Thomas wants to host a Minecraft server for his friends. Is port forwarding secure? Port forwarding is where you tell the router to send traffic coming in from a specific port to a certain machine. This limits a little bit of the potential damage from opening up a server to the outside world, but it will ultimately depend on that Minecraft server to be secure. It's important that Thomas keeps his Minecraft server secure and up to date. If someone can figure out how to get around his network via the server, he could infect his network.
John takes music lessons on the internet to play the harmonica. The teacher uses Adobe's Meeting, but he has extreme latency issues. Leo says it could be hardware, but more likely it's the ISP's data flow rate with Adobe. It's causing a delay from Adobe to John and back. Leo suggests doing PingTest.net to see what the latency is. If it looks good, then the problem is with Adobe.
According to this article, offices in London's Brent Council have replaced their receptionists with a holographic one that can answer limited questions and interact with people. Leo says it sounds like a scene from a bad science fiction movie.
Johnny was in Hawaii and wanted to try and get bumped off the flight like he talked about last week. All they would offer was $300 and so he passed on it.

Blake is tired of the rising prices of DirecTV. What are her alternatives? Leo says that it's still probably cheaper than cable. Of Course, Blake could "cut the cable" altogether and stream everything. But live broadcasts would still be an issue.
Carl keeps hearing about Cryptocoin. Is it the modern day gold rush or a pyramid scheme? Leo says that it remains to be seen. Value is reliant on the full faith and credit of the US government. All currency is based on that faith. But Toshi Nakamoto created BitCoin, which is a digital currency. There's no government backing it. The benefit, though, is that it's anonymous. But it can also be stolen just as easily, and there is no central bank or authority. If governments start banning it, like China has, it could doom the concept and make BitCoin worthless.
This quiz from the New York Times asks 25 questions about your personal dialect, and it displays a heat map that can very accurately pinpoint where you're from.
Jim changed ISPs and outlook now gives him a message saying the server doesn't support the encryption chosen (SSL/TLS). It only happens about 10-20% of the time. Leo says that's an odd thing. It could be security software that's running against it. Jim should try disabling his security software to see if it works. If it does, then the antivirus software is causing the issue and using a different antivirus may be the solution.
Rick entered a date on his calendar on the iPhone via FantastiCal, and his friend noticed that it appears on his calendar as well. Leo says it will do that if he had set it up that way. The calendar will see that he's put a name in the event and email it as an invitation. It's a nice feature, but scary if he doesn't see it coming.
Leo is flying to Las Vegas today. Not to attend CES, but to attend New Media Expo, which he's giving the keynote for. He's not staying for CES because he's now of the mind that it's just crazy to go and deal with the hundreds of thousands of people. He can learn just as much about what's going to be there through the internet.
