"It often works", he said. Jack shook his head > ... Once upon a time there was Garry that had been the designer of the Hi-Fi that worn his name. He was providing his users with a remote for the Hi-Fi. Then an enterprising distributor showed up in town and started bundling Garry Hi-Fi together with a remote, that had a special function: it allowed to record the music to a pendrive provided that the hour was even. Each new user at the beginning was little puzzled with the feature: 1. It provided an amount of uncertainty =E2=80=93 some customers when holdi= ng the remote in their hands had small but causing discomfort part of their minds focused on the question: "Is the hour odd or even?" 2. It caused disappointments when user wanted to record the music currently being played, but the hour was odd. 3. The user's were questioning the meaningfulness of such feature (side note: this recalls me the reactions to Intel's hyperthreading, the "not full hardware threads") However, over the time, point (1) basically dropped. The anxiety simply dispersed. The point (2) resolved with "it's not that big of a deal, with calm attitude all I need to do is simply wait approx 1 hour to record". (3) resolved with "the feature is a must-have, it allows me to effectively move my music to the computer or mp3 player". Who would today want to resign from hyperthreads? -- Sebastian Gniazdowski News: https://twitter.com/ZdharmaI IRC: https://kiwiirc.com/client/chat.freenode.net:+6697/#zplugin Blog: http://zdharma.org
