During QCon New York 2013, Rich Hickey gave a talk on functional databases. Hickey is well known for creating the Clojure programming language and is currently developing Datomic, which is a functional database. During his talk, Hickey argued that the useful properties of functional languages: data as values and pure functions, are just as useful in the context of databases.
Creating a simple immutable class in C# is easy, but eventually you’ll want to create deep graphs that, for efficiencies sake, should be created via a builder. Or perhaps you want to make non-destructive updates by creating methods. Building out all these builders and methods can be quite tedious and thus error prone. Andrew L Arnott offers a solution that relies on T4 based code generators.
Since we last reported on Immutable Collections in January, the API has evolved and a lot more has been revealed about the inner workings.
The newley released Erlang/OTP R16B brings several performance enhancements among its new features. Code modules can now be loaded in a non-blocking manner, networking code for ports has been improved, and VM processes have been parallelized.
Opscode released Chef 11 early this month with enhancements to its scalability to meet the demands of hyperscale web operations. Opscode rewrote the entire server core API in Erlang and at the same time kept it backward compatible. Opscode renamed the core server API "Erchef" to complement the rewrite in Erlang.
Damien Katz, Couchbase, believes that C is still a great language for back-end programming, while other developers argue that C has too many flaws, supporting C++ or Java, while others like neither.
ZeroTurnaround, the vendor behind the popular JRebel and LiveRebel JVM plugins, which accelerate the Java development cycle and automate app deployments to live environments without downtime, have announced a new research and content organisation called Rebel Labs. The organisation will, they claim, offer free, vendor-neutral technical resources for the Java community.
One of the most common misunderstandings in .NET development is the idea that variables of type IEnumerable or ReadOnlyCollection are thread-safe. In order to offer truly thread-safe collections for scenarios where you would be tempted to use IEnumerable or ReadOnlyCollection, Microsoft’s Base Class Library (BCL) team is offering a preview of a new set of immutable collections.
JetBrains has announced IntelliJ IDEA 12 having a better compiler, support for Java 8, an Android UI Designer, a new look, better Spring and Play 2.0 support, and a large number of enhancements across supported languages and frameworks.
InfoQ's research initiative continues with an 12th question: "What's Your Next JVM Language?". This is a new service we hope will provide you with up-to-date & bias-free community-based insight into trends & behaviors that affect enterprise software development. Unlike traditional vendor/analyst-based research, our research is based on answers provided by YOU.
Twitter's infamous Fail Whale was absent on US presidential election day, even as Twitter's servers were handling a serge of 327,452 "tweets" per minute. The firm was able to handle this level of traffic thanks in part to a gradual shift away from Ruby to Java and Scala
Atmosphere 1.0 is a new Java/Scala/Groovy framework that attempts to abstract asynchronous communication between the web browser and the application server. It transparently supports Web Sockets, HTML5 Server Side events and other application server specific solutions when available, with long polling as a fallback.
