Does it really make sense to optimize for a 1.01x speed improvement by using single-quoted strings instead of double-quoted Strings in Ruby (to avoid interpolation scanning in the double-quoted strings)? I think the answer is no.

Prerequisites:
- One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
- A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.
