The Stack Overflow Podcast

Tarn and his brother Zach are the brains behind Dwarf Fortress and the community that rose around it.

Dr. Tarn Adams received a math PhD, but left his post-doc because he was too busy making games.

A bug created the statue Planepacked, a massive structure that contained the entire history of the world as well as 73 copies of the statue itself.

Many people, including one of our hosts, found out about Dwarf Fortress through a Let's Play session in a fortress called Boatmurdered.

If you want a more human readable version of Dwarf Fortress, you can wishlist it on Steam or use one of the Lazy Newb packs.
