Cool thing of the week, round 1

As suggested by Abe, I will start posting a cool thing once a week, with arbitrary regularity. This week, it is the List of common misconceptions. There are some interesting things in there - for example, "eyestrain" from reading in low light or playing video games does not explain myopia. Also, black holes do not somehow develop a stronger gravitational field than the stars that formed them. If our Sun was immediately compressed into a black hole, it would have the same mass as it did beforehand, and (hypothetically) the same centre of mass; the Earth would continue to go around it as normal, only without the usual sunlight. (This also explains why the miniature black holes theorized to form at the LHC are not a threat to the planet. You can look up Hawking radiation if you want more information about why they're not a threat.)

I feel that hoarding "cool things" so that I'm assured to have something each week would be silly - I'd rather post everything as I find them and force myself to find something else cool if I run out. On that note, I've been meaning to set up a Subversion (SVN) server for a while now, to take care of versioning schoolwork and my programming projects. This past week at work, I got started setting one up for the job - it turns out it's much easier than I've been expecting, and I'll definitely be using it from now on. The Wikipedia article might be a little technical for you, but it's really cool stuff. Some people say that even artsies should use it to take care of their papers and so on. I'm personally using TortoiseSVN (a Windows shell extension standalone SVN client); I think Visual Studio 2008 probably has its own built-in plugin, so I'll be seeing if that connects to my server as well. If you're one of my less-technical friends, and interested in setting up Subversion for yourself, let me know and I might be convinced to lend you a hand.
