I have spent 2+ days to read all the Accessibility Team member's blog. It's very useful for me to understand the concepts of UIA, ATK, at-spi and something like that.
As a packager, I am keeping going to familiar with OBS (OpenSUSE Build Service) and also openSUSE (I was Ubuntu user). As a new user of openSUSE, there is a little bit intolerant about the software management, which is the part of YAST2. When I change a little, it configure everything for me! This might takes me many days to get known to openSUSE and its philosophy, but I believe it's worthy to doing that .
