i18n? wtf?

@elibelly
Numeronym
A number-based word, for example:
-
Numbers as sounds: K9, l8r
-
numbers as meaning: 411, 007
-
adding up the number of letters between the first and last and then using that number instead of the middle of the word, wow, what a good
idea : i18n, l10n, a11y -
... n7m

InternationaliZation
If you internationalise, you design or develop your content, application, specification, and so on, in a way that ensures it will work well for, or can be easily adapted for, users from any culture, region, or language.

Continuous Localisation
- ease
- price
- services & features
It is a way of automatically, seamlessly gathering new source material, publishing it for translation, acquiring translations and integrating them back into the product.
i18l has a logistics problem
I18n is much easier to integrate into your project early

- Internationalise all the things - I18n is part of accessibility
- I18n is supported by a bunch of standards, helps do it "right"
- Try to start early if you can
- Always let your user pick their own locale
- German is a great first test language!
🙏 Thank you 🙏

Internationalisation is a Piece of Cake - Codemotion Berlin
While about 51% of the world’s websites are in English, only about 25% of web users are English speakers. With half of the world’s population online, internationalisation is as relevant as ever! Let’s explore how i18n gets made on the web.
