I think the coolest thing is the new wiki version of the Solaris DTrace Guide. This is the same book published on docs.sun.com, but you can now share your DTrace knowledge by adding to the wiki version.
Speaking of wikis, Solaris Cluster has a great new wiki. It serves as an information center for Solaris Cluster and has lots of good stuff there already. You can add information and share what you know about using Solaris Cluster.
BigAdmin has a new virtualization site covering all Sun's virtualization technologies like Zones/Containers, LDOMS, and xVM hypervisor. This is a very rich site with information on:
* Server virtualization
* OS virtualization
* Storage virtualization
* Desktop virtualization
* Application virtualization
* Network virtualization
Big news for Solaris this week are the InfoWeek awards. One for ZFS and another for Solaris 10.
InfoWeek says of Solaris 10 that "No server operating system satisfies more varied requirements or boasts a wider range of brilliant features."
Of ZFS, InfoWeek says, "It's not every day that the computer industry delivers the level of innovation found in Sun's ZFS. The fluidity, the malleability, and the scalability of ZFS far surpass any file system available now on any platform."
There are a bunch of other worthwhile new stuff: articles, blogs, and updated web sites. It's a hefty list. Like I said, people have been busy.
