# Monitor HTTP requests being made from your machine with a one-liner..
# Replace "en1" below with your network interface's name (usually en0 or en1)
sudo tcpdump -i en1 -n -s 0 -w - | grep -a -o -E "Host\: .*|GET \/.*"

# OR.. to be able to use as "httpdump" from anywhere, drop this into ~/.bash_profile:
# (again replace "en1" with correct network interface name)

# This is a useful little pattern for working with gems without
# explicitly requiring rubygems in your code.
#
# The approach taken is to require a library and catch any LoadError
# that might get thrown. In the rescue clause we require rubygems.
#
# The require method is nice in that it will return true if the code
# was loaded, and it returns false if the code was _already_ loaded.
# If the require of rubygems returns true, we will retry our original
# require. It will either succeed this time (since we now have rubygems

Poor Man's Deploy

• Start a Sinatra server on port 4000
• GET / to that server triggers a git pull and mod_rails restart
• Hit port 4000 locally after pushing

Why?
