The GopherGuides held a full week of informative and engaging training at The New York Times that left our engineers excited and empowered to use Go. The classes were tailored to our needs so all levels of engineer came out with some new bits of Go wisdom. We at NYT look forward to using GopherGuides for future training!

Cory is excellent faciltator and proved to be extremely knowledgeable in Golang. I'd honestly take this session again. He is engaging and able to cover topics pertinent to specific instances.

I had a basic understanding of Go coming into this session. After this training I am able to understand how to apply topics such as concurrency and gRPC which will be helpful for my team.

This course provided experience and exposure to what Go can really do. I feel this is what most other training courses lack.

When generics landed in Go (golang) 1.18, they came with a rule that has annoyed people ever since: functions could declare type parameters, but methods could not. Go 1.27 removes that rule. A method can now declare its own type parameters, which makes patterns like chainable transformations possible for the first time. This was one of the most requested features in the language, and one of the most debated. In this article, we'll look at the problem, the fix, and the restrictions that come with it.
The encoding/json package is one of the oldest packages in Go (golang), and it shows. It matches field names case-insensitively, silently accepts duplicate keys, and marshals nil slices as null. We've all worked around these for years. Thankfully, Go 1.27 ships the fix: encoding/json/v2 graduates from experiment to standard library. It's stricter by default, significantly faster at unmarshaling, and your existing encoding/json code keeps working. In this article, we'll walk through what actually changes, by example.
Go (golang) 1.26 shipped in February of 2026. The headlines went to the Green Tea garbage collector and the new SIMD package. Those are great, but they aren't the changes you'll notice in your day to day code. The changes you'll notice are smaller: new now accepts an expression, errors.AsType gives us a generic errors.As, and slog.NewMultiHandler lets one logger write to many destinations. In this article, we cover each one by example.
