how to sit infront of comuter

s salam o alaikum Friends,

We spend a large portion of our lives sitting, especially during the computer age, so it’s important to learn to sit tall. One of the most common mistakes we make is that when we move into a sitting position, we tend to aim for the center of the chair. The proper method is to sit deep in your chair.

Posture ranks at the top of the list when talking about good health. It is as important as eating right, exercising, getting a good night’s sleep and avoiding harmful substances. Unnatural alignment of the body can cause head, shoulder, neck and back pain, and compromise neurological, digestive, respiratory and cardiovascular functioning.

Unquestionably, students and adults alike spend more time at computers today than 20 years ago. So here are nine tips designed to help people’s posture when they’re at the computer at home, school or work:


1. Support your back.

Does the chair you are sitting on have enough lumbar support? The backrest should fit into the natural curve of your lower back, filling in the space between your back and the back of the chair. This helps avoid excess pressure on the spine and makes it easier to maintain good sitting posture.

Adequate lumbar support also helps prevent muscle fatigue, which causes many people to lean their heads and upper backs too far forward or to slouch downward. With good lower back support, spinal muscles are relaxed and the spine is able to maintain its neutral position.

2. Comfortable leg postures.

To promote comfortable leg postures, consider clearing away items from your legs to allow comfortable leg positions and movement. Feet should be flat on the floor or you may use a footrest if your feet do not rest comfortably.

3. Minimize reaching.

Position work station components to minimize reaching and twisting. Keep frequently accessed objects as close as possible to body centre.

4. Comfortable shoulder and arm postures.

Place your keyboard and mouse or trackball at the same height; these should be at about elbow level. Your upper arms should fall relaxed at your sides.

Also when typing, center your keyboard in front of you with your mouse or trackball located close to it.

5. Wrist and finger postures.

Keep your wrists straight while typing and while using a mouse or trackball. Avoid bending your wrists up, down, or to the sides. Use the keyboard legs if they help you maintain a comfortable and straight wrist position. Type with your hands and wrists floating above the keyboard, so that you can use your whole arm to reach for distant keys instead of stretching your fingers.

Make sure you keep your fingers relaxed while typing and using a mouse. Use a soft touch on the keyboard instead of pounding keys with unnecessary force.

Also grasp the mouse gently and avoid holding a pen or anything else in your hands while you type or use the mouse. You should relax your fingers and hands between bursts of typing or mousing using a flat, straight wrist posture.

When moving your mouse, you may be more comfortable if you use your arm, not just your wrist. Choose a mouse that fits the size of your hand comfortably and is as flat as possible to minimize wrist strain.

6. Minimize neck bending and twisting.

Center your monitor in front of you. Consider placing your documents directly in front of you and the monitor slightly to the side, if you refer to your documents more frequently than your monitor.

Sit comfortably in the chair. Close both eyes and relax. Then, slowly reopen them. Where the gaze initially focuses should be when the eyes open is the place to put the center of the computer screen. The screen can be raised using books or a stand if needed.

7. Minimize eyestrain.

Place your monitor at a distance of about arm’s length when seated comfortably in front of the monitor. Also avoid glare. Place your monitor away from light sources that produce glare, or use window blinds to control light levels. Don’t forget to adjust your monitor brightness, contrast, and font size to levels that are comfortable for you.

Throughout the day, give your eyes a break by forcing them to focus on something other than on your screen. Try the following exercise: Hold a finger a few inches in front of your face; focus on the finger as you slowly move it away; focus on something far in the distance and then back to the finger; slowly bring the finger back toward your face. Next, shift your focus to something farther than eight feet away and hold your eyes there for a few seconds. Repeat this exercise three times, several times a day.

8. Take short breaks.

Taking breaks can help your body recover from any activity. The length and frequency of breaks that are right for you depend on the type of work you are doing. Stopping the activity and relaxing is one way to take a break, but there are other ways, also. For example, just changing tasks - perhaps from sitting while typing to standing while talking on the phone can help some muscles relax while others remain productive.

9. Periodically look up at the ceiling to give your posture muscles a break.

So, improve your sitting posture and remember, a healthy lifestyle can help you perform and enjoy your everyday activities, including the time spent at your computer. Learning more about working comfortably and productively, as well as your overall health, are important ways to help you enjoy your computing experience.

Greasemonkey and FB Purity
Although Facebook does not allow the ability to hide friends getting new friends messages, friends becoming fans of something, and some application messages they can still be hidden with browser add-ons. If you're running Mozilla Firefox, Chrome, Opera, or Safari we suggest installing the Facebook Purity add-on.
Update your privacy settings
Click Account in the top right corner of the Facebook window and then click Privacy settings to adjust who is capable of seeing what on your Facebook profile. We highly recommend going through all the privacy settings to verify your privacy is properly protected.
Anything that is not set to friends only or friends of friends can be seen by anyone searching on the Internet. Below is a few things we recommend for most users.
  1. Under Search in Privacy settings uncheck Public Search Results. This will prevent users from finding your account and profile picture in search results such as Google
  2. Under Application settings, make sure you're only allowing applications you want to have access to your information. Applications that you grant rights to can have access to your Facebook profile information.
  • If you're curious to see how a program or web page connect to the Facebook API can see your profile seeTip135.
Use the Facebook top bar for navigation
Facebook navigation
Knowing how to properly navigate is vital if you want to get the most out of Facebook. Below is a brief description of each of the available options in the top bar as shown above.
Home (facebook logo) - Clicking this logo will take you to your wall (News Feed) that shows all friends recent posts.
Friend requests - If any friend requests are waiting to be approved this icon will show a notification of how many friends are waiting for approval. This icon can also be clicked when you want to view any friend recommendations or search for friends on Facebook.
Messages - This section allows you to send and receive private messages between one or more people you're friends with.
Notifications - Any time a friend or Facebook application creates a new post you'll be notified in this section. Clicking this icon will show all recent notifications. If you wish to change what is capable of sending you notifications including any Facebook applications or games click the See All Notifications link at the bottom and check or uncheck what you want to be notified on.
Search - Finally, the search box in Facebook can be a powerful tool that can be used to quickly find any current friends or people on Facebook. In addition searching for terms such as a company name, product, sports team, music band, etc. will find fan pages and groups that can be joined.

Keep your e-mail and your cell phone clean by updating or eliminate Facebook notifications or keep more up-to-date by adding new notifications. Facebook notifications can be added and removed by clickingAccount link in the top right corner, then Account Settings, and then clicking the Notifications tab.
Top News and Most Recent
Facebook News and most Recent
By default Facebook will display your wall postings in the News format, which means it only displays posts it believes are most relevant to you. These results are based on your past interaction with your friends. If you want to see every post made by all your friends that are not hidden click the Most recent link in the upper right section of your news feed as shown in the above picture example.
If you want to adjust who shows up manually click the Edit Options in the bottom right corner of your news feed.
Facebook unhide friends
View High School work friends
If you've added your High School or previous Work locations to your profile, quickly see all classmates and co-workers on Facebook by clicking the link in your Info tab under your profile.
Quickly change profile picture
Your profile picture can be quickly changed to any other picture by visiting your profile, hovering the mouse over your current profile picture, and clicking the Change Picture link that appears in the top right corner of the picture.
Don't post private information on friend's walls on in comments
When you make a post on a friend's wall or in any of their comments realize that any of their friends are going to be able to see that post. If you wish for something to remain only between you and a friend send them a Facebook message instead.
Suggestions and random friend invites
As you get more friends on Facebook it will begin making friend, groups, and fan suggestions. These are suggestions made by Facebook and not your friends. Unless these are something you're interested in they can be ignored.
This same rule can be applied to people who may want to be your friend that you don't know. If you don't know someone don't accept his or her friend invite. Once someone becomes your friend they'll have access to any information your friends are capable of seeing.
Tag your Facebook friends in your photos
Always make sure to tag any of your Facebook friends that are in pictures you upload. However, never tag someone who is not in the picture. When someone is tagged in a photo that picture is automatically added to that persons profile and is a great way to share pictures with all friends.

View two windows side-by-side using Smart Window


Smart Window or Snap, allows the user to view two windows side-by-side in Windows 7 without having to manually re-sizing either window.  This is also useful if you don't want to use Alt-Tab between 2 windows. If you are running a different version of Windows such as Windows XP or Windows Vista and want a similar feature see Tip138. Below is an example of what this looks like in Windows 7.
Windows 7 Smart Window
  1. Click and Drag on the top title bar of the first window so your mouse pointer hits either the left or right side of your screen. Let go of the window when you see the outline of the window re-size to ½ of the screen.
  2. Then choose the other window you wish to view on the side of the first window. Click and Drag the 2nd window to the opposite side of the screen until the mouse pointer hits the side of the screen and resizes to the other ½ of the screen.
These steps can also be done using the Windows key and the right and left arrow keys by doing the below steps.
  1. While pressing the Windows button on your keyboard, press either the Right or Left arrow.  This will move the open window to either the left or right portion of the screen.
  2. Choose the other Window you wish to view to the side of the Window in step one.  When using the Windows key for this step, as described in step one above, use the opposite (right or left) arrow button that you used in step one.
There are three different ways to get out of this view, below are some of the different methods this can be done.
  1. Click and drag the window so the mouse pointer hits the top of the screen and let go.  This will put the window back to regular size.
  2. If you just want to view one of the minimized windows that was in side by side view, click and while holding the mouse button down shake the window you wish to view and it will minimize all other widows to the Taskbar.  To reopen windows that were minimized by this step, click and shake the window you are using again, and they will re-appear.
  3. Press the Windows key on your keyboard, and at the same time, press either the up arrow or the down arrow.  The up arrow will maximize the screen; the down arrow will put the screen to minimize.

Top 10 computer mouse tips everyone should know


Most computer users don't take full advantage of the computer Mouse. Below are computer mouse tips and secrets that help you get the full potential of your computer mouse and increase your overall productivity while on the computer.
Shift key and mouse click
Many text editors and programs allow you to highlight all or portions of text using the Shift key and the mouse. For example, place the cursor at the beginning of a paragraph, hold down the Shift key and click at the end of the paragraph to highlight the full paragraph.
Take full advantage of the scroll wheel
Today, everyone is fully aware of a mouse wheels ability to scroll up and down on a page. However, this wheel can also do so much more, as shown below.
  • The mouse wheel is not just a wheel, it can also be used as a button. Pressing down on the wheel will act like a third mouse button. This can be used to open a web page in a tab by clicking the wheel on any link and can also be used to close a tab by clicking the wheel on any open tab.
  • Quickly Zoom in and Out on a web page, word document, excel spreadsheet, etc. by holding down the Ctrl key and scrolling up to zoom in and down to zoom out.
  • Move forward and backwards while browsing the Internet by holding down the Shift key and scrolling up and down. Scrolling down goes back and scrolling up goes forward.
Select with double and triple click
Any word can be easily selected by double-clicking the word. If you want to highlight the whole paragraph, click the mouse button three times on any text in the paragraph.
Use the right-click
Take full advantage of the right-click any time you highlight text or wish to view the properties of an object. For example, if you highlight a file or text, you can right-click that highlighted item copy it and then right-click anywhere else to paste it.
Tip If you right-click on any file or text and drag it while continuing to hold the right button, when you let go you will be given the option to move or copy that file or text. This saves you the extra step of having to right-click where you want to paste the item.
Tip While in a browser pressing and holding Ctrl while clicking on any link will open that link in a new tab.
Ctrl key and mouse click or highlight
While holding down the Ctrl key you can left-click to select multiple objects or highlight multiple sections of text. For example, in Microsoft Windows you could hold down the Ctrl key and click to select multiple files at once. If you wanted to highlight different parts of a paragraph or web page, you could also hold down the Ctrl key and select each section you wanted to copy.
Tip Mozilla Firefox users can also hold down the Ctrl key and individually click on each cell in a table they wish to copy or drag their mouse down a row to select just that row or text without selecting any of the other text in that table.
Use the mouse side buttons
Many new computer mice have buttons on the side of the mouse. These buttons can be programmed to do anything, however, by default the left-thumb button can be used to go back on a web page. This makes browsing the Internet more enjoyable since you do not need to move the mouse cursor to the browser back arrow button in order to go back a page.
Use the Windows Snap To feature
Take full advantage of the Windows mouse Snap To feature, which will automatically move your mouse to buttons that appear in a dialog box. For example, if you delete a file or close a window you may get a prompt asking you if you are sure you want to perform the task. With the Snap To feature enabled, the mouse cursor automatically moves to the Ok button, so all you will have to do is click the mouse button if you agree. This saves you the time of having to move the mouse cursor over to the Ok button and then click Ok. To enable this feature open the Mouse properties under the Windows Control Panel and check the Snap To check box under the Pointer Options tab.
Tip While changing this feature we also suggest looking at other available options in the Mouse settings. For example, increasing the Motion speed can also help increase your productivity while using the mouse.
Manage the open window with the mouse
Double-click the top title bar of any window to maximize a window or if it is already maximized resize it to a window. You can also double-click the icon for the window in the top-left corner of the window to close that window.
Move the mouse with your keyboard
Instead of using the mouse that came with your computer you can also enable Windows to use the number pad as a mouse.
Customize your mouse
Finally, if you have a mouse with more than two buttons, installing the included mouse software will allow you to customize the mouse even more. For example, if you don't use the side buttons to move back and forth in a web page change it to something you do more often, such as switching between open windows or opening the calculator.

Create a Windows e-mail shortcut

"Facebook to charge" and "Microsoft free money"


"Facebook to start charging money soon", "With each person you forward this e-mail to Microsoft will send you money", and "Lottery award notifications" are all examples of chain e-mails and Internet myths that have been floating around the Internet for years.
