Here's a page where you can test your hearing at high frequencies. (Scroll down a few screens.) I stop around 14,000. No idea if that's good or bad. The kids claim they can hear all the way to 20,000!
In our case the answer is no but, damn.
And as long as I'm linking to disturbing stuff, here are some guys who are running for Congress and apparently have a decent shot at winning. I truly don't know what to add here.
On a more cheerful note, here's some science. So there are two pre-signalling waves: one about fifteen minutes in advance and one about fifteen minutes in advance and another about forty seconds before. Every parent knows about the second one -- it's when they get that glassy-eyed look -- but the existence of an earlier signal is interesting.
Quality video games for free: has anyone tried this or, more correctly these? Are any of them kid-friendly?
And speaking of art, this guy turned some 200+ year old prints into modern photographs. (Slightly NSFW.)
Via Noel's blog, I really like this paper (.pdf) on the economic impact of black disenfranchisement after Reconstruction. (There's an alternate universe where Marx was an economic materialist, but neither a revolutionary nor a Hegelian, and we started doing stuff like this a hundred years ago. Well, at least we're doing it now.)
Most of these link-roundups contain a special link for nerds or geeks. This is that link.
Finally, this is an interesting idea (.pdf): have poverty professionals periodically spend some time in actual poverty. FWIW, I self-identify as a development professional, which is a slightly different thing. That said, this doesn't strike me as an inherently insane idea. Idealistic, definitely; probably pretty uncomfortable in practice, and so very unlikely to catch on. But... well, interesting to think about.
