>How much energy does a car factory use? What about a chip fab? A hospital? A battery manufacturer?

tl;dr: rough napkin math and basic googling, 20 MW for a car factory, 100 MW for a chip fab, 2 MW for a hospital, and 0.2 MW for an apartment the same size as the data center. Water usage is equivalent to 14 car factories, 52 hospitals, or 18,000 people at home.

Good questions! You made me curious. In the process of looking, I came across this[0] reddit post with a chart comparing various industrial uses. For car assembly specifically, Honda has some nice global data here[1], and their total energy consumption is about 990 MW, split roughly equally between direct and indirect consumption. That's split across something like 60 factories! If I just look at direct energy consumption, that's less than 20 MW per factory.

This[2] has a chip fab at 100 MW. This[3] has an average hospital at 1.7 MW, with the largest use just being heating. I didn't try to look up battery manufacturers. This[4] has a typical apartment at 0.77 W/square foot, which would mean just 0.2 MW for an apartment the same size as the data center in the article.

I think a more interesting distinction is water usage. The linked article says that the Fireball LLC datacenter used 548 megagallons of water in 2025. Assuming that aligns with the "water consumption" rather than "water withdrawal" numbers from Honda, that's over 20% as much as the entire global operations of Honda equivalent to 14 factories (adjust by about a factor of two if we should be comparing to water consumption). Alternatively, it's equivalent to 52 hospitals[5] or 18,000 people in their homes[6].

You had me curious about what I was tested for, also in the northeastern USA in the 2010s. It looks like they included Hep C when my PCP ordered STD tests in 2015, along with most of the tests the other commenter mentioned. I'm glad they caught yours in time to treat it well!

Merchants often pay a chargeback fee on top of refunding the main charge. Additionally, merchants with lots of fraud or other chargeback issues are likely to be dropped by payment processors or see their general fees with payment processors get more expensive.

I suspect this is a real problem for charities, though. If those bots are using stolen credit cards, the "donations" are going to cost the charities money after they pay extra fees to the credit card processors. Nonprofits are sometimes used to test stolen credit cards before making more profitable fraudulent transactions, so there's a real risk of it costing them money if they get rid of the captcha but don't replace it with something sufficiently high quality, even after accounting for the occasional lost donation.

This also requires knowing how much it will shrink, and accurately gauging if I've left enough buffer when trying something on at the store.

Wikipedia has some notes on why least squares, and how you might get there from other assumptions: https://en.wikipedia.org/wiki/Least_squares#Statistical_test... .

Also, quadratics are just much easier to work with in a lot of ways than higher powers. Like you said, even powers have the advantage over odd powers of not needing any sort of absolute value, but quartic equations of any kind are much harder to work with than quadratics. A local optimum on a quartic isn't necessarily a global optimum, you lose the solvability advantages of having linear derivatives, et cetera.

I feel like there's a bit of a jump from "tech-savvy" to de-soldering things on an expensive piece of home electronics. As it stands now, though, I agree that turning off the smart TV features seems to be the way to go for most people.

Troy Hunt has been running Have I Been Pwned for years. He even uses the k-anonymity model to allow you to search if a password has been pwned without giving him the password if you don't trust him.

I get your general point, but he's been a leader in this space and walking the walk for a decade. I'm not even into security stuff or anything particularly related to this, and I still recognized his name in the OP domain.

I enjoyed reading the article, but I'm pretty thrown by the benchmarks and conclusion. All of the times are reported to a single digit of precision, but then the summary is claiming that one function shows an improvement while the other two are described as negligible. When all the numbers presented are "~5ms" or "~6ms", it doesn't leave me confident that small changes to the benchmarking might have substantially changed that conclusion.

Thank you! You're right that's the sort of "hacked together" solution that looks cool but beyond my abilities, and I appreciate the first two links.

Can you link an example of a window unit ERV? I tried searching briefly, and came across some folks hacking together units to make them work with windows or adding their own ducting, but nothing analogous to a simple window air conditioning unit. As a renter of an apartment in a very much not modern home, I don't really see anything that seems like it would work.

That makes sense along the lines of their second proposal, but doesn't address the concerns of the first. Part of democracy means voting for the folks who govern you, but a prisoner might be left unable to vote in an election for the local state or municipal governments.

>2) It's just generally good to diversify into your competitors. Every company does this, especially when the price is cheap.

This definitely isn't a thing that every company does (or even close to every company).

> What’s Apple’s default time frame for security support?

This isn't thaaaaat far out of support. Their last security update for iOS 15 was just earlier this year, and they only dropped iPhone 6s from new major versions with iOS 16 a few years ago. As someone who has kept my last few iPhones for 5+ years each, I definitely appreciate that they keep a much longer support window than most folks on the Android side of things.
