Amusing as this is, most of it (perhaps not passport numbers -- but how hard can it be to get a new passport as a head of state) is already public information.
I've heard humans taste bad (c.f. animals that take a bite of humans spit us out / don't take another one) and we're probably not very efficient meals compared to fatty seals or muscley fish, so I doubt there is any evolutionary advantage to sharks becoming better human predators.
Qt is publicly developed on Gitorious (https://qt.gitorious.org/), accepting merge requests (with code review). Even if you can't get them to accept patches into the 'official' codebase, you could always just branch it and fix the bugs for yourself
On Linux packages (rpm, deb) are almost always signed by a distribution key, which needs root access to accept.
On Windows binary signing just gives you a company name associated with the exe, which I think is regularly ignored by users
If you're serious about computer security you bring the analysis tools with you, from an independent known-good source, not using anything from the possibly-compromised machine.
Small fuel efficient cars have a huge problematic bug , that has never been worked out. They're dangerous, hard to spot, slow to get out of the way
As evidenced by your own statement it's the huge speeding behemoths that are actually the ones causing the accidents, even if it's those around them that suffer the consequences
A symmetry under X means the system under test is unchanged (ie the same physical laws work, your predictions are still correct) when you do X.
A simple example is the symmetry under spatial translation -- if your experiment still behaves the same way if it's moved a meter to the left, it has "spatial translational symmetry". This symmetry isn't exactly true on the surface of the earth because of variations in the gravitational field etc., but on a small scale for lab experiments it's true, and in deep space it's certainly true. Another example is symmetry under spatial rotation -- your experiment doesn't care whether you face it north or east.
By a very cool bit of maths called Noether's Theorem, you can show that for every symmetry that a system has, there is an associated conserved quantity. So systems with spatial translation symmetry will show conservation of momentum. Systems with time translation symmetry exhibit conservation of energy -- within that system, you can't create or destroy energy. Rotational symmetry results in conservation of angular momentum.
Much of modern physics is built around identifying the symmetries that the universe (or parts of the universe) obeys, the associated conserved quantities, and what happens when those symmetries are broken -- for example the maths leading to the Higgs boson. Currently we believe the universe overall obeys C(harge) P(arity) T(ime) symmetry, that is if you change matter for antimatter, flip everything spatially (as in a mirror), and reverse the direction of time, everything would be the same. This recent experiment shows that time symmetry by itself is not obeyed -- if you only reverse the direction of time, this particular particle collision is not the same.
Photons moving through a medium are "slowed down" by interactions of the electromagnetic field with the atoms of the medium.
Remember that a photon is just localised electromagnetic energy. In a medium, the electromagnetic fields behave differently than in a vacuum, because of the all the atoms with their various charged bits (protons, electrons) -- there is a different "resistance" to changing the field strength because the field has to move the atoms as well. This resistance to changing the field strength is what determines the speed of the electromagnetic wave.
In mathematical terms we say photons (electromagnetic waves) travel at speed c/n, where n is the refractive index of the material, and n is sqrt(epsilon * mu), where epsilon and mu are the relative permittivity and permeability (to electromagnetic fields) of the medium.
A simpler, but wrong, model you might hear is that the photons are being absorbed and reemitted many times as it passes through the medium, all while travelling at c between the atoms, but that can't be really true because otherwise light would be highly directionally spread out after exiting any high refractive index material, but we can see straight through glass and water.
