I believe they mean "embarassingly parallel" to mean easy to implement a simple parallel implementation on an Intel CPU. SSAA and MSAA are both problems that require texture sampling hardware to implement quickly and there is a lot of information for MSAA that requires knowledge of the geometry (edges). Since MLAA can be done on the finished bitmap without requiring geometry information or texture sampling hardware, it is easy to parallelize on a CPU while the other techniques work much better on GPU's than CPU's.
I guess no one in business uses OpenSource or Macs ?

Hmmm... surprisingly well argued points... it's an unusual day for Slashdot. I guess the main reason to use pi instead of tau then is for "backwards compatibility" and "legacy math".

No, it's for people who are too lazy to multiply by 2. Consider that physicists have two constants for the same physical constant -- h and hbar -- because tracking the 2*pi factors is a pain. (For that matter, tracking the 2's with pi is also a pain. It's not really intuitive to look at 4*pi^3 and realize that in this case, that's because it's (1/2)*(8*pi^3).)
Then why not just write it as (2pi) ? For example, ( (2pi) ^3) / 2 rather than (1/2)*(8*pi^3) is as simple as Tau. Anytime you integrate or differentiate or go through powers or actually do *ANY* math with pi times any constant, you're going to be getting new constants anyhow. I doubt constant tracking is really all that hard and if you're too lazy to multiply by 2, you're probably going to be too lazy to explain that what your overloaded symbol is.
And tau is no better. What are we gonna do, teach that the area of a circle is tau/2*r^2 ?? You're just pushing laziness of constant from one group of equations to another. It's a lot of nonsense work with zero sum gain -- any perceived increase in efficiency by not having to multiply by two is gonna get cancelled out by having to divide by two or keep track of two symbolic irrational constants.

Yes, but e^(i*Pi)+1=0
Overrules pretty much everything.
The whole idea of Tau is for people who are too stupid to multiply by 2.
Throwing in e (the irrational number whose powers are the inverse of natural logarithms) and i (the imaginary square root of negative one) is gonna confuse them even more than taking Sara Palin to a book reading club.
Yes, it's the same problem as the film industry: Increased budgets means more money is at risk, meaning you're only allowed to play it safe.
When you're playing with your own money, you can do whatever you want, either in independent films or independent games, and only need to sell to customers, who desire innovation and fun. If you need to finance your project externally, you need to sell your not-yet-started project to your prospective backers, who desire monetary returns with reduced risks.
Exactly... plus there is plenty of innovation in the low-development-cost $0.99 games for phones which target a generally non-gaming audience. Games like "Cut the Rope" are quite innovative and seem to have a much broader appeal than just for hard-core gamers. Heck a couple guys in a garage can make a phone game. It requires a studio with at least 100 people and a $20M+ budget (plus another $10-20M for marketing) to make a AAA+ title.
There doesn't appear to be a single occurrence of "you're not gonna take away our guns" in that conversation with the British.
Furthermore, his ride was still primarily to alert Americans (despite Palin's claims to the contrary). It appears that his conversation with the British occurred only because he was stopped and questioned - it was most likely not part of his plan to be deliberate detained and questioned by the British.
Finally, even if some of the historical records may support a small portion of Palin's absurb claims, I am highly doubtful that she, like you, has read the Massachusetts Historical Society's Collections, First Series, Vol. V.
And before you spent that absurd price on a 10,000 RPM drive I suggest that you look at it's transfer rate as compared to a basic Seagate 7200 RPM drive. My understanding is that the Seagate actually beats out expensive drives like the Raptor. The reason? Because the 10,000 RPM WD drive still uses traditional recording while the Seagate uses perpendicular recording, packing the bits much closer together and thus allowng more to be read in the same time, even at the lower rotational speed.
There are multiple parameters in drive speed. Sequential operations may be faster on a drive that uses perpendicular recording but random operations will be much faster on a higher RPM drive. In fact, sequential performance on HD's may be faster than many previous generation SSDs. Then again, if you are doing lots of random operations, a good SSD will kill ANY mechanical hard drive for speed.
You also lose storage space with the newer NAND - the 60GB drive formats to 55GB and the 120GB drive formats to 118GB. So it's a combination of being slower and being more expensive per GB. The storage space is lost because smaller flash is less reliable and they need to set aside more storage for error handling when blocks fail. One of the main reason the drives are slower is that they use half as many storage chips so there are less lanes in use. If you get a larger capacity drive that still populates the whole board, they don't slow down as much but the slowdown is noticeable on the 60GB model.

Google and Facebook make money several way - you may try to avoid some of them, but if you use the services you can't avoid all of them.
1) Selling ads to you. If you explicitly block ads, you may be violating their terms of services. Still, most users do not block all ads or it's a pain to block 100% of them. Perhaps you miraculously block all ads.
2) Selling User Data to advertisers. Anything you upload or post may be used for advertising. Facebook will use your pictures to advertise to friends unless you navigate some hard-to-find settings and explicitly opt out. Perhaps you do not post to FB and have enabled all you privace settings correctly.
3) Encouraging viral links with pay per view hits. Example: Everytime you watch a youtube video that has a small video ad in front of it, you are an "impression" for that ad and they are getting paid. Perhaps you never watch YouTube though.
4) Every action you do on these sites from pages you view, links you click, and search terms you enter is saved with IP address. If you are using these services at all, even anonymously, they are still collecting and aggregrating data about your usage and that data can be sold. They may be counting view impressions on associate sites (that are not even the main google or facebook sites). Just being here and posting snide comments like your previous one is adding to the data being collected.
Because of #4 if you even visit these sites (or any associated sites), they are somehow incorporating your input into their business model. The only way for you to claim 100% freedom from being a product is not to play - and not playing today involves not connecting to the internet at all.
Won't BOCHS and QEMU work* regardless of host architecture.
*By "work" I mean run the apps... I know they're both fairly slow compared to native apps. However, they could be made faster by only emulating the app and allowing the WinApi calls to be thunked to native calls.
Well, that's why you don't put all of your apples in one basket (pun intended).
There are currently over 100 Million activated Android devices -- currently more than iOS. While it's true that Android is playing catch up to iOS on Tablets and no Android tablet is competing commercially with iPads, this will change. Google IO (going on right now) is highlighting a large number of places where Android is innovating and the newest hardward that will be released in a couple months will start competing with Apple on the "sexy" front as well (thinner, sleeker, better, less "clunky" designs).
If you've already got the technology backend and business deals in place, you might consider writing an app for Android.
It might be more "complicated" but it's probably more useful since currently a lot more systems have GPU's than AES-NI, given that AES-NI is only on a subset of Intel's most recents CPU's.
You mean, in other words, you're alive, or you're dead?
It does seem a bit daft to not have an MMU. Getting MMUs in desktop machines was a major step forwards in personal computing. I don't particularly want to do without one any time I am running multiple processes...
No, it's not all possible states. There are many things you can rule out from the limited information in the article. While there are dozens of ways to connect hardware to each other and have them access memory or communicate, the way this chip seems to work is as a limited accelerator (i.e. like video cards or physics cards) rather than a true CPU for the OS. There's only so many ways a chip like this can coexist with a modern CPU and a modern OS and without an MMU. You can't have it access the same memory as the CPU directly because without an MMU, you have no memory protection so it'd be a huge security hole. Probably, either on a bus or card and again with a small pool of local memory and possibly on chip memory. They made CELL-based SPU accelerator cards for PC's and this is very likely in the same category.
Sublimation is not a state. It is a specific process involving the transition between two states of a single compound.
and in this case, a good descriptor for the oxidation process
No it's not... please look up the definitions of sublimation and oxidation. One is an endothermic phase transition of a single compound and the other is a chemical reaction which transforms one compound into a molecularly different compound.
Sublimation is a scientific term for when matter undergoes an endothermic phase transition at temperatures and pressures below the triple point directly from a solid to gaseous form, or vapor, without passing through the more common liquid phase between the two. It is a specific case of vaporization.
The most well known example of a material that undergoes sublimation is dry ice, or frozen carbon dioxide.
OXIDATION IS NOT SUBLIMATION. Pray, enlighten me: What part of Oxidation is related to phase transition diagrams and triple points?
