I am the Ubuntu Kernel Team Bug Triager. That basically means, if it is a bug on the kernel as shipped in a supported Ubuntu release, I manage it. This currently to the tune of 10,000+ bugs just on the linux(Ubuntu) package.
I work with the smartest team of people I have ever had the good fortune to come across, and I am thankful every day that they are so much smarter than me because they tend to see my errors before I make them public. ;-) If you have some time and you are interested in the inner workings of the Ubuntu kernel, feel free to come see us on FreeNode in the #ubuntu-kernel channel. There is a place for everyone.
Which brings me to another large part of my job, Ubuntu community involvement. If you are unfamiliar with how the Ubuntu community works, I can tell you that it is like one very big family all working together to make Ubuntu the best that it can possibly be for each release. Check out the pages here for more info. I can sure use the help managing the bug backlog for the kernel, so if you are interested in the kernel or in bug triage itself, chat with me on FreeNode and let me know you want to help.
That is all for now. Carry on.
