Xfire safety laser light makes a portable nighttime bike lane

Here in Albuquerque, we have a 5-feet-to-pass law. You need to give cyclists that much room when you go around them in a car. It's easy to visualize when you have marked bike lanes, but some drivers push the limits on unmarked streets, especially at night.

If bicyclists carried their own bike lanes with them, it might help alert motorists to give them proper room. That's where Xfire's clever Bike Lane Safety Light comes in. The light uses two 5mW red lasers to create bike lane markings and five red LEDs for increased visibility overall. … Read more

How to keep smartphone-using kids safe

Kids can't do it alone. Parents can't do it alone.

Making sure children have safe access to technology requires the participation of hardware vendors, app developers, service providers, educators, industry leaders, and the media. But ensuring the safe use of tech products by children begins and ends with parents.

They're the ones who gauge how much technology the child can handle, who establish the parameters for the child's use of computers and phones, and who keep a close-but-not-too-close watch on how the child is using the technology.

Monitoring your children's use of the family computer … Read more

How Instagram became the social network for tweens

I just learned that my 12-year-old daughter is an app scofflaw. So, in fact, are the hordes of her fellow tween-agers -- kept off Facebook by their well-intended parents -- who have turned to Instagram as a seemingly innocuous social-network workaround.

As it turns out, just like Facebook, you technically have to be 13 to have an Instagram account. And, just like Facebook, Instagram is more or less a social network, dark sides included. Kids post photos, their followers comment... and then those not invited to said birthday party or shopping excursion get hurt feelings.

Many of us adults discovered … Read more

'Talking' smart cars embark on pilot test on city streets

The U.S. government is launching a project in Michigan where 3,000 "smart cars" will be able to "talk" to their drivers.

No, it's not some Knight Rider-esque KITT scenario, it's actually specialized technology that's equipping cars with Wi-Fi to see if such communication can make the roads safer.

"Vehicle-to-vehicle communication has the potential to be the ultimate game-changer in roadway safety," administrator David Strickland from the Department of Transportation's National Highway Traffic Safety Administration said in a statement, "but we need to understand how to apply the … Read more

AT&T cuts frequency on cell towers that jammed police radios

AT&T has temporarily disabled a frequency emitted by 16 towers that were found to be interfering with police and firefighter radio communications in Oakland, Calif., the San Francisco Chronicle reported today.

The towers were causing radio failures, particularly when a police car was within a quarter to half a mile of one of them, said David Cruise, Oakland's public safety systems adviser.

After the U.S. Federal Communications Commission confirmed the interference, AT&T shut down the 850MHz frequency for 2G customers on the towers last Friday, but the carrier left the 1,900MHz and 700MHz … Read more

U.S. report: FCC's cell phone radiation guidelines outdated

The Federal Communications Commission should review its cell phone radio-frequency (RF) exposure limit, which was set 15 years ago, because it does not include testing for potential harm from holding phones directly against the body or factor in the latest research, a government report recommended today.

When the RF exposure limit of 1.6 watts per kilogram specific absorption rate (SAR) was established in 1996, phones were bigger, bulkier, and carried in holsters outside of clothes and not in pockets, said Marcia Crosse, director of health care at the U.S. Government Accountability Office (GAO) and co-author of the report. … Read more

MetaCert aims to block porn throughout the home (podcast)

There are lots of tools out there to help parents keep their kids away from what's typically considered inappropriate online content. Most, however, run on PCs and Macs, which means all bets are off if, for instance, a child surfs via a smartphone or a tablet.

MetaCert has a different idea. It's now beta-testing a server-based porn filter parents can set up to automatically block access to pornographic sites across their entire home network. It does so by hosting the filter on a DNS, or domain-name system, server -- effectively pushing the filter from individual computers into the … Read more

Those sneaky teens: What they're really up to online

If you have a teen in the home, beware: there's a good chance he or she is hiding what they're doing on the Web.

According to security firm McAfee, a whopping 70 percent of teens aged 13 to 17 have admitted to hiding their online activities from parents. McAfee found that 43 percent of the surveyed teens access simulated violence on the Web, while 32 percent view nude content or pornography.

Interestingly, parents don't necessarily think that their children are doing anything wrong on the Web. In fact, McAfee, which surveyed a total of 2,017 people, … Read more

Can social networks protect your kids?

Social networks catering to adolescents have a serious trust issue -- and justifiably so.

Location-based flirting app Skout and teen social-networking game Habbo were hit by reports that adults allegedly used their services to sexually prey on underage users, causing both sites to temporarily restrict access this week.

The incidents serve as a reminder of the potential risks that arise when a minor logs on to any social network, an issue that has gotten even more scrutiny with Facebook looking to possibly open its doors to users under 13. More importantly, it reinforces the notion that no network is truly … Read more
