My reaction to Solaris 10 update 6's ZFS changes
I've been talking about my wait for Solaris 10 update 6 for a while, because it promised improvements and bug fixes for various ZFS issues that had been giving me heartburn. Since it's been out for a while and we've actually put it into production on one server, it's about time I did a review on how its ZFS changes stack up.
If this is all opaque, see the Solaris 10 update 6 release notes for background on these new ZFS changes and features.
Note that currently I have not tested how well the new host ownership of ZFS pools works, so I have no opinion on that. It's not a high priority, since even with the S10U6 ZFS features I still feel that easy failover will be too fragile to make me happy.
(We would need two S10U6 test machines in order to test it out, and so far we have only ever had one.)

How LiveJournal is sticky
Given the recent commotion over some of LiveJournal's business decisions and people's unhappyness with LiveJournal as a result, I've been thinking about the various ways that LiveJournal makes itself sticky (and thus hard to leave, and so on). I think that there are three general levels of LiveJournal stickyness, in ascending order:
I think that a lot of discussion about how people can (or can't) just migrate away from LiveJournal miss the incredible stickiness of the last level. Given that people are social, enabling that sociability is a very serious attraction.
These days, blogs can be user friendly (and there have always been places that let you easily create a blog of your own) and syndication feed readers and aggregators can lower the network effect, but I don't think that there's anything that can substitute for the third level. It's hard to see how there could be in the near future, because there are a horde of hard problems to be solved (starting with automatic cross-site identities that work through your syndication feed reader).
(Communities form even without these enabling features; I would be remiss if I didn't mention the anime blogging community as one example. But I think that the social features that LiveJournal has make it much easier to have communities form and stay, and to make it so that new people can more easily get pulled into them.)
