Worth the click even to just skim the hilarious images that illustrate the points.

Moving forward, masks should be readily available in public places in the same way tissues are.

For example, a large box or auto dispensing machine for individually wrapped, single masks, in libraries, grocery stores, offices, classrooms, movie theaters, etc.

And might as well add motion activated hand sanitizer dispensers at the entrances too.

It would be a separate entity, whose sole job is verification, not education.

Is there an equivalent "short term disability" insurance for companies? Where if some unforeseen event happens, they can still make 60-80 percent of their revenue for 6-12 weeks?

What we need is a credible credentialing system where you can demonstrate you've acquired knowledge comparable to a bachelors degree. Instead of just adding more walled gardens of degree granting institutions.

If wonder if we're getting closer to our brain's "algorithm" which takes reference images from the real world and generates newly imagined scenes when we're dreaming.

Anyone have links to play online?

Some sites I can think of that support other variants:

I think most "Lyric" videos, where the screen is a single image, or nearly the same image, can be compressed to be almost the size of just the audio.

If not, I would second the "zero pixel" option!

And it's the reason why FedEx and UPS have their Super Hubs where they do: https://youtu.be/y3qfeoqErtY?t=119

I guess that's one way to get a leg up on the competition.

Great, now I have to also stop scratching my face with my elbows.

There's a referenced journal article on the Coronavirus Wikipedia page [0] that says other coronaviruses can survive up to 9 days [1]. Can anyone corroborate?

I thought about this too. Imagine a glove that had thousands of micro pores (like your skin) that would secrete a tiny droplet of Purell. But not enough to be wet. Just enough to create a layer of evaporating sanitizer between the glove and the surface. Possibly pressure activated so it's not secreting all the time.

Exactly. I'm imagining a modern-day version of the scene in Apollo 13 where they have to find a way to fit a "Square Peg in a Round Hole"

I empathize with people who are trying to help by reducing their footprint. Though I fear it'll all be in vain when a machine is invented that can suck a lifetime's worth of frugality out of the air in a fraction of a second.

Similar to the infamous: "temporary" workarounds...

Check out Wikipedia's "Current events" section [0]. I feel it does the best job of providing the relevant factual updates about the world without all of the drama, clickbait and gossip.

How about a GitHub for science?

If we bring in topography, aren't we now running into a 3D version of the coastline paradox?

https://en.wikipedia.org/wiki/Coastline_paradox

So, yes, good point. Let's start with assuming a perfect sphere, then oblate spheroid, then topography, then only land (not water), and however crazy this thread gets with whatever else we haven't thought of :)

*Spherical cap

https://en.wikipedia.org/wiki/Spherical_cap

Bonus points for whoever calculates the ratio of the surface areas for the two spherical caps that contain half of the human population. (The circle's radius is ~4,000 km)

What metrics are being used to quantify/measure this?

The next big breakthrough will be a program that can convert TLA+ directly into production code. And create all of the necessary tests, with a formal proof that the code is correct.

The book's complete but they can't agree on what to name it.

Has anyone had success (or failure) in the real world with enforcing preconditions, postconditions and invariants? Has this caught bugs faster, reduced side effects and helped ensure overall correctness? Or has it lead to more overhead and longer development time without much to show for all the effort?

>> 1.5 gallons of fresh drinking water per hour for every square meter of solar collecting area.

So a football field could collect around 8,000 gallons of water per hour. Let's say you can get 5 hours of good sunlight per day = 40,000 gallons of water.

>> The team’s demonstration device can achieve an overall efficiency of 385 percent in converting the energy of sunlight into the energy of water evaporation.

>> Theoretically, with more desalination stages and further optimization, such systems could reach overall efficiency levels as high as 700 or 800 percent

So now we're looking at 80,000 gallons of water per day.

>> Unlike some desalination systems, there is no accumulation of salt or concentrated brines to be disposed of. In a free-floating configuration, any salt that accumulates during the day would simply be carried back out at night through the wicking material and back into the seawater.

>> In production, they think a system built to serve the needs of a family might be built for around $100.
