Ыtudents develop thought-controlled, hands-free computer for the disabled - 0 views

  •  
    The student team, Ori Ossmy, Ofir Tam and Ariel Rozen, developed the prototype application for their bachelor's degree project under the supervision BGU Prof. Mark Last, Dr. Rami Puzis, Prof. Yuval Lovitz and Dr. Lior Rokah. As part of a recent demonstration, a student composed and sent a hands-free e-mail using only thought combined with the adaptive hardware. The students and BGU team plan to continue research working with the disabled.

NSA reportedly targeted as many as 122 world leaders for surveillance | The Verge - 0 views

  • The documents, leaked to the publications by Edward Snowden, contain a list of 11 world leaders that have been targeted by a system known as Nymrod — however the document implies the actual number targeted was 122. Nymrod is reportedly a system designed to automatically extract citations ("cites") out of a multiplicity of sources, including voice and computer communications. German Chancellor Angela Merkel is listed by name, as are more obvious targets like Syrian president Bashar Asad and former Ukranian prime minister Yulia Tymoshenko. Various leaders apparently have "cites" automatically added to to a "Target Knowledge Database."

Cambridge team breaks superconductor world record | University of Cambridge - 0 views

  • three tonnes of force inside a golf ball-sized sample of material that is normally as brittle as fine china.
  • Superconductors are materials that carry electrical current with little or no resistance when cooled below a certain temperature. While conventional superconductors need to be cooled close to absolute zero (zero degrees on the Kelvin scale, or –273 °C) before they superconduct, high temperature superconductors do so above the boiling point of liquid nitrogen (–196 °C), which makes them relatively easy to cool and cheaper to operate.
  • Superconductors are currently used in scientific and medical applications, such as MRI scanners, and in the future could be used to protect the national grid and increase energy efficiency, due to the amount of electrical current they can carry without losing energy.

Boston Police Used Facial Recognition Software To Grab Photos Of Every Person Attending... - 0 views

  • Ultimately, taking several thousand photos with dozens of surveillance cameras is no greater a violation of privacy than a single photographer taking shots of crowd members. The problem here is the cover-up and the carelessness with which the gathered data was (and is) handled.
  • law enforcement automatically assumes a maximum of secrecy in order to "protect" its investigative techniques
  • The city claims it's not interested in pursuing this sort of surveillance at the moment, finding it to be lacking in "practical value." But it definitely is interested in all the aspects listed above, just not this particular iteration. It also claims it has no policies on hand governing the use of "situational awareness software," but only because it's not currently using any. Anyone want to take bets that the eventual roll out of situational awareness software will be far in advance of any guidance or policies?

Why Scientists Want To Throw Lawn Darts At Mars | Popular Science - 0 views

  • Mars almost definitely has water below its surface, and it’s possible that it might have life there too -- buried deep in the soil, where it’s protected from dryness, radiation and temperature extremes. Unfortunately, NASA doesn’t seem too interested in looking for it, preferring to look for "conditions" that might support life instead. But a group of aerospace and robotics engineers -- many of whom work for NASA, and one of whom even operates the Curiosity rover -- think NASA should be going with a more direct approach, and they're taking matters into their own hands.

Dotcom Faces Jail Following Application to Revoke Bail | TorrentFreak - 0 views

  • a bail revocation application is underway which could put back behind bars as early as next week.
  • Last week it was revealed that his New Zealand legal team had backed out of their arrangement to defend the Megaupload founder.
  • A full report on developments isn’t possible due to a news blackout, but Crown Prosecutor Christine Gordon told the Court that an application had been made to have Dotcom’s bail revoked after an apparent breach of conditions.
  • ...3 more annotations...
  • In the meantime, apparently considering him a flight risk, Judge Nevin Dawson has taken the decision to clamp down on Dotcom’s movements ahead of next week’s hearing.
  • banning him from using his helicopter, Dotcom is forbidden from using boats and undertaking any travel whatsoever by sea. He must stay within 80km (50 miles) of his home and report to police every single day, rather than his previous weekly check-ins.
  • One interested firm said it would need 120 days just to look over the case to see they can help, a serious problem when the extradition hearing is scheduled for February and has taken 18 months to prepare. Today the Crown said it was prepared to give Dotcom an extra month by postponing the hearing until March, but that was overruled by the Judge who said that it would now take place in early June.

Self-repairing software tackles malware -- ScienceDaily - 0 views

  • Unlike a normal virus scanner on consumer PCs that compares a catalog of known viruses to something that has infected the computer, A3 can detect new, unknown viruses or malware automatically by sensing that something is occurring in the computer's operation that is not correct. It then can stop the virus, approximate a repair for the damaged software code, and then learn to never let that bug enter the machine again.
  • To test A3's effectiveness, the team from the U and Raytheon BBN used the infamous software bug called Shellshock for a demonstration to DARPA officials in Jacksonville, Florida, in September. A3 discovered the Shellshock attack on a Web server and repaired the damage in four minutes, Eide says. The team also tested A3 successfully on another half-dozen pieces of malware.
