Just letting you know because as a Spanish speaker I've had the same problem. It's not "an smartphone" because it's not pronounced esmartphone, you've to start the word from the 's', sssssmartphone,so it's actually "a smartphone".
The title is a little misleading. Surely it should read Using only CoffeeScript, Titanium, Node, Socket.io and a Chrome extension...
In fact, the title has very little to do with the actual article (which to be fair uses the same misleading title). Should be "Building a Chrome To Mobile extension using JavaScript only".
It's a shame because the actual project looks cool, just wish some more details were included.
why is this even on the front page? Without context the presentation is pretty much useless.
If you are interested in app development with coffeescript just search github for titanium + coffeescript and you'll get lots of cool templates and examples.
