The total lunar eclipse last night from Fairbanks, Alaska with a searing bright aurora right overhead. Insane combo.

AI-generated art canโ€™t be copyrighted after Supreme Court declines to review the rule A lower court previously said that โ€œhuman authorship is a bedrock requirement of copyright.โ€

If AI-generated art canโ€™t be copyrighted, then AI-generated code... this could get interesting

Maybe so! But I'm not sure I had even heard of Highlander II before going to college in 1994, so I think there's still a chance that the idea may be prone to arising independently when someone doesn't like a sequel.

I've been pretending "Mostly Harmless" doesn't exist ever since it came out in 1992. I have no idea if I got the idea from other people, or if it's just a common instinctive reaction to sequels that don't work for you.

The savings we're getting here by annihilating decades of American science will pay for whole minutes of the operation to create decades of death, immiseration, and chaos in Iran.

Sarah Vaci is a "gender critical" artist who set out 4 years ago this month to create 100 portraits of "female detransitioners." To date, worldwide, she hasn't even found 100 to take part in her project, and at her current rate, it will take her 10 to 15 years to finish.

Why is this important? 1/

really one of the strangest media cycles in history, where mainstream media actively hid the fact that the columbine killers were popular upper class preppy kids with full on neo-nazi ideologies and instead pretended they were victims of bullying

Picture of Marjane Satrapi alongside a quote from her. The quote reads:

The world is not divided into countries. The world is not divided between East and West. You are American, I am Iranian, we don't know each other, but we talk together and we understand each other perfectly. The difference between you and your government is much bigger than the difference between you and me. And the difference between me and my government is much bigger than the difference between me and you.

And our governments are very much the same...

- Marjane Satrapi, Iranian-French graphic novelist

For people who still care about this sort of thing, here's James Madison writing from 1793 (6 years after the delegates in Philadelphia signed the Constitution) about why the power to make war was vested in the legislature.

[I'm quite tempted by the idea of having this raft of legislation ready to go as soon as the next Democratic President is elected, and making it clear to Republicans that the new President will gladly sign those laws, but until then they will unilaterally reshape government just like Trump did.]

I hope that someone somewhere is already putting together detailed plans for what the replacements for all that should look like. This is a vast amount of work, and whenever there's finally a Congress prepared to act on it, they will need as much of a running start as we can give them.

It's also clear that SCOTUS has invalidated the core premise of a huge amount of 20th century legislation that established independent agencies to have nonpolitical experts shape policy: unless those decisions are reversed, that entire structure needs to be scrapped and rebuilt from the ground up.

I've been uneasy for years about the many "emergency" powers Congress has given to the executive. (A memorable grad school lunch conversation was "Could the President just wake up and nuke Cuba?") Between Trump and SCOTUS, I'm getting convinced Congress should revoke them *all*, despite the risks.

I wonder what strategy will actually work. I desperately want laws to prevent gerrymandering, but the GOP was dead set against them as long as they were the main ones doing it. My hope now is that if both sides see it as a danger, they might fix it.

Maybe executive power needs the same thing. Ugh.

This is an excellent article about the value and purpose of genre fiction *and* it also neatly summarises how literary fiction works and what it doesn't address.

The screenshot of the release notes reads:

A new version of TeX Live Utility is available!
TeX Live Utility 1.55 is now available-you have 1.54. Would you like to download it now?
Release Notes:
Changes Since 1.54
โ€ข Fix bug 137, homepage link in Help Book.
โ€ข First release in a long time, since I don't use TeX anymore and resent the very idea of paying Apple annually for the privilege of giving away free and open-source software. Also, I'm really lazy. Please accept my apologies for all the annoying issues you've encountered in this mission-critical software.
โ€ข Updated mirror list, which was three years out of date.
โ€ข Added missing legacy mirrors, which was even more out of date.
โ€ข Added an alert on startup when user tries Homebrew's lobotomized MacTex, because those lunatics left timgr but removed its database.
Thanks for nothing, guys. Bug 142 and 144.
โ€ข Use a custom user-agent to work around the Anubis bot trap on texlive.info. Can't wait to see what else breaks because of this, thanks to the profusion of degenerate Artificial Insemination fetishists scraping websites to feed their models.
โ€ข Lists of countries in Repository/Continent are now sorted. No idea how you people let me get away with that one for the last fifteen years.

There's a "is anyone even reading this" sort of honesty you get in the software update release notes from a project that's been around for a long time.

Wait, really? I've never paid to publish in high-energy physics or in physics education. (And particle physics even has a collaboration SCOAP3 that's negotiated for the main journals to be fully open access, too: libraries of big institutions pay for that instead of for individual subscriptions.)

Pretty wild Ai result, that will probably get less press than the latest Ai boyfriend article: arxiv.org/abs/2602.21201

A benchmark was created with professional mathematicians, using problems naturally encountered in their research and not publicly released. Aletheia solved 6/10 autonomously.
