I envision the scheme as a feedback loop (once an electronics geek, always an electronics geek). Something new comes out, gets itself noticed (by participants in the cloud), gets "fingerprinted" by AV, AV gets fingerprints distributed to users, something new comes out. The tighter the loop, the higher the frequency, the smaller the period (the window of opportunity shrinks for the malware). The proof will be in the pudding - is it scaleable - can it maintain the tight loop under heavy usage (by clients). ....then of course, it depends on internet access even more than other AV's do.

The tower said it was time to turn the plane over to ground control? ....I'll probably be sorry I asked, but why did it? :o/

All the "poles" shifted to the right half plane. Recall the poles and zeros of the polynomial transfer function. The poles being in the denominator. The the "poles" shifted to the right half (of the) plane, it became unstable and flipped over. :-) Nyquist holds that when the poles are in the right half plane, the system feedback loop can become unstable and run to infinity, thus unstable. http://en.wikipedia.org/wiki/Nyquist_stability_criterion Enjoy, fellow nerd(s)!

Nope, never would have guessed that. :o) I remember a demonstration using a dripping water faucet, plotting the regularity of the drops as the flow was gradually increased. This was somehow related to chaos theory and is how I came here. From chaos theory and fractal geometry - to cellular automata -"life" - artificial life - computer viruses. ....and we're back on topic. :oD |
