...but if you want a spiritual experience that's less dangerous than cutting your head open or reading the Bible, then I highly recommend ingesting 10 grams of Psilocybin Mushrooms - completely natural and non-toxic - skeptic or not, I recommend every sane, creative or intelligent person give them a go!

Brain Surgery Linked To Sensation of Spirituality 380

Posted by timothy from the applied-psychology dept.
the3stars writes "'Removing part of the brain can induce inner peace, according to researchers from Italy. Their study provides the strongest evidence to date that spiritual thinking arises in, or is limited by, specific brain areas. This raises a number of interesting issues about spirituality, among them whether or not people can be born with a strong propensity towards spirituality and also whether it can be acquired through head trauma." One critic's quoted response: "It's important to recognize that the whole study is based on changes in one self-report measure, which is a coarse measure that includes some strange items."

Code Review of Doom For the iPhone 161

Posted by Soulskill from the old-dogs-new-tricks dept.
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...)."
