The Pentateuch is a work of mythology. There is strong textual evidence that it's a compilation of many different stories and sources over the course of many years. It was most likely written centuries after the events it purports to describe. It is full of wildly unrealistic claims.

Questions:

1. Can you point me where to find more info on UCS ignoring results that contradict their political positions?

2. What "angle" does a nonproliferation shop have in this matter?

3. The article attempts to present some evidence (obviously mostly not to a level required for independent, academic confirmation). So when you see you "see no evidence here", are you saying you need to see it presented in greater detail and to a higher standard, or do you think that the evidence is flawed or misrepresented in some way?

/If/ you know the language and tools well, there is no reason that C++ won't be as efficient in space and time as the equivalent C code. C++ offers real gains to be had over C for embedded software, with rich (if a bit cryptic) zero-overhead abstractions, and higher level constructs that can eliminate entire classes of errors.

As the author points out, C++ offers very significant and tangible benefits, and in the right hands/with the right discipline should be less error prone and result in more efficient code. In my opinion, C++'s greatest benefit for embedded programming is that it has a wealth of abstractions that have no runtime overhead.

The are several reasons that C is still king, but I suspect the main one is portability. Your company may need to be able to port its software to some obscure microcontroller where the only compiler available is a buggy C89 implementation. Or if it has C++ support, odds are that it is inefficient and out of date.

Because of this and other reasons, the labor pool of "deeply" embedded software engineers has a heavy bias towards C over C++. This compounds the problem, reducing the incentive for embedded engineers to learn modern C++.

Incorrect. The four minute window has been known in the public domain for a very long time. http://www.snopes.com/clinton-four-minute-nuclear/

As an American who spent a semester in a high school in France, I remember being shocked hearing our French teacher use "le timing et le planning" discussing our strategy for how to write an in-class essay. This was an ordinary French class for French speakers made up of upper-middle class 11th graders in a stuffy Catholic school.

English loan words (the term itself is valid in French!) are all over the place. "OK" is pervasive. Other examples include "stop", "week-end", "parking", . There are even strange examples where English words are used in ways that make no sense in English. "Footing" means "jogging". "String" means "thong". "Pull" (as in "pullover") means "sweater". "Chewing" means gum. "Baskets" means "sneakers". My favorite though, is "talkie-walkie" where the "l"s are both pronounced.

If you received a blank stare from the supermarket guy, he probably just did not understand what you were saying.

- It stretches the imagination that in the Post-9/11 world, hijackers could access a panel in the cabin without raising passenger and crew suspicion. So the hijackers would have required some way to control the passengers. Smuggling this past airport security is already a huge risk to the operation.

- The northern route may be the optimal route for someone looking to avoid detection, but there is still a massive risk that one of these countries might notice the plane on military or other radar. This would be an unqualified disaster to the sponsors of the operation.

- The most probable final ping locations are so far out that the aircraft was almost certainly at or on the verge of fuel exhaustion. How would the hijackers have known the precise amount of fuel on board? How would they deal with unexpectedly high head winds, or some other in-flight issue? Any crash landing would be difficult to conceal.

The sophistication, danger, and lack of motivation for such an operation makes this sound more like a movie plot than a credible theory.

The AIM-120 uses a datalink to guide the missile close to the target, after which the missile's internal radar emitter goes active, and the missile locks onto the nearest target that it finds. This is because the radar on the missile is not nearly as powerful as the radar on the aircraft. So it's not truly a "fire and forget" missile, at least if a high probability of kill is desired. I believe the Phoenix is similar.

Are there any major libraries that have not yet been ported to Python 3? I'd be interested to hear about others' experiences making the plunge.
