Readers of FHM magazine recently named Britney Spears the world's sexiest woman, but how good does she look in high definition? Decidedly unsexy, according to television industry analyst Phillip Swann.

He maintains a list of stars who look great in the high resolution images of HDTV -- and those whose flaws are revealed in the harsh light of high definition reality.

Swann says that in a recent HDTV television concert, Spears' face looked "bumpy and puffy." HDTV's super-clear picture shows Michael Douglas to be wrinkly and old, while his wife, Catherine Zeta-Jones looks terrific -- like a porcelain doll. HDTV flatters George Clooney and Charlize Theron, but it's less kind to Robert De Niro and Renee Zellwegger.

Swann says Hollywood makeup artists are trying to adjust to the new world of HDTV, but they can only hide so much.

SWANN: The Hollywood dream machine -- those glamour image consultants who sell on who's pretty and who's not -- put a lot of marketing dollars into trying to create a perception that certain people are beautiful. Why do they do that? Because if they can create that perception they make billions of dollars. Britney Spears is making hundreds of millions of dollars on the fact that people think she's gorgeous and sexy, when in real life she isn't. And so that is a real eye opener and exposes what Hollywood is doing with certain people. But when you talk about people who are really physically beautiful in real life as well as in HDTV, you have a greater appreciation of that.

We're eliminating a whole class of potential stars who are not gorgeous but can be made to look gorgeous?

SWANN: Exactly. Now it's people who are truly beautiful who will be most successful. It will be more difficult for the Hollywood glamour machine to create images, which they have done for decades. In HDTV you got to see people for who they really are, and the Hollywood images consultants are at a loss. They're running scared.

Maybe the effect will be that the public will develop a more realistic, healthy sense of human beauty?

SWANN: Since I reported that Cameron Diaz doesn't look as good in HDTV and she's had an acne problem, I've had people tell me they have a greater sense of appreciation for her now, because they can now identify with her. She's not this incredibly gorgeous, beautiful glamorous super star that she's portrayed as. She truly is the girl next door, because the girl next door might have an acne problem, too.

File sharing may not be responsible for declining CD sales.

Researchers at Harvard Business School and the University of North Carolina, Chapel Hill say they've found that sharing of digital music files on peer-to-peer networks like KaZaA has only a minor effect on the sale of compact discs.

The report counters the music industry's central theme in its war on digital piracy. The music industry has blamed file sharing for a prolonged decline in CD sales.

The report says that file sharing actually appears to boost the sales of popular albums by the likes of Brittney Spears a little, while slightly depressing the sales of CDs from lesser-known artists.

Harvard associate professor Felix Oberholser says the study compared actual downloads of music files to store sales of CDs during the latter part of 2002. He says people who shared files likely would not have bought the albums that they downloaded.

OBERHOLZER-GEE: Most of what we know about the effect of file sharing on CD sales comes from surveys. You would ask people, "Do you download music?" Then you would ask whether or not downloading music has changed behavior. The problem with all these surveys, in particular after people realized file sharing was illegal, is that you couldn't be too sure whether everybody is willing to reveal what they do and what they think. The study we did is unique in that we have log files from servers that facilitate downloading. And so we can actually see what people download and we can see if albums that are downloaded more often -- whether their sales change in any way in response to downloading.

What did you find in that regard?

OBERHOLZER-GEE: The average effect of file sharing on sales is pretty much zero. We cannot find a negative impact. We have a number of statistical models, and even if we take the most pessimistic one, the negative effect that we find is so small that the big drop in sales in the 2000 to 2002 period cannot be explained by file sharing.

It's such a tempting connection to make, and one that the recording industry has wanted us to make. Even though CD sales are dramatically down while downloading is dramatically up, there's no connection?

OBERHOLZER-GEE: To make the argument ring true what you would have to see is that the types of music that are shared most often are the types of music that lose the most sales. This is not what we see in the data.

The Recording Industry Association of America (RIAA), the trade group representing the music industry, denounced the report's conclusions. It released the following statement: "Countless well-respected groups and analysts, including Edison Research, Forrester, the University of Texas, among others, have all determined that illegal file sharing has adversely impacted the sales of CDs."

Spyware, also called adware, is any software that secretly collects information about a computer and transmits the information to a a third party, usually for advertising purposes. It often leads to an annoying barrage of unwanted pop-up ads, and in sufficient quantity can damage your computer.

Dwight Silverman writes about computing for the Houston Chronicle.

SILVERMAN: Spyware can generate pop-ups that it pulls from a Web site or an advertising service. Sometimes these pop-ups can show up even when you are not browsing. The spyware runs in the background and brings you advertising pop-ups. I have seen some pieces of spyware that, when you click on something that generates a pop-up, instead of what you wanted you get a dozen other pop-ups that are advertisements. It can install unwanted search bars in the tool bar of your browser so it forces you to use their particular search engine, which in turn generates more advertising.

Where does spyware come from?

SILVERMAN: Usually it comes from Web sites that invite you to download something, or if you download a piece of software that appears to be useful and is usually free. The way they're able to afford the development of that software is usually to sell advertising within it, or to have some other process in it that talks to advertisers. You can also get spyware by going to a Web site that pops up what's called a "browser helper object certificate." It looks almost like a little stock certificate. It says, “Do you want to install this product that will improve your search function and get you free porn?” And yes, some of them say that. Hopefully most people will click no. But some people will click yes. And that installs the spyware.

What do the purveyors of spyware want from me?

SILVERMAN: They want to know what you are doing on the Web. They want you to look at their advertising. And they want you to buy their products. Why do they want to know what I'm doing on the Web?

Why do they want to know what I'm doing on the Web?

SILVERMAN: There is spyware that will target ads at you depending on where you go. So let's say, for example, that you're fond of going to gaming sites. They might pop up some ads for games.

How can spyware actually hurt your computer?

SILVERMAN: If you have enough of these programs that are talking to other Web sites, popping things up and hogging your bandwidth, they can really slow down both your Internet connection and the general performance of your PC. In fact, that's how most people realize they have spyware. They think the pop-ups are just coming from surfing the Web. They don't realize that their machine is slowing down because it is clogged with spyware.

Letters that soldiers write home help future generations better understand the nature of warfare and the sacrifices made by the men and women who serve the country. But with the Internet available to most troops in Iraq, war correspondence is changing. E-mail is fast replacing handwritten letters.

Today we speak with Andrew Carroll, editor of War Letters: Extraordinary Correspondence from American Wars. That book served as the basis for the film "War Letters" that aired on the American Experience on PBS. He's in the middle of a trip to more than 30 countries, talking with soldiers and collecting their correspondence. We reached him in Beijing.

It used to be that handwritten letters were about the only practical way for soldiers at war to correspond with family or friends back home. But today in Iraq, a year after the war began, most American troops can slip into a military-run Internet cafe to send and read e-mail, surf the Web, or place a call to the states over an Internet telephone.

Each cafe is equipped with about 20 Gateway laptop computers and four "voice over IP" phones.

The Linux Users Group of Baghdad is asking Americans to donate how-to books to help build a new computer infrastructure in Iraq.

The group says computers and software are easier to come by than instructional books. Would-be Iraqi geeks are looking for books on Linux, the open source operating system that serves as an alternative to proprietary programs like Windows. They also need books about other kinds of open source software, and about HTML, the programming language of the Web. The goal is to encourage the development of a technology industry that's not dependent on U.S. companies.

Linux, the computer operating system that many corporations are adopting as a vastly cheaper alternative to Windows, is the subject of two new lawsuits.

Linux is open source software, meaning that programmers from around the world contribute to it. Linux code is free, or can be purchased in more user-friendly, packaged versions.

Utah company SCO is laying claim to Linux, saying parts of it have been lifted from Unix. Unix is an operating system created by Bell Labs in the 1970's that's now owned by SCO. SCO has expanded its legal campaign, suing retailer AutoZone and carmaker DaimlerChrysler over their use of Linux.

Stephen Shankland, a reporter for CNET News.com, says the lawsuits could have far-reaching implications.

It's "Super Tuesday," when voters in ten states cast their primary ballots. It could turn out to be a big day for one of the Democratic contenders, but it will certainly be a big day for electronic voting. Voters in California, Georgia, and Maryland will cast their votes with a touch-screen. After the 2000 election Congress authorized funds for states to upgrade to electronic voting, but it's still a controversial technology.

In Maryland, officials are trying to shore up confidence in the new machines. Measures include tamper-proof adhesive tape to prevent anyone from fiddling with their programming or electronics. We talk with the state's top election administrator. (Jeff Horwich guest-hosts.)
