ECC - Fun Writing Compilers
Joe Armstrong presents ECC, an optimizing compiler running on LLVM for writing C compilers for unusual architectures, for implementing DSLs and for experiments with JIT compilation.

A document has appeared on the Clang website describing requirements for Automatic Reference Counting in Objective-C. This provides a service, akin to C++'s auto, which allows objects to automatically take part in the retain/release/autorelease cycle without requiring the user to do anything explicitly about it.
Unladen Swallow was an attempt to bring LLVM optimisations to the CPython runtime, but hasn't seen significant activity for the last year. Now, a Unladen swallow retrospective confirms that the project is defunct and is no longer being developed. What happened?
Apple has released iOS 4.3, the latest version of its operating system for mobile devices. This is available for iPhone (4 and 3GS), iPod Touch (3rd and 4th generation) as well as iPad and iPad 2 devices, as well as Xcode 4 which includes the LLVM 2.0 and LLDB 1.0 toolchains.
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.

The LLVM team yesterday released LLVM 2.8, the low-level virtual machine infrastructure that includes a next-generation C/C++ compiler, optimiser, and run-time. In addition, the LLVM also sports a VMKit for CLR and JVM runtime and is used in tools as diverse as MacRuby and Python's Unladen Swallow. Additionally, the recently-released Mono 2.8 has a mono-llvm runtime. So what's new in LLVM 2.8?
Rubinius has just released their first candidate for 1.0, bringing Ruby 1.8 compatibility and near speed parity. InfoQ talked to Evan Phoenix about what it took to get here and whether Rubinius will run Rails.
The first beta of MacRuby 0.5 is available, complete with a new VM, JIT and AOT - and without the GIL. InfoQ talked to the MacRuby core team about the state of MacRuby and whether there'll be a way to write Ruby apps for the iPhone using MacRuby.
