A tested Rust-and-C FFI boundary covering ABI layout, pointer validation, ownership, panics, error reporting, callbacks, versioning, and cross-language harnesses.

A pattern may begin in one input chunk and finish in the next. I explain the state, offsets, and split-point tests needed to keep a Rust streaming scanner correct.

Most WebSocket tutorials start at the API. This one starts at the wire — electrons, NIC interrupts, kernel socket buffers, the TCP state machine, the HTTP upgrade handshake, the binary frame format — and works up to what ws.send() actually does.

Most comparisons of gRPC streaming vs unary stop at the API surface. This one goes to the wire — HTTP/2 frames, protobuf framing, peak memory, and latency to first byte.

How I built a custom code execution engine backed by a Rust/Axum microservice, embedded directly in blog articles. Covers the security model, subprocess isolation with setrlimit, HMAC request signing, and the tradeoffs behind every decision.
