An article at Wired discusses the difficulties involved in transferring games that were purchased and downloaded online when users replace their Wii or DSi. "Neither the Wii nor Nintendo’s portable DSi consoles have an upgrade path for downloadable content, since games are tied not to user accounts but to specific machines. It’s impossible for a user to copy content from an old console to a new one. Even some Wii owners whose machines have malfunctioned said it was difficult, or impossible, to get Nintendo to transfer the software licenses at its headquarters." One gamer, who bought the recently released black Wii console, explained that she got Nintendo to transfer her games, but needed to "mail both of her Wii consoles to Nintendo, and wait two weeks," hardly a convenient solution.

Cytotoxic writes "What to do with all of those leftover Valentine's Day chocolates? — a common problem for the Slashdot crowd. The folks over at Wired magazine have an answer for you in a nice article showing how to measure the speed of light with a microwave and some chocolate. A simple yet surprisingly accurate method that can be used to introduce the scientific method to children and others in need of a scientific education."

Developer Fabien Sanglard has written a code review for id Software's iPhone port of Doom. It's an interesting look into how the original 1993 game (which he also reviewed to understand its rendering process) was adapted to a modern platform. "Just like Wolfenstein 3D, Doom was rendering a screenframe pixel per pixel. The only way to do this on iPhone with an acceptable framerate would be to use CoreSurface/CoreSurface.h framework. But it is unfortunately restricted and using it would prevent distribution on the AppStore. The only solution is to use OpenGL, but this comes with a few challenges: Doom was faking 3D with a 2D map. OpenGL needs real 3D vertices. More than 3D vertices, OpenGL needs data to be sent as triangles (among other things because they are easy to rasterize). But Doom sectors were made of arbitrary forms. Doom 1993's perspective was also faked, it was actually closer to an orthogonal projection than a perspective projection. Doom was using VGA palette indexing to perform special effect (red for damage, silver for invulnerable...)."

An anonymous reader points out an article at SavyGamer in which several game industry veterans were polled for their opinions on DRM. Cliff Harris of Positech Games said he didn't think his decision to stop using DRM significantly affected piracy of his games, accepting it as an unavoidable fact. "Maybe a few of the more honest people now buy the game rather than pirate it, but this sort of thing is impossible to measure. You can see how many people are cracking and uploading your game, but tracking downloads is harder. It seems any game, even if it's $0.99 has a five hour demo and is DRM-free and done by a nobel-peace prize winning game design legend, will be cracked and distributed on day one by some self righteous teenager anyway. People who crack and upload games don't give a damn what you've done to placate gamers, they crack it anyway." Nihal de Silva of Direct2Drive UK said his company hasn't noticed any sales patterns indicating customers are avoiding games with DRM. Richard Wilson of TIGA feels that customers should be adequately warned before buying a game that uses DRM, but makes no bones about the opinion that the resale of used games is not something publishers should worry about.

longacre writes "An amateur video of the 1986 Space Shuttle Challenger explosion has been made public for the first time. The Florida man who filmed it from his front yard on his new Betamax camcorder turned the tape over to an educational organization a week before he died this past December. The Space Exploration Archive has since published the video into the public domain in time for the 24th anniversary of the catastrophe. Despite being shot from about 70 miles from Cape Canaveral, the shuttle and the explosion can be seen quite clearly. It is unclear why he never shared the footage with NASA or the media. NASA officials say they were not aware of the video, but are interested in examining it now that it has been made available."

cheros writes "NASA reports that the Spirit Mars lander is presently stuck in soft soil. The lander's wheels are halfway sunk into the soil and they are planning simulation tests to see if they can get it out again. I hope they can get it out of there because it's picking up enough new energy to operate; however, it only has 5 wheels left to get around on — one of the wheels hasn't been working for years. Fingers crossed."
