Can someone upvote this answer, so that Community doesn't bump it? ಠ_ಠ

Bumping is one of the most annoying things, especially when its on questions with a status tag :/

Wezl programs redwolf

does downvoting work :P

caird coinheringaahing

I don't believe so, it bumps anything with no positively scored answer :P

I'd do it myself, but...

Wezl programs redwolf

oh, I understand. My password is

hyper-neutrino

it bumps if the maximum answer score is 0

that is, there must be at least one answer, no answer may have a positive score, and at least one answer needs to be neutral

if all answers are downvoted it no longer gets bumped

according to this MSO post

Q: Sum of the first 1000 pairs' product of sexy primes

i would like to ask how to find the Sum of the first 1000 pairs' product of sexy primes. I can find the sexy primes pairs from L to R. But I don't know how to find the first 1000 pairs. And how do I sum it? Thank you.

primes

emanresu A

CMC: ^

With number of pairs as input

( I have 14 in Vyxal)

hyper-neutrino

this is not very clear

sum(x * y for x, y in sexy_prime_pairs) ??

emanresu A

Yes

lyxal

@emanresuA is the answer for 10 146?

emanresu A

No, it's 8794

[5,7,11,13,17,23,31,37,41,47] is the first ten sexy primes

[[5,11],[7,13],[11,17],[13,19],[17,23],[23,29],[31,37],[37,43],[41,47],[47,53]] is the list of pairs

Then [55,91,187,247,391,667,1147,1591,1927,2491] is the list of products, and the sum of that is 8794

lyxal

3:08 AM

Oh wait lol I was generating it all wrong

@emanresuA flagless?

emanresu A

Yes

13 with flag

lyxal

14 flagless, 12 with 1

emanresu A

I have 14 flagless, 12 with 2

What do you have?

lyxal

λ6+"æA;ȯƛ6+* with s

You?

emanresu A

Wow

That's pretty much exactly what I had

lyxal

3:11 AM

What flags?

emanresu A

Except : instead of ƛ

Wait nvm, I thought ȯ didn't work the other way round

No r needed

hyper-neutrino

13 flagless

lyxal

@emanresuA nice

@hyper-neutrino yeah I was about to comment that

hyper-neutrino

13

or equivalently, 13

same 12 with s flag by just dropping the sum off the end of the former

emanresu A

Dot product? Nice

#1 is what I had

lyxal

3:15 AM

@hyper-neutrino why is there a byte count for the input?

hyper-neutrino

¯\_(ツ)_/¯

emanresu A

Do you want me to install vylight on vyxapedia?

lyxal

You'd have to change the colours a bit

They currently work well on the dark background of my site, but they may not work as well on the white background of vyxapedia

emanresu A

Yes

Fortunately I have a nice stylesheet

hyper-neutrino

13 in Jelly

emanresu A

3:18 AM

github.com/Vyxal/Vyxal/blob/master/static/css/style.css

hyper-neutrino

i mean, does anyone use my site other than myself

everyone still just uses tio#jelly or lyxal.PA lol

emanresu A

Yeah

lyxal

@hyper-neutrino I'd use the jht site for jelly

emanresu A

^

But I know all the useful Vyxal builtins and Vylight is nice

lyxal

And if the on screen keyboard was nice, I'd even use vyxapedia

hyper-neutrino

3:22 AM

lol yeah i need to fix that for mobile

for me the main appeal is being able to type everything without needing to copy-paste

emanresu A

Guess what the third-most-used language tag is?

Unrelated String

the one reason i prefer tio over your site is i can't see much output without scrolling down too far to click the run button

hyper-neutrino

though this is more relevant for jelly where I actually know some of the built-ins

Redwolf Programmed

Is anyone working on a 4th blog post?

lyxal

@hyper-neutrino One thing lyxal.pa has that vyxapedia doesn't have is epic codemirror stuff like multiple cursors and autoindent - stuff that people definitely use when they code golf

caird coinheringaahing

3:26 AM

@RedwolfProgrammed I believe both WW and DLosc mentioned some interest in doing so, but I'm not sure how that's going

hyper-neutrino

you have multiple cursors??

lyxal

@hyper-neutrino yep

hyper-neutrino

ok that's really cool

lyxal

Basically everything a code mirror editor would have

@lyxal cool,we should have keg for the lotd

Adám

@PyGamer0 It is a fairly simple automaton. We've seen many such challenges. How about prohibiting pieces from hanging in the air, instead specifying that they fall down?

PyGamer0

@Adám hmm ok

Adám

@PyGamer0 What do you mean by "we randomly remove the ones"?

PyGamer0

@Adám lemme fix that lol

done

Adám

5:12 AM

@PyGamer0 "(i use @ for this)" should be expanded to say that here, you're using @ to indicate which pieces will be removed, but that the answer shouldn't indicate this.

@PyGamer0 "NOTE: The bottom most rock particles are touching the ground, hence we don't count these particles." seems to contradict that there are @ on the bottom row.

@PyGamer0 You still haven't explained what "Then we randomly remove the rock particles" means. Does each particle have a 50% chance of disappearing? If so, say that. I also don't like this aspect, as it throws in randomness for now real reason, and makes it hard to check/compare answers.

@PyGamer0 You should explain what you mean by "care about gravity", i.e. that if any particle ends up not touching any other along a side (not diagonally) or the ground, it falls down (but how far? until it touches a side or until it rests on something?)

PyGamer0

5:45 AM

@Adám no they are touching air on the either side

Adám

Ah. Maybe explain?

PyGamer0

@Adám i think i fixed most of those things

Adám

Looks pretty good now. You might want to proofread for spelling and punctuation, and I still think the randomness isn't worth it, as it prevents test cases, but it isn't bad as-is.

PyGamer0

i think its safe to say that this is now wrong

No, I'll add that

@emanresuA Can a and/or b be empty?

@emanresuA Test case with negative numbers or restrict to positive.

emanresu A

@Adám Restrict to positve, no zeroes, no empties.

Adám

@emanresuA Care to explain why overlaps shouldn't occur?

emanresu A

6:58 AM

Simply because I didn't want to overcomplicate the challenge and/or cause ambiguities.

If you remove them one-by-one, then you'll end up with some left.

Yeah, more fun.

@emanresuA What?

emanresu A

It's annoying me, and <pre><code> works for multiline even with html tags.

But then the grey areas are wide.

The real problem here is that SE increased the line height ⍨

apparently there's a JavaScript variable that has the property x == null is true, although x === null is false and x === undefined is false. Note that null == null is true (obviously) and null == undefined is true.
