Good point, but regarding double dipping, a lot of zombie machines out there were infected due to exploits for which patches already existed... they just never got patched.
I dunno, this sounds a bit like the argument over whether or not one should negotiate with hostages or terrorists... Once the black hats figure out that their exploits are being "rescued", two things will happen:
* Prices ("demands") will go up; these companies have deep pockets / lots of resources after all... want a chopper and $2 million?
* The exploits will be re-sold... some exploits can't be patched immediately, and even if it can, millions of machines will remain unpatched over their lifetime. So if you can make ten grand from randsom, you can pick up some extra cash on the side by pimping out your victim.
Maybe I'm taking the analogy too far.
And for those who don't want to read all that...

It sounds very much like conventioanl QFT viewed through 1930s eyes... Especially the part about waves cancelling. Expectation values of commutation relations vanish (decay exponentially) outside the lightcone where they are acausal.
Ignoring that a TeV is a unit of energy and not power, that's about 2e-6 joules... a flea sneezes more energetically than that. They mean that individual particles can reach this energy. Actual power consumption is probably enough to power a dozen DeLoreans.
I suppose they could. According to Wikipedia these cost about $5 million each and take 4 months to produce. Gone are the days when NASA had the budget for that sort of expenditure I guess.
Yes, since the constituents of the object have more kinetic energy. In the same way that a hot potato weighs more than a cold potato. Relativistically speaking, the total "apparent" (energy, momentum) 4-vector of the object is equal to the sum of the 4-vectors of the individual particles, so while the momentum can add up to zero, the energy component of the 4-vector is increased. From there, E^2 = m^2* tells you that energy ~ mass. In your example of the atom or subatomic particle, you also have to take into account the contribution of the binding energy (potential energy), which actually has the opposite effect, making atoms lighter.
This problem went away for me when I recreated my firefox profile (which had been around since the 0.3 days or so). I then imported my old bookmarks, and it worked like a charm since.
My Firefox profile has been around since the single digit version number days, and a lot of tweaking has gone into it to fix old bugs like the search box popping up when you don't want it to (typeahead find?). I experienced this sort of crashing in Firefox 2.0 since the first RC and somewhat less but still prevalent with the final release (I had all my extensions disabled). Thank god for session recovery.
So I bit the bullet and recreated my firefox profile (basically just imported my old bookmarks), and it works like a charm. Not a single hang since. YMMV.
There are dualities between string theory and quantum field theory that allow intractable QFT calculations to be performed using string theory methods. In some cases, millions of Feynman diagrams can be summed up by translating the problem into a string theory problem. While some people view string theory as being largely made up, theoretical physics is all about constraints. In order for things to be physically consistent a large number of aspects must fall into place. Even if string theory doesn't eventually fit the bill, the investigation thereof allows us to sample the space of theories, so to speak, so get an idea of what the ultimate theory will look like.

...has deemed time travel impossible.
I do!
I was much happier believing you meant "pirate ninjas"... maybe I won't see POTC after all...

Nowhere near as cool as this guy: http://www.internationalhero.co.uk/c/capcana1.htm!
