Shuttle Reentry Over the Continental US 139

TheOtherChimeraTwin notes that the shuttle Discovery will land at Kennedy Space Center on Monday morning at 8:48 EDT. The craft will make a rare "descending node" overflight of the continental US en route to landing in Florida. Here are maps of the shuttle's path if is lands on orbit 222 as planned, or on the next orbit. Spaceweather.com says: "...it takes the shuttle about 35 minutes to traverse the path shown... Observers in the northwestern USA will see the shuttle shortly after 5 am PDT blazing like a meteoric fireball through the dawn sky. As Discovery makes its way east, it will enter daylight and fade into the bright blue background. If you can't see the shuttle, however, you might be able to hear it. The shuttle produces a sonic double-boom that reaches the ground about a minute and a half after passing overhead."

Disney Releases 3D Texture Mapper Source Code 83

dsavi writes "Ptex, Walt Disney Animation Studio's cutting-edge 3D texture mapping library which was first used on nearly every surface in the 2008 animated feature Bolt, was released under the BSD license on Friday. Quoting the announcement on monophyl.com: 'We expect to follow Ptex with other open source projects that we hope the community will find beneficial. We will soon be launching a new Walt Disney Animation Studios Technology page under disneyanimation.com. It will include links to our open source projects as will as a library of recent publications.' This looks good for open source 3D graphics."

The Psychology of Achievement In Playing Games 80

A post on Pixel Poppers looks at the psychological underpinnings of the types of challenges offered by different game genres, and the effect those challenges have on determining which players find the games entertaining. Quoting: "To progress in an action game, the player has to improve, which is by no means guaranteed — but to progress in an RPG, the characters have to improve, which is inevitable. ... It turns out there are two different ways people respond to challenges. Some people see them as opportunities to perform — to demonstrate their talent or intellect. Others see them as opportunities to master — to improve their skill or knowledge. Say you take a person with a performance orientation ('Paul') and a person with a mastery orientation ('Matt'). Give them each an easy puzzle, and they will both do well. Paul will complete it quickly and smile proudly at how well he performed. Matt will complete it quickly and be satisfied that he has mastered the skill involved. Now give them each a difficult puzzle. Paul will jump in gamely, but it will soon become clear he cannot overcome it as impressively as he did the last one. The opportunity to show off has disappeared, and Paul will lose interest and give up. Matt, on the other hand, when stymied, will push harder. His early failure means there's still something to be learned here, and he will persevere until he does so and solves the puzzle."

Jetman Attempts Intercontinental Flight 140

Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."

Brian Eno Releases Second iPhone App 196

Brian Eno, or as he is known to many in my office, "God," has released his second iPhone App. A followup to Bloom, this one is called Trope and supposedly creates darker music. You create music by drawing shapes on the iPhone's screen.

Comment Re:Zonk at Massively? (Score 5, Informative) 96

Aprils 17th was actually my last day with the site.

I'm just another Slashdot user now. :)

My primary gig is over at Massively, but I'm also writing at places like Wired, Gamasutra, and 1up.

As for stability, unfortunately I can't really speak to that. They're still very much in a Beta phase. It was a lot less glitchy than I've seen some games at that stage, but it was (of course) a setup specifically designed to give me the best impression of the game possible.

Comment Re:Iron Man's Suit Defies Physics -- Mostly (Score 2, Interesting) 279

Hydrogen peroxide powered rocket packs fly for around 30 seconds, because they have a specific impulse of around 125, meaning that one pound of propellant can make 125 pound-seconds of thrust, meaning that it takes about two pounds of propellant for every second you are in the air. Mass ratios are low for anything strapped to a human, so the exponential nature of the rocket equation can be safely ignored.

A pretty hot (both literally and figuratively) bipropellant rocket could manage about twice the specific impulse, and you could carry somewhat heavier tanks, but two minutes of flight on a rocket pack is probably about the upper limit with conventional propellants.

However, an actual jet pack that used atmospheric oxygen could have an Isp ten times higher, allowing theoretical flights of fifteen minutes or so. Here, it really is a matter of technical development, since jet engines have thrust to weight ratios too low to make it practical. There is movement on this technical front, but it will still take a while.

D&D 4th Edition Game System License Announced 131

Wizards of the Coast has announced plans for a brand-new system license for the fourth edition of Dungeons and Dragons . As with the d20 STL for Third Edition, this is a royalty-free license that will allow third parties to publish products using the rules developed by WotC. The new system reference document will be made available early in June (just after the release of the new edition). That license only covers fantasy gaming, but a second license (the d20 GSL) will be released allowing for any type of gaming product to be developed. For analysis and follow-up on the announcement, the ENWorld boards have full details.

Storm Dismantled at USENIX LEET Workshop 58

An anonymous reader writes "The USENIX LEET workshop held earlier this week in San Francisco offered neat insights into the Storm botnet, including two papers showing the difficulty of accurately measuring the botnet's size, and one on the way it conducts its spamming campaigns (down to the template language used). There was a bunch of other cool work too, so check out the papers."

AU Government Demands Universal Wiretapping 236

StonyandCher writes "The Australian government is pushing a bill to force all telecommunications providers to facilitate lawful data interception across fixed and mobile telephone systems, Voice over Internet Protocol (VoIP), Instant Messaging (IM) and chat room discussions. Sweeping reforms will make it easier than ever for law enforcement to intercept communications if amendments to the Telecommunications (Interceptions) Act are agreed upon by a Senate standing committee. This follows from a story earlier this week where the Australian government is legislating to allow employers to snoop on employees' email and IM conversations."

Thinkpad X300 With SSD Performance Evaluation 133

Ninjakicks writes "Hard drives are typically one of the more significant performance bottlenecks in any system today. An evaluation of Lenovo's new ultra portable Thinkpad X300 notebook shows a fast solid state hard drive can substantially improve the performance of a system. This is especially true of a low-end, low power processor and integrated graphics, in addition to reducing overall power consumption. Despite its 1.2GHz CPU the Thinkpad X300 is actually able to outperform some desktop replacement notebooks equipped with dual 7200RPM hard drives in RAID 0 in productivity benchmarks, and in data transfers. Interesting results, especially considering the X300's ultra portable form factor."

Google Earth 4.3 Offers a Number of New Features 133

GoogleWatch writes "Google's all excited for Earth day, and just in time there's a new version of Google Earth available. 4.3 offers up revamped navigation controls, 3-D photo-realistic buildings in major cities, and time-lapse views of sunsets and sunrises. Also new in Google Earth 4.3 is access to the street view movies found in Google Maps. Just click any of the camera icons and the familiar street view window will pop up. The sunrise and sunset movies are also quite impressive. Fly to a location you'd like to see and click the "sun" button in the toolbar. That will bring up a small timeline graphic and you can either hit play or drag the timeline slider to watch the day unfold."

Do the Blind Deserve More Effort on the Web? 663

dratcw writes "An article was posted this week to ComputerWorld, detailing the frustrations faced by blind people struggling to use the Web. The piece shows how little progress has been made and the inadequacy of solutions such as Microsoft's Narrator screen reader. While the article generated many positive comments, one reader said the disabled should 'get a grip' and maintained they 'have no more right to demand that others provide for their needs than I, as a diabetic, have a right to demand that sugar no longer be used.' Should Web sites and software makers do more, or does the reality of today's economics dictate that the blind/disabled will continue to struggle and learn to live with it?"

Japan's Cyborg Research Enters the Skull 120

RemyBR writes "Researchers at Osaka University are stepping up efforts to develop robotic body parts controlled by thought, by placing electrode sheets directly on the surface of the brain. The research marks Japan's first foray into invasive (i.e. requiring open-skull surgery) brain-machine interface research on human test subjects. The aim of the research is to develop real-time mind-controlled robotic limbs for the disabled. 'To date, the researchers have worked with four test subjects to record brain wave activity generated as they move their arms, elbows and fingers. Working with Advanced Telecommunications Research Institute International (ATR), the researchers have developed a method for analyzing the brain waves to determine the subject's intended activity to an accuracy of greater than 80%.'"
