> Staff seem to get infected less frequently than other diners, even though they are in the space for longer. There are a few possible explanations, but the fact that staff don't take their masks off is a pretty compelling one.

IMO that’s the least compelling reason. One big one would be the staff having way more contacts and thus higher exposure to the other circulating hCoVs as well as SARS-2 itself.

The evidence for face masks is weak at best. In my opinion they don’t even make sense theoretically unless you pretend that droplet transmission is the dominant transmission mode, which is completely unproven yet widely believed dogma (go figure)

Implementation defined behavior can only ever produce compiler warnings, which you can choose to be commit blockers if you want. But if a compiler can prove that UB can happen then it can completely prevent you from building that program.
I’m comparing it to cities outside the US, SF is not dense at all.
This actually looks great!
It's amusing that people never seem to get excited about India and Pakistan's fight over Kashmir (and Apple has employees in India), England and Ireland's fight over Northern Ireland (again, Apple has a presence in Ireland) or other violent land disputes around the world where their company does business. And the civil wars in Sudan (Apple gets some "3TG" materials from there), and civil rights abuses in China.
Considering that the vast majority of cases of COVID are asymptomatic, it’s pretty apparent that the viral load needed to infect someone enough that they even exhibit symptoms, never mind need to be hospitalized, is not easy to achieve. As such, it’s likely even a 30% reduction (which is on the lower end of the range) in the viral load inhaled by someone could drastically reduce the chance of symptomatic COVID.

And when you combine 30% reductions for both the receiver and the emitter, it gets much higher.

Put the code under the GPL so no one can use it to build proprietary software. Visual Studio Code contains proprietary components, so this would prevent that.
You need mucus and it's a lot more convenient to dump it down the throat where it can pull double duty as lubricant and be recycled than have it come out the front all the time.

Nice site, only about 250 total, Wyoming, South and North Dakota have none, closest one near me in Florida is about 40 miles away.

Is amazing how fast the infrastructure is going in. Seems much easier to build charging stations than gas stations so long as the grid can hold up.
Could Idaho afford to incorporate that much more rural land without cities to increase its tax base? They purposely avoid even Bend because that’s where Oregon starts getting liberal.
I've been using Uber a lot since the beginning of the pandemic. I'm quite interested in how things work on their end some drivers are willing to share the 'painpoints'.

Cherry picking is bad for the customer, but:

1) In London, a lot of Uber drivers stopped going to central London because of the congestion charge. Essentially if you go there, you pretty much have to stay there all day to make it worthwhile.

2) They can't plan their time. Imagine you want to finish in the next 10min and pickup kids from school. Instead, you get to drive 2 hours to another city ( it does happen).

3) Long rides don't make much sense for drivers financially,so they often prefer local,shorter trips.
i now know of closures, and have actually used them intentionally, and rarely, and def not enthusiastically.

i lived mostly in the java world, and discovered closures when i was getting wacky results while playing around with a Clojure looping example.

then ran into similar situations about once a year when doing something in javascript -- usually passing some function for a callback, and needing access to 'this' in the original/calling scope - which only confused things when i needed access to 'this' in the (local?) function scope, too.

guess i'm not against closures -- they just seem mysterious to me.

ditto lambdas. they seem like a good way to write esoteric code, and write more error-prone/less-defensive code -- that, for instance, might be more likely to produce NPEs, and generally be less maintainable b/c of the focus on brevity instead of clarity, and be geared more towards expert users/coders instead of the generalists (like me) who are often brought in to maintain older code.

Except there is no convincing evidence that they actually do help others, and the whole theoretical mechanism is centered around catching large respiratory droplets which is at odd with the totality of evidence pointing towards aerosol being the dominant mode. I would add if droplet transmission is the dominant mode, which I very much doubt, then masks would still fail in a real-world setting when you look at the fact they make conversational partners stand closer or speak louder, and the massive cross contamination that happens to almost everybody wearing these pieces of cloth over their faces (hands touch mask, mask touches hands, etc)
> When the plane didn’t land, she went to the runway manager.

One of the fascinating dynamics of small towns is the casualness of interactions like this as everyone knows everyone and it is considered perfectly appropriate to try and talk to anyone. The plane didn't land, so she went to see the runway manager. She just did.

I wonder how often this happens in big cities. Do people ever email the airport to ask why a plane missed an approach?
Same thing happened to me with Digi-comp II, although I was the kid and I thought that I had screwed up the assembly. The model printed on the cover had wooden bars and looked a lot more reliable, but the production model was plastic and not reliable at all.
I think this is great. I think urban places that believe in communism are perfectly within their right to exercise that kind of self-abuse, and the surrounding rural areas should not have to participate. According to these urban centers, the rural areas are just an economic drain anyway, so it behooves them to get rid of their lowly rural neighbors and become the urban superpowers they were destined to become !
I suppose they wouldn’t be if your entire electoral profit and loss statement comes down to one seat in the goddamned House of Representatives and we are all slaves to lines on a map because those lines, those lines are destiny.

But srswtf123, seriously, wtf? You tell me how many offices you were asked to fill in the last ballot you filled out and how many completely asinine laws you were asked to vote yes or no on. Constitutional amendments are two points if you got any of those on your ballot. In my neck of the woods, the locals love sticking complete crap in our constitution to keep it outside the reach of State courts.

I spent a semester in college in the Czech Republic with international students from all over Europe, all of whom spoke English. All the Americans learned to speak “European English” — slowed down, more verbose, without slang — because we were frequently told that we could not be understood otherwise. It became pronounced enough that people I would talk to back home would notice it. And for what it’s worth I couldn’t understand the students from the UK when they were speaking to each other either.

Isn't checking for overflow depending on UB? i.e. in

int a;
// lots of code
int b = a + 1;
// check for overflow
if (b <= a)
abort();

the compiler is allowed to remove the check because in the absence of UB a + 1 > a, therefore the conditional is always false.
Far out! But. Is there no end to our collective madness!

Don't be silly, we're not talking about those values.
These people are nuts if they think Apple is going to put out an official statement saying that Israel is illegally occupying Palestine.

In their letter they dismiss the notion that the issue is complex and can't be boiled down to the company simply saying "we support X" or "Y is in the right here", but that's exactly what it is. A consumer electronics company cannot be expected to make sense of and take sides in a centuries-long religious and geopolitical conflict.

The Agricultural Revolution: History's Biggest Fraud
There are some programs out there that are OK, but I think the gist of the problem is you are missing out on free market forces like price discovery, private equity, and are manipulating risk so anything the government touches ends up becoming less efficient and built with different constraints.

Of course, there are times when efficiency is not the thing we’re optimizing for. The Space Program is an example of a pretty great government program; there was no profit or benefit to private space travel in the 1950s and 60s so the government had to subsidize it, but now that we are starting to see private business catch up, the best thing to do is get government out of the way. This is not all that different during the Age of Discovery where kings and queens subsidized trans-oceanic travel.

IMHO government should only exist to fix free market deficiencies (Monopolies, unfair competition, fledgling industries, lack of players). Not to take over a market and try to dictate it from the top down. Ultimately the goal should be that all people make enough of a wage to afford healthcare and let the market handle it. And still have a safety net for those who fall through the cracks, but the safety net should never be the goal.

> If that were the case, wouldn't signed overflow be implementation-defined or unspecified behavior, instead of undefined behavior?

No, because (among other reasons) the processor architecture might decide to trap or not trap depending the run-time values of configuration registers that the compiler doesn't know and can't control or document.
>There is no need to. If it's about talks history, chats are not right tool then, forums are more convenient.

This sounds like a fox and the grapes situation. You can't see history on IRC so rather than noting the deficiency, you list it as a feature.

As a modern IM user, I am part of many low volume groups and the history is essential as there will usually only be 5 or so messages in the day which I would have just missed if I had used IRC. I agree that history on a fast pace 100 member chat is not so useful but not having it isn't a benefit either.
“Evil Geniuses: the unmasking of America” was pretty good at tracking this. Basically politicians are using the framing of the glorified past within “American values” to manufacture dissent and create us/them other-izing between US citizens. The book explains it much more in depth. Get people to stop thinking of their fellow citizens as part of the same group as them in a fundamental way and chaos reigns. Maybe eventually it’s civil war. (It definitely drives that country from thinking of international factors.)

Probably another interesting definition of American values would be the ones held in foreign people. Sort of in the same way there’s who you are and then there’s the person in the minds of everyone who knows you. Except the US is a super power that’s done a lot of steering the world over the last century and that’s instilled some common practices across the world. Like citing CDC guidelines or using the US currency for reserve.

Fox News reports the same dumpster fire each night (often just reusing video footage each day), I’m not sure how serious they are if they are aiming to burn down the courthouse. Yes, dumpster fires are illegal and those starting them should be punished, but it’s a stretch to say they are trying to burn down the courthouse.
> meaning your speed through the space direction is comparatively low

But you do move in space at a great speed if you account for the rotation of the earth around the sun, the movement of the solar system in the galaxy, and the movement of the galaxy relative to other galaxies. It's not like there's a coordinate system with an absolute origin somewhere.
For exercise I recommend ring fit
The Vietnamese study found that cloth masks increased risk compared to medical masks, not compared to no mask. Confusingly, their control group also wore masks, just in fewer situations:

> Hospital wards were randomised to: medical masks, cloth masks or a control group (usual practice, which included mask wearing).

The first paper doesn't say what kind of mask the control participants wore, but a subsequent paper says only 38/458 control participants wore a cloth mask. I think the implication is that the rest wore medical masks, though neither paper ever says explicitly.

https://bmjopen.bmj.com/content/10/9/e042045

That subsequent paper is a subgroup analysis that should be treated with some care, but found comparable performance between medical masks and cloth masks washed in the hospital laundry. That suggests the problem was inadequate hand-washing, not the masks themselves.

There is zero evidence that masks increase incidence of disease compared to no mask. RCTs of mask use in public (e.g., DANMASK-19 and earlier flu studies) suggest that the benefit of the mask to the wearer--excluding the benefit of the mask to others nearby from source control--is less than a 50% reduction in disease, with a 95% confidence interval centered somewhere around 20% but including zero. The RCT evidence says nothing beyond that.

Public health authorities have indeed spoken with unjustified confidence as to the efficacy of masks. You're doing the same thing here in the opposite direction, though. Given the information above, can you correct your comment?
It's not a bad thought, though there are a number of challenges. One thing PoW has going for it is that the difficulty of computation is well known and easy to adjust.

Specifically for the codec cases, it's not that we can't come up with better codecs, but that they require more computational resources to encode and even decode. We have ones now that are still a bit much for mainstream and using bandwidth/storage is a better market fit. As for the 'overall quality' this is subjective. Anything objectively defined is optimizing for something humans may not appreciate.

So what we're talking about is generalizing the hard to compute, easy to verify of finding hashes to other computations that are useful to some parties--a computational market. I do rather like this, like kickstarter for computation. A problem gets posted, with a verifier. People can choose which ones they want to sponsor and how much. Solvers can choose which problems to solve.

Even thinking this through, I think it's still useful to have a PoW hash-based blockchain just to record the first solutions. So we're back to being limited in the number of solutions we can record per second.
How can they be your competition if they don’t offer a comparable product or service? That’s not any kind of competition I understand.
