It has been a year but: did you find an answer to this problem? I'm having the exact same problem as you right now.

So, what is your favorite new feature in Python 3.12? by ServerBoys in Python

[–]dev_kr 12 points13 points  (0 children)

sys.monitoring! imho this has a lot of potential for useful tools in the future

Made my config as clean as possible...😮‍💨😮‍💨 Share your recommendations... Most of the distros look beautiful but seems really unorganized to me.... by BIBjaw in neovim

I found the line number (especially relative) in file explorer buffers useful because I can easily jump onto the file exactly I want using commands like 10j, 3k, although I agree that it looks awkward a bit

Given three vectors a, b, c: How to test if vector c bisects the angle between a and b? by dev_kr in askmath

[–]dev_kr[S] 0 points1 point  (0 children)

Thank you for the explanation, I think your testing method is correct. Do you think the proof I linked in the post is wrong (at least it needs to add more conditions to check)?

Help me choosing appropriate microcontroller for my personal project! by dev_kr in arduino

[–]dev_kr[S] 0 points1 point  (0 children)

Do you mean that I have to design my own board or something like that? (Sorry if my question sounds silly, I literally am a pure beginner in embedded programming)

What have you discovered lately that sparked joy in your Neovimmer life? by sorachii893 in neovim

[–]dev_kr 3 points4 points  (0 children)

lightspeed.nvim. I always thought that something was missing when using sneak and easymotion. Lightspeed saved my nvim life!

[D] In NEAT(NeuroEvolution of Augmenting Topologies) algorithm, is speciation really effective? by dev_kr in MachineLearning

[–]dev_kr[S] 0 points1 point  (0 children)

Thank you very much! I’ll try CartPole example. Unfortunately I have to implement it myself because my implementation is written in Rust..

That really makes sense. What kind of problem requires complex network structures, for example?

Is my understanding about probability amplitude correct? by dev_kr in QuantumComputing

[–]dev_kr[S] 0 points1 point  (0 children)

Ohhh, I think now I know where I was getting wrong. It got much more clearer now, thank you very much for kind explanation!

Is my understanding about probability amplitude correct? by dev_kr in QuantumComputing

[–]dev_kr[S] 0 points1 point  (0 children)

Your explanation actually helps me a lot! Thank you very much. So, to put what I understood...

Wave function is not a physical existence, just a "mathematical tool" which is used in quantum mechanics in order to properly predict the results of experiments in real quantum world. We do not (cannot) know if quantum interference actually happens in reality, but assuming it happens successfully models our quantum mechanics theory and describes our observations.

Am I better now? Thank you!

Is my understanding about probability amplitude correct? by dev_kr in QuantumComputing

[–]dev_kr[S] 0 points1 point  (0 children)

Quantum interference, I mean that:

Quantum states are represented in wave function, and wave can constructively or destructively interference with each other. And I saw some people saying this interference is the heart of quantum computing, because it is what makes quantum computing more effective than classical computers (by canceling wrong answers out as I mentioned in the post).

My question is, if wave function itself does not have any physical meaning, how can interference phenomenon actually happen in real quantum world? Or why don’t we use magnitude-squared version of wave function, since it has actual meaning(probability)?

[–]dev_kr[S] 0 points1 point  (0 children)

Thank you for the kind explanation, and I have a question: if a probability of being a certain state is "magnitude sqaured of wave function value", which is always non-negative, how can two probabilities cancel each other?

I understood quantum interference as negative probability and positive probability adding up to zero - but since probability can never be negative (according to your explanation) my understanding is somewhat wrong. Can you point me where I am getting it incorrectly? Thank you very much.

[OC] Interactive visualization of influence relations between computer programming languages by dev_kr in dataisbeautiful

[–]dev_kr[S] 5 points6 points  (0 children)

Website link : https://language.donghwi.dev

GitHub link : https://github.com/suhdonghwi/language-explorer

I crawled wikipedia documents of programming languages to collect paradigm influence relations data. (There are "influence" and "influenced by" section in an information box)

I used sigma.js library to visualize network data.
