Wendelstein 7-X Fusion Reactor Produces Its First Flash of Hydrogen Plasma

Slashdot - Fri, 05/02/2016 - 4:45pm
Zothecula writes: Experimentation with Germany's newest fusion reactor is beginning to heat up, to temperatures of around 80 million degrees Celsius, to be precise. Having fired up the Wendelstein 7-X to produce helium plasma late last year, researchers have built on their early success to generate its first hydrogen plasma, an event they say begins the true scientific operation of the world's largest fusion stellarator.

Have Your iPhone 6 Repaired, Only To Get It Bricked By Apple

Slashdot - Fri, 05/02/2016 - 4:26pm
New submitter Nemosoft Unv. writes: In case you had a problem with the fingerprint sensor or some other small defect on your iPhone 6 and had it repaired by a non-official (read: cheaper) shop, you may be in for a nasty surprise: error 53. What happens is that during an OS update or re-install the software checks the internal hardware and if it detects a non-Apple component, it will display an error 53 and brick your phone. Any photos or other data held on the handset is lost – and irretrievable. Thousands of people have flocked to forums to express their dismay at this. What's more insiduous is that the error may only appear weeks or months after the repair. Incredibly, Apple says this cannot be fixed by any hard- or software update, while it is clearly their software that causes the problem in the first place. And then you thought FTDI was being nasty ...

Grandma's Phone, DSL, and the Copper They Share

Slashdot - Fri, 05/02/2016 - 3:45pm
szczys writes: DSL is high-speed Internet that uses the same twisted pair of copper wire that still works with your Grandmother's wall-mounted telephone. How is that possible? The short answer is that the telephone company is cheating. But the long answer delves into the work of Claude Shannon, who figured out how much data could be reliably transferred using a given medium. His work, combined with that of Harry Nyquist and Ralph Hartley (pioneers of channel capacity and the role noise plays in these systems), brings the Internet Age to many homes on an infrastructure that has been in use for more than a hundred years.

UK Wants Authority To Serve Warrants In U.S.

Slashdot - Fri, 05/02/2016 - 3:04pm
schwit1 writes with this news, as reported by USA Today: British and U.S. officials have been negotiating a plan that could allow British authorities to directly serve wiretap orders on U.S. communications companies in criminal and national security inquiries, U.S. officials confirmed Thursday. The talks are aimed at allowing British authorities access to a range of data, from interceptions of live communications to archived emails involving British suspects, according to the officials, who are not authorized to comment publicly. ... Under the proposed plan, British authorities would not have access to records of U.S. citizens if they emerged in the British investigations. Congressional approval would be required of any deal negotiated by the two countries.

In Japan, a Battle Brewing Over the Right To Record 4k and 8k Broadcasts

Slashdot - Fri, 05/02/2016 - 2:23pm
AmiMoJo writes: Japanese broadcasters have indicated that 4k and 8k broadcasts may have recording disabled via a 'do not copy' flag [via Google Translate], which receivers would be expected to obey. Now the Internet Users Association (MIAU) and Shufuren (Housewives Federation) have submitted documentation opposing the ban. The document points out that the ban will only inconvenience the majority of the general audience, while inevitably failing to prevent unauthorized copying by anyone determined to circumvent the protection.

K-12 CS Framework Draft: Kids Taught To 'Protect Original Ideas' In Early Grades

Slashdot - Fri, 05/02/2016 - 1:42pm
theodp writes: Remember that Code.org and ACM-bankrolled K-12 Computer Science Education Framework that Microsoft, Google, Apple, and others were working on? Well, a draft of the framework was made available for review on Feb. 3rd, coincidentally just 3 business days after U.S. President Barack Obama and Microsoft President Brad Smith teamed up to announce the $4+ billion Computer Science for All initiative for the nation's K-12 students. "Computationally literate citizens have the responsibility to learn about, recognize, and address the personal, ethical, social, economic, and cultural contexts in which they operate," explains the section on Fostering an Inclusive Computing Culture, one of seven listed 'Core K-12 CS Practices'. "Participating in an inclusive computing culture encompasses the following: building and collaborating with diverse computational teams, involving diverse users in the design process, considering the implication of design choices on the widest set of end users, accounting for the safety and security of diverse end users, and fostering inclusive identities of computer scientists." Hey, do as they say, not as they do! Also included in the 10-page draft (pdf) is a section on Law and Ethics, which begins: "In early grades, students differentiate between responsible and irresponsible computing behaviors. Students learn that responsible behaviors can help individuals while irresponsible behaviors can hurt individuals. They examine legal and ethical considerations for obtaining and sharing information and apply those behaviors to protect original ideas."
