Michael Purvis is a mechatronics engineering student at the University of Waterloo, Ontario. He is a mostly self-taught programmer. Prior to discovering PHP, he was busy making a LEGO Mindstorms kit play Connect 4. Currently, he maintains an active community site for classmates, built mostly from home-brewed extensions to PunBB and MediaWiki. He has written about CSS for the Position Is Everything web site, and occasionally participates in the css-discuss mailing list. He particularly enjoys those clever layouts that mix negative margins, relative positioning, and bizarre float tricks to create fiendish, cross-browser, flexible-width concoctions. These and other non-technical topics are… discussed on his weblog at UWmike.com . Offline, he enjoys cooking, cycling, and social dancing. He has worked for We-Create, Inc. on a number of exciting PHP-based projects and has a strong interest in independent web standards.
