That's only because there is no largest prime number. It's trivial to factor any prime number. The tricky part is proving that a number is prime.

I replaced my Galaxy Tab S6 with an S10 Ultra, and the new one is just too big for my druthers. I didn't realize that it wouldn't fit as well in places like my backpack's tablet pouch, and it's heavy. The pen might be good for some users, but I haven't found a place that I would use it.

On the plus side, windowed apps seem theoretically nice, although I haven't yet used them in anger.

It usually is possible to issue a chargeback. It might take some work on the customer's part, but it will get a lot more attention from the vendor than a customer who ghosts them.

The Apple App Store takes a similar slice of revenue and has a much smaller addressable market -- including just about none of the high-end gamers, given that current Macs are stuck with whatever GPU is built onto the CPU. "Might" is doing an awful lot of work in your comment.

Well I *meant* to post as AC. I'll have to apply those mod points elsewhere :( ... and ironically Slashdot is throttling me, for reasons unrelated to whether my ISP uses CGNAT.

Can you elaborate on #2? In principle, an IPv6 firewall / stateful router can protect devices on the LAN by essentially using NAT logic except for rewriting addresses, right? Assuming that a more naive approach of blocking incoming SYN packets by default isn't good enough, at least.

(Posting as AC so I can moderate up some deserving comments below.)

The problem in this case, as usual, was lazy government rather than big government. A government with high capacity to get things done is not necessarily bad, but usually government turns into a power trip or a mire of reasons that things cannot be done -- and big or effective government is bad in both of those cases.

Did TFA explain why the mother didn't get a court to order her ex to transfer the parental role to her? There are decades of precedent about how to have courts sort out custody disputes and to deal with people who won't cooperate. As an added benefit, it is almost entirely independent of the account provider -- it will work for Apple, Google Samsung, whomever.

Sure, if by "evidence" you mean simulations of a two-seller market where one of the two sellers in a market has a strategy that is essentially only flipping a coin.

This is evidence about the sorry state of economics research much more than about the real world.

2K and 1080p are the same resolution, but 2K -- like 4K and 8K -- is an approximation to the horizontal resolution, whereas 1080p is a combination of the vertical resolution and the scan mode (progressive scan rather than interlaced).

720p: 1280x720, 1080p or 2K: 1920x1080, 4K: 3840x2160, 8K: 7680x4320.

Sure, but their calculation was that a 4K screen is sharper than human eyes can resolve for a 44" screen at 2.5 m (8.2 ft) away. A hypothetical 2K 44" screen needs to be 5 m away in order to give the same number of pixels per degree (PPD) -- and most people are not sitting 5 m away from their TV, especially if it's 44" diagonal. 65" screens are pretty cheap nowadays, and a 50% increase in diagonal size would translate to a 50% increase in viewing distances to get the same PPD.

Their online calculator makes it clear that a 2K 44" TV at 2.5 m is limited by the screen rather than a typical viewer's eyes -- so the Slashdot headline is a lie.

I noticed a rash of these in my spam box a few days ago. The email bodies had lots of fixed content that made it pretty clear that some support system was getting abused, but it wasn't obvious exactly what the cause was.

https://algassert.com/post/250... addresses the case of 21.

https://arxiv.org/pdf/1903.007... seems to be the paper about 35, although it says that noise meant that "the algorithm fails to factor N = 35" (and didn't do a great job for 21 either).

More specifically, digital quantum computers have factored 15, 21 and 35 -- but 15 is a near-trivial special case, and the circuits for the other two used shortcuts that were associated with knowledge of what the factors (of 21 and 35) are. The circuit for 35 can't factor 21.

Almost all US healthcare spending is by the government. And the US government spends more per person on health care than any other country spends government+private. By a lot.

A large majority of that government spending is direct spending on Medicare and Medicaid, not subsidies for insurance. So when you complain that the US "doesn't even have a functioning healthcare system", the most obvious reason is because our governments have broken the system.
