In this presentation from the JVM Languages Summit 2008, Mads Torgersen discusses LINQ, declarative programming and metaprogramming in C#, examples of LINQ syntax and usage, lazy evaluation of LINQ queries, extension methods, lambda expressions, LINQ-to-SQL, LINQ expressions and metaprogramming, expression trees, how the .Net Dynamic Language Runtime (DLR) works, PLINQ, and the future of the DLR.
Clojure, a LISP-style language for the JVM, is gaining interest quickly. One of the reasons is definitely its approach to concurrency which builds on Software Transactional Memory (STM). We talked to Stuart Halloway who's writing the first book on Clojure for the Pragmatic Programmers.
Meta Programming System (MPS), a new Language Oriented Programming tool from JetBrains, allows the developers to extend programming languages as well as create Domain Specific Languages (DSLs) for enterprise applications. JetBrains development team recently announced the release of beta version of MPS software.
Custom annotations are a great way to add common reusable behavior to Java applications. John Heintz from New Aspects discussed at the recent No Fluff Just Stuff (NFJS) Java Symposium, the design techniques for adding behavior to Java Annotations.
Model-driven software development no longer belongs to the fringes of the industry but is being applied in more and more software projects with great success. In this article we would like to pass on, based on the experiences we have gathered in the past few years, our contribution to its best practices.

Aaron Erickson introduces his new LINQ extension Indexes for Objects (i4o). Indexes for Objects allows for fast lookup against in-memory collections while retaining the LINQ syntax and semantics. He also discusses how expression trees interact with LINQ and how they can be leveraged in other scenarios.
Giles Bowkett captures the heart and soul of the RubyFringe conference as he demonstrates his revolutionary Archaeopteryx MIDI generator. He delivers an eloquent, highly politicized call to action in a career-defining presentation that is raucously hilarious yet unnerving in its practicality.
Jay Fields presents his concept of Business Natural Languages (BNL). BNLs are a type of Domain Specific Language, designed to be readable by any subject matter expert, which allows to create maintainable specifications and documentation. The example language is shown using Ruby.
Ryan Davis, known as "zenspider", is one of the highest-profile Rubyists in the world, and arguably one of the most influential ones. He is the author of a number of valuable Ruby open-source tools, including RubyInline and ZenTest. In this exclusive InfoQ interview, Ryan gives us a glimpse into how he has been pushing the envelope of what's possible with the Ruby language and runtime since 2000.
