Learning Perl on Win32 Systems

Randal L. Schwartz is an eclectic tradesman and entrepreneur, making his living through software design, technical writing and training, system administration, security consultation, and video production. He is known internationally for his prolific, humorous, and occasionally incorrect spatterings on Usenet -- especially his "Just another Perl hacker" signoffs in comp.lang.perl. Randal honed his many crafts through seven years of employment at Tektronix, ServioLogic, and Sequent. Since 1985, he has owned and operated Stonehenge Consulting Services in his home town of Portland, Oregon. Randal is not new to O'Reilly. He is author of Learning Perl and co-author of Programming Perl, which he wrote with Tom Christiansen and Larry Wall, the creator of Perl. Erik Olson is a renegade linguist who makes a living developing software for Win32 platforms. Since 1994, Erik has been director of advanced technologies for Axiom Technologies, LC, a software outsourcing shop. Erik delivers developer training, system administration, and program/concept development for a number of large-scale horizontal and vertical applications. Working as a program developer since 1986, Erik has implemented a variety of systems ranging from point-of-sales systems to horizontal PIM products to real-time financial market applications. Although much of his work is done in C++, he has particular interests in interpreted languages and ActiveX scripting. Erik earned a B.A. in linguistics from the University of Utah and pursued graduate studies in Arabic linguistics there and at the University of Washington. Tom Christiansen is a freelance consultant specializing in Perl training and writing. After working for several years for TSR Hobbies (of Dungeons and Dragons fame), he set off for college where he spent a year in Spain and five in America dabbling in music, linguistics, programming, and some half-dozen spoken languages. Tom finally escaped UW-Madison with B.A.s in Spanish and computer science and an M.S. in computer science. He then spent five years at Convex as a jack-of-all-trades working on everything from system administration to utility and kernel development, with customer support and training thrown in for good measure. Tom also served two terms on the USENIX Association Board of Directors. With over fifteen year's experience in UNIX system administration and programming, Tom presents seminars internationally. Living in the foothills above Boulder, Colorado, surrounded by mule deer, skunks, and the occasional mountain lion and black bear, Tom takes summers off for hiking, hacking, birding, music making, and gaming.
