Privacy Advocate Jacob Appelbaum Reports Break-In Of Berlin Apartment http://rss.slashdot.org/~r/Slashdot/slashdot/~3/_XKoheZc-dQ/story01.htm http://slashdot.feedsportal.com/c/35028/f/647410/s/351b1623/sc/8/l/0Lyro0Bslashdot0Borg0Cstory0C130C120C220C16232450Cprivacy0Eadvocate0Ejacob0Eappelbaum0Ereports0Ebreak0Ein0Eof0Eberlin0Eapartment0Dutm0Isource0Frss10B0Amainlinkanon0Gutm0Imedium0Ffeed/story01.htm Jacob Appelbaum isn't shy about his role as a pro-privacy (and anti-secrecy) activist and hacker. A long-time contributor to the Tor project, and security researcher more generally, Appelbaum stood in for the strategically absent Julian Assange at HOPE in 2010, and more recently delivered Edward Snowden's acceptance speech when Snowden was awarded the Government Accountability Project's Whistleblower Prize. Now, he reports, his Berlin apartment appears to have been burglarized, and his computers tampered with. As reported by Deutsche Welle, "Appelbaum told [newspaper the Berliner Zeitung] that somebody had broken into his apartment and used his computer in his absence. 'When I flew away for an appointment, I installed four alarm systems in my apartment,' Appelbaum told the paper after discussing other situations which he said made him feel uneasy. 'When I returned, three of them had been turned off. The fourth, however, had registered that somebody was in my flat - although I'm the only one with a key. And some of my effects, whose positions I carefully note, were indeed askew. My computers had been turned on and off.'" It's not the first time by any means that Appelbaum's technical and political pursuits have drawn attention of the unpleasant variety. Read more of this story at Slashdot.       | | 5:24p |

Is Computer Science Education Racist and Sexist? http://rss.slashdot.org/~r/Slashdot/slashdot/~3/OMTJ92RoD1k/story01.htm http://slashdot.feedsportal.com/c/35028/f/647410/s/351b98ce/sc/4/l/0Lnews0Bslashdot0Borg0Cstory0C130C120C220C19222380Cis0Ecomputer0Escience0Eeducation0Eracist0Eand0Esexist0Dutm0Isource0Frss10B0Amainlinkanon0Gutm0Imedium0Ffeed/story01.htm theodp writes "What's wrong with this picture?" asked Code.org at its launch earlier this year, lamenting the lack of Computer Science students in a race and gender reference-free infographic. But as the organization has grown via public/private partnerships and inked agreements to drive the CS curriculum for the Chicago and NYC school systems, the same stats webpage has adopted a new gender and racial equity focus, positioning Computer Science education as "a chance to level the playing field" for women, Hispanic and African American students. The new message is consistent with the recently-forged Code.org partnership with the NSF-funded Exploring Computer Science (ECS, "a K-12/university partnership committed to democratizing computer science") and Computer Science Principles (CSP, "a new course under development that seeks to broaden participation in computing and computer science"). According to The Research Behind ECS, an "insidious 'virtual segregation' that maintains inequality" is to blame for keeping the number of African Americans and Latino/as CS students disproportionately low. So, what might the future of Code.org's proposed equity-based U.S. K-12 CS education look like? "Including culturally relevant instructional materials represented a driving focus of our course development," explained ECS Team members who now advise Code.org. "Cultural design tools encourage students to artistically express computing design concepts from Latino/a, African American, or Native American history as well as cultural activities in dance, skateboarding, graffiti art, and more. These types of lessons are important for students to build personal relationships with computer science concepts and applications – an important process for discovering the relevance of computer science for their own life." And — ironically for Code.org — it could mean less coding." Read more of this story at Slashdot.       | | 8:22p |

Asm.js Gets Faster http://rss.slashdot.org/~r/Slashdot/slashdot/~3/2DkEtEwO3Tk/story01.htm http://slashdot.feedsportal.com/c/35028/f/647410/s/351cc5af/sc/4/l/0Ldevelopers0Bslashdot0Borg0Cstory0C130C120C220C2222250A0Casmjs0Egets0Efaster0Dutm0Isource0Frss10B0Amainlinkanon0Gutm0Imedium0Ffeed/story01.htm mikejuk writes "Asm.js is a subset of standard JavaScript that is simple enough for JavaScript engines to optimize. Now Mozilla claims that with some new improvements it is at worst only 1.5 times slower than native code. How and why?The problem with JavaScript as an assembly language is that it doesn't support the range of datatypes that are needed for optimization. This is good for human programmers because they can simply use a numeric variable and not worry about the difference between int, int32, float, float32 or float64. JavaScript always uses float64 and this provides maximum precision, but not always maximum efficiency. The big single improvement that Mozilla has made to its SpiderMonkey engine is to add a float32 numeric type to asm.js. This allows the translation of float32 arithmetic in a C/C++ program directly into float32 arithmetic in asm.js. This is also backed up by an earlier float32 optimization introduced into Firefox that benefits JavaScript more generally. Benchmarks show that firefox f32 i.e. with the float32 type is still nearly always slower than native code, it is now approaching the typical speed range of native code. Mozilla think that this isn't the last speed improvement they can squeeze from JavaScript. So who needs native code now?" Read more of this story at Slashdot.       | | 11:25p |
