In what direction? I think part of the point of this paper is that most masks aren't taking things seriously enough.
magduf · 5 years ago
No, the point of this paper is that masks are not completely, absolutely, perfectly, 100% effective and foolproof, and therefore we shouldn't use them at all.

I really have to wonder if the people pushing this have some kind of agenda.

Jeremy Howard (of FastAI) is doing a major metastudy on masks at the moment. Pretty sure they work.

Correlation doesn't guarantee causation, but the Asian countries where mask-wearing has been commonplace for a long time have done far, far, far better with this pandemic than nations where no one wears masks in public.

Cloth masks can definitely help though. They are good at one thing in particular, reducing spread and velocity of air movement from your face. If you breath, cough, or sneeze, the transmission distance is highly reduced. You still have virus escaping, but it cannot travel as far.

This is the key here, and what all these "masks don't work!" people seem to constantly miss somehow. No, masks are not 100% effective at filtration; any idiot can see that. They don't have to be 100% effective, they just need to be better than nothing, and that'll slow the spread of the disease. Keeping people from spewing germs 20 feet when they sneeze or cough is a big help in slowing this pandemic.

There's a reason masks have been commonplace in Asia for many years now: they're meant to protect society, not the wearer. When someone thinks they're sick in Japan, they're supposed to wear a mask to keep everyone else from getting sick: it's good manners. It only works when lots of people are doing the same thing.

Similarly, the cloth masks are actually called "surgical masks", because they're normally used in surgery. They have absolutely nothing to do with keeping the surgeon safe from the patient; they're in place to keep the patient, who has a huge gaping wound in his body, from being infected by droplets from the surgeon as the surgeon bends over the wound site, and is breathing and talking to other people.

That's funny - I always think "maybe we'll talk about the composer instead of that dang keyboard layout this time!"

Why can't we have both?

We can always stop buying HDDs.
magduf · 5 years ago
I've read that SSDs can't be used to replace HDDs for long-term archival use: if you leave them powered off for too long, the data degrades. I can store data long-term on a regular HDD and stick in a closet or safe-deposit box and then get it out after a few years, plug it in, and read it just fine.

Yeah, that's terrible advice. They advertise these as high-end prosumer drives.

To the product manager at WD who is inevitably reading this: if your hardware doesn't live up to your own marketing, I'm not going to throw more money your way. I'm switching to your competition.

The WD product manager's response: "Bwahahaha!!! Seagate's drives are crap too, and we own Hitachi! Where are you going to go now? Bwahahahaha!"

> it's not necessary to completely overthrow a government to extract concessions. a credible threat of widespread chaos and violence might tip the scales against a very unpopular policy.

And how often does that actually succeed? The American Civil War caused the South to lose out on slavery, at great cost to its economy; while The Troubles didn't induce the UK to give any concessions it wasn't already willing to give beforehand.

Most insurgencies ultimately fail in their aims, and this is already when we're talking about insurgencies against weak governments and civil societies where monopoly of force is close to nonexistent in the first place.

>while The Troubles didn't induce the UK to give any concessions it wasn't already willing to give beforehand.

If you look farther back in Ireland's history, it seems like Ireland's independence from UK was achieved mostly by violent resistance. After there was too much violence, England finally decided it wasn't worth it, and came up with an agreement allowing most of the island to become independent, with the exception of a handful of northern counties.

I read it all and while it's great that he has a legitimate reason to own these, it doesn't change the fact that he owns a private air force, heavy weapons and state-of-the-art countermeasures. It's a terrifying legal precedent and he's opened the door for a new market niche that less savory people can sneak into.

The US already has ludicrously expansive personal rights to weapons ownership for any reason. We have a guy buying up a private air force. We have several guys building space vehicles. If Elon Musk or Jeff Bezos wanted a nuclear-armed ICBM could we actually stop them? Or, maybe more likely, some QAnon nutjob getting his hands on an armored vehicle and driving it through a shopping mall in Atlanta?

magduf · 5 years ago
What exactly are nutjobs going to do with any of these weapons?

We've had cases of nutjobs getting their hands on tanks, or building their own armored bulldozers, and going on rampages. It's a pain, but it's not a complete disaster. These vehicles aren't invincible. They generally get stuck somewhere, and then the police break open the hatch and shoot the nutjob. Tanks really can't do much by themselves besides drive around and run into some things (or over them, but again, you have to be careful or it can get stuck, break a tread, etc.). Tanks armed with 120mm cannon rounds, of course, can do some serious damage, but private individuals aren't allowed to own that kind of weaponry at all.

It's the same with an older fighter jet. What are you going to do with it? Fly it into a building? Sure, that'll be worse than flying a Cessna into a building, but still, it's not like a WMD. Even if you could fully load the 20mm cannon, you're not going to do that much damage; they don't hold that much ammo anyway (only enough for something like 5-10 seconds of sustained fire I think). Yeah, being able to drop a bunch of 500lb bombs would be a disaster, but again, you can't get that stuff.

Yes, if Elon or Jeff wanted a nuclear-armed ICBM, the government would certainly stop them. Building a rocket is one thing, building a nuclear warhead is something else entirely, and is not something trivial that just anyone can do. Iran (an actual nation-state) has been trying for some time and still hasn't succeeded as far as we know. It takes a lot of facilities and special materials to build something like that.

It's often more expensive to create specialized training capabilities in house. Contractors have an advantage with both equipment and personnel costs.

A contractor can maintain their jets however they want as long as it's safe and they can meet their contract requirements. The contract maintainers can stay at their job as long as they want. The USN and USAF maintainers move every few years and have pretty good retirement benefits (which used to be better but are still better than what most private companies give), and have to get lots of additional training and all that needs to be paid for. A contractor is still supposed to follow all the safety regulations, but contractors seem to be able to generate sorties at rates that military units couldn't manage even with double the manpower.

Contractor pilots are paid strictly to fly. Naval aviators and USAF pilots are both subject to "up or out" policies, where officers that aren't promoted are told to leave. This means military pilots have to serve as staff officers to keep themselves promotable. During a staff tour they either quit flying or they fly less, which kind of wastes the money spent on training them. There are good reasons for requiring this (and some good arguments against it), but the bottom line is that contractors don't have to worry about it and can operate cheaper because they aren't wasting 20% of their personnel budget with a fighter pilot working behind a desk.

Sounds to me like the military is simply shooting itself in the food with its "up or out" policies. Why force highly-trained and experienced people to leave just because they've gotten to a plateau in their career where they're both competent and comfortable?

Do foreign militaries also have these policies?
