I think it’s plausible that, under the right conditions, life is common, but intelligent life is rare (it took billions of years on Earth). Without fossil fuels a sustainable industrial revolution might be next to impossible so industrial civilisations are even more rare.

People have been predicting the end of the world for some time and they’ve all been wrong so far. When the world failed to end in 1844, the Millerite movement called it β€œThe Great Disappointmentβ€œ. I don’t suppose that sentiment was widely shared.

Yes. Melanoma is not the most common cancer in Australia but the others appear later. So when you restrict the picture to under-50s you get high peaks in Australia but also N Europe. Data from the IARC Global Cancer Observatory gco.iarc.who.int/en

Absolutely unbelievable to see egregious anti-science nonsense being given an airing like this. Well done @lewisgoodall.com for calling it out. β€œA broad church… freedom of speech” - and that’s the excuse for platforming not just misinformation but disinformation.

The β€œproblem” with vaccines? They so effective at preventing deaths that they create generations of people that question whether disease was a problem in the first place because they have never experienced the horrors of a world without vaccines.

Image of a poster to be presented at the Royal Statistical Society conference in Edinburgh, September 2025.  The main point is to generalize the idea of a ternary plot to handle 4-part compositions, by showing views through the triangular faces of a tetrahedron.  The data shown are vote counts from England, Scotland and Wales in the UK General Election of July 2024.

At next week's RSS conference I'll be presenting a poster (a first for me...it's about time!)

"Tetraplot displays of UK General Election results" shows how to graph GE 2024 vote shares across 4 parties in a useful way.

It can’t give you advice because it doesn’t know anything. It’s a synthetic text generator that responds with a statistically plausible continuation of the context window based on the training data. @infinitescream.bsky.social

Deal to get ChatGPT Plus for whole of UK discussed by Open AI boss and minister Exclusive: Deal that could have cost Β£2bn was floated at meeting between technology secretary Peter Kyle and Sam Altman

Kyle [secretary of state for science innovation and technology] has been a vocal champion of AI … he had asked ChatGPT for advice on a range of work-related questions, including why British businesses were not adopting AI and what podcasts he should appear on.

This explains why Peter Kyle wants the Turing to focus on defense and security research which a) belongs in the public sector and b) is in the national interest.

It's a narrow view of the national interest but it answers the existential question.

The problem with creating a centralised research institute is that you have to answer the question "Why here? Why can't this be done elsewhere?" Caught between industry and the university sector, the Alan Turing Institute is having a hard time answering.

#rstats I just submitted a new version of the {heplots} pkg to CRAN and got the message below.

It's August, and the #CRAN maintainers deserve a break, but it seems to me they also deserve a vote of thanks for all the work they do in vetting updates and new packages in R.

If I wanted to do this, I would add NA tags as a separate attribute of the data frame, not try to augment the numeric vector class.

I think that tagged NAs are useful for data management but not necessarily for computation. You could extend the data frame class to allow tagged NAs, preserve them during data manipulation operations, and allow selection and transformation based on the tag.

The TESCREAL Bundle The Distributed AI Research Institute is a space for independent, community-rooted AI research, free from Big Tech’s pervasive influence.

To some extent, yes. Critics of big tech have identified a pervasive set of cultish beliefs driving the AI industry that they call the #TESCREAL bundle.

Even if you have hardware and compiler support for NaN payload propagation, you still have to implement the semantics of NA vs NaN vs finite value propagation in all low-level arithmetic operations. Extending these semantics to include tagged NAs is too much complexity, and not guaranteed to work.

NA_real_ in #rstats is implemented on top of IEEE754 arithmetic as NaN with a particular payload (1954). This seemed like a good idea at the time. Unfortunately, there is no guarantee that NaN payloads are propagated. It happens to work - mostly - on the platforms R is mainly used on.

This is a joke from A Fish Called Wanda used to illustrate the stupidity of Otto (Kevin Kline):

"When he learned that your daughter's name is Portia, he said 'Why did they name her after a car?'"

They’re going to switch it on and ask it if there is a God aren’t they?

I’m only half joking. A lot of tech bro behaviour can be explained by my theory that they desperately want to live in the SF world they read about as kids and are just pretending that they are bringing it into being.

GPT increasingly feels like the next evolution of Gladwellian non-fic. Gladwell’s great trick was that you could flatter the reader’s ego by dressing up banalities and oversimplifications in a way that made them feel clever, like they were accessing special wisdom. This is the interactive version.
