The art of deleting code
summary
Describes a repeatable process that actually removed 50,000 lines of Ruby code at work, using concrete tools: git blame, git log --follow, git bisect to find when and why lines stopped being used, plus static analysis and running code coverage in development to spot dead paths. Emphasizes small, focused commits, stash workflow, and commit messages that cite the exact introducing and removing SHAs so reviewers can verify the deletion.
