Jon Calhoun

Jon started programming at an early age (around 8-9) when introduced to Apple Basic. Since then he has been hooked, learning about web development, scripting levels in videos games, algorithm competitions, and more. He eventually discovered Go and loved the language, but felt the resources for newcomers was lacking which lead to him starting to create videos, tutorials, and other educational resources. Some of his more popular courses include Gophercises, a course composed of mini coding exercises each designed to teach something unique aspects of Go, and Web Development with Go, an in depth course that teaches how to build production grade web applications from the ground up in Go.

SIV and the V2+ issue

Go modules brought about quite a few changes to the Go ecosystem. One of those changes is semantic import versioning (SIV), which has a fairly pronounced effect on how libraries are identified. In this episode we are joined by Tim Heckman and Peter Bourgon to discuss some of the downsides to these changes and how it has lead to what a subset of the Go community refers to as the “v2+ problem.”
