Almost fifteen years ago, I stumbled across the concept of version control in the form of RCS. I wasn’t real sure that this tool was going to be useful for me. After all, it required more work that did not contribute directly to producing code. In order to try it out, I began using RCS… Read More »
And just to prove that some ideas appear in many places all at once, Andy Lester explores naming again in O’Reilly Network: The world’s two worst variable names [Mar. 07, 2004]. Apparently, Lester is reviewing the second edition of Code Complete, one of my favorite books on programming, and says there is an entire chapter… Read More »
One of the fundamental laws of the universe could be called the Law of Unintended Consequences. This law is as universal as Murphy’s Law, but not as well recognized. To me, the gut-level understanding of this law is one of the things that shows the difference between a really good programmer and someone who just… Read More »
Isn’t it interesting how some ideas will surface in different unrelated places at close to the same time. O’Reilly Network: On the importance of names [Feb. 15, 2004] talks about how important the right name is for the success of a project. I think it may be more important not only for recognition but to… Read More »
What does it mean for an object to die? In C++, there are several distinct and well-defined stages in the death of an object. Other languages do this a little differently, but the general concepts remain the same. This is the basic chain of events for an item on the stack. Object becomes inaccessible Object… Read More »
I’ve been thinking more on the issue of Magic Constants. Have you ever noticed that when some people first understand the idea of symbolic constants, they want to collect all of the constants they’ve defined together in one spot?
A truly bad code example in a book on Java Servlets got me thinking about the idea of Magic Constants. Of course, we are all aware of the problem of magic numbers or magic literals in code. That’s why we use symbolic constants instead to hide that implementation detail (and to simplify maintenance later). However,… Read More »
perl.com: Maintaining Regular Expressions [Jan. 16, 2004] Aaron Mackey does a wonderful job of suggesting more maintainable regular expression idioms. His use of (?{}) to assign the results of capturing parenthesis inline was particularly interesting to me. I may have seen it before, but this is the first time it made sense. The article goes… Read More »
In attempting to do Test Driven Development, we noticed that one of the problems with testing object validation code was the necessity to have broken objects to test with. This is particularly important in cases where the internals of an object may come from somewhere uncontrolled. For instance, objects that may be read from disk… Read More »
