In the wake of Angela “ Big Ang ” Raiola ‘s death, Mob Wives has continued on —and with it, the never-ending drama between Drita D’avanzo and Karen Gravano . During the series finale on March 9, the woman had one final on-screen battle, only to... “I think if we weren’t on a show, it would be settled in real life,” their costar Brittany Fogarty told RadarOnline. “I think that you keep seeing the drama between Drita and Karen and there’s these fights, but they’re never really fights. “We have this entire crew around us when this fight is happening, and there’s security holding us down and separating us and holding us apart from each other,” she explained. “So in real life, I think Drita would have beat the s*** out of her already.

Most office drones have had to deal with a job that requires them to keep changing their passwords like clockwork, maybe every six months or so. The longstanding IT security practice is based on the idea that flushing out old passwords will cut... "Unless there is reason to believe a password has been compromised or shared, requiring regular password changes may actually do more harm than good in some cases," Cranor wrote Wednesday in a blog post entitled "Time to rethink mandatory password... [ These are the worst passwords of 2015 ]. That's because forcing people to keep changing their passwords can result in workers coming up with, well, bad passwords. It found that users who felt the institution's password policy was annoying came up with passwords that were 46 percent more likely to be guessed than those who supported frequent password changes.

Fast Radio Burst Source Linked to Extreme Magnetic Environment

Using the Arecibo Observatory in Puerto Rico and the Green Bank Telescope in West Virginia, astronomers have gained new insight into the extreme home of a mysterious source of so-called fast radio bursts (FRB). According to the team, radio waves from the recently-discovered repeating FRB, named FRB 121102, are 100% linearly polarized, indicating that they come from an extragalactic source embedded in a strong magnetic field, like that around a massive black hole at the center of a galaxy.The...

Fast radio bursts: A mystery unfolds

Artist’s concept of radio waves from a fast radio burst, being observed by the Green Bank Telescope in West Virginia.Astronomers reported today (January 10, 2018) at the winter meeting of the American Astronomical Society (AAS) in Washington, D.C. on their recent studies of a mysterious source of fast radio bursts – three billion light-years away – known as FRB 121102. They said the source of the bursts must be:… in an astonishingly extreme and unusual environment. This discovery suggests...

FRB 121101: Have Scientists Solved the Mystery of Repeating Radio Signals From Deep Space?

Billions of light-years away, short, sharp radio signals ripple through deep space. Lasting only a fraction of a second, most play out alone. Just one of these fast radio bursts has been found to flash again and again: FRB 121102. Now, scientists might have figured out the physical source of this mysterious extragalactic beep.Published in Nature, results show the signals might emanate from a neutron star in an extreme environment of "unprecedented” power. It could be sitting near a...
