Church Numeral oriented Haskell Programmer:

    three = \f x -> f (f (f x))
    fac = \n f -> n (\f n -> n (f (\f x -> n f (f x)))) (\x -> f) (\x -> x)
    main = print $ fac three (+ 1) 0

Evolution of Picolisp coder. [https://git.envs.net/mpech/tankf33der/raw/branch/master/vers...]

How often do you code in pico lisp? I think it's a neat project, but haven't really found a use yet.

"fac n = product [1..n]" is still something I use at times. It's a beautiful line of code.

Plus it fuses the list creation and consumption, there is no list in the compiled program.

The invalid certificate and the oddball text encoding is illustrative of the Haskell programmer's inability to cope with practical computing problems.

lukan• 2 years ago

It is from 2001. And maybe not maintained anymore. Probably also a possible explanation.

Tabular-Iceberg2• 2 years ago

The meme that Haskellers never accomplish anything practical is probably even older, maybe as old as the language itself.

The invalid certificate [...] is illustrative of the Haskell programmer's inability

Why would one assume the invalid certificate is caused by that particular professor instead of the IT department's staff at the University of Calgary?

It's a joke.

My experience is that this may be illustrative of academic programmers. People working in industry are expected to produce something, regardless of the language. This is why I'd recommend academics to spend a bit of time in the industry, regardless of it feeling awkward/inconvenient, of not being given time to go deep in any specific subject.

People working in industry are expected to produce something,

Yeah, academics are only interested in producing silly papers to justify expensive trips to exotic conference locations.

Meanwhile, industry produces important and useful stuff like Scrum™ Poker-planning estimates and Jira®-powered burndown charts to track completion of their Confluence© fully-documented user-stories.

The article predates the popularity of UTF-8 encoding on the World Wide Web.

I'm glad I don't work with any post-doc Haskell programmers

vrnvu• 2 years ago

They don't _work_ either :P

fuzztester• 2 years ago

They do work.

They post docs.

I have a similar list of FizzBuzzes in Lean from when I started programming in that language:

I wrote more, but it got too silly.

quickthrower2• 2 years ago

There is a Y Combinator in there!

GuB-42• 2 years ago

As a C programmer, I think it is missing something like

  -- works for all 32-bit integers
  fac n = [1,1,2,6,24,120,720,5040,40320,362880,3628800,39916800,479001600]!!n

tromp2• 2 years ago

It does have the non-truncated equivalent "Memoizing Haskell programmer"'s

fac n = (scanl (*) 1 [1..]) !! n

jayceedenton2• 2 years ago

My first thought was, "Needs more monads".

Sure enough, in the commentary:

Monads are woefully un-represented here; I would be grateful if someone could contribute a few (progressive) examples in the spirit of the development above.

jayceedenton2• 2 years ago

fac n = product [1..n]

This is a beautiful line of code.

In all seriousness, I'd probably prefer to find the Junior or "Another junior" version if I was browsing a project.
