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.

"I suggest the author read Minsky's early work. "signal-based" programming is the Nth in an infinite series of attempts to model the asynchronous processes that make up software as if they were synchronous. It is doomed to the same failure of all such attempts."

This makes no sense, IMO. Synchronous, signal-based applications abound. There are spiking (pulsed) neural networks, spreadsheet cells, etc... all over the place and they work perfectly.

That there are some problems that can be modeled synchronously does not imply that all problems are effectively modeled this way.
