I found something interesting in FreeBSD ports today:
/usr/ports/misc/tempcontrol/pkg-descr Tempcontrol is a temperature control program. In its current version it is specifically designed to control the temperature of beer fermenters in a fridge. It controls the temperatures when necessary by turning on either the fridge motor to cool the surroundings, or a light bulb to warm them. The specific brewing-related details are relatively minor, and future versions may become more general-purpose. Read the file README in the distribution for more information. At a later date there will be real documentation.
Wait . . . seriously? That has to be the coolest explanation for a piece of software I’ve ever seen. Now, I just have to wonder whether law enforcement officers would consider that program drug paraphernalia.
