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'm not entirely sure what you're asking. The site is just webpages - pretty regular HTML - so I would assume that it's as accessible to Android and iOS devices equally well, although I have neither to test. I believe that plain HTML provides the maximum accessibility for different devices.
As you will see on the site, there is both the web page, the RSS and Atom feeds for summaries, and a 'full text of the last 5 days' RSS feed. Additionally, there's a Google Currents published version of the content at http://www.google.com/producer/editions/CAowva34Bg/gerphs_risc_os_r... if you prefer that to RSS feeds.
I have a Kindle version of the rambles, but I shaln't be publishing it until the complete rambles have been published on the site. A Kindle document would fix the version, and I would prefer to have edited everything before it is published in such a way.
