Bio
Æleen Frisch has been a system administrator for over 20 years, tending a plethora of VMS, Unix, and Windows systems over the years. Her current system administration responsibilities center on looking after a very heterogeneous network of Unix and Windows NT/2000/XP systems. She is also a writer, lecturer, teacher, marketing consultant and occasional database programmer. She has written eight books, including Essential System Administration (now in its third edition), Essential Windows NT System Administration and the Windows 2000 Desktop Reference (all from O'Reilly Media, Inc.) and Exploring Chemistry with Electronic Structure Methods (Gaussian, Inc.). Currently, she writes the "Guru Guidance" column for Linux Magazine. She also writes poetry and is currently working on her first novel.
