Europe Funds Secure Operating System Research
narramissic writes "A Dutch university has received a $3.3 million grant from the European Research Council to fund 5 more years of work on a Unix-type operating system, called Minix, that aims to be more reliable and secure than either Linux or Windows. The latest grant will enable the three researchers and two programmers on the project to further their research into a making Minix capable of fixing itself when a bug is detected, said Andrew S. Tanenbaum, a computer science professor at Vrije Universiteit. 'It irritates me to no end when software doesn't work,' Tanenbaum said. 'Having to reboot your computer is just a pain. The question is, can you make a system that actually works very well?'"
.. they want their funding back.
Seriously , I thought minix had been put out to pasture years ago.
Also what are 5 people going to manage that entire corporations and thousands of OSS developers failed to do in the last few decades? Ok , one of them might be the next Alan Turing and surprise us all but I won't hold my breath.
Has anyone noticed how more and more stuff gets moved from the Linux kernel into user space these days; FUSE is a good example. History may record that, broadly speaking, Tanenbaum was corrent and Torvalds was not. Anyway, I assume you are saying that since Linux has been so much more successful than Minix, we must listen to Torvalds and ignore Tanenbaum? On that basis, we should listen to Gates and ignore Torvalds!
No, but dividing things into smaller pieces makes it easier to fix those pieces in isolation. It's easier for a microkernel system to be self-healing because of that isolation.
This is not an amazing revelation. We've known about the idea of isolating changes since the invention of the sub-routine. The reason microkernels have always been relegated to second-best is that they require more context switching than a regular monolithic kernel. The tradeoff between "fast enough" and "reliable enough" has for some time now favoured "fast enough".
But that's changing -- people's computers are getting plenty fast. The 10-15% slowdown Tanenbaum claims for Minix3 is less of a drag than, say, an anti-virus program and could serve to more effectively prevent viruses into the bargain.
People who say microkernels are passe forget our industry is not set in stone. Priorities change and technologies change with them. In the last 10 years performance has become progressively less important than reducing bugs or speed of development. Microkernels have lots to offer in such a world.
Classical Liberalism: All your base are belong to you.
That's a rather ignorant viewpoint.
Tanenbaum argued for greater modularity and really that's no bad thing, his arguments were pretty solid theoretically. But as we all know, just as the most beautiful, maintainable, stable software designs are sacrificed in business for something that works now even if it has it's flaws, Linux was available, easy to use and just worked the way people wanted, that didn't mean it was inherently better in theory or that Tanenbaum is wrong anymore than it means Windows is a vastly superior OS to Linux and MacOS X simply because it has such a massively larger user base.
Basing your view on Tanenbaum's one comment towards Torvalds is also rather ignorant, throughout the discussion you're referring to, Tanenbaum was well composed and formed coherent arguments, whilst Torvalds at times acted like your average troll.
You see, the very fact Windows is far and away the most popular OS followed by MacOS X followed by Linux is evidence enough that popularity means nothing in terms of the actual quality of an OS, it merely shows which played the business game better.
Tanenbaum is worth listening to, his ideas and justifications included in that 17 year old discussion you mention aren't wrong even if his predictions on the future of computing were. This is a man who understands the theory of how to make a better OS more so than most people do, and yes possibly even more so than Torvalds. The problem is that he's a theoretical guy, so whilst his proposals may be better, they may not be practical at the time they're announced or he simply may not have the time to dedicate to proving their practicality. If they're not practical at the time he proposes them though that doesn't mean they'll never be practical as changes in computing architecture or even raw computing power may make them practical.
Hopefully he'll put this funding to good use and it'll help provide him the time and resources he needs to take his ideas beyond mere theory and he'll be able to backup his theories with actual working demonstrations rather than just arguments now. You can be a Torvalds fanboy all you want but Tanenbaum and Torvalds are two different people - Tanenbaum is someone who comes up with theoretical new concepts, Torvalds is someone who takes existing concepts and implements them well. Both have their strengths, but writing one or the other off is foolish when both have a lot to offer.
"Some researcher"!? The guy (prof. Tanenbaum) wrote the original Minix, which was the OS that inspired Linux and hosted the early stage of its development. Also see: http://en.wikipedia.org/wiki/Tanenbaum-Torvalds_debate
