There are a few entries missing from the Ongoing Letter because the server caught a virus. Actually, I made a mistake and opened up an FTP service on it without encryption. I thought, “No one will ever know there’s an FTP site here.” Stupid. Within a week, a virus showed up. I had to reinstate a backup from about two weeks ago. So, students and others, if your web page is not up-to-date, please let me know. Those of you who posted something on your own page, “Sorry!” You’ll have to re-post. Better to be virus-free than to screw around with patching up an infected server.
