I wrote a Blender plugin that uses vector math, matrices, calculus, trigonometry, and likely other types of math. There's recursion, filesystem access, image processing, interface logic, and on and on.

And worst of all - other people are expected to use it, so there's added pressure to do a good job.

Oh, the hours I spent trying to figure out why the imported geometry looked like an exploded mess. Fumbling around with mathematics I didn't fully understand was exhausting. Finding help was impossible at times because I didn't have the vocabulary to even describe the problems I was having. And getting it to complete an import before the heat death of the universe was not easy.

Every time I made progress and thought I was done, I would discover a bug that other importers didn't have, leaving me to sift through languages that definitely aren't Python to see if I could reverse engineer the logic they used.

I almost gave up a few times, but didn't.

Now I have something that, while not used by many people, works very well, is very efficient, and doubles as a palette cleanser when I need to do something for fun or for a challenge. Plus I learned a lot along the way.

I love mathematics so I love programming.😃

I have found that once you work for a company where you have to implement everything in its raw form using the raw language and raw logic, you really have to know what you're doing and knowing some basic/medium programming and having some algebra knowledge doesn't cut it (unlike some people think).

I've been at two sides of the coin: I worked for a company that had everything in place, a framework that handled all edge cases and what not and I just had to focus on user stories, but I also worked for a company where I had to do everything manually.

For example, at the latter company I had to know Discrete Mathematics; truth tables to their most convoluted and disgusting form, having to be able to apply this on a late Friday night with a headache and lack of food and sleep with the PM stressing out.
I've had to deal with NOT AND OR AND OR AND OR AND branches or whatever, where an OR behaves like an AND and if you want a value between an AND AND and an OR, you'd have to do a NOT OR.. to think about latches, all in my head, sigh, anyway, within limited time constraints, without even having time to write tests, having to make sure that everything checks out while the client is breathing down my neck. Yeah, not such fun times.

I'm happy for those of you who can just write some moderately difficult logic but you don't have to break your head over doing everything manually, as if you're in the coding stone age and nothing is taken care of.
Companies like these make me want to run away.

- I love blowing my mind. Even if it is the most confusing thing. Things like security mechanisms, neurons' behaviors, mathematics (even tho I hate it when I fail lol), electronics, medical terminology and chemistry.
- I love collecting rare coins, personally never-seen stones and put them into my collection. I love to be a designer. Not only on my laptop. I have a book shelf and within that book shelf I put stones that create the yin yang sign while pushing the books to two sides. That makes them look like they are levitating. I have stones (including obsidian) that create a triangle and a knife hanging down the wall of my room.
- I love visiting touristic, historic, naturally-beautiful but also non-touristic (non-touristic? yes. by that I mean visiting e.g. the areas of touristic cities which are dangerous, because you can easily fall down off of a slippery ground and take serious injuries) places around the globe, talk to complete strangers in public (I am trying to be an extrovert), take pictures with my camera and collecting antiquities.
- I love taking risks (no. I don't play any poker games etc on the internet) without trying to put other people in risk. Driving insanely with whatever I have. Car, bike, you name it.
- I love reading books. Books that are about human psychology, fantasy novels and books about programming languages.
- I love to cook (I am at the beginning).
- I love to use the konMari method of tidying up my room.
- I love plants.
- I love having everything in my room tidied up (even if I am too busy with other stuff and skip this cleaning process for a week upto a month sometimes. Sorry, room.).
- I love doing sports. But mostly sport that I have never tried before. This can be, because of my greedy wish for an adrenaline kick. That led me into taking a balloon flight at 4 am (sunrise) and to paragliding at sunset above Mediterranean sea btw. (I am normally afraid of flying, but paragliding was awesome).
- I love swimming. Like, you cannot pull me out of the sea for a minimum of 2 hours, if it is not important.
- I love laying above the sea water and let the sea carry me to somewhere else.
- I love being alone. I love the silence. I love to be free in my thoughts.
- I love watching the sunset, the light that shines through the forest, the moonlight and the stars at night.
- I love dreaming. No, like, lucid dreaming for example.
- I love being open to any opinions.
- I love to learn about other people's views about the world and their religion.
- I love pets and would do anything to keep them alive when they are ill. It hurts my heart seeing them like this.
- I love watching demonic "A: Holy shit! Did you see this thing, too?! B: Yes!" YouTube videos just for the fun of it, but I hate horror movies and games.
- I love trying out new things. The creation of music and video for example.
- I love to give my hair and beard a shape, if I am too lazy to go to the barbershop lol. By that I don't mean just going to the barbershop, but taking an electric razor and cutting my hair myself even if I get bad results from time to time that can be corrected by letting any family member tell me in which area of of my head the hair problem is.
- I don't like disco clubs.
- I don't like toxic people even though I can be a quite toxic person myself without realizing it. If I appear toxic to you, inform me about it. Having so much testosterone in that moment, can make me do things that I don't want to do.
- I don't like drugs even tho I have to admit that I am trying a few from time to time (maybe 6 months in-between) to have a dopamine kick. I am not an addict.
- I hate myself for things that I did in the past.
- I used to watch MMA videos etc.
- I used to use a telescope, but I can't find it anymore.
- I used to have a microscope, but I can't find it anywhere and besides of that the seller did literally piss in it before selling it to me many years ago. Don't want to touch it tbh.
- I used to play games, but I don't enjoy games anymore. That makes me feel sad.
- I miss the old moments of my life.

In conclusion:
I like how things went and go so far. It changed me so much. It made me a good and a bad person. I became more open and confident, but it also particularly made me a leader who can say "fuck off" in a bad way to his family. I would like to undo this particular part of me.

A friend of mine studies mathematics and he told me about a project he has to do and we worked on it together a bit: Numerically calculate the arctan.
He dug out a nice series by (the one and only) Euler and we started massaging the thing to get it into a bit of a nicer form (there were (n!)^2 and other shenanigans) and we eventually succeeded after some stupid simple errors and arrived at a quite simple recursive progression. After that he also found a formula to transform a given value into the region where our formula actually mimics the arctan and we proceeded to proof this formula. The programming was straight forward and now we only have to find the radius of convergence which I suspect is pi^2 (but no proof).
I had a lot of fun doing this, fiddling around with the formulas and then programming it to see it actually becoming real.
