That's what I've heard as well. I love the fact that IPv6 is developed on open source operating systems, and yet will hardly be accepted in the networking world until Windows supports it. | Other things which appear to be "breakthroughs" are just | concessions to hardware tradeoffs that are true today | that weren't true when the original implementations were | first deployed (e.g. relative cost of disk seeks vs. | speed on tracks, relative costs of main memory access vs. | cache access, etc.). Revisiting these tradeoffs is normal | and doesn't really count as "breakthrough" in my book. As I was writing my first email, I was wondering if this might describe some of the scenarios. I was especially thinking of the VM and FFS changes recently. It seems to me the new self-tuning ability of BSD's operating parameters would make it quite adaptable to different hardware environments. Wow. I really love this OS. :-) jm -- My other computer is your windows box. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
