In today's Remainders: the many. A new multitouch test app shows that multiple fingers confuse the Nexus One; Windows 7 has sold multiple copies (roughly 90 million); Chrome and its numerous extensions are catching up to Firefox, and more

MultiSlouch
Nexus One users have been reporting some multitouch wonkery for a while now, and to get to the bottom of things Robert Green put together the Multitouch Visible Test. The application, available now in the Android Market, basically does what its name suggests, visualizing input by placing colored dots on the screen where it registers your fingers. The first test, on the Droid, runs fine—the dots stick close to the fingers the whole time. On the Nexus One, however, the dots flip around and track to the inverse when the fingers get too close. Google engineer Diana Hackborn responded to the video in a post on the Android developers group:

this is how the touch screen hardware on the Nexus One works (which is essentially the same screen as on the G1 and myTouch). The Droid has a sensor from a different manufacturer, with different behavior. Other phones will likewise have different sensors.

Sorry, Nexus One users, it looks like you might be stuck with the wonkery. [YouTube via AndroidandMe]

The spot uses aliens as a metaphor for internet users, showing how a worldwide network of disembodied individuals can summon the compassion and intelligence required to help humankind through its "infancy" period. Yeah, humankind, that's great. But superpowers? And aliens?! That's how they're really gonna hook the geek community. [Buzz Feed]

Shiny
In just the few short months that they have been available for Google Chrome, developers have put together over 3000 extensions for the growing browser. Depending on how you count—Mozilla hasn't released an official number—Chrome has somewhere between one quarter and one half of the extensions as Firefox, which has been racking them up for a considerably longer period. How to account for Chrome's extension explosion? It could be its approval process, er, lack thereof. Whereas Firefox's add-ons spend some time in a review period, Chrome's zoom into availability as soon as they're submitted. Chrome's extension windfall will be bolstered by a recent announcement from Jolicloud, makers of
