I live in England. I am a native English speaker, and retain some schoolboy French. I have a science degree.

I can program in Prolog, Perl, and PHP, and write raw html.

I like maps.

I have an account on Wikimedia Commons.

Interactive maps[edit]

Interactive maps are a new tool being developed by the Wikimedia Foundation – see Maps/Conversation and mapbox gallery. They rely on Template:Mapframe, which is already running here on en:Wikipedia, and on some javascript, which is not. To get the javascript working, I copied it from here to User:Maproom/common.js. You can get it working for you by doing the same, using your own username. Once you have done that, you will be able to look at the specimens in this test page.

Cayley graphs[edit]

The Möbius–Kantor graph, the Cayley graph of the Pauli group

I have added two Cayley graphs to articles. You can see one to the right, and at Pauli group. If you think it would be useful to have more such Cayley graphs of small groups in articles, please let me know, and I will provide them.

Help Desk and Teahouse[edit]

I am active at the Help Desk and the Teahouse. I try to give accurate answers to the questions there, rather than to give reassurance to those asking them. Here are two of my responses, chosen not because they reflect well on me (they don't), but because they amuse me: chemical conditioning, Mustafizur_Rahman.

Thanks for edits[edit]

Maybe you have come here because I thanked you for an edit, and you are wondering what motivated me. I have certainly wondered what has motivated some of the thanks that I have received.

If I have thanked you for reverting an edit I made, it was to acknowledge that you were right to do so. Otherwise, it might be because I saw your edit, and thought "that is a conspicuously good contribution to Wikipedia." Or maybe your edit made me think "I wish I had said that." Or even both.

T. officinale

This is here to remind me how to use "crop" within a gallery.

The Right to be Forgotten[edit]

These English Wikipedia articles

and these Commons images


are the subjects of removal notices from the European Union to Google under "Right to be forgotten" legislation, as listed here. (That source also lists other items which are not mentioned above, because they have been removed from Wikipedia, to comply with other saner laws.)

Animated gif[edit]


I find this image quite disconcerting, as it appears to rotate one way for several turns and then, for no reason, start rotating the other way.
