Hackday Projects

Hack Day on Day 2 of the conference features community activities designed to connect fellow Rails developers and open source leaders in an environment that fosters collaboration and discussion. Choose between the Pitch Party, Birds of a Feather or contributing to open source projects.

Pitch Party

Bring your own ideas to the Pitch Party for a more traditional “build-it-quick” Hack Day. Collect a team of fellow attendees to take your vision from Hello World to MVP.

Birds of a Feather

Whether you’re looking to chat about new Rails technologies, seek career advice, or determine the best ramen spot in Detroit, Birds of a Feather empowers discussions around attendee-curated topics. Bring your own topic, or join an existing group for dynamic, informal conversations.

Open Source Projects

Work side-by-side with notable maintainers on popular projects and pair with experienced open source contributors to make their first pull requests to Rails. We’ve got an exciting lineup of maintainers joining us from Rails Core, RubyGems, Paper Trail, Nokogiri, Noticed, Rails-LSP, Thoughtbot and more!

Packs And Code Ownership

Packs provides an extensible packaging system to help modularize Ruby applications. `bin/packs` makes using packs easier. A `pack` (short for `package`) is a folder of Ruby code with a `package.yml` at the root that is intended to represent a well-modularized domain. Code_ownership helps engineering teams declare ownership of code. This gem works best in large, usually monolithic code bases where many teams work together.
