That's the first post this season about my "evenings and weekends" project, alt3.uk. That really is an unusual amount of apparent "home disadvantage" so far in the EFL Championship. I don't think I have seen anything like this since the covid times.

It's early days, of course...

I'm exited to announce a new resource about making slides with quarto and revealjs. This book is the combination of all the work I have done in this area, reordered and polished up

There isn't a lot of new information yet, but this format allows me to add more easily

The Royal Society has met to discuss Elon Musk – and they’re NOT removing his fellowship. They are criticising him publicly, but stopping short of actual removal.

This feels like the kind of compromise that will please *absolutely nobody*.

“I am increasingly concerned over threats to the values that allow science to flourish. Today at a meeting of the Royal Society’s Council, I led a discussion regarding some of those threats.

  

“Science thrives when individuals and institutions have the freedom to carry out research without fear of discrimination, censorship, or other restrictions that would hinder their work. In support of that, Council believes that it is not the role of the Royal Society to police the personal political opinions of individual Fellows and disciplinary procedures should not be initiated because of a Fellow’s social and political views.

 

“However, the Society can and will criticise Fellows who act in a way that runs counter to the values of tolerance, courtesy and respect for others that allow science to flourish. Elon Musk’s contribution to the ‘Unite the Kingdom’ rally is an example of a growing tendency towards the use of the language of violence, and narratives of division and polarisation. This language and these narratives threaten the values that enable science to thrive and the Royal Society rejects them, from wherever they originate.”

I’d double down. “Yes. I’m obsessed. He’s a fascistic, law breaking, populist, Russia aligned, dark money sponge. He’s leading in the polls. This is an emergency”

Right-wing media fluffs Farage for years, to the point where he now leads the polls, and then start whining about Starmer being 'obsessed' when he starts telling some long overdue home truths. It's actually hilarious.

We do this kind of research precisely so everyone can be better informed and the political and media narrative can get things right. It’s relevant for all parties, and free to read!!

These are particularly critical points that should be much better understood, not just by the government but also by political commentators, journalists, and broadcast bookers.

Nathan Gill is no fringe politician.

He was the leader of the Reform Party and before that UKIP in Wales.

A Brexit Party MEP.

A friend and ally of Nigel Farage, who in 2016 called him:

"terrific," and "as honest as the day is long."

This is a MASSIVE story

Trump at the UN:

"I look at London where you have a terrible mayor... Now they want to go to Sharia law."

This is entirely false. London Mayor Sadiq Khan is politically moderate and has never ever called for Sharia law.

This is Islamophobic propaganda and a bigoted attack on Khan.

The economic evidence is clear about what Americans can expect: Less innovation, less entrepreneurship, lower productivity.

A diminished future.

A useful reminder of what happens when due process is not followed. We have regulatory agencies with a breadth & depth of expertise for a reason (inc labelling). Look no further than the Kefauver-Harris Amendment (1962) & earlier Drug, Food and Cosmetic act (1938).

Impassioned plea for more mixed-methods research (quant & qual) from @timharford.ft.com

"The hard data is never as eloquent as a good story. Humboldt would measure the cactus but also sketch it; drag his barometer up a volcano, but spin a yarn about the epic climb."

A really neat paper thinking through what "Identifiability" means, how we can determine it, and implications for modeling.

Arxiv: arxiv.org/abs/2508.18853

#statssky #mlsky
A schematic showing some techniques for assessing identifiability and how computation-
ally expensive they are for computational models of different types, ranked in a typical order of
computational complexit A diagram of implication conditions between identifiability concepts discussed. Note
how structural unidentifiability makes practical identifiability impossible, both locally and globally.
Conversely, practical global identifiability, that may be (loosely) tested as described in the ‘Brute
force checks . . . ’ section, would guarantee the other identifiability conditions

It melts my head that X is still used for official Government communications, and, catching up on today's news and the fact we have a foreign billionaire inciting violence on our streets, it's clearer than ever that this should end.

I raised this in Parliament last week 👇
Question from me: "I warmly welcome the Leader of the House to his new role and associate myself with the support across the House for my hon. Friend the Member for Washington and Gateshead South (Mrs Hodgson). Members have raised many times the unacceptable level of threats that we face. Increasingly, abuse and threats are being driven and whipped up by one platform in particular, X, previously known as Twitter, which has become a sewer of antisemitism, racism, misogyny and dangerous conspiracy theories. Its owner has specifically targeted Members of this House. With a new director of communications in No. 10 and a refreshed Front Bench, may we have a debate in Government time on whether it is appropriate for that platform to continue to be used for official Government communications?" Answer from Sir Alan Campbell, Leader of the House: "What my hon. Friend says about X is truly shocking. We are very much in favour of free speech, but we are also against incitement to violence. We have delivered the Online Safety Act 2025 to seek to strike the balance between user protection and freedom of speech. On the matter of the Government’s use of X, it is right that the public are kept up to date with information and a number of people still use X, although of course many are moving to other platforms. I am sure that the Government will take that into account in our deliberations in future, and we also keep our wider social media practices under review."
