InfoQ’s Robert Bazinet and Matthew Bass had the opportunity recently to talk with Jeremy McAnally about his new book, Ruby in Practice. Jeremy gives readers insight about the book but goes into detail about Ruby’s use in the enterprise.
Aaron Patterson has a solution for native Windows RubyGems that support both Ruby 1.8 and 1.9 at the same time: fat binary gems. Is It JRuby.com tracks JRuby compatibility for popular Gems; and some new RubyGems plugins emerged.
This interview talks about David A. Black’s new book, The Well-Grounded Rubyist, and his views on learning Ruby and making the transition from Ruby 1.8.6 to 1.9.1.
New patches by Joe Damato improve the efficiency of Ruby 1.8.x's green threads with heap stacks: instead of copying the entire stack at every context switch, the patches actually switch between different stacks. Ryan Davis released zenprofile and event_hook for efficient profiling. Also: work on a MacRuby Ahead of Time compiler using LLVM has started.
Dmitry Jemerov is the lead developer of the RubyMine IDE project at JetBrains. RubyMine is the new integrated development environment from JetBrains focusing on helping Ruby and Ruby on Rails developers be more productive and efficient programmers.
JRuby 1.3 will allow to reduce startup times in some situations using Nailgun. Nokogiri, a popular XML library, now runs on the latest JRuby thanks to ruby-ffi. Finally: Ruby 1.9.1-p129 is a new release that fixes a few bugs and security issues.
When it comes to performance, Ruby 1.9.1 seems to clearly beat it's predecessor, as a new real world benchmark shows. There are other ways, though, to avoid inefficiencies in 1.8.x, by knowing how the GC works or when to disable pthreads. Also: Viktor Hokstad's been busy writing a Ruby compiler from scratch.
RiCal is an implementation of RFC2445, better known as the iCalendar format. We talked to its creator Rick DeNatale to learn why Ruby needed a new library for parsing and generating the iCalendar format.
James Edward Gray II wrote a series of posts on character encoding in Ruby, providing various tricks and detailed explanations to make you ready for Ruby 1.9.
CrossTwine aims to improve the performance of MRI, 1.9.1, and Python. Unlike new Ruby VMs, the CrossTwine Linker allows to improve efficiency of the existing interpreters and VMs, while keeping their complete feature set. The company plans to offer services to use the CrossTwine Linker technology to speed up specific applications.
JetBrains, the developers of IntelliJ IDEA and ReSharper among others, released its first foray into the Ruby space with RubyMine 1.0 – an IDE for Ruby and Ruby on Rails development.
The current Ruby 1.9.1 doesn't have the required features to allow ParseTree's runtime features to work - which means some libraries that depend on those features won't work. Examples are Merb's action arguments or heckle. We take a look at the state of ParseTree - and how ruby_parser is a possible way out.
The first results of performance work on the next version of MacRuby are now available in an experimental branch. A new VM based on LLVM is used and already shows significant speed improvements over earlier MacRuby versions.
Ruby 1.9 adoption hasn't made much progress yet, the biggest problem being Gems that don't work with Ruby 1.9. "Ruby 1.9 Or Bust" is a new project that aims to increase the 1.9 compatibility for popular Gems.
Wee is a web framework similar to Seaside that uses continuations and provides reusable UI components. With Ruby 1.9, continuations stopped leaking memory and can therefore be used safely in a production environment.
