Sandra Henry-Stocker has been administering Unix systems for more than 18 years. She describes herself as "USL" (Unix as a second language) but remembers enough English to write books and buy groceries. She currently works for TeleCommunication Systems, a wireless communications company, in Annapolis, Maryland, where no one else necessarily shares any of her opinions. She lives on a small farm on Maryland's Eastern Shore.
