Yes, you should look up Rice's Theorem.

With cars, it's posible. With complex software it isn't. There's a reason for that.

Yes, one'd have to hard-code it. It's up to the developer to decide what server to hard-code, obviously. Context will tell what's more appropriate, by I'd gess most big projects would use their own servers.

I bet you don't read 90% of what's written on any subject.

No need to make your applications stop working. Just try the default DNS, and if it fails use another server. Also, cache the failure during the session, so the ISP will lose your metadata.

The registart choice is up to you. Just choose one that offers DNSSEC.

The ISP part is harder, but if applications stopped using their DNS when DNSSEC is not available, they would adopt it in a heart beat.

How is referencing some syntax on google any different from referencing something in a book? Apart from the 8 seconds it takes to look it up on google vs. the 38 seconds it takes to look it up in a book?

Unless you have just a couple of books, that'll probably take something in the 90-6000 seconds interval. Also, Google can point you into many more "books" than what fits your bookcase. This is one of those cases where a quantitative difference is so big that it becomes a qualitative difference.

The internet is just a terrible source for up-to-date information.

Wait, what?!?

What better source do you know? Do you know how we used to find up-to-date information before the Internet? We didn't, we relied on months old printed articles or years old books.

Nope, there's no easy way to remove Kerberos dependency on time synchronization.

The only thing needing notice is that Kerberos requires closks to be synced within about a second (could be increased to a few minutes of error easily), while NFS reuires a few miliseconds of error at most.

No idea at all.

I'm calling it Red-Hattitis, expecting it to be a kind of mental disorder. But if somebody does really know what's the cause, I'l love to hear.

RFID is still easier than either OCRng tags or silikscreening QR codes. It lasts way more than the clothes, it can be read on both sides, it's faster to read, and it can be read while wrapped. Also, it can be mass produced, easily fixed, and given a meaning only after the fact.

In fact, I didn't think about peer to peer communications, just broadcasting.

That's easy. If the content is commercial, the cryptographic keys must be either sold or published at some time. Otherwise there wouldn't be any money in there.

An interesting aspect of science is that all our models are always wrong. And we are always aware of that.

I do, but you won't be able to go through doors.

The point of fire drills is to test if your evacuation procedures are fast enough. If people somehow get out faster in a real fire, well, good for them.

What takes us to this article proposal... What's the point?
