The Shape of Alpha – using mass data to reveal the perceived shape of geography [Code: Flickr Developer Blog]
“Plotted all the geotagged photos associated with a particular ‘Where On Earth ID’ (a database of places and bounding boxes, which describes the spatial hierarchy between places) to generate a mostly accurate contour of that place. Not a perfect representation, perhaps, but something more fine-grained than a bounding box.” How cool is that!?

Neighbourhood Boundaries [tomtaylor.co.uk]
Using the Flickr shapefiles to show you where the world thinks its neighbours are. Tom has written a bit about it here: “Of course, it’s not always right, so Flickr give you the option to override the place they guessed, with a more accurate name, as you perceive. For example, a photo taken near South Bank might better be described as Waterloo, or Embankment. Over time, this database leads to a more accurate representation of the shape and boundaries of the places in question, comprised of thousands of people photographs. Flickr are good enough to release this data in the form of shapefiles.”

The First 100 Days – what past US Presidents did in their first 100 days [goodmagazine.com]
Interesting to see how the first 100 days appear to be a good indicator for the tone and direction of the rest of the presidency. I now know what all Presidents and PMs should be made to answer “what will you do in your first 100 days”.

How to Price Your iPhone App out of Existence [Safe from the Losing Fight]
There will be an iPhone app bust. The current prices simply aren’t sustainable. Either developers will crash out of the market when they discover they can’t make a living off their current prices, or the gold rush developers will lose interest and leave when they realize they can’t make a quick buck off the store. The developers left standing will be the ones who set reasonable prices for their applications.

Wise words from Nick – who continues the good fight in the war to kill of the UGC term. It is such a rude and self limiting term.

Life in the Linked Data Cloud – Calais Release 4 Coming Jan 09 [OpenCalais]
OpenCalais is to release its data as RDF and join it to the LOD cloud.

The mobile computing cloud needs OAuth

As Paul Miller notes Cloud Computing is everywhere – we are pushing more and more data and services into the cloud. Particularly when accessed from mobile devices this creates an incredibly powerful and useful user experience. I love it. The way that I can access all sorts of services from my iPhone means that an already wonderful appliance becomes way more powerful. But not all is well in the land of mobile-cloud computing; a nasty anti-pattern is developing. Thankfully there is a solution and it’s OAuth.

So what’s the problem then? Since Apple opened up the iPhone to third party developers we have seen a heap of applications that connect you to your online services – there are apps that let you upload photos to Flickr, post to Twitter, see what’s going on in Facebook land all sorts of stuff. The problem is the way some of them are gaining access to these services by making you enter your credentials in the applications rather than seeking to authorise the application from the service.

Probably the best way to explain what I mean is to look at how it should work. The Pownce app is an example of doing it right as is Mobile Foto – these applications rely on OAuth. This is how it works: rather than entering your user-name and password in the application you are sent over to Safari to log into the website and from there you authorise (via OAuth) the application to do its thing.

This might not sound so great – you could argue that the user experience would be better if you were kept within the application. But that would mean that your login credentials would need to be stored on your ‘phone, and that means that you need to disclose those credentials to a third party (the folks that wrote the app).

By using OAuth you log into Flickr, Pownce etc. and from there authorise the application to user the site – your credentials are kept safe and if your iPhone gets stolen you can visit the site and disable access. Everything is where it should be and that means your login details are safe.

To be fair to the iPhone app developers this type of delegated authorisation isn’t always possible. Twitter, for example, still hasn’t implement OAuth and as a result if you want to use one of the growing number of iPhone Twitter app you need to give up your user-name and password. I find this incredible frustrating – especially from a service like Twitter where (according to Biz Stone, Twitter’s co-founder) “the API… has easily 10 times more traffic than the website“.
