Not siding with Keurig, but just out of curiosity, how would you to create a DRM scheme that can't be bypassed with this replay attack? Apparently [0] the DRM works by shining a light on an ink marking and registering the wavelength of the light reflected back. I figure one simple scheme would be to 'burn' the key after it is read. i.e. physically disable the DRM ink by heat/perforation/other ink, so that once used,…

I'll bite. Cut power to the heat source/declaw the perforator/plug up the ink jet. I have physical access, after all. Keurig is in the position that they can attach a number to each one of their coffee cups, and the machine will refuse to brew if the number doesn't prove the cup is authentic. If they give all the cups the same number, as they apparently have chosen here, than all anyone has to do is present that numb…

Instead of starting with each machine having the entire list of numbers, wouldn't it just be easier to read each number it encounters, store it and then check future numbers against the stored list? There are sooo many more numbers my machine will never see. Why keep them all stored in all machines? And if they are concerned about running out of numbers and repeating them, there could be a timestamp attached to each locally stored number and have them expire from the list after X months. The chances that a person would save a bunch of K-cup tops to use to bypass the DRM 6 months later is pretty slim.

I'd recommend anyone trying this to be cautious with the amount you add.

Primarily because caffeine is extremely bitter and adding too much will ruin it. I tried to put like 500mg of caffeine powder in my cereal once and it was utterly disgusting. I got about 4 spoonfuls in before I couldn't take it anymore.

why wouldn't you just take caffeine pills man

Call me paranoid but I refuse to drink hot liquids out of plastic containers of any kind. A glass french press is the way to go.

As someone who owns (and regularly uses) an aeropress, may I ask why? Simply out of of curiosity, not out of disagreement.

long story short, transparent plastic containers tend to imbue their contents with a chemical called bisphenol-a (aka bpa), which is a compound similar to estrogen which may impact human physiology in a wide array of ways[0], or chemicals that are structurally related that aren't well studied but could be similarly damaging[1]. this applies to all transparent plastics and isn't specific to aeropresses

Anyone who uses a Keurig needs to: 1) punch themselves in the nuts, 2) go plant a tree. If you drink it out of a styrofoam cup, plant 2 trees.

that is, if the person only uses disposable K-cups. this wouldn't apply to anyone using it to brew their own coffee without trashing a plastic cup every time.

Agree, nut punching not required for re-usable cups. I have yet to see someone actually use them, though, and I've seen a lot of Keurig machines.

For a single cup of coffee, I'm partial to the AeroPress. It takes a bit more work, but the strange looks I get from my coworkers is worth it.

Strangely, I heard somewhere recently that french press coffee has toxins in it that would normally be filtered out by the paper filter...

The Aeropress has been BPA free for years now.

I'll probably get downvoted but fuck it - I use disposable plastic K-cups every day, and I do it with gusto. Some days I use styrofoam cups, but most days I use my mug.
