Are there any R users that have experience with Linux and can recommend minimum hardware requirements/Linux distributions for R? No different to windows for hardware requirements and compatibility? @frame.work laptops are unfortunately sold out till late in the year.

$1,000,000,000,000's isn't worth $30/month.
AI is simply a tool that allows me to do what I could already do faster.

A fabricated dataset hosted on Kaggle was recently removed for breaching copyright, months after it was exposed in research led by #AusHSI PhD student @alexdgibson.bsky.social with @aidybarnett.bsky.social, @nicolewhite.bsky.social and Gary Collins. Find out more 👇

I’ve not been excited about technology in a long while. @frame.work modular, upgradable, repairable laptops have got me SO EXCITED. Respecting consumers and the planet will always wins. Putting my MacBook up for sale and making an upgrade!

Yeah, that's not good. Having looked into how a lot of medical guidance etc gets made manually, it doesn't surprise me. But it's not good.

Some of the models seem to have been used in clinical settings although it’s not clear whether this has led to flawed diagnoses go.nature.com/3Q7scE0

Dozens of AI disease-prediction models were trained on dubious data
The models are designed to predict someone’s risk of diabetes or stroke. A few might already have been used on patients.

Outstanding work by @alexdgibson.bsky.social to uncover the use of highly dubious data sets from @kaggle.com being used in hundreds of research papers and potentially even informing clinical practice. If you're re-using data, take the time to confirm that it's real. www.nature.com/articles/d41....

We need more people reading more books! Such an important skill and has done so much for me. There’s nothing better than a good book, a change in perspective, beliefs or the generation of new ideas.

Ok, time for a short thread about this paper. My sense over the past six months or so is that chain-of-thought prompting as used in e.g. ChatGPT o.3 improves substantially upon previous systems such as ChatGPT 4.o, at least for certain tasks. But how revolutionary is it?

Reading over my brother’s undergraduate assignment. Criteria has a section: “Is there an appropriate amount of detail in this section so that you could replicate this study?” I don’t remember learning about replication in my undergrad! Nice to see it getting some air time.
