I did some experimental archaeology in college as an Anthro major. I still have a bunch of chunks and flakes of obsidian and my flint knapping tools. The sharpness of obsidian is well established.

For the last few years I've worked on the same campus as Nalo Hopkinson. I have only read Sister Mine, so far, and loved it. I have been to one of her readings, and I also think she's very… » 7/23/14 1:43am 7/23/14 1:43am

I didn't know about this principle, but it is something I am always looking for when I query relational databases, and something I'm trying to prevent when I design databases for applications. Accurate reports require selecting data joined from multiple tables, and it's often possible to join sets of data on criteria… » 7/07/14 5:00pm 7/07/14 5:00pm
