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.
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.
