About Ruby

Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.

Ruby was created as a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

He has often said that he is "trying to make Ruby natural, not simple," in a way that mirrors life.

Building on this, he adds: "Ruby is simple in appearance, but is very complex inside, just like our human body."

You can read more about the Ruby language on its site.

I loved the Ruby track

I loved the Ruby track (it is the only one I have finished so far). Solving over 80 different problems seems one of the most exciting ways to learn a language one barely knows. Improving my own solutions for readability and beauty rather than just passing the tests and performance taught me a little about Ruby and programming in general. I also liked comparing my solution to other ones - I could see the problem from other points of view.

Relaxed. Encouraging. Supportive.

Ruby launched my software development career, and I love its simple syntax and minimal amount of concepts. The Ruby community has also taught me so much that I can bring to whatever language I am using.

Ruby will always be dear to me because it lets you say what you need in the way that you want. I use Ruby at work.

Ruby is awesome. It's easy to learn, easy to read and yet so powerful. I've learned many programming languages and ruby will always be my favourite one. Besides the ruby community is super nice!

I started writing Ruby 4 years ago when I co-founded Workplace Arcade. I quickly fell in love with the language and have been using it ever since. I'm very passionate about mentoring and co-organize a local ruby meetup.
Fun. Challenging. Interesting
