SubScript, a way to extend common programming languages aimed to ease event handling and concurrency. Typical application areas are GUI controllers, text processing applications and discrete event simulations. SubScript is based on a mathematical concurrency theory named Algebra of Communicating Processes (ACP). ACP is a 30-year-old branch of mathematics, as solid as numeric algebra and as Boolean algebra. In fact, you can regard ACP as an extension to Boolean algebra with 'things that can happen'. These items are glued together with operations such alternative, sequential and parallel compositions. This way ACP combines the essence of grammar specification languages and notions of parallelism.

"Rust is a curly-brace, block-structured expression language. It visually resembles the C language family, but differs significantly in syntactic and semantic details. Its design is oriented toward concerns of "programming in the large", that is, of creating and maintaining boundaries - both abstract and operational - that preserve large-system integrity, availability and concurrency. It supports a mixture of imperative procedural, concurrent actor, object-oriented and pure functional styles. Rust also supports generic programming and metaprogramming, in both static and dynamic styles."

"A concurrent programming library combining monadic and streaming I/O in Scala."

ShareJS is an Operational Transform library for NodeJS & browsers. It lets you easily do live concurrent editing in your app.

"Titan is a scalable graph database optimized for storing and querying graphs containing hundreds of billions of vertices and edges distributed across a multi-machine cluster. Titan is a transactional database that can support thousands of concurrent users executing complex graph traversals."

"In this paper we propose the TurboXPath path processor, which accepts a language equivalent to a subset of the for-let-where constructs of XQuery over a single document. TurboXPath can be extended to provide full XQuery support or used to augment federated database engines for efficient handling of queries over XML data streams produced by external sources. Internally, TurboXPath uses a tree-shaped path expression with multiple outputs to drive the execution. The result of a query execution is a sequence of tuples of XML fragments matching the output nodes. Based on a streamed execution model, TurboXPath scales up to large documents and has limited memory consumption for increased concurrency"

Buen set de tests comparativos entre varias implementaciones de paralelismo local.

A programmer building an Internet-based application interacts with, on average, no less than a dozen technologies. These applications need nearly continuous operation: 24-7 availability in order to service hundreds to thousands of concurrent requests. Developers need the tools to manage that complexity and Monadic Design Patterns for the Web serves that need.

Muy lindo y accesible ejemplito para conocer Akka y sus posibilidades.
