Once upon a time Apple had “Develop: The Apple Technical Journal”, which was a phenomenal printed magazine put out by Apple Engineers and DTS specifically targeted at Apple Developers. It was in print quarterly from January 1990 to March 1997 with 29 editions, most of which were over 100 pages long and were chock full of high quality technical information about Apple’s platforms. The Winter 1992 edition introduced “Kon & Bal’s Puzzle Page” which was written by the infamous Konstantin Othmer and Bruce Leak (with occasional guest writers). It was always done in the form of a dialog between engineers as they solved a problem. It was my favorite part of Develop even though I don’t think I ever scored higher than a zero. Recently we stumbled upon something that we thought was worthy of a Puzzle Page, and hopefully KON and BAL will appreciate this homage.
