There are a bunch of man page browsers available online. They have different data sources, feature sets, and disadvantages, so here is a short comparison table:

This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).
Matrix multiplication is a mathematical operation that defines the product of

It's hard to quarrel with that ancient justification of the free press: "America's right to know." It seems almost cruel to ask, ingeniously, "America's right to know what, please? Science? Mathematics? Economics? Foreign languages?"
None of those things, of course. In fact, one might well suppose that the popular feeling is that Americans are a lot better off without any of that tripe.
There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way throughout political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."
Politicians have routinely striven to speak the language of Shakespeare and Milton as ungrammaticaly as possible in order to avoid offending their audiences by appearing to have gone to school. Thus, Adlai Stevenson, who incautiously allowed intelligence and learning and wit to peep out of his speeches, found the American people
