“The problem of where to file: Is it possible to construct the perfect classification system? A truly first-rate hierarchy would not only have all of the characteristics of FN’s hierarchy, but it would also manage to encode the hierarchy in such a way as to eliminate all ambiguity as to where an item might be found. FN comes pretty close… Nobody builds semantically pure hierarchies, it’s just too much work.”

“In any camera that allows you to have control over aperture, the aperture setting is done using what is referred to as F stops. For example, in my Canon G5, the F stops are as follows. 2.0, 2.2, 2.5, 2.8, 3.2, 3.5, 4.0, 4.5, 5.0, 5.6, 6.3, 7.1, 8.0.

“Ajax is an awesome technology that is driving a new generation of web apps, from maps.google.com to colr.org to backpackit.com. But Ajax is also a dangerous technology for web developers, its power introduces a huge amount of UI problems as well as server side state problems and server load problems. I’ve compiled a list of the many mistakes developers using Ajax often make. Javascript itself is a dangerous UI technology, but I’ve tried to keep the list to problems particular to Ajax development…”
