Submission + - MRIs show our brains shutting down when we see security prompts (arstechnica.com)

michelcultivo writes: In a paper scheduled to be presented next month at the Association for Computing Machinery's CHI 2015 conference, researchers will present data that maps regions of the brain responsible for visual processing. The MRI images show a "precipitous drop" in visual processing after even one repeated exposure to a standard security warning and a "large overall drop" after 13 of them. Previously, such warning fatigue has been observed only indirectly, such as one study finding that only 14 percent of participants recognized content changes to confirmation dialog boxes or another that recorded users clicking through one-half of all SSL warnings in less than two seconds.

Submission + - Apple confirms no current plans to bring Siri to o (appleinsider.com)

syngularyx writes: Apple's engineering unit has reportedly confirmed that the company currently has "no plans" to support its Siri personal assistant feature on older devices, according to a person familiar with the matter.

AppleInsider obtained on Tuesday an email, allegedly from Apple in response to a bug report, with the company stating its plans to keep Siri and iPhone 4S exclusive for the time being.

"Engineering has provided the following feedback regarding this issue: Siri only works with iPhone 4S and we currently have no plans to support older devices," the email read.

Apple unveiled Siri last month at its iPhone 4S event. The voice recognition personal assistant is based off technology the company acquired in 2010. The feature quickly made waves because of its advanced natural language processing abilities.

But, the service is currently in beta, a fact that users were reminded of last week when it experienced widespread outages.


Submission + - IBM creates learning, brain-like synaptic CPU (extremetech.com)

MrSeb writes: "After six years, significant investment by DARPA and IBM, and millions of man hours, researchers at IBM have created two silicon chips that are fundamentally brain-like in their operation. Built using IBM’s 45nm process, these chips are still constructed out of transistors, but they’re organized into a novel arrangement that mimics the neurons and synapses of animal brains. Both of the chips have 256 digital neurons that operate at 10MHz, and standard chip features like memory, communication controllers, and so on. One of the chips has 262,144 human-programmable synapses — but the other chip has 65,356 learning synapses, which are connected in a crossbar array for a total of almost 17 million different connections."

Submission + - Ask slashdot: security education for PMs

Suferick writes: I am putting together a security education program aimed at project managers. Some of them are technical and some not; they work in an environment that is very security conscious but sometimes have very little clue about security. What are the most important topics I should cover?
