PC World - A vulnerability in a Web server contributed to the attacks on some 300 Web sites in Lithuania earlier this week, a computer...No tag for this post.

Police in the 1970s urged citizens to "drop a dime" in a pay phone to report crimes anonymously. Now in an increasing number of cities, tipsters are being invited to use their thumbs -- to identify criminals using text messages.

Police hope the idea helps recruit teens and 20-somethings who wouldn't normally dial a Crime Stoppers hot line to share information with authorities.

"If somebody hears Johnny is going to bring a gun to school, hopefully they'll text that in," said Sgt. Brian Bernardi of the Louisville, Ky., Metro Police Department, which rolled out its text-message tip line in June.

Departments in Boston and Cincinnati started accepting anonymous text tips about a year ago. Since then, more than 100 communities have taken similar steps or plan to do so. The Internet-based systems route messages through a server that encrypts cell phone numbers before they get to police, making tips virtually impossible to track.

In Louisville earlier this week, Bernardi's computer displayed a text message from a person identified only as "Tip563." It read: "someone has vandalized the school van at valor school on bardstown rd in fern creek." The note also reported illegal dumping in a trash container and in the woods.

"It's obvious that the future of communication is texting," said officer Michael Charbonnier, commander of the Boston Police Department's Crime Stoppers unit. "You look at these kids today and that's all they're doing. You see five kids standing on the corner, and they're texting instead of having a conversation with each other."

When Boston adopted the system last year, the first text tip yielded an arrest in a New Hampshire slaying. In the 12 months that ended June 15, Boston police logged 678 text tips, nearly matching the 727 phone tips during the same period.

Earlier this year, a text tip led to the arrest...No tag for this post.

Unable to strike a deal on its own, Microsoft Corp. reportedly is hoping to snap up Yahoo's online search operations with the help of News Corp. and Time Warner Inc.

The latest twist in Microsoft's convoluted courtship caused Yahoo's shares to rise more than 3 percent in Wednesday's sinking stock market, even though the chances of a deal getting done still seemed remote.

If nothing else, the enthusiastic reaction to the unconfirmed report in The Wall Street Journal served as another reminder that investors want Yahoo to pursue a different path than the one mapped out by Chief Executive Jerry Yang.

And that could be bad news for Yang, who started Yahoo as an Internet directory 14 years ago. Unless he can sway shareholder sentiment before Yahoo's annual meeting Aug. 1, Yang could lose his job in a boardroom coup being attempted by investor Carl Icahn.

Recognizing Yahoo's vulnerability, Microsoft is trying to recruit News Corp., Time Warner's AOL or other media partners to put together a joint bid that would slice Yahoo into pieces, according to the Journal. The story cited undisclosed people familiar with the discussions.

Microsoft declined comment Wednesday. A Yahoo spokeswoman didn't immediately return a call seeking comment.

Under the reported breakup plan, Microsoft would emerge with Yahoo's online search operations -- the main object of the software maker's desire since it began stalking Yahoo as long as ago as 2006.

After the two sides couldn't agree on a price, Microsoft withdrew a $47.5 billion bid to buy Yahoo in its entirety in early May.

Just two weeks later, Microsoft offered to pay $1 billion for Yahoo's search engine and invest another $8 billion for a 16 percent stake in Yahoo's remaining business.

Yahoo rejected that offer, too, and instead forged an advertising partnership with Google Inc., whose rapid growth prompted Microsoft's bid for Yahoo...No tag for this post.
