Go on Fuchsia OS

Fuchsia is the new OS from Google based on a new non Linux kernel that could replace Android. Few Programming Languages will be supported and Go is of course one of them. This talk will highlight how to write an application in Go for Fuchsia and will also serve as an introduction to the new OS.

Goroutines: the dark side of the runtime

Have you ever wondered what really lies behind the “go” statement? Did you ever stop and think about differences between goroutines and standard operative system threads? Is there something you should know to avoid bugs or weird, unintended behaviours?

Decoding invalid base64 with state machines

How many times did you try to decode a string and couldn’t because it was malformed? With state machines, we can dynamically decode malformed or incomplete strings. This talk will discuss how to implement such state machines and the problems you might encounter.

Project layout patterns in Go

You completed the tour, learned the language, got your pet project on Github. Time to start a new project, a big one: how do you organize code, tests, docs? During the talk I’ll try to save you some trial and error by sharing the lessons learned during a year spent coding a non trivial Go project.

Gomacro: code generation made easy and fun

Go code generation was traditionally still a difficult topic. Armed with Gomacro REPL, we will see how creating and manipulating abstract syntax trees (go/ast.Node) becomes as easy as adding few keystrokes to a statement or declaration. And you can do it interactively: much more fun and productive.

Fast messaging with Nats and Go

Even if synchronous calls are the most popular way to communicate between distributed services, event based communication is a common alternative due to its advantages in terms of decoupling between producers and consumers.

Debug like a pro on Kubernetes

Go fit perfectly inside containers, you can ship apps as tiny images on k8s, distributing them across the globe. Gianluca will show how InfluxData debugs containers running on Kubernetes to allow sysadmins and developers to troubleshoot and replicate issues using core dump, debuggers, and logs.

Unit Testing Code with Hard-To-Mock Dependencies

Unit testing using mocks is a common technique in Go and other languages. However, some dependencies are harder to mock than others; standard library packages such os can be particularly tricky. This talk covers strategies for effectively testing code that depends on such hard-to-mock packages.

Building great APIs with gRPC

It generally takes lots of time and decisions to create an HTTP API, but when you want to get productive fast, you want to skip as many steps as possible. I’ve been working with gRPC for almost a year and I can guide you from first lines of the code up to request tracking or exposing it via HTTP.

Cgo for fun and profit (read pain and suffering)

Famous last words: “CGo will allow me to write code in Go once and invoke it from other languages easily”. I demonstrate that this approach is mostly more trouble than it’s worth; by doing a live end-to-end exercise of invoking go built shared library from other higher level languages.
