Over the years I have worked with many different programming languages, platforms and technologies.
Some have faded out as nothing but nostalgic memories - like QBasic, Pascal and Delphi and Perl. Some are still very much used - but not so much by me any more - like Java, PHP and MySQL.
And then there are all the technologies that still fascinate me. Here is a list of some of them - co-incidentally the same list that I tag my blogs with.
I don't claim to be an expert in all of these fields - many of them are complicated enough that people spend lifetimes mastering just one.
But I do have both interest and experience in all of them.
