P ≠ NP proved?
Oh my. Somehow I missed this one from earlier this month. A guy from HP Labs called Vinay Deolalikar claims he has the proof. P ≠ NP. I'm nowhere near clever enough to follow his arguments (see http://www.hpl.hp.com/perso... for a synopsis), but I understand the impact. If he is right, then in a sense, nothing changes. It's just that we will now know for sure that there is no magic formula that will revolutionise the efficiency of our software. The proof will ......

UPDATE: 22/09/2010. I have posted an update on this issue. My root problem turned out to overheating, although I still advocate a number of optimisations for VirtualBox. I have a Dell laptop with 8GB RAM and a dual core processor running Windows 7. I use my machine quite intensively. Quite often I run virtual images under Oracle's VirtualBox.
