"Nearly 80 years later, the simplex method is still among the most widely used tools when a logistical or supply-chain decision needs to be made under complex constraints."

only half followed the description of the simplex method in here but super interesting anyways

Parents, please check your kids’ candy this Halloween. I’ve just found an ancient metal whistle with the inscription “QUIS EST ISTE QUI VENIT" inside a Snickers bar. I blew it and heard a note of infinite distance, and now I’m haunted by a figure in pale, fluttering draperies. Be safe.

How many times, in how many contexts, from how many internal and external researchers, or from how many CEO's are people going to have to receive this message before they believe it:

"Hallucinations" are an inherent part of the large language model architecture.

Can researchers stop AI making up citations?
OpenAI’s GPT-5 hallucinates less than previous models do, but cutting hallucination completely might prove impossible.

It's seeming likelier and likelier that AI really could eliminate a lot of jobs very soon. Just not in the way boosters have suggested. www.theatlantic.com/economy/arch...
Just How Bad Would an AI Bubble Be? The entire U.S. economy is being propped up by the promise of productivity gains that seem very far from materializing. By Rogé Karma The capability-reliability gap might explain why generative AI has so far failed to deliver tangible results for businesses that use it. When researchers at MIT recently tracked the results of 300 publicly disclosed AI initiatives, they found that 95 percent of projects failed to deliver any boost to profits. A March report from McKinsey & Company found that 71 percent of companies reported using generative AI, and more than 80 percent of them reported that the technology had no “tangible impact” on earnings. In light of these trends, Gartner, a tech-consulting firm, recently declared that AI has entered the “trough of disillusionment” phase of technological development. By one estimate, Meta, Amazon, Microsoft, Google, and Tesla will by the end of this year have collectively spent $560 billion on AI-related capital expenditures since the beginning of 2024 and have brought in just $35 billion in AI-related revenue. OpenAI and Anthropic are bringing in lots of revenue and are growing fast, but they are still nowhere near profitable. Their valuations—roughly $300 billion and $183 billion, respectively, and rising—are many multiples higher than their current revenues. (OpenAI projects about $13 billion in revenues this year; Anthropic, $2 billion to $4 billion.) Investors are betting heavily on the prospect that all of this spending will soon generate record-breaking profits. If that belief collapses, however, investors might start to sell en masse, causing the market to experience a large and painful correction. The dot-com crash was bad, but it did not trigger a crisis. An AI-bubble crash could be different. AI-related investments have already surpassed the level that telecom hit at the peak of the dot-com boom as a share of the economy. In the first half of this year, business spending on AI added more to GDP growth than all consumer spending combined. Many experts believe that a major reason the U.S. economy has been able to weather tariffs and mass deportations without a recession is because all of this AI spending is acting, in the words of one economist, as a “massive private sector stimulus program.” An AI crash could lead broadly to less spending, fewer jobs, and slower growth, potentially dragging the economy into a recession. The economist Noah Smith argues that it could even lead to a financial crisis if the unregulated “private credit” loans funding much of the industry’s expansion all go bust at once.

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.
1/n
Abstract: Under the banner of progress, products have been uncritically adopted or even imposed on users — in past centuries with tobacco and combustion engines, and in the 21st with social media. For these collective blunders, we now regret our involvement or apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not considered a valid position to reject AI technologies in our teaching and research. This is why in June 2025, we co-authored an Open Letter calling on our employers to reverse and rethink their stance on uncritically adopting AI technologies. In this position piece, we expound on why universities must take their role seriously toa) counter the technology industry’s marketing, hype, and harm; and to b) safeguard higher education, critical thinking, expertise, academic freedom, and scientific integrity. We include pointers to relevant work to further inform our colleagues. Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI (black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf. Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al. 2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA). Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.

this iconic advertising copywriter named Kathy Hepinstall Parks died over the weekend and I wanted to share something from her website I thought Bluesky would like
Why should I write better when a machine can do it for me? Because actually no one can do it for you, because your voice is unique among all the people on earth. Siri never petted a horse's neck. Alexa has never been ghosted by the captain of the football team. But you have lived, your heart is beating, you have suffered, and you have something important to say. It's a human's job, to use words, and whatever job you give to a machine, that part of your brain goes dark. Maybe it's worth it when it comes to remembering phone numbers and directions, but when that part of your brain that uses words goes dark, that's a vast area that's very close to your soul. Don't let some internet platform convince you that what you have to say and create isn't worthwhile. Words are the echo of your soul. Honing that echo matters.

I don’t know who needs to hear this, but news / social media—especially when constant, chaotic, and unfiltered—can hit our brains like a DDoS attack: overload attention, flood emotions, and make it hard to think clearly.

It’s okay to step back and curate what you let in. Your mental uptime matters.

1. LLM-generated code tries to run code from online software packages. Which is normal but
2. The packages don’t exist. Which would normally cause an error but
3. Nefarious people have made malware under the package names that LLMs make up most often. So
4. Now the LLM code points to malware.

Automatically updating content can be extremely distracting, especially for users with vestibular disorders or attention difficulties. This could force users to scroll through page content to not see the animation, or to just look away. Allow animations to be paused or stopped.

One of my favorite moments of last night’s event was the young woman who said she was starting to write, and asked how to balance a day job with a writing career.

And I felt the call spark within me, and I leaned forward with my soberest eye and said, “I am the worst person to ask about this.”

I'm a great fan of the Holmes Basic D&D, and the inclusion of the B1 module, "In Search of the Unknown." It leads on story and creativity over number crunching. If I'd started with the Red Box, I'm not sure I'd have persevered with RPGs.

No. The point is that it doesn't have to be something big. The recipient is under no obligation. By saying it has to be something big you're back to making people feel helpless.

Put a hat on a baby. Buy someone a sandwich. Do something small.

Ok so here's what I'm mad about today.

The invisibility of disabled people.

There are invisible disabilities (altho frankly they are not that invisible, we're just working our asses off hiding them) but you can be hella obvious and people don't notice.
