Why to Avoid Discount Kitchen Carts

Nothing is worse in your kitchen than prepping for a big meal fro friends and or family and suddenly hearing a crash behind you. That noise you heard was your discount kitchen carts failing you and now all those beautifully presented pieces of gourmet delights are splattered all over the floor. And you know that no matter how big, no kitchen ever seems have enough counter space.

This is the problem with discount kitchen carts, while they may look great in the store, they may not be as good as they look when put to work in your kitchen. These carts may not have been made to hold the weight of the meal a gourmet cook makes. While they don't seem like much individually, the weight of all those ingredients adds up. It can become unbearable for a cart that is not made as well as it should be.

For the most part discount kitchen carts were not made to be use by gourmets and those who are really cooking in the kitchen. Generally those people are going to buy top of the line items to do their jobs. Instead, discount kitchen carts are often thought of as more of an accessory in the kitchen, for looks, instead of a real piece of cooking equipment.

If you aren't planning on putting a lot of weight on them, you may still think discount kitchen carts could still be an option for you. But you need to think about the other aspects of the carts as well.

What about the finish? Things look great in a store but after daily use with a cheap wood top, the surface is going to start staining. If it has laminate or a Formica top, that is going to stain or start to peel up as you clean it after uses. Metals that are not high quality stainless steel will begin to rust and stain and start to look like an old marred cookie sheet. They are just not made for real use over the long term. Who wants to be served off of a horrible looking stained kitchen cart? With discount kitchen carts once those stains set in, you'll be embarrassed to use the carts and hide them away, wasting the money you've spent.

Next, comes serving. If you have purchased discount kitchen carts you may find out why they were discounted when you go to deliver a meal. How humiliating will it be to have a cart that wobbles and bucks as you are tying to roll it up to the dining room table for serving? You will see your food splashing and flopping all over the place and the nice presentation you had planned will be ruined.

When it comes to discount kitchen carts, you often get what you pay for, a discount item that is not going to do the job you really want it to do. It's worth the little extra initial outlay to have a kitchen cart you know is durable and will help you deliver those beautiful meals to your guests. Spend a little more to get exactly what you need to make your kitchen and serving experience complete!

Back Pain - The Increasing Problem of Poor Workplace Posture of Computer Users

Those of you who regularly 'surf the net' probably know all about the minor aches and pains that can arise when using computers for long periods at a time. These back, shoulder and neck pains often seem insignificant to the user. Others subconsciously link the cause to other areas of their life such as an overindulgent exercise session, their workload or even their age, using a 'quick fix' pain relief as a solution! Age does not stimulate back pain, repetitively positioning your body in an incorrect position will. Poor posture is the cause, shoulder, neck and lower and upper back pain are the symptoms. I've noticed that most people set about easing the symptom whilst ignoring the deep rooted cause.

Most of us know that those minor chronic aches and pains can, if ignored, sometimes develop into much more serious issues that can cause a lot of pain and potentially threaten our ability to work. OK, so this isn't a dramatic risk like working on a fishing boat, down a coal-mine or in the army, but it can still be career-threatening and life-changing.

These problems are only likely to get more common. Computer use is has grown dramatically over the past decade and continues to grow, both in and out of the workplace.

I often like to point out the following - when I was growing up, extensive computer use (including gaming) was only for computer geeks, like myself. But with the advent of social networking sites even cool kids are using computers for very long periods at a time, and from much earlier ages than ever before. In fact, I visited a number nurseries the other day on a mission to find the most suitable for my baby son. I was amazed to find the amount of computers present, and the age of the children using them. I'm not talking about kids preparing for school life, boys and girls as young as 3 navigating PC's with considerable aplomb!

As impressive as such feats appear on the surface, this trend also has worrying implications. Studies of schoolchildren in Scotland and Scandinavian countries in recent years have shown that they start suffering musculoskeletal pain from an early age. Much of this is correctly concluded as down to carrying heavy schoolbags and poor school furniture, but they've also shown clear correlation between the amount of time spent using computers and experiencing pain symptoms.

The 2007 ViewSonic survey of 1500 computer workers reported 71% of respondents suffered back pain at their computer. But when they looked at the figures for 16-24 year olds, that jumped to 80%.

Either these young peoples' problems will settle down in time - or the fact they've been using computers from a young age, together with other social trends such as obesity, mean that posture-related problems are going to significantly increase over time.

I know which my money's on...

Benefits of Laptop Computer Stands

The passing days are making it more and more obvious that skeletal health and ergonomic conditions of human beings is directly correlated with the way that we use our laptop computers. And each day, laptop computer stands are finding a stronger place in our daily lives compared to yesterday. Laptop computer stands are useful if you use a laptop on a regular basis at your home or office.

The human spinal system is delicate. If you keep stressing it consistently and continuously to make it do what it was not designed for doing, it is going to lose its health. That is exactly what happens when we keep using our laptop computers day in and day out. The laptops are not designed in a way that you shall find comfort typing in. They are designed for convenience. As a result, your health may seriously suffer if you do not use mobile computer stands.

The main benefits of using laptop computer stands are highlighted below.


Ergonomics: A mobile computer desk adjusts the height and you can use your laptop sitting on your chair if you have a stand in place. Thus, you get to sit in the ergonomic position that you are the most comfortable with.

Ease of multi-posture use: You can easily adjust the height and position of your laptop stand many times a day if you feel that changing postures while working is good for your health and comfort.

Portability: Mobile computer stands with wheel bases are portable. You can carry them all over your house and use them from almost anywhere at home that you want to.

Space efficiency: Folding these away is extremely easy. If you do not plan to use your stand for some days or hours, you can simply fold it and move it out of sight. In fact, if you have one with a nice décor then you may not feel like folding it away too much since a part of your nice house décor would appear to be missing.
Thus, using laptop computer stands can yield a high number of benefits that make using them an attractive option.

Factors to Consider in Choosing a Computer

Computers have improved a lot in terms of performance and multi-tasking. There has been an increased demand of these electronic devices lately because computers are now important machines used in everyday work.

Computers come in different models and vary in specifications and design. Some individuals who do not have technical knowledge on computers purchase the pre-assembled ones while people who understand the basics better choose the parts and assemble it on their own. Assembling your own computer is best because you have more options to mix and match the parts based on your needs and budget.

Deciding on what computer to buy can be a challenging task. This article will provide you information on what factors to consider so you can decide what kind of computer will best work for you.

If you do not have the technical know-how, it is advisable to purchase pre-assembled units. You can ask assistance from to see what kind of setup will work best in your work lifestyle and budget. Purchase the computer from an authorized dealer so that your unit will have a warranty.

Whether you are buying pre-assembled PC or want to assemble your own, it is important to know the components and its functions so you can have a basis of your decision.

The most important part of the computer is the CPU. It is considered the brain of the computer. It is responsible for the overall speed whenever it is processing any task.

There are two manufacturers who have dominated the market in producing processors. They are the AMD and Intel. Intel's most popular processors include the Pentium based and Celeron. Meanwhile, the AMD's flagship is the Athlon and Sempron based processors. AMD processors are generally cheaper than Intel's.

The motherboard is the device where all the parts and devices are attached. Some motherboard comes with onboard components which include video card, sound card, LAN card and modem. It is also important to consider what devices you are going to attach to the ports of the motherboard, and buy accordingly.

The RAM (random access memory) is the part responsible for the overall performance of the computer. The bigger the RAM, the faster the computer can process data. If you have enough budget, purchase the maximum RAM supported by your motherboard.

The video card is another important component. The quality of the image is due to the capacity of the video card. If you are into graphics designing and gaming, it is best to choose the highest memory of video card 3D capable. The high quality video card is also advisable to those who are fond of watching movies in their computer.

The hard drive is the storage device where all programs and games are installed and all other files are stored. If you love to collect a lot of videos and graphics, it is best to choose the highest capacity of storage. It is measured in terms of gigabytes.

The sound card is the part which processes audio signals going to the speaker. If you are going to connect your computer to a 5.1 speaker, then you should choose the best sound card capable of producing a surround sound. This is important when playing a lot of music, watching videos or playing video games often.

The power supply is responsible in powering your computer. It should be able to supply the necessary power for all the components of the computer. Never use cheap types because it is prone to seriously damage any of the components of the computer if it malfunctions.

Also consider the bundled software which includes the operating system, productivity software, anti virus and many other useful applications. If you are going to use other software you need for your work, make sure that the computer is capable of running it without any problem. Consider the compatibility of your software versus the specifications of your computer unit.

Also, list down other devices you may want to include to complete your computer setup.

3 Quick Fixes For Bad Posture

My mother used to always say, "Stop slouching!" when I was young. Most people can relate to that, but if you're like me, most people didn't listen to their mothers and carried the bad habit of poor posture into adulthood.

Most of us long ago accepted our posture and simply live with it, not realizing that good posture is a choice, and there are some simple ways to address, and ultimately improve your posture.

1) Exercises

There are many exercises that have been developed to help increase upper back strength, thus improving posture. One of the most effective is also the easiest:

Lie face down on a mat or soft surface. Turn your head to one side and place your arms out, with elbows bent 90 degrees and palms down, approximately level with the top of your head. Raise your head upper back from the floor as far as is comfortable, while keeping your feet and legs on the floor. While keeping your arms bent 90 degrees, raise your elbows using the muscles between your shoulder blades, and hold for up to 10 seconds. Repeat this 5-10 times, more as you gain strength.

By strengthening the upper back, you'll stand straighter, with more confident posture.

2) Ergonomics at Your Desk

Since most of us spend as many as 10 hours a day at our desk, working at a computer, having correct workstation ergonomics and body posture can literally train you for sustained, proper posture. For a detailed description of how best to configure your desk, chair and body position, see the Workplace Ergonomics Quick Reference guide, published by the Computer/Electronic Accommodations Program, under the Office of the Assistant Secretary for Health Affairs, US Department of Defense. Here is the address: http://www.tricare.mil/CAP/Ergo_Guide/setup.htm

There is also a detailed PDF file on the site, which you can download for future reference.

Since good posture is truly a habit, you can use your time spent at your computer to master your posture.

3) Posture Corrective Braces

Probably the fastest way to improve one's posture is by the use of a posture corrective brace. There are many available on the market, of all shapes and sizes. One drawback with most posture braces is that they tend to do the work for the wearer, pulling the shoulders back and maintaining correct posture by the strength of the apparatus, rather than the strength of the user's back muscles. This is a case where a quick fix can cause negative long-term consequences, as the user's back can actually weaken over time, which in turn causes posture to get worse and worse.

There is one posture corrective brace that was developed specifically to utilize the wearer's own back muscles to maintain correct posture. The PostureNOW posture brace, when worn correctly, provides very little force against the shoulders, so the wearer uses his/her upper back muscles to maintain proper posture. Over time, the muscles get stronger, muscle memory is developed and good posture becomes a habit, rather than becoming dependent on a posture brace to stand up straight.

Maximize Your Results

Any one of the above methods will help to improve one's posture. For those who are serious about improving posture, the combination of exercises, correct workplace ergonomics, and an effective posture correction brace such as PostureNOW, will provide significant benefits and long-term improvement in posture. Start now, because it's never to late to improve your posture.

Neck Pain After Extended Computer Use

You sit down at your computer, ready to put in a full day's work and make some serious headway on your projects. You know you'll easily be spending 8 to 10 hours sitting in front of the computer.

You've set up your computer workstation as effectively as you can figure. Your keyboard is appropriately placed in front of you and your monitor is directly in front of you at eye level. So why will your neck start to hurt? Why will your effectiveness be destroyed by the nagging, aggravating neck pain that seems to show up more and more frequently?

If you are regularly spending a lot of time in front of a computer, you have to realize that your body is going to begin to change and adapt to take on this frequent activity. Your front neck muscles are slowly growing shorter and tighter, while the muscles in the back of your neck are growing longer and weaker.

The back muscles are also growing full of spasm and knots while they are forced to hold up your ten pound head for hours at a time. You would think they would grow stronger from having to hold your head up all the time, but it just never seems to work that way. As they get longer, they are growing weaker, and the job of holding up your head becomes increasingly difficult.

The best options are to do exercises and activities that will counteract the extended computer usage. The rule of thumb is to spend time stretching the front of your neck and strengthening the muscles in the back. This same rule applies to anyone looking to improve posture.

To stretch the front of the neck, turn your head slightly to one side, about forty-five degrees. If you turn your head to the right, you are stretching the left and vice versa. Place your right hand on left side of your chest and pull down gently as you tilt your head back. Stop immediately if you feel sharp pain or any dizziness.

To strengthen the back of the neck, the easiest route would be with a neck exercise machine. Some health clubs have them, but they are more of a specialized device. You can also fold up a towel and place it against a wall. Put the back of your head against the towel and push into it. Hold for a few seconds and release. This is an isometric contraction.

If you are unable to complete some of these movements, or you find that you can't painlessly move your head backwards, it may be time to visit a chiropractor. The chiropractor will perform a spinal adjustment and restore the normal movement of your spine.

Your neck shouldn't hurt just because your sitting in front of your computer. You've got to work and pain can be a nuisance, but it doesn't have to be there with a little effort.

Common Computer Workstation Mistakes and Solutions For Pain Relief - Part 1

If you are experiencing pain in your wrists, fingers, hands, neck, shoulder or back and work at a computer for more than four hours per day there it is time to take a close look at how your computer workstation is designed.

Following are a few of the challenges I have seen in thousands of workstation designs. Does this sound like you?

Chair Armrests Too High Or Low:

In most instances the armrests are adjusted too high. Most keyboards are placed on surfaces too high for them and the computer user will adjust the armrest to the height of the work surface thinking this is supporting them properly.

They are inadvertently raising their shoulders to a tensed position. If the shoulder muscles are tensed for any length of time with repetitive motion in the hands or arms, varying levels of pain or discomfort may develop depending on the length of time in this tensed position.

Solution: Adjust the armrests up or down so that the shoulders muscles are in a relaxed position while resting on the armrests. If your shoulders are shrugged at all then the armrests are too high. If you are leaning into either armrest this could be an indication that the armrests are too low. The best way to do this is to drop your arms down by your side and just let your shoulders relax. It is important that you get a "feel" for this. In this fast paced and competitive world computer users are so focused on their work that they are not aware of the physical comfort changes that are occurring in their bodies on a daily basis.

Improper Sitting Posture:

If you are slouching in your chair you might be reducing your ability to take deep breathes due to collapsing your diaphragm. This can cause fatigue and discomfort because oxygen and nutrients cannot travel efficiently to your lower extremities and your brain.

Solution: Sit all the way back in your chair with the lower part of your back firmly touching the backrest. This will enable you to sit in a neutral posture with ease. Be sure you know how to adjust your chair. The chair is the foundation of the computer work area and if you have a great chair that is not adjusted properly then it will not do you any good. You want you feet to be flat on the floor or on a footrest.

Monitor Too High Or Low:

If the monitor is too low it requires bending the neck forward or down to view the screen. In high position the neck will bend backwards to read the screen.

Solution: Try this exercise. Relax your head and neck. If you do this correctly your head will be in a slight forward tilt. Now relax your eyes by letting your eyes "fall" to their lowest position in your eyes. Notice the lowest line on the screen you can read without raising your eyes or head. Position the monitor height so that the information you are reading is centered in this area.

For 19-21" monitors the top of the viewable screen will be approximately 2" below the line of sight. The line of sight is defined as the imaginary straight line from your eyes to the screen. Let your eyes and body determine what is comfortable.

Monitor and Keyboard Not Centered Together:

The computer user often will have the monitor placed to the side and will twist their neck left or right to view the screen. This added tension in the neck can create varying levels of discomfort.

Solution: Place the keyboard directly in front of the monitor so that you can look at the monitor without turning your neck sideways at all. If you use the mouse frequently and do not use the number pad on your keyboard you may consider an ergonomic keyboard with a 15" footprint. This will balance the keyboard AND mouse with the monitor.

Be on the lookout for Part 2 in the next few days...

Computer VDU Eye Strain - Top Tips to Take Care of Your Eyes - Eye Care Advice From Opticians

Today an increasing number of the public work with a Visual Display Unit or VDU. Laptops, Personal computers and workstation screens in the office environment. The numbers of hours we spend sitting in front of computer is increasing all the time, be it a project for work, reading emails or data entry.

We live in modern times, where the computer viewing has become a necessity on our lives. In today's work environment is can become difficult to get the rest breaks your eyes need on a computer.

Most VDU users know the guidelines for workstation set up in terms of seating height and distance to screen. However may not have the knowledge about the affects of poor blinking frequency and not taking eye rest breaks.

Eye care points below can help stop and reduce VDU eye strain. A sight test conducted periodically is also advised. Once 40-50 minutes of computer screen focusing has passed a break in viewing the VDU is ideal.

Nowadays taking a 5 minute break can be a challenge. High expectations from employers and time frames for work completion to be met.

Rotational eye movement in a clockwise and anticlockwise motion with the eyes closed, with controlled inhale and exhale deep breathing. Open your eyes after the deep breaths, and repeat as necessary. Can be completed easily a few times over the break period.

The eye surface must be kept wet and hydrated. Blinking helps introduce tear fluid across the corneal surface to achieve this. VDU users tend not to blink as often when concentrating on a visual task.

Dehydration can be a factor in an air-con or heated environment. Drink plenty of fluids throughout the day. Not able to take a 5 minute break. Then at least look away from the screen. Take visual focus breaks every 10 minutes.

Whilst sat in the seated position still at your workstation turn your head away from your screen. Look at distant objects either at the far end of the office or outside of a window.

Eat healthy fresh citrus fruits, green leafy vegetables like spinach, broccoli. The anti-oxidant properties help maintain the eye health and function.

Most VDU users are not aware of employer obligations to provide eye examination checks. Visit below for more information

Fixing Bugs and Other Malicious Programs in Your Computer

Frequent online visits to certain websites may seem harmless. However, after you sign out and the next time you turn on your computer, you may be surprised to notice how its performance has started to slow down. The first thing that probably comes into your mind is that your system probably contacted an internet virus or a malicious software program from the websites you last visited.

Well, chances are, you are right. But perhaps you are wondering how this has happened when you cannot remember allowing any software installation process. The thing is that malicious programs get into your computer without you knowing it. As simple as clicking a given link can get you hacked by strangers. This poses as a big threat to your security and not only that, these files necessarily slow down your computer as they consume a big space in your hard disk.

Remember that once they are in your computer, these malicious software programs do not need your permission to run. As your computer ends up accommodating these programs that run simultaneously, they necessarily consume big memory space, hence, slowing you system's response to your command. Reinstallation can cause data loss and is not advisable. An alternative comes with using a Registry Cleaner.

A Registry Cleaner can fix all the bugs that have infested your computer by performing a thorough scan and eliminating them. The difference between a Registry Cleaner and an antivirus software programs in this case is that the former only deletes Trojans, viruses and other security threats. On the other hand, the Registry Cleaner goes further by deleting even the obsolete files you have in your system as well as the residue of uninstalled software programs or improperly installed programs. The Registry Cleaner also performs clean up of historical data to ensure that any account information you have sent online will not be accessible to malicious individuals.

The Ergonomics of a Chair

With hundreds of millions of people sitting at a desk as their job, it's no wonder that people are taking more and more notice of ergonomics. Ergonomics is the study of designing jobs, equipment and workplaces to suit the workers. For example, desk heights are adjusted for different height people because of what ergonomics has revealed. Poor ergonomics leads to people being uncomfortable, and will eventually result in injuries that can even be permanent. For those of you who have fallen asleep on the couch, you would know that a couch isn't designed for sleeping on and you most often wake up with a sore back or neck!

Chairs have ergonomics too. A good chair is adjustable, or it suits you in every way when you originally purchased it. The height of the chair, length of the back, angle of the back, shape of the back and even the material used all play an important role in your chair. Office chairs are becoming increasingly more ergonomic, but it's not surprising to see people sitting in poor quality chairs for more than 40 hours a week. When you really put it into perspective, even 300 dollars is well spent on a chair if you are going to sit in it for thousands of hours over the period of your lifetime.

Having the chair the right height is a good start. Ensure that your feet can touch the ground without any issues, but that you don't have to stretch your legs to make it comfortable. Ensure the chair height matches the desk height, and that your monitor is the right height to match the chair. All of these things come together and influence each other; get them right or you will suffer injuries later on.

Why Use Multiple Threads?

In many situations, having more than one thread running in a program is beneficial. Here's a more in-depth look at why this can be good.

Better Interaction with the User

If only one thread was available, a program would be able to do only one thing at a time. In the word processor example, how nice it was to be able to open a second document while the first document was being formatted and queued to the printer. In some older word processors, when the user printed a document, he or she had to wait while the document was prepared for printing and sent to the printer. More modern word processors exploit multiple threads to do these two things at the same time. In a one-processor system, this is actually simulated by the operating system rapidly switching back and forth between two tasks, allowing for better user interaction.

From the perspective of a microprocessor, even the fastest typist takes a tremendous amount of time between keystrokes. In these large gaps of time, the processor can be utilized for other tasks. If one thread is always waiting to give a quick response to a user's actions, such as clicking the mouse or pressing a key, while other threads are off doing other work, the user will perceive better response from the system.

Simulation of Simultaneous Activities

Threads in Java appear to run concurrently, even when only one physical processor exists. The processor runs each thread for a short time and switches among the threads to simulate simultaneous execution. This makes it seem as if each thread has its own processor, creating a virtual multiple processor system. By exploiting this feature, you can make it appear as if multiple tasks are occurring simultaneously when, in fact, each is running for only a brief time before the context is switched to the next thread.

Exploitation of Multiple Processors

In some machines, several real microprocessors are present. If the underlying operating system and the implementation of the JavaVM exploit the use of more than one processor, multithreaded Java programs can achieve true simultaneous thread execution. A Java program would not have to be modified because it already uses threads as if they were running on different processors simultaneously. It would just be able to run even faster.

Do Other Things While Waiting for Slow I/O Operations

Input and Output (I/O) operations to and from a hard disk or especially across a network are relatively slow when compared to the speed of code execution in the processor. As a result, read/write operations may block for quite a while, waiting to complete.

In the java.io package, the class InputStream has a method, read(), that blocks until a byte is read from the stream or until an IOException is thrown. The thread that executes this method cannot do anything else while awaiting the arrival of another byte on the stream. If multiple threads have been created, the other threads can perform other activities while the one thread is blocked, waiting for input.

By dividing the work between two threads, the GUI event-handling thread is free to handle other user-generated events. In particular, you might want another button, labeled Cancel Request, that would signal the worker thread to cancel the interaction with the server. If you had not used a worker thread to perform the interaction with the server, but simply had the GUI event thread do the work, the interruption activity triggered by the Cancel Request button would not be possible.

Simplify Object Modeling

Object-oriented analysis of a system before it is built can lead to a design requiring some of the objects to have a thread running within them. This kind of object can be thought of as active, as opposed to passive. A passive object changes its internal state only when one of its methods is invoked. An active object may change its internal state autonomously.

As an example, consider building a digital clock graphical component that displays the current system time in hours and minutes. Every 60 seconds, the minutes (and possibly the hours) displayed on this component will have to change. The simplest design is to have a thread running inside the clock component and dedicated to updating the digits when necessary. Otherwise, an external thread would have to continually check whether it is time to update a digit, in addition to performing its other duties. What if that external thread had to read data from an InputStream, and it was blocked, waiting for a byte for longer than a minute? Here, exploiting the benefits of multithreaded programming simplifies the solution.

The Different Features of the Corner Furniture Computer Desk

Office furnishings are the key elements of interior decoration in the setup of an office. Such setup comprises of furniture like corner computer table, laptop stands and filling cabinets. Office fixtures must match organizational goals of the company. For example, if the business deals with advertising, then the office appearance must be casual, laid back and must be in accordance with modern fashion or if the office is a law firm it needs to have serious, professional and comfortable office furniture. As being said, the first is lasting and important. The clients or visitors take a keen observation of office fixtures. The following is a concise guide on some office furniture:

Corner computer desks vary from different usual desks since they occupy lesser space and provide sufficient room for the user to the job freely. Corner computer tables were proven to be modern since they give additional space in the workplace and the structure suits well in a room where the space is constrained or little. The equipment not only gives more room space for your job but it also suit perfectly in the corner and the equipment provides a professional appearance to the decoration.

Laptop stands are new office fixture, since they are replacing big bulky desktops which need a large computer table. These tables are replaced by slender, solid laptop stand that needs very small space in the room since laptop stand occupies five times lesser space compared to computer table. By using laptop stand the effectiveness of laptop is enhanced since majority of laptop stands avoid the equipment to get heated therefore adding more existence to the scheme. The slender and smooth structure of the stand makes it movable since it needs little space, so you may bring it to the park, airport, or in the restaurant. Wherever you go, you bring your office with you.

Filing cabinets are pieces of office equipments which are used in storing vital information and filing records of the company. These cabinets are the most regular office fixture since they are found in all offices, they are essential for running the business in systemic manner. If the office has no filing cabinet, the files would scatter all over the place. There are 3 main types of filing cabinet such as shelf filing, vertical filing and lateral filing cabinets.

New Computer - Old Email, or How to Back up and Transfer Your Email

If you have a brand new computer, or are thinking about buying one in the near future, one of the things that you will need to consider is how to transfer your emails from the old system to the new system.

At least once a week in my job as a help desk analyst, I am helping a customer set up Outlook Express or Outlook (there are other email clients that are used, but these two are the most popular) on their new computer. Once we are finished with the setup and they open it up to the Inbox the question is asked "where are my old emails?" The simple answer; "on your old computer". Then of course the follow up question is; "how do I get them to the new computer?"

Easy or Hard

The easiest way to do this is to back them up to an external hard drive or a compact disc before you make the switch to the new computer and then copy them over to the new computer in the exact same directory. The harder way is in the case of a crashed computer or the inability to access the files normally. I cover a bit of that in another article called 'Got Backups?' which you can find at my website.

Outlook Express

With Outlook Express your emails/email folders are stored on your hard drive in a directory that is buried way down deep in the Operating System. Instead of me giving you the full path to get there, it's easiest if you have Outlook Express open, click on Tools then Options.

Copy/Paste

Once you are here, click on the Maintenance tab and then click on the Store Folder button. This will pop another window with the location of your emails. Using your mouse, highlight the path and then right click and copy it.

You will then click on the Start button, then click Run, and then right click in the Open box and Paste the path. Click Ok.

This will open another window with your email files. Unless you have added other folders to your Outlook Express, the default folders will be here with a .dbx extension (Folders, Inbox, Sent Items, Deleted Items, and Drafts).

Backup

If you are going to write these files to a CD, you can burn them at this time by using your favorite burning software (providing that you have a CD burner installed in your computer).

To copy them to an external hard drive, you must now connect that device to your computer, create a folder on that drive (I usually call it Email Backups), copy the files from the old computer then paste the files into the Email Backups folder.

Import

Once you have the files copied to the CD or external drive, then you will go to the new installation of Outlook Express and import the messages. It would be nice if you could just copy them to the new OE and be done, but Microsoft doesn't like you to do it that way.

Open up OE and then click on File, Import, Messages. This will open a new window called Outlook Express Import. Choose Microsoft Outlook Express 6 then click Next. Click in the circle that says 'Import mail from an OE6 store directory'. Click OK. Then click 'Browse' and navigate to and select the directory you have saved them to. Click OK. The next window will give you a list of all of the email folders you have previously saved. Keep 'All folders' selected and click Next.

This will begin the process of importing all of your 'old' emails into your 'new' Outlook Express. Once it has finished you will have all of your old emails back! Cool, huh?

Outlook

The procedure to save and then import your emails in Outlook is similar, but different.

To start with, Outlook uses a file extension called pst, or Personal Folder File. Don't ask me why it's called that. Call Bill Gates and ask him.

Export

You will start on the old computer and with Outlook open, click on File, then 'Import and Export'. This opens the Import and Export Wizard. Choose 'Export to a file' then click Next. Choose 'Personal Folder File' here and then click Next. In the Export Personal Folders dialogue box you have your choice of what you want to do. The easiest is to keep the default choice of just the inbox, but if you want your sent items and all the other folders, choose the top item (Personal Folders) and then choose the 'Include subfolders' option and then click Next.

The next window will have a default location listed
(usually C:Documents and Settings'your computer name'Local SettingsApplication DataMicrosoftOutlookbackup.pst). I would suggest following the same procedure as for OE (see above). Then click 'Finish' and let it do it's thing.
Once you have your pst files backed up, move to the new computer and the import process will again be similar to OE.

Connect your external hard drive to your computer or insert the CD into the drive.

Import

Open Outlook, click on File, then Import and Export. In the Import and Export Wizard, this time choose 'Import from another program or file' then click Next. In the 'Import a File' window, scroll down and select Personal Folder File (.pst) and then click Next.

In the 'Import Personal Folders' window, click the Browse button and navigate out to the location of your backed up pst file, choose it and then click Next. Click 'Finish' and it will import all of your messages.

Computer Assembly - What You Need to Know First

So you want to build your own computer? That's great! Too make things easier its best to follow these simple guidelines.

1. A workstation with plenty of room and good lighting. Whatever you decide to use make sure you line it with newspaper if you want to avoid scratches. PC cases and their components have sharp metal points and can easily scratch a table. Make sure you have adequate lighting. A desk lamp would be great as you can adjust it towards the part of the case you are working in.

2. Don't try and build your computer before you have all the parts. It's very easy to forget essential parts of the system. You may wonder why your PC is not working only to find you have skipped a simple cable. So make sure you have all the components and manuals.

3. Take care when handling the components for your PC. All components come in anti-static packaging. Keep them in that packaging when you're not using them. It is very easy to blow some components with static electricity. Especially memory modules.

4. Be gentle with the components. If you can't get it to fit, take it out and check the manual again to make sure you are putting it in the right place. All components can only go in one way.

5. Take the time to read the manuals provided for each component before trying to install. This can save you a lot of time in the long run.

6. Don't throw away your packaging and receipts. In rare occasions you may have a faulty item so you will need these to return it for a replacement. The same applies when you upgrade your components. It will make it much easier to sell again.

7. A lot of components come with extra screws and cables that you will not need. Store them in a "spare parts" container. You will be surprised at how often you will need these in the future.

8. A magnetic screwdriver is a great tool to have. You wont believe how many times you'll drop a screw in a hard to reach place.

9. Check all the connections for all cables after assembly. Its very easy to work a cable loose when working on a different component.

A lot of people are worried about breaking things during the first PC assembly. Just take care and follow these guidelines. Most importantly, enjoy the process!

You can just look at the models available at the nearest furniture store and choose from them. However if you wish to look for more choices online shopping is ideal for you. Online shopping offers you discount rates on these types of desks.

Cost effectiveness of online shopping however depends on the website you choose to buy from. You need to know whether the one you are ordering has any delivery charges or not. Moreover, these desks are usually shipped in parts and need to be assembled when the product reaches you.

IP PBX Phone System = Free Long Distance?

An IP-PBX phone system can be hardware appliance, or virtually, as a software system running on a workstation computer. Due to the fact that a major part of IP PBX phone system functionality is software based, it is relatively inexpensive and easy to add features that can exist in only enterprise level business phone systems.

Getting an IP PBX for your office, doesn't necessarily mean that you have free long distance. This is a typical misconception I have seen with any new prospect that I meet.

The truth is that an IP PBX, by virtue of the technology that has created it, has the ability to instantly connect to various VOIP service providers who are able to give you dial tone or phone line via your existing broadband internet connection. No expensive upgrades required. Just connect your IP PBX phone system to the internet and setup your internet phone line or VOIP Line.

And depending on what deals your VOIP phone telephone line company has to offer, you can get free unlimited calling to some countries or absolutely free calling to any place in the world!

Residential VOIP phone service may be cheap when you calculate the cost of all the features bundled into one low price. But when it comes to business VOIP, I beg to differ.

Consider this, a good business VOIP service will cost you between $22.95 - $32.95 per month. If you need more than 3 channels for simultaneous outgoing calls (called multi-line or hunt group in traditional telephony  terms) you may as well opt for a dedicated broadband access which will cost you around $59.95 a month ...remember this is a business account and you will pay a premium for the better grade of service and support.

Taking the lowest figures you will end up spending $128.8 for a 3 channel VOIP trunk. And this works out to minimum $43 per line. Compare this with your friendly neighbourhood landline provider with the features that both offer and then make an informed decision.

Don't buy VOIP just because of the hype. Remember, when you buy VOIP, you are also relying on the broadband service provider. Whereas, in case of landlines, there is a direct copper wire circuit connecting you directly and exclusively to the telephone company's switching network.

Maintain Your Own Point Of Sale System

Computer Hardware has become Plug and Play

When you purchased your computerized point of sale system one of the reasons was probably because it was an open architecture system. That meant that it was standard hardware with special software designed for your business. While the software may be specialized, the hardware was probably standard and easier to find replacements than you imagine.

The term "plug and play" may refer to some sort of video or audio component but it also describes how easy computer hardware is to replace when broken or worn out. You simply look at the model number of the device that is broken or defective and purchase a similar one to replace it. No software is needed in most cases, with the software drivers already being loaded in the operating system of your computer. Connect the cables to the replacement hardware exactly like they were on the broken hardware and you are back in business.

Pay Yourself Instead of the Technician

Let's say you need to replace a printer on your system. You have choices that you may not realize.

You could call the company that installed your system. They will probably offer to repair the printer first. After all, they are in business to maintain your system. If you select this option there is probably a service fee in addition to you buying the parts for the repair. The dealer will make money on the fee, and you will pay full list price for the parts. In the end you will have a repaired printer with possibly a 30-day warranty. Look for a bill of $200 or more.

You could call the company that installed your system and they may offer to wave the repair fee is you purchase a replacement printer from them. This printer is going to be around $495 for a standard thermal printer. Hopefully, you are not hit with an installation charge. If you are look for an additional bill for $95 - $125 for a total bill to replace the printer of $580 - $615. Ouch! If the dealer has the printer in stock you probably will have your new printer the next business day.

Or you could pay yourself. Replacement printers as the one I used in the example above can be found on the Internet for $295 every day. Shipping will range from $0 to $25 depending on the site. If you just have to have it overnight then you will have to pay the charges. Overnight charges could run around $50 for this printer. So, worst case you pay $349 to have a NEW printer delivered overnight. You unplug the broken printer and plug in the new one and you are back in business. You received the same printer the dealer was going to sell you and you plugged it in yourself. You just saved yourself a minimum of $149 and now have the same printer with a full manufacturer warranty. In most cases, this is a 3-year warranty.

Think "Easy" Because it is

Most service calls for point of sale systems are now handled via the phone. Onsite support is fast becoming a thing of the past. More and more companies are going to a "hot swap" mentality and shipping replacement hardware and expecting you to install it. Their sales pitch is that it is easy and will save you a service call.

My point is simple. If they are going to send you the replacement hardware and expect you to plug it in then it must be fairly easy to do. I am suggesting that you now get smart about where you get the replacement hardware and don't pay more than you have to.

Don't pay an electrician to change a light bulb and don't pay a technician to replace a printer.

2 Proper Computer Postures That Help

Have you ever suffered from a terrible headache or neck pain after prolonged hours of work using your computer? If you do, then you may be one of the people who are suffering from various types of pains due to improper posture when using a computer. Studies have shown that improper posture greatly affects the wellbeing of your body by altering the blood flow and straining the eyes. This is why efforts should be done to achieve that proper computer posture that help you feeling better and relaxed while you work.

Improper posture causes headache, back pains, neck pains, and the general feeling of a fatigued body. If left unchecked, this could lead to some serious and permanent ailments that could have otherwise been corrected earlier. In order to achieve that proper computer posture, you must have a workstation that fits your body physique. This is because if there is a mismatch between the size and position of the workstation with your total body structure, the tendency is for you to compensate by unnaturally positioning your body in such a way that may later on cause some ailments.

To have a proper computer posture, you must enlist the help of some of the basic office furniture that you can find. First off, change your chair. A great number of people actually discovered that a good chair does not necessarily mean the one that is being used by the supervisor but rather, is one that easily adapts to their bodies. You may want to select a chair that is both stable, fits your body comfortably, and can easily be adjusted for proper height and tilt.

Try to test a couple of chairs that you can find in your office and select the one which you feel most comfortable with, just make sure it is not the one used by the boss, otherwise you might suffer more than just an eyesore, a neck or back pain. Try it out in front of your workstation for a couple of hours. If you feel the pain is ebbing, then it could be the best chair for you.

Another factor that you have to consider in order to achieve a proper computer posture is the work surface. A lot of people have found it most comfortable when the desk height is just about the level of their elbows when they sit down. This would place the computer monitor at a comfortable eye level without you having to position your head in such a way so you could see what is being typed.

There are still a lot of proper computer postures that you can follow. The two proper computer postures mentioned are just examples of how you should position your workstation to adapt to your body. Once done, you would definitely feel truly comfortable.

Home Based Business - 12 Ergonomic Tips For Your Computer Workstation

When working from your home office you may have a tendency not to take as many breaks as if you were in a traditional office. You may find yourself working for hours before getting up from your chair, as the interruptions are normally fewer to distract you. Because of this it is critical that you take care of yourself - and arm yourself with the basic ergonomics to prevent or at least minimize any physical strain due to computer work.

Here are 12 tips for setting up an ergonomic computer workstation:

1. Use a good chair with a dynamic chair back and seat pan. Sit back and use it instead of leaning forward

2. Position the top of monitor casing 2-3" (5-8 cm) above eye level

3. Use a no glare screen, and an optical glass anti-glare filter where needed

4. Sit at arms length from the monitor

5. Place your feet on floor or stable footrest

6. Use a document holder, preferably in-line with the computer screen

7. Keep wrists flat and straight in relation to forearms to use keyboard/mouse/input device

8. Your arms and elbows should be relaxed and close to body

9. Center your monitor and keyboard in front of you so you are not turning to use them

10. Use a negative tilt keyboard tray with an upper mouse platform or downward tiltable platform adjacent to the keyboard for best wrist angle

11. Use a stable work surface and stable (no bounce) keyboard tray

12. Take frequent short breaks (microbreaks)

Ideal typing posture: Negative slope keyboard support

In the ideal typing posture both static and dynamic muscle loads are minimized. This posture is achieved when the keyboard is below seated elbow height and the keyboard base is gently sloped away from the user so that the key tops are accessible to the hands in a neutral posture. In this position the arms, shoulders, neck and back can relax, especially during brief rest pauses. Also, in this slightly reclined sitting position the low back rests against the lumbar support of the chair, the elbow angle is opened to promote circulation to the lower arm and hand, the abdominal angle, and the popliteal angle (behind the knees) are opened to promote blood circulation. The feet rest firmly upon the floor.

Problem postures:

Desk top keyboard - Typing at a keyboard on a desk is a common work posture for many computer users. In this position it is difficult to maintain the wrist is in a neutral posture, because the forearms sag as they tire and this puts the wrists into greater wrist extension. Also, most users have to work with their elbows flexed, which can compress the median and ulnar nerves at the elbow and restrict blood flow to the hands. Working with the forearms sloping up increase muscle loads in the upper arms, shoulders, and neck. Working in this position for more than 3-4 hours invariably leads to muscle fatigue.

Conventional keyboard tray - Typing at a keyboard on a conventional articulating keyboard tray can increase postural problems for users. Working with the keyboard more steeply angled on the tray is a common work posture for many computer users. In this position it is also difficult to maintain the wrist is in a neutral posture, because the forearms sag as they tire and this puts the wrists into greater wrist extension. Studies have failed to show that conventional keyboard trays substantially improve wrist posture.

Of course there are other ergonomic factors as well such as proper lighting, ventilation, mouse use, furniture heights and styles, plus phone equipment to name a few. Be sure to research what will be best for your specific situation and budget. Take care of your body now and it will take care of you in the future.
