I recently updated my personal site (just a quick tidy up really) and I noticed I display where I am based but I am not always actually in that location. Thinking back to a recent update by IFTTT in which they announced a partnership with JetSetMe I started to think of a way I could show this information without having to actually update this myself.
I setup the JetSetMe channel in IFTTT. The JetSetMe service is something O2 are experimenting with which allows you to do things when O2 spot that you have arrived in a new country.
When JetSetMe picks up a new country IFTTT get triggered. I have IFTTT store data in JSON format in a file in Dropbox (you can see the recipe here). I then have a CRON job running on my server which opens this file periodically and saves all the data to a database which live.jamesmills.co.uk uses. This is basically how all the data on live.jamesmills.co.uk is generated.
I then have a very simple API on live.jamesmills.co.uk which gives me access to this data which means on jamesmills.co.uk I can show where I am currently located.
