Pull design decisions and best practices from engineering videos
Summarize OSS-maintainer talks, system-design deep-dives, and conference sessions — the reasoning behind the code, not just the code itself.
At engineering conferences, the actual value isn't the API surface — it's why a decision was made and which alternatives were rejected. SumTube structures each talk around its design rationale, migration cost, and architecture tradeoffs. "What did they say in that talk?" becomes a question you can answer from the summary alone, without rewatching.
