Postfix supports IPv6 from version 2.2 and up. By default only IPv4 support in enabled. Enabling IPv6 is as easy as adding one parameter to Postfix’s main.cf:
/etc/postfix/main.cf:
# You must stop/start Postfix after changing this parameter.
inet_protocols = ipv4 (DEFAULT: enable IPv4 only)
inet_protocols = all (enable IPv4, and IPv6 if supported)
inet_protocols = ipv4, ipv6 (enable both IPv4 and IPv6)
inet_protocols = ipv6 (enable IPv6 only)
Be sure to also update match lists as mynetworks and debug_peer_list with relevant IPv6 addressing.

LockTight Secures Your Mac With a Hotkey
Mac OS X only: Screen locker utility LockTight adds a shortcut key combination for OS X users to quickly lock your workstation from the keyboard.
Windows users switching to using a Mac might be surprised to find no equivalent to the Winkey+L shortcut combination that locks the screen, especially helpful in work environments or at home to keep little fingers from opening things they shouldn’t.
LockTight plugs into OS X as a simple system preference pane with a configurable hotkey, but for full effect you might want to configure your Mac to require a password when coming back from the screensaver and disable automatic login. Hit the link for the download, or take a look at the Switching to Mac guide for all the steps.

Git changes the game of distributed Web development: “Version control systems are a core component of most development projects, regardless of whether you’re developing an application, a Web site, or an operating system. Most projects involve multiple developers, often working at widely separated physical locations. Distributed version control systems are nothing new, but the Git version control system provides unique support for collaboration and interaction among developers.”
