FP Complete has launched Haskell Center, their new Haskell IDE and application server. The IDE is browser based, and together with their application server, should make it much easier to create and run web based Haskell programs.
Reactive programming (RP) is based on data flows and the propagation of change, with the underlying execution model of a programming language automatically propagating changes through the data flow. With the popularity of event-driven, scalable, and interactive architectures both on the server and the client, the concept of “reactiveness” is increasingly gaining attention.
For many of us Twitter has become an essential communications utility. Since experiencing scalability problems in 2010, Twitter has moved to a loosely coupled service oriented architecture based on the JVM, allowing it new levels of scalability and feature agility. Twitter engineering recently reported a new record throughput and took time out to describe their new architecture.
In the newest drop of Immutable Collections for .NET we get ImmutableArray
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.
