(OK, since you asked, I needed it to implement the software project planning language for [DoomCheck](https://www.doomcheck.com/)). Just as I finished, the first beta release of Go with generics came out, so I did it all again! 4 | 5 | Now I’m here to take you on the same journey. Not the Markdown part – Markdown is a parsing nightmare – the parser combinators part. 6 | 7 | Parser combinators are a composable way of building parsers in code; they stand in contrast to traditional parser generators like goyacc. They work particularly well in Go now that Go has generics, and they are remarkably easy to implement from scratch. In this tutorial, I’ll do a quick introduction to parser combinators, show you how to use a few primitives to implement a parser for a microlanguage, and dive under the abstraction layer and show you how to implement all the primitives -- each in just a few lines of Go. I aim to give you an appreciation for both parser combinators as an approach to parsing, and for how much better Go generics have made life. 8 | 9 | Finally, while I have had a great experience with Go generics overall, there are some frustrating limits around how you can use generics, so in the wrap-up, I will briefly talk about how future versions of Go could increase generics usability for this sort of domain. 10 | 11 | ### [Presentation](https://docs.google.com/presentation/d/1PfFFXjguakJM13tHWkFxFcy4wee65B26T9Cij2TWC0w/edit#slide=id.g15a27a86b97_0_76) 12 | 13 | ### [Youtube Video](https://www.youtube.com/watch?v=x5p_SJNRB4U&t=442s) -------------------------------------------------------------------------------- /JesúsEspino-HelloWorldFromTheCodeToTheScreen/Hello World, from the code to the screen.pdf: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/gophercon/2022-talks/4f40cabec7e2e045d083d0884cda56125ebf5d3d/JesúsEspino-HelloWorldFromTheCodeToTheScreen/Hello World, from the code to the screen.pdf -------------------------------------------------------------------------------- /JesúsEspino-HelloWorldFromTheCodeToTheScreen/README.md: -------------------------------------------------------------------------------- 1 | # Hello World, from the code to the screen 2 | 3 | Jesús Espino 4 | 5 | [Github](https://github.com/jespino) | 6 | [Twitter](https://twitter.com/jespinog) 7 | 8 | The Go compiler is a great tool, but sometimes it looks like magic.

We’ll dig into these network programming concepts by exploring the architecture of the popular open source chaos testing tool Toxiproxy. Toxiproxy is a tool written in golang that Shopify uses to intercept, manipulate, and disrupt TCP streams in a controlled manner in order to test the resiliency of applications and analyze their failure modes. We’ll talk about why Go is a great choice for networking tools, and discuss what aspects of the language make it especially easy to be productive writing tools such as this. Finally, Jordan will demonstrate how simple it is to get started in network programming with a live demo where he’ll build a bare-minimum clone of Toxiproxy that can intercept and add latency to TCP streams between a client and server. 8 | 9 | ## Speaker 10 | 11 | ### Jordan Neufeld, Senior Site Reliability Engineer - Shopify 12 | 13 | Jordan Neufeld is a Senior Site Reliability Engineer with over 6 years' experience supporting a wide range of technologies.

As our system is described, key topics will be introduced that you’ll need, to understand distributed systems in practice (e.g. replication, consistency, and consensus). We will walk through how our team leveraged tools like gRPC, Kubernetes, LevelDB, and Prometheus to implement two new open source projects that serve as the heart of our system. Confessions of all the ways we messed up will also ensue — from struggling to debug protocol buffer errors, to tangling up send and receive goroutines, to reasoning about the phases of replication. Finally, Rebecca will explain why rolling out their own system made sense for their use case, and why it might also make sense for you. It won’t be the prettiest story, but we hope you’ll benefit from the lessons we learned, including the most important one — that you can build your own distributed system. 6 | 7 | 8 | ## Slides 9 | 10 | A PDF copy of the slides could be found [here](./slides.pdf) 11 | -------------------------------------------------------------------------------- /RebeccaBilbro-HowtoBuildaDistributedSystem/slides.pdf: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/gophercon/2022-talks/4f40cabec7e2e045d083d0884cda56125ebf5d3d/RebeccaBilbro-HowtoBuildaDistributedSystem/slides.pdf -------------------------------------------------------------------------------- /RobertBurke-HowApacheBeamMakesYourDataProcessingGo/MakeYourDataProcessingGo-slides.pdf: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/gophercon/2022-talks/4f40cabec7e2e045d083d0884cda56125ebf5d3d/RobertBurke-HowApacheBeamMakesYourDataProcessingGo/MakeYourDataProcessingGo-slides.pdf -------------------------------------------------------------------------------- /RobertBurke-HowApacheBeamMakesYourDataProcessingGo/README.md: -------------------------------------------------------------------------------- 1 | # How Apache Beam Makes Your Data Processing Go! 2 | 3 | Learn how Apache Beam uses Go to execute your code against distributed datasets. As a language, Go brings unique challenges to designing a data processing framework. No inheritance, and no built-in serialization are just the start! This talk will cover how the Apache Beam Go SDK overcomes these challenges using reflection, interfaces, and generics to efficiently execute your data pipelines on arbitrary Beam Runners, like Apache Flink and Google Cloud Dataflow. 4 | 5 | ## Speaker Details 6 | 7 | - Name: Robert Burke 8 | - GitHub: [@lostluck](https://github.com/lostluck) 9 | 10 | ## Video 11 | 12 | A recording of the talk is available [here (youtube link)](https://www.youtube.com/watch?v=Z-GBHh6Kb-o). 13 | 14 | ## Slides 15 | 16 | A PDF copy of the slides can be found [here](./MakeYourDataProcessingGo-slides.pdf). 17 | -------------------------------------------------------------------------------- /SamanthaCoyle-AJourneyThroughIntegrationTestingWithGo-WhatCouldGoWrong?/README.md: -------------------------------------------------------------------------------- 1 | # A Journey Through Integration Testing with Go - What Could Go Wrong? 2 | 3 | When our team set out to conquer the world and perform integration testing for our project, we arrived at an impasse. The typical flow we've experienced uses the Python Robot framework but being Go developers we chose to take a risk for our org in hopes that it would pay off. 4 | 5 | Our team's use of Testcontainers for Go and go-test-report helped us to spin up our services, do some exciting integration tests, and create a nice test report html page for a good UX. Everything was working honky-dory until it was noticed that the tests all passed, but the test report tool showed a red failing status for passing tests. Yes, you read that right - this seemed suspicious. 6 | 7 | This was the first of a few problems we encountered on our journey; from limitations with some open source pkgs we used to disagreements between developers and our validation engineer on when code should be deemed as passing our validation standards. Come along in our journey to find out what our issues were and how we went about alleviating them. 8 | 9 | ## Samantha Coyle 10 | 11 | [Personal Website](http://samcoyle.me/) | 12 | [Github](https://github.com/sicoyle) | 13 | [Twitter](https://twitter.com/thesamcoyle) | 14 | [LinkedIn](https://www.linkedin.com/in/sam-coyle/) | 15 | [Medium](https://medium.com/@samcoyle) 16 | 17 | ## Resources 18 | 19 | [PowerPoint](./SamanthaCoyleGopherCon22.pdf) | 20 | [Testcontainers for Go Github](https://github.com/testcontainers/testcontainers-go) | 21 | [Go Test Report Github](https://github.com/vakenbolt/go-test-report) 22 | 23 | See y'all at GopherCon 2023! 24 | -------------------------------------------------------------------------------- /SamanthaCoyle-AJourneyThroughIntegrationTestingWithGo-WhatCouldGoWrong?/SamanthaCoyleGopherCon22.pdf: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/gophercon/2022-talks/4f40cabec7e2e045d083d0884cda56125ebf5d3d/SamanthaCoyle-AJourneyThroughIntegrationTestingWithGo-WhatCouldGoWrong?/SamanthaCoyleGopherCon22.pdf -------------------------------------------------------------------------------- /TakeshiYoneda-CGOlessForeignFunctionInterfaceWithWasm/README.md: -------------------------------------------------------------------------------- 1 | # CGO-less Foreign Function Interface with WebAssembly 2 | 3 | ## Abstract 4 | 5 | Foreign Function Interface(FFI) is a mechanism to invoke functions written in another language. In Go, there are only a few ways to achieve this, calling C functions via CGO, embedding Lua VM, etc. FFI is especially useful when we want to extend the existing Go projects by leveraging other programming languages’ ecosystems. 6 | 7 | WebAssembly(Wasm) is a relatively-new instruction format for a virtual machine, and numerous programming languages can be compiled down to Wasm binary format. Therefore, if there were a Wasm virtual machine that is embeddable in Go projects, executing Wasm binary in Go could be a way to achieve FFI in a secure and flexible way since Wasm is designed to be secure, and any programming language can have support for it. 8 | 9 | At Tetrate, we have open-sourced a WebAssembly runtime purely in Go called “wazero”. wazero is 100% compliant with the WebAssembly Core Specification 1.0 and 2.0. It has zero dependencies and doesn't rely on CGO. This means you can run applications in other languages and still keep cross-compilation, etc. The prime motivation behind wazero was to write a Wasm runtime purely in Go to avoid CGO usage since there was no pure Go Wasm runtime out there (except a few that are archived), therefore we were not able to achieve FFI via Wasm without CGO. 10 | 11 | This tutorial will cover the basics of WebAssembly, the state of the Go ecosystem around it, how CGO-less FFI with Wasm looks like through a live demo, a deep dive into the wazero’s WebAssembly to machine code compiler and the virtual machine implementation, and how Gophers can start leveraging CGO-less FFI in their project. 12 | 13 | ## Speaker Details 14 | 15 | - Name: Takeshi Yoneda 16 | - Twitter: https://twitter.com/mathetake 17 | - GitHub: https://github.com/mathetake 18 | -------------------------------------------------------------------------------- /TakeshiYoneda-CGOlessForeignFunctionInterfaceWithWasm/slides.pdf: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/gophercon/2022-talks/4f40cabec7e2e045d083d0884cda56125ebf5d3d/TakeshiYoneda-CGOlessForeignFunctionInterfaceWithWasm/slides.pdf -------------------------------------------------------------------------------- /TomLyons-HowIWriteHTTPClientsAfter(almost)7Years/README.md: -------------------------------------------------------------------------------- 1 | # How I Write HTTP Clients After (almost) 7 Years 2 | 3 | ## Abstract 4 | 5 | HTTP Servers have middleware. 6 | 7 | HTTP Clients have… nothing? 8 | 9 | Inspired by the well-known article and previous GopherCon talk “How I Write HTTP Services After 7/8 Years” by Mat Ryer, Tom aims to provide a rival paradigm for HTTP clients.

They wrote the storage and query engine from 10 | the ground up, then made it as fast as MySQL by using golang’s 11 | profiler. Join Zach as he shares what they learned on this journey. 12 | He will demo how to use golang’s profiler tools to uncover slowdowns 13 | in your code. He will also detail many examples of slow code from 14 | DoltHub’s own code base and show you how the team fixed them.
