I made a bunch of new moo stickers and moo cards for the <head> web conference yesterday (And So Can You!)
From the Simon Willison/Natalie Downe dream team comes yet another very useful service for Google App Engine developers: jsontime.
I have been meaning to blog about this for some time (no pun intended!)
EU-based businesses are required to obtain valid VAT numbers from VAT-registered entities.
Unfortunately, especially for e-commerce systems, there isn't a simple way to check the validity of a European VAT number. The European Commission provides a web site where you can validate VAT numbers by entering them in an HTML form. This is not practical, of course, for web applications.
Enter, the European VAT Number Validation API that I just hacked together on Google App Engine.
As I posted last week, a backwards-incompatible API change to the JSON version of Yahoo!'s excellent GeoPlanet API caused the new teaser site for the Singularity web conference to fail.
Today, I got an email from Eddie Babcock from the Y! Geo team informing me that this was due to a regression and that they will be issuing a fix today that will revert the API to its original state.
