Training Classes
Note: This material has been designed to be taught in a classroom environment. The code is well commented but missing some of the contextual concepts and ideas that will be covered in class.
Ultimate Go
This is material for any intermediate-level developer who has some experience with other programming languages and wants to learn Go. We believe these classes are perfect for anyone who wants a jump start in learning Go or who wants a more thorough understanding of the language and its internals.
Ultimate Web
This is material for any Go developer who wishes to learn how to build robust and well tested HTTP based applications in Go. This class provides an intensive, comprehensive and idiomatic view build Web, SOA, and API applications using Go.
Ultimate Data
This is material for any Go developer, data scientist, analyst, or statistician who wishes to learn how to build robust data science applications in Go. This class provides an intensive, comprehensive and idiomatic view on building predictive models, analytics engines, components of data pipelines, and more using Go. We believe this class is perfect for anyone wishing to build data-driven applications that produce valuable insights, have reproducible behavior, and can be deployed within modern architectures.
NATS
This is material for anyone looking to learn more about or use NATS to building highly scalable and distributed systems. NATS acts as a central nervous system for distributed systems such as mobile devices, IoT networks, enterprise microservices and cloud native infrastructure. Unlike traditional enterprise messaging systems, NATS provides an always on ‘dial-tone’.
