Leo called in and said his work computer got a virus. Everytime people log onto his website now, they get that FBI symbol. Leo says that hacking websites is the number one way hackers can get onto home computers. It's possible that his work website has been hacked because it isn't up to date and has security vulnerabilities.
Johnny Jet is in Cambodia this week and he says that they require fresh US dollars to pay not only for your visa, but also cab fare. If they're torn, they won't accept them. Leo says that if he's only traveling for a week or less, they just stay at one site and see it all, rather than try and waste time traveling around the countryside.

It allows up to 9 people and they can do live Hangouts On Air and then save it right to YouTube. And it's free. But he'd be limited to nine people at this point.
Our memory may be negatively impacted by the instant access of information online. The authors pose one simple example: Ask yourself how many countries have flags with only one color. Regardless of the answer, was your first thought about flags? Or were you thinking about where you could find the answer? In the old days, you may have thought about all of the flags that exist and which ones have one color. Now, you may be thinking about your Google search term. This is called "transactive memory" and it's been going on long before the internet.
Tina is a software instructor and her Dell Laptop is dying. So she bought an Asus 10" laptop and now her Asus is being recalled. She's returning that and now she's got no backup laptop to do her job. She's looking for something small that she can use.
Leo says that an ultrabook is ideal for Tina. It's thin and light, and has a decent sized 13" screen. It's also great on battery life. Tina's budget is $500, so Leo advises Lenovo's business class laptops.
Joe wants to put his DirecTV on his boat. DirecTV says they can do it, but he doesn't believe them. Leo thinks that if he's in the harbor and there isn't a lot of movement, then it could be possible. But since boats move up and down according to the tides, Joe will likely lose that satellite connection often. It's not a good idea, especially for internet access.
Chris has a Wi-Fi issue in his house, and he's been told that he can only have three Airports in his home because it would cause problems. Leo says there shouldn't be a limit with WDS if the other Airports are just passing along the data and extending the network. If they're all on the same channel, then the limit will probably be in force since collisions could occur. The trick is to get the channels that are overlapping as far apart as possible, around 100 feet away. This is to reduce Wi-Fi congestion. It can work, but it could be a bit less reliable.
At about 3 am Sunday morning, a 6.0 magnitude earthquake struck Northern California. Leo awoke from his bed and immediately went to Twitter, where he found tons of breaking news. Leo says that if you want to know what has happened, Twitter is the place to go. CNN didn't announce the news of the earthquake until 40 minutes later, while Twitter had the magnitude, epicenter, and other details within a few minutes. Leo says that Twitter is great for breaking news because you get details practically as they happened from people who are witnessing it. It's like the first draft of history.
Karen wants to know how much data she uses on Comcast because she's thinking of switching to cellular data only. Karen can log into her Comcast account online and it should tell her how much data she uses.
Mike is looking for a car video unit that he can install. He's building a small fleet of rental cars and wants to include them as a feature. Leo says there's a lot of places to buy Chinese consumer electronics, like eBay, and they're cheap. But the quality varies considerably and he'll have little recourse if they go bad.
