Hi, my name is Wayne Ashley Berry

I have been writing code professionally for 11 years — the past 4 years working on Over as a backend engineer. Last year we were acquired by GoDaddy and I have since been promoted to Principal Software Engineer. Previously, I co-founded Next and functioned as the Lead Developer & CTO for 6 years.

You can reach me on Twitter or LinkedIn. I have some old work up on Dribbble as well.

I love Firebase and I recommend you give it a go! This is just an important learning that I wanted to share — hopefully it can prevent you from getting stuck in the same position as me.

The Most Exciting Feature of Go 1.8

You might think that the built-in support for gracefully shutting down http servers is reason enough to be excited for the upcoming Go 1.8. It could also be the proposed sub-millisecond GC pauses. Heck, if you’re having refactoring issues on a Google scale then it could be the controversial addition of alias declarations. Based on my experience, working with small teams and people new to Go, Go 1.8 shipping with a default GOPATH is going to be the most groundbreaking of all new features.
