    Random by Bart Massey

    Randomness is philosophically interesting and really important to technologists. I will survey a bunch of random stuff, including:

    Applications of randomness, including cryptography and game theory (they’re related). A hypothetical Poker server will be a running example.

    Various definitions of “random”, including one good one and several bad ones used by most software people.

    Pseudo-random number generators (PRNGs). Hardware random number generators, including entropy gatherers. I will show an open-hardware open-source high speed true random number generator built by Bdale Garbee and Keith Packard that I’ve been involved with, which will provide 12Mb/s of random bits through a USB port for about $15.

    Statistical tests of randomness and how various popular PRNGs fail.

    Randomized algorithms, including my well-polished minitalk on The Perfect Shuffle and a discussion of “Telephone Poker”.

    Participants will write code for a couple of popular PRNGs and evaluate their performance during the session.

    If you want to understand randomness better (and you should), this is the talk for you.

    ACM Event: Common Lisp

    What is Lisp? What is Common Lisp? Lisp is the second oldest high-level programming language in today’s world. Lisp/Scheme are the favored programming language toward Artificial Intelligence applications and are an extremely valuable learning experience. Programming in a functional language like Lisp will help you think.
