What's the difference between IMAP and POP3?

Mike from Portland, MN

Episode 1283

Mike uses Thunderbird with POP3 and wonders if he should use IMAP. He doesn't know anything about it, though. Leo says that Thunderbird is the best email client out there and Leo uses IMAP with it. POP (post office protocol) will download his email and then remove it from the servers. IMAP, by contrast, will allow him to see the email and keep copies of it on the server. This is beneficial because people use more than one computer and mobile phone.

What are the best battery powered security cameras?

Episode 1282

Daniel from Las Vegas, NV
Netgear VueZone Wire-free Video Monitoring System

Daniel wants to know about wireless home security cameras. He's looking for a good 5GHz camera that can be battery powered. Leo says that battery powered cameras aren't always on -- they use motion detection.

NetGear's VueZone is a good brand. 5GHz, on the other hand, isn't as good as 2.4GHz, even though it's less congested. The higher you go in frequency, the more likely the signal will bounce around and get interference. The batteries do last for a year in those cameras, though.

How can I get my Yahoo Mail password?

Perry from Riverside, CA

Episode 1280

Perry has his life on Yahoo and he can't find his password. He wants to reset it, but it requires a cell phone number and his cell phone doesn't work. Leo says that with this unique situation, the solution would be to write Marissa Mayer at Yahoo and ask if she can help. She'll likely assign a high level tech support person to help. But there's a good chance that he won't be able to get it unless he can remember the password.

Where is the certificate for an encrypted file?

Yogi from Belmont Shores, CA

Episode 1279

Yogi wants to know about file encryption. He encrypted a file and then wanted to take the key off and put it on a USB key, but he can't find it. Leo says that the certificate is the key. If he can find the certificate, he can copy it. If he were to copy the file without the certificate, no one would be able to get to that file. The idea is that he's encrypting the file so that it can't be opened by anyone who isn't himself, and the way he can prove his identity in this case is by logging into his system. Someone would have to have both his login and the password to access that file.

How can I create my own internet television channel?

Scott from Orange County, CA

Episode 1279

Scott wants to get into internet TV. Leo says he's been doing it for ten years, and it's still not as widespread. But it's gaining in popularity. In fact, most TVs sold are smart TVs that are connected to the internet and allow users to stream services like Netflix, Amazon, and Hulu. That's IPTV as well. He's heard about the TriCaster and knows that Leo uses one. With an IP camera, does it really make it more like CNN? Leo says it does. But it's dependent on bandwidth. Leo's audience is as big as it was in the days of Tech TV now.

Episode 1278

William from Capistrano Beach, CA
Apple Airport Extreme

William has an Airport Extreme router that disconnects 3-4 times a day. Leo says that's not unusual with routers. They're basically just a dumb computer that sometimes crashes.
