It's basically the soletta from Red/Green/Blue Mars (and probably other earlier references too) only focused the other way. You don't even need to cover the whole sun, just need to reflect away a small % to make a difference in the heat balance equation. A small shade in the middle, or a ring that covers just the perimeter, or a distributed/swarm solution.

We're nearing the point that just solving the C02 problem isn't enough due to the "in the pipeline" heat budget already on its way. Looking for GeoE solutions is mostly a matter of deciding that the amount of heat rise we'll coast to isn't acceptable even if we drastically reduce C02. Fast CO2 cut-off vs. more GeoE to give ourselves more time probably depends on politics as much as economics, unfortunately.

You are being sarcastic. But the mistake the advocates make is assuming that the machines must both assist humans in filling out the ballot, and recording that ballot. Machines are good at the former (input validation, audio UIs, etc.) and outputting something that doesn't rely on human handwriting/chad-punching. But the latter requires too much trust in something uninspectable. Instead just use the machines to make error free ballots, which are kept as a paper trail, and tallied just like the ballots of yore were.

Or better yet, feed the ballots into two+ independently built/owned/designed counting machines and investigate if the answers are ever not 100% in agreement, if you want your results faster. You can even go back and hand count later in an audit.

Some of the confusion is that the original description is defined recursively in a way that 'c' only shows up once, and the initial value is not c. z[i] = z[i-1]^2+c. But because z[0] is defined = 0, you can effectively rewrite the sequence in terms of just 'c' starting from the second. The downside is that at first it might LOOK at first glance like the previous term is being added, which is why I like the recursive form.

Also, by not starting from 0 you miss out on a cool connection: for a given fixed C, the graph of convergence for non-zero choices of z[0] over the complex plane gives you a Julia Set. With the neat property that Julia Sets from C inside the Mandelbrot set are fully connected and Julia Sets from C outside the Mandelbrot Set are sparse disconnected Cantor spaces.

But what objective did they achieve? They didn't get a new customer in him. They created headache and strife out of incompetence that didn't gain themselves anything in the process. If anything, telling him the truth would have caused him to look elsewhere for a home and become a (happier) customer all the faster.

And the guy who sits next to those other people you are constantly coordinating and discussing issues with? The guy who needs to concentrate hard on a one-man project? He is freaking hating it, and by extension, you. Headphones don't eliminate all distraction cues. And you know what? You'd still be able to do your collaboration shtick in cubicles or offices by walking up to folks when you need to.

Open plan might work for some places, but its a fad being adopted by managers following trends without evaluating if they truly make sense for their shop.

That depends on the board design. If the MoBo designer didn't balance the copper density well top-to-bottom it will warp the whole damn thing as if it were a thermostat. Technical term is "potato chip-ing" the board. Seeing as how the initial problem occurred under temperature loads bad design isn't outside the realm of the possible. Or they cheapped out and used thinner copper layers that didn't spread the heat evenly enough laterally. (Though as others have pointed out it may be something INSIDE the chip packages not the MoBo. Also 340F isn't enough to melt solder, particularly lead-free.)
