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.

I remember being shocked at the time that he had the foresight to use Tor but not to use literally any wifi network other than the campus wifi. That being said, there are a whole list of things he'd have to do to keep anonymous and it only takes one slip to identify someone.
