randerson··on MacBook Pro with PROLED XDR Display and Touch
If you've ever watched a kid try to use a MacBook, they instinctively touch the screen because they were raised on iPads.
randerson··on SIMD-accelerated computer vision on a $2 microcontroller
That insane new Dyson toothbrush definitely. It has on-device AI analyzing 28 fps video from its camera.

randerson··on There's never been a better time to go into math (by: 3blue1brown) [video]
I'm not against technological advancement. But AI is unlike previous innovations. Soon, every scientific and knowledge-based breakthrough could be made by AI. And we're losing something intangible when that happens.

Think of your average Veritasium video. They know how to tell a story about a scientific breakthrough. It always centers around the human inventors. Take the humans out the story and it's less interesting, relatable, or enjoyable. Also consider: why do HNers hate AI slop? If all that matters is the outcome (getting some point in writing), AI does that. I hate slop because it has lost its human touch. I appreciate a result more when its distilled from human effort, and I'm not alone.

I'm not a mathematician so I have no skin in this particular game. I'm a software engineer though, and we've already gone through this. I can simultaneously love how easy it is to build applications with AI, and miss the days when human talent was valued and celebrated in my field. My job gave me purpose. My work team had comaraderie. A future where we all report to AI managers and we exist just to sign off on what our AI agents do, is dystopian.

Yes, I suspect there will always be human sports teams, musicians, actors, etc. My point was to illustrate that everything is less appealing when you take the humans out of the picture and I don't see why science is different. If outcomes are the only thing that matter then when robots are better at sport than humans shouldn't we should all just watch robots compete?

P.S. Do you really believe humans are going to visit any object further than Mars, let alone actually colonize them? Things would've had to go very wrong on Earth for that to happen, and that future doesn't appeal to me one bit. Call me a luddite if you want. How many people would willingly say goodbye forever to the wonders of Earth so that they can start their family on an inhospitable planet where they'll be indoors for the rest of their life? And why even bother exploring those planets? We can get all the data we need from autonomous spacecraft. Isn't that the outcome that matters?

There is more to life than outcomes.

Would sports teams have as many fans who enjoy their games, if all the humans were replaced by robots? Your team may win, so I'm sure you'll be happy with the outcome, but maybe something got lost?

I for one have always felt inspired when reading about remarkable human achievements. To think that those might be coming to an end, replaced by AI, takes the humanity out of those stories.

randerson··on Gemini 4 Argon
I recently tried to create a new Gmail account for a small app I've made. I wanted a way for users to get hold of me other than my personal email address.

They now ask for your mobile number during signup. And it wouldn't let me register any more accounts with my number. So frustrating.

randerson··on New gTLD Application for .lan
If you care a lot about home network security: spend $12 and buy a domain name for your home network. Your DNS entries can still be on your local DNS server. You can have HTTPS certificates without warnings, and there's no risk of someone else registering the domain and your requests going to an outside IP.
randerson··on Man discovers his parents' coffee machine used 1TB of data in 10 days
It's not enough to simply have a IoT VLAN that you put all your IoT devices on. Because those devices can see one another. In this case, if the coffee machine can see what type of smart fridge and smart toaster you're using, they can sell that data.

I default to adding IoT devices to a 2.4g "Guest" network where they can't see each other. Exceptions are IoT devices that need to see their friends to do what I bought them for, or devices I want to integrate with HomeAssistant. In those cases I create a separate IoT device per IoT brand. Excessive but necessary.

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 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 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.
