These days, I've got my head in the realm of EdTech and making effective use of educational data to help teachers improve student outcomes in their classrooms. I am a proud member of the five-person leadership team of Double Line Partners, an education data consulting company.
I co-authored a book on Web development in a Linux+Apache environment. My content focused on AJAX. Professional LAMP: Linux, Apache, MySQL, and PHP. Gerner, Owens, Naramore, Warden. December 2005. Wrox/Wiley Publishing.
I'm also a Neuroscience geek. I am a former researcher at Dr. Stephen Berry's Behavioral Neuroscience Lab at Miami University, where I engaged in electrophysiological behavioral experiments with rabbits.
There's also the sandbox, but some examples will no longer run on the new server.
