    Hello World Java Polyglot▲15

    I wanted to see how much simpler native code integration has become with GraalVM's polyglot, when compared to JNI. It's less than 100 lines all up (including the POM). (I feel kinda stupid posting a "hello world" to HN, but this is a hell of an improvement.) Linux only at the moment.

    I built a Macrodata Refinement game inspired by Severance▲5

    Fully leaned into vibe coding this time around. Started on v0, at some point ejected into running locally (getting v0's exported folder to run locally was a challenge), then iterated with Cursor over the course of a few hours. Really neat how much can be accomplished just conversationally these days.
