+ - Dad and daughter recreated 'Jurassic Park' with $100,000 in Lego pieces->

Submitted by mpicpp
mpicpp (3454017) writes "ego pieces and dino-DNA — both considered "building blocks of life" and very useful for creating dinosaurs from scratch.

Animator Paul Hollingsworth and his daughter Hailee, along with some help from a few "master builders" — decided to recreate iconic scenes from Jurassic Park using only Lego pieces. More than $100,000 in Lego were used, according to the video's description.

The result is a surprisingly stunning and hilarious version of the 1993 dino-thriller. The team behind the film also released an in-depth behind-the-scenes look at the production."

+ - Amazon is Working to Replace Some Warehouse Workers->

Submitted by moon_unit2
moon_unit2 (2573409) writes "Amazon is organizing the event to spur the development of more nimble-fingered product-packing robots. Participating teams will earn points by locating products sitting somewhere on a stack of shelves, retrieving them safely, and then packing them into cardboard shipping boxes. Robots that accidentally crush a cookie or drop a toy will have points deducted. The contest is already driving new research on robot vision and manipulation, and it may offer a way to judge progress made in the past few years in machine intelligence and dexterity. Robots capable of advanced manipulation could eventually take on many simple jobs that are still done by hand."

+ - Sierra Nevada's Dream Chaser could land at Ellington Space Port near Houston->

Submitted by MarkWhittington
MarkWhittington (1084047) writes "Despite having been rejected in NASA’s commercial crew program, Sierra Nevada has been very busy trying to develop its lift body spacecraft, the Dream Chaser. Having rolled out a smaller, cargo version of the spacecraft for the second round for contracts for commercial cargo to the International Space Station, the company has amended the unfunded Space Act Agreement with NASA to add a closeout review milestone that would help transition the Dream Chaser from the preliminary design review to the critical design review step. Finally, Sierra Nevada announced a new agreement on Tuesday with the Houston Airport System to use Ellington Spaceport as a landing site for the cargo version of the Dream Chaser."

How Nuclear Weapon Modernization Undercuts Disarmament 225

Posted by Soulskill
from the perfecting-the-planetcracker dept.
Lasrick writes: John Mecklin details exactly how nuclear weapons modernization is kick-starting a new arms race, and how modernizing these weapons to make them more accurate and stealthy puts the world at even greater risk of nuclear war: "[T]his is precisely why the U.S. Congress rejected the Air Force’s requests for low-yield, precision-guided nuclear weapons in the 1990s: Their very accuracy increases the temptation to use them." The issue is not getting very much attention, but the patience of the non-nuclear states is wearing thin, and a breakthrough in public awareness may be on the horizon: "The disarmament debate is likely to make this spring's NPT conference a contentious one and just might be loud enough to make the public aware that a new type of nuclear arms race is unfolding around the world."

Do Robots Need Behavioral 'Laws' For Interacting With Other Robots? 125

Posted by Soulskill
from the don't-let-your-quake-3-bots-duel dept.
siddesu writes: Asimov's three laws of robotics don't say anything about how robots should treat each other. The common fear is robots will turn against humans. But what happens if we don't build systems to keep them from conflicting with each other? The article argues, "Scientists, philosophers, funders and policy-makers should go a stage further and consider robot–robot and AI–AI interactions (AIonAI). Together, they should develop a proposal for an international charter for AIs, equivalent to that of the United Nations' Universal Declaration of Human Rights. This could help to steer research and development into morally considerate robotic and AI engineering. National and international technological policies should introduce AIonAI concepts into current programs aimed at developing safe AIs."

No, It's Not Always Quicker To Do Things In Memory 472

Posted by Soulskill
from the performance-that-fails-to-perform dept.
itwbennett writes: It's a commonly held belief among software developers that avoiding disk access in favor of doing as much work as possible in-memory will results in shorter runtimes. To test this assumption, researchers from the University of Calgary and the University of British Columbia compared the efficiency of alternative ways to create a 1MB string and write it to disk. The results consistently found that doing most of the work in-memory to minimize disk access was significantly slower than just writing out to disk repeatedly (PDF).

Researchers Identify 'Tipping Point' Between Quantum and Classical Worlds 81

Posted by Soulskill
from the border-between-hostile-nations dept.
wjcofkc sends this report from R&D Magazine: If we are ever to fully harness the power of light for use in optical devices, it is necessary to understand photons — the fundamental unit of light. Achieving such understanding, however, is easier said than done. That's because the physical behavior of photons — similar to electrons and other sub-atomic particles — is characterized not by classical physics, but by quantum mechanics.

Now, in a study published in Physical Review Letters (abstract), scientists from Bar-Ilan University have observed the point at which classical and quantum behavior converge. Using a fiber-based nonlinear process, the researchers were able to observe how, and under what conditions, 'classical' physical behavior emerges from the quantum world.

Michael Stonebraker Wins Turing Award 34

Posted by Soulskill
from the much-deserved-recognition dept.
An anonymous reader writes: Michael Stonebraker, an MIT researcher who has revolutionized the field of database management systems and founded multiple successful database companies, has won the Association for Computing Machinery's $1 million A.M. Turing Award, often referred to as "the Nobel Prize of computing." In his previous work at the University of California at Berkeley, Stonebraker developed two of his most influential systems, Ingres and Postgres (PDF), which provide the foundational ideas — and, in many cases, specific source code — that spawned several contemporary database products, including IBM's Informix and EMC's Greenplum. Ingres was one of the first relational databases, which provide a more organized way to store multiple kinds of entities – and which now serve as the industry standard for business storage. Postgres, meanwhile, integrated Ingres' ideas with object-oriented programming, enabling users to natively map objects and their attributes into databases. This new notion of "object-relational" databases could be used to represent and manipulate complex data, like computer-aided design, geospatial data, and time series.

Wikipedia Admin's Manipulation "Messed Up Perhaps 15,000 Students' Lives" 260

Posted by Soulskill
from the going-for-the-high-score dept.
Andreas Kolbe writes: Recently, "ArbCom", Wikipedia's highest court, banned an administrator account that for years had been manipulating the Wikipedia article of a bogus Indian business school – deleting criticism, adding puffery, and enabling the article to become a significant part of the school's PR strategy. Believing the school's promises and advertisements, families went to great expense to send sons and daughters on courses there – only for their children to find that the degrees they had gained were worthless. "In my opinion, by letting this go on for so long, Wikipedia has messed up perhaps 15,000 students' lives," an Indian journalist quoted in the story says. India is one of the countries where tens of millions of Internet users have free access to Wikipedia Zero, but cannot afford the data charges to access the rest of the Internet, making Wikipedia a potential gatekeeper.

New Bill Would Repeal Patriot Act 184

Posted by Soulskill
from the would-also-bake-cookies-for-every-citizen dept.
schwit1 points out a new piece of bipartisan legislation that aims to repeal the Patriot Act and the FISA Amendments Act, which the NSA has used to justify broad domestic surveillance. House Representatives Thomas Massie (R-KY) and Mark Pocan (D-WI) introduced the bill yesterday, calling it the Surveillance State Repeal Act (PDF). Pocan said, "This isn't just tinkering around the edges. This is a meaningful overhaul of the system, getting rid of essentially all parameters of the Patriot Act." The bill also attempts to dramatically strengthen whistleblower protections, so situations like Edward Snowden's and Thomas Drake's don't happen in the future. This legislation is not expected to get the support of Congressional leaders, but supporters hope it will at least inspire some debate about several provisions of the Patriot Act coming up for renewal in June.
