Notation

I was trying to explain the concept of abuse of notation or abusive math to a friend but I couldn't come up with any examples. What are some of your favourite examples of this?

So, I'm experimenting with this new idea of mine. And the rhythm goes like this: one-two-three-four one-and-two-and-three-and.

Normally, I would notate that as 7/8, but in this case 4/4|3/4 seems more appropriate to me. So, is it ok to do that or will I be punished by the music god?

Thanks :)

Hi! First time poster here. As a music theory student, I've always had the thought that a tool that can show you in real-time what chord is being played would be really useful - especially in remote settings, where audio quality might be a problem. So to improve music theory instruction during COVID times, I developed a desktop app that can display chords you play on a MIDI keyboard, using Roman numerals and figured bass. I've scoured the Internet for such a tool but could not find one, so I decided to make one myself - and made it open-source.

Using this app would, naturally, require you to own a MIDI keyboard. Also, note that the app itself doesn't generate any sound, so you would need to combine it with some notation software like Musescore to actually hear some sound. The app does, however, also include a simple keyboard visualizer if you find it useful.

Being a music theory student, I know my knowledge of music theory is limited, so feel free to point out any mistakes I made! I also welcome any feedback, as I hope to expand this tool to encompass more chords and features.

If you're interested, here is the link to my github repository. Simply head down to the Downloads section to give it a try. It supports macOS, Windows, and Linux.

When I read up on certain moves or openings, it will always have a bunch of notation, letters and numbers next to each other that signify certain moves, and I can never really get my head around it. I always need to see it visually on a board. Likewise, even if I'm looking at a board and I see a particular square I wanna go to, it'll take me a few seconds to line up the file and rank in order to get the notation for that square.

How do I improve so I can do such things quicker, and be better at reading chess positions when it is merely in written form?

Hi! I’m new to chess, and I don’t know how to convert algebraic notation to descriptive. I’ve tried some websites but they didn’t work. Can anyone help me convert this match? Thanks for any help.

Hi

I'm very new to RPGs and am currently preparing a game for some friends. Reading through the material I came upon a Die notation I'm not familiar with. I've tried googling it but can't really find an answer, or perhaps I just suck at googling.

The notation is as follows:
6+1D4+2

I'm familiar with the 1D4+2, like roll a D4 and add 2, but the first part confuses me. If I should add 6 why not just write 1D4+8. Can someone please clarify?

Ps. if it matters this is for "The Haunting" - Call of Cthulhu and in context the text is:
"The attack inflicts 1D4+2 damage, or 6+1D4+2 if an Extreme success is rolled"

Thanks!

What the title says. I've been using Musescore for years for fun and I have one choral piece that I plan on publishing (it's on a laptop that is not with me at the moment). Until I get that one back, I'm using my sister's laptop to work on another piece. I'm considering Musescore since it's familiar, but I'm curious about the other alternatives. As far as free notation software, what would you recommend to me?

I have been learning the ipa, and have been wondering if

/ ðə ɪnt.ɜː.næʃ.nəl fə.ne̞.tɪk æl.fə.be̞t /

is correct for

"The international phonetic alphabet."

In my mind, if I've been doing something for the past ten minutes I go "oh, I should have done this ten minutes ago!" and "wow, you've been doing this for ten minutes, I think I should have done this ten minutes ago!". I want to know how to get through this problem so that I don't make the same mistakes.

In this post I'll give my current version of notation:

>A1=A1+A2

I want to know how to get through this because I have been going into more detail with my moves lately. I've been thinking about it a lot and I've found a few other alternatives:

>A1=A2+A3

>A2=A1+A3

>A3=A1+A2

>A2=A1+A3

My question is, how would you write my move? In this notation, when you have A1=A1+A2 and you have A2=A1+A3, you are doing a combination of A1=A1+A2. In my mind, I can't see how to write my move so that it is just A2.

I also found that in this notation, if you can figure out and explain it yourself, it is not the same notation as A1=A1+A2.

Any help would be appreciated.

Hi,

I'm trying to understand do notation. I want to map a [Maybe Int] . However I got an error on mb .

foo :: [Maybe Integer]
foo = map Just [1..10]


incrFoo :: [Maybe Integer]
incrFoo = do
    mb <- foo
    i <- mb
    [Just (i+1)]

{- 
    i <- mb
         ^^
    Couldn't match type ‘Maybe’ with ‘[]‘ 
-}

There is certainly a better way to do this, however I want to understand do notation

Any Idea ?

Thanks in advance ?

EDIT : I choose the following implementation

incrFoo = do
    Just i <- foo
    return $ Just $ i + 1

Quoting from Wikipedia: >In East Asian cultures, particularly China, Japan, and Korea, large numbers are read in groups of myriads (10,000s) but the delimiter commonly separates every three digits.

Isn't it counter intuitive for korean people to write (and read) numbers in a different way than they say it? Or they just get used to it and don't even notice?

Hey r/ProgrammerTIL. In October 2020I posted this and you'll be seemed to like this. I have published this list you're about to see below on diamondcoder.com and it was very well received there. I am hoping you'll find some value in this as well. Full article is below and if you want more of this kind of thing then please visit here or you can follow me on reddit. I have also written a blog containing the list of algorithms you must consider learning. Click here to read

1.) Linked List :

Linked lists offer some important advantages over other linear data structures. Unlike arrays, they are a dynamic data structure, resizable at run-time. Also, the insertion and deletion operations are efficient and easily implemented.

Let’s take an example that your program expects some input from the user. Now there are 3 possible scenarios: 1. You and and your user both know the size of input, in this case go for array as it has fastest insert, search times. 2ndly you may not but user may know the size of input. Then you can ask for the size and then declare array of that size dynamically.
But if your user also does not know the input size (It may happen, think you are writing a text editor)?
You may declare a huge array, but still there is chance of overflow, or huge wastage of space.

Linked list here comes into play, you allocate one unit of space at a time and link it with a new one when required. This helps you to optimize space.

Linked list has got another advantage that is as the space needs not be contiguous, chances of space unavailability is quite less, which happens in case of large dynamic array allocation. Time and Algorithmic advantages are also there.

Advantages of Linked list:

1. Find the spot in the list
2. Create a new node
3. Assign the new node’s next reference to the next node
4. Assign the current node’s next reference to your new node

Disadvantages of linked lsit:

More memory is required to store elements in linked list as compared to array. Because in linked list each node contains a pointer and it requires extra memory for itself. Elements or nodes traversal is difficult in linked list.

I am using the R programming language. I used the "rpart" library to fit a decision tree model on some data:

library(rpart)

car.test.frame$Reliability = as.factor(car.test.frame$Reliability)

z.auto <- rpart(Reliability ~ ., car.test.frame)

plot(z.auto)

text(z.auto, use.n=TRUE, xpd=TRUE, cex=.8)

As seen here, the labels of the "Country" variable are replaced with "b, e, f, g, h". Is it possible to replace these labels with their actual values (e.g. Korea, Sweden, Mexico, USA, Germany)?

I understand that there is a library "rpart.plot" that has more comprehensive visualization capabilities, but I am using a computer that has no USB port or internet access, thus I have no way of downloading this library.

Just using the "rpart" library, is it possible to change the labels from "b,e,f,g,h" to the actual Country names? In the visual output, is it possible to change numbers from scientific notation to regular notation?

Thanks

Hi folks! My problem is simple: I do not know the system of notation Wittgenstein uses in the TLP. For example in § 3.333 he writes:

"[...] Dies wird sofort klar, wenn wir statt „F(F(u))“ schreiben „(∃φ) : F(φu) . φu = Fu“. Hiermit erledigt sich Russell’s Paradox."

I do not know this formal system and the dots are confusing me. I find this frustrating, especially because of the following § (3.334). ^^

Could you please either explain what the dots mean or just give me the name of the notational system, so that I can learn it by myself?

Thx!

A quote from https://www.scoringnotes.com/news/musescore-3-6/:

>Of particular interest to music notation aficionados is the release of a brand-new, SMuFL-compatible music font called Leland, designed by MuseScore lead designer Martin Keary in collaboration with music engraver Simon Smith. Drawing inspiration from the look of scores produced by the legendary SCORE program and its creator Leland Smith, Leland is the new default music font for MuseScore beginning with the 3.6 release.
>
>Paired with Leland is a new text font heavily based on New Century Schoolbook called Edwin, which is the new default MuseScore text font. Both Leland and Edwin are free, and they are released under open font licenses.

As far as I know, technically there are only Satoshis. Respectively, technically it has no name, but we call this basic unit Satoshis to honor the inventor, correct? But who said back then that 100 million of these units is 1 "bitcoin"? Was it Satoshi himself?
