My talk ran longer than I'd have thought, and I hope it was interesting. Just for information I'm linking the slides and video here. Before you check the video I apologize for my voice. If I sound like I'm saying things like "you" where I should have said "you'd" that's my voice. It has nothing to do with the fine folks who did the recordings.
Here are the slides hosted at Slideshare.
If you have a Slideshare account you can download the PDF there. For those who without here's another link (via Dropbox).
Here's the video hosted in Refresh Colombo YouTube channel. My talk starts at about 06:50 into the video.
Next months Refresh is on 20 October. Drop by.
