What about just not allowing passwords to connect from a network? Is it too simple, or what?

It's simply stupid to prohibit robots from connecting. It means you'll never be able to automate your work. It's also not viable to lock the system, as it'll turn any bot anywhere into a severe DoS attak. And trying to discern intent from behaviour is way too hard a task for a computer.

You can't change the referential during calculations. Not on Classical Mechanics, because referentials can not accelerate, and in general relativity things are much more complex. Thus, no, it does not take the same amount of energy to accelerate from 0 to 10mph as it does from 90 to 100mph.

The problem is worse than that. It's a matter of the media missrepresenting the problem, and people not looking into the details to notice the hype.

I've never seen a technical forecast being delayed, only anticipated. The first one I saw from the working group was working with widespread adoption (like what we have now) of IPv6 by 2020-2025 and IPv4 addresses running out by as late as 2030. The media can't stand having that much time to fix a problem.

Which won't be for a long while because of all the old computers out there that have either no or insufficient IPv6 support.

Just how old are you estimating those old computers are? Windows XP has support for IPv6, as do the first 2.6 Linux kernel. I doubt there's a single smartphone without support for it.

The only reason we are not using IPv6 all along is because ISPs decided to save some 5% (probably less) of the cost on their last upgrades, or because they actively don't want to supply it.

To be fair my (badly constructed?) printer loses precision from vibration much before the stepers have any problem.

Also, all steps that it missed were due to electronic or software problems. Except when the software sent things beyhond the end of the printer, it never lost a step due to physical resistence.

In a Linux computer the button continues there, but there is a warning bellow it telling that the campaign only applies to Windows computers. When I click the button, it tries to download .exe file, Igot tempted to run it on Wine and see what it does, but setting a VM and etc is too much work :)

There is probably something in the .exe to tell them if you switch back. But I doubt they reclaim the credit, as that would break consumer laws.
