People don't tend to react well to feedback from a random internet person, no matter how respectful or well-intended it is. Especially the ones that also don't react well to a minus-one fake internet point from an unidentified use

It's the first time I see usernames referred to as "ldaps". Learning stuff like this is why Hacker News is my favorite HTTP :o)

Unfortunately there's this idea that functional programming is just about using lambdas for everything. For me, proper functional style is just about decoupling business logic from state and side effects, and this can still be done wit

I've been using mostly paper for my notes for more than 15 years. Of course I have a system that works for me, and it has evolved effortlessly over that time through practice. If I had to explain it to you it may sound convoluted, but

Is this what you wish? ['10', '10', '10'].map(parseInt) === [10, NaN, 2]

There are many, all with awfully googleable names: j, k, q, etc.

I think none of http, www or .com actually work anymore for all audiencies. What I see more often is stuff like "<instagram logo> @burrito_catering" or "<facebook logo> burrito_catering".

In Spanish it means "badly", which is an encouraging goal to give the project a try :)

I'd add Pandoc to all the ones mentioned in sibling comments.

Python has pyparsing: https://pypi.org/project/pyparsing/ Maybe it's because non-FP languages typically don't support operator overloading, so you'd end up with verbose grammars like: new Lite

FP practitioners are guilty of this as well, when talking about "the Maybe monad" or "the IO monad".

Originally there was no way of abstracting over an arbitrary number of type parameters in the language, so a different trait was required for each arity. The choice of 22 was arbitrary, I think. This is no longer true in Scala 3, so there

I predict all languages will adopt some form of sum types and pattern matching in the next 10 years. They will go from esoteric to mainstream in the same way lambdas did.

A recurring joke in functional programming books is some footnote mentioning that currying was discovered by Schönfinkel but named after Curry because "schönfinkeling" didn't catch on.

Since a PDF can begin with non-PDF content, then pi itself is a valid PDF file.

There's a utility called dtrx ("do the right extraction") that does basically this, and also makes sure that files are always extracted into a directory.

You can create it yourself: Prelude> s ->> f = f s Prelude> [1..100] ->> take 10 ->> filter (not . odd) ->> drop 3 [8,10]

As far as I know, they were originally introduced by Niklaus Wirth to describe Pascal's syntax. See the last pages in this manual from 1973: https://www.research-collection.ethz.ch/bitstream/handle/20....

WellActually™, Some is a synonym of Just, Maybe is a synonym of Option, and Nothing is a synonym of None.

I'm also a FP fanboy, and this concept doesn't quite convince me. I'm not sure a Maybe type really helps that much in a dynamically typed language. All the safety you get from using Maybes is worth Nothing (pun intended) when

There is not much to learn, a monoid is a very simple abstraction. Think for example about learning about the "iterator" abstraction. It's just something with "hasNext" and "next" operations, nothing more

There's also a rig (a ring without "n"egatives): https://ncatlab.org/nlab/show/rig I agree. Too cute for its own sake.
