Today I Learned: 1) The Beatles were so ahead of their time that they quit performing live because their equipment couldn't handle the crowds. There didn't exist commercial speakers that could play reasonably well over the roar of the kinds of crowds the Beatles routinely generated. At some point, they decided that there was no point in playing live, because nobody could hear their music anyway. That was when they started devoting themselves full-time to studio recording. 2) ...proper application of a chop (the Asian style seal/signature). If you press it with a hard backing behind the paper, it doesn't apply very well (imperfections in the chop surface show up really strongly). A soft backing works much better, like a folded paper towel. 3) Very important cable management trick for serious cabling situations -- label both ends of the cable with a unique number, with a nice tape that won't come off or gunk up. That way you shouldn't ever have to go manually tracing a wire through a thick bundle of cables.
