• 0031Git submodules without surprise detached HEADsGitSubmodules embed one repo inside another by pinning a commit, not a branch. Knowing that single fact prevents most of the pain — detached HEADs, missed pushes, and silent divergence after a pull.
• 0030Branching strategies: Git Flow, GitHub Flow, trunk-basedGitHow the three dominant branching models differ in branch count, integration cadence, and release rhythm — and how to pick one based on your release model, not the model's brand.
• 0029Stacked diffs: commits as review unitsGitTreat each commit (or tiny branch) as the unit of review, not a large feature branch. Smaller reviews, less waiting, better commit hygiene — and a non-trivial rebase tax to pay.
• 0028Ignoring files beyond .gitignoreGitLocal-only ignores, untracking already-tracked files, hiding local edits to tracked files, and a global ignore for OS junk — the four problems .gitignore alone doesn't solve.
• 0027Finding the commit that broke it with git bisectGitBinary search across commit history to find the first bad commit. Works manually or fully automated with a script — turning a needle-in-a-haystack search into log2(n) steps.
• 0026Three ways to squash, and when each is rightGitInteractive rebase, soft reset, and merge --squash all collapse commits into fewer commits. They differ in granularity, on which branch they leave the result, and how much history they preserve.
