My box which did mail and web services was down for 1 or 2 months at the start of the year. Email was quickly rerouted with the help of friends. UUCP still is useful. Web services where not brought operational that fast because I just didn't care.
I started a very small ISP with a few friends. Our main intention is to even more extend our knowledge of the tools involed. I hacked up some nice configuration scheme which keeps everything (configuration for Apache, Postfix, PostgreSQL, MySQL, courier-{imap,pop3}, etc.) in OpenLDAP. Authentification/NSS against LDAP is done with nss_ldap/nss_nss.
We wanted to setup some distributed network filesystem too. Coda didn't really work that well. Maybe it's just that the current 5.3.18 is broken. Perhaps we were too stupid. Who knows? Next thing to check out is OpenAFS or Intermezzo.
I started work on a pinging software for anonymous remailers: echolot. CVS is up on savannah if you're interested. ATM it already fetches keys and confs from remailers, send and receive pings. The only problems I'm facing is interoperability between GnuPG and the remailing software deployed: mixmaster and reliable.
I'm also writing a remailer daemon in Perl. It will handle both type I and type II messages when it's done. At the moment it can only build type II (aka mix) messages. I don't even have a name for it yet.
Florian Reitmeir and me developed a pretty printer or source code indenter for PHP! Since there obviosly exists no such thing on the internet we stepped forward and had a good time. The result was php indent. Don't try it if you're in a hurry or expect it to not corrupt your code. It's really slow and not properly tested.
I also updated my projects site.
For university I'm doing some interesting stuff with OpenVRML on MacOS X. The only thing I know for sure now is that openvrml lacks documentation.
FOAF updates: Trust rankings are now exported, making the data available to other users and websites. An external FOAF URI has been added, allowing users to link to an additional FOAF file.
