Interesting. That's a weird mixed video of different buildings from across China. I've been seeing a lot of vids like this lately. It's been hard to tell if they're just capitalizing on various Wuhan and COVID keywords to gain views, or if they're part of China's social media spin campaign.

Those compilation vids got me at first too! Other ones I've seen:
-Wild animals loose on the streets during COVID lockdown! (mix of true COVID clips, plus various wild-animals-on-streets videos over the years).
-Police brutality in COVID era! (mix of police smacking people for not wearing masks, plus assorted police videos from over the years).
-Traffic mayhem after COVID lockdown! (mix of recent COVID traffic events, plus miscellaneous road rage footage from over the years).
Medronics, a medical equipment manufacturer of a compact ventilator has made the design of their model PB 560 open source recently.
To access the files, you need to register on Medtronic's website. Beyond that, you are free to use the data to reproduce the ventilators. You cannot use their logo though. More info can be found here:
Some bits today.
Distinctions are being made between COVID droplet transmission and aerosol transmission, but it's now generally accepted that COVID is indeed airborne. Short NEJM letter to the editor with basics on this.
Mass transport systems are being carefully analyzed as routes for infection. This paper from MIT economist Jeffrey Harris examines some data supporting the belief that NYC's subways were largely responsible for mass infection.
I heard that Restaurant Depot is opening up to regular consumers. They usually supply just restaurants, but apparently they're issuing day passes to people, and they're doing online ordering and curbside pickup. They're similar to a Costco, but their prices are much lower. You need to buy very large quantities, but I've also heard that they're breaking down large quantity boxes into smaller ones for people.
For DIY Coronavirus builds, I like these homemade UV-C light boxes. Technically this is called UVGI - Ultraviolet Germicidal Irradiation. People are using these to decontaminate masks and PPE, as well as groceries and mail before bringing them into their homes. UV-C light is dangerous, so approach these builds cautiously! It can burn your skin, and it's a known carcinogen. This guide is helpful: https://docs.google.com/document/d/1...Oh3wa-UhCJ6ZU/ . This one too: https://www.n95decon.org/

I think this is real. Punishment for breaking quarantine in Colombia. More info here.
Some memes and funny stuff:
A wallet in the COVID age:
Some quarantine furniture. I wonder if alcohol sales are rising or falling. No more public events, but many people are stuck at home and unemployed. I think most of them aren't immersing themselves in their hobbies like we are.
I like this comic, because it reminds us that touching your face is actually really difficult.
