This class teaches how to build production-level services in Go with a focus on macro-level engineering decisions. From the beginning you will pair program 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.

In this session, Liam delves into the crucial topic of memory management, providing a comprehensive overview of what it is, why it matters, and how to harness its power to write highly performant and cost-efficient code. He navigates the intricacies of the Go memory model, highlighting its distinctions and similarities with other popular languages, whilst also explaining the use of built-in tools such as reserved keyword functions and pointers. Liam will also share valuable best practices and illustrate key concepts with both good and bad coding examples. The overall objective of this talk is to provide you with an understanding of whats under the hood and empower you to take control of your code and write more efficient and performant code from the start. |

Software development is more complex than ever, relying on a wide variety of libraries and third-party tools, in order to build solutions quickly. DevOps enables us to ship these changes faster than ever, but leaves us vulnerable to security flaws, as we have less time to find and fix dangerous issues. Therefore, in today's world, the only way that engineers can confidently write code is by embracing the shift left of security concerns.
By the end of the session, you will learn:

Ringbuffers are great assets for real-time large scale distributed applications. Ringbuffer integration is a replicated, but not partitioned, the data structure that stores its data in a ring-like structure. You can think of it as a circular array with a given capacity. Each ringbuffer has a tail and a head. The tail is where the items are added and the head is where the items are overwritten or expired. Each client is connected to a ringbuffer that can independently read items between the head and tail, which makes the ringbuffer an ideal candidate for publish and subscribe or efficient data replication use cases. This talk will discuss how you can level up Go applications using ring buffer structure. It will contain a demo hosted on Github.

It has been over two years since generics were introduced in Go. Have you done anything fun with it? I have! Ever since the "Creative Use of Generics Contest" at Gophercon 2021 I have been dreaming with a monads library implementation in Go. In this session I will walk you through the basics of generics, how I used it to build a monads library, the challenges, limitations and a comparison with non-generic Go. In the end, you will be the judge to the question: was it a good idea after all?

Are you a mid-level developer or an architect who’s curious about API Security and how to achieve it? In that case, we’re excited to help!! As you already know APIs are the building blocks of your application network. They are the medium of communication and participate in a lot of data transactions. As per Gartner’s report, API abuse will be the most frequent vector attack, and it’s quite evident. We have heard about API abuses and attacks quite often. To protect your APIs and provide complete security we will adopt the Zero Trust Security model. We will learn about the Zero trust model and its architecture. We will also understand how to implement Zero Trust Security in easy steps. By the end of the presentation, you’ll have a fair idea about API Security and how to protect your API ecosystems using Zero Trust Security. Come along with your queries for us! |

We use OpenTelemetry extensively at Torq. In fact we are tracing 100% of our traffic. We started building the product with the idea in mind that we dislike logs and want to use them as little as possible.
Since then we have grown to 30 engineers and everyone is in love with OpenTelemetry. We use it during development and to debug issues in production. We have automations built around it, special middleware we developed for our internal libraries to report traces (orm, pubsub etc).

Part of Go's brilliant developer experience is the integration of gopls with text editors like VS Code, Neovim to provide features.
Text editors use the Language Server Protocol standard to communicate. This standardisation allows multiple text editors to benefit from a single implementation.
In this session, we'll go deeper to find out what's being passed between text editors and the language server, how we can create our own LSPs with Go, and how a project is building on top of the gopls LSP to add autocomplete features to HTML templates.

It is generally seen as a scary thing to do: modifying the Go runtime. However, by creating a rolling fork, we can add functionality such as distributed tracing to regular Go applications without needing modifications to the applications or the library code they use.
In this talk, we walk through adding new functionality to Go, starting by showing how Go’s tooling makes it simple to create and maintain a fork. How we can add new functionality to the runtime library, and modify core Go concepts, such as Go routines to carry additional information. We’ll then use this knowledge to build a demo version of a distributed tracing system which can perform request tracing all the way from a HTTP request hitting an API server, going through multiple micro-services to a query being made to your database server.

JSON Web Token (JWT) is an open standard for securely transmitting information between parties as a JSON object. JWT is widely used in modern applications as a stateless authentication mechanism. Therefore, it is important to understand JWT security risks, especially when broken authentication is among the most prominent security vulnerabilities according to the OWASP Top 10 list.
This talk guides you through various security risks of JWT, including confidentiality problems, vulnerabilities in algorithms and libraries, token cracking, token sidejacking, and more. In live demos, you’ll learn how to hijack a user account exploiting common security vulnerabilities on the client-side, on the server-side, and in transport. You’ll also find out about common mistakes and vulnerabilities along with the best practices related to the implementation of JWT authentication and the usage of available JWT libraries. See Less |

Unit tests are the bread and butter of any project's quality assurance process. We software developers have been used to writing them and measuring code coverage in our continuous integration pipelines for years. There is tooling that helps us find untested areas, records the coverage percentages, and notifies us if the changes cause a drop in the test scope. Still, one can not test all features thoroughly with unit testing in all projects. Sometimes mocking the external functionality is so laborious that wasting the team's resources on creating the mock code doesn't make sense. Or it may even be impossible to reproduce the external functionality with the mockups.

As developers we know we have to write tests, but we also mostly hate this part of the job––many times because we just don't know where to get started. If you want to get the basics through some advanced use cases of testing in Go - this is the talk for you!
In this talk we'll provide some good working practices for how to write good tests for your Golang apps. We'll start with the basics of unit testing, how to avoid tests that behave non-deterministically, as well as avoiding race conditions. We'll walk through how to incorporate a linter for good, clean code practices and testing, and how to leverage mocks and interfaces (high level design patterns). We'll wrap up with a practical example of how to properly automate and set up your tests so they run correctly through a Github Actions example. See Less |

How can your company help developers to fly, but not crash down? The answer is platform engineering, which is the discipline of building self-service internal developer platforms (IDPs) to simplify software delivery for product teams. In this talk, you will learn how platform engineering evolved from the DevOps movement and what principles and best practices make a good implementation. Finally, we take a look at reference architectures that can power your platform.

The Go compiler is an excellent but complex tool. For most Go programmers, it’s just that - a tool. It doesn’t matter what happens between my "go build" and the execution of my binary because the go compiler works like a charm. But if you are a curious person that wants to know more about this process, this is probably your talk.
I’ll go through the whole process of the compilation of one of the most straightforward go programs that you can write: a hello world. From that source file, with just plain text, into an optimized machine-specific binary code, passing through the transformations in between. See Less |
