Clive's Page

Clive's UndergrounD Line Guides - a line-by-line guide to the features and history of London's Underground. As well as being the oldest such system in the world, the Underground remains one of the largest and most complex.

More railway material, including links to other sites. This isn't a trainspotters' site. My main interests are in signalling and safety, and this bias is reflected in the contents of the pages.

Information about the Psion Series 3, 3a, and 3c pocket computers, including The Psionics Files, which provide detailed information for those wanting to do more programming than the OPL manual explains.

C - the language and the Standard. I am currently a member of the UK panel on C, and taking an active part in the development of the new C Standard ("C9X"). To this end, I have made a number of proposals and written a number of other papers.

Telephones - information about telephones, telephone numbers, and call charging.

Presentations that I have given.

Notes from a meeting at the Home Office on 1996-01-19 to discuss the issues of regulating "adult material" on the Internet. While the meeting itself reached little or no conclusions, it was the start of quite a lot of activity culminating in the formation of the Internet Watch Foundation.

Legal issues, such as the interception of email.

The Romans and some oddities about them, such as a catalogue of the legions.

Science and Mathematics; a collection of random articles about things.

My gallery of photos, provided off-site courtesy of Joel Rowbottom's Fotopic site.

Miscellanea that don't deserve their own headings. For example, there is a description of the rules for Easter, where they came from, and how to calculate the correct date.

My useful or interesting links; this page starts with a set of pointers into the main document. I also have a collection of older links. Many of these are probably no longer available; as I get time, they're being merged into the proper links page. I also have two other web sites:  STDC and  On The Train.
