Programming Languages: More Powerful with Less Freedom?
In quest for more power, languages are often grown with new features. While it provides programmer with more freedom, does this actually achieve more power? Reg Braithwaite believes that this is not necessarily true and argues that it is possible to render language more powerful yet limiting options offered to programmers.

Debate about Testing and Recoverability: Object Oriented vs. Functional Programming Languages
In his latest blog post, Michael Feathers argued that object oriented programming languages offer some built-in features that facilitate testing and are therefore more recovery friendly than functional languages. Proponents of functional languages expressed strong disagreement with this statement, which provoked a very passionate debate in the blog community.

Rush - OOP shell in Ruby
Rush is a new OOP shell written in Ruby. Unlike shells like bash, Rush has commands interacting with objects instead of strings, which allows to use regular Ruby constructs to iterate over files and other objects.

Interview: CORBA Guru Steve Vinoski on REST, Web Services, and Erlang
In a new interview, recorded at QCon San Francisco 2007, CORBA Guru Steve Vinoski talks to Stefan Tilkov about his appreciation for REST, occasions when he would still use CORBA and the role of description languages for distributed systems. Other topics covered include the benefits of knowing many programming languages, and the usefulness of of Erlang to build distributed systems.

Ruby 1.9 with Symbol#to_proc and (soon) curried Procs
Ruby 1.9 added the to_proc feature to Symbol, which allows for a very succinct way to create Procs that just call one method. Also: a recent development version of 1.9 added currying to Ruby. We look at how these features work and what they can be used for.

Presentation: Ruby and the Art of Domain Specific Languages
Rich Kilmer gives an introduction to the art of creating Domain Specific Languages in Ruby. The presentation gives a basic introduction, but moves on to useful distinctions in DSL styles, such as implicit vs. explicit internal DSLs or declarative vs. imperative DSLs. A look at a long list of real world DSLs Rich has created rounds of the presentation.

Communicating Intent through Idiom and Paradigm Selection
What about using idioms and programming conventions as signals to achieve more readability and expressiveness? This is what Reg Braithwaite advocates for, suggesting that syntax or even paradigm choices can be a means to communicate the intent.

Using ParseTree for LINQ-style queries and extracting metadata
Whether it's LISP macros or LINQ's expression trees - access to the AST of code is a powerful tool. We look at how ParseTree allows this in Ruby - and how it's being used in libraries like Ambition, Sequel and the web framework Merb.
