More Simple, More Secure
This is a great reminder of not only the importance of integrating solid development practices no matter how mature your project is, but also that open source code (or "free" as in freedom) has benefits far beyond simply being free. With deep insight into kernel internals, for instance, the entire kernel hacking community have access to code, scanning results, and developer knowledge lending to important security and functional bug fixes.
However, it is also a lesson in bloat. More and more I'm building my kernel with a stripped down footprint, not only choosing Linux-libre over the mainline code that contains non-free "blobs" which could contain security issues that can't easily be fixed because they are closed source objects, but also longing for a more micro-kernel-like build. Kernel bloat has been the topic of many a paper and article and the simple truth is that simplicity lends to security in terms of manageable code.
That said, I have watched the development of Linux since the early days (I'm practically a gray-beard) and it is one of the most impressive projects out there, with lots of strong personalities but with a drive to make sure users continue to have a free kernel that give people what they need.
Great article for reminding everyone why we love Linux.
