Ask HN: Tomorrow is my first hackathon, any advice?

To make the most of your first hackathon, focus on having a clear idea or problem statement before you start. Don't worry too much about the technology or tools you'll use; instead, think about what you want to achieve. Form a diverse team with different skill sets to bring different perspectives to the table. Prioritize building a minimum viable product (MVP) over creating a perfect solution, as the goal is to demonstrate your idea within a limited timeframe.
