Apps, Operating Systems (Windows, MacOS, Linux), or pro level software.
Ron has noticed that some of his programs autostart when he boots up. How can he stop that? Leo says he doesn't like apps running in the background. There is a way to stop it, though. There's a power tool from Microsoft called Autoruns that will enables him to turn that stuff off. It's a part of their SysInternals Suite.
Google's latest artificial intelligence, AlphaGo Zero, now has the ability to teach itself how to master board games after only knowing the rules, and without any human intervention. While previous AI took months to beat the world champion Go player, this latest system was able to master these games in less than a day.
Philip keeps getting messages that his OneDrive is full on Windows 10. Leo says that OneDrive is built into Windows 10 and it syncs his data to it online. He can't really remove it, but he can disable it. This article at support.microsoft.com explains how to do that.
Lance bought a new Dell XPS 15 with a 4K screen for Christmas and he wants to know how to move his data and apps over to it from his old one. Leo says he isn't a fan of the transfer wizards because they usually bring over stuff that causes problems. So Leo recommends installing all of his apps separately. Backing up Outlook is fairly easy. Outlook stores everything in a file called Outlook.PST. So he can save that and then move it over once he's reinstalled Outlook on his new laptops. Or he can archive and install.
Diana just bought a second tablet. How can she sync her games on both so she can play them? Leo says that's a feature of the game itself, not the OS or the tablet. She may have the ability through Google Play Games, but the app must support it.
Charles bought a new computer and is trying to back up his operating system before he gets going. Leo says it's a good idea to make an image right at the beginning. He can even do it on a small 8GB USB thumb drive and keep it in his pocket. The laptop will likely have a rescue utility that will enable him to create a restore rescue disc, but he can also use the Windows 10 backup feature. Just press Windows Key and type "Backup" and then go to backup settings. Then click "Backup and Restore (Windows 7)." This is actually an image backup, and it will create a system image.
Michael is trying to shuffle his playlist using RhythmBox, but it keeps playing artists back to back. Leo says that if the playlist is small enough, it could end up doing that, but if it's a large enough list, it is more likely an error in its random number generator. It's open source so it's probably just faulty code. Amazon Play seems to do the same thing, though. Unfortunately, there's no real fix for it other than filing a bug report and waiting for a fix.
Trent is a video teacher and he wants to do live Chroma Key with green screen with his kids. How can he do that more affordably? Leo says that lighting is everything. He'll want to be sure the lighting is smooth and even, and doesn't cast a shadow on his green screen. Then he can use software like ManyCam. It works great, according to the chatroom. Wirecast is another option, and it is 30% off for Black Friday.
When Chris searches for something, he wants to be able to just use the arrow keys to select results, but it won't let him do that. Leo says that's the CSS. He can provide his own style sheet that would include this if he wants, but in order to do that he'd have to learn the syntax of CSS. If he searches for this problem and "CSS," there's probably somebody who has written his or her own style sheet. Then he can just download that and change the settings to use his instead. This could be helpful to someone who can't use a mouse.
