If you squint hard enough, you can see all of them as linear transformations (even the 2D images :-). I politely disagree about covariance and Hessians. I can squint and say that the Hessian provides a change in gradient when multiplied by

I think this is spot on. Depending on what you're doing, a matrix can be: - A linear transformation - A basis set of column vectors - A set of equations (rows) to be solved - (your example: parity equations for co

The names in stdint.h are ok, but the way they play with library functions like printf() and scanf() is not so great. Given an int64_t value x, each of these works on some platforms and is wrong on another: printf("here's y

Yes. Even if they don't use your data (incredibly unlikely), they win just by scamming privacy conscious, or even apathetic, people into paying more.

I see a lot of dismissive comments in this thread, but I think Seq looks really nice. I'm not interested in bioinformatics, but the rest of the features look like what I would've wished had gone into Python 3. I hope it is a suc

Nah, you're making a good case. I think what you're trying to say is to test the CPUID bits for a consistent subset of AVX512 flags and treat it all as one or two clumps. There was always going to be a fallback path for older su

That's a great picture (thank you), but it really looks complicated to me. :-)

Additionally, it looks like each subset of AVX-512 past the foundation is an optional feature and needs to be tested for. With only a few exceptions (usually as a result of bickering between Intel and AMD), previous ISA extensions implied

Appealing to "common decency" is just the same as "being owed". I think you're mincing words to avoid sounding entitled, and I don't think anyone is even entitled to two lines in a README, much less at the top
