Hello all, ...
My name is Ofer Ron, and I'm a senior data scientist at LivePerson.
Scala's collections library is a very good example of the programming maxim of Don't Repeat Yourself, or DRY. Using Scala's strong type system and orthogonal design principles, it enables code reuse between different collection types, while keeping the API frictionless.
In my talk, which follows the paper "Fighting Bit Rot with Types" (http://lampwww.epfl.ch/~odersky/papers/fsttcs2009.pdf) by the library designers, I demonstrated the principles behind the design, and the type system tricks which enable them.
