A load of people in this thread are saying the CDC (and others) are lying about masks.

For members of the public walking around a mask provides at best marginal benefit, and that's only if the wearer complies with a strict regime of donning and doffing protocols, and if it's combined with a full set of other PPE (disposable gowns, gloves, eye shields) and frequent handwashing.

As soon as you drop any of those you're not just making the mask a bit less effective, you're probably increasing the risk over not wearing a mask at all.

There are a few routes of transmission -

fecal oral; fomites to hand and then to eyes, nose, or mouth; and droplets landing on your eyes or being breathed in.

It's likely that in members of the public the main route is touching an infected surface and then touching your eyes, nose or mouth. Masks only help with breathing in droplets, and they only help if they're worn correctly. Incorrect mask wearing increases risk because masks feel weird and cause people to touch their face more often, and because masks give permission to people to go outside and mingle in crowds.

There's not much research around whether members of the public can wear PPE correctly, but there's plenty of research around PPE and healthcare professionals. We know that qualified registered healthcare professionals who know the consequences of not wearing PPE correctly still struggle to do it all correctly.

> Most people aren't idiots - if the masks help protect medical professionals from Covid-19, they can also help non-medical professionals.

The difference is that healthcare professionals spend all day in close contact with symptomatic people and are more likely to come into contact with blood or fecal matter or sputum, and are more likely to be doing aerosol-generating procedures, so the baseline risk is much higher, so that marginal benefit turns into an actual benefit. But importantly they're not just wearing masks. They're wearing gowns and gloves and eye protection and they have access to water and soap and alcohol hand gels and infection control teams to train them on how to wear it correctly.

> even a bandana can likely help prevent disease transmission

You're basing this on a small study carried out in a lab using research bacteria (not viruses) carried in a calibrated spray, that didn't include "people breathing through the mask". You've massively overstated those results.
It's a shame they aren't making that size anymore, it was such a nice elegant size. But I'm sure they looked at the data and know that they'll sell even more of these with the 4.7" because for most people on a budget it's their primary computing device.

It's about SENDING requests with "zero latency", not about completing http operations with zero latency.

And yes, you get no confirmation, and no reply.

I must admit I'm hard pressed to come up with a use case for this. You could just as easily do a regular HTTP request on a separate thread and throw away the result to get "zero latency" fire-and-forget behavior.
UDP doesn't implement:

- Reliable delivery

- Ordering

- Congestion control

- Flow control

...and a large list of RFCs that I'll never ever read.

If you are delivering a document (like a webpage or an API response), or transferring files, you want these things.

If you are doing real-time stuff, like video, voice, real-time games... and you just need the most recent information, that's where UDP shines.
HN always likes new communities. But don't do this:

yes probably - but I suppose the limit there is controlling what they can extend? The other thing with games is performance - prototype languages are slower in general.

I'm not against them - these are reasons I can see for not using prototype languages.

Edit: I suppose to the environment a developer wants isn't the environment that a game user wants, like a game user wants to just extend a few things - but having the whole self environment for arguments sake would be fairly intimidating I'd imagine.

Quick point: His parents were Anarchists - in the workers'-movement, anti-Capitalist, revolutionary sense, Groethendieck wasn't. Or rather, his activities did not involve Anarchist organizing/politics.

Also, in the summary, where it says "discovered a proof of the Lebesgue measure" - that's obviously nonsensical, he (re-)developed the Lebesgue measure himself, without being aware of Lebesgue's work. Or so it says; I don't know whether he actually focused on non-Riemann-measurable sets etc.
Yes there is a distinction between the two, but in this scenario they both needed to be considered. If you are making it more accessible to vote and that leads to a decrease in voter turnout is that a good thing? The claim of the GP was that online voting would increase voter turnout. If you only consider enfranchisement sure it would, you are making it easier to vote. But put in the wider and cultural political context of a given country my argument is that the GP's claim, that more people would vote, isn't guaranteed.

Hi dang

This was a good test but it failed some key characteristics to make it an excellent test message.

You didn't put foo or bar anywhere in the test message.

There was no Cthulhu phrases.

Plus there was no pi or the numerical answer to the universe and everything.

I trust you will take this onboard for the next test.

MSSSQL people seem really proud of their CTEs. What is it that makes CTEs in MSSQL so great?

I wonder if that really disqualifies Postgres from the same task. Are MSSQL CTEs just the hammer for your proverbial nail? Can you use a different approach in Postgres to solve the problem by leveraging its strengths?

My day job is a lot of Redshift. We use CTEs and temp tables depending on what we need. It’s based on Postgres but not really comparable when talking about performance optimization.
See also: the ASMR trend. A lot of the videos are emulating personal attention and ‘social grooming’ (someone doing your makeup, haircare, shaving, etc). And reiki, crystals, tarot, palm reading, and so on are all popular subjects too! Some section of the population, those who experience ASMR properly, have a unique physical reaction to this sort of attention and touch; and it’s obvious that large sections at least find it relaxing and calming in a way that enhances their wellbeing and gives them a feeling of social connectedness. To say it’s all debunked mumbo jumbo that won’t cure cancer is to miss the point!
True, but that's not as common as the vast, vast majority of people who just spend a comfortable amount of money on these things and become happier for it. We need protection against those bad actors, perhaps, but there will always be scammers in any profession. I also think those scams are small-scale in comparison to the vast "scam" that modern medicine has become, for Americans at least. Sure, the shaman can take your life savings, but he cannot additionally stick you with loans for whatever amount he wants that you cannot discharge via any means whatsoever. At least you just stand to lose everything, not lose everything and then some.
This talks a lot about Postgres (which is great ) but not about other databases so the title isn't very accurate. If you ignore cost it certainly doesn't explain why you'd work with Postgres rather than Oracle or SQLServer.

I've used Oracle for 20+ years, SQLServer for > 10 years, and Postgres from time to time and would say they are all good tools for a general use case.
In some sense the broader question is what about psychotherapy actual does the work.

So when I mentioned talking to some random high status individual who lends a sympathetic ear, that's one way to separate the factors.

Another one, with lots of practitioners, is looking at pastors and other religious figures. Pastoral care is a big deal. Whether you want to treat that as placebo or a special kind of psychotherapy is a judgement call.

If these examples work just as well (or badly) as Freudian psychoanalysis, then that's good knowledge to build on.

Perhaps they work better or worse than Freudian psychoanalysis. That's also useful to know.

See https://slatestarcodex.com/2019/11/20/book-review-all-therap... for how basically every kind of therapy can claim lots of life experience and critical thinking evidence in its favour.

> ”I really don’t need a webcam ... Why are these not optional on devices?”

The webcam is cheap enough that the cost to make it optional (ie: added manufacturing and logistical complexity of another model variant) would greatly exceed the cost of the part.

Most people (except some high security military/intelligence customers, perhaps) aren’t willing to pay more to not have a webcam.

One thing I always wanted to ask if why do job ads not allow comments? I'm guessing its to prevent negative comments/trolling (we get plenty of 'this will never work' on Launch/Show posts), but at the same time I feel like comments on job ads could be a good way for the founders and existing employees (tell us why you as a meager developer are excited to work there!) to interact with the HN community.

FWIW, Apple system (OS) updates frequently include firmware updates, not only for the FEP/boot code but other devices as well, especially for security issues. Apple has been pretty good about this.

Not addressing the rest of your comment, just this one point.

Indeed. But since it's so slow that I can see the blit happening, scanline by scanline, it's definitely what is happening, even if it's not apparent why. (I do know that the particular window manager in use decides to move windows back and forth by 2 pixels to work around some sort of bug.)

Not being able to explain why the software does this does not negate the fact that it is doing this, and that it is a quite different possible reason for lengthy pauses in the user interface, one of several, that is nothing to do with suspending the machine; indicating that, as I said, one should not assume that these things are always suspend-related.
No, clinical studies work by showing statistically significantly greater efficacy than the placebo (sham treatment) group. Placebo can be anything. Just as the treatment.

But it turns out that placebo is basically the measure of how much the patient believes in the treatment. And that correlates with price, attention of staff, length of treatment, etc.

We're not using arrow functions for everything. Why are you assuming this?

We're using shorthand syntax in methods inside Vue.js objects [1], they also don't need the "function" keyword. In fact, they are suggested in the second link you posted, please read again. Arrow functions wouldn't even work in this situation.

We're mainly using two forms: shorthand and arrow. That's how we only have 21 instances of the "function" word in our entire JS codebase, and we could remove all of them if we wanted. That's what you asked for: a "JS app that completely bans the 'function' keyword". Well, we don't ban but it's possible.

And please read my comment again: I explicitly mentioned that this is not a rule, and I never enforced it. The team (39 committers ATM) reached that result organically, mostly influenced by my own personal style.

And sorry if this sounds harsh, but it seems that you have extremely limited knowledge of Javascript and ES6, so I'd suggest learning before you make such claims before you make a fool of yourself.

Btw, you're seem to be the one holding on to dogma here, since you seem unable to accept that the keyword is not strictly necessary in a large app.

As far as I can tell this guy is a freaking PR genius. He managed to turn a leak into another chance to ram home his message.

The entire Vice article is ridiculous. People trying to organise a union smear their employers all the time, it's rather inherent in the task. Employers smearing back is now shocking behaviour? Double standards are rife.

I wish companies who want to avoid unions just treated their workers well enough that they don’t want to unionize — seems like the most straight up way to “fight” unions.

That's pretty clearly not the case. Unions aren't about being 'treated well' in so many cases, they're about granting power to the union organisers.

Look at Kickstarter. They got a union because they took down a project that was violating their own terms of service by fund-raising for political violence. The union organisers primary aim was literally to force Kickstarter to support violence against conservatives. Being treated well had nothing to do with it. Look at Google. A pampered workforce, talking of unionising to try and force the organisation even further to the left.

Smart managers fight unions with everything they've got, or else the most hard-left workers they've got will take over the company by force and subvert it to evil political ends.
