DRM Tinkering with Intel's PXA270?
putko asks: "Intel has a new line of chips with DRM built in. This appears to be the very first DRM-enabled chip to hit the streets. This microprocessor is unlike others available, because the user doesn't have complete control over the thing, and your computer can (theoretically) betray you.
For a while now, there have been computers (IBM ThinkPad) that won't boot unless you give the password, but you could always rip out the hard drive and read it, right? With this chip, the keys and RAM are on the chip, and the flash is encrypted, so this really looks locked up tight.
Has anyone worked with this chip, and is possible to build your own device that uses the Intel Trusted Wireless Platform to protect your secrets (like your software, perhaps)?"
"I'm reminded of this due to Slashdot's recent story on the iPAQ, which uses the chip (and has some neat security features too). Somewhat surprisingly, nobody brought up the Doomsday scenarios, there. It should also be mentioned that there are companies selling incredibly tiny boards for it. Maybe you can run Linux on them?
Wouldn't it suck if the chip had the capabilities and you couldn't use them in your own projects -- e.g. if that was just reserved to big companies like Microsoft? On the other hand, if you can use the features, you might see some neat applications. Assuming you can program the DRM stuff, how do you avoid locking yourself out of the chip while developing? What extra pitfalls may developers run into using it?"

Okay, first off, no one cooks toads. All toads are poisonous to some extent or another. It's their natural defense system (along with peeing on you when you pick them up.)
Some people do, however, cook *FROGS*. And when they do, they'll typically kill them and cook just the legs.
Now I've never tried tossing a live frog into a pot of cold or hot water, but I'd assume they'd jump out either way. The frogs I've tossed into puddles and ponds hop off immediately.
Oh, sorry... you were making some other point, weren't you? Nevermind then.

Better learn to read it, cuz soon you will be Uncle Joe's droog.
An ex-commie told me some wikked KGB stories... actually, now that I replay them in my head, it seems now that -America- is the one that's 50 years behind the times.
Inject.
