Submission + - OpenSSL 1.0.2 Released (marc.info)

kthreadd writes: The OpenSSL project has released its second feature release of the OpenSSL 1.0 series, version 1.0.2 which is ABI compatible with the 1.0.0 and 1.0.1 series. Major new features in this release include Suite B support for TLS 1.2 and DTLS 1.2 and support for DTLS 1.2. selection. Other major changes include TLS automatic EC curve selection, an API to set TLS supported signature algorithms and curves, the SSL_CONF configuration API, support for TLS Brainpool, support for ALPN and support for CMS support for RSA-PSS, RSA-OAEP, ECDH and X9.42 DH.

Submission + - Finding ET – we're gonna need a bigger dish (newscientist.com) 1

Z00L00K writes: The hunt for alien civilisations may need a rethink. A new paper argues that the signals we're listening for might not be the ones ET would choose.

Historically, SETI – the search for extraterrestrial intelligence – involves scanning the sky for radio signals that another civilization is deliberately sending. The simplest would be a constant blast in all directions, but in a narrow range of frequencies, similar to early radio broadcasts – like a constant hum that would tell a listener it is artificial. From light years away, we would not be able to get any other information – all we would be able to tell from Earth is that a signal was there and where it was coming from, not what it says.

Submission + - Americans Support Mandatory Labeling of Food That Contains DNA

HughPickens.com writes: Jennifer Abel writes at the LA times that according to a recent survey over 80% of Americans says they support “mandatory labels on foods containing DNA,” roughly the same number that support the mandatory labeling of GMO foods “produced with genetic engineering.” Ilya Somin, writing about the survey at the Washington Post, suggested that a mandatory label for foods containing DNA might sound like this: "WARNING: This product contains deoxyribonucleic acid (DNA). The Surgeon General has determined that DNA is linked to a variety of diseases in both animals and humans. In some configurations, it is a risk factor for cancer and heart disease. Pregnant women are at very high risk of passing on DNA to their children."

The report echoes a well-known joke/prank wherein people discuss the dangers of the chemical “dihydrogen monoxide" also known as hydrogen oxide and hydrogen hydroxide. Search online for information about dihydrogen monoxide, and you'll find a long list of scary-sounding and absolutely true warnings about it: the nuclear power industry uses enormous quantities of it every year. Dihydrogen monoxide is used in the production of many highly toxic pesticides, and chemical weapons banned by the Geneva Conventions. Dihydrogen monoxide is found in all tumors removed from cancer patients, and is guaranteed fatal to humans in large quantities and even small quantities can kill you, if it enters your respiratory system. In 2006, in Louisville, Kentucky, David Karem, executive director of the Waterfront Development Corporation, a public body that operates Waterfront Park, wished to deter bathers from using a large public fountain. "Counting on a lack of understanding about water's chemical makeup," he arranged for signs reading: "DANGER! – WATER CONTAINS HIGH LEVELS OF HYDROGEN – KEEP OUT" to be posted on the fountain at public expense

Submission + - Bjarne Stroustrup Awarded Dahl-Nygaard Prize (i-programmer.info)

mikejuk writes: Bjarne Stroustrup, the creator of C++, is the 2015 recipient of the Senior Dahl-Nygaard Prize, considered the most prestigious prize in object-oriented computer science. Established in 2005 it honors the pioneering work on object-orientation of Ole-Johan Dahl and Kristen Nygaard who, designed Simula, the original object-oriented language and are remembered as "colorful characters".
To be eligible for the senior prize an individual must have made a
"significant long-term contribution to the field of Object-Orientation"
and this year it goes to Bjarne Stoustrup for the design, implementation and evolution of the C++ programming language. You can't argue with that.

Submission + - Twitter moves to curb Instagram links

Hammeh writes: According to a report on Mashable, Twitter have sent out messages to some of their high profile users prompting them to share images using Twitter's own service rather than Instagram links. The news comes 2 years since Instagram pulled support for Twitter cards and has been part of the continuing battle between the two social networks. With Instagram now having overtaken Twitter in terms of users, this may be a move to try and use high profile users to show off Twitter's own image and content tools.

Submission + - Ask Slashdot: GPU of choice for OpenCL on Linux?

Bram Stolk writes: So, I am running GNU/Linux on a modern Haswell CPU, with an old Radeon HD5xxx from 2009. I'm pretty happy with the open source Gallium driver for 3D acceleration.

But now I want to do some GPGPU development using OpenCL on this box, and the old GPU will no longer cut it. What do my fellow technophiles from slashdot recommend as a replacement GPU? Go nVidia, go AMD, or just use the integrated Intel GPU instead? Bonus points for open sourced solutions. Performance not really important, but OpenCL driver maturity is.

Comment Saudi copes with low prices for at least 8 yrs (Score 5, Interesting) 141

From http://www.bbc.com/news/busine...

"Saudi Arabia can cope with low oil prices for "at least eight years", Saudi Arabia's minister of petroleum's former senior adviser has told the BBC. Mohammed al-Sabban said the country's policy was to defend its current market share by enduring low prices. "You need to allow prices to go as low as possible in order to see those marginal producers move out of the market," he said."

Eight happy years!

"The dramatic fall in the oil price will spur the UK economy to grow faster than had been predicted this year, according to influential forecaster the EY ITEM Club."

Comment Re:And what about net trolls? (Score 1) 42

That is an issue overcome by Wikipedia quite rapidly. One or a few trolls per hundred contributors are rapidly swamped out. Look at Slashdot. ;) My suggestion would be that the rather collaborate formally with Wikipedia, and tap their infrastructure, to get it going for real. I realize this may feel awkward and may hamper enthusiasm and funding opportunities if proposed the wrong way. Yet, it would give the idea a stronger start if they are more interested in their idea than in funding. Questions related to Strontium would be next the to the Wikipedia of Strontium, etc.

Any belief in the supernatural is begging for a disaster in the long run, be it Hinduism, Judaism, Animatrix, Obelix, Jesus, whatever. The violence you see in the Bible, Asterix and in the Wachowsky Epic is largely irrelevant. It is the belief as such which is the dangerous feed for the alienated.

Comment Shi's Law, Gustafsson's Law, Amdahls Law (Score 3, Insightful) 449

Shi's Law

http://slashdot.org/comments.p...

"Researchers in the parallel processing community have been using Amdahl's Law and Gustafson's Law to obtain estimated speedups as measures of parallel program potential. In 1967, Amdahl's Law was used as an argument against massively parallel processing. Since 1988 Gustafson's Law has been used to justify massively parallel processing (MPP). Interestingly, a careful analysis reveals that these two laws are in fact identical. The well publicized arguments were resulted from misunderstandings of the nature of both laws.

This paper establishes the mathematical equivalence between Amdahl's Law and Gustafson's Law. We also focus on an often neglected prerequisite to applying the Amdahl's Law: the serial and parallel programs must compute the same total number of steps for the same input. There is a class of commonly used algorithms for which this prerequisite is hard to satisfy. For these algorithms, the law can be abused. A simple rule is provided to identify these algorithms.

We conclude that the use of the "serial percentage" concept in parallel performance evaluation is misleading. It has caused nearly three decades of confusion in the parallel processing community. This confusion disappears when processing times are used in the formulations. Therefore, we suggest that time-based formulations would be the most appropriate for parallel performance evaluation."
