“like-sign dimuon charge asymmetry…in disagreement with the prediction of the standard model by 3.2 standard deviations”

OK, now VMs are totally safe! No need to worry about escape attacks or rootkits…but seriously, it’s good that not everyone takes hypervisor security for granted.

“there is now a significant body of work showing how to break conventional quantum cryptography systems based on various practical weaknesses in the way they are set up…while the known loopholes can be papered over, it’s the unknown ones that represent threats in the future…[researchers have shown that it's easy] with a little malicious intent to bend the assumptions behind perfect quantum cryptography.”

Principles of Robust Timing Over the Internet

“[An IPv4 address space] black market already exists, albeit on a small scale…[currently] IPv4 addresses are still relatively easy to get…[some believe] that regional registries such as ARIN should head off a potentially deleterious black market by creating a “white market” with established rules for trading IPv4 addresses at market-established costs…But the opportunity to cleanly switch from IPv4 to IPv6 passed many years ago. The current transition strategy, called “dual stack,” requires businesses to remain connected to both IPv4 and IPv6 networks until most of the Internet gets to “the other side” — a process expected to take at least five years.”

“Frosted windows may never be private again”

“a fundamental limit to the level of privacy that is possible when social networks are mined for recommendations”

“The 605-page [NSA IAD] PDF document reads like a listing of the pros and cons for a huge array of defensive and counterintelligence approaches and technologies that an entity might adopt in defending its networks…[one] section delves into the challenges of attributing the true origin(s) of a computer network attack”
