- DevOps / infrastructure / observability family ROUTER. Split into focused sub-hubs - route to: devops-linux-internals (kernel, boot, memory/NUMA, storage/filesystems, virtualization, io_uring, cgroups/namespaces, sandboxing, immutable Linux, privilege); devops-linux-admin (sysadmin, systemd, package management, shell scripting, host networking diagnostics); devops-containers-cicd (Docker, Kubernetes, CI/CD pipelines, Terraform/Kafka IaC, git workflows, library packaging); devops-observability (Node/OTel observability, Pino logging, Sentry, eBPF, Linux perf tracing). Pick the sub-hub matching the task. [source]
- This hub routes to on-demand reference files under references/. See each spoke for depth. [source]
