Wulfstan II’s Complaints of ‘Unlagu in the North’ One of the most prolific late Old English writers, Archbishop Wulfstan II of York ‘Lupus’ (d. 1023), is particularly known for drafting law-codes for King

Mini-article out now Open Access in Notes & Queries – take a look for my theory of what Wulfstan II means by ‘injustice in the north’ (spoiler: Vikings and weird legal stuff in the Danelaw) doi.org/10.1093/note... #Medievalsky #Medievalists

Super niche #earlymodern query: has anyone ever worked with account books that are records of salaries received by specific individuals?

I've a prioress and her steward both making these payments. The individual verifies receipt and then signs. The book is a running tally of these disbursements.

Firmiter credimus: The Changing Dynamics of Lay Belief

Humanistiska teatern
19 March 17:15
Free entry, all are welcome
Contact: gustav.zamore@uu.se

The Fourth Lateran Council (1215) begins with a statement of faith, 'We firmly believe...' (Firmiter credimus). But what did it mean to ask the laity to believe firmly? This talk addresses not only what medieval people were asked to believe but how they were 'to believe.' It will be argued that the spectre of lay doubt troubled authorities as much as the more famous threat of heresy.

Cuailnge (‘The Cattle Raid of Cooley’) is a nineteenth-century manuscript copy of the most famous Irish narrative of the Middle Ages. Although its oldest surviving copies were produced in the twelfth century, the story of the Táin is set in the first century, and it has been argued to have been written in several periods in between. This talk will highlight the dual significance of this beautiful manuscript by exploring the history of its contents, the physical object, and its creator, Seosamh Ó Longáin, the last official scribe of Ireland.

Hey ChatGPT, write me a fictional paper: these LLMs are willing to commit academic fraud Mainstream chatbots presented varying levels of resistance to deliberate requests for fabrication, study finds.

'All major large language models (LLMs) can be used to either commit academic fraud or facilitate junk science, a test of 13 models has found.'

All versions of Claude are 'the most resistant to committing fraud'.

Which LLM is your university encouraging students to use most? Asking for a friend.

GOP congresswoman wants to ban strippers in schools but can't name a time when that happened - LGBTQ Nation She instead said that the ban would actually apply to books that mention LGBTQ+ people and ban any mention of trans people in schools.

In 1954 the village of Châteauneuf-du-Pape passed a municipal ordinance forbidding "cigares volants" — flying saucers — from taking off, flying over, or landing in the village.

To their credit, not a single UFO has landed in the southern Rhône since that day.

Screen cap from the New York Times AI promotion, sorry I mean article, "The New Fabio is Claude". They call the thief using AI to make money on the works of other people a "writer". Future Fiction's is a company that produces AI slop based on stolen texts. Hence it wasn't West who came up with a plot, it was someone else, that the AI theft machine stole from. 

The quote is:

"The writer Elizabeth Ann West, one of Future Fiction's founders, who came up with the plot of "Bridesmaids and Bourbon", believes the audicence would be bigger if the books weren't labeled as A.I. The novels, which are available on Amazon, come with a discolaimer on their product page: "This story was produced using author-directed AI tools."

"If you hide that there's A.I., it sells just fine," she said."

So, I can see some reasons for this.

People know AI is theft and don't wanna pay you for stealing.

People don't like they way AI theft macines put out words.

Not noticing without lables might be because if you buy a book, it's too late. Doesn't matter if you realise it's AI. You already payed.

A putto is sitting on an early modern type case, a box made for the different types during the hand-press era. One needed to pick up each type for a letter or symbol etc. and compose each word, text, and page. The putto blows also soap bubbles: in each bubble is a letter, and the word formed is VANITAS, meaning "vanity". This detail was published in a German speaking newspaper, "Monatliche Nachrichten einicher Merkwürdigkeiten" in 1751. VD18 90722892.

Ex-Meta lobbyist put in charge of EU's digital rules: 'Tech oligarchy writing its own rulebook' Pressure is growing to drop the appointment of a former Meta lobbyist, elected as an MEP in 2024, from a file which could rewrite the EU's regulation of US tech giants.

Moderaternas partigrupp i EU, EPP, är känd för att gå i lobbyisternas och storföretagens ledband.
Men det här är ändå något av ett rekord. Metas främste lobbyist ska ta fram lagstiftning om EUs digitala regler.

Grovt språk fyller en viktig funktion i att ge uttryck för känslor som är fullt rimliga i det här fallet.

Kristersson är en korrupt liten bedragare och ett principlöst svin, som inte ens blinkar inför att förstöra liv, och det bör sägas högt och ofta.

Snubblade över Wikipediaartikeln om gnagaren Oligoryzomys microtis, som verkar sakna trivialnamn på flesta språk.

Förutom tyska, som har tagit ansvar: Kleinohr-Zwergreisratte. Småörad dvärgrisråtta.

Bra namn. Allting med den här gnagaren är litet. Uppfattat.

In the Holocaust, Jews faced a continuing series of laws forbidding them to do certain activities & occupations. The goal was to remove them from society. The US is now doing this to trans ppl. Generally, once one State brings in such laws, others follow.

My introduction to the law took place when I was a child & discovered my being gay was a crime with a jail sentence [or worse, walled up in the Central Mental Hospital to be experimented on]. As a result, like many minorities, I realised that the law was about oppression & not rights [1]
