A Gringo's Guide to Internationalization
Coming from a speaker who escaped a notion to "why would we need to translate?" this talk aims to show what actually goes into translating a website or app using Django's Internationalization tools. Covered will be an overview of batteries included, best practices and anti-patterns in using them, and some third party tools to help make your life escaping the myth of a Lingua Franca easier.
There's often a bubble in the English-speaking programming world that the entire internet runs on English. Our Top-level domains are shortened english words. Our programming languages--Python in particular--try to emulate English words and grammar.
Firmly in place in this world for many years, my first attempt to translate a pre-existing site came with a high sticker shock of nuanced difficulty. This talk covers all the lessons I learned in taking a fully-fleshed web app with no translation (and a programmer with no translation experience) to being completely translated.
