I'll be leaving on vacations for a couple of weeks soon, so it's very unlikely that you'll see updates in that time frame here. Vacations are a good time to recharge batteries and spend time broadening horizons, which also helps connect dots sometimes... Read More...

Rich Visualizations with Silverlight and Astoria

How we get here I found myself wanting to have a nicer way of looking at a bunch of data I reference every now and then. Often I will whip up a quick HTML application to do this - it's ultimately a simple text file I can quickly edit and tweak, and the Read More...
