The best game I've played so far this year is Uncharted, followed by Bioshock and Mass Effect. Portal is amazing, but a bit too short to justify GOTY IMO.
Please forgive my ignorance (and the somewhat off-topic nature of this post), but why is it that everyone hates Roland so much? It may be totally legitimate, but I guess I haven't read enough of his posts to see why he is so odious. Does he only post to get traffic for his site? Is he an arrogant asshat? Why the "rolandsucks" and "boycottroland" tags? I just remember that last time I was a Roland post, the tagging also had the anti-roland phrases. Anyone care to enlighten me (in a somewhat objective manner?) Thank you.
"Now that GTA and MGS are not going to be exclusive..."
Has it been confirmed that MGS is no longer an exclusive? GTA going multiplatform is old news, but I was under the impression that MGS was still a PS3-only game. Do you have a link I could look at?
Halon is Dichlorodifluoromethane (CCl2F2) -->a chlorofluorocarbon (CFC...) It's also known as Freon-12 and Arcton and it's low BP (-30 deg C) makes it a good refrigerant..................... Also, as I understand it, CFC's are banned globally and have been replaced generally with CFHC's (ChluorofluoroHYDROcarbons) which are like unsaturated versions of CFC's (some C's or F's being replaced by H's.) My understanding of the advantage with CFHC's is not a lessened tendancy to destroy ozone (O3 --> 1.5O2) but a reduced longevity. Both CFC's and CFHC's destroy ozone catalytically (they are preserved in the process) but CFC's break down MUCH more slowly than CFHC's, so greater quantities accumulate in the atmosphere.
Hello, Anubi,
Yes, that was my second post and thanks for my first reply. Given my perpetual fascination with the universe in general and a penchant for geekiness in particular, I'm coming to appreciate slashdot more and more.

Thanks for the note on refrigeration. My assumption that a pump would be necessary was (hastily) based on my small knowledge of home refrigerators. Like you say, I neglected the likelihood that laptop cooling would aim to speed thermal equilibration with the surroundings (good for CPU's) rather than establishing greater disequilibrium (good for frozen burritos). --- Would the fundamental difference between a system like the NEC system and the 'heat pipe' be along the lines of the former's use of a pump to aid coolant equilibration (circulation/mixing)?
The idea of using gravity to get hotter coolant to cooler areas (and reverse) makes sense given lower density for warmer coolant (hence hotter gases/liquids rising, in general). However, I'm curious if, given the small size of the system and the fairly high pressures involved, entropic forces wouldn't be enough to maintain [coolant] equilibrium more reversibly (thought not truly reversibly). In other words, if homogeneity (between different phases/temperatures) does maximize disorder, wouldn't the desired 'convection' just occur on its own in a system of small size/high pressure? I'm wondering if you actually could safely run the laptop at zero-g/upside-down or if 'entropic mixing' (I hope I'm not making that up) wouldn't be fast enough to overcome gravity. The answers may well be variations on "depends what is enough cooling" but I'm curious to know what people think.
Halon is Dichlorodifluoromethane (CCl2F2) -->a chlorofluorocarbon (CFC...) It's also known as Freon-12 and Arcton and it's low BP (-30 deg C) makes it a good refrigerant. I don't know whether it would be feasible to use in a laptop since I think that the process of pressurizing the gas back to liquid phase takes a lot of energy because the pump needs to effect a significant pressure change (as it's operating at about 50 deg C higher than the boiling point at standard pressure or ~1 atmoshpere).
Also, as I understand it, CFC's are banned globally and have been replaced generally with CFHC's (ChluorofluoroHYDROcarbons) which are like unsaturated versions of CFC's (some C's or F's being replaced by H's.) My understanding of the advantage with CFHC's is not a lessened tendancy to destroy ozone (O3 --> 1.5O2) but a reduced longevity.

Also, I think that apple uses an aluminum alloy in the 12 and 17 laptops due to aesthetics as well as Al's heat-transfer properties (among other reasons)
If the developers really go all-out with the crafting, it could be a great way to attract more of the DIY crowd from places like head-fi.org
I'll could be wookie and call myself Tyll or Xin or Cmoy and work my way up to Master-class Audiophile DIY Amp-Builder. Once I figured out how to build a soldering-iron and where to get/make some breadboards and capacitors and the like, I'd refine my skills and build amps to rival the Blockhead to use with some of my HD600, specially modified to fit the shape and number of your avatar's heads and ears! I'm sure there will be a market for it eventually since it is a player-driven economy and different characters will have different interests.

I posted a little on Halon previously:

Hope that helps a bit.
