Learning about POTS is one of those areas I return to whenever I want to remind myself of the power of collective ingenuity with technology. The system is so well buttoned up, so reliable, and _so_ darned complicated… and it keeps humming along.
and standards – the power of standards. Another area that I stop and let myself get amazed at is the NTP – network time protocol. All the systems kept in sync within tolerances allowing for bidirectional information transfer (such as ‘real time gaming’) that appear to be instantaneous to the players… and much like POTS, it’s hard to believe just how much is involved to give the illusion of a “tin can + string” straightforward connection.
