How QBE compiles SSA IR to machine code, with a close look at its linear-scan register allocator and the inline caching techniques production JITs use to recover lost megamorphic performance.
Build a production-shaped eBPF/XDP packet classifier from scratch in C. Real code, real architecture, and a clear roadmap to extend it into a senior-level systems project.
Build a runnable LSM-tree key-value store with a write-ahead log in Rust, from WAL append to SSTable flush to compaction. The exact project to make your CV read like a database engineer’s.
Demystify how LLM inference works by building a tiny inference engine from scratch. Covers tokenization, the transformer forward pass, KV cache, and decoding.
A step‑by‑step guide that shows engineers how to gather and interpret utilization, saturation, and error metrics, then translate them into actionable architecture changes.
