Whence the name Ruffus?

Cylindrophis ruffus is the name of the red-tailed pipe snake (bad python-y pun) which can be found in Hong Kong where the author comes from. Be careful not to step on one when running down country park lanes at full speed in Hong Kong: this snake is a rare breed!

Ruffus is a shy creature, and pretends to be a cobra by putting up its red tail and ducking its head in its coils when startled. It does most of its work at night and sleeps during the day: typical of many python programmers!
