@camwilson Somewhere was a post screenshot of someone posting "'I asked ChatGPT! I asked Grok!' Oh yeah? Well I asked Gandalf and he said he had not passed through fire and death to bandy words with witless worms."
This is what a human hand looks like under a microscope.

"Trapping AI" – Operational Progress! 🕳️

Following the last update (https://tldr.nettime.org/@asrg/114742667183459482), we’re transitioning from planning to practice — amplifying both the scale and operational ferocity of our approach through the deployment of a new, more radically interventionist layer of complexity.

This intensified escalation — as outlined in the last update — is concretized in fakejpeg, which is now fully live and operational. From this point onward, every page generated by our standalone LLM crawler-tarpit embeds a garbage JPEG. Notably, within just a few hours of operation, this deployment has already yielded over 40,000 such images.

The integration of fakejpeg constitutes a critical deepening layer that amplifies both the strategic offensiveness and subversive ardor of our approach by enabling the ongoing targeted poisoning and coordinated dissemination of systematically crafted junk data within the operational workflows of AI systems.

Welp. Between this and the earlier AI-"written" book, I am thisclose to recommending that we cease purchasing titles from Springer

https://retractionwatch.com/2025/06/30/springer-nature-book-on-machine-learning-is-full-of-made-up-citations/

"Based on a tip from a reader, we checked 18 of the 46 citations in the book. Two-thirds of them either did not exist or had substantial errors. And three researchers cited in the book confirmed the works they supposedly authored were fake or the citation contained substantial errors."

Would you pay $169 for an introductory ebook on machine learning with citations that appear to be made up? If not, you might want to pass on purchasing Mastering Machine Learning: From Basics to Ad…

@dalias It's sad. LLVM has actually been officially tainted: https://github.com/llvm/llvm-project/commit/632151fbeea972f4aa3c14921eca1e45c07646f3

While digging, I found they actually *allow* AI slop: https://llvm.org/docs/DeveloperPolicy.html#ai-generated-contributions

Guess it's time to drop LLVM everywhere. I would consider using *any* of it a complete risk.

Okay. No more procrastinating. The moment is here. The code is officially public, the builds are built and uploaded, and the documentation is written (more or less, it's deeply imperfect of course.)

The first version is
2025.6.29-2. If you've been curious, you should follow the getting started/installation instructions here: pho.spookygirl.boo/w/media-thing/

Unless you've got an account on spookygirl phorge (which I have plans on opening up somewhat) the best way to tell me about problems is by DMing me or commenting.

Not knocking the joke, but...
My appendix scar is in the centre, just below my ribcage.
I had a stomach operation and they removed my appendix while they had me open!
@wyliecoyoteuk @hleb likewise. When I had my appendix removed I was curious about where my scars were. "Is the appendix not on the right?" "Oh, it's not in a fixed position, it's usually in that general area but not always."
@dtwx @hleb
In fact, most organs are partially mobile, especially your intestines. So when they open you up they can reach quite a lot from a fairly small incision.
Even more in these days of keyhole surgery.
In fact my recent heart op was carried out from an incision in my wrist!
@hleb reminder that the most unhinged (but apparently correct?) thing to do is to ask the monkey machines to double check their answer....
@hleb And then it cuts on the left side again.
@nazokiyoubinbou @hleb and then with the same response again: dude, you're 100% correct. Let me try it again.
@hleb do not hallucinate or you go to jail.
@hleb I'm at a stage of my life where I forward AI memes to my mother in law and I'm so here for it.
