RISC OS The lead developer of a niche ARM-powered OS has written a string of in-depth articles on the design, implementation and testing of a commercial operating system. Justin Fletcher was the architect of versions of 4 and 6 of RISC OS, the ARM processor's original operating system. Although his pieces will be best appreciated by RISC OS and Acorn users old and new, the series is a fantastic insight into operating system design: check out his build system for compiling code into ROM images, the abstraction of video graphics from a legacy 1980s-era kernel, converting images on the fly, testing and debugging, executing applications and plenty more. Justin has written tens of thousands of words and will be publishing new pieces daily online and in Android and iOS-friendly formats.

They could have easily become the kings of the professional operating systems that are both legendary, fast, well-thought and extensible ... BUT ... they're not open source, and this will make their life miserable at best. At worse they can just dissapear, like BeOS. Then we will get some rewrite of the RISCOS code after several years of unnessesarily doubled work.

Come on people, wake up. Open source your stuff. It's not 1980s. The model has changed. Open source works and closed source doesn't work. And that won't change, because if you get a taste of the freedom once, you won't give it away anymore.
You can be either loved by the small group of enthusiasts with big wallets, or by the huge group of enthusiasts willing to pay for support and help. Don't be a prick, for f#@#$'s sake.
