Go Blueprint: A Quick Way to Start Go Projects ⚒

The tool helps you setting up new Go projects fast, with ready-made templates and all the basic setup done for you.

While I’m not really into using tools like this, some might find it useful to save time and focus on development.

From the authors: "Powerful CLI tool designed to streamline the process of creating Go projects with a robust and standardized structure. Not only does Go Blueprint facilitate project initialization, but it also offers seamless integration with popular Go frameworks, allowing you to focus on your application's code from the very beginning."

Coming in Go 1.24: testing/synctest experiment for time and concurrency testing

Testing code that involves time or concurrency can be a struggle. It often leads to hard-to-debug flakes in CI or long-running tests.

Go 1.24 is scheduled to be released in February and the release freeze has begun.

It’s set to include an experimental testing/synctest package designed to make testing code that involves time or concurrency precise and fast.

Go 1.24: A Major Improvement for Tooling: go tools 🛠

Hello, folks! The upcoming Go 1.24 (supposed to be coming this month, Feb 2025) introduces a new go tool command, aiming to significantly improve the way project-specific tools are managed. This update eliminates the need for the tools.go workaround, reduces dependency bloat, and improves performance through caching. So,
- No more tools.go hacks
- Faster execution with caching
- Cleaner and more efficient dependency management

How it works? Simple!

Add a tool:

go get -tool github.com/oapi-codegen/oapi-codegen/v2/cmd/[email protected]

Run it:

go tool github.com/oapi-codegen/oapi-codegen/v2/cmd/oapi-codegen --config=config.yaml openapi.yaml

List available tools:

go tool

Some people say this is one of the most useful changes to Go's tooling in years, making project setups more efficient and maintainable, so take a look in more details here https://www.jvt.iss.one/posts/2025/01/27/go-tools-124/ 🚀

PS More official docs can be found in the Go 1.24's release notes here: https://tip.golang.org/doc/go1.24#tools

Be Careful with Go Struct Embedding

Embedding structs can quietly mask deeper-nested fields: a duplicate field name isn’t ambiguous unless it appears at the same ‘depth’, meaning your program may choose an unintended value.

Hello, folks, it's been a while. Re-sharing an interetsting recording from GopherCon 2025:
Advancing Go Garbage Collection with Green Tea (youtube). TL;DR:

Go 1.25 includes a new experimental garbage collector called Green Tea, available by setting GOEXPERIMENT=greenteagc at build time. Many workloads spend around 10% less time in the garbage collector, but some workloads see a reduction of up to 40%!

There is an also official text version on the Green Tea Garbage Collector if one does not like to watch the video.

Thanks!
