> Interestingly, Google does respect the Accept-Language header.
Google knows I use/want English. It knows this because I'm logged-in and have set my preferences, but also because of that Accept-Language header my browser sends in every single request. Yet for years, perhaps because I am 20km from Germany, it has assumed I would always prefer German when doing social sign-in.
Google may occasionally glance at Accept-Language, but it does not respect it. It even demotes my own logged-in preferences below a guess based on my location.
When there are no other indicators, fine, guess my language from my location, but otherwise location != language. But I know for fact that my browser is sending out Accept-Language headers in a convenient format that will tell you all you need to know.
Small thing / pet peeve: the website sets language based on my location rather than on what my browser is telling it is my language of choice in every single HTTP request.
From rwmj's comment that "every distro except Ubuntu has to set up an external CI server in order to get their drivers and changes in" I gathered that Ubuntu was the distro of choice for CI, so that's what I should have written: for CI. I didn't mean to say that Ubuntu is the OpenStack project's preferred choice for deployment.
The single largest contributor by the metrics you posted. There are other types of contribution, integration and distribution for example, things that Ubuntu has traditionally focused on instead of raw upstream work.
By head count, Red Hat is 10 times the size of Canonical. This means that Canonical would not be expected to show in the graphs you linked to, given the same level of activity averaged per employee. Yet Ubuntu is the distro of choice for OpenStack. That speaks to the strength of the community around OpenStack on Ubuntu, the skill and commitment of the people working on it, and the quality of the experience.
As to the grumble about spinning up an external CI server: you'll be glad to know that Ubuntu is really easy to spin up on bare metal or in VMs, and you don't have to buy licenses ;)
Disclaimer: I work for Canonical, so I am totally biased. I don't work on OpenStack, but I know many of those who do.
First reaction: the bland beige looks terrible (maybe that's because I'm not American; I always notice that 1/2 of everything is beige when I'm in the US). Combine that with the name and I'm reminded of the Persona contraceptive device.
