Telemetry in Go 1.23 and beyond 👾

Go 1.23 provides a new way for you to help improve the Go toolchain. By enabling telemetry uploading, you can elect to share data about toolchain programs and their usage with the Go team. This data will help Go contributors fix bugs, avoid regressions, and make better decisions.

Building LLM-powered applications in Go ❤️

The post explores various methods for setting up a Retrieval-Augmented Generation (RAG) server using different toolchains: Gemini + Weaviate, LangChain, and Genkit. Go’s inherent strengths appear to align well with the demands of the modern LLM/RAG ecosystem.

What's in an (Alias) Name? 🤓

Generic alias types are set to arrive in Go 1.24 (anticipated in February 2025) as part of this proposal, expanding on both type aliases and generics. One key use case for type aliases is enabling refactoring without breaking compatibility. Robert breaks down the fundamentals of type aliases and explains why integrating them with generics required additional effort.

Extensible Wasm Applications with Go 📆

Go 1.24 enhances its WebAssembly (Wasm) capabilities with the addition of the go:wasmexport directive and the ability to build a reactor for WebAssembly System Interface (WASI). These features enable Go developers to export Go functions to Wasm, facilitating better integration with Wasm hosts and expanding the possibilities for Go-based Wasm applications.

Testing concurrent code with testing/synctest 🤓

One of Go’s signature features is built-in support for concurrency. Goroutines and channels are simple and effective primitives for writing concurrent programs.However, testing concurrent programs can be difficult and error prone.

In Go 1.24, the go team are introducing a new, experimental testing/synctest package to support testing concurrent code. This post will explain the motivation behind this experiment, demonstrate how to use the synctest package, and discuss its potential future.

Faster Go maps with Swiss Tables 📆

Go 1.24 includes a completely new implementation of the built-in map type, based on the Swiss Table design. In this blog post we’ll look at how Swiss Tables improve upon traditional hash tables, and at some of the unique challenges in bringing the Swiss Table design to Go’s maps.

From unique to cleanups and weak: new low-level tools for efficiency ❤️

An overview of two new features in Go 1.24’s garbage collector: runtime.AddCleanup and weak.Pointer. Cleanups work similarly to finalizers but avoid some of their issues by not reviving the objects they are linked to. Weak pointers allow referencing objects without stopping them from being garbage collected.
