mtl-style-example VS Exercism - Scala Exercises

Re: effects libraries, it's probably worth starting with e.g. https://www.fpcomplete.com/blog/2017/06/readert-design-pattern/ https://www.parsonsmatt.org/2018/03/22/three_layer_haskell_cake.html https://github.com/lexi-lambda/mtl-style-example if you're just getting familiar with the ecosystem. I'll add, anything written by the the people I linked to in this comment is probably worth reading as well.

Personally, it felt to me like, once I really understood monad transformers (https://hackage.haskell.org/package/transformers) and mtl (https://hackage.haskell.org/package/mtl), the reasons they both exist and how they are distinct, how you use them generally and what common patterns are around structuring your app (see e.g. https://github.com/lexi-lambda/mtl-style-example and the 3-layer-cake link someone else provided here for two), a lot of stuff in the ecosystem suddenly became comprehensible and useful to me, in a practical, "real world" way. In fact I'd go so far as to assert that getting comfortable with mtl in particular is the biggest single step you can take to being able to build arbitrarily useful real-world apps that are no longer toys.

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.
