The hackathon will be on Day 2 of the event (Nov 5), approximately 11am-5pm.
 
  
The hackathon is self-organized into small groups. We’ll also have ideas and help available for newcomers. Any topics related to ZFS are fair game. It’s intended to be cooperative, but we do usually have a few small prizes that are awarded by popular vote of the participants.

Hackathon presentation [https://www.youtube.com/watch?v=rfzffM5kbe8 video]
  
You may want to bring a laptop with access to a development environment (e.g. an Ubuntu virtual machine). We’ll have folks who can help you set that up too if needed.  There are often also hackathon projects whose end result is a design document, proposal for a process change, or documentation. These wouldn’t necessarily require a development environment or even a laptop.
