Applied Go

WaitGroups are a means of synchronizing goroutines; yet the Add()/defer Done() idiom feels clumsy and is error-prone. A new method, Go(), puts an end to goroutine counting.

Programs in the Go Playground can print text to a space below the code editor. With a simple trick, you can even output PNG images.

Compiling Go code into a WebAssembly module is easy as pie. Getting the code to interact with the browser requires a few lines of Javascript, but it's less complicated than you might think.

The Go team develops a new garbage collector algorithm suitable for multicore CPU architectures and non-uniform memory. You can try it now!

Security is more crucial than ever. Making security an afterthought is a footgun. Learn how to write secure Go code from the start.

After a long (and exciting) journey through umpteenth of programming languages, I arrived at Go and finally feel at home.

Programming language theory doesn't rule out import cycles ... but this doesn't make them a good idea.

Go's templates allow defining custom functions for use inside the template. Nice, but type safety gets overboard. Are they still worth using?

This happens when JSON and CSV have a baby. (And how your Go code can benefit from it.)

Letting an LLM code some tool in Go can be nice, especially when it uses tools via MCP. But there are some risks involved.
