# The version that ships with Mac OS X is 
#   /usr/bin/sed
which sed

# Install gnu-sed using Homebrew
# The `--with-default-names` option configures `sed` to use gnu-sed
# Without that option, you'll need to type `gsed` to use gnu-sed
brew install --default-names gnu-sed

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
