We're one of the sites that are having a growing problem lately, generally summarized as "AI attacks". The "Artificial "Intelligence portion of the the Internet are getting funding to develop "search (ro)bots" that hit us with a rapidly growing flood of requests that often swamp our main reasons for being here. We've seen such attacks off and on for the past year, often with the result that our server is unable to keep up with it. If you are getting no response at all, or incomprehensible error messages such as "Internal Server Error", with URLs that sometimes work and other times don't, this may be the explanation. A common symptom is a large number of processes appearing in your server's machine, with the same name rather than just one, when trying to download a file.

Here is my entry in the ongoing competition for most useless web page: JC's decimal to Mayan converter.

The above table shows up with a tiny font size on some browsers. There is nothing at all in the above HTML that specifies a size, and I haven't been able to figure out why some browsers do this. If you have any information on the phenomenon, please send me a message, especially if you have a link to the explanation.

If you can't find something that you expected to find here, try sending me email, and I may be able to put it back.

Here are some of the music and dance groups I'm involved with:
Cambridge Folk Orchestra
International Folk Dance Music.
Roaring Jelly
The Boston area's massed contra-dance band.
Klezmer Contraband
High-energy contradance music with an Eastern flair.
Oivan Ilo
Traditional Finnish music in the Boston area.
Revontulet
Finnish folk dances.

Hidden somewhere on this web site is a picture which almost certainly violates the Communications Decency Act and any other local anti-pornography law in your part of the world. The supporters of such legislation often claim that, if you put something on the Web, "Anyone can get it". The Web is supposedly so insecure that any child can download anything at any time. So I've put a naughty picture here as a challenge: Can you (or any neighborhood child ;-) find it? If you succeed in viewing the picture, please send me a message telling me the text across the top, plus an explanation of how you found it. If you can't find it, you might pass my URL on to anyone who makes such provocative claims, and challenge them to show you just how easy it is by finding the picture.


I've been checking periodically since I put the above up in 1996, and both "ls -lut", and the server logs say that nobody has read my dirty picture since I created it back April 1996. Hey, guys; can't you do better than that!? I mean, it's been 28 years now, and *nobody* has looked at it. It's a nice picture, really! ;-)
