302 Exercises: The Whiteboard and the Shared Tree

Setup

• Attendees work in pairs or trios, each person acting as one node with a terminal of their own. Working alone, run both nodes from two terminals.
• Git, and a scratch directory you can delete afterwards. Every exercise runs in a throwaway repository, never in a real project.
• Intent 3.2.3 or later, for Exercises 1 to 3 and the first two stretch goals.
• A shell. The examples use zsh, the shell the course's evidence comes from.

Exercise 1: Register Two Nodes (15 minutes)
