previewing Ubuntu Savvy
One of the key design goals we had in mind when we set out to create Ubuntu for phones and tablets (henceforth abbreviated here as Ubuntu Devices (vs Ubuntu Desktop)) was how to balance continuing our rich heritage of downstreams, be they community remixes or commercial products, against the idea of preventing platform API and UI fragmentation, which is the Android antipattern.
A while back, my boss Victor wrote a blog entry titled Differentiation without fragmentation which gives a key insight as to why fragmentation occurs:
Fragmentation occurs when the software platform fails to provide a supported mechanism to differentiate.
Victor then goes on to describe our Scopes framework which is a core design concept that spans implementation, functional, and visual layers to enable our downstreams to differentiate.
Part of my job is making what Victor says actually come true, and as we started thinking through the actual mechanics of how our downstreams would start with a default Ubuntu Device image and end up with a customized version of it, we realized that the nuts and bolts of what an OEM engineer or enthusiastic community member would have to learn and understand about our platform to actually make a working device image were too complex.
So we roughed out some ideas and after several months of iterating in private, I’m pleased to announce the preview of the Ubuntu Savvy phone customization suite. It consists of several parts:
Source branch and test suite, open for all to see: bzr branch lp:savilerow
Readable documentation, from big picture down to nitty grittys. You can preview it for now at people.c.c/~achiang/ubuntu_savvy but it will eventually move to developer.ubuntu.com
Shiny tools, some prototyped, some planned. Preview at lp:~achiang/savilerow/tailor-poc but will eventually move to its own LP project
If you are interested in learning more about our plans or you have ideas for ways that you’d like to customize your version of Ubuntu or you’re interested in improving code, tests, or docs, please come to our vUDS session.
Carrier/OEM Customizations on 2014-03-13 from 15:00 to 15:55 UTC.
A final note, Ubuntu Savvy builds upon a lot of work, from the fine folks in UE who helped design a flexible, decoupled image architecture, to the SDK team for providing some nice QML code for us to re-purpose, and to my entire team, both present and emeritus (such as mfisch and sfeole). Thanks to all.
We invite the broader Ubuntu community to help tinker with and tailor Ubuntu.
Upward and onward!
