Submission + - New formula massively reduces prime number memory requirements.

grcumb writes: Peruvian mathematician Harald Helfgott made his mark on the history of mathematics by solving Goldbach's Weak Conjecture, which every odd number greater than 5 can be expressed as the sum of three prime numbers. Now, according to Scientific American, he's found a better solution to the Sieve of Erasthones:

In order to determine with this sieve all primes between 1 and 100, for example, one has to write down the list of numbers in numerical order and start crossing them out in a certain order: first, the multiples of 2 (except the 2); then, the multiples of 3, except the 3; and so on, starting by the next number that had not been crossed out. The numbers that survive this procedure will be the primes. The method can be formulated as an algorithm.

But now, Helfgott has found a method to drastically reduce the amount of RAM required to run the algorithm:

Helfgott was able to modify the sieve of Eratosthenes to work with less physical memory space. In mathematical terms: instead of needing a space N, now it is enough to have the cube root of N.

So what will be the impact of this? Will we see cheaper, lower-power encryption devices? Or maybe quicker cracking times in brute force attacks?

Oh you poor deluded soul ...

"Free-Speech Zones" ring any bells? Ya know, those nice fenced-in places for protestors to cool their heels, far enough away from any event that the general public won't be bothered by them? First used sometime 'round the 60s? Also a nice place for less "cooperative" journalists to get tossed into?


Submission + - SPAM: A Medical Mystery of the Best Kind: Major Diseases Are in Decline

schwit1 writes: Something strange is going on in medicine. Major diseases, like colon cancer, dementia and heart disease, are waning in wealthy countries, and improved diagnosis and treatment cannot fully explain it.

Scientists marvel at this good news, a medical mystery of the best sort and one that is often overlooked as advocacy groups emphasize the toll of diseases and the need for more funds. Still, many are puzzled.

“It is really easy to come up with interesting, compelling explanations,” said Dr. David S. Jones, a Harvard historian of medicine. “The challenge is to figure out which of those interesting and compelling hypotheses might be correct.”

Of course, these diseases are far from gone. They still cause enormous suffering and kill millions each year.

But it looks as if people in the United States and some other wealthy countries are, unexpectedly, starting to beat back the diseases of aging. The leading killers are still the leading killers — cancer, heart disease, stroke — but they are occurring later in life, and people in general are living longer in good health.

Colon cancer is the latest conundrum. While the overall cancer death rate has been declining since the early 1990s, the plunge in colon cancer deaths is especially perplexing: The rate has fallen by nearly 50 percent since its peak in the 1980s, noted Dr. H. Gilbert Welch and Dr. Douglas J. Robertson of the Geisel School of Medicine at Dartmouth and the Veterans Affairs Medical Center in White River Junction, Vt., in a recent paper.

Comment Further cloud integration? (Score 1, Insightful) 88

"Storage space maxed out? No problem. macOS Sierra can help make more room by automatically storing rarely used files in the cloud and keeping them available on demand. It can also help you find and remove old files you no longer use. So there’s always room on your Mac for new files and the ones you’ve used most recently."

Uhm, no. I do NOT want or need anyone managing my storage for me, or to deal with service outages leaving my files unavailable. Thanks, but no thanks. Take your cloud service and shove it sideways up your ass until you can taste it.

How about when Windows Update helpfully reverted this change for you?


How about when Windows Update helpfully started the upgrade process on domain-joined systems, despite MS claiming it wouldn't?

MS keeps demonstrating that they can't be trusted, and I for one am tired of having an adversarial relationship with them.

Submission + - State Department to release Clinton TPP records ... on date that doesn't exist (muckrock.com) 1

v3rgEz writes: Last July, reporter David Sirota filed a FOIA with the State Department for all communications sent by Hillary Clinton referencing the Trans Pacific Partnership. After an initial estimate that records would be ready for release by April 30th, 2016, just last week the agency wrote that due to unavoidable delays, that would have to be revised ... to November 31st, a date that is not only after the election, but which doesn't actually exist.

Submission + - About 95 % of U.S. transnational internet backbones allegedly tapped by NSA, CIA (cryptome.org)

Dave_Minsky writes: James Atkinson with Massachusetts-based Granite Island Group, an "internationally recognized leader in the field of technical surveillance counter measures," wrote in an email to Cryptome.org on June 10 that roughly 800 of the internet backbones (around 95 percent of U.S. backbone fiber) that criss-cross the oceans are tapped by U.S. intelligence agencies such as the NSA and CIA, which have installed equipment at point-of-entry stations throughout the county's shoreline.

The taps are passive but are converted to active filtering nodes, enabling traffic disruption and injection, Atkinson wrote.

What's even more alarming is Atkinson says the telecommunications companies that own the cables are "silently cooperating by not implementing point-to-point bulk traffic encryption."

"This means that all the talk about legal instruments, NSLs etc. is immaterial, and that Tor traffic is practically vulnerable," Atkinson wrote to Cryptome.


Submission + - Can SourceForge Win Developers' Trust Back? (helpnetsecurity.com)

Orome1 writes: SourceForge is under new ownership and management (again!), and their plan is to return the service to its former glory. Once the preferred source code repository and distribution platform for FOSS projects, SourceForge has been blacklisted by many of its former users due to deceptive ads that looked like download buttons and questionable revenue generation schemes. In January 2016, the site was sold to web publisher BIZX and the new owners have started cleaning it up. “We removed the DevShare adware bundling immediately, moved the site to https, and we built and rolled out a feature where we partnered with Bitdefender to scan every project for malware," said Logan Abbott, one of the BIZX owners and the president of the SourceForge Media subsidiary.

Submission + - Laid-Off Americans, Required to Zip Lips on Way Out, Grow Bolder (nytimes.com)

Indigo writes: New York Times: American corporations are under new scrutiny from federal lawmakers after well-publicized episodes in which the companies laid off American workers and gave the jobs to foreigners on temporary visas.

But while corporate executives have been outspoken in defending their labor practices before Congress and the public, the American workers who lost jobs to global outsourcing companies have been largely silent.

Until recently. Now some of the workers who were displaced are starting to speak out, despite severance agreements prohibiting them from criticizing their former employers.

Submission + - Companies Finding It Harder To Conceal H1-B Abuses (nytimes.com)

JustAnotherOldGuy writes: In America, it's common practice to make severance pay for laid-off workers contingent on signing a "nondisparagement clause" that prohibits workers from ever speaking ill of their former employers. But as more and more layoffs are precipitated by illegal practices like hiring H1B visa-holders and forcing existing workers to train them as a condition of severance bonuses, workers are growing bolder and refusing to sign gag-clauses — or breaking them and daring their former employers to sue. Marco Peña was among about 150 technology workers who were laid off in April by Abbott Laboratories, but he decided not to sign the agreement that was given to all departing employees, which included a nondisparagement clause. Mr. Peña said his choice cost him at least $10,000 in severance pay. “I just didn’t feel right about signing,” Mr. Peña said. “The clauses were pretty blanket. I felt like they were eroding my rights," he revealed in an expose by the New York Times.

Submission + - Worst Mass Shooting in U.S. History (cnn.com) 17

An anonymous reader writes: From CNN:

"Fifty people were killed inside Pulse, a gay nightclub, Orlando Police Chief John Mina and other officials said Sunday morning, just hours after a shooter opened fire in the deadliest mass shooting in U.S. history. At least 53 more people were injured, Mina said. Police have shot and killed the gunman, he told reporters.

The shooter is not from the Orlando area, Mina said. He has been identified as Omar Saddiqui Mateen, 29, of Fort Pierce, about 120 miles southeast of Orlando, two law enforcement officials tell CNN.
Orlando authorities said they consider the violence an act of domestic terror. The FBI is involved. While investigators are exploring all angles, they "have suggestions the individual has leanings towards (Islamic terrorism), but right now we can't say definitely," said Ron Hopper, assistant special agent in charge of the FBI's Orlando bureau."

Submission + - FBI: Clinton approved CIA drone assassinations though unsecured personal server (salon.com)

gluesniffer writes: An explosive new report reveals just what it is that the FBI is looking to: emails in which then-Secretary of State Clinton approved CIA drone assassinations in Pakistan with her cellphone. From 2011 on, the State Department had a secret arrangement with the CIA, giving it a degree of say over whether or not a drone killing would take place. Under Sec. Clinton, State Department officials approved almost every single proposed CIA drone assassination. The emails that are at the heart of the FBI’s criminal investigation are 2011 and 2012 messages between U.S. diplomats in Pakistan and their State Department superiors in D.C., in which the officials approved drone strikes. Clinton’s aides forwarded some of these emails to her personal email account, on a private server in her home in suburban New York.
