While apps like Google Chrome and CrashPlan seem to have no trouble updating themselves automatically, Dropbox continues to stumble in that area. If your copy, like ours, hasn’t updated (hover over the Dropbox icon in the menu to see the version in a tooltip), you might want to download Dropbox 1.6.0, which promises faster startup times for users with lots of files, improved overall performance, and improved Web login from the Dropbox client app. The update also features new icons that will look good on Retina displays, a new installer that doesn’t require that you quit the older version first, and translations for Italian and Iberian Spanish. Or just wait — Dropbox might update itself eventually. (Free, 23.1 MB, release notes)
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.
Air Display 2 lets you use your iPad, iPhone, or nearby Mac as
extra screen real estate for your main computer. Now smarter,
better, and 50 percent faster. <http://avatron.com/tidbits>
Note that the post says, "Since it's a Holiday here in the US and we're all gonna be eating Turkey for the next couple of days we will not be auto-updating or posting this to the front page until after we get back. But if you're having any kind of problems with 1.6.0 this is the build for you."
I personally think Dropbox should just enable manual upgrades from within the client app - that way those who want the fixes can get them without having to hunt through random blog posts on the Dropbox site or wonder why they don't have the same version as Dropbox is distributing on its main page.
