This is a most excellent place for technology news and articles.
I will add to the agreement. I wish gpl was not needed. I did not realize any bsds used micro kernels though.
Now you've got me questioning myself, never claimed to be an expert...
Edit: yep I'm wrong, a microkernel was developed, but looks like it eventually made it's way to GNU Hurd and not really implemented into the BSDs. I recall coming across when looking into different OSs, I guess I got it mixed up.
