In this session, we will bring FUN back to Fundamentals as we: * Look at favorite data structures and algorithms from the 70s, 80s, and 90s: where are they today? You won't believe #7! * Discover why hashes aren't just for breakfast. * Discover the Lolrus' favorite data structure (hint: it's got a bukkit). * Discover why some searches gallop and others proceed at a snail's pace. * Face hard truths: sometimes brute force is the best method. * Face harder truths: someone has to maintain the code you write today... and they know where you live. * Face the hardest truth: CPU, Memory, Storage, and I/O are not infinite. And... most importantly... discover the BEST algorithm and the BEST data structure.
