Biography
Philip Tellis is a geek who likes to make the computer do his work for him. As part of his job with the Performance and Security teams at Yahoo! he analyses the impact of various design decisions on web application performance and security. He also maintains the javascript implementation of strftime used in YUI and plays around with security, accessibility and i18n. He is the maintainer of several opensource projects including ayttm and libyahoo2, and most recently, boomerang — a real user web performance measurement tool.
In his spare time, Philip enjoys cycling, reading, cooking and learning spoken languages.
Philip has spoken at several conferences in the past, including FOSS.IN, FREED.IN, Ubuntulive, Linux Symposium, PHP Quebec, Opensource Bridge, WebDU, FOSDEM, IPC and ConFoo.

This talk will go into some of these tricks we developed while building boomerang.

How do you parse and validate a date? What about an email address? A URL, phone number, postal code? How do you quickly search through a file for something that you only know a little about? Regular Expressions, that's how.
