Why I love zsh (and hate being forced to use bash)

Smarter completion:
cd tab completion -- directories only
bash can do this, but needs the bash-completion package, usually comes separately
zsh always comes with completions, why doesn't bash?
Filename correction during completion
if dir1/x exists and dir2 exists, then "dir/x<TAB>" completes to dir1/x
if name1 is a file and name2 is a directory with files in it, "name/<TAB>" completes to "name2/"

A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

	# This way we re-query the app itself in order to avoid sequential execution for CPU-intensive tasks
	# that can (and should) be executed in parallel.
	#
	# Pros: decent scalability can be achieved by assigning path=some.load.balancer.com (i.e. Amazon ELB)
	# and putting a bunch of multicore machines behind it.
	#
	# Cons: we lose some fraction of time on JSON encoding/decoding and HTTP traffic.
	# Load-balanced fault-tolerant DRb could be a better choice, but would require more work and provide only
	# minor performance improvement in situation where JSON/HTTP aren't the main CPU consumers.
