And programmers, as I quote Larry Constantine in my book, programmers are programmers because they like to code -- given a choice between learning someone else's code and just sitting down and writing their own, they will always do the latter. And the programmer who says, it will be faster for me to write it, rather than to learn it, is usually correct. Except that what he will write, most likely, is something that will work but will not have its rough edges worked out, will not have the benefits of a piece of software that has actually been used for a few years, where the bugs have been found and the users have given feedback and have helped you figure out where the problems are. So what they will often be handing you at the end of that I-can-do-it-faster-myself thing is something that works, but that is kind of a mess in certain ways. Whereas the thing that you were going to pull off the shelf, maybe it will take the programmers a while to learn it, but once they learn it enough to hook it up to this project you are creating, what they are hooking up will probably have a lot fewer problems.
