[b]Daniel J. Barrett[/b] (born 1963) is a writer, software engineer, and musician. He is best known for his technology books, his work with progressive rock band Gentle Giant, and the imaginary computer game BLAZEMONGER. Barrett has written a number of technical books on computer topics. The most well-known are Linux Pocket Guide and SSH, The Secure Shell: The Definitive Guide. His books have been translated into Czech, French, German, Hungarian, Italian, Japanese, Korean, Mandarin, Polish, Portuguese, Russian, and Spanish. Barrett, author of the book MediaWiki, has received media coverage for his deployment of MediaWiki in corporate environments. In the 1990s, Barrett created the concept of BLAZEMONGER, an imaginary computer game for the Commodore Amiga, which spoofed the computing industry, and he wrote approximately 100 articles about it. In 1988, Barrett wrote and recorded the song "Find the Longest Path," a parody incorporating an NP-complete problem in computer science and the frustrations of graduate school. It has been played at mathematics conferences, incorporated into several YouTube videos by other people, and independently performed by a choral ensemble at ACM SIGCSE 2013. Computer scientist Robert Sedgewick ends his algorithms course on Coursera with this song.
