Hi, I'm KitaSan (@cool-japan).

I'm building the COOLJAPAN ecosystem: a Rust-first, production-minded stack for
scientific computing + data + ML + trustworthy reasoning—designed to be
memory-safe, highly portable, and pure-Rust by default (minimal C/Fortran/FFI reliance).

What this ecosystem covers

  • Scientific computing & ML foundations (SciRS2, NumRS2, OptiRS)
  • DataFrame / data tooling (PandRS)
  • Semantic Web / graph reasoning / Digital Twin / Industry 4.0/5.0 (OxiRS)
  • Linear algebra & FFT primitives (OxiBLAS, OxiFFT)
  • Transformers-class NLP stack (TrustformeRS)
  • Pure Rust PyTorch (ToRSh)
  • SMT / formal methods toward "trustworthy AI" (OxiZ, OxiLean, TensorLogic)
  • Generative Jurisprudence (Legalis-RS)
  • Speech / audio AI tooling (VoiRS)
  • Mail Server / Client (RusMES)
  • GIS / Geospatial (OxiGDAL)
  • Audio / Visual / Movie (OxiMedia)
    …and more.

Why sponsorship matters

This is a large, interconnected system: performance work, test coverage, docs,
release engineering, CI, and long-term maintenance take sustained effort.

Your sponsorship helps me:

  • ship faster releases and keep APIs stable,
  • expand test coverage and compatibility,
  • improve documentation & examples,
  • fund CI, benchmarks, and performance tuning,
  • invest in security hardening and long-term maintainability.

If you rely on Rust for science/ML/HPC, want a safer alternative to legacy stacks,
or simply want Rust to have a first-class AI ecosystem—thank you for supporting.
