ETA Guesser

I built a web game where you guess drive time between cities using live traffic. You get scored by accuracy (exponential decay—from ~1000 for a perfect guess), and there are solo and private match modes with leaderboards and detailed stats. Try it: https://etaguesser.com/ Tech: React + TypeScript, Supabase, Mapbox GL w/ live traffic. Happy to answer anything—game math, anti-cheat, or traffic quirks.

ETA Guesser launched on October 17, 2025 with 12 votes, #913 of 8,178 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.

  • I built a transit travel time map2023 · map.henryn.xyz · ▲255

    This was something I built while trying to look for housing in Toronto that was decently transit-accessible to my office while still cheap. The backend is written in Rust. It parses public GTFS data from transit agencies and performs a simple heuristics-based BFS on the bus lines to calculate how long to reach all points in a city. The frontend uses React and Mapbox GL to render each individual road segment based on how long it takes to reach. This project was a great excuse to learn Rust, deployments, and mapping. The source code is here if you are interested:…

    Hi HN, I made a web game to practice country locations a while ago and HN liked it, so I thought I'd post my updated version as well. As for how the game works and feels, I'd really recommend you checking it out for yourself, it's free, no signup, no ads. The tech stack is Vue + ts + Tailwind/Daisy for the looks. The learning algorithm is a slight modification of the ts version of FSRS. If you have anything to add, it's open source as well (https://github.com/koljapluemer/learn-worldmap), although not well documented yet. In the end it's just a little sideproject,…

  • I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

  • Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
