Rx | the Rx schema and validation system

I am trying to link Cortex-M4 firmware with clang + lld. The gcc build works fine. I am using the stock CMSIS linker script with only RAM & ROM size adjusted (bases are the same). Beginning of the script (without comments):

I've installed Windows 10 21H2 on both my desktop (AMD 5950X system with RTX3080) and my laptop (Dell XPS 9560 with i7-7700HQ and GTX1050) following the instructions on https://docs.nvidia.com/cuda/wsl-user-guide/index.html:

1. Install CUDA-capable driver in Windows
2. Update WSL2 kernel in PowerShell: wsl --update
3. Install CUDA toolkit in Ubuntu 20.04 in WSL2 (Note that you don't install a CUDA driver in WSL2, the instructions explicitly tell that the CUDA driver should not be installed.):

I have the initial state of tree diagram that I'm building, with collapse animation and custom node design but whatever I try to make the tree vertical instead of horizontal I mess something else (animation not working well, the lines are wrong and other problems).

I'm trying to visualize a merkle tree where a vertical display is more intuitive. unfortunately I dont have strong background in front-end or deep understanding of d3 lib.

Here is the code:

Is there a Subject implementation in Rx.NET that functionally resembles BehaviorSubject but emits the next value only if it has changed?

I'm rather new to Reactive Extensions and I can't seem to find anything like that, although this pattern feels like a natural replacement for INotifyPropertyChanged.

My naive implementation is to encapsulate BehaviorSubject like below. Is there any disadvantages in this, compared to creating a composable observable with Observable.DistinctUntilChanged?

I am trying to make it so that the turtle is hidden from the beginning of the program but even after putting t.hideturtle() right below where I declare the turtle as variable t the turtle still seems to show up in the middle of the drawing.

I have a in my HTML page and I would like to use that image as a border.

What I find online is that you can add in CSS:

I want to implement an executor. I want to store the thread handle in a struct, so I can join it later, waiting for the threads to stop gracefully.

But I get an error when I try to call the join() method. I would like to know the reason and how to fix that.

I am using Python 3.9.7 with pynput, I wanted to retrieve the x and y position of mouse both clicking and releasing separately and saved it into variables outside of the function on_click (e.g: px = x position when pressed, rx = x position when released) for other function usage

The code are as follows , code are modified from Pynput documentations:

Question: I want to fade / highlight a whole dependency chain, based on the link type.

To do so I utilize the mouseEnter event, which currently store all links and nodes. Further I fade all nodes and links and only highlight those nodes which where filtered as related nodes and links. It would require to check all related nodes and links again, if those have connections from type need too. This must be done as long as dependency connections are found.. I can´t figure out a proper algorythm.

Examples:

For better understanding I created a beer ingredients dependency, which looks lika a star. For those purposes my version is fine. BUT the second chain, about car -> wheel -> tires -> rubber and the radio is giving me headache. The radio is a "use" dependency, means its not mandatory for the chain and shouldn´t be hightlighted.

Expected result:

If the cursor is over car all connected nodes with a "need" dependency should be highlighted and the rest should fade.

For those who wants to help me with, please dont hesitate to ask, if anything is unclear.
