@BetaDecay It's your challenge so it's up to you. I just thought since it's not the main part of the challenge it might invite more golfing opportunities to leave it open

Beta Decay

Yeah, but I agree that it might be confusing

i dont have a ranged weapon, so i just waited for the floating eyes to go in a room to pass

Put on a blindfold!

@quartata Nope, but that doesn't stop me from giving bad advice.

Is that a good thing?

TùxCräftîñg

yes

quartata

So you inadvertently gave advice that makes sense

That's why I asked because I thought you were serious

TùxCräftîñg

but the telepathy only work when blind

That's why you use a blindfold

A: Can numeric input/output be in unary?

Yes, but only for languages such as sed, Retina, ///, etc. Only where it is the language's most natural integer representation. I'm in general a fan of taking input in the most natural format for a given language. If a language has no integer type / integer processing capabilities, then the mos...

What do the isosurfaces behind a fan look like? That is, if we have a fan running, the air in front gets pushed away in a column, but the air being drawn into the fan comes from all directions. So, looking at the points where the air speed is roughly the same, do they form a spherical distribution, or some other shape?

flawr

@El'endiaStarman Yep more or less spherical.

El'endia Starman

Some graphical evidence would be awesome.

@El'endiaStarman yeah :D

Input in unary is a joke to me but anyway

El'endia Starman

@flawr That's pretty cool.

TùxCräftîñg

wat

sounds made by my phone are outputted by my computer speaker o.o

El'endia Starman

@flawr I don't think I ever wondered this specifically, but I have always found it somewhat strange and cool that there's such profound asymmetry.

flawr

@El'endiaStarman Haha, I never thought of it as an asymmetry:)

But I did do quite a few expriments / a lot of reading about vacuum cleaning a while ago, for making and later improving a cyclonic dust separator. (The chips from the planer kept clogging the vacum cleaner) (something like this but smaller)

@HelkaHomba true. I wasn't being real serious tho

TùxCräftîñg

ETHproductions

@TùxCräftîñg most any made-up word or acronym will be hard to explain to new users

TùxCräftîñg

it's a acronym

"Wirte a POF that..."

AFAIK there is a html tag to explain acronyms

flawr

that's why I think "submission" is pretty clear

TùxCräftîñg

just idk the tag

What's wrong with just writing "submission" instead of "functin or program"

?

El'endia Starman

@flawr Oh cool. So cyclonic vacuums work better because you don't have material bunching up and clogging it (at least, it would be harder to do so)?

TùxCräftîñg

wait

straw dont even have a reverse string function o.o

Having decimal numbers is probably infinitely more important

El'endia Starman

@TùxCräftîñg You can make one from popping and concatenation functions.

zyabin101

9:07 PM

@El'endiaStarman How? :3

TùxCräftîñg

@El'endiaStarman look hard to do

El'endia Starman

@zyabin101 Same way you'd reverse a number!

zyabin101

:D

flawr

@El'endiaStarman Exactly, but as they are no perfect it is still advisable to use a filter. In my setup the air goes through the cyclone first, and then through the vacum cleaner, that way the bag in the vacuum does not fill up / only does the filtering for really fine particles.

And you can use a container of arbitrary size below the cyclone.

So that is really convenient=)

El'endia Starman

Yeah, sounds like it.
