Nathan is 10 and he's interested in Linux. Would it be a good idea to switch to Linux? He's tired of Windows. Leo says switching would be an interesting thing for Nathan to do because he'll learn about Unix-based operating systems, which is the basis of most networks. Most servers run on Linux. If Nathan wants to grow up and get a job in computing, having an understanding of how Linux works would be most beneficial. Another thing that Nathan can do is get a raspberry pi computer for $35 and build his own. It comes with Linux and that way he can have both.
Barry uses a Chromebook to transfer his images to an external hard drive, but now he can't open it in Windows. Leo says that issue may be that the Chromebook formatted the hard drive in a format that Windows doesn't recognize. It's likely formatted in a Linux format, like EXT 2 or 3. Barry can get an extension to Windows that will be able to translate it. Check out Ext2FsD.
Jay wants to know if removing viruses is the same between Mac and Windows. Leo says that there's a debate that Macs are either more secure, or are a smaller target because there are fewer of them. Leo says that malware writers are going to write for the largest segment of computers. But OS X is based on Unix and that's more secure than Windows. OS X also has an administrator requirement when installing software.
