Comment Re:Formal specifications are pretty useless for th (Score 2) 180

Understanding implies the ability to explain ones position, not merely assert it. You come off like those clowns who go on about proofs of program correctness, but perhaps that's a mistaken impression

Can you give an example of a formal language spec? Are you talking about an actual set of formal transforms to object code or somesuch?

BTW, set-ups like a C compiler written in C are very much in line with Godel statements. There certainly exists source code for which the question "does this compiler compile this source code correctly" cannot have a useful answer as a formal proof (and the examples easiest to contrive would include the compiler itself in said source code).

Try keeping that distance without driving significantly slower than the flow of traffic - unless people pulling in front of you is rare, you can't. Driving at the wrong speed, especially in "bumper to bumper at 70 MPH" traffic creates a significant traffic hazard.

People are a horrendous judge of risk vs reward, especially on the road.

No joke. The primary reason for traffic slowdowns on these highways was rear-end collisions blocking traffic. I'm quite sure that net average travel time was longer because of traffic moving too fast, when you average in the accident delays.

Pave enough lanes and all these problems go away, but people have even worse judgment when it comes to building infrastructure for some reason.

IOS

Georgia Tech Researchers Jailbreak iOS 7.1.2 136

mikejuk writes The constant war to jailbreak and patch iOS has taken another step in favor of the jailbreakers. Georgia Tech researchers have found a way to jailbreak the current version of iOS. What the Georgia Tech team has discovered is a way to break in by a multi-step attack. After analysing the patches put in place to stop previous attacks, the team worked out a sequence that would jailbreak any modern iPhone. The team stresses the importance of patching all of the threats, and not just closing one vulnerability and assuming that it renders others unusable as an attack method. It is claimed that the hack works with any iOS 7.1.2 using device including the iPhone 5s.
It is worth noting that the The Device Freedom Prize for an open source jailbreak of iOS7 is still unclaimed and stands at just over $30,000. The details are to be revealed at the forthcoming Black Hat USA (August 6 & 7 Las Vegas) in a session titled Exploiting Unpatched iOS Vulnerabilities for Fun and Profit:

Ah, you don't get it - I'm guessing you drive someplace more sane. You cannot leave a safe following distance ahead under some traffic conditions. You could try, but there will be a continuous stream of cars pulling into the space you're trying to leave in front of you, and if you slow by too much to try to maintain that space, now you've become a hazard to navigation, endangering everyone else.

. Lane following is simple in that it uses two painted lines to figure out where the lane is and steers to stay between the lines.

My car does much better than that. I've been surprised at how little visual information it needs to determine where the lane is. I does sometimes get confused by zebra crossings, however. It doesn't brake for curves, but it does look ahead and understand curves - if the car "ahead" of me is actually in a different lane, for example, it figures that out and doesn't panic (the first gen system from 10 years ago had problems with that).

Say you approaching a narrow bridge. The bridge has to be identified. How can you identify a bridge if all the information you have is the position of the left side of the lane, the position of the right side of the lane and the distance to the vehicle in front of you?

My car has a variety of sensors, including a camera built into the rearview mirror assembly (so, better visibility than my eyes). It lacks the software to deal with e.g. sharp curves ahead, but the raw data is already available.

Organizations, politians etc. usually don't fuck up in stuff like this.

Your question: how many .... my answer: ZERO.
So how is it in your country? Care to give some examples where health organizations fucked up?

How many professionals have admitted that they fucked up? I've heard a few. One doctor admitted to me that he was wrong to oppose needle exchanges. I read medical journal articles every week in which doctors say, in effect, "We thought this would work, but this shows we were wrong."

The sign of a good scientist is that he's willing to admit it when he's wrong.

Do you really believe the USA governments health agency carries an US citizen into the US if it was not perfectly safe? In what paranoia 1984 world do you live?

Unfortunately the US Congress just voted to prohibit federal funds from going to needle exchange programs. They prohibited medical marijuana research even after AIDS patients found that it could stop them from dying from AIDS wasting syndrome (according to a lecture I heard from Don Abrams, who was treating them). Bill Clinton fired Joycelin Elders for saying that sex education courses should teach about masturbation. They prevented the graphic cigarette warnings which were so effective in Australia.

I've talked to government public health officials, and I've heard them deflect controversial questions. I can see them thinking, "If I told the truth, I'd get fired, and then I couldn't accomplish anything."

I'll probably get fired for saying this, but: America is not perfect.

Social Networks

Google+ Photos To Be Separated From Google+ 114

An anonymous reader writes "Speculation on the eventual shuttering of Google+ has once more risen with news that Google+ Photos will soon be developed and run separately from the social media site. This news follows observations that Google+ "was barely mentioned at Google I/O 2014, while there were 15 sessions dedicated to the service in 2013" and that the company has ended its controversial real name policy. Google Hangouts was also separated from Google+ at the end of July." I've actually heard several people praising Google+ lately; scaling it back to "just a social stream" probably fits into some kind of corollary to Murphy's Law.

You try so desperately to connect those two unrelated concepts; apparently under the belief that you can force them into association by repetition alone. I would point out to you that there were actually people from the original occupy (wall st.) movement who actually wanted to run against President Lawnchair but I don't expect that would slow you down any.

No no, the desperation is 100% on your end, I assure you.

I would be genuinely interested in knowing why you are so sure of this.

Strong correlation with consciousness during the previous 6 years, I suppose.

So, then, ~35% of the public - or 80%+ of your own party - supporting impeachment are sufficient in your mind to venture down this road? Not many people would ordinarily consider such a group to be an accurate assessment of "the public".

Your continued desperation to attach ownership of the GOP to me is. . .quaint. The only numbers that are going to matter are the results of the November elections.

If the GOP are invertebrates, then the democrats are - at most structurally - pond scum. They haven't stood for much of anything as a party in over a decade.

Aw, c'mon, boss: both stand for the increase of Federal power.

What I did was still more than you have done to attempt to fill in your cavernous gaps of knowledge.

Oh, OW! Oh, that hurts! Oh, the suffering! Imma go cry now.

Comment Re:Actually they ARE working on some treatments. (Score 4, Informative) 409

Actually there ARE some experimental treatments and antivirals, both general and specific to Ebola, being worked on. At Emory, in particular. (It's their business.)

In fact, according to previous reports, THIS GUY was working on them. And he had ONE dose of one of them WITH him.

Unfortunately, when he and a colleague both started showing symptoms, THIS GUY gave the ONE DOSE to the OTHER GUY.

Actually, the infected doctor, Kent Brantly, gave the treatment to another missionary, Nancy Writebol, and she's also being evacuated on that plane. http://www.washingtonpost.com/... They haven't announced what the treatment is, but it might have been IgG blood serum http://www.livescience.com/471... separated from the blood of one of the other victims. Or it might have been a new untested adenovirus vaccine, which works (on monkeys) even after they're infected. Or it might have been a monoclonal antibody. Or it might have been an experimental RNA virus. http://www.nature.com/news/ebo... I can't understand why they're keeping it a secret.

These untested treatments are all desperate measures. From what I've read in the New England Journal of Medicine clinical cases, these are the kind of treatments that they use when everything else fails, the patient is dying, they don't know what else to do, and there's nothing to lose.

As I understand it, the odds are against it, but they're the best doctors in the world, and I hope it works.

I also don't understand why they're bringing them to the U.S. The only treatment is supportive care. I think they also have planes that are set up with a transportable ICU, so they should be able to treat them on site.

There is a risk of the virus getting out, no matter how careful they are. They're doing this all for the first time. One problem is that handling a case like this is so complicated, and you only have to make one mistake. An ICU is full of equipment. Since ebola can't be treated, an epidemic spreads until it kills off so many of its victims that there's nobody left to infect, and it burns itself out.

With SARS, a lot of medical workers, particularly nurses, got infected, and they were a large number of the fatalities.
