The Labour government's response to a summer of open racism, including physical attacks and the demonisation of some of its own Cabinet, has been to hide. 'Anti-racism' is something you actually have to do, not something you are. Seriously, why can't people like this hear themselves?
Ouch. I’m talking about a general approach, not a single instance. And I think you’ll find, as a generalisation admittedly, that Labour supporters are anti-racism.

Python: The Documentary | An origin story
This is the story of the world's most beloved programming language: Python. What began as a side project in Amsterdam during the 1990s became the software powering artificial intelligence, data science and some of the world’s biggest companies. But Python's future wasn't certain; at one point it almost disappeared. This 90-minute documentary features Guido van Rossum, Travis Oliphant, Barry Warsaw, and many more, and they tell the story of Python’s rise, its community-driven evolution, the conflicts that almost tore it apart, and the language’s impact on... well… everything. Thanks to our sponsors for making this documentary possible: Anaconda: https://www.anaconda.com/ @AnacondaInc.

Britain has no idea - in terms of its self-image, not economists obviously - what economy it actually has
One of my favourite facts to point out is: at over £8bn annually, the *videogames industry* is more than twice as valuable to the UK economy as fishing and steel combined.

Men are extremely keen to explain to me that Britain *needs* a domestic steel production plant and doesn't necessarily *need* universities. Okay. Steel contributed about £1.7bn to the UK economy in 2024. Universities contributed more than £200bn.

“The damage this has done to our country is incalculable.” This sentence would feel right at home in some of the 1970s Monday Club/National Front material that I read for Imperial Island.
If you thought the PM’s speech was punchy, his foreword to the immigration white paper says high net migration has done “incalculable damage” to the country.
That is a serious shift in tone for a Labour government/party.

The govt’s planning reforms are a strong start—but key questions remain:
1⃣ Will homes have the right infrastructure?
2⃣ Can govt afford to build new towns?
3⃣ What part of the housing crisis are they solving?

Trans women are women and no court judgement can change that. Without wanting to diminish the negative effect that legal oppression has on trans lives, there is no reason why lawyers and judges are qualified to make this argument over actual experts in the field.

British Steel employs 3.6k people. Coventry Uni group, which auditors say may not survive, employs 7.7k. But there is an emergency debate in parliament for British Steel and nothing for the whole HE sector imploding
Why is the government and the news so indifferent to the meltdown happening in UK #HigherEd right now?
Our universities are the envy of the world. Yet we are at risk of losing a generation of academics and damaging the sector beyond repair.
