practice makes permanent

so, i went looking for the math to make a slat absorber (a.k.a. a slot absorber – depending on whether you’re a glass-half-full or a glass-half-empty kind of person…) this week. turns out that, if you search for the equations to build one, you’ll probably get the wrong answer. this is most likely due to a typo in a book that got copied in the next edition of the same book, and then, through the power of the internet and a procedure used in elite circles called “copy-and-paste”, was widely distributed. my dad always said that practice doesn’t make perfect – it makes permanent. practice a mistake, and you’ll be stuck with it.

anyways, the correct equation for a slat absorber and the discussion regarding the identification of the discrepancy can be found here and, in more depth, here.

wakey wakey!

well well well… i’m back. funny that i spent so much time on stalkbook instead of filling up my own blog with content. time to come home. so, i “deactivated” my stalkbook account and came here. no real reason why, thanks for asking… just got tired of sending data to the man…

on with the show!

Danish prices… Part 1..

So, just to air some laundry that we talk about often, I’m going to put some price comparisons showing the difference between what we’re expected to pay for things at the local stores here in Denmark, and what other people are expected to pay for them elsewhere…
