Engine Yard, a software developer of cloud deployment and open source tools for Ruby on Rails applications, last week released an open source framework for building fast, high-performance Ruby applications. Called “Merb,” the programming tool is similar to Ruby on Rails. Merb is an MVC framework. It features a modular — rather than monolithic — architecture with minimal, clean core code that’s simple, organized and easy to extend, according to Engine Yard. “We built Merb as a new way to do things faster,” Yehuda Katz, maintainer of the Merb Project, told LinuxInsider.
