How can I be secure on public Wi-Fi?

Episode 1496

Jose from Ontario, CA
Tiny Hardware Firewall

Jose is concerned about being snooped on when using public Wi-Fi. What can he do to protect himself? Leo says the first thing to do is turn on hard drive encryption. That will keep his data safe should his laptop get stolen. But for just being on a public Wi-Fi, VPNs can be beneficial. VPN stands for "Virtual Private Network," and all of the traffic that goes through it is encrypted. It's like a secure tunnel through the internet. Most web pages are encrypted now, though, so no one could see his activity on those sites anyway.

Is condensation in an airplane normal?

Episode 1495

Mike from Maine
Johnny Jet on a plane

Mike is a commercial pilot and he called in to talk about Johnny Jet's tweet about mist in the airplane cabin. Mike says that airplane mist happens a lot in humid climates when the cold air from the airplane's AC meets the warm air of the cabin. It's very normal, and only happens when the plane is at the gate and hooked up to an air conditioner to keep boarding passengers cool.

Can I transfer my domain name?

Episode 1494

Lee from Panama City, FL
Address bar in browser

Lee wants to know how to register his domain and DNS so he knows he owns it. Leo says that ICANN is a non-governmental organization that handles the DNS "phone book." They maintain 13 main DNS name servers, and his domain name needs to be on one of those servers. He'll have to go to a registrar that's been approved by ICANN. GoDaddy is one such registrar, but Leo isn't a fan of it. He prefers Hover. If he wants to change registrars, he can do that. But he'll have to jump through a hoop or two to do it.

Johnny Jet on Travel Tech

Johnny Jet

Tip of the week: You can save money traveling to Europe by flying to a secondary city. But you have to pack light or you'll get socked by extra baggage fees. You can fly into Milan, instead of Rome, and then take the train and save thousands. Go to Google Flights and put in your departure city. Then you'll get a map that shows you different destinations and prices. Kayak does it too. Also plan to leave plenty of time in between flights. Even spend the night. Another great flight is Fly 4 Free.

Why doesn't my Gmail work?

Episode 1493

Jerald from San Diego, CA
Gmail logo

Jerald is having issues with Gmail. It comes up, but when he tries to open an email, it goes blank. It works when he logs on somewhere else, though. Leo says that Gmail is a web application that runs Javascript. So it may be that his browser is blocking that. Ad blocking software may also be doing it. He should try disabling his ad blocker and see if that works. Click the on/off switch at the top of the page and see if it loads up.
