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.

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.

Languages Come to Javascript VMs: CoffeeScript 1.0, StratifiedJS, C/C++ with Emscripten, Python

by Werner Schuster on  Dec 25, 2010 7

Javascript's ubiquity and increasingly fast VMs have made it an interesting runtime for languages. InfoQ looks at languages and tools that compile to Javascript: CoffeeScript 1.0, StratifiedJS, the Emscripten LLVM backend which brings C/C++ to Javascript, and more.

JDK7 Feature Slip

by Alex Blewitt on  Sep 10, 2010 12

In a post entitled Re-thinking JDK7, Mark Reinhold put forward a suggestion that certain previously planned elements of JDK7 be suspended until JDK8 in order to get the release out of the door sooner rather than later. What does the community think of this suggestion? Read on to find out.

Optional Parameters Are Gaining Ground in .NET

by Jonathan Allen on  Jul 06, 2010 6

Optional parameters have always been part of .NET, but with C# unwilling to support it, using them was generally considered taboo unless work with COM libraries. Now that C# 4 does support them, we are starting to see them used for a lot more than just legacy code. Other uses include interoperability with dynamic languages, immutable data structures, and various parts of ASP.NET MVC.

by Jonathan Allen on  May 13, 2010 3

Dana Groff has announced the end of Microsoft’s experiment with software transactional memory for the .NET Framework. Known as STM.NET, this research project was announced in 2008 as an alternative to explicit locks when dealing with concurrency issues.

Clojure 1.1 Adds Transients, Chunked Sequences for Efficiency

by Werner Schuster on  Dec 17, 2009

Clojure 1.1 RC1 is out and cuts the overhead of functional programming with a few new constructs: transients bring controlled mutability for persistent data structures; chunked sequences make lazy sequences more efficient. InfoQ takes a look at what makes these improvements work.

by Charles Humble on  Nov 25, 2009 4

Sun's Java SE team recently released the Milestone 5 build of JDK 7. This was expected to be a feature complete release of Java 7 but is some way short of that. InfoQ takes a look at what has been added and some of the major features still missing.
