Excerpt from :

this claim is always funny for 2 reasons — (1) you can’t pick a non-quantitative profession in the world more explicitly didactically trained in bayesian stats than physicians, (2) you can’t pick a group of people more interested in low PPV tests (MRI/labs/etc) than Bay Area tech

Password rotation or Forced changes lead to "password hedging," where users just add a number or change one letter (e.g., Summer1! becomes Summer2!). It is biologically impossible for most people to memorize a high volume of complex, random strings every few months, leading to "sticky note" security risks. When security is a hassle, users find dangerous shortcuts, like reusing the same "strong" password across every site they own. The most important fact is that NIST (National Institute of Standards and Technology), the global authority on cybersecurity standards, officially retired this method In its Digital Identity Guidelines (SP 800-63B), NIST now explicitly states that organizations "SHALL NOT require" periodic password changes. They’ve shifted the focus to Length over Complexity. They recommend allowing passphrases of up to 64 characters and only requiring a change if there is actual evidence of a compromise.

This is, imo, the most achievable and best singe answer to this question as well. the local municipalities issue is probably our single greatest. it holds back immense economic growth and general societal development. x.com/bulkingtonbook…

@captgouda24 @sarthakgh Long term care hospitals take care of far different patients than SNFs or SARs. Not comparable.

Wanna save Medicare $4.6 billion a year at no harm to the patient? Stop reimbursing long-term care hospitals three times as much for the same care provided as nursing homes! What was created as a regulatory carve-out in the 80s has grown into hundreds of wasteful hospitals. 1/

Yesterday I spent more time helping patients figure out how to pay for their medications than discussing their actual medical concerns. This is how the souls of physicians die. Not all at once, but one paper cut at a time.

Austin tried to pass rent control, but the state didn’t allow it. Instead, we allowed developers to build. Now it’s cheaper to rent in Austin as a % of income than in decades. Move to states and cities that build things instead of having virtue signaling policies that don’t help

@AnilMakam They are paying for it

provocative question in isolation. but then raises the questions, should residents and fellows pay for the teaching, mentorship, liability, and access to patients during training as non-licensed doctors?

Fluid restriction in patients with heart failure: a systematic review heart.bmj.com/content/early/…

Whenever you see a contextless large number you should be pretty skeptical. My hometown of 17,000 people uses 1.5 million gallons of water per day. Enough for 21 data centers like this. If you saw someone saying that the American west cannot afford to have 17,000 more people move there I think you'd be a little suspicious. Irrigated alfalfa farms use about 3-4,000 gallons per acre per day, and there are 6 million acres of irrigated alfalfa in the west. That one crop (which mostly goes to feed livestock) is using as much water as 500,000 data centers at this size. Data centers are always going to basically round to zero on the list of the west's water issues.

LASIK eye surgery cost $2,200 per eye in 2000. Today it's around $1,000 per eye despite 24 years of inflation. Meanwhile, an MRI that cost $1,200 in 2000 now costs $3,000+. The difference? LASIK operates in a free market with no insurance interference and minimal regulation. When patients pay directly, providers must compete on price and quality. LASIK clinics advertise prices, offer financing, and constantly improve technology to attract customers. Compare this to hospital procedures where prices are hidden, patients never see bills, and insurance companies negotiate opaque rates that somehow always increase faster than inflation. Cosmetic surgery follows the same pattern. Breast augmentation, rhinoplasty, and other elective procedures have become more affordable and safer over decades. Surgeons invest in better techniques and equipment because they must satisfy paying customers, not insurance bureaucrats or hospital administrators focused on maximizing reimbursements. The lesson is clear: remove third-party payment systems and excessive regulation, and you get Austrian economics in action. Prices fall, quality rises, and innovation accelerates. Healthcare costs aren't rising because of aging populations or new technology—they're rising because we've destroyed the price mechanism that makes markets work.

Imagine whatever your job is. Now imagine someone who has never actually done that job designs the software you are required to use to do it. Every single task now takes an extra 50 clicks. Things that could be handled with a quick verbal order now require logging in, navigating slow pop up windows, and clicking through reminders that add nothing to the outcome. Now imagine your inbox fills with several hundred notifications a day. Most are useless. Buried somewhere in there might be the one message that actually matters. When you want a simple improvement to the system, you are told it has to go through layers of committees and governance meetings, only to be denied. Yet when an administrator wants to add 20 more clicks or a new mandatory alert, there is no requirement to ask the doctors and nurses who actually use the software every day. That is what is wrong.

A very important imaging study, which a substudy of POET trial, on residual vegetations after non-surgical treatment of left-sided endocarditis. At the end of antibiotic treatment, more than half of patients have residual vegetations on TEE. Among these patients, most vegetations are unchanged in size compared to initial TEE. More importantly, neither the presence nor size of the residual vegetations is associated with adverse outcomes, including embolic events, up to 4 years. jacc.org/doi/10.1016/j.…

@CBSSportsCFB @bmarcello This is the single dumbest and most incompetent ranking I have seen in my entire life, in any sport.

This is obviously not sustainable for the city

“Nearly 80% of the city’s property taxes go toward pensions” Not exactly an unknown stat but it really is shocking every time you see it
