Submission + - ask slashdot: HTML5 privacy and security countermeasures?

An anonymous reader writes: From time to time, I see articles about how HTML 5 can do all sorts of things that used to require scripting. See for example:

Does anybody know of any countermeasures I could take? Is there anything like NOSCRIPT available for shutting down either all of or else just the unwanted aspects of HTML5 ?

Submission + - MH370: Chinese patrol ship detects pulse signal ( 1

mdsolar writes: A Chinese search ship has detected an electronic pulse in an area of the southern Indian Ocean where it is believed the missing Malaysian Airlines plane crashed, state media has announced.

"Chinese patrol ship Haixun 01 searching for flight MH370 discovered a pulse signal with a frequency of 37.5kHz per second in south Indian Ocean waters Saturday," the official news agency, Xinhua, said.

The single-sentence story is the first potentially positive sign in the race against time to find the Malaysian aircraft's black box. But there is as yet no indication of whether the pulse is in fact connected to the plane, and no wreckage has been found in the area despite a massive international hunt.

Submission + - How to easily turn your Chromebook into a Kiosk (

sfcrazy writes: The last ChromeOS update now makes it amazingly simple to enable Kiosk Mode on your ChromeOS device. Previously, this was a more manual affair, but times are a changing. Rather than comb through policies yourself, there is now a method to make the process much easier. This mode is squarely aimed at shops and users who wish to present a single app to a set of users, restricting use of ChromeOS only to that application. Also, when in this mode, ChromeOS disables key features such as the login screen, screen locking, among other multi-user features.

Submission + - Outrage and the gender gap in IT (

sandbagger writes: A few years ago Slashdot made its website pink on April 1 as a gag about attracting women to IT careers. A recent Information Week article says that biusiness is booming for pundits who get their clicks bemoaning the existential danger of gender imbalances in high tech. But guess what? It's irrational BS.

Submission + - Gmail's 'Unsubscribe' Tool Comes Out Of the Weeds (

itwbennett writes: Starting this week, a new, clearly marked 'unsubscribe' link will appear at the top of the header field in marketers' emails. Previously only appearing for a small percentage of users, the feature will now be made available for most promotional messages with unsubscribe options, Google said on Thursday. Email recipients do not need to take action for the links to appear.

Submission + - Researchers Discover Why Evolution Was Initially Stagnant (

mphall21 writes: Researchers discovered that low oxygen levels were to blame for the evolutionary stagnation of early life. Tasmanian researchers analyzed sea floor rocks and found the early oceans lacked the amount of oxygen and biologically-important elements to support more complex life forms.

“We’ve looked at thousands of samples of the mineral pyrite in rocks that formed in the ancient oceans,” said Geologist Professor Ross Large. “By measuring the levels of certain trace elements in the pyrite... we’ve found that we can tell an accurate story about how much oxygen and nutrients were around billions of years ago.”

Large says his team was trying to understand how mineral deposits form by looking at the oxygen levels of the ancient oceans. However, his team found the technology to look for minerals also told them much about the evolution of life.

The findings will be published in the Earth and Planetary Science Letters' March issue.

Submission + - UK Surgeon Implants a 3-D Printed Pelvis

An anonymous reader writes: Neat story out of Britain, with a strange delay in its circulation, but good news about long-term success for the patient involved, and for others who might benefit from similar procedures: three years ago, surgeon Craig Gerrand (he's got a cool handle on Twitter, too) successfully printed and implanted an artificial pelvis (actually, about half of one) into a patient suffering from a rare form of cancer. Other techniques were ruled out, because the patient would be losing so much bone. So, after careful scanning, additive printing with titanium was used to create the replacement: 'In order to create the 3-D printed pelvis, the surgeons took scans of the man’s pelvis to take exact measurements of how much 3-D printed bone needed to be produced and passed it along to Stanmore Implants. The company used the scans to create a titanium 3-D replacement, by fusing layers of titanium together and then coating it with a mineral that would allow the remaining bone cells to attach.'

Submission + - SPAM: New blood cells fight brain inflammation

Benzainload895 writes: Hyperactivity of our immune system can cause a state of chronic inflammation. If chronic, the inflammation will affect our body and result in disease. In the devastating disease multiple sclerosis, hyperactivity of immune cells called T-cells induce chronic inflammation and degeneration of the brain. Researchers at BRIC, the University of Copenhagen, have identified a new type of regulatory blood cells that can combat such hyperactive T-cells in blood from patients with multiple sclerosis. By stimulating the regulatory blood cells, the researchers significantly decreased the level of brain inflammation and disease in a biological model.

Comment Teaching is a social "science" (Score 5, Insightful) 264

Teaching as a discipline is one of many social sciences,
but since it's not a true science, there is no pressure to
create quantitative measures for any of their components.
No rigor, no quant, and you leave it up to individual motivations
as the driving forces.
Result, as the article states, easier classes mean higher grades.
Higher grades means better teacher evaluations.
Better evaluations means easier job and more money.
Result - grade inflation.
It seems obvious now, so we shouldn't be surprised.
The real question should be this: when can we expect the bubble to burst?

Comment Brilliant hack! (Score 5, Interesting) 163

There was a time, before we all lost our minds to Pong, Asteroids and Zelda (yes, I go way back) where we also spent time taking our world apart and figuring out how to make it better.

Oona rocks! She should be rewarded somehow.

BTW - the end of the article finally explains how a megahertz signal found its way onto the audio track.
