### Elo Chess Rating System Topped By Proposed Replacements

I am not quite certain that I follow. Depending on tournament type R/P/S is (mostly) a game of chance, chess isn't. The only way I can see R/P/S applying is if they represent the players themselves, not the game. In other words, instead of having individual strength ratings that can be measured in isolation, player R's style of play might be naturally stronger against player S's style than that of player P, in which case we could only express the relative strengths of any pairing. This would allow a scenario where R is stronger than S is stronger than P is stronger than R.

However, given the pairing list of a tournament and the respective pairwise relative strengths, it is still possible to predict the outcome. As a very simple example, let's say that on the first round we have the pairs (rock_a, paper) and (rock_b, scissors). Winners of the first round (paper, rock_b) fight for gold, losers (rock_a, scissors) for bronze. Paper wins, followed by rock_a, rock_b takes bronze and leaves scissors last.

Applied to the problem at hands, one would suspect that there exists an algorithm not far removed from Google's PageRank that can identify all the possible playstyles and their relative strengths, in which case the simplest predictive model would contain the playstyle preference and proficiency of the players combined with style coupling constants (it is likely that a player can play several styles with varying degree of skill, and try to use the one that they believe to give them the best chances against what they know of their opponent). Just my hunch, I'm not really into this stuff.

### Hubble In Anaglyph Stereo 3D

Re:I am color blind. Can I see the stereo 3-D movi (114 comments)

I am color blind, lacking the ability to see red light. The red-cyan glasses don't work for me because from my point of view the red lens is completely opaque (black) and the cyan lens completely translucent (clear). Thus, you could simulate my experience with the glasses by covering your left eye with your hand and watching the movie with your right eye only. It's not exactly an improvement ...

### Why UNIX is better than Windows... By Microsoft

Read the paper - pretty reasonable stuff. The only thing that may raise eyebrows is the origin of the paper. Goes to show that Microsoft has some competent people working for them (did anybody doubt that, it's after all the company policy that is rotten) but also a horde of absolutely brilliant PR weasels which can turn black to white when you're not watching.
