- Walking outside is beneficial for mental clarity and problem-solving.
- Vicki Boykis advocates for 'walking around the app' to ensure cohesive design and smooth functionality.
- For data-transforming software like compilers, exploring non-trivial outputs can reveal optimization opportunities.
- Example: Identifying and fixing a redundant float_abs operation in PyPy IR.
- Tools like Compiler Explorer lower barriers to checking compiler behaviors and assumptions.
- Regularly reviewing IR can uncover hidden bugs or inefficiencies.
- Investing in developer-friendly tools improves usability and fosters better understanding among users and colleagues.
