We're having a bit of fun with Facebook today and its apparent inability to correctly locate users. It's pretty common if you update your status in Birmingham to find it labelled as coming from Chaddesley Corbett a lovely village in Worcestershire about 16 miles away.

It's a problem experienced by viewers on our too. You told us that the website often puts you anything between 20 and 187 miles away from their true location.

So why does it happen? Well anything connected to the internet has anwhich as you might expect allows other computers to work out where it is, at least in cyberspace. Trouble is using an IP address for a physical location may lead you to the sort of problems Facebook is experiencing.

When I post from Facebook at work (in my break obviously) then I'm often tagged in Bloomsbury in London. And by using an online tool like you can see that's where my work computer has it's IP address. Some Ö÷²¥´óÐã server in London. Makes sense in cyberspace, produces a bit of a disconnect in the real world.

Facebook told us;

"Facebook's mobile app uses positioning data provided by the phone's operating system. This is compared to a database of place names. Occasionally, inaccurate results will be returned. We are constantly working to refine the technology."

And given our apparent insatiable desire to tell Facebook everything about us sooner or later things will certainly improve. Which of course will allow Facebook to target us with ads even more effectively.

Which just leaves one puzzle. I can understand how an IP address in Birmingham leads to a server in London. What I really don't understand is why Birmingham sometimes becomes Chaddesley Corbett? Is there some massive server farm or internet node I don't know about in the sleep Worcestershire village? If you know more hit me up in the comments.

So today I've been filming at the University of Birmingham where they've been simulating treetops and monkeys. Using experts in parkour or "free running" to pretend to be orangutans who then have to navigate the university gym while wearing scientific equipment.

Turns out real apes don't like wearing masks and computers to monitor their CO2 and oxygen levels and hence energy used swinging through the trees. But Brendon from EMP Parkour is happy to oblige and also to mimic monkey movement. Turns out he tries to copy what gibbons do for some moves anyway.

In the past researchers have used rock climbers for this sort of study, but the movement of parkour is a closer fit to how apes really behave.

The aim is to understand how the behaviour of orangutans is shaped by the energy needed for some movement which is in turn shaped by the environment and available food. It might also reveal something about how our evolutionary ancestors moved as well.

It was certainly an entertaining morning and there's some great footage from the minicam Brendon wore on his head during one run. Watch it here.
