The "slight bulges" (your #4) fails for a similar reason - ships have to climb UP a bulge, which takes energy, so either they're going from higher to lower when they start (so no need for wind or rowers) or they're going from lower to higher (so the return doesn't need wind or rowers), so it fails based on simple obsedrvation - you aren't going "downhill" in either direction.
Actually the ocean does 'bulge' in certain places. From what I recall from oceanography, differences in the height of the ocean (WRT some fixed, imaginary reference) were once among the plausible theories of what drove the ocean currents. Measurements indicated that the difference across the Atlantic ocean was only about three meters, which was proven to be insufficient over such a distance to drive the currents.
she sees it as this obtuse, obnoxious affront to the status quo
So how did Apple increase its market share so much?
However it seems in practice the elimination process would fall foul of the law.
1. Open source the solution, claim 'for academic purposes only'.
2. Let someone else solve the problem for you.
4. No profit, but you made the world a better place.
e-mail would be unusable for people whose computers are part of botnets because everyone would block it as spam (which is not really an acceptable solution)
I respectfully disagree.
If users cannot learn to police and maintain their own computers, they should have their network resources restricted. When one of my flatmates botnetted his Windows PC, I got a message from our ISP stating that a computer on my network was a zombie and our service would be temporarily disconnected if the bot was not stopped from spewing trash. I filtered-out his MAC addy on the router until he was able to fix his machine (with my help). By forcing and helping users to learn more about their PCs, much of the current spam traffic could likely be reduced, since most of it comes from botnets.
I learned about computer security and maintenance the hard way, as I imagine many
Further some of us simply can't fit into the common compact car, that is certainly poor engineering because I'm only a hair over 6' tall, but highlights that one size doesn't fit all.
There are many compacts that aren't built for tall people, but I'm 6'5" and comfortably drive a Chevy Aveo. There are affordable, fuel-effecient vehicles out there for uncommonly large people.
