It's okay to come even if you're not sure what to work on. We do ask that if you find yourself talking about code or other subjects more than showing / learning, then that's a sign to whip out some code and explore what you're talking about programmatically. Ask others if you need help doing this.
Good questions to ask during the hack night:
- What are you working on?
- What problem are you solving?
- How can I help?
- Want to pair program on some topic?
