This book goes into what is overlooked and should be taught in "computer science" classes. Instead of focusing on conspiracy-driven "good programming practices" with trite and bloated algorithms, this book focuses on efficient, simple, and creative solutions to problems. This emphasizes on creating solutions that work well on COMPUTERS (albeit dated computers) and not abstract turing machines with no disk or memory limitations! Programming Pearls is easy to read, with lots of little excersizes to get your brain thinking for FUN and PROFIT. This book truly has SLACK.
