@AviFS wow, thanks for all the resources, I’ll be sure to dig into them tomorrow (and I’ll let you know if i find any good books/videos of my own)
I quite liked bartosz’s book (ww recommended it too) because it’s for programmers and a little more easily accessible than videos or pirated textbooks :p
Catsters is quite interesting too, they have so many videos
Starrex that because it’s probably of interest to others too

yo wats the simplest way to prove that a lang is turing complete

@AidenChow command mapping to another TC language
E.g vyxal is TC because it can map 1 to 1 to the command set of Volatile
 
Aiden Chow

hmmm
ok so how would i got about proving knight is turing complete
like intuitively it should be turing complete
cuz it has infinite loop and conditionals
 
Steffan
Steffan
1:45 AM
knight is turing complete I'm sure
Simplest proof: In Knight, you can execute a shell command with `. Shell is turing complete, so so is Knight.

Is there a formula (without using bitwise operators) to check if a character code (guaranteed to be a lowercase letter) is a vowel (including "y")?
I tried brute-forcing, but it didn't work.

how hard did you brute force
also if bitwise is out of the question is this for a knight solution

@Steffan x**6 - 652*x**5 + 176909*x**4 - 25569200*x**3 + 2076220971*x**2 - 89804131524*x + 1616503383495 = 0
where x is the character code

lol at this point its probably easier to just do smth like (where n is the char code and a is the result) ;=aF;=s'aeiouy'Ws;=a|a?nA s=sGs 1Ls
nvm that doesnt work
but ;=aF;=s'aeiouy'Ws;=a|a?nA s=sGs 1Ls definitely works

It's just a modifier key
Mostly the equivalent of Alt IIRC?

Like alt, but when you hold down it along with other nonmodifier keys it creates special cahrs

Q: Rotatable numbers (Upside down)

F. Hauri - Give Up GitHubSearching for rotatable numbers, like: 68089 If you consider numbers upside-down, 6 look like 9, 8 look like 8, 9 look like 6 and 0 look like 0. The others digits (1, 2, 3, 4, 5 and 7 ) look like nothing... I wonder how many number could be rotatable between 0 and 1000! The answer is definitiv...

number palindrome

Q: Is there a way to optimize this?

SamI tried solving the following problem by following the suggested approach to solving the problem in the problem tutorial. However, the online judge still says my solution exceeds the time limit. Is there a way to optimize the program to perform faster? The Problem: You are given n strings s1,s2,…...

It's like going to a pizzeria because you want a burger. Maybe you can order a pizza that's similar enough to a burger that you will be happy, but you are better off looking for a place that makes burgers.

The question they are asking is not the kind of thing this site is for, and you can contort it to make it on topic, but why bother?

True. But if there is no burger joint in town the pizzeria might take pity on you

It seems pretty clearly worded as a fastest-code tips question
I would just VtC it and tell OP to add the tags, but that feels kind of pointless when I could just add the tags myself and it would make it on-topic again, right?
I mean, it doesn't really go against the OP's original intent
Should I?
Well, I guess I should leave it to OP since if it's officially a FC question then some additional detail would need to be added to keep it from being NDC
Though specifying which machine it's being run on doesn't seem like it would be as necessary in a tips question

And even if it is a valid tips fastest-code, I don't think we should really encourage those on the site because we're really not a performance optimisation community and I don't think we want to become one

Q: Numbers with Rotational Symmetry

mbomb007Given an integer, output a truthy value if it is the same upside-down (rotated 180°) or a falsy value otherwise. 0, 1, and 8 have rotational symmetry. 6 becomes 9 and vice versa. Sequence of numbers producing truthy results: OEIS A000787 0, 1, 8, 11, 69, 88, 96, 101, 111, 181, 609, 619, 689, 808,...

code-golf number sequence decision-problem
I'd say it's a dupe, thoughts?
And I'd say the linked question is a dupe too
 
GingerBot
GingerBot
7:46 PM
looks like a dupe to me
 
Steffan
Steffan
the only difference is that the new question doesn't consider 1 to be rotationally symmetric and the other one does. Dupe
I guess it's also different that the new one requires you to output the numbers in a range, the other one is just decision-problem
I guess it's slightly different as in decision-problem isn't quite the same as outputting the sequence
 
GingerBot
GingerBot
not different enough imo
 
Steffan

It's annoying how VTCing as a dupe automatically posts a comment "Does this answer your question?"

Like, spawning a python -c "xyz" command might do whatever computation you want, but since the language can't (and doesn't) specify exactly how every program outside Knight works, you can't assume it does anything useful
