Title
Description
http://www.rubyconf.org.au Whenever the stereotypical Ruby developer hears the words "statically-typed", they have one of two responses: they have flash-backs to their C++/Java days they prepare their memorized Alan Kay / Kent Beck quotes for battle. Now that stronger typing is coming to Ruby, maybe we need to calm down a little. This talk is not designed to persuade anyone to drop our beloved Ruby, but maybe we can learn some lessons from our stronger-typed friends to bring even greater happiness than before.

In the talk titled "You And Your Type[s] Aren't Welcome Here" presented by Andy Nicholson at RubyConf AU 2017, the speaker addresses the often controversial subject of type systems within the Ruby programming community. The primary aim of the presentation is not to convince Ruby developers to abandon their beloved language but rather to explore how adopting certain practices from statically-typed languages can enhance their coding experience and reduce errors. Key points discussed include: - **Emotional Reactions to Type Systems**: Nicholson begins with a light-hearted engagement, urging the audience to acknowledge their emotional responses to type systems. - **Defining Type Systems**: He explains what a type system is, citing Wikipedia to illustrate its purpose in preventing bugs through type definitions in code. He emphasizes that types can add metadata that enhances our code's robustness. - **Duck Typing in Ruby**: The speaker elaborates on Ruby's approach to types, primarily through duck typing, where the behavior of the object determines its type rather than explicit declarations. He highlights the practical implications and potential pitfalls of this approach. - **Error Handling and Clarity**: Through various coding examples, Nicholson shows how improved type handling can lead to better error messages and clearer code. He demonstrates a case where improper type usage results in confusing error messages and suggests that leveraging stronger typing practices can alleviate these issues. - **Code Execution and Result Types**: Nicholson proposes implementing a structure similar to result types found in other languages to manage errors more elegantly, a method taking inspiration from functional programming practices. - **Exploration of Other Languages**: The talk also touches on languages like Elixir and Crystal, encouraging Ruby developers to consider the benefits and insights these languages offer, especially regarding type safety and concurrency issues. - **Closing Thoughts**: He concludes by encouraging developers to think about how different language paradigms can inform their Ruby experience, sparking curiosity about making their code more enjoyable and manageable. Overall, Nicholson's presentation invites Ruby developers to consider the advantages of thinking about types, learning from other paradigms while maintaining their creativity and flexibility in coding.
