IT organizational structure.
Lately, I have heard more and more about various IT management strategies. The ones that keep coming up are the matrix and Prism approaches to IT. CIO's need to understand the depth first model and organizing around business Unit don't work. They squelch outside aggravations immediately; and then breed ineffectiveness and inefficiency through out the organization. In tight time almost everyone has decided IT organizational structure should not mirror business structure. By organizing IT like the rest of the business; you build in the politics and in-fighting that exists elsewhere.

ZFS.
I have been a fan of Solaris since it went open. I used it before but I was just an admin. Now I am slowly becoming a zealot. Good, example; today I wanted to update the Sun Ray server to firefox 3.0.5 from SFW. I didn't want to mess up anyone else's surfing and wanted to be able to roll back with little to no hassle. ZFS to the rescue. I snapshotted the filesystem. zfs snapshot rpool/usr@today. This is too easy. I pfexec /usr/sbin/pkgadd -d firefox... I check firefox. It looks ok. I ask other users to try it and it doesn't work for them. I try to troubleshoot for a little while, I can't figure out why it only starts for half the users Its probably a permissions problem, but I don't have the time to figure it out soo.
zfs rollback rpool/usr@today and everything was working again. I need to find an easy way to do something similar with Linux. It is amazing when it just works.
