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.

  • simultaneously blame democrats … for having too much government reach and action on immigration and the border AND THEN turn around and complain that they are too soft on the border and immigrants are just flying through.

    I don’t think anyone around here thinks that Biden’s being “soft” on the border…or that we should even have a border in the first place…

    The phrasing “too much government reach and action on immigration” (because they should have none, which neither party offers) and “soft on the border and immigrants are just flying through” (because any maintenance of the border is unacceptable, whether “soft”-looking or not) really shows how silly it is to try and pigeonhole everything into partisan newspeak. Let’s say it like it is: borders suck and all of us here (I hope) are going to criticize any party or group that wants to continue hurting people because of them, regardless of who they claim to represent.

    it’s sooo cool to blame Democrats (and apparently liberals…

    I mean yeah it totally is lmao.








  • 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.



  • IMO LyX is way simpler than LaTeX for basic stuff, but because it is literally not Microsoft Word I couldn’t really use it to collaborate with people this semester, let alone convince them to work on a full LaTeX document. LyX would be the way to go if my colleagues were even remotely interested in learning about literally anything. You can lead a horse to water, but you can’t make it drink…


  • 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.
