This isn't limited to fake copies of books which are legitimately listed on Amazon, either. About a decade ago I found my doctoral thesis available for sale on Amazon -- with someone else listed as the author.

This ruling probably doesn't cover 100% fully artificially generated stuff. Not this ruling but others do. In 2008 an Australian man was convicted of possessing child pornography for having sexually explicit depictions of characters

I'm not the right person to ask about this, but some ARM systems definitely have weaker coherence than x86 -- in FreeBSD we have a whole bunch of memory barrier primitives which compile away to nothing on x86 because they exist only fo

if you can share memory somehow, you can use a futex. If you can share memory and you have coherent caches you can use a futex. (In particular, many embedded systems have weaker cache coherency than x86, so "it works on my laptop&

'Virus' is a neuter second-declension noun Citation needed. As far as I'm aware, there is no classical attestation for either second or third declension.

One interesting example from Latin is the word "virus", which roughly means "slime" -- being a mass noun, it has no classically attested plural. I think that if it had a classical plural, it would be virora (like corpu

If you want to scan the entire organism, sure. But higher resolution MRI can also mean "scan a smaller part, with good detail, in the same amount of time". I could imagine this being useful for e.g. getting a high resolution ima

As far as the startup process is concerned, SMT is two CPUs. I don't actually know how SMT works when one "CPU" has been started and the other hasn't... I guess it just pretends that it hit a hlt instruction on the unst

Another fun thing with SMP: The x86 multiprocessor spec says that to start an AP you need to send an IPI, wait 10 ms, then send another IPI (IIRC it's a "reset" followed by an "init"). On large systems, this adds u

Thanks for the clarification! The story I was taught (up to and including a graduate course on relativistic quantum chemistry!) is "delocalized point particle", i.e. it's a point but of course for quantum mechanical reasons

He's indicted, not convicted. "I'm a sucker and didn't realize what was going on" is absolutely a possible defense; I would assume that the DOJ will lead evidence to show that he knew what was going on and willingl

Can someone tell me what version of "shape" we're talking about here? I thought electrons were point charges.

Ironically, in Canada the same "must be reasonable" applies but for the opposite reason: The government doesn't want business owners "hiring" family members and overpaying them, since typically employees pay less ta

I used to joke that the government should have a celebration of centenarians and see how many of them actually show up. IIRC a version of this happened a while back in Japan; the mayor of a town decided to visit some of the oldest residen

I think my answer to this would be "thanks for preserving this for us; we're ready to take it back now". These artifacts absolutely belong to their countries of origin, but we have a collective duty to ensure that they are p

I don't know about the USA, but in some countries you can claim a "reserve" for accrued but unpaid amounts in some circumstances. Worth talking to an accountant to see if that's a thing in your case. (Note, there'

It hasn't disappeared from my memory! There were people who did very, umm, "creative" things with S3 (classic example, creating a virtual disk by storing each 512-byte sector as an S3 object) who suddenly changed direction a

S3 prices increased dramatically for some workloads when AWS introduced per-request fees. Admittedly that was a very long time ago, but it has happened.

Usually auctions have some sort of deposit requirements, but where large companies are involved it's sometimes just "show us that you have at least $X in the bank" (cash or treasuries or similar) on the theory that they can b

I know a lot of doctors recommend ibuprofen over aspirin because ibuprofen is perceived to be a safer NSAID. I'm not sure if it's actually safer in adults or only in children though.

Looking at their corporate filings, it looks like between Dec 31 2021 and Dec 31 2022 Amazon sold off about half of their "marketable securities". I don't know exactly what those were, but that sort of change makes me think

Harvard takes in a lot of students on the basis of athletics, legacy, and other non-academic considerations. While I've seen students admitted to specific colleges in Oxford due to family ties, that has always been a matter of which

Yes. I think the top 1/3 of Oxford undergrads are on par with the top 5% of Harvard undergrads. This is not true of other places which award Firsts.
