Submission + - It's Time To Split Linux In Two 7

snydeq writes: Desktop workloads and server workloads have different needs, and it's high time Linux consider a split to more adequately address them, writes Deep End's Paul Venezia. 'You can take a Linux installation of nearly any distribution and turn it into a server, then back into a workstation by installing and uninstalling various packages. The OS core remains the same, and the stability and performance will be roughly the same, assuming you tune they system along the way. Those two workloads are very different, however, and as computing power continues to increase, the workloads are diverging even more. Maybe it's time Linux is split in two. I suggested this possibility last week when discussing systemd (or that FreeBSD could see higher server adoption), but it's more than systemd coming into play here. It's from the bootloader all the way up. The more we see Linux distributions trying to offer chimera-like operating systems that can be a server or a desktop at a whim, the more we tend to see the dilution of both. You can run stock Debian Jessie on your laptop or on a 64-way server. Does it not make sense to concentrate all efforts on one or the other?'

Submission + - Bill Gates Want to Remake the Way History is Taught. Should We Let Him?

theodp writes: With his Big History Project, the NY Times' Andrew Ross Sorkin reports that Bill Gates wants to remake the way history is taught (intro video). Last month, the Univ. of California system announced that a version of the Big History Project course could be counted in place of a more traditional World History class, paving the way for the state's 1,300 high schools to offer it. Still, not everyone's keen on the idea. "Is this Bill Gates's history?" asks NYU's Diane Ravitch. "And should it be labeled 'Bill Gates's History'? Because Bill Gates's history would be very different from somebody else's who wasn't worth $50-60 billion." Of the opposition to Gates, Scott L. Thomas of Claremont Graduate University explains, 'Frankly, in the eyes of the critics, he's really not an expert. He just happens to be a guy that watched a DVD and thought it was a good idea and had a bunch of money to fund it."

Submission + - IT Jobs Take Summer Swan Dive 1

snydeq writes: The IT job hiring bump earlier this year wasn't sustained in July and August, when numbers slumped considerably, InfoWorld reports. 'So much for the light at the end of the IT jobs tunnel. According to job data released by the Bureau of Labor Statistics, as analyzed by Janco Associates, the IT professional job market has all but lost the head of steam it built up earlier this year. A mere 3,400 IT jobs were added in August, down from 4,600 added for July and way down from the 13,800 added in April of this year. Overall, IT hiring in 2014 got off to a weak start, then surged, only to stumble again.' Anybody out there finding the IT job market discouraging of late and care to share their experiences?

Submission + - Newly Discovered Asteroid Passing Within Geostationary Orbit Sunday 1

theshowmecanuck writes: A newly found asteroid the size of a house will give earth a close flyby this weekend. It will pass just below satellites in geostationary orbit, and above New Zealand around 14:18 EDT / 18:18 GMT / 06:18 NZST this coming Sunday (Monday morning in NZ).

"Asteroid 2014 RC was initially discovered on the night of August 31 by the Catalina Sky Survey near Tucson, Arizona, and independently detected the next night by the Pan-STARRS 1 telescope, located on the summit of Haleakal on Maui, Hawaii," NASA officials said in a statement."

Submission + - Lifeform out of the "Tree of Life" found off the coast of Australia (bbc.com)

Taco Cowboy writes: A mushroom-shaped sea animal discovered off the Tasmanian coast back in 1986 has defied classification in the tree of life

A team of scientists at the University of Copenhagen says the tiny organism does not fit into any of the known subdivisions of the animal kingdom. The organisms, which were originally collected in 1986, are described in the academic journal Plos One. Such a situation has occurred only a handful of times in the last 100 years

The authors of the paper recognise two new species of mushroom-shaped animal: Dendrogramma enigmatica and Dendrogramma discoides. Measuring only a few millimetres in size, the animals consist of a flattened disc and a stalk with a mouth on the end. The authors of the article note several similarities with the bizarre and enigmatic soft-bodied life forms that lived between 635 and 540 million years ago — the span of Earth history known as the Ediacaran Period. Those organisms, too, have proven difficult to categorise and some researchers have even suggested they were failed experiments in multi-cellular life

During a scientific cruise in 1986, scientists collected organisms at water depths of 400m and 1,000m on the south-east Australian continental slope, near Tasmania. But the two types of mushroom-shaped organisms were recognised only recently, after sorting of the bulk samples collected during the expedition. "Finding something like this is extremely rare, it's maybe only happened about four times in the last 100 years," said co-author Jorgen Olesen from the University of Copenhagen

The new organisms are multicellular but mostly non-symmetrical, with a dense layer of gelatinous material between the outer skin cell and inner stomach cell layers. The researchers did find some similarities to other animal groupings, such as the Cnidaria — the phylum that comprises corals and jellyfish — and the Ctenophora, which includes the marine organisms known as comb jellies. But the new organisms did not fulfil all the criteria required for inclusion in either of those categories. Dr Olesen said the new animals could either be a very early branch on the tree of life, or be intermediate between two different animal phyla

One way to resolve the question surrounding Dendrogramma's affinities would be to examine its DNA, but new specimens will need to be found. The original samples were first preserved in formaldehyde and later transferred to 80% alcohol, a mode of treatment that prevents analysis of genetic material. Accordingly, the team's paper in Plos One calls for researchers around the world to keep an eye out for other examples. "We published this paper in part as a cry for help," said Dr Olesen. "There might be somebody out there who can help place it"

PLAR writes: The team assigned to pump potentially sensitive information out of Home Depot employees during live cold calls during this year's Social Engineering Capture the Flag competition at the DEF CON 22 hacker conference won the overall contest, which targeted major US retailers. While the contest was obviously unrelated to this week's revelation of a possible breach at the home improvement chain, it's an interesting look at the retail industry's wave of security woes.

Submission + - The Passenger Pigeon: A Century of Extinction 1

An anonymous reader writes: On September 1, 1914, Martha, the last passenger pigeon was found dead in her aviary at the Cincinnati Zoo. When the first European settlers arrived in North America at least one of every four birds on the continent was a passenger pigeon, making them the most numerous birds in North America, and perhaps in the world. From the article: "But extinction apparently doesn’t ring with the finality it used to. Researchers are working to 'de-extinct' the bird. They got their hands on some of the 1,500 or so known passenger pigeon specimens and are hoping to resurrect the species through some Jurassic Park-like genetic engineering. Instead of using frog DNA to fill out the missing parts of a dinosaur’s genetic code as in Michael Crichton’s story, the real-life 'bring-back-the-passenger pigeon' researchers are using the bird’s closest relative, the band-tailed pigeon.

Submission + - Battle of the heavy lift rockets

schwit1 writes: Check out this very detailed and informative look at unstated competiton between NASA’s SLS rocket and SpaceX’s heavy lift rocket plans that are even more powerful than the Falcon Heavy.

Key quote: "It is clear SpaceX envisions a rocket far more powerful than even the fully evolved Block 2 SLS – a NASA rocket that isn’t set to be launched until the 2030s."

The SpaceX rocket hinges on whether the company can successfully build its new Raptor engine. If they do, they will have their heavy lift rocket in the air and functioning far sooner than NASA, and for far far far less money.

Submission + - Which Is More Scalable, Nuclear Energy Or Wind Energy? (forbes.com) 1

mdsolar writes: Summary: Empirically, wind energy is much more scalable than nuclear energy.

China is the true experiment for maximum scalability of nuclear vs wind. It has a tremendous gap between demand and generation. It can mostly ignore democracy and social license for nuclear. It is building both wind and nuclear as rapidly as possible. It has been on a crash course for both for about the same period of time. It has bypassed most of the regulatory red tape for nuclear.

So how is it doing?

        China turned on just over 16 GW of nameplate capacity of wind generation in 2013 according to the Global Wind Energy Council.

Over the four years of 2010 to 2014, China managed to put 4.7 GW of nuclear into operation at the Qinshan Phase II, Ling Ao Phase II, Ningde, Hongyanhe and Yangjiang plants. This is not their stated plans for nuclear, which had them building almost double this in 2013 alone and around 28 GW by 2015, but the actual plants put into production. The variance between the nuclear roadmap and nuclear reality in China is following the trajectory of nuclear buildout worldwide: delays, cost overruns, and unmet expectations.

Taffykay writes: Science recently scored a simultaneous victory over pollution for both recycling and renewable energy! A team of researchers at MIT has come up with plan to turn old car batteries into durable solar panels. According to Phys.org, the system proposed by a group of MIT professors and published in the journal Energy and Environmental Science uses a fairly new solar cell technology that includes a compound called perovskite, which is nearly on par with traditional silicon-based cells but takes significantly less material to manufacture.

Submission + - Hemp fibres make better supercapacitors than graphene (bbc.co.uk)

biodata writes: BBC News is reporting findings published in the journal ACS Nano by Dr David Mitlin's group from Clarkson University, New York.
"We're making graphene-like materials for a thousandth of the price — and we're doing it with waste."
"The hemp we use is perfectly legal to grow. It has no THC in it at all — so there's no overlap with any recreational activities."
Dr. Mitlin's team took waste hemp stems and recycled the material into supercapacitors with performance as good, or better, than those built from graphene, at a fraction of the raw materials cost.
