  7. Posts about dysphoria/trauma/transphobia should be NSFW tagged for community health purposes.

  8. When made outside of NSFW tagged posts, comments about dysphoria/traumatic/transphobic material should be spoiler tagged.

  9. Arguing in favor of transmedicalism is unacceptable. This is an inclusive and intersectional community.

  10. While this is mostly a meme community, we allow most trans related posts as we grow the trans community on the fediverse.

If you have any questions, please ask. I love yapping.

yapLet's say we have some periodic function f. The goal is to represent it as a bunch of sine waves. This is called a Fourier series (FS).

The FS coefficients are given by

            ⌠2⋅π
         1  ⎮         -i⋅k⋅x
f̂(k) =  ─── ⎮   f(x)⋅e       dx
        2⋅π ⌡0

for whole numbers k. We can then approximate the original function with

  n
 ___
 ╲          -i⋅k⋅x
 ╱    f̂(k)⋅e
 ‾‾‾
k = -n             

and make the approximation better by making n larger.

For non-periodic functions, we can still get an approximation! The Fourier Transform (FT) uses a continuous range of frequencies instead of whole numbers, and the sum is replaced by an integral (the inverse FT).

FT's are used everywhere, for example in signal processing and spectroscopy. If a recording contains an annoying high-pitched noise, we can apply the FT and filter the unwanted frequencies. Spectroscopy separates light into its different wavelengths. By comparing the resulting spectral lines with known measurements, we can determine which elements and molecules are present in stars and planets, for example.

idk what more to add ._.

As a reminder, please do not discuss current struggle sessions in the mega. We want this to be a little oasis for all of us and the best way to do that is not to feed into existing conflict on the site.

Also, be sure to properly give content warnings and put sensitive subjects behind proper spoiler tags. It's for the mental health of not just your comrades, but yourself as well.

Here is a screenshot of where to find the spoiler button.

Did my injection. Need to figure out where to hide all my shit. Also, is it okay to use the same alcohol wipe on the top of my vial and then on my injection site? I only have 10 left. Not sure if I have any isopropyl alcohol I can use instead.

dysphoriaI hate being trans. I hate my body and voice. I hate having to come out. I hate surgery worries. I hate my life in general. I wish it wasn't like this. I don't know how to cope with it. It feels like I can't. I just wish I was happy and okay. Why does being trans have to be so difficult. I want the dysphoria to stop. The suffering. This is all a nightmare. Being trapped in the wrong body with the wrong voice.

I do the same thing lol, at work I use seperate ones (theres no shortage there) but for my own injections I tend to wipe the top of the vial and my tummy with the same wipe. For what its worth, you can use soap and water for your stomach and a good scrubbing - doesnt have to be alcohol wipes.

Okay, thank you. I was hoping for your input.

It shouldn't be an issue. Sometimes it takes so long for me to get the E out of the vial that the wipe has dried out, so I end up using another one anyways though.

Okay cool. The guide I watched a while ago said to use two and I wanted to be sure. Being a little inconvenient is fine to help me stretch it longer. Thank you.
