Welcome to Duncan White's Practical Software Development (PSD) Pages.

I'm Duncan White, an experienced and professional programmer, and have been programming for well over 30 years, mainly in C and Perl, although I know many other languages. In that time, despite my best intentions:-), I just can't help learning a thing or two about the practical matters of designing, programming, testing, debugging, running projects etc. Back in 2007, I thought I'd start writing an occasional series of articles, book reviews, more general thoughts etc, all focussing on software development without all the guff.
