The score comes from our model.

• Show HN: Popkern – open-source CAD kernel with G2 corner blends, browser IDE · score 7.5

  Popkern is an open-source BRep CAD kernel in Rust with a browser IDE, scriptable parts via Rhai, and MCP support for AI agents. It implements advanced CAGD features like G2 corner blends, exact booleans, and watertight tessellation, aiming to be a research-class yet accessible kernel.

• Show HN: Phobos – a tiny kernel language that now runs LLMs on a 2019 GPU · score 7.3

  Phobos is a tile-based GPU kernel language (Triton-inspired, MLIR/LLVM-based) that also powers a full GGUF LLM inference engine and an OpenAI-compatible server. It targets low-VRAM machines with expert caching for MoE models and reports decoding at or above llama.cpp speeds while reaching 87% of cuBLAS SGEMM throughput. The compiler-plus-runtime plus clustering story makes it an unusually ambitious single-author systems project.

• Show HN: Kcc, a C compiler built solo with an LLM on $100/mo boot Linux kernel · score 7.3

  kcc is a C17 compiler written entirely in ARM64 assembly as a literate program, with the source itself being a ~1000-page PDF book. It self-hosts, cross-compiles to x86-64, and can build real software like Lua, SQLite, DOOM, and even boot a Linux kernel. The project is technically impressive but niche due to its unusual language and documentation format.

• Show HN: An eBPF kernel guard for vTPM access · score 6.8

  tpmlsm is an eBPF-based kernel guard that restricts access to the TPM device to an allowlist of binaries, enforced via BPF LSM. It's interesting because it uses eBPF and IMA file hashing to create a root-resistant security layer for TPM access, with clear documentation of its approach and limitations.
