THINK ONE AND A ZERO<\/p>\n

Is our new glue gun powered on or off?\n<\/p>\n

We were recently in a hotel in Berlin Germany and the room heater had the line-circle (| O) symbol on it and we couldn’t remember whether line means on and circle means off, or the line means off and circle means on.<\/p>\n

Quality German engineering made the heater silent so there was no way to tell by listening. <\/p>\n

The next day we got home to find our new glue gun had arrived. Same problem. And glue guns take a few minutes to heat up so that’s annoying (and possibly dangerous)<\/p>\n

Wikipedia to the rescue<\/a>. <\/p>\n

Turns out it’s best not to think of it as a line and circle.<\/p>\n

Think of it as a 1 and 0.<\/strong><\/p>\n

Recall your computer science, logic, electrical engineering, whatever classes:<\/p>\n

0 is FALSE, low voltage, or off
\n1 is TRUE, high voltage, or on<\/p>\n

Boom. Retained for life. <\/p>\n
