Type-Driven Development in Practice: Cats and Akka HTTP

Featuring Matt Roberts

Type-driven development is a programming style where you write types first and use them to guide the definition of functions in your program. Scala is particularly well suited to it because of its powerful type system. Cats lets you take Scala and type-driven development even further by...

Validating Big Data Jobs - Stopping Failures before Production (w/ Spark, BEAM, & friends!)

Featuring Holden Karau

As big data jobs move from the proof-of-concept phase into powering real production services, you will need to consider what will happen when everything eventually goes wrong (such as recommending inappropriate products or other decisions taken on bad data).

Keynote: Conveying the Power of Abstraction

Featuring Dr Eugenia Cheng

Abstract mathematics is sometimes thought of being very far removed from real life, perhaps something that people think about with their head in the clouds as opposed to the sort of applied maths and science do when people are thinking about "reality". And yet, many of you who work in...

Monad I Love You Now Get Out of My Type System

Featuring Gjeta Gjyshinca and James Belsey

Functional programming has features such as presumed immutability and a declarative nature. With the rise of multicore machines and the growth in multi-threaded programming, it's natural for functional programming to increase in prominence. However non-functional programming languages and...

Connecting the Dots With (Distributed) Tracing

Featuring Petra Bierleutgeb

In microservice-oriented, asynchronous and often event-driven systems, looking at traditional log files only gives a glimpse of the whole story. In such systems, and even within a single service, tracing and correlated logs are important tools to maintain the ability to comprehend logical flows...

Meetings With Remarkable Trees

Featuring Bodil Stokke

Everybody knows the classic cons list. Clojeurs brag about their bitmapped vector tries. Haskell weenies took it up a notch with their impossible finger trees. Rustaceans turned back the clock and gave us simple arrays again.

A Fistful of Functors

Featuring Itamar Ravid

Functors show up everywhere in our day-to-day programming. They're so common, we take them for granted – especially in typed functional programming. Besides being common, they're incredibly useful for code reuse. However, functors have some lesser known variants: profunctors, bifunctors,...
