I work in Solaris Kernel Development at Sun Microsystems, where among other things I'm
the architect for RAS (Reliability, Availability, Serviceability) features in Solaris.
My research and engineering interests are focused on technology to enhance the availability of
computer systems,including programming languages and debugging tools for developers, operating
system technologies for handling and recovering from software and hardware faults and defects,
and tools for administrators and users that improve the user experience.
My work at Sun includes the design and implementation of:
as well as contributions to the design of coreadm(1M), user core files, kernel crash dumps, the /proc filesystem, and other related areas. In Solaris 10, I designed and implemented the D programming language and compiler for DTrace, and led the effort to create Sun's architecture for Predictive Self-Healing, part of our innovative approach to Fault Management that is debuting in Solaris 10.
Contrary to earlier blog easter-eggs, I resemble neither the battering-ram power of Bosco Baracus nor the pasty-haired impishness of Larry Fine. I do, however, look pretty much exactly like my cartoon action figure, as seen in InsideJack Episode 2.
Prior to working at Sun, I was causing trouble with my partner-in-crime Bryan Cantrill at Brown University, where I received a BS and MS in Computer Science. I'm originally from the Boston area, and spend much of my free time reliving basketball games from the 80's now on DVD, this year's Red Sox triumph, and the weekly drama of a Man Named Brady.
