Why does anyone require 'due diligence' and fact-checking against insane violent assholes like these Sunni extremist fuckstains that laughingly call themselves the 'Islamic State'

Well, for a start, to make sure that's who's actually responsible. (Not saying they're not - or that they don't deserve action anyway, but if it weren't them, then another guilty party could be getting away with no action due to a lack of due diligence)

Here is a perfect example: Toronto Games Critic [Veerender Jubbal] Falsely Linked with Paris Attacks .

Comment Re:The fastest unpaced bicycle (Score 2) 21

Just pointing out that the focus of this attempt, and thus the record category, is explicitly the human-powered aspect; they set their sights on the human-powered land speed record because it aligns with their ambitions and mission statement. To them, the speed is really just a metric to measure the efficiency of their design. AeroVelo is all about what we can achieve using the power output of the human body, which is why their world-first human-powered ornithopter and human-powered helicopter were also Big Deals(TM).

Slip-streaming would take away from the human-powered aspect; to them, it's about a lot more than just the speed. That's not to take away from other record categories, which are all impressive in their own right; I'm just trying to explain why AeroVelo targeted this one specifically and why the fact that it is unpaced (and even the very low limits on legal wind) is part of their identity.

"Vaporizing" satellites doesn't really help you. All you've done is split one big satellite into a whole bunch of tiny satellites, each of which is still moving at orbital velocity (thanks, conservation of momentum..). Except now you have a dispersed debris field moving at orbital velocity instead of a single satellite.

Monster's general counsel said the move would "significantly disrupt Monster's business and that the two companies had worked well for years, with Monster paying Apple more than $12 million in licensing fees since 2008."

So, this is a philanthropic move from Apple, then. Monster are bottom-feeders that prey on the naive, and the world would be a better place without them.

Local overheating, hard radiation hits; voltages can actually be pretty high depending on string length and your orbit. Spacecraft experience high differential charging depending on the plasma environment through which they are passing. Outright cell failure is relatively rare though; typical failure mode is degradation below the operable voltage.

Comment Re:Satellites (Score 1) 403

I don't know the underlying physics, but radiation (including solar radiation), especially at high temperature, causes the junctions in the solar cells to become less efficient over time. Less efficient cells generate more heat, which increases the rate of deterioration. Eventually the open-circuit voltage of the cell drops so low that it is below your spacecraft power bus and you stop being able to pull power off the array.

Another failure mode is when individual cells short-out, which happens when the junctions just straight up burn out. This generally results in the loss of individual cells, which lowers the voltage of the array or, depending on architecture, may take down that cell's entire string.

L1, L2, and L3 are weakly stable; think being at the top of a parabola. It doesn't take much effort to keep yourself there, but you do have to reject orbit perturbations. L4 and L5 on the other hand are actually stable, which is why trojans collect there. Note that there aren't any natural equivalents to trojans at L1, L2, and L3.

It is easier to change the specification to fit the program than vice versa.
