A multi-coloured force-directed graph.

Force Directed Graphs of the London Underground have been done many times before – but I think I’m the first person to add the new Elizabeth Line (CrossRail). I’ve also created a JSON graph of all of London’s rail services – including DLR, Trams, C2C, ThamesLink etc. Demo Play with it yourself Grab the code…

When is an Electric Car not an Electric Car? When TfL say so!

by @edent | # # # | Read ~200 times.

Another middle-class rant about an easily solved problem. Or, how a software bug nearly cost me £80. Things you should know… London has a Congestion Zone. You have to pay £11 to drive through it. If you have an EV (Electric Vehicle), you don’t have to pay the Congestion Charge. Easy, right? Not quite. In…

A close up of the map.

One of my favourite works of art is The Great Bear by Simon Patterson. At first glance, it appears to be a normal London Tube map. But look closer… Cool! But there is something about it which has always bothered me. Each Tube line represents a theme – therefore, a station at the intersection of…

In a city of millions? Rubbish! This fails to address something that advertisers are conspicuously loathe to reveal…

I wander around the world in a perpetual state of confusion. Why is the world the way it is? Why do people make bad decisions? Why – when there are so many better alternatives – do people choose the worst of all possible worlds? Rather than getting bogged down in philosophy, I refer to the…

Sousveillance (pronounced /suːˈveɪləns/, French pronunciation: [suvɛjɑ̃s]) as well as inverse surveillance are terms coined by Steve Mann to describe the recording of an activity from the perspective of a participant in the activity,[1] typically by way of small portable or wearable recording devices that often stream continuous live video to the Internet.
