Alva Noe: Don't Worry About the Singularity, We Can't Even Copy an Amoeba 455

An anonymous reader writes "Writer and professor of philosophy at the University of California, Berkeley Alva Noe isn't worried that we will soon be under the rule of shiny metal overlords. He says that currently we can't produce "machines that exhibit the agency and awareness of an amoeba." He writes at NPR: "One reason I'm not worried about the possibility that we will soon make machines that are smarter than us, is that we haven't managed to make machines until now that are smart at all. Artificial intelligence isn't synthetic intelligence: It's pseudo-intelligence. This really ought to be obvious. Clocks may keep time, but they don't know what time it is. And strictly speaking, it is we who use them to tell time. But the same is true of Watson, the IBM supercomputer that supposedly played Jeopardy! and dominated the human competition. Watson answered no questions. It participated in no competition. It didn't do anything. All the doing was on our side. We played Jeopordy! with Watson. We used 'it' the way we use clocks.""

The Most Expensive One-Byte Mistake 594

An anonymous reader writes "Poul-Henning Kamp looks back at some of the bad decisions made in language design, specifically the C/Unix/Posix use of NUL-terminated text strings. 'The choice was really simple: Should the C language represent strings as an address + length tuple or just as the address with a magic character (NUL) marking the end? ... Using an address + length format would cost one more byte of overhead than an address + magic_marker format, and their PDP computer had limited core memory. In other words, this could have been a perfectly typical and rational IT or CS decision, like the many similar decisions we all make every day; but this one had quite atypical economic consequences.'"

Are Consoles Holding Back PC Gaming? 518

An anonymous reader writes "Despite all the excitement over Nvidia's upcoming Fermi GPU, there is still a distinct lack of DirectX 11 games on the market. This article points out that while the PC has returned to favor as a gaming platform, consoles are still the target for most developers, and still provide the major limitations on the technological sophistication of game graphics. Inside the Xbox 360 sits an ATI Xenos GPU, a DirectX 9c-based chip that bears similarity to the Radeon X1900 series of graphics cards (cards whose age means that they aren't even officially supported in Windows 7). Therein lies the rub. With the majority of PC games now starting life as console titles, games are still targeted at five-year-old DirectX 9 hardware."

Bittorrent To Cause Internet Meltdown 872

Gimble writes "Richard Bennett has an article at the Register claiming that a recent uTorrent decision to use UDP for file transfers to avoid ISP 'traffic management' restrictions will cause a meltdown of the internet reducing everybody's bandwidth to a quarter of their current value. Other folks have also expressed concern that this may not be the best thing for the internet."

Inside the World's Most Advanced Planetarium 133

notthatwillsmith writes "Earlier this month, the most technologically-advanced digital planetarium in the world opened in San Francisco's California Academy of Sciences. The new Morrison Planetarium's 75-foot screen replaces the traditional Zeiss projector with an array of 6 high-resolution DLP projectors arrayed around the edge of the theater, which are powered by three very different, but interesting computing clusters. The three clusters allow for projection of traditional planetarium shows, playback of ultra-high resolution movies, and display of anything from current atmospheric conditions on Earth to a (greatly accelerated) trip to the farthest reaches of the universe, all rendered in real-time on an 8800 sq. ft. dome. Maximum PC went on a behind the scenes tour with the engineers who built the systems that do everything from run the planetarium lights to the sound systems to the tech behind the screen to show you how it works and what it's like to drive, well ... the universe."
