@cassavanse
hi! It is I, casavanse. Or, well, it used to be. And then i did a very smart thing and lost access to my previous account (@/casavanse). so, really, it is I, cassavanse.
ive sent a message to tumblr support, but i don't really know if they can help (since, well, it really is my fault). in the meantime, im trying to rebuild everything again, so if you followed me on my old account i'd be really happy if you'd follow me on this one again :)
What I want for Pride Month
I'm already in love with the concept, and I'm wondering how magnetism and besides that radiation might could come into play in systems like this? I wanted to write a story about a planet that's so heavily magnetic that it just jams everything, how would that work? If not by magnetism, what would it be?
Not remotely covered by the system generator but I have snagged the physicist about it and got them talking because this is a fun question so:
Earth's magnetic field is in microtesla so even a pretty little increase will have an effect
Anything that involves moving electrons around will be affected - in power transmission, for example, electrons aren't moving all that fast but the charge is travelling at about two thirds the speed of light.
An electromagnetic wave (like light or radio waves) is half in the magnetic field so if your background magnetic field is strong enough you'd get something happening, but whether that's a block or an amplification is a question for a different kind of physicist.
Exactly how the magnetic field increase affects your signal transmission is out of field for either of us sorry.
Very good question!
Hi! I am taking my final exam for electromagnetism ii tomorrow at 3:30. So I’m not like an expert but I have had some recent experience.
My instinct is to say that actually the magnetic field probably wouldn’t do much provided that it’s constant or roughly constant with time; light is a pair of oscillating electric and magnetic fields, but because of the principle of superposition, light can still travel through electric and magnetic fields because the oscillation remains, it’s just that the ‘zero state’ shifts. That is, instead of oscillating between, say, positive and negative 35 nanoteslas (ie the strength of the magnetic field due to sunlight at the surface of the earth, according to this Reddit user (https://www.reddit.com/r/askastronomy/comments/1m96yjo/solar_magnetic_field_strength_at_earths_surface/) (I. Don’t want to do the math right now.)), it would oscillate between, say, 20.003 and 19.997 microteslas. However, this is exactly what happens on Earth, and we can still get sunlight and radio waves. Basically the same thing would happen on this hypothetical planet; the only way it would interfer with light is if it were also oscillating on a similar timescale- which is to say on the order of around a trillion times a second. This can’t happen due to a spinning metallic core, but if the planet were putting off blackbody radiation due to heat, I could conceive of that being sufficient to ‘jam’ some frequencies. However I’m not sure if that would happen at the desired frequencies at reasonable temperatures. This may be a case where you need to apply a little bit of Artistic License and do it anyways.

@kissysanguine was hoping this would happen, expressing uncertainty summons an expert :)
Hiiii i took a physics class this past semester that had a unit basically on this so I have some hyperspecific comments to add.
TLDR: A strong magnetic field around a planet is going to make your space weather situation ~funky~ (with consequences).
Ignoring solar wind effects, a breathable atmosphere means that there will be a plasma formed around your planet that will move along/interact with your planet's strong magnetic field. This has the potential cause some problems with communications both on-planet and between planet and space, since waves of certain frequencies can't pass though a plasma the same way they do normal atmosphere and empty space.
A planet that for whatever reason cant communicate with the outside solar system and therefore has to rely on physical mail, even in a GFFA type universe where space travel is commonplace, is a super fun concept imo. Snail mail planet.
Links below if you're curious, showing some of the differences between planets with strong/weak mag fields and a short one about Earth's magnetosphere that talks a bit about the impacts on space travel at the end.
Mercury has a weak magnetic field, while Mars and Venus have no measurable magnetic fields. Jupiter is the largest planet and has the strong
FAQ to date and answers I have managed to get out of the generator's creator (who is extremely offline, bemused by the attention, and deeply flattered if slightly concerned):
This is a freebie and is being written as a side project by a very busy physicist and apparently distributed as a side project by a very busy rocket scientist, this blog is gonna be sparse on the updates.
Yes it's coded in Matlab yes we know you hate Matlab.
At some point the creator (I'm gonna have to ask them what pseudonym they want because I can't keep calling them 'my beta' but again we didn't think this would happen) is intending to code this up as a .exe that users can run directly if they trust us or compile themselves and then run if they don't. This person is way more computer than I am and I'm more computer than much of Tumblr so yes this is a high bar to entry.
Yes the intention is to publish the code when it's working properly, and I'm trying to convince them to set up a github page. It's going. Badly.
At the moment it's generating random star systems beautifully, though the smaller moons keep phasing in and out and you have to check the readme to find out what the numbers mean. Generating planets to spec is stickier just at present and will be a longer time coming.
Their intention is to send me a working copy of the random generator to post sometime on Friday, so realistically you won't see that before the weekend because I have a life too and y'all are killing my notes.
Yes EVENTUALLY you should be able to input any of the parameters the generator allows for and it will output a system that meets your requirements, but I anticipate spending a LOT of time deliberately breaking it before that's up and running.
To the person who offered debugging help, I love and appreciate you but this person learned to code fortran and assembly before anything else and makes new code languages for fun so I do not think you will be able to read their code (no shade, I can't either).
Yes it can do binary systems, I have the printout for one, but again it is currently sitting in a state of 'this is an unformatted Matlab output' and requires reference to the index/readme/glossary to puzzle out what the numbers mean.
Have you considered checking with the devs who work on the World Orogen generator?
(Which for those who dont know is a planet generator that literally generates a planet with tectonic activity and a generalized idea on mountain ranges and even climates. So i can see potential in expanding further)
@frowny-clowny you're looking for this.
To answer - no, this is the first I'd heard of this thing, I'll mention it to the physicist but I suspect actually making the two compatible will be out of scope because this was intended as a small one-off and absolutely not something that would get or need ongoing support.
We uh. Were expecting maybe 20 people to be maybe mildly interested in seeing it in a few months.
On the autism site? How many orders of magnitude were you off by?
Three. Oops.
normal people in SF are fucking sick of every billboard being for AI slop
takes a real artist to go "i have to deface this billboard promoting an evil corporation's evil product. but crucially☝️the typeface and kerning must match or else it's cringe"
"why do men watch porn instead of just having sex with their girlfriends?" is already silly for numerous reasons, but seeing it being used as like. a feminist talking point is so crazy to me because like of the implication that being in a relationship means being available for sex all the time, which you know. doesn't feel great for women i think.
“It’s photoshopped” honestly in the age of AI that has a homey sort of nostalgia to it. Remember when people used to put effort into faking things?
photoshop fakers are like the villain with moral standards now
This may be the best Pride merch I've seen from a major corporation.
Levi's said yes, actually. Assless chaps and a biker vest. Happy Pride.
And the assless chaps sold out on June 1.
They also specifically contacted members of the leather community, used them as models iirc, and donated $100k to Outright International. They talked the talk and walked the walk and put their money on it too. I don't really care that I can't afford and don't want this merch, I love to see my community getting the respect it deserves. Levi's said, "We make jeans which gays wear lots of jeans? Oh leather daddies? Let's call them."
I think Levi's donates to Outreach International every year too, as well as sponsoring pride events and other community support. They were offering Same Sex domestic partner benefits to employees in the 90s, and have been very public about their support for pro-lgbt legislation all through the 2000s.
So, you know, a giant corporation that walks the walk pretty consistently.
They also this past year contributed some pretty decent prizes for one of the challenges in the new drag king reality competition series King of Drag - They're definitely walking the walk right now.
I’m was watching a video about a Jewish custom, and the entire comment section was like this
It’s about anti Zionism my ass.
This is the case whenever a post has Hebrew/ Jewish symbols/ etc. it’s obviously not about Israel.
It’s been a while and this just happened again so here are the comments under a video about traditional clothing for orthodox Jewish men
Dozens of hateful antisemitic comments & so many “free Palestine”
Is this antisemitism? Yes.
But these people don't think they're being antisemitic, they think they're arguing for a group of people being oppressed by an apartheid regime, which they are. The main issue at play is that the genocide in Gaza fosters antisemitism in people who are not antisemitic, because Zionists are belligerently intent on inextricably tying Israel to Judaism.
When the Zionist propaganda says Jews = Israel, and the news shows us that Israel = genocide, people will inevitably think Jews = genocide.
The only way to fix this is to stop the genocide and teach people not to conflate the Jewish faith with the actions of the Israeli government.
I love how it's always the fault of those darn Zionists who are tricking the hapless masses into being antisemitic, so those same people never have to take respinbility for their own bigotry
I love how even in your mealy-mouthed lukewarm defense of Jews you can't conceive that the people accusing random Jews of killing children aren't actually trying to innocently criticize Israel, and they're not only being antisemitic by accident
newsflash, dumbfuck, the people who come onto a post about Jewish customs and ask them how many babies they've killed don't "think they're arguing for a group of people being oppressed by an apartheid regime." they think they're attacking Jews whom they view as responsible for Israel's actions, not because of "Zionist propaganda" but because they're racist assholes who are looking for simple explanations to the world's problems. same as always
Bigots always have a story about how they're in the right and their hatred is good and just and righteous. That's...part of the bigotry, in fact.
The fact that this person could say the sentence "fostered antisemitism in people who are not antisemitic" and still think that any of what they're saying makes sense is astonishing.
In today's example of what happens when much of a generation mistakenly believes they can become educated through memes and reels:
Let's be precise about what @queercodedangel got wrong.
What the IRD list actually was:
A private notebook, handed to one person at the IRD, listing individuals Orwell thought were unsuitable to write anti-stalinist propaganda - not people he wanted arrested, surveilled, fired, or harmed - and none of them were.
Orwell believed these specific people were Stalinist sympathizers who would undermine the work of countering Stalinism. You can legitimately think that was a bad call - it was certainly a morally complicated one for Orwell. It was not, however, the act of an imperialist snitch. It was the act of someone who hated authoritarian Stalinism enough to do something uncomfortable about it, while continuing to publicly criticize the British state.
The tension between those two things evaporates the moment you understand Orwell's position: Stalinism wasn't socialism. It was fascism with better branding, and it was destroying the socialist project from within.
History proved Orwell right.
Orwell:
Got shot through the throat while fighting fascists in Spain
Spent decades producing some of the most devastating critiques of British imperialism ever written, including Burmese Days, and Shooting an Elephant.
Called himself a Democratic Socialist his entire adult life and meant it.
Wrote that "every line of serious work I have written since 1936 has been written, directly or indirectly, against totalitarianism and for democratic socialism."
@queercodedangel is taking one late-life episode, stripping it of all context, and canceling one of the sharpest anti-totalitarian, anti-imperialist pens of the twentieth century - because he wouldn't excuse Stalin's crimes. That's apparently the price of admission to the 2026 left - being ignorant enough to deny that Stalin was a monster.
Calling that "snitching" tells you nothing about Orwell. It tells you that for some people, anti-Stalinism is a greater sin than imperialism ever was - and you can only take that position if you know nothing about what Stalinism was.
That sucking vacuum of ignorance where actual knowledge should be doesn't inspire a single second of hesitation before they confidently preach provable falsehoods. The less @queercodedangel knows about Orwell, the IRD list, or Stalin's crimes, the more confident the verdict. This is what happens when a generation decides memes and reels are sufficient substitutes for actually reading anything.
Orwell spent his life fighting this kind of epistemic laziness - the willingness to flatten complex realities into politically useful, emotionally resonant, self-affirming fictions.
This is why Gen Z desperately needs to read the Orwell and Huxley they've been told to avoid.
There hasn't been a generation in living memory simultaneously more vulnerable to propaganda and more thoroughly convinced they are completely immune to it.
they should make a wetter water that hydrates you 5 times as much. it should feel like a videogame health potion. instant healing. instant hydration.
Why can the Internet not just spontaneously create new fic for me when I run out?
Not like that! I didn’t mean it like that!
