A stable release of the Ruby 1.9 series has now been around for a few months, but most developers are still using Ruby 1.8. Why is this? Ruby 1.9 is faster and uses less memory than 1.8; it also has Continuations that don't leak memory, just to name a few of the numerous advantages.
Antonio Cangiano, known for his Great Ruby Shootouts, has an explanation why so few have switched:
Some developers wrongly believe that Ruby 1.9 is just one intermediary step to Ruby 2.0, and as such it’s not meant to be used in production. Better communication could have avoided this common misconception. More importantly though, developers are not using Ruby 1.9 because there are very few libraries that work with it.
InfoQ recently reported on Ruby 1.9.1 library compatibility. Cangiano even sees a positive aspect in the 1.9 upgrading activity:
This switch to Ruby 1.9.1 can also act as a reset button when it comes to getting rid of many of the old, unmaintained, half-assed attempts from N years ago. Porting to Ruby 1.9.1 could act as a rough, implicit line of distinction between active and inactive projects.
While Cangiano tries to motivate projects and the community to put more effort into the 1.9 upgrade, Rob Kaufman has an interesting idea:
What if instead of trying to make every project maintainer learn all the tricks and skills needed to convert a piece of code to 1.9, we put up a little money to get one expert to work on converting gems over. Someone to work with maintainers to get their gems up to date. Someone who would gain practice as he converts gem after gem and who would dedicate real hours to making this conversion done.
Kaufman offers himself for that position and tries to raise money to finance the project, something Gregory Brown did for his work on the PDF library Prawn. Several approaches are possible, one could start with the most downloaded Gems from Ruby Forge, starting with a framework like Rails or Merb and its plug-ins or based on the reports on Is it Ruby 1.9. People can vote on the Ruby 1.9 Or Bust blog.
If you are interested in a faster Ruby 1.9 adoption, the Ruby 1.9 Or Bust project can be supported via Pledgie.

Brian Marick takes us through a quick tour of the most important values and challenges to adopting Agile successfully (they aren't the typical challenges and values we hear in the community).
The line between development and architecture is tricky. Does it exist at all? Is an ivory tower actually needed? There's a balance in the middle, but how do you move from developer to architect?
The word 'authority' sometimes produces an allergic response in hard-line agilists. Freedom and authority – both are bad if misused and both are good if used in right spirit for a noble cause.
"Getting Started with Grails" brings you up to speed on this modern web framework. Companies as varied as LinkedIn, Wired, and Taco Bell are all using Grails. Are you ready to get started as well?
Those familiar with only ITIL V2 often scoff at the thought that ITIL could serve as a governance framework for SOA. With ITIL V3, the focus of the framework shifted towards service-orientation.
SpringSource CTO Adrian Colyer discusses AspectJ, SpringSource's dm Server and tc Server products, OSGi and Scrum.
Heroku's Adam Wiggins talks about Rails, Background Jobs, Add-Ons, Ruby, and how Heroku manages to work around Ruby's inefficiencies using Erlang and other languages.
For Grady Booch the foundation of a good architecture is patterns, SOA being just one of many patterns. In this Second Life presentation, Booch attempts to bring more clarity on what architecture is.
