• Kilobyte

  There's been a lot of confusion over 1024 vs 1000, kbyte vs kbit, and the capitalization for each.

• Dating Pools

  [[Woman is sitting on the ground with her elbows on her knees and her hands on her chin. She is talking to a man.]] Woman: This sucks. The median first marriage age is 26. The pools of singles is shrinking. I'm running our of time. Man: Actually, not quite. Man: Yes, older singles are rarer. But as you get older, the dateable age range gets wider. An 18-year-old's range is 16-22, whereas a 30-year-old's might be more like 22-46. [[Man points to a chart]] Text on chart: Standard creepiness rule: Don't date under (Age/2 + 7) Man: I did some analysis of this with the Census Bureau numbers just last weekend. Your dating pool actually GROWS until middle age. So don't fret so much! [[Man is pointing to new set of charts. The first chart is labeled Singles, and is a decreasing graph. The second graph is labeled Dating Pool, and is a bell curve.]] Woman: Did you analysis say anything about the dating prospects of people who spend weekends at home making graphs? Man: Come on. Somewhere at the edge of the bell curve is the girl for me. {{title text: The full analysis is of course much more complicated, but I can't stay to talk about it because I have a date.}}
