I just learned that oat milk was discovered in the 1960s, when NASA found out by accident what zero-g environments do to goat milk.
Thank you, thank you, I'll see myself out.

Ma et al 2026: "Do Coding Agents Reuse Existing Code or Reinvent the Wheel?" https://arxiv.org/abs/2609.35357 "An audit over 3,000 turns shows that agents progressively stop exploring relevant repository code, reuse their own history less even when it is fully in the workspace, and leave duplicated logic in 50.8% of task chains by turn 5 - all while pass rates barely move."

I think you have to be very naïve to believe that AI providers aren't (at least occasionally) skimming information from users' prompts.

Four days ago, a scientist was surprised by the news that Anthropic discovered new virus genes for making DNA. He says he’s been studying them for years—and feeding his data to Anthropic’s AI as part of his own research. Coincidence? Here’s my story. https://nyti.ms/3VSWayc

parton (n.): unit of measure for the extent to which a wealthy person uses that wealth to make the world a better place. Sadly, the milliparton and microparton are more commonly used. Note that negative values are frequently observed.

In his essay on Salvador Dali, Orwell argued that because Dali was a repulsive human being, the right wouldn't admit that he was a great artist; conversely, because he was a great artist, the left wouldn't admit he was a repulsive human being. I'm seeing the same thing with AI: because it's unethical, one side won't acknowledge that it's useful, but because it's useful, the other side won't acknowledge that it's unethical.
Time to make another cup of tea…

Looking for source of quote: "The real purpose of AI is to give the wealthy access to skill without giving the skilled access to wealth." thanks in advance (please note: not in search of commentary at present time)
Please help if you can: I am working with some students who are studying programmers' beliefs about software engineering folklore. If you can spare a few minutes to answer the question in https://survey.bth.se/survey/2545 we would be very grateful. We would also be grateful if you could circulate the survey link to colleagues and friends - we would like to reach as diverse a demographic as possible. Thanks in advance.

Suppose you discovered that AI transcription mistakenly ascribed points made by women to male participants in meetings 40% of the time - would you continue to use it? What if it was 4%? Or 0.4% (i.e., once every 250 meetings)? Do you and/or your employer have a threshold or SLA? Are you/they even thinking in those terms?
When exactly did setting up a dev environment on a new machine become functionally indistinguishable from solving crossword puzzles in Ancient Sumerian?
I had the privilege of reading a pre-release draft of @grimalkina@mastodon.social 's "The Psychology of Software Teams". Serendipitously, I followed it with Sarah Stein Lubrano's "Don't Talk About Politics", which is actually about the psychology of how people change their minds (or don't). The combination gave me a _lot_ to think about, and I highly recommend both.

There is an alternate timeline in which the Jupyter notebook was built in OpenOffice instead of in a browser, so that people could (for example) draw diagrams directly in the Office-y parts of the doc beside their embedded code cells. It wouldn't have played nicely with version control, but neither (in practice) does Jupyter's fastidious JSON and embedded images. I still wonder sometimes what kinds of coding environments would have evolved from that…
I remember reading a science fiction story in the late 70s by Poul Anderson in which an aging capitalist and an aging communist come to blows in a bar in a small town somewhere in the not-very-distant future, arguing about where it all went wrong. Turns out that as soon as solar became really, really cheap, both of their economic models just…went away, along with the belief systems they'd sustained. The younger townspeople don't even really understand what they're arguing about…
On December 22, 1967, Spock asked the Enterprise computer to calculate pi to the last digit in order to paralyze it (episode 2x07, "Wolf in the Fold"). Is this the first example of prompt engineering in modern fiction?

Today, LLMs are spitting out shell commands that use all the available tools, because that's what their training data does. I wonder how long it will be until we see a new, more cohesive set of command-line tools that truly follow the Unix philosophy: each does exactly one thing, RISC-style, and the power comes from ever-greater composition. That, plus the "everything is structured data" philosophy of Nushell, would be an interesting future (albeit unlikely). 2/
edit: OK, so it's a way to hand government money to their more radical supporters. That (unfortunately) makes sense.

Thanks to everyone who has responded / is responding / responds in future. Several of you have had questions or comments about the survey's content - I can't answer them now for fear of biasing responses, but I'm taking notes and will do so once the survey closes. The results and analysis will be published (open access) as soon as we have them. Thanks again.
