The mathemagician and pied puzzler : a collection in tribute to Martin Gardner ; [the first Gathering for Gardner (G4G1) was held in January 1993, Atlanta ; a second gathering was held in January 1995 ; a third in January 1998

This volume comprises an imaginative collection of pieces created in tribute to Martin Gardner. Perhaps best known for writing Scientific American's "Mathematical Games" column for years, Gardner used his personal exuberance and fascination with puzzles and magic to entice a wide range of readers into a world of mathematical discovery. This tribute therefore contains pieces as widely varied as Gardner's own interests, ranging from limericks to lengthy treatises, from mathematical journal articles to personal stories. This book makes a charming and unusual addition to any personal library. Selected papers: - The Odyssey of the Figure Eight Puzzle by Stewart Coffin - Block-Packing Jambalaya by Bill Cutler - O'Beirne's Hexiamond by Richard K. Guy - Biblical Ladders by Donald E. Knuth - Three Limericks: On Space, Time and Speed by Tim Rowett.

Security is a growing duty of the everyday system administrator. While there are certifications and specialized (expensive) training classes, there is not a go-to-off-the-shelf resource to tackle these obstacles. With a large and growing number of system administrators worldwide, security is quickly becoming one of the weakest areas in their skill set, but one of the most necessary. This book helps bridge the gap for this occupation.
