Java Lambda Syntax based on C#, Scala

by Alex Blewitt on  Sep 09, 2011 5

A recent posting on the lambda-dev mailing list announced the conclusion that the Java Lambda syntax will be based on C# syntax, very similar to Scala's implementation that many are already familiar with: "It was better to choose something that has already been shown to work well in the two languages that are most like Java – C# and Scala – rather than to invent something new."

An Overview of the X++ Programming Language

by Jonathan Allen on  Aug 08, 2011 1

X++ is a 17 year old programming language with a syntax that meshes the structural and imperative features of Java with the set-based operations of SQL. It is primarily used within Dynamics AX, an enterprise resource planning platform. Originally a completely proprietary language, as of 2009 X++ can be compiled to .NET’s Intermediate Languages.

Interactive Extensions for LINQ to Objects

by Jonathan Allen on  Jul 28, 2011 3

Interactive Extensions (Ix) is a set of additional LINQ to Objects query operators based on the work done in the Reactive Extensions. A quick look through the API reveals a set of IEnumerable extension methods under the System.Linq namespace. While most developers already have many of these in their own utility libraries, having a standard implementation for these missing features would be useful.

ClojureScript Brings Clojure To The Browser via Javascript

by Werner Schuster on  Jul 26, 2011 2

Rich Hickey has announced ClojureScript, a version of Clojure that is compiled to Javascript code, which will bring the Clojure language to the browser and to the mobile space. InfoQ takes a look at the rationale for and implementation of ClojureScript.

An Introduction to D and Visual D

by Jonathan Allen on  May 24, 2011 2

D is a systems programming language from Digital Mars that focuses on “combining the power and high performance of C and C++ with the programmer productivity of modern languages like Ruby and Python.” While still being a statically typed language that compiles directly to native code, the syntax looks very much like Java or C# but it has some interesting advances.

Creating a new JVM language

by Alex Blewitt on  Apr 18, 2011 3

Creating a new JVM based language has recently hit the for with the news of the proposed Ceylon project. In fact, the JVM already has a diverse set of languages, both statically typed and dynamically typed. What does it take for a new language to hit the mark?

Ceylon JVM Language

by Alex Blewitt on  Apr 13, 2011 16

Gavin King, creator of Hibernate, gave a presentation at QCon Beijing on the Ceylon JVM language. Ceylon addresses some limitations of the Java programming language although the project is near the inception phase, with no compiler or IDE support. Since its existence leaked out over twitter, there has been a lot of speculation about the language; read on to find out more from Gavin King

Erlang Copied Scala's Actors & Erlang's VM is almost a Clone of the JVM

by Sadek Drobi on  Apr 01, 2011 8

Erlang Co-creators, Joe Armstrong and Robert Virding, admit that Erlang is heavily inspired by the Java world. In an interview at ErlangFactory 2011 SF, they reveal how Scala Actors had shaped their work in what they then called Erlang Processes. Moreover, they acknowledge the fact that Erlang's VM is barely a clone of the famous JVM.

Going Beyond the Standard: Continuations in Mono

by Jonathan Allen on  Mar 09, 2011

While Mono usually strives to follow the C# and Common Language Infrastructure specifications, it does occasionally go beyond them. While some features such as SIMD support are backwards-compatible with .NET, runtime supported continuations are exclusive to Mono.

SGen: Mono’s Generational Garbage Collector

by Jonathan Allen on  Jan 20, 2011 4

Mono had a dirty little secret. Until recently it used the portable but woefully inaccurate Boehm-Demers-Weiser conservative garbage collector. After two long years of work Mono is making the shift to a new generational garbage collector that is specific to the CLR and far more precise than anything they’ve had before.

The State of JRuby: 1.6 RC1, JSR 292 and NIO2 in Java 7, 1.9.2 Support

by Werner Schuster on  Jan 16, 2011

The first RC for JRuby 1.6 is out and brings improved Ruby 1.9.2 compatibility, experimental C extensions support, improved Windows support, Ruby Gems Maven support, performance and profiling improvements and more. InfoQ talked to JRuby's Charles Nutter about JRuby 1.6, the impact of Java 7 on JRuby, new language features in Ruby and much more.

Visual Basic is Losing Its Runtime Library

by Jonathan Allen on  Jan 13, 2011 3

The rather extensive runtime library used by Visual Basic and its compiler has been a major stumbling block for the language. Both the Windows Phone 7 and the XBox 360 don’t support the library, making clumsy workarounds necessary. With Visual Basic 10 SP 1, Microsoft once again tries to get it right.

Why Microsoft Believes that VB and C# Need an Asynchronous Syntax

by Jonathan Allen on  Jan 04, 2011 2

The new Async CPT for VB and C# looks like it may actually make it into the core language. But with all the emphasis on multi-core systems, why is Microsoft investing so heavily in syntax for designed specifically for making single-threaded asynchronous programming easier?

Follow-up: Razor with F# and Other Languages

by Jonathan Allen on  Jan 03, 2011

Last month Vladimir Kelman asked if it were possible to use F# with the new Razor view engine. After talking with Scott Guthrie and Marcin Dobosz we learned that it is possible, if you want to put in the effort to build all necessary plugins yourself.

MonoDevelop is the Third IDE for F#

by Jonathan Allen on  Dec 27, 2010

MonoDevelop has become the third IDE to support Microsoft’s F# language. With .NET support essentially dead on the Eclipse IDE and WebMatrix being targeted for causal developers, it is likely to be the last IDE to add support for it in the foreseeable future.
