Technical Debt

Using a home renovation analogy of discovering a labyrinth of old pipes behind a wall, this piece explains technical debt as the accumulated cost of past shortcuts. It distinguishes between intentional debt (a conscious tradeoff) and a mess (careless neglect), drawing on Uncle Bob's Clean Code philosophy. The key insight is that debt is painless until you try to change something, at which point it compounds. The recommended mitigation is writing tests to create a safety net that makes future changes less risky.
