Two modern techniques for building are SIPs (structural insulated panels) and ICFs (insulated concrete forms). Both methods involve foam insulation and also reduce the time to build. They're both just as costly, though. SIPs are constructed in a factory and the panels are trucked to the jobsite but exterior siding and interior drywall still need to be done on site. Stone and brick are great materials for longevity but are less energy efficient.

We blocked them a long time ago. They really are awful.

There are channels built into the wall for wires to go through. Plumbing is typically through floors to avoid thermal bridging in the walls.

Mastodon.social is still open to them afaik

That block was preemptive on a lot of instances. I know my admin proactively blocked them as soon as we knew what domain they would be federating from.

That's okay, most fedi instances have already blocked them. The flagship Mastodon instance is the only one that's being so welcoming to Zuck.

I agree smaller dose intuitively means less of a hazard of an infection putting down roots before the immune system wipes it out. However, I've never seen data for this.

IIRC coronavirus particles were around 0.1 um, but the virus would fall apart traveling bare. N95 do filter in that range in any event, just not at the advertised and tested level of an N95's 95% @ 0.3 um (you can get N100s which don't quite hit 100%; it's a rounding thing). Aerosols are typically much larger, 1+ um up, then transition to visible droplets around 20-100 um.

Was any of this data published? I wondered specifically about N95 claims for cheap imports.

I wait for the graphic novel version: https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fxkcd.com%2F2523%2F

I'm afraid another pivotal concern may have been costs: inferior masks such as surgical are much cheaper. So, here in Virginia the hospital admin logic went, the mask they chose should be the standard for all purposes (our hospital required visitors to give up their personal N95s for a surgical mask, which was at least free).

As even more damning evidence of institutional thinking, the same hospital network required my PCP to wear a mask for telemedicine visits. I burst out laughing when I saw him and asked, "I don't mean to be rude, but are y'all familiar with the germ theory of disease?" He apologized and said the rule simply was that all patient-facing meeting required a mask. So there, standards.

Kudos for being the one who actually RTFA!

I suspect someone has an agenda against President Biden here. The stories jibe fine.

Another thing he did was add a ton of debt to the balance sheet that has to be serviced. Twitter was already unprofitable as-is but he has made that a much tougher hurdle with all that debt.
