It's amazing what a couple of days of bed rest and some intake of antibiotics can do for a sick man. By yesterday afternoon, my energy was really returning. I took it easy, but I was able to head to the stables and watch my daughter ride. It was a good day.

John Cook has published a nice article on The Code Project: Five Tips for Floating Point Programming. It's a good refresher article, with some deeper implications if you really want to get into numerical analysis. Here's the blog article and discussions. I have some circa 1970 references if you want to go further. Hopefully someone will take pity and add some modern references:

• First Principles Of Numerical Analysis, Burton Wendroff, 1969, Library of Congress Catalog Card No. 69-16406
• Numerical Analysis, A Second Course, James Ortega, 1972, ISBN 0-12-528560
