Four short links: 22 July 2009
Augmented Reality, A/B Psych, Open Source Heartbeat, Launchpad Launches
- ARtisan — AR Flash library, the fastest and easiest way from point A to point B in browser based augmented reality. Love the demos on the home page. (via and bjepson)
- How to Increase Sign-ups By 200% — A/B testing from 37Signals showed that “See Plans and Pricing” got twice the clickthroughs of “Free Trial!” and variations thereon. (via kathysierra on Twitter)
- Open Source Heart Monitor, Possible Blood Sugar Level Detector — another step forward in sensor networks and personal data: I’ve set up a quick prototype of a device that will monitor my heart rate while I sleep. It includes a BUGbase + BUGvonHippel module (from my company Bug Labs). I’m also using a custom module we put together that uses a Polar radio receiver (from Sparkfun) and a Polar strap that I wear around my chest. Lastly, we wrote a simple program that runs on the BUG to log the data. (via chr1a on Twitter)
- Launchpad Opensourced — Canonical’s code hosting and collaboration platform that was heavily lusted after in the open souce world, finally open sourced and in its entirety. GNU Affero license.
