Most bitcoin public keys are sitting behind two levels of hashes: SHA256 and Ripemd-160. So both would need to be broken to even get the PUBLIC key. The elliptic curve cryptography would also need to be simultaneously proven flawed in order to spend the coin. The blocks in the blockchain, however, just use SHA256 to chain themselves together.. so there might be some advantage to the miners if this was flawed though it might only enable double-spend attacks which would be detectable.

The original Oculus Rift prototypes used a sensor that was readily available on the market, but ultimately we decided to develop our own sensor hardware to achieve an optimal experience. With the new Oculus VR sensor, we support sampling rates up to 1000hz, which minimizes the time between the player’s head movement and the game engine receiving the sensor data to roughly 2 milliseconds. The increased sampling rates also reduce orientation error by providing a denser dataset to integrate over, making the player’s real-world movements more in-sync with the game.

Comment 1 ms latency what? (Score 2) 104

I believe the summary put a comma in the wrong place...

9-axis motion detect with low latency (1 ms), wireless communication

Should be:

9-axis motion detect, with low latency (1 ms) wireless communication

The article mentions nothing of 1ms latency head tracking... it does mention the wireless communication latency being 1ms, however. This is a very important distinction as the latency of head tracking is what the Occulus Rift has appeared to have put the most effort into via their custom 3-way merged sensor chip.

Comment Re:Actually it usually does (Score 1) 336

Oh and I do love the saying "correlation is not causation" often said here, which is where crackpot anti-logic spills over into the /. group think. Correlation is in fact a prerequisite of causation, certainly a lack of correlation is evidence against causation?

The actual saying goes "Correlation does not denote causation", which I hope you agree, makes more sense.

Like I said, the article didn't say, but I doubt they are using object detection like facial recognition. It's easy to toss around concepts like "see humans", and impossible to get software to do it 100% of the time. I'd be willing to bet they are using infrared to detect heat, and motion to detect the size and direction of the moving objects. Maybe when the TED talk comes out we will have more info.. can't wait.

What do you think about intermediate variables that are not strictly necessary?

I'll often find myself coding some physics equations from specifications written on paper. Obviously, they are always written in math notations. What I end up doing, if not limited by cpu/ram, is to create a stack variable for each term in the equations. Basically, I'll try to make the code look as much like the paper specs as possible. The specs will ALWAYS change, and trying to figure out how the two relate some years later is a real pita. Also, I'll always preface everything with some comment like "The following is from foobar specs dated Jan 1st 2002" for the reverse reasons.

Well I didn't read anything about stereoscopic vision, so I'm guessing it is using the motion of the mosquito to track. If that is the case, then you could get hit if you stand completely still.
I'd be completely wrong if they are using infrared vision, or facial recognition, but the article didn't mention.
