A Discussion of Basic vs. Applied Research in the Software Domain and the Creation of Erlang
Bjarne Däcker recounts the story of CSLab at Ericsson, the birthplace or Erlang, how it started, some of the projects leading to Erlang, and its eventual success inside Ericsson as Erlang/OTP.

The Joy of Testing
John Hughes shows how to explore the bugs of a code by creating a series of tests in Erlang and using multiple test frameworks, discovering the faults and evaluating the frameworks while doing it.

Death by Accidental Complexity
Ulf Wiger shows how concurrency can lead to accidental complexity if it is badly implemented in code, becoming a project’s point of failure. Wiger also advises on how concurrency should be addressed.
