Comment Re:Lots of evidence for higher frame rates (Score 1) 521

I'm surprised that as an ex-LED-backlight designer, you state:

The reason I say 'the only good way' is because LED's are constant-current devices and all the drivers I'm familiar with are all designed around that, so you can't just go varying the voltage to try and dim them: the drivers aren't really voltage devices.

LED are Light Emitting Diodes. Diodes function as a switch- once you reach and surpass the 'turn on' voltage, the brightness of the diode remains constant. The only option is to apply the voltage to the diode as a wave.

Try it. Block the outbound port connecting to Steam. What? You mean you can't play your game without phoning home? I thought if the servers were taken offline, you could play?
Never rely on a promise to protect your rights. For all you know, they could go under, get sold to a new owner in bankruptcy court and the new owner could shut off the servers but not give up the licenses.

Shockingly wrong. You can invoke your right to not self-incriminate on a question by question basis. Otherwise, stating your name for the record would be waiving your 5th amendment right. Granted, I don't disagree with being compelled to give up encrypted files. I think a better comparison is showing them the shed where the bodies are buried, then refusing to give them the key. In this case, the cops can't use bolt cutters, so it is reasonable to compel you to provide the files.

Falcon 9 Is Now Fully Integrated At Cape Canaveral 82

RobGoldsmith writes "SpaceX's Falcon 9 is now fully integrated: an update from Elon Musk states 'Falcon 9 is now fully integrated at the Cape! Today we mated the 5.2 m payload fairing to the Falcon 9 first stage. This was the final step in the integration process — one day ahead of schedule.' New images are now available showing the first fully integrated Falcon 9 Rocket. Once the launch mount and erector are complete, SpaceX will transfer Falcon 9 on to the erector and raise it to vertical early in 2009."

Comment Why Patrick Moore left Greenpeace (Score 2, Informative) 271

This kind of garbage is why Patrick Moore, one of the Greenpeace founders, left the movement. "By the mid-1980s, the environmental movement had abandoned science and logic in favor of emotion and sensationalism. I became aware of the emerging concept of sustainable development: balancing environmental, social and economic priorities. Converted to the idea that win-win solutions could be found by bringing all interests together, I made the move from confrontation to consensus."

The Question of Robot Safety 482

An anonymous reader writes to mention an Economist article wondering how safe should robots be? From the article: "In 1981 Kenji Urada, a 37-year-old Japanese factory worker, climbed over a safety fence at a Kawasaki plant to carry out some maintenance work on a robot. In his haste, he failed to switch the robot off properly. Unable to sense him, the robot's powerful hydraulic arm kept on working and accidentally pushed the engineer into a grinding machine. His death made Urada the first recorded victim to die at the hands of a robot. This gruesome industrial accident would not have happened in a world in which robot behavior was governed by the Three Laws of Robotics drawn up by Isaac Asimov, a science-fiction writer." The article goes on to explore the ethics behind robot soldiers, the liability issues of cleaning droids, and the moral problems posed by sexbots.

First 802.11n Products Breaking Out 105

capt turnpike writes "If you're hooked up to a fat pipe, but want mobility, it looks like the new 802.11n standard might have some promise. eWEEK.com got their hands on some of the upcoming products and put the new devices through their paces." From the article: "The 802.11n task group is aware of the current draft's issues with legacy wireless LAN devices (specifically with how 802.11n shares bandwidth with attached legacy clients), and representatives from Cisco and Motorola broke off to look into the issues before the next meeting of the draft subcommittee, which is scheduled for May. Expectations vary widely, depending on whom you talk to. In previous conversations with Dave Borison, Airgo's director of product marketing, we leaned that Airgo is not making chip sets based on the draft standard because the company thinks the issue of legacy interoperability is significant enough to necessitate small modifications to the silicon."
