Kamal 2: Thou Need Not PaaS — Kamal is a container-based deployment tool from 37Signals, best known for their work on Ruby on Rails. It’s language agnostic though, and ▶️ the screencast demo shows off deploying a simple Go app quickly, before moving on to a Ruby example. Certainly a viable new deployment option for Go apps on self-managed servers.

Reflecting on Go Reflection — Truly a reflective opinion piece, and probably a divisive one too.

Distributed Transactions in Go: Read Before You Try — How to approach transactions that need to span more than one service.

Prep: Compile-Time Function Evaluation for Go — “By using prep.Comptime, you can evaluate functions at build time, replacing them with their computed results. Just like comptime from Zig.
