CvRDTs are almost as general as they can be.

CvRDTs are (almost?) as general as they can be

What are you talking about, and why should I care?

Now that we live in the Big Data, Web 3.14159 era, lots of people want to build databases that are too big to fit on a single machine. But there's a problem in the form of the CAP theorem, which states that if your network ever partitions (a machine goes down, or part of the network loses its connection to the rest) then you can keep consistency (all machines return the same answer to

Scaladays 2014 slides

As compiled by Kevin Wright a.k.a @thecoda

(executive producer of the movie, and I didn't even know it... clever huh?)

please, please, please - If you know of any slides/code/whatever not on here, then ping me on twitter or comment this Gist!

This gist will be updated as and when I find new information. So it's probably best not to fork it, or you'll miss the updates!

Enterprise Scala

Enterprise Scala

A guide to writing high-performance, robust, Enterprise-grade Scala applications.

Scala is a new language for the JVM that is rapidly spreading beyond tech companies like Twitter, Netflix, and LinkedIn, and into large Enterprises. Engineering teams in companies of all types and sizes are turning to Scala for its strong type system, its extensive ecosystem (Scalaz, Shapeless, Spire), and its seamless interoperability with legacy Java code bases.

While there are many books geared at introducing developers to the Scala programming language, none specifically address the question of what it means to write idiomatic Scala in today’s modern Enterprise. As a large, complex language with many advanced features, there are many ways to write Scala apps, and not all of them were created equal.

Enterprise Scala is the first book to systematize decades of real world, production experience writing large-scale, Enterprise-grade systems in Scala. The result is a comprehensive overview of what idioma
