But why linux won? We know now it won, but what is the reason. Tanenbaum was theoraticaly correct. İf HN exist back then, I would argue most devs here would say Minix will last longer, monolithics is indeed an old idea that had been tried and tested etc.

  İs performance really the only key factor when it comes to software design ?

It seems to me that the microkernel idea came from observing that virtual memory protection made life easier and then saying “what would life be like if we applied virtual memory protection to as much of the kernel as we can”. Interestingly, the original email thread shows that they even tried doing microkernels without virtual memory protection in the name of portability, even though there was no real benefit to the idea without virtual memory protection, as you end up with everything being able to write to each other’s memory anyway such that there is no point,

  Same question for the iphone. There are some link from HN where people saying iphone is dead bcs it does not support flash. But it didnt. Why it didnt?
