Have fun! Remember that you’re at the Hackathon to have fun. Yes, it’s a competition but it’s also a place to experiment, meet interesting people, learn something new and build something from scratch. Don’t stress yourself out too much if you don’t accomplish what you set out to do, or if you don’t win.t $99, it’s not cheap but it’s the best. If you do Hackathons regularly, or you need to make a video of a new app that you’ve built and post to Hacker News, this software is worth it. If you don’t want to spend $99 for Screenflow, you can use the built-in Quicktime player to make a screen recording.
