LaTeX: typically let software decide for me, override if it looks bad.
Paper: Too shit at writing to make a consistent choice
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.
Alt account of PM_ME_VINTAGE_30S@lemmy.sdf.org. Also if you’re reading this, it means that you can totally get around the limitations for display names and bio length by editing the JSON of your exported profile directly. Lol.

For integrals, we would say that “b and a are the limits of integration”.
The notation “lim x->0 1/x” would be read as “the limit of 1 over x as x goes to zero.” In general, “lim” is short for “limit” of whatever follows it, with respect to what is below the “lim” symbol. Rarely, I have also seen the notation “l.i.m.” used for the limit in mean, i.e. the limit with respect to the L^2 norm.
Unfortunately I’m an engineering student so my mental illness isn’t allowed to matter 🙃
I think this is quantum mechanics. Ψ(x) is the wave function of some quantum object (like an electron) as a function of (1 dimensional) space, U(x) is the potential as a function of space. Ψ(x) is a generalization of the state of a particle (a vector in a real space) for quantum mechanics (to a complex function). The squared magnitude of Ψ(x) can be interpreted (with suitable normalization) as a probability that the object will be measured to be located at x. The plot here actually shows the real component of the wave function; in general, it is complex, and it is complex in this situation.
Classically, if something is on the left side of the barrier created by U(x), it shouldn’t be able to cross to the other side at all without being supplied external energy. Intuitively, imagine that I roll a literal ball to the right. You would expect it to bounce back at you. However, in quantum mechanics, it totally can appear on the other side of the barrier. Why? Based on the graph, the wave function has some nonzero magnitude on the right side of the barrier.
So this meme implies that some of the swords are going to appear on the other side of the wall.
Me trying to hang out with literally anyone including people I’ve known my entire life
I try to be, but I’m probably not close enough to my siblings (or anyone for that matter). I just don’t want them to get sucked into the miserable void of despair that is my personal life.
Okay, you first /s
Quantum computing becoming practical for ordinary people.
If my employer forces me to use that specific software, then I care. Thankfully I’m unemployed.
I’m not sure, but I don’t have trouble carrying it. It’s so big because sometimes I have to bring in projects and/or test equipment.
When not in school:
When in school: all the above plus:
Wireless headphones get extra priority because they allow me to control what I hear. For example, instead of getting sensory overload (I’m autistic) at the supermarket, I can replace it with death metal, which is better for some reason.
Just because you’re personally tired of hearing about it doesn’t mean it’s wrong
End of Millennial or first of Gen-Z, although I feel a lot more like Gen-Z.
I live in an area that got “smoked” during the Canadian wildfires last July. I found out by reading about it on Lemmy. Only then did I look out the window and realize that it wasn’t sunset. I’m such a shut-in that I found out about the event I was in the middle of by reading about it on the internet.
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.
Yes. Can’t find work so I definitely can’t afford to move out. I moved out briefly during college and while it was unsustainable, I was so happy nonetheless.
Amazon Fire Tablet 7in. I bought it literally just to read PDFs, and it was so slow that it was basically unusable. I tried switching out the launcher to something more minimal (Niagara launcher I think), and I figured out how to disable the ads that were all over the place. It helped a bit, but not enough to overcome the hardware and Fire OS. (I think I needed ADB for both of those fixes; I had to put in some real work to unfuck that tablet.) Plus the screen was too small for my pathetic human eyeballs.
Was it worth $30? At the time, yeah, because I literally couldn’t afford anything else, but I now have an $80 10in generic Android tablet that’s wildly faster.
Best answer, although I work with delta “functions” a lot so I actually have to be careful picking which interval with boundary {a,b} to pick (for example, if I integrated δ(t-a)+δ(t-b) over all t in (a,b), I’d get 0, but if I integrated those deltas over (a,b] I’d get 1, and integrating over [a,b] would give 2).
Also I do have to do integrals with parameters and multiple variables so I can’t really leave out the differential.
