  1. Re:Sigh... on "Cumulative Voting" Method Gaining Attention · · Score: 1

    The root problem behind the unsatisfiability of all voting criteria is the attempt to contradict something simple and obvious: a population cannot have a preference, only an individual can. There is no reasonable way to define the concept of a preference for a population. Voting systems are sleights of hand that try to hide this basic truism.

    What a ludicrous comment. The newer cards are not there to offer faster performance, but new features (OpenGL 4.0 / DirectX 11), and specifically, tessellation, which is a feature sorely needed in the world of horribly low-polygon count models that plague every 3D game out there. There are also various other GL/DX features that require hardware support and will become commonplace in upcoming games.

    Special-purpose computers are making a comeback. See for example Anton, the molecular dynamics simulator. It's about two orders of magnitude faster at what it does than general purpose supercomputers. Quantum computers might turn out to, at least initially, be most useful in this sort of application.

    This issue was solved in Brightside's HDR display, the first to use LED modulation several years ago. LEDs are addressed individually, so the locality is very low. Also, the brightness achievable is much higher (though the unit drew 1500 Watts for the large screen version); i.e. individual areas on the screen could be made as bright as looking at a light bulb. The reason locality wasn't an issue is that the few dozen pixel-sized areas lit by a given LED are small enough to provide higher dynamic range than the *local* dynamic range the human eye can muster. While the eye has a huge dynamic range, that is not the case over a small portion of the field of view. The downside of Brightside's stuff (later acquired by Adobe) is the energy usage needed to get really high brightness through an LCD display, where the best LCDs will at most let through 6% of the light. The LED array in the back had huge heatsinks and active cooling; they put out several times the luminance of a regular display's backlight. That, and he cost of the damn thing... In the end we won't see practical HDR displays for sale to average consumers until something like OLEDs become cheap enough for mass market.

    Morals are not purely arbitrary and generalize to an extent across humanity, due to shared evolutionary psychology. There are plenty of differences and variations, but there's no doubt that if you perform cluster analysis akin to what A.W.F. Edwards did for human racial genetic diversity in the "Lewontin's Fallacy" paper, you will see that overall it our morals form a clear locus in phase space. Thus, those individuals or small groups that significantly deviate from the overall can truly be regarded as outliers and their view treated as such--inappropriate, morally _wrong_. Relativism may make sense in idealistic terms, but in practice it assumes a very broad statistical distribution of moral parameters across the population, which is bullshit.

Paper & free code for the GI solution: http://graphics.cs.williams.edu/papers/PhotonHPG09/ The engine it's implemented in: http://g3d.sourceforge.net/ One cannot say that closed-source leads the pack across the scape of graphical features. Another example besides this level of RT GI is spherical-blend skinning, which was in open source first as well. I'm sure others can point out other advances that come from the open source world.

  19. Re:If anything comes of this... on New "Wet Computer" To Mimic Neurons In the Brain · · Score: 1

    Your comment doesn't make sense. Even neuroscientists (as opposed to computer scientists) will tell you that the type of process, electrochemical vs any other, has no impact on the ultimate information processing ability, which can be abstracted from the process which is but mere mode of implementation. A sufficiently complex biological or chemical computer will be Turing-complete, just like an electrical computer, and _can be no more_ powerful--just more or less efficient at various tasks in terms of time or energy or whatever. No one working with neurons has any illusion that the information processing of the neurons indelibly depends on electrochemical actions; the same information processing can be replicated by any other process such as mechanical, electronic, or whatnot. Saying that "thought is only an electrochemical process" is doubly misleading because 1) it implies that the complexity of though have to do with electrochemical reactions when the correct level of abstractions is information processing, and 2) because it implies that only electrochemical processes can represent thought.

    SDL has a number of problems and we've dropped it from our projects. It is definitely not performance oriented; for example, calls to WaitForSingleObject in the Windows port even when it can be determined that no blocking is necessary, and thus wasting 4000 cycles on a kernel call instead of 200 on an interlocked instruction. That's just one random example that came up when we were troubleshooting performance. Note that I'm not at all ranting against using other libraries, and I'm generally sour to DirectX. It's just that SDL is a mediocre example for anything other than input handling. For threading, pthreads works great for both Linux and Windows (the Windows port is much better optimized than SDL threads), or even better yet from a software engineering perspective, boost threads can be used. In a high performance optimized to a given engine architecture, a custom thread library with custom task scheduling etc. is the real choice, and would written at a lower level than these libraries, with OS primitives and interlocked instructions. With networking, there is a huge amount of libraries out there that are optimized for various tasks better than SDL Net, and for sound OpenAL is the obvious choice (using libavcodec/ffmpeg for decoding).
