Godel Escher Bach QR Code shadow cube

The shadow of this cube in different directions gives QR codes pointing to the Wikipedia articles for Kurt Godel, M.C. Escher, and J.S. Bach respectively. Also a pretty challenging print test. Note that QR codes cannot be read in mirror image, so only 3 of the 6 possible cube orientations cast a readable shadow.

Gotchas, Irritants and Warts in Go Web Development

Working in Go was tons of fun; the language designers have put a lot of work into making the language a joy to use. We particularly appreciated the first-class focus the language puts on the parts of development that are uninteresting in theory but very important in practice, such as third-party library management, coding convention enforcement, and testing.

I’ve been enjoying learning Go and developing some prototype web apps in it. It’s a new language and while it still has some bumpy areas, it’s great right now and you can have a lot of fun developing in it. It’ll be interesting watching it mature over time.
