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.

PostScript, The Sequel

Send Article to a Friend

Adobe Systems Inc. announced its plans to announce PostScript Level 2 on June 5 of this year. Level 2 will incorporate all 52 of Level 1's extensions and will include new operators designed for Display PostScript. Level 2 will make PostScript more efficient and more powerful, and should increase processing speed significantly as well. Jill Kyte, manager of Adobe's product marketing group was quoted in InfoWorld as saying, "our number one issue with this revision is improved performance."

Adobe's announcement comes just days after its introduction of the Emerald, a raster image processor (RIP) controller that uses a RISC processor. The Emerald runs three to seven times faster than Adobe's older 68020-based Atlas controller. The Emerald controller and faster PostScript Level 2 can only improve Adobe's position in the competition with Microsoft and Apple's TrueImage (and HP's PCL-5).
