"They allow me to solve 2nd order partial differential equations in my head and to spontaneously create 4 dimensional images of software structures that I can mentally manipulate."

Dude, teach me! But seriously, although the first boast is pretty much BS, I was surprised to learn that there is actually something called software visualization, albeit in 3D: http://www.cs.colostate.edu/~bieman/Pubs/StaplesBieman99.pdf If only the authors knew about the "smart drugs"!

Anybody know more about this topic?

1. If McAffee could differentiate y = x^2, I'd be surprised.

2. Although it sounds intense, a 2nd order partial differential equation represents either an oscillating sinusoid, a decaying or growing exponential, the product of the two, or a trivial solution: a constant.

Ever pulled on a spring and let it bounced back and forth a few times until it came to rest? Congratulations, you've just "visualized" a 2nd order partial differential equation. Same thing (,Leon). I learned thisin high school 20 years ago and it was invented/discovered hundreds of years ago. It's much harder to actually solve than to "visualize." And it's much harder to apply, to combine with harder math (try solve the wave equation!), etc.

3. 4 dimensional images of software structures (during sex). If you can imagine a call graph in 2-d (doxygen/dot), then imagine the same call graph in 3-d (not flattened), then imagine the same call graph at several moments in time, like a multiple exposure image, congratulations, you've just spontaneously created a 4-dimensional image of a software structure. No phenethylamines needed.

McAffee is all bullshit marketing, swagger and trying to sound deep, tough and cool. If you read his backlog of attempts to do anything on his own on bluelight.ru, you'd feel sorry for the poor guy. He could barely synthesize meth and ecstacy under ideal conditions.

Whatever happened to his B.S. plan to provide a secure anonymyity VPN blackbox-whatever from six months ago? [1]

The 4th dimension is clearly time :)
Why not visualize a graph and be done with it?

Are there really geometric properties that are useful here?

More about the smart drugs or the equation solving?
