@Dennis Fun fact: the first word of this fact actually was a lie.

Erik the Outgolfer

There is a difference between the definition of fun and funny I think. (I searched for define fun and define funny, the latter implies laughter.) Also, I agree with ^ too.

DJMcMayhem

Fact: this sentence is false

DJMcMayhem

@flawr Because of portal

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@flawr IMO the most realistic options would either the robot saying "screw you" or just ignoring the statement

Erik the Outgolfer

I think that a robot isn't smart enough to detect contradictory statements most of the time, because detecting them correctly means that the halting problem has been solved, and know the meaning of the words of a sentence.

Loud keys tend to mess with you when you have to focus. Of course, having them is OK.

Recency illusion

The recency illusion is the belief or impression that a word or language usage is of recent origin when it is long-established. The term was invented by Arnold Zwicky, a linguist at Stanford University who was primarily interested in examples involving words, meanings, phrases, and grammatical constructions. However, use of the term is not restricted to linguistic phenomena: Zwicky has defined it simply as, "the belief that things you have noticed only recently are in fact recent". Linguistic items prone to the Recency Illusion include: "Singular they": the use of they, them, or their to reference...

@EᴀsᴛᴇʀʟʏIʀᴋ there's other problems. Range, print and / come to mind

Eᴀsᴛᴇʀʟʏ Iʀᴋ

eh, I dno't mind / and print but yeah range could be fixed

Erik the Outgolfer

Python 3 is an anti-golfing language: print() instead of print, range is py2's xrange, integer division is int(a/b) and not a//b, etc.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

it's not that bad for golfing

range is the same really, it's pretty much a list

DJMcMayhem

Oh yeah, and input. That's the other dumb thing with Python 2

Eᴀsᴛᴇʀʟʏ Iʀᴋ

even though it's techinically an iterable

@DJMcMayhem eh, not really IMO. I think it could be renamed, but I like having both

Kritixi Lithos

@EriktheOutgolfer Just look at Java and then tell me which language is an anti-golfing language

Python2 is often a couple bytes shorter than Python3

hey I wanna test if I can get the censius badge on a differnet site

but sometimes Python3 blows it out of the water with new features

Erik the Outgolfer

I think the most anti-golfing language is INTERCALL. It's designed to be one.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

7:33 PM

@orlp yeah

DJMcMayhem

@EᴀsᴛᴇʀʟʏIʀᴋ But why? You could just do eval (input ()) which is so much saner!

orlp

like extended unpacking

f(5,*l,3)

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem I assume mobile spaces, but eh I like it being easy

IMO eval_input could be a thing tho

orlp

or the new format f"test{a:.5f}" strings

DJMcMayhem

@EᴀsᴛᴇʀʟʏIʀᴋ but it's dumb and dangerous

Kritixi Lithos

@EriktheOutgolfer I'd choose 8. It'd be in the middle of the day (since it is an 8-hour day)

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem I think it should be renamed to eval_input() and then raw_input() be plain input()

Erik the Outgolfer
