I've had a web page for several years now, but I still regard my scientific
publications to be my most important publishing outlet because it has an
archival value and peer review (unlike the web). Some say that personal web
pages are passé now, but I disagree. Personal web pages are one of the
profound social changes that we are witnessing - the resurrection of the
political leaflet, the small business, and the individual. It's a remarkable
outlet for free speech, and can fundamentally change the social fabric of the
world.
I'm convinced that the traditional media is afraid of the information revolution, and perhaps they should be. They seem to not understand personal web pages and usenet (see dejanews), and are horrified at the new media that they can't control in the same way they always did before. Oh dear! What if people decided to express themselves directly without our editorial conservatism? What if a diversity of opinions could be heard? How untidy!
Like most geeks, I started out my web site a few years ago with some technical information on the web. In the future I expect that all such academic technical information will be available on the web, although the economic mechanism for supporting an industry to edit, distribute, and archive such information is unclear at this time. Most of my technical information is published papers, but I also maintain a list of cryptography-related web sites. I also have a thought of the day, and a collection. It's mostly famous quotes.
As a scientist, I have most recently been reminded of my government's inability to deal with the realities of the information age, leading me to compose an observation about politics. This is a bit of a rant, but the issues are very serious and fundamental to the nature of a free society. As a researcher in information security, I feel an obligation to lead through example on the subject, so I've drafted a statement on freedom and responsibility for cryptologic researchers. I'd like to hear what you think about it.
I've been a professor at three universities, and recently taught a course in cryptology. If you're trying to learn the field, I recommend against trying to solve my $100 challenge (I think it's too hard). Instead, you might find it entertaining to look at a cryptographic mystery from China. Education is something that I seem to still spend time on, through various discussions and lectures. It may seem strange, but I started a tongue-in-cheek criminal web site called DigiCrime, Incorporated as an educational mechanism. People sometimes remember a joke better than a technical explanation. At any rate, it stimulates their thinking.
