It would do you well to stop being so hurt that you didn't get credit or recognition for the work you did. Why didn't you blog about it instead of being pissed off Sun engineers get the credit?
Yes I'm a big fan of their work, not least because their products work damn well, especially when solutions in GNU/Linux are compared to theirs. Did they screw up over the years? Yes they did, the USB subsystem in Solaris is an infamous fuck-up of epic proportions. Ironically it has nothing to do with distributed systems. But the things they really put effort into like Sun clustering, NFS and networking work and work damn well.
As for me and learning something new, I do that all of the time. The problem is that most of the new things coming out aren't new at all and certainly aren't better.
And you know what, for a passionate computer enthusiast, I'm sick and tired of IT and all this bullshit.
Please, try learning something new instead of getting stuck on the first thing you found when you first entered the industry and spitting all over everything else. Go look through the conference proceedings, even from Sun's glory years, and you'll find plenty of papers from people elsewhere that have had a far more profound effect on software practice today. This fanboi behavior does nobody any good, least of all you.
