Scala Async: A New Way to Simplify Asynchronous Code

Scala Async makes it possible to “suspend” at arbitrary points in a block of regular Scala code, and to “resume” from that point later— all without blocking. This not only makes it possible to make concurrent code look sequential, it makes it possible to actually use even the most unfamiliar asynchronous libraries in a familiar blocking style.

On Pickles and Spores: Improving Scala's Support for Distributed Programming

This talk presents a new pickling framework designed for Scala with a few attractive properties: (1) using the framework requires little to no boilerplate, (2) using Scala's implicit parameters, users can add their own easily-swappable pickle format enabling users to persist to a number of formats, binary, JSON, or your own custom format, (3) using the type class pattern, users can provide their own custom picklers to override the default behavior of the pickling framework, (4) static, macro-based generation of picklers enables significant performance improvements.

Expanding eta-expansion: shapeless polymorphic function values meet macros

Polymorphic function values are one of the key abstractions in shapeless: they are crucial to enabling sequence-like operations such as map, flatMap and filter to be performed on HLists (data structures which combine the heterogeneous typing of tuples with list-like characteristics).

Miles Sabin

Spark Streaming is a new extension to the Spark cluster computing framework that enables high-speed, fault-tolerant stream processing through a high-level Scala API.

Deciphering Maya Hieroglyphic Writing with Scala

In particular, the research framework presented here makes extensive use of the facilities that Scala provides to build external Domain Specific Languages that epigraphers can use both to provide accurate transcriptions and transliterations of hieroglyphic texts, and to query the linguistic corpora for quantitative and qualitative analyses.

Designing for performance

Scala provides a wide variety of productivity- and correctness-enhancing features, but some of those come at the cost of performance. I will discuss how to design Scala applications to take maximal advantage of Scala's best features while still yielding Java-like performance--or better since you can spend your time thinking and optimizing instead of writing boilerplate!

One API to rule them all

Designing a REST API for multiple applications and devices is typically an exercise in trade-offs. A single API offers efficiency in terms of building and maintenance costs; specialised APIs, though tedious to build, can be optimised for each particular use-case, removing unnecessary computational overheads.
