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.

I just re-read my comment and I see it makes me sound like a bit of a jerk. Way to go, Justin, if he's just publishing HTML then. I am repeatedly annoyed by content that gets wrapped up into an app or some nonsense that makes it hard to read and share.

And the subject matter is interesting too, so I'll be excited to read it. Anything but boring-old-x86 is interesting stuff.
