One day Erlang training.


This training should get you started with Erlang and understand how to design a highly available distributed system. Because there is only one day, we focus on the essential concepts and skip over many details that would be covered in the normal three days course.

You need a schedule, man


Have three kinds of projects/work:

  • money making (gotta buy bread)

  • first class (generally involves a large number of users and/or me having a lot of fun)

  • second class (satellite and toy projects)
