This is the first iteration of a short game I’m making that tries to interactively explain some of my favorite math questions / ideas. My goal is mostly to get the player curious and not necessarily to explain absolutely everything. There were a lot of fun technical parts to building this: - For implementation reasons, it’s much easier if the lines all have integer intersection points with each other. To do this, when a new line is added I “cheat” by rounding intersections to integers and then splitting the old lines at the intersection into new linds (with potentially different slopes)…
Figure is a daily logic puzzle game2022 · figure.game · ▲417Hello, HN! Figure is a little side project I’ve been working on. Someone described it as Bejeweled meets Wordle. I built the puzzle interface and website in Next.js and React, which was a first for me and overall a great learning experience. The daily puzzle data is queued up in a PostgreSQL table. Another table stores anonymous solve stats. Once a day, a cron job hits a serverless API that promotes the next puzzle as “live” and prompts Next.js to update the prebaked static site with the new data. The game state is managed with Redux and your stats are persisted to localStorage. Framer…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
