tnmom··on How to build a $20B semiconductor fab
Who knows - it’s just fake internet points. Hard to get worked up about.
tnmom··on How to build a $20B semiconductor fab
Much of that money goes to permitting, admin, and insurance. What you’re seeing is probably the $10-20 million that wasn’t successfully siphoned off by bureaucrats.
tnmom··on The Hidden-Pregnancy Experiment: Could I Hide My Pregnancy from My Phone?
tl;dr she didn’t send any obvious signals that she was pregnant, and didn’t get any ads. The headline only represents about four paragraphs from a very long article that rambles all over the place.
tnmom··on The drinking fountain button
Just you; in my comparatively sane state most were never turned off and those that were came back within a few months.
tnmom··on You can't just assume UTF-8
Huh, never heard that before. Does it leak more information than just encrypting without zipping? Struggling to imagine how this attack works.
tnmom··on Apple's risky bet on CarPlay
I am _very_ happy that the manufacturer of my car is a subservient cog wrt the infotainment system. They suck at when they’re not a subservient cog.
tnmom··on NASA's Voyager 1 Resumes Sending Engineering Updates to Earth
Good lord could you imagine the meltdown HN would have if Apple had taken this option to solve the old-batteries-support-lower-peak-current physics problem?

“Your device battery no longer supports the camera. Or the backlight on the top third of the screen. But it runs at full speed otherwise!”

tnmom··on How to fix America's aviation system (2023)
What incidents are you looking at that make you think pilot standards are too low? In the US?
tnmom··on How to fix America's aviation system (2023)
ATC is a unique thing - if you’re interested, suggest listening to the https://www.opposingbases.com/ podcast. It’s eye opening how much complexity they deal with, and how frequent the edge cases really are.
tnmom··on Meta says you can't turn off its new AI tool on Facebook, Instagram
Genuine question - why do you allow _any_ time? I don’t have kids, so I’m able to make these large generalizing statements: seems like personal connections to AI chatbots are a form of brain rot.
tnmom··on Tesla recalls all cybertrucks for faulty accelerator pedals
0-60 time is 2.6 seconds, or 10.32m/s^2 if it’s evenly distributed. So from zero you’d be doing 11.5mph in 0.5s (and travelled a little over four feet).

But importantly, it looks like this is more of a ratchet effect… so if your pedal is stuck at 100%, it’s because you pressed it that far (even if intending it to be momentary). That’s not something you’d normally do in a parking lot full of nuns, you’re probably on a highway with some time to react and press the brake. My guess is that’s why we haven’t seen a tragic accident out of this.

tnmom··on Rents Are the Fed's 'Biggest Stumbling Block' in Taming US Inflation
Sure seems like the solution is to get bank money out of housing. I say this as someone who’s usually on the free-market side of debates.

Is there a true downside to the plans occasionally thrown around in Congress to limit/disincent institutional investors housing holdings?

tnmom··on Should Apple Kill Siri and Start Over?
Unless they’re pressing the button on your phone, it’s not an issue.
tnmom··on Should Apple Kill Siri and Start Over?
Yeah, aka evidently the only place that has hardware & software teams good enough to do all this stuff on device.
tnmom··on AWS kills Snowmobile data transfer truck
Cards get declined. Support tickets get created. Customers die and you have to hold all their stuff open for 90 days while trying to reach them, without a chance of getting paid.

You might not be stupid, but there are people who look _just like you_ who will email support over a six cent billing issue which turns out to be correct anyway - but just burned a couple hours of support people’s time.

Epic probably doesn’t do stuff like that.

tnmom··on AWS kills Snowmobile data transfer truck
Because you’re a more expensive customer per dollar of revenue, statistically - there are constant costs per customer for support, billing, etc.
tnmom··on How many bathrooms have Neanderthals in the tile?
Really? As a private person I’d jump at that opportunity.
tnmom··on Careful with That Lock, Eugene
ankane is some kind of superhuman cyborg. Seems like about 25% of the really useful gems I use have that name in the URL...
tnmom··on How Hertz’s bet on Teslas went sideways
Thank you; I didn’t have the time or patience to deal with the “sources” crowd on this one.
tnmom··on How Hertz’s bet on Teslas went sideways
I feel compelled to point out that usually, the story develops the other direction - from:

"Autopilot crashes car, kills family!"

to (with much less fanfare):

"Actually, it was a drunk dude driving manually and wrapped his car around a tree at 120mph in his own driveway"

tnmom··on Receive push notifications from your rice cooker
A Pi draws somewhere under 10W at peak, probably significantly under that most of the time. That’s about 87kWh per year, worst case.

Something like $8-16 dollars depending on how incompetent your power company is - well under the threshold for anyone who knows how to do this kind of work to worry about. Again, worst case; I’d bet you can do constant listening half that.

tnmom··on CA train project needs another $100B to complete route from San Fran to LA
For reference, Wikipedia says SpaceX has spent $3B on the Starship program through May 2023. Another 2B estimated in 2023 at that point, so somewhere less than 10B total, easily.

It went to space today, and these jokers can’t lay railroad track like we did in the 1800s.

tnmom··on EV Charging Points in America Are Finally Making Money
You can charge outside without issues. Snow/sleet doesn't matter; the charging connections are water-tolerant.

And you should probably find some better electricians to get a quote on the home-charger thing - sometimes "I want to put a dryer plug here" gets a lower quote than "I want an EV charger here" (the latter signals money-spending-ability).

Also, do the math on what you really need for charging. Most people can charge at home overnight on a standard 120v outlet just fine - unless you're driving more than ~50 miles a day, every day, consistently.

tnmom··on A 7k-Pound Car Smashed Through a Guardrail. That's Bad News for All of Us
No, liability insurance pays out your _liability_ for pedestrian's medical bills and/or death caused by you. That's the point.
tnmom··on A 7k-Pound Car Smashed Through a Guardrail. That's Bad News for All of Us
Why the downvotes? Insurance is one of very few industries that truly has incentives to price their product correctly. If I can get liability insurance on my Civic for $30/mo, or an F250 for $35/mo, there is a _clear_ incompatibility with the risk level assessed by HN vs. the risk level assessed by professional insurance actuaries with many decades of data.
tnmom··on A 7k-Pound Car Smashed Through a Guardrail. That's Bad News for All of Us
(Nearly?) all states already have liability insurance requirements, and they already scale with real-world injury probabilities.

Those events just aren't as common as HN believes, so the driver of a KillMax HighBumper 9000 doesn't pay much more in insurance than the driver of a Civic.

tnmom··on Cracking Meta's Messenger Certificate Pinning on macOS
Envelope encryption works for that - client generates a random symmetric key, encrypts the data symmetrically, then asymmetrically encrypts just the key (which is then thrown away on the client). Both the symmetrically encrypted body and asymmetrically encrypted key are sent.
tnmom··on AWS acquires Talen's 960MW nuclear data center campus in Pennsylvania
Their marginal cost for you using otherwise-unutilized capacity is near zero; probably just power really. So if it’s a choice between getting $0 and $0.1 for a $1/hr instance, that’s an easy choice.

You just have to be sure to make the spot stuff juuust unreliable enough that people can’t run their full workloads on it all the time.

tnmom··on New 13- and 15‑inch MacBook Air with M3 chip
Probably some vendor provides the trackpad, and provides a driver for that trackpad, and it recognizes the gesture and then sends Windows a `GestureHappened()` event.

Versus macOS being fully integrated and effectively generating `GestureProgress(0.31)` events.

tnmom··on Is Google Making Us Stupid (2008)
Turns out, it was actually the left making Google stupid.
