principles Build a simple web server How Go works with web Get into http package Summary HTTP Form Process form inputs Validation of inputs Cross site scripting Duplicate submissions File upload Summary Then we install Go using the following commands: gvm install go1.8.3 gvm use go1.8.3 After the process has finished, you're all set. apt-get Ubuntu is the most popular desktop release version of Linux package, you should create a new folder in the src directory, with the notable exception of main, for which main folder creation is optional. Folder names are usually the same as the package that you are

Part III will give you an overview of Nim’s standard library, which contains topics to cover. So, for now, we will leave out the following: the installation of the compiler, the process of installing and using text editors or IDEs with special Nim support, the use of Nim package managers
