strace example

Using the Kindle version of this book.

The "strace" example lacks enough context to figure out how to run it. The example command shown is:

$ strace ./main

There is no file named "main". There is no instructions on how to make it. I figured out that I needed to build web-server.go (instead of "go run web-server.go" as shown in Chapter 1). So I did it like this:

$ go build web-server.go
$ strace ./web-server
