A while ago I had the pleasure to go on a Sun training course for Solaris 10, covering the new features. I had a mixed experience to the content of Sol10 (or perhaps that might have been "the content of the course"?), and with the excuse of keeping notes about what we covered, I bloged about it.
It may be fair to describe blogging as ranting :-) but that's probably true of virtually everything on the web that wasn't directly paid for. And even some of that, too!
The article probably wasn't very widely spread, but did find its way onto the OpenSolaris discussion list. Here's the discussion
There are valuable and interesting technical clarifications and refutations in that discussion, so it's worth reading. I'm adding a link to the discussion onto the end of the article as well.
