A whole batch of new Ruby VM releases is available. MacRuby 0.8 fixes bugs and begins the path to 1.0. Rubinius 1.2 improves memory efficiency and the debugger. MRI received new patch levels: 1.8.7-p330 and 1.9.2-p136, the first big bug fix update to 1.9.2.
John Blanco published a comparison between the iPhone and Android Development Environment. Even though he favors Java as a programming language, he believes that Xcode and the iPhone simulators are vastly superior to the tools provided by Google. Do you agree?
Rubinius 1.1 is out, with JIT and performance improvements, more powerful debugging and profiling capabilities. Also: the GIL algorithm gets an overhaul in 1.1 - but it'll soon be history. In the Hydra branch of the Rubinius project, a GIL-less Rubinius is being groomed, soon to join JRuby, IronRuby and MacRuby in the GIL-less VM crowd. InfoQ caught up with Evan Phoenix about the Hydra branch.
MacRuby 0.6 is available now, bringing debugging and vastly improved Grand Central Dispatch (GCD) support. A lot of the core functionality has been overhauled, such as a new String implementation and a new thread-safe Regex library which replaces Oniguruma. MacRuby's now considered stable for Cocoa development.
InfoQ reported a Flash and AIR debugger Arthropod earlier this year. De MonsterDebugger is another debugger launched this year for Flash, Flex and AIR application development.
A first incarnation of ruby-debug support on 1.9 is now available. Ruby switcher makes it easy to run different Ruby versions in parallel. Also: MacRuby's experimental branch was merged into MacRuby Trunk.
Debugging tools are essential for software development in any computer language and runtime environment. Adobe Flash platform-based rich Internet application (RIA) development, either in Flex or AIR, is no exception. While the Flex/AIR is maturing, more debugging tools are emerging. Arthropod is one of them.
The Ruby implementation Rubinius has attracted a lot of interest. After the project completed a major rewrite of its VM, we caught up with Brian Ford, Rubinius team member, to talk about the state of the project.
Kent Beck, renowned co-father of XP, TDD, and JUnit itself, tells a story about tracking down a defect in a new JUnit feature, JUnitMax, with unit tests instead of a debugger. He explains a method shown to him by current JUnit lead developer, David Saff, where a high level unit test is recursively inlined until a super concise test is created down at the very root of the defect.
Sascha Balkau has recently released Alcon 3, an alternative open source debugging tool for ActionScript 2 and ActionScript 3. InfoQ spoke with Balkau to discuss how Alcon 3 fits in ActionScript-based rich Internet Application development.
The success of Microsoft Silverlight, as seen in the recent Beijing Olympics, shows the capabilities of the technology and is attracting more developers. The addition of end-users and developers using Silverlight will also drive more tool development and one such useful tool is Silverlight Spy by First Floor.
Some recent changes on the JRuby trunk improve Java Integration, which allows JRuby to interact with pure Java code faster and more conveniently. Also: Ruby code compiled with JRuby's (JIT) compiler can now make use of the JVMs debugging capabilities using JSR-45 (Debugging Support for Other Languages).
