A practical guide to low-level systems engineering, focusing on POSIX and Linux. This book provides a collection of techniques and insights I've found invaluable throughout my career—many not widely known, but useful to anyone working with systems at a low level. The chapters climb outward: local filesystems on a single Linux host, filesystems across the network, datacenter networks, and the design of systems that survive failure—plus a chapter of standalone topics.
