I led a
barcamp philly session today titled
MAMPCamp: testing websites on your own Mac. You can find
considerably expanded slides, notes and links here.
I've also promised to deliver a complete writeup on how to use dnsmasq to let coworkers easily view each others' test sites. More importantly, I've promised to deliver Z-CAMP (Zero-Configuration Apache MySQL PHP), a really
really easy way to set up and test sites on your Mac. That should be along in a few weeks.
