etskinner··on Claude in Chrome
Do you have evidence that it saved more people than it poisoned?
etskinner··on This is not the future
Seems like you meant to post this in https://news.ycombinator.com/item?id=46288415 , not here
etskinner··on School cell phone bans and student achievement
Since when are cities banning phones? And how?
etskinner··on YesNotice
I presume most mobile RSS readers do this already. With the added bonus that users can set their own settings of how often to refresh their feed rather than writing a service to do it

etskinner··on Bring bathroom doors back to hotels
You've never seen a sliding door rather than a fully closing one? That's one of the types of doors that the author is complaining about

Parents have whatsapp groups for their kid's classes? That's news to me. When did that become the norm?
etskinner··on FAA to cut flights by 10% at 40 major airports due to government shutdown
In short, horse trading. That is, if you have leverage in an adversarial negotiation, you'd be foolish not to use it to get more of what you want.

For example, as a prospective employee, if I knew that I was the only qualified candidate the employer had interviewed, and they really needed someone within a week, I'd know that I can ask for more salary. If I instead take the middle of the salary range, just because it's maximally acceptable to both parties, I'd be missing out

etskinner··on Passkeys: They're not perfect but they're getting better
Let's assume your vault/login has these properties:

- You have a strong unlock password that you don't use anywhere else

- You have a second factor set up for unlocking the vault (TPM in the device you're using, Yubikey, TOTP, etc.)

- The service you're logging into has good account recovery hygeine

The benefit, assuming those things, is that the passkey is phishing-resistant and social-engineering-resistant. If a user gets an email saying "omg, someone tried to transfer your paypal, click this link to log in", then when they try to log in with the passkey, the site the attacker is using won't be able to use the passkey (because the passkey is associated with a particular domain). Even if the user wanted to bypass this, there's specifically no way for them to extract the contents of the passkey.

That is very different from a user having their password stored in their vault. They could easily forget to check the domain, or get tricked by a very similar looking one, and copy/paste their password into the attacker's form.

etskinner··on Amazon hopes to replace 600k US workers with robots
> Job losses could shave 30 cents off each item purchased by 2027.

I know this is just a start (and just enough to make the ROI worth it, probably), but it sounds particularly dystopian / late stage capitalism

etskinner··on ADS-B Exposed
Apparently my 'easy' isn't the same as yours. There's nothing I could find in the code that describes what it is. You'd have to make a pretty big logic leap to figure it out. All you can see in the code (in config.js, not in index.html) is the dataset url (random string) and the description "this website", which tells you very little.

For anyone who just wants to skip to the answer, I found it in the pull requests / issues: https://github.com/ClickHouse/adsb.exposed/issues/47

What is "You"? I tried reading the query to understand but couldn't figure it out
etskinner··on Macro Splats 2025
How does it capture the reflection (the iridescence of the fly's body)? It's almost as if I can see the background through the reflection.

I would have thought that since that reflection has a different color in different directions, gaussian splat generation would have a hard time coming to a solution that satisfies all of the rays. Or at the very least, that a reflective surface would turn out muddy rather than properly reflective-looking.

Is there some clever trickery that's happening here, or am I misunderstanding something about gaussian splats?

Why is that a problem? Potential for damage when exposed/changed? No battery protection?
etskinner··on Show HN: Burnt US Dollars
They address this on the site:

>bUSD is not a stablecoin. It can never be redeemed for USD, and may trade at values other than $1 for extended periods of time.

etskinner··on Show HN: Small Transfers – charge from 0.000001 USD per request for your SaaS
$0.10 per hour is already WAY more than a creator usually gets from your viewing. I'd happily pay that amount for good youtube-like content. Creators would love it because it's far more money than they get now. Consumers would like it because for a lot of people it's cheaper than a subscription, and they could forgo ads
etskinner··on Zoox robotaxi launches in Las Vegas
I'd argue that tourists are the main untapped market in terms of transportation on the strip. Workers and residents might already be familiar with the public transport that exists, but most visitors would probably rather get a private car at the exact time they need it (going to the exact place they want to go) rather than figure out the bus schedule. That's proven by the fact that lots of people grab Ubers/similar to get around there.

Of all the places to try a gimmick, Vegas is the right place.

etskinner··on Americans Lose Faith That Hard Work Leads to Economic Gains, WSJ-NORC Poll Finds
The article may be referring to page 14, actually.

The question on page 14 is "Do you think the American Dream--that if you work hard you'll get ahead--still holds true, never held true, or once held true but does not anymore?

And the results are (from 2023 to 2025):

Still holds true: 36, 34, 31 (downward trend)

Never held true: 18, 17, 23 (upward trend)

Once held true but not anymore: 45, 49, 46 (mixed trend)

etskinner··on Why do people keep writing about the imaginary compound Cr2Gr2Te6?
It seems like the only reason Gemini knows this is because of the exact article we're discussing. Seeing as it's the first result when you search it, Gemini is just summarizing the article rather than synthesizing the info itself.

etskinner··on Wish you could escape the planet? Too bad life in space would suck (2024)
The title should include "(2024)"

Suni and Butch have been on the ground since March, but the article mentions that "Stranded NASA astronauts Sunita Williams and Butch Wilmore have been living aboard the ISS for 170 days since their departure from Earth on June 5."

etskinner··on Unsafe and Unpredictable: My Volvo EX90 Experience
They'll probably agree on a settlement where they don't admit any wrongdoing and give him a decent payout, but require him to take down the site and sign an NDA or something. So they don't necessarily need to replace all of them after that

If all he wants is a refund, that should do it. But if he's more interested in warning the world, hopefully he sticks to his guns and makes them give a straight up refund

etskinner··on How you breathe is like a fingerprint that can identify you
If you can figure out a way to do without the nasal cannula, the possibilities are huge. Maybe a good IR camera could look at the air coming out of your nose and determine the velocity. Seems like it's actually already a thing [1].

Cynically, you could use it for surveillance, similar to how they do face recognition or temperature scanning in airports.

The flip side of the coin is that it could be used for better authentication or medical purposes. Maybe your oxygen tank could realize you're breathing different than usual to warn you that you might be having a seizure, stroke, or heart attack. Or maybe we'd have "breathe to sign in" similar to FaceID

etskinner··on The scientific “unit” we call the decibel
Here's another related one that always bothers me: When you say something's loudness in decibels, you also need to specify a measurement distance.

The author of this article even accidentally makes this omission:

> It’s 94 dB, roughly the loudness of a gas-powered lawnmower

And that distance is very important; the actual sound pressure measured is proportional to distance^2. So for a lawnmower measuring 94dB, let's say we assume that we're measuring at 1m. At 2m away, the sound is actually 91dB.

And don't get me started about the fact that a halving in power is 3dB, that's just wacky. I wish we used base 2.

etskinner··on Why are banks still getting authentication so wrong?
As far as I can tell, the reason why any given login is needlessly complex is that some product manager somewhere has outdated info in their head that says stuff like "passwords need 4 different character classes" and "everybody uses SMS for 2FA, we need to use that". Powerless devs then mindlessly implement what they're asked to implement.
etskinner··on Dusk OS
You don't need a CD drive to boot an OS. A humble USB stick does the trick. And nearly every computer made in the last 10 years has a USB port and the ability to boot from it
