I developed my first web app as part of my final project in college. Instead of developing a web app only for the purpose of completing my project, I chose to develop one that could solve a real-world problem. I decided to create Cyber Manager, an online cyber cafe management system for cyber cafe administrators, which has been downloaded nearly 3,000 times since I first uploaded it on SourceForge.net in 2011.

Open source is a developer-centric solutions model, which, in a nutshell, could be described as building communities of developers to solve problems.

Second, if they then make their solution available to other developers it can develop into a full blown thriving open source community. When it works it is a fantastic process to behold and it this simple model that has changed the history of computing. read more

How will we meet the needs of users at that scale? The answer is simple: collaborate or die. read more
