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.















  • Infinite-dimensional vector spaces also show up in another context: functional analysis.

    From an engineering perspective, functional analysis is the main mathematical framework behind (1) and (2) in my previous comment. Although they didn’t teach functional analysis for real in any of my coursework, I kinda picked up that it was going to be an important topic for what I want to do when I kept seeing textbooks for it cited in PDE and “signals and systems” books. I’ve been learning it on my own since I finished Calc III like four years ago.

    Such an incredibly interesting and deep topic IMO.


  • I actually designed a digital equalizer using an IIR filter this semester, which actually does theoretically work on sequences of numbers, which constitutes an infinite dimensional vector space. The actual math was just algebra and programming, but it was an implementation of a Z-transform transfer function which is a sequence operator (maps input sequence to output sequence).

    IMO infinite-dimensional stuff shows up in two types of problems:

    1. For some reason, you need to solve the partial differential equation you started with, i.e. you can’t use symmetry or approximations to simplify it into an ordinary differential equation.

    2. When you’re dealing with signals that change in time or space, you have to decompose those signals into simpler signals that are easier to analyze.


  • I don’t judge anyone by their weight, but it’s sure hard to direct that same acceptance toward myself.

    Yeah same here, but I’m at a weight where I’m exceeding weight limits of things like ladders, furniture, etc. And I’m in terrible physical shape on top of all that. It’s really more of a “tactical” thing for me at this point. Just gotta get it done.

    Sounds like you’re doing well, though.

    Thank you. Could be better, could be a lot worse. I’m still a social disaster.

    And I make my own frozen meals

    Me too. The other day I made like half my meals for the entire summer in one giant cook.


  • Do most people generally eat the same things all the time?

    Yeah. IMO variety is expensive because it’s usually cheaper to buy a few things in bulk.

    consulting a professional before doing so.

    I consulted a nutritionist before doing my first weight loss [1] because I wanted to make sure my diet was nutritionally sound. Surprisingly, it was fine, just too much of everything. Very surprising considering that I’m a picky eater with texture issues, but I’ll take it.

    In contrast, my sister had to see a nutritionist to go on hormones and apparently her diet was nutritionally whack, so she had to make a bunch of changes.

    vegetables

    Please God no (at least not raw)

    [1] I put it back on when I went to engineering school, but I managed to keep it off for a couple years. Oh well. I’ll get around to losing it again soon.
