Forget CPU and GPU already. The mining difficulty has risen so much recently that what you can mine with them today won't event offset the power costs.

ASICs are the only viable option today for at-home mining, but I'm pretty sure they'll also be rendered useless soon by hosted mining services (CEX.IO already has 25% of the whole Bitcoin network mining power) that are able to consolidate costs and run their mining farms in countries with cheap electricity.

Why Your Users Hate Agile 597

Esther Schindler writes "What developers see as iterative and flexible, users see as disorganized and never-ending. This article discusses how some experienced developers have changed that perception. '... She's been frustrated by her Agile experiences — and so have her clients. "There is no process. Things fly all directions, and despite SVN [version control] developers overwrite each other and then have to have meetings to discuss why things were changed. Too many people are involved, and, again, I repeat, there is no process.' The premise here is not that Agile sucks — quite to the contrary — but that developers have to understand how Agile processes can make users anxious, and learn to respond to those fears. Not all those answers are foolproof. For example: 'Detailed designs and planning done prior to a project seems to provide a "safety net" to business sponsors, says Semeniuk. "By providing a Big Design Up Front you are pacifying this request by giving them a best guess based on what you know at that time — which is at best partial or incorrect in the first place." The danger, he cautions, is when Big Design becomes Big Commitment — as sometimes business sponsors see this plan as something that needs to be tracked against. "The big concern with doing a Big Design up front is when it sets a rigid expectation that must be met, regardless of the changes and knowledge discovered along the way," says Semeniuk.' How do you respond to user anxiety from Agile processes?"

Prof. Stephen Hawking: Great Scientist, Bad Gambler 231

astroengine writes "World-renowned physicist Stephen Hawking has announced that he was likely wrong about his view that the Higgs boson doesn't exist — an outcome he doesn't find very exciting — conceding that he lost a $100 wager. Speaking at the Beckman Auditorium in Caltech, Pasadena, Calif., on Tuesday (April 16), the British physicist gave a public lecture on 'The Origins of the Universe,' summarizing new revelations in modern astrophysics and cosmology. After the lecture, Caltech physicist and colleague John Preskill commented on Hawking's fondness for placing bets when faced with conflicts of physics ideas. Hawking lost a famous wager to Preskill in 2004 in a debate over whether or not black holes destroy information (theory suggests they do not, opposing Hawking's argument). 'To love Stephen Hawking is to not always agree with Stephen Hawking,' Preskill quipped. 'He's usually right, but he's not always right. Sometimes we haven't been able to resolve our differences and we've resorted to making bets it's sad to say that although Stephen Hawking is without doubt a great scientist, he's a bad gambler.'"

Film Studios Send Takedown Notices About Takedown Notices 197

another random user sends this excerpt from the BBC: "Two film studios have asked Google to take down links to messages sent by them requesting the removal of links connected to film piracy. Google receives 20 million 'takedown' requests, officially known as DMCA (Digital Millennium Copyright Act) notices, every month. They are all published online. Recent submissions by Fox and Universal Studios include requests for the removal of previous takedown notices. ... By making the notices available, Google is unintentionally highlighting the location of allegedly pirated material, say some experts. 'It would only take one skilled coder to index the URLs from the DMCA notices in order to create one of the largest pirate search engines available,' wrote Torrent Freak editor Ernesto Van Der Sar on the site."

Comment Re:Q: Why are we still on x86 and 64bit and not 12 (Score 4, Informative) 151

Don't mix up addressing and computing.

The whole internet would fit in a 64 bit address space, there is really absolutely no need at all for more than 64 bit for addresses in CPUs, that's why x86_64 and other 64 bit archs are here to stay, and you'll probably never see "128 bit" processors at all.

On the other side, today's x86_64 CPUs are capable of 128 bit (SSE) and 256 bit (AVX) computing. The width of the compute units is also bound to increase for some time, with Intel already planning to go 1024 bit in the not-so-far future.

Is OpenStack the New Linux? 185

snydeq writes "As the self-proclaimed 'cloud OS for the datacenter,' OpenStack is fast becoming one of the more intriguing movements in open source — complete with lofty ambitions, community in-fighting, and commercial appeal. But questions remain whether this project can reach its potential of becoming the new Linux. 'The allure of OpenStack is clear: Like Linux, OpenStack aims to provide a kernel around which all kinds of software vendors can build businesses. But with OpenStack, we're talking multiple projects to provide agile cloud management of compute, storage, and networking resources across the data center — plus authentication, self-service, resource monitoring, and a slew of other projects. It's hugely ambitious, perhaps the most far-reaching open source project ever, although still at a very early stage. ... Clearly, the sky-high aspirations of OpenStack both fuel its outrageous momentum and incur the risk of overreach and collapse, as it incites all manner of competition. The promise is big, but the success of OpenStack is by no means assured.'"

Grant To Allow Khan Academy To Expand, Build a Physical School 92

mayberry42 writes with this news snipped from Hack Education: "Khan Academy announced this morning that it has raised $5 million from the O'Sullivan Foundation (a foundation created by Irish engineer and investor Sean O'Sullivan). The money is earmarked for several initiatives: expanding the Khan Academy faculty, creating a content management system so that others can use the program's learning analytics system, and building an actual brick-and-mortar school, beginning with a summer camp program."

Second Life Mine Simulation Receives an Emmy Nomination 65

An anonymous reader writes "The Virtual Mine, an interactive simulation set in the virtual world of Second Life designed to examine the effects of mountaintop coal mining, has been nominated for an Emmy Award for new approaches to news and documentary programming. From the article: 'The Virtual Mine allows visitors to take a closer look at the challenges of balancing the environment, power demands, and economic interests by inviting them to take part in a story as it unfolds through a series of three games. While it was created with educators and students in mind, the games can be played in groups or by individuals alike.'"
