I wrote this simple piece of code to validate ISBN strings and I publish it because I hope it can be useful for someone else.

I know, I’m probably too old for school but this is not a real one: it’s an online class!

But let’s start from the beginning!

Few weeks ago my colleague Jay tweeted me about the existence of this online class about how to develop websites/web apps for mobile devices.

So which better moment than this to go back and study again?

I have a lot of expectations from this class because I always wanted to learn about web and mobile devices and I never had time to spend on this!

The class is going to start next week and I already have something to read!

I’ll keep you updated!
