Joey wants to know if Linux has a built-in VPN. Leo says no. He will need a provider to handle VPNs, not just software. Leo recommends visiting the Wiki for ARCH, a version of Linux. There's a great list of clients, carriers and servers that will run on Linux. That's the best place to start. Where can he get apps to download for Linux? Leo says that PopOS has its own "store," called the PopShop, which is an app that will help to install software.
Microsoft may be so anxious to get numbers up in its Windows app store that they aren't policing it. At least that's the story from How-ToGeek.com, which says that Microsoft doesn't care about app security. If you search for VideoLan's app, for instance, you get dozens of copycats which sell "help" to download the free app. It's a total scam! There's an app for the iTunes Player app for $9 that offers to help users download that free app as well.
