If you have trouble viewing videos, it's because blip.tv has canceled my account without notification or reason. It may be related to the changes mentioned in this petition.

I have mirrored these locally here in ogg format:

    I've worked in open source software development since 1999. I now work for Canonical on Ubuntu Linux, and I previously worked for Red Hat for 8 years in a variety of roles including embedded systems development, Level 3 support, and as maintainer for their security packages.

    Before that, I worked in many diverse areas, including air defense, 3D graphics driver development, network drivers, development of internet appliances, and Rock and Roll special effects.

    I'm an Electrical Engineer by education, and an amateur radio operator, and my hobby activities are generally related to electronics, amateur radio, and open source software. My call sign in AI4QR, and I'm mostly active on the air on HF. Lately I've been using PSK31 a lot. I'm active in local emergency communications activities. I mostly use Linux in my ham shack.

    My main radio in the shack is a Flex 6700 Software Defined Radio.

    The items marked (ask) are probably for sale to the right buyer at the right price. The right price will not be dirt cheap, but neither will it be outrageous. Contact me if you have an appreciation for these and are interested.
