I'm not speaking of the right answer, I'm speaking of what teachers and councilors are saying to the students (many of the parents as well).

Perhaps they SHOULD be talking to graduating high schoolers about the substantial risks of student loans and the benefits of avoiding them even if it means taking an extra year or two, but they're not.

Stupid or inexperienced?

Even back when I was about to graduate high school, the message was clear that the next step is definitely to get into a school (any school) and you will be needing a student loan or three. That was a strong message from pretty much any and every "adult influence" in your life. And that was before helicopter parenting and other think of the children measures had removed many of the opportunities a teen might have to operate semi-independently where they would gain some experience that might help them see through the scam.

Even a session wouldn't help. Many communications over the net are machine to machine. Also there's the whole solve the CAPTCHA by mechanical Turk (paid for with copied porn).

I wouldn't be surprised if within a year of setting up such a scheme, CAPTCHAs for certain websites would develop a very high failure rate.

How would a search engine spider the web?

Sorry, there's really no difference. An attacker can easily appear to be the browser of their choice.

Going to CAPTCHAs that would actually work would be as bad as shutting the routers off and going home. Are you really willing to solve a captcha every time a daemon on your system wants to do a DNS lookup of check in with a time server? Besides, they can actually be solved by putting up a porn site (solve the captcha, see the next image).

Comment Re:IoA (Score 2) 114

When people talk about an IPv6 address being 128 bits they're technically true but they miss the bigger picture. In practice you can't assign anything smaller than a /64 so really there are only 64 bits of address space as we think of it today. 1 IPv4 address hosting a subnet with NAT vs. an IPv6 /64 prefix are roughly equivalent. It's still way more address space than we'll ever reasonably need, but not quite as ridiculous as it looks at first glance. This also means that 64 bit machines (most of them these days) can compare addresses easily, since you can often ignore either the top or bottom half of the address.

Submission + - Should we bring extinct species back from the dead? (

sciencehabit writes: For decades the notion of “de-extinction” hovered on the scientific fringes, but new advances in genetic engineering, especially the CRISPR-Cas9 revolution, have researchers believing that it’s time to start thinking seriously about which animals we might be able to bring back, and which ones would do the most good for the ecosystems they left behind. Science Magazine explores why and how we might do this, which animals might be first, and the big risks involved.

Submission + - F-35A Catches Fire at Mountain Home Air Force Base (

theweatherelectric writes: Writing for Defense News, Valerie Insinna reports that another F-35 has caught fire during an exercise. She writes, "The incident took place at around noon and involved an F-35A aircraft from the 61st Fighter Squadron located at Luke Air Force Base, the service said in a statement. No serious injuries seem to have been sustained by the pilot or nearby crew.

'The pilot had to egress the aircraft during engine start due to a fire from the aft section of the aircraft,' Air Force spokesman Capt. Mark Graff said in an email. 'The fire was extinguished quickly. As a precautionary measure, four 61st Aircraft Maintenance Unit Airmen, three Airmen from the 366th Maintenance Group and the 61st Fighter Squadron pilot were transported to the base medical center for standard evaluation.'"

Comment Re:Van Allen radiation belts (Score 1) 141

I can't claim to know the cause, but I have seen one proven case of a bit flip affecting processing on a machine that ran fine before and after the incident. Since it was doing batch processing I was able to re-run the job with identical inputs. It never made the error again.

Could have been a cosmic ray, alpha decay, power glitch that oddly didn't affect the other machines on the same circuit, who knows?

Submission + - FDA, Other Scientific Agencies Embargo News (

frank_adrian314159 writes: What if you were a reporter and couldn't check on the veracity of a science story before you reported it? That's the Faustian deal science reporters make every day with the FDA, medical publications, and other scientific organizations they depend upon for their "scoops". If you break the code of omerta or any of the embargoes, you can (and will) be blackballed from future information. Salon has the full (and lengthy) story here. Needless to say, this is probably not the openness most people think of when they hear the term "science reporting".
