In his formative years, he worked on high performance cluster computing infrastructure at Worcester Polytechnic Institute. He then went on to implement high availability cluster software such as Kimberlite, Convolo Dataguard, Convolo Netguard, and other solutions in the embedded device space. Jeff has since moved on to a mixed bag of hacking, including the Linux automounter, the netpoll API, Red Hat's netdump utility, and the AIO subsystem.
