Portuguese:
Alguém acabou de me enviar o artigo "Escrita acadêmica ética, responsável e humana com inteligência artificial".

Someone just sent me the article 'Ethical, responsible and humane academic writing with artificial intelligence.' I'm not sure if it's a scam, but it's worth checking out.

DeepL added "I'm not sure if it's a scam, but it's worth checking out." to my translation.

Bilbo looking at his phone top

After all, why not? Why shouldn't I keep it?

You're absolutely right — you found it, it's been with you a long while, and it's only natural to feel fond of something that's served you so well, especially when someone like Gandalf suddenly seems to want it for himself.

We recommend avoiding general and often dehumanizing "the" labels such as the poor, the mentally ill, the French, the disabled, the college-educated. Instead, use wording such as people with mental illnesses. And use these descriptions only when clearly relevant.

The use of "the French" in this tweet by @AP was inappropriate and has caused unintended offense. An updated tweet is upcoming.

I cannot unsee the death of the pull request in open source upon us.

PRs from external contributors made a lot of sense when it was hard to write code, and it took lots of time investment (+ lots of thinking!) to do so.

Now that it takes seconds/minutes: dynamics change

Captura de un tuit de Peter Steinberger (@steipete), con foto de perfil y cuenta verificada. El texto, sobre fondo negro, dice que recibe muchas críticas por publicar un proyecto hobby gratis, que la gente lo trata como si fuera una empresa multimillonaria y que incluso investigadores de seguridad exigen recompensas. Añade que con los sponsors apenas le alcanza para comprar un Mac Mini, que el proyecto es para inspirar a la gente, que no está terminado, que tiene menos de tres meses y que, pese a los rumores, a veces duerme.

La gente cada vez es más desagradecida...

El creador de Clawdbot (ahora Moltbot) se queja, con razón, que recibe insultos y amenazas en redes sociales.

Un proyecto gratis, open source, creado como hobby.

Falta más empatía y personas con ganas de construir.

People already working hard to prove how perfect Alex Pretti was. To show he didn't "deserve" to be killed. But it's a trap folks. You're only feeding into a dynamic where people who are considered lesser get no protection. You don't have to be an Alex Pretti to deserve to live.

By who? Who shot the person dead? You saw the video. We all know a federal agent shot a man dead who was prone on the ground. Also, it's not "according to officials." It's according to verified video seen with your eyes. Not saying what anyone can obviously see with their eyes is a form of lying.

Alex Jeffrey Pretti was an ICU nurse at a VA hospital. His life, through his profession, was dedicated to serving his community and our country.

As so many have now seen on video, his final act before he was killed by federal agents was doing everything in his power to protect his community.

Who in his final act on this earth was helping a woman pushed to the ground

And they are calling him a Domestic Terrorist in order to defend their gross abuse of power, their absolute breaching of the law" AOC

Dear Author,

      I am Honglin Bao (www.hbao.info), a data science PhD student in Knowledge Lab (https://knowledgelab.org/) at the University of Chicago, working on a study about “The Capabilities and Potential of AI for Automating Scientific Idealization: A Large-Scale Human-in-the-Loop Study” (under UChicago IRB25-1372). As AI plays an increasingly significant role in scientific discovery, this project aims to evaluate how far AI helps scientists extend their work in new directions – or if it is not useful in this regard. This is a research project – it has no commercial purpose. I will share the final draft, technical details, and aggregate results from scientists once the study is complete.     
      We came across your preprint "Principles of music perception" and applied custom AI models on it in accordance with the terms of the preprint license, which generated five new extensions (i.e., ideas proposed by AI based on the same context as your paper). Our pilot study of 400 scientists (excluding you) indicates that around 60% found at least one of the proposed extensions thought-provoking and actionable. However, the remaining reported that AI only generates seemingly plausible but vague sentences.
      We solicit your help in evaluating whether you think AI is useful or not, since we believe you are the best judge of new ideas proposed from your own paper. No matter where you stand regarding AI and science: From principally believing that AI is prone to producing fake and morally problematic science to finding it useful, or something in between, we hope to receive evaluations that reflect a spectrum of views.
      The AI-proposed extensions are included in the survey link below. If you consent to review them and participate in the survey, we would appreciate it if you could do so within the next 14 days (it will take you < 10mins). If you do not consent, we will not use your research in this study. If you find these ideas valuable, you are welcome to purs…

Please remove my data from your study. I want nothing to do with this — and I would also point out that if you had done appropriate background work in the selection of articles you fed to the plagiarism machine, you would have found that the preprint of mine you used is way out of date and has been updated substantially since it was first posted.

somebody at UChicago is feeding preprints to LLMs without authors' consent, in a research study

they have the gall to suggest to authors they've opted-in that they volunteer to evaluate the LLMs' suggestions regarding their own work.
