Taking care of personal information

The reason why social networking sites are so popular is because they make it easy to share information with so many people: it’s easy, for example, to let your friends see your holiday photos before you even get back home, or, when you do get home, you can instantly look up the profiles of the people you met on holiday and send them a message. But it’s important to remember that any information you post on a site could be public and may be seen by lots of people.
This means you have to be careful about what you reveal about yourself to other users. If information you post is seen by more people than you expect, this could pose a risk to your privacy or even your personal safety. Once information is ‘out there’ you might not be able to control what happens to it: your profile may be seen by thousands of strangers, parts of a website may be ‘public spaces’ so what you say on them is also public, and not everyone will agree with what you write. Also, it can be easy for others to copy your pictures, even alter them, and send them to people you don’t know.
So, before you create a profile, post a picture or tell the online world what you got up to today, have a think about the following and consider whether you are being as safe in the online world as you would be in the offline world.

Don't slouch!

Find yourself getting tired easily when using your PC? It might be that you're in an uncomfortable environment.Make sure that you use a chair with good lumbar support,that you have sufficient place to rest your palms and that your eyes are aligned to the top of your monitor and at least 45cm away - these tips allow you to sit comfortably with reduced strain on your back,arms and neck.Oh,and make sure your room is brightly lit and that you're not sitting with your back to a window - this reduces glare and keeps your eyes happy.

Nurse your batteries

If you are using AA or AAA sized rechargeable Ni-MH batteries with your electronic devices,there is a temptation to recharge them even before they run out of power.Do not do it.Ni-MH batteries have what people call the "memory effect".This means that the battery eventually remembers how much charge it used and will only provide that same amount the next time you use it(i.e their battery life decreases).Instead,always keep two sets of batteries - only recharge the first set when it runs dry,replacing them with the second set to keep your devices running.Alternate between the two sets.(Note:this doesn't apply to lithium-ion batteries.

Turn off your LCD screen

Should you leave your LCD monitor on all the time? Definitely not,experts say.
Although not as susceptible to image "burn-in" as traditional cathode ray tube-based(CRT)monitors,LCDs can suffer from permanent ghost image of a screen that has been displayed for long periods of time.
so turn the monitor off when it's not in use.Doing so will also save electricity than CRT monitors but they still consume as much or more than a couple of standard light bulbs.

Revise autoplay option

By default,Windows XP works with the autoplay option turned on.That means the computer springs into action as soon as a digital camera is connected to the computer or a CD is inserted.
If the autoplay window no longer opens on its own,but a CD nevertheless starts playing,or saved images on the digital camera are displayed automatically,then in all likelihood the selection on the AutoPlay tab labelled "Prompt me each time to choose an action" is not selected.
To change the autoplay settings for a specific device,right click on the device in question in My Computer.The setting can then be adjusted under Properties.

Watch your posture

Ergonomics experts recommend that you maintain a relaxed but upright posture,without excessive bowing of your back,and without leaning your neck forward unnaturally to view your monitor.Your shoulders should be relaxed,and your arms forearms should extend straight out from your elbow,forming a 90 degree angle at the elbow.The same goes for your knees.Good posture can go some way toward preventing musculoskeletal disorders that arise from extended sitting at the computer.

Backdoor for forgotten passwords

You don't have to panic if you forget the password for your home Windows XP computer. The operating system contains a backdoor:Pressing the F8 key immediately after the computer is started lets users boot in the "safe mode".The users can then create a new password for themselves.

To save or Not to save

Think carefully before you save money in this way.Manufacturers will generally refuse to service a printer in which third-party ink has been used,regardless of whether the ink is the cause of the problem.Ink does,in fact,cause many of the problems encountered by inkjet users.

Practical Tips

Watch this post, am toying with the idea of sharing with you the tips that I come across. You see,I have these useful informations stored and they're taking up space, and if I continue to store them, I may have to trash them one day,and all these good tips would have been lost forever.
I have been thinking it would be a good idea to achieve them here for future reference.
