This course will take you show you how to test, benchmark, and profile your Go code. Starting with basic testing, all the way through system and memory profiling. Continue even further by using and understanding flame graphs. Each attendee will receive a link 24 hours prior to the start of the workshop with links to all class material. Additionally, each attendee will receive a link after the workshop to the recording of the workshop as well.

Creating and scaling microservice via a distributed system is a complex and challenging effort. Protocol Buffers (Protobuf) and gRPC can quickly simplify this challenge, by easily defining your messages and services with Protobuf. These are small, simple, and fast data structures. Protobuf ships with idiomatic libraries written for most of the popular languages and platforms. With gRPC, you can start quickly, and scale to millions of RPC’s per second with ease. It also supports bi-directional streaming, integrated auth, tracing, load balancing, and more. In a nutshell, if you are embarking on a new system, or looking to extend an existing one, gRPC will allow you to accomplish that in small, manageable steps that will ensure a future system that is robust, fast, and scalable. By the end of this course, you’ll be able to create basic protocol buffer messages, design simple gRPC services and understand how to properly handle successful and unsuccessful rpc calls. Each attendee will receive a link 24 hours prior to the start of the workshop with links to all class material. Additionally, each attendee will receive a link after the workshop to the recording of the workshop as well.

In this 3-hour online master class, Buffalo creator and lead developer, Mark Bates will build a fully tested, complete, CRUD implementation for a resource, all while explaining each step of the process along the way. This master class will touch upon the following aspects of Buffalo: * Routing * Templating * Understanding buffalo.Resource * Testing Actions * Models * Validations * Migrations * more 24 hours before the virtual class will begin you will receive a URL for the online class. You will need zoom.us installed prior to the class start time. All registered attendees will receive a copy of the recorded session, as well as the source code, within a few days of the session ending.

Go modules are becoming part of our daily workflow as more and more projects adopt them. However, because they are still experimental, there is a lot of confusion around how to use them, upgrade from existing dependency management tools, and avoid common mistakes. In this 2 hour workshop, Mark Bates will walk through the following scenarios. ### Application Developer * adding modules to your app * switching from dep to mods * understanding `go mod` commands * working inside and outside the gopath ### Package Maintainer * adding modules to a package * upgrading a package to v2+ * upgrading an existing v2+ * using the replace directive

Go is a modern programming language with a heavy focus on developer productivity, scalability, and speed. Whether you're a recent grad or an industry veteran, there's no better time to learn the core concepts of the Go programming language. This course introduces language fundamentals, such as primitives, language structure, design, and concurrency. If you have little or no experience with Go and want to jumpstart your knowledge, this course is for you. ### This course is for you because... * You want to review the Go language to see if it's something that will work for you and your team’s next project. * You currently develop in another language and are interested in learning how Go handles similar constructs and how it's different. ### Prerequisites * A working knowledge of a modern programming language (Java, Ruby, Python, C, C++, C#, Perl, etc.) * A basic understanding of operating system concepts and environment variables * Experience working with a command shell and navigating a filesystem
