Welcome to my website, which fills some gaps in cyberspace with information about my career as a technical author and pages about my hobbies.

These include

• Computer programming, mainly in Python
• My family history
• Historical linguistics
• The Voynich manuscript (I was one of a select group who said it was 15th century before the carbon dating)
• Geology
• Scientific heresy

This home page will contain personal stuff such as

• My trip to the Voynich centenary conference at Frascati
• My visit to the Balcombe fracking protest
• Pet theories about things like the geology of the Wealden Basin
• The inventory of my ancestor Richard Sibbering, cordwainer, 1738. Not all my ancestors were poor.

This website was started in April 2015 and upgraded in July 2016. I have still not set up email but you can reach me at
