Hello from the former home of the entity referred to as The Ten Thousand Dollar Cat.

There is a filthy joke in Act 5 of Henry V that, despite being a semi-major in Shakespeare, I never got til I saw Emma Thompson perform it in Kenneth Branagh’s movie of same. I howled.

“Schumer did it” is the new

BRENNAN: CBS confirmed the Trump administration rescinded the layoffs of CDC scientists. Some were involved with the federal measles response. How does a mistake like this happen?

VANCE: The govt shutdown inevitably leads to some chaos. It happened because of Schumer

B: But this was a WH decision

Thank you for standing up for adverbs, I love them so.

Unlawfully fired from your job at HHS or CDC protecting the public health? Want to talk through how to tell your story in the press? I'm happy to help you think through messaging strategy.

I’ve spent years doing public health comms and talking with reporters. You can see my work at matthewcort.land

This is what Catholicism is for, and that this is happening in the hometown of the new pope is not incidental.

Chicago priest Fr. Larry Dowling describes procession to ICE facility: “No one had the courage to speak directly to us. No one from Homeland Security could stand in the presence of the Monstrance holding the Blessed Sacrament. No wonder. Evil is repelled, recoils in the presence of Christ.”

Some of last night’s CDC bloodbath being reversed? What an absolute cluster. But great breaking reporting by @jeremyfaust.bsky.social

open.substack.com/pub/insideme...
“Some of the reversals came after the Trump administration realized that they had accidentally terminated critically important staffers working on current measles and Ebola outbreaks.
A former CDC official was told that HHS communications officials were not happy with the media coverage of the RIFs, and may have felt that the move reflected badly on the administration, as outrage and accusations that the administration was using the government shutdown as a pretense to accomplish other political goals seemed to be sticking.”

I'm extremely interested in this effort! Best of luck.

Measles is back — and hitting schools hard.

Hundreds of U.S. students quarantined amid measles outbreaks
At least 270 unvaccinated kids are staying home from school as measles continues to spread nationwide. "Expect more," one expert said.

"Pontiac fever" in 1968, later found to be an early appearance of Legionnaires disease (not named til 1976); "Four Corners disease" in 1993, later understood to be hantavirus erupting under new environmental conditions.
MMWR rapid-reaction reports have been crucial for guarding public health.
Welp.
marynmck.bsky.social
Reacting too fast, should have said "including when it announced," not "since," because the MMWR has carried many notices of outbreaks that later were back-identified as early appearances of organisms that subsequently caused significant epidemics. Examples: ->

Worth noting that for more than 24h, since plans for RIFs began circulating, legal scholars have been saying that a shutdown conveys NO authority to the White House to conduct firings at agencies.
Illegality has not stopped this administration in the past months ofc. It apparently has not tonight.
marynmck.bsky.social
Extremely bad news if true (and unlikely this reporter would run with it if not). The MMWR has been the earliest warning bell for outbreaks since it announced the first US cases, in 1981, of what was later identified as AIDS.

This will be a grievous shock to what remains of US public health.

BREAKING: Friday night massacre underway at CDC. Doznes of "disease detectives," high-level scientists, entire Washington staff and editors of the MMWR (Morbidity and Mortality Weekly Report) have all been RIFed and received the following notice:

Every single AI data center is a toxic investment, with most of its value tied up in GPUs that will be multiple generations behind by the time these things turn on - and then die in 3-5 years.

All to build for AI demand that doesn't exist.
edzitronswheresyouredatghostio.outpost.pub/public/promo...
Actually, wait - how long do GPUs last, exactly? Four years for training? Three years? The A100 GPU started shipping in May 2020, and the H100 (and the Hopper GPU generation) entered full production in September 2022, meaning that we’re hurtling at speed toward the time in which we’re going to start seeing a remarkable amount of chips start wearing down, which should be a concern for companies like Microsoft, who bought 150,000 Hopper GPUs in 2023 and 485,000 of them in 2024.
Alright, let me just be blunt: the entire economy of debt around GPUs is insane.
Assuming these things don’t die within five years (their warranties generally end in three), their value absolutely will, as NVIDIA has committed to releasing a new AI chip every single year, likely with significant increases to power and power efficiency. At the end of the five year period, the Special Purpose Vehicle will be the proud owner of five-year-old chips that nobody is going to want to rent at the price that Elon Musk has been paying for the last five years. Don’t believe me? Take a look at the rental prices for H100 GPUs that went from $8-an-hour in 2023 to $2-an-hour in 2024, or the Silicon Data Indexes (aggregated realtime indexes of hourly prices) that show H100 rentals at around $2.14-an-hour and A100 rentals at a dollar-an-hour, with Vast.AI offering them at as little as $0.67 an hour.
This is, by the way, a problem that faces literally every data center being built in the world, and I feel insane talking about it. It feels like nobody is talking about how impossible and ridiculous all of this is - it’s one thing that OpenAI has promised one trillion dollars to people - it’s another that large swaths of that will be spent on hardware that will, by the end of these agreements, be half-obsolete and generating less revenue than ever.
Think about it - let’s assume we live in a fantasy land where OpenAI is somehow able to pay Oracle $300 billion over 5 years. Said money is paying for access to Blackwell…
