Portfolio

This portfolio represents my best work and supplements my resume.

IBM Linux Technology Center Internship 2006

Genetic Tux Genetic algorithms have been applied to a variety search problems in computer science. It was my task, during the summer of 2006, to apply a genetic algorithm to the O(1) CPU scheduler and dynamically tune it to improve throughput. Although the results of this experiment were inconclusive, the experience of writing Kernel patches, improving the genetic library, working with Jake Moilanen, and going to the Ottawa Linux Symposium secured my interest in the Linux Kernel. Furthermore, I had the opportunity to contribute a number of patches and testsuites for autotest, a new testing framework for the Linux kernel.

NASA Goddard Robotics Internship 2005

This motion history image of my hand represents the great amount of work I put into creating a hand tracking and recognition program while working at Anthrotronix. In ten weeks I had a working demo of tracking a human hand and using that as a computer, or robot, input device.

Also during the internship I had a hand in the design of the electronics and software for ARCHIE, a robot chassis for human interface experiments, which will serve Anthrontronix as a platform for experimenting with their multitude of interface devices. To demonstrate the robot we interfaced it with Anthrontronix’s weapon mounted joystick.

OHSU 9-Button

Reed eVentures and OHSU contacted me in mid-2004 about writing a daemon that would run on Windows, Linux and Mac OS X to control communications between several testing applications and a USB HID device called a 9-button. I worked as a contractor to develop this software against changing requirements and delivered a stable dependable daemon which compiled and ran on all three platforms. Both customers were pleased with the results.

The source code from this project is licensed under the MIT license and can be found here. It is a good example of using libusb, pthreads and sockets; and provides the framework necessary for compilation on the three major platforms.

Bob v2.0

Bob v2.0 robot from shoulders up Developing the software for this project was challenging and fun! Over the course of several months I worked on integrating all of the control and sensor components together into a scripting language, debugging tools and GUI control interface that helped the team win 1st place and Judges’ Choice at the RI/SME competition in Rochester NY in 2003.

Publications

“The 2007 Linux Storage and File Systems Workshop.” A summary of the LSF 2007 workshop I wrote for Linux Weekly News, which aims to be the premier news and information source for the free software community.

“The Humanoid Dream.” In January 2004 I published an article about my high school robotics experience that was accepted by Servo, an internationally distributed monthly robotics magazine.
