We often look to Silicon Valley for metaphors to explain technology. But sometimes, the most perfect analogies have existed in our own heritage for thousands of years.
I recently learned about the difference between a Git Author and a Git Committer.
This sounded familiar. It is exactly the story of how the Mahabharata was written.
When Maharishi Ved Vyas (The Author) was ready to compose the epic Mahabharata, he needed someone to write it down. He approached Lord Ganesh (The Committer).
But this was not a simple dictation. It was a rigorous Code Review.
The Condition (Branch Rules):
Lord Ganesh set a rule: "I will only write if you dictate without pausing. If you stop, I stop." (Continuous Integration!)
The Counter-Condition (Quality Check):
Vyas replied: "Agreed. But you must only write a verse after you have fully understood its meaning."
Vyas would compose a complex verse (The Code). Ganesh would pause for a split second to decode the logic (Review), verify the truth (Test), and then inscribe it (Commit).
In the world of Open Source (Linux, etc.), you are often Vyas. You write the patch.
The Project Maintainer (like Linus Torvalds) is Ganesh. They review your work, apply their stamp of approval, and commit it to the repo.
The Author Date is when you had the idea.
The Committer Date is when the idea became history.
