The Brief: Typing "f" into a chat is a way for people to "pay their respects" to something or someone.
Summary of Key Points. "Drooling" is the most common definition for :F on Snapchat, WhatsApp, Facebook, Twitter, Instagram, and TikTok. :F.
Historians generally agree that "fuck" hit its stride in the 15th and 16th centuries as a familiar word for sexual intercourse, and from there it evolved into the vulgarity we know today.
The F-word was recorded in a dictionary in 1598 (John Florio's A Worlde of Wordes, London: Arnold Hatfield for Edw. Blount). It is remotely derived from the Latin futuere and Old German ficken/fucken meaning 'to strike or penetrate', which had the slang meaning to copulate.
The problem is that the min3 function is compiled as a generic function that uses generic comparison (I thought this uses just IComparable, but it is actually more complicated - it would use structural comparison for F# types and it's fairly complex logic).
> let min3(a, b, c) = min a (min b c);;
val min3 : 'a * 'a * 'a -> 'a when 'a : comparison
In the C# version, the function is not generic (it just takes int). You can improve the F# version by adding type annotations (to get the same thing as in C#):
let min3(a:int, b, c) = min a (min b c)
...or by making min3 as inline (in which case, it will be specialized to int when used):
let inline min3(a, b, c) = min a (min b c);;
For a random string str of length 300, I get the following numbers:
> levenshtein str ("foo" + str);;
Real: 00:00:03.938, CPU: 00:00:03.900, GC gen0: 275, gen1: 1, gen2: 0
val it : int = 3
> levenshtein_inlined str ("foo" + str);;
Real: 00:00:00.068, CPU: 00:00:00.078, GC gen0: 0, gen1: 0, gen2: 0
val it : int = 3
