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.
Since it is based on the whole-system simulator Simics -- Yes, it does assume that the app runs in isolation, since all external stuff is just simics simulations.
Reversible computing is a way of computing without (permenantly) consuming energy. Look it up if you're not familiar, because it's pretty interesting.
Anyway, the headline is misleading.
