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.

The trouble with databases

Databases are tricky, especially at scale. In this episode Mat, Jaana, and Jon discuss different types of databases, the pros and cons of each, along with the many ways developers can have issues with databases. They also explore questions like, “Why are serial IDs problematic?” and “What alternatives are there if we aren’t using serial IDs?” while at it.

Stop the presses

Newsletters play a unique role for developers. As the Go community continues to grow and mature, these newsletters provide a much-needed filter for the oft overwhelming stream of new articles, talks, and libraries produced by the community on a weekly basis.

In this episode Johnny, Jon, and Mat are joined by Peter Cooper of the Golang Weekly newsletter to discuss his role as a newsletter curator. We explore difficult topics that touch on ethics and responsibilities of a curator and of course, the impact Peter and his team have on shaping, at least in part, what many in the Go community get exposed to.

Quack like a wha-?

Interfaces are everywhere in Go. The basic error type is an interface, writing with the fmt package means you are probably using an interface, and there are countless other instances where they pop up. In this episode Mark, Mat, Johnny, and Jon discuss interfaces at length, exploring what they are, how they are using them in their own projects, as well as tips for how you can leverage them in your own code.

Unusual uses for Go: GUIs

Johnny and Jon are joined by Andy Williams to talk about some of the unusual ways developers are using Go. In this particular episode they deep dive into building GUIs and discuss all of the challenges imposed by trying to build a UI that is both cross platform and functional. How do you create buttons that work on both mobile and a desktop app? Should you even be designing both apps at the same time? Tune in to find out!

Code editors and language servers

In this episode we talk with Ramya Rao about code editors and language servers. We share our thoughts on which editor we use, why we use it, and why we’d switch. We also discuss what a language server is and why it matters in connecting editors and the languages they support. We also dive into various ways to be effective with VS Code including shortcuts, plugins, and more.

Why can't we settle on a single application structure in Go?

Go Time panelist Jon Calhoun ruminates on a conversation started on episode 94 of the show:

The goal of this article is it explore why exactly there isn’t a single app structure that is recommended to new Gophers, and the overall goal of this series is help newcomers to Go understand what choices are available to them so they can get started a little easier.
