alphadogg (971356) writes "Canada Revenue Agency has halted online filing of tax returns by the country's citizens following the disclosure of the Heartbleed security vulnerability that rocked the Internet this week. The country's Minister of National Revenue wrote in a Twitter message on Wednesday that interest and penalties will not be applied to those filing 2013 tax returns after April 30, the last date for filing the returns, for a period equal to the length of the service disruption. The agency has suspended public access to its online services as a preventive measure to protect the information it holds, while it investigates the potential impact on tax payer information, it said."

theodp (442580) writes " Public school teachers," reads the headline at Khan Academy (KA), "introduce your students to coding and earn $1000 or more for your classroom!" Read the fine print, however, and you'll see that the Google-bankrolled offer is likely to ensure that girls, not boys, are going to be their Computer Science teachers' pets. "Google wants public high school students, especially girls, to discover the magic of coding," KA explains to teachers. "You'll receive a $100 DonorsChoose.org gift code for every female student who completes the [JS 101: Drawing & Animation] course. When 4 or more female students complete it, we'll email you an additional $500 gift code as a thank-you for helping your students learn to code." While "one teacher cannot have more than 20 of the $100 gift codes activated on their DonorsChoose.org projects," adds KA, "if the teacher has more than 20 female students complete the curriculum, s/he will still be sent gift codes, and the teacher can use the additional gift codes on another teacher's DonorsChoose.org project." So, is girls-are-golden-boys-are-worthless funding for teachers' projects incongruent with Khan Academy's other initiatives, such as its exclusive partnership with CollegeBoard to eliminate inequality among students studying for the SAT?"

mpicpp (3454017) writes in with news about accusations from Cuban officials about a spamming campaign against the country by the U.S.. "Cuban officials have accused the U.S. government of bizarre plots over the years, such as trying to kill Fidel Castro with exploding cigars. On Wednesday, they said Washington is using a new weapon against the island: spam. 'It's overloading the networks, which creates bad service and affects our customers,' said Daniel Ramos Fernandez, chief of security operations at the Cuban government-run telecommunications company ETECSA. At a news conference Wednesday, Cuban officials said text messaging platforms run by the U.S. government threatened to overwhelm Cuba's creaky communications system and violated international conventions against junk messages. The spam, officials claim, comes in the form of a barrage of unwanted text messages, some political in nature. Ramos said that during a 2009 concert in Havana performed by the Colombian pop-star Juanes, a U.S. government program blanketed Cuban cell phone networks with around 300,000 text messages over about five hours."

An anonymous reader writes "This article makes the case that most gamers treat 'free-to-play' games with derision and scorn when they really shouldn't. The author refers to it as 'snobbery.' We've all either encountered or heard about a game company using shady business practices to squeeze every cent from their users through in-app purchases (a.k.a. microtransations, a.k.a. cash shops), or a simple pay-to-win format. But these stories don't represent all games — by a long shot. It's something endemic to shady developers and publishers, not the business model. Think about traditionally-sold games, and how often you've seen a trailer that horribly misrepresents gameplay. Or a $60 game that was an unfinished, buggy mess. Or a Kickstarted project that didn't deliver on its promises. The author says, 'When something is new, when it isn't aimed at you, when it is created by strange people in strange places, when it breaks established norms and when it is becoming hugely popular... it's scary for the establishment. The ethical critique is an easy way to fight these changes, a call to protect the children or protect the irrational people who obviously can't like these games on their own merits. We begin to sound as reactionary as the ban on pinball or the fears over jazz music corrupting the minds of our youth.'"

pdclarry writes: "On April 8, Yahoo implemented a new DMARC policy that essentially bars any Yahoo user from accessing mailing lists hosted anywhere except on Yahoo and Google. While Yahoo is the initiator, it also affects Comcast, AT&T, Rogers, SBCGlobal, and several other ISPs. Internet Engineering Council expert John R. Levine, a specialist in email infrastructure and spam filtering, said, 'Yahoo breaks every mailing list in the world including the IETF's' on the Internet Engineering Task Force (IETF) list. DMARC (Domain-based Message Authentication, Reporting & Conformance) is a two-year-old proposed standard previously discussed on Slashdot that is intended to curb email abuse, including spoofing and phishing. Unfortunately, as implemented by Yahoo, it claims most mailing list users as collateral damage. Messages posted to mailing lists (including listserv, mailman, majordomo, etc) by Yahoo subscribers are blocked when the list forwards them to other Yahoo (and other participating ISPs) subscribers. List members not using Yahoo or its partners are not affected and will receive posts from Yahoo users. Posts from non-Yahoo users are delivered to Yahoo members. So essentially those suffering the most are Yahoo's (and Comcast's, and AT&T's, etc) own customers. The Hacker News has details about why DMARC has this effect on mailing lists. Their best proposed solution is to ban Yahoo email users from mailing lists and encourage them to switch to other ISPs. Unfortunately, it isn't just Yahoo, although they are getting the most attention."

An anonymous reader sends this news from CERN: "The Large Hadron Collider beauty (LHCb) collaboration today announced results that confirm the existence of exotic hadrons – a type of matter that cannot be classified within the traditional quark model. Hadrons are subatomic particles that can take part in the strong interaction – the force that binds protons inside the nuclei of atoms. Physicists have theorized since the 1960s, and ample experimental evidence since has confirmed, that hadrons are made up of quarks and antiquarks that determine their properties. A subset of hadrons, called mesons, is formed from quark-antiquark pairs, while the rest – baryons – are made up of three quarks. ... The Belle Collaboration reported the first evidence for the Z(4430) in 2008. They found a tantalizing peak in the mass distribution of particles that result from the decays of B mesons. Belle later confirmed the existence of the Z(4430) with a significance of 5.2 sigma on the scale that particle physicists use to describe the certainty of a result. LHCb reports a more detailed measurement of the Z(4430) that confirms that it is unambiguously a particle, and a long-sought exotic hadron at that. They analyzed more than 25,000 decays of B mesons selected from data from 180 trillion (180x10^12) proton-proton collisions in the Large Hadron Collider."

jones_supa (887896) writes "The British scientist Stuart Parkin, whose work made it possible for hard disks to radically expand in size, has been awarded the Millennium Technology Prize (Millennium-teknologiapalkinto). Professor Parkin's discoveries rely on magneto-resistive thin-film structures and the development of the giant magnetoresistance (GMR) spin-valve read head. These advances allow more information to be stored on each disk platter. Technology Academy Finland — the foundation behind the award — justifies the prize by saying that Parkin's innovations allow us to store large volumes of data in cloud services." He is currently working on Racetrack memory, which would obsolete flash and hard disks (and probably even RAM).

cartechboy (2660665) writes "When we were kids, we were promised flying cars in the future, like The Jetsons. Well, now it's the future, and we don't have any flying cars. But Land Rover just unveiled some crazy new technology called the Transparent Hood system. It's brilliant in its simplicity, and yet quite complex in its implementation. Using a web of camera images and projectors, the Transparent Hood system projects the area just in front of and underneath the nose of the vehicle onto a head-up display along the lower portion of the windshield. Not only is this obviously breathtaking, but when it comes to off-roading—or parking in tight urban spaces—this could change the game. It will allow drivers to see precisely what's below them and immediately in front of them allowing precise placement of the vehicle's front wheels. The system also displays key vehicle data including speed, incline, roll angle, steering position, and drive mode. People, this is the future, and the future is now."

KentuckyFC (1144503) writes "Last month, astronomers announced the discovery of the most distant body in the Solar System, a dwarf planet called 2012VP113. They also said this body's orbit was strangely aligned with several other dwarf planets in the Kuiper Belt and that this could be the result of these bodies being herded by a much larger Planet X even further from the Sun. They calculated that this hidden planet could be between 2 and 15 times the mass of the Earth and orbiting at a distance of between 200 AU and 300 AU, an announcement that triggered excited headlines around the world. Now it looks as though these predictions were wildly optimistic. It turns out that the position of Planet X can be constrained more tightly using orbital measurements of other planets. And when this data is added into the mix, Planet X can only only orbit at much greater distances, if it exists at all. The new calculations suggest that a planet twice the mass of Earth cannot orbit any closer than about 500 AU. And a planet 15 times the mass of Earth must be at least 1000 AU distant. What's more, the New Horizons mission currently on its way to Pluto, should constrain the distance to beyond 4700 AU. So any Planet X hunters out there are likely to be disappointed."

New submitter lashicd sends news that the U.S. Naval Research Laboratory has announced a successful proof-of-concept demonstration of converting seawater to liquid hydrocarbon fuel. They used seawater to provide fuel for a small replica plan running a two-stroke internal combustion engine. "Using an innovative and proprietary NRL electrolytic cation exchange module (E-CEM), both dissolved and bound CO2 are removed from seawater at 92 percent efficiency by re-equilibrating carbonate and bicarbonate to CO2 and simultaneously producing H2. The gases are then converted to liquid hydrocarbons by a metal catalyst in a reactor system. ... NRL has made significant advances in the development of a gas-to-liquids (GTL) synthesis process to convert CO2 and H2 from seawater to a fuel-like fraction of C9-C16 molecules. In the first patented step, an iron-based catalyst has been developed that can achieve CO2 conversion levels up to 60 percent and decrease unwanted methane production in favor of longer-chain unsaturated hydrocarbons (olefins). These value-added hydrocarbons from this process serve as building blocks for the production of industrial chemicals and designer fuels."

Individual pixels are hard to detect at first glance, making it a more immersive and comfortable experience in every single game and experience that we've tried.

bmahersciwriter writes: "We've all heard stories about how parasites can 'zombify' organisms, getting them to mindlessly protect a brood or infect their peers. Now UK researchers have figured out how one bacterial pathogen co-opts the behavior of a plant, causing it to attract sap-sucking insects that help the bacteria spread to other plants. From the story in Nature News: 'The plant appears alive, but it's only there for the good of the pathogen,' says plant pathologist Saskia Hogenhout from the John Innes Centre in Norwich, UK. 'In an evolutionary sense, the plant is dead and will not produce offspring.' 'Many might balk at the concept of a zombie plant because the idea of plants behaving is strange,' says David Hughes, a parasitologist at Pennsylvania State University in University Park. 'But they do, and since they do, why wouldn't parasites have evolved to take over their behavior, as they do for ants and crickets?'"

'The NSA has specifically targeted either leaders or staff members in a number of civil and non-governmental organizations including domestically within the borders of the United States.' Snowden, addressing the Council of Europe in Strasbourg, said he did not believe the NSA was engaged in 'nightmare scenarios,' such as the active compilation of a list of homosexuals 'to round them up and send them into camps.' But he did say that the infrastructure allowing this to happen had been built. Snowden made clear that he believed in legitimate intelligence operations but said the NSA should abandon its electronic surveillance of entire civilian populations. Instead, Snowden said, it should go back to the traditional model of eavesdropping against specific targets, such as 'North Korea, terrorists, cyber-actors, or anyone else.' Snowden also urged members of the Council of Europe to encrypt their personal communications and said that encryption, used properly, could still withstand 'brute force attacks' from powerful spy agencies and others. 'Properly implemented algorithms backed up by truly random keys of significant length all require more energy to decrypt than exists in the universe.'"

The difference between racing around a track on a TV screen and being behind the wheel of a real car on the asphalt is substantial — there's no reset button in real life. But Sony and Toyota have teamed up to blur that line with a new Sports Drive Logger device. It's a USB data logger that maps your real-world lines around a local racing circuit using the car's data systems and GPS coordinates. Using satellite positioning, pedal depression, steering angle, gear selection, engine revs, and vehicle speed, the Sports Drive Logger replicates this data in Gran Turismo 6. You use this data in the game's telemetry screen, or watch a virtual representation of the laps you've just driven, and even compare that data against your friend's data. If you're brave enough, you can compare your data to that of a professional driver's. Unfortunately this system is only available on the Japanese-spec Toyota GT 86 (a near-twin to the Scion FR-S and Subaru BRZ in the U.S.) — for now."
