linear VS Exercism - Scala Exercises

Linear.Quaternion.Quaterion from the linear package has a Num instance, and quaternion multiplication is noncommutative.

That's pretty much exactly the abstraction used in the 'linear' package's Affine class, in which we find points separated by vectors.

Linear algebra: hmatrix again with its own array type (and linear but this is restricted to low dimensions)

This is very niche, but something I've wanted to do for a while is to generate some cool physics example on the surface of a sphere with https://hackage.haskell.org/package/hamilton, and display it with https://reanimate.github.io/ (using https://hackage.haskell.org/package/linear for the projection)

Do check out the linear package. It has some complicated parts, but the types work out very nicely. Your Coords type is called V3 in that package, it has a huge list of instances for all kinds of different type classes.

I've come to love the linear approach, where instead of working with Naperian (Representable) functors, you work with Distributive functors.

See also the linear library, it contains types like data V3 a = V3 a a a with all of the useful instances.

Exercism

Nice, this reminds me of Exercism, which I wish was more widely known since they seem to be good folks. (disclaimer, I donate to them)

Exercism, the free programming learning platform has initiated a challenge named: 48in24.

Last year, Exercism put together the #12in23 challenge. The goal was to learn a new programming language each month throughout the year. I was one of 135 people who completed the challenge, and I learned a lot along the way!

The list of languages contains every language on Exercism, excluding ones that I've used before, web languages, or ones that I can't download for some reason.

Learning by doing, with the help of mentors. Excellent way to learn a next language (as you are already familiar with the programming concepts).

Exercism is pretty good for beginners with some programming language, they are open source and worth contributing to.

> it might be more sustainable if courses were stored in a version controllable medium to facilitate multiple collaborators

My initial thought was to actually use GitHub to store the content. Either on Markdown or JSON - to have some version control. I like how Exercism [1] does it. But I thought it would be hard for teachers - unfamiliar with Git - to update lessons.

Then, I thought about implementing a version control system for the project but I felt I was overcomplicating things for an MVP. But I like the idea of having some kind of version control to improve collaboration.
