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.

Having 2 millions euros or more invested, some people working on it full time, supposed benefits from the ukernel architechture, but still so retarded (anew fpu support, no port while less tie to x86) I don't really get it. Minix started before Linux, was commercially supported (through the book purchase) and not just a puppy project from a student, but from a professor with more insight on the subject, considering how many books Andrew wrote.

Comparing Minix 3.2.1 to Linux 3.9... nothing to fell badly concerned though

Linux has lucky to have a few companies putting money on it as a way to get a free UNIX compatible OS, without having to pay lots of money for a commercial implementation.

Minix at the time was just a research OS, and suffered from the micro-kernel stigma thanks to the Mach failure. Many in the industry thought it was not worth as OS architecture.

Fast forward to 2013 and you have Symbian and QNX as successful micro-kernel OS, Darwin and Windows using hybrid kernels, OSs running on top of micro-hypervisors
and the public in general having more awareness in high availability and security issues.

That is the main reason why Minix got the EU funding and now some companies are looking into it.

Nope, Minix was close licensed when it was the right time to unleash the beast. Linux was free and "copyleft". I am, deep inside me, for the ukernel trend, but Andrew was unaware of the future where x86 rules them all. Linux was on the rights tracks from the beginning :

1- Open source
2- copyleft
3- x86
4- his original coder spending time maintening and evoluting

Minix was just the opposite, Andrew admitting it was just a professor project, yet with higher goals (portability, stability, security through the use of the ukernel architecture).

Sadly, the ACK toolchain is a mess to use, Minix is hard to maintain and doesn't run well on most VM, thus so few people gets invested into, and that sadden me. Inherently, Minix IS superior, but stalled for so long.

Nowadays Linux is everywhere Minix were supposed to be. Was ever Minix ported to the "64M SPARCstation-5" after all ?

No, the EU invested in Minix because it is a basic research project. Most of that money goes to finance infrastructure and grad student/researcher salaries in the institutions involved.

Also if by "mach stigma" you mean it being one of the most influential software research projects in the last 3 decades, then yeah.
