Time frequency uncertainty is a known issue in signal processing, and an explanation can be found early on in A Wavelet Tour of Signal Processing, for example. The post you are replying to stated that this is a fundamental property of the discrete Fourier transform, which it is.
To be able to personally tailor medicine to an individual, you need an effective diagnostic mechanism, and an effective way to decide, based on the diagnosis and the patient, what course of treatment will work. Trying to do this on the basis of a patient's genetics is unlikely to be effective in the near future, if at all.
Te begin with, studies of the kind we see today tend to give results like 'gene X affects incidence of disease Y by n%'. To rely on this for a diagnosis and treatment amounts to a guessing game, and the number of such n% guesses compounded together will cause accuracy of the diagnosis to be little better than random chance, yet appear to have the certain blessing of the medical establishment. Establishing the effect of a gene is, in any case, far less certain than seems to be made out, because there is little understanding of how an altered gene causes a problem even if a correlation is detected.
I fear personalised medicine is the road to mass Russian Roulette medicine, and I hope the 'brave new and shiny' factor doesn't cause it to be overly relied upon.
To learn about aperture and shutter speed, try taking a DSLR out for some night time shooting where you play with apertures from f/5.6 to f/16 and shutter speeds of 10s to 30s (you need a tripod obviously). Basically there are three variables to balance: sensitivity, aperture and shutter speed. Once you have a feel for how that works, use aperture priority in daytime to let the camera choose shutter speed automatically based on light and get a feel for the choices the camera makes (you can look at the screen at the back to see the camera's choice changing). Then play with shutter speed for capturing something like moving cars (just to play with the camera rather than serious shooting). Once you've done this, play with the other features of the camera, but understanding sensitivity, aperture and shutter speed is a must for anybody who goes beyond point and shoot.
It is optical, but is the equivalent FOV for a 35mm camera. Actual focal length is something like 5mm-90mm (just a guess). They manage this by having a tiny sensor that seriously compromises quality compared to a DLSR -- I was suprised just how much better photos my D3100 took when I got it a few months after my Lumix.
Hitler, Stalin and Pol Pot didn't need God to believe in their version of the truth that justified mass killings. It is easy to blame belief in God where one sees atrocities, but there is too much evidence that atrocities happen with and without belief in God, it's just whatever aspects of the underlying culture a tyrant picks up to justify their actions, and because theistic religion is present in the culture, it gets drawn on for justification of evil.
I run Unity, but I use the Guake console and have a 'u' command so that I press F12 to get the console and 'u m' for my mail program, 'u c' for chromium, etc. I have an n command so that n f.pdf launces evince, n t.tex latex's it etc. I doesn't reflect well on UI design that I like linux because a drop down command line console is a useabiliy feature I need.
If you haven't read The Unix Haters Handbook, it's a great read for all those *nix lovers. I say this as one who prefers Linux for most everyday stuff.
I remember when I first installed Linux in 1995, which came on a cover CD with essentially no instructions. I had to reinstall two or three times and watch carefully the list of packages installed to get an idea of what to type. I took a while to find my way around the/bin and usr/bin stuff, and it took me a week, and the confirmation dialog in the openlookalike file manager (do you want to Remove), including getting X up and working, before I guessed that rm and not del or era was the command to delete a file. I guessed man correctly, having seen that the package man was installed and the installer screen indicated that this was the manual. But I was determined to play with this new toy, and few users today will try so hard. What fun.
Apple are dumbing down the Mac, moving it away from being a high end professional computer, turning it into an overgrown iPad. Microsoft are turning Windows into an oversized Windows Phone OS. PCs are turning into consoles, and it is the serious personal computer that is threatened with extinction.
Though for starting out, it will be a while before you need what the D7000 gives over the D3100. The D5100 is also worth a look if you have the cash, though if you plan on spending more than a D3100 and don't need the tilting screen of the D5100, possibly the D7000 is the next step up.
I have a Lumix FZ100 and the quality sucks compared to either my Canon S95 or my Nikon D3100. If you want to capture things that are moving, the shutter lag on a non-DSLR tends to get in the way: you have to be prescient to know to press the shutter half a second before the shot you want to take appears: DSLRs are much quicker to respond. As a starter DSLR there is no need for more than either a D3100 or a Canon 550D. If portability is an issue, get a good compact such as a Canon S95 -- I love the fact that this has a face-autofocus that focuses the faces in the picture wherever they are, something a DSLR will probably never do.
I find that the biggest advantage of a DSLR is in being able to get a shot of something that is changing -- when you press the button on a DSLR, that is when the photo is taken -- with every compact I've used, there is a roughly 0.5sec lag which means that what you get a shot of is not what was in front of the camera when you pressed the shutter release. On the other hand, a camera you can have with you at all times is terribly useful. For this reason I have a Nikon D3100, which for a first DLSR is ideal, and a Canon S95 which is a great high quality compact.
Though the flattening effect of telephoto must be taken into account. If you want to flatten the perspective, step back and zoom in, if you want the opposite, step in and zoom out. I find that 50mm is the shortest lens that's any good for people's faces, and 35mm is great for scenes. I have a 18-270 Tamron, which is fine when you want the zoom and quality isn't so important (photos are not as alive as those from even my original 18-55). Basically a couple of primes are great for those times when you want better quality and decent bokeh, whereas a travel lense (e.g. 18-270) is useful when you are going for a walk and don't want to have to change lens.
I have a bridge and, unless you really need the zoom, the picture quality is let down by the size of the sensor, resulting in much more noise than you get with SLRs or a high-end compact.
Not to mention that superzooms have tiny (1/2.33) sensors. This causes much noise in the images which precludes blowing them up to anywhere near the size that the megapixel count would have you think.
A straightforward mod would be to have a truecrypt volume concealed in the least significant eight bits of a long 24bit wav file that you could obtain as, e.g. a 1hour+ trance mix from beatport (that would be 16bit, so the data would be inaudible). Slowdown would be tolerable given modern hardware.
People say that about science vs religion, but going by the evidence thing, many areas of what is traditionally called science would be better described as religion. Even physics requires one to take certain foundational assumptions in faith before one can talk of interpreting evidence, and other areas of science are much more apt to preach the current popular theories as dogma and dismiss counterevidence. If only other areas of science were as rigorous as physics.

Better delete that crypto volume ;-)

I doubt China or Russia would follow suit, and this kind of stupidity is just what will give them the lead in computer tech.
Try this or this for examples of a real Western religion.
And eliminating gasoline will prevent useful applications of it, in effect throwing the baby out with the bathwater.

'You will effectively not exclusively own root on a windows box' -- like the TrustedInstaller user on Win7??
Or 'killall men' or 'kill husband' (or even 'kill -9 ex-husband') etc.
