Vim Regexes

When do I need a backslash?

• this is all dependent on the "magic" option being set to the default, magic (:set magic? will tell you what you're set on)

• vim regexes are beyond reason

• (defn finds a literal paren, and \(defn\) creates a group.

• | finds a literal pipe and, \| separates alternatives

√ gcc can’t find stdio.h (& similar) - /usr/include got blown away
xcode-select --install
see https://github.com/mxcl/homebrew/issues/20427

√ java install got blown away & replaced with a stub that says to download java

# General comment: I assume here that I'm just doing it wrong as I haven't been using Arel that long. 
#   If I knew for sure this was broken I'd just file a bug instead.

# Note that these specific ActiveRelations are just a trimmed-down example; the actual use case would 
#   really be better with a UNION, I promise.
