Under UK law, a company can make £200m+ in sales and still hide its profit & loss by calling itself “small”.

That’s how PPE Medpro kept its finances secret.

A short thread on one of Britain’s daftest loopholes, the 1970s EU compromise that created it — and how to fix it.

As a former C user, malign obviously led me to think you had to align your data after malloc.

Happy to discover I was being needlessly triggered.

REPORTER: Gabbard has submitted a criminal referral. Who should the DOJ target?

TRUMP: It would be President Obama. And Biden was there with him ... the leader of the gang was Obama. Barack Hussein Obama. He's guilty. This is treason.

1. Kevin Gross and I just posted a new science-of-science preprint.

This one explores the looming peer review crisis. As many of you know, it's becoming significantly more difficult for journal editors to find scholars willing to serve as peer reviewers for submitted manuscripts.
Will anyone review this paper? Screening, sorting, and the feedback cycles that imperil peer review
Scholarly publishing relies on peer review to identify the best science. Yet finding willing and qualified reviewers to evaluate manuscripts has become an increasingly challenging task, possibly even ...

I absolutely don't love Labour focusing more on not losing voters to the right (on immigration, welfare, etc.) than the left, but a lot of people say stuff like "they are losing 2× as many votes to the Greens" without realising that one vote lost to a party that can overtake you is twice as bad...

Wow! Project Hail Mary is coming to the big screen! I had totally missed that this was coming... Here's hoping it can live up to the book.

@chelseaparlett.bsky.social have you seen?

My model was fitting just fine until I realised my data was only 320 of N=325.

Now it refuses to fit.

When is the next stop so I can get off this train?

This, but also if you are one of the academics that say data are available on request and you have actually provided it on request, go you! (Next time go even further and deposit it so you don't lose it)
gdeejay.bsky.social
In my experience, "Data available on request" is a useless claim.

I've reached out to a variety of academics that state this in their paper and one of the following things happen:
- Their email address is no longer valid
- Their whereabouts is unknown
- They don't actually reply to the request

Many of my left wing friends and colleagues would be surprised to see me taking this tone, as I am often the centrist dad in the conversation.

And for anyone arguing that private landlords leaving reduces the supply of private rented housing - it also reduces demand (almost) identically.
tmsnowsill.bsky.social
Absolutely. Many issues with 🇬🇧 housing are exacerbated by landlordism, rent-seeking in the truest sense.

I'm almost too angry to put in words all the ways their state-sanctioned greed has impoverished the nation. The situation can only improve by them rage-quitting.

Abject market failure.

The UK government must step in to protect jobs in #HigherEducation.

Voluntary and compulsory redundancies throughout the sector.

Staff costs have been squeezed for years - the sector needs cash. Either bring back international students, raise tuition fees, or reinstate block funding... Do it fast!

There is an academic theoretical paper I keep coming back to, and every time I read it I can't work out if I'm really dumb or the authors are really dumb...

No, I will not say which paper it is!

I do love this show. If you have time for only one Star Wars podcast a month, make it this one!

I am more enthusiastic than most for frailty models. When so much analysis outside survival analysis uses random effects it baffles me that we don't.

I think they have great explanatory power for things like accelerating then decelerating hazard at the population level.
tmsnowsill.bsky.social
For general survival analysis (not just parametric models) the Stata documentation st intro is great. Most of these are free online for slightly out of date versions.
tmsnowsill.bsky.social
Stata PDF documentation for streg is pretty good. If you want something with more maths the 3 page primer by Peter Treasure of Cambridge you can find by searching for "individual frailty gamma" is also good.
