I think IoT beats wireless routers and I think there is more than one company already trying to take advantage of that opportunity.

> The many worlds interpretation is just that, and INTERPRETATION, not a predictive theory. How does the many worlds interpretation INTERPRET the Born rule? Shouldn't that be a key feature of any QM interpretation?

Loved that pun from Baudolino by Umberto Eco: "I know, Master Niketas, that the center of the universe is your city here, but the world is vaster than your empire, and there's even Ultima Thule and the land of Hibernians. True, co

Determinants have a very basic intuition behind them: it's the stretch factor of the n-volume of a linearly transformed unit n-cube (area of a linearly transformed unit square in 2D, volume of a linearly transformed unit cube in 3D, et

The source of the algorithm I described is my mind. It's so elementary that I believe it is omnipresent but disguised by more complicated math, usually due to other ways to define RS codes.

I'm a bit rusty myself (all those small mistakes I made). I'm now more concerned with the engineering side of error correction (elegant implementations and more importantly a totally new class of dynamic error correction I have in

If RS(n,k) code is defined as Sum[i=0..n-1] Xi Zi^j = 0, j=0..m-1, m=n-k , where {Xi} are codewords and {Zi} are locators, then for any polynomial P(Z) of degree less than m we have Sum Xi P(Zi) = 0 . Now, let's erase m val

Using a general matrix inversion algorithm to decode Reed-Solomon erasures is an atrocity. The only difference between encoding and decoding erasures is that we restore m=n-k code word values at static locations, k+1..n , when encoding,

The tale of the frog and the bird may be good for a less mature audience but here we can really go with a richer analogy: the two views correspond to how a virtual machine is seen from within and from the environment in which it runs. I pre

No, as it clearly qualifies for the second part of my statement: > Being lock-free implies using Compare-And-Swap - a very powerful synchronization primitive. Just look inside https://github.com/liblfds/liblfds7.1.1&

I'm not aware of any unsynchronized concurrent queue implementation. Being lock-free implies using Compare-And-Swap - a very powerful synchronization primitive. I agree that the current implementation won't survive integer overflo
