Is a Laptop Touchpad Heat Sensitive?

My MacBook Pro display automatically reduces brightness before I finish reading one page, sometimes it returns to its full brightness or even wakes up from sleep before my finger touch the touchpad, i. e. it can sense my "touching" even when it was a couple millimetres above.

I wonder if the touchpad is heat sensitive. In an Answerbag post How does a laptop touch pad work?, I learned that "laptop mouse touchpad usually use heat to detect touch. "

But some say on a macbook it's not heat, it's conductivity. One guy tested a cold sterling silver ring, it works perfectly even when not in contact with his body. A 50 cent euro coin works, but a stainless steel Ikea fork does not - even if he warm it up and/or hold the fork. But I tried a sterling coin and failed. I couldn't move the mouse by a Pound Sterling.

A touch pad is a device for pointing (controlling input positioning) on a computer display screen. It is an alternative to the mouse. Originally incorporated in laptop computers, touch pads are also being made for use with desktop computers. A touch pad works by sensing the user's finger movement and downward pressure.

Virgin Media Netgear Wireless Router Username and Password

As Virgin Media customer, if you find your wireless router is Netgear, then you may type the router's setup URL into a web browser address bar. http://192.168.0.1 is the default Netgear router IP address. http://192.168.1.1 will work for some Netgear models. Mine setup URL is http://192.168.1.1 . Then you are required to enter a username and password. If you haven't change the default setting, it is "virgin" and "password", you may find that on a label stuck on the router. This default username and password of Virgin Wireless router is different from that of the normal Netgear router. The default username of Netgear is admin and the password is either password or 1234. Then you open the configure interface, change the settings, such as change your DNS server to OpenDNS .

URL cannot contain a Google host

Google just opened up Knol to the public. Knol is also serving up AdSense advertising on the site. Authors on Knol can enter their AdSense data into Knol, and will get the regular AdSense payout for every click on an ad. This seems like a smart way to reward users who write the best (or most popular) content, while still making money for Google, because the cut Google already takes from the advertising through AdSense anyway. Currently, I don't know how may we track ads performance on knol, I tried to add an URL channel, and got error message: "http://knol.google.com/k/-/k3-searching-tv-programs-using-teletext/2p3t2lhf3x6sj/6#" at line 1 invalid: URL cannot contain a Google host. Has anybody any idea of how to do it?
