You don't have to be a genius to get 10 kids. In fact, being a genius usually leaves you too preoccupied with too many other interesting things so you don't constantly want to make babies.
Microkernels are only better in theory if your theory doesn't include performance. For example, the old Minix-1 filesystem was run by a single task. This means that if this task was waiting for a response from the floppy disk it could not serve requests from other user tasks which needed access to the faster hard drive. This problem was too easily dismissed by Tanenbaum. Microkernel advocates claim that performance is just a small problem that can be fixed by special purpose hardware, but the floppy example shows this to be incorrect. Trying to design a microkernel filesystem layer that doesn't have these performance issues is more complex than just writing a monolithic kernel.
I agree. Take this part, for example:
Network access may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. A company could exploit this by claiming that any unauthorized modification might potentially violate the rules and protocols for communication. Because it has no way to tell in advance, it could create a mechanism where any unsigned binary shuts down the network as a precaution. For example, in the case of networked gaming platforms where cheaters can ruin the experience for the rest of the community, such a precaution may be considered reasonable.
Or this part:
"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. What if the 'procedure' to install modified versions includes passing the vendor's Quality Assurance program ? This seems a reasonable requirement, because it's the exact same thing that the vendor does for its own software versions. A vendor may even offer to validate 3rd party changes for an industry-standard fee (which would of course, be totally unaffordable for the average hacker)
Applications sometimes need to know whether a file is a symbolic link or not. For example, an archive utility (e.g. tar) may want to archive the symbolic link rather than the file it points to. Programs that delete files may sometimes want to delete the symlink, and sometimes the actual file. Same applies to changing the name/ownership or access rights. Applications that do recursive traversals of a file tree (e.g. find) may want to stop at a symbolic link to a directory in order to avoid infinite recursion.
Unfortunately, this is not a sustainable model for a large population. Imagine a country in which everybody tried to be a reseller of imported items or outsourced work. Where would the money come from to import these items/labour in the first place ? In the long term, the amount of imports must balance the amount of exports. A temporary imbalance can be supported, but at some point in time, a correction is unavoidable.
A chip technology that will be available within five years, code-named Vanderpool, will allow users to partition the processor inside their computers. In a demonstration, Otellini used a PC to beam an episode of "The Simpsons" to a plasma TV, while another Intel executive booted and rebooted a game with the same machine.
This is because gold is, effectively, useless, and only holds stature for traditional and rarity reasons (i.e. 'lots of gold makes me look good because there's so little of it available'). If they brought back significant amounts of oil, however, things would be quite different, as oil has a non-cosmetic use.
Actually, gold is a very useful material. Check out this link for some uses. It doesn't corrode, it is an excellent conductor of heat and electricity, and can be made into really thin wires without breaking. An abundant supply of the stuff would probably help to find more uses for which it is currently too expensive.
However, if a user has built up Google karma, and Google recognises this user by a cookie, then the bot could simply locate the user's cookie, and use it to fake its credentials. Even a password wouldn't be safe if the bot uses a keyboard logger.
How would you defend against somebody releasing a worm that infects thousands of machines on the net, in order to create a army of "moderation zombies" that can be used on certain pages ?
Actually, 100W is equivalent to about 2000 kcal/day. It would be a fairly big deal, but not beyond what a fit person could handle (at least while you're awake). I imagine it would be hardly noticable for an elephant.

Ghostview/Ghostscript has no problem doing this, and can also write the document back to disk without any such protection. This can also be used to 'fix' documents that you can view but not print.
Additionally HP-UX, Linux, Solaris and recent releases of FreeBSD cycle back to zero after 497 days, exactly as if the machine had been rebooted at that precise point. Thus it is not possible to see a HP-UX, Linux or Solaris system with an uptime measurement above 497 days.
The winds, even though the atmospheric pressure is low, are still capable of moving sand. Over a couple of million years, this may well change a planet's geology. Go take a look a the grand canyon to witness the effect of time.
When they're talking about the intense radiation from the sun, they're not worried about the survival of the drill or lander. They're talking about the the radiation destroying evidence of life on the surface, and that's why they need to drill. Since the atmosphere is so thin, you can expect a heavy dose of radiation at the surface. There are worse things than UV, such as high energy cosmic rays, which are mostly blocked by earth's atmosphere, but can penetrate a lot further on Mars.
The point is that XS4ALL doesn't want to block e-mail themselves. They don't want to filter or censor anything. Instead they want the originating company to stop sending the e-mail through their networks in the first place. That is what the case was about, and the judge ruled in their favour.
Very true. Also, they have a very interesting policy that they encourage you to crack their systems, and as long as you don't destroy anything, and tell them about the security hole you've found, they'll refund part of your subscription as a reward.
Combine this with the fact that in the developed nations it is no longer difficult to raise a child to child bearing age. Thus a successful evolutionary strategy is to have a minimal number of childen and invest heavily in them. Which is what we are seeing today.
This makes no sense. I agree with you that there's a balance between having a lot of children, and having to share your resource between them, or having a few ones, and raise them really well.
However, the easier survival becomes, the more the balance should shift towards having more children, not the opposite way.
Even somebody with a low-income job can still have 6 kids, and have a good shot at raising them all to adult age without any of them dying. Now, maybe you think your single child that you've raised to be a nobel prize winner is more successful. From a evolutionary standpoint your genes just lost 6 to 1.
Why isn't every woman in a developed country walking around with 20 kids?
Because evolution takes time, and hasn't caught up with the changes in our society. Plenty of people chose not to have children, or not very many because they have other interests, such as their career. Other people don't have a career, and they don't consider the cost of sending their kids to a university, so they'll have more. Eventually, the second group will outgrow the first (assuming society isn't going to change dramatically while this is happening, which is not very likely, I admit).

If you need something printed, which most products do, it doesn't cost anything to add a barcode.

Ah, that's why I can never find music or art on sites like youtube.
If we ever hit the 'Mad Max' stage, regular books like Twilight will be especially useful...as toilet paper and for starting fires.
You mean, regular books will be useful as kindling ?

It doesn't really make sense to use flash for swap space. Instead, just add more RAM which has a higher speed, and higher density per device.
I'm sure airlines would provide refueling services in-flight.
Why ? They already provide low-voltage outlets to power laptops, why not add more of those ?
It would be much more convenient to be able to instantly fill a battery with methanol rather than having to wait hours for it to charge
Since you're sitting in the plane for hours anyway, constrained to a seat, this isn't such a big deal.

Downside: paintballs can't acheive the muzzle velocity bullets can, and therefore don't have nearly the range.

I'm not sure that's really a disadvantage, though
