I'm not sure why everyone is concentrating so much on time travel and backward causality. There is a perfectly simple explanation for why it appears that LHC can not be activated: it would destroy the universe if it was turned on (much to the glee of a certain group of people whose sanity I will not question at this time). Therefore, the only surviving universes are those in which some event (no matter how improbable) has prevented its use. The upshot of this is that, once one has a universe-destroying device, quantum bogosort suddenly becomes practical. This would also make cryptography based on one-way functions obsolete, so don't be surprised if the NSA is watching very carefully.

Note: I'm not sure if I'm joking or not.

Asus ships the software you're describing with laptops they sell; it came on mine. It takes a bunch of snapshots of your face through the webcam (you're supposed to rotate your head) and then if it sees your face at the login screen, it logs you in.

So all I need to log on to your computer is a lifesize photo of you, or alternately, your severed head?

I do realize if you hate mother nature, one could just unplug sensors on any factory setup, immediately after testing. But it is less likely to give you any advantages (more difficult to modify for your gain.)

But not impossible. One resistor on the fuel pump stroke sensor of a TDI engine tricks it into allowing you more fuel than the ECU otherwise would: more power but more particulate emissions under some conditions.
