Note to site visitors:
this website is a time machine, left pretty much in the exact state it was in at the end of 2006, when site editor and publisher Daniel Read retired from working on it. Please enjoy the 100% free, ad-free content, most of which is still relevant, as developer.* was always dedicated to the "timeless" aspects of technology and software work. Regretfully, as of this writing, the "Community" side of the site, which featured blogs and article comments, has not be restored after a database corruption occurred in the Drupal MySQL database. (If any Drupal experts out there would not mind helping me get it back online, I would accept the help.) Most if not all of the blog/comment content should still be available in the Archive.org Wayback Machine. Thank you to everyone who supported or contributed to this site in it's 2000's heyday. This one of the first sites of its kind. (We even had a theme song
!) Please check out the "About" page for more information about how the site was put together from a technical standpoint. --All the best, Dan. (If anyone would like to get in touch, please find me on LinkedIn.)
Interface Oriented Design Book Excerpt: Inheritance and Interfaces (Chapter 5)

Test Smarter, Not Harder
When we’re testing any software, we are faced with the tradeoff of cost and benefit of testing. With complex software, the costs of testing can grow faster than the benefits of testing. If we apply techniques like the ones in this article, we can dramatically reduce the cost of testing our software. This is what we mean when we say test smarter, not harder.
The Many Flavors of Testing (An Excerpt from Software Conflict 2.0)
Once we realize that we are committed to a future full of testing, it is worth exploring what testing really means. I would assert that there are several flavors of testing, and that all too often when we speak of testing we consider far too few of those flavors. An excerpt from Software Conflict 2.0.

Personal Chemistry and the Healthy Body
