I totally agree with your point, but your math is incorrect. Assuming a nuke hitting a city destroys it, and that each rocket has a 90% chance of hitting is target, the probability, p, of any one city being destroyed is:

p(destroyed) = is p(at least one missile hits) = 1 - p(no missile hits).

p(no missile hits in 50 trials) = .9^50 = 0.00515... leaving p(destroyed) = 1 - 0.05 which is about 95%!
p(no missile hits in100 trials) = .9^100= 0.0000265.. which means p(destroyed) = 99.997%!

which actually proves your point much better!

Agreed, Zimmerman deserves a fair trial (followed by a fair hanging)

Since the state is not charging him with a crime, though, it is completely reasonable (IMHO) for the public to gather and analyze evidence sufficient to compel it to do so. In the mean time, yeah, the guy's life has been torn to pieces. it would suck to be him.

But if I were him I would most definitely *not* prefer my day in court. Not only are there very few circumstances in which I would voluntarily put my life in the hands of a Florida jury, but Zimmerman will still largely be "guilty" in the minds of the public regardless the outcome. Perhaps even more so after an acquittal.

If he is smart he has already fled the country and made a book deal to pay for it. If he doesn't have the brains or the emotional fortitude to leave America he should just end it all, (hopefully by taking a casual stroll down the streets of Camden or Compton wearing a sign, like Bruce Willis' character did in Die Hard with a Vengeance. That would be cool.)

A trial doesn't sound like a smart option for the guy though.

People, many of your implementation examples aren't "either/or" situations. From a practical standpoint you are usually better with a layer of each: security and obscurity, For example, a strong vault that is hidden is better than the same one exposed. A steganographically-encrypted file is safer than that same file in the public domain. How much safer is open for debate, but you are probably safer with both layers in most individual *implementation* situations.

Where the debate comes alive is in two main areas:

1) Design. An open system design tends to be more trustworthy for reasons explained elsewhere. Obscurity in the *design* of any particular layer is usually bad idea (but obscurity in the choice of layers may be a good thing, e.g. what vault you chose or which tested open source encryption algorithm you picked).

2) Testing. If many people use the same system it becomes obvious if a vulnerability is found, and more people are looking for cracks. That same system in a one-off implementation is less obviously secure, even though (paradoxically) it may have been made more secure through obscurity.

I have neither the time nor the inclination to research this, but I'm sure someone said the same thing in the early days of USB.

We'll see if "rumors of its death are premature". I am just happy we are moving towards a faster local I/O standard and applaud Apple for having the guts to champion the technology it thinks is best.

At least the RIAA and MPAA are not grabbing my penis, fondling my beasts or rubbing their hands all over children yet.

This airport theatre is OBSCENE, ethically and morally wrong on EVERY level.

Your passion for civil rights is admirable, but if you have both a penis *and* breasts you may not be the spokesperson we are looking for.

While most "flying car" concepts to date have incorporated detachable or trailerable wings, the Transition has electromechanical folding wings that convert the vehicle in 30 seconds. Test pilot Col. Phil Meteer (retired F-16 pilot) said the first flight went well. The historic event was captured on video."

If it can be defeated with a 2D picture, why not up the ante and ensure that the target is 3d by scanning it with a cheap laser? Sure this could be defeated too, by people fabricating mannequins. If this is within your threat model, then you could require the subject to speak a phrase, then scan the series of facial movements for recognition. The black hats would then have to build an android replicant, requiring the white hats to counter with.... um... typed passwords?
