My beautiful and talented wife's latest research topic has to do with protecting private information in a database from the developers that work on it. Her paper and source code are now available at:
http://rubi.excess.org/

Her paper was accepted to the Montreal IEEE conference this year, but unfortunately due to other obligations she will not able to present her research.

It has been an wonderful and eventful summer and I must thank my friends and family for helping me through it. I am, however looking forward to settling back into my routine and getting back into some of the projects that have been languishing. This beautiful weather makes it hard to stare at a computer for hours on end... Maybe I should move to Finland (or at least rent Night on Earth again.)

The recommended way of installing Django sites is to use mod_python. mod_python allows Apache to serve content much more quickly than CGI, but using it can create problems that are difficult to debug.

mod_python embeds the python interpreter in Apache and can share python interpreters between virtual hosts. This means that a misbehaving Python program can do much more damage than it could if it was running as a CGI script.

Mailman had me scratching my head for some time this weekend while I was trying to figure out how to change the URLs generated it its administration site. It turns out that Mailman copies configuration information into its list data at list creation time and then ignores changes to its main configuration file.

Django comes with an amazingly powerful database API that does a very good job of hiding database-specific SQL. Sometimes, though, the API doesn't do exactly what you expect. I ran into this when developing the code that displays the “Tags” that have stories posted.

Fortunately, there is a fairly easy way to get down to the SQL and see what is happening when something goes wrong.
