The Sad End of Intel Desktop Boards
As previously discussed on this blog, Intel decided to quit the desktop board business in 2013. What has not been discussed is how Intel treated the buyers of the last generation (i.e. 8-series Lynx Point chipsets) of those boards.

How Not to Die (2007)
August 2007 (This is a talk I gave at the last Y Combinator dinner of the summer. Usually we don't have a speaker at the last dinner; it's more of a party.

Audio Processing for Dummies
In my spare time I’m an emergency services volunteer, and one of the tasks our unit has is to run the radio network and keep track of what’s happening.

Rust 2020: GUI and Community
In response to the call for blogs about the vision for Rust for 2020, I’m going to write about GUI. I believe the time is right for a native GUI toolkit written in Rust, and that such a thing would fill a very important niche.
