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...)."

Hugh Pickens writes "Doug Feaver has an interesting story in the Washington Post 'in defense of the anonymous, unmoderated, often appallingly inaccurate, sometimes profane, frequently off point and occasionally racist reader comments that washingtonpost.com allows to be published at the end of articles and blogs.' Feaver says that during his seven-year tenure as editor and executive editor of washingtonpost.com he kept un-moderated comments off the site, but now, four years after retiring, he says he has come to think that online comments are a terrific addition to the conversation, and that journalists need to take them seriously. 'The subjects that have generated the most vitriol during my tenure in this role are race and immigration,' writes Feaver. 'But I am heartened by the fact that such comments do not go unchallenged by readers. In fact, comment strings are often self-correcting and provide informative exchanges.' Feaver says that comments are also a pretty good political survey. 'The first day it became clear that a federal bailout of Wall Street was a real prospect, the comments on the main story were almost 100 percent negative. It was a great predictor of how folks feel, well out in front of the polls. We journalists need to pay attention to what our readers say, even if we don't like it. There are things to learn.'"

andremachado writes "Two academic management researchers, Siobhán O'Mahony and Fabrizion Ferraro, performed a detailed scientific study about Debian Project governance and social organization from the management perspective. How did a big non-commercial non-paying community evolve to produce some of the most respectable Operating Systems and applications packages available? Organizations without a consensual basis of authority lack an important condition necessary for their survival. Those with directly democratic forms of participation do not tend to scale well and are noted for their difficulty managing complexity and decision-making — all of which can hasten their demise. The Debian Project community designed and evolved a solid governance system since 1993 able to establish shared conceptions of formal authority, leadership, and meritocracy, limited by defined democratic adaptive mechanisms."
