I'd wager that it's either an embarrassing use case, or that he wanted to avoid having people tell him how he should have done it - can't do that with any level of confidence if you don't know the circumstances.
I will say that, despite its many shortcomings and after I was able to overcome the netbook-induced Atom stigmas, I really do like the Atom for small-business NAS applications.
Sounds like a disincentive for paving with impenetrable ground cover. Rainfall is not absorbed when the ground is paved. Instead, it collects and increases flash flood risk. To compensate for this, the rainfall collection and pumping infrastructure must be more robust. Perhaps this tax will be spent on such improvements?
These are very likely long exposures that captured groundings over time. It'd look much less impressive in person, and more in line with what you've seen reproduced.
The new A8 looks quite a bit like the new Lincoln Continental. If you integrated the door handles on the A8 with the window trim, it'd be hard to distinguish between the two cars from an appreciable distance - at least the rear, profile, and 3/4 views. The rear light arrangement, the integrated dual exhaust ports, the silver trim character lines, even the A/B/C columns.
