How to spot an email hoax

The Internet is a great way to share information, but also to spread lies and mischievous nonsense. When you get an unsolicited email, these warning signs, from urbanlegends.about.com, should ring alarm bells:

1. The text was not originally written by the person who sent it to you.
   
2. Phrases such as "This is NOT a hoax..."
   
3. ...Or "Forward this to everyone you know."
   
4. Overly emphatic language or heavy use of CAPITALS and exclamation marks!!!!!!!!
   
5. Language that seems more geared to persuade than to inform.
   
6. Claims to offer important information you've not heard before from legitimate sources.
   
7. Subtle jokes that might suggest leg pulling.
   
8. No reference to outside sources nor links to websites with corroborating information.

First e-Impressions

Few careers can now do without email. How effectively do you deal with it? Take this true-or-false quiz to find out!

1. Emails should be short.
   
2. The subject line should be short.
   
3. All messages should be marked urgent so people will read them.
   
4. You should respond to email messages within 24 hours.
   

Answers:

1. True. People don't have time to read pages of material on a screen. If your message is longer than screen-length, send it a different way.
   
2. False. With so much spam around, many people won't open an email unless they know who it's from or the subject is clear. Writing hi, or leaving the subject line black, leaves the reader confused.
   
3. False. People will know you always do this and won't consider your e-mail urgent, even when it is.
   
4. True. If you don't have the info, send an email to acknowledge you got their message and let them know when you'll have the info.

Speeding up a sluggish computer

Steps to take before spending money on costly upgrades.

Empty the trash. Files dragged to the trash icon may be out of sight, but they continue to eat up valuable space. Only when the trash is emptied is space freed up.

Restart your computer. Even when you quit a program, large ones may continue to siphon off memory. Restarting (or "rebooting") adjusts this problem.

Fix fragmented files. Over time, files on your hard drive may become fragmented, i.e. a file may be broken up into pieces and written on different far away locations on the hard disk drive, requiring more time to read the file from the hard disk drive. Most PCs come with a defragment program. In Windows you can find it under Programs > Accessories > System Tools > Disk Defragmenter.

Purge old e-mail files. Many e-mail programs save copies of every message you send. Empty or reduce this backup file to free up hard-drive space. If necessary, ask your e-mail service to help locate the files.

Switch off start-ups. Programs that support instant messaging and calendars begin running as soon as you start your computer and use up its resources. You're better off turning them on as needed. » Continue reading

Straighten out your cyberkids

A recent Australian study found that 60% of children using computers at school showed early signs of repetitive strain injury. Here are some at-your-desk exercises for young PC-users. (Do them gently; if you feel pain see your doctor.)

1. Stretch your arms above your head and spread your fingers. Then lower your arms so they're straight out in front. Hold for a few seconds.
   
2. Push the bottom of your right palm against the top of your left palm, so you feel a stretch along the underside of your left forearm. Repeat on the other side. Now do it pushing on the backs of your palms.
   
3. In a chair with your back straight, look over your right shoulder. Then slowly move to look over your left shoulder. Go back to the center and nod slowly three times. Then turn your head in a "no" motion three times. Finally stretch as if laying your head on each shoulder.
   
4. Keep your hips forward and turn to look behind on each side, placing your arm across the back of the chair, stretching your back.
   
5. Push your chin forward to stretch the jaw and neck.
   
6. Sitting, roll each shoulder forward and around then back and around. Then lift each shoulder up to your ear and down.

Cat walk on the keyboard

Cats and computers don't mix. Any cat owner will tell you kitties like to walk, jump or sprawl on keyboards in just such a way as to uninstall software or even crash your computer. "For some cats, keyboards are like New Age sandals with rubber nubs pointing upwards onto their soles. Shiatsu for cats, maybe," says computer programmer Chris Niswander, inventor of PawSense, a program that can sense when a cat depresses multiple keys. One or two paw steps are enough for the software to block access to computer and emit anticat sounds -- a variety of annoying noises performed by Niswander. You can also record your own message such as "Bad kitty!"

Remedy for falling asleep while at the driving wheel

Vehicles of the future may keep an eye on their drivers, rousing you if you start to nod off, thanks to new technology that can scan your face for signs of drowsiness.

FaceLab uses two cameras built into the dashboard to identify key points on your face (it's unfazed by sunglasses or a head turned to one side), creating a 3D picture which it compares to a computer model. By analyzing the movements of your head, the rate you blink and the angle of your gaze it monitors progressive drowsiness. If you're in a danger of falling asleep, the system could trigger alarms or a flashing red light-which could refuse to stop until the card did. If the system works and is adopted by the industry it could help save the innumerable lives lost each year from falling asleep at the wheel. » Continue reading

Getting the most from AA batteries

It turns out that batteries aren't as "perishable" as we thought. "You can buy batteries in value packs and store them up to five years witout fear that their energy wll drain," says Mark Connelly, Consumer Reports director of appliance testing. Just don't toss loose batteries into a shoebox with metal objects. They can touch and lose power. As for putting batteries in the fridge, the chill does not preserve or extend their life by much, Connelly says. Here's a battery-buyer's guide:

Alkaline: Single-use battery best for low-drain electronics such as remotes and many toys.

Premium alkaline: Lasts longer than regular alkalines. Good for high-drain devices such as digital cameras.

Rechargeable nickel-cadmium: Less powerful than alkalines but can be recharged. Most suited for remotes, toys and small radios.

Rechargeable nickel-metal hydride: Ideal for high-drain items thanks to its extended life. » Continue reading
