In other Go projects or documentation you might sometimes see network addresses written using named ports like":http"or":http-alt"instead of a number. If you use a named port then Go will attempt to look up the relevant port number from your/etc/servicesfile when starting the server, or ...

currently whether a symbol of a function or global variable with the same name is deduplicated depends on the specific behavior of the system's dynamic linker. It may behave differently from one platform to another (e.g. on Linux and on macOS). Plugins are designed carefully with that in ...
into the slice of files by repeating same flag multiple times. FileList will validate that files exists and will attempt to open them with provided privileges. To be used like this$ progname --log-file /path/to/file.log --log-file /path/to/file_cpy.log -l /another/path/to/file.log ...

When calling a function from within another function, the defer statement can be used to defer, or postpone, the execution of a function until the surrounding function finishes running. It is typically used for resource management, for example, waiting until after a file is read before closing ...

Another convention is that the package name is the base name of its source directory; the package in src/encoding/base64 is imported as "encoding/base64" but has name base64, not encoding_base64 and not encodingBase64. The importer of a package will use the name to refer to its content...
This unusual property is pure pragmatism, making it easy to use a single err value, for example, in a long if-else chain. You'll see it used often. § It's worth noting here that in Go the scope of function parameters and return values is the same as the function body, even though...
