CMC: given a character, return its position in a standard US keyboard. The position is defined by which row they key is in (the first being the escape row) and which number key (from left to right). Only printable ascii will be input, and characters with multiple solutions may return any result. 0 or 1 indexed

Okay so, I've got a challenge in the sandbox (not at all fleshed out, just a title) that I want to discuss/get feedback on, to see if the concept's worth pursuing

Any feedback?

@Nobody Vyxal's a solid choice, it's got a big community and is designed to be easy to pick up

Pip is an older golfing language but uses a more familiar model. Jelly might be more familiar if you know APL/J/K, but otherwise it's not easy.

Japt is still pretty competitive IIRC, and if you know JS it might be a good choice

Quickly approximate the square root of a float As in like, constant-time and almost instant, but off by a lot. No time for looping here. This is going to take a lot of work, since I'm going to make an emulated CPU which will allow more precise timing.

Everything is O(1) if you query an API /s

Unrelated String

are you thinking of scoring on some weighted combination of speed and accuracy

Radvylf Programs

03:24

Yeah

Something like, your speed gets multiplied by the difference (division-wise) between your answer and the correct one

So if you answer 0b1.10 * 2 ** -2 and the correct answer is 0b1.1101... * 2 ** -2, you'd get a multiplier of about 1.009

Unrelated String

and have some like constant factors in there to make sure it's not viable to do something too wildly inaccurate like just halving the exponent and leaving the mantissa alone

Radvylf Programs

That's exactly what I was planning on using as a baseline actually. I'm going to aim for that to about double your score.

as in the "conditional evaluation" syntax you're asking about is called the ternary operator

because it takes three arguments

@lyxal you should include it in vyxapedia.hyper-neutrino.xyz/beginners#flags

we'll update it a little later

if not hyper, I will when I get the chance

06:08

ok, Jelly has the same problem btw ;-)

but then, it's a little obvious given the hello world program

back from test ;-) tho it is irrelevant

these golfing languages don't have a ternary operator because there's probably shorter ways of doing conditionals

ok

`string a` →a # a = "string a"
`string b` →b # b = "string b"
←a →temp      # temp = a

←temp →b      # b = temp (swapping the values of a and b)

hello!

sanity check: if I toss 10 coins and count the number of heads and tails, is the prob of getting each possible outcome 1/11?

pxeger

by "each possible outcome", do you mean "each possible total number of heads"?

graffe

yes

(heads and tails but the number of heads determines the number of tails)

I think I have a simpler solution to my challenge if I am not going crazy

pxeger

if so, no, it's a binomial distribution

graffe

@pxeger how can one outcome be more likely than another?

pxeger

with n=10 and p=0.5

@graffe on average, you'll get 5 heads for every 10 you flip

the chance of getting no heads is (1/2)^10, which is pretty low

graffe

08:26

that is true but the prob of getting 10 heads is the same as getting 5 isn't it?

isn't the prob of getting 5 also (1/2)^10, ?

pxeger

no, because you can get 5 heads in many ways: HHHHHTTTTT or HHHHTHTTTT or HHHTTHHTTT or ...

graffe

what is the prob of getting 5 heads?

@pxeger argh... you are right!

then I don't have a simpler solution to my challenge :)

@graffe you pinged anyways ...

yesterday, by PyGamer0

> This is why we now need to store the length together with the pointer, duplicating the amount of information stored by the system.

does this mean that if C/C++ was properly designed, the pointer will have the length information so we don't need a separate variable?

(quote from "Notes on programming")

pxeger

you don't always need to do that though

for structs, integers, etc., the size in memory is fixed and known at compile time

emanresu A

^

pxeger

it's only arrays and things that need length

PyGamer0

well the book is referring to malloc and free

yes arrays

graffe

09:43

@PyGamer0 I don't think you can unping can you?

pxeger

and length is not an inherent part of a memory address, so it doesn't really make sense for the pointer to somehow "contain" the length

PyGamer0

@pxeger but doesnt the computer know how much memory is allocated?

pxeger

not all pointers point to the start of an allocated block

PyGamer0

how does a computer know how much bytes to free?

@pxeger hm true

@pxeger but then does free work?

on that pointer

pxeger

you can't call free with a pointer that isn't exactly the same pointer that malloc once returned

well, you can, but it's undefined behaviour

> The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc(), or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs

from man 3 free
