Comment Re:It's a mobile sensor and communications platfor (Score 1) 257

- A good (near-medical quality) heartrate monitor is doable right now, but would benefit from better color detection in the camera and for Android, a better API. It only works on iPads right now.

I got an app called "instant heart rate" on my Lumia 920. It's free but does appear to work pretty well, and it's easy to use.

According to the website (www.azumio.com) it's also on iOS devices. Don't know if it's near medical quality though.

The plot line is better than Bioshock and the world is friggen awesome.

Solid 10 so far.

If Bioshock 1 is a 10 I give Infinite a 8. Both the plot and the gameplay is a step back. The game is better than I expected though.

Anyone else creeped out by the facial animations? They're freakish. Bioshock 1 too had poor character animation, but there they hid it with dim lighting. Besides the poor animation I've also seen characters walk through tables or throws stuff through walls. There's apparently no hit detection when an animation plays. Elizabeth also clearly have the ability to teleport when you're not watching, just turn around and she's there. A bit like Dr. Watson.

Comment I pledged $60 to project Giana (Score 3, Informative) 86

And for that I get the game, soundtrack and art book in a jewel case. Shipping is free, and had I pledged more I could have gotten more stuff. Had the kickstarter failed to be founded, I would have paid nothing.

This particular project has a good chance of delivering, having already made a working demo of the game, so the $60 was not much different that preordering some limited edition of the next CoD game. Without kickstarter this game would never have been made, so in my eyes kickstarter have served a purpose that no other service I know of could have managed.

Naturally there's always a chance they will take their money and run, but the last $60 CoD game I bought was absolute garbage (despite stellar reviews), so there's always a bit of risk involved no matter how you spend your hard earned coin. It may not be a risk you are willing to take, but fortunately plenty of folks are, and thus project like Giana can see the light of day.

LINPACK is highly parallel. I.e. why I stated "LINPACK like workloads".

How useful LINPACK is to super computers isn't within my field of expertise, but if Arm is truly better on a performance per watt scale and some other constraint don't step in, then it does not matter how much faster a single chip is than the arm solution, as one can just add more arms (for LINPACK like workloads).

I'm somewhat skeptical to that article, reads too much like an advertisement, but the results may still be significant for the super computer landscape.

So, it is saying that a car with an engine that can get 400mpg is more economical than one with 30mpg, but they leave out the important part that it will take you 10x longer to get to your destination. I hate the trite "typical marketing", but that is what this is

Unlike with engines if it's truly better on the "performance per watt" scale you can build super computers with 10x, 100x, whatever it takes of extra chips, to get there faster on the same power budget; Which would make Arm A9 viable for people with LINPACK like workloads, unless the cost of extra networking gear (and other support hardware), kills them.

Wasn't some company working on an Arm based super computer? They must be thrilled.

GDI has been hw accelerated since Windows 3.1. There was a time they even benchmarked graphics card on how quickly they accelerated windows drawing calls.

GDI+ introduced different text rendering and alpha colors, but you don't get anymore hardware acceleration in GDI from GDI+.

From Wikipedia's GDI article on Vista: "GDI is no longer hardware-accelerated by the video card driver"

Comment Re:crash faster (Score 1) 563

I was thinking on the GDI part of Windows, it is software rendered on Vista. Some applications ran quite badly because of this.

If you wrote WPF or DirectX apps on Vista you got hardware acceleration, but 6 years later and most stuff is stilling using GDI instead.

Looking at the article they're talking about improving Direct2D and SVG performance, which is something apps are starting to use I believe.

Comment Re:crash faster (Score 1) 563

Many Windows crashes was caused by hardware acceleration. As a result Vista supported less hardware acceleration than XP.

This makes me wonder if what they've done is gain back some of that performance. They say they render lines and Rectangles faster, and that's hardware accelerated on XP, while software on Vista (don't know about 7).

Would you areee that in a million years it is possible, via the mechanism of evolution, that a housecat will teach mathematics at a college level.

Areee? No. A housecat will never teach mathematics at a college level, just like how h. ergaster never got to do that (though some distant descendent eventually did).

A million years is also fairly short. It took more than that for man to evolve, and the rate of genetic mutation, horizontal gene transfer, etc, is fairly constant. Cats are further away from modern humans than man was back then, so 1 million years of natural evolution may simply not be enough to get a college ready smart!cat. And even if this happens, there could still be house cats around... perhaps the smart!cat will have one as a pet.
