The Cyberduck team has released version 4.1 of the free file-transfer utility for Mac OS X. Cyberduck 4.1 adds support for navigation using trackpad gestures, allows users to upload arbitrary files to Google Docs, and introduces several improvements to its interface with Amazon’s S3 and CloudFront services, particularly in relation to storing data in different data centers and better managing log files. Rounding out the release are numerous bug fixes that correct issues ranging from managing the timestamps of uploaded files to ensuring that only trashed files are deleted in Google Docs.

Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
