Project mention: The sad state of property-based testing libraries | news.ycombinator.com | 2024-07-04
> - rose tree "integrated shrinking" (eg. Hedgehog) follows the constraints of the generators, but has issues with monadic bind.
We're at the limits of my amateur knowledge, but I believe this is a fundamental limitation of monadic bind/generators. Instead, you should prefer applicative generators for ideal shrinking. https://github.com/hedgehogqa/haskell-hedgehog/issues/473#is...
In other words, applicative generators do not use "results of generators to dispatch to another generator", but instead shrinking is optimal due to the "parallel" nature of applicatives (I'm using "parallel" in the monadic sense, and not the sense of article's "threading" sense).

Project mention: SDK-Driven Development: A Litmus Test for Good Software Design | dev.to | 2025-05-15
I learned how to convert such principles to my own inner voice (or one of them). It makes it easier to internalize them for practicing. For example, I noticed how my inner voice was motivating me to use the HtDP Design Recipe in my career even today, after teaching it more than 15 years ago. I have been actively using doctest in Python and doctest in Haskell, which are analogous to "Examples" and "Tests" in the HtDP Design Recipe. I even changed my go-to language to Haskell to paint HtDP Design Recipe's "Contract" more clearly, using strongly typed data definitions and type constraints.
