I had a great long weekend away with my family. The weather was beautiful and we had lots of fun. There was fishing, swimming, camp fires, hikes, and more. I wish I was independently wealthy so I could retire and live up there. Unfortunately I still have 20+ years to go!
Is it just me, or is all the buzz these days about some sort of entertainment device. Am I the only one who uses their computer for computing, and not for watching TV/movies or playing games? I just don't understand what all the fuss is about. Any thoughts?

Your Life as an Open Book
Privacy advocates and search industry watchers have long warned that the vast and valuable stores of data collected by search engine companies could be vulnerable to thieves, rogue employees, mishaps or even government subpoenas.
Four major search companies were served with government subpoenas for their search data last year, and now once again, privacy advocates can say, "We told you so."
AOL's misstep last week in briefly posting some 19 million Internet search queries made by more than 600,000 of its unwitting customers has reminded many Americans that their private searches - for solutions to debt or bunions or loneliness - are not entirely their own.
So, as one privacy group has asserted, is AOL's blunder likely to be the search industry's "Data Valdez," like the 1989 Exxon oil spill that became the rallying cry for the environmental movement?
Terabyte drive to debut later this year
If there's a storage fanatic in your family, a perfect gift could be coming for her or him toward the end of the year: 1-terabyte hard drives. Desktop hard drives holding 1 terabyte, or 1,000 gigabytes, of storage will likely debut in 2006, according to Bill Healy, senior vice president of product strategy and marketing at Hitachi Global Storage Technologies. These drives, which will have a 3.5-inch diameter, are expected to be incorporated into PCs and home servers.
Users still not wiping data from unwanted PCs
Research by BT, the University of Glamorgan in Wales and Edith Cowan University in Australia, has found that while 41% of the disks were unreadable, 20% contained sufficient information to identify individuals.
The research, based on the acquisition of 300 PCs from auctions, computer fairs and on-line purchases, also found that 5% of the machines held commercial information on organisations, and that 5% held "illicit data".
Black and White from Colour Images - Part 2 - Digital Photography Tip of the Week
Last week I began my discussion of black and white digital photography. This week I will further that discussion by talking about the first two methods of converting your digital photographs to black and white, or more specifically, monochrome. For the sake of simplicity, I will use black and white in my text, but even traditional wet darkroom methods had ways of introducing a color tint or tone into an image, so monochrome is a better descriptor for the final images.
The two methods of black and white conversion I will discuss this week are desaturating the image and converting to grayscale.
Saturation refers to the intensity of the colour in your photograph. An image with bright colors have high saturation while image with pastel colors have low saturation. If you remove all the colour saturation in the image, you end up with a photo that looks like a black and white image.
To desaturate an image in Adobe Photoshop Elements 4.0 , from the menu choose Enhance => Adjust Color => Adjust Hue/Saturation (CTRL-U). Then, simply drag the saturation slider all the way to the left. The same shortcut works in Adobe Photoshop CS2 , but the menu location is different. In CS2, use Image => Adjustments => Hue/Saturation. However, in order to preserve image data, I prefer to create an adjustment layer using Layer => New Adjustment Layer => Hue Saturation. Again, simply slide the Saturation slider to the left. Using desaturation to remove the colour from a photograph affects the red, green and blue channels equally.
Converting to grayscale is a very simple process, but it changes the data in your image. If you are converting to grayscale, you probably don't need the color data anyway. When converting to grayscale, Photoshop places more emphasis on some channels than others, in the proportions of 30% Red, 59% Green and 11% Blue. This provides a more natural conversion of your photograph and more closely resembles what we expect to see.
The example above shows four colors in the first row, red, green, blue and yellow. All four have the same brightness (or luminance). The second row is the same four colors, only this time they have been desaturated. Because they are of the same brightness, once desaturated, they look the same. Finally, the third row is the same colors but this time they have been converted to grayscale. As you can see, There is an obvious difference.How do you know when to use which method. Using the desaturate creates a very flat image that is rarely, if ever, very impressive. Converting to grayscale is the obvious better choice. It should yield acceptable results, most of the time. Is the best choice? If you are using Adobe Photoshop Elements , it is. If you are using another program, such as Microsoft Digital Image Suite or Adobe Photoshop CS2 , there are still better ways.
Next week I will talk about using Channel Mixer to convert you colour photographs to black and white masterpieces.

eBay auctions in the news
King Nutter is a British site (I'm not sure what the name means) that tracks unusual eBay auctions. You can read about auctions that include buying a town, a 1993 school bus, Brokeback Mountain Pez dispensers, and a guy selling everything he owns. If you've got a few minutes to sell, then check it out.
Note that there are other areas to the site that I didn't visit so I don't know what they are like or what they contain.
Both of us have other sites other than PCIN.net. These are all sites that we are actively involved in (they aren't client sites). Don't forget to check them out from time to time for updates:
