Compile-time OpenTelemetry instrumentation for Go

How I Use HTMX to Build Go Webapps — A practical walkthrough of using htmx (think AJAX-style updates driven by HTML attributes) with Go. Opinionated, super Go-specific, and honest about the tricky bits. A good starter on building server-rendered interfaces with incremental interactivity.

Compile-Time OpenTelemetry Instrumentation for Go — No more hand-written instrumentation or eBPF agents needed, as OpenTelemetry's compile-time instrumentation for Go is now stable. It uses -toolexec to inject telemetry automatically, but v1's library coverage has some limits worth noting.

IN BRIEF:

• 14 years ago Rob Pike proposed removing string(int) – there's an update! It's a likely decline but comments are open. The more recent conditional expression proposal is also looking likely to suffer a similar fate.

• go fmt and go doc are set to no longer rewrite straight quotes into 'smart' quotes inside comments.

• 🕹️ Luigi Vanacore has released Beginning Game Programming with Go, a (paid) book about building a complete game using Ebitengine. The code is open source, though, and on GitHub.

• Reddit's /r/golang discussed the situation where passing structs by value is faster than passing pointers.

• url.MustParse has been accepted.

💡 The New Stack shares some more background on the project, pointing a finger at Anthropic and OpenAI for not yet supporting Go directly with their similar SDKs.

• 🔒 Tinyauth 5.1 – Tiny authorization and authentication server. v5.1 marks it becoming officially OpenID Connect™ Certified and adds support for auth through Tailscale and deny-by-default access controls.

• Echo 5.3 – The popular web framework adds support for the new HTTP QUERY method and adds a mechanism to automatically handle HEAD requests on GET endpoints.

• THUNDERSNAP – A new library from Tailscale for replicating, forking, and sharing container snapshots. More here.

• Tetra3D 0.18 – PS1/N64-inspired Ebitengine-based hybrid 3D renderer.

• Gofeed 1.4 – A robust library for parsing RSS, Atom and JSON feeds.
