Andrew started back at school last week, but this week he started taking the bus in the morning and he is so excited! The bus stop for our street is right at our house, so he keeps looking out the window to see if anyone else is out there. From the time he gets up until the time he goes outside he keeps asking Lisa how much more time there is until the bus comes. It's very cute!
I got more memory for my new computer (now 2GB total) and a proper cable for
one of my SATA drives, so I'm pretty well all done now. I'm sitting here listening
to Ella
Fitzgerald while
I type this looking at my flat screen (only 17", but it's my first one
I've ever had). One of the things about this computer is that it is virtually
silent!
My other computer sounded like an airplane. I was just used to it I guess.

US concedes danger of cyber-attack
George W. Bush has acknowledged that the US is vulnerable to cyber-attack and said he might raise the issue with Chinese President Hu Jintao when they meet in Sydney on Thursday.
The US president's comments followed a report in the Financial Times that the Chinese People's Liberation Army had allegedly hacked into the Pentagon's computer network.
"I'm very aware that a lot of our systems are vulnerable to cyber-attack from a variety of places," said Mr Bush, who is in Sydney for the annual Asia-Pacific Economic Co-operation (Apec) summit.
Can Michael Dell Refocus His Namesake?
On a recent afternoon at his company's headquarters here, Michael S. Dell is seated in a spacious conference room named Dobie Hall - in honor of the University of Texas dormitory where, in 1984, he started the computer giant that bears his name.
He boasts that Dell Inc. has just reported quarterly profits that exceeded Wall Street projections. It's an encouraging sign, he says, that the company - buffeted by high-profile production problems and accounting shenanigans - is finally regaining momentum.
Computers' Elusive Eco Factor
Consumers who want to weigh how their purchases affect the environment have plenty of guidelines and seals of approval to choose from for everything from cars to tissue paper. But finding out just how eco-friendly a computer is can be a bigger chore.
There are several competing yardsticks, each considering a different aspect of a computer's greenness, be it energy consumption, use of toxic materials, or how easily it can be recycled. None by itself provides a complete picture. And since consumers aren't demanding environmentally friendly computers in large numbers, makers of those machines have little incentive to market PCs that way.
Using Opacity in Photoshop for Fine Tuning - Digital Photography Tip of the Week
Adobe Photoshop and Adobe Photoshop Elements are both powerful photo editors. For the hobbyist, Photoshop Elements can be used to handle most, if not all of your photo editing needs. For serious photographers and professionals, the full version of Photoshop offers more tools for complete control over your photos. Both programs, and many other photo editing packages, feature the same, or similar tools and features. One such feature is the ability to control opacity. I have referred to opacity in previous tips: Feel the Burn, The Orton Effect, and Black and White from Colour Images, Part 4
Opacity refers to the intensity or transparency of a modification. You can modify opacity with brushes when painting effects in your images, but you can also use opacity on layers. When you are painting on a layer with a brush, modifying your opacity allows you to control how much paint you use. A low opacity results in a very light application of the brush while a higher opacity results in a heavy application. A lower opacity allows more of the original pixel data to show through while a higher opacity has a greater effect on your image. When using a brush, I prefer to use multiple strokes of a low opacity brush so that I can better control my adjustments rather than a single, heavy handed stroke.
With layers, opacity is a wonderful modifier. Like with the brushes, opacity control on a layer controls how transparent the layer is. I use this often to control how much or how little of an effect I want to use on an image. As I make use of a large number of adjustment layers, which in themselves may be altered again and again without pixel modification, I can also alter how strong the adjustment is. What I typically do is create my adjustment layer at 100% opacity and then dial the opacity down until I achieve the exact manipulation I am looking for. This is a great technique when touching up a portrait as I can hide or eliminate facial blemishes, whiten teeth, erase wrinkles and have precise and easily adjustable control over these changes. By lowering my opacity, I allow the underlying pixels to show through which helps to add texture to my changes and makes them completely lifelike.
With all the tools available in today's digital editing packages, the process can become daunting. Fine control may be difficult for someone new to the area of digital editing but working in small amounts can make it much easier. Being able to control your entire image is the goal of many photographers and tools such as opacity help with that.
Until next time, happy shooting.

Download free hard disk imaging utilities for Windows XP
This is from the TechRepublic Microsoft Windows Blog:
Windows Vista's hard disk imaging utility, Complete PC Backup, allows users you to create an image file that contains the complete contents and structure of a hard disk. If you want this capability in Windows XP, you don't have to pay for a third-party utility, such as Acronis True Image.
Your Computer. Leave Home Without It - ajaxWindows
Michael Robertson, the founder of MP3.com, has been promoting open source software for a while now. He recently started working with a company, Ajax13, that is writing web-based office-suite applications. The latest venture is a Windows replacement called ajaxWindows:
(image courtesy of Download Squad)Today I'm launching ajaxWindows - a complete virtual PC you can experience using only a browser from any web connected computer. If you would like to see it in action, check out the online demo or the video. Remember that everything you see is happening within a web browser. The web browser functions as both the operating system and engine for all of the ajaxWindows applications.I first heard about this yesterday, and the site was available, but I guess word has gone around, and it is currently unavailable. Over the next few days check it out. This particular setup is in its first version, so there is work to do, but this sort of online virtual computer is the future.
Windows Directory Statistics
There are many utilities out there that will show you the space used in the various folders on your system. One of the better ones is WinDirStat.
WinDirStat is a disk usage statistics viewer and cleanup tool for Microsoft Windows (all current variants).WinDirStat reads the whole directory tree once and then presents it in three useful views:
* The directory list, which resembles the tree view of the Windows Explorer but is sorted by file/subtree size,
* The treemap, which shows the whole contents of the directory tree straight away,
* The extension list, which serves as a legend and shows statistics about the file types.
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:
