We all know Ruby and Rails are great tools for startups and fast development of new applications. But did you know that the campus software of the Technical University in Vienna is powered by a >380.000 LOC Ruby on Rails application that was started in 2011 and is actively developed and maintained by a small, dedicated team of Ruby developers ever since?

A senior Ruby developer from this team shares patterns and solutions distilled from more than 10 years of his work on this project, for example how the team gradually migrated the Rails application from Rails 2.3 to Rails 6.1 and Hotwire Turbo, how a big amount of data is kept in sync between the rails applications and many other applications at the university, how to make big changes to the code base without upsetting all users, and much more.
