Asking for a friend: With the use of Fourier series, I'm trying to solve an ODE of the form L*y'' + R*y' + y/C = r(x), where r(x) = 1 - x^2 for |x| <= 1, i.e. has a period of 2. To do so I need to represent 1 - x^2 as a Fourier series. In doing so I have to integrate e^(-n * i * pi * x), but I've reached a stumbling block. [more inside]

Apropos of nothing, why would the wiring going to the fog lights on a US 2002 VW New Beetle have an extra unattached plug on it? This is not the lowest model, but came with the fog lights standard. I wonder if one of the upscale versions had fog lamps with two bulbs in each light or something that would have required another plug. On second look, it occurs only on the drivers side wiring, the passenger side looks normal. Please stop me from agonizing over this superfluous detail!

Deeply conflicted, the circumcision we'd reluctantly decided upon was rescheduled until his seventh day. My husband and I got within a block of the doctor's office, our perfectly-formed week-old baby in his carseat, and simultaneously decided he was just right and we were just wrong. We turned around and never looked back, until . . . [more inside]

I'm a huge fab of Conundrum, a white blend wine lately out of Caymus Vinyards. However, here in Boston the suggested retail price of 24$ for a bottle of the '02 is more commonly 30+$. Also, local liquor stores rarely stay in stock. As someone who enjoys a bottle of wine with dinner and saving a few bucks, is there any other similar white (blend or otherwise) you can recommend for 10$-15$ or less? Or if you can find a cheap source of Conundrum outside of NH State Liquor Stores, please let me know! [more inside]
