Interestingly, "chief" is the same word as "chef" just imported from the Normans. French had a consonant shift, while English did not, and then imported the word again with the new pronunciation and spelling.

Sorry, just saw your thing below. I see your point about [2]float64 vs. [3]float64, but that still feels like mostly an operator overloading thing (I realize it isn't exclusivly). Most of the time I've dealt with that (say, [3][3]

I can see the argument for operator overloading being necessary, but I don't understand the argument for generics. There's basically no time I've wanted generics coding Go, except a couple times with float64 vs []float64. I a

For small vectors and matrices the cgo overhead swamps the assembly speedups. For large vectors cache misses dominate, and the assembly doesn't matter as much. It does matter significantly for medium vectors and large matrices. In that

I don't use Gonum with a webserver + large calculations so I can't definitively answer. No one has reported problems, but that could be a lack of usage. One thing though is that matrix multiplication (which is a kernel for higher-

The algorithms are (basically) equivalent, and are translations from the Fortran (though row major instead of column major). As far as I know there are no major differences in the answers, though for extremely poorly conditioned matrices (1

We aren't at full feature parity, but we're pretty close. There are some big things we are missing (ODE, FFT), and we have a bunch of things they don't have (statistical distance measures being one example). We are trying to

Oh right, of course, because you're iterating the distribution. Duh. And yea, mat mul is not N^3 theoretically, but most implementations are. I've heard that some (mkl maybe) are 2.8, but haven't had someone point code to me.

by howeman 10y ago
Why do you say it will scale far beyond? Mat mul is N^3 as is eigenvalue solving. It's actually the second highest eigenvalue. The highest eigenvalue is always 1 for stochastic matrices.

How much code do you have that compilation is 3 minutes?

Removing compiling issues, keeping everything in one language. Plus, when you do, you find bugs. We've found a bunch in lapack implementing gonum (godoc.org/github.com/gonum/lapack)

In the beginning we were still trying to figure out what we wanted. There was a lot of really free-form changes, and it was easier to keep those sweeping changes isolated from one another. We're planning to do a couple breaking changes

Wow! That's a ton of stuff. I wish you were working with us at gonum. Can we work together?

Interactivity can be an important feature for scientific programming, but so is having correct underlying algorithms that are implemented in a clean, composable way. Go is a good language for such implementations. > Go doesn't have

Actually, it's mostly assembly (depending on the particular implementation). Lapack is Fortran though.

Is there any public "how to" about Gerrit? I've interacted with it a few times for Go codereviews, but not frequently enough to get comfortable. Really simple things like finding the "submit comments" button I have
