Discover how to design a compact, paper-based debugging system you can use on trains, planes, and couches to reason about bugs systematically—without your usual IDE, multi-monitor setup, or internet connection.
How a physical deck of debugging prompt cards can turn chaotic bug hunts into structured, collaborative, and surprisingly calm problem-solving rituals.
How hand‑drawn maps, deep architecture diagrams, and lightweight documentation can turn chaotic legacy systems into navigable territory for developers.
How “paper-first” regression routines, natural language oracles, and structured checklists can help teams catch subtle regressions before CI ever runs—and make automated tests more effective.
Explore how an analog, reusable tabletop gameboard can turn software debugging into a tangible, engaging practice system—independent of programming language and endlessly extensible.
Refactoring legacy code doesn’t have to feel like open-heart surgery. Treat it like assembling a physical puzzle on your desk: make technical debt visible, use visual maps, and apply behavior-preserving changes selectively, where they matter most.
How to turn scattered logs, metrics, traces, and tickets into a single, tangible ‘control tower’ that helps you understand and tame long-lived, hard-to-reproduce software bugs.
How to use tabletop-style war games, security thinking, and legacy code techniques like characterization tests and golden masters to safely refactor fragile systems without blowing them up.
How to transform incident postmortems into a physical “puzzle wall” that makes outages easier to visualize, share, and learn from—while reducing hero culture and improving reliability.
How a low-tech “paper circuit” lab with index cards and string can make concurrency, race conditions, and real-world mitigation strategies intuitive and concrete.
