DevOps Mastery Graph
An interactive prerequisite map for the Harbour.Space DevOps course. It highlights the foundations students often miss before Docker, Kubernetes, CI/CD, cloud, observability, and secrets management.
Short courses and reference material
Small, practical courses with a lesson-first structure: learn one workflow, practice it immediately, and keep a reference sheet for later.
Git
Git Worktrees for Parallel Coding
A five-lesson interactive course for creating isolated task checkouts, integrating finished work deliberately, maintaining worktree metadata, and running several bounded coding tasks without losing state.
Operations
Theory of Constraints for Service Businesses
A six-lesson interactive course on diagnosing service-flow constraints, exploiting and subordinating around scarce capacity, connecting flow to throughput economics, and running a falsifiable four-week improvement experiment.
Claude Code
Claude Code Agents View
An interactive course on using Agents View as a local work queue for background Claude Code sessions, inspecting Git worktrees before preserving isolated changes, and using agent teams for bounded parallel collaboration.
