One of the disturbing mindsets in software development and web design today, is the sacrifice of practical concerns in favor of theoretical constructs.<\/p>\n
Case in point:<\/strong><\/p>\n Recently a young friend of mine (who is studying computer engineering,) told me an interesting story about a class project where each student had to produce a piece of software … the results, and the professors reaction to the results, are interesting.<\/p>\n Sad but true:<\/strong><\/p>\n When all things were said and done, only one student was able to produce a working application. The irony was that this student got a failing grade because his code did not meet certain theoretical constructs! <\/p>\n The above example illustrates a problem in the way many programmers think: putting theory over practicality.<\/p>\n With that failing grade, the professor has sent the wrong message to his students: that results are not as important as being true to the theory. And people wonder why so many Java projects fail…<\/p>\n Why theory over practicality is total bull: <\/strong><\/p>\n I think the first point is self evident, so let’s look at the 2nd point and consider one of the fundamental theories of modern software development: inheritance.<\/p>\n At one time in the distant past (5 years ago,) design-by-inheritance was the theoritically correct method of software development. At some point though, people began to discover that inheritance had its’ problems and now (in many cases,) design-by-interface* is the preferred method. <\/p>\n Theories change <\/strong><\/p>\n The shift from design-by-inheritance to design-by-interfaces is but one example of how theories are constantly updated to reflect practical realities. <\/p>\n If anything is consistent of about software development, it’s that theories change. So don’t sacrifice practical application today, to satisfy some theoretical construct that may very well be discredited tomorrow.<\/p>\n –<\/p>\n Stefan Mischook<\/p>\n 1. ‘bull’ is a technical term that conveys a complex meaning in a terse and well understood format.
