Watch Robert from Kansas City, MO Comments

Robert wants to know more about the Intel NUC. Leo says it's an ultra compact PC that looks like a Roku box. It may even be designed for home theater computing. Leo also says that Intel designs ideas like the NUC, and then gets others to manufacture it. But in this case, they are actually making the kits. He can get them on Amazon, and there's a solid review of it on PC Perspective. There were several at Computex recently, also.

Would it be sufficient for home theater? Leo says that people are looking for silence in a home theater box and a computer is anything but quiet. Leo advises using Windows and a home theater media server like XBMC.

The nice thing about it is that it can be attached it to the back of a TV. It's still a DIY project right now, though. Robert would have to add stuff to make it work, such as RAM, storage, HDMI ports, wifi, and more. $288 is a bit pricey for something he would have to buy more stuff to make it work.

Another option is OUYA. It's a game console, but he can also run Plex on it and have a home theater PC for $100.

Robert also wants to thank Leo for Security Now episode #408 on the NSA. He said it was the best episode so far. Leo says that the show was two weeks ago, but that Steve Gibson nailed what's going on.

Watch Matt from Indiana Comments

Matt is a truck driver and he recently bought the Motorola Razr. He's been having a problem with his signal going from "blue to white". When it's blue, he says, he can do everything, and white means he can only make phone calls. Matt says he'll notice that it says "4G" in blue, but when he tries to use it, it turns white, and he can't use data. He's been to Verizon several times and nothing has worked to fix it. He's even tried rooting it. Leo says if his phone says LTE, then he's getting an LTE connection, but it may not be consistent enough in Matt's area to use it. The blue and white colors, according to the chatroom, mean that Google is either syncing (blue) or not syncing (white).

Leo suggests updating the PRL or "preferred roaming list". As a trucker, he should have the most recent PRL. If that isn't helping, it could be a hardware issue, like a flakey antenna. Leo also says it may be worth the hassle to unroot the phone and then update it. That will update the radios.

He could put a custom ROM on it. He can go to Google Play and download Clockwork Mod ROM Manager. He should get the premiere version. Then he can go into it and find all the available OS's for that phone. A more up to date ROM Manager may do the trick. Cyanogen Mod is another option.

Steve called in to say that by installing a tethering program on his rooted phone, his wireless company just blocked all his data access. The solution is to reflash the SDF file and re-root. Leo says at this point he's definitely violating his terms of service.

The bottom line is, users can pay Verizon for the ability to use their phone as a hotspot, but they don't have to! In fact, Verizon paid a fine because it was tricking its customers to pay. Find out more about the details of the lawsuit against Verizon here.

Watch Bob from Atlanta, GA Comments

Bob has a network and it keeps saving duplicate images. Leo says there's a lot of duplicate elimination programs. Here's a great article on Lifehacker. This article from Tech Republic could also help.

De-duplication is risky because he could get rid of the wrong file. Server 2012 has built in de-duplication. Duplicate Cleaner is a good option because it has a "hash" which shows which file is which so he doesn't delete the wrong file.

Watch Braden from Wisconsin Comments

Whenever Braden uses his smartphone to record, the audio is terrible. Leo says that phones these days use multiple microphones and dedicates one for noise cancellation. If he doesn't have that feature, then an external microphone connected to the phone with an adapter will work. The iRig may be good for that. Audio Technica also makes a microphone that can plug into a smartphone, but it looks like a big stage microphone. The Rode iXY stereo microphone plugs into the iPhone and has stereo recording.

The best option may be just to get a dedicated Zoom H2 recorder.

Watch Ben from Barstow, CA Comments

Ben is a younger kid who has a Mac and wants to learn how to develop apps. Leo says he'll want to get XCode from the app store and download the iOS Software Developer Kit from

Leo says that learning Python is a good starting point. Learning a language that defines and solves problems will help him to think the way he needs to in order to write good code. There's a great online book called "Python for Beginners." He can also read "How to Think Like a Computer Scientist: Learning with Python". That's a good way to learn how to think like a programmer and write better software. How to Design Programs is a great website as well.

Great online portals include CodeAcademy, and iTunesU has a great class on writing iOS apps from Stanford University that's taught by Apple employees. It's free to download and watch and he'll learn a lot. Learning basic programming will help as well. If he can get his parents to pay for it, go to BigNerdRanch for summer camp. is another good place to go, as well as Scratch.

Watch Shirley from Santa Barbara, CA Comments

Shirley would like to learn how to use her computer. Leo says there's a good book in the "Dummies" series that are geared for Seniors. Computers for Seniors for Dummies is a good place to start. From the chatroom, is a great site and there's a book on it called "Is This Thing On?"

Leo also suggests that Shirley go to the Apple store and get an iPad. They'll even teach her to use it. Most people who buy computers would be better off using an iPad anyway.
