randerson··on Sonnet 5.5
While I mostly use Opus for coding, I use Sonnet in my actual application, because it is far cheaper at scale. I have Sonnet parse user free-text input, understand it and return the meaning as structured json. It doesn't need advanced reasoning, just a good enough understanding.
randerson··on Bill to Ban Private Equity from Owning Medical Practices
Indeed. But remember a PE firm has economies of scale because they own many vet practices. They can negotiate better rates with suppliers than you can, and better payment terms. Maybe they even own some of those suppliers. They can divide their advertising costs by all the practices they own, whereas you can't.

Even if you were willing to be as ruthless as a PE firm, raising your prices and sacking half your staff, and even if you were somehow an expert in financial engineering and business optimization, you still won't make the business as profitable as they can.

randerson··on Bill to Ban Private Equity from Owning Medical Practices
If you start your own veterinary practice, and eventually build up a steady stream of happy customers, then sooner or later the PE firms will come knocking on your door, too.

Imagine you're drowning in student debt and worrying about keeping your business afloat, when someone offers you $5M, and says you'll still get to work with animals, which you love, while they take care of the financial and business side, which you didn't enjoy. It's a no brainer for most people.

randerson··on Porsche puts wireless EV charging into production
Porsche is famous for underpromising and overdelivering.

For instance they claim a 0-60 time of 2.4s for this car. Car & Driver independently tested it and achieved 2.1s. They also claim 298 miles of EPA range (mixed highway & city driving). Car & Driver worked out 300 miles at a constant 75 mph (which is harder on an EV than city driving.) On the base model, which claims 303 miles range, MotorTrend achieved 350 miles of pure highway driving.

Pick any Porsche and you'll see that they lie to make things sound worse than they really are.

randerson··on NTSB issues investigative update on B-767 runway excursion accident in Miami
In one of the videos you can see dark clouds behind the plane. I suspect the pilots knew they'd have to divert to a different airport if they couldn't land and put pressure on themselves to not have to do that.
randerson··on Muse – Meta’s personal AI agent
The band Muse (who has been around 32 years) just lost their Instagram handle thanks to this..
randerson··on Japan halves speed limit to 30km/h on all narrow city streets
They're old because they didn't get hit by a car.
randerson··on Dr. Melvin Scheinman: 40th Anniversary of Catheter Ablation
Had this done too to cure PVCs - a irregular heartbeat that wouldn't have killed me, but it did lead to an enlarged heart and low energy.

I remember feeling great during the procedure thanks to whatever meds they gave me. I could watch them on a screen threading the wire in through my femoral artery all the way up into the inside of my heart. Then I felt the exact moment I was cured. The irregularity I'd known my whole life just changed rhythm. Then they injected some stuff to stress test the heart at high and low speeds. 24 hours later I was back home.

randerson··on Dimethyl Mercury Exposure Incident at MIT
Good video about what happened to her body: https://www.youtube.com/watch?v=NJ7M01jV058
randerson··on Omarchy: Any User Process Can Escalate to Root
The likelihood of Omarchy being hacked is no doubt compounded by the number of enemies DHH has created who would love to see him fail.
randerson··on Remote workers report the highest well-being in study of 7,700 employees
If you get laid off, it is your personal relationships that will help you land another good job while everyone else is fighting over the scraps that get posted online.
randerson··on California's new tire efficiency rules could save drivers $1B a year
My Mach-E came with CrossClimate2 tires and I am not impressed. I've accidentally lit up all 4 tires under hard acceleration on a dry road, despite 5000 lbs pushing them into the ground and some amount of traction control still active.

I have a lighter sports car making similar power, on Michelin Pilot 4S summer tires. That car just grips and goes with barely a squeal. Good summer tires also have far better wet performance than CC2s, and they provide better feedback.. you feel more planted and in control.

I am impressed overall with the CC2's ability to be a true all-rounder that is usable in snow, but it is still an exercise in trade-offs and it'll never be as good as any purpose-built tire is at its purpose.

randerson··on A Trampoline
In most of the USA getting around by car is mandatory. Trampolines are optional.

Trampolines are one of the top avoidable causes of ER visits.

randerson··on Show HN: Richest people in the world by wealth creation instead of ownership
Though he also eliminated a lot of value for shareholders of World Book, Encyclopaedia Britannica, etc
randerson··on Every new car sold in the European Union must include a driver monitoring camera
My car (from VW Group) came with Active Lane Keep. It detects when you're drifting out of your lane and steers you back into it. Sounds great in theory.

Except that in the US, if you're cruising in the right lane then every time there's an exit it will actively steer you towards the concrete median between the lane and the exit. I don't understand how this feature was signed off on. The risks outweigh the benefits, in my opinion.

randerson··on Google to pay SpaceX $920M a month for compute capacity at xAI data centers
Bonds only give you certainty to the extent that inflation remains certain.

Stocks generally rise with inflation, whereas bonds continue paying out the same nominal amount, which buys you less over time.

As a retiree I'm 50/45/5 in stocks/bonds/cash, having opted for a conservative portfolio. The stocks are the only reason I haven't lost buying power. But the bonds have performed so poorly that I've barely kept up with inflation despite the amazing bull run in stocks.

randerson··on I was recently diagnosed with anti-NMDA receptor encephalitis
As someone who is currently going through the diagnostic process for MCAS with a specialist:

A negative Tryptase blood test doesn't mean you don't have it, it could just be that you're not having an active flare-up at the time. So they also prescribe high doses of H1 and H2 blockers and then you report whether symptoms have improved across 2 or more organ systems after a few weeks.

randerson··on I was recently diagnosed with anti-NMDA receptor encephalitis
90% of EDS sufferers have the Hypermobile variant, for which there is no genetic test. At least thats what I was told by an EDS specialist a few years ago.
randerson··on Cars collect a startling amount of data about you
I requested my personal data from Lexus to see what they had on me.

Not only did they store sensitive data about me, it also included personal data about 2 random Toyota owners who were incorrectly linked to my email address. I could see their full names, phone numbers, home addresses, details about their cars and every interaction they'd had with their dealers. It is a goldmine for a bad actor.

And this is despite me not signing up for "Connected Services", because Toyota/Lexus's privacy notice says they too may sell your location and driving behavior to third parties including insurance companies if you enable features like Emergency SOS.

randerson··on Anthropic Cofounder Chris Olah's Remarks on Pope Leo XIV's "Magnifica Humanitas"
> they remain in important ways mysterious even to those of us who train them

"The AI works in mysterious ways"

randerson··on 2026 HIPAA Security Rule Update
I've implemented PCI-DSS and have 12 years of level 1 audits behind me. I actually find their rules to be sane, pretty good security practice. Internally, we made many of the controls standard across the board even for out-of-scope systems because they were sensible and we'd already built the tooling for it. If you implement it well, once you're compliant it is easy to stay compliant.

And yes, there is plenty of incentive to keep things out of PCI scope. I'd say that is PCI working as intended. Why would you want a larger attack surface that touches your credit card data?

randerson··on 2026 HIPAA Security Rule Update
I've had SOC2 auditors choose a random commit from our GitHub history, then ask to see the associated Jira ticket, logs from the build and deployment, etc. Hard to reliably pass an audit if you don't know which changes they'll drill down into.

They also asked for proof of system-enforced processes (e.g. GitHub branch protection rules and the setting for enforcing peer review for each change) which were basically proof of consistency.

randerson··on Green card seekers must leave U.S. to apply, Trump administration says
I won't defend Biden's weak border, but I don't see any signs that he was specifically letting in people based on their political leaning while excluding others, nor were they given a fast track to citizenship.
randerson··on Rising seas will swallow New Orleans. People need to start relocating now
My insurance agent told me that insurers in the US generally don't cover floods at all, because its expected that your compensation will come from the government.
randerson··on Green card seekers must leave U.S. to apply, Trump administration says
Not just race, but political orientation. Not all white South Africans qualify for refugee status - only Afrikaners. A group who are generally conservative and likely to vote Republican once they've been fast-tracked to citizenship. (English-speaking, urban white people tend to vote more liberal there.)
randerson··on Toxic chemical leak at a manufacturing facility in Orange County
What if built a containment dome and then filled it with cold water?
randerson··on Sam Altman's Business Dealings Under GOP Scrutiny Ahead of OpenAI's IPO
Even if the board votes in favor, wouldn't it be tax evasion to fund a for-profit corporation using a 503(c)(3) - which is tax deductible for donors?
randerson··on New York, California pension leaders oppose 'extreme' SpaceX control structure
> a million people on mars definitely won't be achieved this century, as the place is fucking awful

Mars could make for an interesting prison, though. Like the Australia of two centuries ago. If nobody volunteers to live there I wouldn't put it past Musk to meet his target that way.

randerson··on Dutch suicide prevention website shares data with tech companies without consent
What if the help they need is just to talk to someone without fear of consequences?

If they dispatch you to an institution you could lose your job just when you need money to pay for the bills you'll be sent.

With some careers, like being a pilot, you'd never be be to find another job.

You'd lose your ability to take out life insurance (even if it was a short temporary depression that you got over, like a side effect of a medication, the life insurance companies won't care.)

Or the institution's records could be hacked and you'll live in fear of your friends and family finding out.. which could cause rebound suicidal ideation...

There is no way I would ever call these hotlines unless it were 100% anonymous.
