That's how it works, but not the key. The important thing is that the SK can't be understood by a computer program because it's a CAPTCHA, and therefore can't be brute forced.

...is that the whole password cannot be decrypted in an automated way, because even though a computer program would quickly guess the short password (SP), the fact that the strong key (SK) is stored as a CAPTCHA prevents the computer program from obtaining it, even with the correct SP.

The point is not (as some seem to believe) to help the user memorize a longer password by storing part of it for him. This approach actually wouldn't introduce any added security, as you still have a single point of failure (the memorized short password).

More like international legal hegemony.

I dual boot Windows 7 HP and Ubuntu 10.04 (Lucid Lynx) on an Asus Eee PC T101MT. It's got a resistive touch screen that is not well supported by vendors, nor by Microsoft. While Windows7 does respect the 1024 pressure levels the screen can read, inking is extremely slow as compared to that in Ubuntu, and the pressure levels don't translate to Photoshop or the GIMP. The only programs that seem to recognize the pressure levels are Windows Journal and OneNote, neither of which is intended as an artist's tool. By contrast, Ubuntu has very fast smooth inking, and a wonderful paint program with full support for the pressure levels (MyPaint). Considering that I purchased this netbook for the explicit purpose of being able to paint as well as take notes and read books, etc., Ubuntu saved the day for me.

At this point in time I've got everything working spectacularly on this thing- from painting with pressure levels to reading Kindle books, multitouch to two-finger scrolling, media keys to Wiimote as gamepad, handwritten notes to DropBox, Skype to Arduino development, even handwriting recognition and an OSK. You name it, I've got it going on this thing, all thanks to Ubuntu. I am quite willing to say that, although almost every other computer I've ever had has in some way (usually proprietary hardware-related) ran better with Windows and in some way better on Linux, Ubuntu far outshines Windows on my T101MT in every way.
