I have a degree in Computer Science and Mathematics from London University, worked for over 20 years as a senior IT technician and team leader, much of that time for dealing rooms of international banks. I became a full-time, professional book indexer in 2004 and retired on Jan 1st 2015.
I also created the software WordEmbed, used by professional indexers, which I include on this site along with some supporting notes.
I also re-publish here some articles from my previous blog which some people have found helpful.
I hope you will find things here to make your life with computers easier and more productive.
