Question about rhythm notation

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 :)

I made an app that identifies chords using Roman numeral notation

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.

How do you get better at visualising/memorising notation?

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?

Die notation

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!

I am an amateur chess player who is not very good and is very interested in improving. I recently started on chess programming and I'm having some problems with notation.

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.

[Question] Do notation to map a [Maybe Int]

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 &lt;- foo
i &lt;- mb
[Just (i+1)]

{-
i &lt;- mb
^^
Couldn't match type βMaybeβ with β[]β
-}
``````

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 &lt;- foo
return \$ Just \$ i + 1
``````

In my previous post I got so many comments to first teach programmers some basics like Big O Notation and similar thing; For the same I wrote a blog containing all basics Data structure; Hope it helps. [7 MIN READ].

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 listsΒ 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.

Letβ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 nodeβs next reference to the next node
4. Assign the current nodeβs next reference to your new node

Disadvantages of linked lsit:

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

Variable names and scientific notation

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 Β§ 3.333 he writes:

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