Rich Hickey Q&A by Michael Fogus

Best known as the inventor of Clojure, a Lisp that runs on the Java Virtual Machine and the first new member of the Lisp family to attract any widespread interest since Scheme and Common Lisp, Rich Hickey has been a software developer and consultant for two decades.

Prior to starting work on Clojure, he made four attempts to combine Lisp with either Java or Microsoft’s Common Language Runtime: jfli, Foil, Lisplets, and DotLisp but Clojure was the first to draw significant attention. To date there have been four books published on Clojure, including The Joy of Clojure by interviewer Michael Fogus. The first Clojure conference, ClojureConj held in 2010, drew over two hundred attendees. And the Clojure Google group has, as of this writing, 4,880 members who have posted over 46,000 mes

Prerequisites

Clojure Destructuring Tutorial and Cheat Sheet

(Related blog post)

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

Installing Cassandra on Mac OS X

Install Homebrew

Homebrew is a great little package manager for OS X. If you haven't already, installing it is pretty easy:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Setting Up Clojure on OS X

I spent a lot of time trying to find a pretty optimal (for me) setup for Clojure… at the same time I was trying to dive in and learn it. This is never optimal; you shouldn't be fighting the environment while trying to learn something.

I feel like I went through a lot of pain searching Google, StackOverflow, blogs, and other sites for random tidbits of information and instructions.

This is a comprehensive "what I learned and what I ended up doing" that will hopefully be of use to others and act as a journal for myself if I ever have to do it again. I want to be very step-by-step and explain what's happening (and why) at each step.
