Hey Scott, this is the hacky highlighting I did with code snippets in showoff.

Refer to http://i-dont-trust-your-code.heroku.com/ for the presentation and http://github.com/jtrupiano/i_dont_trust_your_code for the code.

In this first example, I am successively highlighting lines of code from a source file. Refer to slides 22-28 in the presentation and 2-environment/3-custom-require.md in the source.

In the second example, I am highlighting lines of code from irb and shell sessions. Refer to slides 6-13 in the presentation and 2-environment/1-environment.md in the source. What I'd really like to be able to further do is highlight individual results from the ls commands on slides 8 and 10, but that was going to b

# Process used to ammend a commit way back in my log (to eliminate some sensitive information)

# Print the git log to a temp file
git log --pretty=oneline > git.log

git checkout -b new_branch SHA
# edit and ammend
git commit -a --amend

# Use sed to reverse the lines in the file
