Hi!

We had a wonderful week here in Cochabamba, Bolivia. Juan-Pablo, Juraj and I have taught Pharo and Moose during 5 days. Was pretty cool!

Here is a script that shows that one of the group was able to produce in just 3 days.

The figures analyze the content of my package-cache directory. It shows the number of commit per day, per hour, per author.
