Welcome to the Picalo site! Picalo is a data analysis application, with a specific focus on fraud detection. Since the beginning, I released Picalo as open source software, and it is still available. I stopped development on it in 2010, although I may come back to it at some point.
I suspended development because I've been busy on a startup company, MyEducator. After many years of charging my students $200+ for textbooks, I finally gave up hope that the big publishers would bring down costs and come to the modern web. At MyEducator, our textbooks are really courseware: they include video, animations, text, embedded and adaptive problem sets, etc. Our courseware looks like a regular web site and is programmed in regular HTML5. No encryption, no DRM, no Flash boxes. Yet our model still protects authors and is based on a solid revenue model (I won't go into it all here -- just know that I really believe we have a chance to change things).
Most importantly, we are able to set a much lower price point than traditional publishers because we've cut out all the bureaucracy and unneeded layers. My hope is that the effort will be able to make a big difference in higher education with this company. We're going to change the way students buy and learn from textbooks.
I may or may not come back to Picalo. I'm still a strong believer in its model of data analysis. I would love to see continued development. It all depends on how the startup progresses.
You can continue to download copies of Picalo here. Look for the latest version numbers.
Thanks for all your support over the years; I hope to see continued development in the future.
Best regards, Conan Albrecht
