It is an object oriented, general purpose programming language that is very well suited for web development. It is dynamically typed and puts a big emphasis on code readability. I like the elegance of well written Ruby code and the powerful testing frameworks that exist for Ruby. ### Snippets #### Round time down to a given interval ``` FIFTEEN_MINUTES = 15 * 60 t = Time.new # 2020-05-15 08:46:58.156386 +0200 rounded_time = t - t.to_i % FIFTEEN_MINUTES # 2020-05-15 08:45:00.156386 +0200 ``` ### Libraries * [Sneakers](https://github.com/jondot/sneakers) - A fast background processing framework for Ruby and RabbitMQ * [RSpec](https://rspec.info/) - Behaviour Driven Development for Ruby.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://wiki.fruetel.net/software-engineering/ruby.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
