• A Proposal to Add Generic Methods to Go: A new language proposal explores allowing generic methods (not just generic functions), revisiting a long-standing limitation tied to how generics interact with interfaces and method calls.

• Floating-Point Printing and Parsing Can Be Simple and Fast: Russ Cox walks through modern, high-performance float parsing/formatting algorithms in Go, with the expectation that a version of this work could land in Go 1.27.

• 😱 Panic Recovery: A practical guide to panic/recover, focusing on real-world gotchas and safe recovery patterns encountered in production systems.

• Dancing Backwards with Go: A fun, beginner-friendly TDD walkthrough showing how writing tests first helps you design cleaner Go functions and refactor with confidence.

• A Rust Developer’s Honest Review of Go: A Rust developer shares a candid take after a few months with Go, highlighting what feels great (simplicity, productivity) and what feels limiting (types/error patterns).

• Writing a Time Series Database from Scratch in Go: A slide deck on building a TSDB in Go, from core data structures through storage/ingestion considerations (VictoriaMetrics context).

• On Starting to Write a Compiler in Go: A concise guide to building a small compiler pipeline in Go, motivated by reducing boilerplate and making compiler experimentation more approachable.

💻 Code

• Google’s JSON Schema Package for Go: Google has open sourced jsonschema-go, a full JSON Schema implementation for Go with schema creation, (de)serialization, validation, and schema inference from Go types. Used in Google’s official Go SDK for MCP.

• go-quickjs-wasi-reactor: Run QuickJS Efficiently Under Go: Embed QuickJS-NG compiled to WASM (WASI reactor model) inside Go apps, enabling efficient JS execution with a controllable event loop and IO polling.

📦 Code Releases

• mactop v2.0.8: A Mac-only, terminal “top”-style monitor for Apple Silicon, showing real-time CPU/GPU usage plus power, memory, temps, and other SoC metrics.

• Echo 5.0: Echo’s v5 release is mostly a maintenance update, but it includes major breaking API changes (notably a redesigned Context, a new Router interface, and logging changes).

• ✉️ Notifuse v26: An AGPL-licensed, self-hosted email platform for designing and sending newsletters and transactional email, positioned as an open-source alternative to tools like Mailchimp.

• 🤖 grepai 0.21.0: A privacy-first semantic code search CLI that indexes code using vector embeddings, letting you query by meaning (natural language) rather than exact strings.

• Google API Linter v2.2: A linter that performs real-time checks to ensure protobuf-defined APIs follow Google’s API standards (AIP).

• Sonic 1.15: ByteDance’s ultra-fast Go JSON encoder/decoder, accelerated with JIT and SIMD for high-throughput JSON workloads.

• 🤖 Crush v0.34.0: Charm’s terminal-based AI coding assistant (“coding bestie”), with this release focusing heavily on improved non-interactive usage via crush run.

• GoProxy 1.8: A Go library for building custom HTTP/HTTPS proxy servers, including programmable request/response handling.
