Just saw a newspaper delivery car drive by and it had some sort of rail gun launching papers onto people's porches.

The Zelda movie had better be about the balance of nature and Mononoke/Nausicaa type shit. If it's another lame cash grab like the Mario movie I'm going to be very salty about it.

Sine, wasine, secant, wasecant, tangent, and watangent.
You kids and your six trig functions. Back in my day we had only one, and we used it for everything.
sin(θ)
sin(π/2 - θ)
sin(θ)/sin(π/2 - θ)
1/sin(θ)
1/sin(π/2 - θ)
sin(π/2 - θ)/sin(θ)
sin(θ)
sin(π/2 - θ)
sin(θ)/sin(π/2 - θ)
1/sin(θ)
1/sin(π/2 - θ)
sin(π/2 - θ)/sin(θ)

FIFO (first in first out) and LIFO (last in first out) queues are so CS 102. Today let's talk about the FAFO queue (fuck around find out).

Mastodon came through, gotta up your game mathsky 😘
Look at me I'm posting an image from another social network like a basic bitch.
But THAT social network has typesetting 😀 and so the post reads nicer than if I retyped it here with no typesetting.

I agree that STEM, the social sciences, humanities and all the rest need to stand together against anti-intellectualism.
I am also aware that when humanities funding was being collapsed, there was not a lot of STEM solidarity and there are STEM folks *now* still suggesting under-bussing humanities.

I’m so tired of this, man. We’re dealing with an all out war on intelligence and higher education. STEM and the social sciences and the liberal arts need to all stand together instead of this absurd petty squabbling.

Not being an AI-doomer, but having experienced in my own department over the past 7 years a steady erosion of faculty governance norms and diminished prioritization of research-oriented pedagogy, this tracks. Let faculty and faculty interests lead the way, rather than administrators/regents
"AI returns to the university as part of a broad effort to further corporatize universities, vocationalize higher-education instruction, and diminish both research and research-based pedagogy."

NGL I love this part of train trips. Get a sleeper car, dine with a rando, have a conversation with someone out of the ordinary.
Thing I didn’t expect on a train trip- Amtrak seats strangers together like Benihana, only it’s just a table for four so it’s obvious when you’re not talking. Every…single….meal, new people.

The wealthy are not moving away, and everyone is getting free childcare.
This article has a lot more important problems so I feel stupid saying this…but umm…the Mercury wrote and published the first major article about the DSA councilors back in June. Of course it isn’t the local reporting linked or mentioned here.

But also, just make it a fucking website! If the app is designed in a half decent manner, this should be easy.
This is the obvious absurdity of pulling ICEBlock. It is obviously legal, protected speech for anyone to say, in any forum, “I just witnessed some police activity at location X”. Indeed, people have been doing this regularly on social media since its inception.
"I think in a free country we should be able to post onto the internet, 'hey, there are masked agents on Broadway and Vine and not have the government or the tech oligarchs prevent us from doing that.' Shame on you, Tim Cook."

Every time someone posts about how inconsistent some Republican talking point is, I want to shout, "THEY DON'T CARE"
Pointing out hypocrisy doesn't achieve anything, and just allows them to control the discussion and distract from what matters. Ignore it and reframe.

I liked my Google home mini, until bit by bit it got worse at its core function (set a fucking timer) and now it's a brick. Can't imagine buying a new one based off Gemini, because what's to stop that one from becoming another brick?

Honest question: why don't people make and share email blocklists, and build up some basic automation around adding to them and syncing them? Surely people like this are few but noisy, and people could preempt voluminous email harassment quite easily.
