Go 1.26's new garbage collector: measure before you upgrade

The piece to sit with covers Go 1.26's new garbage collector, now on by default, and argues the gains are real but unevenly distributed, so it walks through what to measure on your own workload before flipping the switch. It pairs nicely with a separate write-up on real-world Go versus benchmark obsession, which makes much the same point from the other direction. Elsewhere there is a practical guide to graceful shutdowns for Go services on Kubernetes, and a nicely odd project building an append-only log directly on object storage, no broker in sight.
