Paul Novitski has been writing software as a freelance programmer since 1981. He once taught himself BASIC in order to write a machine language disassembler so that he could lovingly hack Wang’s OIS microcode. He has focused on internet programming since the late ’90s. His company, Juniper Webcraft, produces HTML-strict websites featuring accessible, semantic markup, separation of development layers, and intuitive user interfaces. He knows the righteousness of elegant code, the poignancy of living on the bleeding edge of wilderness, the sweet melancholy of mbira music, and the scorching joy of raising twin boys.
Tia Gustaff Rayl is a consultant who does development and training in database and Web technologies. Most recently she has published courseware for XHTML, CSS, Java Script, and SQL. It comes as no surprise to those who know her that she began her software career with degrees in English and Education from the University of Florida. As is usual for most newcomers to the field, her introduction to computing was maintaining software. She went on to a long-standing career in the software industry in full life cycle system, application, and database development; project management; and training for PC and mainframe environments. In the mid-nineties she worked on early Web-enabled database applications, adding Java Script to her repertoire. She continues to take on development projects to maintain her code-slinging skills. If she had any spare time (and money) she would go on an around-the-world cruise with her husband and two dogs.
