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.

Open source wouldn't have paid the bills, for me, and closed source barely did - closed source being a requirement of the license. There are those who have a great regard for open source, and honour the agreements that are in place. There are others who don't, and have to be put in their place. But whatever the ideologies, I still try to keep from being insulting to others that have a different viewpoint.

Sorry if that insults you. I admit I went a little bit too far. I'm kinda grumpy in the morning hours ;)

Anyway, I do think that FLOSS is the presence and the future, but I accept the ones that are willing to stay with the closed source model. It's their choice [with their profit or loss].

Best regards

Another lineage of RISC OS is moderately ~open: http://en.wikipedia.org/wiki/History_of_RISC_OS#Post-Acorn_developm... (even if apparently messy at times http://en.wikipedia.org/wiki/RISCOS_Ltd#License_dispute )

...which doesn't mean "the kings of the professional operating systems that are both legendary, fast, well-thought and extensible" - RISC OS just isn't that good, it seems.
