GitHub Flow – Scott Chacon So, what is GitHub Flow? Anything in the master branch is deployable To work on something new, create a descriptively named branch off of master (ie: new-oauth2-scopes ) Commit to that branch locally and regularly push your work to the same named branch on the server When you need feedback or help, or you think the branch is ready for merging, open a pull request After someone else has reviewed and signed off on the feature, you can merge it into master Once it is merged and pushed to ‘master’, you can and should deploy immediately For teams that have to do formal releases on a longer term interval (a few weeks to a few months between releases), and be able to do hot-fixes and maintenance branches and other things that arise from shipping so infrequently, git-flow makes sense and I would highly advocate it’s use. ...

Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%. Donald Knuth (via When optimal matters ) ...

When optimal matters | Playing with Objects The rules of optimization (…) When you are thinking on making an optimization: First time: Don’t do it! Second time: Don’t do it yet! Third time: Ok, but you first profile and measure, and then optimize
