Comment Re:Git could use revision numbers (Score 1) 442
To those who are unfamiliar, each commit in Git has a SHA1 hash which is used as an identifier instead of a revision numbers. Unfortunately, they are very unwieldy to communicate to others. At work we always use the name and date-time instead, but that has problems as it doesn't convey the branch for instances when it matters.
You don't have to use the entire SHA - e.g. for a long unwieldy SHA like a809deeb979c33a7cc9ac48da72a2a22eaa7dc62, you can simply refer to it as, say, commit a809deeb, or even a809 - as short as you like, as long as it's still unique. In most repositories, the first 8 characters should be a pretty safe bet.
