peep the inspo at the bottom
i finnally found some shit i lvoe
fuggg i hate to post this much because i'm certain my shit gets annoying. i bet there's hella people on here who view my posts as "fluff" and want it gone but highkey idgaf.
i know tildes likes to be open to discussion and likes to look deeper into things - ain't my fault i don't get that many comments ¯\(ツ)/¯. i tried writing more secretive and intricate shit people could pick apart if they want, but those weren't received as well as some of my more blunt posts.
though that one poem i did where i referenced rocky horror did really well.
i dunno.
i just hope my shit belongs here 😂 but i guess if i've been allowed to make over thirty posts in the past three months that means i'm in the clear.
dont be afraid to keep me in check, and dont be afraid to comment on my stuff.
i invite your questions, your critique, your thoughts in general. i may be fucxed in the head, but i'm an artist above all else (is that true?). if you want to dig into my shit or have any ways i can improve on my work, i'd be so glad to know you have no idea
i write my stuff to express myself but that does no good if no one's listening lmao so i want to write shit people like. i welcome all feedback.
anyway i'm ranting again and i'm only tipsy. imma finnish this drink (kuinka voit?), then imma find a beat and ride on some shit.
y'all know the drill.
say it with me.
esskeeetiiiiiiiiiiiiiiiit,
i'm actually crying right now. i found a beat that sounds just like the kind of shit i want to make and everything is just rushing to me. this is insane.
this is the blues moderna i want to make. i feel like Taj Mahal
ain't nothing truer in my heart
than missouri blues
remember driving through St. Louis
sitting next to you
remembering the times you said you loved me
guess it wasn't true
told me you'd love me forever
now i'm feeling all confused.baby where'd you go and why'd
you take my heart away from me
now i write pathetic songs and
can't stop thinking pitifully
wonder if you talk me good
or speak on me in mimicry
i can't stop hating myself
and looking at me criticallymirrors are the worst friend
a man could ever have
when a pretty blonde girl went
and tore his heart in half
when he's sure he's lived the best
years he'd ever have
what good is any man, girl,
without his better half?take me to the delta where
a man can sing in peace
laughing at me, drunk
when i'm just tryna find relief
can't afford the therapy,
for shit you did to me
i'd let you take my life if
you just killed me in your sheets(chorus)
baby please
tell me that you care a-bout me
promise you don't laugh at me
tell me that you'll come on close and hold me-.
baby hear me howlin' at your back door
wonder what you're not talkin to me for
hoping that you answer and take me home
take me back before everything went wrongtake me back to days when i still loved good
it was us against the world but girl we endured
our thoughts were caked in sin although our hearts pure
we got all cuddled close and smoked a backwoodtake me back to days when you still liked me
and my body wasn't cause for anxiety
wanna go back to twenty sixteen
eyes blue, hearts black, minds pristinebaby hear me howlin' at your back door
wonder what you're not talkin to me for
hoping that you answer and take me home
take me back before everything went wrong(chorus)
baby please
tell me that you care a-bout me
promise you don't laugh at me
tell me that you'll come on close and hold me
i feel like if i write any more on this one imma ruin it. i don't like that.

Hey Tildes, I got a job directly supervising a small team of 4 software developers. I'm very excited at the prospect and would like to put my best foot forward. To that end, I would like to have a discussion around a few topics. Feel free to expand the scope if you believe the conversation would be beneficial. I'm sure I won't be the last person to be in this position. I've done research, read, and watched videos regarding several of these questions; however, since Tilde prioritizes high-quality discussion, I thought it would be a fun opportunity to chat with others about these topics.
- As a member of a software development team, what are things that your supervisor has done that has had the greatest (a) positive and (b) negative impact?
- Supervisors, when you joined your new team, what was your methodology for reviewing the team, projects, and processes? What was the scenarios behind your review and the outcome? What would you do differently?

Sometimes one may knowingly add a comment that should be tagged as one of those, and sometimes I see people say (me included) things like "BTW this should be tagged <as such>." Maybe allowing a user to tag their own comment proactively with these three tags would be useful?
Edit: My main focus is the offtopic tag because I think that it's not necessarily bad or low-quality. Partially off-topic content can be very interesting and useful. Maybe I'm misunderstanding the use of that tag, was it intended for completely off-topic stuff in the first place?
Edit 2: I've opened an issue on Tildes Gitlab for this.

As mentioned last week, I've now deployed the bookmarking functionality that was primarily implemented as an open-source contribution by @what.
There's not much to say about it, it should be pretty straightforward: there are "Bookmark" buttons on both comments and topics, and you can view your bookmarked posts through the Bookmarks page, which is linked through your user page's sidebar. I'm planning to add the ability to search your bookmarks eventually, but I don't think that'll be urgent for a while until people start building up a pretty large list of bookmarked items.
Please let me know if you notice any issues with it, and thanks again to @what for the contribution!

A layperson's introduction to quantisation and spin, part 1

Introduction
I want to give an introduction on several physics topics at a level understandable to laypeople (high school level physics background). Making physics accessible to laypeople is a much discussed topic at universities. It can be very hard to translate the professional terms into a language understandable by people outside the field. So I will take this opportunity to challenge myself to (hopefully) create an understandable introduction to interesting topics in modern physics. To this end, I will take liberties in explaining things, and not always go for full scientific accuracy, while hopefully still getting the core concepts across. If a more in-depth explanation is wanted, please ask in the comments and I will do my best to answer.

Quantum OscillationsToday's topic
Today's topic will be quantisation, explained through the results of the Stern-Gerlach experiment which was first performed in 1922. This topic treats a much more fundamental concept of quantum physics than my previous topics.
What is the Stern-Gerlach experiment?
In 1922 physicists Stern and Gerlach set up an experiment where they shot silver atoms through a magnetic field, the results of this experiment gave conclusive support for the concept of quantisation. I will now first explain the experiment and then, using the results, explain what quantisation is. If you would rather watch a video on the experiment, wikipedia provided one here, it can be watched without sound. Note that I will dive a bit deeper into the results than this video does.
The experiment consists of two magnets, put on top of each other with a gap in the middle. The top magnet has its north pole facing the gap, the bottom magnet has its south pole facing the gap. See this illustration. Now we can shoot things through the gap. What do we expect would happen? Let's first shoot through simple bar magnets. Depending on how its poles are oriented, it will either bend downwards, upwards or not at all. If the bar magnet's north pole is facing the top magnet, it will be pushed downwards (because then north is facing north). If the bar magnet's south pole is facing the top magnet, it will instead be pushed upwards. If the bar magnet's poles are at a 90 degree angle to the two magnets it will fly straight through, without bending. Lastly, if the bar magnet's poles are at any other angle, say 45 degrees, it will still bend but less so. If we send through a lot of magnets, all with a random orientation, and measure how much they got deflected at the other side of the set-up we expect to see a line, see 4 in the illustration.
Now we'll send through atoms, Stern and Gerlach chose silver atoms because they were easy to generate back in 1922 and because they have so-called spin, which we will get back to shortly. We send these silver atoms through in the same way we sent through the bar magnets; lots of them and all of them with a random orientation. Now what will happen? As it turns out all the atoms will either end up being deflected all the way up or all the way down, with nothing in between. 50% will be bent upwards, 50% downwards. So silver atoms seem to respond as if they were bar magnets that either bend maximally up or maximally down. In the illustration this is labeled 5.
If we were to take only the silver atoms that bent upwards and sent them through the experiment again, all of them would bend upwards again. They seem to remember if they previously went up or down rather than just deciding on the spot each time if they go up or down. What model can we think of that would explain this behaviour? The silver atoms must have some property that will make them decide to bend up or down. Let's call this property spin, and say that if the silver atoms chose to bend up they have spin up, if they chose to bend down they have spin down. It seems that these are the only two values spin can have, because we see them bend either maximally up or maximally down. So we can say the spin is quantised; it has two discrete values, up or down, and nothing in between.
Conclusion
We have found a property of atoms (and indeed other particles like electrons have spin too) that is quantised. This goes against classical physics where properties are continuous. This shows one of the ways in which physics at the smallest scales is fundamentally different from the physics of everyday life.
Next time
Next time we will investigate what happens when we rotate the angle of the magnets used in the experiment. This will lead us to discover other fundamental aspects of physics and nature, quantum superpositions and the inherent randomness of nature.
EDIT: part 2 is now up here.
Feedback
As discussed in the last post, I am trying something different for this post. Talking about more fundamental quantum physics that was discovered 100 years ago rather than modern physics. Did you like it? Let me know in the comments!

When you label a comment, at the moment, you don't get any sort of feedback or indicator that you did so (or at least, I didn't). Maybe after you label a comment, and after Tildes has successfully registered the label, it could display something? Maybe like a little green circle or replacing the word "label" with something like "successfully labeled!"?

Yesterday @talklittle posted the topic Halloween game sales are live. What are your Horror/Halloween-themed recommendations?. There have been some good recommendations and whatnot. If you like horror games and weren't aware of the ongoing sales, go check out the comments for some recommendations.
Being the meta-killjoy that I am, I started this sidebar about the top comment. tl;dr: I don't think this type of content engenders Tildes's discussion forward community.
Fell free to read the whole thread of comments for some civil discussion on the matter, but I do want to open this up to all of Tildes: should this type of comment be policed on Tildes?
Also: do you think this type of comment is good? Do you agree with me that it's retroactive to Tildes's goals? Am I just a big killjoy? Given that the comment I'm calling into question is the top comment of that topic, I'm probably David in this arena but I want to hear it from everyone else.
