PDP-11 Still Working In Nuclear Plants - For 37 More Years 252

Posted by Unknown Lamer
from the great-architectures-live-forever dept.
Taco Cowboy writes "Most of the younger /. readers never heard of the PDP-11, while we geezers have to retrieve bits and pieces of our affairs with PDP-11 from the vast warehouse inside our memory lanes." From the article: "HP might have nuked OpenVMS, but its parent, PDP-11, is still spry and powering GE nuclear power-plant robots and will do for another 37 years. That's right: PDP-11 assembler programmers are hard to find, but the nuclear industry is planning on keeping them until 2050 — long enough for a couple of generations of programmers to come and go." Not sure about the OpenVMS vs PDP comparison, but it's still amusing that a PDP might outlast all of the VAX machines.

Revisiting Amdahl's Law 47

Posted by Soulskill
from the looking-for-new-loopholes dept.
An anonymous reader writes "A German computer scientist is taking a fresh look at the 46-year old Amdahl's law, which took a first look at limitations in parallel computing with respect to serial computing. The fresh look considers software development models as a way to overcome parallel computing limitations. 'DEEP keeps the code parts of a simulation that can only be parallelized up to a concurrency of p = L on a Cluster Computer equipped with fast general purpose processors. The highly parallelizable parts of the simulation are run on a massively parallel Booster-system with a concurrency of p = H, H >> L. The booster is equipped with many-core Xeon Phi processors and connected by a 3D-torus network of sub-microsecond latency based on EXTOLL technology. The DEEP system software allows to dynamically distribute the tasks to the most appropriate parts of the hardware in order to achieve highest computational efficiency.' Amdahl's law has been revisited many times, most notably by John Gustafson."

Altering Text In eBooks To Track Pirates 421

Posted by Soulskill
from the for-whom-the-bell-jingles dept.
wwphx writes "According to Wired, 'German researchers have created a new DRM feature that changes the text and punctuation of an e-book ever so slightly. Called SiDiM, which Google translates to 'secure documents by individual marking,' the changes are unique to each e-book sold. These alterations serve as a digital watermark that can be used to track books that have had any other DRM layers stripped out of them before being shared online. The researchers are hoping the new DRM feature will curb digital piracy by simply making consumers paranoid that they'll be caught if they share an e-book illicitly.' I seem to recall reading about this in Tom Clancy's Patriot Games, when Jack Ryan used this technique to identify someone who was leaking secret documents. It would be so very difficult for someone to write a little program that, when stripping the DRM, randomized a couple of pieces of punctuation to break the hash that the vendor is storing along with the sales record of the individual book."

Bob the Super Hamste writes "The St. Paul Pioneer press is reporting that Comcast is planning on expanding its network of public WiFi hot spots in the Twin Cities area by using home internet connections and user's WiFi routers. Customers will be upgraded to new wireless routers that will have 2 wireless networks, one for the home users and one for the general public. Subscribers to Comcast's Xfinity service and customers that participate in the public WiFi program will be allowed free access to the public WiFi offered by this service. Non Comcast customers get 2 free sessions a month each lasting 1 hour with additional sessions costing money. The article mentions that a similar service already exists and is provided by the Spain-based company Fon."

Ask Slashdot: Neurofeedback At Home, Is It Possible? 68

Posted by Soulskill
from the what-could-possibly-go-wrong dept.
New submitter sker writes "Mind hackers, self-help junkies, even regular people have heard wild promises of the power of neurofeedback — namely the process of watching a visual representation of your own brain's activity to influence what your brain is doing. Folks are using it to cure ADHD, PTSD, or even to supposedly improve mindfulness meditation. Previously the sole domain of costly hospital and research equipment, the necessary EEG equipment is making its way into the home. From newagey Deepak Chopra-endorsed kits to the for-engineers-only OpenEEG project, the options are rapidly getting unwieldy for curious bystanders to make sense of. Have you had experience with EEG or neurofeedback at home? Do you have advice?"

Facebook's Complaint Process Is Arbitrary — But So Is Campaigning 113

Posted by timothy
from the please-don't-call-it-a-witch-hunt dept.
Bennett Haselton writes "After initial abuse reports failed to shut down some anti-women and pro-rape pages on Facebook, a wider lobbying campaign succeeded in prompting a Facebook policy change. This has been alternately hailed as a vindication of the campaigner's cause, or derided as proof that Facebook can be cowed by humorless feminists. In reality, the success of the campaign was most likely the outcome of a mostly arbitrary and random process that required a lot of luck, just as the initial abuse reports didn't succeed because they didn't have the necessary luck on their side. Neither result should be taken to reflect on the merits of the campaigner's actual points." Read on for the rest of Bennett's thoughts.

Your License Is Your Interface 352

from the your-license-is-solid-color-rectangles dept.
dp619 writes "License-free software has become a thing. Only 14.9% of repositories on GitHub have a license, according to recent Software Freedom Law Center research. Red Monk has observed that this trend is occurring principally among younger software developers. Outercurve Foundation technical evangelist Eric Schultz has offered up his opinion, saying, 'As an active developer I want to add a slightly different perspective on the dangers of releasing unlicensed software. My perspective is based on a simple phrase: "Your License Is Your Interface."' He adds, 'A license similarly defines the interaction between the software, or more precisely the creators of the software, and users. Just like an interface, a license defines intended behavior of users of the software, such as the four essential freedoms or the ten pillars of the Open Source Definition. Just like an interface, a license prevents unintended behavior of users of the software, which depending on the open source license, may disclaim the original author of liability for use of the software, prohibit redistribution without recognizing the original author or prohibit distribution of derivatives under a more restrictive license. When it comes to legal use and distribution of your software, your license IS your interface.'"

Computer Memory Can Be Read With a Flash of Light 69

Posted by Soulskill
from the whose-bright-idea-was-this dept.
ananyo writes "A new kind of computer memory can be read 10,000 times faster than flash memory using pulses of light, taking advantage of principles used in solar panel design. Researchers built the prototype device using bismuth ferrite. In conventional computer memory, information is stored in cells that hold different amounts of electric charge, each representing a binary '1' or '0.' Bismuth ferrite, by contrast, and can represent those binary digits, or bits, as one of two polarization states, and, because of its photovoltaic properties, can switch between these states in response to visible light."

Federal Judge Says Interns Should Be Paid 540

Posted by Unknown Lamer
from the businesses-hate-it-so-it-must-be-right dept.
An anonymous reader writes "Student interns are typically relegated to menial tasks like fetching coffee and taking out the trash, the idea being that they get paid in experience instead of money. On Tuesday, Manhattan Federal District Court Judge William H. Pauley disagreed, ruling in favor of two interns who sued Fox Searchlight Pictures to be paid for their work on the 2010 film Black Swan. The interns did chores that otherwise would have been performed by paid employees. Pauley ruled, in accordance with criteria laid out by the U.S. Department of Labor, that unpaid internships should be educational in nature and specifically structured to the benefit of the intern, and reasoned that if interns are going to do grunt work like regular employees, then they should be paid like regular employees." The article seems to imply that this might be the beginning of the end for the rampant abuse of unpaid internships: "Judge Pauley rejected the argument made by many companies to adopt a 'primary benefit test' to determine whether an intern should be paid, specifically whether 'the internship’s benefits to the intern outweigh the benefits to the engaging entity.' Judge Pauley wrote that such a test would be too subjective and unpredictable."

International Linear Collider Design Ready To Go 71

Posted by Unknown Lamer
from the better-atom-smashing-through-science dept.
Via El Reg comes news that the International Linear Collider's Technical Design Report is finished, leaving only funding in the way of construction. From the article: "A five volume report containing the plans for the International Linear Collider has been handed over to the International Committee for Future Accelerators (ICFA) for approval. The Technical Design Report contains costings for the project, along with the design of the new collider. The new machine is significantly more powerful than the hoary European Large Hadron Collider and is likely to be sited in Japan, because the Pacific island nation has reportedly offered to pay for half of the construction costs. ... Jonathan Bagger, chair of the International Linear Collider Steering Committee, said the particle collider was 'ready to go.' 'The publication of the Technical Design Report represents a major accomplishment,' he continued. ... The ILC consists of two linear accelerators facing each other.

Slashdot Asks: How Will You Replace Google Reader? 334

from the bifocals-espresso-and-page-ruffling-servants dept.
Despite a hue and cry from disappointed users, Google has not made any moves to reverse its decision to close down Google Reader on the first of July, just a few weeks away. Despite the name — and the functions it started out with in 2001 — Reader has become more than a simple interface to RSS feeds; Wikipedia gives a concise explanation of how it evolved from just a few features to a full-blown platform of its own, incorporating social-sharing features of the kind that have become expected in many online apps. Those features have morphed over the years along with Google's larger social strategies, along the way upsetting some readers who'd grown used to certain features. If you're a Google Reader user, will you be replacing it with another aggregator?

Apple Updates MacBooks and Mac Pro Desktop With Haswell, "Unified Thermal Core" 463

Posted by Unknown Lamer
from the next-cube-on-drugs dept.
MojoKid writes with more detailed information on the new hardware Apple announced earlier today at WWDC "On the hardware side, Apple is updating its two MacBook Air devices; both the 11-inch and 13-inch versions will enjoy better battery life (up to 9 hours and 12 hours, respectively), thanks in no small part to having Intel's new Haswell processors inside. They'll also have 802.11ac WiFi on board. Both models have 1.3GHz Intel Core i5 or i7 (Haswell) processors, Intel HD Graphics 5000, 4GB of RAM, and has 128GB or 256GB of flash storage. Arguably the scene stealer on the desktop side of things is a completely redesigned Mac Pro. The 9.9-inch tall cylindrical computer boasts a new 'unified thermal core' which is designed to conduct heat away from the CPU and GPU while distributing it uniformly and using a single bottom-mounted intake fan. It rocks a 12-core Intel Xeon processor, dual AMD FirePro GPUs (standard), 1866MHz DDR3 ECC memory (60GBps), and PCIe flash storage with up to 1.25GBps read speeds. The system promises 7 teraflops of graphics performance, supports 4k displays, and has a host of ports including four USB 3.0, two gigabit Ethernet ports, HDMI 1.4, six Thunderbolt 2 ports that offer super-fast (20Gbps) external connectivity."

The Rails Girls Are Coming to a City Near You (Video) 162

Posted by Roblimo
from the programming-not-trains dept.
So far, the Rails Girls have groups in cities ranging from Warsaw to Wellington, with U.S. gatherings in Washington D.C., Charlotte NC, San Francisco CA, and... let's make it easy: Here's a map. OMG! They're everywhere! Actually, mostly Europe, being as they started in Finland, same as the Leningrad Cowboys and a popular computer operating system. But they're spreading like mad. Would you believe the reason one of the two founders originally got interested in Ruby on Rails was because she wanted to make a fan page for American politician Al Gore? Our interviewee, Magda (from Rails Girls Warsaw), swears this is true. She also tells us about their upcoming Washington D.C. workshop on June 13th, 2013, in conjunction with the June 14-15 RubyNation event. Sounds like fun, doesn't it. Maybe you need more of this kind of fun where you live, eh? If there isn't a Rails Girls group near you, maybe you should start one and help more women and girls get into programming. This is the Rails Girls' goal. Any particular ages? Not really. And their workshops are all free of charge: "You just need to be excited!"

from the it-already-does dept.
aarondubrow writes "For more than 50 years, linguists and computer scientists have tried to get computers to understand human language by programming semantics as software, with mixed results. Enabled by supercomputers at the Texas Advanced Computing Center, University of Texas researchers are using new methods to more accurately represent language so computers can interpret it. Recently, they were awarded a grant from DARPA to combine distributional representation of word meanings with Markov logic networks to better capture the human understanding of language."

Seeking Fifth Amendment Defenders 767

from the if-you-have-nothing-to-hide dept.
Bennett Haselton writes with his take on a case going back and forth in U.S. courts right now about whether a defendant can be ordered to decrypt his own hard drives when they may incriminate him. "A Wisconsin defendant in a criminal child-pornography case recently invoked his Fifth Amendment right to avoid giving the FBI the password to decrypt his hard drive. At the risk of alienating fellow civil-libertarians, I admit I've never seen the particular value of the Fifth Amendment right against self-incrimination. So I pose this logical puzzle: come up with a specific, precisely defined scenario, where the Fifth Amendment makes a positive difference." Read on for the rest of Bennett's thoughts.

ColdWetDog writes "The LA Times has a quick article on a newly named giant lizard: 'An ancient plant eating lizard that looked like an iguana but was closer in size to a German shepherd has been named after Jim Morrison, the late troubled and charismatic lead singer of the Doors.The lizard's name was chosen by Jason Head, a paleontologist at the University of Nebraska-Lincoln and a hard-core Doors fan since college.' Hunter S. Thompson, who hallucinated presumably somewhat more carnivorous lounge lizards, was also considered for the honor."
