Linux After ten weeks of development Linus Torvalds has announced the release of Linux kernel 3.9. The latest version of the kernel now has a device mapper target which allows a user to setup an SSD as a cache for hard disks to boost disk performance under load. There's also kernel support for multiple processes waiting for requests on the same port, a feature which will allow it to distribute server work better across multiple CPU cores. KVM virtualisation is now available on ARM processors and RAID 5 and 6 support has been added to Btrfs's existing RAID 0 and 1 handling. Linux 3.9 also has a number of new and improved drivers which means the kernel now supports the graphics cores in AMD's next generation of APUs and also works with the high-speed 802.11ac Wi-Fi chips which will likely appear in Intel's next mobile platform. Read more about new features in What's new in Linux 3.9.

Hmmm, wondering if everything cut down as services, micro-kernel style, would run better and/or more securely.

Andrew, any input on the subject ?

What do you mean by "better"?

Micro-kernel is mostly run-time distinction; you can write a kernel with well defined modules that have defined interfaces for communication, but if they run in the same address space and thus gain efficiency they are will be less secure, but if the modules have their own address spaces and use message passing they gain security but lose efficiency. Linux decided a long time ago to share a kernel address space.

I know that :

http://en.wikipedia.org/wiki/Tanenbaum–Torvalds_debate

The result is here, compare with the EU funded Minix3 OS :

http://www.minix3.org/

Now which one is the most usable ? Which is the most portable ? FPU support was added to Minix3 through a Google Summer of code, have no extension support (MMX, SSE, ...) and do not run on ARM.

Linux, on the other hand...
