Rules will always fail. Procedure can always be hacked. And was, you may notice. If it was a suicidal pilot, he could have tricked the the FA into leaving. Maybe he did. No matter how many attempts to manage humans, there can never be enough rules, and never a lack of ways to beat those rules.

Best way to have prevented this would be to NOT HAVE a door that locks out the rest of the plane. Let 9-11 go; that trick won't work again.
Another way? Airlines have cut cockpit crew numbers from 3 (pilot, co-pilot, navigator) to 2 (pilot/copilot) to save money, increase profits and break the unions. That MAY have more than a little to do with the fact that only one member of the flight team is present in the cockpit at times. We've cost cut our way into cheap fares and food-stamp-pilots.... and planes so short staffed that the illness of a single person can kill everyone.

A couple of days ago, a Christian musician family in Phoneix (I think) went obviously nuts and engaged in a massive firefight with police in a big box parking lot they were camping in. Their entire repetoir was about Jesus coming and the End Times - and I'm guessing, since they were all armed, they were the US Government-Obama-is-Satan cultists that are extremely pervasive in the Confederacy (the West is just the suburbs of the Confederacy, has been since the end of the civil war). We have a gigantic armed cult of doomsdayer Dominionists dispersed throughout the country, and the FBI taskforce that monitored it was taken down at the insistence of Congressional confederate Republicans. Our loonies wear ties and Glocks and praise Jesus and fear the negro President. Not even a little bit hyperbolic.

There are no self-drving cars as yet. There are prototypes. And they do fail.

As you noted, we really don't have self-driving cars. Here and there, a self-driving *car*, under escort. SD cars are something Google wants, and now everyone is trying to jump in on the idea, but it really won't work. Most will work, but the failures will be huge. Our capacity for denial will have to ramp up.

Zero. The 9-11 attacks worked because no one expected the hijackers were intending to suicide all along. We now know it, and they cannot hijack planes and succeed anymore, as no one will cooperate.The entire plane would swarm them, and rightly so. So they don't hijack. Zero hijackings prevented, not because of protocols, but because it's damned impossible to succeed, even without steel doors. We've overreacted, and now we've lost an actual plane because of the totally safe terrorism doors that even the commander can't open. Sigh.

The fact that no attack occured gives the talking heads leeway to claim there was no "terrorist attack."

A terrorist is a person who attempts to bring about political change by "illegitimate" (i.e., non-state) violence.

Mass murder is only terrorism if it is an attack on a political entity, or is an attempt to scare a nation's population into something.

Unless someone says, "We're going to keep crash your planes until you do such-and-such", this isn't terrorism. There's no attempt to bring about political change involved, only murder, motive unknown.

Well, another fine mess you've got us into, anti-bearded-terrorist mass hysteria. Surely no one could have anticipated a suicidal or ill pilot locking the other pilot out of the cockpit. A german pilot, so not a terrorist, of course. Need a beard for that.

Don't bother modding me down, Fox News enthusiasts, I can post again, and yet again.

He is an entitled dope, plain and simple. Half the fault is Comcast, because they said they could do it, but half the fault is his, as you said, for not asking the neighbors and the like. Sure, one should be able to get internet anywhere, but there are limitation. In particular the county he is in has only 500 people per aquare mile. The largest city in the county is 40,000 people. Can every house in every rural area have fast internet? Probably not. When someone who works at home and has to have fast internet make one of their primary constraints be that the house already has internet? Can you imagine a trained engineer not being able to make a list of constraints and using a decision matrix to make sure the purchase meets all specs? Years ago we bought a used car, unfortunately the primary constraint was that the car was 'cute'. Of course it ended up being a lemon. If I had made such a mistake, I would have kept it hidden, being afraid the Streisand effect would mean that every future employer would know how incompetent I was.

How long to create a string of 9's?

A couple points here, and note that I do not completely understand the complaints here. Apple has typically sold expensive software. That means that the end user pays more and the developer tends to make more. On upshot of this was that Apple products sold less because it was generally considered as a fact that one not only had to pay more for the Apple brand but also to run the machine. This meant that most developer went for MS Windows, assuming that though writing for MS was a race to the bottom, and knowing that MS could put you out of business any time they wanted, the number of users meant that you would make money. Writing for Apple could also be more difficult. I,myself, have written very few Apple specific programs. I have not really taken the time to learn the library. I appreciate the fact that Apple has taken the time to standardize much of the work so that once the library is learned, writing an application is easier, as long as one is willing to live within the Apple UI. So, as I understand the complaints, Apple has created a new mobile market and new software marketing method that has created million of new customers for developers to sell to,and has actually made writing the applications easier, and developers are complaining about it. Yes, dealing with a UI that is dictating from above is difficult, but that is not different for MS, recall the Ribbon? Yes, dealing with Apple and the App store is probably very expensive. OTOH, I am sure many are like me. I have spent more on applications over the past couple years than I did in the past 10. OOS, no cash cost software, does most of what I want.

NEW SCIENTIFIC DISCOVERY!
For n equal to one million, an O(n^2) algorithm is slower than an O(n) algorithm. Even when the O(n^2) algorithm is run in RAM, and the O(n) algorithm is disk writes being buffered and optimized by the operating system.

I'll take my Nobel Prize now, thank you.

No, the alternative was to wait.

It should be noted that:
  - The Japanese, like the Germans, had their own nuclear weapons program in progress. (That was how they were able to recognize the nuclear bombs for what they were: Bombs were SOME of the possibilities they were pursuing.)
  - While they thought nuclear-reaction bombs were hard but doable, they were actively working on the immanent bombardment of the West Coast of the Untied States with radiological weapons - "dirty bombs" spreading fatal levels of radioactive material. (Remember that much of the US war infrastructure, including nuclear laboratories such as Livermore and the Navy's Pacific fleet construction and supply lines, were on or very near the west coast. The prevailing winds are from the west and able to carry fallout blankets to them.)
  - The primary reason for using TWO bombs, only a few days apart, was to create the impression that the US could keep this up. The Japanese had an idea that making the bombs took so much resource that the US could only have a very few. And they were right.

As I understand it went something like this: There was enough material for no more than two or three more, then there'd have been about a year of infrastructure construction and ramp-up, after which the US could have started with monthly bombs and worked up to weekly or so. If the US could have gotten to that point unmolested, Japan was doomed. But a LOT can happen over that time in a total war - and big projects can get hamstrung when the bulk of the industrial output and manpower has to be used to fight off conventional attacks meanwhile. The idea was to give the Japanese the impression the US was ALREADY that far along.

12 grand with the air conditinoer and some unspecified options that don't prevent it from being stacked up like coffee cups?

For only a couple grand more I purchased, new, an 19 foot travel trailer, with kitchen, (propane stove, micrwave, propane/electric refrigerator) beds for five (if one is a kid) and two are friendlly - six if two are infants), which double as a daytime couch and bedding storage cabinet, TV antenna and prewire, air conditioner, bathroom with enclosed shower, closet, white grey and black water storage for two days if everybody showers daily, a week if they conserve, all hookablel to water and sewer if available, air conditinoier and furnace, lots of gear storage, two nights of battery power (though the microwave and air conditioner need shore power - the furnace runs on the batteries/power conditioner), hitch, dual-axle with tires, awning, etc.

This looks like a very pricey, very heavy, hardshell tent - with some lights, cots, and a big-brother computer monitoring system.

But I bet agencies would love the monitoring system.

My first unix box was an Altos. Don't recall exactly when I got it but it finally died in the late '80s.

The thing burned something like a kilowatt. It also had a four-inch muffin fan - blowing outward. While this sucked dust in all the openings, it was convenient for heat scavenging, AND exhaust. The latter was important in my non-air-conditioned college-town house.

I got a couple 4" drier vents, some drier vent hose, and a heat-scavenging diverter valve (which were big that year - for electric driers only!). Took the flapper valve and rain shield off one of the drier vents, yeilding a fitting that I mounted on the pancae fan's four mounting screws. It coupled the airflow nicely into the drier vent hose, which was essentially exactly the diameter of the fan blade shroud. A few 2x4s mad a wooden insert that went into the window in place of the screen unit, with the other vent in the middle of it. Hooked the two together with the hose, with the diverter in the middle of it, and the third hose segment feeding the hot air register.

In the summer the space-heater's-worth of hot air went out the window instead of into the house. In the winter the hot air fed the furnace distributon, providing a base heat supply to the house with the furnace coming on to "top it off" to the desired temperature.
