Todd wants to know if there's a way to get cellular data on his Microsoft Surface Laptop. Should he just turn his iPhone into a hotspot? Rich says it depends on whether or not he can hotspot with his iPhone. He'll probably have to pay an additional fee with it. Rich favors a dedicated hotspot like the MiFi Card over turning the phone into a hotspot.
Johnny says that if you fly a lot, enough to gain frequent flyer miles, it's best to stick with a single airline that you can build miles with. But if you fly infrequently, then shop around for the best deal when you do. He also says that if you get asked if you want to upgrade to "premium economy," it's a big scam. Johnny also says that airlines are now charging for gate check-in of luggage at $25 a bag or more. They'll also charge you to print your boarding pass.
Travel tip of the week - Bring a snack. You never know if the plane is going to be delayed.
Scott is very happy Apple finally joined the 4K/HDR party with the new Apple TV 4K. Even better, the Apple TV supports HDR 10 and Dolby Vision, and will be upgrading all the movies you've already bought that are in HD. But there is a problem. Your new Apple TV won't support YouTube in 4K since it doesn't support VP9, Google's ultra high definition codec.
Gloria wants to get rid of her ISP and change her email. Leo says if she's going to get rid of her ISP and its email, Leo recommends going with Gmail first and setting it up to get the email off her old email account. Her ISP is DSL Extreme. Leo says that DSL Extreme is a good provider, but if she's having issues, it may not be their fault. It may be the carrier that DSL Extreme is piggy backing on, which is usually AT&T. They have to allow them to carry it, but they don't really want to share. So they make it difficult.
Alan wants to get back into Ham radio and has heard about SDR, or software defined radio. Leo says that most modern radios are software defined and he can get back into it by just installing the software on his computer. Alan should check out EchoLink. He should also listen to Ham Nation on TWiT. He'll still need a license, but it's a good way to get back into it.
George keeps hearing about BitCoin and how much the price keeps going up. What gives it that value? Leo says nothing but sheer belief. BitCoin is crypto currency, which are essentially digital dollars that don't exist outside of a computer. You can't really take it and spend it at the local store unless the store takes it. But even a dollar bill isn't really anything but a fiat currency that the government says it's worth. The value of a dollar, or any other currency, changes all the time. It's fluid. So BitCoin is just an extreme version of that.
Jerry has been using an app to hack a neighbor's Wifi for free WiFi. Leo says that is a violation of federal law and Jerry really shouldn't be doing that. And it probably doesn't work anyway since most wifi routers are using WPA2 these days and that's a lot harder to crack.
John has noticed that there isn't spell check in Android for Gmail anymore. Leo is surprised by that, but he uses Inbox instead of Gmail and that has it. Why would Google turn off spell check in gmail? Leo says it's a setting that got turned off. John should look in his settings.
Claire had a Yahoo email account and forgot to reset her recovery phone number, so she's now locked out of her account. Leo says that she can try and log into the general Yahoo.com. If that works, then she should be able to go into her account and change the phone number.
