Blogo is a Mac / OS X blogging client developed by Brainjuice - the business name of Benjamin Jackson and Ivan Neto, Rio based Ruby developers and Web designers - and born out of their frustration with existing commercial blog editors.

Vidar Hokstad is the writer behind the fine Writing a Compiler in Ruby series, but he's taken a break to explain the structure and semantics of the Ruby object model. It's a fine walkthrough.
