Custom recipe to get OS X 10.10 Yosemite running from scratch, setup applications and developer environment. I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install. On average, I reinstall each computer from scratch every 6 months, and I do not perform upgrades between distros.
This keeps the system performing at top speeds, clean of trojans, spyware, and ensures that I maintain good organizational practices for my content and backups. I highly recommend this.

Sometimes you need to iterate over a ton of items and you don't want the overhead of creating AR objects out of all of them. Hell, you only need a few things! Well, #pluck has your back.
But what if you want to iterate over many tonnes of items?
Pluck in batches to the rescue!
This isn't the exact code that I use in my code base, but it is damn close.
This is a collection of links, examples and rants about Presenters/Decorators in Rails.
The "Decorator" pattern slowly started gaining popularity in Rails several years ago. It is not part of core Rails, and there's many different interpretations about how it should work in practice.
Jay Fields wrote about it in 2007 (before he switched back to Java and then Clojure): http://blog.jayfields.com/2007/03/rails-presenter-pattern.html
I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!
