the point with wearing masks at all times in public space is you don't have to take it off and put it on all the time you pass around someone, you never know when there will be someone around you and even if you are alone you can still cough the virus on surfaces where it can survive at least for few hours touched by other people

I agree it's quite pointless for healthy not coughing person, but it's just easier to order everyone to wear them than checking one by one who is sick and who is not.

not sure how is mask wasted, if it's cloth mask you can just microwave it or boil it, if it's medical mask you can just leave it on sunny surface until it's for sure clean again or microwave it, same applies to respirator

Proud owner of Steelcase Leap V2

I find the Leap more comfortable for sitting long periods of time. The Leap also allows me to sit on one of my legs (I know, not a good idea), while the Aeron makes this impossible. The Leap also has more adjustments for the arms which I move quite often. Regardless of the chair model, take frequent breaks and our back does not made for long sitting!
...you would not like the result of that purity...

The marketing, at least, is exactly like 2008. With the benefit of hindsight, we find that we don't like the results of impurity. The logical response is to choose more purity this time.
There is nothing weird or tricky about buybacks, and the mechanism is pretty obvious and intuitive.

A company can issue new shares and raise money when they need it.

A company can buyback shares when they have extra money they can't efficiently use (see: AAPL, MSFT, GOOG).

There is absolutely nothing nefarious about this mechanism, and if tax treatments vary blame the government (don't hate the playa, etc).

Buybacks are only a problem when cash-poor companies do buybacks. Either they're depleting a small contingency reserve, or they're even utilizing debt to do it.

Agreed on the dangers of sawdust, but in my experience most hobbyist woodworkers these days are very aware of dust and particulate management.

Particle counters are reasonably cheap, so many woodworkers use them to measure and optimize the air cleaning systems in their woodworking areas.

It helps that the most popular Woodworking YouTubers frequently produce videos about improvements to their dust collection setups. It also helps that cheap Chinese air filtration units have become widely available.

Dust collection and air filtration are probably the most common tool talk in my local woodworking groups.

In contrast, it's rare to see electronics hobbyists taking air filtration seriously. Kudos to Ben Heck for writing about it.

Monstly agree - but dividends that go to every owner aren't unfair per se, a cap on dividends would be very good, though. As for options, depending on the company they can be a hiring incentive, and not being able to grant any may restrict the company going forward - has to be evaluated carefully.
It's not working for me. I click the A4 PDF on the Monster Mash page and it takes me to a fullscreen Dopplr ad that I can't do anything on other than sign up for Dopplr.
After I got out of the military (in Electronics) I did a few years as a rework tech at a big telecom company soldering literally 8 hours a day. I got really good at it.

We had very little safety equipment, and used leaded exclusively. Vent hoods, but that's about it. Many people turned them off because the shake and rattle of the fans made it difficult to work on precise things like surface mount components. There was even a big CPU changing station which was effectively a molten vat of solder that you'd dip all 144 leads into to remove huge square I.C.s

This was in my early 20's, and I had that job for about 2 years. Despite perfect dental hygiene, most of my teeth had decayed and had to be crowned or replaced by the time I was 30. Most people I still talk to from that time in my life have chronic problems directly associated with lead poisoning (tooth decay is sort of loosely correlated, and I don't have any other typical symptoms into my 40s)

All of this is to say, the US Navy barely even mentioned lead safety in school, and a billion dollar (at the time) company didn't seem to care enough to train its employees, so the attitude that it's "not a big deal" was well and alive in the 90s, and I wouldn't be surprised if it still is today.

Also - Why is rosin-core solder so popular? I never used anything but raw spool solder and liquid flux. Rosin core makes a huge mess.

Building a web app with functional programming languages – Haskell librairies
In terms of the implementation, it's kind of trivial to implement the "magic", but it would be both confusing and inconsistent, see below.

e.g. imagine a case where you'd want to call datetime.strptime, partially initializing it at the moment of conversion definition.
at the moment it is:

c.call_func(
datetime.strptime,
c.item("updated"),
"%Y-%m-%d"
)

but it's unclear to me how would the "magic" approach deal with the case above.

Jim Williams used to lick solder as he was soldering as did other old-timers. Another observed behavior was licking the thumb and wiping the joint immediately after soldering.

Later he developed Parkinson's disease (probably related [1]) and died of a stroke.

Doctors in television told us that we should always throw away used medical masks and respirators as they might contain viruses and you are risking infection if you use them again.
>If you chose evil, you really chose to be with Satan forever, and God honors your choice and free will. If you chose good, God honors that choice as well.

That's not consistent with Christian teaching (or, as I understand it, much Judaic teaching that doesn't even have a Hell.)

It doesn't matter if you choose good or evil. According to Christian doctrine, all humans by default (even, according to some verses, infants in the womb) are destined to burn in Hell unless they've been saved through grace by Jesus. It's innate to the nature of humanity due to original sin, and that sin originates from free will itself, which humans were never meant to have, according to Genesis. It's the result of eating the forbidden fruit and "becoming like God, knowing both good and evil."

The person who spends their entire life being morally upright and law abiding, doing good, and helping others? If they're not saved, they burn, too bad.

Hitler earnestly prays for salvation before shooting himself in the head in his bunker? Gets an eternity of bliss in paradise. The millions of Jews he murdered? Not so much.

That's how it's supposed to work. Like, unless you know the bouncer and the secret handshake, you just don't get into the club.

> “Stock buybacks made as open-market repurchases make no contribution to the productive capabilities of the firm. Indeed, these distributions to shareholders, which generally come on top of dividends, disrupt the growth dynamic that links the productivity and pay of the labor force. The results are increased income inequity, employment instability, and anemic productivity.”

> “Stock buybacks made as open-market repurchases make no contribution to the productive capabilities of the firm. Indeed, these distributions to shareholders, which generally come on top of dividends, disrupt the growth dynamic that links the productivity and pay of the labor force. The results are increased income inequity, employment instability, and anemic productivity. [...] because of corporate tax cuts, in 2018 taxpaying households were burdened with about 38% of the combined government and business debt that enabled corporations to do buybacks.”

I'm a fierce capitalist, I love human sweat and I admire those who create value. Whether Jane the CEO or Rob who makes delicious cookies, value is value, value is good, value is shared (or should be).

Stock buyback is stealing though, plain and simple. It's a legally, cleverly twisted, inverted Robin Hood mechanism at the private level. It's basically everything that's wrong with finance in abstraction of value.

Expect tighter regulation promoted by Central Banks in the 2020s or we're heading for another income inequity-snafu. For those who haven't read much economy, the gist is this: not enough income inequity, and society stagnates (underperforms relatively to others under comparable conditions). Too much inequity, and the system chokes on itself (not enough consumer liquidity ⇒ you know...— and if you don't, think: consumer liquidity is the difference between pre-WWII and post-WWII global economies.

I'm not an economist and absolutely not an expert (I only did 2 short years of econ in university, and self-taught some financial-survival skills). But this is like 101 to me, the basics of a macro-econ intro. It's not even controversial, or hasn't been since post-Keynes basically.

Many small businesses do operate on thin margins and have little cash reserves. Most restaurants, for instance, won't be able to pay their rent and salaries with no customers in the dining room. Heck, many large and very profitable businesses don't have a lot of cash reserve either, because of shareholder demands. It goes into stock buybacks, dividends, and other investments. They're not holding anything for bad times. Which means, when this is over, they'll get eaten by the ones that do.

1M+ deaths is impossible based on .gov's own numbers. Estmated 100-200k dead. The only way a hospital can help is with ventilators. Everyone else gets the exact same treatment at home or not. If we have a 90% death rate on ventilators than in an absolute worse case 'system overwhelmed' scenario there are 10% more deaths. The idea of millions is laughable, but to be expected from political opinion pieces.
Maybe the best solution is to use a tool like https://github.com/wangyu-/udp2raw-tunnel.

Skin-Based Health Monitoring with BodyNET
The problem is that X includes a nonzero risk to human life/limb that is the responsibility of the person doing X. If you are in charge of a hospital and just let Y people die because there's not enough qualified doctors to run ventilators then you can easily wash your hands of it as though it's not your fault. If you let less-qualified people run ventilators and Y/10 die from human error but you prevent 8Y/10 people from dying then all the families of the Y/10 that died from error are going to hold you responsible even though you minimized the number of overall deaths.

We have spent decades holding people systemically dis-incentivizing people from doing positive things in bad situations by assigning responsibility in this perverse "who was the last one to touch it" manner. Society has made its bed and now it gets to lay in it. Nobody is gonna be the one that bucks the trend and reduces and sort of real or perceived safety standard in order to increase volume of care until the situation becomes so obviously bad that not doing so is indefensible.

If you think that's frustrating, wait until you read about Antibody Dependent Enhancement [1], which is the situation where antibodies from a previous infection actually enhance the virulence of a subsequent exposure.

Immunology is complicated and dynamic. That's why it takes 12-18 months to prove that a new vaccine won't end up being worse than the disease.

If traders credibly believed that a stock's value was going to 0, then the price would already be 0. Just saying in advance that your scheme was about to be implemented would crater the price before any new stock was sold.
I think it's safe to say yes, given that human's evolutionary ancestors lost the ability to produce vitamin C ~60 million years ago and there's no reason to assume they didn't require a similar diet to our own. To your larger point, that has always been the case from what I've seen from archeological and anthropological studies. Take Pokeweed for example which is toxic unless it's boiled three times in salt water.

However, the larger point of the article is that Neanderthals were a much more intelligent and adaptable species than we've given them credit. Given this evidence of food it would not be surprising if they found net sinkers or other tools associated with fishing. It seems every time we learn more about Neanderthals the more they resemble our species than not.
Sure, however he didn’t directly say the virus is a hoax. So you are projecting an unfair interpretation because you don’t like him. That’s just going to further convince conservatives that liberals don’t ever give the president a fair shake.
But at the same time, you'll find loads of people who don't eat meat. They just eat fish. Try asking a catholic if they eat meat during Lent, and they'll all tell you absolutely not while chowing down on a fish sandwich.

Like a more concentrated sunburn. A welding torch will create much higher intensity UV than you're typically exposed to, and you're staring right at it. So instead of your skin, it burns the cornea directly. I've always heard it called "flash burn" after the flash caused by welding.

Just because the article doesn't tie everything up in a nice back and white bow doesn't mean it is low quality.

The answer to the question is "we don't know, it's complicated". It's not a screenplay we're in, reality is messy.
Let me see if I have this right.

When a company cuts employees' salary by a significant amount (let's call it 25% of 75k = $18k == $1500 over 1 month, for argument's sake, but which we know will become 3 months) without knowing how employees will make it up, it's understandable and even acceptable -- just poor luck. But when another company cuts employee's salary by a fixed amount defined by what they are getting from another, guaranteed source -- thus making them whole -- they are monstrous?

ok, got it.

i, for one, would much rather face this than furlough or layoffs.
You don't need Saas for that. Just upload the images in a S3 bucket and set the access to protected. You can make a PUT request to a pre-signed URL for that. For GET just create a lambda function that GETs the image if it passes your criteria (create time, secret key). It's less than 5 lines of code.

There have been a few edits to my answer since I originally posted it. The original version had a bit at the top about it being against the spirit of the question but intended to amuse. It's not a practical solution at all.

Re 1: I'm not sure there was any particular inspiration. I've worked on quantum computing since 2004, so I guess I spend a lot of time thinking how to make computers in weird ways. Plus I spent college working at a number of ISPs doing tech support, so I used to be reasonably up on networks.

Re 2: Yep. In my field there is this idea of quantum sneaker-net. This is far more useful than my answer and potentially solves a major problem in the field I work in, but is also totally off the wall.

The basic idea is that you can make an extremely high speed low latency network for quantum communication by shipping giant refridgerators around the world on ships (using a quantum effect and the existing [non-quantum] internet). The paper is here: https://www.nature.com/articles/srep36163

Re 3: Somebody here pointed out pingfs which seems to take the idea to a whole new extreme, but reading the website it seems like it was already being worked on in 2011. I doubt anyone implemented my answer in any way. It was somewhat intentionally impractical.

Correct me if I'm wrong, but doesn't PAC on real data usually just tells you that "it doesn't know the answer"? Like, it says the equivalent to: "I think this is the answer, but it might be miles off and I give it 50% it is even more than miles off." I found that it is able to give hard guarantees, by being very loose on the bounds. Do you have a real-world example where it actually gave something useful? I'm genuine curious, because I discarded it early on, but am willing to revisit it.
I know, but the performance takes a massive hit. Have you tried it? Maybe it was something I did wrong.
It's a lot more if you do it all manually, however for most "common" use cases, one should probably go with automatically generated config files.

For instance pfSense provides you with single-click configs for any target platform, with certs, credentials etc. properly tied to some ACL or ID management system, etc. It's neat and pain-free and just works.

You could learn all the theory underneath (I mean systems, IT, not the crypto!) and do it manually (and you probably should for a big-enough infra, or specific-enough use-case), but that will be premature optimization I think.

Basic VPN is easy (take a weekend to learn / implement and you'll have all the great benefits of VPNs). Wireguard is "just" more efficient by an order of magnitude as I see it, it'll become the de facto low-profile implementation me thinks.
