Author and media theorist Douglas Rushkoff has quit Facebook, but for a reason that goes beyond the usual concern with Facebook’s privacy problems. He says: “Through a new variation of the Sponsored Stories feature called Related Posts, users who ‘like’ something can be unwittingly associated with pretty much anything an advertiser pays for. Like email spam with a spoofed identity, the Related Post shows up in a newsfeed right under the user’s name and picture. If you like me, you can be shown implicitly recommending me or something I like — something you’ve never heard of — to others without your consent.” We find that exceedingly troubling, since it means that you lose even more control over your online persona on Facebook. follow link
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
