Commit message guidelines

Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages

Ctags with Ruby/Rails

We can ctags lots of programming languages. Here is how to do it for ruby/rails. I really like how RubyMine jumps to the source code (either withing project score or to the gem source). This is really useful for reading source code for those classes, methods, modules etc. But Now that I use vim as My IDE/Editor I really like that functionality to happen in my vim editor. And I found ctags as the solution.

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
