all right, so it is my very great pleasure to be here with ellen ullman. she is i'm just going to read a little of her bio. she wrote her first computer program in 1978 commit on top a 20 year career as a programmer and software engineer. her essays and books have become essential reading in describing the social, emotional and political effects and personal effects of technology in our lives. she is author of two novels, by blood, and the bug which was a runner-up for the hemingway awarded the first book was in times notable book. the book would talk about today is tritone -- >> no. >> that was her previous memoir. forgive me. what we talk about here is "life in code", a personal history of technology. we go way back. i edited her at "harper's magazine" when i was an editor there. she was writing about technology. i was an editor at one of the oldest magazines in the country, a stored print publication and now we're kind of switched roles. now i am an internet editor for "the intercept," and she's a novelist and distinguished memoirist. so interesting how
