Dave Thomas, Start writing Ruby (stop using classes). San Francisco Ruby Conference 2025.

David Thomas is a legend of the Ruby community and the Agile software development movement, an author of numerous books on Ruby and Rails, and the founder of the Pragmatic Bookshelf. In this talk, he argues that developers are writing Ruby code the wrong way. They use classes as the unit of design when they don't need and shouldn't rely on them. They also treat design patterns as recipes, which makes them largely irrelevant. Finally, developers create arcane project structures and convoluted deployment systems when it's not necessary.
