Submission + - Mystery Intergalactic Radio Bursts Detected (discovery.com)

astroengine writes: Astronomers were on a celestial fishing expedition for pulsing neutron stars and other radio bursts when they found something unexpected in archived sky sweeps conducted by the Parkes radio telescope in New South Wales, Australia. The powerful signal, which lasted for just milliseconds, could have been a fluke, but then the team found three more equally energetic transient flashes all far removed from the galactic plane and coming from different points in the sky. Astronomers are at a loss to explain what these flashes are — they could be a common astrophysical phenomenon that has only just been detected as our radio antennae have become sensitive enough, or they could be very rare and totally new phenomenon that, so far, defies explanation.

Submission + - Discrete Log Problem Breakthrough Threatens Crypto

tbonefrog writes: Cryptographic ground truth is changing fast. In February Antoine Joux produced a new record subexponential discrete logarithm algorithm running at L(1/4) speed and beating the long-standing L(1/3) mark. On June 20 a quasipolynomial algorithm was announced at the Workshop on Number-Theoretic Algorithms for Asymmetric Cryptology in France, and explained by Stephen Galbraith

Discrete logarithm and factoring are different problems but progress on one tends to lead to progress in the other. Get a paper bank statement mailed to you each month, order some paper checks, and buy stamps and envelopes for paying your bills via snail mail.

Submission + - Harlan: A language that simplifies GPU programming released (paritynews.com) 1

hypnosec writes: Harlan – a declarative programming language that simplifies development of applications running on GPU has been released by a researcher at Indian University. Erik Holk released his work publicly after working on it for two years. Harlan’s syntax is based on Scheme – a dialect of LISP programming language. The language aims to help developers make productive and efficient use of GPUs by enabling them to carry out their actual work while it takes care of the routine GPU programming tasks. The language has been designed to support GPU programming and it works much closer to the hardware.

sorry but the point, I think, is for microsoft not only to "sting" the servers and finding the infected computers.... what are they doing in order to prevent those computers to become infected? I think the problems should be addressed from several parts.. stinging the command and control will only relief for some time... in a few days or weeks, another virus or trojan will infect pcs again and so on... what is Microsoft doing in order to avoid PCs to be infected.

itwbennett writes: "When you sign up for online dating, there's a certain amount of information you expect to give up, like whether or not your weight is proportional to your height. But you probably don't expect that your profile will remain online long after you stop subscribing to the service. In some cases your photo can be found even after being deleted from the index, according to the electronic frontier foundation (EFF), which identified six major security weaknesses in online dating sites."

Submission + - RIP Compiz (techrepublic.com)

vst writes: From the article: "This is not 100% confirmed, but the news that Fedora is dropping Compiz from release 17 can only mean one thing — Compiz is dead. Gentoo, openSUSE, GNOME, and a list of others had already dropped Compiz, leaving only one distribution holding onto the compositing software — Ubuntu."

Submission + - Alaskan tests to use waste CO2 to flush out natura (nature.com)

ananyo writes: This month, scientists will test a new way to extract methane from beneath the frozen soil of Alaska: they will use waste carbon dioxide from conventional wells to force out the desired natural gas.

The pilot experiment will explore the possibility of ‘mining’ from gas hydrates: cages of water ice that hold molecules of methane. Such hydrates exist under the sea floor and in sandstone deep beneath the Arctic tundra, holding potentially vast reserves of natural gas. But getting the gas out is tricky and expensive.

The test is to be run by the US Department of Energy (DOE), in conjunction with ConocoPhillips, an oil company based in Houston, Texas, and the Japan Oil, Gas and Metals National Corporation. The researchers will pump CO2 down a well in Prudhoe Bay, Alaska, into a hydrate deposit. If all goes as planned, the CO2 molecules will exchange with the methane in the hydrates, leaving the water crystals intact and freeing the methane to flow up the well.

Submission + - Dart Does Physics - Just To Prove It Can! (i-programmer.info)

mikejuk writes: One of the difficulties in getting a new computer language accepted by a wider audience is that there is doubt that it is real. Is it a toy language that just proves a concept or can it do real work?
In the case of Dart, which is Google's replacement for JavaScript, the development is speeding ahead at a rate that is impressive but worrying. To prove that Dart is already a language that can be used, we now have a port of the well known 2D physics engine Box2D, the one Angry Birds uses, to Dart. Take a look at the demo website http://dartbox2d.googlecode.com/git/demos.html and be impressed once again at what HTML5 and JavaScript can do but take note that at the moment it only seems to work under Chrome.

The system, shown at the CES show, takes a photo of any phone or other gadget put in its tray, and provides a data cable (for every kind of phone?) to check it is working.

Submission + - Femtocell maker Picochip bought by Mindspeed for & (techworld.com)

sweetpea86 writes: UK-based femtocell maker Picochip has been snapped up by Mindspeed Technologies, a supplier of semiconductor solutions for network infrastructure applications, for $51.8 million (£33.5m). The two companies intend to merge their respective 3G and 4G technologies and lead the industry’s move toward fixed/mobile broadband convergence.

Picochip currently provides around 70 percent of the chips used to make femtocells, but has had difficulty converting its success in 3G/HSPA into LTE growth. Femtocells are used to beef up 3G network strength,and have been touted as a way to solve the problem of 3G ‘not-spots’, as well as easing strain on mobile networks during London's Olympic Games.
