Space Trader (Ported from Palm OS to Vanilla JavaScript and HTML)

Hi HN! I brought my favorite game from Palm OS to the web as a hobby project. In Space Trader, you can trade goods, hunt bounties, amass a fortune, buy a moon and retire. One of the parts of this project I enjoyed the most: To aid debugging and unit testing, I use a deterministic random number generator called GameRand. In debug mode, I can capture the random seed and log of every action taken in the game. Then I can replay that to reproduce a bug or create a test. I ended up creating nearly exhaustive test coverage this way. A write-up with more technical details and links to source code:…

    A self-running space economy SIM in Rust and BevyJul 2026 · github.com · ▲110

    I built this with Claude cause I always wanted to tinker with a simulation economoy and I love space themes. A space-economy sim where nothing is scripted. A few hundred autonomous ships each run their own planner. Some chase the best trade route, take a delivery contract, refuel, retrofit at a shipyard, or dock so the crew can rest before morale tanks. Markets price everything off supply with shortage-urgency multipliers, factions tax and subsidize, populations migrate when they're unhappy, and stations that go broke get abandoned and rot. It started as an Elixir/Phoenix prototype, but…

    I was tired of games like Mafia Wars and wanted a phone-based MMO Strategy game where hundreds of players could actually engage each other on a 2D map, so I made one. I track the state of the game each night so we can display a visual timeline of territory controlled by each alliance. (example: http://bit.ly/q5CFhU) I use jQuery mobile for the front end so it runs on most phones (via Phonegap) as well as modern web browsers. The server side is handled by Java Servlets and MySQL. This started as a hobby - I'm not a developer by training - so I am very interested in feedback, suggestions, and…

    I left my FAANG job at 50 to build a sci-fi gameNov 2025 · ▲9

    I am a 50-year-old who left a FAANG Engineering Manager job to build a sci-fi game. I just released Outsider, a sci-fi narrative game with multiple endings. If you want to support my work, the game is now 15% off (https://store.steampowered.com/app/3040110/). I've always wanted to create a game. I moved from Brazil to the US to work at Big Tech, but after a career of customer focus, mission alignment and 360-degree feedback, I wanted to experience solo game development. While FAANG can be soul-crushing at times, I had a great manager and an amazing team. The pay and…
