Reading code
summary
Claim: developers spend about 58% of their time reading code. Practical setup: print a one‑ to two‑page sample, run structured drills like First Glance and picking the five most important lines, then annotate and converge on meaning over repeated sessions. Tools and moves that actually help: run and debug the project, generate or draw dependency/state diagrams, use git annotate to read history, refactor privately for clarity, and ask IDE/AI features to explain code when semantics or regexes block comprehension.
