Schedule

We've been working tirelessly for months to bring the best and brightest minds in the industry to GoLab. 

This year, we're thrilled to introduce an exciting addition to our conference: the Geek track!

The Geek track is all about bringing together developers from the Go and Rust communities to explore topics that interest both attendees. It's a unique opportunity to discover the synergies between these powerful languages and share experiences, insights, and best practices.
In the Geek track, you can expect Rust talks, Go talks, Rust and Go talks, as well as talks that cover other interesting topics!

So whether you're a long-time Gopher, a newbie Rustacean, or anything in between, please join us for this fascinating experiment where inspiration, learning, and the joy of programming come together.
See you there!

Ultimate Service with Kubernetes

This class teaches how to build production-level services in Go with a focus on macro-level engineering decisions. From the beginning you will program along with the instructor, walking through the design philosophies and guidelines used to engineer the code. With each new feature, you will learn more about the transition from programming to engineering and the points of refactoring required to write production-level applications. Throughout the class, Go modules and Kubernetes will be a focus. Everyone will be making better engineering decisions after this class.

NOTE: according to the instructor, there will be two coffee breaks; one in the morning (about 11:00) and one in the afternoon(about 16:30) plus the lunch break (13:00).

Modern Cloud Development with Service Weaver

This class teaches how to build distributed applications in Go with Service Weaver. At the beginning of the class, the instructor will walk you through the motivation behind Service Weaver and introduce you to the core abstractions that you need to know in order to develop a Service Weaver application. In the second part of the class, we will develop, instrument, test, and debug an emoji search engine application that will run in the cloud.

Keynote: State of the Go Nation

Go has come a long way in recent years, with a more productive, coherent experience than ever before.

In this talk, we'll review the latest advancements in the Go language and toolchain, and how the Go Team leverages its portfolio of projects to create complete, developer-centric solutions.

Go<<CUE: Shifting Go left with CUE

Where does your Go run? How do you tell it what to do?
Configuration is a huge part of modern development but while we benefit from Go's static type system to catch programming errors early, we don't have the same for configuration data. This talk explains how the new CUE language integrates with Go, "shifting left" your Go types to earlier stages of deployment, reducing risk while bringing joy.

How Go taught me to love building apps again

Building apps is tough and involves lots of languages to reach multiple platforms - unless you build them with Go and let the tools do the hard work!

Understanding the successes and pain points of different testing strategies

Do you enjoy testing? Some say yes, some say no, but for most I believe the most ‘senior’ answer is ‘it depends’.

So, what are the variables that determine this? Culture? Code? Something else beginning with C?  This is what I’ve spent the past few months investigating, so come join me and find out!

Towards modern development of cloud applications

We used Go to build a new cloud programming framework at Google. The way people use microservices to build distributed systems slowdown innovation and hinders application’s performance. Instead, the developer should split the code at logical boundaries and delegate execution challenges to a runtime.
