Difficult when the options are Medium and Large!
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.

I haven't dealt with statistics for a while, but what I don't get is why squares specifically? Why not power of 1, or 3, or 4, or anything else? I've seen squares come up a lot in statistics. One explanation that I didn't really like is that it's easier to work with because you don't have to use abs() since everything is positive. OK, but why not another even power like 4? Different powers should give you different results. Which seems like a big deal because statistics is used to explain important things and to guide our life wrt those important things. What makes squares the best? I can't recall other times I've seen squares used, as my memories of my statistics training is quite blurry now, but they seem to pop up here and there in statistics relatively often, it seems.
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.

For the tech-savvy, I'm not too worried about smart TVs. I just do this:
> If you want premium image quality or sound, you’re better off using a smart TV offline.
In the future, if they add e-sims, we'll just remove them or de-solder or whatever.
The real risk is cars: if they start not working without cell network connections.
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.

A couple examples I see on Google. I'm not advocating for any of these, because I have no idea if they are any good, but I see no technical reason an ERV couldn't work as a window unit. Maybe it's an underserved market and someone should make a business out of that.
A much more DIY example that's probably closer to what you were talking about with "hacking together" a solution: https://www.mychemicalfreehouse.net/2023/10/window-mounted-p...
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.
Outside air isn’t a panacea. There is often plenty of pollution right outside your window unless you live on an idyllic beachfront property. The humidity level outside is also rarely what you want in your home, whether it is too high or too low.
Much better than cracking a window is the use of ERVs (energy recovery ventilators) and air filters on the incoming air.
An ERV is a fairly simple device that exchanges air with the outside while mitigating the loss of energy and humidity.
Any modern home build likely has an ERV as part of the design, but it’s not like they can’t be retrofitted, and I’ve even seen some DIY-friendly window unit ERVs (but I’ve never heard if those are any good).
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.

You could also just use the last place they lived in before prison.
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.
The reason why Nvidia is buying now does not have to do anything with Arc or GPU competition. There are mainly two reasons.
1) This year, Intel, TSMC, and Samsung announced their latest factories' yields. Intel was the earliest, with 18A, while Samsung was the most recent. TSMC yieled above 60%, Intel below 60%, and Samsung around 50% (but Samsung's tech is basically a generation ahead and technically more precise), and Samsung could improve their yields the most due to the way set up the processes, where 70% is the target. Until last year, Samsung was in the second place, and with the idea that Intel caught up so fast and taking Samsung's position at least for this year, Nvidia bought Intel's stock since it's been getting cheaper since COVID.
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).

> Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals.
Even if there was no mention of this or the implication that it’s linked to the notifications Apple sends for targeted attacks, is it fair to say this kind of backdated security patch implies a lot about the severity of the vulnerability? What’s Apple’s default time frame for security support?
> 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.
