I have been asked to give a talk at tonight’s “Code Ninja” workshop. Code Ninja is a competition for Galway students involving mobile or web apps/games. So Shiva’s just perfect..
Anyway, here’s my presentation slides (pdf, 1MB).. I hope they’re useful to someone 
The talk is only 45 mins long, so there’s no way I’ll get everything covered that I want to, but I figured I might as well make a more complete presentation so it can be useful to people after the event too. I’ll likely have to skim over bits of it.
