Notes from the trenches.
Deep dives into AI infrastructure, distributed systems and platform engineering — each written around a dataset or a system you can rerun, break, or build yourself. No hot takes without a methodology section.
AI Infrastructure

interactive handbooksRaft, step by step
A self-paced, interactive walkthrough of the Raft consensus algorithm — the protocol that keeps etcd, Consul, TiKV and CockroachDB coherent across failures. Every concept comes with a live cluster you can break.
Paxos, without the Greek
Demystifying the original consensus protocol — from single-decree to multi-Paxos, with interactive state machines showing exactly where messages go and why they matter.
Consistent hashing, visualized
How modern systems distribute data across nodes — from the basic ring to virtual nodes, bounded loads and jump consistent hashing. An interactive ring you can add and remove nodes from.
About
Written by Duc Dinh — DevOps & Site Reliability Engineer in Ho Chi Minh City. 10+ years building infrastructure that doesn't page you at 3AM. These notes are how I learn: by collecting data, building the smallest thing that proves the point, and writing down what broke.
