Tech Q&A 'Supercookies,' online dating, reliable laptops, and more

Wireless companies track your browsing

Q. I thought I heard on your national radio show that wireless carriers are tracking where people go on their tablet or phone using “supercookies.” I have Verizon. Did I hear correctly?

A. No need to check yoaur hearing. Researchers found that Verizon adds a 50-character Unique Identifier Header (UIDH) to your Web traffic when you visit any website. The idea is that Verizon’s advertisers can watch for your UIDH and record when you visit sites where they serve ads. But given the way it works, any website that looks can record your UIDH, and there’s no way to opt out. AT&T, Sprint and some Canadian carriers have similar systems. The best way around this is to use the Internet on Wi-Fi, not cellular. To check to see if there is a Unique Identifier stored on your tablet or phone, click here.

Beautiful woman likes him, maybe

Q. I have started online dating. Now, I’m just a typical guy with a good job, but a smoking hot lawyer is interested in me. We’ve never chatted or met. Before this goes any further, is there any way that I can see if this picture of her is legitimate? I don’t want to get scammed.

A. Unfortunately, this happens a lot on the dating sites. People set up profiles using pictures they find online. It is possible to see if a photo appears elsewhere on the Internet. Do a Google Reverse Image Search. First, go to her profile and download her profile picture. Then, upload the photo and Google will tell you where else the same photo is online. It’s pretty slick!

What’s the most reliable laptop?

Q. I’m trying to decide on a new laptop and want a reliable brand. These things are expensive! Do you have any suggestions?

A. The Apple MacBook lasts a long time, and it can take a pounding from kids and travel. On the Windows side, ASUS and Lenovo rank high for reliability while Dell customers love its great technical support and customer service. On the other end of the scale, Acer and HP usually don’t fare as well in reliability studies. Click here for more buying advice you need to know.
