And the moment you make any sort of mistake or have a charge you can't pay off in full (regardless of your level of discipline, this will probably happen eventually) the credit card company will earn back every cent you've made from your cash back or rewards. In fact, they'll likely earn it back and many times more. This is the business model behind rewards programs. Sign the customer, make them believe that living month to month on credit is okay, then wait for them to fuck up.

It's gambling, and the bet is that you'll never ever ever ever ever run into trouble paying off your bill.

Do You Really Need a Smart Phone? 851

Roblimo writes "My phone is as stupid as a phone can be, but you can drop it or get it wet and it will still work. My cellular cost per month is about $4, on average. I've had a cellular phone longer than most people, and I assure you that a smart phone would not improve my life one bit. You, too, might find that you are just as happy with a stupid phone as with a smart one. If nothing else, you'll save money by dumbing down your phone." I stuck with a dumb phone for a long time, but I admit to loving the versatility of my Android phone, for all its imperfections.

New Kind of Metal Theorized To Be In the Earth's Lower Mantle 117

slew writes "This article talks about a study accepted to Physical Review Letters which theorizes that iron oxide goes through an insulator/metal phase change with high temperature and pressure. Originally it was thought to be a crystalline structure change, but now apparently it is theorized to be a new type of metallic state. This discovery might offer new insight on how the earth's magnetic field operates."

Cool. You teach your own kids. If your neighbors choose not to they'll be too stupid to do what you want most, which is to leave you alone.

Libertarianism breaks down as soon as you interact with other people. Like you're doing right now. On the Internet. Which was invented and paid for by the United States government.

Scientists Build Wireless Bicycle Brakes 213

itwbennett writes "Computer scientists at a German university have built a set of brakes controlled using a small motor for a braking mechanism and a wireless signaling device to tell it when to brake and how hard. 'Making a popular set of bike brakes wasn't really the point of the project,' says blogger Kevin Fogarty. 'The project was to find out how to make the wireless connections between two components of a system that has to operate in real time – with milliseconds of difference between success and failure (PDF) – more reliable than systems that are normally connected by a wire.'"
