Who am I

  • I am self-employed and a large chunck of my work is teaching people how to improve their programming life. This included teaching them how to use git and how to use it properly. How to write automated tests, how to setup a CI system. It includs also teaching programming langiages. Perl when that was the popular language. Then I Python, and now it might be Rust. Is it?

Why learn a programming language?

  • It is fun to learn a new language.

  • It is fun to solve problems. A programming language is like a maze. You need to find out the rules and you need to find your way through the maze.

  • Learning a programming takes time

Some peole go deep and only then start to write. Some people try fail and improve.

Learn by reading

  • Reading the documentation is borimg
  • Even reading tutorials is frustrating.
  • I'd like to get my hands dirty
  • F around and find out

Learning programming

  • Install from Rustup

  • Reading a tutorial

  • Reading the official documentation

  • Watching videos

  • Writing small examples

  • Writing a translation guide from another programming language you already know.

  • Course

  • Writing a project

  • Reading the source code of open source projects

  • Contributing to open source projects

  • Learn concepts in context

  • Use real-world examples (try to implement them)

Web based runner or local environment?

Getting feedback

One of the most important thing in learning is getting feedback

  • The compiler - errors
  • You get the results
  • Writing and running tests

Platforms to get feedback

  • Rustlings
  • Exercism
  • Asking on forums

Rust Toolchain

Rust has a really nice tool chain with built in code formatter and linter.

Example

  • Some crates, such as Serde have examples listed on their pages.
  • Other crates have examples in their git repository.
