Some notes on why I have chosen some of these preferences:
I am primarlily a Ruby web developer, and work on a variety of Ruby and Rails versions and database platforms.
I usually use RVM (http://rvm.beginrescueend.com), but this guide uses [chruby](https://github.com/postmodern/chruby)

I spend most of my day in the Terminal, Atom editor, and a Web Browser, and desire to keep things as simple and stock as possible, but do have certain minor preferences that make my day-to-day interaction with the computer better.

Choose Full-Disk encryption on Install and set a password
Run software update until it cannot find any updates

There doesn't seem to be a good resource online describing the issues with protocol buffers and deterministic serialization (or lack thereof). This is a collection of links on the subject.

Protocol Buffers v3.0.0. release notes:

The deterministic serialization is, however, NOT canonical across languages; it is also unstable across different builds with schema changes due to unknown fields.

Maps documentation:

Wire format ordering and map iteration ordering of map values is undefined, so you cannot rely on your map items being in a particular order.
