@RedwolfPrograms What does it do?

hyper-neutrino

with my limited knowledge of bash, it looks like it runs all of your previously run commands (at least, the ones in history) when you start up bash?

Me when I have to present a major work shortly in front of roughly 20 people + markers

And me when said major work is made using thunkable

user

I'd be more worried about why there are roughly 20 people and not exactly 20 people. How do you present to 20.5 or 19.8 people? Must be quite distracting

@hyper-neutrino Good to know, I'll put that away in my list of pranks to pull on people

Redwolf Programs

No, it does it on loop

for the new challenge, correct me if i'm wrong, but isn't a left-to-right sweep sufficient to determine if it's solvable?

like just enum, filter out zeroes, check pairs for equality and distance

Yes, a sweep should work

My best performance in mania btw

damn. i can't even read the incoming notes quickly enough :P i am really bad at mania cuz i mostly just play regular osu (which i'm also not good at)

do you play normal osu too or just mania

Bubbler

2:37 AM

I did play all 4 modes

hyper-neutrino

ah, nice. i've tried out all of them but i mostly just play the main mode and sometimes mania for fun. have you ever played quaver before?

Bubbler

std or mania? I don't think I tried it in mania (I haven't really played osu since I got a job btw)

hyper-neutrino

sorry. i meant the game quaver, not the map, lol :P it's similar to mania; IMO a bit cleaner and better

ah. yeah i haven't had as much time to play in uni especially during my work term now :P also cuz i play too many different games and i'm not actually any good at any of them

Bubbler

Ooh. Didn't know of quaver the game

hyper-neutrino

ah. i saw it in a review of a bunch of different rhythm games :P (can't find the vid anymore) the only problem is there aren't as many maps as osu cuz it's not as popular (also i can't figure out how to get skins to work lmao)

Okay, seems like a fourth option: The BIOS doesn't know the SSD exists at all, but for some reason it still tries to boot about half of the time and goes to a black screen instead of an error message

hyper-neutrino

have you tried booting from a USB? idk if that would help but maybe you could sort some thing out? prob not

idk how to computer

Redwolf Programs

I just tried

lsblk and lspci don't show the SSD exists :/

user

Nvm I misread that

Redwolf Programs

I think my dad has some security screwdrivers somewhere, so I can try to disassemble it and remove the SSD to either fix it or grind it into fine powder and order a replacement

Unfortunately it'll most likely be option two

And there's nothing worth so much to warrant sending it to a recovery company, just a bunch of random projects and some minecraft worlds

Q: Calculate \$ \lfloor n \log_2(n) \rfloor \$, exactly

Given an integer \$ 2 \le n \$, you need to calculate \$ \lfloor n \log_2(n) \rfloor \$, assuming all integers in your language are unbounded. However, you may not ignore floating-point errors - for example, in python lambda n:int(n*math.log2(n)) is an invalid solution, because for example for n=...

code-golf math number integer

StackMeter

@RedwolfPrograms give me an example of such an answer

Redwolf Programs

It's by iota rather than Arnauld/xnor, but this is a good example

Adám

2:20 PM

@Anush For comparison: In APL, it is ∪∊

rak1507

pretty much a direct translation

Wzl

except ∊ is more general

rak1507

⊃∪/ also works

Wzl

and python has horrible anonymous function notation so either you change the python to lambda list: set(''.join(list)) or you change the APL to ∪∊list

StackMeter

@RedwolfPrograms verbose

Anush

2:24 PM

@Adám thx :)

Wzl

@StackMeter compared to what? Jelly?

rak1507

@Wzl yea apl trains are great

Wzl

except the odd-even kludge

Adám

Except that lots of things naturally come form that pattern.

@Wzl It is actually overpowered, as it'd fail if you wanted to find the set of, say, multiple lists of strings.

@rak1507 Yes, and that's a bit more general, but not as general as ∪⍤⊃⍪⌿

Wzl

@Adám don't get me wrong, I like forks but I don't like APL's overloading that makes the odd-even rule necessary

Adám

2:29 PM

I see. Right, Jelly also has the rule in principle, but you don't think about it, because each atom has only one valence.

StackMeter

@Wzl even Python

Wzl

@StackMeter I completely disagree with you there

Redwolf Programs

JS is wayyyy golfier than Python

Adám

@Wzl I wonder if there'd be merit in an explicit Monadically operator, kind of what K has as :

Wzl

@Adám I'm making an array language with an explicit dyadic operator instead (that also happens to be : :)

Adám

2:32 PM

So 2+:3 ?

Wzl

yes, exactly

Adám

Hm, yet again, this would look better in a Left-to-Right language, I think.

Wzl

it is left to right :)

Adám

Adám

2:34 PM

Wzl

Adám

Yes. Thanks.

StackMeter

@Wzl prove it

JS is even more verbose than Python

and that's amazing

Redwolf Programs

???

StackMeter

because Python has huge syntax for some things

Redwolf Programs

2:39 PM

How is JS more verbose

StackMeter

for (i = 0; i < [insert number here]; i++) for one

Redwolf Programs

That's the verbose syntax...there's for of and for in and map and recursion

Wzl

@StackMeter JS has a higher golfing rating

rak1507

@StackMeter that's less verbose

Redwolf Programs

JS's for loops can actually be quite golfy

They were the meta for years

StackMeter

2:45 PM

explain

Redwolf Programs

You can put anything in the for(w;x;y)z

It's just a while loop, but way golfier

Wzl

@Wzl After using it a bit more, ruby has improved in the ranking and is now ahead of javascript

StackMeter

so as i said

the s/</> regex works

Redwolf Programs

Actually that's a bad example

StackMeter

@RedwolfPrograms lolololol

however

that is not why I came

I came to give advice on this

Redwolf Programs

2:56 PM

StackMeter

  def primeFactors(num):
    while not (isPrime(num) or num < 2)
      i4 = 2
      list1 = []
      if num % i4 == 0:
        factors.append(i4)
        num = num // i4
        i4 = 2
      else:
        i4 += 1
      if isPrime(num):
        list1.append(num)
  return list1

Redwolf Programs

Uh...it's 28 bytes in JS lol

Oh that's prime factors

StackMeter

yes

Wzl

@StackMeter edit, remove backticks, press Ctrl-K or click "fixed font", enter

otherwise it's invalid python

StackMeter

done

ignore the spacing

Redwolf Programs

3:00 PM

Ugh, we have no normal prime factors challenge

I agree with Redwolf and rak

I was able to use codeanywhere on my school network even though they block SSH, because the connection to CA is HTTPS and CA uses SSH with the server

CA isn't free though, and idk if you can still use it; i got an account before that and i apparently can indefinitely have a free trial as long as I'm only SSHing into an existing server

No.
