Ein Verschlüsselungstrojaner sorgt für Aufregung und Schlagzeilen. So warnen das Bundesamt für Sicherheit in der Informationstechnik (BSI) und die polizeiliche Kiminalprävention der Länder und des Bundes vor einer besonders dreisten Variante von Schadsoftware. Kriminelle versuchen damit, Geld von PC-Besitzern zu erpressen. Bei den Attacken werden die PCs von Betroffenen so verschlüsselt, dass eine vollständige Wiederherstellung aller Daten oft nicht möglich ist.

Apple und Samsung haben in dem mit Spannung erwarteten Patentprozess in Kalifornien ihre gegenseitigen Ideenklau-Vorwürfe bekräftigt. Der südkoreanische Konkurrent habe die bewusste Entscheidung getroffen, iPhone und iPad zu kopieren, sagte Apple-Anwalt Harold McElhinny in seiner Eröffnungs-Erklärung vor den Geschworenen am Dienstag laut US-Medienberichten. Als Beleg demonstrierte er Fotos von Samsung-Geräten vor und nach der Vorstellung des iPhone.

jones_supa writes "Gamasutra editor Eric Schwarz gives thought to the constantly increasing amount of graphical detail in computer games. He notes how the cues leading the player can be hindered too much if they drown in the surroundings, making it harder for the game to hint whether the player is making progress. Consistent visual language helps to categorize various objects, making their meaning more obvious. Paths through the game world can be difficult to read simply due to dense vegetation. For some cases 'obfuscation through detail' can also actually work really well. Schwarz challenges us to ponder how the amount of detail makes a game either more or less enjoyable."

Virtual reality headsets have historically been very disappointing. While the concept has been fun and interesting, the technological realities never quite lived up to expectations, and hardware developers largely gave up on research into this kind of device. However, it's been long enough that display technology has caught up to our ambitions. So, where are our VR headsets? Well, hobbyist Palmer Luckey asked that same question, and when he couldn't find a good answer, he decided to build one himself. He and his team have built a prototype, and they just launched a Kickstarter campaign to distribute developer kits. The campaign blew past its $250,000 goal in hours. What's interesting about this particular campaign is that Palmer took the Oculus Rift to various development studios and managed to get enthusiastic endorsements from some big names, including Cliff Bleszinski, Gabe Newell, and John Carmack.

An anonymous reader tips news that Google has sent out a letter to app developers explaining policy changes for any new apps published on the Google Play store. In-app purchases must now use Google Play's payment system unless it's for goods or services used outside the app itself. They've added language to dissuade developers from making their apps look like other apps, or like they come from other developers. But more significantly, Google has explained in detail what qualifies as spam: repetitive content, misleading product descriptions, gaming the rating system, affiliate traffic apps, or apps that send communications without user consent. Also, advertisements within apps must now follow the same rules as the app itself, and they can't be intrusive: Ads can't install things like shortcuts or icons without consent, they must notify the user of settings changes, they can't simulate notifications, and they can't request personal information to grant full app function.

ananyo writes "Physicists, chemists and mathematicians in the UK are campaigning against their chief public funder (EPSRC) over reforms that they say threaten blue-skies research, kicking off their protest by toting a coffin to the Prime Minister in Downing Street. The reforms are a response to declining budgets and political pressure to focus science on areas that will produce economic benefits for the UK. Last month, over 2000 Canadian scientists marched to Parliament Hill with a coffin to protest against the Harper government's cuts to basic research and scientific facilities, which they believe undermine the quality of scientific evidence in government. With budget cuts to science expected in the U.S., is it time for scientists in U.S. — and perhaps elsewhere — to think about getting their retaliation in first and ready their coffins?"

colinneagle writes "Twitter today launched a new tool that leverages its estimated 400 million daily Tweets to gauge public opinion on the candidates for the 2012 presidential election. Progress in political polling is long overdue, and with Twitter providing a constant, international conversation for web users to join or leave at their own will, there may not be a better time than now to make that change. However, there are some concerns. One of the interesting points made in Twitter's description of its new tool is where it claims to be 'illustrating instances when unprompted, natural conversation deviates from responses to specific survey questions.' That assumes conversation on Twitter is natural. If parody accounts, Twitter trolls, and spam bots have taught us anything (and they usually don't), it's that Twitter conversation can be manipulated just as easily as it can be used naturally. How will Twitter distinguish between positive Tweets coming from voters or news outlets and those from spam bots designed to drive the conversation surrounding a candidate one way or the other? How easy could it be for an organization with a vested interest in positive poll numbers for one candidate to craft an army of Twitter bots designed to drive Barack Obama's positive numbers down, or vice versa? How many people reading the data, which is sure to make its way to TV news as election coverage increases in the coming months, will be aware that Tweets can be manipulated?"

An anonymous reader writes "Research from Washington University in St. Louis has identified variations in brain scans that they believe identify portions of the brain that are responsible for intelligence (abstract). As suspected (and as explained by cartoons) brain size does play a small role; they said that brain size accounts for 6.7 percent of variance in intelligence. Recent research has placed the brain's prefrontal cortex, a region just behind the forehead, as providing for 5 percent of the variation in intelligence between people. The research from Washington University targets the left prefrontal cortex, and the strength of neural connections that it has to the rest of the brain. They think these differences account for 10 percent of differences in intelligence among people. The study is the first to connect those differences to intelligence in people."

First time submitter KateKintail writes "I'm being promoted to be a director of a computer/web services department at work with staff members (not yet hired) working under me. My workplace doesn't have a dress code 95% of the year. Is this the end of my days of jeans and enjoyably geeky t-shirts? Is there a way to dress professionally in the workplace as a boss (the kind that doesn't need to be defeated at the end of a level) while still showing my Browncoat or Whovian love as I crawl under cobwebby desks to check that equipment is properly plugged in?"

theodp writes "BetaBeat reports that people are pretty much falling over themselves to mock Apple's cheesy new Genius ad campaign, using zingers like 'intellectually cheap,' 'cringe-inducing,' 'borderline smarmy,' and — perhaps the unkindest cut of all — Microsoft-worthy — to describe them. Apple's trilogy-of-terror ad lineup includes Mayday ('An Apple Genius shows a fellow passenger how easy it is to make great home movies with iMovie. All before the tray tables are returned to their upright position.'), Labor Day ('An Apple Genius shows a soon-to-be father all the amazing things he can make with iPhoto.'), and Basically ('An Apple Genius points out there are a lot of things that separate a Mac from an ordinary computer, like great apps that come built in.'). The Atlantic's Jordan Weissmann says Steve Jobs would be appalled by the new ads, which certainly don't fare well in a head-to-head comparison with Think Different."

MojoKid writes with exciting news from AMD. From the article: "After more than six months of high-to-mid profile executive departures, AMD has major news to announce on its new executive hire — and he's a welcome addition. Starting today, Jim Keller will serve as a Vice President and the company's Chief Architect for CPU Cores. Keller has spent more than thirty years in the semiconductor business, including a few at AMD. When AMD brought members of DEC's Alpha team aboard in the late 1990s, Keller was one of the CPU architects that came along. Having worked on Alpha's EV5, Jim was lead architect on the first K8 project. Keller moved on and eventually became one of the core members of PA Semi which was bought by Apple in 2007."

DavidGilbert99 writes "NBC is the sole broadcaster of the London 2012 Olympics in the U.S., having paid $1.1bn for the privilege. While NBC is providing live streaming through its website, you need to have a valid cable subscription in order to view the events. This has seen many tech savvy U.S. viewers turning to proxy servers to view the BBC's Olympic coverage, which doesn't need any sign-in to view — once your IP address looks like it is coming from the UK. One provider of VPN services has seen a ten-fold increase in new customers signing up for their services since last Friday."
