Bio

Alissa Pajer began her functional programming career as a Scala engineer at Precog. She worked there for two years until Precog was acquired by RichRelevance, her current employer. Before her coding days, she studied pure mathematics, earning a Bachelors from Carleton College and a Masters from the University of Colorado. She spends her non-computer time hiking, running, swimming, and cycling.

About the conference

CRAFT is about software craftsmanship, which tools, methods, practices should be part of the toolbox of a modern developer and company, and it is a compass on new technologies, trends.

    Is the correct term for this rather "Parametric polymorphism"?

    The commonly accepted term is "Parametric polymorphism" and indeed this was used by John C. Reynolds himself (see "Types, Abstraction and Parametric Polymorphism").

    Would love to see the sequel (covering monads in the same enthusiastic & practical style would be great)!
    Martin :-)
    PS: Small typo at 6:15? :: Shouldn't "// f(big(a))" be "// big(f(a))" ?

    Thanks!

    You're right that is a typo. I think was going back and forth between `compose` and `andThen` when writing the slides :)

    In the talk did I call it "Polymetric polymorphism"? Oops! :) Thanks for the correction.

    Years ago, I tried to get through Benjamin Pierce's "Basic Category Theory for Computer Scientists", but my math background was too weak to grok the nomenclature. This presentation is a bit like finding a Rosetta Stone. Thanks so much -- I would love to see more.

    Yes, I learned Cathegory theory decades ago and I love the idea that it could be put to use. This is exciting.
