That doesn't mean that misleading the public about the effectiveness of masks in the early pandemic was the right way to go about it. The CDC came out and said that masks wouldn't protect the wearer.

I also saw blog posts from people in public health departments at respectable universities about how masks on laymen have no effect because we can't wear them right/will touch our face too much to adjust them. Whether they believed that at the time is unclear to me, but that was the theory being pushed by a bunch of experts to explain the CDC guidance.

I think we were overestimating the transmission risk from surfaces/face touching at that time. I also think we underestimated the effectiveness of basic cloth masks thinking that only filters would be useful. COVID is more likely to spread via larger droplets than some other viruses. However a closer look at literature from Asia on the previous SARS pandemic should have suggested that masks are more likely than not worth promoting.

So I have to wonder if they considered what would happen if/when they had to flip the story once masks became more available. I doubt they expected it to become such a critical part of the pandemic response, otherwise they probably would have been more careful with messaging. Of course these decisions were made under a lot of pressure with not much time to strategize - I just hope they learn from this and reconsider a bit how they communicate. Because I do think this exacerbated the anti-mask issue. IMO they could have even avoided Trump making it political if one of the day 0 rallying cries was to ramp up mask production.
That’s what air tags are for! Shocked they didn’t put that tech into the remote.

I think that must be how you configure it? The too banner does not show that for me - it grabs the shows I e been watching from infuse tv and. Puts them there
I live in the US and saw a BitCoin ATM in a gas station just the other day. I asked the cashier about it and apparently they take BC payments too.

So, at least where I live, you can "buy stuff" with BC.
If anything, this whole case underscores the fact that Engineering and Computer Science schools/colleges need to be teaching ethics as a core part of their curriculum.

It is appalling to my partner, a phd in bio research, that even as undergrads we didn't have at least a couple of courses covering what ethics was, how it informs, and how it applies to everything we do.

Worst of all, because of this lack of education, many big tech firms have done unethical experimentation on us unsuspecting users, simply because the developers never questioned if they should do it.
I have zero weirdness at all. It just works perfectly all the time.

Neither monitor supports Thunderbolt. But I run off of a USB-C to Display Port cable and one is using the HDMI port. Both run at 60Hz as it is HDMI 2.
Ah. I hadn't considered credit card churning. Thanks!

(I do have some reservations -- I'm guessing that only a small minority of cardholders attempt to churn their balance from card to card or pay it off before the end of the promotional period. 12-month lines of credit don't come for free, and if the expected average payoff wasn't worth it, credit card companies would probably stop running these promotions.)
Ask HN: How would you code a Webserver like Nginx?
Loaded question, I know. I am fascinated with how web servers work and wondering if you all can share some resources on how to write your own web server. I google a bunch. I am interested in using Golang ideally (fun project for now). I want to build it in such a way that I can add my own rules like nginx and not have nginx at all as a proxy.

So, any ideas/tips/resources on how one would go about writing a web server in Go ? The hello world examples are a good start but how do you parse URLs etc ?

I think it's debatable whether that's a necessary condition for something to be reasonably considered a machine.
Another key detail is that the experiment was carried out without having been submitted to or reviewed by the IRB.
Back in the day I did use EC2, but to get the same performance (especially SSD IOPs) it cost a lot more than DigitalOcean. Back then, the monthly bill for EC2 was over $3,000/mo. Switching to DigitalOcean we got better performance for under $1k/mo.
You'll be waiting on that gas station for hours for the payment to go through.
> As long as the labor costs as tenfold of a Chinese company, any attempts of this will fail.

Why? China isn't dominating the chip-making industry, but if it were only about labor costs, they probably would. That's a hole in your theory.

Also creating conditions were things like higher labor costs prevent strategic industries from being located in your territory is a political decision, and political decisions can be changed.
I'm very curious what gas blend were you using at 300 ft - I'm fairly sure that would be fatal on air or even nitrox.

I'm also shocked that you could come up from that depth with any sort of urgency and not be seriously injured / killed by some form of DCS.

Maybe I misunderstood and you were not a beginner, because otherwise that tour operator has no business running a dive op.

I don't know if you're being serious but, given the lack of improvements in chip design lately, that would indeed be impressive.

That's because cryptocurrencies are typically much better than conventional currencies for speculation and crime. Some "coins" are also usable as standard payment methods, but they're either on-par with conventional banking or just slightly better, not enough to make them the preferred choice for mundane transactions. The stigma also doesn't help.
The site seems down. Archive.org backup: https://web.archive.org/web/20210427143048/https://openfligh...
Your argument ignores whether or not the technology makes the crime significantly more likely.

Technology comes with negative externalities.

The cryptocurrency world needs to accept that it does have negative externalities, and show that the benefits outweigh them, rather than pretending that they don't exist.
I do agree. But what I am trying to say is that we should be pushing for 6K and 8K ultra wide monitors rather than the old hack of 2 monitors to one computer.
Speculation is a huge use case. Bitcoin will never be practical for day to day transactions but it may be for a settlement layer - certainly Ethereum is proving that out right now. A few minute settlement time is a huge advantage over what clearing houses offer. The immutability of the block chain somewhat less so, but if you introduce third party trust and can settle things off chain in case of a dispute, well, I for once do see a practical use of crypto beyond black market transactions and speculation.
Hey thanks. I have kids and talk to them openly about the problems with the Cape, and how they might find more opportunity elsewhere. Like most kids they love their home, but fully recognize that housing costs, and career opportunities are limited.

My wife and I built our business from the ground up, but couldn't have done so without family support and some advantages that others do not have. This privilege is something we recognize and work to "fix" by participating in local government and biz development organizations.

Getting "young" working families to simply show up at town hall is a huge challenge but we're working on it, and are not going to let the Cape slide into just a place for the wealthy, elderly and second home-owners.
That’s an excellent idea. Debuggers certainly need better documentation, and guided tours are a good way to teach skills.

Some of the Mozilla folks did livestreams of their development work on Firefox, including debugging sessions. I haven’t watched any lately, but you might search them out. If they kept it up then they might be using RR now, instead of just GDB.

Here’s a demo video for Pernosco: https://robert.ocallahan.org/2019/10/pernosco-demo-video.htm...

Pernosco is based on RR, but this probably won’t teach you anything about using RR, since the UI is so different. But it was a memorable one because Brendan Gregg produced a really good tutorial for GDB, where he debugged a real problem in a real program (instead of a made–up problem in a program written just to have a made–up problem inserted into it). The Pernosco demo debugs the same problem in the same program, so comparing the two can be quite easy. I would like to see someone the same type of tutorial for RR, and for other debuggers that people like.
Woods Hole isn't like most of the cape, though. It's got a different culture, it's geographically very much on the edge of it, the landscape is super different than the gentle beaches you get on most of the cape, pretty close to Boston relative to other spots, etc. I would agree that many parts of the cape fit your critique though.
Rust as well, and the intrinsics are identically named so your tutorial is good for rust as well.
Maryam Mirzakhani drew her way to mathematical greatness (2017)
This excuse doesn't make any sense. Their messaging at the time was "masks aren't effective, plus we need them for healthcare workers to care for pandemic patients". If they're not effective, why would healthcare workers need them? Higher viral loads put you at higher risk, but the messaging decidedly wasn't that masks are only protective at high viral loads. Let alone the incredibly basic prior on respiratory diseases' vector being limited by _covering up the sources of spread_.

The initial recommendation, the flip-flop, and attempts to explain it away have been universally incoherent, because the real reason is that the CDC and FDA combine the worst of the federal government's bureaucratic inefficiency with medical culture's innumeracy and blind status quo bias.

Leaving aside the failures of pandemic preparedness stretching back multiple administrations (the PPE stockpile had been depleted since 2013, and I don't need to describe the trump admin's failures..), it would have been trivial to do what we eventually did, and what many other countries did: recommend face coverings of any sort, and encourage people to save n95s for medical personnel. The insane route we ended up taking had people hoarding n95s anyway and deeply poisoned the well of trust in public health authorities in general and masks in particular (helped along by our president).
Not true at all. M1 and follow-ups are about single thread performance, the only actual performance most consumers are likely to notice.
I have an Acer Predator that has this issue (Whether using my Mac or PC attached.) Power cycling the monitor makes it go away. Basically the left side of the screen is shifted one pixel higher than the right side of the screen, making a vertical line down the middle where the shift changes.
1 - Apple is not going to enter the server market ever again, especially not the generalist cloud infrastructure

I hope 3D printing homes will take off now that lumber prices are so ridiculous. The sudden cost increases in other materials will now hopefully give 3d printing space to achieve economies of scale.

Imagine homes that are printed with a 20 year life expectancy. Especially in America where I don't know many families that remain in the same house for 20 years. We could start going to the Japanese model of razing the house as an expected part of the land purchase. This has the added benefit of making it significantly easier to keep houses up to modern code.
These are a bit random. The church has many perceptions similar to this one.
I'm not sure about that, because the M1 cores are, in essence, quite old at this point; they're pretty similar to the A12 cores. Apple usually does quite a major micro arch refresh every few years; it's probably coming up to time.
SaaS Growth Hacking – 5 Quick Tips
Point is, saying "Samsung has that feature" is like saying "Tesla has L5 self-driving next month". Just because a company says something doesn't make it true, and other companies are not required to try and compete with snake oil. Apple's ability to execute has little to do with it.

> Changing code that you don't understand because you "found" the bug with a step through debugger is a recipe for disaster.

I don't get your point, because that's not what I suggested someone should do. I think (on rereading my original comment) my point was the exact opposite: Develop an understanding of the code through the effective use of a debugger:

> In fact, the debugger can be a fantastic way to learn the code since the dynamic behavior of a system can often be hard to infer from its static representation (looking at you WPF and XAML, or any project where architecture astronauts went hog wild with certain design patterns).

You seem to have inferred something from my comment that I did not say.

Sure. I'm not arguing using a debugger if that is what you prefer. I'm saying that to have no clue where in your code base an issue is cropping up, like _0_ idea, says to me one should spend some time understanding the code before any type of debugging.

As a German, I have to say he's very well proving the Article's point by resorting to whataboutism.

Nobody asked about country X but when criticized we answer with the shortcomings of country X.

I disagree with the world-classiness. I have rarely encountered less ambitious institutions.

But its indicative to me that we claim a wonderful education system in lieu with social cohesiveness, yet it is our very education system which makes us one of the least socially mobile industrial nations on earth.

What I'm getting at is this: The story is about notable consequences at a school, which is not a private institution (generally). So, the commenter was probably using the term in conjunction with such consequences. It was clear from the comment, and the response seemed to be nit-picking a pseudo dictionary definition, so I tried to point out the colloquial usage.
We actually do have a lot of manufacturing in the EU; maybe not cheap plastic gizmos that you find at the store, but we have a relatively rich automotive industry which reaches into aerospace engineering and agriculture.
Just like masses being overscared with sharks because of Jaws, its probably because another but much less popular movie “The Depth [1977]” with Nick Noltie where in a final scene Noltie wins underwater battle because he knows where huge Murena lives and put a villain head in there. Then we see that Murena litterally sicking him into her hole with a force that break his mask and break him in half. Definitely one of the most memorable scenes of the movie and definitely what made me start my doving adventure (now cerified with CMAS and PAID up to deep dive / rescue diver). Definitiely movie worth rewatching.
That image is of GP's heart rate, not heart rate variability.
HRV is not a measure of change in your resting heart rate over time, its a measure of the difference on a per beat basis. Even if your BPM is 60, your heart doesn't beat exactly once a second, it will actually vary in length by some number of milliseconds back and forth. This is what is measured when talking about HRV.

It is believed to occur as the parasympathetic and sympathetic nervous system "fight" over raising and lowering the heartrate. The symbiosis between them lands on a steady rate per minute with fluctuations on a per beat basis.

Sure there's a lot to be learned.

Even something as basic as having a national stockpile again, learning that we should have a decent manufacturing base for these kinds of critical items, and all the lessons about how to communicate with the public regarding health recommendations. There's plenty to be learned.
Heart rate variability really does not mean variability in heart rate (such as is shown on the graph linked) it is more at the 50-100ms level in change in timing between hear beats. The graph does seem to show a reduction in RHR but does not address HRV (as I understand it)

My private conspiracy theory (supported by nothing) is that Intel promised to Apple good 10w processors back in 2014-ish, and Apple designed 2016 MBP based on that promise. And when Intel didn't delivered, they shipped Macs anyway, and either started working on M1 or cleared any doubt about should they continue working on it.

The result I would predict and hope for in a few years would be better chips from everyone in the market.
