Comment Re:Tannenbaum's predictions... (Score 1) 136

Predicting that x86 would go away was more wishful thinking than anything else. At the time, Intel had just switched from pushing the i960 to pushing the i860 and would later push Itanium as x86 replacements (their first attempt at producing a CPU that it was impossible to efficiently compile code for, the iAPX432, had already died). Given that Intel was on its second attempt to kill x86 (the 432 largely predated anyone caring seriously about x86), it wasn't hard to imagine that it would go away soon...

I found Modern Operating Systems better than the Minix book. The Minix book tells you exactly how a toy OS works in detail. Kirk McKusick's Design and Implementation of the FreeBSD OS (new version due out in a month or two) tells you how a real modern OS works in detail. Modern Operating Systems gives you a high-level overview of how modern operating systems work and how they should work. If you want to learn about operating systems, I'd recommend reading the FreeBSD D&I book and Tanenbaum's Modern Operating Systems and skipping the Minix book (which was also a bit too heavy on code listings for my tastes).

I feel it necessary to point out, though, that OS X is not a microkernel system comparable to Minix

While this is true, it's worth noting that a lot of the compartmentalisation and sandboxing ideas that most of the userland programs on OS X employ (either directly or via standard APIs) have roots in microkernel research. OS X is in the somewhat odd situation of having userspace processes that are a lot more like multiserver microkernels than its kernel...

There is nothing natural about a free market capitalist society allowing itself to be transformed from a society with more equitable distribution of capital into a society where very few people control most of the wealth and people are not really free to exchange goods, services and capital.

This is happening as the result of government regulations and because of public policies and not simply some sort of passive "deregulation" where the government steps back and does nothing. The government isn't deregulating. We have as much regulation as ever, it is just violently skewed towards protecting the vast and unbridled wealth of the rich while not diligently making sure that those without wealth have a level playing field in a free market.

If people continue to breed as they currently do, we're going to be just fine.

That would be true only if current population levels are actually sustainable over a longer term and depends on what your definition of "just fine" is. The evidence so far is mixed. Yes, we have apparently been able to feed almost everyone and there is some additional arable land that could be put into production, but not too much more land, especially given the pressures of development for housing, industry and transportation. And we have seen some pretty massive wars and genocides in the last hundred years which are at least partly the result of temporary or perceived resource scarcity. Japan wanted to control its oil supply in World War II and Germany wanted to directly control its oil, coal and food supplies. Other wars have been about oil. The Rwandan Genocide certainly had a component that was caused by resource scarcity.

So far with a human population in the billions "just fine" has meant periodic wars and genocides which kill millions and millions of people.

I don't think "just fine" means what you think it means and we would be really much better off if we had worldwide birthrates somewhat below replacement population. When it comes to population and natural resource utilization you never want to think about getting anywhere close to 100% capacity. You should always aim for excess production capacity to account for natural disasters and wars.

Apparently the early script drafts had a more plausible explanation: that the spare brain capacity of humans in a dream-like state was used as processing power to run the AIs. One of the editors thought this was too complicated for a movie-going audience to understand and so replaced it with a magic perpetual motion machine.
