Fingerprint in Germany and implemented in both Germany and Japan, the Vucetich system (developed by a Croatian-born Buenos Aires Police Officer) was developed in Argentina and implemented throughout South America, and the Henry system was developed in India and implemented in most English-speaking countries. In the Henry system of classification, there are three basic fingerprint patterns: loop, whorl, and arch, which constitute 60–65%, 30–35%, and 5% of all fingerprints respectively. There are also more complex classification systems that break down patterns even further, into plain arches or tented arches, and into loops that may be radial or ulnar, depending on the
Design Patterns observations were made by Hannemann and Kiczales who implemented several of the 23 design patterns using an aspect-oriented programming language (AspectJ) and showed that code-level dependencies were removed from the implementations of 17 of the 23 design patterns and that aspect-oriented programming could simplify the implementations of design patterns. Paul Graham wrote: There has also been humorous criticism, such as a show trial at OOPSLA '99 on 3 November 1999, and a parody of the format, by Jim Coplien, entitled "Kansas City Air Conditioner".
