… some dumbshit “Agile” software development technique where you share a dirty keyboard to type some code and review each line. The programmers usually switch roles unless one starts picking their nose or bites their fingernails which usually ends up with one doing all the typing.
There is usually and imbalance and plenty of disagreements as one programmer is vastly inferior to the other.
Add another person to the group and it becomes that really dumb idea called Mob Programming who Woody Zuill is a passionate advocate of.
