Video Description
That branch you created three months ago? The one you've been dreading to merge? Let's talk about why that dread is justified. Here's the thing people forget: while you're off working peacefully in your nicely isolated branch, life goes on in main. And that's where the pain comes from.
What you'll learn: • Why merge pain is exponential, not linear • The multiplication math: it's X × Y, not X + Y • What counts as "long-lived" (hours, days, sprints, months) • Three types of conflicts (and why textual conflicts are the easy ones) • The fear spiral that makes everything worse • Refresh merges: pulling main into your branch • Warning signs your branch is too old • Why better merge tools aren't the answer
Key insights: • Merge pain is proportional to isolation time • Your teammates didn't stop working just because you branched • You're not merging code — you're merging history • Semantic conflicts: code merges cleanly but doesn't compile • Behavioral conflicts: code compiles but doesn't work • The fear spiral is self-reinforcing — the only way out is to break it early • A ten-minute merge every day beats a three-day merge once a month • Prevention beats cure
This applies whether you're using GitHub, Azure DevOps, GitLab, or any Git-based workflow.
