If you are fascinated by spies and their high tech gadgets which we could see in the movies, you should be pleased to know that nowadays, you can use a spy camera yourself. The even better part is that whether you want it concealed in a hat, in eyeglasses or in a button, you can have it your way.
This is because spy cameras are getting more popular. The pinhole sized cameras that once amazed people would now be easily available on camera phones or on laptop webcams and if you can have it in cameras and phones, you can also have it in virtually anything you can think of and with that, you can use it in whatever way you can granting that you don't do anything unethical.
The Evolution Of The Spy Camera
Since the concept of hidden spy cam is quite fascinating, people commonly think of it as an exclusive item that is only limited to spies. The idea of hidden spy cameras is not very new and it dates back to 1917 wherein people would attach mini cameras to pigeons while the birds would fly around and constantly take pictures. During this time, the only ones who are able to do this were the ones who can afford a lot.
Nowadays, we could just laugh at the idea that people once used to attach cameras to pigeons as spy cameras. These devices have become so affordable that most of us would already have it. To have it concealed in an object that you could use for spying however is not that common but fortunately, you can still have it.
Even through a brief browse in the internet, you should be able to find some hidden spy cameras, some would come in a teddy bear of which you can put in your kids room or in wristwatches of which you can take videos while pretending to check time.
Some Options To Choose From
Yes, you can have your cake and eat it especially when it comes to choosing spy cameras. Of all options, one of the most ideal is the spy camera that would be concealed in the nose part of eyeglasses. This type of spy camera would sell from $400 to around $4000 and can easily be found if you search it over in the internet.
These are very pleasing devices as they can take very clear videos of what you can actually see. They also look just like ordinary eyeglasses, barely distinguishable from the ones that do not have cameras in them. These are powered by strong batteries that can last up to 2 hours of continuous operation. These are also wireless, meaning that they operate without any wires at all.
This type of spy cameras is just one of the many options you have. Whether you are buying it to spy on something or the idea of it just fancies you, you are sure to be delighted with what it can provide you. It works so well and it surely looks like something they actually use in the movies.
Hidden spy cams is perfect for unobtrusively monitoring people you want to keep your eye on. Spy cameras come in different shapes and design, such as the modern wireless spy cam that is a great way to stay hidden in the background while keep track of everything around you.

Data Correction and Cleansing Mechanisms
Introduction
One of the most overlooked issues during system implementations is data cleanup. Before going live with a new system, it's almost always wise to cleanse, fix, and consolidate data from the legacy system.
It's both really hard and pretty naive to look at fixing enterprise data in a vacuum. So, let's consider people, process, and technology together.
It is often the role of the consultant to identify potential or probable duplicates during a project. Whether using any number of specialized data cleanup tools or stalwarts such as Microsoft Access or Excel, I have found that it's typically not terribly difficult to identify potential duplicates--i.e., questionable records. The key word here is "potential", as many records need to be manually examined in order to consolidate, purge, or retire.
However, identification is simply the first step in the process--and often the easiest. After isolating suspect records, they must be investigated and ultimately fixed. Here's where it's usually a good idea to stop using phrases such as "not terribly difficult."
Some people become defensive when presented with data errors. Generally speaking, I try to say very innocently that "someone may have done something wrong." I find that it's much less confrontational than pointing a finger. Often, end-users are quick to plead ignorance or blame predecessors for mistakes. In the event that they themselves have made the mistakes (audit trails are pretty hard to dispute), the tone of the conversation is quite different. There's usually a reason that an end-user did what s/he did.
It's the client's role to ultimately make the final call on what to do with suspect records. Far too often, however, end-users do not have the time, desire, or skill set to make these calls. (See my post last month on the different focuses on consultants and end-users.) Failure to address data issues in a timely manner typically causes many problems, from cascaded delays on other project tasks to incomplete testing.
Conclusion
Sometimes on IT projects vendors during the sales cycle (and project managers during the engagement) underestimate the amount of time required to clean up key enterprise information. Technology helps in conducting this imperative exercise but is no panacea for sloppy data that needs to be cleansed.
With more than a decade of experience, Phil Simon assists organizations in all phases of systems consulting including vendor selection, project management, business needs analysis, gap analysis, system testing and design, end-user training, interface and custom report development, and documentation. The result: providing his clients with superior systems, increased ROI, and a healthier bottom line.

Resurrect Old Laptops (And Desktop PCs) With Linux
A customer came to me with a low-mileage 1999 vintage laptop which she wished to use for occasional web browsing. (Laptop specs: Dell Inspiron 3500. 333 MHz CPU, 64 MB Ram, 4.7 GB disk. Every spec was about one-tenth of today's PCs!). It was running Windows 98 Second Edition. Microsoft stopped providing Windows 98 updates years ago, and Windows 98 is now very vulnerable to attack. Worse, today's anti-virus and anti-spyware programs won't run on it. Shouldn't she just scrap the laptop?
Since the laptop was in like-new condition, we decided to extend its life by injecting some 21st century blood into it. We topped up its memory slots with the maximum RAM (a mere 256 MB!) and replaced Windows 98 with Xubuntu 8.10. It's not Microsoft Windows, but to a user it appears similar, and includes a word processor, spreadsheet, graphics / photo editor, and Mozilla Firefox web browser. I've not been able to get its onboard soundcard to work, but everything else works. There are three big upsides to any Linux-based desktop operating system when compared to MS Windows:
* It frees the user from constantly worrying about Windows Updates to patch vulnerabilties
* No anti-virus or anti-spyware programs are needed (Yay! )
* There are no Windows licensing headaches.
A potential downside is that Windows applications won't run on Linux without the assistance of either Wine or running a copy of Windows XP within a virtual machine. If you have a tired desktop or laptop PC -- especially one without a legitimate Windows license -- consider breathing new life into it with some form of Linux.
Most are available for free, such as http://www.xubuntu.org/ I tried Damn Small Linux (too minimal for this case), Puppy Linux (it was okay, but just barely), and Xubuntu 8.04, 8.10, and 9.04. Xubuntu 9.04 added some features but did something to slow response to user inputs. I settled on Xubuntu 8.10. (Xubuntu imposes a lighter load on the hardware than Ubuntu because it has a leaner desktop.) You can first just boot with the Xubuntu (or Ubuntu) Live CD, to see whether it's acceptable and runs okay on your hardware. (Of course it'll be slow when booting off the CD-ROM drive.) If so, you can install it on your hard drive from the same CD-ROM. Oh -- one caveat: Xubuntu and its siblings may not install without problems on all hardware. I'm now fighting to get it to install on a 1.1 GHz AMD Athlon desktop PC -- I have no idea why it won't install on this system, yet it installed with almost no problems on the old laptop. Let me know of your Linux adventures, please.

Critical Steps to Protect You and Your Computer on the Internet
As long as our world is evolving and the internet area is rising many threats are knocking at our computer door! Not only but also the internet scam can have multiple aspects, it can be sustained by a simple software which is hosted by your PC or even more the social network by itself structure can draw you to an expected road! Furthermore many mails lists are claimed to be unsolicited and they are so invasive in that way we cannot figure out which one is genuine or which one represents the real sender!
The web entirely can be so tricky -an unleashed tiger i can say which eats your thoughts! you are coming there but at least you don't know where you really are or where you really wanted to be. Also many widgets are posted to many websites which draw your attention with an obtrusive goal: only to be noticed or to be clicked at request. This is a critical time when anybody wants to make money using any way.
The computer intelligence offers you the possibility to express your feelings and to be more precisely to socialize with the others and to interact definitely with them.I have to recognize that nowadays is a common way to socialize with the others. As a skilled programmer you can code a complicated software !You can be really an innovator! But now comes the question: who is and for what goals does this fellow creates codes.Many of them are dedicated to this job and they are successful in this area but some of them proves to be a felon of this virtual world ! They are our enemy indeed...
Take care and surf safe

Webcam of My Laptop Will Not Function Or the Webcam Does Not Work
This problem can occur due to various reasons, some of them include, corrupted webcam application or software, corrupted webcam drivers, etc.
Resolution
Test your webcam with a new webcam application (you may try with Yahoo Messenger, Skype, Windows Live Messenger, Quick play, Youcam, etc)
Check if the webcam works with the new application.
If the webcam works well with the newly installed application, then the problem could be with the built - in webcam application or with the one that you have been using earlier.
Uninstall your previous application (the one with which the webcam did not work) and reinstall it.
Check now, if your webcam works.
If the webcam does not work, use the one with which your webcam works.
If the webcam does not work with any of the applications or software, then the problem could be with the corrupted webcam drivers.
Press and hold Windows Key and break key simultaneously.
In the System Properties window, select Hardware tab and click on Device Manager.
Click on "+" sign next to Imaging Device and check for any yellow exclamation mark beside the webcam device, if there is a mark, then it indicates that the device is in bad condition.
The device may function even at this situation but also can fail sometimes.
If you don't find any exclamation sign next to the device, then follow the below steps to isolate the problem.
Reinstall the webcam drivers from Recovery CDs or from the Recovery Partition in the notebook.
Just check now if your webcam works.
Also test the issue by reinstalling the new drivers from the webcam support link and if you are using the webcam application that came with your notebook then visit your notebook support website and in the drivers page you will be able to find the recently released webcam drivers.
After reinstalling or installing the new drivers check for the problem.
Ensure that the Startup type of Windows Image Acquisition (WIA) service is set to Automatic, if not set it to Automatic. WIA is a service that is required for running the webcam applications in the system and needs to enabled.
You can do this from Services, click on Windows key and R simultaneously to open the Run window.
Type services.msc in Run window and click on OK.
Now in the Services window, scroll down to Windows Image Acquisition (WIA) service and check its Startup type. If it is not set to Automatic, then double click on the service and set it as Automatic (beside Startup type) and click on "Start" to start the service and click on Apply. Click OK.
Check if your webcam works now.
If the problem still persists, then the issue could be due to an internal webcam hardware problem.
Before concluding if the problem is related to hardware, please check in your notebook support website for any diagnostic tools that you can run to fix these issues and sometimes you might have to be online to perform these diagnostic tests.
If you are running Vista in your notebook, ensure that it is Vista Service Pack 1.
If not, upgrade to Vista Service Pack 1 since it comes with a new webcam driver which is like a hotfix to the one in Vista.
To upgrade from Vista to Vista Service Pack 1:
Please visit the below weblink from where you can update or download it:
http://www.microsoft.com/downloads/details.aspx?FamilyID=b0c7136d-5ebb-413b-89c9-cb3d06d12674&displaylang=en
The webcam may not work even when your system resumes from Hibernation or Standby mode. This happens because most of the video applications could not adjust to the change in the Power State of the system.
To resolve this problem, restart your webcam.
If restarting will not resolve the problem then restart your computer which will resolve the issue.
The general procedures have been mentioned, there might be few more steps that have to be followed to isolate the problem. Please contact your support for this.

Living in the Computer Age
Saying that the world has come a long way since the advent of the computer is a vast understatement and though no one questions the distance we've all come, some, including myself, wonder about the direction.
It is a staggeringly different world than when I was young and in school and striving to get my speed up to 80 words per minute on an electric typewriter. So much of the progress that has come about as a result of the electronic infiltration of our world has been good but a high price has been paid in many areas. True, people are able to get specific information at the touch of a fingertip that would have been difficult or at least much more time consuming to acquire at an earlier time. Students are able to accomplish a lot more than ever before and people can handle much heavier workloads with the aid of a computer, however, what has been gained in accessibility and speed has been greatly compromised by a loss of personal interaction and decline of human relationships.
It's sad to see young people glued to their computer screens for hour after hour playing action games instead of being involved personally with other young people. They lose a lot of the valuable experience of forming friendships and relationships that can be such an asset to their lives. Many of the youth of today are not nearly as well rounded as those of earlier times and often are not as healthy as they spend too much time sitting and staring at a monitor rather than moving and using their bodies. Being overweight is a significant problem with a high percentage of our young people now and is a direct result of too much inactivity along with a high fat, low nutrient based diet.
The same is true for a large number of adults who are less active and in worse physical shape now than ever before. Moderation can be a great ally in most areas of our lives. We should use what is available and take advantage of improved techniques and modern conveniences without being consumed by them. It's hard to find the correct balance but it is important to keep working at it. Pulling back when you're in the midst of a whirlwind of tasks to be completed and problems to be addressed and looking again at the big picture helps to keep the right perspective. Paying proper attention to the things that are the most important to us is critical. At a recent commencement ceremony for the graduates of the University of Pennsylvania, the special guest speaker was Eric Schmidt, the Chairman and Ceo of Google. He had this to say to the graduates; "turn off your computer. You're actually going to have to turn off your phone and discover all that is human around us. Nothing beats holding the hand of your grandchild as he walks his first steps".
In those two sentences lie a profound truth and volumes of wisdom. Mankind has been intelligent enough to invent amazingly efficient machines that can be an enormous aid to our lives. Let's hope it's also intelligent enough not to let those machines jeopardize or take the place of what is or should be paramount in our lives.

How Do You Determine the Right Wide Area Network (WAN) Architecture For a Computer Network?
One of the most complicated decisions to make for an IT department concerns the architecture for a multi-site voice/data network. Should the network be based on simple T1 point-to-point bandwidth circuits? How about burstable DS3 bandwidth or maybe a single OC3 bandwidth cloud? No matter the bandwidth chosen .... the most efficient design should base the communication backbone on a MPLS configuration (Multi-Protocol Label Switching).
To get there, first and foremost in deciding about the WAN architecture of any organization communication network you must determine ....
- How many locations you would like to connect?
- Architecture - hub and spoke or mesh architecture?
- What applications would be run on this network .... Voice, Video, Data, all of the above?
- Precisely which applications will be run in case of Data?
- What will be the % each will take up of your QoS, the total of all three should be 100%?
- Voice is the premium level QoS and hence the most expensive as it is a real time communication, followed by video and then data.
- How many users precisely will be using the network at a given point of time at each location?
- What will be the concurrency factor? Are you are looking for 100% concurrency or you can manage with lesser concurrency?
- What is the scope of scalability at each location and hub location?
- Will the access to internet also be given to users?
- Internet at a central location can help you in implementing and enforcing various security policies of your organization.
- Do you want to give access to the network resources to a mobile user?
The answer to all these questions will help in arriving at the MPLS bandwidth required at each hub and spoke location.
Honestly speaking no organization should ideally try to do this calculation themselves. Instead they can hire a consultant or a telecom service provider to do this activity as they are experts in designing this solution. With their help you can easily decide upon the bandwidth for each location, select suitable router, make redundancy plans, routing the traffic on Atlantic or pacific routes, blah blah.
For help walking through the analysis .... and determining the best solution .... take advantage of the free help at DS3-Bandwidth.com.
Ideally I also recommend to give the freedom of providing and managing the routers at each location to the Telecom service provider. Then it becomes a managed solution and the service provider can easily monitor your network in the event of an outage. They then can remotely login into the routers and manage your complete network giving you higher uptimes and SLAs.
In the end .... take a deep breath and work through the steps above. Following this simple game plan will get you to the right decision for your organizations network architecture.

- What will be the % each will take up of your QoS, the total of all three should be 100%?
- Voice is the premium level QoS and hence the most expensive as it is a real time communication, followed by video and then data.
- How many users precisely will be using the network at a given point of time at each location?
- What will be the concurrency factor? Are you are looking for 100% concurrency or you can manage with lesser concurrency?
- What is the scope of scalability at each location and hub location?
- Will the access to internet also be given to users?
- Internet at a central location can help you in implementing and enforcing various security policies of your organization.
- Do you want to give access to the network resources to a mobile user?
The answer to all these questions will help in arriving at the MPLS bandwidth required at each hub and spoke location.
Honestly speaking no organization should ideally try to do this calculation themselves. Instead they can hire a consultant or a telecom service provider to do this activity as they are experts in designing this solution. With their help you can easily decide upon the bandwidth for each location, select suitable router, make redundancy plans, routing the traffic on Atlantic or pacific routes, blah blah.
For help walking through the analysis .... and determining the best solution .... take advantage of the free help at DS3-Bandwidth.com.
Ideally I also recommend to give the freedom of providing and managing the routers at each location to the Telecom service provider. Then it becomes a managed solution and the service provider can easily monitor your network in the event of an outage. They then can remotely login into the routers and manage your complete network giving you higher uptimes and SLAs.
In the end .... take a deep breath and work through the steps above. Following this simple game plan will get you to the right decision for your organizations network architecture.

IP Cameras and Airport Surveillance
Airports are one of the most congested areas at any given time. Furthermore, in light of the recent events it's apparent that they need more security than ever before. Airports have a lot to manage when it comes to security and safety as people are constantly coming and going. IP cameras can record all the action at any given time.
Advantages of IP Cameras in Airport Terminals
- With IP cameras you get the benefit of real time surveillance directly to any place over the internet. What this means is operators can watch baggage claims, check-ins and other hazardous areas from all over the world including police stations, customs rooms and fire and medic aids. This real time remote surveillance offered with IP cameras is something no airport should be without.
- IP cameras can also keep surveillance on all illegal activity including drug smuggling and terrorism. It can record on command through motion detectors and upload video directly to the internet. For investigative searches and evidence, this is a critical feature. IP cameras store and record the information in digital form which offers almost unlimited storage space.
- Another benefit to IP cameras is that they are scalable meaning they can grow with the airport.
- Furthermore, IP cameras can be set up as wireless cameras which offer lower installation costs as well as covert video surveillance.
- Finally, IP cameras work with intelligence technology that allows them to record on motion as well as recognise suspicious individuals. This may seem hard to believe but IP cameras can actually use facial recognition and other algorithms to seek out illegal activity and record immediately. This is done using a technology called Video Analytics and Facial Recognition Software.
- However, it's important to keep in mind that IP cameras should not be substituted for actual guards and security team members. An over reliance on any video surveillance should never replace human security. Instead, it's important to incorporate both people and IP cameras in your surveillance strategy.
Tips for Successful IP Camera Surveillance Set Up
- Look to the trends of the past to determine where criminal activity has taken place.
- Work with the current airport security systems that are already set up. Perhaps re-installation is not necessary in some instances.
- Consider the security personnel that work the airport- where are there usually hidden spots? Where are the blind spots in the airport?
- Look to the past trends to determine which airports should be considered high risk in terms of drugs and terrorism. This should be targeted with IP cameras.
- Make sure you position cameras at all entrances and exits of the airport as well as outside the terminal and in places that link to trams or trains. Illegal activity often takes place outside the terminal on the various transportations.
- Consider the rush hour times for the airport.
- Monitor all open areas as well as constant surveillance on the planes and equipment.
- Finally, make sure you include cameras in restricted areas. Authorized personnel may be a threat in airport situations as well.

Background to the Computer Technology That We See All Around Us Today
From the beginning of time, man realised that he needed to take stock of his possessions in order to make informed decisions and be in control of his environment. His possessions were not many, a few goats or sheep, a dog, two spears and an axe, maybe a few wives and an increasing number of children. Now the only computing equipment at his disposal then was his ten fingers and ten toes, but the word ten, or one, did not exist in his vocabulary. He would allocate one finger to each goat, one to each rabbit he caught, and so on. Now, the fingers and toes allocated to the rabbits and goats were easy to deal with but had their own problems because it was difficult to remember which fingers or toes had been used to represent something, and which ones were still unallocated.
And as the number of goats increased beyond his ten fingers and his ten toes, he found himself in a serious computational dilemma. Computer people today call this an overflow - memory size exceeded. Our resourceful ancient ancestor quickly found a way around this problem by resorting to the use of sticks and stones to extend the capacity of his computing system. That turned out to be a stroke of genius because that is when rules governing addition and subtraction of digits became clearly defined. When a new goat is born, put one more stone to the pile of stones, when a new lamb is born, put one more stick to the pile of sticks. When the ancestor, or a jackal, ate one sheep he removed one stick; and when he decided to eat all his goats, he would throw away all his stones after eating, not before, to avoid confusion. Nothing could be more elegant. Much later, mathematicians discovered that they could also use this process and called it addition and subtraction.
These sticks and stones form the building blocks of a computer as we know it today. The same sticks and stones that our ancestors used several thousands of years ago are still there, miniaturised and disguised as integrated circuits, inside the modern computer. Our ancient man, who used to shuffle his sticks and stones as he carried out his calculations, is also still there inside the modern computer, reduced to some operating system and application software.
So really, nothing much has changed since the beginning of time, except of course the fact that whereas the sticks and stones technology was available for free, modern technology, like everything else, is not so free. My next few articles will trace the stages in computer technology development from the Stone Age to the present.
Meanwhile, you can visit this Home and Office Technology Shop to see what the present holds for you.

How to Get Someone You Know Switch to Macintosh
If a Mac is so great why doesn't more people use them? Almost everyone I know are happily using Windows not knowing what they are missing. Often they ask me: why are you using that Mac? I get this question from time to time and I have developed a good routine in how to answer those questions. You want to know how I confront this?
First I tell them that I use a Mac because I like it and it suit my needs perfectly. And then I do not give them anymore. Sometimes they say OK and move on with their life. If that is the case it is OK. You do not have to defend what you like for anyone, that is your choice alone.
Other times they start asking questions and these questions I try to answer as honestly as possible. If I sense more interest from the person I usually start demonstrating a feature I like with Mac OS X. This can spark more questions from the subject and eventually get the snowball running.
As a person I am not the one that likes being subjected to sales pitch. And therefore I try to keep the same attitude when I need to speak to others about a product I like. Sometimes the person asking you questions actually expect sales pitch from you. Prove them wrong! This can also spark some interest because your answer is unexpected. It is not sales pitch.
If someone asks me what kind of problems I have had with my Macs I am honest there too. For example I had a bad battery once, Apple replaced that battery without question. If you keep being dead honest it will be easier for you to convince users to switch. In the end it is about what I like, not what others like me to use.

Checking Your Email
How much is too much when it comes to checking your email? For many of us, we have multiple email accounts, which means that we have to check them multiple times each day- especially if most of our business is conducted online. For instance, whenever I am on the computer, I always have my main email account open in a tab on my web browser so that I can see when any new email comes in. It seems that anytime I'm not looking at my email, I receive a bunch of emails. But is there a limit on how often you should check your email so that it's not viewed as an obsession?
If you ask most people, it seems like you can't get one really solid answer on how much is too much when it comes to checking your email. A lawyer might check his email twenty times a day, while a stay-at-home mom might only check her email once. It seems that something as simple as checking one's email is not easily quantified. Rather, it is contingent on the person, the person's profession and how much of that person's profession and/or personal life is conducted in the virtual sense. It almost seems as if emailing someone has replaced all other forms of communication.
Can you remember the last time that you sat down and physically hand-wrote a letter to someone? What about the last time you called someone on the phone to speak to them versus writing them an email? Is email communication breaking down other forms of communication? Some would argue that this is exactly what is happening. People no longer know how to carry a conversation. They prefer to email someone over speaking to them in person or over the phone because it is less confrontational. Their attentions can be diverted to other things as they multi-task. The same thing goes for writing a letter. People prefer email because while you can be judged for spelling and accuracy, the other person on the other end of the line can't judge you based on your handwriting if it is typed up into a neat email. Whatever your opinion, there are those of us who find that our handwriting has actually gotten worse because we never have the occasion to practice it!
Email is a great form of communication, and it is certainly cheaper than calling someone or writing them a letter. However, sometimes email can become burdensome with things such as multiple accounts and spammers. One way to attack the spam problem is to utilize the "filter" option that comes with most email accounts. Also, be wary of opening mail from people you don't know. Spammers will often disguise themselves as people you may know by using the name of a friend or by addressing you by name. In some instances, opening up spam mail can cause your computer to become infected with a computer virus- something you definitely do not want. So, beware of the spammers. The next thing is to minimize the number of email accounts you have. Most email accounts provide the option of allowing you to integrate email information from a completely different email address into the new one with no problem.

The 5 Best Computer Buys of 2009
I recently decided to buy my father a new computer (his was a dinosaur). Like most people in the market for a new computer, I wanted one that didn't cost a small fortune, but was still good. What I found was quite a bit of stress and a LOT of hype. Everyone claims to be the best for your money, so how do you know if it's true or not without being a computer genius? So I decided to write this article with the hopes of saving you some time and tears when searching for the perfect computer. It is a simple list of my pick for the top 5 best computer buys of 2009.
Please note that I am not a computer guru and this was not written for computer gurus. It is a quick overview for the average Joe. There are some spec for each computer, and a link in my bio to find out more information about each model if you desire.
5. HP Pavilion s3500f Desktop
HP has always been a trusted favorite of mine. The Pavilion is a well-established product, and for good reason. This particular model comes with:
-AMD Sempron
-4GB DDR2 SDRAM memory
-a 500GB hard drive
-Windows Vista Home Basic 32 bit
-and a whole lot more.
It's a great computer for home use and is an excellent deal.
4.Acer Aspire M3201
Acer is a brand I personally have not owned before. However, the brand gets great reviews and the prices are unbeatable. I've been hearing nothing but good things about it from friends and family members that own Acer computers, as well as the professionals. This particular model has:
-AMD Athlon processor
-3GB DDR2 SDRAM
-320GB Hard Drive
-and Windows Vista Home Premium 32 bit
3. Gateway DX4200-11
I think that the greatest thing about this computer is simply that it is backed by Gateway. They've always been very good with technical support and customer service for their products. I've always had very happy dealings with Gateway. The computer is a bit higher in price, but comes with:
-AMD® X-4 Quad-Core Processor
-6GB DDR2
-a 750GB hard drive (750 GB makes my head spin!)
-and Windows Vista Home Premium 64 bit
2.Acer Aspire X3200 Desktop
Yes, another Acer. You can tell that I fell in love with this brand pretty quickly. This model is actually the one I finally decided to buy for my father. It comes with:
-AMD Athalon processor
-4GB DDR2 SDRAM
-500GB hard drive
-and Windows Vista Home Premium 64 bit
The price is slightly higher than the other Acer listed, but the upgrade was well worth it for me. My father went from having a dinosaur to having a computer twice as good as mine!
1. Apple iMac Intel Core 2 Duo 24" Desktop
This is actually the computer I've been eyeing for myself recently (Don't tell my dad). A few months ago a friend of mine got one and every time I go to her place I ask to use it! It's quite a joy. I just fight with myself over the price tag and whether or not I truly want to switch to Mac. This is at the top of my list because it's the best. If you are in the market to pay this much for a new computer, this should be the one!
-Intel Core Duo processor
-3GB DDR2, 320GB hard drive
-Mac OS X v10.5 Leopard
-24' flat LCD screen monitor
This is my personal pick for the top 5 best computer buys based on the research I went through. Hope it saves some of you time and money!

Eye Strain at the Computer
We've all been there. At some point or another, you've probably sat down too long at your computer. You know when this is the case because your eyes are straining to read the letters on the screen, and every time you look away, you begin to see spots that really don't exist. Eye strain is becoming more of an issue for many of us because the majority of our work nowadays revolves around a computer screen.
From checking emails to ordering things online, computers are a fixture in our lives. I no longer worry about the power going out for fear of not having the lights work; rather, I fear the power going out because there's a good chance that my computer won't work! If you find yourself at the computer, it is easy to become totally engrossed in something to the point where you sacrifice all bathroom breaks and meals. Don't allow this to happen. Instead, to prevent eye strain (as well as other problems), make it a point to get up at least once or twice every hour if for nothing else but to stretch your legs. If you are engrossed in something that needs your absolute attention, then little things such as looking away from the screen briefly can work wonders for your eyes.
People take for granted how often they use their eyes for things as small as typing. When I type, for instance, because I know where all the letters are on the keyboard, I can often type without having to even look at the computer screen except to check for errors every now and then. This gives my eyes a break from staring at a screen for long periods of time. Additionally, if you are using a computer, another thing that can help reduce eye strain is reducing the brightness of your screen.
When you are working at the computer, other things to take into consideration include exterior lighting as well as desk options. For instance, do you work in an office that has fluorescent lights? Fluorescent lights are often insufficient for people who work at computers because of the glare as well as the harshness of the light. It's no wonder that people come away at the end of a shift or day of work complaining about having a headache. Ideally, it is best to work at a computer where there is an indirect light source. For example, a desk lamp is always a good option. Make sure that the lamp is level with the computer and is not shining in your eyes.
Regarding your work space, your make sure that your computer is sitting on a desk or surface in which the computer is at eye level with you. A computer which is set up too high or too low can cause eye strain because of how your body will be forced to adjust itself in order to clearly see the monitor. There are all sorts of ergonomic keyboards as well as screens that you can place over your computer monitor so as to reduce glare and other eye aggravators. Knowing that you have options as well as exploring those options will help you to prevent eye strain from wreaking havoc in your life.

How to Create a Letter With Microsoft Word Processor in XP Or Vista
To make a letter the most basic use of a word processor, Open your word processor by finding the icon, or looking for word processor in your programs. Once you find the word processor (usually located on the desktop) open the program.
Once you have opened the program open the word file, and choose the letter document, and then a letter wizard should open. Once it opens you can choose the letter style, and then the letter wizard will open.
When the letter wizard opens fill out all the formalities such as who it is to, from, date, etcetera. The wizard will then close. You will see where to place the body of your letter. Look for an insert key on your computer then press it, and use your mouse to put the pointer in front of the point where you wish to start your letter, just start typing until your done. Then hit insert again to turn it off. Then go through the grammar and spelling by pointing at each word that is highlighted and right click. A box will then come up that will show you how to correct your errors. In addition you can go to tools, and find your thesaurus if you need it.
To keep your letter from being generic, there is a tool bar at the top of the page with a lot of options to spruce up your letter.

Technological Advances That We Can Keep Up With
Technology has come a long way in the United States, but it seems that just when you're getting used to one new thing, another new thing is produced. Then the learning process has to start all over again. That's technology for you! For instance, I can still remember being in college and being really excited to have a computer of my own. It was a big, hulking thing that had a huge 19 inch monitor. However, it wasn't one of those computers you see nowadays. It was one of the older ones which was shaped like a giant box. Today, most new computers are sold as flat screen panels, fitting snugly into any corner. This was certainly not the case not even ten years ago. How fast things advance!
Let us turn our attention to cars. Does anyone remember a time when we didn't have cell phones? Then there came car phones. Car phones looked like regular phones, except they were in your car. They were big and bulky. This isn't the case now, however. Today, everyone has their own cell phones which come in all sorts of shapes and colors as well as sizes. Most cell phones are extremely small, though. Cell phone use has gotten to the point where some states were forced to have written rules and laws governing cell phone usage while driving on roadways. Who would've thought? To see a corded phone or even worse- a rotary phone (the one in which you have to push the numbers individually around a circle) is almost unheard of.
For many older people, technology is still a fairly new thing. For instance, just the other weekend, I found myself explaining the difference between being "on the computer" versus being "on the Internet" to my grandmother. I found myself becoming exasperated when she didn't get it after I explained it to her once. I then had to regroup and remind myself that not everyone keeps up with all of the things that go on with technology. Besides this, she is from an entirely different generation of people who didn't have computers.
Trying to keep up with technology is difficult and probably will continue to be difficult because there is always something new coming out. I'm sure that twenty years ago, people would never imagine that we'd have laptop computers, and games like Guitar Hero. The generation growing up today will look back in twenty years or so and be able to say that they didn't have certain things because they haven't been invented yet. Likewise, future generations will never know a time without certain items. Rotary phones and cable boxes will be housed in museums of artifacts from the late 1980s/early 1990s. This isn't to say that it is hopeless to try to keep up with technology; rather, it would behoove of us to be aware of the various technology that is invented. From new cell phones to new kitchen gadgets and devices for your car, it's always good to know what's out there regardless of whether or not we decide to purchase and use these items.

The Kids Are Smarter Now
Growing up is not quite the same as it used to be. It seems that kids nowadays are smarter than ever before (or at least they should be!). With so many new technological advances over the years, children who are growing up in the millennium have many more opportunities than kids who grew up in the 1980s and previously. Just the other day, I saw a little girl with what looked like a miniature laptop , except for children. I can also recall a conversation not that long ago in which my mother told me that my uncle had recently purchased a cell phone for his five-year-old daughter. Now, five year-olds know how to use cell phones?! I couldn't help but wonder who my cousin was planning on calling with that phone.
When I was in high school, cell phones weren't even in our vocabulary. Instead, everyone was obsessed with having a beeper. Now, if you ask a child what a beeper is, I'm not sure that they would know. The only people I see using beepers anymore are doctors and nurses. It's great that so many children are so technologically savvy. And the funny thing is that in most cases, you have children teaching adults (namely, their parents) how to use different gadgets. For example, my brother had to explain to my father, a lawyer, how to use his brand new iTouch. I'll never forget the response that my dad had, "Why does anyone need one of these things?"
If you stop to think about it, even such things as pay phones seem almost obsolete. I can remember a time when pay phones peppered sidewalks. Now, everyone has a cell phone. It is rare that you'll ever see someone use a pay phone. After all, who even carries change around, let alone cash? On the flipside, there are those who question all of these technological advances that have been made over the years. Some even go so far as to say that we, as a nation, are dumber now than we've ever been. Technology is supposed to help us, but in many ways it hinders us too. Today, instead of going outside to play, children are inside "exercising" to video games invented by Wii or playing computer games which are meant to enhance their minds.
What did people do prior to all of this technology; before the GPS systems, cell phones, automatic drip coffee machines and microwaved meals? Have we become slaves to technology? Will future generations know how to open a can with their hands versus an electrical appliance? Will people know what it's like to stir batter with a spoon or wisk? Some people might laugh at this, but the threat is very real, and it falls on our children's shoulders. It is great to know that technology is there as an option, but we should always be aware that there are other things besides this. It's ok to go outside for a run, to use a pay phone or to pay with cash. The world doesn't have to revolve around double AA batteries and HTML.

The Internet and Humankind
Man has since the times immemorial been a magnet for information and has struggled for improved means of communication. The modern day man for the last few centuries has tried all sorts of experiments to bridge the divides of space and time. It is true for the technological developments that the progress which in the past needed hundreds of years to come by, now is sometimes achieved in mere decades. It is quite an interesting leap of technology from the rudimentary forms of communication like the early telephone or the telegraph when we compare it to the internet revolution of the present day level.
The internet or its rudimentary form evolved about half a century ago. But it was in the 1990's that it came in vogue and received the massive approval of general masses. It has evolved at an impressive pace. The greatest appeal of internet is its easy access to a sea of information and the ease with which one can access it from the cozy environs of one's home. Not very long ago in the past one had to run about to gather information about a particular topic hectically, which consumed a lot of time and effort. Now with the advent of internet, a whole universe of information related to virtually any field including the science or of pure arts is just a click away from anyone who has the access to computer and the internet. One does not need to be net savvy to reap the benefits of this marvelous tool. Having said that, it does not necessarily mean that the internet is not a place that is out of bounds for the technical experts. They have the access to the most comprehensive technical data available to the human kind ever which is not stagnating, but is rather in a constant process of evolution every second. This fact remains another of the great appeals of the internet which indeed is a proof that the internet and its related specialties are sure to stay with the human kind in the future.
When the World Wide Web evolved in the earlier days of internet revolution, it was a new field, which was open for experimentation by all. There were not much rules to follow in the beginning. Its main use was more or less restricted by an average user to be a means of gathering information and to communicate with people across the globe. Later on with more and more people getting hooked on to the appeal of it, the internet became a subject of key importance. It not only remained a tool for information collection or to communicate to others electronically but also became an alternative option for conducting business. E-commerce is thus having an ever increasing following by an eager population to make use of this fascinating facility from the comfort of their homes. One can not only shop on line but also make reservations for flights and hotels without any difficulty through the internet.

Are You Addicted to the Internet?
In this day and age, it seems like everyone has got a problem with something. The latest and perhaps most unbelievable addiction is to the Internet. But is this really that far fetched? Many would argue that it's not. In the past few years, especially the past two to three years, more and more people have been working from home or remotely in order to earn a living. This is due, in part, to the high price of gasoline as well as the fact that the United States are facing some tough economic times. The bottom line? People are trying to save money where they can. Since the Internet came about in the 90s, people were instantly hooked. Now, you could send your friends an 'instant message' via AOL Instant Messenger, you could email your grandmother a 'thank you' for that Christmas gift, you could post pictures of your vacation on Shutterfly. It was all too good to be true.
Now, the Internet has expanded so much to the point where people can conduct their entire lives online in a virtual format. You can do your banking, book airline tickets, watch movies, upload funny videos, chat with friends via Skype and much more all with just the click of a button. The Internet has given us almost no reason to need any other source like newspapers or television or even radio to communicate information. After all, why go through all of that trouble to get out of your seat and turn the television on when you can simply catch up with the latest episode of The Tonight Show online? In many ways, the Internet has made our lives easier- perhaps too easy.
Is it any wonder then, that the Internet should be an addiction for so many? One of the first things that we do when we walk in the door is head straight for our computers to check our multiple email accounts and send a quick Twitter message out to friends. But is that really what one would classify as an "addiction"? If you find that you cannot even go a day without using the Internet for something, you may have a problem. It may not necessarily be an addiction so much as it may be a dependence on unitizing the Internet for what it is: a viable source of information.
Like anything else, we have to learn to look out for warning signs that something as simple and innocent as using the Internet doesn't turn out to be something much bigger. Often times, and just like other types of addicts, when confronted about our over-use of the computer to log onto the Internet, we'll deny that there is a problem. We'll make excuses as to why we need to use the computer saying things like, "oh, I just want to check something really quick," not realizing hours later that we've spent so much time on the Internet. In order to combat this problem, we need to force ourselves to step away from the computer, to take a break and do something else that is healthy and beneficial to our well being. Go for a walk; get outside and get some fresh air!

Help My Computer is Obsolete!
What Makes a Computer Obsolete? The answer to this question will entirely depend on who you ask. Some will tell you that your computer is obsolete the second you remove it from the store, since newer models reach store shelves regularly. Although this thought was a prevailing one years ago, most consumers now know that this is not the case and some argue for extended use of computers.
You may need to think about a new computer if:
* Your processor speed is too slow to manage the operating system you wish to run. Speedier processors will enable basic tasks, like surfing the Internet, word processing, and email.
* Your RAM is slowing you down. Most current operating systems require a minimum of 1 GB of RAM; Vista needs 2 GB.
* Your operating system limits your use of newer programs, if you require those newer programs. The error "Operating System not supported." will let you know that you've reached this point. If you do want one or more programs that are not supported by your operating system, it may be time to upgrade.
* You want to use USB peripherals and your computer doesn't have USB ports.
* You want to use the Internet or you require wireless connectivity and your current machine does not have these capabilities.
There is No Such Thing as Obsolete There a group of computer users who claim that there is no such thing as an obsolete machine. Machines that are running low on memory or RAM can be upgraded. If your needs are limited to word processing, simple games, and email, there are a wide range of machines that can effectively serve your needs. Just because increasing power is available, does not mean that your needs will be better served by investing in that power.
If your computer is only a few years old and is slowing down, there are upgrades that can keep you current:
* Consider increasing your RAM. Most computers are sold with extra slots available for RAM. If your complaint is that your machine is slow, increasing the RAM is an inexpensive and easy way to increase its speed.
* Update your security software and ensure that there are no viruses present on your machine. Operating systems and peripherals need to have their software updated regularly too. Think about it like getting an oil change for your car: your machine will run smoother and faster after these updates.
* Space is at a premium on your computer. Consider a cleanup of old files. Store files that are important on CDs, DVDs, and other storage devices. Or invest in a new hard drive; with hard drives dropping in price, this is another easy fix for your computing woes.

Accugas AGA EFM Calculator
ACCUGAS is a flow calculator for verifying electronic flow measurement (EFM) results. It computes gas volumetric, mass and energy flow from orifice meters, precision tube v-cone meters, wafer cone meters and turbine meters. It references AGA-3, AGA-8 and AGA-7 reports and McCrometer published technical papers in its calculation.
ACCUGAS is a .Net based program and is compatible with .Net framework 2.0 and newer. Most of the current windows based computers should be able to install and run the program. The minimum hardware requirement is 400MHz CPU, 96MB memory and 300MB free volume in Hard drive. The windows operating system (OS) that it supports are windows 2000 pro SP4 and newer. Microsoft .Net framework 2.0 is a must and it can be downloaded and installed at no cost through Microsoft website.
ACCUGAS includes a Graphical User Interface (GUI) for easier data access and a Dynamic Link Library (DLL) that does all the calculation. Basically the GUI parts handles the user interactions like, data input, result verifcation, program licensing, etc. The program is designed to be capable of doing calculation without the GUI once the program is licensed. In other words, the dll is callable to other applications, such as Microsoft Excel Macro (VBA), or Microsoft Visual Basic, Visual C# applications. This feature gives some advances users more flexibilities and sometimes becomes the preference over the built-in GUI.
The current version of the ACCUGAS program is 1.20. It supports latitude and elevation compensation, downstream or upstream tap locations, imperial, metric unit auto conversion and heating value calculation. AGA-3, AGA-8, AGA-7 and V-Cone intermediate results display.

You can use Windows Disk Cleanup and Disk Defragmenter programs to help you maintain you files and hard disk. These programs are located under the System Tools menu of the Accessories menu. Disk Cleanup will help removing the outdated and temporary files, while Disk Defragmenter will pack the hard disk data orderly on the hard disk to improve performance. There are more information on the web, if you decide to use these tools.
Physically cleaning the computer, monitor and keyboard will also help to maintain it in the long run. Purchase a can of compressed air to clean the hardware and monitor air vents, plus the keyboard monthly will eliminate most of the dust and food that may stick to it.

Cache Manager Causes File Loss on Windows NT Based Computers
You may come across file system corruption and file loss situations if you are using NT based version of Microsoft Windows operating system on a FAT (File Allocation Table) partition/volume or CDFS (Compact Disk File System) volume that has a file system filter driver running. In this case, you may lose your critical data, application or multimedia files and face serious data loss situations. In order to resolve such issues, you need to opt for powerful and advanced File Recovery software.
You might encounter this problem due to MDL (Memory Descriptor List) interactions between the system filter drivers, the SMB (Server Message Block) server, the Cache Manager and FAT. There is an error in Cache Manager of NT based versions of Microsoft Windows that might result into system corruption and file loss in case the below mentioned conditions are true:
Windows NT based operating system or file server (Srv.sys) is running and sharing data on local FAT system (Fastfat.sys).
Note: This issue doesn't occur if the file server is sharing data on the NTFS file system based computer. However, the issue might exist with other file systems or codes that exercise MDL (Memory Descriptor List) I/O (Input Output) in the ways similar to Srv.sys.
The Windows operating system is using the system filter drivers. The file system filter driver must be aware of Fast MDL routines and this must filter the I/O on FAT file system.
For instance, when the filter drives filters Input/Output on the SMB server that is shared on FAT system. The I/O requests, which flow from network system through server to the filter drive and into FAT partition, might result into file corruption.
Resolution
You can sort out this behavior of Microsoft Windows operating system by installing the latest version of Windows NT kernel (that includes Cache Manager). It no longer ignores the returns from filter drive, which indicates the filter didn't write data or free the MDL.
You can prevent this problem from occurring in future, but it won't solve the current issue of corruption and file loss. To fix this issue, you need to use File Recovery Software.
File Recovery Software are powerful and advanced third party tools, which thoroughly scan the whole hard drive and extract all data from it. These software come equipped with interactive and simple graphical user interface and enable you to achieve quick and safe 'Do It Yourself' File Recovery.
