Proposal: Don't Add Generics to Go's Core Libraries in 1.18 — Rob is suggesting that new versions of the core libraries be placed in the experimental namespace so folks can test them before core gets ‘genericized’. The idea is that while we get generics in 1.18, we can take more time to figure out how the core libraries will use them.

Rob Pike

"How to use these ideas in the standard library requires great thought and planning. Putting them in the library now also adds a significant burden to rolling out the release. I propose that we do not update the libraries in 1.18."

'Hey Linker, Can You Spare a Meg?' — Tailscale, a mesh VPN service, has its core code written in Go, but on iOS their network extension is limited to a mere 15MB of memory. Ensuring they stayed within this limit involved the Tailscale engineers digging deep into Go’s runtime, garbage collector, and more, ultimately resulting in improvements for all Go users coming to Go 1.18.

GoReleaser Can Now Create macOS Universal BinariesGoReleaser is a popular tool for cross-compiling and releasing Go projects. Universal binaries are necessary on macOS now due to supporting both amd64 and arm64 architectures with Apple’s new chip releases (i.e. the M1).


Safer Enums in Go — For those of us that give more than an iota about enums, this post is a nice exploration of ways to make them better (integers bad, strings good) but certainly not perfect.

GoPlus (Go+): A More Scripty Variant of Go — It’s not going to win any awards for having a good, non-confusing name, but the overall idea of having a Go compatible language that leans more towards Python-style simplicity for scripting and data science use cases is interesting nonetheless.
