About the Authors

Peter Wainwright

Peter Wainwright is a freelance developer and software consultant. He got his first taste of

programming on a BBC Micro and gained most of his early programming experience writing

applications in C on Solaris. He then discovered Linux, shortly followed by Perl and Apache,

and has been happily programming there ever since.

Outside of the software industry, he is a partner of Space Future Consulting, an international

space tourism consultancy firm. He spends much of his free time maintaining the non-profit

Space Future website at www.spacefuture.com and writes the occasional article on space

tourism. He is also an advisor to the board of one or two companies engaged in space tourism

and vehicle development. If you have $50m to spare, he would like to have a word with you.

As well as being the primary author of Professional Perl Programming , he is the author of

Professional Apache (ISBN: 1861003021) , also published by Wrox Press, as well as a contributing

author to Beginning Per l (ISBN: 1861003145) . Formerly based in London, he recently moved

from England to the Upper West Side of New York to be with his new wife, a professional editor,

whom he met through a mutual interest in space tourism and low-rent apartments.

Aldo Calpini

Aldo Calpini is well known in the Perl community for his many important Win32 modules. His

active participation on several mailing lists has helped the Perl language grow in the Win32

community. He began programming twenty years ago and still enjoys hacking every kind of

computer he can put his hands on. He works today as lead programmer in an Italian Internet

startup company.

Arthur Corliss

Arthur Corliss has been programming since buying his first home computer a Timex Sinclair

1000 with a whopping 2K of RAM (which he still has). Having worked his way through several

languages, Perl has become his most frequent language of choice at his latest venture, Gallant

Technologies, Inc., a software development company. On his own time he continues the

madness by working on the Curses::Widgets and Curses::Forms modules, which he

authored and is available on CPAN.
