The right way and wrong way to use Twitter

"Thank you for sharing" takes on an entirely new meaning when using social media. Most of the people who use Twitter, Facebook, and other social networks intend their posts to enlighten, amuse, or inspire their friends and followers. It doesn't always work out that way.

For businesses, Twitter is primarily about customer relations, but this can backfire, too, as Customer Think's Trish Miller points out in the Top 10 Twitter Mistakes of 2012.

Free services make Gmail, Google Drive, Google search more private

It's no secret that any information you provide to a Google service is no secret.

When Google changed its terms of service last year, the company granted itself and any other company it chooses complete, unfettered access to anonymized (we hope) versions of all the messages you send and receive via Gmail, all the files you upload to Google Drive, and all the terms you enter in the Google search box.

As CNET's Rafe Needleman reported in April 2012, Google's rights go beyond simply perusing your personal information. Google's terms of service include the following:

Google's Schmidt: The Internet needs a delete button

NEW YORK--The Internet needs a delete button, Google Executive Chairman Eric Schmidt said Monday.

Actions someone takes when young can haunt the person forever, Schmidt said, because the information will always be on the Internet. He used the example of a young person who committed a crime that could be expunged from his record when he's an adult. But information about that crime could remain online, preventing the person from finding a job.

"In America, there's a sense of fairness that's culturally true for all of us," Schmidt said. "The lack of a delete … Read more

Samsung Galaxy S4 earns Pentagon security nod

Samsung is now clear to start pitching its new flagship phone to the government.

The handset maker announced Friday that its Knox-enabled mobile devices have been approved by the Pentagon for government use.

If you run an online business, ensuring a smooth transition in the event of your demise becomes even more important. To ease the burden … Read more

See how beautiful a DDoS attack can look

We've all heard of a distributed denial of service (DDoS) attack and know what it is: when a person or people attempt to take down a Web site by flooding it with connection requests. These max out the site's bandwidth, making it unable to accept new requests. The attacks are usually automated and can be accomplished in a variety of ways. The loss of traffic during the attack itself, and the recovery afterward, can end up costing Web sites quite a lot.

But what does that actually look like? Well, nothing by itself; but thanks to a Web site traffic visualization tool called Logstalgia, Ludovic Fauvet, developer of the Web site VideoLAN (which created and distributes the free multimedia player VLC), managed to capture an April 23 DDoS attack on his site. … Read more
