Summer of Code

During the summer of 2005, I participated in the Google Summer of Code program, where I worked on the upgrade path from Samba 3 to Samba 4. Details are here. In 2006, I worked on Kerberos support in CUPS. In 2007, 2008, 2009, 2010, 2011 and 2012 I mentored other students for the Bazaar, Samba and OpenChange projects.
