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...)."

Gamasutra reports on comments from Stardock CEO Brad Wardell in which he described his efforts to revive two old but popular franchises: Star Control and Master of Orion. Quoting: "'I actually pitched Atari on a whole idea for a true successor to Star Control,' [he said], noting that the game would follow original series developer Toys for Bob's Star Control II rather than the Legend Entertainment-developed Star Control 3 ('We just pretend that never happened,' the CEO says of that release). ... Novato, California-based Toys for Bob has actually floated the idea of making its own Star Control II sequel, with co-creator Paul Reiche III indicating he has tossed potential design ideas around, but with the company now owned by publisher Activision the proposal seems to be stuck in limbo."

p1234 writes with this excerpt from the Max Planck Institute for Astrophysics: "Simulations by the Virgo team show how the Milky Way's halo grew through a series of violent collisions and mergers from millions of much smaller clumps that emerged from the Big Bang. ... If Fermi does detect the predicted emission from the Milky Way's smooth inner halo, then it may, if we are lucky, also see gamma-rays from small (and otherwise invisible) clumps of dark matter which happen to lie particularly close to the Sun. ... The largest simulation took 3.5 million processor hours to complete. Volker Springel was responsible for shepherding the calculation through the machine and said: 'At times I thought it would never finish.' Max Planck Director, Professor Simon White, remarked that 'These calculations finally allow us to see what the dark matter distribution should look like near the Sun where we might stand a chance of detecting it.'" We discussed a related simulation a few months ago.

blackbearnh wrote in with a story that's not really about the iPhone, but if your office speakerphones beep like mine does, read on: "If you own an iPhone, you may have noticed that it has a distinct and very annoying effect on clock radios, computer speakers, car radios, and just about anything else with a speaker. The folks at O'Reilly Media aren't immune, so they set out to discover just what is it about iPhones that makes them such bad RF citizens. The iPhones aren't the only bad apples in the cell phone basket and there's not much you can do about the problem. We're really in an interesting time in that there has never been so many high-powered personal transmitters just wandering loose in the world."

An anonymous reader writes "InfoWeek blogger Alex Wolfe put together a scorecard which makes the obvious but interesting point that, when you list every major DRM technology implemented to "protect" music and video, they've all been cracked. This includes Apple's FairPlay, Microsoft's Windows Media DRM, the old-style Content Scrambling System (CSS) used on early DVDs and the new AACS for high-definition DVDs. And of course there was the Sony Rootkit disaster of 2005. Can anyone think of a DRM technology which hasn't been cracked, and of course this begs the obvious question: Why doesn't the industry just give up and go DRM-free?"
