Ron Jeffries has been developing software longer than most people have been alive. He holds advanced degrees in mathematics and computer science, both earned before negative integers had been invented. His teams have built operating systems, compilers, relational database systems, and a large range of applications. Ron’s software products have produced revenue of over half a billion dollars, and he wonders why he didn’t get any of it.
Ron is an author of the Agile Manifesto, having been part of the Agile movement before it was even named Agile. His web site www.XProgramming.com is in the process of moving to ronjeffries.com, where his newest writings will be found, as well as all the material from the XProgramming site.
Ron’s most recent book, The Nature of Software Development, was released in December 2014 by Pragmatic Programmers.
