one big-ass rotor is far more efficient and generates far more lift than a bunch of small ones.

The trade off is that one big-ass rotor makes a hell of a lot more noise, and is a single point of failure. The multicopter can lose several motors before it's unable to stay aloft.

there is a reason basics of helicopter design has not changed in decades, nothing else makes sense.

The multicopter wasn't feasible in the days of mechanical controls. Computers are better/faster/cheaper, and make things possible that weren't possible in the past.

I recently read that at the same time light bulbs have gotten more efficient, total lighting power expenditure has gone up! Evidently, it's a combination of people using a lot more light when lighting gets cheaper to operate, and more ligthing being installed in general.

I can imagine if we start offsetting global warming we will produce more of its anthropogenic causes.

Would you rather hire a support technician with an arm's length list of industry certifications or a 4 year degree?

Neither, actually. When I interview people, I really don't care about what tickets they've gotten punched. I want them to demonstrate proficiency.

Sorry, but I don't see a problem with anyone shopping for shoes when a hurricane is hitting some other part of the country. She wasn't part of FEMA, she wasn't a member of any search-and-rescue organizations, and dealing with Katrina wasn't her job. What exactly do you propose that she should have been doing to save lives in Louisiana during the storm?

I think we need to take a serious look at the "many eyes" theory because of this. Apparently, there were no eyes on the part of parties that did not wish to exploit the bug for close to two years. And wasn't there just a professional audit by Red Hat that caught another bug, but not this one?
