There's a time and a place for giving your PC the once-over with an online scan. CNET Editor Tom Merritt explains when and why you may want to supplement your full-time antivirus software, and offers up some good destinations for making a quick system sweep from the Web.
Here are some winter driving tips straight from the Porsche Camp4 Colorado curriculum:Cars respond more slowly on slippery surfaces. Always wait a moment after steering, braking, or accelerating to see how the car behaves before giving it more input. Visibility is greatly reduced in bad weather. Make sure you can see clearly, and turn on your headlights. Brake carefully and accelerate more gently. Get the car pointed where you want to go before getting on the gas. Be aware of reduced grip. Take corners at lower speeds. Brake sooner and longer than on dry surfaces. Apex later. Look for … Read more
For consistent 15 percent tipsters living in municipalities with a 7.5 percent dining tax, generating the perfect 15 percent tip is as simple as doubling the tax. If that's not you, Oh Arithmetic-Challenged One, you've got a bum deal. (See below for a quick computational technique.)
It's for this set, and for diners who frequently split a bill, that Ilium Software developed Tipster. The free, simple app for Palm, Windows Mobile smartphone and Pocket PC hurriedly computes your tax and total.
Tipster calculates tax in 5 percent increments up to 30 percent, and can evenly split … Read more
Winter temperatures can be tough on cars. Here are a few things to keep in mind to ensure your car performs its best in the cold:
Keep battery backup. It takes more electrical power to start a car in cold weather, yet those chilly temperatures also drastically reduce the battery's cranking power. To compensate for the increased need and reduced output, keep a good set of jumper cables or a portable power pack in the trunk.
Check climate controls. Make sure the heater and front and rear defrosters are working properly. If it takes more than a few minutes … Read more
Men and women see things differently. Take audio: A guy might be impressed with a big honkin' speaker, but a woman probably sees a hideous box. Being a guy, I might not be the most sensitive to what females want from a hi-fi, so I'm more than willing to hear about it from the other side. I stumbled upon a well-written piece on a speaker manufacturer's (Klipsch) site that does just that. It's jam-packed with great advice--and don't worry--it never even mentions Klipsch speakers. Sarah Knight's "Get Turned On: A Woman's Guide to Purchasing Audio Gear" … Read more
With all the talk of new, fuel-efficient vehicles, those of us who are still driving our regular old cars might feel left out. But there are still ways we can help save gas -- and money -- by making relatively simple adjustments to our cars and driving habits.
Change the air filter. The air filter is a crucial component to minimizing fuel use and maximizing horsepower. Bryan Gregory, director of consumer education for Advance Auto Parts, says it takes an engine about 10,000 gallons of air to combust one gallon of gas. So it makes sense, then, that the … Read more
First things first--center channel speakers do one thing really well--they anchor dialog to the screen for listeners sitting over to the left or right sides of home theaters. So if your family or friends watch movies together, I'd definitely recommend using a center channel speaker.
But for one or two people sitting directly in front of their TV a center isn't necessary, and almost always sounds less good than the left and right speakers. Center speakers tend to sound boxy, so Denzel Washington sounds like he's in a box. Ditch the center and your A/V receiver … Read more
Here's an indispensable nugget of advice: how to zip an archive so it can unzip itself. CNET editor Molly Wood shows you how to create a standalone EXE in WinZip that your recipients can open with a single click.
In this Insider Secrets video, Tom explains the ins and outs of RAM, and how RAMBooster can work its magic to relinquish trapped memory.
Speaker impedance is a confusing subject and based on the letters we get here at CNET (see below), I thought I should try shed a little light on the subject. This letter sums up the typical quandary:
"I have a bit of a dilemma that I hope you can help me solve. I have an entry level Yamaha HTIB system that I purchased a few years back and I would like to upgrade it with better speakers. I've done a lot of research and found that owning a 6 ohm receiver limits the selection of brands that I … Read more
