I can't be the only person here who loves Linux's persnickety, bookish older cousin. Discuss why you like BSD, What you're Using BSD on, Projects You'd like to do with BSD, BSD related content, and the like. (and try to keep the copyleft vs permissive flaming to a minimum)
Curious about BSD? Thirsty for BSD related content? Maybe give these guys a gander:
Currently I've got an old core duo macbook 1,1 running OpenBSD, A NAS and backup server running Freebsd, a PFsense router, entirely too many things that don't necessarily need it running on netbsd, and a website, mailserver, and desktop chugging along on versions of TrueOS.
Only BSD system I have at the moment is my pfSense router, I tried BSD on the desktop years ago for the lulz but not for very long, I may give it another look, I know @Adobe_Flash_Player is running BSD on a Raspberry Pi so I may give that a try.
Desktop isn't the strongest use case for it, but if you do, stick to OpenBSD or TrueOS. I love it for any type of web facing appliance or home network fixture though. netbsd is great for embedded dev, too. I've installed it on a bunch of "IoT" devices that supposedly need third party callbacks to function.
Apples Mac OS is open source. There was ( or is ) the puredarwin project ( I think that's he name ) where you can get the OS. You do not get out of the box the propriety stuff. I tried to install it once back in the day before I realized that you needed Mac compatible hardware. It failed, because it could not find the cpu cores, which I thought was a strange error.
Other then that, my only bsd experience was freebsd, which was a great experience.
