Let’s look at open source software using a real-world example. To me, the FreeDOS Project will always be the first example I look to, so I’ll use that. It should speak to the commitment of the open source software community that FreeDOS continues under active (if slow) development 15 years after it was conceived. How has FreeDOS held the interest of its users? Because FreeDOS embodies the important qualities that an open source project must possess in order for it to succeed.
