Workshops
Profiling and Tracing Go Applications
Bill Kennedy with Ian Juma
When
May 26th: 15:00-21:00 Central European Time
Summary
This class teaches how to use the profile and trace tooling in Go. We will use practical programs to find performance problems and based on what we find, refactor code to gain better performance.
Language Mechanics / Semantics
Memory (Stacks / Heap) Tooling
Program Tracing
Micro-optimizations
Profiling Running Applications
Prerequisites
A basic understanding of the Go programming language. Students do not have to be expert Go users but they will get the most from the workshop if they have completed the majority of the Tour of Go.

PRACTICAL GO: The Skills You’ll Need to Work with Go
Johnny Boursiquot and Kevin Siende
When
May 26th: 15:00-19:00 Central European Time
Summary
This workshop helps developers get up to speed with Go from the ground up, covering basic language syntax through to concurrency. Along the way, you learn best practices for project layout, testing, reusability, and dependency management. You get practical, hands-on experience tailoring your development environment for Go development, building CLI tools, writing HTTP servers, and developing concurrent programs with goroutines and channels. The aim of this course is to build your confidence in starting new projects in Go.
Prerequisites
This workshop is aimed at developers with some level of experience with other languages and/or with some exposure to Go. We'll assume you are already familiar with basic programming concepts like conditionals, looping, arrays, maps, etc. and we won't spend a lot of time explaining.
You are also expected to know how to:
- Work with a shell environment (bash, Windows PowerShell, cmd.exe, etc)
- Work your way around your file system (cd, ls, mkdir, mv, etc)
- Work with environment variables
- If you are completely new to Go - as in "I've never even seen the syntax or written a 'Hello World' program" - you can get a feel for the syntax with the following resources:
- The Go Tour
- Go by example
You will also need to install the following:
- Git
- Go (1.13 or higher)
- Visual Studio Code (highly recommended) or an editor with support for Go syntax
What a student is exepected to learn
The following are the topics covered in this course:
- Language Basics
- Syntax and Types
- Packages
- Arrays and Iteration
- Slices
- Maps
- Pointers
- Functions
- Errors
- Structs
- Interfaces
- Command Line Tools
- Testing
- Interfaces
- HTTP Servers
- Dependencies
- Concurrency Basics
- Goroutines
- Channels

Application Security
Anna-Katharina Wickert
When
May 26th: 15:00-19:00 Central European Time
Summary
This workshop is for all gophers who not only want to build cool applications and also want to include security into them. Application security is a complex topic and can be hard to get into Thus, we will go the first steps with you into the rabbit hole of (Go) security.
Together, we start from a very simple web application, learn basic security concepts, and especially how to harden our application in an easy way against those attacks.
To achieve this aim, we’ll explain shortly to you an attack to provide you with the necessary information to conduct the attack. After you have seen by yourself that your application is vulnerable, we will together fix this issue and move forward.
By the end of the workshop, you will have a simple web application that is protected against basic web security attacks, like CSRF, avoid (at least one) memory safety vulnerability, and supply chain attacks.
Prerequisites
- Each student should have a basic understanding of the programming language Go and software development.
- We highly encourage Go beginners to attend this training and recommend at least the completion of the Tour of Go.
- Experience with security is a bonus and not required.
- The philosophy of our workshop is to understand new things by doing, and especially by “breaking” their solution before improving it. Thus, we expect a student to be okay
- with critically reflecting on their solution and failing.
What a student is exepected to learn
- Students will learn to harden a simple (web) application in Go against basic web security attacks, e.g., CSRF, circumvent the memory safety of Go, and pin their dependencies to avoid supply chain attacks.
- During the workshop, we will challenge every student to reflect on their code and understand the diversity and complexity of security.
- After the workshop, every student will be able to dig into the rabbit hole of (go) security a bit more and check their application against the presented attack vectors.
- A student of this workshop will not attend a security competition, like capture the flag, nor will a student have a theoretical or an in-depth/advanced introduction to any of the covered topics.
