Comment Brazil's PIX has no fee (Score 1) 45

by tmpsantos (#63539161) Attached to: The Country With the Most DIgital Payments: India
It is instant money transfer with *no fees*. Small shops will give you the same discount as if you pay with cash (around 5% or the credit card fee). The system is really handy, as you can associate your phone number or email to your PIX so it serves as a handle/alias when you receive money. You can also generate a random key to disclose less data with the sender. The challenge has been educate the population and make the system safe against scammers and regular muggers. It is a lot easier for scammers to mass message people on WhatsApp and lure them to send some money. Also you might get forced to send money to a temporary account (usually a owned by someone that has no idea about it, another victim) at gunpoint, so another criminal will withdraw the money at an ATM. Pix is improving and the mass adoption tells it was well received by the population, specially small business. For the people concerned about digital cash, government overwatch, etc it is a valid conversation to have, but remember that in Brazil you will deposit your paper money in the bank anyway because it is just not safe to carry big sums of money around.

Quake On an Oscilloscope 71

Posted by Soulskill from the rocket-jump-with-an-electromagnet dept.
An anonymous reader writes: Developer Pekka Väänänen has posted a fascinating report on how he got Quake running on an oscilloscope (video link). Obviously, the graphic details gets stripped down to basic lines, but even then, you need to cull any useless or unseen geometry to make things run smoothly. He says, "To cull the duplicates a std::unordered_set of the C++ standard library is used. The indices of the triangle edges are saved in pairs, packed in a single uint64_t, the lower index being first. The set is cleared between each object, so the same line could still be drawn twice or more if the same vertices are stored in different meshes. Before saving a line for end-of-the-frame-submit, its indices in the mesh are checked against the set, and discarded if already saved this frame. At the end of each frame all saved lines are checked against the depth buffer of the rendered scene. If a line lies completely behind the depth buffer, it can be safely discarded because it shouldn't be visible."

Norway Rejects Bitcoin As Currency; Taxes As Asset, Instead 245

Posted by timothy from the money-need-not-derive-from-the-state dept.
An anonymous reader writes "Norway is the latest country to consider the legal implications of cryptocurrencies like Bitcoin. Norway's director general of taxation has come out and said '[Bitcoin] doesn't fall under the usual definition of money,' which means that it will be considered as assets and charged under capital gains laws. This sentiment was echoed last week by the European banking authority as well, where citizens were warned of using the cyrptocurrency."

Emscripten and New Javascript Engine Bring Unreal Engine To Firefox 124

Posted by Unknown Lamer from the cycle-is-nearly-complete dept.
MojoKid writes "There's no doubt that gaming on the Web has improved dramatically in recent years, but Mozilla believes it has developed new technology that will deliver a big leap in what browser-based gaming can become. The company developed a highly-optimized version of Javascript that's designed to 'supercharge' a game's code to deliver near-native performance. And now that innovation has enabled Mozilla to bring Epic's Unreal Engine 3 to the browser. As a sort of proof of concept, Mozilla debuted this BananaBread game demo that was built using WebGL, Emscripten, and the new JavaScript version called 'asm.js.' Mozilla says that it's working with the likes of EA, Disney, and ZeptoLab to optimize games for the mobile Web, as well." Emscripten was previously used to port Doom to the browser.

Did Steve Jobs Pick the Wrong Tablet Size? 433

Posted by Soulskill from the nobody's-perfect dept.
An anonymous reader writes "During the 2010 Christmas shopping season, Steve Jobs famously dissed the 7-inch tablets being rolled out by competitors, including Samsung's Galaxy, as being 'tweeners: too big to compete with a smartphone and too small to compete with the [9.7-inch diagonal] iPad,' adding that 'the current crop of 7-inch tablets are going to be DOA — dead on arrival.' A year later Jobs was dead, and the iPad Mini, with a 7.9-inch diagonal screen, was rolled out under his successor Tim Cook in October, 2012. Looking at industry-wide tablet sales numbers for January 2013, which show that the iPad Mini surprisingly outsold its larger sibling by a substantial margin (as did 7-inch Android tablets from competitors), Motley Fool's Evan Niu thinks that the 7.9-inch form factor was the correct size all along, contrary to Jobs' pronouncements (which, of course, was partly marketing bluster — but he chose the larger size in the first place). Of course the Mini is cheaper, but not by much — $329 vs. $399 for the larger iPad, for the baseline model with WiFi only and 16GB storage. Had Apple introduced the iPad with the smaller size to begin with, Niu argues, competitors would have faced a much more difficult task grabbing market share. While the Mini is currently available only with 'Super VGA' resolution (1024x768), rumors are afloat that Minis with the Retina display (2048x1536) are close to production."

Movie Studios Ask Google To Censor Links To Legal Copies of Their Own Films 196

Posted by Soulskill from the don't-you-dare-point-at-my-stuff dept.
An anonymous reader writes "Several large movie studios have asked Google to take down legitimate pages related to their own films, including sites legally hosting, promoting, or discussing them. Victims of the takedown requests include sites where the content is hosted legally (Amazon, CBS, iTunes, Blockbuster, Verizon on demand, and Xfinity), newspapers discussing the content in question (the BBC, CNET, Forbes, The Huffington Post, The Guardian, The Independent, The Mirror, The Daily Mail, and Wired) as well as official Facebook Pages for the movies and TV shows and even their Wikipedia entries. There are also a number of legitimate links that appear to be completely unrelated to the content that is supposedly being protected. The good news is that Google has so far left many of the links up."

Auto-threading Compiler Could Restore Moore's Law Gains 404

Posted by Unknown Lamer from the sufficiently-smart-compiler dept.
New submitter Nemo the Magnificent writes "Develop in the Cloud has news about what might be a breakthrough out of Microsoft Research. A team there wrote a paper (PDF), now accepted for publication at OOPSLA, that describes how to teach a compiler to auto-thread a program that was written single-threaded in a conventional language like C#. This is the holy grail to take advantage of multiple cores — to get Moore's Law improvements back on track, after they essentially ran aground in the last decade. (Functional programming, the other great hope, just isn't happening.) About 2004 was when Intel et al. ran into a wall and started packing multiple cores into chips instead of cranking the clock speed. The Microsoft team modified a C# compiler to use the new technique, and claim a 'large project at Microsoft' have written 'several million lines of code' testing out the resulting 'safe parallelism.'" The paper is a good read if you're into compilers and functional programming. The key to operation is adding permissions to reference types allowing you to declare normal references, read-only references to mutable objects, references to globally immutable objects, and references to isolated clusters of objects. With that information, the compiler is able to prove that chunks of code can safely be run in parallel. Unlike many other approaches, it doesn't require that your program be purely functional either.

12 Dead, 50 Injured at The Dark Knight Rises Showing In Colorado 1706

Posted by Soulskill from the rest-in-peace dept.
beaverdownunder sends the sad news that a gunman opened fire on an audience watching the new Batman movie early this morning, killing 12 and wounding 50 others. The shooting took place in Aurora, Colorado, and the suspect was arrested by police. "Witnesses told KUSA that the gunman kicked in an emergency exit door and threw a smoke bomb into the darkened theater before opening fire. One movie-goer, who was not identified, told KUSA the gunman was wearing a gas mask. Some people in the audience thought the thick smoke and gunfire was a special effect accompanying the movie, police and witnesses said."

Accountability, Not Code Quality, Makes iOS Safer Than Android 210

Posted by timothy from the well-it-isn't-obscurity dept.
chicksdaddy writes "Threatpost is reporting on a new study of mobile malware that finds accountability, not superior technology, has kept Apple's iOS ecosystem free of viruses, even as the competing Android platform strains under the weight of repeated malicious code outbreaks. Dan Guido of the firm Trail of Bits and Michael Arpaia of iSEC Partners told attendees at the SOURCE Boston Conference on Thursday about an empirical analysis of existing malicious programs for the Android and iOS platforms which shows that Google is losing the mobile security contest badly — every piece of malicious code the two identified was for the company's Android OS, while Apple's iOS remained free of malware, despite owning 30% of the mobile smartphone market in the U.S. Apple's special sauce? Policies that demand accountability from iOS developers, and stricter controls on what applications can do once they are installed on Apple devices."
