Keurig 2.0 Genuine K-Cup Spoofing Vulnerability
An anonymous reader writes A security researcher has released a humorous vulnerability description for the Keurig 2.0 coffee maker, which includes DRM designed to only brew Keurig brand coffe pods (K-Cups): "Keurig 2.0 Coffee Maker contains a vulnerability in which the authenticity of coffee pods, known as K-Cups, uses weak verification methods, which are subject to a spoofing attack through re-use of a previously verified K-Cup." The vulnerability description even includes mitigating controls, such as keeping the Keurig in a locked cabinet when not in use.

Apparently, they are using a propietary ink: http://www.consumeraffairs.com... rather than RFID.
Here in Montreal some dude has a mushroom growing kit that grows on a bag filled with coffee grounds. They were the most intensely flavored mushrooms I ever tasted. I was like getting hit in the face by a boxing glove made of mushrooms.
Mostly random stuff.
Even worse, they might brew the coffee with (*gasp*) Dihydrogren Monoxide!!!
My sci-fi novel, Ghost Thief, is now available from Amazon.com.
High pH would be very alkaline. I guess you meant low pH, because it's a common myth that coffee grounds are very acidic. They are pretty near to neutral and actually get more basic as they decompose.
I just measured the pH of some coffee grounds here in my kitchen. The results ---> 6.9
Keurig K-Cups are for people who don't know how to make coffee. Where did their coffee come from and how old is it? Is it a blend or single origin? What roast is it, or is it a blend of different roasts? What's the grind? What is the temperature of the water in the machine?
I roast green coffee beans, let them rest for a day, grind the beans just right for whatever method I'm going to use to make the coffee (drip, espresso, French press), and brew with good filtered water at the right temperature for just the right amount of time. Even $tarbuck$ can't come close.
