coding conventions

• Use 2 space indents
• NO tabs - anywhere
• try not to leave trailing whitespace
• prefer parentheses around method arguments - ESPECIALLY when the argument list has more than one argument.
• Optimize your code for READABILITY first.
• always put whitespace between successive elements of a list (e.g. argument list, array)

Version Control with Git

• Commit locally very often - you can always rearrange it later.
