By Paul Rubens With growing numbers using wi-fi in their homes, Paul Rubens looks at how good security is on these networks. In less than two minutes hackers can defeat the security measures protecting many home wireless internet connections. Defeating these measures could let them capture passwords, steal confidential information or download illegal pornographic material using the connection. Many home internet users rely on an encryption system called Wired Equivalent Privacy (WEP) to stop others using their wi-fi link, even though WEP has long been known to be flawed. In early April three cryptographic researchers at the Darmstadt Technical University in Germany revealed a method of exploiting the flaws far more effectively. Before now it took at least 20 minutes of monitoring the airwaves before it was possible to break in to a wireless network protected by WEP. Now, armed with a program written by the researchers, it is possible to break in to the same network far faster. More her

The only rule in photography is that there are no rules . However, there are many composition guidelines which can be applied in almost any situation, to enhance the impact of a scene. Below are ten of the most popular and most widely respected composition 'rules'. 1. Rule of Thirds The most important elements (the horizon and the haystack) are placed on or around the lines and points of intersection. Image by Cayusa . Imagine that your image is divided into nine equal segments by two vertical and two horizontal lines. Try to position the most important elements in your scene along these lines, or at the points where they intersect. Doing so will add balance and interest to your photo. Some cameras even offer an option to superimpose a rule of thirds grid over the LCD screen, making it even easier to use.   More at Amateur Snapper

Inexpensive iPods, music-playing cell phones, and—heck—even PCs have essentially replaced the traditional stereo system. As the typical stack of 17-inch-wide audio components goes the way of the dodo, so too do their accompanying fiberboard shelving units stuffed with hundreds of plastic CD jewel cases. That doesn't mean that your organizational chores are over, unfortunately. The average music fan may have one or more PCs, an MP3 player, a cell phone, a car stereo, and other music-playing gadgets. And while you won't catch many of us returning to the days of physical media for music—despite what SanDisk may think—it's still tough to keep everything under control. With that in mind, power up your iTunes 8 organization, navigation, and maintenance skills with the following tips: Blogger Labels: music , cell , stereo , system , components , player , navigation , maintenance , tips , units , gadgets , skills , iTunes More at PC Mag

Before Windows 7 can be useful, you need to understand how it organizes your data. Here's a look at a new feature in Windows 7 called Libraries. Windows 7 has its share of highly visible user interface tweaks. After getting past the oohs and aahs of the spiffed-up taskbar , you'll likely find the new look of good old Explorer the most dramatic difference. Click the Windows Explorer icon on the taskbar, or open Computer from the Start menu, and you'll get a window that displays not only the standard expandable hard drive labels but also a new feature called Libraries.   More from PC Mag

“ Like many of you, I got a kick out of flying to my house the very first time I used Google Earth. But after I'd had enough of zooming, tilting and panning around my neighborhood, I wound up asking myself, "What next?". I knew that Google Earth could take me virtually anywhere I wanted to go. But West London, England, is where I grew up — before I sought out new places, I wanted to see what Google Earth could show me about my own home turf that I didn't already know. As it turns out, it showed me quite a bit, and it was turning on the Google Earth Community layer that really made my neighborhood come alive. The Community layer showcases placemarks posted to the Google Earth Community by users: Google Earth fans who seek out the coolest places and want to share them. These range from natural phenomena visible from above, to the biggest man-made structures that represent the greatest engineering feats. Near my home, however, I found that the Community laye
