A: What does Nixpkgs' `callPackage` do? For the record, this write-up is not better than any of the resources listed in the question; writing it simply helped me better understand `callPackage`. Level 0. Poor, but short `callPackage f attrset` will + call function `f` with inputs automatically supplied from `attrset` and Nixpkgs ... (more) |

What does Nixpkgs' `callPackage` do? `callPackage` is a complex function (reasons include the Nix language being lazy, usage of fixed-point evaluation, overrides, etc.), and this complexity steals the spotlight from what this function actually does and why is it so useful. There are a plethora of online resources about this topic (s... (more) |

I did not now about this - thank you! You also (inadvertently?) made a good point that perhaps HTML is not the right format - and I wonder why I didn't think of XML ... or others (OWL, MicroData, RDFa, etc.), for that matter. (Just remembered DocBook, too, and they provide default XSLT transformation... (more) |

How to establish a relationship between HTML elements (tags)? (i.e., how can one element refer to another one) Should I use the `data-` attributes for this or is there a more idiomatic way? For context, I'm trying to convert annotated legal PDF documents to HTML. Certain parts of these documents are crossed out when a new amendment is added, timestamped, and a "sticky note" directs readers to the secti... (more) |

What does "parameterised type in the positive / negative position" mean in the context of invariant functors? From PureScript's `Data.Functor.Invariant` documentation (emphasis mine): > A type of functor that can be used to adapt the type of a wrapped function where the parameterised type occurs in both the positive and negative position, for example, `F (a -> a)`. What do the terms "positive" and "neg... (more) |

Where does the name of the `pure` function in the `Applicative` type class come from? At this point in my learning journey, I simply accepted that this function is called `pure` (both in Haskell and in PureScript), but it would have helped a lot if I had known the reasoning behind this name. Both the Haskell reference and the PureScript docs use the word "lift", > Haskell Lift a... (more) |

Thank you! I totally missed `Additive` and `Multiplicative`. Some parts of my question still bother me though, but hopefully I'll be able to ask it in a more coherent manner as I gain better understanding of this topic over time. (more) |

Why is the `Data.Int` type not a `Semigroup` in PureScript but `String` is? ``` > "lo" <> "fa" "lofa" > 1 <> 2 Error found: in module $PSCI at :1:1 - 1:7 (line 1, column 1 - line 1, column 7) No type class instance was found for Data.Semigroup.Semigroup Int ``` Is this for purely technical reasons as there would have to...

A: How to merge Django model query results?

Well, it surely wasn't obvious to me right away, but once it clicked, I was surprised how I could've missed such an easy step. Thanks again and have a great day! (more) |

Thank you for the clarification! I made an edit suggestion lining up the terms - it took me unnecessarily long to understand it as I have no experience in theorem proving, so "explain it to me like I'm 5" is how I roll for now.. Is my assumption correct that you picked `h = switch f` intuitively? (more) |

Wow, the simplicity of this blew my mind. Did you come up with this on the spot or is this a well known formula in other (pure) functional programming languages?
I'm also trying to make sense how `id` can be the first argument to `>=>`, so here's another question if you are interested: [Why does `le... (more) |
