How I Use HTMX to Build Go Webapps (https://golangweekly.com/link/188127/rss) — A walkthrough of practical patterns for using htmx (https://golangweekly.com/link/188128/rss) (think AJAX-style updates driven by HTML attributes) with Go. Opinionated, very Go-specific, and honest about the tricky bits. A good starting point for building server-rendered interfaces with incremental interactivity.

One Postgres for Your App and Your Metrics (https://golangweekly.com/link/188126/rss) — TimescaleDB extends the Postgres you already run so high-volume metrics and events stay queryable at scale.

Compile-Time OpenTelemetry Instrumentation for Go (https://golangweekly.com/link/188129/rss) — 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) (https://golangweekly.com/link/188130/rss) – there's an update! It's a likely decline but comments are open. The more recent conditional expression proposal (https://golangweekly.com/link/188131/rss) 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 (https://golangweekly.com/link/188132/rss) inside comments.

The code is open source, though, and on GitHub (https://golangweekly.com/link/188135/rss).

-
Reddit's /r/golang discussed the situation where passing structs by value is faster (https://golangweekly.com/link/188136/rss) than passing pointers.

My Thoughts on the Future of Go in the AI Era (https://golangweekly.com/link/188138/rss) — Akin to Steve Francia's recent piece (https://golangweekly.com/link/188139/rss), Alex argues that "AI might actually make boring languages more valuable, not less."

NEW GO PROPOSALS:

-
Go co-designer Robert Griesemer has made a proposal to add a StringLen function to go/constant (https://golangweekly.com/link/184631/rss).

-
Should error message text be explicitly excluded (https://golangweekly.com/link/184632/rss) from the Go 1 compatibility promise? The proposer cites a comment in net/http (https://golangweekly.com/link/184633/rss) saying an error message can't be changed as evidence of the current ambiguity.

-
🔒 Neal Patel of the Go security team proposes adding 'profiles' to crypto/tls (https://golangweekly.com/link/184634/rss) that bound what the rest of tls.Config's vast array of settings can do.

Gojit: A Revived JIT Compiler in Go (https://golangweekly.com/link/184635/rss) — Go’s AOT compilation makes JIT unnecessary in most cases, but what if you’re writing an emulator or interpreter that would benefit? This post revives a 2014 experiment (https://golangweekly.com/link/184636/rss) for modern Go and solves the problem of letting JIT-generated code call back into Go functions without crashing the GC.
