Jon Pretty
Jon has been having fun riding the bleeding edge of Scala for over a decade, and he's not finished yet.
While he's not travelling the world attending Scala conferences, or organizing Scala World, Jon spends his time working on a variety of open-source Scala libraries, and providing professional Scala training services.

Impromptu: Using Dependent Types to Build a Better API for Async Call Graphs
Featuring Jon Pretty
Writing asynchronous code is often an uneasy fit for a language like Scala. While high-level constructs like Futures facilitate asynchronous programming, syntactic limitations often make blocking or the unchecked access of asynchronously-computed values more natural than the safer alternatives.

Writing your own compile-time checks for your favourite embedded DSL!
Featuring Jon Pretty
Interpolated strings, like the familiar
s"", provide a convenient way to embed external DSLs in Scala source, allowing you to construct a new value at runtime from a string literal, with Scala expressions substituted within it. But unless you are prepared to implement the interpolator... -

Exploiting Dependent Types for Safer, Faster Code
Featuring Jon Pretty
Scala's type system allows you to enforce compile-time constraints on your programs, and to take advantage of these constraints to help reason about your code. Yet you still frequently encounter situations where extracting a value from a map is not guaranteed to succeed, or mapping across a...

Demystifying Type Inference
Featuring Jon Pretty
Understanding type inference in Scala is often seen as a dark art. How does the compiler sometimes manage to conjure up exactly the correct type from an horrendous tangle of generic method calls, while at other times it draws a blank at something that seems plainly obvious to everyone else?

Batshit Crazy Algebra with Types
Featuring Jon Pretty
What would it mean to ""add"" or ""multiply"" types like Boolean and List[Int]? What interpretation could you possibly attribute to differentiating types, and what's this got to do with zippers? London Scala User Group will be joined by Jon Pretty who...

How to please everyone, all the time - lessons in Scala API design
Featuring Jon Pretty
How do you design a library which satisfies a dozen different use cases? How can the same API be ideal for the rigour of a mission-critical production environment, yet still perfect for quick scripting in the REPL?
