Can't find any Wireless Network??

My friend's DELL laptop suddenly can't find any available wireless network. It works fine before that and usually she can get a few networks available in her area. I have double check the wireless network card and try to turn on the Wireless Zero Configuration (WZC) feature on the laptop, but it still didn't work.

The problem solved when i apply the Fn+F2. This feature only apply for Dell's Laptop which we can turn the Radio on / off by applying Fn+F2. I think she was accidently off the radio on her laptop, and that's way the wireless card is disable and can't detect any wireless network.

However, i did learn new thing when i try to repair her wireless network connection. WZC is a feature available in Window XP. Sometimes, when the software come with your wireless adapter's manufacturer cannot help you to get the wireless connection up, you might wanna turn on the WZC feature in XP, so that you can use the XP's native support for wireless networking. It can be turn on by taking steps as below:

1. Start > Run> type "services.msc", and click open
2. Scoll down and looking for "Wireless Zero Configuration" service and select and double click on it to open up the propertise window.
3. Select "Startup Type" as "Automatic".
4. Click "Start" at the "Service Status".
5. Click "ok".

You can now have XP to manage your wireless connection.

Interested to get knowing your genetic Blueprint?

It is interesting to know, the technologies are now enabling us to sequence up our genome and understand our own genetic information from our 23 paired chromosome. However, to read trillions of copies of genome in a single human body is expensive. It may simply cost a million USD to do that. 23andMe, a private held company in California is currently working into this, so that the cost can be bring down to USD1000 with advance sequencing technologies. You can see an example on James Watson (co-discovers of DNA's double helix structure) personal genome's structure on this website: http://jimwatsonsequence.cshl.edu/cgi-perl/gbrowse/jwsequence/

I read about this in the NewScientist Magazine. Just wonder if they can sucessfully bring down the genome screening price to an affordable one, and also provide the information hide inside the DNA, there will be a new business market then. I mean, it is no point just get knowing the sequence and you can do nothing to change anything, rite?
