Warm and crisp on the edges. A bagel with a bit of bite.
Summary
The article discusses the practical application of binary search algorithms in real-world software development, specifically using git bisect to find bug-introducing commits in a monorepo. The author argues that while interview systems requiring algorithmic knowledge are flawed, learning binary search is essential, as demonstrated by git's bisect feature which implements binary search to efficiently locate problematic commits among hundreds or thousands of daily commits.
