The first big release of the year was the macdriver project, which got a significant response on Hacker News. It gives us Objective-C and Apple framework bindings for Go, letting you build simple Apple apps entirely from Go. That wasn't possible before, so it was a little exciting, but it was early. The native Go APIs included for commonly used Foundation and Cocoa classes were far from complete. They could still be used if you knew what you were doing, but with an ideal of total coverage of Apple frameworks, that wouldn't be enough. There were also unresolved issues just deciding how to best manage memory and pointers, which I knew would fall on me to figure out and take some time.

With the macschema toolchain, you can generate API schemas about any Apple framework, class, function, etc based on their documentation and header declarations. This is useful for us in generating framework bindings in macdriver, but it would be useful for any project doing similar work, such as bindings for other languages. This sort of approach will play a big part in how Tractor will integrate with "whatever we want" down the line.

Along the way, I released a few demos for macdriver to make clear the possibilities and provide reference examples. One of them I spun off into a standalone project called topframe, which is also serving as a test bed for how we are doing cross-platform support. More on that in a moment.

qmux
wire protocol for multiplexing connections or streams into a single connection, based on a subset of the SSH Connection Protocol
Unrelated to macdriver, I released a protocol called qmux with a post explaining why this (but really any) muxing protocol, including and especially QUIC, is such a great primitive for network programming. The project came with two implementations, Go and TypeScript, with more on the way. The post about it was the first explainer article I'd done in a while and people liked it. This was important because the idea behind it was really more valuable than the protocol itself, but regardless we still need implementations of it to exist. To show the idea in action, I built a 130 line version of Ngrok, which turned into a great post walking through how it works.
