A Programming Model and Foundation for Lineage-Based Distributed Computation

The most successful systems for "big data'' processing have all adopted functional APIs. We present a new programming model we call function passing designed to provide a more principled substrate, or middleware, upon which to build data-centric distribute ...

Function Passing: A Model for Typed, Distributed Functional Programming

Heather Christine Klug, Philipp Haller, Jocelyn Boullier

The most successful systems for “big data” processing have all adopted functional APIs. We present a new programming model we call function passing designed to provide a more principled substrate on which to build data-centric distributed systems. A key id ...

Distributed Programming via Safe Closure Passing

Heather Christine Klug, Philipp Haller

Programming systems incorporating aspects of functional programming, e.g., higher-order func- tions, are becoming increasingly popular for large-scale distributed programming. New frameworks such as Apache Spark leverage functional techniques to provide hi ...

Self-Assembly: Lightweight Language Extension and Datatype Generic Programming, All-in-One!

Heather Christine Klug, Philipp Haller

In this paper we show a general mechanism, called self-assembly, for lightweight language extensions (LLEs). LLEs allow users to define generic operations or properties that operate over a large class of types. With LLEs it is possible, for example, for us ...

Spores: A Type-Based Foundation for Closures in the Age of Concurrency and Distribution

Martin Odersky, Heather Christine Klug, Philipp Haller

Functional programming (FP) is regularly touted as the way forward for bringing parallel, concurrent, and distributed programming to the mainstream. The popularity of the rationale behind this viewpoint (immutable data transformed by function application) ...

Functional Programming For All! Scaling a MOOC for Students and Professionals Alike

Martin Odersky, Heather Christine Klug, Philipp Haller, Lukas Rytz

Massive open online courses (MOOCs) have launched a scale shift in higher education, with several individual MOOCs now boasting tens or hundreds of thousands of participants worldwide. Our MOOC on the principles of functional programming has more than 100, ...

Containers and Aggregates, Mutators and Isolates for Reactive Programming

Martin Odersky, Philipp Haller, Aleksandar Prokopec

Many programs have an inherently reactive nature imposed by the functional dependencies between their data and external events. Classically, these dependencies are dealt with using callbacks. Reactive programming with first-class reactive values is a parad ...

RAY: Integrating Rx and Async for Direct-Style Reactive Streams

Heather Christine Klug, Philipp Haller

Languages like F#, C#, and recently also Scala, provide “async” extensions which aim to make asynchronous programming easier by avoiding an inversion of control that is inherent in traditional callback-based programming models (for the purpose of this pape ...

Scala-Virtualized: Linguistic Reuse for Deep Embeddings

Martin Odersky, Tiark Rompf, Philipp Haller, Nada Amin

Scala-Virtualized extends the Scala language to better support hosting embedded DSLs. Scala is an expressive language that provides a flexible syntax, type-level computation using implicits, and other features that facilitate the development of em- bedded ...
