Applied Go

The new iterator functions in Go 1.23 replace an unwieldy loop construct with the familiar range syntax. Here is how.

What's better than learning by inspecting real code? These repositories can help you transition from 'I know Go' to 'I understand how to use Go'.

Passing values through channels is fine, but beware of passing (hidden) pointers between goroutines.

The go.work file manages local redirects of remote modules. It's specific to your machine, so don't add it to the repository.

Renaming a public module breaks all client code. Give your clients time to move over.

Or: don't hard-code your demo server port to 8080. Let it choose the next available port instead.

Instead of accessing your local dev servers through different port numbers, use Caddy to access them through separate domains.

Don't do this or you must go to bed without committing your code.

Unikernels can boot up rapidly and scale to zero to save energy and cost. A great basis for building efficient web-based tools.
