Leo says that he's decided not to go to Cuba because of the political situation around the world. Johnny says that issue isn't really in Cuba, especially for media people. It's more the infrastructure. There isn't any Wi-Fi, and the hotels are old and very expensive.
Scott reports that NASA is going to do the first ever, live 4K stream from Space. They will be sending it to earth at 18MB/s which Scott says is really small. The backend is being handled by Amazon's Elemental streaming and cloud based processing division, which will stream it online via H.265 HEVC and then transcoded into H.264. So to watch it online, you'll need at least 45MBps of bandwidth.
Josh bought one of the last 17" MacBook Pros a few years back and he just got a message that Safari will not be supported by Google on it. Leo says that Google is starting to do that, and Apple isn't going to update it past Mountain Lion. So Leo recommends using Google Chrome. It'll be up to date. Chrome can also import all of his Safari bookmarks, too.
Christian wants to know the difference between a router and a modem. Leo says that they handle two different jobs but some people get a modem that also works as a router from their ISP. Modem means "modulate-demodulate," and in the early days, it would take the bits and turns them into sound and then back again over a telephone line. Now they send the data digitally. Then it converts it into RF signals and back to bits.
Johnny Jet wants to talk about the United Airlines fiasco and he says that there is a lot of misinformation going around about what happened. The Captain has the power to remove anyone from his plane, and that's how it should be. But Leo says that United made the mistake of bumping a passenger after they got on the plane and settled in. They should have done it before boarding. It was also not a United flight. It was Republic Airways, a subsidiary. In the end, it was bad customer relations and United is paying for it.
Ed would like to set up a delivery business where he can take orders online, but the ISPs where he lives are rather slow and unreliable. Leo advises looking into a business class account which offers a guarantee of good service. Leo also says he can get computers as his receivers and get a router that supports cellular bandwidth. That way he'll have a more reliable service with a cellular system.
Leo says that most browsers can enlarge the screen text to make it easier to read. In most browsers, pressing "Ctrl" and "+" will make the text bigger, while pressing "Ctrl" and "-" will make the text smaller.
As we get bigger screens, text seems to get smaller because a higher resolution means smaller dots. Richard can go into the Windows' Control Panel and change the resolution settings to make his display show everything larger. Windows 10 also has a slider that will make the fonts larger.
Kenny wants to know music streaming service is the best. Here are all of the options:
