Episode notes
Debugging in Reality vs. Tutorials
- Most programming tutorials showcase perfect code, not realistic debugging.
- Real-world coding involves significant debugging time, a skill often learned inductively.
Two Modes of Programming
- Programming has two modes: building and investigating.
- Switch to investigative mode when assumptions about code behavior are wrong.
Knowing When to Switch Modes
- Use the "standard strategy" (trying most likely fixes first) in build mode.
- Repeatedly trying the same failing fix signals a need to switch to investigative mode.
