I want to tell you the story of a law school student whose dissertation was about money laundering. She often used to Google the term to come up with a useful list of Internet references. This proved to be useful to her and the whole procedure of writing her paper became easier for it. After a few months, she came across several problems like being sent to a page which was totally unrelated to money laundering every time she typed in that search term.

At first, she thought it was just a hiccup in the Internet system and then she rationalized that maybe it was a difficulty with the search engine she is using, but the continual recurrence of the problem, made her consider that she had picked up a virus of some sort. We all detest people bugging us, but people we can ward of.

What this law student was faced with was a computer bug that she could not ward off on her own. In the first place, she was not a technologically-savvy person and in the second place she never used her laptop for anything other than academic study and the actual writing of her papers.

The situation above is not an unusual issue. There are many people who find themselves caught up in technological problems that are mystifying, but which can actually be described in two words: spyware and adware. The infamous term ‘spyware’ was first coined in the year 1995 but it was popularized in the year 2000. Spyware is computer software smuggled into a personal computer in order to get hold of the personal information of the user.

This is done by capturing your keystrokes, web browsing history and even scanning the user?s hard drive. It may sound like something you see in James Bond films, but that is wrong because anyone can become a victim of spyware. Spyware can be utilized to spy on criminals because it is helpful to society, but how what about the use of spyware to seize credit card details and the like?

What people can do to guard themselves is to block spyware and other software like it such as adware and malware. This can be achieved quite simply by deploying an adware and spyware blocker. The function of these blocking programs include clearing or disabling existing spyware or to inhibit the installation of these malevolent programs.

Spyware, adware and malware are not like viruses or worms that replicate themselves, but they cause just as much aggravation because they disturb your computer’s activities. One of the most common nuisances caused by these programs is the slowing down of the computer which is very exasperating.

In some infections, spyware is not even evident as the cause of the problem. Therefore, it is best to have a blocker set up on your computer to prevent the infection in the first place. It is far easier to prevent than cure and it is also far better to be safe than sorry

If your pet is likely to wander far from home then you should think about putting an identity tag on it. The ID tag can be as simple as you want, but the most modern technique is to use ‘radio frequency identification’ or an RFID tag.

If you have a very young cat or dog, there is perhaps no necessity to tag it yet, but as the animal gets older, ID tags can become critical. If your pet gets lost, anyone finding it can then return it. If you have a cat or a dog, then a straightforward collar might be enough.

Some collars have a metal tag attached to them so that you can have your address or phone number etched on it, others have a ring, so that you can affix a small canister with your details inside it. Some just write their address on the underside of the collar with a felt tipped pen or a marker pen. This is more risky though because you may not be aware if it rubs off.

It is necessary to think about water damage if you are ID tagging a dog. Cats try to stay out of water, rain and snow, but most dogs love playing in it. If your dog’s tag is not waterproof, it will soon become impossible to read. On the other hand, cats often lose their collars.

If your pet is a horse, then it is simpler to have it branded and the brand indexed, so that anyone locating your lost horse can reference the brand and discover your contact details. If your pet is a tortoise, then you can write your phone number around the edge of its shell in a non-toxic fluid like nail varnish, but keep it small or you may poison the animal. Birds can have leg bands fitted. These leg rings have a unique number which can be looked up like a brand.

These are the conventional ways of ID tagging your pets, but the most modern method is to RFID tags them. These RFID tags can be affixed in several different ways. The simplest way is to have a plastic passive RFID tag made up and hang it from your pet’s collar. This works well, until your pet loses its collar or unless someone removes it in order to take your pet.

Another way of attaching an RFID tag, is to have your details imprinted on a chip and have the chip inserted under your pet’s skin by a vet. Some people are disgusted by this idea others do not mind. However, it does not hurt, is not uncomfortable and cannot be lost.

When the police or the pound officials are handed a stray, they scan it for a chip as part of their routine these days. Even people have them installed so that they can move across international borders more rapidly.

The RFID tag is read by a scanner and can be read from distances of several feet to several hundred yards, which makes locating a lost pet a much simpler task if it has an RFID tag fitted.

Digital cameras usually have a zoom capability built into them and better digital cameras have two zoom facilities. These are called optical zoom and digital zoom. The two ways of zooming operate in different ways and the novice frequently finds the difference confusing. In this piece, we will examine the two kinds and discuss the benefits or otherwise of them.

The first thing to realize is that the optical zoom is a physical product. It is similar to using a telescope. The lens actually moves and makes the picture appear nearer.

It magnifies the picture without decreasing the quality of that photo. It is the same mechanism that you used to get on expensive 35 mm SLR cameras.

The optical zoom is the zoom that you would like for your camera and the stronger the zoom the better. The power of the optical zoom is normally expressed as a number such as ‘x5′. If you have an expensive digital SLR (DSLR) or digital single-lens reflex camera, you will be able to swap the standard lens for a telephoto lens and get far more optical zoom – at a cost. Additional lenses are expensive, but much better.

A digital zoom is a completely different idea. A digital zoom is an electrical enhancement and is comparable to holding a powerful magnifying glass over a developed, printed image.

Test it with a newspaper photograph, the results are pretty disappointing. However, the things that determine how well digital zoom works are: resolution and strength of zoom.

The higher the resolution of the image, which is measured in megapixels, the more digital zoom you may apply to the photograph without losing too much photo quality.

Digital zoom may become applied on board the camera or later in a photograph manipulation program, unlike optical zoom which can only be done through the camera’s lens.

Some camera manufacturers attempt to blur the difference between these zoom functions by quoting ‘total zoom. Total zoom may be x10, which sounds fantastic until you wade through the instruction manual to find out that the camera has x8 digital zoom and x2 optical zoom. Do not trust total zoom figures without being able to break them down into the component types.

In fact, it is best to turn digital zoom off, because it is often an automatic extension to optical zoom. So, for example, you are applying zoom to a shot, but if you accidentally pass the OZ capabilities of your camera, it will apply DZ and that could spoil your photo.

Turning DZ off does not mean that you can’t use it. Digital cameras come with picture manipulation software, so if you would like to use DZ, load your pictures into the computer program and improve them from there.

The capabilities available within the program are far better than those on board the camera anyway and you can keep the original photograph as well

The usage of RFID tags has been picking up speed for a number of years, but 2010 has increased proliferation for three key reasons: 1] cheaper equipment and tags, 2] increased dependability and performance (up to 99.9% accurate now); 3] the agreement of an international standard for UHF passive tags.

Cost has always been a prohibiting factor, but a Korean company has declared that it will have passive RFID tags for sale for about three US cents each by the closing stages of 2011

Historically, the biggest user of RFID tags was and still is the US Department of Defense. The armed forces use smart tags to track the containers of their hardware and sometimes individual pieces of hardware too. The aviation industry has also been using them worldwide for a long time.

The latest industries to find a use for the passive tags are financial services for IT asset tracking and health care, where more than 60% of the top medical apparatus companies are using passive UHF RFID in 2010.

Companies that have not come up with a reliable system to track their stock and know exactly what they have of everything that they sell tend to carry excess levels of stock to ensure they can supply their customers’ requirements.

If you can reduce excess stock by using improved information, you can: reduce investment, storage space, labour costs; and expand asset utilization, boost stock turnover, facilitate faster billing cycles, all of which will considerably contribute to cash flow.

In short, the usage of RFID:

1] Facilitates stock control and item location in real time, which reduces product search time, lowers inventory levels and enhances control of the manufacturing process. 2] Enhances compliance, enhances work-in-progress (WIP) productivity and cuts the cost of the finished goods. 3] Enables the real-time monitoring of production, order fulfillment, and distribution processes and their level of effectiveness. 4] Improves profitably and ability to meet demand rapidly and reduces inventory costs. 5] Lowers labour costs by getting rid of manual procedures. 6] order and shipping accuracy by helping to ensure that orders are dispatched complete, error-free, and on time, which thereby raises customer satisfaction and the likelihood of return orders. 7] Provides extremely accurate real-time data capture by means of warehouse management systems (WMS) and enterprise resource planning (ERP) systems.

The way forward is to begin with the goods-in bay. Goods arrive with shipping labels, but they are often inadequate in quality and information. It would be best to create a new ‘identity badge’ for all goods received at this point. All the pertinent information that you have on the items delivered can be put of an RFID tag and attached to the pallet, the crate or even the goods themselves.

Now these articles can be added to stock and the computer will always be able to divulge what the items are in the box, how many of them there are and where they are located in the warehouse.

The simple procedure of creating an RFID tag at the unloading bay and attaching it to the items received can save hours of time wasted checking up on stock levels and thousands of dollars wasted in overstocking.
