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.

In the USA, and 28.

The issue with n=1s is that they can always be contradicted. For example, I'm almost the opposite of you.

I'm male. I'm 5'9" and weigh 118-120 lbs. I eat mostly bread and vegetables, rice, potatoes, with some meat and fruit. I can't stand most fat (most fatty acids taste like something rotting to me) and so I tend to have a very low fat intake. HCLF, effectively. I tend not to feel hunger much, so I use alarms to remind me when to eat. I'm active, I have stamina, and my biggest problem is keeping away from being dangerously underweight. When I diet I generally increase the meat/eggs/dairy amounts I eat in an attempt to gain some weight because I've gotten too thin. If I ate "as much as I feel like eating" I'd probably be grossly malnourished.

Different things work for different people. While it's true that no one can escape thermodynamics (if you eat less than you use, you'll lose weight) it's also true that if a diet is uncomfortable people won't stay with it. There's also the issue of bioavailability of the energy, the number of calories you actually get from a serving of food can't be more than what is measured by a calorimeter but it can be less.

It was listed as being a parody account several days before the raid.

Milk and cereal can spontaneously combust in this world too, if you enjoy the rich taste of potassium flakes.

I just moved, got comcast, hooked up my modem & router (brought my own, but reset to factory defaults before install) and got ipv6 out of the box. No mucking about needed.
