bliki: Strangler Fig
During a vacation in the rain forests of Queensland in 2001, we saw some strangler figs. These are vines that germinate in a nook of a tree.

Let's clarify with an example. Let's imagine we need t
On Pair Programming
Teams are often reluctant to switch pairs, but what if we rotate pairs every day? We did an experiment with three teams and learned that pair swapping frequently greatly enhances the benefits of pairing. Here we share our experiment design so that others can experiment with rotation frequency. Rotating pairs means that after working together for some time, one half of the pair leaves the story, wh
