The Haskell Hackathon is underway, live in Freiburg. In a lovely space, kindly provided by Freiburg University. This is the second hackathon this year, after the January one in Oxford. The attendee numbers have doubled, with nearly 30 hackers.

This hackathon is also the first to receive commercial sponsorship, with Credit Suisse and Galois, Inc kindly providing tshirts. It’s great to have commercial interest and support of the Haskell community!

Tshirt kindly modelled by Phillip Heidegger.

Underway, power is fed from the ceiling :)
