I'm not religious, but I'm taking a "Lenten fast" from social media, only checking in on Sundays.

When managing school classroom environments for infection prevention, AIRAH highly recommends that the report references the use of real-time infection risk models, such as that developed by Mahmoud et. al. in 2025. Models should be capable of assessing ventilation and f iltration system performance by using real-time particulate matter measurements for estimating infection risk and safe occupancy time. Such models support public health decision-making by defining maximum allowable class durations and break intervals, and support facility management in identifying zones where occupants can safely remain for longer periods, while highlighting areas that require intervention or restricted use. This enables optimisation of seating arrangements, allocation of high-risk activities such as speaking or group work, and evaluation of the impact of adding or relocating HEPA filters. From an engineering design perspective, these assessments

Anything below 410 I'm going to start thinking about instrumentation error. Instrumentation error and poor calibration are huge issues in physics and engineering. Traceable standards matter.

Spoiler alert - @ipaccanada.bsky.social still insists it is not airborne. In 2026.

a dangerous gap that Russia quickly exploited.
In 2008, Bush tried to fast-track Ukraine and Georgia into NATO, but France and Germany blocked it

Ukraine is an incredibly rich and powerful country that is striving to become truly European and Western - while rejecting Putin’s aggressive nationalism

John Bolton: Our biggest mistake in the 1990s and during the Bush administration was leaving Ukraine, Moldova, and Belarus in a gray zone - not pushing harder for their eventual NATO membership.

Eastern and Central Europeans were begging for protection from Russia. We expanded NATO but left

I am confident that AOC and I would disagree on some foreign policy issues, but I am also confident she would listen to advisors and so probably just end up doing The Blob stuff, which for all people complain, puts her ahead of three of the last five presidents and exactly even with the other two.

Let me get this straight.

He can’t even think of a PROMPT?

What part of this end result is something for which anyone should pay him? If you can’t even write the prompt, what is your contribution?

YOU’RE NOT EVEN TYPING.

And everyone in the chain of command was OK with it, for anyone still wondering if the US military will carry out whatever orders the administration gives them.

A BRIEF HISTORY OF THE RANDOMIZED CONTROLLED TRIAL: From Oranges and Lemons to the Gold Standard The science of medicine in the last 2 centuries has expanded and enhanced the knowledge of the body and of the pathologic conditions which threaten it…

Wow. This is an important line:

"The reader will note that each of these important studies validated a preventive method, not a therapeutic intervention."

And here we are, full circle, blindly and ignorantly applying RCTs to prevention like masks & HEPAs 🤦

Ergo: the definition of "good ventilation" needs some better science behind it.

By "good ventilation" they mean CO2 < 800 ppm, but don't mention ASHRAE 241 or even CADR. And they find a correlation between CO2 and detection probability. So more like, "study shows more attention to actually good air quality would reduce hospital infection risk".

May it be the first of many!

Hospitals are killing people with unnecessary infections because their internal politics are more important than patients' lives. Make negligent IPAC leaders pay a price - in money, but also loss of licensure and public humiliation - and the deaths will stop overnight.

I know Jimmy slightly, both online and in person, and while he's in the files it looks like it's only on the receiving end of mass e-mails. He did a couple of edge dot org things in 2007 or so. I'd need to see a lot more before I thought he was on the dark side.

I work at a university with a large medical arm so most of my healthcare is received at my employer, and I can think of few things I want less than my employer using AI to eavesdrop on my conversations with my doctors.

And that's not even getting into the question of AI accuracy and reliability.

Prime Minister Carney is brilliant
🇨🇦

His New World Order concept includes a new trade deal among 40 nations in Europe & Asia

The Super Alliance will be the largest GDP force on the planet

Behold the rise of the Middle Powers

Super alliance - $60T
USA - $28T
China - $20T

Also, note the date on this thread and the last tweet. A year before Trump was elected. Dave said exactly what all of you were going to do, and you did it.

This the skeleton key that explains the entire left-of-center political and informational environment. There is no social reward for ever saying anything nice about a mainline Democrat, so no one does. As a result, baseless antipathy towards the party completely pervades the environment.

Preventative Healthcare is an oxymoron, unfortunately. Prevention is engineering.

This piece captures a lot of what's driving my frustration lately. I literally said to my husband last night, "I have to stop reading words written by idiots who think they're smart or else I'm going to turn into the fucking Joker."

When you say "vote blue no matter who" these guys always say "oh ho ho, but what if it was Lina Khan, would you vote blue THEN?"

And the answer is "yes"? Very obviously? Was "vote blue no matter who" unclear?

I am still confused by (and strongly disagree with) the idea that reporting how many people survived an overdose at a hopsital in a given year violates any kind of patient privacy.
But that's the excuse two health authorities used for not releasing overdose data. The rest largely ignored me.

I'm seeing this get shared around in lots of places. (So apologies for picking on Judy) But it is sloppy research.

Crucial paper published Friday that deserves much more attention in the #LongCOVID world: www.nature.com/articles/s41...

TLDR: 13/15 immunocompromised patients who had chronic COVID infections (>200 days) cleared the virus in under 2 weeks when given combo antivirals/monoclonals

I’ll never understand how the majority of people are completely unaware—or act like they are—that it can take 10+ years for the long term effects of some serious viruses (HIV, EBV, HPV, polio, etc.) to appear. It hasn’t been 10 years since COVID arrived, but the existing science should urge caution.

As someone who did vote during this ICE bullshit, so many were motivated to vote because of a) ICE bullshit and b) the Republican candidate texting us to “stop fraud,” that everyone went out of their way to vote an already non-competitive race. The Democratic candidate put up Kim Jung-Un numbers.

Epstein Epstein Epstein.

Every single person who supported and benefited from Epstein and Maxwell needs to pay.

Physicians cannot on the one hand completely ignore air quality and then turn around and say to engineers, "Oh, no, you can't do engineering standards on air quality, that's our domain!"

OK, if physicians have nothing to say about air quality they will have nothing to say when engineers and occupational safety people impose scientifically justified legal standards to regulate it, including continuous-wear N95s for everyone in all health care settings except for patients as required.

Any of your grandparents will have a story about kids who were in school one year and dead the next or a sibling who just didn't make it into adulthood. Our modern age of miracles is exactly that and it is of very recent vintage.
