Clojure has a new core library, clojure.spec, that aims to provide a standard and integrated system for the specification and testing of data and functions. Besides making it possible to automatically validate Clojure code, the new specification system can be used for a number of tasks such as generative testing, error reporting, and destructuring.
R. Kent Dybvig, professor emeritus of Computer Science at Indiana University, now with Cisco, has recently open sourced version 9.4 of his formerly commercial Scheme compiler Chez Scheme.
Racket, a multi-paradigm programming language belonging to the Lisp/Scheme family, has reached version 6.5, writes Ryan Culpepper on Racket blog. The new version adds several new features, including improvements to typed/untyped code interaction, faster iteration on hash tables and sets, and more.
JetBrains has released IntelliJ IDEA 2016.1, the latest version of their most popular IDE. The new version seems to have the polyglot developer in mind, with multiple enhancements over a variety of languages and technologies; however, the most noticeable changes are aimed at Java, particularly at helping developers take full advantage of Java 8.
After 8 years of development, Lisp Flavoured Erlang (LFE) has reached version 1.0, bringing stable support for Lisp programming on the Erlang virtual machine (BEAM). LFE was created by Robert Virding, one of the initial developers of Erlang. InfoQ has spoken with Duncan McGreggor, current maintainer of LFE.
Jinq, a library to provide a DSL for database queries, has been made available for Java and Scala. The work is inspired by .NET's LINQ, and aims at enabling easy-to-write queries with support for type safety. As commented by Ming-Yee Iu, creator of the tool, work on Jinq started in 2006 under project name Queryll; however, the adoption of lambdas in Java 8 is what has realised its full potential.
Last week, the Scala Center was created as a not-for-profit foundation, along with a list of financial backers, to improve the ongoing development of Scala and provide training courses based around the Scala language.
The company formerly known as Typesafe, inventors of the Scala programming language, has completed their renaming and is now known as Lightbend. Typesafe announced their plans to rename last May, stating at that time that it was expected to be a two month process.

Racket, a multi-paradigm programming language belonging to the Lisp/Scheme family, has reached version 6.4, PLT announced. The new version adds several new features, including an incremental garbage collector (GC), and fixes a vulnerability in the web server.
San Francisco-based programmer Edgar Aroutiounian has recently created a package for OCamliOS, an OCaml cross-compiler for iOS recently made available by Jeffrey A. Scofield that should eventually be merged into the official OCaml compiler. InfoQ has spoken with Aroutiounian.
Architecting a scalable and dynamic system without caching is explained by Peter Morgan, head of engineering for the sports betting company William Hill. The values of the bets on sporting events change constantly. No data can be cached; all system values must be current. Distributed Erlang processes model domain objects which instantly recalculate system values based on data streams from Kafka.
José Valim has announced version 1.2 of the dynamic, functional Programming language Elixir. Valim, creator of Elixir, says the release "brings enhancements, bug fixes, performance improvements and more," noting that it requires at least Erlang 18+.
