Michael asks, "The rear-facing camera on my iPhone is foggy, but the front-facing camera is perfectly clear. What can I do to fix it?"

It's fairly safe to rule out any software problem with your phone, especially since you said the front-facing camera is working properly. So, it has to be one of three causes: you either have a bad scratch or scratches on the lens of your camera or you have moisture inside your iPhone, or there is the possibility that your lens is just dirty.

Ryan writes, "I am thinking about getting a TV for our apartment for Christmas. The question is, how big should it be? I would like a bigger TV, but our apartment is pretty small."

Smart question, Ryan. There are actually recommended guidelines for how large your TV should be depending on how far you sit away from it. If you are really hankering for a larger TV, we’ve got great news for you: you can probably get a much bigger TV than you would have expected!

Saturday is the day the Obama administration promised it would have HealthCare.gov working smoothly for the majority of people who need to sign up for health insurance.

As the Obama administration scrambles to fix the glitch-plagued site, experts are beginning to worry about another problem that may further impair the rollout of the Affordable Care Act.

Britt writes, "So, I have kind of a weird problem. Touchscreen phones don’t work very well for me. When I touch the screen of a smartphone, it often doesn’t recognize that I’ve touched it. The strange thing is my mom has the same problem with touchscreens. We’ve always figured it had something to do with our circulation or something, but neither of us has cold or clammy hands. Why don’t touchscreens like us?"

As federal tech launches go, it's not just HealthCare.gov that didn't take off. A report from IT research firm the Standish Group finds that 94 percent of federal IT projects come in late, over budget or get scrapped completely.

President Obama focused on the issue of procuring technology for the federal government in a recent interview.

Alex asks, "You mentioned a few weeks ago that people could back up their information to 'the Cloud'. I hear that term thrown around a lot, but what does it actually mean? What is 'the Cloud'?"

That’s actually a great question, Alex. The funny thing is, most of us have actually been using "the Cloud" for years now. Anyone who has ever used an email service like Yahoo, Hotmail, or Gmail has already used the Cloud. For a normal, non-technical user, “the Cloud" is just storing your data on the Internet instead of just on your home computer.

Jamie writes, “I recently started experiencing random pop-up ads on my computer even when I was on websites that don’t have pop-ups. Downloading a malware removal program didn’t fix the problem. Eventually I had to roll back to a clean install of Windows. How did my computer get infected, and how can I avoid this in the future?”

Getting infected with malware and pop-ups is no fun. Even though there are lots of software programs out there to clean this junk off your hard drive, these kinds of malware programs are designed to be a pain to remove.

Gary writes, "I’ve heard that you’re supposed to have a good password to keep hackers from breaking into your account, but how do I know what a secure password is? I know I shouldn’t use something dumb like 123abc but I don’t think I can remember a bunch of random letters and numbers. What would you recommend?"

First of all, there are different guidelines for home users and work users. Here are some password security basics for home users:

Commuters and concertgoers on the First Coast have two new free sources of information available on their smartphones.

On Thursday the St. Augustine Amplitheatre announced the release of a new app available on both Apple devices and Android phones.  

The app, developed and donated by New York City-based NY App Sales LLC to St. Johns County Cultural Events Division, provides info including venue events listings, links to direct ticketing and music from artists performing at the amplitheatre.

There are no physical signs you've entered the National Radio Quiet Zone, a 13,000-square-mile area that covers the eastern half of West Virginia. But the silence gives you a signal. Somewhere around the Virginia-West Virginia state line, the periodic buzzes and pings of our smartphones stopped.

"Zero [service]. Searching," said photographer John Poole, who traveled with me to the zone.

David writes, "The other day I received a direct message on Twitter from a colleague of mine that said, 'Is this what you were talking about?' and a link to a web page. Like a dummy, I clicked the link. It took me to some random web page that didn't have anything to do with me. I messaged him back, and he had no idea what I was talking about. Then, I started getting messages from other friends on Twitter asking what I was talking about. Somebody hacked our Twitter accounts! What can we do to fix it?"

Michael asks, "My son recently gave his mother an iPad as a birthday gift. He bought it earlier this year, but he decided he wanted an iPad mini instead. What's the best way to delete all of his data and accounts on the iPad, and get him moved over to the iPad Mini without losing all of his emails, contacts, music and apps?"

Sales of its new iPhone 5s and 5c models have surpassed other iPhone releases and exceeded initial supply, Apple says. The company says it has sold 9 million of the phones since their launch on Friday and that "many online orders" will ship in coming weeks.

"This is our best iPhone launch yet — more than nine million new iPhones sold — a new record for first weekend sales," Apple CEO Tim Cook said in a Monday press release. He added that "while we've sold out of our initial supply of iPhone 5s, stores continue to receive new iPhone shipments regularly."

Emily asks, "My coworker lost her iPhone at work the other day. She was in a panic because she thought that someone had stolen it. Fortunately, someone turned it in later the next day. I thought I heard there was some way to find an iPhone if you lost it? Is there a way, and if so, how does it work?"
