The death of the utility belt

Some quick notes of my two weeks living by the unix philosophy.

Things like underscore, jquery, backbone, bal-util, etc are on the way out
They were awesome at their time, because until recently, packaging and distributing javascript code was hard
- pre-compile, pre-package, distribute as zip, manual install
These days, we have npm, component, bower which can automate all distribution, packaging, installation, and concatination of different projects regardless of size
Things like node's require (browserify for client side), make it finally easy for modules to include each other
- Before we had to battle with global variables and lengthy manual installs to get two libraries working together, don't forget version conflicts
