It wouldn't be right to have a web site, be a nerd, and not take this opportunity for a bit of shameless pluggery.
If you like all these weird and magic internet page things, you should try Coaster Nerd, Oxford Bloggers or, if you'd really like some unexplainable sourcery, is it the weekend yet.
Also you should follow me on Twitter ;)
I can be found fairly regularly at Oxford Geek Nights, OxTuttle and other general nerding out activities in and around Oxford.
I am also often found in my natural habitat which is anywhere that you can find an adreneline machine. I frequent English theme parks more often than is healthy, and take trips abroad to sample foreign rides.
Was having a decidedly crap day of development. Just got much better. It's nice when things go your way. #win 1 day ago
These posts were written at the time of writing and may not still be accurate or reflect my opinions any more. In fact, they may not even be correct or representative at the time of writing. You see, when I write, I just write. I don't do that thing which they always told you to do at school and plan what you want to write first. Because of this, there will almost certainly be a load of typos, grammar errors and incorrect facts and references. If this makes you feel queasy, I apologise that you had to get to the bottom of the page to read this, and hope that some day, you'll learn to forgive me.
Slightlymore started off all too formally for my liking. In the depths of the archives, you'll find tutorials. However if you read the more recent posts, you'll find them a lot more playful and about fun and interesting stuff.
