Submission + - NVIDIA's Ninja Graphics Technology details leaked (

crazyeyes writes: There is a leak on NVIDIA's upcoming secret trick for their Kepler GPUs — the NVIDIA Ninja Graphics Technology . It claims to give NVIDIA gamers a random chance at evading bullets in FPS games through the manipulation of 3D primitives. Here's the key explanation :

"Normally, primitive data is converted to vertex points in 2D space before textures are applied and the scene is rendered. However, when an NVIDIA Kepler-based graphics card detects a game that supports Ninja Graphics, the GPU will automatically replicate an extra set of 3D primitive data for each frame and modify one copy with a random variable so that there are two slightly different primitives. The modified data will be sent back to the game, while the unmodified data sent to the vertex shaders and rendered normally.

Why do that at all? Well, the modified primitive data tricks the game into showing the player at a slightly different position in the game's world space. What this means is that the player appears slightly off to one side or another to other players (or the game's non-player characters) even though he is exactly where he's supposed to be. Perhaps this is why NVIDIA calls it Ninja Graphics — the player appears to be there, but isn't actually there."


Submission + - US nutter builds 350mph jet-powered school bus

oxide7 writes: Paul Stender and a team of engineers from the Indianapolis-based IndyBoys Inc fitted the yellow school bus with a jet engine from a Phantom fighter plane, allowing it to reach a frankly dangerous 367mph. That's 100mph more than the fastest car on the planet, the Bugatti Veyron Super Sports. All its seats, bar three, have been stripped out to decrease weight and improve the amount of usable power from its 42,000hp General Electric J-79 jet engine mounted at the rear.

Submission + - The myth of how the Great Depression was resolved (

cmarkn writes: The widespread belief is that government intervention is the key to getting the country out of a serious economic downturn. The example often cited is President Franklin D. Roosevelt's intervention, after the stock market crash of 1929 was followed by the Great Depression of the 1930s, with its massive and long-lasting unemployment.

This is more than just a question about history. Right here and right now there is a widespread belief that the unregulated market is what got us into our present economic predicament, and that the government must "do something" to get the economy moving again. FDR's intervention in the 1930s has often been cited by those who think this way.


Submission + - Why Being Wrong Makes Humans So Smart 1

Hugh Pickens writes: "Kathryn Schulz writes in the Boston Globe that the more scientists understand about cognitive functioning, the more it becomes clear that our capacity to make mistakes is utterly inextricable from what makes the human brain so swift, adaptable, and intelligent and that rather than treating errors like the bedbugs of the intellect — an appalling and embarrassing nuisance we try to pretend out of existence, we need to recognize that human fallibility is part and parcel of human brilliance. Neuroscientists increasingly think that inductive reasoning undergirds virtually all of human cognition. Humans use inductive reasoning to learn language, organize the world into meaningful categories, and grasp the relationship between cause and effect in the physical, biological, and psychological realms and thanks to inductive reasoning, we are able to form nearly instantaneous beliefs and take action accordingly. But our use of inductive reasoning comes with a price. "The distinctive thing about inductive reasoning is that it generates conclusions that aren’t necessarily true. They are, instead, probabilistically true — which means they are possibly false," writes Schulz. "Because we reason inductively, we will sometimes get things wrong." Schulz recommends that we respond to the mistakes (or putative mistakes) of those around us with empathy and generosity and demand that our business and political leaders acknowledge and redress their errors rather than ignoring or denying them. "Once we recognize that we do not err out of laziness, stupidity, or evil intent, we can liberate ourselves from the impossible burden of trying to be permanently right. We can take seriously the proposition that we could be in error, without deeming ourselves idiotic or unworthy.""
