Minecraft From Scratch: A Simple Go Minecraft Clone — A fun project to replicate Minecraft’s infinite, procedurally-generated navigable landscapes using Go and OpenGL 4.1 (as provided via the go-gl/gl bindings – yes, cgo is required here).

How to Manage Tool Dependencies in Go 1.24+ — We’ve touched on the new go tool subcommand a few times before, but this is a bit more usage-focused and includes a nice tip about separating your tools into their own module file.

GoChromecast: Discover Devices and Stream Media to Chromecast Devices — A Go-powered tool that implements the protocol used by Chromecast devices.

Testing Concurrent Code with testing/synctest — Concurrency is one of Go’s natural strengths, but testing heavily concurrent programs can be tricky. Go 1.24 introduces a new (though experimental and hidden behind an environment variable) package for testing code involving time or concurrency. The Go team wants you to have a play and send in your feedback.

Extensible Wasm Applications with Go — “… the ability to build a WASI reactor and export Go functions to Wasm in Go 1.24 represent a significant step forward for Go’s WebAssembly capabilities. These features empower developers to create more versatile and powerful Go-based Wasm applications …”

Go 1.24 Released — Finally, after many months of blog posts getting excited about Go 1.24’s new features, the real deal has arrived. It’s a reasonably big release too, including a lot of updates:

Reduce Your Apache Kafka Costs + Ops Burden With WarpStream — WarpStream reduces Kafka costs by 80+% by eliminating disks and interzone networking fees and features zero ops auto-scaling. It runs in your private cloud and data is stored in your object storage buckets, so raw data never leaves your environment.

Go Slice Gotchas — “Just like any other dynamically growable container structure, slices come with a few gotchas. I don’t always remember all the rules I need to be aware of, so this is an attempt to list some of the most common mistakes I’ve made at least once.”

We Replaced Our React Frontend with Go and WebAssembly — Even if you wouldn’t want to do this, it’s interesting to read about the experience of a team that has.

sturdyc: Caching Library with Advanced Concurrency Features — “A sturdy gopher shielding data sources from rapidly incoming requests.” Designed to avoid cache stampedes and overloading in high throughput systems by providing non-blocking reads and sharded writes for minimal lock contention.

go-taskflow: A Taskflow-Like DAG Task Execution Framework — A general-purpose task-parallel framework for Go, suitable for complex dependency management in concurrent tasks.

Proposal: math/rand/v2 Worked, Let's Do sync/v2! — Creating ‘v2’ versions of standard packages is Go’s compromise for modernization vs stability. With the evolution of math/rand a success, Ian thinks synchronization primitives are due an upgrade too. Much of the value here comes from a month’s worth of discussion, including people’s discontent over the ‘v2’ approach (outlined further here).

A Minesweeper Game Written in Go — A cute example of putting together a game in such a way that it not only runs on the desktop in the usual way, but can be taken to the Web too. The effects are cute, too – this is a great use of the Ebitengine game engine. The GitHub repo is certainly worth a look if...

etree 1.5: A Library to Parse and Generate XML Easily — A simple, straightforward approach to working with XML in Go, inspired by Python’s ElementTree. XML documents are represented as trees for easily traversal and you can create, import, modify and save XML. Queries can be done with a XPath-like approach.

httptap: View HTTP/HTTPS Requests Made by Any Linux Program — It uses Linux-only network namespaces for now, but this is a Go-powered process-scoped HTTP tracer you can run without root privileges. It even decrypts TLS traffic by generating a CA on the fly. Handy for debugging or seeing if dependencies or apps are ‘phoning home,’ perhaps..

Upcoming Workshop on Building Backend Web Apps in Go — Join us for a two day workshop (either online or in person) and develop your Go know-how. We'll focus on using Go to build backend web apps, along with learning Go data structures, interfaces, how to write unit tests, and more.
