Cogent Core: A New GUI Framework for Go — A new GUI framework with a “code once and run everywhere” promise for multiple platforms. It aims to be simpler to use than Gio and more powerful than Fyne. Curiously, Cogent’s web site itself is built in the framework and compiled to WASM to work on the Web. There’s also ▶️ a quick screencast pitching you on the framework.

Build Your Own SMTP Server in Go — The actual code here isn’t low level, but it's a good practical guide to some of the technologies around sending e-mail, like SMTP, DKIM, and SPF. The go-smtp library ultimately does the heavy lifting.

What’s New in Go 1.23: Iterators and reflect.Value.Seq — Carlana explains four of the functions around generic custom iteration that she proposed, comparing the new code to something she wrote ten(!) years ago using channels. If 2022 was all about generics, is 2024 the year of iterators?

Editor: A Source Code Editor in Pure Go — Curiously billing itself as a “simple but advanced source code editor”, it works on Linux, Windows and macOS (under X server) and certainly has that old school Unix vibe going on. Clearly a serious labor of love after some seven years of development.
