Go Time: Golang, Software Engineering episodes

October 14, 2021eBPF and Go
eBPF (7 years old) is a sandbox that can run code inside the linux kernel. It started as a technology to build firewalls, and has evolved over time to include a range of new features.
The panel discuss the origins of eBPF and how it works, as well as dig into some real-world use cases. While eBPF programs themselves aren’t written in Go (more like C), we will hear about how you can communicate with eBPF programs from your Go code.

September 23, 2021The little known team that keeps Go going
Ever wonder how new features get added to the go command? Or where tools like gopls come from? Well, there’s an open team that handles just those things.
Just like the programming language itself, many of the tools that Go engineers use everyday are discussed and developed in the open. In this episode we’ll talk about this team, how it started, where it’s going, and how you can get involved.

September 09, 2021Building actually maintainable software
Building software is difficult and time consuming, but the maintenance of software is where we spend the majority of our time. In this episode, Ian and sam join Johnny and Kris to discuss how to build actually maintainable software, the features of Go that make it good for writing maintainable software, and different ways that we might define the term “maintenance”.

To build or to buy, that’s a constant question we ask ourselves as software engineers. In this episode we dig into the nuance of these options and the space between them with an eye toward both the building of software and its eventual maintenance.
