OSNews, Generic OSes Torvalds has indeed chimed in on the micro vs. monolithic kernel debate. Going all 1992, he says: "The whole 'microkernels are simpler' argument is just bull, and it is clearly shown to be bull by the fact that whenever you compare the speed of development of a microkernel and a traditional kernel, the traditional kernel wins. The whole argument that microkernels are somehow 'more secure' or 'more stable' is also total crap. The fact that each individual piece is simple and secure does not make the aggregate either simple or secure. And the argument that you can 'just reload' a failed service and not take the whole system down is equally flawed." My take: While I am not qualified to reply to Linus, there is one thing I want to say: just because it is difficult to program, does not make it the worse design.

Linus should know better

The whole 'microkernels are simpler' argument is just bull, and it is clearly shown to be bull by the fact that whenever you compare the speed of development of a microkernel and a traditional kernel, the traditional kernel wins.

I'm a bit disappointed to see that kind of disingenuous comment from someone like Linus Torvalds. As a BeOS user, I'd probably be a hypocrite if I took a firm stance on either side of the micro/monlithic argument - but I don't see why Torvalds would assume that "simpler" would automatically mean "less development time." In many cases, simple is much harder than complex - it seems counter-intuitive, unless you have experience trying to simplify something that's inherently complex.

There's a well-known anecdote among journalists, about the rookie writer who submits an article by dropping a half-foot stack of paper on his editor's desk and saying "I would have made it shorter, but I didn't have the time."
