Ralph, a middle-aged geek, currently works as a "Enterprise Unix/Linux Engineer", and in the past at times as engineering physicist, CADD/CAE administrator and manager, project scheduler, software engineer / coder.
He has loved encyclopedias since the age of five. He lives in a northern suburb of Chicago with wife and kids. Hobbies include electronics, computers, photography, reading, bicycling and other exercise to combat middle-age spread.
He's finally obtained a wikipedia account as an upgrade to a couple years of anonymous editing, and is cooking some articles on subjects not yet in Wikipedia.
