Can you point me to recent developments in operating systems?

I开发者_StackOverflow社区t has been a full 19 years since I studied operating systems and need am looking for a list of recent developments. So any thing since Virtual Memory, paging, all of the good stuff.

I would prefer a book so I can get everything in one place. I'll pick up 'Understanding the Linux Kernel' from O'reilly to get started.

I'd say language-based/managed operating systems are somewhat recent and interesting, they rely on compiler/linker to enforce policies instead of runtime hardware-checks (so that, for example, all kernel code and user code run in the same process)

Do you mean developments or trends? Much of what is seen today is just repackaging or re-labeling of old ideas. Linux can trace its roots to a large multi-processor mainframe of the late 1960's.
