Past and ongoing projects and patches:

• ongoing: novylen.net - hosting domains, email, webmail, file storage, image gallery, and various other services for friends and family. About 50 users. Innumerable little scripts and customizations.
• 02-2006: Fixed Christophe Saout's qmail-smtpd SPF patch for better logging.
• 02-2006: qgreylist-mysql - A rewrite of Jon Atkins' qmail greylisting script, to make it use MySQL instead of flat files. Among other things, this allows multiple hosts to use the same greylist database.
• 10-2005: Pody Positive (with Ken Phing) - a personal trainer customer management system; billing, statistics tracking, messaging, personal notes on files; written to requirements for a client.
• 07-2005: SDKP - a simple "DKP point" system for World of Warcraft; this set of scripts allows a Warcraft guild leadership to distribute earned "loot" through a collection of players.
• 03-2005: spam-scan and innocent-scan - A set of scripts that scan Maildirs for misclassified DSPAM-classified emails; this allows users to "report" emails by moving them to the correct folder if misclassified as spam "false positives" or "false negatives".
• 08-2004: SRBL - a Realtime Black List for email servers, designed to use data fed from arbitrary, anonymous Bayesian spam classifiers in order to decide whether to block an IP, using trust algorithms to decide which data to accept. Deprecated in favour of Jonathan A. Zdziarski's "DSPAM" RBL, which has since been left undeveloped. So I might start work on this again.
• 05-2002: snapshot - A shell script to handle live incremental system backup snapshots, accessable to users.
