In case you haven’t noticed, you can switch this blog from English to French and vice-versa by using the top menu in the left sidebar. Whatever part of this blog you are reading, almost all you see will be translated. Also, the menu on the grey bar under the header brings you to the main page in one of those two languages. This explains why comments are posted in English or French, sometimes both!
This blog runs the Polyglot plug-in, which can force the WordPress localization (its default language if you prefer). It does not perform the translation; this is done for every post by yours truly. It’s obviously a bit of extra work, but I think it is worth it just to reach the highest number of my friends and colleagues from the VFX community.
