Freeelance author for Linux Journal.

Featured columnist in Linux Format magazine, a UK publication from Future Publishing. I write a monthly tutorial for end users that covers the use of the GNU Image Manipulation Program with ocassional trips into other graphics related topics.

Senior software engineer working on next generation computing systems for government subcontractor. Duties include source code management from Kernel on up to applications, coding and debugging of network drivers, performance benchmarking of embedded Linux kernel based on MontaVista MIPS distribution, build management, API design and implementation for hardware interfaces, design reviews, and tool development. This is a small group and the only thing I haven't yet touched is the CFE (a BIOS replacement) code and the oscilliscope. But CFE, at least, may be on the long term plan.
