Also the Banach-Tarski paradox.

I have an algorithm. I open Keepass, type my master password, and use the generator to make a password for that site!

Freyja is also a goddess of War and Death. She takes half the slain warriors, Odin takes the other half.

So people have a "right to be forgotten" except by people actually publishing information about them. If the public record is important enough to preserve in violation of this "right" then telling people how to access the public record is surely an important duty.

The site owner should be responsible, not the search engines who don't host the content.

The problem is that you can't hide things from the service provider with nothing but a browser. You need an addon or such to do secure crypto. You need to decrypt the password database locally, in-browser, and without an addon that means using JS crypto, which isn't ideal. Your mailing example is very different, since it doesn't matter if the service provider knows the address and financials, they're the intended recipient of the info! With a password manager, you don't want the service to be able to learn the contents of the encrypted database. That means the encryption/decryption must be done client-side.

That said, it's perfectly possible to store the encrypted database on the internet. A local encryption/decryption program (like Keepass) works just fine, and if combined with a cloud storage client that also does local encryption/decryption (Wuala, Spideroak, etc) it should be quite secure.

I step off my bike, hit the walk button, and wait for the walk signal. Then I walk the bike across the crosswalk and get back on. It's really easy to become a pedestrian with a bike, and therefore be subject to the laws governing pedestrians. Just get off the bike!

Jetpacks are possible, but probably will never be practical.
The issue is the energy density of the fuel. If the energy density is low it takes a lot of fuel, which reduces flight time. If the energy density is high, it's a bomb strapped to someone's back, which means adding safety features, which add weight, which reduces flight time.
Jetpacks have been made, and they do work, but only for short times. You'll never fly around in one like a helicopter, the chemistry simply doesn't support it.
Sadly, Robbie Rocketpants shall forever be a part of the diseased imaginations of utter smegheads.

Helicopters fly because they're so ugly the Earth pushes them away.

Well, it's certainly better than timothy...

Why, you're perfectly correct! The arrangement of the atoms doesn't matter one bit, just the constituent elements. Hydrogen Cyanide (HCN) is perfectly safe to eat!
Oh wait no it isn't. Even though it's just hydrogen, carbon, and nitrogen.

Failure to account for cheating and lying by anyone who can get away with it is a fundamental failure. Any theory of economics that assumes things dramatically at odds with reality (eg rational actors, perfect information, fair behavior, etc) is utterly useless when applied to reality. A bit like how the classical physics example of a spherical cow in a vacuum is really, really bad at modeling the movement of livestock. Thankfully physics has gotten rather far beyond such toy models, hopefully economics will get there too.

I hate the feeling of a watch on my wrist. I'm not sure why, but I never liked it. When I was a kid before cell phones became common I discovered that, and quickly became the only kid in high school with a pocket watch. And a pocket smart watch is just a cell phone. Possibly with a lanyard, though my current phone (SGS4) sadly lacks a way to attach one.

Naw, just a typical Twitter user.

At the same time, any sufficiently advanced malice is indistinguishable from incompetence.
