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.

One Postgres for Your App and Your Metrics — TimescaleDB extends the Postgres you already run so high-volume metrics and events stay queryable at scale. Hypertables, up to 95% compression, continuous aggregates. One database to operate, not two. Get $1000 credit to start.

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.

My Thoughts on the Future of Go in the AI Era — Akin to Steve Francia's recent piece, Alex argues that "AI might actually make boring languages more valuable, not less."
