Everybody knows roads and bridges build and maintain themselves.

I've used a lot of thinkpads over the years, and long before Lenovo took over the quality was pretty mixed. It seemed that they alternated between good/great and terrible. I had one about three years ago which overheated horribly, and the wireless flaked out every time I unplugged it. I had another where the hinges attached to the screen just worked their way free from the body from opening and closing it once a day. The current one (a few years old now) is decent.

Which is why Hamlet and King Lear, among other plays, are thought to be reworkings of older plays.

At the time England didn't have copyright laws. They did have the Stationer's Company, which was the printers' guild. In theory once a printer entered a work into the Stationer's Company Register, other printers weren't able to print a copy of that work. In practice, this wasn't well enforced, and publishers often printed works registered to other printers. The first actual copyright law didn't come until the 18th century.

I think you're missing the point of the article. It's not the age of the finding, but how they did it. As it says in the article, "it's impossible to know whether we have found a Bedouin structure that was made 150 years ago, or 10,000 years ago" without actually going there.

Which is why OSPFv3 is used with IPv6.

Let me change one word in your first sentence (in italics):

Which was very true when the army was first integrated, and it's still true today. Many of those people were in the army then, and some of them still are.

The army survived integration, though, and it's fine. It'll survive the end of Don't Ask Don't Tell, and it'll still be fine

Too late.

The Sumerians, the Hurrians and the Elamites want to have a word with you. (None of their languages were remotely Indo-European, but they weren't Semitic, either.)

I'm obviously not the OP, but sometimes you need a day job in order to chase your dreams.

If they're disorganized enough to accidentally put a server behind a wall, why do you think it's going to be easy to trace a cable? I bet the cabling in that place was an adventure.

Let's suppose there is life on Mars. We can get a pretty good idea of whether or not it's related to life forms on Earth by examining it and seeing how close it is to organisms here. If it has DNA, we could sequence it.

For instance, suppose it looks a lot like terrestrial bacteria, it has DNA, and its genetic code is nearly identical to or very similar to specific terrestrial bacteria. Then yes, it probably came over as contamination.

Suppose it uses DNA, but it doesn't remotely resemble any living bacteria. This may indicate that it evolved from terrestrial bacteria that came over earlier (i.e., hitched a ride on a meteorite). Or that terrestrial life evolved from a hitchhiking Martian bacteria.

Suppose it uses a slightly different DNA system than ours. For instance, the bases may be slightly different, or it uses only RNA, or something along those lines. Depending on the level of the differences, this could indicate that it evolved independently from terrestrial life, or that it hitchhiked over very early in the development of life.

Suppose the Martian organism doesn't use DNA at all. This may indicate that it's completely independent of terrestrial life. That's assuming that life on Earth always used DNA (or at least RNA), which isn't necessarily true.
