# Mac fix 1 - Install the Nokogiri gem on Mac OS 10.9 Mavericks
#
# Usage: to configure and install using Bundler, pass in 'bundle' as an argument to the script.
#
# Nokogiri works at a very low level, so it has many issues on various platforms.
# As a result, the command `install gem nokogiri` often will fail. This fix is for
# errors involving 'libiconv', such as the following one I encountered:

redis auto start OS X

Install with Homebrew

brew install redis

Set up launchctl to auto start redis

$ ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents

/usr/local/opt/redis/ is a symlink to /usr/local/Cellar/redis/x.y.z (e.g., 2.8.7)

A lighthearted and overly flattering comparison of R to other programming languages: what other comparisons have I missed?

R is like:

  • Clojure, because most objects are immutable
  • Scala, because it combined functional and OO techniques
  • Node.js, because the interpreter is single threaded
  • PHP, because it favours pragmatism over purity
  • Lisp, because it's homoiconic
  • Perl, because OO is (mostly) implemented using the language itself
