pnn64/README.md

DevOps engineer based in Paris. I write mostly Rust, with an interest in systems programming, graphics, and performance.

Projects

  • DeadSync - A rhythm-game engine for StepMania/ITG charts, focused on timing, performance, and compatibility.
  • rssp - A Rust library and command-line tool for parsing and analyzing StepMania simfiles.
  • itgmania-harness - Testing tools that run ITGmania's own code to generate reference results for compatibility checks.

Upstream contributions

I also contribute performance improvements to existing open-source projects. Some merged examples:

Project Contribution
wgpu Reduced temporary allocations during bind group creation
glam Simplified quaternion identity checks
rand Optimized weight lookup and iteration
Rerun Removed allocations when resolving archetype field names
image Removed temporary allocations during APNG frame disposal
png Removed temporary buffers when writing APNG frame data
zstd-rs Reduced buffer growth and initialization overhead during decoding
rtrb Optimized folding over ring-buffer read chunks
twox-hash Avoided unnecessary secret copies in seeded XXH3 hashing

Within the rhythm-game community, I've also contributed audio sample-rate configuration and rendering fixes to ITGmania, along with improvements to the Simply Love theme.
