There are two attractors, it could push people to do it themselves but I think it's more likely that it evolves in stake pooling. Stake pooling in pure PoS involving trusting the pool operator to a great deal and I'm concerned it

They do have to be sharp. As an exercise, consider a metallic cone with a charge of 1 and look at the distribution of the charge that minimizes the electrostatic energy. You will find that the charge collects near the tip of the cone. In ge

I know less about J, but idiomatic K/Q is definitely concatenative. I suppose the emphasis should be on idiomatic.

The author might want to add K and Q to the list, both widely used in finance and concatenative. https://kx.com/ There's also the open source j, in the same fine http://www.jsoftware.com/ Last but not

If you think of the covariance matrix, entry i,j for i ≠ j will be floor(n / (p[i]*p[j])) / n - floor(n / p[i]) * floor(n/p[j]) / n^2 and the ith diagonal entry will be floor(n / p[i]) / n - (

If you navigate a ship while keeping the rudder straight, absent current or wind you will be following a geodesic. If you try to follow a parallel you will have to constantly be turning. Planes follow geodesics too over oceans, not para

Straight line here is taken to mean geodesic, the shortest possible path on the surface between two points. Parallels on the sphere are not geodesics!

Yes, but as you note, "in the size of the program" and the size of {the program that solves 3-SAT in polynomial time if there is one} is a constant, so it's all constant. Of course, that constant is astronomically unpractical

Technically, if P=NP then we already have a working algorithm to solve NP problems in polynomial time. It involves iterating through and running all possible programs ordered by length, giving them an increasing amount of time to run and

It's easy to forget that this is a highly competitive field. You're used to see the techniques you work with capture signal because there isn't an army of PhDs in math, physics, and computer science working around the clock t
