  • Nixpkgs Committer. Commit nomination/grant discussion

    I’ve worked with @LunNova on finally enabling PIE by default, CMake 4 fixes, and LLVM packaging changes relating to ROCm. I’ve found her to be highly skilled, easy to collaborate with, good at diving into unfamiliar issues across diverse areas quickly, and to have good taste for maintainable solutions. I strongly endorse her for commit access. ~ emilazy, nixpkgs core team member I nominate @LunNova for commit access. Luna is currently the most active maintainer on the ROCm (compute on AMD GPUs) package set which, since earlier this month, gets redistributed via cache.nixos.org! I have found her to be very capable when dealing with the enormous size of these packages and in her communication with upstream. Other notable contributions are the PIE enablement on packages built with GCC and the Go compiler. Luna has 94 merged PRs and close to 300 reviewed PRs. She started contributing in 2022, but really ramped up her contributions in 2025. I am confident that nixpkgs will benefit from granting LunNova commit privileges. I enjoy interacting with her! ~ mweinelt, nixos infra

Security hardening: PIE by default§

Led the initiative to enable Position Independent Executables by default for GCC in nixpkgs, improving ASLR coverage across the distribution. Attempted and reverted similar effort for Go due to time constraints near release window and subsequent lack of time.

  • #449995 — go: restrict default pie patch to known good GOARCH
  • #452791 — gcc: disable enableDefaultPie when !hasSharedLibraries
  • #458867 — go: only apply PIE by default when CGO is enabled
  • #461615 — go: revert default PIE changes

LLVM & compiler infrastructure§

Minecraft modding§

Core developer of the Feed the Beast Launcher (2012-2013), the dominant Minecraft modpack platform of its era. FTB's platform was later folded into CurseForge, which was acquired by Twitch/Amazon (2016) and then Overwolf (2020). ~20 merged PRs including the auto self-updating system, logging framework rewrite, window management, and performance improvements. Managed via custom IRC chatops system, source lost to the sands of time.

Own projects:

  • github:MinimallyCorrect/TickThreading — Multi-threaded Minecraft server mod. Used bytecode transformation at load time to parallelise world ticking across dimensions and within dimensions. ~2500 commits, ~3K LoC Java. Performance over correctness — what could go wrong? Way too much.
  • github:MinimallyCorrect/TickProfiler — Minecraft server profiler for finding which entities and tile entities are causing lag. ~200 commits, ~2.5K LoC Java.
