The other day’s blog post and a recent Andrew Binstock interview of Donald Knuth made me think more about how the ACM is really not serving the interests of computer science. Continue reading I know, I am the one being a jerk
“Sorting Used in Anger” (A rambling glimpse into the mind of a theorist)
Author: John Mount
The other day I had a bit of time to kill before an appointment. Luck was with me: there was a nearby bookstore and I was able to pass some of the time skimming through a book called “Beautiful Code.” Everything started out fun and nostalgic. The book title reminded me of “The Art of Computer Programming” (a book that probably did as much through the grace of its title as it did through its incredible contents to attract minds into theoretical computer science). One of the chapters of “Beautiful Code” was by Jon Bentley (a hero of sharp reasoning and clever coding) and as I flipped to the chapter my day was ruined. There it was: Quicksort an algorithm that I have a long love and hate relationship with.

“A second goal of 23andMe [is] to collect a large database of genetic information and then come back to you over time with invitations to provide specific health data and participate in research.”
23andMe Board member Esther Dyson
Unregulated companies managing personal medical records is going to be very bad for very many people. You will not be invited to share in research profits, you may be un-invited from your insurance and your job.
We are being asked to believe that shared access to our personal health records is an unambiguous direct benefit to us. Perhaps, if properly regulated this is true. However, huge companies want to implement online medical record platforms without any public policy discussion. And even what little debate is attempted is stilted and irrelevant because the value of medical records is accepted without examination and criticism is limited to identifying a few pet risks.
Hello World: An Instance Of Rhetoric in Computer Science

Computer scientists have usually dodged questions of intent, purpose or meaning. While there are theories that assign deep mathematical meaning to computer programs we computer scientists usually avoid discussion of meaning and talk more about utility and benefit. Discussions of the rhetorical meaning of programs is even less common. However, there is a famous computer program that has a clean an important rhetorical point. This program is called “hello world” and its entire action is to write out the phrase “hello world.” The action is simple but the “hello world” program actually has a fairly significant purpose and meaning.
I would like to briefly trace the known history of “hello world” and show how the rhetorical message it presents differs from the rhetoric embodied in earlier programs. In this sense we can trace a change in the message computer scientists felt they needed to communicate (most likely due to changes in the outside world).

I have finally written up and released a paper in PDF: Automatic Generation and Testing of Trades describing a lot of the statistics and optimization methods used when I was technical trading on a Banc of America Securities proprietary program trading desk. It was a very exciting time.

Nina and I just finished up our analysis of some of the statistical difficulties encountered by users of Google AdSense. It came out a bit long- but we found the right statistical reference to prove that there are real barriers to understanding in this market. The paper is most legible in PDF, but we also include an HTML version so the blog entry can be skimmed.
