Infinite Browser Universe Manyland Hits 8 Million Placed Blocks 67

j_philipp (803945) writes Manyland [Here's the twitter feed and a FAQ] is an HTML5 / JavaScript-based MMO universe created by a community and two indie developers from Europe. Everything in the world can be freely drawn and placed: From the cars, animals, plants, houses, bridges, to everyone's own bodies. Like Wikipedia, by default areas are editable by everyone (and removing a block leaves dust which can be used to undo the removal). Since the opening a year ago, over 100,000 different creations have been made, and now, over 8 million blocks placed. Some features are for logged-in users only, but the whole thing is free to explore for everyone, and it's just sucked away quite a few minutes for me.

Infected ATMs Give Away Millions of Dollars Without Credit Cards 83

An anonymous reader writes: Kaspersky Lab performed a forensic investigation into cybercriminal attacks targeting multiple ATMs around the world. During the course of this investigation, researchers discovered the Tyupkin malware used to infect ATMs and allow attackers to remove money via direct manipulation, stealing millions of dollars. The criminals work in two stages. First, they gain physical access to the ATMs and insert a bootable CD to install the Tyupkin malware. After they reboot the system, the infected ATM is now under their control and the malware runs in an infinite loop waiting for a command. To make the scam harder to spot, the Tyupkin malware only accepts commands at specific times on Sunday and Monday nights. During those hours, the attackers are able to steal money from the infected machine.

Infinite Crisis' Superhero Origins Story 50

An anonymous reader writes A new interview published this week looks at the creation of Infinite Crisis, one of the slew of Dota 2/League of Legends team multiplayer competitors currently under development. What makes this one stand out however is not only its use of DC Comics heroes like Batman and Wonder Woman, but the experience of the studio behind it, Turbine, in massively multiplayer online games and punishing abusive and toxic players, something League of Legends developer Riot has serious struggles with. Turbine was the studio behind the popular Asheron's Call, and is applying many of th same policing techniques it used in RPGs to the growing MOBA genre. Of course, they still have troubles with the inevitable: balancing Superman as a playable character. it's a challenge, Kerr admits, especially when you're having to nerf the Man of Steel as a result. "Yes, we redid Superman three times, because, and I know this is going to be a surprise, he was super overpowered," says Infinite Crisis creative director Cardell Kerr.

Tesla Removes Mileage Limits On Drive Unit Warranty Program 174

Ars Technica reports that Elon Musk today wrote that Tesla will remove mileage limits on its warranty policy for all Tesla Model S drive units. The warranty, which will still span eight years, won't have a cap on the number of owners for each vehicle. People who purchased Teslas before today were told that the warranty period for the drive unit expired after eight years or once the car logged over 125,000 miles. The revised warranty applies to new vehicles and Model S cars that are already on the road. The article mentions that quite a few Tesla owners have had to have their drive units replaced; out of warranty, that runs about $15,000. Musk's announcement acknowledges that the change may cost the company some money, but says he's "confident it will work out well in the long run."

Building the Infinite Digital Universe of No Man's Sky 100

An anonymous reader writes: Hello Games is a small development studio, only employing 10 people. But they're building a game, No Man's Sky, that's enormous — effectively infinite. Its universe is procedurally generated, from the star systems down to individual species of plant and animal life. The engine running the game is impressively optimized. A planet's characteristics are not computed ahead of time — terrain and lifeforms are randomly generated on the fly as a player explores it. But, of course, that created a problem for the developers — how do they know their procedural generation algorithms don't create ridiculous life forms or geological formations? They solved that by writing AI bot software that explores the universe and captures brief videos, which are then converted to GIF format and posted on a feed the developers can review. The article goes into a bit more detail on how the procedural generation works, and how such a small studio can build such a big game.

Understanding an AI's Timescale 189

An anonymous reader writes "It's a common trope in sci-fi that when AIs become complex enough to have some form of consciousness, humans will be able to communicate with them through speech. But the rate at which we transmit and analyze data is infinitesimal compared to how fast a computer can do it. Would they even want to bother? Jeff Atwood takes a look at how a computer's timescale breaks down, and relates it to human timeframes. It's interesting to note the huge variance in latency. If we consider one CPU cycle to take 1 second, then a sending a ping across the U.S. would take the equivalent of 4 years. A simple conversation could take the equivalent of thousands of years. Would any consciousness be able to deal with such a relative delay?"

Is There a Limit To a Laser's Energy? 135

StartsWithABang (3485481) writes "For normal matter — things like protons, neutrons and electrons — there's a fundamental limit to the number of particles you can fit into a given region of space thanks to the Pauli exclusion principle. But photons aren't subject to that limit; in theory, you could cram an infinite number of them into the same exact state. In principle, then, couldn't you create a laser (or lasing cavity) with an infinite amount of energy inside? Perhaps, but there are some big challenges to be overcome!"

Bug Bounties Don't Help If Bugs Never Run Out 235

Bennett Haselton writes: "I was an early advocate of companies offering cash prizes to researchers who found security holes in their products, so that the vulnerabilities can be fixed before the bad guys exploited them. I still believe that prize programs can make a product safer under certain conditions. But I had naively overlooked that under an alternate set of assumptions, you might find that not only do cash prizes not make the product any safer, but that nothing makes the product any safer — you might as well not bother fixing certain security holes at all, whether they were found through a prize program or not." Read on for the rest of Bennett's thoughts.

Einstein's Lost Model of the Universe Discovered 'Hiding In Plain Sight' 118

Hugh Pickens DOT Com writes "Dick Ahlstrom reports that Irish researchers have discovered a previously unknown model of the universe written in 1931 by physicist Albert Einstein that had been misfiled and effectively "lost" until its discovery last August while researchers been searching through a collection of Einstein's papers put online by the Hebrew University in Jerusalem. "I was looking through drafts, but then slowly realised it was a draft of something very different," says Dr O'Raifeartaigh. "I nearly fell off my chair. It was hidden in perfect plain sight. This particular manuscript was misfiled as a draft of something else." Read more, below.

Game Tech: How BioShock Infinite's Lighting Works 55

An anonymous reader writes "The Principal Graphics Programmer for BioShock Infinite has put up a post about how the game's lighting was developed. We don't usually get this kind of look into the creation of AAA game releases, but the studio shut down recently, so ex-employees are more willing to explain. The game uses a hybrid lighting system: direct lighting is dynamic, indirect uses lightmaps, shadows are a mix. 'Dynamic lighting was handled primarily with a deferred lighting/light-pre pass renderer. This met our goals of high contrast/high saturation — direct lighting baked into lightmaps tends to be flat, mostly because the specular approximations available were fairly limited.' It's interesting how much detail goes into something you don't really think about when you're playing through the game. 'We came up with a system that supported baked shadows but put a fixed upper bound on the storage required for baked shadows. The key observation was that if two lights do not overlap in 3D space, they will never overlap in texture space. We made a graph of lights and their overlaps. Lights were the vertices in the graph and the edges were present if two lights' falloff shapes overlapped in 3D space. We could then use this graph to do a vertex coloring to assign one of four shadow channels (R,G,B,A) to each light. Overlapping lights would be placed in different channels, but lights which did not overlap could reuse the same channel. This allowed us to pack a theoretically infinite number of lights in a single baked shadow texture as long as the graph was 4-colorable.'"

A Mathematical Proof Too Long To Check 189

mikejuk writes "Mathematicians have generally gotten over their unease with computer-assisted proofs. But in the case of a new proof from researchers at the University of Liverpool, we may have crossed a line. The proof is currently contained within a 13 GB file — more space than is required to hold the entirety of Wikipedia. Its size makes it unlikely that humans will be able to check and confirm the proof. The theorem that has been proved is in connection with a long running conjecture of Paul Erdos in 1930. Discrepancy theory is about how possible it is to distribute something evenly. It occurs in lots of different forms and even has a connection with cryptography. In 1993 it was proved that an infinite series cannot have a discrepancy of 1 or less. This proved the theorem for C=1. The recent progress, which pushes C up to 2, was made possible by a clever idea of using a SAT solver — a program that finds values that make an expression true. Things went well up to length 1160, which was proved to have discrepancy 2, but at length 1161 the SAT returned the result that there was no assignment. The negative result generated an unsatisfiability certificate: the proof that a sequence of length 1161 has no subsequence with discrepancy 2 requires over 13 gigabytes of data. As the authors of the paper write: '[it]...is probably one of longest proofs of a non-trivial mathematical result ever produced. ... one may have doubts about to which degree this can be accepted as a proof of a mathematical statement.' Does this matter? Probably not — as long as other programs can check the result and the program itself has to be considered part of the proof."

Why Improbable Things Really Aren't 166

First time accepted submitter sixoh1 writes "Scientific American has an excellent summary of a new book 'The Improbabilty Principle: Why Coincidences, Miracles, and Rare Events Happen Every Day' by David J. Hand. The summary offers a quick way to relate statistical math (something that's really hard to intuit) to our daily experiences with unlikely events. The simple equations here make it easier to understand that improbable things really are not so improbable, which Hand call the 'Improbability Principle:' 'How can a huge number of opportunities occur without people realizing they are there? The law of combinations, a related strand of the Improbability Principle, points the way. It says: the number of combinations of interacting elements increases exponentially with the number of elements. The 'birthday problem' is a well-known example. Now if only we could harness this to make an infinite improbability drive!"

Major Advance Towards a Proof of the Twin Prime Conjecture 248

ananyo writes "Researchers hoping to get '2' as the answer for a long-sought proof involving pairs of prime numbers are celebrating the fact that a mathematician has wrestled the value down from infinity to 70 million. That goal is the proof to a conjecture concerning prime numbers. Primes abound among smaller numbers, but they become less and less frequent as one goes towards larger numbers. But exceptions exist: the 'twin primes,' which are pairs of prime numbers that differ in value by 2. The twin prime conjecture says that there is an infinite number of such twin pairs. Some attribute the conjecture to the Greek mathematician Euclid of Alexandria, which would make it one of the oldest open problems in mathematics. The new result, from Yitang Zhang of the University of New Hampshire in Durham, finds that there are infinitely many pairs of primes that are less than 70 million units apart. He presented his research on 13 May to an audience of a few dozen at Harvard University in Cambridge, Massachusetts. Although 70 million seems like a very large number, the existence of any finite bound, no matter how large, means that that the gaps between consecutive numbers don't keep growing forever."

AMD Radeon HD 7990 Released: Dual GPUs and 6G of Memory for $1000 189

An anonymous reader writes "Today AMD has officially unveiled its long-awaited dual-GPU Tahiti-based card. Codenamed Malta, the $1,000 Radeon HD 7990 is positioned directly against Nvidia's dual-GPU GeForce GTX 690. Tom's Hardware posted the performance data. Because Fraps measures data at a stage in the pipeline before what is actually seen on-screen, they employed Nvidia's FCAT (Frame Capture Analysis Tools). ... The 690 is beating AMD's new flagship in six out of eight titles. ... AMD is bundling eight titles with every 7990, including: BioShock Infinite, Tomb Raider, Crysis 3, Far Cry 3, Far Cry 3: Blood Dragon, Hitman: Absolution, Sleeping Dogs, and Deus Ex: Human Revolution." OpenGL performance doesn't seem too off from the competing Nvidia card, but the 7990 dominates when using OpenCL. Power management looks decent: ~375W at full load, but a nice 20W at idle (it can turn the second chip off entirely when unneeded). PC Perspective claims there are issues with Crossfire and an un-synchronized rendering pipeline that leads to a slight decrease in the actual frame rate, but that should be fixed by an updated Catalyst this summer.

The Dark Side of Amazon's New Pilots 312

I've been really, really excited about digital video distribution lately: first Netflix greenlights jms's return to science fiction TV, and then Amazon announces their new pilots. Perhaps the decade long dearth of any good television is nearing its end! So, with that in mind, I finished up editing Slashdot for the day and sat down to watch some of these new pilots. Only to discover that Amazon has taken away my ability to watch entirely in the name of Digital Restrictions Management.

AMD Reveals Radeon Sky Series For Cloud Gaming, Previews Radeon HD 7990 53

MojoKid writes "AMD made a number of interesting announcements today at the Game Developers Conference, currently taking place in San Francisco. AMD revealed their 'Radeon Sky' series of graphics products targeted at cloud gaming and virtualized computing applications. The company also showed off the dual-GPU powered AMD Radeon HD 7990, and extended the 'Never Settle: Reloaded' gaming bundle program to include BioShock Infinite. AMD revealed three Radeon Sky Series cards, two based on the Tahiti GPU and another based on Pitcairn. The top of the line Radeon Sky 900 is powered by two Tahiti GPUs linked to 6GB of memory (3GB per GPU). The Sky 700 is powered by a single Tahiti GPU and the Sky 500 is based on Pitcairn. All of the cards are passively cooled and are designed for cloud gaming / computing servers. The upcoming high-end, consumer targeted Radeon HD 7990 was also previewed, but few details were given. Devon Nekechuk, Product Manager of AMD Graphics, did say the triple-fan setup was whisper quiet. We think it's safe to assume the card features 6GB of memory and clocks are in-line with current Radeon HD 7970 GHz Edition cards."

BioShock: Infinite Released 149

kandelar writes with news that BioShock: Infinite has been released. It's the third major release in the series of BioShock first-person shooters, and it's available for Xbox 360, PS3, and Windows. The game is garnering good critical reception, for the most part. Rock, Paper, Shotgun said, "Infinite is a game ruled by artists at least as much as it is by its writers. It’s the ultimate answer to the question of whether art or technology is the most important part of creating a visually excellent game – Crysis 3 might have far more going on under the hood, but its uninspired paintjob makes it seem so dull compared to Infinite’s vaguely Pixar-esque fusion of the photoreal and the colourfully unreal." Ars' reviewer wrote, "Infinite's battle system doesn't wear out its welcome or weigh down the game's excellent pacing. Infinite avoids the problem of near-endless waves of identical enemies that plagues so many shooters these days. The bits of shooting action are spaced and timed to serve as gentle punctuation marks that break up the story rather than full stops that bring it to a grinding halt." However, RPS adds this criticism of the player's effect the plot: "Infinite’s a triumph in terms of fantasy-architecture spectacle and bringing superb flexibility to the modern rollercoaster shooter, but in other respects it’s a small step down from the player agency and even the singular aesthetic of BioShock."

Apple: 75% of Our World Wide Power Needs Now Come From Renewable Power Sources 262

skade88 writes "Apple now owns and runs enough renewable energy power plants that 75% of their world wide power needs come from renewable sources such as wind, solar, geothermal and hydro. From the Apple Blog Post: 'Our investments are paying off. We've already achieved 100 percent renewable energy at all of our data centers, at our facilities in Austin, Elk Grove, Cork, and Munich, and at our Infinite Loop campus in Cupertino. And for all of Apple's corporate facilities worldwide, we're at 75 percent, and we expect that number to grow as the amount of renewable energy available to us increases. We won't stop working until we achieve 100 percent throughout Apple.'"
