Dubbed WordHound, the freely available tool scours press releases, white papers, and Twitter accounts belonging to companies or sites that have recently suffered security breaches. The software then generates a list of commonly found words or phrases that attackers can use when trying to convert cryptographic hashes from compromised password databases into the corresponding plaintext passcodes. The tool, devised by security consultant Matthew Marx, was unveiled Wednesday at Passwords 14 conference in Las Vegas.
”People are influenced greatly by their environment when choosing a password,” Marx, who works for consultancy , told Ars. “It could be a work environment, their personal life, or the sport teams they like. I wanted to create a tool that leveraged this human vulnerability.”
What we perceive as the big bang, physicists at the Perimeter Institure argue, could be the three-dimensional “mirage” of a collapsing star in a universe profoundly different than our own. Conventional understanding holds that the big bang began with a singularity – an unfathomably hot and dense phenomenon of spacetime where the standard laws of physics break down. Singularities are bizarre, and our understanding of them is limited.
Our universe may have emerged from a black hole in a higher-dimensional universe, proposed a trio of Perimeter Institute&t=h) researchers in the cover story of the latest Scientific American. “Cosmology’s greatest challenge is understanding the big bang itself,” write Perimeter Institute faculty member, Niayesh Afshordi.
The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it?
Three Perimeter Institute researchers have a new idea about what might have come before the big bang. It’s a bit perplexing, but it is grounded in sound mathematics, testable, and enticing enough to earn the cover story in Scientific American, called “The Black Hole at the Beginning of Time.”
Many of today’s technological innovations from the iPhone to electric motors for hybrid cars require the use of materials—elements—that are scarce or difficult to obtain. As demand for these devices grows, the problem of dwindling critical element supplies must be addressed. That’s the conclusion of a white paper written by eminent scientists. The product of the 5th Chemical Sciences and Society Summit (CS3), the white paper recommends focusing research on finding alternative materials and new approaches to technology development in order to prevent these elements from disappearing.
The white paper, “The Efficient Use of Elements,” is a topic of discussion at this year’s the 248th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society. The meeting features nearly 12,000 reports on new advances in science and other topics. It is being held here through Thursday.
As many have noted, Ferguson, Missouri, currently looks like a war zone. And its police—kitted out with Marine-issue camouflage and military-grade body armor, toting short-barreled assault rifles, and rolling around in armored vehicles—are indistinguishable from soldiers.
America has been quietly arming its police for battle since the early 1990s.
Faced with a bloated military and what it perceived as a worsening drug crisis, the 101st Congress in 1990 enacted the National Defense Authorization Act. Section 1208 of the NDAA allowed the Secretary of Defense to “transfer to Federal and State agencies personal property of the Department of Defense, including small arms and ammunition, that the Secretary determines is— (A) suitable for use by such agencies in counter-drug activities; and (B) excess to the needs of the Department of Defense.” It was called the 1208 Program. In 1996, Congress replaced Section 1208 with Section 1033.
