Workshops
Web Services in Go
Bill Kennedy
Summary
The Ultimate Service is a class for any Go developer who wishes to learn how to build production ready and well tested web services in Go. This class provides an intensive, comprehensive and idiomatic view of building web services using community accepted idioms and practices.
Details
The class goes beyond just the use of the http package and focuses on building CRUD based services with logging, observability and debugging. We believe this class is perfect for anyone wishing to build production ready, scalable, fast, and highly concurrent web services in Go.
Start/Stop
Logging/Configuration
Web Framework Design
Database Support
Testing Support with Docker
Metrics/Tracing
Prerequisites
Having a background in software development. Experience writing services in any other language is a bonus.
What a student is expected to learn
Everyone is going to be mentally exhausted by the end of the day. We will be challenging every student to think about what they are doing and why. If you want to be a better Go developer, code reviewer, designer and architect, this is the class you want to take.

Introduction to gRPC
Tim Raymond
Summary
Building distributed systems can be extremely complex, but it doesn’t have to be. gRPC was created as a high performance RPC framework that makes it easy for to build client/server applications. Using protocol buffers, you can define both data messages and procedure calls that turn into easy to consume structures and services in Go.
What a student is expected to learn
Students will learn how to define Protocol Buffers, as well as how to properly modify them for future revisions to be backwards compatible. They will also learn how to define and consume simple requests via RPC (known as unary calls), as well as more advanced client, server, and bi-directional streaming services. Finally, the students will learn how to create the boilerplate client and server applications, as well as how to create middleware, secure their services, and if time permits, to monitor and track their rpc calls across their distributed application structure.
Prerequisites
A basic understanding of the Go programming language. Beginners are highly encouraged to attend this training. While not necessary, it will be helpful if you have completed the Go tour (https://tour.golang.org).

An Introduction To Functional Programming In Go
Eleanor McHugh
Summary
Every coder thinks they know functions. Neat little packages of code for hiding away all that ugly implementation detail we only want to write once and would prefer no one else ever saw. In fact we take them so much for granted that when academics wax lyrical about their amazing potential we tend to assume they’re talking about the very same thing and wonder what all the fuss is about. Especially when presented with languages like Haskell which read more like a maths textbook and come with that knowing smile our parents had when telling us to eat our green vegetables: this is better for you.
They’re essentially saying our functions aren’t proper functions. That we’ve embellished them with junk we don’t need and that by using a pure functional language we’ll build healthier programs.
But what if I were to tell you that for all it’s practical engineering bias Go has a pretty robust concept of what a function is and how it can be used that means we can steal insights from the academic world? That we can choose to be functional programmers when we want to and - heresy of heresies - use other paradigms when they make more sense to us?
Join me in a relaxed workshop setting to explore functions in Go both as a mathematical abstraction and useful little machines for getting stuff done. There'll be a couple of simple problems to illustrate the ideas we’ll be covering, plenty of code you can study later, and a few thought-provoking examples which may permanently change the way you think about Go and about coding.
