Coyote's Guide to IDL Programming is the personal web page for retired IDL expert David Fanning and his alter ego, Coyote. You are never sure what you are going to find here, but it is always guaranteed to be fun, interesting, or vaguely related to IDL*. The site is especially well known for its IDL Programming Tips, and for its well-written and documented IDL programs, including the programs in the powerful Coyote Graphics System. You can also find the most important article ever written about IDL, JD Smith’s famous explanation of the all-powerful Histogram command: “Histogram: The Breathless Horror and Disgust”. Fanning retired from updating the site and became a professional hiking bum in November, 2014. You can follow his exploits with Coyote on his Rawah Ranger writing blog.


David is the author of several books on IDL programming, including Coyote's Guide to Traditional IDL Graphics and IDL Programming Techniques. Coyote is a poet and ne'er-do-well who has been associated with Fanning for over 25 years. He is the past Chairman of the IDL Expert Programmer's Association, a once famous, but now debauched, association of lecherous programmers known as the “dinosaurs.”

Coyote's Guide to IDL Programming is a resource for people who want to learn more about IDL. This is what Mark Hadfield, an IDL user in New Zealand, had to say after he spent some time poking around here:

Your IDL programming site is a BLOODY TREASURE, what we call in New Zealand a "taonga". Excelis should pay you a great deal of money for turning their powerful but cranky data analysis system into something useful, approaching elegance.

Alas, there's no money in it. But I do enjoy hearing from people who read it. Enjoy!
