For some reason, I have a perfect recollection of my early programming mistakes. My first was not understanding why a perfectly reasonable test like this didn't work:pic.twitter.com/rSuqFdmGMD

In a functional logic language, "a or b" isn't an operation on booleans. Rather, it creates a backtrack point where the current test you're performing is run twice: first with "a" and then, if necessary, with "b".
In these languages, failure isn't represented by a boolean called "false". Rather, it's a control-flow construct. In an "if" statement, failure runs the next backtrack and, if there are none left, jumps to the "else". Hence you can simply write:pic.twitter.com/O6qFJVXMhX
Some of us use Prolog in actual industry.
Ditto. I have been using Logtalk and Prolog in industry for the past decade. I’m using it now. I’m also aware of others doing the same. On the grand scale of things, we’re a minority but we do exist.
Learning and using Haskell in college was so much fun and it made so much sense (it was the second programming language I learnt, after C). A lot of the OOP languages now use some of the best features of functional, but I have always wondered why industries don’t use FP/FLP more
25 years ago the creators of Racket asked themselves the same question: "If functional programming is that good, why is nobody using it?" I don't have the answer but there are clues in the mainstream acceptance of the functional features in Rust. https://blog.racket-lang.org/2020/05/racket-is-25.html …
PLZ GIVE ME EARLY LOOK AT SEASON 3 PLZ TIM!!!
can you bring back stranger things item shop plz
Bro you forgot about the existential C-0778 Nolic Modulators that Cryptify the nodes virtual hydrollic function to higher dissonance of Mainframe tech valves.
Python's any() and all() nicely handle these commutative OR/AND scenarios- failing fast on a single True or False, respectively. For this simple test you would just use `if a in (0,1)` though.
