swift’s performance isn’t really up for high-performance network processing, at least not yet.
The obvious answer is to test aggressively and quarantine the infected and direct contacts. Then the rest can be out and about.
Airbnb was for people to make extra cash with extra space. I highly doubt people are going to be in ruin over a couple months of cancellations.
> If the money is being put to R&D or even just enabling the company to scale manufacturing, I'm pretty okay with that.

That makes sense. On the other hand, the government has deep pockets. They could buy the company, fund the R&D, and still keep the prices accessible.

In pandemics, this is what we want and need.

I’m also alive to all the ways in which these powers could lead to corruption and overreach in ordinary times. I oppose the Patriot Act and abhor the wars and states-of-emergency without-end. But I’m given to believe we are not in ordinary times.
The Chinese government told the World Health Organization on Dec 31, 2019. The WHO notified the rest of the world on Jan 1, that includes the US. SO Trump was correct.

The kits were not available thanks to how the FDA works and the stringent processes put in place. Could it have been faster? Sure. The lab-developed tests were found to have errors. That had to be corrected and reshipped. That's hardly "foot dragging".

Make sure to read the "Criticism" section of the article before you read any other parts.

This test is bad, and there are other tests that are better.
I'm surprised by how frequently I encounter people who are familiar with the test, but not of the fact that it is far from even an attempt at good science.
I'm not insinuating that YC moderation is at fault here. Unfortunately, there are plenty of others who'd be incentivized to flag an article in such a coordinated manner.
My approach is to use code generation tool to handle the typing and API (server side routing and client side SDK) in one-step.

DB side is not handled by the tool because that's a blackbox the client don't need to know.
Yesterday I did a Discord voice hangout with the folks I normally co-work with. It went off pretty well, I got to hike outside while talking to them.

It does have its limits, though. Everyone's voices get filtered through the system with the usual dropouts, zombie connections, feedback issues and equipment variations making it so that some people are heard more clearly than others.

But as a measure for connecting without physical presence it's a godsend, and a group chat can be less structured than a meeting or phone call. Set a rough starting time, let people hang out in the room, and things happen. Not the same things that happen in person, but it's enough.
Agreed. I don't know how software-based middle-man companies like Airbnb and Uber don't become insanely profitable. I'm sure we're both missing some complexities, but one would think you'd build the initial feature set and then basically be kind of done; is the rest not essentially just some UI/UX tweaks and engagement optimization over time?

As far as I can tell, the functionality offered by Airbnb and Uber hasn't changed at all since they launched over a decade ago. The only things I've noticed them add are "Airbnb Plus" and "Uber Black", which are just "pay some more for a nicer/better-looking place/car".

Of course building these apps to work as smoothly and engagement-y as possible isn't easy, and I'm sure I sound incredibly naive to many people who've worked at those companies, but my assumption would be that there'd be a lot of upfront investment and work building your one product with its one feature - connecting seekers and providers and offloading all the meatspace work to the providers (and phone manufacturers, for ridesharing) while you take a cut - and then your revenue and profit should just go up and up over time on its own.

Why isn't that what happens? I'm sure one obvious answer would be "wasteful spending and unnecessary hiring", but I have no idea if that's actually the explanation here for either company.
czzr shared this insightful article which makes roughly the same point, but much better:

There was a part that mentioned how one of the soldiers identifies with the child protestors, and how a high ranking officer mentioned if he were a Palestinian he’d be a terrorist. I don’t think it matters, they are basically just doing their job (or playing the game) they’ve been trained for. They still have to ask for authorization from the chain of command, so it doesn’t really matter what they think.

Pretty heavy article
My guess is because every time there's an article on them, the comments ar unrelated complaints about some bad experience they had with Airbnb 3 years ago.

We are now offering Guests full refunds and Hosts no-charge cancellations for reservations booked on or before March 14th with a check-in date of April 14th or earlier.

Well, that's just swell. First of all, this won't be over by April 14th, for example https://www.minneapolis.org/minneapolis-convention-center/co... "Events at the MCC will be restricted through May 10, 2020." second if you have a longer trip which got cancelled because originally it was scheduled to start before April 14th then all your bookings are toast.

I had zero problems cancelling my hotels.com reservation at Dorval though.

My gosh, your response is simply asinine. You think that all members of Congress and the Executive branch don't give a fuck about the health of people and just care about making more money.

I believe the implicit assumption here is distrust in reliability of supply, other people’s behavior and infrastructure in general. Some cultures are more resistant to this kind of stuff.
There have been a lot of Airbnb threads, often negative, on HN's front page: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu....

Perceptions like this are usually sample bias, since we weight the things we notice more heavily, and what we notice is conditioned by our pre-existing opinions.
The Tesla dashboard should be predominantly a real time system. (It appears not to be.)

Different features of the dashboard should be implemented as different services, ideally on different processors or different virtual processors. They should have fixed time sliced allocation. Limit the impact of one process interacting with another.

The different processes should all send and receive visual/touch IO to a master display server. The master display server should be a hard real time system.

I think we all know this is really how it should be done, it's just comical that Tesla says NO! and does it their own unsafe way.

They don't treat the dashboard as safety critical. Despite that is where all essential warnings show up, in addition to the speedometer. You can easily lose access to all those while driving. I have multiple times witnessed the dashboard reboot for a few minutes while driving.

I think the long term outcome is that Tesla mostly gets away with this, other car manufacturers attempt to copy their system with extremely poor results, dangerous failures result, and regulations are created.

Throughout history, the propaganda of victimhood has always been used to perpetuate horrors. Whether it is the nazis, whether it is the israelis/zionists, whether it is the american settlers, etc.

Almost always, victimhood is the justification of theft, attacks and brutality. What was the nazis justification for brutalizing jews and stealing their property in europe? The economic crisis post ww1. What is the israelis justification for brutalizing palestinians and stealing their land, the holocaust. What was our justification for extermination and stealing native land? Native massacres of settlers.

If you look at history, every oppressor claims to be the oppressed and uses it as justification to oppress. Doesn't matter if it is a democracy, monarchy, communist, fascist, etc. They all cry out "Ow" in pain as they smash another person in the face.
A running joke in the CF community is "Excuse me. It's time to go beat my (spouse/child)."

Manually palpating the chest to loosen phlegm to help people with CF cough it up is also a standard treatment for the condition.

Airbnb is known to be approaching the 10 year deadline on ISOs, which they were hoping to clear through a 2020 IPO. Hopefully they come up with a creative solution with their legal team to ameliorate this.
> If your language uses strict evaluation (like most languages), it probably makes sense to use a left fold on lists.

The standard libraries of strict languages agree. Python's `functools.reduce` and JavaScript's `Array.prototype.reduce` perform strict left folds equivalent to Haskell's `foldl'`.

Interestingly, JavaScript also has `Array.prototype.reduceRight`, but it's not equivalent to a `foldr`. It processes the list from right-to-left, so is approximately equivalent to `reverse` followed by `foldl'`.
That definitely wasn't the case with that submission.

Airbnb threads, by the way, invariably turn into the same generic debate about Airbnb that some people seem to want to have over and over again: "I had a bad experience" vs. "I had a good experience". (Variations: "Airbnb ruined my neighborhood." "They rented the place next door to noisy people." And so on.) Just look at the comments in this thread.

HN moderators are trained to downweight such repetition, because it doesn't serve curiosity, which is what this site exists for. For some reason, Airbnb is one of the topics that people (or rather, commenters inclined to post in such threads) seem unable to bring curiosity to.
If performance is a concern a MATERIALIZED VIEW might be a good tool to use - I've worked in similar sounding legacy environments and usually, while the underlying structures are immutable due to layers of code, adding a mat view or two on top is do-able.

Maybe that'd be some help?

To spell things out a bit more:
A list is fundamentally constructed from [] and :. In the sense that a list is either empty [] or a head : tail, where tail is another list.

One might write 1:2:3:4:[].

foldr is deciding where to map [] and :. So for example:

[] => 0
: => +

Turns the above list into 1+2+3+4+0.

With that understanding, foldr (:) [] becomes:

[] => []
: => :

which is fairly clearly the identity.

The USA is very unusual in the developed world in having armed police. In Germany, for example, the officers on the streets do not carry firearms. What they do have is riot squads a couple minutes away if force is actually necessary.

I hear arguments like this in the USA a lot, but it doesn't seem to be a major issue in the rest of the world. I suspect it's another talking point that assumes certain conditions as universal that are very unusual and strange.

Ask HN: Whats the best way to crowdfund supporting local hospitals?
The idea is to run a fundraising campaigns to support the staff of local hospitals with gift cards and catering from local businesses that are also suffering. Are there any good platforms that could help?
Cars get eligibility for updates depending on when they were purchased, what hardware they have (including incremental revs that happen with newer versions of a model), what features they have that relate to the update, whether they have purchased the (future) full self driving add on, whether they are in the Early Access Program, and whether the customer has complained to service about a related issue that the update covers... those are the ones I know about.

On top of this (or maybe under it) they have a layer with rollout tiers for Tesla owned cars, cars of employees who opt in for early updates, and customer cars. Probably more than just this. And then with all that they roll it out over time, so we're not all getting the update the same hour, but generally it starts with a trickle the first week and then becomes a flood of users getting a given update over the course of the following week or two.

If you're not on WiFi you might get the "Update Available" notice in the UI first, and then when you get to WiFi it downloads it. But it doesn't wait, if you don't see that notice and it has WiFi, it just downloads it.

Also Tesla says that if conditions warrant, it will download the update even when there is no WiFi. But I think it waits a while to try to opportunistically get on WiFi if it can, to reduce load on the LTE network it uses. If your car never connects to WiFi (which is up to you to do) then it will download, if it can, over LTE if the update is high enough priority.

There are probably silent updates as well as another commenter indicated. Don't know about those but it makes sense.

A lot of the beds are used for routine scheduled stuff that can be postponed. While the ER/ICU/telemetry capacity is much smaller (can’t find online source but it’s about 150 beds in Stanford), these are usually reserved for postop and ER flow (car accidents, etc.). Plus there are expansion possibilities. Overall, there about 500-1000 beds for critical care in Santa Clara that can be made available (I also suspect there are not that many car accidents, broken legs, etc right now). Overall, we are at about 10x in available capacity right now.
