The number one indicator of success I've found is a willingness to commit to a lifetime of learning. A degree is one means of learning, but there are others. Either way, learning doesn't stop after a degree -- it has only just begun.

A major reason I began prototyping Pulumi was that I fell in love with Docker during the .NET cross-platform and open source projects.

If even half of this gets done, Swift will have a supremely badass generics type system (technical term):
