I would like to add that Jack wite regularly for The Embedded Systems Programming magazine regularly and those articles are available online at:

http://www.embedded.com/mag.htm or
http://www.embedded.com/

Also, I read his book titled "The Art Of Designing Embedded Systems", and found it very useful. It's full of embedded development tips and tricks. If you happen to be reading his articles at Embedded Systems Programming, most of the topics covered in the book will be familiar, though.
