Linuxcare Inc has named Andrew Tridgell, the Australian academic and team leader for Samba, to the position of senior researcher. Samba provides a complete replacement for the networking services included in Windows NT, OS/2 Warp, Sun NFS and Novell NetWare servers, letting Linux perform in their place. Samba is a virtually ubiquitous open source application, depended upon by almost every Linuxcare customer, explained Linuxcare chief technology officer David Sifry. All this makes Tridgell is something of a catch. He will continue to serve as Samba team leader and will remain a visiting fellow at the Australian National University.
