One thing not addressed in the linked article is how broadly “professor” is defined. For example, the researchers say that most sociologists are liberal, and most doctors are conservative, but they don’t mention the politics of professors at medical schools.
Similarly, do their conclusions apply to professors of engineering or management? It seems plausible that business faculties would tend to match the politics of other businesspeople, or that the jobs would appeal to the same sort of people who like the idea of being professors in other areas.
It’s easy to assume professor=liberal arts professor (where math might count, science probably doesn’t, and engineering almost certainly doesn’t).

There’s always a tradeoff between security and inconvenience: it’s easier to walk through an unlocked door, including my own front door while I’m carrying groceries. So it only makes sense to lock a door if you care who comes through it. (You might _close_ a door to keep the wind out, or animals in: the local dog run uses gates that almost any human would find trivial, but the dogs can’t open.) And the more passwords I have, the more I have to either remember or store: and pieces of paper can be lost or stolen.
I leave my work computer logged in to the library’s website, because the worst any of my coworkers could do is cancel my holds on library books; it’s not a real risk. (They could also reserve books I didn’t want, which I wouldn’t have to borrow, or renew the books I have checked out, which is harmless.) That doesn’t mean I’m staying logged in to my personal email, or my pension fund.
Tacroy is absolutely right about hash functions: that was old news in the 1980s. It’s not an absolute guarantee–given a system, a hashed password file, and time, brute-force attacks are useful–but it’s still worth doing.

Brian: Absence of evidence is not evidence of absence. Note that the archeologists who found this weren’t looking for it, because they didn’t expect to find any remains that old. If you are sure that there was nobody living on, say, Sardinia or Cyprus or Mytilene before about 10,000 BCE, and your excavations on a site in the Mediterranean find nothing interesting down to a layer earlier than that, you’d probably stop and dig elsewhere.
This would be the earliest known human (or even hominid) sea-faring, but the other early dates aren’t from the Mediterranean: as the linked article points out, Australia was settled around 60,000 BCE, and there’s no way to get there except by water. And there’s H. floresiensis: whether or not they deserve to be counted as a separate species, there are artifacts there that pre-date the settlement of Australia. So, we know H. sapiens could travel by sea that far back; the question is how many did so, how they did it–what sort of boats or rafts they were using–and how often, and whether they settled there and left descendants. If the travel was accidental, they might be more likely to try to get back to Africa from Cyprus than to try to get back to Asia from Australia.
