• async/remote work

• used DCI in production 3.years.ago

OOP vs FP

Use cases!

DCI

• Data

• Context

• Interaction

The mental model

objects

function

Focus on runtime interaction

Examples

• Gaming platform

• Meetup context

• Account example

Lessons from production

• Fewer objects

• More roles

• Use-cases == awesome

• great for testing (at use-case level)

• limitations of Ruby (unable to unextend)

Cope vs Uncle Bob on TDD

Marvin is a programming language that was designed with DCI in mind. It builds heavily on C#.

The first versions of Marvin can be seen as extensions to C# where versions in the road map will most likely reshape some of the fundamentals

to provide even better support for DCI

Code examples

Is it of practical use?

DCI as inspiration

How would it look as DCI?

Thanks!
