restful_authentication howto, step-by-step (part 1)

Saturday, May 17th, 2008

There are more than a hundred thousand different ways of implementing authentication in ruby on rails. Authentication in the rails world is definetly not for the faint hearted. After some random reading through the rails wiki it seemed quite clear that there is one winner: acts_as_authenticated.

the Buddhist monk puzzle

Thursday, May 15th, 2008

A new puzzle, this time from Conceptual Blockbusting: A Guide to Better Ideas by Jams L. Adams:

One morning, exactly at sunrise, a Buddhist monk began to climb a tall mountain. A narrow path, no more than a foot or two wide, spiraled around the mountain to a glittering temple at the summit. The monk ascended at varying rates of speed, stopping many times along the way to rest and eat dried fruit he carried with him. He reached the temple shortly before sunset. After several days of fasting and meditation he began his journey back along the same path, starting at sunrise and again walking at variable speeds with many pauses along the way. His average speed descending was, of course, greater than his average climbing speed. Prove that there is a spot along the path that the monk will occupy on both trips at precisely the same time of day.
