Yeah, this takes you up to almost 590 characters... internationalization is a bloody long word.

Internationalization (i18n) is a useful and marketable skill that even a
novice developer can learn, yet many experienced Rails developers have never
attempted it.

Much like testing, internationalization of a Rails application shouldn’t be an
afterthought. It can help save time and simplify a codebase, even if the
application is deployed in one language.

In this session we’ll cover the process of internationalizing a Rails
application, a handful of useful gems and services, and look at how the
process improves the codebase.
