Oh, I thought this was some sort of game of life

J.S. Bach - Passacaglia and Fugue in C minor BWV 582

speaking of organ...

@flawr You mean you can program a key to play a note or set of pipes it wouldn't normally play? (Like rearranging the strings on a piano)

8:13 PM

@flawr this

@HelkaHomba no

@HelkaHomba a note is a sum of frequencies

mbomb007

@MamaFunRoll Yeah, ambigrams are cool. They would make an interesting topic for a challenge, if you could think of something.

many different sums of frequencies can comprise the same note

that's why you have different instruments

ok

@HelkaHomba There is no such thing as normally, you have to choose which sets of pipes one keyboard is playing.

mbomb007

8:14 PM

Like take two words, and see if they can be made into an ambigram...

when a piano plays an C3 it sounds different than when a violin does

of course

@Optimizer it's not obvious at all when you think about it

C3 is supposed to be a frequency

how can the same frequency sound different?

Each of the levers to the side is *one* kind of pipe. If you pull it out it is activated: https://www.youtube.com/watch?v=D2dmENYHwyw

(Some sets can only be played by specific keyboards.)

@orlp speed.. wavelength ..

8:16 PM

@orlp I agree. Pianos and violins both just have taut strings that make sound. I can't really say why they are so different

@flawr aren't there also levers that reduce/increase air pressure

@HelkaHomba you should accept an answer to this question

@orlp I've never heard of an organ that lets you actually do this manually?

@orlp also, you cannot really think that its just pure C3 sounds coming out.. right?

@Optimizer (I know the answer, just trying to make other people think)

8:17 PM

what is the answer then?

roughly speaking, the mind really listens to the lowest frequency in a sum

higher frequencies form a 'color' of the note, rather than changing the perceived pitch of the note

oh.

Do you guys know where I can go to work out which SE a question can be asked?

I could not have explained it any better.

how this works with chords I don't really know tbh

since, in the end, a chord is just a sum of frequencies as well

8:20 PM

@muddyfish What do you mean?

@Optimizer the mind especially ignores multiples of the base frequency

You mean on which site a question is on topic?

@AlexA. I've got a question and I don't know where it would be on-topic

@muddyfish I think the standard approach is to ask on metas that seem like they could fit until people stop comparing your intelligence to aquatic life.

2x, 3x, 4x, 5x, etc

8:20 PM

What's everyone's favorite song on this list kickassclassical.com//… ?

and frequencies close to this

@HelkaHomba I have a lot of favourite songs

Any other ideas?

the song I linked above ranks really high

@muddyfish If I'm not mistaken, Meta.SE has or used to have a tag for site recommendations

I really love most of chopin's works, especially the nocturnes

Our first ><> question on CR

Welcome to h><>ll

8:23 PM

@AlexA. hfishll?

Fun fact: the "ringback" tone played on your phone (when you've made the call and the other end is ringing) is actually two tones played simultaneously that your brain modulates into a brr-rrr-rrr-rrr noise

Ringback tone

A ringback tone (RBT, alternatively ringing tone) is an audible indication that is heard by the originator of a telephone call while the destination being called is ringing. It is normally a repeated tone, designed to assure the calling party that the called party's line is ringing, although the ring-back tone may be out of sync with the ringing signal. The ringback tone may be generated in the distant switch and transmitted in-band. In analog networks the caller could therefore monitor the quality of the complete voice path of the connection before the call was established. The distant switch...

Why do many sites suddenly have "cookie policies" now?

There was a EU law about that passed last year if I recall correctly

Blame the EU.

Right to be forgotten

The right to be forgotten is a concept discussed and put into practice in the European Union (EU) and Argentina since 2006. The issue has arisen from desires of individuals to "determine the development of their life in an autonomous way, without being perpetually or periodically stigmatized as a consequence of a specific action performed in the past." There has been controversy about the practicality of establishing a right to be forgotten to the status of an international human right in respect to access to information, due in part to the vagueness of current rulings attempting to implement such...

Basically, you can file a motion to the courts to make Google stop linking to a specific page if it contains information about you that you don't like.

Because if Google can't find it, it clearly doesn't exist.

Also, the EU gets to control all of the Internet.

8:45 PM

So what if Google links to a page that has a link to a page that has content you don't like?

@TimmyD Take it down!

I'm morally opposed to content on the Internet

@TimmyD "This is Timmy, he finds links to content he doesn't like, he trys to avoid them, even if he opens by accident, he closes the tab and moves on. Timmy is smart. Be like Timmy"

Take the whole thing down! The EU gets to decide what Google is allowed to link to, because wheeeeeeeeeee.

BTW the links only get taken down for residents of the EU

Theyre still visible for people outside

8:48 PM

@muddyfish No.

I'm pretty sure thats how it works?

No it isn't.

The search results will be hidden for everyone and a short notice of removal is given at the bottom of the goole search page.

@TimmyD It's not that it's content you don't like, it's that it's content about you that you don't like. Maybe it's not a perfect solution but I can totally understand why people wouldn't want to be publicly slandered.

Ok then, didn't know that

El'endia Starman

8:51 PM

Is there not a way to masquerade as someone from outside the EU, and thereby get content that way?

Also you can't remove any content, just content that would have very negative effects on you personally.

@El'endiaStarman Google doesn't show the result. The content is still there.

El'endia Starman

@mınxomaτ But if I can find it on Google from the USA, then can't you (in some way) pretend to be from the USA, and thereby find it on Google?

No.

so.. google takes down any link that you don't like in EU?

woohoo, I'm getting a bunch of rep from Calvin's accepts

8:53 PM

@Optimizer They decide on a case-by-case basis.

@aditsu lucky

@El'endiaStarman I think you can't find it in the USA. Spoofing your location would be easy with tor or something

=P

9:48 PM

I still haven't been formally told that commas and dots are switched in german

Compared to what?

English, my native language

So what is your challenge going to be about?

well, scientists tend to use the term "proof" in their papers not-so-frequently compared to people that aren't so informed about science

@Zwei btw: en.wikipedia.org/wiki/Decimal_mark#Examples_of_use

9:50 PM

for instance, people actually doing research will never claim to have "proof" against vaccines causing autism, but anti-vaxxers will claim all day that they have "proof" for it causing autism.

the challenge is to count the occurences of any form of the word "proof", and compare it to the overall word count and check if the ratio is above a certain threshhold

return some form of truthy value if it is, and some falsey value if it is not.

That's pretty trivial

the idea is that the truthy value represents a potentially scientifically invalid argument

Is the goal coming up with this threshhold? Otherwise the challenge sounds quite simple, as many languages have builtins for counting occurences or similar stuff.

poi830

^

no, the threshold would be something I haven't decided on yet

9:53 PM

The "idea" has no effect on the challenge at all.

It would probably be a dupe of this challenge then.

Well, it may get a bit more complicated in that you have to find all the forms of proof. This includes "proof", "proved", "proven", and "prove"
