Some sort of "Lemmy dev community" where devs hang out.
Something like the communities on the @programming.dev instance?
A Tolkien based active community would be great. Reddit had/has a few that were fairly active. There are communities here but really not active at all.
Also wish the NBA community was more active - quite frankly surprised it's not.
Digital signal processing
I.....think I may be interested in learning about that?
DSP (digital signal processing) is the field of applied mathematics and engineering dedicated to transforming and manipulating digital signals.
Examples of real digital signals include audio files, image files, video files, and digitized recordings of various physical quantities by computers like the configuration of a robot as it moves in time, measurements of the processes in a factory, the trajectory of a spacecraft — almost anything that can be periodically sampled and take on a finite set of values [1] can be seen as a digital signal.
DSP includes using tools like the Discrete Fourier Transform (DFT), the Z-transform, wavelet analysis, probability, statistics, and linear algebra to do things such as filter a signal (example: audio equalizer), predict future values (example: weather forecasting), data compression (example: JPEGs), system identification (example: fit a model of the earth to predict seismic activity), control (example: make a DC motor to respond to position commands), and stabilization (example: keep plane from "wanting" to smash into the ground). Particularly, it requires a careful consideration of the effect of sampling a signal (example: if done carelessly, you can make the sampled system unstable [read: explode]), as well as an interpolation process of some kind if you plan on using that signal outside your computer (example: you want to hear an audio signal stored on your computer).
I got into DSP because I was an audio engineer and musician [2], and I wanted to design my own audio plugins. IMO I think almost everyone would benefit from some knowledge of DSP, but the math is really intense. Personally, I found out late in life that I have a nearly infinite appetite for math, so it's a good fit for me.
Here's a playlist about DSP if you're interested.
[1] Actually, a lot of basic DSP books don't restrict the signal to be in a finite set because it makes the math easier if the signal could be any real number. However, certain structures that would be exactly equivalent in theory are not equivalent on a real computer because ordinary computer arithmetic is approximate.
[2] I still play music, but not as much as before engineering school.

I miss r/livesound. It was a fantastic resource and a very active community.

Desperately needs more upvotes
My niche interests.
- Nim-lang (this has some activity here, though I often have federation issues)
- Raylib
- low-poly+untextured polygonal art and vertex colors (both 2D and 3D)
I don't really consider myself an artist or a programmer (I haven't done much), maybe there's a fediverse instance that could work for me but it's probably too niche even just with those communities.
You might give the programming.dev instance a try for the first couple subjects, as they have an open !programming@programming.dev community that may work for them.
The problem is that they overlap, usually all 3 interlocked. The threads/microblogs I've tried barely get responses (again, federation may be an issue), let alone even answers for even something like Blender. I can use Nim w/o art but I don't have the ideas for it usually (or if I do other issues happen, including just lacking the desire to write for something like a game book).
I've mostly waited for something to improve, but a while ago I started my own simple polygon loader/format and I worked a bit more on that today. I think I made one of my own questions irrelevant (assuming my condition to detect strip vs. fan is correct) and added a couple of other improvements. I don't think it's at a point I'd share it, but I probably could (should) try to make a simple game with it soon.
Though I'd rather have 3D in Raylib (vertex colors not working with Nim bindings, Naylib) or more advanced 2D in Godot 4 (no Nim-lang bindings, and said feature is an unmerged PR that may not be performant enough for full game art).
Tbh I wish the Lego communities on Lemmy were more active, aside from critiquing the odd announcement for a new set.
communities
There are multiple?
checks lemmyverse.net
https://lemmyverse.net/communities?query=lego
Looks like there's a number, but that !lego@lemmy.world is the only one that has much going on.
Probably not very popular, I miss the culture of r/morbidquestions that was the place to go for most weird topics without much judgment.
I would like an opera community.
the singing or the browser?
Singing!
TV, movie and book discussion communities aren't very active around here.

Miss the subreddits for all my favorite podcasts, Discord just isn't the same

Judo !
The Pikmin community!
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !pikmin@lemm.ee
Asklemmy
A loosely moderated place to ask open-ended questions
If your post meets the following criteria, it's welcome here!
- Open-ended question
- Not offensive: at this point, we do not have the bandwidth to moderate overtly political discussions. Assume best intent and be excellent to each other.
- Not regarding using or support for Lemmy: context, see the list of support communities and tools for finding communities below
- Not ad nauseam inducing: please make sure it is a question that would be new to most members
- An actual topic of discussion
