sync.Pool is Not a Silver Bullet — sync.Pool can reduce allocations and GC pressure, but it’s not a drop-in solution for every case. Jens looks at where pooling shines (predictable, short-lived objects) and when it can backfire.

Vite Backend Integration for Go — A way to integrate a Vite-based frontend with a Go-based backend app.

Fuzzing Go Binaries with LibAFL — Built upon the Rust-powered LibAFL fuzzing library, GoLibAFL brings ‘state-of-the-art fuzzing techniques’ to Go developers. This post compares it to existing solutions, shows off some examples, and digs into how they tailored LibAFL for Go use cases.

Bufstream: Robust Streaming for gRPC — Meet a cloud-first Kafka implementation custom-built for go gRPC streams. Plus, Bufstream is Jepsen‑tested.

Mockery v3: Create Mock Implementations of Interfaces — With the very bold claim of Mockery v3 being able to make “obsolete all other interface-based code generation frameworks” in the Go world, the author has a good go at explaining why. If you’d rather just see the facts and give it a go, the homepage is a good place to start.

Hoard of the Rings: Extracting Data From a Cheap Activity Tracker — Tony picked up a cheap activity tracking (heartrate, steps, etc.) ring and figured out how to use TinyGo to read its outputs. A fun yet practical use for TinyGo!

Using Signals with Go — Signals are asynchronous messages sent to processes to notify them of events like interrupts, crashes or termination, or to trigger certain behaviors. Most languages let you catch signals and act upon them, such as for shutting down a program gracefully, and Go is no exception.

Complete Go for Professional Developers — Craft production-grade APIs with Go, the language trusted by tech giants! Connect to Postgres, implement auth, and write tests that matter. Taught by a Twitch ML engineer who solves real problems with Go daily.

go-i18n 2.6: Translate Your Go Program Into Multiple Languages — A package and tool for translating Go programs into different (natural) languages. v2.6 now requires Go 1.23+.

Genanki: A Go Library for Generating Anki Decks — Anki is a popular tool for flashcard, spaced attention style learning.

Go Panicked Again? Yeah, Sentry Saw It—and Kept the Receipts — Goroutines are great—until one quietly dies. Sentry catches panics, traces them back, and gives you full context. 👉 Try it free before your next deploy gets weird.

Faster Shuffling in Go with Batching — Put down that deck of cards.. ‘shuffling’ here refers to moving the contents of an array about. It is based on expensive random integer generation. Here, Daniel offers up a couple of algorithms that speed things up by 2-3X compared to Go’s standard Fisher-Yates shuffle.

More Predictable Benchmarking with testing.B.Loop — Go 1.24 introduced a new way to write benchmarks that avoids common pitfalls like accidental dead-code elimination and inaccurate timings. If you want faster, more accurate, and more intuitive benchmarking, this is for you.

Does Your Postgres Database Feel Like a Black Box? — Are you prepared for the next high-traffic event? Join us April 16 to explore pganalyze features that tune slow queries, catch regressions, and keep Postgres running at its best.

Life as a Go Developer on Windows — Go officially supports Windows as a first-class platform, but supporting a product across numerous operating systems still requires some work. For Windows that means juggling WSL quirks, file system oddities, toolchains, and platform-specific code.

Porting Tailscale to Plan 9 — A fun story from former Go core team member Brad Fitzpatrick on Tailscale’s April Fools’ Day project to port Tailscale to Bell Labs’ 1980s Plan 9 OS. It was no joke, though, and actually works, despite the Go compiler’s support for Plan 9 having some “bitrot.”

Chroma 2.16: Pure Go Syntax Highlighting — Take source code and turn it into syntax highlighted HTML, ANSI colored text, or just grab the raw tokens in JSON. Brings most of the features of Pygments to Go and can use Pygments’ lexers and styles too. There’s an online playground where you can try it out.

GitHub MCP Server: GitHub's Official MCP Server — As the Model Context Protocol continues to move toward industry-standard status for giving AI agents more powers to interact with things outside their usual sandbox, GitHub has released its official server, which you can integrate with VS Code and Claude Desktop. It supports loads of tools for issues, PRs, repos, and more.

A Guide to Optimizing for High Performance in Go — An in-progress collection of technical articles aimed at helping Go developers write faster, more efficient apps. The initial focus is on common patterns like object pooling, struct field alignment, and using worker pools, with a guide to high-performance networking set to follow soon.

asciigraph: ASCII Line Graph Rendering Library — A longstanding library for rendering basic line graphs in ASCII text, such as at the terminal, all with no dependencies.

Revive 1.8: A Faster, Configurable, Flexible Linter for Go — A drop-in replacement of golint that aims to provide a little more structure, configurability, and performance. It’s used by numerous large Go projects and libraries. The README on the GitHub repo explains how it differs to golint.

urfave/cli 3.1: A Declarative Way to Build Go CLI Apps — The manual outlines all of the key features, but think shell auto-completion, option parsing, help text, etc.

Introducing ls-lint: A File Structure Linter — Billing itself as an ‘extremely fast file and directory name linter’, ls-lint is a Go powered tool for enforcing some structure over a project’s filesystem and naming policies. GitHub repo.

When is it OK to Panic in Go? — One of the Go proverbs is “Don’t panic,” which isn’t just good life advice but also saying not to use panic for normal error handling. Alex explores panic and some times when you should use it.
