Operating Systems for MAANG Interviews
A book-shaped table of contents for operating systems at MAANG interview depth: foundations through processes, threads, concurrency, CPU scheduling, memory management, file systems, I/O, security & isolation, Linux internals, cloud/Kubernetes/observability, advanced kernel topics, and interview preparation — cross-linking existing sre/linux-networking, kubernetes-security, and patterns/concurrency notes instead of duplicating them.
Site Reliability Engineering: From Foundations to Internet-Scale Systems
The complete 184-chapter, 15-part Site Reliability Engineering curriculum — from Linux internals and distributed-systems theory through reliability engineering, observability, incident response, platform engineering, and Staff/Principal-level MAANG interview preparation, ordered the way SRE expertise actually develops rather than as a topic index.

1 — Linux Internals Every SRE Must Know
The kernel-level mental model — syscalls, the VFS, the scheduler — that turns 'the server is slow' from a guess into a diagnosable claim.
10 — gRPC
Why internal service-to-service calls increasingly run on gRPC instead of REST, and the deadline propagation and streaming semantics that change how you debug a slow call chain.
11 — TLS and Certificates
The handshake, cipher negotiation, and certificate chain validation that fail silently until an expiry takes down a service nobody remembered depended on it.
12 — Load Balancers
L4 vs L7 load balancing, health check design, and why a load balancer's own failure mode is often the single biggest blast radius in the stack.
