visualize pair activity with two keyboards and two mouses
Pair programming is believed to increase code quality. But the biggest and most common pitfall according to the Agile Alliance is that both programmers don't equally engage with a task throughout the pairing session. Even though we know this, it is easy to lose track of time and for example forget to switch roles in order to keep a balance during pairing.
This little utility can help you. It associates system wide mouse and keyboard activity to both programmers and shows a big green field when both are equally active and an increasingly reddish field as one is over or under engaging. The utility requires a dedicated mouse and keyboard for each pairing participant. It is very easily confirgured and provides a nice visualization of your pairing session.
