It's little things that both amuse and amaze me about today's technology.
It tickled me when Scrutiny started up and started working exactly in sync with the sixth pip of the time signal on the radio. (It's set to scan one of my sites at midday on a Tuesday)
Maybe younger people take this kind of thing for granted but it's taken some amazing technologies to make that happen so accurately - my processor can perform several thousand million operations a second, my system is regularly updating its time from a time server. Rather ironically I wouldn't have noticed this effect if I'd been listening to R4 on DAB rather than FM!
