noise | simple framework to build tools | Application Framework library

In Jetpack compose, we have the option of using rememberCoroutineScope() as well as using the LaunchedEffect composable in order to use coroutines / run suspend functions (show snackbars etc).

The convention I've adopted so far is to remember a single coroutine scope at the top of my compose tree, and pass it down via function arguments to places where it is needed. This vaguely seems like a good practice, but on the other hand it's adding extra noise to my function signatures.

1. Are there any reasons for preferring the use of LaunchedEffect over rememberCoroutineScope() inside composable functions?
2. Is it worth the effort to only create / remember a coroutine scope once per compose tree, or should I just call rememberCoroutineScope() in each function where a coroutine is actually launched?

My problems seems simple, I am using ggplot2 with geom_jitter() to plot a variable. (take my picture as an example)

Jitter now adds some random noise to the variable (the variable is just called "1" in this example) to prevent overplotting. So I have now random noise in the y-direction and clearly what otherwise would be completely overplotted is now better visible.

But here is my question:

As you can see, there are still some points, that overplot each other. In my example here, this could be easily prevented, if it wouldn't be random noise in y-direction... but somehow more strategically placed offsets.

Can I somehow alter the geom_jitter() behavior or is there a similar function in ggplot2 that does exactly this?

Not really a minimal example, but also not too long:

This sounds like an easy task, but I already spent hours on it. There're several posts with a similar headline, so let me describe my problem first. I have H264 encoded video files, those files show records of a colonoscopy/gastroscopy.

During the examination, the exterminator can make some kind of screenshot. You can see this in the video because for round about one second the image is not moving, so a couple of frames show the "same". I'd like to know when those screenshots are made.

So in the first place I extracted the image of the video:

I have the following code in an Excel VBA module:

dear stackoverflow community,

I have now idea, how i can create a Low-Poly 3d Terrain in Libgdx,

By googling i found remains from the libgdx blog or website they can't help me, but by the research nothing what can help me.

I create a Value Noise but it does not work and i think its not the right way to do it.

Do you know a good tutorial or websites? ^^

As seen on the picture, I need a math formula that calculate the red circled point with cartesian coordonate that will make equidistant lines. It is not simple trigonometry I guess...

My goal is to be able to calculate cartesian point around half of the circle and trace my lines from it.

Using p5js, I'll use random value from Perlin noise mixing it with sin or cos (whatever...) to trace my lines from those points. At start it's a math problem, the rest should be pretty easy for me since I already have a good base that work, but need to be optimized with this math.

Any clue ?

Context :

• A game which features dozens of units capable of doing many different things which make noise.
• For more realism, the sounds are mixed together with gain nodes and panner nodes to take space into account.

This approach generates hundreds of nodes at runtime.

It's not a audio mess only because depending on the positions of the units and the camera most of them actually have a zero gain.

It works just fine on my hardware, but I would like the game to be able to run on low end hardwares.

Can I stay with a lot of nodes with a zero gain, or do I have to optimize upfront and present only nodes with a non zero gain to the web audio API to avoid performance issues ?

I can't find any information about limits in the documentation...

In TTN they are no longer supporting large decoders.

I know what the decoder needs to be in TTN, it is in my DECODER function, but dont know how to execute it in the function node.

If you use inject Payload [1,2,3] RAW, it injects the raw payload that is msg.payload.payload.uplink_message.frm_payload into the decoder.

The DECODER needs to decode the raw payload and output it in msg.payload.uplink_message.decoded_payload

If you use inject Payload [1,2,3] Decoded in the flow you see how the end result needs to look like and the decoded msg.payload.uplink_message.decoded_payload

I am still learning JavaScript.
