I've open sourced DD Poker
I'm the original author of DD Poker, a Java-based computer game that ran on Mac, Linux and Windows and originally sold in stores in physical boxes. I shut down the backend servers in 2017 but the game is still functional and people can still play each other online even though the central lobby and find-a-game functionality no longer work. I've been asked over the years to release the source code, especially during the pandemic, and again this year. I finally got motivated to clean up the code and put it out there.

In plain words
DD Poker is an open-source Java-based poker game originally released as a commercial product for Mac, Linux, and Windows. The original author has released the 20-year-old source code after shutting down the backend servers in 2017. While the central lobby and matchmaking features no longer function, players can still play against each other online. The codebase uses older dependencies like Spring and Wicket but remains compatible with Java 1.8.

Hey there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma. Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can…
