Submission + - GCHQ Builds A Raspberry Pi Super Computer Cluster (i-programmer.info)

mikejuk writes: GCHQ, the UK equivalent of the NSA, has created a 66 Raspberry Pi cluster called the Bramble for "educational" purposes. What educational purposes isn't exactly clear but you do associate super computers with spooks and spies. It seems that there was an internal competition to invent something and three, unnamed, GCHQ technologists decided that other Pi clusters were too ad-hoc. They set themselves the target of creating a cluster that could be reproduced as a standard architecture to create a commodity cluster.
The basic unit of the cluster is a set of eight networked Pis, called an "OctaPi" — one thing you have to admit is that the Raspberry Pi name lends itself to silly variations. Each OctaPi can be used standalone or hooked up to make a bigger cluster. In the case of the Bramble a total of eight OctaPis makes the cluster 64 processors strong. In addition there are two head control nodes, which couple the cluster to the outside world. Each head node has one Pi, a wired and WiFi connection, realtime clock, a touch screen and a camera.
This is where the story becomes really interesting. Rather than just adopt a standard cluster application like Hadoop, OctaPi's creators decided to develop their own. After three iterations, the software to manage the cluster is now based on Node.js, Bootstrap and Angular.
So what is it all for?
The press release says that:
"The initial aim for the cluster was as a teaching tool for GCHQ’s software engineering community."
and then goes on to say:
"The ultimate aim is to use the OctaPi concept in schools to help teach efficient and effective programming. Watch this space for more details!"
The second point seems a bit unlikely.
Is it going to be open source?
Given that this is a GCHQ creation it seems unlikely, but we can hope.

PG&E Makes Deal For Solar Power From Space 392

N!NJA writes "California's biggest energy utility announced a deal Monday to purchase 200 megawatts of electricity from a startup company that plans to beam the power down to Earth from outer space, beginning in 2016. Solaren would generate the power using solar panels in Earth orbit and convert it to radio-frequency transmissions that would be beamed down to a receiving station in Fresno, PG&E said. From there, the energy would be converted into electricity and fed into PG&E's power grid."

Should Good Indie Games Be More Expensive? 150

spidweb writes "Indie gaming blog The Bottom Feeder has an article on why independent games should be more expensive. The enforced low prices on XBox Live, Amazon, and iTunes might feel good now, but they'll kill off the variety and depth gamers are hoping indie developers can provide. From the article: 'Every year, life is getting more and more expensive. Insurance. Rent. Food. And, at the same time, games are getting cheaper and cheaper, sometimes as cheap as a dollar, as we engage in a full speed race to the bottom. This is not going to help developers stay in business. This is not how a healthy industry is maintained.'"

Slashdot Keybindings, Dynamic Stories 220

We've been working hard on the new dynamic Slashdot project (logged in users can enable this by enabling the beta index in their user preferences). I just wanted to quickly mention that there are keybindings on the index. The WASD and VI movement keys do stuff that we like, and the faq has the complete list. Also, if you are using Firefox or have Index2 beta enabled, you can click 'More' in the footer at the end of the page to load the next block of stories in-line without a page refresh. We're experimenting now with page sizes to balance load times against the likelihood that you'll click. More features will be coming soon, but the main thing on our agenda now is optimization. The beta index2 is sloooow and that's gotta change. We're aiming for 2 major optimizations this week (CSS Sprites, and removing an old YUI library) that I'm hoping will put the beta page render time into the "Sane" time frame (which, in case you are wondering, is several seconds faster than that "Insane" time frame we're currently seeing).

First Flight of Jet Powered By Algae-Fuel 255

s31523 writes "Today a US airline carrier conducted a 90 minute test flight with one of its engines powered by a 50/50 blend of biofuel and normal aircraft fuel. This was the first flight by a US carrier after other airlines have reported trying similar flights. In February 2008, a Virgin 747 flew from London to Amsterdam partly using a fuel derived from a blend of Brazilian babassu nuts and coconuts. At the end of December, one engine of an Air New Zealand 747 was powered by a 50/50 blend of jatropha plant oil and standard A1 jet fuel."

The State of UK Broadband — Not So Fast 279

Barence writes "The deplorable speed of British broadband connections has been revealed in the latest figures from the Office of National Statistics, which show that 42.3% of broadband connections are slower than 2Mb/sec. More worryingly, the ONS statistics are based on the connection's headline speed, not actual throughput, which means that many more British broadband connections are effectively below the 2Mb/sec barrier. Better still, a separate report issued yesterday by Ofcom revealed that the majority of broadband users had no idea about the speed of their connection anyway."

Rewriting a Software Product After Quitting a Job? 604

hi_caramba_2008 writes "We are a bunch of good friends at a large software company. The product we work on is under-budgeted and over-hyped by the sales drones. The code quality sucks, and management keeps pulling in different direction. Discussing this among ourselves, we talked about leaving the company and rebuilding the code from scratch over a few months. We are not taking any code with us. We are not taking customer lists (we probably will aim at different customers anyway). The code architecture will also be different — hosted vs. stand-alone, different modules and APIs. But at the feature level, we will imitate this product. Can we be sued for IP infringement, theft, or whatever? Are workers allowed to imitate the product they were working on? We know we have to deal with the non-compete clause in our employment contracts, but in our state this clause has been very difficult to enforce. We are more concerned with other IP legal aspects."

Free Online Scientific Repository Hits Milestone 111

ocean_soul writes "Last week the free and open access repository for scientific (mainly physics but also math, computer sciences...) papers arXiv got past 500,000 different papers, not counting older versions of the same article. Especially for physicists, it is the number-one resource for the latest scientific results. Most researchers publish their papers on arXiv before they are published in a 'normal' journal. A famous example is Grisha Perelman, who published his award-winning paper exclusively on arXiv."

A Look At the Warhammer Community 169

Gamasutra is running a story examining the development of the Warhammer Online community since its recent launch. The author explains how the gameplay and rules tend to affect social interaction. GamerDNA has a related piece looking at numbers for actual players involved with Warhammer's launch, and how it's affecting populations in other MMOs. "Getting on the computer to play WAR apparently reminded the WAR fanatics that they had a computer, because overall, their gameplay went up as a whole. They logged in more often to titles like COD4, Oblivion, and even AOC. But the MMO bug bit hard, and logins to LOTRO and EVE more than doubled after the launch of WAR."

Menace of slideware

Submission + - DARPA planning liquid robots

moon_monkey writes: According to New Scientist, Darpa is soliciting proposals for so-called Chemical Robots (ChemBots) that would be soft, flexible and could manoeuvre through openings smaller than their static structural dimensions. They suggest that it could be made from shape-memory materials, electro- or magneto-rheological materials or even folding components. Does this sound like the T-1000 from Terminator 2 to anyone else? Yikes.
