Hindsight: Reversible Computing
One of the more interesting tech pieces that came out this week has been Hindsight [PDF]. Hindsight is made by Virtutech and is billed as the "the first complete, general-purpose tool for reverse execution and debugging of arbitrary electronic systems." The demos were received extremely well and it just looks cool.
Assuming most slashdotters are lazy f*cks, a condensed explanation: it takes a snapshot every couple of seconds, then when you want to go backwards it moves all the way to the previous snapshot, then runs forwards ignoring sleep() to appear instant.
I mod down anyone who says "I will be modded down for this", regardless of the rest of their comment
