Bose Noise Cancelling Headphones Reviewed
by: Steve Joseph
Well almost anyone will tell you that Bose are currently the benchmark for noise cancelling headphones. Their QuietComfort 2 headphones offer superb noise reduction and extraordinary sound quality over their competitors. The over the ear or circumaural headsets are simply a cut above what Sony, JVC and Sennheiser are currently offering. Enhanced audio performance and styling are packaged in a lightweight and comfortable unit that conveniently folds flat for travelers. However consumers can rest assured that Bose’s competitors will undoubtedly be developing new models, aimed at trying to knock Bose of its perch in the near future, but for now lets see what make them the market leaders.
Bose has been at the cutting edge of noise cancelling technology for years, holding a US patent on Acoustic Noise Cancelling Headphone Technology. This mouthful translates into an electronic system that is extremely effective at reducing ambient noise without compromising the music or movie dialogue, says http://www.cancellingnoise.com. This ability to reduce unwanted noise while still preserving the desired sounds is obviously the crux of active noise cancellation and Bose simply do it better than the others.
FTP - File Transfer Protocol Explained
October 22, 2007
File Transfer Protocol (FTP) is a protocol that is part of the TCP/IP suite. It is the standard for transferring large amounts of data from server to server and from servers to clients. There is a very good chance that you have downloaded files from FTP sites many times, though it may have seemed you were only downloading from a website. FTP allows you to transfer files over a variety of hosts with different operating systems and file systems. There are so many FTP servers on the Internet, some are private with secure logon names, other ones are public with anonymous logins.
This paper will give a very brief outline of how the FTP Protocol functions and give the basic commands used during an FTP session. Keep in mind that these commands are generally automatic and are executed by either an FTP Client application, or done via your web browser. Though these methods are generally quicker than manually connecting to an FTP, it doesn’t mean we should ignore the background behind how the technology works.
Is Your Mobile Device Secure?

Is Your Mobile Device Secure?
by: Darren Miller
How Secure Is Your Mobile Device?
Do you own a keychain USB jump-drive, a PDA, or an
all-in-one mobile communications device? If you do, what
type of information do you store on it? Many people would
say there is nothing important stored on their mobile
device. Many of our customers initially state there is
nothing on the computer network that hackers would want or a
virus could irreparably damage.
I want to start out this article with a couple real-life
stories about why it is so important to make sure your
mobile devices are secure.
Panic Over Lost Jump-Drive
About a year ago, a business acquaintance contacted me in a
panic. Apparently, he was onsite performing an internal
security audit for a rather large company, and had lost or
misplaced his keychain USB Jump-Drive. At first, I was not
sure of why he was in such a panic. That is, until he told
me the drive contained approximately 300Mb of security
What Are You Looking For In A Cheap MP3 Player?
October 20, 2007
Are you stymied by the vast offerings in cheap mp3 players? Don’t know which features best suit your needs? Here are some suggestions based upon product reviews by mp3 player owners.
The first thing you must consider is how you plan to use your mp3 player. Do you want a cheap mp3 player for your car to listen to books while you commute? Or are you planning to use it with earphones while jogging? Will your mp3 player sit on your desk all day, or get jostled around while you run errands or work out at the gym?
If you plan to be active while listening to your mp3 player, or use it in a car, one that uses Flash Memory, with no moving parts, would be the best option. There are cheap mp3 players available with Flash Memory, but they tend to be more expensive than other options. If you wish to keep the price down, you will probably end up sacrificing on some of the data storage. If you are planning to keep your mp3 player immobile, a cheap option is to buy one with a microdrive, or one built into a cheap CD player. Both will have problems with skip if jostled, but each of these two options will give you many times the memory for far less. Also, manufacturers build buffers into mp3 players to smooth out the skip, although users report that they do not always work well.

Mp3 players : Flash | Hard Drive Which One Was Made For Your Music?
by: Daryl Plaza
The evolution of the mp3 format has allowed us to compress music files also known as (mpeg-1 audio layer 3 file) so that we can store and take our music anywhere in great amounts. Here is a comparison of the two so you can decide which mp3 player storage style is best for you.
Flash mp3 players
Flash memory (non-volatile memory) means any information or music stored on it is less accessible to loss. All data is stored on chips which means even turned off you won’t loose data. With non-moving parts it is great for the active person and you won’t be worried about skipping or jogging of the music. The memory size is not as big as it’s counterpart but does have it’s own benefits. Flash memory players are small and lightweight so for using them on your daily commute or music on your daily run you just put them in your pocket or off a neck chain and have more than enough music on it.

The Advantages of Portable MP3 Players
October 18, 2007
With their solid-state technology, compact size, and abundant memory, portable mp3 players are the state of the art in portable music systems.
Most portable mp3 players feature storage systems that have no moving parts. This gives mp3 a distinct advantage over other portable music players, such as CD players, because there is no chance of skip, whether the user is jogging, taking a bumpy car ride, or cycling on a dirt path.
The mp3 songs, or other audible media, are usually stored on Flash Memory systems, either built-in or on the Sony Memory Stick, SmartMedia, or CompactFlash cards. These are the same cards and sticks that are often used for digital cameras, and work with the portable mp3 player in a similar manner.
Mp3 files are first prepared on a personal computer, either by downloading music from the Internet, compressing songs from a CD format, or creating original music on mp3 software. The files are then downloaded, via the computer’s USB port or parallel port, directly into the mp3 player, or into a reader or removable drive that takes the card or stick of choice. Many portable mp3 players come with software programs to assist with the download process.
Thought Control

Thought Control
by: Steve Gillman
Thought control? How would you like to be able to turn on your television just by thinking? Or have the door to your house open by mind power when your hands were full? This isn’t something that will remain science fiction for long. The technology necessary to make this happen is here now.
First of all, you have basic thought control now, meaning you can control and direct your thoughts. You can imagine a friend talking in your mind, for example. Then you can choose to hear music in your imagination. If you are hooked up to an electroencephalograph when you do these things, it will also be clear that these two thoughts are handled in different parts of your brain.
This electroencephalogram, or EEG, is important, because what we can measure, we can use to do things. Think about this for a moment. Modern electronics has made it possible to easily operate things as a response to measurement. A thermostat measures the temperature, for example, and turns the heater on or off according to that measurement. Security lights turn themselves on when light levels get low.

Desktop Security Software Risks - Part 2
October 17, 2007
This is the third in a series of articles highlighting reasons why we need a new model for anti-virus and security solutions.
Reason #2: the Desktop Security Software Risks
The risks of placing software on the desktop are such that I will be breaking this article into two parts.
There are many advantages to putting security and anti-virus software on the desktop. They range from efficiency to money. Under previous ways of thinking if I can capture security and virus problems at the desktop I can prevent them from going any farther. That works well in a non-connected environment. In the connected environment it makes more sense to centralize the software and monitor connections in and out. Basically "firewall" all the appliances from each other.
In a previous article we discussed the security risks inherent with desktop software designed to be the protection layer between you and all those bad people out there on the Internet. Here now we will discuss some more mundane issues regarding the risks of putting security software on the desktop:

LED Lighting Modules: Taking The Heat Out Of The Situation

LED Lighting Modules: Taking The Heat Out Of The Situation
by: James Stratford
The appeal of using LEDs in lighting applications is growing rapidly. The numerous and significant benefits of using modules that incorporate a matrix of LEDs are being recognized by design engineers in several key industry sectors, including aerospace, architectural lighting, and the “golden egg” automotive market.
Attributes such as design flexibility, low power consumption, even and reliable light, and long lifetime distinguish LED modules from designs based on traditional filament lamps and fluorescent tubes. LEDs can also have knock-on benefits, such as greatly reducing the size and complexity of the module and simplifying the lens design.
A good example of some other benefits of LED lighting is demonstrated by an application in the cabin of a passenger aircraft. A retrofit LED unit that replaced a fluorescent-tube lighting module enabled finely controlled dimming and also provided mood lighting through the use of differently coloured LEDs.
Thermal management
Perhaps the most challenging issue when realizing a module design that uses LEDs is to manage the temperature of individual device junctions during normal operation. If the considerable amount of heat produced by all the devices in a module is not managed correctly then the junction temperatures may reach a level where the LEDs’ expected life is shortened and reliability is compromised (see Links).

The Latest Technology, Wifi And Digital Cameras
by: George Williams
We were all use to the idea of sending in our film for developing and waiting for our pictures to come back. It takes days before we can see those developed photos.
Then along came digital cameras and the world was taken by storm with this cool new technology. Suddenly you could take a picture and see the results immediately. At first these cameras were slow and not such great quality but still kind of cool. Then things heated up and now we have fantastic digital cameras of all sizes and shapes that can take wonderful images which can be shared instantly with your family, or the rest of the world for that matter.
The latest now in technology integration is WiFi and digital cameras. No need to even plug your camera memory card into a computer, or a printer at all. Now you can buy a digital camera that transmits the images via wireless technology. Yes, that is right, a wireless connection for your image uploads.
