I am an I.T. person and a RPGer - currently dealing with Mongoose Publishing's Traveller.
My Information Technology page has some articles that I have written over the years. It also has a snapshot of my current skills.
I have some pages about Free Software with some dedicated pages - one for Linux and one for Windows.. I use Linux so I'm pretty much OK for free software. Also on the main Free Software page I mention special disc images to be used when something has gone terribly wrong - they're called "live CDs" which means you boot your computer with them.
My Sinclair QL page is there with some odds and ends left over from my QL days.
My Health page has some of my writings including "HOWTO - The Brain" and "Mental Health Presentation".
My first computer articles were written using Psion Quill on the Sinclair QL. Initially my scribbles on PCs were stored in Microsoft Word (.doc) format. After that I started using free office suites - initially OpenOffice and later LibreOffice, still saving stuff in Microsoft Word format. Then I started saving stuff in ".odt" format - both OpenOffice and LibreOffice can handle that format (and Microsoft Word format) - for free!! However, I have had a change of mind. Lots of devices these days support PDF straight away. Which is why I am now uploading stuff as PDF files
