I’ve paused watching at the 9th minute when he starts showing that it’s not trivial to represent a DB generated id… and I’m wondering wether the whole problem goes away by just using application generated UUIDs? Or by having different classes for writing a new Prof and for reading a persisted one?
Is there a way to do the same if the data structure looks more like this: case class ProfF[A](name: String, students: List[Student]) case class Student(name: String, year: Int)
Timm Fix is the monad for the recursive data pattern. You data structure is not recursive so you cannot use Fix. You can use something simpler like Functor.
functional programming is nice and I use everyday but there is a limit. not every problem can be solved using functional stuff. i really hate it when some idiot trying to prove that functional programming is the silver bullet and turns everything into functional just for the sake of being functional while loosing readability and lacks common sense.
One of the best talks about Free, Cofree and Fix. Thanks Rob Norris. Inspirational for many developers.
I attended Scala Up North in Montreal last year, and this dude was the only one who impressed me.
One of the best talks I've ever seen
An awesome presenter. Every time.
Very nice flow of concepts!

Awesome!
The demise of Scala began with these guys.
AMazing.... Want to go back to scala again.

I've seen this like 5 times and I still can't grasp what he says from min 8 on
How much change was in his pocket?
Welcome to the dark side of the force with frameworks like matryoshka and shapeless :D
