A Hacker News thread about FreeBSD vs. Linux.
I moved from Linux to FreeBSD. FreeBSD is running on the dedicated server now. At the time of writing this post, the DigitalOcean droplet is still running but after I move all the data to the dedicated server I will delete the droplet.
My FreeBSD favorites: ZFS and jails.
My favorite desktop OS is still Mac OS X.
Btw, the dedicated server would run Solaris 11 but iRedMail does not support Solaris so I chose FreeBSD for the server. But Solaris is on my NAS.
Speaking of NAS, if you are looking for a NAS, I recommend HP ProLiant MicroServer N54L. Not expensive and with ECC RAM.
