What's new: (2013)a macro-processor for web pages at Source Forge

and a mashup music video to support keeping easy access through Sheffield station.

2013 - coming soon - how to write a compiler.

I am now retired (2009) from the School of Computing and Management Sciences, at Sheffield Hallam University.
Currently, my main technical interests are programming languages (Java, VB.net), scripting, software engineering, and the Internet. (see below for a sample chapter from ‘Java for Students’.)
Outside computing, I'm doing music, yoga, reading American crime novels, and writing books.

Technology used to write the books prior to 2007:

The Amstrad nc200 - great keyboard, runs off torch batteries, has a floppy disc. £40 on Ebay.
OK - it has CP/M OS, and can't do graphics or run Word. I work in HTML, and have written stuff to insert code extracts. Also, it doesn't use a mouse, and this was good for me, to avoid RSI. Some old technology is good!
