A from-scratch, runnable Python project that mimics the memory management at the heart of modern LLMs: sliding-window attention with dynamic eviction and a prefix-cache KV store. Includes architecture, code, tests, and a roadmap to senior-level.
Throughput and latency measure different things, and most of the systems pain we feel at scale comes from pretending they don’t. Here is how they actually trade off, with real production patterns.
A practical, runnable build guide for an HTTP load balancer with health checks and least-connections routing. Architecture, code, and a roadmap to senior-level extensions.
Copy‑on‑write lets multiple threads share the same memory until a write occurs, dramatically cutting duplication and boosting throughput in concurrent systems.
