PM_ME_VINTAGE_30S [he/him]

Anarchist, autistic, engineer, and Certified Professional Life-Regretter. I mosty comment bricks of text with footnotes, so don’t be alarmed if you get one.

You posted something really worrying, are you okay?

No, but I’m not at risk of self-harm. I’m just waiting on the good times now.

  • Back on R*ddit, I actually managed to connect with a few R*dditors (under a different username tho) through the /r/BedroomBands sub. Looks like it’s still active. As far as I’m aware, we don’t have anything like that on Lemmy yet.

    From my experience in music, drummers are always in demand, especially if you can record your kit, even badly; real kit with sample replacement always beats an electric kit, which itself beats programmed drums. (And programming drums from scratch is so boring, speaking from experience.) So I think you’ll find people very quickly if you mention it.

    As far as my music chops go, I play guitar and bass, mainly metal, but I’m really more of a producer. Unfortunately, I had to stop taking clients from R*ddit because I had to focus on school. Now I’m living with my grandmother and parents so I can’t really do music stuff without headphones, so I’m kinda out of commission for a while.

    ps - I’m pretty socially anxious and autistic, so making friends takes me extra effort and time.

    Me too. It took me months to build up the courage to make my first post. But it was one of the best things I ever did, and I miss that part of my life dearly.










  • 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.






  • way more than $π million.

    I don’t need more than $π million. I just need enough to get some stuff started. I’m not interested in getting rich.

    I would also use the first loop to take medical tests of my health as much as possible since it wouldn’t matter if I went into debt in the first loop.

    Fair enough, but I really need the charm. I’m autistic and I’m not good at being social. I’d definitely be willing to give up a few years of life for more charm.
