A custom virtual machine for the Stars! 4X game nullprogram.com
Stars!VM is a 32‑bit Windows executable that embeds a custom 80286 emulator and a Win16‑to‑Win32 bridge to run the 1995 4X game Stars! without any external emulators. The author adds differential fuzzing, hot‑routine patching, I/O buffering and asset compression, achieving about a 2× speedup in turn generation.

What Go Taught Us About Java Garbage Collection codenameone.com
ParparVM’s GC was tuned by lowering the allocation‑trigger floor, adding configurable thresholds, parallel marking, mutator assistance, and proper weak/soft reference handling. These changes cut RSS from 98 MB to 38 MB, reduced worst‑case GC pauses from seconds to sub‑second, and improved cache hit rates with a recency‑based eviction policy.
